Definitions

  • the present invention relates to an apparatus for guiding strip stock and the like. 1
  • the apparatus for guiding such strips generally consist of rollers or sliding jaws which are usually adjustable in a direction transverse to the axis of the strip in accordance with the nominal width of the strip by means of screw spindles or the like. It is a well-known fact that, if the strip which is being fed varies in width, there is either considerable play between these guiding means and the edges of the strip or the guiding means will exe'r't too great a pressure upon these edges.
  • the guiding means for one or both edges of the strip are usually resiliently mounted. The result is then either a varying pressure upon the edges of the strip, for example, if the guiding means are acted upon by springs, or a constant pressure, for example, if
  • the guiding means are acted upon by hydraulic or pneumatic cylinders. This pressure upon the edges of the strip may also be adjusted in accordance with the dimensions and the type of material of the strip.
  • the known guiding means therefore do not permit untrimmed strips which have the usual manufacturing tolerances amounting, for example, to approximately 1% of the nominal width of the strip, to be guided in such a manner that there will always be a constant light guiding pressure upon the edges of the strip and that a sufiicient force will also be exerted upon the strip so that, if it should tend to run in a slightly oblique direction, it will be maintained in or returned to the desired position.
  • this object is attained by providing one or more pairs of guiding means which are movable perpendicularly to the axis of the strip and wherein those of each pair are disposed directly opposite to each other at both edges of the strip.
  • Each of these guiding means comprises a guiding element and a supporting slide member therefor which is capable of reciprocating within a normally stationary slide carriage or housing for a relatively short distance between two fixed stops in a direction transverse to the edges of the strip, and this distance is adjustable, although it is always considerably smaller than the tolerances in the width of the strip which are normally to be expected.
  • Each guiding element is pressed against the edge of the strip or against the respective stop by a relatively weak spring which only needs to be strong enough to compensate for the friction caused by this guide element and the other elements within each carriage.
  • a hard spring for example, a cup spring
  • a hard spring for example, a cup spring
  • the normally stationary carriages for each pair of guiding elements are adjustable relative to each other, for example, by an electric motor and a screw spindle with right and left-hand threads, and such an adjustment may be carried out manually by the operation of a pushbutton for the purpose of adjusting the guiding elements to the normal width of the strip and also automatically by means of a limit switch with which each slide carriage is equipped and which is actuated by the stroke of the guide element.
  • Each limit switch has, for example, three switching positions so that both limit switches together are capable of attaining nine possible switching combinations for controlling the electric motor. Two of these nine combinations are employed for starting the motor in its two different directions of rotation, while all of the other seven switching positions will either cause the motor to stop or not permit it to start.
  • the limit switch which is installed in each carriage is adapted to be adjusted in such a manner that the stroke of this switch which is smaller than the stroke of the guiding element may be carried out at any desired location within the distance of the stroke of the guiding element and that, if desired, it may also be adjusted so as to change the length of its stroke.
  • the present invention therefore consists in the application of these five features and their combination and association with each other, whereby all of the requirements for properly guiding a metal strip will be accomplished so that, for example, the strip may be guided along one edge, for which purpose it is merely necessary to adjust the carriage on the side opposite to this edge, or the strip may be guided so that its central axis always remains in a constant position by carrying out an adjustment of both carriages in opposite directions symmetrically to the central axis of the strip, while the pressure upon the edges of the strip may be manually adjusted as desired at any time during the guiding operation.
  • Another feature of the invention consists in the possibility of connecting auxiliary devices in a very simple manner to the adjusting means for the carriage for indicating or registering at any time or continuously the Width of the metal strip or for giving a signal whenever the strip exceeds or is narrower than a certain desired Width.
  • FIGURE 1 shows a longitudinal section of one of a pair of associated slide carriages while,
  • FIGURE 2 shows the aforesaid pair of carriages and their associated relationship.
  • each guide element 1 is illustrated in this particular embodiment of the invention as consisting of a roller which is rotatably mounted in a bifurcated slide member 7 and adapted to engage upon one of the edges of the strip 8 which is to be guided.
  • Slide member 7 is slidably guided in a socket of a housing or carriage 2.
  • a coil spring 3 and a cup spring 4 are mounted within this socket so that the slide member 7 will be pressed with a relatively Weak pressure in the direction of the arrow 19.
  • slide member 7 is capable of carrying out a stroke H, the end positions of which are determined by the cup spring 4 when in the flattened condition and the front end of a bushing 11 which is threaded in the bottom of the socket and mounted on the shaftlike extension of slide member 7 so as to be rotatable and axially slideable thereon.
  • Bushing 11 is adjustable to different positions in its axial direction relative to carriage 1 and from the outside thereof by means of a shaft 9 with a square outer end and a pinion 10 on its inner end which engages with a set of gear teeth on the threaded bushing 11.
  • bushing 11 When shaft 9 is turned in one or the other direction, bushing 11 is screwed either toward or away from cup spring 4, whereby the length of the stroke H of slide member 7 may be regulated. As shown, a nut for a selective abutment by bushing 11 is disposed on the shaft-like extension of slide member 7 in normally spaced relationship from the bushing to afford a variable clearance I-I-x.
  • the rear end of the shaftlike extension of slide member 7 carries a pin 12 which acts upon a contact arm 13 of a limit switch 5 provided with leads 18. The particular position where the limit switch 5 may carry out its stroke may be varied by means of a setscrew 14.
  • the two carriages 2 which are associated with each other and may form one of several pairs are connected with each other by means of a spindle 15 with right and left-hand threads which is adapted to be driven in either direction by an electric motor 6 through a reduction gear 16 so that, by means of a nut 17 which connects each carriage 2 with spindle 15, both carriages may be moved toward each other when the Width of strip 8 decreases or away from each other when the width of the strip increases.
  • the electric circuit of the two limit switches 5 of each pair of associated carriages 2 for operating the motor 6 is not illustrated in the drawings as its design will be obvious to any person familiar with the art.
  • the end 20 of spindle 15 may be connected to any desired auxiliary devices, for example, to an indicating instrument which may also be provided with a recording device and signal means for measuring and indicating the width of the metal strip.
  • auxiliary devices are also not illustrated in the drawing since they may be of various designs.
  • each of said guiding means comprises abutment means, each of said slide carriages comprising socket means, a spring abutting each of said abutment means and said socket means and yieldingly opposing said longitudinal move ment of said guiding means in the direction of a respective one of said switch means.
  • An apparatus further comprising means for adjusting the length of said stroke of each of said guiding means, including an abutment member on each of said slide carriages, each of said socket means comprising a threaded bushing member adjustably threaded on a respective one of said carriages, and a spring member interposed between a respective said abutment member and a respective said threaded bushing member.
  • said spring member comprising a cup spring abutting each said abutment member and an end of each said threaded bushing, the tension of each said cup spring being adjusted by adjust ing movement of a respective threaded bushing.
  • each of said 2,301,308 7/1957 cubeuis 200*61 switch means being provided with set screw means for varying the position of said switch means on a respective BERNARD GHHEANY Pnmm'y Exammer' carriage. NEIL C. READ, Examiner.
