[0121] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0122] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0123] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0124] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0125] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0126] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0127] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0128] Figure 1 This is a schematic diagram of a pallet loading and unloading system according to one embodiment of the present disclosure.
[0129] like Figure 1 As shown, the pallet loading and unloading system of this disclosure can realize the loading and unloading of pallets. Specifically, the pallet loading and unloading system of this disclosure may include: a loading hopper 100, a loading lifting device 200, a tray separating device 300, a positioning device 400, a tray collecting device 500, a unloading lifting device 600, and an unloading hopper 700, etc.
[0130] The feeding bin 100 is used to receive stacked pallets. Specifically, the feeding bin 100 can be docked with an AGV vehicle, so that the AGV vehicle can place stacked pallets into the feeding bin 100.
[0131] The pallets in the feeding hopper 100 disclosed herein can be empty pallets or pallets filled with materials, and this disclosure does not limit them.
[0132] Figure 2 This is a structural schematic diagram of the loading bin and loading lifting device of a pallet loading and unloading system according to one embodiment of the present disclosure. Figure 3 and Figure 4 This is a structural diagram of the loading bin and loading lifting device of a pallet loading and unloading system according to one embodiment of the present disclosure at different angles.
[0133] like Figures 2 to 4 As shown, the feeding hopper 100 of this disclosure may include components such as a feeding base plate 110, a left support plate 120, a right support plate 130, a left conveying device 140, and a right conveying device 150.
[0134] The feeding base plate 110 can be formed as a single integral structure or as a separate structure. Figures 2 to 4In the illustrated embodiment, the feeding base plate 110 is formed as a separate structure. In other words, the feeding hopper 100 of this disclosure may include two feeding base plates 110.
[0135] The left support plate 120 is slidably disposed on the feeding base plate 110; the right support plate 130 is also slidably disposed on the feeding base plate 110, and the left support plate 120 and the right support plate 130 are configured to be able to approach or move away from each other; thus, the feeding hopper 100 of this disclosure can accommodate trays of different sizes.
[0136] Those skilled in the art should know that the left support plate 120 and the right support plate 130 of this disclosure can be fixed on the feeding base plate 110. At this time, the feeding hopper 100 can only feed pallets of a certain size.
[0137] The left support plate 120 and right support plate 130 of this disclosure can be manually driven so that they can move relative to the loading base plate 110. Alternatively, the left support plate 120 and right support plate 130 can also be driven and moved by a linear motion mechanism. When the distance between the left support plate 120 and right support plate 130 is approximately the same as the size of the pallet, the left support plate 120 and right support plate 130 can be fixed to the loading base plate 110.
[0138] The left conveying device 140 is disposed on the left support plate 120; the right conveying device 150 is disposed on the right support plate 130; in a preferred embodiment, the left conveying device 140 and the right conveying device 150 can be belt conveying devices, thereby enabling the AGV to place stacked pallets on the left conveying device 140 and the right conveying device 150 so that the stacked pallets can be supported and conveyed by the left conveying device 140 and the right conveying device 150.
[0139] In other words, the AGV may not place the stacked pallets in the precise position. In this case, the stacked pallets can be transported to the lifting position by the left conveyor 140 and the right conveyor 150.
[0140] In this disclosure, a left baffle 160 is provided on the left support plate 120; and / or a right baffle 170 is provided on the right support plate 130. Thus, when the stacked pallets of this disclosure are lifted by the loading lifting device 200, the left baffle 160 and the right baffle 170 can limit the pallets, thereby preventing the stacked pallets from tipping over.
[0141] The loading lifting device 200 is used to lift the stacked pallets in the loading hopper 100; in a specific embodiment, the loading lifting device 200 includes a vertical plate 210, a loading lifting drive device 220, and a loading bracket 230, etc.
[0142] The upright plate 210 of this disclosure is set generally vertically, and the loading lifting drive device 220 is set on the upright plate 210; the loading bracket 230 is slidably set on the upright plate 210, wherein the loading bracket 230 is used to support stacked pallets, and the loading lifting drive device 220 is used to drive the loading bracket 230 to produce lifting movement.
[0143] In a preferred embodiment, the feeding lifting drive device 220 can be a ball screw structure driven by a motor. In this case, the feeding bracket 230 can be fixedly connected to the nut of the ball screw structure, so that the feeding bracket 230 can generate vertical movement.
