Abstract

The invention makes it possible to improve the usability of the device, increase the reliability of fixation of the material at the initial time of winding and facilitate its release when removing it from the reel. The device comprises a drive with a coupling, drive and driven shafts 13, 18, a winding reel containing a central shaft 1 and movable strips 4 along the axis of rotation of the shaft 1. The flanges 2 with radial grooves are rigidly fixed to the central shaft 1 of the reel. In the grooves installed mobile strips 4, the ends of which are made bevels. The bevels are in contact with tapered stops 11, 17 mounted on the drive and driven shafts 13, 18. On the tapered stop 11 of the drive shaft 1, longitudinal grooves are made into which the end surfaces of the movable strips 4 enter their bevels. In addition, the central shaft 1 is provided with a pin 8, the free ends of which enter the slots 7 made in one of the movable bars 4. The free ends of the pins 8 are bent and directed with a tip towards the axis of rotation of the reel. In order to increase the efficiency of detaching the wound material and moving the movable bars 4 in the grooves of the flanges 2, the movable bars 4 and the central shaft 1 can be additionally interconnected by means of springs 10. 5 Il.

(54) DEVICE OF THE DAY OF WINDING LONG-DIMENSIONAL MATERIAL ROLL

(57) The invention allows to improve the usability of the device, to increase the reliability of fixing the mat. rial at the initial moment of winding and facilitate its release when removing

from the reel. The device includes a drive with a coupling, drive and driven shafts 13, 18, a winding reel containing a central shaft 1 and movable planes located along the axis of rotation of the shaft 1 and 4. The flanges 2 with radial grooves are rigidly fixed to the central shaft 1 of the reel. In the grooves installed mobile strips 4, the ends of which are made bevels. The bevels are in contact with the tapered stops 11, 17, mounted on the drive and driven shafts 13,18. On the cone support 11 of the drive shaft 1, longitudinal grooves are made into which the end surfaces of the movable strips 4 enter with their bevels. In addition, the central shaft 1 is provided with pins 8, the free ends of which enter the slots 7,

made in one of the movable bars 4. The free ends of the pins 8 are bent and directed with a tip towards the axis of rotation of the reel. To increase the efficiency of unhooking the wound

The invention relates to equipment for winding long materials, namely, drums or reels used for winding long materials into a roll.

The purpose of the invention is to increase the convenience of operation.

FIG. 1 shows a device for winding a web into a roll, general view; in fig. 2 is a section A-A in FIG. 1 in FIG. 3 is a section BB in FIG. one; in fig. 4 — node I in FIG. one; FIG. 5 is a sectional view B-B in FIG. one.

The device consists of a reel containing a central shaft 1 with rigidly fixed flanges 2 fitted with radially arranged pins 3 and 3 in which there are movable strips 4 with speeds 6 made at their ends 5, and in the middle part one of the slats has slots 7 in which the pins 8 with the tip 9, which are bent in the direction of the axis of rotation of the central shaft 1, enter, along the ends of the central shaft 1 there are springs 10 fixed to the movable strips 4. The reel is installed with one end on conical up Re 11 with grooves 12 of the drive shaft 13, mounted in the housing 14 on bearings and ending with an asterisk 15 ,. connected by a chain drive with a drive 16 having a coupling coupling.

The second end of the reel rests on

the conical stop 17 of the driven shaft 18, screwed through the thread 19 into the housing 20, mounted on the base-.

NII 21, on the driven shaft 18 set

A flap handwheel 22 with a latch 23, with which the bobbin is fixed on the conical stops 11 and 17 at the beginning of the winding of the web 24. To ensure free rotation, the conical stop 17 is mounted on the driven shaft 18 in the Rolling bearings.

The device works as follows.

material 1a and movement of the movable bars in the grooves of the flanges 2 movable bars 4 and the central shaft 1 can be connected to each other through springs 10. 5 or more.

A hand reel is inserted at one end with ends 5 with bevels 6 into the grooves 12 of the cone stop 11, and the second end of the reel is pressed with the cone stop 17 by means of the handwheel 22. In this case, the bars 4 occupy the uppermost position in the grooves 3 and the springs 10 are stretched.

In this position, the pins 8 with their pointed ends emerge from the props, recesses 7 of the bar 4. The web 24 winds around the bar 4 with the recesses 7 and clings to the pins 8. Rotation of the reel manually winds several turns of the web 24, Turning on the drive coupling 16 rotation through the chain transmission is transmitted to the sprocket 15 of the drive shaft 13 and through the grooves 12 on the conical support 11 is transmitted to 5 strips 4. The process of winding the web 24 takes place.

After the winding is finished, the rotation of the reel is stopped by turning off the No. of the driver 16.

By rotating the handwheel 22, the conical stop 17 is retracted to the extreme position, freeing the reel, while the movable strips 4 under the influence of the springs 10 move in the slots 3 to the I axis of rotation of the reel, reducing its outer size. Slats 4 with JMH 7, moving to the axis of rotation of the reel, with their slots 7 cover the pointed ends of the tongues 8, pressing the end of the wound web 24 hooked onto the pins x 8 and automatically removing it from the pins 8. After that the wound roll is easily removed from the reel. Then the cycle of operation is repeated.

The use of the proposed device will reduce the metal structure by simplifying the design of the reel and drive; simple means to solve the problem of fixation on the reel of material in the initial period of winding and unlock it when removing it from the reel; reduce the complexity of manufacturing the device due to the fact.
