Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall panel reinforcing plate bending machine for processing a side end of an outer wall panel reinforcing plate. 2. Description of the Related Art Conventionally, as a wall material used for an outer wall of a building, a base material made of concrete, wooden board, or the like,
A reinforcing plate is adhered, and a frame material having a substantially U-shaped cross section is fixed to the four sides on the upper side of the reinforcing plate with its opening facing outward, and further a space surrounded by the reinforcing plate and the frame material is formed. There is an outer wall panel filled with a heat insulating material such as glass wool. When manufacturing the outer wall panel, the protruding portion which is the side end of the reinforcing plate protruding from the peripheral edge of the base material is folded inward by about 180 ° in order to engage so as to sandwich the U-shaped lower plate of the frame material. I need to tune. [0005] The bending operation of the reinforcing plate is performed by using a bending machine 90 shown in FIG. The folding machine 90 has a configuration in which a plurality of press rolls 92 are installed beside a conveyor 91 including a plurality of transport rollers for transporting an outer wall panel 93. FIG. 8 is an enlarged view of a processing portion of an outer wall panel 93 composed of a base material 94, a reinforcing plate 95, a frame material 96 and a heat insulating material 97 by one press roll 92 of a bending machine 90. The protrusion 9 of the reinforcing plate 95 abutting on the inclined surface 98 of the press roll 92 according to the movement of the conveyor 91.
5 a is bent so as to rotate the press roll 92 and follow the inclined surface 98 of the press roll 92. [0005] Each press roll 92 has an inclined surface 98 with which the reinforcing plate 95 abuts for each press roll 92 so that the bending angle of the reinforcing plate 95 gradually increases as the transport of the outer wall panel 93 progresses. Since the angle is set, as the outer wall panel 93 is conveyed, the protruding portion 95a of the reinforcing plate 95 is gradually bent inward so as to sandwich the lower plate 96a of the frame member 96, and finally, the frame The member 96 can be bent so as to be in close contact with the upper part of the lower plate 96a. [0006] The force in the bending direction by the press roll 92 directly acts on the inclined surface 98 of the press roll 92 in a direction perpendicular or substantially perpendicular to the outer wall panel 9.
3 is a force acting to slide itself 3 and to lift the outer wall panel 93. However, since the outer wall panel 93 itself has a considerable weight, the outer wall panel 93 does not slide horizontally due to the frictional force between the base material 94 and the conveyor 91, and the outer wall panel 93 does not slide due to the weight of the outer wall panel 93. Because the panel 93 does not rise,
The reinforcing plate 95 is bent. However, when the reinforcing plate 95 is difficult to bend for some reason, or when the outer wall panel 93 is small in weight and frictional force is small, the outer wall panel 9 is suddenly caused by vibration or the like.
When the frictional force between the third panel 3 and the conveyor 91 decreases, the outer wall panel 93 easily slides on the conveyor 91. As a result, the function of the press roll 92 becomes insufficient, the bending becomes insufficient, the bending position is shifted, and the bending accuracy is deteriorated. In addition to this, not only can the quality of the outer wall panel 93 not be maintained, but also severely lead to the generation of defective products, and the production efficiency is deteriorated. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide an outer wall panel reinforcing plate bending machine for accurately bending an outer wall panel reinforcing plate. Aim. Means for achieving the above object is to provide a reinforcing plate having a projecting portion of a reinforcing plate projecting laterally of a base material and having a substantially U-shaped cross section above the reinforcing plate. A conveyor for transporting an outer wall panel having a frame member, and a rotatable member provided along a side of the conveyor, and a protruding portion of the reinforcing plate is folded over a peripheral surface thereof to a position where the reinforcing plate is sequentially engaged with the frame member.

An auxiliary roll for a bending machine, which is provided above the conveyor and has an inclined surface formed on the side facing the press roll around the conveyor. The present invention will be described below with reference to the drawings showing an embodiment thereof. 1 and 2 are a front view and a top view, respectively, of an outer wall panel reinforcing plate folding machine 10 (hereinafter, referred to as a folding machine 10) according to an embodiment of the present invention. FIG. 3 is a schematic view of an outer wall panel to be processed. As shown in the drawing, a folding machine 10 comprises a press roll in which a bent surface 12 having a predetermined inclination angle is formed on a side of a conveyor 11 composed of a plurality of conveying rollers and above a peripheral surface thereof. A plurality of folding rolls 13 are provided, and folding machine auxiliary rolls 14 are provided above the conveyor 11 at predetermined intervals so as to face the bending surfaces 12 of the press rolls 13, respectively, and are supported by the frame 15 respectively. It is configured. In FIG. 2, the frame 15 is omitted for convenience. On the other hand, as shown in FIG. 3A, the outer wall panel 20 is made of a base material 21 made of cellular concrete, a wooden board, or the like.
