Description

Technical Field

[0001] This utility model relates to the technical field of product production and transportation systems, and in particular to a material box feeding device and a material box transport line. Background Technology

[0002] Material box feeding devices are key pieces of equipment widely used in automated production. They are used to separate and transport material boxes, such as those in the pharmaceutical industry. With the continuous improvement of industrial automation, higher demands are being placed on the stability, accuracy, and degree of automation of material box feeding devices.

[0003] In the existing technology, there are two main ways to perform material distribution operations on box-shaped materials: one is to use a robotic arm or distribution plate to distribute the horizontally arranged boxes one by one, which is suitable for single-layer, linear material conveying scenarios; the other is to use a material blocking mechanism in conjunction with gravity falling, and control the material to fall one by one through a material clamping structure, which is suitable for vertical material supply.

[0004] In practical applications, in order to improve space utilization and conveying efficiency, it is often necessary to divide the stacked material boxes layer by layer.

[0005] However, when using existing technology to distribute materials layer by layer from stacked boxes, it mainly relies on the weight of the materials themselves to fall, which makes it impossible to control and accurately distribute the materials. This can easily lead to problems such as jamming and misalignment, affecting the efficiency of material distribution and the stable operation of production equipment. Utility Model Content

[0006] The purpose of this invention is to provide a material box feeding device and a material box transport line to alleviate the technical problem in the prior art that it is impossible to control and accurately divide stacked material boxes.

[0007] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: In a first aspect, this utility model provides a material box feeding device, comprising: The hopper assembly has a discharge channel for multiple stacked material boxes to fall into; A material blocking assembly includes a material blocking assembly mounting frame, a rotating mechanism mounted on the material blocking assembly mounting frame, and at least two baffles connected to the rotating mechanism; the baffles extend horizontally, and each pair of baffles is arranged on opposite sides of the material feeding channel in the horizontal direction, with all baffles at the same height; the rotating mechanism drives all the baffles to rotate in the horizontal plane so that the baffles support or release the edge of the bottom or second-bottom material box in the material feeding channel; The material dispensing assembly includes a lifting mechanism and a clamping mechanism; the clamping mechanism is connected to the execution end of the lifting mechanism and clamps or releases the edge of the bottom material box in the material dispensing channel.

[0008] In an optional embodiment, the rotating mechanism includes a power output component and a linkage component; The power output component is mounted on the baffle assembly mounting frame; one end of each baffle is connected to the power output component via a set of linkage components; the power output component drives all the baffles to rotate synchronously in the horizontal plane via the linkage components.

[0009] In an optional implementation, the power output component is a translation drive component; The linkage components include a sliding plate, a connecting rod, and a rotating shaft; The material stop assembly mounting bracket is provided with a slide rail extending horizontally. The slide plate extends horizontally and is slidably mounted on the slide rail. The slide plate is fixedly connected to the actuator end of the translation drive assembly. A cam follower is installed at one end of the slide plate. The connecting rod extends horizontally and has an elongated hole extending along the length of the connecting rod. The sliding limit of the cam follower is located inside the elongated hole on the connecting rod. The rotating shaft extends vertically and is arranged on one side of the material feeding channel in the horizontal direction. The lower end of the rotating shaft is rotatably connected to one end of the connecting rod. One end of the baffle is fixedly connected to the upper end of the rotating shaft. The translation drive assembly drives the slide plate to slide back and forth along the slide rail, causing the connecting rod to swing back and forth in the horizontal plane, so as to cause the rotating shaft to rotate around its own axis, thereby causing the baffle to rotate in the horizontal plane.

[0010] In an optional embodiment, every two linkage components share one slide plate, wherein cam followers are installed at both ends of the slide plate, and the cam followers at both ends are respectively slidably limited inside the elongated hole provided on the connecting rod of one of the linkage components.

[0011] In an optional embodiment, the translation drive assembly is provided in multiple sets, the same number as the number of slide plates, and each translation drive assembly drives each slide plate to slide back and forth along the slide rail.

[0012] In an optional embodiment, the material stop assembly further includes a plurality of guide bushings, each of the rotating shafts passing through the respective guide bushings. The guide bushings are used to be fixedly installed on the operating table and communicate with the shaft holes provided on the operating table for the rotating shafts to pass through, so as to limit the rotation of the rotating shafts.

