Description

The invention relates to printing presses, in particular to printing presses for printing on curved surfaces of articles, preferably spherical or hemispherical, and can be used for printing images on ceramic or metal products.

A device for decorating products, which is mounted on a carriage mounted on a horizontal guide, a spring-loaded stamp head, a vertical stirring mechanism, a stamping head, mounted on a second carriage paint supply mechanism, a doctor blade and a drive 1, is known.

However, the known device is not sufficiently reliable in operation, due to the complexity of its design. In addition, the complexity of its setup associated with the selection and change of the profile cam of the drive mechanism of the ramming head is high.

The aim of the invention is to improve the reliability of the device by improving its design.

This goal is achieved by the fact that, in a device for decorating products, which is mounted on a carriage mounted on a horizontal guide, a spring-loaded stamp head, a mechanism for the vertical movement of the stamp head, mounted on the second carriage, the ink supply mechanism on the plate, the doctor blade and the drive mechanism the vertical movement of the stamping head includes two rigidly interconnected and with the second carriage of the copier mounted on a horizontal guide, placed on opposite sides of the carriage with a shtampelny head, two fixed stops installed in the end sections of the movement of the carriage's stamping head of the carriage for interacting with it, and two pairs of levers that are hinged together, the first lever of each pair being connected to the clamping head, the second one with a carriage bearing the stamp head, and the joints of the levers of both pairs are placed on opposite sides of the carriage with a stamp head for interaction with the respective copiers during the period of interaction and past the stops.

FIG. 1-3 shows the proposed device in the outgoing and working positions, summarizing the view; in fig. 4 shows a top view of the device; in fig. 5 - carriage with shtamp; in fig. 6 - the second carriage with a paint feed and squeegee; in fig. 7 - profile slide of the squeegee movement mechanism; in fig. 8 - the same, top view.

A device for decorating products comprises a frame 1 with a bracket 2, on

the actuator is fixed in the form of a power pneumatic cylinder 3, the movable rod 4 of which is connected to copiers 5. Between the copiers 5, a carriage 7 is mounted on the rail 6 mounted horizontally on the base 1 of the guide 6. The stamp head 8 with the die 9 is hinged between itself. the pairs of levers 10 are connected to the carriage 7. On the axles of the joints 11 of each pair of levers 10 are mounted rollers 12 mounted with the ability to interact with copiers 5, which, in turn, are rigidly connected to the second carriage 13. On the latter are placed paint supply mechanism 14 and squeegee 15,

5 which, through a system of levers 16, is connected to a profile slide 17. A cam 19 is installed with a spring 20 on the axis 18 to provide reversal. On the side walls of the bracket 2 there are adjustable stops 21 and 22 and end switches 23 and 24 of the drive control unit (not

shown). The device also has a table of 25

for products 26 and cliche 27 for stamp 9.

Pivotally coupled pairs

The levers 10 of the mechanism for the vertical movement of the stamp head 8 have leading 28 and driven 29 links associated with the stamp head 8 and the carriage 7, which also has protrusions 30 for changing the position of the levers 10.

The movement mechanism the squeegee has

0 rollers 31 located on the lever 32 of the system of levers 16, which can run around the lower plane 33 of the cheeks 34 of the profile slide 17. The lever 35 of the indicated mechanism can move in the vertical grooves of the carriage 13.

The device works as follows.

When moving the stem 4 to the left (the copiers 5 move the carriages 7 and 13 to the left. In this case, the paint supply mechanism 14 applies paint to the tongue 27, and the blade 15 removes excess paint from the tongue 27. The carriage 7 moves until it touches the stop 21, and the stamp 9 rises to position "Above the plate. With the further movement of the stem 4 to the left, its force through the copiers 5 and the rollers 12 is transmitted to the pivotally interconnected levers 10, changing their position. The stamp head 8 moves in a vertical plane downwards, pressing down on a cliché 27. At the contact system of levers 16 with kul chkom last 19 is rotated on the axis 18 and the squeegee 15 moves vertically up to the surface profiled slides 17 which holds the doctor blade 15 in the upper position until the end of retrace. Spring 20

5 returns the cam 19 to its original position. Upon contact of the copiers 5 with the end switch 23, the stroke of the rod 4 is reversed. The stamp 9 under the action of

the springs move in a vertical plane upwards until the rollers 12 touch the opposite surfaces of the copiers 5, after which the carriage 7 begins to move in the horizontal direction until it contacts the stop 22. The stamp 9 takes the "Above product" position and moves in a vertical plane downwards. The paint 9 is transferred to the marked product 26 mounted on the table 25.

When the carriage 13 is moved to the left (Fig. 2), the rollers 31 roll around the lower plane 33 of the cheeks 34, the squeegee 15 under the action of the springs presses the tongue 27 against the surface and removes paint debris from its surface. The presence of compensator 36 makes it possible for the squeegee 15 to rotate on the axle. The lever 35 can move in the vertical slots of the carriage 13, thereby ensuring the optimum angle of inclination of the squeegee 15 to the surface of the cliche 27. When the rollers 31 contact the cams 19, the latter rotate on the axis when the rollers exit 31 from the contact zone, the cams 19 under the action of the springs contact the upper bearing surface of the profile slide 17. When the surface of the copiers 5 contacts the end switch 23, the course reverses, the copiers 5 and the carriage 13 ne move to the right, and the carriage 7 remains stationary until shtamp 9 under the force of the springs does not occupy the uppermost position, and the rollers 12 are not in contact with the internal profile of the copiers 5. The rollers 31,

Running around the surfaces of the cams 19, they are moved to the upper bearing surface 37 of the cheeks 34.

The change in position is made after the contact of the protrusion 30 of the carriage 7 with the stops 21 and 22.

Upon contact of the copiers 5 with the end switch 24, the cycle is repeated. Adjustable end switches 23 and 24 in contact with copiers 5 allow the vertical course of the chips to vary in a wide range.

The proposed design is much simpler than the known one, allows easy readjustment, and the print quality is not impaired.
