[0001] The invention belongs to the technical field of molding machine control, and in particular relates to a control system and method for laminating a feeding rack for agricultural tires. Background Art

[0002] At present, in order to meet the increasing demands for automation, high efficiency, and accuracy in the tire molding process, the molding machine feeding system generally needs to have functions such as automatic guide, deviation correction and centering, fixed length measurement, and automatic material preparation to achieve automatic bonding of rubber materials, especially agricultural tire feeding molding machines. However, in order to meet the above requirements, the feeding rack needs to be matched in its own length, which may cause the length of the feeding rack to exceed the scope of the site, and due to the increase in the length of its own frame, it also increases the difficulty of various links such as back-end processing, transportation, and use. Since the inch span of agricultural tire molding machines is large, the above problems are particularly obvious and need to be solved urgently. In the prior art, the rubber materials are manually bonded and cut on the drum. However, the rubber materials are manually bonded and cut, which is labor-intensive, inefficient, and has poor tire quality stability. In the wider rubber bonding process, it is difficult for one person to meet the work requirements. Summary of the invention

[0017] According to the above aspects and any possible implementation, an implementation is further provided, when the comparison result is that the length of the required rubber material is greater than or equal to the comparison value, the control steps are as follows:

[0018] S1. The rubber material is guided by the guiding device and corrected and centered by the correcting and centering device to the conveyor belt at the rear conveying device. The first material detection device detects the presence of the rubber material on the conveyor belt, and sends the detection information to the remote control device, and the remote control device controls the rear conveying device to continue to convey the rubber material forward to the front conveying device;

[0019] S2. The front conveying device continues to convey the rubber material forward until the third material detection device detects the material head position of the rubber material and the conveying stops;

[0020] S3. After the laminating drum reaches the adhesive laminating station, the remote control device controls the laminating template device to convey the adhesive to the laminating drum. The remote control device calculates the distance that the adhesive needs to be conveyed forward according to the required length of the adhesive and the distance between the third material detection and cutting device.

[0025] M3. After the laminating drum is in place, the laminating of the cut rubber materials is completed.

[0037] The present invention provides a control system for laminating a feeding rack for agricultural tires, the system comprising: a feeding rack, a conveyor belt, a laminating device, a guide device, a cutting device, a material detection device and a laminating template device, wherein:

[0038] The two ends of the conveyor belt are respectively connected to the feeding rack and the laminating device;

[0039] The deflecting device is used to deflect the rubber material for preparing the agricultural tire and convey it to the conveyor belt;

[0040] The cutting device is used to cut the rubber material into required lengths;

[0041] The material detection device is used to detect the conveying position and state of the rubber material;

[0042] The laminating template device is used to laminar the rubber material conveyed by the conveyor belt onto the laminating device.

[0043] Preferably, the system further comprises a deviation correcting and centering device arranged at the end of the feeding rack, and the deviation correcting and centering device is used to adjust the rubber material diverted away so that the rubber material is kept centered during transportation on the conveyor belt.

[0044] Preferably, the system further comprises a front conveying device and a rear conveying device for accelerating the conveying of materials on the conveyor belt.

[0045] Preferably, the system further comprises a feeding roller arranged between the front conveying device and the rear conveying device.

[0046] Preferably, the first material detection device in the material detection device is arranged between the deviation correction and centering device and the rear conveying device; the second material detection device is arranged between the front conveying device and the bonding device; and the third material detection device is arranged between the bonding device and the bonding template device.

[0047] Preferably, the laminating device is a laminating drum.

[0048] Preferably, the system further comprises a remote control device, and the remote control device is connected to the front conveying device, the rear conveying device, the cutting device and the material detection device.

