Description

[0001] This application is based on a divisional application with application number: 2022110752292; application date: September 4, 2022; and name: A main shuttle adjustment mechanism in a yarn feeding device. Technical Field

[0002] The invention relates to a main-mouth yarn feeding device, in particular to a main shuttle regulating mechanism in the yarn feeding device. Background Art

[0003] In the current market, there are many types of sock machines with different structures, and the yarn feeding structures used by each sock machine are also unique. Imported sock machines mostly use high-precision processing and positioning to control the coordination between the main yarn feeding device and the knitting needles. Some shuttles are equipped with a front and rear adjustment function to adjust the front and rear position of the shuttle. Although the control accuracy is high, it is impossible to adjust the position of each shuttle for the processing requirements of some special socks, resulting in the inability to produce some special socks, and the adaptability is not high. Domestic sock machines basically use a lever-type adjustment control method, which can adjust the front and rear position of each shuttle separately, but some are often relatively complex in structure, and the shuttle is prone to offset during operation, and the yarn feeding is unstable, which easily leads to an increase in the defective rate.

[0004] In view of the above-mentioned defects in the prior art, those skilled in the art have made certain improvements. For example, a main yarn feeding device based on independent front and rear adjustment of the main shuttle is disclosed in a Chinese patent (publication number CN110644126A), which includes a main shuttle frame on which more than two main shuttles are mounted, and the main shuttle has at least one adjusting device with front and rear and up and down position; the adjusting device includes a front and rear adjusting device and an up and down adjusting device.

[0005] The above patent realizes the independent front and rear adjustment action of the main shuttle, but its structure is complex, and its adjustment accuracy and stability are poor. In particular, the vibration caused by the high-speed operation of the sock machine will directly affect the stability of the main shuttle. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a main shuttle adjustment mechanism that facilitates independent front and rear adjustment and positioning of the main shuttle.

[0007] In order to achieve the purpose of innovation, the present invention can be achieved through the following technical solutions: a main shuttle adjustment mechanism in a yarn feeding device, including a main shuttle frame, on which at least two main shuttles are arranged, the adjustment mechanism also includes an adjustment bracket connected to the main shuttle, a guide unit for guiding the forward and backward movement of the adjustment bracket is provided between the adjustment bracket and the main shuttle frame, and the main shuttle frame is also provided with an adjustment unit that can drive the adjustment bracket to move forward and backward along the main shuttle frame and lock it.

[0008] The main shuttle of the adjusting mechanism is mainly used to control the yarn feeding position. The main shuttle is arranged on the main shuttle frame. The adjusting bracket is used to control the front and rear position of the main shuttle. The guide unit arranged between the adjusting bracket and the main shuttle frame limits the adjusting bracket to move back and forth only in a horizontal position. The adjusting unit is used to control and lock the front and rear movement of the adjusting bracket, thereby realizing independent front and rear adjustment and locking of the single main shuttle.

[0009] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, the guide unit includes a guide post arranged on the main shuttle frame and a guide groove arranged on the adjustment bracket, the guide post is embedded in the guide groove and the guide groove can slide along the guide post.

[0010] The guide unit achieves the guiding effect by adjusting the guide groove of the bracket to be stuck in the guide column on the main shuttle frame. The size of the guide groove matches the guide column to ensure that the guide column can slide but will not cause excessive up and down movement to produce a large deviation, that is, the adjustment bracket is limited to horizontal forward and backward movement.

[0011] In the main shuttle adjustment mechanism in the yarn feeding device, there are two guide posts and two guide grooves, and the guide grooves are provided with openings and the openings of the two guide grooves face opposite directions.

[0012] Both the guide column and the guide groove are provided at the front and rear sides, making the structure more stable. The guide grooves are respectively opened at the front and rear sides and are open. This structure is easy to install, and when sliding to the front end, the innermost side of the guide groove at the rear side presses against the guide column to limit it from sliding forward. The same is true when sliding to the rear end, ensuring that the adjustment bracket always slides horizontally.

[0013] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, the guide unit includes a guide groove arranged on the main shuttle frame and a guide post arranged on the adjustment bracket, and the guide post is embedded in the guide groove and can slide along the guide groove.

