Technical Field
[0001] This application relates to the technical field of intelligent warehousing, and particularly to a handling control method for bagged materials, a handling system, and a control device. Background Art
[0002] In a warehouse for storing bagged materials, a suction cup device that uses suction cups to suck and handle material bags, and a material bag grasping device that uses a manipulator have been widely used in palletizing and loading woven bag materials. However, current handling devices often use only the suction cup device or the grasping device alone to lift and handle goods. The material bag suction device is greatly affected by factors such as the material of the packaging bag. Sometimes, when sucking different material bags, there will be phenomena such as the bags falling off because some bags cannot be adsorbed for a long time. And if only a manipulator is used to grasp the material bags, it will be impossible to grasp the material bags when dealing with some tight stack types. Summary of the Invention
[0003] The present invention aims at the deficiencies in the prior art and provides a handling control method for bagged materials for a goods grasping and transferring device. The goods grasping and transferring device includes a moving mechanism that can move between the goods stack to be transferred and the placing position, and a goods grasping platform installed below the moving mechanism. The goods grasping platform includes a suction cup mechanism that can move up and down relative to the moving mechanism and two support arms arranged on both sides of the suction cup mechanism. There is a bin space between the two support arms for accommodating the transferred material bags, including the following steps:
[0004] S1. Obtain the goods packaging information and the material bag position information of the material bags to be transferred this time sent by the server, and query the corresponding grasping operation mode of the goods grasping platform in the control configuration library according to the goods packaging information;
[0005] S2. If the grasping operation mode is the first operation mode, after controlling the moving mechanism to move and lift to above the target material bag according to the material bag position information, control the suction cup mechanism to extend downward to suck the target material bag. After the suction cup mechanism retracts the goods to the bin space, control the support arms to close below the material bag, and keep the suction cup mechanism continuously adsorb the material bag during the transfer process to the first target position. After the support arms are opened, control the suction cup mechanism to descend to the second target position and then reduce the suction force to release the material bag.
[0006] S3. If the grasping operation mode is the second operation mode, after controlling the moving mechanism to move and lift to above the target material bag according to the material bag position information, control the suction cup mechanism to extend downward to suck the target material bag. After the suction cup mechanism retracts the goods to the bin space, control the support arms to close below the material bag and control the suction cup mechanism to reduce the suction force to release the material bag onto the two support arms. After the support arms lift the material bag and move to the first target position with the moving mechanism, control the two support arms to open and drop the material bag.
[0007] S4. After placing the material bag, control the opened support arms to contract into the storage spaces on both sides, and then drive the cargo grabbing platform to move above the next material bag to be transported.
[0008] Preferably, the cargo packaging information includes the bag body material property and the weight of the material bag.
[0009] Preferably, the step S1 includes:
[0010] S11. Obtain the bag body material property, the weight of the material bag, and the position information of the material bag to be transported this time sent by the server, and obtain the corresponding bag body stretching value and bag body adsorption value in the cargo database according to the bag body material property. The bag body stretching value is configured as the distance that the upper surface of the material bag can be stretched downward after being sucked by the suction cup, and the bag body adsorption value is configured as the pulling force required for the upper surface of the material bag to be separated after being sucked by the suction cup.
[0011] S12. If the bag body adsorption value is lower than the first adsorption preset value or the bag body stretching value is higher than the first stretching preset value, send a task alarm message.
[0012] S13. If the bag body adsorption value is higher than the second adsorption preset value and the bag body stretching value is lower than the first stretching preset value, and the weight of the material bag is within the corresponding weight allowable range of the first adsorption preset value, control the grabbing platform to enter the first operation mode, and the second adsorption preset value is greater than the first adsorption preset value.
[0013] S14. If the bag body adsorption value is higher than the first adsorption preset value but less than the second adsorption preset value, and the bag body stretching value is lower than the first stretching preset value, and the weight of the material bag is within the corresponding weight allowable range of the first adsorption preset value, control the grabbing platform to enter the second operation mode.

After the suction cup mechanism retracts into the chamber space after extracting the cargo, control the support arms to close under the material bag.
