Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to the field of intelligent sewing equipment technology, specifically a dual-station alternating feeding template mechanism for an intelligent sewing workstation. Background Technology

[0002] In the manufacturing of soft materials such as automobiles, clothing, and bags, intelligent sewing workstations have become key equipment for improving production efficiency and reducing labor intensity. These workstations typically integrate functions such as automatic sewing, automatic thread trimming, and automatic pick-up and placement of cut pieces. Among these, efficiently and accurately transporting the cut pieces to be sewn to the designated position under the sewing machine head is one of the core aspects determining the overall operational efficiency of the workstation.

[0003] Traditionally, the feeding of cut pieces is done manually, one piece at a time. The pieces are placed on a specially designed tooling template and positioned to feed them. This feeding method is inefficient, with low efficiency for feeding multiple specifications of products per piece manually. In addition, there is high employee turnover, and new employees have poor skills and cannot keep up with the production pace.

[0004] Specifically, the existing technology has the following drawbacks:

[0005] 1. Low efficiency: The existing single-station feeding template mechanism requires the entire feeding station to stop feeding while the sewing machine is working on a piece of fabric, waiting for the sewing task to be completed. This results in unavoidable waiting time during equipment operation, making it impossible to simultaneously feed fabric and perform sewing, which severely restricts overall production efficiency.

[0006] 2. Insufficient automation: Many traditional solutions still require operators to manually place and position the cut pieces during sewing intervals. This method is not only labor-intensive, but also prone to becoming a bottleneck in the production process due to the unstable rhythm and precision of manual operation, and it is difficult to achieve seamless integration with highly automated sewing workstations.

[0007] 3. Lack of flexibility: Fixed single-station templates are difficult to adapt quickly to flexible production modes with multiple varieties and small batches. When it is necessary to change product styles, it is often necessary to replace or adjust the entire template, resulting in long changeover times and reduced equipment utilization and production flexibility.

[0008] Therefore, there is an urgent need for an automated feeding mechanism with structural optimization to enable continuous operation and effectively shorten the production cycle, so as to meet the high-efficiency and high-flexibility production requirements of modern intelligent sewing workstations. Utility Model Content

[0009] The purpose of this utility model is to provide a dual-station feeding template alternation mechanism for intelligent sewing workstations. This dual-station feeding template alternation mechanism for intelligent sewing workstations aims to solve the technical problems of low efficiency, insufficient automation, and weak flexibility in the prior art.

[0010] This utility model provides a dual-station alternating feeding template mechanism for an intelligent sewing workstation, comprising two opposing supports; a tooling template, including an upper template and a lower template; the upper template and the lower template are arranged parallel to each other, with a gap between them; at least one feeding area is provided on each of the upper and lower templates; a sliding device, including two upper slide rails and two lower slide rails; the two sides of the upper template are respectively connected to the corresponding side supports via an upper slide rail, and the two sides of the lower template are respectively connected to the corresponding side supports via a lower slide rail; a telescopic device, including two upper telescopic cylinders and two lower telescopic cylinders, the cylinder bodies of the two upper telescopic cylinders are respectively fixedly connected to the upper parts of the two opposing sides of the supports, and the cylinder bodies of the two lower telescopic cylinders are also respectively fixedly connected to the lower parts of the two opposing sides of the supports; the extended end of the upper telescopic cylinder is fixedly connected to the front end of the corresponding side of the upper template, and the extended end of the lower telescopic cylinder is fixedly connected to the front end of the corresponding side of the lower template.

[0011] Furthermore, each of the feeding areas has a detection hole; a sensing device corresponding to the position of the detection hole is installed below the feeding area.

[0012] Furthermore, the upper and lower templates have the same structure, both consisting of a template frame and a tooling plate, and the template frame and the tooling plate are detachably connected.

[0013] Furthermore, the template frame is provided with several support beams, which are parallel to the plane of the template frame.

[0014] Furthermore, the tooling plate is provided with at least four feeding areas, and each feeding area is provided with at least one positioning pin.

