Description

Technical Field

[0001] The invention belongs to the technical field of filling hose conveying equipment, and in particular relates to an automatic hose loading device of a hose filling and sealing machine. Background Art

[0002] The hose filling and sealing machine is a device used for filling and sealing hose packaging. It is widely used in the cosmetics, medicine, food and other industries, and can achieve accurate filling of pastes, liquids and other materials, and reliably seal the hose after filling to ensure the sealing and quality of the product. The upper tube rack of the hose filling and sealing machine is an important part of the equipment. It is mainly used to place and transport the hose to be filled, and plays a role in positioning and supporting the hose. Through the upper tube rack, the hose can accurately enter the filling and sealing station to ensure the smooth progress of the filling and sealing operations. For example, the patent with the authorization announcement number CN221273700U discloses a kind of upper tube mechanism of the hose filling and sealing machine.

[0003] At present, the upper tube rack of the hose filling and sealing machine has significant drawbacks in the automatic tube loading link. First, the staff needs to manually place the hoses in the material bin of the upper tube rack, and manually arrange these hoses to ensure that they are neatly arranged. This operation not only greatly increases the labor intensity of the staff, but also seriously restricts the convenience and efficiency of the tube loading process of the hose filling and sealing machine; Furthermore, in the process of conveying the hose from the upper tube rack, in order to limit the trajectory of the hose conveying and prevent it from leaving the upper tube position, the activity space of the hose is greatly compressed. In addition, the structural strength of the hose itself is relatively low, and it is very easy to be deformed due to bumps during transportation, and then the hose in the upper tube rack is frequently blocked, which not only reduces the reliability of automatic tube loading, but also has a negative impact on the filling and sealing efficiency of the hose filling and sealing machine, forcing the staff to perform maintenance frequently, further increasing the labor burden. In addition, the deformed hose will interfere with the filling operation of the filling and sealing machine, further affecting the reliability of the use of the hose filling and sealing machine.

[0014] Compared with the existing technology, the advantages of an automatic tube loading device for a tube filling and sealing machine are: 1. Through the electric mechanical arm, CCD visual camera, tube loading mechanism and hose posture adjustment mechanism, when the automatic tube loading device automatically delivers the hose to the hose filling and sealing machine, the PLC controller first drives the motor and the driving mechanism to make the hose posture adjustment mechanism rotate at a constant speed. The speed of this constant rotation matches the tube loading speed of the electric mechanical arm. Then the automatic production line feeds the hoses into the hose posture adjustment mechanism one by one. Finally, the hose will be vertically inserted into the limit hole. Due to the aperture limit of the limit hole, the aperture of the injection end of the hose is too large to enter the limit hole, thereby ensuring that the vertically placed hoses are in a posture with the injection end facing upward. The posture-adjusted hose rotates with the posture adjustment mechanism. Move to the bottom of the CCD vision camera, and then the CCD vision camera cooperates with the PLC controller to make the electric robotic arm move the tube loading mechanism to the top of the hose to be loaded, and then correct the position of the tube loading mechanism through the proximity sensor to ensure that the tube loading mechanism can be reliably inserted into the hose to be loaded. After that, the tube loading mechanism and the electric robotic arm pick up the hose to be loaded and send it to the hose filling and sealing machine to complete the purpose of automatic tube loading. This mechanism enables the tube loading device to have the function of continuous automatic tube loading, and the hose transportation process will not be blocked, so there is no need for emergency maintenance by the staff, which saves time and effort. It can not only improve the convenience and efficiency of automatic tube loading of the hose, but also reduce the labor intensity of the staff.

[0015] 2. Through the air supply mechanism and driving mechanism, the driving mechanism drives the hose posture adjustment mechanism to work. The driving mechanism will inflate the air supply mechanism. After the hollow conical block is inserted into the hose, the extrusion of the hollow conical block can repair the shape of the opening of the hose filling end, so as to avoid the deformation of the filling end due to extrusion or bumping during the transportation of the hose, which affects the filling. At this time, the PLC controller also controls the operation of multiple semiconductor refrigeration plates. The semiconductor refrigeration plates cool the air in the air storage box through metal plates and heat-conducting mesh plates. After the low-temperature air is ejected from the jet inclined hole, it will enter the inside of the hose. Because the low-temperature air can increase the hardness of the hose material, the shape of the hose filling end can be reliably maintained, and the deformation of the hose filling end can be avoided, so as to ensure that the hose can be reliably and quickly filled in the hose filling and sealing machine.

[0016] 3. Through the air guide groove and the expansion rubber membrane, after the hose is picked up by the upper tube mechanism, the air is continuously sent into the picked up hose through the jet inclined hole. Finally, the air is discharged from between the air guide groove and the two expansion rubber membranes, and an air curtain is formed on the top of the hose. This air curtain can prevent impurities from entering the hose, thereby preventing impurities from adhering to the inside of the hose and contaminating the medium poured into the hose, ensuring the safety and reliability of the hose upper tube process. This mechanism enables the upper tube device of the hose filling and sealing machine to prevent impurities from adhering to the inner wall of the hose, thereby improving the reliability of the use of the upper tube device.

