Description

The present invention is a further development of the appliance for a trowel machine for automatic removal. In the present proposal, in order to further increase the efficiency of the machine, drying the mechanical lifting of the dies, the ejection of the canvas is associated with this lifting, and the filling of the canvas is performed by special drivers, rather than a roller, to avoid deformation of the canvas during its operation. The fixture is equipped with a mechanism that sets in motion the canvas carriers and is self-switching during the process of filling the canvas. In addition, another device was used to refuel the rolling pin and hold it on the stand associated with the operation of the cut-off lever.

In FIG. 1 shows schematically a general view of the machine equipped with the proposed device, and FIG. 2-part device.

The shut-off lever 1 is hingedly attached to the pull 2. When the shut-off lever is raised, the upper end of the hook turns the hook 5, which frees

rolling pin. Lastly, the guide 7 is fed to the place where the web is rolled.

The process of the work of the device is divided into several points and is connected with the work of the cut-off lever. Turning on the cut-off lever I the machine starts up, with the first turning on manually, after blowing-automatically. Together with the lifting lever 1 t hectare 2 goes up and the end of its 3 stands for the edge of the rack 4, delaying the laid-on it rolling pins. With lifting, the hinged hook 5 comes into operation, which, when lifting, moves beyond the edge of the rack, rotates about the axis 6. the end is removed, but the hook 5 protrudes, and the rolling pins roll to a new obstacle. The next time you turn on, the same thing happens, but the rolling pin, which up to this point was delayed by a hook 5, rolls along the rack, switches to guide 7, lowers it with its weight and, supporting the canvas thrower 8, lowers

to your place; A friend of the same rolling pin will be held up by the end of 3.

With rjycKOM, the machines start vras, plush shafts on the upper shaft, carry gear 9 on themselves, transmit 10 vras, via the intermediate gear, enne gear 11 with the eccentric 12 fixed on it. On the eccentric profile rolls the roller 13 fixed on the lever 14 to the end of which sits gear 15, meshes with the gear 16, which sits on the shaft, which turns the levers 17 for filling the canvas. One turn of the gear with the eccentric corresponds to the period of filling the canvas. At the beginning of their movement, canvas holders move at the speed of the produced canvas, a little off until the rolling pin is delayed, allowing the 5th end of the canvas to go under the rolling pin, then quickly moving forward to the rolling pin, stopping again, waiting for the end of the canvas to come out and ending quickly the canvas on the rolling pin, again stopped, allowing the canvas to roll, and retreat to its original position. In order for the charging process not to be repeated immediately, gears 10 and 11 must be open, for which shaft 18, on which gear with eccentric rotates, can be horizontally moved in a special slot in the cheek. This misalignment is communicated to the shaft by the projecting tooth 19 (FIG. 2) of the pinion 11, which, when engaged with the gear 10, moves the shaft 18 by the amount of the protruding tooth. In this extreme position, the shaft will be locked by the dog 31, which with its protrusion will sink into the protrusion of the undercurrent of the shaft 18, and the spring 21, remaining stretched, will not be able to clutch until the doggie releases the bearing. During the further process of the canvas, not a single detail comes into play; Only a few seconds before the cut-off, there comes a moment of disengaging the brake pulley to freely raise the combs. Bleeding produces gear 22, fixed on the square 23, screwed to the brake pedal pad. The gear 22 has two tall (not profiled) teeth 24; when these teeth engage with the cut-off gear 25, the latter, unable to shift, causes the gear 22 to move downward by the size of the advancing teeth, which is sufficient to deflect the brake and release the cheek.

When the cut-off (falling cut-off lever) is the separation of the gears 26 and 27, and therefore, stop flatting shafts. At the same time, the friction pulley 28, which sits on the same shaft as the gear 26, descends to close with the friction 29, which sits on the shaft to raise the combs. The continuous rotation of the clutch 28 causes the combs to rise, which, when they meet their levers 33, will lift them, turning them around the shaft 18. The lever 33 is connected to the canvas 8 by the spring 34, which pushes the canvas to the trough as it rises. The cut-off lever 1, the pad, carries away the pu 30, which presses the nuts of the pawl 31 with nuts, turning it on the axis 32, causing the head to rise, releasing the shaft 18, and the action of the spring 21 causes the gears 11 and 10 to close. canvas paws 35, host canvas, lie at the bottom of the trough; when the cut-off lever falls, the system of levers 36-37 turns 38 at a certain angle and lifts the paws 35. The ejected canvas, rolling on the raised paws, lowers them with its weight and, lifting the lever 1, turns the machine into operation. The length of the trough is designed for two canvases. Thus, a worker servicing Kvashin may not within 10-15 minutes approach the front of the machine, which allows an increase in the number of machines serviced by one worker.

The device refills the rolling pin, the canvas and pushes the worked canvas; the worker’s share is left to attach the bar and, having taken out the rolling pin, put it on the rack 4, and he can do this operation at any time during the work of the second or third canvas.

The subject matter of the invention.
