Description

one

The invention relates to industrial transport, in particular to machines for stacking and single-piece delivery of products.

A known machine for stacking and single-piece delivery of products, containing devices for stacking and single-piece delivery, interconnected by means of a conveyor belt with a transfer body

1 However, this machine does not provide for any additional organ, allowing the youth to compensate for the non-synchronous operation of the devices, which, in pelts, reduces the reliability of the machine.

The aim of the invention is to improve the reliability of operation by compensating for non-synchronous operation of devices.

This is achieved by the fact that the reloading body is made in the form of a driving carriage with a lifting and lowering platform mounted on rail tracks of caches along the storage conveyor and in the zone of the device for single-piece dispensing , while the trolley drive is equipped with a troso-block system.

FIG. 1 and the machine is shown; pas figs. 2 - devices and final switches, open, full view; in fig. 3 - unloading authority and equalizer.

The machine consists of a device 1 for stacking and a device 2 for single delivery with an equalizer 3, connected by a conveyor belt 4 with a reloading body 5. The device for stacking is performed in the form of a lifting and lowering table 6, racks 7, forming their shaft. To the ends of the racks 7

the blinds 8 are attached, connected by a power cylinder 9 and equipped with limit switches 10 and 11. Below racks 7 are placed the clamps 12 connected to the power cylinder 13 and the limit switch 14.

The lifting and lowering table 6 is made in the form of screw mechanisms 15 which are pairwise connected by a crossbar 15 and equipped with a drive 17, a command switch 18 made as a staple 19 with petals 20 interacting with limit switches 21-23.

The device for single-piece delivery made in the form of a lifting and lowering table 24, racks 25, grippers 26 with power and 27 27, dogs 28, interacting with kopeknymi

switches 29 and 30.

The lifting and lowering table 24 is made in the form of o2 screw mechanisms 31 which are pairwise connected with a crossbar and equipped with a drive 33, which interacts with end switches 34-37, and a comaid device 38.

The conveyor drive 4 consists of two parallel circuits 39 arranged in parallel with leading sprockets 40 interacting with a limit switch 41, and is equipped with a drive 42, tension sprockets 43 and a limit switch 44. Rail tracks are placed between the drive conveyor 4 between its chains 4. guides 45, one end of which is located in the area of the device 2 for a single-piece dispensing. On rail guides 45 there is a transshipment body 5 made of a driving carriage 46 with a lifting and lowering platform 47, the drive 48 of which is equipped with a traction body in the form of a troso-block system 49 interacting with limit switches 50 and 51; The lifting and lowering platform is equipped with limit switches 52 and 53.

Equalizer 3 is made of two cheeks 54, interacting with the limit switches. l mi 55 and 56.

The work of the maschina is carried out as follows.

The products enter the curtains 8, after which the cylinder 9 is commanded, and the curtains 8 are opened, the product passes, which under its own weight falls into the platform on the crossbar 15 of the lifting-lowering table 6, after which the curtains 8 are closed and the limit switches 10 and 11 determine the height of the 15 items accumulated on the rungs.

If the product is at the level of switch 11, then it turns off cylinder 9 and issues a command to lower table 6 before closing switch 21 and stop drive 17. After table 6 is lowered, the switch will close again and the cycle will repeat until the crossbar 15 The table 6 will not be below the level of the chains 39 of the storage conveyor 4. The pack that has been formed from will remain on the conveyor 4. After the circuit breaker 22 is closed, the cylinder 13 is turned on and the supports 12, on which the incoming products accumulate, and the drive is turned on. Yes, 42 of the storage conveyor 4, and a chain with a bundle on the schag is moved to the closing of the switch 41, which stops the drive 42 and gives the command to switch off the drive of the table 6 motor. Crossbars 15, lift, abut against the products collected on the pickups, and lift they are at a certain height before closing the switch 23, which turns off the drive 17 for raising the table 6 and turns on the cylinder 13 to take the pickups 12. The output of the pickups is controlled by opening the limit switch 14.

After the storage conveyor 4 is filled, the switch 44 closes, a filling tone sounds. When filling the storage conveyor 4, the lifting table 6, having formed a stack of products, lowers it onto the chain 39. of the conveyor 4, but cannot rise after the next one, the products fully load the tappings 12 and open the limit switches 10 and 11, which stop the supply of products to the machine .

After the storage conveyor 4 is full, the drive 48 is turned on, and the cart 46 moves to the conveyor 4, comes under the nearest pack, after which the pack presses the switch 51, which turns off the drive 48 and turns on the lifting of the platform 47. The stack of products rises above the conveyor, releasing the end switch 51, and before the circuit-breaker 52 closes, the actuator 48 turns on. The cart with the pack in motion moves along rail guides 45 to the reloading unit 5, and the command to lower the platform 47 comes from the end switch 50. If ly well lies on the platform, the switches are closed 55 and 56, and the drive 48 receives a signal of readiness to 46 carts dalneyschih movement. If the packet is shifted to platform 47, then the command for alignment is received, after which the signal is sent to the actuator 48 to indicate that the platform 47 is ready for the displacement, and this will only happen

in the case when the table 24 takes the lowest position by closing the switch 36. The cart 46 enters the area of the device for dispensing products and stops from the switch 51 exactly along the axis of the lifting and lowering

table 24. From the switch 51, the command is sent to the drive 33 of the table 24 to lift the stack of products from the cart 46. The lift is carried out before closing on the interlock; 38 of the limit switch 35, and the cart 46

returns for a new bundle.

The gripping mechanism picks up products from the lifting and lowering table 24 and transfers them to the pawls 28, from where they are fed to the overhead conveyor.

The operation of the device for single delivery occurs similarly to the device for stacking. but in a different sequence.