[0016] Judge whether the bag body stretching value is greater than the second stretching preset value. If it is greater than the second stretching preset value, control the suction cup mechanism to descend by a buffer set value so that the lower part of the material bag contacts the support arm, and keep the suction cup mechanism continuously adsorb the material bag during transportation to the first target position. After the support arms are opened, control the suction cup mechanism to descend to the second target position and then reduce the suction force to place the material bag. The second stretching preset value is less than the first stretching preset value.
[0017] If the stretching value of the bag body is not greater than the second stretching preset value, the suction cup mechanism is maintained to continuously adsorb the material bag during transportation to the first target position. After the support arm is opened, the suction cup mechanism is controlled to descend to the second target position, and then the suction force is reduced to drop the material bag.
[0018] Preferably, the goods packaging information further includes the bag body size. Two goods grabbing platforms capable of moving relatively away from and close to each other are installed in parallel below the moving mechanism. The goods grabbing platform further includes two receiving structures correspondingly arranged above the two side support arms. The receiving structure has a receiving space capable of accommodating the corresponding side support arm. The step S4 includes:
[0019] Obtain the minimum distance between the two goods grabbing platforms to avoid collision when the support arms are in the open state, and calculate the minimum number of packages of intervals between two material bags to be grabbed in the stack when the support arms of the two goods grabbing platforms are in the open state according to the bag body size;
[0020] Obtain the position information of the next group of material bags to be grabbed by the two goods grabbing platforms. If the number of material bags between the next group of two material bags to be grabbed is less than the minimum number of packages of intervals, after dropping the material bags in this group, control the opened support arms to contract into the two side receiving spaces, and then move the goods grabbing platform above the next group of material bags to be transported.
[0021] Preferably, the step S4 includes:
[0022] After the suction cup mechanism extracts the goods into the silo space, control the goods grabbing platform to move away from the other goods grabbing platform until the distance between the two goods grabbing platforms is greater than the minimum distance, then control the two side support arms to move out of the corresponding receiving spaces and close below the material bag.

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.
[0037] In this embodiment, a method for controlling the handling of bagged materials is disclosed, which is used for a cargo grabbing and transferring device. As shown in the attached Figure 2 figure, the cargo grabbing and transferring device 100 includes a moving mechanism 40 that can move between the stack of goods to be transferred and the conveyor belt or between the area for discharging and palletizing, and a cargo grabbing platform installed below the moving mechanism. The cargo grabbing platform includes a suction cup mechanism 30 that can move up and down relative to the moving mechanism and two support arms 20 arranged on both sides of the suction cup mechanism. There is a storage space 50 between the two support arms for accommodating the transferred material bags. As shown in the attached Figure 1 figure, the method for controlling the handling of bagged materials may include the following content.
[0038] Step S1: Obtain the cargo packaging information and the position information of the material bag to be transferred this time sent by the server, and query the corresponding grabbing operation mode of the cargo grabbing platform in the control configuration library according to the cargo packaging information. Among them, the cargo packaging information includes the bag body material attribute and the weight of the material bag.
[0039] In this embodiment, as shown in the attached Figure 3 figure, step S1 may include the following content.
[0040] Step S11: Obtain the bag body material attribute, the weight of the material bag, and the position information of the material bag to be transferred this time sent by the server, and obtain the corresponding bag body stretching value and bag body adsorption value in the cargo database according to the bag body material attribute. The bag body stretching value is configured as the distance that the upper surface of the material bag can be stretched downward after being sucked by the suction cup, and the bag body adsorption value is configured as the pulling force required for the upper surface of the material bag to be separated after being sucked by the suction cup.
[0041] Specifically, both the bag body stretching value and the bag body adsorption value are obtained by testing with the same or the same type and weight of the material bag filled with materials as the measurement reference. By repeatedly using the suction cup mechanism to test various types and sizes of material bags with different bag body adsorption values and bag body stretching values, critical strip values such as the first stretching preset value, the second stretching preset value, the first adsorption preset value, and the second adsorption preset value used in the following steps can be obtained as the judgment conditions for control actions.
