It is a reinforcing bar cage manufacturing device that is integrated by inserting the reinforcing bars, and the above-mentioned vertical interval adjustment mechanism advances two flat meshes horizontally at a vertical interval corresponding to the maximum cage thickness, and then abuts against the stop material attached to the welded part. Equipped with a lower conveyor and left and right horizontal supports or receiving conveyors located between these,
Each of the above-mentioned conveyors, supports, and attached guide plates are all supported by a fixed support frame on one side and a movable support frame that can approach and move away from this, and the position of the movable support frame can be changed according to the width of the basket. , the upper stage conveyor is a pair of left and right chain conveyors, and the left and right conveyors open the chain conveyor to the left and right in order to drop the upper stage flat screen, which has been made impossible to move laterally by the left and right guide plates, onto the receiving rack or the receiving conveyor. Having a frame drive mechanism, and the horizontal rail or receiving conveyor,
The upper flat net that has fallen between the left and right vertical guide plates is supported by crank arm ends that are pivotally supported at multiple locations on each of the support frames so that it can move up and down while keeping it horizontal.
It is characterized by being able to be received at a position at a required interval above the lower flat screen.

Has 21. Immediately below it, a lower receiving conveyor 22 is provided at the same height as the lower horizontal passage (conveyor) 13 of the stacking device, and receives the lower flat screen B at the same height. This conveyor 22 is made up of magnetic rollers with multiple circumferential grooves lined up at appropriate intervals in the direction of travel, and the mutual spacing between the multiple circumferential grooves of each roller is matched to the maximum spacing between vertical bars of reinforcing bar cages determined by the standard. .
Therefore, according to the standard, the reinforcing bar flat mesh and the reinforcing bars are always fed into one of the roller circumferential grooves. In this embodiment, the rightmost reinforcing bar of the lower flat screen is inserted into the roller circumferential groove at the right end (left end in FIG. 3) and advanced. If the width of the flat screen is narrow, there will be no vertical streaks in the left roller circumferential groove.

When the upper fall guide plate 26a opens outward,
Since it will be located directly below it, the upper flat mesh A
From beginning to end, the side edges are surrounded by guide plates and fall directly below, stopping directly above the lower flat screen B. Upper and lower flat mesh A,
A guide material may be added to prevent front and back deviations from occurring in the overlap of B, or a correction mechanism may be added after a fall.
In the next step, that is, when the upper and lower meshes are drawn into the welding position, they should be placed in the correct relative position, and after pressing the spacing pieces C on both sides as shown in FIG. 6, welding can be performed by a robot.

を真下へ落せるようにすればよいのである。 Although one embodiment has been described above, it is natural that this invention can be modified and applied as appropriate depending on the implementation conditions and the well-known techniques of the engineer in charge. Before putting it into the welding device W, it is sufficient to receive it vertically at the same height so that the upper flat screen can be dropped straight down.
＜発明の効果＞
この発明は従来、全自動鉄筋篭製造装置は最も
需要の多い寸法の鉄筋篭を量産する専用装置とさ

可能とした常識を覆えした。<Effects of the Invention> This invention has made it clear that conventionally, fully automatic reinforcing bar cage manufacturing equipment was considered to be a specialized device for mass producing reinforcing bar cages of the most demanded dimensions, and that it was impossible to apply this to products of many different dimensions. It defied common sense.

時間を要しない能率上の効果も大きい。 The biggest problem in converting a conventional specialized device into a general-purpose device is that the flat screen sent at regular intervals above and below is changed to the required spacing, so the purpose can be achieved without making the space and site occupied by the device larger than before. It was there. This invention has achieved its purpose by replacing the correction vertical conveyor, which conventionally used a stacking device to correct the vertical relationship between the flat screens stacked one above the other and then sending them to the welding part, to a vertical interval adjustment mechanism. Moreover, the process of dropping the upper flat screen is carried out during the stopping period when the upper and lower flat screens are temporarily stopped for welding and then intermittently advanced to the welding position, so no extra time is required to adjust the spacing. It also has a large efficiency effect.

位置決めする最も簡素有効な手段である。 The upper and lower flat screens are fed in a stacked manner with a vertical interval that matches the maximum thickness of the basket, and the lower flat screen is received at the welding preparation position at the same height, and the upper flat screen is also placed at the same position at the same height. After accepting it, let the latter fall directly below,
In addition to the spatial and temporal effects mentioned above, the spacing adjustment mechanism of the present invention, which is received by a receiving beam of the required height, is the simplest and most effective means for positioning the flat mesh that makes up the reinforcing bar cage for large concrete slabs using only gravity. .
