Description

本発明は、トラック等の荷台に設備されて積載された貨物の荷台上での移動に使用される車両用荷役装置に係る技術分野に属する。   The present invention belongs to a technical field related to a vehicle loading / unloading device used for movement of cargo loaded on a loading platform such as a truck.

最近、トラック等の貨物運送用の車両では、貨物が積載される荷台の床面にコンベアが設置された車両用荷役装置が設備されるようになってきている。この車両用荷役装置は、コンベアを駆動することによって、荷台の後方側で荷揚げされて積載された貨物を荷台の前方側まで移動できるようにし、荷降ろしの際に荷台の前方側に積載されている貨物を荷台の後方側まで移動できるようにして、荷台上での作業員の荷役作業を軽減するものである。特に、この車両用荷役装置は、荷台上の空間が側パネル,天パネルで囲まれて制約されるバンタイプの貨物運送用の車両で有用性を発揮する。   In recent years, vehicles for cargo transportation such as trucks have been equipped with a vehicle loading / unloading device in which a conveyor is installed on the floor of a loading platform on which cargo is loaded. This vehicle loading / unloading device enables the cargo loaded and loaded on the rear side of the loading platform to be moved to the front side of the loading platform by driving the conveyor, and loaded on the front side of the loading platform when unloading. It is possible to reduce the load handling work of workers on the loading platform by allowing the cargo to be moved to the rear side of the loading platform. In particular, this vehicular cargo handling device is useful in a van-type cargo transportation vehicle in which the space on the loading platform is surrounded and restricted by side panels and top panels.

この車両用荷役装置では、コンベアを荷台の前後方向である2方向へ駆動させなければならないため、コンベアの駆動機構が大型化するという不具合がある。そこで、搭載重量,搭載スペースの制約のある車両への設備を容易にするために、コンベアの駆動機構の大型化を避けることのできる車両用荷役装置の開発が要望されている。   In this vehicular cargo handling apparatus, since the conveyor must be driven in two directions that are the front and rear directions of the loading platform, there is a problem that the driving mechanism of the conveyor is enlarged. Therefore, in order to facilitate the installation of vehicles with restrictions on the mounting weight and the mounting space, there is a demand for the development of a vehicle handling device that can avoid an increase in the size of the conveyor drive mechanism.

従来、コンベアの駆動機構の大型化を避けることを指向した車両用荷役装置としては、例えば、下記特許文献1に記載のものが知られている。
この特許文献1には、貨物が積載される荷台の床面に設置され貨物を荷台の前後方向へ移動させるコンベアが荷台の前後方向にエンドレス状に掛渡されて配設された車両用荷役装置が記載されている。
2. Description of the Related Art Conventionally, as a vehicular cargo handling apparatus aimed at avoiding an increase in the size of a conveyor drive mechanism, for example, the one described in Patent Document 1 below is known.
This Patent Document 1 discloses a vehicle handling apparatus in which a conveyor that is installed on a floor surface of a cargo bed on which cargo is loaded is moved in an endless manner in the front-back direction of the cargo bed and is disposed in an endless manner. Is described.

特許文献1に係る車両用荷役装置は、コンベアの駆動機構の電気的な切換え等(例えば、駆動モータの正逆の回転方向の切換え)によってコンベアの駆動方向を切換えて、貨物を荷台の前後方向のいずれの方向へも移動させることができるようにすることで、コンベアの駆動機構の大型化を避けるものである。即ち、コンベアの駆動機構として、前方移動用,後方移動用を共有化することで大型化を避けるものである。

特開2000−16142号公報
The vehicle handling apparatus according to Patent Document 1 switches the conveyor drive direction by electrical switching of the conveyor drive mechanism or the like (for example, switching between the forward and reverse rotation directions of the drive motor), and loads the cargo in the longitudinal direction of the loading platform. By making it possible to move in any of these directions, an increase in the size of the drive mechanism of the conveyor is avoided. That is, as the drive mechanism of the conveyor, the forward movement and the backward movement are shared to avoid an increase in size.

JP 2000-16142 A

特許文献1に係る車両用荷役装置では、コンベアがエンドレス状に掛渡され、荷台の床面の上のほぼ全面にコンベアの二段の配設構造が収容されるスペースを確保しなければならないため、貨物が積載されるコンベアの積載面が高くなって貨物の積載量が少なくなってしまうという問題点がある。   In the vehicle handling apparatus according to Patent Document 1, the conveyor is passed in an endless manner, and a space for accommodating the two-stage arrangement structure of the conveyor must be secured on almost the entire surface of the floor of the loading platform. However, there is a problem that the loading surface of the conveyor on which the cargo is loaded becomes high and the cargo loading amount decreases.

