[0005] A cream filling production line includes a bottle placement unit, a blow-suction cleaning unit, a filling unit, an inner pad placement unit, a first capping unit, and a second capping unit connected sequentially from front to back. A conveying mechanism for carrying and moving cream bottles is provided between the six units. An inner pad detection device is provided between the inner pad placement unit and the first capping unit. An outer cap detection device is provided after the second capping unit. The movement path of the cream bottles on the conveying mechanism is set as two parallel columns, and 2 to 8 cream bottles are arranged in a straight line as a group for translational conveying.

[0006] An outer cap conveying platform is provided next to the first capping unit. The conveying path of the outer cap is perpendicular to the conveying path of the cream bottle. The conveying mechanism includes an A-type conveying platform and a B-type conveying platform with the two ends of the A-type conveying platform docked at the same height. A line-changing and handling device is provided between the A-type conveying platform and the B-type conveying platform.

[0007] Furthermore, the bottle-positioning unit uses an industrial robot to place the cream bottles on the bottle rack onto the conveying mechanism. The blowing and suction cleaning unit includes a liftable blowing and suction head, which is connected to a positive pressure source and a negative pressure source via a pipe. The filling unit includes a liftable filling head, which is connected to a cream storage box via a pipe. A pump is installed between the cream storage box and the filling head.

[0008] Furthermore, the inner pad placement unit includes an inner pad conveying platform and an industrial robot. The inner pad conveying platform is provided with two parallel inner pad conveying paths, with one inner pad conveying path corresponding to one industrial robot. The inner pad conveying path is perpendicular to the cream bottle conveying path.

[0009] Furthermore, the inner pad detection device includes a liftable inner pad detection column, which is movably mounted on the inner pad detection frame. The inner pad detection frame is equipped with a position sensor, and the detection direction of the position sensor is towards the upper part of the inner pad detection column.

[0010] Furthermore, an outer cover lateral lifting mechanism is provided between the outer cover conveying platform and the first capping unit. The outer cover lateral lifting mechanism includes a fixed frame and a movable frame. The top of the fixed frame is provided with multiple rows of parallel outer cover channels, and the top of the movable frame is provided with multiple rows of parallel U-shaped grooves. A lifting block is provided one-to-one below the notch of the U-shaped groove. The movable frame can move horizontally along the fixed frame. The first capping unit includes a first capping claw that can be lifted and moved horizontally. The horizontal movement range of the first capping claw covers the area above the outer cover lateral lifting mechanism. The second capping unit includes a second capping claw that can be lifted and moved horizontally. The number of the first capping claw and the second capping claw are equal. The first capping claw moves horizontally between the area above the outer cover lateral lifting mechanism and the area above the A-type conveying platform. The second capping unit is located above the A-type conveying platform.

[0011] Furthermore, the outer cover detection device includes a liftable outer cover detection column, which is movably mounted on the outer cover detection frame. A reset elastic element and a sensing mechanism are provided between the outer cover detection column and the outer cover detection frame. The reset elastic element applies a downward pulling force to the outer cover detection column. The sensing mechanism includes a stop fixed to the outer cover detection column and a slotted photoelectric sensor fixed to the outer cover detection frame.

[0012] Furthermore, both the inner pad placement unit and the second capping unit are equipped with a bottle clamping mechanism.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] like Figures 1 to 11 As shown, a cream filling production line includes a bottle placement unit 1, a blow-suction cleaning unit 2, a filling unit 3, an inner pad placement unit 4, a first capping unit 5, and a second capping unit 6 connected sequentially from front to back. A conveying mechanism for carrying and moving the cream bottles is provided between the six units. An inner pad detection device 7 is provided between the inner pad placement unit 4 and the first capping unit 5. An outer cap detection device 8 is provided after the second capping unit 6. The movement path of the cream bottles on the conveying mechanism is set as two parallel columns.

