Definitions

  • the invention relates to a device for removing freshly pressed moldings in the form of slabs of concrete or the like deformable mass from a press and for placing the moldings on a transport device provided with at least one pallet using a table which can be moved along a guide device with respect to the press the inclusion of the slides, which holds at least two blanks or rows of blanks arranged next to one another perpendicularly and / or parallel to the direction of displacement, and a swiveling device which can be rotated about a horizontally extending pivot axis for transferring the blanks from their horizontal transfer position on the sled into an upright position.
  • Set-down position on the pallet in such a way that the moldings lying one behind the other in the direction of transfer can be successively removed.
  • a disadvantage of this known device is the transfer of the molded article (s) from the upper row into the clamping device.
  • the initially not yet hardened molding lying flat on the slide horizontally is therefore exposed to a not inconsiderable force on its narrow sides on a comparatively small area, which often leads to damage or even breakage of the molding. If the molding breaks, the moldings underneath, which are already deposited on the pallet, are exposed to a considerable risk of damage, so that the fracture of one molding affects several. In any case, such an event requires an interruption in the workflow and a removal of the fragments of the molded article and the other molded articles on the pallet damaged as a result.
  • the invention has for its object to develop a device according to the preamble of claim 1 so that damage to the moldings during removal and settling are excluded with sufficient reliability.
  • this object is achieved in a device according to the preamble of claim 1 in that the slide is divided into so many slide parts which extend parallel to the direction of the pivot axis that each slide part carries only one molding or a row of moldings lying parallel to the pivot axis, that the sled parts can be moved separately in chronological succession in at least one section of the transfer line and that the position of the table or tables of at least the sled part or sled parts following the sled part closest to the drop-off point when passing through the transfer line through the composition an arcuate movement and a rectilinear movement is determined.
  • the moldings which come first in the settling direction are deposited - insofar as in the prior art - by pivoting the associated first slide part in the form of a circular arc, while in a second work cycle the moldings of the second slide part are deposited and so on, if more than two slide parts and there are correspondingly more than two moldings or rows of moldings to be removed one after the other.
  • the moldings of the second and possibly further slide parts remain on their tables until they are set down and are not transferred to any further gripping device. This eliminates the risk of breakage and damage when transferring into the side clamp bracket.
  • the moldings remain in the large holder of the tables, the transfer movement into the setting position can be accelerated and decelerated accordingly, which benefits the required working time of the device.
  • all slide parts can be guided over the transfer path in such a way that the position of the tables over this movement distance is determined by a circular and a linear movement.
  • the first slide part can be exempted from this and, as in the prior art, be limited to an arc-shaped movement with the tables remaining in the same position as the circular path.
  • the composition of two movements provided according to the invention serves to transport the moldings over the slide part (s) in front of it in the correct position into the setting position.
  • the arc-shaped movement and the rectilinear movement can be composed in such a way that they only partially or not overlap and in this respect are attached to one another are closed.
  • An example of this is to first turn the tables of the second sled part in a circular arc shape around the swivel axis until they have reached the vertical position above the drop-off points on the pallet, and then to move them straight down to the drop-down position when the first sled part is in the drop-down position Has left the direction of the transfer route and the pallet has moved one parking space width further.
  • the forward movement through the transfer path can take place for both slide parts at the same time, so that they only have to be movable separately for the return direction and can be moved in a controlled manner in chronological succession.
  • the circular movement and the straight-line movement are combined in a temporal overlay.
  • This enables the movement resulting from the superimposition to be carried out in one cycle, which in turn makes it possible to avoid the stacking of moldings during the transfer process.
  • this instruction gives the possibility of deriving the driving force for carrying out the one movement from the drive of the other movement.
  • a force for performing the transfer movement could be applied to the control lever, which is articulated on one end of the device and the other end on the longitudinally displaceable guide part. This force introduced would simultaneously result in the second partial section being pivoted about the common pivot axis.
  • a preferred embodiment is seen in introducing the drive for the transfer movement into the lever which is rotatably mounted about the pivot axis and executes an arc-shaped movement, and from this movement deriving the force for carrying out the linear movement.
  • the pivot axis or - in a preferred form - the pivot axis common to both or all slide parts are arranged perpendicular to this removal device.
  • the swivel axis device is selected parallel to the direction of the displacement distance which the slide parts travel between a transfer point located inside the press and the supporting point, which is the starting point of the transfer movement for the depositing process of the moldings.