本発明は、このような問題点を考慮してなされたもので、貨物が積載されるコンベアの積載面を低くして貨物の積載量を多くすることのできる車両用荷役装置を提供することを課題とする。   The present invention has been made in view of such problems, and provides a vehicle handling apparatus capable of increasing the cargo loading amount by lowering the loading surface of the conveyor on which the cargo is loaded. Let it be an issue.

前述の課題を解決するため、本発明に係る車両用荷役装置は、特許請求の範囲の各請求項に記載の手段を採用する。   In order to solve the above-described problem, the vehicle handling apparatus according to the present invention employs means described in each of the claims.

即ち、請求項1では、貨物が積載される荷台の床面に貨物を荷台の前後方向へ移動させるコンベアが設置された車両用荷役装置において、コンベアはシート状に形成されて荷台の後方側に設置されたローラに巻取り,繰出し可能に連結されるとともに繰出し先端が荷台の前後方向へ移動可能に配設された移動用チェーンに連結され、ローラ,移動用チェーンを駆動する駆動部は共通化されてコンベアの巻取りの際にローラを駆動しコンベアの繰出しの際に移動用チェーンを駆動する自動的な切換えがなされる駆動伝達機構が付設されていることを特徴とする。   That is, according to claim 1, in the vehicle loading / unloading device in which the conveyor for moving the cargo in the front-rear direction of the loading platform is installed on the floor surface of the loading platform on which the cargo is loaded, the conveyor is formed in a sheet shape on the rear side of the loading platform. It is connected to the installed roller so that it can be wound and fed out, and the leading end is connected to a moving chain that can be moved in the front-rear direction of the loading platform, and the drive unit that drives the roller and moving chain is shared. A drive transmission mechanism for automatically switching between driving rollers when winding the conveyor and driving the moving chain when feeding the conveyor is provided.

この手段では、シート状のコンベアをローラに巻取り移動用チェーンで繰出すことでコンベアの二段の配設構造を避け、ローラ,移動用チェーンの駆動部を自動的な切換えがなされる駆動伝達機構を介して共通化することで駆動部,駆動伝達機構を荷台の床面の凹部等を利用して設置することができるようにする。   In this means, a sheet-like conveyor is wound around a roller by a take-up movement chain, thereby avoiding a two-stage arrangement structure of the conveyor, and a drive transmission in which the roller and the movement chain drive unit are automatically switched. By sharing the mechanism through the mechanism, the drive unit and the drive transmission mechanism can be installed using the recesses on the floor surface of the cargo bed.

また、請求項2では、請求項1の車両用荷役装置において、駆動伝達機構は駆動力を受けて回転する駆動円盤と駆動円盤の両端面に接合され駆動円盤と同軸線上で回転される従動円盤と駆動円盤,従動円盤の間に設けられ駆動円盤の一方向の回転に従動円盤を追従して回転させ他方向の回転に従動円盤を追従して回転させないワンウエイクラッチとを備え、一方の従動円盤はローラに連結され、他方の従動円盤は移動用チェーンに連結され、ワンウエイクラッチは両従動盤側で回転が追従される方向が逆向きであることを特徴とする。   According to a second aspect of the present invention, in the vehicle loading / unloading apparatus according to the first aspect, the drive transmission mechanism receives a driving force to rotate and the driven disk is joined to both end faces of the driving disk and rotated on the same axis as the driving disk. And a one-way clutch that is provided between the drive disk and the driven disk and that rotates following the driven disk in one direction and does not rotate the driven disk in the other direction. Is connected to a roller, the other driven disk is connected to a moving chain, and the one-way clutch is characterized in that the direction in which rotation is followed on both driven disks is opposite.

この手段では、駆動伝達機構がワンウエイクラッチを駆動円盤,従動円盤の間に設けた円盤形に形成されることでコンパクト性が備えられる。   In this means, the drive transmission mechanism is formed in a disk shape in which the one-way clutch is provided between the drive disk and the driven disk, thereby providing compactness.

