Description

Technical Field

[0001] This invention relates to the field of material conveying equipment technology, and more specifically, to a material buffer rack. Background Technology

[0002] Traditional material storage racks typically consist of a frame with several layers arranged from top to bottom, allowing materials to be stacked in layers. However, traditional racks lack material conveying capabilities, requiring manual handling. With technological advancements, material storage racks with conveyor belts have emerged. These conveyor belts can transport materials, but they often employ a waist-shaped (racetrack-shaped) design, and the drive shafts rotating the belts have a large diameter. This results in a large arc at the joint end of the conveyor belt, creating a large groove between the belt and other conveyor belts or equipment. Small materials can become stuck in this groove, preventing transport. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a material buffer rack with automatic material conveying function, which can reduce the occurrence of material jamming and is compatible with the transportation of more materials of different sizes.

[0004] To achieve the above objectives, the present invention provides a material buffer rack, comprising a frame open at the front and back. Inside the frame is a movable frame and a front-to-back movement drive device. The movable frame is slidably connected to the frame via linear guide rails. The front-to-back movement drive device is installed inside the frame and is drively connected to the movable frame, enabling the movable frame to move back and forth relative to the frame. The movable frame contains at least two docking conveyor mechanisms arranged sequentially from bottom to top at intervals. Each docking conveyor mechanism includes a belt mounting side plate, a conveyor belt, an electric roller, an upper rigid shaft at the docking end, a lower optical shaft at the docking end, a support roller module, and a support roller mounting beam. The conveyor belt, electric roller, upper rigid shaft at the docking end, lower optical shaft at the docking end, and support roller mounting beam are all installed between two parallel belt mounting side plates. The upper rigid shafts at the docking ends are located on the upper front and upper rear sides of the belt mounting side plate, respectively. The lower optical shafts at the docking ends are located on the lower front and lower rear sides of the belt mounting side plate, respectively. The diameter of the upper rigid shaft at the docking ends is smaller than the diameter of the lower optical shaft at the docking ends. The position of the upper rigid shaft at the docking ends protrudes outward from the lower optical shaft at the docking ends. The support roller module has several rollers that are installed on the inner side of the two upper rigid shafts at the docking ends via roller mounting beams. The support roller module is in rolling contact with the upper rigid shafts at the docking ends. The electric roller is located between the two lower optical shafts at the docking ends. The conveyor belt is fitted around the upper rigid shaft, the lower optical shaft, and the electric roller. The conveyor belt forms inverted trapezoidal blade end structures at both ends of the docking conveyor mechanism. The electric roller can drive the conveyor belt to rotate cyclically.

[0005] Preferably, the support roller module includes a roller seat, a first roller, and a second roller. One end of the roller seat is mounted on the roller mounting beam, the first roller is rotatably mounted on the other end of the roller seat, and the second roller is rotatably mounted on the top of the roller seat. The first roller and the second roller respectively roll in contact with the rigid shaft on the docking end, and the first roller, the second roller, and the rigid shaft on the docking end form a triangular arrangement.

[0006] Preferably, each docking conveyor also includes an upper guide optical shaft and a lower guide optical shaft installed between two belt mounting side plates. The upper guide optical shaft has several members and is arranged between the two docking end upper rigid shafts. The lower guide optical shaft is located between the docking end lower optical shaft and the electric roller.

[0007] Preferably, each docking conveyor also includes a driven wheel axle mounted on two belt mounting side plates, the driven wheel axle being located on the front and rear sides of the electric drum, the driven wheel bearing supporting the lower bottom of the conveyor belt.

[0008] Preferably, each docking conveyor mechanism further includes a docking detection device located in front of and / or behind the conveyor belt. The docking detection device includes a swing plate, a rotating screw, a contact swing shaft, a spring, a sensing plate, and a grooved photoelectric sensor. The swing plate is rotatably mounted on two belt mounting side plates via the rotating screw. The contact swing shaft is mounted between the lower ends of the two swing plates. The upper ends of the two swing plates are respectively connected to one end of the spring. The other end of the spring is hooked onto the belt mounting side plate. The sensing plate is mounted on the swing plate. The grooved photoelectric sensor is mounted on the belt mounting side plate. The contact swing shaft can swing up and down, and the grooved photoelectric sensor can detect the position of the sensing plate.

[0009] Preferably, the front and rear ends of the belt mounting side plate are respectively provided with material arrival detection sensors and / or matrix fiber optic sensors.

