DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape sticking apparatus, and more particularly to a method of sticking a tape to an end face of an article wrapped with a wrapping paper to fix the wrapping of the article. The present invention relates to a tape attaching device suitable for use in attaching.

[0002]

2. Description of the Related Art When wrapping a product in a cylindrical shape such as a raw material in which a long sheet-like material is wound into a cloth, first, the wrapping paper wider than the axial length of the raw material is used. Wrapped in a roll along the circumferential direction of the web, and then wrapped the wrapping paper that protruded from both ends of the web into a cylindrical shape on both ends of the web (referred to as "chrysanthemum fold" or "gathering") It may be performed by sticking a seal (label) or a tape on the gathering portion.

At this time, as shown in FIG.
In the case where the diameter is large, the seal cannot be fixed tightly only by sticking the seal at the center of the gathering portion 2, and there is a concern that the packaging may be loose. for that reason,
As shown in the figure, an adhesive tape T, T longer than the diameter of the web 1
May be fixed in such a manner that the end portions T ′ and T ′ are attached to the side surface 1 b of the web 1 in a cross shape.

Conventionally, as an apparatus for performing the above-described tape application, an apparatus disclosed in Japanese Patent Publication No. 54-714, "Packaging Tape Application Apparatus" has been provided. This conventional tape sticking device has a tape holding piece that reciprocates in a form crossing the end face of the raw material in the diameter direction (vertical direction). After gripping one end of the adhesive tape with this tape holding piece, the adhesive tape is pulled out by moving linearly across the proximity position of the raw end face to face the raw end face, and then the adhesive tape is removed. The pressure-sensitive adhesive tape is pressed against the end face of the raw material, that is, the gathering portion, and is cut in the middle of the pressing operation so that the adhesive tape is stuck to the gathering portion in the diameter direction.

[0005]

By the way, according to the above-mentioned conventional apparatus, the tape can be stuck as described above, but it has the following disadvantages. That is, after the adhesive tape has been attached as described above, the tape holding piece returns to the top once and then goes to get the tape in order to pull out the adhesive tape to be applied next. Then, the cut end (pull-out end) of the adhesive tape is grasped again.

However, although the drawn end of the cut adhesive tape is temporarily guided by the guide plate,
So to speak, it is free. Therefore, for example, in the case where the drawn end of the adhesive tape is warped, there arises a problem that the tape holding piece that has received the drawn end cannot grip the drawn end.

After cutting the adhesive tape T to a predetermined length,
When the pressure-sensitive adhesive tape is pressed against the gathering portion of the raw material, the pressure-sensitive adhesive tape is bonded to a portion corresponding to the end face of the raw material, but the end T ′ of the adhesive tape T is cut off. It is left as it is. For this reason, the end T 'of this adhesive tape is thereafter
This is not only inefficient in achieving full automation, but also involves safety concerns.

The present invention has been made in view of the above circumstances, and realizes a complete operation in the above-described tape attaching operation, thereby enabling a tape to be attached reliably, efficiently and safely. An object is to provide a sticking device.

The first holding portion draws out the adhesive tape while performing a circular motion, and when rotated 180 °, the adhesive tape faces almost the center position of the end face of the workpiece. When the adhesive tape is pulled out by the rotational movement of the tape holding device, the adhesive tape receives a pulling force in the width direction thereof. However, since the guide roller supporting the adhesive tape is configured to be able to swing, it responds smoothly. The portion of the pulled-out adhesive tape corresponding to the other tape holding device is gripped by the other tape holding device. Thereafter, the cutter is operated to cut the adhesive tape, and the cut adhesive tape is pressed against the end surface of the workpiece with the pressing surface to attach the adhesive tape. At this time, even after the adhesive tape is cut, the drawn end is firmly held by the first holding portion of the other tape holding device. Next, when pulling out the adhesive tape, the first holding portion of the other tape holding device pulls out the cut end of the tape. That is, the cut end of the adhesive tape is always held by the first holding portion of one of the tape holding devices.

In the tape sticking apparatus according to the present invention, both ends of the adhesive tape stuck to the end face of the work are automatically bent and stuck on the side face of the work by the guide portions of the two tape holding devices. Is done.

In the tape sticking apparatus according to the third aspect, an operation of sticking the tape in a cross shape can be automatically performed.

In the tape applying apparatus according to the fourth aspect, the tape can be applied to both surfaces of the workpiece at one time.

In this embodiment, although not shown, the tape applying devices having the same structure as the tape applying device 10 are opposed to each other, that is, the pressing surfaces 55a of the tape applying devices are opposed to each other. Are provided facing each other.

