Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] Example 1, please refer to the attached drawings of the specification Figure 1-Figure 7 In the present invention, a material management system for a digital production line with automatic material preparation, transportation, cutting and discharging includes an inventory unit, a material preparation unit 1, an automatic feeding unit 2, an automatic cutting unit 3 and an automatic discharging unit 4, and also includes a control unit. The control unit is integrated in a touch screen 37 in the automatic cutting unit 3, and is respectively connected to the material preparation unit 1, the automatic feeding unit 2, the automatic cutting unit 3 and the automatic discharging unit 4 through power and signal lines. The control unit includes a material management control unit, a remote monitoring control unit and a finished product tracking control unit; the remote monitoring control unit, the material management control unit and the finished product tracking control unit respectively establish signal connections.

[0060] The material management control unit includes a distribution control system, an automatic feeding control system, an automatic cutting control system and an automatic discharging control system; the distribution control system establishes signal connections with the inventory unit and the material preparation unit 1 respectively.

[0061] The distribution control system controls the inventory unit and the material preparation unit 1 ; the automatic feeding control system controls the automatic feeding unit 2 , the automatic cutting control system controls the automatic cutting unit 3 , and the automatic discharging control system controls the automatic discharging unit 4 .

[0062] The remote monitoring control unit includes a mobile terminal device, multiple camera devices connected to the mobile terminal device by signal, and a cloud platform. The mobile terminal device establishes communication connections with the on-site inventory unit, material preparation unit 1, automatic feeding unit 2, automatic cutting unit 3 and automatic discharging unit 4 through the Modbus protocol; camera devices are respectively arranged at the inventory unit, material preparation unit 1, automatic feeding unit 2, automatic cutting unit 3 and automatic discharging unit 4, and the camera devices establish signal connections with the cloud platform. The finished product tracking control unit includes a material information storage management system and a QR Code two-dimensional code establishment system, and the QR Code two-dimensional code can read material information.

[0063] The steps to establish a QR Code system include:

[0064] A. Determine the information that needs to be encoded in the QR Code, including the basic information of the cut material;

[0065] B. Choose a QR Code generator software or mobile app;

[0066] C. Paste the basic information of the material into the QR Code generator software or mobile app to automatically generate a QR code;

[0067] D. Apply the generated QR Code image to the material information storage and management system to achieve material tracking management.

[0068] In this embodiment, this digital production line is used to cut a kind of square material. The automatic feeding unit 2, the automatic cutting unit 3 and the automatic discharging unit 4 are arranged in sequence. The material preparation unit 1 is set on one side of the automatic feeding unit 2. The material preparation unit 1 is used to store the square material. The automatic feeding unit 2 is used to feed the square material into the automatic cutting unit 3. The automatic cutting unit 3 is used to cut the square material. The automatic discharging unit 4 is used to transport the cut square material.

[0069] Through the control unit, the inventory unit, the material preparation unit 1, the automatic feeding unit 2, the automatic cutting unit 3 and the automatic discharging unit 4 are automatically integrated together to realize automatic unloading, cutting and feeding. The control unit accurately controls the inventory unit, the material preparation unit 1, the automatic feeding unit 2, the automatic cutting unit 3 and the automatic discharging unit 4 to better meet production needs and improve production efficiency.

[0070] The video data captured by multiple cameras are stored on the cloud platform, so that every step of the material process is recorded. The remote monitoring control unit can use the real-time data on the cloud platform to remotely monitor the material management control unit in real time through mobile terminal devices. It can also play back and view whether the control of materials is reasonable and the whereabouts of the materials.

[0071] By scanning the QR code in the finished product tracking control unit with the scanner, you can see the basic information of the material. This is achieved by automatically generating a QR code with the basic information of each cubic material in a coded mode and storing it in the material information storage management system. The material information storage management system is connected to the cloud platform, so every step of the material will also be recorded by the material information storage management system, and the information in the QR code will also be updated. By scanning the QR code, you can know the inventory of each material, which step it is in, and the whereabouts of the material, which facilitates the traceability management of the material.

