Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a single-sheet feeding device. Background Technology

[0002] In automated production equipment, the feeder is a common workpiece conveying device. Its main function is to separate stacked workpieces one by one and accurately feed them into subsequent processing steps. In order to ensure the accuracy and stability of the feeding process, existing technology usually sets up a vibration motor in the feeder mechanism to help separate multiple sheets of paper, thereby achieving the effect of single-sheet feeding.

[0003] Specifically, when the adsorption component begins to adsorb paper, the vibrating motor generates vibration, causing the excess paper stacked together to fall off through mechanical vibration, leaving only one sheet for the adsorption component to use. This method performs well when handling ordinary paper, effectively reducing the situation where multiple sheets of paper are adsorbed simultaneously. However, when handling workpieces with high surface friction or paper sticking together due to static electricity, the vibrating motor often proves insufficient. Under conditions of high friction or strong static electricity, the paper easily adheres to each other, making it difficult for multiple sheets to be separated and dropped by simple vibration. In this case, even if the vibrating motor continues to work, the adhesion between the papers exceeds the separation force generated by the vibration, ultimately resulting in multiple sheets of paper being adsorbed simultaneously, thus affecting the accuracy of feeding and production efficiency.

[0004] Therefore, a single-sheet feeding device is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this invention is to provide a single-sheet feeding device, which aims to solve the problem that existing feeding machines feed multiple sheets, affecting feeding accuracy and production efficiency.

[0006] To achieve the aforementioned objectives, this utility model proposes a single-sheet feeding device, including a platform for holding workpieces.

[0007] An adsorption component is located on one side of the stage and is used to adsorb and grip the workpiece.

[0008] A motion platform is located on the stage and at one end away from the adsorption component, and is used to drive the adsorption component to adsorb the workpiece.

[0009] The separator, installed above the stage, is used to separate the workpieces from the adsorption components, so that the adsorption components adsorb only a single workpiece.

[0010] Furthermore, the sheet separator includes a plurality of separating steel sheets, with gaps between the plurality of separating steel sheets, and the separating steel sheets are arranged in an inverted stepped shape from bottom to top.

[0011] Furthermore, the adsorption assembly includes multiple suction nozzles, all of which are located on one side near the sheet separator, with the nozzle positions corresponding to the conveying direction of the workpiece.

[0012] Furthermore, it also includes a vibrator mounted on the adsorption assembly.

[0013] Furthermore, the motion platform also includes a conveying component, a lifting component, and a support arm. The lifting component is slidably connected to the conveying component. The conveying component drives the lifting component to reciprocate along the length of the platform. The lifting component drives the adsorption component to move closer to or away from the platform. The support arm is disposed on the platform and extends along the conveying direction of the workpiece.

[0014] Furthermore, the adsorption assembly also includes a connecting rod, and the suction nozzle is connected to the lifting assembly via the connecting rod.

[0015] Furthermore, the lifting assembly is driven by a lead screw.

[0016] Furthermore, the sheet separator also includes a mounting column, which has a plurality of positioning holes, and the separating steel sheet is connected to the positioning holes.

[0017] Furthermore, positioning plates are provided on both sides of the platform in the width direction, and the positioning plates are slidably connected to the platform.

[0018] Furthermore, a sliding plate is provided on the side of the stage away from the adsorption component, and the sliding plate is bolted to the stage.

[0019] Beneficial effects:

[0020] This utility model discloses a single-sheet feeding device, including a platform, a conveying component and a lifting component mounted on the platform. The lifting component is slidably connected to the conveying component, and an adsorption component is connected to the lifting component. When the conveying component moves the lifting component to its origin, the lifting component moves towards the conveying platform, and the adsorption component adsorbs the workpiece on the conveying platform. A sheet separator is provided on the side of the platform near the adsorption component. The sheet separator separates the workpiece adsorbed by the adsorption component, so that the adsorption component only adsorbs a single sheet. By setting a sheet separator next to the adsorption component, this design can separate excess workpieces by physically moving the workpiece. The sheet separator can effectively separate multiple sheets of paper, avoiding adhesion and preventing multiple sheets of paper from sticking together due to static electricity, friction, etc. This is a common problem encountered by traditional adsorption systems, especially when processing thin or smooth workpieces, where multiple sheets of paper are more likely to be adsorbed together. Through the physical separation of the sheet separator, it can be ensured that only a single workpiece enters the next process, thereby improving the accuracy and reliability of paper feeding.

