[0002] In the machining process, silos are being used more and more widely to facilitate the supply of materials.

[0003] In related technologies, the hopper is equipped with a receiving cavity, and the receiving cavity is equipped with a liftable support plate. Stacks of material trays are stacked on the support plate. When the hopper is working, each time the grabbing module grabs a material tray from the top of the material tray stack, the support plate can move upward a certain distance to ensure that the material tray at the top of the material tray stack always remains at the same horizontal height.

[0004] However, during the process of the gripping module gripping the topmost tray of trays, the topmost tray will cause the next tray to shift, thus affecting the gripping module's gripping of subsequent trays. Utility Model Content

[0036] The following is for reference. Figures 1 to 6 The material silo of this application is described in detail.

[0037] refer to Figure 1 and Figure 2According to an embodiment of the present invention, the hopper includes a hopper body 100, a first bearing module 200, a lifting module 300, and a positioning module 400. The hopper body 100 has a vertically extending first storage cavity 101, the upper end of which has an opening communicating with the outside. The first bearing module 200 is slidably disposed in the first storage cavity 101 in the vertical direction and is used to bear the material tray stack. The lifting module 300 is connected to the first bearing module 200 and is used to drive the first bearing module 200 to perform lifting and lowering movements. The positioning module 400 is disposed at the opening and is used to horizontally position the uppermost material tray of the material tray stack.

[0038] For example, such as Figure 1 and Figure 2 As shown, the hopper includes a hopper body 100, a first bearing module 200, a lifting module 300, and a positioning module 400. The hopper body 100 has a first storage cavity 101 with a vertically extending strip. The upper end of the first storage cavity 101 has an opening that communicates with the outside. The first bearing module 200 is located in the first storage cavity 101 and is slidably arranged in the vertical direction. The output end of the lifting module 300 is connected to the first bearing module 200 for transmission. The lifting module 300 is used to drive the first bearing module 200 to perform lifting and lowering movements. The positioning module 400 is located at the opening.

[0039] It should be noted that when the silo is working, the pallet stack is supported on the first support module 200, and the top pallet of the pallet stack is located at the cavity opening. After the material picking device removes the top pallet of the pallet stack from the cavity opening each time, the first support module 200 can drive the pallet stack to move upward a certain distance under the drive of the lifting module 300 to ensure that the top pallet of the pallet stack is always at the cavity opening. However, when the material picking device picks up the top pallet of the pallet stack, the top pallet of the pallet stack will drive the next pallet of the pallet stack to move, thereby causing the next pallet of the pallet stack to be horizontally offset. When the material picking device picks up the pallet stack for subsequent material, it is difficult for the material picking device to accurately grab the top pallet of the pallet stack.

[0040] It is understood that in the hopper of this application, by setting a positioning module 400 at the cavity opening, each time the lifting module 300 drives the first bearing module 200 to move upward, so that the uppermost material tray of the material tray stack on the first bearing module 200 moves to the cavity opening, the positioning module 400 can horizontally position the uppermost material tray of the material tray stack in the horizontal direction to correct the offset of the uppermost material tray of the material tray stack, so that the subsequent material picking device can accurately pick up the material tray of the uppermost material tray stack.

[0041] In some embodiments of this utility model, the hopper body 100 includes a positioning element 110; the positioning module 400 includes a first driver 410 and a movable element 420, the movable element 420 and the positioning element 110 are spaced apart along a first horizontal direction, and a positioning area for positioning the tray is formed between the movable element 420 and the positioning element 110. The first driver 410 is connected to the movable element 420 and is used to drive the movable element 420 to move closer to or away from the positioning element 110 along the first horizontal direction.

[0042] For example, such as Figures 1 to 3 As shown, the storage chamber 100 includes a positioning member 110, which is located on the front side of the first storage cavity 101. The positioning module 400 includes a first driver 410 and a movable member 420. The first driver 410 is mounted on the storage chamber 100, and the movable member 420 is located at the cavity opening and behind the positioning member 110. A positioning area is formed between the movable member 420 and the positioning member 110. The output end of the first driver 410 is connected to the movable member 420.

[0043] Furthermore, when the lifting module 300 drives the first bearing module 200 to move upward, so that the uppermost tray of the tray stack moves to the cavity opening, the uppermost tray of the tray end is just located in the positioning area. At this time, the first driver 410 drives the movable part 420 to move forward and approach the positioning part 110, so that the movable part 420 cooperates with the positioning part 110 to position the uppermost tray of the tray stack in the front-back direction.

