Definitions
- the invention relates to a device for the gradual displacement of workpieces, in particular within a press, with at least one or two gripper parts or gripping areas that can be moved back and forth in the feed direction for the feed and return movement for gripping the gripper rail (s) that have workpieces and that are used for gripping the workpieces and for moving in the feed direction can then be adjusted again in the starting position, with at least two levers which can be pivoted on the gripper rail (s) parallel or mirror-synchronously to one another in the plane of movement, in a plane parallel thereto or in a plane oblique thereto, and in the case of a device with two parallel gripper rails, these levers of one gripper rail can be pivoted in the opposite direction to those of the other gripper rail.
- Such an apparatus having two parallel gripper rails is known from DE 102 06 773 C1, wherein further in this document prior art is cited regarding such gripper rails'.
- This device has proven itself particularly in those presses in which the gripper rails between the press stands are arranged so that they protrude in their longitudinal direction and in the feed direction of the workpieces. It is favorable here that only the gripper rails and the workpieces grasped by them, as well as grippers or gripper parts, that is to say relatively small masses, located on the gripper rails have to be moved.
- presses are also known in which the distances between the press stands are too small to allow the gripper rails to protrude between these stands. In such presses, the gripper rails must therefore be arranged within the spaces between the press stands and also moved back and forth, so that only a limited space is available for the drive for these movements of the gripper rails.
- presses with gripper rails of this type are already known, in which the movements of the gripper rails run transversely to their longitudinal extent within the distances of the press stands, this requires drives which are arranged outside the press outline and, because of the movements thus running outside the press outline, special protective measures for the operators and beyond require safety clearances.
- Linear drives which are arranged at right angles to the gripper rails from the press outline and are arranged transversely to the feed movement and to the longitudinal extension of the rails are known, which not only require the safety distances mentioned, but also make the accessibility and the possibility of observing the course of the gripping and feed movements more difficult because a user must be at a correspondingly large distance from the gripper rails.
- the object is therefore to create a device of the type mentioned at the outset, in which the drive or drives of the gripper rails, in particular the drives for the gripping movements themselves, do not have to perform any outward movements transversely to the outline of the press in order to move the gripper rail or to be able to adjust the gripper rails in the gripping movement and in opposite directions.
- This task also applies to a device with only one gripper rail, on which appropriate grippers for workpieces are arranged.
- the device defined at the outset is characterized in that the two levers pivotably articulated on the gripper rail act pivotably with their ends or regions facing away from the gripper rail on sliding parts which can be moved towards or away from one another parallel to the direction of extension of the gripper rail and for the back and forth When the gripper rail moves transversely to its longitudinal extent, the distance between these sliding parts can be changed and the gripper rail is positively guided transversely to its direction of longitudinal extension.
- the drive for the transverse movement of the gripper rail thus initially causes a movement parallel to this gripper rail, namely on the sliding parts.
- the levers are pivoted, as a result of which this parallel movement of the sliding parts is converted into a transverse movement of the gripper rail via the levers.
- the gripper rail can, as desired, be adjusted parallel to itself, whereby a positive guidance ensures the correspondingly precise parallel adjustment.
- Movements that take place transversely to the longitudinal extension of the gripper rail for an adjusting drive can thus be avoided, so that the drive and the levers can be arranged within or largely within the outline of the press stand, for example between two such press stands, so that there is not only none over the outline the press stand gives movements transverse to this outline, but the drive can also be accommodated largely within this outline of the press or at least within the usual outline of protective doors on such presses.
- the levers and the drive of the sliding parts can thus be arranged at least partially within the outline of stands of the press, in particular between two press stands which are adjacent to one another in the feed direction. This enables a space-saving arrangement of not only the gripper rails, but also their drive within the press, which also makes it easier for the operating personnel to observe and control.
- the drive for the feed movements of the gripper rail or gripper rails in their longitudinal extension direction is at least partially arranged within the outline of the stand of the press.
- the gripper rails can be moved in their longitudinal direction without the drive required for this having to protrude significantly beyond the outline or outline of the press.
- it can also be located entirely within the outline or layout of the press.
- An effective and space-saving forced guidance for the transverse movement of the respective gripper rail can be achieved in that pivot arms are articulated on the levers between their points of attack on the gripper rail and the respective sliding part are pivotally attached, and that the distance between the sliding part on the one hand and the sliding element or bearing on the other hand can be changed or increased for the transverse adjustment or during the transverse adjustment of the gripper rail.
