Definitions

  • the invention relates to a device for clamping a piece of tissue according to the preamble of claim 1.
  • DE-A-36 01 167 discloses an automatic silk tensioning device for tensioning silk on a silk screen printing frame.
  • the silk is stretched on four sides using a clamp table and in a second stretching process using stretchers on the clamp table.
  • a pressure frame is lifted onto a lifting table and pressed against the silk.
  • an adhesive is applied to the frame and dried artificially.
  • the excess silk surrounding the frame is then cut away, the frame covered with silk is removed and an empty frame is fed.
  • the inventor has set himself the goal of improving the device of the type mentioned at the outset while avoiding the identified defects and of making the adaptation of the pressing force on the clamping jaws controllable during the clamping process.
  • a further closing path is arranged after the first closing path determined by the closing lever; the latter is controlled by a piston rod of the cylinder / piston unit, and the piston rod allows the cylinder to assume a first opening position of the clamping jaw close to the clamping jaws and, after a partial stroke, a middle position with the clamping jaws closed, and a subsequent stroke path on which the clamping process takes place .
  • a piston disk is preferably assigned to the piston rod as a piston.
  • a short-stroke cylinder is provided, by means of which the respective clamping jaw can be arranged below the surface of the printing frame before the piece of tissue is inserted and can be closed after insertion, after which that short-stroke cylinder can be actuated to unlock a slide and the clamping jaw can be actuated above the surface is adjustable.
  • the clamping jaw should also be held in this gripping position until a latching member for the short-stroke cylinder is released, the piston disc being able to be guided into the middle position over the partial stroke length.
  • the cylinder held at the end by a swivel bearing on the base or base profile is displaceably mounted on the other side in a pipe socket on which the piston rod is fixed with its end remote from the piston.
  • the piston rod passes through an end plate of the cylinder, wherein the piston rod rests movably in its sealed through bore.
  • the guide element is advantageously a bracket, the legs of which overlap the two side surfaces of the profile and are connected to the slide by an axis of rotation. Parallel to the latter, the slide carries a pivot axis for a hood-like support member of the movable jaw.
  • the hood-like support member as a swivel body with parallel side walls - flanking the pipe socket - connects to the swivel axis of the slide and holds the jaw from above with a front edge parallel to the swivel axis.
  • the hinge point for the pipe socket on the other side of the axis of rotation on the stirrup leg should be opposite a hinge point for a handlebar rod, which is articulated on the other side of its swivel body.
  • a hinge pin is connected as a hinge between the handlebar and swivel body - via a bolt rotatably mounted therein - with a rocker arm, the other end of which offers an elongated hole to a hinge axis of the bracket.

  • n Approximately in the middle between the axis of rotation 44 and the hinge point 56 - and laterally offset by a dimension n of approximately 18 mm - there is also a hinge pin 62 on the leg 47 of the bracket 46, which bolt moves into an elongated hole 63 within the swivel body 40 Swing arm 64 reaches.
  • the path of the individual parts 40, 46, 57, 64 from the open position of the clamping jaws 32, 36 indicated by the broken line about the pivot axis 42 and axis of rotation 44 into the closed position can be seen in FIG. 6.
  • the hinge pin 52 generates a circular contour K1 about the axis of rotation 44 on its way, the hinge point 56 a circular contour K2.
  • These paths K1, K2 result in a circular contour K3 as the movement path of the articulation pin 58.
  • the upper end of the rocker 64 is designed according to FIG. 8 as a round end pin 65, which is encompassed by a helical spring 60, and is rotatably attached to the articulated pin 58 of the handlebar rod 57.
  • This hinge pin 58 is seated in a bearing pin 66 of diameter f of approximately 16 mm, which in turn is surrounded by a sleeve 68 which is welded on the inside to the roof part 38d of the apron 38.
  • This sleeve 68 offers on the downward part of its circumference a guide slot 69 for that end bolt 65.
  • an axle eye in the head of the handlebar rod 57 is of a pin-like shape of the bearing pin 66 enforced and connected in this way to the depository.
  • the pipe socket 54 which is closed at the end with a plate 55 and - as mentioned - attached to the bracket 46 by means of articulated bolts 52, receives the head end of the pull cylinder 20 mentioned at the beginning.
  • a diametrical yoke rod is provided instead of the end plate 55.
  • the tube wall 80 of the pull cylinder 20 is seated with its end distal to its end wall 75 sealed at an end plug 82 which is articulated at 84 to a rear flange 86 projecting from the base rail 22.

  • the clamping jaw 18 can be opened by manual actuation of the closing or hand lever 50, but is normally carried out pneumatically, in that fluid enters the pull cylinder 20 and acts on the piston disc 78.
  • the piston disc 78 is from any position of the Stroke h moved to the central position II in the open position I.
  • the carriage 28 is also brought into the front position and fixed, a locking pin 90 guided in a U-profile 91 being pushed by a spring 60 a along an inclined surface 92 of a link block 93 into the provided recess 94.

  • the hinge pins 62 of the pair of the rocker 64 are seated on their respective elongated hole bases and lie behind the associated handlebar rod 57 by the amount n of lateral displacement mentioned.
  • This prestressing process described can also be carried out pneumatically, in that fluid is applied to the piston disk 78 via the prechamber or the pressure chamber 88 and is pushed from the open position I shown in FIG. 11 into the central position II over a partial stroke length h1 of approximately 50 mm.
  • the short-stroke cylinder 27 fastened to the wedge profile 24 is controlled via a line 97 indicated in FIG. 3 in such a way that the link block 93 is lifted out of the locking position and releases the slide 28 so that it can be guided in the pulling direction x.

This distance from the frame 14 serves above all to avoid injuries to the web 12 when Clamping process.
  • the pre-chamber 88 delimited by the end wall 75 and the piston disk 78 is acted upon by pneumatic fluid via a line indicated only in FIG. 3 at 95, thereby generating an adaptable pneumatic closing force on the clamping jaw 18, in addition to the mechanical closing force.
  • the distance i of FIG. 11 relative to the partial stroke length h1 to the full stroke length h determines the possible clamping path of the tensioning device 16 - but usually the full stroke length h is not used at all.
  • the clamping jaw 18 is lowered into the position described for FIG. 3, so that the web 12 rests on the frame 14 for gluing.
  • an indentation on the inner surface of the rear plug 82 of a further exemplary embodiment is merely indicated above the longitudinal axis A at 98.
  • the piston rod nut 73 holding that piston disk 78 is immersed in this recess 98 in the end position III, whereby the stroke length is extended by the depth dimension k of the recess 98.
  • the piston disk 78 By introducing fluid into a rear chamber 89 with variable volume between the piston disk 78 and the end plug 82 via a further line 96 (FIG. 3), the piston disk 78 can be pressed against the pulling direction x in addition to the mechanical return, in order to clamp the jaw 18 to open.
