Definitions
- the invention relates to a device for transferring workpieces through a sequence of processing stations of a press, a simulator or the like processing or setting machine according to the kind defined in the preamble of claim 1.
- Such transfer devices are used in presses, step presses, press lines, but also in simulators for moving workpieces, in the latter application for setting up a press.
- a device in which the movement of the transport rails in their longitudinal direction is effected by at least one motor, which, directly when using a gear, indirectly on a gearwheel, when using a toothed belt on a deflection wheel, acts, the gear with a rack extending in the longitudinal direction of the transport rail, the deflection wheel cooperates with a toothed belt extending in the longitudinal direction of the transport rail, a tap point being formed on the toothed rack or on the toothed belt in a region remote from the transport rails, in which a coupling rod is articulated with one end part, the other end part being connected to the transport rail is articulated.
- a disadvantage of the device disclosed in the cited publication is that the different movements of the transport rails are mechanically coupled, which means that the entire device has to be assembled in a relatively complex manner and has a relatively large number of moving masses.
- the drive devices for the individual directions of movement of the transport rails are electrically coupled to one another, which eliminates the complex mechanical coupling.
- cross drives which move the cross beams, on which the drive devices for the longitudinal movement of the transport rails are arranged, towards one another in synchronism with the drive motor arranged in a lock box of the press for the horizontal movement of the transport rails, so that the cross beam is tilted in their Guide rails is excluded.
- the drive devices cannot be connected to the transport rails via simple coupling elements, such as rods, because otherwise the coupling elements will tilt or become tense and very high stresses will occur in the material of the coupling elements, which may even destroy the coupling elements being able to lead.
- the present invention is therefore based on the object of providing a device for transferring workpieces through a series of processing stations of a press, a simulator or the like processing or setting machine, which avoids the disadvantages of the prior art described, in particular with the problem-free connection of the Drive motors to the transport rails is possible.
- a press or a simulator 1 which has transport rails 2, which are movable in three mutually perpendicular axis directions.
- the direction of passage of workpieces through the press 1 is indicated by an arrow.
- gripping devices 3 known type are attached, for. B. pliers, suction cups or the like.
- the longitudinal movements of the transport rails 2 are carried out by drive devices 5, which move carriages 6, which can be displaced in linear guides parallel to the direction of passage.
- movable cross members 7 are arranged, which are connected to the transport rails 2 via suitable devices described below.
- the cross members 7 are supported in linear guides 8.
- the traverses 7 are moved by an additional transverse drive 9 synchronously with the movement of the transport rails 2.
- a connection between the traverses 7 and the transport rails 2 takes place via compensating guides 10 which are shown schematically in FIG. 1 and which are shown in more detail in FIGS. 2 and 3.
- Each individual compensation guide has two struts 11, 12, each of which on the one hand on the traverse side, i.e. on the side facing the traverse 7, has an upper articulation point 15 and a lower articulation point 16 with the cross member 7 and, on the other hand, via articulation points 17, 18 with a triangular shape double-arm bracket 13 are articulated, as shown in FIGS. 2 and 3.
- the double-arm bracket 13 in turn is provided at one end with a third articulation point 19 and is connected in an articulated manner to the transport rail 2 via a bolt 14.
- a compensation guide is realized by the arrangement described, by means of which tilting or bracing of the transport rails 2 and / or the crossmember 7 is avoided.
- a double-armed tab 13 is provided on the side of each individual transport rail 2.
- FIG. 4 A second embodiment of a compensation guide is shown in Figs. 4 and 5. Reference symbols already introduced in connection with the description of the preceding figures are to be used below for the same components.
- a straight flap 20 is used, at the ends of which the struts 11 and 12 are articulated at the articulation points 17, 18, while the ends of the struts 11 and 12 facing away from the transport rails 2 are via the upper articulation point 15 and the lower pivot point 16 are articulated to the cross member 7.
- the straight tab 20 itself is connected in an articulated manner to the transport rail 2 via the third articulation point 19.
- the struts 11, 12 are arranged crossing one another, i.e. the strut 11 is connected on the one hand to the upper articulation point 17 of the straight link 20 and on the other hand to the lower articulation point 16 on the cross member 7, while the other strut 12 is articulated to the lower articulation point 18 of the link 20 and to the upper articulation point 15 of the cross member 7 is.
- the movement of the transport rails on a straight line or in a linear manner can be implemented in a simple manner, but tensioning or tilting of the transport rails is excluded.
