Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an application device capable of uniformly applying a smoothing agent such as paraffin to a supply yarn in an active yarn supply device for supplying a yarn to a circular knitting machine or the like.

[0002]

2. Description of the Related Art In a knitting process of a knitting machine such as a circular knitting machine, from the viewpoint of securing stable productivity and obtaining a high-quality knitted fabric product, the yarn to be supplied has excellent smoothness.
That is, it is required that the surface friction of the yarn be minimized at the place where the yarn comes into contact during the knitting process. In response to such a demand, conventionally, knitting is generally performed using a yarn in which a smoothing agent such as paraffin has been previously applied to the surface thereof as a supply yarn. That is, prior to the knitting process of the knitting machine, it is common to apply a smoothing agent such as paraffin to the supply yarn in advance when performing a winding operation on the supply yarn by a winder in a process different from the knitting process. It was a target. Specifically, as shown in FIG. 8, during the process of rewinding the supply raw yarn by a winder, the supply raw yarn (100) is rotated freely by a solid paraffin disk (101) and a tension disk (102). ), The solid paraffin disk body (101) is driven to rotate with the movement of the supply yarn (100), whereby the supply yarn (100) This is to give paraffin to the surface.

[0003]

However, in the above-mentioned prior art, the smoothing agent is applied in a step separate from the knitting step of the knitting machine, and therefore the number of steps is increased. , And production costs were also high.

[0004] The addition of paraffin to the supply yarn is
Since the disk body made of solid paraffin is driven and rotated with the movement of the supply yarn,
There is naturally a limit in the amount of application, and there is also a problem that paraffin cannot be sufficiently applied to the yarn.
Furthermore, since the solid paraffin disk body is driven to rotate, the rotation of the disk body is not constant, causing rotation unevenness, and it is impossible to apply paraffin uniformly to the yarn. Therefore, it is difficult to secure uniform smoothness at any point in the supplied raw yarn, and there is also a problem that stable productivity and high quality as a knitted fabric product cannot be secured.
In addition, since the rotation of the solid paraffin disk could not be constant, the precision of the amount of the smoothing agent applied was also inferior.

The present invention has been made in view of such a technical background, and it is possible to uniformly apply a smoothing agent such as paraffin to a supply yarn without unevenness, and to accurately control the amount of the smoothing agent applied. It is an object of the present invention to provide a smoothing agent applying device capable of performing the above-described operations.

[0006]

Means for Solving the Problems In order to achieve the above object, the present inventors have made intensive studies and found that solid paraffin is interlocked with the rotation of a rotating shaft to which a rotational driving force is transmitted from an external rotating driving means. And the like, so as to rotate the flattening plate, and face each other with the flattening plate interposed therebetween.
By arranging a yarn introduction guide hole at one of the two confronting positions and a yarn derivation guide hole at the other, so that the yarn is in contact with the surface of the smoothing agent plate between the two guide holes,
The inventors have found that the above-described desired leveling agent applying apparatus can be obtained, and have completed the present invention.

That is, the smoothing agent applying apparatus according to the present invention comprises:
A rotating shaft to which a rotational driving force from an external rotating driving means is transmitted, a support for pivotally supporting the rotating shaft, and a smoothing agent such as solid paraffin that is configured to rotate in conjunction with the rotation of the rotating shaft. A plate-like body, a yarn introduction guide hole provided at one of two facing positions facing each other with the smoothing agent plate-like body therebetween, and a yarn lead-out provided at the other of the facing positions. And a guide hole, wherein the yarn passing through the yarn introduction guide hole is brought into contact with the surface of the smoothing agent plate before reaching the yarn lead-out guide hole. It is assumed that.

Since the yarn is brought into contact with the surface of the flattening plate during the time from the yarn introduction guide hole to the yarn deriving guide hole, the yarn is brought into contact with the surface of the flattening plate in the operating state. The sliding contact makes it possible to impart a smoothing agent to the yarn by such sliding contact. At this time, since the smoothing agent plate is rotated in conjunction with the rotation of the rotating shaft, the smoothing agent plate is stably rotating at a constant speed. Therefore, the smoothing agent can be evenly and uniformly applied to the supply yarn, uniform smoothness can be applied to any part of the supply yarn, and the applied amount can be accurately controlled to a constant amount.

