Description

本発明は商品を搬送する搬送コンベアに係り、更に詳しくはベルトコンベアで、無端状ベルトの交換を容易にする技術に関する。   The present invention relates to a conveyor for conveying products, and more particularly to a technique for facilitating replacement of an endless belt with a belt conveyor.

一般的に搬送ベルトコンベアの無端状ベルト(平ベルト)は、経年変化に伴い破損や汚れなどが生じた場合、交換することになる。
しかし、従来のベルトコンベヤは、無端状ベルトを支持するローラを両端に支持したフレームが脚部材に両支持で連結支持されている為、ベルト交換のために無端状ベルトだけをコンベアフレームから外すことは困難である。即ち、フレームと脚部材を連結しているボルト・ナットを工具を用いて外すなどしなければならない。
Generally, an endless belt (flat belt) of a conveyor belt conveyor is replaced when it is damaged or soiled with aging.
However, in the conventional belt conveyor, since the frame supporting the rollers supporting the endless belt at both ends is coupled and supported to the leg member by both supports, only the endless belt is removed from the conveyor frame for belt replacement. It is difficult. That is, the bolts and nuts connecting the frame and the leg members must be removed using a tool.

そこで、ベルトコンベヤにおいて無端状ベルトの着脱を、フレームに連設した補助フレームを折り曲げることにより行なうようにしたものが提案されている(例えば、特許文献1参照)。   Therefore, there has been proposed a belt conveyor in which an endless belt is attached and detached by bending an auxiliary frame continuously provided on the frame (see, for example, Patent Document 1).

しかしながら、特許文献1に記載のものは補助フレームを折り曲げる前に、装置に付随するハンドルや側板を外すことが必要で、無端状ベルトを交換する作業全体としては工具を必要とし、簡単に工具無しでベルト交換の作業をすることはできないという問題があった。   However, the one described in Patent Document 1 requires that the handle and side plate attached to the apparatus be removed before the auxiliary frame is bent, and the entire operation for replacing the endless belt requires a tool, and there is no tool easily. However, there was a problem that the belt could not be changed.

また、フレーム部を外し、再度固定する際に無端状ベルトを駆動するための駆動部とフレーム部との位置関係を調整する必要があり、結果的にベルト交換を容易に行なうことができないという問題があった。   Moreover, it is necessary to adjust the positional relationship between the drive unit and the frame unit for driving the endless belt when the frame unit is removed and fixed again, and as a result, the belt cannot be easily replaced. was there.

更に、搬送ベルトコンベアが複数台連設されているような場合、それぞれのコンベアの無端状ベルトを駆動するための駆動源を必要としていたので、構造が複雑でコストアップにつながるという問題があった。   Furthermore, when a plurality of conveyor belt conveyors are connected in series, a drive source for driving the endless belts of each conveyor is required, so that there is a problem that the structure is complicated and the cost is increased. .

上記手段によれば、可動部と連動自在な係止片が設けられていることで、コンベア部がフレーム部に設置されている状態では、支持杆に係止片が係着してコンベア部はフレーム部に対して固定保持される。そして可動部をコンベア長を縮める方向に移動した時、可動部の移動に連動して係止片が回動されて支持杆との係着が解除され、コンベア部の係合孔は支持杆より上方に外れ、フレーム部から分離可能となる。
The separation means is disposed in the vicinity of the support hole provided in the frame part, an engagement hole provided in the conveyor part detachable in the vertical direction with respect to the support bar, and the support hole. The engaging piece is engaged with and disengaged from the hook, and the engaging piece is rotated in conjunction with the movement of the movable portion to be engaged with and disengaged from the support hook (claim 2).
According to the above means, the locking piece that can be interlocked with the movable portion is provided, so that when the conveyor portion is installed on the frame portion, the locking piece is engaged with the support rod and the conveyor portion is It is fixedly held with respect to the frame part. When the movable part is moved in the direction of shortening the conveyor length, the locking piece is rotated in conjunction with the movement of the movable part to release the engagement with the support rod. It comes off and can be separated from the frame.

前記コンベア部には、前記可動部をコンベア長を縮める方向に移動させた時、その短縮状態に固定する固定手段を設けたことを特徴とする(請求項3)。

It is formed by the recessed part provided continuously (Claim 4).
According to the above means, the operation of contracting the movable portion against the urging force and the operation of fixing in the contracted state can be performed as a series of operations.

前記コンベア部の無端状ベルトを駆動回転する駆動源はフレーム部側に装備されるが、その具体的構成の一例は、前記コンベア部の可動部を設けた側とは反対側に、無端状ベルトの一方を支持するローラを駆動するタイミングベルトを設け、このコンベア部を前記フレーム部に載架固定した時、該フレーム部に設けた駆動手段が前記タイミングベルトと当接して該タイミングベルトを駆動回転し、無端ベルトを回転するようにする(請求項5)。   A drive source for driving and rotating the endless belt of the conveyor unit is provided on the frame unit side. An example of a specific configuration thereof is an endless belt on the side opposite to the side where the movable unit of the conveyor unit is provided. A timing belt for driving a roller that supports one of the belts is provided, and when the conveyor unit is mounted and fixed on the frame unit, driving means provided on the frame unit abuts on the timing belt to drive and rotate the timing belt. Then, the endless belt is rotated (claim 5).

上記手段によれば、コンベア部をフレーム部に載架固定するだけで、コンベア部に設けたタイミングベルトにフレーム部側に設けた駆動手段の回転体(プーリ)が接触し、その回転体の回転によりタイミングベルトが回転され、最終的に無端状ベルトを支持するローラが回転されて無端状ベルトが回転される。   According to the above means, the rotating body (pulley) of the driving means provided on the frame portion side comes into contact with the timing belt provided on the conveyor portion only by mounting and fixing the conveyor portion on the frame portion, and the rotating body rotates. As a result, the timing belt is rotated, and finally the roller supporting the endless belt is rotated to rotate the endless belt.

