When the air of the blower 41 is ejected from the air pipe 42 into the through hole T, it is possible to securely attach the outer skin P by the base 20, but because of the flexible property of the outer skin P, So that it is possible to ensure maximization of workability by blocking the process failure by previously pressing the cover P as the elevating cover module 60 in the present invention.

More specifically, the lift module 60 includes a lift pneumatic cylinder 61 mounted on the supporter 10a and a lift cover 62 raised and lowered according to the driving of the lift pneumatic cylinder 61.

The elevating cover 62 is moved up and down by the elevating and pneumatic cylinder 61 so that the phenomenon that the middle point of the envelope P unexpectedly rises when the air is blown through the air pipe 42 can be prevented in advance.

8A and 8B are enlarged perspective views showing the operation of a screw bundle constituting a compressor for a flexible duct according to the present invention.

8A and 8B, the lifting height of the lifting cover 62 is fixed to the supporter 10a, and the lifting height of the lifting cover 62 is adjusted to the height of the screw bundle 70 to be adjustable in accordance with the diameter of the through- So that they can be interlocked.

When the flexible duct is installed in a building, a house or a building, the diameter of the duct may be large or small depending on the surrounding environment. In this case, the through hole (T) of the envelope P is also inevitably large and small. According to the present invention, the height of the lifting and lowering cover 62 can be adjusted as a screw bundle 70 in accordance with the size of the housing P, that is, the diameter of the through hole T.

7A and 7D, the elevating cover module 60 advances the moving car 50 in a state where the elevating cover 62 is lowered to push the end of the casing P to the starting end, The hinge 64 is fixed to the first end of the supporter 10a so that the compression shell P1 can be gripped and removed when the hood P1 is provided. (63).

An air pipe 42 provided at one side of the frame 10 is positioned at the initial end of the supporter 10a and the starting end of the outer covering P is clamped with respect to the air pipe 42, The end of the envelope P is pushed and made into the compression envelope P1 by the air pipe 42. In the present invention, when the starting end of the envelope P is clamped to the air pipe 42, And maintains the closed state when air is ejected from the air pipe 42.

The outer casing of the flexible duct according to the present invention is mounted on one side of the supporter 10a to tighten the outer casing P from the left and right when the starting end of the outer casing P is fitted into the air pipe 42, And a clamping module 90 for releasing the tightening when the compression envelope P1 is provided by advancement of the compression sheath P1.

Since the envelope P can be blown when air is ejected from the air pipe 42 into the through hole T, the clamping module 90 can be directly gripped by the hand, So that the workability can be further improved.

The outer shell compression apparatus for a flexible duct according to the present invention may further include a pushing plate 80 mounted on one side of the supporter 10a to push out the compression shell P1 when the clamping module is released from tightening.

It is considered that when the moving car 50 advances and the outer skin P is compressed while being fitted to the air pipe 42, it may be difficult to remove the compression skin P1 by coming into close contact with the air pipe 42 due to its flexible nature In the present invention, the pushing plate 80 pushes the compression sheath P1 out of the air pipe 42 more quickly and easily.

The air pumping module 40 ejects air when the starting end of the outer sheath P is inserted into the air pipe 42 and is tightened by the clamping module 90 from the left and right so as to extend from the start end to the end end of the outer sheath P. Thereby allowing the air ejection to be stopped when the moving car 50 advances, while extending the through hole T.

When the air is continuously ejected from the air pipe 42, not only the compression of the envelope P becomes relatively difficult while advancing the moving car 50, but also the resistance against the advancing of the moving car 50 is retarded Therefore, in the present invention, air blowing for expanding the through hole (T) and air blocking for compressing the jacket (P) are alternately performed, thereby realizing productivity improvement by ensuring workability.

At this time, the ejection of the air from the air pipe 42 and the interruption of the air are not shown but can be realized by a timer for on / off of the blower 41 or an on-off sensor or the like adapted to the operation of the moving car 50 Of course.

The clamping module 90 includes a clamping pneumatic cylinder 91 fixed to one side of the supporter 10a and provided on the left and right sides of the air pipe 42 and a clamping pneumatic cylinder 91 mounted on the clamping pneumatic cylinder 91, And a clamp 92 that tightens from the left and right when the end is fitted into the air pipe 42. [

The clamp 92 can be operated through the clamping pneumatic cylinder 91 when the air pipe 42 is to be unfastened or released from the starting end of the envelope P. This makes it possible to enjoy both fastness and firm tightness.

The moving car 50 includes an moving pipe 51 fitted into the through hole T of the casing P and a moving plate 52 fixed to the moving pipe 51 to push the end of the casing P. ).

The moving pipe 51 can be inserted into the through hole T of the casing P. This makes it possible to compress the casing P more stably and the through hole T The compression process of the outer skin P can be realized without defects by pushing the end of the outer skin P so as to cover the diameter of the outer skin P.

Preferably, the moving car 50 includes a discharge hole 51a and an ice plate 52, which are opened in the moving pipe 51, so as to discharge the air filled in the through hole T of the casing P during forward movement, As shown in FIG.

All of the air filled in the through hole T must escape everywhere when the moving car 50 advances while the through hole T of the casing P is extended. In the present invention, The discharge port 52a is opened through the discharge hole 51a and the moving plate 52 so that the compression of the envelope P can be carried out rapidly. It is preferable to clamp the cover P as the clamping module 90 to allow the air to escape forward and backward when compressing the shell P so as to further minimize the resistance of the air.

The moving pipe 51 is inserted into the air pipe 42 when the compression casing P1 is provided by advancing the moving car 50 so that the length of the air pipe 42 and the length of the moving pipe 51 So that the compression of the outer skin P can be made more tight and the overall compression length of the compression shell P1 can be further reduced so that the convenience in the subsequent steps can be relatively improved .