[0042] Step S12, if the bag adsorption value is lower than the first adsorption preset value or the bag stretching value is higher than the first stretching preset value, a task alarm message is issued. When the bag adsorption value is lower than the first adsorption preset value, it will cause the suction cup mechanism to be unable to smoothly adsorb and pick up the material bag, resulting in the failure of the task to transfer goods. When the bag stretching value is higher than the first stretching preset value, even if the suction cup mechanism can adsorb the material bag and lift it smoothly, due to the excessive stretching deformation of the bag body of the material bag under the suction cup mechanism, when the two side support arms are closed, they will collide with the material bag, and it is impossible to support the lower part of the material bag, resulting in the failure of the task.
[0043] Step S13, if the bag adsorption value is higher than the second adsorption preset value and the bag stretching value is lower than the first stretching preset value, and the weight of the material bag is within the corresponding weight allowable range of the first adsorption preset value, the grasping platform is controlled to enter the first operation mode, and the second adsorption preset value is greater than the first adsorption preset value.
[0044] Step S14, if the bag adsorption value is higher than the first adsorption preset value but less than the second adsorption preset value, and the bag stretching value is lower than the first stretching preset value, and the weight of the material bag is within the corresponding weight allowable range of the first adsorption preset value, the grasping platform is controlled to enter the second operation mode. Specifically, when the bag adsorption value is less than the second adsorption preset value, although it is still higher than the first adsorption preset value, that is, the suction cup mechanism can adsorb and pick up the material bag, the adsorption of the material bag is not firm enough, and it may be separated from the suction cup due to the shaking or collision caused by the moving mechanism during the intermediate transfer process and fall off. Therefore, it is necessary to control the grasping platform to enter the second operation mode, that is, after the two support arms are closed, the suction cup mechanism first places the adsorbed material bag on the support arms to prevent the bag body posture from being damaged when the material bag detaches from the suction cup mechanism to the support arms during the subsequent swinging process.
[0045] Step S2, if the grasping operation mode is the first operation mode, after controlling the moving mechanism to move and lift to above the target material bag according to the material bag position information, the suction cup mechanism is controlled to extend downward to suck the target material bag. After the suction cup mechanism retracts the picked-up goods into the bin space, the support arms are controlled to close under the material bag, and the suction cup mechanism is kept adsorbing the material bag continuously during the transfer process to the first target position. After the support arms are opened, the suction cup mechanism is controlled to descend to the second target position and then reduce the suction force to drop the material bag.
[0046] In this embodiment, as shown in the attached Figure 4 figure, Step S2 can specifically include the following steps.
[0047] Step S21, if the grasping operation mode is the first operation mode, after controlling the moving mechanism to move and lift above the target material bag according to the material bag position information, control the suction cup mechanism to extend downward to suck the target material bag. After the suction cup mechanism retracts into the bin space after picking up the goods, control the support arm to close under the material bag.
[0048] Step S22, determine whether the bag stretching value is greater than the second stretching preset value. If it is greater than the second stretching preset value, control the suction cup mechanism to descend by a buffer set value so that the lower part of the material bag contacts the support arm, and keep the suction cup mechanism continuously adsorb the material bag during the transfer process until the first target position. After the support arm is opened, control the suction cup mechanism to descend to the second target position and then reduce the suction force to drop the material bag. The second stretching preset value is less than the first stretching preset value.
[0049] Step S23, if the bag stretching value is not greater than the second stretching preset value, keep the suction cup mechanism continuously adsorb the material bag during the transfer process until the first target position. After the support arm is opened, control the suction cup mechanism to descend to the second target position and then reduce the suction force to drop the material bag.
[0050] Step S3, if the grasping operation mode is the second operation mode, after controlling the moving mechanism to move and lift above the target material bag according to the material bag position information, control the suction cup mechanism to extend downward to suck the target material bag. After the suction cup mechanism retracts into the bin space after picking up the goods, control the support arm to close under the material bag and control the suction cup mechanism to reduce the suction force to release the material bag onto the two support arms. After the support arm holds the material bag and moves to the first target position with the moving mechanism, control the two support arms to open and drop the material bag.
