Description

Shuttle machine and knitting machine having the same

The present invention relates to a hopper machine for a knitting machine (for example, a rotary cam or a dobby type sling machine) and a knitting machine having the same.

In the field of weaving, the use of a shed machine having a set of output rods mounted around a common shaft member is well known. Each output rod is coupled to a heald frame of the knitting machine via a rod assembly and connects a plurality of rods currently designated as a "drawing system". The alternating oscillation of each of the output rods about one of the longitudinal axes of the common shaft member drives the heddle frame that is coupled to the associated output rod to move vertically. Thus, the oscillations impart a movement to the warp of one of the fabrics to be made such that one of the fabric patterns is defined in accordance with the swing of the heald frame and the relative position of the yarn carried by a frame heddle. The transfer of the motor torque of the braiding machine to the different shaft members and output rods of the machine causes friction of the metal parts and causes significant heat loss to the machine. In view of the ever-increasing operating speeds of such machines, it is known from EP-A-0 140 800 to use needle bearings between the output rod and the common shaft member and the axial abutment between two adjacent rods. The active lubrication of these mechanical components and their cooling play a decisive role in the proper operation of the machine over time. Lubrication reduces friction of moving mechanical parts, eliminates heat generated by friction and captures metal particles and possibly debris in the contact areas created in the machine. Lubrication further reduces operational noise and protects the path from oxidation and corrosion. The common shaft member supporting the output rod is particularly critical to the area where the lubricant is supplied immediately after starting and immediately during operation of the machine. A particular known machine includes a lubrication system that includes a hydraulic pump and a conduit for delivering a liquid lubricant toward the shaft. However, such a solution has the disadvantage that it is necessary to apply components (especially pipes) that are added to the framework of the machine, and the positioning of such components is not always guaranteed. These flexible pipes are subject to leakage and installation problems. Furthermore, the installation of the machine becomes relatively complicated due to the pipe connections to be formed. A particular machine, such as a mechanism with a cam, is housed in one of the lower sides of the braiding machine in a reduced space, which interferes with maintenance operations, particularly when the machine is redundantly equipped with flexible tubing. Finally, the machine lacks adaptability when the machine has to be configured for a given knitting machine. IT-B-1251843 describes a rotary dobby machine comprising a pump for drawing lubricating oil contained at the bottom of one of the frames of the dobby. The pump includes a fixed bend guide and a plurality of cavities for trapping oil for supplying the shaft drive to one of the machine via one of the first plates traversing the frame (on which the fixing member is mounted) oil. The oil is introduced into the fixed guide by a smoothing wheel that rotates nearby and moves within the guide. The circuit includes a filter conduit directly connected to one of the discharge orifices of the body of the pump and a conduit formed in one of the shaft members of the dobby and directly connected to a suction orifice of the pump body for dispensing lubricant . The filter conduit and the distribution conduit are positioned between a first plate and a second plate of the frame of the machine. This dobby has the drawback that the smooth wheel is immersed in the oil from the bottom of the frame and thus takes up a lot of space. In addition, the shaft of the rod cannot be lubricated. In addition, maintenance of the filter requires the entire machine to be exploded to the extent that the machine is mounted between the two plates of the frame.

Accordingly, the present invention seeks to find a remedy for the deficiencies of the prior art mentioned above by proposing a novel sling machine that is particularly reliable, compact and easy to maintain. The subject matter of the present invention is a shed machine for a knitting machine, the shed machine comprising a swing output rod mounted to surround one of the frames belonging to the machine and mounted on one of the machines Rotating the common shaft member, the boring machine includes a lubrication system including a lubricant circuit, a pump for circulating the lubricant in the lubricant circuit, the pump including a pump body and located therein At least one movable pumping component of the pump body, the pump body being provided with one passage for pumping lubricant and one passage for discharging lubricant, the discharge passage being connected to one of the secondary conduits of the lubricant circuit, A secondary conduit is formed in the frame. The lubrication system also includes a component for dispensing lubricant to at least one component to be lubricated of the machine, the dispensing component being coupled to a secondary conduit of the lubricant circuit. According to the invention, a passage for pumping lubricant is connected to one of the primary loops of the lubricant circuit, the primary conduit being formed in the frame. According to the invention, the suction channel faces the primary conduit and leads to the primary conduit and the discharge channel faces the secondary conduit and leads to the secondary conduit. By means of the invention, the pump body is directly connected to the lubricant circuit via the frame, which avoids the implementation of flexible pipes, limits the risk of leakage, and facilitates maintenance and manufacture of the machine. In addition, the compactness of the machine has been improved by the absence of such flexible pipes. Further advantageous features of the invention are seen individually or as a combination: - the dispensing member is formed by the common shaft member, the common shaft member comprising: a dispensing conduit formed inside the common shaft member while being a tubular wall defining one of the shaft members, the swinging rod being mounted to the tubular wall; and a dispensing