Description

本発明は、袋詰めされた穀物を計量器等から掬い取り、任意の場所へ運搬・移送するリフター装置に関するものである。   The present invention relates to a lifter device that picks up a packed grain from a measuring instrument or the like and transports / transfers it to an arbitrary place.

従来から知られているこの種の装置として、特許文献1がある。この装置は、可搬自在な台車フレームに昇降可能なリフトフォークを設け、このリフトフォークを計量器上に載置される穀粒袋の下に差し入れて計量器から穀粒袋を掬い取り、他の場所へ運搬・移送するものである。リフトフォークは、下限位置から上限位置までの範囲で昇降し、途中掬い取り位置と中間位置を検出して昇降を停止するようになっている。穀粒袋の掬い取りは、リフトフォークを下限位置にした状態で、計量器の計量台と穀粒袋との間にリフトフォークを差し入れ、計量台と袋とが擦れない掬い取り位置まで上昇させることで行われる。   Japanese Patent Application Laid-Open No. 2004-151867 is known as this type of device. This device is equipped with a lift fork that can be raised and lowered on a portable carriage frame, and this lift fork is inserted under the grain bag placed on the measuring instrument, and the grain bag is removed from the measuring instrument. It is intended to be transported and transported to other locations. The lift fork moves up and down in a range from the lower limit position to the upper limit position, and stops raising and lowering by detecting a scooping position and an intermediate position on the way. To pick up the grain bag, with the lift fork in the lower limit position, insert the lift fork between the weighing table of the measuring instrument and the grain bag and raise it to the scooping position where the weighing table and the bag do not rub. Is done.

さて、計量台の高さは計量器の種類によって異なるため、この装置ではリフトフォークの下限位置を調整できる機能を備えている。この装置における下限位置の調整は、下限位置を検出する下限スイッチが取り付けられた調節プレートを台車フレームの長穴の範囲で上下させ、任意の位置でボルトにより固定することで行われる。しかしながら、この装置では、リフトフォークの位置を計量台の高さに合わせる場合、目測によって調整プレートを移動させてからボルトで固定し、ハンドルに設けた操作ボタンで上昇(もしくは下降)キーを入力してリフトフォークを移動させるようになっているため、位置調整後に上昇(もしくは下降)キーを入力してリフトフォークを移動させたときにはじめて正式なリフトフォークの下限位置がわかることになる。これでは、リフトフォークの位置が合わなかったら、再度同じ手順で高さ調整を繰り返さなければならず、非常に面倒である。
特開2004−269146号
Now, since the height of the weighing platform differs depending on the type of weighing device, this device has a function that can adjust the lower limit position of the lift fork. Adjustment of the lower limit position in this device is performed by moving an adjustment plate, to which a lower limit switch for detecting the lower limit position is attached, up and down within the range of the long hole of the carriage frame and fixing it with a bolt at an arbitrary position. However, with this device, when adjusting the position of the lift fork to the height of the weighing platform, the adjustment plate is moved by visual inspection and then fixed with bolts, and the up (or down) key is input with the operation button provided on the handle. Since the lift fork is moved, the official lower limit position of the lift fork is known only when the lift fork is moved by inputting the up (or down) key after the position adjustment. In this case, if the position of the lift fork does not match, the height adjustment must be repeated again in the same procedure, which is very troublesome.

Hereinafter, Example 1 is demonstrated based on drawing. FIG. 1 is a front view showing a lifter of Embodiment 1, and FIG. 2 is a plan view.
Reference numeral 1 denotes a base serving as a base of a lifter, on which a support frame 2, a machine room 3, and a battery 13 are placed, and wheels 4 and 4 are attached to both side surfaces. The support frame 2 includes a lifting / lowering fork 5 that lifts and lowers the load on the front surface, and a handle 7 for moving the base 1 at the upper end. The elevating fork 5 includes a pair of left and right forks 8 that extend horizontally at the front, and includes a roller 9 that sandwiches the support frame 2 at the rear, and moves up and down along the support frame 2. The machine room 3 is equipped with an elevating motor 14 that can be rotated forward and backward for elevating the elevating fork 5 inside, and an operation panel 15 that performs power input and scooping setting on the upper surface. The wheel 4 is provided with a lock mechanism 16 on the rear wheel side so that a stable use state can be obtained. The lock mechanism 16 includes a tooth-shaped stopper plate 17 that engages with the rolling surface of the rear wheel, and a link plate 18 that displaces the stopper plate 17 between a lock position and a free position. When transporting luggage, it is used by switching to the free position. The battery 13 can be charged from a commercial power source and functions as a power source for the lifting motor 14. Reference numeral 12 denotes an operation unit provided in the vicinity of the grip portion of the handle 7 for instructing raising / lowering / stopping of the lifting / lowering fork 5.

