SU749695A1 - Apparatus for multicolour tinting of rod-like elements - Google Patents

Description

f

The proposed device is intended for applying multi-color paint coatings and can be used in the manufacture of parts such as rods, for example, karan-dash.

A device for multicolor coloring of rod elements is known, comprising an endless conveyor, a loading orienting device, paint baths, a drying cabinet and a device for unloading p. .

However, this device is complicated in construction and has significant dimensions .15

In the proposed device, the endless conveyor is made in the form of a multi-turn spiral tape with holes for the rod elements, the conveyor rollers 20 have annular grooves for the passage of the rod elements, and the loading device contains pincers with a pneumatic pneumatic piston installed between them. a cylinder, an air distributor with an electromagnet, and limit switches for controlling the latter, located under the tape in the loading zone of the rod, the output elements. This makes it easy to 30

device design and reduce its size.

FIG. 1 shows the described device, a general view; in fig. 2 - endless multi-turn conveyor with a drive; in fig. 3 - boot-orientation device; in fig. 4 loading device with clamped pincers; in fig. 5 - loading device at the time of installation of the core element in the hole of the tape; in fig. 6 is a circuit diagram of the device.

The device for multicolor painting of core elements contains colorful 1 and drying 2 compartments, vibrating bunker 3, transporting device 4, loading device 5 and ejector 6. To observe the process of painting and drying, the door 7 of the device is glazed.

Claims (2)

In the colorful compartment 1 there are three baths consisting of reserves. in a boil 8, in which a predetermined level of paint is maintained by a float-type device and a feed vessel 9. The drying compartment is a vertical cabinet with nozzles 10 and 11 for supplying hot air from the air heater 12 and removing exhaust air, and a tray 13 over which ready core elements. From the vibrating hopper 3, the elements are fed in an oriented position along the chute 14 to the piece feed mechanism consisting of spring-loaded cutters 15 and 16 and compartment control levers 17. The transport device 4 consists of an endless multi-turn rubberized tape 18 with holes and drive-driven systems 19 and the rejection of the knife 20 rollers. The movement of the tape is transmitted from the electric motor 21 through the worm gear 22, the belt 23 and the chain 24 transmissions and a set of gears 25. The loading device 5 consists of a pneumatic cylinder 26, quill 27, a slider 28 with tongs 29, a punch 30, springs 31 and 32, a mechanism for the additional orientation of parts consisting of two spring-loaded sponges 33 of a special form, a tracking mechanism comprising spring-loaded levers 34 and 35 with pins 36 and 37, limit switches 38 and 39 and air distributor 40. A device for multicolor coloring rod elements y to earn follows. The rod elements A to be painted from the vibrating hopper 3 enter the tray 14 and are held by the cutter 16. The drive electric motor 21 drives the gearbox 22, the chain 24 and the transmission belt 23 and the gears 25 are driven into rotation by the drive rollers 1 which move the belt 18. The pins The 36 and 37 spring arms 34 and 35 are constantly pressed against the conveyor belt. When the tape 18 is moving, the pin 36 falls into the hole and releases the lever 34, which, acting on the limit switch 38, provides the command to turn on the air distribution of the air cylinder 40 of the pneumatic cylinder 26. Compressed air entering the upper cavity of the pneumatic cylinder 26 / lowers the piston with the quill 27, a slider 28 with a tongue 29 and a punch 30. When the quill 27 moves down due to the presence of springs 31 and 32, the cylindrical part of the punch 30 moves relative to the protrusion of the shaft 29, clamping the element in them. Slider 28, revenue all the way, stops. Punch 30, continuing to move, with its conical part pushes pliers 29. At this, the element is released and pushed by the end of the punch 30 into the opening of the tape 18. As the tape 18 moves further, another pin 37 acts through the opening 35 on the end switch 39, which feeds a command to return the pneumatic cylinder 26 to the upper initial position. T ha associated with the quill 27 opens the slam-shut 15 and passes the next element into the slightly open tongs 29, and from / secater 16 holds the remaining elements in the tray 14. Subsequently, when approaching the loading device 5 to the next hole in the tape 18, the loading device operation cycle repeats. The elements installed in the holes of the belt 18 pass successively through the tanks of the 8 painting trays and the drying compartment. 2. The tank 8 of each bath is filled with paint of a certain color to a predetermined level. Thanks to the dipping of the elements to the desired depth, they are colored in a different color (staged coloring). In order to provide repeated passage of the elements A inserted into the belt 18 through the painting and drying compartments, the rollers on which the inserted elements pass along the concave surface of the belt 18 are made with special annular grooves. Painted and dried elements are pushed into tray 13 by means of a dumper 6. Claims of invention An apparatus for multicolor painting of core elements comprising an endless conveyor, loading orienting device, paint baths, drying oven and unloading device. However, in order to simplify the construction and reduce the size, the endless conveyor is designed as a multi-turn conveyor. spiral belts with holes for rod elements, conveyor rollers have annular grooves for passage of rod elements, and the loading device contains pincers with a punch installed between their cheeks, a pneumatic cylinder associated with it, an air distributor with an electromagnet and end switches under the tape in the zone - loading rod elements.
