Description
The present invention concerns a device for self-service stores for
use in connection with shopping baskets or shopping carts, which
device comprises primarily a cash register stand, a deposit station
for the filled shopping baskets or a check-out plate for an
intermediate depositing of the goods when shopping carts are
employed, and furthermore comprises primarily three withdrawal
compartments for the withdrawal of the checked-out goods.
Cash register tables and devices of the above mentioned type are
known in various forms. These devices are normally equipped with
two or more withdrawal compartments. Experience and tests have
shown that a cash register stand with three withdrawal compartments
is more economical than a cash register stand with two withdrawal
compartments. For a fast servicing of the customers during rush
hours, especially over the week end, cash register tables with
three withdrawal compartments are a must. It is the tendency in
self-service stores to reduce the number of cash register stands or
tables and to increase the economy of each individual cash register
stand or table.
A modern cash register table is expected to have as large
withdrawal compartments as possible so that an individual
withdrawal compartment will be able to accommodate a considerably
greater assortment of goods bought over the week end. An increase
in surface of the withdrawal compartments, however, is counter to
the requirement to reduce the space of a cash register table to a
minimum in order to save floor space. To meet the above mentioned
requirements which are directly counter to each other, represents a
rather difficult and important problem. With heretofore known
customary cash register tables comprising three withdrawal
compartments, the above mentioned requirements are hardly met or
are met only insufficiently.
In addition to considering the above outlined requirements, a cash
register table also has to take into consideration the physical
stress to which the cashier is subjected. Also in this respect many
of the heretofore known cash register tables are insufficient. In
spite of the employment of mechanical conveying means, such as
conveyor belts, with various cash register tables, relatively long
conveying paths are necessary which have to be bridged by the
manual action of the cashier.
According to a previous suggestion for a device to be used in
self-service stores, the distance between the withdrawal of the
goods by the cashier during the check-out operation and the three
withdrawal compartments has been reduced to a minimum by a novel
way of dividing the respectively available surface. When shopping
baskets are employed, the withdrawal of the goods is effected at
the place where the shopping baskets are deposited whereas, when
employing shopping carts, the withdrawal place is formed by a
check-out plate at the end of the conveyor belt and in this
instance is located directly in front of the inclined surface
leading into the withdrawal compartments and, more specifically, is
located in the center of the device, i. e. in front of the central
withdrawal compartments.
It is an object of the present invention with a device of the above
mentioned type to improve the transfer of the checked-out goods to
the individual withdrawal compartments.
It is another object of this invention so to improve the transfer
of the checked-out goods to the withdrawal compartments that the
work of the cashier is simplified and that also the construction
and the costs of the device are simplified and reduced while
simultaneously the withdrawal compartments are increased as to
their capacity while the total surface of the device is not
increased.
These and other objects and advantages of the invention will appear
more clearly from the following specification in connection with
the accompanying drawings, in which:
FIG. 1 diagrammatically illustrates a top view of a device
according to the invention for use in connection with shopping
carts, said device including a conveyor belt in the form of a metal
or link conveyor belt.
FIG. 2 is a section taken along the line II -- II of FIG. 1.
FIG. 3 diagrammatically illustrates a top view of a device
according to the invention for use in connection with shipping
baskets, said device likewise comprising a metal or link conveyor
belt.
FIG. 4 is a diagrammatic end view of the withdrawal compartments of
a device according to the invention with two conveyor belts adapted
to be folded upwardly.
FIG. 5 is a view similar to that of FIG. 4 with the left-hand
conveyor belt folded downwardly into its working position.
FIG. 6 is a section taken along the line VI--VI of FIG. 5.
FIG. 7 represents a diagrammatic partial view of a conveyor belt
adapted to be folded upwardly, in which the pivot axis is located
below the inclined surface.
FIG. 8 is a diagrammatic top view of that portion of the device
which comprises the withdrawal compartments and comprises a
rotatably mounted conveyor belt.
FIG. 9 is an illustration similar to that of FIG. 8 in which the
conveyor belt has been turned into its rest position.
The device according to the present invention is characterized
primarily in that at the upper end of the inclined surface in front
of the central withdrawal compartment there is provided a conveyor
belt which extends over the width of the central withdrawal
compartment and is in the form of an endless metal band or a link
band with conveying means which extend transverse to the
longitudinal axis of the device and is adapted to be folded
upwardly or to be turned. When loading the central withdrawal
compartment, the conveyor belt is at a standstill and in folded-up
position serves as slide or chute.
According to a further development of the invention, at that side
of the conveyor belt which faces the withdrawal compartments, there
may be provided a foldable strip adapted to be folded into the
plane of the belt. Such strip is particularly advantageous when the
conveyor belt in its folded-up position occupies a horizontal
position.
