Description

Technical Field

[0001] The present invention relates to a spinning preparation machine for processing fiber bundles, the spinning preparation machine comprising: a frame; a fiber bundle reservoir fixed on the frame, the fiber bundle reservoir being fluidly connected to a fiber bundle inlet via an inlet and fluidly connected to a fiber bundle outlet via an outlet; and a weighing device disposed below the fiber bundle reservoir for measuring the filling state of the fiber bundle reservoir by weight. Background Technology

[0002] A spinning preparation machine for processing fiber bundles is known from EP 3 587 631 A1, wherein the frame of the spinning preparation machine is supported on a base at at least four support points. At least one weighing unit is provided between the frame and the base for measuring the filling status of the storage section of the spinning preparation machine that can be filled with fiber bundles.

[0003] A fiber metering feed device for introducing fibers into concrete is known from US2004255429. The device has a frame for supporting the fiber output device. Multiple weighing units are installed between the frame and the transport housing of the fiber metering feed device. Summary of the Invention

[0004] The objective of this invention is to provide a spinning preparation machine that enables more accurate gravimetric measurement of fill status.

[0005] The task is solved by a spinning preparation machine of the aforementioned type in the following manner: the spinning preparation machine has a separation device with at least three support points for standing upright on a fixed base plate, wherein the frame and the separation device are structurally separated from each other, and wherein the fiber bundle entry part is provided on the separation device.

[0006] In the operation of the spinning preparation machine, the fiber bundle is pneumatically transported through the fiber bundle inlet. Vibration occurs in this process; however, due to the structural separation of the separating device from the frame, this vibration is not transmitted to the frame. Thus, the fiber bundle inlet is separated from the frame. The separating device serves as a support structure for the fiber bundle inlet and is supported on a fixed base or pedestal on which the spinning preparation machine is erected in the spinning mill. This structural separation thus prevents distortion of the measured values ​​of the filling condition by gravimetric measurement using weighing equipment and reduces vibration-related interference factors in gravimetric measurements of the filling condition.

[0007] For reliable measurement of fill condition, it is specified that the mass can be determined by weight measurement through a weighing unit. Measurement of the entire machine is provided based on the structure of the spinning preparation machine. However, in the possible configuration of the spinning preparation machine as a channel mixer, it is preferable to measure the entire machine by calculating the fill condition of each channel.

[0008] According to the first construction scheme, the frame and the base plate are supported separately on the separating device, wherein vibration damping elements are arranged between the frame and the separating device. These damping elements are constructed to compensate for vibration and / or lateral forces. In particular, the weighing equipment may have at least two weighing units, also known as weighing units, wherein at least a portion of the vibration damping elements are arranged between the weighing units and the separating device. In this way, the separating device can support the machine structure, which also includes the frame and fiber bundle storage, just as the base frame rests against the fixed base plate.

[0009] According to the second construction scheme, the weighing equipment can be erected on a fixed base plate. Therefore, not only the separation device but also the frame itself can be erected on the fixed base plate. Specifically, the weighing equipment can have at least two weighing units, with at least a portion of the vibration damping elements disposed between the weighing units and the fixed base plate. The separation device can externally surround the frame to protect it from external disturbances. Vibration damping elements, constructed to compensate for vibrations and / or lateral forces, can be installed between the fixed base plate and the weighing units of the weighing equipment.

[0010] However, it is also possible in principle that the vibration damping element is placed between the weighing unit and the frame.

[0011] The weighing unit can be installed on the support points of the spinning preparation machine, with the connecting line of these support points parallel to the longitudinal axis of the machine. However, in principle, one weighing unit can also be installed at each support point of the machine.

[0012] The fiber bundle reservoir can have multiple side-by-side filling channels, arranged one after another along a longitudinal axis. Adjacent filling channels can be spatially separated from each other in a known manner by perforated partition walls. Two weighing units can be installed in a channel mixer with, for example, six filling channels. Three weighing units can be installed in a channel mixer with, for example, ten filling channels, based on the greater machine length. These weighing units are sufficient to determine the filling state of the mixer due to the long-term symmetrical weight distribution across the net width of the frame. The distribution of filler material in the channels can be inferred from the different weight distributions among the weighing units and other machine information.

