Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for circulating and transferring a plurality of coating hangers for hanging an object to be coated. 2. Description of the Related Art Conventionally, in the case of performing a coating process of parts not only in automobiles and motorcycles but also in various factory products, a coating work space including a coating facility and a ventilation facility is formed. In addition, the object to be coated is sequentially passed through the conveying line of the object to be coated, and the coating process is performed on the object to be coated sequentially. And
The object to be coated is hung on the coating hanger in consideration of the case where the object cannot be held, and the object to be coated is sequentially sent to the coating work space while being hung on the coating hanger. For this reason, a coating hanger transfer device that attaches a large number of coating hangers to a conveyor chain and circulates and transfers them is used. FIG. 6 shows a coating hanger transfer device 1 passing through a coating work space in which an upper portion is an intake portion and a lower portion is a hanging portion.
FIG. 7 shows an upper structure of the conveyor chain, in which a conveyor chain 3 is mounted on a rail 2 via a rolling member, and a mounting ring 4 having a lower end as a ring is attached to the conveyor chain 3 in its length direction. The mounting ring 4
Is hung with a paint hanger 5. Further, as shown in the drawing, the coating hanger 5 has a support rod 6 for hooking the object to be coated a, and is located at the upper end of the support rod 6 so that the coating material splash during coating adheres to the conveyor chain 3 side. And a dust umbrella 7 which suppresses the operation. Note that the support rod 6 and the umbrella 7 are connected to be separable. Then, the hook 8 that bends the tip of the dust umbrella 7 and engages with the mounting ring 4 so as to be detachable from the mounting ring 4 is raised, and even if a swing operation or a push-up operation with the coating hanger is performed during the painting operation, In order to prevent the hook 8 from being detached from the attachment ring 4 and to be able to detach the hook 8 from the attachment ring 4 when necessary, a closure using bolts and nuts as shown in FIGS. The member 9 allows the opening 10 of the hook 8 to be closed. For example, as shown in FIGS. 8 (a) and 8 (b), a nut 9a is welded and fixed to the dust umbrella 7 side, and a bolt 9b is screwed to the nut 9a.
9 comes up close to the tip of the hook 8 and rises to close the opening 10, and also, as shown in FIGS. 9A and 9B, a nut 9a is welded and fixed to the tip of the hook 8, and the nut 9a is fixed. A bolt 9b screwed into 9a protrudes toward the base end of the hook 8 to close the opening 10. As described above, the coating hanger 5 can be hung on the mounting ring 4 by the hook 8 located on the upper surface side of the dust umbrella 7, and the opening 10 of the hook 8 is closed by the closing member 9 including the nut 9a and the bolt 9b. The hook 8 is prevented from being detached from the mounting ring 4 at the time of handling the coating hanger at the time of the painting work, and the bolt 9 b of the closing member 9 is removed when necessary to open the opening 10 of the hook 8 and remove the hook 8 from the mounting ring 4. it was Tei to be able to. [0005] However, the following inconvenience has occurred due to the above-mentioned structure for mounting the coating hanger. In other words, the paint hanger is periodically removed from the conveyor chain to remove the paint adhering to the paint hanger. The bolt of the closing member is manually removed with the arm raised, and this operation must be performed for each of the paint hangers, which is a very complicated operation. In addition, since the umbrella is provided in a shape that spreads out so that the coating material does not splash onto the conveyor chain, this umbrella hinders manual work of removing the bolt of the closing member, and the position of the closing member is visually observed. In some cases, the bolt must be removed by groping in a state where it cannot be confirmed, and it has been desired that the paint hanger can be easily removed. SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to remove paint hanger without requiring manual operation by an operator, and to remove paint hanger efficiently. SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and a coating hanger having a dust umbrella at an upper end of a support rod for hanging an object to be coated is attached to a mounting ring of a conveyor chain. In a coating hanger transfer device that is hung and transferred, a hook having a bent tip and being detachably engaged with the mounting ring and supported rotatably along the transfer direction of the coating hanger on the upper surface of the dust umbrella.