- the respective lever is thus stabilized with a swivel arm, so that the adjustment of the Sliding parts to change their respective distances leads to a safe and precise parallel adjustment of the gripper rail.
- a further development can provide that the swivel arm crosses the lever at the common articulation point and also acts on the gripper rail via a joint, the articulation points of the lever and the swivel arm pivotally attached to it on the gripper rail with respect to their spacing when adjusting the gripper rail to itself can be changed analogously to the distance between the sliding part and the sliding element.
- the gripper rail is practically gripped by one or two scissors and adjusted transversely to it, whereas in the case in which the swivel arm does not extend to the gripper rail, one can speak of "half-scissors" and swivel arm, the "half scissors" has the advantage that a joint near the gripper rail can be saved.
- the articulation point of the swivel arm facing away from the lever and the gripper rail and the adjoining articulation point of the lever located on the sliding part is adjustable relative to it parallel to the longitudinal extent of the gripper rail.
- an adjustment element can be avoided or at best designed as a stationary part or bearing on which the corresponding swivel arm only has to perform swivel movements.
- the entire kinematics for the transverse adjustment of the gripper rail is correspondingly simple by changing the spacing of the sliding parts for the corresponding pivoting of the levers.
- the two sliding parts of the two levers engaging on a gripper rail can be moved closer to one another for the adjustment of the gripper rail and can be moved away from one another for the opposite gripping movement, and the articulation points of the swivel levers can in particular be stationary.
- the gripper rail or gripper rails can be movable in their direction of advance in the direction of advance by the fact that the articulation points of the levers and the swivel arms facing away from the gripper rail can be adjusted by means of a slide on a guide arranged parallel to the gripper rail and for this Adjustment movement, for example, a spindle motor or working cylinder or a linear drive are provided.
- a carriage is understood to mean a part which engages with a counter-guide on a guide and thereby engages in this guide and / or engages around the guide.
- the entire arrangement of the gripper rail, lever, swivel arm and its articulation points including sliding parts can be adjusted in order to be able to carry out the desired feed movement of the gripper rail and also to reset it.
- the sliding parts - for • transverse adjustment of the gripper rail - may be provided in which attack the respective threaded portions of the spindle is a two oppositely directed threaded regions having spindle and having on the sliding parts in opposite directions threaded spindle nut and the spindle may have a single drive motor.
- a single drive motor is sufficient in spite of the two levers and the sliding parts actuating them when using an opposing spindle, so that this drive can be space-saving and inexpensive.
- the carriages which have the articulation points of the levers and the swivel arms facing away from the gripper rail and form one
- Gripper rails belong can be coupled to one another or, in particular, connected via a connecting rod, so that a single feed drive can be sufficient for each gripper rail, which can adjust these coupled slides together.
- a particularly expedient further development of the invention which is particularly advantageous for taking up larger masses or weights, can consist in the fact that the swivel arm acting on the respective lever can be moved in a plane that extends obliquely to the plane in which the levers can be moved. This results in a tensile or compressive load on the swivel arms, whereby the
- . can be enlarged so that heavier rails and / or heavier workpieces and / or lighter levers and / or swivel arms are made possible.
- the swivel arm (s) can plane of movement of the levers run obliquely upwards or obliquely downwards regardless of whether the movement plane of the levers is arranged horizontally or likewise obliquely upwards or obliquely downwards with respect to a horizontal plane. It is important for the bracing of the scissors or half-scissors drive that the ends of the pivot arms facing away from the levers and the ends of the levers adjacent to these are arranged at different heights and that the pivot arms approach the levers in the direction of the common joint.
- the drive devices for the gripper rails can be mounted on vertical guides or threaded spindles and can be moved up and down, so that objects gripped by the gripper rails can also be raised and / or set down.
- a lifting unit can be provided for each press stand, which makes it possible to carry out an overstroke upwards or downwards with respect to the transport plane, wherein pneumatic mass balancing can be provided.
- the front and rear lifting units in the feed direction can be connected to a base crossbar on which the feed drive for the gripper rails can be mounted.
- FIG. 1 is a front view of a press, which is only partially drawn and outlined, between whose stands a device according to the invention for the gradual advancement of workpieces is arranged, which is also adjustable in height,
- Fig. 2 is a plan view of the arrangement of FIG. 1, with stands of the press or the like processing machine being recognizable in outline with regard to their cross-section, and pivotable levers and pivot arms serving to guide them for the movements of the gripper rails transversely to their longitudinal extension on traverses located between the stands are mounted, two gripper rails movable towards and away from one another being provided,

- a device designated as a whole by 1, is used, in particular, for the gradual advancement of workpieces (not shown in detail) within a press 2, which is only partially illustrated or indicated, in which the workpieces are subjected to an additional machining operation after a feed movement or after a feed step.
