Definitions

  • the invention relates to a drive and guide system for a load to be moved, consisting essentially of a rodless pressure medium cylinder, the cylinder body of which comprises a piston which is guided in a longitudinally displaceable manner, and a force transmission element connected to the piston of the pressure medium cylinder, which is arranged on rollers mounted thereon with in the longitudinal direction of the cylinder body Raceways interact and are connected to the load to be moved, the cylinder body being held stationary, for example on a vehicle or building.
  • a drive and guide system with a rodless pressure medium cylinder is known, the piston of which is connected to a power transmission element which is approximately T-shaped in cross section.
  • the two horizontally arranged legs of this transmission element each carry a concave or convex roller.
  • These rollers can be rotated about vertical axes and interact with reversely convex or concave raceways on the narrow sides of a guide rail that runs horizontally and parallel to the cylinder body.
  • the cylinder body and the guide rail are connected to each other by screws.
  • a cladding profile is screwed to the cylinder body, which surrounds the cylinder body and the power transmission element in the region of the roller guide.
  • a disadvantage of the known drive and guide system lies in its construction from separate parts which have to be joined together with the aid of separate screws and holes and threads to be created for this purpose.
  • the greater need for installation space resulting from the special cladding profile is also considered unfavorable. Otherwise, the above-described operative connection of the profile rollers with the raceways of the guide rail is unsuitable in the event that a load with a considerable weight is connected to the force transmission element. Because in this case, all vertical forces and also bending moments effective transversely to the direction of movement would have to be absorbed disadvantageously solely via the profiles of the rollers and the guide bar.
  • the invention has for its object to design a drive and guide system of the generic type in the simplest possible manner such that a particularly compact and inexpensive design is available; high vertical forces and bending moments should be absorbed perfectly and, in addition, quiet, smooth running behavior should be achieved, which also allows the load to be moved manually.
  • this object is achieved in that the cylinder body and the raceways are formed together by a one-piece profile, this profile contains the pairs provided, functionally divided into support rollers and support rollers, which consist of non-metallic material at least in the area of their tread, and that the support rollers and the support rollers are arranged below the cylinder body, the axis of rotation of these rollers and the direction of action of the load being at an angle of 90 ° to one another.
  • the cylinder body has a sealed longitudinal slot arranged in the interior of the one-piece profile parallel to the raceways. This is done According to a further development of the invention, the power transmission on the one hand between the support rollers or the support rollers and the raceways and on the other hand between the profile and its fixed mounting in common working planes, so that no moments changing the width of the sealed longitudinal slot occur.
  • a next embodiment of the invention is that the support rollers and the support rollers are each mounted at the ends of the power transmission element to achieve the largest possible support and support base. It is recommended, for. B. for reasons of rational production, according to a supplementary embodiment of the invention that the support rollers and support rollers arranged at the ends of the force transmission element are arranged symmetrically with respect to the longitudinal center thereof.
  • a next embodiment of the invention is that the support rollers are connected to the force transmission element so as to be adjustable in the direction of their career.
  • the low-noise and easy running of the power transmission element already achieved by the at least circumferentially non-metallic rollers is improved according to a further embodiment of the invention in that the raceways and the support rollers and the support rollers are designed in their cross-section such that the rollers on both sides in a linear shape Be in contact with the raceways.
  • the rolling path of the force transmission element within the profile is limited by adjustable stops, that interact with noise-absorbing elastic blocks.
  • a further embodiment of the invention offers that a deflection roller for a band or rope connected to the force transmission element is mounted on the two longitudinal ends of the profile .
  • a second force transmission element for a further load is connected to the belt or rope, this second force transmission element likewise carrying rollers and has the support rollers, but is not connected to the piston of the pressure medium cylinder.
  • a further embodiment of the invention offers that one of the two deflection rollers is coupled to a position measuring system.
  • a design according to the invention consists in that one of the two deflection rollers itself is designed as a signal disk or is coupled to a separate signal disk, this deflection roller or the separate signal disk interacting with simple electrical signal transmitters in such a way that the pulses of the signal transmitters for speed monitoring and / or can be evaluated for the detection of the direction of movement of the load.
