Hereinafter, a use example of the high speed automatic injector according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 6, the yarn bobbin shaft (69) on which the yarn bobbin (53), which is formed of several strands (referring to yarn) 54, is wound in a cylindrical shape, is mounted on the drive motor for the yarn bobbin (not shown). As the drive rotates, the yarn 54 is released from the yarn bobbin 53.

Since the yarn 54 released from the yarn bobbin 53 described above is given a predetermined tension by the tension adjusting unit E, the yarn 54 is supplied from the yarn bobbin 53 to the injection bobbin 56 and wound in the process of being wound. (54) Tangling (prevention of twisting) is prevented.

As power is applied to the above-described step motor 50 and driven, the drive gear 66 (shown as a bevel gear) mounted coaxially to the step motor 50 is rotated and engaged with the drive gear 66. Due to the driving of the pair of driven gears 67 and 68, the rotation shaft 58 is rotated in conjunction with the step motor 50.

The intermediate shaft 60 connected to the rotating shaft 58 via the belt 59 (referring to the timing belt) is rotated in association with the rotating shaft 58. The drive chains 63 and 64 installed in the drive gear 61 (drive sprocket is used) mounted on both ends of the intermediate shaft 60 and the driven gear 62 (drive sprocket is used) rotatably mounted thereon are provided.

Therefore, the guide bar 57 having both ends integrally fixed to the drive chains 63 and 64 by the above-mentioned fixing piece 71 moves up and down within the height of the injection bobbin 56 as the drive chains 63 and 64 are driven. As the reciprocating movement in the direction is carried out, the yarn 54 (named yarn) supplied from the yarn bobbin 53 is uniformly distributed by the guide rod 57 to the injection bobbin 56 rotatably arranged in a double row. Supplied.

On the other hand, the upper and lower ends of the seal 54 wound around the above-described injection bobbin 56 forms a conical shape and the center portion is wound while maintaining a cylindrical shape.

That is, since the rotational force from the above-described step motor 50 is transmitted to the drive gear 66 mounted on the shaft thereof and the pair of driven gears 67 and 68 engaged therewith, the rotation shaft 58 is rotated. At this time, the rotating shaft 58 changes the rotational direction in the forward and reverse directions at regular intervals according to the driving of the pair of electronic clutches 51 and 52, and thus the lifting and lowering direction of the guide rod 57 is changed.

At this time, due to the simplification of the structure according to the driving method of the pair of electromagnetic clutches (51, 52) installed in the left and right symmetrical type as the driving means for elevating the above-mentioned guide rod 57, the cost of the parts is reduced, and the damage and It can reduce the cost of post maintenance by replacing only the worn parts.

As described above, the rotational force according to the rotation shaft 58 is transmitted to the guide rod 57 through the belt 59, the intermediate shaft 60, and the pair of drive chains 63 and 64, so that they can rotate in a double row form. The guide rods 57 are reciprocated in the up and down direction within a predetermined stroke range between the injection bobbins 56 so as to be installed.

At this time, since the driving means for repeatedly reciprocating the guide rods 57 for distributing and supplying the seal 54 to the injection bobbin 56 is exposed to the open state, the worker frequently visually checks the normal operation of these during operation. It can be checked and confirmed, so it is easy to follow-up management, and when a problem occurs in the operation line, it can immediately take predetermined emergency measures.

Therefore, the thread 54 released from the yarn bobbin 53 described above is continuously passed through the tension adjusting unit E and the guide bar 57 in order to be arranged in a double row and rotated in the injection bobbin 56. Since it is supplied to, when the seal 54 is wound on the injection bobbin 56, the upper and lower ends form a cone shape and the center portion is wound in a cylindrical shape.

At this time, since the lifting speed of the guide rod 57 is uniformly maintained by the balance weight 65 integrally fixed to the aforementioned drive chains 63 and 64, the supply speed of the seal 54 to the injection bobbin 56 is increased. By keeping constant and preventing the thread 54 from being entangled, the yarn 54 is wound around the spray bobbin 56 to maintain a predetermined shape and shape, thereby improving product quality and reliability.

As described above, the high speed automatic injector according to the present invention has the following advantages.

It is a drive means for elevating the guide rod which is installed between a plurality of injection bobbins rotatably installed in a double row type, and guides the seal to be distributedly supplied to the injection bobbin. You can reduce cost and maintenance costs by reducing and replacing only those parts that are broken.

In addition, since the yarn is wound on the injection bobbin while maintaining the correct shape and shape (the upper and lower ends are wound in a conical shape and the middle and middle parts are wound in a cylindrical shape), the quality and reliability of the product can be improved.

In addition, since the guide rod driving means for dispensing and supplying the seal to the injection bobbin is opened, it is possible to check and confirm their normal operation at any time during the operation, so it is easy to follow-up management.
