[0045] Another core of the present invention is to disclose a material unloading device including the above-mentioned tray unloading mechanism.

[0046] Another core of the present utility model is to disclose a material detection device including the above-mentioned material discharge device.

[0047] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0048] Combine Figure 1 and Figure 2 The tray unloading mechanism disclosed in the present invention includes a carrying assembly 100, a lifting assembly 200 and an auxiliary carrying assembly 300. The carrying assembly 100 is used to carry the tray 800. The lifting assembly 200 is used to drive the carrying assembly 100 to descend from the initial position to multiple preset carrying positions in sequence, until it finally descends to the unloading station for transferring the tray 800 to the downstream equipment, so as to stack a tray 800 in sequence at different preset carrying positions, and finally transfer the loaded tray 800 from the unloading station to the downstream equipment, and drive the carrying assembly 100 to rise from the unloading station to the initial position to start carrying the tray 800 again; the auxiliary carrying assembly 300 is used to drive the carrying assembly 100 to descend from the initial position to multiple preset carrying positions in sequence, until it finally descends to the unloading station for transferring the tray 800 to the downstream equipment, so as to stack a tray 800 in sequence at different preset carrying positions, and finally transfer the loaded tray 800 from the unloading station to the downstream equipment, and The auxiliary driving member 310 can be moved between the avoidance position and the carrying position. The avoidance position refers to the position of avoiding the carrying component 100 and the tray 800 located on the carrying component 100, and the carrying position refers to the position of carrying the tray 800; wherein, when the carrying component 100 descends from a preset carrying position closest to the unloading station to the unloading station, the auxiliary carrying component 300 moves from the avoidance position to the carrying position to carry the tray 800, ensuring uninterrupted unloading of the tray 800; when the carrying component 100 rises to the initial position from the unloading station, the auxiliary carrying component 300 moves from the carrying position to the avoidance position without affecting the unloading of the carrying component 100 again.

[0049] It is defined that the carrying component 100 is provided with a first carrying surface for carrying the pallet 800; the auxiliary carrying component 300 is provided with a second carrying surface for carrying the pallet 800, and the lifting component 200 is used to drive the carrying component 100 to rise and fall, so that the carrying component 100 can move between the initial position carrying one pallet 800, the various preset carrying positions carrying multiple pallets 800, and the unloading station for transferring the pallet 800 to the downstream equipment, that is, along the descending direction of the carrying component 100, the initial position, the various preset carrying positions and the unloading station are arranged in sequence.

[0050] Among them, when the carrying component 100 is in the unloading station, the auxiliary carrying component 300 is in the carrying position, and the second carrying surface is located above the first carrying surface, and is in a carrying state that can carry the pallet 800; when the carrying component 100 is in the initial position, and the auxiliary carrying component 300 is in the carrying position, the second carrying surface is located below the first carrying surface and is in an unloaded state or the second carrying surface is flush with the first carrying surface, and together they carry the pallet 800; when the carrying component 100 is in the preset carrying position, the auxiliary carrying component 300 is in an avoidance position to avoid the carrying component 100 and the pallet 800 located on the carrying component 100, and does not affect the lifting and lowering of the carrying component 100 and the pallet 800.

[0051] In the specific process of unloading the pallet 800, in the initial situation, the auxiliary carrying component 300 is in the avoidance position, and the carrying component 100 is in the initial position. When the first pallet 800 is transferred to the pallet unloading mechanism by the robot or other pallet transfer mechanism 900, it is carried by the carrying component 100 at the initial position. After the carrying is completed, the carrying component 100 moves down to the first preset carrying position. At this time, the second pallet 800 is transferred to the pallet unloading mechanism by the pallet transfer mechanism 900. The second pallet 800 is also carried by the carrying component 100 and stacked. Above the first pallet 800, the carrying component 100 then repeats the above process, gradually descending and continuously supporting more pallets 800. After the carrying component 100 supports a preset number of pallets 800, the carrying component 100 moves down to the unloading station and transports the pallets 800 to the downstream equipment. At this time, the auxiliary carrying component 300 moves from the avoidance position to the carrying position to support the next pallet 800 transferred by the pallet transfer mechanism 900 through the second carrying surface, thereby ensuring the consistency and continuity of the production rhythm of the pallet transfer mechanism 900 and other mechanisms. After the carrier assembly 100 transfers all the pallets 800 it carries to the downstream equipment at the unloading station, the carrier assembly 100 moves to the initial position again. During the process of the carrier assembly 100 rising to the initial position, it can lift a pallet 800 located on the auxiliary carrier assembly 300 and carry it on its first carrying surface, so that the auxiliary carrier assembly 300 is in an unloaded state, or the first carrying surface of the carrier assembly 100 is flush with the second carrying surface of the auxiliary carrier assembly 300, and the two jointly carry the pallet 800. At this time, the auxiliary carrier assembly 300 is moved to the avoidance position by the auxiliary driving member 310, without affecting the downward movement of the carrier assembly 100 and the pallet 800 on the carrier assembly 100. The above process is repeated to achieve uninterrupted unloading of pallets 800.

