Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of transportation, and particularly relates to a plate taking and adjusting device based on dense stacking. BACKGROUND

The material types are also relatively many. The plate-shaped materials of different thicknesses and types are generally placed in a warehouse in a horizontal stacking manner. The bottom of the plate-shaped material is placed on the ground through a wooden tray. The wooden tray can not only prevent the direct contact between the ground and the plate-shaped material, causing the moisture and indentation of the plate-shaped material, but also facilitate the use of a forklift to transfer the whole stack of plate-shaped materials. When the plate-shaped material is delivered (delivery means that the plate-shaped material is delivered out of the warehouse according to the order of a customer), the forklift is used to transport the whole stack of plate-shaped materials out of the warehouse. For the case that a small amount of plate-shaped material is needed, the manual carrying manner is generally used to carry the plate-shaped material one by one to the forklift. The labor intensity is large, and when the plate-shaped material is stacked, the space for the forklift to travel needs to be reserved, so that the space utilization of the warehouse is low. SUMMARY

[0005] The opening size of the bottom of the shell is greater than the size of the plate-shaped material matched therewith. The open end of the bottom of the shell is connected with a closing and clamping sealing structure having the functions of expansion and closing. The closing and clamping sealing structure can form a clamping and sealing state with the plate-shaped material when the closing and clamping sealing structure is closed and clamped.

[0006] As a preferred plate taking and adjusting device based on dense stacking of the present application, the closing and clamping sealing structure comprises a rubber side plate and a sealing strip. The top of the rubber side plate is fixedly sealed relative to the bottom of the shell. The bottom of the rubber side plate is fixedly connected with the sealing strip.

[0007] As the plate taking device based on dense stacking of the application, the junction of the two adjacent rubber side plates is in the shape of a pointed herringbone.

[0008] As the plate taking device based on dense stacking of the application, the length of the sealing strip is greater than the length of the side of the plate-shaped material.

[0009] As the plate taking device based on dense stacking of the application, the internal space of the shell is greater than the plate and greater than or equal to the size of the bottom opening of the shell.

[0010] As the plate taking device based on dense stacking of the application, the top of the rubber side plate is fixedly connected with a hard frame, the top of the hard frame is fixedly connected with the bottom of the shell, and the four corners of the hard frame are arranged in the shape of a herringbone.

[0011] As the plate taking device based on dense stacking of the application, one end of the sealing strip is fixedly connected with a push plate, the outer side of the push plate is fixedly connected with a limiting block, the outer surface of the limiting block and one side surface of the push plate are slidably connected with the inner side of the end of the holding bracket, the central position of the holding bracket is fixedly connected with a power telescopic rod, the telescopic main shaft of the power telescopic rod is fixedly connected with one end of the push plate, and the holding bracket is fixedly connected with the surface of the shell through the connecting bracket.

[0012] As the plate taking device based on dense stacking of the application, the bottom inner side of the shell is fixedly connected with a plurality of inclined plates, and the inclined surface edge of the inclined plate is connected with the bottom inner opening edge of the shell.

[0013] As the plate taking device based on dense stacking of the application, the top of the shell is fixedly connected with a hanging bracket, the top of the hanging bracket is fixedly connected with a heavy-duty tension sensor, and the top of the heavy-duty tension sensor is fixedly connected with a hanging ear.

[0014] As the plate taking device based on dense stacking of the application, the part of the closing clamping sealing structure directly contacting with the plate-shaped material is not less than the thickness of three plate-shaped materials.

[0015] Compared with the prior art, the present application has the following advantages: the present application can transport plate-shaped materials without using a forklift, thereby improving the space utilization of the warehouse, reducing the storage cost, and avoiding the problem of excessive labor intensity without manual transportation; the shell is moved to the top of the target stacked plate-shaped material by the gantry robot, and then the shell is moved downward by the gantry robot, so that the shell engulfs part of the plate-shaped material, the plate-shaped material engulfed by the shell is the required number of plate-shaped materials to be transported, and then the closing clamping and sealing structure is in close contact with and sealed with the plate-shaped material, so that the lower plate-shaped material blocks the opening of the shell, realizing the sealed state of the inside of the shell, and then the air in the inside of the shell is pumped out by the vacuum pump and the vacuum pipe, so that the inside of the shell is in a negative pressure state, and since the part of the plate-shaped material directly contacting the closing clamping and sealing structure is flexible and can move a small distance upward or downward relative to the shell, based on the movable characteristics of the plate-shaped material relative to the shell, the atmospheric pressure can directly act on the lower plate-shaped material that has been lifted, realizing that the atmospheric pressure provides an upward thrust to the plate-shaped material, thereby reducing the overall weight of the device and the overall weight of the plate-shaped material being lifted, and also avoiding the problem that the flexible sealing strip cannot provide sufficient clamping force when lifting a large number of plate-shaped materials, and if the clamping force is too large, it will damage the edges or side surfaces of the plate-shaped material, of course, when lifting a small number of plate-shaped materials, the sealing strip can provide sufficient clamping force to prevent the plate-shaped material from falling.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0031] As shown in the figure: Figures 1-11

