DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a transfer device for covering a label tube, which has been cut one by one, over almost the entire container and sending the label tube to the next step.

[0002]

2. Description of the Related Art In recent years, instead of directly printing or labeling bottles made of glass, resin, etc., in recent years, trademarks,
A method is generally used in which a film on which a product name, a pattern, or the like is printed is covered and fixed to a bottle by a method such as heat shrink. Such a method is generally performed by a rotary-type high-speed labeler. However, as is well known, the film is formed into a tube, and the film is continuously supplied in the form of a web, and a cutting section is provided. , And cut into individual pieces, and attached to a bottle that rotates on a turret. One example of such an apparatus is shown in FIGS. In FIG. 4, the bottle 1 transported by the conveyor is supplied to the main turret 42 via the supply star wheel 41. On the other hand, a tube 4 supplied in the form of a web
The pieces 4 are cut one by one as described above, adsorbed on the air piece 45 of the label soccer turret 43, supplied to the main turret 42, and mounted on a bottle on the turret 42. The loaded bottles are sent by a conveyor via a discharge star wheel 46 to the next step, for example a furnace for shrinking.

[0003] The process of mounting the tube on the turret 42 is shown in FIG. The tube 51 supplied from the label soccer turret 43 is adsorbed by the air piece 52 [FIG. 5 (a)] and expanded so as to enable the bottle to be inserted [(b)]. On the other hand, the bottle 1 is gripped by the guide bar and the arm 54 and the like in order to withstand the centrifugal force due to the rotation of the main turret 42 and to maintain its position. Next, the pilot 53, which also serves as a guide for mounting the tube, descends through the expanded tube 51, and suppresses and fixes the top of the bottle 1 [(c)].
In this state, if the arm 54 is opened and the suction of the air piece 52 is stopped in substantially the same manner, the tube 51 falls and is attached to the bottle [(d)]. Next, the bottle is again gripped by the arm 54 from above the tube, and is discharged to the discharge star wheel 46 [(e)].

Conventionally, in order to hold a bottle against a centrifugal force or the like on a turret or a star wheel, a method such as fixing a guard bar outside a bottle passage has been adopted. However, when the bottle comes into contact with the guard bar, rotation occurs, and after the tube is attached, the tube rotates with respect to the bottle due to this contact, causing a mutual positional shift. However, conventionally, the main force of these bottle shapes is a round bottle with a circular cross-sectional shape, and the restriction that the printing part on the tube must be at a specific position in the circumferential direction of the bottle due to the relationship with the bottle shape. There was no problem in the positional relationship between the bottle and the print site on the tube during the process. For this reason, even if the tube and the bottle rotate with respect to each other during the above-described process performed before the tube is shrink-fixed, no problem occurs. In addition, when a label is attached only to the upper part of both a square bottle and a round bottle, the label can be transported without contacting the guide bar, the arm, and other members, so that there is no inconvenience. there were.

[0005]

However, in the case of a bottle that has a non-circular shape such as a square, a hexagon, or a flat ellipse, which is showing signs of fashion in recent years, and that covers the entire container almost entirely, The upper printing section must be on a specific surface of the bottle and cannot be in any position. The tube supplied from the tube feeder has a printing section at a fixed position, and the bottle is also usually supplied in a fixed direction. Therefore, the mounting of the tube on the bottle does not cause much problem. In particular, in a turret in which the top of the bottle is fixed by a pilot as shown in FIG. 5 at the time of mounting, holding by the guard bar is not required, and by preventing contact with the guard bar immediately after mounting,
The shift did not become a problem. However, when the bottle is loosely grasped from above the tube, for example, when the bottle is transferred between the turret and the star wheel, there is a strong possibility that the bottles may be misaligned. An object of the present invention is to provide a container and a shrink label transfer preventing device which do not cause such a problem.

[0006]

A transfer device according to the present invention comprises a holding portion for holding a bottle comprising an opening / closing arm on a rotary transfer portion such as a turret or a star wheel, and the shape of a contact portion of the arm with the bottle. Is similar to the cross-sectional shape of the bottle, and is configured to enable rapid opening and closing at the holding position and the opening position of the bottle. The opening and closing of the arm is performed by a drive piece that closes (opens) the arm urged in the open (closed) direction, which comes into contact with a fixed member as the rotary transfer unit rotates. .