[0014] As another solution, in the main shuttle adjustment mechanism of the above-mentioned yarn feeding device, the guide unit can also be a guide groove set on the main shuttle frame and a guide column set on the adjustment frame, and the guide column slides in the guide groove with matching size and shape to achieve guiding control of the adjustment bracket, limiting it to move forward and backward only in the horizontal direction.

[0015] In the above-mentioned yarn feeding device, the adjusting unit includes an adjusting plate located on the adjusting bracket, a positioning plate arranged on the main shuttle frame and an adjusting bolt arranged on the positioning plate. The adjusting bolt is arranged on the positioning plate and rotating the adjusting bolt can make the adjusting bolt move up and down along the positioning plate. The adjusting plate is provided with an inclined guide surface, and the end of the adjusting bolt abuts against the guide surface.

[0016] The adjusting bolt is passed through the positioning plate and can move up and down. The adjusting bracket is provided with an inclined guide surface. The up and down movement of the adjusting bolt is utilized to make the end face of the adjusting bolt press against the guide surface of the adjusting plate, thereby converting the up and down movement of the adjusting bolt into the movement of the adjusting bracket in the front and rear directions. The adjusting plate and the adjusting bracket can be arranged as an integrated type or as a separate type.

[0017] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, there are two adjustment plates, including an adjustment front plate and an adjustment rear plate, and there are also two adjustment bolts, including a front adjustment bolt and a rear adjustment bolt. The front adjustment bolt abuts against the adjustment front plate, and the rear adjustment bolt abuts against the adjustment rear plate.

[0018] There are two adjustment plates. By pressing down the front adjusting bolt to adjust the front plate and lifting the rear adjusting bolt at the same time, the adjustment bracket can slide forward. By pressing down the rear adjusting bolt to adjust the rear plate and lifting the front adjusting bolt at the same time, the adjustment bracket can slide backward. After adjusting the position, the lifted adjusting bolt is screwed down until it rests against the adjustment plate to lock the front and rear of the adjustment bracket, and the structure is stable.

[0019] In the main shuttle adjusting mechanism in the yarn feeding device described above, the end faces of the front adjusting bolt and the rear adjusting bolt are both provided with cut surfaces matching the guide surface of the adjusting plate.

[0020] The guide surface is an inclined surface, which is 35 degrees to the vertical direction. The cross section of the adjusting bolt fits the guide surface, which is conducive to better converting the downward force of the adjusting bolt into the force for the adjustment bracket to slide forward and backward, and the end face of the adjusting bolt is not easy to wear too quickly.

[0021] In the main shuttle adjustment mechanism in the yarn feeding device, the guide surfaces of two adjacent adjustment front plates are staggered in the left-right direction, and the guide surfaces of two adjacent adjustment rear plates are staggered in the left-right direction.

[0022] Since the adjustment mechanism itself is relatively precise and small in size, the purpose of staggering is to save space. At the same time, the adjustment bolts that cooperate with the adjustment plate are also staggered, which makes it easier to use bolts of sufficient size and facilitate operation.

[0023] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, the adjustment unit includes a swing module arranged on the main shuttle frame, and the adjustment bracket is provided with a connecting part that is buckled with the swing module. When the swing module swings, the adjustment bracket can be driven to move forward and backward along the main shuttle frame through the connecting part.

[0024] As another solution for controlling the forward and backward movement of the adjusting bracket, the forward and backward movement and locking of the adjusting bracket are achieved through a swing module, and the swing part swings to move the connecting part buckled therewith to achieve the forward and backward movement of the adjusting bracket.

[0025] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, the swing module includes a swing frame hinged on the main shuttle frame, the swing frame is provided with a raised swing part, the connecting part is a connecting groove arranged on the adjustment bracket, and the swing part is embedded in the connecting groove.

[0026] The swing frame is hinged on the main shuttle frame and can swing with the hinge shaft as the axis. That is, when swinging, the swing part at its lower end has a circumferential motion roughly in the front-to-back direction. The end of the swing part is circular and the connecting groove is an open ring. Therefore, when the swing part is embedded in the open ring-shaped connecting groove, the circumferential swing of the swing frame can be converted into the front-to-back motion of the adjusting bracket.

