Description

Werner Potrafke, Hattingen-Ruhr Eufeisenatraße 6 Stacking device for empty shopping baskets in self-service shops To increase the flow of sales in self-service stores, if you have already created cash booths around one vertical axis swiveling conveyor belt can bring the billed items to different collection compartments; if the dispatched customer is still busy packing his% arc, the next buyer can be served immediately afterwards and his shopping goods can be conveyed to another free compartment at the end of the checkout counter. Often, such cash desks are also combined with cash registers that are provided with active cash dispensing devices. In this way, it has been possible to largely accelerate work processes that represent a noticeable bottleneck in comparison with the rest of the work flow. However, at times of particularly high sales pressure, such a bottleneck still creates the problem of putting down the shopping baskets emptied of the goods. For example, the cashier was previously forced to bend down to the floor when placing the lower baskets of a stack to be erected, but after reaching a certain stack height, the aim of the innovation is to provide an effective remedy for this create and so. on the one hand to further relieve the cashier, on the other hand to make the sales activity even more efficient and fluid. With a device for stacking emptied shopping baskets < which occur at cash booths in self-service shops is According to the innovation along a vertical frame of about Kaaeenstandhöhe between an upper and lower limit position a platform can be moved under friction, which can occupy any height position between the two limit positions, but drops into the lower limit position after reaching a certain stacking load.

According to a particular embodiment, the platform is on the side attached to a carriage, which by means of castors longitudinally within the scaffolding vertically arranged rails can slide; a flexible traction device is attached to the carriage, which runs over a pulley rotatably mounted at the upper end of the frame and at the free end of which hangs a weight that moves up and down when the Move the platform up and down within a shaft formed by the scaffolding can.

When the platform has been emptied of the stacked shopping baskets, the resistance given by the friction of the sliding elements can be too small to prevent the platform from suddenly jumping up with certainty; Therefore, a damping device can be provided which reduces the speed of the platform when going up into the upper position to a permissible value. Such a damping device can be designed such that a linkage is pivotably attached to one side of the frame, which is connected to a damping element and whose free it engages in a funnel-shaped opening between the rollers of the carriage. Another feature of the innovation can be on the Platt a support plate can be placed loosely, which has the in the middle: A bare stacking area for the emptied shopping baskets provides us with the help of which the stack of baskets can be lifted off the platform and transported to the desired location. A particularly favorable embodiment of a stacking device according to the innovation results when the support plate is provided both with a handle that is conveniently accessible by hand, and with legs that extend laterally over the platform, at the lower end of which there are running wheels; the length of the legs is chosen so that the height of the support plate resting with its wheels on the floor is greater than that of the platform in its lower end position, so that the support plate is then easily pushed onto the platform or together with the one from the stacked empty shopping baskets existing stack can be pulled off.

An exemplary embodiment is shown below with reference to the drawing the innovation described. It shows.

1 shows a side view of the stacking device directly adjoining the checkout stand, FIG. 2 shows a vertical section through the frame of the stacking device according to the section line II-II in FIG. 3 with the damping device, FIG. 3 shows a plan view of the one in FIG. 1 stacking device shown. Adjacent to the task area 8 attached to the checkout stand 7 for the shopping baskets 9 filled with the individual articles is the frame 10 at about the height of the checkout stand for guiding the platform 11, which is within reach of the cashier, onto which the emptied shopping basket is placed 9 can be stacked. The platform 11 is in the middle attached to a support arm 12, the rear end of which is connected to a carriage 13 which can slide up and down by means of rollers 14 along the slide rails 15 arranged vertically within the frame 10. On the carriage 13 attack) a flexible traction means 16, z. B. a chain or a rope that runs over a deflecting pulley 17 rotatably mounted at the upper end of the frame and at the free end of which hangs a counterweight 18 in a shaft formed by the frame 10.

On a narrow side of the frame 10 can be pivoted about halfway up a linkage 19 is mounted, the free end of which with the opening 20 in the carriage 13 cooperates, which towards the side on which the linkage is located, with one funnel-shaped extension 21 is provided. The linkage 19 is in the vicinity of its storage point connected to a damping member 22 also attached to the frame 10, which may consist of a cylinder and a piston sliding in this.

By the action of the counterweight 18, the unloaded platform is brought into the upper end position. After a number of empty shopping baskets, such as three, have been stacked on the platform, the cashier at Ha has a downward pressure on the platform, thereby shifting it into such a position that the top of the already placed baskets is level det, in the eifte further number of baskets, in the assumed So case three, can be conveniently hung up, then it will the stack is pushed down again by the corresponding amount by the cashier. After about 15 baskets have been collected in this way, with a favorable altitude setting in between, the load on the platform is so great that it sinks under the influence of gravity into a lower bath layer.

With the help of a mobile frame sitting on the platform 23, the legs 24 of which are provided with running wheels 25 laterally over the platform and of such a length that the chassis after reaching the lower End position of the platform lifts from this and rests on the wheels 25, the entire stack of baskets are removed from the platform and transported to one place, where the baskets are to be available for reuse, e.g. B. to the entrance of the Self-service shop.

So that the platform remains at the desired height, is within the individual running organs or between the running surfaces of the movable ones Parts provided a certain sliding friction. She is so big that she connects with the action of the counterweight 16 is sufficient to u the platform 11 in each case to hold the set position as long as the load from the stacked baskets does not exceed a certain value.

Without special measures, the platform 11 located in the lower limit position and freed from the weight of the stacked baskets 9 would under certain circumstances suddenly return to the upper limit position and easily move to a forward position. Lead timely construction and installation, possibly also frighten or even scare customers in the vicinity endanger.
