Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and specifically to a conveyor that facilitates the collection and conveying of pallets. Background Technology

[0002] Currently, during the stacking and conveying of profiles, special pads are placed between each layer to prevent surface scratches caused by contact between different layers. These pads are specially designed with a cushioning material on their surface, effectively isolating direct friction between profiles while preventing damage to the profiles from the pads themselves. When the clamping mechanism handles the profiles, it indirectly lifts the profiles placed on them by gripping and raising the pads. This design ensures both handling efficiency and maximizes the protection of the profile surface integrity. After handling is complete, these pads that have carried the profiles need to be centrally transported to a collection area.

[0003] The patent application number CN221624132U discloses a feeding device for a dual-channel cigarette pre-formed carton. According to its specification and drawings, the carton buffer channel includes at least two parallel conveyor belts driven by servo motors.

[0004] However, this solution has certain limitations: 1. When using parallel belt conveyors, the gripping mechanism can pass the pad through the gap between the parallel belt conveyors, allowing the profile on the pad to be placed on the surface of the belt conveyor. However, there is no corresponding structure to collect and transport the pad, which causes inconvenience in the production process. 2. After the belt conveyor supports the profile, the pad is released from its support and is in a state of waiting to be recycled. Therefore, how to quickly receive the pad that needs to be recycled is also a problem that needs to be considered. Summary of the Invention

[0005] This invention addresses the aforementioned problems encountered by belt conveyors in transporting long profiles. It proposes a conveyor that facilitates the collection and transport of pads. Through automated connection and transport, it efficiently recovers pads between stacked profiles to match production rhythm and significantly improves overall operational efficiency.

[0006] The objective of this invention is achieved through the following technical solution: a conveyor for facilitating the collection and transport of mats, comprising several belt conveyors arranged in parallel, with a clearance between the belt conveyors greater than the width of the mat, the surfaces of the belt conveyors being used to support profiles, and several conveying support bodies arranged in parallel below the belt conveyors and perpendicular to the belt conveyors, each conveying support body having pulleys at both ends, a conveying belt that moves with the rotation of the pulleys on each conveying support body, and a pallet body that can move up and down and is used to support the mats on the side of the conveying support body, and a pushing mechanism for driving the pallet body to move up and down on the side of the conveying support body.

[0007] Preferably, each of the conveying support bodies is provided with several support seats at its bottom, and adjacent support seats are fixedly connected by support crossbars. A pushing mechanism is installed on the side wall of each support seat. This arrangement is for the purpose of fixing the pushing mechanism.

[0008] Preferably, each of the support bases is also equipped with a guide rail and a slider slidably connected to the guide rail, and the side wall of the tray body is connected to the slider. This arrangement is to enhance the stability of the tray body during the sliding process.

[0009] Preferably, the pallet body includes a support portion and a bearing portion. The support portion is rectangular in shape, and the bearing portion is disposed on top of the support portion and is shaped like a groove, with the opening size at the top of the groove gradually decreasing towards the bottom.

[0010] Preferably, each of the pushing mechanisms includes a cylinder support column, a first cylinder, and a photoelectric sensor. A cylinder support column is installed on the side wall of each support seat. The cylinder body of each first cylinder is fixedly connected to the cylinder support column, and the piston rod end of the first cylinder is connected to the surface of the support. The cylinder body of the first cylinder is also provided with a photoelectric sensor for monitoring whether there is a pad inside the bearing part.

[0011] Preferably, a second cylinder is fixedly connected to the side wall of each of the support crossbars. The piston rod end of the second cylinder is connected to a pad block with an L-shaped cross section. When the piston rod of the second cylinder is not extended, the top of the pad block is not higher than the top of the conveying support body. This setting is to enable the pad block to block the conveyed pad and prevent the pad carried inside the subsequent frame from overflowing.

[0012] Preferably, each of the conveying support bodies is further provided with a first transmission support plate and a second transmission support plate on its two end sidewalls. A transmission shaft is fixedly installed between adjacent first transmission support plates. A bearing is installed on the surface of the transmission shaft and a pulley is installed on the bearing. A bearing seat is also installed on the second transmission support plate. A drive shaft is provided inside a plurality of bearing seats. A pulley is also installed on the surface of the drive shaft and between adjacent second transmission support plates. A transmission gear is installed on one end of the drive shaft. A motor mounting seat is also provided on the outside of the conveying support body. A drive motor is provided on the motor mounting seat. A drive gear is provided at the end of the shaft of the drive motor and is connected to the transmission gear by a metal chain.

