Description

Technical Field

[0001] The present invention relates to the technical field of flocking machines. In particular, the present invention relates to a flocking control method based on a flocking machine. Background Art

[0002] Down products are warm clothes filled with animal feathers in the fabric. When processing down products, after filling the down into the fabric, it is necessary to pat the down in the fabric to make the down evenly distributed in the fabric, which is convenient for the subsequent processing of down products. At present, when many down products are processed, generally manual labor is used to pat the down to make it evenly filled in the fabric. There is also a flocking machine that can pat the down in the fabric of down products.

[0003] For example, Chinese Patent Invention Patent CN113229561A discloses a flocking machine, which includes a chassis. The upper end of the chassis is fixedly connected with a top frame. The middle part of the top of the chassis is provided with a conveyor belt assembly. The left and right sides of the conveyor belt assembly are fixedly connected with mounting frames through vertical mounting rods. Multiple groups of exhaust rollers are distributed inside the mounting frames. Adjacent two exhaust rollers are connected through a synchronous pulley and a synchronous belt. The middle parts of the front end and the rear end of the top frame are both horizontally fixedly connected with a first bracket. A plurality of second brackets are fixedly connected to the inner top of the top frame. A rotating rod is rotatably connected below the second bracket. Both ends of the first bracket are connected with mounting beams. Slide sleeves are distributed inside the two mounting beams. The slide sleeves are slidably connected with slide rods; both ends of the rotating rod are respectively connected with the slide rods through eccentric swing arms and double-headed bolts. The bottom end of the slide rod is fixedly connected with a flocking rod through a connecting piece. The rotating rod is connected with a reduction motor through a synchronous pulley and a synchronous belt.

[0004] The above-mentioned flocking machine only has one flocking part for flocking, and cannot make the down products exhaust evenly. A closed effect may be formed in the pressing area. In order to prevent the formation of a closed effect, multiple groups of flocking parts should be used for flocking to achieve the effect of uniform flocking. For example, Chinese Patent Invention Patent CN115353063A discloses an AI cotton flocking intelligent leveling device and a leveling method for cotton flocking products. The cotton flocking intelligent leveling device includes: a conveying mechanism, at least one group of detection mechanisms, at least one group of flocking mechanisms, and a controller. Among them, the conveying mechanism is used to convey the cotton flocking products to the processing mechanisms for performing different processes. The detection mechanism is used to detect the cotton flocking filling amounts in different regions of the flattened cotton flocking products. The detection mechanism includes a light source system, an image acquisition device, and an image analysis system. The flocking mechanism is used to selectively flock different partitions of the cotton flocking products passing through the detection on the conveying mechanism. The leveling method for cotton flocking products includes processes such as exhaust-detection-flocking-re-inspection, etc.; the device also includes a flattening mechanism for exhausting and flattening the input cotton flocking products. This invention solves the problems of poor leveling effect, long flocking time, and high power consumption of traditional cotton flocking machines.

[0005] However, the above-mentioned fluff-patting method still has the following problems: the patting is complex, requiring multiple exhaust detections and patting re-inspection processes. Moreover, compared with cotton fluff, the existing down is lighter in quality and can flow with the air current. After exhausting, it is unable to drive the even dispersion of the down effectively, resulting in a poor effect of fluff patting.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable fluff-patting control method based on a fluff-patting machine. Summary of the Invention

[0007] The purpose of the present invention is to provide a fluff-patting control method based on a fluff-patting machine, which is simple and convenient, effectively utilizes the light characteristics of down, drives the even dispersion of down by patting the down product to drive the air flow, adopts the orderly patting of multiple groups of fluff-patting units, and adjusts the patting intensity of the fluff-patting units according to the unevenness of the down product, with good patting effect and high patting efficiency.

[0023] Preferably, when performing step S1, the label on the down jacket product is identified by the camera to obtain the product parameters of the down jacket product;

[0024] Before performing step S3, a predetermined threshold value is generated according to the product parameters.

