Description

Technical Field

[0001] The present application relates to the field of clothing packaging, and in particular to a clothing sorting and packaging device. Background Art

[0002] After production, the clothes will be put into corresponding plastic bags and labeled with barcodes. Then, after visual inspection to confirm that the clothing packaging information is correct and there is no obvious damage or contamination, they will be packed together and then stored or transported.

[0003] After the bagged clothes are tested, some of them may fail the test, and the bagged clothes that fail the test need to be removed from the corresponding conveyor belt for reprocessing. For example, in a batch packaging equipment for clothing production with publication number CN108275323A, when bagged clothes fail the test, the corresponding bagged clothes will be conveyed on the horizontal wheel for a distance and then conveyed by the corresponding longitudinal wheel, so that the unqualified bagged clothes can be sent to the corresponding centralized location.

[0004] However, some clothes are larger in size, such as winter clothes. After packing, it is difficult to pack a large number of them even if the corresponding plastic bags are as small as possible. For this reason, when packing such clothes, you can choose to put the clothes in vacuum bags and then vacuum them to compress the clothes to a smaller volume, for example, the clothing packaging and transportation process disclosed in Publication No. CN104417935A.

[0005] With regard to the above-mentioned related technologies, it is difficult to directly detect small damages of the vacuum bag during the detection process, so that the vacuum bag is prone to expand during the packing process after vacuuming, thereby reducing the number of clothes that can be packed. Summary of the invention

[0006] In order to promptly detect damage to the vacuum bag during the packaging process so as to prevent the number of packed clothes from being reduced, the present application provides a clothing sorting and packaging device.

[0007] The present application provides a clothing sorting and packaging device that adopts the following technical solution.

[0008] A clothing sorting and packaging device comprises a front conveyor belt for conveying vacuum bags filled with clothing and having passed an outer surface inspection, an air box is provided at the end of the front conveyor belt, a clamping valve device for fixing the position of the air valve of the vacuum bag and a negative pressure air nozzle which can be connected to the air valve of the vacuum bag for vacuuming are provided inside the air box, the air box is provided with an air jet pipe which can deliver carbon dioxide gas toward the outer surface of the vacuum bag, a gas nozzle carbon dioxide sensor which can detect the carbon dioxide concentration in the extracted gas is connected to one side of the air outlet of the negative pressure air nozzle, a sorting device which transmits vacuum bags with different extracted gas inspection results to different subsequent workstations is provided at the opening of the air box for delivering the vacuumed vacuum bags, and the gas nozzle carbon dioxide sensor is electrically connected to a controller which can drive the sorting device to operate.

[0009] By adopting the above technical solution, during the process of evacuating the vacuum bag containing clothes, carbon dioxide gas is sprayed onto the outer surface of the vacuum bag at the same time. However, the concentration of carbon dioxide in the air is generally low. Once there is a hole in the vacuum bag, the carbon dioxide gas is sucked into the vacuum bag and sent out through the negative pressure air nozzle. The carbon dioxide sensor at the air nozzle can easily detect excessively high concentrations of carbon dioxide, indicating that the corresponding vacuum bag has a leak, so that the subsequent sorting device can transport the vacuum bags with different detection results to different subsequent workstations for processing, so as to reduce the possibility of packing damaged vacuum bags and prevent the number of vacuum bags to be packed from being greatly affected.

[0010] Optionally, the air box is provided with a closed air cylinder, a power rod of the closed air cylinder is detachably connected to a closed box that can cooperate with the front conveyor belt to enclose the vacuum bag, and an air outlet of the jet pipe is connected to the interior of the closed box.

[0011] By adopting the above technical solution, the vacuum bag is covered by a sealing box before vacuuming, so that the carbon dioxide sent into the sealing box is not easy to overflow too much, the use of carbon dioxide gas is reduced, and the carbon dioxide concentration in the working environment is not easy to be too high. In addition, the air pressure in the sealing box can be appropriately increased, which helps to quickly allow carbon dioxide gas to enter the vacuum bag when the vacuum bag is damaged.

[0012] Optionally, the valve clamping device includes a valve clamping cylinder detachably connected to a closing box, a spring tube detachably connected to a power rod of the valve clamping cylinder, a pressure measuring rod slidably connected to the spring tube, a first compression spring located in the spring tube, a pressure sensor provided at one end of the pressure measuring rod in the spring tube to detect the pressure applied by the first compression spring, and a pneumatic finger detachably connected to the pressure measuring rod and having a clamp capable of clamping the vacuum bag valve.

