Description
[0001] This application claims the priority of German Patent
Document No. 10 2004 043 102.7, filed Sep. 7, 2004, the disclosure
of which is incorporated by reference herein.
BACKGROUND AND SUMMARY OF THE INVENTION
[0002] The invention relates to a system for the unpacking of a
printing-paper roll. Furthermore, the invention relates to a method
for the unpacking of a printing-paper roll.
[0003] A web-shaped printing material which is kept ready in the
form of printing-paper rolls is printed on web-fed rotary presses.
The printing-paper rolls are stored in the packed state in a paper
store and have to be removed from the packaging before they are
introduced into a roll changer of the web-fed rotary press, and
accordingly unpacked. The procedure during unpacking of the
printing-paper rolls is that firstly what are known as the end
cover packagings are removed from the end sides of the
printing-paper roll, that next what is known as the circumferential
packaging is severed, and that subsequently the severed
circumferential packaging is removed from the printing-paper roll.
The removal of the end cover packagings, the severing of the
circumferential packaging and the removal of the circumferential
packaging take place in correspondingly adapted stations. Thus, for
example, EP 0 592 845 B1 shows a station for the removal of the end
cover packagings.
[0004] It is already known from the prior art to automate the work
sequences during unpacking of a printing-paper roll to a very large
extent, for example in the station for the removal of the end cover
packagings. However, a fully automated system or method for the
unpacking of a printing-paper roll has not previously been
disclosed in the prior art. Thus, according to the prior art, the
printing-paper roll has to be displaced manually into the
abovementioned stations, for example. Furthermore, a manual
severing of the circumferential packaging is also required
according to the prior art. Accordingly, a large number of manual
work steps are required according to the prior art in order to
unpack a printing-paper roll. The results of this are, firstly,
long unpacking times and that, secondly, the manual unpacking of
printing-paper rolls is expensive as a consequence of the use of
personnel.
[0005] Proceeding from this, the present invention is based on the
object of providing a novel system and a novel method for the
unpacking of a printing-paper roll.
[0006] The system according to the invention for the fully
automatic unpacking of a printing-paper roll comprises at least: a)
a station for the automatic removal of the end cover packagings
from a packed printing-paper roll; b) a station for the automatic
severing of the circumferential packaging on a printing-paper roll
with removed end cover packagings, the station for severing the
circumferential packaging adjoining the station for removing the
end cover packaging; c) a station for the automatic removal of the
circumferential packaging from a printing-paper roll having a
severed circumferential packaging, the station for the removal of
the circumferential packaging adjoining the station for the
severing of the circumferential packaging; d) a conveying device
which moves a packed printing-paper roll automatically into the
station for the removal of the end cover packaging, which conveying
device automatically moves a printing-paper roll, with the end
cover packaging removed therefrom, from the station for the removal
of the end cover packaging into the station for the severing of the
circumferential packaging, which conveying device automatically
moves a printing-paper roll having a severed circumferential
packaging from the station for the severing of the circumferential
packaging into the station for the removal of the circumferential
packaging, and which conveying device, furthermore, moves an
unpacked printing-paper roll automatically out of the station for
the removal of the circumferential packaging.
[0007] In terms of the present invention, a fully automated system
for the unpacking of a printing-paper roll is proposed for the
first time. In the system according to the invention, the station
for the automatic removal of the end cover packagings, the station
for the automatic severing of the circumferential packaging, and
the station for the automatic removal of the circumferential
packaging are connected to one another by a conveying device in
such a way that the printing-paper roll can be moved automatically
from one station to the next by the conveying device. All the work
steps in the stations are carried out in an automated manner and
subsequently without the use of personnel.
[0008] According to one advantageous development of the present
invention, the station for the automatic severing of the
circumferential packaging comprises a stationary severing device
which is positioned in the region of the conveying device, the
circumferential packaging being severed automatically by utilizing
the translatory relative movement between the moving printing-paper
roll and the severing device. Accordingly, it lies within the scope
of the present invention to use the movement, which is required in
any case, of the printing-paper roll from the station for the
removal of the end cover packagings into the station for the
removal of the circumferential packaging for the automatic severing
of the circumferential packaging. The results of this are, firstly,
particularly simple automated severing of the circumferential
packaging and that, secondly, the time is reduced considerably
which is required for the unpacking of the printing-paper roll.
