Definitions

• the present invention relates to a method and an exemplary device for the particularly rotating transport of components or tools along a chain or belt track.
• Feed movement During transport, it must be taken into account that the components only come into contact with the transport device or the component carriers at certain points.
• Mandrels, internal chucks or similar clamping elements are firmly or detachably integrated.
• the component carriers are rotatably mounted in the chain and have at least one sprocket with which they are set in rotation by means of a drive chain. If the component carriers have to be exchangeable, a mounted sleeve with an additional coupling point and fixing device is inserted into the pivot point of the chain instead of the rotatably mounted mandrel.
• the known solutions are inflexible due to this construction and the transport method specified with it and do not allow different distances between the workpieces and thus also no different dwell times in the continuous ovens and cooling sections.
• the well-known Functionality allows only one continuous chain per system and thus prevents or complicates a possible modular structure of these systems. Resin vapors and resin droplets are also particularly problematic for bearings and coupling points and lead to failures. In addition, the construction effort of the massive chain is considerable.
• Publication JP 2000-117640 A presents a transport system for round components in which the components can be transported linearly with a given rotation.
• the aim of the invention is therefore to create a flexible transport system that allows both gradual and continuous transport in both directions and is independent of speed and direction of rotation. Furthermore, the new system should have no bearings between the chain and the mandrel and components without them
• the distances between the mandrels should be flexible and can be adapted to the component sizes.
• the transport system should be modular, which means that the transfer of the component carriers and thus the components from the transport chain of one system part to the transport chain of another should be possible with continuous rotation.
• the component carrier usually a clamping or fixing device for stators and rotors of electric motors, is rigid with two
• the component carrier is transported with the two chain wheels without rotation in the respective direction of movement of the chain.
• the component carrier rotates without leaving its position.
• the direction of rotation can be reversed by reversing the chain movement direction.
• Transport speeds can therefore be changed at any time.
• the component carrier does not require a warehouse for transport or rotation.
• the sprockets themselves are drive and storage at the same time.
• the new process also allows component carriers with workpiece to be moved in and out without a coupling point, for example by changing the distance between the upper and lower chains. Since the rotating component carriers are not firmly integrated into the chains as in previous solutions, the distances from Component carrier to component carrier can be changed as required, taking into account the workpiece and sprocket size. Adapting to different
• the proposed method with the corresponding structure also enables rotating component carriers with components to be transferred from one chain drive to another without interrupting the rotation, and thus entire transport systems
• Transport device for the rotating workpieces can have.
• the device for implementing the method is based on chains and
• the sprockets of the component carriers run in the middle chain row and the drive sprockets and the deflection sprockets as
• the chain rollers on the outer chain rows can alternatively also be used for force application
• Deflection radii and guide strips are used. If only narrow connecting links are used on the outside of the chain, the rollers of the outer tracks serve as bearings for guiding the chain, for example in guide rails.
• the division of the tracks means that there is no mutual interference between the fixed drive and guide elements and the mobile component carriers.
• the inner chains can be guided through chain wheels and the outer ones through guide strips with a corresponding radius.
• the double chain wheels should be selected as small as possible so that the chain wheels of the component carrier always remain in mesh. It is also proposed the transition from upper chain to upper chain and from lower chain to lower chain in order to offset the transition width. In addition, it is advisable to install wear strips at the transition, which ensure the position of the component carrier between the chains also at the transition.
• the upper and lower chains are driven separately.
• the drives are preferably located at the end of the conveyor line.
• Chain tensioners are proposed that act in pairs on the slack part of the chain.
• the component carrier preferably consists of a tube on which two chain wheels are fixed on the outside at a suitable distance. Inside is a one-sided projecting one
• the component carrier is fixed, which leads to a more even load on the component carrier and the chains and doubles the transport capacity.
• the proposed method and the device can also be used with a single-track roller chain, with round steel chains and with belts, in particular
• pocket wheels are used as drive and deflection wheels, while wheels are placed on the component carrier that engage in the links of the round steel chain.
• At least individual component carriers can be equipped with tools such as brushes, grinding elements or nozzles and, due to the possible rotary drive, perform work along the route.
• a component can be brushed at the same time as it is being heated in the conveyor oven.
• the component carrier itself can also be designed as a tool.
• FIG 2 shows a simplified transport system in side view
• FIG. 3 shows an exemplary component carrier with an attached component
• Fixing device moved continuously or step by step from one station to another and set in rotation by an additional chain drive.
• the new method enables a variable number of component carriers 2 to be picked up, transported and driven by two separately driven pairs of chains, two upper chains 6 on one side of the sprockets 3 and two lower chains 7 on the other. This only works because a variable distance between the component carriers 2 is possible.
• the upper chain 6 and the lower chain 7 move in the same direction and at the same speed. This results in the component carrier 2 being transported without rotation in the direction of movement of the chains at chain speed.
• the upper chain 6 and the lower chain 7 move in opposite directions at the same speed. This results in a pure rotation of the component carrier 2 without further transport of the component carrier 2.
• the upper chain 6 and the lower chain 7 move in opposite directions at different speeds.
• the transport speed of the component carrier 2 results from the speed difference.
• the direction of movement results from the direction of movement and whether the upper chain 6 or the lower chain 7 runs faster. From the speed of the slower chain it follows depending on
• the diameter of the sprocket 3 on the component carrier 2 is the speed and the direction of rotation from the direction of movement.
• the speed difference results from the speed difference as a function of the diameter of the chain wheel 3 on the component carrier 2.
• the direction of movement of the component carrier 2 results from the direction of movement of the chains.
• the speed of the component carrier 2 results from the

• Handling devices such as robots over various system parts or
• a modular structure of a system with chain conveyor with continuously rotating components or tools is possible.
• Slightly inclined position of the component carrier 2 can be achieved permanently by offset tooth alignment of the two chain wheels 3 on the component carrier 2, temporarily this is possible by slightly shifting the rear upper chain 6 and lower chain 7 relative to the front chains.
• the rear chains can be raised and the front chains lowered accordingly.
• the smooth transition can be an offset of the transition between the upper chains 6 to the Lower chains 7 and / or the additional introduction of slide strips 9, the
