Description

[Technical field]

[0001] The present invention belongs to the technical field of slit stoppers for transport conveyors, and more particularly to a slit stopper that opens only to the minimum extent necessary and then closes a slit-shaped opening on the transport trajectory provided to avoid interference between a transport hanger or transport jig and a coating equipment ancillary device when a workpiece to be processed is transported into each coating equipment ancillary device on a transport conveyor in a coating line or processing line. [Background technology]

[0002] When the treated objects are transported through each painting equipment ancillary device 2 on a transport conveyor in a painting line or processing line, it becomes necessary to provide a gap P in a slit-shaped opening 4 provided on the transport trajectory to prevent the transport hanger 3A or transport jig 3B from interfering with the painting equipment ancillary device 2 (pre-processing device, painting booth, drying oven, processing machine, etc.) (see Figures 8 and 9). However, the gap P provided as described above can cause problems such as the intrusion of dust from the outside air, the scattering of steam and mist from inside the pretreatment device, the falling of dust that has adhered to the conveyor in the paint booth, the adhesion of paint mist to the conveyor, the loss of heat in the drying oven, and the scattering of mist from the processing machine, all of which can worsen the working environment. Therefore, measures to narrow the gap P are being implemented as shown in Figures 8A to 8D. Figure 8A is an example of a partition plate that closes the gap P in a floor conveyor, Figures 8B and 8C are examples of partition plates that close the gap P in an overhead conveyor, and Figure 8D is an example of a brush seal that closes the gap P in an overhead conveyor. In these figures, the same reference characters as those in the present invention below are used, but the reference character S indicates a partition plate and the reference character B indicates a brush seal.

[0003] As an example of the partition plate technology, the following Patent Document 1, using the reference numbers of the same document 1, discloses a coating device in which a substantially rectangular sealing plate 13 is fixed to a vertical portion in the middle of a hanger rod 11A or is supported at its center of gravity with some degree of freedom in the front-rear direction, the sealing plate 13 is attached so that its front and rear ends overlap each other in sequence to form a substantially continuous surface, and a sealing plate storage chamber 6 is provided at the top of the treatment space so as to surround the continuous sealing plate 13 from both the left and right sides. A labyrinth is formed by the top, bottom, left and right plates constituting the slit portion of this sealing plate storage chamber 6 and the left and right sides of the sealing plate 13 to improve sealing performance, and the coating device uses a continuous sealing plate on the conveyor (see claim 1, figures 1 and 2 of the same document 1).

[0004] [Patent Document 1] Japanese Patent Application Publication No. 6-277577 Summary of the Invention [Problem to be solved by the invention]

[0005] By providing the conventional partition plate S and brush seal B, the means for closing the gap P must be entirely replaced due to breakage or deterioration over time, and is inefficient. In particular, in the case of the brush seal B shown in detail in Fig. 9, as the brush seal B is used for a long time, the brush is deformed so as to bend upward or in the front-rear direction of the brush seal B, as shown in Fig. 10 at the upper part of the transfer conveyor 1. As a result, the gap P that is generated causes problems such as paint mist scattering upward within the coating equipment auxiliary device 2. Therefore, the present invention has been devised in consideration of the above-mentioned problems, and its object is to provide a slit stopper plate for a transport conveyor in which the stopper plates are arranged without gaps in the slit-shaped opening in the transport conveyor, and the stopper plates are opened only in the necessary parts to minimize gaps and preserve the working environment.

[0015] A preferred embodiment of the slit stopper plate in the transport conveyor of the present invention will be described below with reference to the drawings. This slit retaining plate opens to a minimum the slit-shaped opening 4 on the transport trajectory provided in the frame 20 of each painting equipment ancillary device 2 in order to avoid interference between the transport hanger 3A or transport jig 3B and the painting equipment ancillary device 2 (pre-processing device, painting booth, drying oven, processing machine, etc.) when the workpiece W, which is the object to be processed, is transported into each painting equipment ancillary device 2 (pre-processing device, painting booth, drying oven, processing machine, etc.) on the transport conveyor 1 of a painting line or processing line.