[0010] Preferably, a central guide baffle is provided above the center of each docking and conveying mechanism.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The present invention features a reasonable structural design and automatic material conveying function, which can reduce manual labor intensity, alleviate operator fatigue, facilitate operation, ensure safe and reliable equipment operation, and greatly improve production efficiency. Furthermore, the docking conveyor mechanism employs an upper rigid shaft and a lower smooth shaft at the docking end to restrict the shape of the conveyor belt at the front and rear docking ends. Simultaneously, the diameter of the upper rigid shaft is significantly reduced, and its position protrudes outward from the lower smooth shaft, thus forming inverted trapezoidal blade end structures at the front and rear ends of the conveyor belt. This reduces the depth and area of ​​the groove formed between the two docking conveyors when they are connected to docking conveyors of other machines, minimizing material jamming and allowing for the transport of materials of various sizes.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please refer to Figure 1 The present invention provides a material buffer rack, including a frame 1, a movable frame 2, a front and rear moving drive device 3, a docking conveyor mechanism 5, and other components. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, the frame 1 is a square frame structure with open front and back. The sides and bottom of the movable frame 2 can be slidably connected to the frame 1 via linear guide rails 4. The front and back moving drive device 3 is installed inside the frame 1 and is connected to the movable frame 2 for transmission. The front and back moving drive device 3 can drive the movable frame 2 to move back and forth relative to the frame 1.

[0028] Specifically, the forward and backward movement drive device 3 may include a motor 31, a reducer 32, a lead screw 33, and a nut seat 34. The motor 31 is connected to the reducer 32, the reducer 32 is connected to the lead screw 33, and the lead screw 33 is threadedly connected to the nut seat 34 installed at the bottom of the moving frame 2. The motor 31 can drive the moving frame 2 to move forward and backward through the lead screw 33 and the nut seat 34.

[0029] like Figure 1 , Figures 3 to 6As shown, the movable frame 2 is equipped with at least two docking conveyor mechanisms 5 arranged sequentially from bottom to top. Each docking conveyor mechanism 5 includes a belt mounting side plate 51, a conveyor belt 52, an electric roller 53, an upper rigid shaft 54 ​​at the docking end, a lower optical shaft 55 at the docking end, a support roller module 56, and a support roller mounting beam 57. The conveyor belt 52, electric roller 53, upper rigid shaft 54 ​​at the docking end, lower optical shaft 55 at the docking end, and support roller mounting beam 57 are all installed between two parallel belt mounting side plates 51. The upper rigid shaft 54 ​​at the docking end is located on the upper front and upper rear sides of the belt mounting side plate 51, respectively. The lower optical shafts 55 at the docking end are located at the lower front and lower rear sides of the belt mounting side plate 51, respectively. The diameter of the upper rigid shaft 54 ​​at the docking end is smaller than the diameter of the lower optical shaft 55 at the docking end. The position of the upper rigid shaft 54 ​​at the docking end protrudes outward from the lower optical shaft 55 at the docking end. The electric roller 53 is located between the two lower optical shafts 55 at the docking end. The conveyor belt 52 is fitted on the outside of the upper rigid shaft 54, the lower optical shaft 55 at the docking end, and the electric roller 53. The conveyor belt 52 forms an inverted trapezoidal blade end structure at the front and rear ends of the docking conveyor mechanism 5. The electric roller 53 can drive the conveyor belt 52 to rotate cyclically.

[0030] Since the conveyor belt 52 of the docking conveyor mechanism 5 is driven to rotate by the electric roller 53 located in the middle, the diameter of the rigid shaft 54 ​​at the docking end is not restricted and can be set to be thinner. Compared with the conventional conveyor belt drive structure, the docking conveyor mechanism of this embodiment does not require a motor and a large-diameter drive shaft to drive the conveyor belt.

[0031] like Figures 5 to 7 As shown, the support roller module 56 has several rollers mounted on the inner sides of the two mating ends of the rigid shaft 54 ​​via roller mounting beams 57. The support roller module 56 rolls in contact with the mating ends of the rigid shaft 54. In this embodiment, the support roller module 56 can support the mating ends of the rigid shaft 54, extending the service life of the mating ends of the rigid shaft 54, thus allowing the diameter of the mating ends of the rigid shaft 54 ​​to be set smaller.

[0032] Specifically, the support roller module 56 may include a roller seat 561, a first roller 562, and a second roller 563. One end of the roller seat 561 is mounted on the roller mounting beam 57. The first roller 562 is rotatably mounted on the other end of the roller seat 561, and the second roller 563 is rotatably mounted on the top of the roller seat 561. The first roller 562 and the second roller 563 respectively roll in contact with the rigid shaft 54 ​​on the docking end. The first roller 562 and the second roller 563 can form a triangular arrangement with the rigid shaft 54 ​​on the docking end. This arrangement can improve the support effect on the rigid shaft 54 ​​on the docking end.

