SU27386A1 - Device for imprinting digital signs when marking the lining and the upper edge of the shoe - Google Patents

Description

The invention relates to machines for stamps in which the stamping drum is rotated after impact with a ratchet pawl. In the proposed accessory for the brand of the lining and the upper edge of the shoe, when it is necessary to apply the same digit on them, a ring with numbers is attached to the drum drum, which is turned with the help of a ratchet pawl and a roller in contact with the moving guide, with a movable guide. a spring and a pawed disc moved to it.

 The drawing shows a view of the proposed fixture for the front.

An additional ring / with figures, tightly connected to the ratchet 2, turned by the pawl 8 either after each drum beat, or after two beats, is attached to the drum drum. When digitally imprinting with each stroke of the adhesive drum, the special guide 5 for the roller 4 of the hammer 3 serves to turn the lever b; at the same time, the doggie 8 grabs the ratchet tooth 2 and turns the ring / to the next digit. If you need to print the numbers twice more, for roller 4 there is

there is still a guide P with a roller 10 at the end, attached to the rail / 7, movable in a horizontal direction (in the direction of arrow 12} and a pressing spring 13 to the cam disc 14. The latter is fastened to the ratchet 16.

In the first case, the mechanism works as follows. When raising the hammer B, roller 4 rolls along the guide, 5, turning the lever b around axis 7, while the doggie 8 grabs the ratchet tooth 2 and turns the digital ring 1 in this way. When lowering the hammer 3, the lever 6 by means of a spring (not shown in the drawing ) returns to the initial position and the dog S grabs the next tooth of the ratchet 2.

For the brand, twice the same digit of the roller 4 moves along its axis and becomes in the plane of the other rail 9, on the upper end of which there is roller 10.

When the drummer 75 is raised, the pawl catches the ratchet bar 16, fastened to the cam disc 14, and turns it 1/8 of a turn. So The roller 10 is alternately alternately against the projection, then against the trough of the cam disc 14; in the latter case, the spring guide 9 by the force of the spring J3 departs from the roller 4, and the digit change does not occur.

The subject matter of the invention.

A device for imprinting digital symbols when stamping the lining and the upper edge of the shoe using a stiffening drum, characterized in that an additional ring T with numerals is attached to the stiffening drum, for turning which, in order to imprint the same digit at two drum beats, serves as a guide 9 with the roller JO in contact with the buckle disc J4 and a guide rail // with the spring J3 for pulling the guide 9 from the rollers 4.
