Definitions

  • the invention relates to a sheet punching and embossing machine according to the preamble of claim 1.
  • a device in which a rotating cutting cylinder is equipped with spaced knives, wherein between the spaced blades a suction and blowing device is set up.
  • a suction and blowing device After separating the waste strip by means of the knife arranged on the cylinder jacket of the waste strip is held by means of negative pressure on the roll shell and can thus be removed.
  • the actual ejection of the waste strip takes place in this case on the one hand, the suction is replaced by a blowing and on the other hand, a suction hood is arranged above the cylinder jacket, so that the waste strip is lifted from the cylinder jacket by the blowing air and on the other hand is attracted by the suction of the suction hood.
  • a generic Bogenstanz- and embossing machine is described, are attached to the circulating chains gripper carriage, which draw by means of grippers arches through a sheet punching and embossing machine.
  • the sheet punching and embossing machine consists of a punching device, a breakout device and a storage device.
  • a gripper edge separated from the sheet is ejected.
  • the ejection takes place here in that the grippers of the gripper carriage are opened, so that the gripper edge falls out.
  • brushes or scraper fingers between the grippers in the machine frame which assist in ejecting the gripper edge.
  • a gripper edge is usually between two centimeters and five centimeters.
  • the gripper edge but also consist of the fully circumferential arc from which the benefit was punched out. This gripper edge in the form of a several centimeters thick edge in the size of the complete sheet must also be stored in the storage station.
  • the gripper opener curve in the ejection station must be adapted to the gripper edge in order to be able to discharge the gripper edge as waste from the machine. For this the machine has to be rebuilt.
  • a gripper opener curve is in a first position and in a gripper edge in the size of a sheet, another gripper opener curve is screwed in another position.
  • the ejection point must be continuously adjusted. This results in particular in a gripper edge in the size of a sheet that on the one hand Umrüst society arise and on the other hand, the machine speed must be reduced to eject the gripper edge in size of a sheet from the machine.
  • the object of the invention is to improve a sheet punching and embossing machine to the effect that can be dispensed with an elaborate retooling of the machine and at the same time with maximum machine power reliable ejection of the different gripper edges is guaranteed.
  • the solution should be cost-effective and feasible with the simplest design means.
  • the object is achieved in that the ejector is acted upon by a blower, so that a directed air flow acts on the gripper edge.
  • the inventive design of a sheet punching and embossing machine the possibility is now created to ensure a safe ejection of the gripper edge without a conversion of Greiferöffnerkurve. In this case, a cost-effective means is used by the use of commercially available speed-controlled fan to realize the ejection of the gripper edge.
  • a plurality of fans are mounted side by side over the entire width of the ejector, so that a fan bar is formed. This ensures that also different sized gripper edges are ejected safely over the entire width of the ejector.
  • a conveyor belt is provided in the ejector below the movement path of the gripper carriage.
  • the fan is mounted within the circular path of the gripper carriage in the machine frame. This ensures that the air flow in the direction of the conveyor belt can be particularly well aligned.
  • the fan outside the circular path of the gripper carriage is mounted as a suction fan in the machine frame. As a result, the gripper edge is reliably sucked out of the gripper carriage.
  • blower as a blowing and / or sucking blower causes a defined ejection of the gripper edge, since in particular the air when ejecting a long gripper edge by the blower, suction and / or blowing are converted into a directed air flow. As a result, a safe placement of the gripper edge is made possible on a running below the path of the gripper carriage waste belt.
  • FIG. 1 the basic structure of a sheet punching and embossing machine 1 for punching, breaking, embossing and storing sheets of paper, cardboard and the like is shown.
  • the punching and embossing machine 1 consists of a punching device 2, a breakout device 3, a storage device 4 and an ejector 24, which are supported and enclosed by a common machine housing 5.
  • the arcs 6 are gripped by gripper bars 8 fastened on circulating chains 7 at their front edge, the actual gripper edge, and pulled intermittently through the various stations 2, 3, 4 and 24 of the punching and embossing machine 1.
