Description

  The present invention relates to a cylindrical comb mainly used for a comb, a method for producing the same, and a side plate used for them.

Comb cylindrical combs have been provided for a long time, with serrated wires arranged in the axial direction and fixed on the cylindrical surface of an aluminum-based base in the circumferential direction. (For example, refer to Patent Documents 1 and 2.) On the other hand, it is also well known that the needle tip or the tooth tip is arranged with a predetermined inclination angle with respect to the circumferential direction of the cylindrical surface to improve the handling efficiency of the needle or the tooth with respect to the fibers (for example, Patent Document 1, 3). At present, it is the mainstream to obtain sufficient handling efficiency by zigzag arrangement of several sections in the circumferential direction as seen in Patent Document 1. In addition, in accordance with the zigzag arrangement of the sawtooth wires and the change of the tooth type to several divisions in the circumferential direction, the sawtooth wires are also divided and arranged in each circumferential division unit. (For example, refer to Patent Document 2). The present applicant has conventionally provided a cylindrical comb as shown in FIG. In this example, four types of sawtooth wires b to e are arranged in the circumferential direction A on the cylindrical surface of the base a from the teeth having a large pitch in the circumferential direction to those having a small pitch in the circumferential direction A. ~ E are arranged in the axial direction B. As an example, the inclination angle θ with respect to the circumferential direction A from one to the other in the circumferential direction is determined for each of the sawtooth wires b to e for each arrangement section. It is assumed that they are arranged in the axial direction B in the reverse direction. As shown in FIG. 7, flat side plates f and f are attached to both ends of the base a in the axial direction B by screws g as shown in FIG. 7, and the tips of the serrated wires b to e are left and covered from both sides. I try to protect it.

  By the way, when the serrated wires b to e are arranged straight in the circumferential direction A of the cylindrical surface of the base a, the teeth following the head are difficult to work on the fiber running in the circumferential direction A, and the handling efficiency is reduced. When arranged with a predetermined inclination angle θ with respect to the circumferential direction A, all the teeth of the serrated wires b to e work on the fibers running in the circumferential direction A, and the handling efficiency increases, but the pitch and inclination of the teeth In relation to the angle θ, if the inclination angle θ is too small, the handling degree is too high, and the fiber is scratched or causes fiber breakage. Conversely, if the inclination angle θ is too large, the handling degree is lowered. This is a problem especially in a comb that improves the quality of a sliver spun out of a card.

  However, in order to arrange the sawtooth wires b to e in the axial direction B with a predetermined inclination angle θ for each arrangement section, the direction cannot be uniquely determined, and the work requires skill and a long time. There may be individual differences. In addition, the fixing by bonding the serrated wires b to e is performed by arranging and arranging the serrated wires b to e on the adhesive application surface in which an adhesive is applied to the cylindrical surface of the base a and pressing the base a. While maintaining the state, specifically waiting for the adhesive to solidify with weights placed on the arranged sawtooth wires b to e, in the process, the sawtooth shape depends on the speed of the work, the roughness, etc. The wires b to e are inclined or displaced by an unconstrained state in the gap s corresponding to the inclination angle θ as shown in FIG. 6 generated between the side plate f and the bias balance or collapse. The arrangement and arrangement may be distorted or disturbed. These cause a decrease in yield, a decrease in quality, and an increase in product cost.

To cope with this, a groove is formed on the cylindrical surface and a sawtooth wire is fitted, so that both the base and the sawtooth wire are complicated, which increases the momentum cost.
The inventor of the present invention has a side plate f that protects the sawtooth wires b to e against external force from the side, and performs only a protective function to prevent a person or an object from being caught by being caught from the side. Focusing on the fact that it is located in the immediate vicinity of both sides of the serrated wires b to e, the above-mentioned problems have been solved.

  Accordingly, an object of the present invention is to provide a cylindrical comb capable of easily and stably arranging, arranging and fixing a sawtooth wire so as to have a predetermined inclination angle without individual differences or deviation or displacement at the time of adhesive solidification, a manufacturing method thereof, and the like It is in providing the side plate used for.

