Description
[0001] The invention relates to a packaging machine according to
the preamble of claim 1, as well as a data storage medium according
to the preamble of claim 9.
[0002] Use of a packaging machine in a business requires operation
by a number of people. These include, among others, operating
personnel who run the equipment, and also service personnel who
monitor and repair the machine with respect to safety and
functional capabilities. In addition, riggers are frequently used
to set up, adjust, and prepare the packaging machine for use.
Furthermore, programmers are needed to modify the control of the
machine, for example, as well as other personnel, e.g. who carry
out installation and modification work on the machine. In order to
prevent risks, operating errors, or even accidents on the packaging
machine, it is important that the individuals carry out only the
operations entrusted to them, or that they are capable of
performing in the case of servicing activities.
[0003] It is well-known from the prior art how to regulate access
to such machines, or access to a servicing device for the machine,
by means of a locking device that can be operated by a key. Insofar
as computer-assisted servicing of the machine is provided,
logging-in with an access password is also enabled in commercial
machines.
[0004] The object of the invention is to propose a packaging
machine in which logging-in to gain access to the packaging machine
is accompanied by the smallest possible expenditure of time and
effort.
[0005] This objective is achieved in a packaging machine of the
foregoing type through the characterizing part of claim 1, as well
as through a data storage medium according to claim 9.
[0006] Advantageous embodiments and improvements to the invention
are possible by means of the measures specified in the
subclaims.
[0007] Accordingly, in a packaging machine according to the
invention having at least one registration device, a log-in device
in particular, at least one of the registration devices for
checking the personnel-related access authorization includes a
reading unit for receiving information transmitted in a wireless
and/or contactless manner from wireless or contactless readable
portable data storage media.
[0008] Persons working on the machine and/or those servicing the
machine are thereby equipped with said portable data storage media.
A variety of embodiments are possible for such data storage media.
For example, the data storage medium can be integrated into the
employee identification badge. A badge worn on the clothing or the
body can also be used for this purpose. The log-in takes place by
the person bringing the appropriate portable data storage medium
within the reception range of the reading unit, which is capable of
automatically reading it and then authorizing or refusing access to
the packaging machine. The transmission of information to be passed
by means of wireless and/or contactless means can occur in
different ways. For example, a bar code can be provided for this
purpose by using a scanner as the reading unit. It is also
possible, for example, to use a magnetic code. The data to be
transmitted consist, for example, of an employee ID number, a
suitable access code, a password or encryption of access rights. If
the data does not correspond to certain requirements, or if no data
are transferred, it is then impossible to log-in.
[0009] This type of log-in procedure also enables an especially
secure log-in, in which the effort required to gain access to the
packaging machine by an unauthorized person can be exceptionally or
prohibitively great.
[0010] An important saving of time results if the data storage
medium is integrated into the work clothing so that the data
storage medium is already automatically situated within the
reception range of the reading unit when that person assumes their
working position at the machine. It is also possible, for instance,
to locate the portable data storage medium in the belt, the
sleeves, or breast pocket, so that the person never needs to pay
attention to whether or if the data storage medium is positioned
close enough to the reading unit once he has assumed the suitable
work stance or position. In principle, any type of machine-readable
data storage media according to the invention can be used, such as
ultrasound transmitters and receivers, for example.
[0011] Insofar as a number of persons work simultaneously on a
packaging machine, it can also be desirable to choose an embodiment
of the invention in which the person to be logged-in must first
carry out an operation in order that the log-in process can be
carried out, before the reading unit is ready to receive the data
from the data storage medium. This can be implemented, for example,
by an input initiating a log-in program before the reading unit is
ready to receive the log-in data ("log-in prompt"). In particular,
this can prevent the situation where a person who is only working
in the vicinity of the packaging machine inadvertently logs-in or
enters his log-in information. The log-in process can thereby
remain an active process to be carried out intentionally.
[0012] A noteworthy feature of the invention is that it
simultaneously allows for a hygienic production process since the
log-in occurs in a contactless manner.