  • the punching station 2 consists of a lower table 9 and an upper table 10.
  • the lower table 9 is fixedly mounted in the machine frame and provided with a counter plate to the punching knife.
  • the upper table 10 is in this case mounted vertically movable up and down.
  • the gripper bar 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent Ausbrechstation 3, which is equipped with breakout tools.
  • the breaking station 3 the unwanted pieces of waste are pushed out of the sheet 6 downwards with the aid of the stripping tools, whereby the waste pieces 11 fall into a container-like carriage 12 inserted below the station.
  • the sheet From the stripping station 3, the sheet enters the storage station 4, where the sheet is either simply stored, or at the same time there is a separation of the individual benefits.
  • the storage station 4 may also include a pallet 13, on which the individual sheets are stacked in the form of a stack 14, so that after reaching a certain stack height, the pallets with the piled sheets from the field of punching and embossing machine 1 can be moved out.
  • the chains 7 carry a plurality of gripper carriages 8, so that a plurality of sheets 6 can be processed simultaneously in the various stations 2, 3, 4 and 24.
  • the gripper edge In the storage device 4, the gripper edge, not shown, separated from the sheet 6. In the ejector 24, the separated gripper edge 15 is ejected and transported away by a conveyor belt 17. Ejecting is usually done by opening the gripper 8 or by a combined opening of the gripper 8 and an arranged next to the grippers 8 brushes 21 which eject the gripper edge 15 in the case of the gripper carriage, when the gripper edge 15 despite open gripper 8 in the gripper carriage 8 remains.
  • FIG. 2 shows a side view of a sheet punching and embossing machine equipped according to the invention in the area of the ejection station 24 in which the gripper edge 15 is ejected. It is hereby pointed out once again that the gripper edge can correspond in its dimensions to those of the entire sheet.
  • FIG. 2 shows a conveyor belt 17, which is fastened below a circular track 18 of the gripper carriage 19 in the machine frame 20. The part of the sheet punching and embossing machine forming the circular path 18 for the gripper carriage 19 forms part of the machine frame 20.
  • a stripping brush 21 is mounted in the machine frame 20.
  • a fan 22 is mounted in the machine frame 20.
  • a baffle 23 is screwed below the stripper brush 21.
  • a directed ejection of the gripping edge 15 is ensured by the guide plate 23.
  • the one or more blowers 22 are, in an advantageous embodiment of the invention, one behind the other over the entire width of the machine evenly, but distributed at least at regular intervals to each other, fixed in the machine frame 20.
  • the blowers are speed-controlled, the speed being regulated as a function of the gripper edge and the grammage.
  • the machine speed is included in the control.
  • the air flow and thus the force introduced to the waste steplessly regulated as a function of machine speed.
  • the fan bar can be installed in a sheet metal of the ejection station, which is also referred to as a shelf.
  • the gripper edge 15 is conveyed into the tray 24 shown, in which the gripper 25 of the gripper carriage 19 opens and thus releases the gripper edge 15.
  • the directed air flow which is indicated here by the arrows 26
  • the fan blade 22 By installing the fan blade 22, a constant force in the direction of the waste belt 17 is generated. This causes in an advantageous manner that even long gripper edges can be easily stored on the conveyor belt 17 and transported out of the sheet punching and embossing machine out.
  • the conveyor belt 17 conveys the ejected gripper edges 15 in the direction of the arrow F from the machine.
  • Another advantage resulting from a blowing fan 22 or fan blade 22 is that, with a small clearance to the waste, the waste stream can be better controlled.
  • blowing fan 27 in addition to a blowing fan 22, as shown in FIG.
  • the gripper edge 15 is then not pressed out of the gripper carriage 19 by means of the blower 22, but pulled out of the grippers 25 of the gripper carriage 19 by means of the directed air flow 28 of the blower 27.
  • This offers an advantage if, for example, existing machines are retrofitted or retrofitted with a fan bar 27. Since here the fan blade 27 is mounted behind the circular path 18 of the gripper carriage 19 and the fan bar 27 is easy to install.
