Description

Technical Field

[0001] This invention belongs to the field of automated pleating and stacking of fabrics, specifically a visual inspection-based automated production equipment for ribbed cuffs. Background Technology

[0002] When ribbed cuffs are produced automatically, preparation work such as neatly stacking and packaging of the ribbed cuffs is required. The specification of Chinese invention patent CN 103194882 A, published on July 10, 2013, entitled "An Automatic Ribbed Cuff Folding Machine", discloses that "an automatic ribbed cuff folding machine includes an electrical control box for automatically folding ribbed cuffs. The workbench panel on the upper surface of the electrical control box is equipped with: a displacement device, a ribbed cuff fixed-length moving device, a material collection device, a material guide plate device, a cutting device, a ribbed cuff folding device, a ribbed cuff unloading device, a ribbed cuff pressing and releasing device, and a discharge device." Although it can automatically feed, fold, and collect ribbed cuffs, it cannot detect defects such as holes or black spots on the ribbed cuffs. This can easily result in defective ribbed cuffs being mixed in with neatly stacked, qualified ribbed cuffs, which is detrimental to the neat stacking and other packaging work of ribbed cuffs. Summary of the Invention

[0003] Purpose of the invention: To provide an automated production equipment for ribbed cuffs using visual inspection. This equipment detects defects in the ribbed cuffs using a visual inspection device, and separates defective ribbed cuffs by coordinating a ribbed cuff folding device and a ribbed cuff unloading device. This solves the problem that existing automated ribbed cuff folding machines cannot automatically identify qualified and defective products, which is not conducive to the neat stacking of ribbed cuffs in packaging.

[0004] The technical solution of the present invention is: an automatic production equipment for ribbed cuffs with visual inspection, comprising: a displacement device, a ribbed cuff fixed-length moving device, a material collection device, a material guide plate device, a cutting device, a ribbed cuff folding device, a ribbed cuff unloading device, a ribbed cuff pressing and releasing device, a discharge device, and a visual inspection device.

[0005] The visual inspection device is located between the material collection device and the ribbed cuff folding device.

[0006] The visual inspection device is used to detect the ribbed cuffs between the material collection device and the ribbed cuff folding device.

[0007] In a further embodiment, the visual inspection device includes at least four visual cameras, which are circumferentially distributed around the moving path of the guide plate device.

[0008] In a further embodiment, the visual inspection device is disposed between the material collection device and the material cutting device, and can perform visual inspection on the part of the ribbed cuff that will be clamped by the folding device before feeding.

[0009] In a further embodiment, the ribbed cuff folding device includes: a suction mechanism, a clamping mechanism, and a rotating mechanism, with a loading station, a unloading station, and a waste disposal station surrounding the rotating mechanism.

[0010] The suction mechanism is installed on the rotating mechanism, and the clamping mechanism cooperates with the suction mechanism at the feeding station.

[0011] The rotating mechanism is used to drive the suction mechanism to rotate between the loading station, unloading station and waste disposal station.

[0012] When the rotating mechanism moves the suction mechanism carrying waste products to the waste station, the waste products are removed from the suction mechanism. The rotating mechanism drives the suction mechanism to rotate between the loading station, unloading station, and waste station. When the suction mechanism carrying qualified products moves to the unloading station, the qualified products are removed from the suction mechanism. When the suction mechanism carrying waste products moves to the waste station, the waste products are removed from the suction mechanism. This allows qualified products and waste products to be unloaded from the two stations of the folding device separately, solving the problem that even if the existing automatic rib cuff folding machine can distinguish between qualified and waste products, waste products are easily mixed with qualified products.

[0013] In a further embodiment, the suction mechanism includes a suction tube and a suction connector.

[0014] The suction tube is installed on the rotating mechanism, and the feeding station is equipped with a suction connector.

[0015] The suction connector is used to connect to the negative pressure device. The suction connector and the suction tube can be detached and matched. The detachable and matched suction tube and suction connector mean that the suction tube does not need to be constantly connected to the negative pressure tube to follow the rotation mechanism.

[0016] In a further embodiment, the ribbed cuff ejection device includes an ejection mechanism.

[0017] The unloading station is equipped with a material return mechanism, which is used to remove qualified products from the suction mechanism.

[0018] In a further embodiment, the ejection mechanism includes an ejection displacement component and ejection grippers.

[0019] The ejector gripper is mounted on the ejector displacement assembly.

[0020] The ejector gripper includes an inner gripper finger and an outer gripper finger.

