Description

TECHNICAL FIELD

[0001] The invention relates to a sensor unit which can display the operating process and / or operating parameters of a spinning preparation machine and / or the quality of the fiber material to be processed by the spinning preparation machine. PRIOR ART

[0002] In a fiber preparation system of a spinning mill, fiber material supplied in the form of fibers or fiber clusters is prepared by fiber preparation machines for use in a spinning machine. In the fiber preparation system, the fibers to be prepared for spinning are passed through a plurality of processing stages. In a first stage, the fibers are detached from fiber bales in the form of fiber clusters. For this purpose, so-called bale openers are usually used. These fiber clusters are output from the bale opener by means of pneumatic fiber cluster conveyors and are conveyed, for example, to a downstream clearer. In subsequent stages, the fiber preparation system also has a series of clearers through which the fibers or fiber clusters are passed. The sequence and design of the clearers are adapted to the fibers to be processed and serve to clean, mix and separate the fiber clusters into individual fibers and to align them. The individual clearers in the fiber preparation system can be arranged in different ways, depending, inter alia, on the raw material to be processed and the product to be obtained.

[0003] The fiber preparation machines used are, for example, coarse cleaners, fine cleaners, foreign fiber separators, mixers, bale openers and devices such as carders, carding machines or draw frames. Other types of machines, such as intermediate reservoirs, collectors or combers, can also be equipped with fiber preparation machines. A single fiber preparation machine is equipped with a storage container, reservoir, collection container or filling slot or mixing chamber depending on the design. For the purposes of this application, a storage of fiber material which consists of a fiber material accumulation instead of an actual container is also referred to as a reservoir. For example, a fiber bale at the beginning of the process is also considered a reservoir. In different methods, the fiber material prepared by the fiber preparation machines is mostly placed in the form of a sliver in so-called sliver cans. For the purposes of this application, these sliver cans are also reservoirs.

[0004] The fiber preparation machines with reservoirs or chambers for reserving or storing fiber material are used to assess the condition of the fiber material. In order to obtain a visual impression of the fiber material, the operating personnel can take samples from the reservoirs. In this case, samples of the fiber material are taken at regular intervals at the respective fiber preparation machines and the material is examined by appropriate laboratory equipment. The disadvantage of this approach is that the process is time-consuming and the time lag until the analysis results are available does not reflect the current state of the material. If the samples are not taken in exactly the same way, there is also the problem of a scatter in the results. The laboratory tests are very time-consuming and, as a result, only a few samples are taken at the time of sampling, which means that there is still a high level of uncertainty in the results. At the same time, this also means that the fiber preparation machines will be shut down when they do not need to be. SUMMARY

[0005] The problem addressed by the present application is to provide a device which allows a real-time observation of the fibre material to be processed and thereby lays the foundation for a potential evaluation of the fibre material which can be used to optimize the processing of the fibre material throughout the fibre preparation process.

DETAILED DESCRIPTION

[0036] The above and other objects, features, aspects and advantages of the present application will become more apparent from the following detailed description of the embodiments, when taken in conjunction with the accompanying drawings, which illustrate and, by way of example, not limitation, the principles of the present application.

[0037] - Figure 1 A schematic side view of a spinning preparation system 300 according to one embodiment is illustrated;

[0038] - Figure 2 A schematic side view of a drum 210 with a portable sensor unit 100 according to one embodiment is represented;

[0039] - Figure 3 A schematic plan view of a portable sensor unit 100 according to one embodiment of the present application is shown;

[0040] - Figure 4 A schematic bottom view of one embodiment of a portable sensor unit 100 is presented;

[0041] Figure 1 An example of a spinning preparation system 300 according to one embodiment is shown. The spinning preparation system 300 can comprise a spinning preparation machine 200 and a portable sensor unit 100 as shown in Figure 1

[0042] In Figure 1 ​In the diagram, the spinning preparation machine 200 is a carding machine. However, the spinning preparation machine 200 can also be a de-packing machine, a cleaning machine, a mixer, a fiber bundle mixer, or a drawing frame. According to an embodiment, the spinning preparation machine 200 may also include a retainer for placing the portable sensor unit 100 on or against the spinning preparation machine 200.

[0043] exist Figure 1 In this process, three portable sensor units 100 are placed on or against the spinning preparation machine 200: one in the filling trough, one in the carding roller, and one behind the sliver forming unit.

[0044] The portable sensor unit 100 shown has, as Figure 4 The first interface 170 shown, and the spinning preparation machine 200 having, for example Figure 1 The second interface 270 shown is used to power and / or communicate with the portable sensor unit 100, enabling the spinning preparation machine 200 to power and / or exchange data with the portable sensor unit 100. According to an embodiment, the first interface 170 may preferably be a socket and / or plug, and the second interface 270 may correspondingly be preferably a plug and / or socket.

[0045] To prevent the portable sensor unit 100 from shifting, moving, or migrating, the portable sensor unit 100 may include a fastening member 160, allowing the portable sensor unit to be attached to the spinning preparation machine 200. According to one embodiment, the fastening member 160 may be in the form of a clamping member 110. Preferably, the fastening member 160 may be a bracket (not shown) that clamps the portable sensor unit 100 onto the spinning preparation machine 200 while also being able to be gripped in an open state for transporting the spinning preparation machine 200.