[0013] In an optional embodiment, the baffle has an intercepting end at one end facing the feeding channel, the thickness of the intercepting end being less than the thickness of the rest of the baffle, and the width of the intercepting end being greater than the width of the rest of the baffle.

[0014] In an optional embodiment, the material distribution assembly has at least two clamping mechanisms, with each pair of clamping mechanisms arranged on opposite sides of the material feeding channel in the horizontal direction.

[0015] In an optional embodiment, the material dispensing assembly further includes a material dispensing assembly mounting bracket; Each of the clamping mechanisms includes a clamping arm, a horizontal telescopic mechanism, and a clamping block; The lower end of the clamping arm is fixedly connected to the material distribution assembly mounting frame; The horizontal telescopic mechanism is installed at the upper end of each of the clamping arms; The clamping block is fixedly connected to the execution end of the horizontal telescopic mechanism, and the clamping block has a clamping groove on the side facing the unloading channel. Furthermore, the clamping grooves of all the clamping blocks are at the same height. The horizontal telescopic mechanism drives the clamping block to extend toward the inside of the feeding channel so that the clamping groove clamps the edge of the material box.

[0016] Secondly, this utility model provides a material box transport line, including an operating table, a horizontal conveyor belt, and a material box feeding device provided in any optional embodiment of the first aspect; The horizontal conveyor belt is mounted above the operating table and located below the unloading channel; The baffle is located above the horizontal conveyor belt, the baffle assembly mounting frame is located below the operating table, and the lifting mechanism is located below the baffle assembly mounting frame.

[0017] The embodiments of this utility model can achieve at least the following beneficial effects: In operation, a material box transport line is provided, which includes an operating table, a horizontal conveyor belt and the aforementioned material box loading device, such that the horizontal conveyor belt is mounted above the operating table and below the unloading channel; the upper ends of the baffle and the clamping mechanism are both located above the horizontal conveyor belt.

[0018] In the initial state, the bottom material box in the feeding channel is supported by the baffle assembly. Specifically, its rotating mechanism drives all the baffles to rotate in the horizontal plane so that one end of each baffle is screwed into the feeding channel to support the edge of the bottom material box. Then, the bottom material box's edge is clamped by the material distribution component. Specifically, its lifting mechanism drives the clamping mechanism to be located outside the bottom material box, and then the clamping mechanism closes to clamp the bottom material box's edge. Next, the material blocking assembly releases the bottom material box, that is, its rotating mechanism drives the baffle to rotate in the horizontal plane so that the baffle rotates out of the feeding channel to release the bottom material box. Next, the material distribution component clamps the bottom material box and lowers it by the stacking height of one material box. The rotating mechanism of the baffle component drives the baffle to rotate in the horizontal plane so that one end of the baffle is screwed back into the material feeding channel to support the edge of the next bottom material box. Next, the material distribution component clamps the bottom material box and lowers it until the bottom material box lands on the horizontal conveyor belt. The clamping mechanism then opens to release the bottom material box. Repeat the above process to feed the stacked material boxes onto the horizontal conveyor belt.

[0019] In the material box feeding device provided in this embodiment of the utility model, the baffle assembly dynamically supports and releases the bottom and second-bottom material boxes during the material distribution process through the reciprocating motion of the baffle in the horizontal plane, achieving an effective transition when the upper and lower material boxes are separated, and ensuring the stability and continuity of the overall material distribution process. The material distribution assembly is controlled by the linkage of the lifting mechanism and the clamping mechanism, adopting a rising-clamping-falling-releasing material distribution method to ensure that the material boxes can fall vertically and smoothly onto the conveyor belt after being detached from the stacked state, effectively preventing tilting, deviation, or jamming. The baffle assembly and the material distribution assembly work together to simplify the control logic and drive structure, reducing the complexity of the equipment and maintenance costs.

[0020] In addition, each pair of baffles is arranged on the outside of opposite sides of the material feeding channel in the horizontal direction, and all baffles are at the same height, forming at least one set of material blocking structures arranged on opposite sides of the material feeding channel in the horizontal direction. This symmetrical layout makes the material box subjected to balanced force during material blocking, further improving the stability and reliability of the material blocking process and facilitating accurate material distribution.

