Description

one

The invention relates to machines for producing rods of dimensional bars, namely, devices for the piece issuing of rods, rods, etc. items.5

A device for supplying longitudinal rods in machines for welding reinforcing meshes is known, comprising a hopper mounted on a frame and a mechanism for issuing rods from a hopper with 10 actuators in the form of a power cylinder l.

A disadvantage of this device is the lack of guarantee that the bar will fall into the slot of the hopper.

The purpose of the invention is to increase the reliability of the operation of the device, i.e. ensuring reliable delivery of bars in one of the bunker loaded with measuring bars.

The goal is achieved by the fact that in the device for the single issue of bars, containing a bunker mounted on the frame and a mechanism for issuing bars from a bunker with a drive in the form of a power cylinder, the mechanism for issuing bars from the bunker consists of vertical guides placed on the frame, placed on them are carriages, clamps and three-way arms with stops placed in horizontal directions - 30

two double-arm levers hinged and fixed on the carriage, one of which interacts with one end of the clamp and one with the other; cylinder, while the other lever at one end interacts with stops grabs, and the other with the power cylinder, and the restrictive roller, placed on the frame, and in contact with the end surface of the clamp.

FIG. 1 schematically shows the proposed device, side view, in FIG. 2 - the same, front view, in FIG. 3-9 - a full cycle of capture and issuance of the bar.

Claims (1)

The device consists of a base 1, on which vertical guides 2 are fastened, along which the carriage 3 moves progressively. The carriage is driven by a translational mechanism, for example from hydraulic cylinder 4 through two shoulders levers 5 and 6, and axle 7. Two shoulders levers are seated on axis 8 carriages. Two grippers 10 with stops 11 are placed on the carriage in transverse guides 9. The grippers are connected by cylindrical rollers 12, along which the clamp 13, which has oval paea, moves. A stop is fastened on the clamp. 14, Both grippers 10 and clamp 13 are interconnected by springs 15. On the vertical guides 2, a ba face with a stop roller 17 is installed to limit the movement of the clamp on the right. Based on 1, there are two flat triangles 18, which are about. develop the vertical knife supports of the bunker and bevels for the discharge of the rods. The second pair of triangles 19 forms inclined knife supports of the bunker. The side walls of the hopper 20 are fixed to the base 1. The measuring rods 21 are loaded in the hopper. The device for single-piece delivery of the rods works as follows. When the rod of the cylinder 4 moves upwards, it acts through axle 7 on two shoulders levers 5 and 6, turning them around the carriage axis 8 clockwise, while the two shoulders levers 5 move the grippers 10 through the stops 11 to the right until they stop at the ends of the upper guides 9, The clamp 13, which is connected to the grippers 10 by the springs 1, remains in place, resting its ground plane in the restriction roller 17. As the cylinder rod moves further, the carriage 3 starts to move upwards, with the grips 10 going through the hopper in the area of the rods catch one fallen rod and moving it up until the overlying clamping rods 13 will not descend with restriction roller 17 by springs 15 and a rod prohibition sunken grips, at this position the grippers 10 and the clamp carriage 13 with the rod 3 is raised to the upper dead point. After receiving the command to move the cylinder rod down, the latter. .. impact on two shoulders levers 5 and 6, cause them to rotate counterclockwise, while the two shoulders lever b through the stop 14 moves the press 13 to the left, carries the grippers 10 with the bar clamped through the springs 15, pulling the latter onto bevels for dumping the bars 18, The grippers 10 move to the left until they stop against the end surface of the upper guides 9, and the clamp 13, continuing to move to the left, unlocks the gripped bar. After fully unlocking, the carriage 3 starts to fall down and the bar rests on the bevels to drop the bars, and the clamp 13 is moved outside the hopper zone to the lower position. Then the cycle is repeated. The use of the proposed device for single-issue delivery of P 3-days in mesh manufacturing machines increases the reliability of the machinery, improves the quality of the manufactured grids, due to the rhythmic feed of the rods, eliminates the time-consuming operation of supplying the measuring bars of the reinforcement and reduces labor costs. Claims An apparatus for single delivery of rods containing a hopper mounted on a frame and a mechanism for issuing rods from a hopper with a drive in the form of a power cylinder, is different. In order to increase the reliability of operation, the mechanism for issuing bars from a bunker consists of vertical guides placed on the frame, a carriage placed on them, a clamp and grippers with stops, placed in horizontal guides and springs interconnected two shoulders, hinged on the carriage, one of which at one end interacts with the stop and the other with the power cylinder, while the other lever at one end interacts with the stops of the grips, and the other with the power cylinder, and restrictive roller placed on the frame, and in contact with the end surface of the clamp.