It is preferable that the flattening plate is configured to rotate about the rotation axis, and is arranged in parallel with a plane orthogonal to the axial direction of the rotation axis. Since the smoothing agent plate is configured to rotate about a rotation axis to which rotation driving force from an external rotation driving unit is transmitted, that is, the rotation agent is not rotated through another interlocking mechanism. Since it is provided directly, it is possible to sufficiently reduce the size of the device. In addition, since the smoothing agent plate is disposed parallel to a plane orthogonal to the axial direction of the rotation axis, the surface of the plate and the rotation horizontal plane thereof coincide with or substantially coincide with each other, and therefore, the yarn Can be brought into contact with the surface of the plate-like body in a uniform state at any position of the plate-like body, and the smoothing agent can be evenly and uniformly applied to the supply yarn.

It is preferable that the position of the yarn introducing guide hole and the yarn deriving guide hole facing each other can be freely changed about the center of rotation of the smoothing agent plate.
By changing the relative opposing position, the length (distance) of the yarn in contact with the surface of the flattening agent plate can be arbitrarily set, and the amount of the smoothing agent applied can be appropriately adjusted. Thus, there is an advantage that the level of the smoothing agent can be controlled over a wide range from a low level to a high level.

[0011] It is preferable that the above-mentioned rotary shaft is constituted by using a rotary shaft for rotationally driving a yarn feed rotary body of a positive yarn feeding device. With such a configuration, it is possible to apply the smoothing agent to the supply yarn at the same time as performing the active yarn supply, so that it is extremely efficient, and the equipment cost as an apparatus for applying the smoothing agent is also reduced. Reduced.

In the above, it is preferable that a belt wheel is provided around the rotation shaft, and the rotation driving force from an external rotation driving means is transmitted to the rotation shaft by a belt transmission mechanism. With such a configuration, a more stable rotation drive can be transmitted, so that the smoothing agent can be more uniformly applied to the supply yarn.

[0013]

A plurality of ridges (15a) are provided on the outer peripheral surface of the belt wheel (15) in parallel along the rotation center axis direction. Thus, one end of an endless V-belt (not shown) is fitted on the outer peripheral surface of the belt wheel (15), and a V-shaped ridge on the inner peripheral surface of the belt is fitted between the ridges (15a). If the other end is mounted on a rotary drive shaft of an external rotary drive unit (not shown), the rotational driving force from the rotary drive unit is applied to the belt wheel (15) and the rotary shaft (3). ) Can be transmitted to the yarn feed rotary body (2), and thus the yarn feed rotary body (2) can be driven to rotate at a desired rotation speed.

At the right end of the support (4), a freely rotating guide roller (18) for guiding the yarn to the yarn feed rotating body (2) is projected and provided. ) A first thread guide bar (19) is attached so as to extend in the lower right direction from below the right end. A first yarn guide hole (20) is provided at the tip of the first yarn guide bar (19), so that the yarn guided by the guide roller (18) can be fed to the yarn feed rotary member (2). ). Further, a guide ring (21) protrudes downward from the lower surface of the support (4) at a position on the left side of the yarn feed rotary body (2). The guide ring (21) is for guiding the yarn actively fed from the yarn feed rotary body (2) to a knitting position of a knitting machine or the like. Reference numeral (41) denotes a yarn break sensor, which detects when the yarn supplied to the yarn feed rotary member (2) is absent due to cutting or the like or when the yarn tension is abnormally reduced. It is for detecting.

A substantially disk-shaped support plate (40) is attached and fixed to the other end of the rotary shaft (3).
On the upper surface of 0), a smoothing plate-like body (6) made of solid paraffin or the like having a circular disk shape is placed. That is, the rotating shaft (3) is placed on the support plate (40) in a state where the rotary shaft (3) is loosely fitted in the insertion hole (6a) provided in the center of the smoothing agent plate (6). Then, when the rotation driving force from the external rotation driving means is transmitted through the belt wheel (15) and the rotation shaft (3) rotates, the support plate (4) fixed thereto is rotated.
0) also rotates, and the flattening plate (6) placed on the support plate (40) also rotates synchronously with the rotation.

Further, the lower end of the inverted L-shaped thread introduction guide bar (12) is screwed and fixed to the center of the upper surface of the support (4), while the right edge of the upper surface of the support (4) is fixed. The lower ends of the thread discharge guide bars (13) are fixed by screws, and both guide bars (12) and (13) are fixed to the flattening plate (6).
Are arranged so as to face each other. A yarn introduction guide hole (10) is provided in the yarn introduction guide bar (12) at an extended position of the flattening agent plate (6) in a substantially rotational horizontal direction, and a yarn discharge guide bar (1).
A thread leading guide hole (11) is provided at an extended position of the flattening agent plate (6) in the substantially horizontal direction in 3), and both the guide holes (10) and (11) are provided with the flattening agent plate ( 6)
Are arranged so as to face each other. Also,
A thread introduction assisting guide hole (14) is provided at a bent end portion of the thread introduction guide bar (12).

