A shedding device in a weaving machine comprises one or more motor groups including a plurality of motors provided in every heald frame and directing their output shafts in the forward and backward direction of the weaving machine. The motors of each motor groups are arranged in the upward and downward, rightward and leftward directions, and two or more motors operating as at least part of the motor group are arranged in the longitudinal direction of a connecting member connecting the motors with support mechanisms of the heald frames to form one or more motor rows opposing to one or more connecting members, and adjoining motors in the motor row or rows are related to non-adjoining heald frames among the heald frames corresponding to the support mechanisms.
Description
- 1. Field of the Invention
- The present invention relates to a shedding device for forming a warp shedding in a weaving machine.
- In this invention, a reciprocating direction of a heald frame is called a upward and downward direction; the moving direction of a warp by letting off of the warp, a forward and backward direction; the downstream side in a warp running direction, a front side; the upstream side in a warp running direction, a rear side; and a weaving width direction of the weaving machine, a rightward and leftward direction.
- 2. Description of Prior Art
- As one of devices for forming a warp shedding by moving a plurality of heald frames vertically is disclosed an electric shedding device in which each heald frame is supported by a support mechanism so as to move vertically and each support mechanism is driven by a drive motor provided at every heald frame (Japanese Patent Appln. PD (KOKAI) No. 10-130984).
- Each drive motor moves a corresponding heald frame vertically by having its output shaft connected with a corresponding support mechanism, through a mechanism for converting motion for converting the drive motor's rotation into a reciprocal motion and a connecting mechanism such as a long connecting member for transmitting the converted reciprocal motion to the support mechanism, and driving the support mechanism.
- The foregoing shedding device uses sixteen drive motors. The sixteen drive motors are divided into two motor groups each including eight motors arranged in the upper and lower as well as right and left sides of the weaving machine, with motor shafts, i.e., output shafts assembled to the outside of a frame of the weaving machine so as to extend in the forward and backward direction of the weaving machine.
- Among the drive motors of each motor group, four drive motors located on the lower side are arranged in the rightward and leftward direction of the weaving machine to form a lower side motor row, while four drive motors located on the upper side are arranged in the rightward and leftward direction of the weaving machine to form an upper side motor row. Both motor groups are spaced apart in the forward and backward direction of the weaving machine.
- In the foregoing conventional shedding device, the drive motors adjoining in the rightward and leftward direction of the weaving machine are made to correspond to heald frames adjoining in the forward and backward direction of the weaving machine to drive the corresponding heald frames. Also, a crank connecting rod of each mechanism for converting motion extends from the corresponding drive motor to transverse the front or the rear of an eccentric wheel of the mechanism for converting motion located next to the drive motor.
- In view of the above, in the conventional shedding device, half the sum of the thicknesses of the eccentric wheel and the crank connecting rod which transverse the front or the rear of the eccentric wheel should be one pitch or less of the array of the heald frames. Accordingly, the thicknesses of members including the eccentric wheel and the crank connecting rod must be made small, which deteriorates the durability of those members and causes a vibration.
- Also, in the conventional shedding device, in order not to make the crank connecting rods transverse the front or the rear of the eccentric wheels of adjoining drive motors, the drive motors should be arranged such that the plural crank connecting rods connected with the drive motors in the same motor row do not overlap in the forward and backward direction, that is, such that two adjoining crank connecting rods form a large angle therebetween, which requires a larger space to dispose the drive motors.
- It is an object of the present invention to arrange drive motors efficiently in a shedding device of a weaving machine comprising a drive motor at every heald frame, without lowering the strength of members constituting a mechanism for converting motion.
- In this invention, a reciprocating direction of a heald frame is called a upward and downward direction; the moving direction of a warp by letting off of the warp, a forward and backward direction; the downstream side in a warp running direction, a front side; the upstream side in a warp running direction, a rear side; and a weaving width direction of the weaving machine, a rightward and leftward direction.
- A shedding device in a weaving machine according to the present invention comprises: a support mechanism group including a plurality of support mechanisms for individually supporting heald frames so as to move vertically; a motor group including a plurality of motors provided at every heald frame with an output shaft directed in the forward and backward direction of the weaving machine; and a motion converting mechanism group including a plurality of mechanisms for converting motion each having a long connecting member for connecting the motors with the corresponding support mechanisms.