[0052] Compared with the prior art, the tray unloading mechanism disclosed in the present invention realizes uninterrupted unloading of the tray 800 by setting the auxiliary bearing assembly 300 , has a simple structure, and ensures production efficiency.

[0053] It is understood that the distance between two adjacent preset loading positions along the descending direction of the load-carrying assembly 100 is equal to the thickness of the pallet 800. The load-carrying assembly 100 descends sequentially based on the number of pallets 800 that the load-carrying assembly 100 can actually carry or the preset number, ensuring that the pallet transfer mechanism 900 can sequentially stack multiple pallets 800 on the load-carrying assembly 100 at the same position. In other words, a complete lifting process of the load-carrying assembly 100 can unload a group (a stack of pallets 800).

[0054] When the pallet 800 is transferred to the load-bearing assembly 100 by the pallet transfer mechanism 900, the pallet 800 and the first load-bearing surface of the load-bearing assembly 100 in the initial position (or the upper surface of the pallet 800 located on the top layer of the load-bearing assembly 100 in the preset load-bearing position) can be in contact with or have a certain gap. For example, after the pallet 800 is transferred to the top of the first load-bearing surface by the pallet transfer mechanism 900, the pallet transfer mechanism 900 releases the pallet 800, and the pallet 800 can fall freely onto the first load-bearing surface or the pallet 800.

[0055] In addition, a sensor can be provided through the bracket 400 , and the sensor is used to detect whether the tray 800 has been fed. When the feeding of the tray 800 is detected, the carrying assembly 100 is driven downward by the lifting assembly 200 .

[0056] The aforementioned supporting assembly 100, lifting assembly 200 and auxiliary supporting assembly 300 can all be placed on the ground or on a rack via a bracket 400. The lifting assembly 200 can specifically be a transmission screw mechanism, a cylinder slider mechanism, or the like.

[0057] In order to ensure the accuracy of the placement of the pallet 800 on the carrier assembly 100 and the accuracy of the placement of the material on the pallet 800, the pallet unloading mechanism disclosed in the present invention also includes a centering positioning assembly 500, which is used to position the pallet 800 located on the uppermost layer of the carrier assembly 100 in two directions perpendicular to each other. That is, after each pallet 800 is transferred to the first carrying surface by the pallet transfer mechanism 900, the centering positioning assembly 500 positions the pallet 800 to ensure the accuracy of the placement of each pallet 800 on the carrier assembly 100. Alternatively, the centering positioning assembly 500 can also position the pallet 800 carried by the auxiliary carrier assembly 300 to prevent the pallet 800 from following the auxiliary carrier assembly 300 when the auxiliary carrier assembly 300 moves from the carrying position to the avoidance position.

[0058] Specifically, the centering positioning assembly 500 includes a reference positioning plate 550, a first positioning baffle 510 and a first positioning motor 520. The first positioning baffle 510 is arranged at the output end of the first positioning motor 520, and the first positioning motor 520 is used to push the first positioning baffle 510 in the direction of the reference positioning plate 550. The tray 800 on the first supporting surface is located between the reference positioning plate 550 and the first positioning baffle 510. The reference positioning plate 550 and the first positioning baffle 510 can press and position the tray 800 on both sides along the first direction.

[0059] In addition, the centering positioning assembly 500 also includes two second positioning baffles 530 and two second positioning motors 540. The second positioning baffles 530 are arranged one by one at the output ends of the second positioning motors 540, and the second positioning motors 540 are used to push the corresponding second positioning baffles 530 to move closer to or away from each other. The tray 800 is located between the two second positioning baffles 530. The two second positioning baffles 530 are used to press and position the two sides of the tray 800 along the second direction, and the second direction is perpendicular to the first direction.

[0060] Combine Figure 1 The moving directions of the first positioning baffle 510 and the second positioning baffle 530 are perpendicular to each other, so as to position the tray 800 in the length direction and the width direction respectively.

