Abstract

PURPOSE:To move a truck so smoothly, by making a sidewise moving attitude of the truck of a car type conveyor keepable right even on both straight and circular tracks, while coupling the truck an a driving chain together to be invariable in a horizontal position, and simplifying its coupling structure. CONSTITUTION:A truck 15 travels on a flat outer rail 18 and an inner rail 19 on tops of straight tacks 16a and 16b and a semicircular track 17 with flat rollers 20 and 21. A driving chain 22 paralleled with them is installed between these rails 18 and 19, and its attachement 23 is connected to a setting metal device 24 hangingly installed in this truck 15. This connected position should be on a base line 25. At this base line 25 and its front and rear parts, guide rollers 26, 27 and 28 adjoining to an inner surface of the inner rail 19 at these straight tracks 16a and 16b are pivotally supported on a lower surface of the truck 15 while guide rollers 29, 30 and 31 adjoining to an outer surface of the rail 19 at the semicircular track 17 are also pivotally installed, respectively. A guide plate 32 having plane sides 35a and 35b is set up in the outside of the inner rail 19 of the semicircular track 17, and a circular side 34 is formed in this guide plate 32.

れる。5 to 7 show an example of a conventional guiding device, in which the truck 1 runs on parallel inner rails 2 and outer rails 3 by means of rollers 4.5, and the guiding device engages with the inner rails 2 in the front and rear directions. 6.6. The guide device 6 has a metal fitting 8 equipped with two guide rollers 7 that are in contact with both side surfaces of the inner rail 2, and is pivoted on the center line of the inner rail 2 so that the first part of the bogie can freely rotate horizontally. The carriage 1 is transported between the rails 2, 3 in engagement with a drive chain 9 moving parallel thereto.

The axis of symmetry 1 is a pin 11 that is vertically disposed on the carriage 1 on the axis of symmetry 10 of the drive chain 9.
It fits into the long hole 13 in the 0 direction. The reason why the elongated hole 13 is used is that the distance between the line 14 connecting the horizontal rotation center of the guide device 6.6 and the axotiment 12 is different between a straight track and a curved track of the rail. Such engagement between the pin 11 and the elongated hole 13 is good on a curved road because the chain 9 is guided, but on a straight road there is no guide, so the chain 9 is not guided as shown in FIG.
This is undesirable because it bends into a dogleg shape and causes the axotiment 12 to tilt, resulting in the cart not moving smoothly and slipping.
