【発明の属する技術分野】
本発明は、固体の充填された容器をコンベアで搬送する際に、容器中の固体の均平化を図る装置に関するものであり、特に、ポットへ供給された育苗養土の均平化を図る養土均平装置に関する。
【0002】
【従来の技術】
一般の播種プラントでは、コンベアで搬送中のポットに養土充填・播種・覆土が行われて一工程を成す。
このうち養土充填の工程で、ホッパーからポットに供給された養土の表面を均平にするためには、従来、養土の盛り上がり部分にブラシ等を当てがって擦り切ることによって均平化していた。 この方法によると、ブラシがポットに当たることによって、ポットの変形等が起こる不都合があった。また、ポットへ供給する養土の必要量が容器の容量に比べて少ない場合、ポットの側壁が障害となってブラシをポット中へ十分装入できず養土の表面を均平化することは不可能であった。
【0003】
【発明が解決しようとする課題】
本発明は従来技術の有する上記問題点に鑑みてなされたものであり、その目的は、仮にポットへ供給する養土の必要量が容器の容量に比べて少ない場合にも、養土の表面を常に均平化できる養土均平装置を得ることである。
【0004】
【課題を解決するための手段】
上記目的を達成するために、本発明の養土均平装置は、ポットに養土を供給した後のコンベアにおいて、搬送されるトレイの幅方向両側部に接するようにコンベアの両側部に配設され、かつ、コンベアの進行方向に振動するトレイガイドを備えるものである。
【0005】
【発明の実施の形態】
本発明の実施例を図面に基づいて説明する。
図1は、本発明装置の要部を示す上部平面図である。
多数の育苗ポット(11)を備えた育苗トレイ(10)は、この図の座標系において左から右へ流れるベルトコンベア(20)上を搬送される。
この育苗トレイ(10)の幅方向両側部に接するように、コンベア(20)両側部にトレイガイド(40)が配設されている。トレイガイド(40)は、後述の振動機構によってコンベア(20)の進行方向に振動する。
この振動により、育苗ポット(11)に供給された養土が均平化されると同時に、育苗トレイ(10)とトレイガイド(40)との接触に起因するトレイ詰まりが防止される。
【0006】
トレイガイド(40)には、2本の支持板バネ(42)と1本の振動板バネ(41)が連結されている。この3本のバネの合力によって、トレイガイド(40)がコンベア(20)の進行方向に振動する。
2本の支持板バネ(42)は各々、コンベア(20)進行方向におけるトレイガイド(40)のほぼ上流端及び下流端と固定部材(33)との間で連結され、これら2本の支持板バネ(42)と、トレイガイド(40)、固定部材(33)とで、水平面において平行四辺形状を成すように配置される。
固定部材(33)は、これと連結した支持板(32)とネジ(31)を介して土台(30)に固定されている。
【0007】
振動板バネ(41)は、トレイガイド(40)とはこのほぼ中心で連結され、支持板バネ(42)と垂直かつ水平に配置される。振動板バネ(41)の他端は、固定部材(33)に設けられた振動発生部(A)につながっている。
振動発生部(A)は、土台(30)に設置されたモーター(45)からの動力によって、振動板バネ(41)を伸縮させるものである。
このように、振動板バネ(41)は、その設置された位置のまま伸縮するが、これと垂直に設置されている支持板バネ(42)の復元力による規制によって、トレイガイド(40)はコンベア(20)の進行方向に振動する。
【0008】
振動発生部(A)の振動駆動方法は、例えば図2に示すように、円盤状の振動用部材(43)を偏心軸(44)回りに回転させることによって、振動板バネ(41)を伸縮させる。ここで、振動板バネ(41)は、固定された管状のバネガイド(46)を通るので、振動板バネ(41)はその設置された位置のまま伸縮することになる。
また、図3に示すように、振動用部材(43)を六角軸とし、これに摺動するよう配設されたワイヤー(41b)の環にバネ(41a)を連結し、固定された管状のバネガイド(46a)に通す構成にすることによって振動発生部(A)を振動駆動させてもよい。
或いは、図4に示すように、円盤状の振動用部材(43)上に、棒状のバネ係止軸(47)を凸設させ、これに摺動するよう配設されたワイヤー(41b)の環にバネ(41a)を連結し固定されたバネガイド(46b)に通してピストンクランク機構に準じる構成にすることによって振動発生部(A)を振動駆動させてもよい。なお、バネガイド(46b)は図示のように凸設された2本の軸棒で構成してもよい。
【0009】
他方、振動発生部(A)の動力源であるモーター(45)の回転速度を調節可能な構成にすると、トレイガイド(40)の振動周期を適宜調節して各種育苗ポット(11)の状態に対応させることができ均平化が容易になる。
【0010】
また、ネジ(31)を通す支持板(32)の穴を長穴とし、モーター(45)の固定部位も同様にすることによって、土台(30)に対して固定部材(33)が、コンベア(20)の幅方向に移動可能な構成にすると、2基のトレイガイド(40)の間隔を調節できようになるので、各種育苗トレイ(10)の大きさに対応することができる。
なお、本発明の構成は、本発明の主旨から逸脱しない限り適宜設計変更可能なものである。
【0011】
【発明の効果】
本発明は、以上のような構成をしているので、仮に育苗ポットへ供給する養土の必要量が容器の容量に比べて少ない場合にも、常に育苗ポットを変形させることなく養土の表面を均平化できる効果を有する。
また、コンベアの進行方向へ育苗トレイを振動させるので、育苗トレイがコンベア上で詰まることを防止できる。
更に、振動発生部の動力源であるモーターの回転速度を可変とすることで、振動周期を適宜調節して各種育苗ポットの状態に対応させることができ、土台に対して固定部材をコンベアの幅方向に移動可能な構成にして、2基のトレイガイドの間隔を可変とすることで、各種育苗トレイの大きさに対応することができる効果もある。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for leveling a solid in a container when the container filled with the solid is conveyed by a conveyor, and in particular, leveling of seedling culture soil supplied to a pot is achieved. It is related to soil leveling equipment.
