[0002] Material transport bags can be fixed in the carriage to transport liquid, granular or powdered materials. When the carriage needs to transport other materials, the material transport bags need to be folded, stowed and removed from the carriage. This process requires manual operation, which is labor-intensive, time-consuming and labor-intensive. When the carriage needs to transport liquid, granular or powdered materials, the material transport bags need to be propped up and fixed in the carriage. Because the airbag frame material transport bag includes a bag body made of elastic material, a material pipe integrally fixed above the bag body, and a bladder-shaped frame provided on the bag body, the bladder-shaped frame is an airbag provided along each edge of the rectangular bag body, and the bladder-shaped frame forms a rectangular frame after inflation. During installation, an inflation step is also required. For material yards, when train carriages or queued truck carriages need to be continuously loaded or unloaded, manually installing material transport bags and disassembling and removing material transport bags is very inefficient, which will greatly delay the loading or unloading process.

[0003] How to reduce or eliminate the manual work in installing or removing material transport bags on site and improve efficiency is a technical problem that needs to be solved urgently. Summary of the Invention

[0011] A material transport bag comprises a bag body which is rectangular when propped up and a sac-shaped frame which is made of the same material as the bag body and is integrally provided with the bag body, the sac-shaped frame comprising an upper rectangular air bag, the sac-shaped frame being connected to a conical air inlet pipe, the conical air inlet pipe being plugged into and fitted with the corresponding charging and discharging holes, a plurality of magnetizing electromagnets being fixed circumferentially on the bag body, the magnetizing electromagnets being connected to conical charging and demagnetizing columns, the conical charging and demagnetizing columns being plugged into and fitted with the corresponding charging and demagnetizing holes, a magnetizing electrical connection ring connected to a magnetizing electrical connection spring sheet being provided on the conical charging and demagnetizing columns, a demagnetizing electrical connection ring connected to a demagnetizing electrical connection spring sheet being provided on the conical charging and demagnetizing columns, the conical air inlet pipe and the conical charging and demagnetizing columns being fixed on corresponding iron plates, and the iron plates being fixed at the four corners of the upper surface of the bag body.

[0012] Preferably, the conical air inlet pipe includes a first conical air inlet pipe and a second conical air inlet pipe, and the upper rectangular airbag is connected to the first conical air inlet pipe; the conical charging and demagnetization column includes a first conical charging and demagnetization column and a second conical charging and demagnetization column, and the magnetizing electromagnet includes a first magnetizing electromagnet fixed circumferentially at the upper part of the bag body and a second electromagnet unit fixed circumferentially at the lower part of the bag body, the first magnetizing electromagnet is connected to the first conical charging and demagnetization column, and the second electromagnet unit is connected to the second conical charging and demagnetization column.

[0014] The method for installing the material transport bag using the automatic material loading and unloading device comprises the following steps: S1. At the material transport bag placement position, the telescopic mechanism extends, the first rectangular frame descends, and the two first electromagnet mechanisms at one end of the bottom of the first rectangular frame reach the upper surface of the iron plate corresponding to the wound bag body. The controller activates the first electromagnets of the two first electromagnet mechanisms to magnetize, the upper connecting plate is attracted to the corresponding iron plate, the first conical air inlet pipe and the second conical air inlet pipe are plugged into and matched with the corresponding charging and discharging holes, the first conical charging and demagnetizing columns and the second conical charging and demagnetizing columns are respectively plugged into and matched with the corresponding charging and demagnetizing holes, and then the corresponding charging and discharging units are activated to inflate the upper rectangular airbag, thereby horizontally unfolding the wound bag body; S2. After the bag is unfolded horizontally, the corresponding inflation and deflation units are activated to inflate the four vertical airbags in the middle and the lower rectangular airbag at the bottom, so that the airbag frame supports the bag to form a rectangular parallelepiped shape. During this process, the controller controls the telescopic mechanism to gradually retract upward to leave space for the bag to be supported; S3, the telescopic mechanism reaches the top of the carriage via the track-traveling trolley, and the rotating mechanism adjusts the direction of the rectangular bag so that the rectangular bag is located directly above the carriage; S4.

