Description

[Detailed Description of the Invention] <Industrial Application Field> This invention provides a method for supplying thread in a belt-shaped seedling manufacturing machine when transplanting seedlings made of needle-shaped or rod-shaped seedlings such as rushes, etc., are divided into belts and transplanted. Regarding equipment.

<Conventional technology> Conventionally, as a device for forming strip seedlings of rushes, etc.
As shown in Japanese Patent Publication No. 148113, there is a device for planting each plant in a cup, and Japanese Patent Application Laid-Open No. 1999-1999. As shown in Japanese Patent Publication No. 196206, there is known an apparatus in which seedlings are divided for each plant and connected with tape at regular intervals to form connected seedlings, which are then transplanted while cutting the tape.

<Problem to be solved by the invention> However, in the above-mentioned device, each seedling is divided into seedlings,
Alternatively, a great deal of labor is required for force, planting, adhesive tape, etc., which is not only inefficient but also uneconomical in terms of the cost of producing seedlings.

On the other hand, the present inventors cut a strain that has grown to a certain diameter to a certain size, flattened it, fixed it in a strip shape to make a strip-shaped seedling, and transferred the strip-shaped seedling to the automatic feeder of a transplanter. Over the years, he invented a method of transplanting the plant by sequentially cutting and dividing it into quantitative parts.

The band-shaped seedlings are connected in a band-like manner and the base of the seedlings is connected and fixed using a thread in order to fix this connected state into an integral band-shaped seedling.

However, one important point is the structure and function of the thread supply device that passes the thread for connecting and fixing through the connected seedlings, and the thread reel that stocks the yarn and the thread reel for connecting and fixing the yarn as a mechanism for supplying these threads. A mechanism for applying a thread brake related to fixing strength without interfering with the thread insertion work is indispensable, but no device has hitherto existed that can address these problems.

Means for Solving the Problems> The apparatus of the present invention for solving the above problems firstly includes a moving line 25 for moving the connected seedlings 1a arranged in a belt shape.
and a rotating ring 32 that rotates around the moving line 25.
The connected seedlings 1a are provided to protrude inward within the rotary ring 32.
The thread feeding device is equipped with a thread feeding device that feeds the thread 31 from the distal end side as the rotating ring 32 rotates, and fixes the thread from the distal end to the connected seedling 1a prior to the base end side. The beak 44 is curved or bent on the tip side so that the beak 44 can be inserted into a position close to the part while being separated.

Similarly, the second invention includes a moving line 25 for moving the connected seedlings 1a arranged in a band shape, a rotating ring 32 that rotates surrounding the moving line 25, and a rotating ring 32 that projects inward within the rotating ring 32. The thread supplying device supplies yarn 31 to the connected seedlings 1a, and the yarn feeding device is provided with a thread close to the inner periphery of the rotating ring 32 so as not to come into contact with the end of the connected seedlings 1a when the rotating ring 32 rotates. The thread brake 53 that provides unwinding resistance to the thread 31 and the thread 31 are struck.

This is characterized in that it is provided with a thread reel 52 that allows the thread to flow.

<Function> Connected seedlings 1 arranged in a band shape moving on the movement line 25
A, the rotating ring 32 rotates while passing the connected seedlings 1a inside, and the beak 44 of the thread supply device protruding from the inner circumference of the rotating ring 32 connects the connected seedlings as the rotating ring 32 rotates. Thread is fed out and supplied to the fixed part one by one. At this time, the curved end of the beak 44 penetrates into the connected seedling itself in the vicinity of the connected fixed part and weeds, and at the same time lets out the thread 31 from its tip and smoothly and continuously entangles it around the connected seedling itself. Supply thread without any problem.

In addition, during the above-mentioned thread supply and fixing work, the thread brake 53 and the thread reel 52 are located close to the inner circumference of the rotating ring 32, so that they do not interfere with the weeding position of the linked seedlings la themselves, but also the linked seedlings la themselves. Since it is located in a position where there is no contact,
The width of the thread reel 52 is related to the amount of stock of thread, and the performance retention mechanism of the thread brake 53.
It is possible to design and assemble the yarn brake 53 without being limited by the width thereof.

<Example> The following is a detailed description of an example of the apparatus for producing rush seedlings. First, the rush seedlings used in the apparatus of this example are 10
The lower end of the hair root and stem of a strain that has grown to a diameter of around 0 mm is trimmed to a total length of about 200 cm, for example, and the strain is passed through a pressure side device (not shown) consisting of a pair of rollers and a pressure side roller. For example, a seedling formed on the pressure side in the form of a sheet with a thickness of about 20 mm is used.

FIG. 1 shows an overview of a method for producing strip seedlings by connecting the sheet-shaped bacterial strain with other strains, and a strip seedling producing machine for this purpose. An endless resin bridge connects the belt 12 to the roller 13. A short presser belt 18 is supported on the front end of the belt parallel to the belt 12, the front and rear ends of which are wrapped around rollers 16 and 17.

