Description

Technical Field

[0001] This utility model belongs to the technical field of assembly line equipment, and relates to material packing devices, and in particular to an online bag replacement machine. Background Technology

[0002] A bag replenishment machine is a piece of equipment used in automated production lines to detect and replenish missing products in stacks of bagged materials, ensuring that the quantity in each stack is consistent before boxing or consolidation. In existing technologies, there are often problems with stable bag gripping or low replenishment efficiency during the process of replenishing products to the stack. To address these issues, researchers have conducted extensive research and proposed various solutions.

[0003] For example, Chinese patent literature discloses a product packing system [Application No.: CN201420540079.2], including a product feeding conveyor belt, a box feeding conveyor belt, a packing device, and a bag replenishment device. The packing device includes a mechanical gripper with vacuum suction cups. The packing device also includes a vacuum sensor and a counting control module. The vacuum sensor is located on the mechanical gripper and detects the vacuum level on the surface of each vacuum suction cup when it grips the product, transmitting the detection signal to the counting control module. The counting control module is connected to the bag replenishment device, which includes a storage box and bag replenishment suction cups. Based on the counting results, the counting control module controls the bag replenishment suction cups to grab products from the storage box and replenish them in the box that moves onto the box feeding conveyor belt to the bag replenishment device side. This utility model identifies and counts instances where the mechanical gripper fails to grab products, and replenishes the missing products in the packaging box accordingly.

[0004] While the above solution has a bag replenishment function, its overall replenishment efficiency is low. Furthermore, during use, products tend to accumulate at the bottom of the storage box, hindering the product retrieval process. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing an online bag-repairing machine with high bag-repairing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An online bag replenishment machine includes a frame, on which a storage area is provided on one side of a box conveying unit. Between the storage area and the box conveying unit, there is a material handling robot capable of moving the bags in the storage area into the boxes conveyed by the box conveying unit. The storage area is provided with at least one storage rack, and each storage rack is provided with at least one radial limiting structure for preventing vertically stacked bags from collapsing. The storage rack has a bag lifting opening, and a bag lifting plate is provided inside the bag lifting opening. The bag lifting plate is connected to a lifting drive mechanism.

[0007] The material handling robot moves the bags from the storage area into the box to achieve automatic bag replenishment. At the same time, as the material strip in the storage rack decreases, the bag lifting plate continuously lifts the remaining bags, making it easier for the material handling robot to pick up the materials accurately, thus improving the bag replenishment efficiency.

[0008] In the aforementioned online bag-replenishing machine, the material-picking robot includes several suction cup units, which are fixed to a suction cup frame. The suction cup frame is connected to an XZ moving mechanism. The XZ moving mechanism is responsible for moving the material-picking robot in the horizontal and vertical directions, ensuring that the robot can accurately position itself to the target location on the material bags in the storage area and on the box conveying unit.

[0009] In the aforementioned online bag-replenishing machine, the radial limiting structure for the bag body includes at least two diagonally arranged vertical baffles with an L-shaped cross-section. These vertical baffles enclose a stacking area for vertically stacking the bags, and are connected to a storage rack. The diagonally arranged L-shaped vertical baffles form a stacking area for vertically stacking the bags. This design makes the bags more stable during stacking, less prone to collapse or tilting, thus ensuring neat arrangement and smooth removal of the bags.

[0010] In the aforementioned online bag-replenishing machine, a slanted adjustment structure is provided between the vertical baffles and the storage rack, allowing for adjustment of the distance between the two diagonal vertical baffles. This slanted adjustment structure allows for flexible adjustment of the distance between the diagonal vertical baffles according to different specifications or sizes of bags. This design ensures that the bags can be stably stacked vertically on the storage rack and enables the online bag-replenishing machine to handle a wider variety of bags, significantly improving the equipment's versatility and flexibility.

[0011] In the aforementioned online bag-repairing machine, the inclined adjustment structure includes a baffle base located at the bottom of the vertical baffle. The baffle base has at least one oblique slot, parallel to the line connecting the inner angles of the two vertical baffles. The storage rack has positioning holes that mate with the oblique slots. The baffle base and the storage rack are fixed together by bolts passing through the oblique slots and positioning holes. This mating design of the positioning holes and oblique slots ensures the stability of the vertical baffles after adjustment. The bolts passing through the oblique slots and fixing to the positioning holes effectively prevent movement or tilting of the vertical baffles, thereby improving the stability and reliability of the online bag-repairing machine.