[0021] The inner gripper engages with the inner side of the suction mechanism, and the outer gripper engages with the outer side of the suction mechanism. The ejector gripper clamps the product from the inner and outer sides of the suction mechanism through the inner and outer gripper fingers.

[0022] The ejector displacement component is used to drive the ejector gripper to move the product off the suction mechanism. The inner and outer gripping fingers of the ejector gripper apply a force away from the suction tube to the product on both sides of the suction tube, so that the inner and outer sides of the ribbed cuff remain in position during the process of moving off the suction tube. Compared with the rollers in the prior art, this reduces the change in the length of the ribbed cuff on both sides of the suction mechanism, and solves the problem of large dimensional errors in the inner and outer sides of the product that are easily moved out in the prior art.

[0023] In a further embodiment, the discharge device includes a conveyor belt.

[0024] The ribbed cuff pressing and releasing device includes: a positioning mechanism and a transport mechanism.

[0025] The positioning mechanism and the handling mechanism are located above the conveyor belt. The positioning mechanism is used to move the product to a preset position on the conveyor belt, and the handling mechanism is used to press and stack the products on the conveyor belt. The automatic pressing, stacking and transportation of qualified products improves work efficiency.

[0026] In a further embodiment, the alignment mechanism includes a feeding component and a pushing component.

[0027] The unloading component is positioned above the unloading mechanism, and the pushing component is positioned between the unloading mechanism and the conveying mechanism.

[0028] The unloading component is used to move the product on the unloading mechanism onto the conveyor belt, and the pushing component is used to move the product to a preset position on the conveyor belt. The unloading component can improve the separation rate between the unloading mechanism and the product. Then, the pushing plate of the pushing component is used to rigidly push the product to align the product edges. Compared with the existing unloading mechanism that directly places the product on the conveyor belt, the neatness of the product stacking position is improved.

[0029] In a further embodiment, the conveying mechanism includes: a conveying displacement component and a pressing component.

[0030] The pressure component is installed on the conveying and displacement assembly, and the pressure component is used to connect to the negative pressure device.

[0031] The pressing component is equipped with a suction hole. The pressing component adsorbs the product through the suction hole, so that the pressing component can first perform the pressing work and then adsorb the product. Then, the conveying and displacement component moves the product to the stacking position through the pressing component for stacking. Compared with the existing technology where the unloading mechanism directly stacks the product on the conveyor belt and the pressing mechanism directly presses the stacked product, the neatness of the product stacking position is improved.

[0032] The beneficial effects of this invention are as follows: This application, through a visual inspection device, can detect whether there are defects such as holes or black spots on the ribbed cuffs during the folding process of the ribbed cuffs, when the material collection device, the material guide plate device, and the ribbed cuff folding device work together to move the ribbed cuffs. Through improvements to the ribbed cuff folding device, the ribbed cuff unloading device, the ribbed cuff pressing and releasing device, and the discharge device, qualified products and waste products can be separated when defects are detected on the ribbed cuffs. This enables high-speed automated detection and separation of ribbed cuffs, solving the problem that existing automatic ribbed cuff folding machines cannot automatically identify qualified products and waste products, which is not conducive to the neat stacking of ribbed cuffs in packaging.

[0041] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0042] This invention discloses an automated production equipment for ribbed cuffs using visual inspection. The equipment is equipped with a PLC and other control devices, and its components, including motors, cylinders, and sensors, are connected to these control devices. The equipment uses a visual inspection device to detect defects in the ribbed cuffs and then separates the defective cuffs through a combination of a ribbed cuff folding device and a ribbed cuff unloading device. This solves the problem in existing automated ribbed cuff folding machines that cannot automatically identify qualified and defective products, hindering the neat stacking and packaging of ribbed cuffs.

[0043] like Figure 1 The automatic ribbed cuff production equipment shown includes: a displacement device, a ribbed cuff fixed-length moving device, a material collection device 1, a guide plate device, a cutting device 2, a ribbed cuff folding device 3, a ribbed cuff unloading device, a ribbed cuff pressing and releasing device 5, a discharge device 6, and a vision inspection device 7.

No further limitations are imposed here.

[0044] The visual inspection device 7 is located between the material collection device 1 and the ribbed cuff folding device 3.

[0045] The visual inspection device 7 is used to inspect the ribbed cuff between the material collection device 1 and the ribbed cuff folding device 3.

