Description

Device for eliminating yarn remaining on cylinder

The present invention relates to a cylinder residue treatment apparatus, and more particularly, to a cylinder residue treatment apparatus for automatically removing a yarn on a cylinder after supplying yarn to a weaving process or knitting process.

In general, the cylinder supplying the yarn to the weaving machine or knitting machine is not used until all the yarns wound up are dismantled and replaced with a new cylinder with some yarn wound around the cylinder according to the quality or working condition of the final product. I use it. Thus, the amount of yarn remaining in the cylinder is usually from 10g to more than 300g.

Furthermore, in the knitting machine, the yarn is replaced with a new mandrel cylinder with more yarn remaining in the cylinder than in the weaving machine, so that a lot of yarn remains in the cylinder after use in the knitting machine.

Therefore, to wind the new yarn into the cylinder after use, it is necessary to completely remove the remaining residue, which was not easy by hand. In particular, synthetic fiber yarns such as polyester or polyamide are tough and cannot be removed with ordinary scissors or cutter. Therefore, special equipment should be used.

Therefore, when the yarn remaining in the cylinder is made of synthetic fibers, they are cut by intensive melting of a predetermined portion through a high temperature heater. However, even in this case, if the amount of yarn remaining in the cylinder is more than 100g, it takes a lot of time, and the residual yarns are attached to the surface of a small amount of cylinder without being completely removed. In particular, the yarns and pigtails near the flange of the cylinder remain unremoved, so they are manually inspected by hand while inspecting them one by one.

In addition, if the cylinder continues to be used, the edges of the cylinder, i.e., the flange portion, are crushed or crushed, which is a common reflection. For example, if such a flange is provided in the subsequent twisting process without removing the deformed cylinder, the deformed cylinder is not properly mounted on the drum of the twisting machine so that it does not rotate correctly and is idle. As a result of this problem, the company's T / M becomes inferior and causes deterioration of the final product quality.

The present invention is intended to improve the productivity by solving the waste that additional labor and time is additionally required as a small amount of yarn is not completely removed at a time when removing the residue remaining on the cylinder surface after being used during weaving and knitting As a result, the residue can be completely removed in a single process, thus eliminating the need for an additional follow-up inspection process and developing a simple cylinder residue treatment apparatus that can check the flange state of the cylinder.

That is, in the present invention, even if the amount of residue is large by controlling the degree of generation of heat according to the amount of synthetic fiber remaining in the cylinder, it is possible to melt and cut a portion within a short time, and even after cutting the chopped yarn mass quickly down It can be easily sucked and removed from the lower part by the suction drop, so that the surface of the cylinder can be completely processed and the structure of the cylinder inlet is improved to check the flange status of the cylinder during the residue treatment. It is possible to reduce the defect rate in the present invention and to adjust the distance between the moving parts appropriately, to provide a cylinder residue treatment apparatus that can be applied to all cylinders regardless of the size of the cylinder.

Hereinafter, with reference to the accompanying drawings to more easily understand the characteristics of the residue treatment apparatus of the cylinder according to the present invention will be described in detail.

The residue treatment apparatus A of the cylinder according to the present invention includes a cylinder introduction part 10, a residue removal part 20, and a cylinder discharge part 30, as shown in FIGS. 1 and 2. A residue waste reservoir 40 containing residues processed at 20, a known air compressor (not shown), and a motor (not shown) as a driving source for all means are provided.

In the cylinder introduction portion 10, a supply rail 11 for introducing the cylinder 1 to be treated is disposed at the inlet, and is supplied at a predetermined interval d as long as the thickness of the flange 1a of the cylinder 1. A cylinder guide portion 12 is mounted away from the wall of the rail 11.

(See Figures 1 and 9). The cylinder guide 12 is a strip-shaped long rod that is installed at both sides or one side of the cylinder 1 at a height such that the cylinder 1 does not interfere with the passage of the cylinder 1. It is detachable so that the said gap d can be adjusted according to the size of the flange 1a. That is, the cylinder 1 to be supplied proceeds to the residue removing unit 20 in a state in which the flange 1a is inserted in the gap d formed between the cylinder guide part 12 and the wall of the supply rail 11. . Thereby, the state of the flange 1a of the cylinder 1 can be checked in the cylinder introduction part 10, and the defective article can be screened out.