[0144] In actual use, the loading tray 230 is located between the left support plate 120 and the right support plate 130. When the AGV trolley places the pallet on the left conveyor 140 and the right conveyor 150, the loading tray 230 does not contact the stacked pallets. Therefore, the loading tray 230 will not affect the horizontal movement of the stacked pallets.
[0145] Figure 5 This is a structural schematic diagram of the loading bin, loading lifting device, and tray separating device of a pallet loading and unloading system according to one embodiment of the present disclosure. Figure 6 This is a schematic diagram of the structure of a tray sorting device in a tray loading and unloading system according to one embodiment of the present disclosure.
[0146] The tray separating device 300 is used to separate the stacked pallets lifted by the loading lifting device 200, and the tray separating device 300 is also used to transport the separated pallets.
[0147] Specifically, the tray separating device 300 disclosed herein includes: a tray base plate 310, a first front side crossbeam 320, a first rear side crossbeam 330, a first front conveying assembly 340, a first rear conveying assembly 350, a first tray separating assembly 360, and a second tray separating assembly 370, etc.
[0148] The tray base plate 310 of this disclosure has a through hole, through which stacked trays can pass and be positioned above the tray base plate 310.
[0149] The first front crossbeam 320 is slidably disposed on the tray base plate 310; the first rear crossbeam 330 is slidably disposed on the tray base plate 310, and the first front crossbeam 320 and the first rear crossbeam 330 are configured to be able to approach or move away from each other; thus, the distance between the first front crossbeam 320 and the first rear crossbeam 330 of this disclosure is variable.
[0150] In a preferred embodiment, a slide cylinder is provided on the base plate 310 of the tray. The two ends of the first front crossbeam 320 are respectively disposed on two slide cylinders, and the two ends of the first rear crossbeam 330 are respectively disposed on two other slide cylinders. Thus, the distance between the first front crossbeam 320 and the first rear crossbeam 330 of this disclosure can be adjusted by controlling the operation of the slide cylinder.
[0151] The first front conveying assembly 340 is disposed on the first front side crossbeam 320; the first rear conveying assembly 350 is disposed on the first rear side crossbeam 330; in a preferred embodiment, the first front conveying assembly 340 and the first rear conveying assembly 350 can be belt conveyors.
[0152] Since the distance between the first front crossbeam 320 and the first rear crossbeam 330 is adjustable, the distance between the first front conveying assembly 340 and the first rear conveying assembly 350 is also adjustable. Specifically, when the distance between the first front conveying assembly 340 and the first rear conveying assembly 350 allows the pallet to pass through, that is, when the distance between the first front conveying assembly 340 and the first rear conveying assembly 350 is greater than the size of the pallet, the pallet can be divided by the first tray-separating assembly 360 and the second tray-separating assembly 370 and driven above the first front conveying assembly 340 and the first rear conveying assembly 350. At this time, the distance between the first front conveying assembly 340 and the first rear conveying assembly 350 will become smaller, thereby enabling the first front conveying assembly 340 and the first rear conveying assembly 350 to carry and convey the pallet.
[0153] The first tray-separating component 360 is disposed on the tray-separating base plate 310, and the second tray-separating component 370 is disposed on the tray-separating base plate 310. The first tray-separating component 360 and the second tray-separating component 370 cooperate to separate the stacked pallets lifted by the loading lifting device 200.
[0154] Figure 7 This is a schematic diagram of the structure of the first tray-separating assembly of a tray-separating device in a tray loading and unloading system according to an embodiment of the present disclosure. Figure 8 This is a structural schematic diagram of the first tray-separating assembly of a tray-separating device in a tray loading and unloading system according to one embodiment of the present disclosure, from another angle.
[0155] In a preferred embodiment, the first tray assembly 360 and the second tray assembly 370 have identical structures and are symmetrically arranged. Preferably, along the direction of tray movement, the second tray assembly 370 is located downstream of the first tray assembly 360. The structure of the first tray assembly 360 and the second tray assembly 370 will be described below using the first tray assembly 360 as an example.
[0156] like Figure 7As shown, the first dividing plate assembly 360 of this disclosure includes a dividing plate support plate 361, a first dividing plate support frame 362, a first dividing plate drive device 363, a pressure plate component 364, a second dividing plate drive device 365, a dividing plate intermediate plate 366, a third dividing plate drive device 367, and a dividing plate component 368, etc.