An object of the present invention is to provide a coating hanger transfer device characterized in that an open state is maintained in an open state, and a coating hanger transfer device is provided. Next, the present invention will be described in detail based on an embodiment shown in FIGS. 6 to 9 are denoted by the same reference numerals, and the description thereof will be omitted. FIG. 1 shows the mounting ring 4 and the upper surface side of a dust umbrella 7 of a coating hanger 5 hung on the mounting ring 4, and a hook 8 that rises at the center of the upper surface of the dust umbrella 7 and locks on the mounting ring 4 is painted. The tip of the hanger 5 is bent forward so that the front of the hanger 5 in the transport direction X becomes the opening 10. A rotating body 11 is pivotally supported at the base end of the hook 8 so as to be rotatable in a direction along the transfer direction X. As shown, the rotating body 11 bends a rod-shaped member. Lateral part 1 formed and extending in a direction orthogonal to the transport direction X
1a and vertical portions 11b and 11c which are bent at both ends of the horizontal portion 11a in a direction orthogonal to the horizontal portion 11a, as viewed from a direction orthogonal to the transport direction X as shown in FIG. The vertical portions 11b and 11c are bent in different directions so as to obtain an open angle θ between the vertical portions 11b and 11c. Further, when the angle θ is one end, for example, when the tip of the vertical portion 11b is tilted so as to be attached to the upper surface of the umbrella 7, the other vertical portion 11c is positioned with respect to the umbrella 7 from the front in the transport direction X. Is set to be an angle close to the standing state, and the state is maintained when the rotating body 11 is rotated forward in the transport direction X and the vertical portion 11b is falling on the upper surface of the dust umbrella 7. Conversely, when the rotating body 11 is rotated backward in the transport direction X and the vertical portion 11c is falling backward, the state is maintained, and the rotating body 11 is to be rotated from the outside. As long as no force is applied, the hook 8 is positioned either forward or backward from the pivot portion side. The direction of the hook 8 and the rotating body 11
The bending directions of the vertical portions 11b and 11c are the same in any of the coating hangers 1. A hook is provided on the lateral portion 11a of the rotating body 11.
An opening / closing body 13 that rotates along the direction of the transfer direction X along with the rotation of the rotating body 11 through the vertical hole 12 that is opened at 8 is provided integrally, and the rotating body 11 is located in front of the transfer direction X. to close the opening 10 opening and closing member 13 when being is located in the opening 10 of the hook 8 and, when the rotating member 11 is positioned behind the transport direction X from the open portion 10 of the hook 8 The opening portion 10 is located at a distance behind and through the vertical hole 12 to open rearward. In FIG. 2, reference numeral 14 denotes an unlocking operation unit.
It is arranged at a required position on the transfer route of the coating hanger 5 and operates the vertical portion 11c of the rotary body 11 (the vertical portion on the side that stands up when the rotary body 11 is located in front of the transport direction X). It is provided at a position where the rotating body 11 can be rotated. The unlocking operation section 14 includes an unlocking rod 15 provided to be protrudable and retractable in a direction intersecting with the transport direction X, and an operation mechanism 16 for operating the unlocking rod 15 to protrude and retract. In the mechanism 16, the lock release rod 15 is connected to the upper end of an inverted T-shaped operation rod 16a, and the lower end of the control rod 16a is raised and lowered to make the lock release rod 15 protrude and retract. However, the operation mechanism 16 is not limited to this structure, and may be any as long as it can operate the lock release rod 15 to protrude and retract. The lock release rod 15 is positioned so as to intersect the movement locus of the vertical portion 11c of the rotating body 11 when protruded by the operation of the operation mechanism 16, and as shown in FIGS. 3 and 4. When the coating hanger 5 is transferred to the unlocking rod 15 at the time of projection while the opening 10 of the hook 8 is closed by the opening / closing body 13, the vertical portion 11 c of the rotating body 11 of the coating hanger 5 is moved. The rotating body 11 is brought into contact in the transport direction X by this contact.
And the opening / closing body 13 also turns rearward to open the opening 10. When the rotating body 11 rotates backward, the open state of the opening 10 is maintained, and the hook 8 is easily pulled out from the mounting ring 4 while holding the support bar 6 of the coating hanger 5 and the like. This makes it possible to remove the coating hangers 5 very easily. When attaching the coating hanger 5, the support rod 6
The hook 8 may be locked to the mounting ring 4 while holding the rotating body 11, and then the rotating body 11 may be rotated forward in the transport direction X. The body 13 can keep the opening 10 closed. Even if the mounting ring 4 hits the opening / closing body 13 by swinging or pushing up the coating hanger 5 in a normal coating operation in a state where the opening portion 10 is closed, the vertical portion 11b of the rotating body 11 The position of the opening / closing body 13 does not change because of contact with the dust umbrella 7, so that the hook 8 does not come off from the mounting ring 4. As described above, according to the present invention, a coating hanger having a dust umbrella at the upper end of a support rod for hanging an object to be coated is hung on a mounting ring of a conveyor chain and transferred. In the coating hanger transfer device, a hook whose tip is bent and is detachably locked to the mounting ring is supported on the upper surface of the dust umbrella so as to be rotatable along the transfer direction of the coating hanger, so that the coating hanger moves forward. Falling backward and in the transfer direction
