Description

  The present invention relates to a work processing apparatus and a work processing system, and for example, relates to a work processing apparatus and a work processing system for performing pretreatment by, for example, immersing an automobile body in various tanks when painting an automobile body. is there.

  When a workpiece such as an automobile body is painted, various pretreatment steps are required. For example, an automobile body that has undergone a vehicle body assembly process undergoes a preliminary cleaning process (degreasing process), a surface adjustment process, a film forming process, an electrodeposition process (undercoating process), a drying process, and the like. Among the steps described above, most of the steps except the drying step are performed by immersing the automobile body in a tank in which a predetermined liquid is stored for a predetermined time.

Conventionally, a slipper dip method is sometimes employed when an automobile body is subjected to such processing steps. In the slipper dip method, the automobile body is continuously transported by a transport conveyor along a plurality of long tanks arranged in a straight line, and immersed in each tank and used for each treatment (for example, patents). Reference 1).
JP-A-11-131293

  However, in the above slipper dip method, since the automobile body is immersed in each tank while being conveyed linearly by a conveyor, the process length is inevitably increased. For this reason, a larger installation space is required, leading to an increase in the size of the equipment.

  Therefore, in the present invention, it is a technical problem to provide a work processing apparatus and a work processing system that can suppress an increase in size of equipment.

  In the following, each means suitable for solving the above-described problems will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A work processing apparatus comprising a plurality of tanks in which liquid is stored and immersing a work in each tank, and performing various processes corresponding to each tank with respect to the work,
A column that is set up substantially vertically;
A plurality of swivel arms provided in the column so as to be rotatable about a first axis in a substantially vertical direction as a central axis and tiltable in a vertical direction about a second axis in a substantially horizontal direction;
Rotation driving means for rotating the swivel arm;
Tilt drive means for tilting the swivel arm;
A holding means that is provided on a tip side of the swivel arm and holds a workpiece;
A work processing apparatus comprising the plurality of tanks arranged in a substantially annular shape around the support column.

  According to the means 1, it is possible to carry out the processing relating to the respective tanks arranged in an annular shape by turning the arm to convey the work. Therefore, for example, it is not necessary to convey the workpiece linearly in a relatively long section as in the slipper dip method, the lengthening of the tank arrangement can be suppressed, and the process length can be shortened. As a result, expansion of installation space and enlargement of equipment can be suppressed.

  In addition, unlike the conventional technique in which a workpiece is transferred at a constant speed by a transfer conveyor or the like and the transfer device or the like does not perform processing related to another workpiece during the immersion period of one workpiece, each swivel arm is moved individually. Thereby, the process regarding a some workpiece | work can be performed in parallel. For example, during the immersion period of one workpiece, various operations such as an immersion operation, a lifting operation, and a liquid sagging operation can be performed on another workpiece. Furthermore, the processing speed of a predetermined work can be increased by individually changing the drive speed of the tilting drive of the swivel arm. As a result, it is possible to increase the workpiece processing speed comprehensively and shorten the workpiece processing time.

Thereby, for example, when transporting a long workpiece in the front-rear direction and immersing it in each tank as in an automobile body, the inclination of the workpiece is changed, and the longitudinal direction of the workpiece is set in a substantially vertical direction. As a result, the workpiece conveyance pitch can be shortened, and the process length can be further shortened and the workpiece processing time can be shortened.

  If the workpiece is immersed in each tank in a state where the longitudinal direction of the workpiece is substantially vertical, the resistance that the workpiece receives from the liquid when the workpiece is immersed is reduced, and the workpiece is distorted by the resistance. Can be prevented from occurring. Further, when the workpiece is lifted, the liquid hardly remains in the workpiece, and the sagging of the liquid is improved. As a result, the liquid replenishment interval in each tank can be extended, and the production cost can be reduced.

  Further, by swinging the workpiece by the holding means, it is possible to further enhance the effect of removing dust and the like adhering to the workpiece described in the means 1 and the effect of improving the sagging of the liquid.

  Furthermore, the workpiece can be immersed in each tank from various directions such as the front side and the rear side of the workpiece, and various treatments can be realized.

Then, the vehicle body 12 is controlled to be tact-conveyed sequentially.