The mechanism can automatically adjust the posture of the hose to ensure that the hose can be automatically and reliably put on the hose.

[0025] The electric robotic arm 5, the normally closed valve 69, the one-way air inlet solenoid valve 73, the exhaust solenoid valve 75, the semiconductor refrigeration plate 78, the air outlet solenoid valve 711, the drive motor 12 and the micro vibration motor 15 are all electrically connected to the output end of the PLC controller 13 through wires, the air pressure sensor 76 and the CCD visual camera 4 are electrically connected to the input end of the PLC controller 13 through a data line, and the proximity sensor 63 is electrically connected to the input end of the PLC controller 13 through a data line and a wiring harness plug 64. The above-mentioned power-on devices and electrical connections are all existing technologies and will not be repeated here.

[0026] The operating principle of the present invention is described as follows: when the automatic tube loading device automatically delivers the tube to the tube filling and sealing machine, first, the PLC controller 13 controls the output end of the drive motor 12 to rotate, and the output end of the drive motor 12 causes the tube posture adjustment mechanism 9 to rotate at a constant speed through the drive mechanism 8. The speed of this constant rotation matches the tube loading speed of the electric mechanical arm 5. Then, the automatic production line feeds the tubes into the guide hopper 97 one by one, and then the tubes enter the uniformly rotating tube posture adjustment mechanism 9. Finally, the tube is vertically inserted into the limiting tube hole 95, and due to the aperture limitation of the limiting tube hole 95, the aperture of the filling end of the tube is The hose is too large to enter the limiting tube hole 95, thereby ensuring that the vertically placed hoses are in a posture with the injection end facing upward. The posture-adjusted hoses rotate with the posture adjustment mechanism to the bottom of the CCD visual camera 4, and then the CCD visual camera 4 cooperates with the PLC controller 13 to make the electric mechanical arm 5 move the tube-loading mechanism 6 to the top of the hose to be loaded, and then correct the position of the tube-loading mechanism 6 through the proximity sensor 63 to ensure that the tube-loading mechanism 6 can be reliably inserted into the hose to be loaded. After that, the tube-loading mechanism 6 and the electric mechanical arm 5 send the hose to be loaded to the station of the hose filling and sealing machine to complete the purpose of automatic tube loading; Specifically, the PLC controller 13 controls the drive motor 12 to start, and the drive motor 12 rotates the crankshaft 81. During the rotation of the crankshaft 81, it not only drives the rotating round box 91 to rotate at a uniform speed, but also drives the piston block 79 and the rubber cover 710 to move back and forth through the connecting rod 83. When the piston block 79 and the rubber cover 710 move outward, the one-way intake valve 74 is affected by the negative pressure and draws external air into the air intake box 72. When the piston block 79 and the rubber cover 710 move toward the air storage box 71, the piston block 79 and the rubber cover 710 allow the air in the air intake box 72 to enter the air storage box 71 through the one-way intake solenoid valve 73 that is powered on and stored in the air storage box 71 for standby use. Prepare for the upper tube mechanism 6 to pick up the hose. At this time, the air pressure sensor 76 detects the air pressure of the air storage box 71, and the air pressure value is sent to the PLC controller 13 in the form of an electrical signal. If the air pressure value reaches the warning threshold value preset by the PLC controller 13, the PLC controller 13 controls the one-way air inlet solenoid valve 73 to be powered off and closed, and the air outlet solenoid valve 711 is controlled to be opened, and then the air that needs to be discharged from the air inlet box 72 is discharged through the opened air outlet solenoid valve 711. If the air pressure in the air storage box 71 is lower than the low pressure threshold value preset by the PLC controller 13, the one-way air inlet solenoid valve 73 is controlled to be reopened to replenish air, and the air outlet solenoid valve 711 is closed again; The hose that falls from the guide hopper 97 into the limiting disc rack 94 is inserted into the limiting tube hole 95 to adjust its posture under the guiding effect of the guide protrusion 14 and the high-frequency vibration of the micro-vibration motor 15. The aperture of the limiting tube hole 95 ensures that the posture of the hose is in a vertically upward posture with the injection opening end. At the same time, the hose with adjusted posture moves under the CCD vision camera 4 with the rotating round box 91 rotating at a uniform speed. The CCD vision camera 4 continuously captures the image of the hose and analyzes each frame of the image through the image processing algorithm preset in the CCD vision camera 4. The algorithm recognizes the contour, feature points and other information of the hose to determine whether the hose is in a suitable upper tube position. For example, when the algorithm detects that the injection end opening of the hose is facing a specific direction and the rotation angle reaches a preset value, it is determined that it is a hose that can pick up the upper tube. Once it is identified as When picking up the hose of the upper tube, the CCD visual camera 4 converts its position information into an electrical signal. The electrical signal exists in a specific digital coding form, and records in detail the precise position coordinates of the hose in the hose posture adjustment mechanism 9 and other data. At this time, the