また、請求項3では、請求項2の車両用荷役装置において、駆動伝達機構のワンウエイクラッチは従動円盤の駆動円盤への当接面に軸方向に傾斜した深さを有して周方向に円弧形に延びた係合溝と駆動円盤に収容され両従動円盤に設けられた係合溝に対して選択的に出没して係合,離脱する係合体とからなることを特徴とする。   According to a third aspect of the present invention, in the vehicle loading apparatus according to the second aspect, the one-way clutch of the drive transmission mechanism is circular in the circumferential direction with a depth inclined in the axial direction on the contact surface of the driven disk with the drive disk. It is characterized by comprising an engagement groove extending in an arc shape and an engagement body that is selectively housed in and out of the engagement groove accommodated in the driven disk and engaged and disengaged.

この手段では、駆動伝達機構のワンウエイクラッチが従動円盤の駆動円盤への当接面に設けられた係合溝と駆動円盤に収容された係合体とで構成される。   In this means, the one-way clutch of the drive transmission mechanism is composed of an engagement groove provided on the contact surface of the driven disk with the drive disk and an engagement body accommodated in the drive disk.

また、請求項4では、請求項1〜3いずれかの車両用荷役装置において、コンベアは繰出し先端の上に積載された貨物の側面に当接される貨物支持体が立設されて貨物支持体を介して移動用チェーンに連結されていることを特徴とする。   According to a fourth aspect of the present invention, in the vehicular cargo handling apparatus according to any one of the first to third aspects, the conveyor is provided with a freight support that is in contact with a side surface of the freight loaded on the leading end, and the freight support. It is connected with the chain for movement through.

この手段では、貨物支持体を介してコンベア,移動用チェーンが連結される。   In this means, the conveyor and the moving chain are connected via the cargo support.

本発明に係る車両用荷役装置は、シート状のコンベアをローラに巻取り移動用チェーンで繰出すことでコンベアの二段の配設構造を避け、ローラ,移動用チェーンの駆動部を自動的な切換えがなされる駆動伝達機構を介して共通化することで駆動部,駆動伝達機構を荷台の床面の凹部等を利用して設置することができるようにしたため、貨物が積載されるコンベアの積載面を低くして貨物の積載量を多くすることができる効果がある。   The vehicle cargo handling device according to the present invention avoids a two-stage arrangement structure of a conveyor by feeding a sheet-like conveyor around a roller by a winding movement chain, and automatically drives a roller and a moving chain drive unit. Since the drive unit and the drive transmission mechanism can be installed using the recesses on the floor of the loading platform, etc., by using a common drive transmission mechanism, the loading of the conveyor on which the cargo is loaded There is an effect that the surface can be lowered and the cargo load can be increased.

さらに、請求項2として、駆動伝達機構がワンウエイクラッチを駆動円盤,従動円盤の間に設けた円盤形に形成されることでコンパクト性が備えられるため、荷台の床面への設置スペースの確保が容易になる効果がある。   Further, as claimed in claim 2, since the drive transmission mechanism is formed in a disk shape in which the one-way clutch is provided between the driving disk and the driven disk, the compactness is provided, so that the installation space on the floor of the loading platform can be secured. There is an effect that becomes easy.

さらに、請求項3として、駆動伝達機構のワンウエイクラッチが従動円盤の駆動円盤への当接面に設けられた係合溝と駆動円盤に収容された係合体とで構成されるため、構造の複雑化が避けられ安価,容易な製造が可能になる効果がある。   Further, since the one-way clutch of the drive transmission mechanism is composed of an engagement groove provided on the contact surface of the driven disk with the drive disk and an engagement body accommodated in the drive disk, the structure of the drive transmission mechanism is complicated. This is advantageous in that it is easy to manufacture at low cost.

さらに、請求項4として、貨物支持体を介してコンベア,移動用チェーンが連結されるため、コンベアに掛かる移動用チェーンの繰出し力を貨物支持体で分散均等化することができ、コンベアの繰出しを円滑にすることができる効果がある。   Further, as claimed in claim 4, since the conveyor and the moving chain are connected via the cargo support, the feeding force of the moving chain applied to the conveyor can be distributed and equalized by the cargo support. There is an effect that can be made smooth.

以下、本発明に係る車両用荷役装置を実施するための最良の形態を図面に基づいて説明する。   The best mode for carrying out a vehicular cargo handling apparatus according to the present invention will be described below with reference to the drawings.

