Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a guide device for a set rod in reinforcing bar block assembly used in the manufacturing process of ALC.

(Prior Art) Conventionally, when inserting a set rod into a spacer of a reinforcing bar, no separate guide device was provided. As a countermeasure for the misalignment of the set rod, the only measure taken has been to make the tip of the set rod at an acute angle.

(Problem to be Solved by the Invention) However, in assembling a reinforcing bar cage block by lowering the set bar and inserting it into the spacer of the reinforcing bar cage, it is difficult to assemble the reinforcing bar cage block by lowering the set bar and inserting it into the spacer of the reinforcing bar cage. Due to misalignment of the spacer, misalignment between the spacer hole of the reinforcing bar and the set rod is likely to occur. Therefore, if no measures are taken, the setting frame may not fit properly into the spacer of the reinforcing bar cage, and the reinforcing bar cage cannot be suspended and the reinforcing bar block blocks may not be properly assembled.

Further, the method of making the tip of the set rod at an acute angle is not effective because the amount of misalignment that can be tolerated is small.

Furthermore, a method of arranging a funnel-shaped guide above the spacer can be considered, but the mechanism would be complicated, such as having to be constructed so that the funnel can be divided in order to retract the guide after the set rod is inserted, and this is not appropriate.

(Means for Solving the Problem) Therefore, in order to solve the above problem, when the set rod is lowered and inserted into the spacer of the reinforcing bar, the rotating It is characterized by having a bow tie-shaped butterfly guide attached to the shaft and a lifting means for moving the butterfly guide to a predetermined height, and guiding the set rod attached to the set frame to the spacer of the reinforcing bar. A guide device for a set rod in reinforcing bar block assembly was constructed.

(Function) In the guide device of the present invention as described above, when the set frame descends and fits between the bow tie-shaped butterfly guides, the butterfly guide is rotated and the set rod is inserted in the center of the set frame. It is designed to hold the set rod and guide the tip of the set rod to the spacer of the reinforcing bar.

As shown in Figure 22, an alignment table (7) is waiting below 7), and on top of this alignment table (7) are the alignment guide rods (9) (9) of the alignment jig (8). Reinforcement bars lined up between (a
) are aligned.

- Operate the servo motor (49) again to lower the set frame (17) held by the set frame clamp device (34).

■ By lowering the set frame (17) in this way, the set frame (11) suspended from the set frame (17)
) are adjacent butterfly guides (86
), resulting in the state shown in Figure 1. Note that since the cylinder (91) of the guide device (36) is still shortened, the butterfly guide (86) is in a vertical state as shown in Fig. 5, and the butterfly guide (86) is set between the butterfly guides (86). The frame (11) can be easily inserted into the frame.

■ Once the set frame (11) is fitted between the butterfly guides (86) as described above, operate the cylinder (91) to lay the butterfly guide (86) sideways, and as shown in Fig. 3, its central part ( 87) to hold the set frame (11).

■ In this way, the set frame (11) is attached to the butterfly guide (
86), shorten the cylinder (75) of the guide device (36), pull down the butterfly guide (86), and place the set frame (
11) Guide the tip.

■ As described above, the tip of the set frame (11) is reliably guided to the spacer (3) by the guide device (36), and then the hook (12) at the lower end of the set frame (11) is connected to the reinforcing bar ( a) Once inside the lower spacer (4), use the rotation device (67) to rotate the lever (15) at the upper end of the set frame (11) to turn the hook (12).
By engaging the bulge (1B) (19) and the spacer (4), the reinforced sieve block (
25) can be assembled.

(Effects of the Invention) In any case, according to the guide device of the present invention, the set rod held between the butterfly guides can be guided to the spacer of the reinforcing bar. Even if there is a misalignment between the reinforcing bar spacer hole and the set rod due to misalignment, the set frame can now be inserted smoothly into the reinforcing bar spacer, and the reinforcing sieve block This has the effect that the assembly process is carried out smoothly.

In addition, since the butterfly guide can be rotated to hold the set rod in the center of the guide, the amount of misalignment that can be tolerated is greater than when the tip of the set rod is made at an acute angle.
It is effective and has the advantageous feature that it does not require a complicated mechanism such as means for arranging a funnel-shaped guide above the spacer.