前記コンベア部はフレーム部に対して1対1で装着される形態に限らず、フレーム部に複数のコンベヤ部を直列に連設装着するようにしてもよく、その場合は一つの駆動源で全てのコンベア部の無端状ベルトを駆動回転する。
例えば、前記コンベア部を載架するフレーム部に、無端状ベルトを巻装した第2のコンベヤ部を前記コンベア部と直列に連設して載架し、その第2コンベア部の無端ベルトは前記コンベア部の無端ベルトの回転を駆動源としフレーム部に設けた動力伝達手段を介して駆動するように構成する(請求項6)。
その具体例は、前記フレーム部の動力伝達手段をタイミングベルトで構成し、そのタイミングベルトに、前記コンベア部の無端ベルトを支持するローラの軸線上に設けた歯付プーリと、第2のコンベア部の無端ベルトを支持するローラの軸線上に設けた歯付プーリを当接係合させたことを特徴とする(請求項7)。
The conveyor unit is not limited to a configuration in which the conveyor unit is mounted on a one-to-one basis, and a plurality of conveyor units may be mounted in series on the frame unit. The endless belt of the conveyor section is driven and rotated.
For example, a second conveyor unit, in which an endless belt is wound around a frame unit on which the conveyor unit is mounted, is placed in series with the conveyor unit, and the endless belt of the second conveyor unit is The rotation of the endless belt of the conveyor unit is used as a drive source, and it is configured to be driven through power transmission means provided in the frame unit.
The specific example is that the power transmission means of the frame part is constituted by a timing belt, and a toothed pulley provided on the axis of a roller supporting the endless belt of the conveyor part on the timing belt, and a second conveyor part A toothed pulley provided on the axis of a roller that supports the endless belt is abutted and engaged (claim 7).

上記手段によれば、一つの駆動源で複数のコンベア部の無端状ベルトを駆動することができるので、構造が簡単で低コストに抑えることができる。   According to the above means, the endless belts of the plurality of conveyor units can be driven by one drive source, so that the structure is simple and the cost can be reduced.

また、前記フレーム部の動力伝達手段を構成するタイミングベルトの設置箇所に、前記コンベア部と第2のコンベア部との間に位置して搬送ローラを横架配置し、その搬送ローラを前記タイミングベルトとの当接係合により回転可能に構成する(請求項8)。
上記手段によれば、2台のコンベアの連設部に介在した搬送ローラを、コンベア部を駆動する動力伝達手段を利用して回転させることが出来る。
In addition, a conveying roller is disposed horizontally between the conveyor unit and the second conveyor unit at an installation position of the timing belt constituting the power transmission means of the frame unit, and the conveying roller is disposed on the timing belt. And is configured to be rotatable by abutment engagement.
According to the said means, the conveyance roller interposed in the connection part of the two conveyors can be rotated using the power transmission means which drives a conveyor part.

本発明の搬送コンベアは請求項1、2記載の構成により、可動部を移動してコンベア部の無端状ベルトの張力を緩めることでコンベア部とフレーム部とを分離することができる。そして請求項3の構成により、分離したコンベア部においては前記移動した可動部を固定することでコンベア長が短くなり、無端状ベルトを容易に外すことができる。また、可動部の固定を解除するだけで緩んだ張力は元に戻る為、張力の調整が不要になる。
又、請求項4記載の構成により、可動部を固定する動作を、コンベア長を縮める動作の一連の動作として行なうことができる。従って、コンベア部をフレーム部から外すための操作と、外したコンベア部から無端状ベルトを外すための可動部を固定する操作を容易に行なうことができる。
With the configuration according to the first and second aspects, the conveyor according to the present invention can separate the conveyor portion and the frame portion by moving the movable portion and releasing the tension of the endless belt of the conveyor portion. According to the third aspect of the present invention, in the separated conveyor unit, the length of the conveyor is shortened by fixing the moved movable unit, and the endless belt can be easily removed. In addition, the tension that has been loosened is restored by simply releasing the fixing of the movable part, so that it is not necessary to adjust the tension.
According to the fourth aspect of the present invention, the operation for fixing the movable portion can be performed as a series of operations for shortening the conveyor length. Therefore, an operation for removing the conveyor unit from the frame unit and an operation for fixing the movable unit for removing the endless belt from the removed conveyor unit can be easily performed.

更に、請求項5記載の構成により、コンベア部をフレーム部に載架固定するだけで、無端状ベルトを回転できる状態に確立できる。しかも、タイミングベルトと駆動手段(プーリ)との位置関係は、前記したようにコンベア部をフレーム部を載架固定するだけで確立される為、位置調整は不要で便利である。
また、請求項6、7記載の構成により、一つの駆動源で複数のコンベア部の無端状ベルトを駆動することができるので、構造が簡単で低コストに抑えることができる。
Furthermore, according to the configuration of the fifth aspect, it is possible to establish a state in which the endless belt can be rotated only by mounting and fixing the conveyor unit on the frame unit. Moreover, since the positional relationship between the timing belt and the driving means (pulley) is established simply by mounting and fixing the conveyor portion to the frame portion as described above, position adjustment is unnecessary and convenient.
Moreover, since the endless belts of a plurality of conveyor units can be driven by a single drive source, the structure can be simplified and the cost can be reduced.

又、請求項8記載の構成により、直列に連設するコンベア部間に配置した搬送ローラも、コンベア部を駆動する駆動源で駆動できるため、複数の駆動源を装備する必要がない。従って、搬送コンベア全体の構成が簡単となり、コストを抑えることができる。   Further, according to the configuration of the eighth aspect, since the conveying roller disposed between the conveyor units arranged in series can be driven by the driving source for driving the conveyor unit, it is not necessary to equip a plurality of driving sources. Therefore, the configuration of the entire transfer conveyor is simplified, and the cost can be suppressed.

