Definitions

  • the invention relates to a brake device for rodless working cylinders, preferably for stopping, holding and positioning fluid-driven piston rodless working cylinders, which are operated, for example, by means of a rotating transmission element, e.g. a steel belt, a power bridge, a magnetic field or the like. Transfer the driving force of the piston to a decrease in force, this braking device being actuated by a fluid, a spring or the like.
  • a rotating transmission element e.g. a steel belt, a power bridge, a magnetic field or the like.
  • Actuators in general such as fluid-driven piston rodless drives, for example, must be able to be stopped, held and also positioned precisely if they are to be able to fully perform a variety of tasks.
  • the braking of such a drive for example a pneumatic cylinder, a so-called band cylinder or the like. is practically difficult to solve. This is due to the nature of these drives, especially if the drive means is a compressive fluid, for example a gas, and in addition changing loads on the drive have an additional effect.
  • the parking brake consists essentially of an aluminum housing attached to the cylinder head, an eccentric with clutch lever and a single or double-acting pneumatic cylinder.
  • the piston rod of the drive is guided within the eccentric and slidably supported within the aluminum housing.
  • Systems which act as safety devices and are dependent on the internal pressure in the cylinder are also known, in this case a spring element responds to a specific differential pressure and the piston only runs to a standstill.
  • rodless working cylinders e.g. Band cylinder, rope cylinder or the like
  • a locking device acting on the piston rod of the drive cannot be used due to the lack thereof. It can also not be modified so that it can be movably attached to the cylinder tube of a band cylinder or the like.
  • the locking device is fastened to the cylinder tube of a band cylinder, namely immovably, then it would have to have the movable transmission member, e.g. brake the steel belt, i.e. a link that is intrinsically difficult to handle and is loaded to the limit of its permanent load.
  • a braking device for a band cylinder should follow the movements of the band or another transmission element and be able to support itself on the cylinder tube.
  • the invention is therefore based on the object of possessing a braking device for stopping, holding and positioning for fluid-driven cylinder drives, for example belt cylinders or the like, which requires particularly little space and certainly avoids the disadvantages of the known devices of this type.
  • the braking device concentrically surrounds the cylinder tube with at least one brake pad and is integrated in the power take-off.
  • the braking device consists of a bellows which is placed around the cylinder tube and can be filled with a fluid as a drive for the brake linings.
  • Another advantageous embodiment provides that one or more pistons which can be acted upon by a fluid are arranged, which act on the brake linings via a cone and are held in their rest positions by spring force.
  • the brake device proposed according to the invention and integrated into the power take-off of a rodless working cylinder and comprising the cylinder tube with at least one brake pad is to be seen in particular in that overstressing of the transmission member, i.e. the belt, rope or the like, is avoided with certainty will, with full usability of the available braking energy and further to the fact that the braking device can be used universally, which is to be understood as the possibility of being able to place the braking device on a wide variety of fluid-driven drive systems. It is thus even possible to master the so-called load limit case, that is, if the deceleration is greater than the force for which the drive element, in particular the transmission element, is designed.
  • the braking force available can be greater than the driving force, so the braking device then acts completely independently of the pressure prevailing in the cylinder. It is also advantageous that the braking device acts on the outer circumference of the cylinder tube and not by means of spring-loaded rollers on the inner running surface of the cylinder, which must not be exposed to any foreign bodies.
  • Rodless working cylinders for which the object proposed by the invention is particularly suitable, are understood to mean drives in which the force of the cylinder, ie the drive element, either via a power bridge through a slot in the cylinder tube or via magnets or via circumferential belts, ropes, Steel wire-plastic straps or combinations thereof is transferred from the piston to the outside.
  • a rodless cylinder is shown in the form of a band cylinder.
  • the cylinder tube itself is labeled “1”
  • the piston "2” which is shown in a broken window of the cylinder tube "1”.
  • the transmission link is shown as a steel belt.
  • This steel belt “3” is attached to the piston “2” on the right and left and runs over rollers "4" and “5" in the cylinder heads "6" and “7”.
  • the power take-off "8” is fixed with the tape “3” connected.
  • the braking device “9” is firmly integrated into this power take-off "8".
  • With “10” is a nozzle for the supply of fluid for the ' braking device.
  • FIG. 3 shows an embodiment variant of the braking device.
  • a bellows "11” there are two annular pistons “13a” and “13b”.
  • the two ring pistons “13a” and “13b” are clamped against each other by means of a spring “14” and pressed into their end positions.
  • the pistons “13a” and “13b” act on the actual brake element, which consists of one or more brake pads “12, via transmission members” 15a “and” 15b ", which have a conical running surface, via correspondingly shaped counter-members” 16a “and” 16b “ “consists of.
  • "17” and "18” denote sliding bands with which the braking device "9” can slide on the cylinder tube "1".
  • the fluid is fed in the braking direction via feeds "19” and "20".
  • FIG. 4 shows a section through the braking device according to FIG. 3. From both figures it can be seen that the braking device of this embodiment variant serves to hold the power take-off "8" at a specific location and to cancel this positioning when the fluid is fed through the feeders "19" and "20". Thus, the power take-off "8" can be moved again by the piston "2" until the pressure of the fluid in the braking device is released.
  • Figure 5 shows a longitudinal section through an embodiment with one or more pistons "26a” and “26b” instead of the annular pistons "13a” and “13b". If several are provided, these pistons "26” are arranged in a circle around the cylinder tube.
  • FIG. 6 acts in the opposite way to that described in FIGS. 3 and 4, that is to say corresponding to FIG. 2.
  • the annular piston “13a” and “13b” is also tensioned in the outer position by the spring “14” held, however, that is conical Transfer member of the image 3/4 shown "15a” and “15b” as the transmission member "21” or “22” responsive to a G egenglied “23” act, but in a reverse manner, namely so that, when acting upon the piston “ 13a “or” 13b “are pressed by a fluid, the transmission members” 21 “and” 22 "against the conical surface of the counter member” 23 “and thus the brake pads” 12 "are pressed onto the cylinder tube” 1 ", ie the decrease in force” 8 "is brought to a standstill.
  • FIG. 7 and 8 show a further embodiment variant in which, instead of the annular pistons "13a” and “13b", several individual pistons “24", “25”, “26”, “27” and “28” occur. Two individual pistons work together. From Fig. 7 it can be seen that the transmission members press the brake cone by means of spring tension, the brake "12" is thus fixed, i.e. pistons "26a” and “26b" are not under fluid pressure.
  • the rodless drive as shown in these two figures, consists of a slotted cylinder tube "29" in which there is a piston "30” which forms a unit with the power bridge "30a".
  • Braking by means of electromagnets is a further possibility, not shown, of equipping the subject of the invention, it also being possible here to advantageously use the cone principle used.
  • the function of the brake device proposed by the invention is independent of the pressure conditions prevailing on the piston “2” or in the cylinder tube “1”.