[0021] In this embodiment of the utility model, there is a clear logical sequence between the actions of the material blocking component and the material distributing component. It can be programmed and controlled by, but is not limited to, a PLC or industrial control system to achieve fully automated operation. The coordinated action of the material blocking component and the material distributing component can be set to a periodic cycle mode, which is suitable for stable material feeding of material boxes on continuous production lines and improves the overall line cycle efficiency.

[0022] In addition, this utility model embodiment also provides several optional implementation methods. The specific implementation method section of this specification will provide a detailed description and explanation of the specific structure and functional effects of these optional implementation methods.

[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] First aspect This embodiment provides a material box feeding device, referring to... Figures 1 to 3 The material box feeding device includes a hopper assembly 100, a material blocking assembly 200, and a material distribution assembly 300.

[0034] Specifically, the hopper assembly 100 has a discharge channel for multiple stacked material boxes 400 to fall into; Reference Figure 3 , Figure 4 and Figure 5 The material blocking assembly 200 includes a material blocking assembly mounting frame 2, a rotating mechanism mounted on the material blocking assembly mounting frame 2, and at least two baffles 3 connected to the rotating mechanism. The baffles 3 extend horizontally, with each pair of baffles 3 positioned on opposite sides of the material feeding channel along the horizontal direction, and all baffles 3 at the same height. The rotating mechanism drives all baffles 3 to rotate in the horizontal plane so that the baffles 3 support or release the edge of the bottommost (last layer from top to bottom) or second-to-last (second-to-last layer from top to bottom) material box 400 within the material feeding channel.

[0035] Reference Figure 4 The material distribution assembly 300 includes a lifting mechanism 6 and a clamping mechanism 9. The clamping mechanism 9 is connected to the actuating end of the lifting mechanism 6 and clamps or releases the edge of the bottommost (last layer from top to bottom) material box 400 in the material feeding channel. The lifting mechanism 6 is mounted on the lifting mechanism mounting base 7 and lifts and lowers along with the clamping mechanism 9. Specifically, the lifting mechanism 6 has various optional configurations, including but not limited to a pneumatic (or hydraulic) push-pull structure formed by the cooperation of a cylinder (or hydraulic cylinder) and a piston rod, with the actuating end being the end of its piston rod away from the cylinder (or hydraulic cylinder); or a linear guide slider structure composed of a motor, a ball screw, a screw nut seat, and a slider, with the actuating end being the slider fixed to the screw nut seat; or other linear drive structures.

[0036] In operation, a material box transport line is provided, which includes an operating table, a horizontal conveyor belt and the aforementioned material box feeding device, such that the horizontal conveyor belt is mounted above the operating table and below the unloading channel; the upper ends of the baffle 3 and the clamping mechanism 9 are both located above the horizontal conveyor belt.

[0037] Reference Figures 1 to 3 : In the initial state, the bottom material box 400 in the feeding channel is supported by the baffle assembly 200. Specifically, its rotating mechanism drives all the baffles 3 to rotate in the horizontal plane so that one end of each baffle 3 is screwed into the feeding channel to support the edge of the bottom material box 400. Then, the material distribution component 300 clamps the edge of the bottom material box 400. Specifically, its lifting mechanism 6 drives the clamping mechanism 9 to be located on the outside of the bottom material box 400, and then the clamping mechanism 9 closes and clamps the edge of the bottom material box 400. Next, the material blocking assembly 200 releases the bottom material box 400, that is, its rotating mechanism drives the baffle 3 to rotate in the horizontal plane so that the baffle 3 rotates out of the feeding channel to release the bottom material box 400. Next, the material distribution component 300 clamps the bottom material box 400 and lowers it by the stacking height of one material box. The rotating mechanism of the baffle component 200 drives the baffle 3 to rotate in the horizontal plane so that one end of the baffle 3 is screwed back into the material feeding channel to support the edge of the box of the next bottom material box 400. Next, the material distribution component 300 clamps the bottom material box 400 and descends until the bottom material box 400 falls onto the horizontal conveyor belt, and the clamping mechanism 9 opens to release the bottom material box 400. Repeat the above process to feed the stacked material boxes onto the horizontal conveyor belt.