[0013] The separating device may have a support foot that rests on a fixed base plate when the spinning preparation machine is in an upright position, and may be, for example, height adjustable for leveling.

[0014] Furthermore, the separating device may have an intermediate frame or be designed such an intermediate frame, which may in particular have a rectangular basic shape. The intermediate frame may have a connected support structure that surrounds the machine structure and supports the frame and fiber bundle storage unit, and is supported against a fixed base plate. Support legs may be provided on the intermediate frame. The intermediate frame may have a rectangular basic shape, and in principle, it may also have built-in transverse struts and / or longitudinal struts.

[0015] For an alternative intermediate frame configuration, the separating device can have multiple intermediate beams spaced apart from each other. The machine structure can then be erected on these intermediate beams to support the machine structure and abut against a fixed base plate. For example, the intermediate beams can be spaced apart from each other along the longitudinal direction of the frame and can be oriented transversely, and especially perpendicularly, to the longitudinal direction. Support legs can be mounted on the intermediate beams. The intermediate beams can be supported by struts. In particular, the intermediate beams can be supported at their respective ends. As in an intermediate frame, a weighing unit can be mounted between the intermediate beams and the frame (e.g., on all supports of the spinning preparation machine on the intermediate beams).

[0016] In a further extended design, it can be specified that the intermediate beam is hinged and supported at the end of the first beam against a fixed base plate. For this purpose, for example, the support element supporting the corresponding end of the first beam can be hinged to provide a hinged connection, specifically oriented parallel to the longitudinal axis. The corresponding end of the second beam can be supported on a weighing unit, which can be positioned between the corresponding end of the second beam and the fixed base plate. In particular, the corresponding weighing unit stands directly on the base plate.

[0017] Furthermore, flexible hose elements are provided between the fiber bundle inlet and the inlet, and / or at the outlet of the fiber bundle outlet, respectively, for vibration damping. The fiber bundle inlet and / or fiber bundle outlet are preferably constructed as tubular or channel-shaped to guide the fiber airflow from the pneumatically transported fiber bundle. Thus, a flow conduction connection with vibration damping characteristics is provided in a simple manner by means of flexible hose elements, which connects the fiber bundle reservoir to the fiber bundle inlet on the inlet side and can be connected to the fiber bundle outlet on the outlet side. The hose elements can be made of, for example, flexible plastic, rubber, or the like. The flexible hose elements are therefore vibration damping and do not affect the measurements of the weighing equipment.

[0018] Other vibrating components can also be mounted on the separation device to enable more accurate gravimetric fill condition measurements or to prevent gravimetric fill condition measurements from being distorted by vibrations introduced into the frame. Therefore, to eliminate the influence of individual machine components on fill condition measurements, these components can be separated from the frame to avoid potentially incorrect measurements, incorrect weight values, and incorrect fill condition information.

[0019] In particular, the fiber bundle discharge section can be designed as a tube to connect the filling reservoir to a downstream spinning preparation machine, which is mounted or supported on the spinning preparation machine. Therefore, the suction device can be separated from the weighing component or frame of the spinning preparation machine. The connection between the suction device or fiber bundle discharge section and the frame can also be achieved using flexible elements or flexible hose elements.

[0020] Furthermore, a maintenance platform can be installed on the separating device to enable operation at the fiber bundle storage area. This maintenance platform can be a fixed platform mounted on the separating device. In this way, although vibrations generated when the operator of the spinning preparation machine enters the maintenance platform reach the separating device, these vibrations are not transmitted to the frame due to the structural separation.

