BACKGROUND OF THE INVENTION
The present invention relates to a label reject device, and more particularly, to a label reject device that can automatically remove a label in which an abnormality is detected by a sensor from a base sheet.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, labels such as IC tags (see Patent Document 1) that resonate with radio waves of a specific frequency have been widely used in retail stores and rental shops to prevent theft of commodities such as CDs. Such a label is generally distributed as a label sheet affixed to a base sheet. At this time, a defective label that does not resonate with radio waves of a specific frequency is detected and detected from the base sheet in advance. Need to be removed. In view of this, there is an inspection device that detects a defective label by a sensor in the process of feeding out a belt-like base sheet and attaches a predetermined mark to the surface of the defective label.
[0003]
However, in such an inspection apparatus, a normal label without a mark and a defective label with a mark are mixed. Accordingly, when such a label sheet is distributed, it is conceivable that a defective label is affixed to a product or the like by overlooking the mark, and it is desirable that the defective label is peeled from the base sheet.
Generally, as an apparatus for peeling a label, for example, an apparatus disclosed in Patent Document 2 exists. The apparatus includes a peel plate capable of turning back a fed-out label sheet, and a holding portion capable of adsorbing a label partially peeled off by the peel plate.

[Problems to be solved by the invention]
However, in such a peeling apparatus, all labels are peeled off, and when a normal label and a defective label are mixed like the label sheet described above, only the defective label is selectively peeled off. It is not suitable for removal.
[0006]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to provide a label reject device that can reliably remove only defective labels and can simplify the configuration. Is to provide.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a label reject device for removing a defective label from a base sheet in a process of feeding out a label sheet including a plurality of labels attached to a belt-like base sheet,
The label sheet is supported by the surface, and at least the downstream end is plate-shaped, a second guide provided on the downstream side in the feeding direction of the first guide, and the second guide A moving means for moving the guide; and a sensor for detecting an abnormality of the label and outputting a signal for operating the moving means in a predetermined manner.
The second guide is normally kept at a position where feeding is allowed with the label attached to the base sheet, while the second guide is downstream of the first guide when the sensor detects a label abnormality. The side end portion is movably provided at a position where it functions as a peel plate. According to such a configuration, it is possible to automatically peel only defective labels out of a plurality of labels. In addition, the first guide can be selectively used as a guide member or a peel plate for the base sheet as necessary, and simplification of the entire apparatus can be achieved.
[0008]
In the present invention, a holding means that is located at the downstream end of the first guide and can hold a defective label, and when the holding means holds a defective label, the defect is in a non-contact state with the defective label. It is preferable to employ a configuration including urging means for urging the label toward the holding means. According to such a configuration, the defective label can be easily and stably removed. In addition, since the label reject device is configured to include both the sensor and the holding means, it is not necessary to separately provide the inspection device and the peeling device, and the production line can be simplified.
[0009]
The urging means is provided so as to be movable together with the second guide by the moving means, and is always kept at a retracted position away from the label sheet, while the retracting means is detected when the sensor detects a defective label. A configuration in which the defective label is moved from the position to a position where the defective label is biased can also be employed. By adopting such a configuration, the position of the urging means can be easily set, and the urging means moves using the moving means, so that the number of parts can be reduced.
[0010]
Furthermore, a configuration in which a pressing member that restricts the lifting of the base sheet when the defective label is removed by the holding means is also preferably employed. In such a configuration, the defective label can be more stably peeled off.
[0011]
In addition, unless otherwise indicated, the term which shows the direction or position in this specification shall use FIG. 1 as a reference | standard.

