Description

I

The invention relates to the field of industrial manufacture of miniature products, in particular classification equipment, and can be used in various control and sorting devices where it is necessary to sort products by parameters into a large number of groups.

A device for sorting miniature products into groups of tU comprising a housing with a vertical rectangular shaft, discharge chutes, electromagnets and dampers according to the number of sorting groups is known.

With this design of the sorting device, each valve has its own electromagnet controlled from a software device. When a large number of groups, for example 200 or more, the sequential arrangement of valves in the mine leads to an increase in the path of movement of the product through the mine, which reduces the speed of the device, reduces its performance, and also leads to a decrease in the number of actuators, and this reduces the reliability of the device.

It is also known to have a mine-type sorting device 2 containing a vertical shaft, diverting inclined chutes with a series of dampers mounted on common axes, electromagnets and cells for the length of products. This device has fewer executives.

10 mechanisms, but it also does not allow sorting products into 2OO and more groups.

. The aim of the invention is to increase the productivity and reliability of sorting.

This goal is achieved by the fact that in the known device, comprising a vertical shaft, diverting inclined chutes with rows of flaps mounted

20 on common axes, drive electromagnets, cells for products located along the MJ and a program device, each Russian contains two rows of cells, one above the other, and an electrically controlled plate with holes installed with the possibility of mounting by cell.

Fig, 1 shows a general internal device; in fig. 2 is a section A-A of FIG. one; in fig. 3 is a section BB of FIG. 2; in fig. 4 is a cross section of the EUB of FIG. h

The sorting device consists of a vertical shaft of 1 straight line with a horizontal section, on one side of which there are valves 2, made in the form of 1-plane springs made of a ferromagnetic material. One end of the zyslonok is fixed on the body, forming the wall of the shaft, and electromagnets 3 are installed against the other end, located on T1p () teVo the opposite wall of the shaft. The yolon 2 covers the inlets of the trays 4, which are open inclined to the horizontal plane in order to move the articles along the tray. The discharge chutes 4 are continued by the flaps 5, which close the shafts 6 with the cells 7 located under them. The flaps are fixed fixedly on the axes 8 and are controlled by one electromagnet 9 from the program device.

In the lower part of the device, under the mines 6, the Rus are located, consisting of cells 6 for products and bypass channels 10 alternating with each other, with the exception of the lower one where the cells do not alternate. A horizontal plate 11 is located above each channel with holes that distribute the product into the cell or into the bypass channel or into the cells on the lower Rus. The plate 11 is controlled by a single electromagnet 12 from the software device a and is reciprocated in the side walls.

The device for sorting works as follows. With a small number of groups sufficient for one Russ, the upper distribution plate 11 extends, and the bypass channels 1O are filled with cells 7 from the lower Russ.

All cells of the upper russa are assigned a sequence number corresponding to the group number. On command from the software device, electromagnets 3 and 9 of the corresponding OTKipflBakiT channels are dampers 2 and 5. The product is from the position of a cell in which it is measured

parameters, falls into the cell 7 of the corresponding group. With a large number of groups, when one Rus cell is not enough, some of them move out through a series of device Rus, forming alternating cells 7 and bypass channels Yu, along which products fall. After that, serial numbers are assigned to all the cells of the Rus. On command from the software device, the electromagnets 3 and half of the electromagnets 9, which open the corresponding channels of the vertical shafts 6, and the product falls through the bypass channels into the cell 7 of the lower

rusa

When using the cells of the upper Russ and the lower, which are not under the holes of the plates 11, electromagnets 12 are triggered simultaneously with electromagnets 3 and 9, the holes of the plate 11 occupy a position above the cells, and the product falls into the cell 7 of the corresponding Russ group.

The use of this distribution device allows to improve the performance and reliability of the device, to increase the number of groups of classified products.
