As shown in Fig. 1 and Fig. 2, the needle polishing apparatus 1 of the present invention, like a conventional general needle polishing apparatus, has a rotary gear 5, a drive device 7, and a polishing member on a base 3; (9) It consists of the structure in which the basic member requested | required of the back needle polishing apparatus 1 was provided.

The rotary wheel 5 is rotatably installed on the base 3, and is configured to adjust its circumferential speed by a drive device 7 such as an electric motor through a power transmission means 11 such as a chain or a belt. have. A plurality of grooves 5 'are formed on the entire outer circumferential surface of the rotational step 5 at regular intervals in a direction parallel to the axis 13 direction of the rotational step 5, so as to be adjacent to the upper outer circumference of the rotational step 5. The unpolished needles 17 loaded on the feed hopper 15 installed are fitted into these grooves 5 'one by one so as to be sequentially transported in the rotational direction of the rotary gear 5.

Around the lower side of the rotary wheel 5, polishing 9 'for initial polishing the needle 17 at a position corresponding to the tip of the needle 17 and a polishing roll 9 for finishing the polished needle 17 A polishing member 9 comprising "is supported on the base 3. These polishing members 9 are rotated by the electric motors 19 'and 19 " It is mounted on each support plate 21 ', 21 "so as to adjust and fix the relative position with respect to the needle 17, that is, relative to the needle 17 to be polished. Downstream, a collection box 23 is provided to receive the polished needle 17 falling from the rotary wheel 5.

Meanwhile, a plurality of needles 17 which are moved around the rotary wheel 5 are accurately positioned in the groove 5 'of the rotary wheel 5, and the needle 17 is not separated from the groove 5'. Guide plate is installed. That is, the first guide plate 25 made of a flat plate is fixedly attached between the rotational step 5 and the base 3, and the first guide plate is opposite to the rotational step 5 of the first guide plate 25. A second guide plate 27 facing the plate 25 is provided adjacent to the feed hopper 15. The first guide plate 25 is in contact with the end of the handle 17 'of the needle 17, the second guide plate 27 is in contact with the tip of the needle bar 17 ". Preferably, the second guide plate ( 27) is to adjust the distance to the first guide plate 25 according to the length of the needle 17 to be polished, and the needle guided by installing so that the opposite side is gradually narrower than the supply hopper 15 side (17) may be gradually pushed toward the first guide plate 25 so that the position is limited by the two guide plates 25 and 27 so as to be disposed in the correct position.

According to the configuration of the needle polishing device 1 as described above, the raw needles 17 loaded on the supply hopper 15 are mounted in the grooves 5 'of the rotary wheel 5 one by one, and As it rotates, it is transported toward the polishing member (arrow direction), and the tip 17 of the needle 17 is polished and collected in the collection box 23. In the process of polishing the needle 17 by the polishing member 9, the needle 17 inserted into the groove 5 'of the rotary tool 5 is polished while rotating by the means for rotating the needle.

In the present invention, as shown in Figures 1 to 4, the needle bar (17) by the rotary friction member 31 and the fixed friction member 41 as a means for rotating the needle 17 ( The structure which rotates 17 ") is adopted.

First, the rotary friction member 31 rotates together with the rotary step 5 in contact with the needle bar 17 "of the needle 17 into which the handle 17 'is fitted into the groove 5' of the rotary step 5. A friction member comprising a rubber having a coefficient of friction, wherein the friction member (35) is provided on the circumferential surface of the needle wheel (33) which rotates integrally with the rotary wheel (5) and is installed adjacent to the rotary wheel (5). 3, or the rotational step 5 in which the groove 5 'is formed is formed so as to extend without grooves in the axial direction toward the polishing member 9, and the friction rubber 35 is formed on the outer circumferential surface of the extension 37. ) Is covered with a structure (see Fig. 4).

