Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a paper tube seedling separation device that automatically separates a group of paper tube seedlings, row by row, which are grown in a seedling container in which individual paper tubes are separably connected. For example, a paper tube of 1° 1N is applied to Honda.
For example, a paper tube of 1°1゛i
It is attached to a processing device for sorting out I-containers.

Conventional technology This type of paper tube 1°I゛1 is made by growing the paper tube vertically.
However, if the seedlings are separated into individual paper tube seedlings or rows of paper tube seedlings, they tend to fall over if they are transported vertically.
Paper tube seedlings of Mt& are transported by laying them on their sides.

This type of separating device for paper cylinder seedlings is called "B'," which was published in Utility Model Publication No. 47-174G3. Separation devices that separate rows by row are known.

In addition, Utility Model Publication No. 49-2902 "Seedling feeding device for transplanter"
The seedlings are arranged on a seedling plate, and the seedlings that are about to be separated are pressed against the bottom of the seedling plate with a comb-shaped suppressing piece and fixed, and the roots of the seedlings are pierced 1°I'i with a curved needle bar to separate the seedlings. By rotating the needle bar and the abutting part of the rear support, each 1' blue is separated from the 1' blue row, and then the t & part support is separated from the 1' blue row. Separating devices are known in which each stroke is removed from a needle bar by rotating a holding portion of the body.

Problems to be Solved by the Invention The conventional technique described above (in the separation device for paper tube seedlings such as bamboo), individual paper tubes are used as a base [paper seedlings grown in paper tube seedling containers arranged in an orderly manner in one shape]. Paper tubes that are separated from tube 1゛blue m- into one row of paper tubes 6° in which each paper tube is closely attached, or that are grown in a paper tube seedling container in which individual paper tubes are arranged neatly in a honeycomb shape I'I''I Each paper cylinder of seedlings is separated row by row from the tightly attached track.

Therefore, the paper tube seedlings arranged at the back of the front row to be separated are held down from above with a pressing rod, or are pressed and fixed with a comb-shaped pressing piece, and the paper tube seedlings arranged at the back of the front row are separated. It's trying to pull away. However, since the paper cylinder of the paper cylinder seedling is only filled with soil, if it is strongly pressed and fixed with a pressing rod or comb-shaped pressing piece, the paper cylinder 1°1°1 may be deformed or the fit may be damaged. Because of this, it is not possible to press the paper tube seedlings too strongly, which results in some paper tube seedlings being taken out without being separated from the paper tube seedling row in the front row to be separated. The seedling rows of such a minute M device are the 1' blue row, which has a large number of excess paper tube seedlings that are in close contact with each other, and the irregular 4; It becomes.

Therefore, automatic separation devices for paper tube seedlings, such as the conventional technology described above, have not been put to practical use, and although they are less efficient than these,
At present, a paper cylinder seedling separation device such as that shown in Utility Model Publication No. 746, 1973-a, ``Single Soaking Separation Device'' is manually manipulated 11 times to separate each row.

In addition, Japanese Patent Application Laid-Open No. 61-744a, "Transplantation Device",
A seedling regulating device is provided integrally with the seedling regulating device, and includes a rotating regulating plate having an approximately semicircular outer circumferential surface with a spiral curve, which presses the paper barrels 1゛1°i located on both sides of the paper tube seedlings being separated from the front. A separation device is shown in which a paper tube seedling group is separated into individual paper tube seedlings and the seedlings are allowed to fall naturally.

This device attempts to separate each paper cylinder from a separate track, and in another embodiment, after separation, the paper cylinders 1° 1"1' are transferred in a line onto a conveyor, and then sent to a planting device. But it has been shown to be good.

However, if you try to separate each row using this device, since the ui regulating device and the 1'6 separating device are integrated, it will be difficult to transfer it to the i"i transfer mechanism by laying it on its side. Since paper tube seedlings must be allowed to fall naturally from a high position, the paper tube seedling rows delivered are uneven.
Therefore, it is impossible to move the separation device up and down in order to reduce natural fall because the seedling regulating device will be separated from the paper tube seedling row.

In addition, since the rotating 1゛η regulating device only has a small part to hold down the seedlings in the paper tube, the seedlings in the paper tube are bent in a dogleg shape and do not correspond accurately to the predetermined position for separation, resulting in uncertain separation. It is what it is.

Therefore, the present invention accurately regulates each paper tube seedling in the front row to be separated at a predetermined position for separation, and securely holds down each paper tube seedling arranged at the back of the front row to be separated. Be sure to separate the paper tube seedlings row by row,
It is an object of the present invention to provide a separation device for paper tube seedlings in which the paper tube seedling rows transferred from the separation device in the horizontal direction r511L form an orderly 1'+T row.

Means for Solving the Problems The structure of the present invention for achieving the above-mentioned requirements will be explained using FIGS. 1 to 4 corresponding to embodiments.

A method of separating each row from the opposite side.

Paper tube seedlings 1 are placed in the direction of paper tube seedling row P1 in the front row to be separated.
There is a seedling feeding mechanism a for transporting the group.

In front of the seedling feeding mechanism a, there is a mechanism that captures each paper cylinder seedling 1 in the front row and separates it from the paper cylinders 1l arranged at the back.
The seedling transfer mechanism 50 includes a paper tube seedling separation machine J1430 that transfers each paper tube seedling 1 by laying it down on its side.

A paper tube drawing shows the seedling regulating device 20 that presses from the front the outer wall of each paper tube 2 of the paper tube seedling row P2 arranged in a palindrome between the paper tube seedlings 1 of the paper tube seedling row P1 in the front row to be separated. minute 1isoyoko 3

It is also possible to widen the range. In this way, there is an effect that the center position in the transport direction of each paper tube seedling 1 of the paper tube seedling row P1 to be separated can be accurately regulated to a predetermined position for separation.

Similarly, each paper cylinder of the paper cylinder seedling row P1 in the front row to be separated, of the paper cylinder seedling row P2 arranged in a palindrome between 571,
The length in the vertical direction of the l'1°i regulating device 20 that presses the outer wall of each paper tube 2 from the front can be set to a sufficient contact length to prevent the paper tube, lli l from deforming or coming off. Paper tube seedling array arranged in a palindrome 1〕2 each paper tube 1° +
71 is firmly held down, and each paper tube seedling l of the paper tube seedling row P3 arranged directly behind each paper tube seedling l of the paper tube seedling row P1 in the front row to be separated is a paper tube seedling arranged in a palindrome. Since the paper tube seedlings 1 in the row P2 are reliably held down, each paper tube seedling 1 arranged at the back of the front row to be separated can be reliably held down.

In front of the seedling feeding mechanism a, apart from the seedling regulating device 20,
