Detailed Description
< embodiment 1 >
Fig. 1 is a partially cut-away plan view showing a structure of a spindle brake device of a spinning machine according to embodiment 1, and fig. 2 is a perspective view showing a structure of a main part of the spindle brake device of fig. 1. Fig. 3 is a perspective view showing a structure of a spindle brake device of the spinning machine according to embodiment 1.
In embodiment 1, first, a structure of a spindle device of a spinning machine will be described, and thereafter, a structure of a spindle brake device of a spinning machine according to embodiment 1 will be described. The spindle braking device is a device arranged in the accessory of the spindle device.
(Structure of spindle device)
As shown in fig. 1 to 3, a spindle device of a spinning machine includes: two spindles 11 adjacent to each other in the longitudinal direction X of the spindle guide 10, and a spindle tape 12 wound around the two spindles 11. The spindles 11 are rotated by the operation of the spindle belts 12. The spindles 11 are provided one for each spindle of the spinning machine. A bobbin (not shown) for winding the yarn is attached to the spindle 11. The spindles 11 are vertically arranged upright on the spindle guide 10. In addition, the spindle 11 has a spindle disk 13. The spindle disk 13 integrally has a small diameter portion 13a and a large diameter portion 13b, and the spindle tape 12 is wound around the small diameter portion 13a of the spindle disk 13. As shown in fig. 3, the spindle disk 13 is disposed above the flange portion 14a of the pad plate 14. Backing plate 14 is secured to spindle guide 10 by nuts 15.
The spindle belt 12 is driven by a spindle driving motor not shown. The spindle band 12 is an endless band and has moderate flexibility. The spindle band 12 is wound around the 4 spindles 11 in a set of 4 spindles out of a plurality of spindles provided in the spinning machine. However, in fig. 1 and 3, only two spindles 11 among the 4 spindles 11 belonging to the same group are shown, and the other two spindles 11 are not shown. Two spindles 11 of the 4 spindles 11 are disposed on one side in the width direction Y of the spindle guide 10, and the other two spindles 11 are disposed on the other side in the width direction Y of the spindle guide 10. Further, one spindle tape 12 is wound around the 4 spindles 11. Therefore, if the spindle belt 12 runs, 4 spindles 11 rotate in association therewith. The width direction Y of spindle guide 10 is a direction orthogonal to the longitudinal direction X of spindle guide 10.
(Structure of spindle brake device)
As shown in fig. 1 to 3, a spindle braking device 20 of a spinning machine includes a brake main body 21, a separator roller 22, a brake shoe 23, and a handle 24. The brake main body 21 is made of metal such as stainless steel. The brake main body 21 integrally has: a base block portion 26, a panel wall portion 27, and a bottom block portion 28. A part of the base block portion 26 is formed in a semicircular shape to have a notch, and the brake shoe 23 is provided in the notch. The plate wall portion 27 is formed vertically upright from one end edge of the upper surface of the base block portion 26. The upper end portion of the plate wall portion 27 is disposed at almost the same height as the upper end portion of the separation roller 22. The panel wall portion 27 is used to ensure safety of the worker. Specifically, the plate wall portion 27 prevents an operator from accidentally touching the spindle tape 12 with his or her hand when the operator grips the handle 24. The bottom block portion 28 is disposed on the lower surface side of the base block portion 26. The bottom block portion 28 protrudes downward with a narrower width than the base block portion 26. A projection 29 is integrally formed at the lowermost portion of the bottom block portion 28. The projection 29 is a portion fitted into a guide groove (described later) of the spindle guide 10.
As shown in fig. 2, the separation roller 22 is constituted by two rollers 22a, 22 b. The separation roller 22 is a roller for separating the spindle tape 12 from the spindle 11. The two rollers 22a and 22b are disposed on the upper surface side of the base block portion 26 of the brake main body 21. Each of the rollers 22a and 22b is, for example, a metal roller, and is provided to be rotatable. The rotation axes of the rollers 22a and 22b are arranged parallel to the rotation axis of the spindle 11. When the brake main body 21 is disposed at the brake standby position P1 or the brake operating position P2, the two rollers 22a and 22b are disposed in a row in the longitudinal direction X of the spindle guide 10.
