Definitions

  • the present invention relates to a device for the automatic layering of laminated iron cores for transformers and choke coils, with storage magazines for sheet metal blanks, with at least one horizontally displaceable stacking magazine, with a transport carriage which can be moved horizontally above the magazines and to which lifters which can be switched on and off are fitted with drives for moving the transport trolley and for lifting and lowering the lifters, as well as with end contacts for safe sequence control of the shifting process.
  • the known layer devices have magazines for recording the sheet metal blanks to be layered and magazines to hold the assembled core packages.
  • a known device has, for example, a magazine for receiving the E-shaped and the I-shaped sheet metal blanks.
  • the bottom sheet in each case is removed from these magazines and nested with the aid of sliders in the coil former lying on the supply magazine.
  • a device for layering iron cores for transformers and choke coils from single sheets in which sheet lifting units containing gripping elements are attached in the region of the ends of the arms of a centrally mounted turntable or rotating star, with which stacked stacks of the core form are put together in one or more layers Sheets can be lifted off and, after rotating the turnstile, placed on the shift table located at another location on the turntable.
  • the gripper elements of the sheet metal lifting units can be embodied by suction devices or by E1 ktromagnets.
  • the suction cups or electromagnets are arranged to be elastically displaceable in the vertical direction.
  • the gripper elements are arranged at different heights so that the sheet to be lifted is first lifted in a defined area in an end region and the lifting process thus initiated continues uniformly over the entire length of the sheet. In this way, the adhesive and frictional forces acting between the sheets lying on top of each other can be overcome and a safe lifting of the top sheet layer can be ensured. In addition, spreading magnets can be attached in the area of the end faces of the sheet metal stack, which cause the upper sheet metal layers to fan out.
  • the top sheet, gripped by the gripper elements of the slewing ring is after a Rotation of the slewing ring on a shift table, where the sheets are fixed with the help of stud bolts during the shift process.
  • a method for layering laminated iron cores for transformers and choke coils of higher power in which one of the stacked sheets of one is located in one working process by means of a gripper plate on which electromagnets or suction nozzles that are arranged to be elastically displaceable in the vertical direction can be switched on and off the supply table is removed and a sheet removed from another supply table in the previous operation is always placed in the same place on the shift table.
  • the gripper plate can be moved horizontally and vertically.
  • the known device has end contacts which can be arranged both on the gripper plate and on the supply and shift tables.
  • the layer table is designed as a roller conveyor for further transport of the finished iron cores.
  • the storage tables are designed as perforated plates.
  • adjustable stop strips corresponding to the core profile are arranged on the supply tables, which are fastened by means of bolts and can be removed from the finished stacked sheets after rotation about the bolts.
  • the shift table can be moved in the vertical direction by means of a further electric motor. and thus enables the surfaces of all stacks to always be in alignment during the entire layering process.
  • the core stack is then rolled away on the roller conveyor and a new stacking process begins.
  • the present invention is therefore based on the object of improving a device for the automatic layering of laminated iron cores of the type mentioned in such a way that a simultaneous layering of a plurality of core stacks from the sheet metal blanks contained in several magazines is possible, that an uninterrupted layering is possible, and that the storage magazines can be filled with any amount of sheets at any time.
  • the number of storage magazines corresponds to the number of sheet metal blanks to be layered, that the storage magazines are arranged one behind the other in at least one row, that the stacking magazines are arranged one behind the other on an endless conveyor belt, and that a cyclically operating drive for the conveyor belt is present.
  • the storage magazines are preferably arranged in two rows one behind the other, the stacking magazines run between the storage magazines, the number of stacking magazines corresponds at least to the number of pairs of storage magazines, the lifters which can be switched on and off are fastened to both ends of the transport carriage and are the ones of each row of storage magazines assigned rows of jacks can be raised and lowered independently of each other.
  • the overall length of the automatic stacking device can be reduced by half.
  • the layering process is further accelerated in that sheets are taken from the storage magazines each time the trolley is moved, and sheets are deposited in the stacking magazines.
  • the lifters are preferably designed as suction nozzles or as electromagnets.
  • fixed and movable stops are provided on each storage magazine in order to place the magazines on sheet metal blanks of different sizes to be able to adjust.
  • the movable stops of all the storage magazines in one row are preferably adjustable jointly, as a result of which the adjustment work can be further shortened.
  • the suction nozzles are advantageously individually adjustable in position. In this way, sheet metal blanks of any shape can be stored in each storage magazine, as is technically necessary for the stacking process, and at the same time a secure engagement and lifting of the uppermost sheet layer is possible.
