[0081] 100 Tube 200 Label DETAILED DESCRIPTION

[0082] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0083] The tube labeling apparatus and method according to the present application are described below with reference to the accompanying drawings.

[0084] Currently, within the hydraulic hose assembly industry, assembly markings are primarily categorized into intrinsic marking and additional marking. In-line marking refers to markings applied physically or chemically to the product itself. Common examples include ink printing and laser engraving. Additional marking involves physically attaching other information carriers to the product, often using self-adhesive labels or cable tie tags. Regarding intrinsic marking, ink printing technology suffers from low marking efficiency, poor flexibility, and high requirements for ink properties and printed surface quality, making it unsuitable for multi-product production. Laser engraving offers a longer shelf life but suffers from poor readability, making it difficult to exchange information using information technology hardware. Regarding additional marking, conventional self-adhesive labels are often applied to the hose using a wrap-around method, making them difficult to read. Due to the complex operating conditions of the hose, labels often fall off or become damaged, resulting in incomplete product information. Furthermore, manual labeling requires locating and verifying the label's consistency with the product, resulting in inefficiencies and impracticality for mass production.

[0085] In view of this, the present application discloses a pipe labeling device for printing the label of pipes, folding and pasting them. Taking the hydraulic hose assembly as an example, it can form Figure 1 The hydraulic hose assembly shown has a folded label. The label 200 is a long label with a self-adhesive sticker on the back, and the label strip includes a base paper and multiple labels 200 intermittently pasted on the base paper. The printed label 200 is wrapped around the outer wall of the pipe 100 and the end of the label is folded and fixed, so that it is not easy to fall off, be incomplete, or be damaged. The label information to be printed may include diverse information such as characters, barcodes, and QR codes. The information is comprehensive and easy to read, and can be read even if some information is lost. In addition, the dedicated pipe labeling equipment can process in batches, automatically print and fold and paste, which is highly efficient and ensures high accuracy and good consistency.

[0086] In this article, Figure 1 The label 200 formed by folding and pasting is called a folded label. It is designed to affix a label to the rough surface of a hose. A long strip of label (with a self-adhesive back) is designed to wrap around the back of the two ends of the hose body and stick to each other to form a stable adhesive surface, thus forming a kind of pasting method and structure. This form of labeling innovatively uses a folded labeling method to increase the adhesion of the label to the hose and the readability of the information, thereby improving the service life of the label. It should be noted that the pipe fitting 100 in this embodiment takes a hydraulic hose as an example, but this application is not limited to this. Other plastic pipes, steel pipes, etc. can also be used.

[0087] like Figure 2 、 Figure 3 As shown, in a specific embodiment, the pipe labeling device includes:

[0088] A label reel 1, on which a label tape is wound to form a label roll 12;

[0089] The printer 4 is used to print label information on the label 200 of the label tape conveyed by the label reel 1;

[0090] The pipe fitting clamping and positioning device 5 is used to position and clamp the pipe fitting 100 to be labeled; and

[0091] The labeling device 6 is used to transfer the printed labels and stick them on the pipe.

[0092] The label tape is composed of a backing paper and a series of non-continuous self-adhesive labels affixed to the backing paper. The label roll 12 formed by the wound label tape is a non-continuous label material roll. In the present application, the label roll 12 in the label reel 1 is transferred to the printer 4. After the label information is printed, the printed label is moved by the labeling device 6 to the pipe 100 positioned and clamped on the pipe clamping and positioning device 5. The label is folded in half and affixed to form a folded label that is firmly affixed to the pipe. This pipe labeling equipment can integrate various functional components and automatically complete labeling. Compared with manual labeling methods, this greatly improves labeling efficiency and diversifies the label information.

