Description

one

This invention relates to vehicle automation.

From the main auth. No. 4,08867, a device for vertical transporting and dispensing cylindrical articles is known, comprising a guide shaft, an elevator with load carrying strips and outgoing goods, tilted logs, with the slide in the dispensing area shifted relative to the elevator strips away from the discharge trays and opposite each tray in The recesses of the shaft wall are equipped with controlled rotary levers.

However, the known device does not provide for the loading of machine tools in small and equal portions of products, which leads to their downtime during accumulation by parts of discharge trays associated with subsequent machines.

In order to optimize the process of dispensing cylindrical products by providing alternate insertion of products into trays in separate portions, it is equipped with contact switches installed at the beginning and at the end of each tray, and normally closed

the contacts installed at the end and at the beginning of each tray are connected in series with the coil of the electromagnet connected to the cutter lever of this tray, and the normally closed contact of the switch installed at the end of each subsequent tray is connected in parallel with the group of normally open contacts of the switches installed at the end of all trays except the previous one.

FIG. 1 shows the device, a general view; in fig. 2 - given the basic electrical circuit of the device.

The device comprises a vertical guide shaft 1, an elevator 2 with load-carrying slats 3 and diverting inclined trays 4,

5 and 6. In the zone of issue, the longitudinal axis OOj of shaft 1 is shifted towards trays 4, 5, and 6. Swiveling locking hooks 7 are installed on the axes of each of trays 4 and 5 in the recesses of the wall of shaft 1 7. Against the upper tray

A cam 8 is installed in the shaft. The cut-off levers 7 are mechanically connected with electromagits 9 and 10 to control the turning of these levers.

, Trays 4 and 6 are connected to the machine using their iso-scramble parts AND, 12 and 13, and 14, 15 and 16, respectively. On some ra (x; that is, from the beginning and end of each curved 11, 12, and 13 trays 4, 5, and b, the contact switches 17, 18, 19, 20, 21, and 22 are installed to fill the trays, respectively.

For feeding the products in the device there is: a hopper 23 with a truck conveyor 24.

The switch 20 has a normally open contact 25 and a normally closed contact 26. The switch 21 has normally open contacts 27 and 28 and a normally closed contact 29. The switch 22 has normally open contacts 30 and 31. Catch 17 has normally closed contacts 32 and 33. The switch 18 has normally closed contacts 34 and 35. The switch 19 has a normally closed contact 36.

The coils of electromagnets 9 and 10 are included in an electrical circuit consisting of six parallel branches, having groups of normally open contacts 25, 27, 30 and 28, 3i of switches 20, 21 and 22 (circuits V and VI), as well as groups of normally closed kongakts 32, 34, 36, 26, 33 and 29, 35 of the pins 20, 21, 22, 17, 18 and 19 (chains II, I and V). Groups of normally closed contacts 26, EZ and 29, 35 of switches 20, 17 and 21, 18 are respectively connected in series with fcaiyiu, kami electromats 9 and 10 in trays 4 and 5 (circuit Iti and V). A normally closed contact 26 of the key 20 at the end of part 11 of the tray 4 is connected in parallel with a group of normally open, contacts 25, 27, 30 of the key. 20, 21, 22 at the ends of trays 4, 5 and 6 (tseg Ml-tV), and the normally zakshnuty contact 29 of the switch 21 is connected in parallel g, with a group of normally open 1, 1 and 28, 31 contacts of the switches 21, 22 at the ends of trays 5 and 6 (chain V-VI), i.e. without contact 25 of switch 20 at the end of the previous tray 4. Groups of normally open contacts 25, 27, 30 and 28, 31 of switches 20, 21 and 22 are connected in series to the corresponding coils of electromagnets 9 and 10 through normally closed contacts 33 and 35 of switches 17 and 18 At the beginning of elements 11 and 12 of trays 4 and 5 (circuit IV and circuit VI) To turn on the electric motor, there is a button 37 in the circuit connected in parallel to the contacts 38 of the automatic operation relay 39 (circuit T), as well as a magnetic starter 40 connected in series to kongak1gam 38 automatic relay bots and with each second normally closed contact 32, 34

and 36 sensors (circuit II) at the beginning of parts 11, 12, 1 of trays 4, 5, 6. To turn off the circuit, there is a button 41.

The device works as follows.

The control button is connected to the network. Using button 37 and normally open contacts in circuit I and circuit II (contacts 38), the automatic operation relay 39 and the magnetic starter 40 are activated, which

turns on the device motor. The electromagnets 9 and 10 are under voltage, so the slam-shut levers in tray 1 against tray 4 and 5 are turned and block the channel of the shaft. Izde.gsh from bunker 23 conveyor

24 are fed to an elevator 2, which moves them upwards along Schachta 1. Relying on the slats 3 and furthest from the chutes 4, 5 and 6 of the shaft, the product reaches the first cutter lever 7 against the chute 4 and rolls

In tray 4 and along its curved part 11 to the machine I. After laying at the end of the curved part 11 of the tray 4 servings of products, for example, three or four products, the sensor (switch) 20 is triggered, contact 26 of which opens the 1I circuit and turns off the electromagnet 9. And The sensor contact 25 in the iV circuit closes, the electromagnet 9 rotates the lever-cutter 7 and all subsequent lifted items pass by the tray 4, and, pushing onto the second cut-off lever 7, fall into the tray 5 and along its bent part 12 to the machine 15. After laying at the end of the curved portion of 12 portions and dely, nagfimer three or four fires sensor switch 21, konta1st

which 29 opens the circuit V and disconnects the electromagnet 10 (and the contacts 27, 28 of the sensor in chains IV and V are closed). As a result, the shut-off lever 7 is turned against tray 5 and all subsequent

the articles pass by tray 5 and, ng or 11, by cam 8, are delivered to the cam

part 13 to the machine 16. After laying at the end of the curved part 13 portions of products, for example, three-fours, the switch is triggered

22, closing the contacts 30 and 31 in the circuit iV and in the circuit VI. Earlier, in the same chains, the hgacts 25, 27, and 28 were closed by sensors 20 and 21. As a result, circuits IV and VI are closed, and electromagnets 9 and 10 are connected

to the network.

Further, the filling cycle of the flexible parts And, 12 and 13 of the trays 5, 6 and 7 is repeated by alternately operating the sensors 17, 18 at the beginning of the curved parts 11 and 12 of the trays.

5 and 6 and alternately connect pins 33 and 35 in chains V and VI. Pins 32 and 34, also in circuit 11, when the switches 17 and 18 open, open. When the switch is operated 19 at the beginning of the CURVED part

At the moment of its filling with contact 36, circuit 7 disconnects the M circuit, since previously contacts 32 and 34 were open in this circuit when the switches 17 and 18 were actuated. As a result, the drive is turned off by the magnetic actuator 40 (disconnected from the network in circuit 11). Raising and dispensing products ceases.

When the device operates at the moment of release of the switches 17, 18, 19, 20, 21 and 22, i.e. giving a signal about the absence of a product from it, the corresponding circuits are closed and opened, leading to the arrival of products into the tray on which the outgoing signal is fixed.

Thus, using the proposed device, the products are delivered in turn to the machines in the form of small pimples, and thus are prevented by the simple machines installed in the line.
