Description

Devices are known for feeding materials, preferably empty spools, for example, to containers of a workshop conveyor for distributing spools to bunkers of automatic rewinding machines that have a loading tray, a vertical stepping conveyor with articulated buckets fitted with protrusions that interact with the tilting mechanism, and Yush, and trays.

In order to better synchronize container loading, the tipping mechanism in the proposed device is designed as buckets mounted in the path, a vertical conveyor lever, interacting with buckets protrusions for tipping and unloading them and installed in an operating position by an electromagnet that receives a pulse from the container of the workshop conveyor that imparts a pulse at the same time and drive vertical vertical conveyor.

The device can be equipped with a transporter dispenser, made in the form of two gate valves installed in the loading tray and synchronously moved by means of a crank mechanism, and a slide for unloading conveyor buckets and a chute for returning the transported bobbins to the loading tray.

FIG. 1 schematically shows the proposed device; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 and 4 — tipping bucket mechanism.

No. 150783-2 -

The vertical frame / mounted guide and drive sprockets 2, in which two chains of the conveyor 3 are located, driven by the electric motor 4 through the coupling 5, where the tension of the chains is provided by the tensioning device 6.

Eighteen buckets with protrusions 7 are pivotally mounted on the chains, to load the buckets in the lower part of the device there is a loading chute 8, and below it a dispenser 9, gate valves 10 of which are driven by a crank-crank mechanism / L in the loading chute. Electrical contacts 12 are mounted on the frame of the device, which, when interacting with the levers J3 of the chambers of the container 14 to be loaded, give impetus to the tilting mechanism of the buckets 15, and the electric contacts 16 that impulse the device to the electric motor. In the upper part of the frame, there are guide trays 17, slide 18 and chute 19 for returning the spools to the hopper. The tilting mechanism of the buckets is made in the form of a lever 20, the axis of which is a spring-loaded roller 21 with a spring 22, passing through a sleeve, on the movable part 23 of which is a tooth 24, which is closed in a non-working half-section with a spring-loaded pin 15, opened by an electromagnet 26.

The device works as follows: when approaching an empty container, its levers-signaling devices 13, interacting with electrical contacts 12, turn on the electrical contact 16 of the tilting mechanism that opens the latch 25, freeing the clutch tooth 24, the spring-loaded roller 21 rotates 60 ° and moves the lever with the help of a spring 22 20 in axial direction. The lugs of the bucket slide onto the semicircular surface of the lever 20 and drag it along its course along the chain forward, while one side of the bucket tilts down and the spools go through the guide tray 17 into the chamber of container M.

After removing the spools, the empty bucket moves forward, the protrusions are released from engagement with the lever, which moves to the side along the roller 21, the shekold 25 closes the coupling tooth, and the lever is held by the spring in a vertical non-working position.

When removing empty buckets, the bottom electrical contact 16 turns off the electric motor 4 and the next pair of buckets with spools goes to the tipping mechanism.
