METHOD FOR SETTING UP AN INLET OF A PEELING MACHINE AND PEELING MACHINE

Description

[0001] The invention relates to a method for adjusting an inlet guide of a peeling machine, in which a product to be peeled is guided by means of the inlet guide in relation to a peeling head carrying peeling tools. The invention also relates to a peeling machine comprising an inlet area with an inlet guide, a peeling head carrying peeling tools, and an outlet area, wherein the inlet guide carries at least two guide rollers by means of at least one roller carrier each, and wherein at least one of the roller carriers is adjustable via at least one guide roller actuator.

[0002] Known peeling machines have a peeling head that rotates around a rotary axis or a machining axis and features an adjustment device for tool holders that rotate with the peeling head. Using this adjustment device, these tool holders, with the tools attached to them, are positioned relative to a workpiece so that the tools, for example, remove a layer of scale from a hot-rolled material, resulting in a metallically clean round stock after processing.

[0003] Such a peeling machine is described, for example, in DE 101 29 207 A1, in which an adjusting device that can be moved relative to a hollow shaft is arranged in the area of ​​a peeling head. Depending on the position of the adjusting device, tool holders or tools mounted on them are moved radially to a machining axis. This allows the tools to be individually adjusted to the diameter of the base material being processed.

[0004] Furthermore, a machine for peeling pipes and rods is known from DE 195 03 772 A1. In this process, peeling is carried out by several peeling tools rotating around the material being peeled, each tool being arranged on rod-shaped tool carriers. The tool carriers are mounted so as to be radially displaceable relative to a longitudinal axis of the material being peeled and are supported, among other things, against the inside of a conical bushing.

[0005] EP 2 420 350 A2 describes a peeling machine with a feed device, wherein the feed device is equipped with feed rollers for accelerating workpieces, in particular rods, tubes, bars, wires, cables or the like, wherein the feed rollers are each driven by means of a feed roller shaft and wherein at least one feed roller shaft is eccentrically mounted in a shaft receptacle.

[0006] Peeling machines are also disclosed in DE 41 22 948 A1, US 5,303,621 and DE 32 23 232 A1. However, only DE 41 22 948 A1 is of the same type, while DE 32 23 232 A1 and US 5,303,621 deal with a feed device and not with an infeed guide.

[0007] Peeling products are predominantly forged metallic semi-finished products that have been formed by pressure forming and exhibit a predominantly longitudinal direction. Due to this forming process, peeling products have comparatively coarse tolerances. This particularly affects surface tolerances and the straightness of the peeling product.

[0008] Deviations in the straightness of the peeling material result in a theoretical center of the peeling material exhibiting a curvature in the longitudinal direction of the peeling material.

[0009] Deviations in the surface tolerance of the peeling material, on the other hand, lead to differing distances between the theoretical center of the peeling material and the surface of the peeling material.

[0010] Since these two deviations ultimately occur in very different forms, there can be significant fluctuations in the material distribution of the peeled material along the longitudinal direction.

[0011] A peeling machine is used to produce a bright product or bright material, in particular bright steel or a similar semi-finished product, from the peeled material. This bright product is characterized by low surface shape tolerances and excellent surface quality compared to the peeled material. For this to be successful, it is essential that the peeling machine processes as much of the surface of the peeled material as possible by removing a chip.

[0012] The dimensional accuracy of the material being peeled determines how much volume per unit length the peeling machine must remove. If the material exhibits comparatively high deviations in its straightness and / or surface tolerances, then a comparatively high volume per unit length must be removed by the peeling machine.

[0013] Prior art peeling machines have a feed device in the area of ​​their peeling head, comprising a feed mechanism and an infeed guide. While the feed mechanism is designed to accelerate the material to be peeled in its longitudinal direction, the infeed guide is designed to guide the material relative to the peeling head. Such feed mechanisms can often be adjusted with regard to the desired feed speed of the material and the direction in which the material exits the infeed guide.

[0014] This allows manual intervention in the process parameters of the peeling machine to ensure that the material to be peeled runs centrally towards the peeling head and that the peeling machine is given sufficient time to remove the volume of material to be removed within the processing limits of the peeling machine.

