The front attachments (third restricting means) 53 are configured to face each other and face the end surface W′1 on the combustion chamber side of the cylinder head W ′.

  Next, the operation of the cylinder head cleaning apparatus 1 having the above configuration will be described.

  First, the cylinder head W before cleaning is placed on the pallet 31 at the mounting stage S1, and supported in a standing posture. Then, it is conveyed downstream by the carry-in conveyor unit 11 and delivered to the upstream end of the cleaning conveyor unit 12.

  When the cleaning conveyor 12 receives the pallet 31 from the carry-in conveyor 11, the door 7 of the cleaning booth 2 moves upward to open the upstream opening 5 a of the box 5. Then, the cleaning conveyor unit 12 is driven to carry the pallet 31 into the box 5, and the pallet 31 on which the cylinder head W is placed is stopped at a cleaning position set in advance in the cleaning booth 2.

  In the cleaning booth 2, when the upstream opening 5 a is closed by the door portion 7, the cylinder head W is cleaned by the cleaning device 21. Here, since the cylinder head W is supported on the pallet 31 in an upright posture in which the camshaft rotation center axis L extends in the vertical direction, the cleaning liquid sprayed onto the cylinder head W by the cleaning device 21 is Without remaining in the head W, it can flow down from above. At that time, the cleaning liquid that has flowed into the camshaft bearing portion can flow down from the through hole 45 b of the horizontal attachment 45 through the opening 44 of the support substrate 43.

  The cleaning liquid that has flowed down from the cylinder head W passes through the opening hole 32 a and flows down to the lower side of the base plate 32. Therefore, the pallet 31 can quickly drain the cleaning liquid that has flowed down from the cylinder head W, and the cylinder head W after cleaning can be quickly drained from the cleaning booth 2 to the draining and drying booth 3 without using a conventional reversing device. Can be conveyed.

  The cylinder head W is transported to the draining / drying booth 3 after being washed by spraying the cleaning liquid for a predetermined time in the cleaning booth 2. In the draining / drying booth 3, air is blown to the cylinder head W after cleaning by the air blow device 22, and draining / drying is performed.

  Since the cylinder head W is supported in a standing posture by the pallet 31, the cleaning liquid does not accumulate in the cylinder head W, and can be drained and dried in an extremely short time. Therefore, the operation time of the air blow device 22 can be shortened, and energy saving of the entire device can be achieved.

  When the cylinder head W receives air blow for a predetermined time in the draining / drying booth 3 and drains and drys, the pallet 31 is unloaded from the draining / drying booth 3 and conveyed to the downstream end of the cleaning conveyor unit 12. It is placed on the upstream end of the carry-out conveyor section 13 at the downstream end. The carry-out conveyor unit 13 conveys the pallet 31 to the downstream end and delivers it to the return conveyor unit 14, and the return conveyor unit 14 conveys the pallet 31 to the take-out stage S <b> 2 upstream of the carry-in conveyor unit 11.

  Then, the pallet 31 is stopped at the take-out stage S2, and the cylinder head W after washing is taken out from the pallet 31. The pallet 31 from which the cylinder head W has been taken out is conveyed from the take-out stage S2 to the mounting stage S1 by the carry-in conveyor unit 11, and the cylinder head W before cleaning is again mounted on the mounting stage S1.

  According to the cylinder head cleaning device having the above configuration, since the pallet 31 supports the cylinder head W in the standing posture, the cleaning liquid sprayed by the cleaning device 21 is allowed to actively flow down toward the lower side of the cylinder head W. It is possible to prevent the cleaning liquid from remaining in the cylinder head W.

  Therefore, the conventional reversing device for reversing the workpiece can be omitted, and the entire device can be miniaturized. Therefore, an installation space can be easily secured and installation can be simplified.

  In addition, since the cleaning liquid can be actively flowed down from the cylinder head W, the cleaning liquid is taken out from the cleaning booth 2 in a state where the cleaning liquid is accumulated in the cylinder head W or is scattered to the surroundings to cause troubles in other devices. It can be prevented from occurring.

  Moreover, draining and drying by the air blow device after cleaning can be completed quickly. Therefore, energy saving of the entire apparatus can be achieved, and the cycle time in the cleaning process of the cylinder head W can be shortened.

  Further, the pallet 31 in the present embodiment corresponds to the two types of cylinder heads W and W ′, and has a configuration in which each is supported in a standing posture state. Therefore, the pallet 31 can be shared, and it is not necessary to prepare the pallets 31 corresponding to the type of work, and space saving can be achieved.

  Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the case where the transfer device 4 has a circumferential transfer path has been described as an example, but the transfer device 4 may extend in a straight line.
