本考案は、播種後や洗浄後の育苗箱を自動的に所定段数積重ねる装置の改良技 術に関する。 The present invention relates to an improved technique of a device for automatically stacking a predetermined number of seedling raising boxes after sowing or washing.
【０００２】[0002]
従来、この種の育苗箱積重ね装置としては、特開昭６１−２２７７１４号公報 で示されたものが知られている。これは、搬送されたきた育苗箱をエアーシリン ダで押上げることで下方から順次積上げていく手段であり、押上げられた育苗箱 をその押上げ位置において保持する支持機構がチェーンコンベヤの上方位置に配 設してある。 Conventionally, as a seedling raising box stacking device of this type, a device shown in Japanese Patent Laid-Open No. 61-227714 is known. This is a means to stack the transported nursery boxes one after another by pushing them up with an air cylinder, and the support mechanism that holds the pushed nursery boxes at the pushing position is located above the chain conveyor. It is located in

上記の育苗箱積重ね装置では、搬送されてくる育苗箱をリフト機構部位の所定 位置で停止させてから積重ね作動が開始されるのであるが、前記従来技術では、 単に育苗箱を所定位置で停止させるというものであり、播種後の育苗箱を単に停 止させると慣性による停止ショックによって土や種が不用意に動いてしまうおそ れが強い。 本考案の目的は、上記停止ショックを極力無くすことによって播種状態に悪影 響を及ぼすことなく積重ね作動に移行できるようにする点にある。 In the above-mentioned nursery box stacking device, the stacking operation is started after the conveyed nursery box is stopped at a predetermined position of the lift mechanism part.However, in the above-mentioned conventional technique, the nursery box is simply stopped at a predetermined position. Therefore, if the nursery box after sowing is simply stopped, it is likely that the soil and seed will move carelessly due to a stop shock due to inertia. An object of the present invention is to eliminate the above-mentioned stop shock as much as possible so that the operation can be shifted to the stacking operation without adversely affecting the seeding state.

上記目的の達成のために本考案は、搬送コンベヤによって積上げ位置に搬送さ れてきた重積み自在な育苗箱を一定量上方に押上げるリフト機構と、このリフト 機構によって押上げられた育苗箱をその押上げられた位置で保持する支持機構と を備え、支持機構で保持される育苗箱をリフト機構の育苗箱押上げ作動によって 下層の育苗箱から順次積上げていく積上げ作動を繰り返すとともに、支持機構で 保持される育苗箱が所定段数に達するとリフト機構の作動が停止する状態に、支 持機構に保持された育苗箱の段数を検出する段数検出センサと、支持機構とリフ ト機構とを連係させる制御手段を設け、更に、搬送コンベヤによって搬送される 育苗箱が、積上げ位置から育苗箱搬送方向上手側に若干間隔離れた積上げ位置近 傍地点に到達したことを検出するセンサを装備し、このセンサが検出作動すると 搬送コンベヤの搬送速度を漸減するように、センサと搬送コンベヤの駆動部とを 連係する制御手段を備えてあることを特徴とする。 In order to achieve the above object, the present invention provides a lift mechanism that pushes upward a certain amount of stackable seedling raising boxes that have been conveyed to the stacking position by a conveyer conveyor, and a seedling raising box that is pushed up by this lift mechanism. With the support mechanism that holds the raised seedlings, the raising mechanism repeatedly pushes the seedling raising boxes that are held by the support mechanism to push up the seedling raising boxes from the lower layer. When the number of stages of the nursery boxes to be held by the robot reaches a predetermined number, the lift mechanism stops operating, and the stage number detection sensor that detects the number of stages of the nursery boxes held by the support mechanism is linked to the support mechanism and the lift mechanism. In addition, a control means is provided to allow the nursery boxes to be transported by the transport conveyor to reach a point near the stacking position, which is slightly separated from the stacking position to the upper side in the transport direction of the nursery boxes. Equipped with a sensor for detecting that, to gradually decrease the conveying speed of the conveyor the sensor detects actuation, characterized in that are provided with a control means for linking the driving of the sensor and the conveyor.

