Description

Technical Field

[0001] This invention relates to a conveying device, and more particularly to a textile thread positioning device. Background Technology

[0002] In textile operations, it is necessary to position the unwound and fed textile threads, especially when there are multiple threads. These threads need to be separated to prevent tangling during use. Therefore, modern textile machines are equipped with thread positioning devices to smoothly guide multiple threads out. However, textile operations often require different types of threads or combinations of multiple threads depending on the specific needs. In such cases, current methods typically involve first winding the multiple threads together and then unwinding them to the positioning device. This approach is inflexible and cumbersome. Therefore, current thread positioning devices are functionally limited and cannot meet diverse usage requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a textile thread positioning device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this invention is:

[0005] A textile thread positioning device includes: a thread separating disc with its center line extending in a left-right direction, and a plurality of thread separating grooves arranged around the outer peripheral wall of the thread separating disc; and a thread combining unit, which includes a mounting frame, a thread combining drive, and a thread combining block. The mounting frame is connected to the outer peripheral wall of the thread separating disc, and the thread combining drive is connected to the mounting frame. The thread combining drive drives the thread combining block to move radially along the thread separating disc, causing the limiting groove to move closer to or away from the center line of the thread separating disc. There are multiple thread combining units, and the distances between the multiple thread combining blocks and the thread separating disc are different. The limiting grooves on the multiple thread combining blocks are one-to-one opposite to the multiple thread separating grooves in the left-right direction.

[0006] This technical solution has at least the following beneficial effects: During the feeding and positioning of textile threads, multiple textile threads are fed through the dividing disc. At this time, the multiple textile threads are arranged one-to-one and pass through multiple dividing grooves on the outer peripheral wall of the dividing disc. These grooves separate and position the different textile threads, effectively reducing the tangling phenomenon during feeding. During the feeding process, the joining unit beside the textile thread can be used to press the textile thread towards the center line of the dividing disc, thereby joining two or more textile threads. Specifically, the joining drive is activated, causing the joining block to move closer to the dividing disc. The center line of the yarn-binding block and the limiting groove on the yarn-binding block clamp the yarn to be combined and press it against the center line of the yarn-separating disc. Since the distance between the multiple yarn-binding blocks and the yarn-separating disc is different, the multiple yarn-binding blocks do not interfere with each other when moving closer to the center of the yarn-separating disc. In this way, the yarn to be combined is pressed to the center line of the yarn-separating disc to achieve yarn combination. At this time, the yarn-separated yarn can be directly guided and positioned. Therefore, the present invention can directly, flexibly and stably realize the feeding of single or multiple yarns according to the needs of use. When feeding multiple yarns, they can be directly combined and replaced. When used on a textile machine, it is not necessary to frequently change the yarn spool, which greatly improves the textile efficiency.

[0007] As a further improvement to the above technical solution, the present invention also includes a fixing member, which is spaced apart on the side of the splitter disc away from the merging unit. A tensioning unit is provided on the fixing member, the tensioning unit including a fixing arm, a tensioning arm, a spring, and a guide wheel. One end of the tensioning arm is rotatably connected to the fixing member, and the guide wheel is rotatably connected to the other end of the tensioning arm. The fixing arm is connected to the fixing member and is located on the side of the tensioning arm away from the center line of the splitter disc. The spring is connected between the fixing arm and the tensioning arm, and the spring has a tendency to swing the tensioning arm towards the center of the splitter disc. The number of tensioning units is equal to the number of merging units. Before the textile thread is positioned in the dividing groove on the dividing plate, it passes through a fixing component. The tensioning unit on the fixing component provides tension to the textile thread. Specifically, the guide wheel on the tensioning arm abuts against the textile thread and presses it against the center line of the dividing plate. The spring connecting the fixing arm and the tensioning arm provides stable pressure to the tensioning arm. This ensures that the textile thread drawn from the dividing groove maintains tension, which is beneficial for the combining block to press the textile thread to the center position of the dividing plate when the threads are combined. In addition, when the combining block presses the textile thread to the center of the dividing plate, the textile thread is further tightened. At this time, the pressure of the textile thread between the dividing plate and the fixing component on the tensioning arm increases, and the spring is further compressed. This maintains the tension of the textile thread during feeding and ensures that the textile thread is not easily broken when it is combined, thus improving the stability of the textile thread feeding and positioning.

