Description

Technical Field

[0001] The present invention relates to a panel posture changing device and a posture changing method.

Background Art

[0002] Relatively wide surface materials (panels) such as outer wall panels, frame materials such as sashes, and window glass often require posture changes such as changing the posture of the panel from a lying posture to an inverted posture or inverting the panel at the manufacturing stage. As a primitive method for changing the posture of a panel, there is a method in which one or two workers manually change the posture of the panel. However, for manually changing the posture of a panel, there is a limit to the range in which the posture can be changed from the viewpoints of the planar scale and weight of the panel. Therefore, when it is impossible to change the posture of the panel manually, a method of using a device or equipment to change the posture of the panel is applied.

[0003] As an example of such a posture changing device, there is a form in which a cylindrical rotating machine having an inner space capable of accommodating a panel is rotatably installed with respect to a pit constructed on the floor surface of a factory. The upper part of the rotating machine protrudes above the pit (on the floor surface). One of both ends of the rotating machine serves as a loading port through which the panel is carried into the inner space, and the other end serves as an unloading port from which the panel is unloaded from the inner space. The loading port and the unloading port are positioned above the pit.

[0004] One end of a loading-side conveyor table for automatically loading the panel communicates with the loading port of the rotating machine, and one end of an unloading-side conveyor table for automatically unloading the panel communicates with the unloading port of the rotating machine. The panel conveyed by the loading-side conveyor table is carried into the inner space of the rotating machine through the loading port. After the rotating machine rotates and, for example, inverts the panel, the panel with the changed posture is conveyed to a predetermined processing plant through the unloading port and via the unloading-side conveyor table.

[0005] As described above, the panel attitude change device in a factory is generally large-scale and has a complex structure, making the production, including the construction of a pit, extensive and costly. Further, as in the above-described example, in the case of a device in which a rotating machine is installed in a pit, since it is a facility fixed in terms of layout, there is a problem that it becomes a factor inhibiting layout changes in a factory.

[0006] Here, Patent Document 1 proposes a panel inversion device that stabilizes and easily lifts and inverts an outer wall panel. Specifically, it is an inversion device that lifts and inverts an extruded hollow outer wall panel in which a plurality of hollow holes parallel to the extrusion direction are formed. Suspension tools are respectively suspended at both ends of a telescopic suspension base. The suspension tool has a rotation axis rotatably provided on the suspension tool body. A handle is formed at the base end of this rotation axis, and a protruding piece that bifurcates into two branches and is inserted into the hollow hole is provided at the tip end. Further, a regulating protrusion extending from the rotation axis is locked to the suspension tool body. With this configuration, the rotation range of the rotation axis with respect to the suspension tool body is regulated.

Summary of the Invention

Problems to be Solved by the Invention

[0008] Since the panel inversion device described in Patent Document 1 lifts and inverts an extruded hollow outer wall panel with a hoisting device, it does not become a factor inhibiting layout changes in a factory like a device in which a rotating machine is installed in a pit constructed on the floor surface. However, due to the configuration of lifting and inverting the panel with a hoisting device, it is difficult to solve the problem that the equipment becomes extensive.

[0009] The present invention has been made in view of the above problems, and an object thereof is to provide a panel attitude changing device having a compact device configuration, being movable, and not being an obstacle to changing the layout of a factory, and a panel attitude changing method applying this attitude changing device.

Means for Solving the Problems

[0010] In order to achieve the above object, one aspect of a panel attitude changing device according to the present invention is a pair of guides extending in the vertical direction, a mounting table on which a panel is placed and which is attached to the pair of guides so as to be movable up and down and rotatable, traction means for pulling a wire attached to a part of the mounting table, and when the wire is pulled by the traction means, the mounting table moves up and down along the guide while rotating, so that the mounting table and the panel change their attitudes.

