Description

[Detailed description of the invention] Industrial applications The present invention relates to a compressible sheet winding device.

Structure of conventional examples and their problems Conventionally, glass wool sheets, which are an example of compressible sheets, are rolled onto a winding shaft, fixed by wrapping with binding tape, and then pulled out from the winding shaft to produce a product. .

Then, in order to wind the glass wool sent by the conveyor onto a winding shaft, the winding shaft holds the tip of the glass wool sheet and rotates the winding shaft itself using a center winder method to obtain the desired winding diameter. After that, the glass wool sheet is rolled up until the end of the glass wool sheet, and then the remainder of the glass wool sheet is wound up at high speed by switching to the surf-swinder method. In the center winder method, the winding shaft is rotated in conjunction with an electric motor, and in the surf-swinder method, a surface roller that is linked to a drive motor is pressed against the surface of the roll portion of the glass wool sheet to wind the roll. The remaining portion of the glass wool sheet is then wound up. The Surf Swinder method is useful for applying appropriate tension to glass wool sheets and winding them into rolls at high speed. The binding tape is attached by winding the binding tape around the outer periphery of the rolled compressible sheet and thermally bonding it. In this case, conventionally, a heater was built into the surface roller (usually one of the two provided) as a means of pressurizing and heating the binding tape, and this surface roller was also used as a heat roller. , I had the following problem.
(1) Since the entire outer peripheral surface of the surface roller is heated, products with polysheet or aluminum foil laminated on the surface will melt and tear due to the heat.

(2) If the heater built into the surface roller (cartridge heater) breaks, the winding device must be completely stopped during the time required to replace it, reducing work efficiency. Furthermore, maintenance of the surface roller itself is extremely difficult.

(3) Although the binding tape only needs to be heat-bonded at its overlapping portion, because it is constantly heated by the surface roller, the entirety of the tape wound around the rolled glass wool sheet will not adhere to the product. This reduces the product value.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a compressible sheet winding device which eliminates the above-mentioned conventional drawbacks.

Structure of the Invention In order to achieve the above object, the compressible sheet winding device of the present invention has a compressible sheet winding device in which a predetermined length portion is brought into pressure contact with the surface of the rolled part of the compressible sheet rolled around a winding shaft, and is fed to the rolled part surface of the compressible sheet rolled around a winding shaft. The heat roll is equipped with a roller that winds up the remaining part of the compressible sheet by applying pressure, and a heat roll that heats the overlapping part of the binding tape wound around the outer periphery of the rolled compressible sheet that has been wound. , has a heating wall that surrounds the outer periphery of a hollow cylindrical body containing a heater and has a rounded shape at both ends in the width direction, and is applied to the roll-shaped compressible sheet around an axis parallel to the winding axis. It is held by an arm that swings toward and away from the binding tape, and is configured to press the heating wall body against and away from the overlapping portion of the binding tape.

Examples and effects Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 1, reference numeral 1 denotes a glass wool sheet transport conveyor, and winding shafts 3, 3 supported in a cantilever manner at both ends of a turret arm 2 are disposed opposite the terminal end of the conveyor. The winding shafts 3, 3 have open grooves 4, 4 cut in the axial direction from their free ends, and are linked to a drive motor (not shown) to enable rotation by one type of center winder. . 5, 5 indicates a pair of surf rollers, which are held at the free ends of a pair of intersecting arms 6, 6.

The armatures 6, 6 are mounted on a carriage 7 by a pair of shafts 8, 8 parallel to the winding shaft 3, respectively, so as to be able to swing toward and away from each other. Incidentally, the surf S rollers 5, 5 are interlocked with the drive motor 9 in order to carry out the surf S winder method. When one winding shaft 3 faces the terminal end of the conveyor 1, the tip of the glass wool sheet G is fed into the open groove 4 of the winding shaft 3, and from this state it is wound up by the center winder method. The shaft 3 rotates and rolls the glass wool sheet until it has a desired winding diameter. Next, a pair of surf S rollers 559 pressed against the lower surface of the roll winding portion start rotating, and the winding method is switched from the center winder method to the surf S winder method. Immediately before winding is finished using the Surf S winder method,
A binding tape 10 is sandwiched between the end portion of the glass wool sheet and the rolled portion, and then the binding tape 10 is
As a result of the feeding, the binding tape 10 is wound around the outer periphery of the rolled compressible sheet. The binding tape 10 is fed out from a tape supply device 11. The tape supply device 11 includes a support shaft 13 for the rolled tape 12, a feed roll 14, a feed conveyor 15, a cutter (not shown), etc., and its operation is controlled in accordance with the operation timing of the cutting machine for the glass wool sheet G. 16 is a heat roll.