[0046] Figure 3 A plan view of the portable sensor unit 100 is shown, and the portable sensor unit may include a clamping member 110, a sensor 120, an evaluation unit 130, a display 140, and a control unit 150. As previously described, the portable sensor unit 100 may be placed on or against the spinning preparation machine 200 to display the quality of the fiber material 990 to be processed by the spinning preparation machine 200. In practice, the sensor 120 is configured to record the operation process and / or operating parameters of the spinning preparation machine 200 and / or the quality of the fiber material 990 to be processed by the spinning preparation machine 200. The operation process and / or operating parameters may also be determined by the first interface 170 and the second interface 270.

[0047] Preferably, the sensor 120 can be a camera 120 which is configured to monitor the quality of the fibre material 990 to be processed by the spinning preparation machine 200 and / or to record the operating process and / or operating parameters of the spinning preparation machine 200.

[0048] The information collected by the sensor 120, such as the operating process, the operating parameters and / or the quality of the fibre material 990, can be transmitted to the evaluation unit 130 in order to evaluate the operating process and / or the operating parameters of the spinning preparation machine 200 and / or the recording of the quality of the fibre material to be processed. This evaluation is displayed by the display 140 and the portable sensor unit 100 can thus signal the status of the operating process, the operating parameters and / or the quality.

[0049] The display 140 can be a display in different forms. According to one embodiment, the display 140 can be a screen 140 which can display the operating process and / or the operating parameters of the spinning preparation machine 200 and / or the quality of the fibre material 990 to be processed by the spinning preparation machine 200.

[0050] According to another embodiment, the display 140 can be a plurality of lighting elements which can also indicate the operating process and / or the operating parameters of the spinning preparation machine 200 and / or the quality of the fibre material 990 to be processed by the spinning preparation machine 200. According to the predetermined operating process and / or operating parameters of the spinning preparation machine 200, the control unit 150 can light up the plurality of lighting elements according to a lighting scenario in order to display the operating process and / or the operating parameters and the quality. Of course, the various lighting elements can form a monochrome or multicolour display 140 and / or can be arranged according to a 2D geometry or a 3D geometry, so that the operating process and / or the operating parameters of the spinning preparation machine 200 can be easily identified.

[0051] In fact, after the spinning preparation machine 200 has been started, the portable sensor unit 100 indicates, for example, that the operating process is smooth and no errors have occurred. If the operating parameters of the spinning preparation machine 200, such as the speed, the throughput, etc. are also set correctly, this information can be forwarded to the evaluation unit 130 and the control unit 150 thus controls the display 140 to display the information. As Figure 2 is shown, in order to measure the carding gauge via the sensor 120, the portable sensor unit 100 is likely to be attached to the drum 210.

[0052] As Figure 1One of the most important aspects of the present application is, as shown, the monitoring of the quality of the fibre material 990 to be processed by the carding machine 200. Thanks to the sensor 120 or camera 120, the portable sensor unit 100 can check the fibre material 990 located in the filling slot 218 of the carding machine 200. The portable sensor unit 100 is arranged at the side of the filling slot 218, which faces the surface of the fibre material 990 located in the filling slot. Then, the fibre material 990 with a certain degree of contamination is discharged from the filling slot 218 and roughly cleaned in the licker-in 220 and from there transported to the cylinder 210. On the circumference of the cylinder 210, the fibre material 990 is further cleaned and the individual fibres are aligned.

[0053] Then, the fibre material 990 enters the slivering unit 240 via the doffer 230, where the fibres are made into slivers 999. Thus, the slivers 999 leave the carding machine 200 and are stored in a sliver can (not shown) in a storage device. The sliver can can be used as a reservoir for the fibre material 990 leaving the carding machine 200 in the form of slivers 990. The portable sensor unit can also be arranged above the sliver can 100 and facing the surface of the slivers 999 located in the sliver can. The portable sensor unit 100 can also face, for example, a sliver can that is full and removed from the storage device.

[0054] In the present embodiment, the portable sensor unit 100 is arranged above or after the slivering unit 240. The portable sensor unit 100 observes the degree of contamination of the slivers 999 made, i.e. the quality of the slivers 999. According to the evaluation unit 130, the evaluation information can be displayed on the screen 140 and / or the multi-colour illumination 140 can emit a green light as long as the degree of contamination of the fibres is within a specified range.

[0055] According to the evaluation unit 130, the display 140 can display a warning and / or the multi-colour illumination 140 can emit an orange light as soon as the degree of contamination of the fibres changes significantly and the display 140 emits an alarm if the degree of contamination of the fibres exceeds the specified range, prompting that measures must be taken. The alarm mainly helps to make decisions. If the display 140 of the portable sensor unit 100 attached to the filling slot 218 does not report any abnormalities, but the display 140 of the portable sensor unit 100 arranged above or after the slivering unit 240 signals an error, this difference, for example, indicates that the settings of the carding machine 200 are no longer optimal.

[0056] On the other hand, if both portable sensor units 100 report an error, this indicates that the quality of the fiber material 90 that has entered the filling tank 218 has deteriorated. Thanks to the clamping member 110, the portable sensor unit 100 can be transported and used on another spinning preparation machine 200, so that the course of operation and / or the operating parameters of the other spinning preparation machine 200 and / or the quality of the fiber material 990 to be processed by the other spinning preparation machine 200 can be recorded.
