Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape applying device with a tab for automatically applying an adhesive tape having a non-adhesive tab portion on an adhesive surface to an object moving in a predetermined direction. This tab attaching device can be used in automatic packing machines such as cardboard boxes.

[0002]

2. Description of the Related Art When an adhesive tape is attached to an adherend such as a cardboard box for the purpose of, for example, packing or sealing, the adhesive tape is attached in advance in order to facilitate removal when the attached adhesive tape is opened. It is known to form a non-adhesive tab portion on a surface. The pre-forming method of such a tab portion is
The method is roughly classified into a method of attaching a tab film, which is another member, to a desired portion of the adhesive tape, and a method of partially non-adhering the adhesive tape itself.

As a pasting device for automatically pasting an adhesive tape with a tab having a tab portion formed by the former tab film attaching method to an adherend such as a cardboard box, it is disclosed in, for example, US Pat. No. 4,238,269. There is known a type in which a tab attachment device having a movable cassette holding a plurality of tab films is incorporated into such a well-known adhesive tape attaching device. As shown schematically in FIG. 12, this type of tabbed tape applicator is installed at a desired position on the adhesive surface of an adhesive tape 2 fed from a tape supply roll 1 that stores an adhesive tape in a roll shape to a tape application section. A movable tab cassette 4 to which the tab film 3 is attached is provided.
The tab cassette 4 stacks and holds a plurality of tab films 3 which are cut and formed in a predetermined shape and size from a continuous body. In the tape application section, the adherend 5 such as a cardboard box moves along a predetermined track, and the tape supply roll 1
The adhesive tape 2 sent from is adhered to the adherend 5 by the tape applying roller 6. The adhesive tape 2 is automatically delivered from the tape supply roll 1 as the adherend 5 moves. A sensor 7 for detecting passage of the rear end portion of the adherend 5 in the moving direction is arranged at a predetermined position on the tape attaching portion,
In response to the detection of the passage of the rear end, the tab cassette 4 is rapidly moved in the direction of the adhesive tape 2 by the cassette driving means (not shown), and the tab film 3 is attached to the adhesive tape 2 in a stamp manner. The adhesive tape 2 with the tab film 3 attached thereto is cut together with the tab film 3 at a substantially central position of the tab film 3 by the cutter blade 8 at the tape adhering portion.
Therefore, the adhesive tape 2 to which the half-cut tab films 3 are attached is attached to both ends of the adherend 5 in the longitudinal direction.

As the latter partial non-adhesion processing method, production of an adhesive tape without applying an adhesive to the side edges is practically carried out.
It is disclosed in Japanese Patent Laid-Open No. 117764. A tabbed tape dispenser using a partially non-adhesive processing method is disclosed in Japanese Utility Model Laid-Open No. 63-37670. This tape dispenser is equipped with a bending guide for the side edge portion of the adhesive tape, and when the adhesive tape is pulled out, the side edge portion is automatically folded by the bending guide in the direction of the adhesive surface, and its own non-adhesive surface. The tab portion is formed by (back side).

A conventional tape applying device with a tab using the above-described method for attaching a tab film is a tab cassette capable of accommodating a predetermined number of tab films 3 cut and formed in advance into a predetermined shape and size. Since 4 is used, the number of adherends that can be adhered is necessarily limited in the case where continuous adhesion is performed on a large number of adherends 5 that move continuously. Frequent replacement of the tab cassette 4 is required to replenish the tab film 3, which impedes continuous operation of the device. When the length of the tab film 3 is changed in accordance with the size of the adherend 5 or the like, it is necessary to replace the tab film with a tab cassette accommodating tab films having different sizes. Furthermore, since the tab film 3 is attached to the adhesive tape 2 in a stamping manner, the feed speed of the adhesive tape 2, that is, the feed speed of the adherend 5 must be slowed down, which speeds up the working speed. Has become a bottleneck. Further, due to the preparatory work for cutting and forming a large number of tab films 3, the cost for tab attachment increases.

Further, the known adhesive tape having a side edge portion to which the adhesive is not applied increases the material cost and complicates the inventory control, so that the tape sticking of the automatic packing machine which requires an extremely large amount of the adhesive tape is required. Not suitable for use in equipment. Further, the tape dispenser described above is advantageous in terms of cost because ordinary adhesive tape can be used and tab film is not used, but since tension maintenance of the adhesive tape in the folding guide portion is insufficient, for example, an automatic packing machine.

At the same time as this detection, the control device 105 is set so as to operate the first cylinder device 100 of the tab attachment device 32.

Further, the control means of the first embodiment of FIG. 1 is the box 1 for a point at a predetermined distance from the tape sticking head 24.
In addition to the detection means for detecting the passage of the sheet 6, that is, the sensor 118, the tab attachment device 32 from the passage of the box 16 at a predetermined point.
It further comprises a first time setting means for setting a time until the operation of is excited. When L <S + s, the sensor 11
Reference numeral 8 detects the passage of the front surface 16a of the box 16 at a predetermined position on the transport table 18, and supplies a signal to the control device 105. Therefore, the tab film 30 arranged on the rear surface 16c side of the box body 16 is attached to the adhesive tape 26 earlier than when L> S + s.