[0009] According to a further advantageous development of the
present invention, the station for the automatic removal of the
circumferential packaging is assigned a delivery device for holding
and/or temporarily storing circumferential packagings which have
been wound up and thus removed from the printing roll. As a result,
it is possible to divide the actual removal of the circumferential
packaging from the printing-paper roll and the disposal of the
circumferential packaging into part sequences which are coordinated
with one another in temporal terms, as a result of which the time
which is required for the unpacking of a printing-paper roll can
again be shortened.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Preferred developments of the invention result from the
following description. Without being restricted thereto, exemplary
embodiments of the invention will be explained in greater detail
using the drawing, in which:
[0011] FIG. 1 shows a side view of a system according to the
invention for the unpacking of a printing-paper roll.
DETAILED DESCRIPTION OF THE DRAWINGS
[0012] In the following text, the present invention will be
described in greater detail with reference to FIG. 1.
[0013] FIG. 1 shows a diagrammatic illustration of a system
according to the invention for the fully automated unpacking of a
printing-paper roll. The system according to the invention
comprises a station 10 for the automatic removal of the end cover
packaging from a printing-paper roll, a station 11 for the
automatic severing of the circumferential packaging on a
printing-paper roll, and a station 12 for the automatic removal of
the severed circumferential packaging from the printing-paper roll.
A movement direction of the printing-paper roll through the
stations 10, 11 and 12 is shown in FIG. 1 by an arrow 13.
[0014] In terms of FIG. 1, the stations 10, 11 and 12 are connected
to one another by a conveying device 14. As can be gathered from
FIG. 1, a packed printing-paper roll 15 can be moved with the aid
of the conveying device 14 into the station 10 for the automatic
removal of the end cover packaging. In the station 10, the end
cover packagings at the two end sides 16 and 17 of the
printing-paper roll 15 are then removed automatically. A
printing-paper roll with end cover packagings which have been
removed from the end sides 16 and 17 is characterized by the
reference numeral 15'.
[0015] A printing-paper roll 15' with end cover packagings which
have been removed from it can then be moved by the conveying device
14 from the station 10 for the removal of the end cover packagings
into the station 11 for the severing of the circumferential
packaging. The circumferential packaging is then severed
automatically here.
[0016] After the automatic severing of the circumferential
packaging, the printing-paper roll having a severed circumferential
packaging can then be moved automatically by the conveying device
14 into the station 12 for the removal of the circumferential
packaging. The circumferential packaging is then removed
automatically in the station 12, a printing-paper roll with a
removed circumferential packaging being indicated by the reference
numeral 15''. The printing-paper roll 15'' with a removed
circumferential packaging can then be moved automatically out of
the station 12 for the removal of the circumferential packaging,
with the aid of the conveying device 14.
[0017] In terms of the present invention, it is accordingly
proposed to carry out all the work steps within the stations 10, 11
and 12 and the transporting or moving of the printing-paper roll
into the individual stations and out of them in an automated
manner. As a result, a fully automated system for the unpacking of
a printing-paper roll is provided.
[0018] The station 10 for the automatic removal of the end cover
packagings from a packed printing-paper roll 15 comprises, in the
region of both end sides 16 and 17, in each case one cutting device
18 and one holding device 19. For reasons of simpler illustration,
the cutting device 18 and the holding device 19 are shown only in
the region of the end side 17. For the automatic removal of the end
cover packagings, the cutting device 18 and the holding device 19
are moved into a defined relative position with respect to the
printing-paper roll in the region of each end side 16 and 17. Here,
the holding device 19 is preferably oriented with respect to the
printing-paper roll in such a way that the former is positioned in
the region of a central sleeve 20 of the printing-paper roll and
penetrates the end cover packaging in this region. The cutting
device 18 is preferably oriented relative to the printing-paper
roll at a radially outer end of the respective end side 16 and 17,
and introduced in this relative position into the end cover
packaging which is to be removed. With the holding device 19
introduced centrally into the end cover packaging and the cutting
device 18 introduced into the end cover packaging, the
printing-paper roll is then moved rotationally and thus in a manner
which rotates relative to the stationary holding device 19 and the
stationary cutting device 18. On account of this relative movement,
the cutting device 18 severs the end cover packaging at the
radially outer end in the circumferential direction, the holding
device 19 holding the severed end cover packaging automatically,
after a severing cut has been carried out along the complete
circumference of the end cover packaging, and moving the severed
end cover packaging out of the region of the station 10. In this
way, the end cover packagings can be removed from the
printing-paper roll simultaneously in the region of both end sides
16 and 17. It is to be pointed out that the holding devices 19' are
preferably configured as spreadable mandrels and the cutting
devices 18 are preferably configured as separating blades.