[0008] As a further improvement to the above technical solution, the fixing member has through holes at the positions corresponding to all the thread guide grooves. Two thread guide rollers are rotatably connected to each through hole in a vertical direction, and the outer peripheral walls of the two thread guide rollers are provided with thread guide grooves. Multiple textile threads pass through the multiple through holes on the fixing member. When passing through the through holes, the textile threads further pass through the thread guide grooves of the upper and lower thread guide rollers. The thread guide grooves limit the movement of the textile threads, and the thread guide rollers can rotate under the drive of the textile threads to reduce friction between the textile threads and the thread guide rollers, thereby reducing wear on the textile threads.

[0009] As a further improvement to the above technical solution, a twister is also provided on the fixing member opposite each of the through holes. The twister includes a fixing frame, a first drive motor, a rotating ring, a second drive motor, and a transition cylinder. The fixing frame is connected to the side of the fixing member opposite the splitter disc. The rotating ring and the transition cylinder are both rotatably connected to the fixing frame. The rotation axes of the rotating ring and the transition cylinder extend in the left-right direction. The transition cylinder is located on the side of the rotating ring closer to the splitter disc. The first drive motor drives and connects to the rotating ring. A positioning ring is connected to the inner side of the rotating ring. The second drive motor drives and connects to the transition cylinder. The outer diameter of the transition cylinder gradually decreases in the direction close to the rotating ring. After passing through the guide groove between the two guide rollers, the textile thread passes through the positioning ring on the rotating ring. The second drive motor drives the transition drum to rotate, causing the textile thread to wind around the outside of the transition drum. When twisting the textile thread is not required, the first drive motor does not work. The textile thread is released from the end of the transition drum near the rotating ring, passes through the center of the transition drum, and is led outward. When the textile thread needs to be combined, the first drive motor works, driving the positioning ring to rotate to twist the textile thread. Similarly, the textile thread is released from the end of the transition drum near the rotating ring and then led outward from the center of the transition drum. At this time, multiple textile threads intertwine when pressed to the center of the separating disc, increasing the tightness of the textile thread when combined. In this way, different textile threads can be selectively twisted according to the needs of use, further improving the overall practicality.

[0010] As a further improvement to the above technical solution, an air pump is connected to the fixing component, and an air suction channel is provided inside the fixing component. Multiple negative pressure suction holes, interconnected with the air suction channel, are provided on the side wall of the through hole. The air pump is connected to the air suction channel via a pipeline. When the textile thread passes through the through hole, the air pump, through the pipeline and air suction channel, generates a negative pressure airflow at the negative pressure suction holes. This can adsorb lint on the textile thread, improving the working environment of the textile thread during subsequent conveying operations. Furthermore, the presence of multiple negative pressure suction holes allows for airflow in different directions at the through hole, resulting in efficient vibration of the textile thread. This high-frequency vibration shakes off dust, improving the cleaning effect on the textile thread.

[0011] As a further improvement to the above technical solution, a tensioning drive is connected to the fixing member, and the tensioning drive drives a slider. The tensioning drive can move the slider along the direction of approaching or moving away from the center line of the dividing disc. The guide wheel is rotatably connected to the slider, and the fixing arm is connected to the slider. When increasing the tension of the textile thread located between the dividing disc and the fixing member, the tension provided by the tensioning unit can be further adjusted. Specifically, the tensioning drive can drive the tensioning unit to move along the direction of approaching or moving away from the center line of the dividing disc through the slider. When the tensioning unit is close to the center line of the dividing disc, the tension force provided by the tensioning unit increases; when the tensioning unit is far from the center line of the dividing disc, the tension force provided by the tensioning unit decreases. In this way, the tension force on the textile thread can be flexibly adjusted in practical applications, so that the textile thread can be kept taut without being easily broken.