[0072] Embodiment 2, as Figure 1As shown, in order to facilitate automatic material retrieval, the material preparation unit includes one or more walking robots and one or more mobile material preparation racks 11; the walking robots establish signal connections with the inventory unit and the mobile material preparation rack 11 respectively through the distribution control system; a weight detection sensor is arranged on the mobile material preparation rack 11, and a signal connection is established between the weight detection sensor and the walking robot; and navigation devices are arranged on the mobile material preparation rack 11 and the walking robot.

[0073] When it is time to pick up materials, one and / or more walking robots and one and / or more mobile stock racks 11 automatically navigate to the inventory unit, and one and / or more walking robots take out square materials from the inventory unit and put them on the mobile stock rack 11. When the weight detection sensor senses the maximum load, it sends a signal that no more materials can be loaded. Because the mobile stock rack 11 is connected to the distribution control system signal, and the distribution control system is connected to the walking robot signal, the walking robot will receive a signal that the mobile stock rack 11 is full of materials and will stop loading materials. After that, one and / or more walking robots and one and / or more mobile stock racks 11 automatically navigate back to the location of the stock rack.

[0074] One or more walking robots are also used to monitor whether the square materials on the automatic feeding unit 2 are reduced, so as to grab the square materials from the mobile material preparation rack 11 and place them on the automatic feeding unit 2.

[0075] Embodiment 3, automatic feeding unit 2, such as Figure 2 As shown, it includes several longitudinal feeding tracks and transverse feeding tracks. The transverse feeding track is fixedly connected to one end of the longitudinal feeding track and its conveying direction is perpendicular to the conveying direction of the longitudinal feeding track. In order to better support the automatic feeding unit 2, a support frame 21 fixed to the ground is arranged under the longitudinal feeding track and the transverse feeding track. The longitudinal feeding track is a chain conveying track.

[0076] A plurality of longitudinal feeding tracks are fixedly mounted on the support frame 21, and a chain 22 is arranged on the longitudinal feeding track. The chain 22 is driven by a motor. A transmission shaft is arranged on the outer side of the support frame 21, and the motor drives the transmission shaft to rotate. The gear on the transmission shaft drives the chain 22 to rotate. During the rotation process, the chain 22 will drive the square materials placed on it to be transmitted forward, and finally fall on the transverse feeding track. At this time, the automatic feeding control system will control the longitudinal feeding track to stop moving. Here, a sensor is installed on the transverse feeding track and is electrically connected to the control unit so that the control unit can receive information that there are square materials on the transverse feeding track, so as to make an instruction to stop the chain 22 on the longitudinal feeding track. It can also calculate the length of the chain 22 from the beginning of movement to the transverse feeding track. After transmitting this length, the automatic feeding control system controls the chain 22 on the longitudinal feeding track to stop moving, thereby issuing an instruction to allow the transverse feeding track to start transmitting square materials. The chain 22 of the longitudinal feeding track can be adjusted to be loose and tight by a tensioning mechanism. The tensioning mechanism is a prior art and will not be described in detail.

[0077] Continue to refer to Figure 2 The transverse feeding track is in contact with the cutting plate, and includes a transverse feeding bottom plate 27, a positioning cylinder 24, a plurality of conveying components and a driving wheel 26. The plurality of conveying components are fixedly arranged on the upper plate surface of the transverse feeding bottom plate 27 and are arranged along the length direction of the transverse feeding bottom plate 27. It includes a base, an axis, a connecting rod, a limiting column 23, a roller component 25 and a limiting cylinder. The base is fixed to the transverse feeding bottom plate 27 with bolts. The base passes through the axis, and a plurality of roller components 25 are sleeved on the axis. The rolling direction of the roller component 25 is consistent with the feeding direction. A limiting column 23 perpendicular to the axis is fixedly connected to one end of the axis, and a connecting rod is hinged at the other end of the axis. A long connecting rod is hinged at the other end of the connecting rod. The connecting rods of a plurality of conveying components are hinged on the long connecting rod. The long connecting rod is driven by the limiting cylinder, and the long connecting rod is hinged at On the side of the transverse feeding bottom plate 27, the long connecting rod is driven to move left and right through the output end of the limiting cylinder, driving the connecting rod to move, and finally driving the limiting column 23 to fall down or stand upright. The roller assembly 25 is on the same horizontal plane as the longitudinal feeding track. The positioning cylinder 24 is arranged along the length direction of the transverse feeding bottom plate 27. The positioning cylinder 24 is on the outside of the supporting frame 21. The limiting column 23 and the positioning cylinder 24 are used to limit the other material. The driving wheel 26 is located above the transverse feeding bottom plate 27, and the driving wheel 26 is higher than the roller assembly 25.

