Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, and in particular to a dual-station material loading system and a dual-station material loading method. Background Technology

[0002] A material palletizing system and method with application number 202310159841.6 is disclosed, which includes a material conveying device. The material conveying device includes a material input mechanism and a material conveying mechanism arranged in sequence. An inclined palletizing device is provided on one side of the material conveying mechanism. The material conveying mechanism is provided with multiple sets of material conveying components and a detection mechanism. The material conveying components are provided with multiple material placement parts. The detection mechanism is used to detect whether there is missing material in the material placement parts. The inclined palletizing device is connected to at least one set of material conveying components. A material return mechanism is provided between the material input mechanism and the material conveying mechanism for returning the material on the material conveying component with missing material to the material input mechanism. The dual-station material loading system has the following shortcomings: 1) In single-station loading, after a tray is full, it is necessary to wait for an empty tray to be input for replacement before loading can proceed again. This waiting time reduces the cycle time and production efficiency of the equipment; 2) The material conveying mechanism vertically transports the bottles to the inclined loading mechanism, which then transfers them. The vertical transfer of the bottles makes it difficult for the inclined loading mechanism to pick them up, and gaps can easily appear between the bottles, causing bottles to leak when the suction cups pick them up later, thus affecting the loading process; 3) The inclined loading mechanism is not specific enough. It generally includes a suction nozzle structure arranged side by side, with each nozzle fixed in a row. This makes it difficult to adapt to the narrow opening of the old-style sterilization trays and to meet the loading requirements when the number of bottles changes (e.g., the number of bottles in the row changes from even to odd); 4) The overall structure is complex and requires a material conveying mechanism such as a magnetic levitation structure to achieve loading, resulting in high costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a material dual-station palletizing system and material dual-station palletizing method that saves pallet changing waiting time and improves system cycle time and production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A dual-station material loading system includes a material supply device, a material loading device, and an upper and lower tray conveying mechanism arranged vertically. A first lifting and fixing tray mechanism, a second fixing tray mechanism, and a lifting and transferring mechanism are arranged sequentially along the tray conveying mechanism between the upper and lower tray conveying mechanisms. The material loading device is used to load the material supplied by the material supply device onto the trays on the first lifting and fixing tray mechanism and the second fixing tray mechanism. The lifting and transferring mechanism is used to move the trays between the upper tray conveying mechanism, the lower tray conveying mechanism, and the second fixing tray mechanism.

[0006] As a further improvement to the above technical solution:

[0007] The second plate-fixing mechanism is liftable, or the second plate-fixing mechanism includes a plate-fixing layer flush with the upper plate-transferring mechanism and a filter layer flush with the lower plate-transferring mechanism.

[0008] The first lifting and fixing plate mechanism and the second fixing plate mechanism both include a lifting component, a conveying plate component disposed on the lifting component, and a fixing plate component and a plate door opening and closing component disposed on the conveying plate component.

[0009] The material supply device includes an input device and a material conveying device. The material conveying device includes a vertical-to-horizontal mechanism and a horizontal material conveying mechanism. The vertical-to-horizontal mechanism is located between the material input device and the horizontal material conveying mechanism and is used to convert the vertical material conveyed by the material input device into a horizontal material and convey it to the horizontal material conveying mechanism. The material loading device is located on one side of the horizontal material conveying mechanism.

[0010] The vertical-to-horizontal mechanism includes a conveying auger and a tilting conveyor, and the material input device, conveying auger, tilting conveyor and horizontal material conveying mechanism are connected in sequence.

[0011] The horizontal material conveying mechanism includes a horizontal material conveyor belt and a baffle plate above the horizontal material conveyor belt. The horizontal material conveyor belt is connected to a laying and twisting track, and the material loading device is located on one side of the horizontal material conveyor belt.

[0012] The horizontal material conveying mechanism has a transition platform on one side of the discharge end for placing materials to be picked up by the material loading device, and a pushing mechanism on the other side for pushing the materials at the discharge end of the horizontal material conveying mechanism in rows onto the transition platform.

