Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for regulating the descent of panels in a panel shutter, and more specifically, it maintains the meshing state between a roller chain connecting five panels in the vertical direction and an induction brocket properly during the closing operation of the shutter. This invention relates to a panel descent regulating device that allows panels to always descend smoothly and reliably.

This type of panel shutter meshes the extra length of the roller chain connecting each panel in the downward direction with the guidance sprocket arranged on the left and right side plates of the shutter storage case connected to the upper end of the guide rail. Since it is configured to open and close the opening in the building in conjunction with the rotation of the induction sprocket, When the panel is lowered in the same plane during the shutter closing process, the entire load of the panel is applied to the roller chain, so as shown in Figure 5, the entire load of the panel is applied to the roller chain. The roller chain is always pulled in the downward direction of the panel, but only the load of the roller chain between C■ and C2 is applied in the B direction, so as a result, the roller chain on the storage side from the vertical center line is always pulled A force that pulls it in the A direction will work. For this reason, during the closing operation of the shutter, the roller chain lifts up from the induction sprocket, and the rollers that are locked in the troughs climb over the teeth, creating a so-called mountain-crossing phenomenon, which disrupts the left-right balance and causes the panel to become unbalanced. There were drawbacks such as the panel not being able to be lowered properly and, in some cases, the roller chain coming off the guide sprocket, making it impossible for the panel to lower.

In view of the above-mentioned circumstances, the present invention was devised in order to eliminate the drawbacks of the conventional technology. Then, the outer link plate is connected to the inner link plate by straddling the rollers located before and after the aperture shaft, and the lower edge is connected to the above-mentioned guide sprocket above the axis of the guide sprocket. By installing a roller chain holding plate that is curved along the rotational trajectory of the roller shaft so that it can be adjusted in the vertical direction, the phenomenon of the roller chain going over the peak of the guide sprocket or coming off from the guide sprocket, which conventionally occurs during the closing operation of the shutter, can be avoided by moving the roller shaft. This can be prevented by the cooperative action of the supporting outer link plate and the roller chain holding plate, and the proper engagement between the roller chain and the induction sprocket can be maintained, allowing the panel to always descend smoothly and reliably. The object of the present invention is to provide a device for regulating the descent of a panel in a panel shutter.

The above objects of the present invention will become more clear by describing the embodiments shown in the drawings.

That is, in FIGS. 1 to 5, reference numeral 1 denotes a panel shutter, and the panel shutter l is arranged at both ends of an upper stile 3 of a plurality of elongated panels 2 arranged at predetermined intervals in the vertical direction.

The extra length of the roller chain 6 is engaged with the induction sprocket 11. Reference numeral 12 denotes a storage rail arranged horizontally inside the left and right side plates 10 of the shutter storage case 9, and the storage rail 12 is connected to the roller shaft of each panel 2 that moves upward in conjunction with the rotation of the induction sprocket 11. Each panel 2 is
This is to guide the movement in the horizontal direction in a state in which the robots are lined up in parallel in sequence.

Reference numeral 13 denotes a roller chain holding plate disposed above the axis 11a of the induction sprocket 11, and its base 1
3a is attached to the top plate 14 of the shutter storage case 9,
The plate body 13b is fixed to the base 13a via a long groove 13c so as to be adjustable in the vertical direction, and the lower edge 13 of the plate body 13b
d is curved along the rotation locus of the induction subrocket l1.

Next, the operation of the present invention constructed as described above will be explained. Now, when an opening signal is issued to the panel shutter 1 that closes the opening of the building, a driving sprocket connected to an opening/closing machine (not shown) rotates, and in conjunction with this rotation, the guiding sprocket 11 moves to the fifth position. In the process of being rotated in the direction of arrow B shown in the figure, each panel 2 connected by the roller chain 6 moves upward along the guide rail 8 and is moved along the rotation locus of the guiding sprocket 11.
The direction of movement is gradually changed from the ascending direction to the horizontal direction, and when the roller 7 passes directly above the axis 11a of the induction sprocket 11, the roller 7, which is supported on the roller shaft 5, is attached to the storage rail 12 of the shutter storage case 9. With the transfer of the rollers 7, the panels 2 are moved and guided in the horizontal direction and stored in a state where they are lined up parallel to each other. On the other hand, when closing the panel shutter 1, the induction sprocket 11 is rotated in the direction of arrow A shown in FIG. The roller shaft 5 of the panel 2 located in the front row is aligned with the shaft center 11a of the induction sprocket 11.
When the roller shaft 5 passes directly above the guide sprocket 1, the direction of movement is changed from the lateral direction to the descending direction, and the roller shaft 5 is moved directly above the induction sprocket 1.
In the process of being moved along the rotational trajectory of 1, it descends and is sequentially placed on the same plane while being supported by the guide rail 8,
The opening in the building is thus closed.

When the induction sprocket 11 is rotated in the A direction in the process of the closing operation as described above, the entire load of the panel 2 is applied to the roller chain 6. is always pulled in the direction of descent of panel 2 in the A direction, but in the B direction 01~
Since only the load of the roller chain 6 between C2 and C2 is applied, the roller chain 6 meshing with the rotation locus in the descending direction of the panel 2 from just above the axis 11a of the induction sprocket 11 is pulled in the descending direction of the panel 2. However, the roller chain 6 between 01 and C2 lifts up from the induction sprocket 11 and comes off.

However, in the present invention, the roller shaft 5 is attached to the mounting position of the roller 6a of the roller chain 6 by penetrating the center of the outer link plate 6b, and the outer link plate 6b is positioned before and after the roller shaft 5. roller 6a,
6b and connected to the inner link plate 6c, and above the axis of the induction sprocket 11 is provided a roller chain presser plate 13 whose lower end edge is curved along the rotation locus of the induction sprocket l1. 5 is a roller 6a located before and after the outer link plate 6b.
, 6a are integrally meshed with the induction sprocket 11, so that their lifting is prevented and there is no risk of them coming off. Therefore, when the panel shutter 1 is closed, the engagement between the roller chain 6 and the guiding sprocket 11 is always maintained properly, and the panel 2 is lowered smoothly and reliably.

In short, the present invention provides for attaching the roller shaft that supports the panel through the center of the outer link plate to the roller mounting position of the roller chain, and attaching the outer link plate to the rollers located before and after the roller shaft. Conventionally, a roller chain presser plate is attached above the axis of the guide sprocket and is vertically adjustable and has a lower edge curved along the rotation locus of the guide sprocket. The outer link plate that supports the roller shaft and the roller chain press plate prevent the roller chain from going over the mountain or coming off from the induction subrocket that occurs during the closing operation of the shutter. This has the extremely useful practical effect of maintaining a proper meshing state between the guide sprocket and the guide sprocket, and ensuring that the panel always descends smoothly and reliably.
