According to the fourth aspect of the present invention, the tension of the belt (50) is released by moving the other end (30b) of the support shaft (34) in the transport direction. Here, the other end portion of the support shaft (34) (30b), the movement in the conveying direction by the support member (26) is allowed, with a configuration that is restricted from moving in the vertical direction intersecting the conveying direction When the engagement with the engaging portions (38, 39) by the second operating member (72) is released, the other end portion (30b) of the support shaft (34) is allowed to move in the carrying direction , and is moved in the carrying direction. Since the movement in the intersecting vertical direction is restricted , the belt (50) can be greatly loosened between the conveyance end portions. Therefore, it becomes easy to pull out the belt (50).

本発明は上記各発明の手段をとることにより、無端状のベルトの脱着及び蛇行修正を簡素に構成したベルトコンベヤを提供することができる。 The present invention can provide a belt conveyor in which the endless belt is simply attached and detached and the meandering correction is made by taking the measures of the above-described inventions.

以下に、第１の実施形態について図１〜４を用いて説明する。図１のごとく、搬送方向に向けて立設された長板状の本体フレーム１２にベルトコンベヤ１０が直列に４つ隣接して配設されている。
各ベルトコンベヤ１０には、無端状のベルト５０が第１シャフト３０（回転体）と第２シャフト４０とその下方に配設された駆動シャフト２８によって所定の張力で張られた状
態で走行可能に巻き掛けられている。
各ベルト５０は、本体フレーム１２に配設された夫々のサーボモータ（不図示）の駆動で駆動シャフト２８が同方向に夫々回転駆動されることにより、第１シャフト３０側から第２シャフト４０側に水平に物品を搬送する。即ち、各ベルトコンベヤ１０は、搬送端部が第１シャフト３０と第２シャフト４０付近に形成される。
なお、本実施の形態における各ベルトコンベヤ１０は、実質的に同じであるため、代表して一つのベルトコンベヤについて説明する。
図１、図２のごとく、ベルトコンベヤ１０には、支持板１４が本体フレーム１２から水平方向に延設され、該支持板１４の搬送方向における上流側に第１シャフト３０が配設されると共に下流側に第２シャフト４０が配設されている。
支持板１４の中央部には、吸引用の孔１５が形成されている。孔１５は、不図示の負圧手段に接続されると共にベルト５０に形成された吸引孔５２と連通して、ベルト５０上で搬送時に物品の位置ずれを防ぐために形成されている。
第１シャフト３０は、ベルト５０が巻き掛けられるローラ３２と、該ローラ３２を回転可能に支持する支持シャフト３４を有している。
第１シャフト３０の一端部３０ａとして、ローラ３２から本体フレーム１２側に延出した支持シャフト３４は、支持板１４の一部から搬送方向上流側に平行に張り出した上下一対の平板状の案内板２４の間に配設されることで、上下方向の移動が規制された状態で支持されている。
また、ローラ３２を挟んで一端部３０ａとは相反する側の第１シャフト３０の他端部３０ｂにおいては、支持シャフト３４に装着された後述するスライド部材３８が、支持板１４の一部から搬送方向上流側に平行に張り出した上下一対の平板状の第２の案内板２６（支持体）の間に配設されることで、上下方向の移動が規制された状態で支持されている。
なお、これらの案内板２４、２６によって支持シャフト３４は水平に支持されており、第１シャフト３０の一端部３０ａには蛇行調節手段が装備され、第１シャフト３０の他端部３０ｂにはベルト脱着手段が装備されている。 Below, 1st Embodiment is described using FIGS. 1-4. As shown in FIG. 1, four belt conveyors 10 are arranged adjacent to each other in a long plate-like main body frame 12 erected in the conveying direction.
In each belt conveyor 10, an endless belt 50 can run in a state of being tensioned with a predetermined tension by a first shaft 30 (rotating body), a second shaft 40, and a drive shaft 28 disposed below the first shaft 30 (rotating body). It is wrapped around.
Each belt 50 is driven from the first shaft 30 side to the second shaft 40 side by the drive shaft 28 being rotated in the same direction by the drive of each servo motor (not shown) disposed on the main body frame 12. Convey the article horizontally. That is, each belt conveyor 10 is formed near the first shaft 30 and the second shaft 40 at the conveyance end.
In addition, since each belt conveyor 10 in this Embodiment is substantially the same, one belt conveyor is demonstrated as a representative.
As shown in FIGS. 1 and 2, the belt conveyor 10 has a support plate 14 extending horizontally from the main body frame 12, and a first shaft 30 is disposed on the upstream side in the transport direction of the support plate 14. A second shaft 40 is disposed on the downstream side.
A suction hole 15 is formed at the center of the support plate 14. The hole 15 is connected to a negative pressure means (not shown) and communicates with a suction hole 52 formed in the belt 50, and is formed in order to prevent misalignment of articles on the belt 50 during conveyance.
The first shaft 30 includes a roller 32 around which the belt 50 is wound, and a support shaft 34 that rotatably supports the roller 32.
As one end portion 30a of the first shaft 30, a support shaft 34 that extends from the roller 32 toward the main body frame 12 is a pair of upper and lower flat guide plates that project from a part of the support plate 14 in parallel to the upstream side in the transport direction. By being arranged between 24, it is supported in a state where movement in the vertical direction is restricted.
Further, a slide member 38, which will be described later, mounted on the support shaft 34 is conveyed from a part of the support plate 14 at the other end 30b of the first shaft 30 on the side opposite to the one end 30a with the roller 32 interposed therebetween. By being arranged between a pair of upper and lower flat plate-like second guide plates 26 (supports) projecting parallel to the upstream side in the direction, the movement in the vertical direction is restricted.
The support shaft 34 is horizontally supported by the guide plates 24 and 26, the one end 30a of the first shaft 30 is provided with meandering adjusting means, and the other end 30b of the first shaft 30 is provided with a belt. Desorption means is equipped.