[0013] The pushing mechanism includes a row of pushing components arranged side by side and a single pushing component. The horizontal material conveying mechanism has a quantity detection mechanism for detecting the amount of material passing through it upstream of the pushing mechanism.

[0014] The material loading device includes a loading and transfer mechanism and a fixed suction component. The fixed suction component is mounted on the loading and transfer mechanism, which is located on one side of the horizontal material conveying mechanism. The loading and transfer mechanism has movable suction components at both ends of the fixed suction component that can rotate to the rear of the fixed suction component.

[0015] A method for loading materials at two stations, using the aforementioned two-station material loading system, includes the following steps:

[0016] Feeding the tray: The tray body is input by the lower tray conveying mechanism, and then selectively aligned with the upper and lower tray conveying mechanisms through the first lifting and fixing tray mechanism and the lifting and transfer mechanism, so that the empty tray body enters the first lifting and fixing tray mechanism and the second fixing tray mechanism;

[0017] Loading: At least one of the first lifting and fixing plate mechanism and the second fixing plate mechanism is in a position flush with the upper conveying plate mechanism, and the material loading device loads the material.

[0018] Discharge: The first lifting and fixing mechanism and the lifting and transferring mechanism selectively align with the upper and lower conveying mechanisms, allowing the tray containing the material to be discharged by the upper conveying mechanism.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] The material dual-station palletizing system of the present invention realizes palletizing at two palletizing stations (dual-station palletizing) through a first lifting and fixing mechanism and a lifting and transferring mechanism. The lifting and lowering settings of the first lifting and fixing mechanism and the lifting and transferring mechanism ensure that at least one fixing mechanism at the two palletizing stations has a pallet in place for palletizing, and make pallet feeding and pallet discharge proceed smoothly, saving pallet changing waiting time and improving system cycle time and production efficiency.

[0021] The material dual-station palletizing method of the present invention realizes palletizing at two palletizing stations through a first lifting and fixing mechanism and a lifting and transferring mechanism (dual-station palletizing). Through the lifting and lowering settings of the first lifting and fixing mechanism and the lifting and transferring mechanism, it is ensured that at least one fixing mechanism at the two palletizing stations has a pallet fixed for palletizing, and the pallet entering and exiting are carried out smoothly, saving pallet changing waiting time and improving system cycle time and production efficiency.

[0039] Example 1:

[0040] Figures 1 to 10 This invention illustrates a first embodiment (Embodiment 1) of the material dual-station palletizing system. The material dual-station palletizing system of this embodiment includes a material supply device, a material palletizing device 3, and an upper pallet conveying mechanism 4 and a lower pallet conveying mechanism 5 arranged vertically. Between the upper pallet conveying mechanism 4 and the lower pallet conveying mechanism 5, there is a first lifting and fixing pallet mechanism 6, a second fixing pallet mechanism 7, and a lifting and transfer mechanism 8 arranged sequentially along the pallet conveying mechanism. The material palletizing device 3 is used to load the material conveyed by the material supply device onto the pallet body 9 on the first lifting and fixing pallet mechanism 6 and the second fixing pallet mechanism 7. The lifting and transfer mechanism 8 is used to move the pallet body 9 between the upper pallet conveying mechanism 4, the lower pallet conveying mechanism 5, and the second fixing pallet mechanism 7.

[0041] The working process of the material dual-station palletizing system in this embodiment is as follows: First, the pallet 9 is input by the lower pallet conveying mechanism 5, and then selectively aligned with the upper pallet conveying mechanism 4 and the lower pallet conveying mechanism 5 by the first lifting and fixing mechanism 6 and the lifting and transferring mechanism 8, so that the empty pallet 9 enters the first lifting and fixing mechanism 6 and the second fixing mechanism 7; Second, at least one of the first lifting and fixing mechanism 6 and the second fixing mechanism 7 is aligned with the upper pallet conveying mechanism 4, and material is loaded into it by the material palletizing device 3; Third, the first lifting and fixing mechanism 6 and the lifting and transferring mechanism 8 are selectively aligned with the upper pallet conveying mechanism 4 and the lower pallet conveying mechanism 5, so that the pallet 9 containing material enters the upper pallet conveying mechanism 4 for output. This dual-station palletizing system achieves palletizing at two palletizing stations through a first lifting and fixing mechanism 6 and a lifting and transfer mechanism 8 (dual-station palletizing). The lifting and lowering settings of the first lifting and fixing mechanism 6 and the lifting and transfer mechanism 8 ensure that at least one fixing mechanism at each of the two palletizing stations has a pallet 9 in place for palletizing, and that pallet entry and exit proceed smoothly, saving pallet change waiting time and improving system cycle time and production efficiency.

