[0054] Compared with the prior art, the present invention has the following advantages:

[0055] This utility model provides a cardboard feeding production line, including a mounting bracket, a second cardboard conveying mechanism for carrying and conveying horizontally placed cardboard, a cardboard picking mechanism mounted on the mounting bracket and located above the second cardboard conveying mechanism, and a cardboard conveying device for receiving cardboard and keeping it vertically placed for conveying to the next station. During production, the second cardboard conveying mechanism conveys the horizontally stacked cardboard after destacking. The cardboard picking mechanism picks up the horizontally placed cardboard from the second cardboard conveying mechanism, flips the cardboard to a vertical position, and then transfers it to the cardboard conveying device. The cardboard conveying device receives the cardboard and keeps it vertically placed for conveying to the next station, realizing automatic cardboard picking and transfer. The horizontally placed cardboard is placed vertically on the conveying device of the next station, and the cardboard is kept vertically placed for conveying. No manual placement is required, saving time and labor and improving production efficiency.

[0056] Meanwhile, to prevent cardboard from shifting or misaligning when placed vertically on the conveying device, thus affecting subsequent production and processing, the cardboard conveying device of this application includes a first cardboard conveying mechanism for carrying and conveying cardboard within a mounting bracket, a first baffle assembly on one side of the first cardboard conveying mechanism, and a first cardboard correction mechanism and a second cardboard correction mechanism on the mounting bracket. In use, the cardboard picking mechanism places the cardboard vertically on the first cardboard conveying mechanism. The second cardboard correction mechanism supports the cardboard to prevent it from tipping over and pushes one end face of the cardboard so that the end faces of adjacent cardboards are pressed together and stacked. Then, the first cardboard correction mechanism and the first baffle assembly work together to correct the two sides of the cardboard, making the two sides of the cardboard flush. This not only enables the conveying of vertically placed cardboard but also prevents some cardboard from shifting or protruding on the side, facilitating subsequent production and processing.

[0057] Furthermore, when the paperboard picking mechanism picks up paperboard from the second paperboard conveying mechanism, it does not need to lift the paperboard on the second paperboard conveying mechanism through a lifting mechanism. The second paperboard conveying mechanism of this application includes two oppositely arranged conveying mounting side plates, a conveying roller rotatably disposed between the two conveying mounting side plates, and a conveying drive assembly for driving the conveying roller to rotate. The upper end of the conveying mounting side plates is provided with a clearance notch.

In use, the picking drive assembly can drive one clamping member to move and extend into the clearance notch so that the upper end surface of the clamping member is not higher than the upper end surface of the conveying roller. Without the need to use a lifting mechanism to lift the paperboard, the paperboard on the conveying line can be directly clamped and picked up. The structure is simpler, the production efficiency is higher, and the cost is lower. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0070] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of this utility model, unless they actually express the meaning of order according to the context, they should be understood as being used only for differentiation.

[0071] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0072] Specific embodiments, such as Figure 1-10The illustrated cardboard feeding production line includes: a mounting bracket 11; a second cardboard conveying mechanism 21 for carrying and conveying horizontally placed cardboard; a cardboard picking mechanism 23, mounted on the mounting bracket 11 and located above the second cardboard conveying mechanism 21, for gripping the horizontally placed cardboard on the second cardboard conveying mechanism 21, flipping the cardboard to a vertical position, and then transferring it to the next workstation; and a cardboard conveying device 1 for receiving the cardboard transferred by the cardboard picking mechanism 23 and keeping the cardboard vertically placed before conveying it to the next workstation. During production, the second cardboard conveying mechanism conveys the horizontally stacked cardboard after destacking. The cardboard picking mechanism grips the horizontally placed cardboard on the second cardboard conveying mechanism, flips the cardboard to a vertical position, and then transfers it to the cardboard conveying device. The cardboard conveying device receives the cardboard and keeps it vertically placed before conveying it to the next workstation. This achieves automatic gripping and transfer of cardboard, vertically placing the horizontally placed cardboard on the conveying device at the next workstation, and maintaining the vertical position of the cardboard during conveying. No manual placement is required, saving time and labor, and improving production efficiency.

