Abstract

Use for pad printing of buttons and can be applied in metal fittings enterprises using buttons in consumer goods SUMMARY OF THE INVENTION Summary of the invention: an automatic line for coating buttons is provided with a device for applying a pattern including a rotary table with sockets. The invention relates to the manufacture of buttons, namely, devices for applying a drawing by pad printing. Known machines - semi-automatic machines for applying a picture to products of large dimensions from ozhi, cardboard, paper, plastics, followed by drying them in a convection oven. Their main disadvantage is the need to reload the products after drawing the pattern into the drying chamber, which significantly reduces the productivity and repair of parts, a conveyor for moving parts through the operations of the process and control system. What is new in the line is that the part removal mechanism is provided with a spring-loaded movable bottom, which is installed in the rails at the bottom of the turntable socket. The bottom has a groove for extending the button leg, ending in a cylindrical hole larger than the diameter of the button, ending in a cylindrical hole larger than the diameter of the button. A horizontally-closed step-by-step conveyor passes under the table, which is equipped with platforms in the form of rectangular cells with jumpers pointed to the upper plane of the platforms. The platforms are periodically stopped under the nests of the rotary table in the load position. On the lower part of the conveyor there are cams interacting with the moving bottom and the working body of the subsequent technological process, for example, a 10-spray gun. contributes to damage to the printed pattern. The closest in purpose and technical essence are pad printing machines designed for printing on various products, including buttons. They consist of a rotary table, a printing unit and an infrared lamp and provide a high-quality invention. However, to preserve the pattern, it is necessary to protect them with varnishes when the curing is hot.

Description

otherwise, it is damaged in any type of feeder.

The lack of varnishing and drying devices is the main disadvantage of these machines,

To fix the pattern on these machines, the buttons must be manually placed on the baking sheets for varnishing and drying, which leads to an increase in labor input and a decrease in productivity.

The aim of the invention is to increase the productivity and quality of workpieces.

An automatic line for printing and coating buttons such as buttons includes a base mounted device for patterning, including a rotary table with product slots, a product unloading mechanism, a coating and drying device, and a control system. This goal is achieved due to the fact that the product unloading mechanism comprises a movable plate with a curly through groove connected to the control system installed in the guides of the turntable mounted on the bottom of each seat of the turntable, and one part of the groove is designed to hold the product, and the other for its unloading, and the carriers of the conveyor products are made in the form of a cell pads, the surface of the jumpers which are made pointed, with the possibility of placing a movable plate under the discharge and associated with a control system, the latter being associated with a varnishing and drying apparatus.

This design of the line allows to increase productivity and quality of the processed products due to the fact that the buttons after applying the images to them are automatically transmitted without touching the image with each other or with the mechanism on the conveyor for subsequent application of the protective layer of varnish and drying of the coating.

Figures 1, 2 schematically show an automatic line for printing and coating a button-like article; Figs. 3 and 4 show a rotary table with a mechanism for removing parts; figure 5 - movable plate; Figures 6 and 7 show a layout of the platforms and control cams on the conveyor chain; on Fig.9 is a diagram of the template in the position of varnishing; Fig. 10 is a control diagram of a dropper and a spray gun.

The automatic line consists of a device for applying a drawing 1, including a driving rotary table 2. a pad printing unit 3. a drying unit of a drawing 4, a feeder 5.

Table 2 has slots 6 for placement

buttons 7.

Each socket 6 in the bottom has a guide movable plate 8, spring-loaded from the center by a spring 9. To limit the stroke, the movable plate 0 by 8 is equipped with a pin 10, which runs in the grooves 11 of the rotary table 2. At the bottom of the table 2, guides 12 for the movable plate 8 are fixed The movable plate 8 has a figured through groove 13 for extending the button leg and with a cylindrical hole larger than the diameter of the button 7 to eject the latter in the Unload position.

