The pallet 31 has a flat plate drum mounting portion 31a and a pair of legs 31b and 31b provided on each side portion of the drum mounting portion 31a in the width direction. Each leg 31b is placed on each roller chain 11. Engaging grooves 31d extending in the horizontal direction are provided on the outer surface of each leg 31b.

As shown in FIG. 3, the drum mounting portion 31a of the pallet 31 is provided with a large number of through holes 31c penetrating in the vertical direction at intervals of, for example, 5 mm. A support pin 32 formed of a magnet is fitted in 31c. A flange portion 32a is provided at a lower end portion of each support pin 32 so that the flange portion 32a is not fitted in each through hole 31c. Since each support pin 32 is composed of a magnet, it is in a state of being attracted to the drum mounting portion 31a of the magnetic pallet 31 by magnetic force, and there is a risk that it will fall out from the through hole 31c of the drum mounting portion 31a. Absent. Then, when an appropriate pushing down pressure is applied to each support pin 32, each support pin 32 is pushed down against the magnetic force applied to the drum mounting portion 31a.

Each roller chain 11 is in a state in which its outer portion is covered by the guide body 12. Then, at the position where the drum 70 is placed on the pallet 31 of the drum transport tool 30 transported by each roller chain 11, it is arranged horizontally between the roller chains 11 so as to be vertically movable. A flat plate-shaped pressing plate 50 is provided. The pressing plate 50 is connected to a piston rod 61 of an air cylinder 60 provided below the pressing plate 50, and is vertically moved by the air cylinder 60. The upper surface of the pressing plate 50 has the same size as the drum mounting portion 31a of the pallet 31 conveyed by each roller chain 11, and when it is moved upward by the air cylinder 60, it is placed on the drum mounting portion 31a. The flange portions 32a of the support pins 32 of the portion 31a are brought into contact with each other so that the flange portions 32a come into contact with the lower surface of the drum mounting portion 31a. Then, when the flange portion 32a comes into contact with the lower surface of the drum mounting portion 31a, the support pin 32 projects upward from the drum mounting portion 31a by a predetermined amount.

As a result, even if any flange portion 32a of the support pin 32 of the drum transport tool 30 is in a state of being lowered from the lower surface of the drum mounting portion 31a of the pallet 31, the flange portion 32a of the support pin 32 is pressed. Pressed by plate 50. At this time, the pallet 31 is in a state in which the engagement groove 31d provided in each leg portion 31b is engaged with the upper portion of the locking body 20, so that the pallet 30 is not moved upward and the pallet 31 is not magnetically moved. The support pin 32 attracted to the drum mounting portion 31a of the pallet 31 is lifted. The flange portions 32a of the raised support pins 32 are brought into contact with the lower surface of the drum mounting portion 31a. As a result, all the support pins 32 are in a state of protruding by a predetermined amount from the drum mounting portion 31a. After that, the air cylinder 60 is driven and the pressing plate 50 is lowered.

In such a state, the drum 70 is vertically lowered from above each support pin 32, and each support pin 32 with which the lower end surface of the drum 70 is contacted is pushed down by the drum 70 and lowered. The lower end of the drum 70 is located in the annular recess formed by each of the support pins 32. In this state, the lower end of the drum 70 is held by the support pins 32 protruding upward from the drum mounting portion 31a, so that the drum 70 is vertically supported.

In this way, when a predetermined number of drums 70 are vertically supported on the drum mounting portion 31a of the pallet 31, each roller chain 11 is driven and the drum transport tool 30 is moved to the next step. The drum 70 is conveyed to the coating process. In this coating step, a chucking mechanism is inserted from the upper end of the drum 70 vertically supported on the drum transport tool 30, and the drum is chucked from the inner peripheral surface of the drum 70. Then, by raising the chucking mechanism, the drum 70 is detached from the drum transport tool 30.
