Description

Technical Field

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

[0002] An existing magnetic levitation bottle delivery system (application number CN202010560619.3) includes a servo-driven wheel assembly, a magnetic levitation conveyor track, a first tray loading station, a second tray loading station, and multiple magnetically levitated actuators for single-row bottle transport along the magnetic levitation conveyor track. The magnetic levitation conveyor track is circular. The servo-driven wheel assembly is located on one side of the magnetic levitation conveyor track and is used to transfer bottles from the drawing and sealing machine to the magnetically levitated actuators. The first and second tray loading stations are located to the side of the magnetic levitation conveyor track and are used to load the single-row bottles from the magnetically levitated actuators into trays or bottle protection frames. The specific tray loading process is as follows: after a tray is full of bottles on the collecting platform, the tray pushing mechanism pushes the full tray of bottles onto the tray or bottle protection frame at the tray loading station, completing the tray loading. The existing magnetic levitation bottle delivery system has the following shortcomings:

[0003] 1) Bottles may be missing during the conveying process. If there are missing bottles in the bottle row, the palletizing requirements cannot be met. The existing magnetic levitation logistics bottle conveying system cannot achieve palletizing without missing bottles; it also cannot make the missing bottle row flow back to the conveying mechanism in time for re-palletizing, resulting in low efficiency.

[0004] 2) The bottle is pushed horizontally into the tray at the traying station by the tray-pushing mechanism. When the tray-pushing mechanism moves backward and separates from the bottle, the bottle tends to move backward a small distance with the tray-pushing mechanism, resulting in improper placement of the bottle, poor traying effect, gaps between the bottles, and collisions and breakage of the bottles during subsequent movement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a material loading system and method that can achieve unsufficient material loading, timely return of unqualified materials for reloading, and improve production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A material palletizing system includes a material conveying device, which comprises a material input mechanism and a material conveying mechanism arranged sequentially. An inclined palletizing device is provided on one side of the material conveying mechanism. The material conveying mechanism is equipped with multiple sets of material conveying components and a detection mechanism. Each material conveying component has multiple material placement sections. The detection mechanism is used to detect whether any material is missing from the material placement sections. 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 to return material from the missing material conveying component to the material input mechanism.

[0008] As a further improvement to the above technical solution:

[0009] The output end of the material input mechanism is provided with a material buffer mechanism, and the material return mechanism is located between the material buffer mechanism and the material conveying mechanism.

[0010] The material conveying device also includes a variable pitch conveying mechanism and a feeding puller. The material input mechanism, variable pitch conveying mechanism, feeding puller and material conveying mechanism are arranged in sequence, and the variable pitch conveying mechanism is located on one side of the material buffer mechanism.

[0011] The tilting tray loading device includes a tilting mechanism for tilting the tray and a tilting tray loading mechanism disposed between the material conveying mechanism and the tilting mechanism. The tilting tray loading mechanism is connected to at least one set of material conveying components for tilting the material on the material conveying components into the tray on the tilting mechanism.

[0012] The tilting mechanism includes a tray lifting assembly, a tray placement assembly rotatably mounted on the tray lifting assembly, and a tilting drive assembly for driving the tray placement assembly to rotate. The tray lifting assembly is provided with a horizontal limiting component and a tilt limiting component for limiting the horizontal position and tilt position of the tray placement assembly, respectively.

[0013] The tray body is provided with a gate for material to enter and exit on one side, and the tray feeding assembly is provided with a switching mechanism for opening and closing the gate.

[0014] The tilting loading mechanism includes a material tilting component for tilting materials and a tilting transfer mechanism for tilting and transferring the tilted materials on the material tilting component to the tray body on the tilting mechanism. The material tilting component is connected to at least one set of material conveying components, and the material conveying mechanism is provided with a material pushing mechanism for pushing the materials on the connected material conveying components to the material tilting component.

[0015] The material tilting assembly includes a rotatably mounted material placement seat, a material tilting drive for driving the material placement seat to rotate, a movable seat that reciprocates between the material conveying mechanism and the tilting mechanism, and a reciprocating drive for driving the movable seat to reciprocate. The material placement seat is rotatably mounted on the movable seat.

[0016] The movable seat is provided with a discharge trough on the side facing the material conveying mechanism, and each discharge trough is provided with a suction mechanism for adsorbing materials.

[0017] A material palletizing method, using the aforementioned material palletizing system, includes the following steps:

[0018] S1, Feeding: The material conveying mechanism causes the material conveying assembly to move forward, and the material is conveyed by the material input mechanism to the material placement part of the material conveying assembly;

[0019] S2. Loading or Returning: The detection mechanism checks whether there is any missing material in the material placement section of the material conveying component. If there is no missing material, the material on the material conveying component is conveyed to the tilting loading device, and then tilted and loaded onto the tray by the tilting loading device. If there is any missing material, the material on the material conveying component is returned to the material input mechanism by the material return mechanism.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] The material palletizing system of this invention can both palletize materials on material conveying components with no missing materials and return materials on material conveying components with missing materials to the material input mechanism. The returned materials can then be conveyed again by the material input mechanism to the material placement section of the material conveying component on the material conveying mechanism, enabling subsequent material to be palletized again, thus improving production efficiency. In other words, this material palletizing system can achieve palletizing without missing materials and can also promptly return defective materials for re-palletizing, thereby improving production efficiency.

