The object of the present invention is to provide a novel and useful flare processing apparatus which slightly expands the open end of a glass tube in a trumpet shape.

Various glass tube flaring processing apparatuses and methods have been known. However, the present invention provides a flaring processing apparatus that has a completely different configuration from the conventional apparatus, so that homogeneous flaring processing can be easily and quickly performed automatically. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The flare mill of the present invention consists of five main parts: an expanded processing part (B), a tie support part (D), a chuck part (C), a glass tube supply / discharge part (A), and a heating device (E). First, when the feeder pipe is supplied to the chuck part C by the glass tube supplying and discharging part A, the chuck part C grips the glass tube and then rotates the feeder pipe to thrust in the axial direction of the glass tube. In this state, while the unsupported end is supported by the tie support part (D), while the open end part is heated, the expanded part B is operated to flare the workpiece joint end.

The detailed structure, action, and effect of the five main parts configured as described above are as follows.

(A) Glass tube supply / discharge unit:

In FIGS. 1 and 2, (1) is the supply, (2) is the delivery, (3) the lifting shaft, (4) the lifting shaft plate, and ( 5) is open and closed, 6 is reversible motor, 7 is gear head, and 8 is transverse. Several unshared common pipes (P) are directed toward the lifting shaft (3) along the upper surface of the slightly inclined supply section (1) (1), and then when the lifting shaft (3) reaches the position of the unshared common pipe (P), Only unopened common pipe (P) is mounted on the glass tube mounting plate (4), and the lifting shaft (3) pushes open and closes the opening / closing opening (5), which is lever-type, so that the unopened common pipe (P) is inserted into the glass tube of the chuck part (C). The impression is introduced to the ball (15). The glass tube P 'which has been flared is not opened when the elevating shaft 3 is lowered, so that the opening and closing opening 5 is not opened downward, so that the glass tube P' is discharged along the upper surface of the opening and closing opening 5 through the opening 5. 2) It is moved upwards and sent out of the device along the inclined surface of the delivery section (2) (2).

The lifting shaft 3 is configured by, for example, a rack shaft type, and is lifted by a pinion gear of the reversible motor 6 and the gear head 7. The supply section 1 (1) and the delivery section (2) (2) are constituted by a pair of rod members arranged in parallel at regular intervals, for example, slightly inclined. Glass tube mounting plate (4) is to be installed on the transverse (8) two or more, so that the side of the unshared common pipe (P) is lowered to match the upper surface of the supply (1) (1) and the other side is the supply (1) It is formed higher than (1) so that when the unshared common pipe (P) rolls on the mounting plate (4), it is no longer advanced to prevent it from falling out of the mounting plate (4). In addition, although not shown, a stopper is provided on the front surface of the supply section 1, 1 so that the unheated common pipe P placed on the spherical plate 4 can no longer move forward and fall off. Normally, the opening and closing opening 5 is in line with the inclined surface of the delivery section 2, and when the lifting shaft 3 rises from the bottom, it is filtered and opened, and after the lifting shaft 3 passes through the opening 5, It is to return to the original position.

(B) Extension processing department:

There is a separate application for registration of utility model for this part, but the outline of its composition and effect are as follows. In FIG. 3, 21 is a reversible motor, 22 is a gear head, 23 is a rotating shaft, 24 is a rotational shaft, 25 is a thermal fragment, 26 is a flap lever, (P ) Is a device such as a glass tube, 27 is a retreat, 28 is a blanket, 29 is a moving table, and s is a solenoid for advancing and retreating 27.

Referring to the action and effect of the present invention configured as described above are as follows.

First, when the opening end of the glass tube P, which is horizontally supported and actively rotated by the chuck part and the rail support part described later, is heated by the burner of the heating apparatus E, the shape may change when pressure is applied to this part. Can be reached (e.g., semi-softened), and then actuated the power unit (s) such as the solenoid to push the reinforcement (27) so that the gear head (22) connected to the movement (29) through the bracket (28). The flare lever 26 is pushed into the open end portion of the glass tube P through the pivoting shaft 24 and the connecting piece 25 which are connected to this in turn and are thus advanced.

Next, the reversible motor 21 is operated to rotate the pivot shaft 23 so that the flare lever 26 gradually presses the periphery of the open end of the glass tube P from the inside out to the outside in a constant press position. The flap lever 26 is stopped and the glass tube P continues to rotate and the glass tube P opening end is slightly expanded in a predetermined trumpet shape by the above-described constant pressure received by the flare lever 26.

When the operation process is completed, the above-described device 27 such as the solenoid is operated to retreat the advance leg 27 so that the flare lever 26 escapes from the glass tube end and separates the flared glass tube.

The present invention can be applied to a constant pressure at a constant position with respect to the glass tube opening end as described above, it is possible to perform a homogeneous flaring process, and the processing operation can also be performed very simply and quickly.

In addition, in the implementation of the present invention, the entrance position of the flare lever can be adjusted according to the position of the glass tube opening end part, and in this case, this can be done by adjusting the advance distance between the advancing and retreating portions of the rack shaft, and according to the diameter of the glass tube. Alternatively, the angle of rotation of the flap lever can be adjusted according to the degree of flaring (expansion), which allows precise and accurate flaring.

