Description

Technical Field

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

[0002] Down products are warm clothing made of animal feathers filled in the fabric. When processing down products, the down in the fabric needs to be patted loose after filling the down so that the down can be evenly distributed in the fabric, which is convenient for the subsequent processing of down products. Nowadays, many down products are generally processed by manually patting the down so that it is evenly filled in the fabric. There is also a down patting machine that can pat the down in the fabric of down products loose.

[0003] For example, Chinese patent invention patent CN113229561A discloses a velvet beating machine, which includes a base frame, the upper end of the base frame is fixedly connected to the top frame, a conveyor belt assembly is arranged in the middle of the top of the base frame, the left and right sides of the conveyor belt assembly are fixedly connected to the mounting frame through vertical mounting rods, multiple groups of exhaust rollers are distributed on the inner side of the mounting frame, and two adjacent exhaust rollers are connected by synchronous wheels and synchronous belts, the middle of the front end and the rear end of the top frame are both horizontally fixedly connected to the first bracket, a plurality of second brackets are fixedly connected to the top of the top frame, the lower part of the second bracket is rotatably connected to the rotating rod, the two ends of the first bracket are connected to the mounting beam, the inner sides of the two mounting beams are provided with sliding sleeves, and the sliding sleeves are slidably connected to the sliding rod; the two ends of the rotating rod are respectively connected to the sliding rod through an eccentric swing arm and a stud bolt, the bottom end of the sliding rod is fixedly connected to the beating rod through a connecting piece, and the rotating rod is connected to the reduction motor through a synchronous wheel and a synchronous belt.

[0004] The aforementioned down-beating machine uses only a single beater unit, which fails to evenly deflate down products and can create a closed-off effect in the pressed area. To prevent this, multiple beaters should be used to achieve uniform deflation. For example, Chinese invention patent CN115353063A discloses an AI-powered cotton lint smoothing device and a method for smoothing down products. The device comprises a conveying mechanism, at least one detection mechanism, at least one beating mechanism, and a controller. The conveying mechanism transports down products to processing mechanisms that perform different processes. The detection mechanism detects the lint filling level in different areas of the flattened down product. The detection mechanism includes a light source system, an image acquisition device, and an image analysis system. The beating mechanism selectively beats different sections of the inspected down product on the conveying mechanism. The method for smoothing down products comprises the following steps: deflation, detection, beating, and re-inspection. The device also includes a flattening mechanism for deflation and flattening the incoming down product. The invention solves the problems of poor beating effect, long beating time and high power consumption of traditional cotton beating machines.

[0005] However, the above-mentioned beating method still has the following problems: the beating is complicated and requires multiple exhaust detection and beating re-inspection processes. In addition, compared with cotton down, the existing down is lighter and can flow with the air. After exhaust, the down cannot be driven to be evenly dispersed, and the down beating effect is poor.

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

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0030] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application. Different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, even though the embodiment may not be clearly described in the following text.

[0031] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements described without departing from the scope of the present application. Various examples may appropriately omit, replace, or add various processes or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. In addition, features described in some examples may be combined in other examples.

[0032] Example 1: Figure 1 As shown, Figure 1 This is a flow chart of a method for controlling velvet patting based on a velvet patting machine of the present invention, which is only one embodiment of the present invention. A method for controlling velvet patting based on a velvet patting machine is applicable to a velvet patting device, comprising a support frame and a plurality of velvet patting units extending downward from the support frame, the velvet patting units comprising a telescopic rod extending downward, a driving machine for driving the telescopic rod to extend and retract, a patting arm provided at the bottom end of the telescopic rod, and a horizontally arranged patting rod provided on the lower end surface of the patting arm, and a plurality of sensors are provided on the support frame;

[0033] The support frame is fixedly installed above the down product placement table. After the down products are filled with down, they are transported to the placement table and beaten by the down beating unit on the support frame to make the down evenly distributed before being discharged from the placement table.

[0034] Here, the down-beating unit, under the operation of a driving motor set on a support frame, pushes the telescopic rod extending vertically downward to move up and down, driving the clapping arm at the lower end of the telescopic rod and the clapping rod on the clapping arm to move up and down reciprocatingly, clapping the down products on the placement table;

[0035] Of course, the racket arm is set horizontally, the racket rod is set horizontally and perpendicular to the racket arm, and a racket arm is provided with a plurality of racket rods arranged parallel to each other. The racket rod is an elastic metal part, which can generate elastic oscillation during operation, and the aftershock beats the down and air inside;

[0036] The supporting frame is provided with a controller for controlling the driving machines of the plurality of velvet-beating units to work.

[0037] The following steps are involved:

[0038] S1: When the down product is transported to the bottom of the support frame, the filling position of the down product is obtained, and the down-beating unit located above the filling position is recorded as a marking unit;

[0039] As an optional embodiment of the present application, a camera is provided on the support frame for identifying the label on the down product; when executing step S1, the label on the down product is identified by the camera to obtain the filling position of the down product.

