Abstract

PROBLEM TO BE SOLVED: To provide a cage truck front justification device from which a cage truck, which is sandwiched between right and left drive tires during stop of a drive motor, can be easily taken out.SOLUTION: A drive unit for transporting a cage truck having a substantially rectangular parallelepiped shape is provided on a floor surface, and the drive unit has cage truck lateral face contact drive parts on both sides of a travelling route of the cage truck. Both cage truck lateral face contact drive parts include drive tires having a drive shaft in a vertical direction and a derive motor. The drive tires of both cage truck lateral face contact drive parts are rotated in such a manner that travel faces thereof are pressed under both cage truck lateral faces by spring force and are brought into contact with each other thereby transporting the cage truck in a travel direction of the transportation route. The drive motor and the drive shaft of the drive tire respectively have connection parts which can be connected to or disconnected from each other. When the connection parts of the drive motor and the drive shaft of the drive tire are connected to each other, drive power of the drive motor is transmitted to the drive tire. When the connection parts of the drive motor and the drive shaft of the drive tire are disconnected from each other, drive power cannot be transmitted to the drive tire, and therefore, the drive tire can be freely rotated.SELECTED DRAWING: Figure 1

Description

本発明は、カゴ台車の右側面及び左側面のそれぞれの下方に駆動タイヤをばね力で押し付けて接触回転しながら搬送するタイプのカゴ台車前詰め装置において、停止時にカゴ台車を簡単に取り出すための駆動状態リリース機構を提案するものである。   The present invention relates to a cart trolley pre-packing device of a type in which a driving tire is pressed by a spring force to the lower side of each of the right side surface and the left side surface of the cage cart and conveyed while being contacted and rotated. A driving state release mechanism is proposed.

従来から、小さな荷物等を多数入れて運搬するためのカゴ台車が多く使用されている。かかるカゴ台車は、荷物の取り出しや積み込みの作業等を行うために人間が手で押して作業位置に移動されている。しかし、多数のカゴ台車を頻繁に移動させるのは、人間の労力の負担が大きく、作業効率の点で問題があった。   2. Description of the Related Art Conventionally, many carts for carrying a large number of small luggage are used. Such a cart is moved to a work position by being pushed by a human hand in order to take out or load a load. However, frequent movement of a large number of carts has a problem in terms of work efficiency due to the heavy burden of human labor.

かかる問題を考慮して、人間の労力によらずにカゴ台車を移動させるコンベヤシステムが数多く提案されている（特許文献１〜３参照）。特許文献１〜３は、いずれも駆動チェーンを持つコンベヤに台車を乗せて搬送するシステムであり、搬送ラインから台車を容易に退避させることができるものを提案する。特許文献１〜３のシステムは、複数のエリアを持たせるためにチェーンコンベヤを分割しており、チェーンコンベヤ間の隙間にスペーサを設けて台車の乗り移りをスムーズに行うようにしている。   In consideration of such a problem, many conveyor systems that move a cart without depending on human effort have been proposed (see Patent Documents 1 to 3). Patent Documents 1 to 3 are all systems that carry a carriage on a conveyor having a drive chain, and propose a system that can easily retract the carriage from a conveyance line. In the systems of Patent Documents 1 to 3, the chain conveyor is divided to have a plurality of areas, and spacers are provided in the gaps between the chain conveyors to smoothly transfer the carriage.