[0049] Specifically, if Figure 1As shown, the agricultural tire feeding rack has multiple conveying lines. The present invention is explained by taking a control system on a conveying line as an example. The conveying line has functions such as automatic unwinding, centering, and length fixing. The control system includes an unwinding device 1, which is arranged at the initial position of the conveying line and is used to unwind the rubber material to the conveyor belt. The rubber material needs to pass through the conveyor belt in the process of being rolled onto the bonding drum, and passes through the rear conveying device, the front conveying device and the bonding template device from the back to the front. The conveyor belt is installed on the roller, and the roller is installed on the feeding rack. The rubber material is sent to the conveyor belt by the unwinding device, and the conveyor belt transports the rubber material to the bonding drum. The deviation correction and centering device 2 is located at the end of the frame of the feeding rack, and adjusts the rubber material that is diverted so that the rubber material is kept in the center of the conveyor belt during transportation; the front conveying device 7 and the rear conveying device 5 both include rollers, a part or a section of the conveyor belt and a power device. The conveyor belt here is a component of the front and rear conveying devices (because the conveyor belt needs to be supported by rollers and the rollers need to rotate to achieve the state of movement), which is used for conveying rubber material; the feeding pressure roller 3 is located at the end of the rear conveyor belt device 5, and is used to increase the friction of the rubber material on the conveyor when the material roll is replaced. The rubber material is in a rolled-up state on the diverting device, so it is called a material roll, and it is in a flat state after the diverting action; the cutting device 6 is located between the front conveying device 7 and the rear conveying device 5 The bonding template device 9 is located at the front end of the conveyor belt, and is composed of a swing frame, a roller and a part of the conveyor belt, and is used for bonding the rubber on the bonding drum 11; the material detection device ①4, the material detection device ②8, and the material detection device ③10 are detection devices on the conveyor line, and are distributed at different positions from the back to the front. The photoelectric switches therein provide the remote control device with information on the position and state of the rubber. The photoelectric switches are used as devices of the material detection devices ①4, ②8, and ③10, and their functions are similar to sensors. The photoelectric switches detect information (the structures of the various detection devices are exactly the same, but they are distributed at different positions). The material detection device ①4 is located on the rear conveyor device 5, and is used to determine whether there is rubber on the conveyor line. The material detection device ②8 is located on the front conveyor device 7, and is used to determine the cutting length of the rubber. The material detection device ③10 is located at the front end of the bonding template device 9, and is used to determine whether the rubber has reached the pre-bonding position.

[0050] As an embodiment disclosed in the present invention, the present invention also provides a control method for an agricultural tire feed rack bonding control system, which is implemented using the control system, including: using the distance between a cutting device and a third material detection device of a material detection device as a comparison value, comparing the required length of the rubber material with the comparison value, and performing different controls according to the comparison result.

[0051] Preferably, when the comparison result shows that the length of the required rubber material is greater than or equal to the comparison value, the control steps are as follows:

[0052] S1. The rubber material is guided by the guiding device and corrected and centered by the correcting and centering device to the conveyor belt at the rear conveying device. The first material detection device detects the presence of the rubber material on the conveyor belt, and sends the detection information to the remote control device, and the remote control device controls the rear conveying device to continue to convey the rubber material forward to the front conveying device;

[0053] S2. The front conveying device continues to convey the rubber material forward until the third material detection device detects the material head position of the rubber material and the conveying stops;

[0054] S3. After the laminating drum reaches the adhesive laminating station, the remote control device controls the laminating template device to convey the adhesive to the laminating drum. The remote control device calculates the distance that the adhesive needs to be conveyed forward according to the required length of the adhesive and the distance between the third material detection and cutting device. After the adhesive is conveyed to the designated position according to the conveying distance, the laminating drum and the front conveying device stop moving at the same time. At this time, the cutting device cuts the adhesive to obtain the adhesive of the required length;

[0055] S4. Continue the bonding action until the adhesive bonding is completed.

[0056] Preferably, when the comparison result shows that the required length of the rubber material is less than the comparison value, the control steps are as follows:

[0057] M1. The rubber material is guided away by the guiding device and corrected and centered by the correcting and centering device to the conveyor belt at the rear conveying device. After the first material detection device detects the presence of rubber material on the conveyor belt, the detection information is sent to the remote control device, and the remote control device controls the rear conveying device to continue to convey the rubber material forward to the front conveying device;

[0058] M2. When the second material detection device detects the beginning of the rubber material, the remote control device calculates the distance the rubber material needs to be conveyed forward according to the required length of the rubber material and the distance between the second material detection device and the cutting device, and stops conveying the rubber material after conveying it to the specified position. The cutting device cuts the rubber material that has stopped conveying, thereby obtaining the rubber material of the specified length. After the cutting is completed, the remote control device controls the front conveying device to continue conveying the cut rubber material forward to the bonding template device. When the third material detection device detects the beginning of the rubber material, the front conveying device stops moving;

[0059] M3. After the laminating drum is in place, the laminating of the cut rubber materials is completed.

[0060] During specific operation, the control method and main process steps of the present invention are as follows: the rubber material is directed away by the directing device 1 and is corrected and centered by the correcting and centering device 2 to the conveyor belt of the rear conveying device 5. After the photoelectric switch of the material detection device ①4 detects the presence of rubber material information on the conveyor belt, the detected information is sent to the remote control device. The device controls the rear conveying device 5 to continue to convey the rubber material forward to the front conveying device 7 according to the detected information. The remote control device controls the cutting device 6 to cut the rubber material according to the required rubber material length and the detection information provided by the material detection device ②8 and the material detection device ③10.