本発明に係る搬送コンベアは、所定間隔を置いて架設した2本のローラに亘って無端状ベルトを一定の張力を保持して巻回したコンベア部と、該コンベア部を分離可能に載承するフレーム部とからなり、そのフレーム部には前記コンベア部の無端状ベルトを駆動する駆動手段を備え、コンベア部は一側部にコンベヤ長を付勢力に抗して縮ませ、無端状ベルトに作用する張力を弱めることが可能な可動部を備えている。   The conveyor according to the present invention rests on a conveyor unit in which an endless belt is wound around two rollers installed at a predetermined interval while maintaining a constant tension, and the conveyor unit is separable. The frame part is provided with a driving means for driving the endless belt of the conveyor part, and the conveyor part is contracted against the urging force on one side part to act on the endless belt. It has a movable part that can weaken the tension.

以下、本発明の実施の形態を図面に基づいて説明する。
図1乃至図5は、フレーム部に対して長尺一本物のコンベア部が装着された搬送コンベアで、Aは無端状ベルトを巻装したコンベア部、Bは前記コンベア部Aの無端状ベルトを駆動回転する駆動手段を備えたフレーム部で、コンベア部Aはフレーム部Bに対して分離着脱可能に載架されている。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIGS. 1 to 5 are conveying conveyors in which a long single conveyor unit is mounted on a frame unit, A is a conveyor unit wound with an endless belt, and B is an endless belt of the conveyor unit A. The conveyor part A is detachably mounted on the frame part B in a frame part having driving means for driving and rotating.

コンベア部Aは、コンベア長(無端状ベルトを巻回支持する左右のローラ間の距離)を長短調節可能に構成した枠体1と、その枠体1の長手方向両側に横架支持したローラ2,2’と、その左右一対のローラ2,2’に亘って巻回した無端状ベルト3と、前記枠体1に架設した一方のローラ2(図面では左側のローラ)に回転力を付与する回転伝達ベルト(タイミングベルト)4を備えて構成されている。   The conveyor section A includes a frame body 1 that is configured such that the length of the conveyor (the distance between the left and right rollers that support and wind the endless belt) can be adjusted, and a roller 2 that is horizontally supported on both longitudinal sides of the frame body 1. , 2 ′, the endless belt 3 wound around the pair of left and right rollers 2, 2 ′, and one of the rollers 2 (left roller in the drawing) provided on the frame body 1. A rotation transmission belt (timing belt) 4 is provided.

前記枠体1は、使用時のコンベア長より短い長さの固定枠5と、その固定枠5の長手方向の一側に該長手方向に沿って左右スライド可能に連設した可動部6とで構成され、前記固定枠5の可動部6を連設した側とは反対側の端部にローラ2が回転可能に架設され、可動部6の側端にローラ2’が回転可能に架設されている。
前記固定枠5は、側板部5aの上縁に水平板部5bを略直角に屈曲形成した前後一対の枠板5’を所定の間隔を置いて対向配置し、これを連結杆7で連結して構成されている。
前後一対の枠板5’の水平板部5b相互の間隔(溝幅)は、左右のローラ2,2’に亘って巻回する無端状ベルト3の裏側中央に設けられるリブ3’が嵌合する幅とし、これにより無端状ベルト3の蛇行走行を防止するように構成されている。又、上記ローラ2,2’のローラ幅の略中央位置外周面には無端状ベルト3のリブ3’が嵌合する溝28が凹設されており、これにより無端状ベルト3の蛇行走行を防止し得るようになっている。
The frame 1 is composed of a fixed frame 5 having a length shorter than the conveyor length in use, and a movable portion 6 continuously provided on one side in the longitudinal direction of the fixed frame 5 so as to be slidable in the left-right direction along the longitudinal direction. The roller 2 is rotatably mounted on the end of the fixed frame 5 opposite to the side where the movable portion 6 is connected, and the roller 2 ′ is rotatably mounted on the side end of the movable portion 6. Yes.
The fixed frame 5 has a pair of front and rear frame plates 5 ′ formed by bending a horizontal plate portion 5 b at a substantially right angle at the upper edge of the side plate portion 5 a so as to be opposed to each other with a predetermined interval. Configured.
The distance (groove width) between the horizontal plate portions 5b of the pair of front and rear frame plates 5 'is fitted with a rib 3' provided at the center on the back side of the endless belt 3 wound around the left and right rollers 2, 2 '. Thus, the endless belt 3 is prevented from running meandering. Further, a groove 28 into which the rib 3 'of the endless belt 3 is fitted is formed in the outer peripheral surface of the roller 2 or 2' at a substantially central position of the roller width, thereby allowing the endless belt 3 to meander. It can be prevented.

可動部6は、前後一対の側板6aを、前記した固定枠5における前後の側板部間に嵌合し得る間隔で平行に配置し、連結杆8で一体的に連結して構成され、その可動部6のローラ2’を架設した側とは反対側が前記固定枠5の側板部5aに対して左右スライド可能に連結されている。
固定枠5に対する可動部6のスライド構造は、固定枠5の前後の側板部5aに長孔部9を対峙して形成し、他方、可動部6の側板6aには前記長孔部9に嵌合する案内ピン10と掛止杆11が間隔を置いて取り付けられている。尚、案内ピン10を前後独立した形態、掛止杆11を前後の側板に亘って架設した1本物で構成してあるが、両者とも独立した形態としたり、1本物とすることは任意である。
又、前記長孔部9の開口長さは、可動部6を移動してコンベア長を短くし、左右のローラ2,2’に亘って巻回された無端状ベルト3に弛みが生じ、該無端状ベルト3の取り外しを容易に行なうことができる長さとする。
The movable portion 6 is configured by arranging a pair of front and rear side plates 6a in parallel at intervals that can be fitted between the front and rear side plate portions of the fixed frame 5, and integrally connecting them with a connecting rod 8. The side of the portion 6 opposite to the side where the roller 2 ′ is installed is connected to the side plate portion 5 a of the fixed frame 5 so as to be slidable in the left-right direction.
The sliding structure of the movable part 6 with respect to the fixed frame 5 is formed by opposing the long hole part 9 to the side plate part 5 a before and after the fixed frame 5, while the side plate 6 a of the movable part 6 is fitted in the long hole part 9. The mating guide pin 10 and the latching rod 11 are attached at an interval. In addition, although the guide pin 10 is comprised by the one thing which carried out the front-and-rear independent form and the latching rod 11 was extended over the front and back side plates, both can be made into the independent form, or it is arbitrary. .
Further, the opening length of the long hole portion 9 moves the movable portion 6 to shorten the conveyor length, and the endless belt 3 wound around the left and right rollers 2 and 2 ′ is slackened, The length is such that the endless belt 3 can be easily removed.