[0022] The material palletizing method of the present invention can both achieve palletizing of materials on material conveying components with no missing materials and return materials on material conveying components with missing materials to the material input mechanism. The returned materials can then be conveyed again by the material input mechanism to the material placement section of the material conveying component on the material conveying mechanism, enabling subsequent material to be palletized again, thus improving production efficiency. In other words, this material palletizing method can achieve palletizing without missing materials and can also promptly return defective materials for re-palletizing, thereby improving production efficiency.

[0032] Example 1:

[0033] Figures 1 to 5An embodiment of the material palletizing system of the present invention is shown. The material palletizing system of this embodiment includes a material conveying device 1, which includes a material input mechanism 11 and a material conveying mechanism 14 arranged sequentially. An inclined palletizing device is provided on one side of the material conveying mechanism 14. The material conveying mechanism 14 is provided with multiple sets of material conveying components 141 and a detection mechanism. The material conveying components 141 are provided with multiple material placement parts 142. The detection mechanism is used to detect whether there is missing material in the material placement parts 142. The inclined palletizing device is connected to at least one set of material conveying components 141. A material return mechanism 16 is provided between the material input mechanism 11 and the material conveying mechanism 14 for returning the material on the missing material conveying component 141 to the material input mechanism 11.

[0034] The production process of this material loading system is as follows: The material conveying mechanism 14 causes the material conveying component 141 to move forward. The material is conveyed by the material input mechanism 11 to the material placement part 142 of the material conveying component 141 on the material conveying mechanism 14. The detection mechanism detects whether there is missing material in the detection material placement part 142 of the material conveying component 141. If there is no missing material, the material on the material conveying component 141 is conveyed by the material conveying component 141 to the tilting loading device, and then tilted and loaded onto the tray by the tilting loading device. If there is missing material, the material on the material conveying component 141 is returned to the material input mechanism 11 by the material return mechanism 16.

[0035] This material palletizing system can both palletize materials on the material conveying assembly 141 with no missing materials and return materials on the material conveying assembly 141 with missing materials to the material input mechanism 11. The returned materials can then be conveyed again by the material input mechanism 11 to the material placement section 142 of the material conveying assembly 141 on the material conveying mechanism 14, enabling subsequent material to be palletized again, thus improving production efficiency. In other words, this material palletizing system can both achieve palletizing with no missing materials and promptly return unqualified materials for re-palletizing, thereby improving production efficiency.

[0036] In this embodiment, the output end of the material input mechanism 11 is provided with a material buffer mechanism 15, and the material return mechanism 16 is located between the material buffer mechanism 15 and the material conveying mechanism 14. The material conveyed by the material input mechanism 11 can be buffered by the material buffer mechanism 15, and at the same time, the material returned by the material return mechanism 16 can also be buffered by the material buffer mechanism 15.

[0037] In this embodiment, the material conveying device 1 further includes a variable-pitch conveying mechanism 12 and a feeding puller 13. The material input mechanism 11, the variable-pitch conveying mechanism 12, the feeding puller 13, and the material conveying mechanism 14 are arranged sequentially, with the variable-pitch conveying mechanism 12 located on one side of the material buffer mechanism 15. The material input mechanism 11 conveys the material to the material buffer mechanism 15 or the variable-pitch conveying mechanism 12. The variable-pitch conveying mechanism 12 changes the pitch of the material and then conveys it into the feeding puller 13, which then conveys the material to the material conveying mechanism 14. The purpose of the variable-pitch conveying mechanism 12 in changing the pitch of the material is to make the pitch of the material the same as the pitch of the material placement section 142.

[0038] In this embodiment, the tilting tray loading device includes a tilting mechanism 2 for tilting the tray 4 and a tilting tray loading mechanism 3 disposed between the material conveying mechanism 14 and the tilting mechanism 2. The tilting tray loading mechanism 3 is connected to at least one set of material conveying components 141 and is used to tilt the material on the material conveying components 141 into the tray 4 on the tilting mechanism 2.

[0039] Panning process: After the tilting mechanism 2 tilts the pan 4, the tilting panning mechanism 3 tilts the material from the material conveying assembly 141 on the material conveying device 1 into the pan 4 on the tilting mechanism 2. This process is repeated so that the material is arranged in rows along the tilting direction of the pan 4 until the pan is full. Because the material is tilted into the equally tilted pan 4 (the tilting direction and angle of the material and the pan 4 are the same), when the tilting panning mechanism 3 moves backward and separates from the material, the material will not move backward with the tilting panning mechanism 3 under the action of gravity, thus improving the panning effect.

