Description

The present invention relates to a duct manufacturing apparatus including a duct forming machine, a transfer table, and a decoiler.

Duct forming machine having a duct forming means for spirally winding a metal strip to form a cylindrical duct, and a control box section incorporating a control means for driving and controlling the duct forming means, and a duct forming means 2. Description of the Related Art A duct manufacturing apparatus including a transfer table for rotatably supporting a duct fed from a container and a decoiler for feeding a metal strip to a duct forming means is well known in the related art. In a general duct forming machine, a control box portion is fixed to a side surface of a base supporting duct forming means.

In such a configuration, when ducts are to be installed on each floor of a high-rise building, the ducts are manufactured in advance by the duct manufacturing apparatus, and the manufactured ducts are transferred to a construction site of the high-rise building, and are used for work of the high-rise building. It is common to carry in each floor by an elevator (or a construction lift) and to attach it.

By the way, since the working elevator has dimensional restrictions, it is necessary to manufacture ducts in advance in a size that can be stored in the working elevator, and connect these short ducts on each floor. However, in a high-rise building having a large floor area, a large number of short ducts must be carried in, and the sequential connection of these ducts results in a lot of time loss and a cost increase.

Therefore, the inventor of the present invention came up with a new and novel idea of using a work elevator to carry a duct manufacturing device to each floor of a high-rise building and manufacturing the duct on the spot. By adopting such a configuration, it is possible to manufacture a long duct because there is no dimensional limitation at the time of duct manufacturing, and a complicated work of carrying in a short duct many times by a working elevator, and a small and small work. It is possible to omit the operation of connecting a simple duct. As a result, the efficiency of duct installation work in a high-rise building with a large floor area is dramatically improved, and a significant cost reduction can be realized.

However, in order to accurately and stably produce a duct of a required size, a duct forming machine, a transfer table, and a decoiler need to be strictly arranged at a predetermined operation position, which requires a considerable amount of time for installation work.・ Effort is spent. Therefore, every time the duct manufacturing apparatus is carried into each floor, if a high-level installation work is required, the work efficiency will eventually decrease. In addition, since the working elevator has a dimensional limit as described above, a dimensional problem may occur when the duct forming machine is stored in the working elevator.

Therefore, an object of the present invention is to provide a duct manufacturing apparatus that can simplify installation work and can quickly install a duct.

The present invention provides a duct forming machine having a duct forming means for forming a cylindrical duct by spirally winding a metal strip plate, and a control box section incorporating a control means for driving and controlling the duct forming means. And a molding machine support on which the duct molding machine is mounted, a transfer table for rotatably supporting the duct sent out from the duct forming means, a table support on which the transfer table is mounted, and an end portion made of metal. A first specified connection for detachably connecting the strip plate to a decoiler for feeding the duct forming means and a forming machine support base, and for connecting the decoiler and the duct forming machine at a specified position so that the separation distance is a specified value. A member and an end are detachably connected to the molding machine support table and the table support table, respectively, and the duct molding machine and the transfer table are position-defined and connected so that the separation distance becomes a specified value. The relative positional relationship between the duct forming machine, the transfer table, and the decoiler, which is in a connected state via the first prescribed connecting member and the second prescribed connecting member, makes it possible to produce a desired duct. A duct manufacturing apparatus to be a proper operating position to obtain, a duct forming machine, one end of a flexible arm having a plurality of rotating arms rotatably connected to each other is connected, and the other end of the flexible arm The control box section of the duct molding machine is connected rotatably, and the molding machine support on which the duct molding machine is mounted can be stored in the working elevator of the building where the duct is to be installed with the flexible arm folded. It is a duct manufacturing apparatus characterized by having various dimensions.

By the way, the duct forming machine of the conventional configuration had a configuration in which the control box portion was fixed to the side surface of the base as described above, so that the overall configuration was wide. By folding the arm, the control box can be positioned above the duct molding machine, and the width of the duct molding machine can be reduced. Therefore, it becomes possible to store the duct forming machine in the working elevator and carry it into each floor of the building using the working elevator. Furthermore, even if the connection state of the decoiler, the duct forming machine, and the transfer table is once released, if the connection is made again via the first specified connecting member and the second specified connecting member, the decoiler and the duct forming machine are always provided. The machine and the transfer table are placed in the operating position while maintaining a predetermined separation distance, so when installing the duct manufacturing equipment, reproducibility is created, and the duct manufacturing equipment can be quickly installed on each floor of the high-rise building. It becomes possible.

Here, there has been proposed a configuration in which a molding machine support on which a duct molding machine is mounted has a dimension capable of being stored in a space having a width of 5 m, a depth of 1.5 m, and a height of 2.2 m with the flexible arm folded. You. With this configuration, the duct forming machine can be carried into each floor of a high-rise building using a work elevator having a width of 5 m, a depth of 1.5 m, and a height of 2.2 m.

In addition, a plurality of transfer tables are provided, the ends of each of which are detachably connected to the table support, and the transfer tables are position-defined and connected so that the distance between the transfer tables becomes a specified value. A configuration including a three-point connecting member is proposed.

っ て も Even in such a configuration, it is possible to easily set the separation distance of each transfer table to a specified value by connecting the third specified connecting member and the table support respectively. For this reason, it becomes possible to quickly install a duct manufacturing apparatus on each floor of a high-rise building.

According to the present invention, the relative positional relationship between the duct forming machine, the transfer table, and the decoiler connected via the first specified connecting member and the second specified connecting member is a proper operation position at which a desired duct can be manufactured. A duct forming apparatus, one end of a flexible arm is connected to the duct forming machine, and the control box section of the duct forming machine is rotatably connected to the other end of the flexible arm, and the duct forming machine is Since the mounted molding machine support base has a size that can be stored in the working elevator with the flexible arm folded, it is possible to fold the flexible arm and position the control box section above the duct molding machine. This makes it possible to reduce the width of the duct forming machine. Therefore, it becomes possible to store the duct forming machine in the working elevator and carry it into each floor of the building using the working elevator. In addition, even if the connection state of the decoiler, the duct forming machine, and the transfer table is once released, if the connection is again performed via the first specified connecting member and the second specified connecting member, the decoiler, the duct forming machine, and the transfer table are always transferred. Since the table is arranged at the operating position while maintaining the predetermined separation distance, reproducibility is generated when installing the duct manufacturing apparatus, and the duct manufacturing apparatus can be quickly installed on each floor of the high-rise building. As a result, it is possible to manufacture a long duct without being limited by dimensions, and it is possible to omit a duct loading operation, a connecting operation, and the like, and to obtain an excellent effect of dramatically improving the efficiency of the duct mounting operation. is there.

Also, if the molding machine support on which the duct molding machine is mounted has a configuration that can be stored in a space with a width of 5 m, a depth of 1.5 m, and a height of 2.2 m with the flexible arm folded, It is possible to carry a duct forming machine to each floor of a high-rise building using a work elevator with a width of 5 m, a depth of 1.5 m and a height of 2.2 m.

In addition, in the case where a configuration is provided that includes a third specified connecting member that positions and connects a plurality of transfer tables to each other, the separation distance between the transfer tables can be easily set to the specified value. For this reason, it becomes possible to quickly install a duct manufacturing apparatus on each floor of a high-rise building.
