摘要:
The present invention provides an apparatus for removing the unnecessary thin-film layer on the periphery of the substrate of the plate-like member having a square shape, on the surface of which substrate is formed a thin-film layer. The apparatus comprises a chamber to treat the peripheral part where the peripheral part of the plate-like member is inserted and where the unnecessary thin-film layer on the peripheral part of the plate-like member is removed; and a means to move the plate-like member. The chamber to treat the peripheral part comprises a cover to prevent the scattering of the sprayed particles and the dust for treating the peripheral part, the cover having one of its end-sides that forms a ceiling being closed and having the other end-side that is opposed to the ceiling being open and a suctioning cover for treating the peripheral part, having an opening that has the same shape as the opening of the cover to prevent the scattering of the dust. In the chamber to treat the peripheral part, a blasting nozzle for spraying particles for treating the peripheral part is disposed on the cover to prevent the scattering of the dust, so that the mouth of the blasting nozzle is covered by the wall of the cover to prevent the scattering of the sprayed particles and the dust.

A method and apparatus of manufacturing an endless metallic belt adjusts a circumferential length of the belt by subjecting the endless metallic belt to a shot peening treatment. For example, by measuring the circumferential length prior to the shot peening treatment and determining the condition of the shot peening treatment on the basis of the measured length, and/or by measuring the circumferential length during the shot peening treatment and terminating the shot peening treatment on the basis of the measured length.

A method and apparatus for cleaning a succession of workpieces such as automobile engine blocks includes a first cleaning mechanism wherein cleaning media such as steel shot is directed against the workpieces. After being discharged from the first cleaning mechanism, the workpieces are inverted and passed through a second cleaning mechanism where cleaning media again is directed against the workpieces. In the second cleaning mechanism, the workpieces are separated so that the ends of the workpieces can be cleaned. The invention includes turning mechanisms for inverting the workpieces one-by-one, as well as devices for controlling the movement of the workpieces through the different cleaning and turning mechanisms.

The apparatus comprises one or more blasting cabins through which are conveyed workpiece carriers in the form of grate bars secured only at one end to a conveyor chain. A shifting device transfers workpieces from a first to a second conveyor for a second pass through such cabin. A turning device turns the workpieces over during such transfer. Said device comprises a box which is rotated about a horizontal axis and chutes each workpiece onto the second conveyor.

A turnover mechanism is configured to receive and flip over parts delivered by an in-feed conveyor to an out-feed conveyor. The turnover mechanism includes a frame and a gripper assembly coupled to the frame. The gripper assembly is configured to secure and move a part having one surface treated from the in-feed conveyor. The turnover mechanism further includes a flipper assembly coupled to the frame, the flipper assembly being configured to rotate and deliver the part to the out-feed conveyor with an opposite surface of the part exposed for treatment.

A continuous shot-blasting machine for surface treating arbitrarily arranged batches of workpieces includes at least one blasting chamber for shot-blasting the workpieces and a turn-over device for turning over the workpieces to expose all surfaces for treatment. A pair of supporting racks carry the workpieces along a conveyor to and from the blasting chamber. The workpieces are carried on one of the supporting racks through the chamber for blasting treatment of their exposed surfaces and after being turned over are carried on the other supporting rack through the same chamber or through a second chamber for blasting treatment of the newly exposed surfaces. The turn-over device rotates the first supporting rack and workpieces through 180 degrees about a substantially horizontal axis after the first shot-blasting treatment to turn the workpieces over for deposit onto the other supporting rack. The turn-over device includes electromagnetic or hydraulic members for holding the workpieces on the supporting rack during the turning operation, and for releasing the workpieces from the supporting rack after being turned over to expose the untreated surfaces.

A blanked plate-like metal member for use as an element of a belt in a continuously variable transmission has an recess including an undercut therein. A stream of a liquid mixed with particle members is ejected toward an edge to be beveled of the recess thereby to bevel the recess. After the edge is beveled by deburring the edge, the recess is finished by removing a bulge formed on an outer surface of the edge by deburring the edge.
摘要:
Apparatus (10) is provided for cleaning of dirty, clogged sandpaper, particularly large, industrial size sandpaper belts (190) used in furniture making operations. The apparatus (10) includes a drum (58) adapted to support a belt (190), together with blasting means (16) adjacent the drum (58) for creating a stream of particulates directed toward a portion of the belt (190) for cleaning purposes. Positioning means (18) is also provided for selectively changing the relative orientation of the blasting means (16) and the belt (190) in order successively clean different portions of the belt (190). Preferably, a laterally reciprocal nozzle (108) is employed for creating the particulate stream, and the belt (190) is intermittently shifted via a pneumatic mechanism (158) to present successive portions of the belt (190) for cleaning thereof. Dislodged material and dust is conveyed from the apparatus (10) through a port (42), whereas the particulate cleaning media is collected in a lower hopper (50) for recirculation to the nozzle (108 ).
