Definitions
- the present invention relates to a seed paper used for drastically saving labor in hydroponics using a mat-shaped medium and hydroponics such as baby leaf which needs to sow many seeds uniformly.
- sowing with a sowing device can significantly increase the work efficiency in soil cultivation, but in the case of cultivation without using soil such as hydroponics, it is necessary to push the seed sowed into the medium, etc. There are problems such as difficulty in increasing efficiency compared to soil cultivation.
- Patent Documents 1 to 7 an adhesive having a necessary size and shape is applied to a base made of roll or sheet-like paper, and the seed is fixed to the base with the adhesive.
- a device that can greatly save sowing has been devised.
- both methods apply an adhesive to a relatively strong paper base, fix the seed with the adhesive, and provide a protective layer with PVA or paper on the surface to prevent seed detachment. It is mainly intended for cultivation and is suitable for sowing immature vegetables and seedlings with short growth periods for cultivation of general vegetables that require several weeks or months of cultivation. I can't say that.
- Japanese Patent Laid-Open No. 05-292805 Japanese Unexamined Patent Publication No. 07-274619 Japanese Unexamined Patent Publication No. 07-031219 JP 2000-060223 A JP 2002-305914 A Japanese Patent Laid-Open No. 10-136711 Japanese Utility Model Publication No. 06-060306
- the present invention was made to solve such problems, and it is an object of the present invention to provide inexpensive seed paper for significantly saving sowing work in the production of immature vegetables by hydroponics. And
- the seed paper according to the present invention made to solve the above problems has a plurality of planar shapes substantially the same as the target seeds provided on the mount made of water-decomposable paper, and the height of the target seeds Is characterized in that the target seed is adhered by a water-soluble adhesive inside each of the recesses having a depth of 1/10 to 1 times.
- the mount used in the seed paper according to the present invention is a paper that can be decomposed into water.
- the quality specified in JIS4501-1993 which is a JIS standard for toilet paper (basis weight 18 g / m2 or more, burst strength 78 kPa ( 10 sheets) or more, with ease of loosening within 100 s).
- the seeds targeted by the seed paper according to the present invention are all kinds of seeds that can be hydroponically cultivated and have a size of approximately 0.3 mm or more and 5 mm or less.
- Mizuna, Lolo Rossa, and the like which have recently been in great demand as baby leaves, can be suitably targeted for the seed paper according to the present invention.
- seeds are accommodated in each of the plurality of recesses provided in the mount, and the seeds are at least one of the height of the recesses because the shape of each recess is as described above. / 10, it is covered with a mount and is adhered to the mount with an adhesive, so that it adheres securely to the mount and can be transported or installed on a hydroponic medium (this can be done with a machine) )), The situation where the seeds are detached from the mount is avoided.
- the mount since the mount is water-degradable, the mount gradually decomposes during hydroponics.
- the decomposition by water can have both modes of physically separating by the presence of water and those decomposed by microorganisms in water.
- the mount component decomposed by water disappears from the surface of the medium and is removed from the medium by water. Since the decomposed paper component does not dissolve in water, it can be removed from the water by a filter or the like, and it does not accumulate in water like PVA. Therefore, long-term water circulation treatment can be performed in hydroponics.
- the seed paper manufacturing apparatus includes: a) Mount supply unit for supplying a long mount made of water-decomposable paper; b) an adhesive application unit that attaches a water-soluble adhesive to the one surface of the long mount supplied from the mount supply unit at a predetermined interval; c) a seed placement unit for placing a large number of seeds on the one surface of the long mount; d) a removal unit for removing seeds that did not adhere to the long mount from the long mount; e) a seed fixing unit that feeds the long mount by sandwiching the long mount that has passed through the removal unit with a pair of rollers that are softer than the seed.
- the seeds at the place where the adhesive is attached on the long mount are attached to the long mount. Seeds in other places do not adhere to the long mount. Therefore, by removing the seed that did not adhere in the removal unit from the long mount, the long mount that has passed through the removal unit is in a state in which the seed is attached only to the portion where the adhesive is attached.
- the simplest method for removing non-adherent seeds in the removal section is to use gravity. That is, non-adherent seeds can be removed simply by tilting the long mount or turning it upside down. Moreover, you may use positive removal means, such as a wind force and a vibration. The seed removed here can be used again in the seed placement section.
- the long mount is fed by rotating the long mount that has passed through the removal section with a pair of rollers softer than the seed.