[0013] However, if circumstances occur that do not permit
logging-in through the reading unit, an alternative means of
registration still exists. In this connection it is advantageous
that access be enabled when problems, defects, or the like occur on
the machine. For example, access can still be available to service
personnel even if the reading unit and/or the data storage medium
is affected by a power outage.
[0014] In an advantageous embodiment of the invention, the
alternative input device is designed to be freely switchable. The
alternative input device is initially locked in this embodiment.
Non-expert operating personnel thus cannot access the alternative
application in the exceptional case mentioned above, e.g., in the
event of a defect or the like. Only expert personnel are able to
undertake the clearing process. This clearing process can, for
example, be carried out by means of a key, a bridge connection in
the region of the inputs or outputs of the control unit, or similar
measures.
[0015] The alternative input device could be manually operable, for
example, such as through the input of a numerical code, by means of
a key, or by a smart card that does not operate in a contactless
manner. If an appropriate defect is present, time can also be saved
by these measures even though service personnel still have a means
of accessing the packaging machine.
[0016] In a computer controlled packaging machine, an embodiment of
the invention can advantageously provide a means of logging-in from
inside a control program, so that servicing of the packaging
machine is not possible without previously logging-in.
[0017] It is especially advantageous to evaluate the transferred
information in a control unit, whether it comes from the reading
unit or from the bypass input device, which can relay appropriate
control commands to the machine controller, for example. Such a
control unit can also include an input device that permits not only
input of the information transferred from the data storage medium,
but also provides for input through control lines, for example. It
is also possible to make the control unit programmable.
Furthermore, it may be useful if the control unit can access other
data, whether it is machine-specific data or access rights, which
are assigned to a specific employee ID number. It is possible, for
example, that a log-in is no longer possible, or is possible only
under special conditions, when a malfunction of the machine has
been reported to the control unit. An advantageous embodiment of
the invention thus includes such a control unit.
[0018] A central control command that could be issued by the
control unit is the control of locking devices. A preferred
improvement of the invention includes at least one locking device
that is controllable by the control unit. For example, access to
the packaging machine is enabled or prevented by this locking
device. This can be implemented, for example, by opening or closing
a locking device. It is even possible to disconnect the packaging
machine as a hindrance to accessing the operation. It is also
possible in principle to route suitable warnings to a monitoring
terminal in the case of failed log-in procedures. The control unit
can consequently be designed in such a manner that it can execute
various functions, among others, in connection with the log-in
process.
[0019] Some data storage media allow writing of data on the data
storage medium along with the reading of permanently stored data.
Moreover, many data storage media must be activated, especially
when the data storage medium must be supplied with energy by
contactless or wireless means. Thus, in an advantageous improvement
of the invention a device for contactless or wireless energy supply
is present, which is integrated, for example, in the packaging
machine and/or is included with the reading unit.
[0020] Applications like writing data to the data storage medium
generally require that the data storage medium can be addressed by
means of electromagnetic waves. An embodiment of the invention is
distinguished by a transmitter unit being available to transmit
electromagnetic waves.
[0021] In this connection, an especially preferred improvement of
the invention envisions that the reading and/or transmitter unit is
designed as an RFID station (Radio Frequency IDentification).
Commercially available RFID transponder technology can be used with
corresponding cost savings. Under certain circumstances, both the
reading and transmitter units, as well as the RFID transponder, can
be purchased in the market as low-cost devices. RFID systems are
generally small, compact units for contactless identification and
also for locating objects. An electromagnetic high-frequency field,
whose fundamental frequency corresponds to the resonance frequency
of the oscillator circuit in the RFID transponder, is generally
transmitted from a reading unit. In order that the resonance
frequency in the oscillator circuit of the reading device is tuned
to the resonance frequency of the transponder oscillator circuit,
various modifications may thereby be necessary because of
transmission problems. For example, it can happen that the material
surrounding the transponder could alter the electromagnetic wave
slightly, thereby requiring slight tuning of the resonance
frequency of the oscillator circuit, such that it once again
matches the resonance frequency of the oscillator circuit in the
reading device.
