Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor device with a trolley movably supported on a guide rail via horizontal axle wheels.

Conventional conveyor devices of this type maintain a constant distance between the trolley and each horizontal axis wheel supported on the side of the trolley so that the wheel transfer trajectory on the same guide rail is one. Ta.

Therefore, the guide rail suffers from severe wear at a portion corresponding to the locus of one wheel transfer, shortening the useful life of the guide rail.

The present invention aims to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the attached illustrative drawings.

1 to 3, reference numeral 1 denotes a drive trolley connected to a drive chain 2, which has a pair of left and right horizontal wheels 3, 4 at both front and rear ends, and a support shaft at the top. 5
It is equipped with a traction tool 6 which is pivotally supported by and is vertically swingable.

Reference numeral 7 denotes a weight portion that biases and holds the traction tool 6 at the upper limit of movement position shown by the solid line in FIG.

Reference numerals 8 and 9 indicate guide rails each having a U-shaped cross section and supporting and guiding the wheels 3 and 4 on the left and right sides respectively, and are supported by support members 1 degree at appropriate intervals.

Reference numeral 11 denotes a driven trolley equipped with a dock 12 that engages with the towing tool 6, and is equipped with a pair of left and right horizontal wheels 13.14 at both front and rear ends, and these wheels 13.14 are attached to the support member 10. The left and right sides are respectively fitted and supported by a pair of supported left and right guide rails 15 and 16 that are U-shaped in cross section.

This driven trolley 11 is connected to the guide rails 15 and 16.
It is connected to a plurality of other trolleys that are supported and guided in the same way to form a conveyance moving body that propels the workpiece support cart, but since this is well known in the art, illustrations and explanations will be omitted.

In the above-mentioned conveyor device, as shown in FIGS. 2 and 3, the distance between the rear wheel 4 and the top 1, which is connected to the drive trolley 1, is determined by the distance between the front wheel 3 and the trolley. 1 (in other words, the distance between the rear wheels 4 is wider than the distance between the front wheels 3), and the guide rails 8 and 9 are connected to the front wheels 3 and the rear wheels. The width is increased so as to be able to support and guide any of 4.

Similarly, the distance between the rear wheel 14 of the driven trolley 11 and the 01J-11 is set wider than the distance between the front wheel 13 and the trolley 11, and the waist guide rails 15, 16 are set wider than the distance between the front wheel 13 and the trolley 11. 13 and rear wheel 14
The width is increased so that it can support and guide both.

Of course, contrary to the above, the spacing between the front wheels may be larger than the spacing between the rear wheels.

According to the conveyor device configured as described above, as the driving trolley 1 and the driven trolley 11 move, the front wheels 3,
13 and the rear wheels 4 and 14 are formed in parallel.

In the above embodiment, each trolley has a plurality of horizontal wheels having a plurality of types in terms of lateral positions on the same guide rail. Since a large number of trolleys guided by the drive trolley 1 and guide rails 13 and 14 are used, one trolley with a wheel pivoted on the inner rolling path on the guide rail and the other with a wheel supporting the outer rolling path. The pivotally supported To01J-
For example, they can be arranged alternately to form one conveyor device.

Also, as shown in FIG. 4, a drive chain 18 with a pusher 17 is connected to the drive chain 18, which has an I-shaped cross section, via a horizontal axis wheel 21.22 of a trolley 19.20 connected to the chain in front and rear positions of the pusher. Guide rail 23
A conveyance transport system consisting of a trolley 25 that is movably suspended from the trolley 25 and has a driven dog 24 that engages with the pusher 17, and a trolley 25 that is connected to the trolley 25 via a work suspension member 26. Also in the conventionally known conveyor device, the body 28 is movably supported and guided by a pair of left and right guide rails 33 having a U-shaped cross section via horizontal wheels 29 to 32 pivotally supported on each trolley 25, 27. The present invention can be applied and implemented.

In this case, the wheels 29 to 32 of the trolley 25.27 may be constructed in the same manner as in the previous embodiment, and the wheels 21 and 22 of the trolley 19.20 may be arranged in left and right pairs as shown in FIG. The trolley 19 has a narrow spacing between the wheels 21 and the trolley 20 has a wide spacing between the left and right wheels 22, and the guide rail 23 is wide enough to support and guide both trolleys 19 and 20. Just configure it.

The device of the present invention can be implemented as described above, and the horizontal axis wheel supported by the trolley is attached so that a plurality of wheel transfer trajectories parallel to each other in the horizontal direction are formed on the same guide rail. , there are multiple types of lateral positions on the same guide rail (for the conveyor system as a whole). Compared to the case where all the wheels guided by the guide rail roll, the degree of wear on the wheel rolling surface of the guide rail is significantly reduced, and the service life of the guide rail is significantly improved.