- The motors of the motor group are disposed on the upper, lower, right and left sides, two or more motors constituting at least part of the motor group form one or more motor rows arranged in the longitudinal direction of the connecting member, and the adjoining motors within the motor row are related to heald frames not adjoining within the heald frames corresponding to the support mechanism.
- By arranging the motors on the upper, lower, right and left sides, forming a rightward and leftward motor row with two or more motors, and relating the adjoining motors forming the motor row to heald frames not adjoining in the forward and backward direction within the heald frames corresponding to the support mechanisms, a distance between the heald frames relating to thus adjoining motors, in particular, a distance in the forward and backward direction is enlarged. Accordingly, a distance between the mechanisms for converting motion assembled to the output shafts of the motors and adjoining in the forward and backward direction can be enlarged.
- As a result of the above, a mutual intervention of the mechanisms for converting motion individually assembled to the output shafts of the plural motors forming the motor rows can be prevented. Also, even if those mechanisms for converting motion transverse the front or the rear of at least one mechanism for converting motion, the sum of the thicknesses of the adjoining mechanisms for converting motion, in particular, the sum of the thicknesses of the members located near the output shafts of the motors among the members constituting those adjoining mechanisms for converting motion, is not limited to the arrangement pitch of the heald frames adjoining in the forward and backward direction. Furthermore, without enlarging the space to dispose the motors, the mechanical strength of the mechanisms for converting motion can be enhanced.
- In a preferred embodiment, the shedding device is constituted to have the support mechanism group support part of the plural heald frames in the weaving machine and, furthermore, comprises a second support mechanism group including a plurality of second support mechanisms individually supporting other heald frames so as to move upward and downward; a second motor group including a plurality of second motors provided at every heald frame with the output shaft directed in the forward and backward direction of the weaving machine; and a second motion converting mechanism group including a plurality of second mechanisms for converting motion having long second connecting members for connecting the second motors with the corresponding second support mechanisms. The second motors of the second motor group are arranged on the upper, lower, right and left sides, two or more of the second motors constituting at least a part of the second motor group form one or more second motor rows are arranged in the longitudinal direction of the second connecting member, and the adjoining motors within the second motor row are related to the heald frames not adjoining within the heald frames corresponding to the second support mechanism.
- The second motor group and the motor group mentioned previously can be disposed in different positions at least in one direction selected from the forward and backward, upward and downward, and rightward and leftward directions. By doing so, many motors can be more efficiently arranged without lowering the strength of the members constituting the mechanisms for converting motion.
- The motors in the same motor row can be arranged such that the motors nearer to the end portion of the connecting member on the side opposite to the motors are related to the heald frames on one of the forward side and the backward side nearer to the side where the motor group are arranged, among the heald frame corresponding to the support mechanism. This enables to prevent a mutual intervention of the mechanisms for converting motion relating to the motors within the same motor row more surely.
- The heald frame adjacent to the heald frame related to the motors of the same row can be related to other motors not belonging to the same row among the motors of the motor groups. This enables to prevent more surely a mutual intervention of the mechanisms for converting motion related to the motors of the same motor row.
- In a preferred embodiment, the motors of the motor group are arranged in a plurality of rows respectively in the widthwise direction and upward and downward direction of the weaving machine; the heald frames supported by the support mechanisms of the support mechanism group are divided into a plurality of groups to which the heald frames of the same group are adjacent, each group including the number of heald frames corresponding to the number of the motors in each of the upper and the lower rows; the motors in the first upper and lower rows nearest to the end portion of the connecting member on the side opposite to the motor side are made to correspond to the heald frames of the first group nearest to either the forward side or the backward side where the motor groups are disposed; and the motors of the other upper and lower rows and the heald frames of the other group are made to correspond such that the order of their proximity relative to the first upper and lower rows to which the motors belong coincides with the order of proximity relative to the first upper and lower rows to which the heald frames belong.

