Definitions

  • the present invention relates to a supporting and loading arm for the drawing mechanism of a spinning machine which is provided with centrally supported pressure rolls and a U-shaped guide rail in which a guide bracket for each pressure roll is adjustably mounted in the longitudinal direction of the guide rail and adapted to be locked in the adjusted position, and which bracket engages with the lateral sides of the guide rail and is provided in its end with a guide recess for receiving pressure roll and with .a spring for exerting the required pressure upon the pressure roll.
  • each housing in the supporting arm and the guiding of the bearing member in the housing could be improved only by enlarging the housing and bearing member both vertically and in length. This is, however, impossible because it would then no longer be possible to adjust the pressure rolls to the small distances between them which :are required in such drawing mechanisms.
  • the invention provides that these arms are downwardly inclined so that the adjacent bracket arms when located close to each other will overlap each other like roof shingles.
  • the bracket arms are then preferably laterally guided in the U-shaped guide rail along a length, as seen in the direction of the drawing plane, which is .at least 1.3 times as long as the smallest possible distance between two adjacent pressure rolls on guide brackets of equal length.
  • a guide bracket of a very suitable and simple shape which takes up very little space may be attained by making it of sheet steel and by making its downwardly inclined part of a U -shaped cross section so as to form two lateral arms, and by mounting the leaf spring so as to extend substantially between these arms.
  • the leaf spring is designed so as first to follow the general oblique direction of the bracket arm, and its extension then presses directly or indirectly upon the shaft of the pressure roll.
  • the leaf spring may be suspended so as to have a three-point support. Two of these points are formed by abutments which are located near the secured end of the guide bracket and at least one of which is vertically adjustable,
  • the adjustable abutment may be formed by a setscrew which is adjustable from above. Another feature of the invention is to render this adjustable setscrew foolproof by providing it with a special cover which hides it and thus prevents it from being turned by an unauthorized person who is not familiar with the device. This cover is loosely held in position near one end by the bolt which secures the associated guide bracket to the U-shaped guide rail, while its other end is provided with a small projection which engages into a slot of the guide rail.
  • the setscrew can be reached only by bending the slightly resilient cover up wardly to lift the projection out of the slot in the guide rail and by then turning the cover toward one side about the bolt.
  • a cover may in addition be provided with a suitable marking for indicating the position of the guide bracket and for facilitating an accurate adjustment of this position relative to the guide rail.
  • the marking on the cover may for this purpose be associated with a scale which is marked on the guide rail.
  • the arms of the guide brackets of the supporting and loading arm according to the invention may extend either in the direction toward the first or feed roll or toward the last or delivery roll.
  • the obliquely inclined shape of the bracket arms according to the invention not only permits these arms to be mounted so as to overlap each other so that the adjacent pressure rolls may be spaced at a very small distance from each other but it also permits the adjacent pressure rolls to be spaced at a very large distance from each other by mounting the adjacent brackets so that their arms extend in opposite directions. It is thus possible to employ relatively short supporting and loading arms and still to attain a very large distance between the adjacent pressure rolls.
  • This arrangement has the further advantage that a large free area is attained on the lateral walls of the guide rail underneath and between two adjacent bracket arms which extend in opposite directions.
  • This area may be employed for mounting additional supporting or guide elements for further parts of the drawing mechanism which may consist, for example, of self-loaded rolls as employed especially for treating materials of a long staple length, or of clearer rolls or similar devices or of belts.
  • additional supporting or guide elements for such further parts of the drawing mechanism may also be provided directly on the arms of the guide brackets.
  • the locking spring which prevents the pressure roll from falling out of the guide recess in the end of the bracket arm when the supporting and loading arm is pivoted upwardly to the inoperative position is preferably mounted on the bracket arm, especially if the latter is made of sheet steel, by providing both side walls of the U-shaped bracket arm near the recessed end with tabs which are bent at a right angle to the surfaces of these side walls and which permits the locking spring to be securely hooked thereon in a very simple manner.
  • the locking spring may then also serve additionally as a means for mounting the clearer roll.

  • FIGURE 11 shows a top view of a part of the supporting arm according to FIGURE 10; while FIGURE 12 shows a diagrammatic side view of a sup.- porting arm according to a further modification of the invention which .is provided with three guide brackets, two of which are mounted so as to extend in opposite directions to each other.
