Description

[0001] Portable sensor unit and spinning preparation machine

[0002] Technical area

[0003] The invention relates to a sensor unit that can display the operating process and / or the operating parameters of a spinning preparation machine and / or the quality of the fiber material to be processed by the spinning preparation machine.

[0004] State of the art

[0005] In a fiber preparation plant in a spinning mill, delivered fiber material is prepared in the form of fibers or fiber flakes for use in a spinning machine using fiber preparation machines. In a fiber preparation plant, the fibers to be prepared for spinning undergo several processing stages. In a first stage, the fibers are separated from fiber bales in the form of fiber flakes. So-called bale openers are usually used for this purpose. These fiber flakes are removed from the bale opener via a pneumatic flake conveyor and transported, for example, to a downstream cleaning machine. In the subsequent stages, the fiber preparation plant has a sequence of cleaning machines through which the fibers or fiber flakes pass.The cleaning machines are tailored to the fibers being processed in terms of their sequence and design. They are used to clean, mix, and separate the fiber flakes into individual fibers, as well as to parallelize them. The arrangement of the individual cleaning machines in a fiber preparation plant can vary, depending, among other things, on the raw material being processed and the desired product.

[0006] Examples of fiber preparation machines used include coarse cleaners, fine cleaners, foreign matter separators, mixers, openers, as well as cards, cards, or draw frames. Other types of machines such as intermediate storage units, collectors, or combers are also classified as fiber preparation machines. Depending on the design of the individual fiber preparation machine, these are equipped with a storage container, a buffer, a collecting container, or even a filling chute or mixing chamber. For the purposes of this application, a fiber storage unit is also referred to as such if it consists of an accumulation of fiber material without representing an actual container. For example, the fiber bales at the beginning of the process are also considered storage units. In various processes, the fiber material that has been fully processed by a fiber preparation machine is deposited in so-called cans, usually in the form of fiber slivers.These jugs also constitute a storage device within the meaning of this application.

[0007] Fiber preparation machines with a storage unit or chamber for storing or preserving fiber material are used to assess the condition of the fiber material. To create a visual impression of the fiber material, the operating personnel can take a sample from the storage unit. A sample of the fiber material is periodically taken from each fiber preparation machine and examined on appropriate laboratory machines. The disadvantages of this procedure are, on the one hand, time-consuming and, on the other hand, the analysis results are delayed and do not reflect the current status. If the samples are not taken exactly the same, the results are further variance. Laboratory tests are very time-consuming and therefore only a small number of samples are taken, which continues to result in a high degree of uncertainty.At the same time, this means that the fiber preparation machine is shut down at a time when it is no longer needed.

[0008] Summary of the invention

[0009] The object of the invention is therefore to create a device that enables real-time observation of the fiber material to be processed, thereby creating the basis for a possible evaluation of the fiber material that can be used to optimize the fiber processing processes throughout the entire fiber preparation process. This object is achieved by a device having the features of the independent claim.

[0037] Description of the embodiments

[0038] The above and other objects, features, aspects and advantages of the invention will become apparent from the following detailed description of the embodiments, which are given by way of illustration and not by way of limitation with reference to the accompanying drawings, in which

[0039] - Figure 1 illustrates a schematic side view of a spinning preparation system 300 according to an embodiment;

[0040] - Figure 2 shows a schematic side view of a drum 210 with a portable sensor unit 100 according to an embodiment;

[0041] - Figure 3 shows a schematic plan view of a portable sensor unit 100 according to an embodiment of the invention;

[0042] - Figure 4 presents a schematic bottom view of an embodiment of the portable sensor unit 100; Figure 1 shows an example of a spinning preparation system 300 according to an embodiment. This spinning preparation system 300 may include a spinning preparation machine 200 and a portable sensor unit 100, as shown in Figure 1.

[0043] In Figure 1, the spinning preparation machine 200 shown is a carding machine. However, the spinning preparation machine 200 can be a bale opener, a cleaner, a mixer, a tuft mixer, or a draw frame. Depending on the design, the spinning preparation machine 200 can also include a holder for placing the portable sensor unit 100 on or at the spinning preparation machine 200.

[0044] In Figure 1, three portable sensor units 100 are placed on the spinning preparation machine 200 or at the spinning preparation machine 200: one at the filling chute, one at the carding drum, and one after the sliver-forming unit.

[0045] The illustrated portable sensor unit 100 has a first interface 170, as in Figure 4, for example, and the spinning preparation machine 200 has a second interface 270, as in Figure 1, for example, which serves to supply power to the portable sensor unit 100 and / or to communicate with the portable sensor unit 100, so that the spinning preparation machine 200 can supply power to the portable sensor unit 100 and / or exchange data with the portable sensor unit 100. Depending on the embodiment, the first interface 170 can preferably be a socket and / or a plug, and the second interface 270 can preferably be a plug and / or a socket, respectively.

[0046] To prevent displacement, shifting, or relocation of the portable sensor unit 100, the portable sensor unit 100 may include a fastening member 160 so that it can be attached to a spinning preparation machine 200. According to one embodiment, the fastening member 160 may take the form of the gripping member 110; preferably, the fastening member 160 may be a clamp (not shown) that can clamp the portable sensor unit 100 to a spinning preparation machine 200 and, in the open state, can be gripped to transport the spinning preparation machine 200.