[0157] The tray support plate 361 is fixed to the tray base plate 310; the first tray support frame 362 is disposed on the tray support plate 361; the first tray drive device 363 is disposed on the first tray support frame 362; specifically, the first tray support frame 362 of this disclosure is disposed approximately vertically, at which time the lower end of the first tray support frame 362 is fixed to the tray support plate 361, and the upper end of the first tray support frame 362 is provided with the first tray drive device 363.
[0158] The pressure plate component 364 is disposed on the first disc drive device 363 so that the pressure plate component 364 is driven to move by the first disc drive device 363 so that the pressure plate component 364 can approach or move away from the tray in the horizontal direction; in a specific embodiment, the first disc drive device 363 of this disclosure can be a cylinder, thereby the first disc drive device 363 can drive the pressure plate component 364 to move horizontally.
[0159] The second disk drive device 365 is disposed on the disk support plate 361; the disk intermediate plate 366 is disposed on the second disk drive device 365, and the second disk drive device 365 is used to drive the disk intermediate plate 366 to rise and fall; in a specific embodiment, the second disk drive device 365 can be a cylinder, such as a slide cylinder.
[0160] See again Figure 7 The dividing plate 361 of this disclosure may be provided with a column, and a slider may be provided on the column. The two ends of the dividing plate 366 are provided with guide rails, which are slidably disposed on the slider. Thus, the movement of the dividing plate 366 in the vertical direction can be guided.
[0161] The third tray drive device 367 is disposed on the tray intermediate plate 366; the tray component 368 is disposed on the third tray drive device 367 so that the third tray drive device 367 drives the tray component 368 to move so that the tray component 368 can approach or move away from the tray in the horizontal direction.
[0162] In one specific embodiment, the third disc drive device 367 can be a cylinder, thereby enabling the third disc drive device 367 to drive the disc component 368 to move horizontally.
[0163] When the tray-separating device of this disclosure is in use, the first tray-separating drive device 363 and the third tray-separating drive device 367 can be controlled to move, thereby causing the pressing plate component 364 and the tray-separating component 368 to approach and contact the tray. At this time, the tray-separating component 368 will be able to hold the uppermost tray, and the pressing plate component 364 will be able to hold the tray adjacent to the uppermost tray. Then, the second tray-separating drive device 365 moves, which can lift the uppermost tray. At this time, the tray adjacent to the uppermost tray from below will remain in the same position, thereby realizing the tray-separating action.
[0164] After the tray is lifted, the distance between the first front conveyor assembly 340 and the first rear conveyor assembly 350 will decrease. At this time, the second tray-splitting drive device 365 drives the tray to descend, and the tray will be placed on the first front conveyor assembly 340 and the first rear conveyor assembly 350. Then, the first front conveyor assembly 340 and the first rear conveyor assembly 350 will transport the tray to the positioning device 400.
[0165] Figure 9 This is a schematic diagram of the positioning device of a pallet loading and unloading system according to one embodiment of the present disclosure. Figure 10 and Figure 11 This is a structural schematic diagram of the positioning device of a pallet loading and unloading system according to one embodiment of the present disclosure at different angles.
[0166] like Figures 9 to 11 As shown, the positioning device 400 of this disclosure is used to receive the pallet conveyed by the tray distribution device 300, and the pallet is supported and positioned by the positioning device 400; the positioning device 400 is also used to convey the pallet.
[0167] In other words, once the pallet is transferred to the positioning device 400, the positioning device 400 can continue to transport the pallet and deliver it to the preset position of the positioning device 400. Then, the positioning device 400 will support and position the pallet. At this time, the materials in the pallet can be transported to the automated production line by automated operating equipment such as robotic arms, or the products on the automated production line can be transported to the pallet.
[0168] Specifically, the positioning device 400 disclosed herein may include components such as a positioning base plate 410, a second front crossbeam 420, a second rear crossbeam 430, a second front conveying assembly 440, a second rear conveying assembly 450, a blocking device 460, a lifting assembly 470, and a cover plate 480.
