Here, as the mat, one having water absorbency or air permeability is used. In particular, synthetic resin foams such as phenolic resin foams (hereinafter referred to as resin foams) which can easily insert seeds into the surface of the mats are used. What is called a body) etc. are used suitably. When a mat that can easily press-fit the seeds is used, the seeds can be buried in the mat surface without crushing the seeds simply by pressing the surface of the sown mat with a press machine, and the entire seeds can be easily placed on the mat surface. Can be buried in In addition, when the whole seed is buried in the mat, the seed does not protrude from the surface of the mat, so that the seed mat can be stacked and stored, and the seed does not peel off from the mat when the seed mat is stacked, A seed mat with excellent handling properties can be manufactured. When the mat is made of resin foam, the cells (bubbles) can be buried in the mat without breaking the cells (bubbles) and damaging the seeds. Can be held without falling off. Alternatively, a mat whose surface is coated with an adhesive in advance may be used. In this case, by pressing the surface of the sown mat with a press machine, the seeds can be embedded and adhered to the surface of the mat, and the seeds can be securely adhered and fixed to the mat. As a result, it is possible to reliably prevent the seeds from dropping off the mat during transportation of the seed mat. Further, as the shape of the mat, a plate shape such as a square shape or a rectangular shape is suitably used. Thereby, while the mat can be easily conveyed by the conveying device, the productivity of the seed mat can be improved,
Mats can be stacked, and the transportability and handleability of the mats can be improved.

A belt conveyor or the like is used as the transport device. In addition, since the guide portions are provided upright on both sides in the transport direction of the transport device, it is possible to prevent the mat from shifting from the transport surface during the transport of the mat. Further, it is preferable to dispose a sensor such as a photoelectric sensor for detecting that the mat has been conveyed to each device on the upstream side of each device of the seeding machine and the press machine. This allows the sensor to detect that the mat has been transported to each device, so that it is possible to start driving each device almost simultaneously with the mat being transported to each device. The seeder can be prevented from being sown on the transfer surface of the transfer device by driving the seeding machine when not being transferred, and energy can be saved.

The pressing machine includes a pressing plate and a pressing driving unit for moving the pressing plate up and down. The pressing device presses the entire surface of the mat at one time, and the pressing device is rotatable provided above the conveying surface of the conveying device. And a press that sequentially presses from one end of the mat while inserting the mat between the conveying surface and the press roller. The pressing amount of the mat by the press machine varies depending on the type of the seed, the material of the mat, and the like, but is adjusted so that the press machine presses the seed into a predetermined amount. In particular, when a mat made of a resin foam such as a phenolic resin foam or the like and into which the seeds can be easily inserted is used, the entire seeds sown on the mat surface are buried in the mat and the mat surface is flush. It is preferable that the mat be adjusted so that the surface of the mat can be pressed (the gap between the mat and the conveying surface is smaller than the thickness of the mat). This makes it possible to bury the entire seed in the mat without fail, and to flatten the surface of the seed mat without projecting the seed on the surface of the seed mat manufactured by the seed mat manufacturing apparatus. Therefore, the seed mats can be stacked and transported and stored without dropping the seeds, and the handleability of the seed mats can be improved. Also, the mat can be compacted to improve the mechanical strength of the mat. In addition, a seed leveling unit including a brush or the like for uniformly leveling the seeds sown on the surface of the mat may be provided between the seeder and the press.

According to a second aspect of the present invention, there is provided the seed mat manufacturing apparatus according to the first aspect , wherein the mat supply unit is provided on the upper side of the transport surface of the transport device at right angles to the transport direction of the transport device. It has a configuration including a standing stopper plate, a mat insertion opening formed by cutting out a lower end portion of the stopper plate, and guide plates standing on both sides of the transfer device.

