Definitions

  • the invention relates to a loading and unloading device for machine tables constructed from parallel, parallel webs of machines that cut workpieces from sheets and sheets.
  • the machine table consists of a grid of vertically standing narrow webs in machines that cut with a laser or water jet.
  • the webs can carry tips on which the metal sheets are placed.
  • the teeth of a comb are pushed between the webs when the cut parts are to be removed from the machine table.
  • the suction frame and the comb hang side by side on a rail. In this way, in addition to the cut parts, a sheet of metal can be transported at the same time.
  • To insert the teeth of the comb there must be enough space between the webs and for the teeth the webs must be high enough to ensure that the cut parts are held securely. It is also problematic to place the cut parts on a pallet or a trolley, since here too the tines have to be lowered between the bars and exact positioning is required.
  • the aim and object of the invention is to find a loading and unloading device for machine tables with upright webs that gently picks up cut parts and stacks them on the smooth surfaces.
  • Fig. 1 is a schematic side view of the loading and unloading device
  • Fig. 2 is a top view of the loading and unloading device
  • FIG 3 shows the schematic side view of a loading and unloading device paired with a frame carrying a suction device.
  • the loading and unloading device consists of a lifting stand 1 on which a support arm 2 is fastened. 1 and 2, the support arm 2 carries a slidable table top 3, around which narrow conveyor belts 4 are stretched parallel to one another.
  • the table top 3 carries tines 5 which are bent downwards on one side.
  • a machine table 6 is arranged next to the side of the table top 3 which carries the tines 5.
  • On the opposite side of the table top 3 there is a carriage 9 running on rails 8, on which the finished parts are placed.
  • a carriage 10 is coupled to the carriage 9, on which a sheet metal stack is located.
  • the tips of the tines 5 carry rollers 11, over which the conveyor belts 4 run.
  • the conveyor belts 4 run over rollers 12 or over a continuous roller.
  • the support arm 2 there is a drive for moving the table top 3, a lock and a drive for the conveyor belts 4.
  • the sheet is lifted from the carriage 10 with a suction frame, not shown, the table top 3 is pushed underneath and the sheet is placed on the conveyor belts 4. It is also sufficient if the sheet metal on the table top side is tipped with a peeling device and the table top 3 is inserted into the released gap.
  • the conveyor belts 4 then run counter to the direction of insertion and the sheet is taken up by the table top 3.
  • rollers 3 can be attached between the conveyor belts 4 at the edge of the table top.
  • the loaded table top 3 is pushed over the machine table 6 and then pulled under the sheet.
  • the conveyor belts 4 are held so that they run under the sheet and the sheet is gently laid down.
  • the machine table 6 is used to move finished parts.
  • the tines 5 are pushed between the webs 7.
  • the held conveyor belts 4 roll so that they take up the finished parts, since there is no pushing movement between the conveyor belts 4 and the finished parts.
  • the entire table top 3 is pushed over the shelf 9 and pulled out under the finished parts.
  • the conveyor belts 4 now roll on and place the finished parts gently on the shelf 9.
  • the support arm 2 attached to the lifting stand 1 carries a frame 13 to which suction devices 14 are attached.
  • the frame 13 is fastened to the support arm 2 with a lifting guide 15 and can be raised and lowered.
  • the support arm carries 2 rakes 16, which can be moved apart laterally on transverse arms 17.
  • Conveyor belts 4 are tensioned over the prongs 5 of the rakes 16 and are connected to one another in each rake 16 with an existing scraper 18.
  • the rakes 16 are moved apart to accommodate finished parts.
  • the tines 5 of the rakes 16 reach between the webs 7 on the side edges of the machine table 6.
  • the rakes 16 are moved together and the tines 5 are pushed under the finished parts.
  • the conveyor belts 4 roll in such a way that there is no relative movement between the conveyor belts 4 and the finished parts.
  • the retracted rakes 16 are moved apart above the shelf 9 and the finished parts are deposited gently.
  • the frame 13 is raised with the lifting guide 15 via the rakes 16.
  • the frame 13 is lowered, as shown in FIG. 3, between the rakes 16 which have moved apart, and then the Rake 16 moved together again to keep the outer interference contour of the loading system constant.

Abstract

L'invention concerne un appareil pour le chargement et le déchargement des tables (6) de machines à découper des panneaux et des feuilles, comprenant un cadre (13), qui porte une ventouse (14), et un râteau (16). Les dents (5) du râteau (16) sont poussés entre des barres (7), placées sur chant, vertical de la table (6) de la machine afin de recevoir les pièces découpées. Des bandes de transport (4) sont étendues sur les dents (5) du râteau, inclinées vers le bas vers la table (6) de la machine. Les dents (5) peuvent également être montées au bord d'un plateau de table (3). Les bandes de transport (4) sont dans ce cas étirées sur les dents (5) et se déplacent en parallèle les unes à côté des autres, alors que le plateau (3) de la table se déplace latéralement sur la table (6) de la machine et sur une zone de dépôt (9).