図3は支柱フレーム2の内部構造を示す断面図であり、この図を用いて昇降フォーク5の昇降構造について説明する。
支柱フレーム2の内部には、昇降フォーク5を昇降する駆動系6が備えられている。駆動系6は、支柱フレーム2内の上部に設けられる上スプロケット10aと、下部に設けられる下スプロケット10bと、このスプロケット間に懸回されるチェーン11とからなり、チェーン11の一端を昇降フォーク5の上端、他端を昇降フォーク5の下端に連係して無端ループを形成している。下スプロケット10bには、前記昇降モータ14が連係され、該モータの正転/逆転に伴い前記駆動系6を介して昇降フォーク5が昇降可能となる。
FIG. 3 is a cross-sectional view showing the internal structure of the support frame 2, and the lifting structure of the lifting / lowering fork 5 will be described with reference to this figure.
Inside the support frame 2 is provided a drive system 6 for raising and lowering the elevating fork 5. The drive system 6 includes an upper sprocket 10a provided in the upper part of the support frame 2, a lower sprocket 10b provided in the lower part, and a chain 11 suspended between the sprockets. An endless loop is formed by linking the upper end and the other end of the upper and lower ends with the lower end of the elevating fork 5. The lower sprocket 10b is linked to the elevating motor 14, and the elevating fork 5 can be raised and lowered via the drive system 6 as the motor rotates forward / reversely.

この昇降フォーク5は、前記操作部12からの指令に基づいて任意の高さ位置に上昇/下降/停止できるようなっているのに加えて、所定の下限位置、掬い取り位置、上限位置で自動停止するようになっている。下限位置P1は、上下可動式の調整プレート24に取り付けた下限スイッチ21と中段スイッチ22が、昇降フォーク5の後部に形成したカム20により両方ともONの状態になることで検出される。掬い取り位置P2は、下限スイッチ21と中段スイッチ22が、両方ともONの状態から両方ともOFFの状態に変化することで検出される。上限位置P3は、支柱フレーム2の上部に固定された上限スイッチ23が、前記カム20によりONの状態になることで検出される。   The lifting / lowering fork 5 can be raised / lowered / stopped at an arbitrary height position based on a command from the operation unit 12 and automatically at a predetermined lower limit position, scooping position, and upper limit position. It comes to stop. The lower limit position P <b> 1 is detected when both the lower limit switch 21 and the middle switch 22 attached to the vertically movable adjustment plate 24 are turned on by the cam 20 formed at the rear part of the lifting / lowering fork 5. The scooping position P2 is detected when both the lower limit switch 21 and the middle switch 22 change from the ON state to the OFF state. The upper limit position P <b> 3 is detected when the upper limit switch 23 fixed to the upper part of the support frame 2 is turned on by the cam 20.

調整プレート24は、前記支柱フレーム2の背面に所定長さで開口した長穴25に対してハンドル付きボルト26により着脱され、ボルト26を緩めることで長穴25の範囲で上下方向に位置調整可能に配置されている。この調整プレート24を上下することにより、床面から下限位置P1及び床面から掬い取り位置P2を変更することができる。尚、下限スイッチ22と中段スイッチ23とは、所定間隔を有して調整プレート24に固定されるため、下限位置P1から掬い取り位置P2までの高さは一定に保たれる。   The adjustment plate 24 is attached to and detached from a long hole 25 opened at a predetermined length on the back surface of the support frame 2 by a bolt 26 with a handle, and can be adjusted in the vertical direction within the range of the long hole 25 by loosening the bolt 26. Is arranged. By moving the adjustment plate 24 up and down, the lower limit position P1 from the floor surface and the scooping position P2 from the floor surface can be changed. Since the lower limit switch 22 and the middle switch 23 are fixed to the adjustment plate 24 with a predetermined interval, the height from the lower limit position P1 to the scooping position P2 is kept constant.

