Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a stacking device. Background Technology

[0002] Tinplate, also known as tinplate, is widely used in food packaging, chemical containers, electronic components and other fields due to its excellent corrosion resistance and beautiful appearance.

[0003] In traditional production environments, the stacking and handling of tinplate typically relies on manual labor. However, due to the heavy weight of tinplate, manual stacking not only requires significant manpower but also leads to excessive labor intensity for workers, increasing fatigue and potential safety hazards. Furthermore, the sheet-like structure of tinplate makes it difficult for workers to handle by hand, increasing the risk of slipping or tilting during handling, further complicating the operation and increasing its danger. Utility Model Content

[0004] In view of the above-mentioned existing situation, this application provides a stacking device that can solve the problem of low automation in the handling of tin-plated steel sheets.

[0005] This utility model provides a stacking device, comprising: a frame; a ventilator connected to the frame, wherein the ventilator has a plurality of airflow grooves on its lower side, the airflow grooves communicating with the outside, and the ventilator also having an air passage communicating with the airflow grooves; an air extraction assembly connected to the frame, the air extraction assembly communicating with the air passage and used to extract external air to increase the airflow velocity in the airflow grooves; and a conveying assembly connected to the frame, wherein the conveying assembly is located on one side of the ventilator and is used to convey workpieces toward the ventilator, and the workpieces are conveyed to the area below the ventilator.

[0006] Optionally, the venting component includes opposing airflow surfaces and connecting surfaces, and the airflow groove is recessed from the direction of the airflow surface toward the connecting surface; in planar projection, the airflow groove has an annular structure, and multiple airflow grooves are distributed in a concentric circle.

[0007] Optionally, the plurality of airflow channels include a first airflow channel and a second airflow channel, with the first airflow channel surrounding the second airflow channel; the ventilation channel includes a main ventilation channel and a plurality of secondary ventilation channels; the secondary ventilation channels connect the first airflow channel and the second airflow channel, and the main ventilation channel connects the secondary ventilation channels and the air extraction assembly respectively.

[0008] Optionally, the stacking device includes a stacking area located below the vent; the stacking device also includes guides; the guides are provided on both sides of the stacking area in a direction perpendicular to the conveying direction of the conveying assembly, and the guides are used to guide the stacking of workpieces.

[0009] Optionally, the guide includes a first inclined surface and a vertical surface connected to each other; the vertical surface is located below the first inclined surface and is perpendicular to the horizontal plane; the first inclined surface is inclined upwards in a direction away from the stacking area.

[0010] Optionally, the guide further includes a second inclined surface connected to one end of the vertical surface opposite to the first inclined surface; the second inclined surface is inclined downwards in a direction opposite to the stacking area.

[0011] Optionally, the stacking device further includes a mounting frame; the stacking device includes a plurality of the ventilation elements, which are mounted on the mounting frame and spaced apart.

[0012] Optionally, the stacking device further includes a plurality of mounting frames; the plurality of mounting frames are spaced apart and parallel to each other.

[0013] Optionally, the exhaust assembly includes an exhaust fan and a vent pipe; the exhaust fan is mounted on the frame, and the vent pipe is connected to both the vent and the exhaust fan.

[0014] Optionally, the conveying assembly includes a conveying drive and multiple conveyor belts; the multiple conveyor belts are spaced apart and arranged in parallel.

[0015] The stacking device of this utility model includes a frame, a venting component, an air extraction component, and a conveying component. The venting component has multiple airflow channels on its lower side, which communicate with the outside. The venting component also has air passages communicating with the airflow channels. The air extraction component is connected to the air passages and is used to extract external air to increase the airflow velocity within and around the airflow channels. The conveying component is used to convey workpieces towards the venting component, and the workpieces are conveyed to a position below the venting component. Therefore, the stacking device of this utility model can increase the airflow velocity within and around the airflow channels of the venting component. According to the Numberley effect, "the greater the velocity, the lower the pressure," when the workpiece is conveyed to a position below the venting component, the airflow velocity within and around the airflow channels of the venting component is high, resulting in an pressure imbalance on both sides of the workpiece, with the pressure above the workpiece being less than the pressure below. Thus, the workpiece can be suspended before stacking. When the air extraction component stops extracting air, the pressure on both sides of the workpiece tends to balance again, and the workpiece falls under the influence of gravity, completing the stacking process. Therefore, the stacking device of this invention can effectively reduce the labor intensity of manual stacking, has a high degree of automation, and improve stacking efficiency. Furthermore, during the stacking process, the ventilation components do not come into contact with the workpiece, thus reducing the risk of damage. Attached Figure Description