[0042] Example 2:

[0043] Figures 1 to 10 A second embodiment (Embodiment 2) of the material dual-station palletizing system of the present invention is also shown, which is further improved on the basis of Embodiment 1 as follows:

[0044] In this embodiment, the second stabilizing mechanism 7 is liftable.

[0045] The working process of the dual-station material loading system in this embodiment is as follows: First, the tray 9 is input by the lower tray conveying mechanism 5, and then selectively aligned with the upper tray conveying mechanism 4 and the lower tray conveying mechanism 5 by the first lifting and fixing mechanism 6, the second fixing mechanism 7, and the lifting and transfer mechanism 8, so that the empty tray 9 enters the first lifting and fixing mechanism 6 and the second fixing mechanism 7; Second, at least one of the first lifting and fixing mechanisms 6 and the second fixing mechanism 7 is aligned with the upper tray conveying mechanism 4, and material is loaded into it by the material loading device 3; Third, the first lifting and fixing mechanism 6, the second fixing mechanism 7, and the lifting and transfer mechanism 8 are selectively aligned with the upper tray conveying mechanism 4 and the lower tray conveying mechanism 5, so that the tray 9 containing material enters the upper tray conveying mechanism 4 for output. This dual-station material loading system ensures smooth tray entry and exit between the two loading stations through the lifting and lowering configuration of the first lifting and fixing mechanism 6, the second fixing mechanism 7, and the lifting and transfer mechanism 8.

[0046] Furthermore, such as Figure 3 and Figure 4As shown, in this embodiment, both the first lifting and fixing plate mechanism 6 and the second fixing plate mechanism 7 include a lifting component 61, a plate conveying component 62 disposed on the lifting component 61, a fixing plate component 63 disposed on the plate conveying component 62, and a plate door opening and closing component 64. After the plate body 9 enters the plate conveying component 62, it is locked by the fixing plate component 63, and the plate door is opened by the plate door opening and closing component 64 before loading. When unloading, the fixing plate component 63 releases the lock on the plate body 9, and the plate door opening and closing component 64 closes the plate door. The lifting component 61 drives the plate conveying component 62 to move up and down, achieving alternating alignment with the upper plate conveying mechanism 4 and the lower plate conveying mechanism 5, in preparation for loading, unloading, and unloading. The plate conveying component 62 has a conveying function for the plate body 9, which can assist in unloading and unloading.

[0047] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the material supply device includes an input device 1 and a material conveying device 2. The material conveying device 2 includes a vertical-to-horizontal mechanism 21 and a horizontal material conveying mechanism 22. The vertical-to-horizontal mechanism 21 is located between the material input device 1 and the horizontal material conveying mechanism 22, and is used to convert the vertical material conveyed by the material input device 1 into a horizontal material and convey it to the horizontal material conveying mechanism 22. The material loading device 3 is located on one side of the horizontal material conveying mechanism 22. The input device 1 inputs material (such as a cylindrical container) into the vertical-to-horizontal mechanism 21. The vertical-to-horizontal mechanism 21 converts the vertical material conveyed by the material input device 1 into a horizontal material and conveys it to the horizontal material conveying mechanism 22. The horizontal material conveying mechanism 22 conveys the horizontal material forward to one side of the material loading device 3 for loading onto the tray. The material conveying device 2 makes the material horizontally conveyed to one side of the material loading device 3, which is convenient for the material loading device 3 to load onto the tray. The material rolls closely together under the horizontal device, making it less likely for gaps to appear and preventing bottle leakage during loading.

