する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically dividing and positioning a band-shaped metal grid material in a manufacturing facility for a metal grid (grating) which is often used as a road groove or a lid for a trough.

m long vertical member between the lattice width (for example, 350 mm to 450 m
m) is arranged in parallel, and a horizontal bar is resistance-welded on its upper surface at a required pitch to form a band-shaped lattice material (commonly called original plate), which is divided into product dimensions and the front and rear end plates are welded to finish. 5 and 6 show one end of the metal grid material before cutting, 1 is a vertical member, 2 is a horizontal bar, A is a product size, α is a cutting margin, C is a planned cutting position, and P 1 is a product. The horizontal bar pitch, P 2, is the horizontal bar pitch that has become longer because it includes the planned dividing position C.

誤差が出る。In order to make this strip-shaped grid material, when resistance welding of the horizontal bars 2 to the vertical materials 1 in parallel one after another, normally, the welding position of the horizontal bars 2 is instructed by NC control, and the pitch error (± 0 .2
It is suppressed to about 0.5 mm). Welding the vertical bar 1 and the horizontal bar 2 involves a large work deformation in which the horizontal bar is inserted into the upper edge of the vertical bar.
Due to thermal expansion and contraction distortion peculiar to resistance welding, some pitch error is inevitable. Even with a slight error, when a large number of horizontal bars are welded to a long material of 6 to 8 m, the error accumulates and becomes large. The control engineer has devised so that it does not accumulate, but there are errors that cannot be controlled due to the feed error of the vertical member 1, the cross-sectional shape of the horizontal bar 2, the error of the supply position, the welding current, the fluctuation of the applied pressure, etc. Come out.

れ以上に横棒２と分断端との距離が狂ってくる。As described above, since the long grid material has a certain degree of horizontal bar pitch error, if it is sequentially divided by the product length A, the drawing will be performed later. The difference from the size increases, and in particular, the dividing position C in FIG. 3 deviates from the center of the pitch P 2 . The tolerance of the size of the metal grid, which is a product, is (± 1.5 to 2.0 mm), but the distance between the horizontal bar 2 and the divided end is further deviated.

断すれば、製品長さＡの誤差も小さい。As a remedy, it is conceivable to reduce the error in the distance between the horizontal bar 2 and the dividing end within the allowable limit by increasing or decreasing the product length A within the allowable error. For that purpose, it is sufficient to stop mechanically dividing the lattice material sequentially from one end into the fixed dimension A, and give priority to the center C of the pitch P 2 as the dividing position over the dimension A of FIG. If it is divided in such a manner, the error of the product length A is small.

大きな障害があった。However, it is not easy to stop the central point C of the horizontal bar pitch P 2 at the cutting position each time as compared with the case where the positioning is simply performed with a fixed size and the cutting is performed. Since the target grid members have different dimensional errors from one sheet to another, if it is to be automated, the positions of all the horizontal bars 2 are detected one after another, and a computer control is used to indicate the center C of the pitch P 2 and stop it. The concept of the control device comes to mind easily. However, since the horizontal bar 2 of the actual metal lattice material has an irregular cross section in which a square bar is twisted, accurate position detection cannot be performed. The present inventors have paid attention to the adoption of a wedge-type pushing method, which is the origin of mechanical positioning, as a dividing positioning device suitable for an actual metal grid material. However, there were three major obstacles to this.

Has a narrow mutual gap of 10 to 25 mm, and the pitches P 1 and P 2 of the horizontal bars 2 and 2 are 80 to 150 mm, it is difficult to push the positioning wedge, and the other is that even if the wedge is pushed in. , It is difficult to move the whole long and heavy lattice material, and the other one is because the place to push the wedge runs the cutting device, so if you lower the wedge from a high position, the wedge will correct the position. It is not possible to endure the horizontal reaction force of time. This invention overcomes the above three obstacles.

Centering material, a pair of left and right guide drive mechanisms that vertically elevate and lower the pair of centering materials against horizontal external force, the guide drive mechanisms are attached to the left and right of the frame, and both columns are provided on both outsides of the lattice material path. By pivotally supporting the portal frame supported by the shaft and the portal frame around the support shaft supporting portion, the centering member and its guide drive mechanism can be moved directly above the cutting position or at the retracted position.

心に合わせる芯出し作用をする。The automatic dividing / positioning device for a metal grid material according to the present invention overcomes the above-mentioned obstacles and performs the dividing / positioning of a long grid material by a wedge type pushing system. First, it is the simplest constant-distance feed mechanism that sends the planned dividing position of the grid material to the cutting position where the cutting device runs, instead of NC control or computer control. All that is needed is to advance the grid material by a fixed distance that is the product size plus the cutting allowance. The wedge-shaped centering material, which is the main part of the wedge-type push-type positioning, is at least a pair of right and left (two or three pairs) downward-pointing wedge plates, which are pushed in from above on the lattice to form the wedges. The horizontal bar is pushed by the inclined part of the side end surface of the mold to perform the centering action of aligning the center of the horizontal bar pitch with the cutting position center.

水平外力に耐えるのである。The centering action by pushing the pair of centering members pushes the heavy strip-shaped grid member and thus involves a large horizontal reaction force. However, the guide driving mechanism for the centering member and the left and right sides of the beam portion are attached. The gate frame can withstand horizontal external force sufficiently. The columns on both sides of the portal frame are axially supported on both sides of the lattice material path that does not interfere with cutting, and when the cutting device runs at the cutting position, the turning and fixing mechanism works to perform centering. The material and its guide drive mechanism are moved from directly above the cutting device to the retracted position. When returned to the position just above the cutting position, the fixing mechanism works,
It withstands horizontal external forces.

せられるようにする事が出来る。The structure of the above invention requires a supporting means capable of correcting the position of a heavy and long grid material by pushing in the centering material, and in the case of a conveyor, it becomes an expensive facility. In order to avoid this, between the fixed rollers of the normal roller conveyor, light rollers are provided in a scattered manner, and by raising and lowering them all at once, the band-shaped grid material is lifted and the wedge plate The entire length of the lattice material can be adjusted and moved by just pushing.

The present invention has overturned the conventional concept that, when the band-shaped grid material is cut into product dimensions by an automatic cutting device, some dimensional defects are unavoidable. According to the present invention, after the strip-shaped lattice material is fed according to the product size, the horizontal bar pitch center of the cutting position is further aligned with the cutting position center, so that the pitch error is reduced by half, and the product size is allowed within the allowable error. It can be contained within.

As described above. We also presented a lightweight roller mechanism that floats a heavy metal grid material from the stationary roller only when centering it and lightly adjusts its position. Although the present invention is only a dividing and positioning device, the effect of improving the productivity and quality of the metal grid is extremely large.