[0093] To achieve automated control, the pipe labeling equipment includes a labeling controller and is configured to:

[0094] Receive label information to be printed;

[0095] driving the label reel 1 to rotate so as to introduce the label tape into the printer 4;

[0096] Control printer 4 to print label information onto label 200;

[0097] According to the product specification information of the pipe 100, the pipe clamping and positioning device 5 is driven to position the pipe 100 at the position to be labeled;

[0098] The labeling device 6 is controlled to transfer the printed label 200 and affix the label 200 to the position to be labeled on the pipe 100 .

[0099] The labeling controller is used to control the actions and timing of various functional components. After the pipe 100 is transferred to the pipe clamping and positioning device 5 manually, on an assembly line, or by an automated guided vehicle (AGV), the pipe clamping and positioning device 5 detects or reads product specifications to determine the position of the label to be applied on the pipe, thereby clamping and positioning the pipe accordingly. Simultaneously, after the printer 4 prints the label information onto the label 200, the labeling device 6 transfers the printed label 200 and affixes it to the position on the pipe 100 to be applied, completing the label printing and folding operations.

[0100] In the present embodiment, as an example, in the specific operation, as shown in Figure 8 the material SAP code information, material description information, material unique identity certificate and product specification information, etc. can be received from the industrial computer first, and these received information can be processed by the labeling system (i.e. the labeling controller) and formed into specific label information, which can include, for example, label format, two-dimensional code integrated information, required label specification information, etc., and then the required label information to be printed is transmitted to the printer 4 to be printed into a specific label or transmitted to the related device function part of the labeling device. Finally, after the labeling is completed, the product completion work time and product labeling completion information can also be fed back to the industrial computer for further time sequence control, fault evaluation, etc. It should be understood by those skilled in the art that the labeling controller can easily convert the transmission information of the industrial computer into specific label information through program design, and this conversion process is well known to those skilled in the art and can be set according to specific circumstances, which will not be described here. In this way, based on the pipe labeling device, the transmission of product information is realized, and the labeling information of various specifications of products is transmitted to the control system, and through the labeling device and the pipe clamping and positioning device, the device and the label information are synchronized. The use of automatic labeling instead of traditional manual labeling improves efficiency and labeling accuracy and reduces labor intensity. Further, as will be described below, through the design of the pipe clamping and positioning device and the special design of the labeling device, it can also be applicable to various types of products, improving the adaptability of the device.

[0101] Referring to Figures 4a to 7 , the constitution of each functional part of the pipe labeling device of the present embodiment will be described below.

[0102] The labels 200 in the label roll 12 are pasted on the base paper to form a label tape, and the label tape is rolled to form the label roll 12, which is installed on the label roll 1.

[0103] As shown in Figure 4a , Figure 4b In the present embodiment, the printer 4 includes a carbon tape 41, a print head 43, a pressure roller 45 and a printer controller 46, the printer controller 46 is configured to receive the label information to be printed and control the pressure roller 45 to pull the label tape and the carbon tape 41 and print the label information at the print head 43.

[0104] In order to realize the separation of the label 200 from the label tape, a scraper 44 is also provided in the printer in the present embodiment, and the pulled label tape passes through the scraper 44 to separate the label and the base paper. Referring to Figure 4a , the separated base paper is recycled by the label base paper recycling roll 2 and forms the base paper roll 21. Of course, the separation of the label and the base paper is not limited to the scraper method, and any other feasible method can also be used, which will not be described here.

[0105] Specifically, the label tape is pulled by the pinch roller 45 inside the printer 4, guided through the printer 4 by multiple rollers, printed with information at the print head 43, separated from the backing paper after passing the printer blade 44, and the backing paper is rolled back to the label backing paper recycling reel 2 outside the printer 4, and rolled into the backing paper reel 21. During printing, the carbon tape 41 is pulled by the pinch roller 45, synchronously passes through the print head 43 with the label tape and releases carbon powder, and the used carbon tape 41 is rolled back on the carbon tape recycling reel 42 by the rollers. The printing process parameters are set by the printer controller 46, which can be connected to the labeling controller, external industrial computer, etc. for information transmission.