[0013] By adopting the above technical solution, when the power rod of the clamp valve cylinder moves a predetermined length, once the pressure value detected by the pressure sensor is too large, the clamp valve cylinder stops moving, so that when there are debris in the squeezed vacuum bag and clothes or there are debris on the front conveyor belt, the clothes and the vacuum bag as well as the clamp valve cylinder and the front conveyor belt are not easily damaged.

[0014] Optionally, the pressure measuring rod is detachably connected to a pressure plate that can be pressed against the periphery of the vacuum bag air valve. The pressure plate is penetrated by a plate hole for the vacuum bag air valve to pass through. The closer the plate hole is to the side of the pneumatic finger, the smaller the cross-sectional area. The plate hole is close to the opening periphery of the pneumatic finger for the vacuum bag air valve to slide through.

[0015] By adopting the above technical solution, the peripheral surface of the vacuum bag air valve tends to be horizontal, so that the vacuum bag air valve tends to be horizontal, and the air valve clamped by the pneumatic fingers can be more accurately aligned with the negative pressure air nozzle.

[0016] Optionally, the spring tube is detachably connected to a nozzle cylinder whose power rod moving direction is consistent with that of the clamp valve cylinder power rod, the negative pressure nozzle is detachably connected to the nozzle cylinder power rod, the negative pressure nozzle air inlet is coaxially sealed and rotatably connected to a threaded sleeve threadedly connected to the vacuum bag air valve, and the nozzle cylinder power rod is detachably connected to a rotating motor that drives the threaded sleeve to rotate.

[0017] By adopting the above technical scheme, after the pneumatic fingers clamp the vacuum bag air valve, the negative pressure air nozzle moves downward and is plugged into the corresponding vacuum bag air valve, so that the negative pressure air nozzle will not move until the valve clamping cylinder has completed the downward movement of a predetermined length, thereby reducing the possibility of the negative pressure air nozzle causing damage to the vacuum bag air valve, and a threaded sleeve is provided on the negative pressure air nozzle for threaded connection with the vacuum bag air valve, so that during the vacuuming process, carbon dioxide that has not passed through the inside of the vacuum bag is not easily directly sucked into the negative pressure air nozzle, thereby reducing the possibility of detection deviation.

[0018] Optionally, the front conveyor belt transmission surface is fixedly connected to an array of four belt blocks in each group, the belt blocks are slidably connected to a pressure block that can press the side of the vacuum bag against the belt blocks, the belt blocks are fixedly connected to an upper block, and a second compression spring is detachably connected between the upper block and the pressure block to force the pressure block to press against the side of the vacuum bag.

[0019] By adopting the above technical solution, the position of the vacuum bag on the front conveyor belt is not prone to large deviations, which helps to accurately connect the negative pressure air nozzle angle to the vacuum bag air valve for plugging and connection.

[0020] Optionally, the front conveyor belt is located at the opening of the air box for delivering the vacuum bags after vacuuming, and is detachably connected to a bag placing plate. The belt block is slidably connected to a forced shifting block that can abut against the bag placing plate. The forced shifting block is fixedly connected to an active rack. A middle gear meshed with the active rack is rotatably connected inside the belt block, and the middle gear is meshed with a passive rack fixedly connected to the edge pressing block. The relative end faces of the forced shifting block and the bag placing plate are both inclined so that the forced shifting block can be pushed by the bag placing plate so that the edge pressing block can be away from the belt block.

[0021] By adopting the above technical solution, when the vacuum bag is moved out of the air box after vacuuming, the forced displacement block moves to the bag placing plate and is pushed, so that the periphery of the vacuum bag is no longer tightly pressed by the edge pressing block and the belt block, so that the vacuum bag can be transferred from the front conveyor belt to the sorting device at this time.

[0022] Optionally, an exhaust pipe is provided at the bottom of the closed box for extracting the gas in the closed box after vacuuming is completed, and the closed box is provided with an in-box carbon dioxide sensor capable of detecting the carbon dioxide concentration in the closed box.

[0023] By adopting the above technical solution, after the vacuum bag is evacuated, the exhaust pipe can suck out the carbon dioxide gas in the closed box, and the carbon dioxide concentration in the closed box is detected by using the carbon dioxide sensor in the box to ensure that the carbon dioxide concentration in the closed box is high before vacuuming and is reduced to a low level before the closed box is removed.

[0024] Optionally, the sorting device includes a sorting plate that receives the items sent out by the front conveyor belt, a conveyor belt that transports qualified products that have passed the inspection, a rotary conveyor belt that transports vacuum bags that have failed the inspection, and a sorting cylinder that drives the sorting plate to move and is electrically connected to the controller, and the sorting plate is located between the conveyor belt for qualified products and the rotary conveyor belt.

