Description

Technical Field

[0001] This invention relates to the field of printing and labeling technology, and in particular to an intelligent instant printing and labeling system. Background Technology

[0002] The demand for instant printing and labeling includes both weighing-based printing and labeling and real-time communication printing and labeling. Common characteristics of this industry demand include: instant printing and labeling, meaning the printed label must be the one immediately applied; applications requiring high label utilization (i.e., no label waste); and the object to be labeled having a certain flatness for easy automatic labeling. Specifically, the concept of instant printing and labeling is: the label being printed is the label that will be automatically peeled off and applied immediately.

[0003] The principle of a labeling machine is as follows:

[0004] An automatic labeling machine is a device that affixes rolls of paper or foil labels to specified packaging containers or products. The labels have adhesive backing and are arranged regularly on a glossy backing paper; the labeling machine's peeling mechanism automatically removes them. Labeling can perform various operations, including flat labeling, single-sided or multi-sided labeling of packaging, cylindrical labeling, partial or full coverage of cylindrical surfaces, and labeling of recessed and corner areas.

[0005] There are many types of automatic labeling machines on the market, with varying functions, but their basic principles are similar. The vast majority of automatic labeling machines use adhesives to affix paper or metal foil labels to designated packaging containers. In summary, the working characteristics of automatic labeling machines currently on the market are:

[0006] 1. Constant-speed labeling. Although the label peeling speed of an automatic labeling machine can be adjusted according to production conditions, in actual applications, it is always labeled at a fixed speed, meaning that the label peeling speed is constant during the labeling process.

[0007] 2. There are specific requirements for the object to which the label is to be applied. For example, the object may be a flat or regularly curved surface, such as a bucket, cardboard box, plastic box, or bottle. These requirements ensure that the label adheres firmly and smoothly to the surface.

[0008] The working principle of existing instant printing and labeling equipment on the market is as follows: (Refer to...) Figure 1 It mainly consists of three parts: the labeling machine body, the printing engine, and the label suction and labeling mechanism.

[0009] The main body of the labeling machine primarily functions to load and recycle labels. Its power system is flexible, providing power for label recycling while simultaneously maintaining a tight grip on the label paper relative to the printing engine, thus providing power for label peeling.

[0010] Print engine, a thermal transfer or thermal printer specially designed for labeling system by modifying a barcode printer, is provided with a label peeling plate at the outlet of the label to realize the functions of printing and label peeling. The print engine can only print labels in a continuous state, i.e. the labels must be printed in a moving state. In addition, the print head of the print engine must always press the label whether it is printing or not, and cannot be lifted. Therefore, the running of the ribbon and the label of the print engine is completely synchronized, which makes the print engine waste a lot of ribbon (thermal transfer printer consumables). For example, if the length of a single label is 100 mm and the actual printing length is 50 mm, the actual consumption of the ribbon is also 100 mm. For the ribbon, the extra 50 mm is wasted.

[0011] Label suction and labeling mechanism, composed of a label suction head and a labeling mechanism. The label suction plate of the label suction head has many small holes for circulating negative pressure air to provide suction force to suck the label. The power source comes from a vacuum generator or other negative pressure generating device. The labeling mechanism is generally a blowing labeling or a pneumatic push rod mechanism to push the label suction head and the label to the surface of the object to be labeled.

[0012] Workflow: ready to label, ready to work. In automatic mode, start the print-and-label device, the print engine will automatically print a label and peel it off to the bottom of the label suction head, the label suction head sucks the label and holds it; when the object to be labeled reaches the designated position, the labeling mechanism pushes the label suction head and the label above to stick to the surface of the object to be labeled; after labeling, the label suction head and the labeling mechanism return to their original positions, at which time the print engine reprints a label and peels it off to be sucked and held by the label suction head. The above cycle is repeated.

[0013] Problems of existing instant printing and labeling:

[0014] 1. Affected by the working principle of the print engine, i.e. the label must be printed in a running state, the labeling frequency is obviously small, which is not suitable for high-frequency application scenarios.