Here, as shown in fig. 2, when one direction of the front-rear direction of the brake main body 21 is defined as a front side F and the opposite side thereof is defined as a rear side R, the plate wall portion 27 is disposed on the rear side R of the brake main body 21 and the brake shoe 23 is disposed on the front side F of the brake main body 21. The separation roller 22 is disposed between the plate wall portion 27 and the brake shoe 23 in the front-rear direction of the brake main body 21.
The brake shoe 23 stops the rotation of the spindle 11 by contacting the spindle 11. The brake shoe 23 is formed in an arc shape in conformity with the notch shape of the base block portion 26. The brake shoe 23 is made of a material having a large friction coefficient, such as rubber, resin, or leather. The brake shoe 23 is disposed to cover the notch portion of the base block portion 26. Therefore, the surface of the brake shoe 23 is exposed to the outside at the front side F of the brake main body 21.
The handle 24 is provided to facilitate the operation of the stopper body 21 at the time of replacement work of the stopper body 21 described later. The handle 24 is disposed to protrude toward the rear side R of the stopper body 21. The handle 24 integrally has a shaft portion 24a and a grip portion 24 b. One end of the shaft portion 24a is fixed to the base block portion 26 of the brake main body 21 by fastening, press-fitting, bonding, or the like with screws, for example. The grip portion 24b is provided at a distal end portion of the shaft portion 24 a. The grip portion 24b is formed with a larger outer diameter than the shaft portion 24a in consideration of the ease of gripping of the handle 24.
As shown in fig. 1 and 3, the spindle rail 10 is provided with a brake standby position P1 and a brake operating position P2. The brake standby position P1 is a position where the brake main body 21 is caused to stand by without applying a braking force to both the spindles 11, and the brake operating position P2 is a position where the brake main body 21 is disposed for applying a braking force to either one of the two spindles 11. Brake standby position P1 is set at a position shifted from spindle 11 in longitudinal direction X of spindle guide 10, and brake operating position P2 is set at the same position as spindle 11 in longitudinal direction X of spindle guide 10. The stopper standby position P1 is set such that the stopper main body 21 is positioned between two spindles 11 in the longitudinal direction X of the spindle guide 10. The brake operating position P2 is set such that the brake main body 21 faces each of the two spindles 11 in the width direction Y of the spindle guide 10. The brake operating position P2 is set on both sides of the brake standby position P1 with the brake standby position P1 in between.
The guide groove 31 is formed at the brake standby position P1, and the guide grooves 32 are formed at the brake operating positions P2 on both sides thereof. The guide groove 31 and the guide groove 32 constitute a guide portion that guides the stopper body 21 to be movable in the width direction Y of the spindle guide 10. Guide grooves 31 and 32 are formed on the upper surface of spindle guide 10. As shown in fig. 3, the guide grooves 31 and 32 are formed in a dovetail groove shape having a trapezoidal cross section.
In contrast, the stopper body 21 is configured to be movable in the width direction Y of the spindle guide 10 by fitting the protrusion 29 of the bottom block 28 into the guide groove 31 or the guide groove 32 of the spindle guide 10. The projection 29 of the bottom block 28 is insertable into and removable from the guide groove 31 and also insertable into and removable from the guide groove 32 in the width direction Y of the spindle guide 10. Thus, the brake main body 21 can be disposed at either the brake standby position P1 or the brake operating position P2.
(operation of spindle brake device)
Next, the operation of the spindle brake device 20 according to embodiment 1 will be described.
First, as shown in fig. 1 and 3, when no braking force is applied to both spindles 11, the protrusion 29 of the bottom block 28 is fitted into the guide groove 31 of the spindle guide 10, and the brake main body 21 is disposed at the brake standby position P1. At this time, the position of the stopper body 21 in the longitudinal direction X of the spindle guide 10 is determined by fitting the protrusion 29 and the guide groove 31. The position of the stopper body 21 in the width direction Y of the spindle guide 10 is determined by the end of the protrusion 29 abutting the end of the guide groove 31. Thereby, the brake main body 21 is positioned at the brake standby position P1. In the state where the brake main body 21 is disposed at the brake standby position P1 in this manner, the separation roller 22 is disposed inside the spindle tape 12 so as to be spaced apart from the spindle tape 12. Further, the spindle tape 12 is wound around the two spindles 11 by passing between the separation roller 22 and the plate wall portion 27. Therefore, when the spindle belt 12 is driven by a spindle driving motor not shown, the respective spindles 11 are rotated in accordance with the movement of the spindle belt 12.