[0035] An outer cap conveying platform 10 is provided beside the first capping unit 5, and the conveying path of the outer cap is perpendicular to the conveying path of the cream bottle. The conveying mechanism includes an A-type conveying platform 11 and a B-type conveying platform 12 with equal height joints at both ends of the A-type conveying platform 11. The A-type conveying platform 11 includes a conveyor belt and bottle molds 11a are arranged at equal intervals on the conveyor belt. Each bottle mold 11a has a recess for accommodating the cream bottle. The cream bottles are placed vertically on the A-type conveying platform 11 and the B-type conveying platform 12. 2 to 8 cream bottles are arranged in a straight line as a group for horizontal conveying, resulting in high production efficiency. A line-changing transport device 13 is provided between the A-type conveying platform 11 and the B-type conveying platform 12. The line-changing transport device 13 transfers each group of cream bottles between the A-type conveying platform 11 and the B-type conveying platform 12. Specifically, there are two line-changing transport devices 13, one before the blowing and suction cleaning unit 2 and the other after the outer cap detection device 8. Figure 9 As shown, the line-changing and conveying device 13 includes a vertically assembled transverse slide 13a and a longitudinal slide 13b. The longitudinal slide 13b drives the transverse slide 13a to rise and fall, and the transverse slide 13a drives the grippers connected below it to move horizontally. Multiple grippers are arranged in a row, and their number corresponds to the number of cream bottles in each group.

[0036] The bottle placement unit 1 uses an industrial robot 9 to place the cream bottles on the bottle rack 1a onto the conveying mechanism. The bottle rack 1a has several holes for placing the cream bottles. The blowing and suction cleaning unit 2 includes a liftable blowing and suction head 2a, which is connected to a positive pressure source and a negative pressure source through a gas pipe. The blowing and suction head 2a is provided with an air blowing port and an air suction port. When the cream bottle moves to the bottom of the blowing and suction cleaning unit 2, the blowing and suction head 2a is lowered to the bottle opening. The positive pressure source blows air through the air blowing port, and the negative pressure source sucks air through the air suction port, thus cleaning the inside of the bottle. The filling unit 3 includes a liftable filling head 3a, which is connected to a cream storage box 3b through a liquid pipe. A pump is provided between the cream storage box 3b and the filling head 3a. When the cream bottle moves to the bottom of the filling unit 3, the filling head 3a is lowered and inserted into the bottle. The pump is activated to fill the bottle with cream from the cream storage box 3b.

[0037] After the cream is filled, an inner pad needs to be placed at the bottle opening. The inner pad placement unit 4 includes an inner pad conveying platform 4a and an industrial robot 9. The inner pad conveying platform 4a is provided with two parallel inner pad conveying paths. One inner pad conveying path corresponds to one industrial robot 9. The inner pad conveying path is perpendicular to the cream bottle conveying path. The industrial robot 9 places the inner pads one-to-one at the bottle opening of the cream bottle.

[0038] After the inner pads are placed, they need to be checked to ensure no pads are missing. See [reference needed]. Figure 5The inner pad detection device 7 includes a liftable inner pad detection column 7a, which is movably mounted on an inner pad detection frame 7b. A position sensor 7c is provided on the inner pad detection frame 7b, and the detection direction of the position sensor 7c is towards the upper part of the inner pad detection column 7a. When the cream bottle moves to the bottom of the inner pad detection device 7, it drives the inner pad detection frame 7b to lower the inner pad detection column 7a. If the inner pad of the lower bottle is successfully placed, the bottom end of the inner pad detection column 7a will abut against the inner pad and cannot continue to descend. Then, the upper part of the inner pad detection column 7a is detected by the position sensor 7c, which inputs a signal to the control system. If the inner pad of the lower bottle is not successfully placed, the position sensor 7c will not detect the inner pad detection column 7a.

