Definitions

  • the present invention relates to a fixing device for fixing toothed elements to a component of a textile machine, in particular to a top comb, a circular comb, or a card flat, including a stationary bearing surface for the toothed elements and a flexible spring leg for pressing the toothed elements to the bearing surface by way of a holding force.
  • the toothed elements on combs and card flats can be of various designs.
  • the toothed elements can, for example, include needles.
  • the toothed elements can just as well be designed as stamped parts, which include one or a number of teeth.
  • the toothed elements can be fixed to a supporting body by plastic deformation of a holding part or of a part of the supporting body. It can hereby occur that the material of the holding part is not deformed only plastically but also elastically, and that the elastic deformation recedes after the actual fixing process. The toothed elements are then not held securely by a holding force and can become loose again.
  • German published patent application DE 36 24 292 A1 in which a fixing device for sawtooth punched parts of the above mentioned type are provided. At least one flexible spring leg is provided which fixes the sawtooth punched parts with a defined holding force to the supporting body. The holding force acts continuously on the sawtooth elements so that they are prevented from becoming loose.
  • the spring leg is elastically deformed when applied to the sawtooth punched parts or to the supporting body. It is therefore necessary to overcome the holding force acting from the start when the sawtooth punched parts are applied.
  • a number of toothed elements must be fixed to the component.
  • a large number of sawtooth elements are arranged in close proximity to one another.
  • the sawtooth elements must hereby be slid traversely to the working direction along the stationary bearing surface and along the elastic spring leg and mounted onto the supporting body.
  • a relative strong sliding force is necessary in the case of the known arrangement, as the holding force of the spring leg is effective directly at the start of the application of the toothed element.
  • each toothed element When the toothed elements are being replaced, each toothed element must be removed from the supporting body using a relatively high force while overcoming the holding force. Mounting and replacing the toothed elements is thus complex.
  • This object has been achieved in accordance with the present invention in that a device for neutralizing the holding force of the spring leg is provided.
  • a fixing device for toothed elements having a device for neutralizing the holding force of the spring leg has the advantage in that the holding force of the flexible spring leg can be deactivated during the mounting of the toothed element, thus providing that the adjacently mounted toothed elements can slide along the stationary bearing surface without meeting any resistance.
  • Mounting the toothed elements in the take-up element is hereby simplified to a great extent. It ensures that the toothed elements are arranged adjacently without any intermediary spacing.
  • the device for neutralizing the holding force is deactivated, so that the spring leg presses the toothed elements to the bearing surface and fixes the toothed elements securely by use of its holding force. Further fixing elements for the toothed elements are not necessary.
  • the device for neutralizing the holding force deactivates the holding force of all toothed elements arranged adjacently in one row simultaneously.
  • the device for neutralizing the holding force has advantages. Not all the toothed elements have to be removed individually from their take-up, as is the case in prior art. Subsequent to activating the device for neutralizing the holding force, no holding force of the spring leg whatsoever acts on the toothed elements. The toothed elements fall out of their take-up by themselves and can be easily disposed of.
  • a fixing device is particularly advantageous for application in a top comb or a circular comb for a combing machine.
  • a fixing device can also be applied in a very advantageous way for the fixing of the toothed elements to a card flat of a flat card.
  • the protective rights should also extend to a top comb, a circular comb and a card flat.
  • the device for neutralizing the holding force is blockable against unintentional opening.
  • the device for neutralizing the holding force is locked subsequent to the mounting of the toothed elements in the component, the device for neutralizing the holding force is prevented from being unintentionally opened during transport and during the application of the component in the textile machine. Unintentional activating of the device for neutralizing the holding force can result in the toothed elements falling irretrievably out of their take-up. As a result of the blocking of the device for neutralizing the holding force, the holding force of the spring leg can also advantageously be increased.
  • the stationary supporting surface and the spring leg are integrated in one piece in a supporting body for the toothed elements.
  • the supporting body can, for example, be subsequently fixed to a circular comb.
  • the supporting body is formed, for example, directly by the head area of the blade of a top comb.
  • the take-up for the toothed elements formed by the stationary bearing surface and the spring leg is integrated in a supporting body of the component of the textile machine.
  • This embodiment is particularly advantageous when the basic material of the supporting body is made of a sufficiently flexible material, for example aluminum. If the supporting body is made of a less flexible material, it can also be advantageous to design the spring leg as a separate component and to fix it to the supporting body.
  • the spring leg can, for example, be made of spring steel and can exert a relatively strong holding force on the toothed elements.
  • the supporting body includes a recess assigned to the spring leg, which recess can be closed by way of a bar adapted to the form of the recess for the purposes of blocking the device for neutralizing the holding force of the spring leg.
  • the bar adapted to the form of the recess can be applied to the recess of the supporting body.
  • the device for neutralizing the holding force is blocked and the holding force of the spring leg can no longer be released. Only when the bar is removed is the holding force of the spring leg releasable again.
  • the device for neutralizing the holding force is formed by a lever arm connected with the spring leg for relieving the pressure of the spring leg.
  • the lever arm for relieving the pressure can be formed advantageously in one piece with the spring leg.
  • the device for neutralizing the holding force includes at least one take-up surface on the spring leg for an auxiliary tool for relieving the pressure of the spring leg.
