Description

Technical Field

[0001] This invention relates to the field of bottle neck processing equipment technology, and in particular to a bottle neck feeding device and its feeding method. Background Technology

[0002] Bottle necks are generally circular in shape, and after cutting, they require further processing and inspection. To automate this process, existing technologies utilize automated equipment for feeding, moving, and processing bottle necks. While this type of equipment achieves automation, it employs a hopper and conveyor belt structure to deliver the cut bottle necks to various processing positions. This feeding method is suitable for bottle necks with identical structures on both sides, without front-back or structural differences. However, for bottle necks with different structures on both sides, front-back or structural differences, the front-back of the bottle neck needs to be inspected before being fed to the processing position. This requires automatic front-back detection by the feeding mechanism. However, existing technologies cannot automatically distinguish the front and back of the bottle necks during feeding, resulting in irregular and disordered feeding, which affects the efficiency and quality of subsequent automated processing. In addition, after the pre-processing such as bottle neck cutting, there will be defective parts, shot blasting balls left over from the previous process, iron filings, etc. Since the current feeding process does not have the corresponding processing function, two situations will occur: one is that they will flow to the subsequent process, affecting the continuity and quality of the subsequent processing and the difficulty of subsequent inspection; the other is that in order to ensure the quality of the bottle neck, it is necessary to pre-process the bottle neck before feeding, which will increase the processing time of the pre-processing and affect the continuity of the feeding process after the bottle neck cutting process, thus affecting the efficiency of the subsequent feeding process. Summary of the Invention

[0003] The purpose of this invention is to provide a bottle mouth feeding device and its feeding method, which can remove iron filings, defective parts, etc. when the bottle mouth is vertically rolled for feeding, and can also perform front and back detection, while ensuring the continuous and smooth feeding of the whole, thereby effectively improving the quality and efficiency of subsequent processing.

[0010] More preferably, the rotary clamping assembly includes a base, on which a stepper motor is mounted. The output shaft of the stepper motor is connected to a turntable. The output end of the turntable is provided with a left clamping member. The left clamping member is movably connected to a right clamping member via an elastic connector. The elastic connector includes a sliding rod disposed between the left and right clamping members. A spring is sleeved on the sliding rod. The front ends of the left and right clamping members are fitted with a feeding assembly. The output assembly is located below the feeding assembly. A rotating discharge hole is opened on the side of the feeding assembly, corresponding to the output end of the output assembly. The left clamping member is integrally formed on the front end of the turntable. A fixing seat is provided on the outer cover of the turntable. An insertion hole is opened on the fixing seat. A cutting tool connected to the detection fixing table is provided above the fixing seat.

[0011] More preferably, the feeding assembly includes a feeding seat with a feeding groove in the middle. The front ends of the left clamping member and the right clamping member are located in the feeding groove. A support block is provided at the lower end of the feeding groove. The upper end of the support block is provided with a feeding guide block that corresponds to the left clamping member and the right clamping member respectively.

[0013] More preferably, the output component includes a discharge rack located on one side of the feeding seat, a discharge cylinder inside the discharge rack, an output slot at the upper end of the discharge rack corresponding to the rotating discharge hole on one side of the feeding seat, a forward / reverse and height detection platform on the output slot, a conveying slide rail on the other side of the feeding seat, a conveying slider connected to the piston rod of the discharge cylinder on the conveying slide rail, a push rod on one side of the conveying slider corresponding to the rotating discharge hole on the other side of the feeding seat, and a defective product identification component located outside the discharge rack. The defective product identification component includes a support frame, an identification cylinder on the support frame, a identification plate connected to the piston rod of the identification cylinder corresponding to the forward / reverse and height detection platform on one side, and a defective product trough on the frame corresponding to the output end of the identification plate.

[0014] A bottle neck feeding method includes the following steps:

[0015] a. Pushing: The pusher cylinder pushes the bottom plate, front main plate, back main plate, left inclined plate and right inclined plate to move from bottom to top in the hopper. Without a power source, multiple bottle mouths enter the discharge chute and roll along the inclined discharge chute to the feed chute. When the bottle mouths roll in the discharge chute, iron pins, broken parts and other debris can be discharged from the gap between the front main plate and the back main plate through the discharge hole along the discharge chute.