- Referring to FIGS. 1 through 6, a
shedding device 10 is used as an electric shedding device which forms a warp shedding by reciprocating upward and downward a plurality ofheald frames 16 arranged at intervals in the forward and backward direction between right andleft frames heald frames 16. In FIG. 1, a warp is moved in a direction perpendicular to a sheet by a let-off from a warp beam not shown, while a weft is run from the left side to the right side or vice versa). - The
heald frames 16 are divided, according to their arrangement positions in the forward and backward direction of the weaving machine, into a first heald frame group including a plurality of heald frames located on the forward side (cloth fell side) and a second heald frame group including a plurality of heald frames located on the backward side (opposite side to the cloth fell). In the illustration, the weaving machine includes twelveheald frames 16; accordingly, each heald frame group is provided with six heald frames. - The
shedding device 10 comprises a first and a second support mechanisms including a plurality ofsupport mechanisms 20 provided at everyheald frame 16 and supporting thecorresponding heald frames 16 so as to move upward and downward, and a first and a seconddrive mechanism groups support mechanisms 20 of the support mechanism groups. In the illustration, since each heald frame group includes sixheald frames 16, each support mechanism group and each drive mechanism group include six support mechanisms and six drive mechanisms, respectively. - The
support mechanisms 20 of the first support mechanism group are made to individually correspond to theheald frames 16 of the first heald frame group and the drive mechanisms of the firstdrive mechanism group 22 and, driven by the corresponding drive mechanisms, move thecorresponding heald frames 16 upward and downward. Thesupport mechanisms 20 of the second support mechanism group are individually made to correspond to theheald frames 16 of the second heald frame group and the drive mechanisms of the seconddrive mechanism group 24 and, driven by the corresponding drive mechanisms, move thecorresponding heald frames 16 upward and downward. - Each
support mechanism 20 is a known mechanism which connects a pair of right and left V-shaped or Y-shaped swinging levers 26 by means of alink 28 extending in the rightward and leftward direction and connects each swinginglever 26 with theheald frame 16 bysupports 30 extending in the upward and downward direction. Both swinginglevers 26 and thelink 28, the heald frames 16 and thesupports 30 are pivotally connected. - The swinging
lever 26 on the left side is V-shaped, while the swinginglever 26 on the right side is Y-shaped. Both swinginglevers 26 are pivotally connected with thelink 28 at respective one ends of their V- or Y-shaped forms and are pivotally connected with thesupports 30 at their respective other front ends of V- or Y-shaped forms. - The right and left swinging
levers 26 are respectively supported on right and leftsupport shafts 32 common to each of the right and left swinging levers at the base portions of the V- or Y-shaped forms, i.e., at their branching portions so as to swing within a plane extending vertically and laterally. - The
support shafts 32 extend between theframes - Each drive mechanism of the first
drive mechanism group 22 is made to correspond to theheald frame 16 located in the front, that is, theheald frame 16 of the first heald frame group, while each drive mechanism of the seconddrive mechanism group 24 is made to correspond to theheald frame 16 of thesecond heald frame 16 located in the rear. - Each drive mechanism of the first and the second
drive mechanism groups bracket 34 which is assembled on the outer surface of theright frame 14 such that the seconddrive mechanism groups bracket 34 is provided on afloor 38 through aleg portion 36. - Each drive mechanism has a drive source or an
electric motor 40 such as a servomotor assembled into thebracket 34 such that the rotation axis extends in the forward and backward direction, an eccentric joint 44 assembled into anoutput shaft 42 of themotor 40, and an elongated connectingmember 46 pivotally connected with the eccentric joint 44 at one end. - The connecting
member 46 is a long plate-like link and is pivotally connected at the other end with the remaining front end of the Y-shapedright swinging lever 26. The connectingmember 46, however, may be a connecting rod. - Each eccentric joint44, as shown in FIGS. 7 and 8, includes a disk-shaped
cam 48 whose outer face is a cam face; an assembling implement 50 for assembling thecam 48 into theoutput shaft 42 of themotor 40; and ascrew member 52 for assembling thecam 48 into the assembling implement 50 in an eccentric state. The assembling implement 50 is assembled into theoutput shaft 42 by thescrew member 54. - Each connecting
member 46 is fitted on the cam face of thecam 48 at acam follower 56 connected with one end of the connectingmember 46 so as to be relatively moved by abearing 58. Consequently, the eccentric joint 44 of each drive mechanism and thecam follower 56 form a crank chain serving as a mechanism for converting motion for converting the rotational motion of themotor 40 into a reciprocal motion. - The
