Description

  The present invention relates to a label sticking apparatus for automatically sticking a label to an article, and more particularly, to a label sticking apparatus for sticking a label that is peeled off from a belt-like mount and sent by a holding plate.

Conventionally, as this kind of label sticking device, for example, one disclosed in JP-A-6-278729 (Patent Document 1) is known.
As shown in FIG. 5, the article W is conveyed by a conveyor (not shown), and a label L is attached to the article W in this conveying process. A plurality of labels L are temporarily attached at regular intervals. The board D is transferred from the supply reel 100 to the take-up reel 101. In this transfer process, the label L is printed by the printing mechanism 102, and then the belt-like board D is folded by the peeling plate 104 in the label peeling unit 103. The label L is peeled off from the belt-like mount D and sent out. The delivered label L is held by a holding plate 105 provided near the downstream side of the peeling plate 104. The holding plate 105 has a contact surface 105a that comes into contact with the surface of the label L to be delivered and sucks by sucking air, and holds the label L by holding the label L by bringing the surface of the label L into contact with the contact surface 105a. The back surface of the label L is moved to two positions of the attaching position Y where the label L is attached to the article W. A large number of suction ports (not shown) for sucking air are formed on the contact surface 105a of the holding plate 105, and suction is performed in synchronization with the peeling of the label L, and the label L is peeled off. Then, the contact surface 105a is slidably brought into contact with the holding plate 105 while being sucked from its tip, and the entire surface of the label L comes into contact with the contact surface 105a after being peeled off. In this case, the reason why the label L can move on the contact surface 105a while being attracted to the holding plate 105 is that the label L can maintain a flat posture due to the rigidity of the label itself. Thereafter, the holding plate 105 is moved and pressed toward the article W, whereby the label L is affixed to the article W.

By the way, in recent years, with diversification of labels, labels with weak rigidity, for example, very thin labels, or elongate labels having a length exceeding 200 mm, for example, are used. However, there is a problem that such a weakly rigid label is liable to cause an adsorption failure and may be unsuitable.
This is because the label L can be moved on the contact surface 105a while being attracted to the holding plate 105 because the label L can maintain a planar posture due to the rigidity of the label itself as described above. As shown in the figure, when the rigidity becomes weak like an elongated label L, the so-called “waist” becomes weak. (A1 in FIG. 6), the label L is not sent to the holding plate 105 until the end (A2 in FIG. 6), or the label L is sent obliquely to the holding plate 105 (A3 in FIG. 5). ) And the like are likely to cause poor adsorption.

  In order to solve this problem, there has been a technique previously proposed by the applicant of the present application and published in Japanese Patent Application Laid-Open No. 2007-261678 (Patent Document 2). This label sticking device captures the leading edge of the label sent to the holding plate with a capturing body, moves the capturing body in the label feeding direction, pulls the label, and moves the label over the entire contact surface of the holding plate. It is gradually moved so as to be sucked and held on the contact surface of the holding plate.

JP-A-6-278729 JP 2007-261678 A

  However, in this type of label affixing device that pulls the conventional label, since the leading end of the label is captured by the capturing body and pulled, if the label has weak rigidity, it may be bent inward during delivery or the holding plate In contrast, the situation where the label is not sent to the end or the label is sent obliquely to the holding plate is prevented, and the holding failure is solved, but it is captured by the catching body and pulled. The supplementary mechanism and the traction mechanism have a drawback that the mechanism is complicated and expensive. Further, since the label is pulled and adsorbed, it cannot be handled unless the label is elongated to some extent, and there is a disadvantage that it is difficult to cope with a relatively short label.

  The present invention has been made in view of the above-described problems. Even if the label is very thin, such as a very thin label or an elongated label, the label can be securely held on the holding plate, and the label can be made relatively short. It is an object of the present invention to provide a label applicator that can cope with the above-mentioned problem and that can be realized with a mechanism as simple as possible.

