Description

In the proposed dining room delivery device, the work of the cashier and the officers is carried out using an electric conveyor, in combination with several electric appliances. A conveyor from the kitchen passes through a number of tables. The client puts the coin of due value in the corresponding slot of the cash desk. The cashier box is located in front of each table on the wall of the conveyor case and shows the ordering person who is currently in the kitchen. The coin, the passage through the slot of the box office, signals in the kitchen a lunch box dispenser that requires, on which table and that the dish is paid for. The distributor, having seen the light-button button (on the shield in front of itself) that has burnt down, places the required dishes on the conveyor, on the {this button-button, {{the conveyor starts to move and the dish fits. To the waiting table. The window of the conveyor case opens and the customer takes

dinner.,

In FIG. 1 shows a circuit for switching on devices of a device; FIG. 2- a mechanism that opens the curtain in front of the customer's table at the moment of approach of the ordered dish; FIG. 3-shield placed in front of the kitchen dinner distributor; FIG. 4-box office, located in the dining room against each table; FIG. five-

key detail; FIG. b-key device and parts of the mechanism of FIG. 2; FIG. 7-- a general view of the transporting device (the left part of the figure, with part of the open conveyor and shield, is in the kitchen, and the right, with tables, is in the dining room).

The proposed device is equipped with a conveyor placed in a closed case (Fig. 7) and automatically activated by lowering the coin. In order to move the shutter 7, designed to open the casing when the dish approaches the customer, a spring cam 2 is applied. 7 (Fig. 1, 2, b, 7).

The lowering of the shutter 7 is carried out by means of pressing the latch b of the crank lever 7 with the puller 8 from the contact frame 9, which is replaced by the cam 2 after removing the dish (Fig. B).

In order to eliminate the names of dishes from the map, parts 70 on the name tape and electromagnets 77 in the circuit are applied to the switches 72 (Fig. 1).

The client, choosing a dish from the entire menu, which is on J3 (fig. 4), lowers the coin of the required value in

a slit next to the name of the selected dish. The coin goes through the cash slot (Fig. 5), the key / (Fig. 1) and closes the electromagnet circuit 15, when moving the core 16 of which closes the circuit of the button bulb 17. The bulb lights up on the shield} 8 (Fig. 3 and 7); it will be in the range of the required dish, and letting go, thus obtaining the requirement, puts on the conveyor (Fig. 7 and 1) my dish required, pressing the light Bulb button 17. From the specified press the light bulb 17 turns off, but together with By this, the key 19 closes the electromagnet circuit / 5, the measles 3 is attracted to the core of the electromagnet and, by means of the key 20, switches on the electromotor 21 connected to the conveyor. The conveyor is set in motion, the dish put on it goes to the table that requires it and, when it comes to, stops the cam 2 (Fig. 1) in its path hooking on the roller box 3, which is retracted and thus the electric motor turns off and, therefore, the conveyor stops. At the same time, as the dish approaches the site and cam 2 deflects measles 3, the latter doesn’t mean 4 (Figs. 1, 2 and 6). T ha, in turn, rests against the latch 6 t gi 22 through the cable 5 (Fig. 2), the block 23 and the lever 24 raises the shutter / (Fig. 2 dotted line, Fig. 7-3rd table) and the dish is open to the table and the order can be erot taken by moving from the conveyor to his table. Call 25, when the dish comes into place, calls about it until the delivered dish is removed from the conveyor. The bell chain closes with a 2o key (Fig. 1 and 6). The design of cam 2 is such that when it is lowered, i.e. when a dish is placed on it (Fig. 1), it enters the path of the roller box 5, abuts against the contact frame 27 (Fig. B), which inclines to frame / P; at the moment of movement of the core 3 to the core of the electromagnet 15, the cable 28 t does not have the frame 27 towards the frame 9, and thus contact is reached between them, the bell rings, and as soon as

the dish will be removed, the cam will be raised (springed) above the frame 27 and the bell chain will open, as the frame 27, released from the cam 2, opens with the frame 9 under the action of the spring (not shown). Subsequently, when the next dish is dispatched, cam 2 rests on the rrlik of frame 9 and, deflecting it, is no longer 5. Last time: pusher 7, fl he presses the cam 5 with his fist and releases the traction device 5 , 23, 24, the shutter 7 is lowered and the operation of the machine continues in the same order.

When it is required to exclude a dish that is sold out, such as soup, in the menu displayed in the dining room, then the distributor by turning the switch 12 (Fig. 3). hundred; the electromagnet // closes the electromagnet //, the shutter 29 moves as part 10 extends to the core of the electromagnet // and suffices, there is one hundred on the curtain against the window, replaced by no (Fig. 1 and 4) - /

The subject matter of the invention.
