Abstract

PURPOSE:To reduce the time for replacing rolls by disposing a suitable number of engaging claws capable of rising and setting in the radial direction of a tube with the movement of a moving member, and providing an engaging piece always projecting in the radial direction of the tube on the other moving member. CONSTITUTION:As an engaging piece 34 of a roll holder 22 always projects over the peripheral surface of a hollow support tube 24, at the time of installing a roll body 14, the end portion of the roll body is brought into contact with the engaging piece 34 to be prevented from positioning outside the moving range of moving members 28, 30. When a reverse screwed shaft 26 is turned by a handle 46, the moving members 28, 30 approach each other, and simultaneously the moving member 28 moves through a through hole of a sleeve 48, so that an engaging piece 32 is expanded by a taper portion 28b. When the reverse screwed shaft is further turned, the sleeve 48 moves with the moving member 28, and inclined portions 32a, 34a enter an opening portion of a core 16 of the roll body 14 to fix the roll body 14 to the hollow support tube 24.

Prior Art Single webs of long paper, films, metal foils, etc., composite sheets such as laminated films (hereinafter simply referred to as "webs")
A roll body made by winding a material (called ``synthesis'') around a hollow core is widely used in various industrial fields for various purposes. For example, in a bag making, filling and packaging machine, a roll body made by winding up a synthetic resin web as a packaging material is loaded into a predetermined position within the machine frame, and the web is continuously fed out to form a bag body. Various pillow packaging bags are manufactured by filling the bag with articles. In this type of packaging machine, when the original roll is used up, it is necessary for an operator to replace it with a new roll.

Next, a mechanism for expanding the locking pawl 32 that is attached to the movable member 28 will be explained. As is clear from FIGS. 1 and 2, the locking pawl 32 is composed of a plate material having an inclined portion 32a, a contact portion 32b, and a sliding portion 32c, and is rotatably pivoted to the sleeve 48 at its base. has been done. That is, as shown in FIG. 1, a total of three slits 5 are formed on the outer peripheral surface of the sleeve 48 at intervals of 120° in the circumferential direction.
4, and by inserting the pin 56 through the slit 54 and the base, each of the locking pawls 32 is rotatably pivotally attached to the sleeve 48. Ru. Further, the three locking claws 32 include the locking claws 32 .
so that it does not always protrude from the long through groove 36 of the hollow support tube 24.

The sleeve 48 is inserted into the hollow support tube 24 while being slidably fitted onto the movable member 28. At this time, two annular grooves formed on the outer periphery of the sleeve 48 have grooves.
O-ring 58 that can contact the inner wall of the hollow support tube 24.
58 are respectively fitted, and at the beginning of the movement of the moving member 28,
The sleeve 48 itself is subjected to resistance due to friction between the circle ring 58 and the inner wall of the tube, so that movement in the axial direction is restricted. When the movable member 28 moves in a direction approaching the sleeve 48 whose movement is restricted, the locking pawl 32 engages the tapered portion 28b of the movable member 28.
The sliding contact portion 32c has settled down.

Furthermore, three locking pieces 34 are fixed to the other moving member 30 as described above. This locking piece 34 is formed with an inclined surface 34a and a vertical surface 34b, and the end of the core 16 of the roll body 14 is pressed by the vertical surface 34b. Further, since the locking piece 34 always protrudes from the circumferential surface of the hollow support tube 24, when the roll body 14 is inserted into the hollow support tube 24, the vertical surface 34b
This serves as a stopper for 4.

In the roll holder 22 according to the present invention, the roll body 14
When it is removed, there are three locking claws 3 as shown in Figure 2.
2 does not protrude from the circumferential surface of the hollow support tube 24, so that the roll body 14 can be easily inserted into the hollow support tube 24. In this case, the locking piece 34 arranged in the direction of the outer insertion of the roll body 14 always protrudes from the circumferential surface of the hollow support tube 24, so that the end of the roll body 14 will eventually be connected to this locking piece. 34 and is prevented from moving, thereby preventing the movable members 28, 30 from being located outside the range of movement.

After the roll body 14 is inserted into the hollow support tube 24, the handle 46 attached to the end of the reverse threaded shaft 26 is manually operated to rotate the reverse threaded shaft 26 in a predetermined direction. .30 in a direction closer to each other. At the beginning of the movement of the moving member 28, the sleeve 48 fitted into the moving member 28 does not move due to the frictional resistance between the O-rings 58, 58 and the inner wall of the hollow support tube 24, and does not move through the through hole of the sleeve 48. Only the moving member 28 moves in the axial direction.

Then, the inclined portions 32a and 34a formed on the locking claw 32 and the locking piece 34 are inserted and fitted into the opening of the winding core 16 of the roll body 14 as the moving member 28.30 moves. Furthermore, a pressing force in the axial direction acts, and as shown in FIG. 4, the locking pawl 32
The contact portion 32b and the vertical portion 34b of the locking piece 34 are pressed against the open end of the winding core 16, and the roll body 14 is reliably loaded and fixed to the hollow support tube 24.

Next, when removing the roll body 14, the handle 46
By rotating in the opposite direction, the surface moving member 28.3
0 are moved away from each other. At this time, the locking pawl 32 is always urged in the closing direction by the O-ring 60, so as the movable member 28 moves, it slides into the hollow support tube 24 while slidingly contacting the tapered portion 28b of the movable member 28. He will die. Therefore, the force pressing the roll body 14 in the axial direction is released, so that the roll body 14 can be easily removed.

Note that the sleeve 48 fitted into the moving member 28 is attached to the O-rings 58, 58 at the beginning of the movement of the moving member 28.
Because of the frictional resistance, it does not move inside the hollow support tube 24. However, when the moving member 28 moves further, the U-ring 50 attached to the moving member 28 comes into contact with the end of the sleeve 48 and moves in the hollow support tube 24 in the same manner as the moving member 28.

According to the roll holder according to the present invention as described in detail,
Unlike conventional holders, it does not require a series of complicated operations such as removing the conical block and aligning the central axis of the inserted roll body every time the roll is replaced, and even someone without particular experience can use it. This allows for easy roll replacement work. Furthermore, even when the width of the roll body is changed due to an order change, the center of the web in the feeding direction can be automatically determined, and the time required for replacing the rolls can be reduced. Therefore, the time during which production line operations are stopped can be minimized.

生産効率を向上させることができる等の利点を有する。It has advantages such as being able to improve production efficiency.