支持板１４には、ベルト５０が走行する領域より本体フレーム１２側に寄った箇所に軸孔２０と該軸孔２０と直交する切欠き溝２２が形成されている。
軸孔２０は、一対の案内板２４の間で、第１シャフト３０の一端部３０ａ側における支持シャフト３４に対向する支持板１４の対向面（不図示）から搬送方向（第２シャフト４０と直交する方向）に支持板１４内に形成され、支持板１４を上下方向に貫通形成された切欠き溝２２に支持板１４内で連通している。
切欠き溝２２には操作部材６８が嵌込まれ、その状態で軸孔２０内部には、ねじ棒６４が操作部材６８と螺合するよう嵌入されている。
操作部材６８は、ねじ孔６９を有す円筒形状であり、切欠き溝２２に対し搬送方向にガタツキがなく、作業者などによる上方からの外部操作により回動し得る大きさである。
そして、切欠き溝２２内で操作部材６８が回動すると、ねじ棒６４が搬送方向にのみ移動するよう構成されている。
ねじ棒６４は、先端部６４ａ、中間部６４ｂ、後端部６４ｃからなり、最も大径の中間部６４ｂの外周には雄ねじ６７が切られている。
先端部６４ａは、軸孔２０から第１シャフト３０の一端部３０ａに突出しており、漸次先細りに形成されたテーパー面６５より先端側に小径の小径軸部６６を有している。
そして、先端部６４ａのテーパー面６５及び小径軸部６６は、支持シャフト３４に形成された凹部３５内に受入れられる。
支持シャフト３４の凹部３５には、孔部３６と該孔部３６の一端側から径方向に広がったテーパー面３７が支持シャフト３４を貫通するよう形成されている。
凹部３５のテーパー面３７は、ねじ棒６４の小径軸部６６を孔部３６に案内してテーパー面６５と当接するよう形成されていると共に、ねじ棒６４のテーパー面６５に当接した状態で、ねじ棒６４に対し支持シャフト３４が大きく傾動し得るよう、ねじ棒６４のテーパー面６５の斜面より緩やかに形成されている。
なお、図３（Ａ）のごとく、ベルト５０が走行可能に巻き掛けられた状態では支持シャフト３４がベルト５０によって搬送方向下流側に押圧されるため、図３（Ｂ）のように支持シャフト３４が大きく傾動しても、ねじ棒６４のテーパー面６５と支持シャフト３４のテーパー面３７との当接は維持される。 The support plate 14 is formed with a shaft hole 20 and a notch groove 22 orthogonal to the shaft hole 20 at a position closer to the main body frame 12 side than a region where the belt 50 travels.
The shaft hole 20 is disposed between the pair of guide plates 24 from the facing surface (not shown) of the support plate 14 facing the support shaft 34 on the one end portion 30a side of the first shaft 30 (in the direction perpendicular to the second shaft 40). In the support plate 14, and communicates in the support plate 14 with a notch groove 22 formed through the support plate 14 in the vertical direction.
An operation member 68 is fitted into the notch groove 22, and in this state, a screw rod 64 is fitted into the shaft hole 20 so as to be screwed with the operation member 68.
The operation member 68 has a cylindrical shape having a screw hole 69, has no backlash in the conveying direction with respect to the notch groove 22, and has a size that can be rotated by an external operation from above by an operator or the like.
When the operation member 68 rotates in the notch groove 22, the screw rod 64 is configured to move only in the transport direction.
The screw rod 64 includes a front end portion 64a, an intermediate portion 64b, and a rear end portion 64c, and a male screw 67 is cut on the outer periphery of the largest diameter intermediate portion 64b.
The distal end portion 64a protrudes from the shaft hole 20 to the one end portion 30a of the first shaft 30, and has a small-diameter shaft portion 66 having a smaller diameter on the distal end side than the tapered surface 65 that is gradually tapered.
The tapered surface 65 and the small-diameter shaft portion 66 of the tip end portion 64 a are received in the concave portion 35 formed in the support shaft 34.
The concave portion 35 of the support shaft 34 is formed with a hole 36 and a tapered surface 37 extending in the radial direction from one end side of the hole 36 so as to penetrate the support shaft 34.
The tapered surface 37 of the concave portion 35 is formed so as to guide the small diameter shaft portion 66 of the screw rod 64 to the hole portion 36 so as to contact the tapered surface 65 and in contact with the tapered surface 65 of the screw rod 64. The support shaft 34 is formed more gently than the inclined surface of the tapered surface 65 of the screw rod 64 so that the support shaft 34 can be tilted greatly with respect to the screw rod 64.
As shown in FIG. 3A, in the state where the belt 50 is wound so as to be able to travel, the support shaft 34 is pressed to the downstream side in the transport direction by the belt 50. Therefore, as shown in FIG. Even if the tilt is greatly tilted, the contact between the tapered surface 65 of the screw rod 64 and the tapered surface 37 of the support shaft 34 is maintained.

