Next, the tape sticking device 1 having the above structure
The action of 0 will be described with reference to FIGS. 1 and 5 to 10. In the present embodiment, when the work piece is a cylindrical raw material which has been packaged and the adhesive tape is attached in a cross shape as shown in FIG. 11 on both end surfaces thereof, that is, the gathering portion of the wrapping paper. Will be described. In addition, as described above, the present apparatus is configured such that the two tape sticking apparatuses 10 are provided so as to face each other. However, since the operation of both apparatuses is exactly the same, one of the apparatuses is used. Only the action will be described.

First, as shown in FIG. 1, a raw material (workpiece)
1 is placed on the support base 85, and the end surface of which the gathering is completed is made to face the pressing surface 55a of the tape applying device 10. The support table 85 is usually attached to a line conveyor (not shown) that conveys the original fabric 1,
The original fabric 1 that has been packaged is automatically placed on the support table 85 by being conveyed on the line conveyor from the previous packaging process. Although there is a roll 1 having various diameters, the axial center of the roll 1 is attached to the tape sticking device 10 by the upper and lower bases 88.
The first and second rotating shafts 17 and 31 are adjusted to be on the same axis. In the fully-automatic process, the outer diameter of the original fabric 1 is measured in advance by an appropriate means, and the height of the support base 85 is automatically set based on the data.

First, the frame 13 is located at the outermost position of the movable base 12 as shown in FIG. The position adjustment of the frame 13 in order to correspond to the axial length of the original 1 is performed by sliding the moving base 12 on the support base 11. In addition, a pair of tape grippers 45
A and 45B are positioned in the vertical direction as shown. The tape roll holding roller 68 of the tape holding portion 62
A tape roll TR is set in (FIG. 1). The cut end of the adhesive tape T fed out from the tape roll TR is in a state when the tape attaching operation to the previous original fabric is completed, that is, the tape holding tool 4 located above.
It is in a state of being pinched by the first pinching portion 48 of 5B. In this state, the adhesive surface Ta of the adhesive tape T faces the side on which the original fabric 1 is set. Both the tension roller 69 and the guide roller 63 come into contact with the non-adhesive surface of the adhesive tape T. Also at this time,
The two tape grippers 45A and 45B are set such that their distance, that is, the distance between the inner end surfaces 45a and 45a is slightly larger than the diameter of the original fabric 1.

In order to attach the adhesive tape T to the end surface of the original fabric 1 from the above initial state, first, as shown in FIG.
The rotary frame 22 provided with the two tape grippers 45A and 45B is rotated by 180 ° around the first rotary shaft 17. This operation is performed by the rotary frame driving actuator 1
9 is driven, and the pinion 18 is rotated via the rack gear 20.

By the above operation, the one tape holding tool 45
The adhesive tape T having the cut end sandwiched by B receives a tensile force in its width direction as shown in FIG.
The pulling force when the adhesive tape T is fed is first applied to the guide roller 63. Since the guide roller 63 is provided on the support frame (small) 74 that is rotatable by the shaft 75, this guide roller 63 is provided. When the roller 63 receives a force in an oblique direction, the roller 63 swings and inclines obliquely as shown in the drawing. At the same time, the tape roll T
The R and the tension roller 69 are also tilted integrally with the guide roller 63, so that the adhesive tape T can be smoothly fed out.

The feeding of the adhesive tape T will be further described below. The convex band 79 is formed on the guide roller 63. This is because the adhesive tape T that has received the lateral pulling force as described above is the guide roller 6
The reason for this is to surely prevent the protrusion 3 from escaping in the width direction by the edge action of the convex band 79. In addition, the tape roll T held by the tape roll holding roller 68
R is fixed by the cap 73, but the tape roll TR is urged toward the cap 73 side by the tacks 71, 71, ... (FIG. 4) provided on the side opposite to the cap 73. .. Therefore, it is possible to apply a braking force to the rotation of the tape roll TR by adjusting the tightening force of the cap 73, whereby the tension at the time of feeding the adhesive tape T can be properly adjusted.

As described above, the rotating frame 22 rotates while the first holding portion 48 of the one tape holding tool 45B holds the cut end of the adhesive tape T, but the first holding portion 48 is rotated. Since the sandwiching pieces 50 and 51 that are configured are supported by the bearings 59 and 59 (FIG. 2), they can be pulled out as shown in FIG. 5 without applying an excessive force to the adhesive tape T.

FIG. 6 shows a state in which the rotary frame 22 is rotated by 180 ° while the adhesive tape T is sandwiched by the one tape clamping tool 45B as described above. In this state, the adhesive tape T is still on the first holding part 4 of the tape holding tool 45B.
It is pinched by only eight. The other tape holder 4
5A is pulled out from the tape roll TR and moves to a position corresponding to the adhesive tape T existing between the tape gripping tool 45B and the guide roller 63.
Fits in both the first and second tape holding parts 48, 49 of the tape holding tool 45A.