[0032] A plate taking and adjusting device based on dense stacking, comprising a gantry robot, the load end of the gantry robot is fixedly connected with a shell 2 which has an internal space capable of accommodating a plurality of plate-shaped materials 1 and is provided with an open bottom, one end of the shell 2 is fixedly communicated with one end of a vacuum pipe 3, and the other end of the vacuum pipe 3 is communicated with a vacuum pump fixedly;

[0033] The opening size of the bottom of the shell 2 is larger than the size of the plate matched therewith, and the open end of the bottom of the shell 2 is connected with a closing and clamping sealing structure which has the functions of expansion and closing, and when the closing and clamping sealing structure is closed and clamped, a clamping and sealing state can be formed between the closing and clamping sealing structure and the plate-shaped material 1.

[0034] ​​The size of the plate-shaped material 1 on the market is generally 1.2*2.44m, and the conventional thickness is 1.5cm, 1.8cm, 2.0cm, 2.5cm and 3.0cm. The material types are also relatively diverse. Different thicknesses and types of plate-shaped materials 1 are generally placed in the warehouse in a horizontal stacking manner. The bottom of the plate-shaped material 1 is placed on the ground through a wooden tray. The wooden tray can prevent the ground from directly contacting the plate-shaped material 1, causing the plate-shaped material 1 to be damp and have indentations. It is also beneficial to use a forklift to transfer a stack of plate-shaped materials 1. When shipping (shipping means that a customer has ordered and the plate-shaped material 1 is transported out of the warehouse), the forklift is used to transport the entire stack of plate-shaped materials 1 out of the warehouse. In the case of needing a small amount of plate-shaped material 1, manual handling is generally used to transport the plate-shaped material 1 one by one onto the forklift, which is labor-intensive. In addition, when stacking the plate-shaped material 1, space for the forklift to travel needs to be reserved, resulting in low space utilization of the warehouse.

[0035] The present scheme can transport plate-shaped materials 1 without using a forklift. Since the use of a forklift is eliminated, the space utilization of the warehouse can be improved, the warehousing cost can be reduced, and the number of plate-shaped materials 1 needed can be arbitrarily transported without manual handling, avoiding the problem of excessive labor intensity. The housing 2 is moved to directly above the target stacked plate-shaped material 1 by the gantry robot, and then the housing 2 is moved downward by the gantry robot, so that the housing 2 engulfs part of the plate-shaped material 1. The plate-shaped material 1 engulfed by the housing 2 is the number of plate-shaped materials 1 needed to be transported. The sealing structure is in close contact with and sealed with the plate-shaped material 1, so that the plate-shaped material 1 on the lower side blocks the opening of the housing 2, achieving a sealed state inside the housing 2. Then the air inside the housing 2 is pumped out through the vacuum pump and vacuum pipe 3, so that the inside of the housing 2 is in a negative pressure state. Since the part of the plate-shaped material 1 directly in contact with the sealing structure is flexible, it can move a small distance upward or downward relative to the housing 2 to some extent. Based on the movable characteristics of the plate-shaped material 1 relative to the housing 2, the atmospheric pressure outside can directly act on the lower plate-shaped material 1 that has been lifted, achieving an upward thrust of the atmospheric pressure on the plate-shaped material 1, thereby reducing the overall weight of the device and the plate-shaped material 1 being lifted. At the same time, it can also avoid the problem that the flexible sealing strip 5 cannot provide enough clamping force when lifting a large number of plate-shaped materials 1. If the clamping force is too large, it will damage the corners or side surfaces of the plate-shaped material 1. Of course, when the number of plate-shaped materials 1 being lifted is small, the sealing strip 5 can provide enough clamping force to prevent the plate-shaped material 1 from falling.