第１シャフト３０の他端部３０ｂには、図１、２、４のごとくスライド部材３８が支持シャフト３４に回動可能に装着されている。
スライド部材３８は、上下一対の第２の案内板２６間のガイド溝２７内を搬送方向に摺接しながら移動可能とされ、ガイド溝２７の内面に摺接する面が上下共に水平とされ、それらの先端に係合部としての凸曲面３９を有する。
凸曲面３９は、スライド部材３８を一対の第２の案内板２６間のガイド溝２７に嵌挿し易くすると共に、後述するカム部材７８と係合するよう形成されている。
ガイド溝２７より搬送方向下流側における支持板１４には、第２操作部材７２が支軸７６を中心に回動可能に軸支されている。
第２操作部材７２は、図４（Ａ）（Ｂ）のごとく、略半円板状に形成されたカム部材７８と該カム部７８から搬送方向下流側で延出した棒状の把持部７４を有している。
支軸７６を介して把持部７４の対向位置におけるカム部材７８の外周には、図４（Ａ）のごとく、スライド部材３８の凸曲面３９と係合するように、支軸７６側に窪んだ凹曲面７９が形成されている。
なお、カム部材７８の外周をなす半円の中心は、支軸７６より搬送方向上流側に置かれているため、図４（Ｂ）のごとく、把持部７４を下方に回動させる係合解除操作により、カム部材７８が支軸７６を中心に回動させると、凸曲面３９と凹曲面７９との係合状態が解除され、その後、凸曲面３９からカム部材７８の外周迄の距離が序々に遠くなる。 A slide member 38 is rotatably mounted on the support shaft 34 at the other end 30b of the first shaft 30 as shown in FIGS.
The slide member 38 is movable while sliding in the conveying direction in the guide groove 27 between the pair of upper and lower second guide plates 26, and the surface slidably contacting the inner surface of the guide groove 27 is both horizontal and horizontal. The tip has a convex curved surface 39 as an engaging portion.
The convex curved surface 39 is formed so that the slide member 38 can be easily fitted into the guide groove 27 between the pair of second guide plates 26 and is engaged with a cam member 78 described later.
A second operating member 72 is pivotally supported on the support plate 14 on the downstream side in the transport direction from the guide groove 27 so as to be rotatable about a support shaft 76.
As shown in FIGS. 4A and 4B, the second operating member 72 includes a cam member 78 formed in a substantially semi-disc shape and a rod-shaped gripping portion 74 extending from the cam portion 78 on the downstream side in the transport direction. Have.
As shown in FIG. 4A, the outer periphery of the cam member 78 at the position facing the grip portion 74 via the support shaft 76 is recessed toward the support shaft 76 so as to engage with the convex curved surface 39 of the slide member 38. A concave curved surface 79 is formed.
Since the center of the semicircle forming the outer periphery of the cam member 78 is located on the upstream side in the transport direction from the support shaft 76, as shown in FIG. 4B, the engagement is released to rotate the gripping portion 74 downward. When the cam member 78 is rotated about the support shaft 76 by the operation, the engagement state between the convex curved surface 39 and the concave curved surface 79 is released, and thereafter the distance from the convex curved surface 39 to the outer periphery of the cam member 78 gradually increases. It will be far away.