[0061] The control system of the present invention sets the distance from the cutting position of the cutting device 6 to the detection position of the material detection device ③10 as the comparison value of the required rubber material length, and takes this length value as a fixed value. When the required rubber material length is greater than or equal to the comparison value, it is identified as long rubber material; when the required rubber material length is less than the comparison value, it is identified as short rubber material, thereby dividing the rubber material length into two situations: long rubber material and short rubber material, and adopting different control methods for these two situations:

[0062] 2.1) When the rubber material required by the control system is short, the rubber material can be cut before the bonding action to realize the material preparation function of the feeding system. After the bonding drum is in place, bonding can be carried out directly to improve production efficiency. In this case, the material detection device ②8 is used to detect the length of the rubber material, and the detection device ③10 is used to detect the position of the rubber material head. The specific working process is as follows:

[0063] 2.1.1) The rubber material is guided by the guiding device 1 and corrected and centered by the correcting and centering device 2 to the conveyor belt at the rear conveying device 5. After the photoelectric switch of the material detection device ①4 detects the existence of rubber material on the conveyor belt, the remote control device controls the rear conveying device to continue to convey the rubber material forward to the front conveying device 7;

[0064] 2.1.2) The detection position of the material detection device ②8 and the cutting position of the cutting device 6 are of fixed length. When the photoelectric switch of the material detection device ②8 detects the material head, the remote control device calculates the distance the rubber needs to be conveyed forward according to the required length of the rubber and the distance between the detection position of the material detection device ②8 and the cutting position of the cutting device 6, that is, the length of the required rubber minus the distance between the detection position of the material detection device ②8 and the cutting position of the cutting device 6 to obtain the conveying distance. The conveying distance is used as the distance the rubber needs to continue to move forward, and the rubber stops being conveyed at the position after the calculated specified movement distance. The cutting device 6 cuts the rubber that has stopped being conveyed, thereby obtaining the rubber of the specified length. After the cutting is completed, the remote control device controls the front conveying device 7 to continue conveying the rubber forward to the bonding template device 9. When the photoelectric switch of the material detection device ③10 detects the material head, the front conveying device 7 stops moving, thereby realizing the material preparation function of the feeding system.

[0065] 2.1.3) Wait for the laminating drum 11 to be in place to complete the laminating of the rubber material.

[0066] 2.2) When the required rubber material is a long rubber material, it cannot be cut before the bonding action and the material preparation function of the feeding system cannot be realized. In this case, the detection device ③10 is used as the length detection of the rubber material and the position detection of the rubber material head at the same time, and the detection device ②8 does not work in this bonding process. The specific working process is as follows:

[0067] 2.2.1) The rubber material is guided away by the guiding device 1 and corrected and centered by the correcting and centering device 2 to the conveyor belt of the rear conveying device 5. After the photoelectric switch of the material detection device ①4 detects the existence of rubber material on the conveyor belt, the remote control device controls the rear conveying device to continue to convey the rubber material forward to the front conveying device 7 according to the detection information transmitted by the material detection device ①4;

[0068] 2.2.2) The rubber material continues to be conveyed forward until the photoelectric switch of the material detection ③10 detects the material head position and the conveying stops. At this time, the cutting device 6 does not cut the rubber material. At this time, the length of the rubber material on the conveying line is less than the required length of the rubber material, so it cannot be cut;

[0069] 2.2.3) After the laminating drum 11 reaches the adhesive laminating station, the remote control device controls the laminating template device 9 to convey the adhesive to the laminating drum 11. The rotation speed of the laminating drum 11 matches the speed of the conveyor belt to ensure the smooth conveying of the adhesive on the laminating drum and the conveyor belt to avoid the stretching of the adhesive. The detection position of the material detection device ③10 and the cutting position of the cutting device 6 are fixed lengths. The remote control device calculates the distance that the adhesive needs to be conveyed forward according to the required length of the adhesive and the distance between the detection position of the material detection device ③10 and the cutting position of the cutting device 6, that is, the required length of the adhesive minus the distance between the detection position of the material detection device ③10 and the cutting position of the cutting device 6, which is the distance that the adhesive needs to continue to move forward. After being transported to the position of the calculated specified movement distance, the laminating drum 11 and the front conveying device 7 stop moving at the same time. At this time, the cutting device 6 cuts the adhesive to obtain the specified length of the adhesive.

[0070] 2.2.4) Continue the bonding process until the adhesive bonding is completed.

[0071] Therefore, when the layout of the workplace is limited, the control method of the present invention shortens the design length of the feed rack as much as possible while ensuring functions such as automatic guiding, centering, length fixing, and cutting to meet the layout requirements of the conveying line.