続いて、図4を用いて実施例1の制御系について説明する。
30は制御部で、操作部12・操作パネル15・下限スイッチ21・中段スイッチ22上限スイッチ23が接続されるCPU31と、商用電源からバッテリー13に充電する充電回路32と、昇降モータ14を制御するモータ制御回路33とを備えている。操作部12には、昇降フォーク5を上昇させる上昇ボタン34と、昇降フォーク5を下降させる下降ボタン35が備えられている。尚、昇降中の昇降フォーク5を停止する場合は、上昇中/下降中に関係なく、どちらか一方のボタンを入力すればよい。操作パネル15は、電源キー36、掬い取りキー37、バッテリー残量表示部38を備えている。電源キー36を入力すると、電源が入り、各キースイッチに対応するランプが点灯するとともに、バッテリー残量に応じて表示部38が点灯する。掬い取りキー37を入力すると、前記した掬い取り位置P2での自動停止を行うか否かが切り替えられる。尚、初期状態において、掬い取りキー37はONの状態となる。
Subsequently, the control system of the first embodiment will be described with reference to FIG.
A control unit 30 controls the CPU 31 to which the operation unit 12, the operation panel 15, the lower limit switch 21, the middle switch 22 and the upper limit switch 23 are connected, the charging circuit 32 that charges the battery 13 from the commercial power source, and the lifting motor 14. And a motor control circuit 33. The operation unit 12 is provided with a raising button 34 for raising the lifting / lowering fork 5 and a lowering button 35 for lowering the lifting / lowering fork 5. In order to stop the lifting / lowering fork 5 that is being lifted / lowered, one of the buttons may be input regardless of whether the lifting / lowering fork 5 is being lifted / lowered. The operation panel 15 includes a power key 36, a scooping key 37, and a battery remaining amount display unit 38. When the power key 36 is input, the power is turned on, the lamp corresponding to each key switch is lit, and the display unit 38 is lit according to the remaining battery level. When the scooping key 37 is input, it is switched whether or not the automatic stop at the scooping position P2 is performed. In the initial state, the scoop key 37 is turned on.

このように構成するリフターは、計量台の上から米袋を掬い取る、トラックまで運搬する、トラックの荷台高さまで持ち上げる、といった作業に使用することができる。軽量台から米袋を掬い取る作業は、昇降フォーク5を下限位置P1にして計量台の前に移動させて車輪4を固定し、昇降フォーク5をフォーク溝に差し込んでから上昇ボタン34を入力することで行われる。昇降フォーク5が下限位置P1にある状態から上昇ボタン34を入力した場合、掬い取りキーがONであると、昇降フォーク5は計量台から少し浮いた掬い取り位置P2で停止するようになる。ここで、車輪4の固定を解放して米袋を計量台から引き出し、任意の場所へ移送することが可能になる。トラックの荷台に持ち上げる作業は、上昇ボタン34を入力して昇降フォーク5を任意高さまで上昇させて行う。このとき、昇降フォーク5の上昇は、上昇ボタン34、下降ボタン35のどちらを入力しても停止させることができるので、困惑せずに操作を行うことができる。   The lifter configured in this manner can be used for operations such as scooping rice bags from the weighing platform, transporting them to a truck, and lifting them to the height of the truck bed. The operation of scooping the rice bag from the lightweight table is to move the lifting / lowering fork 5 to the lower limit position P1 and move it in front of the weighing table to fix the wheel 4 and insert the lifting / lowering fork 5 into the fork groove and then input the ascending button 34. Done in When the ascending button 34 is input while the lifting / lowering fork 5 is at the lower limit position P1, if the scooping key is ON, the lifting / lowering fork 5 stops at the scooping position P2 slightly lifted from the weighing table. Here, it becomes possible to release the fixation of the wheel 4 and pull out the rice bag from the weighing table and transfer it to an arbitrary place. The lifting operation to the truck bed is performed by inputting the ascending button 34 and raising the elevating fork 5 to an arbitrary height. At this time, the raising and lowering of the elevating fork 5 can be stopped by inputting either the ascending button 34 or the descending button 35, so that the operation can be performed without confusion.