第２操作部材７２は、そのカム部材７８とスライド部材３８が係合する状態においては、ベルト５０に張力がかかった状態で第１シャフト３０の他端部３０ｂを支持する。
一方、第２操作部材７２を回転させて、カム部材７８とスライド部材３８の係合を解除すると第１シャフト３０に装着されたスライド部材３８がベルト５０の張力によって第２の案内板２６、２６の間を搬送方向下流側に移動する。これにより、ベルト５０が弛んで第１シャフト３０の一端部３０ａにおける凹部３５のテーパー面３７がねじ棒６４のテーパー面６５に当接する箇所を支点として、第１シャフト３０の他端部３０ｂが搬送方向に移動して第１シャフト３０が傾動する。このため、ベルト５０を弛めた状態で作業者にとって手前側になる第１シャフト３０の他端部３０ｂ側（回転体の他端部側）に簡易に引き出すことが可能となる。 In a state where the cam member 78 and the slide member 38 are engaged, the second operation member 72 supports the other end portion 30b of the first shaft 30 with the belt 50 being under tension.
On the other hand, when the engagement of the cam member 78 and the slide member 38 is released by rotating the second operation member 72, the slide member 38 attached to the first shaft 30 is moved to the second guide plates 26, 26 by the tension of the belt 50. To the downstream side in the transport direction. Accordingly, the other end portion 30b of the first shaft 30 is conveyed with the belt 50 being loosened and the portion where the tapered surface 37 of the concave portion 35 in the one end portion 30a of the first shaft 30 contacts the tapered surface 65 of the screw rod 64 as a fulcrum. The first shaft 30 is tilted by moving in the direction. For this reason, it is possible to easily pull the belt 50 to the other end portion 30b side (the other end portion side of the rotating body) of the first shaft 30 on the near side with respect to the operator with the belt 50 loosened.

以上のように、ベルトコンベヤ１０には、第２操作部材７２によりスライド部材３８（係合部）の凸曲面３９（係合部）との係合解除操作により、スライド部材３８を搬送方向に移動させ第１シャフト３０（回転体）をその一端部３０ａを支点に傾動させることで、ベルト５０を弛めて第１シャフト３０の他端部３０ｂ側に簡易に引き出し可能にするベルト脱着手段が装備されている。
更に、ベルトコンベヤ１０は、ねじ棒６４に螺合した操作部材６８が外部から回動操作されると、ねじ棒６４が搬送方向に移動し、第１シャフト３０（回転体）の他端部３０ｂにおける凸曲面３９が第２操作部材７２の凹曲面７９に係合する箇所を支点として、第１シャフト３０を搬送方向に傾動させベルト５０の蛇行を修正可能にする。
即ち、ベルトコンベヤ１０には、このようにベルトの蛇行を修正可能にする蛇行調節手段が装備されている。 As described above, in the belt conveyor 10, the slide member 38 is moved in the transport direction by the disengagement operation of the slide member 38 (engagement portion) with the convex curved surface 39 (engagement portion) by the second operation member 72. The first shaft 30 (rotating body) is tilted with its one end 30a as a fulcrum so that the belt 50 can be loosened so that it can be easily pulled out to the other end 30b of the first shaft 30. Has been.
Further, in the belt conveyor 10, when the operation member 68 screwed to the screw rod 64 is rotated from the outside, the screw rod 64 moves in the transport direction, and the other end 30b of the first shaft 30 (rotating body). The first shaft 30 is tilted in the conveying direction by using the portion where the convex curved surface 39 is engaged with the concave curved surface 79 of the second operation member 72 as a fulcrum, so that the meandering of the belt 50 can be corrected.
In other words, the belt conveyor 10 is provided with meandering adjusting means for correcting the meandering of the belt in this way.

以上のことから蛇行調節手段、ベルト脱着手段は共に一個の第１シャフト３０側に集約して構成されている。例えば、ベルト５０の蛇行を修正しても、ベルト脱着手段における第２操作部材７２とスライド部材３８の凸曲面３９（係合部）との係合状態が維持でき、また、蛇行調節手段は、第２操作部材７２による係合が解除される前と再び係合された後で蛇行修正状態を維持することができる。そのため、ベルト脱着手段及び蛇行調節手段を簡素に構成したベルトコンベヤ１０とすることができる。 From the above, the meander adjusting means and the belt attaching / detaching means are both configured to be integrated on one first shaft 30 side. For example, even if the meandering of the belt 50 is corrected, the engagement state between the second operating member 72 and the convex curved surface 39 (engagement portion) of the slide member 38 in the belt detaching means can be maintained. The meandering correction state can be maintained before the engagement by the second operating member 72 is released and after the second operation member 72 is engaged again. Therefore, the belt conveyor 10 in which the belt attaching / detaching means and the meandering adjusting means are simply configured can be obtained.

また、ローラ３２を回転可能に支持する支持シャフト３４は、回転することなく一端部３０ａの凹部３５でねじ棒６４と係合するため、凹部３５におけるねじ棒６４との磨耗を抑制することができる。 Further, since the support shaft 34 that rotatably supports the roller 32 is engaged with the screw rod 64 in the recess 35 of the one end 30a without rotating, it is possible to suppress wear of the screw rod 64 in the recess 35. .