orifice traversing the tubular wall for communicating the dispensing conduit with the exterior of the common shaft member; - the frame including a first a common shaft member supported on the first plate, the lubricant circuit including a supply conduit formed in the first plate, the supply conduit being supplied with a lubricant through the secondary conduit, the lubricant circuit including An orifice supplied by the supply conduit and placed face to face with one of the conduits for supplying the common shaft member and supplying the lubricant distribution conduit; - the frame includes a second plate supported by the common shaft member On the second board, the lubrication system includes a probe for detecting the presence of a lubricant in the lubricant circuit, the detection probe is mounted on the second plate, and the lubricant circuit includes a second plate formed on the second plate Inside And fluidly coupled to one of the detection probes, the probe conduit includes an aperture disposed to face the output conduit of the common shaft member, the output conduit being supplied by the lubricant distribution conduit and to be lubricated a probe is supplied to the probe conduit; - the common shaft member is mounted for movement relative to the frame between a weaving position and a leveling position in which the output conduit and the probe conduit are facing each other Contacted and fluidly connected, the output conduit and the probe conduit are remote from each other in the leveling position; - the machine further comprising a system for filtering the lubricant circuit, the filtration system The method includes: an upstream filter component that filters the lubricant before the lubricant of the lubricant circuit passes into the suction passage; and/or a downstream filter component that passes the lubricant to the lubricant circuit to The lubricant is subsequently filtered in the discharge passage; - the machine includes an input shaft member that drives the swinging rod movements and drives the pump to operate to cause the lubricant to Circulating between the primary conduit and the secondary conduit through the pump and through the pump; - the input shaft member traverses the pump body centrally; - the pump includes a pump body that can be fixed to the pump body according to two different orientations a reverse member, the two orientations comprising: wherein the pump drives the lubricant from the suction passage as far as the first orientation of one of the discharge passages when the input shaft member rotates in a first rotational direction; And the pump drives the lubricant from the suction passage as far as the second orientation of the discharge passage when the input shaft member rotates in a second rotation direction opposite to the first rotation direction; - the pump system a secondary cycloid type and including a complementary pumping component that drives the lubricant through the pump; - the reverse member includes a cover that is added to the pump body, the complementary pump components including an internal rotor and a An outer rotor rotatably mounted to the cover and the inner rotor is mounted for attachment to the shaft of the machine, the cover being designed to be mounted to the pump around the inner rotor in accordance with at least two different orientations On the main body, Defining two distinct positions of the outer rotor relative to the inner rotor, wherein the outer rotor is off-axis relative to the inner rotor; - the lubricant circuit includes a first continuous assembly of conduits, the conduits Formed in the frame for transporting the lubricant from the discharge passage as far as one of the distribution components of the lubricant supply conduit; - the lubricant circuit includes a second continuous assembly of conduits, the conduits being formed a system in the frame for transporting the lubricant from one of the lubricants circulating in the lubricant circuit for filtration as far as the suction channel; and - the suction channel coincides with the primary conduit, the discharge channel being The secondary conduits are coincident and the pump body is in a single piece with the frame. The subject matter of the present invention is also a knitting machine comprising a shed machine as previously defined herein, the shed machine forming a rotary dobby or a cam mechanism.

The shed machine 2 of Figures 1 and 2 is provided for integration into a knitting machine and the shed machine 2 is of the type of cam mechanism. The machine 2 includes an input shaft member 4 defining an axis X4 that is intended to be driven by a drive member of a knitting machine (not shown) to rotate about axis X4. The input shaft member 4 is supported by a frame 6 of the machine 2. Machine 2 also includes a drive shaft member 8 that is only visible in FIG. The shaft member 8 is also supported by the frame 6 and is driven by the input shaft member 4 to rotate about its own axis X8 and relative to the frame 6. The shaft member 4 and the shaft member 8 are perpendicular to each other, and the shaft member 4 includes one of the tapered pinion types, the drive wheel 10, and the drive wheel 10 and the shaft member 8 of the shaft member 8 are engaged with the receiving wheel 11. The machine 2 also includes a shaft member 12 having a particular axis X12 parallel to the X8 axis. For convenience, the description is oriented according to Figure 4. The terms "high" and "upper" refer to one of the orientations in the orientation of Figure 4, and the terms "low" and "lower" designate an opposite direction. The frame 6 forms a lower support in a slot shape and in this case includes a bottom portion 14 and a peripheral wall 56 projecting upwardly from the bottom portion 14. The machine 2 also includes a cover (not shown) that is removably mounted to the peripheral wall 56 of the frame 6 to enclose the frame 6 from the top. In this manner, the shaft member 4, the shaft member 8 and the shaft member 12 are included between the bottom portion 14 and the outer cover (not shown), which defines a space within one of the machines 2. One of the lubrication systems of the machine 2 described below moves the oil lubricant within this interior space. Thus, the frame 6 receives a specific amount of lubricant that fills at least a portion of the space within the machine 2. The machine 2 also includes a swinging lever 16 also referred to as an "output rod" that is rotatably mounted to the shaft member 