[0015] Furthermore, the feeding area contains cut pieces to be processed, and at least one brush is arranged around the edge of the cut piece, with the brush head in contact with the edge of the cut piece.

[0016] Furthermore, both the upper telescopic cylinder and the lower telescopic cylinder are pneumatic cylinders.

[0017] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0018] 1. This utility model achieves an alternating operation mode by setting up an upper and lower template to form a dual loading station. When processing the cut piece on one template, the operator can simultaneously prepare for the next loading on the other template. The two workstations alternately enter and exit the work area, eliminating waiting time in the production process, enabling continuous operation of the equipment, shortening the production cycle of a single product, and significantly increasing production capacity.

[0019] 2. This utility model, through the combination of a detection hole and a sensing device, enables the system to automatically detect whether the cut pieces are placed in the correct position, ensuring the accuracy of material feeding and reducing quality problems caused by human error. The entire alternation process is precisely controlled by a telescopic cylinder, ensuring stable and reliable operation, reducing reliance on skilled operators, and achieving efficient integration with intelligent sewing workstations.

[0020] 3. This utility model, through the combination structure of a detachable template frame and tooling plate, makes it quick and convenient to change different styles of tooling plates, enabling rapid response to changes in production tasks and adapting to the production needs of diverse products.

[0026] The following embodiments will further illustrate the present invention, but do not limit the present invention.

[0027] Example 1

[0028] like Figures 1 to 2 As shown, this embodiment provides a dual-station material feeding template alternation mechanism for an intelligent sewing workstation, which consists of two supports 1, a tooling template 3, a sliding device 2, and a telescopic device 4.

[0029] Two supports 1 are set opposite each other. Support 1 serves as the basic support structure of the entire mechanism and is installed parallel and stably on the workbench or frame of the sewing workstation.

[0030] The tooling template 3 includes an upper template and a lower template. The upper template and the lower template are set parallel to each other and maintain a certain distance between them in the vertical direction.

[0031] In this embodiment, the upper and lower templates have identical structures. Each of the upper and lower templates has four feeding areas for placing the cut pieces to be processed. Preferably, each feeding area is equipped with multiple positioning pins 321 for precise positioning of the cut pieces during placement, preventing them from shifting during movement.

[0032] Each feeding area has a detection hole 322. The worktable or frame is equipped with the same number of sensing devices 5 as these detection holes 322. The sensing devices 5 are installed within the working area, below the upper and lower templates. The position of each sensing device corresponds one-to-one with the position of the detection hole 322 on the upper or lower template within the working area, with the sensor probes facing upwards. When the cut piece is correctly placed on the positioning pin 321 in the feeding area, it will block the detection hole 322, allowing the sensing device 5 to detect the signal and determine that the cut piece is in place. Through the cooperation of the detection holes 322 and the sensing devices 5, automatic detection of the feeding status is achieved.

[0033] In this embodiment, the sensing device 5 is a reflective photoelectric sensor. Its working principle is as follows: the sensor is installed below the feeding area, with the transmitter and receiver located within the same housing. The sensor continuously emits a light beam towards the detection hole area directly above. When no cut pieces are placed in the feeding area, the light passes through the detection hole and travels far away, with almost no light reflected back to the receiver; the sensor outputs a "no material" signal. When a cut piece is placed in position and blocks the detection hole, the light shines on the surface of the cut piece at a very close distance, causing diffuse reflection. Some of the light is detected by the receiver, and the sensor switches its state, outputting a "material present" signal. This signal is transmitted to the workstation's control system, which can then accurately determine whether the corresponding cut piece in the feeding area has been placed in position, providing crucial triggering conditions and status information for subsequent workstation alternation and automated processing.

[0034] The sliding device 2 includes two upper slide rails 21 and two lower slide rails 22. The left and right sides of the upper template are slidably connected to the corresponding support 1 via an upper slide rail 21, allowing the upper template to slide back and forth along the upper slide rail 21. Similarly, the left and right sides of the lower template are slidably connected to the corresponding support 1 via a lower slide rail 22, allowing the lower template to slide back and forth along the lower slide rail 22. The upper slide rails 21 and lower slide rails 22 are spatially staggered, do not interfere with each other, and are alternately extended, ensuring that the upper and lower templates can move independently. When the upper and lower templates retract, they are located in the working area; when extended, they are located in the feeding area. The upper and lower templates extend alternately, thus achieving a continuous alternating feeding effect.