しかしながら、特許文献１〜３のシステムは、チェーンコンベヤを使用してカゴ台車を搬送するため、コンベヤ搬送面と床面（搬入路）を連続させるためにピットを床下に掘る必要があり、レイアウトの自由度が低く、既設の施設には容易に導入できない問題があった。また、荷物を満載した台車をコンベヤ上に載せて搬送するため、大きな駆動源が必要となり、設備コストが大きくなる問題があった。さらに、チェーンコンベヤ間の隙間に設けたスペーサは、組付け誤差により搬送面とスペーサの間に一定の段差が生じやすく、しかも台車の車輪がきちんと整列されていない場合には、車輪が段差をうまく乗り越えられず台車が詰まる問題があった。   However, since the systems of Patent Documents 1 to 3 use a chain conveyor to transport the cart, it is necessary to dig a pit below the floor in order to make the conveyor transport surface and the floor surface (loading path) continuous. There was a problem that the degree of freedom was low and it could not be easily introduced into existing facilities. In addition, since a cart full of luggage is placed on the conveyor for transport, a large drive source is required, which increases the equipment cost. In addition, the spacer provided in the gap between the chain conveyors is likely to cause a certain level difference between the transport surface and the spacer due to an assembly error, and if the wheel of the carriage is not properly aligned, the wheel will make the level difference well. There was a problem that the carriage could not be overcome and the truck was clogged.

かかる問題に対して、出願人は、従来のようにカゴ台車をチェーンコンベヤ上に載せて搬送するのではなく、カゴ台車の右側面及び左側面のそれぞれの下方に駆動タイヤをばね力で押し付けて接触回転しながらカゴ台車を搬送する方法により、比較的小さな動力でカゴ台車を容易に前送りすることができるカゴ台車前詰め装置を提案した（特許文献４参照）。   In response to such a problem, the applicant does not place the cart on the chain conveyor for transport as in the prior art, but presses the drive tire with a spring force below each of the right and left sides of the cart. There has been proposed a cart stuffing device that can easily forward the cart with relatively small power by means of conveying the cart while rotating in contact (see Patent Document 4).

特許文献４の装置は、駆動ユニットを搬送面上に設けるため、床下にピットを掘る必要がなく、簡単に床面と搬送面を連続させることができる点で優れている。   The apparatus of Patent Document 4 is excellent in that the drive unit is provided on the conveyance surface, so that it is not necessary to dig a pit under the floor, and the floor surface and the conveyance surface can be easily continued.

しかしながら、かかるカゴ台車前詰め装置を採用した場合、駆動タイヤがカゴ台車の右側面及び左側面のそれぞれの下方を押し付けて搬送するようになっているため、駆動モーターが故障や停電等で停止すると、カゴ台車が左右の駆動タイヤに挟まれたままになり、カゴ台車を装置から取り出すことは極めて困難であった。   However, when such a cart stuffing device is adopted, the drive tires are designed to push and convey the lower side of the right and left sides of the cart, so that if the drive motor stops due to a failure or a power failure, etc. The car cart remains sandwiched between the left and right drive tires, and it is extremely difficult to remove the car cart from the device.

特許第５１０７４７１号Patent No. 5107471 特許第５１０７４７２号Patent No. 5107472 特許第５１７３０４６号Japanese Patent No. 5173046 特願２０１５−２９８９６号Japanese Patent Application No. 2015-29896

本発明は、上記の出願人が提案したカゴ台車前詰め装置の問題を解消するためになされたものであり、その目的は、駆動モーター停止時に左右の駆動タイヤに挟まれたカゴ台車を装置から簡単に取り出すことができる機構を有するカゴ台車前詰め装置を提供することにある。   The present invention has been made in order to solve the problem of the car trolley pre-packing device proposed by the above-mentioned applicant. The purpose of the present invention is to remove a car trolley sandwiched between left and right drive tires when the drive motor is stopped. An object of the present invention is to provide a basket cart front-packing device having a mechanism that can be easily taken out.

本発明者は、上記目的を達成するために鋭意検討した結果、駆動モーターの駆動軸と駆動タイヤの駆動軸を分離可能とし、各駆動軸に互いに連結又は連結解除を可能にする連結部を設け、両者の駆動軸が連結されているときには駆動モーターの駆動力が駆動タイヤに伝達されるが、両者の駆動軸が連結解除されているときには駆動タイヤの駆動力が駆動タイヤに伝達されず、駆動タイヤを自由に回転可能とすることにより、駆動モーター停止時でもカゴ台車を装置から簡単に取り出せることを見出し、本発明の完成に至った。   As a result of intensive studies to achieve the above object, the present inventor has made it possible to separate the drive shaft of the drive motor and the drive shaft of the drive tire, and to provide each drive shaft with a connecting portion that can be connected to or disconnected from each other. When the two drive shafts are connected, the drive force of the drive motor is transmitted to the drive tire. However, when both drive shafts are released from the connection, the drive force of the drive tire is not transmitted to the drive tire. By making the tire freely rotatable, it was found that the cart can be easily removed from the apparatus even when the drive motor is stopped, and the present invention has been completed.