[0025] By adopting the above technical solution, the sorting plate can be moved to the qualified product conveyor belt or the rotary conveyor belt according to different detection results, so as to realize the sorting operation of clothes with different detection results.

[0026] Optionally, the sorting cylinder is detachably connected to a fixed base, the base is rotatably connected to two rotating rods for a sorting plate to abut against, the sorting plate is rotatably connected to a power rod of the sorting cylinder, the rotation axis of the sorting plate and the rotation axis of the rotating rod are in the same direction, the two rotating rods correspond one by one and are close to a qualified product conveyor belt and a rotary conveyor belt, and deflection inclined surfaces are formed at the positions where the sorting plate abuts against the two rotating rods, and the closer the two deflection inclined surfaces are to each other, the higher their heights are.

[0027] By adopting the above technical solution, when the sorting plate moves toward the qualified product conveyor belt or the rotary conveyor belt, the side of the sorting plate close to the qualified product conveyor belt or the rotary conveyor belt is flipped downward so that the vacuum bag can fall onto the corresponding qualified product conveyor belt or the rotary conveyor belt.

[0028] In summary, the present application includes at least the following beneficial effects.

[0029] During the process of evacuating the vacuum bag containing clothes, carbon dioxide gas is sprayed onto the outer surface of the vacuum bag at the same time. The concentration of carbon dioxide in the air is relatively low. Once there is a hole in the vacuum bag, the carbon dioxide gas is sucked into the vacuum bag and sent out through the negative pressure air nozzle. The air nozzle carbon dioxide sensor can easily detect excessively high concentrations of carbon dioxide, indicating that the corresponding vacuum bag has a leak. In this way, the vacuum bag can be detected for damage during the vacuuming process, which improves the detection efficiency and reduces the possibility of packing damaged vacuum bags.

DETAILED DESCRIPTION

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] The present application embodiment discloses a clothing sorting and packaging device, referring to Figure 1 , including a front conveyor belt 1 placed on the ground and transmitting the vacuum bags that have been visually inspected in front, an air box 2 is detachably connected to the frames on both sides of the end of the front conveyor belt 1, a closed air cylinder 54 is detachably connected to the top surface of the upper part of the air box 2, and a closed box 55 is detachably connected to the bottom end of the power rod of the closed cylinder 54, and the closed box 55 can cover a vacuum bag.

[0038] Reference Figure 2 and Figure 3 The sealing box 55 is provided with a clamping valve device 3 for fixing the position of the air valve of the vacuum bag and a negative pressure air nozzle 4 that can be connected to the air valve of the vacuum bag. The negative pressure air nozzle 4 can be connected to an external vacuum pump to evacuate the vacuum bag. The clamping valve device 3 includes a clamping valve cylinder 57 that is detachably connected to the top surface of the sealing box 55. The power rod of the clamping valve cylinder 57 is coaxially detachably connected to a spring tube 58. The inner wall of the bottom end of the spring tube 58 is coaxially slidably connected to a pressure measuring rod 59. The bottom end of the pressure measuring rod 59 is detachably connected to a pneumatic finger 56 that can clamp the periphery of the air valve of the vacuum bag. In addition, a first compression spring 41 is provided in the spring tube 58 to force the pressure measuring rod 59 to move downward, and one end of the pressure measuring rod 59 located in the spring tube 58 is detachably connected to a pressure sensor 42.

[0039] Reference Figure 4 The pressure sensor 42 detects the pressure value applied by the first compression spring 41. The pressure sensor 42 and the clamp valve cylinder 57 are electrically connected to the controller 53. When the clamp valve cylinder 57 moves down a predetermined stroke, once the pressure value detected by the pressure sensor 42 exceeds the preset pressure threshold in the controller 53, the clamp valve cylinder 57 stops the extension of the power rod, thereby reducing the possibility of damage to the clothes in the vacuum bag. At the same time, the pressure measuring rod 59 is located in the spring tube 58 at one end with a larger width, so that the pressure measuring rod 59 is not easy to detach from the bottom end of the spring tube 58. In addition, the automatic operation of the present application also relies on the controller 53 to regulate and cooperate according to the established program.

