Description

(5A) TRANSPORT TRANSMITTER

one

The invention relates to a machine tool industry, in particular to transport devices of automatic lines, and can be used to transfer light parts to a conveyor step while lifting to a small height.

A transfer conveyor is known that contains conveyor belts associated with a longitudinal movement drive. The lifting and lowering of the belts is carried out from the hydraulic cylinder driving the auxiliary composite rod with cams acting on the up-and-down rollers, along which parts 1 roll,

The disadvantage of this conveyor is constructive complexity.

Also known is a conveyor-transferor of an automatic line of metal-cutting machine tools, containing pivot rods with stops placed on them. Raising and lowering parts is carried out when the rods are turned, the cams of which act on the bearing surfaces of the part

However, this leads to a partial change in the position of the part under the action of lateral efforts of the cam that occur when the rods are rotated, since it is practically impossible to align the position of the cams on the rods under production conditions and to achieve synchronism of their action on the part.

In addition, the spherical cam point contact with the detail damages the bearing surface of the latter.

The purpose of the invention is to increase the accuracy (to improve the movement of the part and reduce damage to the bottom surface of the parts being moved.

The goal is achieved by

20 that the turning rods are provided with brackets, and the stops are made in the form of rollers accommodated in the said brackets with the possibility of rotation 3 In FIG. 1 shows a conveyor belt; general view; in fig. 2 is the same (VIEW from the side. The conveyor belt contains brackets 2 with paws 3 mounted on the swivel rods 1, on the axis 4 of which rollers 5 are located with the possibility of rotation around its axis. Work piece 6 is placed on rollers 5 and installed on intermediate positions on the transport rails 7. The pivot rods 1 are mounted on the rollers 8 of the carrier structure of the conveyor. The conveyor belt works as follows: When you rotate the rods 1, they turn the rollers 5 located in the brackets 2. rollers 5 move along an arc of a circle and bring the parts 6 on them to a height of N. Since the rollers 5 are movably located on the rods 1, turning the last parts 6 rises vertically without receiving any side displacements, which improves the accuracy of movements. rollers as an obstacle ensures contact of the part with the rollers along the line, which allows 3 to reduce specific loads on the lower bearing surface of the part, as well as to maintain the purity of the bearing surface of the part. In addition, the implementation of the stops in the form of rollers is more technological compared to the spherical surface of the stops of the known transport conveyor which is difficult to grind. Claims of invention The conveyor-transferor of an automatic line of metal-cutting machine tools containing pivot rods with stops placed on them, characterized in that, in order to increase the accuracy of movement of the part, the pivot rods are equipped with brackets, and the stops are made in the form of rollers placed in said brackets with the possibility rotation Sources of information taken into account in the examination 1.Voronichev N, M. and others.
