Definitions
- the present invention relates to a device for cutting sheets of paper, cardboard or similar materials, the so-called s sheets being transformed into multiple poses and the aforementioned device being provided with a sheet feed, a cutting plate, d '' a waste ejection station, a reception station, as well as a device for separating the poses.
- Cutting devices of the aforementioned kind are known and used, inter alia, to cut with a cookie cutter in cardboard sheets the shapes (poses) corresponding to the desired product, to eject the cutting waste and to convey said poses to a reception from which these are sent to a device ensuring a subsequent operation.
- the object of the present invention is to eliminate this additional process and to obtain a mechanical separation and hence the reception of the separate cuts.
- This measurement could advantageously be carried out by being carried out in conjunction with the action of an existing device of the cutting machine so, therefore, having to have recourse to a minimum of stations in said cutting machine.
- the present invention relates to a device for cutting sheets of paper, cardboard or similar materials, the sheets being transformed into multiple poses, the aforementioned device being provided with a sheet feed, a cutting plate, a waste ejection station and a reception station, the routing of the sheets being provided by an appropriate transport device, characterized in that the reception station comprises a device for separating the blanks.
- the device for separating the blanks located in the reception station comprises an upper part, essentially movable, in the vertical direction, and a lower part, the upper part having counterparts according to the configuration of the blanks to be separated and the lower part of the separation bars corresponding to the edges of the blanks to be separated.
- the upper part is pivotable in the vertical direction by hydraulic control.
- the accompanying drawing schematically illustrates, by way of example, a preferred embodiment of a device for cutting and separating the sheets, object of the present invention.
- FIG. 1 shows a schematic view of the device according to the invention
- fig. 2 shows the upper and lower parts of the device for separating the blanks, the lower part being an oblique view from above and the upper part, folded towards the top, being a view from below;
- fig. 3 schematically represents a section in accordance with line III - III of FIG. 2, the upper part of the waste ejection station being in the functional position;
- Fig. 1 is purely schematic and represents only the general arrangement.
- the supply of sheets 1 is designed such that a stack 2 comprising the sheets to be cut can be placed on a pallet 3 and, therefore, introduced directly into the device.
- a transport device (not shown), it is always the top sheet 4 which is carried from the stack 2 is appropriately aligned on a margin table 5 before being conveyed to the transport device 6.
- This device 6 is made up, in a known way, for example of endless transport chains 7 intended to grip the front edges of the sheets 4 in a known way using pliers bars and to pull them inside the machine.
- the number 8 has been assigned to the cutting plate from which the sheets 9 inserted are cut.
- These last sheets are then pulled into the waste ejection station 10 in which the waste (1 1) is detached from the sheet and intercepted by a container 12.
- the sheet which, at this stage, consists only of a series of interconnected poses, then arrives at the receiving station 13.
- This station 13 is arranged so as to allow the blanks to be received one on top of the other in the form of a stack 14 on the pallet 15. According to the present invention, provision is made for fitting the blanking device 16 above the receiving station, respectively inside the latter. The fact of separating the poses has as a consequence the separation of the sheet into different individual poses and the reception thereof in separate form on the pallet 15.
- the pose separation device consists of an upper part 17 and a lower part
- the lower part 18 is integral with the entity of the device thanks to the supports 1 9.
- the separation bars 21 have been arranged, the arrangement of which corresponds to the edges of the blanks to be separated. In the case shown, each sheet is separated into eight rectangular poses.
- the upper part 17 In its working position, the upper part 17 is arranged more or less parallel to the lower part (see fig. 3) and has counterparts 22 which protrude from the part 17 in the downward direction and has an external configuration more or less identical to that of the poses to be separated but in no case smaller than said poses.
- the shape of the separation bars 21 and the counterparts 22 shown in FIG. 2 is illustrated as a simple rectangle. However, said form can also be very complicated depending on the desired pose.
- the upper part 17 is in the raised position so that the transport device can pull the sheets with the poses 23 and 24 attached until the edges of the poses 33 are located above the dividing bars 21 respective. Then, the upper part is lowered, after which the counterparts 22 push the poses 23 and 24 downward through the lower part 18, which results in the separation of the poses along the edges of the poses 33. The poses thus separated fall to be received on the pallet 15 forming a stack 14. Taking their departure from the separation bars 21, the guide bridges extend downward as illustrated in an enlarged manner in FIG. 4. These guide bridges 25 give the separate poses some guidance up to the level of the stack 14 located below, so that this results in an orderly reception.
- the upper part 17 is raised again to free the way of the next sheet to be introduced.
- FIG. 5 schematically represents two examples of execution of the preferred technique.
- a lifting rod 26 is fixed to each corner of the part 17 and is attached to its upper end, by means of an axis 27, by means of an articulated pivoting lever 29. By the upward and downward pivoting of the lever pivoting, the lifting rod 26 and, consequently, the upper part 17 are raised and lowered at the desired rate.
- the professional easily realizes that the vertical movement of the part 17 can also be provided advantageously by other devices such as, for example, hydraulic cylinders connected directly to the lifting rods 26 or to the pivoting levers 28.