  • the guide rail 1 has a U-shaped cross section and carries the guide brackets 3 which are made by being cast or molded and are secured to guide rail 1 by bolts 2 and nuts 2 so as to be adjustable in the longitudinal direction of guide rail 1.
  • the free ends of the oblique arms .4 of brackets 3 are provided with guide recesses 5, the side walls of which extend substantially vertically to the drawing plane EE. In these recesses 5 the bearing members 6 are guided which hold the shafts 7 of the twin pressure rolls 8, 8'.
  • Each shaft 7 is pressed in a downward direction by a leaf spring 9 which is likewise secured by the bolt 2 and nut 2 to the guide bracket 3, and extends substantially in the direction of the arm 4 of bracket and presses with its free end upon the bearing member 6 and through the latter upon shaft 7.
  • Guide rail 1 forms in the conventional manner a part of a supporting and load arm which is pivotably mounted at one end, not shown, on a supporting rod. When in the operative positron, this supporting arm is held in a certain location relative to the drawing plane E-E in which the leaf springs 9 press the pressure rolls 8, 8' with a certain pressure upon the lower rolls 10.
  • leaf springs 9 press the pressure rolls 8, 8' through the bearing members 6 so far downwardly in the guide recesses 5 until they engage upon the stop pins 201 which are mounted on the arms 4.
  • the bearing members 6 are then prevented by locking springs 202 from falling out of the guide recesses 5.
  • Each of these locking springs 202 is secured to the associated leaf spring 9 and extends between the two wall portions 5' and 5" which define each guide recess 5, and the free end 202'of this spring 202 forms a book which projects underneath the bearing member 6.
  • Each of the pressure rolls 8, 8" can therefore be removed from or reinserted into the associated bearing member 6 only when the supporting and load arm is pivoted upwardly and when the free end 202' of locking spring 202 is pulled back.
  • the width of leaf spring 9 decreases toward its free end which presses upon the pressure roller shaft so as to permit this end to be inserted between the walls 5, 5" of the guide recess 5 and to engage upon the bearing member 6.
  • FIGURE 3 shows the manner in which the bearing member 6 is held in the guide recess 5 and that the shaft 7 of the pressure rolls is held for a considerable length in the bearing member 6.
  • Guide bracket 3 is guided by the lateral surfaces 3' of its upper part along the side walls 1', 1" of guide rail 1 and also by the lateral surfaces 5" of the end of the bracket containing the guide recess. It is therefore guided along the greatest part of its length which insures that the accurate position of each guide bracket in :the guide rail and thus also the accurate position of each pressure roll 8, 8 parallel to the axis of the associated lower roll 10 will be maintained at all times.
  • the adjacent guide brackets very closely to each other so that the adjacent pressure rolls may also be located at a very short distance from each other.
  • the inclined arms of the adjacent guide brackets then overlap each other like the shingles on a roof.
  • the supporting arm as illustrated in FIGURE 4 comprises a guide rail 41 in which a pair of guide brackets 43 consisting of sheet steel are secured by bolts 42 and nuts 42 so as to be adjustable in the longitudinal direction of the guide rail.
  • the downwardly inclined bracket arms 44 and 44" are bent so as to have a U-shaped cross section, as shown in FIGURES 6 and 7, and are provided with guide recesses 45 in their free ends.
  • the wall surfaces 45 and 45" of these guide recesses may be easily made so as to be in accurate alignment with each other so that the shaft 47 of the respective pressure roll 48 and thus the pressure roll itself will extend exactly at right angles to the long bracket arms 44' and 44 and the pressure roll will extend exactly parallel to the associated lower roll.
  • each leaf spring 49 is pivotably mounted at its upper end on a pivot pin 403 at a short distance from bolt 42, and during the operation of the drawing mechanism the leaf spring engages with a setscrew 404 which is screwed through the nut 42' and projects through the slot 41 in the guide rail and through a bore in the cover 405.
  • This cover 405 serves as a washer for the bolt 42 and also covers a considerable part of slot 41, as shown in FIGURE 5.
  • One of its edges 405' or 405" or 405" serves as a marking for indicating and adjusting the position of the guide bracket and thus the position of the associated upper roll relative to the guide rail 41 in the direction of the drawing plane.
  • Guide rail 41 is for this purpose provided with a scale 41".
  • Setscrew 404 as well as bolt 42 are accessible from above when the cover 406 of the supporting arm which covers the guide rail is removed.
