Description

  The present invention relates to a label transfer device and a label sticking device, and more specifically, a label transfer device for transferring and sticking a label issued from a label issuing unit to a moving article (article) to be moved, and a label sticker provided with the label transfer device Relates to the device.

  The label issued by the label issuing unit is attached to a belt that rotates endlessly, transferred to the opening of a conveyor that conveys the object to be adhered (article), and labeled on the bottom surface of the object to be adhered that is moved by driving the conveyor. In order to peel off the label attached to the belt, an independent peeling roller is provided in the vicinity of the opening of the conveyor and in the vicinity of the downstream side of the belt for transferring the label. A technique for peeling from a belt has been proposed (see, for example, Patent Document 1).

  However, in the proposed system, the peeling roller is disposed independently in the vicinity of the rotating body (the pulley is fixed to the shaft) on the downstream side around which the belt to which the label is attached and wound is wound. When the belt is a weak label, when the belt is folded back by the rotating body on the downstream side, the leading end of the label is peeled off from the belt surface and is not pushed out linearly, but is fed out in a state of falling to the belt side. . Therefore, when the leading end of the label hits the peeling roller, the label is not peeled off from the belt, but is wound and transferred to the return path side (opposite side) as the belt rotates, and the label is not attached to the bottom surface of the article. There is a possibility that a sticking failure (error) may occur.

JP 2002-321721 A

  The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to attach a label issued from a label issuing unit to a rotating belt that rotates endlessly up to an object to be pasted. In the transporting label transport device, even if the label attached to the endless rotating belt is weak, the label can be reliably peeled on the downstream side of the rotating belt and can be reliably attached to the object to be pasted. An apparatus and a labeling apparatus are provided.

In order to achieve the above object, a label transfer device according to the present invention is a label transfer device that attaches a label issued from a label issuing unit to a rotating belt that rotates endlessly and transfers the label to a predetermined position. And a position near the predetermined position at a position downstream of the position and in the vicinity of the predetermined position on the downstream side of the label transfer direction, and coaxial with the axis near the predetermined position and outside the surface of the rotation band. projecting, characterized a configuration in which a label peeling unit for irregularities on the outer peripheral surface at the disc is provided (claim 1).
The rotation band is not limited to a rubber or resin belt, but may be a metal chain or the like. In addition, the belt width (belt width) of the rotating belt may be either wide or narrow. However, in consideration of label adhesion and peelability, a plurality of narrow rotating belts are arranged at predetermined intervals in the width direction. Is preferred.
In addition, the irregularities are formed in parallel at regular intervals along the circumferential direction (e.g., gear form), irregularly formed along the circumferential direction (irregular), or intersecting groove forms. Either may be used.

The label peeling portion is configured to rotate integrally with a shaft that supports the downstream side of the rotation band, and is integrally formed with the shaft, or is fixed so as to integrally rotate the shaft and the label peeling portion of a separate structure. Any of them may be used. And this label peeling part is arrange | positioned so that it may be located in the width | variety of the label attached to a rotation belt.
Further, the label peeling portion protrudes outward from the surface of the rotating band, but the protruding amount is that the label attached to the rotating band is pushed up from the surface of the rotating band by the turning rotation of the rotating band and peeled off. For example, it is projected from the surface of the rotating belt by about 0.5 mm to 1.0 mm.

According to the above means, the label issued from the label issuing unit and attached to the rotation band of the label transfer device is transferred downstream by the rotation of the rotation band. Then, the rotating band to which the label is attached is folded back on the return path side by an axis provided in the vicinity of a predetermined position on the downstream side, and a label peeling portion that protrudes outward from the surface of the rotating band is provided on the axis. For this reason, the labels attached as the rotating band is folded are sequentially peeled from the leading end side in the transport direction. Therefore, the label is not caught and transferred to the return path side while adhering to the rotation band.
Moreover, since the label peeling part protrudes outside from the surface of a rotation belt | band | zone, the peripheral speed of a label peeling part becomes quicker than the transfer speed (speed of a rotation belt | band | zone) of a label. Therefore, when the label is peeled off from the rotating belt and sent out, the label peeling portion acts to slip against the label, and the glue attached to the label peeling portion acts on the label's adhesive surface, thereby the label peeling portion. It becomes difficult to attach the label paste to the side.