[0040] Reference Figure 3 The bottom end of the pressure measuring rod 59 is detachably connected to a pressure plate 43, which can be pressed tightly against the position where the air valve of the vacuum bag is set, and a plate hole 44 is opened through the pressure plate 43, and the plate hole 44 is for the vacuum bag air valve to pass through, so that the vacuum bag air valve tends to be horizontal, and then the pneumatic finger 56 clamps the horizontal vacuum bag air valve. In addition, the closer the plate hole 44 is to the side of the pneumatic finger 56, the smaller the cross-sectional area is, and the opening periphery of the plate hole 44 close to the pneumatic finger 56 is for the vacuum bag air valve to slide through, so that the position of the vacuum bag air valve is not easy to have a large deviation.

[0041] Reference Figure 1 and Figure 5In order to fix the position of the vacuum bag on the front conveyor belt 1 so that the vacuum bag valve clamped by the pneumatic finger 56 is not prone to position deviation, the transmission surface of the front conveyor belt 1 is evenly fixedly connected with a group of four belt blocks 46, each of which is slidably connected with a pressure block 47 that can approach or move away from the transmission surface of the front conveyor belt 1. The pressure block 47 can cooperate with the belt block 46 to clamp and fix the periphery of the vacuum bag, and the four corners of the vacuum bag are fixed accordingly. The belt block 46 is fixedly connected with an upper block 48, and a second compression spring 49 is detachably connected between the upper block 48 and the pressure block 47, and the second compression spring 49 forces the pressure block 47 to move toward the belt block 46.

[0042] Reference Figure 2 and Figure 4 The closed box 55 is detachably connected with a jet pipe 5 connected to the carbon dioxide gas tank. The jet pipe 5 can be provided with a solenoid valve electrically connected to the controller 53 to realize the connection closing function, so that after the power rod of the clamp valve cylinder 57 completes the downward movement of the predetermined stroke, the jet pipe 5 delivers carbon dioxide gas into the closed box 55. At the same time, the closed box 55 is detachably connected with an in-box carbon dioxide sensor 37 electrically connected to the controller 53, so that the jet pipe 5 stops the delivery of carbon dioxide after the concentration in the closed box 55 reaches a preset value. The preset value of the carbon dioxide concentration in the closed box 55 can be 5% to 10%. And because the density of carbon dioxide is greater than that of air, the height of the in-box carbon dioxide sensor 37 is higher than that of the pneumatic finger 56.

[0043] Reference Figure 3 The spring tube 58 is detachably connected to the air nozzle cylinder 45, and the bottom end of the power rod of the air nozzle cylinder 45 is detachably connected to the negative pressure air nozzle 4. The air inlet at the bottom end of the negative pressure air nozzle 4 is coaxially sealed and rotatably connected to a threaded sleeve 26. The circumferential outer wall of the bottom end of the threaded sleeve 26 can be threadedly connected to the circumferential inner wall of the vacuum bag air valve, and the power rod of the air nozzle cylinder 45 is detachably connected to a rotating motor 25 that can drive the threaded sleeve 26 to rotate through a small reduction gearbox, so that it is not easy to directly inhale carbon dioxide gas outside the vacuum bag during the vacuuming process of the negative pressure air nozzle 4. In addition, the air outlet of the negative pressure air nozzle 4 is also connected to a air nozzle carbon dioxide sensor 51 electrically connected to the controller 53. When the air nozzle carbon dioxide sensor 51 detects that the carbon dioxide concentration in the gas in the vacuum bag extracted by the negative pressure air nozzle 4 exceeds the concentration threshold, it indicates that the corresponding vacuum bag is damaged. And the carbon dioxide concentration threshold of the gas extracted from the vacuum bag can be 0.1% to 0.15%.

[0044] Reference Figure 2The bottom periphery of the closed box 55 is fixedly connected and communicated with an exhaust pipe 36, and the exhaust pipe 36 is communicated with the exhaust fan connected to the controller 53. After the vacuuming is completed, the threaded sleeve 26 starts to rotate to release the connection with the vacuum bag air valve. At the same time, the exhaust pipe 36 can extract the carbon dioxide in the closed box 55, thereby reducing the residual carbon dioxide in the working environment. When the threaded sleeve 26 is connected to the next vacuum bag air valve, it is not easy for too much carbon dioxide gas to exist between the threaded sleeve 26 and the vacuum bag air valve, which helps to reduce the accuracy of the subsequent vacuum nozzle carbon dioxide sensor 51 detection.

