Description

Technical Field

[0001] This utility model relates to the field of cutting bed technology, and in particular to an automatic detection and correction mechanism for the width of cutting blades used in cutting beds. Background Technology

[0002] A cutting table is a large machine tool commonly used in garment factories, primarily employing vibrating straight blades to cut fabric. The cutting table's control system optimizes the cutting trajectory based on the blade width. However, this production method has some problems. If the blade width parameter in the control system does not match the actual blade width, significant cutting errors will occur. This is especially problematic when processing garments with high quality requirements, such as underwear, briefs, and bras, leading to quality issues such as cutting deviations at the notch position and overcutting.

[0003] To address this, as disclosed in publication number CN113652853A, a width detection device for a cutting blade used in a cutting bed includes a linear drive mechanism, a measuring mechanism, and a controller. The linear drive mechanism is fixedly installed, and the measuring mechanism, which is a contact position sensor or a contact displacement sensor, is mounted on the movable end of the linear drive mechanism and contacts the cutting blade under the drive of the linear drive mechanism. The controller is connected to the rotating mechanism, the linear drive mechanism, and the measuring mechanism. The advantage of this invention is that by having the measuring mechanism directly contact the cutting blade, the actual width of the cutting blade can be measured quickly and accurately, unaffected by other environmental factors, providing accurate blade width parameters for the cutting bed, thereby improving the cutting quality and reducing cutting errors.

[0004] However, the detection mechanism of the aforementioned cutting blade is integrated and installed on the cutting head, moving synchronously with the cutting blade. Because the cutting head needs to perform reciprocating operations, it is frequently subjected to impacts, which can lead to inaccurate positioning of the integrated detection mechanism during long-term use and make it inconvenient for later maintenance. In addition, integrating the detection mechanism into the cutting head makes the overall installation relatively complex and the manufacturing cost relatively high, and it cannot be used for upgrading and modifying ordinary cutting beds, resulting in significant limitations in its application. Utility Model Content

[0005] To address the aforementioned issues, this utility model aims to provide an automatic detection and correction mechanism for the width of cutting blades used in cutting beds. It adopts an external detection base station structure, which can improve product adaptability and has good detection accuracy.

[0006] The technical problem solved by this utility model can be achieved by the following technical solution: An automatic detection and correction mechanism for the width of a cutting blade on a cutting bed includes a cutting bed, a cutting machine frame on the cutting bed, a cutting blade assembly on the cutting machine frame, and a detection base station located in the cutting bed. The detection base station includes a base station base and a detection sensor disposed on the base station base. The sensing area of ​​the detection sensor overlaps with at least one coordinate point of the cutting blade assembly along the travel trajectory of the cutting bed.

[0007] When the cutting blade assembly moves to the sensing area where the detection sensor is located, the detection sensor senses and detects the blade width dimension of the cutting blade in the cutting blade assembly.

[0008] The cutting machine frame includes walking frames on both sides and a crossbeam frame between the two walking frames. The crossbeam frame has a mounting part on the side wall adjacent to the cutting blade assembly, and the base station is fixedly installed on the mounting part.

[0009] The mounting section is provided with a receiving cavity.

[0010] The cutting bed includes a fabric covering surface and a machine edge frame, on which an assembly part is provided, and the base station is fixedly installed on the assembly part.

[0011] It also includes a correction module. The detection sensor is used to periodically or irregularly detect and collect data on the blade width dimension of the cutting blade and transmit it to the correction module. The correction module is used to adaptively correct the cutting path of the cutting blade in the cutting blade assembly.

[0012] The correction module is located inside the control terminal.

[0013] Any one of the following: laser sensor, displacement sensor, photoelectric sensor, or CCD camera.

