Next, the operation by operating the operating tool 78, that is, the transport work will be explained.

4 to 6, all the transmission rollers 21 are moved upward together with the spindle 18 by the cylinder device 37, and brought into pressure contact with the corresponding conveyance rollers 18, thereby extending the entire length of the conveyance path 28 into the driving area. The state of use shown in A is shown. The motor 29
Therefore, the chain 24 is constantly driven, and therefore all the sprockets 20 engaged with the chain 24 are rotating around the support shaft 18. Further, since the transmission roller 21 is in contact with the lower outer circumference of the conveying roller 13 , the group of conveying rollers 13 is forcibly rotated, and the object to be conveyed 30 can be conveyed on the conveying path 23 . Furthermore, when the conveyed object 30 is stopped by a stopper device (not shown), the frictional conveying force on the conveying roller 13 side against the conveyed object 30 is greater than the frictional force of the friction transmission section 22. The boss portion of the sprocket 20 rotates in sliding contact with the conveyance roller 13. As a result, although the sprocket 20 is constantly rotating, the rotation of the conveying roller 13 is stopped, and the conveyed object 3 is stopped.
0 is stored without any sliding contact occurring on the lower surface side.

In the above, the entire length of the conveyance path 23 is defined as the drive area A, but this is because the transmission roller 21 is moved downward by the reverse operation of the cylinder device 37, and the transmission roller 13 is moved downward as shown by the imaginary line in FIG. By separating the rollers 21, the conduction from the transmission roller 21 to the conveying roller 13 is cut off, thereby stopping the rotation of the conveying roller 13 group as shown in the non-driving area B in FIG. Thus, the object 30 to be transported can be stored on the transport path 28. At this time, the drive area A detects the transported object 30 using a sensing lever, a phototube device, etc.
Conveyance roller 1 on the front side of conveyance of this conveyed object 30
3 is sequentially forcibly rotated, and the conveyed object 30
By sequentially controlling the rotation of the conveying rollers 13 that have passed through, it is possible to sequentially displace the conveying rollers 13 in the conveying direction. In addition, at a specific location, a non-driving area B can be formed using a control signal, etc., to store the transported object 30, and when a subsequent transported object 30 approaches this transported object 30, an automatic control is performed. As a result, the driving area A is dissolved to become a non-driving area B, and continuous storage can be performed without collision.

When handling a long object 30 as shown in FIG. 8, the set pitch P is lengthened,
The number of transmission unit units 38 including the conveyance roller 13, transmission roller 21, etc. can be reduced. To do this, first remove the cover body 33, then loosen the bolts 10A and 10B, and then
Guided by B, both support frames 9A and 9B are moved to conveyance path 2.
After moving in direction 3, bolts 10A and 10B are moved to nut bodies 3A and 3B that have been moved integrally.
Just tighten and fix it. At that time, the extra rollers 13, support frames 9A, 9B, etc. are removed. Then, a long cover body 33 corresponding to the changed pitch is attached.

Effects of the invention According to the invention with the above configuration, the main body and the cover body can be manufactured into long lengths by extrusion, molding, etc., and can be cut to a desired length for use, depending on the model of the device to which they are attached. can be provided quickly. The main body can be attached to the attached device using any one of the plurality of attachment grooves,
Can be used for each model. In addition, after attaching the cover body to the main body via the upper and lower fitting parts, assembly can be performed by fitting the side covers between these side edges, and the cover body can be removed by the reverse action. I can do it. This allows wiring, repairs, inspections, etc. to be performed easily. Furthermore, wiring and terminal blocks can be stably fixed in desired locations using tapping grooves and dovetail grooves for equipment installation.Furthermore, wiring can be routed from the bottom of the operation box body through the wiring path to the device to be installed. By guiding it to the side, you can make it invisible from the outside.