[0045] Reference Figure 1 and Figure 5 The edge pressing block 47 is fixedly connected to a passive rack 35 slidably connected to the belt block 46, the passive rack 35 is meshed with a middle gear 33 rotatably connected to the inside of the belt block 46, the middle gear 33 is meshed with an active rack 34 slidably connected to the inside of the belt block 46, and the upper end of the active rack 34 is fixedly connected to a forced shifting block 32 exposed to the belt block 46, and the frames on both sides of the end of the front conveyor belt 1 are detachably connected with an arc-shaped bag placing plate 31, and the end of the bag placing plate 31 close to the air box 2 and the surface of the forced shifting block 32 initially abutting against the bag placing plate 31 are both inclined, so that after the front conveyor belt 1 sends the vacuum bag out of the air box 2, the forced shifting block 32 will contact the bag placing plate 31 and be pushed, so that the edge pressing block 47 is away from the transmission surface of the front conveyor belt 1, so that the vacuum bag is no longer fixed.

[0046] Reference Figure 1 and Figure 4 , a sorting device 52 is installed around the end of the front conveyor belt 1 to transfer the vacuum bags to different subsequent workstations according to whether there are damaged ones. The sorting device 52 includes a base 23 facing the end of the front conveyor belt 1, and two rotating rods 24 are rotatably connected to the upper surface of the base 23, and the rotation axis direction of the rotating rods 24 is consistent with the transmission direction of the front conveyor belt 1. The same sorting plate 38 is abutted on the top of the two rotating rods 24, and the vacuum bags delivered by the front conveyor belt 1 are moved to the sorting plate 38. The base 23 is detachably connected to a sorting cylinder 22 whose power rod moves along the horizontal width direction of the front conveyor belt 1. The sorting plate 38 is rotatably connected to the power rod of the sorting cylinder 22 away from the center point of the vertical plane of the front conveyor belt 1, and the rotation axis direction of the sorting plate 38 is consistent with the rotation axis direction of the rotating rod 24. The surface of the sorting plate 38 abutting against the two rotating rods 24 is formed into a deflection slope 27, and the height of the side close to the two deflection slopes 27 is the highest.

[0047] Reference Figure 1, the ground on both sides of the base 23 is provided with a qualified product conveyor belt 39 and a rotary conveyor belt 21, and the qualified product conveyor belt 39 sends the undamaged vacuum bags to the next station for packing, and the rotary conveyor belt 21 sends the damaged vacuum bags to the next station to take out the clothes from the vacuum bags and recycle them before packing, so that when the sorting cylinder 22 moves toward the qualified product conveyor belt 39, the side of the sorting plate 38 close to the qualified product conveyor belt 39 will move downward, so that the vacuum bags on the sorting plate 38 fall onto the qualified product conveyor belt 39, and vice versa. In addition, rollers or drums can be provided on the surface of the sorting plate 38 so that the vacuum bags containing clothes can slide down more smoothly.

[0048] The implementation principle of a clothing sorting and packaging device of the embodiment of the present application is as follows: the vacuum bag containing clothing, which is clamped by the edge pressing block 47 and the belt block 46 on the front conveyor belt 1 in the previous station, is sent into the air box 2 along with the transmission of the front conveyor belt 1, and then the power rod of the closing cylinder 54 moves down so that the closing box 55 covers the corresponding vacuum bag, and then the power rod of the clamping valve cylinder 57 moves down a predetermined stroke, and then the air valve of the vacuum bag is clamped by the pneumatic finger 56, and then the power rod of the nozzle cylinder 45 is extended and the output shaft of the rotating motor 25 is rotated so that the threaded sleeve 26 moves down and rotates at the same time, so that the threaded sleeve 26 can be tightly connected with the vacuum bag air valve, and then the negative pressure nozzle 4 starts to evacuate. Moreover, after the power rod of the closing cylinder 54 is extended, the jet pipe 5 immediately feeds carbon dioxide gas into the closing box 55 until the carbon dioxide concentration in the closing box 55 reaches the standard. The vacuuming is performed for a predetermined time or stops when the carbon dioxide concentration detected by the nozzle carbon dioxide sensor 51 exceeds the threshold.

[0049] Then, the air nozzle cylinder 45 and the rotating motor 25 are reset, and the exhaust pipe 36 starts to extract the gas in the closed box 55 synchronously, and then the clamping valve cylinder 57 and the closed cylinder 54 are reset, and then the front conveyor belt 1 moves forward the distance between the two adjacent vacuum bags, so that the second vacuum bag moves to the bottom of the closed box 55, and the first vacuum bag moves to the sorting plate 38, and then the sorting cylinder 22 judges whether the carbon dioxide concentration value detected by the air nozzle carbon dioxide sensor 51 exceeds the threshold value, so as to move the corresponding vacuum bag to the qualified product conveyor belt 39 or the rotary conveyor belt 21, so as to continuously package and sort the vacuum bags.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
