The two suctions 52a and 52b are usually located on the upper standby line B or the lower standby line C, and are connected to the withdrawal end 2b of the standby raw material 6b and the cut end 2a of the raw material 6a being transferred. Is performed, the transfer from the upper standby line B to the transfer line A or from the lower standby line C to the transfer line A is performed as shown in FIG. This movement is performed by moving the vertical cylinder 43 downward from the upper standby line B or upward from the lower standby line C by the vertical cylinder 43 in a state where the suctions 52a and 52b are separated from each other, and positioned on the transfer line A. In the transfer line A,
After the ends 2a and 2b of the two webs 6a and 6b are connected, the horizontal cylinder 41 retreats from the transfer line A, and the vertical cylinder 43 moves to the upper standby line B or the lower standby line C.

Furthermore, the ends 2a, 2 of the two webs 6a, 6b
After the connection of b is made, both suctions 52a, 52b
Are moved away from the transfer line A once by the horizontal cylinder 41 in a state in which they are separated from each other, and then moved upward or downward by the vertical cylinder 43 to be moved to the standby lines B and C.

The blower 53 and the two suctions 52a,
A solenoid valve (not shown) is provided in the hose 54 to which the blower 52b is connected, and in a standby state of both the suctions 52a and 52b, the solenoid valve is turned off and the blower 53 is turned off.
When the suctions 52a and 52b are joined, the solenoid valve is turned on, the suction of the blower 53 is stopped, and the adhesive tape body 3 and the release paper 5 of the adhesive tape 2b of the raw material 6b in a standby state are stopped. Is released, and the adhesive tape 2b is transferred.

When the detection signal of the optical sensor 16 provided on the side of the material 6a being transferred is transmitted to the microcomputer, the control of the above means 10, 20, 30, 40, 50 is started. .

The connection device 1 according to the present invention is configured as described above, and its operation will be described below.

First, the material rolls 6b and 6a are set on the upper and lower material rolls 11b and 11a, respectively, and the lower material roll 6a is connected to the upstream feed roll 12a and the downstream fixed feed roll 13 of the transfer means 10. After that, it is wound around the main drum through the feeding roll 14 and the dancer roll 15.

On the other hand, the adhesive tape 2 of the upper web 6b is
It is pulled out to the position of both suctions 52a, 52b of the standby means 50 via the upstream feed roll 12a of the transfer means 10, and the drawn-out end 2b of the adhesive tape 2 is slightly peeled.

Then, the release paper 5 peeled off from the drawn end of the adhesive tape 2 is cut, and a bonding member 57 having a rectangular shape in a plan view is attached to the release paper 5 so as to be adsorbed to the upper suction 52a and to be attached to the lower suction 52a. The adhesive tape 2 is attracted to the suction 52b, the release paper 5 and the adhesive tape main body 3 are opposed to each other, and the upper material 6b is positioned on the upper standby line B.

Here, the release paper 5 is cut and the adhesive member 57 is cut.
The reason for sticking to one side is that the release paper 5 of the cut end portion 2a of the raw material 6a being transferred is stuck to the other side of the sticking member 57.

Next, the main drum is rotationally driven by the driving means, and the transfer of the lower raw material 6a is started. At this time, the dancer roll 15 is located at the position indicated by the solid line as shown in FIG.
The length has been increased.

When the remaining amount of the lower raw material 6a becomes small, the optical sensor 16 detects the remaining amount of the raw material 6a, and a detection signal is transmitted to the microcomputer.

The following control is sequentially performed by transmitting the detection signal. That is, at the same time when the moving feed roll 25 rises to pinch the web 6a, the movable blade 2 of the cutting mechanism 21
3 descends and cuts the web 6 a with the fixed blade 22.

At this time, the dancer roll 15 rises from the position indicated by the solid line to the position indicated by the chain line. Dancer roll 15
As the adhesive tape 2 is increased by the rise, the adhesive tape 2 is transferred to the processing section D on the downstream side.

On the other hand, while the dancer roll 15 rises from the position indicated by the solid line to the position indicated by the chain line, the following operation is instantaneously performed in the moving means 40 and the standby means 50.

First, the vertical cylinder 43 of the moving means 40
Operates, and the air chuck 51 descends from the upper standby line B to the transfer line A.

Then, as shown in FIG. 4, the pressing member 32 having a V-shaped tip is lowered and the adhesive tape 2 is made substantially V-shaped by the moving feed roll 25, that is, in the opposite direction to the transfer direction, that is, as shown in FIG. Along the transfer line A, the sheet is returned to the sheet 6a.

Here, the reason why the cut end portion 2a of the raw material 6a is V-shaped and returned to the raw material 6a side is that the raw material 6a is stored in a wound state, so that the raw material 6a is cut. End 2a
Has a winding habit, and by this winding habit, the raw fabric 6a
Is attached to the adhesive surface 57a of the attaching member 57 that is being sucked by the upper suction 52a in the standby state, so that the cut end 2a cannot be polymerized exactly.

As shown in FIG. 5, the position at which the cut end 2a of the web 6a is moved backward is
a so that the cut end 2a of the sheet feeder 2a can be overlapped with the separated end 2b of the raw material 6b in a standby state.
b.

