Description

The invention relates to an apparatus and a method for separating adjoining benefits and waste of a punched sheet while the sheet is being moved in a transport direction, in particular for a sheet punching and embossing machine.

As punching the cutting is referred to as closed geometric blank forms, which can be arbitrarily shaped. The punching takes place against a punch pad or against a stamp, in addition to the actual punching but also creasing or embossing can be introduced into the benefit. Packaging materials, made of paper, cardboard, cardboard, corrugated board are mainly punched in sheet format, whereby due to the complex process sheets are individually punched.

In known punching machines, which can be designed both as a rotary punching machines, ie with a cylindrical punching tool, as well as flatbed punching machines with a flat punching tool, this punching machine, for example, fed to a pallet stacked sheets. In the machine, the sheets are first aligned in an alignment and taken over by a gripper carriage, which transports the sheet to the punch in the punching device on. Following the punching and other processing steps, the sheets are transported by the gripper to a device for breaking the benefit from the sheet and the subsequent Nutzentrennen. When breaking out the waste is removed by breakout. When Nutzentrennen is the Benefit separated from the waste.

Devices are known for breaking and Nutzentrennen in which the sheet is stopped in the device between an upper tool and a lower tool, which are each occupied by Ausbrechstiften. The congruent arranged Ausbrechstifte grasp the waste and push it through a breakout board, which break the breakpoints between benefits and waste. The setup of the stripping tool of the device must be done manually and individually for each sheet. The number of stripping pins can easily reach 500 pieces or more, whereby the time for setting up is enormous and the productivity of the sheet punching and embossing machine is impaired.

As a further development describes DE 10 2007 029 408 A1 a universal tool for sheet punching and embossing machines, which can shorten set-up times. The universal tool, which is suitable both for breaking and for Nutzentrennen, this has an assembly plate and a worktop, which are each provided with mutually aligned holes. Pins are plugged into these holes. The plates are separately height adjustable and each have a locking mechanism for clamping the pins. The universal tools can be associated with a breaking board or a Nutzentrenngitter, which are unmoved and adapted in their design to the distribution of the benefits of each sheet. Depending on the design of the stripping board or the Nutzentrenngitters the pins can be clamped in the worktop. As a result, the set-up time can be shortened, but the break-out board and the Nutzentrenngitter still be adapted to the respective punched sheet, which in turn occur long setup times.

Another tool-free device and a method for breaking and Nutzentrennen example, in US Pat. No. 6,467,382 B2 , which forms the basis for the preamble of claim 1, proposed. The benefit is separated from the waste during the movement of the sheet and the benefit is separated from the waste. For this purpose, the stamped sheet is transported to the device in a transport plane and guided between feed rollers arranged in pairs one above the other. The front edge of the transported sheet is detected and by a movable roller having a width across the entire sheet width transverse to the transport direction, the leading edge is detected and pressed down. When pressed down, the leading edge of the sheet is pressed by the movable roller to the lower of the paired feed rollers, whereby waste can be pulled down, while the benefits in the transport plane of pairs also superposed take-off rollers is transported on. For this purpose, the movable roller is moved completely below the transport plane, since otherwise the benefit could not be transported further. The disadvantage here turns out to be primarily the fact that the sheet in its leading edge region must have a disproportionately wide strip of waste in the transport direction, otherwise at typical transport speeds of two sheets per second would not be enough time to move the movable roller down without that already benefits against the roller. This affects the material economy.

There are also known devices for breakout and Nutzentrennen in which rollers whose width transverse to the transport direction is substantially smaller than the sheet width, are arranged so that they continuously deflect waste during the movement of the sheet down. Since the roles are rigidly arranged at the Designing the distribution of benefits on the sheet to be taken to ensure that on the sheet in the area of the roles always in the transport direction continuous web waste is taken into account, otherwise benefits through the roles is deflected downward, which also results in an unsatisfactory material economy. Sheets on which benefits in the transport direction undercut can not be broken on such a device.

It is therefore an object of the invention to provide an apparatus and a method which avoid the disadvantages known from the prior art, improve the material economy, and which allow waste and utility to be separated from those sheets which undercut benefits in the direction of transport ,

These objects are achieved by a device having the features of claim 1 and a method having the features of claim 8. Advantageous embodiments are set forth in the dependent claims and the description below.

