DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is preferably used in a suction holding section of a box packing device for sucking and packing agricultural products, and is particularly suitable for reliably sucking and holding long products such as cucumbers, carrots and eggplants. The present invention relates to an adsorption support for agricultural products.

[0002]

2. Description of the Related Art Conventionally, in a sorting place where agricultural products are sorted, packed, and shipped, a box packing device for automatically packing agricultural products sorted by a sorting device in a box has been widely used as a means instead of humans. This box packing device is provided with a plurality of so-called vacuum suction type suction disks which collectively collect a predetermined number of agricultural products at the same time. The suction cup is 7, is known that is formed in a bellows or cup-shaped soft rubber is generally used as shown in FIG.

By the way, in order for agricultural products having complicated irregularities on the surface to be sucked and infinite changes in their outer shapes to be sucked and held in the same manner by suction disks of the same specifications,
The thickness of the suction plate is made as thin and soft as possible so that it can be in close contact with the surface of the agricultural product that is infinitely varied.

[0004]

However, according to the conventional suction disk, the adhesion to the surface to be sucked is improved, but it is thin and soft, so that the elastic force of the suction disk cannot be maintained depending on the vacuum pressure. There has been a phenomenon in which the shape of the body or the suction opening of the suction disk is displaced inward and the body or the suction opening is closed. (FIG. 9
reference)

[0005] For this reason, the use is limited to those that do not change much from the size and shape of agricultural products,
It was not always possible to stably adsorb, and repeated adsorption mistakes.

[0006] Therefore, in the fruit sorting place, there is still a problem that a manual assisting operation is still required at the time of packing the boxes, and the rationalization has not been achieved despite the spread of the box packing apparatus.

[0007] The problem to be solved by the present invention is that the adsorption can be reliably performed without being affected by various properties (size, shape, etc.) of the agricultural product, and the adsorption center between the adsorption holding body and the agricultural product can be adjusted. It is an object of the present invention to provide an agricultural product adsorption holding body that can reliably adsorb even if it is slightly displaced.

[0008]

In order to solve the above problems, the agricultural product suction holding body according to the first aspect of the present invention is a suction holding body that vacuum-adsorbs agricultural products by bringing the tip of the suction opening into close contact with the surface to be sucked. And the suction opening and a plurality of steps in a long cylindrical shape.
Inwardly of the upper body of the suction opening of the suction mainly formed of flexible rubber and a body portion formed of a bellows, so that the shape of the suction opening and the body portion is not collapsed inwardly Abbreviation to hold
It is provided with a reinforcing member formed in a rectangular ring shape .

[0009]

With the agricultural product holding holder according to claim 1 constructed as described above, when the tip of the suction opening is brought into close contact with the surface to which the agricultural product is adsorbed and sucked, the suction opening and the elongated cylindrical shape are formed.
The inside of the suction main body made of flexible rubber and having a body portion having a plurality of steps of bellows is evacuated, and the agricultural suction is held in close contact with the suction opening by the vacuum suction force. At the time of this holding, by a reinforcing material which is formed in a substantially square annular shape and is mounted inside the body above the suction opening of the suction main body ,
The shape of the suction opening and the body does not collapse inward.
Not be closed because it is urchin retained. Therefore, even agricultural products having irregularities on the surface to be sucked and having various sizes (weights) can be reliably sucked.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

[0011] The agricultural product of the embodiment uses cucumber S.

Numeral 1 is a suction main body having a body portion formed in a bellows shape which is elongated and vertically expandable and contractible in the vertical direction, and is processed into a predetermined shape by molding or the like using a flexible rubber member. . Adsorption body 1 of FIG example is in the bellows 3-step form, the number of stages is not limited. The body of the suction main body 1 of the embodiment is formed in a long cylindrical shape in conformity with the shape of the cucumber S.

Reference numeral 2 denotes an intake port formed on the upper portion of the main body 1 for adsorption. The suction port 2 is connected to a holder 3 having an air intake passage, and the holder 3 is used to suspend the suction main body 1. An intake pipe 5 is connected to the holder 3 via a pipe unit 4. The intake pipe 5 is connected to a vacuum generator (not shown).

Reference numeral 6 denotes a suction opening formed in the lower part of the suction main body 1, and the suction opening 6 holds the cucumbers S. The suction opening 6 has an oval opening 61.
And a lip edge portion 62 having a small thickness on the outer peripheral edge thereof.

Reference numeral 7 denotes a reinforcing member, which is formed of a thin rod of a lightweight bus member, and is formed in a substantially square ring shape following the shape of the suction opening 6 and the body so as to maintain the shape. The reinforcing member 7 is mounted inside a step (lowest step) closest to the suction opening 6 of the three-step bellows of the body of the suction main body 1 . In this embodiment, the reinforcing member 7 is formed in a ring shape by bending a spring member into a predetermined shape (substantially square shape). However , the present invention is not limited to this . For example, a lightweight thin plate material (a non- (Shown) may be formed in a substantially square shape.

The reinforcing member 7 can be fitted integrally when the suction main body 1 is processed by molding.

The suction main body 1 is configured such that its opening 61 is oval in accordance with the long shape of the cucumber S.
It is preferable to set appropriately according to the type of agricultural product.

The operation of the suction holding member having the above configuration will be described.

When the suction opening 6 of the suction main body 1 is brought close to the suction surface of the cucumber S so as to come into contact with the surface of the cucumber S, the lip edge 62 of the suction opening 6 is attracted by the bellows of the suction main body 1. The cucumber S is pressed softly against the surface and adheres to the surface to which the cucumber S is adsorbed. Then, when the inside of the suction main body 1 is evacuated, the cucumber S is sucked into the opening 61 by the vacuum suction force.
(See FIGS. 5 and 6)

As best shown in FIG.
Definitive suction opening 6 of the suction body 1 and when sucked into
The body is held by the reinforcing member 7 so that its shape is not deformed inward, so that the suction opening 6 and the body are not closed. Therefore, the cucumber S closely held by the suction opening 6 is securely held.
