Abstract

PURPOSE:To prevent a workpiece and an abradant from falling off by providing projection pieces on end edges of a pair of belt conveyors rotating in succession at different speeds in close vicinity to each other or in sliding with each other respectively in directions of opposing belts. CONSTITUTION:Thrown a workpiece (a) into a workpiece throwing part 14 together with abradant particles (b), they are fed between curved cross sectional parts 12, 13 both endless belts 5, 9. In succession, the workpiece (a) is brought into sliding contact with the abradant particles (b) and an abrasive layer 16 applied on both the belt surfaces due to different travelling speeds of both the belts, or the workpiece (a) is abraded owing to relative sliding thereof and discharged from a workpiece discharge position 15. In addition, the workpiece (a) and the abradant particles (b) entered in directions of end edges of both the belts 5, 9 upon conveyance and processing thereof are prevented from falling off from side edge parts of the belts since edge grooved projection edges 10, 11 are fitted to each other over the whole length of a conveyor part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying and processing device, which grinds the surface and circumferential surface of a workpiece by rubbing while conveying the workpiece over a predetermined distance. The purpose is to provide transportation and processing equipment.

That is, the conveying and processing apparatus of the present invention drives a pair of belt conveyors that continuously circulate in close proximity or in sliding contact in the same direction or in different directions, and also drives steel balls or straw between the two belts.・Supplies workpieces such as nuts and nuts,
The surface of the workpiece is rubbed by the drive of both belts, and the surface of the workpiece is conveyed through a predetermined section while being subjected to cutting and grinding. Various types of polishing are applied to the surfaces of both belts as necessary. It is designed to supply an abrasive layer, etc., between both belts together with the material to be carated, and protrusions or grooves, etc., are provided on the edges of both belts, respectively, protruding toward the opposite belt. An interdigitated edge structure is formed to prevent the workpiece and the abrasive from spilling out.

Hereinafter, embodiments of the device of the present invention will be described with reference to the drawings.
FIGS. 1 to 3 show a horizontally placed conveying and processing device according to a first embodiment. (1) is the lower belt conveyor, (2J
id is an upper belt conveyor, and a lower belt conveyor (1) is connected to a drive belt wheel (3) (4), and an endless belt (5) is connected between a number of intermediate rollers (6) (61).
The drive belt pulley (3) (41) of the upper belt conveyor (2) is supported so that it does not bend and fall due to its own weight. The endless belt (9) is positioned so that the lower belt rubs against the upper surface of the endless belt (5) of the lower belt conveyor (1), and the endless belt (9) is flexed and lowered by its own weight. The two endless belts (51 (9)) are slidably rubbed over the entire sliding contact position of the two endless belts (51 (9)). A fitting edge is formed that fits into the groove-shaped protruding edge Qlull formed on the endless belt (5) (9), and the center portion of the endless belt (5) (9) is recessed in a phase manner. It has a gently curved cross section (121as shape) in the direction of

Further, in both of the belt conveyors (1) and (2), the lower belt conveyor (1) protrudes at the workpiece input section a, and the upper belt conveyor (2) protrudes at the workpiece discharge position α9. ) are prominent. The above endless belt (5) (91
0 surface is coated with various abrasive layers (16) such as abrasive granules, puffs, brushes, etc. depending on the type of processing.
Both belt conveyors (1) and (2) are driven by a rotational drive device such as a motor (not shown).
) (Through the force (8), the endless belts (5) and (9) are driven to travel in the same direction or in different directions at different speeds depending on the cutting time and type of processing.

A workpiece (a), such as a pressed washer, is placed in the abrasive layer (b
), it is fed between the curved section α21 (131) of both endless belts l-+5) (9), and due to the difference in running speed of the upper and lower endless belts (5) and (9), the temporary workpiece (
a) rubs against the abrasive layer U (to) and abrasive layer (b) provided on the surface of the endless belt (5) (91), or rubs against the workpiece (
a) The surface of the pressed article is polished or ground by Doshi Kyozuri, and at the same time, the surface of the pressed article is deburred and chamfered. The object (a) is transferred in the direction of the workpiece discharge position (15), and the workpiece discharge position U
It is discharged from υ together with the abrasive particles b). In addition, during the above-mentioned conveyance and processing, the workpiece (a), abrasive layer (bl, etc.) that has penetrated toward the edge of the double endless belt (51 (91), etc. is Because they fit together, it is possible to prevent them from falling from the side edges due to the fit.
It is also possible to supply various types of fluid polishing liquid together with the shin-ken material particles (b).

Next, FIG. 4 shows an embodiment of the vertical conveyance and processing apparatus of the present invention, which is particularly adapted to process a workpiece while conveying it vertically.

Further, side 5, Fig. 1d, shows a structure in which one endless belt (5) is inscribed in the other endless belt (9).

In addition, the structure of the fitting edge is not only the grooved protruding edge (10) (1υ) as shown in FIG. 43 but also the grooved edge (1υ) as shown in FIG.
Various configurations can be made, such as a fitted combination of 0a) and a protrusion (lla), and a combination of a rectangular cross section (10b) (llb) as shown in FIG.

Next, FIGS. 8 to 10 show examples of combinations of cross-sectional shapes of both endless belts (51 (9)). The figure shows one having a large number of uneven stripes (12a) (13a), and FIG. 10 shows one with uneven surfaces (12b) (13b).

As described above, according to the invention, the workpiece can be transported to a desired position in the vertical and horizontal directions while performing deburring, surface grinding, polishing, etc. Not only that, but the structure is simple and the shape of the belt conveyor can be changed in various ways depending on the conveyance position, and the practical effects of the invention are extremely large.