The yarn (X) supplied to the smoothing agent applying device (1) is first inserted into the yarn introduction guide hole (14), and then into the yarn introduction guide hole (10). The feed yarn (X) is inserted through the yarn guiding guide hole (11) and then from the yarn introducing guide hole (10) to the yarn guiding guide hole (11). Are arranged so as to come into contact with the surface of the smoothing plate (6). That is, the supply yarn (X) is inserted between the support plate (40) and the flattening agent plate (6). Therefore, in the yarn feeding operation state, the yarn (X) reaches the yarn lead-out guide hole (11) while slidingly contacting the surface of the smoothing agent plate (6). Sliding contact with (6) makes it possible to impart a smoothing agent to the yarn (X).

At this time, the flattening plate (6) itself is driven by the rotation of the support plate (40) fixedly connected to the rotating shaft (3) to which the rotational driving force from the external rotational driving means is transmitted. Is tuned. What can be tuned and rotated like this is
This is because the yarn is conducted between the upper surface of the support plate (40) and the lower surface of the smoothing agent plate (6), but a sufficient contact portion exists between the both (40) and (6). Thus, when the yarn (X) comes into sliding contact with the surface of the flattening plate (6), the flattening plate (6) is stably rotated at a constant speed. In addition, the smoothing agent can be uniformly applied to the supply yarn (X) without unevenness, so that the supply yarn (X) can be provided with uniform smoothness at any position, and thus stable productivity can be secured. At the same time, it enables the production of high-quality knitted fabric products. In addition, since the smoothing agent plate (6) rotates stably at a constant speed, the amount of the smoothing agent applied can be accurately controlled to a constant amount. In the drawings such as FIG. 5 and the like, the solid arrow direction indicates the moving direction of the yarn (X), and the dotted arrow direction indicates the rotation direction of the smoothing agent plate (6).

Next, the yarn (X) having passed through the yarn guide hole (11) is guided by a guide roller (18) and a first yarn guide hole (20). After being wound up in 2) and wound a predetermined number of times, it is led out to a guide ring (21), and is actively fed to a knitting position of a knitting machine or the like while being guided by the guide ring (21).

In this embodiment, the lower end of the thread introduction guide bar (12) is fixedly screwed to the support (4), and the lower end of the thread guide guide bar (13) is supported by the support (4). ). Accordingly, the fixing angles of the guide bars (12) and (13) can be easily changed by loosening these screws if necessary. For example, as shown in FIG. 7, if the respective fixing positions are changed around the rotation axis (3), that is, about the rotation center of the flattening agent plate (6), and the screws are fixed again, the thread ( It is possible to increase the length (distance) of X) in contact with the surface (6) of the flattening agent plate, thereby increasing the amount of the smoothing agent applied to the yarn. In this manner, the relative position of the yarn introduction guide hole (10) and the yarn derivation guide hole (11) can be freely changed about the rotation center of the smoothing agent plate (6). Therefore, the length (distance) in contact with the surface of the smoothing plate (6) can be arbitrarily set, and the smoothing agent application amount can be easily adjusted to a desired amount easily. is there.

It is to be noted that, instead of the above-described screw fixing, for example, a configuration is also possible in which the guide bars (12) and (13) are fixed by a fixing means having an angle switching mechanism capable of switching the fixing angle in a stepwise manner. It goes without saying that it is good.

In this embodiment, a belt transmission mechanism is employed as a transmission means for transmitting the rotational driving force from the external rotary driving means to the rotary shaft (3). The present invention is not limited to this, and other transmission mechanisms may be employed.

Further, in the present embodiment, the yarn feed rotary member (2) and the flattening agent plate (6) are rotated with respect to a single rotary shaft to which a rotary driving force from an external rotary drive unit is transmitted. However, the present invention is not particularly limited to such a configuration. For example, the rotating shaft (3) is composed of two separate shaft members of a main rotating shaft and a slave rotating shaft, and The shaft is driven to rotate in synchronization with the rotation of the main rotary shaft via a gear type transmission mechanism, and the yarn feed rotary body (2) is fixed to the main rotary shaft, while being smoothed to the slave rotary shaft. A configuration in which the agent plate-like body (6) is arranged may be used. In this case, it is also possible to set the number of rotations of the slave rotation shaft per unit time to a value different from that of the main rotation shaft. Furthermore,
The yarn feed rotary body (2) may also be configured to be fixed to another auxiliary rotary shaft that is driven to rotate in synchronization with the rotation of the main rotary shaft via, for example, a gear type transmission mechanism. .
However, it is preferable that the rotating shaft be constituted by a single shaft as in the present embodiment in that the size of the device can be avoided as much as possible, and the device can be sufficiently compact.