本発明のカゴ台車前詰め装置の一例について添付図面を参照しながら以下に説明するが、本発明はこれらに限定されるものではない。   Although an example of the cart stuffing device of the present invention will be described below with reference to the accompanying drawings, the present invention is not limited to these.

本発明のカゴ台車前詰め装置に使用されるカゴ台車としては、車輪付の床パネル上に荷物を順に高く積み重ね、人間の手で押して移動させることができる、略直方体形状のものを好適に使用することができる。例えば、図１に示すように、車輪付の床パネル２と、その周囲を直立して包囲する前面パネル３、後面パネル４、及び二つの対向する右側面パネル５、左側面パネル（図示せず）とからなるカゴ台車１を挙げることができ、製品によってはロールボックス、イージーコンテナー、またはパイプカーゴとも称される。本発明で使用するカゴ台車は、前面、後面、側面の幅が６０ｃｍ〜２ｍ、高さが１〜３ｍの大きさを有するタイプのものが好ましい。また、本発明で使用するカゴ台車は、その両側面の下方部分に側面の進行方向長さにわたって駆動タイヤの押圧接触可能部分（駆動力伝達可能部分）が存在することが好ましい。なお、図１は、後述する本発明のカゴ台車前詰め装置のカゴ台車右側面接触駆動部の駆動タイヤがカゴ台車の右側面の下方に接触している部分も概略的に示している。   As the cart used in the basket cart pre-packing device of the present invention, a substantially rectangular parallelepiped shape that can be piled up in order on a floor panel with wheels and moved by being pushed by a human hand is preferably used. can do. For example, as shown in FIG. 1, a floor panel 2 with wheels, a front panel 3, a rear panel 4, and two opposing right side panels 5, a left side panel (not shown) ), Which is also called a roll box, an easy container, or a pipe cargo depending on the product. The basket cart used in the present invention is preferably of a type having a front, rear and side width of 60 cm to 2 m and a height of 1 to 3 m. In addition, the cart used in the present invention preferably has a portion that can be pressed and contacted by the drive tire (a portion that can transmit the driving force) over the length of the side surface in the lower portion of both side surfaces. FIG. 1 also schematically shows a portion where the drive tire of the right side contact driving unit of the car cart of the present invention, which will be described later, is in contact with the lower side of the right side surface of the car cart.

次に、上述のカゴ台車を搬送する駆動ユニットを床面上に設けたカゴ台車前詰め装置を図３に基づいて説明する。図３は、本発明のカゴ台車前詰め装置の一例の平面概略図である。図中、１はカゴ台車であり、矢印はカゴ台車１の進行方向である。６はカゴ台車右側面接触駆動部、７はカゴ台車左側面接触駆動部であり、両方でカゴ台車を搬送する駆動ユニットを構成する。カゴ台車右側面接触駆動部６及びカゴ台車左側面接触駆動部７は、カゴ台車１の搬送経路の右側及び左側にそれぞれ設置され、カゴ台車の右側面及び左側面のそれぞれに進行方向に移動させる力を伝達する駆動タイヤ８を持つ。   Next, a description will be given, based on FIG. 3, of a car cart front-packing device in which a drive unit for conveying the car cart described above is provided on the floor surface. FIG. 3 is a schematic plan view of an example of a cart stuffing apparatus according to the present invention. In the figure, reference numeral 1 denotes a cart, and an arrow indicates a traveling direction of the cart 1. Reference numeral 6 denotes a car cart right side contact drive unit, and 7 denotes a car cart left side contact drive unit, which constitute a drive unit for transporting the car cart. The car cart right side contact driving unit 6 and the car cart left side contact driving unit 7 are respectively installed on the right side and the left side of the transport path of the car cart 1 and are moved in the traveling direction on the right side and left side of the car cart, respectively. It has a drive tire 8 that transmits force.

