Definitions

  • the invention relates to a device for unscrewing Vascular occlusions according to the preamble of claim 1.
  • Such a construction has the advantage of a simple, inexpensive design because both the lifting and lowering of the Gripping heads as well as opening and closing the Gripping devices through a single stationary lifting curve can be controlled. Separate control curves or Actuators for opening and closing the Gripping devices are therefore not required. Both Known screwdrivers of this type take place on a single point of the orbit of the rotor a complete Open all gripping devices instead. It is therefore the Vascular occlusions regardless of their shape or their Material collected out of order. Is separate disposal, e.g. of aluminum tube closures on the one hand and made of Plastic, on the other hand, if desired, they must Vascular occlusions using separate sorting devices be separated.
  • a device for unscrewing Vascular occlusions are known in which the opening of the Gripping devices with their own stationary control cam in the upper area of the rotor (DE-OS 27 52 035).
  • the stationary control curve has two in different places opening cams arranged in the orbit of the gripping heads on, which can be pivoted at the upper end of the gripping heads arranged levers and a stationary switch can be approached.
  • the switch is operated by a sensor scanning the vascular occlusions, so that Vascular occlusions with any number of different criteria can be sorted reliably.
  • the invention has for its object in a Device for unscrewing vascular occlusions of the type mentioned with little additional effort reliable sorting of any number To allow caps.
  • the transport star 9 is rotatably fixed with a rotor 2 connected, which rotates together with him about axis 8.
  • the Rotor 2 has the shape of a horizontal circular disk and is at the bottom outer edge with a number of Flanged 10 assembled. These sit evenly distributed on a pitch circle, which is arranged concentrically to axis 8 is.
  • each spindle 11 there is a vertical spindle 11 in each flange bearing 10 both rotatable and raised and lowered. With the upper end of each spindle 11 is not shown Slewing ring and straight guide a cam roller 12 connected, which engages in a stationary stroke curve 13. This controls the rotation of the rotor 2 Height movement and height position of the spindles 11. Simultaneously are these with a stationary ring 14 Internal toothing and meshing gears 15, the non-rotatable, but displaceable, each with a spindle 11 are coupled, set in self-rotation.
  • each spindle 11 there is a gripping head 3 a controllable gripping device 6 for the two types attached by caps 1.
  • the gripping device 6 consists essentially of four staggered by 90 degrees double-armed gripping levers with at the lower end Gripping jaws 16 are provided for the caps 1 and at the upper end by compression springs 17 in the closing direction be charged.
  • Between the gripping jaws 16 and Swivel pin 18 of each gripping lever is a pressure roller 19 freely rotatable.
  • the four pressure rollers 19 of the Gripping device 6 cooperate with a plunger 4, the is vertically movable in the gripping head 3.
  • the plunger 4 has a sensor pin 20 at the lower end, who recognizes whether a reusable bottle 7 has a cap 1 has or not.
  • An area 21 also follows above small diameter that has a conical Intermediate area into a large diameter area 22 transforms. If the four pressure rollers 19 lie against the area 21, so the gripping device 6 under the influence of Compression springs 17 closed and grips or holds one Locking cap 1. On the other hand, the four pressure rollers 19 are on Area 22 on, the gripping jaws 16 are against the Influence of the compression springs 17 apart and the Gripping device 6 is open. In this position you can no cap 1 can be detected or a previously detected Cap 1 is released.
  • the gripping head 3 consists of two to each other vertically movable, under the influence of a compression spring 23 pieces pushed apart and can be used for Unscrew a cap 1 through the thread follow forced altitude movement.
  • each plunger 4 lies on a block 24 on, which is mounted in a vertically movable manner in the spindle 11 and carries a horizontal cross pin 25. This penetrates two opposite slots 26 of the spindle 11 and carries a rotatable roller 27 at both free ends.
  • Stop 5 At the bottom of the rotor 2, more precisely that Flange bearing 10 is a separate one for each gripping head 3 Stop 5 provided. This has an annular shape and is at a distance concentric with the associated spindle 11 arranged and by means of several vertical bolts 28th suspended in height and rotatably on the flange bearing 10. Each stop 5 has two defined altitudes: the is widened by heads at the top of the lower one Bolt 28 defined, while the upper one by a direct Contact between the stop 5 and the lower end face of the flange 10 is determined. At the radially outward-facing side of each stop 5 is one rotatable cam roller 29 attached, which with a stationary curve piece 30 cooperates.
  • the curve piece 30 is part of a control device 31, with the each stop 5 optionally in its lower altitude can be blocked or released if a Passing gripping head 3 under the influence of the stroke curve 13 is raised.
  • the control device 31 also has a bearing block 32 on the underside of the stationary Rings 14 is attached, approximately at the level of the flange bearing 10 with some distance to them.
  • In the bearing block 32 is one horizontal shaft mounted on the radially inward pointing end of said curve piece 30 and at their a lever 33 is fastened radially outward end.
  • the piston rod of a pneumatic cylinder engages on this 34 on, which is articulated on the bearing block 32.
  • the curve piece 30 takes the one in FIG dash-dotted lines, upwards swiveled inclined position. In this inclined position it has Curve piece 30 no contact with the passing Stop 5 or its cam roller 29.
  • the control of the pneumatic cylinder 34 or its Solenoid valve is carried out by an electronic device 35 a freely programmable control, on the one hand a clock generator scanning the rotating movement of the rotor 2 36 and on the other hand is connected to a sensor 37, of the material of the caps 1, plastic or Aluminum, appeals.
  • the sensor 37 can directly in the Area of the bearing block 32 at the level of a screwed off Cap 1 but also in the inlet of the device, e.g. on an inlet screw, not shown, or not shown star in the height of the caps 1 be arranged. In the latter case, the Signals of the sensor 37 in the device 35, for example by a Shift register, required until the relevant Cap 1 in the area of the control device 31 arrives.
  • the Curve piece 30 in the stroke curve 13 an increase H1 educated.
  • This causes the cam roller 12 and Spindle 11 a corresponding stroke of the continuous Gripping head 3.
  • the gripping device 6 opened and the previously unscrewed in the usual way Cap 1 with the cooperation of the feeler pin 20 pushed out.
