Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to an intelligent replenishment reciprocating material receiving packaging system, packaging method and storage medium. Background Technology

[0002] Silicon material needs to be packaged in different specifications based on its size. Currently, the coarse weighing and packaging of silicon material generally uses a rotary mechanism, which is set up with three or four rotating stations. One station puts the bag in place, rotates to the next station for weighing and unloading, and then rotates to the next station to receive the bag and put it into a box. Although this rotary mechanism can effectively maintain the efficiency of receiving, there is only one unloading station, and it can only receive one specification of material. If the purpose of packaging two specifications of material is to achieve, an additional machine is required, which will undoubtedly increase the size and complexity of the packaging equipment, and it cannot balance the production capacity of the two types of materials, resulting in a lower overall output. Summary of the Invention

[0003] Therefore, it is necessary to provide an intelligent, reciprocating feeding and packaging system, packaging method, and storage medium to address the problem that existing silicon material packaging systems cannot package materials of two different specifications.

[0004] An intelligent, reciprocating, feeding and packaging system is used for the intelligent and automated packaging of two materials of different specifications. The packaging system includes:

[0005] frame;

[0006] Two feeding mechanisms, each including a hopper, a weighing sensor, and a valve; the hopper is connected to the frame, the weighing sensor is used to detect the weight of the material in the corresponding hopper and generate a corresponding real-time weight signal; the valve is located at the feeding port of the hopper;

[0007] The reciprocating motion mechanism includes a transmission structure, two receiving pipes, and a positioning module; the transmission structure is connected to the frame and is used to drive the two receiving pipes to reciprocate in the direction of the line connecting the two feeding mechanisms; the receiving ports of the two receiving pipes are matched with valves; the positioning module is used to position the two receiving pipes and generate corresponding position signals.

[0008] Two bagging fixtures are connected to the frame and are respectively set at both ends of the motion path of the reciprocating motion mechanism; the bagging fixtures are used to bag the discharge port of the corresponding receiving pipe to hold the material.

[0009] The controller receives real-time weight and position signals and sets a weight threshold. When the real-time weight signal reaches the weight threshold, the controller controls the corresponding valve to open. At the same time, the controller controls the idle receiving pipe to move to the receiving position corresponding to the opened valve according to the position signal. When the real-time weight signal returns to zero, the controller controls the corresponding valve to close and performs the bag removal step.

[0010] As a preferred example, the frame adopts a gantry-type welded frame.

[0011] As a preferred example, the transmission structure includes two motors and two synchronous belts; both motors are connected to the frame, and the output shaft of each motor is connected to one of the synchronous belts respectively, which is used to drive the synchronous belts to rotate; both receiving pipes are slidably connected to the horizontal beam of the frame, and the two receiving pipes are respectively connected to one of the synchronous belts.

[0012] As a preferred example, the motor is a servo motor; the controller is also used to control the output of the motor and receive feedback from the motor to obtain the position signal.

[0013] As a preferred example, the positioning module includes at least four photoelectric sensors, which are respectively set at the material receiving position corresponding to the valve and the bagging position corresponding to the bagging fixture. The photoelectric sensors are used to detect the position of the material receiving pipe and generate the corresponding position signal.

[0014] As a preferred example, the intelligent replenishment reciprocating receiving and packaging system also includes two transfer mechanisms, both of which are set on the movement path of the reciprocating motion mechanism. The transfer mechanisms are used to realize the bag picking step.

[0015] As a preferred example, the transfer mechanism includes a conveyor line and a lifting device and a detection photoelectric sensor installed on the conveyor line; the detection photoelectric sensor is used to detect whether there is a receiving box at the position of the lifting device on the conveyor line, and generates a photoelectric signal if a receiving box is detected; the controller is also used to receive the photoelectric signal, and controls the lifting device to rise when the photoelectric signal is received.

