A pair of guides 19 for guiding a pipe cut out from the rack shelf 6 is disposed on the upper surface of the lifting beam 15 at a predetermined interval in a direction orthogonal to the lifting beam 15. An arm 20 for receiving a tube rolling on the guide 19 is protruded below the guide 19, and a recess 21 for temporarily receiving the received tube is formed at the tip of the arm 20. I have.

As shown in FIG. 1, a sizing and cutting device 3 is provided in front of the lifting and lowering type tube transferring device 8, and the sizing and cutting device 3 includes a tube sizing device 22 and a tube sizing device. It comprises a tube cutting device 23 arranged at the end of the dimensioning device 22.

The tube sizing device 22 has a plurality of rollers 25 for supporting a tube linearly arranged in the longitudinal direction of the gantry 24 on a gantry 24 arranged in parallel with the longitudinal direction of the rack shelf 6. At the same time, a traveling rail 26 is laid on the side of the roller 25 along the longitudinal direction of the gantry 24, and a traveling body 27 is disposed on the traveling rail 26.

The traveling body 27 is connected to a predetermined position of a timing belt 29 wound around a belt pulley 28 provided at both ends of the gantry 24, and the timing belt 29 is driven by a servomotor 30 provided below the gantry 24. By rotating, the traveling body 27 travels a desired distance.

As shown in FIG. 8, a chuck jaw 32 which is opened and closed by a cylinder 31 to chuck the end of the tube is provided at the front of the traveling body 27. A tube pushing cylinder 33 for pushing the tube out of the chuck claw 32 and detaching it from the chuck 32 is disposed.

A tube cutting device 23 is provided at the tip of the gantry 24. The tube cutting device 23 is a tube to which a rotating disk-shaped saw blade is moved up and down and fed. A metal saw 34 for cutting the body is employed, and the cut tube is taken out by a roller conveyor 35 disposed in front of the tube cutting device 23.

A printing device 4 is provided in front of the tube cutting device 23. The printing device 4 has a cylinder mounted on a support column 36 which is provided on the side of the gantry 24 as shown in FIG. 37
The elevating body 38 has an elevating body 38, and an ink jet nozzle 40 is attached to the elevating body 38 via a support arm 39. Further, when printing is performed by the jet nozzle 40, the tube is attached to the support arm 39 by the roller 2 on the gantry 24.
5, a roller 41 to be held between the rollers.

These devices are controlled by a control device 5. The control device 5 includes a main body control device 42 for controlling the entire device and a pipe cutting control panel 4 for controlling the tube cutting device 23.
3 and a printing control panel 44 for controlling the printing device 4.

When operating the pipe sizing and cutting apparatus, predetermined types of pipes are stored in each rack shelf 6 of the pipe storage rack 1. For example, the first stage accommodates 25A, the second stage accommodates 20A, and the third stage accommodates 15A. The stored data is set and input to the main control panel 42. Next, the main control panel 42 is operated to activate the tube sizing device 22, and the traveling body 27 is moved backward to the original position.

When the type and size of the pipe to be cut are input to the main control panel 42 and a start operation is performed, for example, if the specified pipe type is 20A, the lifting / lowering pipe transfer device 2
The lifting / lowering motor 18 is driven to raise the lifting / lowering beam 15 as shown in FIG. 6, and the guide body 19 for guiding the discharge of the pipe and the arm body 20 for receiving the pipe are connected to the second rack shelf 6.
Face.

Next, the cylinder 9 disposed on the second rack shelf 6 operates to rotate the rotating body 10 by 90 degrees. With the rotation of the rotating body 10, one tubular body received by the tubular body locking portion 11 of the rotating body 10 is cut out forward.

At this time, the next stand-by tube following the cut tube comes into contact with the circumferential portion of the rotating body 10 and is prevented from rolling forward. When the cut-out tube rolls on the guide 19, the rotating body 10 further rotates and returns to its original position, and the tube blocked by the circumferential portion is again received by the tube locking portion 11. To do. During this time, the tube further rolls on the arm body 20 and fits into the concave portion 21 at the distal end.

In this way, one tube is connected to the arm 20
Then, the lifting motor 18 is driven again to lower the arm 20, and the tube is transferred onto the roller 25 of the tube sizing device 22.

When the tube is transferred onto the roller 25, the traveling body 27 of the tube sizing device 22 moves forward to move the end of the tube to the position shown in FIG.
As shown in (2), chucking is performed by the chuck claw 32, and further forward, the distal end of the tube is protruded and retracted in front of the tube cutting device 23, and is brought into contact with a stopper (not shown) serving as a length measurement reference. It stops, and detects the distance that the traveling body 27 has moved from the origin, and measures the total length of the transferred tube. At this time, if the measured length of the tube is less than the length required for cutting, the traveling of the traveling body 27 is stopped.

If the measured length of the tube is appropriate, the cylinder 37 of the printing device 4 is operated to lower the ink jet nozzle 40 to bring the ink jet nozzle 40 closer to the surface of the tube. Then, the designated data, for example, the pipe type and dimensions are printed on the pipe surface.

When the printing of the data is completed, the stopper moves backward and the traveling body 27 starts moving forward again. When the leading end of the tube is sent out by a predetermined dimension to be cut from the cut surface of the metal saw 34 of the tube cutting device 23 due to the advance of the traveling member 27, the advance of the traveling member 27 is stopped and the tube cutting device 23 is driven. Then, the rotating metal saw 34 is lowered while holding the tube, and cut. The cut tube is discharged by the roller conveyor 35 at the front.

When the tube chucked by the traveling body 27 is to be further cut, it is further fed into the metal saw 34 by a predetermined amount and cut. When ending the cutting, the traveling body 27
Moves forward to a position approaching the metal saw 34, moves the chucked pipe to the roller conveyor 35 side as much as possible, and stops. Then, the chuck jaws 32 are released, and the piston rod of the tube pushing cylinder 33 at the back of the chuck jaws 32 is extended to separate the tube from the chuck jaws 32, and is discharged onto the roller conveyor 35 through the metal saw 34. It is.

As described above, by operating the main control panel 42, it is possible to automatically perform operations of taking out various tubes stored in the rack shelf 6, cutting them to a fixed size, and printing predetermined data on the tubes. it can.

[0032]

As described above, in the tube sizing and cutting apparatus according to the first aspect of the present invention, a tube storage rack for storing tubes by type, and a tube storage rack. It is equipped with a tube take-out device for taking out the tube, a fixed-size cutting device that cuts the tube, and a printing device that prints out and prints on the tube, and a control device that controls each means. A predetermined pipe can be designated from the pipe and automatically cut to a predetermined size.

[0033] In the tube sizing and cutting apparatus according to the second aspect of the present invention, the pipe take-out device is provided with a part of the circumference on the discharge side of each rack shelf of the pipe storage rack. A tube cutting device that cuts out a tube made of a cut-out rotating body one by one, and a lifting / lowering tube transfer device that lifts and lowers a tube cut from a rack shelf, takes it into an arm, and transfers it to a fixed-size cutting device. Thus, the pipe take-out device can be simplified, and the cost of the device can be reduced.
