Definitions

  • the invention relates to a feed device for step-by-step material and / or workpiece transport, in particular in presses, with two gripper rails which extend along the transport path at a distance from one another, in the feed direction to and fro and can be moved transversely in opposite directions, by means of a transverse drive driven in opposite directions and fixed in the feed direction, but transverse to the latter, connected to a feed carriage which is guided in the feed direction and by means of a feed drive with a belt drive which can be moved back and forth via deflection rollers arranged at a distance from one another.
  • a feed device of the aforementioned type for workpieces to be moved forward in batches which has two gripper rails which can be moved back and forth together as well as transversely in opposite directions.
  • the feed drive for the generation of the reciprocating feed movements of the gripper rails comprises two belt drives which are driven in opposite directions by a crank via intermediate gearwheels and act directly on said rail via drivers guided in longitudinal slots of a vertically movable rail and thereby translate it up and down .
  • vertically movably guided racks are connected on both sides of the guides Convert the downward movements of the rail into horizontal, back and forth feed movements of the gripper rails.
  • the previously known feed drive which is intended in particular for use in step presses, requires a complicated drive mechanism with two oppositely driven belt drives and a large number of transmission elements, each with a directional deflection of the movement produced, which is very complex in construction and only one in view of the large number of transmission elements and directional diversions allows limited accuracy of transmission of the drive movements.
  • feed devices from US Pat. No. 3,011,464 and DE-OS 22 06 407 in which the gripper rails, which extend along the transport path at a distance from one another, are driven both in the feed direction and transversely thereto by means of rotating cams and suitable transmission elements are.
  • feed devices are also extremely complex. Since the working strokes are fixed in the respective direction of movement with the dimensioning of the drive cam disks, adaptability to changed operating conditions is moreover not possible or only possible with relatively great effort.
  • the object on which the invention is based is to provide a feed device for step-by-step material and / or workpiece transport which is simple in construction and which is inexpensive in comparison to the previously known devices of this type and which is intended in particular for use in presses, but is not limited to this application.
  • the belt drive extends in the feed direction under the feed slide and has a toothed belt, the belt section of which is directly connected to the feed slide.
  • the invention thus realizes an extremely simple construction of the feed drive.
  • An embodiment of the feed drive according to the invention provides that the toothed belt is guided on deflection rollers with axes of rotation extending approximately at right angles to the feed direction and approximately parallel to the feed axis of the feed slide, and that the upper belt section of the toothed belt is connected to the feed slide.
  • the feed drive comprises two belt drives arranged at a distance from one another transversely to the feed direction, each with a toothed belt which is fixedly connected to the feed carriage by a belt.
  • the axes of rotation extending at right angles to the feed direction of the deflection pulleys which guide the two toothed belts of the belt drives on one side in each case can be aligned, in which case the deflection pulleys which guide the two toothed belts on each side of the belt drives can also be accommodated on a common shaft can.
  • the guide rollers guiding the two toothed belts on one side of the belt drives are driven by a motor which is arranged between the said guide rollers.
  • This drive motor can be a known stepping motor which can be reversed with regard to its direction of rotation or, for example, a motor with quadrant control. Instead of such an electric motor, a reversible hydraulic motor can also be used.
  • the transverse drive for generating the opposing gripping and opening movements of the gripper rails has a belt drive with a toothed belt which is guided over two spaced-apart deflection rollers and extends in the direction of the gripper rail transverse movement, the belt section of which has a belt in the direction of the Transverse movement of the gripper rails and is operatively connected to the latter is coupled.
  • the belt drive mediating the transverse drive extends below the guide plane of the gripper rails and one of the belt sections of the toothed belt is directly connected to a transverse longitudinal guide of the one gripper rails as a transmission element.
  • the belt section of the toothed belt which is fixedly connected to the transverse longitudinal guide of the gripper rail is advantageously the upper toothed belt belt section, while the lower belt section is connected to a slide which is movably guided transversely to the feed direction and in turn is coupled to a longitudinal guide of the other gripper rail.
  • the operative connection between the one belt section of the toothed belt and the transmission element consists of a retensionable turnbuckle, this turnbuckle having at least one threaded bolt screwed into a threaded hole of a driver section of the transmission element.
  • this transmission element can in the case of the feed drive back to the in feed direction and movable back out feed slide act, in the case of transverse drive the other hand, to the transversely movable longitudinal guide of the gripper rail or near one of these County s Inserten g- and coupled one with a Trumlage of the associated toothed belt Slider, which in turn is firmly coupled to the longitudinal guide of the other gripper rail in the direction of the gripper rail transverse movement.
  • two gripper rails 11, 12 extend along the feed path, for example through a press, at a distance from one another, which in turn are accommodated in longitudinally driven longitudinal guides 13, 14 in a manner to be described below and with a feed slide in the feed direction are fixed, but are coupled transversely.
  • the feed carriage is guided in the feed direction by means of two rod guides 16, 17, which extend at a distance from one another in the direction of the gripper rails 11, 12 and underneath them, and guide bushings 18, 19 received on these.
  • the feed carriage 15 is driven by means of two belt drives 20, 21, each with a toothed belt 26, 27 guided over deflection rollers 22, 23 and 24, 25, the axes of rotation of which run at right angles to the feed direction, which extend in the feed direction.
  • These belt drives are arranged in the area between the two guide rods 16, 17 for guiding the feed carriage 15 and the respective upper run of the two toothed belts 26, 27 is via two turnbuckles 28, 29 and 30, 31 with a connecting section 32 which extends from the feed carriage on the underside coupled.
  • each turnbuckle a section of the toothed belt is held by clamping in a manner of no further interest here, and a threaded bolt 33 extends on the side remote from the toothed belt, which is screwed into a corresponding threaded hole 24 of the connecting section 32 by the feed slide. It can be seen that the toothed belt can be tensioned by screwing the threaded bolts more or less deeply into the receiving hole of the connecting section.
  • the two guide rollers guiding the toothed belts 26, 27 are on one side of the feed carriage 15 waves 36, 37 and 38, 39 aligned with one another.
  • An electric motor 40 which generates the forward and return movements of the feed carriage 15 and thus also the gripper rails 11, 12 is arranged between the shafts 36, 38.
  • the coupling of the gripper rails 11, 12 to the feed slide 15, which is fixed in the feed direction but movable transversely to the feed direction, consists of drivers 41, 42 arranged on the underside of the gripper rails, which engage in a top-side groove 43 of the feed slide 15 which extends transversely to the feed direction.
  • Fig. 4 shows the formation of a transverse guide unit 45 with the two spaced-apart and in the longitudinally movably guided longitudinal guides 13, 14 received gripper rails 11, 12.
  • the longitudinal guides for the gripper rails are in turn arranged on guide plates 46, 47 which are transverse to Feed direction are movably guided in corresponding guides 48 of the transverse guide unit.
  • a belt drive 50 which extends transversely to the feed direction and has a toothed belt 53 which is guided over two deflection rollers 51, 52 arranged at a distance from one another and whose axes of rotation extend in the feed direction, the upper belt position of which was explained in connection with FIG.
  • the upper and lower run of the toothed belt 53 perform opposite movements, in terms of amount, which, in view of the coupling of these runs to the one gripper rail longitudinal guide
  • Transverse guide plate 47 on the one hand and the slide 60 connected to the transverse guide plate 46 of the other gripper rail longitudinal guide on the other hand are transferred to the gripper rails 11, 12 and are independent of the common forward and return movements of the gripper rails in the feed direction.
