Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the painting process and the drying process are performed on the assembled automobile body, in the final assembly process of the automobile body, it is necessary to disassemble the assembled automobile body for painting once, and in finally assembling and manufacturing the automobile body, extra man-hours (disassembly process) have occurred.

[0005] Therefore, an object of the present invention is to obtain a conveyance system and a conveyance method for automobile body parts that can reduce extra man-hours and efficiently manufacture an automobile body.

Means for Solving the Problems

[0006] To achieve the above objective, the automobile body parts transport system according to the present invention comprises: a frame-shaped hanger member to which automobile body parts are attached; a first transport mechanism for suspending and transporting the hanger member to which the body parts are attached in order to perform a first process on the body parts; and a second transport mechanism for transporting the hanger member to which the body parts are attached on a conveyor in order to perform a second process on the body parts.

[0007] Furthermore, the method for transporting automobile body parts according to the present invention includes a setting step of attaching automobile body parts to a frame-shaped hanger member, a first transport step of performing a first process on the body parts while transporting the hanger member suspended from it, and a second transport step of performing a second process on the body parts while transporting the hanger member on a conveyor.

[0008] According to the present invention, in the setting process, the body parts of an automobile are attached to a frame-shaped hanger member. Then, in the first transport process, the hanger member is suspended and transported while the body parts attached to the hanger member are subjected to a first process. Furthermore, in the second transport process, the hanger member is transported by a conveyor while the body parts attached to the hanger member are subjected to a second process.

[0009] In other words, the present invention processes the automobile body parts while transporting them, rather than processing the assembled automobile body while transporting it. Therefore, in the final assembly process of the automobile body, it is not necessary to disassemble the assembled automobile body, and no extra steps (disassembly process) are incurred in the final assembly and manufacturing of the automobile body. Thus, according to the present invention, extra steps are reduced, and automobile bodies are manufactured efficiently. [Effects of the Invention]

[0010] As described above, according to the present invention, unnecessary man-hours can be reduced, and automobile bodies can be manufactured efficiently. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. For convenience of explanation, the arrow FR appropriately shown in each figure is taken as the front direction of the hanger member and the conveyance direction of the hanger member. And the arrow UP is taken as the upward direction of the hanger member, and the arrow RH is taken as the rightward direction of the hanger member.

[0013] <First Embodiment> First, the first embodiment will be described. As shown in FIG. 1, the conveyance method of the body parts 12 of the automobile 10 according to the first embodiment does not perform the process while conveying the assembled body of the automobile 10, but performs the process while conveying the body parts 12 of the automobile 10 on a sub-line, and performs the assembly on the main line when manufacturing the automobile 10. Therefore, in the conveyance method according to the first embodiment, on the sub-line, the body parts 12 of the automobile 10 are attached to the hanger member 20 (see FIGS. 2 to 8), and the process is performed while conveying the hanger member 20.

[0014] As shown in FIG. 2, the hanger member 20 constituting the conveyance system of the body parts 12 of the automobile 10 according to the first embodiment is formed in a substantially rectangular frame shape in which the longitudinal direction is the front-rear direction when viewed from the left-right direction, and two are provided side by side at a minimum pitch in the left-right direction. The body parts 12 of one automobile 10 are divided and attached to these two hanger members 20.

[0015] To give a specific example, the left (one) hanger member 20 is fitted with a trunk lid 14 as a body part 12 and a side member outer panel 18R including the right side door 17R, while the right (other) hanger member 20 is fitted with a bonnet 16 as a body part 12 and a side member outer panel 18L including the left side door 17L. In the following, the sides of the two hanger members 20 that are opposite each other will be referred to as the left-right inner side, and the opposite side will be referred to as the left-right outer side. Furthermore, when the distinction between left and right is not made in the explanation, the letters "L" and "R" representing left and right will be omitted.

[0016] As shown in Figures 2 to 4, each hanger member 20 has an upper frame 22 and a lower frame 24 with a substantially rectangular cross-section that extend in the front-rear direction, and a front frame 26 and a rear frame 28 with a substantially rectangular cross-section that extend in the vertical direction. That is, the front frame 26 is installed on the front ends of the upper frame 22 and the lower frame 24, and the rear frame 28 is installed on the rear ends of the upper frame 22 and the lower frame 24.