そして、前記固定枠5の側板部5aにおける長孔部9よりコンベア長の中心寄り方向位置にブラケット12を固着し、そのブラケット12の通孔12’に案内板13を移動可能に挿通すると共に、該案内板13の一側部は前記可動部6の案内ピン10に連結し、他側部は後述する分離手段に連結されている。そして、案内板13における案内ピン10近傍に固着したスプリング受け14と前記ブラケット12との間にはコイルスプリング15が弾圧装着されている。それにより、可動部6の案内ピン10と掛止杆11は前記コイルスプリング15の弾発力で前記長孔部9内を固定枠5の側端側(図面では右方向)に向けて押動スライドされ、コンベア部Aは所定のコンベア長に確立される。従って、前記可動部6をコイルスプリング15の弾発力に抗して押動すれば、案内ピン10と掛止杆11は長孔部9内を固定枠5の中心方向に向かって移動し、コンベア長は短くなる。   Then, the bracket 12 is fixed to a position closer to the center of the conveyor length than the long hole portion 9 in the side plate portion 5a of the fixed frame 5, and the guide plate 13 is movably inserted into the through hole 12 ′ of the bracket 12, One side portion of the guide plate 13 is connected to the guide pin 10 of the movable portion 6, and the other side portion is connected to separation means described later. A coil spring 15 is elastically mounted between the spring receiver 14 fixed to the guide plate 13 near the guide pin 10 and the bracket 12. Thereby, the guide pin 10 and the latching rod 11 of the movable portion 6 are pushed toward the side end side (right direction in the drawing) of the fixed frame 5 by the elastic force of the coil spring 15. The conveyor part A is established to a predetermined conveyor length. Therefore, if the movable part 6 is pushed against the elastic force of the coil spring 15, the guide pin 10 and the latching rod 11 move in the elongated hole part 9 toward the center of the fixed frame 5, The conveyor length is shortened.

上記可動部6の移動を所定の移動位置(短縮した位置)で固定する固定手段Cは、前記長孔部9の長さ方向の中程位置から略直角下向きに連通形成した凹部16と、前記可動部6に架設した掛止杆11とで構成され、凹部16に掛止杆11が嵌入係合することで可動部6の移動固定が保持される。
長孔部9に連絡する凹部11の形成位置は、可動部6を長孔部9の内側端方向に押動し、案内ピン10が該長孔部9の内側端近傍位置に位置した時、該案内ピン10を中心として可動部6が下向きに回動し、掛止杆11が嵌合する位置とする。
The fixing means C for fixing the movement of the movable portion 6 at a predetermined movement position (shortened position) includes a concave portion 16 formed so as to communicate downward at a substantially right angle from a middle position in the length direction of the long hole portion 9, and The movable hook 6 is constructed by the hooking rod 11 installed on the movable portion 6, and the movable portion 6 is held fixed by being engaged with the concave portion 16.
The position where the concave portion 11 connected to the long hole portion 9 is formed is such that when the movable portion 6 is pushed toward the inner end of the long hole portion 9 and the guide pin 10 is positioned near the inner end of the long hole portion 9, The movable portion 6 rotates downward about the guide pin 10 and is set to a position where the latch rod 11 is fitted.

又、前記固定枠5を構成する前後の側板部5aには、フレーム部Bの長手方向二箇所に設けた支持杆26,26’に対して上方から嵌合し得る係合孔17,17’が切欠き形成されており、その内一方の係合孔17は略L字形に形成して、真っ直ぐ上方に持ち上げてはフレーム部Bから外せないようにしてある。   In addition, the front and rear side plate portions 5a constituting the fixed frame 5 are engaged holes 17, 17 'that can be fitted from above to support rods 26, 26' provided at two locations in the longitudinal direction of the frame portion B. Is formed in a substantially L-shape so that it cannot be removed from the frame portion B by being lifted straight upward.

そして、もう一方の係合孔17’の側近にはコンベア部Aとフレーム部Bとの係着を、前記可動部6の移動に連動して係脱を切換える分離手段Dが設けられている。
その分離手段Dは、前記係合孔17’の側近に回動可能に軸支した係止片18と、その係止片18を回動操作する前記案内板13とで構成されている。即ち、可動部6の案内ピン10に連結された案内板13の他側部を前記ブラケット12を貫通して反対側に突出させ、その突出部13’にガイド溝19を形成し、そのガイド溝19に前記係止片18の側面に取り付けたピン20を嵌合すると共に、該ピン20と前記ブラケット12とに亘ってスプリング21を張設する。それにより、係止片18はスプリング21の引張力で支持杆26’に対し係着する方向に常時付勢され、コンベア部Aとフレーム部Bの係合状態が保持される。そして、可動部6をコンベ長を縮める方向に押動した時、該可動部6と一緒に移動する案内板13のガイド溝19の孔縁で係止片18のピン20が押動され、それにより係止片18は固定枠との軸支部を中心として支持杆から外れる方向に回動され、コンベア部Aとフレーム部Bの分離を可能にする。
In the vicinity of the other engagement hole 17 ′, separation means D is provided for switching engagement / disengagement between the conveyor part A and the frame part B in conjunction with the movement of the movable part 6.
The separating means D is composed of a locking piece 18 pivotally supported in the vicinity of the engagement hole 17 ′ and the guide plate 13 for rotating the locking piece 18. That is, the other side portion of the guide plate 13 connected to the guide pin 10 of the movable portion 6 penetrates the bracket 12 and protrudes to the opposite side, and a guide groove 19 is formed in the protrusion portion 13 ′. A pin 20 attached to the side surface of the locking piece 18 is fitted to the pin 19 and a spring 21 is stretched between the pin 20 and the bracket 12. As a result, the locking piece 18 is constantly urged in the direction to be engaged with the support rod 26 ′ by the tensile force of the spring 21, and the engaged state of the conveyor part A and the frame part B is maintained. When the movable part 6 is pushed in the direction of shortening the conveyor length, the pin 20 of the locking piece 18 is pushed by the hole edge of the guide groove 19 of the guide plate 13 that moves together with the movable part 6. As a result, the locking piece 18 is rotated in a direction away from the support rod about the shaft support portion with the fixed frame, and the conveyor portion A and the frame portion B can be separated.