[0044] It should be noted that, due to the limited space inside the silo 100, if the first driver 410 is placed inside the silo 100, the first driver 410 is likely to interfere with the material stack.

[0045] Based on the above problems, in some embodiments of this utility model, the first driver 410 is disposed on the outer cavity wall of the first storage cavity 101, and the movable member 420 includes a driving part 421, a transmission part 422 and an abutment part 423 connected in sequence. The driving part 421, the transmission part 422 and the abutment part 423 together define a relief groove 420a. The edge of the cavity opening passes through the relief groove 420a. The driving part 421 is located outside the edge and is connected to the output end of the first driver 410. The abutment part 423 is located inside the edge and forms a positioning area with the positioning member 110.

[0046] For example, such as Figures 1 to 3As shown, the first driver 410 can be disposed on the right side cavity wall of the first storage cavity 101. The movable member 420 includes a driving part 421, a transmission part 422, and an abutment part 423. The transmission part 422 extends in the left-right direction. The driving part 421 is connected to the lower right end of the transmission part 422, and the abutment part 423 is connected to the lower left end of the transmission part 422. The driving part 421, the transmission part 422, and the abutment part 423 together define a downward-facing clearance groove 420a. The upper end of the right side cavity wall of the first storage cavity 101 passes through the clearance groove 420a. The abutment part 423 is located inside the first storage cavity 101, and the driving part 421 is located outside the cavity of the first storage cavity 101. The output end of the first driver 410 is connected to the driving part 421.

[0047] Furthermore, under the drive of the first driver 410, the drive unit 421 can move in the front-back direction, so that the drive unit 421 can drive the abutment unit 423 to move closer to or away from the positioning member 110 in the front-back direction through the transmission unit 422.

[0048] It is understandable that, since the drive part 421, the transmission part 422 and the abutment part 423 together define the clearance groove 420a, the entire movable part 420 presents a downward-opening U-shape. Thus, while ensuring that the first driver 410 is located outside the cavity of the first storage cavity 101, the first driver 410 can still normally drive the abutment part 423 to move closer to or away from the positioning member 110 in the front-back direction. At the same time, since the first driver 410 is located outside the cavity of the first storage cavity 101, it can ensure that there is enough space in the first storage cavity 101 to accommodate the pallet stack, and can reduce the interference of the first driver 410 on the pallet stack in the first storage cavity 101.

[0049] In some embodiments of this utility model, two sets of positioning components 110 and positioning modules 400 are provided along the second horizontal direction. The two sets of positioning components 110 and positioning modules 400 are used to cooperate in positioning the same tray. The second horizontal direction is set at a certain angle from the first horizontal direction.

[0050] For example, such as Figure 1 and Figure 2 As shown, two sets of positioning components 110 and positioning modules 400 are provided in the left and right directions respectively. The two positioning components 110 are located on the front side of the first storage cavity 101 and are distributed in the left and right directions. The two positioning modules 400 are respectively located on the left and right sides of the first storage cavity 101.

[0051] Understandably, when the first bearing module 200 moves the pallet stack upwards until the top pallet of the pallet stack moves to the cavity opening, the left positioning module 400 can work with the left positioning component 110 to position the left end of the top pallet in the front-back direction, and the right positioning module 400 can work with the right positioning component 110 to position the right end of the top pallet in the front-back direction. By setting two sets of positioning components 110 and positioning modules 400, the positioning of the top pallet of the pallet stack can be made more accurate.

[0052] In some embodiments of this utility model, the hopper further includes a second bearing module 500, and the hopper body 100 is also provided with a second storage cavity 102. The second storage cavity 102 is located on one side of the first storage cavity 101 in the first horizontal direction and is connected to the first storage cavity 101. The side of the second storage cavity 102 away from the first storage cavity 101 is provided with a feed inlet 102a that communicates with the outside. The second bearing module 500 is located at the bottom of the second storage cavity 102. The second bearing module 500 includes a conveying structure for conveying pallet stacks into the first storage cavity 101.

