Description

The invention relates to machine tools for applying patterns to porcelain dishes by rolling the processed products along a fixed rubber seal (cliche) with paint applied to it. In the proposed machine, a rotating disk is used, located between rubber seals and equipped with spindles with devices for mounting and axial rotation of the dish to be processed while pressing it against the seal and spindles carrying rollers designed for applying paint on the cliché.

In FIG. 1 shows a side view of the machine, with a partial cut; FIG. 2 - view it from above.

On the circular rotating disk 1 there are two spindles 2 for setting the dishes and two spindles 3 for installing the rollers 4. The spindles rotate in the bronze bushings 5. At the upper end of the spindle 2 a wooden block b, the shape of which corresponds to the shape of the dishes, is mounted. At the lower end of the spindle 2, a drum 7 with varying diameter is tightly fitted. The device is as follows: six holes are drilled in the body of the drum along the radius, steel pins 8 are inserted into one. At one end they rest against the cone 9, and the other end into the split ring 10, which is pressed tightly against

pins 8. When screwing in a cone 9, the pins 8 are radially distributed and the ring 10 is evenly extended, i.e. the diameter of the drum 7 is increased. A flexible steel tape 11 is wound on the ring 10 in a square recess, one: the end of which is attached to the drum 7 and the other to the slider 12, for which the half ring 13 serves as a guide. The bottom wall of the slider 12 slides along the movable hoop 14, which does not allow it to go off the guide 13. In two opposite places of the hoop 14 there are two pairs of latches: one 15 is located according to the moment of the start of printing, holds the slider 12: at the time of the start of printing, and the other 16- at the end of printing; the tape is unwound. on drum 7, made it spin. This rotation is transmitted to the dummy b and, therefore, to the vessel that has been planted on it. When the drum 7 makes one turn, the latch 15 is recessed by the plate 17, screwed to the guide 13; the slider 12 is released from the engagement, the tape 11 is screwed back onto the drum 7. This continues until the slider 12 reaches the second latch 16. This distance exactly corresponds to, U, a full revolution of the drum. The rotation of the drum in this direction is communicated by the spiral spring 18 fixed by one

The END on the disk 1, and another, a steel cord 19, wound in the opposite direction (relative to the tape 11) on the neck and of the drum 7. On the other pair of spindles 3 rollers 4 are put on. They are driven in rotation from the pulley 20, mounted on the bottom spindle 3. A rubber ring 21 is put on the pulley 20, with which it touches the hoop 14. The roller 4 is attached to the roller 4 and the coil spring 23 is pressed against the second roller 22, having four recesses, holes in, communicated by small holes with a side surface. The paint is put into these wells, which, when turned into rollers 4 and 22, in thin layers, lies on their side surface. However, they receive the drive from the pulley 20, which, when the drive 1 starts turning, begins to roll along the hoop 14. Near the disc 1 there are two holders opposite in diameter, the device of which is in the following. Brackets are screwed to the wooden table — walls 24, on the vertical part of which there are guides, noth slots for the projections of the square 25. With the help of screw 26, the square 25 can be raised and lowered depending on how high it is to make an arabesque. On the horizontal shelf of the square 25, three screws 27 hold the box-shaped half-ring 28, and the rubber seal 29 is inserted into the Topos. The length of the seal 29 is equal to the circumference of the printed dish. The length of the semiring 28 is equal to the circumference and the smallest diameter. For longer, the seals 29 on the right side are made a retractable rail 30, which holds the end of the seals 29 out. With the help of three spiral springs 31, the half ring 28 is sent forward and produces a print of the pattern on the dishes when printed. On the left side of the square 25, there is a latch 32; when moving the half ring 28 backward, its end enters the recess on the half ring 28 and holds it, not allowing it to move forward. By pressing the other end of the latch 32, the half ring 28 is released from the engagement and is sent forward by the coil springs 31. It happens at that moment when

  -

the cup will approach the signet and begin to rotate. Turning off by pressing the latch 32 produces a plate 33 screwed to disc 1. Such a device eliminates the smearing of paint on the dishes at the beginning of printing.

On the proposed machine, two people must work, facing each other, each producing sa-ware printing: one on the right seal, and the other on the left. Work on the machine both boils down to the following: a cup is put on the block 6; After that, the worker, gripping the handle 34, turns the disk 1, the rollers 4 and 22 begin to rotate, the cup goes to the seal 29, the plate 33 presses the latch 32, the half ring 28 together with the seal moves forward and presses the cup. At the same time, the slider 12 locates on the latch 15, the dummy b, together with the cup, begins to rotate. When the cup makes a complete turn and the printing is finished, the latch 15, when the plate 17 is placed on it, releases the slide 12 from engagement. The drum 7 and the cup reverse the rotation (.4 turns) until slide 12 stops the second latch 16. Slider 12 is released when the cup moves away from the seal 29 and can rotate freely without touching the handle. her Following the cup, the seal 4 rolls the roller 4, leaves the paint on its projections and retracts the front end of the half-ring 28, sets it on the latch 32. Further work of the machine will take place in the same order.

The subject of the patent.