[0015] 2. Affected by the working principle of the print engine, i.e. the print head presses the label all the time, the consumables of the printer, i.e. the ribbon, will be wasted.

[0016] 3. Affected by the working principle of the print engine, i.e. the length of the ribbon installed in the engine is within 300 meters, the ribbon needs to be replaced frequently in the actual production process, which is troublesome and affects the production efficiency.

[0017] 4. The principle of label suction is adopted, which has the risk of label falling.

[0018] 5. The labeling principle employing suction and push significantly affects the labeling frequency and linear speed. This type of instant labeling equipment is only suitable for applications with both low labeling frequency and low linear speed.

[0019] 6. It uses a labeling principle of pushing or blowing labels, which results in low labeling accuracy.

[0020] The existing problems with instant label printing can be summarized as follows: 1. Low work efficiency, with a stable operating frequency of about 30 times / minute; 2. The printing engine wastes ribbon; 3. The printing engine can only install 300-meter-long ribbons, resulting in frequent replacements and high labor costs; 4. The labeling process is unstable, with a risk of label falling off; 5. The labeling position is inaccurate. Summary of the Invention

The main board is also equipped with a label transition roller group for guiding the rotation of the label.

[0024] The label placement mechanism is used to place the label roll; the elastic transition roller mechanism is used to maintain the tension of the label and release the label roll evenly; the label pressing mechanism applies resistance to the label to keep it taut; the bidirectional label drive mechanism provides power for the forward and reverse movement of the label; the coding mechanism prints the marking content on the label; the label peeling and printing mechanism peels off the printed label and pastes it onto the packaging film; and the label backing paper recycling mechanism recycles the label backing paper after peeling.

[0030] The application can be further configured in a preferred example that the label bidirectional driving mechanism comprises a forward driving mechanism, a reverse driving mechanism, a support column, an outer support plate, and a synchronization mechanism, the outer support plate is detachably fixed on the main board through the support column, the forward driving mechanism and the reverse driving mechanism are installed between the outer support plate and the main board to provide power for the forward and reverse operation of the label, and the synchronization mechanism is used to drive the forward driving mechanism and the reverse driving mechanism to synchronously operate.

[0031] The application can be further configured in a preferred example that the code printing mechanism is a hot transfer code printing machine, and the hot transfer code printing machine is installed on the main board.

[0032] The application can be further configured in a preferred example that the label peeling and printing mechanism comprises a printing base plate, a silica gel pad, a drag reduction roller, and a label peeling plate, the printing base plate is detachably fixed on the main board and located below the code printing mechanism, the silica gel pad is fixed on the printing base plate, the label peeling plate is fixed on the inclined surface at one end of the printing base plate, and the drag reduction roller is rotationally arranged between the silica gel pad and the label peeling plate.

[0036] In summary, the intelligent instant printing and labeling system has at least one of the following beneficial technical effects:

The intelligent instant printing and labeling system uses a thermal transfer printer to print when the label stops, and the speed of the label running and the speed of printing can be set respectively and do not affect each other. For example, in some high-demand situations, the color band used is of a very high level, and the printing speed is very slow. After the label is printed by the intelligent instant printing and labeling system, the forward driving mechanism can drive the label to peel off and label at a normal speed, that is, the labeling speed is not affected by the slow printing speed, which to some extent improves the instant printing and labeling frequency. The intelligent instant printing and labeling system uses a thermal transfer printer, and the longest color band installed can support 1200 meters, which greatly reduces the time for stopping and replacing the color band and improves the production efficiency.

[0038] 2. The intelligent instant printing and labeling system adopts a label forward and reverse driving mode, the forward driving is used to normally drive the label and peel off, and the reverse driving pulls the label at the front of the peeling plate back to the printing range of the thermal transfer printing code printer, so as to ensure that the printed label is the label to be labeled immediately.