[0078] The roller assembly 25 is composed of a plurality of rollers connected in series via shafts. The rollers can not only bear the weight of the square materials, but also allow the square materials to be transported forward.

[0079] When the automatic feeding control system receives information that there is square material on the horizontal feeding track, it senses the square material through the induction sensor, and then through information processing and output, the automatic feeding control system controls the output end of the limit cylinder to extend, and the limit column 23 is driven by the limit cylinder to rotate to a state vertical to the horizontal feeding bottom plate 27, so that the square material can be limited. In order to better limit the position of the square material, a positioning cylinder 24 is also fixedly provided on the side of the support frame 21. The output end of the positioning cylinder 24 extends out, which can also limit the position of the square material and prevent the square material from swinging left and right.

[0080] The driving wheel 26 mounting seat is installed on the side of the supporting frame 21. The driving wheel 26 corresponds to the square material and abuts against the square material above the square material. When the driving wheel 26 rotates, it can not only drive the square material to be stepped forward, but also play a certain pressing effect on the square material. The driving wheel 26 is driven by a motor.

[0081] A visual identifier is installed on the walking robot, which is electrically connected to the distribution control system and can identify the reduction of materials on the longitudinal feeding track. When the material on the longitudinal feeding track is reduced, the distribution control system controls the walking robot to grab the square materials from the mobile material preparation rack 11 and place them on the longitudinal feeding track in time.

[0082] Example 4, reference Figure 3 In the figure, the automatic cutting unit 3 includes a box body 31, a cutting plate, a circular saw slice 32, a clamping plate, a stop pressure block 33 and a discharge port 34. A cutting plate is arranged in the box body 31, and the cutting plate is abutted against the horizontal feeding track. A circular saw slice 32 is arranged on one side of the cutting plate, and clamping plates are arranged on both sides of the cutting plate. A stop pressure block 33 is arranged above the cutting plate, and the stop pressure block 33 is connected to the output end of the stop cylinder. The discharge port 34 is fixed below the end of the cutting plate. An electrical control cabinet 36 and a touch screen 37 with a rotating bracket are connected to the outside of the box body 31. The touch screen 37 is electrically connected to the control unit. Various control systems in the control unit are integrated in the touch screen 37. Various parameter configurations in the distribution control system, automatic feeding control system, automatic cutting control system and automatic discharge control system can be input into the touch screen 37 to realize human-computer interaction.

[0083] When the square material is transmitted into the automatic cutting unit 3, the automatic cutting control system will issue a command to extend the clamping plate in the box 31 toward the direction of the square material to clamp it, and the output end of the stop cylinder drives the stop pressure block 33 to move downward to press the square material to be cut to prevent the saw blade from breaking due to the shaking of the square material during the sawing process. The cutting position is determined according to the cutting speed of the disc saw slice 32 set in the automatic cutting unit 3 and the cutting length of the square material.

[0084] When cutting the square material, the driving wheel 26 stops rotating. When a section of the square material is cut, the driving wheel 26 starts rotating again, and the square material is conveyed forward again, and the next cutting is carried out. The cut square material slides out from the discharge port 34.

[0085] Example 5, reference Figure 4 In the embodiment, the automatic cutting unit 3 also includes a waste conveying mechanism 35 for conveying waste. The waste conveying mechanism 35 is connected to the bottom of the box body 31, and includes a waste conveying motor, a waste conveying channel, a waste conveying chain, a waste frame, and a conveying pipe connected to the bottom of the box body 31. The waste conveying chain rotates in the conveying pipe under the drive of the waste conveying motor. Since the waste conveying chain has grooves, the waste can be conveyed to the outlet of the conveying pipe along with the conveying chain and fall into the waste frame below, and the waste is collected in the waste frame.

