Description

(54) LOADING AND UNLOADING DEVICE

one

 The invention relates to such industries as mechanical engineering, instrument making, etc., where it is required to issue parts to the processing position by piece, and unloading is subject to requirements excluding the application of scratches and impacts of external surfaces against each other.

Known loading and unloading device, containing the body, shops loading and unloading, the feed gate with slots and lifts parts 1.

A disadvantage of the known device is that it is impossible to supply details of a complex configuration and high surface purity.

The purpose of the invention is to improve the reliability of the device when supplying parts of complex configuration and eliminate damage to the outer surface of the parts.

The goal is achieved by the fact that in the cut-out on the basis of the body in the loading and unloading positions there are cut-off devices, and the loading and unloading magazines are made in the form of two discs that can be rotated and squares, rigidly

mounted on the discs and forming a vertical cage for parts, while the gate is interoperable with the load magazine cut-off device by means of the

 stop mounted on the gate.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 3

10 On case 1 there are loading and unloading stores, representing ush, disks 2 and 3 mounted on rotating axis 4 mounted in bearings 5. Disk 2 is rigidly connected to the axis by means of a key, and disk 3 is pressed to it by a spring 6. The base squares 7 and the spring-loaded squares 8 are mounted on disks 2 and 3, respectively, to form clips for parts 9. The details in the cages lie on round tables 10 and 11 and slide along them

20 when turning the dial. In the cutout of the loading round table 10 on the axis 12 a cutter 13 is installed, made in the form of a damper with a spring-loaded stop 14 and a spring 15. In the cutout of the unloading table 11 on the axis 16

a cutter 17 is installed, made in the form of a valve with a spring 18. The stop 19 serves to limit the movement of the shutter.

The feed gate 20 with an oblique stop 21 on the upper surface and sockets for fixing the parts a in the machining zone, b in the unloading zone is moved by the hydraulic cylinder 22 in the guides, transferring the part along the plane of the housing 1.

The elevators in the machining and unloading area are, respectively, hydraulic cylinders 23 and 24, the rods 25 and 26 of which serve to move the parts, and the rod 25 with them, has grooves for the tool to run. The limit switch 27 provides a one-step synchronous rotation of stores when releasing the next cage of parts in the unloading store.

The device works as follows.

The workpiece is dispensed by reciprocating movement of the spigot 20. When the gate moves for the first time without parts, the stop 21 releases the slam-shutter 13, which is rotated on the axis 12 by the action of the spring 15, and the entire cage of the parts 9 falls on the top surface of the gate, which slides on movement. The movement of the gate 20 stops in contact with a fixed stop (not shown). There is a movement of the rods 25 and 26 of the hydraulic cylinders 23 and 24 without parts in the upper position. Gate 20 returns to the loading position. The stop 21, acting on the cutter 13 through the spring-loaded stop 14, cuts off the second part from the bottom and at the end of the gate of the gate 20, the bottom part of the sleeve enters the socket a - the gate of the gate 20 is loaded, the lifts 23, 24 are lowered to the bottom position. When the gate 20 moves to the treatment area, the slam-shut 13 is released and all parts fall onto the upper surface of the gate and when it stops, the hydraulic cylinders move upwards. The rod 25 centers the part and in the upper position presses it to the clamping surface. Processing is performed. Gate 20 is again retracted to the loading position, and the workpiece falls into the socket. The rods 25 and 26 are lowered to the lower position, with the finished part falling into the socket b. When the spine moves to the machining position, the machined part is above the rod 26, and the next blank from

the boot clip is above the stock 25. The rods are moved to the upper position: the workpiece is machined, and the machined part, centered on the rod 26, rests on the taper bore of the shutter 17, stretches the spring 18, the flap turns on the axis 16 and passes the part -shop storage unloading. The loop movement cycle is repeated until no detail remains in the store.

Then the stop 21 of the shutter 20 in the loading position turns the shut-off device 13 to a larger angle and the limit switch 27 is activated - the loading magazine and the unloading shop are rotated one step. When the discs 2 and 3 are rotated, the angled squares 7 move around the parts, which slide along the round tables 10 and I, respectively, and then run over the shut-off devices 13 — in the loading table of the store and 17 — in the unloading shop. The work cycle is resumed.

The application of the invention will improve the reliability of the device when supplying parts of complex configuration and high surface purity.