According to still a further development of the invention, the
conveyor belt forms together with the drive motor a unit which is
foldable as a unit.
The control of the drive motor may, according to the present
invention, be so designed that when folding the conveyor belt
downwardly, the circuit for the drive motor is interrupted by a
limit switch. The limit switch may be effective in the lower
position as well as in the upper position. This design is
structurally particularly simple because only a single conveyor
belt is necessary the foldable mounting of which will cause no
manufacturing difficulties whatsoever. If for serving the
costomers, only two withdrawal compartments are necessary, the
conveyor belt remains in its upwardly folded position and is
shifted by the cashier only in conformity with the respective
desired conveying direction.
Instead of a conveyor belt which, when the drive motor is at a
standstill, forms the sliding surface or chute for loading the
central withdrawal compartment, there may also be employed a design
according to which one or two conveyor belts in the form of a web
belt may be employed merely for loading the central withdrawal
compartments, whereas when loading the central withdrawal
compartment, the belt or bands are folded upwardly or toward the
side so that the goods will over the inclined surface pass into the
central withdrawal compartment.
An embodiment intended for this way of operation is according to
the invention characterized primarily in that at the start of the
inclined surface at least one endless conveyor belt, the length of
which corresponds to the width of a withdrawal compartment, and
which has a strip on that side which faces the withdrawal
compartments, is foldably arranged in such a way that the endless
conveyor belt is adapted to be folded from a position substantially
parallel to the inclined surface and located along an extension of
the check-out plate into a position substantially perpendicular to
the inclined surface so that the conveyor belt will be located
approximately along an extension of the two partitions between the
withdrawal compartments.
Instead of a single conveyor belt reversible as to its conveying
direction, also two upwardly foldable conveyor belts with fixed
conveying direction may be provided, the arrangement being such
that each of the two conveyor belts will, when in folded-up
condition, be located along an extension of a partition.
In order to secure the conveyor belts in their upwardly folded
position against any unintentional downward folding, counter
weights or springs may be connected to the conveyor belts which
load themselves during a tilting movement from the rest position to
the working position.
According to a further development of the invention, that side of
the conveyor belt which faces away from the withdrawal compartments
may be provided with a running-up plate which bridges the gap
between the end of the check-out plate and the conveyor belt.
For purposes of reducing the height of the upwardly folded conveyor
belt, the pivot axis of the conveyor belt may, according to the
invention, be located either between the reversing rollers of the
belt or below the inclined surface.
According to still another embodiment of the invention, only a
single conveyor belt is provided which is reversible as to its
conveying direction and the length of which corresponds about to
the width of the central withdrawal compartment. This single
conveyor belt is rotatably journalled at the start of the inclined
surface in such a way that it is turnable by 90.degree. from a
position transverse to and in front of the central withdrawal
compartment and parallel to the plane of the inclined surface into
a position representing approximately a central extension of one of
the two partitions. With this embodiment, the axis of rotation of
the conveyor belt is located outside the reversing rollers.
All of the various above outlined embodiments of a device for
self-service stores have the advantage that for conveying the
checked-out goods to the individual withdrawal compartments, only a
very short transporting length is necessary for loading all three
compartments while the transporting length is approximately the
same for each of the three compartments. This transporting length
or path will, with a design employing shopping carts, correspond to
the displacement of the goods from the check-out plate to the
conveyor belt located therebehind or to the inclined surface, and
with a device for use in connection with shopping baskets,
correspond to the distance between the depositing station for the
baskets and the conveyor belt adjacent thereto or the inclined
surface. The cashier will thus be considerably relieved as to
physical work. In addition thereto, the transporting or conveying
of the goods to the withdrawal compartments offers a reduction in
the space required for the distribution of the goods and thus
offers the possibility of increasing the volume of the withdrawal
compartments by extending the partitions while the base surface of
the device is retained.
Referring now to the drawings in detail, the device shown therein
has a rectangular basic contour and comprises primarily a cash
register stand 1, a space 2 for the cashier 3, a conveyor belt 4
with adjacent check-out plate 5, a place 6 for a helper 7, and
adjacent an inclined surface 8 three withdrawal compartments 9, 10
and 11 located adjacent to each other. In front of the withdrawal
compartments there is provided a board 12 for depositing a shopping
bag. The withdrawal compartments are separated from each other by
partitions 13, 14.