The first magnetizing electromagnet and the second electromagnet unit adsorb the bag to the inner surface of the carriage to form a whole. S5. For a bag with a flexible sealing cover, the first screw-nut mechanism and the gantry are initially positioned above the reel. The controller uses the telescopic structure to insert the locking mechanism at the end of the first motor into the jacks at both ends of the reel to stop the rotation and lock it. The free end of the flexible sealing cover is then wound. Simultaneously, the controller controls the first screw-nut mechanism to move toward the other end of the flexible sealing cover. The pull ring pulls the slider through the pull wire to open the zipper, thereby opening the rectangular opening on the upper surface of the bag to facilitate loading. S6. After loading is completed, the controller unfolds the wound flexible sealing cover through the first motor and the reel. At the same time, the controller controls the first screw nut mechanism to move toward the other end of the flexible sealing cover. The pull ring pulls the slider through the pull wire to close the zipper, thereby closing the rectangular opening on the upper surface of the bag body. Then, through the telescopic structure, the locking mechanism at the end of the first motor is pulled out from the jacks at both ends of the reel. The entire material automatic loading and unloading device rises upward through the telescopic unit and detaches from the material transport bag and the carriage.

[0015] The beneficial effects of the present invention are as follows: the automatic loading and unloading device, the material transport bag with an airbag frame, and the material transport bag installation method can obtain, unfold and fix the material transport bag in the vehicle compartment, which is very quick and convenient. For the above-mentioned material transport bag without an airbag frame, the automatic loading and unloading device can still obtain, unfold and fix the material transport bag in the vehicle compartment. When placing the material bag, it is only necessary to lay the material transport bag flat on the material bag placement area. The above-mentioned material transport bag with an airbag frame can also be laid flat on the material bag placement area.

[0016] Furthermore, for the rolled-up material transport bag with an airbag frame placed in the material bag placement area, the upper rectangular airbag can be inflated first to unfold the rolled bag body through the same first electromagnet mechanism located at one longitudinal end of the first rectangular frame or different first electromagnet mechanisms located at one longitudinal end of the first rectangular frame; then the four vertical airbags and the lower rectangular airbag at the bottom are inflated, so that the airbag frame supports the bag body to form a rectangular shape.