- the device 1 Analogous to DE 102 06 773 C1, the device 1 has two parallel gripper rails 4, which are also parallel to the longitudinal center LM and are movable in their longitudinal direction and thus in the direction of advance and can be retracted, on which gripper parts or gripper areas for gripping the gripper rails, not shown but in a known manner Workpieces are provided. 3 to 8 indicate at the same time that a device 1 could also be provided with only one gripper rail 4 if it has corresponding grippers or gripper parts for the workpieces.
- the respective gripper rail 4 can be moved parallel to itself, in the case of two gripper rails 4 they can be moved towards one another and again for releasing, while the already mentioned movements in the longitudinal direction of the gripper rails 4 are provided for the advance.
- the gripper rail 4 can first be seen in a left and then in a right position.
- FIGS. 5 and 6 show an opposite feed movement of the gripper rail 4, which is also displaced away from the longitudinal center LM in relation to FIGS. 3 and 4 and thus has released one or more workpieces.
- FIGS. 4 and 5 or 3 and 6 show that for the back and forth movements of the gripper rails 4 transversely to their longitudinal extension or parallel to themselves, the distance of these sliding parts 6 can be changed, the respective gripper rail 4 also in to be described is positively guided transversely to their longitudinal direction.
- the gripper rail is located closest to the longitudinal center LM of the press, thus assuming its gripping and conveying position.
- the levers 5 and the drive 7 to be described for the sliding parts 6 are located practically completely within the outline of the stand 3 of the press 2 and between two longitudinally adjacent press stands 3 which are adjacent to one another in the feed direction.
- the drive 7 and the levers 5 interacting with it do not require any space outside the layout of the press 2.
- the drive 8 for the feed movements of the gripper rail 4 or gripper rails 4 in their longitudinal extension direction is, according to FIGS. 2 to 8, at least partially arranged within the outline of the stand 3 of the press 2, the slight overhang recognizable in FIG. 2 in any case within the usual outlines of protective doors located on such presses 2 can be accommodated.
- the articulation point 12 and the end of the gripper rail 4 which is remote from it are pivotably attached to displacement elements or fixed bearings 13.
- the distance between the sliding part 6, on the one hand, and the displacement element or bearing 13, on the other hand, can be changed and / or increased for the transverse adjustment or during the transverse adjustment of the gripper rail 4, as the comparison of FIGS. 4 and 5 or 7 and 8 illustrates.
- the swivel arm 11 only runs between its articulation point 12 and the bearing 13, which results in a relatively simple kinematics with the aid of the lever mechanism, consisting of lever 5 and swivel arm 11.
- this arrangement corresponds to "half a pair of scissors" that allows effective cross-adjustment of the gripper rail 4.
- FIGS. 7 and 8 shows that the swivel arm 11 crosses the lever 5 at the common articulation point 12 and also acts on the gripper rail via a joint 14, the articulation points 9 and 14 of the lever 5 and the swivel arm 11 pivotable thereon on the gripper rail 4 with respect to their distance .
- the gripper rail 4 transversely to itself, analogously to the distance. of the sliding part 6 and the displacement element or bearing 13, as can be seen from the comparison of FIGS. 7 and 8.
- the joints 14 of the swivel arms 11 are as close to one another as the sliding parts 6 of the levers 5 this case with the arrangement of lever 5 and swivel arm 11 around “real” scissors, that is to say in the exemplary embodiment according to FIGS. 7 and 8, the gripper rails 4 are adjustable and positively guided by scissor drives parallel and parallel to themselves.
- the articulation point of the swivel arm 11 facing away from the lever and the gripper rail 4 and on the bearing 13, as well as the articulation points 9 of the lever 5 on the gripper rail, are stationary, that is to say only that in the exemplary embodiment according to FIGS. 2 to 6 on the respective sliding part 6 located articulation point 10 of the lever 5 must be adjusted.
- the two sliding parts 6 of the two levers 5 engaging on a gripper rail 4 are therefore movable towards one another and for the gripping movement of two gripper rails 4 from one another or from one another for adjusting the gripper rail 4.
- the articulation points on the bearings 13 of the swivel levers 11 advantageously remain stationary.
- the gripper rails 4 can be moved in their longitudinal direction into the position according to FIG.