駆動タイヤ８は、図２及び図３に示すように鉛直方向に駆動軸を持ち、駆動源として電気モーターなどの駆動モーター９によって回転される。駆動タイヤ８は、図２に示すように同一駆動軸で複数個重ねて使用してもよい。図１及び図２では、カゴ台車右側面接触駆動部６の駆動タイヤ８の走行面が、ばね押圧手段１２のばね力によってカゴ台車１の右側面５の下方の押圧接触可能部分（駆動力伝達可能部分）に対して接触するように押し付けられる態様のみが示されているが、反対側のカゴ台車左側面接触駆動部７の駆動タイヤ８の走行面も同時に同様にカゴ台車１の左側面の下方の押圧接触可能部分（駆動力伝達可能部分）に対してばね押圧手段のばね力によって接触するように押し付けられる。このとき、カゴ台車は、右側面と左側面の両側を駆動タイヤ８によって挟まれて押し付けられている状態にあり、この状態でカゴ台車右側面接触駆動部６の駆動タイヤ８が右回転し、同時にカゴ台車左側面接触部７の駆動タイヤ８が左回転することにより、両駆動タイヤが押し付けているカゴ台車を搬送経路の進行方向に前送りさせることができる。このように、本発明の方法は、チェーンコンベヤ方式のようにカゴ台車の重量をそのまま受けて搬送するのではなく、カゴ台車の両側面をそれぞれ同時に押し付けて駆動力を伝達しているので、比較的小さい動力でカゴ台車を前送りさせることができる。   The drive tire 8 has a drive shaft in the vertical direction as shown in FIGS. 2 and 3 and is rotated by a drive motor 9 such as an electric motor as a drive source. As shown in FIG. 2, a plurality of drive tires 8 may be used by being stacked on the same drive shaft. In FIG. 1 and FIG. 2, the traveling surface of the drive tire 8 of the car cart right side contact driving unit 6 is a portion that can be pressed and contacted by the spring force of the spring pressing means 12 below the right side surface 5 of the car cart 1 (drive force transmission). Only the mode of being pressed so as to come into contact with the possible portion) is shown, but the traveling surface of the driving tire 8 of the car cart left side contact driving unit 7 on the opposite side is also the same as that of the left side surface of the car cart 1 at the same time. It is pressed so as to come into contact with the lower pressing contactable part (drive force transmitting part) by the spring force of the spring pressing means. At this time, the cage cart is in a state where both sides of the right side surface and the left side surface are sandwiched and pressed by the drive tire 8, and in this state, the drive tire 8 of the cage cart right side surface contact drive unit 6 rotates to the right, At the same time, when the drive tire 8 of the left side contact portion 7 of the car cart rotates counterclockwise, the car cart pressed by the two drive tires can be fed forward in the traveling direction of the transport path. In this way, the method of the present invention does not receive and transport the weight of the cart as it is like the chain conveyor system, but transmits the driving force by pressing both sides of the cart at the same time. The cart can be moved forward with small power.

