Description

Vending machines are known for piece goods, in the case of which there are several rows of shelf sections, which are closed by transparent doors. By means of a push-button device acting on the lever mechanisms, the flaps open when the coin is lowered.

The proposed vending machine differs from those known in that, in order to ensure the opening of only one section, the sash frame is provided with a plate with a hole and an arcuate slot, which includes the spring-loaded measles of the electromagnet activated by the button. The edge of the plate with a closed flap interacts with the contacts of the electric lock.

In order to conveniently repair the damage to the button and adjust its contacts, the button and its contact group are mounted on the frame using a stripping plate.

FIG. 1 shows an external view of the vending machine; in fig. 2- lock with the shutter closed, side view; in fig. 3 - the same, with the open flap; in fig. 4 shows a section along A-A in FIG. 2; in fig. 5 - cut across BB to fit. 3; in fig. 6 is an electrical interlock circuit.

In the case of the vending machine, there are shelf sections located in several rows one above the other, each of which is covered by a transparent pivoting flap /. Each flap has a reinforced plate 2, having an opening 5 and an arcuate slot 4, and on the frame 5 of the automaton, an electromagnet 6 is mounted perpendicular to the plate 2, the measles 7 of which is equipped with a spring 8. The plate 2 interacts with its upper edge with contact group 9.

On the frame 5 of each section, button 0 is mounted, placed in the sleeve / 7. The latter is connected to detachable plate / 2, on which contact groups 13 and 14 are fixed. Such an arrangement allows

It is easy to remove from the frame for repair and adjustment both the button with the sleeve and the plate with contact groups. The electrical circuit also includes contacts 15, 16, 17 and 18, relay 19 and electromagnet 20.

As a result of the coin being lowered into the slot 21, the contact 15 is short-circuited. This triggers the relay 19, which closes the contact 17, - supplying positive current to the contact groups 13; at the same time, the negative current is supplied to the contact groups 14. When one of the buttons 10 is pressed, the left contacts in the 13 W groups open. 14 and the right contacts close. In this case, the current passes through the electromagnet 6 and pulls in the measles 7, which comes out of the hole 5 in the plate 2, and the flap / opens. All other buttons 10 are de-energized.

When opening the sash / plate 2 short-circuits the contact group 5; The electromagnet 20 opens contact 16. The electric current circuit, in which relay 19 is turned on, is broken, as a result of which contact 17 is opened. When closing the sash / measur 7 under the action of the spring 8 enters the aperture 3 of the plate 2, locks the sash. The machine is provided with a lock, upon opening of which the contact 18 closes, supplying current to the contact groups 13 and 14. Thus, all the flaps can be opened without lowering the coin, for example, when filling sections with goods.
