Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically cuts a tube at a fixed length in the tube manufacturing process,
The present invention relates to a tube constant-length cutting device that sets the tip of the next tube on the winder.

[0002]

2. Description of the Related Art Conventionally, in a manufacturing process of a tube, for example, a silicone tube by extrusion molding, when a winding meter of a tube take-up machine reaches a set value, an operator cuts the tube with scissors, and the next The tip of the tube was set on the winder. Since it takes a lot of work in this way, especially in the case of a tube with many cuts,
Workers could not handle multiple machines at the same time.
In addition, since the tube is cut manually, the length tends to be incorrect.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is that even in the process of manufacturing a tube with a large number of cuts, each operation does not require a lot of labor, and an operator can simultaneously operate many machines. The object is to provide a constant-length tube cutting device that can be handled, can improve work efficiency, and can improve the accuracy and cut the tube quickly and easily.

This fixed-length tube cutting device is provided with a cutter on a table in front of a take-up machine so that the cutter can be opened and closed in a direction orthogonal to the take-up direction, and a uniaxial robot is provided above the take-up machine. It is mounted in the take-up direction, the cylinder is fixed downward at the tip of the uniaxial robot, and the air chuck is provided at the lower end of this cylinder so that it can be opened and closed in the direction orthogonal to the take-up direction. Is movably arranged between the take-out side of the take-up machine behind the cutter and the take-up machine in front of the cutter.

The tube length-cutting device of the present invention will be described in detail below with reference to FIGS. 1 is a front view of the above-mentioned standard length cutting device, FIG. 2 is a side view of the device shown in FIG. 1, FIG. 3 is a front explanatory view showing an operation of a main part in FIG. 1, and FIGS. 4A and 4B are side explanatory views showing the operation of the main part shown in FIG. In the standard length cutting device of the present invention, the uniaxial robot 2 is attached to the upper part of the take-up machine 1 in parallel with the take-up direction and horizontally. At the tip of the uniaxial robot 2, the cylinder 3 is oriented downward at a right angle.
The lower end of is fixed and the air chuck 4 is attached to the cylinder 3. Then, the table 5 is attached to the carry-out side of the take-up machine 1, and the two thin cylinders 6 are attached to the table 5 in a direction orthogonal to the take-up direction, that is, symmetrically so as to sandwich the tube T.

A cutter blade 7 is attached to a cutter holder 8 on one side of the thin cylinder 6, and an iron plate on which a rubber plate is attached as a blade receiver 9 is attached to the other side of the thin cylinder 6 to form a cutter as a whole. ing. It is advisable to fix the cutter blade 7 so that the cutter holder 8 holds the blade tip and is sandwiched from both sides. The rubber attached to the iron plate as the blade receiver 9 is preferably hard. The thin cylinder 6 has a capacity of 40 kg or more. The thin cylinder 6 on the blade receiving 9 side is the thin cylinder 6 on the cutter holder 8 side.
Same as or slightly larger ability. Further, it is preferable to provide a speed adjusting means so that the uniaxial robot 2 can convey the tube T following the take-up speed of the tube take-up machine 1. The claw 10 for chucking the tube T can be opened and closed by 180 ° so that it does not hit the cutter blade 7 and the blade receiver 9 when the uniaxial robot 2 moves forward and backward, and a gripping force of 5 kg or more is required. Good.

In FIG. 1, a frame is mounted on a take-up machine 1 by a square pipe, and a uniaxial robot 2 is fixed to the upper part of the frame so that it is horizontal to the take-up direction. A cylinder 3 is fixed to the tip of the uniaxial robot 2 vertically downward with respect to the uniaxial robot 2. The tube T is attached to the lower end of the cylinder 3.
The air chuck 4 for sandwiching is sandwiched and the pair of left and right claws 10 are attached to the air chuck 4 (see FIGS. 2 and 4).
Then, the table 5 is attached to the carry-out side of the take-up machine 1, and the two thin cylinders 6, 6 are attached to the table 5.
One cylinder 6 has a cutter blade 7 and a cutter holder 8
Attached to the other cylinder 6, and a rubber plate 11 attached as a blade receiver 9 is fixed to the other cylinder 6. The length of the tube T required for the counter 12 attached to the take-up machine 1 shown in FIG. 1 is set.
The pair of cylinders 6 and 6 move forward by 50 mm, and the uniaxial robot 2 holds the tube T and reaches the top of the winder 13 by 1000.
After advancing by mm, the cylinder 3 descends by 300 mm, and the tube T sandwiched on the winder 13 is released. Then, the winding of the tube T is started. After releasing the tube T, the uniaxial robot 2 returns to its original state and prepares to cut the tube T by sandwiching the tube T with the cutter blade 7 and the blade receiver 9. The transfer speed of the uniaxial robot 2 is determined by the pulse of the encoder attached to the take-up machine 1.

Any material that can be extruded may be used as the material of the tube used in the present invention, such as vinyl chloride resin, synthetic resin such as polyethylene and polypropylene, silicone rubber, butadiene rubber, butyl rubber, urethane rubber, fluororubber. Synthetic rubber such as is used.

[0009]

In the tube sizing device of this construction, when the tube is pre-wound to a sizing length in the tube manufacturing process, the claw 10 of the uniaxial robot 2 chucks the tube T and instantly cuts it with the cutter blade 7. A uniaxial robot 2 that cuts the tube T with the blade receiver 9 and grips the end of the tube T.
Moves forward to the position of the winder 13 and claws to the height of the winder 13.
After 10 has descended, the tube T is released. And tube T
Is rolled up. After releasing the tube T, the uniaxial robot 2 returns to the original position and prepares for the next tube cut.
The transport speed of the uniaxial robot 2 is adjusted according to the take-up speed of the take-up machine 1 (see the embodiment).

[0010]

According to the constant length tube cutting device of the present invention, when the length of the tube cutting device reaches the length preset in the counter, the tube is automatically cut and the end of the tube is set in the winder. Therefore, the man-hour can be greatly reduced. As a result, each worker can have five units.
