Definitions

  • the invention relates to a method and a device for cutting out objects from sheet material.
  • the invention relates to such a method in which, in a first station, a plurality of material webs or a plurality of sections of a material web are stacked one above the other and substantially congruently to form a stack.
  • a laying device is usually used for this purpose.
  • the individual sections of the web of material can be pulled off a supply roll or a supply bale and cut to length, or they are already pre-cut to length and laid one on top of the other.
  • the assembled stack is then transferred from this first station to a subsequent processing station, where objects are cut out of the stack according to a cutting pattern of a fixed geometry, or the stack is divided into small sections.
  • the stacked webs of material with the objects that have been cut out but not yet detached or isolated are now transferred to a further station, where they are removed. Remnants of the material webs are then disposed of.
  • the stacked material web sections have a length of up to 10 meters, so that the individual stations lined up next to each other, i.e. the first station, the processing station and the removal station, require a total length of 30 meters and more, in addition to the space required by the Supply roll required on the inlet side of the first station.
  • the width of the material web sections which can be 2 meters or more, tools are required needed to remove the cut or isolated objects at the removal station from the middle of the web stack, which are one meter or more away from the edge of the web stack and are therefore not directly accessible by a person.
  • Devices that are currently used to cut objects out of a stack of web-shaped material use support tables or grates that transfer the respective stack of material webs from one station to the next station.
  • the empty support tables or grids are then returned to the first station, in order to then build up a new stack of the web-shaped material thereon.
  • the objects that have been cut out can only be removed when the respective supporting table or grating has been completely transferred from the processing station to the removal station. Also, additional space is required to return the empty support tables to the first station unless the support tables are returned to the first station above or below the processing station.
  • the document GB 1 036 732 A describes a device for cutting out pieces of fabric from a stack of layers of fabric stacked on top of one another.
  • these layers of fabric are stacked one on top of the other on a support surface of an upper conveyor belt in the support area.
  • a form knife with dies Below this support surface is a form knife with dies. After the stack of fabric layers has been assembled on the support surface of the upper conveyor belt, they are transferred over a suitable surface to the belt below, by the belt with the stack and the conveyor belt being driven at the same speed.
  • the tape leads up to a press.
  • the form knives are attached to the conveyor belt and thus form the support for the stack of fabric when the belt is advanced in the direction of the press.
  • the stack has been transferred from the belt or the support to the belt or the forming knives, a new stack can be formed on the support area. Consequently, the total length of the plant consists of the length of the upper conveyor belt, the inclined surface, the length of the press and the length of the conveyor belt between the conveyor belt or inclined surface and the entry area of the press.
  • the method according to the invention provides that, in a first processing step, a plurality of material webs are stacked one on top of the other, essentially congruently, to form a stack. If the material webs are pulled off a material coil or material bale, they are preferably cut to the required length directly in the area of the first station.
  • the material webs are usually stacked on top of one another on a support grid to form a stack, on which the stack remains in the processing station. Only after the objects that have been cut out have been removed from the support grate, after the latter has been conveyed out of the processing station, is the support grate returned to the first station in order to pick up webs of material again.
  • the method according to the invention provides that the material webs are stacked in the first station on a support device which is located above a conveyor device with which the stack of material webs is transported into the processing station, which, however, is decoupled from the conveyor device . Only when a material web stack has been assembled on the support device is this material web stack transferred to the conveyor device, so that the material web stack is deposited directly on the conveyor device, which then transports the material web stack to the processing station.
  • the support device After the material web stack has been completely deposited on the conveyor device in the first station, the support device is returned to its basic position above the conveyor device, so that in this basic position it is again ready for a new material web stack made up of individual material web sections is compiled.
  • the conveyor is decoupled from the support device, for the transport of the material web or for the transport of the material web stack from the first station via the processing station to the Removal area a single conveyor can be used.
  • the cutting device can be moved relative to the stack of material webs. This also means that the conveyor with the web stack in the processing station can be stopped or moved continuously or intermittently according to the requirements for the relative cutting speeds, without taking into account the stacking process in the first station or the progress of the stacking process in the first station got to.
  • the conveyor device is also assigned to the first station, in which the individual material web sections are stacked into a stack, this stacking process is independent of a movement of the conveyor device, which is necessary due to the processing of a material web stack in the processing station, since the conveyor device is in the first station below the support device, decoupled from this, is located.
