Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet winding preparation device, in which a sheet dividing winder that replaces a wound sheet roll with a new winding shaft in a turret manner cuts the sheet at the rear of the wound sheet roll; The purpose is to high-quality mechanize the preparatory work for resuming winding by attaching the cut end to the winding core which is inserted onto a new winding shaft.

Previously, the above preparatory work had been mechanized, but this was limited to roughly cutting the sheet and then using compressed air to spray glue the cut ends onto the winding core, which was inserted onto the winding shaft. It was of low quality, with sagging, wrinkles, etc. Therefore, when high quality is required, the cut end is manually glued to the core.

However, when it is performed manually, skill is required for accurate adhesion work. In particular, in the case of a sheet dividing winder that divides a wide sheet using a slitter and winds it into multiple strips, many sheets must be accurately glued to each new core without misalignment or distortion, which is a hassle. , and difficult.

In the sheet dividing winder, this invention has the following features:
To provide a simple device capable of bonding high-quality cut ends without using human hands. The key point is that double-sided adhesive tape is applied in advance to the entire width of the wide sheet before it enters the slitter, rather than applying adhesive to each core or the cut portion of each sheet as in the past. If the sheet itself has an adhesive side, attach a sheet of paper. Therefore, the double-sided adhesive tape-applied portion and the pick-up paper-applied portion are then divided by a slitter and directed toward the winding shaft. Then, a counting or detection device is installed to stop the sheet running the moment it reaches or crosses the winding shaft, and the part of the stopped sheet with double-sided adhesive tape is pressed along the outer circumferential surface of the winding core that has been extrapolated onto a new winding shaft. It has a pressure device equipped with a pressure member with a pressure surface, and a cutting device that advances along the pressure member and cuts the sheet, so even if the sheet is divided into multiple strips, all the sheets will be cut accurately and without distortion. Since the sheet is attached to the winding shaft or winding core and is cut along the pressing member that is in a pressed state, there is no need to worry about winding up excess sheets or the cut end coming off the winding core due to sheet tension. The paper will be attached to the rear of the sheet roll.

Next, the configuration and embodiments of the present invention will be specifically described with reference to the drawings. Figure 1 is the first example of this invention.
This is an explanatory diagram showing an embodiment, in which double-sided adhesive tape is applied to the sheet S across the sheet travel path before entering the slitter 1, or if the sheet S has an adhesive surface, a sheet of paper is attached to the adhesive surface. The device 2 for applying and sticking the double-sided adhesive tape in a straight line in the width direction and the moment when the double-sided adhesive tape-applied portion A of the sheet S reaches the new roll shaft 3, or the moment when the cut-off paper-applied portion B crosses over the roll shaft 3. A counting device 4 (or a detecting device) that stops the sheet traveling at the same time, and a counting device 4 (or a detection device) that advances from the standby position and extrapolates the adhesive surface of the sheet S immediately after the double-sided adhesive tape applied portion A or the slip-applied portion B onto a new winding shaft 3. A pressurizing device 5 that presses against the winding core, and a pressurizing device 5 that is in the pressed state
A cutting device 6 advances along the pressure member 5a of the sheet roll R to cut the trailing sheet of the sheet roll R, and each roller (not shown) that comes into contact with the adhesive surface of the double-sided adhesive tape applying portion A or the sheet itself It is made sticky.

In the figure, a device 2 for applying double-sided adhesive tape or pick-up paper in a straight line across the sheet S in the width direction of the sheet is shown in the figure. Or it can be pulled by a chain.

A backing 2a is placed on the back side of the sheet S.
has been established. The front side corresponds to the winding shaft 3, and is the surface to which the double-sided adhesive tape is applied or the adhesive surface of the sheet itself.

Sheet S from the position where the double-sided adhesive tape and paper is applied to the position where the new winding shaft 3 enters the winding position
The distance traveled remains unchanged. Therefore, when the sheet S is stopped, a double-sided adhesive tape and a slip are applied, and the running is resumed and the distance traveled reaches a certain value, the counting device 4
When the signal is transmitted and the sheet travel is stopped, the double-sided adhesive tape applied part A will stop at A' where it is placed on the winding shaft 3, or the cut-off paper applied part B will stop at B' where it is over the winding shaft 3. can do. The counting device 4 may count not the running of the sheet S but the rotation angle of the feeding roller.

In addition, double-sided adhesive tape (cut paper) is detected by the detection device.
It may be possible to detect when the applied portions A and B reach the winding shaft 3; in that case, it is left to the on-site engineer's creative efforts, such as attaching a reflective tape nearby that is easy to detect, or attaching a detection target to the sheet edge. .

