DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a band-shaped label to a work.

[0002]

2. Description of the Related Art A film unit with a lens (product name "Sharun Hi") has been provided by the present applicant so that a photographer can easily enjoy photography even when he is not carrying a camera.
Etc.) are provided. This film unit with a lens is obtained by enclosing a unit body in which an unexposed photographic film and an exposure applying mechanism are built in advance with a box-shaped exterior body such as a paper box.

However, since the box-shaped exterior body has a complicated shape, material costs, punching costs and the like are required, and the mounting process to the unit body is complicated, and disassembly at the time of recycling is troublesome. There is. For this reason, the applicant of the present invention has proposed a film unit with a lens in which a band-shaped label is wound around the outer peripheral surface of the unit body instead of the box-shaped exterior body (trade name “Sharprun Super.
Slim, etc.).

By the way, since a raised portion is formed in each part of the unit body, a label having an opening for projecting the raised portion is used. When sticking the label on the outer peripheral surface of the unit body, the label was sucked and held on the suction surface of a suction head made of, for example, rubber, and the suction head was pressed against the front surface of the unit body, and a part of the label was temporarily stuck. Thereafter, a method of applying the label by tracing along the outer peripheral surface of the unit body including a part of the label with a roller has been proposed (Japanese Patent Application No. 7-231702).
issue).

[0005]

However, according to the above-described method, even if the operation control of the suction head is highly accurate, it is impossible to completely press the label around the raised portion by the raised portion disturbing. In this case, the adhesion at that portion is weakened and the portion is easily peeled off. For this reason, the label may be displaced when the suction head is separated or when the roller is traced. In addition, when a part of the label is adhered by tracing the front surface of the unit main body with a roller, the label may not be properly adhered depending on the height of the raised portion. There was a problem that two steps were required to attach a part of the label to the front of the unit body.

The present invention has been made in consideration of the above-mentioned problems of the prior art, and satisfactorily affixes a label having an opening for exposing the raised portion to a work having a raised portion on the outer peripheral surface. In addition, an object of the present invention is to provide a label sticking method that can prevent label peeling and label displacement during work and can shorten the label sticking step.

[0007]

In order to achieve the above object, according to the label sticking method of the present invention, a band-shaped label is suction-held on a suction surface of an elastic suction head, and the suction head is attached to the outer periphery of a work. Pressing against the surface, projecting the ridge provided on the outer peripheral surface of the work from the opening formed in the label, and applying a part of the label while deforming the suction surface of the suction head to the outer circumferential surface of the work The label is attached by pressing the other part of the label along the outer peripheral surface of the work with an elastic member.
In addition, a concave portion is formed on the suction surface of the suction head so that a protrusion provided on the outer peripheral surface of the work enters when the suction head is pressed against the outer peripheral surface of the work.

[0008]

[Function] By holding the label on the suction surface of the suction head,
Press the suction head against the outer surface of the work. Since the suction surface of the suction head has elasticity, it deforms in accordance with the outer peripheral surface of the work. The raised portion provided on the work is exposed from an opening formed in the label, and the label is pressed against the outer peripheral surface of the work without leakage, and a part of the label is attached. Then, the other part of the label is traced along the outer peripheral surface of the work with an elastic member, and is attached. Further, by providing a concave portion on the suction surface of the suction head, when the suction head is pressed against the outer peripheral surface of the work, the raised portion enters the concave portion, and the adhesion increases.

The operation of the thus-configured label attaching device 40 will be described. When the unit main body 2 assembled on another assembly line is conveyed to the end of the belt conveyor 47, it is fixed to the jigs 48a and 48b by a robot arm installed near the end of the belt conveyor 47. When the belt conveyor 47 is driven and the unit body 2 arrives at the first station 41, the winding rollers 56
As a result, the release paper 54 is wound up for a certain length, and one label 3 is fed out in a substantially horizontal direction while peeling off from the release paper 54. At this time, the movable portion of the X-direction positioning cylinder 59 has been extended, and the suction head 57 has been moved in advance to the vicinity of the tip of the edge member 55 as shown by the two-dot chain line in FIG.

The label 3 is attached to the suction surface 57a of the suction head 57.
Of the label 3 is detected by a sensor switch (not shown) or the like, the driving of the suction head 57 is started, and the label 3 is suctioned to the suction surface 57a. When the label 3 is sucked on the suction surface 57a of the suction head 57, the edge 3a of the label 3 protrudes from the cutouts 57b to 57e of the suction head 57. Subsequently, the X-direction positioning cylinder 59 is driven, and the suction head 57 is horizontally moved in a direction away from the edge member 55 (X-direction). This movement is performed by the notches 57b to 57d of the suction head 57.
Is performed to a predetermined position where the bottom surface of the label 3 comes into contact with the reference guides 61 to 63, during which the edge 3a of the label 3 protruding from the notches 57b to 57d comes into contact with the reference guides 61 to 63 to position the label 3 in the X direction. Is performed. Thus, even if the label tape 53 has a variation in the punching position of the label 3 and the position where the label 3 is sucked to the suction surface 57a of the suction head 57 is not constant, the label 3
Is corrected to a predetermined correct position.

Subsequently, the Y direction positioning cylinder 60 is driven, and the suction head 57 is moved in the Y direction together with the X direction positioning cylinder 59. When the Y-direction positioning sensor 60 detects the edge 3b of the label 3 protruding from the notch 57e, the detection signal is input to the computer 66. Thus, the driving of the Y-direction positioning cylinder 60 is stopped, and the label 3 is positioned in the Y-direction. In the positioning in the Y direction, the stop position of the suction head 57 is determined by detecting the edge position of the label 3, so that the position of the label 3 in the Y direction is correctly determined even if the suction position of the label 3 varies. Will be modified.

