Description
Technical Field
[0001] This utility model relates to the field of pen processing equipment technology, and in particular to a feeding device for a pen barrel labeling device. Background Technology
[0002] Pens are commonly used writing tools in daily life. To facilitate pen sales, labels need to be affixed to the pen barrels. Existing technologies include the following labeling methods: First, manually affixing labels to the pen barrels; however, this method is inefficient and cannot meet the needs of large-scale production. Second, using a conveyor chain to feed the pen barrels; however, the following problems arise during the feeding process: First, because the pen tip and pen tail have different shapes, incorrect feeding positions will result in inconsistent label placement, affecting the overall aesthetics of the pen and failing to meet sales requirements. Second, since pen barrels usually have a clip for attaching to books or clothing pockets, the label positions typically need to be fixed, using the clip position as a reference and affixing labels at regular intervals. However, existing pen barrel feeding devices struggle to maintain consistency during feeding; therefore, a new type of feeding device is needed. Summary of the Invention
[0003] To address the aforementioned issues, this invention provides a feeding device for a pen barrel labeling device that improves automation, ensures the pen barrel remains in the same state during processing, and guarantees that labels can be affixed to the same position on the pen barrel when applying labels.
[0004] The technical solution of this utility model: A feeding device for a pen barrel labeling device, comprising a device base, a transmission device connected to the device base, a pen barrel steering device connected to the device base, a labeling machine and a controller connected to the device base. The transmission device includes a fixed frame connected to the device base, a first transmission chain connected to the fixed frame, a second transmission chain connected to the fixed frame, a first drive motor for driving the first transmission chain, and a second drive motor for driving the second transmission chain. The distance between the first and second transmission chains is adapted to the length of the pen barrel to be processed. The pen barrel steering device includes a first CCD vision detection device connected to the device base. The device comprises a first sliding base connected to a base, a rotating shaft connected to the first sliding base, a first fixed base fixedly connected to the rotating shaft, a first hydraulic cylinder for driving the first sliding base to move vertically, and a first rotary motor for driving the rotating shaft to rotate. The first fixed base is provided with a first limiting groove, which is adapted to the shape and size of the pen barrel to be processed. The first sliding base is located between the first transmission chain and the second transmission chain. The labeling machine is located directly above the first fixed frame. The controller is electrically connected to the first CCD vision inspection instrument, the first drive motor, the second drive motor, the first hydraulic cylinder, and the first rotary motor.
[0005] Using the above technical solution, firstly, the pen barrel to be processed is fed through a first transmission chain and a second transmission chain. A controller controls a first drive motor and a second drive motor to drive the first and second transmission chains, respectively, so that the first and second transmission chains together move the pen barrel directly below a first CCD vision inspection instrument. The first CCD vision inspection instrument captures real-time image information of the pen barrel and compares it with stored standard image information. If the two match, the first and second transmission chains continue to feed the pen barrel. If they do not match, the controller controls a first hydraulic cylinder to drive a first sliding base vertically upwards, so that the first fixed... The first limiting groove on the fixed base contacts the pen barrel and lifts it a certain distance. Then, the controller controls the first rotary motor to drive the rotating shaft to rotate 180 degrees, thereby causing the pen barrel to rotate 180 degrees to complete the turning operation. Then, the first sliding base resets, so that the pen barrel is placed on the first and second transmission chains. When the pen barrel moves directly under the labeling machine, the first and second drive motors stop working simultaneously, and the labeling machine completes the labeling work on the pen barrel. This can greatly improve the automation level of the feeding device and ensure that the pen barrel keeps the labeling work in the same direction, thereby improving the consistency of the label position on the processed pen barrel.
[0006] A further feature of this invention includes a pen barrel adjustment device, comprising a second CCD vision inspection instrument connected to the device base, a second sliding base slidably connected to the device base, a second fixed base fixedly connected to the second sliding base, a third sliding base slidably connected to the device base, a fourth sliding base slidably connected to the device base, a first push rod movably connected to the third sliding base, a second push rod movably connected to the fourth sliding base, a second hydraulic cylinder for driving the second sliding base to move vertically, a third hydraulic cylinder for driving the third sliding base to move horizontally, and a third hydraulic cylinder for... The system includes a fourth hydraulic cylinder that drives the fourth sliding base to move horizontally, a second rotary motor that drives the first push rod to rotate, and a third rotary motor that drives the second push rod to rotate. The second fixed base is located between the first and second transmission chains. The second CCD vision inspection instrument is located directly above the second fixed base. The second fixed base is provided with a second limiting groove, which is adapted to the shape and size of the pen barrel to be processed. The controller is electrically connected to the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, the second rotary motor, the third rotary motor, and the second CCD vision inspection instrument.