つまり、積上げ位置の手前で育苗箱の搬送速度が減速されて徐々に速度を落と しながら停止するようになり、慣性による停止ショックを減少させることができ るとともに、積上げ位置近傍地点に到達したことを検出するセンサと搬送コンベ ヤの駆動部とを連係する制御手段により、その減速制御が自動的に、かつ、必要 となる場合にのみ行われるようになる。 In other words, the transport speed of the nursery box is slowed down before the stacking position and gradually stops to stop, which can reduce the stop shock due to inertia and reach the point near the stacking position. The deceleration control is automatically performed only when necessary by the control means that links the sensor for detecting the speed and the drive section of the transport conveyor.
【０００６】[0006]
従って、慣性による停止ショックによって土や種が不用意に動いてしまう不都 合なく、良好な播種状態を維持したままで積上げ作動に移行できるようになる育 苗箱積重ね装置が得られた。これは、例えば、ローラコンベヤのローラの駆動回 転速度を搬送下手側のもの程遅くするとか、搬送速度は一定にしてブレーキを作 用させるといった減速手段に比べて、育苗箱に無理な外力が作用するとかスリッ プしたり、あるいは非円滑に減速されるといった作動乱れが少ない点で有利であ る。 Therefore, a seedling box stacking device was obtained in which soil and seeds could be inadvertently moved by a stop shock due to inertia, and the operation could be switched to stacking while maintaining a good seeding condition. This is because, for example, compared to deceleration means such as lowering the driving speed of the roller of the roller conveyor on the lower side of the conveyance, or applying a brake while keeping the conveyance speed constant, an excessive external force is applied to the nursery box. It is advantageous in that there is little operational disturbance such as acting, slipping, or non-smooth deceleration.

Fig. 1 shows an overall view of a seedling raising box stacking device for stacking a prescribed number (30) of seedling raising boxes 1 after being seeded at a seedling raising plant, etc. A stacking device 4 that pushes up 1 and sequentially stacks the stacks from below, 4 is a trolley for carrying the stacked seedling raising group 1A and carrying it to a subsequent process such as a germination room. As shown in FIGS. 4 and 5, the transfer conveyor 2 is composed of first to fourth transfer sections 2a, 2b, 2c, 2d from the upper side in the transfer direction of the nursery box, each of which has its own electric motor 5. And a large number of rotating rollers 6 so that they can be independently driven. The transport conveyor 2 adopts the same drive structure for the first to third transport units 2a, 2b and 2c. The structure of the second transport unit 2b will be described below. As shown in FIG. A chain interlocking mechanism 8 is used to interlock roller units 6 each having a shaft 6a attached to a support shaft 7, and one of the support shafts 7 is provided with an input sprocket 9 and an electric motor 5 at the opposite end of the chain interlocking mechanism 8. And are linked to the chain. As shown in FIGS. 5 and 6, the fourth transport unit 2d includes a slide base 36 that is movable in a direction orthogonal to the transport direction by a pair of rails 34, 34, an electric motor 5, and a roller unit 6. It is configured to have a drive part having the same structure as the first to third transfer parts, and functions to load the seedling raising group 1A on the dolly 4 by the forward and backward movement of the slide table itself and the lateral movement by the roller unit 6. The trolley 4 carries a total of 4 sets of seedling raising box groups 1A stacked in 30 stages in the front, rear, left and right, and transports them. Pack 1A of boxes and then carry it to the germination room. As shown in FIG. 13, the nursery box 1 is a resin molded product, and the bottom surface 1a is a transfer surface on which the roller unit 6 of the conveyor 2 is mounted, and a plurality of reinforcing ribs 1b are provided on the carrying section for carrying. 1c is formed on each of the front and rear ends of the side wall. Due to the structure in which the lower end edge of the reinforcing rib 1b on the side wall is located slightly above the bottom surface 1a, the seedling raising box 1 is formed in a stackable shape with upper and lower overlapping portions.