[0051] Step S4, after dropping the material bag, control the opened support arm to contract into the two-side storage spaces, and then drive the goods grasping platform to move above the next material bag to be carried.
[0052] In one embodiment, the goods packaging information further includes the bag size. Two goods grasping platforms that can move relatively away from and close to each other are installed in parallel under the moving mechanism. The goods grasping platform further includes two storage structures correspondingly arranged above the two support arms on both sides. The storage structure has a storage space 60 capable of accommodating the corresponding side support arm. As shown in the appendix Figure 5 shown, this step S4 can specifically include the following content.
[0053] Step S41, obtain the minimum distance between the two goods grasping platforms to avoid collision when the support arms are opened, and calculate the minimum number of bags between two material bags to be grasped in the stack when the support arms of the two goods grasping platforms are opened according to the bag size.
[0054] Step S42: Obtain the position information of the next set of material bags to be grabbed by the two goods grabbing platforms. If the number of material bags between the next two material bags to be grabbed is less than the minimum interval number of packages, after the current set of material bags is placed, control the opened support arms to contract into the two side storage spaces, and then move the goods grabbing platforms above the next set of material bags to be transported.
[0055] In another embodiment, this step S4 may further include the following content.
[0056] Step S43: After the suction cup mechanism extracts the goods into the bin space, control one goods grabbing platform to move away from the other goods grabbing platform until the distance between the two goods grabbing platforms is greater than the minimum distance, then control the two side support arms to move out of the corresponding storage spaces and close below the material bags.
[0057] By setting the support arm storage spaces and folding and contracting the support arms into the storage spaces, the distance between the two goods grabbing platforms can be effectively reduced, so that the two goods grabbing platforms can pick up two material bags that are closer to each other in the stack. At the same time, when the distance between the two material bags to be picked up is far, the support arms do not need to be controlled to rotate and contract into the storage spaces, thereby reducing the energy consumption of the equipment and the wear of the corresponding structure.
[0058] The bagged material handling control method disclosed in this embodiment selects and sends a matching grabbing operation mode to the goods grabbing platforms according to the obtained packaging information and position information of the material bag goods to be transferred in this batch. When the goods grabbing platform is in the first operation mode, after the suction cup mechanism extracts the goods and retracts into the bin space and closes the support arms, control the suction cup mechanism to continuously maintain the suction state of the material bag, so as to ensure that the material bag can be placed and stacked in the best posture. When the goods grabbing platform is in the second operation mode, control the suction cup mechanism to release the material bag after closing below the support arm material bag and then lift the material bag to above the stacking position by the support arm, so as to avoid the problem that some material bags fall onto the support arm in a chaotic posture due to shaking or vibration during the transfer process of the goods grabbing platform, resulting in non-standard subsequent placement postures and subsequent placement postures exceeding the error. By controlling the goods grabbing platform to match different working modes according to different material bags, on the basis of ensuring that the placement posture is as accurate as possible, the problem that some material bags are thrown off and the posture is chaotic during the transfer process due to different package materials can be avoided.
[0059] In this embodiment, as shown in the appendix Figures 6 - 12As shown, a cargo grabbing and transferring device 100 applicable to the bagged material handling control method disclosed in the above embodiments includes a frame 10, a moving mechanism 40, a suction cup mechanism 30, and a support arm 20. Among them, the frame 10 serves as a support component of the cargo grabbing and handling device 100, and is used to support the moving mechanism 40, the suction cup mechanism 30, and the support arm 20. The support arm 20 is disposed on one side of the suction cup mechanism 30 and is installed on the moving mechanism 40. The support arm 20 includes a moving arm frame 21 and a driving member 22. The moving arm frame 21 is swingably connected to the moving mechanism 40. The driving member 22 is connected to the moving arm frame 21 and drives the moving arm frame 21 to swing relative to the material bag to be transported, and supports the bottom of the material bag to be transported adsorbed by the suction cup mechanism 30. Specifically, during the transportation of the material bag to be transported, the suction cup mechanism 30 adsorbs the upper surface of the material bag to be transported under negative pressure, the moving arm frame 21 swings towards the lower surface of the material bag to be transported driven by the driving member 22, and the suction cup mechanism 30 and the moving arm frame 21 act on the material bag to be transported at the same time, so that the bottom of the material bag to be transported is supported, avoiding the material bag to be transported from being in a suspended state, preventing the material bag to be transported from falling from top to bottom, and ensuring the safety of the material bag to be transported during the use of the cargo grabbing and handling device 100.
