The present invention provides an alignment with alignment guides for aligning a plurality of reinforcing steel frames (entangled with reinforcing bars) of concrete products, such as autoclaved light weight concrete (ALC). An alignment jig attachment for mounting a jig on an alignment bogie.

Conventionally, there is one shown in Unexamined-Japanese-Patent No. 1-20094 as an alignment loading of a reinforcing steel frame in an alignment trolley.

It is equipped with an alignment guide for aligning a plurality of reinforcing bar frames at regular intervals, and an alignment guide having a different rotation pitch from the above alignment guide, having a common rotation axis, and having a plurality of alignment guide units provided at 90 ° positions. Reinforcing bar frame alignment.

In Unexamined-Japanese-Patent No. 1-20094, the alignment guide is fixed to the alignment trolley and cannot be easily removed. For this reason, correspondence with different plate | board thickness is limited to two types, and the other board | plate thickness must prepare the other trolley | bogie.

In addition, in order to attach the reinforcing steel frame to a predetermined position in the mold, a spacer attached to the reinforcing steel frame is generally used, but the reinforcing steel frame is relatively flexible, and an alignment guide is necessary near the spacer of the reinforcing steel frame. Do. Nevertheless, in the prior art, no treatment has been made in this respect, and it is practically difficult to cope with different plate thicknesses.

As described above, there have been many drawbacks in producing ALC of different plate thickness in the prior art.

In view of this, the inventors have found out that the problem is solved by using an alignment jig having alignment guides lined up in line with the thickness interval of the reinforcing steel frame, and installing it in accordance with the length of the reinforcing steel frame on the balance. In this way, the plate thickness of the ALC is different. Therefore, even if the thickness of the reinforcing steel frame is different, it is possible to cope by preparing the alignment jig having the alignment guides in line with the thickness interval of the reinforcing steel frame. It has also been found that it is possible to install the alignment guide in the vicinity of the spacer of the reinforcing steel frame by providing the fixing guide for the spacer in the horizontal alignment guide only.

However, when arranging the alignment jig at a predetermined position on the bogie according to the length of the reinforcing steel frame, it is necessary to complete the alignment jig attaching machine because the positional accuracy is higher than that performed by the attraction force.

In view of this, the present inventors have completed the present invention by trying to solve the problem by precisely moving the trolley and attaching the alignment jig to the trolley at a constant position.

The alignment jig attachment device of the present invention supports an elevating frame having an alignment jig supplying device, a gripping mechanism for gripping an alignment guide of the alignment jig, an oscillation stop pin that is caught by the oscillation stop pin insertion hole of the alignment jig, An alignment jig attachment device characterized by having a moving frame moving in a direction perpendicular to the main surface thereof, wherein the alignment jig supply device includes a chain conveyor with an uppermost layer roller, a fixed stopper provided at this end, And a plurality of moving stoppers for alternately stopping and passing the alignment guides provided at predetermined intervals on the substrate. Then, in contact with the edge of the moving range of the moving frame, the shock is alleviated by the reducer, or the starting and ending points of the movement are lowered toward the bogie and the holding jig of the alignment jig of the alignment jig feeder. More preferably.

Further, at the lower end point of the elevating frame, it is more preferable to reduce the impact by installing a reducer for accommodating the horizontal support beam of the elevating frame. It is more preferable because the force is directed downward downward even when touching an obstacle.

In the alignment jig attachment device of the present invention, the moving frame is for moving to the position to lower the alignment jig gripping toward the bogie in the position to hold the alignment jig of the alignment jig supply apparatus, or vice versa, The steel frame is for lowering the alignment jig toward the bogie. The chuck also holds the alignment guide of the alignment jig. However, only by holding the alignment guide with this chuck, there is a fear that the alignment guide will shake when moving, especially when lowering. When the alignment guide is shaken, it becomes difficult to set the alignment guide at a predetermined position on the bogie, so that the apparatus of the present invention is provided with a pin to stop the shake of the alignment guide at a position different from the chuck.

As such, the alignment jig attachment device of the present invention grips the tip of the alignment guide of the alignment jig at a predetermined position on the jig supply device with a chuck, inserts a pin into the swing stopper insertion hole provided in the alignment jig, and then the alignment jig. It is possible to position the alignment jig at the position of the small intestine of the alignment trolley while preventing confusion.
