From the EP 1 726 430 B1 is a continuous press for pressing pressed material mats into pressed slabs, with press lower part and press upper part, in the lower press part and press upper part endlessly circulating steel press belts and with an inlet mouth. Heatable press plates are arranged in the press lower part and in the press upper part. To the press plates close to the inlet side projecting heatable inlet plates to form the inlet mouth. The steel press belts are supported on the press plates and inlet plates with the interposition of rolling rods, which are guided by means of an upper and lower Rollstabumlaufeinrichtung about orbits and enter the area of the inlet mouth between the steel press belts and the inlet plates. The Rollstabumlaufeinrichtungen have guide wheels and in the region of the inlet mouth Rollstabeinführungsräder. The rolling rods are guided by means of rotating over the pulleys and Rollstabeinführungsräder rolling rod chains with rod compensation game.

The invention has for its object to design a rolling rod Einlaufwerk, a roll bar carpet, a continuously operating press and a method of the type mentioned, in which, in particular due to the centrifugal force during the deflection occurring vibrations of the rolling rods reduced, preferably prevented, can be. In particular, while a component cost, assembly costs, maintenance and / or wear should be kept as low as possible.

This object is achieved according to the invention in the rolling rod input drive in that the at least one deflection device has no with respect to the deflection axis radially inner guide element with which the roll bar carpet can be guided radially inward. According to the invention, the guide of the roll bar carpet in the region of the at least one deflection only takes place radially outward. By suitable design of the at least one radially outer guide element of the roll bar carpet, which would like to maintain its original linear direction due to the centrifugal force, pressed against the at least one guide surface of the at least one radially outer guide element and deflected accordingly with this. In this way, the roll bar carpet can be performed on the desired track, with the at least one radially outer guide element, the formation of vibrations is prevented. On corresponding guide elements radially inward can be dispensed with consciously in this way.

Advantageously, the guide chains can run in respective axially spaced areas of the at least one deflecting device.

Advantageously, the roll bar carpet with respect to the deflection axis radially outside with at least one radially outer guide element are guided over at least a partial circumference with respect to the deflection axis. In this way, the roll bar carpet can be performed directly with the at least one radially outer guide element.

In an advantageous embodiment, at least one radially outer guide element of the at least one deflection device between axially opposite regions, in which the guide chains of the roll bar carpet can run, be arranged so that it can guide the roll bars of Rollstangenteppich radially outward. Due to the centrifugal force, the rolling rods are pressed radially outward in the region of the deflection with respect to the deflection axis. Since the rolling rods are each secured to their respective longitudinal axes with respect to their respective axially opposite ends of the corresponding guide chains, the amplitudes of any vibrations in the middle of the rolling rods would be greatest without appropriate guidance. Therefore, the invention provides to guide the rolling rods between the areas for the guide chains corresponding to the deflection axis radially outward and so support. Advantageously, the at least one radially outer guide element is arranged between the regions for the guide chains such that it forms sufficient support for the rolling rods in the region of the deflection. Thus, the rolling rods can be performed with the at least one radially outer guide member to prevent the formation of vibrations, in particular due to centrifugal force. A support can be done directly on the roll bars. In addition, mechanical loads on connections between the rolling rods and the guide chains, in particular of so-called bending bars, can be reduced.

In a further advantageous embodiment, at least one radially outer guide element of the at least one deflecting device can be arranged in an area in which one of the guide chains can run such that it can guide the corresponding guide chain radially outward.

In this way, a wrap angle with respect to the deflection axis can be limited to a maximum of 270 °. Thus, the roll bar carpet with the at least one guide surface undergoes no reversal of the direction opposite to its original direction. As a result, higher running speeds of more than 1 m / s, for example 1.5 m / s, can be achieved for the roller table carpet. Further, a subsequent deflection in the original direction of the roll bar carpet on the insertion side of the at least one first deflection viewed behind, in particular obliquely above or obliquely below, the deflection can be arranged. In this way, the Rollstangenteppich can be made shorter overall.

