Description

Technical Field

[0001] The invention relates to the field of cookware manufacturing, and in particular to an automatic production line for round cookware. Background Art

[0002] The method of industrially manufacturing cookware is to use a stretching machine to stretch a circular plate into the shape of a cookware. In the traditional method, workers are required to place the circular plates into the stretching machine one by one, which has low production efficiency and manual operation has safety hazards. Summary of the invention

[0003] In order to improve the automation level of round pan production, the present invention provides a round pan automatic production line.

[0004] An automatic production line for round pots has a conveying direction, comprising a first conveyor belt, an oiling device, a second conveyor belt, a positioning device and a stretching machine arranged in sequence along the conveying direction, and also comprising a material rack, a first material moving mechanism, a second material moving mechanism and a manipulator, wherein the material rack is arranged on the side of the starting end of the first conveyor belt, the first material moving mechanism transfers the round plate between the material rack and the first conveyor belt, the second material moving mechanism transfers the round plate between the second conveyor belt and the stretching machine, and the manipulator is used to transfer the product stretched by the stretching machine.

[0005] The beneficial effect of this embodiment is that the first material transfer mechanism automatically transfers the circular plate from the material rack to the first conveyor belt, and then the first conveyor belt transfers it to the oiling device to apply stretching oil. The circular plate coming out of the oiling device enters the second conveyor belt, and the second conveyor belt transfers the circular plate to the positioning device for positioning, and then the second material transfer mechanism transfers the circular plate to the stretching machine. After the circular plate is stretched into a round pot blank, it is taken out of the stretching machine by the robot. Therefore, the round pot automated production line of this embodiment improves the automation level of round pot blank production.

[0006] In some embodiments, the material rack is arranged on the side of one end of the first conveyor belt, and the material rack includes four vertically arranged columns, and the four columns form a material loading area. A slicing block is rotatably arranged at the top of each column, and the slicing block is arranged along a vertical plane and can rotate in the vertical plane. The lower half of the slicing block below the rotation point is subjected to the force of a spring, so that the upper half of the slicing block above the rotation point is tilted toward the material loading area, and the side edge of the slicing block facing the material loading area is provided with saw teeth. The circular plates are stacked in the material loading area surrounded by the four columns. After the first material moving mechanism absorbs the circular plates, it moves the circular plates upward. The edge of the circular plates will interfere with the slicing blocks at the top of the columns. The circular plates will push the slicing blocks outward, so that the slicing blocks overcome the force of the springs and rotate, and then the circular plates can be taken out. However, when two circular plates are stacked together, the saw teeth on the side edges of the slicing blocks will peel off the lower circular plates from the upper circular plates, thereby realizing the function of material separation.

[0007] In some embodiments, the first conveyor belt includes two rows of conveyor belts arranged in parallel and spaced apart, and a thickness sensor is provided above the space between the two rows of conveyor belts. The thickness sensor is also connected to the PLC control system. When the thickness sensor detects that the thickness of the circular plates on the conveyor belt increases significantly, it indicates that at least two circular plates are superimposed. At this time, the PLC control system controls the equipment to stop and issues an alarm.

[0008] In some embodiments, the oiling device includes a rotatable upper roller, a rotatable lower roller, and an oil distributor disposed above the upper roller, the oil outlet of the oil distributor faces the upper roller, and the upper roller and the lower roller are both provided with felt. This embodiment has the function of automatic oiling, and during the rotation of the upper roller and the lower roller, the oil distributor drips stretching oil onto the felt of the upper roller, and the felts on the two rollers are soaked with the stretching oil, the first conveyor belt conveys the circular plate between the upper roller and the lower roller, and the upper roller and the lower roller convey the circular plate to the second conveyor belt, and the felts on the upper roller and the lower roller evenly apply the stretching oil to the upper and lower surfaces of the circular plate.

[0009] In some embodiments, the oil distributor includes a plurality of oil dripping nozzles and a cross bar, the oil dripping nozzles are fixed on the cross bar, and each oil dripping nozzle is connected to a distributor through an oil guide pipe. After the stretching oil enters the distributor, it is divided into each oil guide pipe and enters the oil dripping nozzle, and drips onto the upper roller through the oil dripping nozzle. The distributor is connected to a refueling pump through a conduit, and the refueling pump supplies oil to the distributor.