[0039] 3. The intelligent instant printing labeling system adopts the most stable scraping and labeling method. During the running process, the label passes through the label stripping plate, the base paper continues to be pulled away, and the label continues to run forward due to its hardness, thereby being stripped from the label base paper and finally adhering to the object to be labeled.

[0050] Embodiment one:

[0051] Referring to Figure 2 The present application discloses an intelligent instant printing and labeling system, comprising a host board 1, a label placing mechanism 2, an elastic transition roller mechanism 3, a label pressing mechanism 4, a label bidirectional driving mechanism 5, a code printing mechanism 6, a label peeling and printing mechanism 7 and a label backing paper recycling mechanism 8 are installed on the host board 1, and a label transition roller group for providing guidance for the turning of the label is installed on the host board 1;

[0052] Referring to Figure 3 The label placing mechanism 2 is used for placing a label roll, the elastic transition roller mechanism 3 is used for keeping the label tension and uniformly releasing the label from the label roll, the label pressing mechanism 4 keeps the label straight by applying resistance to the label, the label bidirectional driving mechanism 5 provides power for the forward and reverse running of the label, the code printing mechanism 6 is used for printing identification content on the label, the label peeling and printing mechanism 7 is used for peeling the printed label and pasting it on the packaging film, and the label backing paper recycling mechanism 8 is used for recycling the label backing paper after label peeling.

[0053] Referring to Figure 2The host plate 1 is provided with a fixing mechanism 9, which is generally a three-rod adjusting mechanism and serves to adjust and fix.

[0054] With reference to Figure 3 The label transition roller set comprises a first label transition roller 10, a second label transition roller 11, a third label transition roller 12, a fourth label transition roller 13 and a fifth label transition roller 14.

[0055] The label paper led out by the label feeding mechanism 2 passes through the first label transition roller 10, the elastic transition roller mechanism 3, the second label transition roller 11, the label pressing mechanism 4, the label bidirectional driving mechanism 5, the third label transition roller 12, the fourth label transition roller 13, the label peeling and printing mechanism 7 and the fifth label transition roller 14 in sequence and is wound in the label base paper recycling mechanism 8, and the coding mechanism 6 prints the identification content on the label between the third label transition roller 12 and the fourth label transition roller 13.

[0056] With reference to Figure 3 The label feeding mechanism 2 comprises a label disc 21, a label outer baffle 22, a label cylinder 23, a label cylinder center shaft 24 and a label cylinder friction wheel. The label cylinder 23 is installed on the host plate 1 through the label cylinder center shaft 24, the label disc 21 and the label outer baffle 22 are arranged on the two sides of the label cylinder 23 respectively, and the label cylinder friction wheel is installed on the side of the label disc 21 away from the label cylinder 23.

[0057] With reference to Figure 3 The elastic transition roller mechanism 3 comprises an elastic rod 31, a friction rubber band, a spring, a transition roller 32 and a transition roller center shaft 33. The transition roller 32 is installed on the elastic rod 31 through the transition roller center shaft 33, and the spring and the friction rubber band are arranged on the elastic rod 31. The main function of the elastic transition roller mechanism 3 is to keep a certain tension of the label and uniformly release the label from the label cylinder. The specific implementation manner is as follows: when the label runs, the elastic transition roller 32 is pressed down, at this time, the pressure between the friction rubber band fixed at the tail of the elastic rod 31 and the label cylinder friction wheel is reduced, so that the label cylinder 23 continues to release the label under the action of the label tension; when the label stops, the elastic rod 31 is lifted up under the tension of the spring, at this time, the pressure between the friction rubber band fixed at the tail of the elastic rod 31 and the label cylinder 23 gradually increases until the label cylinder 23 stops rotating, at this time, the label stops releasing, the elastic rod 31 is in the highest position, and the tension of the label fluctuates in a very small range during the whole process, so that the control of the label tension is realized.

