Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an alignment treatment with an alignment guide for aligning a plurality of reinforcing braces of a concrete product, for example, an autoclave-cured lightweight cellular concrete product (ALC) at regular intervals. It is an alignment jig attachment machine for mounting the tool on the alignment carriage.

(Prior art) As a conventional trolley for aligning and loading a reinforcing braces,
There is one disclosed in Japanese Utility Model Publication No. 1-20094. This is an alignment guide unit in which the alignment guides for aligning a plurality of reinforcing reinforcement baskets at regular intervals, and the alignment guides different in interval pitch from the alignment guides are common to the rotation axis, and are provided at 90 ° positions to each other. It is a reinforced basket cage alignment trolley that carries a large number of.

(Problems to be Solved by the Invention) In Japanese Utility Model Publication No. 1-20094, the alignment guide is fixed to the alignment carriage and cannot be easily removed.

For this reason, correspondence to different board thicknesses is limited to two types, and for other board thicknesses, another bogie must be prepared.

In addition, a spacer attached to the reinforcing bar cage is generally used to attach the reinforcing bar cage to a predetermined position in the form, but the reinforcing bar cage is relatively flexible. An alignment guide is needed near the. Nevertheless, the prior art has not taken any measures from this point of view, and it is practically difficult to cope with different plate thicknesses.

As described above, the conventional technique has many drawbacks when producing ALCs having different plate thicknesses.

Therefore, the inventors of the present invention use an alignment jig having alignment guides arranged in a line at a thickness interval of the reinforcement baskets, and according to the length of the reinforcement baskets on the carriage, the problem can be solved by installing them. I found that it would be resolved. With this configuration, the plate thickness of the ALC is different, so even if the thickness of the reinforcing bar cage is different, if you have an alignment jig with alignment guides lined up in a row at the thickness intervals of the reinforcing bar cage, It was also found that it is possible to deal with this problem, and by providing a fixed guide for a spacer on the alignment guide in only one horizontal row, the alignment guide can be provided in the vicinity of the spacer of the reinforcing bar cage.

However, when arranging the alignment jig at a predetermined position on this trolley according to the length of the reinforcing basket, mechanical accuracy is higher than manual operation, so the alignment jig is attached. The machine needs to be completed.

Therefore, the present inventors have completed the present invention in order to solve the problem by precisely moving the carriage and mounting the alignment jig on the carriage at a fixed position.

(Means for Solving the Problem) An alignment jig attaching machine according to the present invention relates to an alignment jig supply device, a gripping tool for grasping an alignment guide of the alignment jig, and a swing pin insertion hole of the alignment jig. An aligning jig attaching machine, comprising: an ascending / descending frame having a matching swinging pin, and a moving frame that supports the ascending / descending frame and moves in a direction perpendicular to a main surface thereof. Is characterized by having a chain conveyor with a top roller, a fixed stopper provided at the end of the chain conveyor, and a plurality of movement stoppers for alternately stopping and passing an alignment guide provided at a predetermined interval in front of the chain conveyor. It is a jig mounting machine. In addition, at the place where it hits the end of the moving range of the moving frame, the shock is absorbed by the shock absorber, and the starting point and the ending point of the movement are set at the place where the aligning jig of the aligning jig supply device is grasped and the aligning jig grasped. It is more preferable that the point is lowered toward the carriage.

Further, it is more preferable to provide a shock absorber for receiving the horizontal beam of the elevating frame to reduce the impact at the lower end of the elevating frame. If the pin provided at the tip is urged downward by a spring, the tip of the pin It is more preferable that even when the object hits an obstacle, a downward force is constantly applied.

(Operation) In the aligning jig attaching machine of the present invention, the moving frame moves the aligning jig of the aligning jig supplying device to a position where the grasped aligning jig is lowered toward the carriage, or vice versa. And the elevating frame is for lowering the alignment jig toward the carriage. The chuck claw also plays a role of holding the alignment guide of the alignment jig. However, if the alignment guide is only gripped by the chuck claws, the alignment guide may shake during movement, particularly when lowered. Since it is difficult to set the alignment guide at a predetermined position on the carriage when the alignment guide shakes, the device of the present invention is provided with a pin in order to stop the alignment guide swing at a position different from the chuck claw. There is.

As described above, the device jig attaching machine of the present invention grasps the tip of the alignment guide of the alignment jig at a predetermined position on the jig supply device with the chuck claws, and inserts it into the pin hole provided in the alignment jig. It is possible to position the alignment jig at a predetermined position of the alignment carriage while inserting the pin to prevent the alignment jig from swinging.

In the present invention, handling both sides of the alignment jig,
Moreover, since both sides of the alignment jig are fixed by the steady pin, the alignment jig does not shake back and forth even when the alignment jig is transferred at high speed.

Therefore, in order to set the reinforcing structure basket of the flexible structure to the correct position, it is necessary to have an alignment guide near the spacer of the reinforcing structure basket, but the rack is attached to the alignment carriage and Since there is a rack in the jig and the racks are in mesh with each other, it is possible to do so depending on the mounting position of the alignment jig.

However, in the jigs given in the examples, the rack pitch is generally set to 10 mm, but even in this case, it is necessary to engage with accuracy of ± 2 mm in order to engage at a predetermined position. , While increasing the positional accuracy of the carriage that is stopped to load the alignment jig, as in the present invention,
It is necessary to constantly attach the alignment jig with a constant accuracy so that the alignment jig is not displaced in the attachment position by the alignment jig attaching machine.

Further, in order to facilitate the assembly of the reinforcing bar cage, the reinforcing bar cage can be accurately positioned when the lower spacer and the fixed guide are in mesh with each other.

In any case, since the arrangement of the reinforcing braces is different for each form, it is necessary to set the mounting position of the alignment jig of the bogie for each bogie according to the arrangement of the reinforcing braces. That is possible.

(Effect of the Invention) According to the present invention, since the alignment guide of the alignment jig is gripped and the alignment jig is prevented from swinging, the alignment jig is set at a high speed. It can be accurately attached to the position, and the attachment position of the alignment jig on the trolley can be set for each trolley according to the arrangement of the reinforcing braces.

According to the second aspect of the invention, even if the aligning jigs are continuously flowed by the conveyor, it is possible to supply the aligning jigs one by one to the gripping position of the aligning jig attaching machine.
