Description

Technical Field

[0001] This utility model relates to the field of automation equipment, and in particular to a dual material handling device based on a single power source. Background Technology

[0002] In the large-scale production process of tissue packaging, the feeding mechanism is a key link connecting material storage and subsequent processing steps (such as folding, sealing, and forming). Its core responsibility is to accurately transport the tissue packaging intermediate to the next work station according to the set rhythm. Its operating efficiency and reliability directly determine the production capacity stability and continuous operation capability of the entire production line. Currently, the feeding mechanisms of mainstream tissue packaging production lines on the market generally adopt a structural design mode of "single power source driving single feeding mechanism". In this mode, a single power source (such as a servo motor or cylinder) drives only one set of feeding components (including feeding claws, transmission rollers and other actuators), forming a "one-to-one" power-execution matching relationship. From the perspective of production efficiency, this design has significant limitations: since a single feeding mechanism can only complete the separation and conveying of one set of materials at a time, when the production line needs to increase capacity and speed up the material flow, the processing capacity of a single mechanism will directly become a bottleneck. For example, during the peak period of tissue packaging, the supply speed of stacked materials is accelerated, and the single feeding mechanism is unable to increase its processing efficiency in sync, which can easily lead to material accumulation and conveying delays, making it difficult for the operating efficiency of the entire production line to match the actual production needs.

[0022] Please see Figures 1-6 The embodiments of this utility model include: A dual material handling device based on a single power source includes: a frame 1, a cover plate 2 disposed on the top of the frame 1, a horizontal transmission mechanism disposed on the frame 1 below the cover plate 2, and a pair of material handling mechanisms; the horizontal transmission mechanism is disposed at the middle position of the frame 1; the pair of material handling mechanisms are centrally symmetrically disposed on both sides of the horizontal transmission mechanism about the center of the horizontal transmission mechanism; the top of each of the two material handling mechanisms is connected to a vertically upward material handling end, and the two material handling mechanisms are respectively connected to the two sides of the horizontal transmission mechanism; the cover plate 2 has a material handling channel 3 that runs vertically through the cover plate 2 and avoids the material handling ends along the length of the cover plate 2; under the action of a single power source, i.e., a single horizontal transmission mechanism, the two material handling mechanisms are controlled to move synchronously away from each other in the horizontal direction; during the displacement process, each material handling mechanism controls the vertical lifting and lowering of the connected material handling end, thereby completing the corresponding material handling action, and the action processes of the two material handling mechanisms do not interfere with each other.

[0023] As a preferred embodiment of this utility model, such as Figures 1-3As shown, the horizontal transmission mechanism includes: a support plate 4, a synchronous belt 5, a main synchronous pulley 6, a driven synchronous pulley 7, and a drive motor 8. The support plate 4 is strip-shaped and horizontally arranged on the frame 1 near the bottom of the frame 1 along the length of the cover plate 2. The front and rear ends of the support plate 4 are connected to the two sides of the frame 1, respectively. The main synchronous pulley 6 and the driven synchronous pulley 7 are horizontally and rotatably arranged at both ends of the upper surface of the support plate 4, and the synchronous belt 5 is driven and sleeved on the main synchronous pulley 6 and the driven synchronous pulley 7. In a specific example, the support plate 4 has through holes that vertically penetrate the support plate 4 and correspond to the main synchronous pulley 6 and the driven synchronous pulley 7, respectively. The through hole corresponding to the main synchronous pulley 6 is a second clearance hole, in which a rotating shaft seat is embedded. The drive motor 8 is vertically arranged on the support plate 4. Below, corresponding to the position of the second clearance hole, the fixed end of the drive motor 8 is connected to the lower surface of the support plate 4. The output shaft of the drive motor 8 is vertically upward and passes through the rotating shaft seat, and also passes through the second clearance hole. The main synchronous pulley 6 is keyed to the upper end of the output shaft of the drive motor 8 and can rotate with the rotation of the main rotating shaft. That is, the drive motor 8 drives the main synchronous pulley 6 to rotate around the output shaft as the central axis. The through hole corresponding to the slave synchronous pulley 7 is the first clearance hole. A rotating shaft is fixed in the first clearance hole. A bearing seat is sleeved on the rotating shaft corresponding to the position of the slave synchronous pulley 7. The slave synchronous pulley 7 is horizontally rotatably sleeved on the bearing seat corresponding to the main synchronous pulley 6. When the drive motor 8 is operating, it drives the main synchronous pulley 6 to rotate, the main synchronous pulley 6 drives the synchronous belt 5 to rotate, and the synchronous belt 5 drives the slave synchronous pulley 7 to rotate.

