Definitions
- the invention relates to a feeder and a method for a sheet-fed printing machine with a Device for at least partially arching a stack of sheets at least in its upper area and by at least two Adhesive elements which are spaced apart on the surface of the Sheet stack are arranged and temporarily on the top sheet in such a way act that it is pushed together or pulled apart and thereby a space between him and the next one Arch arises.
- the feeder of a sheet-fed printing press has the task of working on a Separate sheet support plate and pre-stacked sheets successively to the system of the printing press.
- the top sheet of the stack pneumatically by several suction cups attached to a rod on the Leading edge raised and then from Feed grippers or transport rollers taken over. These lead the bow individually for the installation of the printing press.
- By adjusting the suction power by changing the tilt of the suction rod and by the action of The single sheet feeder can blow air against the front edge of the stack adapted to different paper thicknesses and qualities become.
- a new bow to be isolated Therefore with a single sheet feeder the separation process very much go quickly to the desired machine speed to reach.
- scale feeders are used, where the sheets are fed through a suction head at the rear edge of the stack be isolated.
- On Scale feeder has various pneumatic separators and Drag vacuums that remove the top sheet and then it feed continuously to the system table.
- various Blowers, scraper brushes, scraper plates and sheet retainers attached which have the task of a trouble-free separation ensure and for a quiet, straight transport of the sheets worries that are overlapped on a system table.
- each sheet is aligned precisely. Either the blowing and suction air as well as the other aids mentioned must can be set by the printer precisely to the respective substrate.
- DE 32 11 371 A1 describes a device for separating and transporting sheet-like material, in which the top sheet is arched on the stack by resting the sheets on an arched base.
- the top sheet is tightened by means of clamping bodies, by changing the distance of these clamping bodies while they are in contact with the top sheet.
- the top sheet is then transported away in the direction perpendicular to the tensioning direction.
- a deflector on the front edge of the stack lying in the transport direction serves to hold back the sheets that have not been tightened.
- the clamping bodies can also be designed such that they are rotatable about an axis parallel to the direction of punishment of the top sheet or about an axis perpendicular to the transport direction of the top sheet.
- the invention has for its object to provide a sheet feeder and a method for sheet separation, which have a high working speed and reduced effort for suction and blowing devices and reduced air consumption.
- the feeder according to the invention for a sheet-fed printing machine with a Device for at least partially arching a stack of sheets at least in its upper area and by at least two Adhesive elements which are spaced apart on the surface of the Sheet stack are arranged and temporarily on the top sheet and thus on the sheet stack act that the top sheet is pushed together or pulled apart and thereby a gap between it and the next one Arches, is characterized in that the adhesive elements by one Axis are rotatably mounted, which is transverse to the front edge of the sheet or Trailing edge of the sheet, at least one adhesive element (7, 17) is drivable.
- the stack of sheets lying on a sheet support plate is bulged, preferably in that the sheet support plate is not flat becomes.
- a concave shape of the sheet stack at least in the upper area can alternatively z. B. also achieve that on the sides of a flat the stack of sheets lying on it attack the carrier partially raise. It is sufficient if the curvature on the Machine side or on the side of the machine facing away from the machine Sheet stack is generated. If a convex curvature under certain circumstances the curvature can be desired exploit that a sheet stack often has on its own.
- the Side of the sheet stack facing the printing press can e.g. B. grippers are provided which the Detect the leading edge of the sheet.
- the grippers pull the top one Sheet from the sheet stack, the remaining sheets by a Be held back and handed it over to the Press. Because the adhesive elements only the top sheet have partially lifted from the stack of sheets is its location in the The moment of detection by the grippers is precisely defined. Therefore, the transfer can take place without a stopover, e.g. B. on Transport rollers that register the sheet in one go to convey the printing press. This will make the movement equalized, and the machine speed can increase become.
- the sheet stack is not on the front, but is arched in its rear area.
- the Adhesive elements raise the top bow in its rear Area from the stack, and into the resulting space one or more touch fingers can be inserted, which hold the remaining sheets. This can be at the back the sheet stack and / or in the rear area of its sides be performed.
- Printing press can e.g. B. rotating friction wheels used become. Before the sheet is completely pulled off the stack is, the finger or fingers can be released, the next sheet can be lifted with the help of the adhesive elements and the finger or fingers can be brought back into position to feed the next sheet.
- the bow can the printing press thus closely or even successively staggered feed. Still there is enough time for the moving components, their different positions take. Therefore, the sequence of movements can be designed in this way be that only very small accelerations of the components occur. This allows the moving components and their Drives are dimensioned weaker, and vibrations are reduced.
- a particularly advantageous development of this Embodiment consists in that such a touch finger, holding the rest of the sheets, one at the same time Back pressure device for a friction wheel forms.
- the top one Bow is between a low-friction, for example polished surface of the touch finger and the friction wheel jammed, and the friction wheel transports the sheet reliable and practically slip-free to the printing press.
- the coefficient of friction between the friction wheel and the sheet much larger than the coefficient of friction between the Bow and the touch finger, the trigger behavior remains on constant for a long time.
- the adhesive elements that stretch the top sheet or contract, z. B. be movable fingers that reach from the side over the sheet stack and at their ends Wear adhesive surfaces.