[0073] Specifically, the second cardboard conveying mechanism 21 includes two oppositely arranged conveying mounting side plates 211, a conveying roller 212 rotatably disposed between the two conveying mounting side plates 211, and a conveying drive assembly 213 for driving the conveying roller 212 to rotate. The upper end of each conveying mounting side plate 211 is provided with a clearance notch 22. The cardboard picking mechanism 23 includes two oppositely arranged clamping members 231, and a picking drive assembly 232 for driving the two clamping members 231 to clamp and move. The picking drive assembly 232 can drive one of the clamping members 231 to move and extend into the clearance notch 22, so that the upper end surface of the clamping member 231 is not higher than the upper end surface of the conveying roller 212. In use, the picking drive assembly can drive a clamping member to move and extend into the clearance notch, so that the upper end surface of the clamping member is not higher than the upper end surface of the conveying roller. Without the need for a lifting mechanism to lift the cardboard, the cardboard on the conveyor line can be directly clamped and picked up, resulting in a simpler structure, higher production efficiency, and lower cost.

[0074] Specifically, the conveying drive assembly 213 includes: a drive conveying motor 2131, mounted on the conveying mounting side plate 211; a first transmission wheel 2132, located at the rotational output end of the drive conveying motor 2131; a second transmission wheel 2133, located at one end of the conveying roller 212 near the first transmission wheel 2132; and a transmission chain (not shown in the figure), located on the first transmission wheel 2132 and the second transmission wheel 2133, for connecting the first transmission wheel 2132 and the second transmission wheel 2133. By driving the first transmission wheel 2132 to rotate through the drive conveying motor 2131, and by driving each conveying roller 212 to rotate through the transmission chain and the second transmission wheel 2133, automated paperboard feeding is achieved.

[0075] Additionally, the material handling drive assembly 232 includes: a clamping drive mounting member 2321, which has two opposing first mounting cavities 24; a clamping slide rail 2322, which passes through the inner walls of the two first mounting cavities 24; clamping sliders 2323, which are movably mounted on the clamping slide rail 2322, and the two clamping members 231 are respectively mounted on the two clamping sliders 2323; and a clamping drive member 2324, which is mounted on the clamping drive mounting member 2321 and is used to drive the two clamping sliders 2323 to move towards each other or away from each other on the clamping slide rail 2322. The clamping sliders 2323 move within the clamping slide rail 2322 in the first mounting cavity 24, making reasonable use of the space of the clamping drive mounting member 2321 and reducing the overall footprint. While existing robotic arms have a large working space for swinging when performing material picking and placing actions, the material picking drive component of this application occupies less space and has a lower cost compared to existing robotic arms for material picking.

[0076] Furthermore, the clamping slider 2323 is provided with a second mounting cavity 25, the first mounting cavity 24 and the second mounting cavity 25 are connected, and the clamping drive member 2324 is disposed between the first mounting cavity 24 and the second mounting cavity 25. The clamping drive member 2324 is a telescopic cylinder, one end of which is located in the first mounting cavity 24 and connected to the clamping drive mounting member 2321, and the telescopic end extends into the second mounting cavity 25 and is connected to the clamping slider 2323, resulting in a more compact structure and a smaller footprint.

[0077] More specifically, one end of the clamping member 231 is connected to the clamping sliding member 2323, and the other end extends out of the first mounting cavity 24. The clamping drive mounting member 2321 is provided with a clearance groove 26 for the clamping member 231 to move through. The clamping member 231 can extend into the clearance groove 26, making the appearance more beautiful, the structure more compact, and the overall footprint smaller.

[0078] Furthermore, the material picking drive assembly 232 further includes: a material picking drive mounting member 2325, which has a third mounting cavity 27 therein; a material picking flipping drive structure 2326, which is disposed on the material picking drive mounting member 2325 and is used to drive the clamping drive mounting member 2321 to rotate; a Z-axis drive structure 2327, which is disposed on the material picking drive mounting member 2325 and is used to drive the material picking flipping drive structure 2326 to move up and down along the Z-axis direction; an X-axis drive structure 2328, which is used to drive the material picking drive mounting member 2325 to move horizontally along the X-axis direction; and a Y-axis drive structure 2329, which is disposed on the mounting bracket 11 and is used to drive the X-axis drive structure 2328 to move horizontally along the Y-axis direction. In use, the clamping member 231 is driven to translate along the X-axis and Y-axis and Z-axis directions by the X-axis drive structure 2328 and the Y-axis drive structure 2329 respectively, and the clamping member 231 is driven to flip by the material picking and flipping drive structure 2326 so that the clamping member 231 is aligned with the clearance notch 22. Then, the clamping member 231 is driven to move and extend into the clearance notch 22 by the Z-axis drive structure 2327. The structure is compact and the working range of the clamping member 231 is small, that is, the overall space occupied during operation is small.

