SU23212A1 - Device for automatic shutdown of core sleeve machines - Google Patents

Description

For automatic stopping of the sleeve machines, a device is proposed using a lever loaded with a spring, under the action of which, when the paper tape is broken, the said lever releases a spring-loaded slider, which is connected with a spring loaded and kept from moving the two shoulders with a heavy roller resting on the moving belt.

In FIG. 1 is a front view of the proposed fixture without a slider associated with the translation; FIG. 2 - the same side; FIG. 3 - the same, from above in a section; FIG. 4-side slider for translation; FIG. 5 view it from above.

In the cage 1 of the proposed fixture (Fig. 1-3), a lever 4 is attached to 5, connected by an end with a spring 20 and provided with a tooth for coupling with a pawl 6, a rotatable sleeve 8 on an axle 7 and a spring 19 attached, screw 16 holder 1. On the free end of axis 5, a double-arm lever 11, 12 is mounted, one shoulder 12 of which, fixed to the hub of the other shoulder with a screw 15, is provided with a roller 14,

sitting on the finger 13 of the shoulder and intended to act on the dog 6, and the other shoulder 11 on the finger III (Fig. 3) carries a heavy roller 9, which is kept from falling by a paper sleeve c. The lever 4 is connected with a pawl 26 (figs. 4 and 5), swiveling, on the axis 24 and pulled away to the opposite side of the cable (side 19, pressed by the screw 25 to the body) by means of a flexible cable - d, which bends around a series of guide rollers. 21. Inside the latter, a slider 22 slides, which is connected with the transfer of the drive of the machine and under the action of a spring 23, with one end attached to the slider and the other end with the help of a screw 24 to the housing 1, with the action of the spring the slider is designed to translate the translation for switching Maschiny with a worker at idle.

Before starting up the maschine, lever 4 is manually shifted from position av to position b (Fig. 1). In doing so, the roller 9 rotates the double-arm lever II, 12 and the roller 14 presses on the dog 6, thereby attaching it to the lever 4. The slider 22 also manually moves to the right, stretching the spring 23, and its tooth engages the dog 26 (Fig 4), by moving the slider 22 to the right, the transfer includes the ma on the working stroke.

In operation, roller 9 is held by a moving belt with a sleeve. As soon as the latter is broken, the roller 9, lowering, releases the pawl b, which by the action of the spring 19 moves to the abutment 3 and disengages from the lever 4. The latter, freed from the pawl 6, under the action of the spring 20 rotates from the position to a and , the cable d is taken along, thereby withdrawing the pawl 26 (FIG. 4) from engagement with the slider 22. With the last action of the spring. 23 moves to the right together with the transfer, the machine switches to idle and stops,

whereupon all the levers are again cocked and the roller 9 is placed on the belt c (Fig. 1-3).

The subject matter of the invention.

A device for automatic stopping of sleeve-mounted machines, characterized by the use of a lever 4 loaded with a spring 20, locked with a dog 6, also loaded with a spring and held. the tape is used for tensioning under the action of the spring 20 of the cable d, which opens the spring-loaded slider 22, associated with the translation.
