BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a pressure-sensitive adhesive tape cutting apparatus according to an embodiment of the present invention. FIG. 1 shows a state (standby position) of the adhesive tape cutting device when not in use (standby position), in which a casing 1 has a stand that can stand on its own, and forms a substantially arc-shaped side wall surface. , And a roll-shaped adhesive tape R can be detachably accommodated therebetween.

That is, on one inner wall surface of the box-shaped component 2, a cylindrical tape holding portion 3 for supporting the roll-shaped adhesive tape R in a detachable and rotatable manner is projected. In addition, a guide edge 4 that is gradually inclined upward is formed adjacent to the bottom surface of the box-shaped component 2. At the boundary between the bottom surface of the box-shaped component 2 and the guide edge 4, the temporary bonding portion 5 and the feeding guide portion 6 form a slight gap therebetween so as to be substantially along the guide edge 4. It is juxtaposed. This gap serves as a feeding port 7 for the tape T drawn from the roll-shaped adhesive tape R. In the present invention, for the sake of explanation, the tape portion pulled out from the roll-shaped adhesive tape R to the feeding guide portion 6 is referred to as an internal feeding tape portion T1, and the tape portion fed out of the feeding guide portion 6 is referred to as an external feeding tape portion T2. And

The temporary bonding portion 5 is located on the adhesive layer side (back side) of the internal feeding tape portion T1, and the feeding guide portion 6 is provided.
Is located on the front side of the tape portion T2. Upper end of guide edge 4 of box-shaped component piece 2 (end away from bottom surface)
In the vicinity, a pivot 8 having both ends fixed by a pair of box-shaped component pieces 2 is provided, and a movable body 9 is pivotally attached to the pivot 8 via a substantially middle portion thereof. The movable body 9 is formed in a box shape with an open top, has a bottom surface formed on a flat surface that is wider than the width of the adhesive tape to be mounted and extends forward and backward, and the flat surface serves as a pressing surface 10. I have.

The pressing surface 10 may be formed at least behind the pivot 8 of the movable body 9, but in this embodiment, the entire bottom surface is the pressing surface 10. On the bottom surface of the movable body 9, a front end portion 10 a, which is a front side in the tape pulling-out direction around the pivot 8, extends outward from the pair of box-shaped components 2, and is opposite to the rear side in the tape pulling-out direction. The rear end portion 10 b (original pressing surface) which extends to the side extends to the vicinity of the feeding guide portion 6. The movable body 9 is in a state where the pressing surface 10 is parallel to the guide edge 4 (pressing position).
2, the pressing surface 10 is provided so as to slightly protrude outside the guide edge 4 as shown in FIG.

Next, an arm 11 is fixed to a part of the movable body 9 above the rear end 10b. In the case of this embodiment, as shown in FIG. 3, when the movable body 9 is rotated by a predetermined angle, the end of the arm 11 presses the middle part of the internal feeding tape portion T1 against the temporary bonding portion 5, as shown in FIG. It can be adhered. A blade portion 12 is fixed to the movable body 9 in the vicinity of the rear end 10b of the pressing surface 10 of the movable body 9 so that the edge does not protrude below the pressing surface 10. In the present embodiment, the blade portion 1 is located at an intermediate position of the rear end face of the movable body 9.
2 is fixed at the base end and the cutting edge portion is a rear end 10b of a flat surface.
The tape is arranged slightly behind to allow a tape to be cut. Further, as shown in FIG. 1, a spring body is always used to keep the rear end 10b of the pressing surface 10 housed in the pair of box-shaped components 2 as shown in FIG. 13 is locked across the shaft 8 and the shaft 14. The shaft 14 also has a function as a stopper for keeping the rotation of the movable body 9 within a certain range.

Next, a method of using the tape feeding device having the above configuration will be described. First, a pair of box-shaped component pieces 2 is held in a hand, and the linear guide edge 4 is pressed against the tape application surface S. At this time, as shown in FIG. 2, the movable body 9 rotates against the elasticity of the spring body 13 so that the rear end 10b of the pressing surface 10 is directed outward, and the pressing surface 10 is covered with the tape. At the same time that the pressing surface 10 comes into contact with the bonding surface S and the free end of the external feeding tape portion T2 previously drawn out from between the temporary bonding portion 5 and the feeding guide portion 6, the pressing surface 10 is positioned on the tape bonding surface S. Press and adhere.

