Description

Technical Field

[0001] The invention relates to woven bag bagging equipment and a control system, in particular to a woven bag bagging machine and a control system thereof. Background Art

[0002] Woven bags are bags made of plastic materials such as polypropylene (PP) or polyethylene (PE), which are lightweight, durable, and moisture-proof. They are usually made by weaving plastic strips into a mesh structure and are widely used to package and transport various commodities such as fertilizers, grain, cement, etc. Woven bags are widely used in industry and agriculture due to their low cost, high strength, and ease of use.

[0003] The production process of woven bags usually includes a bagging step. An inner bag made of polyethylene (PE) film is placed inside the woven bag. The main reason is that although the woven bag itself is strong and durable, there may be small gaps due to its woven structure. In order to enhance the moisture-proof and waterproof performance, a plastic inner bag is added inside the bag to effectively prevent moisture, dust and other impurities from entering, protecting the quality and safety of the items in the bag. In addition, the inner bag can also prevent the leakage of powdery or fine granular materials, ensuring the cleanliness and safety of the transportation and storage process.

[0004] The existing woven bag bagging machine operates through an automated system, first transporting the woven bag to the designated location, and then preparing the inner bag. The inner bag is accurately placed in the woven bag through a robotic arm or vacuum adsorption. The bagged woven bag is transported to a collection area, ready for bagging or other subsequent processing. The above process is completed under automated control, which improves efficiency and accuracy and reduces manual operations.

[0005] The existing woven bag bagging machines can generally complete 10-20 bagging processes per minute. For some enterprises with large production scales and high output requirements, a single bagging machine cannot meet the needs of their production lines. In order to solve the problem of insufficient output, large-scale production enterprises generally need multiple devices to operate simultaneously to ensure the smooth operation of the production line, which increases the cost of equipment purchase.

[0006] Secondly, the existing bagging machines are generally placed horizontally in the production workshop, and the floor area of ​​the whole machine is about ten square meters. Considering the reserved arrangement space between multiple devices, a bagging machine generally needs to occupy more than twenty square meters or even more than thirty square meters. In the case of purchasing a large number of bagging machines, the floor area is larger.

[0007] Finally, since the control system of the bagging machine uses PLC to realize multiple robot arm feeding, bagging, and conveying links, the failure rate is high and the design cost is increased due to the large number of action links involved in each link.

[0008] Therefore, the present application provides a woven bag bagging machine and its control system, which can achieve the purpose of bagging multiple woven bags through a single bagging process of the bagging machine, thereby reducing the purchase cost and floor space, and improving production efficiency. The control system reduces the difficulty of program design, reduces the failure rate, and reduces the design cost through the coordination of the mechanical structure. Summary of the invention

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0041] Example 1: Woven bag bagging machine

[0042] like Figure 1As shown, a woven bag bagging machine includes an annular conveying plate 1. A connecting frame 2 is arranged in the middle of the annular conveying plate 1. The connecting frame 2 is connected to a motor 3. When the motor 3 is working, it can transmit power to the annular conveying plate 1 through the connecting frame 2, so that the annular conveying plate 1 rotates.

[0043] The woven bags 19 are stacked at the outer circumference of the annular conveying plate 1 , and the inner bags 20 are stacked at the inner circumference of the annular conveying plate 1 .

[0044] In order to achieve the purpose of conveying woven bags and opening the mouth of woven bags. Figure 1 As shown, the present application is provided with columns 4 around the annular conveying plate 1. A support plate 5 is fixedly connected between the columns 4. A plurality of slide grooves 6 are provided on the support plate 5. Slide blocks 7 are slidably connected in the slide grooves 6. The slide blocks 7 are "T" shaped. The slide blocks 7 are slidably arranged in the slide grooves 6. Figure 2 , Figure 3 , Figure 4 As shown, the bottoms of the plurality of sliders 7 are all connected to a woven bag conveying device 8, and the woven bag conveying device 8 includes a driving plate 81. A driving rod 82 is fixedly connected to one side of the driving plate 81 by bolts. A driving wheel 83 is meshed at the bottom of the driving rod 82. A woven bag conveying disc 84 is meshed outside the driving wheel 83, and the bottom of the driving wheel 83 is connected to the woven bag conveying disc 84 with a bearing.