[0017] Furthermore, the front and rear ends of the lower frame 24 are provided with a front leg portion 24A and a rear leg portion 24B, respectively, which extend inward in the left-right direction and have a roughly rectangular cross-section. The left-right inner ends of the front leg portion 24A and the left-right inner ends of the rear leg portion 24B are integrally connected by a connecting frame 29, which extends in the front-rear direction and has a roughly rectangular cross-section. In other words, each hanger member 20 is formed in a roughly "L" shape when viewed from the front-rear direction, except for the locking portion 21 which will be described later.

[0018] A pair of front and rear locking portions 21 are provided at predetermined positions in the front-rear direction of the upper frame 22, extending inward in the left-right direction. Locking claws 21A, which are roughly inverted "L" shapes when viewed from the front-rear direction, are integrally provided at the left-right inner ends of the locking portions 21, extending upward. In addition, a plurality of beam portions 23 with a roughly rectangular cross-section, extending in the vertical direction, are installed between the upper frame 22 and the lower frame 24 at predetermined intervals in the front-rear direction.

[0019] As shown in Figure 4, a pair of upper and lower jigs 25 extending inward in the left-right direction are provided protruding from predetermined positions in the vertical direction of each beam section 23. Each jig 25 is formed, for example, with a roughly rectangular cross-section, and each body part 12, such as the trunk lid 14, bonnet 16, side door 17, and side member outer panel 18, is attached to the jig 25 corresponding to its respective mounting position by hooks or the like (not shown).

[0020] As shown in Figure 7, the angle of each body part 12 can be adjusted by changing the length of the upper jig 25A and the lower jig 25B (making the lower jig 25B longer than the upper jig 25A). In addition, the hinges of the hood 16 and side doors 17 can also be used to attach the jig 25.

[0021] As shown in Figures 3 and 4, in the first transport process, the hanger member 20 is transported while suspended by a first transport mechanism 30 which constitutes the transport system according to the first embodiment. The first transport mechanism 30 includes a locking member 32 that locks the locking claws 21A of the hanger member 20 from below, a support member 34 that rotatably supports each locking member 32, a suspension member 36 that supports the support member 34 in a suspended state, and a rail member 38 that transports the suspension member 36 in the transport direction.

[0022] Each locking member 32 has a pair of front and rear arm portions 32A that extend in the vertical direction, and the lower end of each arm portion 32A is a locking claw 32B that extends inward in the left and right direction. The upper end of each arm portion 32A is supported so as to be rotatable in the front and rear direction as an axial direction, and the locking claw 32B at its lower end hooks onto the locking claw 21A from below to hold the hanger member 20.

[0023] The support member 34 has a flat plate portion 34A that is substantially rectangular in plan view with its longitudinal direction in the front-rear direction, and the upper end of the arm portion 32A is rotatably supported at the front and rear ends of the flat plate portion 34A. In addition, a support column 34B extending in the vertical direction is integrally provided protruding from the left-right center of the front and rear ends of the flat plate portion 34A, and the upper end of the support column 34B is integrally joined to the lower surface of the support portion 34C that extends in the front-rear direction.

[0024] The suspension member 36 extends in the front-rear direction and holds the support portion 34C of the support member 34 in a lifted state. The suspension member 36 is supported by the rail member 38 so as to be movable in the transport direction. As a result, the hanger member 20 is transported while suspended by the rail member 38 in the transport direction, and the first processes, namely the pre-treatment for electrodeposition and the electrodeposition coating process, are carried out in conjunction with this transport (see Figure 12).

[0025] Furthermore, as shown in Figure 6, in the second transport process, the hanger member 20 is transported by a second transport mechanism 40 which constitutes the transport system according to the first embodiment. The second transport mechanism 40 has a skid conveyor 42 as an example of a conveyor on which the hanger member 20 is placed, and the skid conveyor 42 extends in the transport direction at a predetermined position with a predetermined distance from the first transport mechanism 30 in the left-right direction (see Figure 9).

[0026] The skid conveyor 42 is equipped with a holder 44 (schematically shown in Figures 10 and 11) that is configured to move in the conveying direction, and the lower frame 24 and connecting frame 29 of the hanger member 20 are held by the holder 44. In other words, the hanger member 20 is conveyed in the conveying direction by the skid conveyor 42 with its lower frame 24 and connecting frame 29 held by the holder 44.

[0027] As shown in Figure 9, the transfer of the hanger members 20 from the first transport mechanism 30 to the second transport mechanism 40 is performed by a robot arm 46 acting as a reversing mechanism. Specifically, the robot arm 46 reverses the left hanger member 20 so that it is positioned on the left side of the skid conveyor 42, and reverses the right hanger member 20 so that it is positioned on the right side of the skid conveyor 42.

