Description

The invention relates to the handling of piece goods, in particular postal parcels.

The purpose of the invention is to increase the safety of goods.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the node of the control system for the reverse movement of the telescopic section.

Device for handling piece goods 1-6 contains a belt conveyor 7,

The bulk is located outside the landing site. Unloading such a load leads to the fact that it does not fit entirely on the unloading platform, in this case on tape 10, fall from it either at the time of unloading, or during further transportation, which will lead to damage to the cargo. To prevent this from happening, the control system commands the moving section 8 in the opposite direction not to the full

equipped with an output telescopic sec the value of M, equal to the total width of the area

8 with a drive 9 extension.

The conveyor 7 is mounted so as to extend the telescopic section 8 above the tape 10 of the other conveyor 11 to the full width M of its tape 10 until it touches the restrictive wall 12.

The conveyor 11 also has a telescopic exit section 13 provided with an extension drive 14. Section 13 has the ability to extend over the container 15 to its entire width M.

The device also includes sensors as well as drives 19 and 20 of conveyor belts 7 and 11, respectively.

Sensors 16-18 are connected to a control 21 control unit including adders

ki unloading (tape), and by an amount equal to the total length of goods 1 and 2, taking into account the gaps D between them, is the difference between the width of the tape M and the part K of load 3:

After the weights 1 and 2 have been unloaded onto the belt 10, the telescopic section 13 of the conveyor 11 extends (synchronously with the movement of the belt) in the direction of the container 15 until the most

° wide of the weights (in this case, the load 2) will completely go past the sensor 17. Then, by extending the telescopic section 8 of the conveyor 7, a new row of weights is formed on the belt 10. In this line, load 3 will be the first.

which are made on the trace element base series 155.

The device works as follows.

Weights 1-6 are individually fed to the conveyor belt 7. Then they are moved by the telescopic section 8 until the first of the goods 1 is in contact with the restriction wall 12. The contact is fixed by a sensor (not shown). During the movement of the telescopic section 8 the drive 9 of the extension of the section 8 and the drive 19 of the movement of the tape work synchronously.

When the section 8 extends over the belt 10, which in this case acts as a discharge site, loads 1-3 sequentially pass by the sensor 16, for example, photoelectric. The sensor 16 supplies signals to the control system 21 proportional to the lengths of successively passing loads.

As soon as the load 1 passes the sensor 16, the signal is fully proportional

This promotion continues

30 until the row consisting of loads 1 and 2 horizontally moves closer to the rear wall of the container.

This progress of the rows continues until the row consisting of loads 1 and 2 reaches the rear border of the container, which is detected by the last of the sensors 18.

If at this moment the last row completely fits in the dimension L (L is the width of the container), then the entire layer is unloaded by reversing the telescopic section 13 of the conveyor 11. But more often when the first row reaches the rear of the container 11. near the rear wall of the con40

its length, i, goes to the adder 22. After 45 tons of iner, the last row is covered by the sensor

17, i.e. it does not fit entirely over the receiving area. In this case, all the rows except the last one are unloaded into the container. In this way, a layer of weights is formed, which is then lowered down into the depth of container 50-15. The process of lowering the layer of weights is controlled by a set of sensors 18.

passing completely past load cell sensor 16, its length 2 is added to length C | cargo 1 taking into account the gap between the goods. The load 3 by the time the load 1 reaches the wall 12 entirely by the sensor 16 does not pass. A portion of its length, equal to K, is located above the landing site, and the remainder is located outside the landing site. Unloading such a load leads to the fact that it does not fit entirely on the unloading platform, in this case on tape 10, fall from it either at the time of unloading, or during further transportation, which will lead to damage to the cargo. To prevent this from happening, the control system commands the moving section 8 in the opposite direction not to the full