[0060] In this embodiment, there are two support arms 20. The two support arms 20 are relatively disposed on both sides of the suction cup mechanism 30. The suction cup mechanism 30 is located between the two support arms 20. The distance between the two support arms 20 is greater than the length of the material bag to be transported, so as to facilitate the two support arms 20 to close towards the material bag to be transported, thereby facilitating the two support arms 20 to support the bottom of the material bag to be transported, preventing the material bag to be transported from falling from top to bottom, and ensuring the safety of the material bag to be transported during the use of the cargo grabbing and handling device 100. Among them, one support arm 20 is disposed on the left side of the suction cup mechanism 30, and the other support arm 20 is disposed on the right side of the suction cup mechanism 30, or one support arm 20 is disposed on the front side of the suction cup mechanism 30, and the other support arm 20 is disposed on the rear side of the suction cup mechanism 30. No specific limitation is made here. A connecting member 211 is provided between the driving member 22 and the moving arm frame 21. The connecting member 211 is sleeved on the moving arm frame 21, and the connecting member 211 is connected to the output end of the driving member 22. The output end of the driving member 22 drives the connecting member 211 to swing. At this time, the connecting member 211 is sleeved on the moving arm frame 21, the connecting member 211 is connected to the output end of the driving member 22, and the output end of the driving member 22 drives the connecting member 211 to swing. During the process of the driving member 22 driving the connecting member 211 to swing upward or downward, the connecting member 211 can have a certain degree of freedom with the driving member 22, avoiding hard mechanical contact between the connecting member 211 and the driving member 22, reducing the probability of damage to the connecting member 211, and the moving arm frame 21 swings with the swing of the connecting member 211 to facilitate adjusting the position of the moving arm frame 21 relative to the swing frame 4121.
[0061] In this embodiment, the connecting member 211 is provided with a keyway 211a, and a flat key 212 is connected to the movable boom 21. The flat key 212 is engaged with the keyway 211a, so that the movable boom 21 is fixedly connected to the connecting member 211. At this time, the flat key 212 is engaged with the keyway 211a, and the connection between the connecting member 211 and the movable boom 21 is achieved through the cooperation of the flat key 212 and the keyway 211a, so as to facilitate the fixing of the connecting member 211 to the movable boom 21. Among them, the front end and the rear end of the keyway 211a are in a communicating state, so as to facilitate the engagement of the flat key 212 with the keyway 211a or the disengagement of the flat key 212 from the keyway 211a.
[0062] The movable boom 21 includes a first swinging portion 213 and a first clamping portion 214. The first swinging portion 213 is swingably connected to the moving mechanism 40; the first clamping portion 214 swings along with the swinging of the first swinging portion 213 and is used for clamping the material bag to be transported, so as to adjust the position of the first swinging portion 213 relative to the moving mechanism 40, thereby adjusting the position of the first clamping portion 214 relative to the moving mechanism 40, and further facilitating the first clamping portion 214 to face the material bag to be transported and supporting the bottom of the material bag to be transported.
[0063] An included angle exists between the first swinging portion 213 and the first clamping portion 214. The first clamping portion 214 is swingably connected to the first swinging portion 213, and an elastic member 2141 is connected between the first clamping portion 214 and the first swinging portion 213. At this time, an included angle exists between the first swinging portion 213 and the first clamping portion 214, and the angle of the included angle is greater than 90° and less than 180°.