In addition, the residue removing unit 20, as shown in detail in Figs. 5A-5D, is blown with high temperature hot air of approximately 250 ° C or more, and is supported and coupled by both fixing parts 9 installed through the slot 8a. A cutter 21 is fixed to move up and down through the ball 25b to an operating position and a non-operating position, and is provided with a connecting hole 25a on its upper surface, and a large amount of high heat is supplied through the cutter 21. At least two heaters 25 are installed in the connection hole 25a so that they can be ejected, and they are located at the top and are operated up and down by the high pressure air discharged from the air compressor (not shown). The lifting and lowering motion is appropriately repeated in accordance with the movement of (5) (see FIGS. 2 to 3A and 3B).

The cutter 21 is formed to have a length substantially equal to the length between the two flanges (1a) of the cylinder (1) and is formed so as to blow out the air while being heated as a whole by high temperature, in particular the air is concentrated and blown out The width decreases downwards, the end of which is sharply shaped like a sharp blade that is good for cutting residue, and the interior of which air is subdivided into two or more spaces to induce intensive blowing of compressed air as necessary. May be In addition, in the vicinity of the end 21a of the cutter 21, a plurality of blow holes 26 are provided in two rows in a zigzag manner so that hot air is directly under the straight line. Further, both side surfaces of the cutter 21 are further provided with side blowout holes 27 formed to be inclined so that hot air is blown outwardly at an angle. Thus the end 21a of the cutter 21, which is operated in contact with the residue on the cylinder 1, must be inserted into both flanges 1a of the cylinder 1, thus substantially adjacent to the flange 1a of the cylinder 1. The hot air of the direct blower hole 26 cannot be applied to a small portion of about 2 mm, but is squared by the side blower hole 27 which is blown out by the residue treatment apparatus A according to the present invention. Hot air is also applied to both flanges 1a of the cylinder 1 without space. That is, the cutter 21 can completely melt even the residues adjacent to both flanges 1a of the cylinder 1 by a plurality of direct blow holes 26 and two side blow holes 27.

In addition, the residue removing unit 20, the upper cylinder support 23 for gripping and fixing the cylinder (1) to remove the residue on the supplied cylinder (1) and the cylinder (1) after the treatment drop the cylinder The rear cylinder support part 24 for holding when supplying it to the discharge part 30 is formed in two stages at one side or both sides of the body via the fixing part 9 ', and this upper and lower cylinder support part 23 ( 24 is detached or moved left and right by a plurality of slots 8b of approximately elliptical shape and fixing means 35 such as bolts so that the width of the portion through which the cylinder 1 passes can be adjusted according to the size of the cylinder 1. It is possible (see FIGS. 3A-3B).

As shown in FIGS. 2-4 and 6, the residue removing unit 20 is operated in the same manner as the heater 25 adjacent to one end of the flange 1a of the cylinder 1 to be processed to have a high temperature. An auxiliary heater 28 is provided to blow hot air and is connected to the air cylinder 5 to be adjacent to the lower end of the cutter 21 so that the high pressure cold air can be immediately blown off immediately after the cutter 21 is operated. The cold air nozzle 29 provided with the discharge hole is provided so that the residue wastes can be temporarily dropped down within a short time. In addition, an inlet 22 is installed below the cold air nozzle 29, and the inlet 22 is connected to an inhaler (not shown) located below the inside thereof, and an inlet 22 by an inhaler (not shown). The suction force in acts in conjunction with the cooling nozzle 29 so that the residue on the surface of the cylinder 1 falls well and serves to quickly send the residue to the external residue storage 40 connected thereto.

Furthermore, according to the residue treatment apparatus A of the cylinder according to the present application, in order to discharge the treated cylinder 1 to the outside, the cylinder discharge part 30 has an air cylinder for discharging the cylinder as shown in FIGS. 8A and 8B. (6) and the discharge rail 31 is provided in the discharge rail 31 to the upper and lower cylinders so as to pass smoothly on the discharge rail 31 in accordance with the size of the empty cylinder (1 ') to be discharged The adjusting bar 32 for adjusting the passage gap in the same manner as in the supporting parts 23 and 24 is connected to the discharge rail through the connection part 34 provided with the elliptical slot 33 and the fixing means 35 such as a bolt. It is detachably attached to both sides or one side of (31). Therefore, it is possible to prevent the damage of the ball cylinder (1 ') by accurate gripping according to the size of the ball cylinder (1'), the locking plate 36 is usually made of steel (鐵 材) is expensive, but the entire device In order to lower the unit cost of the veneer plate, spring steel plate, synthetic resin plate and hard board can also be formed. In addition, the discharge rail 31 may be provided with a flexible material in a dual structure so that its length can be adjusted in consideration of the overall size and the place of the arrangement.