また、蛇行調節手段と、ベルト脱着手段を具備するベルトコンベヤ１０を直列に隣接して配設することで、夫々のベルト５０を他端部３０ｂ側に引き出す際には、第１シャフト３０をその一端部３０ａを支点にベルト５０が弛むよう傾動させるため、隣接したベルトコンベヤを移動させることなくベルト５０を引き出すことができる。
また、蛇行調節手段における操作部材６８を、例えばコンベヤ１０の上方から操作可能な箇所に露出するよう設けることで、作業者がベルトコンベヤ１０に対して、第１シャフト３０の一端部３０ａ側から近づけないようベルトコンベヤ１０が複数、直列に隣接して配設された作業環境や、本体フレーム１２や本体フレーム１２等に配設される不図示のモータなどによって一端部３０ｂ側から作業者が操作し難い、或は、操作できない場合においては、特に簡易にベルト５０の蛇行を修正できる。 Further, by arranging the meandering adjusting means and the belt conveyor 10 having the belt attaching / detaching means adjacent to each other in series, when the respective belts 50 are pulled out to the other end portion 30b side, the first shaft 30 is moved to that side. Since the belt 50 is tilted with the one end 30a as a fulcrum, the belt 50 can be pulled out without moving the adjacent belt conveyor.
Further, by providing the operation member 68 in the meander adjustment means so as to be exposed at a place where the operation can be performed from above the conveyor 10, for example, the operator approaches the belt conveyor 10 from the one end 30 a side of the first shaft 30. An operator operates from the one end 30b side by a working environment in which a plurality of belt conveyors 10 are arranged adjacent to each other in series, a motor (not shown) arranged in the main body frame 12, the main body frame 12, or the like. When it is difficult or cannot be operated, the meandering of the belt 50 can be corrected particularly easily.

また、ベルト５０の張力は、第１シャフト３０の他端部３０ｂが搬送方向へ移動することで開放される。ここで、第１シャフト３０の他端部３０ｂは、第２の案内板２６（支持体）によって搬送方向へのみ移動が許容されている構成とすることで、例えば、第２操作部材７２による係合部３８、３９との係合を解除した際に第１シャフト３０の他端部３０ｂは搬送方向へのみ移動するため搬送端部間でベルト５０を大きく弛めることができる。よってベルト５０が引き出し易くなる。
また、第１シャフト３０の一端部３０ａにおいては、凹部３５がねじ棒６４のテーパー面６５に当接と共に、ねじ棒６４の小径端部６６を受け入れているため、第２操作部材７２による係合解除によりベルト５０が引き出された後に、第１シャフト３０を取り外すことができる。よって、第１シャフト３０の交換や清掃、点検などの作業性を向上させることができる。 The tension of the belt 50 is released when the other end 30b of the first shaft 30 moves in the transport direction. Here, the other end portion 30b of the first shaft 30 is configured to be allowed to move only in the transport direction by the second guide plate 26 (support), for example, the engagement by the second operation member 72. When the engagement with the joint portions 38 and 39 is released, the other end portion 30b of the first shaft 30 moves only in the transport direction, so that the belt 50 can be greatly loosened between the transport end portions. Therefore, the belt 50 can be easily pulled out.
Further, in the one end portion 30 a of the first shaft 30, the recess 35 is in contact with the tapered surface 65 of the screw rod 64 and receives the small diameter end portion 66 of the screw rod 64. After the belt 50 is pulled out by the release, the first shaft 30 can be removed. Therefore, workability such as replacement, cleaning, and inspection of the first shaft 30 can be improved.