[0038] In the material box feeding device provided in this embodiment, the baffle assembly 200 dynamically supports and releases the bottom and second-bottom material boxes 400 during the material distribution process through the reciprocating motion of the baffle 3 in the horizontal plane, achieving an effective transition when the upper and lower material boxes 400 separate, and ensuring the stability and continuity of the overall material distribution process. The material distribution assembly 300 is controlled by the linkage of the lifting mechanism 6 and the clamping mechanism 9, adopting an upward-clamping-downward-release material distribution method to ensure that the material boxes 400 can fall vertically and smoothly onto the conveyor belt after being detached from the stacked state, effectively preventing tilting, deviation, or jamming. The baffle assembly 200 and the material distribution assembly 300 cooperate with each other, simplifying the control logic and drive structure, and reducing the complexity and maintenance cost of the equipment.

[0039] In addition, each pair of baffles 3 are arranged on the outside of opposite sides of the material feeding channel in the horizontal direction, and all baffles 3 are at the same height, forming at least one set of material blocking structures arranged on opposite sides of the material feeding channel in the horizontal direction. This symmetrical layout makes the material box 400 subjected to balanced force during material blocking, further improving the stability and reliability of the material blocking process and facilitating accurate material distribution.

[0040] In this embodiment, there is a clear logical sequence between the actions of the material blocking component 200 and the material distributing component 300. It can be programmed and controlled by, but is not limited to, a PLC or industrial control system to achieve fully automated operation. The coordinated action of the material blocking component 200 and the material distributing component 300 can be set to a periodic cycle mode, which is suitable for stable material supply to the material box 400 on a continuous production line and improves the overall line cycle efficiency.

[0041] Furthermore, referring to Figures 5 to 7 In an optional embodiment of this example, the rotating mechanism in the baffle assembly 200 includes a power output assembly 4 and a linkage assembly 5; the power output assembly 4 is mounted on the baffle assembly mounting frame 2; one end of each baffle 3 is connected to the power output assembly 4 via a set of linkage assemblies 5; the power output assembly 4 drives all the baffles 3 to rotate synchronously in the horizontal plane via the linkage assembly 5. With this design, the spatial layout of the rotating mechanism is more flexible.

[0042] Further optionally, the power output component 4 is a translation drive component, which has a variety of optional configurations. The optional configurations include, but are not limited to, a pneumatic (or hydraulic) push-pull structure formed by the cooperation of a cylinder (or hydraulic cylinder) and a piston rod, with the actuating end being the end of the piston rod away from the cylinder (or hydraulic cylinder); or an electric push rod structure composed of a motor, ball screw, slider and push rod, with the actuating end being the end of the push rod away from the motor; or other linear drive structures. The linkage component 5 includes a slide plate 51, a connecting rod 52, and a rotating shaft 53. A horizontally extending slide rail 21 is provided on the material stop component mounting bracket 2. The slide plate 51 extends horizontally and is slidably mounted on the slide rail 21. The slide plate 51 is fixedly connected to the execution end of the translation drive component. A cam follower 54 is installed at one end of the slide plate 51. The connecting rod 52 extends horizontally and has an elongated hole 521 extending along the length of the connecting rod 52. The sliding limit of the cam follower 54 is located inside the elongated hole 521 on the connecting rod 52. The rotating shaft 53 extends vertically and is arranged on one side of the material discharge channel in the horizontal direction. The lower end of the rotating shaft 53 is rotatably connected to one end of the connecting rod 52. One end of the baffle 3 is fixedly connected to the upper end of the rotating shaft 53. The translation drive component drives the slide plate 51 to slide back and forth along the slide rail 21, causing the connecting rod 52 to swing back and forth in the horizontal plane, so as to cause the rotating shaft 53 to rotate around its own axis, thereby causing the baffle 3 to rotate in the horizontal plane.

[0043] In this optional embodiment, the linkage components are composed of a crank-connecting rod mechanism, which has a relatively stable and reliable torque transmission function, reduces transmission error, improves the accuracy of the position switching of the baffle 3, and can ensure the reliability of the baffle 3 rotating in the horizontal plane to switch positions.