  And the 1st conveyance conveyor 13 is comprised so that the motor vehicle body 12 may be conveyed to the 1st stop position X1, and the turning arms 22a-22h hold | maintain the motor vehicle body 12 in the said 1st stop position X1. ing. That is, the first stop position X1 corresponds to the workpiece holding position in the present embodiment. The first stop position X1 is provided with a turntable (not shown) as changing means for changing the direction of the automobile body 12.

  Further, the second transfer conveyor 14 is configured to transfer the automobile body 12 from the seventh stop position X7 to the next process, and the swing arms 22a to 22h move the automobile body 12 at the seventh stop position X7. It is supposed to be released. That is, the seventh stop position X7 corresponds to the workpiece release position in the present embodiment.

  Furthermore, an empty cart transport mechanism 45 that transports a cart 38 to be described later from the first stop position X1 to the seventh stop position X7 is provided.

  In the present embodiment, the automobile body 12 is transported while being placed and fixed on a skid 35 as a transport member. The main body of the skid 35 has a substantially flat plate shape corresponding to the vertically long shape of the automobile body 12, and a shaft portion 36 extending in the lateral direction is provided at a substantially central portion in the longitudinal direction.

  Then, when being transported by the first transporting conveyor 13 and the second transporting conveyor 14, the automobile body 12 is placed on the carriage 38 in a state of being fixed on the skid 35 and transported along the rail 39. .

  On the other hand, when transported by the main transport device 10, both ends of the shaft portion 36 of the skid 35 are transported while being held by the pair of holding portions 32 of the tilt mechanism 24. Accordingly, both end portions of the shaft portion 36 constitute a pair of held portions in the present embodiment, and a line along the longitudinal direction of the shaft portion 36 becomes the axis Z4, and the skid 35 and the automobile body are centered on the axis Z4. 12 is integrally rotated.

  Next, a plurality of tanks arranged in a substantially annular shape around the main transfer device 10 (supports 20) will be described. In the preliminary cleaning system, a tank is provided corresponding to the stop position of each of the swivel arms 22a to 22h of the main transfer device 10. More specifically, the first tank 41 corresponding to the preliminary water washing process is provided at the second stop position X2, and the second tank 42 corresponding to the degreasing process is provided from the third stop position X3 to the fourth stop position X4. A third tank 43 and a fourth tank 44 corresponding to the re-watering step are provided at the fifth stop position X5 and the sixth stop position X6, respectively.

  The first tank 41, the third tank 43, and the fourth tank 44 store water for cleaning the surface of the automobile body 12 by applying a predetermined water flow. A predetermined solvent is stored in the second tank 42 in order to remove oil and fat from the surface of the automobile body 12 after the assembly process.

  Next, the effect of this Embodiment comprised as mentioned above is demonstrated.

  The car body 12 (including the skid 35) that has been transported to the first stop position X1 by the first transporting conveyor 13 is changed by the turntable so that the direction thereof follows the turning direction of the turning arms 22a to 22h. .

  Subsequently, the swing arms 22 a to 22 h corresponding to the first stop position X 1 tilt downward, and the both ends of the shaft portion 36 of the skid 35 are held by the pair of holding portions 32 of the tilt mechanism 24. Then, the turning arms 22a to 22h tilt upward, and the automobile body 12 is lifted. At the same time, the tilt mechanism 24 rotates the automobile body 12 so that the longitudinal direction of the automobile body 12 is in a substantially vertical direction.

  Next, all the turning arms 22a to 22h turn, and the turning arms 22a to 22h holding the automobile body 12 at the first stop position X1 first stop at the second stop position X2.

  And the said turning arms 22a-22h tilt downward, the motor vehicle body 12 is immersed in the 1st tank 41, and a preliminary water washing process is performed. After a predetermined immersion time has elapsed, the swivel arms 22 a to 22 h tilt upward, and the automobile body 12 is pulled up from the first tank 41.

  Thereafter, the turning arms 22a to 22h are turned intermittently, and the same control as described above is performed at each of the stop positions X3 to X6, and the second tank 42, the third tank 43, and the fourth tank 44 described above. A predetermined process is executed. However, when the automobile body 12 is transported from the third stop position X3 to the fourth stop position X4, the automobile body 12 is immersed in the second tank 42 without being pulled up from the second tank 42. Is maintained.