[0016] b. Front and back detection: When the bottle mouth step faces left, the left detection plate contacts the bottle mouth first, transmitting a low-pressure signal to the right signal transmission bolt. The right signal transmission bolt then transmits the signal to the control unit, which controls the detection cylinder to drive the left and right detection plates downward to detect the front and back of the bottle mouth. When the bottle mouth step faces right, the left detection plate contacts the bottle mouth first, transmitting a low-pressure signal to the left signal transmission bolt. The left signal transmission bolt then transmits the signal to the control unit, which controls the detection cylinder to drive the left and right detection plates downward to detect the front and back of the bottle mouth.

[0017] c. Clamping and Rotation: When checking the front and back of the bottle opening, the left and right detection plates move down, and the insert blade also moves down. This causes the insert blade to control the right clamping part to move with the left clamping part under the action of the elastic connector, thus clamping the bottle opening. If the stepped surface of the bottle opening is on the left, the stepper motor drives the turntable to rotate 90 degrees counterclockwise, so that the bottle opening is flat and the stepped surface is facing up. If the stepped surface of the bottle opening is on the right, the stepper motor drives the turntable to rotate 90 degrees clockwise. After the clockwise or counterclockwise rotation is completed, the bottle opening enters the output component from the left.

[0018] d. Sorting and discharging: After the bottle mouth is laid flat, the discharge cylinder drives the conveying slider to move, while the push rod pushes the bottle mouth from the feed seat to the output slot. The front and back and height detection table sorts the bottle mouth to identify good and bad products. When a bad product cannot be pushed out of the front and back and height detection table, the sorting cylinder drives the sorting plate to push the bottle mouth of the bad product into the bad product trough.

[0019] The invention offers the following advantages: It includes a frame, with a feeding device located in the middle of the frame. The output end of the feeding device is equipped with a detection device, and the output end of the detection device is fitted with a discharge device. A control box is mounted on the frame. The feeding device includes a hopper with a pushing assembly passing through it. The detection device includes a rotary clamping assembly with a detection component positioned above it. The discharge device includes an output component positioned below the corresponding detection component, with a defective product identification component mounted on the output component. During feeding, the control box controls the pushing assembly. The bottle necks in the hopper are pushed to the top, then rolled to the detection component for front and back inspection. The bottle necks are then clamped by the rotating clamping component and rotated. After that, the bottle necks are sent out from the detection component by the output component. At the same time, defective bottle necks are identified and sent out by the defective product identification component, while good bottle necks are sent to the next process through the output component. In this way, when the circular bottle necks are vertically rolled for feeding, iron filings, defective parts, etc. can be removed, front and back inspection can be performed, and the continuous and smooth feeding of the whole process can be ensured, thereby effectively improving the quality and efficiency of subsequent processing.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-7 As shown, a bottle neck feeding device includes a frame 1. A feeding device is located in the middle of the frame 1. A detection device is located at the output end of the feeding device, and a discharging device is located at the output end of the detection device. A control box 2 is mounted on the frame 1. The feeding device includes a hopper 3, with a pushing assembly 4 passing through it. The detection device includes a rotary clamping assembly 5, with a detection assembly 6 positioned above the rotary clamping assembly 5. The discharging device includes an output assembly 7 located below the detection assembly 6, with a defective product identification assembly 8 positioned on the output assembly 7. During feeding, the control box 2 controls... The feeding assembly 4 pushes the bottle neck in the hopper 3 to the upper part, and then the bottle neck rolls to the detection assembly 6 for front and back detection. Then, the bottle neck is clamped by the rotating clamping assembly 5 and rotated. After that, the bottle neck is sent out from the detection assembly 6 through the output assembly 7. At the same time, the bottle neck of defective products is identified and sent out by the defective product identification assembly 8, and the bottle neck of good products continues to be sent to the next process through the output assembly 7. In this way, when the circular bottle neck is vertically rolled for feeding, iron pins, defective parts, etc. can be removed, front and back detection can be performed, and the continuous and smooth feeding of the whole process can be guaranteed, thereby effectively improving the quality and efficiency of subsequent processing.