[0169] The second front crossbeam 420 is disposed on the positioning base plate 410. Preferably, the second front crossbeam 420 can be fixed to the positioning base plate 410. The second rear crossbeam 430 is disposed on the positioning base plate 410. Preferably, the second rear crossbeam 430 is slidably disposed on the positioning base plate 410. The second front crossbeam 420 and the second rear crossbeam 430 are configured to be able to approach or move away from each other. Thus, the distance between the second front crossbeam 420 and the second rear crossbeam 430 of this disclosure is variable.
[0170] The second front conveying assembly 440 is disposed on the second front side crossbeam 420; the second rear conveying assembly 450 is disposed on the second rear side crossbeam 430; in a preferred embodiment, the second front conveying assembly 440 and the second rear conveying assembly 450 can be belt conveyors.
[0171] Since the second front conveyor assembly 440 and the second rear conveyor assembly 450 are always located below the pallet, it is only necessary to adjust the distance between the second front conveyor assembly 440 and the second rear conveyor assembly 450 to the size of the pallet or slightly larger than the size of the pallet.
[0172] A blocking device 460 is disposed on the positioning base plate 410 for blocking the pallet. In one specific embodiment, the blocking device 460 includes a blocking cylinder and a blocking plate disposed on the blocking cylinder. The blocking cylinder is capable of lifting and lowering; it rises when the pallet needs to be blocked and lowers when the pallet needs to be released. The blocking plate contacts the pallet to block it, thereby confining the pallet to a preset position.
[0173] The lifting assembly 470 is disposed on the positioning base plate 410 and is used to lift the tray blocked by the blocking device 460. The lifting assembly 470 of this disclosure may include a lifting cylinder and a lifting plate disposed on the lifting cylinder, which supports and lifts the tray from below.
[0174] A cover plate 480 is disposed on a positioning base plate 410 so that the tray is positioned between the lifting assembly 470 and the cover plate 480. That is, the cover plate 480 is always located above the tray. In a preferred embodiment, the cover plate 480 has a through hole in the middle, the size of which is smaller than the size of the tray but larger than the size of the area where materials are placed inside the tray. This allows components such as robotic arms to pass through the cover plate 480 to remove materials from the tray or place materials inside the tray.
[0175] Figure 12 This is a structural schematic diagram of the unloading bin, unloading lifting device, and pallet collection device of a pallet loading and unloading system according to one embodiment of the present disclosure. Figure 13 This is a schematic diagram of the structure of a pallet collection device in a pallet loading and unloading system according to one embodiment of the present disclosure. Figure 14This is a schematic diagram of the structure of the first tray assembly 560 of the tray collection device of a tray loading and unloading system according to one embodiment of the present disclosure.
[0176] The tray collecting device 500 is used to collect the pallets conveyed by the positioning device 400 and stack the pallets; the unloading lifting device 600 is used to receive the pallets stacked by the tray collecting device 500 and lower the stacked pallets to the unloading hopper 700; the unloading hopper 700 is used to receive the stacked pallets conveyed by the unloading lifting device 600.
[0177] In a preferred embodiment, the unloading lifting device 600 has the same structure as the loading lifting device 200; the unloading hopper 700 has the same structure as the loading hopper 100. The structures of the unloading lifting device 600 and the unloading hopper 700 will not be described in detail here.
[0178] The tray collecting device 500 and the tray distributing device 300 disclosed herein have a generally similar structure, which will be described below in conjunction with... Figure 13 and Figure 14 The structure of the collection tray device 500 is described.
[0179] Specifically, such as Figures 12 to 14 As shown, the tray collection device 500 of this disclosure includes components such as: tray base plate 510, third front side crossbeam 520, third rear side crossbeam 530, third front conveying assembly 540, third rear conveying assembly 550, first tray assembly 560 and second tray assembly 570.
[0180] The tray base plate 510 of this disclosure has a through hole, through which stacked trays can pass and be located below the tray base plate 510.
[0181] The third front crossbeam 520 is slidably disposed on the tray base plate 510; the third rear crossbeam 530 is slidably disposed on the tray base plate 510, and the third front crossbeam 520 and the third rear crossbeam 530 are configured to be able to approach or move away from each other; thus, the distance between the third front crossbeam 520 and the third rear crossbeam 530 of this disclosure is variable.
[0182] In a preferred embodiment, a slide cylinder is provided on the tray base plate 510, and the two ends of the third front crossbeam 520 are respectively provided on two slide cylinders, and the two ends of the third rear crossbeam 530 are respectively provided on two other slide cylinders. Thus, the distance between the third front crossbeam 520 and the third rear crossbeam 530 of this disclosure can be adjusted by controlling the operation of the slide cylinder.