- the seeds attached on the long mount are in a state where they are buried between the two rollers without being crushed by the rollers.
- a recess is formed in the long mount, and at least 1/10 of the height of the seed is embedded in the recess.
- the pressure between the two rollers spreads the adhesive existing between the seed and the long mount, which increases the bonding area and ensures that the seed adheres to the long mount. It becomes.
- the relative hardness of the two rollers constituting the pair of rollers so that the seed side is harder and the long mount side is softer.
- the resin adhering to the long mount will be pushed into the long mount side to a larger extent, and a recess that is 1/3 to 1 times deeper than the seed height will be formed on the long mount.
- the seeds are embedded in the seeds.
- a roll (or folded) long mount may be pulled out by the feed force of the pair of rollers of the seed fixing unit.
- ⁇ Long mount (seed paper) with seeds that has passed through the seed fixing part may be wound up or cut into an appropriate size into a sheet.
- the mount since the mount is water-degradable, the mount is gradually decomposed physically or by microorganisms during hydroponics, and disappears from the medium surface and is washed away with water. go.
- This decomposed product can be removed from the water with a filter or the like, and is not accumulated in water unlike PVA or the like, so that a long-term water circulation treatment can be performed in hydroponics.
- water-soluble adhesive that fixes seeds to the mount is also mixed in hydroponic water, but the amount of this adhesive used (attachment area) is very small in terms of the total area of the seed paper. It does not interfere with the circulation of water.
- the seed paper according to the present invention is a seed paper suitable for hydroponics, particularly in the production of immature vegetables such as baby leaves, sowing work can be greatly saved, and cost can be reduced. it can.
- the seed paper manufacturing apparatus can manufacture such seed paper in large quantities with high efficiency and at low cost.
- the schematic diagram which shows the whole structure of the seed paper manufacturing apparatus which is one Embodiment of this invention.
- Sectional drawing which shows schematic structure of the 1st buffer part B and the 2nd buffer part G of the seed paper manufacturing apparatus of embodiment.
- FIG. 3 is a schematic cross-sectional view of the mount transfer / seed crimping portion E of the seed paper manufacturing apparatus according to the embodiment.
- the seed paper manufacturing apparatus 10 of this embodiment is comprised from the following each part.
- -Mount supply unit A for supplying a long mount 11 made of water-decomposable paper
- the long mount 11 without applying excessive stress (tensile force) to the long mount 11 in response to intermittent movement requests of the long mount 11 by the adhesive printing section C and the mount transfer / seed crimping section E in the latter half 1st buffer part B for feeding -Adhesive printing part C for applying the adhesive 12 at predetermined intervals to fix the seeds 13 to the long mount 11 -Seed attachment part D for attaching seeds 13 to adhesive points applied to long mount 11
- the long mount 11 is referred to as a predetermined distance (this is referred to as a transfer pitch.
- the transfer pitch and the predetermined interval may be different.
- Mount transfer that intermittently feeds the seed, and the transport of the seed that also serves as the seed pressure contact that presses the seed 13 into the long mount 11 in order to securely fix the attached seed 13 to the long mount 11.
- Crimp part E Active removal part F using a soft rotating brush or the like to remove seeds that remain attached to the long mount 11 due to static electricity or excess seeds attached to the protruding adhesive In order to wind up the seed paper 15 with the seeds 13 adhered to the long mount 11 at predetermined intervals, which is intermittently sent, without excessive stress, the sudden movement of the long mount 11 is buffered.
- Second buffer part G -Mount winding part H for winding the seed paper 15 When the long mount 11 (or seed paper 15) moves, a plurality of appropriate numbers are used so that the long mount 11 (or seed paper 15) is not excessively stressed and is held with an appropriate holding force when stopped.
- both the first buffer part B and the second buffer portion G are provided with the long mount 11 so that an excessive force is not applied to the long mount 11 when the long mount 11 is intermittently transferred. It is a mechanism that hangs down and hangs inside. Therefore, both the first buffer part B and the second buffer part G have a width slightly wider than the width of the long mount 11, and the length (thickness) in the feed direction of the long mount 11 is several cm and the height (depth)
- a cylindrical body 21 having an upper opening of about 20 to 30 cm. Below the body 21 are a fan 22 that exhausts internal air, a motor 23 that rotates the fan, and a sensor 24 that can measure the height of the lower end (bottom surface) of the slack portion of the long mount 11 that is sucked. have.
