Description

Technical Field

[0001] This utility model relates to the field of pencil manufacturing technology, specifically to an automatic pencil inserter. Background Technology

[0002] To overcome the drawbacks of manual operation, some automated pen inserting devices have emerged on the market. These devices typically have automatic pen feeding and tray feeding functions, enabling them to automatically insert the pen barrel into a horizontally placed pen tray.

[0003] For example, Chinese patent application number CN202122470691.X describes a fully automatic four-stage pencil-dipping line, comprising an automatic pencil insertion device for inserting pencils onto a pencil tray, a UV dipping device, a second dipping device, a third dipping device, a dipping selection and return device, a fourth dipping device, and a pencil removal device. The automatic pencil insertion device, UV dipping device, and second dipping device are connected sequentially. The second, third, and fourth dipping devices are arranged longitudinally in parallel. The dipping selection and return device includes a dipping input line and a return output line. The pencil removal device is connected to the return output line to remove pencils from the pencil tray delivered by the return output line. This invention features automatic tray feeding and automatic pencil removal functions, fully automated operation, and can automatically complete multiple dipping stages. Furthermore, the number of dipping stages is adjustable, making it flexible in use and highly efficient.

[0004] This fully automatic four-piece pen-insertion line discloses part of the automatic pen-insertion device, but it uses a single set of rotary cylinders to flip the pen tray full of pens. Rotary cylinders are expensive, and after long-term operation, the center line of the rotating shaft of the single set of rotary cylinders will shift, which can easily cause damage to the rotary cylinders.

[0005] Based on this, the present invention designs an automatic pen inserter to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic pen inserter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic pen inserter, comprising a pen feeding mechanism arranged horizontally for conveying pencil shafts, a tray feeding mechanism arranged vertically for conveying an empty pen tray placed vertically, a pen inserting mechanism arranged vertically for inserting pencil shafts conveyed by the pen feeding mechanism into the pen tray, and a conveying mechanism for vertically outputting a pen tray with pencil shafts inserted horizontally. The tray feeding mechanism is provided with a push plate mechanism on the side opposite to the pen inserting mechanism. The conveying mechanism includes two sets of conveying frames and a pushing mechanism. Supporting conveying wheels are arranged in an array on the inner side of both sets of conveying frames. A pen tray flipping mechanism is arranged between the two sets of conveying frames. A flipping drive mechanism is installed on the corresponding side conveying frame on one side of the pen tray flipping mechanism.

[0008] Preferably, the pen tray flipping mechanism includes a flipping plate, a first L-shaped component is fixedly connected to the left side of the flipping plate, a side posture group cylinder is horizontally placed on the top of the flipping plate, a second L-shaped component is fixed to the flipping part of the side posture group cylinder, the horizontal parts of the first L-shaped component and the second L-shaped component are arranged facing each other, a locking shaft block is fixedly connected to the top right corner of the flipping plate, and a limiting block for limiting the pen tray is provided on the front side of the flipping plate.

[0009] Preferably, the flipping drive mechanism includes a displacement plate located on the front side of the conveyor frame, a slide rail slider assembly installed between the displacement plate and the conveyor frame, a straight rack horizontally mounted on the top of the displacement plate, a drive cylinder fixedly connected to the conveyor frame, the telescopic end of the drive cylinder fixedly connected to the displacement plate, bearing seats fixedly connected to the top of both sets of the conveyor frames, and rotating shafts fixedly connected to corresponding side locking shaft blocks rotatably connected inside both sets of the bearing seats, a gear fixedly connected to the rotating shaft located on one side of the straight rack, the gear meshing with the straight rack, and hydraulic buffers that limit the position of the displacement plate installed on the left and right sides.

[0010] Preferably, the pushing mechanism includes a linear slide and an insert plate fixed to the displacement portion of the linear slide, and the vertical surface of the first L-shaped member has an insertion hole through which the insert plate can pass.

[0011] Preferably, the flip plate is provided with weight-reducing holes evenly spaced.

[0012] Compared with the prior art, the beneficial effects of this utility model are: It achieves fully automated and efficient production: Through the coordinated work of the pen feeding mechanism, the plate feeding mechanism, the pen insertion mechanism and the conveying mechanism, the entire process from pen barrel conveying, pen plate conveying, automatic pen insertion to finished product output is automated, which greatly improves production efficiency and reduces labor costs and labor intensity.

[0013] The output process is smooth and effectively protects the product: The conveying mechanism uses an array of support conveying wheels to support the pencil tray, providing a stable and continuous support surface. This prevents the pencil tray from tilting or getting stuck during the conveying process and ensures that the pencils inserted in the pencil tray will not collide or be damaged due to shaking.