[0011] According to this aspect, the mounting table on which the panel is mounted and fixed is attached to the pair of guides so as to be movable up and down and rotatable, the wire extending from the traction means is fixed to a part of the mounting table, and when the wire is pulled by the traction means, the mounting table moves up and down along the guide while rotating, so that the attitude is changed to a desired attitude. Therefore, the device configuration becomes compact, the manufacturing cost of the device is also low, and further, since the device is movable, there is no risk of becoming an obstacle to changing the layout of the factory.

[0012] Also, basically, two types of operations, i.e., the rotation operation and the lifting operation of the mounting table (and the panel), can be realized by one traction means (power means), so that the attitude change of the panel can be realized by a small power source. Here, examples of the traction means include actuators such as a hoist, a winch, and a motor. Since the traction means such as a hoist has a braking function, the attitude change of the mounting table (and the panel) can be gradually executed while pulling the wire step by step, and the pulling of the wire can be stopped in an emergency.

[0013] Here, regarding "the mounting table moves up and down along the guide while rotating", for example, in the process of the mounting table rising, the mounting table is gradually changed to an inverted posture, and after, for example, it becomes a vertical posture, in the process of the mounting table descending, the mounting table is gradually changed to a lying posture and becomes a posture reversed from the original posture. This kind of movement is taken as an example.

[0014] Also, in another aspect of the panel posture changing device according to the present invention, the mounting table includes at least a pair of horizontal bars and a pair of vertical bars, a plurality of rollers that touch down on the floor surface and rotate when the mounting table changes its posture are attached to one of the horizontal bars, lifting bodies are rotatably attached to the pair of vertical bars respectively, and both of the lifting bodies are slidably mounted on the pair of guides.

[0015] According to this aspect, since the mounting table has a frame structure including a pair of horizontal bars and a pair of vertical bars, the weight of the device including the mounting table can be made as light as possible. Also, since the mounting table is as light as possible in this way, smooth rotation and lifting of the mounting table with respect to the guide can be realized. Further, since the lifting bodies rotatably attached to the pair of vertical bars respectively are slidably mounted on the pair of guides, smooth and stable rotation and lifting of the mounting table with respect to the guide can be realized. Furthermore, since a plurality of rollers are attached to one of the pair of horizontal bars, when the mounting table pulled by the traction means changes its posture and the rollers touch down on the floor surface, and then when the mounting table rotates while moving up and down along the guide, the rotation of the rollers can smoothly move the mounting table on the floor surface, which leads to smooth rotation and lifting of the mounting table.

[0016] Also, another aspect of the panel posture changing device according to the present invention is when the wire is pulled by the traction means, the rollers touch down on the floor surface, and by further pulling the wire, the lifting body moves up along the guide and the mounting table is inverted.

[0017] According to this aspect, by pulling the wire by the pulling means, the mounting table rises while rotating with respect to the pair of guides. At this time, the rollers rotate on the floor surface and the mounting table smoothly changes its posture, so that the mounting table and the panel mounted and fixed thereon can be quickly changed to an inverted posture parallel to the pair of guides. After the mounting table is changed to the inverted posture, by further pulling the mounting table by the pulling means, the mounting table and the panel in the inverted posture can be inverted.

[0018] Also, in another aspect of the panel posture changing device according to the present invention, The lower end of the guide is supported by a pair of support legs that extend in the moving direction of the roller, which is characterized.

[0019] According to this aspect, since the lower end of the guide is supported by a pair of support legs that extend in the moving direction of the roller, it is possible to maintain the stable posture of the pair of guides when the mounting table and the panel are pulled by the pulling means and change their postures.

[0020] Also, one aspect of the panel posture changing method according to the present invention is A pair of guides extending in the vertical direction, A mounting table on which the panel is mounted and is attached to the pair of guides so as to be movable up and down and rotatable, A wire is attached to a part of the mounting table, and a pulling means for pulling the wire, and using the panel posture changing device having the above, The panel is mounted and fixed on the mounting table, and the wire is pulled by the pulling means, and the mounting table is moved up and down along the guide while rotating, thereby changing the posture of the mounting table and the panel, which is characterized.

