The fall prevention wall 1 is provided on the outer side of the side circular plate 11.
3 are provided along the circumferential direction. Similarly, on the outer side of the disk 11 on the rear side, the work 1 is prevented from dropping backward from a position rotated one pitch from the work insertion position A to a position one pitch before the work ejection position B. Therefore, a fall prevention wall 13 is provided.

Cup-shaped part 1a from the side opening
Stored with the side in front. At the work input position A, the storage chamber 5 is in an inclined state in which the rear side is slightly higher than the front side, so that the work 1 is smoothly stored by sliding on the inner wall surface of the tubular body 12. However, a work input pusher may be provided on the rear side to input the work. Then, the opening edge portion of the cup-shaped portion 1 a hits the front fall prevention wall 13 and stops, and the cup-shaped portion 1 a is stored in a sideways state and is sent to the lower warm bath 4 as the rotary drum 3 rotates.

らのワーク１の脱落が防止される。The work 1 passes through the hot water of the hot tub 4 as the rotary drum 3 rotates while the work 1 is lying down. here,
The state of the storage chamber 5 gradually changes as the rotary drum 3 rotates, and when it reaches the lowermost position immediately below the rotation center shaft 2, the storage chamber 5 is inclined so that the front side is positioned higher than the rear side. There is. In this state, since the opening of the cup-shaped portion 1a is directed obliquely upward, air is not accumulated in the cup-shaped portion 1a, and hot water is surely brought into contact with the entire surface of the cup-shaped portion 1a,
The entire work 1 can be heated substantially uniformly and quickly. Even if the storage chamber 5 is inclined, the fall prevention wall 13 provided outside the rear disk 11 prevents the work 1 from falling out of the rear opening of the storage chamber 5.

下流の潤滑剤塗布装置に搬送される。The work 1 heated to a predetermined temperature by the warm bath while passing through the hot water is discharged from the front opening at the work discharge position B onto the conveyor 14. At the work discharge position B, as shown in FIG.
On the contrary to the inside of the hot water, the storage chamber 5 is inclined so that its front side is positioned lower than its rear side, so that the opening of the cup-shaped portion 1a is directed obliquely downward and the hot water is surely poured from the inside of the cup-shaped portion 1a. Is discharged. Therefore, even if the work 1 has the cup-shaped portion 1a, it can be dried quickly after the warm bath. Further, up to one pitch before the work discharge position B, the fall prevention wall 13 disposed on the front side prevents the work 1 from falling off to the front side. At the work discharge position B, since the fall prevention wall 13 does not exist on the front side of the work discharge position B, the work 1 naturally slides toward the front side due to its own weight and is placed on the transport conveyor 14. However, similarly to the work input position A, a work discharge pusher may be provided on the rear side and the work 1 may be pushed from the rear side by the pusher and discharged. In any case, since the storage chamber 5 is inclined downward to the discharge side at the work discharge position B, the work can be easily discharged.
In this way, the work 1 is sequentially transported by the transport conveyor 14 to the lubricant applying device on the downstream side.

余剰分を吹き飛ばすようにすることもできる。Although the heating device using the rotary drum 3 for transporting the work has been described above, the lubricant applying device may be configured using the same rotary drum 3. That is,
The hot tub 4 in the heating device may be a lubricating tub that stores a lubricant instead of hot water. The lubricant can be applied to the work 1 by passing the lubricant as the rotary drum 3 rotates while the work 1 is stored in the storage chamber 5. However, the area of the rotary drum 3 which is immersed in the lubricant may be smaller than that of the heating device. In this case as well, the effect of tilting the storage chamber 5 can be similarly obtained. That is, since the opening of the cup-shaped portion 1a is directed obliquely upward in the state where the cup-shaped portion 1a is immersed in the lubricant, it is possible to reliably prevent the occurrence of air accumulation in the cup-shaped portion 1a. In this case, even if the work 1 is not in the shape of a stepped rod but in a straight shape (having a constant diameter), the opening of the cup-shaped portion 1a faces upward, so that the occurrence of air accumulation can be prevented. Therefore, the lubricant can be surely applied to the inner surface of the cup-shaped portion 1a, which is a difficult area to apply, and uneven application can be prevented. Further, as the storage chamber 5 passes through the lubricant and is positioned above the rotation center shaft 2, the opening of the cup-shaped portion 1a gradually starts to face downward, and the work discharge position B
Since it is directed obliquely downward, the excess lubricant is reliably discharged from the inside of the cup-shaped portion 1a before reaching the work discharge position B. As described above, since it is possible to prevent the lubricant from accumulating in the cup-shaped portion 1a, the lubricant can be uniformly applied to the entire work 1 and the subsequent drying time can be shortened. The film thickness of the dry film of the lubricant formed can be made uniform. A liquid draining zone for removing an excess of the lubricant applied to the work 1 may be provided from a position where the storage chamber 5 is upward from the liquid level to a position just before one pitch of the work discharge position B. Further, it is also possible to provide an air blower as a liquid draining means in the liquid draining zone to blow off the surplus portion with high pressure air.