- both buffer units B When the long mount 11 is passed from the mount supply unit A through the intermediate components B to G to the mount take-up unit H and the first buffer unit B and the second buffer unit G are operated, both buffer units B , The lower fan 22 of G rotates to draw the long mount 11 into the body 21.
- the sensor 24 measures the distance to the bottom surface of the long mount 11.
- the long mount 11 When the bottom surface of the long mount 11 is above the upper limit (upper limit) UL (dotted line), the long mount 11 is supplied by releasing the brake of the mount supply unit A or rotating the supply motor. When the lower end of the long mount 11 reaches the lower limit (lower limit) LL, the mount supply of the mount supply unit A is stopped. Note that the mount supply amount of the mount supply unit A at this time (the length of the long mount 11 drawn by the mount supply unit A) is independent of the transfer pitch described later.
- the sensor 24 is illustrated and described assuming an ultrasonic distance sensor, but a reflective or transmissive optical sensor is placed at the LL position (lower limit part) and UL position (upper limit part) of the side wall of the body 21. But a similar function can be achieved. Further, FIG. 2 shows an example in which the sensor 24 is provided on the lower side of the body 21, but a similar function can be realized even if it is installed on the upper side. If the suction force by the fan 22 is sufficiently secured, the overall direction of both the first buffer B and the second buffer G is simply to hang down the long mount 11 as shown in FIG. Even if it is left and right or in the opposite direction (the direction of suction upward), its function is not affected (the long mount 11 is a thin paper such as toilet paper, as will be described later. The motor 23 is not so strong.)
- FIG. 2 shows an example in which a small fan 22 is provided in each of the first buffer part B and the second buffer part G and used independently. Can also be distributed with pipes.
- the mount supply unit A and the first buffer unit B cooperate to supply the long mount 11 having a length required for the subsequent process at a necessary timing.
- the tension exerted on the fan 22 is due to the weak suction force of the fan 22 and there is no mass that affects the inertia other than the mass of the long mount 11 when the long mount 11 is moved. Even if an intermittent force is applied to the long mount 11, no strong tension is applied to the long mount 11, and even the long mount 11 that is thin and easily torn like a single toilet paper can be used stably.
- the seed paper 15 according to the present invention is mainly used for hydroponics of immature vegetables that grow in a short period of time
- the sprouted shoots easily penetrate the mount and extend upward.
- the roots When using with the mount side down, the roots must be able to easily penetrate the mount and extend into the medium.
- a thin and sparse paper that is easily decomposed with water is suitable as the long mount 11.
- JIS4501-1993 which is the JIS standard for toilet paper (basis weight 18g / m2 or more, burst strength 78kPa (10 sheets) or more, easy to loosen within 100s) Can be used.
- a plurality of rows (12 ⁇ 2 in FIG. 3) are formed at once as shown in FIG.
- the example shown in the column) can print the adhesive, which is efficient.
- the printing machine 31 and the mask 32 need to have a certain size in the feed direction, and the feed amount of the intermittent transfer of the long mount 11 is required. It becomes difficult to make it smaller than (transfer pitch). In this case, the previously printed adhesive comes into contact with the mask 32 at the next printing.
- the long mount 11 is lifted by using a push-up body 33 having a width substantially the same as the transfer pitch (size in the transfer direction), and the long mount 11 is moved. At that time, the push-up body 33 is lowered to the dotted line position. Thereby, it is possible to prevent the adhesive 12 printed on the long mount 11 from being rubbed against the mask 32 and the like to change the shape of the adhesive 12.
- the structure of the printing press 31 is not directly related to the object of the present invention, details are not shown. However, an appropriate amount of adhesive is held on the upper side of the mask 32, and a spatula-like mechanism element called a squeegee is used for each printing. By alternately moving in the width direction of the long mount 11, the adhesive 12 is printed on the long mount 11 through the holes of the mask 32, and various structures have been devised and manufactured.
- a plant-derived water-soluble adhesive such as starch paste or xanthan gum is used. Since these pastes are derived from plants, they are easily decomposed by microorganisms in water.
- the seed adhering portion D is provided with a horizontal back plate 41 and a vertical back plate 42 provided in the horizontal direction and the vertical direction along the transport direction of the long mount 11, and a transport direction for suction between the two.
- a suction substrate 43 having a large number of slits is provided.
- guide plates 44 are provided on both sides in the width direction.
- a mount holder J2 is provided on the back of the suction substrate 43. An example of the suction substrate 43 is shown in FIG.