[0016] A smart, reciprocating, material-receiving packaging method, employing the smart, reciprocating, material-receiving packaging system described above, includes the following steps:

[0017] Material is supplied from upstream into the hopper, and the real-time weight of the material in the hopper is detected by a weighing sensor; when the real-time weight reaches the weight threshold, the receiving pipe starts receiving the material.

[0018] When the supply speed of the two materials is the same, the two receiving pipes are responsible for receiving the materials on their respective sides of the feeding mechanism.

[0019] When one material is supplied at a faster rate and the other at a slower rate, while waiting for the slower-supplying material to fill the hopper to the weight threshold, both receiving pipes are activated to receive the faster-supplying material.

[0020] As a preferred example, when the weight of the material in both hoppers reaches the weight threshold at the same time, the receiving pipe shall take priority in receiving the material from the feeding mechanism on its corresponding side.

[0021] A computer-readable storage medium storing a computer program, which, when executed by a processor, implements the control logic of a controller in the intelligent replenishment reciprocating material receiving and packaging system described above, and / or the intelligent replenishment reciprocating material receiving and packaging method described above.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention utilizes a reciprocating dual-station structure design and optimizes the material unloading path to dynamically compensate for unloading at idle stations in real time, achieving seamless real-time switching between the two stations. When the material supply speed at one of the unloading points is relatively fast, the system receives electrical signals such as the current positional relationship between the receiving pipes, material boxes, and hoppers of the two stations. Through logical operations, it decides which idle receiving pipe should complete the receiving task, thereby improving operational efficiency, maximizing production capacity, and effectively solving the problem of uneven production capacity between the two stations.

[0024] 2. This invention utilizes dual servo motors for dual control, enabling the left and right receiving tubes to move in the same or opposite directions, or asynchronously. The PLC central control unit provides real-time feedback on the receiving box information, promptly assigning tasks to the two receiving tubes to ensure continuous production.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Please refer to Figure 1This embodiment provides an intelligent reciprocating material receiving and packaging system, which includes a frame 1, two feeding mechanisms, a reciprocating motion mechanism, two bagging fixtures 4, two transfer mechanisms, and a controller. The frame 1 can be a gantry-type welded frame, with its bottom fixed to the ground. The feeding mechanism includes hoppers 2, weighing sensors, and valves. Two hoppers 2 are fixed side-by-side at the upper end of the frame 1. The weighing sensors are installed on the hoppers 2 to detect the weight of the material in the corresponding hopper 2 and generate corresponding real-time weight signals. The valves are installed at the outlets of the hoppers 2 and control the opening and closing of the outlets according to the controller's instructions.

[0036] The reciprocating motion mechanism in this embodiment includes a transmission structure, two receiving pipes 3, and a positioning module. Specifically, as shown... Figure 2 As shown, the transmission structure includes two motors 6 and two synchronous belts 7. The two motors 6 are symmetrically fixed to the frame 1. The output shaft of each motor 6 is connected to one of the synchronous belts 7. The end of the synchronous belt 7 furthest from the motor 6 is correspondingly sleeved on the rotating shaft 8, thus allowing the synchronous belt 7 to be tensioned and rotated by the motor 6. Both receiving pipes 3 are slidably connected to the horizontal beam of the frame 1, and are located on the same straight line. However, the two receiving pipes 3 are fixedly connected to the two synchronous belts 7 one-to-one via connecting plates, meaning that one motor 6 controls the movement of one receiving pipe 3, and the two motors 6 and the two synchronous belts 7 do not interfere with each other. Therefore, the two synchronous belts 7 can be respectively arranged on the front and rear sides of the frame 1 to prevent interference between them. In another embodiment, the synchronous belt 7 structure can be replaced with a rack and pinion drive. This rack and pinion drive also has two sets, each corresponding to one of the two receiving pipes 3. The function of this rack and pinion drive is the same as that of the synchronous belt 7.