The cargo support body 3 is formed in a torii-shaped frame and is fed forward of the conveyor 1 (winding end). It stands up to the height of the top of the loading platform B up to the top panel Bb. The cargo support 3 and the leading end of the conveyor 1 are fixed via plate-shaped reinforcing metal fittings extending in the width direction of the loading platform B so that the conveyor 1 does not lean, twist or the like. For example, the side surface of the cargo support 3 travels inside a U-shaped traveling rail disposed along the side panel Bc of the loading platform B so that the smoothness of the movement of the cargo support 3 is ensured. A travel roller mounting plate on which the travel roller is rotatably supported is fixed.

移動用チェーン4は、図1,図2に示すように、荷台Bの床面Baの前方側と後方側とに配置されたスプロケット10,20にエンドレス状に掛渡されて荷台Bの前後方向に配設されて荷台2の幅方向に2本が並列されている。スプロケット10,20は、荷台Bの床面Baの前方側と後方側とに軸線が荷台Bの幅方向へ設定されて配設された回転軸30,40に2本の移動用チェーン4に対応して間隔を介した1対がそれぞれ支持されている。スプロケット10,20の近くの荷台Bの後方側には、移動用チェーン4のエンドレス状の往復ラインの間隔を狭める補助スプロケット50が設置されている。また、荷台Bの後方側の回転軸30には、駆動伝達用スプロケット60が固定されている。移動用チェーン4の一箇所と貨物支持体3(コンベア1の繰出し先端)とは、固定用ブラケット70で固定されている。   As shown in FIGS. 1 and 2, the moving chain 4 is stretched endlessly on sprockets 10 and 20 disposed on the front side and the rear side of the floor surface Ba of the loading platform B to move in the longitudinal direction of the loading platform B. The two are arranged in parallel in the width direction of the loading platform 2. The sprockets 10 and 20 correspond to the two moving chains 4 on the rotary shafts 30 and 40 arranged with the axis lines set in the width direction of the loading platform B on the front side and the rear side of the floor surface Ba of the loading platform B. Thus, a pair with an interval is supported. An auxiliary sprocket 50 that narrows the interval between the endless reciprocating lines of the moving chain 4 is installed on the rear side of the loading platform B near the sprockets 10 and 20. A drive transmission sprocket 60 is fixed to the rotary shaft 30 on the rear side of the loading platform B. One portion of the moving chain 4 and the cargo support 3 (the leading end of the conveyor 1) are fixed by a fixing bracket 70.

駆動伝達機構6のワンウエイクラッチ64は、係合溝641,係合体642からなる。係合溝641は、従動円盤62,63の駆動円盤61への当接面である一方の端面に軸方向に傾斜した深さを有して周方向に円弧形に延びて6個が放射状の配置で刻設されている。この係合溝641は、傾斜面641aの最も深い部分に深さを一定にした平坦部分641bが設けられ、傾斜面641aの最も浅い部分が、従動円盤62,63の端面に到達している。なお、図5,図12から明らかなように、従動円盤62,63の係合溝641の傾斜面641aの傾斜方向が両従動円盤62,63で互いに逆方向に設定されている。係合体642は、外径が駆動円盤61のワンウエイクラッチ収容孔613の径とほぼ一致し軸長が駆動円盤61の軸長と係合溝641の平坦部分641bの深さとの和とほぼ一致するピン形に形成されている。係合体642の端面は、半球形の丸頭642aに形成されている。係合体642の周面には、断面が半円形に凹んだ環状溝642bが間隔を介して2条刻設されている。この係合体642は、駆動円盤61のワンウエイクラッチ収容孔613に収容されて係合溝641に対して出没されるもので、出没の限界位置で環状溝642bが駆動円盤61のロック機構収容孔614に対面するようになっている。   The one-way clutch 64 of the drive transmission mechanism 6 includes an engagement groove 641 and an engagement body 642. The engagement grooves 641 have a depth inclined in the axial direction at one end surface which is a contact surface of the driven disks 62 and 63 with the drive disk 61, and extend in an arc shape in the circumferential direction, and six of them are radial. It is carved with the arrangement of. The engaging groove 641 is provided with a flat portion 641b having a constant depth at the deepest portion of the inclined surface 641a, and the shallowest portion of the inclined surface 641a reaches the end surfaces of the driven disks 62 and 63. As is clear from FIGS. 5 and 12, the inclined directions of the inclined surfaces 641 a of the engaging grooves 641 of the driven disks 62 and 63 are set in opposite directions in the driven disks 62 and 63. The engaging body 642 has an outer diameter that substantially matches the diameter of the one-way clutch housing hole 613 of the driving disk 61 and an axial length that substantially matches the sum of the axial length of the driving disk 61 and the depth of the flat portion 641 b of the engaging groove 641. It is formed in a pin shape. The end surface of the engaging body 642 is formed as a hemispherical round head 642a. On the peripheral surface of the engaging body 642, two annular grooves 642b having a semicircular cross section are provided with a gap therebetween. The engaging body 642 is housed in the one-way clutch housing hole 613 of the driving disk 61 and protrudes and retracts with respect to the engaging groove 641, and the annular groove 642 b is formed in the locking mechanism housing hole 614 of the driving disk 61 at the limit position of the projecting and retracting. Face to face.

