Abstract

A method and an apparatus for the electronic recording of quantities on vending machines having suspension hooks are described. The basic object here is to make it possible in an operationally reliable way to record the articles hanging on the suspension hooks. For this purpose, provision is made for designing the suspension hooks (1) in electrical terms with measuring devices. Current measurement in the hook region is provided, the current flow through the suspension hook (1, 2) and through the electrically conductive tags (5, 5a) hung on the suspension hook (1, 2) being recorded. <IMAGE>

Description

The invention relates to a method and a Device for quantity detection on vending machines the preambles of claims 1 and 4.

Such devices are known per se, and also a procedure is used in which sales hooks in the rear tilt area, an electronic switch on point and here a weight determination of suspended Goods and products is carried out. So that Quantity of items hanging on the hook can be recorded.

Here, however, the disadvantage is that the up hanging area can be tilted downwards, with hangers can slip easily.

The object of the present invention is a Ver drive and a device of the type mentioned so white ter educate that in a reliable manner a Erfas solution of the items hanging on the hanging hook possible becomes.

To solve the problem, the features of the patent claims 1 and 4 provided.

It is essential here that a electrical measurement carried out even in the hanging area  while the device is attached to the special hook order.

Special designs of methods and devices result from the subclaims.

One embodiment of the method provides that a current measurement is provided in the hook area, the current flow through the hanging hook and through the electrically conductive on the hanging hook hanger is detected.

It is in a further training of the method provided that the products also with a hanger ger are provided, the hanger in the upper Be an electrically conductive path in the form a conductive area.

The design of the device provides that in the stream flow through the hanger arranged electrical elements are net, which encode the current flow.

In a further training, the electrical Elements as resistors, diodes or Zener diodes educated.

The current flow measurement on the hanging hook is one before partial DC measurement.

Further advantages are from the remaining claims can be seen, with features in the process an can be recorded.

The subject matter of the present invention provides not only from the subject of each patent  sayings, but also from the combination of the individual Claims among themselves. All in the records, one finally the summary, disclosed information and Features, in particular those shown in the drawings te spatial training are essential to the invention claimed, insofar as they are used individually or in combination are new compared to the state of the art.

In the following the invention is based on only one Execution path illustrating drawings explained in more detail. Here go from the drawings and their description further features and advantages of the He essential to the invention invention.

Figure 1 is a schematic arrangement of suspension hooks.

Figure 2 is a suspension hook with an electrically conductive gripping of the suspension hook by a suspension ger, where contact points a, b are shown in connection with the resistance of the suspension.

Fig. 3 shows a support wall with hanging hooks extending therefrom, for example parallel arrangement;

Figure 4 is an equivalent circuit diagram with respect to a hook on hook with a detection device of current and voltage.

Fig. 5 is a suspension hook in cross section with Customized rer embodiments with intermediate Isolie tion. 6 Touch points for the hanger are a and b.

In Fig. 1 is a sectional view, partly struck smiles, a product arrangement with a hanging hook 1 , 2 can be seen, wherein a product 9 is assigned to the hanging hook 1 . A product 10 , for example a food item, is arranged on the hanging hook 2 . Even with Le food a hanger 5 can be attached, which can also be assigned a product 9 as a hanger 5 a. The hanger 5 or 5 a has, according to FIG. 1, a conductive region 7 or 7 'in the hanger 5 according to FIG. 1. Such conductive areas 7 , 7 'represent an encompassing of the suspension hooks 1 and 2 , the suspension hook 2 having electrical insulation in the divided area 6 and insofar as points a, b on both sides, which represent 5 points of contact in connection with the hanger. A current flows over the point-like touches a, b. Further details are shown in FIG. 4.

From Fig. 4, a suspension hook 1 is shown in an exploded view as an equivalent circuit diagram, currents I1, I2 corresponding to the contact points a, b and a ', b' are shown.

Starting from a voltage U, a current can be measured in conjunction with a logic, which can be symbolized here in a DC measurement according to FIG. 4 with 2 hangers 1 , 2 as I = I1 + I2 (+ I _n ). It is important from an electrical point of view that a current flows from the contact points a to b.

The suspension hook 1 according to FIGS. 1-4 are elec tronically connected with an amount of detection which detects the number and type of hanger by a measurement in the electrically conductive hanger.

Furthermore, it can be provided that electrical elements are arranged in the current flow through a single hanger 5 , 5 a, which encode the current flow.

The electrical elements, e.g. B. in Fig. 4 additional Lich in the current flow through the contact points a or b or a 'or b' can be inserted z. B. additional resistors, diodes or tens diodes.

The electrical elements can be used as complex filters circuits are formed, the electrical inherent be measured with an impedance measurement, whereby additional currents flow in the suspension area, the z. B. can be indicated by an LED.
