Abstract

PURPOSE:To enable reinforcing bar cages to be moved transversely in keeping the posture flexible at high speed by transferring reinforcing bar cages in an ALU manufacturing process in the transverse direction (horizontal direction) to the upside between the alignment guide rods of an alignment table while guiding them between a torsion restraining guide and a rear plate. CONSTITUTION:Reinforcing bar cages (a) transferred in a lay-down state by means of a conveyor B are vertically placement-raised by means of a raising device 20. A cylinder 89 is driven and therefore a torsion restraining guide 22 revolves anticlockwise and acts to press the main surface of the reinforcing bar cage (a) held in front of a rear plate 21 on the rear plate 21 therebetween. A running carriage 25 runs in the right direction and serves to bring the reinforcing bar cage (a) immediately above an alignment jig 15 mounted on an alignment carriage 14. By means of an elevating handle 23, a spacer is grasped from the upper surface side of the reinforcing bar cage (a) and, after grasping, the hook of the rear plate 21 is disengaged from the reinforcing bar cage (a). Thereafter, the elevating handle 23 comes down and, at the descending position, the elevating handle 23 releases the spacer, resulting in mounting the reinforcing bar cage (a) onto the cavity 15' of the alignment jig 15.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the production of concrete products, such as autoclave-cured lightweight aerated concrete products (ALC), and in particular, in the production process, reinforcing bars are aligned with guide bars. The present invention relates to a method and device for transferring the materials to a row of sorting tables.

(Background of the Invention) As mentioned above, the present invention relates to a method of transferring reinforcing bars to an alignment table in an ALC manufacturing process, and an apparatus therefor. A brief explanation will be given in advance.

In Fig. 13, (1) shows the electro-hydraulic knitting line (1) for knitting the reinforcing bar (a).
As shown in Figure 14, the reinforcing bar cage (a) made with They are connected by spacers (12).

In the following, in the reinforcing bar (a), the side with the widest area is the main surface (a x), the upper and lower sides where the spacers (12) are arranged are the upper and lower surfaces (az), and the remaining sides are the left and right surfaces. (a
Call it Ito.

The spacer (Step 2) has a hole (Step 3),
The spacer (12) on the upper side (front side in Figure 14) is No. 15.
As shown in the figure, it has a slightly wide hole (13), and the spacer (12) on the lower side (back side in Figure 14) has a slightly narrower hole (13), as shown in Figure 16. .

The reinforcing bars (
a) is carried to the basket transfer device (2) by a conveyor or the like, and the sorting table (in Fig. 19, it is shown as a sorting cart (14) with wheels attached to the sorting table. Hereinafter, the wheels are not necessarily used. Although it is not necessary, for the sake of clarity, an alignment trolley (14
). ) between the alignment guide bars. In the alignment cart (14) shown in Fig. 19, alignment guide rods (15'') and lower space fixed guides (15゛) as shown in Fig. 18 are arranged at predetermined intervals. An alignment jig (15) having a fixing gear (15'') may be mounted on a trolley as shown in the lower part of FIG. 12 by an alignment jig setting device (not shown). The spacing between the alignment guide rods (15'') on the alignment cart (14) is such that the reinforcement bars (a) are lined up parallel to each other at this spacing. (See Figure 19).

When the transfer of the reinforcing bars (a) is completed in the gauntlet transfer device (2), the alignment cart (14) moves to the gauntlet centrifuge device (5), and the spacer holes of each reinforcing bar cage (a) are moved. (
13), a hanging rod (16) is inserted, and a basket block (17) as shown in FIG. 20 is formed. Once the basket block (17) is formed, the alignment cart (14) moves to the station (6) and waits. Then, appropriate ones are selected from among the various basket blocks (17) loaded on the alignment cart (14) and installed in the forming frame (18) as shown in Fig. 21, and then the slurry is Formwork (1
8) When the mortar expands approximately four times, it is cut with a cutter, and after curing and curing in an autoclave, the raw material slurry is poured into the molding frame (18),
Once the slurry is semi-hardened, it is cut into individual panel sizes using a cutter, cured and hardened in an autoclave, and then, if necessary, the end faces are cut to obtain ALC plates. .

(Problem to be Solved by the Invention) In manufacturing the ALC as described above, the reinforcing front basket (a) is correctly aligned and transferred to the alignment cart (14) on which the alignment jig (15) is lined up. This process is essential. However, since the reinforced forebasket (a) has a flexible structure, no means have been taken in the past to make it possible to quickly perform this process mechanically. On the other hand, it is extremely troublesome to do it manually, and as the production volume of ALC board increases, it is necessary to align, for example, - pieces of reinforcing forebaskets in a short time.
Not only is processing impossible at such high speeds, but it is also inefficient.

Therefore, in the ALC manufacturing process as described above, the present invention provides an alignment cart (14
) The object of the present invention is to provide a method and device for efficiently transferring and sequentially arranging items on an arranging table having a series of arranging guide rods as shown in FIG.