[0048] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the vertical-to-horizontal mechanism 21 includes a conveying auger 211 and a tilting conduit 212. The material input device 1, the conveying auger 211, the tilting conduit 212, and the horizontal material conveying mechanism 22 are sequentially connected. Vertical materials are conveyed forward by the conveying auger 211. During the process of passing through the tilting conduit 212, the materials are tilted and placed horizontally under the guiding action of the tilting conduit 212, enabling the horizontal material conveying mechanism 22 to feed the horizontal materials. The overall structure is simple, the layout is ingenious, and the cost is low.

[0049] Furthermore, such as Figure 5As shown, in this embodiment, the horizontal material conveying mechanism 22 includes a horizontal material conveyor belt 221 and a baffle plate 222 above the horizontal material conveyor belt 221. The horizontal material conveyor belt 221 is connected to a tilting chute 212, and the material loading device 3 is located on one side of the horizontal material conveyor belt 221. The conveying auger 211 drives the material forward and places the upright material horizontally through the tilting chute 212. The horizontally placed material continues to move forward onto the horizontal material conveyor belt 221. The baffle plate 222 is used to block the material above the horizontal material conveyor belt 221 to prevent material stacking. Preferably, the baffle plate 222 is adjustable up and down to accommodate materials of different sizes, and in actual use, it should be 0.5-1mm away from the upper surface of the material. Further, the material is a cylindrical bottle.

[0050] Furthermore, in this embodiment, a transition platform 23 for placing materials to be picked up by the material loading device 3 is provided on one side of the discharge end of the horizontal material conveying mechanism 22, and a pushing mechanism 24 is provided on the other side. The pushing mechanism 24 is used to push the materials at the discharge end of the horizontal material conveying mechanism 22 in rows onto the transition platform 23.

[0051] Furthermore, in this embodiment, the pushing mechanism 24 includes a row of pushing components 241 arranged side by side and a single pushing component 242. The horizontal material conveying mechanism 22 is provided with a quantity detection mechanism 25 for detecting the amount of material passing through upstream of the pushing mechanism 24. Specifically, the horizontal material conveyor belt 221 is provided with a quantity detection mechanism 25 for detecting the amount of material passing through upstream of the pushing mechanism 24, and a baffle plate is provided at the end of the horizontal material conveyor belt 221.

[0052] The material stops moving due to the obstruction of the baffle plate at the end of the horizontal material conveyor belt 221. After the upstream quantity detection mechanism 25 detects the required quantity of material, the row of pushing components 241 and the individual pushing components 242 move simultaneously to push the entire row of material forward onto the transition platform 23. The material loading device 3 then loads the material onto the transition platform 23. If the material loading device 3 needs to take one less container, the individual pushing component 242 does not move forward, thus satisfying the pushing requirements for quantity changes (such as changing the material quantity from even to odd).

[0053] Furthermore, such as Figures 6 to 10 As shown, in this embodiment, the material loading device 3 includes a loading and transfer mechanism 31 and a fixed suction component 32. The fixed suction component 32 is disposed on the loading and transfer mechanism 31. The loading and transfer mechanism 31 is located on one side of the horizontal material conveying mechanism 22. The loading and transfer mechanism 31 has movable suction components 33 that can rotate to the rear side of the fixed suction component 32 at both ends of the fixed suction component 32.

[0054] like Figure 8As shown, when material is being picked up on the transition platform 23, the movable suction component 33 faces forward and is arranged side by side with the fixed suction component 32, achieving the sequential picking up of material. Figure 9 As shown, before entering the tray 9, the movable suction assembly 33 rotates to the rear of the fixed suction assembly 32 to reduce the overall length of the tray transfer mechanism 31 and adapt to the narrow tray opening. After entering the tray 9, as... Figure 10 As shown, the movable suction assembly 33 rotates back to its forward position, restoring the materials to be placed side by side. Furthermore, each movable suction assembly 33 is driven independently and can be selectively used or not used to meet the tray loading requirements when the number of containers in the placement row changes (e.g., from an even number to an odd number).

[0055] Furthermore, the lifting assembly 61 is equipped with a tilting assembly that enables the tray conveying assembly 62 to tilt.