In the Unloading position, the pneumatic cylinder 14 is installed, the rod 15 of which is directed towards the rotary table 2.

Under the table 2 there passes a chain horizontally-closed conveyor 16 of step movement, on the links x of the chain 17 of which

5, mesh pads 18 are fixed through a step with the size of rectangular cells aa larger than the diameter d of the button leg 7.

The bearing surfaces of the crosspieces of the mesh pads are made pointed 0 to the bottom of the chain 17 rigidly through a step

command cams 19 are fixed, interacting with an electric command apparatus 20, giving a command to 5 pneumatic distributors with electric control 7 and to an electric motor 22, which drives the conveyor 16 through the gearbox 20, transmission 24.

In the Painting position above the transport-Q rum, a lacquering device is installed in the form of an automatic spray gun 25, to which paint is supplied by compressed air from the paint-injection tank 26. The inlet of the pneumatic cylinder, including the edge of the atomizer 25 (opening its needle), is connected with the outlet of one of the pneumatic distributors 21.

Between the button 7 and the spray gun 25, a template 27 is installed with an opening Q 28 equal to or larger than the diameter of the button 7, below which there is a container 29 for collecting lacquer that has fallen on the template 27.

After varnishing, the button 7 enters the drying device 30 with electric heating,. bodies 31, at the exit of which it is removed to the collector by suction 32.

The control circuit also includes a valve 33, a filter - water separator 34, a pressure reducer 35 with a manometer 36 and an oil separator 37,

The device operates as follows.

By opening the valve 33, compressed air is supplied to the air distributor m 21, then to the overheating tank 26 and the varnish from it enters the automatic spray gun 25.

Button 7 is poured into feeder 5.

When the feeder 5 is turned on, the buttons 7, oriented, fall into the slots 6 of the rotary table 2. When the table 2 is moved, the button 7 enters the pad printing position, where the pad printing unit 3 draws a drawing. Then the passage under the drying unit of Figure 4 passes through drying it by heating.

At the next turns of the table 2, button 7 enters the Unloading position, where the movable plate 8 is turned against the pneumatic cylinder 14. At the command of the cam 19 of the control unit 20, the electromagnet of the air distributors 21 is triggered by the cycle and air enters from the rodless cavity of the pneumatic cylinder 14,

The rod 15, abutting against the movable plate 8, compresses the spring 9, pushes the plate 8 and the button 7 through the cylindrical hole of the figured through groove in the plate falls onto the mesh platform 18 of the conveyor 16.

Since the size of the rectangular cells of the area a x a is larger than the diameter d of the button leg 7, and the bearing surfaces of the jumpers are pointed, the button is easily guided into the cell and lies on the pad without damaging the pattern.

The time relay relieves the command from the pneumatic valves 21, they return to their original position, the air enters the rod cavity of the pneumatic cylinder 14 and the rod 15 returns to the rear position, the spring 9 returns the movable plate 8 to its original position until the stop 10 touches the edge of the groove 11 of the table 2. Chain 17 of the conveyor 16 is moved until the next cam 19 is pressed on the command device 20, after which the engine 22 is turned off, the chain stops, and again the pneumatic valves 21, one of which is operated by the pneumatic cylinder 14 in Play next button 7 on

the next platform 18, and the second, the output end of which is connected to the pneumatic cylinder of the automatic paint dispenser 25, opens it, and spraying and varnishing of the button in the Painting position through the pattern 27 with the hole 28 is not necessary. The varnish that has fallen on the pattern 27 drains in the capacity for collecting varnish 29.

The cycle of displacement-unloading-varnishing is repeated through the interval set by the time relay.

After varnishing, the buttons 7 on the pads 18 get into the drying device 30, where under the influence of

Electric heaters 31 are hot drying varnish. After drying, the finished button with a securely protected varnish pattern is removed by suction 32 in the product collection.

The diagram conventionally shows one button in each position. Their number can be any and is determined constructively.
