    Transport means, with at least one transport element and a drive system for the transport element
    The invention relates to a conveyor, with at least one transport element and a drive system for the transport element.
    An escalator or a moving walk include moving transport elements, usually made of metal and in the case of escalators forming their steps or forming a flat surface at a moving walkway. The transport elements are interconnected, which can be done indirectly via, for example, a drive chain. But the transport elements can also be directly connected to each other and thus form a chain itself. Furthermore, deflecting devices are provided at the two ends of the chain, if necessary also for the formation of shoulders between them.
    Conventional drive systems for such means of transport typically include a geared motor mounted in installation spaces at the top or bottom of the escalator and imparting a drive force to the drive chain or chain via a drive wheel engaged therewith. The drive wheel can also be part of one of the deflection at the same time. Such drive systems require a large installation space to accommodate all the necessary components of the drive, especially in conveyors that have to overcome either large height differences or long distances.
    It was therefore the object of the present invention to provide a means of transport with a smaller footprint.
    To achieve this object, the means of transport described above is characterized in that at least one linear drive is provided for the or each transport element, which indirectly or directly exerts a driving force on the means of transport in at least one working direction.
    According to an advantageous embodiment, it is provided that a plurality of separate transport elements, in particular stages ode. Segments of an escalator, a moving walk od. Like., Are coupled to each other to a chain, and that at least one linear drive in at least one working direction indirectly or directly exerts a driving force on the chain of the transport elements.
    A further embodiment of the invention is characterized in that a multiplicity of separate transport elements, in particular stages or segments of an escalator, moving walk or the like, are coupled to at least one drive chain and thus combined to form a chain, and in that at least one linear drive in at least one working direction 1
    KH-3406 AT a driving force on the drive chain and thus exerts indirectly on the chain of the transport elements.
    A very reliable and very suitable for large drive forces drive system is characterized in that the linear drive has at least one motor driven for rotation about an axis pulley with at least one spiral to the edge of the disc towards running guide, with which guide at least one with a transport element or the drive chain connected force transmission element cooperates, on which caused by the means of the transport element or the drive chain linear positive guidance in the course of rotation of the disc radially or tangentially to the axis of the disc force acting and thus further acting on the transport element or the drive chain force is generated , Such a drive allowed by the low slope of the guide, the transmission of large driving forces and yet provides the additional advantage of low construction height, since in principle no gear is necessary. The self-locking is another advantage of this type of drive.
    According to an advantageous embodiment of the invention it is provided that the disc has a plurality of movable segments, each segment being provided with a helically extending towards the edge of the disc guide, and wherein a mechanism is provided which is in a predetermined angular range about the axis of the disc each brings a segment into engagement with a power transmission element and moves the remaining, located outside the predetermined angular range of segments from the range of the power transmission elements. This ensures that the declining segments are not in engagement with a transport element or the drive chain.
    This "decoupling" each receding guide can also be achieved by an alternative embodiment in which the disc has a plurality of spirally extending towards the edge of the disc guides, and wherein the disc is placed against the track of the force transmission elements, so that at any time only one of the guides in Engagement with a power transmission element is. For particularly long chains of transport elements and / or very large loads, an embodiment is particularly advantageous in which a plurality of disks are provided along the path of the transport elements or along the drive chain, which can also transmit driving forces, for example.
    Bet of this embodiment of the invention, a further variant is very advantageous, which is characterized in that each disc on the path of the power transmission elements away or away, and that at any time at least one guide at least one disc with a power transmission element is in communication and at least another disc is moved away from the path of the power transmission elements. This is also 2
    KH-3406 AT
    Constructions possible, in which always at least one sub-segment or a disc engages in the chain of the transport elements or in the drive chain. It could also be realized with only one guide each disc.
    Favorable enough, the coming into contact with the guide areas of the power transmission elements with friction-reducing devices, such as rollers, rollers or ball bearings, od. Like. Provided.
    On the other hand, the regions of the guide which come into contact with the force transmission elements could also be provided with friction-reducing devices, for example rollers, roller bearings or ball bearings, or the like.
    In the following description, the invention will be explained with reference to the accompanying drawings.
    1 shows a plan view of a part of a linear-driven escalator according to a known embodiment, FIG. 2 is a side view of the section of the known escalator of FIG. 1, and FIGS. 3a and 3b show an embodiment of a pane according to the invention in the side view and the top view.
    The moving transport elements 1 in the form of steps of Fig. 1 are connected to form an escalator directly to each other and thus form a closed chain of transport elements 1, which is guided over deflectors, not shown.
    The transport elements 1 or their connecting parts have sliding elements or rollers 2 with which the transport elements are guided in a guide, on a rail or the like.
    On the chain of transport elements 1, a drive system with a driving force acts.
    As is known and illustrated in FIGS. 1 and 2, for example, a drive system with at least one, over a portion of the length of at least one chain center of the chain of transport elements 1 extending, motor-driven threaded spindle 3. At least some of the transport elements 1, preferably coaxially with the axes the rollers 2, pins 4 are provided which project outwardly and engage in the thread of the threaded spindle 3.
