As shown in FIGS. 2 and 3, the sheet piece supply device 10 according to the present embodiment includes a sheet supply unit 11, a table 15, a guide bar (guide unit) 25, a paper pattern winding unit 31, and a sheet. A cutting portion 41 is provided.

The sheet supply unit 11 supports a sheet roll SR in which a long sheet LS is wound in a roll shape. The sheet roll SR is formed by winding a long sheet LS with the side having the adhesive tape T on which the release paper R is attached to the adhesive surface as the inside. A plurality of sheet supply units 11 are provided, and these sheet supply units 11 are arranged in parallel. The sheet piece supply device 10 has one roll support rod 13 extending in the width direction, and the roll support rod 13 is inserted in the center of the sheet roll SR in each sheet supply unit 11. As a result, the sheet roll SR of each sheet supply unit 11 is rotatably supported by the roll support rod 13. Then, in each sheet supply unit 11, the long sheet LS is pulled out from the lower part of the sheet roll SR in a substantially horizontal direction toward the table 15 side with the adhesive surface side on which the adhesive tape T is provided facing upward.

The table 15 is arranged on the front side in the drawing direction of the long sheet LS from the sheet supply unit 11. Each sheet supply unit 11 is arranged in the width direction of the table 15. The table 15 is tilted with the front end 15b on the opposite side of the rear end 15a on the seat supply portion 11 side lowered. A receiving plate 16 is provided on the front end 15b of the table 15 over the width direction. The receiving plate 16 projects upward from the upper surface of the table 15. The long sheet LS pulled out from the sheet supply unit 11 is fed onto the table 15 from the rear end 15a side. Then, the long sheet LS is cut on the table 15 by the sheet cutting portion 41 to obtain a sheet piece S. The sheet piece S slides on the table 15 along the inclination to the front end 15b of the table 15, and is received by the receiving plate 16.

The table 15 includes the same number of detection units 21 as the sheet supply unit 11. The detection unit 21 has an optical sensor 22, and the optical sensor 22 is inserted into a window unit 23 formed on the table 15 from the lower side of the table 15. The optical sensor 22 optically detects the presence or absence of the long sheet LS on the table 15. The window portion 23 is formed of an elongated hole along the front-rear direction of the table 15 which is the drawing direction of the long sheet LS, and the detection portion 21 is formed in the window portion 23 formed of the elongated hole in the front-rear direction of the table 15. It is said to be movable. The window 23 of each detection unit 21 is formed at a position shifted in the front-rear direction of the table 15. As a result, the optical sensors 22 of each detection unit 21 can move in the front-rear direction of the table 15 at positions shifted in the front-rear direction on the table 15.

The guide bar 25 is formed of a rod body formed in a cylindrical or columnar shape, and is arranged in the vicinity of the rear end 15a of the table 15. The guide bar 25 is arranged along the width direction of the table 15 and is supported with a gap with respect to the table 15. The release paper R of the adhesive tape T of the long sheet LS drawn out from the sheet supply unit 11 is hung on the guide bar 25. That is, the release paper R of the adhesive tape T of the long sheet LS is peeled off from the adhesive tape T, hung on the guide bar 25, and guided in the upper peeling direction away from the long sheet LS.

The paper pattern winding unit 31 has a winding reel 32 rotatably supported around the horizontal axis. On the take-up reel 32 of the release paper take-up unit 31, the release paper R that is hung on the guide bar 25 and guided upward in the peeling direction is wound. The same number of release paper winding units 31 as the sheet supply unit 11 are provided and arranged in parallel. Each release paper winding unit 31 has a drive unit 35 composed of an electric motor. The drive unit 35 has a rotating shaft 35a, and the rotating shaft 35a is connected to the take-up reel 32. As a result, in each release paper winding unit 31, each take-up reel 32 is individually rotated by the drive unit 35, and the release paper R is wound on each take-up reel 32. Each release paper winding unit 31 is arranged at a position deviated in a direction orthogonal to the axial direction. As a result, the respective release paper winding units 31 are arranged so that the drive units 35 do not interfere with each other. The winding operation of the release paper R by the take-up reel 32 rotated by the drive unit 35 is stopped when the detection unit 21 of the table 15 detects the long sheet LS.