  • the pivot axis is perpendicular to the transport movement of the pallet.
  • the device designated overall by 1 has a press 2 which is only indicated in the drawing. Furthermore, a slidably guided slide 4 with tables 5 is provided on longitudinal guides 3 for receiving concrete slab moldings, which are deposited as edged moldings 6 on a pallet 7, which belongs to a transport device. A magazine 8 is provided for reserve pallets.
  • the carriage 4 is formed u divided parallel to the direction of displacement, so that a first carriage part 10 (with a short lever arm) and a second carriage part 11 each with a pair of receiving tables 5 is formed.
  • Each slide part has two guides designed as guide rods 3.
  • Both slide parts 10, 11 are positively coupled for displacement in the displacement direction 9, for which purpose the first slide part 10 has a recess 12 and the second slide part 11 has a nose 13 engaging therein.
  • a crank mechanism, generally designated 14 is provided, which likewise has a nose 15, which engages in a recess 16 in the second slide part 11 which is adapted to this.
  • Both form-fitting nose-recess connections are designed so that when pivoting about a pivot axis 17 arranged parallel to the direction of displacement 9, they disengage (for both slide parts 10, 11) and thus cancel the positive connection.
  • the first slide part 10 is in this case driven by a swivel drive, formed by the motor 18 and a crank mechanism 19, via the push rod 20 and swivels here about the swivel axis 17 of a two-armed lever 21, the clamping devices resting on the tables 5 being held by means not shown Shaped pieces in a swiveling movement, as indicated schematically by the double arrow 22, are transferred and placed on edge on the pallet 7. Then the first slide part 10 is pivoted back by the swivel drive and the pallet 7 is transported further by the thickness of a molding 6.
  • the second carriage part 11 is shown in more detail in FIG. 2. It has a two-armed lever 23 which can be pivoted about the axis 17 and at one end 24 of which a crank mechanism 26 engages via a push rod 25.
  • the other end 27 of the two-armed lever 23 has a longitudinal guide 28, along which a guide part 29 is guided so as to be displaceable in a straight line.
  • the two guide rods 3 of the second slide part 11 are attached to this guide part 29.
  • There is also a control lever 31 which is mounted with its one end 30 outside the axis 17 and is fixed to the device, the other end 32 of which is articulated on the sliding part 29.
  • This control lever ensures that the (shown) carrying position for the second slide part 11 or its tables 5 or the moldings 6 placed thereon is fixed at the beginning of the transfer path and that the (shown in broken lines) lowering position at the end of the transfer movement of the double-armed lever 23 is safely reached so that the molding can be placed on the pallet on its edge.
  • the sliding part 29 is pivoted on the one hand as a result of the pivoting movement of the two-armed lever 23 about the axis of rotation 17 in an arc-shaped path (arrow 22) and at the same time offset by the control lever 31 along the sliding guide 28 in a straight line, so that the moldings of the second slide part 11 over the Tables of the first carriage part 10 are moved along a transfer path obtained from the superimposition of the pivoting movement and the linear movement.
  • the slide parts 10 and 11 including the respectively associated sliding guides 3 are pivoted to carry out the transfer movement or, in the case of the slide part 11, pivoted and offset in a straight line.
  • the sliding drive 14 engages with its nose 15 in the recess 16 provided on the slide part 11 and that the nose 13 formed on the slide part 11 engages in the recess 12 provided on the first slide part 10.
  • both slide parts are connected to the displacement drive and can be displaced along their guides 3 between the position shown in FIG. 3a for taking over the moldings from the press frame and the carrying position, from which the slide parts are transferred into the depositing position.
  • the coupling lever 34 engages in the groove 33 and thus blocks the sled part by moving back and forth through the transfer line against displacement in the direction of arrow 9 until the sled part comes back into the carrying position.
  • the first slide part 10 must additionally be secured against displacement when the second slide part 11 is in the transfer path, since the coupling with the displacement drive 14 is then also interrupted for the first slide part. This is done with the aid of a two-armed connecting lever 35 which lowers the coupling lever 34 into engagement with the associated groove 33 of the first slide part 10 when and as long as the second slide part 11 is in the transfer path, as shown in FIG. 3b.
  • a two-armed connecting lever 35 which lowers the coupling lever 34 into engagement with the associated groove 33 of the first slide part 10 when and as long as the second slide part 11 is in the transfer path, as shown in FIG. 3b.