[0053] For example, such as Figure 1 and Figure 2 As shown, the hopper also includes a second bearing module 500. The hopper body 100 is provided with a second storage cavity 102. The second storage cavity 102 is located behind the first storage cavity 101 and is connected to the first storage cavity 101. The rear end of the second storage cavity 102 is provided with a feed inlet 102a that communicates with the outside. The second bearing module 500 is located at the bottom of the second storage cavity 102. The second bearing module 500 includes a conveying structure.

[0054] Understandably, during the process of the material handling device handling the material stack in the first storage cavity 101, the operator can feed a new material stack through the feed inlet 102a into the second bearing module 500 of the second storage cavity 102. After the material stack in the first storage cavity 101 has been handled, the lifting module 300 can drive the first bearing module 200 to move downwards to be on the same horizontal plane as the second bearing module 500. At this time, under the conveying structure of the second bearing module 500, the material stack in the second storage cavity 102 moves onto the first bearing module 200 of the first storage cavity 101 to realize the material distribution of the material stack in the first storage cavity 101.

[0055] Understandably, the second storage cavity 102 allows workers to pre-place the pallets to be picked up by the material retrieval device within it; and the conveying structure in the second bearing module 500 enables the pallets in the second storage cavity 102 to be automatically transferred to the first bearing module 200 of the first storage cavity 101 in a timely manner, thereby improving the overall material supply speed of the silo.

[0056] In some embodiments of this utility model, the first bearing module 200 includes a first mounting frame 210, a first motor 220, and a first conveyor belt 230. The first conveyor belt 230 is wound around the first mounting frame 210 and extends along a first horizontal direction. The first motor 220 is mounted on the first mounting frame 210 and is connected to the first conveyor belt 230 for transmission. Under the drive of the first motor 220, the first conveyor belt 230 can receive the pallet stack output by the conveying structure and drive the pallet stack to move along the first horizontal direction. The output end of the lifting module 300 is connected to the first mounting frame 210.

[0057] For example, such as Figure 4 As shown, the first load-bearing module 200 includes a first mounting frame 210, a first motor 220, and a first conveyor belt 230. The first conveyor belt 230 is wound around the first mounting frame 210 and extends in the front-to-back direction. The first motor 220 is mounted on the first mounting frame 210 and is connected to the first conveyor belt 230 for transmission. The output end of the lifting module 300 is connected to the first mounting frame 210 and is used to drive the first mounting frame 210 to perform lifting movements.

[0058] Furthermore, during the process of the conveying structure transporting the pallet stack in the second storage cavity 102 forward to the first storage cavity 101, the front end of the pallet stack moves onto the first conveyor belt 230. Driven by the first motor 220, the first conveyor belt 230 drives the pallet stack to move completely from the second storage cavity 102 to the first storage cavity 101.

[0059] It is understandable that the first conveyor belt 230 is configured to work with the conveying structure to smoothly transfer the pallet stack in the second storage cavity 102 to the first storage cavity 101.

[0060] In some embodiments of this utility model, the second bearing module 500 further includes a second mounting frame 510, and the conveying structure includes a second motor 520 and a second conveyor belt 530. The second conveyor belt 530 is wound around the second mounting frame 510 and extends along the first horizontal direction. The second motor 520 is mounted on the second mounting frame 510 and is connected to the second conveyor belt 530 for transmission. Under the drive of the second motor 520, the second conveyor belt 530 can transport the pallet stack it carries to the first storage cavity 101.

[0061] For example, such as Figure 4 As shown, the second bearing module 500 also includes a second mounting frame 510, and the conveying structure includes a second motor 520 and a second conveyor belt 530. The second conveyor belt 530 is wound around the second mounting frame 510 and extends in the front-rear direction. The second motor 520 is mounted on the second mounting frame 510 and is connected to the second conveyor belt 530 for transmission.

[0062] Then, when the worker places the pallet stack into the second storage cavity 102, the pallet stack is supported on the second conveyor belt 530. Driven by the second motor 520, the second conveyor belt 530 drives the pallet stack forward and moves the front end of the pallet stack onto the first conveyor belt 230. Driven by the first motor 220, the first conveyor belt 230 pulls the front end of the pallet stack forward, so that the first conveyor belt 230 can work in tandem with the second conveyor belt 530 to drive the pallet stack forward until the pallet stack is completely transferred from the second storage cavity 102 into the first storage cavity 101.

