Description

(54) LOADING DEVICE

I

The invention relates to mechanical engineering and can be used to automate the loading of machine tools and automatic lines.

A charging device is known, which contains a bunker, a shaft pick-up with an axial bore, mounted with the possibility of reciprocating movement and connected with a source of vacuum 1.

A disadvantage of the known device is the ability to load only those parts, the axis of which is located coaxially with the axial hole of the rod grip, which reduces the performance of the device.

The purpose of the invention is to improve the performance of the device.

This goal is achieved by the fact that the device is equipped with an axial gripper installed fixedly and fixedly relative to it by an annular abutment, the working surface of which is made in the form of a spiral coil.

FIG. 1. shows the boot device built into the rotor; in fig. 2 - scheme of the device.

The device consists of a rod grip 1 with an axial bore 2, fixed

ring stop 3 with a working surface 4, made in the form of a spiral helix. These devices are built into the loading rotor, on the shaft 5 of which a disk 6 is fixed with fixed stops 3, coaxial rod grippers 1. In the drum 7 there are slide blocks 8, which are connected to the fixed copy 10 through rollers 9 on one side and grips 1. Axial holes 2 of gripper 1 are in turn connected through tubes 11, channels 12 and flat distributor 13 to a vacuum source (not shown). An asterisk 14 is rigidly fixed on the shaft 5 for the transport chain 15. A bunker 17 is located on the base 16. The diameter of the gripping hole is chosen smaller than the length of the part 18, but larger than its largest diameter.

The device works as follows.

In the hopper 17 in bulk are parts 18 (axes of the saw chain). The axial bore 2 of the gripper 1 is connected to a vacuum source. The gripper 1 under the action of the slide 8, interacting with the cam 10, is lowered into the bunker 17. Part 18 is attracted to its end face in any possible position. Capture 1 begins to move up, moving to

In the same direction, part 18. Part 18 has reached the stop 3, due to its working surface 4 being in the form of a spiral turn when part 18 is gripped so that its axis does not coincide with the axis of the hole 2, with one edge rests against the stop 3 and upon further movement of the gripper 1, it rotates in the direction of the axis of the hole 2. When a certain minimum angle is reached between the axes of the part 18 and the hole 2, the part 18 is detached from the stop 3 and sucked into the hole 2. Next, the oriented part is fed to the load, for example, transport grips oh circuit 15 or aa assembly.

Such an implementation of the device will ensure a 100% supply of parts to the working position at any opportunity of orientation at the moment of gripping, which will improve the assembly quality of the saw chains, eliminate

the time to stop the chain assembly line for skipping over the skipped position.