カゴ台車右側面接触駆動部６の駆動タイヤ８とカゴ台車左側面駆動部７の駆動タイヤ８は、図３に示すように、互いにその走行面を向けてカゴ台車の進行方向と直角の直線上で対をなして存在することが好ましい。駆動タイヤの対の数は、搬送経路の距離に依存するが、少なくとも２つ、さらには少なくとも３つ、さらには少なくとも４つであることが好ましい。また、駆動タイヤの対が複数設けられる場合は、駆動タイヤの対は、搬送経路の進行方向にカゴ台車の側面の進行方向長さ以下の駆動軸の間隔距離で設けられることが好ましい。これによりカゴ台車の側面を駆動タイヤの少なくとも１対が安定して押し挟んで駆動力を伝達することができ、カゴ台車の進行方向への前送りをスムーズに行なうことができる。   As shown in FIG. 3, the drive tire 8 of the car cart right side contact driving unit 6 and the drive tire 8 of the car cart left side drive unit 7 are on a straight line perpendicular to the traveling direction of the car cart with their running surfaces facing each other. And preferably present in pairs. The number of drive tire pairs depends on the distance of the transport path, but is preferably at least 2, more preferably at least 3, and even at least 4. Further, when a plurality of pairs of drive tires are provided, it is preferable that the pairs of drive tires are provided at a distance between drive shafts that is equal to or less than the length in the traveling direction of the side surface of the cart in the traveling direction of the transport path. As a result, at least one pair of driving tires can be stably pressed between the side surfaces of the cart and the driving force can be transmitted, and the forward movement of the cart in the traveling direction can be performed smoothly.

本発明のカゴ台車前詰め装置は、図３に示すように、本発明の装置に進入して来る（具体的には１３間の直線光を遮る）カゴ台車を感知する光電センサー１３を設けることが好ましい。かかる光電センサー１３は、カゴ台車の搬送経路の最初の駆動タイヤ対のそれぞれの駆動軸を結ぶ直線（具体的には１４同士を結ぶ直線）より進行方向において好ましくは１メートル以内手前、より好ましくは１０ｃｍ〜１００ｃｍ手前の直線（具体的には１３同士を結ぶ直線）上にカゴ台車の先端が到達することを感知するように構成される。このように進入して来るカゴ台車を予め感知することにより、その後に続く駆動タイヤの回転の始動・停止を適切に制御することができる。   As shown in FIG. 3, the basket cart front-packing device according to the present invention is provided with a photoelectric sensor 13 that detects the cage cart entering the device according to the present invention (specifically, blocking the linear light between 13). Is preferred. The photoelectric sensor 13 is preferably within 1 meter before the straight line connecting the respective drive shafts of the first drive tire pair of the first pair of drive tires (specifically, the straight line connecting 14 to each other) in the traveling direction of the cart, more preferably It is configured so as to detect that the tip of the cart is on a straight line 10 cm to 100 cm in front (specifically, a straight line connecting 13 to each other). Thus, by detecting in advance the cart that has entered the vehicle, it is possible to appropriately control the start / stop of the rotation of the drive tire that follows.

本発明のカゴ台車前詰め装置は、複数のカゴ台車が搬送され、図５に示すように各カゴ台車が順次所定の前後間隔で所定の予定位置に停止される場合に、各停止予定位置の先端より進行方向において５０ｃｍ以内手前、より好ましくは１０ｃｍ〜５０ｃｍ手前にカゴ台車の先端が到達することを感知する光電センサー１４を設けることが好ましい。かかる光電センサー１４は、搬送するカゴ台車の先端と平行に配置され、具体的には図３に示すように１４間の直線光を遮るカゴ台車を感知するように構成される。上述の光電センサー１４がカゴ台車を感知することでカゴ台車の位置情報を取得する。光電センサー１４の位置は可変であり、カゴ台車の停止間隔により決定される。また、光電センサー１４は、駆動タイヤの始動・停止スイッチとしての働きを持つ。光電センサー１４により駆動タイヤの回転の始動停止を適切に制御することで、カゴ台車間の衝突を回避しながら複数のカゴ台車をスムーズに移動することができる。   The basket cart front-packing device of the present invention has a plurality of carts transported, and when each cart is sequentially stopped at a predetermined planned position at a predetermined longitudinal interval as shown in FIG. It is preferable to provide a photoelectric sensor 14 that senses that the tip of the cart is reached within 50 cm, more preferably 10 cm to 50 cm, in the traveling direction from the tip. The photoelectric sensor 14 is arranged in parallel with the front end of the transporting cart, and specifically, is configured to sense the cart that blocks the linear light between 14 as shown in FIG. The photoelectric sensor 14 described above senses the cart and acquires the position information of the cart.

