[0037] Embodiments

[0038] Reference Figures 1-4 In the present embodiment, a cloth cutting device is proposed, which comprises a workbench 100, a cutting device 200, a suction hood 300 and a brushing device.

[0039] The workbench 100 comprises a working part 110 and an extension part 120, wherein the working part 110 and the extension part 120 can be of an integrated structure, and the upper surfaces of the working part 110 and the extension part 120 can be on the same plane. The working surface 111 of the workbench 100 is the upper surface of the working part 110. The working surface 111 is used for laying cloth. The workbench 100 is provided with a recycling port 130 for recycling leftover materials, wherein the recycling port 130 is located between the working part 110 and the extension part 120. The workbench 100 is provided below with a base 140 for supporting the workbench 100.

[0040] The cutting device 200 is used for cutting cloth, wherein the cutting device 200 is located above the workbench 100. The cutting device 200 can comprise a blade. In other embodiments, for non-woven fabrics such as melt-blown fabrics, the cutting device 200 can also comprise an ultrasonic wave generating device or an infrared ray generating device, which all melt the cloth by high temperature to achieve cutting.

[0041] The suction hood 300 is used for pressing on the cloth synchronously when the cutting device 200 cuts the cloth and sucking the debris generated in the process of cutting the cloth, wherein the suction hood 300 is sleeved outside the cutting device 200. The pressing of the suction hood 300 on the cloth can ensure the flatness of the cloth, avoid wrinkles of the cloth caused by the suction force, thereby ensuring the precision and accuracy of cutting.Figure 1 The cutting device 200 is mounted on the support 201, which can be a cylindrical structure, and the suction cover 300 is sleeved on the support 201 and fixedly connected with the support 201.

[0042] The brushing device is used for cleaning the working surface 111 to sweep the leftover material generated by cutting the cloth into the recycling port 130. Figure 1 The brushing device initially stays at an initial position (i.e., the left end of the working surface 111), and the initial position and the recycling port 130 are located at two ends of the working surface 111. The brushing device includes a mounting frame 410 and bristles 420 arranged below the mounting frame 410. The brushing device is arranged above the working surface 111.

[0043] In order to ensure that the cutting of the cloth and the collection of the debris can be smoothly performed, the structure of the suction cover 300 can be designed as follows.

[0044] As shown in Figure 5 , the suction cover 300 includes a bottom surface 301 facing the workbench 100, and a spherical mounting groove (not shown in the figure) is formed in the bottom surface 301, and a ball 302 is rotatably arranged in the mounting groove. The ball 302 always partially protrudes from the bottom surface 301. The bottom surface 301 is an annular structure, and the balls 302 are multiple and uniformly distributed on the bottom surface 301. When the suction cover 300 presses the cloth, the balls 302 are in contact with the cloth, so that there is a gap between the bottom surface 301 and the cloth.

[0045] By arranging multiple balls 302, uniform pressing of the cloth can be achieved. The number of balls 302 can be set according to actual conditions, such as three, four, five, etc. The balls 302 can have elasticity, which can play a role in protecting the cloth when in contact with the cloth, and the balls 302 can also effectively increase the friction between the cloth when deformed under pressure.

[0046] In this embodiment, the suction cover 300 is in contact with the cloth through the balls 302. When the cloth is cut, the cutting device 200 needs to move relative to the cloth, and due to the presence of the balls 302, the friction can be effectively reduced, thereby avoiding the situation that the cloth is wrinkled due to excessive friction between the suction cover 300 and the cloth.

[0047] If the bottom surface 301 is tightly attached to the cloth without a gap, a vacuum environment will be formed inside the suction cover 300 under the action of suction, at this time, part of the cloth may be sucked into the suction cover 300 under the action of atmospheric pressure, which will cause the cutting device 200 to be unable to normally cut the cloth. In this embodiment, by arranging the balls 302, a gap is formed between the bottom surface 301 and the cloth, thereby avoiding the formation of a vacuum environment inside the suction cover 300, and ensuring the normal progress of the cutting work.

[0048] As Figure 1 and Figure 2 shown, the suction hood 300 is connected with a connecting pipe 310, and the connecting pipe 310 is in communication with a collecting bin 320. The bin wall of the collecting bin 320 is provided with a mounting hole (in Figure 6 which the part in communication with the first end portion I 511 is the mounting hole). Specifically, the extension portion 120 is provided with a connector 330, the connecting pipe 310 is connected with the connector 330, and the connector 330 is in communication with the collecting bin 320 through a conduit 340. In order to facilitate observation of the inside of the base 140, Figure 2 perspective processing is performed.

[0049] The outside of the collecting bin 320 is provided with a suction force generating device 500, and the suction force generating device 500 is arranged inside the base 140. The suction force generating device 500 can include a vacuum pump and the like.