  • Cover 406 may also form a part of a locking or relieving lever, not shown, or be adjustably or removably connected thereto.
  • Setscrew 404 has a cylindrical end 404 which only engages at one point of its outer edge upon the leaf spring which extends obliquely to the setscrew. This prevents an accidental turning the screw and therefore renders a check nut unnecessary, even though the screw is only held by a few turns of its screw thread in the nut 42.
  • the lowerend of leaf spring 49 is bent over and the bent end 49' acts directly upon the shaft 47 of the pressure roll. Such a leaf spring may be completely inserted between the arms 44' and 44" and has a great effective length.
  • bracket 43 Since the U-shaped guide rail 41 and also the two arms 44' and 44" of each bracket 43 can be economically produced only with a certain tolerance in the inner width between the lateral sides 41" and 41" of the guide rail and in the outer distance between the two arms of the bracket, it is necessary to select a slide member which fits accurately between the sides 41" and 41"" of the guide rail. An accurate guiding of bracket 43 will, however, also be attained in a simple manner if prior to its installation its arms 44' and 44" are slightly spread, as indicated in an exaggerated manner in FIGURE 7. When installed, these arms 44 and 44" press lightly against the sides 41" and 41"" of the guide rail so that the bracket will fit without play into the guide rail but will still be easily slidable along the same.
  • Locking spring 402 and 402 for the pressure rolls 48 are slipped from above over the bent-over parts 45" on the arms 44 and 44" which are substantially in alignment with and closely adjacent to the guide recess 45 (also see FIGURE 7), and they are thus securely connected to these arms.
  • Locking spring 402' is bent over so as to be slightly wider than spring 402, and it also clamps a holder 408 for a clearer roll (not shown) upon the bent-over parts 45".
  • the guide brackets 83 which are guided in the guide rail 81 are also made of sheet steel similar to the brackets according to FIGURE 4 and are bent to a U shape to have a pair of arms 81' and 81".
  • the upper part 84' of each arm of each bracket extends obliquely downwardly in one direction, while its lower part 84" extends obliquely in the opposite direction and is provided at its free end with the guide recess 85 for holding an upper roll.
  • a guide bracket of such an elbow shape is advisable if these arms should not only be as long as possible so as to be safely guided, but if the point of securement of the upper part of the bracket should also be located at a very short distance from the axis of the associated upper roll, as seen in the direction parallel to the drawing plane.
  • This distance which is indicated in FIGURE 8 by the double arrow a is much shorter than the corresponding distance a in FIGURE 4 in which the side walls of the brackets do not have any angular shape.
  • Leaf springs 89 are made of a shape in accordance with the arms 84, 84" and their lower, substantially horizontal ends engage directly upon the shafts 87 of the pressure rolls. Due to their length, these leaf springs have a very suitable spring action.
  • the arm 85" at one side of the guide recess is provided with a covering 85 of plastic with good sliding properties, for example, nylon, so .as to insure that the shaft of the pressure roll which in operation is pressed against this side will slide easily thereon.
  • This covering 85" may be molded upon the arm 85" in the manner as indicated in FIGURE 8, or it may be removably secured thereto to permit it to be exchanged when worn.
  • the two arms 84' and 84" of the guide bracket do not engage continuously with the sides 81, 81" of guide rail 81, but only at their central and lower parts by means of outwardly pressed surfaces 107 and 108.
  • each guide bracket is securely guided on the guide rail even though the largest part of its lateral surfaces does not engage with the guide rail.
  • Each supporting arm according to FIGURE 8 likewise is provided with a setscrew 804 which is accessible from above and acts similarly as in FIGURE 4 upon the leaf spring, and it is also provided with a stop pin 801 for the leaf spring.
  • FIGURE 10 shows another modification of the invention in which the guide rail 101 again carries a pair of guide brackets 103 which are made of sheet steel and are adjustable on the guide rail in the longitudinal direction thereof.
  • Each bracket is securely clamped in a fixed position by a bolt 102 and a nut in the .form of a plate 102' into which the setscrew 114 is also screwed which acts upon the leaf spring 109.
  • the second abutment for the leaf spring consists of a downwardly bent lug 119 on the transverse part 103 of bracket 103 which has an aperture 119' with a small tab 119" projecting upwardly from the lower side of this aperture, as clearly shown in FIGURE 10a.
