JP 2007-269402 A

  By the way, in the tack labeler 80 described above, in order to move the cup-shaped container B along the outer peripheral surface of the suction drum 83 while rotating, the container holder 89 of each container holding head 85 mounted on the container transport unit 84 is horizontally placed. For this purpose, the container holder 89 needs to protrude outward from the intermediate shaft 86 disposed on the concentric circle, so that the entire container transport unit 84 and, by extension, the tack labeler 80 are required. There is a problem that the whole is enlarged.

  Further, in order to increase the speed of the tack labeler, if the number of container holding heads 85 mounted on the container transport unit 84 is to be increased, it is necessary to ensure a certain distance between the adjacent container holders 89. The radius of the circular orbit in which the cup-shaped container B held by the container holder 89 moves is increased, and the moving speed of the cup-shaped container B is increased. Therefore, the peripheral speed of the suction drum 83 that conveys the tack label TL must also be increased in accordance with the moving speed of the cup-shaped container B. Accordingly, the peeling speed of the tack label TL from the release paper SP is also increased. Must be fast.

  Thus, if the peripheral speed of the suction drum 83 is increased, the supply speed of the tack label TL must be increased, and the peeling speed of the tack label TL from the release paper SP is necessarily increased. However, in order to reliably peel the thin tack label TL with no waist from the release paper SP, it is necessary to peel it off as slowly as possible. Therefore, the tack labeler for thin tack labels should be operated at high speed. The reality is that it is difficult.

  Accordingly, an object of the present invention is to provide a tack labeler that is compact and capable of high-speed operation.

In order to solve the above-mentioned problem, the invention according to claim 1 is directed to sequentially peeling the tack labels from the release paper while feeding the label supply strip in which a plurality of tack labels are attached to the long strip release paper. and the tack labeler having the label supply device, and a label sticking device for sticking the pasting target body receiving the tack labels supplied by the label supply device, the label sticking apparatus, adhesive While conveying the adherend along the suction drum that conveys the label to the label attaching position with the label adsorbed to the outer peripheral surface so that the surface faces outward, and the arcuate conveyance path passing through the label attaching position , and a rotary conveyance unit for rotating the pasting target body, Aspirate drum forms the suction surface of the tack label is divided in the circumferential direction, swing radially freely supported multiple circles Arc-shaped unit board A suction means connected to each of the units plate, and a plurality of swing mechanism for swinging independently of each units plate radially in the label sticking position, adsorbed units plate after contacting the Hiha adherend on the adhesive surface of the tack label is, that along the outer peripheral surface of the bonded adherend, while swinging the units plate by a rocking mechanism, pasting target body The tack label is attached to the adherend by rotating the stick, the moving speed of the adherend is set to be lower than the peripheral speed of the suction drum, and the stick label is attached from the start of sticking. The present invention provides a tack labeler in which the contact position of the adherend to the unit plate is gradually moved to the rear side in the moving direction of the unit plate until completion .

As described above, in the tack labeler according to the first aspect of the present invention, the suction drum constituting the label sticking device is divided in the circumferential direction, which forms the suction surface of the tack label, and can swing in the radial direction. A plurality of arc-shaped unit plates supported by the unit, suction means connected to each unit plate, and a plurality of swing mechanisms for individually swinging each unit plate in the radial direction. in the throw-on position, after contacting the Hiha adherend to the adhesive surface of the adsorbed tack labels to the unit plate, along the outer peripheral surface of the object to be bonded adherend, so as to swing the unit plate by rocking mechanism Therefore, it is not necessary to swing the adherend in the horizontal direction in order to move the adherend along the outer peripheral surface of the suction drum, unlike the conventional tack labeler for thin labels. , Along the circular path of the adherend Since it is only necessary to movement, without the transport unit is increased in size, the entire tack labeler becomes compact.
Further, in this tack labeler, the moving speed of the adherend is set to be smaller than the peripheral speed of the suction drum, and the contact position of the adherend to the unit plate between the start of the tack label sticking and the sticking completion. Will move gradually toward the rear side in the direction of movement of the unit plate, so even if the suction position of the tack label with respect to the unit plate has shifted to the rear side in the direction of movement of the unit plate for some reason, Can be attached to the body.

