Definitions
- the invention relates to a stack cutting device with a support element.
- Stack cutting devices which have a lowerable upper blade and a stationary lower blade. This separates stacks of blanks from stacks of sheets.
- a cutting edge of the upper blade must be lowered at least a little below a cutting edge of the lower blade so that the cutting process can be carried out completely.
- the part of the bottom sheet that protrudes beyond the lower blade can be bent downwards. If the cutting edge of the upper cutter is guided past the cutting edge of the lower cutter, the bottom sheet can be folded over around the cutting edge of the lower cutter, particularly in the case of thin sheets. This can result in the bottom sheet not being cut cleanly, but only scraping off a layer, for example. Then a part that actually needs to be separated remains on the bottom sheet and causes problems during further processing.
- a stack cutting device with a cutting device is known from EP 1 018 408 A1, which has a ruler that can be pivoted about an axis, by means of which a separated stack of blanks can be kept in shape laterally when it is erected after a cutting process.
- DE 102009 053 975 A1 discloses a stack cutting device which has a movable protective element which is intended to prevent cut paper strips from reaching a front table and which can also be used to push partial stacks onto the front table after the cut.
- a stack cutting device is known from DD 62 300 B1, in which a stack of sheets is transported across a cutting gap in order to be cut by an upper cutter arranged behind the cutting gap and interacting with a cutting bar.
- a pivotable bridge element is arranged in the cutting gap.
- a device for cutting stacks of books is known from DE 3829682 A1. This has a cutting bar that interacts with an upper blade that is arranged behind a cutting gap. A pivotable bridge member is positioned in the cutting gap.
- FR 1 150 136 A discloses a stack cutting device which has an upper blade which interacts with a cutting bar. In the area after the knife, the stack support surface folds down to create a gap through which waste pieces can be disposed of.
- US Pat. No. 3,913,750 A and US Pat. No. 3,146,650 A each disclose a device for cutting books, which has an upper cutter and a lower cutter with a cutting edge.
- the knife is arranged after a gap in the transport direction.
- the gap can be covered by a pivoting bridge element.
- DE 33 02 946 A1 and DE 35 13418 A1 each disclose a device for cutting books, which has an upper blade which interacts with a cutting bar.
- the knife is arranged at the rear end of a cutting gap.
- a bridge element for transporting the books across the cutting gap is arranged.
- WO 91/00168 A1 and US 2007/0227323 A1 each disclose a device known for cutting stacks of sheets, which has an upper blade that interacts with a cutting bar. According to WO 91/00 168 A1, cut material is transported away with a linearly movable table. US 2007/0227 323 A1 has a bridge element that has to be open during cutting in order to transport away the cut material.
- the object of the invention is to provide a stack cutting device with a support element.
- a stack cutting device has at least one, in particular first, cutting device for cutting at least one stack of sheets, in particular a cutting device for cutting stacks of sheets into stacks of blanks.
- the stack cutting device has at least a first front support device with a first front stack support surface.
- a first at least temporarily horizontal table level contains this first front stack support surface at least partially and preferably completely.
- the in particular first stack cutting device preferably has at least one first rear support device with a first rear stack support surface.
- a cutting gap is preferably arranged between the first front stack support surface and the first rear stack support surface.
- the in particular first stack cutting device has at least one movable upper blade and at least one in particular stationary lower blade.
- the undercutter preferably has a cutting edge.
- the first cutting device preferably has at least one first cutting aid for fixing sheet stacks in place, which is arranged such that it can be moved at least with respect to a vertical direction and which is arranged in front of the first upper cutter along a transport path provided for transporting sheet stacks and/or intermediate stacks and/or blank stacks.
- the in particular first pile cutting device has at least one movable support element which has at least one contact surface provided for supporting sheets in particular from below and which is arranged to be movable at least between a support position and at least a first disposal position, for example switchable, in particular pivotable.
- the at least one contact surface of the support element is arranged in and/or below the first table level when the support element is arranged in the support position.
- the at least one contact surface of the support element is arranged closer to an in particular stationary and/or lower cutting edge of the inner cutter when the support element is arranged in the support position than when the support element is arranged in the disposal position.
- This offers the advantage that even a very short end of a bottommost sheet of the stack can be supported from below in order to prevent this end from kinking when the upper knife is lowered and only partially scraped off instead of being separated cleanly.
- it can be ensured that the end of the sheet does not accidentally get into a gap during feed, which is necessary to create space for the upper knife.
- the at least one contact surface of the support element is preferably arranged at least partially and more preferably completely below the first table plane.
- the stack cutting device is characterized in that the support element is pivotable about a switching axis. This offers the advantage that a relatively simple movement is carried out and only a small amount of space is required.
- the stack cutting device is preferably characterized in that the first cutting device has at least one bridge element, which is in particular different from the support element and can be moved between at least one transfer position and at least one interruption position.
- the bridge element preferably has at least one support surface. It is preferred that when the bridge element is arranged in the transfer position, its support surface preferably lies completely in the first table plane and/or has a vertical normal vector. When the bridge element is arranged in the interruption position, its support surface is preferably at least 50%, more preferably at least 75%, even more preferably at least 95% and even more preferably at least 99% outside of the first table plane and/or has a normal vector that is derived from a vertical direction. This offers the advantage that even those components of the stack of sheets that are to be separated and processed further can be properly transferred to a next support surface and the advantages of the support element nevertheless remain.
- the stack cutting device is preferably characterized in that the at least one bridge element is arranged such that it can pivot about a pivot axis. This offers the advantage that a relatively simple movement is carried out and only a small amount of space is required.
- the stack cutting device is preferably characterized in that the at least one support element and the at least one bridge element are rigidly connected to one another and/or can be pivoted together about the switching axis. This offers the advantage that only one drive system is required to carry out both movements.
- the stack cutting device is preferably characterized in that the first cutting device has at least one shielding element that can be moved between at least one shielding layer and at least one release position.
- the shielding element When the shielding element is arranged in its shielding layer, the shielding element is preferably at least partially above the first table plane arranged. When the shielding element is arranged in its release position, the shielding element is preferably arranged completely below the first table plane. This offers the advantage that waste pieces only in designated areas occur.
- the at least one shielding element is preferably arranged rigidly relative to the at least one support element and/or rigidly relative to the at least one bridge element. Then again a common drive can be used.
- the stack cutting device is preferably characterized in that a surface normal of the contact surface of the support element encloses an angle with a surface normal of the support surface of the bridge element which is at least 30°, more preferably at least 45°, even more preferably at least 60° and is even more preferably at least 80° and is at most 150°, more preferably at most 135°, even more preferably at most 120° and even more preferably at most 100°.
- the stack cutting device is preferably characterized in that the at least one support element is arranged at least in its support position and more preferably always in particular along a transport path provided for sheet stacks between the first front stack support surface and the first rear stack support surface. As a result, only a small amount of space is required.
- the stack cutting device is preferably characterized in that the first stack cutting device has at least one lowerable cutting aid for pressing part of a respective sheet stack against the first front stack support surface and/or that the first stack cutting device has at least one lowerable hold-down device for pressing one in particular part of a respective stack of sheets to be separated against the first rear stack support surface. This enables a particularly clean cut.
- the stack cutting device is preferably characterized in that a guide surface for influencing a fall path of separated stack components is arranged below the outer cutter. Waste pieces can then be transported particularly easily along a path provided for them, for example into a waste container.