Here, when a yarn breakage occurs at any spindle during the spinning of the yarn, the rotation of the spindle 11 is stopped at the spindle where the yarn breakage occurs, and the broken yarn is connected by the yarn joining, and then the rotation of the spindle 11 is restarted. Therefore, for example, when a yarn breakage occurs in a spindle provided with the right spindle 11 of the two spindles 11 shown in fig. 1, the brake main body 21 is moved from the brake standby position P1 to the right brake operating position P2 by an operation of replacing the brake main body 21 by an operator. The movement sequence of the stopper body 21 at this time is as follows.
First, the operator grips the handle 24 and pulls the stopper body 21 forward, i.e., in the direction Y1 of fig. 1. Thereby, the brake main body 21 moves in the Y1 direction while being guided by the guide groove 31. The two rollers 22a and 22b constituting the separation roller 22 are brought into contact with the ingot belt 12 by pulling in the brake main body 21. Thereby, the separation roller 22 is rotated by the operation of the spindle tape 12. At this time, the operator pulls in the brake main body 21 in the Y1 direction against the tension of the spindle band 12 until the protrusion 29 is disengaged from the guide groove 31.
Next, the operator shifts the position of the stopper body 21 to the right in fig. 1 while holding the handle 24, thereby aligning the position of the protrusion 29 with the guide groove 32. Next, the operator inserts the protrusion 29 into the guide groove 32 and moves the brake main body 21 to the depth side of the guide groove 32 by the tension of the spindle band 12, thereby bringing the brake shoe 23 into contact with the large diameter portion 13b of the spindle disk 13. At this time, the position of the stopper body 21 in the longitudinal direction X of the spindle guide 10 is determined by fitting the protrusion 29 into the guide groove 32. The position of the brake main body 21 in the width direction Y of the spindle guide 10 is determined by the brake shoe 23 abutting against the large diameter portion 13b of the spindle disk 13. Thereby, the brake main body 21 is positioned at the brake operating position P2. As shown in fig. 4 and 5, in the state where the brake main body 21 is disposed at the brake operating position P2 in this way, the spindle where the yarn breakage occurs is wound around the spindle 12 on the separator roller 22. Therefore, the spindle tape 12 is disposed away from the spindle 11 for the spindle in which the yarn breakage occurs. Therefore, the power transmission from the spindle tape 12 to the spindle 11 is disconnected.
On the other hand, the brake shoe 23 is pressed against the spindle 11 by the tension of the spindle band 12. Specifically, a pressing force in the Y2 direction is applied to the separation roller 22 by the tension of the spindle tape 12, and the brake shoe 23 is pressed against the large diameter portion 13b of the spindle disk 13 by the pressing force. Therefore, in the spindle in which the yarn breakage occurs, the spindle 11 is applied with a braking force due to the frictional resistance generated at the contact surface between the brake shoe 23 and the spindle disk 13. This can stop the rotation of the spindle 11 for the spindle in which the yarn breakage occurs. In addition, the spindle 11 can continue to rotate for the spindle in which the yarn breakage does not occur.
Further, it is also conceivable that, when a pushing force is applied to the separation roller 22 by the tension of the ingot belt 12 as described above, the rear side R (see fig. 2) of the stopper body 21 is lifted by the pushing force, and the stopper body 21 falls down. In this regard, in embodiment 1, a dovetail groove-shaped guide groove 32 is formed in the spindle guide 10, and the protrusion 29 of the stopper body 21 is fitted into the guide groove 32. Therefore, the falling of the brake main body 21 can be suppressed by fitting the guide groove 32 and the projection 29. Therefore, even if the operator separates his/her hand from the handle 24, the state in which the spindle tape 12 is separated from the spindle 11 by the separation roller 22 and the brake shoe 23 is pressed against the spindle 11, that is, the state in fig. 4 can be maintained. Therefore, when the yarn splicing is performed by the manual operation of the operator, the operator can freely perform the yarn splicing operation using both hands.