- the long mount 11 is sucked by the action of the mount holder J2 while moving along the horizontal back plate 41, the suction substrate 43, and the vertical back plate 42, and the direction is changed from the horizontal direction to the vertical direction.
- the seed 13 is supplied to the space formed by the board 44 and the long mount 11 that changes the direction by 90 degrees. As a result, the seed 13 adheres to the adhesive 12 on the adhesive spot printed on the long mount 11.
- the seed 13 is carried to the left side of FIG. 1 by the horizontal movement of the long mount 11, but the long mount 11 is pulled up to change the direction in the vertical direction, and when it rises to a certain extent, it rolls down by gravity. Thus, a lump as shown in FIG. 1 is formed. In this lump, the seed 13 rolls on the long mount 11 and has a chance to pass over the adhesive point many times by moving, so the seed 13 is on the adhesive point of the long mount 11. The probability of adhering to the adhesive 12 is very high. On the other hand, the seeds 13 are basically excluded from the long mount 11 other than the adhesive point. From this point, the seed adhesion part D serves also as the removal part of this invention.
- the structure of the seed attachment part D is that the angle and the curve of the change are important as elements of the invention, except that the guide plate 44 provided on the left and right and the moving direction of the long mount 11 are changed from substantially horizontal to substantially vertical. is not. Further, in order to more securely hold the long mount 11 along the change in angle, suction force by a fan is used in this embodiment, but the movement of the long mount 11 in the transfer direction and the seed 13 Due to the dead weight of the mass and the friction between the two, the mass of the seed 13 can continuously maintain the state shown in FIG. 1 without the suction force by the fan.
- the long mount 11 to which the seeds 13 are attached is a seed press for fixing the seed attached to the adhesive spot on the upper mount 11 to the long mount 11 and the long mount 11 at a predetermined transfer pitch. It reaches the board transfer / seed crimping section E that also serves as a board transfer for accurately moving the sheet.
- compression-bonding part E is demonstrated using FIG.
- the seed 13 attached to the long mount 11 in the seed attachment portion D is only partially attached to the adhesive 12 printed on the surface of the long mount 11 as shown in the enlarged view 6A of FIG. Therefore, it is easy to fall off.
- this device is made of a soft sponge-like material and is rotated synchronously while pressing the two rollers 51 and 52 (note that only one may be driven and the other driven. .), And the long mount 11 is passed between them.
- the seed 13 is pressed against the long mount 11 to dent the long mount 11, and the bonding surface between the adhesive 12 and the seed 13 is expanded to extend the seed 13 into the long mount. 11 is securely fixed (enlarged view 6C).
- the rollers 51 and 52 are configured such that the hardness E1 of the roller 51 on the mount side is lower than the hardness E2 of the roller 52 on the seed side (expressed as hardness) in order to push the seed 13 into the long mount 11 side. E2 ⁇ E1) is better. However, if the hardness E2 of the roller 52 on the seed side is too high, and if the strength of the long mount 11 is too weak, the seed 13 breaks through the long mount 11 and falls off, so the roller 52 on the seed side. The hardness E2 needs to be set to an appropriate softness according to the type of the seed 13 to be targeted.
- rollers 51 and 52 are used on both sides, but the same function can be realized by using at least one of the belts.
- the seeds 13 are firmly bonded and fixed to the adhesive points of the long mount 11, but the seeds are adhered to the long mount 11 due to static electricity or the like at places other than the adhesive points, or the protruding adhesives May cause multiple seeds to adhere to one adhesive spot. Therefore, in order to remove those excess seeds 13, it is better to provide a positive removal part F with a soft brush or the like.
- FIG. 1 shows an example using a rotating brush, a fixed brush such as a soft brush may be used. Depending on the type of seed 13, such a positive removal part F may not be necessary.
- mount holders J1 to J3 that use a suction force by a fan to hold the long mount 11 are provided.
- 3 and 4 show the mount holding part J1 disposed immediately after the adhesive printing part C.
- the seed paper in this embodiment is used. Since the 15 long mount 11 is a thin and sparse material similar to a single toilet paper, it is very difficult to hold it with a roller or the like without breaking it. Also, an increase in friction and inertia is not preferable because a large tension is applied during movement.
- the mount holders J1 to J3 are installed in order to keep the long mount 11 stationary during intermittent transfer.
- a plurality of holes and slits 36 are provided in the transport surface 35 of the long mount 11, and air is sucked by the fan 37 from these holes and slits 36, whereby the long mount 11 is transported on the transport surface 35 Suck to 35 and hold.
