Description

Technical Field

[0001] The present invention relates to the field related to the production of edible oil barrel handles, and in particular to a stacking mechanism for edible oil barrel handles. Background Art

[0002] In order to provide users of oil drums with a stable grip point, and to facilitate operations such as carrying, transferring, and tipping the oil drums during use, and to improve the convenience of using the oil drums, handles are usually set on the oil drums. During the production process of the handles, when the handles are taken out of the mold, they usually need to be stacked to make the stacked handles more neat and standardized, so as to facilitate the subsequent packaging and storage of the handles.

[0003] The existing patent number: CN216970163U discloses a folding device for edible oil drum handles, which includes a base, a monolithic template, a fixed frame, a translation module, a gripping mechanism, and a positioning and retracting module. The fixed frame is fixedly connected to the base, the monolithic template and the positioning and retracting module are both arranged on the surface of the base, the translation module is fixedly mounted on the fixed frame, and the gripping mechanism is mounted on the translation module. The translation module drives the gripping mechanism to move back and forth between the monolithic template and the positioning and retracting module. It can provide a solution for automated production in enterprises and has good application prospects.

[0004] Patent No. CN216970591U discloses a packing and folding assembly for edible oil barrel handles, which provides transitional fixation and stable movement for the edible oil barrel handles from positioning and stacking to packing, thereby facilitating stable production.

[0005] Although the two existing patents have achieved the grasping, moving and stacking of oil drum handles, the following problems still exist: 1. Only one set of suction cups is used for continuous grasping work. Long-term continuous work may cause the pneumatic suction cups to wear out, which may easily affect the service life of the pneumatic suction cups. There is also a lack of redundant design. When a single set of suction cups fails, the entire production line may be shut down, thereby affecting work efficiency; 2. There is a lack of inspection and maintenance of pneumatic suction cups. When the pneumatic suction cups are worn, it is difficult to detect and replace them in time. In addition, the working environment of some pneumatic suction cups is relatively complex, which makes it easy for the pneumatic suction cups to accumulate impurities after long-term use. These impurities may destroy the sealing between the suction cup and the surface of the oil drum handle, which may easily affect the stability of the pneumatic suction cup in grasping the oil drum handle; 3. Only one stacking module for storing oil drum handles is mentioned, which means that the production line may need to be paused to remove the oil drum handles after the storage rack is full, which may affect work efficiency.

[0041] A plurality of pneumatic suction cups 12 are provided on both sides of the rotating plate 6, and the pneumatic suction cups 12 on the front and back sides of the rotating plate 6 are symmetrically arranged one by one;

[0042] like Figures 8 to 11 As shown, in this embodiment, a maintenance mechanism 14 is provided in the suction cup frame 5, and the maintenance mechanism 14 includes a rotary cylinder 145 and a second motor 141 respectively locked and fixed to the upper and lower end surfaces of the suction cup frame 5, a screw rod 142 horizontally rotatably installed in the suction cup frame 5, a mobile frame 143 slidably installed in the suction cup frame 5 and threadedly connected to the screw rod 142, a third motor 1411 fixedly mounted on the left end surface of the mobile frame 143, and a hollow cylinder 144 rotatably installed in the mobile frame 143, and the output shaft of the third motor 1411 is connected to the hollow cylinder 144 via a coupling;

[0043] The output shaft of the second motor 141 is connected to the screw rod 142 through a coupling. An industrial camera 1410 is fixedly embedded in the bottom of the hollow cylinder 144, and three fixed tubes 146 are fixedly installed in the hollow cylinder 144. A group of high-pressure air nozzles 147, a cleaning liquid nozzle 148 and a hot air nozzle 149 are respectively installed on the three fixed tubes 146. The high-pressure air nozzles 147, the cleaning liquid nozzles 148 and the hot air nozzles 149 all pass through the inner side of the hollow cylinder 144. Each group of high-pressure air nozzles 147, the cleaning liquid nozzles 148 and the hot air nozzles 149 correspond one-to-one to a row of pneumatic suction cups 12 in the left and right directions on the rotating plate 6. The three fixed tubes 146 corresponding to the high-pressure air nozzles 147, the cleaning liquid nozzles 148 and the hot air nozzles 149 are respectively connected to the external high-pressure pump equipment, the cleaning liquid output equipment and the hot air output equipment through hoses;

[0044] The bottom output shaft of the rotating cylinder 145 moves through the suction cup frame 5 and is connected to the middle of the top surface of the rotating plate 6;

[0045] The high-pressure air nozzle 147, the cleaning liquid nozzle 148, the hot air nozzle 149, and the industrial camera 1410 are all spaced apart from a set of pneumatic suction cups 12 at the rear end to reduce collisions between the high-pressure air nozzle 147, the cleaning liquid nozzle 148, the hot air nozzle 149, and the industrial camera 1410 and the pneumatic suction cups 12 when the hollow cylinder 144 rotates.