Advantageously, two imaginary parallel planes each with one of the deflection axes of two in the direction of the roll bar carpet successively arranged deflecting be spaced from each other so that the plane of the upstream deflection in the direction of insertion of the upstream deflection viewed in front of the subsequent deflection, wherein the imaginary Layers perpendicular to the said direction, in particular spatially vertical run. A distance between the two parallel planes may be greater than the respective distances between the deflection axes and the corresponding guide surfaces of the deflection devices. In this way, a reversal of the direction of the roll bar carpet can be avoided even if the two deflection provide an S-shaped course of the roll bar carpet.

In this way, the at least one roll bar carpet can be gently inserted into the insertion region of the at least one guide surface and guided along it.

Advantageously, the imaginary connecting plane between the at least one deflecting device and the deflecting device arranged upstream of the running rod of the rolling rod carpet can extend spatially horizontally. In this case, the angles are the same.

In a further advantageous embodiment, a curvature of the at least one guide surface of at least one radially outer guide element, viewed at least in a section in the running direction of the roll bar carpet, can decrease, in particular decrease continuously, in front of a lead-out area of the at least one guide surface. In this way, the roll bar carpet can be smoothly released from the at least one guide surface. The curvature can decrease continuously. Alternatively, the guide surface can also be designed in steps, so that their curvature decreases correspondingly discontinuously.

In a further advantageous embodiment, an imaginary execution tangential plane to the at least one guide surface of the at least one radially outer guide element and / or an imaginary connection plane between the at least one deflecting device and with respect to the running path of the roll bar carpet subsequent deflection by an angle in a plane perpendicular to the deflection axis of at least 0 °, in particular between 0 ° and 30 °, relative to a spatially vertical plane with the deflection axis of the deflection axis be inclined away. In this way, the following deflection device can be arranged in relation to the original running direction of the roll bar carpet in the insertion region of the at least one front deflection device behind, in particular obliquely above or obliquely below, the at least one front deflection device. A reversal of the direction of the roll bar carpet can be avoided. This way, the required length of the roll bar carpet can be reduced.

In a further advantageous embodiment, the at least one guide surface of the at least one radially outer guide element viewed in the running direction of the roll bar carpet can lead upwards spatially. In this way, the roll bar carpet can be additionally pressed due to gravity against the guide surface of the at least one radially outer guide member. In this way, the leadership of the roll bar carpet and / or the prevention of vibrations of the rolling rods can be further improved.

In a further advantageous embodiment, the rolling rod input drive can have at least two, in particular three, similar or different deflection devices, which are arranged one behind the other with respect to the running direction of the roll bar carpet. In this way, the deflection and guidance of the roll bar carpet can be better adapted to the structure of the press.

Advantageously, with respect to the deflection axis, axial distances between the at least one guide element and a nearest area in which one of the guide chains can run may be greater than about 1/7 of an axial distance between the two areas for the guide chains. It has been shown that can be dispensed with by the special choice of the axial position of the at least one guide element in a minimum distance of about 1/7 of the axial distance between the two areas for the guide chains on radially inner guide elements as an abutment. In this way, a component cost, assembly costs and wear of the components involved can be reduced accordingly. In particular, an attachment of the rolling rods on the guide chains can be mechanically relieved and therefore spared.

Advantageously, the rolling bars at their ends by means of so-called flexural rods about its longitudinal axis rotatable and / or axially displaceably mounted to be connected to the respective guide chains. In this way, the rolling rods can rotate and / or move in the axial direction. By the invention, the bending rods can be mechanically relieved and thus spared.

