Description

A needle production machine using the automatic transfer belt and a method for manufacturing the needle production{KNITTING NEEDLE MANFACTURE MACHINE AND PRODUCTION METHOD USING AUTOMATIC TRANSFER BELT}

The present invention relates to a needle production machine and a method for producing a needle using an automatic transfer belt, and more particularly, to a needle production machine and a method for producing a needle using an automatic transfer belt for transporting the needle produced through the automatic transport belt.

Needles are classified into four types: bead needle, latch needle, double head needle, and compound needle. As for needle sewing, latch needle and double needle are mainly used, but bead needle and compound needle are also used for some knitting machines.

On the other hand, in addition to such needle-making, a device for producing a commonly used needle produces a needle by molding a metal material cut into a certain length. That is, a needle is produced through a process of injecting a material, transporting it simultaneously with molding, and recovering it.

Such a needle manufacturing apparatus is difficult to obtain a high-quality needle because it does not have an additional component for removing the residue generated during the molding process, and the user may experience burns and burns in the process of recovering the heated needle through a cutting or polishing process. There is a problem of getting the same skin damage.

For example, specific shapes, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with one embodiment. In addition, it should be understood that the location or placement of individual components within each disclosed embodiment can be changed without departing from the spirit and scope of the invention. Therefore, the following detailed description is not intended to be taken in a limiting sense, and the scope of the present invention, if appropriately described, is limited only by the appended claims, along with all ranges equivalent to those claimed. In the drawings, similar reference numerals refer to the same or similar functions throughout several aspects.

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

The needle-making machine using the automatic conveying belt according to the present invention and the method for producing the needle-making are automatically transported through the belt part in the needle-forming part, thereby applying physical force to the needle-making and transferring it to the recovery part. By reducing the to obtain a high-quality needle, it is possible to improve the loading efficiency of the finished product by easily aligning the stable transported needle.

1 is a front perspective view of a needle production machine using an automatic transfer belt according to an embodiment of the present invention. FIG. 2 is a rear perspective view of the needle making machine using the automatic transfer belt of FIG. 1.

Referring to Figures 1 and 2, the production machine 1 using an automatic transfer belt according to an embodiment of the present invention is a material injection unit 11, a needle molding unit 13, a belt unit 15, a recovery unit 17 and a driving unit 19, and may further include an air compressor (not shown).

The material injection part 11 may be injected with the impregnating material before molding as shown in FIG. 2. The impregnating material may be inserted into the rear of the material injection part 11 while being molded to a constant length. In detail, the impregnation material may be injected in the height direction from the rear of the material injection unit 11, and the injected impregnation material may have a plate shape having a constant thickness. The material injection part 11 may sequentially discharge the inserted impregnation material through the lower end, thereby transferring it to the impregnation forming part 13.

The needle-forming part 13 may mold the needle-making material discharged from the material injection part 11 into a predetermined shape. The needle-forming part 13 may cut or polish the needle-making material in a predetermined form. The needle forming part 13 may locally heat the needle material during cutting or polishing, and in this case, a heated burr may remain on the outer circumferential surface of the molded needle. The needle-forming part 13 may discharge the molded needle to the belt part 15 that is automatically driven from the bottom.

The belt portion 15 may separate burrs generated during molding of the needle-making material in the needle-forming mold 13 from the needle 9. The belt portion 15 can automatically transport the molded needle 9 in a predetermined direction. In detail, the impregnation 9 discharged to the belt portion 15 can be primarily removed from the burr weakly coupled to the belt portion 15 through impact. Thereafter, the separated needles 9 and burrs may be automatically transported from the surface of the belt portion 15 toward the recovery portion 17.

Meanwhile, the belt portion 15 may be coated with sandpaper on the surface of the molded needle 9. Depending on the frictional force of the sandpaper-coated belt portion 15, burrs separated from the surface of the needle 9 can be selectively retained during the transfer of the needle 9 to the recovery unit 17. This is a phenomenon in which the friction force caused by the sandpaper can be induced by acting larger than the inertia to move along the belt portion 15, and the sandpaper having high friction force is coated on the belt portion 15 Accordingly, the amount of burrs remaining may be improved.