(Means for Solving the Problem) Therefore, the vertically placed reinforced front basket is guided by contacting the back plate and the torsion restraint guide on both main surfaces thereof, and is guided to the position directly above between the alignment guide bars of the alignment table. A method for transferring a reinforcing front basket to an alignment table has been constructed, which is characterized in that the reinforcing front basket is transferred, held and suspended by an elevating hand, and placed on an alignment table between alignment guide bars. Further, in the above-described transfer method, the reinforcing front basket, which has been carried in horizontally on a conveyor or the like, is engaged with a hook to stand up vertically.

The items that can be used for the above-mentioned transfer method include a lift hand that grasps and suspends the vertically placed reinforced front basket, a back plate that abuts and guides one main surface of the reinforced front basket, and a A torsion restraint guide that contacts and guides the other main surface of the basket, and a device that moves the lifting hand, back plate, and torsion restraint guide, and aligns the back plate and torsion restraint guide when lowering the reinforced front basket. A device for transferring a reinforcing front basket to a sorting table is configured, comprising a moving means for moving the reinforcing front basket to the top of the guide bar and lowering the elevating hand until the reinforcing front basket is placed on the sorting table. In addition to the lifting hand, back plate, torsional restraint guide, and transportation means as described above, a lifting device is provided which engages with a hook the reinforcing front basket, which has been carried in horizontally on a conveyor, etc., and raises it vertically. The equipped transfer equipment was constructed. Furthermore, the reinforcing front basket transfer device is constructed by providing a hook on the back plate for engaging and detaching from the reinforcing front basket.

The back plate used in the present invention is the one that first engages with the reinforced front basket, and is equipped with hooks that engage and disengage from the reinforced front basket, particularly a plurality of hooks that engage and disengage from the main bars of the reinforced front basket. Preferably. In addition, the torsional restraint guide used in the present invention holds the reinforced front basket engaged with the back plate between the back board and the torsional restraint guide so that the reinforced front basket does not shake even when moving at high speed. It is preferable that the reinforcing front basket be able to be rotated by 90 degrees with respect to the back plate so that the reinforcing front basket can be inserted or released.

It is preferable to use a plurality of each of these back plates and torsional restraint guides so as to sandwich one reinforcing front basket at multiple points, since this further improves stability.

Furthermore, the elevating hand used in the present invention is a device that is located between the above-mentioned back plate and the torsional restraint guide, and is used to grasp and raise/lower the reinforcing front basket. It is preferable to have a chunk that can be opened and closed, and in particular, it is preferably equipped with a plurality of lifting hands, so that a reinforcement cage of any length can be grasped at its plurality of spacer positions, and this It is particularly preferable that the reinforcing forebasket can be stably lowered while being held only by the elevating hand.

These back plates, torsion restraint guides, and lifting hands, in particular, the plurality of back plates, the plurality of torsion restraint guides, and the plurality of lifting hands are installed on a moving means, and the moving means is moved to the supply position of the reinforced forebasket (e.g. It is configured to be movable to a position near the reinforcing bar carry-in conveyor position) or above between arbitrary alignment guide bars on the alignment table on which the reinforcing front basket is to be placed.

Note that any transport means may be used to transport the reinforced front basket to the transfer device of the present invention, but - for boat fishing, a conveyor is preferable, and furthermore, the reinforced front basket may be placed horizontally on the conveyor. By laying it down, it can be transported stably. In addition,
In order to make it possible to guide the lying reinforcing bar cage between the back plate and the torsion guide, it is necessary to place the reinforcing bar vertically, that is, to raise it upright at 90 degrees, but there is no space for operating this raising device. In certain respects, it is particularly preferred that the loading means is a roller conveyor. When a roller type conveyor is used, if the roller has a large number of grooves for inserting the main reinforcing bars of the reinforcing bars, the reinforcing bars can be fed without bending.

In addition, regarding the relative positional relationship between the rollers and the reinforcing bar cage, it is recommended to carry the transfer device so that the side of the reinforcing bar cage, which will be the lower end when raised up, is always in a constant position. It is preferable to do so.

In addition, the reinforcing bar cage raising device engages with the main bar of the reinforcing bar cage.
A type in which a plate equipped with a plurality of detachable hooks rotates 90 degrees is suitable in combination with a roller type conveyor.

(Function) According to the method and device of the present invention as described above, the reinforcing bars are guided between the torsional restraint guide and the back plate up to the upper part between the alignment guide bars on the alignment table while being guided in the lateral direction (horizontal direction). ), it is possible to maintain its position even with the flexible structure of reinforcing bars and traverse at high speed. In addition, the reinforcing bars that have been sent above between the alignment guide bars on the alignment table descend to the top of the alignment guide bars while being guided between the torsion restraint guide and the back plate. Since it is held and suspended and placed between the alignment guide bars, it can be reliably inserted between the reinforcing bar alignment guide bars even if it is slightly twisted. In this way, high-speed processing becomes possible, and the reinforcing bars can be inserted at short intervals.

In addition, in the transfer device of the present invention, the torsion restraint guide holds the reinforcing bar cage between it and the back plate to prevent the reinforcing bar from shaking and enables high-speed movement. serves to ensure insertion between the alignment guide bars, and if the back plate has a hook that engages and disengages from the reinforcing bar, it grips the reinforcing bar in cooperation with the lifting hand.