  • This tab 119 engages into an aperture 109' in the end of leaf spring 109 and thus holds the spring securely hooked thereon.
  • the other free end of the leaf spring is again bent back and presses directly upon the shaft 107 of the pressure roll which is guided within the recess 105 in the lower end of the arm of bracket 103.
  • the tapped plate 102' is further provided with a long tapped bore into which a setscrew 114 is tightly fitted which extends substantially vertically to the main part of leaf spring 109.
  • Setscrew 114 is accessible from above through the slot 101 in the guide rail and through a bore in the part 103' of the bracket, but only'when the cover 115 is turned toward one side.
  • This cover 115 is only loosely held in position by bolt 102 since the washer 102" lies on a disk 102" which centers the cover 115 and is slightly thicker than cover 115.
  • the cover 115 On its end, the cover 115 has a small projection which engages into the slot 101' and guides the cover therein. If this resilient cover is slightly lifted, for example, by a screw driver, at the end carrying the projection 115, it may then be turned toward one side even though the bolt 102 has not been loosened. The pressure which is exerted by the leaf spring upon the pressure roll may therefore be adjusted even though the guide bracket is rigidly secured to the guide rail.
  • cover 115 is provided with a marking notch 115" which is associated with a scale 101" on the guide rail for indicating and adjusting the position of the guide bracket relative to the guide rail.
  • the two guide brackets 103 according to FIGURE 10 are shown very closely adjacent to each other in the position in which the pressure rolls 108 and 108' are almost as close to each other as possible. If one of the brackets is reversed so that its arm extends obliquely downwardly in the opposite direction, as indicated in FIGURE 10 in dot-and-dash lines by reference numeral 103", the pressure rolls 108 and 108' will be spaced at a very great distance from each other, even though the two brackets are clamped on the guide rail very closely adjacent to each other. Underneath and between the arms of the adjacent brackets 103 ad 103" a large free area will then be formed on the lateral sides of the guide rail within which additional elements of the drawing mechanism may be mounted.
  • a holder 120 for supporting a slip or clearer roll is held by a slot or a projection 120' on these surfaces of the guide rail.
  • the guide rail is provided with further slots or projections 120" and 120' to permit the holder 120 to be mounted at different positions or several holders to be mounted adjacent to each other.
  • FIGURE 12 shows a complete supporting arm in which, for example, three guide brackets 123, 123', 123" are mounted in a manner so that the pressure rolls will be spaced at the greatest possible distances from each other.
  • a belt guide is provided in the main drawing area.
  • the guide bracket 123 which projects from the guide rail is made of sheet steel and its arm is of a U-shaped cross section, its open side is closed by acover 130.
  • the supporting arm is further provided within the area underneath the arms of the guide brackets 123 and 123' with a slide member which is connected to the guide rail and presses a belt upon its support. Furthermore, a roller 131 is supported on the arm of the bracket 123 for tightening the belt.
  • the pressure rolls may, if desired, be adjusted so as to be spaced at very short distances from each other.
  • the supporting means for the other elements 130', 131, etc. of the drawing mechanism may be removed in a very simple manner from the guide rail or the guide brackets.
  • a supporting and loading arm for the drawing mechanism of a spinning machine comprising an elongated guide rail having an inverted U-shaped cross section with an upper central web and a pair of spaced, substantially parallel lateral webs, a plurality of guide brackets each having an upper connecting part slidably adjustable along said central web and an arm extending obliquely downwardly from said connecting part between said lateral webs and having a free lower end projecting downwardly beyond the lower edges of said lateral webs, each said bracket engaging with and guided by said lateral webs at least near the lower edges thereof, said projecting lower end of each said bracket arm having a downwardly open guide recess therein with parallel side walls extending transverse and substantially vertically to said guide rail, a plurality of twin pressure roll units, each having a shaft centrally between its rolls and inserted into each said guide:
  • bracket arm between said lateral Webs of said guide rail and pressing with its other end from above upon the roller unit shaft carried by the bracket arm, and means for locking said brackets to said guide rail in different positions longitudinally thereof.
  • each said leaf spring is freely suspended on said connecting part and has three supporting points, two of said points forming abutments on said connecting part, means for adjusting at least one of said abutments in .a substantially vertical direction, and the third point formed by the engagement of the free end of said leaf spring with said shaft of said pressure roll unit.