  • the auxiliary tool is applied to the spring leg and the spring leg opened.
  • FIG. 1 is an enlarged side view of a schematically shown top comb including a fixing device according to an embodiment of the present invention.
  • FIG. 2 is a view according to FIG. 1 of another embodiment of the fixing device according to the present invention.
  • FIG. 1 To exemplify a component 2 of a textile machine including toothed elements 1 , a top comb for a combing machine is shown in FIG. 1 .
  • the top comb 2 includes essentially a blade 3 , a fixing device 4 for the toothed elements 1 , and the toothed elements 1 themselves.
  • the top comb 2 is assembled in the combing machine in such a way that the toothed elements 1 comb through a fiber material consisting of staple fibers in working direction A.
  • the actual dimension of the blade 3 as seen in working direction A lies in the range of several millimeters in thickness and, vertical to the drawing plane of FIG. 1 , in the range of several hundred millimeters in width.
  • the head of the blade 3 forms a supporting body 5 for the toothed elements 1 .
  • the toothed elements 1 consist of punched out parts or needles, which sit with their base end 6 in a take-up 7 of the supporting body 5 .
  • the toothed elements 1 are held in the take-up 7 by the fixing device 4 .
  • the fixing device 4 includes a stationary supporting surface 8 for the toothed elements 1 and a flexible spring leg 9 for pressing the toothed elements 1 to the supporting surface 8 with a holding force B. In the position shown in FIG. 1 , the spring leg 9 is already pre-loaded and presses against the toothed elements 1 with the holding force B.
  • the fixing device 4 includes a device 10 for neutralizing the holding force of the spring leg 9 .
  • the device 10 for neutralizing the holding force is formed by a lever arm 11 connected with the spring leg 9 for relieving the pressure of the spring leg 9 .
  • the blade 3 of the top comb 2 can include a drawn profile made of a light metal, for example aluminum.
  • the spring leg 9 , the stationary supporting surface 8 and the lever arm 11 are integrated in one piece in the supporting body 5 or in the blade 3 .
  • the supporting body 5 includes a recess 12 assigned to the spring leg 9 .
  • the recess 12 gives rise to a virtual swivel axis 13 , which is formed in the supporting body 5 , and around which the spring leg 9 is swivel-mounted.
  • the device 10 for neutralizing the holding force is activated in that the lever arm 11 is loaded with a releasing force C, which causes the spring leg 9 to swivel in the direction of the arrow D around the swivel axis 13 and to release the toothed elements 1 .
  • the holding force B of the spring leg 9 is suspended and the toothed elements automatically fall out of the take-up 7 .
  • New toothed elements 1 can be mounted to the take-up 7 very easily.
  • the mounted toothed elements are initially placed in a non-fixed position while being closely adjacent to one another. When all the toothed elements 1 are mounted over the entire working width of the top comb 2 , the actuation of the device 10 is released.
  • the force C is removed from the lever arm 11 and the spring leg 9 swivels back in the opposite direction of the arrow direction D and exerts its holding force B on the toothed elements 1 .
  • the toothed elements 1 are thus held securely in the supporting body 5 of the top comb 2 . No further fixing elements are necessary.
  • the device 10 for neutralizing the holding force can be blocked subsequent to the mounting of the toothed elements 1 .
  • a bar (not shown) can be provided, whose outer contour is adapted to the form of the recess 12 .
  • the bar can be slid transversely to the working direction A into the recess 12 .
  • the spring leg 9 cannot be swiveled around the virtual swivel axis 13 in direction D.
  • it can be sufficient that the bar does not extend over the entire working width of the top comb 2 and that the recess 12 is blocked only in the outer areas of the supporting body 5 . It can be advantageous that the dimensions of the bar are so chosen that the bar can be pressed into the recess 12 using light pressure.
  • the holding force B of the spring leg 9 can hereby be increased.
  • FIG. 2 a top comb 2 is shown which has a somewhat differently designed device 20 for neutralizing the holding force on the fixing device 4 for the toothed elements 1 .
  • the same reference numbers denote the same parts as in FIG. 1 so that a repeat description can be omitted at this point.
  • the spring leg 9 is integrated into the supporting body 5 and can move around the virtual swivel axis 13 due to the recess 12 . In the position shown, the spring leg 9 is pre-loaded and presses the toothed elements 1 with the holding force B against the stationary bearing surface 8 .
  • the device 20 for neutralizing the holding force of the spring leg 9 can be activated for the purposes of mounting and disassembly.
  • the device 20 for neutralizing the holding force includes a take-up surface 21 , which is applied to the spring leg 9 in the form of a groove.
  • An auxiliary tool 22 for relieving the pressure of the spring leg 9 is provided, which takes the form of a rod extending over the entire width of the top comb 2 , the rod having a working surface 23 assignable to the take-up surface 21 .
  • the working surface 23 engages, in the form of at least one shoulder, with the groove formed by the take-up surface 21 .
  • a lever arm 24 is arranged on the side of the auxiliary tool 22 facing away from the working surface 23 , on which lever arm 24 a releasing force C can be exerted.
  • the device 20 for neutralizing the holding force in FIG. 2 can also be blocked by closing the recess 12 by use of a bar (not shown) adapted to the form of the recess 12 , so that the spring leg 9 cannot be swiveled in the direction of the arrow D around the swivel axis 13 .