The sheet cutting portion 41 is provided above the rear end 11a of the table 15. The sheet cutting portion 41 has a rail 42 provided along the width direction of the table 15 and a cutter 43 movably supported by the rail 42. The sheet cutting portion 41 cuts the long sheet LS on the table 15 in the width direction by moving the cutter 43 along the rail 42.

Next, the operation of the sheet piece supply device 10 will be described.
FIG. 4 is a schematic front view of the sheet piece supply device for explaining the operation of the sheet piece supply device.

When the operator presses the start switch (not shown), the drive unit 35 of the paper pattern winding unit 31 is driven, the take-up reel 32 is rotated, and the paper pattern R is taken up by the take-up reel 32.

Then, the paper pattern R is pulled up, folded back by the guide bar 25, and peeled off from the long sheet LS. Further, the long sheet LS is pulled out from the sheet supply unit 11 by the tensile force acting on the paper pattern R, and is sent out from the rear end 15a of the table 15 onto the table 15.

As shown in FIG. 4, when the long sheet LS reaches the optical sensor 22 of the detection unit 21, the long sheet LS is detected by the optical sensor 22. Then, the driving of the driving unit 35 of the paper pattern winding unit 31 is stopped, the winding of the paper pattern R is stopped, and the feeding of the long sheet LS is stopped.

After that, the cutter 43 of the sheet cutting portion 41 moves along the rail 42, and the long sheet LS on the table 15 is cut in the width direction to form a sheet piece S. At this time, since the optical sensors 22 are arranged at positions shifted in the front-rear direction of the table 15 in each of the detection units 21, the long sheet LS sent out from the respective sheet supply units 11 is sent to the table 15. The delivery dimensions are different. Therefore, sheet pieces S having different length dimensions can be obtained from each long sheet LS.

Then, the sheet piece S slides down on the table 15 to the front end 15b due to its own weight, and is received by the receiving plate 16 (see FIG. 3).

The operator takes out the sheet piece S on the table 15 and winds the adhesive tape T side inward at a predetermined position of the wire harness. As a result, the sheet piece S is attached to the wire harness by the adhesive tape T sticking to the outer circumference of the wire harness or the outer circumference of the sheet piece S.

As described above, according to the sheet piece supply device 10 according to the present embodiment, the release paper R is wound around the take-up reel 32 of the release paper winding unit 31 to wind the adhesive tape T of the long sheet LS. The paper pattern R can be peeled off from the sheet, and the long sheet LS can be fed out from the sheet supply unit 11. Therefore, it is possible to eliminate the need for a mechanism for sandwiching the long sheet LS between a pair of rolls and feeding it out, and it is possible to reduce the size of the device and the equipment cost by simplifying the structure.

Further, since a plurality of sheet supply units 11 and release paper winding units 31 are arranged in parallel, and each release paper winding unit 31 includes a drive unit 35 for rotating the take-up reel 32, each of the long sheets The LS can be delivered independently. As a result, each long sheet LS can be individually and highly accurately fed as compared with the case where a plurality of long sheets are fed by one drive unit.

Moreover, since the release paper winding unit 31 is arranged at a position shifted in the direction orthogonal to the axial direction and the drive units 35 are arranged without interfering with each other, the width dimension of the device is suppressed as much as possible, and further device. Can be miniaturized.

Further, a detection unit 21 for detecting each long sheet LS is provided on the front side in the feeding direction of the long sheet LS, and the paper pattern winding unit 31 detects the long sheet LS by the detection unit 21. Since the winding operation for winding the release paper R on the take-up reel 32 is stopped, the length of the long sheet LS drawn out by the release paper take-up unit 31 winding the release paper R on the take-up reel 32 is increased. Can be set to precision. As a result, the long sheet LS can be accurately cut to a predetermined length and supplied as the sheet piece S. Further, since the optical sensor 22 of the detection unit 21 can be moved within the range of the window unit 23, the optical sensor 22 is moved within the range of the window unit 23 to adjust the detection position of the long sheet LS, and the sheet piece. The length of S can be easily adjusted.
