    The invention relates to a device for manipulating loads, with a vacuum lifter, with a control for actuating a lifter, with at least one arranged on a support body, suction lips having suction, in particular a suction cup, and with a Saugerbetätigung.
    Such vacuum lifters are used to manipulate various loads od with suction plates. Like. Can be safely gripped and lifted, such as glasses, windows, body parts, metal parts and much more. Currently common vacuum lifter are hooked with the support frame in the hook of a hoist, especially a crane, and raised and moved with this. The hoist is controlled by means of a pendant button. The control of the vacuum suction is arranged on the support frame.
    The problem with the current solutions in particular that the load can be raised and manipulated even if it is not ensured that it is also held securely by the suckers, which is a significant security risk. Since there can be no information as to how heavy the load attached to the lifting device is and in fact to be lifted, or whether the load is securely struck, it is also not possible to control the lifting device on a load-related basis. Critical situations also arise in particular if, due to the placement of the suction cups on particularly smooth surfaces, such as glass, by the sealing of the suction lips, there is an intrinsic vacuum, which applies a certain but insufficient holding force and entices the operator to do so to raise the goods without first od the vacuum generating pump. Like. Turn on. This results in the loss of the load, because the self-vacuum created as a holding force is usually insufficient and, in addition to the damage or destruction of the falling load, a considerable risk of injury. In addition, the release of the load in the known devices is practically possible in any manipulation position with an unwanted manual actuation of a button or lever, whereupon the load (glass, metal, etc.) in turn whether the dissolution process is actually wanted or whether this consequence of a Misoperation is unsecured from the teat drops or slips off.
    The invention has for its object to provide a device of the type described, which meets increased safety standards. In particular, an unintentional release of the load from at least one sucker and thus the risk of accident due to incorrect operation and possibly uncontrolled movements should be excluded as far as possible.
    The invention solves this problem in that a common load-dependent control for the operation of the lifter and the Saugerbetätigung is provided. According to the invention, the control of the lifter is connected to the control of the nipple or the teat to a common control, wherein the controls for the lifter, in particular a chain or cable, and the operating elements of the teat are preferably provided on a common console. This allows the lifter to be precisely controlled. A lifting of the load takes place only if it was previously properly absorbed with the nipple.
    According to a development of the invention, a load sensor assigned to the lifting device is provided for load measurement, which is arranged in series with the hoisting device comprising a chain or cable pull. Thus it can be determined at any time, whether the holding force of the vacuum cleaner is sufficient and whether a manipulation of the load is possible without hesitation. There is always a load query, which together with the prevailing at the suction pressure ratios allows unambiguous conclusions on the holding security of the device.
    For this purpose, it is recommended that the vacuum cleaner is associated with at least one pressure sensor, which receives the pressure prevailing in the suction cup and directs it to the controller. The lifting device for manipulating the load is released when lifting the load only after the sucker operation, in particular from reaching a preferably load-dependent, at least necessary negative pressure in the suction plates, from the controller. Likewise, when a load is turned off, the vacuum can only be released by the controller after the load has been released from the weight of the load, in particular from a drop below a load picked up by the load sensor.
    All safety-relevant processes are then made dependent on the weight and the prevailing pressure conditions. Before executing individual control commands, a computer, in particular a PLC, checks whether the respective command switched by an operator can also be executed safely, otherwise safety-critical commands are not accepted at all and an optical and / or acoustic warning is issued. To settle the parts on the ground, it is checked via PLC whether the lifting device is load-free, otherwise the load can not be released. Hub speeds can be regulated depending on the actual load. Lifting operations when the negative pressure is switched off or insufficient can be stopped immediately and thus prevented.
    In order to ensure safe and rapid trapping of the load, the at least one sucker may be associated with an approach sensor which detects an approach to a load to be picked up, the control releasing the negative pressure buildup in the sucker as it approaches the load to be picked up.