  • the respective area of the material web stack in which the objects have already been cut out can be conveyed out of the processing station by the conveyor device in order to immediately remove the objects that have already been cut out, although they are still within the material web stack.
  • the objects that have been cut out are easily accessible, even if they are very wide webs of material, viewed transversely to the conveyor device.
  • the length of the entire device can be approximately the length of such a support grid or a corresponding conveyor belt, consequently by about a third, shortened.
  • the material webs are stacked on a support belt, which has a length that corresponds approximately to the length of the material web sections that are to be stacked.
  • This support belt is located above the conveyor belt associated with the processing station and the delivery station and is therefore decoupled from this conveyor belt.
  • the conveyor belt is stopped and the conveyor belt or support belt is pulled off below the material web stack, so that the end of the material web stack extends over the support belt pushed out and placed on the conveyor belt below and then transported to the processing station.
  • the material web stack has left the support belt, its movement is stopped in order to build up a new material web stack on it, decoupled from the conveyor belt.
  • the stack is transferred to the conveyor device located below the support device, in that the support device is pulled off from under the stack.
  • the support device can be designed in such a way that it is pulled off from underneath the stack without generating any significant relative movement between the support device and the lower web of material resting on the support device.
  • the support device is then returned to a basic position in order to build up a new stack of material webs, decoupled from the conveyor device. As soon as the material web stack has been deposited from the support device onto the conveyor device located underneath, a new material web stack can be created on the support device without the material web stack lying on the conveyor device underneath moving from the first station to the second station was promoted.
  • the method according to the invention is also characterized in that, at least during the time at which objects are being cut out of the previously formed stack in the processing station, a new stack can be formed on the support device, although the conveyor device that transfers the previous material web stack into the processing station, can be moved further in order to move the material web stack in the processing station relative to a cutting device, for example a laser beam, and to remove the processed part of the material web stack from the processing station for removal of the cut or lead out isolated parts.
  • a cutting device for example a laser beam
  • a support belt is used as the support device in order to build up a stack of material webs thereon.
  • a support belt can be composed of several narrow belts running side by side, which are preferably deflected around common rollers.
  • At least two conveyor devices are used, one conveyor device being assigned to the area below the support device while the other conveyor device is assigned to the area of the processing station.
  • These at least two conveying devices should be positioned relative to one another in such a way that they form a common support and transport plane for the stack of material webs.
  • the third conveyor is assigned to the output zone, which can nevertheless be kept very short, while the other two conveyors are assigned to the area of the support device and the area of the processing device.
  • a conveyor belt is expediently used as the conveying device, with a cutting grid being provided in the cutting area.
  • the conveyor belt of the conveyor device could also be constructed from a number of narrow belts running alongside one another, just as a wire mesh can be used for the conveyor belt or such narrow belts.
  • the device according to the invention for cutting out objects from web-like material comprises a first station in which several webs of material are stacked one on top of the other, essentially congruently, to form a stack on a support belt or another support device.
  • a laying device can be used for this purpose.
  • a conveyor device is present in order to transfer the stack to a processing station following the first station, as has already been explained above.
  • On the side of the processing station opposite the first station there is an output zone for outputting the cut out and/or separated objects or parts of the material web stack.
  • the at least one conveyor device extends from the first station at least to the end of the processing station.
  • the first station has the support device, preferably a support belt, on which, in a basic position of the support device, the material web is placed or the material webs are stacked to form a stack. It is essential that the support device located above the conveyor so that it is decoupled from the conveyor belt and its drive or conveyor movement.
  • the support device is formed by a support belt that is guided around at least two rollers or cylinders. As this support belt is driven, the material web stack is transferred to the conveyor belt at the level below.

  • the upper side of the upper run forms the support surface for the material web(s) or the material web stack.
  • the part of the support belt that is deflected over the roller is pulled off so that the roller moves underneath the material web and thus the upper part of the support belt, the upper run, on the the material web stack rests, consequently the contact surface, gradually pulls off by the upper run being transferred to the lower run.
  • the material web or the material web stack falls onto the conveyor device located underneath, which then transports the material web stack into the processing device. It is particularly advantageous here that there is no friction between the stack of material webs and the support belt, which is drawn off underneath the stack of material webs.