[0106] As shown in Figure 4b , Figure 5 In the embodiment, the pipe fitting clamping and positioning device 5 can include:

[0107] The pipe fitting positioning mechanism 52 includes a pipe fitting labeling positioning plate 521 capable of moving in a first direction, and the pipe end of the pipe fitting 100 placed in the first direction is positioned against the pipe fitting labeling positioning plate 521.

[0108] The pipe fitting clamping mechanism 51 includes an arc-shaped clamping plate set 511 arranged in the first direction away from the pipe fitting labeling positioning plate 52, and the arc-shaped clamping plate set 511 includes two side arc-shaped clamping plates capable of moving closer to or away from each other in a second direction perpendicular to the first direction.

[0109] In Figure 4b , it is obvious that the first direction is perpendicular to the paper surface, and the second direction is the horizontal direction of the paper surface. In Figure 5 , it is obvious that the first direction is the vertical direction of the paper surface, and the second direction is the horizontal direction of the paper surface.

[0110] Whether the hydraulic rubber hose assembly is transported manually or by a pipeline or by an AGV trolley, it is first positioned by the pipe fitting positioning mechanism 52, then clamped by the pipe fitting clamping mechanism 51, and finally labeled by the labeling device 6. Referring to Figure 5 , the hydraulic rubber hose assembly (not shown) is placed vertically, and the upper end of the rubber hose abuts against the pipe fitting labeling positioning plate 521. Since the positioning plate can move in the first direction (i.e. the vertical direction in the figure), the position of the pipe fitting in the first direction can also be adjusted for different specifications of the pipe fitting 100, so that the labeling position of the rubber hose of different specifications can be moved to the fixed and set labeling position. The two arc-shaped clamping plates 511 can horizontally hold the rubber hose, so they can also be suitable for clamping pipe fittings of different specifications. Therefore, the pipe fitting clamping and positioning device 5 is suitable for positioning and clamping pipe fittings of different specifications, and has good versatility and flexibility.

[0111] In the first direction, an interval labeling area is formed between the tube positioning mechanism 52 and the tube clamping mechanism 51. The position of the tube 100 to be labeled is located in the interval labeling area. The interval labeling area extends along the second direction to form a label transfer belt. The labeling device 6 can transfer the printed label 200 along the label transfer belt toward the interval labeling area. Figure 5 The interval labeling area is the central area of ​​the moving overlapping part of the pipe clamping and positioning device 5 and the labeling device 6, that is, Figure 5 The current position area of ​​the left labeling plate 61 in.

[0112] Specifically, the arc-shaped clamping plate group 511 is two arc-shaped clamping plates, which are installed on the clamping and positioning device guide rail 513 through the clamping and positioning device slider 512, and the clamping and positioning device guide rail 513 is fixed on the clamping and positioning device base 53.

[0113] See also Figure 5 The pipe labeling positioning plate 521 is installed in the guide rails on both sides of the platform surface of the pipe positioning mechanism 52 through the slider guide rail device 522. A long groove can be opened in the middle of the platform surface. The slider guide rail device 522 may include a screw arranged along the long groove and a slider that moves helically along the screw, or it may include a guide rod arranged along the long groove and a slider that slides along the guide rod. In short, under the drive of the motor, the slider of the slider guide rail device 522 can drive the pipe labeling positioning plate 521 to move linearly and freely adjust. Furthermore, the long groove opened in the middle of the platform surface can be marked with a distance scale. In this way, the position of the pipe labeling positioning plate 521 can be electrically adjusted by the labeling controller. It is well known to those skilled in the art that this kind of electrically driven and movable linear moving mechanism has various structural forms, which are only given as examples here and are not explained in detail one by one.

[0114] Therefore, the labeling controller can be further configured as follows:

[0115] Identifying product specification information of the pipe fitting through the label information to be printed;

[0116] Determine the position of the pipe 100 to be labeled according to the product specification information;

[0117] Control the pipe positioning mechanism 52 to stop the pipe labeling positioning plate 521 at a set position, so that when the pipe end of the pipe 100 abuts and is positioned on the pipe labeling positioning plate 521, the position of the pipe 100 to be labeled is located in the center of the interval labeling area;

[0118] The pipe clamping mechanism 51 is controlled to drive the arc-shaped clamping plate group 511 to clamp the pipe 100 .

[0119] In this way, the pipe fittings can be automatically identified, positioned and clamped according to the transmitted and read product specification information. Figure 8As shown, the information is directly transmitted from the industrial computer to the labeling controller, or, as described above, the product specification information can be incorporated into the label information so that it can be identified when needed.

[0120] See also Figure 4b 、 Figure 5 The labeling device 6 includes a first labeling plate 61 and a second labeling plate 62 arranged at intervals along the label transfer direction. The surfaces of the first labeling plate 61 and the second labeling plate 62 are both provided with suction holes for adsorbing printed labels. Figure 4b The label transfer direction is the second direction, that is, the horizontal direction of the paper.

[0121] In terms of functional components, the labeling device 6 may include:

[0122] The labeling plate transfer mechanism is used to drive the first labeling plate 61 and the second labeling plate 62 to move back and forth between the label receiving position and the labeling position, and the moving distance is controllable.

[0123] In this embodiment, as an example, the labeling plate transfer mechanism may include a labeling plate translation mechanism and a labeling plate lifting mechanism, the labeling plate translation mechanism is used to drive the first labeling plate 61 and the second labeling plate 62 to translate, and the labeling plate lifting mechanism is used to drive the first labeling plate 61 and the second labeling plate 62 to lift vertically.

[0124] Obviously, along the label transfer direction, the labeling plate translation mechanism can reciprocate between the label receiving position located directly below the scraper 44 and the labeling position located directly below the position to be labeled, thereby reciprocating the label 200. The labeling plate lifting mechanism is used to suck and receive the label 200 at a high position, move down to the bottom of the tube 100 at the labeling position, and then stick the label 200 on the tube wall of the tube 100 from the bottom upwards, and then fold the two ends of the label in half and stick it.

[0125] Specifically, the vertical motion mechanism 63 is arranged on one side of the labeling device 6, and the left and right labeling plates are installed on the screw 65 and the labeling device guide rail 68 through the labeling device slider 64. The screw 65 and the labeling device guide rail 68 are fixed to the horizontal motion mechanism 66 and fixed to the labeling device base 67.

[0126] The labeling device 6 further includes a labeling plate pushing mechanism, which is used to drive the first labeling plate 61 and the second labeling plate 62 to wrap around the outer peripheral wall of the tube, and drive the ends of the first labeling plate 61 and the second labeling plate 62 to fit together to achieve folding and pasting the two ends of the label. It is well known to those skilled in the art that such a labeling plate pushing mechanism can be an independently driven connecting rod mechanism, such as a four-bar connecting rod mechanism, or a pivoting driving mechanism to drive the two labeling plates to pivot from a horizontally expanded state to a vertically closed state. Since the specific structural type and composition of the labeling plate pushing mechanism used to drive the labeling plates to achieve wrapping the label around the tube and folding and pasting is not the focus of this application, it will not be described in detail.

[0127] Based on the structure of this labeling device 6, the labeling controller can be further configured as follows:

[0128] Control the labeling plate transfer mechanism to drive the first labeling plate 61 and the second labeling plate 62 to move to the label receiving position so as to be close to the printer 4 to absorb the printed label 200;

[0129] Control the labeling plate transfer mechanism to drive the first labeling plate 61 and the second labeling plate 62 to move to the labeling position so as to approach the position of the pipe 100 to be labeled from below;

[0130] The labeling plate pushing mechanism of the labeling device 6 is controlled to drive the first labeling plate 61 and the second labeling plate 62 to close, and the label is folded in half and pasted on the position to be labeled on the pipe.

