[0040] The core of the utility model is to disclose a material unloading device to achieve continuous supply of pallets.

[0041] Another core of the present utility model is to disclose a material detection device including the above-mentioned material unloading device.

[0042] 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.

[0043] Combine Figure 1-Figure 7The material unloading device disclosed in the embodiment of the present invention includes a first pallet conveying assembly 100, a second pallet conveying assembly 200 and a transmission mechanism 300, wherein the first pallet conveying assembly 100 is used to convey the pallet 400 to the transmission station, the transmission mechanism 300 is used to convey the pallet 400 from the transmission station to the loading station, and the second transmission mechanism 300 is used to convey the pallet 400 from the loading station to the downstream equipment. The pallet 400 is loaded with materials at the loading station or the transmission station, thereby completing the material unloading process.

[0044] Specifically, the first pallet conveying assembly 100 includes a first carrier 110, a first lifting member 120 and a first transmission member 130. The first carrier 110 is used to carry empty pallets 400. The first transmission member 130 is used to transmit the stacked empty pallets 400 to the loading station. The first lifting member 120 is used to drive the first carrier 110 to lift the stacked empty pallets 400 from the loading station to the transmission station in sequence, and be transported away by the transmission mechanism 300. After a group of empty pallets 400 are transmitted, the first lifting member 120 drives the first carrier 110 to descend to the loading station. After the first transmission member 130 transmits a group of empty pallets 400 to the loading station again, the first carrier 110 lifts the pallets 400 from the loading station to the transmission station in sequence again.

[0045] The second pallet conveying assembly 200 includes a second carrier 210, a second lifting member 220 and a second transmission member 230. The second carrier 210 is used to carry the pallet 400. The second lifting member 220 is used to drive the second carrier 210 to descend in sequence so that the pallets 400 at the loading station can be stacked one by one on the second carrier 210, and the pallets 400 are transferred to the unloading station located on the second transmission member 230. After the conveying mechanism 300 moves the pallet 400 from the conveying station to the loading station, the pallet 400 is carried by the second carrier 210. As the second carrier 210 descends in sequence, each pallet 400 is stacked on the second carrier 210 in sequence. After the stacked number of pallets 400 reaches a preset number, the first carrier 110 drives the pallet 400 to descend to the unloading station and completes the handover of the pallet 400 with the second conveying member 230. After the second conveying member 230 moves the pallet 400 away from the unloading station, the second carrier 210 is reset and continues to receive subsequent pallets 400.

[0046] Here, a group of trays 400 refers to a plurality of trays 400 stacked in sequence in a vertical direction.

[0047] Compared with the existing technology, the present invention can realize automatic loading of empty pallets 400 and automatic unloading of fully loaded pallets 400, ensuring the continuous supply of pallets 400, promoting the degree of automation of the material unloading process, improving production efficiency and reducing production costs.

[0048] Specifically, combined Figure 6 In order to ensure the stable flow of the pallet 400 between the loading station, the transfer station and the loading station, the first pallet conveying assembly 100 includes a pre-positioning assembly 150. The pre-positioning assembly 150 includes two initial positioning plates movably arranged on the first transmission member 130 along the adjustment direction. The adjustment direction is perpendicular to the conveying direction of the first transmission member 130, and along the conveying direction of the first transmission member 130, the two initial positioning plates are respectively arranged on both sides of the first transmission member 130 for positioning the pallet 400 on the first transmission member 130.

[0049] Combine Figure 6 After a group of pallets 400 are manually or mechanically placed on the first conveyor 130, the two initial positioning plates are adjusted so that they are pressed against both sides of the pallets 400, ensuring that the pallets 400 are in the preset posture when they move to the loading station. Alternatively, the spacing between the two initial positioning plates can be pre-adjusted. When a group of pallets 400 are placed on the first conveyor 130, as the first conveyor 130 is transported, the pallets 400 can be adjusted to the preset posture as they pass through the transmission channel formed by the two initial positioning plates. The two initial positioning plates can be driven and moved by a cylinder or manually adjusted.