[0044] Continue to refer to Figures 5 to 7In an optional embodiment of this example, every two linkage components 5 share a slide plate 51, wherein each slide plate 51 is equipped with a cam follower 54 at both ends, and the cam follower 54 at both ends is respectively slidably limited inside the elongated hole 521 provided on the connecting rod 52 of a linkage component 5.

[0045] In this optional embodiment, one slide plate 51 can simultaneously drive two linkage components 5, improving the linkage between the components. When the translation drive component drives the slide plate 51 to slide back and forth along the slide rail 21, the two linkage components 5 will move synchronously, improving the coordination and consistency of the rotation of the baffle 3 in the horizontal plane. In addition, by sharing one slide plate 51 to simultaneously drive two linkage components 5, the number of slide plates 51 required is reduced, simplifying the structure of the entire baffle assembly 200. The number of parts is reduced, lowering the structural complexity of the baffle assembly 200. This not only facilitates manufacturing and assembly but also reduces potential failure points, improving the structural reliability and operational stability of the baffle assembly 200.

[0046] In an optional embodiment of this example, the translation drive assembly has multiple sets, the same number as the slide plates 51, and each translation drive assembly drives each slide plate 51 to slide back and forth along the slide rail 21. In this optional embodiment, each slide plate 51 can move more precisely along a predetermined path and speed, reducing the alignment complexity during baffle 3 assembly caused by multiple slide plates 51 sharing a single drive source.

[0047] Additionally, refer to Figures 5 to 7 In an optional embodiment of this example, the end of the baffle 3 facing the material feeding channel is provided with an intercepting end 301. The thickness of the intercepting end 301 is less than the thickness of the rest of the baffle 3, and the width of the intercepting end 301 is greater than the width of the rest of the baffle 3. In this optional embodiment, because the intercepting end 301 is thinner, it can reduce friction with the material box when inserted into the gap between two adjacent material boxes, avoiding wear on the material box. This is beneficial to the smoothness of the intercepting end 301 when entering and exiting between the edges of two stacked material boxes, reducing the risk of jamming and blockage. The larger width of the intercepting end 301 maintains a certain structural strength while reducing the thickness, giving the intercepting end 301 a large load-bearing capacity, which can reliably intercept and support stacked multi-layer material boxes.

[0048] In an optional embodiment of this example, the baffle assembly 200 includes four baffles 3, which are distributed circumferentially along the outer side of the material feeding channel. This optional embodiment improves the uniformity of force on the material box when supporting it, reduces the damage rate of the material box when blocked by the baffle assembly 200, and ensures the smoothness of the material dispensing and feeding operations.

[0049] In this embodiment, the material distribution component 300 has at least two clamping mechanisms 9. Each pair of clamping mechanisms 9 is arranged on the outside of opposite sides of the material feeding channel in the horizontal direction. Compared with clamping the edge of the material box 400 on one side, this clamping method of clamping the edge of the material box 400 on both sides or multiple sides is more stable in clamping the material box 400 and can effectively prevent the material box 400 from falling off.

[0050] Furthermore, the clamping mechanism 9 has various optional structural types, including but not limited to, including a finger-grip cylinder and a gripper, with the gripper cylinder driving the gripper to open and close to achieve the clamping and releasing functions. To reduce the structural complexity of the device, in the optional embodiments of this example, such as... Figure 4 As shown, the material distribution assembly 300 also includes a material distribution assembly mounting frame 8. Each clamping mechanism 9 includes a clamping arm 91, a horizontal telescopic mechanism 92, and a clamping block 93. The lower end of the clamping arm 91 is fixedly connected to the material distribution assembly mounting frame 8. The horizontal telescopic mechanism 92 is installed on the upper end of each clamping arm 91. The clamping block 93 is fixedly connected to the actuating end of the horizontal telescopic mechanism 92, and the clamping block 93 has a clamping groove 931 on the side facing the material feeding channel. Furthermore, the clamping grooves 931 on the clamping blocks 93 of all clamping mechanisms 9 are at the same height. The horizontal telescopic mechanism 92 drives the clamping block 93 to extend towards the inside of the material feeding channel so that the clamping groove 931 clamps the edge of the bottommost material box 400 in the material feeding channel. Specifically, a horizontal mounting plate is fixedly connected to the upper end of each clamping arm 91, and the horizontal telescopic mechanism 92 is installed on the horizontal mounting plate. The horizontal telescopic mechanism 92 has a variety of optional configurations, including but not limited to a pneumatic (or hydraulic) push-pull structure formed by the cooperation of a cylinder (or hydraulic cylinder) and a piston rod, with the actuating end being the end of the piston rod away from the cylinder (or hydraulic cylinder); or an electric push rod structure composed of a motor, ball screw, slider and push rod, with the actuating end being the end of the push rod away from the motor; or other linear drive structures.