[0002]
[Prior art]
In a general sowing plant, soil filling, sowing, and covering are carried out in a pot that is being conveyed by a conveyor to form one process.
In order to level the surface of the soil supplied from the hopper to the pot in the soil filling process, it has been conventionally done by applying a brush or the like to the swelled portion of the soil and scraping it off. It was converted. According to this method, there is a disadvantage that the deformation of the pot occurs when the brush hits the pot. In addition, if the required amount of soil to be supplied to the pot is small compared to the capacity of the container, the side wall of the pot becomes an obstacle and the brush cannot be fully charged into the pot, so that the surface of the soil can be leveled. It was impossible.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned problems of the prior art, and the purpose of the present invention is to provide a surface of the soil nodule even when the amount of soil to be supplied to the pot is small compared to the capacity of the container. It is to obtain a soil leveling device that can always level.
[0004]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the soil leveling apparatus of the present invention is arranged on both sides of the conveyor so as to contact both sides of the tray in the width direction of the tray to be conveyed in the conveyor after supplying the soil to the pot. And a tray guide that vibrates in the traveling direction of the conveyor.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an upper plan view showing a main part of the device of the present invention.
A seedling tray (10) having a large number of seedling pots (11) is conveyed on a belt conveyor (20) that flows from left to right in the coordinate system of this figure.
Tray guides (40) are disposed on both sides of the conveyor (20) so as to contact both sides of the seedling tray (10) in the width direction. The tray guide (40) vibrates in the traveling direction of the conveyor (20) by a vibration mechanism described later.
By this vibration, the soil fed to the seedling pot (11) is leveled, and at the same time, the tray clogging caused by the contact between the seedling tray (10) and the tray guide (40) is prevented.
[0006]
Two support plate springs (42) and one vibration plate spring (41) are connected to the tray guide (40). The tray guide (40) vibrates in the traveling direction of the conveyor (20) by the resultant force of the three springs.
Each of the two support plate springs (42) is connected between the upstream and downstream ends of the tray guide (40) in the direction of travel of the conveyor (20) and the fixing member (33). The spring (42), the tray guide (40), and the fixing member (33) are arranged to form a parallelogram in the horizontal plane.
The fixing member (33) is fixed to the base (30) via a support plate (32) and a screw (31) connected to the fixing member (33).
[0007]
The vibration plate spring (41) is connected to the tray guide (40) at the substantially center, and is arranged vertically and horizontally with the support plate spring (42). The other end of the diaphragm spring (41) is connected to a vibration generating part (A) provided on the fixing member (33).
The vibration generating part (A) extends and contracts the diaphragm spring (41) by the power from the motor (45) installed on the base (30).
In this way, the vibration plate spring (41) expands and contracts in its installed position, but the tray guide (40) is moved by the restriction by the restoring force of the support plate spring (42) installed perpendicularly to the vibration plate spring (41). It vibrates in the direction of travel of the conveyor (20).
[0008]
For example, as shown in FIG. 2, the vibration generator (A) is driven by rotating a disc-shaped vibration member (43) about the eccentric shaft (44) to expand and contract the vibration spring (41). Let Here, since the diaphragm spring (41) passes through the fixed tubular spring guide (46), the diaphragm spring (41) expands and contracts in its installed position.
Further, as shown in FIG. 3, the vibrating member (43) is a hexagonal shaft, and a spring (41a) is connected to the ring of the wire (41b) arranged so as to slide on the hexagonal shaft. The vibration generating part (A) may be driven to vibrate by adopting a configuration in which the spring guide (46a) is passed.
Alternatively, as shown in FIG. 4, a rod-shaped spring locking shaft (47) is projected on a disk-shaped vibration member (43), and the wire (41b) arranged to slide on the rod-shaped spring locking shaft (47). The vibration generating part (A) may be driven to vibrate by passing through a spring guide (46b) fixed by connecting a spring (41a) to the ring so as to conform to the piston crank mechanism. The spring guide (46b) may be composed of two shaft rods that are projected as shown.
[0009]
On the other hand, when the rotational speed of the motor (45), which is the power source of the vibration generating part (A), is adjustable, the vibration period of the tray guide (40) is appropriately adjusted to bring the various seedling pots (11) into a state. Can be made uniform and leveling becomes easy.
[0010]
Further, by making the hole of the support plate (32) through which the screw (31) is passed a long hole and the fixing part of the motor (45) is the same, the fixing member (33) is connected to the base (30) by the conveyor ( 20), the distance between the two tray guides (40) can be adjusted, so that the size of the various seedling trays (10) can be accommodated.
The configuration of the present invention can be changed as appropriate without departing from the gist of the present invention.
[0011]
【The invention's effect】
Since the present invention is configured as described above, even if the required amount of soil to be supplied to the seedling pot is small compared to the capacity of the container, the surface of the soil without constantly deforming the seedling pot Has the effect of leveling.
Moreover, since the seedling tray is vibrated in the traveling direction of the conveyor, it is possible to prevent the seedling tray from being clogged on the conveyor.
Furthermore, by making the rotation speed of the motor, which is the power source of the vibration generating section, variable, the vibration cycle can be adjusted appropriately to correspond to the state of various seedling pots, and the fixing member can be connected to the base with the width of the conveyor. By making the structure movable in the direction and making the interval between the two tray guides variable, there is an effect that it is possible to cope with the size of various seedling trays.
