Description

Technical Field

[0001] The utility model relates to the technical field of inkjet code detection, in particular to an inkjet code detection device. Background Art

[0002] At present, when some manufacturers produce packaging bags, they need to spray codes on their surfaces before they leave the factory. The inkjet printer is a device that uses software control and non-contact methods to mark products. According to the consumables used by the inkjet printer, there are two types: one is the inkjet printer; the other is the non-ink inkjet printer, that is, the laser inkjet printer. At present, the inkjet printer is usually used in conjunction with a conveying mechanism. The conveying mechanism automatically conveys the items to be coded. It is combined with an automatic control system and an infrared sensor to achieve automatic coding, which can effectively improve the coding efficiency and coding quality.

[0003] However, when coding the packaging bags, since the coding equipment is fixedly installed above the conveying mechanism, that is, the position of the coding nozzle and the position of the detection probe after coding are mostly fixed, if coding is performed on different types of packaging bags, since the position of the coding is fixed, it is not convenient to adjust on site, and the existing coding device does not have the function of automatically rejecting unqualified products (unclear lines or missing coding after coding, etc.). Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a coding detection device, which can facilitate the compression and transportation of the packaging bag through a clamping mechanism arranged at the front end of the conveying mechanism, thereby ensuring that the packaging bag will not move and cause position deviation during the conveying process, effectively ensuring the accuracy of the coding, and through the adjustable alignment mechanism, the conveying position of the packaging bag on the conveying mechanism can be adjusted according to the type of different packaging bags, thereby facilitating the coding at the designated position on the packaging bag without adjusting the spray terminal, and a rejection mechanism is arranged at the end of the conveying mechanism, which can facilitate the rapid and automatic rejection of defective products, effectively ensuring the quality of the coding.

[0005] The utility model is implemented by constructing a coding detection device, including a conveying mechanism, which is arranged on a supporting frame;

[0006] The inkjet detection box is arranged on the support frame and runs through the conveying mechanism;

[0009] The rejection mechanism is movably arranged at the end of the conveying mechanism to facilitate the rejection of unqualified packaging bags.

[0010] Specifically, the clamping mechanism includes a plurality of mounting blocks, which are arranged on the frames on both sides of the conveying mechanism;

[0011] Two mounting rods are parallel and span the top of the conveying mechanism and are fixed between the mounting blocks;

[0012] Two rotating rods are arranged at the lower end of the mounting rod and are kept rotating;

[0013] A compression belt, which is tensioned between the two rotating rods to keep the bottom of the compression belt close to the conveying surface of the conveying mechanism;

[0014] Any one of the rotating rods is driven to rotate by an external driving device, and the rotation direction of the rotating rod is adapted to the conveying direction of the conveying mechanism.

[0015] Specifically, the alignment mechanism includes two adjustment plates, which are respectively arranged in parallel on both sides of the conveying mechanism and keep the top sleeved on the mounting rod for linear sliding;

[0016] Two guide blocks are mounted on opposite surfaces of the adjustment plate;

[0017] An adjusting rod, one end of which is rotatably connected to the adjusting plate, and the other end of which passes through the mounting block and is threadedly connected to the mounting block;

[0018] A guide rod, one end of which is fixed to the adjustment plate and the other end of which slides through the mounting block.

[0019] Specifically, the guide block is in the shape of a right-angle trapezoidal block, and the facing surfaces of the two guide blocks are inclined surfaces and are arranged with the small ends facing outwards.

[0020] Specifically, the rejection mechanism is a rejection plate rotatably arranged below the end of the conveying mechanism. When the rejection plate rotates to the first extreme position, the packaging bags conveyed on the conveying mechanism will be guided along the first surface of the rejection plate to the outer end. When the rejection plate rotates to the second extreme position, the packaging bags conveyed on the conveying mechanism will be guided along the second surface of the rejection plate to the bottom of the conveying mechanism.

[0021] Specifically, the rotation of the rejection plate is controlled by a transmission mechanism, and the transmission mechanism and the inkjet detection box are in communication with an external control system.

[0022] The utility model has the following beneficial effects:

[0031] The technical solution of the present invention is further specifically described below through specific embodiments in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0032] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0033] As described in the background technology, the existing inkjet coding device is usually fixedly installed above the conveying mechanism, which is not convenient for adjustment according to the conveying position of the product to be coded, nor is it convenient for adjustment of the coding position specified for different types of coding products. It also does not have an automatic rejection function, and unqualified products need to be manually rejected, which is more troublesome.