[0036] From a theoretical and practical operation perspective, the upward lifting force of the atmospheric pressure can be controlled by controlling the degree of vacuum inside the housing 2, so that it is exactly equal to the weight of the plate-shaped material 1, achieving that the plate-shaped material 1 does not bring additional weight pressure to the device when lifting the plate-shaped material 1. The following is a specific analysis:

[0037] The upward lifting force of the atmosphere on the plate material 1 is F = ΔpS, where Δp is the air pressure difference between the inside and outside of the shell 2, and S is the area of ​​the lower surface of the plate material 1 in contact with the atmosphere and perpendicular to the pressure direction. The weight of the plate material 1 is G = mg. To make F = G, i.e., pS = mg, we only need to control the air pressure difference Δp to satisfy the equation. During the vacuuming process, as the gas is continuously extracted, the air pressure inside the shell 2 gradually decreases, and the air pressure outside the shell 2 is atmospheric pressure p_outside. Therefore, by adjusting the amount of gas extracted, we can change the value of p_inside and thus precisely control Δp to achieve pS = mg. In other words, no matter how many plates of material 1 there are, we only need to adjust the air pressure difference between the inside and outside of the shell 2 according to the weight of the plate material 1 to make the upward lifting force of the atmosphere on the plate material 1 equal to the weight of the plate material 1.

[0038] The force of atmospheric pressure acting on an area of ​​1.2m × 2.44m is calculated as S = 1.2m × 2.44m = 2.928m². The pressure calculation formula is F = 101325N / m² × 2.928m² ≈ 296679N. Converting this to tons of force (tons / force), it is approximately 30.25 tons. For example, using several types of wood with different densities and a thickness of 2.5cm (all units are tons / cubic meter), the density of pine and fir is approximately 0.4-0.6 t / m³; the density of poplar and birch is approximately 0.6-0.8 t / m³; and the density of oak... The density of ash wood is approximately 0.8-1.0 t / m³, while the density of engineered wood products (such as MDF) is approximately 0.6-0.9 t / m³. Assuming a total mass of 30 tons, the quantities of different types of boards are as follows: 820 sheets of pine and fir, 586 sheets of poplar and birch, 455 sheets of oak and ash, and 512 sheets of engineered wood. Taking the heaviest quantity of oak and ash as an example, with each sheet being 2.5 cm thick, the total of 455 sheets would stack to a height of 11.3 meters, far exceeding the current safe stacking height and fully meeting existing needs.

[0039] In an optional embodiment, the closing clamping sealing structure includes a rubber side plate 4 and a sealing strip 5, with the top of the rubber side plate 4 fixedly sealed relative to the bottom of the housing 2, and the bottom of the rubber side plate 4 fixedly connected to the sealing strip 5.

[0040] In this embodiment, the main function of the sealing strip 5 is to seal the side surface of the plate-shaped material 1 and apply a clamping force to the plate-shaped material 1. When the closing clamping sealing structure needs to be unfolded, it is convenient for the shell 2 to cover and engulf the plate-shaped material 1. When the closing clamping sealing structure is tightened, it can clamp the bottommost plate-shaped material 1 that is engulfed, thus achieving the function of sealing and clamping. This requires the sealing strip 5 to have the function of movement. When the sealing strips 5 are close to each other, they can form a good sealing effect. When the sealing strips 5 are separated from each other, they can drive the bottom of the rubber side plate 4 fixed to them to move together. The two adjacent rubber side plates 4 are separated in a V-shape. When the sealing strips 5 are close to each other, the two adjacent rubber side plates 4 contact each other and close to form a seal. The rubber side plates 4 need to be made of flexible material with a certain hardness to prevent the rubber side plates 4 from flipping into the shell 2 under the action of vacuum negative pressure.

[0041] In an optional embodiment, the junction of two adjacent rubber side plates 4 is in a herringbone shape with the tips pointing outwards.

[0042] In this embodiment, to prevent the rubber side plate 4 from flipping into the housing 2 under vacuum negative pressure, the joint of two adjacent rubber side plates 4 is arranged in a V-shape with the pointed ends facing outwards. The redundant V-shape structure can further resist the force of external atmospheric pressure. When external atmospheric pressure acts on the joint of the two rubber side plates 4, the air pressure will cause the two rubber side plates 4 to squeeze each other more tightly, improving the sealing effect. The redundant V-shape structure makes it even more difficult for the rubber side plate 4 to flip into the housing 2, given that the rubber side plate 4 has a certain degree of hardness. At the same time, the height of the rubber side plate 4 is low, and both the upper and lower ends are fixed, so the force of atmospheric pressure acting on the rubber side plate 4 is limited.

[0043] In an optional embodiment, the length of the sealing strip 5 is greater than the length of the side of the corresponding plate-shaped material 1.

[0044] In this embodiment, the four sealing strips 5 can be separated from each other. When the sealing strips 5 are connected, there needs to be a certain compressive force at the joint of two adjacent sealing strips 5. Moreover, the sealing strips 5 are flexible and can be deformed after compression. Therefore, the length of the sealing strip 5 is greater than the length of the side of the corresponding plate material 1, which is conducive to mutual compression and avoids air leakage at the joint.