[0027] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, a parallel scheme: the swing module includes a swing frame hinged on the main shuttle frame, the connecting part is a connecting head arranged on the adjustment bracket, and the swing frame is provided with a swing part that can be sleeved on the connecting head.

[0028] As another solution, the swinging part is in the shape of an open ring, and the adjusting bracket is provided with a protruding connecting head, the connecting head is circular, and the swinging part is sleeved on the connecting head, so that the swinging part can drive the connecting head to move forward and backward when swinging, thereby driving the adjusting bracket to move forward and backward.

[0029] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, the swing module also includes a positioning plate arranged on the main shuttle frame, and the positioning plate is provided with adjustment bolts. The adjustment bolts are in two groups and are respectively arranged on both sides of the hinge shaft of the swing frame.

[0030] The positioning plate is located on the main shuttle frame above the adjustment bracket. The adjusting bolt is passed through the positioning plate and can be moved up and down by rotating. It is arranged on both sides of the hinge shaft. The adjusting bolts are used to control the forward and backward movement of the swing frame respectively. When the adjusting bolt on the front side is screwed down and the adjusting bolt on the rear side is screwed up at the same time, the effect of moving the adjustment bracket backward can be achieved. When the adjusting bolt on the rear side is screwed down and the adjusting bolt on the front side is screwed up at the same time, the effect of moving the adjustment bracket forward can be achieved. When the adjustment position is in place, the upward adjusting bolt is screwed down until the end is against the swing frame to complete the locking.

[0031] In the main shuttle adjusting mechanism in the above-mentioned yarn feeding device, two adjacent adjusting bolts are staggered in the front-rear direction.

[0032] In order to save space and facilitate operation, two adjacent adjusting bolts are staggered in the front-to-back direction.

[0033] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, the adjustment bracket is provided with a buckling part, the main shuttle is provided with a buckling groove, the buckling part is embedded in the buckling groove, and the main shuttle can swing with the buckling part as the axis.

[0034] A buckling portion protrudes from the adjusting bracket, and the buckling portion is embedded in the buckling groove of the main shuttle, which transmits the movement state of the adjusting bracket to the main shuttle, so that the front and rear position control and locking of the main shuttle can be realized, and the connection between the main shuttle and the adjusting bracket can rotate relatively, and the main shuttle can be controlled up and down in combination with other control components.

[0035] In the main shuttle adjustment mechanism in the above-mentioned yarn feeding device, the main shuttle is provided with a buckling part, the adjustment bracket is provided with a buckling groove, the buckling part is embedded in the buckling groove, and the main shuttle can swing with the buckling part as the axis.

[0036] As another solution, a buckling part is provided on the main shuttle, and the buckling part is embedded in the connecting part of the adjusting bracket, so that the movement state of the adjusting bracket is transmitted to the main shuttle, that is, the front and rear position control and locking of the main shuttle can be realized, and the connection between the main shuttle and the adjusting bracket can be relatively rotated, and the main shuttle can be controlled up and down in combination with other control components.

[0037] In the main shuttle adjustment mechanism in the yarn feeding device described above, the number of the main shuttles is 2-6, and the number of the adjustment brackets, guide units and adjustment units matched therewith is also 2-6.

[0038] The number of main shuttles is 2-6, which can be set according to actual needs. The number of matching adjustment brackets, guide units and adjustment units matches the number of main shuttles to achieve individual control of each main shuttle.

[0039] Compared with the existing technology,

[0040] 1. The adjusting mechanism is used to control the front and rear position of the main shuttle through the adjusting bracket, rather than directly acting on the main shuttle, which makes it convenient for the main shuttle to swing when in use. The guide unit arranged between the adjusting bracket and the main shuttle frame restricts the adjusting bracket to move back and forth only in a horizontal position. The adjusting unit is used to control and lock the front and rear movement of the adjusting bracket, thereby achieving the front and rear control effect of the main shuttle.

