Description

Technical Field

[0001] This utility model relates to a barcode picking robot for attaching barcodes to cotton bales. Background Technology

[0002] For example, cotton packaging is the final step in the cotton processing production line. After the lint produced by the cotton processing line is packaged, bagged, and weighed, the information of the cotton bales also needs to be labeled. According to the national standard GB 6975-2013 "Cotton Packaging" and related specifications, cotton bale markings include batch-inspection markings (including cotton origin, cotton processing unit, cotton quality label, batch number, bale number, gross weight, foreign fiber content code, and production date) and bale-by-bale inspection markings (barcodes, with the same content as the previous item). The labels corresponding to this content are referred to as national standards in this field. National standards usually also have three barcodes: one for textile mills, one for inspection agencies, and one for cotton processing plants.

[0003] Because national standards clearly stipulate that information such as placement direction and trademarks can be marked on the surface of packaging bags without affecting the cotton bale markings, the labels used in general national standard packaging are designed and manufactured according to specifications. In order to highlight the information of the cotton processing plant, the cotton bale often has additional information that the cotton processing plant can fill in at its request, such as the aforementioned placement direction, trademarks, and some information from the aforementioned national standard. This label is usually called the factory label. Generally, the factory label and the national standard are collectively referred to as barcodes at cotton processing plants, or simply labels.

[0004] Cotton bales typically have a set of labels at each end (standard cotton bales have defined length, width, and height; the two ends here correspond to the two ends along the length direction. For example, a type I cotton bale has a length × width × height of 1400 × 530 × 700 mm, with a permissible deviation of -30 mm for length, -10 mm for width, 150 mm for height, and ±10 kg for weight; the end faces corresponding to the 530 × 700 mm dimensions are the faces corresponding to the end faces). Each set of labels includes one national standard label and one manufacturer's label. The national standard label is usually printed directly by a national standard label printer after the information of the current bale is complete (mainly gross weight, net weight, and production date; other information is basically the same), printing two national standard labels at a time.

[0005] Currently, the affixing of national and factory labels is generally done manually. Therefore, the two national labels can be picked up and affixed manually, while the barcodes are automatically picked up. However, factory labels are usually generated after the national labels are printed and are printed by a factory label printer. Therefore, the national and factory labels need to be picked up separately in different locations, requiring consideration of more factors when picking up the labels.

[0006] It should be noted that the above background technology is technical information that the inventor has acquired in order to deduce the relevant technical problems or obtained in the process of designing this utility model, and does not mean that the above background technology was already prior art before this utility model application, especially the technical content of the cognition and confirmation of the relevant technical problems. Utility Model Content

[0012] Optionally, the suction cup assembly includes: Screw insert, specifically an external threaded screw insert; A straw is a rigid air tube nested into a threaded sleeve; A suction cup, attached to the lower end of the straw; The first lower nut and the first upper nut mate with the threaded sleeve; Accordingly, the support plate has a light hole for the threaded sleeve to pass through, and the first lower nut is located on the lower side of the support plate, and the first upper nut is located on the upper side of the support plate for adjusting and fixing the threaded sleeve.

[0013] Optionally, the two positioning plates of the two suction cup brackets have different lengths corresponding to the longitudinal direction of the label; The two positioning plates are aligned with the longitudinal center of the label.

[0014] Optionally, the support plate includes a support plate body constituting a planar plate and a connecting plate bent from two opposite sides of the support plate body toward the side where the positioning plate is located; The positioning plate is welded to the end of the connecting plate.

[0015] Optionally, the guide assembly is fixed to the support plate body; The suction cup is mounted on the support plate or on the ear plate formed by further outward extension of both ends of the support plate.

In use, one adsorption component first picks up a label, such as a national standard label, and then moves it to the manufacturer's label printer; the other adsorption component picks up a manufacturer's label, and then affixes the current national standard and manufacturer's label to one end of a cotton bag; then, a second set of labels is picked up and affixed. Overall, the barcode picking robot according to this embodiment of the present invention is suitable for picking up and affixing two types of labels. Attached Figure Description

[0030] To facilitate understanding of this utility model, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a more detailed account of the utility model.

[0031] It is understood that the barcode pickup robot according to the embodiments of this utility model is a component of the labeling machine, but not the entirety of it. Therefore, the barcode pickup robot is suitable for doing certain things, rather than simply relying on what the barcode pickup robot can do. For example, the pickup action obviously requires the use of a robotic arm to drive the barcode pickup robot, rather than relying solely on the barcode pickup robot to complete the pickup action.

[0032] Figure 5 The assembly hole 43 is used for the assembly structure of the barcode picking robot on, for example, a robotic arm, where the barcode picking robot is the end device of the robotic arm.

[0033] In the embodiments of this utility model, the provided barcode picking robot is mainly used for picking up two types of barcodes sequentially. Therefore, the two picking components included in the barcode picking robot should avoid mutual interference and maintain a first distance between them.

[0034] When affixing labels, two labels can be applied together, meaning the pickup surfaces of the two pickup units can be aligned. For example... Figure 1 and Figure 2 The positioning plates 21 at the lower ends of the two first suction cup brackets 2 in the middle can provide two coplanar positioning surfaces.