Further , according to the above means, since the outer peripheral surface of the label peeling portion is uneven, the area in contact with the label is smaller than that of the label peeling portion having a flat outer peripheral surface. Thereby, the glue of the label becomes difficult to adhere to the label peeling portion.

Also, the label peeling unit may be a guide portion for regulating the winding position of the rotating band on said axis (claim 2). That is, the label peeling portion is arranged on both sides in the width direction or on one side so as to sandwich the rotation band wound around the shaft.

  According to the above means, since the winding position of the rotation band is regulated by the label peeling portion, it is possible to prevent the rotation band from moving (meandering) on the axis in the axial direction. That is, in addition to the stable rotation of the rotating band and the stable transport of the label, it is possible to have both effects that the label peeling by the label peeling portion is also reliably performed.

The label transfer device can apply the label to the upper surface or the side surface of the adherend by changing the arrangement of the adherend with respect to the conveyance path. However, the most preferred use is disposed below the conveying means for conveying a sticking material, and a label transfer device for Shitabari label sticking the label on the bottom of the attached material moved by the transport means (claim 3 ).

  According to the above means, even in a label sticking device for sticking a label to the bottom surface of the object to be pasted, the label can be reliably peeled off from the rotating band of the label transfer device and reliably stuck to the bottom surface of the object to be pasted.

According to the label transfer device of the present invention, the label attached as the rotating belt is folded is sequentially peeled from the leading end side in the transfer direction. Therefore, the label is not caught and transferred to the return path side while adhering to the rotation band. When the label is peeled off from the rotating belt and sent out, the label peeling part works to slip against the label, and the glue attached to the label peeling part acts on the adhesive surface of the label, thereby removing the label. It is difficult for the label glue to stick to the part side, and the label peeling part protrudes outward from the surface of the rotating belt, and the outer peripheral surface is provided with irregularities on the outer surface of the disc, so that the label glue is further removed from the label peeling part. Therefore, the label can be peeled off reliably.
According to the second aspect of the present invention, the rotation of the rotating belt is stable and the label is also stably transported. Therefore, the label is peeled off by the label peeling portion with certainty.
Further, in the label affixing device for affixing the label to the bottom surface of the object to be pasted by the configuration according to claim 3 , the label is surely peeled off from the rotation band of the label transfer device and the affixed to the bottom surface of the affixed object be able to.

Hereinafter, an example of an embodiment of a label transfer device according to the present invention will be described with reference to the drawings.
FIG. 1 is an external view in which a label transfer device according to the present invention is incorporated and arranged in a label underlaying device. In the figure, A is a label transfer device, and includes a label issuing unit B and a transport means C for transporting an adherend W. The label 9 disposed between and issued from the label issuing unit B is configured to be transferred to the object to be adhered W moved by the conveying means C and adhered to the bottom surface of the object to be adhered W.
Since the label issuing unit B has a well-known structure today, a detailed description thereof will be omitted. In the drawing, the mount 9 ′ temporarily attached with the label 9 is bent by the dispenser 10 and temporarily attached to the mount 9 ′. Only the portion where the label 9 is peeled off is shown. The label issuing unit B is not limited to a label printer having a printing function, and a label on which a predetermined item is printed in advance may be temporarily attached to a mount, and the printed label may be released from the mount. Further, the label is not necessarily limited to the type temporarily attached to the mount, and a so-called mountless label without a mount may be issued from the label issuing unit.