Therefore, there is proposed a device for breaking and pay dividing of punched sheet adjacent to each other and use of a punched sheet, in particular for a sheet punching and embossing machine, while the sheet is moved in a transporting direction. The device according to the invention comprises a first transport device for transporting sheets along the transport direction in a first plane at a first speed with an endless first belt guided along deflection rollers and a hold-down means, wherein the hold-down means can be pressed onto the first belt. The device further comprises at least one breakout means for breaking benefit from the bow, the at least one breakout means being relative to the first Level nonparallel second level is pressed on the first band. The apparatus further comprises a first peeling means for removing the waste separated from the use in the second plane, wherein the first peeling means can be pressed onto the first band and a second transport means for removing useful in a third plane non-parallel relative to the second plane at a second speed with a guided along guide rollers, endless second belt and a second peeling means, wherein the second peeling means is pressed onto the second belt.

The device according to the invention is characterized in that the breakout means between a breaking position and a rest position away from the second level and to the second level is clocked movable.

According to the invention, the breaking-out means is arranged during the breaking of benefits from the sheet in a break-away position which is essentially tangential to the second level. The breaking-out means can touch the first band in the second plane. However, the breaking-out means can also be arranged at a distance from the second band in the breaking-out position. In one embodiment, the breaking-out means is embodied, for example, as a rotatable roller or roller, while in another embodiment it is designed as a type of sliding block, with sliding friction occurring between the sliding block and the waste.

If the breaking-out means is in the rest position, ie with a greater distance to the first band in the second plane than in the breaking-out position, then the breaking-out means, in the effective region of the breaking-out means transversely to the transport direction, during the transport in the transport direction from the first plane into the breaking direction third level pass unhindered, ie, for example, so that the benefits transported without contact on Ausbrechmittel over becomes.

It is expedient to arrange the first plane and the second plane relative to one another in such a way that the path between the breakaway position and the rest position becomes as small as possible under other constructive conditions, such as, for example, the removal of waste. The optimum range is between a congruent and a vertical arrangement of the first level and the second level. The smaller the distance between the breakout position and the rest position, the lower the time required to move the breakout means between these two positions. According to the invention, this results in the advantage that the sheet in its leading edge region can have a narrower strip of waste in the transport direction in relation to the prior art.

It is also advantageous according to the invention that the breaking-out means can be moved in clocked fashion. The clock is an arbitrary chronological sequence of oscillations of the Ausbrechmittels between the breaking position and the rest position. Conveniently, the stroke is adjustable so that the breaking-out means can be repeatedly reciprocated between the break-out position and the rest position during the breaking of benefits from a bow.

In one embodiment of the invention, an arc detector is arranged in the transport direction before the hold-down. The arc detector can be designed for example as an optical sensor in the form of a photodiode or acoustic sensor in the form of an ultrasonic sensor. Sensors based on other physical effects can be used according to the invention.

By means of the arc detector, the leading edge of a transported sheet can be detected. Then that can Breaking means are reciprocated with the specific time for the bow clock between the breaking position and the rest position. Accordingly, the detection of the leading edge of the sheet by the sheet detector performs the function of a trigger for triggering the predetermined by the clock movement of the Ausbrechmittels.

It is advantageous to arrange a plurality of breakout means transversely to the transport direction. As a result, the effective range of a breakout means is variably adjustable transversely to the transport direction. On the one hand, it is possible to use breaking-away means, each with different widths of effective areas transversely to the transport direction, on the other hand, the breaking-out means can be arranged transversely to the transport direction almost at any desired position. This is made possible by the fact that, according to the invention, no web which is continuous in the transport direction must be taken into account on the sheet in the effective region of the breaking-out means, since breaking-out means can be moved in a clocked manner between a break-out position and a rest position. According to the invention, use can thus be broken out of such sheets, which have undercutting benefits in the transport direction. For this purpose, it may be provided that the plurality of breakout means are each movable in mutually independent clocks.

