Description

Technical Field

[0001] This utility model relates to the field of absorbent pad sorting and transportation technology, specifically, to an automatic counting, sorting and transportation device for absorbent pads. Background Technology

[0002] Absorbent pads are thin pads made of polymer material used to absorb and lock in moisture. They are usually placed at the bottom of the packaging boxes of fresh products (such as meat, poultry, and seafood) to absorb blood and juices, keep the product looking dry, extend its shelf life, and prevent cross-contamination.

[0003] In existing technologies, automated production and conveying of absorbent pads are typically used. After the absorbent pads are produced, in order to achieve quantitative grouping for subsequent packaging, photoelectric counters are generally installed on the production line to count the absorbent pads on the conveyor belt. A cylinder-driven cutting device is usually set downstream of the counter on the production line. When the counter reaches the set value, a control signal is triggered. The control signal controls the cylinder to start, causing its piston rod to extend rapidly and break the absorbent pads lined up in the middle, thereby dividing several absorbent pads into a predetermined number of groups.

[0004] However, this method of relying solely on counting and cutting has its drawbacks. Because the conveyor belt runs at a very high speed, the absorbent pads that are cut by the cylinder, although the number is correct, are scattered and cannot be automatically stacked neatly. Therefore, two workers must take turns performing high-intensity manual sorting to organize the scattered absorbent pads into a neat group, and then a third worker is responsible for packing them into boxes. The entire process is heavily reliant on manual labor, resulting in high labor intensity, low efficiency, and high labor costs. Utility Model Content

[0005] The purpose of this invention is to provide an automatic counting, sorting, and conveying device for absorbent pads, in order to solve the problems mentioned in the background art above:

[0006] Although the number of absorbent pads after the cylinder is broken is correct, their posture is scattered and they cannot be automatically stacked neatly. Therefore, two workers must take turns to perform high-intensity manual sorting of the pads. The entire process is heavily reliant on manual labor and is very labor-intensive.

[0007] To address the above problems, the present invention aims to provide an automatic counting, sorting, and conveying device for absorbent pads, including a conveying mechanism. A stacking mechanism is provided on one side of the conveying mechanism. The conveying mechanism includes an assembly frame, and a main shaft is rotatably mounted on one side of the assembly frame. Two conveying wheels are coaxially fixedly mounted on the main shaft. Several placement slots are arranged in a circular array on the circumferential sidewalls of the conveying wheels. The stacking mechanism includes a frame, and rotating shafts are rotatably mounted near both ends inside the frame. Sprockets are coaxially fixedly mounted on the rotating shafts, and the two sprockets are connected by a common chain. Several baffles are fixedly installed at equal intervals on the side of the chain link away from the sprocket. Synchronous belts are provided on both sides of the chain. Synchronous pulleys are coaxially fixedly installed on the shaft at positions corresponding to the synchronous belts. The synchronous belt drive is connected between two corresponding synchronous pulleys. A gap is left between the side of the synchronous belt away from the sprocket and the inner wall of the frame. The portions of the two conveyor wheels near the stacking mechanism extend into the two gaps respectively. When the two sides of the absorbent pad enter the placement slots on the two conveyor wheels respectively, the conveyor wheels transport the absorbent pad to the upper side wall of the synchronous belt and position the absorbent pad between two adjacent baffles.

[0008] As a further improvement to this technical solution, the conveying mechanism also includes several lower guide rollers rotatably mounted on the side of the assembly frame near the main shaft, and all the lower guide rollers are drivenly connected to the same lower conveyor belt.

[0009] As a further improvement to this technical solution, an arc-shaped plate is fixedly installed on the side of the assembly frame near the main shaft, and the upper side wall of the arc-shaped plate slides in contact with the top side inside the lower conveyor belt. The end of the arc-shaped plate near the stacking mechanism extends into the top between the two conveyor wheels.

[0010] As a further improvement to this technical solution, the conveying mechanism also includes several upper guide rollers rotatably mounted on the side of the assembly frame near the main shaft. All the upper guide rollers are drivenly connected to the same upper conveyor belt, which is located above the lower conveyor belt.

[0011] As a further improvement to this technical solution, when the lower conveyor belt transports the absorbent pad to the area below the upper conveyor belt, the upper conveyor belt presses the absorbent pad closer to the lower conveyor belt. When both sides of the absorbent pad enter the storage slots on the two conveyor wheels, the absorbent pad disengages from the lower and upper conveyor belts.

[0012] As a further improvement to this technical solution, the stacking mechanism also includes two limiting plates that are symmetrically fixedly installed on the side wall of the frame, with the tops of the two timing belts located between the two limiting plates.

