Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and in particular to an infrared positioning mechanism for sewing pieces and a bag opening machine for garments. Background Technology

[0002] Traditional garment bag opening machines rely heavily on manual visual alignment or mechanical stops for positioning large cut pieces. Manual alignment, however, is susceptible to operator experience and visual fatigue, resulting in positioning errors typically ranging from 1-3mm. Laser bag opening, on the other hand, requires positional accuracy within 0.5mm, leading to defective products and a yield rate generally around 85%. Mechanical stops, while reliable, have poor adaptability, requiring frequent stop replacements for different sizes and materials. This time-consuming adjustment process, coupled with wear and tear on the stops over time, further exacerbates positioning errors and fails to meet the high efficiency and precision requirements of mass production. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an infrared positioning mechanism for sewing pieces and a bag opening machine for clothing, which has the advantages of improving positioning accuracy and processing efficiency.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution: The first aspect of the present invention discloses a sewing fabric infrared positioning mechanism, comprising: A mounting base for assembly with the frame of the bag-pressing mechanism; The positioning cylinder, which is supported on the fixed base, extends and retracts in a direction perpendicular to the mold core of the bag pressing mechanism. A positioning mounting bracket fixed to the piston rod of the positioning cylinder, the two ends of which extend to the outside of the mold core of the bag pressing mechanism; and, An infrared transmitter is fixed at both ends of the positioning mounting frame and its emission direction is perpendicular to the cut piece of the bag to be opened. When the positioning cylinder extends, it drives the infrared transmitter to move to a position corresponding to the transverse central axis of the mold core of the bag pressing mechanism. The infrared transmitter is used to emit positioning lines to the cut piece of the bag to be opened for positioning.

[0005] To achieve the above technical solution, in the initial state, the positioning cylinder is in a retracted state. During the bag opening operation, upon receiving the infrared positioning command from the bag opening machine, the positioning cylinder extends and drives the positioning mounting frame and infrared transmitter to move. When the positioning cylinder extends to its maximum stroke, the infrared transmitter corresponds to the transverse central axis of the core mold of the bag pressing mechanism. At this time, the infrared transmitter emits a positioning line perpendicular to the surface of the cut piece to be opened, thus accurately positioning the cut piece. After positioning is completed, the positioning cylinder resets, waiting for the next bag opening positioning. Infrared positioning ensures the accuracy of each positioning, avoiding deviations caused by visual positioning or mechanical wear, effectively improving positioning accuracy, and eliminating the need for frequent adjustments and replacements, thereby improving processing efficiency.

[0006] In one embodiment of the present invention, the positioning mounting frame is provided with an assembly block, the assembly block is provided with an assembly groove, and the infrared transmitter is connected to a support rod for positioning and locking with the assembly groove.

[0007] To achieve the above technical solution, the infrared transmitter is installed and positioned by using an assembly block in conjunction with a support rod.

[0008] In one embodiment of this utility model, the support rod is a telescopic rod.

[0009] The above technical solution allows for easy adjustment of the infrared emitter's installation position to accommodate different types of cut pieces.

[0010] In one embodiment of this utility model, the infrared transmitter is connected to a screw base, and the screw base is slidably sleeved on the support rod.

[0011] The above technical solution can also be implemented to adjust the installation position of the infrared emitter to adapt to different types of cut pieces.

[0012] In one embodiment of the present invention, the screw seat includes a first seat body and a second seat body that are rotatably connected to each other. The first seat body is provided with a first insertion hole for inserting a support rod, and the second seat body is provided with a second insertion hole for inserting and fixing the infrared transmitter.

[0013] To achieve the above technical solution, the deflection angle of the infrared transmitter can be adjusted by the relative rotation of the first and second seats, thereby facilitating the maintenance of the vertical position of the infrared transmitter after installation.

[0014] In one embodiment of the present invention, the positioning cylinder is further connected to a limit switch, which is used to generate a trigger signal when the positioning cylinder extends to its maximum stroke.

[0015] Implementing the above technical solution facilitates precise control of the extension position of the positioning cylinder.

[0016] In one embodiment of the present invention, the positioning cylinder is further connected to a one-way throttle valve for controlling the extension and retraction speed of the positioning cylinder.

[0017] The above technical solution is implemented so that the extension and retraction speed of the positioning cylinder can be adjusted as needed.

[0018] In one embodiment of this utility model, the infrared emitter is a visible red light emitter.

[0019] A second aspect of the present invention discloses a garment bag opening machine, comprising: A bag-pressing mechanism, wherein the bag-pressing mechanism is equipped with a sewing piece infrared positioning mechanism as described in the first aspect; and... A tray assembly is used to support and position the cut pieces to be opened, and the bag-pressing mechanism is located directly above the tray assembly.