[0015] Particularly when the volume of material to be peeled (i.e., machined) by the peeling machine is to be minimized, or when the shape tolerances of the material exhibit constantly varying deviations, this results in a disadvantageous increase in the effort required to adjust the process parameters of the peeling machine. This leads to an increased workload for the skilled worker monitoring the peeling machine.

[0016] The object of the present invention is to provide a method for setting up an inlet guide for a peeling machine and a peeling machine which, despite possible inaccuracies of the supplied peeling material, such as non-roundness in the cross-section or deviations over the length, enables the highest possible quality of the peeled peeling material.

[0017] The object of the invention is achieved by a method for installing an inlet guide for a peeling machine and peeling machines with the features of the independent claims. Further advantageous embodiments, possibly also independent of these, are found in the dependent claims and the following description.

[0018] From a first perspective, despite potential inaccuracies in the material being peeled, the highest possible quality of the peeled product can be achieved by using a method for setting up an infeed guide in a peeling machine. This method guides the product towards a peeling head carrying the peeling tools, provided that the infeed guide's effect on the product is regulated in such a way that the theoretical center of the product, relative to the peeling head and / or the infeed guide, remains as constant as possible along its length. Cumulatively, or...Alternatively, according to a second aspect, despite possible inaccuracies in the supplied peeling material, the highest possible quality of the peeled peeling material can be achieved by a method for setting up an inlet guide of a peeling machine, in which a peeling material is guided by means of the inlet guide in relation to a peeling head carrying peeling tools, if any deviations of the peeling material from its target guide position are measured and used to control the inlet guide.

[0019] In this context, "peeling material" refers to a semi-finished metal product that has a predominantly longitudinal orientation and is intended to undergo, or is undergoing, a peeling process. Peeling material is predominantly formed using a pressure forming process, particularly a forging process, and consequently typically exhibits relatively wide tolerance ranges with regard to surface tolerances and the straightness of the longitudinal axis. Furthermore, a metallic peeling material often has a layer of scale on its surface, especially if it was hot-formed. This latter characteristic alone can be a reason to subject such a material to a peeling process.

[0020] Particularly common items to be peeled are rods, pipes, poles, wires or cables, but especially also blocks, hollow blocks and similar semi-finished products that are to be further processed after peeling, for example by being cut into slices.

[0021] If the theoretical center of the peeling material is determined as a function of the longitudinal direction, a connecting line of the theoretical centers is curvilinear for the majority of peeling materials.

[0022] The cross-sectional shape of a peeled product is usually round or approximates a round cross-sectional shape.

[0023] In this context, a "peeling machine" is understood to be a machining machine that gives the material to be peeled a specific geometric shape by mechanically removing excess material in the form of chips. The objective of a peeling machine is to produce a bright product, such as bright steel, from the peeled material, which is free of any scale and is characterized by low surface shape tolerances and excellent surface quality compared to the unpeeled material.

[0024] The "peeling head" is preferably a part of the peeling machine which performs a rotational movement during operation of the peeling machine, which carries one or more peeling tools and / or which reduces the diameter of the product being peeled.

[0025] A "peeling tool" is therefore preferably a cutting tool that has a cutting edge. During peeling, or machining in general, the cutting edge of the peeling tool penetrates the material being peeled and removes chips.

[0026] In this context, the term "infeed guide" of a peeling machine refers specifically to the part of the peeling machine that guides the material to be peeled towards the peeling head. An infeed guide typically has at least one control variable that can be used to influence the orientation of the material from the infeed guide to the peeling head.

[0027] The respective "theoretical center of the peeling material" is preferably understood to be the point that forms the center of the largest possible inner circle of an infinitesimally thin peeling material cross-section.

[0028] A "deviation of the material being peeled from its intended guide position" then preferably refers to the distance of the theoretical center of the material being peeled from the center of the orbit of a cutting edge of a peeling tool on the peeling head.

[0029] A "control system" is understood to be a process in which a variable quantity is, in principle, automatically kept constant or nearly constant. A characteristic of a control system is that the value of the quantity to be kept constant is determined as the actual value, and if it deviates from the desired setpoint, the value of a manipulated variable is adjusted so that the value of the quantity to be kept constant approaches the setpoint again. A suitable manipulated variable can be, in particular, a variable of the inlet guide. Specifically, the longitudinal extension of a guide roller actuator should be considered as a manipulated variable of the inlet guide.