Next, the tape holding tool 4 which is at the bottom at the present time
The adhesive tape T sandwiched only by the first sandwiching portion 48 of 5B is further attached to the second sandwiching portion 49 (sandwiching pieces 52, 53) of the tape sandwiching tool 45B, and the tape sandwiching tool 45A located above. 1st clamping part 48, 2nd clamping part 4
It is also clamped by 9. That is, in this state, all the tape holding portions hold the adhesive tape T.

After that, the cutter 54 of the tape holding tool 45A located above is projected toward the adhesive tape T side to cut the adhesive tape T. After cutting the adhesive tape T, the first holding portion 48 and the second holding portion 49 of the lower tape holding tool 45B, and the upper tape holding tool 45A.
The holding operation of the second tape holding tool 49 is released. That is, the adhesive tape T is in a state in which its cut end is held only by the first holding portion 48 of the upper tape holding tool 45A. At this time, it is cut and both tape holding tools 45 are cut.
The adhesive tape Ta between A and 45B has an adhesive surface Ta of the holding piece 52 of the tape holding tool 45A and the tape holding tool 4
It is held between both tape holding tools 45A and 45B by adhering to the holding pieces 50 and 52 of 5B.

Thereafter, as shown in FIG. 7, the frame 13
When the whole is slid on the movable pedestal 12 to the side of the original fabric 1 (the movable pedestal 12 is not moved), the adhesive surface Ta of the adhesive tape T abuts on the end face of the original fabric 1 as illustrated.
When the frame 13 is further moved in the same direction from this state, as shown in FIG. 8, the two tape holding tools 45A and 45B holding both ends of the adhesive tape T are attached to the side surface 1b of the original fabric 1.
Side, that is, the peripheral body surface side. By this operation, both ends of the adhesive tape T sandwiched between the two tape sandwiching tools 45A and 45B are pulled forward by the tape sandwiching tools 45A and 45B (moving direction). The adhesive force of the adhesive tape T adhered to 52 is lost by the pulling force and separates from the sandwiching pieces 50 and 52.
After that, the adhesive tape T separated from the sandwiching pieces 50, 52
Both ends of the tape are guided by the inner end surfaces 45a of the moving tape holding tools 45A and 45B so as to be tilted toward the side surface 1b of the original fabric 1 and attached to the side surface 1b. Also, by moving the frame 13 toward the original fabric 1 in this way,
Eventually, the pressing surface 55a formed by the pressing member 55 provided between the two tape grippers 45A and 45B comes into contact with the end surface 1a (FIG. 2) of the original fabric 1, and the adhesive tape T is attached to the end surface 1a.
Press down on it enough. This completes the attachment of the adhesive tape T to the end surface 1a of the original fabric 1.

When the adhesive tape T is further attached (for example, in a cross shape) to the end surface 1a, the frame 13 is once retracted from the above state as shown in FIG. Thereafter, as shown in FIG. 10, the original fabric 1 is rotated by 90 ° in the circumferential direction on the support base 85. The rotation of the original fabric 1 can be performed by driving the support roller 86 by operating the motor 87. Then, along with the above operation, the rotary frame 22 is rotated by 180 ° as shown, this time in the direction opposite to the previous direction. Inversion of the rotating frame 22
The rotation frame driving actuator 19 is operated to drive the pinion 18 via the rack gear 20. Also in this case, since the cut end of the adhesive tape T is held only by the first holding portion 48 of the tape holding tool 45A, the turning operation can be performed while the adhesive tape T is held. Further, in this case, the guide roller 63 and the tape holding portion 62 are inclined in the tape pull-out direction as illustrated.

When the rotary frame 22 is inverted by 180 °, the tape holding tool 45A holding the adhesive tape T is positioned on the lower side, and the other tape holding tool 45B is positioned on the upper side, the tape holding tool 45B is provided. The adhesive tape T is cut by the cutter 54, and thereafter, the cut adhesive tape T is cut in the same manner as in the case described above with reference to FIGS. 6 to 8.
Is attached to the end surface 1a of the original fabric 1. by this,
Adhesive tapes T, T are attached to the end surface 1a of the original fabric 1 as shown in FIG. The same operation as described above is simultaneously performed on the other end surface (not shown) of the original fabric 1 by the other tape sticking device installed corresponding to the end surface.

When the outer diameter of the original 1 is different, the motor 38 (FIG. 2) may be driven. Pulley 39,
The second rotating shaft 31 rotates via the belt 40 and the pulley 36, and the ball screws 27 and 27 also rotate via the bevel gears 34 and 35. As a result, the moving block 46 that constitutes the base end portion of both the tape grippers 45A and 45B.
Moves along the guide rods 26, 26, respectively, and the distance between the two tape grippers 45A, 45B is adjusted.

As described above, according to the tape applying apparatus 10, even after the portion of the adhesive tape T to be attached to the original fabric 1 is cut off by the cutter 54, the adhesive tape T fed from the tape roll TR is cut. The first holding portion (holding piece 50,
It is held in the state of being pinched by 51) from beginning to end. Therefore, it is possible to reliably perform the feeding operation of the adhesive tape T to be attached next without any mistake.

Further, the both tape holding members 45A, 45
