The guide plate 42 is inclined downward from the horizontal shaft 4 toward the cleaning water tank 32, and 42 is an air vent provided in the casing 1. Hole 43, a short pipe receiving carriage 43, and θ an angle at which the basket 7 reciprocates.

Next, the operation of the present invention will be described.

For example, the short pipe P processed by the NC lathe is conveyed by the conveyor 18 and supplied from the conveyor 18 to the guide frame 20 of the orientation correcting device 19. In this case, the piston rods 24a ′, 24 of the fluid pressure cylinders 24a, 24b
b'is the most protruding (see FIG. 6), and the orientation correction plates 23a, 2
The inner width X of 3b is the widest.

When the short pipe P is supplied to the guide frame 20, the fluid pressure cylinders 24a and 24b are actuated to operate the piston rod 2.
4a ′ and 24b ′ retreat and repeat forward. For this reason,
The straightening plates 23a and 23b reciprocate from the solid line position in FIG. 6 in the direction of the virtual line, and as a result, the short pipe P is forcibly straightened in a direction horizontal to the horizontal axis 4. After straightening, the orientation straightening plates 23a and 23b stop in the open state.

When the short pipe P is straightened in a direction substantially parallel to the horizontal axis 4, the basket 7 is stopped in the state shown by the solid line in FIG. 1, and the fluid pressure cylinder 16 is operated to open the opening / closing shutter 17 on the inlet side. open. Then, the short pipe P rolls in the guide frame 20 and rolls into the basket 7 through an opening (not shown) provided in the front surface of the casing 1 on the inlet side.

When the short pipe P moves into the basket 7, the inlet-side opening / closing shutter 17 is closed by the fluid pressure cylinder 16 and the geared motor 8 is driven. Therefore, the pulley 9, the timing belt 12, the pulley 11, the speed reducer 10,
The horizontal shaft 4 rotates through the pulley 13, the timing belt 15, and the pulley 14, and the basket 7 rotates above the horizontal shaft 4.

When the basket 7 is located above the horizontal shaft 4, the geared motor 8 is rotated in the forward and reverse directions to reciprocate the basket 7 back and forth about the vertical axis of the fluid pressure cylinder 31 at an angle of 1 / 2θ. The cleaning water pump 34 is driven at the same time. In addition, the movement distance by rotating 1 / 2θ is about 70 mm, and one reciprocation is performed in about 1 second.

When the cleaning water pump 34 is driven while the basket 7 is reciprocating, the warm water heated to about 50 ° C. by the heater 33 is supplied from the conduit 35 and the flexible tube 36 to the cleaning water injection nozzle. Sent to 30
The cleaning water W is sprayed from the cleaning water spray nozzle 30 toward the short pipe P as cleaning water W. At this time, the fluid pressure cylinder 31 is operated to repeatedly reciprocate up and down the wash water injection nozzle 30 within the range of the stroke S1 (about 50 mm), and the basket 7 or the short pipe P is reciprocated back and forth at an angle of θ by driving the geared motor 8. Therefore, the cleaning water W is sprayed on the outer surface and the inner surface of the short pipe P over the entire circumference, and the cutting oil adhering to the short pipe P is removed.

The water for cleaning the short pipe P flows through the guide plate 41 and is returned to the cleaning water tank 32 through a filter (not shown).

When the washing of the short pipe P is completed, the fluid pressure cylinder 31 and the washing water pump 34 are stopped, the geared motor 8 is rotated in the forward and reverse directions to reciprocate the basket 7 at an angle θ, and the fluid pressure cylinder 38 is moved to the stroke S2. (About 50m
Repeatedly reciprocating up and down in the range of m), from the compressor to the pipeline 4
0, compressed air is supplied to the dry air jet nozzle 37 via the flexible tube 39. Therefore, the compressed air is jetted as the dry air A from the dry air jet nozzle 37 and is blown to the outer surface and the inner surface of the short pipe P over the entire circumference, so that the short pipe P is dried. At this time, since the temperature of the short pipe P is about 50 ° C., it is dried quickly.

When the drying of the short pipe P is completed, the basket 7 is moved into the casing 1 by driving the geared motor 8.
Rotate to the exit side. Therefore, when the fluid pressure cylinder 26 is operated to open the outlet-side opening / closing shutter 28, the short pipe P in the basket 7 rolls toward the outlet side of the casing 1, passes through an opening (not shown) of the casing 1, and is further guided. The frame 29 is rolled and supplied to the short pipe receiving carriage 43.

According to the embodiment of the present invention, the short pipe P on which dirt such as cutting oil is attached can be automatically and easily washed, and no detergent is required, which is economical. The washing water is drained well, the direction of the short pipe can be accurately corrected, the short pipe can be supplied to the basket and delivered from the basket to the guide frame reliably, and the short pipe can be dried after washing. Can be done quickly.

The embodiment of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
