Description

Sheet winding device

The present invention relates to a sheet winding device for continuously winding strip-shaped sheets such as resin sheets.

Resin sheets are generally manufactured by extrusion molding, and there are: when they are continuously extruded from the extruder that performs the extrusion molding, they are cut to a specific length to form a product; and they are rolled in a strip shape and later Steps that receive processing such as printing on the surface to form a product. In the production step of the latter product, at least one sheet winding device that continuously winds the sheet supplied from the upstream side to the reel mounted on the outer circumference of the winding shaft is provided. Moreover, as the sheet winding device, a rotary table sheet winding device is often used, which is equipped with a turntable mechanism that integrates two winding shafts and a reel mounted on each of them to roll the sheet. Switching between the take-up and reel position and the reel reel replacement position can continuously rewind the sheet without stopping the production line for reel replacement.

In the above-mentioned rotary table type sheet material winding device, there is the following rotary table type sheet material winding device, namely: the turntable mechanism is activated at the point when the winding shaft at the winding position has taken up a specific amount of sheet material, And send the winding shaft of the winding position to the replacement position, and in the replacement position, send the winding shaft with the new reel installed to the winding position, and set it to the winding preparation state, when in the winding position After the sheet is cut in the vicinity, the cut end of the upstream side of the sheet is brought into close contact with the reel at the reeling position by the winding unit, and the reel shaft at the reeling position is rotated integrally with the reel, thereby , The sheet is continuously wound to the reel (for example, refer to Patent Documents 1 and 2).

In addition, the sheet winding devices proposed by the above-mentioned Patent Documents 1 and 2 all have relatively large restrictions on the arrangement of the components, and the components of the winding unit are only provided at either of the upper and lower positions of the sheet transfer. By. Therefore, in the case where the continuously supplied sheet is divided and wound into a plurality of rolls, for example, in the middle of the sheet production step, the temporarily wound sheet is re-rolled for printing processing, etc. In the case of multiple reels, it is not possible to switch between forward winding (before and after rewinding, the winding direction becomes the same winding method) and reverse winding (before and after rewinding, the winding Take the direction to become the opposite winding method). In this case, if switching between forward and reverse winding between rolls, the following operations are required, namely: stop the production line and reverse the installation direction of the roll on the side of the sheet unwinding device.

In contrast to this, the applicant of the present invention has developed a sheet winding device with the following structure, namely: as a winding unit, a pair of guide mechanisms having a pair of upper and lower guide mechanisms for connecting/separating the reel relative to the winding position is adopted , In the rewinding preparation state, make each guide mechanism of the winding unit approach the reel at the rewinding position, press the sheet against the reel with one of its guide mechanisms, and cut the sheet on the downstream side of the guide mechanism The cut end of the upstream side of the sheet is pulled back to the winding position, and the winding shaft of the winding position is rotated integrally with the reel, thereby sending the cut end of the sheet to the other guide Between the citation mechanism and the reel (Invention Patent Application No. 2018-71384).

According to the above-mentioned structure, when the continuously supplied sheet is divided and wound into a plurality of rolls, the two winding shafts with rolls installed can be exchanged between the winding position and the replacement position only by appropriate selection. The operating direction of the turntable mechanism at the time can be easily switched between the forward winding and the reverse winding between the reels.

[The problem to be solved by the invention]

In addition, in the production step of the resin sheet, when the produced sheet is a harder sheet or a thicker sheet, the sheet reeled by the sheet reeling device produces stronger Curl wrinkles, when the roll on which the sheet is wound is installed in the sheet unwinding device of the next step, and the processing of the next step is started, a bad condition caused by the curl wrinkles of the sheet may occur. Therefore, according to the type of the sheet, etc., in order to reduce the curling and wrinkles caused by the sheet winding device on the sheet, it is required to make the outer diameter of the roll larger than the previous size.