[0007] Using the above technical solution, when the first and second transmission chains move the pen barrel to directly below the second CCD vision inspection instrument, the second CCD vision inspection instrument captures real-time image information of the pen barrel and compares it with the image information of the pen barrel in the standard state to calculate the angle that the pen barrel needs to rotate. Then, the controller controls the second hydraulic cylinder to drive the second sliding base to move vertically upward, so that the second limiting groove on the second fixed base contacts the pen barrel and raises the pen barrel a certain distance, so that the position of the pen barrel corresponds to the position of the first and second push rods respectively. Then, the controller controls the third and fourth hydraulic cylinders to drive the third sliding base and the second fixed base to move vertically upward respectively. The four sliding bases move in opposite directions, causing the first and second push rods to clamp the two ends of the pen barrel respectively. Then, by controlling the second and third rotary motors, the first and second push rods are rotated in the same direction by a certain angle, causing the pen barrel to rotate accordingly. This ensures that the pen barrel remains in the same state before labeling. Then, the third and fourth hydraulic cylinders drive the third and fourth sliding bases to reset, and the second hydraulic cylinder drives the second sliding base to reset, thus returning the pen barrel to the first and second transmission chains. Then, the labeling machine performs the labeling operation. This further improves the automation level of the device and increases the product qualification rate.
[0008] A further feature of this invention is that the second transmission chain is provided with a plurality of limiting protrusions, and the limiting protrusions are provided with a third limiting groove. The cross-sectional shape of the third limiting groove is adapted to the cross-sectional shape of the pen barrel and the pen clip joint to be processed.
[0009] By adopting the above technical solution, since the third limiting groove is provided on the positioning protrusion and the cross-sectional shape of the third limiting groove is adapted to the cross-sectional shape of the pen barrel and the pen clip joint, when the pen barrel is rotated to the correct angle and placed on the limiting protrusion, it can be ensured that the pen barrel will not undergo relative displacement during transmission, thereby further ensuring that the pen barrel remains in the same state before labeling and improving the product qualification rate.
[0010] A further feature of this invention is that a rubber pad is provided on the third limiting groove, the cross-sectional shape of the inner wall of the rubber pad is adapted to the cross-sectional shape of the pen barrel and the pen clip joint to be processed, and the shape of the outer surface of the rubber pad is adapted to the shape and size of the inner wall of the third limiting groove.
[0011] By adopting the above technical solution, since the third limiting groove is equipped with a rubber pad made of rubber, the friction force on the pen barrel can be increased, further preventing the pen barrel from undergoing relative displacement during transmission, thereby improving the product qualification rate.

Detailed Implementation
[0016] like Figure 1-3 As shown, a feeding device for a pen barrel labeling device includes a base 1, a transmission device 2 connected to the base 1, a pen barrel steering device 3 connected to the base 1, a labeling machine 4 connected to the base 1, and a controller 5. The transmission device 2 includes a fixed frame 6 connected to the base 1, a first transmission chain 7 connected to the fixed frame 6, a second transmission chain 8 connected to the fixed frame 6, a first drive motor 9 for driving the first transmission chain 7, and a second drive motor 10 for driving the second transmission chain 8. The distance between the first transmission chain 7 and the second transmission chain 8 is adapted to the length of the pen barrel to be processed. The pen barrel steering device 3 includes a first CCD vision inspection instrument 11 connected to the base 1, and a labeling machine 4 connected to the base 1. The system comprises a first sliding base 12, a rotating shaft 13 connected to the first sliding base 12, a first fixed base 14 fixedly connected to the rotating shaft 13, a first hydraulic cylinder 15 for driving the first sliding base 12 to move vertically, and a first rotary motor 16 for driving the rotating shaft 13 to rotate. The first fixed base 14 is provided with a first limiting groove 17, which is adapted to the shape and size of the pen barrel to be processed. The first sliding base 12 is located between the first transmission chain 7 and the second transmission chain 8. The labeling machine 4 is located directly above the first fixed frame 6. The controller 5 is electrically connected to the first CCD vision inspection instrument 11, the first drive motor 9, the second drive motor 10, the first hydraulic cylinder 15, and the first rotary motor 16.
