Description

  The present invention relates to a device for attaching a sealing tape to a bag body, which attaches a sealing tape having an adhesive layer capable of closing an opening or the like of the bag body to the bag body.

The sealing tape is often used to close the opening of the bag after the contents are stored in the bag with respect to the opening of the bag.
For example, after the product is put in a plastic bag or a bag with a handle when the product is sold, the opening of the bag is closed with a sealing tape having an adhesive layer such as cellophane tape so that the product does not spill out. It is.
Therefore, for example, when shopping, etc., products are put in a bag with a cash register etc., and the openings are closed one by one with a tape having an adhesive layer, and a long sealing tape is wound around. This tape is used as a sealing tape by cutting the required amount from the wound tape one by one according to the amount used.

For this reason, every time this tape is used, it is necessary to cut and paste an arbitrary length one by one.
Therefore, it is very troublesome to sequentially seal a large number of bags and seal them with an adhesive tape.
In particular, in order to block each, it is necessary to attach it to an arbitrary position accurately, and the effort is enormous.
Further, an absorbent article such as a medical pad is packaged with a packaging sheet, and the opening is sealed with a sealing tape. The sealing tape further includes a different adhesive layer, and the first pressure-sensitive adhesive layer And a second pressure-sensitive adhesive layer and a third pressure-sensitive adhesive layer, the opening is closed in advance by the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer, and the second pressure-sensitive adhesive among these There is also a sealing tape for opening once by peeling off the layer and then resealing with a third pressure-sensitive adhesive layer in order to re-seal the opening.

For example, the individual absorbent material shown in JP2013-75012A (Patent Document 1) is an individual absorbent material using the sealing tape.
As described above, there is a sealing tape for reattachment, but it is necessary to attach it to an arbitrary position on the packaging sheet.
For example, it is possible to prepare a large number of such sealing tapes and affix them one by one to the packaging sheet one by one, but this is extremely complicated and takes a lot of work.

In this way, if it is one or two per person, even if it takes some time, it will be acceptable to some extent.
However, for example, when selling fresh products and the like on the seller side in advance, with regard to the long sealing tape, the necessary amount is reduced from the wound tape to the required amount. It is necessary to cut the tapes one by one and close the openings one by one, which is very time consuming and requires complicated procedures.
For example, it is often used to sell cabbage, tomatoes, fruits or the like in a bag body, but this bagging operation is extremely time-consuming.

In this case, for example, when the product is sealed with an adhesive tape at the time of sale, such as medical goods, and once opened, the contents are used, and the contents after storage are enclosed in the bag again and discarded, etc. As shown in Patent Document 1, there is a configuration using a sealing tape that enables re-sealing.

In other words, the first adhesive part 15 that is stuck on the peeling part 11 of the sealing tape 1 is peeled off and exposed, and the bent first adhesive part 15 is peeled off and exposed.
In this case, since the tip portion of the sealing tape 1 having the first adhesive portion 15 has the tear tape 12, this portion can be easily pinched so that the first adhesive portion 15 is exposed. Can be peeled off from the peeling portion 11.
In this way, the first adhesive portion 15 is exposed, and the opening portion of the bag A can be sealed using the first adhesive portion 15.

FIG. 4 is a diagram showing an example of a flow of attaching the sealing tape of the device for applying the sealing tape to the bag body according to the present invention to the bag body A. FIG.
First, the long tape of the sealing tape 1 is sent to the main body roller 3 using the feed roller 4.
The long sealing tape 1 has a first adhesive portion 15 and a second adhesive portion 16 at both ends in the short direction of the roller 2 of the long sealing tape, respectively. 1 is a sealing tape 1 in which the first adhesive portion 15 is folded and overlapped with the peeling portion 11 after having the peeling portion 11 on the surface.

Such a tape 1 is fed and cut to the required width by the main body roller 3 and then attached to the bag A.
The roller 2 of the long sealing tape 1 has a second adhesive portion 16 exposed. A separate tape 17 is attached to the surface of the second adhesive portion 16. In the case where a drum around which the roll 2 of the long sealing tape 1 is wound is formed and sent from the drum to the main body roller 3, the second adhesive portion 16 is moved to another part by the release tape 17. Can be sent without sticking to.

Thus, the sealing tape 1 is sent from the roller 2 of the long sealing tape 1 using the feed roller 4, and sent to the main body roller 3 using the motor M or the like.
In this case, the sealing tape 1 is sent to the main body roller 3 in a state where the second adhesive portion 16 of the sealing tape 1 faces the outside of the feed roller 4.
Further, the peeling tape 17 adhered to the second adhesive portion 16 is removed at the time of the feeding, and the take-up roller 5 takes up the tape.