[0022] In an embodiment of the invention, access to the packaging
machine can be permitted for the last successful log-in that was
carried out, while at the same time, access from a prior log-in
will result in refusal. Consequently, only the currently logged-in
person can work on the machine. In case the log-out procedure was
forgotten, or the packaging machine was turned off, this
carelessness can automatically be corrected by a new log-in.
[0023] Furthermore, hierarchically ranked access rights can be
assigned by the control unit during log-in with the aid of the
transmitted information. One possible classification of the extent
of access rights could, for example, depend on whether the log-in
is being made by operating personnel (low access rights), riggers
(medium access rights), or service personnel (global access
rights). Service personnel could furthermore be authorized for
access to a plurality of or all available packaging machines.
[0024] It could also remain subject to the service personnel to
obtain additional active access to the packaging machines if, at a
later time, a third party, e.g., with mid-range access rights
(operating personnel or riggers) attempts to log-in.
[0025] It is furthermore advantageous to design the control unit so
that following a specific time interval after log-in, access to the
packaging machine is refused, in principle to prevent logging-out
or shutting off. However, the access rights could also be reduced
to a minimum after the appropriate time interval, or modified in
general.
[0026] Security aspects play an increasingly important role. If a
numerical code must be input to check an access authorization, it
can be performed in principle by any person who knows the code. The
situation is different if biometric recognition is used. In a
special improvement to the invention, this kind of biometric data
can be read in through the reading unit and/or the alternative
input device, and used by the control unit to allow or block access
based on personal information.
[0027] Another embodiment of the invention offers a fundamentally
different possibility. It is often determined in retrospect that
irregularities or faults have occurred during the operating phase
of the machine. In this case it is desirable that operating
personnel attempt to carry out an efficient and effective fault
analysis. Such an assignment becomes difficult when a number of
persons potentially come into question for having carried out a
particular operational step on the packaging machine. Thus, an
advantageous embodiment of the invention includes a log-in device
that has at least one writeable memory unit that is controllable by
the control unit. This creates the possibility of recording a
transmitted employee ID number to a writeable medium, for example.
After the registration device has allowed access based on a valid
employee ID number and the control unit has, for example, unlocked
the locking mechanism, the control unit produces a write command
through which the employee ID number is recorded on a memory unit
with the corresponding start and end times of the operating
process. An individual-related attribution is thus made possible.
Likewise, it is possible to record other data and information in a
similar manner.
[0028] In particular, in production facilities that use at least
one packaging machine, monitoring terminals are installed to
centrally monitor the operation and functioning of the packaging
machines. Irregularities can thereby be determined quickly and
dealt with if necessary, even during operation. In addition to
monitoring, it can also be necessary, for example, to reprogram the
control unit and/or provide the memory unit with new data and
information. A preferred variant of the invention thus provides
that the control unit and/or memory unit of the packaging machine
be connected through an interface with an electronic network.
[0029] As has already been mentioned, it is possible to use a data
storage medium that is provided with a bar code. However, it is
advantageous if the data storage medium does not have to assume a
special orientation during the log-in process, which is the case
with the bar code for example. Thus, a preferred embodiment of the
invention provides a transmitter unit for wireless and/or
contactless data transmission. For example, the use of an
ultrasonic transmitter is possible. However, an electromagnetic
transmitter is generally cheaper and simpler to manufacture, and is
thus considered to be an especially preferred embodiment. In a
similar manner, a receiver unit for wireless and/or contactless
data transfer can be present on the data storage medium according
to an advantageous improvement of the invention. As already
mentioned above, this can be used to activate the data storage
medium or can even be used to transmit information to the data
storage medium.
[0030] An example of this type of activation is, in particular,
energy transmission from the outside, for example from the reading
unit to the data storage medium. A preferred improvement of the
invention provides that the data storage medium includes a device
that allows it to be supplied with energy from the outside. In
principle, for example, the packaging machine can likewise include
a device to enable this energy supply. The data storage medium thus
requires no separate energy source, such as a voltage source in the
form of batteries or accumulators, for example. Such batteries or
accumulators must be replaced after a certain amount of storage
time, or must be recharged.