Between the heald 12 and the presser belt 18, the receiver is arranged so that the rear end of the sheet-like strain is partially overlapped with the front end of another strain, or A gap is formed in which the strip-shaped connected seedlings 1a that are brought into contact and connected in sequence are sent forward while being pressed.

Each of the rollers 1316 is a drive roller, and at the end of each roller shaft 19.21 there is a pusher wrapped with elastic rubber around the circumferential surface that rotates at approximately the same circumferential speed as the belt 12.18. Contact rollers 22, 23 are supported by respective shafts, and further in front of the rollers 13, 22 and 16, 23 are feed rollers 24, 24, 24, 24, 23, 23, 24, 24, 24, 24, 23, 23, 23, 23, 23, 23, 23, 23, 23, 23, 23, 23, 23, 24, 23, 23, 23, 23, 23, 23, 22, 23, 23, 23, 23, 23, 23, 23, 23, 23, 23, 22, 23 are supported, and in front of the rollers 13, 22, 16, 23, and 16, 23 are respectively supported.
26 is pivotally supported with a fixed gap above and below. The above-mentioned feed rollers 24 and 26 have spur gear-like irregularities formed on their circumferential surfaces, and both are driven in a direction to send out the bacterial strain forward. and said belt 12, 18 and roller 24.
．． 26 forms a moving line 25 for feeding seedlings.

A guide roller 27 and a chief roller 28a28b are provided above or below the pressing rollers 22 and 23, respectively.
Each tape roller 28a is arranged vertically and supported by a shaft.
Tapes 29a and 29b made of paper, cloth, or other material that have a certain strength against water and that bind or disintegrate fibers etc. by being immersed in water for a long time are wound and stocked around the tape 28b.

And belt 12. The connected seedlings 1a sent by the push roller 22. When passing between the tapes 23 and 23, the upper and lower tapes 29a and 29b are pressed against the pressure rollers 22 and 23, and their adhesive surfaces are pressed against the connected seedlings 1.
It is fed out so as to be pressed or adhered to each of the front and back surfaces of the underground rhizome portion of a. The roots of the rush seedlings protrude from the lower part of the tapes 29a and 29b, and the roots of the rush seedlings protrude from the upper part (the stems and the new shoots sprouting near the base end thereof), and the tapes 29a and 29b are attached to the base end. The attached seedlings 1a are further pressed by the next feed rollers 24 and 26 to strengthen the adhesion and are sequentially sent out.

As mentioned above, at the position between the tapes 29a and 29b being pressed and reaching the next feed rollers 24 and 26, the connected seedlings 1a are securely held by the rollers and healds,
An operation is performed to integrally fix the tapes 29a, 29b on both the front and back sides and the bacterial strain between them with the thread 31.

That is, the roller 24 in the moving line 25 of the connected seedlings 1a
, 26 and 22.23 (transfer gap 3)
0), a rotating ring 32 made of a pipe having its center at the flute between the tapes 29a and 29b is rotatably supported at right angles to the movement line 25.

On the outer periphery of the rotating ring 32, three rolling wheels 33a to 33c circumscribed at the left and right sides of the lower part and the center of the upper part are pivotally supported, and the lower rolling wheels 33b and 33c rotate as driving wheels, The rotating ring 32 is rotated clockwise as viewed from the rear.

That is, the rolling wheel 33b on the moving line 25 side is connected to the input shaft 3.
The belt 37 is rotated by the input from the input cabooly 36 fitted to the wheel 4, and the chain wheel 41 is wound around the sprockets 39b and 39c fitted to the input shaft 34 and the wheel shaft 38 of the other wheel 33c, respectively. The wheels 33b and 33c are both in rolling contact with the rotating ring 32 to drive it.

The upper roller 33a is supported by the tip of a swing arm 42 whose base end is supported by the body frame, and the swing arm 42 is supported by a spring 43 stretched between the swing arm 42 and the body frame. , which act to press the constantly rotating ring 32 against the wheels 33b and 33c.

On the inner periphery of the rotating ring 32, as shown in the figure, a beak 44 is formed which is bent into a beak shape so that the tip thereof forms a chevron shape in the direction of rotation, and protrudes toward the inside of the ring. The beak 44 is connected to a weeding rod 46 made of a bar whose proximal end is straight and whose distal end is curved toward a position close to the outside (seedling stem tip side) of the tape 29a29b in the delivery gap 30; A thread guide consisting of a pipe located inside the curve of the rod 46, whose base end extends parallel to the dividing rod 46 at a fixed interval, and whose distal end curves along the tip of the dividing rod 46. It is composed of a kite tube 47. The distal ends of the weeding rod 46 and the guide tube 47 are welded and fixed at the curved portions of the distal ends.

The base end of the dividing rod 46 is a round bar, but as it approaches the tip, the outside of the curve is successively sharpened to form an enon, as shown in Figures 5 (A) to (C). Furthermore, the tip of the beak is formed into a needle shape, so that it can smoothly penetrate the connected seedlings 1a on the moving line 25 and weed. In addition, the tip of the kite tube 47 ends in front of the most extreme end of the dividing rod 46 and is welded and closed at that position, or a hole 48 is bored at the end of the curved inner circumferential wall, and a hole 48 is formed to prevent the excess pressure. A spool-shaped thread letting-out guide with a circular groove 49a in the center is attached to the base end of the hole 48, so that the thread is smoothly paid out from the tip of the guide tube 47.