12 independently of each other about the axis X12. Thus, the shaft member 12 forms a shaft member of the support rod 16 and is shared by the rods 16 for this purpose. To simplify the drawings, a single rod 16 is illustrated, the other rods being omitted. By way of example, the machine 2 comprises eight rods 16 mounted on the shaft member 12 and arranged alongside the shaft member 12 next to each other. In practice, the number of rods 16 mounted on the shaft member 12 can be adapted depending on the type of knitting machine and the pattern of the fabric to be woven on the loom, wherein the machine 2 is integrated into the knitting machine. The rods 16 each extend in a plane orthogonal to the axis X12 and are separated from the rolling elements by the axial abutment 18. Each of the abutments 18 is interposed between two rods, except for two of the side bars 16 of the group of adjacent links 16. In addition, each rod 16 includes a traverse housing (not shown) and extends to an extension 24 outside of the machine 2. The extension 24 is coupled to a mechanical element of a drawing system (not shown) to form a shed on the loom. Regarding the shaft member 8, it is equipped with a plurality of cams 20 (visible in FIG. 3) to drive the rod 16 to swing about the axis X12 via the rollers 22 rotatably mounted on the rod 16. In effect, each rod 16 includes two rollers 22 that each rotate about an axis X22 and are rotated relative to the associated rod 16. The plurality of axes X22 are parallel to each other and parallel to the axis X12. The rotating shaft member 4 thus drives the rod 16 to move. The frame 6 includes a first plate 26 and a second plate 28 via which the common shaft member 12 is supported on the frame 6. The plates 26 and 28 protrude from the bottom 14 of the frame 6 and away from each other and extend in respective planes P26 and P28 that are parallel to each other and perpendicular to the axis X12, as illustrated in FIG. Preferably, the plate 26 and the plate 28 are mounted to the bottom portion 14 by means of screws. Alternatively, at least one or both of the plates 26 and 28 are made of the same material as the bottom 14. One of the first portions 30 of the shaft member 12 extends from the first plate 26 as far as the second plate 28 and one of the second portions 32 of the shaft member 12 visible in FIG. 3 from the second plate 28 in a direction opposite the first plate 26 extend. A first end 34 of the shaft member 12 is received against the plate 26, and the first portion 30 of the shaft member 12 begins from the first end 34. The plate 26 includes a recess 38 for receiving the shaft member 12, the shaft member 12 being supported within the recess 38 via its first end 34, as seen in Figures 4, 6 and 7. The recess 38 has a U shape and includes a bottom portion 40 and two parallel edges 42 extending from the bottom portion 40. The edges 42 are positioned relative to each other at a distance greater than and near the diameter of the section defined at the end 34 of the shaft member 12. Regarding the bottom portion 40, it has an edge 42 that is elongated in a circular shape to fit the perimeter of the end 34. The recess 38 extends into the plane P26 and defines an axis X38 that is equidistant from the edge 42 and parallel to one of the edges 42 that is positioned obliquely relative to one of the planes defined by the bottom 14. The recess 38 is flared in one direction parallel to the central axis X38 and is directed upwardly opposite the bottom 40. In this manner, the shaft member 12 can be slid in the recess 38 from a low position (i.e., a so-called "weaving position" in which the shaft member 12 is supported against the bottom portion 40) until a high position (i.e., a so-called "school" The flat position in which the shaft member 12 is remote from the bottom 40 and the shaft member 8 and supports one of the abutting edges 42). One of the intermediate sections 36 of the shaft member 12 is supported on the plate 28. This intermediate section 36 is located between the first portion 30 and the second portion 32. Similar to the plate 26, the plate 28 includes a recess 44 for receiving a middle section 36 of the shaft member 12 that bears against the plate 28, the recess 44 having a bottom portion 46 and edges 48 that are parallel to each other and extend from the bottom portion 46, as in Figure 8. And can be seen in Figure 9. The recess 44 itself also has a U shape. The edges 48 are positioned relative to each other at a distance greater than or near the diameter of the section defined at the intermediate section 36 of the shaft member 12. Regarding the bottom portion 46, it has an edge 48 that is elongated in a circular shape to fit the perimeter of the intermediate section 36. The recess 44 extends into the plane P28 and defines an axis X44 that is equidistant from the edge 48 and parallel to the edge 48 and one of the axes X38. The recess 44 is flared in one direction parallel to the central axis X44 and is guided upwardly to oppose the bottom portion 46 and the shaft member 8. In this manner, the shaft member 12 can be slid in the recess 44 from the woven position (in which the shaft member 12 abuts against the bottom portion 46) as far as the leveling position (in which the shaft member 12 is remote from the bottom portion 46 and supported against Rely on one of the edges 48). In summary, the common shaft member 12 is mounted so as to be movable relative to the frame 6 between the weaving position and the leveling position while its axis X12 is parallel to the axis X8. The orientation of the shaft member 12 about its axis X12 relative to the frame 6 is also modified during positional changes corresponding to passage from one of the positions to the other, as will be described in more detail below. The machine 2 is therefore designed to have one of the weaving configurations (where the shaft member 12 is in the weaving position) illustrated in Figure 8 and one of the leveling configurations illustrated in Figure 9 (where the shaft member 12 is in a leveling) Moving between positions, the displacement of the shaft member 12 between the two distinct positions is performed by a leveling system (not shown) that engages the second portion 32 of the shaft member 12. In this leveling configuration, the roller 22 of each of the rods 16 is remote from the cam 20 such that the drive shaft member 8 is decoupled from the rod 16. In this leveling configuration, the rod 16 is therefore