[0026] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0027] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0028] Reference Figures 1 to 4 This application provides a stacking device, which includes a frame (not shown in the figure), a ventilation component 1, an air extraction component 2, and a conveying component 3. The ventilation component 1 is connected to the frame, and a plurality of air flow channels 11 are provided on the lower side of the ventilation component 1. The air flow channels 11 communicate with the outside. The ventilation component 1 is also provided with an air passage communicating with the air flow channels 11. The air extraction component 2 is connected to the frame, and the air extraction component 2 communicates with the air passage and is used to extract external air to increase the air flow velocity in and around the air flow channels 11. The conveying component 3 is connected to the frame and is located on one side of the ventilation component 1. The conveying component 3 is used to convey the workpiece 100 toward the ventilation component 1, and the workpiece 100 is conveyed to the lower part of the ventilation component 1.

[0029] Based on the above structure, the stacking device involved in this application can increase the air velocity within and around the airflow channel 11 of the ventilation component 1. According to the Numberley effect principle that "the greater the velocity, the lower the pressure," the air velocity within and around the airflow channel 11 of the ventilation component 1 is relatively high. At this time, the area below the ventilation component 1 can be considered as forming a rapidly flowing air film. When the workpiece 100 is conveyed to the area below the ventilation component 1, the pressure on both sides of the workpiece 100 is unbalanced, with the pressure above the workpiece 100 being less than the pressure below it. The air pressure below provides a certain supporting effect on the workpiece 100, allowing it to remain suspended. When the air extraction component 2 stops extracting air, the pressure on both sides of the workpiece 100 tends to balance again, and the workpiece 100 falls under the influence of gravity, completing the stacking process. Therefore, the stacking device in this application can effectively reduce the labor intensity of manual stacking, has a high degree of automation, and improve stacking efficiency. In addition, during the stacking process, the ventilation component 1 does not need to come into contact with the workpiece 100, thus preventing damage to the workpiece 100.

[0030] Reference Figure 1 In some embodiments, the exhaust assembly 2 may include an exhaust fan 21 and a vent pipe 22; the exhaust fan 21 is mounted on the frame, and the vent pipe 22 is connected to the ventilation channel and the exhaust fan 21 respectively. When the exhaust fan 21 is activated, it can extract air from the airflow channel 11 and its surroundings, thereby increasing the airflow velocity in and around the airflow channel 11 of the ventilation component 1. The exhaust process can also play a certain role in adsorption, improving the suspension effect of the workpiece 100. After the exhaust fan 21 stops working, the workpiece 100 falls and the stacking is completed. Specifically, the suction force can be controlled by adjusting the rotation speed of the exhaust fan 21 so that the adsorption of the workpiece 100 by the exhaust assembly 2 is controlled within a suitable force. Thus, the workpiece 100 can be suspended below the ventilation component 1 without sticking to it.

[0031] Reference Figure 1 It is understandable that when stacking tinplate, if there is no ventilation component 1 and the exhaust component 2, the tinplate will fall in a tilted state after being conveyed out by the conveying component 3. That is, the front end of the tinplate will fall down first. As a result, the front end of the tinplate is very easy to be bumped and damaged.

[0032] Using the stacking device of this application, the conveying component 3 conveys the tin-plated steel sheet towards the ventilation component 1. During the conveying process, the front end of the tin-plated steel sheet will first detach from the conveying component 3, and the part of the tin-plated steel sheet that detaches from the conveying component 3 will be located below the ventilation component 1. The exhaust component 2 operates, and the exhaust component 2 can extract external air through the ventilation channel. According to the Numberley effect principle that "the greater the velocity, the lower the pressure", the air velocity in and around the airflow channel 11 of the ventilation component 1 is relatively high. When the tin-plated steel sheet is conveyed to the area below the ventilation component 1, the pressure on both sides of the tin-plated steel sheet is unbalanced, and the pressure above the tin-plated steel sheet is less than the pressure below the tin-plated steel sheet. Therefore, the tin-plated steel sheet can be in a suspended state before stacking. At this time, the ventilation component 1 and the exhaust component 2 work together to keep the tin-plated steel sheet in a straight state and prevent it from tilting. When the exhaust component 2 stops extracting air, the tin-plated steel sheet can fall straight down, thereby completing the stacking.

[0033] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the vent 1 includes opposing airflow surfaces and connecting surfaces, with airflow grooves 11 recessed from the airflow surfaces toward the connecting surfaces. In planar projection, the airflow grooves 11 have an annular structure, and multiple airflow grooves 11 are distributed concentrically. Thus, the airflow grooves 11 can be evenly distributed on the side of the vent 1, and the multiple concentrically distributed airflow grooves 11 can effectively participate in guiding and distributing airflow, avoiding excessive airflow concentration and pressure buildup.