[0033] like Figure 4 and Figure 5As shown, each docking conveyor 5 may also include an upper guide optical shaft 510 and a lower guide optical shaft 511 installed between two belt mounting side plates 51. The upper guide optical shaft 510 is provided with several shafts and arranged between two docking end upper rigid shafts 54. The lower guide optical shaft 511 is located between the docking end lower optical shaft 55 and the electric roller 53.

[0034] like Figure 4 and Figure 5 As shown, each docking conveyor mechanism 5 may also include a driven wheel shaft 58 mounted on two belt mounting side plates 51. The driven wheel shaft 58 is located on the front and rear sides of the electric roller 53, and supports the lower bottom of the conveyor belt 52. The driven wheel shaft 58 can cooperate with the electric roller 53 to allow the electric roller 53 to drive the conveyor belt 52 more effectively.

[0035] like Figure 3 and Figure 8 As shown, each docking conveyor mechanism 5 may also include a docking detection device 59, which is located in front of and / or behind the conveyor belt 52. Specifically, the docking detection device 59 may include a swing plate 591, a rotating screw 592, a contact swing shaft 593, a spring 594, a sensing plate 595, and a slotted photoelectric sensor 596. The swing plate 591 is rotatably mounted on two belt mounting side plates 51 by the rotating screw 592. The contact swing shaft 593 is mounted between the lower ends of the two swing plates 591. The upper ends of the two swing plates 591 are respectively connected to one end of the spring 594. The other end of the spring 594 is hooked on the belt mounting side plate 51. The sensing plate 595 is mounted on the swing plate 591. The slotted photoelectric sensor 596 is mounted on the belt mounting side plate 51. The contact swing shaft 593 can swing up and down, and the slotted photoelectric sensor 596 can detect the position of the sensing plate 595.

[0036] When the docking conveyor 5 approaches and docks with the docking conveyor of another machine, the contact swing shaft 593 will be pressured and pressed down to the bottom of the docking end of the docking conveyor. At this time, the sensing plate 595 can swing with the swing plate 591. When the sensing plate 595 swings into the slot of the slot-shaped photoelectric sensor 596, it is determined that the docking conveyor 5 has completed the docking with the docking conveyor of another machine.

[0037] like Figure 3 As shown, the front and rear ends of the belt mounting side plate 51 can also be equipped with a material arrival detection sensor 512 and a matrix fiber optic sensor 513, respectively.

[0038] like Figure 1 As shown, each docking conveyor 5 may also be provided with a central guide partition 6 above its center. The central guide partition 6 can divide the docking conveyor 5 into left and right sections.

[0039] like Figure 1 As shown, the frame 1 may also be equipped with a recycling conveying mechanism 7, which may be located above the docking conveying mechanism 5. The conveying direction of the recycling conveying mechanism 7 is opposite to that of the docking conveying mechanism 5. In this embodiment, preferably, the recycling conveying mechanism 7 may also include components such as a belt mounting side plate 51, a conveyor belt 52, an electric roller 53, a docking end upper rigid shaft 54, a docking end lower optical shaft 55, a support roller module 56, and a support roller mounting beam 57, the structure of which is mostly the same as that of the docking conveying mechanism 5.

[0040] like Figure 1 As shown, the frame 1 can also be equipped with a control box 8 and a wireless power supply 9. The control box 8 can supply power and control the motor of the forward and backward movement drive device 3, the electric roller of the docking conveyor mechanism 5, and other electrical components. The wireless power supply 9 can interface with wireless power supplies of other machines.

[0041] like Figure 1 As shown, the frame 1 may also be equipped with an emergency stop button 10 and a tri-color light 11 on its exterior, which can improve the safety performance of the equipment. In addition, the bottom of the frame 1 may be equipped with adjustable support feet 12 and / or casters 13.

[0042] In summary, the present invention has a reasonable structural design, automatic material conveying function, reduces manual labor intensity, alleviates operator fatigue, is easy to operate, and is safe and reliable in operation, greatly improving production efficiency. Furthermore, the docking conveyor mechanism uses a combination of an upper rigid shaft and a lower smooth shaft at the docking end to restrict the shape of the conveyor belt at the front and rear docking ends. Simultaneously, the diameter of the upper rigid shaft is significantly reduced, and its position protrudes outward from the lower smooth shaft, thus forming inverted trapezoidal blade end structures at the front and rear ends of the conveyor belt. This reduces the depth and area of ​​the groove formed between the two docking conveyors when they are connected to docking conveyors of other machines, minimizing material jamming and allowing for the transport of materials of various sizes.

[0043] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