no longer driven by the shaft member 8, which is different from the braided configuration in which the roller 22 is supported on the cam 20 of the shaft member 8 and is driven by the cam 20. The plate 26 includes a bearing 50 and the plate 28 includes a bearing 52 via which the shaft member 8 is rotatably mounted on the frame 6 about its axis X8. The belt gear 11 is mounted on one end 51 of the shaft member 8, and the belt gear 11 extends behind the bearing 50 in the X4 axis direction, opposite to the bearing 52. The input shaft member 4 is rotatably mounted on the frame 6 and on one side 60 of the peripheral wall 56 via a third plate 54 about its axis X4. The third plate 54 extends in a plane P54 perpendicular to the planes P26 and P28. The third plate 54 projects from the bottom portion 14 and is traversed by the shaft member 4, and the shaft member 4 is mounted to the plate 54 via a bearing 58. For example, the plate 54 is mounted to the bottom portion 14 with screws, or another selection of the tie plate 54 is made of the same material as the bottom portion 14. The side 60 of the peripheral wall 56 extends in a plane parallel to the plane P54 and is located at a distance from the plane P54. The plate 54 is positioned between the side 60 and the side 62 of the wall 56, the side 62 being opposite the side 60 and being parallel to the side 60. The shaft member 4 is rotatably mounted through a bearing 64 through the side 60, and the bearing 64 is provided with a sealing member to prevent lubricant from leaking out of the space inside the machine 2. Thus, the shaft member 4 includes a first portion 66 that extends outside of the machine 2 and as far as the side 60; a second portion 68 that extends between the side 60 and the plate 54; and a third portion 70 that is A terminal portion extends from the plate 54 and drives the pinion 10 to be mounted and secured thereto. The lubrication system of the machine 2 includes a pump 72 that circulates lubricant in one of the lubricant circuits C2 of the machine 2 for use with one or several components to be lubricated (for example, the swinging rod 16) toward the machine 2. Distribute one of the components of the lubricant. The lubricant is then poured into the space inside the machine 2 for pumping again by the pump 72. The pump 72, which is only illustrated in Fig. 10, is a primary cycloidal hydraulic pump. The pump 72 is driven by the input shaft 4 to circulate the lubricant in the circuit C2 and in the machine 2. The pump 72 is traversed centrally through the second portion 68 of the shaft member 4 and is positioned between the plate 54 and the side 60 of the peripheral wall 56. In this case, the pump 72 includes a pump body 74 that is secured to the bottom 14 of the frame 6 (for example, by screwing to the bottom 14), as is apparent in FIG. The pump body 74 projects from the bottom 14 and is generally planar in shape to define a plane P74 that is parallel to the plane P54 and orthogonal to the axis X4. The shaft member 4 traverses the body 74 via a circular aperture 76 of the body 74 that is centered about an axis normal to the plane P74. The pump body 74 is further provided with a passage 78 for pumping lubricant and a discharge passage 80 for the lubricant. The passage 78 and the passage 80 lead to a suction port 84 and a discharge port 86 at an inner surface 82 of the pump body 74, respectively. The inner face 82 itself extends in a plane parallel to the plane P74, and the aperture 76 flares at the center of the inner face 82. Ports 84 and 86 each have an arcuate shape centered on the X4 axis and are positioned on either side of the aperture 76 opposite each other. Thus the discharge passage 80 is positioned on the side of the plate 26 and the plate 28, while the suction passage 78 is positioned on the opposite side. Suction channel 78 and discharge channel 80 also include a suction conduit 88 and a discharge conduit 90, respectively. The conduits 88 and 90 extend parallel to each other in a plane parallel to the plane P74. The conduit 88 connects the port 84 to one of the lower suction apertures 92 of the pump body 74. In the same manner, the discharge conduit 90 connects the port 86 to one of the lower discharge apertures 94 of the pump body 74. In summary, channel 78 is formed integrally with portions 84, 88 and 92, while channel 80 is formed integrally with portions 86, 90 and 94. The apertures 92 and apertures 94 lead to a lower face 96 of the pump body 74 that contacts the bottom 14 of the frame 6 when the pump body 74 is attached to the base 14 with screws. According to another alternative, not illustrated, one of the spacer members is interposed between the pump body 74 and the bottom portion 14, which is traversed by two conduits that extend the apertures 92 and apertures 94 toward the bottom portion 14. Pump 72 also includes an inner rotor 98 and an outer rotor 100 that form a movable pumping component in pump body 74. The inner rotor 98 is attached to the shaft member 4 and is traversed by the shaft member 4 via a central aperture 102 of the inner rotor 98. The central aperture 102 includes a flat portion 104 that cooperates with one of the flat portions 106 of the shaft member 4 to rotationally secure the inner rotor 98 about the axis X4 relative to the other shaft member 4. The rotor 98 is mounted against the inner face 82 of the pump body 74. The inner rotor 98 is provided with a plurality of outer teeth 108 (ten teeth 108 in this example) that are distributed around the outer circumference of the inner rotor 98 about the axis X4. The outer teeth 108 have a rounded contour. The outer rotor 100 forms a crown that fits around the inner rotor 98 against the inner face 82. The outer rotor 100 includes a central aperture 112 with internal teeth 110 projecting toward the center of the central aperture 112 and internal teeth 110 distributed about one of the axes of rotation X100 of the rotor 100. In this example, rotor 100 includes eleven teeth 110 having a rounded profile to generally fit one of outer teeth 108. In fact, the outer rotor 100 includes at least one additional tooth than the inner rotor 98 such that the outer teeth 108 engage the inner teeth 110. Therefore, the shaft member 4 drives the outer rotor 100 to rotate about the axis X100 via the inner rotor 98. The outer rotor 100 includes a circular peripheral surface 114 centered on the axis X100, through which the outer rotor 100 is mounted so as to be