[0017] Thus, in addition to the operation of claim 1, having the following effects. j . Since guide plates are erected on both sides of the transport device,
It is possible to prevent the mat from protruding from the side of the transfer device or from being shifted from the transfer surface, and the transfer device can smoothly transfer the mat. k . A stop plate erected on the upper side of the transfer surface, and a mat notch formed at the lower end of the stop plate, so that the mat can be sequentially conveyed from the mat insert, and especially the plate When a plurality of mats are stacked and supplied to the mat supply unit, the mats in contact with the conveying surface (the lowermost mats of the stacked mats) are arranged one by one in order from the mat insertion opening to the downstream side of the conveying device. And the mat can be automatically and continuously conveyed.

[0018] Here, the mat insertion opening, the mat is formed to a size that can be inserted in substantially the same shape as the conveying direction end surface of the mat being conveyed by the conveying device. The opening height of the mat insertion opening is larger than the thickness of the mat and smaller than twice the thickness of the mat. Thus, the stacked mats can be sequentially conveyed one by one from the mat insertion opening to the downstream side of the conveying device.

According to a third aspect of the present invention, there is provided the seed mat manufacturing apparatus according to the first or second aspect , wherein the water sprayer is provided with a horizontal cover portion erected on both sides of the transfer device. A cover body having a cover portion connected between the opposed horizontal cover portions, a spray portion disposed in the cover body, and a water supply portion connected to the spray portion. Have.

Accordingly , the following operation is obtained in addition to the operation of the first or second aspect . l . It has a cover body consisting of a lateral cover part and a cover part connected between the opposing lateral cover parts, and since the cover part has a spray part, water sprayed by the spray part flows around the transfer device. Spattering can be prevented. m . Since water can be sprayed toward the surface of the mat conveyed at a constant speed by the conveying device, water can be supplied to the mat surface almost uniformly and evenly.

[0021] Here, as the spraying section, next to the cover inner wall and the cover inner wall, it is 1 or more disposed towards the spray outlet to the conveying surface of the conveying device. Further, an upper cover may be provided on the horizontal cover portion and the upper end of the cover portion, and a spray portion may be provided on the lower surface of the upper cover. In addition, as a spray port, such as one having a large number of spray ports capable of spraying water on substantially the entire transport surface of the transport device surrounded by the cover body, water is uniformly spread on the surface of the mat transported by the transport device. A sprayable shape is used.

According to a fourth aspect of the present invention, there is provided a seed mat manufacturing apparatus according to any one of the first to third aspects, wherein the press is disposed on both sides of the transfer device. Bearing unit, the press roller which is supported by the bearing unit and is disposed at a right angle to the conveying direction of the conveying device, and a roller driving unit which drives the press roller to rotate. I have.

Accordingly , the following functions are provided in addition to the functions of the first to third aspects. n . Just by transporting the mat with seeds sown on the surface by the transport device, the mat can be inserted between the transport surface of the transport device and the press roller, and pressing the mat surface with the press roller while transporting the mat, The seeds sowed on the surface of the mat can be pressed into the mat and buried. o . Since the press roller is rotationally driven by the roller drive unit, the mat can be smoothly inserted below the press roller (between the conveying surface and the press roller), and one end of the mat (the downstream side in the conveying direction). (The end of the mat). p . Since the press roller can sequentially press the mat from one end side, the surface of the mat of various sizes can be pressed regardless of the size of the mat, and the usability and versatility of the press can be improved. At the same time, since the surface of the mat can be pressed only by the press roller, the size of the press can be reduced.

