Description

The present invention has in mind the reduction of the time for changing a used reel to a new one.

In the schematic drawing of FIG. 1 is a front view of the proposed fixture with a partial transverse section; FIG. 2 - side view with that reel; FIG. , 3 - side view of the put on reel; FIG. 4 is a view along arrow A of FIG. 2

The proposed device consists of a roller 5, on which a pulley is mounted with three protrusions 7, 8, 9 (Fig. 1, 2 and 3), in the slots of which pins 10, 71 VI 12 with rollers 75, M and / 5 are placed. On the axial sleeve J6 of the pulley b, a switch / 7 is placed, having a conical lift at the end.

When the switch is on the sleeve / b in the extreme left position, the pins W, 11 and / 2 under the pressure of the springs 18, 19 and 20 are on the trigger and their upper ends are hidden below the rim 6. The switch 17, under the pressure of its spacer springs 21 , 22 and 23, tends to move to the right (Fig. 3), but the pawl 24, dropping into the slot 25 of the axle bushing 16, holds it in the leftmost position (Fig. 2).

The action of the device is as follows. The worker servicing the machine, putting the reel on the pulley 6 (Fig. 2), presses the finger on the dog 24 and thereby removes it from the socket 25 of the axial bushing. The switch 17, freed from the dog holding it, moves under pressure of its springs 18, 9 and 20 to its extreme right position, and the pins 10, 11 and 12, lifted by the cone of the switch, extend beyond the rim and enter the coil ring, centering its so around the rim of the pulley (fig. 3).

To remove the reels from pins 10, 11, and 12, the female worker pushes the switch to the left until the pawl 24 drops into nest 25 again and pins down.

The subject matter of the invention.

A device for securing paper reels in sleeve milling machines, characterized by the use of a pulley 6 provided with pins 10, 11 and / 2, which are pushed under the action of the rollers 13, 14 and 15 of the conical part of the spring-loaded switch 17, which is held out of position by the dog 24.