[0056] Example 3:

[0057] The third embodiment (Embodiment 3) of the material dual-station palletizing system of the present invention has a structure that is basically the same as that of Embodiment 2, except that the second pallet fixing mechanism 7 is not movable, but includes a pallet fixing layer flush with the upper pallet conveying mechanism 4 and a filter layer flush with the lower pallet conveying mechanism 5. That is, the pallet fixing layer is provided with a pallet conveying component 62 and a pallet fixing component 63 provided on the pallet conveying component 62. The pallet conveying component 62 is flush with the upper pallet conveying mechanism 4 and does not move. This reduces the difficulty of setting up the second pallet fixing mechanism 7.

[0058] Example 4:

[0059] Figure 11 This paper illustrates a fourth embodiment of the material dual-station palletizing method of the present invention. This embodiment uses the material dual-station palletizing system of Embodiment 1 and includes the following steps:

[0060] Feeding the tray: The tray body 9 is input by the lower tray conveying mechanism 5, and then selectively aligned with the upper tray conveying mechanism 4 and the lower tray conveying mechanism 5 through the first lifting and fixing tray mechanism 6 and the lifting and transferring mechanism 8, so that the empty tray body 9 enters the first lifting and fixing tray mechanism 6 and the second fixing tray mechanism 7.

[0061] Loading: At least one of the first lifting and fixing plate mechanism 6 and the second fixing plate mechanism 7 is in a position flush with the upper plate conveying mechanism 4, and the material loading device 3 loads the material.

[0062] Discharge: The first lifting and fixing mechanism 6 and the lifting and transfer mechanism 8 selectively align with the upper conveying mechanism 4 and the lower conveying mechanism 5, so that the tray 9 containing the material enters the upper conveying mechanism 4 for output.

[0063] This dual-station palletizing method achieves palletizing at two stations through a first lifting and fixing mechanism 6 and a lifting and transfer mechanism 8 (dual-station palletizing). The lifting and lowering settings of the first lifting and fixing mechanism 6 and the lifting and transfer mechanism 8 ensure that at least one fixing mechanism at each of the two palletizing stations has a pallet 9 in place for palletizing, and that pallet entry and exit proceed smoothly, saving pallet changing waiting time and improving system cycle time and production efficiency.

[0064] Example 5:

[0065] Figure 11 A fifth embodiment of the material dual-station palletizing method of the present invention is also shown. The material dual-station palletizing method of this embodiment adopts the material dual-station palletizing system of embodiment two and includes the following steps:

[0066] S1. Plate feeding: Plate 9 is input by the lower plate feeding mechanism 5, and then selectively aligned with the upper plate feeding mechanism 4 and the lower plate feeding mechanism 5 through the first lifting and fixing plate mechanism 6, the second fixing plate mechanism 7 and the lifting and transfer mechanism 8, so that the empty plate 9 enters the first lifting and fixing plate mechanism 6 and the second fixing plate mechanism 7.

[0067] S2, loading: At least one of the first lifting and fixing plate mechanism 6 and the second fixing plate mechanism 7 is in a position flush with the upper plate conveying mechanism 4, and the material loading device 3 loads the material.

[0068] S3, Discharge: The first lifting and fixing mechanism 6, the second fixing mechanism 7 and the lifting and transfer mechanism 8 selectively align with the upper conveying mechanism 4 and the lower conveying mechanism 5, so that the tray 9 containing the material enters the upper conveying mechanism 4 for output.

[0069] Furthermore, the tray loading process is as follows: First, the first lifting and fixing tray mechanism 6, the second fixing tray mechanism 7, and the lifting and transfer mechanism 8 are all aligned with the lower tray conveying mechanism 5. Second, the empty tray is successively conveyed to the first lifting and fixing tray mechanism 6 and the second fixing tray mechanism 7 through the lower tray conveying mechanism 5. Then, the first lifting and fixing tray mechanism 6 and the second fixing tray mechanism 7 rise successively to align with the upper tray conveying mechanism 4 and reach the tray loading station.