[0050] Combine Figure 2 and Figure 3 In order to avoid the situation where the pallet 400 at the transfer station is stuck to the pallet 400 located below the pallet 400 when the transmission mechanism 300 transmits the pallet 400, in some embodiments, the first pallet conveying assembly 100 also includes at least one group of auxiliary separation assemblies 140, each group of auxiliary separation assemblies 140 includes a separation drive 141 and a separation plate 142, and the separation plate 142 is arranged at the output end of the separation drive 141. The auxiliary separation assembly 140 is used to apply force to the adjacent pallet 400 located below the transfer station on the first carrier 110 to avoid adhesion between it and the pallet 400 located at the transfer station and being transferred together by the transmission mechanism 300.

[0051] The auxiliary tray separation assembly 140 usually consists of two groups and is used to press the opposite sides of the pallet 400 respectively. Specifically, after the first carrier 110 lifts the pallet 400 at the top to the transfer station, the tray separation drive 141 drives the tray separation plate 142 to press the pallet 400 under the transfer station. At the same time, the transfer mechanism 300 grabs the pallet 400 at the transfer station. After the pallet 400 at the transfer station is transferred away, the auxiliary tray separation assembly 140 releases the pressure on the pallet 400, and the first carrier 110 continues to lift the pallet 400 to the transfer station.

[0052] Furthermore, an auxiliary baffle is provided downstream of the first conveyor 130 in the conveying direction thereof to limit the position of the tray 400 at the loading station, thereby preventing the tray 400 from deviating from the loading station. Furthermore, an auxiliary baffle or other limiting member is provided downstream of the first conveyor 130 in the conveying direction thereof to limit the position of the tray 400 at the loading station.

[0053] To further optimize the solution, the first pallet conveying assembly 100 also includes a first sensor, which is used to detect whether the first carrier 110 carries a pallet 400, that is, to detect whether all the pallets 400 on the first carrier 110 are transferred. The sensor can be specifically arranged on the first carrier 110 and is a photoelectric detection sensor.

[0054] To ensure the continuity of the production rhythm, the second pallet conveyor assembly 200 further includes an auxiliary carrier 240 and an auxiliary drive. The auxiliary carrier 240 is moved between a stowage position and a carrying position by the auxiliary drive. The stowage position is a position that avoids the second carrier 210 and the pallet 400 located on the second carrier 210, and the carrying position is a position that carries the pallet 400. When the second carrier 210 is lowered from the loading station to the unloading station, the auxiliary carrier 240 moves from the stowage position to the carrying position and is used to carry the pallet 400 located at the loading station. When the second carrier 210 is moved from the unloading station to the loading station, the pallet 400 on the auxiliary carrier 240 is transferred to the second carrier 210, and then the auxiliary carrier 240 moves from the carrying position to the stowage position so as not to affect the descent of the pallet 400.

[0055] It is defined that the second carrier 210 is provided with a first carrying surface for carrying at least one pallet 400, and the second lifting member 220 is used to drive the second carrier 210 to rise and fall, so that the first carrying surface can move between a loading station for carrying one pallet 400, an intermediate position for carrying multiple pallets 400, and an unloading station for transferring pallets 400 to downstream equipment, and along the descending direction of the second carrier 210, the loading station, the intermediate position and the unloading station are arranged in sequence; the auxiliary carrier 240 is provided with a second carrying surface for carrying pallets 400. When the second carrier 210 is in the unloading station, the auxiliary carrier 240 is in the carrying position. At this time, the second carrying surface is located above the first carrying surface and is in a carrying state that can carry the pallet 400; when the second carrier 210 is in the loading station and the auxiliary carrier 240 is in the carrying position, the second carrying surface is located below the first carrying surface and is in an unloaded state, or the first carrying surface is flush with the second carrying surface, and the second carrier 210 and the auxiliary carrier 240 jointly carry the pallet 400; when the second carrier 210 is in the middle position, the auxiliary carrier 240 is in an avoidance position to avoid the second carrier 210 and the pallet 400 located on the second carrier 210.

