Abstract
A device for conveying sheets through a printing machine which ensures the safe transport of the sheet exactly in the prescribed transport path, at a low material expense. The device for conveying sheets through a printing machine is provided with continuous conveyor belts running over deflection rollers, between which the sheets are held by frictional forces and guided one after the other, whereby to generate the frictional forces, rollers are provided which press the conveyor belts against each other along the conveyance path. The contact surfaces of the conveyor belts with the sheet have a surface coating made of a material with a high coefficient of friction relative to the material of the sheet.
Description
- This invention relates to a device for conveying sheets through a printing machine.
- In printing machines, sheets of different types, sizes, and characteristics are transported through the areas of the printing machine from sheet supply areas to output containers for the printed material. In the process, the sheets cover considerable transport distances, in the course of which the printing operation takes place. The sheets essentially move by conveyor belts or driven belts, which are tensioned around movable, driven rollers. An essential criterion during the transport of the sheet is a frictionless and error-free delivery while reducing errors due to shifting or slipping of the individual sheets or pages, i.e. the position and orientation of the sheet on the conveyor belt or driven belt. The safe transport of the sheet is especially jeopardized for small sheet formats, especially at the transfer areas between two belt systems, and for directional changes of a sheet path, for example during the transfer from a vertical to a horizontal sheet path. A possibility for safeguarding the transport path of the sheet is guiding the sheet on path distances on the tension rollers that are as long as possible, i.e. increasing the number of the tension rollers in the printer. A second possibility is increasing the coefficients of friction of the surfaces of the conveyor belts and in this way, increasing the certainty of the transport of the sheet.
- The mentioned second possibility is disclosed in the patent WO96/10778, which describes an improved separation coating for use in many elastomer structures, for example, printing rollers and belts. The coating includes a thin, stretched polytetrafluoroethylene skin attached to a substrate, with a permeable surface and an impermeable area that is exposed as a contact surface. This usage of two surfaces on a single thin coating makes available on the one hand, an excellent bonding with the substrate material, e.g. a silicon elastomer layer, and is on the other hand, highly insensitive to wear, and insensitive to chemical influences.
- Disadvantageous in the first possibility, among other things, is the high material and structural component requirement and as a result, a higher maintenance susceptibility. The second possibility is a multiple layer construction, whose manufacture requires many operating steps.
- The purpose of the invention is to produce a device for conveying sheets through a printing machine, which ensures the safe transport of the sheet exactly in the transport path provided, at a low material expense. According to the invention, a device for conveying sheets through a printing machine is provided, having continuous conveyor belts running over deflection rollers, between which the sheets are held by frictional forces and guided one after the other. To generate the frictional forces, rollers are provided which press the conveyor belts against each other along the conveyance path, whereby the contact surfaces of the conveyor belts with the sheet have a surface coating made of a material with a high coefficient of friction relative to the material of the sheet. In an especially advantageous manner, the surface coating can be made out of silicone.
- In order to clean the contact surfaces of the conveyor belts, to prevent soiling of the sheet and to ensure the coefficients of friction of the contact area, at least one cleaning device is assigned to the conveyor belts. This cleaning device can contain set cleaning rollers. Furthermore, at least one of the rollers that are present, which press the conveyor belts against each other along the conveyor path, can be constructed as a cleaning roller. For savings or to supplement the cleaning device, the surface coating of the contact surfaces has a surface that is anti-soiling. The sheet is held and guided in the center in the conveyor direction, whereby to support the edges that overhang out of the conveyor belts, guide elements are provided, on which the sheet lies horizontal to the floor during conveyance. As guide elements, plates, sliding rails, or traveling belts may be provided. Furthermore, during the horizontal conveyance of sheets, several modules are provided with conveyor belt pairs, whereby each module of the conveyor belt lying above is constructed shorter than the conveyor belt lying below, whereby the number of the rollers allocated to the upper conveyor belt is reduced by one relative to the number of the rollers allocated to the conveyor belt lying below. The deflection rollers of the conveyor belt lying above act as tension rollers and each are arranged between the deflection roller of the conveyor belt lying below and the roller adjacent to the deflection roller of the lower conveyor belt. The surface coating can be constructed only in partial areas of the contact surface of the conveyor belt with the sheet. In this way, a material savings is obtained based on the physical phenomenon that the frictional force is independent of the size of the contact area. Furthermore, the surface coating can be constructed advantageously in a strip shape or in the form of separate islands.
- The invention, and its objects and advantages, will become more apparent in the detailed description of the preferred embodiment presented below.
- In the detailed description of the preferred embodiment of the invention presented below, reference is made to the accompanying drawings, in which:
- FIG. 1 is a schematic diagram of two sections of conveyor belts of a printing machine with a sectional surface coating according the invention made of a material with a high coefficient of friction; and
- FIG. 2 is a schematic side view of a paper path in a printing machine with deflection rollers and cleaning rollers.