[0012] As a further improvement to the above technical solution, the present invention also includes a base plate and a sliding plate. A translational drive component is connected to the base plate, and the translational drive component drives the sliding plate to slide in a front-to-back direction. The yarn distributor and the fixing component are both connected to the sliding plate. In use, the translational drive component can drive the entire textile yarn positioning device to move back and forth through the sliding plate, thereby adjusting the front and back position of the textile yarn to meet different usage requirements.

[0013] As a further improvement to the above technical solution, a frame is also included, on which a lifting drive component is connected. The base plate is slidably connected to the frame in the vertical direction, and the lifting drive component drives the base plate. In use, the lifting drive component can move the entire textile thread positioning device up and down through the base plate, thereby adjusting the height of the textile thread lead-out to meet different usage requirements.

[0014] As a further improvement to the above technical solution, the yarn-combining block is shaped like a roller, and the limiting groove is formed on the outer peripheral wall of the yarn-combining block and extends along the circumference of the yarn-combining block. The yarn-combining block is a rotatable roller structure. When pressed against the textile thread, the textile thread enters the limiting groove and is limited. When the textile thread is being fed, it can drive the yarn-combining block to rotate, thereby reducing friction between the textile thread and the yarn-combining block.

[0015] As a further improvement to the above technical solution, the distribution reel is made of metal and is connected to a grounding wire. In use, the grounding wire can be connected to a grounded connection. When the textile thread passes through the distribution reel, the static electricity generated during the feeding process can be conducted from the distribution reel to the grounding wire, thereby eliminating the static electricity generated by the textile thread.

Detailed Implementation

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A textile thread positioning device includes: a thread separating disc 1, the center line of which extends in a left-right direction, and a plurality of thread separating grooves 11 arranged around the outer peripheral wall of the thread separating disc 1; and a thread combining unit, which includes a mounting frame 21, a thread combining drive 22, and a thread combining block 23. The mounting frame 21 is connected to the outer peripheral wall of the thread separating disc 1, and the thread combining drive 22 is connected to the mounting frame 21. The thread combining drive 22 drives the thread combining block 23, and a limiting groove is provided on the thread combining block 23 at a position opposite to the center line of the thread separating disc 1. The thread combining drive 22 can drive the thread combining block 23 to move radially along the thread separating disc 1, so that the limiting groove is close to or away from the center line of the thread separating disc 1. There are multiple thread combining units, and the distance between the multiple thread combining blocks 23 and the thread separating disc 1 is different for each of them. The limiting grooves on the multiple thread combining blocks 23 are one-to-one opposite to the multiple thread separating grooves 11 in a left-right direction.

[0025] In this textile thread positioning device, when textile threads need to be guided and positioned, multiple textile threads are guided through the dividing plate 1. At this time, the multiple textile threads are arranged one-to-one and pass through multiple dividing grooves 11 on the outer peripheral wall of the dividing plate 1. The multiple dividing grooves 11 separate and position the different textile threads, effectively reducing the tangling phenomenon of textile threads during guidance. During the guidance of textile threads, the joining unit on the side of the textile thread can be used to press the textile thread towards the center line of the denominator plate according to the needs of use, thereby joining two or more textile threads. Specifically, the joining drive 22 is activated, and the joining block 23 is moved closer to the dividing plate 1. The center line of the spinning block 23 is used to clamp and press the textile thread to be fused onto the center line of the spinning reel 1. Since the distances between the multiple spinning blocks 23 and the spinning reel 1 are different, the multiple spinning blocks 23 do not interfere with each other when they move closer to the center of the spinning reel 1. In this way, the textile thread to be fused is pressed to the center line of the spinning reel 1 to achieve fusion. At this time, the fused textile thread can be directly guided and positioned. Therefore, the present invention can directly, flexibly and stably realize the feeding of single or multiple threads according to the needs of use. When feeding multiple threads, they can be directly combined and replaced. When used on a textile machine, it is not necessary to frequently change the spool, which greatly improves the textile efficiency.