[0029] like Figure 2 As shown in this embodiment, two sets of symmetrically arranged pushing components 4 are installed inside the hopper 3. The discharge ends of the two sets of pushing components 4 are provided with sliding grooves 9 on both sides of the hopper 3. The output ends of the two sliding grooves 9 are respectively provided with detection devices and discharge devices. In use, the pushing components 4 enter the detection devices and discharge devices on both sides of the frame 1 from both sides of the hopper 3 through the sliding grooves 9, which can further increase the overall feeding efficiency.

[0030] like Figure 2As shown, in this embodiment, the pushing assembly 4 includes a front main board 41 and a back main board 42. An inclined discharge trough 43 is formed between the front main board 41 and the back main board 42. A left inclined plate 44 and a right inclined plate 45 are provided between the front main board 41 and the back main board 42. A discharge trough 46 is formed between the left inclined plate 44 and the right inclined plate 45. A bottom plate 412 is provided at the bottom end of the front main board 41 and the back main board 42. A discharge hole 47 communicating with the bottom end of the discharge trough 46 is opened on the bottom plate. A waste discharge port 48 is provided below the discharge hole 47. A pushing cylinder 411 is provided at the bottom end of the bottom plate 412. Discharge ports 49 communicating with the discharge trough 43 are opened on both sides of the hopper 3. The sliding trough 9... The end is set inside the discharge port 49 and is inclined to correspond to the discharge trough 43. During operation, the bottle mouth is first placed in the hopper 3. Then, the bottom plate, the front main plate 41, the back main plate 42, the left inclined plate 44 and the right inclined plate 45 are pushed from bottom to top in the hopper 3 by the pushing cylinder 411. When the pushing rises, it can automatically guide the direction of the bottle mouth. At the same time, multiple bottle mouths enter the discharge trough 43 and are rolled out along the inclined discharge trough 43. When the bottle mouth rolls in the discharge trough 43, it is easy for iron pins, defective parts, etc. to be discharged from the gap between the front main plate 41 and the back main plate 42 along the discharge trough 46 and through the discharge hole 47 to the waste discharge port 48. In this way, iron pins, defective parts, etc. can be removed at the same time as the bottle mouth is fed, thereby ensuring the continuity of feeding.

[0031] like Figure 2 As shown, in this embodiment, the discharge trough 43 is located at the top of the front main plate 41. The discharge trough 43 is inclined at a 15° angle to the horizontal plane of the bottom plate, so that the bottle mouth can roll in a specified direction by its own weight when feeding. Under the premise of no power source, the bottle mouth of the workpiece can rotate in a specified direction. The distance between the front main plate 41 and the back main plate 42 is 10mm, so that the gravity direction is uniform when the bottle mouth rolls and does not fall. The top of the back main plate 42 is provided with an arc-shaped cut 410, which is flush with the bottom of the discharge trough 43. The arc-shaped cut 410 changes the surface contact when the bottle mouth rolls during feeding to line contact, reducing the frictional resistance when the workpiece rolls.

