Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a tape applying device for applying an adhesive tape to the seam of a box body and a lid for packing, for example.

[Conventional technology]

Kraft adhesive tape that is generally wound into a roll (adhesive tape for packing, especially paper whose base is paper)
In some cases, in order to facilitate unwinding at the time of use, the non-adhesive surface side is subjected to a peeling treatment such as silicon processing.

Using such tape, for example, as shown in FIG. 5, a seam 39 between the main body of the box 27 and the lid may be attached with an adhesive tape for packing.

In this packing operation, the craft adhesive tape 24 is conventionally unwound and attached to the seam 39 while being unwound manually. At the final end thereof, the non-adhesive surface 40 is laminated so as to be overlapped, or as shown in FIG.
Or the adhesive surfaces are stuck together as shown in FIG.

[Problems to be solved by the invention]

In the conventional packing operation described above, when the final end is overlaid on the non-adhesive surface, there is a problem that the non-adhesive surface is peeled off easily because the non-adhesive surface is subjected to a peeling treatment such as silicon processing.

In particular, when the box is made of Styrofoam, the adhesive strength of the adhesive tape is weak. Therefore, if the overlapped portion is peeled off, it will be peeled off over the entire circumference of the box during transportation, and there is a problem that it cannot be used for packing.

The final end shown in FIG. 6 and FIG. 7 is made in consideration of the ease of peeling of the above-mentioned pasting, but for example, when packing a box (tor box) containing fish etc. However, since water leaks from the seams, it cannot be said that packing is complete, and when the adhesive surface gets wet due to leaked water, the adhesive strength is extremely reduced and peels off over the entire circumference of the box.

The present invention is intended to provide a tape sticking device that enables stacking and completes packing even if it is like a tor box without water leakage and mechanically carries out packing work. is there.

[Means for solving problems]

That is, the present invention is provided with a rotary table, and has a polishing roller at the tip end that abuts on the side surface of an adherend placed on the rotary table and rolls, and the movement of the abrading roller that abuts on the adherend and rolls. A swinging arm is provided, and a drive device is provided for removing the peeling treatment agent on the non-adhesive surface of the adhesive tape by rotating the polishing roller for a certain period of time.

[Action]

With this configuration, at the beginning when the adhesive tape is attached to the object to be adhered placed on the rotary table,
The polishing roller is rotated by a driving device to remove the release treatment agent on the non-adhesive surface. After that, the rotation of the polishing roller is stopped, the rotary table is rotated, and the polishing roller pulls out the adhesive tape and presses the adhesive roller against the side surface of the object to be adhered by the arm and sticks it. Then, the final end is overlaid on the non-adhesive surface from which the silicon has been removed.

〔Example〕

An embodiment of the present invention will be described in detail below. In FIGS. 1 and 2, reference numeral 1 is a rotary table. The rotary table 1 is axially supported by a bearing 29 attached to a frame 28. 30 is a lifter for adjusting the height of the rotary table. The rotary table 1 is rotated by the drive pulley 15 inscribed in the flange 1. Reference numeral 31 is a motor for rotating the drive pulley 15, and 32 is a friction ring for obtaining a frictional force.

Reference numeral 2 denotes an arm that is swingably provided about a shaft 35, and a polishing roller 3 is provided at the tip of the arm. The shaft 35 is supported by a bearing 36, and the lifter 37 adjusts the height of the arm 2. A holder 34 is attached to the tip of the shaft 35 and holds the packing adhesive tape 24. Sticking object
27 is mounted on the turntable 1 and fixed by the fixing metal fitting 26 by the operation of the handle 21. Reference numeral 38 denotes a spring, which applies an elastic force to the arm 2 so as to press the polishing roller 3 against the side surface of the fixed object 27 to be adhered. Reference numeral 8 is a motor for driving the polishing roller, which rotates the polishing roller 3 via pulleys 9, 9 and a belt 11. A cutter arm 4 is attached to the arm 2 via a support shaft 5, and a pressing roller 6 and a cutter 7 are attached to the tip thereof. 12,13,
14 is a guide roller for the pulled-out adhesive tape 25,
It is attached to the arm 2.

The drive pulley 15 and the motor 31 are swingably supported via a support shaft 16 as shown by an arrow.

