Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for applying labels to the surface of bottles.

Conventionally, glue was applied to the adhesive side of the take-out plate, this adhesive side was pressed against the back side of the label stored in the magazine, and the adhesive force of the glue was used to stick it to the adhesive side and take it out from the magazine. There is a well-known bottle labeling device in which the bottle is gripped and peeled off from the adhesive surface, and the glue transferred from the adhesive surface is used to stick it to the surface of the bottle. Since the adhesive is applied by rolling the adhesive roller over the surface, the adhesive gradually accumulates in the relief groove into which the label retaining claw and gripping member enters, and the label is removed from the magazine. When taking out the label and peeling off the label, glue adheres to the locking claw and the gripping member, and further,
If this accumulates, the label may become stuck and fail to be removed, or the gripping member may not work properly and the label may not be peeled off.Also, if the device is temporarily stopped, the glue may dry and the label may not be removed. There were problems in which the adhesive force was lost and the label could not be removed from the magazine, or conversely, the label stuck firmly to the adhesive surface and could not be peeled off.

The bevel gear 37, which is meshed with the second drive gear 36 and normally rotates integrally with the second drive gear 36, is continuously rotated in the same direction as the rotary table 1 at the same speed. The four meshing bevel gears 22 are configured not to rotate, and the second drive gear 3 is rotated at predetermined intervals.
6 is cut off from the drive source, and the rotation of the bevel gear 37 is stopped for a short time. During this time, the four bevel gears 22 meshing with the bevel gear 37 roll and rotate by a certain angle, and accordingly, When the threaded rod 21 rotates,
The moving body 24 is moved outward by a certain distance.

A magazine D containing a large number of labels d stacked with their backs facing forward is arranged adjacent to the mounting device C described above, and the stacked labels d are pushed forward by the elasticity of the coil spring 40. It is pressed and biased and is locked by locking pawls 41 formed inwardly on both left and right sides and on both top and bottom sides of the front end of the magazine D. Moreover, this magazine D is at the same height as the solid glue 2, and its front end is the same as the solid glue 2.
The front surface of the rotary table 1 slightly protrudes inside the trajectory circle drawn by the rotary table 1, and its axis is swung to the right of the position facing the center of the rotary table 1, as shown by the reference numeral in FIG. Therefore, when magazine D is viewed from the back, the left edge of the front end of magazine D is positioned on the trajectory circle of the solid glue 2 described above,
As shown by the symbol in the figure, the axis is swung to the left and the right edge of the front end is positioned on the trajectory circle. When the front edge of the solid glue 2 in the front rotation direction reaches the left edge of the front end of the magazine D due to the clockwise rotation of the rotary table 1, the rotation of the rotary table 1 stops. When the front rear edge of the solid glue 2 and the right edge of the front edge of the magazine D are swung to the corresponding left side, the It swings back to the position in which it was swung to the right, and swings left and right in synchronization with the rotation of the rotary table 1.

Furthermore, the pasting device E is adapted to continuously rotate counterclockwise at the same speed as the rotary table 1 of the take-out device C, and has a movable finger 50 attached to the tip thereof at a position corresponding to the solid glue 2. A total of four pairs of gripping members 3 are installed at 90 degree intervals, and a pad 51 is provided between the pair of gripping members 3.
are provided so that they can move forward and backward, and pressurized air is blown out from both sides.

Next, the operation of this embodiment will be explained.

By driving the first drive gear 12, the rotary table 1 rotates clockwise in FIGS. 1 and 2, and at this time, the second drive gear 36 is also driven and the bevel gear 37 1, the four bevel gears 22 that mesh with the bevel gear 37 do not rotate, and the solid glue 2
rotates clockwise while keeping its front position at a constant distance from the center of rotation of the rotary table 1. and,
When the front edge of the solid glue 2 in the rotation direction reaches the left edge of the front edge of the magazine D, which is waiting in a right-swinging position, the magazine D rotates counterclockwise at the same speed as the rotary table 1. While swinging in the direction,
The locking pawl 41 formed on the front edge of the magazine D is
Since each solid glue 2 enters the corresponding relief groove 19, while the magazine D swings, the front surface of the solid glue 2 moves from the front edge to the rear edge in the direction of rotation, and the front surface in the magazine D sequentially moves. The label d is pressed from the left edge to the right edge of the label d, and the front label d aligns and sticks to the front of the solid glue 2, and is taken out from the magazine D.