  In order to solve the above-mentioned problems, the comb comb of the present invention is a shaft that has a predetermined inclination angle with respect to its circumferential direction on the cylindrical surface of the base between the side plates attached to both axial end surfaces of the base. A comb-shaped cylindrical comb having sawtooth wires arranged and fixed in a direction, wherein the sawtooth wires arranged at one or both side plates with the predetermined inclination angle are copied so as to have a predetermined inclination angle. One of the features is that a gauge surface is provided in the direction to be pushed.

  In such a configuration, the side plate is attached to the axial end surface of the base, so that the inclination direction and position of the gauge surface with respect to the circumferential direction of the cylindrical surface of the base are unambiguous with respect to the axial end surface of the base. It is decided. Thereby, by arranging the serrated wires in the axial direction sequentially along the gauge surface, it can be arranged and arranged quickly and with a predetermined inclination angle easily and stably without individual differences. Since the serrated wire after placement remains along the gauge surface, the work speed and roughness are kept in the process of keeping the base pressed against the cylindrical surface by weight etc. until the adhesive solidifies. Because of this, the arrangement and arrangement are difficult to move or displace, and if the side plates on both ends have gauge surfaces, a state where the sawtooth wires arranged in the axial direction are sandwiched between the parallel gauge surfaces on both sides is obtained. Accordingly, it is possible to reliably prevent the arrangement and arrangement of the sawtooth wires from being distorted or displaced.

  Such a cylindrical comb includes a step of attaching a side plate to both axial end surfaces of a base having a cylindrical surface, a step of applying an adhesive to the cylindrical surface of the base, and a gauge surface formed with a sawtooth wire on the side plate. In the same manner as the above, the step of axially arranging on the adhesive application surface with a predetermined inclination angle with respect to the circumferential direction of the base, and solidifying the adhesive while pressing the arranged sawtooth wires against the cylindrical surface of the base A comb-shaped cylindrical comb manufacturing method characterized in that the saw-toothed wires can be arranged and arranged quickly with a predetermined inclination angle easily and stably without individual differences, and bonded. In the process of maintaining the pressed state of the base on the cylindrical surface by weight or the like until the agent is solidified, it is possible to make the arrangement and arrangement out of order and difficult to displace.

  The manufacturing method of the cylindrical comb of the present invention also includes a step of attaching side plates to both axial end surfaces of a base having a cylindrical surface, a step of applying an adhesive to the cylindrical surface of the base, and a method of forming each side plate. A step of axially arranging the sawtooth wire on the adhesive application surface by regulating the direction of the sawtooth wire between the parallel gauge surfaces which are oriented so as to follow the predetermined inclination angle with respect to the circumferential direction of the cylindrical surface. And a step of solidifying the adhesive while maintaining the pressed state of the arranged serrated wires against the cylindrical surface of the base, and fixing the serrated wires to the cylindrical surface of the base. Compared to the case of one feature, in particular, a state in which the sawtooth wires arranged in the axial direction with the side plates at both ends having gauge surfaces are regulated and sandwiched between the parallel gauge surfaces on both sides is obtained. Wai It can be arranged and the arrangement of crazy or, to reliably prevent or displaced.

  In addition to the cylindrical comb, the serrated wire is divided into a plurality of sections in the circumferential direction, and the angle of inclination of the serrated wire with respect to the circumferential direction is reversed regularly or irregularly depending on the sections. The gage surface of the side plate can be characterized in that the direction is reversed from one circumferential side to the other by the division corresponding to the reversal of the inclination angle of the sawtooth wire for each division.

In such a configuration, in addition to the above-described cylindrical comb, the sawtooth wire is further divided into a plurality of sections in the circumferential direction of the cylindrical surface of the base, and the sawtooth wire is inclined for each section. The type of angle and tooth can be selected, and the inclination angle is reversed regularly or irregularly sequentially from one side section to the other side section in the circumferential direction, and the preceding section and the following section where the inclination angle is reversed, Depending on the difference in inclination angle, the direction of tooth alignment can be combined with different handling effects on the fiber running in the circumferential direction, eliminating or reducing the bias of the handling action due to the inclination angle on one side, regular Inversion can be made finely and uniformly, and irregular inversion can be freely dealt with by a complex pattern in which the rule is not applied to the tooth type.
The side plate can be a synthetic resin molded product.

