The rotating device 10 comprises a driving roll 11 and a driven roll.
The drive roll 11 is connected to a motor 13 in a chain. When the drive roll 11 is rotated, the winding roll R can be rotated in the arrow a direction. The rotation angle of the take-up roll R, that is, the stop position, is controlled by the take-up roll diameter and the number of roll rotations of the rotating device 10. In addition, 14 is a kicker for feeding the take-up roll R, and 15 is a cylinder for its operation.

A pair of columns 1 are erected on both sides of the rotating device 10 as shown in FIGS. 1 and 2, and saddles 2 are attached to the guide rails inside each column 1, respectively.
Further, each saddle 2 is screwed onto a screw shaft 3 arranged on the column 1. Each screw shaft 3 is connected to the motor 5 via the synchronous shaft 4. A side beam 19 for running the tape applying device 20 and a side beam 29 for supporting the cutter device 30 are connected to the saddle 2. Therefore, when the motor 5 is rotated, the tape applying device 20 and the cutter device 30 are moved up and down. The ascending / descending position is controlled based on winder data regarding the diameter of the winding roll R or data measured by a measuring device attached to the present apparatus.

The tape applying device 20 will be described with reference to FIGS. A traveling plate 21 is supported on a rail attached to a side surface of the side beam 19, and the side beam is further supported.
A motor 22 is attached to one end of 19 and a sprocket 23 is attached to the other end. The traveling plate 21 is connected by a chain 24 wound around a motor 22 and a sprocket 23.
When 22 is rotated, the traveling plate 21 travels on the side beam 19. A tape sticking magazine 26 is attached to the traveling plate 21 via a parallel link 25.
By expanding and contracting the cylinder 27 connected to one end of 25, the tape sticking magazine 26 can be lowered or pulled up. Then, when the tape sticking magazine 26 is lowered and pressed against the sticking surface to run, the double-sided tape T is stuck to the sticking surface only during that time. Only the double-sided tape T that has been torn off and affixed remains on the affixed surface. It should be noted that the length of sticking the double-sided tape T may be input in advance to the controller of the tape sticking device 20 with a digital switch or the like, or may be set based on the slit width data of the winding roll R as appropriate. Good.

In FIG. 1, reference numeral 30 denotes a cutter device for cutting the moisture-proof sheet S, which includes a cutter 31, a length measuring sensor.
32, an operating cylinder 33. 29 is a side beam and is fixed between the left and right saddles 2. More specifically, referring to FIG. 4, reference numeral 35 denotes a guide rail attached to the side beam 29, which supports the moving base 36 so that it can travel. This moving platform
The working cylinder 33 is fixed to the working cylinder 33, and the working cylinder 33 is connected to an arm 38 having a cutter 31 attached to the tip thereof. In addition, the cutter 31 is a blade on the disk on the roll 39.
37 is fixed. 41 is the side beam 29
The movable base 43 of the positioning cylinder 42 is movably attached by a guide rail fixed to the guide rail 41, and the attachment position on the guide rail 41 can be arbitrarily set. The length measuring sensor 32 is for exploring the slit position, and a laser displacement sensor or an ultrasonic sensor capable of measuring the distance in a non-contact manner is used.

The necessary number of the above-mentioned cutter devices 30 are mounted on the side beams 29 according to the number of slits in the roll. Initially, the setting at the slit position is performed manually by looking at the scale plate on the machine side, but since accurate positioning is performed as follows, the initial manual setting may be rough positioning. That is, as shown in FIG. 5, while the distance measuring sensor 32 measures the distance to the winding roll R, the positioning cylinder 42 slowly moves the moving table 36 to find the slit portion c of the winding roll R. .. Measurement data da at slit location c
Since it protrudes in a mountain shape, when returning once over the slit portion c and returning again, the cutter 31 can be accurately positioned at the slit position c by stopping at the mountain position of the length measurement data da. .

As shown in FIG. 1, a sheet feeding device 50 is provided on the exit side of the winding roll R, that is, on the right side of the drawing. Reference numerals 6 are left and right columns, and saddles 7 are attached to the inside of each column 6 so as to be able to move up and down, and the end portion of the piston rod is connected to the saddle 7 so that it can be moved up and down by the operation of a cylinder 8. .. The solid line shows the working position of the sheet feeding device 50, and the imaginary line shows the rising position.
The ascending / descending position is also controlled based on winder data indicating the diameter of the take-up roll R and data measured by a measuring device attached to the present apparatus.

As shown in detail in FIG. 6, a side beam 49 is fixed between the left and right saddles 7, and the sheet roll SR of the moisture-proof sheet S is placed on the roll base 51 on the side beam 49. It is placed. Since the entire width of the take-up roll R is generally wider than the width of the moisture-proof sheet S, two sheet rolls SR are used in this embodiment. However, depending on the total width of the take-up roll R, one roll is sufficient. In some cases, three or more may be used. A pinch roll 52 is driven by a motor (not shown). 53 is a pressing roll, which can be moved by a cylinder 54.
The moisture-proof sheet S is sandwiched between and, and the moisture-proof sheet S is sent out. 55 is a knife for cutting the moisture-proof sheet S in the width direction, which is moved forward and backward by a cylinder 56.
Cut the moisture barrier sheet when moving forward.

