DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass wool pushing apparatus for pushing glass wool as a heat insulating material into a wooden panel used for a wall panel, a floor panel and the like of a prefabricated house.

[0002]

2. Description of the Related Art In general, as a method of building a prefabricated house, there is a method of assembling a wood panel P such as a wall panel or a floor panel previously manufactured in a factory at a construction site.
As shown in FIG. 2, the wood panel P is formed by assembling the cores 1... In a rectangular frame shape, and further, in the frame shape.
The frame 1 is assembled by assembling the cores 1 so as to form a grid inside
Is formed by filling the inside of the frame 2 with a heat insulating material such as glass wool 4 and attaching the face plates 5 to both sides of the frame 2.

[0003] In recent years, the automation of the manufacture of such a wood panel P has been attempted. In the wood panel P manufacturing line, a frame for the core members 1 and a face plate 5 for attaching the face plate 5 to the core members 1. Automation of application of an adhesive, attachment of the face plate 5, and the like are achieved.

[0004]

On the other hand, in a wood panel manufacturing line, when filling a frame with a face plate attached to one face with glass wool from the other face,
Simply placing the glass wool in the frame will cause the glass wool to swell, so it will be a hindrance to apply the adhesive for attaching the face plate to the upper surface of the core, and attach the face plate to the other surface as it is When pasted, there is a possibility that glass wool may be sandwiched between the face plate and the core material, and there is a problem that a human has to push in by hand.

The present invention has been made in view of the above circumstances, and in a wood panel manufacturing line, labor for pushing glass wool into a wood panel can be reduced by automating the task of pushing the glass wool into the wood panel. It is an object to provide a glass wool pushing device.

[0006]

According to the present invention, there is provided a glass wool push-in device, comprising a support base having two columns erected on both left and right sides, and sliding the left and right ends on the two columns up and down, respectively. A support bar freely supported, driving means for moving the support bar up and down, and a plurality of push rods arranged on the support bar along the length direction of the support bar and for pushing glass wool inside the frame body And conveying means for passing the frame in a state where the glass wool is placed below the support bar, wherein the support bar is provided with a through hole vertically penetrating at a position where the pushing rod is provided. The push rod includes a rod-shaped rod portion thinner than the through hole and a hook portion provided at an upper end portion of the rod portion and having a larger thickness than the through hole, and the push rod is inserted into the through hole of the support bar. Part is inserted from above, the pushing rod is vertically hung on the support bar by the hook part, and the lower end of the pushing rod is lower than the upper surface of the core of the frame body moving at least below the support bar. The movement to the point is a means for solving the above problem.

[0007]

The glass wool is placed inside the frame, with the frame with the face plate attached on one side and the face plate facing down. And it is made to pass under the support bar by the conveying means. Then, the support bar is moved up and down when the frame passes. When the lower end of the pushing rod strikes the glass wool from above, the glass wool is pushed into the inside of the frame, and the height of the upper surface of the glass wool becomes lower than the height of the core material.

At this time, since the pushing rod is not fixed to the support bar but is hung up and down freely, the glass wool is pushed by the inertial force and weight of the pushing rod moving from top to bottom. Would be. Also, even if the position of the push rod overlaps with the position of the core of the frame, even if the support bar further descends when the tip of the push rod comes into contact with the core, the support bar can move up and down freely. The pushed-in rod which has just been hooked does not further press the core material and attempt to descend.