[0056] Combine Figure 1 , Figure 1The black arrow in the figure indicates the flow direction of the pallets 400. During the specific unloading process of the pallets 400, initially, the auxiliary carrier 240 is in the avoidance position and the second carrier 210 is in the loading station. When the first pallet 400 is transferred to the loading station by the conveyor mechanism 300, it is supported by the second carrier 210 located in the loading station. After the loading is completed, the second carrier 210 moves down to the middle position. After the second pallet 400 is moved to the loading station by the conveyor mechanism 300, it is also supported by the second carrier 210 and stacked on top of the first pallet 400 on the second carrier 210. The second carrier 210 then repeats the above process, gradually descending to continuously support more pallets 400 until the second carrier 210 has supported a predetermined number of pallets 400 and then moves down to the unloading station. The second conveyor 230 is provided with a conveying surface for conveying the pallets 400. When the second lifting member 220 is at the unloading station, the first supporting surface is below the conveying surface. At this point, the auxiliary carrier 240 moves from the avoidance position to the loading position, supporting the next pallet 400 transferred from the conveying mechanism 300 via the second supporting surface, ensuring consistent and continuous production. After the second carrier 210 transfers all of its pallets 400 to the second conveying member 230 at the unloading station, the second carrier 210 moves again to the loading station. During the process of ascending to the loading station, the second carrier 210 lifts the pallet 400 on the auxiliary carrier 240 and places it on its first supporting surface, either leaving the auxiliary carrier 240 empty or raising it to a position where it can jointly support the pallet 400 on the auxiliary carrier 240. The auxiliary carrier 240 then moves to the avoidance position via the auxiliary driving member, without affecting the downward movement of the second carrier 210 and the pallets 400 on it. The above process is repeated to achieve uninterrupted unloading of the tray 400 .

[0057] The intermediate position of the second carrier 210 actually includes multiple positions. The second carrier 210 is lowered sequentially based on the number of pallets 400 that the second carrier 210 can actually carry or the preset number of pallets 400 that the second carrier 210 can carry, ensuring that the conveyor mechanism 300 can sequentially stack multiple pallets 400 on the second carrier 210 at the loading station. The material unloading device disclosed in the present utility model achieves uninterrupted unloading of pallets 400 through the provision of the auxiliary carrier 240, ensuring production efficiency and a simple structure.

[0058] The first pallet conveyor assembly 100, the second pallet conveyor assembly 200, and the transmission mechanism 300 can all be mounted on the ground or on a rack via a bracket. The first lifting member 120 and the second lifting member 220 can specifically be a lifting screw mechanism, a cylinder slider mechanism, etc. The first transmission member 130 and the second transmission member 230 can be conveyor belts.

[0059] Combine Figure 1 and Figure 6 Typically, the first conveyor 130 has two stations that can simultaneously hold two groups of pallets 400. One station serves as a preparation station, and the other as a loading station. The first conveyor 130 drives the pallets 400 from the preparation station to the loading station to ensure a continuous supply of pallets 400. The second conveyor 230 has two stations that can simultaneously hold two groups of pallets 400. One station serves as an unloading station, and the other serves as a docking station for connecting to downstream equipment. The second conveyor 230 drives the pallets 400 from the unloading station to the docking station.

[0060] In addition, a sensor can be provided through the bracket to detect whether a pallet 400 is received at the loading station. When the arrival of the pallet 400 is detected, the second supporting member 210 is driven downward by the second lifting member 220 .

[0061] In order to ensure the accuracy of the material placement position on the pallet 400, taking the case where the pallet 400 is placed with materials at the loading station as an example, the second pallet conveying assembly 200 disclosed in the utility model also includes a centering positioning assembly, which is used to center the pallet 400 located at the loading station along two directions perpendicular to each other. After the positioning is completed, the material is loaded onto the pallet 400. After the pallet 400 is loaded, it is driven downward by the second carrier 210, and the new pallet 400 is transported to the loading station by the transmission mechanism 300 for the next round of pallet 400 positioning and material loading.

[0062] Specifically, combined Figure 3 and Figure 4 The centering positioning assembly includes a reference positioning plate 251, a first positioning baffle 250 and a first positioning motor. The first positioning baffle 250 is arranged at the output end of the first positioning motor, and the first positioning motor is used to push the first positioning baffle 250 in a direction close to or away from the reference positioning plate 251. The tray 400 is located between the reference positioning plate 251 and the first positioning baffle 250. The reference positioning plate 251 and the first positioning baffle 250 are used to press and position the tray 400 on both sides along the first direction.