[0026] In practical applications, the textile thread led out from the splitter groove 11 can be located in the limiting groove of the combining block 23. The limiting groove further limits the position of the textile thread, thereby improving the feeding stability of the textile thread. The external textile machine has a device that provides tension to each textile thread. In order to further facilitate the maintenance of tension on the textile thread after cutting, in this embodiment, each combining unit also includes a clamping drive 81 and a clamping block 82. The clamping drive 81 is connected to the mounting frame 21. The clamping drive 81 is located on the side of the combining drive 22 away from the splitter disc 1. The clamping drive 81 drives two clamping blocks 82. The clamping drive 81 can drive the two clamping blocks 82 to move closer or further away from each other. The clamping drive 81 can be a pneumatic or electric clamping finger. When the textile thread is being led out, the two clamping blocks 82 are in a state of being far apart from each other. After the textile thread passes through the limiting groove, it passes between the two clamping blocks 82 and is then led out. Before the external equipment needs to cut the textile thread, the two clamping blocks 82 move closer to each other and clamp the textile thread under the drive of the clamping drive. At this time, the tension of the textile thread after it is led out from the splitter 1 is not affected, and the thread combining operation can be performed normally.

[0027] To ensure sufficient tension on the fixing member 3 passing through the splitter disc 1, the present invention further includes a fixing member 3, which is spaced apart on the side of the splitter disc 1 away from the merging unit. The fixing member 3 is equipped with a tensioning unit, which includes a fixing arm 31, a tensioning arm 32, a spring 33, and a guide wheel 34. One end of the tensioning arm 32 is rotatably connected to the fixing member 3, and the guide wheel 34 is rotatably connected to the other end of the tensioning arm 32. The fixing arm 31 is connected to the fixing member 3 and is located on the side of the tensioning arm 32 away from the center line of the splitter disc 1. The spring 33 is connected between the fixing arm 31 and the tensioning arm 32, and the spring 33 has a tendency to cause the tensioning arm 32 to swing towards the center of the splitter disc 1. The number of tensioning units is equal to the number of merging units. Before the textile thread is positioned on the dividing groove 11 of the dividing plate 1, it passes through the fixing member 3. The tensioning unit on the fixing member 3 can provide tension to the textile thread. Specifically, the guide wheel 34 on the tensioning arm 32 abuts against the textile thread and presses the textile thread toward the center line of the dividing plate 1. The spring 33 connected between the fixing arm 31 and the tensioning arm 32 can provide stable pressure to the tensioning arm 32. This can ensure that the textile thread drawn from the dividing groove 11 is kept in a taut state, which is beneficial for the joining block 23 to press the textile thread to the center position of the dividing plate 1 when the thread is joined. In addition, when the joining block 23 presses the textile thread to the center of the dividing plate 1, the textile thread is further tightened. At this time, the pressure of the textile thread between the dividing plate 1 and the fixing member 3 on the tensioning arm 32 increases, and the spring 33 is further compressed. This can maintain the tension of the textile thread during feeding and ensure that the textile thread is not easily broken when joined, thus improving the stability of the textile thread feeding and positioning.

[0028] The fixing member 3 can be a simple frame structure. The tensioning unit is mounted on the fixing member 3 to provide tension to the textile thread before it passes through the yarn guide plate 1. To further improve the stability of the textile thread feeding, the fixing member 3 can be a flat plate structure. In this embodiment, the fixing member 3 has through holes at positions opposite to all the yarn guide grooves 11. Each through hole contains two yarn guide rollers that rotate vertically. The outer peripheral walls of the two yarn guide rollers are provided with yarn guide grooves. Multiple textile threads pass through the multiple through holes on the fixing member 3. When passing through the through holes, the textile threads further pass through the yarn guide grooves of the upper and lower yarn guide rollers. The yarn guide grooves limit the movement of the textile threads, and the yarn guide rollers can rotate under the drive of the textile threads to reduce friction between the textile threads and the yarn guide rollers, thereby reducing wear on the textile threads.