[0183] The third front conveying assembly 540 is disposed on the third front side crossbeam 520; the third rear conveying assembly 550 is disposed on the third rear side crossbeam 530; in a preferred embodiment, the third front conveying assembly 540 and the third rear conveying assembly 550 can be belt conveyors.
[0184] Since the distance between the third front crossbeam 520 and the third rear crossbeam 530 is adjustable, the distance between the third front conveying assembly 540 and the third rear conveying assembly 550 is also adjustable. Specifically, when the distance between the third front conveying assembly 540 and the third rear conveying assembly 550 allows the pallet to pass through, that is, when the distance between the third front conveying assembly 540 and the third rear conveying assembly 550 is greater than the size of the pallet, the pallet can be collected by the first tray-collecting assembly 560 and the second tray-collecting assembly 570 and driven to be below the third front conveying assembly 540 and the third rear conveying assembly 550. At this time, the distance between the third front conveying assembly 540 and the third rear conveying assembly 550 will become smaller, thereby enabling the third front conveying assembly 540 and the third rear conveying assembly 550 to carry and convey the next pallet.
[0185] A first tray assembly 560 is disposed on a tray base plate 510, and a second tray assembly 570 is disposed on the tray base plate 510. The first tray assembly 560 and the second tray assembly 570 cooperate to hold the trays and stack them together. Preferably, along the direction of movement of the trays, the first tray assembly 560 is located upstream of the second tray assembly 570.
[0186] Unlike the tray distribution device, the tray collection device of this disclosure also includes a stop 580 located near the second tray collection assembly 570 to stop the tray, thereby facilitating tray collection by the tray collection device.
[0187] like Figure 14 As shown, the first disk assembly 560 and the second disk assembly 570 of this disclosure have the same structure. The following description uses the first disk assembly 560 as an example.
[0188] Unlike the first tray separating device, the first tray collecting assembly 560 of this disclosure does not include the first tray separating support frame, the first tray separating drive device, and the pressing plate component. In other words, the first tray collecting assembly 560 of this disclosure may include components such as: a tray collecting support plate 561, a second tray collecting drive device 565, a tray collecting intermediate plate 566, a third tray collecting drive device 567, and a tray collecting component 568.
[0189] The tray support plate 561 is fixed to the tray base plate 510; the second tray drive device 565 is disposed on the tray support plate 561; the tray intermediate plate 566 is disposed on the second tray drive device 565, and the second tray drive device 565 is used to drive the tray intermediate plate 566 to rise and fall; in a specific embodiment, the second tray drive device 565 can be a cylinder, such as a slide cylinder.
[0190] The tray support plate 561 of this disclosure may be provided with a column, and a slider may be provided on the column. Guide rails are provided at both ends of the tray intermediate plate 566, and the guide rails are slidably provided on the slider. Thus, the movement of the tray intermediate plate 566 of this disclosure in the vertical direction can be guided.
[0191] The third tray drive device 567 is disposed on the tray intermediate plate 566; the tray component 568 is disposed on the third tray drive device 567 so that the third tray drive device 567 drives the tray component 568 to move so that the tray component 568 can approach or move away from the tray in the horizontal direction.
[0192] In one specific embodiment, the third disk drive device 567 can be a cylinder, thereby enabling the third disk drive device 567 to drive the disk component 568 to move horizontally.
[0193] When the tray collection device of this disclosure is in use, the second tray collection drive device 565 can be controlled to rise first, and then the third tray collection drive device 567 can be controlled to move, so that the tray collection component 568 holds the tray. Then, the distance between the third front conveying component 540 and the third rear conveying component 550 will increase. Next, the second tray collection drive device 565 is controlled to descend to place the tray onto the unloading lifting device 600, so that the tray is in a stacked state.
[0194] Next, the distance between the third front conveyor assembly 540 and the third rear conveyor assembly 550 will decrease to receive the next pallet.
[0195] Based on the above structure, the pallet loading and unloading system disclosed herein can automatically realize the pallet conveying, clamping and positioning, pallet sorting, collection and return operations in a fully automatic manner without manual intervention, ensuring the accuracy and stability of operation.