The release paper 5 at the cut end 2a of the raw material 6a
Is the withdrawal end 2b of the standby web 6b in a separated state.
When there is a gap between the release paper 5 and the release paper 5, the adhesive member 57 and the adhesive tape main body 6b of the cut end 2a of the raw cloth 6a are bonded to each other. 5 and 5 cannot be peeled off continuously.
This will hinder the continuous transfer of a and 6b.

Accordingly, the cut end 2a of the material web 6a during transfer
Needs to be located at the inner side of the drawn-out end 2b of the standby web 6b, at a position where it can be overlapped with the drawn-out end 2b.

Next, both suctions 52a and 52b are moved in a direction approaching each other, and both suctions 52a and 52b are moved.
b are joined to each other, and both suction
a and 52b are pressed against each other.

Then, as shown in FIG. 6, the adhesive tape main body 3 at the cut end 2a of the raw web 6a being transported is superimposed on the adhesive tape main body 3 at the drawn-out end 2b of the raw web 6b during standby. At the same time, the adhesive member 47 straddles the release paper 5 of the drawing end 2b of the raw material 6b in standby and the release paper 5 of the cut end 2a of the raw material 6a during transfer. Ryohin 6a, 6b
Release papers 5 and 5 are connected. That is, the cut end 2a of the material web 6a being transported is connected by the sticking member 47 and the adhesive tape main body 3 of the drawn-out end portion 2b of the material web 6b in standby, and the material web 6a is cut from the material web 6a. Continuous transfer to the counter 6b becomes possible.

Thereafter, in the standby means 50, the blower 5
The suction of both suctions 52a, 52b is released by the solenoid valve provided in the hose 54 of the third hose 54, the adhesive tape main body 3 of the drawn end 2b of the raw material 6b is detached from the lower suction 52b, and the upper suction 42a Then, the release paper 5 and the sticking member 57 are separated.

Next, while the suctions 52a and 52b are separated from each other by the air chuck 51, the dancer roll 15 is lowered again from the position indicated by the dashed line to the position indicated by the solid line, and the pressure-sensitive adhesive tape 2 is lengthened and is on standby. Material 6b
Is resumed.

The ends 2a, 2b of the webs 6a, 6b
However, since the adhesive tape main bodies 3 and 3 are connected to each other by being superimposed and the release papers 5 and 5 are connected by the attaching member 57, as shown in FIG. The release paper 5 can be continuously peeled from the anti-adhesive tapes 2 and 2 of 6a and 6b. And these two webs 6a, 6
After the release paper 5 is continuously peeled off, the connection between the ends 2a and 2b of FIG. b is cut and discharged to the outside.

Next, from the lower web 6b to the upper web 6a
In the state where the transfer has been started, the suctions 52a and 52b of the standby means 50 are located above and below the raw webs 6a and 6b. To this end, both suctions 52a. 52b is retracted from the web 6a, and the vertical cylinder 43 is moved.
As a result, both suctions 52a and 52b are moved downward to the lower standby line C.

Thereafter, after the transfer of the upper web 6a is started and before the remaining amount is detected by the optical sensor 16, the operator transfers the lower web 6b to be transferred next. While being set on the roll 11b, the adhering member 57 is attracted to the opposing surface of the suction 52a on the upper side of the standby means 50, and the release paper 5 at the drawn-out end 2b of the raw material 6b is peeled off from the adhesive tape main body 3 for adhering. The adhesive tape main body 3 is attached to the member 57, and the adhesive tape main body 3 is adsorbed to the lower suction 52b to be in a standby state.

When the remaining amount of the upper web 6a is detected by the optical sensor 16, the moving web 6b is cut by the moving feed roll 25 in the same manner as described above. At the same time, both suctions 5 located on the lower standby line C
2a and 52b are moved to the transfer line A by the horizontal and vertical cylinders 41 and 43, and the cut end 2b of the material web 6b being transferred is sent out between the adhesive tape main body 3 and the release paper 5 of the material web 6a in standby. Then, both suctions 52a and 52b are pressed against each other to connect the ends 2a and 2b of the two webs 6a and 6b.

As described above, one of the webs is transferred, and the other web is made to stand by. When the remaining web becomes small, the transfer of the web is interrupted and the web is transferred. Cut,
Since the adhesive tape main body at the cut end of the raw web and the adhesive tape main body at the drawn-out end of the raw web are connected, and the release papers of both raw webs are connected by an adhesive member, Continuous automatic transfer of the raw material can be realized.

In the case of the above-described embodiment, two original sheets 6 are used.
Although a and 6b are provided, more may be provided.

In the above embodiment, the cut end 2a of the material 6a being transferred is moved back to the transfer line A. However, the cutting means 20 and the forming means 33 are retracted from the transfer line A, and You may make it move to the position which can pull out | draw out the end part 2b of the raw material 6b inside. In short, in the transfer line A, the ends 2 of the two webs 6a, 6b
It is sufficient that a and 2b can be connected.

Further, in the above-described embodiment, the sticking member 57 having a rectangular shape in a plan view is used, but may be elliptical or circular, and the shape is not particularly limited. In short, the sticking member 57 includes the release paper 5 of the standby material 6b,
During the transfer, the two webs 6 are stretched over the cut end 2a of the web 6a.
Any shape may be used as long as the end portions 2a and 2b of the a and 6b can be connected. The sticking member 57 is attached to the release paper 5 in advance, but may be attached to the opposing surface of the suction 52 in advance.

Also, the withdrawal end 2b of the standby material 6b