[0079] Furthermore, the material handling and flipping drive structure 2326 includes: a flipping mounting base 2326a, which is movably mounted on the material handling drive mounting member 2325 along the Z-axis direction and located in the third mounting cavity 27; a flipping drive shaft 2326b, one end of which is connected to the clamping drive mounting member 2321, and the other end of which rotatably passes through the flipping mounting base 2326a; a swing drive member 2326c, one end of which is connected to the end of the flipping drive shaft 2326b away from the clamping drive mounting member 2321; and a swing drive telescopic cylinder 2326d, which is mounted on the flipping mounting base 2326a, and the telescopic end of which is connected to the end of the swing drive member 2326c away from the flipping drive shaft 2326b. In use, the telescopic end of the swing-driven telescopic cylinder 2326d pushes the swing drive component 2326c to swing, which in turn drives the flip drive shaft 2326b to rotate, thereby flipping the clamping component 231 45°. This flips the horizontal cardboard on the clamping component 45° to a vertical position, which is then driven by the material picking drive assembly 232 to move it to another conveyor line, thus realizing the cardboard flipping and feeding. Using the swing-driven telescopic cylinder 2326d instead of the servo motor results in lower costs.

[0080] Specifically, the Z-axis drive structure 2327 includes: a Z-axis drive guide rail 2327a, which is disposed on the material picking drive mounting component 2325 along the Z-axis direction and located in the third mounting cavity 27; the flip mounting seat 2326a is movably disposed on the Z-axis drive guide rail 2327a; a Z-axis drive screw sleeve (not shown in the figure), which is disposed on the flip mounting seat 2326a; a Z-axis drive lead screw 2327c, which is rotatably disposed on the material picking drive mounting component 2325; the Z-axis drive screw sleeve is sleeved on the Z-axis drive lead screw 2327c; and the two Z-axis drive screw sleeves are respectively disposed on both sides of the flip mounting seat 2326a. The lifting and lowering movement of the flip mounting seat 2326a is achieved by the cooperation of the lead screw and the screw sleeve, which is a conventional design method for those skilled in the art and will not be described in detail here; and a Z-axis drive motor 2327d, which is disposed on the material picking drive mounting component 2325 and is used to drive the Z-axis drive lead screw 2327c to rotate. A transmission rod 2327b is connected to a Z-axis drive motor 2327d, and the transmission rod 2327b drives the Z-axis drive screw 2327c to rotate through a transmission gear. This enables stable lifting and lowering of the clamping component 231, and allows the flip mounting base 2326a to lift and lower within the third mounting cavity 27. The structure is compact, the overall size is small, and it occupies less space.

[0081] Optionally, the X-axis drive structure 2328 of this application may employ a guide rail arranged along the X-axis direction, a wheel mounted on the guide rail, a conveyor belt sleeved on the wheel, and a motor driving the wheel to rotate. The material handling drive mounting component 2325 is connected to the conveyor belt and moves flexibly with the conveyor belt. Similarly, the Y-axis drive structure 2329 may employ a guide rail arranged along the Y-axis direction, a wheel mounted on the guide rail, a conveyor belt sleeved on the wheel, and a motor driving the wheel to rotate. The X-axis drive structure 2328 is connected to the conveyor belt and moves flexibly with the conveyor belt.

[0082] Further, the cardboard conveying device includes: a first cardboard conveying mechanism 12, which is disposed within the mounting bracket 11 and is used to carry and convey cardboard; a first baffle assembly 13, which is disposed on one side of the first cardboard conveying mechanism 12; a first cardboard correction mechanism 14, which is disposed on the mounting bracket 11 and is used to cooperate with the first baffle assembly 13 to correct the cardboard on the first cardboard conveying mechanism 12 so that the two sides of the cardboard are flush; and a second cardboard correction mechanism 15, which is disposed on the mounting bracket 11 and is used to support and push one end face of the cardboard on the first cardboard conveying mechanism 12 so that the end faces of adjacent cardboards are in contact. Optionally, the first cardboard conveying mechanism 12 is a conveyor belt. In use, the cardboard feeding mechanism places the cardboard vertically on the first cardboard conveying mechanism. The second cardboard correction mechanism supports the cardboard to prevent it from tipping over and pushes one end of the cardboard so that the ends of adjacent cardboards are pressed together and stacked. Then, the first cardboard correction mechanism works with the first baffle assembly to correct the deviation of both sides of the cardboard, making the two sides of the cardboard flush. This not only enables the conveying of vertically placed cardboard, but also prevents some cardboard from shifting or protruding on the side, facilitating subsequent production and processing.