[0017] Furthermore, for the bag body with a flexible sealing cover, a horizontal winding structure is set on the gantry, and the horizontal winding structure includes a first motor and a locking mechanism at the end of the first motor. The locking mechanism is inserted into the jacks at both ends of the reel, and then the free end of the flexible sealing cover is wound. At the same time, the first screw and nut mechanism is controlled to move toward the other end of the flexible sealing cover. The pull ring pulls the zipper open through the pull wire to open the rectangular opening on the upper surface of the bag body, which is convenient for loading. After loading is completed, the reverse process is performed to open and close the rectangular opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 3 The method for installing the material transport bag of Example 2 using the material automatic loading and unloading device of Example 1 is as follows: Figure 1-5 As shown, the bag body 30 is a rectangular parallelepiped bag when it is erected, and a sac-shaped frame made of the same material as the bag body and integrally provided, and the following steps are included: S1. At the material transport bag placement position, the telescopic mechanism extends, the first rectangular frame descends, and the two first electromagnet mechanisms at one end of the bottom of the first rectangular frame reach the upper surface of the iron plate corresponding to the wound bag body. The controller starts the first electromagnets of the two first electromagnet mechanisms to magnetize, and the upper connecting plate is attracted to the corresponding iron plate. The first conical air inlet pipe and the second conical air inlet pipe are plugged into and matched with the corresponding charging and discharging holes. The first conical charging and demagnetizing column and the second conical charging and demagnetizing column are respectively plugged into and matched with the corresponding charging and demagnetizing holes. Then, the corresponding charging and discharging unit is started to inflate the upper rectangular airbag, and the wound bag body is horizontally unfolded during the inflation process of the upper rectangular airbag; S2. After the bag is unfolded horizontally, the corresponding inflation and deflation units are activated to inflate the four vertical airbags in the middle and the lower rectangular airbag at the bottom, so that the airbag frame supports the bag to form a rectangular parallelepiped shape. During this process, the controller controls the telescopic mechanism to gradually retract upward to leave space for the bag to be supported; S3, the telescopic mechanism reaches the top of the carriage via the track-traveling trolley, and the rotating mechanism adjusts the direction of the rectangular bag so that the rectangular bag is located directly above the carriage; S4. The rectangular parallelepiped bag is lowered into the carriage through the telescopic mechanism. The controller magnetizes the corresponding first magnetizing electromagnet and magnetizes or energizes the second electromagnet unit through the corresponding magnetizing and demagnetizing holes, the first conical magnetizing and demagnetizing pillars, and the second conical magnetizing and demagnetizing pillars. The first magnetizing electromagnet and the second electromagnet unit adsorb the bag to the inner surface of the carriage to form a whole. S5. For a bag with a flexible sealing cover, the first screw-nut mechanism and the gantry are initially positioned above the reel. The controller uses the telescopic structure to insert the locking mechanism at the end of the first motor into the jacks at both ends of the reel to stop the rotation and lock it. The free end of the flexible sealing cover is then wound. Simultaneously, the controller controls the first screw-nut mechanism to move toward the other end of the flexible sealing cover. The pull ring pulls the slider through the pull wire to open the zipper, thereby opening the rectangular opening on the upper surface of the bag to facilitate loading. S6. After loading is completed, the controller unfolds the wound flexible sealing cover through the first motor and the reel. At the same time, the controller controls the first screw nut mechanism to move toward the other end of the flexible sealing cover. The pull ring pulls the slider through the pull wire to close the zipper, thereby closing the rectangular opening on the upper surface of the bag body. Then, through the telescopic structure, the locking mechanism at the end of the first motor is pulled out from the jacks at both ends of the reel. The entire material automatic loading and unloading device rises upward through the telescopic unit and detaches from the material transport bag and the carriage.

[0035] The beneficial effects of the present invention are as follows: the automatic loading and unloading device, the material transport bag with an airbag frame, and the material transport bag installation method can obtain, unfold and fix the material transport bag in the vehicle compartment, which is very quick and convenient. For the above-mentioned material transport bag without an airbag frame, the automatic loading and unloading device can still obtain, unfold and fix the material transport bag in the vehicle compartment. When placing the material bag, it is only necessary to lay the material transport bag flat on the material bag placement area. The above-mentioned material transport bag with an airbag frame can also be laid flat on the material bag placement area.

[0036] Furthermore, for the rolled-up material transport bag with an airbag frame placed in the material bag placement area, the upper rectangular airbag can be inflated first to unfold the rolled bag body through the same first electromagnet mechanism located at one longitudinal end of the first rectangular frame or different first electromagnet mechanisms located at one longitudinal end of the first rectangular frame; then the four vertical airbags and the lower rectangular airbag at the bottom are inflated, so that the airbag frame supports the bag body to form a rectangular shape.

[0037] Furthermore, for the bag body with a flexible sealing cover, a horizontal winding structure is set on the gantry, and the horizontal winding structure includes a first motor and a locking mechanism at the end of the first motor. The locking mechanism is inserted into the jacks at both ends of the reel, and then the free end of the flexible sealing cover is wound. At the same time, the first screw and nut mechanism is controlled to move toward the other end of the flexible sealing cover. The pull ring pulls the zipper open through the pull wire to open the rectangular opening on the upper surface of the bag body, which is convenient for loading. After loading is completed, the reverse process is performed to open and close the rectangular opening.

