Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long object boxing device used for boxing long objects such as cucumber, carrot, potato, and eggplant.

[0002]

2. Description of the Related Art Conventionally, as a method for packing cucumbers as in the above-mentioned example, for example, after arranging an appropriate number of cucumbers sorted in equal rank in parallel, a synthetic rubber is placed on the upper peripheral surface of each cucumber. When the suction pads made of the same are brought into close contact with each other, they are suction-held by negative pressure of the suction blower. Next, there is a method in which when a suitable number of cucumbers adsorbed and held by the respective suction pads are collectively stored in a cardboard box, the negative pressure of the suction blower is shut off or stopped, and an appropriate number of cucumbers is packed in the box.

[0003]

However, when the appropriate number of each cucumber is adsorbed and held by each adsorption pad as described above,
It is difficult to closely attach each suction pad to the upper peripheral surface of each cucumber, and the air is sucked through the gap formed on the suction surface of each suction pad. Negative pressure cannot be secured. and,
The suction surface of each suction pad does not follow the deformation of the top surface of each cucumber, and the negative pressure by the suction blower decreases, which makes the suction position and posture unstable, making it possible to secure an appropriate number of each cucumber. It has a problem that it is difficult to adsorb and hold it.

In view of the above problems, according to the present invention, since the locking hooks are respectively locked to the front and rear end portions of each long object placed on the long object placing section to maintain the horizontal position, An object of the present invention is to provide a long object boxing device capable of stabilizing the holding posture of the object, performing the operation of boxing a long object quickly and reliably, and saving the work and improving the efficiency.

[0005]

The invention according to claim 1 is
The hook insertion portion is formed on the front and rear portions on the upper surface side of the long object mounting portion so as to face the front and rear end portions of each long object mounted on the long object mounting portion. At the upper position facing each hook insertion portion of the mounting portion, each locking hook formed so that it can be inserted between the long objects placed on the long object mounting portion is provided, and A long object provided with hook locking means for inserting the respective locking hooks between the long objects projecting to the hook insertion portion side and locking the respective locking hooks to the front and rear end portions of the respective long objects. It is a box packing device.

According to a second aspect of the present invention, each of the upper and lower portions of the long object placing portion is formed so that it can be inserted into each of the long objects placed on the long object placing portion. Provide a locking hook,
Provided at a lower position of the long object placing portion is a lifting means for lifting each long object placed on the long object placing portion to an appropriate height at which the locking hooks are locked, A long object provided with hook locking means for inserting the respective locking hooks between the long objects lifted by the lifting means and locking the respective locking hooks to the front and rear ends of the long objects. It is a box packing device.

[0007]

According to the first aspect of the present invention, the hook locking means is driven to insert the respective locking hooks between the long objects protruding toward the respective hook insertion portions of the long object mounting portion, After locking each locking hook at the front and rear ends of each long object and holding it in a horizontal posture, the appropriate number of each long object held by each locking hook is packed inside the box, The long box packing work can be done reliably.

According to the second aspect of the present invention, the lifting means is driven to lift each long object placed on the long object placing section to an appropriate height. At the same time, by driving the hook locking means, the locking hooks are respectively inserted between the long objects lifted to an appropriate height, and the respective locking hooks are locked at the front and rear ends of the long objects. After holding it in a horizontal position, the appropriate number of long objects held by the locking hooks are packed inside the box body. The locking work of each locking hook can be performed more easily than inserting and locking the locking hooks.

[0009]

According to the present invention, the locking hooks are respectively locked to the front and rear ends of the long objects protruding toward the hook insertion portions of the long object mounting portion to hold them in a horizontal posture. Therefore, it is possible to prevent each cucumber from being adsorbed and held as in the conventional method, and to prevent each cucumber from falling off in the middle of the process. Can be done reliably. Moreover, since an appropriate number of long objects are collectively held and packed in a box, the labor and work of manually packing a large number of long objects one by one can be saved, and the time required for the boxing work can be shortened. It is possible to save labor and improve efficiency.

Further, by locking the respective locking hooks to the front and rear ends of the long objects which are appropriately raised, and holding them in a horizontal posture, the long objects are placed between the long objects placed in parallel. Rather than inserting and locking the respective locking hooks, the locking work by the respective locking hooks can be performed easily, and the workability in packing the boxes is improved.