rotatable about the axis X100 on the cover 116 of the pump 72. The lid 116 is itself secured to the pump body 74 while being preferentially attached to the inner face 82 of the pump body 74 with screws. The cover 116 includes an internal cavity 117 centered on an axis X117 having a shape having a disk having a circular cross-section, the axis X117 being parallel with respect to the axis X4 and upwardly off-axis. The internal cavity 117 illustrated in Figure 10 includes a peripheral wall 119 for guiding the outer rotor 100 to rotate about the axis X117 such that the axis X100 is coaxial with X117 and is offset from an axis X76 defined by the aperture 76. axis. The axes X76, X100 and X117 are contained in the same plane which, when mounted in the machine 2, is orthogonal to the plane of the bottom 14, orthogonal to plane P74 and parallel to planes P26 and P28. Thus in this mounting configuration, the height of the axis X4 is between the axis X117 and the lower face 96. The inner cavity 117 is closed by the face 82 when the cover 116 is mounted to the pump body 74 such that the rotors 98 and 100 are received in the interior cavity 117 between the face 82 and the cover 116. The lid 116 further includes a circular aperture 118 that is coaxial with the aperture 76 of the pump body 74 when the cover 116 is mounted to the pump body 74 and that is received by the shaft member 4 via the circular aperture 118. A sealing gasket 120 is provided between the orifice 118 and the shaft member 4 to substantially sealably seal the internal chamber 117 from the pump 72. One of the same type of sealing gaskets may be provided within the orifice 76 as appropriate. The inner rotor 98 and the outer rotor 100 form a pumping component of the pump 72. The teeth 108 and the teeth 110 together form an annular bore defining one of the suction-discharge chambers of the lubricant, the volume of the suction-discharge chamber varying with the rotation of the rotor 98 and the rotor 100 controlled by the shaft member 4, the volume of which The change produces a suction at the suction port 84 leading into some of the chambers, the volume of the suction-discharge chamber increasing with the rotation of the shaft member 4, and leading to some of the chambers A discharge is produced at the inner discharge port 86, and the volume of the suction-discharge chamber decreases as the shaft member 4 rotates. A suction-discharge chamber is formed on the side of the axis X4 opposite the bottom portion 14 and connects the port 84 to the port 86. Thus, rotation of the shaft member 4 about its axis X4 in accordance with a first direction of rotation (a so-called "direct" rotation) causes lubricant to be pumped from the suction passage 78 as far as the discharge passage 80. The rotating teeth 108 and teeth 110 participate in the driving of the lubricant between the suction passage 78 and the discharge passage 80. Preferably, the cover 116 is designed to be mounted to the pump body 74 (not shown) around the inner rotor in accordance with at least one second orientation, which is different from the orientation previously described herein. In its second orientation, the cover 116 is preferentially rotated 180 degrees (degrees) about the axis X4 with respect to the first orientation illustrated in the figures such that the height of the axis X117 is between X4 and the bottom 14. In this case, a suction-discharge chamber is formed between the axis X4 and the bottom portion 14 while the port 84 is connected to the port 86. Rotation of the shaft member 4 about its axis X4 in accordance with a second direction of rotation (a so-called "indirect" rotation) opposite the first direction of direct rotation causes the lubricant to be pumped from the suction passage 78 as far as the discharge passage 80 . Thus, the pump 72 can be easily adapted to the direction of rotation of the shaft member 4 depending on the orientation of the cover 116 on the body 74. Thus, the two orientations of the cover 116 define two distinct positions of the outer rotor 100 relative to the inner rotor 98. The cover 116 forms a reverse member with its cavity 117 which can be easily configured to adapt the pump 72 to the circuit C2 between the passage 78 of the pump 72 and the passage 80, allowing the pump 72 to be adjusted to apply one of the lubricants appropriately The direction of circulation, that is to say towards the part to be lubricated, regardless of the direction of rotation of the shaft 4 of the drive pump 72. Another option is the other reverse member of the pump (such as a spacer interposed between the pump body 74 and the bottom 14 that gives the possibility of reversing the suction passage 78 and the connection of the discharge passage 80 to the circuit C2) It can be adapted to give the possibility of the lubricant selecting the direction of circulation within circuit C2. Alternatively, as an alternative to a cycloidal pump, the machine 2 can also be equipped with any pump that can be traversed by the input shaft member 4 and generated around the shaft member 4 to one of the annular chambers for suction-discharge. For example, a single pallet eccentric pump or a gear pump can be used as an alternative to the trochoid pump mentioned above. In still another option, the shaft member 8 can traverse the pump 72 and can alternately drive the pump 72 with the shaft member 4 (or any other shaft member belonging to the member for oscillating the drive rod 16). As a non-limiting example, when the rotational speed of the shaft member 4 is 900 rpm (revolutions per minute), the pump 72 is designed such that the lubricant is 6 l/m (liters per minute) in the circuit C2 of the machine 2. A flow rate cycle. Further, a lubricant distribution conduit 122 is formed inside the common shaft member 12 and extends coaxially with the axis X12, as will be apparent from FIGS. 1 and 2. A tubular wall 124 (having a section having an annular shape with a circular cross-section that belongs to the common shaft member 12) is peripherally bounded by the distribution conduit 122 and coaxial with the axis X12. Thus, the tubular wall 124 advantageously forms the wall of the conduit 122 and delimits an interior space in which the lubricant is intended to circulate. Thus, the shaft member 12 is a hollow tubular shaft member within which the lubricant circulates. The oscillating rod 16 is actually mounted to the tubular wall 124 about a tubular wall 124, for example, via a roller bearing having