[Detailed description of the invention]

[0001]

The present invention relates to a tape seedling production method in which seedlings for transplanting such as rush, leek, or raccoon are arranged and transported on a carrier, and the tape seedlings are adhered to a tape to form a continuous tape seedling. About the machine.

[0002]

2. Description of the Related Art Generally, transplantation of seedlings having strong root clumps, such as rush seedlings, has to be carried out by manually dividing one plant at a time or by scraping a large plant seedling with a beak. In addition, transplanting of seedlings that are soft and do not clump like leek or raccoon is difficult to transplant by scraping with a beak, and thus has to rely on manual labor. Therefore, there were difficulties in terms of the number of steps and accuracy for transplantation. On the other hand, the inventors of the present invention have developed a machine for taping and continuously transplanting rush seedlings while mechanically cutting and transplanting the same. Bulb seedlings such as green onions or raccoons are similarly taped to form continuous seedlings. Developed a machine that mechanically feeds and transplants it directly into the transplanting groove inside, and as a tape seedling manufacturing machine for this transplantation, the tape loaded into the tape holder and fed out is placed on the opposite surface of the roller that holds the seedling row It is proposed to send and tap.

[0003]

However, in the above-described tape seedling manufacturing machine, the remaining amount of the tape loaded in the tape holder is required when the worker supplies or replenishes the seedlings for transplantation onto the carrier. It is troublesome to check the condition at any time and monitor the tape for breakage. If the check is neglected and the tape breaks, the seedlings are released without being taped, and it is necessary to perform the operation again. Further, once the tape breaks, the tape loaded in the tape holder is reinserted into the opposing surface of the roller, and the tape seedling before the tape break occurs and the tape seedling to be manufactured are joined. Work must be performed, resulting in a remarkable decrease in work efficiency and an obstacle in producing tape seedlings.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems. The present invention conveys transplanting seedlings arranged in a direction perpendicular to the conveying direction by a carrier.
In a manufacturing machine in which the seedling row is attached to tape to form a continuous tape seedling, the tape loaded into the tape holder and fed out is sent out to the opposing surface of the roller that holds the seedling row to tap the seedling row. At the same time, a detector is provided between the tape holder and the roller to detect the remaining amount of the tape or the breakage of the tape, and the alarm is activated when the remaining amount of the tape decreases or when the breakage of the tape occurs. It is characterized by the following.

[0005]

[Function] In the present invention, the rush seedlings are formed into a continuous strip.
Bulb seedlings, such as green onions or raccoons, are arranged on a carrier at predetermined intervals according to the pitch to be transplanted.
Then, the row of seedlings transported by the transporter is attached to the tape fed out from the tape holder on the sandwiching and facing surfaces of the rollers to form a tape seedling. Here, when the remaining amount of the tape becomes small, or when the tape breaks in the middle, a detector provided between the tape holder and the roller detects this, and activates a buzzer or a warning device such as a lamp to notify the operator. Notifies that the remaining tape is running low or that the tape is out.
Therefore, the worker temporarily suspends the work to perform the tape replacement work and the tape connection work. Tape exchange work
This is completed by reloading the tape holder with a new tape, and the tape connection operation is performed by overlapping the end of the previous tape remaining between the tape holder and the roller with the replaced or remaining tape end. Complete by joining. Therefore, the tape can be configured as a continuous tape with the previous one and the replacement part, or the cut tape and the remaining tape without interruption, eliminating the work of inserting the tape into the rollers and the joining work of the tape seedlings. The production of continuous tape seedlings can be obtained very efficiently and easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to a tape seedling manufacturing machine for rushes shown in the drawings. In FIG. 1, a tape seedling manufacturing machine 1 places a seedling on a central portion of a main body and tilts a conveying belt 2 (transporting body). Provided. The seedling placing conveyor belt 2 is used to place the rush seedlings A that have been unraveled or stretched in advance by a seedling processing machine (not shown) or cut (pre-processed) as necessary. The rush seedlings A are supplied directly to the conveyor belt 2 from the seedling processing machine, or supplied by a worker from a spare seedling stand 3 provided above the seedling placing conveyor belt 2 in the inclined direction. In the case where the seedling layer is thin on the conveyor belt 2, the worker supplies seedlings from the spare seedling stand 3 even when the seedlings are supplied directly from the seedling processing machine. Further, a root alignment belt 4 is provided below the inclined side of the seedling placing and transporting belt 2, and the root alignment belt 4 rotates in synchronization with the seedling placing and transporting belt 2, and moves in the transport direction of the seedling placing and transporting belt 2. The roots of the rush seedlings A, whose stalks are arranged in orthogonal directions, are supported from below, and serve to align the ends of the roots in the transport direction. The safety cover 5 covers the upper surface of the root alignment belt 4 excluding the transport surface and the front surface on the worker side.
As shown in FIG. 2, the worker supplies and replenishes seedlings while sitting on a chair 6 supported on a shaft 1b protruding from the main body frame 1a so as to be able to freely move up and down. When the operation is completed, the chair 6 is rotated and stored in the main body frame 1a so as not to be in the way. Further, without providing such a dedicated chair, the folding chair may be stored in the storage tray 7 indicated by a dashed line, and may be taken out and seated at the time of work.

