Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pallet for conveying workpieces and the like along the rails of a conveyor equipped with a driving means.

[Prior Art] For example, as disclosed in Japanese Unexamined Patent Publication No. 59-34972, pallets are sent along a rail by a conveyor drive means, and a pallet is conveyed along a rail by a driving wheel that supports the pallet on the rail, and a running wheel that sandwiches the rail from both sides. The base plate is equipped with a pair of guide wheels and a drive wheel that transmits driving force to the pallet.

As shown in FIG. 3, the pallet 1 has a frame 3 integrally formed on the bottom wall of a base plate 2 by die-casting or the like. Drill a hole in the mounting wall 5 of the frame 3,
Components such as running wheels 6 and guide wheels 7 are attached with bolts.

[Problems to be solved by the invention] The above-mentioned pallets require various processing on the base plate, and when die-casting the base plate, a mold is required for each type of pallet, making the processing complicated. , which is unfavorable in terms of cost.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a pallet in which the constituent elements of the pallet are unitized to simplify processing and assembly, thereby reducing costs.

[Means for solving the problem] In order to achieve the above object, the configuration of the present invention is to provide a plurality of positioning grooves in the bottom wall of the bed plate, guide and support the bed plate on the rail, and provide a driving force that provides propulsion. A protrusion is formed on the upper wall of the frame of each wheel unit, guide wheel unit, and drive wheel unit, and the protrusion on the frame of each wheel unit is engaged with the positioning groove of the base plate. The top wall of the frame is overlapped with the bottom wall of the base plate and fastened with bolts.

[Operation] A pallet of each specification is constructed by selecting pre-standardized components such as a running wheel unit, a driving wheel unit, a guide/running wheel unit, etc., and assembling them on a base plate having the required shape and dimensions.

[Example of the invention] Figure 1 is a perspective view of a pallet according to the invention, and Figure 2 is a perspective view of a pallet according to the invention.
The figure is an exploded perspective view of the same pallet. Palette 1
0 is composed of a base plate 11, a running wheel unit 12, a driving wheel unit 13, and a guide/running wheel unit 14. Bolt insertion holes 15 are provided in the base plate 11 for attaching each wheel unit 12 to 14, and the base plate 1
A positioning groove (not shown) is machined in the bottom wall of 1.
Projections 16 that engage with the positioning grooves of the base plate 11 described above are formed on the upper walls of the frames of the running wheel unit 12, drive wheel unit 13, and guide/running wheel unit 14. A running wheel 17 for each wheel unit 12 to 14,
Attach the drive wheel 18, guide wheel 19, and running wheel 20.

To attach each of the wheel units 12 to 14 to the base plate 11, the protrusions 16 of each of the wheel units 12 to 14 are engaged with the positioning grooves of the base plate 11, and the bolts 21 inserted into the bolt insertion holes 15 of the base plate 11 are inserted. are fastened to the screw holes of each wheel unit 12-14.

[Effects of the invention] As described above, the present invention provides a plurality of positioning grooves on the bottom wall of the base plate, and also includes a running wheel unit, a guide wheel unit, and a driving wheel that guide and support the base plate on the rail and provide propulsion. A protrusion is formed on the upper wall of the frame of each wheel unit of the unit, and the protrusion on the frame of each wheel unit is engaged with the positioning groove of the base plate, and the upper wall of the frame of each wheel unit is aligned with the bottom of the base plate. Once stacked on the wall and fastened with bolts, pallets with different specifications can be created by selecting pre-standardized components such as the running wheel unit, driving wheel unit, and guide wheel unit and assembling them onto a base plate of the required shape and dimensions. This eliminates the need for a conventional mold for molding the base plate.
Processing and assembly can be simplified and costs can be reduced.

The wheel unit can be accurately connected to the base plate by simply machining positioning grooves and bolt insertion holes in the bottom wall of the base plate of any shape and size.