In addition, the distance between the belt forming part 13 and the needle forming part 13 may be changed according to the size of the driving part 19 or the height at which the recovery part 17 is installed. Details related to this will be described with reference to FIGS. 3 and 4 below.

The recovery part 17 can store the needle needle 9 carried in the belt part 15. The recovery unit 17 may secondaryly remove burrs remaining in the needle 9. The recovery unit 17 can align the needle 9 by itself. The recovery unit 17 may be connected to a pallet for storing the needle 9 when necessary.

On the other hand, the recovery unit 17 is spaced apart by a predetermined distance from the belt unit 15, it is possible to selectively recover the needle transported from the belt unit 15. That is, the recovery unit 17 can selectively recover the needle 9 having an inertia force greater than the frictional force of the belt portion 15 coated with sandpaper. Detailed components and features of the recovery unit 17 will be described with reference to FIG. 5.

The driving unit 19 may transmit power to the belt unit 15. The driving unit 19 may rotate by receiving external power. The driving unit 19 must be provided in order to automatically drive the belt unit 15, and it is possible to change the driving conditions of the belt unit 15 by adjusting the angular velocity and size of the driving unit 19. Examples of changing the driving conditions of the belt unit 15 through the driving unit 19 will be described in detail with reference to FIGS. 4 and 5 below.

The air compressor may be additionally provided to remove burrs remaining on the belt portion 15 separated from the needle 9. For example, the air compressor may be disposed at the lower end of the belt unit 15 to transfer the needle to the recovery unit 17 to remove burrs remaining. As another example, the air compressor is located at the rear of the needle forming part 13 to cool the upper surface of the belt part 15 being driven, and a needle making machine using an automatic conveying belt for burrs remaining in the belt part 15 (1) can be dispersed outside.

FIG. 3 is an enlarged view of a driving part of the needle making machine using the automatic conveying belt shown in FIG. 1, and FIG. 4 is an enlarged view of a roller of the needle making machine using the automatic conveying belt shown in FIG. 1.

3 and 4, the driving unit 19 may include an electric motor 191 and a roller.

The rotational motion of the electric motor 191 may be induced based on electric power. The rotational motion generated in the electric motor 191 may be transmitted to the first roller 193 through a band connected to one end as shown in FIG. 3. The electric motor 191 may control the transport speed of the belt unit 15 by changing the angular speed of the rotational movement according to the speed at which the material is injected from the material injection unit 11. In addition, the motor 191 may control the transport speed of the belt unit 15 by changing the angular speed of the rotational movement based on the speed at which the needle is molded in the needle forming unit 13. In addition, the motor 191 can control the transport speed of the belt unit 15 by adjusting the rotation speed of the first roller 193 by changing the diameter of the band-connected portion.

The roller may include a first roller 193 and a second roller 195 as shown in FIG. 4. The first roller 193 may have one end 1931 connected to the electric motor 191. The other end 1933 of the first roller 193 may be connected to the belt portion 15. The first roller 193 may transmit the rotational force generated by the electric motor 191 to the belt unit 15. The first roller 193 may be additionally provided with a cover to prevent foreign substances such as burrs from being inserted therein.

In addition, the first roller 193 may have different diameters at one end 1931 and the other end 1933. The first roller 193 may transmit a different rotational force to the belt unit 15 according to the ratio of the diameter of one end 1931 and the diameter of the other end 1933 to control the transport speed of the belt unit 15.

In detail, when the diameter of one end 1931 connected to the electric motor 191 is smaller than the diameter of the other end 1933 connected to the belt part 15, the one end 1931 and the other end 1933 rotate at the same rotational speed. Even if the moving distance of the belt portion 15 connected to the other end 1933 is improved, a high transport speed may be exhibited.

Conversely, if the diameter of one end 1931 connected to the electric motor 191 is larger than the diameter of the other end 1933 connected to the belt part 15, even if the one end 1921 and the other end 1933 rotate at the same rotational speed. As the moving distance of the belt portion 15 connected to the other end 1933 is relatively reduced, a low transport speed may be exhibited.

As such, the speed of the belt portion 15 can be controlled through design deformation of one end 1931 and the other end 1933 of the first roller 193, and an operator can control the speed of the belt portion 15 A first roller having various specifications of one end 1931 and the other end 1933 can be mounted on the needle making machine 1.