[0021] Furthermore, an exhaust fan located upstream of the fiber bundle reservoir can be mounted on the separation device. This exhaust fan is used in a known manner to pneumatically transport the fiber airflow through the fiber bundle inlet to the fiber bundle reservoir. The exhaust fan can be directly fixed to the separation device. Similarly, the exhaust fan can be fixed to a maintenance platform, which in turn is supported on the separation device.

[0022] It can also be specified that at least one metering feed device with at least one rotatably driven roller is provided at the lower end of the fiber bundle reservoir for processing the fiber bundle. In another construction, the fiber bundle reservoir may have multiple spatially separated filling channels. Here, it can be specified that a separate dedicated metering feed device is provided below each filling channel. The metering feed device as a whole can also be referred to as the discharge device of the spinning preparation machine. Thus, the discharge device has the roller of the at least one metering feed device on the lower side of the filling channel so as to be able to empty the filling channel. Here, all filling channels can be emptied simultaneously. In a known manner, the discharge device may include an inlet roller and a downstream opening roller. Below the traction device, a suction device, for example, operating in conjunction with fresh air supply, can be connected to convey the mixed fiber bundle to the next processing machine, particularly another spinning preparation machine.

[0023] The at least one metering feed device can be mounted on the separating device. In this way, the vibration generated by the at least one roller is introduced into the separating device, and since the structural separation does not reach the frame, the measurement of the fill status is not disturbed by the operation of the at least one metering feed device. The at least one roller can be an opening roller or an inlet roller. Preferably, the at least one metering feed device has multiple rollers. For example, the metering feed device can have two separating rollers and an opening roller disposed below them. Other combinations are also possible. Alternatively, the at least one metering feed device can also be mounted on or supported on the frame.

[0024] Spinning preparation equipment can be, for example, a carding machine with a cover plate, a roller carding machine, or a fiber mixer with one or more filling channels. For instance, a spinning preparation machine can be a fiber mixer configured as a channel mixer, such as the Trützschler MX-U mixer, whose functional principle is fully described. A spinning preparation machine configured as a channel mixer can have multiple filling channels, arranged side-by-side or sequentially along the feed direction. Fiber bundles can be injected into the individual filling channels through feed channels extending above them. The transport of the fiber bundles can be pneumatic, for example, by means of an exhaust fan coupled to the feed channel. A locking mechanism, such as a valve or a rotary slider, can be provided in the feed channel, wherein the locking mechanism can be opened and closed by a controller. For this purpose, each locking mechanism can cooperate with at least one actuator, which can be coupled to the controller.

[0025] A separation device can be used to move / push aside the at least one metering feed device located below the fiber bundle reservoir to remove possible blockages and / or dense points. Specifically, a guide device can be provided at the separation device to guide the at least one metering feed device to move along the longitudinal direction of the frame. In this way, the metering feed device can be moved to engage from below with the fiber bundle reservoir or its associated filling passage.

[0026] In addition, additional components can be installed on the separating device to protect the spinning preparation machine and, more importantly, the weighing equipment from external influences. For example, a collision protection device can be installed on the separating device to provide protection against collisions with land transport vehicles (such as forklifts).

[0027] Therefore, the separation device can be used as a base for weighing machine parts to be separated (maintenance platforms, exhaust fans, suction devices, etc.). In this way, components that cause vibration are supported on the separation device instead of on the frame to be weighed, and the vibration of these components could lead to inaccurate measurements during gravimetric measurements of filling conditions.

[0049] exist Figure 1 The image shows a spinning preparation machine 1 for processing fiber bundles 2 according to a first embodiment. This spinning preparation machine is constructed as a tunnel mixer and can be integrated into the cleaning line of a spinning mill in a known manner.

[0050] To clarify the spatial orientation of the spinning preparation machine 1, Figure 1 The longitudinal direction X, transverse direction Y, and height direction Z are drawn in the diagram. They are defined in the sense of the Cartesian coordinate system assigned to the spinning preparation machine 1 and are indicated by corresponding arrows. Concepts such as "below," "under," "above," or "above" here indicate spatial descriptions with respect to the height direction Z. The spinning preparation machine 1 can be erected on a fixed base plate 3, which lies in a horizontal plane opened by the longitudinal direction X and the transverse direction Y.

