Definitions

  • the invention relates to a device for punching a conveyed surface element, in particular for punching a strip with containers formed in this strip, in particular by deep drawing, comprising at least one upper punching tool and comprising at least one lower punching tool, which can be moved relative to one another to carry out the punching.
  • Containers are regularly arranged in a bowl shape within conveyed surface elements, in particular within conveyed belts made of foil.
  • the trays are arranged regularly by deep-drawing the film. Treatment lines are known for this, in which a strip is transported further after the container has been deep-drawn.
  • the containers are arranged in certain areas of the belt, they can subsequently be filled and then closed, for example by sealing on a film.
  • the containers formed into the belt must then be separated by separating them from each other in the longitudinal direction of the belt and in the transverse direction to the belt conveying direction. This separation is carried out using generic devices.
  • a band into which containers are formed by deep drawing has a thickness of, for example, 1 millimeter. It is usually made of plastic. Punching such a material requires high forces.
  • a servo drive which includes a servo motor with a belt drive and spindle. With With such a servo drive, a lower punching tool is raised in order to guide it against the upper punching tool in order to carry out the punching.
  • the invention is therefore based on the object of providing a device for punching of the type mentioned at the outset, with which punching with high forces is possible without the occurrence of bends in the tools involved.
  • At least one movement device for a punching tool has at least one crankshaft lying approximately transversely to the conveying direction of the surface element and transversely to the direction of movement of the punching tool, to which connecting rod elements are articulated, the ends of which facing away from the crankshaft are articulated to the punching tool.
  • a crankshaft for driving at least one tool for punching the surface element.
  • a crankshaft can initially be made solid so that it can absorb high forces. It can be supported several times to prevent it from bending.
  • the crankshaft is arranged transversely to the conveying direction of the surface element and also transversely to the direction of movement of the tool. It follows that the crankshaft can extend, for example, over the entire width of the conveyed belt and can therefore support a punching tool that approaches the belt over the entire width of the belt. This counteracts any deflection of the tool due to the high forces.
  • connecting rod elements This support of the tool is provided by the connecting rod elements provided.
  • Several connecting rod elements are provided; they are distributed over the longitudinal extent of the crankshaft.
  • the connecting rod elements are articulated on the one hand on the crankshaft and on the other hand on the tool, so that forces emanating from the crankshaft can be transmitted to the tool during rotation of the crankshaft.
  • the punching tool is guided displaceably in a stand structure.
  • the punching tool is held in sliding guides, which are components of the frame, so that the punching tool is guided in the frame, for example, so that it can move upwards and downwards.
  • the punching lower tool is accommodated on a guide in the stand structure and that the connecting rod elements are articulated on this guide.
  • a guide is provided for the punching lower tool, which is displaceably accommodated in the frame.
  • the punching lower tool is arranged on this guide; for example, it rests on this guide.
  • the connecting rod elements are articulated on the guide and are therefore articulated in the area of the lower punching tool. Forces are transferred from the connecting rod elements to the guide and thus also to the punching lower tool held on the guide.
  • crankshaft has crank sections; the connecting rod elements are preferably articulated on these crank sections.
  • a rotation of the crankshaft can be converted into a translational movement of the tool due to the crank design and the articulation of the connecting rods, since the rotational movement of the crank is transmitted to the tool via the connecting rods and this is moved translationally in its displaceable guide in the frame.
  • adjacent crank sections have an offset from one another on the circumference of the crankshaft.
  • Adjacent crank sections can be arranged in a line on the circumference of the crankshaft. If, as suggested by this development, adjacent crank sections on the circumference of the crankshaft are offset from one another, then a defined force input via the connecting rod elements into the tool, for example the lower tool, is possible. It can thus be provided that a force is first introduced into one end of the tool and then forces are only introduced into other sections along the longitudinal extent of the tool. This allows force peaks to be placed on certain areas of the tool, resulting in a force rolling effect and thus an active cutting effect.
  • the punching tool can have a top bar in the punching area.
  • This top bar is preferably designed in one piece and covers the entire punching area.
  • the top bar is preferably hardened and flexible so that no offset occurs over the punching area.
  • At least one drive is assigned to the crankshaft, for example an electric motor.
  • Both punching tools are preferably held in the frame so that they can be adjusted in height. If the crankshaft is assigned to the lower punching tool, then the upper punching tool can also be held in the frame in a height-adjustable manner.
