〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a roll sheet in which a paper sheet having a predetermined width is wound into a roll, and a paper sheet P fed out from this roll sheet 1 is attached to a rotating shaft 1a.
On the other hand, the brake body 2b, which is pivotally supported by the pivot support 2a, is always kept under tension from the roll sheet 1 by the brake part 2, which urges the brake body 2b, which is supported by the pivot support 2a, toward the side where it comes into pressure contact with the rotating shaft 1a and the side where it releases the pressure contact. The paper sheet P extends toward the glue supply section 3.

As shown in detail in FIG. 2, in the glue supply section 3, a glue storage tank 4 containing liquid glue moves in the front and back direction to fit into and separate from a slide guide 5 provided on the device main body side. It is provided in a cassette type so that it can be attached and detached. At the bottom of the glue storage tank 4, a plurality of glue dispensing holes 6 are vertically bored at predetermined intervals in the width direction. An opening/closing pin 7 for opening and closing is provided. This opening/closing pin 7 is integrally provided at the lower end of a vertically movable rod 9 that is vertically slidably supported in the glue storage tank 4 via a support metal fitting 8, and is connected to a spring provided between the vertical movement rod 9 and the support metal fitting 8. It is normally urged downward by lO, that is, in a direction that closes the glue dispensing hole 6. Further, the vertical movement rod 9 has a feeding amount adjusting screw 11 at its upper end.
By adjusting this feeding amount adjusting screw 11, the vertically movable rod 9 and the opening/closing pin 7 are vertically adjusted, so that the amount of glue fed out from the glue feeding hole 6 can be adjusted. On the outer periphery of the opening/closing pin 7, there is a rubber whose lower end touches the bottom surface of the glue storage tank 4 around the glue dispensing hole 6 to prevent glue from entering the glue dispensing hole 6, and which moves up and down as the opening/closing pin 7 moves up and down. A glue regulating body 12 consisting of a body is provided.

On the other hand, along the vertically moving rod 9, a reciprocating arm 14 that reciprocates up and down by an air cylinder 13 is disposed outside the glue storage tank 4. 4 is attached to and detached from the slide guide 5, a fitting groove L4a is formed below the feeding amount adjustment screw 11 of the vertically movable rod 9, into which the vertical movement rod 9 is fitted and removed. When the reciprocating arm 14 is pushed upward by the piston of the air cylinder 13, the vertically movable rod 9 and the opening/closing pin 7 are moved upward to open the glue dispensing hole 6 and dispense the glue, and the air cylinder 13 reciprocates. When the movable arm 14 is lowered, the vertically movable rod 9 is moved downward by the action of the spring 10, and the opening/closing pin 7 closes the glue dispensing hole 6, so that no glue is dispensed.

The air cylinder 13 is provided with a sheet vertical adjustment screw I7 that adjusts the distance between the paper sheet P and the tip of the opening/closing pin 7 by vertically adjusting the sheet support roll 15 and sheet support stand 16 that support the paper sheet P. ing.

Immediately after the glue supply section 3, an air blower part 18 is provided which functions to blow pressurized air onto the glue placed on the paper sheet P by the glue supply section 3 to spread the glue. A seed supply section 19 is provided downstream of this air blow section 18.

As shown in detail in FIG.
A seed sorting section 20 that separates seeds such as flowers into individual grains is communicated with a supply gutter 23 via a passage 21 provided with an optical sensor 22, and a seed drop port 24 is provided at the lower end of the supply gutter 23. A first shutter 25 that reciprocates by a cylinder mechanism is provided in the middle, and a second shutter 26 that reciprocates in the horizontal direction is provided below the seed drop opening 24.

The first shutter 25 may be reciprocated by an electromagnetic solenoid coil or a cam mechanism. When the seed supply port 26a provided in the second shutter 26 coincides with the seed drop port 24, a predetermined number of seeds are supplied onto the paper sheet P on which the glue is placed and adhere. The second shutter 26 is connected to an air cylinder 27
The lower end of a swinging arm 30 is pivoted to the reciprocating piston 28 via a pivot pin 29, and a pinion gear 32 is connected to the upper end of the swinging arm 30 to reciprocate around a rotation shaft 31. The rack gear 3 meshes with the pinion gear 32.
3 to reciprocate in the horizontal direction. code 3
4 is a support roll that supports the paper sheet P, and can be adjusted up and down.

A pre-drying section 35 is provided downstream of the seed supply section 19 for pre-drying the paper sheet P with seeds dropped onto a frame placed on the paper sheet P. , a first seed holding roller 36 which is driven and rotated is provided. The first seed holding roller 3
6 forms a detour to press the paper sheet P downward, and is rotated via a transmission mechanism 313a from the lower roller of a vapor sheet tensioning drive roller 37, which is a pair of upper and lower rubber rollers provided at the subsequent stage. A scraper 36b is provided which rotates under power and scrapes off glue adhered to its surface. Drive roller 3
Rotational power is transmitted to the lower roller 7 from a motor 38 provided below it via a transmission ti38a.

A second seed holding roller 40 is provided downstream of the vapor sheet pulling drive roller 37 at a part of the corner of the paper sheet P that is supported by the support rollers 39 and 39 and descends. The first and second seed pressing rollers 3
B, 40 can be replaced with one having a different diameter.

