Vending machines, in particular cigarette machines

The invention relates to a goods vending machine, in particular cigarette vending machine, associated with provided in a housing shafts to stack have holding goods packs and a each shaft mechanical retrieval device which can be transferred after its release from a starting position into a removal position.

A large number of vending machines are purely mechanical formed and have no electrically controllable actuation and circuit parts, since this is a power supply to the existing voltage network would be required · However, there is a need in such vending machines to obtain a statement about specific data of the goods packaging.

The invention is therefore based on the object of selling goods To create sautomats of the type mentioned in a simple and functionally reliable manner while utilizing of existing parts from conventional vending machines A network-independent and energy-saving storage of specific data of the goods packages is to enable. the The control measures to be initiated by the extraction device of a manhole should be carried out using robust elements.

The object is achieved in that in the Machine housing a computer circuit arrangement with its own mains-independent supply battery for inclusion, Storage and reproduction of specific data of the goods packaging, in particular the shaft-related number of samples, it is provided that a switch arrangement which can be actuated by a permanent magnet is used as a signal transmitter for each shaft is provided that each time the removal device is moved into the removal position by changing the magnetic flux effect is closed, and that each switch assembly of a removal device or one Shaft has a coding level for generating a shaft-specific one Signal is assigned.

It is advantageous in every vending machine a low-power computer circuit arrangement with its own battery is provided. As a signal transmitter is for each shaft

a switch arrangement is available which is contactless due to magnetic flux effect of a permanent magnet can be actuated. When transferring the removal device from the Starting position in the removal position and vice versa the magnetic flux effect is controlled accordingly by the removal device, such that in the starting position located removal device, the switch assembly is open '. This makes one special robust switch arrangement has been created, which is independent of the environmental conditions, such as moisture and aggressive components of the surrounding atmosphere. The susceptibility of mechanical contacts to failure due to contamination is not given in the switch arrangement according to the invention. Furthermore, there is the advantage that this Switch arrangement does not require a power supply, as is the case with inductive scanners or optoelectronic scanners, for example Scanners or magnetic card reading devices is required.

According to a further embodiment, the switch arrangement has at least one reed contact, which together with the Permanent magnet housing is fixedly arranged, in the starting position of each removal device, preferably a drawer, a magnetically conductive shielding part of the removal device between the reed contact and the permanent magnet is moved, which is moved away when transferring the removal device into the removal position.

conducts, through which the disconnectable circuit parts are disconnected from the supply battery or in an inoperative Are switched to standby mode.

According to another embodiment, the delay effect of the processor-related control operations of the computer circuit educated. This has the advantage that the disconnectable circuit parts can be switched off during the opening movement of the unlocked drawer takes place. This in turn has the advantage that if the drawer is accidentally not closed (pulled out position) the disconnectable circuit parts are separated from the battery, and thus power consumption is kept low.

According to a further embodiment, the computer circuit has a time-of-day memory operating state, and when it is actuated of a second reed contact whose actuation time is stored, and when the first and second reed contact is actuated again, the time of the other Actuation phase is saved. This has the advantage that when the shaft is emptied, the refilling one Person can determine exactly when, for example, the last packaging unit was removed from the shaft. From this result particularly advantageous information about the location-specific requirements.

According to a further embodiment, lead from the computer circuit a data input and data output connection and a retrieval control line to a housing-side Connection point via which by means of an external data transfer device interrogated the memory data and the memory after re-entering the interrogated memory data in the computer circuit and if the memory data that have already been scanned match the memory data scanned again reset.