  In such a configuration, the gauge surface of the side plate is formed so as to protrude to the cylindrical surface side on the inner surface of the protruding portion that protrudes outward from the cylindrical surface from the attachment portion of the side plate to the base axial end surface. A synthetic resin molded product can be obtained easily and at a lower cost than metal.

  The invention of the above-mentioned cylindrical comb or the method of manufacturing a cylindrical comb according to the present invention is also characterized in that, as side plates used in them, both ends in the axial direction of a base having a cylindrical surface on which sawtooth wires are arranged in the axial direction and fixed with an adhesive.

  According to the cylindrical comb of the present invention and the manufacturing method thereof, the inclination direction and position of the gauge surface of the substrate relative to the circumferential direction of the cylindrical surface of the base are based on the axial end surface to which the side plate of the base is attached. By uniquely arranging the sawtooth wires in the axial direction along the gauge surface, the sawtooth wires can be arranged and arranged quickly with a predetermined inclination angle easily and stably without individual differences. In the process of maintaining the pressed state against the cylindrical surface of the base until the adhesive is solidified by guiding and holding by the gauge surface, it is difficult to arrange and displace or displace, and the side plates at both ends have gauge surfaces And by guiding and holding the serrated wire from both sides, it is possible to reliably prevent the arrangement and arrangement of the serrated wire from being misplaced or displaced, so it is highly productive and yields with high accuracy. Is also high, the product cost is reduced.

Hereinafter, a cylindrical comb according to the present invention, a manufacturing method thereof, and embodiments of a side plate used for the same will be described with reference to FIGS. 1 to 5 for the understanding of the present invention. However, the following description is a specific example of the present invention and does not limit the scope of the claims.
The cylindrical comb 1 according to the present embodiment shown in FIGS. 1, 2 and 5 is formed on the cylindrical surface 3 of the base 2 having an arc-shaped cross section made of aluminum as shown in FIG. A side plate 6 attached to both end faces 4 and 4 of the base 2 as viewed in the axial direction B by screws 5 shown in FIG. 5 and by bonding so as to have a predetermined inclination angle θ as shown in FIG. , 6 has a sawtooth wire 7 arranged and fixed in the axial direction B, and one or both of the side plates 6, 6 have a predetermined inclination angle θ as shown in FIG. A gauge surface 8 is provided in such a direction that the saw-toothed wires 7 arranged in such a manner can be copied so as to have a predetermined inclination angle θ. In the illustrated example, both side plates 6 and 6 are provided with gauge surfaces 8, and the pair of gauge surfaces 8 and 8 facing each other in the axial direction are parallel to each other as shown in FIGS. 1, 3, and 4. Become.

  As described above, the side plates 6 and 6 are attached to the end surfaces 4 and 4 in the axial direction B of the base 2, so that the side surfaces 6 and 6 are in the circumferential direction A of the cylindrical surface 3 of the base 2 as shown in FIGS. The inclination direction and position of the gauge surface 8 are uniquely determined based on the end surfaces 4 and 4 in the axial direction B of the base 2. As a result, the sawtooth wires 7 are sequentially arranged in the axial direction B along the gauge surface 8 so that they can be arranged and arranged quickly with a predetermined inclination angle θ easily and stably without individual differences. . Further, since the sawtooth wires 6 after being arranged and arranged remain along the gauge surface 8, as shown in FIG. 5, the cylindrical body of the base 2 by the weight 11 or the like on the work table 10 until the adhesive 9 is solidified. In the process of keeping the pressed state on the surface 3, it is difficult to arrange or displace or displace due to the speed or roughness of the work, and the side plates 6 and 6 at both ends are connected to the gauge surface 8 as shown in the illustrated example. 1, the state in which the sawtooth wires 6 arranged in the axial direction B as shown in FIG. 1 are sandwiched between the parallel gauge surfaces 8 on both sides is obtained. It is possible to reliably prevent the arrangement from being distorted or displaced.

