Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outer wall panel finishing transport device that transports the outer wall panel in a standing state in a process of finishing an outer wall panel for a prefab house.
[0002]
[Prior art]
The process for producing a prefabricated house panel is roughly divided into a frame assembling process, a face material attaching process, a panel painting process, a panel finishing process, and a panel alignment packing process.
[0003]
In the panel finishing process, a sash is attached to the outer wall panel, a coking operation is performed on the joint, and the like. Therefore, a conveying device that conveys the outer wall panel in a standing state is required.
[0004]
In the conventional panel transport apparatus, a transport rail is provided at an upper portion along the transport line of the outer wall panel, and a ceiling self-propelled carriage that can travel along the transport rail is provided. The ceiling self-propelled carriage grips and hangs the upper end of the outer wall panel.
[0005]
The above-mentioned ceiling self-propelled carriage is moved to move the outer wall panel to the work place where the finishing work is performed. In the work place, workers work on the work table.
At this time, since the finishing work is performed over the entire outer wall panel surface, a lifter that can be raised and lowered has been used for the work table.
[0006]
[Problems to be solved by the invention]
However, the above-described transfer device has a problem that a lifter that is lifted and lowered by an operator is large and requires an installation space, which is disadvantageous in terms of layout and increases in manufacturing cost.
[0007]
In view of this, it has become increasingly common to adopt a transfer device that does not require a lifter by forming the outer wall panel gripping portion of the ceiling self-propelled carriage so that it can be raised and lowered and raising and lowering the outer wall panel.
[0008]
However, during the finishing operation, the outer wall panel may be pressed. However, since this transport device holds the outer wall panel only at its upper end, the outer wall panel is shaken. Therefore, it is necessary to provide an anti-sway device for the outer wall panel on the ground side, which causes a problem that the device becomes complicated.
[0009]
Further, when the ceiling self-propelled carriage travels, the gripping part must be raised to the original position each time, so the conveyance efficiency is not so good. Furthermore, since a control device that raises and lowers the grip portion is required for each overhead traveling carriage, the manufacturing cost has increased significantly.
[0010]
Therefore, the present invention has been devised to solve the above-mentioned problems, and the object thereof is an outer wall panel that has a simple structure and can prevent shaking of the outer wall panel during finishing work and can improve the conveyance efficiency. The object is to provide a finishing conveying device at low cost.
[0011]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides an outer wall panel finishing transfer device that transfers the outer wall panel in a standing state in a process of finishing the outer wall panel for a prefabricated house. A traveling frame that travels along the transport rail, and a lifting cage that is provided on the traveling frame so as to be movable up and down and supports the outer wall panel.
[0012]
According to the said structure, since the outer wall panel is supported by the raising / lowering cage, the shaking of the outer wall panel at the time of finishing work can be prevented. In addition, since the traveling frame can be traveled regardless of the height of the lifting cage, an improvement in transport efficiency is achieved.
[0013]
A power feeding unit is provided at a predetermined position of the transport rail, and a power receiving unit is provided on the traveling frame to receive power supply in contact with the power feeding unit so as to raise and lower the lifting cage when the traveling frame stops at the predetermined position. Are preferred.
[0014]
Further, it is preferable that a roller conveyor is provided below the traveling frame and the traveling frame travels by driving the roller conveyor.
[0015]
Furthermore, it is preferable to provide the lifting cage provided with upper and lower end detecting devices for detecting the upper and lower ends of the lifting and lowering cage.

The configuration of the traverser 36 for traversing the transport carriage 12 will be described with reference to FIGS. 3 and 4.
[0040]
The traverser 36 according to the present embodiment has a function of fixing the outer wall panel 1 sent from the coating process section to the transport carriage 12 in addition to the function of traversing the transport carriage 12.
[0041]
The traverser 36 includes a traversing frame 37 that traverses in a direction orthogonal to the traveling direction of the transport carriage 12, and a gripping device 38 that grips and lifts the upper frame clamper frame 26 of the transport carriage 12. Yes.
[0042]
The traversing frame 37 is configured to self-run on a guide rail 39 that is disposed orthogonal to the traveling direction of the transport carriage 12. A groove 44 is formed in the floor surface 43 of the finishing process section, and the guide rail 39 is provided at a position lower than the floor surface level.
[0043]
A roller conveyor 41 for running the transport carriage 12 is provided below the traversing frame 37. The roller conveyor 41 is disposed at the same height as the other roller conveyors 11, and can transport the transport carriage 12 horizontally from the roller conveyor 11 onto the roller conveyor 41.
[0044]
The gripping device 38 includes a transverse support frame 45 that is movably provided in the same direction as the guide rail 39, and an elevation frame 46 that is supported by the transverse support frame 45 so as to be movable up and down.
[0045]
The transverse frame 37 is provided with a linear guide 47 that guides the movement of the transverse support frame 45 in parallel with the guide rail 39. The transverse support frame 45 is formed in a rectangular shape, and linear motion guides 47 are provided at the positions of the upper end portion and the lower end portion thereof.