[0035] Since the printed labels are generally horizontal, the positioning plate 21 mentioned above is also ideally horizontal. The picking action of the suction cup assembly 1, for example, is primarily vertical. Therefore, the initial state of the barcode picking robot when mounted on a robotic arm is roughly such that the suction cup assembly 1 is suitable for vertical movement to achieve the picking action, thus possessing a definite vertical orientation.

[0036] At the same time, the suction surface of the corresponding suction cup component must correspond to a plane, which is a horizontal plane, and front, back, left and right can usually be defined within the horizontal plane.

[0037] Given that there will be differences in front, back, left, and right in different reference frames, for example, for two sets of suction cup components 1, the direction in which they are separated can be defined as the length direction. However, for a single suction cup component 1, the distribution of its multiple suction cups 11 is preferably in the barcode direction, that is, the length direction. The distribution direction of the suction cups 11 can be consistent with or inconsistent with the direction in which the suction cup components 1 are separated, but inconsistency is preferred to reduce space occupation. In the following text, unless otherwise specified, under the condition of the description of an orientation parameter, the other parameters based on that orientation parameter are also determined.

[0038] Furthermore, in the embodiments of this utility model, terms such as up, down, left, right, inside, outside, front, back, and similar expressions are for illustrative and explanatory purposes only, and are intended to prevent misunderstanding by those skilled in the art.

[0039] Similarly, statements that are mutually explanatory, such as vertical or horizontal, are also for the purpose of explanation or clarification.

[0040] In addition, in the field of mechanics, it should be known that the front-to-back direction is also called longitudinal, head-to-tail, or length direction, while the left-to-right direction is also called transverse, width direction, or width direction.

[0041] In addition, to facilitate the description of the relationship between one component or component and another component or component shown in the accompanying drawings, spatially relative terms such as "lower," "upper," and similar terms may be used in embodiments of this invention. It should be understood that the spatially relative terms are intended to cover different orientations of the device during use and operation, in addition to those depicted in the accompanying drawings.

[0042] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0043] Furthermore, as a special note, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] It should be understood that in the field of mechanics, standard geometric terms are typically used to describe approximate mechanical structures, without implying that the mechanical mechanism possesses the exact geometric features corresponding to those terms. For example, a rectangular plate is actually described as a three-dimensional structure based on the characteristics of a planar figure. In the field of mechanics, using a specific explicit feature of a component to describe it is a common descriptive method, but this does not mean that the component necessarily contains the exact geometric shape corresponding to that explicit feature.

[0045] Figure 1 and Figure 2 An example of a barcode picking robot includes a plate-type main frame 4, which is a rectangular plate structure in the figure and is shown separately. Figure 5 In. Figure 5 In the illustrated structure, the bracket 4 is a rounded rectangular structure. In order to reduce weight, except for the area used for connecting with other components, the remaining part forms the weight-reducing process hole 42 shown in the figure.

[0046] exist Figure 5 In the illustrated structure, the main frame 4 of the plate structure is roughly symmetrical in the figure, and a set of guide sleeve positioning and mounting holes 41 are provided at the left and right ends of the figure, while the centrally located assembly hole 43 is used for mounting the barcode picking robot on, for example, a robotic arm.

[0047] The guide sleeve positioning mounting hole 41 is used to install a pair of guide components. The purpose of setting the guide components is to avoid rigid impact when picking up or affixing labels.

[0048] The two guide components are vertically positioned based on the picking action, and are arranged side-by-side between them. Figure 5 In the illustrated structure, the guide positioning mounting holes 41 corresponding to the two guide components are located at both ends of the main frame 4 of the plate structure, thus having a certain distance, denoted as the second distance. This second distance is related to the first distance and is mainly used to avoid motion interference when picking up the two types of labels respectively.

[0049] Accordingly, each guide assembly has a downward reset mechanism. Figure 1 The compression spring mounted on the guide rod body 34 can be seen in the image.

[0050] In addition, compression springs can be replaced with rubber sleeves, which are often used as reset components in the mold machinery field and have a relatively long service life.

[0051] Furthermore, two adsorption components are provided, each corresponding to one of the guiding components, and are installed at the lower end of the guiding component. Accordingly, a first distance is maintained between the two adsorption components.

[0052] Regarding the adsorption component, Figure 1 and Figure 2 The illustrated structure uses a suction cup assembly 1, as shown in the figure, which is mounted on the first suction cup bracket 2 and the second suction cup bracket. It is clearly visible in the figure that there is a significant space between the two suction cup assemblies 1.

[0053] The adsorption component can also be an electrostatic adsorption device, which only requires a predetermined distance between the two electrostatic adsorption devices.

[0054] Regarding the absorption and release, there are two considerations. First, the printed labels are usually adhesive-free labels, but before application, adhesive can be applied to the back of the label using a gluing device, and then it can be applied to one end of a cotton bag. The label adheres to the corresponding end of the cotton bag, and the attraction generated by static electricity is less than the bonding force of the adhesive, so it can detach from the electrostatic adsorption plate when the barcode picking robot moves backward.