[0032] like Figure 3 , 4As shown, in this embodiment, the detection component 6 includes a main board 61, an insulating base plate 62 at the bottom of the main board 61, a support plate 63 at the rear end of the main board 61, a detection slide rail on the main board 61, a detection groove on the detection fixing platform 65 that slidably connects with the detection slide rail, a detection cylinder 64 on the main board 61, the lower end of the piston rod of the detection cylinder 64 connected to the detection fixing platform 65, a left detection plate 66 and a right detection plate 67 that cooperate in detection on the detection fixing platform 65, a rotary clamping component 5 located below the left detection plate 66 and the right detection plate 67, a bolt insulating fixing plate 68 connecting the lower end of the piston rod of the cylinder to the detection fixing platform 65, and a left signal transmission bolt 69 and a right signal transmission bolt 60 respectively connected to the left detection plate 66 and the right detection plate 67. 10. The lower inner side of the left detection plate 66 has an inclined surface 611 and a vertical bending surface 612 from top to bottom. The bottom end of the right detection plate 67 has a V-shaped groove 613. During detection, when the left detection plate 66 and the right detection plate 67 cooperate to detect that the bottle mouth step faces left, the left detection plate 66 contacts the bottle mouth first and transmits a low-pressure signal to the right signal transmission bolt 610 through the control box 2. The right signal transmission bolt 610 transmits the signal to the control unit, which controls the cylinder to drive the left detection plate 66 and the right detection plate 67 to move down to detect the front and back of the bottle mouth. When the bottle mouth step faces right, the left detection plate 66 contacts the bottle mouth first and transmits a low-pressure signal to the left signal transmission bolt 69. The left signal transmission bolt 69 transmits the signal to the control unit, which controls the cylinder to drive the left detection plate 66 and the right detection plate 67 to move down to detect the front and back of the bottle mouth.

[0033] like Figure 5 , 6As shown, in this embodiment, the rotary clamping assembly 5 includes a base 51, on which a stepper motor 52 is mounted. The output shaft of the stepper motor 52 is connected to a turntable 53. The output end of the turntable 53 is provided with a left clamping member 54. The left clamping member 54 is movably connected to a right clamping member 55 via an elastic connector. The elastic connector includes a sliding rod 56 disposed between the left clamping member 54 and the right clamping member 55. A spring 57 is sleeved on the sliding rod 56. The front ends of the left clamping member 54 and the right clamping member 55 are fitted with a feeding assembly. The output assembly 7 is located below the feeding assembly. The side of the feeding assembly has a rotating discharge hole 58 corresponding to the output end of the output assembly 7. The left clamping member 54 is integrally formed on the front end of the turntable 53. The turntable 53 is covered with a fixing seat 59. The fixing seat 59 has an insertion hole 510. Above the fixing seat 59 is a detection fixing platform. The insert 511 connected to 65 is a feeding assembly including a feeding seat 512. A feeding groove 513 is formed in the middle of the feeding seat 512. The front ends of the left clamping member 54 and the right clamping member 55 are located within the feeding groove 513. A support block 514 is provided at the lower end of the feeding groove 513. Feed guide blocks 515, corresponding to the left clamping member 54 and the right clamping member 55 respectively, are provided at the upper end of the support block 514. A rotating discharge hole 58 is formed in the feeding seat. Both sides of 512 are connected to the feed chute 513. When the bottle mouth is inspected for both sides, the left inspection plate 66 and the right inspection plate 67 move down, and the inserter 511 also moves down. The inserter 511 controls the right clamping member 55 to move with the left clamping member 54 under the action of the elastic connector, and clamps the bottle mouth in cooperation. Then, the stepper motor 52 drives the turntable 53 to rotate 90 degrees clockwise or counterclockwise, so that the bottle mouth is laid flat. Finally, the bottle mouth enters the output component 7 from the left.

[0034] like Figure 5 , 6 As shown, the elastic connector includes a sliding rod 56 disposed between the left clamping member 54 and the right clamping member 55. A spring 57 is sleeved on the sliding rod 56. When the insert 511 moves downward, the inclined surface of the insert 511 transmits force to the spring 57 through the arc surface of the right clamping member 55, causing the spring 57 to compress to the left and clamp the bottle mouth. When the insert 511 moves upward, the spring 57 uses tension to reset the right clamping member 55.

[0035] like Figure 5 , 6As shown in this embodiment, the front ends of the left clamping member 54 and the right clamping member 55 are respectively provided with a left clamping plate 516 and a right clamping plate 517. The left clamping plate 516 and the right clamping plate 517 are respectively provided with a left clamping adjustment hole and a right clamping adjustment hole. The left clamping adjustment hole is connected to the left clamping adjustment block 518 and the right clamping adjustment block 519 through the left adjustment bolt. When it is necessary to adjust according to the bottle mouth diameter, the distance between the left clamping adjustment block 518 and the right clamping adjustment block 519 and the left clamping plate 516 and the right clamping plate 517 is controlled by adjusting the left adjustment bolt and the right adjustment bolt respectively, so as to adjust the clamping size of the left clamping member 54 and the right clamping member 55 back and forth, so as to achieve universal clamping for different bottle mouth outer diameters.