[0046] The visual inspection device 7 includes at least four visual cameras, which are circumferentially distributed around the moving path of the guide plate device. The visual inspection device 7 also includes a light source, which is located to the side of the visual cameras. In a preferred embodiment, the guide plate device and the ribbed cuff folding device 3 cooperate to open the ribbed cuff into a prism structure. The number and position of the visual cameras correspond to the number and position of the prism structure sides of the ribbed cuff.

[0047] like Figure 1 The visual inspection device 7 shown is disposed between the material collection device 1 and the material cutting device 2. In other embodiments, the visual inspection device 7 may be disposed between the material cutting device 2 and the rib cuff folding device 3.

[0048] like Figure 2-6 The ribbed cuff folding device 3 shown includes: a suction mechanism 31, a clamping mechanism 32, and a rotating mechanism 33.

[0049] The rotating mechanism 33 is surrounded by a loading station, a unloading station and a waste disposal station. The rotating mechanism 33 can be a rotating motor or other rotating mechanism 33.

[0050] The suction mechanism 31 is installed on the rotating mechanism 33, and the clamping mechanism 32 cooperates with the suction mechanism 31 at the feeding station.

[0051] The rotating mechanism 33 is used to drive the suction mechanism 31 to rotate between the loading station, the unloading station and the waste station.

[0052] When the rotating mechanism 33 moves the suction mechanism 31 carrying the waste product to the waste station, the waste product is removed from the suction mechanism 31. The waste product can be removed manually or by the unloading mechanism. In this embodiment, the rotating mechanism 33 is equipped with a rotating disk with circuit and air circuit so that the clamping mechanism 32 is connected to the air source and control device.

[0053] The suction mechanism 31 and the clamping mechanism 32 can be the prior art disclosed in Chinese invention patent No. CN 103194882 A, Publication Date: 2013.07.10, Invention Title: An Automatic Folding Machine for Ribbed Cuffs. At least three suction mechanisms 31 can be set up, and at least three suction mechanisms 31 are installed on the rotating mechanism 33. The positions of the three suction mechanisms 31 correspond to the positions of the loading station, unloading station and waste station, respectively.

[0054] like Figure 2-5 The suction mechanism 31 in the illustrated embodiment includes a suction tube 311 and a suction connector 312.

[0055] The suction tube 311 is installed on the rotating mechanism 33, and the feeding station is equipped with a suction connector 312.

[0056] The suction connector 312 is used to connect the negative pressure device. The suction connector 312 and the suction tube 311 can be separated and matched. The suction connector 312 can be installed on the rotating mechanism 33 or set on the side of the suction tube 311. When the suction tube 311 rotates to the feeding station, the suction tube 311 and the suction connector 312 are matched.

[0057] In this embodiment, the suction connector 312 is disposed on the suction displacement assembly, and the suction displacement assembly is disposed at the feeding station.

[0058] The suction displacement component is used to move the suction connector 312 toward the suction cylinder 311, so that the suction connector 312 and the suction cylinder 311 are engaged.

[0059] In this embodiment, the suction mechanism 31 includes at least three suction cylinders 311.

[0060] At least three suction ducts 311 are installed on the rotating mechanism 33, and the positions of the three suction ducts 311 correspond to the positions of the loading station, unloading station, and waste disposal station, respectively. Figure 2 , 3 As shown in Figure 5, there are four suction ducts 311. In the preferred embodiment, the multiple suction ducts 311 are evenly distributed around the circumference.

[0061] like Figure 1 , 2 The unloading station of the ribbed cuff folding device 3 shown in Figure 5 is equipped with a first unloading mechanism 4, which is used to remove qualified products from the suction mechanism 31.

[0062] In a preferred embodiment, the waste station of the ribbed cuff folding device 3 is provided with a second unloading mechanism 8, which is used to remove the waste product from the suction mechanism 31.

[0063] The second material return mechanism 8 can be the prior art disclosed in Chinese invention patent No. CN 103194882 A, Publication Date: 2013.07.10, Invention Title: An Automatic Ribbed Cuff Folding Machine.

[0065] The ejector gripper 42 is mounted on the ejector displacement assembly 41.

[0066] The ejector gripper 42 includes an inner gripper finger and an outer gripper finger.

[0067] The inner gripper finger engages with the inner side of the suction mechanism 31, and the outer gripper finger engages with the outer side of the suction mechanism 31. The ejector gripper 42 clamps the product from the inner and outer sides of the suction mechanism 31 through the inner and outer gripper fingers.