The former rotating friction member 31, as shown in Figure 3, the handle of the needle 17 in a diameter similar to the diameter of the rotational step 5, more precisely in the groove 5 'of the rotational step 5 With the diameter of 17 'inserted, the diameter of the needle rod 17' can be naturally brought into contact with the needle rod 17 'at a position spaced inwardly from the tip of the needle rod 17' protruding in the axial direction from the rotary wheel 5 in the axial direction. The branch is a disk-shaped friction member having a predetermined width in which the friction rubber 35 is coated on the outer circumferential surface of the needle wheel 33. The needle wheel 33 is formed as a separate member and fastened like a bolt 39. The needle may be fixed to the rotary wheel or may be integrally formed when the rotary wheel 5. The needle bar length of the needle 17 to be polished is formed when the needle wheel 33 is formed as a separate member. By appropriately adjusting the distance between the rotary turn 5 and the needle turn 33 to ensure that the needle turn 33 is It is preferable in that it can be folded from a single location.

On the other hand, the latter rotational friction member 31 is larger than the width that can form the groove (5) necessary to fit the handle 17 'of the needle, without using a separate needle rotor as shown in FIG. Extends the width of the rotary gear 5 sufficiently wide, that is, extends the width of the rotary gear 5 to a position spaced inward by a predetermined distance from the tip of the needle bar 17 ", and the appropriate position of this extension 37 The friction rubber 35 is coated on the friction rubber 35 so that the appropriate position of the needle bar 17 "may be naturally in contact with the friction rubber 35. This latter rotational friction member 31 cannot easily cope with the difference in length of the needle bar 17 ", but has the advantage that the structure is simple.

Next, the fixed friction member 41 is installed so as to contact the rotating friction member 31 around the rotational wheel 5 over the left and right ranges of the polishing member 9 provided at the lower part of the rotational wheel 5. It consists of the rubber | gum 43 of a modulus, and the support 45 which supports this friction rubber 43. The contact range between the rotary friction member 31 and the fixed friction member 41 is in contact with the two friction members 31 and 41 over a distance sufficiently longer than the range where the tip of the needle 17 is polished by the polishing member 9. To be possible. The configuration of the support 45 for supporting the friction rubber 43 of the fixed friction member 41 is particularly limited as long as the friction rubber 43 is sufficiently in contact with the friction rubber 35 of the rotary friction member 31. 2, the first support 47 protruding from the base 3 in the position between the feed hopper 15 and the polishing member 9, and the position between the polishing member 9 and the collecting container 23. The structure which elastically hangs and mounts the friction rubber 43 between the 2nd support 49 which protruded from the base 3 is illustrated.

Here, the first and second support 47, 49, the rotational step (5) to match the length of the needle bar 17 "of the needle 17 to be polished when the needle wheel (33) is formed as a separate member (3) expect the position of the friction rubber 43 of the fixed friction member 41 in accordance with the position of the friction rubber 35 of the needle wheel (33) when adjusting the distance between the needle wheel (3) and the needle wheel (3) 1 and 2, the fastener 51 for adjusting and fixing the length of the friction rubber 43 with the first support 47 is moved along the guide bar 53. An example using a sliding and fixing structure is shown, wherein the second support 49 may be a structure in which the friction rubber 43 is bolted to the slit formed before and after, and moved back and forth and fixed (not shown).

On the lower circumferential surface of the rotary wheel 5 formed with the groove 5 'into which the handle 17' of the needle 17 is fitted, a third guide plate between the second guide plate 27 and the collection box 23 is provided. By installing 55, the handle 17 'fitted in the groove 5' can be prevented from being sag by gravity while the needle 17 in transit falls from the rotary gear 5 or the needle 17 is polished. (See FIGS. 1, 3 and 4).

In addition, the supply hopper 15, as shown in Fig. 2, the size of the neck (neck) in contact with the rotary wheel 5 is such that only one needle 17 can pass through, On the bottom surface of the feed hopper 15 adjacent to the neck, it is possible to mount the feed roll 16 with the rotational axis eccentric slightly. As a result, the needle 17 reaching the neck of the feed hopper 15 is inserted into the groove 5 'of the rotational step 5 through the neck while vibrating by the rotation of the eccentric feed roll 16. At the same time, the two needles 17 can be prevented from being entangled by interfering with each other between the needles 17 or the needles 17, so that the needles 17 can be smoothly supplied to the rotary needles 5. have.