次に、第２の実施形態におけるベルトコンベヤ１１０を図５に基づき説明する。
なお、第２の実施形態では、蛇行調整手段における第１シャフト１３０とねじ棒１６４の構成が第１の実施形態とは一部相違しており、該相違する箇所については、符号を新たに付して説明する。
第１シャフト１３０は、ベルト５０が巻き掛けられるローラ１３２が支持シャフトと共に一体回転するよう構成されており、第１シャフト１３０の一端部１３０ａ側における支持シャフトが凸部１３３として球面状に形成されている。
なお、支持シャフトの他端部３０ｂ側におけるベルト脱着手段については、第１の実施形態と同じである。
ねじ棒１６４は、支持ブロック１６４ｂを有している。
支持ブロック１６４ｂは、外側に球面状に凹み形成された凹部１６４ｅと搬送方向に貫通した孔部１６４ｄを有しており、該孔部１６４ｄは先端部１６４ａを回転可能に支持している。
先端部１６４ａには、Ｃリング等からなる抜止め１６４ｃが取着されることにより、先端部１６４ａに対して支持ブロック１６４ｂの搬送方向への移動が規制されている。
支持ブロック１６４ｂは、上下一対の案内板２４の間に配設され、両案内板２４によって上下方向の移動が規制され、操作部材６８が回動操作された際には搬送方向にのみ移動し得るよう支持されている。
支持ブロック１６４ｂの凹部１６４ｅは、図５（Ｂ）のごとく第１シャフト１３０が大きく傾動し得るよう凸部１３３を受け入れて、第１シャフト１３０を回転可能に支持している。 Next, the belt conveyor 110 in 2nd Embodiment is demonstrated based on FIG.
In the second embodiment, the configurations of the first shaft 130 and the screw rod 164 in the meander adjustment means are partly different from those in the first embodiment, and the different parts are newly added with reference numerals. To explain.
The first shaft 130 is configured such that the roller 132 around which the belt 50 is wound rotates together with the support shaft, and the support shaft on the one end portion 130 a side of the first shaft 130 is formed in a spherical shape as the convex portion 133. Yes.
The belt attaching / detaching means on the other end 30b side of the support shaft is the same as in the first embodiment.
The screw rod 164 has a support block 164b.
The support block 164b has a concave portion 164e formed in a spherical shape on the outside and a hole portion 164d penetrating in the transport direction, and the hole portion 164d rotatably supports the tip end portion 164a.
A stopper 164c made of a C ring or the like is attached to the distal end portion 164a, thereby restricting movement of the support block 164b in the transport direction relative to the distal end portion 164a.
The support block 164b is disposed between the pair of upper and lower guide plates 24, the movement in the vertical direction is restricted by the both guide plates 24, and can move only in the transport direction when the operation member 68 is rotated. It is supported as such.
The concave portion 164e of the support block 164b receives the convex portion 133 so that the first shaft 130 can be largely tilted as shown in FIG. 5B, and rotatably supports the first shaft 130.

以上のように、ベルトコンベヤ１１０における、蛇行調節手段は、第１シャフト１３０の一端部１３０ａに係合し搬送方向に移動可能に配設されたねじ棒１６４と、外部から操作可能な箇所に露出し、ねじ棒１６４に螺合した操作部材６８とを有している。図５（Ｂ）のごとくこの操作部材６８の回動に伴いねじ棒１６４が搬送方向に移動することで、第１シャフト１３０をその他端部３０ｂを支点に搬送方向に傾動させベルト５０の蛇行を簡易に修正可能に構成されている。また、第２操作部材７２による係合部３８，３９との係合解除操作によりベルト５０を弛めて第１シャフト１３０の他端部３０ｂ側にベルト５０を引き出すベルト脱着手段においては、第１シャフト１３０の一端側１３０ａにおける凸部１３３が凹部１６４ｅに当接する箇所を支点として第１シャフト１３０の他端部３０ｂが搬送方向に移動して第１シャフト１３０が傾動するよう構成されている。これら蛇行調節手段、ベルト脱着手段は共に一個の第１シャフト１３０側に集約され第１シャフト１３０を傾動させるよう構成されている。これにより、ベルト脱着手段及び蛇行調節手段を簡素に構成したベルトコンベヤ１１０とすることができる。 As described above, the meandering adjusting means in the belt conveyor 110 is exposed to the screw rod 164 that is arranged to be engaged with the one end portion 130a of the first shaft 130 and to be movable in the conveying direction, and to be operable from the outside. And an operation member 68 screwed onto the screw rod 164. As shown in FIG. 5B, the screw rod 164 moves in the transport direction along with the rotation of the operation member 68, so that the first shaft 130 is tilted in the transport direction with the other end 30b as a fulcrum to meander the belt 50. It can be easily modified. Further, in the belt attaching / detaching means, the belt 50 is loosened by the disengagement operation with the engaging portions 38 and 39 by the second operating member 72 and the belt 50 is pulled out to the other end portion 30b side of the first shaft 130. The other end portion 30b of the first shaft 130 is moved in the transport direction so that the first shaft 130 tilts with a place where the convex portion 133 on the one end side 130a of the shaft 130 contacts the concave portion 164e as a fulcrum. Both of the meandering adjusting means and the belt attaching / detaching means are integrated on one first shaft 130 side and configured to tilt the first shaft 130. Thereby, it can be set as the belt conveyor 110 which comprised simply the belt removal | desorption means and the meandering adjustment means.

次に、第３の実施形態におけるベルトコンベヤ２１０を図６、図７に基づき説明する。
ベルトコンベヤ２１０は、２つのローラ３２を回転可能に支持する支持シャフト２３４を有した第１シャフト２３０によってベルト５０が走行可能に巻き掛けられている。
なお、第３の実施形態においては、第１の実施形態よりベルト５０、支持板１４が幅広とされていることから、第１シャフト２３０の支持シャフト２３４を補強フレーム２３３で補強すると共に、支持シャフト２３４と共に蛇行調節手段における第１シャフト２３０の一端部２３０ａを補強フレーム２３３で構成している。
また、第３の実施形態では、水平方向に回動する第２操作部材２７２によってベルト脱着手段を構成している。これらの点が第１の実施形態とは相違しており、これらの相違する箇所について、符号を新たに付して以下、説明する。 Next, the belt conveyor 210 in 3rd Embodiment is demonstrated based on FIG. 6, FIG.
The belt conveyor 210 has a belt 50 wound around a first shaft 230 having a support shaft 234 that rotatably supports two rollers 32.
In the third embodiment, since the belt 50 and the support plate 14 are wider than those in the first embodiment, the support shaft 234 of the first shaft 230 is reinforced by the reinforcing frame 233 and the support shaft is also provided. 234 and one end 230a of the first shaft 230 in the meandering adjusting means are configured by a reinforcing frame 233.
In the third embodiment, the belt attaching / detaching means is configured by the second operating member 272 that rotates in the horizontal direction. These points are different from those of the first embodiment, and these different parts will be described below with new reference numerals.

