The cost of 9, 19 increases. Further, as is apparent from FIG. 10, since the surface on the guide 45 side of the small-sized injection molding machine and the surface on the guide 45 side of the medium-sized injection molding machine are aligned, the surface farther from the guide 45 is Become irregular. The surface far from the guide 45 faces the inspection passage of the worker, and if the surface is not aligned in such a manner, the flow line of the worker will meander, and the worker will easily come into contact with the injection molding machine, and the burden on the worker will increase. That is, in the layout of the conventional injection molding machine, a mold exchange table is always provided, and the surface of the injection molding machine becomes uneven on the side of the inspection passage. Therefore, these improvements are required.

Injection molding machine 45S and medium-sized (M size) injection molding machine 4
5M are arranged in series, and the surfaces of the injection molding machines 45L, 45S, 45M facing the common rails 31.
6S, 46M, the surface farther from the common rail 31... Are called working side surfaces 47L, 47S, 47M, and the injection molding machine 45 is used.
L, 45S, and 45M device lengths were changed to machine lengths L1, L2, and L.
3. The machine width W1, W2, and W3 are machine widths orthogonal to the machine width, and the machine width W of the plurality of injection molding machines 45L, 45S, and 45M.
When W1, W2, and W3 are different from each other, the working side surfaces 47L, 47S, and 47M of the injection molding machine are aligned by being along the straight line L5. This can be achieved by changing the length of the branch rails 32. As a result, the work flow line becomes straight, and the worker is less likely to come into contact with the injection molding machines 45L, 45S, and 45M, and the burden on the worker can be greatly reduced.

5 and 15 are on the shared rails 31 and 31. FIG. 9 is a layout diagram of a main part of a rail according to the present invention. In view of crossing a common rail 31... With a branch rail 32. Notches 49 must be provided. In order to prevent lateral movement of the bogie, it is necessary to use both flanged wheels on one of the left and right wheels (see the right wheel in FIG. 8) or to use one flanged wheels on both the left and right wheels, and pass these flanges. This is because the gaps t and t are needed to make the gap.
The notch 49 is necessary, and it is unavoidable that the mold exchanging cart slightly moves up and down in the notch 49, but it is better that the vertical movement caused by the notch 49 is small. That is for sure.

2 is operated to lower the rail piece 54 to the position of the imaginary line.
Next, the turning cylinder 55 is operated to turn the rail piece 54 together with the cylinder 52 by 90 °. Subsequently, the cylinder 52 is operated to raise the rail piece 54 so as to follow the branch rails 32. Since the gaps t0, t0 at both ends of the rail piece 54 are very small, there is no danger that the mold exchanging truck will move up and down at the intersection, and there is no danger of giving unnecessary vibration to the placed mold.