駆動伝達機構6のロック機構65は、ボール651,コイルスプリング652,止ネジ653からなる。ボール651は、駆動円盤61のロック機構収容孔614から出没してワンウエイクラッチ64の係合体642の環状溝642bに係合する球体からなる。コイルスプリング652は、駆動円盤61のロック機構収容孔614に収容されてボール651をワンウエイクラッチ64の係合体642方向に弾圧する。止ネジ653は、駆動円盤61のロック機構収容孔614の駆動円盤61の周面近くに螺合されてコイルスプリング652の弾圧の反力を受ける。   The lock mechanism 65 of the drive transmission mechanism 6 includes a ball 651, a coil spring 652, and a set screw 653. The ball 651 is formed of a spherical body that protrudes from and enters the lock mechanism accommodation hole 614 of the drive disk 61 and engages with the annular groove 642 b of the engagement body 642 of the one-way clutch 64. The coil spring 652 is housed in the lock mechanism housing hole 614 of the drive disk 61 and presses the ball 651 toward the engaging body 642 of the one-way clutch 64. The set screw 653 is screwed into the lock mechanism accommodation hole 614 of the drive disk 61 near the peripheral surface of the drive disk 61 and receives the reaction force of the spring force of the coil spring 652.

この形態によると、コンベア1が二段の配設構造とならないため、ローラ2,駆動機構5,駆動伝達機構6を荷台Bの床面Baの凹部等を利用して設置することにより、貨物が積載されるコンベア1の積載面となる配設面を低くすることができる。従って、荷台Bの容積を貨物の積載のために有効利用して積載量を多く確保することができる。また、コンベア1の二段の配設構造を避けて取付スペースの小規模化が図られているため、既に使用されているトラックTの固定的な荷台Bに簡単に改修装備することができる。なお、駆動部5が1基からなることも、取付スペースの小規模化に寄与する。また、駆動部5に付設される駆動伝達機構6がワンウエイクラッチ64を駆動円盤61,従動円盤62,63の間に設けた円盤形に形成されることでコンパクト性が備えられることも、荷台Bの床面Baの凹部等を利用しての設置に役立つ。この駆動伝達機構6については、ワンウエイクラッチ64が従動円盤62,63の駆動円盤61への当接面である一方の端面に設けられた係合溝641と駆動円盤61に収容された係合体642とで構成されるため、構造の複雑化が避けられ安価,容易な製造が可能である。また、移動用チェーン4が補助スプロケット50でエンドレス状の往復ラインの間隔を狭められていることも、貨物が積載されるコンベア1の積載面となる配設面を低くすることに寄与する。   According to this embodiment, the conveyor 1 does not have a two-stage arrangement structure. Therefore, by installing the roller 2, the drive mechanism 5, and the drive transmission mechanism 6 using the concave portion of the floor surface Ba of the loading platform B, the cargo is The arrangement | positioning surface used as the loading surface of the conveyor 1 loaded can be made low. Therefore, it is possible to effectively use the volume of the loading platform B for loading cargo and to secure a large loading capacity. Further, since the installation space is reduced by avoiding the two-stage arrangement structure of the conveyor 1, the fixed loading platform B of the truck T that has already been used can be easily retrofitted. Note that the fact that the drive unit 5 is composed of one unit also contributes to a reduction in the mounting space. In addition, the drive transmission mechanism 6 attached to the drive unit 5 is formed in a disk shape in which the one-way clutch 64 is provided between the drive disk 61 and the driven disks 62 and 63, so that compactness is provided. It is useful for the installation using the concave portion of the floor surface Ba of the floor. In the drive transmission mechanism 6, the one-way clutch 64 is provided with an engagement groove 641 provided on one end surface which is a contact surface of the driven disks 62 and 63 with the drive disk 61, and an engagement body 642 accommodated in the drive disk 61. Therefore, it is possible to manufacture at low cost and easily without complicating the structure. Further, the distance between the endless reciprocating lines of the moving chain 4 being reduced by the auxiliary sprocket 50 also contributes to lowering the arrangement surface that is the loading surface of the conveyor 1 on which cargo is loaded.

