DETAILED DESCRIPTION OF THE INVENTION The present invention moves a transport frame on which aluminum materials are hung along a track provided along various surface treatment tanks for aluminum materials arranged in a straight line in a fixed order. This invention relates to an operating method for surface treatment that performs various treatments and a surface treatment line used therein.

Conventionally, when performing surface treatment on small items such as plating, as described in Japanese Patent Application Laid-Open No. 100700/1984, treatment equipment is arranged in a loop, and one point in the loop is used as an entrance/exit for the material to be treated into the equipment. The thing had been done. However, when surface treating a large amount of long aluminum materials, etc., the treatment tank becomes large, and the treatment tank is installed either vertically (vertically suspended) or horizontally (horizontally) on the transport frame. Usually, the transport frame is transported and processed by a crane in a direction perpendicular to its longitudinal direction. In this case, it is difficult to arrange the processing tanks in a loop due to the layout of the factory building, so it is normal to arrange the processing tanks in a straight line.In this case, the first end of the processing tanks arranged in a straight line Conventionally, the material to be processed is attached to a transport frame, and the processed material is removed at the end. For example, as shown in FIG. 5, the first treatment tank T ₁ ,
Second treatment tank T ₂ ...Nth treatment tank T _o is continuously arranged in one row in a fixed order, and rails R are laid on both left and right sides of the row of surface treatment tanks, and a traveling crane C is installed on the rail R. Operation in a surface treatment line in which a transport frame F, on which a large number of aluminum profiles m... are suspended, is supported and transported by the crane C in a manner that is freely movable across the treatment tank, and is detachable and movable up and down. As a method, a hanging stand L installed at the starting end of the processing tank row, that is, in front of the first processing tank _T1 ,
A large number of aluminum profiles m are hung on each of a plurality of empty transport frames F by an erecting device D and a stocking device S, and a plurality of cranes C are appropriately carried around the plurality of transport frames F to sequentially transport each processing tank. T ₁ , T ₂ ... _To
Generally, a method is used in which the processed aluminum profile m is suspended from the transport frame that has been processed in each treatment tank using a lifting table L', an overturning device D', and a stocking device S' installed in front _of the T o. There is. However, this conventional operation method requires equipment space at both the start and end ends of the treatment tank row, and also requires a large number of workers because the start and end ends are far apart and cannot perform both tasks. There were drawbacks such as the need for a large number of spare transport frames in order to return empty transport frames to the starting end.

The first invention of the present application provides an operating method that can reduce equipment space and the number of workers in the surface treatment, and the second invention of the present application provides a surface treatment line that can effectively carry out the first invention.

In addition to the object of the first invention, the third invention of the present application provides an operating method that can improve work efficiency compared to the first invention, and the fourth invention of the present application provides an operating method for effectively implementing the third invention. We provide various surface treatment lines that can be used.

Note that the method of hanging aluminum materials on the transport frame in the present invention includes a vertical hanging method in which a large number of aluminum materials are hung vertically on the transport frame, and a hanging jig is vertically attached to both ends of the transport frame. There is a horizontal hanging type in which multiple pieces of aluminum are hung horizontally between both jigs.

The details of the present invention will be explained below with reference to the drawings.

In Figures 1, 2, and 3, there are a first treatment tank T ₁ , a second treatment tank T ₂ , and a third treatment tank T _{3 in the shape of an open-top box necessary for the desired surface treatment of aluminum sections on the floor 1} .

The operation is as follows. Hanging and unhanging stand 10
A large number of aluminum sections 6 are hung, for example, vertically, on the transport frame 7 which is laid down horizontally, and then the transport frame 7 is lifted up by the upright/overturn device 11 and left on standby at the upper part of the stock device 12. . As an example, in the case where the first crane 3 is responsible for the period from the eighth treatment tank _T8 to the terminal treatment tank _To , and the second crane 3' is responsible for the period from the starting end to the eighth treatment tank _T8 , the fourth A method of operating the crane according to the operating program illustrated in the figure will now be described.

(n), (o), (p), and (q) are performed in sequence, and then the first crane 3 is advanced above the processing tank T _o ,
The transfer frame 7 that has completed all processing in the tank T _o is pulled up and retreated onto the relay space 8 for crane delivery when being transferred in a direction other than the processing direction, and there the transfer frame 7 is lowered into the space 8. Then, support it on the receiving blocks 9, 9 (operation (r)). 1st
Crane 3 repeats the operations from (j) to (r) above.