【０００８】 図３、図４に示すように、第２搬送部（搬送コンベヤに相当）２ｂは、第１搬 送部２ａからの育苗箱１を後述する積層装置３における昇降台１８の押上げに適 した積上げ位置に搬送させるものであり、その積上げ位置で育苗箱を停止ショッ クなく減速して停止させる自動減速制御回路Ｃが組込まれている。すなわち、積 上げ位置から育苗箱搬送方向上手側に若干間隔離れた積上げ位置近傍地点に到達 したことを検出する通過検出センサ（接触式のリミットスイッチや光学式センサ 等）３７を装備し、この通過検出センサ３７が検出作動すると第２搬送部２ｂの 搬送速度を漸減するように、通過検出センサ３７と第２搬送部２ｂの電動モータ ５とを連係する制御装置（第２制御手段３８に相当）２８を設けて自動減速制御 回路Ｃが構成されている。 つまり、育苗箱１が通過検出センサ３４に到達すると電動モータ５の回転速度 が漸減されるように制御され、育苗箱１は慣性による停止ショックなく滑らかに 積上げ位置で停止するようになるのである。As shown in FIGS. 3 and 4, the second transfer section (corresponding to a transfer conveyor) 2b pushes up the raising / lowering table 18 in the laminating apparatus 3 described later from the first transfer section 2a. The automatic deceleration control circuit C is installed to move the nursery box to the appropriate stacking position and decelerate and stop it without stopping at that stacking position. That is, a passage detection sensor (contact type limit switch, optical sensor, etc.) 37 is installed to detect when a point near the stacking position, which is slightly spaced from the stacking position to the upper side in the transport direction of the nursery box, is reached. A control device (corresponding to the second control means 38) that links the passage detection sensor 37 and the electric motor 5 of the second transport unit 2b so that the transport speed of the second transport unit 2b is gradually decreased when the detection sensor 37 performs the detection operation. 28, the automatic deceleration control circuit C is configured. That is, when the nursery box 1 reaches the passage detection sensor 34, the rotation speed of the electric motor 5 is controlled to be gradually reduced, and the nursery box 1 is smoothly stopped at the stacking position without a stop shock due to inertia.
【０００９】 次に、積層装置３の構造について説明する。 図３、図４、及び図７に示すように、積層装置３は、所定位置に搬送されてき た育苗箱１を一定量上方に押上げるリフト機構１０と、このリフト機構１０によ って押上げられた育苗箱１をその押上げられた位置で保持する支持機構１１とか ら構成されている。 支持機構１１は、電動シリンダ（駆動手段に相当）１３による水平方向のスラ イド移動により育苗箱１の左右側壁の載置部１ｃに対して同時に出退自在な一対 の長尺形状の係合片１２（図１３参照）で構成（揺動移動により出退自在な係合 片１２でも良い）され、係合片１２が育苗箱１側に突出した受止め姿勢（図７の 状態）にあるとこれら突出係合片１２に載置部１ｃを載せ付けるることで育苗箱 １を載付け支持可能であり、かつ、係合片１２が外方に移動して退入した非作用 姿勢にあると育苗箱１の上下方向の移動を許容する状態に係合片１２の出退移動 量を設定してある。電動モータ１４とネジ送り機構１５とで構成される電動シリ ンダ１３に代えて油圧シリンダやソレノイドを用いるものでも良い。 リフト機構１０は、３個の作用突起１７（図３中における最右端のものは次の 育苗箱の進行を阻止するストッパである）を取付けた昇降台１８とこの昇降台１ ８を昇降操作する回転カム１９とギヤードモータ２０とで構成されている。作用 突起１７はローラユニット６間に配置され、昇降台１８の中央部分に回転カム１ ９に追従接触するベアリング２１が支承されるとともに、昇降台１８の前後には 昇降移動軌跡を決定するガイド機構２２が備えてある。ガイド機構２２は、図９ に示すように、コンベヤフレーム２３に支持される筒軸２４に昇降台１８に取付 けられたガイド軸２５を内嵌し、ガイド軸２５下端の受け板２５ａとコンベヤフ レーム２３側との間に圧縮バネ２６を介装して構成されている。つまり、昇降台 １８は前後のバネ２６，２６によって下降付勢されることでベアリング２１が回 転カム１９に追従するようにしてある。尚、１８ａはローラ６との干渉を避ける 逃げ孔である。 回転カム１９には、複数の検出片Ｋ1 〜Ｋ5 がボルト止めしてあるとともに、 コンベヤフレーム２３には前記検出片Ｋ1 〜Ｋ5 の通過によって作動するセンサ （光学式センサ等）２７が取付けてあり、その検出センサ２７とギヤードモータ ２０と第１乃至第３搬送部２ａ，２ｂ，２ｃの計３個の電動モータ５と一対の電 動シリンダ１３と後述する感知センサ２９、ソレノイド３０、リミットスイッチ ３１、及び接触スイッチ３３、更に前述した通過検出スイッチ３７とを制御装置 ２８に接続して図２に示す自動積層制御回路Ａが構成してある。Next, the structure of the laminating apparatus 3 will be described. As shown in FIG. 3, FIG. 4, and FIG. 7, the stacking device 3 includes a lift mechanism 10 that pushes up the nursery box 1 that has been transported to a predetermined position by a certain amount, and a lift mechanism 10 that pushes the lift mechanism 10. It comprises a support mechanism 11 for holding the raised seedling raising box 1 in its pushed up position. The support mechanism 11 is a pair of long engagement pieces that can be simultaneously withdrawn from / removed from the mounting portions 1c on the left and right sidewalls of the nursery box 1 by horizontal slide movement by an electric cylinder (corresponding to driving means) 13. 