Description
- This invention relates to a weaving loom, more particular to a weaving loom, which is provided with a circulating magnetic shuttle that circulates along an endless loop.
- In a conventional weaving loom, a reciprocating shuttle reciprocates along a straight race rail. When in a picking motion, the flying speed of the reciprocating shuttle is accelerated from 0 to a high constant speed, and is then braked and decelerated to 0. Subsequently, the same picking motion is repeated in the opposite direction, thereby increasing largely the weft picking time.
- To overcome the time-consuming problem, the applicant heretofore proposed an improved weaving loom, which is provided with a circulating magnetic shuttle, see US 4 762 153 A which discloses a weaving loom according to the preamble of claim 1. Referring to Fig. 1, the improved weaving loom 1 is shown to include a
driving wheel 111 that drives adriving belt 113 to circulate. A series ofmagnets 114 is secured to thebelt 113 for attracting and driving amagnetic shuttle 13 to circulate along an endless loop. Theshuttle 13 picks a weft 160 with the assistance of aweft swinging rod 16, and then moves the weft 160 over areed assembly 20, which is held on aswing arm 221 that is fixed on a rotatingshaft 222. When the rotatingshaft 222 rotates, thereed assembly 20 beats theweft 16. Two series of guidingrollers 12 are disposed respectively around adriving wheel 111 and a drivenwheel 112 so that, when moving along two curved portions of arace rail 101, theshuttle 13 does not take off and deviate from therace rail 101 because of the centrifugal force that is generated. The conventional weaving loom 1 suffers from the following disadvantages: - 1. The structure of the weaving loom 1 is relatively
complicated. For example, a relative
long race rail 101 is needed to be disposed around thedriving belt 113, thereby serving as a passage of theshuttle 13. In addition, a large number of guidingrollers 12 are disposed around thedriving wheel 111 and the drivenwheel 112 so as to guide theshuttle 13 to move along a curved path, thereby preventing the deviation of theshuttle 13 from an endless loop. As a result, it is difficult to manufacture the weaving loom 1, thereby increasing the manufacturing costs. - 2. The
shuttle 13 cannot move smoothly on therace rail 101. Ideally, the portion of thebelt 113 between thedriving wheel 111 and the drivenwheel 112 should be in a horizontal position. However, during the movement of themagnets 114 between thedriving wheel 111 and the drivenwheel 112, the portion of thebelt 113, to which themagnets 114 are attached, is slightly lower than the remaining portion of thebelt 113, which is located between thedriving wheel 111 and the drivenwheel 112 due to the weight of themagnets 114. The larger the distance between thewheels magnets 114 from their predetermined circulating path. It is unavoidable, when weaving wider fabrics, to increase the distance between thewheels belt 113 andmagnets 114 cannot circulate smoothly at a high speed. Furthermore, because theshuttle 13 moves on therace rail 101, and contacts frequently the guidingrollers 12, it cannot fly smoothly along the endless loop, thereby reducing the weaving efficiency. - 3. It is difficult to maintain and repair the weaving
loom 1. To descend the gravity center of the weaving loom
1 and reduce the vibration of the same, the
race rail 101 and the guidingrollers 12 are disposed on a lower portion of the weaving loom 1 along with the swingingarm 221 and the rotatingshaft 222. Because they are disposed relatively close to each other, it is difficult to maintain and repair the weaving loom 1. -
- The object of this invention is to provide an improved weaving loom, which is provided with a circulating magnetic shuttle and which has a simple structure that can be easily maintained and repaired and that can be operated smoothly, thereby increasing the weaving efficiency.
- According to this invention as defined in independent claim 1, a weaving loom includes a transmission. The transmission includes a driving wheel, a driven wheel, an endless driving belt that extends around the driving wheel and the driven wheel, and at least one magnet unit, which is secured to an inside surface of the belt for attracting and driving the shuttle to circulate on a machine frame. Each of the driving wheel and the driven wheel is formed with an annular groove, within which the shuttle and the magnet unit move in such a manner that the shuttle is attracted onto the magnet unit.

frame 50 includes a fixedupper race rail 501 and a fixedlower race rail 502. Each of a bottom surface of theupper race rail 501 and a top surface of thelower race rail 502 is formed with an open-endedlongitudinal guide slot 503, and two fixed anti-wearlongitudinal plates 504, which extend respectively into two side portions of theguide slot 503 to locate theshuttle 52 between one of the upper andlower race rails longitudinal plates 504, thereby confining theshuttle 52 within theguide slot 503. Theshuttle 52 is attracted onto themagnet unit 514 during the movement of theshuttle 52 within the upper andlower race rails - Each of the
guide slots 503 of the upper andlower race rails shuttle 52 moves into theguide slot 503, and ashuttle outlet 503", from which theshuttle 52 leaves thelongitudinal guide slot 503. Twopressing roller units 505 are located respectively near the shuttle inlets 503' of theguide slots 503. Each of thepressing roller units 505 includes a row of pressing rollers 505', which are arranged on a horizontal line and which abut against an outer side surface of thedriving belt 513. - Referring to Fig. 4, the inside surface of the
driving belt 513 is formed with two longitudinal rows ofteeth 515, between which the magnet units 513 (only one is shown) are disposed. Each of themagnet units 514 includes an elongated and corrugatedlongitudinal plate 516, which is fixed on thedriving belt 513 so as to define a plurality of magnet receiving spaces 516' between thelongitudinal plate 516 and thedriving belt 513, thereby receiving a plurality ofmagnets 516" fittingly therein. - The
driving wheel 511 and the drivenwheel 512 have the same structure.

Thedriving wheel 511 has a rim that is formed with anannular groove 517, within which themagnet unit 514 and theshuttle 52 move in such a manner that theshuttle 52 is attracted onto themagnet unit 514. Thedriving wheel 511 is sleeved fixedly on a rotatingshaft 518. - Referring to Figs. 2 and 3, the
beating mechanism 6 includes areed assembly 60 consisting of a row ofreed dents 61, and aswinging device 62. Thereed dents 61 are disposed on asley 63. Theswinging device 62 is connected fixedly to thereed assembly 60 for swinging the same, and includes a swingingarm 621 and a rotatingshaft 622, which are interconnected fixedly. Each of thereed dents 61 has a horizontal portion so as to form a flat shuttle guide-way 601 thereon, thereby guiding theshuttle 52 into the shed. Themachine frame 50 is provided with an elongated wedge-shaped divider 53 and an elongated wedge-shaped jointer 55, which are disposed fixedly on two sides of thereed assembly 60. Thedivider 53 is adjacent to and is located between thedriving wheel 511 and the shuttle inlet 503' of theguide slot 503 in thelower race rail 502, and has an abutment end that is adjacent to the shuttle guide-way 601, a flat horizontaltop surface 531 that is flush with the shuttle guide-way 601, and a wedge-shaped end 532. As such, theshuttle 52 moves from thedriving wheel 511 along thedriving belt 513 to the wedge-shaped end 532 of thedivider 53, thereby separating theshuttle 52 and themagnet unit 514 at the wedge-shaped end 532. Subsequently, theshuttle 52 moves from the wedge-shaped end 532 to thetop surface 531 of thedivider 53 and the shuttle guide-way 601 on thereed assembly 60.