[0042] Reference Figures 1 to 6 A single-sheet feeding device according to an embodiment of the utility model includes a platform 100 for holding workpieces.

[0043] An adsorption component is disposed on one side of the stage 100 and is used to adsorb and grasp workpieces.

[0044] A motion platform is located on the stage 100 and at one end away from the adsorption component, and is used to drive the adsorption component to adsorb the workpiece.

[0045] The separator 200 is installed above the stage 100 and is used to separate the workpieces of the adsorption component so that the adsorption component only adsorbs a single workpiece.

[0046] The sheet separator 200 separates each sheet of paper at a frequency of at least five times.

[0047] This embodiment of the single-sheet feeding device includes a platform 100 on which workpieces are placed. An adsorption component is located on one side of the platform 100 and is responsible for adsorbing single workpieces. A motion platform is located on the platform 100 and connected to the adsorption component. A sheet separator 200 is installed above the platform 100. When the adsorption component adsorbs a workpiece, it separates excess or adhered workpieces from the adsorbed single workpiece through physical agitation or other separation methods. This design ensures that the adsorption component ultimately only grasps a single workpiece. This design effectively solves the problem of multiple workpieces being adsorbed simultaneously. The sheet separator 200 agitates and separates each workpiece at least five times to ensure that the adsorption component adsorbs only one workpiece at a time. The installation and use of the sheet separator 200 greatly improves the separation accuracy of paper or other workpieces, avoiding the multi-sheet adsorption problem caused by relying solely on vibration or simple mechanical designs in the past. This effective separation technology reduces subsequent process failures and processing errors caused by multi-sheet adsorption, thereby improving the operating efficiency of the production line.

[0048] The sheet separator 200 includes a plurality of separating steel sheets 210, with gaps between the plurality of separating steel sheets 210, and the separating steel sheets 210 are arranged in an inverted stepped shape from bottom to top;

[0049] The sheet separator 200 also includes a mounting post 220, which has a plurality of positioning holes, and the release steel sheet 210 is connected to the positioning holes.

[0050] Five separating steel plates 210 are provided, arranged in a stepped manner along the opposite direction of the conveyor platform. This design aims to effectively separate individual sheets of paper during the adsorption process of the adsorption component. Traditional adsorption-type paper feeding devices are prone to the phenomenon of multiple sheets of paper being adsorbed simultaneously, especially when the workpiece is thin or has high surface friction, multiple sheets of paper tend to stick together, affecting the accuracy of paper feeding. By designing the separating steel plates 210 and arranging them in a stepped manner, it is ensured that multiple sheets of paper can be effectively separated during each adsorption process, so that the adsorption component can only adsorb a single sheet of paper at a time, avoiding the situation of multiple sheets being fed together.

[0051] The working principle of the fiberglass sheet is based on physical prying to separate the sheets. After the conveying component 900 moves the lifting component 700 to the preset adsorption position, the adsorption component begins to adsorb the workpiece through vacuum adsorption. After adsorption is completed, the lifting component 700 moves away from the conveying platform. At the same time, the separating steel sheet 210 comes into contact with the workpiece and separates the workpiece by physical prying. Since the separating steel sheets 210 are arranged in a stepped manner, the steel sheet closest to the adsorption component first pries the workpiece once, and then the other steel sheets perform multiple separation actions on the workpiece in sequence. The separation action frequency is at least five times per sheet to ensure that multiple sticky workpieces can be separated, leaving only the workpiece closest to the adsorption component to be picked up.