[0030] A human can make adjustments by detecting a deviation between the actual value and the target value and changing the value of a manipulated variable at an actuator.

[0031] Alternatively, and preferably, control can be fully electronic, whereby an actual value is acquired using a measuring device, compared with the setpoint using a data processing and evaluation unit (electronically or electrically), and any deviation is converted into a manipulated variable value. This manipulated variable value is then transmitted to an actuator, which is configured to adjust the manipulated variable based on an electronic value input. In the latter case, the actuator must have a drive mechanism or other controllable actuating device.

[0032] The previous state of the art involved a skilled worker monitoring a peeling machine and, if necessary, adjusting the infeed to achieve a subjectively perceived improvement in the peeling result. Such interventions by the skilled worker were particularly necessary when the blank material to be produced had surface defects. Specifically, this included situations where the blank material still had scale on its surface in places.

[0033] Furthermore, the state of the art stipulated that the skilled worker would make an adjustment to the inlet guide if the volume to be machined was unevenly distributed around the circumference of the material being peeled.

[0034] In other words, when setting up the peeling machine, the skilled worker can only rely on qualitative information about the position of the material to be peeled.

[0035] In the current state of the art, the skilled worker has no way of quantitatively assessing a deviation between the theoretical center of the product being peeled in relation to the peeling head or a deviation of the product being peeled from its intended guide position during the ongoing operation of the peeling machine.

[0036] Peeling materials whose connecting line of the theoretical centers is curved require increased effort for regulating the guide position of the peeling material to adjust the inlet guide of the peeling machine.

[0037] In contrast, the present method proposes in particular a method for setting up the infeed guide of a peeling machine in which the operator of the peeling machine is additionally provided with quantitative information about the deviation between the theoretical center of the product to be peeled in relation to the peeling head, i.e. in relation to the center of the orbit of a cutting edge of a peeling tool on the peeling head, or about a deviation of the product to be peeled from its target guide position, in particular visually, and thus his control carried out by him during the ongoing operation of the peeling machine is supported by this information.

[0038] The aspects presented here can advantageously lead to an unexpectedly significant improvement in the control quality when setting up the inlet guide.

[0039] In particular, it can be achieved that defects in the blank material being produced can be almost completely avoided. Defects refer specifically to surface irregularities, for example, a surface section that was not reached by the machining process.

[0040] As a result of improved control quality, it can be advantageously achieved that the material allowance added during the forming process for the peeled material can be reduced compared to the level that can be reliably achieved later for the bright steel. Consequently, the volume to be machined by the peeling machine can be reduced, the peeling process accelerated, and material losses minimized, making the entire process chain for producing bright steel more efficient and economical.

[0041] Furthermore, it is conceivable that the required level of training of the machine operator, who is to carry out the procedure proposed here on a corresponding peeling machine, can be reduced, thereby making it easier to avoid any personnel bottlenecks or to reduce personnel costs.

[0042] In the method according to the invention, a force occurring between the inlet guide and the material to be peeled is measured for the control.

[0043] Specifically, the idea here is that the force or forces to be determined are determined using a force sensor which is at least indirectly in an operative connection with a guide roller of the peeling machine, in particular its inlet guide.

[0044] Furthermore, it is specifically intended that a relationship should exist between a measured force or several measured forces and a deviation between the theoretical center of the peeling material in relation to the peeling head, i.e., in relation to the center of the orbit of a cutting edge of a peeling tool on the peeling head, or via a deviation of the peeling material from its intended guide position, which can be used to deduce a corresponding deviation from a measured force or forces, or to keep this deviation as constant as possible by means of a control system.

[0045] The aspect presented here offers the advantage of achieving a simple measurement setup, which can be used to obtain quantitative information about such a deviation.

[0046] In particular, force sensors are especially robust, which also makes it advantageous to achieve a high availability of a measuring device.