[0020] To achieve the above technical solution, during the bag opening operation, the operator places the cut piece to be opened on the pallet assembly for positioning. Upon receiving the operation signal from the operator, the control system of the bag opening machine energizes the solenoid valve controlling the positioning cylinder. The piston rod of the positioning cylinder extends, pushing the positioning mounting frame and infrared transmitter towards the mold core of the bag pressing mechanism. When the positioning cylinder extends to its maximum stroke, the infrared transmitter aligns with the transverse central axis of the core mold of the bag pressing mechanism, the positioning cylinder stops moving, and simultaneously, the infrared transmitter emits light perpendicular to the surface of the cut piece to be opened. The positioning line allows for precise positioning of the cut pieces to be opened. The placement of the cut pieces is then fine-tuned according to the positioning line until the preset bag opening positioning mark on the cut piece completely aligns with the positioning line, thus completing the positioning process. After positioning, a "positioning qualified" signal is sent to the bag opening machine's control system. The control system then de-energizes the solenoid valve of the positioning cylinder, causing the piston rod of the positioning cylinder to retract and reset, driving the positioning mounting frame and infrared transmitter back to their initial positions. The infrared transmitter then shuts off, awaiting the next bag opening positioning, while the bag opening machine continues with the subsequent laser bag opening process.

[0021] In one embodiment of the present invention, the bag pressing mechanism is located in a mold core including a mold core for pressing down the bag opening, and the infrared emitters are located on both sides of the mold core.

[0022] As described above, the present invention has the following beneficial effects: This utility model provides an infrared positioning mechanism for sewing pieces and a garment bag opening machine. The infrared positioning mechanism for sewing pieces includes: a fixed base for mounting to the frame of a bag pressing mechanism; a positioning cylinder supported on the fixed base, the positioning cylinder extending and retracting in a direction perpendicular to the mold core of the bag pressing mechanism; a positioning mounting frame fixed to the piston rod of the positioning cylinder, the two ends of the positioning mounting frame extending to the outside of the mold core of the bag pressing mechanism; and an infrared transmitter fixed to both ends of the positioning mounting frame and with its emission direction perpendicular to the piece of fabric to be opened. When the positioning cylinder extends, it drives the infrared transmitter to move to a position corresponding to the transverse central axis of the mold core of the bag pressing mechanism. The infrared transmitter is used to emit positioning lines to the piece of fabric to be opened for positioning. Initially, the positioning cylinder is in a retracted state. During the bag opening operation, upon receiving the infrared positioning command from the bag opening machine, the positioning cylinder extends and moves the positioning mounting frame and infrared transmitter. When the positioning cylinder extends to its maximum stroke, the infrared transmitter aligns with the transverse central axis of the core mold of the bag pressing mechanism. At this time, the infrared transmitter emits a positioning line perpendicular to the surface of the cut piece to be opened, thus accurately positioning the cut piece. After positioning is completed, the positioning cylinder resets, waiting for the next bag opening positioning. Infrared positioning ensures the accuracy of each positioning, avoiding deviations caused by visual positioning or mechanical wear, effectively improving positioning accuracy, and eliminating the need for frequent adjustments and replacements, thus improving processing efficiency.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figures 1 to 4 The first aspect of this utility model provides an infrared positioning mechanism for sewing pieces, comprising: a fixed base 10 for assembly with the frame of a bag-pressing mechanism 50; a positioning cylinder 20 supported on the fixed base 10, the positioning cylinder 20 extending and retracting in a direction perpendicular to the mold core 51 of the bag-pressing mechanism 50; a positioning mounting bracket 30 fixed to the piston rod of the positioning cylinder 20, the two ends of the positioning mounting bracket 30 extending to the outside of the mold core 51 of the bag-pressing mechanism 50; and an infrared transmitter 40 fixed to both ends of the positioning mounting bracket 30 and whose emission direction is perpendicular to the piece 70 to be opened, the infrared transmitter 40 being driven to move to a position corresponding to the transverse central axis of the mold core 51 of the bag-pressing mechanism 50 when the positioning cylinder 20 extends, the infrared transmitter 40 being used to emit a positioning line 71 to the piece 70 to be opened for positioning.

[0031] Specifically, an assembly block 31 is provided on the positioning mounting bracket 30. The assembly block 31 is fastened to the positioning mounting bracket 30 by bolts. The assembly block 31 is provided with an assembly groove 32. The infrared transmitter 40 is connected to a support rod 33 for positioning and locking with the assembly groove 32. The assembly groove 32 is a through hole adapted to the support rod 33. The support rod 33 is inserted into the through hole. A through groove is opened at the bottom of the assembly groove 32. The support rod 33 can be clamped and locked by tightening the bolts at the bottom of the assembly groove 32. The installation and positioning of the infrared transmitter 40 is achieved by the assembly block 31 cooperating with the support rod 33.

[0032] The support rod 33 can be configured as a telescopic rod, which makes it easy to adjust the installation position of the infrared emitter 40 to adapt to different types of cut pieces. Of course, the position of the support rod 33 can also be adjusted by adjusting the depth of the support rod 33 inserted into the assembly slot 32, thereby adjusting the mounting position of the infrared emitter 40.