  In the label transfer device A, a pair of rotating shafts 2 and 2 'winding and holding a rotating band 3 for attaching and transferring the label 9 between the side plates 1 and 1' facing each other at a predetermined interval are spaced apart from each other. The rotary shaft 2 that is installed and supported in the vicinity of the label issuing unit B is configured to be driven and rotated by a motor 4 and a power transmission means 5.

The rotating shafts 2 and 2 ′ receive the label 9 issued from the label issuing unit B, attach the received label 9 to the surface of the rotating belt 3, and to the article W to be moved by the conveying means C. It arrange | positions providing the space | interval which can be transferred.
The rotating shaft 2 driven and rotated by the motor 4 and the power transmission means 5 is provided with irregularities (serrations) 6 on the outer peripheral surface so as not to cause slip or the like between the rotating belt 3 and the rotating belt 3. It is comprised so that it can drive reliably. The rotating shaft 2 ′ arranged in the vicinity of the conveying means C may be formed with unevenness (serration) on the outer peripheral surface as in the rotating shaft 2, or may be a smooth surface without forming the unevenness.

The rotating band 3 wound around the rotating shafts 2 and 2 'is formed of a narrow toothed belt formed of rubber or resin or the like, and there are a large number of toothed belts and the rotating shafts 2 and 2'. The teeth 3a formed on the inner side of the belt engage with the irregularities (serrations) 6 of the rotating shaft 2 and are reliably rotated. ing.
The toothed belt of the rotating belt 3 may be a double-sided toothed belt having a tooth portion 3a ′ formed on the outside of the belt. In this case, the contact area with the label attached to the surface of the rotating belt 3 As a result, the operation of peeling the label from the rotation band 3 can be performed smoothly.

  A rotating body 7 is fitted on the rotary shaft 2 so as to be free-wheeling so as to be positioned between the rotary bands 3 arranged side by side and project outward from the outer surface of the rotary band 3. The rotating body 7 allows the leading end of the label issued from the label issuing unit B to first adhere to the rotating body 7, whereby the label is attached and transferred at the speed of the label issued from the label issuing unit B. This eliminates the pulling of the label that occurs due to the high transfer speed of the rotating belt 3, and can prevent the printing issue in the label issuing section B.

On the other hand, a label peeling portion 8 that protrudes outward from the surface of the rotating band 3 is integrally formed on the same axis as the rotating shaft 2 ′.
As shown in FIG. 3, the label peeling portion 8 is formed on a circular plate 8a, and the outer peripheral surface thereof is formed with irregularities 8b in a gear shape along the circumferential direction. The difference (H) between the outer surface of the label peeling portion 8 and the outer surface of the rotating band 3 is that the label attached to the surface of the rotating band 3 is rotated on the surface of the rotating band 3 at the rotating shaft 2 'serving as the end of transfer. What is necessary is just to have a level difference that allows the label to be forcibly peeled off from the surface of the rotating band 3 by riding on the label peeling portion 8 that protrudes outward. The difference (H) is set, for example, such that the outer surface of the label peeling portion 8 is about 0.6 mm higher than the surface of the rotating band 3.
Further, the label peeling portion 8 may be a smooth surface without making the outer peripheral surface uneven, but as shown in the figure, the uneven contact surface can reduce the contact area with the label. Since the area to which the glue is attached is reduced, the label peeling portion 8 does not become an obstacle to the label transfer, and the sticking operation for sticking the peeled label to the article to be pasted can be performed smoothly.

  Further, the label peeling portion 8 is arranged and formed so as to sandwich each rotation band (toothed belt) 3 wound around the rotation shaft 2 '. As a result, the label peeling portion 8 can also serve as a guide portion for preventing a large number of rotation bands 3 arranged in parallel across the rotation shafts 2 and 2 ′ from moving (meandering) in the axial direction.

