SU21008A1 - Safe device for starting roving and belt machines - Google Patents

Description

The invention is intended to prevent accidents that occur on roving and belt carts when the machine is started by the workers on the 1st side without warning the driver on the opposite side, this is applied on one side of the barbed arm, which is articulated with the conversion fork and the coupling removable with a spring stitch; a Christmas tree, which is derived from the working position by means of a rod on the other side of ME. At the same time, the inclined teeth of the pant allow the belt to freely move to stop, but to start it up requires coordination with the worker on the other side, who must be free in advance.

In FIG. 1 depicts a chagichno roving machine with the described device (side view); 1G 2 - the device itself (also an eye-catching sight).

The rod 6 with the grooved rollers 7 is engaged by means of a square 5 with a snap 2, which enters the box 9, which is attached to the frame of the car from the front horons. Through the holes in the walls of the box 9 passes the bar 1 with ngklonzyubtsami

from one side into the tube 10 and pivotally connected to the end with the lever 14, acting on the conversion fork of the machine. The spiral 3, placed inside the tube 4, presses the latch 2 to the rod 1, which moves freely to the left (according to the drawing), causing the latch 2 to be raised and lowered under the pressure of the spring; this is how the machine stops. But the start-up of the machine cannot be made only from the front, since the latch 2 prevents the movement of the rod 1 to the right (according to the drawing), i.e. It does not allow the transfer to the working pulley, and only when turning one of the grooved rollers 7 from the back side, the pivot pin 6 lifts the angle lock 5 through the square 5, which releases the rod 1, which can use the lever 14 to move the fork to the working stroke. FIG. Figure 1 shows rods 11 and 12, which are usually used on different sides of the machine for shifting the plug 13 in the same way as for starting and for stopping the machine.

The specified device can be installed and tape machines. with the replacement of the latch 2 lever, liberated. mm corrugated roller. The subject of the patent. A safety device for starting roving and belt machines, characterized in that, in order to protect against starting without warning, working on the opposite side of the machine, a rod 1 is used that is pivotally connected at one end with a belt outlet and is fitted at the other end with teeth. the latch 2 is pressed to the rod 1 by means of a coil spring 3 located inside the guide tube 4 and put on the latch 2, which latch is connected by the square 5 with the rod b located on the opposite rod 1 to the side of the machine and serving when turning the rollers 7 to raise the latch 2, in order to release the rod 1.