In this state, when the casing 1 is advanced in the direction a in the drawing, the tape T is pulled in the pull-out direction, and the portion adhered to the temporary adhesive portion 5 is peeled off, and the roll-shaped adhesive tape T is released. It becomes rotatable. Further, by moving the casing 1 in parallel in the direction a, the external feeding tape portion T2 sequentially fed by the rotation of the roll-shaped adhesive tape T is pressed by the pressing surface 10 and is advanced and adhered to the surface to be adhered to a desired length. Can be done.

When the sticking of a predetermined length is completed, the box-shaped component piece 2 is moved in the figure b while the pressing surface 10 of the movable body 9 is kept pressed against the sticking surface S as shown in FIG. The arm portion 11 makes contact with the temporary bonding portion 5 while bending the internal feeding tape portion T1 with the arm portion 11. As a result, the drawn-out tape T is fixed by bonding the external feeding tape portion T2 by the pressing surface 10, and the internal feeding tape portion T1 is bonded and fixed to the temporary bonding portion 5 to be tensioned. Then, by further slightly rotating the box-shaped component 2 in the direction b, the cutting is performed by pressing the blade portion 12 against the tensioned external feeding tape portion T2.

When the casing 1 is separated from the surface S to be adhered after the series of tape attaching and cutting operations, the movable body 9 is returned to the standby position shown in FIG. In the tape T, since the inner feeding tape portion is adhered to the temporary adhesive portion 5, the tip of the outer feeding tape portion T2 is kept returned from the feeding guide portion 4 without returning to the inside of the box-shaped component piece 2. It is. Therefore, in the next tape attaching operation, the rear end portion 10b of the pressing surface 10 of the movable body 9 can naturally catch the leading end of the external feeding tape portion and press and adhere to the tape attaching surface.

In the above embodiment, a cellophane tape is shown as an adhesive tape. However, various types of adhesive tapes such as a double-sided tape, a gum tape, and a cloth tape can be used as long as the adhesive tape is wound in a roll. In addition,
In the above-mentioned embodiment, an example in which a flat bottom surface is provided on a pair of box-shaped components has been described. However, such a bottom surface may not be provided, and the device may be able to stand alone by other means. FIG. 4 shows a different embodiment in which the temporary bonding portion 15 is provided above the box-shaped component 2 '. According to this, the arm 11 deforms a part of the tape T <b> 1 pulled out, and the deformed tape adheres to the temporary adhesive part 15, so that the tape T <b> 1 can be tensioned. Other configurations are the same as those in the above embodiment.

FIG. 5 shows a different embodiment of the movable body. The movable body 19 has a bracket piece 19a, and a pressing surface 10 is formed on a plate 19b pivotally attached to the shaft 8. At the rear end of the movable body 19, the movable body 19 abuts with a feeding guide portion (guide roller in the illustrated example) 6 at the time of pivoting. Rising piece 1 that rises in an arc so that it does not
9c and a tape fixing portion 11 'extending rearward at the upper end thereof and abutting against the temporary bonding portion 5'. In this case, the same operation and effect as the above embodiment can be obtained.

FIG. 6 shows a further different movable body 29. The movable body 29 has an arm 2 projecting rearward from a bracket piece 29a supporting a plate 29b having a pressing surface 10.
9c, and a tape fixing portion 11 "which abuts with the temporary bonding portion 5" is formed at the end thereof. Further, a coil spring C is used as the urging means of the movable body 29. In this case, the same operation and effect as the above embodiment can be obtained. Furthermore,
In the present invention, the direction for pressing the tape of the movable body may be the same as that of the above-described embodiment, and used in reverse. Further, in the present invention, the pressing surface may form a curved surface behind the movable body, or may have a roller pivotally attached thereto.

