Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking device for sticking a label on the outer peripheral surface of a photographic film cartridge.

[0002]

2. Description of the Related Art As a label sticking device, one disclosed in, for example, Japanese Unexamined Patent Publication No. 2-166038 is known. In this, containers to which labels are to be attached are horizontally conveyed by a conveyor belt at predetermined intervals. A photoelectric switch is provided in the middle of this conveyance path, and when the container blocks the photoelectric path and the photoelectric switch is turned on, the label is supplied from above the container and the label pressing roller reaches the surface of the container in transit. Lower and press the label on the top surface of the container for a period of time. As a result, the label is attached to the top of the container.

On the other hand, in recent years, a photographic film cartridge made of resin has been proposed by the present applicant. For example, as disclosed in Japanese Patent Laid-Open No. 5-72671, a spool around which a photo film is wound in a roll shape is rotatably housed in the cartridge body and the spool is rotated in the film feeding direction. As a result, the leading edge of the photographic film is sent out of the cartridge body from the entrance of the film. For this reason, the cartridge body is composed of two resin parts, and a rib for preventing winding looseness is formed on the inner peripheral wall surface, and a film tip separating claw for separating the film tip portion from the film roll is formed at the entrance of the film passage. I am doing it. The photographic film cartridge disclosed in the above publication has a substantially cylindrical shape. For example, the photographic film cartridge disclosed in Japanese Patent Application Laid-Open No. 5-204093 has a special outer peripheral surface in which a curved surface and a flat surface are combined.

[0004]

Since the label sticking apparatus as described above is intended for sticking only on the upper portion of a flat container, a new type of photograph having the special outer peripheral surface as described above is provided. In order to attach a label to the outer peripheral surface of the film cartridge, it was necessary to change the posture of the photographic film cartridge several times, and it was not possible to attach the label at high speed.

An object of the present invention is to provide a label sticking device capable of sticking a label on the outer peripheral surface of a photographic film cartridge at high speed.

EXAMPLE FIG. 2 and FIG. 3 showing a label sticking apparatus of the present invention
In the above, a large number of pallets 11 are fixed to the conveyor belt 10 at equal intervals, and when the conveyor belt 10 is driven, the pallets 11 are horizontally moved above the conveyor belt 10. A pair of plate cams 12a, 12b, 13a, 1 to be described later are provided on both edges of the conveyor belt 10 along the conveying direction.
3b is arranged.

Above the conveyor belt 10, a label head 14 for feeding and supplying the labels one by one to the conveying path of the photographic film cartridge is supported on the upper part of the column 15. The rotational angle position of the label head 14 in the horizontal plane and the vertical plane can be arbitrarily changed by operating the two handles 16a and 16b. A label 17 with release paper is supplied to the label head 14 in a state of being wound around a label drum 18 in a roll shape. This release paper-attached label 17 is obtained by attaching a strip-shaped label 20 formed on the release paper 19 having a long and continuous length corresponding to the length of the adhered surface of the photographic film cartridge (adhesive layer). The surface coated with is bonded together.

The label 17 with release paper has rollers 21 to 2

However, the label 20 is not completely peeled off, and one end of the label 20 is held in a state of hanging down from the leading end of the edge member 25 with a part left. The long release paper 19 is guided to the release paper drum 30 by the rollers 28 and 29 and wound around it. The label 20 has the surface printed with the sensitivity of the photographic film stored in the photographic film cartridge.

In FIG. 4, a photographic film cartridge 3 is shown.
The Patrone body 33 of No. 2 has two resin parts 34, 3
5, a spool 36 in which a photographic film is wound in a roll shape is rotatably housed. The outer peripheral surface of the cartridge main body 33 is formed by combining a curved surface and a flat surface. A shallow groove 40 corresponding to the thickness of the label 20 is formed in the vicinity of the film entrance / exit 37 formed at the joint between the resin parts 34 and 35 and on the outer peripheral surface of the cartridge body 33 except for the edges on the end surfaces 38 and 39 side. The label 20 is attached here. By attaching this label, the strength of the cartridge main body 33 is improved, and the cartridge main body 33 does not separate even when the photographic film cartridge 32 is dropped carelessly.

As shown in FIG. 1, behind the edge member 25, a label pressing roller 70 made of, for example, elastic rubber or sponge is provided. The label pressing roller 70 is attached to the tip of an arm 71 biased in the counterclockwise direction, and the arm 71 is fixed to the base portion 14a of the label head 14 by a rod-shaped member 72.
It is rotatably attached to the tip of the.

