Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gypsum board spacing regulating device in a construction panel forming machine.

Currently, architectural panels are being produced that have plasterboard attached to the inside of a metal plate with connecting bends formed on both sides, but this architectural panel is manufactured using a device for applying adhesive to long metal plates. , a forming roll for bending both sides of a metal plate, a roll for supplying a fixed length of gypsum board inside the metal plate, a pressing roll for pasting the metal plate and the gypsum board, and a fixed length cutting device for the metal plate. It is manufactured by a molding machine that is installed on the transfer line.

However, in this type of molding machine, due to the cutting of metal plates,
There is a certain distance between the plasterboards, but the gap is determined by the worker's eye, making it difficult to work.Also, there is a difference in the width of the gap, which makes it difficult to cut to a standard length. There is a drawback that a large deviation occurs in the distance between the end of the metal plate cut to a length shorter than the predetermined length of the metal plate, and a large number of defective products are produced.

The present invention aims to eliminate these drawbacks and further improve the energy consumption and yield of forming architectural panels.
One embodiment will be described with reference to the drawings. A supply device A for gypsum board 4 is mounted on the upper front side of a roller conveyor 30 that forms a transfer path a for a long metal plate 2 on a machine frame 1.

This supply device A includes a feed roll 5 that rotates at a circumferential speed faster than the feed speed of the metal plate 2, that is, the line speed, and a holding roll 5 that presses the gypsum board 4 against the feed roll 5 and supplies it onto the metal plate 2. Therefore, this holding roll 6 is pivotally supported on the tip of an arm 7 that rotates around a fulcrum P.
The arm 7 is connected to a rod of a cylinder 8 which is its driving mechanism.

Further, in front of the supply device A, a pair of upper and lower press rolls 9, 9 are disposed for pressing and adhering the metal plate 1 and the supplied gypsum board 3 on the upper surface thereof.

A support frame 10 is disposed between the supply device A for the plasterboard 4 and the pressure roll 9°9, and lifting cylinders 11, 11 are vertically disposed at both the front and rear ends of the support frame 10, and a rail with a square cross section is attached to the rod. 12 are connected.

This rail 12 supports a sliding body 13 that moves back and forth within the support frame 10 guided by the rail 12, and the lower end of this sliding body 13 has the rear end of the preceding gypsum board 4 and the following gypsum board. A spacing regulating plate 14 is provided vertically to maintain a constant spacing from the tip of the board 4.

In addition, the sliding body 13 is provided with a backward drive device B disposed above the rail 12, and this backward drive device B connects a chain 16 stretched between a pair of front and rear sprockets 15, 15. A rebound claw 17°17 is provided protrudingly.

The slider 13 is engaged in the rear inner side of the support frame 10, that is, in the retracted position of the slider 13 in the raised state, and is separated in the lowered state with a stopper 18 for preventing forward movement, and a stopper 18 that closes and is supplied when the slider 13 retreats. A limit switch LS1 that sends a command to the cylinder 8 for driving the arm 7 in the device A is disposed, and a limit switch LS1 is provided inside the front part of the support frame 10, that is, at the forward position of the sliding body 13, to prevent the sliding body 13 from moving forward. The cylinders 11, 11 . for raising and lowering the rail 12 are closed by A limit switch LS2 is provided for giving a command to the clutch motor M of the backward drive device B, that is, the motor M directly connected to one sprocket 15.

The reference numeral LS3 is a limit switch for stopping the clutch motor M, which corresponds to the rebound pawls 17, 17, and 19,1
9 is a gypsum board 3 near the limit switch LS2.
These are a pair of front and rear support rollers pressed against each other, and are used to support the end portion of the gypsum board 3 holding the space regulating plate 14 so that it does not lift up when the plate 14 is pulled out.

One embodiment of the present invention has the above-mentioned configuration, so that a gypsum board 4 cut in advance to a certain size is supplied to a long metal plate 2 that runs on a roller conveyor 3 and has an adhesive applied to its upper surface. However, as shown in FIG. 1, the leading end of the next gypsum board 4 is supported by the rear end of the sliding body 130 interval regulating plate 14.

As shown in FIG. 3A, when the rear end of the preceding gypsum board 4 passes the interval regulating plate 14, the sliding body 13 falls onto the metal plate 2, so it engages with the IJ Mitswitch LS and closes it. , actuate the cylinder 8 to rotate the arm 7,
A press roll 6 presses the gypsum board 4 against a feed roll 5 rotating at high speed.

Therefore, the gypsum board 4 starts moving forward at a speed higher than the line speed, causing the sliding body 13 separated from the stopper 18 to instantly reach the preceding gypsum board.

At the same time, the timer goes off and the cylinder 8 returns to its original state, separating the holding roll 6 from the plasterboard 4, so that the plasterboard 4 on the rear side has the same speed as the preceding plasterboard 4. At this time, the sliding body 13 The position shown in Figure 3/\ is reached.

Then, the limit switch LS2 is activated and the lifting cylinder IL11 is activated, so the rail 12 rises and the sliding body 1
3 and the interval regulating plate 14 are pulled up and both plasterboards 4,
40, gaps are formed at regular intervals.

Furthermore, since the clutch motor M of the reverse drive device B operates simultaneously with the operation of the lifting cylinders 11 and 110, the chain 1
6 begins to rotate, and the slider 13 is repelled to the rear side of the rail 12 by the rebound pawl 17 located on the front side, and is supported by the stopper 18.

- The rebound pawl 17, which was located on the extraction side, moves to the front side and engages the limit switch LS3 to stop the clutch motor M.

When the next gypsum board 4 is fed in this state, its leading end is supported by the rear end of the interval regulating plate 14, and the above operation is repeated in the state shown in FIG. 1.

Although the rail 12 in the embodiment described above moves up and down in a horizontal state, it is also possible to move only one end of the rail 12 up and down.

Further, instead of the plasterboard 4, a splint such as a glass fiber board may be used.

In this way, the spacing regulating device according to the present invention is provided with a spacing regulating plate on a sliding body that is supported on a rail on a transfer path so as to be able to advance and retreat. When this gap regulating plate is held between both boards and the running speed of the rear plasterboard is synchronized with that of the preceding plasterboard, it is pulled up to create a gap of a predetermined size between both boards. Since the gypsum board is intended to be formed, it is possible to continuously supply a fixed length of gypsum board on a metal plate while maintaining a constant interval, thereby saving labor in supplying gypsum board and making it possible to This allows the gap between the boards to be kept constant at all times, allowing for accurate cutting of metal plates.
