Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a turnbuckle conveying device that is capable of efficiently transporting turnbuckles by attaching a running tool to an endless string to suspend turnbuckles.

[Background technology]

For example, in buildings using dry construction methods, the walls,
Architectural panels used as floors, etc. are formed by attaching face materials s to the front and back sides of a frame F made of, for example, channel-shaped materials joined into a rectangular shape, as shown in Fig. 6. , Such architectural panels need to be held under pressure to cure the adhesive after the facing material s is attached.

Conventionally, for this type of curing, panels are stacked on top of each other and then compressed using turnbuckles.
On the other hand, in manufacturing such panels, in order to cure them, it is necessary to cure them by assembly line operations in order to streamline production. Must be returned to its installation location. In the conventional case,
Since an appropriate number of turnbuckles were stored and then returned using a push cart or the like, it was time-consuming to return them and the work efficiency was poor.

7 is selected and carried in by the feeding device 44.

The feeding device 44 is driven by encoder control, and the position of each lower plate 4 from the upstream end a is controlled.
The upper plates 4 are sequentially fed in from the vicinity of the downstream end b so as to be adjacent to each other.

The panel P is cured while moving on the rails 5, 6, and 7, and after curing, the feeding device 44 feeds the lower plate 4 to the third traversing table 11. The third transverse table 1
1 is moved to the downstream end b of the rail 6. A suspension position A for the turnbuckle conveying device 2 is provided at the downstream end b, and the turnbuckles T are removed and a set of three is suspended from the blades 26. The traveling tool 24 is sequentially stopped at the hanging position A and the removal position B by the micro switch LS2, and is intermittently stopped at one pitch by hanging at the hanging position A and removing the turnbuckle T at the removal position B. I can drive one by one. It can also be rotated continuously.

After that, the upper plate removal device 17 removes the upper plate 3 and places it on the upper conveyor 60 of the return conveyor 15,
Return top plate 3. Further, the lower plate 4 is transferred to the rail 116 by the fourth traverse table 12, and the unloading machine 21 sequentially places the panels P on the carry-out conveyor 114. The empty lower plate 4 is transferred to the lower conveyor 61 of the return conveyor 15 by the fourth traverse table 12, returns to the upstream end a, and is transferred to the loading machine 20 by the second traverse table 10. By repeating the same operation when the turnbuckles are brought in, the panels can be cured smoothly, and the turnbuckles can be sequentially circulated, increasing the efficiency of their installation and removal.