a roller (not illustrated). Lubricant dispensing orifice 126 is formed through tubular wall 124 along first portion 30 of shaft member 12 on which rod 16 is mounted. Accordingly, the dispensing conduit 122 communicates with the exterior of the common shaft member 12 such that the rod 16 is lubricated by the lubricant that escapes from the dispensing conduit 122 via the dispensing orifice 126 as it swings. In effect, the orifice 126 distributes the lubricant to the friction component on the exterior of the common shaft member, to the shaft abutment 18 and to the roller bearing (not shown, the rod 16 is mounted to the shaft member 12 via the roller bearing). Therefore, the shaft member 12 has both the function of supporting a common shaft member of the rod 16 and the function of one of the lubrication system distribution members. The distribution conduit 122 extends between a first upstream end 128 located adjacent the plane P26 of the first plate 26 and a second downstream end 132 located adjacent the plane P28 of the second plate 28. From the first end 128, the shaft member 12 includes a conduit extending radially with respect to the axis X12 while allowing the conduit 122 to extend, the conduit 130 leading only into the outer radial surface of the first end 34 of the shaft member 12, such as It can be seen in Figures 1 and 6. Thus, the supply of lubricant to the distribution conduit 122 is performed radially through the conduit 130 relative to the axis X12. An output conduit 134 extends the conduit 122 radially at the second end 132 relative to the axis X12. The output conduit 134 extends in a direction parallel to the direction of the supply conduit 130 and leads to the outer radial surface of the intermediate section 36 of the shaft member 12, as seen in Figures 8 and 9. Accordingly, the lubricant is intended to circulate from the supply conduit 130 in the dispensing conduit 122 as far as the dispensing orifice 126 and the outlet conduit 134. When the shaft member 12 is in the braided position, the supply conduit 130 is placed in face-to-face contact (preferably, a leak-proof contact) with one of the transfer conduits 136 formed in the first panel 26. In this case, the conduit 136 leads into the surface of the bottom 40 of the recess 38 and is coaxial with the axis X38. As seen in Figure 7, one of the openings 136A forming the opening of the conduit 136 is located on the bottom 40. Thus, in this weaving position, the transfer conduit 136 belonging to the lubricant circuit C2 provides lubricant to the distribution conduit 122 through the conduit 130. In the leveled position, contact between the transfer conduit 136 and the supply conduit 130 is interrupted to the extent that the shaft member 12 is remote from the bottom portion 40. Advantageously, in the leveling position, the rotation of the shaft member 4 and the shaft member 8 is interrupted, causing the pump 72 to stop. Furthermore, the pump 72, and in particular the discharge conduit 90 of the discharge passage 80, is connected to one of the secondary conduits 138 of the lubricant circuit C2. This secondary conduit 138 is formed in the bottom 14 of the frame 6 and connects one of the first portions 142 of the conduit 138 to one of the supply conduits 140 formed in the first plate 26, the supply conduit 140 itself being coupled to the conduit 130 for transmission through the first plate The transfer conduit 136 supplies the shaft member 12. The secondary conduit 138, the supply conduit 140 and the transfer conduit 136 thereby form a first continuous assembly of conduits formed in the frame 6 for transporting lubricant from the discharge passage 80 of the pump 72 as far as the dispensing member The supply conduit 130. In this case, the conduit 138 includes a first portion 142 that opens into the surface of the bottom portion 14 to face and contact the lower discharge aperture 94 of the discharge conduit 90 when the pump 72 is mounted on the frame 6 (preferably, one Anti-leakage contact). It should be understood that the aperture 94 leads directly into the first portion 142 of the conduit 138 without any intermediate connecting members. This first portion 142 is coaxial with the conduit 90 such that lubricant circulates from the conduit 90 as far as the first portion 142 of the conduit 138. The secondary conduit 138 includes a second portion 144 that is intermediate and extends the first portion 142 into the plane of the bottom portion 14 in a manner perpendicular to the first portion 142. The second portion 144 extends from the bottom of the pump 72 as far as below the first plate 26. The secondary conduit 138 finally includes a third portion 146 that extends the second portion 144 toward the outer casing of the machine 2 in a manner perpendicular to the second portion 144 and parallel to the first portion 142. The third portion 146 extends into the bottom portion 14 such that when the plate 26 is assembled to the bottom portion 14, the third portion 146 is in face-to-face (preferentially) anti-leakage contact with the input aperture of the supply conduit 140 of the plate 26. Go to the surface of the bottom 14 . The secondary conduit 138 thus forms a U, as can be seen in Figures 1 and 2. The supply conduit 140 is substantially linear and extends in a plane P26 perpendicular to the transfer conduit 136. In Fig. 2, the cut portion of the plate 26 where the conduit 136 and the conduit 140 are located is not visible in view of the perspective angle. It will be appreciated that mounting the pump 72 to the frame 6 and mounting the plate 26 to the bottom 14 will cause the discharge passage 80 of the pump 72 to communicate with the supply conduit 140. Thus, the pump 72 discharges the lubricant as far as the conduit 130 and conduit 122 and discharges from the conduit 130 and conduit 122 to the dispensing orifice 126 toward the swinging rod 16. A detection probe 148 (obvious in Figures 8 and 9) is provided for detecting the presence of lubricant in circuit C2. The probe 148 is mounted at the top of the second plate 28 so as to be placed downstream of the dispensing orifice 126 of the dispensing member in the circuit C2. The lubricant circuit C2 includes a probe conduit 150 formed in the second plate 28 in the plane P28 and connected to one of the probes 148. The probe conduit 150 forms, for example, a straight or curved conduit assembly that is fluidly connected to the loop C2. Preferentially, the probe conduit 150 forms a