[0034] Based on the above reasons, the utility model provides a coding detection device, including a conveying mechanism 2, which is arranged on a supporting frame 1;

[0035] The inkjet detection box 3 is arranged on the support frame 1 and penetrates the conveying mechanism 2;

[0036] The pressing mechanism is arranged at the head end of the conveying mechanism 2 to facilitate the individual conveying of the packaging bags;

[0037] The alignment mechanism is movably arranged at the front end of the pressing mechanism to facilitate guiding the packaging bag for conveying and can be adjusted according to the type of packaging bag;

[0038] The rejection mechanism is movably arranged at the end of the conveying mechanism 2 to facilitate the rejection of unqualified packaging bags.

[0039] Through the above-mentioned technical features, a clamping mechanism is arranged at the front end of the conveying mechanism, which can facilitate the compression and conveying of the packaging bags, thereby ensuring that the packaging bags will not be displaced due to movement of position due to external factors during the conveying process, effectively ensuring the accuracy of the inkjet coding, and the adjustable alignment mechanism can be used to adjust the conveying position of the packaging bags on the conveying mechanism according to the types of different packaging bags, thereby ensuring that the coding is performed at the designated position on the packaging bag without adjusting the inkjet terminal, and a rejection mechanism is arranged at the end of the conveying mechanism, which can facilitate the rapid and automatic rejection of defective products, effectively ensuring the quality and efficiency of the inkjet coding.

[0040] Furthermore, a paging machine can be provided at the front end of the conveying mechanism to automatically separate stacks of plastic bags, packaging bags or cards of various specifications and convey them individually to the conveyor belt for printing by a printer or laser machine.

[0041] Specifically, the clamping mechanism includes a plurality of mounting blocks 5, which are arranged on the frames on both sides of the conveying mechanism 2;

[0042] Two mounting rods 6 are parallel and span the top of the conveying mechanism 2 and are fixed between the mounting blocks 5;

[0043] Two rotating rods 7 are arranged at the lower end of the mounting rod 6 and keep rotating;

[0044] A compression belt 8 is tensioned between two rotating rods 7 to keep the bottom of the compression belt 8 close to the conveying surface of the conveying mechanism 2;

[0045] Any one of the rotating rods 7 is driven to rotate by an external driving device, and the rotation direction of the rotating rod 7 is adapted to the conveying direction of the conveying mechanism 2 .

[0046] Through the above-mentioned technical features, a compression belt is arranged above the conveying mechanism to ensure the smooth compression and conveying of the packaging bag, ensure that the position will not be moved due to external force during the conveying process, and ensure the accuracy of coding and detection.

[0047] Furthermore, the clamping mechanism may pass through the coding detection box to ensure smooth transportation of the packaging bags during coding and detection.

[0048] Specifically, the alignment mechanism includes two adjustment plates 9, which are respectively arranged in parallel on both sides of the conveying mechanism 2 and keep the top sleeved on the mounting rod 6 for linear sliding;

[0049] Two guide blocks 10 are mounted on opposite surfaces of the adjustment plate 9;

[0050] An adjusting rod 11, one end of which is rotatably connected to the adjusting plate 9, and the other end of which passes through the mounting block 5 and is threadedly connected to the mounting block 5;

[0051] One end of the guide rod 12 is fixed to the adjustment plate 9 , and the other end slides through the mounting block 5 .

[0052] Through the above-mentioned technical features, adjusting plates and guide blocks are arranged on both sides of the conveying mechanism to facilitate the guidance of the packaging bags. The positions of the adjusting plates at both ends can be adjusted through the adjusting rods and guide rods, and then the positions of the guide blocks can be adjusted to adapt to different types of packaging bags for conveying, coding and detection.

[0053] Specifically, the guide block 10 is in the shape of a right-angled trapezoidal block, and the facing surfaces of the two guide blocks 10 are inclined surfaces with the small ends facing outwards.

[0054] Through the above technical features, setting the guide block as a right-angle trapezoidal block is convenient for installation and guiding.