[0063] In some embodiments of this utility model, the first conveyor belt 230 and the second conveyor belt 530 are distributed along a second horizontal direction, the second horizontal direction is set at a certain angle from the first horizontal direction, and the first conveyor belt 230 and the second conveyor belt 530 are at least partially overlapped in the first horizontal direction.

[0064] For example, such as Figure 4 As shown, the first conveyor belt 230 and the second conveyor belt 530 both extend in the front-to-back direction, and the first conveyor belt 230 and the second conveyor belt 530 are staggered in the left-to-right direction.

[0065] It is understandable that, since both the first conveyor belt 230 and the second conveyor belt 530 extend in the front-back direction, by staggering the first conveyor belt 230 and the second conveyor belt 530 in the left-right direction, the probability of interference between the first conveyor belt 230 and the second conveyor belt 530 can be reduced, so as to avoid the first conveyor belt 230 colliding with the second conveyor belt 530 during the lifting and lowering movement following the first mounting frame 210. At the same time, the first conveyor belt 230 and the second conveyor belt 530 can be arranged more compactly in the front-back direction.

[0066] In a further embodiment of this utility model, reference is made to... Figure 4 The first conveyor belt 230 and the second conveyor belt 530 are distributed along the second horizontal direction, which is set at a certain angle to the first horizontal direction. In the first horizontal direction, the first conveyor belt 230 and the second conveyor belt 530 are at least partially overlapped.

[0067] It is understood that, in the first horizontal direction, the first conveyor belt 230 and the second conveyor belt 530 are arranged to overlap at least partially, so that the pallet stack can be fully supported on the first conveyor belt 230 before it is completely separated from the second conveyor belt 530, so that the pallet stack can be smoothly transferred from the second conveyor belt 530 to the first conveyor belt 230.

[0068] In some embodiments of this utility model, reference is made to Figure 4Two first conveyor belts 230 are spaced apart along the second horizontal direction, and two second conveyor belts 530 are spaced apart along the second horizontal direction. Along the second horizontal direction, the two first conveyor belts 230 are located between the two second conveyor belts 530.

[0069] It is understandable that by setting two first conveyor belts 230, the two first conveyor belts 230 can respectively support the horizontally opposite ends of the material tray stack, thereby improving the stability of the material tray stack supported by the first support module 200; by setting two second conveyor belts 530, the two second conveyor belts 530 can respectively support the horizontally opposite ends of the material tray stack, thereby improving the stability of the material tray stack supported by the second support module 500.

[0070] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 and Figure 5 The hopper also includes a blocking module 600, which includes a second driver 610 and a blocking plate 620. The second driver 610 is connected to the blocking plate 620 and is used to drive the blocking plate 620 to extend into the junction of the first storage cavity 101 and the second storage cavity 102, or to drive the blocking plate 620 to extend out of the junction of the first storage cavity 101 and the second storage cavity 102.

[0071] Understandably, when there are still trays in the first storage cavity 101, the second driver 610 can drive the baffle plate 620 to insert into the junction of the first storage cavity 101 and the second storage cavity 102 to prevent the tray stack in the second storage cavity 102 from entering the first storage cavity 101; when all the trays in the first storage cavity 101 are removed, the second driver 610 can drive the baffle plate 620 to extend out of the junction of the first storage cavity 101 and the second storage cavity 102, at which time the tray stack in the second storage cavity 102 can smoothly enter the first storage cavity 101.

[0072] In a further embodiment of this utility model, reference is made to... Figure 1 and Figure 2 There are two blocking modules 600, which are located on the left and right sides of the hopper respectively.

[0073] Understandably, by setting two blocking modules 600, the blocking effect on the pallet stacks in the second storage cavity 102 can be further improved.

[0074] In some embodiments of this utility model, reference is made to Figure 6The lifting module 300 includes a lifting frame 310, a guide frame 320, and a third driver 330. The guide frame 320 is provided with a vertically extending slide rail 321. The lifting frame 310 is slidably mounted on the slide rail 321 and connected to the first mounting frame 210. The third driver 330 is mounted on the guide frame 320 and is driven by the lifting frame 310. Under the drive of the third driver 330, the lifting frame 310 moves up and down along the slide rail 321, thereby driving the first mounting frame 210 to move up and down, thus realizing the lifting movement of the first bearing module 200.

[0075] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
