Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a bottle label removal device.

BACKGROUND ART Conventionally, as shown in FIG. 3, a device for continuously removing labels from bottles has been used, as shown in FIG. In this state, the cleaning liquid 3 is immersed in the water from the spray nozzle 33.
There is a device that removes the label by squirting 2, but since the label peeled off from bottle X floats in the cleaning liquid 32, a strainer (not shown)
was removed by filtration.

Problems to be Solved by the Invention However, with this type of bottle label removing device, the labels become fine in the cleaning liquid 32, and the strainer and injection nozzle 33 may be clogged.

The present invention solves the above-mentioned problems, and aims to provide a bottle label removal device that can efficiently remove a bottle label without immersing the bottle in a cleaning liquid.

Means for Solving the Problems In order to solve the above problems, the present invention has a bottle stand that holds the bottom of the bottle and moves in a predetermined direction while rotating, and a bottle stand that moves in synchronization with the bottle stand and moves over a predetermined interval. A bottle spout holder rotatably holds the bottle spout, and a plurality of bottles are arranged along the movement direction of the bottle stand in the predetermined section, each of which sprays high-pressure jet water to a different height to remove the bottle label. It is equipped with an injection nozzle.

Effect With the above configuration, the bottle is rotated and moved in a predetermined direction while being held by the bottle stand and bottle holder.
During this movement, the label on the bottle is removed by high-pressure jet water sprayed from each spray nozzle. In this case, since the bottle moves while rotating, there is no need to align the label on the bottle in a predetermined direction, and since the multiple injection nozzles are each oriented at different heights, the label on the bottle can be easily affixed. Even if the height of the label is not constant, the high-pressure jet water from one of the spray nozzles will remove the label.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

1 and 2 are a plan view and a sectional view of a main part of a bottle label removing device. Figures 1 and 2
In the figure, reference numeral 1 denotes a disc-shaped rotary table that rotates in the A direction to move the bottle X in order to remove the label Y of the bottle X. On the upstream side of the rotary table 1 in the bottle movement direction, there is a timing screw. A supply side star wheel 3 is disposed for feeding the bottle X, which has been moved by 2, toward the rotating table 1 while rotating in the B direction. A discharge side star wheel 4 that rotates and sends out the bottle X is provided. 5 is a guide for the star wheels 3, 4 on the supply side and the discharge side.

The rotary table 1 is rotated by a motor 6 disposed below the rotary table 1 through a gear 7 attached to the motor 6 and a turning ring 8 attached to the lower surface of the rotary table 1 so as to mesh with the gear 7. Rotated in direction A. Although not shown, the timing screw 2 and star wheels 3 and 4 on the supply side and the discharge side are also driven by this motor 6. A plurality of bottle stands 9 on which bottles X are placed are rotatably arranged at predetermined intervals on the outer circumferential side of the turntable 1. A rubber plate is attached to the top surface of the bottle stand 9 to bring it into close contact with the bottom of the bottle, and a roller 10 made of resin or rubber is provided at the bottom of the bottle stand 9. The roller 10 of the bottle stand 9 comes into contact with the fixed cam 12 provided in the section from the downstream side of the supply side star wheel 3 to the discharge side star wheel 4 in the frame 11 installed so as to surround the bottle stand 9. rotates in the D direction. An upper disk 14 is fixed to the rotary table 1 via its central axis 13,
A plurality of bottle spout holders 15 are attached to the upper disk 14 at positions facing the bottle stand 9. The bottle mouth holder 15 includes an upper holding member 16 attached to the upper disk 14 and extending downward from the outside of the upper disk 14, and a lower holding member 18 attached to the upper holding member 16 via a spring 17. The holding member 17 has a holder member 19 which is rotatably attached to the lower end of the holding member 17 and expands downward to open. They work together to hold the bottle. Figures 1 and 2
As shown by the imaginary line in the figure, a cam 20 is provided on the outer circumferential upper surface of the upper disk 14 between the downstream side of the discharge side star foil 4 and the supply side star foil 3, and a roller 2 is attached to the upper holding member 16.
1 comes into contact with the cam 20, the bottle mouth holder 15 rises, and the holding of the bottle X is released. Further, a plurality of injection nozzles 22 for ejecting high-pressure jet water toward the side of the bottle X are arranged above the frame 11 from the downstream side of the supply side star wheel 3 to the discharge side star wheel 4. These injection nozzles 2
The injection angles of the two injection nozzles 22 can be changed, and the respective injection nozzles 22 are oriented at different heights of the bottle X. Reference numeral 23 denotes a drain cover erected on the rotary table 1.

In the above configuration, the bottle X sent by the timing screw 2 is carried along the guide 5 by the supply star wheel 3 and placed on the bottle stand 9. At this time, the bottle spout holder 15 is lowered by the separation of the roller 21 provided on the top from the cam 20, and the bottle X is moved between the bottle spout holder 15 and the bottle base 9.
The bottle is moved in the A direction while being rotated by contact between the roller 10 of the bottle stand 9 and the fixed cam 12 while being held between the top and bottom. Then, the label Y of the bottle X is peeled off by high-pressure jet water jetted from the jet nozzle 22 provided at a location on the way. In this case, since bottle X is rotated in direction D,
There is no need to align the orientation of the labels in advance, and the high-pressure jet water is jetted at different heights, so even if the positions of the labels Y on the bottle X are slightly different, all the labels Y are reliably removed. The bottle X from which the label Y has been removed is moved to the discharge side star foil 4, and when it is held by the discharge side star foil 4, the bottle opening foil 15 has its roller 21 moved toward the cam 2.
0 and is lifted up and away from the bottle mouth. Thereafter, the bottle X is discharged downstream by the discharge side star foil 4.

Effects of the invention As described above, according to the invention, the label on the bottle can be removed in a short time by the high-pressure jet water jetted from the jet nozzle. In this case, since the bottles are rotated by the bottle stand, there is no need to align the labels on the bottles in advance, and the injection nozzles are oriented at different heights, so even if there are many different types of bottles and labels, there is no need to align them. The label can be reliably peeled off without being overlaid, thereby providing a bottle label removal device that can effectively perform label removal work.