  Such a cylindrical comb 1 includes a step of attaching the side plates 6 and 6 to both end surfaces 4 and 4 in the axial direction B of the base 2 having the cylindrical surface 3, and an adhesive 9 on the cylindrical surface 3 of the base 2. The step of applying and the axial direction on the adhesive application surface so that the sawtooth wire 7 has a predetermined inclination angle θ with respect to the circumferential direction A of the base 2 following the gauge surface 8 formed on the side plates 6, 6. The sawtooth wire 7 can be made without individual difference by a manufacturing method including the step of arranging the sawtooth wire 7 on the cylindrical surface 3 of the base 2 and the step of solidifying the adhesive 9 while pressing the arranged sawtooth wire 7 against the cylindrical surface 3.

Make it difficult to move or displace Can.

  As a result of the above, the inclination direction and position of the gauge surface 8 of the gauge surface 8 of the substrates 6 and 6 with respect to the circumferential direction A of the cylindrical surface 3 of the base 2 is the axial direction B where the side plates 6 and 6 of the base 3 are attached. By uniquely arranging the sawtooth wires 7 along the gauge surface 8 in the axial direction B, the predetermined inclination angle can be easily and stably determined without individual differences. The sawtooth wire 7 is out of alignment and arrangement in the process of keeping the pressed state against the cylindrical surface 3 of the base 2 until the adhesive 9 is solidified by the guide holding by the gauge surface 8. If the side plates 6 and 6 on both ends have the gauge surface 8, the arrangement and arrangement of the sawtooth wires 7 may be distorted or displaced by guiding and holding the sawtooth wires 7 from both sides.

The direction of the sawtooth wire 7 is regulated between 8 and arranged in the axial direction B on the adhesive application surface, and the arranged sawtooth wire 7 is bonded to the cylindrical surface 3 of the base 2 while being pressed. The step of solidifying the agent 9 and fixing the sawtooth wire 7 to the cylindrical surface 3 of the base 2 includes, in particular, the side plates 6, 6 at both ends of the gauge surface 8, 8 with sawtooth wires 7 arranged in the axial direction B parallel to both sides And obtaining the state with scissors and regulating between gauge face 8,8, or mad array or arrangement of the sawtooth wire 7, it is possible to reliably prevent or displaced.

  In the cylindrical comb 1, the sawtooth wire 7 is further arranged in the circumferential direction A by being divided into a plurality of sections C, D, E, F, etc. as shown in FIGS. 1, 2, and 5. The angle of inclination θ of the wire 7 with respect to the circumferential direction A is reversed regularly or irregularly such as every section or every suitable section as illustrated by sections C, D, E, F, etc. The gauge surface 8 of 6 corresponds to the sections C, D, E from one side in the circumferential direction A to the other side corresponding to the reversal of the inclination angle θ of the sawtooth wire 7 for each section C, D, E, F. , F can be reversed.

  In this way, the sawtooth wire 7 is divided into a plurality of sections C, D, E, F and the like in the circumferential direction A of the cylindrical surface 3 of the base 2, so that the sections C, D, E, F, etc. The inclination angle θ of the sawtooth wire 7 and the type of tooth can be selected for each, and the inclination angle θ can be reversed regularly or irregularly in order from one side section to the other side section in the circumferential direction A. In the preceding section and the following section where θ is inverted, the direction of the tooth arrangement is combined with different handling actions on the fiber running in the circumferential direction A according to the difference in the inclination angle θ, and the inclination angle on one side is combined. It is possible to eliminate or reduce the bias of the handling effect due to only θ, regular inversion can make the above compound fine and uniform, and irregular inversion removes the rules for the type of teeth etc. It can be freely handled by complex patterns.

  The side plates 6 and 6 are synthetic resin molded products, which are inferior in terms of binding force and strength with respect to the sawtooth wire 7 as compared with metal, but are not screwed as shown in FIGS. In addition to screwing at one central location using the mounting holes 12 for the attachment, the attachment is used together. However, bonding can be omitted by using a plurality of screwing points. As shown in FIGS. 3 to 5, the gauge surface 8 of the side plate 6 is an inner surface of a protruding portion 6 b that protrudes outward from the cylindrical surface 4 from the attachment portion 6 a to the end surface 4 in the base biaxial direction B of the side plate 6. In addition, the three-dimensional shape is formed so as to protrude on the cylindrical surface 3 side as shown in FIG. 3, but it can be obtained easily and at a lower cost than a metal because it is a synthetic resin molded product.