[0061] In order to facilitate the positioning of the centering positioning component 500, bosses are provided on the edges around the tray 800. The bosses can also be used to prevent materials on the tray 800 from falling and to provide a suction cup for transferring the tray 800.

[0062] In a specific embodiment, combining Figure 1 The lifting assembly 200 and the auxiliary load-bearing assembly 300 are respectively mounted on either side of the tray 800 on the load-bearing assembly 100 via a bracket 400. The reference positioning plate 550 and the lifting assembly 200 are mounted on the same side of the tray 800 and on the same bracket 400. The first positioning motor 520 and the auxiliary load-bearing assembly 300 are also mounted on the same side of the tray 800 and on the same bracket 400. By adjusting the mounting position of the auxiliary drive member 310 on the bracket 400, the auxiliary load-bearing member 700 can be adapted to assist in supporting trays 800 of different sizes.

[0063] Combine Figure 2 The load-bearing assembly 100 includes at least two first support members, each of which forms a first load-bearing surface. The auxiliary load-bearing assembly 300 includes at least two second support members, each of which forms a second load-bearing surface. When the auxiliary load-bearing assembly 300 is in the load-bearing position, the first support members and the second support members are staggered along the lifting direction of the load-bearing assembly 100, so that when the load-bearing assembly 100 rises and moves from the unloading station to the initial position, it can be staggered with the auxiliary load-bearing member 700 and correspondingly support the pallet 800 located on the second support member.

[0064] In addition to being arranged on the same bracket 400 as the first positioning motor 520, the auxiliary supporting assembly 300 can also be arranged on the same bracket 400 as the second positioning motor 540. Correspondingly, the auxiliary supporting assembly 300 can also be arranged in two groups and supported at both ends of the tray 800 respectively.

[0065] It is understandable that the reference positioning plate 550 can be fixedly set on the bracket 400, or movably set on the bracket 400 through the position of the cylinder, the latter being convenient for adjusting the positioning reference for pallets 800 of different sizes.

[0066] The auxiliary driving member 310 includes but is not limited to a cylinder, a motor, etc. The position movement of the auxiliary bearing assembly 300 between the bearing position and the avoidance position includes but is not limited to translation, rotation and a combination of the two, which will not be repeated here.

[0067] In a specific embodiment disclosed in the present utility model, the pallet unloading mechanism also includes a transmission component 600, which is provided with a conveying surface for conveying the pallet 800. When the carrying component 100 is in the unloading station, the first carrying surface is below the conveying surface, and the transmission component 600 is used to convey the pallet 800 to the downstream equipment.

[0068] During the process of the carrier assembly 100 loaded with pallets 800 descending from the preset carrying position to the unloading station, the auxiliary carrier 700 is arranged so that the carrier assembly 100 is in a fully loaded state and no longer receives pallets 800. At the same time, the first carrying surface moves down below the conveying surface. The pallets 800 on the carrier assembly 100 are blocked by the conveying surface and stay on the conveying surface, thus achieving the transfer of pallets 800 between the carrier assembly 100 and the conveying assembly 600. After the conveying assembly 600 transfers the pallets 800, the carrier assembly 100 remains unloaded and rises again to the initial position to unload a new round of pallets 800.

[0069] The transmission component 600 is usually a conveyor belt. After the pallet 800 is transported to the conveying surface of the conveyor belt, the conveyor belt is started to transport the pallet 800, and the pallet 800 can be immediately transported to the downstream equipment.

[0070] Combine Figure 5 The transmission component 600 has two workstations that can place two groups of pallets 800 at the same time. One of the workstations is used as a unloading workstation for handing over the pallets 800 to the carrying component 100, and the other workstation is used as a docking workstation for docking with downstream equipment. The transmission component 600 drives the pallets 800 to move from the unloading workstation to the docking workstation.

[0071] In other embodiments, when the carrier assembly 100 descends to the unloading station, the transmission assembly 600 and the pallet 800 are directly transferred away by a transfer device such as a robot, and the carrier assembly 100 remains unloaded and rises again to the initial position to unload a new round of pallets 800. This will not be described in detail here. The transmission assembly 600 may be a base, etc.

[0072] Combine Figure 3-Figure 5 , Figure 5The direction of the middle arrow indicates the flow direction of the pallet 800. The material unloading device disclosed in the present invention includes an empty pallet loading mechanism, a pallet transfer mechanism 900 and the above-mentioned pallet unloading mechanism. The pallet transfer mechanism 900 is used to transfer the empty pallet loaded by the empty pallet loading mechanism to the pallet unloading mechanism.