[0028] Thus, when transferring the hanger member 20 from the first transport mechanism 30 to the second transport mechanism 40, the robot arm 46 can be used to flip the hanger member 20 over before transfer. Furthermore, even during transport on the skid conveyor 42, the hanger member 20 can be flipped over again by another flipping mechanism, which is a robot arm (not shown).

[0029] In other words, the hanger members 20 transported by the second transport mechanism 40 are transported in an inverted state (with the outer surface facing outward in the left-right direction), as shown in Figures 5 and 6. This configuration allows for efficient sealing processes, etc., to be performed on the outer surface of each body part 12. Furthermore, by being inverted again by the aforementioned robot arm, the sealing processes, etc., can be efficiently performed on the inner surface of each body part 12, as shown in Figure 8.

[0030] As shown in Figure 6, the hanger member 20, which is placed on the skid conveyor 42 by the robot arm 46, is transported on the skid conveyor 42 while undergoing a second process: electrodeposition drying, sealing, and sealing drying (see Figures 10 to 12).

[0031] The hanger member 20 is then transferred from the second transport mechanism 40 to a third transport mechanism (not shown), where it is transported and subjected to a third process: topcoat painting and topcoat drying (see Figure 12). The third transport mechanism transports the hanger member 20 by suspending it, similar to the first transport mechanism 30.

[0032] Furthermore, as shown in Figure 10, the sealing process is performed by a robotic arm 48 (see also Figure 9, where only one side is shown), and the topcoat painting process is also performed by a robotic arm (not shown). Also, as shown in Figure 11, the sealing drying process is performed by infrared radiation emitted from an infrared lamp 52 attached to the tip of a robotic arm 50, and the topcoat drying process is also performed by infrared radiation or the like.

[0033] Furthermore, at least the robot arm 50 used in the sealing drying process is configured to move in the transport direction in accordance with the transport of the hanger member 20. Specifically, a traveling device 54 equipped with a motor and wheels (not shown) is integrally provided at the lower part of the robot arm 50, and this traveling device 54 is capable of traveling in accordance with the transport of the hanger member 20.

[0034] In this first embodiment, it can also be considered as a "painting system" rather than a "transport system." That is, in the painting system according to the first embodiment, while each body part 12 is transported by the hanger member 20, the following processes are carried out: a first process of electrodeposition pretreatment and electrodeposition painting, a second process of electrodeposition drying, sealing and sealing drying, and a third process of topcoat painting and topcoat drying.

[0035] In the conveying system according to the first embodiment, which includes a hanger member 20, a first conveying mechanism 30, a second conveying mechanism 40, a third conveying mechanism (not shown), etc., configured as described above, its operation (conveying method) will now be explained.

[0036] First, in the assembly process, the body parts 12 of the automobile 10 are attached to a frame-shaped hanger member 20. At this time, the body parts 12 of one automobile 10 are attached to two hanger members 20. Therefore, compared to the case where the body parts 12 of one automobile 10 are attached to three or more hanger members, the process can be carried out more efficiently.

[0037] Furthermore, the length of the jig 25 protruding from the hanger member 20 is changed as needed to adjust the angle of the body part 12. This allows for more appropriate and efficient processing of the body part 12 when attaching it to the hanger member 20 compared to when the angle of the body part 12 is not adjustable. In addition, angle adjustment can be easily performed as it only requires changing the length of the jig 25.

[0038] In the assembly process, once the body parts 12 are attached to the hanger members 20, in the first transport process, the hanger members 20 are suspended and transported by the first transport mechanism 30, while the body parts 12 attached to the hanger members 20 are subjected to the first process. That is, pre-treatment is performed in the pre-treatment process shown in Figure 12, and the electrodeposition coating process is performed in the electrodeposition coating process.

[0039] In the first transport process, the hanger member 20 is transported while suspended by the first transport mechanism 30, enabling transport suitable for electrodeposition pretreatment and electrodeposition coating, and allowing for efficient processing of the body part 12.

[0040] Once the electrodeposition coating process is complete, the hanger member 20 is grasped by the robot arm 46 and transferred to the second transport mechanism 40. At this time, the hanger member 20 may be flipped over, or in the second transport process, when the processing on one side of the body part 12 is completed, the hanger member 20 may be flipped over by another robot arm (flipping process).

