Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for folding a band-shaped seedling of strawberries, green onions, rye or the like into a zigzag shape.

[0002]

2. Description of the Related Art Conventionally, a device for folding a tape-shaped banded seedling into a zigzag shape and packing the banded seedling in a storage container has been already known from Japanese Patent Laid-Open No. 2-76508.

[0003]

Generally, it is necessary to widen the width of the folded band-shaped seedlings so as to be substantially equal to the width of the seedling storage box of the planting device. , The strip-shaped seedlings were pulled out substantially horizontally from the supply part and then drooped, and they were folded further down, so if you set the drooping height to the extent that you can secure the folding length in one stroke, the taping device If the height of the taping device must be increased significantly or the seedling storage area must be lowered, the cost will increase and the workability will deteriorate.
Further, if the seedling storage section is lowered, it was not possible to secure a sufficient height for the storage section for band-shaped seedlings.

[0004]

According to the present invention, a folding device is arranged at substantially the same height on a substantially extended line of a band-shaped seedling feeding portion, and is fed above the folding device by the band-shaped seedling feeding device. A seedling lifting / feeding device that lifts the band-shaped seedlings and swingably hangs them down toward the folding device is arranged, and descends according to the folding thickness of the band-shaped seedlings under the folding device. The above-mentioned problem was solved by providing a seedling receiving device.

[0005]

In contrast to the folding device having the feeding part of the taping device as the feeding part, the feeding and feeding device hoists the band-shaped seedlings and hangs them down one by one, and the drooping band-shaped seedlings are fed to the feeding part by the folding device. They are folded in a zigzag shape at substantially the same height, and the seedling receiving device descends according to the folding amount of the band-shaped seedlings. Moreover, the taping device for banding the seedlings does not become abnormally high. Since the folding device has substantially the same height as the supply part, a wide storage part can be formed below it.

Guide rods 49, 49 are provided above 0, 40 to receive and guide the intermediate portion of the stem of the band-shaped seedling 14 that descends in a folded state so as not to project laterally.

Next, the transmission device will be described. The input sprocket 52 supported by the input shaft 41a on the outside of the main frame 41 is provided with the output roller 7 via the chains 53 and 54.
The small sprocket 56 mounted on the input shaft 41a is driven by a sprocket 55 attached to the shaft of the rotary shaft 58 of the main frame 41 via a chain 57 to drive the sprocket 60 of the rotary shaft 58. The friction wheel 61 having a small diameter provided at the end portion is pressed against the disc surface of the disc 63 at the end portion of the feed shaft 62 provided between the support frames 40, 40 together with the feed shaft 62 by the spring 65 to thereby transmit the power. Each connecting pin 71 of the chain 70 hung on a sprocket 68 attached to the other end of the feed shaft 62 and a sprocket 69 pivotally supported on the upper part of the main frame 41 while being converted into a right angle and decelerated.
.. each of which is projected laterally,
When the projecting piece 47 is fitted between the connecting pins 71 by rotating, the receiving plate 50 is slowly lowered by the rotation of the chain 70, and the crank arm 66 fixed to the rotating shaft 58.
Is linked to the swing arm 22 via a link 67, the swing arm 22 is connected to the fulcrum shaft 22a.
It swings back and forth about the center. Also, the input shaft 4
Belt 73 hung on pulley 72 attached to the lower end of 1a
Is each sprocket attached to the guide rollers 16 and 16 and a sprocket 75 axially supported on the side thereof.
The guide roller 1
6 and 16 feed the sandwiched seedling 14 downward.

The operation will be described below. The feeding speed of the feeding roller 7 of the taping device 1 and the guide roller 1 are described.
6 and 16 are the same as the winding supply speed, and the average folding speed of the folding device 10 is also the same as the above-mentioned speed, but since the swing arm 22 is driven by the crank arm 66 as described above, the folding rollers are 21a, 21
b is fast in the middle of the guide groove 19 and slowly reciprocates at both sides while temporarily stopping. As a result, the drooping band-shaped seedlings 14 become largely slack when the folding rollers 21a and 21b are on both sides, but the swing guide 1
8 returns to the center side by its own weight and swings to eliminate the slack.

Further, when the folding rollers 21a and 21b roll from right to left in the figure, the preceding folding roller 21a rolls while holding the belt-shaped seedlings 14 that have already been folded so as to suppress expansion. The subsequent folding roller 21b causes the hanging belt-shaped seedling 14 to be fed to the delivery roll 7
Are laid at approximately the same height, and are pressed firmly to roll and approach the side portion, the preceding folding roller 21a rises along the inclined portion 19a of the guide groove 19 and moves to the standby portion 19b. At that time, since the shaft 25 of the folding roller 21a pushes up the control plate 35, the seedling pressing rod 31 is rotated upward against the spring 32, and is separated from the bent portion of the folded band-shaped seedling 14 to end the movement. When reaching the vicinity, the shaft 25 and the cutout portion 37 of the control plate 35 are aligned with each other. At that time, since the seedling pressing rod 31 is urged downward by the spring 32, the seedling pressing rod 31 is rotated downward together with the control plate 35 and is protruded at the tip. 31a
However, the band-shaped seedling 1 wound around the folding roller 21b
Stick in 4 and press.

Then, when the swing arm 22 swings to the right, the folding roller 21b on the right side leads, while on the other hand,
Following this, the folding roller 21a on the left side is provided with the inclined portion 19
It rapidly descends along a and rides on the bent portion of the band-shaped seedling 14 so as to be crushed and flattened.
On the other hand, the end of the shaft 25 of the folding roller 21a rides on the control plate 35 and rotates downward against the tension spring 34 in the range of the elongated hole 35b, so that the shaft 25 passes over the control plate 35. Then, the control plate 35 causes the tension spring 34 to
It is pulled up by and is returned to the standby posture where it crosses the inclined portion 19a.

Since the feed shaft 62 slowly rotates the chain 70 during the folding operation described above, the receiving plate 50 slowly descends by the amount corresponding to the folding thickness, and when the receiving plate 50 reaches the lower end of the scraper 76. When the taping device 1 is stopped, the folding device 10 interlocking with it is also stopped. Therefore, the uppermost bent portion of the band-shaped seedling 14 is cut with a knife, and the receiving plate 50 is pivoted outward and retracted. After that, the folded band-shaped seedlings 14 can be taken out together with the scraper 76 and stored in a storage box. When restarting the work,
A new scraper 76 is set and the receiving plate 50 is returned and rotated to fix the end portion of the band-shaped seedling to the taping work and folding work.

[0016]

Since the present invention is constructed as described above,
The band-shaped seedlings 14 are pumped obliquely upward from the raising section, and then,
The taping device 1 can be hung down and folded at substantially the same height as the supply portion, and it is not necessary to make the taping device 1 for band-shaped seedlings abnormally high, which leads to cost reduction and highly efficient taping work. it can. Further, since the folding device 11 has substantially the same height as the supply part, it is possible to provide a seedling receiving device having a large vertical width below the supplying device, and the band-shaped seedlings that form a group are lengthened to provide a planting device. It is possible to reduce the number of seedlings supplied to the plant and improve the planting efficiency.
