Definitions

  • the invention relates to a tool of the type mentioned in the preamble of claim 1.
  • Barrels for example the usual 200-liter barrels, are mainly used to transport dangerous liquids that must be sealed with a high degree of security.
  • the standardized closure system of today's barrels therefore has, in addition to the screw closure, a sealing cap with its own seal, which grips over the closed bunghole and is secured below it by bending. Closing tools of the type mentioned at the beginning are used for this purpose.
  • rocker arms which are provided concentrically around the actuation axis and, with their working end, embrace the sealing cap.
  • the levers With a conical actuating surface actuated in the axial direction, the levers are actuated in such a way that the working ends are pressed together and, with correspondingly shaped surface pieces, compress the sealing cap on all sides and thus clamp on the bung of the barrel. After pulling back the conical actuating surface, the levers are spread out again under spring force and release the sealing cap.
  • this known construction has considerable disadvantages. Even with careful maintenance and especially lubrication, this construction tends to jam frequently. This tool is therefore less suitable for maintenance-free automatic operation, for example for filling highly dangerous or explosive liquids.
  • the actuation stroke is very short. High actuation forces must therefore be applied, which in the case of the known construction mentioned requires two large-area pneumatic cylinders operating in parallel. The short actuation stroke makes function monitoring difficult.
  • the object of the present invention is therefore to create a tool of the type mentioned at the outset which is distinguished by a simpler construction and greater reliability.
  • the levers are designed with one arm, so they are actuated at the end of work.
  • the levers are supported in a tilting manner in the middle area and form the arm actuated outwards at one end and the working end working inwards at the other end.
  • the kinematic requirements for this construction are considerably more favorable. In particular, any risk of pinching is avoided.
  • the cone angle can be kept very flat, so that there is a long actuation stroke. Therefore, the actuation forces are small and there are good possibilities for monitoring the working cycle due to the long stroke.
  • Another advantage is that both the lever and the housing are fixed in the direction of actuation and the actuation stroke is only exerted by the cone and its actuators. The moving masses are therefore considerably smaller than in the known construction.
  • the tool according to the invention can be constructed more simply and cost-effectively with a very high level of functional reliability.
  • the features of claim 4 are advantageously provided. With a split ring groove, the construction is very easy to assemble.
  • the levers which are essentially sector-shaped in the axial section, can in this way be designed so that they touch each other without play, so that they are held captively without additional securing means.
  • the tilting parts of the levers can move with play to one another without the risk of pinching. They only touch in the area of the tilt axis of the levers, in which play is not required, and are thus precisely adjusted on the circumference.
  • the tool shown in Fig. 1 has a housing with a cylinder wall 1 which is arranged concentrically to an actuation axis 12 and which is closed at one end by a transverse wall 2.
  • a ring 4 is attached with a parting line 3 and held detachably in this position by means not shown.
  • An annular groove 5 is formed in the inner wall at the parting line 3.
  • a number of levers 6 are arranged concentrically and essentially parallel to the actuation axis 12 in the interior of the cylinder wall 1.
  • the levers 6 have on their outer side an outwardly projecting flange 7 which, as shown in FIG. 1, is rounded to match the cross-sectional shape of the annular groove 5.
  • the levers are each mounted with their flange 7 in the annular groove.
  • the levers each extend from the position of the flange 7 in both directions to ends, of which the end facing away from the transverse wall 2 of the housing represents the working end 8, which on the inside, as shown in FIG. 1, is designed in a known shape as a clamping tool is, and is adapted to the desired clamping shape of the sealing caps, not shown, to be closed with the tool.
  • the opposite end of the lever 6 is the actuating end 9, at which the levers are acted upon.
  • the levers at the actuation end 9 have the inward-facing cams 10 shown in FIG. 1, which slide on the outer actuation surface of a cone 11, which is driven back and forth in the actuation axis 12 coinciding with the axis of the cylinder wall 1.
  • a piston rod 13 of a piston 14, which is pneumatically driven in a cylinder 15, is used to drive the cone 11 in the actuation axis 12.
  • the cylinder 15 is, as shown in FIG. 1, in an axis extension on the transverse wall 2 of the housing attached and fastened there by means not shown, the piston rod 13 passing through the transverse wall 2.
  • the piston 14 is pneumatically actuated from above against a return spring 16.
  • the return spring 16 is omitted and the cylinder 15 is designed for pneumatic actuation of the piston on both sides.
  • Other drives for the piston rod 13 can also be provided, for example electromagnetic drives.
  • FIG. 1 shows two different operating positions within the housing 1, 2 on the right and left of the actuation axis 12, namely on the right side the unactuated position when the cone 11 is raised and on the left side the actuation position when the cone 11 is pushed down.
  • very flat cone angle of the cone 11 there is a long stroke for the actuating piston 14.
  • the power transmission is large, so that the piston can be correspondingly small.
  • the functional play of the tool shown can be monitored well, for example for electronic purposes Function feedback.
  • a mark 18 can be provided at the upper end of the cone 11, which is monitored by sensors 19a and 19b attached to the housing, which sensors indicate the end positions of the actuation stroke.
  • the actuating end position is shown, in which the cone 11 has reached its lowest position and the working ends 8 of the levers 6 are radially compressed to the end position. Then the cone 11 is pulled back into the position shown on the right side of the figure.
  • the working ends 8 of the levers can radially diverge again.
  • the levers 6 make a radial movement at both ends. They must therefore have mutual play on all of their side surface parts which perform a tilting movement, since they would jam in the case of a tilting movement if they were to be exactly sector-wise divided. However, if the levers had play to one another in all side surface parts, the levers could fall out of the housing 1, 2. There would be additional mounting measures, such as circlips or the like. required.
  • the levers advantageously have essentially the shape of their side faces shown in FIG. 4, viewed in the axial direction. The sector in which the lever 6 shown lies is shown in broken lines. The side faces are drawn in opposite to the dashed sector boundaries. Only the side surfaces 21 of the flange 7 extend exactly to the sector boundary. The levers therefore lie against one another with these side surfaces 21, but apart from that at a clearance of one another.
  • the levers are held captive without additional safeguards. However, they can only be inserted into the ring groove 5 together. Therefore, the annular groove can be made divisible by removing the ring 4 from the cylinder wall 1.
  • the lever 6 ' is in turn tilt-mounted on the outside of the cylinder wall 1', also with a groove / flange bearing.
  • the flange 7 ' is designed as an inward-pointing ring flange on the cylinder wall and the groove 5' as a groove in the outside of the lever 6 '.
  • the flange not only effects the tilt support of the levers 6, 6 ', but also the fixing of the levers in the direction of the actuation axis 12.
  • the levers are held captively and against those acting in the axial direction Powers secured.
  • levers With their working end 8, which is designed on the inside in a suitably shaping manner, the levers should press a thin-walled sealing cap, not shown, on the closure of a barrel radially from all sides. It should be avoided that pressure marks appear in the joints between the levers on the surface of the sealing cap. For this reason, the largest possible number of levers should be provided. At least 10 levers should therefore be arranged on the circumference. At least 15 levers are advantageously provided. Experiments with 18 levers have proven to be optimal.