[0041] 2. The guide unit achieves the guiding effect by adjusting the guide groove of the bracket to be stuck in the guide column on the main shuttle frame. The size of the guide groove matches the guide column to ensure that the guide column can slide, but will not cause excessive up and down movement to produce a large deviation, that is, the adjustment bracket is limited to horizontal forward and backward movement.

[0042] 3. Both the guide column and the guide groove are provided at the front and rear sides, making the structure more stable. The guide grooves are respectively provided at the front and rear sides, and are open-type. This structure is convenient for installation, and when sliding to the front end, the innermost side of the guide groove at the rear side presses against the guide column to limit the forward movement, and the same is true when sliding to the rear end, ensuring that the adjustment bracket always slides horizontally.

[0043] 4. There are two adjustment plates. The front plate is adjusted by pressing down the front adjusting bolt while the rear adjusting bolt is lifted up to achieve the forward sliding of the adjustment bracket. The rear plate is adjusted by pressing down the rear adjusting bolt while the front adjusting bolt is lifted up to achieve the backward sliding of the adjustment bracket. After adjusting the position, the lifted adjusting bolt is screwed down until it rests against the adjustment plate to lock the front and rear of the adjustment bracket, and the structure is stable.

[0044] 5. A buckling part protrudes from the adjusting bracket, and the buckling part is embedded in the buckling groove of the main shuttle, which transmits the movement state of the adjusting bracket to the main shuttle, that is, the front and rear position control and locking of the main shuttle can be realized, and the connection between the main shuttle and the adjusting bracket can rotate relatively, and the main shuttle can be controlled up and down in combination with other control components.

[0045] 6. The adjusting bolts and adjusting plates are staggered to save space and facilitate operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0054] In this embodiment, the horizontal direction of the plane where the main shuttle is located is assumed to be the front-to-back direction, and the vertical direction is assumed to be the left-to-right direction.

[0055] Example 1

[0056] like Figure 1-4 As shown, the main shuttle adjustment mechanism in the yarn feeding device includes a main shuttle frame 5, on which at least two main shuttles 1 are arranged. The adjustment mechanism also includes an adjustment bracket 2 connected to the main shuttle 1, and a guide unit 3 for guiding the forward and backward movement of the adjustment bracket 2 is arranged between the adjustment bracket 2 and the main shuttle frame 5. The main shuttle frame 5 is also provided with an adjustment unit 4 which can drive the adjustment bracket 2 to move forward and backward along the main shuttle frame 5 and lock it.

[0057] Specifically, the main shuttle 1 of the adjusting mechanism is mainly used to control the yarn feeding position. The main shuttle 1 is arranged on the main shuttle frame 5. The adjusting bracket 2 is used to control the front and rear position of the main shuttle 1. The guide unit 3 arranged between the adjusting bracket 2 and the main shuttle frame 5 limits the adjusting bracket 2 to move back and forth only in a horizontal position. The adjusting unit 4 is used to control and lock the front and rear movement of the adjusting bracket 2, thereby realizing the front and rear control effect of the main shuttle 1.

[0058] like Figure 4 As shown, preferably, the guide unit 3 includes a guide post 31 provided on the main shuttle frame 5 and a guide groove 32 provided on the adjustment bracket 2, the guide post 31 is embedded in the guide groove 32 and the guide groove 32 can slide along the guide post 31. There are two guide posts 31 and two guide grooves 32, and the guide grooves 32 are provided with openings and the openings of the two guide grooves 32 face opposite directions.

[0059] The guide unit 3 achieves a guiding effect by clamping the guide groove 32 of the adjustment bracket 2 in the guide column 31 on the main shuttle frame 5. The size of the guide groove 32 matches the guide column 31 to ensure that the guide column 31 can slide, but will not cause excessive up and down movement to produce a large deviation, that is, the adjustment bracket 2 is limited to horizontal forward and backward movement. Both the guide column 31 and the guide groove 32 are provided with two front and rear, making the structure more stable. The guide groove 32 is respectively opened on the front and rear sides and is an open type. This structure is easy to install, and when sliding to the front end, the innermost side of the guide groove 32 on the rear side presses against the guide column 31 to limit it from sliding forward. The same is true when sliding to the rear end, ensuring that the adjustment bracket 2 always slides horizontally.