[0013] Preferably, the outside of the conveyor support body is also provided with a frame body whose internal width is greater than the width between the conveyor support bodies arranged side by side. The bottom of the frame body is provided with several wheels, and the frame body is used to receive the pads conveyed by the conveyor belt.

[0014] Compared with the prior art, the present invention has the following beneficial effects: A conveyor support body and a conveyor belt are set parallel below the conveyor line. Furthermore, a liftable pallet body and a pushing mechanism are integrated on this basis, and photoelectric sensors are used for coordinated control. This design fundamentally optimizes the working cycle. As the pallet is being clamped and lowered, it can be released in advance onto the pallet body that has been raised and is waiting. The pallet body carries the pallet down and places it on the continuously running conveyor belt. This achieves the overlap of the time between the material release action and the conveyor belt transmission action, which greatly shortens the waiting time required for each process of receiving the pallet to be recycled, thereby significantly improving the operating efficiency and rhythm of the entire production line. Multiple parallel belt conveyors are used to form clearance gaps, and a vertical pad collection and conveying line is arranged below them. This vertically intersecting layout makes full use of three-dimensional space, and completes the conveying of profiles (above) and the collection and transportation of pads (below) simultaneously within a limited area, making the space planning extremely efficient. The modular design also allows the device to flexibly adapt to different production site layouts and operating height requirements. Photoelectric sensors monitor in real time whether the pallet body is carrying a pad, and automatically control the extension and retraction of the first cylinder based on this signal: that is, the lifting and lowering of the pallet body. This design realizes the automated closed-loop control of the process of receiving the pad and placing the conveyor belt. The system can automatically sense the working status and respond without manual intervention or external timing control. This not only reduces the dependence on complex programming of external control systems and lowers the failure rate, but also enables the system to intelligently adapt to the actual working rhythm and further optimize the process. The conveyor belt needs to run continuously, but when the chassis is fully loaded, the pads brought by the subsequent conveyor belts can be temporarily blocked by raising the pad blocks to prevent them from overflowing or falling and causing chaos, without having to stop the entire upstream production line.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 and Figure 5 As shown, a conveyor for facilitating the collection and transport of pads includes several belt conveyors 1 arranged in parallel, with clearances between the belt conveyors 1 greater than the width of the pad 91. The surfaces of the belt conveyors 1 are used to support profiles 9. A gantry or robotic arm, in conjunction with a clamp, holds the pad 91, lifting the profiles 9 on the surface of the pad 91. This gripping structure is a common technique used by those skilled in the art and will not be described in detail here. After lifting, the profiles 9 are placed on the surface of the belt conveyors 1, while passing through the clearances between the belt conveyors 1 to fall or be placed in a designated area for collection.

[0018] In this embodiment, several conveying support bodies 2 are arranged in parallel below the belt conveyor 1 and perpendicular to the belt conveyor 1. Each conveying support body 2 has a pulley 21 at both ends, and a conveying belt 22 that moves with the rotation of the pulley 21 is fitted on the pulley 21 of each conveying support body 2.

[0019] like Figure 1 As shown, after the gantry crane or robotic arm, in conjunction with the clamp, passes the pad 91 through the clearance gap between several belt conveyors 1, the profile 9 is placed on the surface of the belt conveyor 1. At this time, the pad 91 can continue to be clamped and moved downward until it is placed on the surface of the conveyor belt 22. As the pulley 21 rotates continuously, it drives the conveyor belt 22 to transport the pad 91 to the designated position.

[0020] Please continue to refer to this. Figure 3 The side of the conveying support body 2 is also provided with a pallet body 3 that can move up and down and is used to support the pad 91. The side of the conveying support body 2 is provided with a pushing mechanism 4 for driving the pallet body 3 to move up and down.

