Description

  The present invention relates to a label sticking apparatus and a label sticking method, and more particularly, to a label sticking apparatus and a label sticking method for peeling off a label temporarily attached to a mount and sticking it to an object.

  Some label affixing devices separate labels that are temporarily attached to a belt-like mount at regular intervals, and affix them to an object. In this label sticking device, the belt-like mount is fed so as to be folded back by the peeling plate, and the label is sucked and peeled off by the suction disk at the folded portion.

  However, in such an apparatus, the label remains adhering without being glued from the belt-like mount in a state where the label is adsorbed. At this time, the label may be dragged to the mount and displaced, and the label may be attached obliquely.

  On the other hand, a technique is known in which the label is easily separated from the mount by rotating a member in a direction in which the mount and the label are separated when the mount is separated from the label (see, for example, Patent Document 1).

JP 2003-81234 A

  However, when the member that rotates in the direction in which the mount and the label are separated rotates to separate the mount and the label, the mount is loosened, the label is displaced, and the label is not attached to the object to be pasted. The position may shift.

  As a method of removing the slack of the mount, there is a method of installing a dancer roller, but this method has poor responsiveness and the mechanism is complicated, so introduction is difficult.

  The present invention has been made in view of the above points, and even when a member that rotates in a direction in which the mount and the label separate from each other rotates to separate the mount and the label, the mount does not loosen the label. An object of the present invention is to provide a labeling device that does not cause misalignment.

  In order to achieve the above object, the present invention provides a label sticking device in which a label suction part peels a label from a mount and sticks it to an object, and is a folding corner provided at a position facing the label suction part. And a first member that peels off the label from the mount by rotating the folding corner, and a second member having a rotational power mechanism, and rotating the first member. The second member rotates prior to.

  According to said structure, since the 2nd member rotates prior to the operation | movement of a 1st member, the slack of a base_sheet | mounting_paper can be prevented. As a result, the mount and the label can be separated with high accuracy, so that the label on the object can be applied with high accuracy.

It is the schematic which shows the structure of the label sticking apparatus of 1st Embodiment. It is the figure which looked at the label conveyance surface of a 1st embodiment from the front. It is an enlarged view which shows the label peeling part of FIG.1 (b). It is an enlarged view of the label peeling part of FIG.1 (c). It is the schematic which shows the structure of the label sticking apparatus of 2nd Embodiment.

Embodiments of the present invention will be described below in detail with reference to the drawings.
(First embodiment)
Fig.1 (a) to (d) is a schematic diagram showing the configuration of the label sticking device of this embodiment. The label sticking apparatus of this embodiment includes a label supply unit in which the supply reel 1 is set, a label suction unit 5, a first member 6, a second member 7, and a mount feed roller 8. The supply reel 1 is composed of a roll around which a mount 2 on which a label 3 is temporarily attached is wound. The label suction unit 5 is disposed in front of a label transport surface on which a label temporarily attached to the mount 2 is transported, and sucks and holds the label 3 to be attached to an object. The mount feeding roller 8 moves the mount 2 by sandwiching and rotating the mount 2. The first member 6 rotates at the corner of the label sticking device to peel the label 3 from the mount. The second member 7 disposed between the first member 6 and the mount feeding roller 8 has a rotational power mechanism such as a motor 11 and rotates prior to the operation of the first member 6.

  The first member 6 is fixed to a part of the label affixing device by a spring 4, and the first member 6 is pulled without any slack after the mount 2 is pulled by the rotation of the second member 7 having the rotational power means. 6 rotates. The shape of the first member 6 is preferably a substantially triangular shape because the label 3 is peeled off using the folded corner and rotated. Further, in order to prevent the mount 2 from being cut when the mount is fed, a roundness of about R1 to R2 is provided at the tip of the peeling portion.

  The initial position of the first member 6 is set to be horizontal with respect to the label conveyance surface so that the label 3 can be easily conveyed to the label suction unit 5. The initial position of the first member 6 is pulled up by the spring 4, but as shown in FIG. 2, the end facing the end pulled up by the spring 4 to maintain the horizontal position is a stopper. 12 is fixed. Therefore, the upper part of the first member 6 does not go above the horizontal position of the label conveying surface.

  The rotation angle of the first member 6 and the second member 7 may be a rotation angle that allows the mount 2 to retreat to a position that does not hinder the movement of the label 3 held by the suction member. Good. However, in this embodiment, in order to retract more reliably, it is rotated at an angle of 45 ° to 90 °.

  In the present embodiment, the first member is pulled up by the spring. However, the present invention is not limited to the spring, and any elastic member may be used as long as the first member is pulled up to a predetermined position.

  Next, the basic operation of the label sticking device of this embodiment will be described.