The first time setting means is capable of variously setting the time from the detection of passage of the box body 16 to the activation of the tab attachment device 32 according to the length of the box body 16. Consists of. The timer 120 is the tab attachment device 3
No. 2 sends a signal to the control device 105 of the first cylinder device 100 to set the activation timing of the first cylinder device 100. After the front surface 16a of the box body 16 has passed the sensor 118, the adhesive tape 26 is applied by the tape applying head 24.
Is attached to the box body 16 and the time T ₁ until it is cut is
It is calculated from the position of the sensor 118, the length of the box body 16, and the conveyance speed of the belt conveyor 22. In addition, after the tab film 30 is attached to the adhesive tape 26, the adhesive tape 2
The time T ₂ until 6 is cut is the belt conveyor 22.
It depends only on the transport speed of. So timer 120
By setting the time T = T ₁ −T ₂ from the detection of the passage of the box body 16 to the activation of the tab attachment device 32, the length of the box body 16 (L <S + s) is satisfied. It is possible to attach the tab film 30 to a desired position of the adhesive tape 26.

When L = S + s, the above L <S +
The operation timing is set in the same manner as in the case of s, but with the above configuration as it is, the adhesive tape 2 by the tape applying head 24 is used.
The cutting of 6 and the attachment of the tab film 30 by the tab attachment device 32 are synchronized with each other, and it becomes difficult to attach the tab film 30 of a desired length by stopping the adhesive tape 26. Therefore, a bypass roller (not shown) is installed between the cutter blade 40 of the tape sticking head 24 and each of the sticking rollers 74 and 76 of the tab sticking device 32 to increase the distance S, so that L <S + s is satisfied. A similar operation is possible.

As a result, the cutter blade 78 is pulled upward, and at the same time, the upper attachment roller 74 is moved downward to collide with the lower attachment roller 76, and the tab film 30 is attached to the adhesive tape 26. After returning to the state, the operation time until the cutter blade 78 reaches the state of cutting the tab film 30 is set variously, and a signal is sent to the control device 105. In this embodiment, the adhesive tape 26 is fed at a speed equal to the transport speed of the belt conveyor 22,
The length of the tab film 30 is determined by the setting of the operation time by the timer 122.

In the present invention, when the adhesive tape and the tab film are cut at the same time, the adhesive tape and the tab film are cut substantially at the central position of the tab film so that the rear end of one adhesive tape and the front end of the next adhesive tape are substantially cut. Tab films of equal length are attached. Therefore, in the first embodiment, the second time setting means (timer 122) absorbs the operation error of the adhesive tape cutting by the tape sticking head defined by the first time setting means (timer 120). Is possible.

The overall operation of the tabbed tape adhering device 12 having the above construction will be supplementarily described below with reference to FIG. First, in the initial state, the adhesive tape 26 pulled out from the tape supply roll 28 passes through the tab attachment device 32 as described above, and the tip end portion thereof is the tape application head 2.

At this time, the damper 152 damps the return speed of the yoke 140 as described above. To do. Thereby, the tab film 30 having a desired length is pulled out by the adhesive tape 26. And the yoke 14
When 0 is completely returned to the initial position and the upper attachment roller 134 and the lower attachment roller 136 are again arranged in the position of FIG. 11, the adhesive tape 26 is separated between the upper attachment roller 134 and the lower attachment roller 136. Tab film 30
Is cut by a cutter blade 138 fixed to the frame 130. The tab film pressing lever 176, which has forcibly loosened the tab film 30 in the ready state, releases the tab film 30 at the same time as the return operation of the yoke 140, so that the tab film 30 is not subjected to tension during attachment and cutting. It is put in a slack state. Therefore, since the tab film 30 is freely pulled out by the adhesive tape 26, the action of the damper 152 is assisted, and the tab film 30 having a desired and constant length is reliably attached to the adhesive tape 26.

Thus, the tape applying device 12 with tabs
No. 4 is a more advantageous device from the viewpoint of cost and maintenance by using a mechanical control means of inexpensive and simple structure, but like the tab attaching device 12 of the first embodiment, In the box packing machine 10, it is not possible to deal with the box 16 shorter than the predetermined length.

A tape passage having a width smaller than the entire width of the adhesive tape 26 is formed on the deviation shaft 192. Therefore, the adhesive tape 26 will inevitably be bent by contact with the guide ring 196 at least at one side edge as it passes through the narrow tape passage on the displacement shaft 192.

The brake roller 190 is a feed speed limiting roller having a well-known structure, and cooperates with the one-way tension roller 64 of the tape applying head 24 to pass through the bending movement path formed by the tape deviation member 188. A predetermined tension is always applied to the adhesive tape 26. The unidirectional tension roller 64 is a feed direction and feed rate limiting roller having a similar known structure, and rotates only in the direction of feeding the adhesive tape 26 to the attaching roller 36 (counterclockwise direction in FIG. 6). Therefore, due to the feed rate limiting action of the brake roller 190, the adhesive tape 26 between both rollers is
A predetermined tension is always applied. The magnitude of the tension can be adjusted by the degree of tightening of the nut 200 at the tip of the shaft 198 that connects the brake roller 190 to the column 186.

The operation of the above-mentioned tab attaching device 180 will be described below. First, as an initial state, a desired side edge (in the figure, one side) in a predetermined length (approximately equal to the tape path length from the tape deviation member 188 to the sticking roller 36) of the adhesive tape 26 pulled out from the tape supply roll 28 is drawn.
