    [001] The invention relates to a conveyor belt stripper system with modules for the conveyor belt return zone, the belt stripper system being supported, fixedly or removably, on a support system perpendicular to the direction of travel of the conveyor belt. conveyor belt and consisting of multiple stripping modules, kept on the support next to each other. The stripping modules each have a stripping strip, resting on the belt in order to perform the stripping and being elastically pressed against the conveyor belt. Corresponding belt stripper systems have long been known as a proven state of the art, EP 254 977 B1 being referred to as an example here.
    [002] The known belt stripper systems are used for the most varied conveyor belts and under the most diverse transport conditions. They also have to have good characteristics that are rapidly changing, and they can always work reliably, both outdoors, when the rain falls, away from the factories, as well as in the collection of raw materials, where long periods of downtime are required. Downtime should be kept as short as possible because, as a rule, high monitoring costs result from production downtime.
    [003] These requirements are solved through modular construction. Ordinary modules, as described, for example, in EP 254 977 B1 and in DE OS 36 20 960, feature: • a base, which is attached to the support system, • a blade support, on which is located a stripper blade is placed, • a stripper edge, placed on the stripper blade, • and a stripper body with • a chuck, where the blade support is rotatably installed and • a joint with a torsion spring connecting base and stripper body.
    [004] Long downtimes are also achieved when the pickling strips have wear-resistant carbide blades, only very slowly wearing out, resulting in a sharp blade like a knife. This knife-sharpened carbide blade leads to problems, with disruptions in operation and the performance of maintenance tasks.
    [005] After the disconnection of a conveyor belt installation, it is often observed that the conveyor belt recedes a little, as a result of the conveyor belt, stretched elastically during operation, to contract again when the installation stops. According to the installation, the inevitable return can reach several meters. With this, the carbide edge can be thrown against the belt, causing, due to the sharp carbide edge like a knife, damage to the belt. In maintenance tasks it is also necessary to avoid cutting the carbide edge during assembly and disassembly of the conveyor, which makes adjustment difficult.
    [006] If the belt fails or recedes during operation, the belt stripper is first elasticly repelled, moving away from the belt and then the belt stripper is again elasticly pushed into the belt, due to which this spring return action it has to be carried out very precisely. Here is the technical problem of shaping the stripper and the stripper so that, during joint wear, the initial installation in the stripper system remains practically unchanged and this is true for all operating cases. and cargo.
    [007] Later, after total wear of the carbide blades, the modules have to be replaced with new modules. If this maintenance date is exceeded, the blade holder wears out quickly, until at last only the blade holder arm touches the belt. This can, through a strong increase in surface pressure or the creation of sharp edges, lead to damage to the belt.
    [008] Safety regulations prohibit the execution of stripper assembly work inside and under conveyor belts without special safety measures. Thus, strippers must be able to be assembled from the outside and the necessary fine adjustments of the module must also be able to be made from outside the belt equipment.
    [009] The object of the invention is therefore to provide a device, simple and economical, solving the problems described above and being both quick and simple to assemble. The intention is thus to produce a stripper with the invention bringing, together with its simpler modular construction, a higher pickling power, very simple, therefore without technical personnel to assemble it, where the assembly of the stripper will be carried out only from the outside of the construction of the equipment and the replacement of the modules, due to the wear of the cleaning edges, will be done from the outside of the construction of the equipment. The stripper must operate without any maintenance until the carbide edges are completely worn. A belt return, as is often the case for a variety of reasons, should be possible without damaging the stripper or the belt. The stripper must have a device that makes it possible to measure the irregularities of the belt, after which the module can be adapted to the irregularities by means of a lifting device. The stripper must be kept largely free of accumulations of material, influencing the functioning of the device.
    [010] The invention achieves the objective by means of a stripper module mounted as one of a plurality, in a system of mobile support in height, presenting • a base fixed to the support system, • a blade support where it is located a stripping strip is placed and • where a stripping edge is located on the stripping strip and • where the stripping strip forms an obtuse angle in relation to the direction of travel of the brace, • a stripping body with a joint hinge with two joints, in which • a first joint, whose axis of rotation runs perpendicular to the direction of travel of the belt, with a torsion spring, which connects base and stripping body, pressing the spring to the stripping lamella against the belt, • a second articulation with a bushing where the blade holder is rotatably placed and whose axis runs along the direction of travel of the belt, thus directing the blade holder on the belt in such a way that the edge of the belt ecapante always rests horizontally on the belt, • a lifting device for the stripping module of the belt relative to the base, the first joint being equipped with a spring angle gauge and with a fixed stop to articulate.