[0012] In the aforementioned online bag-replenishing machine, the baffle base has two parallel, angled slots. These two parallel slots engage with positioning holes on the storage rack and are secured with bolts, forming a stable support structure. This design prevents the vertical baffle from tilting or collapsing under the pressure of the bag or other external forces.

[0013] In the aforementioned online bag-repairing machine, the lifting drive mechanism includes a top material frame connected to the bottom of the bag lifting plate, and the top material frame is connected to a linear drive. The connection design between the top material frame and the linear drive enhances the stability and reliability of the entire lifting drive mechanism. This design reduces lifting failures caused by mechanical vibration or instability, thereby improving the overall performance and efficiency of the online bag-repairing machine.

[0014] In the aforementioned online bag-refilling machine, the linear drive includes a ball screw linear module disposed between the storage rack and the box conveying unit. The ball screw linear module is fixed to the frame, and its slider is connected to the bottom of the bag lifting plate via a top material rack. The ball screw linear module can precisely control the movement position of the bag lifting plate, ensuring that the bag is accurately moved to the designated position.

[0015] In the aforementioned online bag-refilling machine, the frame is equipped with an inlet and an outlet for the box conveying unit to pass through, forming a material passage. A pressure plate is positioned above the material passage and is connected to a pressure plate lifting drive mechanism. The pressure plate is positioned above the material passage and moves up and down via the pressure plate lifting drive mechanism. This design ensures stable pressure is applied to the box during conveying, facilitating subsequent processing.

[0016] In the aforementioned online bag-refilling machine, the pressing plate lifting drive mechanism includes at least one guide rod passing through the pressing bracket. The lower end of the guide rod is connected to the pressing plate, and the pressing bracket is connected to the machine frame. A linear drive cylinder is provided between the pressing bracket and the pressing plate. The guide rod passing through the pressing bracket and its lower end connected to the pressing plate provides a stable lifting path, reduces the swaying of the pressing plate during lifting, and thus ensures the accuracy of the pressing action.

[0017] Compared with existing technologies, the advantages of this online bag replenishment machine are: 1. It has a storage area structure design that makes it easier to remove bags. 2. It is designed to replenish multiple bags at a time, resulting in higher overall bag replenishment efficiency. 3. It has a pressing mechanism design, which facilitates subsequent processes.

Detailed Implementation

[0027] like Figures 1 to 8 As shown, this online bag replenishing machine includes a frame 1. The frame 1 has a storage area 3 located on one side of the box conveying unit 2. Between the storage area 3 and the box conveying unit 2, there is a material handling robot 4 that can move the material bags 31 in the storage area 3 to the box 21 conveyed by the box conveying unit 2. The storage area 3 has a storage rack 32. The storage rack 32 has at least two radial limiting structures 33 that can prevent the vertically stacked material bags 31 from collapsing. The storage rack 32 has two material bag lifting openings 34. A material bag lifting plate 35 is provided in the material bag lifting opening 34. The material bag lifting plate 35 is connected to a lifting drive mechanism 36.

[0028] In this embodiment, the material bag 31 located in the storage rack 32 is picked up by the material picking robot 4 and moved to the box 21 located on the box conveying unit 2 to realize the bag replenishment function. At the same time as bag replenishment, the lifting drive mechanism 36 continuously drives the material bag lifting plate 35 in the material bag lifting port 34 to lift upward, so that the material bag 31 is always in a position that is easy for the material picking robot 4 to pick up, which has the effect of improving the stability and efficiency of bag replenishment.

[0029] like Figure 1 and 2 As shown, the frame 1 includes a front access port 14 and a rear access port 15 located on the front and rear sides. A front door panel 141 and a rear window 151 that are transparent and openable are provided in the front access port 14 and the rear access port 15. Above the inlet 11 and outlet 12 on the left and right sides of the frame 1, there are transparent side windows 16.

[0030] More specifically, the material handling robot 4 includes four suction cup units 41, which are fixed on the suction cup frame 42 and connected to the XZ moving mechanism 5.

[0031] like Figure 7 As shown, the XZ moving mechanism 5 includes an X moving shaft 51 mounted on the frame 1, an X moving slider 52 mounted on the X moving shaft 51, a vertically mounted Z moving shaft 53 mounted on the X moving slider 52, a Z moving slider 54 mounted on the Z moving shaft 53, and a suction cup holder 42 connected to the Z moving slider 54.

