Description

Rotators are already known to be printed on roll paper and provided with devices for tearing a sheet from a roll, a counter and a signal bell.

In the proposed rotator, a cutting device of a special design is used.

In FIG. 1 shows a general view of a rotator; FIG. 2-section on AB.

As can be seen from the drawing, the rotator consists of a wooden cylinder (drum) 7 rotating on axis 2 in racks 3 mounted on pedestal 4. The rarabane is covered with cloth sheath 5 soaked in paint using a brush until the installation of the stencil. The shell 5 is reinforced with two rods b, inserted into the 7ссфи .J6 recesses in the drum 7. To install the wax on the drum 7, there is a latch 7, which is a metal plate rotating on the axis 8 and pressed against the drum 7 by a spring. The trimming is applied to the thin fabric over the cloth 5. The drum is rotated by an electric motor using the knob P mounted on axis 2. The paper roll JO is mounted on the axis / 7, laid in the folding brackets 12, which rotate on the 13c pins retained in the folded

(27)

the position of the pins 14. The paper from the roll 70 is passed under the bottom of the drum / and pressed against it by the action of a spiral spring 75 pulled by a screw 76, a rubber roller 17 rotating at the ends of the qcH / 5 in the slots / 9: rocker arm 20 turning on the pins Screws 27-.

The cutting apparatus consists of an upper blade of the fixed knife 22 and a lower movable knife 23 fixed on the yoke 24, turning on the pins-screws 25. The movable knife 25 along the edges is provided with openings through which the narrow ends of the 24 blade pass, and springs pressed to the lateral processes 22a of the upper stationary knife 22. In the processes 22a, longitudinal slots 226 are punched in which the narrow ends 24a of the rocker arm move 24. The yoke 24 with the knife 23 is held in the lower position by the spring 26.

Two eccentrics are fixed on the drum 1, one fixed 27 and another movable 28 fastened to the pointing arrow 29. The arrow 29 is set depending on the length of the original to be duplicated, and is fixed in the desired position by a knurled nut 30 that pulls the screw 31 into a notched the plate 32 to the plate 34 fixedly mounted on the drum / screws 33, also jagged from the side of the butt with the plate 32; A screw 55 is put on the screw 3J, which, when screwing the nut 30, is pulled from the outside to the plate 34, with the lower side of which is attracted to the serrated side of the plate 32, which fixes the arrow 29 and the movable eccentric 28 connected to it in the desired position. Roller 36 rotates on sleeve 35. On C5SI 2 of drum 1, strap 37 walks, in its upper part there is an elongated hole 37a, with which the strap fits on axis 2, and at its lower end there is another hole for connection with a 3S pin fixed on the right end rocker arm 24. Roller 39 is reinforced on the bar 37. The upper edge of the original (stencil) is laid between the drum 1 and the latch 7 ,. When rotating drum 1 with roller 9, the roller 36 of the arrow 29 mounted against the lower end of the original comes to the lever 40, which is fastened with a screw on the process of the pedestal 4 bent up, the eccentric 28 with its protruding side 28a presses the roller 39 and pushes the bar 37 downwards, thereby retraction a paper press roller (7 from the drum), which results in stopping the feeding of paper from the roll / 0. The roller 39, reaching the lever 40, pushes the last 40a s-cage, which with its other end 406 rises up and presses the lever 4, mounted on the right end of the rocker arm 24, turning on the pins 25, thus lifting up the arm 24 bearing 23 which, before reaching the upper | fixed knife 22, cuts off the printed paper 0a.

At the upper end of the bar 37, a pin 43 is fastened, which engages a lever 44, mounted on a rack 45 and able at its other end the doggie 46, which is. Mri Oskun14 and the bar 37, captures the digital wheel 47, which has one hundred divisions and with each new chottisk turns it one division. The arrow 48 indicates the number of prints obtained, and the other arrow 49, using the handle 49a, is set against a number indicating the number of copies to be reproduced. When the arrow 49 being installed on the desired number of impressions, reaches the end of the hammer of the bell 5 /, the latter will ring, signaling the termination of work.

The subject matter of the invention.

A rotator for printing on roll paper provided with a cutting device, a counter and a signal bell, characterized in that its cutting device consists of an upper fixed knife 22 and a lower movable 23 fixed on the yoke 24, equipped with a spring-loaded lever 47, driven by the end 406 of the lever 40 impacted by roller 39 reinforced on a bar 37.