又、固定枠5のローラ2と可動部6のローラ2’に亘って巻回した無端状ベルト3はローラ2の駆動回転により回転されるが、そのローラ2にフレーム部B側に装備した駆動手段の回転力を伝達する回転伝達ベルト(タイミングベルト)4が、該ローラ2と固定枠5の側板部5aとの間に配置されている。
上記回転伝達ベルト4は両面歯付きのタイミングベルトで、ローラ2の軸上に固着した歯付プーリ22とその歯付プーリ22の位置よりコンベア長の中央方向へ所定間隔をおいて軸支した歯付プーリ23,23’とに亘って巻回装着されている。そして、コンベア部Aをフレーム部Bに載架定着した時、歯付プーリ22と歯付プーリ23’間の回転伝達ベルト4の外周面がフレーム部B側の駆動手段の歯付伝達プーリ27bの外周面に押圧当接され、該歯付伝達プーリ27bの回転力で回転伝達ベルト4が回転される。
The endless belt 3 wound around the roller 2 of the fixed frame 5 and the roller 2 'of the movable part 6 is rotated by the driving rotation of the roller 2, and the driving provided to the roller 2 on the frame part B side. A rotation transmission belt (timing belt) 4 for transmitting the rotational force of the means is disposed between the roller 2 and the side plate portion 5 a of the fixed frame 5.
The rotation transmission belt 4 is a timing belt with double-sided teeth, and a toothed pulley 22 fixed on the shaft of the roller 2 and a tooth supported at a predetermined interval from the position of the toothed pulley 22 toward the center of the conveyor length. The pulleys 23 and 23 'are wound around and attached. When the conveyor part A is mounted and fixed on the frame part B, the outer peripheral surface of the rotation transmission belt 4 between the toothed pulley 22 and the toothed pulley 23 'is connected to the toothed transmission pulley 27b of the driving means on the frame part B side. The rotation transmission belt 4 is rotated by the rotational force of the toothed transmission pulley 27b.

上記コンベア部Aを水平に載架支持するフレーム部Bは、前記コンベア部Aを載承保持する載せ枠24と、その載せ枠24を所定高さに支持する脚体25と、コンベア部Aの一方のローラ2を駆動回転する為の駆動手段27とで構成されている。
前記載せ枠24は、前記コンベア部Aの高さと略同じ高さを有した前後一対の側枠24を所定の間隔を置いて平行に対向配置し、その両側枠24aを長手方向に間隔を置いた2箇所を連結杆24bで連結して構成してある。そして、前後一対の側枠24aの内面には前記コンベア部Aの載架位置を規定する支持杆26,26’が内方に向けて水平に突設されている。
The frame part B for horizontally mounting and supporting the conveyor part A includes a mounting frame 24 that supports and holds the conveyor part A, legs 25 that support the mounting frame 24 at a predetermined height, and a conveyor part A. It comprises driving means 27 for driving and rotating one roller 2.
In the mounting frame 24, a pair of front and rear side frames 24 having substantially the same height as the conveyor part A are arranged in parallel to each other with a predetermined interval, and both side frames 24a are spaced in the longitudinal direction. The two locations are connected by a connecting rod 24b. Further, on the inner surfaces of the pair of front and rear side frames 24a, support rods 26 and 26 'for defining the mounting position of the conveyor portion A are provided horizontally and projecting inward.

上記駆動手段27は、モータ27a、歯付伝達プーリ27b、及びモータ27aの出力を歯付伝達プーリ27bに伝達するチェーンやベルト等の伝達帯27cとで構成され、歯付伝達プーリ27bの外径は前記回転伝達ベルト4との接触範囲が広くなるように大径に形成されている。   The driving means 27 includes a motor 27a, a toothed transmission pulley 27b, and a transmission band 27c such as a chain or a belt for transmitting the output of the motor 27a to the toothed transmission pulley 27b. The outer diameter of the toothed transmission pulley 27b. Is formed in a large diameter so that the contact range with the rotation transmission belt 4 is widened.