[0046] In this embodiment, two position detection sensors 13 are installed on the support base 8, and a position detection sensor 13 is also installed on the inner top of the suction cup frame 5. The two position detection sensors 13 on the support base 8 are respectively located at the front ends of the two support plates 9. The positions of the support plates 9 can be detected by the two position detection sensors 13 on the support base 8, and the position of the movable frame 143 can be detected by the position detection sensor 13 in the suction cup frame 5, so that the control device can accurately control the first motor 111 and the second motor 141 according to the detected positions of the support plates 9 and the movable frame 143.

[0047] In this embodiment, the position detection sensor 13 is a laser displacement sensor, which has high measurement accuracy and can more accurately detect the positions of the support plate 9 and the movable frame 143;

[0048] In this embodiment, a negative pressure pipe 1412 is fixedly passed through the bottom of the suction cup frame 5. The negative pressure pipe 1412 is offset from the second motor 141, so that the end of the negative pressure pipe 1412 can be connected to an external negative pressure device to suck out the dust and water vapor in the suction cup frame 5.

[0049] In this embodiment, a plurality of strip-shaped through holes are provided on the back of the suction cup frame 5 to facilitate the passage of the air pipe through the strip-shaped through holes on the suction cup frame 5 to connect to the pneumatic suction cup 12, and a plurality of lighting lamps 1413 are installed on the inner rear end of the suction cup frame 5 to facilitate the industrial camera 1410 to better photograph the pneumatic suction cup 12. The hollow cylinder 144 drives the industrial camera 1410 to rotate to face the pneumatic suction cup 12. The industrial camera 1410 captures the subtle features of the suction cup surface, including cracks, wear or deformation, to determine whether the pneumatic suction cup 12 is damaged, so as to facilitate timely replacement of the pneumatic suction cup 12.

[0050] In this embodiment, the first motor 111, the second motor 141, and the third motor 1411 are all servo motors, which are equipped with high-precision encoders inside. They can detect the position, speed, and other information of the motor rotors in real time, thereby facilitating more accurate control and adjustment of the positions of the support plate 9, the movable frame 143, and the hollow cylinder 144.

[0051] like Figure 6As shown, in this embodiment, the second sliding frame 4 and the suction cup frame 5 are connected by a connecting mechanism 7, which includes a telescopic cylinder 71 fixedly mounted on the bottom of the second sliding frame 4, a transmission frame 72 fixedly arranged in the middle of the rear end surface of the suction cup frame 5, and a fixed frame 73 locked and fixed to the telescopic cylinder 71. A rack 74 is coaxially mounted on the output shaft of the telescopic cylinder 71. The transmission frame 72 is rotatably connected to the inner side of the fixed frame 73 via a rotating shaft 76 fixedly mounted at the outer rear end. A gear 75 meshing with the rack 74 is provided on the outside of the rack 74, and the inner ring of the gear 75 is connected to the outer end surface of the rotating shaft 76.

[0052] In this embodiment, a limit stopper 77 is fixedly installed on the inner rear end of the fixing frame 73. The limit stopper 77 is slidably connected to the rear end surface of the rack 74. The limit stopper 77 provides a limit for the rack 74, thereby improving the stability of the rack 74 during movement and reducing the deviation of the rack 74.

[0053] Specifically, the entire mechanism is installed at an appropriate position on the oil drum handle production equipment. When the production mold of the oil drum handle is opened, the first electric guide rail 1 is controlled to drive the first sliding frame 2, the linear module 3a, the second electric guide rail 3b, the suction cup frame 5, and the pneumatic suction cup 12 to move horizontally to the left. At this time, the suction cup frame 5 and the pneumatic suction cup 12 enter the mold. Then, the linear module 3a is controlled to drive the second electric guide rail 3b, the suction cup frame 5, and the pneumatic suction cup 12 to move forward. The pneumatic suction cup 12 moves forward and fits the outer surface of the oil drum handle.

