【発明の詳細な説明】 〔産業上の利用分野〕 本発明は育苗箱の積重ね装置に関し、詳しくは、積重ね
育苗を行うため、播種処理後の育苗箱を積重ねるための
装置に関するものである。Description: TECHNICAL FIELD The present invention relates to a stacking apparatus for seedling raising boxes, and more particularly to a device for stacking seedling raising boxes after sowing treatment for carrying out stacked seedling raising.
従来、積重ね育苗を行うため、播種処理後の育苗箱を積
重ねるための装置としては、特開昭63−71025号公報に
示されるものが存在し、この引例では、連続的に送られ
る育苗箱を水平姿勢のまま棚状に保持して持ち上げ、こ
のように持ち上げることで所定のレベルに達した育苗箱
を、水平姿勢のまま横方向に送り所定の位置で連続的に
積み上げように構成されている。Conventionally, for performing stacked seedling raising, as a device for stacking seedling raising boxes after seeding treatment, there is one shown in JP-A-63-71025, and in this reference, the seedling raising boxes are continuously sent. It is configured to hold and raise in a horizontal position in a shelf shape, and to raise the seedling raising box that has reached a predetermined level by lifting in this way, and horizontally feed it in a horizontal position to continuously stack at a predetermined position. There is.
又、積重ね育苗を行う際には、前記引例の装置を用いず
に、人手による作業によって播種処理後の育苗箱を積重
ねることもある。Further, when carrying out stacked seedling raising, the seedling raising boxes after the seeding treatment may be stacked manually without using the apparatus of the above-mentioned reference.
しかし、人手による作業によって育苗箱の積重ねを行う
場合には、播種ラインからコンベア等を介して送り出さ
れる育苗箱を１枚ずつ取り上げトロッコ等に連続的に載
置するという作業形態になることから作業者は頻繁に体
を動かさねばならず、作業が煩わしいものとなる。However, when stacking seedling raising boxes by manual work, the work form is such that the seedling raising boxes sent out from the seeding line via a conveyor etc. are picked up one by one and placed continuously on a trolley, etc. The person has to move his body frequently, which makes the work troublesome.
尚、積重ね育苗を行う場合にトロッコ等に載置される育
苗箱の積重ね枚数は30程度である。In addition, when carrying out stacked seedling raising, the number of seedling raising boxes placed on a truck etc. is about 30.
又、前記引例の装置を用いて育苗箱の積重ねを行う場合
は、この装置が育苗箱を水平姿勢のまま棚状に持ち上げ
る構造であるため、装置に送り込まれる育苗箱は、その
送りを停止させた後に持ち上げられることになる。Further, when stacking the nursery boxes using the device of the above-mentioned reference, since this device has a structure of lifting the nursery boxes in a shelf shape in a horizontal posture, the nursery boxes fed to the device should stop the feeding. Will be lifted.
このことは、育苗箱を送り込んだ後には、この育苗箱が
持ち上げられるまで、次の育苗箱を送り込むことが不能
であることを意味し、この装置においては高速の積重ね
処理を行い難い構造となっている。This means that after feeding the nursery box, it is impossible to feed the next nursery box until this nursery box is lifted, and this device makes it difficult to perform high-speed stacking processing. ing.
因みに、処理量を増すために、この装置に対して高速で
育苗箱を送り込んだ場合には、その送りを停止させた際
に、育苗箱の床土に偏りを生じ、植付けに不適当な苗と
なる。By the way, when a nursery box was sent to this device at a high speed to increase the throughput, when the feeding was stopped, the soil of the nursery box became uneven and the seedlings unsuitable for planting. Becomes
本発明の目的は、人手による積重ね作業を行う際には作
業者が行う動作の量を低減し、又、引例の如き積重ね装
置を用いる際には、育苗箱の送り込み速度を高めること
無く、積重ね処理枚数の増大を図り得る装置を合理的に
構成する点にある。An object of the present invention is to reduce the amount of operation performed by a worker when performing a manual stacking work, and when using a stacking device as in the reference, stacking without raising the feeding speed of the nursery box. The point is to reasonably configure an apparatus capable of increasing the number of processed sheets.