この形態を使用するには、コンベア1を駆動部5の駆動でローラ2から繰出すことによって、荷台Bの後方側で荷揚げされて積載された貨物を荷台Bの前方側まで移動させ、コンベア1を駆動部5の逆方向への駆動でローラ2に巻取ることによって、荷降ろしの際に荷台Bの前方側に積載されている貨物を荷台Bの後方側まで移動させることになる。   In order to use this form, the conveyor 1 is driven from the roller 2 by driving the drive unit 5 to move the cargo loaded and loaded on the rear side of the loading platform B to the front side of the loading platform B. Is wound around the roller 2 by driving the drive unit 5 in the reverse direction, so that the cargo loaded on the front side of the loading platform B is moved to the rear side of the loading platform B at the time of unloading.

駆動部5の駆動モータ51が正方向に回転されると、駆動軸52も正方向に回転駆動されることになる。そして、駆動伝達機構6は、固定リング80を介して駆動円盤61が駆動部5の駆動軸52と一体的に正方向に回転されることになる。このとき、図3,図6,図7,図12に示すように、駆動伝達機構6のワンウエイクラッチ64の係合体642が係合溝641の傾斜面641bを滑り一方の従動円盤62に設けられている係合溝641の平坦部分641bに至って係合溝641に係止される。即ち、駆動伝達機構6のワンウエイクラッチ64が駆動円盤61と一方の従動円盤62との間で係合接続された状態となって、一方の従動円盤62が駆動円盤61に追従して正方向に回転されることになる。なお、このとき、駆動伝達機構6のワンウエイクラッチ64が駆動円盤61と他方の従動円盤63との間で離脱解除された状態となっているため、他方の従動円盤63が回転駆動されることはない。なお、ワンウエイクラッチ64の係合体642がスムースなスライドが期待されるピンとされているため、ワンウエイクラッチ64の係合,離脱が円滑に動作される。   When the drive motor 51 of the drive unit 5 is rotated in the forward direction, the drive shaft 52 is also rotationally driven in the forward direction. In the drive transmission mechanism 6, the drive disk 61 is rotated in the forward direction integrally with the drive shaft 52 of the drive unit 5 through the fixing ring 80. At this time, as shown in FIGS. 3, 6, 7, and 12, the engagement body 642 of the one-way clutch 64 of the drive transmission mechanism 6 slides on the inclined surface 641 b of the engagement groove 641 on one driven disk 62. The engaging groove 641 reaches the flat portion 641b and is engaged with the engaging groove 641. That is, the one-way clutch 64 of the drive transmission mechanism 6 is engaged and connected between the drive disk 61 and one driven disk 62, and the one driven disk 62 follows the drive disk 61 in the forward direction. Will be rotated. At this time, since the one-way clutch 64 of the drive transmission mechanism 6 is released from the drive disk 61 and the other driven disk 63, the other driven disk 63 is driven to rotate. Absent. Since the engagement body 642 of the one-way clutch 64 is a pin that is expected to smoothly slide, the engagement and disengagement of the one-way clutch 64 are smoothly operated.

駆動伝達機構6の一方の従動円盤62の正方向への回転駆動は、従動円盤62に取付けられている駆動伝達用スプロケット300の回転駆動となる。そして、駆動伝達用チェーン100,駆動伝達用スプロケット60,回転軸30,スプロケット10を介して、移動用チェーン4のエンドレス状の往復ラインの上側が荷台Bの後方側から前方側へ移動されることになる。   The rotational drive in the forward direction of one driven disk 62 of the drive transmission mechanism 6 becomes the rotational drive of the drive transmission sprocket 300 attached to the driven disk 62. Then, the upper side of the endless reciprocating line of the moving chain 4 is moved from the rear side to the front side of the loading platform B through the drive transmission chain 100, the drive transmission sprocket 60, the rotary shaft 30, and the sprocket 10. become.

