Description

Technical Field

[0001] The utility model relates to a counting system for selling cigarettes, in particular to a counting structure for a cigarette pusher. Background Art

[0002] In the traditional retail industry, small commodities such as cigarettes are usually displayed on shelves and manually replenished by store clerks to maintain the number of products on the shelves. However, although existing cigarette pushers can push cigarette boxes (boxes filled with cigarettes), they have many shortcomings in inventory management, such as the real-time display of the number of cigarettes sold in the cigarette pusher. Existing technology is difficult to meet the needs of modern retail management.

[0003] Completely replacing existing cigarette vending machines is costly, especially in large-scale retail malls and convenience stores. Therefore, there is an urgent need for a counter that can adjust the structure of existing cigarette pushers to record the number of cigarette packs sold in real time, without replacing existing cigarette vending machines.

[0004] At present, a "new type of cigarette pusher" with publication number CN216970822U has been retrieved. The new type of cigarette pusher includes a storage box, a cigarette bin, a vertical push plate, a metal spring sheet, and a press buckle. The storage box includes a box body, a dovetail block, a dovetail groove, a snap-fitting protrusion, and a horizontal rib. The dovetail block is arranged on the left outer surface of the box body, the dovetail groove is arranged on the right outer surface of the box body, the snap-fitting protrusion is fixedly connected to the inner surface of the left end of the box body, and the horizontal ribs are horizontally arranged on the inner surfaces of both sides of the box body. The cigarette bin can be fixed to the cigarette bin inside the storage box by pressing the buckle, and the storage box can fix the cigarette bin in the cigarette pusher. Although the stability of the cigarette pusher in taking and placing cigarette boxes is improved, the storage boxes can be fixed to each other so that they can be fixed in a row above the shelf. The press buckle provided can fix the cigarette pusher, which is convenient for the operator to take and place; but the cigarette pusher cannot realize real-time recording of the number of cigarette sales boxes.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] The cigarette pusher counting structure of the present invention includes a cigarette pusher housing 1 and a push plate 2 slidably connected to the cigarette pusher housing 1, a coil spring 3 is provided at the back of the push plate 2 (the coil spring 3 can also be a clockwork, the center end of which is fixed, the free end can be pulled, and has a tendency to retract when the free end is pulled), and a cover 13 for covering and installing the coil spring is fixedly installed on the back of the push plate 2, and a channel is provided on the cover and the push plate to facilitate the passage of the coil spring leaf.

[0027] The free end of the coil spring 3 passes through the channel and is fixedly connected to the front wall panel 4 of the cigarette pusher housing, forming a storage space 5 for inserting a cigarette box between the push plate 2 and the front wall panel 4. The cover 13 and the push plate 2 can be fixed to form a whole. The coil spring 3 has a contraction force so that the push plate tends to approach the front wall panel.

[0028] A rear shell body A1 and a vertical plate A2 parallel to the push plate are provided at the rear of the cigarette pusher housing 1. The vertical plate A2 may be a part of the rear shell body A1. A laser infrared ranging sensor A3 facing the push plate is fixedly mounted on the vertical plate. A controller A4 electrically connected to the laser infrared ranging sensor and a power module A5 are provided in the rear shell body A1. A display module A6 electrically connected to the controller is provided on the cigarette pusher housing 1 (the display module A6 may be a display screen, which is preferably fixedly mounted on the front wall panel 4). The controller A4 and the power module A5 are specifically mounted on a PCB circuit board A7. The controller A4 receives the laser infrared ranging sensor The distance data measured by sensor A3, namely the real-time distance S between the laser infrared ranging sensor and the push plate, is converted by the controller to obtain the number N of cigarette packs reduced in the storage space (i.e., sales volume), where N = (DS) / d, D is the distance between the laser infrared ranging sensor and the push plate when the storage space is full of cigarette packs, and d is the thickness of the cigarette packs. The circuit connection and conversion of the controller are conventional technologies and are not described in detail here. The value obtained by the controller conversion is the cigarette sales count, which is displayed by the display module to achieve the first set of counts. If the data does not return to zero within a month, the monthly sales volume is displayed.

[0029] In order to achieve double detection of sales volume, the rear part of the cigarette pusher shell is provided with a power shaft 6 (the circumference of the power shaft is equivalent to the thickness of the cigarette box) parallel to the front wall panel and the push plate. The two ends of the power shaft 6 are rotatably connected to the rear shell A1 through bearings. A first rope 7 is wound counterclockwise on the power shaft 6. The first end of the first rope is fixed on the power shaft, and the second end of the first rope is fixed on the push plate 2. Under the pulling action of the coil spring, the push plate 2 is close to the front wall panel, and the power shaft also has a counterclockwise rotation tendency; a motor A8 and a second rope 9 wound on the output end of the motor are provided in the rear shell. The free end of the second rope is connected to the power shaft 6. Under the rotation and pulling action of the output end of the motor, the power shaft has a clockwise rotation tendency, that is, the first rope and the second rope pull the power shaft to rotate in opposite directions. The motor starts to work, realizes the winding of the wound second rope, drives the power shaft to rotate clockwise, and then winds and pulls the first rope on the power shaft.