The second roller 195 may be connected to the other end of the same size as the other end 1933 of the first roller 193. The belt portion 15 may be connected to the other end of the second roller 195. The second roller 195 may be disposed at a distance from the first roller 193 to assist driving the belt unit 15 and support the belt unit 15. The second roller 195 is preferably disposed sufficiently spaced from the needle forming part 13 so as not to interfere with the movement of the needle forming part 13, and a cover for preventing foreign matter such as burrs from being inserted therein May be additionally provided.

On the other hand, the first roller 193 and the second roller 195 can adjust the separation distance between the belt portion 15 and the needle-forming part 13 according to the diameter of the other end. In detail, the belt portion 15 may be provided with an additional device to adjust the height according to the body shape of the operator, but is connected to a roller having the other end having a large diameter to narrow the separation distance from the needle-forming part 13, It is connected to the roller having the other end having a small diameter to increase the separation distance between the needle-forming part 13 and the distance between the belt part 15 and the needle-forming part 13.

FIG. 5 is an enlarged view of a recovery part of a needle production machine using the automatic transfer belt shown in FIG. 1.

Referring to FIG. 5, the recovery unit 17 may include a first screw 171, a second screw 173, a first guide 175 and a second guide 177.

The first and second screws 1931 and 1933 may have a pitch wider than the thickness of the molded needle, which may be formed on the outer circumferential surface. The first and second screws 1931 and 1933 can be aligned by conveying the needle inserted in the pitch in one direction. In this case, the pallets are connected in the direction in which the first and second screws 1931 and 1933 transport the needles, and the aligned needles can be easily stored. By changing the rotation directions of the first and second screws 1931 and 1933, the direction in which the needle is transported can be changed, and the operator can change the rotation directions of the first and second screws 1931 and 1933 according to the working environment. It is possible to improve the convenience of collecting the needles.

The first screw 171 can be rotated repeatedly in a fixed position. The first screw 171 may be formed on the outer peripheral surface with a pitch for inserting the needle, and by repeatedly rotating at a fixed position, the needle inserted in the pitch may be moved in one direction.

The second screw 173 may rotate in the same speed and direction as the first screw 171. The second screw 173 may be fixed in a position spaced apart from the first screw 171 at an interval shorter than the length of the molded needle. The second screw 173 may be formed on the outer circumferential surface with a pitch for inserting a needle that has an area inserted into the pitch of the first screw 171. The needles moving in one direction can be moved at the same speed and direction.

On the other hand, the recovery unit 17 does not place an additional cover in the spaced apart between the first screw 171 and the second screw 173, so that the burr separated from the needle by the rotation of the screw downwards Can be discharged.

The first guide 175 may primarily supply the pitch of the first screw 171 and the second screw 173 by first aligning the needle transported from the belt unit 15. The first guide 175 is a valley-shaped guide in which the space becomes narrower toward the lower portion, and the needle separating from the belt portion 15 may be discharged through the lower portion. In the needle recovery recovered from the belt portion 15 to the first guide 175 carried, the burrs remaining at the same time as the collision may be removed. Burrs removed from the first guide 175 are discharged to the bottom, and the needle discharged by the first guide 175 can be inserted into the pitch of the first screw 171 and the second screw 173. .

That is, the first guide 175 is a structure for seating the needle transported from the belt unit 15 with the first and second screws 1931 and 1933, through which the needle movement moved in one direction is the first and second. It can be aligned parallel to the pitch of the screws (1931, 1933).

The second guide 177 may secondaryly align the needle needle moved in one direction through the first screw 171 and the second screw 173. The second guide 177 is a guide defined by both side walls of the recovery unit 17, and the needles discharged from the first guide 175 may be aligned side by side. To this end, the second guide 177 may have a narrow width between both side walls along one direction in which the needle movement moves. In detail, the second guide 177 has a wide separation distance at the position where the needle is discharged from the first first guide 175, and moves in one direction by maintaining only a slightly wider separation distance than the length of the needle in one direction in which the needle movement moves. The tips and tails of a plurality of needles can be aligned side by side. As such, a plurality of needles are aligned side by side through the second guide 177, so that the operator can easily identify defective products having different lengths or a plurality of burrs attached through the naked eye.