The pressurizing device 5 presses the pressurizing member 5a toward the winding shaft 3 using, for example, the fluid pressure cylinder 7 shown in FIG. During winding, the arm is rotated and retracted by a drive mechanism (not shown). The pressure member 5a has a pressure surface that is shaped to fit the outer periphery of the winding shaft 3 or the winding core, and rubber or the like is pasted on the pressure surface. Therefore, the sheet S can be evenly and reliably pressed against the winding core inserted onto the winding shaft 3.

The cutting device 6 itself is well-known and is therefore depicted in a simplified manner; however, it is retracted when not in use, and comes out only when the pressing device 5 presses the sheet S against the core inserted onto the winding shaft 3. The sheet S is cut while being guided by the pressure member 5a in this state. In this example, the running mechanism uses a chain to pull and run the blade.

Incidentally, reference numeral 8 in FIG. 1 is a well-known turret plate for rotating and replacing the winding shaft 3 and the sheet roll R as necessary.

The double-sided adhesive tape applying portion A, including the slitter 1, and the rollers in contact with the adhesive surface of the sheet itself are made of silicone rubber to prevent adhesion, or the surfaces are made rough to prevent adhesion.

FIG. 2 shows an embodiment in which the present invention is applied to a vertically distributing type dividing winder. The illustration of the counting (or detection) device is omitted. The guide rollers 9, 9 that vertically distribute the sheets S divided by the slitter 1 are connected to the pressure device 5.
It is coaxial with the rotating arm 10 for advancing and retracting. The arm 10 is further provided with an upper guide roller 11 and upper and lower touch rollers 12 that contact the surface of the sheet roll to prevent air from being entrained. The illustration of the hydraulic cylinder for swinging the arm 10 is omitted. Since the device shown in FIG. 2 is functionally the same as that shown in FIG. 1, detailed explanation will be omitted.

FIGS. 3 and 4 show two examples of how to cut the sheet S with the double-sided adhesive tape applied portion A' fixed on the core of the winding shaft 3. Figure 3 shows the area where double-sided adhesive tape is applied.
The sheet S is cut along the edge of A', but the fourth
The figure shows an example in which the double-sided adhesive tape application area A' is divided into front and back parts, and the front part is used as the adhesive part for sealing the trailing sheet end of the sheet roll.

Note that, as shown as B' in FIGS. 1 and 2, the pick-up paper application portion B serves as a knob for rewinding the sheet roll R at the rear end of the adhesive surface of the trailing sheet of the sheet roll.

The embodiments of the present invention have been described above for both the case where the sheet is a normal (non-adhesive) sheet and the case where the sheet has an adhesive surface. In either case, a designer can make various changes and applications according to implementation conditions using well-known techniques without changing the gist of the invention.

This invention can provide the simplest and highest quality winding preparation device for a split winder where winding preparation is extremely troublesome.

That is, before entering the slitter, double-sided adhesive tape or slicing paper is applied to the entire width of the sheet, and then it is divided by the slitter, so that each divided sheet is completely wrapped with adhesive and slitting paper and placed on the roll shaft. reach or,
A device that applies double-sided adhesive tape or slip paper to the sheet on the sheet travel path before reaching the slitter, and a device that applies double-sided adhesive tape or paper to the sheet on the sheet travel path before reaching the slitter. Since it is equipped with a pressurizing device that presses along the sheet and a cutting device that cuts all at once after pressurizing, the adhesion and cutting operations can be performed regardless of changes in the sheet division specifications by the slitter. Furthermore, since the surfaces of the guide rollers and the like are made non-adhesive, the double-sided adhesive tape will not peel off and the roller side will not get dirty.

In particular, in the case of regular sheets, the divided sheets travel straight along the running path and the double-sided adhesive tape-applied portions are adhered to the respective cores all at once, so there is no shift or distortion in the adhesion positions that would occur if done manually. It is equipped with a pressure member having a predetermined pressure surface that presses the part to which the double-sided adhesive tape is applied along the outer circumferential surface of the winding core which has been inserted onto a new winding shaft, and is pressed immediately next to the adhesion (pressure) position. Since the sheet is cut along the pressure member located in the sheet, the sheet can be cut accurately, and there is no risk of winding up excess play and interfering with precision winding. Moreover, since it is equipped with a device that applies the double-sided adhesive tape linearly in the width direction of the sheet, and a counting or detection device that accurately stops the application position of the double-sided adhesive tape on the winding shaft, a small amount of double-sided adhesive tape is sufficient. Since the area required for adhesion of the sheet can be reduced accordingly, the portion that cannot be used as a product can be kept to a minimum.

In addition, if the sheet itself has an adhesive surface, simply press the sheet to the new roll shaft and cut it, and the cut edge paper will be attached to the cut end of the sheet roll, making it extremely efficient.Moreover, as mentioned above, the sheet can be divided with the slitter. The resulting cutout paper corresponds to the width of the sheet roll.