When the yarn joining is completed at the spindle where the yarn breakage has occurred, the brake main body 21 is moved from the brake application position P2 to the brake standby position P1 in the reverse order to the above-described order, and the state of fig. 1 is returned. This enables the spindle 11 to resume rotation when the yarn joining operation is completed. When a yarn breakage occurs in the spindle having the left spindle 11 in fig. 1, the rotation of the spindle 11 can be stopped at the spindle where the yarn breakage occurs by moving the brake main body 21 from the brake standby position P1 to the left brake operating position P2 in the same manner as described above.
In the spindle brake device 20 according to embodiment 1, the brake shoe 23 can be pressed against the spindle 11 while the spindle tape 12 is separated from the spindle 11 only by providing the brake main body 21 with the separator roller 22 and the brake shoe 23 and moving the brake main body 21 from the brake standby position P1 to the brake operating position P2. Further, since the brake shoe 23 is pressed against the spindle 11 by the tension of the spindle band 12, the structure for pressing the brake shoe against the spindle is simplified as compared with the spindle brake devices described in patent documents 2 and 3. As a result, the spindle brake device 20 can be realized with a simpler configuration than the spindle brake devices described in patent documents 2 and 3.
In the spindle brake device 20 according to embodiment 1, since the brake shoes 23 are pressed against the spindles 11 by the tension of the spindle belts 12, it is possible to press the brake shoes 23 against the spindles 11 with a stable pressing force without requiring a troublesome operation for pressing. In addition, since the brake main body 21 always stands by at the brake standby position P1 in a normal state in which no yarn breakage occurs, the operator can quickly stop the spindle 11 and start the yarn splicing operation without carrying a tool for spindle braking with him or taking it back. This can shorten the time required from the occurrence of yarn breakage to the termination of the yarn joining operation. Therefore, a decrease in productivity due to yarn breakage can be suppressed. Further, the rotation of the two spindles 11 aligned in the longitudinal direction X of the spindle guide 10 can be stopped using one spindle brake device 20. This can reduce the number of spindle brake devices required, compared to a case where one spindle brake device is provided for each spindle 11.
< embodiment 2 >
Fig. 6 is a perspective view showing a structure of a spindle braking device of the spinning machine according to embodiment 2, and fig. 7 is a side view showing the structure of the spindle braking device. In fig. 6 and 7, the spindle tape 12 is not shown. In embodiment 2, the same reference numerals are given to the same or corresponding portions as those in embodiment 1.
The spindle brake device 20 according to embodiment 2 differs from embodiment 1 in the shape of the guide grooves 31 and 32 formed as guide portions in the spindle guide 10, the shape of the brake body 121 fitted therein, and the mounting of the bracket 35 to the brake body 121.
The guide groove 31 and the guide groove 32 are formed to have a rectangular cross section when viewed in the width direction Y of the spindle guide 10. In contrast, the bottom block portion 128 of the stopper body 121 is formed in a rectangular shape as viewed in the width direction Y of the spindle guide 10. In the width direction Y of the spindle guide 10, the width dimension of the guide groove 31 is set to be the same as the width dimension of the guide groove 32, and the width dimension of the bottom block 128 is set to be slightly smaller than the width dimension of the guide groove 31. In the brake standby position P1, as shown in fig. 6, the lower portion of the bottom block 128 is fitted into the guide groove 31, and in the brake operating position P2, the lower portion of the bottom block 128 is fitted into the guide groove 32, as shown in fig. 8 and 9.
The bracket 35 integrally has: a substantially U-shaped grip portion 36, an engaging portion 37 extending from an intermediate portion of the grip portion 36, and a locking portion 38 bent at a right angle from an extending end of the engaging portion 37. The grip 36 is formed on the upper portion of the bracket 35. The grip 36 is arranged to grip the bottom block 128 from both sides in the longitudinal direction X of the spindle rail 10. The grip portion 36 is rotatably supported by the support member 39 on both sides of the bottom block portion 128. The engaging portion 37 is formed with a width slightly smaller than the width dimension of the guide groove 31 so as to be engageable with the guide groove 31 of the spindle guide 10. The engaging portion 37 is a portion that positions the stopper body 121 in the longitudinal direction X of the spindle guide 10 by engaging with the guide groove 31 when the stopper body 121 is disposed at the stopper standby position P1. The locking portion 38 is formed at a lower portion of the bracket 35. The locking portion 38 is a portion that suppresses falling of the brake main body 121 due to tension of the spindle tape 12 by locking with the locked portion 10a on the lower surface side of the spindle guide 10 when the brake main body 121 is disposed at the brake operating position P2.