[0019] After both end cover packagings have been removed
automatically from the printing-paper roll in the region of the end
sides 16 and 17, the printing-paper roll with removed end cover
packagings is moved out of the station 10 for the removal of the
end cover packagings and moved into the region of the station 11
for the automatic severing of the circumferential packaging which
is still situated on the printing-paper roll. A severing device 21
is positioned in the region of the station 11 for the automatic
severing of the circumferential packaging, the severing device 21
being positioned in the region of the conveying device 14, namely
between two adjacent conveying sections 22 and 23 of the conveying
device 14. As can be gathered from FIG. 1, the two conveying
sections 22 and 23 are configured as belt conveyors which are
guided on deflection rollers 24. Here, the severing device 21 of
the station 11 is positioned between two adjacent deflection
rollers of the adjacent conveying sections 22 and 23. The severing
device 21 of the station 11 is configured as a stationary cutting
blade which uses the translatory relative movement of the
printing-paper roll during the movement of the latter out of the
station 10 to sever the circumferential packaging automatically.
During the movement of the printing-paper roll in the direction of
the arrow 13, it passes over the severing device 21 of the station
11, the severing device 21 automatically severing the
circumferential packaging on the underside of the printing-paper
roll in the process by using the translatory relative movement
between the printing-paper roll 15 and the stationary severing
device 21. Accordingly, the printing-paper roll is moved through
the station 11 in a translatory manner in order to sever the
circumferential packaging.
[0020] After the automated severing of the circumferential
packaging in the region of the station 11 by using the relative
movement of the printing-paper roll relative to the stationary
severing device 21, the printing-paper roll having a severed
circumferential packaging passes automatically into the region of
the station 12 for the automatic removal of the circumferential
packaging. In the region of the station 12, winding devices 25 are
positioned on both end sides 16 and 17 of the printing-paper roll,
the winding devices 25 gripping the severed circumferential
packaging at one free end in the region of the end sides 16 and 17
and then winding it up automatically. For the automatic winding-up,
the printing-paper roll is moved rotationally with respect to the
stationary winding devices 25, the winding devices 25 also rotating
in order in this way to wind up the circumferential packaging.
After the circumferential packaging has been wound up and thus
removed from the printing-paper roll, the wound-up circumferential
packaging is automatically moved by the winding devices 25 into the
region of a delivery device 26 which is assigned to the station 12.
In the region of the delivery device 26, wound circumferential
packagings 27 are deposited or stored temporarily. This means that
the winding devices 25 rapidly pass on the circumferential
packaging which has been removed from the printing-paper roll and
are thus available within a very short time for winding a new
circumferential packaging from a printing-paper roll which is
subsequently to be unpacked.
[0021] It lies within the scope of the present invention to use the
delivery device 26 not only for the temporary storage of wound-up
circumferential packagings 27, but rather also to compress the
wound circumferential packagings 27 in the region of the delivery
device 26 and to hold them together in the compressed state. For
this reason, devices (not shown) for the compression of wound-up
circumferential packagings and devices (not shown) for holding
wound-up and compressed circumferential packagings together are
integrated into the delivery device 26.
[0022] The devices for compressing are preferably configured as
pressing devices or squeezing devices. The devices for holding
together compressed circumferential packagings are preferably
configured as needle devices. By needle punching compressed
circumferential packagings, they are fixed in the compressed
position and a subsequent expansion in volume terms of compressed
circumferential packagings is avoided. In this way, the
wound-together circumferential packagings 27 can be stored
temporarily in the delivery device 26 in a space-saving manner.
Proceeding from the delivery device 26, the circumferential
packagings can then be fed to a further disposal means.
[0023] The present invention makes fully automated unpacking of
printing-paper rolls possible. The individual stations and the work
steps in the stations are coordinated with one another in such a
way that a printing-paper roll can be unpacked in a fully automated
manner within a very short time. The result is high efficiency when
printing-paper rolls are unpacked.