The base end of the beak 44 is fixed to a bracket 51 fixed to the inner periphery of the rotating ring 32.
The tip protrudes along the inner periphery of the rotating ring 32 in the opposite rotational direction of the ring, and the thread reel 52 is rotatably supported at the tip, and the thread 31 wound around the thread reel 52 is rotatably supported at the tip. passes through the bracket 51 and the guide tube 47, and as the rotary ring 32 rotates, the rollers 23.
The tapes 29a and 29b between the tapes 26 are fed out.

Also, within the placket 51, a reel-shaped yarn brake 53 is pivotally supported, which clamps the yarn 31 being let out from the yarn reel 52 toward the tip of the beak and provides unreeling resistance (frictional resistance). A spring 56 fitted to the brake shaft 54 elastically applies a clamping force to the thread. The clamping force can be adjusted by adjusting the elasticity of the spring.

Said thread reel 52. The thread brake 53 is attached close to the inner circumference of the rotating ring 32 together with the bracket 51,
Moreover, the protruding tip from the inner circumferential surface is located outside the relative trajectory line P (see FIG. 3) indicating the tip position so as not to hit the tip of the connected seedling 1a. Other thread reel 5
2 does not pass through the delivery gap 30, so the reel width can be made wider and a larger amount of yarn can be stocked without being restricted.

The unwinding end of the thread 31 is a tape 29a that is positioned in the delivery gap 30 before the rotation ring 32 is started.

29b and the seedling part, and when the rotating ring 32 is rotated while sending the connected seedlings 1a forward sequentially, the thread 3
1 is fed out toward the center of the ring, and is sequentially wound spirally around the tapes 29a and 29b on the front and back sides of the connected seedlings la, and the tapes 29a and 29b and the grass seedlings between them are integrally and connected and bound, forming a strip. The seedlings 1b are formed and sent forward.

At this time, in the illustrated example, the beak 44 rotates downward from above the stem of the connected seedling 1a, pushes the stem of the rush from above and passes through it, and the thread 31 is not obstructed by the stem of the rush. Tape 29a, 29b at the base of the seedling
The length of the thread 31 is wound around the part, the strength of which is adjusted by adjusting the resistance of the thread 31 from the thread reel 52.

In the above mechanism, the forward feeding movement of the seedlings and the rotating ring 3
Since the thread is paid out using the rotation of 2, the thread reel 52
It is not necessary to drive the yarn 31, and sufficient winding is possible by applying resistance to the yarn 31 by the yarn brake 53.

Further, since all movements are driven at a constant speed, the thread 31 is wound uniformly.

57 is a cutter that is pivotally supported on the side of the presser belt 18 and rotates at high speed in the direction of feeding the seedlings.The cutter 57 is used to correct the ends of the connected seedlings that have become uneven during the pressure side, cut them to a fixed size, and cut them into strips. This is the final height dimension of the seedling 1b.

Further, the peripheral edge of the cutter 57 is housed below the force/ter 57, and has a two-blade sawtooth shape that slowly feeds the seedlings in accordance with the circumferential speed of the belt while not receiving the seedlings to be cut. The receiver is provided with a cutter 58.

The outer periphery of the cutter 57 and the receiver 58 overlap with each other so that the cutting is reliable.The cutter 58 has a serrated shape and the receiver stops while the cutter 58 divides the seedlings evenly, allowing the belt to feed. Since they rotate in sync, there is no uneven cutting and no disturbance of the stem.

The receiver in the moving line 25 is connected to the tip of the heald 12 and the roller 24.
A table-shaped guide 61 made of left and right plates is fixedly installed in the delivery gap 30 in a position that does not obstruct the passage of the beak 44, and on the lower surface of both ends of the guide 61,

Then, as shown in FIGS. 7 and 8 (A) to (D), when the beak 44 passes, it is pushed back and stored in the lower part of the Kaidro 2, and when the beak 44 passes, it is mounted on the shaft 63. The structure is such that it returns to the protruding state again by a spring 65. Reference numeral 64 denotes a stopper for stopping the movable guide rod 2 at the return position, and is provided protruding from the bottom side of the guide 61.

As shown in FIG.
A housing groove 66 of a predetermined width is formed to accommodate the tip of the roller 2. With this structure, the protruding movable guide 61
4 is inserted inward from the outer circumference of roller 24, reducing the gap or step between the tip of movable guide rod 1 and the circumferential surface of roller 24, and increasing the transfer gap 3.
The purpose is to smoothly move the seedlings at o and prevent the seedlings from being disturbed.

Further, a star foil 67 having teeth slightly protruding from the upper surface of the receiving heald 12 is fitted on the right side protruding end of the roller shaft 19, and the movement of the seedlings is temporarily blocked by the beak 44 in the transfer gap 3o. The mechanism is such that the seedlings are forcibly and quantitatively fed so that the rear seedlings are not disturbed.