[0045] Among them, a motor 2 9 is fixedly arranged in the middle of the support plate 5. An output shaft 10 is arranged at the bottom of the motor 2 9. The output shaft 10 is fixedly connected to the woven bag conveying disc 84. When the motor 2 9 is working, it can drive the output shaft 10 to rotate, and then drive the woven bag conveying disc 84 to rotate. When the woven bag conveying disc 84 rotates, it can drive the driving wheel 83 to rotate. The driving wheel 83 drives the driving rod 82 to move, and the driving rod 82 can drive the driving plate 81 to slide horizontally in the horizontal direction through the forward and reverse rotation of the motor 2 9.

[0046] Further, a cylinder 11 is extended and fixedly provided at one end of the driving plate 81. A suction device 12 is connected to the bottom of the cylinder 11. The suction device 12 includes a suction rod 121, a suction motor is built in the suction rod 121, and a suction cup 122 is provided at the bottom of the suction rod 121. The suction cup 122 is used to suck and release the woven bag through the inflation and deflation process of the suction motor.

[0047] As mentioned above, when the motor 29 rotates forward, the driving rod 82 drives the driving plate 81 to move horizontally, which can drive the cylinder 11, the suction rod 121 and the suction cup 122 to move horizontally. When the suction cup 122 is above the stacked woven bags, the suction rod 121 is driven downward by the action of the cylinder 11 so that the suction cup 122 contacts one side of the woven bag. After the suction cup 122 absorbs the woven bag, the woven bag is lifted by the suction cup 122. In this process, the upper and lower sides of the woven bag are separated and the bag mouth is opened.

[0048] When the motor 29 is reversed, the driving rod 82 drives the driving plate 81 to retract to the center of the woven bag conveying plate 84, and the suction cup 122 drives the woven bag with the bag opening opened to move to the annular conveying plate 1, and the inner bag bagging process is carried out in this process.

[0049] In order to achieve the purpose of inner bag. Figure 5 As shown, the bottom bearing of the conveying shaft described in the present application is connected to an inner bag conveying disc 13. A plurality of sliding grooves 14 are provided on the inner bag conveying disc 13. A sliding block 15 is provided in the sliding groove 14. The sliding block 15 is "T" shaped. Figure 6 , Figure 7 As shown, the bottom of the plurality of sliding blocks 15 are all fixedly connected to the inner bag conveying device 16. The inner bag conveying device 16 comprises a conveying rod 161. The bottom of the conveying rod 161 is fixedly connected to a conveying plate 162 by bolts. Among them, a conveying wheel 163 is meshed on one side of the conveying rod 161. The conveying wheel 163 is connected to the inner bag conveying disc 13 by a bearing. A gear 164 is meshed on one side of the conveying wheel 163. The output shaft 10 passes through one end of the inner bag conveying disc 13 and is fixedly connected to the gear 164, so that when the output shaft 10 rotates, it can drive the gear 164 to rotate, thereby driving the conveying wheel 163 to rotate. The rotation of the conveying wheel 163 drives the conveying rod 161 to slide laterally in the horizontal direction, thereby driving the conveying plate 162 to move.

[0050] Furthermore, a cylinder 2 17 is provided at the bottom of the conveying plate 162. A support rod 18 is connected to the bottom of the cylinder 2 17 and is laterally provided. An adsorption device 12 having the same structure as above is provided at the end of the support rod 18. When the motor 2 9 rotates, the output shaft 10 drives the gear 164 to rotate. The rotation of the gear 164 drives the conveying wheel 163 to rotate, thereby driving the conveying rod 161 to slide laterally in the horizontal direction. The movement of the conveying rod 161 drives the conveying plate 162 to move, so that the support rod 18 moves.

[0051] As mentioned above, when the suction cup 122 of the adsorption device 12 is placed above the inner bag, the cylinder 17 moves downward, so that the suction cup 122 adsorbs the inner bag and returns to its original position under the action of the cylinder 17. The motor 9 works to drive the inner bag to move outward to the annular conveying plate 1, thereby achieving the purpose of moving the inner bag.