[0021] According to this aspect, by changing the posture of the panel using a posture changing device having a compact configuration, the posture changing device can be mounted (moved) at various locations in the factory to change the posture of the panel, and the panel can be efficiently changed to a desired posture and various processes can be performed on the panel. [Advantages of the Invention]

[0022] As can be understood from the above description, according to the panel posture changing device and the posture changing method of the present invention, there can be provided a panel posture changing device in which the device configuration is compact and movable and does not become an obstacle to the layout change of the factory, and a panel posture changing method applying this posture changing device.

[0024] Hereinafter, a panel posture changing device and a posture changing method according to an embodiment will be described with reference to the accompanying drawings. In the present specification and the drawings, substantially the same components may be denoted by the same reference numerals, and redundant descriptions may be omitted.

[0025] [Panel Posture Changing Device and Posture Changing Method According to Embodiment] With reference to FIGS. 1 to 3, an example of a panel posture changing device and a posture changing method according to an embodiment will be described. Here, FIG. 1 is a perspective view showing an example of a panel posture changing device according to an embodiment, and is also a view showing an example of a panel posture changing method according to the embodiment. FIGS. 2 and 3 are views showing an example of a panel posture changing method according to the embodiment following FIG. 1 in order.

[0026] The posture changing device 50 of the panel shown in the figure includes a pair of guides 10 extending in the vertical direction (the illustrated example is the vertical direction), a mounting table 30 that is vertically movable in the X3 direction and rotatable in the X2 direction with respect to the pair of guides 10, and a traction means 40 that traction a wire 45 attached to a part of the mounting table 30.

[0027] The mounting table 30 is a table for mounting a panel (not shown) and changing the posture of the panel. It has a width larger than the width of the panel to be mounted. Therefore, the pair of guides 10 are mounted on the floor surface F of the factory with a separation corresponding to the width of the mounting table 30. After the mounting table 30 and the panel are changed to the desired posture, various processes are performed on the panel with the panel mounted on the mounting table 30.

[0028] Here, the panels whose postures are changed by the posture changing device 50 include outer wall panels (outer wall panel frames and members in which outer wall facing materials are attached to the outer wall panel frames), inner wall panels, ceiling panels, outer wall facing materials such as ceramic siding materials, inner wall facing materials such as gypsum boards, floor materials such as particle boards and ALC boards (Autoclaved Light weight Concrete), sashes, glass windows, and various other panels. Also, the planar scales of the panels include panels of various scales such as 1m×2m and 2m×3m.

[0029] The guide 10 is formed of a steel frame such as a section steel and has a guide groove 12 extending in its longitudinal direction. A lifting body 20 rotatably attached to the mounting table 30 is mounted so as to be vertically movable in the X3 direction with respect to the guide groove 12. The lifting body 20 is formed of, for example, rollers, and the rotation axes of the rollers are attached to the mounting table 30.

[0030] Support legs 14 are fixed to the lower ends of the guides 10. The support legs 14 include an upper cross bar 15 to which the lower ends of the guides 10 are directly fixed, two diagonal bars 16 that taper and extend in a direction spreading away from each other from both ends of the upper cross bar 15 toward the floor surface F, and a lower cross bar 17 that houses and integrates the lower ends of the two diagonal bars 16.

[0031] The upper horizontal bar 15, diagonal bar 16, and lower horizontal bar 17 that constitute the support leg 14 are all formed of shaped steel such as channel steel.

[0032] As shown from FIG. 2 to FIG. 3, the two diagonal bars 16 spread in a tapered shape along the moving direction (X5 direction in FIG. 3) of the two rollers 35 that constitute the mounting table 30 moving on the floor surface F. Since the guide 10 is supported by the support leg 14 including the two diagonal bars 16, it becomes possible to maintain the stable postures of the pair of guides 10 that support the rotating mounting table 30 on its left and right.

[0033] The mounting table 30 is a frame member having a pair of vertical bars 31, a pair of horizontal bars 32 that connect the ends of the pair of vertical bars 31 to each other, and a plurality of intermediate bars 33 that connect the middle of the pair of vertical bars 31 at predetermined intervals. The vertical bars 31, horizontal bars 32, and intermediate bars 33 are also formed of shaped steel such as channel steel.