[0034] As a preference of the present invention, when performing step S4, after the effective flapping unit flaps down, delete the marking of the marking unit and return to step S2.

For example, the described method can be executed in a different order from the described order, and various steps can be added, omitted, or combined. In addition, the features described in some examples can be combined into other examples.

[0040] Embodiment 1: As Figure 1 shown, Figure 1The following is a schematic flow chart of a flapping control method based on a flapping machine according to the present invention, which is only one embodiment of the present invention. A flapping control method based on a flapping machine is applicable to a flapping device, and includes a support frame arranged above a flapping platform and a plurality of flapping units extending downwardly on the support frame. The flapping unit includes a telescopic rod extending downwardly, a driving machine for driving the telescopic rod to expand and contract, a flapping arm arranged at the bottom end of the telescopic rod, and a horizontally arranged flapping rod arranged on the lower end surface of the flapping arm;

[0041] The support frame is fixedly installed above the flapping platform of the down product. After the down product is filled with down, it is transported to the flapping platform, and is flapped by the flapping units on the support frame. After the down in the down product is evenly distributed, it is then output from the flapping platform;

[0042] Here, under the operation of the driving machine arranged on the support frame, the flapping unit pushes the telescopic rod extending vertically downward to move up and down, driving the flapping arm and the flapping rod on the flapping arm at the lower end of the telescopic rod to reciprocate up and down, and flapping the down product on the flapping platform;

[0043] Certainly, the flapping arm is horizontally arranged, the flapping rod is horizontally arranged and perpendicular to the flapping arm. A plurality of mutually parallel flapping rods are arranged on one flapping arm to form a regional flapping surface. The flapping rod is made of elastic metal and can generate elastic oscillation during operation to aftershock and flap the internal down and air;

[0044] A controller is arranged on the support frame for controlling the driving machines of a plurality of flapping units to work.

[0045] Moreover, the flapping platform is connected with a conveyor belt; the down product arrives at the flapping platform under the drive of the conveyor belt for flapping. After the flapping is completed, the down product is also output from the flapping platform under the drive of the conveyor belt.

[0046] It includes the following steps:

[0047] S1: When the down product is transported to the flapping platform, obtain the position of the down product as the flapping area; obtain the flapping units above the flapping area as the effective flapping units;

[0048] As an option in the embodiment of the present application, a camera is arranged on the support frame for identifying the down product; when performing step S1, the down product is identified by the camera to obtain the position of the down product.

[0049] Certainly, when performing step S1, the down product is transported to the flapping platform through the conveyor belt; and an induction head should also be arranged above the input port of the flapping platform of the conveyor belt for sensing whether an item arrives at the flapping platform.

[0050] After the item arrives at the flapping platform, the identification of the down product should be carried out first, that is, to determine that the item arriving at the flapping platform is a down product, and then the position of the down product is obtained. The identification method is as follows:

[0051] A production label is set on the down product. The label can be an industry label code, a barcode or a QR code, etc., so as to be easily obtained by the camera, and then sent to the controller for identification. Finally, the color, material and specification parameters of the down product are obtained, and compared with the item parameters obtained by the camera under the support frame. If it is correct, it is determined that the item arriving at the flapping platform is a down product, and the operation can continue. Otherwise, an alarm needs to be issued.

[0052] Generally speaking, the areas that multiple flapping units can flap are connected to each other, which is sufficient to cover and flap any position on the flapping platform under the entire support frame. It is impossible for there to be no flapping unit above the stuffing position. Therefore, there is definitely at least one flapping unit above the flapping area. These flapping units are divided into effective flapping units, and only these effective flapping units need to flap to complete the flapping.

[0053] S2: Obtain the heights of the upper surfaces of each part of the down product, and calculate the unevenness value of the upper surface of the down product;

[0054] As an option in the embodiment of the present application, a plurality of distance sensors perpendicular to the bottom are arranged on the support frame, and the heights of all the distance sensors are the same; so that when performing step S2, the heights of the upper surfaces of each part of the down product are obtained through the distances between each distance sensor and the upper surface of the down product directly below it.