[0052] like Figure 8 As shown, the overall working process is as follows:

[0053] 1. Stack the woven bags as a whole around the outer circle of the annular conveying plate 1, and stack the inner bags as a whole around the inner circle of the annular conveying plate 1, so that the woven bags and the inner bags are under the suction cup 122;

[0054] 2. The suction cup 122 of the woven bag conveying device 8 and the suction cup 122 of the inner bag conveying device 16 respectively adsorb the woven bag and the inner bag, and the mouth of the woven bag is opened;

[0055] 3. The motor 2 9 starts to rotate forward, the output shaft 10 rotates, driving the woven bag conveying plate 84 to rotate clockwise, and the driving wheel 83 rotates clockwise. The driving wheel 83 rotates to drive the driving plate 81 to move toward the center of the woven bag conveying plate 84; the suction cup 122 of the woven bag conveying device 8 drives the woven bag to move onto the annular conveying plate 1;

[0056] 4. Simultaneously with step 3, the output shaft 10 rotates, driving the gear 164 to rotate clockwise. The conveying wheel 163 rotates counterclockwise, thereby driving the conveying plate 162 to move outward, and the suction cup 122 of the inner bag conveying device 16 drives the inner bag to move from the inside to the outside.

[0057] 5. The woven bag with the bag opening moved inward corresponds to the inner bag moving outward, and the inner bag enters the woven bag. At this time, the support rod 18 on the inner bag further opens the bag opening to facilitate the inner bag to enter the woven bag. Finally, the inner bag reaches the end of the woven bag, and the adsorption device 12 releases the woven bag and the inner bag;

[0058] 6. The motor 2 9 is reversed to reset the woven bag conveying device 8 and the inner bag conveying device 16. By rotating the motor 2 9 forward and reverse once, multiple woven bags and inner bags can be fitted together, that is, multiple bagging processes can be achieved at one time;

[0059] 7. Motor 1 3 is started, so that the annular conveyor plate 1 moves step by step, so that the woven bag and the inner bag that have been put on are separated; repeat step 16 to perform a new bagging process.

[0060] As mentioned above, the woven bag that has been put on can be detached from the annular conveying plate 1 through other recovery devices, such as a swing rod and an air jet process. This is not the core content of the present application and will not be described here.

[0061] Through the above-mentioned bagging process of the woven bags and the inner bags which are close to each other and put on each other, the bagging process of multiple woven bags can be realized by one forward and reverse action of the motor 2 9. Compared with the prior art that realizes the bagging process of one woven bag per action, the above-mentioned process improves the production efficiency, and there is no need to purchase multiple bagging machines, thereby reducing the purchase cost. The woven bag conveying device 8 and the inner bag conveying device 16 are arranged vertically up and down, saving floor space.

[0062] Example 2: Control system of woven bag bagging machine

[0063] In order to reduce the failure rate of programming through the PLC system and reduce the design cost. Fig. 9As shown, the present application also provides a control system for a woven bag bagging machine, including a main circuit and a control circuit. The main circuit includes three live wires L1, L2, and L3, and the voltage between every two live wires is the line voltage, and the voltage value is 380V. A low-voltage power supply can also be used, and it can be replaced accordingly according to actual needs.

[0064] Among them, L1, L2, and L3 are connected to a main circuit breaker QF, which is used to control the disconnection and opening of the main power supply.

[0065] Three AC contactors KM1, KM2 and KM3 are electrically connected below the main circuit breaker QF and are connected in parallel.

[0066] Among them, KM1 and KM2 are connected in reverse, KM1 and KM2 are connected to motor 2 9 (hereinafter referred to as M1), and KM3 is connected to motor 1 3 (hereinafter referred to as M2). Among them, M1 can realize the forward and reverse functions by connecting KM1 and KM2 respectively, and M2 can realize the forward function through KM3.

[0067] The control loop includes seven branches, named branch 1, branch 2, branch 3, ... branch 7.