However, in a general sheet winding device, if you want to switch the used reel to a reel with a different outer diameter, it is necessary to change the overall arrangement of the winding unit that surrounds the reel. The disassembly and assembly operations of the various components of the winding unit, etc., greatly reduce the operation rate of the production line, and generate a large work load. In view of this problem, the same applies to the sheet unwinding device described in the aforementioned invention patent application No. 2018-71384.

Next, the sheet winding operation of the sheet winding device to the reel 15 at the winding position will be described. In the case where the sheet S supplied from the upstream side is continuously wound from the upper surface side of the reel 15 (hereinafter referred to as "up-winding"), first, the upper and lower winding units 4 as shown in FIG. The guide mechanism 20a, 20b is opened (the reel 15 leaving the reeling position), and in the replacement position, the reeling shaft 14 with the new reel 15 is sent to the reeling position in the reeling preparation state, and the sheet S passes over the new reel 15.

Then, by operating the first winding cylinder 21a and the second winding cylinder 21b, the upper and lower guide mechanisms 20a, 20b are rotated, as shown in FIG. 4, to close the upper and lower guide mechanisms 20a, 20b The state (the state of the reel 15 close to the winding position).

At this time, as shown in FIG. 7(a), one pair of support rollers 27 of each guide mechanism 20a, 20b are located on the upstream and downstream sides with respect to the axis of the reel 15 and the pressure roller 29 is located above and below the reel 15. In addition, the pair of support rollers 27 and pressure rollers 29 of the upper guide mechanism 20a press (closely contact) the guide belt 30 and the sheet S on the upper surface side of the roll 15, and one of the lower guide mechanisms 20b The support roller 27 and the pressing roller 29 only press the guide belt 30 on the lower surface side of the spool 15. In addition, although not shown in the figure, the upper and lower guide rollers 22, the sheet clamp 23, and the cutting blade 24 approach the sheet S in the vicinity of the turntable rotating shaft 12.

From the state of FIG. 7(a) described above, the upper and lower sheet clamps 23 are operated to clamp the sheet S, and the cutting blade 24 is moved in the sheet width direction to cut the sheet S. Then, as shown in FIG. 7(b), the pulling roller 3 (refer to FIG. 1) is reversed, and the sheet S is pulled back until the cut end portion on the upstream side of the sheet S reaches the winding position. Then, by driving the second motor 17 (refer to FIG. 1) connected to the winding shaft 14 at the winding position, as shown in FIG. 7(c), the winding shaft 14 and the reel 15 are rotated integrally ( (Left rotation in the figure), the cut end of the upstream side of the sheet S is fed between the guide belt 30 of the lower guide mechanism 20b and the reel 15, and further fed into the guide of the upper guide mechanism 20a Between the leader tape 30 and the reel 15, the sheet S is wound around the reel 15.

After that, when the winding amount of the sheet S to the reel 15 reaches a certain amount, the upper and lower guide mechanisms 20a and 20b are opened to avoid interference with the sheet S wound on the reel 15. Then, at the time when the take-up shaft 14 at the take-up position rewinds a specific amount of sheet S, the turntable arm 13 of the turntable mechanism 5 is wound and rotated by 180°, thereby switching between the take-up position and the replacement position 2 The winding shaft 14 is set to the winding preparation state, the reel 15 wound with the sheet S is unloaded from the reeling shaft 14 fed to the replacement position, and a new reel 15 is installed on the winding shaft 14轴14.

By repeating the above-mentioned operations, even if the sheet S is of high rigidity, the cut end portion can be reliably and automatically brought into close contact with the reel 15 at the reeling position, and the reeling operation can be continuously performed.

In addition, although the illustration is omitted, when the sheet S supplied from the upstream side is wound from the lower surface side of the reel 15 (hereinafter referred to as "lower winding"), this procedure is also the same as the above-mentioned upper winding. The situation is roughly the same. That is, first, in the winding preparation state where the upper and lower guide mechanisms 20a, 20b of the winding unit 4 are opened, when the sheet S passes under the reel 15, it is set to set the upper and lower guide mechanisms 20a, 20a, In the closed state of 20b, the sheet S is cut by the cutting blade 24. Then, the traction roller 3 is reversed, the sheet S is pulled back until the cut end on the upstream side reaches the winding position, and the winding shaft 14 and the reel 15 in the winding position are rotated integrally (with the upper winding The winding situation is reversed), and the sheet S is wound on the reel 15.