[0086] The waste conveying mechanism 35 is free from cleaning the inside of the box body 31, thus saving manpower.

[0087] Example 6, continue to refer to Figure 4 In the embodiment, the automatic discharging unit 4 includes a discharging support frame, a discharging conveying chain plate 41, a protective plate 42 and a slope outlet 43. The discharging conveying chain plate 41 is arranged at the upper end of the discharging support frame, one end of the discharging conveying chain plate 41 corresponds to the discharging outlet 34, protective plates 42 are arranged on both sides of the discharging conveying chain plate 41, and a slope outlet 43 is arranged at the other end of the discharging conveying chain plate 41. The discharging conveying chain plate 41 abuts against the slope outlet 43, so that the cut square material can slide out from the slope outlet 43. The discharging conveying chain plate 41 is driven to rotate by the conveying chain plate motor.

[0088] Example 7, continue to refer to Figure 4 In the embodiment, the automatic discharging unit 4 also includes a sorting mechanism, which is fixedly connected to one side of the end of the discharging conveying chain plate 41. The sorting mechanism includes a pushing frame, a pushing cylinder 44, a pushing plate 45, a baffle plate 46, and a visual sensor. A pushing cylinder 44 is arranged on the plate surface of the pushing frame, and the output end of the pushing cylinder 44 is fixedly connected to the pushing plate 45. Pushing handles are respectively fixedly connected at both ends of the pushing plate 45. The two pushing handles are slidably connected to the pushing frame. A visual sensor is arranged on the end of the protective plate 42 away from the pushing frame. The visual sensor is used to detect whether the length of the square material after being cut is qualified. The baffle plate 46 is slidably arranged on the pushing frame, and close to the side of the slope outlet 43. The baffle plate 46 is driven by the baffle plate cylinder.

[0089] When the cut square material slides from the discharge port 34 to the discharge conveyor chain plate 41, the visual sensor will collect the length of the cut square material product 40 to detect whether it is a qualified product. If the cut square material product 40 is continuously collected to be not a qualified product, it means that the parameters set in the automatic cutting unit 3 are deviated. The visual sensor will transmit the information to the automatic discharge control system, and the automatic discharge control system will feedback the information to the automatic cutting control system. The automatic cutting control system will readjust the parameter information, such as the cutting speed and the cutting line, so that its parameters meet the requirements of qualified products.

[0090] When the visual sensor detects that the cut square material product 40 is not a qualified product, the information is transmitted to the automatic discharging control system. After information processing, the automatic discharging control system controls the material blocking plate 46 to extend to intercept unqualified products, and then controls the output end of the push cylinder 44 to extend, driving the push handle to move forward. A slide rail is provided under the push handle, and the slide rail is fixed on the plate surface of the push rack body, which can make the push handle slide more smoothly on the push rack body, and finally drive the push plate 45 to be pushed out, so as to push the unqualified square material product 40 out of the discharging conveying chain plate 41. Figure 4 It can be seen that at the place where the sorting mechanism corresponds to the discharge conveying chain plate 41, there is no protective plate 42 connected to the discharge conveying chain plate 41, which facilitates the pushing cylinder 44 to push unqualified products out of the discharge conveying chain plate 41.

[0091] Embodiment 8.

The baffle plate 46 and the baffle plate 1 are respectively provided on both sides of the pushing handle. When the unqualified square material product 40 is detected, the baffle plate 46 and the baffle plate 1 are pushed out at the same time to intercept the unqualified square material product 40, and the pushing cylinder 44 pushes out the pushing plate 45 to push out the unqualified square material product 40.

[0092] After the material pushing action is completed, the material pushing cylinder 44, the material blocking plate cylinder and the material blocking plate cylinder 1 return to the original position, driving the material pushing plate 45, the material blocking plate 46 and the material blocking plate 1 to return.

[0093] If the square material product 40 captured by the visual sensor is a qualified product, it will slide smoothly through the discharge conveying chain plate 41 to the slope outlet 43, be collected and enter the next process.
