Definitions

  • the invention relates to a workpiece carrier system.
  • Workpiece carrier systems are used to transport workpieces to various work stations, such as on a production line.
  • GB 1, 175,786 describes a workpiece carrier system in which the workpiece carriers are designed as carriages which run on rails and are connected to an endless traction means (conveyor belt).
  • the workpiece carriers each have a clamping device with clamping elements, between which the traction means is arranged and by means of which the workpiece carrier can be clamped to the traction means.
  • Pulling means in particular a chain, is guided by which the workpiece carriers supported in particular on it are carried along by frictional force.
  • the chain is deflected at two deflection points, one of which is driven.
  • EP 1 999043 B1 describes a workpiece carrier system with a fixed basic structure, a revolving traction means that is guided over pulleys, and
  • the workpiece carrier has load rollers, which on a The rolling surface of the basic frame runs and via which the weight of the workpiece carrier and a workpiece resting on the workpiece carrier is transferred to the basic frame. Furthermore, the workpiece carrier has a clamping device with clamping elements, between which the traction means is arranged and by means of which the workpiece carrier can be clamped to the traction means.
  • the feed and return sections of the traction mechanism each run in two horizontal planes.
  • workpiece carrier systems are also known in which the feed and return sections lie in a horizontal plane, i.e. are at the same height.
  • the system known from EP 1 999043 B1 is to be used as a workpiece carrier system with forward and reverse running in a horizontal plane, the construction is very complex, since the load rollers of the workpiece carriers are then no longer suitable to be transported component. Rather, an additional chassis would have to be installed, which would increase the complexity and space requirements.
  • the workpiece carrier system comprises a fixed basic frame, a driven, revolving traction means which is guided over at least two deflection rollers, and at least one workpiece carrier.
  • the workpiece carrier has load rollers and a clamping device.
  • the load rollers run on a rolling surface of the basic frame and the weight of the workpiece carrier and a workpiece resting on the workpiece carrier is transferred to the basic frame via the load rollers.
  • the clamping device has clamping elements, between which the traction means is arranged.
  • the workpiece carrier can be clamped to the traction means by means of the clamping device.
  • the axial direction of the pulleys runs orthogonally to the axial direction of the load rollers.
  • the orthogonal alignment of the axial direction of the deflection rollers to the axial direction of the load rollers ensures that even when the traction device is guided in a horizontal plane, the load rollers can transfer the weight of the workpiece carrier and a workpiece resting on the workpiece carrier to the basic structure. An additional undercarriage is not necessary and the design effort for the system is correspondingly low.
  • the axial direction of the deflection rollers runs in the vertical and the axial direction of the load rollers runs in the horizontal.
  • the clamping elements are arranged laterally on the traction means.
  • the vertical is understood here to mean the direction in which the weight force acts.
  • the horizontal is understood to mean the direction orthogonal to the direction in which the weight acts.
  • the deflection rollers are vertical and the load rollers are horizontal and the traction means can be clamped laterally (ie from both side surfaces) by at least one clamping element.
  • the traction means is guided in this way in a horizontal plane and at the same time from the left and clamped on the right.
  • the workpiece carrier can thus be easily detached from the traction means and then removed without removing an under-grip bolt or the like or without compressing the traction means.
  • the traction device is designed as a flat belt, it should be oriented in such a way that its flat side is oriented vertically.
  • the flat belt should stand vertically in order to be able to provide the clamping elements with a sufficiently large clamping surface.
  • the vertical alignment of the deflection roller axis described above is not mandatory.
  • the axial direction of the deflection rollers can be tilted at an angle to the vertical. This tilt angle should be ⁇ 45 °, preferably 5 ° to 20 °.
  • the workpiece carrier in this embodiment can have a workpiece holder which is also tilted by the tilt angle relative to the axis of the load rollers.
  • the workpiece holder can compensate for the inclined position of the deflection rollers or the load rollers, so that the transported workpiece is in a horizontal position.
  • the inclined position of the deflection roller axis ensures that the return and the forward travel of the traction mechanism are not in the same horizontal plane. In this way, even large workpieces can be transported with limited space.
  • the traction mechanism can be guided through a traction mechanism guide.
  • This traction means guide can be trapezoidal, in which a bead or thickening formed on the traction means is advantageously guided. In this way, for example, a lateral centering of the traction mechanism is possible.
