Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling feeding device for a folding machine for banded strawberries, green onions, rye or the like.

[0002]

2. Description of the Related Art Conventionally, a device for vertically tapering striped seedlings from a supply section by a fixed guide and reciprocally moving a seedling cradle to fold down the striped seedlings into a zigzag shape is disclosed in Japanese Patent Application Laid-Open No. HEI-AO. It is already known from the publication of 2-154607.

[0003]

The known band-shaped seedling folding device described above guides the fed band-shaped seedlings descending by a fixed guide, and folds the band-shaped seedlings into multiple layers to form an extremely heavy seedling storage section. Since it was folded by not only lowering it but also reciprocating it left and right, the driving device became large, and the seedling storage part became slow at the lateral movement end, but at that time, the banded seedling at a constant speed. Since it hung down, it became loose, which made the position and shape of the folded portion unstable.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a supply portion for supplying a belt-shaped seedling is provided at an upper portion of a reciprocating folding portion.
In the vicinity of this supply part, the upper part of the slack eliminating device that regulates and guides both sides of the drooping-feeding seedlings is pivotally supported so as to swing left and right, and the sagging device is suspended so that the slack eliminating device is folded into a strip shape. The aforementioned problem is solved by providing a seedling accommodating portion which is configured to swing following the seedling and which descends below the folding portion but does not move laterally.

[0005]

[Operation] The strip-shaped seedlings continuously descending from the supply section descend while being guided on both sides by the slack eliminating device, and the folding section is
Folding the strip-shaped seedlings guided by the slack eliminating device while reciprocating, during which the slack eliminating device swings following the lateral movement of the folding device, and the folding portion is at the laterally moving end. When the speed becomes low, the band-shaped seedlings that descend and sag at a constant speed,
The band-shaped seedlings are gently squeezed by returning to their own weight to gently bend the band-shaped seedlings to remove the above-mentioned slack, and after the folding part forms a bent part, when the band-shaped seedlings move to the other side, the band-shaped seedlings become loose. The slack is removed by making it upside down by a take-off device.

Bosses that vertically extend over the sliding cylinder 48 are attached to the base of the above, these bosses are loosely fitted to the inclined shaft 46, and the rolling wheel 51 mounted on the tip of the receiving plate 50 is supported by the other support frame 40. As a result, the receiving plate 50 is moved up and down along the support frames 40, 40, and the receiving posture is as shown in FIG. It is configured so that it can be converted into a posture, and the middle part of the stem of the band-shaped seedling 14 that descends in a folded state above the left and right support frames 40, 40 does not project laterally. Guide rods 49, 49 are provided for receiving and guiding.

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.

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 belt-shaped seedlings 14 that descend in a hung posture are folded rollers 21a,
When 21b is on both sides, the moving speed becomes slower, but the descending supply speed is constant, so that the slackening device 18 greatly sags, but the slack eliminating device 18 follows the hanging part of the band-shaped seedling 14 by its own weight. By returning to the other side and swinging, the slack is eliminated, and the position and the folded shape of the folded portion can be appropriately formed.

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 succeeding folding roller 21b rolls while pressing down the belt-shaped seedlings 14 while laying down the drooping band-shaped seedling 14, and when approaching the side portion, the preceding folding roller 21a rises along the inclined portion 19a of the guide groove 19 and stands by. Move to 19b. At that time, the folding roller 2
Since the shaft 25 of 1a pushes up the control plate 35, the seedling pressing rod 31 rotates upwards against the spring 32, separates from the folded portion of the folded belt-shaped seedling 14, and reaches the vicinity of the movement end, 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 so that the projection 31a at the front end is folded. The belt-shaped seedling 14 wound around 21b is pierced and pressed.

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 backing plate 50 is returned and rotated to return to the upper side, the end of the band-shaped seedling is fixed to it, and taping work and folding work are started.

[0016]

According to the present invention, a supply portion for supplying the belt-shaped seedlings 14 is provided on the upper part of the reciprocating folding portion 12, and both sides of the belt-shaped seedlings 14 supplied by the supply are regulated in the vicinity of the supply portion. The upper part of the slack eliminating device 18 to be guided is rotatably pivoted and hung down so that the slack eliminating device 18 oscillates following the band-shaped seedlings to be folded in the folding part 12, Since the seedling accommodation portion that descends but does not move laterally is provided below the stacking portion 12, the folding portion 1 does not need to be moved laterally.
The band-shaped seedlings 14 can be folded and folded by a simple configuration in which the folding portion is reciprocally moved while lowering 2.
Further, when the folding-over portion 12 reciprocates, the moving speed becomes slower at the laterally moving end, whereas the drooping supply speed of the band-shaped seedling 14 is constant, so that the band-shaped seedling 14 loosens, but the slack eliminating device. 18 oscillates naturally following the band-shaped seedling 14 due to its own weight, whereby it is possible to fold it back into an orderly shape while keeping the bent portion at a fixed position without being entangled in the fold device at an inconstant speed.