[0047] According to a third aspect of the invention, despite possible inaccuracies of the supplied peeling material, the highest possible quality of the peeled peeling material can be achieved by a computer-aided method for setting up an infeed guide of a peeling machine, in which a peeling material is guided by means of the infeed guide in relation to a peeling head carrying peeling tools and the peeling machine has a data processing and evaluation unit which is set up to carry out a method according to the first two aspects in a computer-aided manner.

[0048] In this context, a "data processing and evaluation unit" is understood to be an electronic component or device designed for processing and evaluating data. In particular, a data processing and evaluation unit may include a processor configured for data processing. A data processing and evaluation unit typically aims to manage data in an organized manner, enabling the acquisition of information about the data and the modification of the data itself. Specifically, a data processing and evaluation unit may be configured to execute an automated control algorithm and transmit the calculated control values ​​to the corresponding actuators, allowing the peeling machine to be controlled autonomously by the data processing and evaluation unit.

[0049] Specifically, a computer-aided method for setting up the infeed guide of a peeling machine is proposed. In direct comparison to the first two aspects and the third aspect, the peeling machine then preferably requires a data processing and evaluation unit to execute the computer-aided method. This unit is designed to autonomously carry out the computer-aided setting procedure and to transmit calculated control values ​​to the corresponding actuators of the peeling machine.

[0050] The advantage of the aspect presented here is that a peeling machine equipped with the computer-aided setting procedure can be controlled autonomously or at least semi-autonomously, thereby reducing personnel costs for the operation of such a peeling machine.

[0051] It should be expressly noted that the subject of the third aspect can be advantageously combined with the first two aspects, either individually or cumulatively in any combination.

[0052] According to a fourth aspect, a peeling machine comprising an inlet area with an inlet guide, a peeling head carrying peeling tools and an outlet area, wherein the inlet guide carries at least two guide rollers by means of at least one roller carrier each, wherein at least one of the roller carriers can be adjusted via at least one guide roller actuator, can enable the highest possible quality of the peeled product despite possible inaccuracies of the supplied material, if the peeling machine includes a measuring device for determining a deviation of the product from its target guide position.

[0053] In the present context, the "inlet area" of a peeling machine is preferably that area of ​​a peeling machine in which the material to be peeled comes into contact with the peeling machine.

[0054] In this context, the "outlet area" of a peeling machine is preferably the area where the bright steel exits the peeling machine.

[0055] In this context, a "guide roller" refers specifically to a mechanical roller designed to guide the material being peeled. In particular, the material can roll over the guide roller and its direction of travel can be influenced.

[0056] The term "roller carrier" refers in particular to the part or component of a peeling machine which serves as a support for a guide roller and consequently connects the guide roller to the peeling machine.

[0057] In this context, a "guide roller actuator" is understood to mean, in particular, any actuator designed to vary the distance between the guide roller and the center of the orbit of a cutting edge of a peeling tool on the peeling head, preferably by adjusting the longitudinal extent of the guide roller actuator. The longitudinal extent of the guide roller actuator then serves as a control variable for the infeed guide of a peeling machine. By varying this control variable, the theoretical center of the material to be peeled, relative to the center of the orbit of a cutting edge of a peeling tool on the peeling head, can be varied.

[0058] In particular, when considering a control variable of the inlet guide, the longitudinal extent of a guide roller actuator should be taken into account.

[0059] In this context, a "measuring device" preferably refers to a device for measuring a physical quantity. In particular, a measuring device is understood to be a device by means of which the deviation of the material being peeled from its target position can be determined, at least indirectly. The measuring device can be directly configured to determine the longitudinal extension of the guide roller actuator. As a special feature, the measuring device can also be configured to transmit the target value for the longitudinal extension of the guide roller actuator to the guide roller actuator itself. It is also conceivable that the measuring device measures a force or forces that can be considered a corresponding measure, for example, of the deviation of the material being peeled from its target position or similar.Furthermore, the measuring device can be set up to output the deviation of the peeling material from its target guide position to a visualization, so that the deviation of the peeling material from its target guide position can be displayed by the visualization.

[0060] The previous state of the art involved a skilled worker controlling a peeling machine based on deviations immediately visible to him. These included defects in the surface finish of the bright steel being produced and an uneven distribution of the material to be machined. In other words, the skilled worker only had qualitative information about the position of the material to be peeled available for controlling the peeling machine.