駆動伝達機構6の一方の従動円盤62の駆動円盤61に追従した正方向に回転の際には、ロック機構65のボール651がワンウエイクラッチ64の係合体642の環状溝642bに弾圧係合している。従って、回転の応力や周囲の振動が伝導しても、駆動伝達機構6のワンウエイクラッチ64の係合接続が不測に解除されることはない。   When the drive transmission mechanism 6 rotates in the forward direction following the drive disk 61 of one driven disk 62, the ball 651 of the lock mechanism 65 is elastically engaged with the annular groove 642b of the engagement body 642 of the one-way clutch 64. Yes. Therefore, even if rotational stress and ambient vibration are conducted, the engagement connection of the one-way clutch 64 of the drive transmission mechanism 6 is not unexpectedly released.

この結果、貨物支持体3とコンベア1の繰出し先端とが荷台Bの後方側から前方側へ確実に移動され、コンベア1が荷揚げされて積載された貨物を移動させて配設面に展開されることになる。   As a result, the cargo support 3 and the leading end of the conveyor 1 are reliably moved from the rear side to the front side of the loading platform B, and the conveyor 1 is unloaded and the loaded cargo is moved and deployed on the arrangement surface. It will be.

このとき、コンベア1の繰出しにともなってローラ2が回転し、駆動伝達用スプロケット8,駆動伝達用チェーン200を回転させて、駆動伝達用スプロケット400と駆動伝達機構6の他方の従動円盤63とを逆方向へ回転させることになる。ただし、駆動伝達機構6のワンウエイクラッチ64が駆動円盤61と他方の従動円盤63との間で離脱解除された状態となっているため、一方の従動円盤62の正方向への回転駆動が影響を受けることがない。   At this time, as the conveyor 1 is fed, the roller 2 rotates to rotate the drive transmission sprocket 8 and the drive transmission chain 200, so that the drive transmission sprocket 400 and the other driven disk 63 of the drive transmission mechanism 6 are connected. It will be rotated in the opposite direction. However, since the one-way clutch 64 of the drive transmission mechanism 6 is released from the drive disk 61 and the other driven disk 63, the rotational drive in the positive direction of the one driven disk 62 has an influence. I do not receive it.

駆動部5の駆動モータ51が逆方向に回転駆動されると、駆動軸52も逆方向に回転駆動されることになる。そして、駆動伝達機構6は、固定リング80を介して駆動円盤61が駆動部5の駆動軸52と一体的に逆方向に回転されることになる。このとき、図8,図9,図12に示すように、駆動伝達機構6のワンウエイクラッチ64の駆動円盤61と一方の従動円盤62との間での係合接続が解除される。なお、駆動伝達機構6のワンウエイクラッチ64の係合溝641に平坦部分641bが設けられて係合体642との間にあそびが確保されるため、ワンウエイクラッチ64の係合溝641,係合体642の係合の機械的なデッドロックが避けられ円滑な離脱が保障される。   When the drive motor 51 of the drive unit 5 is rotationally driven in the reverse direction, the drive shaft 52 is also rotationally driven in the reverse direction. In the drive transmission mechanism 6, the drive disk 61 is rotated integrally with the drive shaft 52 of the drive unit 5 in the reverse direction via the fixing ring 80. At this time, as shown in FIGS. 8, 9, and 12, the engagement connection between the drive disk 61 of the one-way clutch 64 of the drive transmission mechanism 6 and the one driven disk 62 is released. Since the flat portion 641b is provided in the engagement groove 641 of the one-way clutch 64 of the drive transmission mechanism 6 to ensure play between the engagement body 642, the engagement groove 641 of the one-way clutch 64 and the engagement body 642 Engagement mechanical deadlock is avoided and smooth disengagement is guaranteed.

そして、図4,図10,図11,図12に示すように、駆動伝達機構6のワンウエイクラッチ64の係合体642が係合溝641の傾斜面641bを滑り他方の従動円盤63に設けられている係合溝641の平坦部分641bに至って係合溝641に係止される。即ち、駆動伝達機構6のワンウエイクラッチ64が駆動円盤61と他方の従動円盤63との間で係合接続された状態となって、他方の従動円盤63が駆動円盤61に追従して逆方向に回転されることになる。なお、このとき、駆動伝達機構6のワンウエイクラッチ64が駆動円盤61と一方の従動円盤62との間で離脱解除された状態となっているため、一方の従動円盤62が回転駆動されることはない。なお、ワンウエイクラッチ64の係合体642がスムースなスライドが期待されるピンとされているため、ワンウエイクラッチ64の係合,離脱が円滑に動作される。   4, 10, 11, and 12, the engagement body 642 of the one-way clutch 64 of the drive transmission mechanism 6 slides on the inclined surface 641 b of the engagement groove 641 and is provided on the other driven disk 63. The engagement groove 641 reaches the flat portion 641b and is engaged with the engagement groove 641. That is, the one-way clutch 64 of the drive transmission mechanism 6 is engaged and connected between the drive disk 61 and the other driven disk 63, and the other driven disk 63 follows the drive disk 61 in the reverse direction. Will be rotated. At this time, since the one-way clutch 64 of the drive transmission mechanism 6 is released from the drive disk 61 and the one driven disk 62, the one driven disk 62 is driven to rotate. Absent. Since the engagement body 642 of the one-way clutch 64 is a pin that is expected to smoothly slide, the engagement and disengagement of the one-way clutch 64 are smoothly operated.

