Technical Field

[0001] This utility model relates to the field of sewing technology, and in particular to a device for guiding the sequential retrieval of error-prone parts at a sewing station. Background Technology

[0002] In sewing operations within the light industrial sewing technology field, multiple parts are often processed at the same workstation. Some of these parts are similar in appearance, differing only slightly in length, eyelet position, and other aspects. Currently, the differentiation and handling of these error-prone parts primarily rely on the operator's skill level for manual error prevention.

[0003] Because the differences between parts are small, manual identification is susceptible to factors such as fatigue and lack of concentration, leading to frequent errors in part usage. Such errors can not only cause product rework but, in severe cases, result in part scrapping, increasing production costs and impacting production efficiency. Currently, there is a lack of effective solutions to this problem in existing technologies.

[0004] To address this, a device for sequentially retrieving error-prone parts at sewing stations is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a sequential part-picking guide device for error-prone parts in sewing stations, thereby solving the problem of errors caused by reliance on manual identification in the prior art.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include: A sequential part retrieval guide device for error-prone parts in a sewing station includes a base and a controller. Several partitions are mounted on the base in an adjustable position, and a storage area for storing sewing parts is formed between two adjacent partitions. Each storage area has a retrieval port equipped with a monitoring component and a prompting component. An alarm component is provided at the bottom of the base. The monitoring component, the prompting component, and the alarm component are all electrically connected to the controller.

[0007] According to the present invention, a part-taking guide device for error-prone parts in a sewing station is provided, wherein the top of the base is provided with a plurality of slots at equal intervals, and the bottom of the partition plate is integrally formed with an insert block, the insert block being inserted into the slot.

[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figures 1 to 3 As shown, an embodiment of this utility model provides a sequential part retrieval guide device for error-prone parts in a sewing station, including a base 1 and a controller. Several partition plates 2 are installed on the base 1 in an adjustable position. A storage area for storing sewing parts is formed between two adjacent partition plates 2. A monitoring component 3 and a prompting component 4 are provided at the retrieval port of each storage area. An alarm component 5 is provided at the bottom of the base 1. The monitoring component 3, the prompting component 4 and the alarm component 5 are all electrically connected to the controller.

[0019] In this embodiment, the controller can be an STM32 series microcontroller or a small PLC controller, such as the Siemens S7-1200 series.

[0020] By adopting the above technical solution, the base 1 provides the installation foundation for the device, and the partition plate 2 forms an independent storage area for different sewing parts by adjusting its position, thus avoiding the mixing of sewing parts; the monitoring component 3 is used to detect whether the retrieval action occurs in the target storage area, the prompting component 4 is used to indicate the current storage area where the item should be retrieved, and the alarm component 5 is used to issue a warning when the item is retrieved incorrectly; the controller, as the core, receives the signal from the monitoring component 3, controls the start and stop of the prompting component 4 and the triggering of the alarm component 5, thereby realizing sequential item retrieval guidance and error prevention.

[0021] In this embodiment, the top of the base 1 is provided with a plurality of slots 101 at equal intervals, and the bottom of the partition plate 2 is integrally formed with a plug 201, which is inserted into the slot 101.

[0022] By adopting the above technical solution, the slot 101 of the base 1 cooperates with the insert 201 of the partition plate 2. By inserting the insert 201 into the slot 101 at different positions, the position of the partition plate 2 on the base 1 can be adjusted, thereby changing the size of the storage area between adjacent partition plates 2 to accommodate sewing parts of different sizes.

[0023] In this embodiment, the monitoring component 3 includes a detection grating 301. The transmitting end and receiving end of the detection grating 301 are respectively set on both sides of the retrieval port in the storage area, and the signal output end of the detection grating 301 is electrically connected to the controller.

[0024] By adopting the above technical solution, the transmitting end of the detection grating 301 continuously emits light signals to the receiving end. When the operator takes the item from the storage area, his hand will block the light signal. The receiving end will send a trigger signal to the controller because it cannot receive the signal. The controller will identify the storage area corresponding to the signal and determine whether the item taking action conforms to the preset sequence.

