In FIG. 11B, a ring-shaped plate having a small diameter is stacked on the front and back surfaces with the fitting hole 29 as the center.
FIG. 11C shows the shape of a flat abacus ball.
In FIG. 11D, the front side protrusion 27 and the back side protrusion 28 are formed in a ridge shape and arranged on a circular line.
In FIG. 11E, the front side protrusion 27 and the back side protrusion 28 are made into an oval shape and are arranged on the radiation.
The fitting hole 29 is a hole having an irregular shape such as a square or a hexagon.
[0014]
The above-mentioned two-row hanger 19 can be loaded into an electrostatic coating machine (not shown) after loading the work 9 or the like by using an alignment loading device described below, It is used for usage such as unloading after completion of electrostatic coating by a coating machine.
[0015]
Here, the aligning and loading apparatus will be described with reference to the drawings.
First, a gantry 35 having an inclined wall surface 34 supported by the front leg 32 and the rear leg 33 in a state of being slightly tilted rearward is constituted, and the same line is aligned with a pair of left and right vertical lines on the inclined wall surface 34 of the gantry 35. Long V-grooved blocks 36, 37 are arranged along the upper arm and fixed to the inclined wall surface 34 using a plurality of support legs 38, 39. Three and four mounting upper plates 40 and the mounting lower plates 41 of the lower arms 5 and 6 are provided.
[0016]
Further, in the mounting upper plate 40, the upper side through which the downward shafts 7 and 8 and the hanger column 2 pass at the left and right positions corresponding to the upper end opening 42 of the left and right V-grooved blocks 36 and 37 and the middle position between these left and right positions. Cutouts 44, 45, 46 are provided, and the upward shaft 14 is provided at the left and right locations corresponding to the lower end opening 43 of the left and right V-grooved blocks 36, 37 in the lower plate 41, and at an intermediate location between these left and right locations. 15 and the lower notches 47, 48, and 49 for passing through the hanger column 2 are cut.
[0017]
In addition, the left and right air cylinders 51 and 52 are arranged in a state where the telescopic shafts 53 and 54 are movable upward at positions below the lower end opening 43 of the left and right V-grooved blocks 36 and 37 below the inclined wall surface 34. At the same time, the hook members 55 and 56 of the T-shaped hook portions 21 and 22 having a bifurcated tip are attached to the tips of the telescopic shafts 53 and 54, thereby completing the operation.
[0018]
Next, in order to load the workpiece 9 or the dummy 10 on the two-row hanger 19 using the above-described alignment loading device, first, the downward shafts 7 and 8 of the two-row hanger 19 and the upper part of the hanger column 2 are passed through the upper side. The upper arms 3 and 4 are arranged on the mounting upper plate 40 in the state where the notches 44, 45 and 46 are fitted, and the upper shafts 14 and 15 of the second row hanger 19 and the lower part of the hanger support 2 are passed through the lower side. The lower arms 5 and 6 are arranged on the mounting lower plate 41 with the notches 47, 48 and 49 fitted, and the T-shaped hook portions 21 and 22 provided at the lower ends of the upward shafts 14 and 15 are hooked members. A state in which the space between the upper center plates 12 and 13 and the lower center plates 17 and 18 is widened with the telescopic shafts 53 and 54 of the left and right air cylinders 51 and 52 shortened. And At this time, the upper center plates 12 and 13 have a positional relationship corresponding to the upper end opening ports 42 of the left and right V-grooved blocks 36 and 37, and the lower center plates 17 and 18 have a positional relationship corresponding to the lower end opening ports 43. Become.
[0019]
After placing the dummy 10 on the lower center plates 17 and 18 in such a positional relationship and inserting the upper half into the lower ends of the grooves of the V-grooved blocks 36 and 37, the dummy 10 The spacer 26 is placed on the upper end surface, the next workpiece 9 is placed on the placed spacer 26, and the whole is fitted into the grooves of the V-grooved blocks 36 and 37, and thus the spacer 26 is placed. And the workpieces 9 are alternately stacked up to a predetermined number of levels, and finally the dummy 10 is stacked.
[0020]
When the stacking is completed, the telescopic shafts 53 and 54 of the left and right air cylinders 51 and 52 are brought into an extended state. Then, the upward shafts 14 and 15 are extended by the repulsive force of the built-in coil spring 23 and the upper center plates 12 and 13 are extended. And the lower center plates 17 and 18 are narrowed, so that the stacked workpieces 9 and spacers 26 are raised so that the upper end surface of the uppermost dummy 10 is pressed against the lower surfaces of the upper center plates 12 and 13. .
[0021]
When this pressure contact is completed, the stacked workpiece 9 and the spacer 26 and the dummy 10 are maintained in the aligned state in which they are stacked up to multiple stages in the vertical direction by guiding the grooves of the V-grooved blocks 36 and 37, and the force of the coil spring 23 is maintained. It is firmly sandwiched between the upper center plates 12 and 13 and the lower center plates 17 and 18 to maintain the alignment state.
[0022]
After the alignment state is maintained, the upper shafts 14 and 15 of the two-row hanger 19 and the lower part of the hanger support 2 are removed from the lower notches 47, 48, and 49 for passing through and from the upper notches 44, 45, and 46 for passing. The two-row hanger 19 loaded with the workpieces 9 aligned in two rows is obtained by removing the downward shafts 7 and 8 of the two-row hanger 19 and the upper part of the hanger column 2. This is carried into an electrostatic coating machine (not shown), subjected to an electrostatic coating process by revolving and rotating in the same machine, etc., and used for such purposes as being taken out of the machine after completion.