Next, the tape sticking apparatus 1 having the above configuration
The operation of 0 will be described with reference to FIG. 1 and FIGS. In the present embodiment, in the case where the processed product is a cylindrical raw material for which packaging has been completed, and an adhesive tape is attached in a cross shape to both end surfaces, that is, the gathering portion of the wrapping paper as shown in FIG. Will be described. In addition, as described above, the present apparatus is configured such that the two tape pasting apparatuses 10 are provided to face each other. However, since the operations of both apparatuses are exactly the same, Only the operation 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 the gathered surface is opposed to the pressing surface 55 a of the tape applying device 10. The support base 85 is usually attached to a line conveyor (not shown) that transports the web 1,
The wrapped web 1 is conveyed on the line conveyor from the previous wrapping process and is automatically placed on the support 85. The raw web 1 has various diameters, but the upper and lower bases 88 allow the axial center of the raw web 1 to be
The first and second rotating shafts 17 and 31 are adjusted so as to be on the same axis. In the fully automatic process, the outer diameter of the web 1 is measured in advance by an appropriate means, and the height of the support 85 is automatically set based on the data.

The frame 13 is located at the outermost position of the movable pedestal 12 as shown in FIG. Adjustment of the position of the frame 13 so as to correspond to the axial length of the web 1 is performed by sliding the movable pedestal 12 on the support pedestal 11. In addition, a pair of tape clamps 45
A and 45B are located vertically as shown. The tape roll holding roller 68 of the tape holding unit 62
A tape roll TR is set in FIG. The cut end of the adhesive tape T fed out from the tape roll TR is in a state at the time when the operation of attaching the tape to the immediately preceding material has been completed, that is, the tape holding tool 4 positioned above.
5B is held by the first holding portion 48 of FIG. In this state, the adhesive surface Ta of the adhesive tape T faces the side on which the web 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. At this time,
The distance between the tape holders 45A and 45B, that is, the distance between the inner end surfaces 45a and 45a is set to be slightly larger than the diameter of the web 1.

To attach the adhesive tape T to the end face of the raw material 1 from the above initial state, first, as shown in FIG.
The rotation frame 22 provided with the two tape holding members 45A and 45B is rotated by 180 ° around the first rotation 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, one of the tape clamps 45
The adhesive tape T having the cut end sandwiched by B receives a tensile force in its own width direction as shown in FIG.
The pulling force at the time of feeding the adhesive tape T is first applied to the guide roller 63. Since the guide roller 63 is provided on the support frame (small) 74 rotatable by the shaft 75, The roller 63 receives the force in the oblique direction and swings as shown in the figure to be inclined obliquely. At the same time, the tape roll T
The R and the tension roller 69 are also inclined integrally with the guide roller 63, so that the adhesive tape T can be smoothly fed out.

Here, the feeding of the pressure-sensitive adhesive tape T will be further described. The convex belt 79 is formed on the guide roller 63. This is because the adhesive tape T that has been subjected to the lateral tensile force as described above is
This is because the edge action of the convex band 79 reliably prevents the escape in the width direction 3. Further, 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 by the studs 71, 71,... (FIG. 4) provided on the opposite side to the cap 73. . Therefore, by adjusting the tightening force of the cap 73, it is possible to apply a braking force to the rotation of the tape roll TR, whereby the tension at the time of feeding the adhesive tape T can be appropriately adjusted.

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

FIG. 6 shows a state in which the rotary frame 22 is rotated by 180 ° in a state where the one tape holding member 45B holds the adhesive tape T as described above. In this state, the adhesive tape T is still in the first holding portion 4 of the tape holding device 45B.
8 alone. The other tape clamp 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 holding member 45B and the guide roller 63, and the adhesive tape T
Fits in both the first and second tape holding portions 48 and 49 of the tape holding device 45A.

Next, the tape holding device 4 that is currently at the bottom
The adhesive tape T held by only the first holding portion 48 of 5B is further removed from the second holding portion 49 (holding pieces 52 and 53) of the tape holding device 45B and the tape holding device 45A located above. First holding portion 48, second holding portion 4
9 as well. That is, in this state, all the tape holding portions hold the adhesive tape T.

After that, the cutter 54 of the tape holder 45A located above is projected to the adhesive tape T side to cut the adhesive tape T. After the adhesive tape T is cut, the first holding portion 48 and the second holding portion 49 of the lower tape holding device 45B, and further the upper tape holding device 45A.
The clamping operation of the second tape clamping device 49 is released. That is, the cut end of the adhesive tape T is held by only the first holding portion 48 of the upper tape holding tool 45A. At this time, it is cut and both tape clamps 45 are cut.
A of the adhesive tape T between A and 45B is such that the adhesive surface Ta thereof has a holding piece 52 of the tape holding tool 45A and a tape holding tool 4.
By being adhered to the holding pieces 50 and 52 of 5B, the tape holding tool 45A and 45B are held between them.