FIG. 10 is a schematic diagram of a part of the cart trolley pre-packing device according to the present invention as viewed from the rear when the drive tire and the drive shaft of the drive motor are connected to each other, and viewed from the corresponding side. A schematic diagram of the area near the drive motor is shown on the left. FIG. 11 is a schematic view of a portion near the drive motor in FIG. 10 as viewed from above. 12 is a view similar to FIG. 10 showing a state where the drive tire and the drive shaft of the drive motor are disconnected from each other, and FIG. 13 is a view where the drive tire and the drive shaft of the drive motor are connected to each other. It is the same figure as FIG. 10 which showed the state in the middle of changing to a connection cancellation | release state (FIG. 12) from a state (FIG. 10). In each figure, 1 is a car cart, 7 is a car cart left side contact drive unit, 8 is a drive tire, 9 is a drive motor, 10 is a drive shaft connecting portion of the drive motor, and 11 is a drive shaft connecting portion of the drive tire. , 12 is a spring pressing means, 15 is a lever, 16 is a lift guide, 17 is a lift plate, 18 is a lever rotation fulcrum, 19 is a lever end support shaft, and 20 is a lever end support bearing plate.

本発明の装置では、図１０〜図１３に示すように、駆動タイヤ８と駆動モーター９は、同じ鉛直方向に駆動軸を持っており、駆動モーター９の駆動軸の連結部１０と駆動タイヤ８の駆動軸の連結部１１は、それぞれ互いに図１０のように連結する状態にしたり、図１２のように連結解除の状態にすることができる。図１３は、両連結部１０，１１が図１０の連結状態から図１２の連結解除状態に移行する途中の状態を示す。図１０のように両連結部１０，１１が互いに連結されているとき、駆動モーター９の駆動力は駆動タイヤ８に有効に伝達されるが、図１２のように両連結部１０，１１の連結が解除されているとき、駆動モーター９の駆動力は駆動タイヤ８に全く伝達されない。駆動力が伝達されないときは、駆動タイヤ８は自由に回転することができる。従って、故障や停電等により駆動モーター９が停止されたときでも、カゴ台車１は、両連結部１０，１１を図１２のように連結解除状態にして駆動タイヤ８を自由に動かすことにより、装置から容易に取り出すことができる。   In the apparatus of the present invention, as shown in FIGS. 10 to 13, the drive tire 8 and the drive motor 9 have a drive shaft in the same vertical direction, and the drive shaft connecting portion 10 of the drive motor 9 and the drive tire 8. The drive shaft connecting portions 11 can be connected to each other as shown in FIG. 10, or can be released from the connection as shown in FIG. FIG. 13 shows a state in which both the connecting portions 10 and 11 are in the process of shifting from the connected state of FIG. 10 to the disconnected state of FIG. When the two connecting portions 10 and 11 are connected to each other as shown in FIG. 10, the driving force of the drive motor 9 is effectively transmitted to the driving tire 8, but the connection between the connecting portions 10 and 11 is shown in FIG. When is released, the driving force of the driving motor 9 is not transmitted to the driving tire 8 at all. When the driving force is not transmitted, the driving tire 8 can freely rotate. Therefore, even when the drive motor 9 is stopped due to a failure, a power failure, etc., the car cart 1 can move the drive tire 8 freely by setting both the connecting portions 10 and 11 to the disconnected state as shown in FIG. Can be taken out easily.