[0037] The receiving tube 3 can be a tubular body with its upper receiving port corresponding to the valve. An automatic clamp is installed on the lower end of its side wall. This automatic clamp is used to clamp the bag and prevent it from falling off when the bag-covering fixture 4 covers the bag at the outlet of the receiving tube 3. Specifically, the automatic clamp may include an electric cylinder and a clamping plate. The electric cylinder is fixed to the receiving tube 3, driving the clamping plate to separate from and engage with the receiving tube 3, thereby clamping the bag opening. A positioning module is used to position the two receiving tubes 3 and generate corresponding position signals. In this embodiment, the positioning module can replace the motor 6 that controls the movement of the receiving tube 3 with a servo motor 6 for positioning. The position signal of the receiving tube 3 is obtained using the servo characteristics of the servo motor 6. In another embodiment, the positioning module may also include at least four photoelectric sensors. Multiple photoelectric sensors are respectively set at the receiving position corresponding to the valve and the bag-covering position corresponding to the bag-covering fixture 4. Compared with the positioning method described above, where the servo motor 6 can obtain position signals in real time, the photoelectric sensor in this embodiment can only detect the position of the receiving tube 3 at a preset position and generate a position signal at the corresponding position.

[0038] Two bagging fixtures 4 are also connected to both ends of the frame 1, and the two bagging fixtures 4 are located on the motion path of the reciprocating motion mechanism. The bagging fixtures 4 can be the existing bagging fixtures 4 of the packaging equipment, which are used to bag the discharge port of the moving receiving pipe 3 to hold the material.

[0039] In this embodiment, the transfer mechanism is responsible for the bag removal step after receiving the bagged material. Specifically, as follows: Figure 3 As shown, the transfer mechanism includes a conveyor line 5, a lifting device 9, a detection photoelectric sensor 10, and an RFID module 11 mounted on the conveyor line 5. The conveyor line 5 is positioned below the receiving pipe 3 and its movement path must pass through the receiving pipe 3 during its arrangement. Empty receiving boxes 12 are continuously delivered from upstream of the conveyor line 5. In one embodiment, the conveyor line 5 can be configured as two segments, with the lifting device 9 located between the two segments. The lifting device 9 may include a lifting cylinder and a conveyor belt. The conveyor belt rotates in the same direction as the conveyor line 5 and is positioned between the two segments. The initial height of the conveyor belt is flush with the conveyor line 5, and the distance between the two ends of the conveyor belt and the conveyor line 5 is minimized. The extension end of the lifting cylinder is connected to the edge of the conveyor belt to drive the conveyor belt up and down. The detection photoelectric sensor 10 is used to detect whether there is a receiving box 12 at the position of the lifting device 9 on the conveyor line 5. If a receiving box 12 is detected, a photoelectric signal is generated. When the controller receives the photoelectric signal, it controls the lifting device 9 to rise. At this point, both the conveyor belt and conveyor line 5 stop operating. The lifting cylinder raises the receiving box 12 on the conveyor belt, so that the receiving box 12 precisely supports the bag on the receiving tube 3 (this raising height can be a preset fixed height). Simultaneously, the RFID module 11 writes information to the receiving box 12. Then, the automatic clamp on the receiving tube 3 releases, and the bag filled with material falls into the receiving box 12. The lifting device 9 then retracts to its initial height. The conveyor belt and conveyor line 5 resume operation. The conveyor belt delivers the material-filled receiving box 12 to the conveyor line 5 until it is transported to the next process.

[0040] One key design feature of this invention lies in the control logic of the packaging system, implemented through a controller. This controller receives the aforementioned real-time weight and position signals and sets a weight threshold. When the real-time weight signal reaches the threshold, the controller opens the corresponding valve. Simultaneously, based on the position signal, the controller moves the idle receiving pipe 3 (i.e., the receiving pipe 3 that has not yet undergone the receiving and bag-removal steps) to the receiving position corresponding to the opened valve. When the real-time weight signal returns to zero, the controller closes the corresponding valve and initiates the bag-removal step.