駆動伝達機構6の他方の従動円盤63の逆方向への回転駆動は、従動円盤63に取付けられている駆動伝達用スプロケット400の回転駆動となる。そして、駆動伝達用チェーン200,駆動伝達用スプロケット8を介して、ローラ2がコンベア1の巻取り方向へ回転されることになる。   The rotational drive in the reverse direction of the other driven disk 63 of the drive transmission mechanism 6 becomes the rotational drive of the drive transmission sprocket 400 attached to the driven disk 63. Then, the roller 2 is rotated in the winding direction of the conveyor 1 via the drive transmission chain 200 and the drive transmission sprocket 8.

駆動伝達機構6の他方の従動円盤63の駆動円盤61に追従した逆方向に回転の際には、ロック機構65のボール651がワンウエイクラッチ64の係合体642の環状溝642bに弾圧係合している。従って、回転の応力や周囲の振動が伝導しても、駆動伝達機構6のワンウエイクラッチ64の係合接続が不測に解除されることはない。   When the drive transmission mechanism 6 rotates in the reverse direction following the drive disk 61 of the other driven disk 63, the ball 651 of the lock mechanism 65 is elastically engaged with the annular groove 642b of the engagement body 642 of the one-way clutch 64. Yes. Therefore, even if rotational stress and ambient vibration are conducted, the engagement connection of the one-way clutch 64 of the drive transmission mechanism 6 is not unexpectedly released.

この結果、コンベア1がローラ2のローラ本体21に巻取られ、貨物支持体3とコンベア1の繰出し先端とが荷台Bの前方側から後方側へ移動され、コンベア1が積載されている貨物が荷台Bの後方側へ移動される。   As a result, the conveyor 1 is wound around the roller main body 21 of the roller 2, the cargo support 3 and the feeding tip of the conveyor 1 are moved from the front side to the rear side of the loading platform B, and the cargo loaded with the conveyor 1 is moved. It is moved to the rear side of the loading platform B.

このとき、コンベア1の巻取りにともなって、貨物支持体3に引張られた移動用チェーン4が前述と逆の方向へ移動し、スプロケット10,回転軸30,駆動伝達用スプロケット60,駆動伝達用チェーン100を回転させて、駆動伝達用スプロケット300と駆動伝達機構6の一方の従動円盤62とを正方向へ回転させることになる。ただし、駆動伝達機構6のワンウエイクラッチ64が駆動円盤61と一方の従動円盤62との間で離脱解除された状態となっているため、他方の従動円盤63の逆方向への回転駆動が影響を受けることがない。   At this time, as the conveyor 1 is wound up, the moving chain 4 pulled by the cargo support 3 moves in the opposite direction to the above, and the sprocket 10, the rotating shaft 30, the drive transmission sprocket 60, and the drive transmission. The chain 100 is rotated to rotate the drive transmission sprocket 300 and one driven disk 62 of the drive transmission mechanism 6 in the forward direction. However, since the one-way clutch 64 of the drive transmission mechanism 6 is released from the drive disk 61 and one driven disk 62, the rotational drive in the reverse direction of the other driven disk 63 has an effect. I do not receive it.

以上のように、ローラ2,移動用チェーン4を駆動する駆動部5が共通化され、駆動伝達機構6によって駆動の自動的な切換えがなされる。   As described above, the roller 2 and the drive unit 5 that drives the moving chain 4 are made common, and the drive transmission mechanism 6 automatically switches the drive.

以上、図示した形態の外に、移動用チェーン4を移動する各部と連係して貨物支持体3を積極的に移動駆動する機構を追加することも可能である。   As described above, it is also possible to add a mechanism for actively moving and driving the cargo support 3 in cooperation with each part that moves the moving chain 4 in addition to the illustrated form.
