Description

Known disk bunkers, mowing an inclined bowl with a fixed bottom, rotating dns with a nazamn, a cutter and a receiver for parts, are unreliable in operation, as they allow cases of non-recut and jams of blanks.

In the proposed bunker, an intermediate magazine was used in a vnde through window in a fixed disk. This disk is bounded above by the plane of the movable disk, and below by the surface of the drive.

A spring-loaded stopper is installed in the receiver, which prevents the item from being accidentally dropped into the feeder. This design increases the reliability of the bunker.

FIG. 1 shows a diagram of the described bunker; on fng. 2 is a diagram of the storage device of the bunker mechanism with the upper part of the power supply; in fig. 3 - lines with electromagnetic shut-off.

The bunker mechanism consists of a bunker 1, a working rotating disk 2 with grooves for workpieces of parts located in the tangential direction, and a stationary disk 3 having a discharge window that communicates with the receiver 4 of the electromagnetic shutoff feeder. Electromagnetic cutter has a solenoid 5, a system of three levers 6, 7 T S, a return spring 9, working for stretching, and a pushing bar 10 connected to the lever 6. Pushing the bar 10 with its end can move progressively in the receiver 4 of the feeder. The transfer of movement to the working disk 2 is carried out from the machine or automat pinch through the brush 11, shaft 12, worm gear 13, shaft 14, bevel gears 15 and 16 and shaft 17. The magazine device (fit. 2) is designed to receive a certain number of parts ( the diagram shows the magazine for the three parts 18, 19 and 20). Detail 20 is located at the exit and lies on the surface of the feeder. The part 21 moves along the feeder when the pushing bar 10 moves. The magazine space is formed by the cutout of the unloading window of the fixed disk 5. From the spontaneous slipping into the feeder, part 20 is held in the magazine with a spring-loaded finger 22. The electrical circuit (Fig. 3) consists of a step-down transformer 23, you # 144378-2 -

A relay 24, a switch 25 connected in series with the relay coil 26. The contacts of this relay are installed in the circuit of the solenoid 27 and open when current flows through the coil of the relay 26.

The operation of the bunker device with an electromagnetic shutoff is as follows.

When the working disk rotates, 2 parts fall into the slots (windows) of the disk. When the working disk passes over the unloading window of the fixed disk 3, the button of the switch 25 moves to its extreme position. The relay coil 26 is de-energized and its contacts open. Under the action of the spring 9, the lever 6 is rotated counterclockwise and the pushing bar 10 will send the bottom blank from the magazine to the feeder flow. By the same stroke of the pushing plate, the whole set of parts in the tray is sent forward. With further movement of the working disk button 25 switches to its original position. The contact is closed and the solenoid circuit is activated. When activated, the solenoid retracts the push bar in the rear position. The space for the next workpiece is cleared and the parts in the store are lowered. If the magazine, at the moment when the slot of the work disk with the workpiece passes over it, will be filled, then the workpiece lying in the slot of the work disk will slip along the upper plane of the top workpiece located in the shop.

The supply of parts using the pushing plate, the presence of a special magazine with a constant number of blanks, the implementation of synchronization of the pushing plate movement with the rotation of the working disk using a solenoid, a relay and a special switch avoids jamming or skewing the blanks when moving them through the discharge window to the receiver of the feeder.

Testing the proposed design of disk bunkers for flat parts at one of the plants of the Leningrad Economic Council gave positive results.

Subject invention

A disk bin for flat parts consisting of an inclined bowl with a fixed bottom, a rotating disk with grooves, a cutter and a receiver for parts, characterized in that, in order to increase the reliability of the bunker, an intermediate magazine is made in the form of a through window in the fixed disk bounded above by the plane of the movable disk and below by the surface of the receiver in which a spring-loaded stopper is installed to protect against arbitrary parts getting into the feeder.