In the spindle brake device 20 according to embodiment 2, when the brake main body 121 is disposed at the brake standby position P1, the lower portion of the bottom block 128 of the brake main body 121 is fitted into the guide groove 31, and the end of the bottom block 128 abuts against the end of the guide groove 31. At this time, the position of the stopper body 121 in the width direction Y of the spindle guide 10 is determined by the contact between the end of the guide groove 31 and the end of the bottom block 128. As shown in fig. 6 and 7, the position of the stopper body 121 in the longitudinal direction X of the spindle guide 10 is determined by the engagement of the engagement portion 37 of the bracket 35 with the edge portion of the guide groove 31. Thereby, the brake main body 121 is positioned at the brake standby position P1. In the state where the brake main body 121 is disposed at the brake standby position P1 in this manner, the spindle tapes 12 are wound around the two spindles 11 through the gap between the separation roller 22 and the plate wall portion 27, as in the above-described embodiment 1. Therefore, when the spindle belt 12 is driven by a spindle driving motor not shown, the respective spindles 11 are rotated by the operation of the spindle belt 12.
On the other hand, when the stopper body 121 is moved from the stopper standby position P1 to the stopper operating position P2, the stopper body 121 is separated from the guide groove 31 by the operator gripping the handle 24 and pulling the stopper body 121 to the front side, as in the above-described embodiment 1. At this time, the bracket 35 rotates counterclockwise in fig. 7 about the position of the support member 39. Next, as shown in fig. 8 and 9, the worker holds the handle 24 and fits the lower portion of the bottom block 128 into the guide groove 32, and moves the stopper body 121 to the depth side of the guide groove 32 by the tension of the spindle band 12, thereby bringing the stopper shoe 23 into contact with the large diameter portion 13b of the spindle disk 13. At this time, the position of the stopper body 121 in the longitudinal direction X of the spindle guide 10 is determined by the fitting between the bottom block 128 and the guide groove 32. The position of the brake main body 121 in the width direction Y of the spindle guide 10 is determined by the brake shoe 23 abutting against the large diameter portion 13b of the spindle disk 13. Thereby, the brake main body 121 is positioned at the brake operating position P2. In the state where the brake main body 121 is disposed at the brake operating position P2 in this manner, the spindle tape 12 is wound around the separator roller 22, and therefore, the power transmission from the spindle tape 12 to the spindles 11 is interrupted. On the other hand, the brake shoe 23 is pressed against the large diameter portion 13b of the spindle disk 13 by a pressing force applied to the separation roller 22 by the tension of the spindle tape 12. Therefore, the rotation of the spindle 11 can be stopped by the frictional resistance generated at the contact surface between the brake shoe 23 and the spindle disk 13.
Further, as described above, when the separation roller 22 is pressed by the tension of the ingot belt 12, the rear side R (see fig. 9) of the stopper body 121 may be lifted by the pressing force, and the stopper body 121 may be lowered. In this regard, in embodiment 2, when the brake main body 121 is disposed at the brake operating position P2, as shown in fig. 9, the locking portion 38 of the bracket 35 is locked to the spindle rail 10, whereby falling of the brake main body 121 can be suppressed. Therefore, even if the operator separates the hand from the handle 24, the state in which the spindle band 12 and the spindle 11 are separated by the separation roller 22 and the brake shoe 23 is pressed against the spindle 11, that is, the state in fig. 8 can be maintained. Therefore, when the yarn splicing is performed by the manual operation of the operator, the operator can freely perform the yarn splicing operation using both hands.
< embodiment 3 >
Fig. 10 is a perspective view showing a configuration of a main part of the spindle brake device according to embodiment 3. In embodiment 3, the same reference numerals are given to the same or corresponding portions as those in embodiment 1.