As shown in FIG.
A heating wall 19 surrounding the outer periphery of the hollow cylinder 17 and forming a space 18 between the hollow cylinder 17 and the hollow cylinder 17 is fixed. A large number of pores are bored in the outer wall of the hollow cylindrical body 17 at a portion surrounded by the heating wall body 19 . Also, both ends 19A, 19 in the width direction of the heating wall body 19
A is configured in a rounded shape. The hollow cylindrical body 17 is rotatably attached to the support rod 22 via sliding bearings 21, 21 provided at both ends thereof. 23, 23 are positioning tools.

24 is a cartridge type heater, which is arranged in plural inside the hollow cylinder 17, and is supported by the support rod 22.
This is done by attaching it to the mounting bracket 25 via the mounting bracket 25.

The heat roll 16 is disassembled and assembled by pulling it out or inserting it into the support rod 22 in the axial direction with the positioning tools 23, 23 removed. In FIG. 1, reference numeral 26 denotes an arm, which rotates around an axis (not shown) parallel to the winding shaft 3, relative to the rolled compressible sheet 27 wound around the winding shaft 3. It is held so that it can swing toward and away from each other. The support rod 22 is attached to the swinging end of the arm 26 so as to be parallel to the winding shaft 3, and a pneumatic cylinder 28 is interposed between the arm 26 and the fixed side. The effects of the above configuration will be explained below.

As shown in FIGS. 3 and 4, the binding tape 10 wound around the rolled glass wool sheet 27 as described above is in a state in which its terminal end overlaps the middle part of the binding tape 10 over a certain angle. Become. Therefore, as this polymerization winding is started, the heating wall 19 of the heat roll 16 is expanded by the expansion of the pneumatic cylinder 28, as shown by the solid line in FIG.
If the heating wall body 19 is separated by the retraction of the pneumatic cylinder 28 as shown by the imaginary line in the same figure as the overlapping winding is completed, the binding tape 10 will be attached only to the overlapping part 10A. is thermally bonded, so there is no deterioration in product quality. Since the heating wall body 19 of the heat roll 16 has a curved widthwise end portion 19A, 19A, the heat roll 16 is highly versatile for binding tapes 10a, 10b of different widths. In other words, as shown by the solid line in Figure 5,
When thermally bonding the overlapping portion of the binding tape 10a that is narrower than the heating wall 19, both ends 19A of the heating wall 19
, 19A is pressed against the binding tape 10a, so thermal bonding is possible without any problem. Further, as shown by the imaginary line in the figure, when the overlapping portion of the binding tape 10b, which is slightly wider than the heating wall 19, is thermally bonded, the heating wall 19
When the glass wool sheet 27 is pressed against the rolled glass wool sheet 27, the sheet 27 is deformed against its elasticity, and both ends 19A, 19A of the heating wall 19 are connected to the binding tape 10.
Since the end portion of b is also pressed, there is no problem in heat bonding. Effects of the Invention As is clear from the above description, according to the present invention, the heat roll can be brought into pressure contact with or separated from the overlapping part of the binding tape wound around the rolled compressible sheet as needed. The binding tape can be thermally bonded only at this overlapping portion.

Therefore, unlike in the past, the binding tape does not adhere to the outer periphery of the product and degrade the product quality. In addition, since the heat roll is installed separately from the roller (surf roller) that feeds the rolled part of the compressible sheet, maintenance of the heat roll, such as a break in the heater, is required even while the compressible sheet is being wound. It becomes possible to perform replacement in such cases, and there is no need to stop operation. Further, the heat roll has heating walls having rounded ends, and the heating walls can contribute to thermal adhesion of the binding tape overlapping portion, so it is highly versatile for binding tapes with different widths.