    [011] By means of the fixed stop it is achieved that, after the assembly in the support system of all the stripping edges, the stripping modules of the belt are placed more or less in a horizontal plane. Through the introduction of the fixed stop the safety of the belt is increased, since the stripper module of the belt, even after the maintenance date has passed or after premature or complete wear, is only pressed until reaching that fixed stop and no more beyond against the brace.
    [012] The first joint with the fixed stop is, in a preferred embodiment of the invention, made with a rubber torsion spring, with an internal square to which a disk-shaped stop is attached, leaning it against a stop protrusion fixed to the hinge housing.
    [013] When the stripper is clamped against an irregular band, different degrees of tightness are verified in each of the modules. In an embodiment of the invention it is envisaged that the tightening differences will be evaluated by a measuring and sensing device integrated in each of the modules and then the tightening differences will be compensated by displacing the modules in height.
    [014] Due to the measuring and detection device, it is possible to establish the optimum close to the stripper without the need to work on the rails or under the conveyor belt. Thus, the necessary safety standards can be carried out on the spot, without the need to resort to expensive local scaffolding, common in the state of the art, constituting an advantage of the invention.
    [015] In an embodiment of the invention the measuring and sensing device is performed as an integrated measurement of the angle of the spring in combination with a ring, which is placed rotatably around the axis of rotation of the first joint and is placed concentrically on the first joint. This rim is dragged, with the stripper moving away from the belt, but it does not recede completely, but remains in the position of the greatest range of oscillation reached at that time. It also comprises an indicating device, with the help of which it is possible to know or read the speed achieved in relation to the starting point. In this way, the deviation of the rotating spring can be read.
    [016] In another embodiment of the invention, the measuring and detection device is performed as an integrated device for measuring the angle of the spring and a rotating plastic ring with an arrow-shaped tip indicating on a scale the deviation of the spring rotating.
    [017] In another embodiment of the invention, the rotating plastic ring is rotated against a foam disk or a rubber ring, on which or on which it rests with its lower dimension, so that the plastic ring, through the friction between the foam disc or the rubber rim and the plastic rim, it is held firmly in its hinged position, even when the grip on the module is removed again.
    [018] In another embodiment of the invention, a device for the electronic measurement of the rotation angle is provided on the side of the module where the stop is located. Such a device can, for example, be integrated into the cover. In this way, the position of the rotation angle can be determined, digitized and transformed into a signal, where the zero position and the final position are known. In another embodiment, the device for the electronic measurement of the angle of rotation is provided with a transmitter, which then sends a signal of the state of the modified angle of rotation to a transmitter located outside the modules.
    [019] In another embodiment of the invention a receiver is placed in the support system, receiving the signals emitted by the modules and evaluating them in an evaluation unit. This evaluation unit is preferably operated in such a way that it reports the remaining correct operating time of the most worn out module and provides three values: a first value for the perfect operating time, a second value for the pending service need and a third value in case the final stop has been reached and no stripping action is taken.
    [020] Advantageously, the evaluation unit is connected to an indicating device. Such an indicating device can, for example, be executed in such a way that at the end of the support system a green light is illuminated for the first value, a yellow signal for the second value and a green signal for the third value, so that the state of wear is known in advance as the warnings of a traffic light. Naturally, the same effect can be achieved with other indicators. It is also naturally possible to present digital signals as numerical values.
    [021] In another embodiment, it is foreseen to provide the evaluation unit with an issuer, which transfers the data or values received to a service station or control room further away. Evidently the indicators can be combined.
    [022] After the modules according to the invention have been assembled on the support system, the installation process proceeds with the following steps: 1. The paint stripper is placed against the belt by displacing the support system, until the first module to be in contact with the strap. All slave hands of the angle measuring device are then rotated to the fixed stop. 2. From this position, the stripper is pressed against the belt by a certain measure, by displacing the support system spindle. The highest position in the displacement of the support spindle is marked. 3. The support system, with the modules, is again removed and expanded in relation to the belt. 4. With the help of the position of the slave hands, it is then possible to check that all modules have the optimum tightness. 5. If the tightness of a module does not match the condition, the module is adjusted by displacing the base part of the module in height. 6. After the modules have been moved in height, the slave hands are returned to the zero position and the stripper is pressed again against the belt until the position of step 2 (marking) is reached again.