continuous portion of a linear conduit in which one of the auxiliary conduits 152 of the circuit C2 is included, the auxiliary conduit 152 being in face-to-face with the output conduit 134 when the shaft member 12 is in the braided position And placed in contact mode. The output conduit 134 of the shaft member 12 is coupled to the probe conduit 150 through an auxiliary conduit 152. The output conduit 134 is preferably coaxial with the axis X44 and leading into the surface of the bottom 46 of the recess 44 when the shaft member 12 is in the braided position. An orifice 152A forms an opening in the probe conduit 152 at the auxiliary conduit 152. Thus, in the braided position, the output conduit 134 belonging to the lubricant circuit C2 and supplied by the dispensing conduit 122 of the common shaft member 12 supplies lubricant to the probe conduit 150 through the auxiliary conduit 152. Setting the leveling position of the shaft member 12 causes the output conduit 134 and the auxiliary conduit 150 to move away from each other, as seen in FIG. As can be seen in Figure 9, in the leveled position, the output conduit 134 and, thus, the supply conduit 130 are oriented obliquely upward. In effect, the shaft member 2 moves not only along the axes X38 and X44 between the weaving position and the leveling position, but also about its axis X12 with respect to the frame 6 at an angle comprised between 0 and 90°. In the leveled position, pump 72 is stopped. The detection probe 148 includes a buoy 154 that is immersed in one of the lubricant grooves 156 formed in the plate 28. The buoy 154 is mounted for movement in a vertically translatable manner on one of the probes 158 of the probe 148. The sensor 158 can send an alarm signal to the machine when the oil level in the reservoir is below a predetermined threshold (ie, in a situation where the buoy 154 is in a predetermined position toward the bottom of the slot 156) 2 one control unit. Probe conduit 150 connects slot 156 of probe 148 to auxiliary conduit 152. The lubrication system also includes a pocket 160 located in the frame 6 for collecting lubricant. Lubricant enters the collection pocket 160 under the suction action of the pump 72 such that the lubricant is drawn into the pocket 160. A pocket 160 is formed in the bottom portion 14, preferably at the lowest point of the machine 2, so that all of the lubricant contained in the frame 6 can be collected. Machine 2 includes a system of lubricants for the filtration circuit that includes at least one upstream filter component 162 that is added to frame 6 to enable maintenance or easy replacement. In this case, the upstream filter member 162 is generally elongate in shape along one of the axes X162 and housed in a sheath 164 of the frame 6, the sheath 164 being raised from the bottom 14 in accordance with a tilt axis that is coaxial with the axis X162. Preferably, the filter member 162 is threaded into the sheath 164 through the lower end 171 of the sheath 164 such that one of the upper ends 170 of the member 162 can be accessed from the exterior of the frame 6 while traversing the peripheral wall 56 of the frame 6. Side 62. The lower end 171 is oriented toward the bottom 14 and the upper end 170 is in the opposite direction along one of the axes X162. A plug 172 for protecting the filter member 162 is screwed coaxially with the axis X162 to the sheath 164 at the upper end 170. The filter member 162 defines a conduit 166 coaxial with the axis X162 that extends from the collection pocket 160 as far as the high end of one of the permanent magnets 168 adjacent the filter member 162, the permanent magnet 168 itself being located at the upper end 170, below the plug 172 . Magnet 168 collects possible metal debris and debris contained in the lubricant. The filter member 162 further includes a tubular filter 174 or screen that is positioned about the conduit 166 and is intended to pass through the filter 174 by circulating the lubricant in an axial direction downwardly relative to the axis X162. The lubricant is filtered by an internal compartment 176 located in one of the loops positioned above the collection pocket 160. The inner compartment 176 extends over a portion of the circumference and height range of the tubular filter 174 such that lubricant is extracted radially from the tubular filter 174 to dump the lubricant into the interior compartment 176. Preferably, the collection pocket 160 and the inner compartment 176 are fabricated from the same material as the bottom portion 14. Another option is that they can form elements that are added to the bottom portion 14. The compartment 176 thus receives the lubricant after it has been filtered in the filter element 162 under the suction action from the pump 72. Filter element 162 filters the lubricant of circuit C2 before it passes into the pumping passage 78 of the pump. Alternatively, the machine 2 includes a downstream filter component that filters the lubricant after it passes through the discharge passage 80. This downstream filter component is thus connected to circuit C2 between pump 72 and distribution conduit 122, that is, for example, in series with secondary conduit 138. In this case, the upstream filter element 162 is optional. Finally, circuit C2 includes a primary conduit 178 that connects compartment 176 to a suction passage 78 of pump 72. A primary conduit 178 is formed in the bottom 14 of the frame 6 and includes a first substantially horizontal portion 180 extending from the compartment 176 along an axis parallel to the axis X4. The primary conduit 178 includes a second portion 182 that leads into the surface of the bottom portion 14 to face the suction aperture 92 below the suction conduit 88 of the pump 72 when the pump is mounted on the bottom portion 14 (preferably ) Anti-leakage contact. It should be understood that the aperture 92 leads directly into the second portion 182 of the conduit 178 without any intermediate connection members. Thus in this case, the second portion 182 is coaxial with the suction conduit 88 such that lubricant circulates from the second portion 182 as far as the conduit 88. Portion 180 of primary conduit 178 is perpendicular to portion 182. Lubricant circuit C2 thus includes a second continuous assembly of conduits formed in frame 6 for conveying lubricant from one of the systems for filtering lubricants to suction passage 78 of pump 72. In particular, this second assembly includes an interior compartment 