In order to solve the above-described problems, the label sticking device of the present invention has a contact surface that comes into contact with the surface of the label that is peeled off from the belt-like mount and is sent out, and the label surface is brought into contact with the contact surface. In a label sticking apparatus provided with a holding plate that is moved to two positions of a holding position to hold and a sticking position to stick the back side of the held label to an article,
At the holding position of the holding plate, the guide position where the back surface of the label sent out against the contact surface is supported and guided, and the surface of the label comes into contact with the contact surface, and immediately before the holding plate reaches the sticking position. The guide member is configured to include a guide member that is retracted from the back surface of the label and is movable to two retracted positions that allow the label to be attached by the holding plate, and a moving mechanism that moves the guide member.

Thus, when affixing a label to an article, the label temporarily attached to the belt-like mount is peeled off at the holding position of the holding plate, and when the label is sent out toward the holding plate, the label is positioned at the guide position. The back surface of the guide member is guided while being supported, and the guide member is gradually moved and brought into contact with the entire contact surface of the holding plate. In this case, since the label is guided while being supported by the guide member, even if the label has low rigidity, it may be bent inward during delivery, the label may not be delivered to the end of the holding plate, or Such a situation that the label is obliquely delivered to the holding plate is prevented, and the holding plate is securely held. Further, since the guide member faces the contact surface of the holding plate, it can cope with a relatively short label.
Thereafter, the holding plate is moved from the holding position to the sticking position. In this case, the guide member is positioned from the guide position to the retracted position immediately before the holding plate reaches the application position, and is retracted from the back surface of the label. Therefore, since there is no guide member between the contact surface of the holding plate and the article, the contact surface of the holding plate presses the back surface of the label against the article, thereby the label held on the holding plate. Is affixed to the article.

  In this way, the label is guided and supported by the holding plate while being supported by the guide member, so that the holding plate does not have to have an adsorption function as in the conventional case, and the mechanism is simplified accordingly. Can do. Further, since the guide member may have a structure for supporting the label, the structure can be simplified, and the mechanism can be simplified accordingly. Furthermore, since the moving mechanism only needs to move the guide member to the two positions of the guide position and the retracted position, the structure can be simply configured. In this respect, the mechanism can be simplified and the structure can be made relatively inexpensively. Can do. Note that the holding plate may have a suction function. In this case, adjustment is made as appropriate, such as setting the suction force to a weak one, but the suction is held and the label is held. be able to.

  And as needed, it is set as the structure which each provided the said guide member in the sending direction right and left of the label of the said holding plate. Since the label is supported from the left and right in the delivery direction, the support is stable and the label can be securely held.

If necessary, the guide member is configured to be rotatable about an axis perpendicular to the label feeding direction , and the back surface of the fed label is constituted by a rollable roller. Since the roller rolls and supports the back side of the label, the label can be fed smoothly.

  Further, if necessary, the holding plate is provided with an arm that includes a contact member that can contact the article at the tip and supports the guide member via a support rod in the middle of the longitudinal direction. The guide member is positioned at the guide position by the weight of the arm when the arm is located at the affixing position, and when the holding plate reaches the affixing position, the abutting member abuts against an article and the holding plate moves as described above. The base end side of the arm is rotatably provided on the holding plate so that the guide member is located at the retracted position. By simply rotating the arm with a simple mechanism, the guide member can be moved to the two positions of the guide position and the retracted position, and the mechanism can be easily created accordingly.

  According to the present invention, at the holding position of the holding plate, the label is guided while the back surface is supported by the guide member positioned at the guide position, and is gradually moved and brought into contact with the entire contact surface of the holding plate. Therefore, even if the label is weak, it may be bent inward during delivery, the label may not be delivered to the end of the holding plate, or the label may be sent obliquely to the holding plate. Is prevented and can be securely held on the holding plate. Further, since the guide member faces the contact surface of the holding plate, it can cope with a relatively short label.

  In addition, since the label is guided and held by the holding plate while being supported by the guide member, it can be held without having the suction function of the holding plate. Can be simplified. Further, since the guide member may have a structure for supporting the label, the structure can be simplified, and the mechanism can be simplified accordingly. Furthermore, since the moving mechanism only needs to move the guide member to the two positions of the guide position and the retracted position, the structure can be simply configured. In this respect, the mechanism can be simplified and the structure can be made relatively inexpensively. Can do.

It is a front view which shows the modification of the label sticking apparatus which concerns on embodiment of this invention. It is a figure which shows an example of the conventional label sticking apparatus. It is a figure which shows the malfunction of the conventional label sticking apparatus.