When the photographic film cartridge 32 is conveyed, the front portion 33a presses the label pressing roller 70 via the label 20. As the photo film cartridge 32 is conveyed, the label pressing roller 70 is rotated clockwise as indicated by the chain double-dashed line, and as shown in FIG. 8A, the label 20 is moved to the outer peripheral surface of the photo film cartridge 32. From the front part 33a to the upper part 33b. At the same time, the label 20 is completely peeled off from the release paper 19. After that, the release paper drum 30 is rotationally driven to wind the release paper 19 for a predetermined length, and the next label 20 is projected from the leading end of the edge member 25.

Downstream of the label pressing roller 70, as shown in FIG.
As shown in, three more label pressing rollers 7
4, 75, 76 are sequentially arranged at a predetermined interval. These label pressing rollers 74, 75, 76
Are formed of a material having elasticity similar to that of the label pressing roller 70. In order to avoid complication of the drawing, in FIG. 2, the label pressing rollers 70, 74, 75,
Not shown is 76.

The label pressing roller 74 is urged downward so as to press the upper portion 33b of the passing photographic film cartridge 32 with an appropriate pressing force (see FIG. 8 (B)) and has a constant height. It is regulated not to go below.

The label pressing roller 75 is connected to an air cylinder 78 via an arm 77, and an upper portion of the air cylinder 78 is rotatably attached to a substrate 80 about a shaft 79. Then, the label pressing roller 75
Is urged clockwise by a coil spring 81 together with the air cylinder 78, and a stopper 80 is erected on the substrate 80.
It is pressed against a. When the photographic film cartridge 32 reaches a predetermined position below the label pressing roller 75, the detecting means (not shown) detects this and the conveyance is stopped. At the next moment, the label pressing roller 75 descends,
The urging force of the coil spring 81 presses the rear portion 33c of the photographic film cartridge 32 (see FIG. 8C). The label pressing roller 75 once descends to the height of the rear portion 33c and then moves up and down within the range of the height of the rear portion 33c in the vertical direction. This ensures that the label 20 is attached to the rear portion 33c.

The label pressing roller 76 is installed obliquely and is connected to the air cylinder 83 via the arm 82. Like the label pressing roller 75, the label pressing roller 76 is also rotatably attached to the substrate 84 about the shaft 85, is urged clockwise by the coil spring 86, and is pressed against the stopper 87. When the photographic film cartridge 32 is stopped diagonally below the label pressing roller 76, the photographic film cartridge 32 is detected to descend obliquely downward, and the curved surface portion 3 is biased by the coil spring 86.
3d is pressed (see FIG. 8D). This label pressing roller 76 is also the same as the label pressing roller 75.
After descending to the height of the curved surface portion 33d, the label 20
In order that the end portion of the curved surface portion 33d is surely attached to the curved surface portion 33d, the curved surface portion 33d reciprocates diagonally within the range of the vertical height.

1 and 8, in order to clearly show how the label 20 is attached to the outer peripheral surface of the cartridge main body 33, the groove 40 formed in the outer peripheral surface of the cartridge main body 33 is omitted. I have drawn a drawing.

The operation of the label sticking apparatus thus constructed will be described. First, the label drum 18 around which the label 17 with release paper is wound is attached to the label head 14. The label 17 with release paper is pulled out from the label drum 18 and laid over the rollers 21 to 23, and this is turned around the tip of the edge member 25. At this time, several labels 20 may be peeled off from the release paper 19 in advance. The front end of the release paper 19 is fixed to the shaft of the release paper drum 30 via rollers 28 and 29, and one label 20 is set in a state of hanging down from the front end of the edge member 25.

The photographic film cartridge 32 assembled on another line is conveyed to the upstream end of the label sticking apparatus by a conveyor belt or the like. At the upstream end of the labeling device,
Since the plate cams 12a, 12b, 13a, 13b do not exist, the second support member 43 is at the support position and the third support member 4
4 are set to the retracted position, respectively. A robot arm (not shown) is installed in the vicinity of the upstream end of the conveyor belt 10, and each of the photo film cartridges 32 is held by the robot arm, so that the first support member 42 and the second support member 43 of the pallet 11 are supported. It is placed with the film entrance 37 facing downward. The conveyor belt 10 is stopped during this placing operation.