[0050] As Figure 6 shown, the suction force generating device 500 includes a suction port and an exhaust port, and the suction force generating device 500 is provided with a suction pipe 510 and an exhaust pipe 520. When the cutting device 200 cuts the cloth, the suction force generating device 500 works to generate a suction force for sucking the debris in the suction hood 300.

[0051] The suction pipe 510 includes a first end portion I 511 and a first end portion II 512, the first end portion I 511 is in communication with the mounting hole, and the first end portion II 512 is in communication with the suction port. The first end portion I 511 is provided with a filtering structure 530 for filtering the debris. The filtering structure 530 can include a filter screen, a filter membrane and the like. By arranging the filtering structure 530, the debris cannot enter the suction pipe 510, thereby protecting the suction force generating device 500.

[0052] The exhaust pipe 520 includes a connecting end 521, and the connecting end 521 is in communication with the exhaust port. The other end of the exhaust pipe 520 is in communication with the air outlet 170 on the base 140, so as to realize exhaust.

[0053] In order to facilitate cleaning of the debris collected in the collecting bin 320, the base 140 is provided with a first bin door 141 for opening or closing the collecting bin 320. The first bin door 141 can be provided with a first handle 1411, and the first bin door 141 can be opened or closed by holding the first handle 1411 and applying a force.

[0054] When the suction force generating device 500 continuously works, the debris will accumulate at the mounting hole under the action of the suction force, thereby affecting the suction force in the suction hood 300.

[0055] In order to prevent the installation hole and the filter screen from being blocked, the suction device 500 is further provided with an anti-blocking air outlet pipe 540 and an auxiliary suction pipe 550, wherein the air inlet pipe 510 and the air outlet pipe 520 are both in communication with the anti-blocking air outlet pipe 540.

[0056] The anti-blocking air outlet pipe 540 comprises a second end portion I 541 and a second end portion II 542, the second end portion I 541 is connected with the first position on the air inlet pipe 510, and the second end portion II 542 is connected with the second position on the air outlet pipe 520. The auxiliary suction pipe 550 is connected with the third position on the air inlet pipe 510.

[0057] In order to ensure that the debris collection and the installation hole anti-blocking do not interfere with each other, the following settings can be made:

[0058] The air inlet pipe 510 is provided with a first on-off control member 561 for controlling the on-off of the air inlet pipe 510, and the air outlet pipe 520 is provided with a second on-off control member 562 for controlling the on-off of the air outlet pipe 520; wherein the first position is located between the first end portion I 511 and the first on-off control member 561, the second position is located between the connecting end 521 and the second on-off control member 562, and the third position is located between the first on-off control member 561 and the first end portion II 512; the anti-blocking air outlet pipe 540 is provided with a third on-off control member 563 for controlling the on-off of the anti-blocking air outlet pipe 540; and the auxiliary suction pipe 550 is provided with a fourth on-off control member 564 for controlling the on-off of the auxiliary suction pipe 550.

[0059] The first on-off control member 561, the second on-off control member 562, the third on-off control member 563 and the fourth on-off control member 564 can all be solenoid valves, and the first on-off control member 561, the second on-off control member 562, the third on-off control member 563 and the fourth on-off control member 564 can all be electrically connected with a processing device. The processing device can include a microprocessor or a single-chip microcomputer, etc.

[0060] The air inlet pipe 510 and the air outlet pipe 520 are initially in a conductive state, and the anti-blocking air outlet pipe 540 and the auxiliary suction pipe 550 are initially in a cut-off state.

[0061] When the suction cover 300 sucks the debris, the suction cover 300 generates a negative pressure and sucks the debris, the debris flows into the collection bin 320 through the connecting pipe 310 and the conduit 340, wherein the debris is stored in the collection bin 320, and the air sucked into the collection bin 320 is discharged through the air outlet pipe 520 and the air outlet 170. At this time, since the anti-blocking air outlet pipe 540 and the auxiliary suction pipe 550 are both in a cut-off state, the auxiliary suction pipe 550 will not suck air, and the airflow flowing in the air outlet pipe 520 will not flow into the air inlet pipe 510 through the anti-blocking air outlet pipe 540.

[0062] In the embodiment, the suction cover 300 is provided with an air pressure detection device.

[0063] When the suction hood 300 sucks the scraps, the air pressure detection device detects the air pressure value in the suction hood 300 in real time. At this time, the auxiliary suction pipe 550 has no air flow flowing, and the air flow flowing in the exhaust pipe 520 will not flow into the suction pipe 510 through the anti-blocking exhaust pipe 540.

[0064] When the air pressure value detected by the air pressure detection device exceeds the preset pressure value, it means that the negative pressure is insufficient, and it can be judged that the first end portion I 511 is blocked. At this time, the first on-off control member 561, the second on-off control member 562, the third on-off control member 563 and the fourth on-off control member 564 are controlled to make the first end portion I 511 and the second end portion I 512 of the suction pipe 510 be cut off; the exhaust pipe 520 is cut off; the anti-blocking exhaust pipe 540 is turned on; and the auxiliary suction pipe 550 is turned on. At this time, the suction force generating device 500 is still in working state, and the external air flows into the suction port of the suction force generating device 500 through the auxiliary suction pipe 550; the air flow discharged in the exhaust pipe 520 flows into the anti-blocking exhaust pipe 540, and the air flow flows into the first end portion I 511 through the suction pipe 510, thereby blowing away the scraps accumulated on the mounting hole and the filtering structure 530, so as to achieve the effect of dredging and anti-blocking.

