Description

one

The invention relates to packaging, in particular to installations for packaging sheet glass in cases.

A similar installation is known, comprising conveyors for feeding glass and boxes, a lifting and lowering mechanism for receiving and a mechanism for transferring glass.

The proposed installation forms a glass package directly in boxes. This is achieved by the fact that the mechanism for overloading the glass is made in the form of an endless perforated tape, the envelope of several vacuum chambers installed with the possibility of plane-parallel movement in a vertical plane, and the mechanism for receiving the glass is provided with a table.

To ensure loading with a continuous flow of glass, the speed of the endless belt exceeds the speed of the glass feed conveyor.

FIG. 1 shows the proposed installation, top view, on FIG. 2 - the same, vertical section.

The installation for packing sheet glass in boxes includes a conveyor 1 for feeding glass 2, a conveyor 3 for feeding boxes 4, a lifting and lowering mechanism 5 for receiving and a mechanism for reloading glass made in the form of an endless perforated belt 6 enveloping several vacuum chambers 7 and installed with the possibility of plane-parallel movement in a vertical plane. The mechanism 5 for receiving glass is provided with a table 8.

In order to provide loading with flat glass flow, the speed of the endless belt 6 exceeds the speed of the conveyor 1 for feeding glass.

The force of the endless belt 6 is adjustable

counterweight 9. Vacuum chambers 7 are connected to ejectors consisting of nozzles 10 and diffusers 11, which are combined into groups by collectors 12 and 13. Valve 14 is installed in collector 12. Sensors 15 and 16 are connected respectively to gate 14 and spool 17. also includes the throttle 18 and the spool 19. The mechanism 5 is connected to the hydraulic cylinder 20.

The installation works as follows.

In the initial position, the conveyor 1 and the belt 6 operate at the same speeds; air is blown through the nozzles 10 with a pressure above atmospheric, the flap 14 is open, the box 4 is located on the table 8, the

to the uppermost position, the spools 17 and 19 are closed, the piston of the hydraulic cylinder 20 is in the left position, the sensors 15 and 16 are lowered, the conveyor 3 for supplying the boxes is off, the working fluid passes through the spool 19,

but the hydraulic cylinder 20 does not arrive. Glass 2

moves along conveyor 1, approaches the endless belt 6, which sucks it.

Since the glass overlaps the perforations with its surface, and the tape 6 overlaps the vacuum chambers 7, then at the last, as the glass 2 passes under them, a vacuum is created, whereby the glass is held to this position by atmospheric pressure.

On the approach to the loading position in box 4, glass 2 acts on the sensor; 16, which leads to opening of the spool 17. With the open spool 17, the working fluid in the hydraulic cylinder 20 is able to flow from one cavity to another under the influence of the weight of the table 8 with the drawer 4, the result is that the table with the box goes down at a speed limited by the setting of the throttle 18.

Upon further movement, the glass 2 acts on the sensor 15, as a result of which the valve 14 is turned and closes the collector 12.

As a result, the collector 12 in the group of vacuum chambers 7 connected to it overlaps the pressure very quickly above atmospheric, and the glass 2 is discharged into box 4. The deprived supports of sensors 15 and 16 are lowered, opening the valve 14 and closing the spool 17. The descent of table 8 stops.

When the next sheet of glass 2 approaches the loading position, the cycle is repeated until the box is fully loaded.

When fully loaded, box 4 is lowered onto conveyor 3 and turns it on. During the approach of the next sheet of glass, the full glass loaded glass uk is removed from the loading position, it is replaced by an empty one, the arrival of which to the position is a command to open the slide 19, as a result of which table 8 with drawer 4 rises to its highest position, and the valve 19 closes, after which the table lift stops. With the approach of the next sheet of glass 2, the full cycle of loading the box is repeated.

In this way, glass sheets are delivered to the glass conveyor at intervals.

When sheets are fed in continuous flow, a portion of the rollers of the conveyor 1 at its end portion is supplied with overrunning clutches, and the speed of the endless belt 6 must exceed the speed of the conveyor 1. Under these conditions, the necessary interval between the sheets of glass will be formed during the transition of the sheets from the conveyor 1 to the endless belt 6
