The drive shaft 22 is rotationally driven by a drive unit such as a motor (not shown), and the rotational driving force is transmitted to each roller 16 via each transmission belt 26.

また、ドライブシャフト22はドライブシャフトカバー装置31によって覆われている。このドライブシャフトカバー装置31は、ドライブシャフト22を覆うカバー体32とこのカバー体32をフレーム14に支持する複数の支持体33とを有している。   The drive shaft 22 is covered with a drive shaft cover device 31. The drive shaft cover device 31 includes a cover body 32 that covers the drive shaft 22 and a plurality of support bodies 33 that support the cover body 32 on the frame 14.

カバー体32は、例えばゴムや軟質プラスチックなどの可撓性および弾性を有する材料で、複数の網目34を有する網状に形成されたカバー35を備え、このカバー35が複数の支持体33によってドライブシャフト22の下面から両側面にかけて覆うように略Ｕ字形に形状に保持される。カバー35の両側縁部にはカバー35の両側縁部を覆ってドライブシャフト22の軸方向に沿って直線状に形状保持する形状保持体36が取り付けられている。この形状保持体36は、例えばアルミニウムなどの金属や硬質プラスチックなどの剛性を有する材料で、カバー35の側縁部が差し込まれる断面略Ｃ字形に形成されている。これらカバー35と形状保持体36とが、カバー35の網目34に通して形状保持体36の周囲に巻き付けられた結合部材としての複数の結束バンド37によって結合されている。   The cover body 32 is made of a material having flexibility and elasticity, such as rubber or soft plastic, and includes a cover 35 formed in a net shape having a plurality of meshes 34. The cover 35 is driven by a plurality of support bodies 33. It is held in a substantially U shape so as to cover from the lower surface of 22 to both side surfaces. A shape holding body 36 that covers the both side edges of the cover 35 and holds the shape linearly along the axial direction of the drive shaft 22 is attached to both side edges of the cover 35. The shape holding body 36 is made of a material having rigidity such as a metal such as aluminum or a hard plastic, and has a substantially C-shaped cross section into which the side edge of the cover 35 is inserted. The cover 35 and the shape holding body 36 are coupled by a plurality of binding bands 37 as coupling members that are wound around the shape holding body 36 through the mesh 34 of the cover 35.

支持体33は、例えば金属製で、カバー35の下面を支える下面支え部38およびカバー35の両側面を支える側面支え部39を有し、カバー35をドライブシャフト22の下面から両側面にかけて覆うように略Ｕ字形に形状に保持する断面略コ字形に形成されており、一方の側面支え部39には一側の側部フレーム12の下面にボルト止めされる取付部40が形成されている。両側の側面支え部39には結合孔41が形成されており、支持体33とカバー35とが、結合孔41およびカバー35の網目34に通して支持体33に巻き付けられた結合部材としての結束バンド42によって結合されている。   The support 33 is made of, for example, metal, and has a lower surface support portion 38 that supports the lower surface of the cover 35 and a side surface support portion 39 that supports both side surfaces of the cover 35, and covers the cover 35 from the lower surface of the drive shaft 22 to both side surfaces. The side support portion 39 is formed with a mounting portion 40 that is bolted to the lower surface of the side frame 12 on one side. A coupling hole 41 is formed in the side support portions 39 on both sides, and the support 33 and the cover 35 are bound as a coupling member wound around the support 33 through the coupling hole 41 and the mesh 34 of the cover 35. Combined by band 42.

次に、本実施の形態の作用を説明する。   Next, the operation of the present embodiment will be described.

ドライブシャフトカバー装置31をコンベヤ11に設置するには、例えば予めカバー体32を結束バンド42で結合した各支持体33を一側の側部フレーム12にボルト止めするか、または、各支持体33を一側の側部フレーム12にボルト止めし、これら支持体33にカバー体32を載せ、このカバー体32と各支持体33とを結束バンド42で結合する。   In order to install the drive shaft cover device 31 on the conveyor 11, for example, each support body 33 in which the cover body 32 is previously coupled by the binding band 42 is bolted to the side frame 12 on one side, or each support body 33 Is bolted to the side frame 12 on one side, the cover body 32 is placed on the support body 33, and the cover body 32 and each support body 33 are coupled by the binding band.