That is, the arms 17 and 17 are connected by the pin 18, and swing with the swing of the arm 2. Due to this swing, the drive pulley 15 and the flange 1'of the rotary table come into contact with or separate from each other, and the rotary table 1 is rotated or stopped accordingly. The elastic force of the spring 20 is constantly urged in the direction in which the drive pulley 15 contacts the flange 1 '. Reference numeral 19 is a long hole for effectively utilizing the elastic force of the spring 20.

The operation of the present embodiment configured as above will be described below.

The adhesive tape 25 is pulled out to the polishing roller 3 through the guide rollers 12, 13 and 14. Then, the worker grips the cutter arm 4 to operate it.

First, before starting the work, the arm 2 is pushed against the elastic force of the spring 38 so as to be separated from the rotary table 1. Therefore, the drive pulley 15 is separated from the flange 1'and the rotary table 1 is stopped.

In this state, the adherend 27 is set on the rotary table 1. Next, when the worker swings the arm 2 toward the rotary table 1, the motor 8 is automatically turned on by the swing of the arm 2 and the polishing roller 3 is stopped after rotating for a predetermined time. The rotation direction of the polishing roller 3 is the direction in which the adhesive tape 25 is pulled out.

Then, the worker finds that the rotating polishing roller 3 is an object to be adhered.
Adjust the amount of swing of arm 2 so that it touches the side of 27 lightly (the adhesive tape 25 will be torn off if pressed too hard), and with the end of the adhesive tape 25 lightly adhered to the side of the adherend 27 Then, the rotating polishing roller 3 is rubbed against the adhered surface of the adhesive tape 25, and the release treatment agent on the non-adhesive surface is removed by polishing. Then, after the rotation of the polishing roller 3 stops, when the hand is released from the cutter arm 4, the polishing roller 3 is appropriately pressed against the side surface of the adherend 27 by the springs 38 and 20, and the drive pulley 15 causes the flange 1 to move. ′
And the rotary table 1 gently rotates.

This state is shown in FIG. In the figure, the arm 2 is swung by the elastic force of the spring 38 following the movement of the polishing roller 3 that is in contact with the side surface of the rotating adherend 27. In this case, the polishing roller 3 pulls out the adhesive tape 25 and presses it against the adherend.

Then, as shown in FIG. 3, when the attachment comes to the final end, the worker grips the cutter arm 4 and pushes it in the direction of 4 ', so that the arm 2 moves to the 2'side and the drive pulley. When the rotary table 1 is stopped by separating 15 from the flange 1'and the cutter arm 4 is further pushed to the position shown in the figure, the pressing roller 6 causes the object to be adhered.
Pressed on the side of 27, adhesive tape in the first stage
Roller 6 is applied to the part of 25 non-adhesive surface from which the release treatment agent has been removed.
Due to this, the adhesive tape 25 is strongly overlaid. Then, the adhesive tape 25 is cut by the cutter 7.

Further, the adhesive height of the adhesive tape 25 may vary depending on the shape of the adherend. In this case, the lifters 30 and 37 are operated to adjust the heights of the rotary table 1 and the arm 2.

Further, the contact between the drive pulley 15 and the flange 1'is made by the swing amount of the arm 2, so that a stopper is provided so as to be positioned on the rotary table 1 depending on the size of the adherend 27. Then, the adherend 27 is automatically carried onto the rotary table 1 by a conveyor or the like.

In this way, by sticking the end of the adhesive tape on the portion from which the peeling treatment has been removed, the adhesive tape is firmly adhered.

[Effect of device]

As described in detail above, according to the present invention, a polishing roller that is placed on a rotary table and abuts on a side surface of an object to be rotated and rolls is provided at the tip, and a rotating adherend and an abutting object An arm that swings according to the movement of the rolling polishing roller is provided, and a drive device is provided for rotating the polishing roller for a certain period of time to remove the release treatment agent on the non-adhesive surface of the adhesive tape. It is possible to remove the peeling treatment of the non-adhesive surface of the pressure-sensitive adhesive tape with a polishing roller, and laminate the final end of the pasting onto the non-adhesive surface from which the above-mentioned peeling treatment has been removed.

As a result, the pasted portion of the final end is firmly attached and is not peeled off. For example, even if the adherend is a piece of styrofoam where the adhesive tape is easily peeled off, it does not peel off because the lapped portion at the final end is firmly attached, greatly improving the packing property. I was able to.

Further, since the worker only needs to operate the handle, the packing time and labor can be shortened, and some practical effects are excellent.
