Description

  • The invention relates to a sheet processing machine with a sheet braking device according to the preamble of claim 1 and a method for braking sheets to a stop according to claim 8.
  • State of the art
  • Sheet processing machines usually have a feeder, work stations, and a boom. From a stack of sheets in the feeder, an uppermost sheet is separated and transferred to a transport system. The transport system transports the sheet through the processing station to the delivery. A well-known transport system are rotating gripper carriage. These each consist of a cross bar, are attached to the gripper, with which the sheet is gripped at its front edge and the ends are attached to a lateral chain hoist, which guides the gripper carriage through the machine. For processing and delivery, the sheet must be braked to a standstill. This happens on the one hand by braking the gripper carriage and in addition by further sheet brakes. The sheet-processing machine can be, for example, sheet-fed presses or, in particular, sheet-punching and embossing machines. Such a machine is by the US 2,829,890 A disclosed.
  • As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the practices practiced in print finishing, such as punching with punch, corner punching and register punching are counted to this area. The punching takes place against a punching pad or against stamp, in some cases it is also shearing operations (vg. Postpress, training manual for bookbinders, Bundesverband Druck e. V. 1996, p. 351 ff .). Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format. When punching but also creasing lines or blind embossing in the Benefit be introduced. This complex process makes it indispensable to punch the sheets individually. Since the end products are sophisticated packaging in terms of technical and graphic design (such as packaging for cosmetics, cigarettes, pharmacy, food, etc.), special requirements are not only placed on the packaging materials themselves, but are also punching tools for optimum results required with the smallest tolerances and extremely precise and reliable punching machines. Flatbed punching best meets these demands. The printed sheets stacked on a pallet are fed to the punching machine. In the machine, the sheets to be punched are precisely aligned in an alignment device, taken over by a gripper carriage and positioned exactly in the punching device between a fixed undercounter and a vertical over a knee lever or eccentric upper table.
  • Such a flat bed punch is for example from the DE 30 44 083 A1 known. The two tables are equipped with cutting and scoring tools or corresponding counter tools with which punched out of the cyclically guided between the table surface sheets the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designated Nutzentrenneinrichtung.
  • Both in the stripping station and in the blanking station with sheet delivery, the sheet must be braked from transport speed to standstill. Since the sheet weakened from the previous cut arrives at the stations at a high speed, the sole deceleration of the front gripper bar may cause the rear part of it to be pushed open, a so-called "bulging" of the sheet. This is to be prevented by additional braking devices which act on the surface of the sheet. The streamlined sheet can then be processed with higher accuracy or stored edge to edge.
  • Various types of sheet brake devices are known in the art.
  • The EP 1 108 671 A2 shows a sheet brake system for a boom of a sheet-processing machine with a circulating brake band. The brake band has a suction area, which exerts a suction effect on a bow to be braked. The brake band undergoes periodic deceleration and acceleration phases, ie it is clocked with the sheet transport. During the duration of a deceleration phase of a bow, the brake band of the brake band is covered by the sheet to be braked.
  • The DE 42 18 421 A1 shows the sheet guide in the boom of a sheet-fed press. In this case, two gripper systems are used: a leading edge gripper system and a trailing edge gripper system, which each have sheet gripper for detecting the sheet edges. The simultaneous guidance of a bow on its front and its trailing edge makes it possible to transport and decelerate the bow without damage and safety.
  • In an alternative solution pneumatic sheet brakes are used, such as from DE 102 59 556 A1 known. These are located in the immediate vicinity of the bow and provide a negative pressure, which acts as a braking force on the moving past the pneumatic sheet brake arc. Pneumatic sheet brakes have the advantage over mechanical sheet brakes that the sheet surface is not affected, and markings can be avoided. The operation of pneumatic sheet brakes is based on the Venturi effect.
  • The DE 695 00 514 T2 shows, for example, a sheet brake device with brushes. The brake brushes are aligned obliquely to the sheet transport direction and exercise by applying a light braking force on the bow. The disadvantage is that this can cause marks on the sheet.