このとき、図４に示すように、脚体15の一部がカバー35と干渉する干渉物としてあっても、カバー35が脚体15に当接すれば、カバー35が容易に撓み、脚体15との干渉を容易に回避でき、そのため、従来のようにカバーを切り欠いたり切断することなく、ドライブシャフトカバー装置31を容易に設置することができる。   At this time, as shown in FIG. 4, even if a part of the leg 15 is an interference object that interferes with the cover 35, if the cover 35 abuts on the leg 15, the cover 35 is easily bent and the leg 15 Therefore, the drive shaft cover device 31 can be easily installed without cutting or cutting the cover as in the prior art.

そして、コンベヤ11による搬送物の搬送時には、図示しないモータなどの駆動部によってドライブシャフト22を回転駆動し、このドライブシャフト22から各伝達ベルト26を介して各ローラ16に回転駆動力を伝達し、搬送方向の上流側からローラ16上に送り込まれる搬送物を搬送方向の下流側へ搬送する。   And when conveying the conveyed product by the conveyor 11, the drive shaft 22 is rotationally driven by a driving unit such as a motor (not shown), and the rotational driving force is transmitted from the drive shaft 22 to each roller 16 via each transmission belt 26. The conveyed product sent onto the roller 16 from the upstream side in the conveying direction is conveyed downstream in the conveying direction.

このとき、ドライブシャフト22の周囲をカバー35で覆っているため、ドライブシャフト22や伝達ベルト26などへの引っ掛けや巻き込みを防止できる。   At this time, since the periphery of the drive shaft 22 is covered with the cover 35, the drive shaft 22 and the transmission belt 26 can be prevented from being caught or caught.

しかも、形状保持体36でカバー35の両側縁部をドライブシャフト22の軸方向に沿って直線状に形状保持しているため、カバー35の自由端である両側縁部が撓むのを規制し、カバー35でドライブシャフト22を確実に覆うことができ、しかも、形状保持体36でカバー35の縁部を覆い、網状であるカバー35の縁部のぎざぎざした切り口が露出するのを防止できる。   In addition, since the shape holding body 36 holds both side edges of the cover 35 in a straight line shape along the axial direction of the drive shaft 22, the side edges that are the free ends of the cover 35 are prevented from being bent. The drive shaft 22 can be reliably covered with the cover 35, and the edge of the cover 35 can be covered with the shape holding body 36, thereby preventing the jagged cut at the edge of the cover 35 having a net shape from being exposed.

また、カバー35を網状に設けたことにより、カバー35の網目34を通じてドライブシャフト22、プーリ25および伝達ベルト26などの状態を確認でき、カバー35内に塵埃や搬送物の破片を含むごみなどが網目34を通じて落下し、ごみなどが堆積するのを低減できる。   In addition, by providing the cover 35 in a mesh shape, the state of the drive shaft 22, the pulley 25, the transmission belt 26, etc. can be confirmed through the mesh 34 of the cover 35, and dust and other debris that contains debris in the cover 35 are contained in the cover 35. Falling through the mesh 34 and the accumulation of dust and the like can be reduced.

しかも、網状のカバー35の網目34を利用して、結束バンド37で形状保持体36と容易に結合できるとともに、結束バンド42で支持体33と容易に結合できる。なお、結合部材としては、結束バンド37，42に限らず、紐や線材など用いてもよい。   In addition, the mesh 34 of the mesh-like cover 35 can be used to easily couple the shape holder 36 with the binding band 37 and easily couple the support 33 with the binding band 42. In addition, as a coupling member, you may use not only the binding bands 37 and 42 but a string, a wire, etc.

なお、網状のカバー35としては、ゴムや軟質プラスチックの材料に限らず、金属材料でもよく、この場合、網の線が細い金網を用いることによって可撓性を確保することができる。 The net-like cover 35 is not limited to rubber or soft plastic material, but may be a metal material. In this case, flexibility can be ensured by using a metal net with thin net lines .

また、形状保持体36を用いればカバー35の両側縁部が撓むのを確実に規制できるが、形状保持体36を用いなくてもよく、この場合でもカバー35の材質によって両側縁部が撓むのをある程度抑えられる。   In addition, if the shape holding body 36 is used, the side edges of the cover 35 can be reliably restrained from bending, but the shape holding body 36 may not be used. In this case, both side edges may be bent depending on the material of the cover 35. To some extent.