Subsequently, about 90% of solid glue 2 with label d attached is applied.
When the applicator E is rotated once, the left and right gripping members 3 of the applicator E, which are rotating in the opposite direction at the same speed as the rotary table 1, first hold the gripping member 3 at the front of the applicator E in the rotational direction. Finger 50 is solid glue 2
enters into the relief groove 19 and the left edge of the label d is gripped, and as the solid adhesive 2 and the gripping member 3 rotate, the label d is gradually peeled off from the front of the solid adhesive 2, and is completely peeled off at the same time. , the fingers 50 of the rear gripping member 3 touch the escape groove 19 on the other side of the solid glue 2.
The right edge of label d is grasped. Then, the label d is gripped on both sides by the fingers 50 of both gripping members 3, and is transported with the pasted back side facing outward. On the way, the gripping members 3 protrude forward while narrowing the corresponding interval, and about When the label is rotated 180 degrees and transferred to the front of the bottle c held by the holder b on the conveyance line A, the pad 51 moves forward and presses the center of the label d against the surface of the bottle c. The fingers 50 of both gripping members 3 open, and pressurized air blows out from both sides of the pads 51.
Label d is pasted on the surface of bottle c.

The solid glue 2 described above is preferably one that does not harden in a short time when exposed to air and does not easily deform when pressed against the label d.

Through the above procedure, the label d is attached to the front surface of the solid glue 2, taken out from the magazine D, peeled off by the attaching device E, and sequentially attached to the surface of the bottle c. The glue 2 is gradually consumed and its front position gradually retreats. Therefore, at predetermined intervals, the second drive gear 36 is driven for a short period of time corresponding to the movement of a specific solid glue 2 from the front of the magazine D to a position adjacent to the pasting device E. When disconnected from the source, bevel gear 3
7 is stopped for a short period of time, and the four bevel gears 22 meshing with the bevel gears 22 rotate by a certain angle, whereby the threaded rod 21 also rotates and the movable body 24 moves outward, and is integrated with this movable body 24. The pressing plate 31 presses the back side of the solid glue 2 to advance the solid glue 2 by an amount commensurate with the amount consumed on the front side, and the front position of the solid glue 2 is maintained at a constant distance from the center of rotation of the rotary table 1. It is possible.

Note that instead of the above embodiment, the magazine D is fixed and the solid glue 2 is made to be able to swing.
The rotary table 1 and the pasting device E are synchronized and intermittently rotated, and the solid glue 2 is pressed against the label d on the front side of the magazine D and then swung to stick it and take it out. Once rotated 90 degrees, grip both edges with the gripping members 3,
The solid glue 2 may be peeled off by swinging again. In this case, the second drive gear 36 also needs to be driven intermittently in synchronization with the intermittent movement of the rotary table 1.

As specifically explained in the above embodiment,
The bottle labeling method of the present invention involves pressing a solid adhesive having approximately the same front shape as the label onto the front label of a large number of labels stacked and housed in a magazine by relatively approaching the front label to solidify the front label. The gist is that the label is attached to the glue, and then the label is peeled off from the solid glue and attached to the surface of the bottle,
Labels can be taken out and delivered by pasting them onto a solid adhesive with a front shape that is almost the same as the label, or by peeling it off from there. Unlike the method of applying glue with a roller, there is no risk of excess glue adhering to the label retaining claw or gripping member, and there is no damage caused by drying of the glue when the device is temporarily stopped, making it possible to easily attach labels. The labeling device of the present invention has the effect of being able to take out and deliver the bottle smoothly at all times, and that the label can be reliably affixed to the surface of the bottle. A magazine containing a large number of labels stacked with the back side facing forward is installed around a take-out device with front-shaped solid glue facing outward, and the front label inside the magazine is pasted on the solid glue. In addition, between the take-out device and the bottle conveyance line, the edge of the label attached to the solid glue is grasped and peeled off by a gripping member, and the label is removed by the glue attached to the back side of the label. The gist of the present invention is to provide a sticking device for sticking to the surface of bottles on a conveyance line, and the above method of the invention can be carried out reliably.
