Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bellows supporting device in a label sticking device in which a thin label is temporarily held by suction of a bellows and then the label is stuck to an adherend (product) by a bellows that is expanded by air pressure. Out.

[0002]

[Prior art]

 As a label sticking device for sequentially sticking a label made of a thin plastic film or the like to a bellow by suction and holding, for example, a label sticking device disclosed in Japanese Patent Publication No. 57-48458 is known. This device divides the fed tape-like label mount into left and right parts along the separation edge of the V-shaped notch, and turns over only the label mount, and also one peelable label located in the center of the label mount. A separator part that is delivered as an address, a flexible hose that faces the upper part of the separator part and that holds the peeled label by suction, and a bellows that communicates with this are arranged on the upper and lower surfaces of the movable bellows support plate. For example, the raw device unit has a structure in which a label suction vacuum generator unit arranged at the base of the flexible hose and an air pressure generator unit for pressing the label against the adherend are combined. In this case, the movable support plate of the bellows unit can be slid in the longitudinal direction with the slider to the retracted and raised position for holding the label with the bellows overnight and the forward and lowered position for pressing the adherend. It has a structure (see Fig. 7).

[0003]

[Problems to be solved by the device]

 However, since the movable bellows support plate a is slid back and forth by the sligoo c that reciprocates through the towing plate b attached to the support plate a, high-speed label sticking was inevitable. . Further, in this case, both side ends of the bellows support plate a are fitted and guided at the front and rear positions in the guide slots d and e, and particularly, the guide slot d at the front part is provided with upper and lower guide spring pieces f and g. It has a two-stage h, i structure. When it is fed forward (when a label is attached to an adherend), it moves to the lower stage i, and when retracting it moves to the upper stage h and then slides backward. Since the crank motion method is adopted, high-speed slide cannot be expected from this point as well, and the spring pieces f and g are easily damaged.

In view of the above situation, the present invention adopts a swing method in which a movable bellows supporting plate having a flexible hose or bellows serving as an air passage for adsorbing and attaching a label is lifted and lowered by a cam displacement. Then, it aims at providing the bellows support apparatus in the label sticking apparatus which solves the said subject.

[0005]

[Means for Solving the Problems]

 According to the present invention, a label strip formed by attaching predetermined labels to a mount tape portion having a separation line at the center in the longitudinal direction at regular intervals is divided into left and right by a V-shaped peeling plate, and the sheets are reversed and fed. The label peeled from the mount tape is slid on the bellows support plate. It is temporarily held by the negative pressure on the bellows at the end of the flexible hose and is pneumatically extended to the adherend conveyed below the bellows support plate. In the label sticking device for pressing and sticking the label held at the bellows end, the front and rear ends of the bellows support plate main body are suspended by a support link of a link mechanism whose fulcrum is the upper end, and one of them is swingable. The support link and the fulcrum shaft are integrated, and the cam follower of the driving arm, which is separately provided at the end of the fulcrum shaft, is fitted into the cam groove of the rotating cam body that interlocks with the motor to change the cam position of the cam follower. Hara to follow The swinging of the arm via a pivot shaft transmitted to the support link is for the shaken and the elevation between both supporting lifting link and the bellows support plate body.

[0006]

[Action]

 As described above, the label strip formed by sticking the label is fed to the V-shaped peeling plate position, the mount tape portion is divided by the peeling plate portion, and the V-shaped peeling plate is divided along the respective edge surfaces. If it is turned over, the label attached to the surface of the mount tape is peeled off. At this time, the bellows support plate at the front position moves up and down due to the swing (swing) of the hanging support link, the bellows end faces directly above the label, and the bellows support plate swings by the support link. When descending, the negative pressure applied to the bellows temporarily sucks and holds the label on the bottom surface of the bellows. In this state, the bellows support plate further descends forward due to the return swing of the support link, and the bellows end faces the position directly above the adherend to be fed downward. Here, air pressure is applied to the bellows to extend the bellows, and the sticky bear label is pressed against the adherend to be stuck. The oscillating swing of the bellows support plate is performed by continuous rotation that serves as a follower node of the driving arm in which the base end shaft of one support link follows the cam displacement of the Kaku follower fitted in the cam groove of the rotating cam body. .