[0016] When a secondary hanger 15 (workpiece W, not shown) connected to a hanger 3A suspended from a conveyor chain 13 as shown in FIG. 6 passes through, or when a workpiece hanger 15' (see FIG. 8A) erected on a conveyor chain 13 mounted on a conveyor frame 14 of a transport jig 3B as shown in FIG. 7 advances, a retaining plate 5 provided on a frame 20 of the coating equipment auxiliary device 2 which forms a slit-like opening 4 through which the secondary hanger 15 or workpiece hanger 15' passes normally closes the slit-like opening 4 and opens only when the secondary hanger 15 or workpiece hanger 15' passes through the retaining plate 5, which is provided on the frame 20 of the coating equipment auxiliary device 2. In other words, as the attachment 8 attached to the transport hanger 2 or the like abuts against the storage plate 5 due to the power of the transport conveyor 1, the storage plate 5 is gradually lifted upward and opens, and after the attachment 8 has passed, the hinge-type storage plate 5 is automatically stored in its original position by its own weight and closed. A fixed rail 9 is provided in the frame 20 of the painting equipment accessory device 2 near the slit-shaped opening 4 . The transport hanger 3A or the transport jig 3B is provided with an attachment 8 that is formed in advance into a pointed shape such as a cone shape. The attachment 8 is adjusted to an optimal position by adjusting the transport speed and transport level.

[0017] This slit door plate is configured in a hinge type as shown in Figure 4. Specifically, as shown in the exploded view of FIG. 3, the storing portion of the triangular portion 50 of the storing plate 5 is rotatably connected to the hinge base portion 7 via a hinge pin 6 . The fitting plate 5 has an overall triangular shape and is formed with a triangular portion 50 that is sharpened inward (FIG. 3A), and a rectangular extended base portion 52 is formed integrally with a base portion 51 of the triangular portion 50, and a connecting protrusion 53 having an insertion hole is provided in the center of the base of the extended base portion 52. However, although not shown in the drawings, it is also possible to implement the arrangement with only the base portion 51 of the fitting plate 5 of the triangular portion 50, without forming the rectangular extended base portion 52. On the other hand, as shown in FIG. 3C, the hinge base portion 7 has an inner end of a base plate 70 having two bolt holes 70a, and each of the inner ends is formed in a recess 71 that is cut out in the center, and each end has a connection end 72 having an insertion hole. Therefore, the connection protrusion 53 of the extension base 52 of the storage plate 5 is rotatably attached to the connection end 72 of the hinge base 7 via the hinge pin 6. That is, a stopper plate 10 that prevents the storage plate 5 from rotating downward is disposed below the plate-shaped hinge base 7, and is fixed to the fixed rail 9 with the bolt 12 via the nut plate 11.

[0018] The adjacent hinge types of the above configuration are arranged such that the tips of their triangular parts 50 face inward, and the base parts 51 or the extended base parts 52 of the fitting plate 5 are arranged on the fixed rail 9 in a zigzag manner without gaps for the required length over the entire length of the slit-shaped opening 4 in the device 2 via the hinge base parts 7. Therefore, this configuration keeps the slit-shaped opening 4 normally closed (Fig. 1, Fig. 5 to Fig. 7). 1 and 2, as the attachment 8 attached to the transport hanger 2 or transport jig 3 abuts against the retaining plate 5 in the traveling direction K by the power of the transport conveyor 1, the retaining plate 5 is gradually lifted and opened. Then, after the attachment 8 has passed, the hinge-type retaining plate 5 closes by its own weight, and the open state of the slit-shaped opening 4 is kept to a minimum (FIG. 5B).

[0019] The functional action of the above-mentioned slit door panel will now be described. (1) When the transport conveyor 1 is operated and the transport hanger 3A or the transport jig 3B starts moving in the travel direction K, the secondary hanger 15 (transport hanger 3A) that suspends the workpiece W and the attachment 8 attached to the transport jig 3B itself move at the same time. (2) At that time, the attachment 8 flips up the storage plates 5 one by one, allowing the transport hanger 3A or the transport jig 3B to pass through. (3) The retaining plate 5 covers the gap P of the slit-shaped opening 4 except for the portion where the attachment 8 is lifted up, so that it is possible to minimize the diffusion of air, mist, steam, debris, etc. from inside or outside the painting equipment auxiliary device 2. (4) Since the attachment 8 has a conical shape, even if the transport hanger 3A or the transport jig 3B rotates, the attachment 8 can be kept in constant contact with the transport direction K. The same effect can be obtained even if the transport conveyor 1 rotates in the reverse direction. (5) After the transport hanger 3A or the transport jig 3B has passed, the retaining plate 5 returns due to its own weight, thereby closing the gap at the slit opening 4.

[0020] Although the embodiments have been described above based on the drawings, it should be noted that the present invention is not limited to the illustrated examples, and includes the range of design modifications and application variations that would normally be made by a person skilled in the art, provided that the scope does not deviate from the technical concept of the present invention.