- this can be done in that the articulation points 10 of the levers 5 facing away from the gripper rail 4 and the articulation points or bearings 13 of the swivel arms 11 are adjustable by means of slides 15a on a guide 15 arranged parallel to the gripper rail 4 and that this adjustment movement is, for example, a spindle motor 8 with the threaded spindle 8a and the spindle nut 8b which is axially adjustable by the rotation of the threaded spindle 8a and which is connected directly or indirectly to the carriage or the carriages 15a or instead Working cylinders or another linear drive are provided.
- 3 and 4 or 7 and 8 clearly shows how the spindle nut 8b is axially adjusted relative to the spindle 8a by the motor 8 depending on the position of the gripper rail 4 together
- a spindle 16 having two opposite thread areas and spindle nuts 17 having opposite threads on the sliding parts 6 are provided, on which the respective threaded areas of the spindle 16 can be rotated attack, wherein for the spindle 16, a single drive motor 7 is sufficient to adjust both sliding parts 6 towards or away from each other.
- the slides 15a which have the articulation points 10 of the levers facing away from the gripper rail 4 and the bearings 13 with the articulation points for the swivel arms 11, keep their mutual distance when they are displaced, as the comparison of the individual figures shows, and can therefore be with one another be coupled or connected via a connecting rod which can be arranged on the crossbar 19 having its guides 5.
- a feed drive 8 is sufficient for each gripper rail 4 and its slide 14, in the exemplary embodiment with the spindle 8a. 9 to 14 show in different arrangements that the pivot arm 11 acting on the respective lever 5 lies and is movable in a plane which extends obliquely to the plane in which the levers 5 are located and are pivotable.
- FIG. 9 shows an example in which the relatively solid levers 5 are arranged horizontally and can be pivoted in a horizontal plane in order to actuate the gripper rails 4 accordingly, while the pivot arms 11 run obliquely upwards.
- the swivel arms 11 form tension rods, whereas in the exemplary embodiment according to FIG. 10 they are compression rods, but in both cases they are the resilience or the
- the helix angle between lever 5 and swivel arm 11 is an acute angle, the apex of which is arranged in or at the articulation point 12 of swivel arm 11 on lever 5.
- levers 5 are in turn arranged obliquely to a horizontal plane and are movable
- the levers 5 starting from the sliding parts 6 being arranged obliquely upwards and opposite in FIG. 5 in FIG are.
- the swivel arms 11 in turn are arranged obliquely to these levers 5 and their planes of movement.
- the swivel arms 11 run obliquely downwards from their articulation points 12 and are pressure rods, while according to FIG. 12 they extend obliquely upwards from the articulation points 12 with respect to the lever 5 and form tension rods.
- FIG. 13 and 14 are examples of obliquely arranged levers 5, with FIG. 13 representing an example in which the associated swivel arms arranged obliquely with respect to the levers 5 are pull rods in the case of levers extending obliquely upwards, while the reverse arrangement according to FIG .14 shows obliquely to the gripper rails downward lever 5, on which the inclined swivel arms 11 below act as pressure rods.
- the swivel arms 11 thus run obliquely upwards or obliquely downwards with respect to the plane of movement of the levers 5, regardless of whether the plane of movement and the course of the levers 5 are arranged horizontally or likewise obliquely upwards or obliquely downwards with respect to a horizontal plane.
- the swivel arms 11 are given a double function by this inclination relative to the levers 5, in that they effect precise guidance when adjusting the gripper rails 4 parallel to themselves and additionally stiffen the support system for the gripper rail 4 formed by themselves and by the levers 5 ,
- FIGS. 1 and 10 to 14 it can also be seen that the drive devices 7 and 8 with the slide 14 and their guides and the cross member 19 are mounted on vertical supports 21 fastened to the stands 3 and are attached by means of threaded spindles 20 and threaded nuts. and can be moved. In this way, the height of the gripper rails 4 can also be adjusted, that is to say they can carry out lifting and lowering movements.
- the device 1 for gradually moving workpieces within a press 2 or a comparable processing device has at least one or two gripper rails 4 which can be moved back and forth in their longitudinal direction of extension and in the feed direction and which are adjustable transversely to themselves for gripping workpieces.
- the gripper rail 4 has levers 5 which run obliquely to it and can be moved in opposite directions, whose ends facing away from the gripper rail can be moved towards or away from one another, with pivot arms 11 being articulated to guide the resulting transverse movement on the levers 5, which are connected to the levers 5 together form a pair of scissors or half scissors.
- the adjustment movement of the gripper rail 4 can be carried out parallel to itself even in the smallest of spaces and without a drive projecting beyond the longitudinal extent of the gripper rails 4.