[0051] The spinning preparation machine 1 has a fiber bundle reservoir 4, which is divided into multiple, exemplary six here, filling channels 5 arranged side-by-side or one after another along the feed direction A. The feed direction or transport direction of the fiber airflow is... Figure 1Arrow A is used to indicate this. The filling channels 5 are spatially separated from each other by perforated partition walls 33. The filling channels 5 are connected to a feed channel 6 extending above them, which has a bottom plate opening 7 for each filling channel 5 to fill it with fiber bundles 2. An inlet 8 is connected to a central fiber bundle inlet 9, which can be tubularly designed and connected to an upstream spinning preparation machine (not shown) at its input end. The fiber bundles 2 are pneumatically transported through the fiber bundle inlet 9 and into the feed channel 6 by means of an exhaust fan 10. A controllable locking mechanism 11 is provided in the feed channel 6 to allow for controlled individual filling of each filling channel 2. A circulating air valve 41 is provided in the feed channel 6 between the inlet 8 and the bottom plate opening 7 along the feeding direction A. This circulating air valve, in its open position, releases the flow conduction connection between the inlet 8 and the circulating air channel 40. In the open position, the recirculating air valve 41 pivots into the feed channel 6 and locks the feed channel downstream of the recirculating air valve 41. Figure 1 The diagram shows the recirculating air valve 41 in its closed position, in which the recirculating air valve 41 blocks the recirculating air passage 40 and releases the feed passage 6. The recirculating air valve 41 can be moved from the open position to the closed position by means of an adjuster, and vice versa. When material is required, the recirculating air valve 41 is in its closed position so that fiber bundles 2 can be supplied to the filling passage 5. If there is no material requirement, the recirculating air valve 41 is moved to its open position, in which delivery air, which subsequently does not transport any fiber bundles, is guided through the recirculating air passage 40 through the filling passage 5.

[0052] A discharge device 34 is provided at the lower end of the fiber bundle reservoir 4. This discharge device has a metering feed device 12 for each filling channel 5 so that the corresponding filling channel 5 can be emptied in a controlled manner. The corresponding metering feed device 12 has an inlet roller pair 35 including two inlet rollers 13, 14 and an opening roller 15 disposed below the inlet roller pair 35. Below the discharge device 34, a suction device, for example operating with a fresh air supply L, can also be connected so that the mixed fiber bundle can be transported to the next processing machine, in particular another spinning preparation machine (not shown). For this purpose, a mixing channel 16 can be connected below the metering feed device 12, which extends in the longitudinal direction X across the filling channel 5 so that the removed fiber bundle 2 can be pneumatically transported via an outlet 17 through a connected fiber bundle discharge section 18 to the downstream spinning preparation machine (not shown).

[0053] The spinning preparation machine 1 also has a frame 19, on which a fiber bundle reservoir 4 with a filling passage 5, a feeding passage 6 disposed thereon, and a discharge device 34, as well as a mixing passage 16, are fixed. Furthermore, a machine housing 20 can be fixed to the frame 19. A separating device 21 is provided below the frame 19, which serves as the base of a machine structure 22, which includes the frame 19 and the fiber bundle reservoir 4 with the filling passage 5, the feeding passage 6, and the machine housing 20. The frame 19 and, in another embodiment, the entire machine structure 22, are supported or erected on the separating device 21 at a distance from a fixed base plate 3. The separating device 21 can be designed, for example, as a connected intermediate frame 23, which exemplarily has four support points 24 for erection on a fixed base plate 3. It goes without saying that in the case of larger or heavier spinning preparation machines, additional support points 24 can be added, or in the case of smaller spinning preparation machines, three support points 24 essentially ensure safe and reliable support. At each support point 24, a particularly height-adjustable support foot 25 is provided to orient the separating device 21 relative to the base plate 3.

