Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a panel core material for forming a core material frame of a panel used for walls, floors, etc. of prefabricated houses at right angles and pressing and shaping it into a predetermined rectangular frame shape. The press device for a frame can be used for pressing and shaping a core material frame in a panel for a house of any size.

[Background Art and its Problems] Generally, in a panel for a house, a core material is framed in a rectangular shape, and a casket is vertically and horizontally passed inside the frame, if necessary.
Appropriate face materials are adhered to the front and back surfaces of the core frame. At this time, the core material frame of the panel needs to be formed into an accurate quadrangle by accurately projecting the corners thereof. However, in order to project the core material frame at a right angle, an L-shaped ruler has conventionally been used. The material frame is pressed manually or by using a simple jig, and in this pressed state, each corner of the core material frame is nailed.

However, in the case of using such an L-shaped ruler to press and shape with a hand etc., not only the work efficiency is poor, but when the panel is placed on the line and continuously manufactured, There is a problem in that this pressing step becomes offline, which impairs continuity of manufacturing and significantly impairs work efficiency. Further, there is a demand for a device capable of presetting the pressing means according to each panel size without increasing the pressing stroke in the pressing step so much even when the panels having different sizes are flown.

[Object of the Invention] An object of the present invention is to significantly expand the size range of the panel core material frame that can be pressure-shaped in the case where panels are continuously manufactured, and also to press-shape the panel core material frame. An object of the present invention is to provide a panel core material frame pressing device capable of efficiently and continuously performing.

[Means and Actions for Solving Problems]

The present invention is a panel core material frame pressing device that presses the panel core material frame while loading and unloading the panel core material frame that is temporarily assembled in advance in a square frame shape and transported in one direction. A frame having parallel rollers, and a panel core material frame that is carried in at the time of the protrusion at the exit side of the transport path of the panel core material frame carried on the rollers of this frame A stopper for stopping the movement of the panel in the carrying-in direction, and a stopper provided on the entrance side of the transport path with respect to the stopper and capable of changing the relative position of the stopper along the transport direction of the panel core material, and the panel. Pressing means for pressing up and down the panel core material frame carried on the roller when the core material frame is moved down on the conveying path and moving down, and the pressing means. A pressing means driving mechanism for changing the relative position to the stopper of the step, and a fixed ruler which is arranged along the transport direction of the panel core material frame and serves as a reference of the panel core material frame in a direction orthogonal to the transport direction. A moving ruler provided so as to press the panel core material frame toward the fixed ruler and change the position of the panel core material frame with respect to the fixed ruler in the direction orthogonal to the transport direction, and the fixed ruler of the movable ruler. And a moving ruler drive means for changing the position with respect to, and a movable stand formed in the pressing means drive mechanism separately from the frame and formed in a gate shape crossing the frame, and in the transport direction of the panel core material frame. Along with guide means provided on the frame,
The pressing means is integrated with the movable base via the elevating means for moving the pressing means up and down, and the movable base is guided by the guiding means so that the movable base can be moved only along the conveying direction of the panel core material frame. It constitutes a press machine.

In such an aspect of the invention, the pressing means is raised to open the lower side of the movable table, and the movable ruler is separated from the fixed ruler by a predetermined dimension, so that the panel core material frame can be carried in only by moving in the horizontal direction. In addition, by immersing the stopper, the panel core material frame can be carried out only by moving in the horizontal direction.

Further, if the pushing means is raised so as not to interfere with the panel core material frame and the moving ruler, the pushing means can be moved to any position on the transport path of the frame.

In addition, a movable stand that integrates the pressing means is formed in the shape of a gate,
In addition, since the movable table can be moved only in the carrying direction of the panel core material frame by being guided by the guide means, the lateral shake of the movable base can be prevented, so that the panel core material frame is irrespective of the movable distance of the pressing means. It is possible to accurately and surely perform the pressure shaping of the.

Therefore, the panel core material frame can be pressed and shaped while being transported, and the size range of the panel core material frame that can be shaped is greatly expanded by increasing the movable distance of the pressing means. Like

Further, since the pressing means capable of moving up and down and the stopper capable of projecting and retracting can be operated at the same time, it is possible to carry in a new panel core material frame and convey the panel core material frame whose press shaping has been completed at the same time. It will be possible.

Furthermore, the pressing means, the stopper, the fixed ruler, and the moving ruler enable the panel core material frame to be pressed from four directions, and the pressing means can reduce the pressing stroke and reduce the panel core material frame by the pressing means drive mechanism. The position in the transport direction can be adjusted, that is, the desired position can be changed,
The moving ruler drive mechanism allows the moving ruler driving mechanism to shorten the pressing stroke and adjust the position with respect to the fixed ruler, that is, the initial position thereof can be changed.

Therefore, in continuously performing the press shaping of the panel core material frame, it becomes possible to move the pressing means and the moving means to the initial positions and start the pressing from each initial position, and the press shaping time is shortened and the panel core is shortened. The efficiency of press shaping of the material frame is improved, and the above-mentioned object is achieved by these.

