Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a glass bottle gripper suitable for bulk stacking, which is used for simultaneously transferring a large number of glass bottles closely packed in a staggered manner.

(Prior Art) When carrying out bulk packaging, it is necessary to simultaneously grip a large number of glass bottles zigzag on a conveyor or the like with a gripper and transfer them onto a pallet or the like. For this reason, conventionally, as shown in FIG. 5, scissor-shaped scissor grips (11) are arranged directly above the glass bottles in each row, and the protrusions (12) at the inner lower end thereof are engaged with the bottle mouth portions. The idea was to lift the glass bottle. However, since such a conventional scissor grip (11) needs to be lowered between the glass bottles with its lower end opened, the gap (row gap) between the mouth portions of adjacent glass bottles must be 15 mm or more. It was impossible to grip a glass bottle with a row gap smaller than this.

On the other hand, for example, as shown in Japanese Utility Model Publication No. 63-11449,
A gripper that expands the claw plate by expanding it by air pressure is also proposed, but in this case, the claw plate is inserted into the hole of the object to be transferred, so it cannot be applied to a small diameter glass bottle. Moreover, one gripper can only hold one transferred object and cannot transfer a large number of glass bottles at the same time.

(Problems to be solved by the invention) The present invention solves the above-mentioned conventional problems and provides a glass bottle gripper that can transfer glass bottles by a gripper even when the row gap is about 8 mm. It was made to provide.

(Means for Solving the Problems) The present invention made to solve the above problems is such that the lower end portions are supported so as to be in contact with each other and are inserted between the rows of the glass bottles in a state where no external force is applied. A unit formed by expanding air between the claw plates by air pressure to push and spread these claw plates outward, and further, installing an expansion body for engaging the engaging part of the claw plates with the outside of the bottle mouth part. It is characterized in that many columns are arranged in parallel.

(Embodiment) Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment.

In FIGS. 1 to 4, (1) is a large number of glass bottles that are in a zigzag and dense state, and (2) is the bottle mouth. The glass bottle gripper of the present invention is composed of elongated units having the same structure and arranged in parallel in a plurality of rows corresponding to the centers of the row gaps.
Only two sets of units are shown in FIGS.

Each unit is provided with an elastic body (3) made of anti-vibration rubber or the like arranged at predetermined intervals, and two claw plates (4) and (4) upper end portions are provided on both sides of each elastic body (3). Is installed. These claw plates (4), (4) are preferably made of a metal plate, and their lower ends are in contact with each other when they are not subjected to an external force, as shown in FIG. Further, a rubber plate or the like is attached to the outer surfaces of the lower end portions of the claw plates (4) and (4) to form a bottle mouth portion (2) and an engaging portion (5). 2 supported by the elastic body (3) in this way
An inflatable body (6) capable of being inflated by air pressure is attached to the inside of the upper portions of the claw plates (4) and (4). The expander (6) is an elongated and flat tube, and when compressed air is supplied from the air inlet (7) to the inside, the expander expands from the state shown in FIG. 2 to the state shown in FIG.
The claw plates (4), (4) can be spread outwardly against the elastic force of the elastic body (3).

In addition, (8) and (9) are inverted U-shaped press fittings that are mounted above the claw plates (4) and (4) at appropriate intervals, and the stud bolts (10) attached to these units make the unit. Supports the whole.

(Operation) As shown in FIG. 2, the glass bottle gripper of the present invention constructed as described above has two claw plates (4), () between rows of glass bottles (1) densely arranged in a staggered manner. If the lower end of 4) is inserted and the engaging part (5) is positioned slightly below the bottle mouth (2) of the glass bottle (1) and air pressure is introduced into the expander (6), (4) and (4) are expanded outward by the expander (6) as shown in FIG. Similarly, in the adjacent unit, the claw plates (4), (4) are also outwardly pushed and expanded, so that the bottle mouth (2) of the glass bottle (1) has these claw plates (4), (2) from both sides. 4) engaging portion (5),
It is sandwiched by (5) and gripped. Therefore, the entire glass bottle (1) can be lifted at the same time and the glass bottle (1) can be simultaneously lifted and transferred onto a pallet or the like for bulk packaging. When the glass bottle (1) is released, the air pressure inside the expansion body (6) is simply released, and the claw plates (4) and (4) are made to contract with the elastic body (3) as the expansion body (6) contracts. 2) is returned to the state of FIG. 2 and the engaging portion (5) can be disengaged from the bottle mouth portion (2).

As described above, the claw plates (4) and (4) of the present invention are inserted between the glass bottles (1) with their lower end portions in contact with each other, so that the zigzag glass bottles (densely arranged in a zigzag pattern) ( It is sufficient if the row gap of 1) is only about 8 mm. Moreover, since the opening / closing operation can be performed by the expander (6), the thickness of each unit itself can be made sufficiently thin. As a result, according to the glass bottle gripper of the present invention, it is extremely easy and reliable to grip even a small glass bottle with a small diameter and a small difference between the diameter of the bottle and the diameter of the bottle with a small row gap. It becomes possible to transfer it.

(Effects of the Invention) As described above, the present invention utilizes a large number of units having expansion bodies between two claw plates to simultaneously grip a large number of staggered glass bottles. It can be transferred and can be used even when the row gap is about 8 mm. Therefore, according to the present invention, it is possible to bulk-package a small glass bottle which could not be conventionally bulk-packaged.

Therefore, the present invention has an extremely great practical value as a glass bottle gripper that eliminates the conventional problems.