In this embodiment, the take-up reel 12, the moving unit 16, the stamper 17, the sensor 18, the holding unit 19, the motor 27, the resonance inspection sensor 34, and the moving unit 41 are controlled via a control device (not shown).
[0024]
Next, the overall operation in the embodiment will be described.
[0025]
When removing the defective label L1 in the process of feeding out the label sheet S, first, the resonance inspection sensor 34 detects the presence or absence of resonance at a specific operating frequency in each label L. Here, when the label L does not resonate, a mark M is stamped on the label L by the stamper 17 to obtain a defective label L1 (indicated by a halftone dot in FIG. 2).
[0026]
Next, when the defective label L1 is fed out and the sensor 18 detects the mark M, the sensor 18 outputs a signal to the control device, and the defective label L1 is positioned on the downstream end of the first guide 13. Further, the feeding of the label sheet S is temporarily stopped. In this state, the rod 29 of the moving means 16 is moved backward to move the label sheet S sandwiched between the feed roller 24 and the nip roller 25 in the lower left direction as shown in FIG. The cylindrical member 46 is positioned below the end portion 13A. At this time, the downstream end 13A functions as a peel plate, the base sheet S1 is folded back, and the defective label L is partially peeled from the base sheet S1.
[0027]
Thereafter, the rod 42 </ b> A of the holding cylinder 42 is lowered and the upper surface side of the defective label L <b> 1 is sucked by the suction portion 43. At this time, even if air is blown upward from each hole 46 </ b> A of the cylindrical member 46 and the defective label L <b> 1 is suspended, the defective label L <b> 1 is urged toward the suction portion 43 side so as to be in close contact with the suction portion 43. Next, by raising the suction portion 43, the defective label L1 is completely peeled from the label sheet S1 in a state where the lift of the base sheet S1 is regulated by the bent portion 38 of the pressing member 36. Then, the holding means 42 is slid rightward in FIG. 4 by the moving means 41 and the sucked defective label L1 is placed on the mounting table 40.
[0028]
Thus, after the defective label L1 is removed, the rod of the moving means 16 moves forward, and the delivery roller 24 and the nip roller 25 are returned to the initial positions as shown in FIG. It will evacuate to the position away from.
[0029]
Therefore, according to such an embodiment, since the first guide 13 can also function as a heel plate, the label sheet S from which only the defective label L1 is removed can be easily created. Further, since the urging means 20 is attached to the frame 23, the urging means 20 and the second guide 14 can be interlocked, and the defective label L1 can be quickly peeled off.
[0030]

Therefore, the description limited to the shape disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.
For example, the first guide 13 may have a configuration in which, for example, the downstream end portion 13A is pointed, that is, the plate thickness gradually decreases toward the downstream side in the feeding direction. This is advantageous in that the base sheet S1 can be folded back better.
The moving means 16 can be changed in various designs. For example, a driving rail extending in the moving direction of the second guide 14 is provided on the front surface portion 11, and the second guide 14 is supported by the driving rail. It may be configured to slide. In short, the present invention is provided so that the second guide 14 can be moved so as to allow the feeding of the state in which the label L is stuck to the base sheet S1 and to cause the first guide 13 to function as a peel plate. If it is enough.
The sensor 18 is configured to detect the mark M attached by the stamper 37. However, the sensor 18 has the same function as the resonance inspection sensor 34, and the resonance inspection sensor 34 and the stamper 37 are omitted. May be.
[0031]
【The invention's effect】
As described above, the second guide in the present invention normally allows the label sheet to be fed out with the label attached to the base sheet, while the sensor detects the defective label. Since the structure in which the downstream end portion of the guide can be moved to a position to function as a peel plate is adopted, only the defective label can be easily removed, and the first guide has two functions, that is, a guide member. And by making the function as the heel plate be exhibited, it is possible to achieve simplification of the configuration of the entire apparatus.
[0032]
Further, in the case where the holding means capable of holding the defective label and the urging means for urging the defective label in a non-contact state on the holding means side, the defective label is reliably and stably removed. can do.
[0033]
Further, the biasing means is provided so as to be movable together with the second guide by the moving means between the retracted position away from the label sheet and the position for biasing the defective label. It becomes possible to quickly remove the defective label through easy setting, and it is not necessary to provide a device for moving the urging means in addition to the moving means, so that the number of parts can be reduced.
[0034]
Moreover, when it is set as the structure which further contains the pressing member which controls the raising of a base sheet, a defective label can be peeled more stably.