【Example】

 The present invention will be described below with reference to the drawings of the embodiments. 1 is a label strip having a separating line 2 at the center in the longitudinal direction of a mount tape portion 1'having a surface coated with a release agent, and having labels 3 of a predetermined shape attached at regular intervals. The supply reel 4 on which 1 is wound is mounted on a vertical machine frame 5, and the label strip 1 pulled out from the supply reel 4 is horizontally attached to the vertical machine frame 5 through appropriate tension rollers 6a, guide rollers 6b, etc. In the V groove 8 formed at the tip of the arranged V-shaped peeling plate for label 7, the mount tape portion is separated along the separation line 2 along the inclined edges 8a and 8b each having a 45 ° inclination to the left and right of the V groove 8. 1'is guided while not being divided into two, the divided mount tape portions 1a ', 1b' are inverted to the lower surface, and further inverted by the inclined edges 9a, 9b provided at symmetrical positions again to be separately wound. It is arranged to lead to a take-up reel (not shown). Reference numeral 10 is a slide-type bellows support plate facing directly above the label peeling point which is the tip portion of the V-shaped peeling plate 7. The bellows support plate 10 connects the front and rear ends of the bellows support plate body 11 having the guide rod 11a. , A kind of link mechanism in which the upper end of the fulcrum shafts 12 and 12 are pivotally attached to the vertical machine frame 5 side and which can be oscillated and suspended by a pair of support links 13 and 13, and one of the fulcrum shafts 12 An integral driving arm 14 is attached to the end of the driving arm 14, and a cam follower 15 attached to the tip of the driving arm 14 is interlocked by an actuating motor 16 that constantly rotates through a transmission mechanism 17 to form a cam groove of a rotating cam body 18. The fulcrum shaft 12, which is a base end of the driving arm 14 that is fitted to the cam 19 and moves in response to the cam displacement, is rotated in the front-rear direction by a predetermined width, and the support links 13 and 13 are shaken in accordance with the rotation width. Shake, bellow support plate body 11 is swung to be a parallel movement. A flexible hose 20 serving as an air hose that connects to a negative pressure / pressurization generator 27 is attached to the upper part of the bellows support plate body 11, and the bellows support plate body 11 facing the flexible hose 20 is attached. The lower part of the structure has a structure in which an expandable bellows 22 having a plurality of suction holes 21 is provided on the lower surface so as to project.

Reference numeral 23 denotes a timing belt arranged on both sides of the bellows support plate 10. Reference numeral 24 is a support arm having one end attached to both sides of the V-shaped peeling plate 7 pivotally attached thereto, and the support arm 24 is provided with a position return spring 25. Reference numeral 26 denotes a label feeding connecting rod provided on one side of the bellows support plate body 11.

Next, this operation will be described. When the label 3 is sucked at the position of the V-shaped peeling plate 7 and pressure-adhered at the feeding position of the adherend A, the bellows support plate 10 swings and slides. First, in the label peeling step, the label strip 1 fed through a predetermined path is fed to the V-shaped peeling plate 7 and is formed on the inclined edges 8a and 8b of the V groove 8 which is inclined 45 ° to the left and right. Flip along the bottom. At this time, the mount tape portion 1'constituting the label strip 1 has a separating line 2 in the center and becomes a bear which is split left and right, so that the label 3 is inevitably separated and peeled.

When the label 3 is peeled off, the bellows 22 disposed on the lower surface of the bellows support plate 10 faces the position directly above the label 3 at a predetermined timing, and a negative pressure is applied to the bellows 22. The label 3 is once held by the suction action resulting from the negative pressure from the device 27.

That is, the bellows support plate 10 has a link mechanism in which the bellows support plate body 11 is suspended by the front and rear support links 13 and 13, and is integrated with the upper end of one of the support links 13. The cam follower 15 mounted on the driving arm 14 at the end of the fulcrum shaft 12 supported by the bearing 28 swings due to the cam displacement of the cam groove 19 of the rotary cam body 18 interlocked with the actuating motor 16 and becomes a follower shaft. 12 rotates a certain angle, the support link 13 integral with the fulcrum shaft 12 is swung, and the bellows support plate body 11 swings backward by a parallel motion and ascends and slides. The bellows 22 themselves also contract by negative pressure and reach the upper surface of the label 3 (see FIG. 4).

In this way, the bellows support plate 10 that once holds the label 3 slides in the downward direction due to the cam displacement of the rotary cam body 18 received by the cam follower 15 on the support links 13 and 13 contrary to the above. , Moves directly above the feeding standby position of the adherend A. At this time, the bellows 22 is still in a contracted state.

Next, pressurized air is applied to the bellows 22 by the pressure generating device 27, and the bellows 20 are expanded to press the label 3 located on the lower surface against the upper surface of the adherend A for sticking. (See FIG. 4, one-dot chain line).

That is, since the bellows support plate 10 constantly reciprocates with a predetermined swing (swing) in parallel movement from the label peeling position to the feed standby position of the adherend, high-speed label sticking can be performed.

[0015]

[Effect of device]

 As described above, the bellows support device in the label sticking device of the present invention is a driving arm in which the bellows support plate body is suspended by a pair of support links, and one support link is provided with a fulcrum shaft end that is integral with the support arm. Since the cam follower of is fitted in the cam groove of the rotating cam body that is always rotating, this cam displacement is converted into rotation of the fulcrum shaft, and the bellows position can be moved by a simple swing movement that causes parallel movement to the support link. It is most suitable for high-speed label attachment (does not require a complicated moving process such as a combination of reciprocating movement of bellows support plate and vertical shift movement due to groove regulation as in the past). Moreover, since the cam mechanism is used, the structure is extremely simplified and, in the end, the mechanical members are not damaged or broken.