Advantageously, the at least one radially outer guide element project beyond an area around a vertex of the deflection of the roll bar carpet. In this way, the roll bar carpet can perform better with the at least one radially outer guide element in the change of direction during the deflection. Thus, the at least one radially outer guide element can better absorb the centrifugal forces acting on the roll bar carpet during the deflection and prevent the roll bars from starting to oscillate, in particular, oscillation waves forming on the roll bars. The roll bar carpet can be guided more gently in the deflection and out of this. On the roll bar carpet and the at least one guide element acting forces can be reduced as a whole. Wear and the risk of malfunction can be reduced.

A vertex of the deflection corresponds in the context of the invention a vertex-section axis of the corresponding guide surface with an imaginary radial plane, wherein the radial plane contains the deflection axis on the one hand and on the other hand a section axis of an imaginary insertion-side connection plane of the deflection with an imaginary side connection level of the deflection.

In this way, a more uniform support over the length of the rolling rods can be done. At the same time, the number of radially outer guide elements can be reduced.

Advantageously, an axial distance between the regions for the guide chains may be approximately between 2 m and 4 m, in particular between 2.5 m and 3.5 m. Accordingly, the length of the roll bars may be slightly shorter than the distance between the areas for the guide chains, so the distance between the guide chains. In this way, correspondingly wide roll bar carpets can be used.

Advantageously, at least one deflection device can have between one and five, in particular one or two, radially outer guide elements. In this way, the rolling rods depending on the axial distances between the areas for the guide chains, so depending on the length of the rolling rods, are guided and supported so that no vibrations.

Advantageously, a single radially outer guide element can be provided at an axial distance between the areas for the guide chains of up to 2.7 m. It has been found that this is sufficient to at least reduce the vibration behavior of the rolling rods, in particular to prevent.

Advantageously, when using a single radially outer guide element, it can be arranged in the axial middle between the regions for the guide chains. Thus, a support of the rolling rods can be done with minimal component cost.

Advantageously, two radially outer guide elements can be arranged axially spaced. In this way, wear can be reduced. Furthermore, a redundancy with respect to the guide elements can be achieved.

Advantageously, at a distance between the regions for the guide chains of up to about 2.7 m, two radially outer guide elements can be arranged at a distance of about 0.5 m from the axial center between the regions for the guide chains. In this way, wear can be further reduced and redundancy can be achieved with respect to the guide elements.

In this way, even with the use of longer rolling rods, so wider roll rod carpets, an effective in particular with respect to the vibration suppression radially outer guide can be ensured.

Advantageously, at least two deflection devices viewed in the running direction of the roll bar carpet can be arranged one behind the other so that respective radially outer guide elements can engage on different sides of the roll bar carpet. Alternatively or additionally, at least two deflection devices may be arranged so that respective radially outer guide elements can engage on the same side of the roll bar carpet.

Advantageously, at least two deflection devices can be arranged such that at least one radially outer guide element of one of the deflection devices can engage an inner side of the roll bar carpet and at least one radially outer guide element of the following on the path of the roll bar carpet deflection can attack on an outer side of the roll bar carpet. Depending on a previous guidance of the roll bar carpet, in particular with a roll bar spreader of the roll bar carpet device upstream of the roll bar inlet, the at least one radially outer guide element of the front deflection device on the outside of the roll bar carpet may alternatively engage the at least one radially outer guide element of the subsequent deflection device on the inside of the roll bar carpet Attack Rollbar Carpets.

Alternatively or additionally, at least two deflection devices may be arranged such that the respective radially outer guide elements of both deflection devices on the inside or the respective radially outer guide elements of both deflection devices can engage on the outside of the roll bar carpet. In this way, a total travel path of the roll bar carpet can be reduced via the deflections and thus a correspondingly shorter roll bar carpet can be used. With a shorter roll bar carpet Material can be saved in the guide chains, the roll bars and possibly the bending bars.

Advantageously, at least two deflection devices can be arranged so that the roll bar carpet can be guided in an S-shaped course. In this way, respective wrap angles can be increased. In the areas of wrap around improved leadership can be achieved.

Advantageously, an axial width with respect to the deflection axis of at least one radially outer guide element may be approximately between 35 mm and 45 mm, in particular 40 mm.

