Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting and inserting a tubular part which continuously supplies a tubular part and performs cutting and insertion of a fixed size.

2. Description of the Related Art As shown in FIG. 8, a conventional device for cutting and inserting a tubular component (see FIG. 7) includes a parts feeder 1 for storing and aligning and removing a previously cut tubular component.
A chute 2 for storing the tubular components taken out in a straight line, a head 3 for taking out and holding the tubular components on the chute 2, moving the head 3 up and down and laterally, and moving the head 3 to the insertion position The moving unit 4 is configured to move.
The tubular parts aligned and taken out from the parts feeder 1 to the chute 2 are taken out by the head 3 at the tip of the chute 2, moved to the insertion position by the transfer part 4, and inserted into the predetermined position. .

Problems to be Solved by the Invention However, in the above configuration, the tubular part must be cut in advance, which increases the cost, and in the case of a flexible tubular part, it is difficult to take out and align the parts using a parts feeder. Had.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a tubular component cutting and inserting apparatus capable of continuously supplying tubular components and simultaneously performing cutting and inserting.

Means for Solving the Problems In order to solve the above problems, a cutting and inserting apparatus for a tubular part according to the present invention comprises a stock part for storing the tubular part, a feeding part for feeding the tubular part by a fixed size, and the tubular part. The tip portion is inserted, a head holding the tip portion, a cutting portion for cutting the tip portion of the tubular component held by the head to a fixed size by a cutting blade rotating around the head, and a cut portion. A moving unit that moves the distal end of the tubular component to an insertion position while being held by the head, and inserts the tubular component in an arbitrary direction.

It is preferable that the head has a configuration including a pin serving as a metal core when the tubular part is cut and holding the cut tubular part, and a stripper serving to push into the insertion position after being moved to the insertion position.

The present invention, by the above-described configuration, the tubular component is continuously supplied, and after cutting a fixed size using the head as a core bar, the same head can be inserted simultaneously, and regardless of the feeding direction of the tubular component. An embodiment in which the tubular component can be reliably supplied and inserted in an arbitrary direction. An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 5 denotes a stock unit that winds and stores a tubular part. The roller 6 rises as the tubular part is fed, and when it reaches a fixed position, the stock part 5 rotates and descends. This results in a constant tension on the tubular part. Reference numeral 7 denotes a feed unit, and a fixed chuck 8
And a slide chuck 10 that slides in the cylinder 9 in the feed direction (arrow X direction) of the tubular component. Reference numeral 11 denotes a head, which has a tapered tip and a groove formed at a cutting position, which serves as a metal core at the time of cutting, and a pin 12 for normalizing and holding the inner periphery of the tubular component after cutting, and A stripper 14, which serves as a stopper at the tip of the tubular part inserted into 12, and which is slid in the direction of arrow V by the cylinder 13 at the time of insertion and serves to push in the tubular part. Reference numeral 15 denotes a cutting portion, which is a cutting blade 16 for cutting a tubular component.
And a guide 17 that slides the cutting blade 16 in opposition, two cylinders 18, and a gear 20 to which these are attached and that rotates these around a tubular part by rotation of a motor 19. . Reference numeral 21 denotes a transfer unit, which includes a slider 22 for sliding the head in the direction of the arrow Z, and an actuator 23 for rotating the slider 22 in the direction of the arrow Y.

Next, the operation will be described. Sliding chuck for feed unit 7
When the tubular part 10 holds the tubular part and slides in the direction of the arrow X, the tubular part is fed and its tip hits the stripper 14 of the head 11 (see FIG. 3). At this time, the fixed chuck 8 holds the tubular part, and then, after the cutting blade 16 is slid by the movement of the cylinder 18 and the gear 20 is rotated by the rotation of the motor 19, the tubular part is cut over the entire circumference. Will be. Cutting dimension is A
Dimensions (see FIG. 6). Next, the head 11 leaves the cutting portion 15 as the slider 22 slides. At this time, the cut tubular part is held around the pin 12 of the head. Next, after the actuator 23 rotates and the head 11 faces downward, the head 11 descends again by the movement of the slider 22, and comes to the insertion position. next,
The stripper 14 slides in the V direction and the tubular component is pushed into the insertion position. After insertion, the head 11 returns to the position of the cutting section 7. At this time, the pin 12 is pushed into the tip of the tubular component. By repeating these operations, the tubular component is continuously cut and inserted.

Effect of the Invention As described above, the present invention is to continuously supply a tubular component, cut the head to a fixed size as a core metal, and also perform insertion while holding the cut tubular component with the same head, The tubular component can be cut and inserted continuously and reliably, and the tubular component can be supplied and inserted in any direction regardless of the feeding direction of the tubular component.