[0041] In another embodiment, the present invention also provides an intelligent reciprocating feeding and packaging method, which employs the intelligent reciprocating feeding and packaging system described above. The intelligent reciprocating feeding and packaging method includes the following steps:

[0042] Material is supplied from upstream into hopper 2, and the real-time weight of the material in hopper 2 is detected by a weighing sensor. When the real-time weight reaches the weight threshold, receiving pipe 3 starts receiving the material.

[0043] When the supply speed of the two materials is the same, the two receiving pipes 3 are responsible for receiving the materials on their respective sides of the feeding mechanism.

[0044] When one material is supplied at a faster rate and the other at a slower rate, while waiting for the slower-supplying material to fill the hopper 2 to the weight threshold, the two receiving pipes 3 are activated to receive the faster-supplying material.

[0045] When the weight of the material in both hoppers 2 reaches the weight threshold at the same time, the receiving pipe 3 takes priority in receiving the material from the feeding mechanism on its corresponding side.

[0046] Specifically, the working principle of this invention will be explained using a PLC as one application of the aforementioned controller. Two materials of different specifications enter the hopper 2 from upstream. When idle, the receiving pipe 3 is located at the bagging fixture 4 and is bagged, then ready for use. When the weight of the material in the hopper 2 reaches a weight threshold, the receiving pipe 3 on the corresponding side moves to the hopper 2 where the weight threshold has been reached to receive the material. When the weight in the hopper 2 is detected to be zero (when the hopper 2 is discharging material, the upstream material supply stops), the transfer mechanism performs a bag removal step on the receiving pipe 3.

[0047] like Figure 4 As shown, when the conveying cycles of the two conveyor lines 5 are balanced (i.e., the supply speeds of the two materials are the same): the PLC controls the two receiving pipes 3 to synchronously process the receiving work on their respective sides, including a series of actions such as moving the receiving pipe 3, bagging, moving the receiving box 12, and lifting, which constitute one receiving work cycle. The two receiving pipes 3 complete the process synchronously. The two conveyor lines 5 then transfer the fully loaded receiving box 12 to the next process.

[0048] like Figure 5As shown, when the conveying cycles of the two conveyor lines 5 are uneven (i.e., one material is supplied faster and the other slower): when there is a significant difference in the conveying cycles of the two conveyor lines 5 (assuming the initial receiving pipe 3 on the left is A1, the conveyor line 5 on the left is LINE1, the initial receiving pipe 3 on the right is A2, and the conveyor line 5 on the right is LINE2), the signals generated by the detection photoelectric sensor 10 and RFID module 11 on both sides of the conveyor line 5 are different, resulting in different instruction codes received by the PLC. When the signals generated by the detection photoelectric sensor 10 and RFID module 11 of LINE1 are normal (the side with the normal signal is the side with the slower material supply speed. The weight thresholds of the two hoppers 2 are the same, so the time for the weight of the hopper 2 with the slower supply speed to accumulate to the weight threshold is longer than the time for the other hopper 2). After completing one receiving cycle, A1 quickly moves to the receiving position of A2 (at this time, A2 has completed one receiving cycle and is bagging at the bagging station, making room for the corresponding receiving position). After receiving material at A2's receiving position, A1 places the bag on LINE2. After the bag retrieval step, A1 returns to its original working position and performs bagging. Then, A2 receives material from the right-side hopper 2. A1 and A2 then cycle through this process, receiving material from the right-side hopper 2 until the left-side hopper 2 reaches its weight threshold. At this point, A1 returns to its original working position to continue receiving material. Through this operational method, this intelligent, reciprocating, replenishing material receiving and packaging system can increase the production capacity by approximately 60% compared to existing silicon material packaging systems.

[0049] In another embodiment, a computer-readable storage medium is also provided. The computer-readable storage medium stores a computer program. When executed by a processor, the computer program implements the control logic of the controller in the intelligent replenishment reciprocating feeding and packaging system described above, and / or the intelligent replenishment reciprocating feeding and packaging method described above.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