補強フレーム２３３は、第１シャフト２３０の一端部２３０ａとして支持シャフト２３４を回転可能に支持すると共に２つのローラ３２の間で支持シャフト２３４を回転可能に支持している。第１シャフト２３０の一端部２３０ａは、上下一対の平板状の案内板２４の間に配設され、両案内板２４によって上下方向の移動が規制され、搬送方向にのみ移動し得るよう支持されている。
補強フレーム２３３における案内板２４の間に位置する部位には、ねじ棒６４における先端部６４ａのテーパー面６５及び小径軸部６６が受け入れられる凹部２３５が形成されている。凹部２３５は、支持シャフト３４に直交する方向に形成された孔部２３６と、該孔部２３６の開口端から径方向に広がった方向に形成されるテーパー面２３７を有している。
このことにより、第１の実施形態の凹部３５とねじ棒６４との係合と同様の係合状態が補強フレーム２３３の凹部２３５とねじ棒６４との間で生じる。 The reinforcing frame 233 supports the support shaft 234 rotatably as one end portion 230a of the first shaft 230 and supports the support shaft 234 rotatably between the two rollers 32. One end portion 230a of the first shaft 230 is disposed between a pair of upper and lower flat plate-like guide plates 24, and the movement in the vertical direction is restricted by both guide plates 24, and is supported so as to move only in the transport direction. Yes.
A portion of the reinforcing frame 233 positioned between the guide plates 24 is formed with a concave portion 235 for receiving the tapered surface 65 of the tip end portion 64a and the small diameter shaft portion 66 of the screw rod 64. The recess 235 has a hole 236 formed in a direction orthogonal to the support shaft 34 and a tapered surface 237 formed in a direction extending radially from the opening end of the hole 236.
As a result, an engagement state similar to the engagement between the concave portion 35 and the screw rod 64 in the first embodiment occurs between the concave portion 235 of the reinforcing frame 233 and the screw rod 64.

第１シャフト２３０の他端部２３０ｂとしてスライド部材２３８が、図６（Ａ）（Ｂ）のごとく支持シャフト２３４に回動可能に装着されると共に補強フレーム２３３に連結され、上下一対の平板状の第２の案内板２６（支持体）の間に配設されることで、上下方向の移動が規制された状態で支持されている。
スライド部材２３８は、上下一対の第２の案内板２６間のガイド溝２７内を搬送方向に摺接しながら移動可能とされ、ガイド溝２７の内面に摺接する面が上下共に水平とされ、それらの先端に係合部としての凸曲面２３９を有する。 As shown in FIGS. 6A and 6B, a slide member 238 is rotatably mounted on the support shaft 234 and connected to the reinforcing frame 233 as the other end portion 230b of the first shaft 230. By being disposed between the second guide plates 26 (supports), it is supported in a state where movement in the vertical direction is restricted.
The slide member 238 is movable while sliding in the conveying direction in the guide groove 27 between the pair of upper and lower second guide plates 26, and the surface slidingly contacting the inner surface of the guide groove 27 is horizontal in both directions. It has a convex curved surface 239 as an engaging portion at the tip.

ガイド溝２７内において、支持板１４には第２操作部材２７２が配設されている。
第２操作部材２７２は、図７（Ａ）（Ｂ）のごとく、略矩形状に形成されたカム部材２７８と該カム部２７８から搬送方向上流側に延出した棒状の把持部２７４を有しており、支軸２７６を中心に水平方向に回動可能に軸支されている。
カム部材７８の外周には、図７（Ｂ）のごとく、スライド部材２３８の凸曲面２３９と係合するように、支軸２７６側に窪んだ凹曲面２７９が形成されており、把持部７４を搬送方向下流側に水平回動させる係合解除操作により、カム部材２７８が支軸２７６を中心に回動すると、凸曲面２３９と凹曲面２７９との係合状態が解除される。 A second operating member 272 is disposed on the support plate 14 in the guide groove 27.
As shown in FIGS. 7A and 7B, the second operating member 272 has a cam member 278 formed in a substantially rectangular shape and a rod-shaped gripping portion 274 extending from the cam portion 278 to the upstream side in the transport direction. It is pivotally supported so as to be pivotable in the horizontal direction around a spindle 276.
As shown in FIG. 7B, a concave curved surface 279 that is recessed toward the support shaft 276 is formed on the outer periphery of the cam member 78 so as to engage with the convex curved surface 239 of the slide member 238. When the cam member 278 is rotated about the support shaft 276 by the engagement release operation for horizontally rotating in the transport direction downstream side, the engaged state between the convex curved surface 239 and the concave curved surface 279 is released.