motors 40 of the first and the seconddrive mechanism groups bracket 34 such that theoutput shafts 42 extend in the forward and backward direction, and arranged in the upper, lower, right and left sides at every drive mechanism group to form the first and the second motor groups respectively. - In the illustration, in both
drive mechanism groups motors 40 form two motor rows arranged in the longitudinal (rightward and leftward) direction of the connectingmember 46. The upper andlower motors 40 are arranged in the same positions in the rightward and leftward direction. - Adjoining
motors 40 of each motor row are made to correspond to heald frames not adjoining in the forward and backward direction among the heald frames 16 corresponding to thedrive mechanisms 22 or 24 (that is, the first or the second motor group) to which the adjoiningmotors 40 belong. - For this reason, the
motors 40 forming the upper motor row among the motors of the firstdrive mechanism group 22 are made to correspond to the heald frames 16 in the odd numbered positions from the front side, while themotors 40 forming the lower motor row are made to correspond to the heald frames 16 in the even numbered positions from the front side. - On the other hand, among the motors of the second
drive mechanism group 24, themotors 40 forming the upper motor row are made to correspond to the heald frames 16 in the even numbered positions from the front side, while themotors 40 forming the lower motor row are made to correspond to the heald frames 16 in the odd numbered positions from the front side. - Also, the first
drive mechanism group 22 is disposed on the forward side in the forward and backward direction, and themotors 40 forming each motor row of the firstdrive mechanism group 22 are made to correspond to the heald frames such that the nearer the motors are to the end portion of the connectingmembers 46 on the side opposite to the motors (frame 14 side), they correspond to the more forward heald frame. On the other hand, the seconddrive mechanism group 24 is disposed on the backward side in the forward and backward direction and themotors 40 forming each motor row of the seconddrive mechanism group 24 such that the nearer the motors are to the end portion of the connectingmembers 46 on the opposite side to the motors, the more backward heald frame they correspond to. - Concretely, the
motors 40 forming the upper motor row of the firstdrive mechanism group 22 are connected with the heald frames through a support mechanism or the like such that the motors in the order from the side of theframe 24 respectively correspond to the first, the third and the fifth heald frames from the forward side. On the other hand, themotors 40 forming the lower motor rows of the firstdrive mechanism group 22 are connected with the heald frames through a support mechanism or the like such that the motors in the order from the side of theframe 24 respectively correspond to the second, the fourth and the sixth heald frames from the forward side. - Likewise, the
motors 40 forming the upper motor row of the seconddrive mechanism group 24 are connected with the heald frames through a support mechanism or the like such that the motors in the order from the side of theframe 24 respectively correspond to the twelfth, the tenth and the eighth heald frames from the forward side. On the other hand, themotors 40 forming the lower motor row of the seconddrive mechanism group 24 are connected with the heald frames through a support mechanism or the like such that the motors in the order from the side of theframe 24 respectively correspond to the eleventh, the ninth and the seventh heald frames from the forward side. - The relations between the
motors 40 and the heald frames 16 such as above are shown in FIGS. 5 and 6. FIG. 5 shows the position numbers from the front side of the heald frames 16 corresponding to themotors 40 of the upper motor row, while FIG. 6 shows the position numbers from the forward side of the heald frames 16 corresponding to themotors 40 of the lower motor row. In the drawings, theArabic numerals 1 through 12 placed inside themotors 40 indicate the order of the corresponding heald frames. - The correspondence relation between each
motor 40 of the firstdrive mechanism group 22 and eachheald frame 16 can be explained as follows. Six heald frames 16 are divided into three groups consisting of adjoining heald frames 16 corresponding to two motors in the upper and the lower rows of the first drive mechanism group, in more detail, a group including the heald frames of position Nos. 1 and 2, a group including the heald frames of position Nos. 3 and 4, and a group including the heald frames of position Nos. 5 and 6, and the twomotors 40 in the first upper and lower rows nearest to the end portion of the connectingmember 46 on the side opposite to the motors are made to correspond to the heald frames (including the heald frames of position Nos. 1 and 2) in the first group nearest to the forward side where thefirst mechanism group 22 is located, while the twomotors 40 in the other upper and lower rows and the heald frames of the other group are made to correspond such that the order of proximity in the upper and lower rows to which themotors 40 belong relative to the first upper and lower rows coincides with the order of proximity of the group to which the heald frames belong relative to the first group. - In the
