Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for drawing out a wire mesh, and in the case of obtaining a wire mesh used for various concrete structures as a wire mesh, the wire mesh drawn after welding is neatly packed. It is intended to provide a method and an apparatus thereof which can be easily piled up and supported on a sheet and can be easily and accurately handled after that.

[0002]

2. Description of the Related Art It is indispensable to arrange reinforcement not only in concrete fixed structures but also in pre-packed concrete products such as box culverts and drains, and such reinforcements are welded to vertical and horizontal bars. It is indispensable to use the prepared welded wire mesh.

Therefore, in order to mass-produce such a welded wire mesh, the applicant of the present invention has not been using the welding machine for a long time, and the chuck mechanism for pulling out the welded wire mesh onto the pedestal has been on the side of the applicant for more than ten years. Previously developed, it is now possible to produce a sufficiently efficient welded wire mesh.

[0004]

By the way, it is necessary to stack a certain number of wire nets obtained by welding as described above and tighten them with a metal wire or the like to carry, load, store and carry. For this purpose, a large number of the wire nets drawn out as described above should be placed in an orderly manner on the pedestal. However, it is not easy to place a wire net with a certain length on the pedestal while pulling it out, that is, the middle of the drawn wire net hangs down and comes out in contact with the surface of the wire net previously placed. Because of the action, the preceding wire mesh moves and it is difficult to obtain an orderly stacked state. Such a relationship is particularly remarkable in recent years due to the long and large diameters of the wire mesh being 6 m and 8 m.

Further, the wire net drawn out as described above is bent and hung down so as to be in contact with the surface of the previously deposited wire net,
Since the length of the vertical reinforcing bar between the chuck and the welding machine becomes long, the intervals between the horizontal reinforcing bars to be welded to the vertical reinforcing bar become non-uniform, and the concrete reinforcement performance such as the concrete reinforcement performance obtained by the wire mesh can be properly obtained. There will be no.

Although it is conceivable that an operator operates the drawn wire mesh drawn out in order to avoid these disadvantages, as described above, the welded wire mesh having a large length of 6 m, 8 m or more is manually operated. It is very difficult to operate with and the moving operation in contact with the wire mesh surface that has been placed in advance is accompanied by it, so that it is not easy to obtain a large number of ordered sheets.

[0007]

DISCLOSURE OF THE INVENTION The present invention has been studied to solve the technical problems of the conventional ones described above, uses a special movable wire mesh slide, and has a considerable length due to its preferable operation method. Even with a welded wire mesh having, it was possible to receive without substantially contacting the surface of the previously deposited wire mesh, and succeeded in properly carrying out the orderly loading and unloading of the automatic welded wire mesh. It seems that.

(1) The horizontal mesh is sequentially supplied to the longitudinal stripes arranged in the welding machine and the wire mesh extruded while welding is received by the fixed wire mesh slide and the tip side of the welded wire mesh is slid on the wire mesh holder. When the wire mesh is grasped by the movable mesh mechanism and pulled out on the wire mesh pedestal, the lower surface of the wire mesh which is pulled out as described above is supported by the movable wire mesh slide on the wire mesh pedestal, and the fixed position is fixed by the movable chuck mechanism. After pulling up to, the chuck mechanism moves the above-mentioned movable wire mesh slide while holding one end side of the weld wire mesh to support the other end side of the weld wire mesh on the wire mesh support base, and thereafter by the movable chuck mechanism. A method for pulling out a welded wire net, characterized by releasing the grip and placing the entire welded wire net on a wire net pedestal.

(2) A wire mesh welding machine for sequentially supplying and welding horizontal stripes to arranged longitudinal stripes, a fixed wire mesh slide installed in front of the wire mesh welder and further in front of the fixed wire mesh slide. And a movable chuck mechanism for grasping and pulling out the leading end side of the wire mesh welded onto the fixed wire mesh slide table on the fixed wire mesh support table, and fixing the wire mesh support table on both sides of the wire mesh support table. Welded wire netting characterized in that a movable wire netting slide having a guide means projecting in the direction of the wire mesh slide and facing the fixed wire mesh slide is provided by the guide means. Drawer device.

