[0043] like Figures 1 to 10 As shown, a cap sewing device includes a frame 1, on which are arranged...

[0044] A pair of feeding frames 2 are used to store cap sheet raw materials, and a lifting platform 21 is provided inside the feeding frames 2;

[0045] A testing platform 3 is used to test the quality of the cap piece material before sewing and to test the accuracy of its placement. The testing platform 3 is provided with a positioning groove 3a and a camera 31 is provided above the testing platform 3.

[0046] A sewing device 41 is used to sew together two pieces of cap material;

[0050] The unloading mechanism 7 is used to transfer the sewn cap piece to the unloading frame.

[0051] The single-layer peeling mechanism includes a rolling assembly 8 and a separation and conveying assembly 9. The rolling assembly 8 is movably mounted on the frame 1.

The separation and conveying assembly 9 includes a flat support plate 91 that is driven to move by a separation drive device.

[0052] The crushing block 81 is connected to a negative pressure device (the air pipe connected to the negative pressure device is not shown in the figure), and the crushing block 81 is provided with adsorption holes 81b. While the crushing block 81 crushes the cap sheet material, the adsorption holes 81b use negative pressure to adsorb the cap sheet material, so that one end of the top layer of cap sheet material can be more effectively lifted, facilitating the insertion of the flat support plate 91 of the separation conveying component 9, thereby achieving the purpose of separating the top layer of cap sheet material.

[0053] The compaction drive mechanism includes a first cylinder 82, a cam 83 connected to the first cylinder 82, a rotating shaft 84 connected to the cam 83, and a compaction block 81 fixed to the rotating shaft 84. The frame 1 is equipped with a translation cylinder 85, a compaction assembly bracket 86 fixed to the translation cylinder 85, a first vertical cylinder 87 mounted on the compaction assembly bracket 86, and a first mounting seat 88 mounted on the first vertical cylinder 87. The first cylinder 82 is mounted on the mounting seat 88, and the rotating shaft 84 is rotatably engaged with the mounting seat 88. The upper end of the first cylinder 82 is hinged to the first mounting seat 88. The first cylinder 82 drives the cam 83 to rotate, which in turn drives the rotating shaft 84 to rotate, thereby driving the compaction block 81 to rotate. The translation cylinder 85 drives the overall translation of the compaction assembly 8, and the first vertical cylinder 87 drives the lifting and lowering of the compaction assembly 8.

[0054] The separation drive device is a second cylinder 92. The bottom of the flat support plate 91 is fixed with a flat support plate slider 93. The frame 1 is fixed with a slider guide rail 94. The flat support plate slider 93 and the corresponding slider guide rail 94 are in sliding cooperation.

[0055] The feeding conveying mechanism 5 includes a feeding base 51, a feeding horizontal slide rail 52 on the feeding base 51, a feeding slide block 53 on the feeding horizontal slide rail 52, a feeding vertical cylinder 54 fixed on the feeding slide block 53, and a feeding suction head 55 on the feeding vertical cylinder 54. The feeding slide block 53 is driven by the cylinder to move horizontally, and the feeding suction head 55 is connected to a negative pressure device.

[0056] The aforementioned correction and transfer mechanism 6 includes a Y-axis slide rail 61 mounted on the frame 1, a Y-axis slider 62 slidably fitted on the Y-axis slide rail 61, an X-axis slide rail 63 fixed on the Y-axis slider 62, an X-axis slider 64 slidably fitted on the X-axis slide rail 63, a rotatable second mounting base 65 mounted on the X-axis slider 64, a second vertical cylinder 66 mounted on the second mounting base 65, and an adjusting suction head 66a fixed on the second vertical cylinder 66.

[0057] The X-axis slider 64 is provided with a rotation drive device 67, which is connected to the transmission rotation shaft 69 via a synchronous belt 68. The second mounting base 65 is fixed on the rotation shaft 69.

[0058] The length direction of frame 1 is the X-axis (movement from the feeding mechanism to the detection platform 3 is the X-axis direction), the width direction of frame 1 is the Y-axis (i.e., the front side of frame 1 is closer to or further away from it), and the longitudinal direction is the Z-axis. In the adjustment mechanism, movement in the Y-axis direction is achieved through the cooperation of Y-axis slider 62 and Y-axis slide rail 61; movement in the X-axis direction is achieved through the cooperation of X-axis slider 64 and X-axis slide rail 63; and movement in the Z-axis direction is achieved through the second vertical cylinder 66, thereby enabling the adjustment of the adsorption head 66a in spatial position. Additionally, the rotation of the rotating shaft 69, driven by a motor, enables the horizontal rotation of the adjustment adsorption head 66a. This allows for the movement and horizontal rotation of the adjustment adsorption head 66a within space, enabling the adjustment of the placement position of the cap material on the detection platform 3.

[0059] A waste collection box 11 is provided below the table surface of the frame 1, and a waste inlet 11a is provided on the table surface of the frame 1. A baffle 12 is provided on the side of the frame 1 away from the waste blowing device 42 at the waste inlet 11a. This arrangement makes the structure more compact, placing the waste collection box 11 below the table surface to leave space for other mechanisms on the table surface; the baffle 12 ensures that the waste blown away by the waste blowing device 42 can accurately fall into the waste inlet 11a.

