Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a process prior to grafting of vegetable seedlings such as cucumber or pumpkin,
These flat seeds are aligned and sown, sowing machines for aligning cotyledons of seedlings in a substantially constant direction, and agricultural products such as cucumber are aligned in a fixed direction after harvesting, and sorting, box packing, food processing, etc. are performed mechanically. The invention relates to an aligning device for various working machines.

[0002]

For example, one of the means for automating the grafting operation is to grip the upper and lower portions of the stems of the rootstock and the seedlings conveyed on the transport line with the gripping hands. There is a grafting means that cuts the middle part of the hand with a cutter and joins the lower stem part of the cut rootstock and the upper stem part of the scion. However, since it is joined (grafted) near the cotyledon development base of the seedling, it is grasped. It is necessary to grasp the cotyledon deployment base with a hand. In this case, depending on the direction of the cotyledons to be developed, it is easy to drop from the gripping hand and lacks stability. In order to align the direction of cotyledons of each seedling, conventionally, in the case of this aligned sowing, the aligned sowing using image processing or the like is performed, but the cost is extremely high and the workability is poor. Therefore, with a simple configuration using a seed shooter and a seeding shutter, a rectangular mouth shape having a long side and a short side of the seed shooter regulates the release posture of the flat seed, and there is also a means for performing this aligned sowing. With only such a mouth shape of the seed shooter, the seed release attitude is not stable and alignment accuracy is poor.

Also, when growing crops such as cucumber are mechanically sorted, packed in a box, or processed for food after harvesting, it is necessary to arrange the postures of the crops in a certain direction in advance. Is time-consuming and inefficient, and when performed mechanically, not only is the system complicated and expensive, but also reliable when the shape of each crop is different. It was lacking in sex.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention comprises a guide member for determining the direction of an object to be aligned, and a mounting member for mounting the object to be aligned on a mounting surface. When aligning the target objects in a certain direction by relative movement, for example, when the transport conveyor of the agricultural product to be the target is used as a mounting member, and when the agricultural products to be mounted on the transport conveyor are moved in a direction orthogonal to the transport direction of the conveyor. The position of the agricultural product is adjusted by the guide member, and it is possible to easily align the agricultural products during the conveyance of the conveyor, and the alignment accuracy is improved by extremely simple means.

[0005] A guide member for dropping and guiding the object to be aligned and a member for placing the object to be aligned for opening and closing the lower end exit of the guide member are provided. The posture of the alignment target discharged from the guide member is aligned in a certain direction by the relative movement with respect to the mounting member, and the posture of the agricultural product to be aligned along the inner wall of the guide member is satisfactorily aligned, and this posture is broken. In this way, it is possible to release the food without maintaining a good posture, improve the accuracy of the alignment posture of the agricultural products, and improve the work efficiency in the post-process.

Further, a seed shooter for feeding seeds from a seed hopper one by one, and a seeding shutter for opening and closing a lower end outlet of the seed shooter, sowing is performed by opening the seeding shutter. In the alignment device of the machine, the opening operation speed of the seeding shutter is slow in the first half,
In the second half of the shooter, the seeds are provided so as to be fast, and in the first half of opening, the flat seeds are stably and satisfactorily aligned with the inner wall of the shooter. ), And in the latter half of the opening time, the seeds are released without rotating while keeping the adjusted posture,
This is to improve the alignment accuracy.

[0007] Furthermore, a seed shooter for feeding seeds from a seed hopper for each grain and a seeding shutter for opening and closing a lower end outlet of the seed shooter are provided, and sowing is performed by opening the seeding shutter. In the seeding machine alignment device, during the opening operation of the seeding shutter, by moving the seeding shutter in one direction on the opening and closing side, and then in the opposite direction,
After that, it is provided so as to be fully opened, for example, at the time of a slight opening operation by moving the shutter in one direction at the beginning of the opening operation, aligning the seeds by contacting the inner wall of the shooter, and moving in the opposite direction to return to closing. Inverted seeds are also turned over,
When the seeds are fully opened thereafter, the seeds are sown at substantially predetermined positions with the directions of the seeds aligned, thereby improving the alignment accuracy of the seeds.

Also, a seed shooter for feeding seeds from a seed hopper one by one, and a seeding shutter for opening and closing a lower end exit of the seed shooter, sowing is performed by opening the seeding shutter. In the aligning device of the machine, so as to change the seeding direction of the seed vertically and horizontally, by providing the outlet shape of the sowing shooter freely deformable, with a simple operation of only deforming the outlet shape of a single shooter, The present invention enables sowing in both vertical and horizontal sowing directions, thereby improving workability.

Further, a seed shooter for feeding seeds from a seed hopper for each grain, and a seeding shutter for opening and closing a lower end outlet of the seed shooter, sowing is performed by opening the seeding shutter. In the aligning device of the machine, the outlet shape of the seeding shooter is provided so as to be deformable in accordance with various seed shapes, causing inconvenience such as catching even when the flat state or the size of the seed is different depending on the type of seed. Without this, a single shooter enables high-precision aligned sowing to appropriately correspond to various seed shapes.