[0039] After the inner pad is installed, the outer cover must be installed, in conjunction with... Figure 10 , Figure 11 As shown, an outer cover lateral lifting mechanism 14 is provided between the outer cover conveying platform 10 and the first capping unit 5. The outer cover lateral lifting mechanism 14 includes a fixed frame 14a and a movable frame 14b. The fixed frame 14a remains stationary with the outer cover conveying platform 10. The top of the fixed frame 14a is provided with multiple rows of parallel outer cover channels 14a-1. The top of the movable frame 14b is provided with multiple rows of parallel U-shaped grooves 14b-1. A lifting block 14b-2 is provided one-to-one below the notch of the U-shaped groove 14b-1. The movable frame 14b can move horizontally along the fixed frame 14a. When the conveyor belt on the outer cover conveying platform 10 conveys the outer cover through the outer cover channel 14a-1 into the U-shaped groove 14b-1, the drive... The movable frame 14b moves horizontally to the left or right, and the U-shaped groove 14b-1 moves with the outer cover inside it. Then, the lifting block 14b-2 is driven to move upward to lift the outer cover for the first capping unit 5 to grasp. The first capping unit 5 includes a first capping claw 5a that can be lifted and moved horizontally. The horizontal movement range of the first capping claw 5a covers the area above the outer cover horizontal lifting mechanism 14. The second capping unit 6 includes a second capping claw 6a that can be lifted and moved horizontally. The number of the first capping claw 5a and the second capping claw 6a is equal. The first capping claw 5a moves horizontally between the outer cover horizontal lifting mechanism 14 and the A-type conveyor platform 11. The second capping unit 6 is located above the A-type conveyor platform 11. (Detailed combination...) Figure 1 , Figure 4 As shown, the first capping claw 5a moves above the outer cap horizontal lifting mechanism 14 and then descends to grip the outer cap. After gripping the outer cap, the first capping claw 5a rises and moves above the A-type conveyor platform 11, aligning with the second capping claw 6a in a straight line. Then, the first capping claw 5a, carrying the outer cap, descends to the bottle opening below and performs a preliminary twist. After the initial twist, the A-type conveyor platform 11 continues to move the cream bottle to below the second capping claw 6a. The second capping claw 6a descends, clamps the outer cap, and rotates to perform a second twist until it is tightened.

[0040] After the outer cover is screwed on and installed, it needs to be checked for any missing parts. Specifically, as follows: Figure 6 , Figure 7 As shown, the outer cover detection device 8 includes a liftable outer cover detection column 8a, which is movably mounted on the outer cover detection frame 8b. A reset elastic element 8c and a sensing mechanism 8d are provided between the outer cover detection column 8a and the outer cover detection frame 8b. The reset elastic element 8c applies a downward pulling force to the outer cover detection column 8a. The sensing mechanism 8d includes a stop 8d-1 fixed to the outer cover detection column 8a and a slotted photoelectric sensor 8d-2 fixed to the outer cover detection frame 8b. The method is basically the same as the inner pad detection method. When the cream bottle moves to the bottom of the outer cover detection device 8, the outer cover detection frame 8b is controlled to descend with the outer cover detection column 8a. If the outer cover of the bottle below is successfully installed, the bottom end of the outer cover detection column 8a will abut against the upper surface of the outer cover and cannot continue to descend. Then, the upper stop 8d-1 of the outer cover detection column 8a is detected by the slotted photoelectric sensor 8d-2 and a signal is input to the control system.

[0041] In addition, combined Figure 1 , Figure 2 As shown, both the inner pad placement unit 4 and the second capping unit 6 are equipped with a bottle clamping mechanism 15. The bottle clamping mechanism 15 includes clamping blocks 15a symmetrically arranged on both sides of the A-type conveying platform 11. The near ends of the clamping blocks 15a on both sides are provided with V-shaped grooves. The clamping blocks 15a on both sides are driven to move closer or further apart by the cylinder connected below. When the inner pad placement and capping operations are performed, the opposing clamping blocks 15a move closer to clamp the cream bottle in the middle to ensure the position is aligned and to prevent tipping and rotation.

[0042] The industrial robot 9 used in the above scheme is a SCARA (selective compliant assembly robot arm), whose end effector is connected to a pneumatic suction cup for picking up the bottle body, inner pad and outer cap.