[0068] The ejector displacement assembly 41 is used to drive the ejector gripper 42 to remove the product from the suction mechanism 31.

[0069] In a preferred embodiment, the cross-section of the suction duct 311 is a rectangle with a horizontal spacing greater than its vertical spacing, such as... Figure 6 The two ejector claws 42 shown cooperate with the left and right ends of the suction tube 311 respectively, so that the left and right ends of the ribbed cuff in the width direction can be moved out of the suction tube 311 at the same time, further reducing the product shape error of the ribbed cuff.

[0070] like Figure 2 The discharge device 6 shown includes a conveyor belt, and the rib cuff pressing and discharging device 5 includes an aligning mechanism 51 and a conveying mechanism 52.

[0071] The positioning mechanism 51 and the handling mechanism 52 are disposed above the conveyor belt. The positioning mechanism 51 is used to move the product to a preset position on the conveyor belt, and the handling mechanism 52 is used to press and stack the product on the conveyor belt.

[0072] In this embodiment, the discharge device 6 and the rib cuff pressing and releasing device 5 are set at the unloading station of the rib cuff folding device 3. The discharge device 6 includes two conveyor belts, and the conveying mechanism 52 is used to move the product from one conveyor belt to another, which can improve efficiency by simultaneously shaping and conveying the product.

[0073] like Figure 2 The alignment mechanism 51 shown includes: a feeding component 511 and a pushing component 512.

[0074] The unloading component 511 is disposed above the unloading mechanism, and the pushing component 512 is disposed between the unloading mechanism and the conveying mechanism 52.

[0075] The unloading component 511 is used to move the product on the unloading mechanism onto the conveyor belt, and the pushing component 512 is used to move the product to a preset position on the conveyor belt. The pushing component 512 includes a pushing cylinder and a pushing plate. The pushing plate is installed on the unloading cylinder. The length of the pushing plate is greater than or equal to the width of the product. The pushing plate is used to push the product towards the baffle.

[0076] like Figure 7 The conveying mechanism 52 shown includes: a conveying displacement assembly 521 and a pressing component 522.

[0077] The pressure component 522 is installed on the conveying and displacement assembly 521, and the pressure component 522 is used to connect the negative pressure device.

[0078] The pressing component 522 is provided with a suction hole, through which the pressing component 522 adsorbs the product.

[0079] The conveying and displacement component 521 is used to drive the pressing component 522 to press and convey the product. The pressing component 522 is provided with a flexible material below it, which can be a flexible material such as sponge.

[0080] In the above embodiments, the displacement assembly may include linear displacement components such as a lead screw mechanism, a cylinder, or an electric cylinder. The transport displacement assembly 521 is a two-axis displacement mechanism including a lifting cylinder and a transverse lead screw mechanism, based on existing technology, such as... Figure 1 The diagram also shows the use of an electric cylinder as a displacement device.

[0081] Instructions for use: At the feeding station of the rib cuff folding device 3, the suction displacement component drives the suction connector 312 to cooperate with the suction tube 311. The displacement device, rib cuff fixed length moving device, material collection device 1 and guide plate device of the automatic rib cuff production equipment cooperate to move the rib cuff through the cutting device 2 to the rib cuff folding device 3, so that the clamping mechanism 32 clamps the rib cuff. Then the material collection device 1 and guide plate device are reset. During this process, the vision inspection device 7 inspects the rib cuff, and the control device determines whether the rib cuff is a qualified product or a waste product. Then the cutting device 2 cuts the rib cuff. Then the negative pressure device generates negative pressure in the suction tube 311 to suck the part of the rib cuff near the cutting device 2 into the suction tube 311.

[0082] At the unloading station of the rib cuff folding device 3, the first unloading mechanism 4 clamps the product from the inside and outside of the suction mechanism 31 and removes the qualified product from the suction mechanism 31. Then, through the alignment mechanism 51 and the conveying mechanism 52 of the rib cuff pressing and unloading device 5, and the working cooperation of the conveyor belt of the unloading device 6, the product is pressed and stacked.

[0083] At the waste station of the ribbed cuff folding device 3, the second unloading mechanism 8 removes the waste products from the suction mechanism 31. A waste bin or waste channel can be set below the second unloading mechanism 8 at the waste station to collect or discharge the waste products.

[0084] By cooperating with the rotating mechanism 33 of the ribbed cuff folding device 3 and multiple suction mechanisms 31 or multiple suction tubes 311, the work of the loading station, unloading station and waste station can be carried out simultaneously.

[0085] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