[0024] Here, as the press roller is rotated at 1 to 2 times of the mat conveying speed of the conveying device. Thereby, the mat is smoothly inserted between the press roller and the transfer surface of the transfer device. In addition, a roller driving unit that rotationally drives the press roller may also be used as a driving unit of the transport device.Especially, when a belt conveyor is used as the transport device, a transport belt driving roller and a press roller of the belt conveyor are used. The press roller may be connected with a chain or the like, and the press roller may be rotated together with the rotation of the transport belt driving roller. This eliminates the need for an independent motor or the like for driving the press roller, thereby reducing the number of parts of the seed mat manufacturing apparatus and improving productivity.Also, the press roller and the conveyor belt driving roller can be connected with a chain or the like via a sprocket. When connected, the rotation speed of the press roller can be easily changed to 1 to 2 times the rotation speed of the conveyor belt driving roller only by replacing the sprocket. In addition, when the rotation speed of the press roller is lower than 1 time of the mat transfer speed of the transfer device, wrinkles on the surface of the mat tend to lower the quality of the seed mat, and the mat transfer speed is more than 2 times. If it is too early, there is a tendency that the mat is cracked and the mat tends to be damaged, which is not preferable. The distance between the press roller and the transfer surface of the transfer device depends on the material of the mat and the type of the seed, but is set so as to be buried on the surface of the mat without crushing the seed. When the entire seed is buried on the surface of the mat, the seed can be buried in the mat and the mat surface can be flattened (smaller than the thickness of the mat). It is formed at intervals that can be depressed.

[0027] According to a sixth aspect of the present invention, in the seed mat manufacturing apparatus according to the first aspect of the present invention, the transporting device may be configured such that the transporting device has a predetermined interval perpendicular to a transport direction of the mat. And has a configuration having a crossed belt having a plurality of crossings erected in the above.

Thus, in addition to the functions of the first to fifth aspects, the following functions are provided. r . The mat can be placed and transported between the crosspieces of the belt with the crosspiece, so that the mat can be prevented from being displaced from the transport surface during the transport of the mat, and can be sowed on the surface of the mat almost uniformly, so that the seeding accuracy can be improved. Can be improved. s . Since the mat can be placed between the crosspieces of the belt with the crosspiece, the mat can be transported at regular intervals, and the workability of manufacturing the seed mat can be improved.

Here, it is preferable that the interval between the crosspieces is substantially the same as the length of the mat in the transport direction. This allows
The mats placed between the crosspieces can be reliably prevented from shifting during conveyance, and the mats can be placed at predetermined intervals on the conveyance surface without wasting the conveyance surface of the belt with the crosspiece,
The production efficiency of the seed mat can be improved. The height of the crosspiece is preferably formed to be 1/2 to 3/4 times the thickness of the mat. This makes it possible to reliably support the end surface of one mat in the conveying direction with the crosspiece, and to prevent the mat from shifting during the conveying operation. In addition, as the height of the cross becomes lower than 1/2 times the thickness of the mat, the tendency of the mat to shift over the cross during transportation of the mat increases, and the height of the mat becomes more than 3/4 times the thickness of the mat. As the height increases, the overall thickness of the crossed belt increases, and the tendency of lack of handleability increases. In addition, when the plate-shaped mat is supplied to the crossed belt by the mat supply section according to claim 3, the crosspiece is obstructed. Become a mat
There is a tendency that it is difficult to supply the sheets one by one, which is not preferable.

According to a seventh aspect of the present invention, there is provided the seed mat manufacturing apparatus according to any one of the first to sixth aspects, wherein the mat is a plate-like body made of a phenolic resin foam. It has a configuration.

Thus, in addition to the functions of the first to sixth aspects, the following functions are provided. t . By pressing the seeds sowed on the surface of the mat with a press machine, the cells (bubbles) of the mat can be easily broken with the seeds and buried in the mat without damaging the seeds. The seeds can be held on the mat without falling off due to the entanglement of the hairs of the part and the seed epidermis. u . Since the mat is lightweight, the seed mat manufactured by the seed mat manufacturing apparatus can be easily transported. v . Since the mat is pressed by the press, the mat can be compacted and the mechanical strength of the mat can be improved.

Here, as the phenol resin foam,
A resin obtained by mixing a resole type phenol resin with an acidic curing agent, a surfactant for adjusting bubbles and absorbing water, and an organic foaming agent and foaming the mixture is used.