In the present embodiment, the flattening agent plate (6) is attached to the support plate (4) fixed to the rotating shaft (3).
0), the support plate (4)
0), but is not particularly limited to such a configuration. For example, the smoothing plate (6) is adhered and fixed to the support plate (40) and the smoothing agent is The thread may be in contact with the upper surface of the plate-like body (6), or the rotating shaft (3) is fitted into the through-hole (6a) of the smoothing plate-like body without providing a support plate. The plate-like body (6) may be fixed to the rotating shaft (3) by being squeezed. In short, the smoothing plate (6)
Is only required to rotate in conjunction with the rotation of the rotation shaft (3), and specific means adopted for that purpose is not particularly limited.

Further, in this embodiment, the moving direction of the yarn (X) and the rotating direction of the flattener plate (6) coincide with each other (see FIG. 5). However, the present invention is not limited to this. That is, the moving direction of the yarn (X) and the rotating direction of the flattening plate (6) may be reversed. In this case, the resistance increases, and the smoothing agent is applied to the yarn (X). The applied amount can be increased.

The flattening agent constituting the flattening plate (6) used in the present invention is not particularly limited as long as it can impart smoothness to the yarn (X). Solid wax and the like. Further, the shape of the smoothing agent plate (6) is desirably a circular disk shape from the viewpoint of more evenly applying the smoothing agent.

The smoothing agent applying apparatus according to the present invention is not particularly limited to the above embodiment, and various design modifications can be made as appropriate without departing from the technical idea of the present invention.

[0030]

As described above, the smoothing agent applying apparatus according to the present invention is arranged such that the yarn comes into contact with the surface of the flattening plate between the yarn introducing guide hole and the yarn leading guide hole. Thus, in the operation state of the device, the yarn is in sliding contact with the surface of the smoothing plate, and the sliding contact can apply the smoothing agent to the yarn. At this time, the smoothing agent plate is rotated in conjunction with the rotation of the rotating shaft, and the smoothing agent plate is stably rotated at a constant speed regardless of the sliding contact of the yarn. Therefore, the smoothing agent can be uniformly applied to the yarn without unevenness. Therefore, it is possible to impart uniform smoothness to the supply yarn at any point, and thereby secure stable productivity in knitting of the knitting machine and to manufacture a high-quality knitted fabric product. It can be. In addition, since the flattening agent is stably rotated at a constant speed, the applied amount of the flattening agent can be accurately controlled to a constant value.

In the case where the flattening agent plate is configured to rotate about the rotation axis and is arranged in parallel with a plane perpendicular to the axial direction of the rotation shaft, the compactness of the apparatus is reduced. In addition to being able to achieve sufficient, the smoothing agent can be more evenly applied to the supply yarn.

When the relative position of the yarn introduction guide hole and the yarn derivation guide hole can be freely changed about the center of rotation of the smoothing agent plate, such relative opposition positions are possible. By changing the length, it is possible to arbitrarily set the length (distance) at which the yarn is in contact with the surface of the smoothing agent plate, and it is possible to easily adjust the smoothing agent application amount to a desired amount appropriately. In addition, the amount of the smoothing agent applied can be controlled over a wide range from a low applied amount to a high applied amount.

In the case where a rotary shaft for rotating the yarn feed rotary body of the positive yarn feeding device is used as the rotary shaft, it is possible to apply the smoothing agent uniformly to the supply yarn while performing the positive yarn feeding. Since it is possible, there is no need to previously apply a smoothing agent to the yarn in a separate step from the knitting step as in the related art, and the number of steps can be reduced, and thus the productivity and labor saving can be sufficiently achieved, It can also contribute to a reduction in production costs.

In the case where a belt wheel is provided around the rotating shaft as driving means for the rotating shaft and the belt driving mechanism transmits the rotating driving force from the external rotating driving device to the rotating shaft, Since a more stable rotation drive can be transmitted to the rotating shaft, the smoothing agent can be more uniformly applied to the supply yarn.
