Description

In the production of pencils, devices for coloring pencils are known, including a loading hopper, periodically vras, ayush, ice a drum with sockets on the periphery and coloring, rollers with a colorful bath. In such devices, colored pencils are usually laid to dry on special cassettes or a conveyor belt of significant length is used, which makes the device cumbersome and complicates the process of drying pencils.

The proposed device provides a simpler and more convenient way of laying colored pencils to dry. For this, it has a magazine consisting of upper and lower coils, a roller feeder mechanism and two conveyor belts rewind from one coil to another and used to grip colored pencils located between the coils of the tapes on the top coil, the axis of which has the possibility of free non-displacement vertically.

The device can operate without stopping, for which the magazine is made detachable and mobile on rollers. FIG. 1 shows the layout of the store; in fig. 2 is a diagram of a roller feeder; in fig. 3 - a general view of the device, front and side view.

On the stationary frame of the device are mounted a hopper 1, a periodically rotating drum 2 with peripheral slots for putting pencils and a painting apparatus 3 including a colorful bath and work rollers 4, 5 and 6. The frame also has an electric motor 7 which serves to drive the drum and paint rollers. A detachable, mobile on the rollers 8 store, consisting of the bottom coil 9, roller picker, is attached to the frame.

mechanism 10, the two conveyor belts 11 and the upper coil 12. The axis 13 of the upper coil has the ability to free mixing, and vertical in the slots 14 of the supporting bracket 15.

Pencils to be colored are loaded into a bunker, a colorful apparatus is filled with paint and a detachable magazine is adhered to the bed, after which the electric motor is turned on. From the bunker, the pencils enter the slots of the supply drum 2, which receives a periodic motion, moving approximately 60 ° through the Maltese mechanism. In the drum, the pencil is dyed with paint rollers and then falls onto the conveyor belts 11. The conveyor belts are driven by a roller feed mechanism, which in turn receives movement from the fingers 16 of the drum 2, periodically acting on the ratchet 17. Pencils are laid on the conveyor belts alone after another at regular intervals. Conveyor belts are rewound from the bottom roll to the top, clamping between the turns of the ends of the colored pencils. As the tape rewinds, the axis of the upper coil gradually moves upward in the grooves of the brace. After the magazine is completely filled with pencils, the limit switch is activated and the engine is turned off. The store is disconnected from the bed, moved to the drying room to dry the pencils, and in its place a free store is attached.