[0029] When it is not necessary to join the yarn together or when it is not necessary to tightly connect the yarn during joining, it is not necessary to twist the yarn. However, in order to improve the joining effect of the yarn, such as Figure 5As shown, in this embodiment, a twister 4 is also provided on the fixing member 3 opposite to each of the through holes. The twister 4 includes a fixing frame 41, a first drive motor 42, a rotating ring 43, a second drive motor 44, and a transition cylinder 45. The fixing frame 41 is connected to the side of the fixing member 3 opposite to the dividing plate 1. The rotating ring 43 and the transition cylinder 45 are both rotatably connected to the fixing frame 41. The rotation axes of the rotating ring 43 and the transition cylinder 45 both extend in the left-right direction. In practical applications, the outer side of the rotating ring 43 and the outer side of the transition cylinder 45 can be connected to... It has a rotating bearing, and is rotatably connected to the fixed member 3 through the rotating bearing. The transition cylinder 45 is located on the side of the rotating ring 43 closer to the dividing plate 1. The first drive motor 42 drives and connects to the rotating ring 43. The inner side of the rotating ring 43 is connected to the positioning ring 431. The second drive motor 44 drives and connects to the transition cylinder 45. The first drive motor 42 and the second drive motor 44 can drive the rotating ring 43 and the transition cylinder 45 to rotate through belts respectively. The outer diameter of the transition cylinder 45 gradually decreases in the direction close to the rotating ring 43. After passing through the guide groove between the two guide rollers, the textile thread passes through the positioning ring 431 on the rotating ring 43. The second drive motor 44 drives the transition drum 45 to rotate, causing the textile thread to wind around the outside of the transition drum 45. When it is not necessary to twist the textile thread, the first drive motor 42 does not work. The textile thread is released from the end of the transition drum 45 near the rotating ring 43, passes through the center of the transition drum 45, and is led outward. When it is necessary to combine the textile thread, the first drive motor 42 works, driving the positioning ring 431 to rotate to twist the textile thread. Similarly, the textile thread is released from the end of the transition drum 45 near the rotating ring 43 and is led outward from the center of the transition drum 45. At this time, multiple textile threads are intertwined when pressed to the center of the separating disc 1, which increases the tightness of the textile thread when combining. In this way, different textile threads can be selectively twisted according to the needs of use, further improving the overall practicality.

[0030] In practical applications, the textile spool can be directly unwound vertically on the ground, or it can be installed on an external positioning rod. The positioning rod passes through the center of the spool for positioning, and the textile thread is directly pulled out of the spool and guided to the through hole. At this time, some textile threads have a lot of fluff, which is easy to shed during subsequent feeding. In order to improve the working environment, in this embodiment, the fixing member 3 is connected to an air pump, the fixing member 3 is provided with an air suction channel, and the side wall of the through hole is provided with multiple negative pressure suction holes that communicate with the air suction channel. The air pump is connected to the air suction channel through a pipeline. The suction airflow channel within the fixture 3 includes a main flow channel and a branch flow channel. A branch flow channel is provided around each through hole within the fixture 3. Multiple negative pressure suction holes are arranged around the inner sidewall of the through hole. These multiple negative pressure suction holes are directly connected to the branch flow channels. One end of the main flow channel is connected to the suction pump, while the other end extends around the center of the distribution disc 1 within the fixture 3 and connects to all the branch flow channels. When the textile thread passes through the through hole, the suction pump generates negative pressure airflow at the negative pressure suction holes through the pipeline and suction airflow channel. This can adsorb lint on the textile thread, which helps to improve the working environment of the textile thread during subsequent conveying operations. In addition, there are multiple negative pressure suction holes, which can generate airflow in different directions at the through hole, thereby causing the textile thread to vibrate efficiently. The textile thread shakes off dust during high-frequency vibration, improving the cleaning effect on the textile thread.

[0031] In each of the above tensioning units, the fixed arm 31 and the tensioning arm 32 can be directly connected to the fixing member 3. At this time, the position of the entire tensioning unit on the fixing member 3 is relatively fixed. In order to achieve the effect of automatically adjusting the tension, in this embodiment, a tensioning drive member 35 is connected to the fixing member 3. The tensioning drive member 35 drives the slider 36 to move along the direction of approaching or away from the center line of the dividing plate 1. The guide wheel 34 is rotatably connected to the slider 36, and the fixed arm 31 is connected to the slider 36. When increasing the tension of the textile thread located between the splitter disc 1 and the fixing member 3, the tension provided by the tensioning unit can be further adjusted. Specifically, the tensioning drive member 35 can drive the tensioning unit to move along the direction of approaching or moving away from the center line of the splitter disc 1 via the slider 36. When the tensioning unit is close to the center line of the splitter disc 1, the tension force provided by the tensioning unit increases, and when the tensioning unit is far from the center line of the splitter disc 1, the tension force provided by the tensioning unit decreases. In this way, the tension of the textile thread can be flexibly adjusted in practical applications, so that the textile thread can be kept taut and is not easily broken.