[0046]

[0047]
The lifting frame 46 is provided with a grip portion 55 having a U-shaped cross section for gripping the upper frame clamper frame 26 via an air cylinder 65. The air cylinder 65 is provided in a downward direction. After the lift frame 46 is lowered by driving the motor 51 until the grip portion 55 comes into contact with the upper frame clamper frame 26, the air cylinder 65 is used to move the upper frame clamper frame. 26 is pressed against the outer wall panel 1 with a predetermined pressure.
[0048]
Next, the operation of the outer wall panel finishing transfer device 8 having the above configuration will be described while explaining the operation thereof.
[0049]
First, the outer wall panel 1 sent from the coating process section is received by the panel receiving section 5. At this time, the transport carriage 12 is placed on the roller conveyor 41 of the traverser 36 in advance, and the upper frame clamper frame 26 is held by the holding portion 55.
[0050]
And after moving the outer wall panel 1 into the raising / lowering cage 15 by the fork of a transfer apparatus (not shown), the lower end of the panel holding bracket 31 of the upper frame clamper frame 26 is moved to the raising / lowering frame 46 of the traverser 36, It is lowered until it is positioned above the upper end position of the outer wall panel 1 that has been sent by a predetermined clearance.
[0051]
After the lowering of the elevating frame 46 is finished, the air cylinder 65 is extended to lower the gripping portion 55, and then the rack 29 on the upper frame clamper frame 26 side is meshed with the rack provided on the square pipe 25a, The upper frame clamper frame 26 is fixed at that position. As a result, the outer wall panel 1 is supported and fixed by the spring force of the compression coil spring 35 of the panel pressing bracket 31.
[0052]
At this time, since the grip portion 55 is pressed by the air cylinder, the pressing force can be made constant. That is, since the number of panel pressing brackets 31 that press the outer wall panel 1 varies depending on the width size of the outer wall panel 1, the compression force of the outer wall panel 1 is determined by detecting the contraction length of the compression coil spring 35. Although it cannot be held constant, the pressing force can be easily held constant at a desired value by pressing the air cylinder at a constant pressure.
[0053]
Specifically, when the width size of the outer wall panel 1 is large, the number of panel pressing brackets 31 that act is large, and the amount of compression of the compression coil spring 35 is small, while when the width size of the outer wall panel 1 is small, Although the number of panel pressing brackets 31 that act is small and the amount of compression of the compression coil spring 35 increases, the pressing force of the outer wall panel 1 is the same.
[0054]
Thereafter, the traversing frame 37 is traversed to the transport line of the finishing process section, and the transport cart 12 is sent out by driving the roller conveyor 41 and the roller conveyor 11.
[0055]
The transport carriage 12 that fixedly supports the outer wall panel 1 is moved to the finishing work section 6 and stops at a predetermined position. Then, an operator on the work table 59 moves the lifting cage 15 to a desired height to perform a sash mounting operation on the outer wall panel 1, a coking operation on a joint, or the like.
[0056]
At this time, the raising / lowering of the raising / lowering cage 15 is performed by receiving electric power from the electric power feeding part 10 provided in the upper rail 9 via the electric power receiving part 20 provided in the traveling frame 14 and driving the motor 19.
[0057]
As described above, according to the present invention, the outer wall panel 1 is supported by the elevating cage 15, and the elevating cage 15 can be raised and lowered within the traveling frame 14. Therefore, it is necessary to raise and lower the work table 59 on which an operator rides. There is no. Therefore, the work table does not become large, the installation space is small, which is advantageous in terms of layout and can prevent an increase in manufacturing cost.
[0058]
Further, since the outer wall panel 1 is fixed up and down by the upper frame clamper frame 26 and the support base 30 in the elevating cage 15, it is possible to prevent the outer wall panel from shaking during the finishing operation. Furthermore, since the traveling frame 14 can travel regardless of the height of the lifting cage 15, the conveyance efficiency is improved.
[0059]
Further, according to the present invention, the carriage 12 is caused to travel on the roller conveyors 11 and 41, and the lifting cage 15 is lifted and lowered from the power feeding portion 10 provided on the upper rail 9 to the power receiving portion 20 provided on the traveling frame 14. It is done by receiving power through. Therefore, it is not necessary to provide a self-propelled device, a drive circuit, or a control circuit for each transport cart 12, and the simplification of the transport cart 12 can be achieved, and the manufacturing cost can be greatly reduced as a whole.
[0060]
In addition, by providing the power supply unit 10 and the power reception unit 20 above, dust and the like are not easily collected, and maintenance is facilitated.
[0061]
【The invention's effect】
In short, according to the present invention, since the outer wall panel is supported by the elevating cage, an excellent effect is exhibited that the outer wall panel can be prevented from shaking during the finishing operation. In addition, since the traveling frame can be traveled even when the lifting cage is positioned at the height, an improvement in transport efficiency is achieved.