(C) Chuck part:

There is a separate application for registration of utility model for this part as well.

The glass tube P enters from the opening 14 of the chuck part C to reach the insertion hole 15. At this time, three sets of roller parts r-1, r-2, and r-3 are The round head of each roller support shaft 16 can move under the force of the spring 18 along the bottom face of the tapered cam 17 concave on the cam plate e. . At the top of each roller portion r-1, r-2, and r-3, rubber rollers 9, 9 ', 9' 'are respectively installed in the bearing casing 19 so as to rotate. have. Therefore, each roller part is composed of a roller support shaft 16, a spring 18, a bearing casing 19, a roller 9, or a 9 'or a 9', which are rotatably installed. The round head of the shaft is pressed against the inclined surface of the taper cam hole 17 and its shaft is held by the force of the spring 18 by the cam plate e which is rotated a predetermined angle by the action of the air cylinder (13 in Fig. 1). The advancing position of the rubber rollers 9, 9 ', 9' 'provided at the tip end can be adjusted. That is, when the head of the roller support shaft 16 is at the shallowest portion of the tapered cam opening 17, each spring 18 is compressed so that in this case each roller 9, 9 ', 9 " P) is firmly gripped by narrowing in three directions. On the contrary, when the head of the shaft 16 is at the deepest portion of the taper cam hole 17, each spring 18 is returned to its original shape, so that the glass tube P is rotated by each roller 9, 9 ', 9' '. It is completely released from the pressure of the holding force, that is, it is possible to freely enter and exit from the insertion hole (15).

In addition, each roller portion (r-1) (r-2) (r-3) when holding the blood share pipe (P) has only one motor of each roller (9) (9 ') (9' '). If the two rollers are driven through the glass tube (P), the relative positions of the rollers and the glass tube are always moved in form, but there is no change in the holding state.

In this case, the principle of operation of the thrust by the chuck is briefly described as follows.

The glass tube (P) is apparently completely horizontal in the direction of the road, its cross section is perfectly circular, and its surface seems to be uneven, but in fact, it is neither completely horizontal nor perfectly circular, and there is no unevenness on the surface. Also, in the case of each rubber roller, numerous irregular irregularities are formed on the surface. Therefore, in this state, when the roller is in contact with the glass tube and rotates, any one of the rubber rollers is slightly out of the orthogonal state with respect to the axial direction of the glass tube. At this time, a thrust acts on the glass tube (P) to move the glass tube (P) toward the tail support part. I can do it. Therefore, if this principle is to be used, it is possible to adjust the processed end of the shared pipe to be located at the correct processing position as in the case of the present invention.

Of course, the chuck for the chuck device of the present invention is composed of a rubber material having a sufficient friction force required for holding and rotating the glass tube (P).

(D) Tail support:

The rack shaft 32 in which the conical head 30 and the bearing support plate 31 are mounted on the front end is installed on the gear head 33, and the gear head 33 connects the reversible motor 34 to the glass tube. The end, that is, the support of the tail is formed. When the glass tube P is gripped by the three-way roller part of the chuck part, the tie support part is driven and the conical head 30 is inserted into the untailed tail of the glass tube P by the rotation of the reversible motor 34. And the thrust glass tube unprocessed end by the action of the chuck (C) is to be supported by the conical head (30) by touching the front of the support plate 31 accurately.

Summarizing the above, the overall configuration, action, and effect of the present invention are summarized as follows.

When the lifting shaft (3) descends and loads the Miga common pipe (P) into the mounting plate (4) of the government and ascends again and supplies it to the glass tube insertion hole (15) position of the chuck part (C), the air of the chuck part (C) The cylinder is operated to rotate the cam plate (e) to securely hold the glass tube (P) by the three rollers, and then rotate the rollers so that the thrust acts on the glass tube (P) so that the unprocessed end portion is supported by the tie (D). Close contact with the front surface of the support plate 31 to bring the end of the glass tube P to the correct processing position, and then insert the flare lever 26 of the expansion processing apparatus B into the glass end of the glass tube and heat the glass tube end. While heating with the apparatus E, the flare lever 26 rotates the glass tube end to be rotated at a constant pressure from the inside to the outside so that the glass tube end can be opened in the shape of a trumpet to complete the flaring process. The flared glass tube (P ') releases the holding state by the three rollers of the chuck (C), and lowers the lifting shaft (3) of the glass tube supply and discharge unit (A), the flared glass tube (P') is opened and closed. It is caught by (5), and it is sent out of the apparatus along the delivery interval 2 in line with the inclined surface.

As described above, according to the present invention, there is a glass tube supplying and discharging device (A) capable of automatically supplying a non-covalently shared tube and discharging the processed glass tube to the outside of the apparatus, so that the work can be quickly and continually improved to improve production efficiency. In addition, the glass tube can always grip and rotate the flare of a predetermined shape accurately, as well as the chuck (C) for actuating thrust and the tie support (D) for effectively supporting the glass tube non-processed end (tail). It is possible to accurately form the desired flare at all times, and the flare processing of the glass tube end by the automatic and constant pressure by the flare lever can provide a characteristic advantage that can achieve uniform quality.