The main body roller 3 feeds the sealing tape 1 by intermittently rotating.
That is, when the main body roller 3 rotates, the rotation stops between rotations, and the main body roller 3 rotates intermittently.
For example, after a slow rotation operation of about 0.1 to 1 second, the rotation is stopped for about several seconds, and further, a slow rotation operation of about 0.1 to 1 second is performed. Rotating intermittently by repeating the rotating operation and stopping.

The rotation of the main body roller 3 is controlled by a motor M or the like.
Such a main body roller 3 has a suction portion 31 at the position of the sealing tape 1.
Therefore, the sealing tape 1 is sucked from the suction portion 31 so that the sealing tape 1 is in close contact with the main body roller 3 and is sent in close contact with the main body roller 3.
A large number of suction portions 31 of the main body roller 3 are sequentially provided in the rotation direction in which the sealing tape 1 is fed.

In this way, the sealing tape 1 fed in the attracted state by the main body roller 3 is further cut into an arbitrary width by the cutting portion 32.
That is, even the sealing tape 1 of the form shown in FIG. 1 is cut at the cutting portion in order with an arbitrary width, so that the sealing tape 1 with a short width shown in FIGS. 2 and 3 is obtained.

The scale-like sealing tape 1 can be cut, and individual cut sealing tapes 1 having an arbitrary length can be formed.

Each of the cut sealing tapes 1 is sucked by the main body roller 3 by the suction portion 31 and is sent along with the rotation of the main body roller 3.
Therefore, it is desirable that the suction portion 31 of the main body roller 3 has the suction portion 31 for each sealing tape 1 to be cut at a predetermined length.
For example, the suction part 31 has a hole 310 for suction, and the sealing tape 1 is sucked and sucked from the hole 310.

Alternatively, it may have another suction or adsorption structure.
By comprising in this way, the elongate sealing tape 1 can be cut | disconnected by arbitrary width | variety, and each individual sealing tape 1 of a predetermined | prescribed width | variety can be formed.
When such a sealing tape 1 is further fed, it merges with the conveyor 6 etc. to which the bag A is fed.

The sealing tape 1 is attached to the bag body A by adhering the second adhesive portion 16 of the sealing tape 1 to a necessary portion of the bag body A at this junction.
In this case, the suction of the suction part 31 is stopped at the joining point, the sealing tape 1 can be removed from the main body roller 3, and the second adhesive part 16 is adhered to the bag body A at an arbitrary position of the bag body A. Adhesive tools such as pressing the sealing tape 1 to an arbitrary position of the bag A or pressing the second adhesive portion 16 of the sealing tape 1 to an arbitrary position of the bag A Therefore, it has the adhesive machine 7 etc., and can perform an adhesion process.

The sealing tape 1 can be sequentially attached to an arbitrary position of the bag A by sending the sealing tape 1 configured in this way.
Therefore, the bag A having the sealing tape 1 shown in FIG. 2 can be easily manufactured.

FIG. 5 is a view showing a part of an example of the main body roller 3, and is a view showing a state in which the main body roller 3 is provided with the holes 310 as the suction portions 31 in three rows sequentially in the rotation direction.
The suction is performed through the hole 310, and the sealing tape 1 is adsorbed to the hole 310.
The sealing tape 1 has a second adhesive part 16 and a peeling part 11 subsequent thereto, and has a first adhesive part 15 that is folded and overlapped with a part of the peeling part 11.

In such a state, the sealing tape 1 is sent to the roller 3 by the suction portion 31 while being sucked.
Therefore, the holes 310 of the suction portion 31 for sucking the sealing tape 1 of the main body roller 3 are examples having three rows in the width direction for each sealing tape 1 to be cut. An example is shown.

In this case, the number of rows is not limited to 3, but may be 2 rows, 4 rows, or two rows or more in a slightly shifted state instead of one horizontal row.
By configuring in this way, the long sealing tape 1 can be sent in close contact with the main body roller 3, and further, the sealing tape 1 is cut at a fixed length by the cutting portion 32, and each individual tape is cut. Even when the sealing tape 1 is obtained, the individual sealing tape 1 can be sent in close contact with the main body roller 3.

FIG. 6 shows an example of the state in which the main body roller 3 is being intermittently rotated while the sealing tape 1 having the cutting line 320 cut by the cutting part 32 as described above is sucked by the suction part 31. Show.
As shown in the figure, the individual sealing tapes 1 cut along the cutting line 320 are sucked through the holes 310 of the suction part 31 and sequentially fed to the main body roller 3 in the suction state.