[0033] Alternatively, the infrared transmitter 40 can be connected to a screw base 41, which is slidably sleeved on the support rod 33. The support rod 33 and the screw base 41 need to have a certain damping friction force so that they will not easily slip after being adjusted to the correct position. With the above settings, the installation position of the infrared transmitter 40 can also be adjusted to adapt to different types of cut pieces.

[0034] Specifically, the screw base 41 may include a first base 411 and a second base 412 that are rotatably connected to each other. The first base 411 is provided with a first insertion hole 413 for inserting the support rod 33, and the second base 412 is provided with a second insertion hole 414 for inserting and fixing the infrared transmitter 40. The deflection angle of the infrared transmitter 40 can be adjusted by rotating the first base 411 and the second base 412 relative to each other, so as to ensure the vertical state of the infrared transmitter 40 after installation.

[0035] The infrared emitter 40 is a visible red light emitter, which can emit visible red light to form a positioning line 71.

[0036] In some embodiments, the positioning cylinder 20 is also connected to a limit switch (not shown in the figure) to generate a trigger signal when the positioning cylinder 20 extends to its maximum stroke. This limit switch is connected to the control system of the bag opening machine to transmit the trigger signal, facilitating precise control of the extension position of the positioning cylinder 20. Simultaneously, the positioning cylinder 20 is also connected to a one-way throttle valve (not shown in the figure) to control the extension and retraction speed of the positioning cylinder 20, allowing adjustment of the extension and retraction speed as needed.

[0037] Initially, the positioning cylinder 20 is in a retracted state. During the bag opening operation, upon receiving the infrared positioning command from the bag opening machine, the positioning cylinder 20 extends and moves the positioning mounting frame 30 and the infrared transmitter 40. When the positioning cylinder 20 extends to its maximum stroke, the infrared transmitter 40 corresponds to the transverse central axis of the core mold of the bag pressing mechanism 50. At this time, the infrared transmitter 40 emits a positioning line 71 perpendicular to the surface of the cut piece 70 to be opened, thus accurately positioning the cut piece 70. After positioning is completed, the positioning cylinder 20 resets, waiting for the next bag opening positioning. Infrared positioning ensures the accuracy of each positioning, avoiding deviations caused by visual positioning or mechanical wear, effectively improving positioning accuracy, and eliminating the need for frequent adjustments and replacements, thus improving processing efficiency.

[0038] Please see Figure 5The second aspect of this utility model provides a garment bag opening machine, including: a bag pressing mechanism 50, on which a sewing piece infrared positioning mechanism as described in the first aspect is mounted; and a support plate assembly 60 for supporting and positioning the garment piece 70 to be opened, with the bag pressing mechanism 50 located directly above the support plate assembly 60. The bag pressing mechanism 50 is located on a mold core 51 including a mold core for pressing down the bag opening, and infrared emitters 40 are located on both sides of the mold core 51. Both the bag pressing mechanism 50 and the support plate assembly 60 are existing structures, the same as in the prior art, and will not be described in detail here.

[0039] During the bag opening operation, the operator places the cut piece 70 to be opened on the pallet assembly 60 for positioning. After receiving the operation signal from the operator, the control system of the bag opening machine energizes the solenoid valve of the positioning cylinder 20, causing the piston rod of the positioning cylinder 20 to extend and push the positioning mounting frame 30 and the infrared transmitter 40 towards the mold core 51 of the bag pressing mechanism 50. When the positioning cylinder 20 extends to its maximum stroke, the infrared transmitter 40 corresponds to the transverse central axis of the core mold of the bag pressing mechanism 50, and the positioning cylinder 20 stops moving. At the same time, the infrared transmitter 40 emits a positioning signal perpendicular to the surface of the cut piece 70 to be opened. Positioning line 71 allows for precise positioning of the cut piece 70 to be opened. The placement of the cut piece 70 is then finely adjusted according to the position of positioning line 71 until the preset bag opening positioning mark of the cut piece 70 is completely aligned with positioning line 71, thus completing the positioning. After positioning, a "positioning qualified" signal is sent to the control system of the bag opening machine. The control system then de-energizes the solenoid valve of the positioning cylinder 20, causing the piston rod of the positioning cylinder 20 to retract and reset, which in turn drives the positioning mounting frame 30 and the infrared transmitter 40 back to their initial positions. The infrared transmitter 40 is then turned off, awaiting the next bag opening positioning, while the bag opening machine continues with the subsequent laser bag opening process.

[0040] This invention uses an infrared transmitter 40 to emit a positioning line 71 for positioning, achieving a positioning accuracy of ±0.1mm, which is far superior to manual positioning accuracy. This ensures accurate positioning during subsequent laser bag opening, increasing product yield from 85% to over 98%. Furthermore, the positioning process can be automated with a control system, eliminating the need for manual intervention and effectively improving production efficiency. Additionally, the telescopic installation of the support rod 33 can accommodate cut pieces of different sizes, reducing the need for frequent component replacements, lowering equipment maintenance costs, and effectively improving equipment adaptability.

[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