[0024] As a preferred embodiment of this utility model, such as Figures 2-6As shown, each material feeding mechanism includes: a horizontal slide rail 9, a slider 10, a lifting cylinder 11, a horizontal mounting plate 12, and eight feeding rods 13 arranged side by side on the upper surface of the horizontal mounting plate 12 (the horizontal mounting plate 12 and the feeding rods 13 together form the feeding end, so there are also eight feeding channels 3); the horizontal slide rail 9 is parallel to the support plate 4 and is set on the frame 1 on the left or right side of the support plate 4, and the horizontal slide rail 9 is located below the support plate 4; the slider 10 is slidably set on the horizontal slide rail 9; in order to improve stability, a cylinder mounting bracket 14 is set on the upper surface of the slider 10, the lifting cylinder 11 is vertically set on one side of the cylinder mounting bracket 14 and corresponds to the position of the feeding channel 3, and a limiting slide rail 15 is set on the other side of the cylinder mounting bracket 14 along the length direction of the lifting cylinder 11, and a limiting slide rail 15 is slidably set on the limiting slide rail 15. Block 16; To connect to the feeding end, the piston rod end of the lifting cylinder 11 is connected to an L-shaped limiting member 17. The horizontal part of the L-shaped limiting member 17 is connected to the piston rod of the lifting cylinder 11, and the vertical part of the L-shaped limiting member 17 is connected to one side of the limiting slider 16. The horizontal mounting plate 12 is horizontally connected to the upper surface of the horizontal part of the L-shaped limiting member 17. Several feeding rods 13 are all vertically upward. To connect to the power source, a horizontally arranged connecting plate 18 is connected to the cylinder mounting bracket 14 near the synchronous belt 5. The front end of the connecting plate 18 extends horizontally above the synchronous belt 5, and the lower surface of the front end of the connecting plate 18 is connected to the synchronous belt 5 through a clamping plate 19. This connection allows the lifting cylinder 11 to slide along the horizontal slide rail 9 under the action of the synchronous belt 5 when the synchronous belt 5 is in operation. When the lifting cylinder 11 is in operation, it controls the feeding rods 13 connected to it to move in the vertical direction.

[0025] As a preferred embodiment of this utility model, such as Figure 6 As shown, the cover plate 2 is provided with eight material feeding channels 3 corresponding to the eight material feeding rods 13 of the two material feeding mechanisms; the eight material feeding channels 3 are parallel to each other and arranged side by side.

[0026] In a preferred embodiment of this utility model, in order to operate alternately without motion interference, one of the two material-grabbing mechanisms is located near the main synchronous wheel 6, and the other is located near the slave synchronous wheel 7. The two material-grabbing mechanisms form a centrally symmetrical shape about the center position of the support plate 4.

[0027] As a preferred embodiment of this utility model, such as Figure 2As shown, the operating principle of this device is as follows: This device is usually set below the material that needs to be unloaded. When unloading is required, the drive motor 8 starts to operate, and the operating mode is forward rotation + reverse rotation (synchronous belt 5 rotates clockwise + synchronous belt 5 rotates counterclockwise), and it cycles continuously. If the drive motor 8 is initially rotating forward, the lifting cylinder 11 of the unloading mechanism on the right side of the synchronous belt 5 controls its connected unloading rod 13 to rise and pass through the unloading channel 3, while the lifting cylinder 11 of the unloading mechanism on the left side of the synchronous belt 5 controls its connected unloading rod 13 to descend and move away from the unloading channel 3 and another unloading mechanism. During the forward rotation of the drive motor 8, the synchronous belt 5 rotates clockwise. During the forward rotation, the drive motor 8 drives the main synchronous pulley 6 to rotate, and the synchronous pulley 7 cooperates with the main synchronous pulley 6 to make the synchronous belt 5 rotate clockwise. During the clockwise rotation of the synchronous belt 5, it drives the unloading mechanism on its right side to move in direction A, and at the same time drives the unloading mechanism on its left side to move in direction B. The unloading rod 13 of the unloading mechanism on the right side of the synchronous belt 5 completes one movement in direction A during this process. The material-picking action: After the drive motor 8 rotates forward, it begins to reverse. At this time, the lifting cylinder 11 of the material-picking mechanism on the right side of the synchronous belt 5 controls the material-picking rod 13 connected to it to descend away from the material-picking channel 3 and another material-picking mechanism. The lifting cylinder 11 of the material-picking mechanism on the left side of the synchronous belt 5 controls the material-picking rod 13 connected to it to rise and pass through the material-picking channel 3. During the reverse rotation of the drive motor 8, the synchronous belt 5 rotates counterclockwise. During the reverse rotation, the drive motor 8 drives the main synchronous pulley 6 to rotate, and the synchronous pulley 7 cooperates with the main synchronous pulley 6 to make the synchronous belt 5 rotate counterclockwise. During the counterclockwise rotation of the synchronous belt 5, it drives the material-picking mechanism on its right side to move in direction B, and at the same time drives the material-picking mechanism on its left side to move in direction A. The material-picking rod 13 of the material-picking mechanism on the left side of the synchronous belt 5 completes one material-picking action in direction A during this process. At this time, the two material-picking structures return to their initial positions and complete the reset. At this point, one material-picking control ends. Under the forward and reverse action of the drive motor 8, the two material-picking mechanisms complete two material-picking actions in the same direction, which greatly improves the material-picking efficiency.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