- This holding force can be arbitrarily set according to the size and number of holes and the shape of the slit 36, and can be easily adjusted by the rotational speed (intake force) of the fan 37.
- the long mount 11 since no force other than friction (frictional force) between the long mount 11 and the conveyance surface 35 due to its own weight is not applied in the longitudinal direction, the long mount 11 is intermittently transferred. However, no strong tension is applied, and even thin and loose paper can be processed without tearing.
- FIG. 1 shows an example in which a small fan 37 is used independently in each of the mount holders J1 to J3, a single large fan is used and the suction force of the fan is distributed by a pipe or the like. You can also. Further, suction using static electricity may be performed instead of suction using a fan.
- the width of the long mount 11 can be freely determined from the width of the toilet paper to several tens of centimeters according to the cultivation method and the request on the apparatus side without greatly changing the basic structure of the apparatus. Can do.
- the adhesion pitch p of the seed 62 can be freely determined according to the type of plant to be used and the cultivation method (cultivation period). For example, if it is used for producing immature vegetables of Mizuna that grows quickly and grows up, the pitch is similarly 14 mm. For the production of immature vegetables, Lororo Rossa, which is easy to spread sideways, has an 18mm pitch, and for the same Lolo Rossa, it is a 28mm pitch for shipping as a vegetable instead of a baby leaf. Producing and providing can greatly increase the productivity of vegetable production. Note that the vertical and horizontal pitches are not necessarily the same.
- the width of the seed paper 60 can be increased. For example, when a seed paper having a width of 570 mm is used, seeding on one tray 71 is completed simply by placing one seed paper. .

これらにより、本発明に係るシードペーパーは水耕栽培に適したシードペーパーであり、特にベビーリーフ等の未熟野菜の生産において、播種作業を大幅に省力化することができ、またコストダウンすることができる。
・水可分解紙から成る長尺台紙11を供給する台紙供給部A
・後半の接着剤印刷部Cと台紙移送・種子圧着部Eによる間欠的な長尺台紙11の移動要求に応じて長尺台紙11に過剰なストレス(引張力)を与えることなく長尺台紙11を送給するための第一緩衝部B

・シードペーパー15を巻き取るための台紙巻取部H
・長尺台紙11(又はシードペーパー15)が移動する際に長尺台紙11(又はシードペーパー15)に過剰なストレスを与えず、且つ、停止時に適切な保持力で保持するために適宜の複数の箇所に設けられた、負圧を用いた台紙保持部J1~J3
本発明に係るシードペーパー15は、主に短期間で成長する未熟野菜の水耕栽培に使用するため、台紙側を上にして使用する場合は発芽した芽が容易に台紙を突き抜けて上に伸びることができる必要があり、台紙側を下にして使用する場合は発根した根が容易に台紙を突き抜けて培地に伸びることができる必要がある。これらのため、長尺台紙11としては、水で分解されやすい薄くて疎な紙が適している。例えば、前述の通り、トイレットペーパーのJIS規格であるJIS4501-1993に規定されている品質(坪量18g/m2以上、破裂強さ78kPa(10枚)以上、ほぐれやすさ100s以内)を備えるものを用いることができる。
種子付着部Dには、長尺台紙11の搬送方向に沿って水平方向及び垂直方向に設けられた水平背板41及び垂直背板42が設けられ、両者の間には吸引のための搬送方向スリットを多数有する吸引基板43が設けられる。また、それらの幅方向両側にそれぞれガイド板44が設けられている。吸引基板43の背部には台紙保持部J2が設けられている。吸引基板43の一例を図5に示す。長尺台紙11は、水平背板41、吸引基板43、垂直背板42に沿って進む間に台紙保持部J2の作用により吸引され、水平方向から垂直方向に向きが変えられるが、こうして両ガイド板44と、90度向きを変える長尺台紙11が形作る空間に種子13が供給されている。これにより種子13は、長尺台紙11に印刷された接着剤点上の接着剤12に付着する。
なお、種子13の種類によっては、このような積極除去部Fが不要な場合もある。
例えば図7に示す幅w=110mmのシードペーパー60を使用する場合、幅方向に8個の種子が並んでいるので、例えば長さを1160mmとするとシードペーパー60上には8×82=656個の種子が存在することになる。それを必要な長さに切って、トレイ71に横に並べて(図8のトレイの場合、5列)置くだけで、656個×5=3,280個の種子を数秒~数十秒で播種することができることになる。