  Further, in the present embodiment, when each of the above operations is performed, all the swing arms 22a to 22h do not operate in the same manner, but perform operations corresponding to the respective stop positions X1 to X8 individually to perform predetermined operations. I do. For example, after a predetermined automobile body 12 is immersed in the first tank 41, an operation of immersing the automobile body 12 in the predetermined tank with respect to another automobile body 12 at least during the immersion period, the automobile body 12 is pulled up. The work, the liquid sagging work of the raised automobile body 12, etc. are performed.

  Then, the automobile body 12 that has been transported to the seventh stop position X7 is released from the turning arms 22a to 22h at the seventh stop position X7, the direction thereof is changed by the turntable, and the second transport conveyor. 14 is transferred to the next step.

  As described above in detail, the turning arms 22a to 22h are turned, the automobile body 12 is transported, and the processes relating to the tanks 41 to 44 arranged in an annular shape are executed. Therefore, for example, it is not necessary to convey the automobile body linearly in a relatively long section as in the slipper dip method, the lengthening of the tank arrangement can be suppressed, and the process length can be shortened. As a result, expansion of installation space and enlargement of equipment can be suppressed.

  In addition, unlike the conventional technology in which the automobile body is conveyed at a constant speed by a conveyor for transportation, and the conveying device does not perform processing related to the other automobile body during the immersion period of one predetermined automobile body, By individually moving the turning arms 22a to 22h, it is possible to perform processes related to the plurality of automobile bodies 12 in parallel. For example, during the immersion period of one automobile body 12, various operations such as an immersion operation, a pulling operation, and a liquid sagging operation can be performed on the other automobile body 12. Furthermore, the processing speed of the predetermined work can be increased by individually changing the drive speed of the tilting drive of the swing arms 22a to 22h. As a result, the processing speed of the automobile body 12 can be increased overall, and the processing time of the automobile body 12 can be shortened.

  In addition, unlike the prior art in which the transport rails of the transport conveyor are provided on the tank, the transport rails can be omitted, so that dust or the like does not fall from the transport rails and the garbage on the automobile body 12. It is possible to reduce the risk of adhesion. As a result, it is possible to suppress a decrease in coating quality.

  Furthermore, by moving the turning arm in a state where the automobile body 12 is immersed in the tanks 41 to 44 and swinging the automobile body 12, air, dust, or the like attached to the automobile body 12 can be dropped. On the other hand, when the automobile body 12 is swung during the lifting operation of the automobile body 12, the sagging of the liquid is improved.

  Further, by providing the tilt mechanism 24, the automobile body 12 can be rotated at the tip portions of the turning arms 22a to 22h. As a result, when the automobile body 12 is transported or immersed in the tanks 41 to 44, the inclination of the automobile body 12 is changed so that the longitudinal direction of the automobile body 12 is in a substantially vertical direction. Thus, the conveyance pitch of the automobile body 12 can be shortened, and the process length can be further shortened and the processing time can be shortened.

  If the automobile body 12 is immersed in the tanks 41 to 44 in a state where the longitudinal direction of the automobile body 12 is substantially vertical, the resistance that the automobile body 12 receives from the liquid when the automobile body 12 is immersed. And the occurrence of distortion or the like in the automobile body 12 due to the resistance can be suppressed. Further, when the automobile body 12 is pulled up, liquid does not easily remain in the automobile body 12, and the sagging of the liquid is improved. As a result, the liquid replenishment interval in each of the tanks 41 to 44 can be extended, and the production cost can be reduced.

  Further, by swinging the automobile body 12 by the tilt mechanism 24, it is possible to further enhance the effect of removing dust and the like adhering to the automobile body 12 and the effect of improving the sagging of the liquid.

  Furthermore, the automobile body 12 can be immersed in the tanks 41 to 44 from various directions such as the front side and the rear side of the automobile body 12, and various treatments can be realized.

  Further, by fixing and transporting the automobile body 12 to the skid 35, the automobile body 12 can be easily rotated and work can be performed efficiently. As a result, productivity can be improved. Furthermore, it is not necessary to hold the automobile body 12 directly, and it is possible to reduce problems such as damaging the automobile body 12 during transportation.

Therefore, the above system (main transfer device 10 or the like) may be employed as at least one system of various processes such as a surface adjustment process, a film formation process, and an electrodeposition process. Of course, you may employ | adopt in all the processes.
