Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a fruit packaging device, and can be used in fruit packaging and shipping plants, fruit sorting plants, and the like.

BACKGROUND OF THE INVENTION Conventionally, so-called material handling equipment has been common, which picks up a plurality of articles such as equipment, moves them to a storage box, and lowers them into boxes.

In addition, a method for integrally adsorbing and moving fruits in a lined state with a carrier provided with an adsorbent and storing them in a storage box at a packing position is disclosed in Japanese Patent Application Laid-Open No. 61-20331, for example.
There are known examples such as Publication No. 7.

Problem to be Solved As shown in the above-mentioned Japanese Patent Application Laid-Open No. 61-203317, after packing fruits in an array into a tray bag which is a cushioning material that receives the fruits from below, the tray bag containing the fruits is transferred. If the fruit is stored in a storage box, a device that performs the packing operation twice is required, and the device for holding and transporting the fruit pack becomes complicated, which is a problem to be solved.

Means for Solving the Problems The present invention provides a carrier (3) having a plurality of fruit adsorbents (2) capable of adsorbing and holding fruits (1) and moving between predetermined positions R(a)(0). A descending moving layer (5) that integrally attracts and moves a plurality of fruits (1) arranged at the predetermined position M (a) and descends to the fruit storage box (4) at the predetermined position (b). , characterized in that it is provided with a sending device (7) that sends out a cushioning material (6) that receives and buffers each descending fruit (1) from below and releasably locks it on the downwardly moving layer (5). The structure of the fruit packaging device is as follows.

Effects of the Invention The cushioning material (6) fed out from the side by the feeding device (7) may be a sheet of corrugated paper or the like, and the fruit (1) arranged in a boxed position and lowered by the carrier (3). This cushioning material (6) may be a tray pack arranged to form a saucer-like recess according to the arrangement posture of the carrier (3).
5) The fruit (1) is fed out to the place where it is held and held.
The carrier (3) that has absorbed the fruit (3) descends and picks up each fruit (
1) pushes down the cushioning material (6) from above.

In the case of a tray bag, when each fruit (1) falls further down while fitting into the saucer-shaped recess, the cushioning material (6) is released and pushed through the upper opening of the storage box (4) until it reaches a predetermined position. When descending, the adsorption of the adsorbent (2) is released and the carrier (3) rises, moves again to the predetermined position (a), and then moves to the next descending moving layer (5). The next buffer material (6) is moved by the device (7) to the downwardly moving layer (5).
) into the specified position. If the cushioning material (6) is a sheet of corrugated paper, when the lock is released at the speed of the descending fruit, it will be at a position at a height such that it will fit within the upper edge of the storage box (4) in a short time. The cushioning material (6) is pushed down in a horizontal position by pressing down on the lower surface of each fruit (1) while lightly rubbing against the inner circumferential wall of the storage box (4) by the downward force of the carrier (3). It can be stored in the same way as a pack.

Effects of the Invention With the above-described structural action, there are two types of stuffing device: one that stuffs the fruit (1) into a pack of cushioning material (6), and the other that transports and boxes the pack containing the fruit (1). A heavy stuffing device is not required and the stuffing device for stuffing the fruit (1) into the pack can be omitted.

Also, a carrier (3) is used to pack the fruit (1) into the storage box (4).
) etc., which only adsorbs the fruit (1), can eliminate the need for a device that adsorbs the cushioning material (6) such as a pack, making the suction mechanism simple.

In addition, the feeding device (7) for the cushioning material (6) only needs to be fed in the horizontal direction, and can be made with a simple structure.
The downward force of the carrier (3) can be used to release the carrier (3) from the locking device and to push it into the box.

Therefore, by combining these effects, the fruit (1) and the cushioning material (6) can be packed at the same time with a simplified structure and less power than before.