第２操作部材２７２は、そのカム部材２７８とスライド部材２３８が係合する状態においては、ベルト５０に張力が、かかった状態で第１シャフト２３０の他端部２３０ｂを支持する。即ち、操作部材６８の回動に伴ったねじ棒６４の搬送方向への移動により、ベルト５０の蛇行を修正する蛇行調節手段においては、第１シャフト２３０における凸曲面２３９が凹曲面２７９に当接する箇所を支点として、第１シャフト２３０の一端部２３０ａが搬送方向に移動して、第１シャフト２３０が傾動するよう構成されている。
また、第２操作部材２７２による係合部２３９との係合解除操作により、ベルト５０を弛めて第１シャフト２３０の他端部２３０ｂ側にベルト５０を引き出すベルト脱着手段においては、第１シャフト２３０の一端部２３０ａにおける凹部２３５がねじ棒６４のテーパー面６５に当接する箇所を支点として、第１シャフト２３０の他端部２３０ｂが搬送方向に移動して、第１シャフト２３０が傾動するよう構成されている。 In a state where the cam member 278 and the slide member 238 are engaged, the second operation member 272 supports the other end portion 230b of the first shaft 230 in a state where tension is applied to the belt 50. That is, in the meandering adjusting means for correcting the meandering of the belt 50 by the movement of the screw rod 64 in the conveying direction accompanying the rotation of the operation member 68, the convex curved surface 239 of the first shaft 230 abuts on the concave curved surface 279. With the location as a fulcrum, the one end 230a of the first shaft 230 moves in the transport direction, and the first shaft 230 tilts.
Further, in the belt attaching / detaching means for pulling out the belt 50 to the other end 230b side of the first shaft 230 by releasing the engagement with the engaging portion 239 by the second operating member 272, the first shaft The first shaft 230 is tilted by moving the other end portion 230b of the first shaft 230 in the conveying direction with a position where the concave portion 235 of the one end portion 230a of the 230 abuts against the tapered surface 65 of the screw rod 64 as a fulcrum. Has been.

これら蛇行調節手段、ベルト脱着手段は共に一個の第１シャフト２３０側に集約され該第１シャフト２３０を傾動させるよう構成されており、例えば、ベルト５０の蛇行を修正しても、ベルト脱着手段における第２操作部材２７２の凹曲面２７９とスライド部材２３８の凸曲面２３９との係合状態が維持でき、また、蛇行調節手段は、第２操作部材２７２による係合が解除される前と再び係合された後で蛇行修正状態を維持することができる。そのため、ベルト脱着手段及び蛇行調節手段を簡素に構成したベルトコンベヤ２１０とすることができる。
また、第１シャフト２３０の支持シャフト２３４を補強フレーム２３３で補強することで、ベルト５０の蛇行修正に伴いねじ棒６４が搬送方向に移動する際に、ねじ棒６４によって支持シャフト２３４の一端部２３０ａが押圧されること等で、支持シャフト２３４の変形を防ぎ、ベルト５０の蛇行を適切に修正することができる。
また、支持シャフト２３４の変形を防ぐことによって、係合部としてのスライド部材２３８の凸曲面２３９と第２操作部材２７２の凹曲面２７９との係合状態を良好に維持することができる。 These meandering adjusting means and belt attaching / detaching means are both concentrated on one first shaft 230 side and configured to tilt the first shaft 230. For example, even if the meandering of the belt 50 is corrected, the belt attaching / detaching means The engaged state of the concave curved surface 279 of the second operating member 272 and the convex curved surface 239 of the slide member 238 can be maintained, and the meander adjusting means is engaged again before the engagement by the second operating member 272 is released. The meandering correction state can be maintained. Therefore, the belt conveyor 210 can be configured by simply configuring the belt attaching / detaching means and the meandering adjusting means.
Further, by reinforcing the support shaft 234 of the first shaft 230 with the reinforcement frame 233, when the screw rod 64 moves in the transport direction in accordance with the meandering correction of the belt 50, the one end portion 230a of the support shaft 234 is moved by the screw rod 64. By being pressed, etc., deformation of the support shaft 234 can be prevented, and the meandering of the belt 50 can be corrected appropriately.
In addition, by preventing the support shaft 234 from being deformed, the engagement state between the convex curved surface 239 of the slide member 238 as the engaging portion and the concave curved surface 279 of the second operation member 272 can be maintained well.