[0013] As a further improvement to this technical solution, a support plate is provided on the top side inside the synchronous belt and the chain, and the support plate is fixedly installed on the inner wall of the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This automatic counting, sorting, and conveying device for absorbent pads continuously transports absorbent pads to a stacking mechanism via a conveyor. The pads are received one by one by a trough on the conveyor wheel and transferred to a synchronous belt. Simultaneously, a chain drives baffles to move synchronously, causing the absorbent pads to be stacked laterally between adjacent baffles in a side-standing position, forming a predetermined number of groups. This action achieves automatic counting and neat stacking of the absorbent pads. The baffles prevent the absorbent pads from tipping over during stacking. This design replaces the cumbersome process of existing technologies that require two people to manually sort the pads and one person to pack them. Only one worker is needed at the end of the synchronous belt to remove and pack the entire group of absorbent pads, thus saving labor and improving packaging efficiency. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1 As shown, the purpose of this embodiment is to provide an automatic counting, sorting and conveying device for absorbent pads, including a conveying mechanism 1, and a stacking mechanism 2 is provided on one side of the conveying mechanism 1. The conveying mechanism 1 is responsible for continuously conveying the absorbent pads to the stacking mechanism 2, and the stacking mechanism 2 stacks the absorbent pads horizontally into a predetermined number of groups, which facilitates subsequent sorting and packaging.

[0030] Reference Figures 2-4 The conveying mechanism 1 includes an assembly frame 11. A main shaft 12 is rotatably mounted on one side of the assembly frame 11. Two conveying wheels 13 are coaxially fixedly mounted on the main shaft 12. Several placement slots 131 are arranged in a ring array on the circumferential sidewall of the conveying wheels 13. The placement slots 131 on the two conveying wheels 13 are correspondingly arranged. The conveying mechanism 1 also includes several lower guide rollers 151 rotatably mounted on the side of the assembly frame 11 near the main shaft 12. All lower guide rollers 151 are drivenly connected to the same lower conveyor belt 15. An arc-shaped plate 152 is fixedly mounted on the side of the assembly frame 11 near the main shaft 12, and the upper sidewall of the arc-shaped plate 152 is flush with the interior of the lower conveyor belt 15. The top side sliding contact, the arc plate 152 near the stacking mechanism 2 extends into the top between the two conveyor wheels 13. The conveying mechanism 1 also includes several upper guide rollers 141 rotatably mounted on the side of the assembly frame 11 near the main shaft 12. All upper guide rollers 141 are drivenly connected to the same upper conveyor belt 14. The upper conveyor belt 14 is located above the lower conveyor belt 15. When the upper conveyor belt 14 is located on the lower side and the lower conveyor belt 15 is located on the upper side, they are horizontally set and in contact with each other. When the absorbent pad passes between the upper conveyor belt 14 and the lower conveyor belt 15, the upper conveyor belt 14 and the lower conveyor belt 15 press and convey the absorbent pad.

[0031] Three servo motors are fixedly installed on the side of the assembly frame 11 away from the main shaft 12. The output shafts of the three servo motors are coaxially fixedly connected to one of the lower guide rollers 151, one of the upper guide rollers 141 and the main shaft 12, respectively, and are used to drive the lower conveyor belt 15, the upper conveyor belt 14 and the main shaft 12 to rotate. All three servo motors are uniformly coordinated and controlled by an external control device to ensure that the speeds of the lower conveyor belt 15, the upper conveyor belt 14 and the conveyor wheel 13 are matched. This control principle is existing technology and will not be described in detail.

[0032] When the lower conveyor belt 15 transports the absorbent pad to below the upper conveyor belt 14, the upper conveyor belt 14 presses the absorbent pad firmly against the lower conveyor belt 15. The upper and lower sides of the absorbent pad contact the horizontal sections of the upper and lower conveyor belts 14 and 15 respectively, keeping the absorbent pad horizontal. At this time, the moving direction and speed of the parts of the upper and lower conveyor belts 14 and 15 in contact with the absorbent pad are consistent, ensuring smooth transport of the absorbent pad. Furthermore, the width of the absorbent pad is greater than the width of the upper and lower conveyor belts 14 and 15, allowing the sides of the absorbent pad to extend beyond them. When the absorbent pad reaches the position between the two conveyor wheels 13, the opening of one of the placement slots 131 on the conveyor wheel 13 is aligned with the absorbent pad, allowing the two sides of the absorbent pad to enter the two placement slots. Inside the storage groove 131 on the conveyor wheel 13, as the main shaft 12 drives the two conveyor wheels 13 to continue rotating, the conveyor wheels 13 drive the absorbent pad to move synchronously through the storage groove 131. The length of the upper conveyor belt 14 extending towards the stacking mechanism 2 is greater than the length of the lower conveyor belt 15 extending towards the stacking mechanism 2. As the absorbent pad rotates with the conveyor wheel 13, it first separates from the lower conveyor belt 15. The upper conveyor belt 14 cooperates with the conveyor wheel 13 to transport the absorbent pad, preventing the absorbent pad from separating from the conveyor wheel 13 due to centrifugal force. Then, the absorbent pad separates from the upper conveyor belt 14, causing the absorbent pad to lose contact with the lower conveyor belt 15 and the upper conveyor belt 14. After separating from the lower conveyor belt 15 and the upper conveyor belt 14, the absorbent pad is received by the stacking mechanism 2, and several absorbent pads are stacked on the stacking mechanism 2.