After that, as long as the winding amount of the sheet S on the reel 15 reaches a certain amount, the upper and lower guide mechanisms 20a, 20b are opened, and the winding shaft 14 at the winding position winds the specified amount of the sheet S. , The turntable arm 13 of the turntable mechanism 5 is wound down and rotated 180ﾟ, the positions of the two winding shafts 14 are exchanged to set the winding preparation state, and the winding shaft 14 fed to the replacement position is replaced with the reel 15 Can.

Furthermore, in this sheet winding device, since the sheet winding operation is performed as described above, it is different from the case where the sheet S continuously supplied from the upstream side is divided and wound to a plurality of rolls 15 by Appropriately select the rotation direction of the turntable arm 13 (the operating direction of the turntable mechanism 5) when the two winding shafts 14 are exchanged between the winding position and the replacement position, and the same winding method can be continued between the reels 15 or switched Forward winding and reverse winding.

That is, in the case of upper winding, if the turret arm 13 is rotated (left rotation in FIG. 1) by the way that the reeled sheet S passes over the rotary shaft 12 of the turret, a new reel is installed The winding shaft 14 of the drum 15 is continuously fed from below to the winding position. Since the sheet S passes above the new drum 15, the same continuous winding method is adopted. On the other hand, if the turntable arm 13 is rotated in the opposite direction (right rotation in FIG. 1), the sheet S passes under the new reel 15, so that it is possible to switch between the forward winding and the reverse winding ( Change the winding method from forward winding to reverse winding, or change from reverse winding to forward winding). In addition, in the case of bottom winding, if the turret arm 13 is rotated in a way that the rolled sheet S passes over the turntable rotation shaft 12, the forward winding and the reverse winding can be switched. If the turntable arm 13 is rotated in the opposite direction, the same winding method can be continued.

Moreover, in the sheet winding device, when the used reel 15 is switched to a reel with a different outer diameter, the positions of the support rollers of the upper and lower guide mechanisms 20a, 20b are also adjusted in the winding preparation state The mechanism and the pressure roller position adjustment mechanism are activated to move the support roller 27 and the pressure roller 29 corresponding to the outer diameter of the new reel 15, and the tension adjustment mechanism is activated to adjust the tension of the guide belt 30 to an appropriate level. It is possible to start the winding operation of the new reel 15 without disassembling and assembling each component of the winding unit 4, etc.

For example, Fig. 8 shows the state at the start of winding when the reel 15 with a larger outer diameter is used based on the reel 15 shown in Fig. 4. In the state of FIG. 8 from the state of FIG. 4, by operating the screw operating piece 45 of the support roller position adjustment mechanism to rotate the screw shaft 41, the upstream and downstream support rollers 27 and the support 31 are integrated in Slide in the direction away from each other, and then operate the support roller cylinder 34 to finely adjust the position of each support roller 27, and operate the pressure roller cylinder 52 of the pressure roller position adjustment mechanism to move the pressure roller 29 away from the two support rollers 27 Move and operate the tension roller air cylinder 50 of the tension adjustment mechanism to rotate the tension roller 28 on the upstream side, thereby adjusting the tension of the guide belt 30.

The sheet winding device can be easily handled by operating the support roller position adjustment mechanism, the pressure roller position adjustment mechanism, and the tension adjustment mechanism when the outer diameter of the reel 15 is switched as described above. Compared with the previous sheet winding device, such as the disassembly and assembly operation of each component of the winding unit, the operation rate of the production line can be greatly improved, and the work load can be greatly reduced.

In addition, the sheet winding device of the present invention uses not only the resin sheet as in the embodiment, but also a strip-shaped sheet such as paper or laminated paper as a winding object.
