In the guide device 18, when the long hose 10a is sent out by the sending device 16, the frame 6
0 is in the ascending position, and the side plate 48 is in the approaching position. The side plate 48 and the support base 46 constitute a cylindrical guide space 52, and the long hose 10a sent out is supported by the support base 46. Performs forward guidance while supporting on the upper surface.

When a chuck for the long hose 10a becomes necessary, the side plate 48 is opened and the frame 60 is lowered to release the surrounding of the long hose 10a.
That is, the long hose 10a is exposed on the support base 46.

When ascending and descending with the side plate 48 open,
Guidance is performed by guide rollers 64 shown in FIGS.

As shown in FIG. 7, near the front end of the support base 46 and the side plate 48, a stopper device 66 for stopping the feeding when the long hose 10a is fed by a predetermined amount is provided. I have.

[0027] The stopper device 66 comprises a pin 68 which is inserted inside the end of the long hose 10a as shown in FIGS. 7 and 8, the abutment portion 70 to abut the long hose 10a front end , A moving member 72 that holds and moves these members, a cylinder 74 that drives the moving members 72 to move forward and backward, and a guide rod 76 that guides movement at that time.

The moving member 72 also has a first sensor 78.
And a second sensor 80 are provided. The first sensor 78 detects the arrival of the front end of the long hose 10a and reduces the feed speed of the sending device 16;
0 indicates the sending device 16 by detecting the front end of the long hose 10a.
Is to completely stop feeding.

The stopper device 66 is provided with the long hose 10.
The feeding of a after stopping, to retract the moving member 72 to the left in FIG. 7 by the cylinder 74, the pin 68 Nagashakuho
Is detached from the inside of the base 10a.

As shown in FIGS. 2 and 3, the bending and deforming device 20 includes a first gripper fixed in a horizontal direction.
A click 22 is held by the slider 84, the position in the horizontal direction and a second gripping chuck 23 of the variable with this.

As shown in FIG. 4, the gripping chucks 22 and 23 are provided on a corresponding pair of elevating members 88.
The lifting cylinder 90 moves up and down together with the lifting body 88.

The holding chucks 22 and 23, the elevating body 88 and the elevating cylinder 90 are held by a holding plate 92.

A guide member 94 is fixed to the holding plate 92. The guide member 94 and a guide rail 96 on the side of the elevating body 88 fitted to the guide member 94 act so that the elevating body 88 is guided up and down. It has become.

The holding plate 92 on the first gripping chuck 22 side is provided with a rotary drive cylinder 10 provided on a fixed member.
4 (Rotating device) is connected (see FIGS. 3 and 4) .
The holding plate 92 on the side of the second gripping chuck 23 has a rotary drive cylinder 104 (rotating device) provided on the slider 84.
Are connected to each other.

These cylinders 104 hold the holding plate 9
2 for rotating the elevating body 88 held by the holding plate 92 around the axis 97 by 90 degrees.

The slider 84 for holding the holding plate 92 on the side of the second gripping chuck 23 is screwed to a screw shaft 98, and is driven by a motor 100 shown in FIG.
2 rotates under the guidance of the guide rail 102 with the rotation of FIG.
3 and in the left-right direction in FIG. That is, in this example, the slider 84, the screw shaft 98,
The motor 100 and the guide rail 102 are
This constitutes a means for moving the hook 23.

As shown in FIG. 9, the delivery device 25 includes a slider 106 that moves in the horizontal direction, a cylinder 108 that drives the slider 106, and a guide rod 110 that guides the movement.

The slider 106 suspends a pair of chucks 112, and these chucks 112 can be moved up and down by a cylinder 114 provided on the slider 106.

On the other hand, the conveyor device 26 has a conveyor chain 116 as shown in FIG. The conveyor chain 116 is provided with a number of holding chucks 28 arranged at regular intervals.
16 and can be intermittently moved at regular intervals .

Next, the operation of the present apparatus will be described. As shown in FIG. 1, the long hose 10a is sent out from one end side at a predetermined speed by the feeding device 16 from a state wound in a coil shape.

At this time, the guide by the guide device 18 is performed, and no tension is applied to the end of the hose.
The long hose 10a is smoothly sent out.

When the front end of the advancing elongated hose 10a reaches a predetermined position, the first sensor 78 in the stopper device 66
When this is detected, the feeding speed of the sending device 16 is reduced, and when the front end of the hose is next detected by the second sensor 80, the feeding motion of the sending device 16 stops.

At this time, the contact member 70 of the stopper device 66 comes in contact with the end surface of the hose, and the pin 68 is fitted inside the hose. Then, the contact member 70 and the pin 68 are retracted by the cylinder 74, Detach from the end.

At the same time, the pair of side plates 48 of the guide device 18 move away from each other and descend as shown in FIG. 6B, exposing the long hose 10a on the support base 46.

Then, a pair of grippers of the bending deformation device 20
Tsu and click 22 is lowered to grip it a long hose 10a at a constant distance apart two locations, specifically, the second gripping Ji
The jack 23 is a predetermined length from the front end of the long hose 10a.
Hold this at the point where the free end is left, and
The chuck 22 is separated from the second gripping chuck 23 by a certain distance.
Grasp at the place where it was set. Next, the cutting blade 40 of the cutter 24
By cutting a long hose 10a by a predetermined length portion but advances
A hose 10 having a predetermined length is obtained. At this time, the hose 10
The rear end of the first
Are held by the holding chuck 22.

Subsequently, the movable second handle of the bending / deforming device 20 is used.
The holding chuck 23 moves in the horizontal direction by the movement of the slider 84, and moves closer to the first holding chuck 22.

At this time, the cylinder 104 shown in FIG.
Operates to change the direction of gripping with respect to the end of the hose 10 by 90 degrees. That is, the axis of the front end of the hose 10 is
The gripping chucks 22 and 2 are oriented so that the axes are parallel to each other.
Change the direction of 3.

[0048] Thus the hose 10 is bent and deformed in U-shape, each end close to a certain distance while oriented in the same direction, before
The end and the rear end are aligned side by side and parallel at regular intervals.
I'll make it straight.

Thereafter, the delivery device 25 is connected to the bending deformation device 20.
The holding chuck 22, 23 both ends of the hose 10 which is gripped by horizontal movement received respectively by which the conveyor next to each other 26 two holding chuck 28,
Hand over to 28 .

The conveyor device 26, which has received the hose 10 in a U-shaped bending deformation state, conveys the hose 10 along a predetermined conveyance path, and on the conveyance path, the marking device 30, the metal fitting insertion device 32, and the caulking device 34. Both hoses 10
End marking process, to free ends of both ends of hose 10
Connection fitting insertion process, <br/> caulking process of the inserted fitting 12, 12 (fixing treatment) is performed. In addition, connection fitting insertion
Processing is performed manually by the operator before swaging
You may do it.

At the end of the conveyor device 26, the connection
The unloading device 36 receives the hose 10 to which the metal fitting 12 is fixed from the conveyor device 26 and discharges it to the outside or delivers it to a subsequent process.

Although the embodiment of the present invention has been described in detail, this is merely an example, and the present invention can be configured in a form in which various modifications are made based on the knowledge of those skilled in the art without departing from the gist of the present invention. is there.