Further, a pair of nut members 91 attached to a moving frame 90 provided in parallel with the support frame 82 are screwed into the respective feed screw shafts 85, and the nut members 91 are interposed via the nut members 91 as the feed screw shafts 85 rotate. The moving frame 90 is moved in the vertical direction in FIG. 2, that is, in the direction orthogonal to the transport direction of the panel core material frame 20. At this time, bearing bushes 92 are provided in the penetrating portion of the guide shaft 83 of the moving frame 90 so that the moving frame 90 can move in parallel, so that the moving frame 90 can move smoothly along the guide shaft 83. It has become. A pair of moving ruler pressing cylinders 93 are attached to the moving frame 90.
The tip of the piston rod 94 of No. 3 is the support frame 82.
When the movable frame 90 is moved, the support frame 82, and thus the movable ruler 78, are simultaneously moved via the movable ruler pressing cylinder 93. Further, when the piston rod 94 is moved back and forth by driving the pair of moving ruler pressing cylinders 93, the moving ruler 78 can be moved toward and away from the fixed ruler 75. Fixed ruler 75 by moving
The panel core material frame 20 located between the moving ruler 78 and the moving ruler 78 is pressed and shaped in the direction orthogonal to the conveying direction. Here, the moving ruler driving mechanism 80 is constituted by a series of serially numbered members from the connecting member 81 to the piston rod 94.

The initial position can be changed so that it is possible to cope with the change in size of the panel core material frame 20 in the direction orthogonal to the carrying direction.

Next, the operation of this embodiment will be described.

When the panel core material frame 20 is carried in by a carry-in conveyor or the like (not shown) located on the left side of the drawing, the pressing means 60 and the moving ruler 78 are adjusted in advance to the size of the panel core material frame 20.
Set the initial position of. To set the initial position of the pressing means 60, a predetermined command value is given to the motor 52 which is a pulse motor, the feed screw shaft 47 is rotated a predetermined number of times via the gear box 51 and the like, and the feed screw shaft 47 is screwed. The movable base 41 is moved in the conveyance direction of the panel core material frame 20 via the nut 46 to perform. On the other hand, for setting the initial position of the moving ruler 78, a predetermined command value is given to the motor 89, which is also a pulse motor, and the feed screw shaft 85 is rotated a predetermined number of times via the gear box 86 and the like. This is performed by moving the moving frame 90, and thus the moving ruler 78, in a direction orthogonal to the conveying direction via the nut member 91 that is screwed. In addition, the cylinder 3 as a stopper projecting and retracting drive mechanism
3, the stopper 32 is projected into the transport path of the panel core material frame 20, and the hoisting cylinder 62 is operated to reduce the piston rod 63 to raise the hoisting frame 65, and further, the roller drive motor 17 Drive the roller 11
To rotate. In this state, when the panel core material frame 20 is sent from the previous process side and carried onto the roller 11, the panel core material frame 20 is stopped by the rotation of the roller 11.
The panel core material frame 20 is moved toward the side and the stopper 32
When the roller drive motor 17 is brought into contact with the roller drive motor 17, the detection mechanism (not shown) detects this state.

Then, the undulating cylinder 62 of the pressing means 60 is operated,
The undulating frame 65 is moved to the lowered position shown by the solid line in FIG. 1, that is, on the transport path of the panel core material frame 20,
Moreover, the pressing cylinder 66 is driven to drive the piston rod 6
7 is advanced, the pressing plate 71 is advanced via the slider 68 and the bracket 70, and in this pressing plate 71,
The panel core material frame 20 is attached to the stopper 32 by an attachment 72 attached at a position where it does not interfere with the moving ruler 78.
Then, the panel core material frame 20 is pressed and shaped in the transport direction. At this time, if necessary, a one-way clutch or the like is interposed between the roller 11 and the sprocket 12 connected thereto, and each sprocket connected by the main chain 13 when the roller drive motor 17 is stopped. Even when 12 is stopped, each roller 11 is smoothly rotated without giving any resistance to the movement of the panel core material frame 20 to the stopper 32 side, and the panel core material frame 20 is moved to the stopper support frame 30 side. Can be done easily. When the one-way clutch is not used, the panel core material frame 20 slides on the roller 11 and is pressed and moved.

Then, when the moving ruler pressing cylinder 93 is driven and the piston rod 94 is contracted, the moving ruler 78 is moved toward the fixed ruler 75 side to press the panel core material frame 20 toward the fixed ruler 75 side, and The pressure shaping is performed in the direction orthogonal to the transport direction of the material frame 20.