ところで、計量台の高さは、計量器によって様々であるため、昇降フォーク5の下限位置を計量台のフォーク溝の高さに合わせる調整作業が必要となる。この調整作業について図5を用いて説明する。
調整前の昇降フォーク5の下限位置P1は、図5(a)に示すように、ハンドル付きボルト26が長穴25の最下位にあり、調整プレート24の下限スイッチ21と中段スイッチ22が両方とも昇降フォーク5のカム20によって押圧されている状態にある。この状態から、電源キー36を入力して、ハンドル付きボルト26を緩めて調整プレート24を長穴25に沿って押し上げると、図5(b)の実線に示すように、中段スイッチ22が外れてOFFになるため、モータ制御回路33では、このスイッチ22がONになるまで昇降モータ14を駆動して昇降フォーク5を上昇させ、図5(b)の点線に示すように、昇降フォーク5を調整プレート24に追従して上昇させる。また、調整プレート24を長穴25に沿って押し下げると、今度は図5(c)の実線のように、下限スイッチ21が外れてOFFになるため、モータ制御回路33では、このスイッチ21がONになるまで昇降モータ14が駆動して昇降フォーク5を下降させ、図5(c)の点線に示すように、昇降フォーク5を調整プレート24に追従して下降させる。こうして、調整プレート24の上下動に連動して、昇降フォーク5が上下するので、計量台の高さ位置に合わせて昇降フォーク5の下限位置P1を調整する作業を目視により行うことができ、従来のように、調整プレート24を固定した後、上昇キーもしくは下降キーを入力して実際の昇降フォーク5の高さを認識する調整作業に比べて容易に調整を行うことができる。尚、調整範囲は、スイッチの間隔以内とすれば、両方のスイッチが同時に外れることがない。
By the way, since the height of the weighing platform varies depending on the weighing instrument, it is necessary to adjust the lower limit position of the lifting / lowering fork 5 to the height of the fork groove of the weighing platform. This adjustment work will be described with reference to FIG.
As shown in FIG. 5A, the lower limit position P1 of the lifting fork 5 before adjustment is such that the bolt 26 with a handle is at the lowest position of the long hole 25, and both the lower limit switch 21 and the middle switch 22 of the adjustment plate 24 are It is in a state of being pressed by the cam 20 of the elevating fork 5. From this state, when the power key 36 is input, the handle-attached bolt 26 is loosened and the adjustment plate 24 is pushed up along the elongated hole 25, the middle switch 22 is released as shown by the solid line in FIG. Since the motor is turned OFF, the motor control circuit 33 drives the lift motor 14 to raise the lift fork 5 until the switch 22 is turned ON, and adjusts the lift fork 5 as shown by the dotted line in FIG. Follow the plate 24 and raise. Further, when the adjustment plate 24 is pushed down along the long hole 25, the lower limit switch 21 is removed and turned off as indicated by the solid line in FIG. 5C. Therefore, in the motor control circuit 33, the switch 21 is turned on. The elevating motor 14 is driven until the elevating fork 5 is lowered until the elevating fork 5 is lowered, and the elevating fork 5 is lowered following the adjustment plate 24 as shown by the dotted line in FIG. In this way, the elevating fork 5 moves up and down in conjunction with the vertical movement of the adjustment plate 24, so that the work of adjusting the lower limit position P1 of the elevating fork 5 according to the height position of the weighing platform can be performed visually. As described above, after the adjustment plate 24 is fixed, the adjustment can be easily performed as compared with the adjustment work of recognizing the actual height of the lifting / lowering fork 5 by inputting the up key or the down key. If the adjustment range is within the switch interval, both switches will not be removed at the same time.

尚、昇降フォーク5の各位置を検出するスイッチを接触式のものにしているが、非接触のものでもよく、特に限定されるものではない。   In addition, although the switch which detects each position of the raising / lowering fork 5 is made into a contact type, it may be a non-contact type and is not specifically limited.