12 (see FIG. 13) (the engaging piece 12 may be retractable by swinging movement may be used), and the engaging piece 12 is in the receiving posture (state of FIG. 7) protruding toward the nursery box 1 side. By mounting the placing portion 1c on these protruding engagement pieces 12, the seedling raising box 1 can be placed and supported, and the engagement pieces 12 move outward and are in a non-working posture. The moving amount of the engaging piece 12 is set in a state where the vertical movement of the nursery box 1 is allowed. A hydraulic cylinder or a solenoid may be used instead of the electric cylinder 13 composed of the electric motor 14 and the screw feed mechanism 15. The lift mechanism 10 lifts and lowers the lift 18 and the lift 18 to which the three action protrusions 17 (the rightmost one in FIG. 3 is a stopper that prevents the next seedling box from advancing). It is composed of a rotary cam 19 and a geared motor 20. The protrusions 17 are arranged between the roller units 6, a bearing 21 that follows and contacts the rotating cam 19 is supported in the central portion of the lifting table 18, and a guide mechanism that determines the lifting movement trajectory before and after the lifting table 18. 22 is provided. As shown in FIG. 9, the guide mechanism 22 has a cylindrical shaft 24 supported by a conveyor frame 23 and a guide shaft 25 attached to the lifting table 18 fitted therein, and a receiving plate 25a at the lower end of the guide shaft 25 and the conveyor frame. The compression spring 26 is interposed between the No. 23 side and the No. 23 side. That is, the lifting table 18 is urged downward by the front and rear springs 26, 26 so that the bearing 21 follows the rotating cam 19. Incidentally, 18a is an escape hole for avoiding interference with the roller 6. A plurality of detection pieces K 1 to K 5 are bolted to the rotary cam 19, and a sensor (optical sensor or the like) 27 that operates by the passage of the detection pieces K 1 to K 5 is provided on the conveyor frame 23.

The limit switch 31, the contact switch 33, and the passage detection switch 37 described above are connected to the control device 28 to form an automatic stacking control circuit A shown in FIG.
【００１０】 次に、積層装置３の作用を説明する。 図９に示すように、第２搬送部２ｂの終端にはソレノイド３０の伸縮によって 左右軸心Ｐ周りで揺動移動自在なアーム３５の先端に接触式の育苗箱感知センサ ２９が設けてあり、搬送育苗箱１が感知センサ２９に接当すると第２搬送部１ｂ の電動モータ５が停止するとともに、ギヤードモータ２０が起動されて回転カム １９が回転し始める。そして、0.14秒かかって育苗箱１が第１所定高さ（14.5mm ）上昇すると第２検出片Ｋ2 によって検出センサ２７が作動し（図１０の状態） 、それによって電動シリンダ１３が作動して左右の係合片１２が受止め姿勢から 非作用姿勢に0.12秒かかって移動するとともに、第２検出片Ｋ2 の検出から第３ 検出片Ｋ3 を検出するまでの0.17秒間は回転カム１９のベアリング２１との接触 半径が一定であり育苗箱１は第１所定高さに維持される。第１所定高さは押上げ 育苗箱１が上側の育苗箱１の下端に接当する高さ（12.5mm）よりも少し高いめに 設定してある。 第３検出片Ｋ3 によって検出センサ２７が作動すると、電動シリンダ１３が停 止されるとともに回転カム１９によって再び昇降台１８の上昇が始まり、0.42秒 かかって第４検出片Ｋ4 が検出センサ２７に到達する（図１１の状態）と昇降台 １８が第２所定高さである上限迄上昇（50mm）するとともに電動シリンダ１３が 作動して係合片１２が非作用姿勢から受止め姿勢に0.12秒かかって移動し、更に 、第５検出片Ｋ5 を検出するまでの0.16秒間は回転カム１９のベアリング２１と の接触半径が一定であり育苗箱１は第２所定高さに維持される。 第５検出片Ｋ5 によって検出センサ２７が作動すると、電動シリンダ１３が停 止されるとともに回転カム１９によって昇降台１８の下降が始まる状態になる。 そして、0.71秒かかって第１検出片Ｋ1 が検出センサ２７部位に達する元の状態 （図９の状態）に戻ると昇降台１８も元の高さに下降し、かつ、ギヤードモータ ２０が停止し、次に来る育苗箱１によって感知センサ２９が作動するまでギヤー ドモータ２０の停止状態が維持される。又、第２搬送部２ｂの電動モータ５は感 知センサ２９が作動してから第５検出片Ｋ5 が検出センサ２７部位に達するまで は停止され、それ以外の間は駆動されるのである。