In this way, when the panel core material frame 20 is pressed and shaped in the conveying direction and the direction orthogonal thereto, the panel core material frame 2
Each corner of 0 is nailed or tacked by hand and fixed, and the pressure shaping of the panel core material frame 20 is completed. When the shaping is completed, the driving of the pressing cylinder 66 of the pressing means 60 and the moving ruler pressing cylinder 93 is reversed, the pressing of the panel core material frame 20 is released, and then the cylinder 33 is driven to set the stopper 32 to the panel core. The panel core material frame 20 is put into the material frame 20 from the conveyance path and can be carried out. When the roller drive motor 17 is driven in this state,
The panel core material frame 20 on the roller 11 is moved to the right in the figure and is moved to the unloading conveyor side (not shown), and the unloading of the panel core material frame 20 is completed.

Simultaneously with the start of the unloading of the panel core material frame 20, a new panel core material frame 20 is again loaded onto the roller 11 by the above-mentioned procedure, and the pressure shaping is performed by the same action. Will be shaped.

According to this embodiment as described above, the following effects can be obtained.

That is, the pressing means 60 is provided on the movable base 41 so as to be able to move up and down, and the pressing means 60 is prevented from interfering with the panel core material frame 20 and the moving ruler 78 at the time of rising, so that the pressing means 60 is moved by moving the movable base 41. 60 is frame 1
It can be moved to any position on the 0 transport path.

Further, since the movable base 41 in which the pressing means 60 is integrated is formed in a gate shape and is movable only in the carrying-out direction of the panel core material frame 20 by the guide means 4, the movable base 41 is operated by the operation of the pressing means 60. Does not shake laterally, and the pressing means 6
The panel core material frame 20 can be pressed and shaped accurately and reliably regardless of the movable length of zero.

Therefore, the moving distance of the pressing means 60 can be extended, and the panel core material frame 20 can be pressed and shaped from a short one to a long one in the transport direction, and the size range of the panel core material frame 20 that can be shaped is greatly expanded. it can.

Here, the stopper 32 and the pressing means 60 mechanically shape the unloading direction of the panel core material frame 20, and the fixed ruler 75 and the moving ruler 78 mechanically form the direction orthogonal to the unloading direction. Therefore, the press molding of the panel core material frame 20 can be performed efficiently and accurately. Further, the initial positions of the pressing means 60 and the moving ruler 78 are set in advance by the pressing means driving mechanism 40 and the moving ruler driving mechanism 80, respectively.
Even if the strokes of the pressing cylinder 66 and the moving ruler pressing cylinder 93 are not so large, it is possible to deal with the pressure shaping of the panel core material frames 20 of various sizes. Therefore, since the stroke is short, the pressure shaping time can be shortened. Moreover, since the panel core material frame 20 can be loaded and unloaded at the same time by the protruding and retractable stoppers 32 and the up-and-down pressing means 60, which are respectively provided at the exit and the entrance side of the transport path of the panel core material frame 20, the panel core material frame 20 can be loaded and unloaded simultaneously. The transport time of the material frame 20 can be shortened. By shortening these times, the time required for the pressure shaping work in which the panel core material frame 20 is continuously carried in, pressed, and carried out is shortened, and the efficiency of the pressure shaping work can be improved. Further, the pressing means 60 and the moving ruler 78
Since the pressing means drive mechanism 40 and the moving ruler drive mechanism 80 for changing the position of (1) are respectively provided with the motor 52 and the motor 89 which are pulse motors, the positioning can be accurately performed. Further, in the overall configuration of this embodiment, since the roller 11 and the like are used to perform pressure shaping along the transport direction of the panel core material frame 20, the entire apparatus can be directly incorporated in the panel manufacturing line, and the panel can be integrated. It is extremely useful in setting up the production line.

Although each roller 11 is configured to be driven by the roller drive motor 17 in the above-described embodiment, the roller 11 may be a simple free roller. In this case, the panel core material frame 20 is loaded and unloaded on the roller 11 side. It may be carried out by a fork conveyor or a crane which can be carried in up to the above. However, if the roller 11 can be driven, there is an advantage that it can be easily incorporated into an integrated manufacturing line. Further, the driving source of the pressing means driving mechanism 40 and the moving ruler driving mechanism 80 for driving the pressing means 60 and the moving ruler 78 does not necessarily have to be a pulse motor, and may be a general motor or the like. There is an advantage that the setting can be made accurately and easily. Further, the driving mechanism of the pressing means driving mechanism 40 and the moving ruler driving mechanism 80 is not necessarily limited to the one using the feed screw shaft, but a rack and a pinion are used, and the rack or the pinion is driven and moved. Mechanism may be used. Further, although the stopper support frame 30 is provided separately from the frame 10, the stopper support frame 30 and the frame 10 may be provided integrally, and the fixing ruler 75 is directly fixed to the frame 10. Other configurations such as providing a frame different from the frame 10 and fixing the fixed ruler 75 to this frame may be used. In short, the present invention is not limited to the configuration of the above-mentioned embodiment, and is within a range in which the object of the present invention can be achieved. Modifications such as the structure of are included in the present invention.