[0014] The innovative automatic pen tray orientation conversion function: Through the designed pen tray flipping mechanism and flipping drive mechanism, the pen tray, after being inserted and in an upright position, can be automatically and smoothly flipped to a horizontal position before being output. This design solves the problem of inconvenient stacking and transportation of upright pen trays, allowing them to seamlessly connect to subsequent packaging processes, greatly improving the continuity and automation of the production line.

[0015] Compact structure, precise and reliable operation: The tilting drive mechanism adopts a transmission method of "cylinder + rack and pinion + gear", which provides smooth and precise power transmission, is inexpensive, and is not easily damaged. The displacement plate position is limited by a hydraulic damper, which ensures accurate control of the tilting angle.

[0016] The pushing mechanism and the flipping mechanism work together ingeniously. The insert plate can pass through the insertion hole on the first L-shaped part to push the pen disk, realizing the seamless transfer of the pen disk from the flipping station to the output station. The action is precise and without interference.

[0017] The limiting block on the flip plate and the second L-shaped component driven by the side posture group cylinder together form a reliable clamping and positioning of the pen tray, ensuring that the pen tray will not come loose during the flipping process and that the flipping action is stable.

[0018] The weight-reducing holes on the flip plate reduce the weight of moving parts and lower the drive load while ensuring structural strength. This helps improve response speed and running stability, and also saves materials.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] Please see Figure 1-4 This utility model provides an automatic pen inserter technical solution: an automatic pen inserter includes a pen feeding mechanism 110 arranged horizontally for feeding pencils, a tray feeding mechanism 120 arranged vertically for feeding an empty pen tray 800, a pen inserting mechanism 130 arranged vertically for inserting pencils fed by the pen feeding mechanism 110 into the pen tray 800, and a conveying mechanism 140 for vertically outputting the pen tray 800 with pencils inserted horizontally. The tray feeding mechanism 120 has a push plate mechanism 150 on the side opposite to the pen inserting mechanism 130. The pencil feeding mechanism 110 includes a pencil barrel conveying bucket and a pencil barrel conveyor belt arranged horizontally below the pencil barrel conveying bucket. The bottom of the pencil barrel conveying bucket is slidably connected to the frame along the horizontal direction via a horizontal slide rail slider assembly. A pencil drop channel is vertically provided below the output end of the pencil barrel conveyor belt. A pencil drop plate is fixedly connected to the lower end of the pencil drop channel. Several pencil drop slots are evenly distributed along the horizontal direction on the pencil drop plate. A pencil drop power source is also provided below the pencil barrel conveying bucket, which is fixedly connected to the frame to drive the pencil barrel conveying bucket to move horizontally. The pencil barrel conveying bucket can move horizontally above the pencil drop plate to ensure that pencil barrels are evenly distributed in the pencil drop slots. The tray feeding mechanism 120 includes a tray conveyor belt driven by a power mechanism; the push plate mechanism 150 includes a first tray feeding power source and a second tray feeding power source. The first tray feeding power source is horizontally disposed at the rear end of the tray conveyor belt, and a first push block for pushing the tray 800 into the pen insertion mechanism 130 is fixedly connected to the first tray feeding power source; the second tray feeding power source is horizontally disposed above the first tray feeding power source, and a second push block for pushing the tray 800 into the conveying mechanism 140 is fixedly connected to the second tray feeding power source. The pen insertion mechanism 130 includes a pen feeding plate for arranging and placing pencils, a first pen tray clamp located on the rear side of the pen feeding plate for holding the pen tray 800, a pen tray lifting mechanism for driving the first pen tray clamp to lift and lower, and a pen feeding drive group for driving the pen feeding plate to move and insert pencils into the pen tray 800 of the first pen tray clamp. The rear end of the pen feeding plate is provided with several pen slots for placing pencils located directly below the pen drop slots. Each pen slot is arranged in a one-to-one correspondence with the pen drop slot. The pen tray 800 is provided with several pen holes for inserting pencils. The distribution of each pen slot on the pen feeding plate corresponds one-to-one with each row of pen holes on the pen tray 800. The longitudinal length of the pen slot is less than the length of the pencil.