Reference numeral 57 denotes a guide plate, which has a small hole formed on the surface in contact with the moisture-proof sheet S, and has a hollow chamber structure which is hollow and is connected to a vacuum pump or the like. The guide plate 57 guides the moisture-proof sheet S in the direction of the take-up roll R, and sucks the moisture-proof sheet S as necessary to apply tension. Reference numeral 58 is a guide roller for the moisture-proof sheet S, and 59 is an air nozzle for blowing the moisture-proof sheet S downward. Reference numeral 61 is a protruding frame, which is moved forward and backward by a cylinder 62. A pressing roll 63 is attached to the front end of the pressing roll 63. Both the frame 61 and the roll 63 have a vacuum structure and can suck and hold the moisture-proof sheet S.

Next, the moisture-proof sheet S by the above-mentioned winding device
The wrapping work will be described with reference to FIGS. First, the winding roll R finished by the winder part WP is moved to the rotating device 10. However, a positional deviation d in the width direction may occur while moving the floor 16 as shown in FIG. In this case, the position of the cutter device 30 is manually adjusted to the slit position c of the winding roll R. It should be noted that this alignment can be performed roughly because it can be accurately positioned later as described above. Then, the screw shaft 3 is rotated by the motor 5 to lower the saddle 2. As a result, the tape applying device 20 and the cutter device 30 are located at the work position which is the closest position to the winding roll R. At the same time, the cylinder 8 is contracted so that the sheet feeding device 50 is located at the work position right next to the winding roll R.

Then, the tape sticking device 20 sticks the double-sided tape T on the take-up roll R in the width direction. In this case, as shown in FIGS. 9 (A) and 9 (B), if the tape is attached so as not to cover the slit position c of the take-up roll R, the cutter 31 will be double-sided when cutting the moisture-proof sheet in the next step. Since the adhesive of the tape T is not cut, the sharpness is not deteriorated, which is preferable.

Next, as shown in FIG. 10, the rotating device 10 is driven to rotate the winding roll R by about 90 degrees. This allows
The double-sided tape T moves from the attachment position shown by the dotted line to the position near the sheet supply position shown by the solid line. At the same time, as shown in FIG. 6, the moisture-proof sheet S is fed out by the pinch roll 52 and the pressing roll 53, and guided to the tip of the pressing roll 63 via the guide plate 57. Then, the cylinder 62 is extended, and the pressing roller 63 is pressed against the winding roll R as shown in FIG.
The moisture-proof sheet S is sandwiched between the winding roll R and the winding roll R. Then, the cylinder 54 shown in FIG. 6 is contracted to separate the pressing roll 53 from the pinch roll 52 to make the supply of the moisture-proof sheet S free, and the rotating device 10 is driven to wind the winding roll R as shown in FIG. Is further rotated in the direction of arrow a. At this time, the moisture-proof sheet S is pulled out from the sheet roll SR as the winding roll R rotates. Since the moisture-proof sheet S is tensioned during this time, the guide plate 57 and the projecting frame 61 are vacuumed to add resistance in the back direction to the moisture-proof sheet S. As a result, slack does not occur in winding the moisture-proof sheet S.

Then, when the front end of the moisture-proof sheet S temporarily wound around the winding roll R slightly passes under the tape applying device 10, the rotating device 10 is stopped and the moisture-proof sheet S is closed.
The double-sided tape T is attached to the outer surface of the front end portion of (the attachment position is indicated by a dotted line). This work is performed in the same manner as the first tape application work. The moisture-proof sheet S is cut while the take-up roll R is rotating, when the feeding length of the moisture-proof sheet S reaches a predetermined length. Then, the cylinder 56 of FIG. 6 is extended and the rear end of the moisture-proof sheet S is cut by the knife 55. As a result, the moisture-proof sheet S is cut into one roll length.

Next, as shown in FIG. 12, when the rotating device 10 is driven again and the winding roll R is rotated, the moisture-proof sheet S is further pulled out, and resistance is exerted on the guide plate 57 and the attachment frame 61. It is wound on the take-up roll R while being hung. Finally, the double-sided tape T and the rear end of the moisture-proof sheet S are pressed against the pressing roll 63 and bonded. This completes the winding of the moisture-proof sheet S. As shown in FIG. 12, when the rotating device 10 is stopped after the bonding point has passed the nip point B, the double-sided tape is bonded more securely by the weight of the take-up roll R.

When the winding of the moisture-proof sheet S is completed as described above, the motor 5 is driven to raise the tape applying device 20 and the cutter device 30, and the cylinder 8 is extended to raise the sheet feeding device 50. Then, the take-up roll R wound with the moisture-proof sheet S is sent out from the rotating device 10 by the kicker 14.

According to this embodiment, since the moisture-proof sheet can be automatically wound as described above, the labor-saving effect is great, and the winder device can be operated separately from the winder device, thus improving the winding ability of the winder device. be able to.