A reinforcing plate 22 made of an iron plate or the like is bonded to one side of
At its four sides, a U-shaped frame member 23 such as an iron frame is fixed with its opening facing outward, and the reinforcing plate 22 and the frame member 23 are fixed.
Is filled with a heat insulating material 24 such as glass wool. The side end of the outer wall panel 20 is shown in FIG.
As shown in the cross-sectional view of (b), the protruding portion 22a of the reinforcing plate 22 is bent and engaged so as to sandwich the lower plate 23a of the frame member 23. In the manufacturing process of the outer wall panel 20, as shown in FIG. 3C, the protruding portion 22 a of the reinforcing plate 22 protruding to the side of the base 21 is bent and processed. The machine 10 performs a bending process on the protruding portion 22a of the reinforcing plate 22. Hereinafter, each part of the folding machine 10 will be described in detail in order. The conveyor 11 is composed of a plurality of rotating cylindrical conveying rollers arranged in a line on a frame 15, and is driven by a driving source (not shown) to rotate, thereby setting an outer wall panel set on the conveyor 11. 20
Is transported. The conveyor 11 may employ means other than the transport rollers. The press roll 13 is provided on the conveyor 1
A substantially cylindrical roller provided with a plurality of bent surfaces 12 each having a predetermined angle of inclination formed on the side of the roller 1 and having a predetermined inclination angle. Each of the press rolls 13 is freely rotatably supported by the frame 15 such that the conveying surface of the conveyor 11 and the rotation outer peripheral surface thereof are orthogonal to each other. Then, the protrusion 22a of the reinforcing plate 22 protruding from the outer wall panel 20 conveyed by the conveyor 11 comes into contact with the bent surface 12 which is an inclined surface formed above the peripheral surface thereof, and rotates the press roll 13; It will be bent so as to be guided to the bending surface 12. FIGS. 4 (a) to 4 (f) show six press rolls 13A, 13B, 13C, 13D, 13E, 13F on which a bent surface 12 having a gradually increasing inclination angle is formed.
The press rolls 13 are provided in order from the press rolls 13A in the transport direction. That is, the press roll 1 is used as the first-stage press roll 13.
3A is installed, the press roll 13B is installed as the second stage, and the press roll 13F is installed as the final sixth stage. Here, six press rolls 13A to 13F having different inclination angles are used, but the number of the installation rolls and the inclination angle are set appropriately in accordance with the outer wall panel 20 to be processed. It is not limited to this example. For example, in order to process the outer wall panel 20 using the thicker reinforcing plate 22, the reinforcing plate 22 is hard to be bent. Therefore, it is desirable to increase the number of press rolls 13 to bend little by little and easily. If a foldable reinforcing plate 22 is used, the number of press rolls 13 can be correspondingly reduced. For convenience of explanation, only when it is necessary to explain individual press rolls, press rolls 1
3A, 13B, 13C, 13D, 13E, 13F, etc., are individually described. When there is no need or there is no possibility of misunderstanding, the press roll 13 is described without distinction. The folding machine auxiliary rolls 14 are provided opposite to the respective press rolls 13 at a predetermined distance above the conveyor 11 and are provided on the support shaft 16 via a bearing (not shown). It is fitted and supported rotatably perpendicular to the transport surface. Each folding machine auxiliary roll 14
Are each formed in a substantially cylindrical shape by an inclined surface 17 whose peripheral surface is cut off at a predetermined inclination.
Is held at a position where it comes into contact with one corner of the frame member 23 of the outer wall panel 20 to which the sheet is conveyed. This is frame 15
Is adjustable in the vertical direction and the horizontal direction (the direction parallel to the conveying roller), and is adapted to various outer wall panels 20 having various panel thicknesses and frame material shapes. This is because the position of the folding machine auxiliary roll 14 is adjusted. Thus, the outer wall panel 20 conveyed between the press roll 13 and the press roll 13 is sandwiched and supported. The bending machine 10 configured as described above is
It will be used in the step of bending the reinforcing plate 22 when manufacturing the outer wall panel 20. Next, the operation of the folding machine 10 in the bending step will be described. First, as shown in FIG.
As shown in (c), the outer wall panel 20 before processing in which the protruding portions 22a of the reinforcing plate 22 protrude laterally from the base material 21.
Is set. The outer wall panel 20 set on the conveyor 11 is conveyed along the conveyor 11 and passes through the first-stage press roll 13A when passing through the first-stage press roll 13A.
A protruding portion 22a of the reinforcing plate 22 protruding from the bent surface 12 of FIG.
5A, and bends so as to be guided to the bent surface 12 as the sheet is further conveyed. As shown in FIG.
