Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an apparatus for adsorbing and conveying fruits, and can be used in an automatic fruit packing machine, a fruit sorting plant, and the like.

[Problems to be solved by conventional techniques and devices]

Conventionally, a form in which a plurality of fruits are aligned, adsorbed at once, and packed in a storage box such as a cardboard box that stands by on the side is known as described in, for example, JP-A-63-44425.

In addition, there is also a mode in which the adsorbents at the ends of the adsorbents formed in a plurality of lines are flipped up to make them inactive in order to change the number of fruits to be adsorbed (for example, Japanese Patent Publication No. 48383/1988).

[Problems to be solved by the device]

By the way, for example, the size of a cardboard box that stores fruits is set to a specified size, but the fruits such as persimmons, pears, and apples that are to be stored in the cardboard box are sorted according to size, while the above cardboard boxes are placed. When storing, it is packed so that there is no room in the storage box, and it is desirable to change the arrangement method for each class and respond appropriately.

However, in the latter embodiment, the adsorbent at the end is flipped up to bring it into a non-acting state, which complicates the configuration and tends to cause trouble when descending into a deep storage box depending on the flipping up state.

[Means for Solving the Problems]

In order to solve the above-mentioned drawbacks, the present invention aims to eliminate the above-mentioned drawbacks, and fruit alignment positions (a) in which a plurality of rows of alignment supply lines (c) are provided along the direction in which the fruits 1 of which the sizes are selected and transferred are conveyed by the conveyor 2 are provided. And a box conveyor 3 parallel to the conveyor 2

In the apparatus for adsorbing and transporting fruits, which is provided with an adsorbent 6 for integrally adsorbing fruits, the conveyor 2 is provided with a number-of-rows changing means 33 for changing the number of rows for receiving transferred fruits, and is attached to the carrier 5. A turning means for changing the posture of the aligned supply line (c) between the base 26 and the adsorbent 6 in the vertical and horizontal directions.
30 and provided, based on the setting change of the predetermined number to be accommodated,
The fruit adsorption transporting device is configured to output the above-mentioned number-of-rows changing command signal and a control unit 31 for outputting a turning command to the turning means 30 while the carrier 5 is moving.

[Operation and effect of device]

The fruits 1 selected and sized are transferred on the conveyor 2 and aligned on a plurality of lines of supply lines at the fruit alignment position (a). On the other hand, an empty storage box 4 on the box conveyor 3
Waits in the box waiting position (b). The carrier 5 packs the aligned fruits adsorbed by the adsorbent 6 into the storage box 4 while moving between the fruit alignment position (a) and the box standby position (b). That is, according to the size of the number to be accommodated, the control unit 31 changes the number of threads changing means to the set number of threads, and the adsorbent 6 after adsorption has a constant posture with a turning or non-turning signal output to the turning means. The fruit can be stored in substantially the entire storage box 4 waiting at.

Therefore, it is possible to use the storage box 4 having a prescribed shape for fruits of different sizes.

Also, the setting of different fruit storage patterns depends on whether or not the adsorbing body 6 turns around the mounting base 26 of the carrier 5, so that the configuration can be simplified as compared with the conventional configuration described above.