  • the suction nozzles are preferably freely movable in the vertical direction. When the suction nozzle holder is lifted, they are pulled from their weight into the lowest position, so that the sheet to be put down has the same height above the stacking magazine. Springs as in the prior art are not required.
  • the stacking magazines are preferably fastened on a chain conveyor and run in an endless loop through the layer device.
  • each stacking magazine is inclined on its conveyor belt in two planes against the horizontal.
  • a fixed angle stop is attached to each stacking magazine so that its tip lies at the deepest corner of the magazine. In this way it is achieved that the sheets that fall freely when put down each slide with a corner into the stop angle, so that all the sheets stacked one above the other have the desired spatial position with respect to one another and one above the other.
  • each supply magazine is assigned an occupancy monitor which prevents the machine from continuing to run even if the operating personnel have forgotten to add sheet metal blanks
  • Vacuum monitors are preferably assigned to the suction nozzles. These vacuum monitors respond immediately if one of the suction nozzles does not catch any sheet or if the sheet falls down again. The missing sheet can then be added manually by the operating personnel.
  • an occupancy monitor can also be assigned to the removal station of the stack magazines.
  • the occupancy monitor With the help of the occupancy monitor, malfunctions of the machine, which can occur due to a stagnation during the removal of the finished core stack, can be safely avoided.
  • the layering process is interrupted until the storage magazine at the removal station is emptied.
  • Each row of suction nozzles can preferably be raised and lowered independently by means of hydraulic cylinders, in particular compressed air cylinders. This measure results in a reduction in the moving masses, which means that the layering process can be accelerated.
  • the transport carriage can advantageously be moved via an eccentric drive.
  • the eccentric drive is driven by an electric motor via a reduction gear.
  • the trolley can also be moved using a compressed air cylinder, a hydraulic cylinder or an electric linear motor.
  • spreading magnets are assigned to each storage magazine. These spreading magnets cause the sheet metal blanks lying in the storage magazines to repel each other at their front edge, which makes it easier to remove the top sheet from the sheet pile.
  • Fig. 1 shows a plan view of an automatically operating stratification device with two rows of storage magazines, between which the sta p elma g azine run.
  • Fig. 2 shows a front view of the device.
  • a frame made up of four vertical beams 1.1, longitudinal beams 1.2, upper cross beams 1.3 and two lower cross beams 1.4. On the lower cross beams 1.4 further beams 2 are fastened in the longitudinal direction, each carrying a row of storage mafatins 3, 4 on their upper side.
  • the stacking magazines 5 arranged on an endless conveyor belt 6 run between the two rows of storage magazines 3, 4.
  • the stack magazines 5 are fed in cycles with the aid of a drive motor 7.
  • the suction nozzles 9, 10 are so created relative to the transport carriage 8 that in one end position of the transport carriage 8 the suction nozzles 9 are above the storage magazines 3, the suction nozzles 10 are above the stacking magazines 5, while in the other end position of the transport carriage the suction nozzles 10 are above the storage magazines 4, the suction nozzles 9 are above the stacking magazines 5.
  • flexible hoses are arranged, which lead to a (also not shown) vacuum manifold, which establishes the connection to a vacuum pump.
  • the stacking magazines 5 fastened on the conveyor belt 6 are inclined in two planes, so that the sheets released by the suction nozzles always fall into the deepest corner against a fixed angular stop 17.
  • the storage magazines 3 each have a fixed angular stop 18 and a movable angular stop 19.
  • the movable stops 19 of each row of storage magazines 3 and 4 can be adjusted together by means of a handwheel 20 and a threaded rod 21 in order to adapt to differently sized magnetic cores to enable.
  • the suction nozzles 9 are lowered onto the sheets 11 located in the storage magazines by means of the left hydraulic cylinders 16. Since the suction nozzles 9 are freely movable in their guides 22 are different lifting of the sheet stack 11 can be compensated. Then the suction nozzles 9 are raised to the position shown and the trolley 8 is pushed into its right end position. The suction nozzles 9 are now located above the stacking magazines 5 in the position that the suction nozzles 10 had previously occupied, while the suction nozzles 10 are now in the indicated position 10 'above the storage magazines 4.
  • the vacuum of the suction nozzles 9 now in the middle is switched off, so that the sheets fall freely into the stacking magazines 5 against the fixed stop angle 17.
  • the storage magazines 4 move forward step by step, the feed being able to take place after each placement of a row of sheets or after every second placement of a row of sheets.
  • the core stacks are cyclically completed continuously through the coating zone of performing the invention during the passage and can at one outside of the actual Removal station 23 lying layer zone are removed without the layering process itself being disturbed.