[0031] It is possible in principle to provide a data storage medium
with its own voltage source, such as a battery or accumulator, for
example, in an embodiment of the invention.
[0032] The electromagnetic energy transmitted by the registration
device can, for example, be used by the data storage medium as the
energy source. According to an advantageous embodiment of the
invention, an induction coil and/or antenna is provided for energy
transmission between the reading unit and data storage medium.
However, if the energy is automatically transmitted as soon as the
data storage medium is used, another energy supply source is
unnecessary, and a savings in time and effort is thereby
achieved.
[0033] In order to design the data storage medium to be as compact
as possible, it is advantageous to combine the inductance and/or
antenna with the transmitter antenna. This embodiment of the
invention can be improved by the data storage medium being provided
with a RFID transponder unit. As has already been mentioned above,
this kind of transponder can be purchased very cheaply. In
addition, these systems and the RFID transponder in particular, can
be miniaturized to the point that the transponder can be integrated
almost completely and incorporated in an unobtrusive manner.
[0034] At the same time, a contactless or wireless energy supply
for the data storage medium by means of an RFID transponder in an
embodiment of the invention can be implemented cheaply and
efficiently.
[0035] In a preferred embodiment of the invention, particularly by
the use of an RFID transponder, an integrated switching circuit is
provided. By means of it, the data storage medium can also perform
additional functions, among other things. In an RFID transponder an
oscillator circuit is generally provided, which is coupled to such
an integrated switching circuit. Energy can likewise be received
through the oscillator circuit, which is used to supply the
integrated switching circuit.
[0036] In a preferred improvement of the invention the integrated
switching circuit is designed as a coding unit. If a memory unit is
present on the data storage medium for storing data, information
such as employee ID numbers, access rights, etc., then these data
must be coded and decoded in order to be converted into a
transmittable signal, or converted from a transmitted signal into
recordable data. In an RFID transponder, the oscillator circuit is
usually combined with such an integrated switching circuit that
more often than not provides the underlying function of a coding
unit.
[0037] A variety of possible designs can be used in this
connection. In an embodiment of the invention, the coding unit
includes at least one read-only memory unit for permanently storing
information. This is important, for example, when the employee ID
number or the like is to be recorded permanently on the data
storage medium. This can then be converted to a transmittable
signal by the coding unit before it is forwarded to the
registration device.
[0038] A read-only memory unit in the sense of the invention can be
implemented, for example, as a bar code. There are indeed many
other possible embodiments that also fall within the scope of the
invention, such as the use of electronic read-only memorys or other
such memory storage units that can only be erased by means of
special methods and then rewritten, such as, for example,
EPROMs.
[0039] In a manner similar to that already described, where the
registration device can advantageously include a memory unit, it is
also possible that the coding unit includes at least one writeable
memory unit with an associated writing unit that is controllable by
the coding unit. This embodiment of the invention is particularly
important when the data storage medium includes additional
functions and, for example, can be used for monitoring working
times. Depending on the organization of the means of production,
the data storage medium can thus also serve as the memory unit for
various purposes.
[0040] In principle, such data storage media can be used both for
the reading unit as well as for the alternative input device.
However, such a data storage medium is preferentially used for a
reading unit, and in particular for the reading unit.
EMBODIMENT
[0041] An embodiment of the invention is shown in the drawing, and
is explained in greater detail with the aid of the figures as
follows. They show:
[0042] FIG. 1 a schematic view of a packaging machine in operation,
and
[0043] FIG. 2 a schematic view of an information storage medium in
the form of an RFID transponder.
[0044] FIG. 1 shows a packaging machine 1 in which the base film 3
unwinds from a roll 2 and is guided on a conveyor section 19.