[0055] The reading value of the distance sensor is the height value of the sensor itself (the distance value from the upper surface of the placement table, which is known in advance) minus the distance value between the sensor and the upper surface of the down product. It is equivalent to that the reading value of the distance sensor is the distance value between the upper surface of the down product and the upper surface of the placement table, that is, the thickness value of the down product at that place.

[0056] Since the heights of all the distance sensors are known and the same, the larger the reading value of the distance sensor, the higher the height of the down product below it, which means more air is squeezed here and there is more down here.

[0057] Moreover, when performing step S2, the unevenness value of the upper surface of the down product is also the error of the heights of the upper surfaces of each part of the down product, and the calculation method is the variance of the reading values of each distance sensor.

[0058] The larger the variance value, the greater the difference in height at different positions of the down product, that is, the higher the unevenness value of the upper surface of the down product.

[0059] S3: Determine whether the roughness value is higher than a predetermined threshold; if so, execute step S4; otherwise, execute step S5;

[0060] As an optional embodiment of the present application, if the height difference between different positions of the down product is too large, so that the unevenness value is greater than a predetermined threshold, then the down product needs to be flapped and step S4 needs to be executed; otherwise, flapping is not required and step S5 is executed.

[0061] It is also important to note that when executing step S1, the label on the down product is identified by the camera to obtain the product parameters of the down product; then, before executing step S3, a predetermined threshold is generated based on the product parameters; generally speaking, the thicker the down product, the lower the requirement for the roughness value of its upper surface, that is, the predetermined threshold can be larger; conversely, the thinner the down product, the smaller the predetermined threshold; for example, the requirement for the roughness value of the upper surface of a down jacket is higher, and the predetermined threshold is smaller; the predetermined threshold of a down quilt will be larger.

[0062] S4: generating a patting speed value of the effective patting unit according to the roughness value, driving the effective patting unit to pat, and returning to step S2;

[0063] As an optional embodiment of the present application, if the height difference between different positions of the down product is too large, the effective down beating unit needs to work to beat the down product. However, the beating speed of the effective down beating unit is not the same in all cases. The beating speed should be adjusted according to the actual situation of the down product.

[0064] Here, the faster the effective down-beating unit beats down, it can be understood that the greater the force of its beating is, and the greater the instantaneous pressure generated by its beating on the down product is.

[0065] Therefore, the greater the height difference at different positions of the down product, the faster the required tapping speed of the effective tapping unit. That is, when executing step S4, the tapping speed value v of the effective tapping unit is proportional to the unevenness value A, and the calculation method is as follows:

[0066] v = (AS) * K + b = A * KC

[0067] Where: S is the predetermined threshold, K is the preset parameter (known), b is the correction value (known); C = S *Kb.

[0068] S5: Output the down products from the down beating platform.

[0069] As an optional embodiment of the present application, if the height difference of different positions of the down product is small, so that the unevenness value is less than a predetermined threshold, then there is no need to perform step S5 of beating the down product.

[0070] When executing step S5, since there is no need to beat the down products, the down products are output from the beating platform via a conveyor belt.

[0071] In summary, generally speaking, each time steps S2 to S4 are repeated, the height difference between different positions of the down product becomes smaller, and the speed value of the effective down-beating unit will decrease each time; after the down jacket reaches under the support, the beating intensity of the down-beating unit will change from strong to weak, first, it will beat violently to scatter the down in the filling part as much as possible with the air, and then slowly reduce the beating intensity so that all the down is evenly dispersed in the down product.