shedding device 10, with the rotation of themotors 40, thecam 48 of the corresponding eccentric joint 44 is rotated in an eccentric state, so that the corresponding connectingmember 46 is reciprocated in the rightward and leftward direction. Thereby, the corresponding swinging levers 26 are swung, thesupport body 30 is reciprocally moved upward and downward, and accordingly, the corresponding heald frames 16 are reciprocally moved upward and downward. - The rotation of each
motor 40 of the first and the seconddrive mechanism groups drive mechanism groups - In the
shedding device 10, adjoiningmotors 40 forming each motor row of thedrive mechanism groups motors 40 in each motor row is enlarged, and accordingly, the distance between adjacent mechanisms for converting motion which are individually assembled into theoutput shafts 42 of themotors 40 and adjacent in the forward and backward direction can be enlarged. - As a result, mutual intervention between the mechanisms for converting motion corresponding to adjoining
motors 40 in each motor row such as thecam 48 as well as thescrew member 52 and the connectingmember 46 opposing thereto can be prevented. Namely, even if such a mechanism for converting motion traverses the front or the rear of at least one mechanism for converting motion, the sum of the thicknesses of the adjoining mechanisms for converting motion, particularly, the sum of the thicknesses of the eccentric joint 44 and thecam follower 56 of the mechanisms for converting motion is not limited to be the arrangement pitch or less of the heald frames 16 adjoining in the forward and backward direction. Furthermore, the mechanical strength of the mechanism for converting motion can be enhanced without enlarging the space to arrange themotors 40. - In the
shedding device 10, the first and the seconddrive mechanism groups motors 40 of the firstdrive mechanism group 22 nearer to theframe 14 are connected with the heald frames 16 positioned more forward, while themotors 40 of the second drive mechanism group nearer to theframe 14 are connected to the heald frames 16 positioned more backward, respectively. Therefore, as a result of the above, mutual intervention between the mechanisms for converting motion connected with the motors within the same motor row can be more surely prevented. - In the
shedding device 10, furthermore, since the first and the seconddrive mechanism groups many motors 40 can be more efficiently arranged without lowering the strength of the members composing the mechanisms for converting motion. - In the foregoing embodiment, while the motors are disposed in three by two rows in each drive mechanism group, the number of the motors in the upper and the lower motor rows and the method of arranging them are not restricted to the above embodiment. Also, three or more motor rows may be formed in each drive mechanism group, or, in place thereof, one or more other motors may be disposed above or below the one motor row.
- FIG. 9 shows an embodiment of a first and a second
drive mechanism groups drive motors 40. Eightmotors 40 of each drive mechanism group form two motor groups arranged in the upward, downward, rightward and leftward directions, and each of the two motor rows arranged in two rows has four motors in the longitudinal direction of the connectingmembers 46. - Adjoining
motors 40 within each motor row are made to correspond to the heald frames not adjoining in the forward and backward direction among the heald frames 16 corresponding to the drive mechanisms (i.e., motor groups) to which the motors belong. - Consequently, among the motors of the first
drive mechanism group 62, themotors 40 forming the upper motor row are made to correspond to the heald frames 16 in the odd numbered positions from the forward side, while themotors 40 forming the lower motor row are made to correspond to the heald frames 16 in the even numbered positions from the forward side. - On the other hand, among the motors of the second
drive mechanism group 64 themotors 40 forming the upper motor row are made to correspond to the heald frames 16 in the even numbered positions from the forward side, while the motors forming the lower motor row are made to correspond to the heald frames 16 in the odd numbered positions from the forward side. - Furthermore, as for the
motors 40 forming each motor row of the firstdrive mechanism group 62, the nearer motors to the end portion of the side opposite to the motors (frame 14 side) of the connectingmember 46 are made to correspond to the heald frames positioned more forward. On the other hand, the nearer themotors 40 forming each motor row of the seconddrive mechanism group 64 are to the end portion of the connectingmember 46 on the side opposite to the motors, the more backward heald frames they are made to correspond to. - The correspondence relation between the motors and the heald frames such as above is shown in FIG. 9 with the letters “upper side” and “lower side” as well as the Arabic numerals of 1 through 16 indicating the order of the corresponding heald frames from the forward side. The positions respectively of the