  In addition, when the tack labeler is operated at a high speed, the radius of the circular orbit along which the adherend moves is smaller and the moving speed of the adherend increases much compared to the conventional tack labeler for thin labels. There is nothing to do. Therefore, it is not necessary to increase the peripheral speed of the suction drum that transports the tack label, and the tack label can be peeled off from the release paper slowly and reliably, so that the tack labeler for thin-walled tack labels can be operated at high speed. It becomes possible to plan.

The main body base 71 is provided with a synthetic resin support block 71b that supports one side of the movable base 76, and the movable base 76 slides on the support block 71b.

  The labeling operation of the tack labeler 1 configured as described above will be described below. First, the label supply belt LB is fed out from the label supply roll LR set in the label supply devices 3 and 3 and is sent to the label supply positions α1 and α2. At the label supply positions α1 and α2, the peeling plate 13 is supplied. By pulling the release paper SP that is hooked to the release paper abruptly in the opposite direction, the tack label TL is peeled from the release paper SP, and the start end of the release paper SP faces the suction drum 21 with the adhesive surface facing outward. After being positioned by being sucked and held in the suction hole 31a formed on the outer surface of the unit plate 28, the entire tack label TL is adsorbed to the outer surface of the unit plate 28 by this suction force and electrostatic suction force. In this state, it is conveyed to the label attaching positions β1 and β2.

  In this way, in the state where the tack label TL is transported to the label attaching positions β1 and β2, as shown in FIG. 11A, the cup-like container B is also attached to the label attaching positions β1 and β2 by the container transport unit 45. The outer peripheral surface of the body portion of the cup-shaped container B is pressed against the adhesive surface of the tack label TL adsorbed to the outer surface of the unit plate 28 of the suction drum 21, and the end portion of the tack label TL is the cup. Attached to the outer peripheral surface of the body of the cylindrical container B Subsequently, as shown in FIGS. 2B and 2C, the drum body is rotated while the unit plate 28 swings along the outer peripheral surface of the cup-shaped container B which is rotating on the circular orbit while rotating. Since 22 rotates, by this, the whole tack label TL is stuck to the trunk | drum outer peripheral surface of the cup-shaped container B. FIG.

  The contact position of the cup-like container B with respect to the unit plate 28 is set so as to gradually move forward in the moving direction of the unit plate 28 between the start of sticking of the tack label TL and the completion of sticking. If the relative position between the cup-shaped container B and the unit plate 28 is set so as not to change from the start of sticking of the label TL to the completion of the sticking, the suction position of the tack label TL with respect to the unit plate 28 is caused by some reason. When the unit plate 28 is displaced backward in the moving direction, the outer peripheral surface of the body portion of the cup-shaped container B cannot be brought into contact with the tack label TL at the start of sticking of the tack label TL. Since there is a possibility that it cannot be attached to the outer peripheral surface of the body portion of the cup-shaped container B, in this tack labeler 1, from the start of sticking of the tack label TL to the completion of sticking. In the meantime, the moving speed of the cup-shaped container B is slightly higher than the peripheral speed of the drum body 22 so that the contact position of the cup-shaped container B with the unit plate 28 gradually moves backward in the moving direction of the unit plate 28. It is set to be smaller.

  In addition, the inclination angle of the outer peripheral surface of the body of the cup-shaped container B and the inclination angle of the outer peripheral surface of the drum main body 22 cannot always be completely matched from the start of the attachment of the tack label TL to the completion of the attachment. Therefore, in this tack labeler 1, as shown in FIG. 11B, when the tack label TL is pasted only half of the entire length, the outer peripheral surface of the body portion of the cup-shaped container B constitutes the drum body 22. In the state where the cushion material 30 of the unit plate 28 is depressed by a predetermined amount, the inclination angle of the outer peripheral surface of the body portion of the cup-shaped container B and the inclination angle of the drum body 22 are set to coincide with each other. Tack label from the time when TL sticking is started (see FIG. 11 (a)) to immediately before the tack label TL is pasted by half of the entire length and immediately after the tack label TL is pasted by half the full length. Until the time when TL sticking is completed (see FIG. 11C), the outer peripheral surface of the body of the cup-shaped container B is the cushion material 30 of the unit plate 28 on the large-diameter portion side of the cup-shaped container B. Is partially recessed so that the outer peripheral surface of the body of the cup-shaped container B is brought into contact with the outer surface of the unit plate 28. That is, at the start of sticking the tack label TL, as shown in FIG. 12 (a), in the small diameter portion of the cup-shaped container B, the outer peripheral surface of the body of the cup-shaped container B hardly dents the cushion material 30. In the large diameter portion of the cup-shaped container B, the body outer peripheral surface of the cup-shaped container B is in a state where the cushion material 30 is depressed by a predetermined amount. Then, as the sticking of the tack label TL proceeds, the amount of depression of the cushion material 30 on the small diameter portion side of the cup-shaped container B gradually increases, and at the time when the tack label TL is pasted only half of the entire length. As shown in FIG. 5B, the outer peripheral surface of the body portion of the cup-shaped container B is in a state where the cushion material 30 is depressed by a predetermined amount from the small-diameter portion of the cup-shaped container B to the large-diameter portion. . Subsequently, when the adhesion of the tack label TL further proceeds, conversely, the amount of depression of the cushion material 30 on the small diameter side of the cup-shaped container B gradually decreases, and at the point when the adhesion of the tack label TL is completed, As shown in FIG. 5A, the state is the same as when the tack label TL starts to be attached.