In the 1 is a longitudinal section of a continuous press 10 for the production of press plates, for example, material boards made of wood and / or other renewable agricultural products, such as chip, fiber, straw and Schnitzelplatten and plastic plates, in the area of a lower roll bar infeed 12 shown. The lower roll bar infeed 12 is spatially under an inlet mouth of the press 10 , The components of the roll bar infeed 12 are in the 2 to 3 presented in different perspectives and detailed views. The 4 to 6 show an upper roll bar infeed 312 the press 10 , The upper roll bar infeed 312 is located above the inlet mouth of the press 10 ,

Because of the better orientation are in the 1 to 6 the corresponding axes of an orthogonal XYZ coordinate system shown. The Z-axis extends spatially vertically, the The X-axis and the Y-axis are spatially horizontal.

Between an upper strand of the steel strip 14 and a lower run, not shown, of an upper endless steel belt becomes pressed material 18 in a production direction 20 through the press 10 conveyed and pressed to press plates.

Inside one through the lower steel band 14 Surrounded area is a lower roll bar carpet 24 arranged. The lower roll bar carpet device 24 comprises a lower endless roll bar carpet 26, which by means of the lower roll bar infeed 12 on the inlet side of the press 10 and a bottom roll bar spout, not shown, on the exit side of the press 10 each deflected.

The roll bar carpet 26 includes two endless drag chains 28 which are spaced and parallel to each other. Between the leadership chains 28 extends a variety of rolling rods 30 perpendicular to the guide chains 28 , The roll bars 30 may have with respect to their respective longitudinal axes an axial length of greater than 3.00 m, for example, 3.35 m. Exemplary here have the rolling rods 30 with respect to their respective longitudinal axes axial length of 2.65 m. The roll bars 30 are at their ends in each case via so-called bending rods, which are not shown in the figures, rotatably and axially slidably connected to the guide chains 28 about their respective longitudinal axes.

An upper run of the roll bar carpet 26 lies on a spatially lower side of the upper run of the steel strip 14 at. On the upper strand of the steel band 14 opposite bottom of the upper run of the lower roll bar carpet 26 is a pressing device in the form of a press plate 32 , Between the press plate 32 and the steel band 14 are the roll bars 30 inserted in each case. The circulation of the roll bar carpet 26 ensures the rolling support of the steel strip 14 opposite the press plate 32 ,

Above the upper run of the steel band 14 is the one in the 4 to 6 shown upper roll bar carpet device 324 arranged. A lower strand of an upper roll bar carpet 326 is at the top of the lower run of the upper steel strip. On top of the lower run of the upper roll bar carpet 326 is an upper press plate. Again, between the upper press plate and the upper steel band, the rolling rods are inserted in each case running. The circulation of the roll bar carpet 326 ensures the rolling support of the upper steel strip with respect to the upper press plate.

The lower roll bar infeed 12 comprises a total of three deflection devices 36, 136 and 236, which, in one direction 42 of the roll bar carpet 26 considered, are arranged one behind the other and so a walkway 44 of the roll bar carpet 26 in the area of the inlet mouth of the press 10 pretend. The walkway 44 is indicated for better clarity in the figures as corresponding curve.

The first deflection device 36 is located in a spatially lower area of the roll bar infeed 12 , With her is a coming from the roll bar spout, not shown, bottom run of the roll bar carpet 26 around an imaginary first deflection axis 46 turned upside down. The first deflection axis 46 extends perpendicular to the direction of travel 42 and parallel to the rolling bars 30 , in the embodiment shown, parallel to the Y-axis, ie spatially horizontal.

A with respect to the first deflection axis 46 axial width of the radially outer guide elements 48 is 40 mm each. The radially outer guide elements 48 lead the roll bar carpet 26 with respect to the first deflection axis 46 radially outside. The radially outer guide elements 48 grip on the outside of the roll bar carpet 26 at. The outside of the roll bar carpet 26 is the side, which is also on the upper run of the steel band 14 is applied. The inside of the roll bar carpet 26 is accordingly the side on which the press plate 32 attacks.