[0038] It should be pointed out that the controller and the telescopic mechanism, vertical telescopic push rod, electrical connection unit, charging and discharging unit, each motor, electric push rod, electronic switch of the charging and demagnetizing unit and other controlled devices can be controlled via Bluetooth, GPRS or wire. The power supply can be a battery installed on the track-traveling trolley or it can be AC ​​power. The AC power is often connected to the track with strip-shaped or spring-shaped wires. These are all existing technologies and will not be elaborated here.

One longitudinal end of the flexible sealing cover is fixed on the bag body and the other longitudinal end is a free end. The bottoms of the two lateral sides of the flexible sealing cover and the longitudinal edges of the rectangular opening are connected by a zipper. A reel is fixed on the upper surface of the free end of the flexible sealing cover, and sockets are provided at both ends of the reel. The outer end of the socket has a jack that cooperates with the locking mechanism to lock and prevent rotation. Each zipper has a pull head, and a pull ring is rotatably set at the position opposite to the corresponding zipper on the reel, and the pull head is connected to the corresponding pull ring through a pull line.

10. A method for installing the material transport bag according to claim 9 using the material automatic loading and unloading device according to claim 6, characterized in that The following steps are involved: S1. At the material transport bag placement position, the telescopic mechanism extends, the first rectangular frame descends, and the two first electromagnet mechanisms at one end of the bottom of the first rectangular frame reach the upper surface of the iron plate corresponding to the wound bag body. The controller activates the first electromagnets of the two first electromagnet mechanisms to magnetize, the upper connecting plate is attracted to the corresponding iron plate, the first conical air inlet pipe and the second conical air inlet pipe are plugged into and matched with the corresponding charging and discharging holes, the first conical charging and demagnetizing columns and the second conical charging and demagnetizing columns are respectively plugged into and matched with the corresponding charging and demagnetizing holes, and then the corresponding charging and discharging units are activated to inflate the upper rectangular airbag, thereby horizontally unfolding the wound bag body; S2. After the bag is unfolded horizontally, the corresponding inflation and deflation units are activated to inflate the four vertical airbags in the middle and the lower rectangular airbag at the bottom, so that the airbag frame supports the bag to form a rectangular parallelepiped shape. During this process, the controller controls the telescopic mechanism to gradually retract upward to leave space for the bag to be supported; S3, the telescopic mechanism reaches the top of the carriage via the track-traveling trolley, and the rotating mechanism adjusts the direction of the rectangular bag so that the rectangular bag is located directly above the carriage; S4. The rectangular bag is lowered into the carriage through the telescopic mechanism. The controller magnetizes the corresponding first magnetizing electromagnet and magnetizes or energizes the second electromagnet unit through the corresponding magnetizing and demagnetizing holes, the first conical magnetizing and demagnetizing pillars, and the second conical magnetizing and demagnetizing pillars. The first magnetizing electromagnet and the second electromagnet unit adsorb the bag to the inner surface of the carriage to form a whole. S5. For a bag with a flexible sealing cover, the first screw-nut mechanism and the gantry are initially positioned above the reel. The controller uses the telescopic structure to insert the locking mechanism at the end of the first motor into the jacks at both ends of the reel to stop the rotation and lock it. The free end of the flexible sealing cover is then wound. Simultaneously, the controller controls the first screw-nut mechanism to move toward the other end of the flexible sealing cover. The pull ring pulls the slider through the pull wire to open the zipper, thereby opening the rectangular opening on the upper surface of the bag to facilitate loading. S6. After loading is completed, the controller unfolds the wound flexible sealing cover through the first motor and the reel. At the same time, the controller controls the first screw nut mechanism to move toward the other end of the flexible sealing cover. The pull ring pulls the slider through the pull wire to close the zipper, thereby closing the rectangular opening on the upper surface of the bag body. Then, through the telescopic structure, the locking mechanism at the end of the first motor is pulled out from the jacks at both ends of the reel. The entire material automatic loading and unloading device rises upward through the telescopic unit and detaches from the material transport bag and the carriage.