[0025] Among them, the detection grating 301 can be the EPG10 series safety grating, which has the advantages of strong anti-light interference capability and the fastest response time ≤1ms. It is suitable for sewing parts retrieval scenarios. It is a through-beam structure, which includes separate installation of transmitter / receiver, which conforms to the design of "the transmitter and receiver are set on both sides of the retrieval port in the storage area" in this embodiment.

[0026] In this embodiment, the prompt component 4 includes an indicator light 401, which is located at the lower end of the retrieval port in the storage area and is electrically connected to the controller.

[0027] By adopting the above technical solution, the controller controls the indicator light 401 corresponding to the storage area where the item should be retrieved to light up according to the preset retrieval sequence, visually prompting the operator that the storage area is the target retrieval location and guiding them to retrieve the item correctly.

[0028] In this embodiment, the alarm component 5 includes a speaker 501. A mounting base is fixedly installed on the bottom of the base 1, and the speaker 501 is fixedly installed on the mounting base. The speaker 501 is electrically connected to the controller.

[0029] By adopting the above technical solution, when the monitoring component 3 detects that the operator has taken a piece from the non-indication storage area, the controller sends a signal to the speaker 501, and the speaker 501 sounds an alarm to remind the operator to correct the error.

[0030] In this embodiment, a slide rail 6 is fixedly installed on the side of the base 1 near the retrieval port of the storage area. A first slider 601 corresponding to the transmitting end and receiving end of the detection grating 301 is slidably installed on the slide rail 6. A connecting ear 602 for connecting to the transmitting end or the receiving end of the detection grating 301 is fixedly connected to the first slider 601.

[0031] By adopting the above technical solution, the slide rail 6 provides a sliding track for the first slider 601. The first slider 601 is equipped with the transmitter or receiver of the detection grating 301 through the connecting ear 602. By sliding the first slider 601, the relative position of the transmitter and receiver can be adjusted to ensure that they accurately correspond to the retrieval port of different storage areas and ensure detection accuracy.

[0032] In this embodiment, a handle bolt 603 for fixing the first slider 601 to the slide rail 6 is threaded on the first slider 601.

[0033] By adopting the above technical solution, after the first slider 601 slides to the target position, the handle bolt 603 is tightened so that its end presses against the slide rail 6, and the position of the first slider 601 is fixed by friction, so as to avoid displacement of the transmitting end or receiving end of the detection grating 301 due to vibration and other factors, and to ensure detection stability.

[0034] In this embodiment, a second slider 604 is slidably mounted on the slide rail 6, and an indicator light 401 is fixedly mounted on the second slider 604. Each second slider 604 is disposed between the transmitting end and the receiving end of its corresponding detection grating 301.

[0035] By adopting the above technical solution, the second slider 604 slides on the slide rail 6, which can drive the indicator light 401 to adjust its position so that it accurately corresponds to the retrieval port of its storage area.

[0036] Working principle: 1. Preliminary adjustment: According to the size of the sewing parts, insert the insert 201 of the divider 2 into the appropriate slot 101 on the base 1 to form multiple independent storage areas; slide the first slider 601 on the slide rail 6 to adjust the position of the transmitter and receiver of the detection grating 301 so that they correspond to the retrieval port of each storage area, and tighten the handle bolt 603 to fix it; slide the second slider 604 to make the indicator light 401 align with the retrieval port of the corresponding storage area.

[0037] 2. Part Retrieval Guidance: The controller illuminates the indicator light 401 corresponding to the storage area where the part should be retrieved according to the preset part retrieval sequence, indicating the retrieval location to the operator.

[0038] 3. Motion monitoring: When the operator retrieves an item from the storage area indicated by indicator light 401, the operator's hand blocks the light signal of the detection grating 301 in that area. The receiver sends a signal to the controller. After the controller confirms that the item retrieval is correct and records the action, it controls the indicator light 401 to turn off and triggers the indicator light 401 of the next sequential storage area to light up.

[0039] 4. Error Alarm: If the operator retrieves a piece from a storage area not indicated by indicator light 401, the detection grating 30 in that area will be blocked. The receiver will send a signal to the controller, which will determine that the retrieval is incorrect and immediately trigger the speaker 501 at the bottom of the base 1 to sound an alarm, reminding the operator to correct the error. After the error is corrected, the retrieval will be guided back to the correct order.

[0040] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