[0063] In addition, the centering positioning assembly also includes two second positioning baffles 252 and two second positioning motors. The second positioning baffles 252 are respectively arranged at the output ends of the second positioning motors, and the second positioning motors are used to push the corresponding second positioning baffles 252 to move closer to or away from each other. The tray 400 is located between the two second positioning baffles 252. The two second positioning baffles 252 are used to press and position the two sides of the tray 400 along the second direction. The first direction and the second direction are perpendicular, and the second direction and the second direction are combined. Figure 2 , that is, the first and second positioning stops 250, 252 move perpendicularly to each other, respectively positioning the pallet 400 in its length and width. The combined use of the reference positioning plate 251, the first and second positioning stops 250, 252 allows for calibration of pallets 400 of varying sizes, effectively ensuring the accuracy of the pallet's 400 position and, consequently, the placement of materials.

[0064] A protrusion is provided on the edge of the bearing surface of the tray 400. The protrusion can be used for pressing and positioning by the centering positioning component and for adsorption and transportation by the transmission mechanism 300. In addition, it can also prevent the material in the tray 400 from falling.

[0065] In a specific embodiment, combined with Figure 2 The second lifting member 220 and the auxiliary support member 240 are respectively mounted on either side of the pallet 400 at the loading station via brackets. The reference positioning plate 251 and the second lifting member 220 are mounted on the same side of the pallet 400 and on the same bracket. The first positioning motor and the auxiliary support member 240 are also mounted on the same side of the pallet 400 and on the same bracket. By adjusting the mounting position of the auxiliary drive member on the bracket, the auxiliary support member 240 can be adapted to assist in supporting pallets 400 of different sizes.

[0066] Combine Figure 2 and Figure 3 The second carrier 210 includes at least two first support members, each of which constitutes a first bearing surface. The auxiliary carrier 240 includes at least two second support members, each of which constitutes a second bearing surface. When the auxiliary carrier 240 is in the bearing position, the first support members and the second support members are staggered along the lifting direction of the second lifting member 220, so that when the first support member rises and moves from the unloading station to the loading station, it can be staggered with the auxiliary carrier 240 and correspondingly support the pallet 400 located on the auxiliary support member.

[0067] The auxiliary driving parts include but are not limited to cylinders, motors, etc. The position movement of the auxiliary supporting part 240 between the supporting 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.

[0068] In addition to being arranged on the same bracket as the first positioning motor, the auxiliary carrier 240 can also be arranged on the same bracket as the second positioning motor. Correspondingly, the auxiliary carrier 240 is also arranged in two groups and supported by the two ends of the tray 400 respectively.

[0069] In some embodiments, the transfer station and the loading station are on the same horizontal plane, and the transfer mechanism 300 includes a first guide rail, a sliding bracket, and a first suction cup. The two ends of the first guide rail extend to the transfer station and the loading station respectively. The sliding bracket is movably arranged on the first guide rail, and the first suction cup is arranged on the sliding bracket for sucking the tray 400. Figure 1 The sliding bracket can be in an I-shape, so that the suction cup can respectively adsorb the four corners of the tray 400.

[0070] The material detection equipment disclosed in the present invention includes a material transfer mechanism 500 and the above-mentioned material unloading device. The material transfer mechanism 500 is used to transfer materials from a detection station or other positions to a pallet 400 at a loading station or a loading station. Since it includes the above-mentioned material unloading device, it also has the above-mentioned structure and beneficial effects. Other structures refer to the existing technology and will not be repeated here.

[0071] In some embodiments, combined Figure 7 The material transfer mechanism 500 includes a second guide rail 520 and a manipulator 510. One end of the second guide rail 520 extends to the loading station or the loading station to load the material onto the tray 400 located there. The manipulator 510 is slidably mounted on and can slide along the second guide rail 520. The manipulator 510 is provided with a second suction cup 511 and / or a support plate 512. The second suction cup 511 can absorb the upper surface of the material, and the support plate 512 can support the bottom of the material to prevent it from falling.

[0072] 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.