The seedling-carrying conveyor belt 2 and the root alignment belt 4 are made of a long, endless resin having irregularities on the surface, and the root alignment belt 4 includes front and rear rollers 8, 9.
The seedling-mounted transport belt 2 is wrapped around rollers 10,
It is wound around 11. Seedling conveyor belt 2
A short presser belt 12 provided in parallel and above is also supported by being wound around rollers 13 and 14, and the interval between the seedling placing / conveying belt 2 and the presser belt 12 is such that the belt-shaped seedlings A to be conveyed. Is formed in the gap for feeding while pressing. The rollers 9, 11, and 14 are drive rollers. In particular, the ends of the drive rollers 11 and 14 of the seedling placing and carrying belt 2 and the holding belt 12 rotate at substantially the same peripheral speed as the belts 2 and 12. Pressing rollers 15 and 16 having elastic rubber rubber wound on the peripheral surface thereof are coaxially supported by the respective rollers.
In front of 16, feed rollers 17 and 18 for feeding the band-shaped seedlings A sent from the press-contact rollers 15 and 16 while holding the same in the next process are axially supported with a certain vertical gap. The feed rollers 17 and 18 are formed with spur gear-shaped irregularities on the peripheral surface, and are both driven in a direction to feed the band-shaped seedlings A forward.

[0008] Guide rollers 19 and 20 are provided above and below the pressing rollers 15 and 16, respectively.
And the tape holders 21 and 22 are vertically arranged and supported, and each of the tape holders 21 and 22 has a certain strength against water and is broken down by immersing it in water for a long time, so that the bonding of the fibers and the like collapses. Tape made of paper, cloth or other material 2
3,23 are wound and stocked. Note that a specific example of the tape is a tape 23 shown in FIG.
Sets the solid part on the back of the tape to cellulose (paper) 24
The adhesive portion 24b on the surface is constituted by a tape mainly composed of starch. In this case, the cellulose 24a and the starch 24b are subjected to decomposition by microorganisms in the soil to promote the disintegration of the tape 23. In addition, since cellulose and starch are substances composed of carbon, oxygen and hydrogen, the decomposition products are expected to be water, oxygen, carbon dioxide and the like, and it can be inferred that they have no effect on crops and the environment. Therefore, commercially available tapes are made of petroleum-based polymer compounds such as polyethylene, polydimethylsiloxane, and natural rubber, and are very stable in the soil, are not easily degraded by light, heat, microorganisms, and the like. A biodegradable transplantation tape that collapses in a short period of time and does not cause any growth failure can be obtained, as compared to a case in which growth failure due to sulfur contained in natural rubber is expected. The tape 23 shown in FIG. 6 (b) is a transplanting tape in which a crystalline fertilizer or a growth regulating substance is attached to the adhesive part of the existing tape, and the solid part which is the back of the tape is subjected to back treatment. And a kraft paper layer 25c to which the fertilizer (3) is applied.
25e crystals such as element, trace element), rooting agent, germination promoter
Is attached. This tape 23 finds the validity of the tape by adding a positive factor of the growth of the crop to the mentally negative factors such as the growth failure of the crop and the residual in the soil due to the existing tape, and finds the validity of the tape, thereby saving labor and increasing the yield. Is intended to increase productivity.