  As described above, the tack labeler 1 divides the drum body 22 constituting the suction drum 21 into a plurality of arc-shaped unit plates 28 that form the suction surface of the tack label TL, and the label attaching position β1. , Β2, the cup-shaped container B is brought into contact with the adhesive surface of the tack label TL adsorbed to the unit plate 28, and then the unit plate 28 is swung along the outer peripheral surface of the cup-shaped container B. Therefore, to move the adherend such as a cup-shaped container along the outer peripheral surface of the suction drum like the conventional tack labeler for thin labels, the adherend is swung horizontally. Since the cup-shaped container B only needs to be moved along the circular orbit, the container transport unit 45 is not increased in size and the entire tack labeler becomes compact.

  Further, in order to increase the speed of the tack labeler 1, the cup-shaped container B moves as compared with the conventional tack labeler corresponding to the thin label, even when the number of the container holding heads 54 mounted on the container transport unit 45 is increased. The radius of the circular orbit is reduced, and the moving speed of the cup-shaped container B does not increase so much. Therefore, it is not necessary to increase the peripheral speed of the suction drum 21 that conveys the tack label TL, and the tack label TL can be slowly and surely peeled off from the release paper SP. It is possible to increase the operation speed of the tack labeler.

  In the above-described embodiment, as shown in FIG. 11, the contact position of the cup-shaped container B with respect to the unit plate 28 is the rear of the unit plate 28 in the moving direction between the start of sticking of the tack label TL and the completion of sticking. However, the present invention is not limited to this, and the relative position between the cup-shaped container B and the drum body 22 is not limited to this, from the start of sticking of the tack label TL to the completion of sticking. It is also possible to set the moving speed of the cup-shaped container B and the peripheral speed of the drum main body 22 to the same speed so as not to change.

  Further, in the above-described embodiment, in order to attach two tack labels TL such as a front label and a back label to the outer peripheral surface of the body of the cup-shaped container B, two label supply devices 3 and 3 are mounted. However, the present invention is not limited to this, and when a single tack label is to be pasted, only one label supply device 3 may be mounted. When three or more tack labels are to be pasted, Three or more label supply devices 3 may be mounted.

  Further, in the above-described embodiment, when the tack label TL is attracted to the outer surface of the unit plate 28 in the suction drum 21, the static electricity on the surface of the unit plate 28 is used. However, the present invention is not limited to this. It is also possible to suck and hold the tack label on the outer surface of the unit plate without using. In this case, the suction holes other than the vicinity of the sticking start end of the tack label may be weak suction by fine holes so that the tack label can slide (slide or shift) on the drum surface.

  Moreover, although embodiment mentioned above demonstrated the tack labeler 1 which affixes the tack label TL to the outer peripheral surface of the trunk | drum of the cup-shaped container B, it is not limited to this, Various forms of taper shape and straight shape are covered. It goes without saying that the tack labeler of the present invention can also be used when a tack label having an arbitrary shape is stuck on the sticking body.

  Further, in the above-described embodiment, the case where the thin tack label TL with no waist is attached to the outer peripheral surface of the body portion of the cup-shaped container B is described, but the present invention is not limited to this, and the tack labeler of the present invention is not limited thereto. Needless to say, the present invention can also be applied to a case where a thick, thick tack label with a waist is attached to the outer peripheral surface of the body part of the adherend having a body part tapered.

  It can be applied to a case where a tack label is adhered to an adherend such as a container at high speed and cleanly.