Hereinafter, based on an accompanying drawing, a label sticking device concerning an embodiment of the invention is explained in detail.
1 to 3 show a label sticking device S according to an embodiment of the present invention. The label sticking device S is a device for sticking a label L to an article W transported by a conveyor (not shown) in the course of transporting the article W, and a strip-like shape in which a plurality of labels L are temporarily attached at equal intervals. The mount D is transferred from a supply reel (not shown) to a take-up reel (not shown). In this transfer process, the label L is printed by a printing mechanism (not shown). The label L is peeled from the belt-like mount D. As shown in FIG. 1, the label peeling unit 1 includes a peeling plate 2 that peels off the label L from the band-shaped mount D by folding the band-shaped mount D and sends it out.

  The label sticking device S according to the embodiment of the present invention includes a holding plate 10 that is provided in the vicinity of the downstream side of the label peeling unit 1 and holds the label L delivered from the label peeling unit 1. The holding plate 10 has a contact surface 11 that comes into contact with the surface of the label L that is peeled off from the belt-like mount D and is sent out, and a holding position X that holds the label L by bringing the surface of the label L into contact with the contact surface 11. (FIGS. 1 and 2) and the back side of the held label L are moved to the two positions of the application position Y (FIG. 3) where the article W is pressed and applied to the article W.

  Specifically, the holding plate 10 is attached to an air cylinder device 12 including a piston 12a and a cylinder 12b that are moved to a holding position X and a sticking position Y. An attachment plate 13 is provided at the tip of the piston 12a, and the back surface of the holding plate 10 is attached to the attachment plate 13 via a cushion mechanism 14 having a spring that absorbs an impact when the label L is applied.

  Moreover, the guide member 20 is provided in the label sticking apparatus S which concerns on embodiment of this invention. The guide member 20 is guided while supporting the back surface of the label L which is sent to the contact surface 11 at the holding position X of the holding plate 10 and guides the surface of the label L in contact with the contact surface 11 (see FIG. 1 and FIG. 2) and the holding plate 10 is retracted from the back side of the label L immediately before reaching the applying position Y, and can be moved to two positions of the retracting position T (FIG. 3) that allows the holding plate 10 to apply the label L. Is.

Specifically, the guide member 20 is configured by a roller that can be rotated about an axis perpendicular to the delivery direction R of the label L and can roll on the back surface of the delivered label. The roller which is the guide member 20 is formed in a spindle shape like a so-called abacus ball in which the circumference of the central maximum diameter is linearly formed, and can rotate around an axis perpendicular to the feeding direction R of the label L. Are supported by a support rod 33 described later.
Further, a plurality of guide members 20 are provided on the left and right of the feeding direction R of the label L of the holding plate 10, and a plurality of guide members 20 are provided along the feeding direction R of the label L of the holding plate 10. In the embodiment, two each are provided at predetermined intervals on the left and right. The number of guide members 20 is not limited to the above.

  In addition, the apparatus includes a moving mechanism 30 that moves the guide member 20. The moving mechanism 30 includes an abutting member 31 that can abut against the article W at the tip, and an arm 32 that supports the guide member 20 via a support rod 33 in the middle of the longitudinal direction. When the holding plate 10 is positioned at the holding position X, the base end 34 side of the arm 32 positions the guide member 20 at the guide position G due to the weight of the arm 32, and when the holding plate 10 reaches the sticking position Y, The support member 35 provided on the upper side of the holding plate 10 can be rotated so that the contact member 31 contacts the article W and the guide member 20 is positioned at the retracted position T as the holding plate 10 moves. Is provided. The support rod 33 pivotally supports the guide member 20 around an axis perpendicular to the delivery direction R of the label L. Further, the contact member 31 is configured by a roller that can rotate around an axis along the delivery direction R of the label L. A shaft 36 that rotatably supports a roller as the contact member 31 is provided at the tip of the arm 32. Since the moving mechanism 30 moves the guide member 20 to the two positions of the guide position G and the retracted position T simply by rotating the arm 32, the mechanism can be easily created accordingly.