[0032] When applied to textile machines, the position of the textile thread lead-out needs to be adjusted, especially when textile threads at different positions on the yarn distributor 1 need to be guided. Therefore, this invention also includes a base plate 51 and a sliding plate 52. A translation drive is connected to the base plate 51, which drives the sliding plate 52. The translation drive can move the sliding plate 52 in a front-back direction. The yarn distributor 1 and the fixing member 3 are both connected to the sliding plate 52. In use, the translation drive can move the entire textile thread positioning device back and forth via the sliding plate 52, thereby adjusting the front-back position of the textile thread lead-out to meet different usage requirements.

[0033] Furthermore, the present invention also includes a frame 6, on which a lifting drive component is connected. The base plate 51 is slidably connected to the frame 6 in the vertical direction, and the lifting drive component drives the base plate 51. In use, the lifting drive component can drive the entire textile thread positioning device to move up and down through the base plate 51, thereby adjusting the height of the textile thread lead-out to meet different usage requirements.

[0034] This textile thread positioning device can also be directly applied to a winding machine. In this case, the fed textile thread needs to be moved back and forth at a high frequency to achieve winding on the drum inside the winding machine. Therefore, in this embodiment, a linear drive is connected to the slide plate 52. The linear drive is located on the side of the splitter 1 away from the combining unit. Multiple pressing units are connected to the linear drive. The linear drive can drive the multiple pressing units to move back and forth. The pressing unit includes a base 71, a pressing drive 72, and a pressing block 73. The base 71 is connected to the linear drive, and the pressing drive 72 is connected to the base 71. The pressing drive 72 drives the pressing block 73. The pressing drive 72 can drive the pressing block 73 to move up and down. The bottom side of the pressing block 73 is provided with a pressing groove extending in the left and right direction. Each pressing unit can press the textile thread in its vertical direction into the pressing groove. Then, driven by the linear drive, the textile thread moves back and forth. Specifically, the pressing block 73 is located above the dividing plate 1. When the textile thread needs to be pressed into the pressing groove, the pressing drive 72 drives the pressing block 73 to move down onto the base 71. The pressing block 73 presses down the textile thread led out of the limiting groove and positions it in the pressing groove. In this way, the textile thread can be driven by the linear drive to move back and forth at a high frequency, making it more flexible and convenient to use.

[0035] In practical applications, the wire-combining drive 22, tensioning drive 35, translation drive, lifting drive, linear drive, and pressing drive 72 are all used to provide driving force in the linear direction. They have various structural forms, such as pneumatic push rods, electric push rods, or hydraulic push rods.

[0036] The yarn-combining block 23 can be a block structure. However, to reduce friction when the yarn passes through the limiting groove, in this embodiment, the yarn-combining block 23 is shaped like a roller. In this case, the yarn-combining block 23 can rotate on the yarn-combining drive member 22. The limiting groove is formed on the outer peripheral wall of the yarn-combining block 23 and extends circumferentially along the yarn-combining block 23. The yarn-combining block 23 is a rotatable roller structure. When pressed against the yarn, the yarn enters the limiting groove and is limited. During the feeding process, the yarn can drive the yarn-combining block 23 to rotate, thereby reducing friction between the yarn-combining block 23 and the yarn-combining block 23.

[0037] In some embodiments, the distributor 1 is made of metal and is connected to a grounding wire. In use, the grounding wire can be connected to a grounded connection. When the textile thread passes through the distributor 1, the static electricity generated during the feeding process can be conducted from the distributor 1 to the grounding wire, thereby eliminating the static electricity generated by the textile thread.

[0038] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