[0055] By the attached Figure 5As shown, specifically, the rejection mechanism is a rejection plate 13 rotatably arranged below the end of the conveying mechanism 2. When the rejection plate 13 rotates to the first extreme position, the packaging bags conveyed on the conveying mechanism 2 will be guided along the first surface of the rejection plate 13 and conveyed to the outer end. When the rejection plate 13 rotates to the second extreme position, the packaging bags conveyed on the conveying mechanism 2 will be guided along the second surface of the rejection plate 13 and conveyed to the bottom of the conveying mechanism 2.

[0056] Furthermore, the first extreme position is the extreme position of the rejection plate rotating counterclockwise. In this position, the top end of the rejection plate is below the end of the conveying mechanism. When the packaging bag falls from the conveying mechanism, it can fall above the rejection plate and slide to the external conveying equipment under the action of inertia.

[0057] The second extreme position is the extreme position of the rejection plate rotating clockwise. At this position, the top end of the rejection plate is above and outside the end of the conveying mechanism. When the packaging bag is conveyed to the end of the conveying mechanism, it is blocked by the plate surface of the rejection plate and moves downward, causing the packaging bag to deform. At this time, the packaging bag can fall along the gap between the rejection plate and the end of the conveying mechanism.

[0058] Specifically, the rotation of the rejection plate 13 is controlled by a transmission mechanism, and the transmission mechanism and the inkjet detection box 3 are in communication with an external control system.

[0059] Furthermore, the transmission mechanism is a gear transmission mechanism 14, the driven wheel of the gear transmission mechanism 14 is installed on the rotating rod where the rejection plate 13 is located, and the driving wheel of the gear transmission mechanism 14 is installed on the driving shaft of the driving motor 15, and the driving motor 15 can be fixed on the side of the frame of the conveying mechanism 2.

[0060] Furthermore, the transmission mechanism may also be configured as other forms, such as a rack and pinion transmission mechanism, wherein a gear is provided on the rotating rod where the reject plate 13 is located, and the rack is provided on a linear telescopic mechanism (such as a cylinder, a hydraulic cylinder, etc.), and the rack is moved by the telescopic movement of the linear telescopic mechanism, thereby driving the gear and the reject plate 13 where the gear is located to rotate.

[0061] Specifically, a warning light 4 is also provided on the conveying mechanism 2, and the warning light 4 communicates with an external control system.

[0062] Specifically, the inkjet detection box 3 is provided with an inkjet gun, an infrared sensor and a detection probe, etc. The inkjet gun is arranged at the front end of the detection probe (compared with the conveying direction), the inkjet gun is arranged as an existing commonly used inkjet terminal, and the detection probe is arranged as an existing sensor probe or an optical probe, etc., which can realize the detection of whether the code after inkjet is complete and whether there is any leakage.

[0063] When the inkjet coding detection device is in use, the alignment mechanism is adjusted in advance according to the type of packaging bag. When adjusting, it is only necessary to rotate the adjusting rod 11. Since the adjusting rod 11 is threadedly connected to the mounting block 5 (for the convenience of display, the thread line is not shown in the accompanying drawings), the adjusting plate and the guide block can be driven to move along the mounting rod 6 on the conveying mechanism 2 during the rotation process. When the guide block 10 at one end is adjusted, it is adjusted according to packaging bags of different sizes, but the inkjet coding position is the same. When the guide blocks 10 at both ends are adjusted, they are adjusted according to different inkjet coding positions. The packaging bags can be of the same type or different types.

[0064] After the adjustment is completed, the packaging bags are transported individually to the conveying mechanism 2 through the paging machine, and enter the gap between the conveying mechanism 2 and the compression belt 8 under the action of the guide block 10. Since the conveying surface of the conveying mechanism 2 is driven to rotate by a driving motor (common conveyor belt type), and the compression belt 8 is also driven to rotate by an external driving motor, the packaging bag can be driven to move into the coding detection box 3. When the infrared sensor inside the coding detection box 3 scans the packaging bag, a signal will be sent to the automatic control system (such as a PLC system), and the automatic control system will control the coding gun to perform coding operation. After coding is completed, it will move to the detection probe for detection. When it is detected as an unqualified product (that is, the coding lines are unclear or missed), the automatic control system will control the transmission mechanism in the rejection mechanism to move once. After the preset time or when the detection probe does not detect the packaging bag, it means that the packaging bag has been rejected. The reverse movement of the transmission mechanism drives the rejection plate 13 to return to its original position, which is convenient for subsequent coding detection of the packaging bag.

[0065] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