Is bent at almost the same angle as the inclination angle. At this time, the folding machine auxiliary rolls 14 provided opposite to each other closely contact one corner of the frame member 23 and support the frame member 23, that is, the outer wall panel 20. In response to the further transport in this state, the protruding portions 22a of the reinforcing plate 22 on the side on the press roll 13A side are sequentially bent at a predetermined angle. As the transport proceeds, when it reaches the second-stage press roll 13B, the reinforcing plate 2 bent at the first stage
The second protruding portion 22a comes into contact with the bent surface 12, and is guided to the bent surface 12 of the second-stage press roll 13B in the same manner as the first stage, and as shown in FIG. The protruding portion 22a of the plate 22 is bent further deeply. In the second press roll 13B,
The folding machine auxiliary roll 14 facing this supports the frame member 23. Similarly, the third to fifth press rolls 1
3C, 13D, and 13E, the same process is performed. As shown in FIGS. 5C to 5E, the protruding portion 22a of the reinforcing plate 22 has the inclination angle of each bent surface 12 and Folded at the same angle. Similarly, after passing through the sixth-stage press roll 13F, as shown in FIG. 5 (f), the protrusion 22a of the reinforcing plate 22 which initially protrudes outwardly becomes the lower plate 23a of the U-shaped frame member 23. It comes into close contact and engages so as to be folded upward. Also, in any of the press rolls 13C, 13D, 13E, and 13F, since the folding machine auxiliary rolls 14 facing each other support the frame member 23, the outer wall panel 20 does not move in the direction away from the press rolls 13. Has been blocked. By performing such a process on each of the four sides of the outer wall panel 20, the base material 2 of the outer wall panel 20 is formed.
1, all the protruding portions 22 a of the protruding reinforcing plate 22 can be bent and engaged with the lower plate 23 a of the frame member 23 fixed to the reinforcing plate 22, and the frame member 23 is
Can be fixed firmly. As described above, the folding machine auxiliary rolls 14 are arranged so as to sandwich the outer wall panel 20 between the press rolls 13 at predetermined intervals in opposition to the press rolls 13.
The folding machine auxiliary roll 14 is provided in FIG.
As shown in FIG. 3, the frame material 2 is displaced obliquely from above the frame material 23 by the inclined surface 17 so that the flexible heat insulating material 24 is pushed away.
In order to support one corner of the outer wall panel 3 and firmly hold the lateral position of the outer wall panel 20, regardless of the pressure applied by each press roll 13, the outer wall panel 20 that tries to cause side sliding is stopped, and the outer wall panel is pressed. 20 is surely prevented. At this time, even if the transport of the outer wall panel 20 by the conveyor 11 proceeds, the folding machine auxiliary roll 14 also rotates around the support shaft 16 in synchronization, so that one corner of the frame member 23 of the outer wall panel 20 is always supported. The displacement of the panel 20 can be always prevented. For this reason, it is possible to always maintain a predetermined positional relationship between each press roll 13 and the outer wall panel 20 and its reinforcing plate 22, and each press roll 13 can perform a predetermined function. Projection 22a of reinforcing plate 22
There is no possibility that the bending of the wire becomes insufficient or the bending position shifts. As a result, the protrusion 2 on the side of the reinforcing plate 22
The bending accuracy of 2a can be kept constant, the quality of the outer wall panel 20 can be improved, and the occurrence of defective products can be prevented, and the production efficiency can be improved. In the above description, the processing for one of the four sides of the outer wall panel 20 by the conveyor 11 has been described. For example, the conveyor 11 is arranged in a U-shape, and the press rolls 13 are also formed. If it is arranged in a U-shape in accordance with the arrangement of the conveyor 11, processing of all sides can be performed in one process. That is, one side in the longitudinal direction of the outer wall panel 20 is processed in the conventional process, two sides in the short side direction are processed simultaneously in the transverse process, and the other side in the longitudinal direction is processed in the return path process. Transfer of the outer wall panel 20 in different directions by the conveyor 20 is performed by conventional means. In this way, the outer wall panel 20 does not need to be re-stacked every time the direction changes, and it returns to the original position, so that the work efficiency is improved. As described above, the folding machine 10 is provided with the folding machine auxiliary roll 14 when performing the bending process of the protruding portion 22a of the reinforcing plate 22 of the outer wall panel 20. The displacement of the outer wall panel 20 during the bending process can be prevented, and the bending accuracy can be improved. As is apparent from the above description, the reinforcing plate bending machine for an outer wall panel according to the present invention is rotatably provided on a side of a conveyor composed of a plurality of conveying rollers and the like, and has a predetermined surface. A plurality of press rolls formed with a bent surface having an inclination angle of, and auxiliary rolls for bending machines facing each press roll so as to sandwich an outer wall panel together with each press roll, The outer wall panel is supported so as to be sandwiched by the press roll and the folding machine auxiliary roll. As a result, lateral displacement or the like during processing is prevented, and each press roll can always perform a predetermined bending operation, and the bending accuracy can be kept constant. As a result, the occurrence of defective products can be suppressed, and a bending machine with high production efficiency can be provided.
