Description

Technical Field

[0001] This utility model relates to the field of automated production equipment, and in particular to an automatic distance measuring inkjet coding device. Background Technology

[0002] Currently, in the production of chemical products, especially in the production of ton-sized and larger packaged products, there are increasingly higher requirements for production efficiency and industrial automation. During the production process, after ton-sized materials have undergone one processing step, manual intervention is usually required to ensure the smooth and stable transport of the materials to the next workstation for further processing. For example, excessive tilting angles during transport or severe bulging of the packaged products can cause problems. Due to the large size and weight of the products, manual correction is difficult and carries a certain risk of product tipping, leading to low efficiency, potential positioning errors, and material damage, which can ultimately prevent the completion of the next coding process.

[0003] As for the automation devices used in this regard, most currently employ two-sided clamping and single-sided clamping methods for fixed-position correction operations. This requires multiple sets of cylinders and multiple processed parts, which are costly, complex in structure, have low applicability, and high failure rate. During the alignment operation, the product surface is easily scratched by the mechanism's support components, and debugging is difficult. Packaged products are prone to deformation and poor size consistency. Fixed inkjet printers, on the other hand, have limited distance, resulting in unsatisfactory coding printing effects. Furthermore, the printing position is not fixed, and the inkjet head is easily damaged by collisions. Therefore, there is a need to develop an automated distance measuring coding mechanism with a simple structure and easy control. Utility Model Content

[0004] The main purpose of this invention is to provide an automatic distance measuring inkjet printing device. The device detects the presence of material through a material sensor. When the material sensor detects the material to be printed, the lead screw slide moves the inkjet printing head and the distance measuring sensor toward the material to be printed simultaneously. When the distance measuring sensor measures the material within a set range, the inkjet printing head prints the material, effectively preventing the inkjet printing head from colliding with the material.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic ranging inkjet coding device, comprising:

[0007] The cabinet has a control center inside, and material sensors for detecting the position of materials are fixedly installed on the side of the cabinet.

[0008] The inkjet printing device includes a horizontally arranged telescopic component, an inkjet print head, and a distance sensor. The telescopic component is vertically installed above the corresponding position of the material sensor. The inkjet print head is fixedly assembled at the telescopic end of the telescopic component. The distance sensor is arranged side by side with the inkjet print head and maintains synchronous displacement for real-time detection of the printing distance.

[0009] The material sensor, telescopic component, inkjet printer head, and distance sensor are all electrically connected to the control center inside the cabinet.

[0010] Furthermore, the telescopic component employs a lead screw slide.

[0011] Furthermore, a fixed plate is fixedly connected to the slide plate of the telescopic component, and the inkjet printer head and the distance sensor are both fixedly connected to the fixed plate. A detection plate is fixedly connected to one side of the slide plate, and a position sensor A and a position sensor B, which cooperate with the detection plate, are arranged along the length direction on one side of the bed of the telescopic component. Both position sensors A and B are electrically connected to the control center.

[0012] Furthermore, a warning light is installed on the top of the cabinet.

[0013] Furthermore, an operation panel is provided on one side of the cabinet.

[0014] Furthermore, casters are also provided at the bottom of the cabinet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] I. This patent uses a material sensor on the cabinet to detect the material to be printed on the conveyor belt. A telescopic component is set vertically above the material sensor, and the printing head is fixed on the telescopic end of the telescopic component. At the same time, a distance measuring sensor is set in parallel and maintains synchronous displacement to ensure the consistency of the printing head's position relative to the material to be printed during printing. The structure is simple and easy to adjust. For convenient control, a control center PLC is installed in the cabinet.

[0017] II. This patent uses a lead screw slide as the telescopic component and a stepper motor to control the movement of the telescopic end of the component, thus ensuring its stability. Furthermore, a detection plate is installed on the slide of the lead screw slide, and position sensors A and B are installed on the bed of the lead screw slide. When the detection plate on the slide moves to position sensor B, i.e., to the foremost position, if the distance detected by the distance measuring sensor is still less than the working distance of the inkjet printer head, the machine will stop working and an alarm will be triggered in the control center.