In order to make the needle polishing operation by the needle polishing device according to the present invention more smoothly, unlike the example shown in FIG. 2, the collection point 23 ′ is dropped from the rotary wheel 5 of the polished needle 17. It may be installed in a lower position spaced apart from, and a needle feed conveyor may be installed between the dropping point of the needle and the collection box 23 '. 5 and 6 are schematic views showing an example of installing the needle feed conveyor, Figure 5 is a view showing the installation position of the needle feed conveyor, Figure 6 is a side cross-sectional view of the needle feed conveyor.

As shown, the needle conveying conveyor 61 is provided in the lower part of the point where the needle 17 falls from the rotary wheel 5. The needle conveying conveyor 61 has a width slightly wider (eg, 20 mm) than the handle of the needle 17 between the driving roll 63 and the driven roll 65 driven by the driving device 7. The belt 67 has a structure in which it hangs, and the rubber | gum protrusion 69 is attached to this conveyance belt 67 by a fixed space | interval (for example, 5-10 mm). In addition, a collection box 23 ′ is disposed at a lower side opposite to the rotary carriage 5 of the needle conveying conveyor 61. A sliding plate 71 is installed between the needle conveying conveyor 61 and the collection box 23 'to prevent the needle 17 falling from the conveying conveyor 61 to naturally slide and bounce off.

On the other hand, as shown in Figure 6, the needle conveying conveyor 61 is a frame (so that the handle 17 'is lower than the needle bar 17 "of the needle 17 is transferred on the transfer belt 67) ( 73 is inclined at a predetermined angle (for example, 15-20 °), and a pedestal 73 is attached to the handle 17 'to support the handle. In this way, the needle 17 conveyed on the conveying belt 67 is neatly conveyed without being released from the belt 67. In Fig. 6, reference numerals 75 and 77 denote a drive for rotating the drive roll 63. Show belt and drive pulley.

In accordance with the needle rotating means composed of the rotary friction member 31 and the fixed friction member 41 described above, the needle is conveyed by the rotary wheel 5, so that the two of the rotary friction member 31 and the fixed friction member 41 are fixed. When the friction rubbers 35 and 43 come into contact with each other, the rotational force is applied to the needle bar 17 "of the needle 17 in frictional contact between the two friction rubbers 35 and 43 by the rotational force of the rotary friction member 31. In this case, when the tip of the needle 17 is polished by the polishing member 9, the needle 17 can be rotated and polished, and the feed hopper 15 having the eccentric feed roll 16 can be polished. By the action, the raw needle is smoothly supplied to the rotary wheel 5, and the needle polished by the needle conveying conveyor 61 is smoothly collected.

According to the needle polishing apparatus according to the present invention described above, first, since the rotary wheel is used without driving the rotating belt using a separate power transmission mechanism to rotate the needle, the structure of the needle polishing apparatus can be simplified. Secondly, when rotating the needle, it rotates by turning a needle with a relatively small diameter. Therefore, it is possible to achieve high rotation of the needle with respect to the rotation speed of the same rotational wheel, rather than by rotating a large diameter knob, so that it is sufficient to rotate the rotational wheel at low speed. A needle turn can be obtained. Third, since the rubber of the needle rotating means supports the needle and the groove of the rotary wheel supports the handle, the position of the needle does not deviate during the polishing process. Fourth, because the support of the needle is stable, it is not necessary to form a groove of the rotary wheel tightly or install a separate needle support means, so it is not necessary to apply excessive force to the support of the needle, and therefore, the handle of the needle due to the excessive support structure of the needle The needle can be polished smoothly without scratching the needle bar. Fifth, the supply and collection of the needles can be performed smoothly by the feed hopper and the needle feed conveyor provided with an eccentric feed roll. The needle that can be polished per unit time according to various characteristics such as the sixth or more is 12000 / hour or more from 5000 / hour of the conventional automatic needle polishing device (Korean Utility Model Application Publication No. 93-5857 of FIG. 9). Not only can it be increased, but the polishing quality of the needle is also improved.