[0035] The telescopic device 4 includes two upper telescopic cylinders 41 and two lower telescopic cylinders 42. One upper telescopic cylinder 41 and one lower telescopic cylinder 42 are fixedly mounted on each of the two brackets 1. The extended end of the upper telescopic cylinder 41 is fixedly connected to the front end of the corresponding side of the upper template, and is used to drive the upper template to move back and forth. The extended end of the lower telescopic cylinder 42 is fixedly connected to the front end of the corresponding side of the lower template, and is used to drive the lower template to move back and forth. In this embodiment, both the upper telescopic cylinder 41 and the lower telescopic cylinder 42 are preferably cylinders, which have the advantages of simple structure, rapid action, and convenient maintenance.

[0036] How to use this embodiment:

[0037] Step 1: At the beginning of the mechanism, the upper template is in the retracted state and located in the working area, on which the cut pieces to be processed have been placed; the lower template is in the extended state and located in the feeding area, waiting to be fed.

[0038] Step Two: The workstation begins sewing the cut pieces on the upper template. Simultaneously, the operator places a new cut piece in the loading area of ​​the lower template and positions it using the positioning pin 321. Once the cut piece is in place, it blocks the detection hole 322, triggering a signal from the sensor 5, indicating that loading onto the lower template is complete.

[0039] Step 3: The sewing work on the template is complete.

[0040] Step 4: The control system extends the upper telescopic cylinder 41, pushing the sewn upper template from the upper processing area to the loading area. Then, the control system retracts the lower telescopic cylinder 42, pushing the loaded lower template from below to the sewing processing area.

[0041] Step 5: The workstation begins processing the cut pieces on the lower template. Simultaneously, the operator removes the finished products from the upper template and places new cut pieces to be processed. This cycle repeats, allowing for alternating material feeding and processing between the two workstations, ensuring continuous and uninterrupted production.

[0042] Example 2

[0043] like Figure 3 As shown, this embodiment is a preferred solution of Embodiment 1. The upper and lower templates adopt the same structure, both consisting of a rectangular template frame 31 and a tooling plate 32. The template frame 31 and the tooling plate 32 are fixed by a detachable connection method, such as the engagement of a positioning pin 321. This detachable design allows the tooling plate 32 to be quickly replaced according to the shape and size of different product pieces, enhancing the flexibility of the mechanism and adapting to the production needs of multiple varieties and small batches.

[0044] Several support beams 311 are provided inside the template frame 31. These support beams 311 are preferably made of lightweight, high-strength materials and are fixed inside the frame parallel to the plane of the template frame 31. The function of the support beams 311 is to support the tooling plate 32 above, preventing it from bending or deforming under long-term use or the weight of the cut pieces, ensuring that the tooling plate 32 always remains flat, thereby guaranteeing the accuracy of cut piece positioning and sewing.

[0045] Example 3

[0046] like Figure 4 As shown, this embodiment is a preferred solution of Embodiment 1. After the cut piece to be processed is placed in the feeding area of ​​the tooling plate 32, at least one brush 323 is arranged around the edge of the cut piece. The brush 323 can be fixedly installed on the tooling plate 32, and its position is set so that when the cut piece is positioned by the positioning pin 321, the brush head of the brush 323 can contact the edge of the cut piece and apply slight pressure. This design is particularly effective for soft and easily slippery cut pieces such as textile fabrics. During the high-speed reciprocating motion of the tooling template 3, the brush 323 can effectively press down the edge of the cut piece, preventing it from lifting, shifting, or wrinkling due to inertia or airflow, ensuring the stability and positional accuracy of the cut piece from the feeding station to the processing station, and providing a high-quality prerequisite for subsequent processes.
