When assembling the conveyor equipment 1, the conveyor frame 10 integrally formed by extrusion molding of aluminum can easily form the upper dovetail groove portion 11, the lower dovetail groove portion 15, and the like, and uses the upper dovetail groove portion 11 and the lower dovetail groove portion 15. Thus, the fixing (coupling) to the frame-shaped main body 3 and the fixing (coupling) such as the side guide body 65 and the cover body 66 can be easily and reliably performed without interposing an intermediate member such as a bracket.
[0030]
The machining of the conveyor frame 10 requires only the straight through holes 16 into which the bearings 21 can be fitted and the straight through holes 17 and 18 into which the bolts, nuts 44, 46, and 52 can be inserted. It can be done quickly and cost can be reduced. Further, the bearing 21 fitted in the through hole 16 can be stably positioned on the conveyor frame 10 side by a retaining ring 22 that is inexpensive and easy to operate.
[0031]
When the assembled conveyor facility 1 is operated, the endless rotating body 55 can be rotated by forcibly rotating the driving wheel body 50 by the driving unit 48 in the rotation driving means 40. At this time, since the endless rotating body 55 is pushed down by the tension guide wheel body 43 group in the action path portion that is in contact with the passive wheel body 41 group from above, a sufficient contact with the passive wheel body 41 group is achieved. It can contact by contact force. Accordingly, the transport body 30 group can be driven and rotated by the endless rotating body 55, and thus the plate-like body 69 supported by the transport ring body 32 group can be transported on the transport path 35. At that time, the bolts and nuts 46 are loosened, the lift adjustment tool 51 is operated to raise and lower the drive unit frame 45 and the like, and then the bolts and nuts 46 are fastened to change the vertical position of the driving wheel body 50. Thus, the tension of the endless rotating body 55 can be adjusted.
[0032]
The conveyance of the plate-like body 69 as described above is performed by supporting the plate-like body 69 by the group of conveyance wheels 32 provided at a plurality of locations in the length direction of the shaft 31, thereby reducing the contact surface (friction resistance). Then, it can be performed without damaging the surface of the plate-like body 69.
[0033]
In the transport mode of the plate-like body 69 as described above, the plate-like body 69 is not transported linearly along the transport path 35, but is transported obliquely (meandering) with respect to the transport path 35 and side guide bodies 65. When it comes into contact with the position, adjustment is performed by operating the position adjusting means 60.
[0034]
That is, for example, when the plate-like body 69 is conveyed obliquely toward the left side (one end side), the bolts and nuts 20 corresponding to the left conveyor frame 10 are loosened, and then the position adjustment tool 62 is operated to operate the left side. The conveyor frame 10 is pushed and moved to the lower side. Thereby, the conveyance body 30 group is inclined so that one end side of the shaft 31 is the lower side, and the bolts and nuts 20 are fastened in this state.
[0035]
For example, when the plate-like body 69 is conveyed obliquely toward the right side (the other end side), the bolts and nuts 20 corresponding to the left conveyor frame 10 are loosened, and then the position adjustment tool 62 is reversely operated. The left conveyor frame 10 is pulled and moved to the upper side (see FIG. 5). Thereby, the conveyance body 30 group is inclined so that one end side of the shaft 31 is the upper side, and the bolts and nuts 20 are fastened in this state.
[0036]
By such an operation, the plate-like body 69 can be adjusted to a state in which the plate-like body 69 can be conveyed linearly along the conveyance path 35. That is, the straightness of the conveyor facility 1 can be adjusted. When a plurality of conveyor facilities 1 are installed and used with the conveyance path 35 being linear, it is preferable to adjust all the tables in order, one by one from the top.
[0037]
In the above-described embodiment, the conveyor frame 10 is formed by extrusion molding of aluminum, but this may be a conveyor frame formed by bending a strip steel plate.
[0039]
In the above-described embodiment, the conveyor frame 10 on one end side of the pair of left and right conveyor frames 10 is configured to be position-adjustable in the length direction via the position adjusting means 60. 10 together via a position adjusting means 60 may be etc. positions adjustably configured format in the length direction.
