Description

[Detailed description of the device] "Industrial application field" This device is for the packaging of foods, etc., especially a plurality of chicken eggs. The present invention relates to a suction cup of a peeling device that sucks and peels one by one from a pack and drops it on a lower conveyor or the like.

"Prior Art" For example, in a sucker of a pack peeling device provided in an egg packaging device, a suction port of a flexible body such as rubber is fixed to a mounting base connected to a vacuum pump. The mouthpiece is adapted to rotate up and down together with the mount.

On the other hand, the pack has a plurality of egg storage lobes projecting downward. Then, of the many packs stacked in the hopper, the suction port adsorbs to one storage seat of the lowest pack and rotates downward, whereby the packs are separated one by one, Is dropped onto the conveyor.

"Problems to be solved by the invention" However, the size of the egg packaging pack is not constant depending on the size of the eggs to be packaged or the packaging of the same size egg depending on the manufacturer.

Therefore, when the pack in the hopper is replaced with a pack having a different size, the core of the suction port and the core of the accommodating seat are deviated from each other, and a suction error occurs. In order to prevent this suction error, there has been an inconvenience that the suction port and the pack must be aligned each time the pack is replaced.

"Means for Solving Problems" This invention is intended to eliminate the inconvenience of centering the suction port and the pack, which is required every time the pack is replaced. The summary will be given.

A movable table having a fixed suction port is provided on a mounting table connected to a vacuum pump so as to be movable orthogonal to the core of the suction port. Then, a pressing means such as a spring is provided for bringing the movable table and the mounting table into pressure contact with each other.

"Operation" The accommodating seat of a pack in which a large number of sheets are stacked has considerable rigidity. Therefore, the suction port rotated upward to remove the pack has a suction port so that when the core of the pack is displaced from the core of the suction port, the core of the pack and the core of the suction port are aligned when the suction port contacts the accommodation seat. As it moves upward, the movable table moves in the direction orthogonal to the core of the suction port, that is, in the lateral direction, against the pressing force of the pressing means.

When the suction port is sucking the accommodation seat, the movable table does not move due to the vacuum pressure in the suction port, so that the position of the suction port is maintained.

Next, when the sucker pivots downward and releases the pack, the moving base and the mounting base are pressed against each other by the pressing means, the moving base does not move, and the core and the sucker of the pack are peeled in the subsequent peeling. The cores of the packs coincide with each other, and the pack can be adsorbed without any trouble.

"Embodiment" The present invention will be described in detail based on an embodiment shown in the drawings.

Reference numeral 1 is a suction cup, which is a mounting base 2, a moving base 4, a connecting ring 10, a pressing means.
Mainly composed of 15.

Reference numeral 2 is a mount, and a rotating arm 21 connected to a vacuum pump (not shown) is screwed to the lower part. The rotating arm 21 rotates in the vertical direction as a part of the unillustrated pack peeling device. Three
Is a connecting ring fixing seat recessed in the upper end of the mounting base 2.

Reference numeral 4 denotes a movable table, which is provided with a circumferential outer groove 5 which is open to the outside in a lower portion, and a flange 6 is formed below the outer groove 5. Further, the upper portion of the outer groove 5 projects outward, the upper surface forms the suction port fixing seat 7, and the lower surface forms the spring receiving seat 8.

A suction port 9 is made of rubber or other flexible material and is fixed to the suction port fixing seat 7 of the movable table 4.

Reference numeral 10 denotes a connecting ring, which is formed in a U-shaped ring shape whose cross section opens inward, and an upper inner edge 11 protruding inward is loosely fitted in the outer groove 5. Also, the lower inner edge 12 protruding inward
Are fixed to the connecting ring fixing seat 3. Upper and lower inner edges
The outer edge connecting 11 and 12 forms a stopper 13. The flange 6 is formed in the inner groove 14 formed in the opening of the connecting ring 10.
Is movably embedded. Stopper 13 is movable table 4
When moves too much, the collar 6 abuts and blocks the movement.

Here, the distance 1 between the outer surface of the collar 6 and the inner surface of the stopper 13
Is a pack having a different size from the core A of the mouthpiece 9
It is preferable to set it to be equal to or slightly larger than the maximum value of the deviation l2 of the accommodating seat 32 of 31 from the core B.

Reference numeral 15 is a compression coil spring, which constitutes a pressing means. This coil spring 15 is used for the spring seat 8 of the movable table 4.
And the upper surface of the upper inner edge 11 of the connecting ring 10. Therefore, since the connecting ring 10 is fixed to the mounting base 2,
The coil spring 15 presses the moving table 4 upward, and the upper surface of the collar 6 of the moving table 4 is constantly pressed against the lower surface of the upper inner edge portion 11 of the connecting ring 10.

Therefore, as shown in FIG. 1, when the suction port 9 is rotated upward to adsorb the accommodation seat 32 of the pack 31, the core A of the suction port 9 and the accommodation seat 32 are rotated.
When the core B of 32 is displaced, the accommodating seats 32 are stacked.
Is hard, the mouthpiece 9 is pushed in the direction of arrow a. Therefore,
The moving seat 4 moves in the same direction against the pressing force of the coil spring 15, and the two cores A and B are aligned as shown in FIG.

When the suction pump 1 is evacuated by the vacuum pump, the moving seat 4 does not move due to the vacuum pressure. When the peeled pack 31 is released, the vacuum seat does not work, but the pressing force of the coil spring 15 does not change the position of the moving seat 4, so that the cores need not be aligned for the next peeling.

Incidentally, without providing the coil spring 15 as the pressing means,
It is possible to provide magnets on the upper surface of the collar 6 and the lower surface of the upper inner edge portion 11 so as to face each other, or to provide magnets on the lower surface of the collar 6 and the upper surface of the lower inner edge portion 12 so as to face each other.
In these cases, the opposing magnets may be either attractive or repulsive.

It is also possible to mount the movable table 4 on the upper surface of the mounting table 2 without providing the connecting ring 10 and provide magnets for attracting each other on the upper surface of the mounting table 2 and the lower surface of the movable table 4. . In this case, a ring-shaped stopper can be erected on the outer edge of the upper surface of the mounting base 2 or a ring-shaped stopper can be hung on the lower edge of the moving base 4.

[Effect] When the core of the mouthpiece and the core of the pack do not match, the movable stand moves and the two cores coincide with each other due to the upward rotation of the mouthpiece, so the core of the mouthpiece and the core of the pack are replaced each time the pack is replaced. It is extremely convenient because there is no need to make adjustments.
