Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a plurality of motors connected in a series at predetermined intervals in the vertical direction via a chain chain, and which move up and down along a vertical guide rail. A panel joint in a panel shutter in which the panel bodies are sequentially transmitted to the horizontal storage rail side provided above the guide rail through a transmission sprocket that engages with a chain chain and stored in parallel. This relates to a sending device.

[Prior art and problems to be solved by the invention] Conventionally,
The panel body of this type of panel shutter is
A chain chain connected to the upper edges of both left and right ends of the panel body is hoisted up by the rotation of the transfer sprocket, and rises to the upper extension line of the guide rail, and then moves laterally along the circumference of the transfer sprocket. Since the chain connection part on the top of the panel body engages with the transfer sprocket, it changes from vertical transfer to horizontal transfer along the circumference of the transfer sprocket. It turns out. However, in the past, the panel body was transferred from the transfer sprocket to the storage rail side at approximately the top of the transfer sprocket, so the chain chain had a substantially effective engagement area with the transfer sprocket and the transfer sprocket. It only extends from the top position to the guide rail side,
As a result, there is a problem of chain tooth skipping, which impairs reliable conveyance.

[Means for Solving the Problems] The present invention has been devised in order to eliminate these drawbacks in view of the above-mentioned actual situation. A plurality of panel bodies are connected to each other and move up and down along the vertical guide rail, and are sequentially transferred to the horizontal storage rail provided above the guide rail via a transfer sprocket that meshes with the chain chain. In the panel shutter, which is arranged to be stored in parallel, the panel body is transferred to the storage rail side of the transfer sprocket at a low position on the storage rail side beyond the top of the transfer sprocket. It is an object of the present invention to provide a panel relay device for a panel shutter characterized by the following.

[Example] The structure of the present invention will be described based on an example shown in the drawings. Reference numeral 1 denotes a panel shutter provided at an opening of a building, and the panel shutter 1 is arranged at predetermined intervals in the vertical direction. It is constructed by connecting and pivotally supporting a plurality of panel bodies 2 arranged in series to a chain chain 4 via connecting members 3 disposed on the upper side of both left and right ends thereof. Each panel body 2 is formed into a long plate shape that is long in the horizontal direction, and a protruding strip 2a is formed on the upper edge thereof over the entire length in the longitudinal direction, and a protruding strip 2a is tightly fitted on the lower edge. A groove 2b is formed. Guide rails 5 are provided vertically on both left and right edges of the opening, and the panel shutter 1 is guided by the guide rails 5 to move up and down. A storage case 6 is provided above the guide rail 5. Inside the storage case 6, there are storage rails 6 facing horizontally and laterally.
A is installed.

Reference numeral 7 denotes a transfer sprocket disposed above the upper end of the guide rail 5, and the transfer sprocket 7 is supported in a cantilevered manner on a drive shaft 7a that rotates forward and backward by a drive mechanism (not shown). Chain chain 4 meshing with transfer sprocket 7
By winding up or down the panel shutter 1, the panel shutter 1 is raised and lowered. The transfer sprocket 7 located above the guide rail 5 is provided with an extension rail 8 that is inclined so as to be located closer to the storage rail 6a than on the upper extension line of the guide rail 5, and the extension sprocket 7 is provided with an extension rail 8 that is inclined so as to be located closer to the storage rail 6a than on the upper extension line of the guide rail 5. It is adapted to mesh with the connecting member 3 at a position biased toward the side 6a. The panel body 2 that has risen along the diagonal transfer path in this way is transferred to the storage rail 6a side by the transfer sprocket 7, but in this case, a The traveling rollers 9 that have been moved are placed on the side of the storage rail 6a beyond the top of the transfer sprocket 7 at a position lower than the top of the storage rail 6a.
It is now being forwarded to.

Next, the operation of the present invention constructed as described above will be explained. First, in the opening operation of the panel shutter 1, by rotating the transfer sprocket 7 and winding up the chain chain 4, the panel bodies 2 arranged in series in the vertical direction are successively raised in a series starting from the uppermost one.

This is done by being conveyed from the guide rail 5 via the extension rail 8 to the storage rail 6a side and stored in the storage case 6 in parallel in the horizontal direction. On the other hand, panel shutter 1
The closing operation is performed by rotating the transfer sprocket 7 in the opposite direction and winding down the chain chain 4, so that the chain chain 4 is transferred from the storage rail 6a to the guide rail 5 side in the reverse operation.

At this time, the upper panel body 2 is attached to the ridge 2a of the lower panel body 2.
By tightly fitting the concave grooves, the panel shutter 1 is closed without any gaps.

In this series of opening and closing operations, the transfer sprocket 7
The panel body 2 rises by the rotation of.

On the side of the storage rail 6a beyond the top of the transfer sprocket 7, the running roller 9 is at a position lower than the top of the storage rail 6.
It will be transferred by rolling a.

Therefore, the chain chain 4 substantially effectively meshes with the transfer sprocket 7 on the side of the storage rail 6a, and the meshing area of the chain chain 4 is wide on both sides, sandwiching the top of the transfer sprocket 7. Therefore, the phenomenon of tooth skipping of the chain can be effectively prevented. As a result, the panel body 2 can be opened and closed reliably and smoothly without the tooth skipping phenomenon.

[Operations and Effects] In summary, the present invention is configured as described above, so that the substantially effective meshing area of the chain chain with the transfer sprocket is located between the top of the transfer sprocket and the guide rail side. It is ensured widely over both sides of the rail, and therefore the phenomenon of tooth skipping of the chain chain is effectively prevented and smooth and reliable opening/closing operations can be performed.

Claims (1)

[Claims] A plurality of panel bodies are connected in a series at predetermined intervals in the vertical direction via a chain chain and move up and down along a vertical guide rail, and are guided via a transfer sprocket that meshes with the chain chain. In a panel shutter that is sequentially transferred to the horizontal storage rail side provided above the rail and stored in parallel, the position of the panel body transfer to the storage rail side of the transfer sprocket is determined by the transfer sprocket. A panel transfer device for a panel shutter, characterized in that the transfer is carried out at a low position on the storage rail side beyond the top of the panel shutter.