[0054] A weighing device 26 for measuring the filling state of the fiber bundle storage 4 by gravimetric method is disposed between the intermediate frame 23 and the frame 19. Specifically, the weighing device 26 has multiple weighing units 27, on which the weight of the machine structure 22 is supported. Figure 2 The possible construction schemes of the weighing unit 27 are shown in detail. A vibration damping element 28 is provided between the weighing unit 27 and the separation device 21 (exemplarily, the intermediate frame 23).

[0055] During the operation of the spinning preparation machine 1, each filling channel 5 is filled with fiber bundles 2, and the fiber bundles 2 are removed by the metering feed device 12, thereby continuously changing the filling state of the fiber bundle storage device 4 or the filling channel 5. The fiber bundle storage device 4 is weighed by measuring the gravity acting on the weighing unit 27.

[0056] To prevent the measurement results obtained by means of the weighing device 26 from being distorted by vibration, or to minimize the introduction of vibration-related interference factors for gravimetric measurement of the filling state, the fiber bundle inlet 9, located upstream of the fiber bundle reservoir 4, is not fixed to the machine structure 22, but rather to the separation device 20. A flexible hose element 29 is provided between the tubular fiber bundle inlet 9 and the inlet 8 for vibration damping, providing a flow conduction connection between the fiber bundle inlet 9 and the inlet 8 into the supply channel 6. Furthermore, the exhaust fan 10 is supported on the separation device 21 or fixed to a fixed platform 30.

[0057] Here, by way of example, a fiber bundle discharge section 18 is also provided downstream of the fiber bundle reservoir 4 on the separation device 21. For this purpose, a tube holder 32 is connected to the intermediate frame 23, and the fiber bundle discharge section 18 is fixed to the tube holder. Another flexible hose element 31 is provided between the fiber bundle discharge section 18 and the outlet 17 for vibration damping, and this hose element provides a flow conduction connection between the mixing channel 16 and the fiber bundle discharge section 18.

[0058] exist Figure 3 The diagram shows a spinning preparation machine 100 according to a second embodiment, which corresponds to the embodiment described above to the greatest extent possible, thus referencing the above description in terms of commonalities. The difference lies in the construction of the metering feed device 12, which is fixed to the separating device 21 instead of being fixed to the frame 19. In this manner, the rotatably driven rollers 13, 14, and 15 of the corresponding metering feed device 12 are supported on the separating device 21. Furthermore, the mixing channel 16 is fixed to the separating device 21.

[0059] In the embodiment of the spinning preparation machine 100 shown here, an optional guide device 101 is provided on the separating device 21, extending in the longitudinal direction X. Here, only by way of example, each pair of metering feed devices 12 arranged adjacent to each other is combined into a module 113. Module 113 is guided, for example, on a track so that the metering feed devices 12 can be moved in a guided manner along the longitudinal direction X. In this way, the metering feed devices 12 can be moved module by module so that they can be engaged from below to the fiber bundle reservoir 4 or to the filling passage released by moving the individual modules 113 and / or laterally to the rollers 13, 14, 15 or to the spaces between the modules 113. Vibration damping elements (not shown) may be provided between the module 113 and the separating device 21. The metering feed devices 12 may also be fixed in position, i.e., fixed to the separating device 21 or fixed to the intermediate frame 23 without the guide device 101.

[0060] exist Figure 4 The diagram shows a spinning preparation machine 200 according to a third embodiment, which corresponds to the embodiments described above to the greatest extent possible, and thus references the above description in terms of commonalities. The only difference is the provision of a fixed maintenance platform 201, which is erected on or fixed to the separating device 21. The maintenance platform 201 can be accessed in a known manner, for example, via a ladder 202, to perform maintenance work on the spinning preparation machine 200. The metering feed device 12 is as shown in... Figure 1 As shown in the figure, or as the metering feed device 12 is in Figure 3 As shown in the figure, it can be integrated into the spinning preparation machine 200 in a modular structure.