FIG. 4 shows another example of attachment of the rotary band 3 wound around the rotary shafts 2 and 2 ′, and FIG. 4 (a) shows that the rotary band 3 ′ is spaced so that both sides of the label in the width direction can be attached. Further, a plurality of label peeling portions 8 are arranged side by side between the two rotating bands 3 ′ on the rotating shaft 2 ′.
In FIG. 4 (b), one wide rotating band 3 "is attached so that the central portion except for both sides in the width direction of the label can be attached, and both sides of the rotating band 3" are attached to the rotating shaft 2 '. A plurality of label peeling portions 8 are arranged in parallel at the sandwiching positions (positions corresponding to both sides of the label). In addition, the same member as the member shown by previous embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.
In either case of FIGS. 4A and 4B, since the label peeling portion 8 arranged on the rotating shaft 2 ′ is located within the width of the label to be transferred, the rotating band 3 ′ and the rotating band 3 The label peeled off by the label peeling portion 8 is positioned on the rotary shaft 2 'when the label attached to "" is transferred to the rotary shaft 2'.

  As shown in FIG. 5 (a), when the label transfer device configured as described above is transferred to the rotating belt 3 (or 3 ′, 3 ″) in which the leading end side of the label 9 issued from the label issuing unit B rotates endlessly. In addition, the label 9 is transported with the entire length along the label transfer direction attached to the surface of the rotation band 3 as the rotation band 3 rotates, and the label 9 is terminated by the rotation of the rotation band 3. When it is transferred to the side, the label 9 is transferred as shown in FIG. 5 (b) because the end side rotary shaft 2 'is provided with a label peeling portion 8 that protrudes outward from the surface of the rotary band 3. Ride on the label peeling part 8 from the front end in the direction and peel off from the surface of the rotating band 3 in sequence, so even if the label is weak, the label remains attached to the rotating band as it is without peeling from the rotating band. It is not caught up, and is surely peeled off from the rotating belt and carried It can be affixed to the bottom surface of the attached material W through the opening 11 of the unit C.

In addition, since the outer peripheral surface of the label peeling portion protrudes from the surface of the rotation band, the peripheral speed of the label peeling portion is faster than the label transfer speed due to the rotation of the rotation band. Therefore, during the delivery of the label to the opening of the conveying means C, the label peeling portion 8 works to slip with respect to the label, and the glue attached to the label peeling portion 8 acts on the label adhesive surface, so that the label peels off. It becomes difficult for the glue of the label to stick to the part. And, when the label peeling part has a gear shape with irregularities formed on the outer peripheral surface, the area in contact with the label is reduced, so that the label glue is less likely to adhere to the label peeling part, and the label is smoothly fed out. It can be carried out. In the figure, reference numeral 12 denotes an air injection nozzle for directing the leading end side of the label 9 issued from the label issuing unit B to the label transfer device A.
In the figure, reference numeral 13 denotes a guide roller located on the downstream side in the vicinity of the label peeling portion 8 and arranged so as to be freely rotatable between the side plates 1 and 1 '. It functions to prevent the rear end side from bending and sticking to the workpiece W.

However, depending on the size of the label and the adhesive strength of the glue applied to the adhesive surface of the label to be used, It is good also as a structure which can change a mounting position and the protrusion amount (height H in the said embodiment) from the surface of a rotation belt | band | zone suitably.
(2) In the embodiment, the label pasting device in which the label transfer device is arranged on the lower side of the conveying means is shown. However, the present label transport device is not limited to the label pasting device, and the label is attached to the side of the object to be pasted. The present invention can be applied to any one of affixing to the side and affixing a label on the upper surface of an object to be pasted. Further, immediately after the rotating shaft 2 ′, an applicator that adsorbs the peeled label is put on standby, and the surface (upper surface, bottom surface, The label transfer device of the present invention may be used in a mechanism that is attached to the side surface. In addition, the object to be attached (article) to which the label is attached is attached to the object to be attached (article) to be transported as in the above embodiment, and is also placed by a worker at a predetermined place as described above.