[0010]

A movable chuck that receives a wire mesh extruded while sequentially supplying horizontal bars to the longitudinal bars arranged in the welding machine and welding the fixed wire mesh slide base, and sliding the tip end of the welded wire mesh on the wire mesh support base. When the wire mesh is held by a mechanism and pulled out onto the wire mesh support, the movable mesh slides on the wire mesh support so that the lower surface of the wire mesh is supported by the movable chuck so that the movable mesh pulls the wire mesh out of the welding machine. While being supported by a movable wire mesh slide, the wire mesh is pulled out to prevent the wire mesh from adhering to the preceding wire mesh surface and the accompanying movement of the wire mesh. The movable wire mesh slide is set at a position suitable for preventing the sliding contact according to the length of the wire mesh to be applied.

After the movable chuck mechanism is pulled out to a fixed position, the chuck mechanism moves the movable wire mesh slide table while holding one end side of the welding wire mesh, and the other end side of the welding wire mesh is placed on the wire mesh support table. And then the grip of the movable chuck mechanism is released to place the entire welding wire net on the wire net pedestal so that the other end side is first placed on the pre-deposited wire net. One end side is released and the whole wire mesh is placed, and there is no movement of the wire mesh under the condition of being in contact with the preceding wire mesh, so that accurate deposition without sliding can be obtained.

It is to be noted that the wire mesh drawn out as described above is prevented from being greatly bent by being supported by the movable slide, and the welding interval of the horizontal bar in the welding machine is maintained substantially appropriately. Equalize the reinforcing performance and other characteristics.

A wire mesh welding machine for sequentially supplying and welding horizontal bars to arranged longitudinal bars, a fixed wire mesh slide installed in front of the wire mesh welder, and a wire mesh installed further in front of the fixed wire mesh slide A cradle and a movable chuck mechanism for gripping and pulling out the front end side of the wire mesh welded onto the fixed wire mesh slide on the pedestal and the wire mesh pedestal are sequentially provided in the welding machine to sequentially weld the wire mesh having the horizontal bar welded. Pull it out.

On both sides of the above-mentioned wire mesh pedestal, there is provided guide means opposed to each other so as to project toward the fixed wire mesh slide, and the guide means moves the wire mesh from the wire mesh pedestal toward the fixed wire mesh slide. Since the movable wire mesh slide is positioned at an appropriate position according to the length of the wire mesh to be applied by providing the wire mesh slide, the rear part of the wire mesh pulled out by the chuck mechanism is supported and the drawn wire mesh is pre-deposited. Prevent contact with wire mesh.

As described above, by preventing the drawn wire netting from joining to the lower deposited wire netting, the movement of the deposited wire netting is prevented and a proper deposition state is formed.

Although the withdrawal of the drawn wire net after the drawn wire net is drawn to a predetermined position as described above can be carried out in an appropriate order, the preferred release order is to first withdraw the movable wire net slide and then withdraw the rear end in the drawing direction. By releasing the front end in the drawing direction after the rear end in the drawing direction comes into contact with the ground, the sliding force due to the movement of the drawing wire net does not act on the lower deposited wire net at all.

As described above, the pulling-out force of the drawn-out wire net does not affect the lower piled wire netting, and the pull-out and drop-out operations are repeated to enable orderly loading and loading of the wire nets, and the subsequent tightening and integration with a metal wire or the like. It is easy and accurate. That is, it is possible to obtain a wire mesh aggregate having an orderly packing shape and facilitate the handling and handling of the wire mesh.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete embodiment of the present invention as described above will be described with reference to the accompanying drawings. As shown in FIG. 1, a predetermined number of vertical stripes 15 are shown in FIG. As described above, it is known that the strips are fed into the insertion portion 12 at a predetermined interval, and the transverse strips 16 are sequentially supplied to such longitudinal strips 15 to be fed between the electrodes 11 and 11 and welded. On the street.