[0021] To reduce the time required for the gantry crane or robotic arm to pass through the clearance between several belt conveyors 1 and place the pad 91 on the surface of the conveyor belt 22, the pushing mechanism 4 can push the pallet body 3 upward during the downward movement of the several pads 91, thereby catching the pads 91 to be recycled earlier or faster; subsequently, as the pallet body 3 returns to its initial position, the pads 91 held by the pallet body 3 can be placed on the surface of the conveyor belt 22.

[0022] Please continue to refer to this. Figure 3 Each of the conveying support bodies 2 has several support seats 23 at its bottom. Adjacent support seats 23 are fixedly connected by support crossbars 20. A pushing mechanism 4 is installed on the side wall of each support seat 23. Each of the conveying support bodies 2 has several support seats 23 at its bottom. Adjacent support seats 23 are fixedly connected by support crossbars 20. A pushing mechanism 4 is installed on the side wall of each support seat 23. A guide rail 5 and a slider 51 slidably connected to the guide rail 5 are also installed on the side wall of each support seat 23. The side wall of the pallet body 3 is connected to the slider 51.

[0023] Support base 23 is used to elevate the conveyor support body 2, and the support crossbars 20 between support bases 23 are used to enhance structural strength; at the same time, the overall height of support base 23 can be adjusted according to the needs of production operation height; when the pushing mechanism 4 pushes the pallet body 3 to move up or down, since the pallet body 3 is fixedly connected to the slider 51, the slider 51 slides in the corresponding groove in the guide rail 5 during the movement, playing a supporting and guiding role, further enhancing the moving accuracy of the pallet body 3, and preventing error deviation.

[0024] Please continue to refer to the reference. Figure 4 Each of the conveying support bodies 2 is provided with a first transmission support plate 24 and a second transmission support plate 25 on both end side walls. A transmission shaft 26 is fixedly installed between adjacent first transmission support plates 24. A bearing is installed on the surface of the transmission shaft 26 and a pulley 21 is installed on the bearing. A bearing seat 27 is also installed on the second transmission support plate 25. A drive shaft 28 is provided inside a plurality of bearing seats 27. A pulley 21 is also installed on the surface of the drive shaft 28 and between adjacent second transmission support plates 25. A transmission gear 29 is installed on one end of the drive shaft 28. A motor mounting seat 7 is provided on the outside of the conveying support body 2. A drive motor 71 is provided on the motor mounting seat 7. A drive gear 72 is provided at the end of the shaft of the drive motor 71 and is connected to the transmission gear 29 by a metal chain.

[0025] During the rotation of the drive motor 71, the drive gear 72 is driven to rotate. During the rotation of the drive gear 72, the drive gear 72 and the drive shaft 28 are driven to rotate simultaneously through the metal chain. The drive shaft 28 drives the pulley 21 at one end of the conveyor support body 2 to rotate. At the same time, the pulley 21 at the other end of the conveyor support body 2 rotates simultaneously under the transmission of the conveyor belt 22. As the conveyor belt 22 moves continuously, it can move the pad 91 on its surface until it moves to the designated position.

[0026] Please continue to refer to the reference. Figure 2 and Figure 4 The pallet body 3 includes a support part 31 and a bearing part 32. The support part 31 is rectangular in shape, and the bearing part 32 is disposed on the top of the support part 31 and is shaped as a groove. The opening size of the top of the groove gradually decreases towards the bottom.

[0027] The width of the groove in the bearing part 32 is greater than the width of the pad 91. The opening size at the top of the groove gradually decreases towards the bottom, making it easier for the tray body 3 to receive the pad 91 first, and then gradually slide to the bottom of the bearing part 32 under the guidance of the groove.

[0028] Please continue to refer to this. Figure 3 and Figure 4 A second cylinder 6 is fixedly connected to the side wall of each of the support crossbars 20. The piston rod end of the second cylinder 6 is connected to a pad block 61 with an L-shaped cross section. When the piston rod of the second cylinder 6 is not extended, the top of the pad block 61 is not higher than the top of the conveying support body 2.

[0029] The outside of the conveying support body 2 is also provided with a frame 8 whose internal width is greater than the width between the conveying support bodies 2 arranged side by side, and the bottom of the frame 8 is provided with a number of wheels 81.

