Description

one

The invention relates to the production of rubber products and relates to a device for winding a tape on a cylindrical piece, for example electrical tape on a gas mask socket.

A device for winding a tape on a cylindrical part is known, comprising a mandrel mounted in the housing, a device for clamping the tape, a cutting mechanism and a tape cassette 1.

However, in this device, the work on the tape ladder is not automated, which limits its technological capabilities.

In order to expand the technological capabilities by winding electrical tape on the eye socket of the gas mask, the proposed device is equipped with a device for moving the tape cassette around the mandrel, containing a drive copier with an automatic arrow, the axis of which is set eccentrically relative to the axis of the mandrel, and the tape cassette is fixed on the front side of the copier, moreover, the device for clamping the tape is mounted on the axis of the copier and has a copy roller in contact with the copier and an automatic arrow.

The device for clamping the tape is made of a spring-loaded rod installed in the guides and carrying the copy roller at one end and the clamping

a fork in contact with the mandrel and connected to the other end of the bar by means of a dog.

FIG. 1 shows the proposed device, a general view; in fig. 2 - section aa

in fig. one; in fig. 3 - drive copier with

automatic arrow; in fig. 4 - a device for clamping the tape.

The device contains mounted in

package 1 sending 2; an attachment 3 for clamping the tape (fig. 4), consisting of a clamping fork 4 in contact with the sore 2, a pawl 5 fixed on the axis 6 in the guides 7, a spring 8 and a copy roller 9 fixed on the movable spring-loaded shank 10. Direction The 7 clamping devices are fastened on the plate AND, on which the mandrel 2 is also fastened. The cutting mechanism has knives 12. The plate 11 is fixed fixed on the axis 13, mounted: in the housing 1.

The tape cassette 14 is fixed on the front side of the drive copier 15 with an automatic arrow 16 and a flag 17 (FIG. 3).

The tape is tucked into guides 18 located near the cassette 14 (Fig. 1). The guides consist of two rollers, pressed towards each other and spring-loaded against the stop so that the free end of the tape is 15-20 mm long. Axis of the drive copier 15

installed in the housing eccentric relative to the axis of the mandrel 2.

The cassette movement device consists of an air cylinder 19, a gear rack 20, a gear 21 carrying the pawl 22, a ratchet wheel 23, and a band brake 24.

The device is closed by a panel 25 having a window against the mandrel 2 (Fig. 2 and 4).

During operation, a gas mask socket 26 is installed in the window of the panel 25, which is centered on the mandrel 2. When the pneumatic cylinder 19 is turned on, the rail 20, gear 21, the ratchet wheel 23 and the driving cam .15 make two turns. First, the copier brings the tape cassette to the eye socket, and the free end of the tape rests on the eye socket. At this moment, the copier 15 runs onto the roller 9, switching it to the inner treadmill 27 of the copier. The rod 10 transmits movement to the dog 5, which presses the free end of the tape with a fork 4. Upon further rotation of the drive cam 15, the first tape layer is wound from the cassette 14 to the gas mask socket.

Prior to operation, the clip 9 of the clamp assembly is on the outer treadmill 28 of the copier 15. In the initial position, the automatic arrow 16 closes the window in the treadmill 27. When rolling for the first time, the roller 9 switches the automatic arrow 16 and the window in the treadmill opens. When the copier 15 rotates further, roller 9, through the opened window, goes to the upper position on the outer track 28 and, by moving to the ledge of the arrow 16, switches it to the initial position. As a result, the tape lies on the gas mask socket of the second layer.

After the tape is cut, the eye socket of the gas mask 26 is removed from the window of the panel 25, the plug 4 slides out, and the dog 5 is thrown off by the spring 8 to its original position.

The extreme position of the tape cassette is such that after the cut, a free end of 15-20 mm is left. The remaining end of the tape on the eye socket of the gas mask does not need to be rolled down, since the clip is put on and pressed in from above.