[0040] In this embodiment, as Figure 3 and Figure 4 As shown, the tilting mechanism 2 includes a tray lifting assembly 23, a tray placement assembly 21 rotatably mounted on the tray lifting assembly 23, and a tilting drive assembly 22 for driving the tray placement assembly 21 to rotate. The tray lifting assembly 23 is provided with a horizontal limiting component 24 and a tilting limiting component 25 for respectively limiting the horizontal and tilting positions of the tray placement assembly 21. The height of the tray placement assembly 21 can be adjusted by the lifting action of the tray lifting assembly 23, thus adjusting the height of the tray 4 when loading the tray. The tilting drive assembly 22 drives the tray placement assembly 21 to rotate, causing the tray 4 of the tray placement assembly 21 to tilt to an appropriate angle. The horizontal limiting component 24 limits the tray placement assembly 21 to a horizontal position, and the tilting limiting component 25 limits the tray placement assembly 21 to a predetermined tilting position.

[0041] In this embodiment, a gate 41 for material entry and exit is provided on one side of the tray 4, and a switching mechanism 5 for opening and closing the gate 41 is provided on the tray assembly 21. Specifically, the gate 41 is located on the top side of the tray 4 when it is in a predetermined tilt position, so that the material can enter from the top side of the tray 4. Under the action of gravity, the material inside the tray 4 is arranged in rows close together.

[0042] In this embodiment, the tilting tray mechanism 3 includes a material tilting component 31 for tilting materials and a tilting transfer mechanism 32 for tilting and transferring the tilted material on the material tilting component 31 to the tray body 4 on the tilting tray mechanism 2. The material tilting component 31 is connected to at least one set of material conveying components 141. The material conveying mechanism 141 is provided with a material pushing mechanism 6 for pushing the material on the connected material conveying component 141 to the material tilting component 31. After the material conveying component 141 is connected to the material tilting component 31, the material pushing mechanism 6 pushes the material on the material conveying component 141 to the material tilting component 31, and then the material tilting component 31 tilts the material to a predetermined angle. Then, the tilting transfer mechanism 32 tilts and transfers the tilted material on the material tilting component 31 to the tilting tray mechanism 2, specifically tilting and transferring the tilted material on the material tilting component 31 to the tray body 4 on the tilted tray loading component 21.

[0043] In this embodiment, as Figure 5 As shown, the material tilting assembly 31 includes a rotatably mounted material placement seat 311, a material tilting drive 312 for driving the material placement seat 311 to rotate, a movable seat 313 that reciprocates between the material conveying mechanism 14 and the tilting mechanism 2, and a reciprocating drive 314 for driving the movable seat 313 to reciprocate. The material placement seat 311 is rotatably mounted on the movable seat 313. The material tilting drive 312 drives the material placement seat 311 to rotate, tilting the material on the material placement seat 311. The reciprocating drive 314 drives the movable seat 313 to reciprocate between the material conveying mechanism 14 and the tilting mechanism 2, thereby adjusting the position of the material placement seat 311, facilitating the tilting transfer mechanism 32 to obtain material from the material placement seat 311, and providing operating space for the tilting transfer mechanism 32 to obtain material.

[0044] In this embodiment, a discharge trough 7 is provided on the side of the movable seat 313 facing the material conveying mechanism 14, and each discharge trough 7 is provided with a suction mechanism 8 for adsorbing materials. Each discharge trough 7 is used to place a row of materials, and the materials in the discharge trough 7 are adsorbed and fixed by the suction mechanism 8 to prevent them from falling out.

[0045] The materials mentioned above are bottle-type containers. The material conveying mechanism 14 is a magnetic levitation conveying mechanism.

[0046] Example 2:

[0047] The material loading method of this embodiment, using the material loading system of this embodiment, includes the following steps:

[0048] S1, Feeding: The material conveying mechanism 14 causes the material conveying assembly 141 to move forward, and the material is conveyed by the material input mechanism 11 to the material placement part 142 of the material conveying assembly 141;

[0049] S2. Loading or Returning: The detection mechanism detects whether there is missing material in the detection material placement section 142 of the material conveying component 141 on the material conveying mechanism 14. If there is no missing material, the material on the material conveying component 141 is conveyed to the tilting loading device and then tilted onto the tray by the tilting loading device. If there is missing material, the material on the material conveying component 141 is returned to the material input mechanism 11 by the material return mechanism 16.

[0050] This material palletizing method can both palletize materials on the material conveying assembly 141 with no missing materials and return materials on the material conveying assembly 141 with missing materials to the material input mechanism 11. The returned materials can then be conveyed again by the material input mechanism 11 to the material placement section 142 of the material conveying assembly 141 on the material conveying mechanism 14, enabling subsequent material to be palletized again, thus improving production efficiency. In other words, this material palletizing method can achieve palletizing without missing materials and can also promptly return unqualified materials for re-palletizing, thereby improving production efficiency.

[0051] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention.