Further, a slack removing roller 41 for removing slack in the paper sheet P is provided between the support roller 39 and the lower end support roller 42 of the descending paper sheet P. This slack removing roller 41 is supported so as to be movable up and down within a predetermined range in the vertical direction, and is designed to remove slack so that the paper sheet P always moves with approximately constant tension. The paper sheet P discharged from the lower end support roller 42 is subjected to main drying in a main drying device 43,
The paper sheet is cut into a predetermined length by a cutting device 44 to obtain a paper sheet of a predetermined size. In the above configuration, the operations of each part are synchronized and controlled in conjunction with each other using a microcomputer (not shown) or the like. Further, the paper sheet P and the glue used are water-soluble ones that dissolve when a large amount of water (moisture) is supplied.

In the seed paper manufacturing apparatus configured in this way, a paper sheet P is fed out from the roll sheet 1 by the paper sheet pulling drive roller 37 driven by the motor 38 and moves at a constant speed, and the paper sheet P is moved at a constant speed. First, in the glue supply section 3, glue is placed in spots at predetermined intervals in the length direction in multiple strips and in the width direction at regular intervals, and the spot-shaped glue is flattened by pressure air from the air blower section 18. The seeds separated by the seed sorting section 30 are supplied to the dispersed glue in predetermined grains by the seed supply section 19. The roll sheet 1 is always fed out under tension by the brake section 2, and even when the device is stopped, unnecessary feeding of the paper sheet P is prevented by rotational acceleration of the roll. Also, when the roll sheet 1 is exhausted and needs to be replenished, The brake part 2 can be easily replaced by releasing the pressure contact with the rotary member 1a as shown by the imaginary line in FIG.

In the glue supply section 3, an opening/closing pin 7 is connected to the glue feeding hole 6.
Since the glue regulating body 12 is provided, the amount of glue dispensed is uniform, and there is no leakage of glue from the glue dispensing hole 6. In addition, the amount of glue to be fed is determined by the feeding amount adjusting screw 1.
1 can be adjusted arbitrarily, and when the glue in the glue storage tank 4 runs out, the glue storage tank 4 can be removed and replaced with a spare cassette type tank easily and in a short time. Since the distance between the paper sheet P and the paper sheet P can be adjusted using the sheet vertical adjustment screw 17, the state of adhesion of the glue to the paper sheet P can be selected.

In the seed supply section 19, the seeds separated one by one in the seed sorting section 20 are brought to the supply gutter 23 via the passage 21 while being detected by the optical sensor 22, where they are temporarily separated by the first shutter 25. When the seeds in each row are stored, the shutter opens and lowers.

When the second shutter 26 is opened, the seeds that have descended through the supply gutter 23 pass through the seed drop port 24 all at once, are placed on the paper sheet P, and fall onto the spread glue to be stuck. be done. The glue that stuck the seeds is paper sheet P.
The seeds are pre-dried while passing through the pre-drying section 35 due to the movement of the paper sheet P, and then the seeds are suppressed by the seed press roller 36 which bypasses the paper sheet P and passes through it, thereby strengthening the adhesiveness with the glue.

At this time, if excess glue adheres to the seed pressing roller 36, it is scraped off and removed by the scraper 36b.

As the paper sheet P moves thereafter, the seeds are pressed by the second seed pressing roller 40, maintaining reliable adhesion, and the slack is removed by the vertical movement of the slack removing roller 41, so that the paper sheet P is always maintained in a tensioned state. The glue is moved from the lower end support roller 42 to the outside of the apparatus, is dried in a main drying device 43, and is cut into a predetermined length by a cutting device 44, completing the production of seed paper. The size of the sheet paper produced in this way is, for example, the same size as a conventionally known seedling box, and the seedling box is placed on the bed filled with water and used for seedlings in a seedling facility. We will develop
When watered, the paper sheet P and glue dissolve in water and do not interfere with seed germination and growth. In addition, the amount of sowing is 1
It may be one grain per place, two to three grains per place, or it may be in a state close to that of a row seeding depending on the case, and in this case, the installation form of the glue and the amount of M to be set are selected as appropriate.

Furthermore, in the above embodiment, the entire manufacturing equipment can operate automatically and continuously, but this can be done manually by using a batch type machine in which paper sheets are cut one by one into a predetermined size. It is also possible to install the glue in the supply section 3 and supply seeds (seeds in the co-supply section 19) so that the device can be used separately.

〔Effect of the invention〕

As explained above, according to the seed paper manufacturing apparatus according to the present invention, the seed supply section that supplies seeds to the glue arranged on the paper sheet receives the seeds separated into individual grains and delivers a predetermined number of grains. a first shutter to be sent out;
The second shutter supplies the seeds sent from the first shutter onto the glue placed on the paper sheet, so when the first shutter has all the seeds for each row, the first shutter The seeds are opened and sent to the second shutter, and the seeds are sown in the glue that has already been placed by opening the second shutter, which is convenient because there is no need to hold the seeds until they are aligned in each row, and the timing is good. Can perform highly accurate seeding work. In addition, there is no time loss and sowing can be carried out more efficiently.

Furthermore, a sowing operation can be easily carried out by setting the number of seeds in each row arbitrarily.