As shown in fig. 10, a positioning pin 41 is provided on the stopper main body 221. In addition, a fitting portion 30 protruding downward is integrally formed on the bottom block portion 228 of the stopper main body 221. The fitting portion 30 is integrally formed at the lowermost portion of the bottom block portion 228. The fitting portion 30 is a portion fitted into the guide groove 31 of the spindle guide 10. The positioning pin 41 is configured to be able to be inserted into and removed from a positioning hole described later. The positioning pin 41 is disposed to protrude toward the front side F of the stopper body 221. The positioning pin 41 is fixed to the fitting portion 30 of the bottom block 228 by press fitting, adhesion, or the like, for example. The distal end portion of the positioning pin 41 is formed in a tapered shape by chamfering or the like so that the positioning pin 41 can be easily inserted into a positioning hole described later.
As shown in fig. 11, on the other hand, spindle guide 10 has guide groove 31 formed at brake standby position P1, and has positioning hole 42 formed at brake operating position P2. The positioning hole 42 is provided at the stopper operating position P2 as a guide portion for guiding the stopper body 221 to be movable in the width direction Y of the spindle guide 10. Positioning holes 42 are formed in spindle guide 10 corresponding to positioning pins 41 described above. The positioning hole 42 is formed with an inner diameter slightly larger than the outer diameter of the positioning pin 41 so as to allow the positioning pin 41 to be inserted and removed.
In the spindle brake device 20 according to embodiment 3, when the brake main body 221 is disposed at the brake standby position P1, the fitting portion 30 of the bottom block portion 228 is fitted into the guide groove 31, and the end of the fitting portion 30 abuts against the end of the guide groove 31. At this time, the position of the stopper main body 221 in the longitudinal direction X of the spindle guide 10 is determined by the fitting between the fitting portion 30 and the guide groove 31. The position of the stopper body 221 in the width direction Y of the spindle guide 10 is determined by the contact between the end of the guide groove 31 and the end of the fitting portion 30. Thereby, the brake main body 221 is positioned at the brake standby position P1. In the state where the brake main body 221 is disposed at the brake standby position P1, the spindle tape 12 is wound around the two spindles 11 through the gap between the separation roller 22 and the plate wall portion 27, as in the above-described embodiment 1. Therefore, when the spindle belt 12 is driven by a spindle driving motor not shown, the spindles 11 are rotated by the operation of the spindle belt 12.
On the other hand, when the stopper main body 221 is moved from the stopper standby position P1 to the stopper operating position P2, the operator grasps the handle 24 and pulls the stopper main body 221 forward, thereby disengaging the stopper main body 221 from the guide groove 31, as in the case of the above-described embodiment 1. Next, the worker inserts positioning pins 41 into positioning holes 42 while holding handle 24 as shown in fig. 12, and moves brake main body 221 to the depth side of guide groove 32 by the tension of spindle band 12, thereby bringing brake shoe 23 into contact with large diameter portion 13b of spindle disk 13. At this time, the position of the stopper body 221 in the longitudinal direction X of the spindle guide 10 is determined by fitting the positioning pin 41 into the positioning hole 42. The position of the stopper body 221 in the width direction Y of the spindle guide 10 is determined by the contact of the brake shoe 23 with the large diameter portion 13b of the spindle disk 13. Thereby, the brake main body 221 is positioned at the brake operating position P2. In the state where the brake main body 221 is disposed at the brake operating position P2 in this manner, the spindle tape 12 is wound around the separator roller 22, and therefore, the power transmission from the spindle tape 12 to the spindles 11 is interrupted. On the other hand, the brake shoe 23 is pressed against the large diameter portion 13b of the spindle disk 13 by a pressing force applied to the separation roller 22 by the tension of the spindle tape 12. Therefore, the rotation of the spindle 11 can be stopped by the frictional resistance generated by the contact surface of the brake shoe 23 and the spindle disk 13.
Further, as described above, when the pushing force is applied to the separation roller 22 by the tension of the ingot belt 12, the rear side R (see fig. 12) of the stopper main body 221 may be lifted by the pushing force, and the stopper main body 221 may fall down. In this regard, in embodiment 3, when the stopper body 221 is disposed at the stopper operating position P2, the positioning pin 41 is inserted into the positioning hole 42, and thereby the falling of the stopper body 221 can be suppressed. Therefore, even if the operator separates the hand from the handle 24, the state in which the spindle tape 12 is separated from the spindle 11 by the separation roller 22 and the brake shoe 23 is pressed against the spindle 11 can be maintained. Therefore, when the yarn splicing is performed by the manual operation of the operator, the operator can freely perform the yarn splicing operation using both hands.