Thereafter, as shown in FIG.
When the whole is slid on the moving pedestal 12 toward the web 1 (the moving pedestal 12 is not moved), the adhesive surface Ta of the adhesive tape T comes into contact with the end face of the web 1 as shown in the figure.
When the frame 13 is further moved in the same direction from this state, as shown in FIG. 8, both the tape holding members 45A and 45B holding the both ends of the adhesive tape T are brought into contact with the side surface 1b of the material 1.
Side, that is, into the peripheral body surface side. By this operation, both ends of the adhesive tape T held between the tape holding members 45A and 45B are pulled forward (moving direction) by the tape holding members 45A and 45B. The adhesive force of the pressure-sensitive adhesive tape T stuck to the base material 52 loses its tensile force and separates from the holding pieces 50 and 52.
Then, the adhesive tape T separated from the holding pieces 50 and 52
Are guided by the inner end surfaces 45a of the moving tape holders 45A and 45B so as to be tilted toward the side surface 1b of the raw material 1, and are adhered to the side surface 1b. Also, by moving the frame 13 toward the web 1 in this manner,
Eventually, the pressing surface 55a of the pressing member 55 provided between the tape holding members 45A and 45B comes into contact with the end surface 1a (FIG. 2) of the web 1, and the adhesive tape T is brought into contact with the end surface 1a.
Press enough. Thereby, the attachment of the adhesive tape T to the end face 1a of the raw material 1 is completed.

When the adhesive tape T is to be further applied (for example, in a cross shape) to the end face 1a, the frame 13 is once retracted from the above state as shown in FIG. Thereafter, as shown in FIG. 10, the raw web 1 is rotated on the support base 85 by 90 ° in the circumferential direction. The rotation of the web 1 can be performed by driving the support roller 86 by operating the motor 87. Then, together with the above operation, the rotary frame 22 is rotated by 180 ° as shown in the figure, this time in the direction opposite to the previous direction. The reversal of the rotating frame 22
This is performed by operating the rotary frame driving actuator 19 to drive the pinion 18 via the rack gear 20. Also in this case, since the cut end of the adhesive tape T is clamped only by the first clamping portion 48 of the tape clamping device 45A, the turning operation with the adhesive tape T clamped is possible. In this case, the guide roller 63 and the tape holding portion 62 are inclined in the tape pull-out direction as shown.

When the rotary frame 22 is turned 180 ° and the tape holder 45A holding the adhesive tape T is located on the lower side and the other tape holder 45B is located on the upper side, the tape holder 45B is provided. The adhesive tape T is cut by the cutter 54, and then the cut adhesive tape T is cut in the same manner as described above with reference to FIGS.
Is adhered to the end face 1a of the material 1. by this,
Adhesive tapes T, T are attached to the end face 1a of the raw material 1 as shown in FIG. The same operation as described above is simultaneously performed on the other end face (not shown) of the web 1 by the other tape sticking device installed corresponding to the end face.

When the outer diameter of the web 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, 27 further rotate via bevel gears 34 and 35. As a result, the moving block 46 that constitutes the base end of the tape holders 45A and 45B is formed.
Move along the guide rods 26, 26, respectively, and the separation distance between the tape holding members 45A, 45B is adjusted.

As described above, according to the tape sticking apparatus 10, even after the portion of the adhesive tape T to be attached to the raw material 1 is cut off by the cutter 54, the cutting of the adhesive tape T fed from the tape roll TR is continued. The first holding portion (holding piece 50,
51) to keep the pinched state all the time. Therefore, the operation of feeding out the pressure-sensitive adhesive tape T to be applied next can be reliably performed without error.

Further, the tape holding members 45A, 45
B, the inner end surface 45a is formed as a guide portion in which both ends of the cut adhesive tape T are folded into the side surface 1b of the raw material 1, so that both end portions of the adhesive tape T can be reliably and automatically formed on the side surface 1b. Affixed to Therefore, there is no need to attach these both ends manually, and the fully automatic operation of this tape attaching operation can be completed.

In the above embodiment, after the adhesive tape T is cut by the cutter 54, when the cut adhesive tape T is applied, all of the holding portions other than the first holding portion of the tape holding device 45 positioned above are cut off. The case where the opened and cut adhesive tape T is held between the two tape clamps by its own adhesive force has been described.

Then, the frame 13, that is, the tape clamps 45A, 45
Although B is configured to be moved with respect to the workpiece (raw material 1), a configuration may be employed in which the workpiece is moved with respect to the tape clamp. Further, in the embodiment, the workpiece to which the adhesive tape T is to be attached has been described as the cylindrical raw material 1. However, the workpiece may be of another shape, such as a box. Further, when the workpieces match with the original fabric as in the embodiment, the adhesive tape T may be affixed, for example, with three adhesive tapes at 60 ° intervals instead of the cross shape as described above. In that case, the support table 8
The rotation amount of the support roller 86 of No. 5 may be appropriately adjusted so that the web 1 is rotated by a predetermined angle (in this case, 60 °) by one operation. Further, in the embodiment, the configuration has been described in which both the tape holding members 45A and 45B rotate in the vertical plane. However, in the tape attaching device according to the present invention, both the tape holding devices 45A and 45B rotate in the horizontal plane. Such a configuration may be adopted.