[0036] like Figure 7 As shown, in this embodiment, the output component 7 includes a discharge rack 71 disposed on one side of the feed seat 512. A discharge cylinder 72 is disposed inside the discharge rack 71. An output groove 73, corresponding to the rotating discharge hole 58 on one side of the feed seat 512, is disposed on the upper end of the discharge rack 71. A forward / reverse and height detection platform 74 is disposed on the output groove 73. A conveying slide rail is disposed on the other side of the feed seat 512. A conveying slider 75, connected to the piston rod of the discharge cylinder 72, is disposed on the conveying slide rail. A push rod 76, corresponding to the rotating discharge hole 58 on the other side of the feed seat 512, is disposed on one side of the conveying slider 75. The defective product identification component 8 is disposed on the... On the outside of the discharge rack 71, the defective product identification component 8 includes a support frame, on which a identification cylinder 77 is provided. The piston rod of the identification cylinder 77 is connected to a identification plate 78 corresponding to one side of the front / back and height detection platform 74. The frame 1 has a defective product trough 79 corresponding to the output end of the identification plate 78. After the bottle mouth is laid flat, the discharge cylinder 72 drives the push rod 76 to push the bottle mouth from the feed seat 512 to the output trough 73. The front / back and height detection platform 74 identifies good and defective products by checking the front / back and height of the bottle mouth. The identification cylinder 77 drives the identification plate 78 to push the bottle mouth of the defective product into the defective product trough 79.

[0037] A bottle neck feeding method includes the following steps:

[0038] a. Pushing: The pusher cylinder 411 pushes the bottom plate, front main plate 41, back main plate 42, left inclined plate 44 and right inclined plate 45 to move from bottom to top in the hopper 3. Without a power source, multiple bottle mouths enter the discharge trough 43 and roll along the inclined discharge trough 43 and are sent to the feed trough 513 via the sliding groove. When the bottle mouth rolls in the inclined discharge trough 43, it passes through the gap between the front main plate 41 and the back main plate 42, and along the discharge trough 46 formed between the left inclined plate 44 and the right inclined plate 45, and is discharged through the discharge hole 47 to the waste discharge port 48. In this way, the bottle mouths are pushed out of the hopper 3 by their own weight and the inclined discharge trough 43.

[0039] b. Front and back detection: When the bottle neck step faces left, the left detection plate 66 contacts the bottle neck first, transmitting a low-pressure signal to the right signal transmission bolt 610. The right signal transmission bolt 610 then transmits the signal to the control unit, which controls the detection cylinder 64 to drive the left detection plate 66 and the right detection plate 67 downwards to detect the front and back of the bottle neck. When the bottle neck step faces right, the left detection plate 66 contacts the bottle neck first, transmitting a low-pressure signal to the left signal transmission bolt 69. The left signal transmission bolt 69 then transmits the signal to the control unit, which... The control unit controls the detection cylinder 64 to drive the left detection plate 66 and the right detection plate 67 to move down to detect the front and back of the bottle mouth. When the left detection plate 66 and the right detection plate 67 move down, the inclined surface 611 and the vertical bending surface 612 on the lower inner side of the left detection plate 66 and the V-shaped groove 613 opened at the bottom of the right detection plate 67 cooperate to detect the front and back of the bottle mouth that rolls vertically into the feed trough 513 according to the position of the step surface. This makes it easy for the rotating clamping device to rotate clockwise or counterclockwise according to the front and back of the bottle mouth at different step surface positions.