[0032] More specifically, the radial limiting structure 33 of the bag body includes two diagonally arranged vertical baffles 331 with an L-shaped cross-section. The vertical baffles 331 together form a stacking area 332 for vertically stacking the bags 31. The vertical baffles 331 are connected to the storage rack 32.

[0033] In this embodiment, a pair of sensors 322 for detecting the position of the material bag 31 are provided on the left and right sides of the storage rack 32 at the top height of the vertical baffle 331, and an outwardly extending expansion structure 336 is provided at the top of the vertical baffle 331, which facilitates the material picking robot 4 to pick up materials and facilitates the replenishment of the material bag 31.

[0034] More specifically, a diagonal adjustment structure 333 is provided between the vertical baffle 331 and the storage rack 32, which can adjust the distance between the two diagonal vertical baffles 331.

[0035] like Figure 5As shown, the oblique adjustment structure 333 includes a baffle base 334 disposed at the bottom of the vertical baffle 331. The baffle base 334 is provided with at least two strip-shaped oblique holes 335. The strip-shaped oblique holes 335 are parallel to the line connecting the inner angles of the two vertical baffles 331. The storage rack 32 is provided with positioning holes 321 that can cooperate with the strip-shaped oblique holes 335. The baffle base 334 and the storage rack 32 are fixed by bolts passing through the strip-shaped oblique holes 335 and the positioning holes 321.

[0036] More specifically, the baffle base 334 is provided with two strip-shaped oblique holes 335, and the two strip-shaped oblique holes 335 are parallel to each other.

[0037] More specifically, the lifting drive mechanism 36 includes a top material frame 361 connected to the bottom of the bag lifting plate 35, and the top material frame 361 is connected to the linear drive 362.

[0038] More specifically, the linear actuator 362 includes a ball screw linear module 363 disposed between the storage rack 32 and the box conveying unit 2. The ball screw linear module 363 is fixed on the frame 1, and the slider 364 of the ball screw linear module 363 is connected to the bottom of the bag lifting plate 35 through the top material rack 361.

[0039] In this embodiment, the bottom end of the top material frame 361 is connected to the slider 364, and the top material frame 361 is connected to the material bag lifting plates 35 in the two material bag lifting ports 34 respectively, so as to realize the synchronous control of the material bag lifting plates 35 on both sides.

[0040] More specifically, the frame 1 is provided with an inlet 11 and an outlet 12 for the box conveying unit 2 to pass through. A material passage 13 is formed between the inlet 11 and the outlet 12. A pressure plate 61 is provided above the material passage 13. The pressure plate 61 is connected to the pressure plate lifting drive mechanism 6.

[0041] In this embodiment, the box conveying unit 2 includes a conveyor belt 22 connected to the production line, which is disposed in the material passage 13. The box 21 is disposed on the conveyor belt 22. The material handling robot 4 is disposed upstream of the conveyor belt 22. The material pressing mechanism is disposed downstream of the conveyor belt 22.

[0042] More specifically, the pressure plate lifting drive mechanism 6 includes at least one guide rod 63 passing through the pressure support 62. The lower end of the guide rod 63 is connected to the pressure plate 61. The pressure support 62 is connected to the frame 1. A linear drive cylinder 64 is provided between the pressure support 62 and the pressure plate 61.

[0043] The working principle of this embodiment is that after the box 21 from the upstream of the production line is transported to the bag replenishment position by the conveyor belt 22, the X-moving slider 52 drives the picking robot 4 to move to the position above the storage area 3, and the Z-moving slider 54 drives the picking robot 4 to descend, and the suction cup unit 41 picks up the corresponding number of bags 31; then the XZ moving mechanism 5 drives the picking robot 4 to the top of the box 21, and the suction cup unit 41 releases to replenish the corresponding number of bags 31 into the box 21.

[0044] Simultaneously, the slider 364 of the linear actuator 362 ball screw linear module 363 rises, lifting the bag lifting plate 35 via the top material frame 361, thereby ensuring that the bag 31 in the stacking area 332 is always kept in a position that is easy for the picking robot 4 to pick up. If it is observed that the bag 31 needs to be replenished, the front door panel 141 at the front of the frame 1 is opened for replenishment.

[0045] Afterwards, the conveyor belt 22 carries the refilled box 21 to the position below the pressing plate 61. The linear drive cylinder 64 drives the pressing plate 61 to press down, and at the same time the guide rod 63 guides the pressing action of the pressing plate 61 to press the bag 31 in the box 21 tightly. Then the conveyor belt 22 carries the box 21 into the next process.