- FIG. 1 shows, in an exemplary manner, a section of a
conveyor belt 10 and a section of anotherconveyor belt 15 of a printing machine. Visible on theconveyor belt 15, asurface coating 20 made of a material with a high coefficient of friction relative to the material of the sheet has been applied in sections to the shaded areas on this side of theconveyor belt 15. The conveyor belt 15 transports, on its upper side, thesheet 5 in the direction of the arrow a. Aroller 30 is arranged below the section of theconveyor belt 15. Anothercontinuous conveyor belt 10 is arranged above the section of theconveyor belt 15, and above this, anotherroller 30 is arranged. Therollers 30 function for the so-called interlacing of theconveyor belts 10 and/or 15. - Below the
upper roller 30, a section of theconveyor belt 10 is shown in FIG. 1. This conveyor belt moves in the direction of the arrow a, i.e. in the same direction as the section of theconveyor belt 15. Bothconveyor belts sheets 5 between theconveyor belt lower roller 30 from below and the force F1 acts by the pressure force of theupper roller 30 from above. In the case presented, theconveyor belts upper roller 30 run in opposite directions. Therollers 30 are shown set apart at a distance for clarity in this diagram according to FIG. 1, but in operation, therollers 30 are arranged adjacent to each other, and press theconveyor belts - From the description above, it is clear that the
sheet 5 between therollers 30 at the nip, i.e. the respective support surface of a roller, is clamped in a narrow area perpendicular to the transport direction. Therollers 30 are depicted in FIG. 1 as circles in a side view for illustrative purposes, but they have, as usual, approximately a length corresponding to the width of theconveyor belts rollers 30 are constructed to be crowned; i.e., the circumference of therespective rollers 30 is larger in their middle than on their edge. By the rotation of therollers 30 and the pressure forces F1, F2, theconveyor belts sheet 5 are moved in the direction indicated by the straight directional arrow a. Thesheet 5 is held essentially by frictional forces on theconveyor belts conveyor belts surface coating 20 are applied onto theconveyor belts conveyor belts conveyor belt 15, thesurface coating 20 is located, as shown in FIG. 1, on its upper side, on which thesheet 5 lies. - In the
conveyor belt 10, the surface coating [not shown] is located, in this diagram according to FIG. 1, on the underside that faces thesheet 5. The material with the high coefficient of friction relative to the material of thesheet 5 is in this case silicone, an organic compound of silicon with oxygen or carbon. In laboratory tests, it was discovered that silicone is especially suitable as a surface coating forconveyor belts - In operation, the
sheet 5 lies exclusively on thesurface coating 20 made of silicone. FIG. 2 shows in a schematic diagram essential parts of the device forconveying sheets 5 through a printing machine with an arrangement ofrollers 30 anddeflection rollers 35. Acontinuous conveyor belt 10 is allocated to theupper rollers 30 anddeflection rollers 35, and acontinuous conveyor belt 15 is allocated to thelower rollers 30 anddeflection rollers 35. The twodeflection rollers 35 perrespective conveyor belt conveyor belts conveyor belt 10 is tensioned around theupper roller 30 anddeflection rollers 35 and theconveyor belt 15 is tensioned around thelower rollers 30 anddeflection rollers 35, and these move in the directions indicated by the directional arrows. Thesurface coating 20 made of a material with a high coefficient of friction relative to the material of thesheet 5 and thesheet 5 are not shown in FIG. 2. - The
conveyor belts deflection rollers 35 acting on them by a drive of one of thesedeflection rollers 35. Therollers 30 function for the so-called interlacing of theconveyor belts conveyor belts 10 and/or 15. The frictional forces are effective between theconveyor belts sheet 5 so that thesheet 5 resting on theconveyor belts conveyor belts sheet 5 can be effectively prevented and thesheet 5 runs through the transport path in an error-free manner, i.e. in correct orientation and position. - To clean the
conveyor belts surface coating 20 of soiling, set cleaningrollers 40 are provided on theconveyor belts cleaning roller 40 is located above and one below therollers 30 anddeflection rollers 35 with theconveyor belts rollers 40 can have their own drive, but are preferably driven by the movement of theconveyor belts rollers 40, thesurface coating 20 is cleaned during each revolution and its coefficient of friction is maintained. As an alternative, therollers 30 can be constructed as cleaning rollers. The number ofrollers 30 is reduced in the process in comparison to similar devices for conveyingsheets 5, since by the increased coefficients of friction between thesheet 5 and theconveyor belts rollers 30 is not necessary to ensure the safe transport in an error-free orientation without slipping or shifting of thesheet 5. - The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
