Definitions
- camshaft mechanics which include a series of oscillating levers in number equal to that of the heald frames to be mounted on the loom, each oscillating lever being designed to be coupled to the one of the frames and equipped with two rollers which cooperate with the two tracks of a complementary cam driven in rotation by a common shaft.
- the cams which are generally in number between four and twelve, must be mounted on their drive shaft.
- the mechanical frame defines two half bearings on which are attached collars or flanges forming the other half of the bearings after the common shaft fitted with cams has been put in place on the half bearings formed by the frame.
- This technique induces inaccuracies in the positioning of the shaft relative to the frame, so that the value of the distance between the axis of the camshaft and the axis of articulation of the oscillating levers cannot be guaranteed with precision, as well as the parallelism of these axes.
- the invention more particularly intends to remedy by proposing an armor mechanism in which the mounting and dismounting of the cams can be carried out on the machine itself, without loss of time, without using specific tools and without affecting the precision of the positioning of their common drive shaft with respect to the mechanical frame and the oscillating levers cooperating with these cams.
- the invention relates to a cam armor mechanism for a weaving loom, this mechanism comprising several cams mounted on a common drive shaft and provided with tracks of follower rollers themselves mounted on oscillating levers.
- this drive shaft being supported by means of two orifices made in two integral parts of the mechanical frame and one of which is crossed by this tree.
- This mechanism is characterized in that the aforementioned shaft extends, from the first orifice and in the direction of the second orifice, over a length less than the distance between these orifices, while removable means forming an extension and support connect the end of this shaft located between these orifices at the second orifice and while the difference between the distance between the orifices and the length over which the shaft extends between these orifices is greater than the width of a cam.
- a space is created between the end of the shaft and the part of the frame in which the second orifice is formed, which makes it possible to use this space, before installation of the means forming extensions or after removal of these, to put the cams on the shaft already installed in the frame.
- the cams are placed individually on their drive shaft, so that it is not necessary to use a barrel, each cam having a mass and a size compatible with easy handling.
- an armor mechanism can incorporate one or more of the following characteristics taken in all technically admissible combinations: -
- the means forming an extension and support carry or form a support bearing for the end of the shaft located between the two orifices.
- the means forming an extension and support comprise an endpiece capable of being attached to the end of the shaft and of exerting on the cams mounted on this shaft an axial force for blocking the rotation of the cams by adhesion.
- This tip is advantageously secured in rotation to the end of the tree. It can extend axially up to the level of the second orifice of the frame in which it is inserted, with the interposition of a bearing.
- the means forming an extension and support comprise a sleeve removably mounted in the second orifice and which extends in the direction of the end of the shaft.
- This sleeve advantageously extends to the level of this end which it surrounds, with the interposition of a bearing.
- the sleeve can extend axially up to the level of this nozzle, with the interposition of a bearing.
- the invention also relates to a weaving loom equipped with a weaving mechanism as described above. Such a trade is more economical, easier to configure and more reliable than known trades.
- the invention also relates to a method of assembling an armor mechanism as described above and, more specifically, a method which comprises steps consisting in: - putting in place the common cam drive shaft in the mechanical engineering; move at least one cam, in a direction generally perpendicular to a longitudinal axis of the shaft and in a volume defined between the free end of this shaft and a monobloc part of the frame, until substantially aligning a central bore of this cam with this tree; then move this cam in a direction generally parallel to the longitudinal axis of the shaft and in a direction directed opposite the aforementioned part of the frame, until surrounding the shaft with this cam and removably install means forming an extension and support and connecting this end to an orifice formed in the aforementioned part of the frame.
- the weaving loom M represented in FIG. 1 comprises several heald frames, only one of which is visible in this figure with the reference 1.
- the different frames of the loom M are driven by a movement of vertical oscillations represented by the double arrow Fi and printed by a cam mechanism 10 whose output levers 11 respectively attack connecting rods 12 associated with bent levers 13 and connected together and to the frames by connecting rods 14.
- the levers 11 are provided in a number equivalent to the number of frames of smooth 1 and pivotally mounted, as shown by the double arrow F 2 , around the axis longitudinal X ⁇ 5 of a common shaft 15 supported by the frame 16 of the mechanism 10.
- the mechanism 10 also comprises several complementary cams 18 each defining two tracks 18A and 18B on which the rollers 19A and 19B respectively carried by the levers 11.