[0052] The mounting column 220 has several positioning holes. The horizontal and vertical distances between the release steel plate 210 and the conveyor platform can be adjusted through these holes. Similarly, the distance between the release steel plate 210 of the sheet separator 200 and the conveyor platform can be adjusted via the positioning holes on the mounting column 220, thus accommodating workpieces of different thicknesses. Furthermore, the sheet separator 200 performs at least five separation actions on each sheet of paper to ensure that multiple workpieces are not picked up. The lifting assembly 700 returns to its origin under the action of the conveyor assembly 900 and then moves towards the conveyor platform. During this process, the adsorption assembly adsorbs the workpieces on the conveyor platform. The sheet separator 200 is positioned near the adsorption assembly, and its release steel plate 210 performs at least five separation actions on the adsorbed workpieces to ensure that the adsorption assembly adsorbs only a single workpiece. This design effectively prevents multiple sheets of paper from being adsorbed simultaneously, ensuring accurate paper feeding. The stepped arrangement of the sheet separator 200 enables the separation steel sheet 210 to separate the workpiece evenly and effectively, while the positioning holes on the mounting post 220 allow for fine-tuning of the position of the separation steel sheet 210 to accommodate workpieces of different thicknesses.

[0053] The adsorption assembly includes a plurality of suction nozzles 400, all of which are located on one side close to the sheet divider 200, and the position of the suction nozzles 400 corresponds to the side of the conveying direction of the workpiece.

[0054] It also includes a vibrator 410, which is mounted on the adsorption assembly.

[0055] This device is used in printing equipment where the workpiece is paper or other flexible materials. Because paper is flexible, it is easy for it to stick together or be damaged during the adsorption process. Therefore, the suction nozzle 400 is designed on one side of the conveying direction. This design allows the suction nozzle 400 to be flexible when adsorbing paper, according to the characteristics of the paper. Therefore, the suction nozzle 400 adsorbs the side of the paper being conveyed. After adsorbing this side, it is directly conveyed to the next station along the conveying direction, reducing the possibility of multiple sheets of paper sticking together or paper being damaged during the adsorption process.

[0056] During the process of the workpiece being adsorbed by the suction nozzle 400, the vibrator 410 generates a slight vibration. If there are multiple sheets stuck together or the adhesion is strong, the excess workpiece can be separated under the action of the vibrator 410. This design further ensures that only a single sheet of paper is picked up each time.

[0057] The motion platform also includes a conveying component 900, a lifting component 700, and a support arm 710. The lifting component 700 is slidably connected to the conveying component 900. The conveying component 900 drives the lifting component 700 to reciprocate along the length of the platform 100. The lifting component 700 drives the adsorption component to move closer to or away from the platform 100. The support arm 710 is disposed on the platform 100 and extends along the conveying direction of the workpiece.

[0058] A conveying assembly 900 and a lifting assembly 700 are installed on the stage 100. The lifting assembly 700 is slidably connected to the conveying assembly 900. Specifically, the conveying assembly 900 includes a slide rail 910, a slider 920, and a drive motor. The slide rail 910 is located along the length of the stage 100 and is fixedly connected. Under the drive motor, the slider 920 slides on the slide rail 910. The lifting assembly 700 includes a drive screw 720, a lifting platform 730, and a first sensor 740. The lifting platform 730 moves downward or upward under the action of the drive screw 720. 0 is used to detect whether the lifting platform 730 has reached the paper suction position; the lifting platform 730 is provided with a suction component along the side away from the mounting bracket. The suction component includes a second sensor 800. When the conveying component 900 drives the lifting component 700 to the preset origin, the lifting platform 730 moves towards the conveying platform under the action of the drive screw 720. When the first sensor 740 detects that the lifting platform 730 has reached the suction position, the second sensor 800 receives and transmits a signal, and the suction component begins to suction the workpiece on the conveying platform. The lifting platform 730 moves upward while the sheet separator 200 moves the workpiece.

[0059] The conveying assembly 900 drives the lifting assembly 700 to reciprocate along the length of the stage 100, i.e., the X-axis, precisely positioning it above the workpiece to be adsorbed. The lifting assembly 700 is slidably connected to the conveying assembly 900, enabling it to drive the adsorption assembly closer to or away from the stage 100 in the Z-axis direction. When the adsorption assembly moves above the paper, the lifting assembly 700 moves downwards, causing the adsorption assembly to contact and adsorb the paper. Subsequently, the lifting assembly 700 rises, picking up the paper from the stage 100. The support arm 710 is designed to move the paper to the next... In the process of conveying the paper, since the paper has been lifted after adsorption, the support arm 710 can effectively convey the workpiece to the next stage along the side of the suction nozzle 400 that has picked it up. This design takes into account the flexible characteristics of the paper. When the suction nozzle 400 adsorbs the paper, it directly adsorbs and conveys it along the conveying direction, thereby reducing the paper's flipping and friction during the adsorption process, reducing the possibility of multiple sheets of paper sticking together, and protecting the paper from damage. In this way, the paper can be moved directly to the next station along the conveying direction after adsorption, improving the overall conveying efficiency and reliability.