Two of the radially outer guide elements 48 are, as in the 3 shown between two with respect to the first deflection axis 46 axially opposite areas 50 arranged. In the fields of 50 each run one of the leadership chains 28 , With these two axially outer radially outer guide elements 48 become the leadership chains 28 with respect to the deflection axis 46 each guided radially on the outside.

As an introduction tangential plane to a guide surface according to the invention an imaginary plane is referred to, which runs tangentially to the guide surface on the insertion side, ie the side on which the roll bar carpet is inserted into the region of the corresponding radially outer guide element. Accordingly, the imaginary tangent plane is referred to as the executed tangential plane, which runs tangentially to the guide surface there on the delivery side, ie the side on which the roller bar carpet leaves the region of the corresponding radially outer guide element. In this case, the insertion tangential plane and the execution tangential plane each extend in a direction approximately parallel to the deflection axis of the deflection device.

The introductory tangential plane 62 is also at an angle 66 in a plane perpendicular to the first deflection axis 46 by way of example about -8 ° with respect to an imaginary connection plane 68 between the first deflecting device 36 and one concerning the walk 44 upstream, not shown last deflection of the lower roll bar spout inclined.

As an imaginary connecting plane between two deflection devices in the context of the invention, a level between the execution side for the roll bar carpet of the upstream deflection and an insertion for the roll bar carpet the downstream deflection means, in the optimally stretched, so straight running rod carpet extends its path. The connection plane extends in a direction approximately parallel to the deflection axis of the deflection device.

The connection level 68 For example, it runs parallel to the horizontal plane, ie parallel to the XY plane, so that the insertion tangential plane 62 around the angle 66 inclined to the horizontal. Thus, the execute tangent plane is 64 one with respect to the angle 60 reduced in terms of absolute angle with respect to the insertion-side connection plane 68 inclined.

A respective curvature of the guide surface 58 the radially outer guide elements 48 increases in the direction of travel 42 looks behind a crest 70 the deflection continuously. The vertex 70 is the range of maximum deflection. Behind the vertex 70 The curvature gradually goes into the execution tangent plane 64 above.

A vertex of the deflection corresponds in the meaning of the invention a vertex-section axis of the corresponding guide surface with an imaginary radial plane. Wherein the radial plane contains on the one hand the deflection axis and on the other hand a cutting axis of the insertion-side connection plane with the delivery-side connection plane of the deflection device.

The bar wheels 282 are at the same distances to each other and to the sprockets 280 arranged like the bar wheels 182 the second deflection device 136 , Between the teeth of the bar wheels 282 become the rolling rods 30 positioned and held while guiding. The sprockets 280 and the bar wheels 282 each form radially inner guide elements with which the roll bar carpet 26 with respect to the deflection axis 246 is guided radially inward.

Furthermore, the third deflection device has 236 over a total of four radially outer guide elements 248 , The radially outer guide elements 248 each have a guide surface 258 on which the third deflection axis 246 surrounded circumferentially by way of example over more than half the circumference. The radially outer guide elements 248 grab the outside of the roll bar carpet 26 at.

The straight guide elements 120 extend as in the side view in 1 shown, from the operating ends of the radially outer guide elements 148 the second deflection device 136 , these overlapping, up to the insertion-side beginnings of the radially outer guide elements 248 the third deflection device 236 , these also overlapping. The straight guide elements 120 are considered in the direction of the x-axis, as in the 3 shown to the radially outer guide elements 148 and 248 and the bar wheels 182 and 282 each offset.

The teeth of the bar wheels 282 make sure that the rolling rods 30 be positioned at the same distance from each other and so a uniform arrangement of the rolling rods 30 takes place. Radial outside is the Rollstangenteppich 26 on the roll bars 30 with the radially outer guide elements 248 guided.
