Definitions
- the present invention relates to an apparatus for the handling of loads.
- This type of apparatus is generally used to lift and move loads within the limits of a predetermined space e.g. at a mechanical component assembly station on a production line, or at a distribution point for products or for semi-finished products which must be sent to other work-stations for further operations to be carried out on them.
- Devices known to the prior art comprise substantially a means for gripping or holding the load, at least one load counter-balancing device and means of measuring the weight of the load.
- a commercial balancer can be used with its cable or rope (or cables or ropes) acting on said first arm at a point between the hinging point of the arm to the support structure and the means for gripping or handling the load, or in a point placed on an arm portion extending from the hinge point in a direction opposite to that of the load.
- the device can operate taking into account not only the actual weight of the load but also the frictional forces between the various moving surfaces in mutual contact, and the apparatus may further comprise means of controlling the weight balancer automatically as a function of the weight of the load and the forces applied to it. In this way the power delivered by the balancer is controlled in real-time as a means of assisting the movement imparted by the operative.
- an apparatus 1 comprising a support structure 2, which can be mounted on a fixed vertical support 2a or on a support longitudinally movable along a rail (not shown), and means 3 of gripping a load by an operative.
- the means 3 are represented by a platform with handles 4 , but it is to be understood that said means may include any form which is found suitable to sustain the load, e.g. another frame to maintain a component in a particular position, or a hook.
- the structure 2 carries a second arm 5 which is rotatable in a horizontal plane about the axis A and carries a depending plate 6 to which a first arm 7 is hinged at 8 to be able to swing in a vertical plane.
- the other end of said first arm 7 is hinged, at 9, to a plate 10 carrying a load gripping and holding means, in the form of a rotatable supporting element 11 and said platform 3.
- the arm 7 is twinned by another reinforcing arm 12 to set up a parallel structure in which the arm 12 is hinged at 13 to the plate 6 and at 14 to said plate 10, in order to control the movements of the load gripping or handling means 3, 11 in a vertical plane so that said means 3, 11 always remains parallel to itself.
- Fig. 1 the positions of arm 7, 12 are also represented by dotted lines in the minimum and maximum elevations of the load.
- a zero-gravity balancer 15 (in this embodiment a commercial zero-gravity balancer) is mounted on the support structure 12, for instance on the side thereof opposite to that of the arms 7, 12.
- the balancer 15 usually operates by means of a cable or rope or a plurality of cables or ropes 16 to the end of which the load to be balanced is attached.
- the cable or rope 16 passes over two freely rotatable pulleys 17 and 18, and is attached to a chosen point 19 along the extension of arm 7. More detailedly, the second arm 5 carries a support for the pulley 18 so that said pulley 18 and the point 19 are substantially aligned.
- the zero-gravity balancer 15 can be of a commercial type, with given ranges of load capacity, lifting speed and stroke, it is possible to conform the balancer 15 with the required load weight and operating features of the apparatus by simply choosing the point 19 of attachment for the end of cable(s) or rope(s) 16 along the arm 7. Between the rope end and the arm attaching point 19, a conventional stroke reducer 20 can be placed. In this way, by simply varying the attaching point 19 (and if appropriate the horizontal position of pulley 18) it is possible to cover with a single balancer 15 very wide ranges of load weights and working requirements of the apparatus.
- the balancer may be of the known type in which the (load) weight is pre-set, or of the self-balancing type, for instance by means of a load cell 21.
- FIG 3 shows another embodiment of the present invention, wherein the same references indicate similar components to those of Figures 1 and 2.
- the arms 7 and 12 are directly hinged to the support structure 2 which is rotatably mounted on its base 2a.
- Arm 7 has an extension 7a in a direction opposite to that of the load and the attaching point 19 for the rope 16 of balancer 15 is provided at a suitably chosen point along this arm extension 7a.
- the balancer 15 is fixedly mounted on the structure 2 and the rope 16 may reach the attaching point 19 directly or after passing on a free pulley 22 mounted on an arm 23.
- the present invention encompasses apparatus and designs thereof in which the position of the rope or cable attachment point and the positions of the balancer are defined during design of the apparatus to meet particular operating requirements. This permits a basic design to be used for a variety of applications simply by varying one or both of the positions defined above. The apparatus is then constructed according to the design with the above positions predetermined.
- the invention also encompasses apparatus and designs in which a plurality of attachment positions of the rope/cable and/or of the balancer may be pre-defined, and an individual apparatus can be configured or re-configured to suit immediate operating requirements.