    [023] If necessary, repeat steps 3-6.
    [024] The advantages of the invention are as follows: • The angular position of the module's lampholder is determined in the making itself and not by means of measured tolerances or the material of the rubber elements or measurements of the edges of the rubber springs. • After mounting on the support system, all the stripping edges of the modules are arranged in the same horizontal plane. In this way, installation on the belt is facilitated and uniform installation of the modules is allowed. There is the possibility to measure and standardize the angle of tightening of the springs in all modules. • When moving to the belt, the module, at the first contact with the belt, is already tilted inward by a certain degree. This reduces the danger of gluing the module by tightening the stripper. Manual reinforcement of the pressure of the module when traveling to the belt is thus avoided. • The maximum extent of wear is limited by means of the fixed stop. This prevents the belt from being damaged due to heavily worn modules with delayed maintenance. • With the return of the belt, the stripper cannot cut or stick to the belt.
    [025] The invention will now be described in detail. The Figures, from Fig.1 to Fig.6 show: Fig.1 a module in front elevation, Fig.2 a module in side elevation, Fig.3 a module, in perspective, with the first joint open, Fig.4 an module with lift and rotating plastic rim, Fig.5 the lift of the strip remover module on a support system, in the belt, Fig.6 a cut, with the plastic rim necessary for the measurement.
    [026] Fig.1 shows, in front elevation, the stripping module of the belt, with a base 1, a stripping body 2, a blade holder 3 where a stripping strip 4 is placed at whose end the stripping edge is fixed 5. The stripping body 2 also comprises the bushing 6, where the blade support 3 is placed in a rotationally free manner. The bushing 6 is fixedly connected to the first joint 7 executed as a torsion spring joint and forms the second joint itself. The bushing 6, forming the second joint, and the housing of the first joint, constitute the stripping body 2. The first joint is connected to the base 1, which has a lifting device 8. The first joint has a spring angle meter 9 as well as a fixed stop 10 as a drag, dragging the rotating plastic ring 17 when tightening the module. The first hinge rotates about the axis of rotation 11.
    [027] Fig.2 shows, in side elevation, the stripping module as shown in Fig.1 and in addition the axis of rotation 12 of the second joint.
    [028] Fig.3 shows, in perspective, the stripping module as shown in Fig.1 and Fig.2, where the side opposite the first joint 7 of Fig.2 is shown open. Here you can see the stop protrusion 13, fixedly attached to the housing of the first joint. The thrust bearing consists of the stop disc 14 connected to the inner square 15. The inner square 15 is therefore fixed and does not rotate together with the stripping body 2. In the first joint, the torsion spring rubber 16 can be seen in passing , carried out according to the state of the art, as described, for example, in DE OS 36 20 960. During the wear of the stripping lamella 4, the blade support 3 moves more and more towards the belt and would end up damaging that if this were not prevented by the fixed stop, constituted here by the stop projection 13 and the stop disk 14.
    [029] Fig.4 shows a perspective view of the stripping module according to Fig.3, but on the opposite side. Here you can see the spring angle gauge 9 as well as the fixed stop 10. The plastic ring 17 with the arrow-shaped tip 18 shows the tightening of the rotating spring on scale 19, after the tightening has relaxed during assembly. This tightening should not be confused with the pressure force exerted by the stripper during the strip stripping operation. The pressure force changes with increasing wear, as the torsion spring rubber 16 yields slightly due to the change in the angle and the pressure force decreases accordingly. The clamping force indicator is used for assembly. During operation, the expansion of the stripping body 2 over the stripping stripping obstacles, triggers a deflection of the torsion spring rubber 16. After that, the arrowhead 18 no longer indicates the current tightening, but the maximum deflection and with that the maximum pressure force present during the movement. It is also to be considered that, for the tightening of the torsion spring rubber, there is still a tightening resulting from the upward displacement of the support system. The pressure force is produced by the sum of the clamping force and the retightening, less the reduction of the tightening following the yield of the torsion spring 16 during wear.
    [030] When the support system, carrying each of the strip stripping modules, after assembly, is again approached from the strap, from below, the strip stripping modules rise until they reach the strap, where they rest and they rub, by means of an elevation in height in the opposite direction to the displacement of the belt. The tightening is established at the factory by means of the stop protrusion 13 and the choice of the stop disk 14, where the geometry of the cavity in relation to the position of the inner square can be varied.