[0058] With reference to Figure 3The label pressing mechanism 4 comprises a label pressing plate 41, a label pressing plate mounting block 42, a label pressing plate mounting block rotating shaft 43, and a pressure bearing shaft 44. The label pressing plate 41 is fixed on the label pressing plate mounting block 42, the label pressing plate mounting block 42 is arranged on the label pressing plate mounting block rotating shaft 43, the label pressing plate mounting block rotating shaft 43 is rotationally arranged on the main machine plate 1, the pressure bearing shaft 44 is arranged on one side of the label pressing plate 41, and the label passes between the gap between the pressure bearing shaft 44 and the label pressing plate 41. The main function of the label pressing mechanism 4 is to provide a certain resistance to the label, so that the label at this position remains in a straight state.

[0059] With reference to Figure 3 The label bidirectional driving mechanism 5 comprises a forward driving mechanism 51, a reverse driving mechanism 52, a support column 53, an outer support plate 54, and a synchronization mechanism. The outer support plate 54 is detachably fixed on the main machine plate 1 through the support column 53. The forward driving mechanism 51 and the reverse driving mechanism 52 are installed between the outer support plate 54 and the main machine plate 1 to provide power for the forward and reverse movement of the label. The synchronization mechanism is used to drive the forward driving mechanism 51 and the reverse driving mechanism 52 to move synchronously.

[0060] With reference to Figure 4 The forward driving mechanism 51 comprises a first driving active soft shaft 511, a counterclockwise one-way bearing, a first driving passive knurled hard shaft 512, and a first locking block. The first driving active soft shaft 511 and the first driving passive knurled hard shaft 512 are pressed together in the running state to transmit power to the label and prevent slipping.

[0061] With reference to Figure 4 The reverse driving mechanism 52 comprises a second driving active soft shaft 521, a clockwise one-way bearing, a second driving passive knurled hard shaft 522, and a second locking block. The second driving active soft shaft 521 and the second driving passive knurled hard shaft 522 are pressed together in the running state to transmit power to the label and prevent slipping.

[0062] The synchronization mechanism comprises a first synchronization pulley 55, a second synchronization pulley 56, a third synchronization pulley 57, and a synchronization belt 58. The first synchronization pulley 55 is coaxially fixed on the first driving active soft shaft 511. The second synchronization pulley 56 is coaxially fixed on the second driving active soft shaft 521. The third synchronization pulley 57 is rotationally arranged on the main machine plate 1. The synchronization belt 58 is tightly sleeved outside the first synchronization pulley 55, the second synchronization pulley 56, and the third synchronization pulley 57.

[0063] In the embodiment, the coding mechanism 6 is a thermal transfer overprinter, which is installed on the main plate 1. The thermal transfer overprinter is a standard integrated product, and its English name is Thermal Transfer Overprinter, abbreviated as TTO. It mainly consists of two parts: a printing body and a controller. In the past ten years, it has been widely used in the soft packaging industry, especially because of its small size, flexible installation, high stability, large printing area, high resolution (300 DPI), and rich printing content (such as printing numbers, letters, graphics, bar codes, two-dimensional codes, tables, etc.), it has been widely recognized in the application demand of customized identification content.

[0064] Referring to Figure 5 , the label stripping printing mechanism 7 includes a printing base plate 71, a silica gel pad 72, a drag-reducing roller 73, and a label stripping plate 74. The printing base plate 71 is detachably fixed on the main plate 1 and located below the coding mechanism 6. The silica gel pad 72 is fixed on the printing base plate 71. The label stripping plate 74 is fixed on the inclined surface at one end of the printing base plate 71. The drag-reducing roller 73 is rotatably arranged between the silica gel pad and the label stripping plate 74.

[0065] Referring to Figure 6 , when the label runs above the silica gel pad, the coding mechanism 6 prints the identification content on the label. The printed label passes through the drag-reducing roller 73, and the label stripping plate 74 moves in the opposite direction, and the label stripping is realized at the tip of the label stripping plate 74.

