Definitions

  • the invention relates to a linear drive device with heavy-load guiding means, with a guide structure having two longitudinally spaced along parallel alignment with longitudinal members, which are combined by a cross between them existing bridging connection means to form a rigid assembly and each carrying a longitudinal guide rail, with a the two guide rails linearly displaceably mounted lifting carriage and with at least one along the stroke of the lifting rod extending rodless linear drive, the output member is drivingly coupled to the lifting.
  • Linear drive devices of this type are used in particular when relatively heavy components are to be displaced linearly and / or positioned, wherein they can also be used to construct multi-axis systems.
  • a linear drive device of the type mentioned is known, which has two guide rails each carrying a longitudinal rails, which are an integral part of a U-shaped profile element. On the guide rails is a the space between the two longitudinal beams bridging Hubschlitten slidably mounted.
  • the two longitudinal beams of the guide structure are designed as separate components, of which at least one of the at least one rodless linear drive is formed, wherein the connecting means is arranged in the space defined between the two longitudinal beams.
  • the independent realization of the two longitudinal beams allows, together with the associated connection device, the realization of management structures of large size, so depending on the application with long length and / or large width and / or high altitude.
  • the management structure is not to be manufactured here as a single component, but it is a production in smaller individual components possible, which are then assembled to the management structure.
  • the at least one rodless linear drive is executed in unit with at least one of the longitudinal beams, no installation space is required for the installation of the linear drive to the longitudinal beams, which allows compact dimensions of the linear drive device, especially in the width direction, regardless of the currently selected size.
  • the space between the two longitudinal beams can be used for space-saving accommodation of the connecting device.
  • Another advantage is that through the integration of linear drive and longitudinal beam an automatic parallel alignment of guide means and drive means takes place, which simplifies the assembly of the linear drive device and still combines high precision with low susceptibility to wear during operation.
  • both longitudinal beams are preferably designed in the form of rodless linear actuators, the output members at the same time drivingly on the lifting can act to perform synchronous operation an exact displacement of the lifting with high driving force can.
  • the at least one rodless linear drive could be designed as an electric drive.
  • a fluid-actuated linear drive is used, in particular a type which is designed for operation with compressed air. If both longitudinal beams formed by linear drives, a hybrid design is possible, wherein it is a linear drive to a fluidic linear drive and the other linear drive is an electric linear drive.
  • a slot cylinder which has a tubular housing part, which is penetrated by a longitudinal slot which is penetrated by a driver element, via which the drive connection between the output member and lifting is made.
  • An identically designed housing part can also be used in a longitudinal beam not designed as a linear drive, it being possible in this case to dispense with the output member in order to save costs.
  • the use of identical parts for the guide rail-bearing component proves to be a further advantage.
  • the preparation of a specifically designed, serving only for guiding purposes component can therefore be dispensed with.
  • the guide rails are expediently arranged in the same direction and in this case by a longitudinal plane extending away from the main longitudinal plane extending between the two longitudinal members.
  • the drive-like coupling between a respective output member and the lifting takes place expediently in the region of the opposite of the guide rail of the other longitudinal spar longitudinal side of the respective associated guide rail.
  • the lifting carriage is particularly easy to implement if it has two separate, each mounted on one of the guide rails sliding carriage, which are interconnected via a rigid support plate. On the support plate fastening means may be provided for attaching the load to be transported.
  • the connecting device preferably contains at least one connecting body, which is accommodated in the intermediate space between the two linear drives and thereby bridges this intermediate space.
  • this at least one connecting body is an independent component, so that trouble-free production is possible independently of the longitudinal bars.
  • the connecting body is ultimately attached to the two longitudinal beams, that together with these forms a rigid assembly, in particular a releasable attachment is present, so if necessary, a disassembly is possible, for example, if a linear drive must be replaced due to a defect.
  • the fixing of the at least one connecting body is expediently exclusively by clamping on each longitudinal spar. An immediate screw connection is therefore unnecessary. This also simplifies fine adjustments of the individual components relative to each other during assembly of the linear drive device.
  • a particularly compact arrangement results when the at least one connecting body is accommodated in its entirety within the intermediate space between the two longitudinal beams. It then protrudes disturbingly at neither of the two open sides of the gap. In particular, it can terminate flush with one of the two open sides of the intermediate space with the adjacent outer surfaces of the longitudinal members lying there.
  • the connecting device contains only a single connecting body of the type described above, which expediently extends from one to the other end region of the two longitudinal struts, so that the latter does not protrude axially or only slightly beyond the connecting body. This results in a particularly rigid connection, which is predestined for the highest demands.
  • connection means includes a plurality of mutually independent connection body, which are placed in the space with axial distance from each other and each cause a rigid connection between the two longitudinal beams. In this way, an extremely stable connection between the two longitudinal beams is still ensured, at the same time results in a not inconsiderable weight saving.
  • At least one of the connecting bodies may be penetrated in its longitudinal direction by at least one cavity opening out to its two end faces.
  • This cavity can serve alone to save weight, but it can also fulfill an additional function, for example, to guide a Fluids or for receiving electrical and / or fluidic conduit means.
  • the at least one connecting body may be equipped with means that allow attachment of additional components present in addition to the longitudinal bars, for example holders for electrical and / or fluidic lines, for sensors, for position detecting means, for controls, such as valves or The like, and / or for an electronic control device used for the operation of the linear drive device.
  • Each connecting body expediently associated with two clamping devices, via which the clamping attachment to the adjacent longitudinal spar is possible. It is advantageous if the connecting body carries the clamping devices, so that they do not need to be handled separately.
  • each longitudinal bars each carry at least one clamping strip, which has an undercut cross-sectional profile, on the outer surfaces facing each other, with which the clamping devices can cooperate.