The photo film cartridge 32 is a palette 1
When placed on the first support member 42 and the second support member 43, the driving of the conveyor belt 10 is started. Pallet 11
Reach the positions of the plate cams 12a, 12b, 13a, 13b, the plate cams 12a, 12b cause the cam receiving shaft 5 to move.
1, 52 are pressed by the plate cams 13a and 13b, and the cam receiving members 65 and 66 are pressed toward the inside of the conveyor belt 10. As a result, the second supporting member 43 is moved to the retracted position and the third supporting member 44 is moved to the supporting position to expose the curved surface portion 33d of the photographic film cartridge 32, and the photographic film cartridge 32 is moved to the third supporting member 44. Held horizontally.

Below the label head 14, a label 20 is provided.
It waits for the photographic film cartridge 32 to arrive with one end thereof hanging from the edge member 25.
The front portion 33a of the photographic film cartridge 32 conveyed here comes into contact with the adhesive layer of the label 20 and presses it, so that one end of the label 20 is between the label pressing roller 70 arranged behind. And is attached to the front portion 33a of the photographic film cartridge 32.

As the photographic film cartridge 32 is conveyed, the front portion 33a of the photographic film cartridge 32 pushes the label 20 together with the label pressing roller 70 to the downstream side. As a result, the label pressing roller 70 is rotated upward and relatively presses the label 20 from the front portion 33a to the upper portion 33b of the photographic film cartridge 32. During this time, the label 20 is completely peeled off from the release paper 19. Further, when the photographic film cartridge 32 is conveyed and reaches below the label pressing roller 74, the label pressing roller 74 presses the label 20 on the upper portion 33b again.

When the photo film cartridge 32 reaches below the label pressing roller 75, the driving of the conveyor belt 10 is stopped. Immediately after this, the label pressing roller 75 is lowered by the air cylinder 80, and the rear half of the label 20 is pressed and attached to the rear portion 33c of the photographic film cartridge 32. Then, the label pressing roller 75 is further moved up and down, and the label 20 is pressed against the rear portion 33c several times. Thereafter, the label pressing roller 75 is raised and the driving of the conveyor belt 10 is restarted.

When the photo film cartridge 32 arrives below the label pressing roller 76, the driving of the conveyor belt 10 is stopped again. Immediately after this, the label pressing roller 76 is lowered obliquely downward from above, and the label 20 is pressed against the curved surface portion 33d. After that, the label pressing roller 76 is further reciprocated, so that the label 20 has the curved surface portion 33.
It is firmly attached to d. After this, the label pressing roller 7
When 6 is raised to the original position where it does not interfere with the conveyance of the photographic film cartridge 32, the driving of the conveyor belt 10 is restarted. When the photo film cartridge 32 to which the label 20 is attached is conveyed to the end of the conveyor belt 10, it slides on the slide plate 88 and is placed on another conveyor belt 89 prepared below, and is packaged through the inspection device. Transferred to the process. The above operation is repeated, and the label is attached to the photographic film cartridge 32 one after another. With the label sticking apparatus of the present embodiment, it is possible to stick a label to a photographic film cartridge at a high speed of about 1 piece / sec.

In the embodiment described above, the pallets are provided with the first and second supporting members for supporting the photographic film cartridge from below, but these are omitted and the third supporting member for supporting the photographic film cartridge from the horizontal direction. It can also be only. In this case, when the photographic film cartridge is placed on the pallet, the robot arm holds the photographic film cartridge between the third supporting members and moves the third supporting member to the supporting position to move the photographic film cartridge to the supporting position. Support. After that, the holding of the photo film cartridge by the robot arm may be released.

Further, in the above embodiment, the label pressing roller 74 is always positioned to press the upper portion of the photographic film cartridge, but the label pressing roller 74 may be raised by the air cylinder after the work is completed. Although it is necessary to stop the conveyor belt below the label pressing rollers 75 and 76, as a means for detecting the arrival of the photo film cartridge 32, a photoelectric switch using a well-known photo sensor or contact of a passing pallet is used. It is possible to employ a micro switch or the like that is turned on by. Incidentally, the label sticking apparatus of the present invention is not limited to the photographic film cartridge having the above-described shape by changing the operation such as the moving direction of the label pressing roller, and the label can be attached to the photographic film cartridge having other shapes. Can be attached.