[0066] Referring to Figure 3 , the label bottom paper recycling mechanism 8 includes a servo motor 81, a label collecting inner baffle plate 82, a label collecting cylinder 83, a bottom paper fixing U-shaped rod, a label collecting friction wheel, and a friction belt. The servo motor 81 provides power for driving the label to run, and is transmissionally connected with the label collecting cylinder 83 through the label collecting friction wheel and the friction belt. The label collecting inner baffle plate 82 is fixed at one end of the label collecting cylinder 83, and the bottom paper fixing U-shaped rod is fixed at the other end of the label collecting cylinder 83.

[0067] The application also includes a control system and a label used-up eye 91, a label detecting eye, and a label guiding roller 93 connected with the control system. The label used-up eye 91 is installed on the main plate 1 to detect whether there is a label. When the label is used up, the eye outputs a signal to the control system to remind to replace the label. The label detecting eye is installed on one side of the coding mechanism 6 to detect the gap of the label and provide an original signal for the label to stop. The label guiding roller 93 is used to press the label tightly on the object to be pasted, which is generally a sponge roller. The control system is composed of software and hardware, and provides photoelectric and program control for the integration of the whole system and the user interface.

[0068] The working principle of the application is as follows:

[0069] The running state of the label is divided into three types: running state, ready position, and printing position.

[0070] 1. Ready state: the label is installed, after clicking the user interface "auto run", the control system of the intelligent instant printing and labeling system immediately sends instructions to the forward driving mechanism 51 and the reverse driving mechanism 52 to drive the label to the printing position of the heat transfer printing and coding machine, and sends instructions to the heat transfer printing and coding machine to immediately execute printing. After printing is completed, the forward driving mechanism 51 of the intelligent instant printing and labeling system drives the label to the ready position, and waits for the signal to peel off and label.

[0071] 2. When the detection light photoelectrically senses the signal of the arrival of the labeled object, the control system sends instructions to the forward driving mechanism 51 after a set delay time T, and the forward driving mechanism 51 drives the label to peel off and label. During this process, the reverse driving mechanism 52 is in a powerless state and does not affect the forward movement of the label.

[0072] 3. When the label detection light photoelectrically detects the label interval signal, the control system sends instructions to the forward driving mechanism 51 to immediately stop sending labels after experiencing a set header position value S1. At this time, a label has been completely peeled off and adhered to the surface of the labeled object.

[0073] 4. When the label stops, the control system immediately sends instructions to the forward driving system and the reverse driving system to drive the label to reverse a set distance S2 to reach the printing position and then stop, so that the label is located within the printing range of the heat transfer printing and coding machine. The control system immediately sends instructions to the heat transfer printing and coding machine to execute printing. During this process, the forward driving mechanism 51 and the reverse driving mechanism 52 run synchronously and in the same direction.

[0074] 5. After the control system experiences a label stop time T2 and after the heat transfer printing and coding machine finishes printing, it immediately sends instructions to the forward driving mechanism 51 to drive the printed label from the printing position to the ready position of the label, i.e., the position of the printed label is at the edge of the label peeling plate 74, waiting for the signal to peel off. During this process, the reverse driving mechanism 52 is in a powerless state and does not affect the forward movement of the label. The above processes 2-5 are repeated.