[0045] In an optional embodiment, the internal space of the housing 2 is larger than the plate and larger than or equal to the bottom opening size of the housing 2.

[0046] In this embodiment, since a certain amount of plate material 1 is stored inside the shell 2, if the plate material 1 is exactly the same size as the inside of the shell 2, firstly, the plate material 1 will not be easy to directly enter the inside of the shell 2, and secondly, the plate material 1 will form a seal with the shell 2, so the lowermost plate material 1 of the plate material 1 that is carried and moved by the shell 2 cannot be lifted by the external atmospheric pressure. Therefore, the internal space of the shell 2 needs to be set to be larger than the plate material and larger than or equal to the bottom opening size of the shell 2.

[0047] In an optional embodiment, a rigid frame 6 is fixedly connected to the top of the rubber side plate 4, the top of the rigid frame 6 is fixedly connected to the bottom of the housing 2, and the four corners of the rigid frame 6 are arranged in a V-shape.

[0048] In this embodiment, the four corners of the rigid frame 6 are arranged in a herringbone shape, which corresponds to the herringbone arrangement at the joint of the adjacent rubber side plate 4, thus better maintaining the herringbone arrangement at the joint of the rubber side plate 4.

[0049] In an optional embodiment, a push plate 7 is fixedly connected to one end of the sealing strip 5, a limit block 8 is fixedly connected to the outer side of the push plate 7, the outer surface of the limit block 8 and one side surface of the push plate 7 are slidably connected to the inner side of the end of the retaining bracket 9, a power telescopic rod 10 is fixedly connected to the center of the retaining bracket 9, the end of the telescopic main shaft of the power telescopic rod 10 is fixedly connected to one end of the push plate 7, and the retaining bracket 9 is fixedly connected to the surface of the housing 2 through the connecting bracket 11.

[0050] In this embodiment, the sealing strip 5 needs to clamp, fix and seal the bottommost plate-shaped material 1 being transported. The sealing strip 5 needs to be able to move actively laterally. The connecting bracket 11 is set to fix the retaining bracket 9 relative to the housing 2. The push plate 7 and the limiting block 8 are slidably connected to the ends of the retaining bracket 9 on both sides, which can realize the stable lateral movement of the push plate 7 relative to the retaining bracket 9. The power telescopic rod 10 can be a hydraulic rod or an electric screw, which can provide linear thrust or pull. The power telescopic rod 10 can drive the push plate 7 to move horizontally, thereby causing the push plate 7 to drive the sealing strip 5 to move.

[0051] In an optional embodiment, a plurality of inclined plates 12 are fixedly connected to the bottom inner side of the housing 2, and the inclined edge of the inclined plate 12 is connected to the bottom inner edge of the housing 2.

[0052] In this embodiment, as Figure 3 and Figure 4 As shown, the inclined plate 12 not only increases the structural strength of the bottom of the shell 2, but also allows the plate material 1 inside the shell 2 to slide down the inclined plate 12 when unloading, thus preventing the plate material 1 from getting stuck inside the shell 2 and not being easy to get off.

[0053] In an optional embodiment, a hanger 13 is fixedly connected to the top of the housing 2, a heavy-duty tension sensor 14 is fixedly connected to the top of the hanger 13, and a lug 15 is fixedly connected to the top of the heavy-duty tension sensor 14.

[0054] In this embodiment, as in the above embodiment, different negative pressures are required depending on the weight of the plate material 1. In fact, regardless of the negative pressure inside the shell 2 or the weight of the plate material 1, when the tensile force detected by the heavy-duty tensile sensor 14 is only the weight of the device itself, it means that when the atmospheric pressure generated by the negative pressure acts on the plate material 1, it exactly offsets the weight of the plate material 1, thus achieving the final goal.

[0055] In an optional embodiment, the portion of the closing clamping sealing structure that is in direct contact with the plate material 1 is not less than the thickness of three plates of material 1.

[0056] In this embodiment, the part of the sealing structure that directly contacts the plate material 1 is the thickness of the sealing strip 5. Assuming there are many types of plate materials 1, the thickness of the sealing strip 5 is not less than the thickness of the three thickest plate materials 1. Thus, regardless of whether the sealing strip 5 is clamped between two plate materials 1, the sealing strip 5 will inevitably form a seal with one plate material 1. The external atmospheric pressure acts directly on the plate material 1 that forms the seal. At this time, there may be another plate material 1 below the plate material 1 that forms the seal. Since the weight of a single plate material 1 is relatively light, the bottommost plate material 1 can be directly clamped and fixed by the sealing strip 5.

[0057] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