As described above, the automatically welded products are sequentially extruded and received by the fixed wire mesh slide 2 to move forward,
An elevating type wire netting pedestal 3 is provided in front of the fixed slide 2, and as shown in FIG. The pedestals 3 are sequentially received, and the pedestal 3 is lowered by a height corresponding to the height of the received group of wire nets 5 to form a predetermined wire net receiving state.

In the present invention, guide rails 8 are provided opposite to each other on both sides of the drawing portion of the wire mesh 5 as described above, and a movable wire mesh slide 4 is movably provided along the guide rails 8. That is, the slide 4 is adapted to be appropriately moved and operated by a chain 14 driven via a prime mover 9 and a drive connecting shaft 10.

That is, the slide 4 is drawn out from the fixed type wire mesh slide 2 according to the length of the wire mesh 5 to be pulled out in the drawing operation, as shown in FIG. Is set at a position where it does not come into contact with the deposited wire netting 5 on the pedestal 3 even if it is bent, that is, the slide 4 has the wire netting 5
Although the wire mesh 5 supported by the slide 4 has a substantially horizontal state, it is welded in such a manner that the horizontal bar 16 is arranged at a substantially constant interval with respect to the vertical bar 15.

As shown in FIG. 1, when the wire net 5 is pulled out to a predetermined position, the wire net 5 is released and dropped. The chuck 6 is released to drop the tip of the wire net 5 and then the movable slide 4 is fixed. The rear end side of the wire mesh 5 can be dropped by sliding in the direction of the slide 2, but by doing so, when the wire mesh 5 may move when the movable slide 4 moves, the movable slide 5 4 first fixed slide 2
To the side, the rear end side of the wire net 5 is dropped, and then the chuck 6 is released and the whole is placed.

That is, in this way, the movable slide 4 is first removed, the rear end side is dropped, and then the grip of the chuck 6 on the front end side is released, so that no moving force is generated in the loaded wire netting and the wire mesh is placed on the pedestal. It can be dropped and always an accurate drop load can be achieved.

It is obvious that the stop of the movement of the chuck mechanism 6 and the stop of the movable wire net slide 4 as described above can be detected by a sensor or the like to reach a predetermined position and an appropriate stop position can be selected. Depending on the operation result of pulling out the welding wire mesh and receiving it on the pedestal 3, the vertical streaks 15 and 2
One wire is arranged in a range of 2000 mm in width, and horizontal bars 16 are arranged at intervals of 50 mm with respect to the vertical bars 15, and 50 pieces of wire mesh having a length of 8 m which are welded are continuously received on the welding drawer receiving table 3. As a result of stacking, there was almost no misalignment between the wire nets, and proper stacking was obtained. Immediately, tie the wire bundles to the vertical and horizontal crossovers at the four corners, and bundle the whole into an integrated package. However, it was confirmed to be suitable for cargo handling by a forklift.

In contrast to such an embodiment of the present invention, when the welding wire net is pulled out and operated in the same manner as described above under the condition that the movable wire net slide is removed, when the upper welding wire net 5 is drawn out, the wire net at the lower part thereof is pulled out. Is 5 to 15
Therefore, it is necessary to always prevent the accumulated wire mesh from sliding even if the automatic drawing operation can be performed, and in the end, there is a deviation of about 2 to 5 mm between the wire meshes. However, it is impossible to achieve an integrated packing style by binding the load condition unless the loading condition is further corrected. Moreover, such alignment operation requires considerable skill and man-hours. .

[0026]

As described above, according to the present invention, it is possible to accurately position and deposit a welded wire net obtained by efficiently welding between electrodes, and bind the wire net with a stable packing shape as it is for loading and unloading. An invention which has a large effect industrially because it can be easily obtained as an aggregate, and it is possible to smoothly form a preferable accumulated aggregate state even in the case of a large-sized and oversized welded wire mesh in recent years and to facilitate its handling and arrangement. Is.