[0010] In some embodiments, the positioning device includes a first cylinder and a second cylinder arranged perpendicular to the conveying direction, and the first cylinder and the second cylinder pass through the plane where the upper portion of the second conveyor belt is located. Since the first cylinder, the second cylinder and the circular plate are all circular, when the circular plate is blocked by the first cylinder and the second cylinder, the circular plate can automatically adjust its position to achieve automatic and accurate positioning, thereby ensuring that the circular plate can be accurately placed in the mold of the stretching machine.

[0011] In some embodiments, the first cylinder and the second cylinder are conductors, the first cylinder and the second cylinder are connected to a power supply and an intermediate relay through a wire, the intermediate relay is also electrically connected to a PLC controller, and the PLC controller collects an electrical signal from the intermediate relay. When the circular plate contacts the first cylinder and the second cylinder at the same time, a current is generated in the circuit formed by the power supply, the intermediate relay, the first cylinder, the circular plate and the second cylinder, and when the PLC controller detects the electrical signal from the intermediate relay, the PLC controller controls the second material transfer mechanism to transfer the circular plate to the stretching machine.

[0012] In some embodiments, the first material transfer mechanism includes a first linear module horizontally arranged perpendicular to the conveying direction, a first bracket arranged on the first linear module, a first cylinder vertically arranged on the first bracket, and a first material suction device arranged on the piston rod of the first cylinder. The first linear module drives the first material suction device to reciprocate perpendicular to the conveying direction to suck the circular plate on the material rack and transfer it to the first conveyor belt.

[0013] In some embodiments, the second material transfer mechanism includes a second linear module arranged along the transmission direction, a second bracket arranged on the second linear module, a second cylinder vertically arranged on the second bracket, and a second material suction device arranged on the piston rod of the second cylinder. The second linear module drives the second material suction device to reciprocate along the transmission direction to transfer the circular plate positioned at the end of the second conveyor belt to the stretching machine.

[0014] In some embodiments, a third conveyor belt is further included, the third conveyor belt is arranged close to the stretching machine, and a manipulator transfers the product between the stretching machine and the third conveyor belt. The manipulator transfers the round pot blank obtained by stretching to the third conveyor belt for delivery. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1 , an automatic production line for round pots, having a conveying direction 1, comprising a first conveyor belt 2, an oiling device 3, a second conveyor belt 4, a positioning device 5 and a stretching machine 6 arranged in sequence along the conveying direction 1, and also comprising a material rack 7, a first material moving mechanism 8, a second material moving mechanism 9 and a manipulator 10. The material rack 7 is arranged on the side of the starting end of the first conveyor belt 2, the first material moving mechanism 8 transfers a circular plate 11 between the material rack 7 and the first conveyor belt 2, the second material moving mechanism 9 transfers the circular plate 11 between the second conveyor belt 4 and the stretching machine 6, and the manipulator 10 is used to transfer the product stretched by the stretching machine 6.

[0025] The first material transfer mechanism 8 automatically transfers the circular plate 11 from the material rack 7 to the first transmission belt 2, and then the circular plate 11 is transferred from the first conveyor belt 2 to the oiling device 3 for applying stretching oil. The circular plate 11 coming out of the oiling device 3 enters the second conveyor belt 4, and the second conveyor belt 4 transfers the circular plate 11 to the positioning device 5 for positioning, and then the second material transfer mechanism 9 transfers the circular plate 11 to the stretching machine 6. After the circular plate 11 is stretched into a round pot blank, it is taken out of the stretching machine 6 by the robot 10. Therefore, the round pot automated production line of this embodiment improves the automation level of round pot blank production.