[0073] The empty pallet loading mechanism sequentially loads empty pallets. Once the empty pallets are loaded with material, the pallet transfer mechanism 900 transfers the loaded pallet 800 to the pallet unloading mechanism, enabling simultaneous unloading of the pallet 800 and the material. Alternatively, the empty pallet loading mechanism sequentially loads empty pallets. After the pallet transfer mechanism 900 transfers the empty pallet to the pallet unloading mechanism, the centering assembly 500 precisely positions the empty pallet. Once positioned, the empty pallet is loaded with material, and finally, the pallet unloading mechanism unloads the pallet 800 and the material together. Specifically, the empty pallet can be loaded with material at either the empty pallet loading mechanism or the pallet unloading mechanism.

[0074] Since the above-mentioned tray unloading mechanism is provided, the above-mentioned structure and beneficial effects are also obtained. Other structures refer to the prior art and will not be described in detail here.

[0075] Specifically, the above-mentioned empty pallet loading mechanism can be a variety of structures such as a conveyor belt. In a specific embodiment disclosed in the present utility model, combined with Figure 3 and Figure 5 The empty pallet loading mechanism adopts a structure similar to that of the pallet transfer mechanism 900, including a carrier 700, a transmission component 730 and a lifting component 710. The carrier 700 is provided with a third carrying surface for carrying a plurality of stacked empty pallets. The pallet transfer mechanism 900 is used to transfer the pallet 800 located on the top layer of the third carrying surface to the carrier assembly 100 of the pallet unloading mechanism. The transmission component 730 is used to transfer the pallet 800 to the lifting station; the lifting component 710 is used to drive the carrier 700 to lift the pallet 800 at the lifting station in turn, so that each empty pallet can be loaded in turn to the loading position for transportation by the pallet transfer mechanism 900.

[0076] The aforementioned supporting member 700 and the supporting assembly 100 may adopt the same structure, the lifting member 710 and the lifting assembly 200 may adopt the same structure, and the transmission component 730 and the transmission assembly 600 may adopt the same structure.

[0077] Combine Figure 5 Usually, the transmission component 730 has two stations that can place two groups of pallets 800 at the same time, one of which is used as a preparation station and the other as a lifting station. The transmission component 730 drives the pallets 800 from the preparation station to the lifting station to ensure a continuous supply of pallets 800.

[0078] Furthermore, an auxiliary baffle or other stopper is provided downstream of the conveying member 730 in the conveying direction. The auxiliary baffle is used to stop the pallet 800 at the lifting station. Opposite photoelectric sensors can be provided on the conveying member 730 as detection elements to detect whether the pallet 800 has moved to the lifting station. When the pallet 800 is detected at the lifting station, the conveying member 730 stops conveying.

[0079] In order to ensure the accuracy of material placement and reliable loading and unloading of the pallet 800, the empty pallet loading mechanism also includes a positioning component that can position the pallet 800. The positioning component can be arranged in the same manner as the above-mentioned centering positioning component 500, which will not be repeated here.

[0080] The pallet transfer mechanism 900 transfers one pallet 800 at a time. In order to avoid the pallet 800 at the empty pallet loading mechanism from sticking when the pallet transfer mechanism 900 is transferring the pallet, in some embodiments, the empty pallet loading mechanism further includes two sets of auxiliary pallet separation assemblies, which are combined with the pallet Figure 3 The auxiliary tray separation assembly includes a tray separation drive 721 and a tray separation plate 720. The tray separation plate 720 is arranged at the output end of the tray separation drive 721. The two sets of auxiliary tray separation assemblies are used to press the tray 800 located below the top tray 800 on the empty tray loading mechanism.

[0081] Specifically, after the auxiliary tray separation assembly presses the second pallet 800 from top to bottom on the empty pallet loading mechanism, the pallet transfer mechanism 900 grabs the pallet 800 located at the top layer of the empty pallet loading mechanism. After the pallet 800 located at the top layer is transferred away by the pallet transfer mechanism 900, the auxiliary tray separation assembly releases the pressure on the second pallet 800, and the lifting member 710 drives the supporting member 700 to move upward, so that the pallet 800 located at the top layer of the supporting member 700 at this time moves to a position where it can be grabbed by the pallet transfer mechanism 900.

[0082] The material detection equipment disclosed in the present invention includes the above-mentioned material unloading device, so it also has the above-mentioned structure and beneficial effects, which will not be described in detail here.

[0083] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Specific technical means in some embodiments may be incorporated in part or in whole into another embodiment, unless expressly excluded by another embodiment. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