[0041] Thus, if the hanger member 20 can be flipped over (at least if there is a flipping step between the first transport step and the second transport step in which the hanger member 20 is flipped over), the front and back surfaces of the body part 12 can be processed more efficiently compared to the case where the hanger member 20 cannot be flipped over.

[0042] In the second transport process, the hanger member 20 is transported by the skid conveyor 42 of the second transport mechanism 40, while the body part 12 attached to the hanger member 20 is subjected to the second process. Specifically, electrodeposition drying is performed in the electrodeposition drying process shown in Figure 12, sealing is performed in the sealing process, and sealing drying is performed in the sealing drying process.

[0043] Thus, in the second transport process, the hanger members 20 are transported by the skid conveyor 42 of the second transport mechanism 40, enabling transport suitable for electrodeposition drying, sealing, and sealing drying, and allowing for efficient processing of the body parts 12.

[0044] Furthermore, in the second transport process, the hanger member 20 is held by a holder 44 provided on the skid conveyor 42. Therefore, compared to the case where the hanger member 20 is not held by the holder 44 provided on the skid conveyor 42, the hanger member 20 can be transported with greater precision, and the body parts 12 can be processed more efficiently.

[0045] Furthermore, at least during the sealing and drying process, the sealing and drying treatment is performed by infrared radiation emitted from an infrared lamp 52 attached to the tip of a robot arm 50 that moves in accordance with the transport of the hanger member 20. Therefore, the sealing and drying treatment can be appropriately performed according to the transport speed of the hanger member 20.

[0046] In the third transport process, the hanger member 20 is transported by the third transport mechanism, and the body part 12 attached to the hanger member 20 is subjected to the third process. Specifically, the topcoat painting process is performed in the topcoat painting process shown in Figure 12, and the topcoat drying process is performed in the topcoat drying process.

[0047] Thus, once processing of the body parts 12 is completed while they are held by the hanger members 20, the body parts 12 are removed from the hanger members 20 and stored in designated storage locations, as shown in Figure 15 (see "Various Parts Storage"). Then, when a separate production (manufacturing) instruction is received, each body part 12 is taken out of storage (see "Module Production") and assembled on the main line shown in Figure 1 (see "Assembly") to manufacture the body of the automobile 10.

[0048] Thus, in the first embodiment, processing is performed while transporting the body parts 12 of the automobile 10, rather than while transporting the assembled body of the automobile 10. Therefore, in the final assembly process of the automobile 10 body, there is no need to disassemble the automobile 10 body, which has been assembled for processing such as painting, as in the conventional method. This prevents the occurrence of unnecessary steps (disassembly steps) in the final assembly and manufacturing of the automobile 10 body. In other words, these unnecessary steps (disassembly steps) can be reduced, and the automobile 10 body can be manufactured efficiently.

[0049] Furthermore, since the processing is performed while transporting the body parts 12 of the automobile 10, rather than while transporting the assembled automobile body 10, it is not necessary to have a large width in the left-right direction for the two hanger members 20 arranged side by side in each sub-line shown in Figure 1. It is sufficient to secure the minimum width required for each process. Therefore, it is possible to minimize the site area of ​​the facility (factory) for manufacturing the automobile 10, thereby reducing initial costs and running costs.

[0050] <Second Embodiment> Next, a second embodiment will be described. Note that detailed explanations of configurations and operations common to the first embodiment will be omitted as appropriate.

[0051] In this second embodiment of the transport system and transport method for the body parts 12 of the automobile 10, as shown in Figure 13, the third transport step differs from the first embodiment in that a third process, consisting of film decoration and trimming, is performed. As shown in Figure 14, in the third transport step, a transport pallet 58 having a dedicated jig 56 to which each of the body parts 12 is attached is transported by a third transport mechanism 60 that constitutes the transport system according to the second embodiment.

[0052] The third transport mechanism 60 includes a pair of left and right slat conveyors 62 as an example of a conveyor, and is configured to transport the left and right side portions 58A of the transport pallet 58, which will be described later. The transport pallet 58 is formed in a roughly rectangular frame shape in plan view, and the left and right ends 56A of a dedicated jig 56 are integrally attached to the upper surfaces of the left and right side portions 58A that extend in the front-rear direction.

[0053] The dedicated jig 56 is formed to match the shape of the body part 12, and Figure 14 shows an example in which the bumper 15, which is the body part 12, is attached to the upper surface of the dedicated jig 56. In other words, the dedicated jig 56 shown in Figure 14 is formed in an arch shape (a roughly semicircular arc that is convex upward when viewed from the transport direction, which is the front-to-back direction) having a predetermined length and width so that the bumper 15 can be held on its upper surface.