[0061] In contrast, it is proposed here to provide the operator of the peeling machine with quantitative information about the deviation of the peeling material from its target position via the measuring device.

[0062] The advantage of the aspect presented here is that the operator of the peeling machine receives more precise information about the deviation of the product being peeled from its target position, so that manual control interventions can also be carried out with greater precision.

[0063] Preferably, the measuring device is interactively connected to the guide roller actuator. In this context, "interactive connection" is understood to mean, in particular, that the guide roller actuator and the measuring device are connected by means of a data line or other signal connection, wherein the measuring device is configured to transmit the setpoint for the longitudinal extension of the guide roller actuator to the guide roller actuator and / or to read the actual value for the longitudinal extension of the guide roller actuator from the guide roller actuator. Advantageously, this allows the peeling machine to be controlled directly by the measuring device or enables the establishment of a corresponding control loop.

[0064] In a particularly preferred embodiment, the measuring device is arranged on the roller carrier, which can be adjusted via the guide roller actuator, and / or on the guide roller supported by it. Advantageously, this enables direct measurement at a local point of application of the inlet guide on the respective peeling material. In particular, in combination with an interactive connection between the measuring device and the guide roller actuator, precise control at a single guide roller can be advantageously achieved. The corresponding control can thus be finely tuned.

[0065] In the peeling machine according to the invention, the measuring device comprises a force sensor. Accordingly, a "force sensor" is understood to be any sensor designed to determine the physical quantity of a force. A force sensor enables a simple and precise measurement of a physical quantity that can be considered proportional to the deviation of the product being peeled from the target guide position, particularly when the infeed guide includes a spring, since forces can be measured easily and precisely there.

[0066] Preferably, the inlet guide carries three, four, five, or seven guide rollers, each supported by the inlet guide via a roller carrier, wherein each roller carrier is adjustable via at least one guide roller actuator. This enables correspondingly more precise guidance. Optionally, the roller carriers can also carry more than one guide roller, for example, two, three, or four guide rollers, whereby in these cases, three, four, five, or seven roller carriers are particularly suitable. Instead of guide rollers, guide rails can also be provided, which can then be supported by corresponding carriers, preferably three, four, five, or seven carriers.

[0067] Preferably, each of the guide roller actuators is interactively connected to a measuring device, so that precise and good all-round measurement and also individual control of the guide rollers is possible.

[0068] If each measuring device is arranged on the roller carrier belonging to the corresponding guide roller actuator and / or on the guide roller supported by it, accurate measurement of each of the guide rollers can be ensured.

[0069] Preferably, the peeling machine is configured to carry out a method according to claim 1.

[0070] The advantages of a method or a computer-aided method for setting up an inlet guide of a peeling machine, in which a product to be peeled is guided by means of the inlet guide in relation to a peeling head carrying peeling tools, can be directly applied, as described above, to a peeling machine comprising an inlet area with an inlet guide, a peeling head carrying peeling tools and an outlet area, wherein the inlet guide carries at least two guide rollers by means of at least one roller carrier each, wherein at least one of the roller carriers can be adjusted via at least one guide roller actuator, and wherein the peeling machine includes a measuring device for determining a deviation of the product to be peeled from its target guide position.

[0071] Further advantages, objectives, and features of the present invention are explained with reference to the following description of exemplary embodiments, which are also illustrated in the accompanying drawing. The drawing shows: Figure 1 schematically shows a peeling machine in the area of ​​a peeling head and a feed device with a feed assembly and an infeed guide; Figure 2 shows the peeling machine from the preceding Figure 1 , in which both the feed apparatus and the infeed guide are separated from the peeling machine drive; Figure 3 schematically shows a view of the infeed guide with wedge clamping elements in the transport direction of a peeling material; and Figure 4 schematically shows a view of an alternative infeed guide with wedge clamping elements in the transport direction of a peeling material.

[0072] The in the Figure 1 and 2The peeling machine 1 shown has a feed device 3 in the area of ​​its peeling head 2 with its peeling tools 8.

[0073] In order to ultimately carry out a peeling process, the peeling head 2 and thus also the peeling tools 8 can rotate.

[0074] The in the Figure 1 and 2 The illustrated feed device 3 in turn has a feed apparatus 4 and an inlet guide 5.

