    Technical area
    The invention relates to a rope balancer according to the preamble of claim 1.
    State of the art
    A double rope balancer according to the prior art is described in DE 103 12 847 A1. There it is described how a winding cylinder is described inside a housing, which rotates and winds up the ropes of the rope balancer.
    Object of the invention
    The object of the present invention is to overcome the disadvantages of the prior art. In particular, a rope balancer should be provided in which the ropes should not get caught with each other or in the technology during the winding and unwinding of the page.
    Solution of the task
    [0004] The features according to claim 1 lead to the solution of the object.
    [0005] Advantageous configurations are described in the subclaims.
    A rope balancer according to the invention is used for the simple handling of one or more workpieces by a user. The workpiece is held at a certain working height by the rope balancer, while the user can move the workpiece back and forth at the working height level.
    For this purpose, the rope balancer consists of a housing. The housing has a connecting bracket. The housing essentially accommodates the technology used. The connection carrier is used to connect the housing, for example in a rail system or a bracket.
    The rope balancer according to the invention has a first rope and a second rope. But it is also conceivable that only a single rope is used. The ropes are plastic-coated rope.
    The housing can be made in different lengths. In this way, sides of different lengths can be used in order to adapt the functionality of the rope balancer according to the invention to different user requirements.
    The ropes end at one end in the housing and at the other end usually at a workpiece gripper. The workpiece gripper can be designed specifically for the user.
    The first rope is movable through a first rope outlet and the second rope through a second rope outlet from the housing and can be retracted into the housing.
    The invention consists in that a pulley system is arranged in the housing. In this way, it is possible in a simple manner, for example, to achieve a desired working height or to deliver a workpiece again. Overall, there are also fewer force peaks, which often require electrical drives or pneumatic drives that are designed accordingly. The use of the pulley system means that only slightly powerful drives or pneumatic pressure ratios and the associated stronger seal are required in order to haul in the ropes and, for example, pull up workpieces or hold them at a defined height.
    For this purpose, a first cable holder and a second cable holder are arranged longitudinally in each case in a first position in the housing. In this context, longitudinal means that in the first position the first cable holder is located at a first longitudinal end of the housing and the second cable holder is located at a second longitudinal end of the housing.
    The first cable holder has a first deflection pulley and the second cable holder has a second deflection pulley. The first deflection pulley is usually a plurality of first deflection pulleys arranged next to one another, which are arranged to rotate freely in the first cable holder. In a preferred exemplary embodiment, the group of the first deflecting pulleys is divided into first deflecting pulleys for the first rope and further first deflecting pulleys for the second rope. In the same way, the second deflection pulley is usually a plurality of second deflection pulleys arranged next to one another, which are arranged to rotate freely in the second cable holder. In a preferred exemplary embodiment, the group of the second deflection pulleys is divided into second deflection pulleys for the first rope and further second deflection pulleys for the second rope.
    The first cable holder is preferably arranged statically in the housing and the second cable holder is movably arranged in the housing. In this context, arranged movably means that the second cable holder can be moved back and forth to the first static cable holder. The second cable holder can be moved back and forth over a defined guide, or it can simply be designed freely in the housing without a guide. In another exemplary embodiment, both rope holders can also be arranged to be freely movable.
    In a preferred embodiment, the second cable holder is pneumatically controllable towards the first cable holder and away from the first cable holder by a pressure source. For this purpose, an interior of the housing is pressure-tight. By means of compressed air, which is brought into the interior of the housing, the second cable holder is pressed in the direction of the first cable holder and by drawing off the air at defined points, the second holder is pulled away from the first cable holder.
    The first rope outlet comprises a first rope outlet seal and the second rope outlet comprises a second rope outlet seal. The cable outlet seals can be arranged directly on the edge of the housing or at a depth of several millimeters or centimeters. It is preferably a double-lipped O-ring. But in principle there can also be other forms of seals.
    The second cable holder has a cable holder seal. This cable support seal is used to create a controllable atmosphere on the one hand between the first cable support and the second cable support and on the other hand between the second cable support and a rear wall of the housing, from which the second cable support can move to the first cable support and back.
    The first rope holder has a buffer receptacle on the side facing the second rope holder, and the second rope holder in turn has a buffer on the side facing the first rope holder. In this way, the components are prevented from getting caught in one another and uncontrolled collision between the second cable holder and the first cable holder is also prevented.
    In an installed state, the housing has a pressure inlet / pressure outlet, the pressure inlet / pressure outlet acting on the side of the second rope holder facing away from the first rope holder or generating a negative pressure. When there is overpressure, the second rope holder is pressed towards the first rope holder, and when there is negative pressure, the second rope holder is removed from the first rope holder.
    In another example of an installed state, the housing has the pressure inlet / pressure outlet in such a way that the pressure inlet / pressure outlet acts on the side of the second rope holder facing the first rope holder or generates a negative pressure. In this case, either a negative pressure or an overpressure is generated between the first cable holder and the second cable holder. In the event of a negative pressure, the second cable holder is pulled towards the first cable holder, and in the event of an overpressure, the second cable holder is pushed away from the first cable holder.
    By changing the distance between the first rope holder and the second rope holder, the ropes are either further left out of the housing or drawn more into the housing.