[0072] Embodiment 2: Still as Figure 1 As shown, Figure 1 The flowchart of a down beating control method based on a down beating machine of the present invention is only one of the embodiments of the present invention. In a down beating control method based on a down beating machine, when down beating is required, it is performed by multiple effective down beating units. It is necessary to perform orderly beating so that the down can be effectively and evenly dispersed with the air flow. The orderly beating scheme is as follows:

[0073] Solution 1: When executing step S4, the effective fleece-patting unit is driven to perform patting. The specific steps are as follows:

[0074] Obtain a down-beating unit above the highest point on the upper surface of the down product and mark it as a marking unit;

[0075] Here, the highest point on the upper surface of the down product indicates that the most air and down are accumulated here, and the down here needs to be spread out, which actually means squeezing the air here to flow in all directions, driving the down here to spread out with the flow of air;

[0076] Obtain the distance between each valid velvet-patting unit except the marking unit and the marking unit, and sequentially drive all valid velvet-patting units except the marking unit to take pictures according to the distance from the marking unit from far to near;

[0077] Here, the effective down-beating units except the marking units are extended and beat down in order to beat all the air in other areas of the down product to the down squeezing position; in order to make all the air reach the filling position better, the distance between each effective down-beating unit except the marking unit and the marking unit is obtained, and the effective down-beating units are driven to beat down in sequence according to the distance from the marking unit from far to near; in this way, the air in all areas is squeezed to the filling position in the order from far to near;

[0078] After all the effective velvet-patting units except the marking unit have finished photographing, all the effective velvet-patting units are driven to rise, and the marking unit is photographed at the same time;

[0079] Here, it should be that at the moment before the marking unit takes a picture of the down product about to be taken, all the flapping units that have already taken pictures are lifted, so that there is no longer extrusion above the area of the down product where there is no filling. At this time, when the marking unit takes a picture, the air gathered at the filling position will be squeezed and flow away from the filling position, thereby driving the down with small mass to flow evenly and disperse into the down product along with the air flow.

[0080] For the second solution, when performing step S4, drive the effective flapping units to take pictures. The specific steps are as follows:

[0081] Obtain the flapping unit above the highest point on the upper surface of the down product, mark it as the marking unit, and drive the marking unit to take a picture;

[0082] Here, give priority to dispersing the piled-up down so that the down at the piled-up position of the down spreads out in all directions;

[0083] Obtain the distance between each effective flapping unit except the marking unit and the marking unit. Drive all the effective flapping units except the marking unit to take pictures in sequence according to the distance from the marking unit from near to far;

[0084] In this way, the down at the piled-up position of the down effectively flows from the center to the periphery in sequence, achieving the effect of uniform dispersion.

[0085] Among them, before any effective flapping unit takes a picture, lift all the effective flapping units that have already taken pictures; so that the down can freely spread out in all directions.

[0086] In short, the first solution is for the flapping work of a large amount of piled-up down, and the second solution is for the flapping of a small amount of piled-up down. The purpose is to disperse the piled-up down.

[0087] In order to make the dispersion effect of the down in the down product better, the first solution and the second solution should be used together and then make another judgment. The method is as follows:

[0088] Set a second threshold; calculate the corresponding picture-taking speed value of the second threshold, that is, the comparison speed value;

[0089] When the unevenness value is greater than the second threshold, at this time the picture-taking speed value is greater than the comparison speed value, execute the first solution;

[0090] After at least one (one round) of flapping, the unevenness value is less than the second threshold but still greater than the predetermined threshold. At this time, the picture-taking speed value is less than the comparison speed value, execute the second solution;

[0091] After at least one (one round) of flapping again, the unevenness value is less than the predetermined threshold, and there is no need to perform flapping.

[0092] Then, when step S4 is executed, after the effective flapping unit makes a downward flapping motion, the marking by the marking unit is deleted, and the process returns to step S2.

[0093] A flapping control method based on a flapping machine according to the present invention is simple and convenient, effectively utilizes the light characteristics of down, drives the air flow by flapping the down product to drive the even dispersion of down, adopts the orderly flapping of multiple groups of flapping units, and adjusts the flapping intensity of the flapping unit according to the unevenness of the down product, with good flapping effect and high flapping efficiency.

[0094] The present invention is not limited to the above specific embodiments, and various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention shall be included in the protection scope of the present invention.
