Description

The invention relates to loading devices for periodically feeding a group of parts of a spherical shape during the mechanization of production processes in mechanical engineering.

The purpose of the invention is to simplify the design and increase the productivity of the device.

FIG. 1 schematically shows a device, a longitudinal section; in fig. 2 shows section A-A in FIG. 1, a two-way cut-off disc version; in fig. 3 - the same four-way variant of the release disk; in fig. 4 is a diagram of the position of the disk drive, the beginning of the period for feeding parts into the tray; in fig. 5 - this is the end of the period for feeding parts into the tray.

The device includes a housing 1, a fixed cut-off 2 with a screw groove 3, a rotating storage drum 4 mounted on the shaft 5, and a hopper 6. The cut-off 2 is made with a single or multi-start screw groove, the upper end surface 7 of which has a groove winding output 3, mates with the lower end surface 8 of a rotating storage drum 4 mounted above it, concentrically located in the cylindrical part of the hopper 6. Rotating storage drum 4 has slots 9 made in the shape of one or several equidistant along the circumference of the channels.

The upper conical part of the storage drum 4 is provided with agitators 10 arranged along a cone-forming element.

The device works as follows.

In the hopper 6, spherical parts 11 of a given nominal value are loaded. Through the drive shaft 5, the torque is transmitted to the storage drum 4.

Through the conical wall of the hopper 6, using the turners 10, which are located along the cone of the storage drum 4, the parts 11 move and fill the channels of the sockets 9, arranged in vertical columns with a guaranteed clearance between the surface of the channels and the inner wall of the cylindrical part of the hopper 6.

Located in the nest 9, the columns of the parts 11 reach the upper end surface 7 of the trimmer 2 and move along it with the end face of the wall of the nest 9 to the windings of the screw grooves 3. Under the action of its own weight and weight of the entire column of parts 11 located in the nest 9, into the outlet winding screw groove 3 is sequentially fed the number of parts 11, equal to the number of channels of the socket.

In this case, the group loading of the screw groove 3 occurs along one spherical part successively cut off by its opposite sharp edge from the rest parts remaining in the column. Thus, one detail is taken from each column of socket 9 without causing the entire column of parts to hinge and not overcoming their weight load.

So, when four parts are taken from slot 9 in a two-way disc-shutter, a single-time feed is supplied to 8 pieces of equipment in the equipment loading position, while four-way discs and a shut-off disc are 16 pieces, while intake, for example, of parts from a slot in a two-way disc - 12 pieces of parts are supplied to the shutter; 24 pieces of parts are used in the four-entry design, etc.