  • the load rollers of the workpiece carrier can be designed as steerable rollers.
  • the workpiece carrier can be equipped with additional guide rollers. This ensures that the position of the workpiece carrier on the straight line and also in the deflection is guided in such a way that the traction device does not have to absorb any lateral forces.
  • the guide rollers are guided on guide webs formed on the basic framework or in a guide groove formed on the basic framework.
  • the clamping device of the workpiece carrier is used to achieve the frictional connection between the workpiece carrier and the traction means via a clamp.
  • the workpiece carrier has clamping elements, between which the traction means is arranged.
  • the workpiece carrier can be clamped to the traction means by means of these clamping elements of the workpiece carrier.
  • the clamping device moves completely with the workpiece carrier, so that no wear occurs during normal operation.
  • the clamping device is dimensioned in such a way that the clamping force is sufficiently great that the traction means can take the workpiece carrier with it.
  • the workpiece carrier can have at least one spring element which exerts a spring force or magnetic force on at least one clamping element and thus effects the clamping.
  • a clamping element can comprise a rotatable eccentric element which, in particular, is rounded
  • the use of an eccentric element enables the clamping of the workpiece carrier to the traction mechanism to be opened and closed without jolting.
  • a steady increase in the clamping force can be achieved when clamping.
  • the spring element can also attach to the eccentric element in such a way that the spring force causes the eccentric element to rotate in such a direction that the clamping force is increased.
  • a bolt or a fold arranged on the other side of the tension member can be used as a counter-clamping element.
  • the workpiece carrier can have an actuating element in the front area in the direction of travel, which reduces the clamping force in the event that the workpiece carrier runs into a preceding workpiece carrier by actuating it.
  • each workpiece carrier can have an actuating plunger at the rear, which acts on the actuator or directly on the clamping element and releases the clamping element.
  • the actuating element can have an actuating head which, in the event of the workpiece carrier running into a preceding workpiece carrier, runs against a contact surface of the preceding workpiece carrier.
  • the actuating element can furthermore comprise a thrust device or some other force transmission, at one end of which the actuating head is arranged and which, in particular, attaches to the eccentric element at its other end.
  • the clamping can be released in the event of a traffic jam. Due to the reaction force of the actuating element (clamp actuator), the front workpiece carrier is pushed further in the conveying direction / pulling direction and its clamping is thereby further released until it is fully opened. As a result, the penultimate workpiece carrier and the workpiece carriers in front of it no longer have any feed force. This means that a stopper can also hold up a large number of tool carriers without accumulating the accumulating forces.
  • the guide roller (s) and / or the clamping device are preferably arranged on the longitudinal axis of the workpiece carrier.
  • the longitudinal axis of the workpiece carrier is understood here to mean the center of gravity axis in the longitudinal direction of the workpiece carrier.
  • the clamping elements are arranged in the vertical direction below the guide roller or below the guide webs formed on the basic frame. This makes it possible to implement the workpiece carrier without changing the deflection radii on the drive station. In this way, different deflection radii can be produced without adapting the guide webs during the transition from straight to circular movement.
  • the belt is preferably clamped either with an eccentric and a counter retaining bolt or by two symmetrical clamping jaws.
  • clamping jaws are moved via a clamping actuation and thus opened or closed.
  • the clamping jaws are compressed by means of a leg spring and pushed apart by the clamping actuator against the spring force when the actuating bolt hits a stopper or the workpiece carrier that is moving in front pushes this clamping actuator in.
  • Another advantage of this configuration is that neither the center distance nor the direction of the curve influence the position of the guideways.
  • the workpiece carriers must be stopped at the stations of the workpiece carrier system.
  • at least one stop device which comprises a stop element
  • the workpiece carrier can have a release element which, when the release element runs against the stop element, interacts with the stop element in such a way that the clamping force is reduced and the workpiece carrier stops.
  • the stop element can be arranged displaceably or pivotably in such a way that it can be transferred from a position in which the stop element is in engagement with a disengagement element of a workpiece carrier into a position in which the stop element is not in engagement with the disengagement element, so that the workpiece carrier can be moved to the next station.
  • the release element can be connected to the thrust device. In this way, the thrust device causes a reduction in the clamping force both when running onto a preceding workpiece carrier and when stopping at a station.
