DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, a caulking filling device 1 of the present invention can fill a caulking material 9 into the joint 6 between the exterior members 7 adjacent to each other with a joint 6 therebetween, and measures the width of the joint 6 The caulking material 9 is controlled by controlling the amount of caulking material injected per length of the joint 6 according to the width of the joint 6 measured by the measuring unit 2 and the joint width measuring unit 2.
And a caulking filling section 3 for filling the joints 6 into the joints 6.

In the present embodiment, the exterior material 7 is attached to the upper surface of a rectangular frame A via a base plate B, and has, for example, two linear joints 6 between the exterior materials 7. An outer wall panel (hereinafter, referred to as a panel P) is formed, and the joint width measuring unit 2 is formed on the panel P by belt conveyors 20A and 20B with three exterior members 7 facing upward.
It is carried in.

In the present description, the belt conveyor can be replaced with various other conveying means such as a roller conveyor.

The joint width measuring unit 2 is a belt conveyor 21 for moving the joints 6, 6 while positioning and positioning the panel P thereon in the flow direction, and stands upright on both sides of the belt conveyor 21. Horizontal shaft 23 extending between the upper frames 22A, 22A of the portal frames 22, 22 and extending at right angles to the flow direction of the belt conveyor 21.
And a detection unit 11 attached via an L-shaped metal member 25 below each of, for example, two moving bodies 24, which are movably disposed along the support shaft 23 using an appropriate driving tool. Equipped.

In the present embodiment, the detecting unit 11 has a cylinder 27 having a rod 26 which expands and contracts at right angles to the flow direction of the belt conveyor 21, and is fixed to a protruding end of the rod 26 and faces downward from the lower surface. And a laser sensor 29 that emits laser light.

The cylinder 27 is provided with a laser sensor 2.
An encoder for counting an OFF pulse signal (code) generated when the joint 9 detects the joint 6 is provided.

The moving body 24 moves the joint 6 of the panel P on the belt conveyor 21 to a position where the laser beam from the laser sensor 29 can cross over by the expansion and contraction of the rod 26 of the cylinder 27. Has been moved by

The count signal corresponding to the width of the joint 6 detected by the laser sensor 29 is sequence-controlled by a dedicated sequencer for count calculation of the control device 12 to increase the accuracy of measuring the width of the joint 6.

The detecting unit 11 for measuring the width of the joint 6 may employ various types such as an ultrasonic sensor type and an image processing type, in addition to the type using the laser sensor 29.

The detecting section 11 of the joint width measuring section 2 of the present embodiment.
Since the width of the joint 6 is measured in a non-contact manner without directly contacting the exterior members 7 on both sides of the joint 6, the exterior material 7 is not damaged, and the quality can be kept good.

The panel P whose joint width measurement unit 2 has measured the width of the joint 6 is sent to the belt conveyor 30 connected to the belt conveyor 21 with the joint 6 directed in the flow direction. Thus, the two joints 6, 6 are filled with the caulking material 9, 9.

The caulking filling section 3 is bridged between the belt conveyor 30 and the upper frames 31A, 31A of the portal frames 31, 31 erected on both sides of the belt conveyor 30, and the caulking filling section 3 is connected to the belt conveyor 30. A horizontal receiving shaft 32 extending at right angles to the flow direction, and a caulking material 9 is continuously filled along the receiving shaft 32 into the joints 6 while being movably arranged by a suitable driving tool and transporting the panel P. Coating guns 13, 13.

The discharge pressure of the coating gun 13 is determined by the controller 12 according to the width of the joint 6 measured by the joint width measuring unit 2, ie, the count signal. The caulking height in each of the two joints 6, 6 is controlled to be substantially constant.

The caulking material injection amount can be controlled by changing the speed of the belt conveyor 30 by the control device 12 according to the count signal, as shown in FIG.

In this case, one of the joints 6 having different widths
Since the caulking material 9 cannot be filled at one time on one belt conveyor 30, another belt conveyor 33 is continuously provided adjacent to the belt conveyor 30, and one on each belt conveyor 30, 33 whose speed is controlled respectively. Each of the joints 6 is filled with a caulking material 9.

Instead of moving the panel P, as shown in FIG. 4, the receiving shafts 32A and 32B each having one of the application guns 13 and 13 attached thereto are connected to the belt conveyors 30 and 33 by using a reduction motor 34 or the like. Joint 6 while moving in the flow direction
The caulking material 9 can be filled therein.

At this time, the control of the caulking material injection amount is performed by controlling the reduction motor 34 by the control device 12 according to the width of the joint 6 and changing the moving speed of the receiving shafts 32A and 32B.

As shown in FIG. 5, the joint width measuring unit 2
The cylinder 27 and the application gun 13 of the caulking filling unit 3 may be provided integrally to fill the cone conveyor material 9 on the belt conveyor 21.

Further, as shown in FIG. 6, the detecting portion 11 is provided on the joint 6 with a joint width measuring jig 3 for decreasing the diameter downward.
7 may be dropped, and the amount of the drop may be read by the displacement sensor 39.

Further, as shown in FIG. 7, a joint width measuring jig 42 having a turning tool 41 which moves while rotating from one end to the other end of the joint 6 while dropping into the joint 6 is used. The displacement sensor 43 detects the vertical movement of the measuring jig 42.
Can also be read with.

At this time, the width of the joint 6 is continuously measured over the entire length of the joint 6 and stored in the storage unit of the control device 12, and accordingly, the injection amount of the caulking material from the application gun 13 is determined. Fine control can be performed corresponding to the total length of the joint 6.

In this embodiment, the panel P has two joints 6,
Although six are provided, the number of joints 6 is not limited to this, and one or three or more joints 6 may be formed. Further, the detection unit 11 can be made movable along the flow direction of the belt conveyor 21 by, for example, moving the support shaft 23. It may be controlled.

Further, in the case where there is a joint which intersects the joint 6 at a right angle, the direction for detecting the joint width (for example, the direction in which the rod 26 expands and contracts) and the moving direction are determined by the flow directions of the belt conveyor 21 and the belt conveyor 30. It is also possible to provide a detection unit 11 and a coating gun 13 which are parallel and at right angles.