[0018] Third, alarm lights were installed above the control cabinet to make the equipment alarms more visible.

[0019] Fourth, a control panel is also installed on the cabinet for convenient and intuitive equipment debugging.

[0020] 5. To facilitate moving the cabinet, casters were installed at the bottom of the cabinet. Attached Figure Description

[0024] To facilitate understanding of this utility model, specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings, which show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.

[0025] like Figs. 1-3 As shown, an automatic ranging inkjet coding device includes:

[0026] Cabinet 10, which has a control center inside, and a material sensor 101 for detecting the position of materials is fixedly installed on the side of the cabinet 10.

[0027] The coding device 20 includes a horizontally arranged telescopic component 201, a coding print head 202, and a distance sensor 203. The telescopic component is vertically installed above the material sensor 101 at the corresponding position. The coding print head 202 is fixedly assembled at the telescopic end of the telescopic component 201. The distance sensor 203 is arranged side by side with the coding print head 202 and maintains synchronous displacement for real-time detection of the printing distance.

[0028] The material sensor 101, telescopic component 201, inkjet printer head 202, and distance sensor 203 are all electrically connected to the control center inside the cabinet 10.

[0029] Specifically, the material sensor can be OMRON, model E3Z-D62, and the distance sensor can be BOJKE, model ER2-22N.

[0030] Furthermore, the telescopic component 201 adopts a lead screw slide.

[0031] Furthermore, a fixing plate 2012 is fixedly connected to the slide plate 2011 of the telescopic component 201. The inkjet printer head 202 and the distance sensor 203 are both fixedly connected to the fixing plate 2012. A detection piece 20111 is fixedly connected to one side of the slide plate 2011. A position sensor A20131 and a position sensor B20132 are arranged along the length direction on one side of the bed 2013 of the telescopic component 201, which cooperate with the detection piece 20111. The position sensor A20131 and the position sensor B20132 are both electrically connected to the control center.

[0032] Furthermore, a warning light 102 is provided on the top of the cabinet 10.

[0033] Furthermore, an operation panel 103 is provided on one side of the cabinet 10.

[0034] Furthermore, casters 104 are also provided below the cabinet 10.

[0035] Specifically, an automatic ranging and coding device includes a cabinet 10. The upper part of the cabinet has an air intake fan, the side has a cooling fan exhaust port, and the top has a warning light 102. The operation panel 103 includes an LCD screen, a power button, a reset button, a start button, and a stop button. The cabinet 10 contains a PLC controller (in this patent, the PLC control is conventional sequential control and feedback control, which are common techniques for those skilled in the art and will not be described in detail). In actual use, pressing the power button powers on the device. After about one minute, the internal mechanism is powered on and activated. The telescopic component 201 automatically resets, the LCD screen automatically lights up to display the standby status, and the warning light 102 illuminates on the top. The indicator light 102 will remain constantly yellow, and the cooling fan will run. Pressing the start button will activate the electrical mechanism, at which point the top warning light 102 will change from yellow to green, and the LCD screen will display that the device is ready to operate. When the material sensor 101 detects a product on the conveyor, it will send an incoming material signal to the control center. The control center will then control the telescopic component 201 to operate. The distance sensor 203 and the inkjet printer head 4 at the telescopic end will move simultaneously. When the distance sensor 203 is 20 mm away from the product (the specific value depends on the setting during use), the control center will control the inkjet printer head 4 to print the code. After the printing is finished, the telescopic component 201 will reset and return to its original position to wait for the next material.

[0036] In special cases where the reverse tilt angle of the material is greater than 45 degrees, after the material sensor 101 detects the material, the sliding plate 2011 of the telescopic component 201 drives the inkjet printer head and the distance sensor 203 to move forward. When the detection plate 20111 moves to the maximum travel range, i.e., the position sensor B20132, the distance between the product and the distance sensor 203 is greater than the set value. At this time, the warning light 102 will flash continuously. At this time, the operator needs to intervene manually by pressing the electrical stop button to clear the abnormal alarm. Pressing the reset button again will cause the telescopic component 201 to automatically return to the original position and wait for the next material to be processed.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