[0047] Figure 3 shows a top view of the portable sensor unit 100, which may include a gripper 110, a sensor 120, an evaluation unit 130, a display 140, and a control unit 150. As previously mentioned, the portable sensor unit 100 may be placed on or at a spinning preparation machine 200 to display the quality of the fiber material 990 to be processed by the spinning preparation machine 200. In fact, the sensor 120 is configured to detect the operating process and / or the 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 operating process and / or the operating parameters may also be determined via the first interface 170 and the second interface 270.

[0048] Preferably, the sensor 120 may be a camera 120 configured to observe the quality of the fiber material 990 to be processed by the spinning preparation machine 200 and / or to record the operating process and / or the operating parameter of the spinning preparation machine 200.

[0049] The information collected by sensor 120, such as the operating process, operating parameters, and / or quality of the fiber material 990, can be forwarded to evaluation unit 130 to evaluate the detection of the operating process and / or the operating parameter of spinning preparation machine 200 and / or the quality of the fiber material to be processed. This evaluation is displayed by display 140, and thus portable sensor unit 100 can signal the status of the operating process, the operating parameter, and / or the quality.

[0050] The display 140 can take various forms. According to one embodiment, the display 140 can be a screen 140 that can display the operating process and / or the 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.

[0051] According to another embodiment, the display 140 can be a plurality of light-emitting elements that can also display the operating 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. Depending on a predetermined operating process and / or operating parameter of the spinning preparation machine 200, the control unit 150 can illuminate the plurality of light-emitting elements according to a lighting scenario to indicate the operating process and / or operating parameters as well as the quality. Of course, the plurality of light-emitting elements can form a monochrome or polychrome display 140 and / or be arranged according to a 2D geometric shape or a 3D geometric shape, thus allowing the operating process and / or operating parameters of the spinning preparation machine 200 to be easily recognized.

[0052] Indeed, after the spinning preparation machine 200 has started up, the portable sensor unit 100 can indicate that the operating process, for example, went smoothly and no errors occurred. If the operating parameters of the spinning preparation machine 200, such as speed, production, etc., are also correctly set, this information can be forwarded to the evaluation unit 130, and the control unit 150 will then control the display 140 to show the information. It is also entirely possible for the portable sensor unit 100 to be attached to a drum 210 via the sensor 120 to measure the carding gap, as shown in Fig. 2.

[0053] One of the most important aspects of the invention is the observation of the quality of the fiber material 990 to be processed by the spinning preparation machine 200, as shown in Figure 1. Thanks to the sensor 120 or the camera 120, the portable sensor unit 100 can inspect the fiber material 990 located in the filling chute 218 of the card 200. The portable sensor unit 100 is arranged to the side of the filling chute 218 and is directed at the surface of the fiber material 990 located in the filling chute. The fiber material 990, with a certain degree of contamination, is then discharged from the filling chute 218 and roughly cleaned in a licker-in 220. From the licker-in 220, it is transferred to the drum 210. At the circumference of the drum 210, the fiber material 990 is further cleaned, and the individual fibers are parallelized.

[0054] The fiber material 990 then passes via a doffer 230 into a sliver forming unit 240, by which the fibers are formed into a fiber sliver 999. The fiber sliver 999 then leaves the card 200 and is deposited in a depositing device in a can (not shown). The can can be used as a storage device for the fiber material 990 leaving the card 200 in the form of a fiber sliver 990. A portable sensor unit 100 can also be arranged above the can and is directed at the surface of the fiber sliver 999 located in the can. It is also possible to direct a portable sensor unit 100, for example, at cans that have already been filled and removed from the depositing device.

[0055] In this embodiment, a portable sensor unit 100 is located above the ribbon forming unit 240 or after the ribbon forming unit 240. This portable sensor unit 100 monitors the degree of contamination of the formed fiber ribbon 999, ie, the quality of the fiber ribbon 999. As long as the degree of contamination of the fibers is within a predetermined range, according to the evaluation unit 130, the information can be shown on a screen 140 and / or the polychrome lighting 140 can illuminate green.

[0056] As soon as the degree of fiber contamination changes significantly, according to the evaluation unit 130, the display 140 can show a warning and / or the polychrome lighting 140 can glow orange. If the degree of fiber contamination is outside the specified range, the display 140 alerts that measures must be taken. This alarm primarily helps in making a decision. If the display 140 of the portable sensor unit 100 attached to the filling chute 218 does not indeed report any anomalies, but the display 140 of the portable sensor unit 100 located above the sliver formation unit 240 or downstream of the sliver formation unit 240 signals an error, this discrepancy indicates that the settings of the card 200, for example, are no longer optimal.

[0057] On the other hand, if the two portable sensor units 100 report an error, this indicates that the quality of the fiber material 90 entering the filling chute 218 has deteriorated. Thanks to the gripper 110, the portable sensor unit 100 can be transported and deployed on another spinning preparation machine 200, so that the operating process 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 other spinning preparation machines 200 can be recorded.