上記に如く構成した搬送コンベアは、コンベア部Aをフレーム部B上に載架定着することでフレーム部B側に装備されている駆動手段27の歯付伝達プーリ27bとコンベア部Aの回転伝達ベルト4とが当接係合し、歯付伝達プーリ27bの回転で回転伝達ベルト4が回転し、ローラ2が駆動回転され、それによりローラ2,2’に亘って巻回した無端状ベルト3は回転される(図5(a)参照)。
そして、コンベア部Aをフレーム部Bから分離し取り外す時は、ローラ2’を支持した可動部6をコイルスプリング15の弾発力に抗して固定枠5側に押動すると、該可動部6の案内ピン10と掛止杆11は固定枠5の長孔部9内をコンベア長の中心方向に向かって移動し、コンベア長が短くなってローラ2とローラ2’の間隔が狭くなり、無端状ベルト3に作用する張力が弱くなると共に、可動部6の押動で案内板13がスライドされ、フレーム部Bの支持杆26’に係着しているコンベア部Aの係止片18を分離手段Dを作動して分離可能にする。これにより、コンベア部Aはフレーム部Bの支持杆26を中心として上方に回動することで固定枠5の係合孔17’は支持杆26’から外れ、もう一方の係合孔17と支持杆26の係着は該コンベア部A(枠体1)を係合孔17に沿って移動させることで外れる(図5(b)参照)。
The conveyor configured as described above has the conveyor part A mounted on the frame part B and fixed, and the toothed transmission pulley 27b of the driving means 27 and the rotation transmission belt of the conveyor part A are provided on the frame part B side. 4, the rotation transmission belt 4 is rotated by the rotation of the toothed transmission pulley 27 b, the roller 2 is driven to rotate, and the endless belt 3 wound around the rollers 2 and 2 ′ is It is rotated (see FIG. 5A).
When the conveyor part A is separated from the frame part B and removed, the movable part 6 supporting the roller 2 ′ is pushed toward the fixed frame 5 against the elastic force of the coil spring 15. The guide pin 10 and the latching rod 11 move in the elongated hole portion 9 of the fixed frame 5 toward the center of the conveyor length, the conveyor length becomes shorter, the distance between the roller 2 and the roller 2 'becomes smaller, and endless The tension acting on the belt-like belt 3 is weakened, and the guide plate 13 is slid by the pushing of the movable part 6 to separate the locking piece 18 of the conveyor part A engaged with the support rod 26 'of the frame part B. Means D are activated to allow separation. As a result, the conveyor part A pivots upward about the support rod 26 of the frame part B, so that the engagement hole 17 ′ of the fixed frame 5 is disengaged from the support rod 26 ′ and is supported by the other engagement hole 17. The hook 26 is detached by moving the conveyor portion A (frame 1) along the engagement hole 17 (see FIG. 5B).

又、フレーム部Bから外したコンベア部Aにおいて無端状ベルト3を外す場合は、前記した可動部6の押動の行き止まり手前の位置で該可動部6の掛止杆11を長孔部9の途中に連設された固定手段Cの凹部16に嵌入係着させることで、可動部6の移動が固定される。それにより、ローラ2とローラ2’間の間隔は使用状態に比べて狭くなり、その結果無端状ベルト3に作用する張力は弱まり、ベルトには弛みが生じて枠体1から容易に取り外すことが可能となる(図5(c)参照)。
尚、コンベア部Aをフレーム部Bに載架し、可動部6の移動を固定している固定手段Cを該可動部6の回動で解除すれば、コイルスプリング15の弾発力で可動部6は所定位置に押動復帰され、無端状ベルト3に作用する張力も当所の張力に復帰される。
Further, when the endless belt 3 is removed from the conveyor part A removed from the frame part B, the hooking rod 11 of the movable part 6 is inserted into the long hole part 9 at a position just before the end of the pushing of the movable part 6. The movement of the movable portion 6 is fixed by fitting and engaging with the concave portion 16 of the fixing means C provided in the middle. As a result, the distance between the roller 2 and the roller 2 ′ becomes narrower than that in use, and as a result, the tension acting on the endless belt 3 is weakened, the belt is slackened and can be easily removed from the frame 1. This is possible (see FIG. 5C).
If the conveyor part A is mounted on the frame part B and the fixing means C that fixes the movement of the movable part 6 is released by the rotation of the movable part 6, the movable part is moved by the elastic force of the coil spring 15. 6 is pushed back to a predetermined position, and the tension acting on the endless belt 3 is also restored to the tension at this place.

図6乃至図12は、一つのフレーム部B’に、長短二台のコンベア部A’,A”と、それらコンベア部の間に搬送ローラEを配設した搬送コンベアを示し、長短二台のコンベア部A’,A”の構成及びフレーム部B’の構成は、基本的に前記した実施例1と同様である為詳細な説明は省略し、実施例1に存在しない構成、短コンベア部A”における無端状ベルトの駆動機構、搬送ローラEの駆動機構(動力伝達手段F)について説明する。   FIGS. 6 to 12 show a conveyor unit in which two conveyor units A ′, A ″ and conveyor rollers E are arranged between the conveyor units A ′ and A ″ on one frame unit B ′.

Accordingly, when the movable portion 30 is pushed against the urging force in the center direction of the conveyor length, the hooking hole 36 is moved and the engagement hole 35 ′ is opened, and the conveyor portion A ′ becomes the frame portion B ′. It can be separated and removed from.

又、上記可動部30に支持したローラ31’の軸端には歯付プーリ37が一体的に固着されており、この歯付プーリ37は長コンベア部A’をフレーム部B’に載架定着した時該フレーム部B’に装備した動力伝達手段Fと連繋し、無端状ベルト32の回転による歯付プーリ37の回転を動力伝達手段Fに伝達し得るように構成されている。   A toothed pulley 37 is integrally fixed to the shaft end of the roller 31 'supported by the movable portion 30, and the toothed pulley 37 mounts and fixes the long conveyor portion A' to the frame portion B '. At this time, it is connected to the power transmission means F mounted on the frame portion B ′, and is configured to transmit the rotation of the toothed pulley 37 due to the rotation of the endless belt 32 to the power transmission means F.

フレーム部B’に載架する短コンベア部A”は、前記した長コンベア部A’に比べてコンベア長を短くしたもので、固定枠39の一側に可動部40を弾発水平移動可能に連結した枠体38と、固定枠39の側部に支持したローラ41と可動部40の側部に支持したローラ41’とに亘って無端状ベルト42が巻回されて構成されている。
そして、可動部39の移動機構及びフレーム部B’に対する着脱構造は長コンベア部A’と同様である。
尚、長コンベア部A’及び短コンベア部A”における可動部の移動機構は、前記した実施例1と同様である為、実施例1と同一の構成については同一の符号を付し説明は省略する。
The short conveyor part A ″ mounted on the frame part B ′ has a shorter conveyor length than the long conveyor part A ′ described above, and allows the movable part 40 to be moved horizontally on one side of the fixed frame 39. An endless belt 42 is wound around the connected frame 38, the roller 41 supported on the side of the fixed frame 39, and the roller 41 ′ supported on the side of the movable unit 40.
And the moving mechanism of the movable part 39 and the attachment / detachment structure with respect to frame part B 'are the same as that of the long conveyor part A'.
In addition, since the moving mechanism of the movable part in the long conveyor part A ′ and the short conveyor part A ″ is the same as that of the first embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. To do.