[0014] The advantages of this utility model over the prior art are as follows: This utility model adopts an optimized external detection base station structure, which can be installed in a corresponding position according to the cutting bed specifications and usage, thereby improving product adaptability; in addition, the external fixed-point installation makes it less susceptible to interference and has good detection accuracy.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] Combination Figures 1 to 6 As shown, this utility model discloses an automatic detection and correction mechanism for the width of a cutting blade on a cutting table, including a cutting table 300, a cutting machine frame 310 on the cutting table 300, and a cutting blade assembly 100 on the cutting machine frame 310. The cutting machine frame 310 includes a traveling frame 312 located on both sides and a crossbeam frame 311 located between the two traveling frames 312. Traveling tracks 314 are correspondingly provided on both sides of the cutting table 300, and the traveling tracks 314 and the crossbeam frame 311 are correspondingly matched, so that the crossbeam frame 311 can reciprocate along the traveling tracks 314. The cutting blade assembly 100 is located on the crossbeam frame 311, and a crossbeam track 313 is correspondingly matched on the crossbeam frame 311. The cutting blade assembly 100 can move along the crossbeam track 313. Combined with the cutting blade assembly 100 itself, it can realize the longitudinal movement of the cutting blade 101, realizing three-axis movement. The above-mentioned three-axis movement structure is a feature of the existing design structure of the cutting table 300, and will not be described in detail here.

[0019] In conjunction with the above, this embodiment preferably includes a detection base station 200 located within the cutting bed 300. The detection base station 200 includes a base station base 210 and a detection sensor 220 mounted on the base station base 210. The sensing area of ​​the detection sensor 220 overlaps with at least one coordinate point along the travel path of the cutting blade assembly 100 along the cutting bed 300. The detection sensor 220 within the detection base station 200 is used to detect the blade width of the cutting blade 101 in the cutting blade assembly 100. When the cutting blade assembly 100 travels to the sensing area of ​​the detection sensor 220, the detection sensor 220 senses and detects the blade width of the cutting blade 101 in the cutting blade assembly 100, thereby enabling periodic or irregular blade width detection of the cutting blade 101. The detection time cycle can be set independently according to product usage requirements, thus continuously correcting the cutting trajectory and improving cutting accuracy.

[0020] In one preferred embodiment, a mounting portion 301 is provided on the side wall of the crossbeam frame 311 adjacent to the cutter assembly 100, and the base station base 210 is fixedly mounted on the mounting portion 301. The mounting portion 301 is fixedly mounted to the base station base 210, and the detection sensor 220 is mounted on the base station base 210. The side wall mounting structure is optimized, and preferably, a receiving cavity 302 is provided in the mounting portion 301. The receiving cavity 302 facilitates the internal installation of the detection sensor 220, avoids interference with the lateral movement of the cutter assembly 100, and is optimized to be integrated on the crossbeam frame 311, making the cutter assembly 100 easier to detect and shortening the detection cycle.

[0021] In one preferred embodiment, the cutting bed 300 includes a fabric covering surface 320 and a machine side frame 330. An assembly part 303 is provided on the machine side frame 330, and the base station base 210 is fixedly installed on the assembly part 303. The assembly part 303 is provided on the machine side frame 330 so that the detection base station 200 can be adaptively configured and can be matched with the existing cutting bed 300 for upgrade and optimization, thereby improving the product's adaptability.

[0022] Preferably, it also includes a correction module 410, which is located within the control terminal 400, typically in the control computer. The correction module 410 is a commonly used technology in the prior art, such as the Kawakami GP-50 / 70 cutting machine system, ZOLLER pilot 3.0, ZOLLER pomsoft, and SmartCUT Pro, all of which integrate corresponding correction modules. The detection sensor 220 can be any one of a laser sensor, displacement sensor, photoelectric sensor, or CCD camera. By combining different detection sensors, inductive detection, contact detection, or image recognition detection can be achieved, thereby obtaining real-time blade width data. After continuous feedback, the correction module is used to make corrections, thereby improving the accuracy of the cutting blade movement.

[0023] The detection sensor 220 is used to periodically or irregularly detect and collect data on the blade width dimension of the cutting blade 101 and transmit it to the correction module 410. The correction module 410 is used to adaptively correct the cutting trajectory of the cutting blade 101 in the cutting blade assembly 100.

[0024] This utility model adopts an optimized external detection base station structure, which can be installed in a corresponding position according to the cutting bed specifications and usage, thereby improving product adaptability; in addition, the external fixed-point installation makes it less susceptible to interference and has good detection accuracy.

Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