[0060] The adsorption assembly also includes a connecting rod 300, and the suction nozzle 400 is connected to the lifting assembly 700 through the connecting rod 300.

[0061] The adsorption assembly includes a connecting rod 300, one end of which is connected to a suction nozzle 400, and the other end of which is slidably connected to a lifting assembly 700. The connecting rod 300 and the lifting platform 730 are slidably connected. Depending on the size of different workpieces, the operator can adjust the horizontal distance between the suction nozzle 400 assembly and the lifting platform 730. This design aims to allow the suction nozzle 400 to adapt to workpieces of various sizes and thicknesses. By adjusting the adsorption position of the suction nozzle 400, the adsorption assembly can more flexibly handle workpieces of different sizes or other materials, thereby enabling the device to have a wider range of applications, adapt to various materials of different specifications, and improve the system's versatility.

[0062] The lifting assembly 700 is driven by a lead screw.

[0063] In addition, in this embodiment, the lifting assembly 700 is driven by a lead screw. The lead screw drive system can control its lifting speed through a stepper motor or a servo motor. Compared with the single fixed speed and rapid reciprocating motion of a cylinder, the speed of the lead screw drive can be precisely adjusted as needed, thereby ensuring that the system can provide sufficient time for paper separation during the workpiece adsorption process. Unlike the rapid reciprocating motion of a cylinder drive, the lead screw drive can ensure that enough time is left for the sheet separator 200 to complete the separation operation when adsorbing the workpiece, avoiding the next round of operation before the paper is completely separated due to excessively fast movement. Through this precise control, the lifting assembly 700 can operate more calmly when adsorbing workpieces, avoiding the situation of multiple workpieces sticking together during adsorption.

[0064] Positioning pieces 500 are also provided on both sides of the platform 100 in the width direction, and the positioning pieces 500 are slidably connected to the platform 100.

[0065] A sliding plate 600 is provided on the side of the stage 100 away from the adsorption component, and the sliding plate 600 is bolted to the stage 100.

[0066] Positioning plates 500 are positioned on both sides of the width direction of the platform 100. The platform 100 is provided with a slide rail 120, which slidably connects to two sliding blocks 130. Each sliding block 130 is correspondingly provided with a positioning plate 500. The positioning plates 500 are slidably connected to the platform 100 through the connection and cooperation of the slide rail 120 and the sliding blocks 130. In addition, the platform 100 is provided with several sets of adjustment holes 110. The sliding plate 600 is an L-shaped plate, which is bolted to the adjustment holes 110. The operator can adjust the installation of the sliding plate 600 and the adjustment holes 110 according to the size of the workpiece. Through this design, the positioning plates 500 and the sliding plates 600 can be adjusted according to the workpiece or the width of the workpiece. The main purpose of the positioning plate 500 design is to ensure that the workpiece remains aligned on the conveyor platform and does not become misaligned. The positioning plate 500 ensures that the workpiece accurately enters the next stage. Without it, workpieces would be randomly stacked or overlapped on the conveyor platform, deviating from the conveyor path. This would prevent the adsorption component from accurately positioning and picking up the workpiece, or even result in the workpiece not being adsorbed or being adsorbed incorrectly, thus reducing the equipment's working accuracy. Therefore, the positioning plate 500 is designed so that the operator can adjust its position according to the workpiece's size, ensuring the workpiece width matches the spacing of the positioning plates 500. When the workpiece is on the conveyor platform, the positioning plate 500 effectively prevents it from deviating from the conveyor path, ensuring the workpiece always remains in the correct adsorption position. The sliding plate 600 can be flexibly adjusted in position, providing precise guidance for workpieces of different sizes.

Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