    The pins 4 could also emanate from a separately provided drive chain 5, via which the stairs are combined to form a chain of transport elements 1.
    The rollers 2 for the leadership of the stairs can be provided in this case on or in the drive chain 5. Upon rotation of the threaded spindle 3 is due to the positive guidance of the pin 4 parallel to the threaded spindle 3, a driving force on the pin 4 and thus further on the transport elements 1, possibly also by means of the separate drive chain 5, exercised. Furthermore, it would be possible to drive not a chain 5 but a rod 6 (FIG. 3), which is coupled to one or more of the transport elements 1, and which rod 6 are then provided as force transmission elements again pin 4. 3
    KH-3406 AT
    Such a rod 6 with pin 4 is shown in Fig. 3 in connection with the drive system according to the invention, in which the linear drive has at least one driven by a motor for rotation about an axis 7 disc 8. This disc 8 is substantially parallel to the rod 6 - or the chains of transport elements 1 or the drive chain 5 - oriented and has four spirally extending towards the edge of the disc 8 guides 9. These guides 9 may be designed as a groove-shaped groove in the surface of the disc 8, but may also be formed as a helical step or as a ridge on the surface or be realized by similar structures.
    With one of these guide 9 acts - realized here as the pin 4 of the rod 6 - power transmission element together by this example pin 4 rests on one side of the illustrated in the example of FIG. 3 as a step on the disc 8 guide 9. Due to the substantially rectilinear and oriented in the direction of movement of the transport elements 1 forced operation of the pin 4 is generated in the course of rotation of the disc 8 about its axis 7 by means of a drive mechanism, not shown, a substantially radial or tangential to the axis 7 of the disc 8 acting force and continue on the rod 6 or any drive chain 5 further transmitted to the transport element 1 or the chain of the transport elements 1. The drive, by which the disc 8 are rotated, may be a conventional drive, preferably an electric motor.
    Each of the four guides 9 of the disc 8 shown in Fig. 3 is located on a segment 10, wherein each of the segments 10 is movable independently of each other of the segments 10. In each case one of the segments 10, which is located in a predetermined angular range about the axis 7 of the disc 8, in which the guide 9 of this segment 10 can exert a driving force on the rod 6, engages with the mechanism Force transmission element 4 of the rod 6 bring. At the same time, however, this mechanism also ensures that all other segments 10 which are outside the predetermined angular range are moved away from the area of the force transmission elements 4. For this purpose, the segments 10 may for example be individually coupled in the direction of the axis 7 displaceable with the axis 7, but the segments 10 may also be pivotally mounted on the axis 7 and down. Furthermore, the guide 9 could also be brought out of engagement with the force transmission elements 4 or else engaged again by folding over the entire segment 10. So here are many possible embodiments within the scope of the invention.
    Another way to get this "decoupling" can accomplish each receding guide 9, in a disc 8 with a plurality of spirally extending towards the edge of the disc 8 guides 9 by an inclination of the disc 8 with respect to the path of the power transmission elements 4 and the path of the transport elements 1 or the drive chain 5 4th
    KH-3406 AT or rod 6 can be achieved. In principle, it would also be conceivable, by suitable deflection devices or mechanisms, to guide the force transmission elements 4 in a path which only brings them into contact with a respective guide 9 over a part of their path in the area of the disc 8 and otherwise of which only themselves a level rotating disc 8 lifts.
    As an alternative to the above-described guides 9, the disc 8 could also be provided with at least one rod-shaped or finger-shaped element which can be brought into engagement with at least one of the force transmission element 4 over a predetermined angular range about the axis 7 of the disc 8. This can be effected for example by a cam which moves concentrically to the disc 8 and the element always pushes radially outward in the predetermined angular range.
    In order to be able to cope with particularly long chains of transport elements 1 and / or very large loads, without coming to the limits of the breaking load of the chain or any drive chain 5, along the path of the transport elements 1 and along the drive chain 5 more discs 8 may be provided. These many discs 8 can simultaneously transfer their driving forces directly or indirectly to the chain of transport elements 1. In the case of a plurality of disks 8, however, each disk 8 can also be axially displaceable toward or away from the path of the force transmission elements 4, at least one guide 9 at least one disk 8 communicating with a force transmission element 4 at any one time. At least one further disc 8 can be displaced axially out of the path of the force transmission elements 4. As a further alternative possibility, at least one disc 8 move away from the path of the pin 4, a folding away of the disc 8 would be conceivable, for example by means of a swing or pivot mechanism.
    In this case, at least one segment 10 or a disc 8 can always engage in the chain of the transport elements 1 or in the drive chain 5, which also allows the execution of each disc 8 with only one guide 9.
    Advantageously, friction-reducing devices, such as rollers, roller or ball bearings, od. Like. Between guide 9 and pin 4 or other power transmission elements are provided, which means may be provided either on or in the guides 9 or to the power transmission elements 4. 5