  The mount 2 is fed by the rotation of the mount feed roller 8 from the initial state shown in FIG. Then, as shown in FIG. 1B, the label 3 moves to the label suction unit 5. Next, prior to the rotation of the first member, the second member 7 rotates in a direction to remove the slack of the mount 2 of the peeling portion, and the mount is stretched without slack. And as shown in FIG.1 (c), the 1st member 6 rotates with the state maintained, and separation | separation of the base_sheet | mounting_paper 2 and the label 3 is completed.

  FIG. 1D is a diagram illustrating a state in which the separation of the mount 2 and the label 3 has been completed.

  The label suction unit 5 that sucks and holds the label 3 moves to the object 10 and affixes the label 3 to a predetermined position of the object 10. When the label 3 is attached to the object 10, the second member 7 is rotated toward the initial position by the motor 11, and then the first member 6 is pulled by the tension of the spring 4 to return to the initial position. Return to the initial state shown in 1 (a). Therefore, it returns to the initial position while the tension of the mount 2 is maintained.

  Thus, according to the label sticking method of this embodiment, since there is no slack of the mount 2 in the initial state, a predetermined amount can be sent when the mount 2 is sent.

  Next, the relationship between the tension and torque generated in the first member 6, the second member 7 and the mount 2 of this embodiment will be described.

First, when the mount 2 is fed by the mount feed roller 8, if the tension generated on the mount 2 is F4 and the breaking force of the mount 2 is F3, when the mount is fed to suck the next label, In order not to break, the following relationship must be established.
F3> F4

Further, when the tension generated on the mount by the rotation of the second member 7 is F2, and the force at which the mount 2 is broken is F3, the following relationship is necessary to prevent the mount from being broken by the tension due to the rotation when the second member 7 is rotated. Need to hold.
F3> F2

  Next, the torque relationship will be described.

FIG. 3 is an enlarged view showing the label peeling portion of FIG. 3 and 1B, the tension of the spring 4 is F1, the horizontal distance from the rotation center of the first member 6 to the connection portion of the spring 4 of the first member 6 is L1, and the first member 6 A linear distance to the mount 2 between the rotation center and the first member 6 and the second member 7 is L2. Since the first member 6 should not rotate when the mount 2 is fed, the following relationship needs to be established.
F1 × L1> F4 × L2

FIG. 4 is an enlarged view of the label peeling portion of FIG. As shown in FIG. 4 and FIG. 1C, when the linear distance from the rotation center of the second member 7 to the mount 2 between the first member 6 and the second member 7 is L3, the rotation of the second member 7 is performed. Therefore, in order for the first member 6 to rotate, the following relationship needs to be established.
F1 × L1 <F2 × L3

Further, in order to rotate the first member 6 without breaking the mount 2, the tension F2 generated on the mount 2 by the rotation of the second member 7 is preferably as small as possible. The first member 6 rotates when the following relationship is established.
F1 × L1 <F2 × L2

  Therefore, in order to reduce F2 and rotate the first member 6, the distance L2 may be increased. Increasing L2 means increasing the mount angle A between the first member 6 and the second member 7, as shown in FIG. The angle A may be as large as possible within a range larger than the tip angle B of the first member and smaller than 90 °.

Theoretically, the angle A should be increased as much as possible, but if it is too large, there is a possibility that when the mount 2 is fed, it may move to the take-up side with the label 3 attached to the mount 2, so that the label is adhered. When the force is about 10 N / mm ² , it is preferably set to 10 ° to 20 °.

  As described above, in the label sticking device of the present embodiment, since the mount 2 does not loosen when the first member 6 rotates, there is no positional deviation of the attracted and held label 3, and the mount of the mount by the rotation of the first member 6. 2 and label 3 can be more completely separated. And a simple and inexpensive label sticking apparatus can be provided.

(Second Embodiment)
FIG. 5 is a schematic diagram showing the configuration of the label sticking device of the second embodiment. In the present embodiment, the first member 6 and the second member 7 are each provided with a motor 11 (rotational power mechanism). The first member 7 includes a torque sensor 13 that detects torque applied to the second member 7.

  In the label sticking device of the present embodiment, when the movement of the label 3 to the label adsorbing unit 5 is completed, the second member 7 rotates in a direction in which the slack of the mount 3 of the first member 6 can be removed prior to the rotation of the first member. Begin. When rotation starts, tension is generated in the mount 2. Next, the tension of the mount 2 is detected by a torque sensor 13 installed inside the motor of the first member 6, and when the previously set tension (for example, 15 N) is reached, the motor 11 installed on the first member 6. Begins to rotate. And the 1st member 6 and the 2nd member 7 rotate, maintaining the relationship where the change of the value of the torque sensor 13 installed in the 1st member 6 does not arise.

  In the operation of the present embodiment, it is possible to easily and finely set the operation stroke and the set torque of the first member 6 and the second member 7 by electrical control.