[0025] The pen tray lifting mechanism includes a pen insertion lifting bracket fixed to the frame. The pen insertion lifting bracket is equipped with a pen tray lifting plate that is driven to move vertically by a vertical screw slide rail assembly. When inserting a pen, the pen is inserted by pushing the pen feeding plate. During the pushing process, the first pen tray clamp holds the pen tray 800 and lifts it row by row to ensure that the pen tray 800 is filled with pencils. The first pen tray clamp includes an upper clamp and a lower clamp arranged opposite each other at the upper end of the pen tray lifting plate. The upper clamp and the lower clamp are both slidably connected to the pen tray lifting plate in the horizontal direction via a horizontal slide rail slider assembly. The ends of the upper clamp and the lower clamp away from the pen feeding plate are fixedly connected by a connecting rod. A clamping power source is fixedly connected to the side of the pen tray lifting plate near the connecting rod. The end of the power source rod of the clamping power source is connected to the connecting rod to drive the upper clamp and the lower clamp to move horizontally. The ends of the upper clamp and the lower clamp near the pen feeding plate are respectively provided with an upper hook with the hook head facing downward and a lower hook with the hook head facing upward. The conveying mechanism 140 includes two sets of conveying frames 141 and a pushing mechanism 142. The inner sides of the two sets of conveying frames 141 are arranged in an array to support conveying wheels. A pen tray flipping mechanism 143 is arranged between the two sets of conveying frames 141. A flipping drive mechanism 144 is installed on the corresponding side conveying frame 141 on one side of the pen tray flipping mechanism 143.

[0026] Furthermore, the pen tray flipping mechanism 143 includes a flipping plate 1431, a first L-shaped member 1432 fixedly connected to the left side of the flipping plate 1431, a side posture group cylinder 1433 horizontally placed on the top of the flipping plate 1431, a second L-shaped member 1434 fixedly connected to the flipping part of the side posture group cylinder 1433, the horizontal parts of the first L-shaped member 1432 and the second L-shaped member 1434 facing each other, a locking shaft block 1435 fixedly connected to the top right corner of the flipping plate 1431, and a limiting block 1436 for limiting the pen tray 800 is provided on the front side of the flipping plate 1431.

[0027] Furthermore, the flipping drive mechanism 144 includes a displacement plate 1441 located in front of the conveyor frame 141. A slide rail slider assembly 1442 is installed between the displacement plate 1441 and the conveyor frame 141. A rack 1443 is horizontally installed on the top of the displacement plate 1441. A drive cylinder 1444 is fixedly connected to the conveyor frame 141. The telescopic end of the drive cylinder 1444 is fixedly connected to the displacement plate 1441. A bearing seat 1445 is fixedly connected to the top of both sets of conveyor frames 141. A rotating shaft 1446 is rotatably connected inside both sets of bearing seats 1445 and fixedly connected to the corresponding side locking shaft block 1435. A gear 1447 is fixedly connected to the rotating shaft 1446 located on one side of the rack 1443. The gear 1447 meshes with the rack 1443. Hydraulic buffers 1448 that limit the position of the displacement plate 1441 are installed on the left and right sides.

[0028] Furthermore, the pushing mechanism 142 includes a linear slide and an insert plate fixed to the displacement portion of the linear slide, and the vertical surface of the first L-shaped member 1432 is provided with an insertion hole through which the insert plate can pass.

[0029] Furthermore, the flip plate 1431 is evenly provided with weight reduction holes; the weight reduction holes on the flip plate reduce the weight of moving parts and reduce the driving load while ensuring structural strength, which is conducive to improving response speed and running stability, and at the same time saving materials.

[0030] After the pencils are inserted, the push plate mechanism on one side of the feeding mechanism actuates, pushing the upright pencil tray filled with pencils into the pencil tray flipping mechanism of the conveying mechanism. The pencil tray is placed on the flipping plate, supported on one side by the first L-shaped component and on the other side by the second L-shaped component driven by the side posture group cylinder. At the same time, the limiting block limits the pencil tray laterally, thus supporting the pencil tray on the flipping plate.

[0031] The drive cylinder of the flipping mechanism is activated, pushing the displacement plate along the slide rail slider assembly. The rack on the displacement plate moves accordingly, driving the gear meshing with it to rotate. The gear, via a rotating shaft, drives the entire flipping plate (along with the pen tray on it) to rotate 90 degrees around the axis of the shaft, changing the pen tray from an upright to a horizontal position. A hydraulic damper limits the travel end of the displacement plate, ensuring the flipping angle is accurately achieved.

[0032] After the flipping is complete, the side-positioning cylinder retracts, and the second L-shaped component flips upward. Then, the linear slide of the pushing mechanism activates, driving the insert plate to move horizontally. The insert plate passes through the insertion hole on the vertical surface of the first L-shaped component, pushing the pen tray, which is already in a horizontal position, away from the flipping plate and into the conveying channel formed by the support conveyor wheels on two sets of conveyor frames. The pen tray is smoothly output on the support conveyor wheels and proceeds to the next process.