At the start of the inclined surface 8 and in a corresponding
cutout there is located an endless conveyor belt 15 in the form of
a metal or link band which is arranged in front of the central
withdrawal compartment 10. This conveyor belt 15 is foldable
upwardly from its position in the plane of the inclined surface 8
about a shaft 16 into a horizontal or slightly lifted position as
shown in FIG. 2. On the bottom side of the conveyor belt 15 there
is provided a protective sheet 17 which, when occupying its
upwardly folded position, will cover the cutout in the inclined
surface. The protective sheet 17 extends also along the narrow
sides of the conveyor belt. The non-illustrated drive motor is
together with the conveyor belt expediently connected so as to form
a unit so that the conveyor belt and the motor are foldable
upwardly together or as a unit.
For turning the drive motor on and off, a limit switch may be
provided which may be actuated either when the conveyor belt has
reached its lower or upper position. The reversing of the direction
of rotation of the motor is effected by a manually or foot operable
reversing contact. For additionally guiding the goods, one or both
of the longitudinal sides of the conveyor belt may be equipped with
strips. The strip located on that side which faces toward the
withdrawal compartments may be so designed that in folded-down
position of the conveyor belt it is adapted to be shifted inwardly
or to be pushed inwardly.
The operation of this device is as follows: When loading the two
outer withdrawal compartments 9 and 10, the conveyor belt 15 will,
as evident from FIG. 2, occupy the upwardly folded position. The
goods to be checked-out pass via conveyor belt 4 to the check-out
plate 5 from where they are passed by the cashier simultaneously
with the check-out operation at the cash register stand to the
conveyor belt 15. Depending on the direction of conveyance of the
conveyor belt, the goods pass into one or the other withdrawal
compartment.
When it is desired to load the central withdrawal compartment 10,
the conveyor belt 15 is folded downwardly while at the same time
the circuit for the drive motor is interrupted. The goods are now
able, over the surface of the metal or link belt serving as slide
or chute, to slide into the central withdrawal compartment 10.
The embodiment of FIG. 3 differs from the embodiments of FIGS. 1
and 2 merely with regard to that part which is located in front of
the inclined surface and which instead of a conveyor belt comprises
a depositing station for the shopping baskets 18. This part
likewise comprises a cashier's stand 19, a seat 20 for the cashier
21 and a space 20 for a helper 23.
According to the embodiment of FIGS. 4 to 7, two vertically
upwardly foldable conveyor belts 25, 26 are provided, said conveyor
belts being foldable upwardly relative to the inclined surface 24.
The drive 27, 28 is located below the inclined surface 24. On that
side which faces the withdrawal compartments, there is each
provided a strip 29, 30 which is located on the conveyor belt.
Furthermore, a counter weight 31, 32 is connected to each conveyor
belt which counter weight serves for stabilizing the upwardly
folded position.
For purposes of bridging the distance between the check-out plate
33 and the conveyor belt 25, there is provided a running-up plate
34 as shown in FIG. 6. This plate is fixedly connected to the
conveyor belt.
According to the embodiment of FIGS. 4 to 6, the pivot axis 35, 36
of the conveyor belt is located above the inclined surface. It
coincides with the axis of rotation of one of the two reversing
rollers so that the drive does not have to be moved when folding
the conveyor belt upwardly or downwardly.
The pivot axis may, as indicated in FIG. 7, also be located between
the two reversing rollers at 37. In such an instance, in the
upwardly folded position, the height of the conveyor belt is
reduced relative to the inclined surface 24. However, if desired,
the pivot axis may also be located at 38 outside the conveyor
belt.
The operation of this embodiment is as follows: When loading the
central withdrawal compartment, both conveyor belts 25 and 26 are
folded upwardly as shown in FIG. 4. If, however, one of the two
outer withdrawal compartments is to be loaded, one or the other
conveyor belt is to be folded downwardly. The respective upwardly
folded conveyor belt serves as extension of the partition and
prevents the goods from moving into the non-intended withdrawal
compartment.
According to the embodiment of FIGS. 8 and 9, the conveyor belt is
rotatable about an axis 40 in the plane parallel to the inclined
surface. For purposes of laterally guiding the goods, this
embodiment comprises a strip 41 which is located on that
longitudinal side of the conveyor belt which faces the withdrawal
compartments. Instead of a single rotatable conveyor belt, also two
conveyor belts may be provided each of which in such an instance
circulated in one direction but opposite to the direction of
movement of the other conveyor belt.
The operation of the device of this embodiment corresponds
substantially to the operation of the device of the first
embodiment with the only difference that for loading the central
withdrawal compartment, the conveyor belt has to be turned into the
position shown in FIG. 9.
It is, of course, to be understood that the present invention is,
by no means, limited to the particular embodiments shown in the
drawings but also comprises any modifications within the scope of
the appended claims.
