The respective eggplants A sucked by the respective suction pads 15... are received together into the bag P and suction is canceled, thereby completing casing of the eggplants A for a stage.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, a fruit vegetable used for box-packing a fruit vegetable such as eggplant, cucumber, persimmon, tomato, apple and mandarin in a box formed of corrugated cardboard or synthetic resin. Relating to boxing equipment.

[0002]

2. Description of the Related Art Conventionally, as a device for packing the above-mentioned fruits and vegetables, for example, a suction pad connected to each adsorption pad by adhering each adsorption pad to an appropriate number of each fruits and vegetables selected according to their ranks. Adsorbed and held by the negative pressure of the blower. Move each fruit and vegetables adsorbed and held by each suction pad to the upper part of the cardboard box supplied to the boxing position, and collectively store each fruit and vegetables adsorbed and held by each suction pad in the packaging bag laid inside the cardboard box. There is a device that shuts off or stops the negative pressure of a suction blower connected to a suction pad, and sequentially packs an appropriate number of fruit vegetables in a corrugated cardboard box.

[0003]

However, when cucumbers such as those in the above example are packed in a box, since the skin of each cucumber adsorbed and held by each suction pad has many protrusions and wrinkles, Even if the cucumbers adsorbed and held and the packaging bag laid inside the cardboard box contact each other, the surface resistance generated at the contact area between the packaging bag and each cucumber is small, making it easy to pack an appropriate number of cucumbers in a box. However, for example, when packaging eggplants with a soft epidermis and a smooth surface, due to the characteristics of the eggplant itself, the packaging bag laid inside the cardboard box and each cucumber adsorbed and held by each adsorption pad can easily adhere to each other. Since the surface resistance generated at the contact portion between the bag and each eggplant is larger than the suction force of each suction pad, the box packing work cannot be performed smoothly. Also, if you try to forcefully pack an appropriate number of each aubergine against its contact resistance, some aubergines will fall out of each adsorption pad, or the adsorption posture of each aubergine will be displaced, so an appropriate number However, there is a problem that it is difficult to pack the eggplants in a box in an aligned state.

In view of the above problems, the present invention reduces the surface resistance generated at the mutual contact portions by spraying a liquid on the opposing surfaces of a box body formed in an open upper surface and each fruit and vegetable, so that an appropriate number of them can be obtained. An object of the present invention is to provide a fruit and vegetable boxing device that can surely and easily carry out the work of boxing each fruit and vegetable.

[0005]

According to the first aspect of the present invention,
The present invention is characterized in that it is a fruit and vegetable box packing device provided with a liquid spraying means for spraying a liquid against the facing surfaces of the box body and the fruit and vegetables when the appropriate number of each of the fruit and vegetables is boxed.

According to a second aspect of the present invention, in addition to the structure of the first aspect, a liquid spraying means for spraying a liquid at the boxing position against the inner peripheral surface of the box body facing the fruit and vegetables. It is characterized by being a fruit and vegetable box packing device provided with.

According to a third aspect of the present invention, in addition to the structure of the first aspect, liquid spraying means for spraying a liquid onto the outer peripheral surface of the fruit and vegetables which is in contact with the box body is provided at the boxing position. It is characterized in that it is a provided fruit and vegetables box packing device.

According to a fourth aspect of the present invention, in addition to the configuration of the first aspect, a fruit sprayer is provided in the preceding stage of the boxing position, which is provided with liquid spraying means for spraying a liquid onto the inner peripheral surface of the box body. It is characterized by being a box packing device.

[0009]

According to another aspect of the present invention, there is provided a fruit and vegetable boxing device, wherein liquid spraying means is driven to face the box body supplied to the boxing position with the fruit and vegetables held by the boxing means, for example, tap water. , Spraying distilled water, vegetable oil, alcohol and other liquids,
A liquid thin film is formed on the contact part between the box and each fruit and vegetable.
Then, by packing an appropriate number of each fruit and vegetables held by the box packing means inside the box, the friction coefficient generated at the contact portion between the box and each fruit and vegetables is reduced, and mutual contact movement is smooth. Therefore, it is possible to box an appropriate number of fruit vegetables in a state of being aligned in parallel.

In addition to the operation of the above-mentioned claim 1, the fruit-vegetable box-packing device according to claim 2 drives the liquid spraying means to spray the liquid onto the inner peripheral surface of the box body supplied to the packing position. After that, by packing each fruit and vegetables held by the boxing means inside the box, the contact resistance between the box and each fruit and vegetables becomes small, and the boxing work can be performed easily.

In addition to the function of claim 1, the fruit and vegetable box packing device according to claim 3 drives the liquid spraying means to spray the liquid onto the outer peripheral surface of each fruit and vegetables held by the box packing means. By packing the box inside the box body afterwards, the contact resistance between the box body and each fruit and vegetables becomes small, and the box packing work can be performed easily.

According to a fourth aspect of the present invention, in addition to the operation of the first aspect, the vegetable box packaging device drives the liquid spraying means to spray the liquid on the inner peripheral surface of the box body having the open upper surface. By supplying to the boxing position after attaching, and by boxing each fruit and vegetables held by the boxing means inside the box, the liquid spraying work and the boxing work can be performed continuously, and the box and each fruit and vegetables The contact resistance is small and the boxing work can be done easily.

[0013]

According to the present invention, liquids such as tap water, distilled water, vegetable oil, alcohol, etc. are sprayed on the facing surfaces of the box body formed in the open upper surface and the respective fruits and vegetables before packaging. Therefore, the friction coefficient generated at the contact portion between the box and each fruit and vegetable becomes small, and the mutual contact movement becomes smooth, so that the work of packing an appropriate number of each fruit and vegetable can be carried out smoothly. Further, even when the inner peripheral surface of the box body and the outer peripheral surface of each fruit and vegetables contact each other at the time of boxing, the surface resistance generated at the mutual contact portions is smaller than the holding force of the boxing means. As such, each eggplant is removed from each suction pad, or the adsorption posture of each eggplant is not displaced, and an appropriate number of each vegetable can be boxed in a state of being aligned in parallel, and the boxing operation is reliable and Easy to do.