[0034] Of the pair of horizontal bars 32, two rollers 35 are attached near both ends of the horizontal bar 32 on the side close to the floor surface F when rotated. Incidentally, a plurality of rollers 35 may be provided on both of the pair of horizontal bars 32.

[0035] Also, as shown in FIG. 1, a hook 37 is provided, for example, at the center position of the horizontal bar 32 to which the two rollers 35 are attached, and a wire 45 extending from the traction means 40 is hooked on the hook 37. In the illustrated example, the wire 45 is attached in such a form that the wire 45 extending from the traction means 40 is hooked on the hook 37 and returns to the traction means 40, but one end of the wire 45 may be hooked on the hook 37.

[0036] As shown in FIG. 2, when the traction means 40 is operated to traction the wire 45 in the X1 direction, the mounting table 30 rotates in the X4 direction with respect to the pair of guides 10, and the two rollers 35 land on the floor surface F. When the traction of the wire 45 by the traction means 40 is continued, as shown in FIG. 3, the mounting table 30 is further rotated in the X4 direction, and the rollers 35 move in the X5 direction while rotating on the floor surface F.

[0037] In the process where the two rollers 35 move on the floor surface F in response to the rotation of the mounting table 30, the two elevating bodies 20 rotatably attached to the mounting table 30 rise in the X6 direction along the guide grooves 12 of the corresponding guides 10, and the mounting table 30 and the panel gradually turn upside down as the elevating bodies 20 rise.

[0038] When the elevating body 20 further rises from the state shown in FIG. 3, the mounting table 30 is changed to a vertical posture. The posture of the mounting table 30 is maintained in a desired posture change state while the mounting table 30 is in this vertical posture, and various processes may be performed on the panel, or the panel in the vertical posture may be processed.

[0039] By operating the traction means 40 to further traction the wire 45 with respect to the mounting table 30 in the vertical posture, the mounting table 30 (and the panel fixedly mounted thereon) can also be reversed from the lying posture shown in the original FIG. 1.

[0040] Here, the traction means 40 in the illustrated example is a hoist, and since it has a braking function, the posture change of the mounting table 30 and the panel can be gradually executed while tractioning the wire 45 step by step, and the traction of the wire 45 can be stopped in an emergency. Incidentally, the traction means 40 may be an actuator such as a motor, and preferably has a braking function similar to that of a hoist.

[0041] Since the mounting table 30 on which the panel is fixedly mounted and rotated with respect to the pair of guides 10 is formed of a frame material as in the illustrated example, while having the rigidity to mount the panel, the weight of the mounting table 30 can be made as light as possible, and the overall weight of the posture changing device 50 can be reduced.

[0042] As is clear from FIG. 1, the posture changing device 50 is a device with a relatively compact configuration and can be freely moved on the factory floor F. Since the posture changing device 50 is lightweight, its mobility is good. Although not shown, the lower horizontal bar 17 constituting the support leg 14 may be provided with a plurality of rollers with stoppers at its lower end. The stopper may be released during movement and engaged when the panel is positioned at a predetermined position on the floor F to change the posture of the panel.

[0043] Further, the posture changing device 50 pulls a part of the mounting table 30 by one traction means 40, so that the lifting body 20 rotatably mounted on the mounting table 30 moves up and down along the guide 10. Since the mounting table 30 that has landed on the floor F performs rotation and lifting simultaneously during the process of moving on the floor F, two types of operations, namely the rotation operation and the lifting operation of the mounting table 30 and the panel, can be realized by one traction means 40 (power means). Therefore, smooth posture change of the panel can be realized with a small number (one) of power sources.

[0044] In addition, other embodiments in which other components are combined with the configurations described in the above embodiments may be possible, and the present invention is not limited to the configurations shown here at all. In this regard, it can be changed without departing from the gist of the present invention and can be appropriately determined according to the application form.