    In addition, the at least one sucker can be arranged on a support frame, which is pivotable about at least one axis relative to the support body, preferably lastab-4/20 4. the control of the associated Verschwenkeinrich device can in turn be load-dependent. For example, horizontally suspended plate-shaped loads may have different maximum weights than vertical ones. To release the properly parked load the sucker can be assigned a repelling device for releasing the load from the sucker. For the sake of simplicity, a vacuum pump, in particular a compressed-air-controlled cylinder unit, is provided for the vacuum build-up, wherein a valve is preferably provided in the vacuum line leading to the at least one sucker. A simple and safe handling of the device is ensured when the carrier is provided on the side facing away from the load receiving a control elements carrying actuator. A particularly secure hold of the load can be ensured if the suction plate has at least two suction lips circulating around the suction plate edge parallel to one another and / or if the control reduces the speed of manipulation with increasing load.

    A device according to the invention for manipulating loads 1, in the illustrated example plates or glass panes, comprises a vacuum lifter 2, a control 3 for actuating a lifting device 4, at least one suction device 7, in particular a suction plate, arranged on a supporting body 5 and having a suction lip 6 a Saugerbetätigung 8. According to the invention a common load-dependent control 3 is provided for the operation of the lifter and the Saugerbetätigung. The provided in a housing and only hinted control 5 can be arranged naturally 3 at any point of the device, as well as the Saugerbetätigung 8, which is indicated as part of a manual actuator, and in particular in the same housing as the controller 3 can be arranged.
    To measure the respectively recorded by the device and to be supported by the suckers 7 load 1 is the lifter 4, a load sensor 9, a load cell od. The like., Assigned to the chain hoist 10 comprehensive lifting device 4 is arranged in series. In the present example, the chain 10 is struck by the load sensor 9 on the support body 5.
    At least one pressure sensor 11, which receives the pressure prevailing in the suction plate and conducts it to the controller 3, is assigned to the vacuum cleaner 7. It can thus be ensured that the load can not be lifted until a sufficient holding force has been built up in the suckers 7. For this purpose, the lifter 4 for manipulating the load 1 is released by the controller 3 only after the sucker operation, in particular from reaching a preferably load-dependent, at least necessary Un-terdruckes in the suction plates. In the same way, the sucker 7 is only after the load release from the weight of the load 1, in particular from a fall below a recorded by the load sensor 9 load 1, from the controller 3 freigebar. This ensures that no floating and sufficiently supported or secured loads can be released from the suction cups.
    In order to ensure rapid and safe capture of the load to be absorbed, at least one sucker 7 may be associated with an approach sensor 12 approaching a load to be picked up, the controller 3 releasing the vacuum buildup in the sucker 7 as it approaches the load being picked up. If a sufficient approximation of the sucker 7 is given to the load, for example, a vacuum pump is activated and the load caught gently. The proximity sensor 12 may be, for example, an ultrasonic sensor or the like. 6/20 6
    If the at least one sucker 7 is arranged on a support frame 13 which is pivotable about at least one axis 14 relative to the support body 5, preferably load-dependent, the load can not only be lifted and displaced but also displaced about horizontal and / or vertical axes be, with which, for example, lying recorded loads 1 standing can be turned off. In order to avoid an unwanted release of the load 1 from the suckers 7, the controller can reduce the speed of manipulation with increasing load. A quick and easy release of the load 1 from the device can be made possible by the fact that the teat 7 is assigned a repelling device 15 for releasing the load from the teat 7. The repelling device 15 may comprise separate Abstoßer or be designed such that the suction cups are acted upon for pushing with overpressure.
    Simple construction conditions arise when a compressed air-controlled cylinder unit is provided for the vacuum build-up, wherein in the leading to the at least one vacuum line vacuum line 16 is preferably a valve 17 is provided. A control elements supporting manual actuator 18 is assigned to the carrier on the side facing away from the load bearing. 7.20