[0034] Reference Figure 5 The system includes multiple airflow channels 11, including a first airflow channel 111 and a second airflow channel 112, with the first airflow channel 111 surrounding the second airflow channel 112. The ventilation duct includes a main ventilation duct 12 and multiple auxiliary ventilation ducts 13. The auxiliary ventilation ducts 13 connect the first airflow channel 111 and the second airflow channel 112, and the main ventilation duct 12 connects to both the auxiliary ventilation ducts 13 and the extraction assembly 2. Therefore, the main ventilation duct 12 and the multiple auxiliary ventilation ducts 13 can achieve more efficient airflow guidance. The auxiliary ventilation ducts 13 connect the first airflow channel 111 and the second airflow channel 112, ensuring smooth airflow between different airflow channels 11, thereby achieving a more uniform airflow distribution and improving ventilation efficiency. The main ventilation duct 12 is the core channel of the entire airflow system. It not only connects to multiple secondary ventilation ducts 13, but also directly connects to the extraction assembly 2, ensuring that the airflow can be gathered from the airflow slot 11 through the secondary ventilation ducts 13 to the main ventilation duct 12, thus optimizing the overall airflow path and improving operational stability.

[0035] Reference Figure 6In some embodiments, the stacking device includes a stacking area located below the vent 1; the stacking device also includes guides 4; guides 4 are provided on both sides of the stacking area in a direction perpendicular to the conveying direction of the conveying assembly 3, and the guides 4 are used to guide the workpiece 100 to be stacked. Thus, the guides 4 located on both sides can ensure that the workpiece 100 can be accurately guided into the stacking area when entering the stacking area, avoiding the workpiece 100 from shifting its position during stacking.

[0036] Reference Figure 7 In some embodiments, the guide 4 includes a first inclined surface 41 and a vertical surface 42 connected to each other; the vertical surface 42 is located below the first inclined surface 41 and is perpendicular to the horizontal plane; the first inclined surface 41 is inclined upwards in a direction away from the stacking area. Thus, the arrangement of the first inclined surface 41 helps to provide a smooth transition when the workpiece 100 enters the stacking area, ensuring that the workpiece 100 can be gently guided to the correct position upon contact with the guide 4. Secondly, the vertical surface 42, located below the first inclined surface 41 and perpendicular to the horizontal plane, further positions the workpiece 100 as it passes through the vertical surface 42, thereby guiding the workpiece 100 to fall accurately into the stacking area.

[0037] Reference Figure 7 In some embodiments, the guide 4 further includes a second ramp 43 connected to one end of the vertical surface 42 opposite to the first ramp 41; the second ramp 43 slopes downwards and away from the stacking area. Thus, the second ramp 43 also helps to provide a smooth transition when the workpiece 100 enters the stacking area, ensuring that the workpiece 100 is gently guided to the correct position upon contact with the guide 4, thus better completing the stacking process.

[0038] Reference Figure 2 In some embodiments, the stacking device further includes a mounting frame 5; the stacking device includes a plurality of ventilation elements 1, which are mounted on the mounting frame 5 and spaced apart. Thus, a suitable number of ventilation elements 1 can be provided according to the size of the workpiece 100.

[0039] In some embodiments, the stacking device further includes a plurality of mounting frames 5; the plurality of mounting frames 5 are spaced apart and parallel to each other. Thus, a suitable number of mounting frames 5 can be provided according to the size of the workpiece 100.

[0040] Reference Figure 2 and Figure 3In some examples, each mounting bracket 5 may have 6 vents 1, and the stacking device may have four mounting brackets 5. When stacking tinplate, a rapidly flowing air film with sufficient area can be formed below the mounting bracket 5 or the vents 1, so that the air film can cover the tinplate as much as possible, thereby allowing the air pressure below to better support the tinplate, keeping the tinplate in a flat state and thus stacking it better.

[0041] Reference Figure 2 In some embodiments, the conveying assembly 3 includes a conveying drive and a plurality of conveyor belts 31; the plurality of conveyor belts 31 are spaced apart and arranged in parallel. Thus, the spaced apart and parallel arrangement of the plurality of conveyor belts 31 allows the conveying assembly 3 to form a larger conveying surface, thereby enabling the placement of a larger workpiece 100. The conveying assembly 3 can be configured with reference to structures in related technologies. For example, the conveying drive may include a motor, a drive roller, and a driven roller. The drive roller and the driven roller tension the conveyor belts 31, and the motor is connected to the drive roller to drive the conveyor belts 31 to move and convey the workpiece 100.