[0083] Specifically, the first paperboard correction mechanism 14 includes a first correction roller 141 arranged along the paperboard conveying direction and a first correction drive assembly 142 for driving the first correction roller 141 to move towards the first stop assembly 13. By driving the first correction roller 141 to move towards the first stop assembly 13 through the first correction drive assembly 142, it can cooperate with the first stop assembly 13 to correct the deviation of both sides of the stacked paperboard, making the two sides of the paperboard flush, so that it can be used for subsequent paperboard conveying and production processing.

[0084] More specifically, the first correction drive assembly 142 includes: a correction rotating component 1421, two correction rotating components 1421 rotatably mounted on the mounting bracket 11, and the two ends of the first correction roller 141 are respectively connected to one end of the two correction rotating components 1421; a correction drive component 1422, which is mounted on the mounting bracket 11, for driving the correction rotating component 1421 to rotate, thereby driving the first correction roller 141 to swing downward in an arc shape toward the cardboard, or swing upward in an arc shape away from the cardboard. The upper corner of the cardboard has a notch. During correction, the correction drive component 1422 drives the first correction roller 141 to swing downward in an arc shape toward the cardboard and extend into the notch at the upper corner of the cardboard. That is, the first correction roller 141 exerts force on the cardboard in both the horizontal and vertical directions, realizing the alignment of the upper and lower sides and the left and right sides of the cardboard, which is then used for subsequent cardboard conveying and processing.

[0085] Furthermore, the correction drive component 1422 includes a correction telescopic cylinder, which is mounted on the mounting bracket 11 and its telescopic end is connected to the end of the correction rotating component 1421 away from the first correction roller 141. Using a telescopic cylinder instead of a servo motor to drive the reciprocating oscillation of the correction rotating component 1421 results in high efficiency and low cost.

[0086] More specifically, the second cardboard correction mechanism 15 includes: a push plate mounting component 151, mounted on a mounting bracket 11; a push plate drive telescopic cylinder 152, mounted on the push plate mounting component 151 along the cardboard conveying direction; a push plate component 153, located at the telescopic end of the push plate drive telescopic cylinder 152; a push plate guide sleeve 154, mounted on the push plate mounting component 151; and a push plate guide post 155, one end of which is connected to the push plate component 153, and the other end of which movably passes through the push plate guide sleeve 154. In use, the push plate drive telescopic cylinder 152 drives the push plate component 153 to approach the cardboard, thereby supporting and pushing the cardboard and preventing the cardboard placed vertically on the conveyor line from tipping over. Furthermore, the cooperation between the push plate guide sleeve 154 and the push plate guide post 155 ensures stable movement of the push plate component 153.

[0087] Furthermore, the second paperboard correction mechanism 15 also includes: a second correction roller 156, which is arranged in a direction perpendicular to the paperboard conveying direction, for supporting and pushing one end face of the paperboard on the first paperboard conveying mechanism 12 so that the end faces of adjacent paperboards are in contact; and a correction roller drive structure 157, which is mounted on the mounting bracket 11, for driving the second correction roller 156 to move in the vertical direction and in the paperboard conveying direction. In use, the push plate drive telescopic cylinder 152 drives the push plate component 153 to move backward, and the second correction roller 156 supports the vertically placed cardboard in front to prevent the cardboard from tipping over. Then, the cardboard from the previous station is picked up and placed on the first cardboard conveying mechanism 12 between the second correction roller 156 and the push plate component 153 by means of a robot. At this time, the push plate drive telescopic cylinder 152 pushes the push plate component 153 close to the cardboard to support the cardboard. Then, the correction roller drive structure 157 drives the second correction roller 156 to move vertically upward and then horizontally to the back of the cardboard. Then, it moves vertically downward and together with the push plate component 153 supports the cardboard. By working in this way, the cardboard is vertically placed and conveyed, and the cardboard can be prevented from tipping over.

[0088] Furthermore, the correction roller drive structure 157 includes: correction roller mounting parts 1571, two correction roller mounting parts 1571 are disposed opposite each other on both sides of the mounting bracket 11, and the two ends of the second correction roller 156 are respectively connected to the two correction roller mounting parts 1571; correction roller lifting drive assembly 1572, which is used to drive the correction roller mounting parts 1571 to move in the vertical direction; and correction roller horizontal drive assembly 1573, which is used to drive the correction roller lifting drive assembly 1572 and the correction roller mounting parts 1571 to move in the paperboard conveying direction. The straightening roller lifting drive assembly 1572 can use a telescopic cylinder in conjunction with a slide rail to drive the straightening roller mounting component 1571 to move up and down; the straightening roller horizontal drive assembly 1573 can use a belt conveyor or other means to drive the straightening roller lifting drive assembly 1572 to move horizontally, and is movably mounted on the slide rail via a sliding seat, and is driven to move horizontally via a belt conveyor.
