Inverted DI cans are fed by a conveyer having partitions in a plurality of rows such that they are spaced apart in each row, and treatment liquid is sprayed against the travelling cans from above and below the center of each row. The liquid is sprayed from above in a uniform and a full-cone pattern greater in area than the top surface of the can and from below also in a full-cone pattern or in a fan-shaped pattern narrow in the widthwise direction of the conveyer and greater in length than the can open end diameter. The liquid is further sprayed against the travelling cans from side nozzles on the opposite sides of and symmetric with respect to the center of each row. The side walls of the cans are thus washed without contact of adjacent cans in the direction of travel of the cans. The washing force is increased in the space between adjacent cans in the direction of travel to prevent washing irregularities and thus permit uniform surface treatment of the inner and outer surfaces of the cans.

The present invention provides a capacitor charging circuit for a discharge type welding tool. The circuit includes a rectifier for producing rectified pulsating currents, a capacitor to be charged, a thyristor between the rectifier and the capacitor. A pulse generator receives the pulsating currents and in turn produces a pulse at each hill of the pulsating current. The thus produced pulse is applied to the gate of the thyristor which turns the thyristor on. A charge potential detecting circuit directly measures the charge potential across the charged capacitor and transfers a signal change, according to the level of the capacitor potential, to the pulse generator so as to thereby control the timing of the pulse generation at each hill of the pulsating current.

An arc stud welding device and method are provided, in which a stud is pulled up to an appropriate predetermined height, even after a portion of a flexible base material is dented by the stud and has returned to an original flat condition. A controller operates a linear motor to disengage the stud from the base material, operates a power source to generate a pilot arc and a main arc, and reverses the operation of the linear motor to press the stud against the base material for welding. When the stud is pulled up from the base material, the controller detects the position of disengagement of the stud from the base material, and the linear motor pulls up the stud to a predetermined position.

A self-piercing type rivet setting system 30 comprises: a rivet swaging assembly 35; a robot 6 which moves the rivet swaging assembly 35 to put it in position relative to a predetermined site on a workpiece to be riveted; a single integrated controller 31 made up by an integration of a controller for controlling a riveting operation of the rivet swaging assembly and a controller for controlling the motion of the robot; and a rivet feeder 9 for automatically feeding a self-piercing type rivet to the rivet swaging assembly. From the integrated controller 31, a interface cable 33 extends to the robot 6 and another interface cable 34 extends to the rivet feeder 9, and the rivet swaging assembly 35 is integrally incorporated into the robot 6.

A belt includes a plurality of rows of endless chains and can body conveying sections each defined between adjacent ones of the chains. Each of the endless chains are formed includes a plurality of U-shaped unit members each having a bottom fitted in an open end portion of a preceding one in the row, the engaged portions of the preceding and succeeding unit members being connected together by a plurality of rotatable connecting rods common to the chains. Intermediate rods having a length a little greater than the can body diameter are each provided between adjacent ones of the rods of the chains and also being opposed unit members of adjacent chains. The intermediate rods are disposed at a common elevation as the connecting rods beneath the top of the chains. Thus, the conveyer belt can convey can bodies in a plurality of rows in which the can bodies will not touch each other at the open ends of these can bodies.