[0065] The collection of the scraps is synchronized with the cutting of the cloth, so that the scraps are collected efficiently and are prevented from flying or falling on the working surface 111. The recycling of the scraps is performed after the cutting of the cloth is completed and the finished product is removed from the working surface 111.

[0066] In order to enable the cloth cutting device to automatically complete the recycling of the scraps, the following settings can be made.

[0067] The cloth cutting device further comprises an image acquisition device 600 and a processing device, wherein the color of the working surface 111 is different from the color of the cloth. Taking melt-blown cloth as an example, the color of the melt-blown cloth is usually white, blue or green, and therefore the color of the working surface 111 can be set to yellow, red or black, etc. The image acquisition device 600 can comprise a camera device, and the processing device comprises a microprocessor or a PLC, etc. The image acquisition device 600 is electrically connected to the processing device.

[0068] The image acquisition device 600 is configured to take a picture of the working surface 111 after the cloth is cut, and send the taken picture to the processing device;

[0069] The processing device is configured to analyze the taken picture, and when it is determined that all the finished products obtained by cutting the cloth are removed from the working surface 111, the sweeping device is started to clean the working surface 111.

[0070] Further, the image acquisition device 600 is further configured to capture the working surface 111 when the cloth is laid on the working surface 111, and send the captured initial image to the processing device;

[0071] The processing device is further configured to determine all distribution areas of the finished product on the working surface 111 based on the shape and size of the finished product and the size of the working surface 111; wherein the processing device compares the initial image and the post-cutting image, and determines whether the distribution area is completely covered by the cloth based on the color, and if not, it is determined that the finished product obtained after cutting the cloth is removed from the working surface 111. After the cloth is laid on the working surface 111, the relative position relationship between the cloth and the working surface 111 is determined. Since the shape of the cloth and the shape of the finished product are known, the position relationship between the finished product and the working surface 111 can be determined before cutting, i.e., all distribution areas of the finished product on the working surface 111.

[0072] Before cutting the cloth, the size of the working surface 111, the shape and size of the cloth, and the shape and size of the finished product are determined. The position of the image acquisition device 600 when capturing the initial image and the post-cutting image is the same, so that the efficiency of the judgment and the accuracy of the judgment result can be improved when comparing the initial image and the post-cutting image.

[0073] Reference Figure 7 In one embodiment, the cloth 700 can be cut to obtain three finished products, and the three dashed boxes in the figure correspond to three distribution areas 710, and the distribution area 710 corresponds to one finished product. After the cloth is cut, the obtained finished product is grasped and removed from the working surface 111 by the material collecting manipulator, at this time, the position corresponding to the distribution area is exposed to the working surface 111. Since the color of the working surface 111 is different from the color of the cloth, the processing device can determine whether the distribution area is covered by the cloth. During the removal of the finished product, the offcut may be moved to the position corresponding to the distribution area due to the touch of the finished product. Since the size of the offcut is irregular and significantly smaller than the size of the finished product, by determining whether the distribution area is completely covered by the cloth, it can be determined whether the distribution area is covered by the finished product or the offcut, wherein only when the distribution area is completely covered by the cloth, it means that the finished product corresponding to the distribution area is not removed.

[0074] In order to realize the automation of the cutting work, the following settings can be made.

[0075] In this embodiment, the fabric cutting device further includes a mounting arm 800, which is slidable relative to the worktable 100 in a direction parallel to the X-axis.

[0078] like Figure 1 and Figure 3 As shown, a slide rail 150 is provided on the side of the worktable 100, and a slider 850 is provided on the second arm body 820 of the mounting arm 800. The slider 850 is slidably disposed in the slide rail 150, wherein the slide rail 150 is parallel to the X-axis.

[0079] like Figure 4 As shown, a slide rail 160 is provided on the worktable 100, and a slide block 430 is provided at the end of the brushing device. The slide block 430 is slidably disposed in the slide rail 160. The slide rail 160 is parallel to the X-axis. Specifically, the slide blocks 430 are installed at both ends of the mounting bracket 410, and the slide rail 160 and the slide block 430 correspond one-to-one.

[0080] In this embodiment, the brushing device may be connected to a third linear motion device, which is used to drive the brushing device to move parallel to the X-axis so that the brushing device can brush the working surface 111. Specifically, a handle 440 may be provided on the mounting bracket 410 of the brushing device, and the user may also manually drive the brushing device to move on the working surface 111 to clean the working surface 111.