  • a further embodiment of the invention provides that a locking mechanism is mounted within the one-piece profile, which interacts positively with the force transmission element or parts connected therewith.
  • the profile is provided with grooves for receiving strip-shaped permanent magnets or steel strips.
  • the drive and guide system according to the invention is characterized in particular by its compact design, which is particularly suitable for cramped installation conditions.
  • the one-piece profile, in which all drive, support and guide elements are combined, as well as the arrangement and design of the rollers according to the invention meet all the requirements for a high load capacity and smooth, low-noise and low-maintenance operation in a cost-effective manner.
  • the one-piece profile screwed to a fixed holder 7 has a cylinder body 2 of a rodless pressure medium cylinder and raceways 6 for rollers 5.
  • the one with a sealed longitudinal slot 2a provided cylinder 2 contains a longitudinally displaceable piston 3, to which a power transmission element 4 is connected, which is formed similar to a carriage and in the present embodiment from a plurality of components screwed together.
  • This element 4 is connected via support arms 4a to a load 1 to be moved, for example a relatively heavy sliding glass door.
  • the rollers 5, arranged in profile below the cylinder body 2 and supported at the ends of the force transmission element 4, are functionally divided into support rollers 5a and support rollers 5b and are each provided in pairs.
  • the support rollers 5b are adjustably connected to the force transmission element 4 in the direction of their track 6.
  • the raceways 6 and the support rollers 5a formed at least in the area of their running surface from non-metallic material and the support rollers 5b are coordinated with one another in their cross section such that the rollers 5a and 5b are in linear contact with the raceways 6 on both sides. This can be easily achieved, for example, by designing the rollers 5a and 5b in the area of their running surface as semicircular as shown and the raceways 6 in cross section similar to a Gothic arch (not shown).
  • the axis of rotation of the support rollers 5a and the support rollers 5b and the direction of action of the load 1 to be moved are at an angle of 90 ° to one another.
  • the power transmission takes place on the one hand between the support rollers 5a or the support rollers 5b and the raceways 6 and on the other hand between the profile and the fixed holder 7 in common working planes, so that none of the width of the longitudinal slot 2a changing moments occur.
  • the profile has grooves 11a in which strip-shaped permanent magnets or steel strips 11 can be embedded.
  • a pulley 9 for a rope 10 is mounted on the two longitudinal ends of the profile, the z. B. consists of steel with a casing made of plastic.
  • This cable 10 is fastened to the force transmission element 4 by a clamp connection (see FIG. 6).
  • a second force transmission element 4 'for a further load 1' which is to be moved in opposite directions is connected to the side of the drive cable 10 which is opposite in the longitudinal direction and rearward in relation to FIG. 1B.
  • the second power transmission element 4 ' also has the support rollers 5a and the support rollers 5b. However, it is not connected to the piston 3 of the pressure cylinder.
  • the piston 3 of the pressure medium cylinder is pressurized with air on one side or the other.
  • the rolling path of the force transmission element 4 is limited by adjustable stops 8 arranged inside the profile, which interact with noise-damping elastic blocks 8a, which are attached to the ends of the force transmission element 4.
  • the second power transmission element 4 'and thus the further load 1' are simultaneously moved via the cable 10 described.
  • one of the two deflecting rollers 9 is designed as a signal disk, for example by a special profiling of its end face.
  • one of the two deflection rollers 9 can be coupled to a separate signal disk. Said deflection roller 9 or the separate signal disk works with simple electrical signal transmitters together, whose pulses corresponding to the speed of rotation and the direction of rotation can be evaluated for the desired control and control functions.
  • a locking mechanism is mounted within the one-piece profile and interacts positively with the force transmission element 4.
  • This mechanism the z. B. can be operated by hand with the aid of a square wrench or a magnet, allows the load to be moved 1 and possibly also the other load 1 'connected via the cable 10 to be fixed.