上記の如く構成した短コンベア部A”の固定枠39に支持したローラ41の軸端には歯付プーリ43が一体的に固着されており、この歯付プーリ43は該短コンベア部A”をフレーム部B’に載架定着した時、該フレーム部B’に装備した動力伝達手段Fと連繋し、回転力が歯付プーリ43に伝達されるように構成されている。   A toothed pulley 43 is integrally fixed to the shaft end of the roller 41 supported by the fixed frame 39 of the short conveyor section A ″ configured as described above. The toothed pulley 43 is connected to the short conveyor section A ″. When mounted and fixed on the frame part B ′, it is connected to the power transmission means F equipped on the frame part B ′ so that the rotational force is transmitted to the toothed pulley 43.

上記長コンベア部A’と短コンベア部A”を載承するフレーム部B’は、前記した実施例1と同様、長コンベア部A’、短コンベア部A”を載承保持する載せ枠44と、その載せ枠44を所定高さに支持する脚体45と、長コンベア部A’の一方のローラ31を駆動回転する為の駆動手段46とで構成されている。
そして、長コンベア部A’を載承する箇所と短コンベア部A”を載承する箇所との間には、長コンベア部A’から短コンベア部A”へ回転力を伝達する動力伝達手段Fと、その動力伝達手段Fで回転される搬送ローラEが配置されている。
The frame part B ′ for mounting the long conveyor part A ′ and the short conveyor part A ″ is the same as in the first embodiment, the long conveyor part A ′ and the mounting frame 44 for mounting and holding the short conveyor part A ″. The leg frame 45 supports the mounting frame 44 at a predetermined height, and driving means 46 for driving and rotating one roller 31 of the long conveyor section A ′.
And between the place which mounts the long conveyor part A 'and the place which mounts the short conveyor part A ", the power transmission means F which transmits rotational force from the long conveyor part A' to the short conveyor part A" And the conveyance roller E rotated by the power transmission means F is arrange | positioned.

上記動力伝達手段Fは、上流側に配置される長コンベア部A’の無端状ベルト32の回転を下流側に配置される短コンベア部A”の無端状ベルト42に伝達するもので、載せ枠44の内側(長コンベア部A’の歯付プーリ37、短コンベア部A”の歯付プーリ43と対向する側)に、複数(図面では6個)の歯付プーリ47〜52を回転可能に軸支し、それら歯付プーリ47〜52に亘って両面歯付きのタイミングベルト53を巻回して構成してある。そして、その巻回したタイミングベルト53は正面略扁平逆三角形をなし、上側に歯付プーリ37及び歯付プーリ43が当接噛合するように構成されている。
それにより、長コンベア部A’の無端状ベルト32の回転はローラ31’(歯付プーリ37)→タイミングベルト53→(歯付プーリ43)ローラ41と伝達され、短コンベア部A”の無端状ベルト42が回転される(図9参照)。
The power transmission means F transmits the rotation of the endless belt 32 of the long conveyor section A ′ arranged on the upstream side to the endless belt 42 of the short conveyor section A ″ arranged on the downstream side. A plurality (six in the drawing) of toothed pulleys 47 to 52 can be rotated inside 44 (side facing the toothed pulley 37 of the long conveyor portion A ′ and the toothed pulley 43 of the short conveyor portion A ″). A timing belt 53 with double-sided teeth is wound around the pulleys 47 to 52 with a shaft. The wound timing belt 53 is formed in a substantially flat inverted triangle in front and is configured such that the toothed pulley 37 and the toothed pulley 43 are in contact with each other on the upper side.
Thereby, the rotation of the endless belt 32 of the long conveyor portion A ′ is transmitted from the roller 31 ′ (toothed pulley 37) → the timing belt 53 → (toothed pulley 43) roller 41, and the endless shape of the short conveyor portion A ″. The belt 42 is rotated (see FIG. 9).

搬送ローラEは、長コンベア部A’の終端側(ローラ31’)と短コンベア部A”の始端側(ローラ41)との間に位置して載せ枠44内に回転可能に横架し、その搬送ローラEおける前記タイミングベルト53と対応する位置に歯付プーリ54が一体的に固着されている。そして、その歯付プーリ54はタイミングベルト53との噛み合い状態が維持されるようタイミングベルト53に対して押し付けた状態で横架されている。それにより、搬送ローラEはタイミングベルト53の回動で回転される。   The conveying roller E is positioned between the terminal end side (roller 31 ′) of the long conveyor section A ′ and the starting end side (roller 41) of the short conveyor section A ″, and is rotatably mounted in the mounting frame 44. A toothed pulley 54 is integrally fixed to a position corresponding to the timing belt 53 in the conveying roller E. The timing belt 53 is maintained so that the toothed pulley 54 is engaged with the timing belt 53. As a result, the conveying roller E is rotated by the rotation of the timing belt 53.

この実施例2で示す搬送コンベアは、図6,7に示すように、搬送中の商品の底面にラベルを貼付するラベル下貼り装置に有効で、商品を搬送するコンベア(長コンベア部と短コンベア部)の途中に、搬送ローラEを配置し、その搬送ローラEの下方にラベルを搬送するラベル搬送コンベア55を配置した場合、商品を搬送する長コンベア部A’と短コンベア部A”と搬送ローラEの駆動を、フレーム部B’に装備した1個の駆動手段46で駆動することができる。   As shown in FIGS. 6 and 7, the conveyor shown in the second embodiment is effective for an under-labeling apparatus for attaching a label to the bottom surface of a product being conveyed, and conveys the product (long conveyor unit and short conveyor). Part)), when the transport roller E is disposed and the label transport conveyor 55 for transporting the label is disposed below the transport roller E, the long conveyor part A ′ and the short conveyor part A ″ for transporting the product are transported. The roller E can be driven by a single driving means 46 provided in the frame portion B ′.