[0075] The steps for installing the label are as follows:

[0076] The label in roll form is installed on the label mounting mechanism 2, and the label is released in clockwise direction, bypasses the first label transition roller 10 in counterclockwise direction, bypasses the elastic transition roller 32 in clockwise direction, then bypasses the label pressing mechanism 4 in clockwise direction and is pressed, then passes between the second driving active soft shaft 521 and the second driving passive knurled hard shaft 522 of the reverse driving mechanism 52, bypasses the third label transition roller 12 in clockwise direction, passes through the U-shaped slot of the label inspection electric eye, then bypasses the fourth label transition roller 13 in counterclockwise direction, passes above the label stripping plate, then bypasses the label stripping plate 74, then bypasses the fifth label transition roller 14 in counterclockwise direction, then passes between the first driving active soft shaft 511 and the first driving passive knurled hard shaft 512 of the forward driving mechanism 51 in clockwise direction, then winds around the label recycling cylinder 83 of the label recycling mechanism 8 in counterclockwise direction, and the bottom paper is fixed by the bottom paper fixing U-shaped rod. In addition, the intelligent instant printing and labeling system can be additionally provided with an encoder, so that it becomes a variable-speed instant printing and labeling system, and the labeling accuracy is further improved.

[0077] The intelligent instant printing and labeling system adopts label forward and reverse driving mode, the forward driving is used for normally driving the label and stripping, and the reverse driving pulls the frontmost label at the stripping plate back to the printing range of the thermal transfer printing machine, so as to ensure that the printed label is the label to be pasted immediately. The intelligent instant printing and labeling system adopts the most stable scraping and pasting stripping and labeling method. During the running of the label, when the label passes through the label stripping plate 74, the bottom paper continues to be pulled away, and the label continues to run forward due to its hardness, so as to be stripped from the label bottom paper and finally adhered to the object to be pasted.

[0078] Further, the beneficial effects of the present application are:

[0079] 1. The intelligent instant printing and labeling system adopts a thermal transfer printer, and a special ribbon cartridge can express and replace the ribbon, so as to improve the production efficiency.

[0080] 2. The intelligent instant printing and labeling system adopts a thermal transfer printer, and the print head is pressed together with the label during printing, and the print head is lifted when the printing is completed. Therefore, the consumption of the thermal transfer printer ribbon is only related to the length of the printing content, and is irrelevant to the length of the single label. Therefore, the ribbon is not wasted.

[0081] 3. The intelligent instant printing and labeling system adopts a thermal transfer printer, and the gap between the adjacent two used traces on the ribbon is about 0.5 mm, which greatly saves the consumption of the ribbon and reduces the production cost.

[0082] 4. The intelligent instant printing and labeling system adopts the most common scraping and pasting labeling method, that is, the label is directly completed pasting while being stripped, and the label falling phenomenon will never occur, and the labeling stability is high.

[0083] 5、The intelligent instant printing labeling system adopts the traditional and most common scraping labeling method, that is, the label is directly completed labeling while peeling, the labeling efficiency is high, and the labeling frequency is improved to a certain extent.

[0084] 6、The intelligent instant printing labeling system adopts the traditional and most common scraping labeling method, that is, the label is directly completed labeling while peeling, and the labeling precision is high.

[0085] 7、The intelligent instant printing labeling system adopts the traditional and most common scraping labeling method, and an encoder can be installed in some special occasions to make it a variable-speed instant printing labeling system, further improving the labeling precision.

[0086] The implementation principle of the embodiment is: the intelligent instant printing labeling system adopts a label bidirectional driving mechanism 5, realizes the dynamic unity of the printing range of the thermal transfer printing coding machine and the position of the label, and makes the application of the thermal transfer printing coding machine in the instant labeling printing industry possible. The intelligent instant printing labeling system adopts a thermal transfer printer to print when the label stops, and the speed of the label running and the printing speed can be set respectively and do not affect each other. For example, in some high-demand occasions, the color band used is very high, and the printing speed is very slow. After the intelligent instant printing labeling system completes the printing of the label, the forward driving mechanism 51 can drive the label to peel and label at a normal speed, that is, the labeling speed is not affected by the slow printing speed, which improves the instant printing labeling frequency to a certain extent. The intelligent instant printing labeling system adopts a thermal transfer printer, and the longest color band installed supports 1200 meters, which greatly reduces the time of stopping and replacing the color band and improves the production efficiency.

[0087] The embodiments of the specific embodiment are preferred embodiments of the application, but do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