[0060] The feeding mechanism 7 includes a feeding base 71, a feeding horizontal slide rail 72 on the feeding base 71, a feeding slide block 73 on the feeding horizontal slide rail 72, a feeding vertical cylinder 74 fixed on the feeding slide block 73, and a feeding suction head 75 on the feeding vertical cylinder 74. The feeding slide block 73 is driven by the cylinder to move horizontally, and the feeding suction head 75 is also connected to a negative pressure device.

[0061] The shapes of the aforementioned adsorption heads (feed adsorption head 55, adjustment adsorption head 66a, and discharge adsorption head 75) are matched with the shape of the cap material.

[0062] Working principle:

[0063] This invention relates to a cap panel sewing device that uses two cap panel materials to be fed simultaneously. Two stacks of multi-layered cap panel materials are placed on a lifting platform 21 corresponding to the feeding frame 2. The lifting platform 21 gradually rises to transport the cap panel materials upwards. Since only the top layer of cap panel material needs to be taken each time it is fed, the top layer of cap panel material needs to be peeled off, thereby achieving the purpose of feeding one cap panel at a time.

[0064] This invention relates to a single-layer peeling mechanism that peels off the top layer of cap material through the cooperation of a crushing component 8 and a separating conveying component 9. The specific process is as follows: A translation cylinder 85 and a first vertical cylinder 87 work together to move the crushing block 81 above the feeding frame 2. As the crushing block 81 descends, the first cylinder 82 drives the rotating shaft 84 to rotate via a cam 83, which in turn drives the crushing block 81 to rotate. This causes the crushing block 81 to rotate and crush the cap material, causing the top layer of cap material near the separating conveying component 9 to lift up. Simultaneously, the suction holes 81b on the crushing block 81 use negative pressure to absorb the lifted cap material. Then, the second cylinder 92 moves the flat support plate 91 to insert below the top layer of cap material, thus peeling off the top layer. At this point, the negative pressure device is turned off, and the top layer of cap material will be laid flat on the flat support plate 91.

[0065] Next, the feeding conveyor 5 operates, driving the feeding suction head 55 to move through the cooperation of the feeding slide 53 and the feeding vertical cylinder 54. The feeding suction head 55 transfers the cap material from the two flat support plates 91 to the detection platform 3, completing the simultaneous feeding of the two cap materials. While the feeding conveyor 5 is operating, the crushing assembly 8 exits the conveying line, and the separation conveyor assembly 9 resets.

[0066] In testing platform 3, visual inspection technology (which is an existing technology) is used to inspect the placement of the cap material and the qualification of the cap material.

[0067] When the feeding conveyor 5 transports the cap piece material from the upstream feeding mechanism to the inspection platform 3, various reasons may cause the cap piece material to fail to be accurately placed in the set position. Therefore, this cap piece sewing device is equipped with an inspection platform 3 to perform a correction operation on the position of the cap piece material before sewing. Specifically, the inspection platform 3 is equipped with a positioning groove 3a, and the position of the positioning groove 3a is the set position where the cap piece material needs to be placed. The camera 31 above the inspection platform 3 captures an image of the inspection platform 3, and the main control board uses image comparison technology in visual inspection technology (image comparison technology is a mature existing technology) to compare whether the position of the cap piece material coincides with the position of the positioning groove 3a to determine whether the cap piece material is placed in the set position. If the position of the cap piece material deviates, the main control board sends a control signal to correct the position of the cap piece material through the correction transfer mechanism 6; to ensure that the cap piece material is placed in the set position, so that the two cap pieces material can be accurately aligned when overlapping and sewing, thereby ensuring the quality of the sewn cap piece product.

[0068] Simultaneously, visual inspection technology (an existing technology already maturely applied in product inspection) is used to inspect whether the cap piece material is qualified. Specifically, the image captured by camera 31 is transmitted to the main control board, which uses visual inspection technology to detect defects, such as checking the integrity of the outer contour of the cap piece material to determine if it has missing corners, and checking the color uniformity of the cap piece material to determine if it is damaged. The manufacturer can design the detection algorithm according to the requirements for the cap piece material. Once the main control board detects that the cap piece material on the current inspection platform 3 is unqualified (i.e., waste), it sends a control signal to start the waste blowing device 42. The air blown out of the air outlet 4a blows the waste towards the baffle 12, and after being blocked by the baffle 12, it falls into the waste frame 11 from the waste inlet 11a. This achieves the purpose of removing waste to ensure the quality of the cap piece products that are subsequently sewn.

[0069] The two cap pieces that have completed position and qualification tests on the testing platform 3 are transferred to the sewing device 41 by the correction and transfer mechanism 6 and stacked together. The sewing device 41 then sews the two cap pieces together to complete the sewing of the cap product.

[0070] Finally, the cap piece is transferred from the feeding mechanism 7 to the feeding frame.

[0071] By repeating this process, the sewing of cap pieces can be automated, freeing up labor, reducing labor intensity, and improving processing efficiency.

[0072] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