Therefore, when the label L is pasted on the article W by the label pasting apparatus S according to the embodiment of the present invention, it is as follows.
As shown in FIG. 1 and FIG. 2, a belt-like mount D temporarily supplied with a plurality of labels L at equal intervals is supplied, and the belt-like mount D is folded at the front end of the peeling plate 2 at the holding position X of the holding plate 10. Thereby, the label L temporarily attached to the belt-like mount D is peeled off, and the label L is sent out in the feeding direction R, that is, toward the holding plate 10. At the holding position X of the holding plate 10, the arm 32 of the moving mechanism 30 is rotated by its own weight, and the guide member 20 is positioned at the guide position G.

  Then, when the label L temporarily attached to the belt-like mount D is peeled off and sent to the holding plate 10, the label L is guided while the back surface thereof is supported by the guide member 20 positioned at the guide position G. Then, the holding plate 10 is gradually moved and brought into contact with the entire contact surface of the holding plate 10. In this case, since the roller which is the guide member 20 rolls and supports the back surface of the label L, the label L is smoothly fed. In addition, the guide member 20 is provided on each of the left and right of the feeding direction R of the label L of the holding plate 10 and supports the label L from the left and right of the sending direction R, so that the support is stable and the label L is securely held. Can do. Further, a plurality of guide members 20 are provided along the delivery direction R of the label L of the holding plate 10, and the labels L are sequentially supported by the guide members 20 sequentially provided along the delivery direction R according to the delivery. As a result, the support is stable and the label L can be reliably held.

  Therefore, since the label L is guided while being supported by the guide member 20, even if the label L is weak, the label L is bent inward in the middle of delivery or the label L is delivered to the end to the holding plate 10. It is prevented that the label L is sent to the holding plate 10 or the label L is sent obliquely, and the holding plate 10 is securely held. Further, since the guide member 20 faces the contact surface 11 of the holding plate 10, the guide member 20 can cope with a relatively short label L.

  Then, as shown in FIGS. 1 and 2, when the entire surface of the label L is brought into contact with the contact surface 11 of the holding body by the guide member 20, the air cylinder device 12 operates, and as shown in FIG. The holding plate 10 is moved from the holding position X to the sticking position Y. In this case, the guide member 20 is moved from the guide position G to the retracted position T immediately before the holding plate 10 reaches the sticking position Y, and is retracted from the back surface of the label L. That is, when the holding plate 10 reaches the sticking position Y, the contact member 31 provided at the tip of the arm 32 of the moving mechanism 30 comes into contact with the article W, and the holding plate 10 moves on the article W as the holding plate 10 moves. And the guide member 20 is positioned at the retracted position T. Therefore, since the guide member 20 does not exist between the contact surface 11 of the holding plate 10 and the article W, the contact surface 11 of the holding plate 10 presses the back surface of the label L against the article W. The label L held on the holding plate 10 is affixed to the article W.

  Then, when the label L is pasted, the air cylinder device 12 is actuated again, and the holding plate 10 is retracted and positioned at the holding position X. Further, the arm 32 of the moving mechanism 30 is rotated by its own weight, and the guide member 20 is positioned at the guide position G. In this way, the label L is sequentially applied.

  Thus, since the label L is guided and supported by the holding plate 10 while being supported by the guide member 20, it is not necessary to give the holding plate 10 an adsorption function as in the prior art. It can be simplified. Further, since the guide member 20 may have a structure for supporting the label L, the structure can be simplified, and the mechanism can be simplified accordingly. Further, since the moving mechanism 30 only needs to move the guide member 20 to the two positions of the guide position G and the retracted position T, the structure can be simply configured. In this respect, the mechanism can be simplified and relatively inexpensive. Can be created. The holding plate 10 may be provided with a suction function. In this case, an appropriate adjustment such as setting the suction force to a weak one is performed. However, since the label L is held by suction, the holding is ensured. Can be.

  In the label sticking device S according to the above-described embodiment, the guide member 20 is configured by a roller. However, the guide member 20 is not necessarily limited thereto. For example, as illustrated in FIG. The roller may be changed to the sprocket 21, and an endless belt 22 may be stretched over the sprocket 21 so that the label L is supported by the belt 22. Further, the moving mechanism 30 is not limited to the above-described arm 32 type, and may be changed as appropriate.