[0051] In this optional embodiment, all clamping blocks 93 are located at the execution end of the horizontal telescopic mechanism 92, and the clamping slots 931 on each clamping block 93 are at the same height, ensuring uniform force on the edge of the material box 400 during clamping and improving the symmetry and stability of the clamping action. In addition, the lower end of the clamping arm 91 is fixedly connected to the material distribution component mounting frame 8, and the upper end is uniformly equipped with the horizontal telescopic mechanism 92. The horizontal telescopic mechanism 92 directly drives the clamping block 93 to move, making the positioning more accurate and avoiding the problem of offset or shaking during clamping caused by installing the horizontal telescopic mechanism 92 at the lower end of the clamping arm 91, further improving the clamping stability.

[0052] Alternatively, each clamping arm 91 is a vertically extending rod structure, and a guide sleeve 911 is provided on the outside of each clamping arm 91. The guide sleeve 911 is used to fix and install on the operating table and communicate with the through hole provided on the operating table for the clamping arm 91 to pass through, so as to limit the clamping arm 91.

[0053] In this optional embodiment, the guide sleeve 911 limits the movement of the clamping arm 91, which maintains linear motion when moving up and down, avoiding unnecessary lateral deviation. This improves the positioning accuracy of the clamping block 93 when clamping the material box 400. In addition, the guide sleeve 911 not only provides a limiting function but also plays a certain protective role, reducing direct friction between the clamping arm 91 and the operating table and reducing wear.

[0054] In an optional embodiment of this example, the hopper assembly 100 includes a frame comprising multiple columns 11 and a fixing frame 12 connecting the multiple columns 11, with the multiple columns 11 enclosing a discharge channel. In this optional embodiment, the discharge channel enclosed by the multiple columns 11 can precisely control the material box to fall vertically, improving feeding efficiency. At the same time, a large gap is formed between the multiple columns 11, allowing the baffle 3 and the upper part of the clamping mechanism 9 (e.g., clamping block 93) to pass through, satisfying the functions of blocking and distributing materials while possessing a certain structural strength and a small volume, thus improving space utilization.

[0055] In an optional embodiment of this example, the stop assembly 200 further includes multiple guide sleeves 531, with each rotating shaft 53 corresponding to and passing through a guide sleeve 531. The guide sleeves 531 are fixedly installed on the operating table and communicate with shaft holes provided on the operating table for the rotating shafts 53 to pass through, thereby limiting the movement of the rotating shafts 53. In this optional embodiment, limiting the rotating shafts 53 by the guide sleeves 531 can effectively control the movement trajectory of the rotating shafts 53, making the rotation of the rotating shafts 53 more stable and further improving the movement accuracy of the stop assembly 200. At the same time, the presence of the guide sleeves 531 can reduce the direct contact and friction between the rotating shafts 53 and the operating table, reducing wear and extending the service life of the rotating shafts 53.

[0056] Second aspect This embodiment also provides a material box transport line, which includes an operating table, a horizontal conveyor belt, and a material box feeding device provided in any optional embodiment of the first aspect.

[0057] The horizontal conveyor belt is mounted above the operating platform and below the unloading channel; the baffle 3 and clamping block 93 are located above the horizontal conveyor belt, the baffle assembly mounting frame 2 and the power output assembly 4 are located below the operating platform, and the material distribution assembly mounting frame 8, the lifting mechanism mounting seat 7 and the lifting mechanism 6 are all located below the baffle assembly mounting frame 2.