Packaging cavities 5 are formed from the base film 3 by means of
thermoforming equipment 4. They move along the conveyor 19 and are
filled with filling material 6 by personnel 7. The packaging
cavities 5 filled with the filling material 6 continue along the
conveyor 19, and are covered in a sealing unit 10 with a cover film
9 and sealed, and are finally trimmed by a cutting unit 31. The
cover film 9 is likewise unwound from a roll 8. The filled package
11 is a finished product of the packaging machine 1.
[0045] A mechanism 15 for controlling the packaging machine 1 is
likewise visible. This can be operated by the appropriate personnel
and/or programmers 17. Each of the personnel 7, 17 who work on the
machine respectively carries a data storage medium 12, 18. In
addition, log-in devices 13, 16 are provided at the respective
workstations. They are connected to a control unit 25 through data
lines 14. This control unit has a control line 26 leading to the
packaging machine.
[0046] Before the personnel 7 starts working at the packaging
machine 1, and thereby fills the corresponding packaging cavities 5
with the filling materials 6, a process for identifying the
personnel 7 must be carried out. For this purpose the data storage
medium 12, which is shown here as a badge or employee
identification card worn on the breast pocket, must be held in the
vicinity of the log-in device 13. It relays the appropriate
information over the data line 14 to a control unit 25. The control
unit 25 here is integrated within the control facility or terminal
15 of the packaging machine 1.
[0047] It is possible in principle to locate the log-in device 13
and/or the control unit 25 in the packaging machine, or to
integrate it, or deploy it separately.
[0048] Other personnel, such as a programmer 17 who could monitor
the troublefree operation of the packaging machine 1, or make a
change in the control program, such as altering the speed of the
conveyor, are correspondingly required to log-in at the control
terminal 15. This log-in process takes place by means of an
identification.
[0049] Any type of identification of the corresponding personnel 7,
17 can be carried out by means of an information storage medium 12,
18, while it is brought into the vicinity of the respective log-in
devices 13, 16. For example, the information storage medium 18 of
the programmer 17 is located in the vicinity of the hand. In this
case the data storage medium 18 is automatically located in the
vicinity of the log-in device 16 while operating the control
terminal 15. The log-in device 16 is also connected through a data
line 14 to the control unit 25 in this case. If a suitable
identification is not possible, then logging-in is prohibited, or
if this happens during the operation of the machine, for example,
an interruption signal is transmitted through the control line 26
to the packaging machine 1.
[0050] An alternative input device 32 is also provided for the
manual input of an access code using a keypad intended for access
by service personnel, for example.
[0051] FIG. 2 shows a data storage medium 18, which here includes
an RFID transponder 20. A coil 21 forming an oscillator circuit is
shown here with a capacitor 27. The voltage across the capacitor 27
is tapped, and part of it is cut off when the polarity changes by
means of a diode 28. In this manner a capacitor 29 can be charged,
which can serve as a voltage source to supply an integrated
circuit, for example, shown here as a coding unit 22. The coding
unit 22 includes a data memory unit 23 for read-only memory
storage, as well as a writeable memory unit with a recording unit
24.
[0052] An identification number is stored in an unalterable form,
for example, in the memory unit 23. Additional data, which is
either also transmitted, or received by the transponder 20 and
recorded there, could be recorded in the data memory 24 with the
integrated recording unit. These data could consist of, for
example, access rights or work schedules, as well as various other
types of information. The coil 21 is thereby designed as a
transmitter and receiver unit. In particular, energy can also be
received through the coil 21 in the form of electromagnetic waves
emitted from the log-in device. The oscillator circuit is thereby
adjusted so that its resonance frequency is tuned to the
fundamental radiated frequency.
[0053] A connection to the network is possible through an interface
by means of a suitable data line 30. The control unit 25 can thus
be monitored and controlled through another central monitoring
terminal.
[0054] All embodiments and improvements on the invention are
characterized such that at least one of the registration devices
(13, 16) includes: [0055] a reading unit for the reception of
information transferred in a wireless and/or contactless manner,
from a portable wireless or contactless readable data storage media
(12, 18), as well as [0056] an alternative input device for the
hard-wired input of information.
