1 is a plan view of a shutter manufacturing apparatus according to the present invention. The shutter manufacturing apparatus includes a roll forming machine 1 for forming a sheet-shaped steel material unwound by an uncoiler (not shown) into a predetermined cross-sectional shape, and a shutter formed by cutting the steel material formed by the roll forming machine into a predetermined length. Cutting machine 2 as member 4 and shutter member 4
Is assembled as a shutter, and a conveying means (not shown) for conveying the shutter members from the cutting machine to the assembling section 3 one by one.

In the assembly section, by the transport means,
When the first (first) shutter member 4 is carried in, it is moved by one pitch in the width direction (downward in FIG. 1), both ends of the member are clamped, and the punching machine 5 is used for mounting the core drum. A hole is made. The second shutter member is loaded into the assembly section while the first shutter member completes the one pitch transfer and is clamped and punched at both ends. The second shutter member is
When being carried into the assembly section, the engaging portion formed therein is inserted into the engaging portion of the waiting first shutter member, and when the carrying-in of the second shutter member is completed, the first And the second shutter member is engaged and combined with each other. In this state, the combined first and second shutter members are moved by one pitch in the width direction, and stand by until the third shutter member is loaded. The same process is repeated until a predetermined number of shutter members (required to configure the shutter) are loaded.

In this way, the shutter member is transferred in the width direction for each pitch while being assembled, and is discharged from the shutter member discharge end of the assembly section. In the present invention, this discharged shutter member is immediately discharged. The winding drum 7 is wound up.

That is, the assembly section 3 has three horizontal guide rails 6 provided at predetermined intervals in the lengthwise direction of the shutter member and extending to the discharge end of the shutter member, and is assembled. It is designed to support both end portions and a central portion of the transferred shutter member, and the guide rail 6 is provided with a concave curved portion 6'as shown in FIG. Has been
The core drum 7 is set above the tip. That is, at the positions on both sides of the core drum 7 which are set to this position, cones 8 and 8'for engaging both end portions of the drum and fixing and holding the core drum, and the cones are provided. The core drum 7 is pressed toward the end of the core drum.

It is mounted on the frame of the assembly section so as to be movable in the length direction of the core drum, and the core drum 7 having a length corresponding to the shutter width can be fixed and held. Also, although the motor 10 is not shown in detail,
An endless chain is hung between the cone 8 and the cone 8 to rotate and drive the core drum 7
Is designed to rotate.

When the assembled shutter member discharged to the curved portion 6'has a certain length, the first shutter member is manually lifted and screwed to the core drum 7. When screwing, as shown in FIG. 2, the screwed and assembled shutter members form a loop 4 '. And
In this state, the motor 10 is driven to wind up the shutter member. As shown in FIG. 2, two sensors 11 and 12 are provided at predetermined intervals in the vertical direction in a region where the loop 4 ′ is formed above the curved portion 6 ′, and a loop is formed between both sensors. Whether or not it exists, the loop 4 ′ always drives the motor 10 so that this area exists. That is, the continuous drive of the motor 10 does not interfere with the intermittent transfer movement of the shutter member assembled and ejected from the assembly section.

In the illustrated example, the shutter member is attached to the winding core 7 by hand, but a guide for guiding the assembled shutter member to the drum 7 is provided and the first shutter member is attached to the drum. A means for supplying a screw for fixing to 7 and a screw stopper for screwing the first shutter member to the drum 7 by the supplied screw are provided to automatically guide the guided first shutter member. You can also use a screw.