[0033] The following details the structure of stacking mechanism 2, referring to... Figure 5 and Figure 6The stacking mechanism 2 includes a frame 21. Inside the frame 21, a rotating shaft 28 is rotatably mounted near both ends. A sprocket 29 is coaxially fixedly mounted on the rotating shaft 28. The two sprockets 29 are connected by the same chain 22. Several baffles 25 are fixedly mounted at equal intervals on the side of the chain link away from the sprocket 29. The spacing between two adjacent baffles 25 is adapted to the thickness of a set of absorbent pads stacked together. Synchronous belts 24 are provided on both sides of the chain 22. The upper sidewall of the synchronous belt 24 is higher than the upper sidewall of the chain 22 to avoid the absorbent pads from contacting the chain 22 and to prevent jamming. Synchronous pulleys 23 are coaxially fixedly mounted on the rotating shaft 28 at positions corresponding to the synchronous belts 24. The synchronous belts 24 are connected between the corresponding two synchronous pulleys 23.

[0034] A drive motor is fixedly installed on the frame 21. The output shaft of the drive motor is coaxially and fixedly connected to one of the rotating shafts 28. After the drive motor starts, its output shaft drives the rotating shaft 28 to rotate, which in turn drives the corresponding sprocket 29 and two synchronous pulleys 23 to rotate, thereby driving the chain 22 and the synchronous belt 24 to rotate synchronously, so that the chain 22 and the synchronous belt 24 run synchronously at the same speed.

[0035] The stacking mechanism 2 also includes two limiting plates 26 that are symmetrically fixedly installed on the upper side wall of the frame 21. The tops of the two synchronous belts 24 are located between the two limiting plates 26. The distance between the two limiting plates 26 on their respective sides is adapted to the width of the absorbent pad. Support plates 27 are provided on the top side inside the synchronous belts 24 and the chain 22. The support plates 27 are fixedly installed on the inner wall of the frame 21. The support plates 27 provide support for the chain 22 and the synchronous belts 24, ensuring that the chain 22 can smoothly convey the baffle 25 and the synchronous belts 24 can smoothly convey the absorbent pad.

[0036] Reference Figure 7 and Figure 8 A gap is left between the side of the synchronous belt 24 away from the sprocket 29 and the inner wall of the frame 21. The parts of the two conveyor wheels 13 near the stacking mechanism 2 extend into the two gaps respectively. When the two sides of the absorbent pad enter the storage slots 131 on the two conveyor wheels 13 respectively, the absorbent pad is sent to the upper surface of the synchronous belt 24 as the conveyor wheels 13 rotate. At this time, the synchronous belt 24 prevents the absorbent pad from continuing to move with the conveyor wheels 13, so that it is removed from the storage slots 131 and transferred to the synchronous belt 24 in a side-standing state.

[0037] If the absorbent pad is the first pad in a set, it will contact one side of a baffle 25. As the synchronous belt 24 transports the absorbent pad, the chain 22 drives the baffle 25 to move synchronously a distance equal to the width of the absorbent pad. The next placement slot 131 on the conveyor wheel 13 will send the subsequent absorbent pad to the synchronous belt 24 in the same way, and it will be close to the previous absorbent pad. This process is repeated to achieve the horizontal stacking of multiple absorbent pads. The number of placement slots 131 on the conveyor wheel 13 corresponds to the predetermined number of pads in a set. Each rotation completes the transport of a set of absorbent pads. At this time, the set of absorbent pads is located between two adjacent baffles 25, and the first and last absorbent pads are in contact with the sides of the two baffles 25 that are close to each other. The two baffles 25 prevent the set of absorbent pads from tipping over. As the synchronous belt 24 and the baffles 25 work together to transport the entire set of absorbent pads to the end of the synchronous belt 24 away from the conveyor mechanism 1, the packing personnel can take the entire set of absorbent pads out from between the two baffles 25 and put them into the packing box for packing.

[0038] The drive motor is also controlled by an external control device to ensure that the speed of the synchronous belt 24 and the conveyor wheel 13 are matched, and that each set of water-absorbing pads can be accurately stacked between adjacent baffles 25. This control principle is existing technology, so it will not be described in detail here.

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 preferred examples and are not intended to limit the utility model.