  • the device in Figure 1 has a machine frame 1 that supports several work stations. 2 denotes a deep-drawing station.
  • containers 5 are formed into a surface element 4 unrolled from a roll 3, in particular a film strip.
  • the surface element 4 is transported further along arrow 6, for example filled with objects and guided to a sealing station 6.
  • the containers 5 are closed with a sealing film 7 in this sealing station 26.
  • the containers 5 are then transported to a cutting station 8.
  • the containers 5 are cut with a rotating knife 9 parallel to the conveying direction of the surface element 4.
  • Cutting transversely to the conveying direction of the surface element 4 is carried out using a punching device 10.
  • Figure 2 shows a component of the punching device 10, namely a component of the upper punching tool 11. This extends over the entire width of the surface element 4, which is held in chains 12 on its longitudinal edges for its transport.
  • Containers 5 shown are to be separated from each other transversely to the conveying direction (arrow 6) of the surface element 4 using the punching device 10. Punching takes place along a line 13.
  • Figures 3 to 5 show the punching device 10 during a punching process.
  • a surface element 4 is punched, which is fed to the punching device 10 along the conveying direction marked by arrow 6.
  • This in Figures 2 to 5 Punching upper tool 11 shown is accommodated in a frame structure 14.
  • a punching lower tool 15 is also accommodated in the stand structure 14.
  • Figure 3 shows the bottom one, Figure 4 a medium and Figure 5 the top position of the lower punching tool 15.
  • a lifting drive is provided for this lower punching tool 15, which includes a crankshaft 16.
  • the crankshaft 16 is aligned transversely to the conveying direction (arrow 6) of the surface element 4.
  • the surface element 4 is passed between the lower punching tool 15 and the upper punching tool 11.
  • the crankshaft 16 has crank sections 17 to which connecting rod elements 18 are articulated.
  • Guides 19 are provided for the lower punching tool 15 and are held displaceably on the stand frame 14. Both guides 19 are connected to one another with a profile element 27.
  • the connecting rod elements 18 are articulated on the profile element 27, which is in Figures 3 to 5 also carries the punching lower tool 15.
  • FIG. 6 and 7 A different exemplary embodiment is in Figures 6 and 7 shown.
  • a middle crank section 17 is arranged offset from the other two crank sections 17 on the circumference of the crankshaft. This ensures that the middle connecting rod element 18 has a lead or on the outer sides compared to the other two connecting rod elements 18 has a wake.
  • the middle connecting rod element 18 can be guided over a dead center, as in Figure 6 shown.
  • crankshaft 16 has been rotated by the drive 20, approximately through 90° Figure 4 corresponding starting position.
  • the movement of the crankshaft 16 and the crank sections 17 has been converted into a movement of the connecting rods 18, with the result that the guides 19 with the profile element 27 have been moved on the stand frame 14 and the lower punching tool 15 is thereby guided in the direction of the upper punching tool 11.
  • the profile element 27 is not formed in one piece. It has a middle section 27 ⁇ which is in Figure 6 with the connecting rod element 18 was lifted a little way out of the longitudinal extent of the profile element 27. This raised position of the profile element 27 'is transferred to the lower tool 15.
  • the lower tool 15 is connected via pins 28 to a console 29 attached to the profile element 27.
  • the console 29 is also divided into sections Figure 6 middle section can be raised with the profile element section 27.
  • FIG 7 shows that the console 29 is placed closely against the lower tool 15.
  • Figure 7 shows the punching position, the connecting rod elements 18 have been raised accordingly with the crankshaft 16.
  • the console 29 also carries a stop plate 30 for the interchangeable positioning of the lower tool 15.
  • the lower punching tool also has a hardened top bar 21 on its top side.
  • This top bar 21 is made in one piece and continuous, but is also flexible.
  • the top bar 21 is applied to the top punching tool 11. By bending it can accommodate that the middle connecting rod element 18 is slightly higher than the outer connecting rod elements 18. In this way, the cutting process begins in the middle of the extension of the lower punching tool 15 and is then guided outwards. If the middle connecting rod element 18 is designed to trail the other two crank sections due to an offset of the crank section 17, then the middle connecting rod element 18 protrudes less far upwards than the outer connecting rod elements 18. In this case, the outer regions of the surface element 4 would be cut first become.