PLC controller 13 controls the drive motor 12 to stop rotating for 3 seconds. These 3 seconds can ensure that the electric mechanical arm 5 and the upper tube mechanism 6 can accurately pick up the hose. Then, the signal is sent to the PLC controller 13 through the data line. After receiving the signal from the CCD visual camera 4, the PLC controller 13 analyzes it and extracts the position information of the hose. According to this information, the PLC controller 13 plans the movement path of the electric mechanical arm 5 carrying the upper tube mechanism 6, and drives the motor of the joint of the electric mechanical arm 5 to operate, so that the upper tube mechanism 6 moves closer to the top of the hose to be picked up. When the proximity sensor 63 at the bottom of the upper tube mechanism 6 gradually approaches the top of the hose to be picked up, the proximity sensor 63 continuously detects the distance from the top of the hose. When the distance reaches a preset threshold, the proximity sensor 63 generates a feedback signal and sends it to the PLC controller 13. The PLC controller 13 accurately controls the forward and reverse rotation and speed of the motor in the electric mechanical arm 5 according to the feedback signal, and then fine-tunes the action of the electric mechanical arm 5, adjusts the position and angle of the upper tube mechanism 6, and ensures that the upper tube mechanism 6 can be accurately inserted into the opening of the injection end of the hose to be picked up. At this time, the PLC controller 13 also controls the exhaust solenoid valve 75 and the normally closed valve 69 to be powered on and opened, and the air inside the air storage box 71 is transported to the hollow cover 61 through the soft air pipe 77, and then the air enters the cavity of the hollow conical block 66 through the opened normally closed valve 69, and finally the air passes through the air vent 67 to make the expansion rubber membrane 68 swell, and the swollen expansion rubber membrane 68 fits tightly with the inner wall of the hose, and at the same time, the friction at the fitting position is increased, and it can ensure that the hose can be reliably picked up by the upper tube mechanism 6 and the electric mechanical arm 5, and sent to the station of the hose filling and sealing machine, and then the excess air is sprayed into the hose through the jet inclined hole 65, and finally discharged along the inner wall of the hose and the air guide groove 610. Because the friction between the expansion rubber membrane 68 and the inner wall of the hose is large, and multiple air guide grooves 610 cooperate with exhaust, the impact force of the airflow sprayed from the jet inclined hole 65 will not cause the hose to separate from the upper tube mechanism 6; After the tube-loading mechanism 6 completes the hose limit, the PLC controller 13 controls the electric mechanical arm 5 to move again according to the preset motion trajectory and speed parameters. During the conveying process, the PLC controller 13 continuously monitors the operating status of the motors at the joints of the electric mechanical arm 5, and continuously adjusts the direction and speed of the motors at the joints of the electric mechanical arm 5 to ensure the smoothness and accuracy of the conveying. In this way, the tube-loading mechanism 6 with the hose is safely and accurately conveyed to the station of the hose filling and sealing machine to complete the entire tube-loading conveying process. In this way, the tube-loading machine can be automatically and continuously fed to the hose filling and sealing machine. The entire tube-loading process does not require manual operation, which saves time and effort, and there will be no blockage in the hose conveying process. During the process of automatic tube loading of the hose, the extrusion of the hollow conical block 66 can repair the shape of the opening of the hose filling end, so as to avoid the deformation of the filling end due to extrusion or collision during the transportation of the hose, which affects the filling. At this time, the PLC controller 13 also controls the operation of multiple semiconductor refrigeration sheets 78, which cool the air in the air storage box 71 through the metal plate 17 and the heat-conducting mesh plate 18. After the low-temperature air is ejected from the jet inclined hole 65, it will enter the inside of the hose. Since the low-temperature air can increase the hardness of the hose material, it is ensured that the shape of the hose filling end can be reliably maintained, and the deformation of the hose filling end can be avoided, so as to ensure that the hose can be reliably and quickly filled in the hose filling and sealing machine. Moreover, the automatic hose is continuously purged by low-temperature air to prevent foreign matter from entering the hose, thereby preventing impurities from adhering to the hose and contaminating the medium poured into the hose, thus ensuring the safety and reliability of the hose installation process; In summary, the tube loading device of the hose filling and sealing machine in the present invention not only has the function of continuous automatic tube loading, but also has the function of preventing impurities from adhering to the inner wall of the hose and preventing the filling end of the hose from deforming. The hose transportation process will not be blocked, and there is no need for emergency maintenance by the staff, which saves time and effort. It can not only improve the convenience and efficiency of automatic hose loading, but also reduce the labor intensity of the staff, and ensure that the hose filling and sealing machine will not affect the processing efficiency due to lack of hose or deformation of the hose filling end, thereby improving the reliability of the use of the tube loading device.