Next, the operation of the laminating apparatus 3 will be described. As shown in FIG. 9, a contact-type nursery box detection sensor 29 is provided at the end of the arm 35 that is swingable about the left and right axis P by the expansion and contraction of the solenoid 30 at the end of the second transport unit 2b. When the transport nursery box 1 comes into contact with the sensor 29, the electric motor 5 of the second transport section 1b stops, the geared motor 20 is activated, and the rotary cam 19 starts to rotate. Then, when it takes 0.14 seconds to raise the seedling raising box 1 by the first predetermined height (14.5 mm), the detection sensor 27 is activated by the second detection piece K 2 (state of FIG. 10), and thereby the electric cylinder 13 is activated. The left and right engaging pieces 12 move from the receiving posture to the non-acting posture in 0.12 seconds, and the rotary cam 19 moves for 0.17 seconds from the detection of the second detection piece K 2 to the detection of the third detection piece K 3 . The contact radius with the bearing 21 is constant and the nursery box 1 is maintained at the first predetermined height. The first predetermined height is set to be slightly higher than the height (12.5 mm) at which the raising seedling raising box 1 contacts the lower end of the upper raising seedling raising box 1. When the detection sensor 27 is actuated by the third detection piece K 3 , the electric cylinder 13 is stopped, and the lifting table 18 starts to rise again by the rotating cam 19, and it takes 0.42 seconds for the fourth detection piece K 4 to detect the detection sensor 27. 11 (state of FIG. 11), the lift 18 moves up to the upper limit of the second predetermined height (50 mm), the electric cylinder 13 operates, and the engaging piece 12 moves from the non-acting position to the receiving position by 0.12. It takes a second to move, and the radius of contact with the bearing 21 of the rotary cam 19 is constant for 0.16 seconds until the fifth detection piece K 5 is detected, and the nursery box 1 is maintained at the second predetermined height. When the detection sensor 27 is actuated by the fifth detection piece K 5 , the electric cylinder 13 is stopped and the rotary cam 19 starts the descent of the lift table 18. Then, when it takes 0.71 seconds to return to the original state where the first detection piece K 1 reaches the detection sensor 27 portion (the state shown in FIG. 9), the elevating table 18 also descends to its original height, and the geared motor 20 stops. Then, the stopped state of the geared motor 20 is maintained until the detection sensor 29 is activated by the next seedling raising box 1. The electric motor 5 of the second conveying portion 2b from working-sensitive knowledge sensor 29 to the fifth detection piece K 5 reaches the detecting sensor 27 site is stopped, while the other is being driven.

Then, the lifting table 18 is raised to the first predetermined height, the engaging piece 12 is operated to the non-acting position, the solenoid 30 is contracted and the arm 35 is lowered, and the raising box 18 is temporarily moved. Is placed on the lift table 18, then the lift table 18 descends and the nursery box group 1A is transported to the carriage 4 by the second to fourth transport sections 2b, 2c, 2d. As shown in FIGS. 3 and 4, a limit switch 31 for detecting passage of the seedling raising box 1 is provided at the third carrying section 2c, and the limit switch 31 operates in accordance with passage of the seedling raising box group 1A.