On the other hand, after performing the above-mentioned work (h), the second crane 3' moves forward onto the relay space 8, pulls up the fully processed transport frame 7 housed in the space 8, and returns it to the starting end. The transport frame 7 is lowered to the lower stage of the stock device 12 (operation (i)). The second crane 3' repeats the above operations (a) to (i).

The fully processed transport frame 7 lowered to the lower part of the stocking device 12 is placed horizontally on the hanging/unhanging table 10 by the upright/overturning device 11, and the processed shapes 6 are removed from the transport frame. After that, a new aluminum profile 6 is hung and stored in the upper part of the stocking device 12.

The operation described above follows the operation program shown in Fig. 4, which was appropriately selected using two cranes 3, 3' and one relay space 8, but the number of cranes and relay spaces were further increased. However, various operations can be performed according to other operation programs.

Next, the other operating method of the present application and the surface treatment line used therein are suitable for cases where the number of treatment tanks is small and only one traveling crane is required, and the method is suitable for cases where the number of treatment tanks is small and only one traveling crane is required. An operating method in which aluminum materials are hung from and unsuspended from the transport frame in a hanging and unhanging yard at the starting end or terminal end of the processing tank row, and the starting end or terminal end of the processing tank row is This is a surface treatment line consisting of a hanging and unhanging yard provided at the processing tank, a track arranged along each treatment tank, and a traveling crane mounted on the track. In this case, in order to transport the transport frames sequentially to each processing tank and to avoid hindrance to the movement of the crane that transports the transport frames in a direction other than the processing direction, the transport frames must be moved so that the end of the transport frame is known and the start end of the frame is known, or the beginning of the transport frame is An example in which the terminal end can be transported by a transport device other than the above-mentioned crane (for example, a transport device for moving a transport frame on which the aluminum material is suspended is disposed above the crane) may also be implemented as appropriate.

In each of the embodiments of the invention described above, a hanging and unhanging yard may be provided at the end of the processing tank row.
However, in this case, the transport frame on which the aluminum sections are hung is once returned to the starting end, and then moved from there to each processing tank in a fixed order. Furthermore, in each of the above examples, the method of hanging the aluminum profile to the transport frame includes not only vertical hanging but also horizontal hanging. Note that the hanging and unhanging of aluminum materials from the transport frame is carried out manually on the transport frame supported by the lower part of the stocking device 12 shown in Figs. ,
The suspended transport frame may then be transported to the upper section using a suitable lift device.

According to the operating method for a surface treatment line for aluminum materials according to the first invention of the present application, only the starting end or the terminal end of the treatment tank row is used as a hanging and unhanging yard, and a traveling crane is used to transport the transport frame on which the aluminum materials are suspended. Since it is possible to transport the transport frame to each processing tank and also transport the transport frame in a direction other than the processing direction, the equipment space can be greatly reduced, and
The workers at the yard mentioned above can also handle the work of hanging and unhanging aluminum materials from the transport frame, reducing the number of workers. The processed aluminum material can be directly transferred to the pallet transported to the removal yard and transported to the next process, which has the advantage of eliminating the need to transport empty pallets from the start end to the end, as was the case in the past. When using a rising/falling device for hanging and unhanging operations, one device is sufficient instead of the conventional method of requiring two devices at the start and end ends, and the operations for standing up and falling down are duplicated. This can also contribute to reducing equipment costs and improving efficiency, such as by eliminating

According to the surface treatment line of the second invention of the present application, the operating method of the first invention can be effectively carried out, and the same effects as the first invention can be achieved.

According to the operating method of the third invention of the present application, the same effects as the first invention can be obtained, and only by creating a relay space between arbitrary processing tanks and selecting an operation program for the traveling crane, a special device is used. Efficient surface treatment can be carried out on a large surface treatment line equipped with multiple processing tanks and multiple traveling cranes, and in addition to the conventional method of lifting at the starting end and unhanging at the end, there is no need for a relay space. There is also the advantage that the present invention can be carried out with only slight changes in the operating method for a surface treatment line in which empty transport frames are returned from the terminal end to the starting end using a .

According to the surface treatment line of the fourth invention of the present application, the operating method of the third invention can be effectively carried out, and the same effects as the third invention can be achieved.