[0040] The above-mentioned label can be an industry label code, barcode or QR code, so that the camera can capture it, and then identify it through the controller, and then obtain the filling position of the down product based on the position and posture of the down product when it arrives under the support frame.

[0041] That is to say, when the down products are transported to the placement table under the support frame, it is necessary to obtain the filling position, perform the down beating operation on the filling position, mark the down beating unit above the filling position, and control it differently from other down beating units.

[0042] When executing step S1, if there is no down-beating unit above the filling position, the down-beating unit closest to the filling position may be selected as the marking unit.

[0043] Generally speaking, the areas that can be flapped by multiple flapping units are connected to each other, which is sufficient to cover and flap any position on the placement table under the entire support frame. It is impossible that there is no flapping unit above the filling position; on the contrary, the flapping areas of multiple flapping units will overlap, causing the filling position to be located in the flapping areas of two flapping units at the same time. At this time, it can be judged based on the center of the flapping area, and the flapping unit with the center of the flapping area closer to the center point of the filling position is recorded as the marking unit.

[0044] In short, when step S1 is executed, there is only one velvet-beating unit recorded as the marking unit.

[0045] S2: Extend and tap the velvet tapping units except the marking unit;

[0046] As an optional embodiment of the present application, the down-beating units other than the marking unit are extended and beat down in order to beat all the air in all other areas of the down product to the filling position.

[0047] Of course, in order to make all the air reach the filling position better, when executing step S2, the distance between each patting unit and the marking unit except the marking unit is obtained, and the patting units are driven in sequence from far to near according to the distance from the marking unit; in this way, the air in all areas is squeezed to the filling position in order from far to near.

[0048] Even if the filling position is not directly below the marking unit, the air can be blown to the place closest to the filling position.

[0049] S3: drive all the velvet-beating units to rise, and at the same time drive the marking units to beat down;

[0050] As an optional embodiment of the present application, all the down-shooting units that have been photographed should be raised just before the marking unit is about to photograph the down product, so that there is no longer any squeezing above the non-filling position area of ​​the down product. At this time, when the marking unit photographs, the air gathered at the filling position will be squeezed and flowed in the direction away from the filling position, thereby driving the small mass of down to be evenly dispersed into the down product with the flow of air.

[0051] It should be noted that when executing step S3, the speed of the marking unit is not less than the speed of any other patting unit, that is, the marking unit is required to pat with a high force, enough to squeeze and pat so that the air flows away from the filling position.

[0052] S4: Obtain the height of the upper surface of each part of the down product;

[0053] As an optional embodiment of the present application, a number of distance sensors facing vertically downward are provided on the support frame, and the heights of all the distance sensors are the same; so that when executing step S4, the heights of the upper surfaces of the down products at various locations are obtained by the distances between each distance sensor and the upper surfaces of the down products directly below it.

[0054] The distance sensor reading is the height of the sensor itself (the distance from the upper surface of the placement table, which is known in advance) minus the distance between the sensor and the upper surface of the down product. This is equivalent to the distance sensor reading being the distance between the upper surface of the down product and the upper surface of the placement table, that is, the thickness of the down product at that location.

[0055] Since the heights of all the distance sensors are known and are the same, a larger distance sensor reading indicates that the down product is located at a higher height below the distance sensor, which means that more air is accumulated there and there is more down there.

[0056] S5: Determine whether the unevenness error of the upper surface of the down product is higher than a predetermined threshold; if so, obtain the down-beating unit above the highest point on the upper surface of the down product as a marking unit, and return to step S2; otherwise, the down-beating is completed.

[0057] As an optional embodiment of the present application, when executing step S5, the flatness error of the upper surface of the down product, that is, the error in the height of the upper surface of the down product at various locations, is calculated as the variance of the reading values ​​of each distance sensor.

[0058] 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 S5, a predetermined threshold is generated based on the product parameters; generally speaking, the thicker the down product, the lower the roughness error requirement, that is, the predetermined threshold can be larger; conversely, the thinner the down product, the smaller the predetermined threshold; for example, the roughness error requirement of down jackets is higher, and the predetermined threshold is smaller; the predetermined threshold of down quilts will be larger.

[0059] Therefore, when executing step S5, if the unevenness error of the upper surface of the down product is higher than the predetermined threshold, the original marking unit mark is deleted, and the down-beating unit closest to the highest point on the upper surface of the down product is obtained and recorded as the marking unit.

[0060] In addition, when executing step S5, after beating the down, the down products are output, sewn and packaged.

[0061] In short, compared with other methods of beating down, when beating down, the present invention not only does not require exhaustion first, but also uses the flow of air to promote the uniform distribution of down. After the beating of down is completed by this method, the staff will sew and exhaust the down products.

[0062] The invention provides a down beating control method based on a down beating machine, which is simple and convenient, adopts multiple groups of down beating units for orderly beating, effectively utilizes the lightness of down, drives air flow by beating down products, drives the down to be evenly dispersed, has good down beating effect, and high down beating efficiency.

[0063] The present invention is not limited to the above specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the present invention.