[0131] In this way, the labeling controller can control the labeling device 6 to automatically complete the label folding and pasting operation. Furthermore, the labeling controller can be further configured to control the labeling plate pushing mechanism to drive the first labeling plate 61 and the second labeling plate 62 to close again, smoothing the gap at the end of the folded label, thereby firmly pasting the label and preventing the label from easily falling off later.

[0132] See also Figure 2 、 Figure 3 The pipe labeling system also includes a base frame 3, which assembles the various functional components. The pipe clamping and positioning device 5 and the labeling device 6 are spaced apart at the base frame 3's bottom 31. The printer 4 is located above the labeling device 6. The label reel 1 is mounted on top of the base frame 3 and connected to the printer 4 via the label tape.

[0133] Specifically, the label reel 1 is fixed above the base frame 3, the label backing paper recovery reel 2 is connected to the bearing of the label reel 1, the printer 4 is fixed inside the base frame 3, the pipe clamping and positioning device 5 is fixed to the bottom 31 of the base frame through the clamping and positioning device base 53, and the labeling device 6 is fixed to the bottom 31 of the base frame through the labeling device base 67.

[0134] See alsoFigure 8 By inputting the information to be printed (various specifications and quantities) into the external industrial computer, it can be automatically entered into the labeling system. After the labeling controller receives the start printing command, it pushes the printing information to the flash memory of the printer 4 in the pipe labeling equipment in the specified order. At the same time, the clamping roller 45 is started, driving the label roll 12 and the carbon ribbon 41 to pass to the print head position at the same time. When passing through the print head 43, the printer reads the printing information transmitted by the industrial computer, and attaches the toner on the carbon ribbon 41 to the label 200 according to the content of the information, and continues to move the label roll 12 and the carbon ribbon 41 forward.

[0135] At the initial position of the labeling device 6, the left labeling plate 61 is close to the printer scraper 44. When the printer controller 46 receives the print command, the left labeling plate 61 and the right labeling plate 62 start suction. The label roll 12 continues to move along the roller direction until it reaches the position of the printer scraper 44. Due to the inherent rigidity of the label 200, the label 200 is separated from the base paper. The base paper is guided along the roller and collected on the label base paper recovery reel 2. The label 200 leaves the scraper 44 and contacts the left labeling plate 61 and the right labeling plate 62 and is adsorbed. Synchronously, the slider 64 of the labeling device moves to the left driven by the horizontal motion mechanism 66 at the same speed as the movement speed of the label roll 12. Until the center of the labeling device 6 coincides with the center of the tube clamping mechanism 51.

[0136] The labeling controller reads the desired labeling location based on the product information contained in the labeling content and simultaneously controls the pipe labeling positioning plate 521 to adjust to the precise position. The hose product is placed on the pipe clamping mechanism 51, keeping the hose end face flush with the pipe labeling positioning plate 521. Activating the labeling switch tightens the pipe clamping mechanism 51, and the vertical motion mechanism 63 drives the labeling plates downward. The labeling plate push mechanism closes the left and right labeling plates 61 and 62, applying the label 200 to the hose in a folded position. After the labeling plates are closed and clamped, the push mechanism moves up and down once more to level the gap at the end of the fold.

[0137] After a single labeling cycle is complete, the vertical motion mechanism 63 drives the labeling plates upward, unfolding the left and right labeling plates 61 and 62, while simultaneously canceling the suction function. The tube clamping mechanism 51 opens, removing the hose. The horizontal motion mechanism 66 then drives the labeling device slider 64 rightward along the labeling device guide rail 68, moving from its initial position to the position where the left labeling plate 61 is adjacent to the printer's scraper 44. The tube labeling device then transmits print information to the industrial computer and prepares for the next labeling cycle.