- the cams 18 are mounted on a common shaft 20 which is supported by the frame 16 and of which a first end 20A carries a wheel 21 with conical teeth intended to cooperate with a pinion 22 with conical teeth and forming a reduction gear allowing the drive of the shaft 20 around its longitudinal axis X 2 o-
- the frame 16 is pierced with two orifices 16A and 16B of circular section and whose respective central axes are generally aligned with one another and with the axis X 2 o when the shaft 20 is in place in the frame 16.
- the orifices 16A and 16B are respectively formed in an intermediate rib 16C and in one side 16D of the frame 16 which are in one piece.
- a bearing 23 is disposed in the orifice 16A and makes it possible to support the shaft 20 which extends on either side of the rib 16C. From the orifice 16A, the shaft 20 extends in the direction of the orifice 16B over a length L 20 which is strictly less than the distance Di 6 between the orifices 16A and 16B, that is to say the distance between the facing faces of the parts 16C and 16D of the frame 16.
- a space E is thus created, shown in gray in FIG. 3, of width 1 E equal to the difference of the distance D ⁇ 6 and the length L 2 o .
- the space E can be used to set up the cams 18 on the shaft 20 insofar as the width 1 E is greater than the width l ⁇ 8 of the cams 18. In fact, as shown in FIG.
- a cam 18 can be inserted into space E in the direction of arrow F 3 , that is to say in a direction generally perpendicular to the axis X 20 , this cam 18 being inserted between the side 16D of the frame 16 and the free end 20B of the shaft 20.
- the central bore 18C of the cam 18 is generally aligned with the axis X 20 , it is possible to move this cam in the direction of arrow F 4 in FIG. 3, that is to say in the direction of the rib 16C, so that this cam comes to surround the end 20B of the shaft 20.
- the angularly cam 20 for aligning an axial drilling thereof provided for this purpose with an angular indexing rod 24 previously placed in the corresponding aligned holes of the cams already installed on the shaft 20.
- the end 20B of the shaft 20 is connected to the side 16D of the frame 16 by means of a nozzle 40 and a sleeve 50 secured respectively to the shaft 20 and with the side 16D.
- the end piece 40 is intended to extend the shaft 20 in the direction of the orifice 16B and it is provided with a groove 40C intended to cooperate with a tenon 20C provided on the end 20B of the shaft 20, which allows securing in rotation the elements 20 and 40 and thus securing the angular drive of the nozzle 40 by the shaft 20.
- the nozzle 40 comprises a skirt 40D intended to surround the end 20B of the shaft 20 and to come to bear on the cam 18 closest to this end 8, thus exerting on the cam stack 18 a force represented by the arrows F 5 and directed towards a ring 25 mounted on the shaft 20 and forming a shoulder. This effort allows the cams to block in rotation by adhesion.
- the tip 40 is immobilized on the shaft 20 by means of screws 41 received in holes 40E of the tip 40 and in threads 20E of the shaft 20.
- the sleeve 50 is immobilized on the side 16D of the frame 16 by means of four screws 51, two of which are visible in Figure 2 and which penetrate into threads located radially outside the orifice 16B.
- This sleeve 50 includes a flange 50A for bearing on the external face of the side 16D and is extended in the direction of the rib 16C by coming to surround the end piece 40 and the end 20B of the shaft 20.
- a series of rollers 60 is interposed between the external radial surface 40F of the end piece 40 and the internal radial surface 50F of the sleeve 50, which makes it possible to create a support bearing for the end 20D.
- Lugs 50G immobilized on the sleeve 50 by screws 50J make it possible to hold the rollers 60 in position.
- a plug 50K is removably mounted in the central opening of the sleeve 50 and makes it possible to hide the end piece 40 and the screws 41.
- the elements 40 to 60 make it possible to extend the shaft 20, so that its end is supported by the side 16D at the level of the orifice 16B.
- the bearing formed by the rollers 60 is not necessarily disposed at the level of the skirt 40D of the end piece 40 and could be arranged in any place along the length of the end piece 40.
- the tip 40 extending the shaft 20 extends to the interior of the bore 16B where it is received with the interposition of a bearing formed of rollers 60.
- Screws 41 make it possible to secure the end piece 40 at the end 20B of the shaft 20, this end piece being associated with a washer 70 making it possible to exert on the cams 18 an axial force F 5 for fastening in rotation by adhesion.
- a plug 50K makes it possible to isolate the end piece 40 and the screws 41 from the outside.
- a space E is also provided by which the cams 18 can be put in place and removed as required.