176 and a primary conduit 178. The various conduits of circuit C2 of machine 2, for example, have a diameter of about 6 mm (mm). In summary, the lubricant circuit C2 in the order of lubricant flow includes: collection pocket 160, sheath 164, internal compartment 176, primary conduit 178, suction passage 78, lubricant suction-discharge chamber of pump 72, discharge passage 80 Secondary conduit 138, supply conduit 140, transfer conduit 136, supply conduit 130, distribution conduit 122, output conduit 134, auxiliary conduit 152, probe conduit 150, and slot 156. Thus, the circuit C2 is formed in the frame 6, the common shaft member 12 and the pump 72 such that the various components of the frame 6 (such as the bottom 14 and the plates 26 and 28), the various components of the filter member 162, the various components of the pump 72, and the shaft The various component connections of piece 12 connect all of the portions of circuit C2 together. Advantageously, it is not necessary to apply one of the additional elements of the flexible conduit type to form a loop, which simplifies the installation and maintenance of the machine 2. This defines a method for manufacturing the machine 2 in which the bottom 14, the plate 26 and the plate 28, and the pump body 74 are fabricated by molding and then by machining. The method of manufacture of machine 2 includes the steps for attaching pump body 74 and plate 26 and plate 28, for example by screws, to bottom portion 14, which forms loop C2. In this document, the reference to "connected" or "fluid link" or "fluid connection" means the presence of a fluid in one or several parts of a machine in a connected loop configuration that allows fluid to be in the machine. One way, one channel or one conduit is cycled between components or between two spaces. For example, the specific conduit of the frame 6 and the particular conduit of the pump 72, in particular the conduit formed with the straight portion, such as the primary conduit 178, the supply conduit 140, the transfer, are made by machining (specifically, by drilling) A conduit 136, an auxiliary conduit 152, a probe conduit 150, a suction conduit 88 or a discharge conduit 90. For example, the suction port 84 and the discharge port 90 are made by milling the pump body 74, and the billet of the pump body 74 is previously produced by molding. Others may be made during the step of one of the relevant parts for molding the frame 6 by means of a recessed metal core or insert introduced into the moulding of the relevant part, in particular the moulding used to form the bottom 14 A conduit, such as a secondary conduit 138. Depending on the situation, circuit C2 includes a lubricant conduit (not shown) for lubricating the engagement of drive wheel 10 and receiving wheel 11. Depending on the case, a sealing gasket is provided to prevent leakage of the connection by contact between the two elements of circuit C2 of machine 2. For example, each of the apertures 90 and the apertures 92 is provided with a receiving counterbore or a flat joint formed at the surface of the lower surface 96 for one of the O-ring gasket types, not Graphical illustration. The machine 2 series cam mechanism type previously described herein. As an alternative, the lubrication system can be integrated on a rotary multi-arm type one of the shed machines, wherein substantially the shaft member 8 with the cam 20 is replaced by a spindle member equipped with an eccentric actuation element, the spindle member It belongs to a drive unit for driving a swinging lever 16 mounted on a common shaft member parallel to one of the main shaft members, the actuating member being connected to the rod 16 by a connecting rod body. In this rotary dobby, the components for dispensing the lubricant are made of the same material as the frame or added to the frame. The dispensing member is fluidly coupled to the discharge passage of the pump and is capable of supplying at least one lubricant conduit formed in the frame and the additional plate and leading to the component to be lubricated to the machine designed to move. The awaiting lubrication component is, for example, a tapered snap drive component, a transducer of the spindle member, a common shaft member on which the output rod is mounted, a friction zone of the output rod, or any other mechanical chain requiring a lubricant supply. road. According to another alternative, the lubrication system can be integrated into one of the mechanical types of cams, the common shaft of the hopper machine being leveled by the eccentric element, as exemplified in FR-A-2 868 090 in. According to another alternative not shown, the first plate 26 is axially fluidly coupled to the dispensing conduit 122 of the common shaft member 12 at the end of the shaft member and axially relative to the axis X12 such that in the weaving position of the machine, the transfer The conduit 136 coaxially supplies the dispensing conduit 122 of the common shaft member 12 through an orifice disposed facing the dispensing conduit 122. According to another alternative, the second plate 28 is axially fluidly coupled to the dispensing conduit 122 of the common shaft member 12 at the end of the shaft member and relative to the axis X12 such that in the weaving position of the machine, the dispensing conduit 122 is permeable. An orifice of one of the axes of the conduit is dispensed to supply the auxiliary conduit 152 coaxially. Alternatively, the transfer conduit 136 and the auxiliary conduit 152 can be fluidly coupled to the distribution conduit 122 of the shaft member 12 via intermediate components added to the first plate 26 and the second 28 plate, respectively. Alternatively, the pump body 74 is made of the same material as the bottom 14 such that the pump body 74 is integrated into the frame 6. According to this alternative, the suction passage 78 of the pump body coincides with the second portion 182 of the primary conduit 178. Additionally, the discharge passage 80 coincides with the first portion 142 of the secondary conduit 138. Whether the machine 2 of the present invention is a dobby or a cam mechanism or any other type of hopper machine, advantageously, a suction and discharge conduit, not shown, is formed in the frame 6 for connecting the lubricant circuit C2 to A system that cools one of the lubricants added to the machine. The various embodiments and alternatives set forth above may be combined to form a novel embodiment.