Residual processing apparatus (A) of the cylinder according to the present invention having the structure as described above is the individual cylinder (1) when the plurality of cylinder (1) is located in the cylinder introduction portion 10 as shown in Figs. The flange 1a is inserted into the gap d between the cylinder guide 12 and the wall of the feed rail 11 and is introduced into the residue removing portion 20 as the feed rail 11 moves. Therefore, at this time, the flange 1a of the cylinder 1 is irregularly deformed and the cylinder 1 which cannot be inserted in the gap d is sorted by the cylinder introduction part 10 and taken out to the outside, so that the separate cylinder is sorted. This eliminates the need for a process and prevents the generation of defective products in subsequent processes.

The cylinder 1 introduced into the residue removing unit 20 through the cylinder guide 12 is enlarged in FIGS. 2 and 3A-B, in particular, as shown in FIG. 4. The hot air cutting machine 21 accompanied by the heater 25 is lowered by the upper air cylinder 5 which moves up and down, firmly held in the operating position by the upper cylinder support 23 with the passage interval adjusted appropriately. Then, a large amount of hot air is instantaneously blown out on the contact surface with the cylinder 1 through the blowing hole 26 and the side blowing hole 27 in the end portion 21a of the cutter 21. In other words, since a large amount of hot air of 250 ° C. or more exceeding the melting point of the synthetic fiber is ejected from the plurality of blow holes 26 and the side blow holes 27 of the cutter 21 to the contact surface of the cylinder 1, the contact The surface is melted and cut and at the same time hot hot air of the same temperature is ejected together from the auxiliary heater 28 as shown in detail in FIG. 7 and wound on the central protruding frame 1b of the flange 1a of the cylinder 1. Even the pigtail yarn 3 is melted and cut. Thereafter, while the cutter 21 and the auxiliary heater 28 are moved up and down, the cold wind nozzle 29 positioned near the lower portion descends and cuts on the surface of the cylinder 1 to generate high pressure cold air on the remaining waste. At the moment, the intensively ejected and falling down, and in parallel with this, the residue waste dropped by the strong suction force from the inlet 22 located at the lower side is sucked into the lower inlet 22 in an instant, and the residue waste storage ( 40).

The empty cylinders 1 ', which are processed in this order in order to remove the residue on the cylinder 1, are gripped by the lower cylinder support 24 as shown in FIGS. 1, 2, 3, and 3b, and discharge the cylinder. The ball cylinder 1 ', which is dropped by the action of the air cylinder 6, is dropped and is connected to the return spring 37, and an upper end thereof is stopped by a rotation shaft 38 so as to be able to swing in the discharge direction by a locking plate ( 36) is stopped once, and thus the discharge speed of the ball cylinder 1 'is lowered to some extent, and then discharged through the discharge rail 31 shown in FIG. At this time, the discharge rail 31 is also provided with a connecting portion 34 having an approximately oval slot 33 of a predetermined size in the control bar 32, the control bar 32 is left and right within the range of the slot 33. Since it can be adjusted to the size of the ball cylinder (1 '), the discharge interval on the discharge rail 31 is appropriately adjustable so that the ball cylinder (1') can be discharged smoothly without damage because the ball cylinder (1 ') proceeds firmly gripped.

As described above, the residue treatment apparatus A of the cylinder of the present invention automatically introduces, processes, and discharges one cylinder 1 in a series of processes, and in some cases, the cylinder introduction part 10 to further increase work efficiency. For storing the empty cylinder 1 'and the automatic introduction and discharge of a continuous cylinder 1 and a sensor operated in a known manner in each part such as the residue removal unit 20 and the cylinder discharge unit 30, etc. It can also be constructed so that the installation can be carried out continuously and completely unmanned.

According to the cylinder residue treatment apparatus of the present invention as described above, even the surface residue of the cylinder as well as the pigtails attached to the flange can be automatically and completely processed by a single process without additional manual work and at the same time Hot air can be discharged and the amount of ejection can be adjusted, so that even if the amount of residue is larger than usual, it can be melted and removed in a short period of time, thereby greatly improving production efficiency.

In addition, it is possible to check the flange deformed state of the cylinder at the same time while processing the residue of the cylinder. The width of the cylinder inlet, the residue removal unit and the cylinder outlet can be adjusted freely according to the size of the cylinder, so the discharge from the first cylinder introduction to the end Since it can be securely gripped and processed, it is possible to prevent damage to the cylinder and to smoothly and efficiently carry out the work in a series of fabric production processes, thereby reducing the defective rate of the product and lowering the manufacturing cost.