いて、育苗箱を受け止める側の育苗箱が、搬送装置に対
して相対的に搬送方向の上手側に向けて滑動できるよ
う、前記搬送装置を構成して成る点にあり、その作用、
及び、効果は次の通りである。A feature of the present invention is that the seedling raising seedlings are placed above the seedling raising seedling box by detecting that the seedling raising seedlings are placed and continuously conveyed in a horizontal direction, and that the seedling raising box sent by this feeder reaches a predetermined position. Lifting means for lifting and holding the seedling raising box, and in the state where the seedling raising box is lifted and held by this lifting means, it is detected that the next seedling raising box is sent to a position substantially below this seedling raising box, and the seedling raising box in the lifted state is detected. A stacking system of nursery boxes is configured with the descending means for lowering, and when the nursery boxes are lowered, the nursery box on the side receiving the nursery boxes slides relative to the transport device toward the upper side in the transport direction. In order to be able to do so, there is the point that it is configured by the above-mentioned transfer device, its action,
And, the effects are as follows.
上記特徴を例えば第１図乃至第５図に示すように構成す
ると、搬送装置（17）に送られる育苗箱（１）は持ち上
げ手段（Ｅ）によって持ち上げた後、降下手段（Ｆ）に
よって次の育苗箱（１）の上面に重ねられることにな
り、この降下時には横方向への移動が停止した状態の育
苗箱（１）が移動状態の育苗箱（１）の上面に重なるた
め移動状態の育苗箱（１）（受け止める側の育苗箱
（１））には搬送装置（17）の搬送方向の上手側に向け
て力が作用するが、搬送装置（17）が育苗箱（１）の滑
動を許すため、換言すると移動の遅れを許すため、搬送
方向の上手側に向かう力が作用した場合には、夫々の育
苗箱（１），（１）を作用する衝撃は柔げられることに
なる。When the above features are configured as shown in, for example, FIGS. 1 to 5, the seedling raising box (1) sent to the transfer device (17) is lifted by the lifting means (E) and then moved by the descending means (F) to the next position. Since the seedling raising box (1) will be stacked on the upper surface of the raising seedling box (1) and the lateral movement of the raising seedling box (1) will overlap with the upper surface of the moving seedling raising box (1) during this descent, A force acts on the box (1) (the receiving side nursery box (1)) toward the upper side in the transport direction of the carrier device (17), but the carrier device (17) slides the nursery box (1). In order to allow, in other words, to delay the movement, when the force acting toward the upper side in the carrying direction acts, the impact acting on each seedling raising box (1), (1) is softened.
つまり、この装置は連続的に送られる育苗箱を、二段に
積重ねて送り出すので、人手による積重ね作業を行う場
合には、この装置を播種ラインの後の搬送系に介装する
だけで作業者は二枚の育苗箱（１），（１）を一度に扱
えることになり、又、引例に示される如き積重ね装置を
用いる場合も搬送系に当該装置を介装するだけで、二枚
の育苗箱（１），（１）を一度に棚状に持ち上げ得るこ
とになり、しかも、この装置では移動状態の育苗箱
（１）に対して育苗箱（１）を重ねる構造であるにも拘
らず、床土を偏らせること無く連続した作業を行えるの
である。In other words, since this equipment stacks and feeds the nursery boxes that are continuously sent in two stages, when performing manual stacking work, the operator only needs to install this equipment in the transport system after the seeding line. Means that two seedling raising boxes (1), (1) can be handled at one time, and even if a stacking device as shown in the reference is used, it is only necessary to insert the device into the transport system. The boxes (1), (1) can be lifted up like a shelf at a time, and this device has a structure in which the seedling raising box (1) is stacked on the moving seedling raising box (1). The continuous work can be performed without biasing the soil.
従って、人手による積重ね作業を行う際には、作業者が
行う動作の量を低減し、又、育苗箱を棚状に持ち上げる
積重ね装置を用いる際には、育苗箱の送り込み速度を高
めること無く、積重ね枚数の増大を図り得る装置が合理
的に構成されたのである。Therefore, when performing a stacking work by hand, reduce the amount of movements performed by the worker, and when using a stacking device that lifts the nursery box in a shelf shape, without increasing the feeding speed of the nursery box, A device that can increase the number of stacked sheets was reasonably constructed.
以下、本発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