motors 40 in the upper motor row and those in the lower motor row are displaced in the rightward and leftward direction. - Each
motor 40 is assembled into the common frame by a common bracket. The positions of themotors 40 in the forward and backward direction are the same in each drive mechanism group, that is, each motor group. Therefore, the length dimensions of the output shafts of therespective motors 40 are different. - FIG. 10 shows an embodiment of a
drive mechanism group 66 which is a shedding device using eight drive motors, in which a motor group forming two motor rows with eightdrive motors 40 are arranged in the upward, downward, rightward and leftward directions, four each in one row in the longitudinal direction of the connecting member. Thedrive mechanism group 66 and themotors 40 are related in a similar manner to thedrive mechanism group 62 and themotors 40 in FIG. 9. Such a relation between the motors and heald frames is shown in FIG. 10 with theArabic numerals 1 through 8 indicating the order of the corresponding heald frames from the forward position. - FIG. 11 shows an embodiment of a drive mechanism group68 (or two
drive mechanism groups drive motors 40 for ten heald frames and support mechanisms) including a motor group forming two motor rows with tendrive motors 40 arranged in the upward, downward, rightward and leftward directions in the upper and the lower two rows each having five motors in the longitudinal direction of the connectingmember 46. - The upper and the lower motors are disposed in the same positions in the rightward and leftward direction. Like the
drive mechanism group 62 and themotors 40 shown in FIG. 9, thedrive mechanism group 68 and themotors 40 are related to predetermined heald frames except the number of motors. Such a correspondence relation between the motors and the heald frames is shown in FIG. 11, with the order of the corresponding heald frames from the forward side indicated by theArabic numerals 1 through 10 under themotors 40. Also, among the Arabic numerals in two rows in the rightward and leftward direction, the numerals in the upper row correspond to the lower motor row, and the numerals in the lower row correspond to the upper motor row. - In case two
drive mechanism groups mechanism groups drive mechanism groups Arabic numerals 1 through 10 indicating the order from the forward side as well as numerals (11) through (20). Also, the embodiment shown in FIG. 11 has the similar constitution to those shown in FIGS. 2 and 3 except that the corresponding relation between the number of thedrive motors 40 and the heald frames is different. - FIG. 12 shows embodiments of a drive mechanism group72 (or two drive mechanism groups 72, 74 each having ten heald frames and ten
drive motors 40 for a support mechanism) having tendrive motors 40 arranged in the upward, downward, rightward and leftward directions in three rows in the longitudinal direction of the connecting member such that four motors are arranged in each of upper and lower two rows with two motors on the top row. - The drive mechanism groups72, 74 and the
motors 40 are related to predetermined heald frames like thedrive mechanism groups motors 40 as shown in FIG. 11, except that the motor rows are different. The correspondence relation of the motors and the heald frames such as above are shown in FIG. 12 with theArabic numerals 1 through 10 and (11) through (20) below themotors 40, indicating the order of the corresponding heald frames from the forward side. Among the Arabic numerals arranged in three rows in the rightward, leftward, upward and downward directions, the numerals on the top row correspond to the lowest row of the motors, the numerals in the second row correspond to the second motor row, and the numerals in the third row correspond to the top motor row. - FIG. 13 shows an embodiment of a
drive mechanism group 76 including a motor group in which twelve drivemotors 40 are arranged upward, downward, rightward and leftward directions to form three motor rows in the upward and downward direction, each row having four motors in the longitudinal direction of the connectingmember 46. The upward anddownward motors 40 are displaced in the rightward and leftward direction with respect to their positions. The fourmotors 40 in each row respectively oppose to one connecting member connected with the farthest motor from the end portion of the connecting member on the side opposite to the motor. - The
drive mechanism group 76 and themotors 40 are related to predetermined heald frames, like thedrive mechanism group 62 and themotors 40 in FIG. 9 except that the array of the motors are different. The correspondence relation of the motors and the heald frames such as above is shown in FIG. 13 with theArabic numerals 1 through 12 inside themotors 40 indicating the order of the corresponding heald frames from the forward side. - FIG. 14 shows an embodiment of a