  • From the DE 10 2004 022 235 A1 , which is considered to be the closest prior art for claim 8, an apparatus for sheet deposition emerges in a sheet delivery of a sheet-fed press. The device has both acting on the entire width sheet brake, which acts frictionally, as well as a pickup gripper and a squeegee, which is located in the rear of the boom are located. Since the sheets are to be recorded and released again at different times depending on the operating state or material properties for optimal storage, the squeegee is arranged displaceably in the sheet transport direction. The problem with this embodiment of a sheet brake is that the squeegee is exposed to increased wear due to its displaceability. Another problem is that such a sheet brake can not be used in processing stations of a sheet processing machine, otherwise there is a collision of editing tools and squeegee. However, it is necessary to adapt the sheet brake to the sheet format in order to ensure that the sheet brake acts on the sheet until shortly before the sheet stops.
  • All known from the prior art sheet brake systems has in common that they are each located in the inlet area to processing stations and display and are thus mounted directly in front of Auslegefläche or editing tools. However, the lengths of delivery and processing stations do not always correspond in practice to the currently driven arc lengths. For example, under-sized sheets can not be braked to a standstill by the sheet brake systems since the sheets are transported at the front edge to a defined end position and are therefore no longer in the effective range of the sheet brake systems. In order to decelerate the sheets nevertheless to a standstill, they usually have to be braked strongly from the leading edge.
  • Object of the present invention is to develop a sheet processing machine so that sheets are passer accurate and gently stopped regardless of their format, and to provide a corresponding method.
  • This object is achieved with a sheet processing machine having the features of claim 1 and by a method for braking the sheet according to claim 8, wherein the sheet, in particular under-sized sheet are passer exactly stopped with a defined position of the sheet trailing edge.
  • In an advantageous embodiment, the sheet processing machine for processing sheets of paper, cardboard and the like has at least one processing station, a boom and a sheet transport system with rotating gripper carriage. If the sheet processing machine is a sheet punching and embossing machine, then the processing stations can be designed as a stamping station, breaking station and blanking station. The gripper carriages are driven by individually controllable linear drives. The processing stations and the sheet transport system are controlled by a common machine control. The sheets are transported by the sheet transport system from the feeder, from the rear end of the machine, in the sheet transport direction through the individual processing stations to the boom, the front end of the machine.
    A braking device is located between the leading edge of the boom and the stack trailing edge of the delivery pile. The leading edge of the boom is one of the station boundaries of the boom, namely the edge of the boom, which is first passed by a moving bow. The stack trailing edge of the delivery stack is formed by the sheet trailing edges of already deposited sheets.
    Depending on a braking device can continue to be located between the leading edge of a processing station and the trailing edge of a tool of a processing station. The leading edge of the processing station is one of the station boundaries of the processing station, namely the edge of the processing station, which is passed first by a moving sheet. The trailing edge of the tool of the machining station is the edge of the tool that is passed first by a moving sheet. For processing the sheet in one of the processing stations and for delivery in the delivery arm, the sheet is decelerated from its transport speed to standstill. In its holding position, the sheet is then processed or stored. The stopping position of a sheet can be described by the position of the gripper carriage during the sheet stop.
    A respective sheet is aligned in its holding position in the boom and / or its holding position in the at least one processing station with respect to its trailing edge. This is done by a respective sheet is transported by the linearly driven gripper carriage of the sheet transport system to a format-dependent holding position and by the braking device to the sheet stop of a respective arc acts on these. As a result, a "bulging" of the bow is avoided.
    By this orientation in the sheet processing machine according to the invention advantageously come to lie the sheet trailing edge of a respective sheet and the stack trailing edge of the delivery pile or the trailing edge of the tool a processing station above the other.
  • The sheet brake device may be formed in various alternative embodiments: As clocked sheet brake with circulating suction belt, as Hinterkantengreifersystem with rotating Nachgreifern for detecting the sheet trailing edge, as a pneumatic sheet brake with stationary suction, as a device with brake brushes or as an untimed sheet brake with permanently circulating suction.