[0075] The feed unit 4 and the infeed guide 5 are arranged to be displaceable on a crossbeam 6 of the peeling machine 1, the crossbeam 6 forming a linear guide 7 for the feed unit 4 and the infeed guide 5. Both the feed unit 4 and the infeed guide 5 can be moved along the linear guide 7 in both directions indicated by arrows 11 and 12. Thus, the feed unit 4 and the infeed guide 5 can be moved individually away from or towards a peeling machine drive 13 of the peeling machine 1. Furthermore, the feed unit 4 and the infeed guide 5 can be moved relative to each other. This means that the feed unit 4 can also be moved independently of the infeed guide 5 and vice versa on the crossbeam 6. It is understood that in alternative embodiments, a different arrangement of the feed unit 4 and the infeed guide 5 can be chosen.

[0076] In the Figure 1 In the illustrated operating state of the peeling machine 1, the feed unit 4 and the infeed guide 5 are connected to form a compact feed unit 3, and the feed unit 3 is furthermore connected to the peeling machine gearbox 13 of the peeling machine 1 via the infeed guide 5. To ensure that both the feed unit 4 and the infeed guide 5 can be reliably connected to the peeling machine gearbox 13, particularly in the operating state shown here, the feed unit 4 and the infeed guide 5 are secured by means of first upper wedge clamping elements 14 and 15 and by means of first lower wedge clamping elements 16 and 17 (see also Figure 3The inlet guide 5 and the peeling machine drive 13 are firmly but releasably clamped together by means of a second upper wedge clamping element (not explicitly shown here) and a second lower wedge clamping element (not explicitly shown here).

[0077] In this clamped state, a product 22 can be precisely guided by the feed device 4 via the inlet guide 5 to the peeling head 2 of the peeling machine 1 and thus to the rotating peeling tools. For this purpose, the product 22 is continuously guided by the feed device 3 in the transport direction 24 from an inlet area 23 through the peeling machine 1 to an outlet area 25.

[0078] The feed apparatus 4 is arranged according to Figure 2The feed unit 4 has been relocated from the inlet guide 5 in such a way that an assembly space 26 is created between the feed unit 4 and the inlet guide 5, which allows good accessibility at both the inlet guide end 27 of the feed unit 4 and the feed unit end 28 of the inlet guide 5. To create the assembly space 26, the feed unit 4 is spaced 29 away from the inlet guide 5.

[0079] Furthermore, the following applies to the arrangement according to Figure 2 The feed device 4 and the infeed guide 5 have been relocated so far from the peeling machine drive 13 of the peeling machine 1 that an additional assembly space 30 is provided between the infeed guide 5 and the peeling machine drive 13. Accordingly, the infeed guide 5 is located a distance 31 from the peeling machine drive 13.

[0080] It is understood that the inlet guide 5 and the feed device 4 do not necessarily have to be designed to be detachable and movable relative to each other in every embodiment. In particular, they can, for example, also be fixedly spaced apart or arranged in some other way, as long as a feed on the one hand and a guide on the other hand can be ensured.

[0081] In the present embodiments, the feed apparatus 4 has a torsionally rigid frame 32 in which, in addition to the infeed rollers 33 (numbered here only by way of example), a drive and adjustment mechanism 34 for the infeed rollers 33 is also arranged.

[0082] Furthermore, in these embodiments, the inlet guide 5 has a first locking bolt 35 and a second locking bolt 36 (see [reference]). Figures 3 and 4 ) on.

[0083] In this embodiment, the peeling machine drive 13 also has a first and a second locking bolt (not explicitly shown here).

[0084] The first locking bolt 35 of the inlet guide 5 is effective in the operating state (see Figure 1 The peeling machine 1 has a complementary locking sleeve 39, and the second locking bolt 36 interacts with a complementary locking sleeve 40 in the operating state. The locking bolts 35 and 36 ensure that the frame 32 of the feed unit 4 and a torsionally rigid box 41 (see Figures 3 and 4The inlet guide 5 moves the two parts towards each other. Furthermore, the torsionally rigid frame 32 and the torsionally rigid box 41 are additionally secured against rotation relative to each other by the locking bolts 35 and 36, in addition to the linear guide 7. The locking bolts 35 and 36 make the entire feed unit 3 significantly more robust and torsionally rigid. It is understood that in alternative embodiments, torsional rigidity can also be ensured or sufficiently guaranteed in other ways.