It is appropriate that the first speed and the second speed have equal amounts. This is advantageous for the breaking and Nutzentrennen of, for example, cartons. Since there is no relative velocity between already partially broken benefits and waste, the break-out occurs only by deflecting the waste in the second level. If benefits from an arc with, in relation to the previous embodiment of the carton, greater material thickness are broken, but can also be provided that the amount of the second speed is greater than the amount of the first speed. As a result, in addition to deflecting waste from the first level into the second level, use can also be torn out of the waste in the transport direction, since there is a relative speed in the transport direction between use and waste.

Arc, utility and waste move due to the transfer of power from the first band to bow and drop and due to the transfer of power from the second band to the benefit. To increase the static frictional force between sheet, benefits, waste and the corresponding tape, it is useful bow, use and waste with an additional force to your own weight normal force to press the appropriate band. Therefore, in one embodiment of the invention, it is provided that forces with which the hold-down means and the first stripping means can be pressed in the direction of the first band and the second stripping means can be pressed in the direction of the second band are individually adjustable. For this purpose it can be provided that hold-down means and / or first stripping means and / or second stripping means can be pressed by means of a spring force in the direction of the first or second band. To adjust the spring force, for example, the bias of the spring, for example, a coil spring, will be changed.

Sheets may have different thicknesses depending on the use of their benefits. However, so bow, waste and benefits can be confiscated safely between holddown, first peel, second peel and the corresponding band can be provided in one embodiment of the invention that the size of an air gap between the hold-down means and the first band and / or between the first stripping agent and the first band and / or between the second stripping means and the second band is individually adjustable. The adjustable distance is preferably smaller than the material thickness of the sheet.

In one embodiment of the invention, the first stripping means is designed as a spring-mounted roller, wherein between this roller and the first band, an air gap is adjustable. The air gap is smaller than the thickness of the sheet. If there is no drop between this roller and the first band there is also an air gap between this roller and the second band. The diameter of the roller can be chosen in one embodiment of the invention so that in the presence of waste between the roller and the first band, the roller is also pressed against the second band. If the normal forces are sufficiently large, this can also transfer a force from the second belt to the roller and from the roller to the waste. It is therefore advantageous that the first stripping means is designed so that a frictional connection between the first band and the second band is adjustable.

By means of the device according to the invention, the required set-up times for the breaking and payload separation of another sheet, ie with a different distribution of use and waste, can be substantially reduced. For this purpose, only the Ausbrechmittel be placed transversely to the transport direction to intended positions and to select the necessary for the break-away cycles, for example, from a memory of a control device. In this way, in the control device, the positions of the breakout means and the respective clocks can be deposited for a plurality of different sheets. The operator of the device according to the invention can then by, for example, visual and / or acoustic Instructions the conversion of the device can be specified.

There is also proposed a method of breaking and pay dividing the punching line adjacent to each other and using a punched sheet while the sheet is being moved in a transporting direction.

The method thereby comprises transporting the sheet in a first plane, breaking the utility from the waste by deflecting the waste from the first plane into a second plane not parallel to the first plane and further transporting the waste to the second plane, and further transporting the utility into a third plane not parallel to the second plane. In this case, the deflection of the waste from the first level into the second level takes place by selective application of force to the waste at at least one stationary point of action, wherein the waste is transported past the point of action past along an axis parallel to the transport direction Einwirkspur due to its movement in the transport direction.

In principle, punching lines can be arranged in any direction on the sheet, with the benefit outwardly limiting punching lines, however, always form a closed curve on the sheet. In the prior art, a force can be generated for example by rigidly arranged rotatable rollers. Therefore, care must be taken in the design of the distribution of benefits on the sheet that on the sheet in the area of the force application point is always considered in the transport direction web waste, otherwise benefits are deflected by the force downward. Accordingly, an arrangement of punching lines transverse to the transport direction is impossible in the region of the web.

The method is characterized in that a force on the waste is terminated before the Influence trace intersects a punching line odd order and the force is again effected after the Einwirspur has crossed an even-order punching line.

With regard to the device according to the invention, the point of action remains stationary, since this point represents the point at which the selective application of force to the waste takes place. After termination and re-application of the force, the point of action is located at the same position with respect to the device of the invention as before the termination of the force.

By the proposed method, the material economy can be considerably improved, since the use of the method can be arranged on the sheet so that the proportion of waste on the sheet is minimized, so also that punching lines crossing Einwirspuren transversely to the transport direction.

In the case of traces of intervention of crossing punching lines, there is a defined number of punching lines for each engaging track, which intersect the action track of the point of action. Each lane may have a different number of cut lines crossing the lane. Contrary to the transport direction starting at the leading edge of the sheet, these can each be counted separately for each interaction track, so that punching lines of odd order, for example the first, third, fifth order and punching lines of even order, for example second, fourth, sixth order result.

By terminating the force on the waste before the reaction lane crosses an odd-order punch line, the benefit can be further transported from the first to the third level. If the interference track crosses an even-order punching line, the force effect is again effected, whereby waste again from the first to the second Level is distracted.

It is expedient that the leading edge of the sheet is detected in the first plane before the at least one point of action by an arc detector. The detection of the leading edge of the bow is a kind of trigger with which a temporal sequence of termination and again causing the force to the waste is triggered. This time sequence is called a clock.

It is expedient that a cycle of the force to be terminated and again to be effected is preset for the respective arc. As a result, not every punching line that crosses an intervention track needs to be detected individually. According to the invention, however, the recognition of punched lines by using a further sensor is possible.

To further increase the freedom of design when distributing the benefit on the sheet and thus the improvement of the material economy can be provided that the force effects are terminated at at least two parallel to Einwirkspuren Einwirkpunkten with independent cycles and again effected.

Fig. 1 and Fig. 2 However, both show a schematic representation of the same preferred embodiment of the device according to the invention in different states. While the breakout means 10 in Fig. 1 is arranged in a breaking position 18, the breaking-out means 10 is in Fig. 2 arranged in a rest position 19.

The device according to the invention can be used in particular in sheet punching and embossing machines. In this case, the device can be designed as a detachable from the sheet punching and embossing module or form a firmly connected unit with the sheet punching and embossing machine, which is for example dismantled only for transport purposes. Since breaking and Nutzentrennen the actual punching and / or embossing process time, the device according to the invention is the punching and / or embossing tool in the transport direction 4 of the sheet 3 downstream, with other assemblies of the sheet punching and embossing machine next to the device according to the invention actually in Fig. 1 and Fig. 2 are not shown.

In Fig. 1 and Fig. 2 on the left, a first transport device 5 and, to the right, a second transport device 13 are shown. While transported with the first transport device 5 of the sheet 3 of one of the device according to the invention upstream assembly of the sheet punching and embossing machine and the waste 2 is removed after breaking out, with the second transport means 13 a benefit 1 is removed. The first transport device 5 and the second transport device 13 can be designed as separate modules, so that the device according to the invention can be easily separated to perform, for example, maintenance or adjustment work on otherwise inaccessible areas of the first transport device 5 and / or the second transport device 13.

The first transport device 5 comprises a guided along deflection rollers 7, endless first band 8, wherein the first band 8 is shown only in sections, and therefore the representation of further deflection rollers 7 is omitted. The first transport device 5 also comprises a drive device, not shown, by means of which the first belt 8 is movable at a first speed.

The second transport device 13 comprises a guided along deflection rollers 7, endless second belt 15, wherein the second band 15 is shown only in sections and therefore is dispensed with the representation of further pulleys 7. The second transport device 13 also includes a non-illustrated drive means by means of which the second band 15 is movable at a second speed.

The first speed and the second speed are independently adjustable. Depending on which material or material combination of the sheet 3, the first speed and the second speed can be set equal or such that the second speed is greater than the first speed.

In the following, the device according to the invention and the method according to the invention are to be described with reference to FIG Fig. 1 and the Fig. 2 are illustrated, wherein the breaking and Nutzentrennes of a sheet 3 is explained during the transport of the sheet 3 by the device according to the invention.

After being punched and / or stamped, the sheet 3 which has been processed with a punching tool leaves the area of the punching and / or embossing tool of the sheet punching and embossing machine, which does not belong to the device according to the invention is added, and is disposed on the first belt 8 of the first transport device 5. The sheet 3 may have a plurality of transverse to the transport direction 4 arranged punching lines. The first belt 8 transports the sheet 3 at the first speed in the first plane 6. By means of the sheet detector 17, the leading edge of the sheet 3 is detected. This information is transmitted to a control device, not shown, of the device according to the invention.

As a result, the sheet 3 reaches the hold-down means 9, which may be formed as a roll, roller, ball or the like. The height-adjustable in relation to the first level 6 hold-down means 9 is spaced from the first band 8. Due to the height adjustability of the hold-down means 9, it is possible to react individually to different material thicknesses of sheet 3, so that their insertion into the hold-down means 9 is ensured. If the sheet 3 is retracted into the hold-down means 9, this exerts an adjustable force on the sheet 3 in the direction of the first plane 6. The force is adjusted to provide good adhesive contact between the sheet 3 and the first belt 8, i. the one for transporting the sheet 3 sufficiently strong static friction force arises. The hold-down means 9 is compared with a deflection roller 7 on the other side of the first belt 8, which is fixedly mounted, but rotatable.

As a result, the sheet 3 reaches the breaking-out means 10. Transversely to the transport direction 4, a plurality of break-out means 10 can be arranged next to each other. The number of breakout means 4 is limited only by their transverse to the transport direction 4 respectively required space and the maximum available width of the first band 8. The breaking-out means 10 is preferably designed as a roller or roller. In another embodiment, the Ausbrechmittel 10 but also be designed as a shoe. The breaking-out means 10 is arranged to be movable. By means of an actuator, not shown, the breaking-away means 10 can be moved away from the first band 8 and back to the first band 8. The actuator may for example be designed as a pneumatic, electrical, hydraulic or other actuator, which in turn is supplied with energy and is connected to the control device.

In Fig. 1 is the breakout means 10 in its breaking position 18, that is, zoomed to the first band 8, shown. In Fig. 2 By contrast, the breaking-out means 10 is shown in its rest position 19, ie moved away from the first band 8.

If the sheet 3 has reached the breaking-out means 10, the breaking-out means 10 detects the leading edge of the sheet 3 which has waste 2 across its entire width transversely to the transport direction 4 in the region of the leading edge and directs the waste 2 into a second plane which is not parallel to the first plane 6 11 off. The breaking-out means 10 is opposed on the other side of the first band, a deflection roller 7, which is fixedly mounted, but rotatable. All breakout means 10 are in the breaking position 18.

As the sheet 3 continues to move on the first belt 8, the waste 2 is deflected downwardly into the second plane 11, with the utility 1 moving further in the first plane 6 in the transport direction until it reaches the second belt 15 of the second transport 13 reaches a non-parallel to the second level 11 third level 14. Preferably, the third level 14 is disposed below the first level 6, as benefits 1 bend during transport from the first band 8 to the second band 15 due to its elasticity and the weight force acting on it.

If breaking-out means 10 are located in breaking-out position 18 and waste 2 is arranged between break-out means 10 and first tie-bar 8, this is possible by a selective application of force to waste 2 at a stationary point of action 20 during waste 2 due to its movement in transport direction 4 a parallel to the transport direction 4 Einwirkspur at the point of action 20 is transported past. If a breaking-out means 10 is located in the breaking-out position 18, no benefit can be transported from the first band 8 to the second band 15 in the area of the intervention lane of this breaking-out means 10, since the path through the breaking-out means 10 is blocked. Only benefit 1, which is arranged transversely to the transport direction 4 between breakout means or their wear tracks, can be transported from the first band 8 to the second band 15, if breakout means 10 are arranged in the breakout position 18.

As a result of the transport of the sheet 3 in the transport direction 4 and punching lines can approach the breakout means 10, which would cross the Einwirspur this Ausbrechmittels 10 in the further course. Contrary to the transport direction 4 starting at the leading edge of the sheet 3, intersecting punching lines for each tangential track can each be counted separately, so that punching lines of odd order, for example, the first, third, fifth order, etc., and straight order punching lines, for example, second, fourth, sixth Order, etc. result.

In order that the benefit 1, which is located opposite to the transport direction 4 behind a punching line of odd order, can be transported from the first belt 8 to the second belt 15, the force action on the waste 2 is terminated before the intervention track crosses a punching line of odd order and effects the force again is after the Einwirspur has crossed a punching line of even order.