The upper and lower tapes 23, 23 described above are used when the band-shaped seedlings A sent by the belts 2, 12 are sandwiched between the opposing surfaces of the pressing rollers 15, 16 and pass through.
It is pressed against the pressing rollers 15, 16 together with the band-shaped seedling A,
The adhesive surface side is pressed or adhered to each of the front and back surfaces of the rhizome portion of the band-shaped seedling A, and is sequentially fed out. Then, the roots of the rush seedlings A protrude from the lower portions of the tapes 23, 23, and the sprouts germinating near the basal portion thereof protrude from the upper portions. The band-shaped seedlings A adhered to the portion are further pressed by the next feed rollers 17 and 18 and are sequentially sent out while strengthening the adhesion. As described above, the belt-shaped seedlings A are securely held by the rollers and the belt at the position where the tapes 23 and 23 are pressed and reached to the next feed rollers 17 and 18. The tapes 23, 23 and the seedlings of the band-shaped seedlings A sandwiched therebetween are subjected to a thread hooking operation of integrally fixing the seeds with a beak provided in the rotating ring 26 and a thread (not shown). Then, the tape seedling securely fixed by the tape and the thread is sequentially wound in a roll shape on a reel 27 that is driven to rotate. In addition, a rotary cutter 28 and a receiving cutter 29 are provided in the transport path of the belts 2 and 12 described above.
It may be cut so as to correct the tip of the band-shaped seedling A that has become uneven at the time of pressure bias by the belt so that it becomes a fixed size,
At this time, the generated chips are guided by a guide plate B provided below and stored in a removable chip box C. In addition, in transplanting bulb seedlings such as green onions, radish, etc., since the transplant pitch is long and the upper and lower tapes between the bulbs adhere to each other, the above-described thread winding step or cutting step is not particularly necessary, The tape 27 is wound around the reel 27 while being taped.

Next, the alarm device at the time of the above taping operation will be described. As shown in FIGS. 3 and 4, the tape holders 21 and 22 provided on the upper and lower sides are two slits 30a formed in the circumferential direction. , 30a and tape 2
The small-diameter receiving portion 31 into which the third member 3 is loaded is formed to protrude. A switch 33 supported by a bracket 32 is provided on the opposite side of the slits 30a, 30a from the tape loading side, and the switch 33 constitutes a detector for detecting the remaining amount of the tape. Here, the tapes 23 and 23 are loaded into the tape holders 21 and 22, respectively.
When the tape 23 is fed out between the opposing surfaces of the pressing rollers 15 and 16 by passing the leading end of the tape 23 through the guide rollers 19 and 20, and the taping operation is performed, the band-shaped seedlings A conveyed by the conveying belt 2 are pressed by the pressing rollers as described above. The upper and lower tapes 23 and 23 adhere at portions 15 and 16, respectively.
Is appropriately paid out accordingly. With the feeding of the tape 23, the tape holders 21 and 22 move to the shaft support portions 21a,
The sensor bar 3 of the switch 33 rotates around the center 22a.

Go in and out of 0a. When the tape 23 is sufficiently left, the sensor bar 33a once enters the slits 30a, 30a with the rotation of the tape holder.
3, the switch 33 is not turned on, and the remaining amount of the tape decreases and when the tape 23 approaches the core 23a, the sensor bar 33a opens the slits 30a, 30a.
a, and the switch 33 is turned on. When one of the upper and lower switches 33 is turned on, FIG.
As shown in (1), the alarm circuit composed of the power supply 34, the main switch 35, and the buzzer 36 is closed, and the buzzer 36 operates.