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The essential point of the transfer apparatus of the present invention is that the bottle after the tube is attached is prevented from being displaced by mutual rotation as much as possible. It is desirable to adopt a configuration in which the entire surface of the bottle is grasped instantaneously. One example of the structure of the bottle gripper in the transfer device of the present invention and its function will be described with reference to FIG.

FIG. 3 (a) shows a state in which the bottle 1 is sandwiched, and a pair of arms 2 have substantially the same inner shape as the cross section of the bottle 1 and the outer surface of the bottle along the circumferential shape. It is designed to hold it securely. The arm 2 is fixed integrally with the driving member 4 by a shaft 3, is rotatably mounted on the shaft, and is constantly urged by a spring 8 in a direction to open the arm 2. In the illustrated embodiment, a push body 5 having a substantially rhombic shape is rotatably disposed between the drive members 4, and the push body 5 is fixed to each other by a drive piece 6 and a shaft 7 and integrally formed. Rotate. The arm 2, the pusher 5 and the driving piece 6 are disposed on the turret 10, and rotate integrally with the turret in the direction of the arrow. On the other hand, the position for gripping the bottle 1 and the position for opening the bottle 1 are for opening and closing the arm 2.
The contact rods 11 and 12 are provided. The rotation locus of the tip of the driving piece 6 on the turret 10 is shown by a dotted line in FIG.
The hitting rods 11 and 12 are fixed at positions corresponding to the rotation trajectory.

In FIG. 3 (a), as the turret 10 rotates, the driving piece 6 comes into contact with the contact rod 11 and is rotated. Close,
The bottle 1 is held, and the holding state is maintained by the long diameter of the pushing body 5. In FIG. 3B, when the turret 10 rotates and the arm comes to the opening position of the bottle, the driving piece 6 comes into contact with the hitting rod 12 to rotate the pushing and opening body 5 to open the driving member 4. Then, the arm 2 is opened by the spring 8 to open the bottle. In FIG. 3C, the turret 1
When 0 further rotates and comes to the holding position of the bottle, the tip of the driving piece 6 comes into contact with the hitting rod 11 and is rotated.
Return to the state. In the drawing, reference numeral 9 denotes a stopper that determines the limit of the rotation of the driving piece 6.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a main turret according to a first embodiment of the present invention; FIG. 1 is a partial plan view of the discharge star wheel 46,
FIG. 2 is a side view thereof. The bottle 1, with the tube 1 ′ mounted on the main turret and held by the arm 21, enters between the arm 2 on the star wheel side at the receiving position of the turntable 10 of the star wheel 46, and then the driving piece 6 hits The arm 21 of the main turret is opened by a similar mechanism (not shown), and the bottle 1 is moved to the star wheel by opening the bottle 1 by a similar mechanism (not shown). When the turntable 10 further rotates and the bottle comes to the open position on the conveyor 22, the driving piece 6 comes into contact with the hitting rod 12 and pushes and opens the body 5 (the position is indicated by a dotted line in FIG. 2).
To open the arm 2 and open the bottle. These contact rods 11 and 12 are implanted on a fixed base 13 different from the rotating part of the star wheel. Thus, immediately after the bottle 1 shifts from the turret to the star wheel,
Since the tube and the entire tube are securely held by the arm on the star wheel side, even if the tube 1 'comes into contact with the guide bar during the subsequent rotation of the star wheel, there is no displacement of the tube relative to the bottle.

In the illustrated embodiment, the drive piece 6 controls the opening and closing of the arm by contact with the hitting rods 11 and 12, but is not limited to this. For example, a cam and its follower may be used. Further, although the arm is urged in the opening direction by the spring, it goes without saying that the arm may be urged in the closing direction. Further, in the embodiment, the example in which the transfer device of the present invention is applied to the discharge star wheel has been described, but it is needless to say that the transfer device can be applied to a main turret and other devices. In addition, various design changes of each part of the present apparatus are possible.