As a result of the individual arrangement of the benefit 1 on the sheet 3, a separate cycle is produced for each lashing track of a sheet 3, the cycle being an arbitrary temporal sequence of reciprocating movements of the breaking-out means 10 between the breaking-out position 18 and the rest position 19. Thus, for the timing of an individual sheet 3 predeterminable and stored in the control unit, not shown. By means of the information deposited by the bow detector 17 in the control device that a bow approaches the breakout means 10, the breakout means 10 can then be actuated by means of the actuators, not shown, with the stroke of the respective breakout means 10 and the reciprocating movement of the breakaway means 10 can be effected.

Waste 2, which is further transported on the first belt 8, approaches due to a first stripping means 12, which may be formed as a roller. The height-adjustable with respect to the second level 11 first peeling means 12 is spaced from the first band 8 is arranged. Due to the height adjustability of the first stripping means 12, it is possible to react individually to different material thicknesses of sheet 3, so that their insertion into the first stripping means 12 is ensured. If the sheet 3 is retracted into the first peeling means 12, this exerts an adjustable force on the sheet 3 in the direction of the second plane 11. The force is adjusted to provide good adhesive contact between the sheet 3 and the first belt 8, i. the one for transporting the sheet 3 sufficiently strong static friction force arises. The first stripping means 12 is opposite to the other side of the second belt 15, a guide roller 7, which is fixedly mounted, but rotatable.

Benefit 1, which is transported from the first band 8 to the second band 15, approaches due to a second one Peeling means 16, which may be formed as a roll or roller. The second removal means 16, which is height-adjustable in relation to the third plane 14, is arranged at a distance from the first band 8. Due to the height adjustability of the second stripping means 16, it is possible to react individually to different material thicknesses of sheet 3, so that their insertion into the second stripping means 16 is ensured. If the sheet 3 is retracted into the second peeling means 16, this exerts an adjustable force on the sheet 3 in the direction of the third plane 14. The force is adjusted so that a good adhesive contact between the sheet 3 and the second band 15 is formed, that is, a sufficiently large static friction force for transporting the sheet 3 is formed. The second stripping means 16 is on the other side of the second belt 15, a deflection roller 7 faced, which is fixedly mounted, but rotatable.

The described method is repeated as a result of each transported sheet 3.

When changing to a sheet 3, which has a different distribution of benefits and waste, the device of the invention must be retrofitted. For this purpose, breakout means 10 can be freely positioned transversely to the transport direction 4. The number of breakout means 10 is variable and adaptable to the respective sheet 3. Only the extent of the breaking-out means 10 transversely to the transport direction 4 has a limiting effect on the maximum number of break-out means 10 that can be used. If the number and position of the break-out means 10 is changed, the cycles required for the break-out means 10 can be selected, for example from a memory of the control means. In this way, both the positions of the breakout means 10 and the respective cycles for a plurality of different sheets 3 can be stored in the control device.

Method for breaking off and separating finished product (1) and waste product (2) of a punched sheet (3), which are adjacent to one another on punching lines, while the sheet (3) is moving in a conveying direction (4), using a device according to one of Claims 1 to 7, characterized by the steps of

   - conveying the sheet (3) in a first plane (6),

   - breaking off the finished product (1) from the waste product (2) by deflecting the waste product from the first plane (6) into a second plane (11) which is not parallel in relation to the first plane (6), and onward conveying of the waste product (2) in the second plane (11),

   - onward conveying of the finished product (1) in a third plane (14) which is not parallel in relation to the second plane (11),

   wherein deflecting of the waste product (2) from the first plane (6) into the second plane (11) is performed by punctiform application of force on the waste product (2) at at least one stationary application point (20), and the waste product (2), on account of its movement in the conveying direction (4), is conveyed along an application track which is parallel with the conveying direction (4), past the application point (20), and wherein the application of force on the waste product (2) is terminated before the application track intersects a punching line of an odd order, and the application of force is renewed once the application track has intersected a punching line of an even order.
9. Method according to Claim 8, characterized in that the leading edge of the sheet (3) in the first plane (6) is identified ahead of the at least one application point (20) by a sheet detector (17).
10. Method according to one of Claims 8 to 9, characterized in that a cycle for the application of force to be terminated and to be renewed is pre-adjusted for the respective sheet (3).
11. Method according to one of Claims 8 to 10, characterized in that the applications of force are terminated and renewed at at least two application points (20) which are associated with parallel application tracks, in mutually independent cycles.