FIGS. 7 and 8 show different embodiments of the adhesive tape cutting device of the present invention disposed on a transport device. This device is provided with a roll-shaped adhesive tape R on a casing 21 held up and down by a lifting device (not shown).
Is held by the tape holding portion 23, and the movable body 29 is provided below the tape holding portion 23 so as to be able to move away from or approach the casing 21. That is, the movable body 29 can move up and down in parallel with respect to the casing 21 to expand and contract the gap between the movable body 29 and the roll-shaped adhesive tape R. Here, as a configuration for moving the movable body 29 up and down with respect to the casing 21, for example, a screw shaft G is provided vertically on the casing 21 so that the movable body 29 can be turned around an axis by a motor. An appropriate configuration such as a configuration in which the movable body 29 is moved up and down by rotating the shaft by mounting the nut-shaped receiving member 50 to be moved, or a configuration in which the movable body 29 is moved up and down by connecting the movable body 29 to a rod of an air cylinder attached to a casing. Can be used. Further, in the present embodiment, the protrusion 26 formed integrally with the movable body 29 serves as both the feeding guide portion and the arm portion.

First, when the movable body 29 rises and is located at a position close to the roll-shaped adhesive tape, the projection 26 serving as an arm is displaced to substantially the same height as the temporary bonding part 25 fixed to the casing 21. Therefore, the internal feeding tape portion T <b> 1 of the adhesive tape that passes between them is pulled out without contacting the temporary adhesive portion 25. Therefore, in this state, when the base 21 is pressed down integrally with the movable body 29 by an elevating device (not shown), the external feeding tape portion T2 is pressed by the pressing surface 30 formed on the lower surface of the front block 29A of the movable body 29 to be covered. It is adhered to the patch. Then, by continuing to press, the adhesive tape can be attached to the object to be transported by the transport device by a predetermined length.

Next, at the time of cutting, the movable body 29 is relatively lowered so that only the casing 21 is raised and moved in a direction away from the roller-shaped adhesive tape R. As a result, the protruding portion 26 serving as an arm is displaced in the hanging direction with respect to the temporary bonding portion 25, so that a part of the internal feeding tape portion T <b> 1 passing therebetween is bent and bonded to the temporary bonding portion 25. Can be.

Further, by moving up only the casing 21 while keeping the movable body 29 as it is (relatively descending the movable body 29), the blade portion 32 is pressed against the tensioned tape to cut the tape. After the cutting, the movable body 29 is raised to approach the roller-shaped adhesive tape R, and the tip of the cut tape is projected below the pressing surface 30 of the movable body 29 to prepare for the next sticking.

FIG. 9 shows an embodiment in which the apparatus of the above embodiment is of a manual type, and the movable body 29 is urged downward by a spring 40. The movable body 29 is provided with a pair of long holes, the front hole 41 is long, and the rear hole 42 is short. Guide pins 43 and 44 fixed to the casing 21 serving as a casing are fitted into the elongated holes 41 and 42, respectively.

As a result, the movable body 29 is
1, 42 and guide pin 4 fixed to casing 21
By the engagement with 3, 44, the downward force applied to the casing 21 can be adjusted so that the movable body 29 can be moved up and down in parallel or tilted forward. Therefore, this device functions in the same manner as in the previous embodiment and can tilt the movable body 29 obliquely, so that it is possible to further easily press the tip of the external feeding tape portion T2.

[0025]

According to the adhesive tape feeding device of the present invention, the pressing position of the movable body with respect to the guide edge is substantially the same as the guide edge, and the pressing position of the pressing surface of the movable body on the rear side in the tape withdrawing direction. Since the portion is displaced to a cutting position where the portion is outside the guide edge, and a portion on the rear side in the tape pull-out direction of the pressing surface is displaced to a standby position where the portion is inside the guide edge,
Adhesion and cutting of the tape can be easily performed only by the relative displacement between the guide edge and the movable body, and the feeding structure is extremely simplified, the reliability is improved, and the tape is suitable for industrial mass production. Also, anyone can automatically attach and cut the tape with a simple operation just by moving the casing. Also, since the rear end side of the movable body is displaced inward from the guide edge after cutting, the pressing surface separates from the derived tape, so that the tape is not repeatedly adhered at the standby position and repeatable tape with good reproducibility Can be attached.