[0054] Then, the air pressure equipment connected to the pneumatic suction cup 12 is controlled to form a negative pressure inside the pneumatic suction cup 12 to suck up the oil drum handle, and the pneumatic suction cup 12 is driven to move backward by the linear module 3a to drive the oil drum handle out of the mold cavity, and the second electric guide rail 3b is controlled to drive the second sliding frame 4, the suction cup 5 and the pneumatic suction cup 12 to move upward, and at the same time, the first electric guide rail 1 is controlled to drive the pneumatic suction cup 12 to move to the right and out of the mold, and then the telescopic cylinder 71 is controlled to drive the rack 74 to retract, the rack 74 drives the gear 75 to rotate, the gear 75 drives the rotating shaft 76 and the transmission frame 72 to rotate, and the transmission frame 72 drives the suction cup frame 5 to rotate from a vertical state to a horizontal state. At this time, the pneumatic suction cup 12 drives the oil drum handle to rotate to the suction At the bottom of the rack 5, the first electric guide rail 1 and the linear module 3a are controlled again until the oil drum handle is moved to align with the positioning and folding module 10, and then the second electric guide rail 3b is controlled to transport the oil drum handle downward to the positioning and folding module 10, and the oil drum handle sucked by the pneumatic suction cup 12 is discharged downward to the positioning and folding module 10 by controlling the air pressure equipment, completing the picking and placing of the oil drum handle. After a batch of oil drum handles are taken out, the telescopic cylinder 71 is controlled again to make the suction cup rack 5 become vertical, so as to facilitate the control of the first electric guide rail 1, the linear module 3a and the second electric guide rail 3b again to guide the pneumatic suction cup 12 into the mold to suck the oil drum handles, so that more oil drum handles can be stacked on the positioning and folding module 10;

[0055] When the pneumatic suction cup 12 needs to be replaced or the pneumatic suction cup 12 after use needs to be maintained, the rotating cylinder 145 can be controlled to drive the rotating plate 6 to rotate 180°. At this time, the positions of the two groups of pneumatic suction cups 12 are swapped, and the pneumatic suction cups 12 that are not used in the suction cup frame 5 are extended from the suction cup frame 5 for use, while the pneumatic suction cups 12 after use enter the suction cup frame 5 for cleaning and maintenance. By starting the external high-pressure pump to generate high air pressure, the high air pressure is ejected outward through the high-pressure air nozzle 147 to blow off the dust on the pneumatic suction cup 12. The hollow cylinder 144 can also be driven to rotate by controlling the third motor 1411, so that the hollow cylinder 144 drives the cleaning liquid nozzle 148 to rotate to face the pneumatic suction cup. At this time, the external cleaning liquid output device introduces the cleaning liquid into the corresponding fixed pipe 146, and through the cleaning liquid The nozzle 148 sprays outward to clean the pneumatic suction cup 12, and the third motor 1411 can be used to drive the hollow cylinder 144 to rotate, so that the hot air nozzle 149 is directly facing the pneumatic suction cup 12, and the hot air sprayed by the hot air nozzle 149 dries the water droplets on the pneumatic suction cup 12, so as to realize multiple cleaning of the pneumatic suction cup 12 according to needs, reduce impurities on the pneumatic suction cup 12, and facilitate the pneumatic suction cup 12 to better absorb the oil barrel handle, and by controlling the second motor 141 to drive the screw rod 142 to rotate, the screw rod 142 drives the movable frame 143 to move in the suction cup frame 5, and the movable frame 143 drives the hollow cylinder 144, the high-pressure air nozzle 147, the cleaning liquid nozzle 148 and the hot air nozzle 149 to move vertically synchronously, so as to more comprehensively clean the impurities on the pneumatic suction cup 12;

[0056] like Figure 7 As shown, in this embodiment, the sliding mechanism 11 includes a first motor 111 fixedly mounted in the support base 8, and two pulleys 112 rotatably mounted in the support base 8. The two pulleys 112 are connected to each other through a transmission belt 113, and the inner ring of any one of the pulleys 112 is connected to the output shaft of the first motor 111. The transmission belt 113 is connected to the support plate 9.

[0057] When enough oil drum handles are stacked on a positioning and gathering module 10, the two first motors 111 can be controlled to drive the corresponding pulley 112 to rotate, and the pulley 112 drives the transmission belt 113 to rotate, and the transmission belt 113 drives the corresponding support plate 9 and the positioning and gathering module 10 to move along the support base 8, so that the positions of the two positioning and gathering modules 10 are swapped, and the positioning and gathering module 10 stacked with oil drum handles moves to the outside for the gripping robot to take the stacked oil drum handles out of the positioning and gathering module 10, while the positioning and gathering module 10 without oil drum handles moves to the inside to provide positioning support for the oil drum handles on the next set of pneumatic suction cups 12.

[0058] The present invention provides a stacking mechanism for edible oil barrel handles. A group of pneumatic suction cups 12 are provided on both the front and back sides of a rotating plate 6, so that the two groups of pneumatic suction cups 12 can be used alternately to reduce the wear caused by the continuous use of one group of pneumatic suction cups 12, which is beneficial to improving the service life of the pneumatic suction cups 12. When one group of pneumatic suction cups 12 is in use, the other group of pneumatic suction cups 12 can be used as a backup. When one group of suction cups needs maintenance or fails, the other group of suction cups can continue to work, thereby ensuring production continuity and improving the work efficiency of grabbing the oil barrel handles.