[0138] In another embodiment, the labeling controller may be configured to:

[0139] Receive label information to be printed;

[0140] driving the label reel 1 to rotate so as to introduce the label tape into the printer 4;

[0141] Control printer 4 to print label information onto label 200;

[0142] Drive the pipe clamping and positioning device 5 to fix and clamp the pipe 100;

[0143] Determine the size information of the corresponding labeling position on the pipe fitting 100 according to the product specification information of the pipe fitting 100;

[0144] According to the size information of the labeling position, the labeling device 6 is driven to transfer the printed label 200 and stick the label 200 onto the pipe 100 .

[0145] In this embodiment, the control process can also be seen in Figure 8 Among them, the control logic of the labeling controller to the printer 4 is the same as Figures 2 to 7 The same is true in the embodiment shown.

[0146] The difference is, Figures 2 to 7 In the illustrated embodiment, the pipe clamping and positioning device 5 has the function of accurately positioning the position of the pipe 100 to be labeled, that is, by accurately adjusting the stop position of the pipe labeling positioning plate 521 for pipes of different specifications, the position of the pipes 100 to be labeled of different specifications are all located in the center of the spaced labeling area, and then the labeling device 6 can be simply moved horizontally to below the center of the spaced labeling area to achieve accurate labeling position.

[0147] In this embodiment, the pipe clamping and positioning device 5 is only used for conventional fixed clamping of the pipe 100. In other words, the pipe labeling positioning plate 521 can be fixed. As a result, for pipes 100 of different specifications, after being clamped by the pipe labeling positioning plate 521, the positions to be labeled are inevitably scattered, rather than being focused in the center of the interval labeling area. Therefore, precise control of the labeling device 6 is required to track the positions to be labeled for each pipe 100 of different specifications in order to achieve precise labeling positions. Therefore, in this embodiment, the labeling device 6 can be equipped with three-dimensional track movement capabilities, or directly use a robot whose spatial position can be precisely adjusted and controlled to enable flexible tracking of labeling positions.

[0148] It should be noted that the pipe labeling equipment of the present application is not limited to the use of pneumatic clamping devices. It can also use fixed-size U-shaped or V-shaped molds for replacement without affecting the function of the overall equipment. The pipe labeling equipment of the present application can also be integrated with other equipment, including but not limited to blanking machines, sorting equipment, etc. to form a combined device. In the pipe labeling equipment of the present application, the pipe labeling positioning plate 521 can be adjusted by manual nut adjustment, which does not affect the overall function of the equipment during use.

[0149] In summary, the pipe labeling equipment of this application realizes informatization, such as Figure 8 As shown, by inputting the labeling content to be printed into the labeling controller via an industrial computer, it is possible to transmit information about a variety of products in varying quantities. Furthermore, the labeling controller can identify the product specifications to be labeled, transmit information signals to various functional components, and automatically control the position of the pipe labeling positioning plate, allowing hoses of different specifications to select the appropriate labeling position. Simultaneously, according to the planned input label content, sequential processing ensures a one-to-one correspondence between the labeling information and the product, reducing search time and the probability of incorrect labeling. The pipe labeling equipment of this application also offers flexibility. The pipe clamping and positioning device 5 can adapt to different hose specifications, meeting flexible production requirements and improving the equipment's product coverage. By adjusting the gap between the left labeling plate 61 and the right labeling plate 62, labels of various specifications can be printed and applied. Furthermore, the system offers versatility, using self-adhesive labels as information carriers to print characters, barcodes, and QR codes. The labeling control program located in the industrial computer enables printing with a variety of templates, meeting diverse product labeling needs. The label appearance and marking quality are better. Self-adhesive labels are used as information carriers for marking, and the product identity information is easy to visually read and scanned. The folding and pasting method increases the adhesion of the label on the product, ensuring that the label will not fall off under various working conditions, thereby improving the product quality traceability capability.

[0150] The pipe labeling equipment of this application greatly improves efficiency. The equipment completes most of the work, and only manual uploading of print content and loading and unloading of materials are required. Compared with the manual label laminating process, the efficiency can be increased by more than 50%, and the labor intensity is low, and the laminating effect is good.