[0055] For suction cup 11, it can usually be released by changing the suction tube 12 of suction cup 11 to release air. This is common knowledge in the field of suction cup technology and will not be elaborated here.

[0056] Since most labels are strip-shaped or rectangular with an aspect ratio greater than or equal to 1:1, to simplify the structure, each adsorption component has two suction cups. The two suction cups 11 are located at opposite ends of the label, which is sufficient to ensure reliable label adsorption.

[0057] It should also be noted that the paper used for labels is generally coated paper, thermal paper, or PET, PVC plastic paper, etc., all of which are lightweight materials. In other words, even if the number of suction cups is relatively small, it can still meet the requirement of relatively reliable adsorption.

[0058] In addition, in the embodiments of this utility model, a small suction cup can be used (suction cups with a diameter of 4~80mm are classified as small suction cups in the suction cup classification), but the diameter of the suction cup should be less than or equal to two-thirds of the width of the label to avoid air leakage caused by the suction position deviation.

[0059] exist Figure 4 In the illustrated structure, the suction assembly in the mounting structure of the guide assembly includes a suction cup bracket, which includes: support plate, such as Figure 4 The bow-shaped bracket 25 shown is connected to the lower end of the guide assembly, as in... Figure 4 The guide component mounting hole 24 shown is used to connect with, for example, the guide component mounting hole 24. Figure 6 The screw 33 shown is used for connection.

[0060] in addition, Figure 4The central bow-shaped bracket 25 also has suction cup assembly mounting holes 23 for mounting the suction cup assembly 1 on the suction cup bracket.

[0061] In addition, Figure 4 In the illustrated structure, the suction cup bracket further includes a positioning plate 21, which is parallel to the bracket plate and is a horizontal plate. In the figure, the positioning plate 21 is fixedly connected to the bow-shaped frame 25 that constitutes the bracket plate.

[0062] The positioning plate 21 and the suction cup assembly have suction cup through holes 22 at their vertical alignment positions; correspondingly, the suction cup 11 of the suction cup assembly 1 protrudes downward from the suction cup through holes 22. The presence of the positioning plate 21 is mainly used to prevent overtravel when picking up and affixing barcodes. At the same time, the presence of the positioning plate 21 facilitates the release of the label.

[0063] Furthermore, the suction cup 11 extends downward from the suction cup through hole 22 by 2~5mm. When the label is applied by pressing, for example, when the robotic arm drives the barcode picking robot to retract, the spring-back suction cup bracket can help release the label.

[0064] exist Figure 3 In the illustrated structure, the suction cup assembly includes: Screw insert 13, which is an externally threaded screw insert; while Figure 4 In the illustrated structure, the bow-shaped frame 25 has a suction cup assembly mounting hole 23. This suction cup assembly mounting hole 23 is a smooth hole. After the threaded sleeve 13 is inserted into the suction cup assembly mounting hole 23, it is fixed with a pair of nuts. Figure 3 The first lower nut 14 and the first upper nut 15 shown are located on the lower side of the support plate of the bow-shaped frame 25 and on the upper side of the support plate. The positions of the two nuts can be adjusted according to the site conditions to adjust the amount of the suction cup 11 protruding from the lower side of the positioning plate 21.

[0065] Accordingly, the suction tube 12 of the suction cup 11 is a rigid tube and is nested in the screw sleeve. The connection between the suction tube and the screw sleeve can be, for example, welding or threaded connection. If a threaded connection is used, a set screw is required to lock it from the side or a set nut is used to tighten it.

[0066] The suction cup 11 is obviously located at the lower end of the straw 12.

[0067] For distinction, see Figure 1 and Figure 2 The two positioning plates 21 of the two suction cup brackets have different lengths along the longitudinal direction of the label.

[0068] Accordingly, the two positioning plates are aligned with the longitudinal center of the label to ensure that the two labels are in the predetermined alignment state when applied.

[0069] exist Figure 4 The illustrated structure includes an arc-shaped plate 25 constituting the support plate, comprising a support plate body constituting a flat plate and a connecting plate bent from opposite sides of the support plate body toward the side where the positioning plate 21 is located; correspondingly, the positioning plate 21 is welded to the end of the connecting plate, and obviously the end of the connecting plate is its lower end.

[0070] Regarding the installation method of the guide assembly on the bracket plate, in conjunction with Figure 6 The illustrated structure and the aforementioned description of the installation method of suction cup assembly 1 will not be repeated here.

[0071] In addition, Figure 1 In the illustrated structure, the first suction cup bracket 2 located on the left side of the figure has two ear plates at both ends of the bracket plate for mounting the suction cup assembly 1, so that the distance between the two suction cup assemblies 1 is greater than the distance between the two suction cup assemblies 1 on the second suction cup bracket 2.

[0072] The above description is illustrative in conjunction with the accompanying drawings and is not intended to limit the scope of this utility model. Within the concept of this utility model, the above embodiments or different embodiments can be combined without conflict. Although the utility model has been described in detail in the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