両連結部１０，１１の連結又は連結解除は、様々な公知の手段を採用して達成することができるが、例えば駆動モーター９を上下方向に昇降させることによって行なうことが好ましい。具体的には、駆動モーター９を上昇させると、両連結部１０，１１は連結解除され、駆動モーター９を下降させると、両連結部１０，１１は連結され、駆動モーター９の駆動力が駆動タイヤ８に伝達される。これにより、両連結部１０，１１の連結操作を比較的簡単に行なうことができる。   The connection or disconnection of the connecting portions 10 and 11 can be achieved by employing various known means, but is preferably performed by elevating and lowering the drive motor 9 in the vertical direction, for example. Specifically, when the drive motor 9 is raised, both the connecting portions 10 and 11 are released, and when the drive motor 9 is lowered, both the connecting portions 10 and 11 are connected and the driving force of the drive motor 9 is driven. It is transmitted to the tire 8. Thereby, connection operation of both the connection parts 10 and 11 can be performed comparatively easily.

また、両連結部１０，１１は、それぞれ金属製又は合成樹脂製の凹凸状の歯を有し、それらが互いにかみ合って連結されることによって駆動モーター９の駆動力が駆動タイヤ８に伝達されることが好ましい。これにより両連結部１０，１１の上下方向の連結力だけでなく、回転方向の連結力も強固にすることができる。   Moreover, both the connection parts 10 and 11 have the uneven | corrugated tooth | gear made from metal or a synthetic resin, respectively, and the driving force of the drive motor 9 is transmitted to the drive tire 8 by meshing and connecting them. It is preferable. Thereby, not only the connection force of the both connection parts 10 and 11 in the up-down direction but also the connection force in the rotation direction can be strengthened.

駆動モーター９は、図１０〜図１３に示すように、駆動モーター９の側面に取り付けた昇降プレート１７を昇降ガイド１６で鉛直方向に上下することによって一緒に上下方向に移動できることが好ましい。これにより、駆動モーター９は、正確に鉛直方向に上下に移動することができる。昇降プレート１７には、昇降プレート１７を昇降する操作を行なうことができる長尺形の板状のレバー１５を設けることが好ましい。レバー１５は、図１０〜図１３に示すように、その端部にレバー端支持軸１９を設け、その端部より離れた位置にレバー回転支点１８を設け、レバー回転支点１８を中心にレバー１５が回転できるようにすることが好ましい。この場合、レバー１５の回転により、レバー端支持軸１９が図１０、図１３、図１２の位置に順に又は逆の順に移動するが、実際に昇降プレート１７とそれを取り付けた駆動モーター９を昇降させるためには、水平方向にレバー端支持軸１９を受けるレバー端支持軸受板２０を設けてレバー１５の回転時のレバー端支持軸１９の高さを調整することが好ましい。具体的には、図１０の両連結部１０，１１の連結状態で矢印方向にレバー１５を動かすと、図１３のようにレバー１５がレバー回転支点１８を中心として左回転し、レバー端支持軸１９はレバー端支持軸受板２０の水平方向の受部上で支持されながら右方向に移動し、最終的に図１２のようにレバー回転支点１８とレバー端支持軸１９が鉛直方向に並んだ時点でレバー端支持軸受板２０の鉛直方向の受部にレバー端支持軸１９が当接して停止し、両連結部１０，１１の連結解除を行なうようにすることが好ましい。また、同様にレバー１５の逆回転の操作により両連結部１０，１１の図１２の連結解除状態から図１３の状態を経て図１０の連結状態に戻すことができることが好ましい。これらの方法では、レバー回転支点１８とレバー端支持軸１９の間の距離から図１０の状態のレバー端支持軸１９とレバー端支持軸受板２０の水平方向の受部の間の距離を引いた分だけ昇降プレート１７とそれを取り付けた駆動モーター９を昇降させることができる。昇降距離の調整は、例えばこれらの距離の変更で行なうことができる。   As shown in FIGS. 10 to 13, it is preferable that the drive motor 9 can move up and down together by moving up and down a lifting plate 17 attached to the side surface of the driving motor 9 in the vertical direction by the lifting guide 16. As a result, the drive motor 9 can accurately move up and down in the vertical direction. The elevating plate 17 is preferably provided with a long plate-like lever 15 that can perform an operation for elevating the elevating plate 17. As shown in FIGS. 10 to 13, the lever 15 is provided with a lever end support shaft 19 at its end, a lever rotation fulcrum 18 at a position away from the end, and the lever 15 around the lever rotation fulcrum 18. Is preferably rotatable. In this case, the lever end support shaft 19 is moved to the positions shown in FIGS. 10, 13, and 12 in order or in reverse order by the rotation of the lever 15, but the elevator plate 17 and the drive motor 9 to which the elevator plate 17 is actually attached are moved up and down. For this purpose, it is preferable to adjust the height of the lever end support shaft 19 when the lever 15 rotates by providing a lever end support bearing plate 20 that receives the lever end support shaft 19 in the horizontal direction. Specifically, when the lever 15 is moved in the direction of the arrow in the connected state of both the connecting portions 10 and 11 in FIG. 10, the lever 15 rotates counterclockwise around the lever rotation fulcrum 18 as shown in FIG. 19 moves to the right while being supported on the horizontal receiving portion of the lever end support bearing plate 20, and finally when the lever rotation fulcrum 18 and the lever end support shaft 19 are aligned vertically as shown in FIG. Therefore, it is preferable that the lever end support shaft 19 abuts on the receiving portion of the lever end support bearing plate 20 in the vertical direction and stops, and the connection portions 10 and 11 are disconnected. Similarly, it is preferable that both the connecting portions 10 and 11 can be returned to the connected state shown in FIG. 10 from the released state shown in FIG. In these methods, the distance between the lever end support shaft 19 and the lever end support bearing plate 20 in the horizontal direction in the state shown in FIG. 10 is subtracted from the distance between the lever rotation fulcrum 18 and the lever end support shaft 19. The raising / lowering plate 17 and the drive motor 9 to which the raising / lowering plate 17 is attached can be raised / lowered by the same amount. The elevation distance can be adjusted, for example, by changing these distances.