    [031] The stop disk 14 has two functions here: on the one hand it limits the deflection of the stripping body 2 in the direction of the belt, in order to prevent damage to the belt following the wear of the stripping lamellae 4 and on the other hand it is means of the geometry of the stop disk 14 which is tightly established. In this way, the fixed stop is made by means of a stop disk 14 and a stop protrusion 13, however there are also other possible means to reach the fixed stop according to the invention, without departing from the general idea of the invention. This fixed stop must not be confused with the fixed stop 10 of the spring angle gauge 9, which is located on the opposite side of the first articulation 7.
    [032] An example is shown in Fig.5 of how differences in elevation of the belt surface are measured and after that the strip stripping modules of the belt are moved in height, in order to subsequently achieve the settlement of all stripping edges with the same predetermined pressure. The top view shows a stripper with five modules on a support system 21, having already been tightened and relaxed again. In the magnifying glass, you can see which grip mark the arrowhead of the plastic rim indicates. Only for each of the outer modules does the arrowhead point to the fourth and longest marking, meaning that these modules were completely tightened. The middle module shows mark two and the remaining two mark the third mark. These modules are therefore not completely tightened and need to be repositioned in height, each of them due to the difference of the indicators in relation to the outer module. The arrow on the intermediate module points to marking two and two ticks (4-2 = 2) must be moved upwards. In the other two modules, the hands are on the third tick and each need only be moved upwards by a tick (4-3 = 1). In the second view, the stripper is shown with the modules installed at the top. It can be clearly seen that the belt, in the stripper's work area, is concave curved and the modules are now adapted to this curvature. The stripper can then be put into operation and all modules, now with their axes aligned, have the same tightening as expected. If necessary, straightness can be simply controlled by repeating the described procedure.
    [033] In Fig.6 it is represented as the plastic ring 17, necessary for the measurement, it is placed in the fixed part of the stripper module of the belt. It is pressed against a rubber ring 23 of a slightly smaller diameter so that, as mentioned above, it can be rotated by hand with moderate effort.
    [034] The activation of the strip stripping modules will be described in detail below. For this purpose, the strip stripping modules are fastened at the factory against an internal stop and thus delivered to the place of use. The stripping modules of the strap can also be mounted on a support system at the factory, but it is also possible to mount them at the point of use. After the new support system has been installed, the support system spindles are raised in two working steps. In the first working step, the support system is moved upwards, until the ends of the stripping edges of a stripping module of the belt touch the belt. If the belt is not level, each of the stripping modules of the belt can be individually oriented and adjusted, so that each one of them touches the belt in a horizontal straight line through its stripping edge, as previously described.
    [035] Then, in the second working step, the stripper is again moved in height by a measure referred to in the installation and operating instructions, for example 20 mm. Then the travel spindles are fixed and the paint stripper is ready for operation. From that point on, the stripper should not and does not need to be moved further until the stripper edges are completely worn.
    [036] This factory tightening is chosen so great that the vertical pressure first produced by the spindle acting in the direction of the belt is sufficient for the proper cleaning of the belt, therefore even when the second upward spindle tightening path is used and due to the wear. With the second spindle elevation at around the measurement referred to in the operating instructions, for example 20 mm, the tension of the torsion spring and with it the vertical pressure acting in the direction of the belt, correspondingly rise. This additional applied spring tension decreases slowly with the gradual wear of the sipes. If the 20 mm is exhausted, the module rests on the internal stop and the sipes stop putting pressure on the belt.
    [037] An indispensable characteristic of the stripper is that the stripper modules of the belt have to be constructed in such a way that they always work properly, even with the return movement of the belt. This contributes to the relationship between the horizontal spacing of the axis 11 and the stripping edge 5 and the vertical distance between the axis 11 and the strip relative to the stripping edge 5. This relationship must always be greater than the wear value between the strip and the stripping edge material. Since this ratio only increases with the second spindle rise, the minimum ratio can be established at the factory. For typical use cases it reaches at least 0.7.
    [038] In the course of operation, each of the stripping modules on the belt reaches its wear limit at different times. Despite the displacement in height of the base part up to 20 mm, there is no danger to the strap, because the fixed stop, built as a stop protrusion 13 and a stop disc 14 safely prevent this, regardless of the height travel of the base part. base.
