Detailed description of the invention
Such as Fig. 1, it it is a specific embodiment of the frame shedding motion of the present invention, this frame shedding motion is mainly by axle bed 21,22, eccentric shaft 3, swing arm 8 and cam 9 form, eccentric shaft 3 is bearing on axle bed 21,22, and several swing arms 8 are rotatably coupled on eccentric shaft 3, and cam 9 is located at swing arm 8 and is swung side.Under in working order, swing arm 8 and cam 9 are in engagement, and cam 9 rotates and drives swing arm 8 to swing, and swing arm 8 upper end connects connecting rod (not shown) and corresponding drive mechanism drives heald frame to do upper and lower opening motion. In a non-operative state, for instance when maintenance or replacing cam, swing arm 8 needs to separate with cam 9. The shedding mechanism of the present invention drives swing arm 8 opposing cam 9 to rotate by the rotation of eccentric shaft 3, thus convergence cam 9 being engaged with, or away from cam 9 disconnected.
Such as Fig. 2, the eccentric shaft 3 of the present invention is designed such that it includes the two axial ends section of coaxial inner conductor 34,35 and to be arranged between this two axial ends section and have the eccentric throw of the axle stage casing 33(of eccentric throw E and the axial line in axle stage casing 33 and the axial line of two axial ends section 34,35 with the axial line of this two axial ends section be E), eccentric shaft 3 is bearing on the first axle bed 21 and second axle bed 22 of correspondence respectively by two axial ends section 34,35, and swing arm 8 is rotatably coupled on the axle stage casing 33 of eccentric shaft 3. Thus, under in working order, swing arm 8 is engaged with cam 9, such as Fig. 3; Swing arm 8 is subject to the driving of cam 9 and swings thus driving integrated box movement around axle stage casing 33 axial line; And when needing swing arm 8 to separate with cam 9 in a non-operative state, then swing arm 8 is subject to eccentric shaft 3 and drives, around eccentric throw two axial ends section axle center alignment away from cam 9 direction swing a suitable angle (engagement separation angle), it is made to separate with cam 9, such as Fig. 4 when needs swing arm 8 is engaged with cam 9, swing arm 8 swings an engagement separation angle under eccentric shaft 3 drives and engages with cam 9 to convergence cam 9 direction. And engagement separation angle in shedding motion of the present invention is adjustable.
Further, for making the shaft end section 34,35 supporting structure on axle bed 21,22 more succinct, axle bed 21,22 is provided with the support holes 201,202 suitable with corresponding shaft end section 34,35 diameter, and two axial ends section is directly rotatably supported in corresponding support holes.
Above-mentioned engagement separation angle is adjustable in the present invention, and adjusts and realized by position-limiting unit 31 and screw rod 13,14. At least one shaft end section one circumferentially disposed on position-limiting unit is set, the present embodiment is to arrange position-limiting unit in left side shaft end section 34, and two screw rods 13,14 is arranged on corresponding on the left side axle bed 21 of left side shaft end section 34, and it is positioned at position-limiting unit 31 on the circumferential position rotated with two axial ends section 34,35 axial line, by the adjustment to screw rod 13,14, namely the rotational angle controlling position-limiting unit 31 engages separation angle, thus controls swing arm (8) and engages separation angle with cam (9).
In order to better connect installation first module, the axle bed at eccentric shaft 3 two ends carries out different designs according to whether having position-limiting unit on it, therefore axle bed includes the first axle bed 21 and the second axle bed 22, the shaft end section 34 arranging position-limiting unit 31 is bearing in the support holes of the first axle bed 21, the shaft end section 35 being not provided with position-limiting unit 31 is bearing in the support holes of the second axle bed 22, and position-limiting unit 31 does the rotation of the axial line around two axial ends section 34,35 in the support holes 201 of the first axle bed 21.
Above-mentioned position-limiting unit can be screw 31, it is also possible to be rivet, and the present embodiment adopts screw 31. Therefore, the circumference of the shaft end section corresponding to having position-limiting unit is provided with the screw for connecting above-mentioned screw 31 or rivet or rivet hole.
A preferred structure for the shaft end section with position-limiting unit is, the periphery of this shaft end section arranges toroidal cavity 36, it is consequently formed the groove bottom 37 of cylinder, above-mentioned screw or rivet hole are arranged in this groove bottom, screw is screwed in the screw in this groove bottom (or in rivet hole that rivet is in this groove bottom), and is in toroidal cavity 36. Therefore, the diameter with the shaft end section 34 of position-limiting unit is greater than the diameter of the shaft end section 35 being not provided with position-limiting unit.
For the preferred structure of the above-mentioned shaft end section with position-limiting unit, the first axle bed 21 of its correspondence is provided with two screws 211 for the two screw rods 13,14 that spins. first axle bed 21 of the present embodiment is the bilateral symmetry being symmetrical in vertical center line, therefore support holes is centrally located in this symmetrical center line, two screws 211 be arranged on this symmetrical center line symmetrical both sides and with support holes 201 vertically through, two screw rods 13, 14 are rotatably connected in a screw 211 respectively, screw rod end extend in support holes, change by extending into the length of support holes, screw rod end is made to be in position-limiting unit 31 around two axial ends section 34, on different circumferential positions when 35 axial lines rotate, to shaft end section 34, the rotational angle of 35 is defined, thus described engagement separation angle is adjusted, this adjustment is very convenient, if turn screw rod, it is made to move axially to suitable position, such as: turn screw rod 13, make swing arm 8 be in and preferably engage initial position, such as Fig. 5, turn screw rod 14, makes swing arm 8 be in and preferably separates initial position, such as Fig. 6.
The shedding motion of the present invention is placed in a casing 1, and the axle bed 21,22 for supporting eccentric shaft 3 is separately positioned on two relative inwalls of casing 1. The rotation of eccentric shaft 3 is by manual actuation, therefore the handle 6 for manual actuation it is provided with, this handle 6 is connected on disk cover 5, disk cover 5 is arranged on the casing lateral wall corresponding to the first axle bed 21, this disk cover 5 is connected with corresponding shaft end section 34 through casing 1 by screw, making disk cover 5 be connected position one with eccentric shaft 3, turning handle 6 makes eccentric shaft 3 rotate.
For the ease of after swing arm 8 separates with cam 9, the several swing arms 8 being rotationally connected with on eccentric shaft 3 can be in consistent position, bottom inside casing 1 arranges location bar 7, and swing arm 8 is in that, when cam 9 is in the maximum separation position under released state, swing arm 8 touches this location bar 7. Being provided with inclined-plane 71 on the bar 7 of location, when this inclined-plane 71 swings to maximum separation position with swing arm 8, the form of one side matches.
The invention is not restricted to the embodiments described, such as Fig. 7, the support holes hole wall of the first axle bed 21 arranges toroidal cavity 38, this annular groove 38 position-limiting unit 31 corresponding to connecting in shaft end section 21, position-limiting unit 31 is contained in this annular groove 38, and two screw 211 and this annular groove 38 vertically through, and other structures are same as the previously described embodiments, constitute so again second embodiment.
