Abstract

PROBLEM TO BE SOLVED: To stick a tab without stopping a feed mechanism by changing a connection with a suction pad from a vacuum source to an air source, sucking the fed out tab for blowing and sticking it to an object by a press roller. SOLUTION: While an apparatus 20 is moved by a feed mechanism 32, a separator reel 31 is driven to pull a separator S, a tab T is peeled from the separator S by an edge guide 23, and it is fed between a suction pad 23 and an auxiliary suction guide 33. When the tab T reaches a predetermined position, the suction pad 23 connected to a vacuum source 24 sucks the tab T and also stops rotation of a separator reel 31. Then the suction pad 23 is moved by a travel mechanism 27 with the tab T sucked. The feed mechanism 32 is not stopped even if it reaches a predetermined tab sticking position, the suction pad 23 is connected to an air source 25 by a switch valve 26 for ejecting air, and the tab T is blown toward an object on a working table W to be stuck and pressed in a press roller 29 by a removal mechanism 30.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for peeling off a tab continuously attached to a separator and attaching the same to an object, and more particularly to an automatic winding paper tailoring apparatus in which a tab for preventing peeling is used. The present invention relates to a tab sticking device suitably used for sticking to a paper edge portion of a paper.

[0002]

2. Description of the Related Art Conventionally, a tab sticking device of this kind is shown in FIG.
The following are known. In the illustrated tab application device 10, the separator S to which the tab T is applied is attached to the tab reel 11.
And the separator S is inverted at the edge guide 12 so that the rigid tab T is separated from the separator S.
Separated from The tab T separated from the separator S in this manner is sent out between the suction pad 13 and the suction assisting guide 14, and is sucked by the suction pad 13. As shown in FIG. 2, the suction pad 13 has a large number of suction holes a for uniformly generating a vacuum on its suction surface, one of which is connected to the vacuum source 15, and the tab T completely closes the suction holes a. Only after that, the suction of the tab T is performed. The suction timing is confirmed by detecting the tip of the fed tab T with a sensor (not shown). Then, the suction pad 13 that has sucked the tab T is moved by the traveling mechanism 16 so as to avoid the suction assist guide 14, and is pressed against the work table W by the pressing mechanism 17 so that the tab T is attached to the target object on the work table W. wear. On the other hand, the separator S that has passed through the edge guide 12 is taken up on a separator reel 18 that is driven to rotate. This series of operations is performed each time one tab is pasted, and the feed mechanism 19 driven by the motor M moves to the next tab pasting position.

[0003]

In the above-described tab attaching apparatus, when the tab T is pressed against the work table W by the pressing mechanism 17, the feed mechanism 19 needs to be stopped.
As shown by an arrow P in the drawing, there is a problem that it takes a long working time when the tab T is used for tailoring a roll of paper to be stuck at many positions.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a tab sticking apparatus which can stick a tab without stopping a feeding mechanism.

[0005]

In order to achieve the above object, a tab attaching apparatus of the present invention comprises a tab reel for feeding out a separator to which a tab is attached, an edge guide for peeling off the tab from the separator and sending out the tab. A suction pad for sucking and blowing off the fed tab with a suction surface having a large number of suction holes, a switching valve for switching the connection of the suction pad to a vacuum source or an air source, and a direction perpendicular to the pushing direction of the suction pad. A traveling mechanism for traveling, an extruding mechanism for bringing the suction pad closer to the object to a predetermined position, a pressing roller for holding down the attached tab, a detaching mechanism for attaching and detaching the pressing roller to and from the object, and And a feed mechanism for moving the entire device in the direction perpendicular to the suction pad pushing direction. Characterized in that it comprises.

[0006]

Next, an embodiment of the present invention will be described. FIG. 3 is a plan view showing a tab sticking apparatus as one embodiment of the present invention.

The illustrated tab application device 20 is used by being incorporated into an automatic web tailoring device used in a rotary printing press. The tab application device 20 is provided with a tab reel 21 for feeding out a separator S having a tab T attached thereto, and the tab T is separated from the separator S. Guide 22 for sucking and blowing out the fed tab T, a switching valve 26 for switching the connection of the suction pad 23 to a vacuum source 24 or an air source 25, and a suction pad 23. , A pushing mechanism 29 that pushes the suction pad 23 close to the target object to a predetermined position, a pressing roller 29 that presses the attached tab T, and a pressing roller 29 that moves the suction roller 23 to the target object. A detachable mechanism 30 for attaching and detaching the tab S, a separator reel 31 for winding up the separator S after the tab T is detached, and the entire apparatus And a feed mechanism 32 for moving in a direction perpendicular to the suction pads extrusion direction. As the feed mechanism 32, a linear motion mechanism combining a ball screw and a motor may be used as shown in the figure. In addition, suction pad 2
The traveling mechanism 27 of 3 may use an air cylinder,
An air cylinder may be used for the pressing mechanism 28 and the attaching / detaching mechanism 30. The suction pad 23 is the same as described above, and has a large number of suction holes on the suction surface, and these suction holes are connected to the vacuum source 24 and the air source 25 as a single unit.

In the tab attaching apparatus 20, the feed mechanism 32
By moving the separator reel 31 with a motor and pulling the separator S while moving the entire apparatus to the tab application position, the tabs T are separated from the separator S at the edge guides 22 while the suction pad 23 and the suction auxiliary guide 33 are separated. Send in between. Tab T is suction pad 23
When a predetermined position is reached at which all the suction holes are closed, the suction pad 23 connected to the vacuum source 24 sucks the tab T by the switching valve 26, and stops the rotation of the separator reel 31 to stop the feeding of the tab T. Then, the suction pad 23 travels in the lateral direction by the traveling mechanism 27 while holding the tab T by suction and stands by. When the feed mechanism 32 reaches the predetermined tab sticking position, without stopping, the suction pad 23 is connected to the air source 25 by the switching valve 26 to inject air,
The tab T is blown off and adhered to the object on the work table W, and the attachment / detachment mechanism 30 firmly presses the tab T against the object with the pressing roller 29 in contact with the object. In this way, the tabs T are sequentially attached without stopping the feed mechanism 32.

The tab sticking apparatus according to the present invention can be used not only for splicing in an automatic paper roll tailoring apparatus but also for sticking a general seal.

[0010]

As described above, the tab sticking device of the present invention is provided with a mechanism for back-injecting air to the suction pad, so that the tab is blown off by air and stuck to the object without being pressed against the work table. Can be. For this reason, tabs can be pasted one after another without stopping the feed mechanism of the apparatus, and the working time can be reduced. In addition, by blowing air, paper dust, dust, and the like attached to the suction surface of the suction pad can be removed, and a reduction in the tab suction force of the suction pad can be prevented.