[0030] A sliding sleeve 10 is mounted on the power shaft and can rotate synchronously with the power shaft. A button 12 and a counter 11 triggered by the button are provided on the PCB circuit board (the counter can be a commercially available push-type electronic counter, and the button 12 is the button on the push-type electronic counter). When the power shaft rotates, the sliding sleeve is synchronously driven to rotate and the button is toggled to realize the counting of the counter. Every time the power shaft rotates one circle, the sliding sleeve 10 triggers the button 12 once, and the counter 11 counts once to realize the second set of counting. By comparing the two sets of counts, it is possible to avoid a failure of one calculation mechanism to count due to a malfunction.

[0031] Specifically, a plurality of through holes are provided on the power shaft. The first end of the first rope 7 is first bound to the first through hole 14, and the second end of the second rope 9 is first bound to the second through hole 15. Then the first rope 7 is wound on the power shaft counterclockwise, and the second rope 9 is wound on the power shaft clockwise.

[0032] The above-mentioned power shaft is provided with a first shoulder 16 on both sides of the first through-hole, and the winding position of the first rope is limited within the range of the two first shoulders; the power shaft is provided with a second shoulder 17 on both sides of the second through-hole, and the winding position of the second rope is limited within the range of the two second shoulders. The first shoulder 16, the second shoulder 17 and the power shaft are formed as one piece.

[0033] The above-mentioned cords (the first cord 7 and the second cord 9 ) may be inextensible nylon cords or steel cords.

[0034] The power shaft is provided with an axially extending guide groove 18. The sliding sleeve (a circular sleeve) is slidably connected to the axial direction of the power shaft. A key 19 is provided on the inner circumferential wall of the sliding sleeve 10, which engages with the guide groove 18, ensuring synchronous rotation of the sliding sleeve when the power shaft rotates. A groove 20 is provided on the first shoulder 16, corresponding to the guide groove 18. The sliding sleeve is provided with a pressure strip 21 that fits into the groove. When the sliding sleeve slides axially along the power shaft (manually operated by a salesperson), the sliding sleeve or its pressure strip can be brought into or out of contact with the button 12 of the counter 11. When in contact, the sliding sleeve rotates synchronously with the power shaft (i.e., during normal use). When out of contact (i.e., during restocking, when the cigarettes in the storage space 5 are completely sold out and new cigarettes are added), the button 12 is not pressed when the sliding sleeve rotates synchronously with the power shaft.

[0035] How the second set of counts works:

[0036] When no cigarette box (new, unopened boxed cigarettes) is stuffed into the cigarette pusher, the push plate approaches the front wall panel of the cigarette pusher housing under the pull of the coil spring. When the cigarette pusher is stuffed with cigarette boxes, the push plate is pushed away from the front wall panel. At this time, the push plate has a tendency to move toward the front wall panel under the action of the coil spring. When a cigarette box is taken out of the cigarette pusher, the push plate approaches the front wall panel by the thickness of a cigarette box. Since a first wire rope is wound counterclockwise on the power shaft, a first end of the first wire rope is fixed on the power shaft, a second end of the first wire rope is fixed on the push plate, and an output end of the motor is wound around the first end of the second wire rope. The free end of the second string is connected to the power shaft (the second string is wound around the power shaft in a clockwise direction). Under the pulling action of the motor, the power shaft has a clockwise rotation tendency. Therefore, when a cigarette box is taken out from the cigarette pusher, the push plate is close to the front wall panel by the thickness of a cigarette box, and the first string pulls the power shaft to rotate one circle clockwise (the circumference of the power shaft is equivalent to the thickness of the cigarette box), causing the pressure strip on the slide to press the button 12 once, so that the push-type counter counts once, that is, each time a cigarette box is taken out, the push-type counter counts once. Therefore, the number of cigarette boxes sold can be recorded in real time.

[0037] After all the cigarettes in the cigarette pusher have been taken out (i.e., completely sold), the slide is moved axially along the power shaft so that the pressure strip on the slide does not contact the button 12 of the push-type counter. Only then are cigarettes inserted into the cigarette pusher, and then the slide is pushed axially along the power shaft again so that the slide contacts the button 12, so that the button 12 of the push-type counter can be pressed to generate a count when the slide rotates.

[0038] The counting structure of the cigarette pusher of the present invention is reasonably designed. It can realize real-time recording of the number of cigarette sales boxes through the first group of counting and the second group of counting. The two groups of counting can be compared to avoid large discrepancies in data due to failure of a certain group of components, which makes it convenient for sales personnel to know the sales volume. When the counter does not return to zero within a certain period of time, such as within a month, the sales volume of a month can be counted, that is, the statistics of monthly cigarette sales volume are realized.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are welcome.