本発明の装置の一例を図面に基づいて上で説明したが、カゴ台車の両側面のそれぞれの下方に駆動タイヤを接触押圧しながら駆動力を伝達してカゴ台車を前送りすることができる限り、本発明の装置の一部の構成要素の従来技術による置換、追加、及び／又は削除は本発明の技術的範囲の範疇に属する。例えば、駆動タイヤをばね力で押し付けて駆動力を伝達する手段や光電センサーは、従来公知の同様の機能を有するものに変更することができる。また、駆動モーターと駆動タイヤの連結又は連結解除を行なうことができる機構についても、上述の例に限らず、本発明の目的と機能を損なわない限り、適宜設計変更することができる。   Although an example of the device of the present invention has been described above with reference to the drawings, as long as the driving force can be transmitted to the lower side of each side surface of the cart and the driving force can be transmitted while the driving tire is contacted and pressed, the cart can be forwarded. Any replacement, addition and / or deletion of some components of the apparatus of the present invention by the prior art falls within the scope of the present invention. For example, the means for transmitting the driving force by pressing the driving tire with a spring force and the photoelectric sensor can be changed to those having a conventionally known similar function. Further, the mechanism capable of connecting or releasing the drive motor and the drive tire is not limited to the above-described example, and can be appropriately modified as long as the object and function of the present invention are not impaired.

本発明のカゴ台車前詰め装置は、チェーンコンベヤ式のように床下にピットを掘らずに床面と搬送面の連続を容易に達成でき、しかも低コストの簡単な構造を持つ利点を有する。また、駆動モーター停止時にもカゴ台車を簡単に取り出すことができる利点を有する。従って、荷物の配送、仕分けを行なう業界において極めて有用である。   The basket cart pre-packing device of the present invention has an advantage that it can easily achieve continuation of the floor surface and the conveying surface without digging a pit under the floor as in the chain conveyor type, and has a simple structure with low cost. Further, there is an advantage that the cart can be easily taken out even when the drive motor is stopped. Therefore, it is extremely useful in the industry for delivering and sorting packages.