  • Part of the invention is also a method for braking sheets to a standstill in a sheet processing machine, in particular of sub-sized sheet. Sub-format sheets are sheets which do not have the maximum sheet length allowed by the dimensions of the processing stations. In a first method step, the sheet format is determined by the machine operator. In a second step, he enters the sheet format in the machine control. These two steps can also be summarized by automation. The sheet format is determined by means of sensors and reported to the machine control. In a third step, the machine controller calculates the sheet holding positions of each sheet in the boom or the processing stations so that the sheet trailing edge of each sheet and the stack trailing edge of the delivery stack and the trailing edge of the tool of a processing station are superimposed. That is, there is an alignment of the sheet at its trailing edge. In a fourth step, the machine can be put into operation, wherein the linear drives of the sheet transport system of the sheet processing machine and located directly in front of the processing stations or the boom sheet brake devices are controlled by the machine control, that the sheets are each accurately slowed down in their sheet holding position.
  • The method can be monitored by the skilled person known sensors and the monitoring result are reported back to the machine control.

  • In FIG. 1 the basic structure of a sheet punching and embossing machine 100 for punching, breaking and depositing sheets of paper, cardboard and the like is shown. The punching and embossing machine 100 has a feeder 1, a punching station 2, a breaking station 3 and a boom 4, which are supported and enclosed by a common machine housing 5.
  • The sheets 6 are separated by a feeder 1 from a stack and fed and gripped by mounted on revolving chains 7 gripper carriage 8 with grippers at its front edge and pulled intermittently through the various stations 2, 3 and 4 of the punching and embossing machine 100 therethrough.
  • 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 supported vertically movable back and forth. In the inlet region of the punching station 2 is a sheet brake device 20, for example a Timed sheet brake with circulating suction belt. The inlet region of the punching station is understood to be the region between the inlet edge of the station and the rear edge of the punching tool.
  • The gripper carriage 8 transports the sheet 6 from the punching and embossing station 2 in the subsequent breaking station 3, which is equipped with breakout tools. In 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. In the inlet area of the breakout station 3 is a sheet brake device 20. The inlet area of the breakout station is understood to be the area between the inlet edge of the station and the trailing edge of the breakout tool.
  • From the stripping station 3, the sheet enters the boom 4, where the sheet is either simply stored, or at the same time there is a separation of the individual benefits. The boom 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 14 from the Area of the punching and embossing machine 100 can be moved away.
  • In Fig. 2a an arc 6 is shown in its holding position in a processing station 2, 3 according to the prior art. A gripped by grippers of a gripper carriage 8 with linear drive sheet 6 is introduced in the sheet transport direction F in the processing station 2, 3. As soon as the sheet leading edge BV reaches the braking device 20, it acts on a sheet 6 until the sheet trailing edge BH of the braking device 20 also passes. For processing the sheet 6 between the lower table 9 and upper table 10 or upper tool 18 and lower tool 19, the sheet 6 is aligned in the prior art at its leading edge sheet Paßgenau. Sheet leading edge BV and the leading edge AB of the tool of the processing station overlap. Between sheet trailing edge BH and the trailing edge EB of the tool of the processing station results in under-sized sheet 6 a distance. Ie. the brake device 20 does not act until the sheet stop on the sheet. 6
  • In Fig. 2b the holding position according to the invention of a sheet 6 in a processing station 2, 3 is shown. An incoming sheet in the sheet transport direction F 6, as soon as he reaches the braking device 20, braked by this. Since the sheet 6 is positioned for editing by undertable 9 and upper table 10 or upper tool 18 and lower tool 19 at its Bogenhinterkante BH register to the trailing edge EB of the tool of the processing station, the braking device 20 acts until the sheet stop on the sheet 6th Bogenhinterkante BH and trailing edge EB the tool of the processing station lie directly above each other.
  • The sheet holding position of a sheet 6 in its various processing stations 2, 3 and 4 is in Fig. 3 shown. It is clear that the trailing edge EB of the tool of a processing station and the sheet trailing edge BH in the processing stations 2 and 3 are each directly superimposed. In the delivery station 4, the stack trailing edge EA and the sheet trailing edge BH are also directly above one another. This ensures that the braking devices 20 can act in an ideal manner on the particular arc to be braked.