[0054] A film supply device (not shown) is located above the slat conveyor 62, enabling the supply of film F to the bumpers 15 (body parts 12) on each dedicated jig 56 (each transport pallet 58) that are sequentially transported by the slat conveyor 62. A suction device (not shown) is also located in a predetermined position, enabling the suction (vacuuming) of air from the space enclosed by the upper surface of the dedicated jig 56 and the film F.

[0055] Furthermore, a robotic arm (not shown) is positioned upstream of the film supply device in the transport direction of the body parts 12 (each transport pallet 58), such as the bumper 15, and is used as a transfer mechanism to remove the body parts 12 from the hanger members 20 and attach them to the respective dedicated jigs 56.

[0056] Furthermore, a robotic arm (not shown) with a cutting device attached to its tip is positioned downstream of the body parts 12 (each transport pallet 58), such as the bumper 15, from the film supply device, so that any excess film F protruding from the body parts 12, such as the bumper 15, is cut and removed.

[0057] In the transport system according to the second embodiment, which includes a transfer mechanism (not shown), a third transport mechanism 60, etc., configured as described above, its operation (transport method) will now be explained.

[0058] First, before the third transport process, similar to the first embodiment described above, the body parts 12 that have undergone processing up to the second stage are removed from the hanger member 20 by a robot arm acting as a transfer mechanism and attached to the upper surface of each dedicated jig 56 (transfer process). Then, in the third transport process, the transport pallet 58, each having a dedicated jig 56 to which the body parts 12 are attached, is transported sequentially by a slat conveyor 62 while the third processing is carried out.

[0059] In other words, in the film decoration process, a film decoration process is performed in which the film F is attached in a tightly adhering state to the body parts 12 mounted on the upper surface of each dedicated jig 56. Subsequently, in the trimming process, a trimming process is performed in which any excess film F that extends beyond the body parts 12 is cut and removed.

[0060] Once processing of the body parts 12 is complete, as shown in Figure 15, the body parts 12 are removed from the dedicated jig 56 and stored in designated storage locations for each body part 12 (see "Various Parts Storage"). Then, when a separate production (manufacturing) instruction is received, each body part 12 is taken out of storage (see "Module Production") and assembled on the main line shown in Figure 1 (see "Assembly") to manufacture the body of the automobile 10.

[0061] Thus, in the second embodiment as well, the processing is performed while transporting the body parts 12 of the automobile 10, rather than while transporting the assembled body of the automobile 10. Therefore, the same effects and advantages as in the first embodiment can be obtained in this second embodiment as well. The film decoration process (film decoration processing) and trimming process (trimming processing) according to the second embodiment can also be considered as a "decoration system".

[0062] The transport system and transport method for the body parts 12 of the automobile 10 according to this embodiment have been described above based on the drawings. However, the transport system and transport method for the body parts 12 of the automobile 10 according to this embodiment are not limited to those shown, and can be modified as appropriate without departing from the spirit of the present invention.

[0063] For example, in the hanger member 20, the number and position (spacing) of the beam sections 23 are not limited to those shown in the figure. Also, in the second transport process, the travel speed of the robot arm 50 is controlled according to the transport speed, but this can be addressed by increasing the number of robot arms 50.

[0064] Furthermore, although the above embodiment describes a configuration in which two hanger members 20 are transported in two rows, left and right, it is not limited to this configuration, and they may also be transported in a single row, front and back. Also, in the second transport step, if the hanger members 20 are transported in a single row and robot arms 48 and 50 can be installed on both the left and right sides of the skid conveyor 42, it is not necessary to invert the hanger members 20.

[0065] Furthermore, the third conveying mechanism 60 in the second embodiment is not limited to being composed of a slat conveyor 62. The conveyor system may be of the pallet type, overhead type, or floor type, and may also incorporate a method for changing direction or a lifting function.

[0066] Although not shown in the diagram, the third transport mechanism 60 may also be, for example, a system in which the transport pallet 58 is placed on a trolley and the trolley is transported by an automated guided vehicle (AGV), a system in which it is towed by a towing vehicle, or a system in which the transport pallet 58 is transported suspended by an overhead conveyor. Alternatively, the hanger member 20 may be transported by a slat conveyor 62 without removing the body parts 12 from the hanger member 20. [Explanation of Symbols]