As described above, the apparatus for manufacturing a seed mat according to the first embodiment has the following functions. (1) Since the seed mat manufacturing device having the transfer device and the seeding machine is provided with a mat supply unit, a water sprayer, an adhesive supply device, and a press machine, the mat is transferred by the transfer belt of the transfer device. Seeds are sowed and pressed into the surface of the mat, the seed is buried in the surface, and a seed mat having a flattened surface can be automatically manufactured, thereby improving the productivity of the seed mat. (2) Since the seeds sowed on the surface of the mat are buried on the surface of the mat by a press machine, the seed mat can be produced not only for paddy rice and feed rice, but also for seed mats of various sizes and shapes such as sorghum. It can be manufactured by an apparatus, and the versatility of the seed mat manufacturing apparatus can be improved. (3) Since a mat supply section, a water sprayer, an adhesive supply machine, and a press machine are provided above the conveyance belt (conveyance surface) of the conveyance device, simply attaching each device to the conveyance device, A seed mat manufacturing device can be easily manufactured, and maintenance of each device can be easily performed. (4) Since the mat supply unit including the stopper plate and the guide plate is provided on the upstream side of the conveyance device, the mat can be prevented from protruding from the side of the conveyance device and from being displaced from the conveyance surface. The transportability can be improved, and even when a plurality of plate-shaped mats are stacked and supplied, the mats can be prevented from being displaced or falling down from the transport surface, and the workability of supplying the mats can be improved. (5) Since the notch has a notch formed mat insertion opening at the lower end thereof, mats can be sequentially conveyed one by one from the mat insertion opening, and the mat is automatically and continuously supplied. Thus, the seed mat can be continuously produced in a short time, thereby improving workability and productivity. (6) Since the water sprayer has a cover body consisting of a horizontal cover, a cover, and an upper cover, and the sprayer is disposed inside the cover, the water sprayed by the sprayer flows around the transfer device. Spattering can be prevented. In addition, the amount of water supplied to the water sprayer can be easily adjusted according to the material of the mat and the type of seeds by adjusting valves and the like.

The seeds can be pressed into the mat and buried in the mat by pressing sequentially. (13) Since the roller driving unit is connected to the conveying belt driving roller of the conveying device, the driving of the press can be started simultaneously with the driving of the conveying device, and an independent motor or the like is used as the roller driving unit. The number of parts of the seed mat manufacturing apparatus can be reduced without the need. (14) Since the conveyor belt driving roller and the roller driving unit of the conveyor are connected by a sprocket and a chain, the rotation speed of the press roller can be changed only by replacing the sprocket. Since the rotation speed is set to be 1 to 2 times the conveying speed of the conveying belt, the mat can be smoothly supplied between the conveying belt and the press roller. (15) Since the space between the conveyor belt and the press roller is smaller than the thickness of the mat, the entire seeds can be buried on the surface of the mat, and the surface of the mat can be evenly flattened. It is possible to prevent the seeds from falling off from the seed mat when the stored seed mats are stacked and stored. (16) When a mat of a plate-like body made of a phenolic resin foam is used as the mat, seeds sowed on the surface of the mat can be easily buried with a press machine, and seeds having the entire seed buried on the surface can be buried. The mat can be easily manufactured, and since the mat is lightweight, the mat and the seed mat are excellent in transportability. (17) Since the mat is made of the resin foam, the cells (bubbles) of the resin foam are easily broken by the press-fitting of the seeds, so that the seeds can be embedded in the mat without damaging the seeds. The seeds can be held in the holes in which the seeds are embedded by the elastic force of the cells and the hairs on the surface of the seeds. (18) Since the mat is compressed by a press machine, the overall strength of the mat can be increased, the mat surface can be prevented from becoming fluffy and tattered, and the thickness of the mat can be reduced. In addition, workability during storage and transportation can be improved. (19) Since the sensor section is provided on the upstream side of the water sprayer and on the upstream side of the adhesive supply apparatus, the sensor section detects that the mat has been conveyed to each device, and starts driving each device. This makes it possible to constantly discharge water and adhesive onto the transfer surface of the transfer device, and thus is excellent in energy saving, usability, and economy.