[0030] Whenever the pad 91 is successfully placed on the surface of the conveyor belt 22, as the conveyor belt 22 moves continuously, several pads 91 will gradually move to the end of the conveyor support body 2, and fall into the interior of the frame 8 under the continuous drive of the conveyor belt 22. Since the number of pads 91 carried by the frame 8 is limited, and the clearance between several belt conveyors 1 is fixed, the clearance through which the clamped pads 91 pass is also fixed. Therefore, the position of the pads 91 on the surface of the conveyor belt 22 is also fixed. Thus, the conveyor belt 22 cannot be stopped, mainly to avoid affecting production efficiency. So, under the premise that the conveyor belt 22 is continuously conveying and the frame 8 can no longer carry the pads 91, the piston rod of the second cylinder 6 extends to drive the pad block 61 to move upward until it blocks the pads 91 conveyed by the subsequent conveyor belt 22.

[0031] Please continue to refer to this. Figure 4 Each of the pushing mechanisms 4 includes a cylinder support column 41, a first cylinder 42, and a photoelectric sensor 43. A cylinder support column 41 is installed on the side wall of each of the support seats 23. The cylinder body of each first cylinder 42 is fixedly connected to the cylinder support column 41, and the piston rod end of the first cylinder 42 is connected to the surface of the support part 31. The cylinder body of the first cylinder 42 is also provided with a photoelectric sensor 43 for monitoring whether there is a pad 91 inside the bearing part 32.

[0032] To reduce the time required for the gantry crane or robotic arm to pass through the clearance between several belt conveyors 1 and place the pad 91 on the surface of the conveyor belt 22, during the downward movement of the pads 91, the piston rod of the first cylinder 42 extends, thereby driving the pallet body 3 to slide upward until the inside of the bearing part 32 contacts the pad 91. At this time, the photoelectric sensor 43 detects the presence of the pad 91 inside the bearing part 32 and controls the piston rod of the first cylinder 42 to retract. As the piston rod of the first cylinder 42 continues to retract, the pad 91 inside the bearing part 32 will gradually be placed on the surface of the conveyor belt 22 and moved to the designated area under the conveyor belt 22.

[0033] Working principle and usage of this utility model: The clearance between several parallel belt conveyors 1 is greater than the width of the pad 91, but sufficient to support the profile 9.

[0034] When the clamping pad 91 of the gantry or robotic arm and the profile 9 on it are vertically lifted together, and then the profile 9 is placed back on the surface of the belt conveyor 1, the pad 91, because its width is less than the clearance gap, will fall out of the gap or continue to move downward under the clamping action, thereby achieving physical separation from the profile 9.

[0035] The lower conveyor support body 2 is provided with horizontal conveying power through the conveyor belt 22.

[0036] The pushing mechanism 4 (first cylinder 42) drives the pallet body 3 to move vertically and precisely along the guide rail 5 and the slider 51.

[0037] The photoelectric sensor 43 monitors in real time whether there is a pad 91 inside the support part 32 and feeds the signal back to the control system to control the extension and retraction of the first cylinder 42, so as to realize the automatic lifting and lowering cycle of the pallet body 3.

[0038] This design forms a buffer connection station: when the pallet body 3 rises, it can catch the falling pad 91 in advance, shortening the waiting time of the robotic arm; when it falls, it can smoothly transfer the pad 91 to the continuously running conveyor belt 22, realizing the overlap of the two processes of "discharging" and "conveying" in terms of time, which greatly improves the cycle efficiency.

[0039] The drive motor 71 drives the drive shaft 28 to rotate through the drive gear 72, metal chain and transmission gear 29, thereby driving all the pulleys 21 at one end.

[0040] Driven by the conveyor belt 22, the driven pulley 21 at the other end rotates synchronously, realizing the continuous linear motion of the conveyor belt 22, and the pad 91 bearing its surface moves in the specified direction.

[0041] The pad 91 is eventually conveyed to the end and falls into the movable frame 8 for centralized collection.

[0042] When the frame 8 is about to be fully loaded, the control system activates the second cylinder 6, causing its piston rod to extend and push the pad block 61 to rise to the blocking position.

[0043] The subsequently delivered pads 91 will be blocked by the raised pad block 61, preventing them from moving forward or falling, thus achieving temporary stacking without stopping the machine, while waiting for the staff to replace the empty frame 8.

[0044] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
