[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, the following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.
[0031] In the description of the utility model, it needs to be explained that the orientation or position relation indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer" and the like is the orientation or position relation based on the orientation or position relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.
[0032] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0033] As shown in Figs. 1-2 The carbon fiber yarn collecting and knot catching device of the utility model includes detection mechanism 3, control mechanism 4 and alarm mechanism 5, the detection mechanism 3 is arranged on one side of the tows 1 and is used for detecting the tow joint 2, the alarm mechanism 5 reminds the staff when the detection mechanism 3 detects the tow joint 2, and the control mechanism 4 is electrically connected with the detection mechanism 3 and the alarm mechanism 5 respectively.
[0034] In the embodiment, when the tow joint 2 exists, the detection mechanism 3 can detect the corresponding tow joint 2, the detection mechanism 3 sends the detection result to the control mechanism 4, and the control mechanism 4 controls the alarm mechanism 5 to work to remind the staff. After the on-site staff finds that the sound and light alarm lamp alarms, the on-site staff immediately inspects the tows 1, confirms the joint position and tracks the tow joint 2, performs the cutting roller and other related operations at the corresponding yarn collecting machine table, avoids the tow joint 2 from entering the finished product yarn cylinder, and affects the quality of the finished product.
[0035] In the embodiment, the product quality of the carbon fiber finished product can be improved, the tow joint 2 is avoided from being collected into the yarn cylinder due to the negligence of the staff, and the quality of the carbon fiber finished product yarn cylinder is affected. In addition, the staff does not need to frequently observe whether the tow joint 2 passes, and can concentrate more attention on the control of other finished product appearance indexes.
[0036] Specifically, the detection mechanism 3 comprises a set of pairs of photoelectric sensors, and a distance exists between two pairs of photoelectric sensors for the passage of the filament bundle 1. One of the two pairs of photoelectric sensors is a transmitting end of the pair of photoelectric sensors, and the other is a receiving end of the pair of photoelectric sensors. The transmitting end of the pair of photoelectric sensors emits light, and the receiving end of the pair of photoelectric sensors receives the light.
[0037] When the normal filament bundle 1 passes, the light intensity received by the receiving end of the pair of photoelectric sensors remains unchanged, and when the filament joint 2 passes, the light intensity received by the receiving end of the pair of photoelectric sensors changes, and the receiving end of the pair of photoelectric sensors transmits a signal.
[0038] In the embodiment, the distance between the transmitting end of the pair of photoelectric sensors and the receiving end of the pair of photoelectric sensors is adjustable. According to actual conditions, multiple parallel filament bundles 1 can pass between the transmitting end of the pair of photoelectric sensors and the receiving end of the pair of photoelectric sensors at the same time, so as to improve the efficiency of collecting the filament bundle 1.
[0039] In the embodiment, in order to improve the detection precision and accuracy of the filament joint 2, the pair of light beams formed between the two pairs of photoelectric sensors is close to the surface of the filament bundle 1 and parallel to the surface of the filament bundle 1.
[0040] Further, the two pairs of photoelectric sensors are arranged close to the flat section of the filament bundle 1. Since the pair of photoelectric sensors detects the change in light intensity to realize the detection of the filament joint 2, when the pair of photoelectric sensors is installed on the irregular section of the filament bundle 1, the irregular shape of the filament bundle 1 may interfere with the detection of the pair of photoelectric sensors, thereby causing a false judgment.
[0041] In the embodiment, the pair of photoelectric sensors can be a pair of ultraviolet photoelectric sensors or a pair of infrared photoelectric sensors. In the embodiment, no specific limitation is made, and only the detection requirement needs to be met.
[0042] In the embodiment, the control mechanism 4 comprises a control box 41, and the detection mechanism 3 and the alarm mechanism 5 are electrically connected with the control box 41. When the filament joint 2 passes, the receiving end of the pair of photoelectric sensors senses the change in light intensity, the receiving end of the pair of photoelectric sensors sends a signal to the control box 41, and the control box 41 receives the signal and further controls the alarm mechanism 5 to work, so as to remind the staff.
[0043] In the embodiment, the control box 41 can be a PLC control box 41. A control panel or a touch panel can be installed on the control box 41 to facilitate operation.
[0044] In this embodiment, the control box 41 is provided with a reset switch 42 for resetting the alarm mechanism 5. Specifically, when the yarn joint 2 passes, the control box 41 controls the alarm mechanism 5 to work. After the staff finds the alarm signal, the yarn 1 is immediately checked to determine the position of the yarn joint 2. At the same time, the reset switch 42 is pressed to restore the detection function and avoid the failure to trigger the alarm in time when the joint appears again.
[0045] In this embodiment, the alarm mechanism 5 includes an alarm component for issuing an alarm signal when the detection mechanism 3 detects the yarn joint 2. Specifically, the alarm component can be an alarm lamp, an alarm or an audio-visual integrated alarm device (audio-visual alarm lamp). When the yarn joint 2 passes, the control box 41 can control the alarm component to work to remind the staff.
[0046] In this embodiment, the detection mechanism 3, the control mechanism 4 and the alarm mechanism 5 adopt interlocking control, which is simple to install and operate, has high flexibility and high accuracy.
[0047] Specifically, the control box 41 is provided with a relay 7, and the circuit includes a pair of photoelectric sensor contacts 6, a first relay normally open auxiliary contact 8 and a second relay normally open auxiliary contact 9. The pair of photoelectric sensor contacts 6 are normally open contacts, which are closed when the yarn joint 2 passes. The relay 7 and the alarm mechanism 5 are located on two different branches, the first relay normally open auxiliary contact 8 and the relay 7 are located on the same branch, the second relay normally open auxiliary contact 9 and the alarm mechanism 5 are located on the same branch, the first relay normally open auxiliary contact 8 and the pair of photoelectric sensor contacts 6 are connected in parallel, and the reset switch 42 is arranged on the main circuit.
[0048] When the yarn joint 2 passes through the pair of photoelectric sensor contacts 6, the pair of photoelectric sensor contacts 6 are closed, the relay 7 is powered, the first relay normally open auxiliary contact 8 is closed, and the travel self-locking circuit is formed; at the same time, the second relay normally open auxiliary contact 9 is closed, the alarm mechanism 5 is powered to issue a signal to prompt the on-site staff. After confirmation by the on-site staff, the reset switch 42 is pressed, the relay 7 is de-energized, the self-locking circuit is disabled, the yarn joint 2 detection alarm function can be restored, and the purpose of continuous automatic detection of the yarn joint 2 is achieved.
[0049] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form, although the present application has been disclosed as above with preferred embodiments, however, it is not intended to limit the present application, any person skilled in the art without departing from the technical scheme of the present application can make some changes or modifications to the above-mentioned technical content for equivalent embodiments, the implementation schemes in the above-mentioned embodiments can be further combined or replaced, as long as it does not deviate from the technical scheme of the present application, any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical essence of the present application still belongs to the scope of the present application.