In this case, when the remaining tape amount decreases, the switch 33 is once turned on, but when the tape holder rotates next, the sensor bar 33a is disengaged from the slits 30a, 30a and the switch 33 is turned off. Therefore, while the tape holders 21 and 22 are rotating, the switch 33 is alternately switched on and off, and the buzzer 36 prompts the operator to change the tape with an intermittent sound. The core 23a of the tape 23 loaded in the tape holders 21 and 22 is substantially slit 30a,
The sensor bar 33a of the switch 33 operates the buzzer 36 immediately before or slightly before the tape comes off the core 23a, so that the operator operates the stop button 37a of the operation panel 37 or the foot pedal. 3
7b, the power supply to the drive motor 38 of the tape seedling production machine is cut off with a margin before the end of the tape 23 comes off the pressing rollers 15 and 16, and each of the conveyor belts 2 and 12 is stopped. it can. In the tape replacement operation, the seedling supply operation is interrupted, and the tape holders 21 and 22 are stopped.
Reload a new tape into the tape holder 2
This is performed by superimposing and joining the leading end of a new tape that has been replaced with the last end of the tape remaining between the pressing rollers 15 and 16 and the pressing rollers 15 and 16. As a result, the tape is replaced with a continuous tape 23 which is not interrupted by the previous one.
The tape exchanging operation can be completed quickly without removing the band-shaped seedlings A located between the pressing rollers 15 and 16.

Further, another example of the alarm device will be described with reference to FIG.
Switches 39, 39 constituting a first detector in the transport path of the tape 23 to the guide rollers 19, 20;
Is provided. Further, in the transfer path of the tape 23 reaching the guide rollers 19 and 20 and the pressing rollers 15 and 16,
Are provided. When the tape 23 is fed out of the holders 21 and 22 and the transfer path of the tape 23 is displaced forward in the drawing, the first switches 39 and 39 described above use the sensor bars 39a and 39 to detect the tape 23.
a is detected and the switches 39, 39 are turned on. Then, the second switches 40 and 40 are connected to the sensor bar 40.
The switches a and 40a are turned on when the tape 23 runs out. Each of the switches 39, 39, 40, 40 is connected in parallel to the buzzer 36 as shown in the circuit diagram of FIG. 8, and when any of the first switches 39, 39 is turned on, the operator is instructed. Informs that the remaining tape is low with an intermittent tone. Also,
When the tape 23 is completely lost, or when the tape 23
Is turned off halfway, one of the second switches 40, 40 is turned on, and the buzzer 36 is operated continuously.
Therefore, in this embodiment, an alarm can be issued not only when the remaining amount of the tape 23 is reduced, but also when the tape is cut off in the middle, so that the alarm device can be configured to surely cut the tape. Reference numeral 41 denotes a timer for periodically intermittently operating the buzzer 36 when one of the switches 39, 39 is turned on.

The tape 23 is made up of tape holders 21 and
It is difficult for the operator to directly check the remaining amount of the tape because it is loaded behind the tape 2, but the slits 30 a of the tape holders 21 and 22 in the first embodiment described above are different from those in FIG.
(A) also serves as a window for checking the remaining amount of tape, and in the second embodiment, (b), (c), and (c) of FIG.
As shown in (d), the confirmation window 30b is perforated in the tape holders 21 and 22 and the mark 30 with the remaining scale is attached.
By pasting c, it is desirable that the visual confirmation by the operator can be performed at the same time. Furthermore,
In the embodiment, the buzzer 36 is used to warn the user of the replacement time of the tape 23. However, a lamp may be used instead of the buzzer 36, or the power supply to the drive motor 37 is cut off in accordance with the operation of the buzzer and the lamp, and the conveyance belt is stopped. Etc. can be forcibly stopped.

[0014]

According to the present invention constructed as described above, the seedling row A transported by the transporting body 2 is affixed to the tape 23 pulled out from the tape holders 21 and 22 while being held between the opposing surfaces of the rollers 15 and 16. Wear and form a continuous tape seedling. When the remaining amount of the tape 23 becomes small, a detector 33 provided between the tape holders 21 and 22 and the rollers 15 and 16 detects this, and activates a buzzer 36 or an alarm device such as a lamp to notify an operator of the remaining tape. An alarm promptly and reliably warns of a decrease in the amount, that is, a time to change the tape. Also,
If the tape breaks in the middle, the detector 40 detects this and activates the alarm 36 in the same manner. Therefore, the tape replacement and connection work is completed only by overlapping and joining the previous tape end remaining between the tape holder and the roller with the new tape replaced or the leading end of the remaining tape. In addition, the operation of inserting the tape into the rollers and the operation of joining the tape seedlings to each other are omitted, so that continuous production of tape seedlings can be performed extremely simply and quickly.