[0060] like Figure 3 and 4As shown, preferably, the adjustment unit 4 includes an adjustment plate 41 located on the adjustment bracket 2, a positioning plate 51 arranged on the main shuttle frame 5 and an adjustment bolt 42 arranged on the positioning plate 51, the adjustment bolt 42 is arranged on the positioning plate 51 and the adjustment bolt 42 can be rotated to make the adjustment bolt 42 move up and down along the positioning plate 51, an inclined guide surface 413 is provided on the adjustment plate 41, and the end of the adjustment bolt 42 abuts on the guide surface 413, and the adjustment plate 41 is divided into two, including an adjustment front plate 411 and an adjustment rear plate 412, and the adjustment There are also two bolts 42, including a front adjusting bolt 421 and a rear adjusting bolt 422. The front adjusting bolt 421 abuts against the adjusting front plate 411, and the rear adjusting bolt 422 abuts against the adjusting rear plate 412. The end faces of the front adjusting bolt 421 and the rear adjusting bolt 422 are both provided with a cross-section matching the guide surface 413 of the adjusting plate 41. The guide surfaces 413 of two adjacent adjusting front plates 411 are staggered in the left-right direction, and the guide surfaces 413 of two adjacent adjusting rear plates 412 are staggered in the left-right direction.

[0061] Specifically, the adjusting bolt 42 is passed through the positioning plate 51 and can move up and down. The adjusting bracket 2 is provided with an inclined guide surface 413. The up and down movement of the adjusting bolt 42 makes the end face of the adjusting bolt 42 press against the guide surface 413 of the adjusting plate 41, thereby converting the up and down movement of the adjusting bolt 42 into the front and rear movement of the adjusting bracket 2. The adjusting plate 41 and the adjusting bracket 2 can be arranged as an integrated type or a separate type. There are two adjusting plates 41. The front adjusting bolt 421 presses down the front adjusting plate 411 and lifts up the rear adjusting bolt 422 at the same time, so that the adjusting bracket 2 can slide forward. The rear adjusting bolt 422 presses down the rear adjusting plate 412 and lifts up the front adjusting bolt 421 at the same time, so that the adjusting bracket 2 can slide backward. After adjusting the position, the lifted adjusting bolt 42 is screwed down until it abuts against the adjusting plate 41 to achieve the front and rear locking of the adjusting bracket 2, and the structure is stable.

[0062] In addition, since the adjustment mechanism itself is relatively precise and small in size, the purpose of the mutual staggering is to save space. At the same time, the adjustment bolts 42 that cooperate with the adjustment plate 41 are also staggered, which makes it easier to use bolts of sufficient size and facilitates operation.

[0063] Preferably, a buckling portion 21 is provided on the adjusting bracket 2, a buckling groove 11 is provided on the main shuttle 1, the buckling portion 21 is embedded in the buckling groove 11, and the main shuttle 1 can swing around the buckling portion 21 as the axis.

[0064] In other words, the adjusting bracket 2 is provided with a buckling portion 21, which is embedded in the buckling groove 11 of the main shuttle 1, and the movement state of the adjusting bracket 2 is transmitted to the main shuttle 1, that is, the front and rear position control and locking of the main shuttle 1 can be realized, and the connection between the main shuttle 1 and the adjusting bracket 2 can be relatively rotated, and the main shuttle 1 can be controlled up and down in combination with other control components.

[0065] Preferably, the number of main shuttles 1 is 2-6, and the number of adjusting brackets 2, guide units 3 and adjusting units 4 matched therewith is also 2-6.

[0066] In other words, the number of main shuttles 1 is 2-6, which can be set according to actual needs. The number of matching adjustment brackets 2, guide units 3 and adjustment units 4 matches the number of main shuttles 1 to achieve individual control of each main shuttle 1.