Thereafter, the sticking cylinder 58 is driven,
The suction head 57 is lowered toward the front surface of the unit body 2 below. At this time, since the positioning of the label 3 in both the X and Y directions is performed accurately, the opening 3
1 and the position of the raised portion 10 of the unit main body 2 coincide with each other, so that a part of the label 3 does not contact and stick to the raised portion 10. As the suction head 57 descends, the protrusion 10 protrudes from the opening 31 and enters the recess 57f, and the suction surface 57a is deformed in accordance with the front surface of the unit main body 2 and the front cover 26 of the label 3 is moved to the unit main body 2
Adhere to the front of the. The label 3 is adhered to the front surface of the unit body 2 by the adhesive applied to the rear surface.

The front surface of the unit main body 2 is formed with a gentle curved surface, and a concave portion is formed in a portion where the finder objective lens 17 is exposed, but the suction surface 57a is deformed according to the front surface of the unit main body 2. Therefore, the front cover portion 26 of the label 3 can be stuck to the front surface of the unit body 2 without any contact. For example, when the suction head 57 is pressed against the front surface of the unit main body 2 at a pressure of 1 kg / cm ² , the floating of the label near the edge of the unit main body 2 caused by a decrease in the adhesive force of the label due to aging or the like is completely prevented. This is evident in tests by the applicant.

Next, the belt conveyor 47 is driven to drive the unit body 2 to which the front cover 26 of the label 3 is adhered.
Is transported to the second station 42. Unit body 2
Arrives at the second station 42, the pressing brush 73 descends, and presses the upper cover 25 of the label 3 against the upper surface of the unit body 2. The pressing brush 73 is used for the label 3
The upper surface cover 25 is moved while tracing the upper surface cover 25 and pressing the upper surface of the unit body 2. Thereafter, the belt conveyor 47 is driven, and the unit main body 2 is transported to the third station 43.

In the third station 43, the pressing brush 7
7 moves from right to left, and presses the rear cover 24 of the label 3 against the rear of the unit body 2. The pressing brush 77 moves while tracing the rear cover part 24 and presses and adheres to the rear surface of the unit body 2. Thereafter, the belt conveyor 47 is driven, and the unit body 2 is transported to the fourth station 44.

In the fourth station 44, the side edges of the label 3 are detected by the deviation detecting sensors 79a and 79b, and the deviation of the label 3 is checked. When the displacement of the label 3 is not detected, the unit body 2 is sent to the fifth station 45. If a displacement of the label 3 is detected, the label 3 is sent to another step to peel off the label 3 and then sent to the first station 41 again.

In the fifth station 45, the pressing brush 8
1 moves from bottom to top and presses the overlapping portion 27 of the label 3 against the bottom surface of the unit body 2. The pressing brush 81 moves while tracing the overlapping portion 27 and presses and adheres to the bottom surface of the unit body 2. Thereafter, the belt conveyor 47 is driven, and the unit body 2 is transported to the sixth station 44.

In the sixth station 46, the pressing brush 8
6 moves from top to bottom and presses the bottom cover 23 of the label 3 against the bottom of the unit body 2. The pressing brush 86 moves while tracing the bottom cover portion 23, and
Press on and paste.

In the above embodiment, the pressing head is formed of sponge, but may be formed of soft rubber or vinyl. Further, instead of the brush, the label may be attached using a roller or the like having an outer periphery made of rubber or sponge. The label material is PET
Besides polystyrene and synthetic paper, polystyrene (PS), polypropylene (PP) and the like can be used. Also, depending on the shape of the raised portion, it is not necessary to provide a concave portion on the suction surface of the suction head. There is also a method of giving the label a stiffness (intentionally bending) without using the suction head 75, or supporting the label with air or a member that is difficult to adhere.

Although a pair of reflective sensors are used in the fourth station as a means for detecting the displacement of the label, the area of the transmissive sensor or the unattached portion between the raised portion and the opening edge from which the raised portion is detected is determined by the line sensor. For example, the image data may be read and image processing may be performed, and the resulting image data may be compared with regular data to detect a deviation. In addition, the displacement may be detected by reading the shape of the unattached portion between the opening edge and the raised portion. There is also a method in which a transport method for attaching a label to the unit body is used, and an index table for intermittent feeding is used. There is also a method of sticking and folding in a continuous operation without stopping for each unit.

Further, a blower is arranged beside the label supply device so that the label is stably sucked by the suction head, and assist air is constantly blown near the tip of the edge member from which the label is fed out. It may be. Also,
The blower may be provided with a static elimination function and blow an ion wind for preventing charging of the label, so that the blower also serves as the assist air.

Further, in the above embodiment, the case where the label is attached to the unit body is selected, but the present invention can be applied to all label use fields.

[0040]

As described above, according to the label sticking method of the present invention, the band-shaped label is suction-held on the suction surface of the head, and the suction head is pressed against the outer peripheral surface of the work to form the label. Attach a part of the label while projecting the ridge provided on the outer peripheral surface of the work from the opening, and deforming the suction surface of the suction head to match the outer peripheral surface of the work. By sticking by pressing along the outer peripheral surface of the work with the member,
Part of the label can be attached regardless of the shape of the work. Since the other part of the label was traced along the outer peripheral surface of the work with an elastic member, it was attached.
The label attaching process can be shortened.
