Definitions

  • the invention relates to a production system for the automatic processing of metallic workpieces carried by pallets, in which a pallet storage device is arranged between at least one processing machine and a guideway for the transport of the pallets, from which the processing machine is supplied.
  • the invention is based on this prior art and sets itself the task of designing manufacturing systems so that metal sheets can be automatically fed to the sheet metal working machines, without realizing that significant changes have to be made to them.
  • a pallet store designed as a high-bay rack for pallets loaded with sheet piles is arranged at a distance from the input station of the processing machine and the space is filled by a conveyor that is vertically movable along the pallet store and with a pallet changing device, as well as with a Separating device for automatically inserting individual sheets into the processing machine is provided.
  • High racks for the storage of sheet metal stacks which are carried by pallets are known. It is also known to arrange longitudinally and transversely as well as vertically adjustable conveyors in connection with such high racks.
  • the invention discloses numerous proposals for fulfilling this condition.
  • the inventive separation device has vertically and horizontally movably guided suction heads acting on the sheet metal surface. These should be able to lift the top sheet in the stack and feed it to the processing machine.
  • the conveyor has a sheet-metal support table with sliding elements on the side facing the processing machine
  • the support level in the transfer position of the conveyor is above the feed level of the processing machine and is designed to change its position for the purpose of connection to this feed level. It is advisable to do this if the sheet support table on the conveyor is pivoted about an axis above the feed level and is equipped with a rotary drive. In this way, the possibility is opened to advance the respective top sheet along the sheet support table until, by pivoting this table, a heavy-weight automatic insertion of the sheet metal into the processing machine can take place.
  • the particular problem of the invention is, however, that the individual sheets of a sheet metal stack can be separated from one another.
  • Metal sheets are normally provided with a layer of grease on the surface, which greatly increases the adhesion between the individual sheets.
  • the invention therefore discloses, within the scope of a general inventive concept, the arrangement of magnets on both sides next to the stack near its corners facing the processing machine, in such a way that the positive and negative poles are held at a distance above one another in a magnet holder and face the stack.
  • Such magnets can be designed as permanent magnets or as switchable electromagnets. If permanent magnets are used, they must be adjustable, in particular pivotable, from an inactive to the active position. Switchable electromagnets can remain in their position, provided that the control is an excitation of the magnets only allowed during the separation of the ßleche.
  • the effect of the magnets arranged and designed according to the invention is that when excited due to the magnetic flux, the steel sheets lying on top of one another tend to spread apart.
  • the magnetic excitation of the steel sheets thus releases the adhesive bond between the steel sheets in the area facing the processing machine, with the result that the steel sheets move relative to one another along the conveying direction, in such a way that the top sheet moves the farthest in the rearward direction from the original formed stack shifted.
  • suction heads are articulated to perform this work. It is advisable to arrange suction plates articulated on the suction heads.
  • suction heads acting on the sheet metal surface be provided with a vertically acting vibration drive. It has been found that under this repeated vertical impulse load, the sheets are loosened from one another, ie their adhesion is reduced.
  • the invention provides for the arrangement of a measuring device for sheet thicknesses in the transition region between the conveyor and the processing machine, it being particularly advisable to train this measuring device in the farm of an ultrasound measuring device
  • a measuring device has the property of determining differences in the thickness of sheet metal and even measuring air layers between sheet metal layers.
  • FIG. 1 is a perspective view of a manufacturing system
  • FIG. 2 a side view of the manufacturing system according to FIG. 1.
  • FIG. 1 symbolically shows a processing machine 1, which can be designed, for example, in the form of a punch, scissors, press or the like for sheet metal processing.
  • This processing machine 1 is preceded by a feed plane 2 for the workpieces to be machined.
  • a feed plane 2 for the workpieces to be machined.
  • the output level 3 is provided behind the processing machine 1 in the exemplary embodiment. It can also be arranged on the side of this processing machine 1.
  • a pallet store 4 in the form of a high rack, in the compartments of which 5 pallets 6 with sheet metal stacks 7 arranged thereon are inserted in any way.
  • the space 8 between this pallet storage 4 and the processing machine 1 is occupied by a conveyor 9, which is movable along the lifting direction 19 in height on the pallet storage 4. In this way, the possibility is given that the conveyor 9 can remove a pallet 6 from any compartment 5 of the pallet store 4 or insert it into this compartment.
  • the conveying device 9 has a pallet changing device 10 (which is only shown symbolically because it is previously known for high-bay racks) and a separating device 11, which will be described in detail later.
  • the conveying device 9 should be able to be advanced in the lifting direction 19 by a certain distance in order to receive a pallet 6 from the pallet store 4 or to deliver it to the latter.
  • the pallet changing device 10 is part of the conveyor device 9. It corresponds to the equivalence that such changing devices can also be arranged on the pallet store 4. Since they are known in principle, no constructive representation is required.
  • Pallet storage 4 is a guide 12 for one or several carriages 13, on which hangers 14 for sheet metal stack 7 or (not shown) pallet changing devices or the like hang on lifting arrangements 14, which in turn ensure that sheet metal stack 7 can be moved along the guides 12, 14. It is provided, for example, that empty pallets 6 are moved along the conveying direction 17 with the aid of a driving device 27 to a loading station, where they are loaded with the sheet stacks 7 according to the device 12-15.
  • This driving device 27 can also be equipped with a lifting table in order to bring the pallets 6 into the individual compartments 5.
  • a spreading arrangement 18 in the form of magnets is also shown symbolically in FIG.
  • These magnets 18 have the task of spreading the ßleche of the sheet stack 7 from each other when excited.
  • the individual magnet 18 has positive and negative poles arranged one above the other and at a distance from one another on the side facing the stack 7. It is intended to achieve a magnetic flux between the poles of the magnets 18, which leads to the spreading of the sheets.
  • the magnets are permanent, they must be arranged so that they can move. These can be pivoted, for example, along a horizontal axis which extends parallel to the conveying direction 17 in order to reach an ineffective position. If the sheets from the stack 7 are to be separated, the magnets 18 must, however, be moved into the position according to FIG. 1. The same effect can be brought about by linear movements of the magnets 18, for example in the vertical direction. It is also possible to provide switchable electromagnets and to bring about the effect by switching.
  • the individual suction heads are assigned 20 movements in different directions.
  • the example shows, on the suction head 20, swivel-mounted suction plates 21, which have the task of tilting the uppermost sieve in the stack of metal sheets 7 follow and still create adhesive effect to this ßlech.
  • Dashed lines are provided in Figure 2 on the right and left side of the conveyor 9 stables with different positions of the suction plate 21.
  • a sheet support table 23 which has slide-promoting elements 24 on its upper side.
  • This sheet support table 23 is pivotally mounted about a joint 25, which is located above the intake plane 2 of the processing machine 1. This table 23 can be moved by a swivel drive 26 around the joint 25.
  • the sheets of the sheet stack 7 are separated in the following way:
  • the magnets 18 or a spreading arrangement with a similar effect are excited according to FIG. 1, which has the consequence that the sheets in the area facing the processing machine 1 distance from one another. This results in a relative displacement of the sheets in such a way that the uppermost sheet of the sheet stack 7 protrudes furthest backwards at the rear end.