[0040] c. Clamping and Rotation: When inspecting the bottle opening for both sides, the left detection plate 66 and the right detection plate 67 move downwards, and the inserter 511 also moves downwards. This causes the inserter 511 to control the right clamping member 55 to move with the left clamping member 54 under the action of the elastic connector, thus clamping the bottle opening. After the inspection is completed, the inspection cylinder 64 drives the left detection plate 66 and the right detection plate 67 to move upwards, causing the inserter 511 to move upwards and return to its original position. With the cooperation of the sliding rod 56 and the spring 57, the right clamping member 55 returns to its original position, releasing the bottle opening. If the stepped surface of the bottle opening is on the left, the stepper motor 52 drives the turntable 53 to rotate 90 degrees counterclockwise, so that the bottle opening is flat and the stepped surface is facing upwards. If the stepped surface of the bottle opening is on the right, the stepper motor 52 drives the turntable 53 to rotate 90 degrees clockwise. After clockwise or counterclockwise rotation, the bottle opening enters the output component 7 from the left.

[0041] d. Sorting and Discharging: After the bottle neck is laid flat, the discharge cylinder 72 drives the conveying slider 75 to move, while the push rod 76 pushes the bottle neck from the feed seat 512 to the output groove 73. When the push rod 76 pushes the bottle neck on the output groove 73 past the front-back and height detection table 74, the front-back and height detection table 74 sorts the bottle neck for front-back and height to identify good and bad products. When a bad product cannot be pushed out of the front-back and height detection table 74, the sorting cylinder 77 drives the sorting plate 78 to push the bottle neck of the bad product into the bad product material groove 79. When a good product cannot be pushed out of the front-back and height detection table 74, it continues to be pushed out of the front-back and height detection table 74 until it is pushed to the end of the output groove 73, to a fixed position that the robot arm of the next process can grasp (i.e., the maximum stroke of the discharge cylinder 72).

[0042] The entire feeding process is continuous, smooth, and uninterrupted, effectively improving the feeding efficiency and quality at the bottle opening.

[0043] Based on the ideas of this invention, there may be changes in specific implementation methods and application scope, and the content of this specification should not be construed as a limitation of this invention.

5. A feeding method for a bottle neck feeding device as described in any one of claims 1-4, characterized in that, Includes the following steps: a. Pushing: The pusher cylinder pushes the bottom plate, front main plate, back main plate, left inclined plate and right inclined plate to move from bottom to top in the hopper. Without a power source, multiple bottle mouths enter the discharge chute and roll along the inclined discharge chute to the feed chute. When the bottle mouths roll in the discharge chute, iron pins, broken parts and other debris can be discharged from the gap between the front main plate and the back main plate through the discharge hole along the discharge chute. b. Front and back detection: When the bottle mouth step faces left, the left detection plate contacts the bottle mouth first, transmitting a low-pressure signal to the right signal transmission bolt. The right signal transmission bolt then transmits the signal to the control unit, which controls the detection cylinder to drive the left and right detection plates downward to detect the front and back of the bottle mouth. When the bottle mouth step faces right, the left detection plate contacts the bottle mouth first, transmitting a low-pressure signal to the left signal transmission bolt. The left signal transmission bolt then transmits the signal to the control unit, which controls the detection cylinder to drive the left and right detection plates downward to detect the front and back of the bottle mouth. c. Clamping and Rotation: When checking the front and back of the bottle opening, the left and right detection plates move down, and the insert blade also moves down. This causes the insert blade to control the right clamping part to move with the left clamping part under the action of the elastic connector, thus clamping the bottle opening. If the stepped surface of the bottle opening is on the left, the stepper motor drives the turntable to rotate 90 degrees counterclockwise, so that the bottle opening is flat and the stepped surface is facing up. If the stepped surface of the bottle opening is on the right, the stepper motor drives the turntable to rotate 90 degrees clockwise. After the clockwise or counterclockwise rotation is completed, the bottle opening enters the output component from the left. d. Sorting and discharging: After the bottle mouth is laid flat, the discharge cylinder drives the conveying slider to move, while the push rod pushes the bottle mouth from the feed seat to the output slot. The front and back and height detection table sorts the bottle mouth to identify good and bad products. When a bad product cannot be pushed out of the front and back and height detection table, the sorting cylinder drives the sorting plate to push the bottle mouth of the bad product into the bad product trough.