- the adhesive elements are continuous or intermittent driven friction wheels, the surfaces of which are the adhesive surfaces form and press the spring against the top of the sheet.
- Friction wheels So that the friction wheels or other adhesive elements transport do not hinder the raised sheet to the press, can be lifted in the machine cycle and back on the Bow can be lowered.
- Friction wheels This effect can also be achieved with friction wheels achieve the eccentrically and synchronously with the Machine cycle are driven.
- the embodiments described above are completely without Air get along and can be operated accordingly and inexpensively are low-noise, are also embodiments with a limited use of air is conceivable.
- the top sheet instead of by friction rollers also by one Drag vacuums are pulled from the stack, leaving the rest Sheets are reliably held on the stack.
- suction rollers can also be used be that have a porous shell and in which a There is negative pressure so that the sheet adheres to it.
- the Intervention in the space between the top two Arch can also be supported by air or air if the flow dynamics allow it.
- For the initial separation of the sheets, for the conventional Investment systems require a lot of air, but is in none or very little air in all of these embodiments required, and the number of suction or Blowers is less.
- the feeder shown in Fig. 1 to 6 contains one in height movable sheet support plate 1 and one on the Sheet support plate 1 sheet stack 2 lying thereon.
- the sheet platen 1 is in its front and middle Area just. In the area of the two rear, d. H. of the Printing machine facing corners of the sheet platen 1 is the top of the sheet platen 1 formed so that them from the flat area towards the corners increases.
- the sheet support plate 1 thus has at least one partially concave top.
- the one on the Sheet support plate 1 resting sheet stack 2 takes in essentially the same shape so that the two rear, upper corners of the sheet stack 2 higher than its rest Surface.
- a friction wheel 7 in the area of the two rear corners arranged, which has an axis 8 which is parallel to extends the side edges of the sheet 6.
- the friction wheels 7 are by means not shown resilient towards the Top of the top sheet 6 biased, being can deflect resiliently upwards.
- the location of the friction wheels 7 and thus the top edge of the stack can be shown by not shown Sensors are detected around the top of the sheet stack 2 by moving the sheet platen 1 in operation to keep the same height.
- the friction wheels 7 then press a defined force on the back corners of each top arc 6.
- the axes 8 of the friction wheels 7 are with Not shown drive devices for rotating the Friction wheels 7 connected.
- a feeler foot 9 arranged, which has an elongated finger 10, which is approximately parallel to the top of the sheet stack 2 runs.
- the feeler foot 9 is in the direction of the sheet stack 2 and movable away from it in the leaf plane of Fig. 2 is pivotable about a pivot point 11.
- you can the feeler 9 is linearly movable or about a pivot point be pivoted in the plane of the top of the Sheet stack 2 is.
- To move the feeler 9 are not shown drive means provided.
- friction wheel 12 between the two friction wheels 7 arranged, which has an axis 13 which is parallel to The rear edge of the sheet stack 2 extends.
- the friction wheel 12 is located just above the touch finger 10 of the Feet 9 when the foot 9 in the direction of Sheet stack 2 has been pivoted.
- the friction wheel 12 and its Axis 13 are from above in the direction of the sheet stack 2 or the touch finger 10 and movable away from it. For this Movement and rotation of the friction wheel 12 are not shown drive means provided.
- the top of the finger 10 is z. B. a polished Metal surface, which compared to the friction wheel 12 one low coefficient of friction compared to sheet 6 having.
- the top sheet 6 is in front Pushed towards the transport rollers 3.
- the friction rollers 7 by not shown Meanwhile be lifted off the sheet 6. It but it is also conceivable that the bias of the friction rollers 7th is so small that sheet transport is not hindered.
- the length of the finger 10 or the distance of the Transport rollers 3 from the sheet stack 2 are chosen so that the top sheet 6 in time from the transport rollers 3 is taken when he between the friction wheel 12 and the Touch finger 10 exits.
- Tensioning the top bow and reaching into the resulting space can not only at the Trailing edge are performed, but alternatively or additionally on the side edges. Furthermore, it can at the Leading edge of the sheet can be carried out as below 7 will be described.
- a sheet stack is 15 in its front area concave by a appropriately curved sheet support plate 16 is used.
- Two friction wheels 17 correspond in structure and function to the Friction wheels 7 of the previous embodiment, however arranged above the front corners of the sheet stack 15.
- On or several grippers 18 are on a rotatable gripper bar 19 attached, which is arranged in front of the sheet stack 15.
- the grippers 18 pivot to the front edge 21 of the top sheet 20, take the sheet 20 on the Leading edge 21 and pull it from the sheet stack 15 to him to be fed to a printing press.
- the remaining bows will be retained by a front stack stop 22, over the top sheet 20 is lifted away when the space 23 between the top two arches is formed. It can also be located next to the front Stacking stop 22 wiper springs or wiper brushes be provided.
- Fig. 7 does not allow quite as high Working speeds like the previous one Embodiment, since the sheets do not overlap from Sheets of sheets can be removed.
- the masses are also kept low leave so that the working speeds more conventional Single sheet feeders can be easily reached or surpassed can without excessive accelerations and the so accompanying vibrations occur.
- the Separation of sheets by tensioning the top sheet much more reliable, with much less effort and with much less noise than a conventional, single sheet feeder working with air.