[0067] The specific working principle is as follows: the position of the main shuttle 1 is set before yarn feeding, and each main shuttle 1 is controlled separately as needed. For example, when the main shuttle 1 needs to be moved forward, the rear adjusting bolt 422 is first tightened to make the rear adjusting bolt 422 leave the guide surface 413 to loosen the locked state, and then the front adjusting bolt 421 is tightened to make its end press down the inclined guide surface 413, and the guide surface 413 is "squeezed" forward to make the main shuttle 1 move forward. When the position is appropriate, the rear adjusting bolt 422 is tightened to press against the guide surface 413 to achieve the front and rear state locking effect of the main shuttle 1. If the main shuttle 1 needs to move backward, the same operation can be performed. When up and down adjustment is required, it can be achieved through the up and down adjustment mechanism provided on the main shuttle frame 5.

[0068] Example 2

[0069] The structural principle of this embodiment is basically the same as that of Embodiment 1, except that the adjustment method of the adjustment unit is as follows:

[0070] like Figure 5-6 As shown, the adjustment unit 4 includes a swing module 6 arranged on the main shuttle frame 5, and a connection part buckled with the swing module 6 is provided on the adjustment bracket 2. When the swing module 6 swings, the adjustment bracket 2 can be driven to move forward and backward along the main shuttle frame 5 through the connection part. The swing module 6 includes a swing frame 61 hinged on the main shuttle frame 5, and a protruding swing part 611 is provided on the swing frame 61. The connection part is a connecting groove 62 provided on the adjustment bracket 2, and the swing part 611 is embedded in the connecting groove 62. The swing module 6 also includes a positioning plate 51 arranged on the main shuttle frame 5, and an adjusting bolt 42 is provided on the positioning plate 51. The adjusting bolt 42 is divided into two groups and each is arranged on both sides of the hinge shaft 612 of the swing frame 61. Two adjacent adjusting bolts 42 are staggered in the front-to-back direction.

[0071] Specifically, as another solution for controlling the forward and backward movement of the adjustment bracket 2, the forward and backward movement and locking of the adjustment bracket 2 are realized by the swing module 6, and the forward and backward movement of the adjustment bracket 2 is realized by swinging the swing part 611 to toggle the connecting part buckled therewith. The swing frame 61 is hinged on the main shuttle frame 5 and can swing with the hinge shaft 612 as the axis. When swinging, the swing part 611 at its lower end has a circumferential movement roughly in the forward and backward direction. The end of the swing part 611 is circular, and the connecting groove 62 is an open ring. Therefore, when the swing part 611 is embedded in the open ring-shaped connecting groove 62, the circumferential swing of the swing frame 61 can be converted into the adjustment bracket 2. The front and rear sides of the swing frame 61 are provided with a plurality of adjusting bolts 42, each of which is provided with a plurality of adjusting bolts 42, each of which is provided with a plurality of adjusting bolts 42. The adjusting bolts 42 are provided with a plurality of adjusting bolts 42, each of which is ...

[0072] In addition, in order to save space and facilitate operation, two adjacent adjusting bolts 42 are staggered in the front-to-back direction.

[0073] The specific working principle is that when the main shuttle 1 needs to be adjusted forward and backward, when it is desired to adjust forward, first tighten the front adjusting bolt 421 so that it is no longer mortgaged on the upper part of the swing frame 61 to release the locking state, and then tighten the rear adjusting bolt 422 so that its end presses down on the upper part of the swing frame 61. Since the end pressing position is at the rear side of the hinge shaft 612, the swing frame 61 rotates, and the swing part 611 moves forward approximately, and the adjustment bracket moves forward, that is, the main shuttle 1 moves forward. When the position is appropriate, tighten the front adjusting bolt 421 so that its end abuts against the swing frame 61 to complete the locking state. When the main shuttle 1 is desired to be adjusted backward, first tighten the rear adjusting bolt 422 to release the locking state, and then tighten the front adjusting bolt 421 to realize the forward movement of the main shuttle 1. When the position is appropriate, tighten the rear adjusting bolt 422 to abut against it to complete the locking state. Then cooperate with the up and down adjustment mechanism set on the main shuttle frame 5 to realize the up and down adjustment of the main shuttle 1, and the up and down, front and back adjustment of the main shuttle 1 can be completed.

[0074] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