[0017] First, the pen barrel to be processed is fed through the first transmission chain 7 and the second transmission chain 8. The controller 5 controls the first drive motor 9 and the second drive motor 10 to drive the first transmission chain 7 and the second transmission chain 8 respectively, so that the first transmission chain 7 and the second transmission chain 8 together move the pen barrel directly below the first CCD vision inspection instrument 11. The first CCD vision inspection instrument 11 captures real-time image information of the pen barrel and compares it with stored standard image information. If the two match, the first transmission chain 7 and the second transmission chain 8 continue to feed the pen barrel. If the two do not match, the controller 5 controls the first hydraulic cylinder 15 to drive the first sliding base 12 to move vertically upwards, so that the first fixed base... The first limiting groove 17 on the 14 contacts the pen barrel and lifts it a certain distance. Then, the controller 5 controls the first rotary motor 16 to drive the rotating shaft 13 to rotate 180 degrees, thereby causing the pen barrel to rotate 180 degrees to complete the turning operation. Then, the first sliding base 12 is reset, so that the pen barrel is also placed on the first transmission chain 7 and the second transmission chain 8. When the pen barrel moves to the bottom of the labeling machine 4, the first drive motor 9 and the second drive motor 10 stop working at the same time and the labeling machine 4 completes the labeling operation on the pen barrel. This can greatly improve the automation level of the feeding device and ensure that the pen barrel keeps the same direction for labeling, thereby improving the consistency of the label position on the processed pen barrel.
[0018] It also includes a pen barrel adjustment device 18, which includes a second CCD vision inspection instrument 19 connected to the device base 1, a second sliding base 20 slidably connected to the device base 1, a second fixed base 21 fixedly connected to the second sliding base 20, a third sliding base 22 slidably connected to the device base 1, a fourth sliding base 23 slidably connected to the device base 1, a first push rod 24 movably connected to the third sliding base 22, a second push rod 25 movably connected to the fourth sliding base 23, a second hydraulic cylinder 26 for driving the second sliding base 20 to move vertically, a third hydraulic cylinder 27 for driving the third sliding base 22 to move horizontally, and a fourth sliding base 28 for driving the fourth sliding base 23. The second fixed base 21 is located between the first transmission chain 7 and the second transmission chain 8. The second CCD vision inspection instrument 19 is located directly above the second fixed base 21. The second fixed base 21 is provided with a second limiting groove 31, which is adapted to the shape and size of the pen barrel to be processed. The controller 5 is electrically connected to the second hydraulic cylinder 26, the third hydraulic cylinder 27, the fourth hydraulic cylinder 28, the second rotary motor 29, the third rotary motor 30, and the second CCD vision inspection instrument 19.
[0019] When the first transmission chain 7 and the second transmission chain 8 move the pen to directly below the second CCD vision inspection instrument 19, the second CCD vision inspection instrument 19 captures real-time image information of the pen and compares it with the image information of the pen in the standard state to calculate the angle that the pen needs to rotate. Then, the controller 5 controls the second hydraulic cylinder 26 to drive the second sliding base 20 to move vertically upward, so that the second limiting groove 31 on the second fixed base 21 contacts the pen and raises the pen a certain distance, so that the position of the pen corresponds to the position of the first top rod 24 and the second top rod 25 respectively. Then, the controller 5 controls the third hydraulic cylinder 27 and the fourth hydraulic cylinder 28 to drive the third sliding base 22 and the fourth sliding base 25 respectively. The pen barrel moves in opposite directions, causing the first push rod 24 and the second push rod 25 to clamp the two ends of the pen barrel respectively. Then, by controlling the second rotary motor 29 and the third rotary motor 30, the first push rod 24 and the second push rod 25 are rotated in the same direction by a certain angle, so that the pen barrel rotates by a certain angle, thus ensuring that the pen barrel remains in the same state before labeling. Then, the third hydraulic cylinder 27 and the fourth hydraulic cylinder 28 drive the third sliding base 22 and the fourth sliding base 23 to reset, and the second hydraulic cylinder 26 drives the second sliding base 20 to reset, so that the pen barrel is reset to the first transmission chain 7 and the second transmission chain 8. Then, the labeling machine 4 performs the labeling work. This can further improve the automation level of this device and improve the product qualification rate.
[0020] The second transmission chain 8 is provided with a plurality of limiting protrusions 32, and the limiting protrusions 32 are provided with a third limiting groove 33. The cross-sectional shape of the third limiting groove 33 is adapted to the cross-sectional shape of the pen barrel and pen clip joint to be processed.
[0021] Because the protrusion has a third limiting groove 33, and the cross-sectional shape of the third limiting groove 33 is adapted to the cross-sectional shape of the pen barrel and the pen clip joint, when the pen barrel is rotated to the correct angle and placed on the limiting protrusion 32, it can be ensured that the pen barrel will not be relatively displaced during the transmission process, thereby further ensuring that the pen barrel remains in the same state before labeling and improving the product qualification rate.
[0022] A rubber pad 34 is provided on the third limiting groove 33. The cross-sectional shape of the inner wall of the rubber pad 34 is adapted to the cross-sectional shape of the pen barrel and pen clip joint to be processed. The outer surface shape of the rubber pad 34 is adapted to the shape and size of the inner wall of the third limiting groove 33.
[0023] Because the third limiting groove 33 is equipped with a rubber pad 34, which is made of rubber, the friction force on the pen barrel can be increased, further preventing the pen barrel from shifting relative to the ground during transmission, thereby improving the product qualification rate.