[0068] Branch 1 includes a normally closed button switch SB1 and a normally open button switch SB2. Branch 1 also includes a switch and an intermediate relay for controlling the opening and closing of the switch, collectively referred to as KA1 below. Among them, SB2 is provided with a switch KA1 in parallel. KA1 and SB2 are connected to the intermediate relay KA1. In the above process, SB2 can be set as a signal receiver of the sensor, which starts working when the woven bag and the inner bag are adsorbed by the suction cup 122, or it can be a manual normally closed switch. When SB2 is connected, the intermediate relay KA1 works, so that the switch KA1 is turned on, and a normally closed conduction circuit is obtained, which is still in the on state when SB2 is disconnected.

[0069] Branch 2 includes the same switch KA1 as above, and a time switch KT3 connected to switch KA1, KT3 is in a normally closed state. Branch 2 also includes a power-on delay time relay KT1 connected to KT3. In the above branch 1, the intermediate relay KA1 turns on each switch KA1, so that branch 2 is turned on. When branch 2 is turned on, KT1 is turned on and starts timing, and the specific time is determined according to the moving distance of the woven bag.

[0070] Branch 4 includes switch KA1, normally closed time switch KT1 and intermediate relay KM1. KA1 is turned on, making branch 4 turned on. Intermediate relay KM1 works, making AC contactor KM1 in the main circuit closed, motor 29 (M1) starts working, M1 rotates forward to drive the woven bag to move from outside to inside, and at the same time makes the inner bag move from inside to outside.

[0071] Branch 3 includes time switch KT1 and time relay KT2. Time switch KT1 is controlled by time relay KT2. When M1 rotates forward until the timing of time counter KT1 ends, the states of each time switch KT1 are swapped. Time switch KT1 in branch 3 is closed, time counter KT2 is turned on and starts timing. KT1 in branch 4 is disconnected, and KM1 is disconnected.

[0072] Branch 5 includes a normally open time switch KT1, a normally closed time switch KT2, and an intermediate relay KM2. When the timing of the above-mentioned time relay KT1 ends, the time switch KT1 in branch 5 is closed, branch 5 is turned on, KM2 starts to work, and M1 is reversed. This state is the process of resetting after the bagging is completed. When the timing of the time relay KT2 ends, KT2 in branch 5 is disconnected, branch 5 is disconnected, and KM2 is powered off.

[0073] Branch 7 includes a normally open time switch KT2, a normally closed time switch KT3 and a time relay KT3. When the timing of the time relay KT2 ends, the normally open time switch KT2 is closed, and the time relay KT3 is turned on to start timing.

[0074] Branch 6 includes a normally open time switch KT2, a normally closed time switch KT3, and an intermediate relay KM3. When KM2 is powered off, the normally open time switch KT2 is closed, branch 6 is turned on, and KM3 is powered. KM3 closes the AC contactor KM3, and the motor 1 (M2) starts to work, causing the annular conveyor plate 1 to rotate and output the woven bags that have been bagged.

[0075] When the timing of time relay KT3 ends, the time switch KT3 in branch 6 is disconnected, KM3 is powered off and shut down, at this time, KT3 in branch 2 is disconnected, so that the time calculator KT1 is disconnected, so that each KT1 is reset, the time relay KT2 in branch 3 is disconnected, the time switch KT2 in branch 7 is disconnected, and the time relay KT3 is disconnected. At this time, KT3 in branch 2 is reset due to the disconnection of time relay KT3, so that KT1 is turned on again. The above steps are repeated cyclically, so that the forward rotation of motor 1 3 (M2) and the forward and reverse rotation of motor 2 9 (M1) are cyclically performed.

[0076] In practical applications, the woven bag and the inner bag can be re-adsorbed during the movement of the annular conveyor plate 1, that is, during the operation of M2. After M2 stops working, it can resume working at M1 to carry out a new bagging process.

[0077] In addition, the thermal relay and thermal switches FR1 and FR2 are provided for safety control, which disconnect the entire circuit when the whole machine is overheated to prevent M1 and M2 from burning out.

[0078] Through the above settings, the above control system is integrated into the PLC component and used as a module, which can reduce the failure rate of the overall program design, reduce the design cost and reduce the connection problems in the bagging process, thereby achieving higher program operation accuracy.

[0079] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
