Abstract

PURPOSE:To cut and insert a tubular part by providing a stock part to store a tubular part, a feeding part to feed said tubular part with succession of a certain size, a head to be inserted with the extreme end of the tubular part, a cutting part to rotate a cutting blade around the head, and a moving part to move the cut tubular part. CONSTITUTION:A sliding chuck 10 of a feeding part 7 holds a tubular part, is slided in the X direction to feed the tubular part, and the extreme end of the part is abutted to a stopper 14 of a head 11. At this time, a fixing chuck 8 holds the tubular part, and after a cutting blade 16 is slidingly moved by motion of a cylinder 18, the tubular part is cut off all over the circumference by rotation of a gear 20 due to rotation of a motor. Sequentially, the head 11 is separated from a cutting part 15 by sliding movement of a slider. At this time, the cut tubular part is held around a pin 12 of the head 11. Nextly, an actuator 23 is rotated, and after the head 11 is faced downward, the head 11 is descended again by motion of the slider 22, and then the part is inserted by sliding movement of a slider 14 in the V direction.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cutting and inserting device for tubular parts that continuously supplies tubular parts and performs cutting and insertion of a fixed size.

PRIOR TECHNOLOGY The conventional cutting and inserting device for tubular parts (see Fig. 7) is
As shown in the figure, there is a parts feeder 1 that stores pre-cut tubular parts, aligns them, and takes them out, a shoe 1-2 that stores the tubular parts that have been arranged and taken out in a straight line, and a shoe 1-2. The apparatus was comprised of a head 3 for taking out and holding the two north tubular parts, and a moving part 4 for moving the head 3 vertically and laterally to the insertion position. The tubular parts aligned and taken out from the parafeeder 1 to the short 2 are taken out with the head 3 at the tip of the shoe I・2,
In the transfer section 4, the tubular component was moved to the insertion position and inserted into a predetermined position.

Problems to be Solved by the Invention However, in the configuration shown in L, the tubular parts must be cut in advance, resulting in increased loss, and flexible tubular parts are difficult to align and take out using a parts feeder. SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a cutting and inserting device for tubular parts that can continuously supply tubular parts and cut and insert them at the same time.

Means for Solving the Problems In order to solve the above-mentioned problems, the tubular component cutting/inserting device of the present invention has a stock section for storing tubular components, a feeding section for feeding the tubular components in fixed size increments, and a tubular component cutting/insertion device according to the present invention. It includes a head into which the tip is inserted, a cutting section in which a cutting blade rotates around the head to cut the tubular component to a fixed size, and a moving section that is inserted into the head and moves the cut tubular component to an insertion position. ing.

The head is preferably configured to include a pin that serves as a core metal when cutting the tubular component and holds the cut tubular component, and a stripper that serves to push the tubular component back to the insertion position.

Function: With the above-described configuration, the present invention can continuously supply tubular parts, use the head as a core bar to cut a fixed size, and then simultaneously insert the tubular parts using the same head.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6. Reference numeral 5 denotes a stock section, which winds up and stores tubular parts. 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 places a constant tension on the tubular component. 7 is a feeding section, a fixed chuck 8,
In the cylinder 9, the feeding direction of the tubular part (arrow X direction)
It consists of a sliding chuck 1o that slides on the chuck 1o. Reference numeral 11 is a head, which has a tapered tip and has a groove formed at the cutting position, and a pin 12 that serves as a core bar during cutting and also holds the inner circumference of the tubular part in a regular manner after cutting, and a pin 12 that is fed by a feeding section 7. pin 12
The stripper 14 serves as a stopper for the tip of the tubular component inserted into the stripper 14, and also serves to push the tubular component by sliding in the direction of arrow V in the cylinder 13 during insertion. Reference numeral 15 denotes a cutting section, which includes a cutting blade 16 for cutting the tubular part, and a cutting blade 16 that slides oppositely to cut the tubular part.
It consists of a guide 17, two cylinders 18, and a gear 2o to which these are attached and which is rotated by the rotation of a motor 19 to rotate the tubular part. Reference numeral 21 denotes a transfer section, which includes a slider 22 that slides the head in the direction of arrow Z, and an actuator 23 that rotates this slider 22 in the direction of arrow Y.

Next, the operation will be explained. Sliding chuck 1 of feeding section 7
o holds the tubular part and slides it in the direction of arrow X, the tubular part is sent and its tip reaches the stripper 14 with the head
(See Figure 3). At this time, the fixed chuck 8 holds the tubular part, and then the cutting blade 1e slides due to the movement of the cylinder 18, and then when the gear 2o rotates due to the rotation of the motor 19, the tubular part is cut all around. It turns out.

The cutting dimension will be the diameter (see Figure 6). Next, the head 11 leaves the cutting section 15 by sliding the slider 22. 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 is lowered again by the movement of the slider 22 and comes to the insertion position.

The stripper 14 will then slide in the V direction and the tubular part will be pushed into the insertion position. After insertion, head 1
1 returns to the position of the cutting part 7. At this time, pin 12 is
It will be thrust into the tip of the tubular part. By repeating these operations, the tubular parts are continuously cut and inserted.

Effects of the Invention As described above, the present invention continuously supplies tubular parts, uses a head as a core metal to cut them into a fixed size, and then inserts them using the same head, thereby continuously cutting and inserting tubular parts. becomes possible.