上記に如く構成した搬送コンベアは、長コンベア部A’と短コンベア部A”をフレーム部B’上に載架定着することでフレーム部B’側に装備されている駆動手段46の歯付伝達プーリと長コンベア部A’の回転伝達ベルト33とが当接係合し、駆動手段46(歯付伝達プーリ)の回転で回転伝達ベルト33が回転し、ローラ31が駆動回転され、それによりローラ31,31’に亘って巻回した無端状ベルト32が回転される。
そして、長コンベア部A’における無端状ベルト32の回転は、ローラ31’((歯付プーリ37)から動力伝達手段Fを介して短コンベア部A”のローラ41(歯付プーリ43)に伝達され、短コンベア部A”の無端状ベルト42が回転される。更に、前記動力伝達手段Fの作動により長コンベア部A’と短コンベア部A”の間に配置して搬送ローラEも駆動回転される(図9参照)。
即ち、一つの駆動手段46で長コンベア部A’の無端状ベルト32と短コンベア部A”の無端状ベルト42と搬送ローラEを同一方向に回転することができる。
The conveying conveyor configured as described above has a toothed transmission of the driving means 46 provided on the frame part B ′ side by mounting and fixing the long conveyor part A ′ and the short conveyor part A ″ on the frame part B ′. The pulley and the rotation transmission belt 33 of the long conveyor section A ′ are brought into contact with each other, and the rotation transmission belt 33 is rotated by the rotation of the driving means 46 (toothed transmission pulley), so that the roller 31 is driven and rotated. The endless belt 32 wound over 31 and 31 'is rotated.
The rotation of the endless belt 32 in the long conveyor section A ′ is transmitted from the roller 31 ′ ((tooth pulley 37) to the roller 41 (tooth pulley 43) of the short conveyor section A ″ via the power transmission means F. Then, the endless belt 42 of the short conveyor portion A ″ is rotated. Further, the power transmission means F is operated to drive and rotate the conveying roller E arranged between the long conveyor portion A ′ and the short conveyor portion A ″. (See FIG. 9).
That is, the endless belt 32 of the long conveyor section A ′, the endless belt 42 of the short conveyor section A ″, and the conveying roller E can be rotated in the same direction by one driving means 46.

そして、長コンベア部A’及び短コンベア部A”をフレーム部B’から分離し取り外す時は、図10に示すように短コンベア部A”のローラ41’を支持した可動部40をコイルスプリング15の弾発力に抗して固定枠39側に押動すると、該可動部40の案内ピン10と掛止杆11は固定枠39の長孔部9内をコンベア長の中心方向に向かって移動し、コンベア長が短くなってローラ41とローラ41’の間隔が狭くなり、無端状ベルト42に作用する張力が弱くなる。そして、可動部40の押動により引掛け孔36が移動して係合孔35’が開放状態になり、フレーム部B’の支持杆34,34’に嵌合する係合孔35,35’は外れ、コンベア部A”はフレーム部B’から分離取り外し自在となる。同様にして長コンベア部A’もフレーム部B’から分離取り外すことができる(図11参照)。   When the long conveyor portion A ′ and the short conveyor portion A ″ are separated from the frame portion B ′ and removed, the movable portion 40 supporting the roller 41 ′ of the short conveyor portion A ″ as shown in FIG. When the guide pin 10 and the latching rod 11 of the movable portion 40 are pushed toward the fixed frame 39 against the elastic force of the guide, the guide pin 10 and the latch rod 11 of the movable portion 40 move in the long hole portion 9 of the fixed frame 39 toward the center of the conveyor length However, the conveyor length is shortened, the interval between the roller 41 and the roller 41 ′ is narrowed, and the tension acting on the endless belt 42 is weakened. Then, when the movable portion 40 is pushed, the hooking hole 36 is moved to open the engagement hole 35 ′, and the engagement holes 35, 35 ′ are fitted into the support rods 34, 34 ′ of the frame portion B ′. The conveyor part A ″ can be separated and removed from the frame part B ′. Similarly, the long conveyor part A ′ can be separated and removed from the frame part B ′ (see FIG. 11).

又、フレーム部B’から外した短コンベア部A”において無端状ベルト42を外す場合は、前記した可動部40の押動の途中で該可動部40の掛止杆11を長孔部9の途中に連設された固定手段Cの凹部16に嵌入係着させることで、可動部40の移動が固定される。それにより、ローラ41とローラ41’間の間隔は使用状態に比べて狭くなり、その結果無端状ベルト42に作用する張力は弱まり、ベルトには弛みが生じて枠体38から容易に取り外すことが可能となる(図10(c)参照)。同様にして、長コンベア部A’の無端状ベルト32を取り外すことができる。
尚、長コンベア部A’及び短コンベア部A”をフレーム部B’に載架し、可動部の移動を固定している固定手段Cを該可動部の回動で解除すれば、コイルスプリング15の弾発力で可動部は所定位置に押動復帰され、無端状ベルトに作用する張力も当所の張力に復帰される。
Further, when the endless belt 42 is removed from the short conveyor part A ″ removed from the frame part B ′, the latch bar 11 of the movable part 40 is moved to the long hole part 9 in the middle of the pushing of the movable part 40. The movement of the movable portion 40 is fixed by being fitted and engaged with the concave portion 16 of the fixing means C provided in the middle, whereby the distance between the roller 41 and the roller 41 ′ is narrower than that in use. As a result, the tension acting on the endless belt 42 is weakened, and the belt is loosened and can be easily removed from the frame 38 (see FIG. 10C). The endless belt 32 can be removed.
If the long conveyor part A ′ and the short conveyor part A ″ are mounted on the frame part B ′ and the fixing means C that fixes the movement of the movable part is released by the rotation of the movable part, the coil spring 15 The movable portion is pushed and returned to a predetermined position by the elastic force, and the tension acting on the endless belt is also restored to the tension at this point.