[0026] In certain embodiments, see Figure 2 The material rack 7 is arranged on the side of one end of the first conveyor belt 2. The material rack 7 includes four vertically arranged columns 12, and the four columns 12 surround a material placement area 13. A slice block 14 is rotatably arranged at the top of each column 12. The slice block 14 is arranged along a vertical plane and can rotate in the vertical plane. The lower half 55 of the slice block 14 below the rotation point is subjected to the force of a spring 15, so that the upper half 56 of the slice block 14 above the rotation point is tilted toward the material placement area 13, and the side edge of the slice block 14 facing the material placement area 13 is provided with a sawtooth 16. The relative distance between the four columns 12 can be selected according to the size of the circular plate 11 for manufacturing the pot.

[0027] The circular plates 11 are stacked in a material placement area 13 surrounded by four columns 12. After the first material moving mechanism 8 absorbs the circular plates 11, it moves the circular plates 11 upward. The edge of the circular plates 11 will interfere with the slice blocks 14 at the top of the columns 12. The circular plates 11 will push the slice blocks 14 outward, causing the slice blocks 14 to overcome the force of the springs 15 and rotate, so that the circular plates 11 can be taken out. However, when two circular plates 11 are stacked together, the serrations 16 on the side edges of the slice blocks 14 will peel off the lower circular plate 11 from the upper circular plate 11, thereby realizing the material separation function.

[0028] In some embodiments, a material rack 7 is provided on both sides of the end of the first conveyor belt 2. When the circular plates 11 on one of the material racks 7 are used up, the circular plates 11 on another material rack 7 can be removed, and the device can be continuously operated without stopping.

[0029] In certain embodiments, see Figure 2 The top end of the column 12 is provided with a cutout 17 extending in the axial direction, and the segment block 14 is pivotally connected in the cutout 17 through a pin 18.

[0030] In certain embodiments, see Figure 3 , the spring 15 is in a compressed state, and the spring 15 applies a thrust to the slice block 14 in a direction away from the material placement area 13. One end of the spring 15 abuts against the column 12, and the other end abuts against the lower half 55 of the slice block 14. Further, a first protrusion 19 is provided in the cutout 17 of the column 12, and a second protrusion 20 is provided on the side edge of the slice block 14. One end of the spring 15 is sleeved on the first protrusion 19, and the other end is sleeved on the second protrusion 20. Further, a first limiting portion 57 and a second limiting portion 58 are respectively provided on both sides of the bottom of the cutout 17, and the lower end of the slice block 14 moves between the first limiting portion 57 and the second limiting portion 58. The first protrusion 19 is provided on the first limiting portion 57, and the second limiting portion 58 limits the lower end of the slice block 14.

[0031] In certain embodiments, see Figure 1 and Figure 4 The material rack 7 also includes a material table 22 , and an L-shaped connecting piece 23 is provided at the lower end of the column 12 , and the connecting piece 23 vertically fixes the column 12 on the material table 22 .

In this embodiment, the position of the column 12 can be adjusted, thereby changing the size of the material placement area 13.

[0033] In certain embodiments, see Figure 1 The first conveyor belt 2 includes two rows of conveyor belts arranged in parallel and spaced apart, and a thickness sensor 25 is provided above the space between the two rows of conveyor belts. The thickness sensor 25 is also connected to the PLC controller 26. When the thickness sensor 25 detects that the thickness of the circular plate 11 on the conveyor belt increases significantly, it indicates that at least two circular plates 11 are superimposed. At this time, the PLC controller 26 controls the equipment to stop and issues an alarm.

[0034] In certain embodiments, see Figure 6The oiling device 3 includes a rotatable upper roller 27, a rotatable lower roller 28, and an oil distributor 29 disposed above the upper roller 27. The oil outlet of the oil distributor 29 faces the upper roller 27. The surfaces of the upper roller 27 and the lower roller 28 are both provided with felt 30. This embodiment has the function of automatic oiling. During the rotation of the upper roller 27 and the lower roller 28, the oil distributor 29 drips stretching oil onto the felt 30 of the upper roller 27. The felt 30 on the two rollers are soaked with the stretching oil. The first conveyor belt 2 conveys the circular plate 11 between the upper roller 27 and the lower roller 28. The upper roller 27 and the lower roller 28 transmit the circular plate 11 to the second conveyor belt 4. The felt 30 on the upper roller 27 and the lower roller 28 evenly coats the stretching oil on the upper and lower surfaces of the circular plate 11.