[0070] The material loading process: The material loading device 3 loads the material into the trays 9 on the first lifting and fixing mechanism 6 and the second fixing mechanism 7 in sequence;

[0071] Discharge process: First, the first lifting and fixing plate mechanism 6 and the lifting and transferring mechanism 8 descend to align with the lower plate conveying mechanism 5. The plate 9 containing material on the first lifting and fixing plate mechanism 6 is conveyed to the lifting and transferring mechanism 8. The lifting and transferring mechanism 8 then rises to align with the upper plate conveying mechanism 4, and the plate 9 containing material on the lifting and transferring mechanism 8 is output through the upper plate conveying mechanism 4. Second, the lifting and transferring mechanism 8 descends to align with the lower plate conveying mechanism 5, allowing the empty plate on the lower plate conveying mechanism 5 to be transferred to the first lifting and fixing plate mechanism 6. The first lifting and fixing plate mechanism 6 then rises to align with the upper plate conveying mechanism 5. The upper tray conveying mechanism 4 is aligned with the lower tray conveying mechanism 5. The empty tray is then conveyed to the first tray loading station for loading. The lifting and transfer mechanism 8 then rises to align with the upper tray conveying mechanism 4. The tray 9 containing material on the second tray fixing mechanism 7 is transferred to the upper tray conveying mechanism 4 via the lifting and transfer mechanism 8 and then output through the upper tray conveying mechanism 4. The lifting and transfer mechanism 8 then descends to align with the lower tray conveying mechanism 5. The lower tray conveying mechanism 5 conveys the empty tray to the lifting and transfer mechanism 8. The lifting and transfer mechanism then rises to align with the upper tray conveying mechanism 4 and conveys the empty tray to the second tray loading station where the second tray fixing mechanism 7 is located for loading.

[0072] Example 6:

[0073] The sixth embodiment of the material dual-station palletizing method of the present invention uses the material dual-station palletizing system of embodiment three, and includes the following steps:

[0074] Further, the tray feeding process is as follows: First, the first lifting and fixing tray mechanism 6 and the lifting and transferring mechanism 8 are both aligned with the lower tray conveying mechanism 5. Second, the empty tray is successively conveyed to the first lifting and fixing tray mechanism 6 and the lifting and transferring mechanism 8 through the lower tray conveying mechanism 5. Then, the first lifting and fixing tray mechanism 6 rises to align with the upper tray conveying mechanism 4 and reaches the first tray loading station. The lifting and transferring mechanism 8 rises to align with the upper tray conveying mechanism 4 and conveys the empty tray to the second fixing tray mechanism 7, so that the empty tray reaches the second tray loading station where the second fixing tray mechanism 7 is located.

[0075] The material loading process: The material loading device 3 loads the material into the trays 9 on the first lifting and fixing mechanism 6 and the second fixing mechanism 7 in sequence;

[0076] Discharge process: First, the first lifting and fixing mechanism 6 and the lifting and transferring mechanism 8 descend to align with the lower conveying mechanism 5. The tray 9 containing material on the first lifting and fixing mechanism 6 is conveyed to the lifting and transferring mechanism 8. The lifting and transferring mechanism 8 then rises to align with the upper conveying mechanism 4, and the tray 9 containing material on the lifting and transferring mechanism 8 is output through the upper conveying mechanism 4. Second, the lifting and transferring mechanism 8 descends to align with the lower conveying mechanism 5, allowing the empty trays on the lower conveying mechanism 5 to be transferred to the first lifting and fixing mechanism 6. The first lifting and fixing mechanism 6 then rises to align with the upper conveying mechanism 5. Alignment 4: Empty trays are transported to the first tray loading station for loading. Then, the lifting and transfer mechanism 8 rises to align with the upper tray conveying mechanism 4. The tray 9 containing material on the second fixed tray mechanism 7 is transferred to the upper tray conveying mechanism 4 via the lifting and transfer mechanism 8, and then output through the upper tray conveying mechanism 4. The lifting and transfer mechanism 8 then descends to align with the lower tray conveying mechanism 5. The lower tray conveying mechanism 5 transports empty trays to the lifting and transfer mechanism 8. The lifting and transfer mechanism 8 then rises to align with the upper tray conveying mechanism 4, and the empty trays are transported to the second tray loading station where the second fixed tray mechanism 7 is located for loading.