[0085] The same applies to the locking bolts of the peeling machine drive 13. These interact with corresponding locking sleeves (not explicitly shown here) provided on the infeed guide 5. The functional connection is described in detail here only as an example between the feed unit 4 and the infeed guide 5. Depending on the specific design, sufficient guidance and fixation of the assemblies described above can be achieved with just two locking bolts and corresponding complementary locking sleeves. It is understood that in further embodiments, more than two locking bolts and locking sleeves may be used.

[0086] In this embodiment, the inlet guide 5 additionally has locking bolts 35 and 36, which pre-fix the feed device 4 and the inlet guide 5 to each other independently of the wedge clamping elements 14, 15, 16 and 17.

[0087] In the lower section 45 of the torsionally rigid box 41 of the infeed guide 5, a first running shoe 10 and a second running shoe 46 are arranged. The infeed guide 5 is connected to the linear guide 7 of the peeling machine 1 via the two running shoes 10 and 46 in a translationally displaceable manner.

[0088] In this embodiment, three guide rollers 42 arranged in a star shape are provided in the torsionally rigid box 41 of the inlet guide 5. Each of these guide rollers 42 is advantageously supported by a roller carrier 37, which in turn can be individually controlled by means of a guide roller actuator 38, which in this embodiment comprises an actuator 43 and a corresponding actuator gearbox 44, so that the material 22 to be peeled is guided to the peeling head 2 (see Figure 1 ) or can be fed to the peeling tools 8 with extremely high precision.

[0089] In this case, the connection between the guide roller actuator 38, or in this embodiment the actuator motor gearbox 44, and the respective guide roller 42 is spring-loaded via a disc spring assembly 19, so that out-of-roundness or other local deviations in the peeling material 22 can be compensated for.

[0090] The disc spring assembly 19 rests on the roller carrier 37 on one side and on an adjusting foot 47 on the other, which in turn can be adjusted by the respective actuator motor gearbox 44 towards or away from the peeling material 22.

[0091] Using a measuring dowel 20, the in Figure 3In the illustrated embodiment, the relative position between the respective roller carrier 37 on the one hand and the adjusting foot 47 on the other hand is measured via a position sensor 21. Due to the spring constant of the disc spring assembly 19, this represents a direct measure of the force acting between the roller carrier 37 or the guide roller 42 and the adjusting foot 47, or between the actuator motor gearbox 44 and the infeed guide 5. Accordingly, this arrangement provides a force sensor 18 that can measure a force occurring between the infeed guide 5 and the material to be peeled 22, or, together with the other force sensors 18, the forces occurring between the infeed guide 5 and the material to be peeled 22.

[0092] The exemplary embodiment differs slightly from this and is built according to Figure 4, in which the force sensor 18 is implemented by a force transducer 49, which is arranged in the adjusting foot 47 and can directly measure and then output forces acting on the adjusting foot 47.

[0093] The force sensors 18 are therefore part of a measuring device 9 for determining a deviation of the peeling material from its target guide position, since such deviations result directly in a change in the force or forces.

[0094] The measurement results from the measuring device 9 are then used to control the actuators 43 accordingly. Depending on the specific implementation, the measurement results of a respective force sensor 18 can be used directly to control the actuator 43 that acts on the roller carrier 37, to which the respective force sensor 18 is directly operatively connected. In other implementations, it is also possible to use the measurement results of all force sensors 18 to determine the signals controlling the actuators 43 from their combination, whereby both possibilities can also be combined or, if necessary, further measurement results can be used additionally.

[0095] In the present embodiment, the measured forces are displayed in a visualization 48.

[0096] The degree to which the individual guide roller actuators 38 are controlled is achieved in a control loop comprising the force sensors 18. In this embodiment, the control is effected via pulse delivery, whereby the step size of the pulse adjustment can be selected via the visualization. It is understood that in differing embodiments, the step size can be omitted or a different type of control can be chosen. Reference symbol list:
