Description

Technical Field

[0001] The invention relates to the technical field of bottle blank production and processing, in particular to a bottle blank visual inspection and tail cutting integrated machine and a use method thereof. Background Art

[0002] In the production and processing of bottle blanks, the bottle blanks usually need to be processed through multiple processes, including basic processes such as injection molding, cooling, and demoulding of the bottle blanks. These processes lay the foundation for the basic molding of the bottle blanks. However, in the subsequent processing flow, many aspects of refined processing are still required, among which visual inspection and tail cutting are two important links. Visual inspection mainly tests the appearance, internal structure and key parts of the bottle blanks to ensure that the quality of the bottle blanks meets the requirements of subsequent production; and the tail cutting process is to shear the excess part of the tail of the bottle blank during the molding process to avoid the excess part from causing adverse effects on subsequent processing or product use, while ensuring the aesthetics and dimensional accuracy of the product.

[0003] Traditional preform processing equipment usually separates the inspection and tail cutting processes, which requires the use of different equipment to complete them respectively, resulting in a decentralized production process and occupying more production space.

Then, the external thread detection camera and the blank body detection camera are used to collect and detect the external thread and blank body of the bottle blank, thereby completing the visual inspection of the bottle blank.

[0014] The present invention provides a bottle blank visual inspection and tail cutting integrated machine and a use method thereof. It has the following beneficial effects: 1. The present invention drives the turntable and the elastic preform capping star-shaped disk to operate through the second servo motor, adjusts the height of the tail cutting knife structure through the tail cutting knife holder to cut the tail, drives the synchronous belt through the servo motor to rotate the preform in the turntable, and performs comprehensive image acquisition and detection of the inner bottom, mouth plane, external thread and preform body of the preform through the first camera group and the second camera, thereby integrating the visual inspection and tail cutting processes of the preform on one device, avoiding the frequent transfer of the preform between different devices, reducing the turnover times and intermediate links of the preform, and thus enhancing the production efficiency.

[0015] 2. The present invention uses a fixed ring to fit the outer wall of the bottle blank when the bottle blank enters the elastic bottle blank capping star disk, so that a certain elastic buffer and limit are provided according to the size and shape of the bottle blank through the support connecting rod and the spring, so that the bottle blanks of different specifications are separated and transported, and the support connecting rod slides smoothly through the sliding sleeve, thereby ensuring the stability and reliability of the entire capping process, avoiding damage due to misalignment when clamping the bottle blank, thereby improving the situation that the hard star wheel disk is very easy to damage the bottle blank and cause scrapping, and the damage is more serious during high-speed separation.

[0016] 3. The present invention uses an adjustable height tail cutting knife holder to adjust the height of the tail cutting knife structure according to the tail cutting requirements of the bottle blank. When the bottle blank reaches the tail cutting knife structure, the vacuum negative pressure suction label with a pulley is driven by a cam mechanism to drive the bottle blank into the interior of the blank bottom fixing fixture, and then the fixed bottle blank is driven to pass through the tail cutting knife structure through the rotation of the turntable to perform the tail cutting operation on the bottle blank, and then the turntable continues to rotate, so that the vacuum negative pressure suction label with a pulley drives the bottle blank to leave the interior of the blank bottom fixing fixture, thereby completing the tail cutting operation.

[0017] 4. The present invention integrates the visual inspection and tail cutting processes and utilizes an integrated structure composed of a bottom cabinet, an elastic preform capping star-shaped plate, a turntable and other components to achieve continuous processing of the preforms in the same device. From the preforms entering the device, being separated and transported by the elastic preform capping star-shaped plate, to the visual inspection and tail cutting operations on the turntable, there is no need to transfer between different devices, thus avoiding the time waste caused by equipment conversion and preform transportation in the traditional way, greatly shortening the production cycle and increasing the output per unit time.

[0018] 5. The present invention reduces manual intervention by automatically completing the feeding, transmission, visual inspection and tail cutting processes of the preforms inside the integrated machine. The operator only needs to operate on one device and does not need to be familiar with and switch the operating procedures and parameter settings of different devices, thereby reducing the operating difficulty and error probability and improving the convenience and efficiency of operation.

The outer wall of one side of the synchronous belt 12 is in contact with the pulley of the vacuum negative pressure suction label 18 with a pulley follower, and the tooth end of the second transmission gear 21 is meshed with the tooth end of the first transmission gear 34. A second servo motor is fixedly arranged on one side of the interior of the bottom cabinet 1, and the output end of the second servo motor is fixedly arranged at the bottom of the second transmission gear 21.

[0023] Specifically, the turntable 10 adopts a 32-head high-density turntable, and the tail cutting knife holder 23 adopts an adjustable height tail cutting knife holder. It is operated by a second servo motor on one side of the bottom cabinet 1 to drive the second transmission gear 21 to rotate, thereby driving the turntable 10 to operate, and the bottle blank is adsorbed by the vacuum negative pressure suction label 18 with a pulley follower. Through the operation of the servo motor 11, the synchronous belt 12 is driven to operate on the gear set 13, and then the pulley of the vacuum negative pressure suction label 18 with a pulley follower is driven to rotate through the outer wall of the synchronous belt 12, thereby driving the adsorbed bottle blank to rotate, so that the external thread and the blank body of the adsorbed bottle blank are fully imaged and detected by the second camera group.

[0024] The preforms are delivered to the feeding port of the elastic preform capping star disk 16 through the air delivery track 15, and the meshing transmission of the second transmission gear 21 and the first transmission gear 34 transmits power to the elastic preform capping star disk 16, so that the elastic preform capping star disk 16 operates, thereby separating and conveying the preforms, and the first camera group collects and detects images of the inner bottom and the mouth plane of the preform, thereby completing a full range of visual inspection operations.

[0025] The height of the tail cutting knife structure 17 is adjusted according to the tail cutting requirement of the preform by the height-adjustable tail cutting knife holder 23. When the qualified preform reaches the tail cutting knife structure 17 under the rotation of the turntable 10, the vacuum negative pressure suction label 18 with pulley follower is sunk through the cam mechanism 37, thereby driving the preform to enter the interior of the preform bottom fixing fixture 38, and then the fixed preform is driven to pass through the tail cutting knife structure 17 to perform the tail cutting operation on the preform through the rotation of the turntable 10, and then the turntable 10 continues to rotate, so that the vacuum negative pressure suction label 18 with pulley follower is sunk.

[0026] Please see attached Figure 3 , Attachment Figure 5 The elastic preform capping star disk 16 includes a main shaft 33, the bottom end of the main shaft 33 is fixedly connected to the top of the first transmission gear 34, the middle part of the main shaft 33 is installed on the top of the bottom cabinet 1, and the top of the main shaft 33 is fixedly connected to a connecting plate 36, the circumferential outer wall of the connecting plate 36 is evenly provided with grooves, a spring 30 is provided on one side of the groove of the connecting plate 36, a sliding sleeve 31 is installed on the inner wall of the groove of the connecting plate 36, and a supporting connecting rod 32 is slidably connected to the inner wall of the sliding sleeve 31, one end of the supporting connecting rod 32 is connected to one end of the spring 30, and the other end of the supporting connecting rod 32 is fixedly provided with a fixing ring 35.

[0027] Specifically, the main shaft 33 not only stably mounts the elastic preform capping star plate 16 on the bottom cabinet 1, but also connects with the first transmission gear 34 through the bottom end, so that the elastic preform capping star plate 16 can receive the power from the second transmission gear 21. On the outer circumferential wall of the connecting plate 36 at the top, springs 30 and sliding sleeves 31 are arranged in evenly distributed grooves. One end of the supporting connecting rod 32 is connected to the spring 30, and the other end is fixed to the fixing ring 35. When a preform enters, the fixing ring 35 and the preform are connected. The outer wall of the bottle blank is fitted, so that the supporting connecting rod 32 and the spring 30 provide a certain elastic buffer and limit according to the size and shape of the bottle blank, so that the bottle blanks of different specifications can be better positioned and processed, and the sliding shaft sleeve 31 ensures the smooth sliding of the supporting connecting rod 32, thereby ensuring the stability and reliability of the entire capping process, thereby avoiding damage due to misalignment when clamping the bottle blank, thereby improving the situation that the hard star wheel is very easy to damage the bottle blank and cause scrapping, and the damage is more serious during high-speed separation.

[0028] Please see attached Figure 3 , Attachment Figure 6 The tail cutting knife structure 17 includes a screw rod 28, the top of which is mounted on one side of the tail cutting knife holder 23, the outer wall of the screw rod 28 is threadedly connected with a blade fixing bracket 26, one side of the blade fixing bracket 26 is fixedly connected with a guide sleeve 27, the top of the blade fixing bracket 26 is symmetrically mounted with a tail cutting blade 25, a fixing plate 24 is fixedly provided on one side of the top of the blade fixing bracket 26, one side of the fixing plate 24 is fitted with one side of the tail cutting blade 25, the bottom of the blade fixing bracket 26 is symmetrically fixedly connected with a fixing shaft 29, the bottom end of the fixing shaft 29 passes through the top of the base cabinet 1 and is located inside the base cabinet 1, and the outer wall of the fixing shaft 29 is slidably connected to the top of the base cabinet 1.

[0029] Specifically, the screw 28 is installed on one side of the tail cutting knife holder 23. When cutting the tail of the bottle blank, the screw 28 is adjusted by the tail cutting knife holder 23 to make the blade fixing bracket 26 move up and down along the thread of the screw 28, so as to adjust the height position of the tail cutting blade 25 to meet the cutting requirements of the tail of the bottle blank of different lengths. The guide sleeve 27 can provide guidance for the movement of the blade fixing bracket 26 to ensure the linearity and stability of its movement. At the same time, the fixing plate 24 on the top of the blade fixing bracket 26 is in contact with one side of the tail cutting blade 25. The fixing plate 24 plays a certain supporting and fixing role on the tail cutting blade 25 to prevent the tail cutting blade 25 from shifting during operation. The fixing shaft 29 at the bottom runs through the top of the bottom cabinet 1, so that the entire tail cutting knife structure 17 can be stably installed on the bottom cabinet 1, and it can slide up and down on the top of the bottom cabinet 1. The blade fixing bracket 26 is limited when it moves, so that its movement is more stable, and the stability of the entire structure can be ensured during the tail cutting process.

[0031] Specifically, the turntable 10 is limited by the limiting column 19 to make it more stable and facilitate the installation of the gear set 13. When the bottle blank moves through the elastic bottle blank cover star disk 16, the inner bottom detection camera 6 captures and detects the image of the inner bottom of the bottle blank. When the bottle blank moves through the elastic bottle blank cover star disk 16, the plane detection camera 7 captures and detects the image of the mouth plane of the bottle blank. By capturing and analyzing the images of these key parts, it is determined whether the bottle blank meets the quality standards. When the bottle blank moves through the turntable 10, the external thread detection camera 8 captures and detects the image of the external thread of the bottle blank. When the bottle blank moves through the turntable 10, the body detection camera 9 captures and detects the body of the bottle blank. Through these multi-angle detections, it is ensured that the appearance and structure of the bottle blank meet the production requirements, thereby completing the visual inspection of the bottle blank.

[0034] Please see attached Figure 7 The method of using the bottle blank visual inspection and tail cutting integrated machine includes the following steps: S1. When in use, the preform is sent to the elastic preform capping star plate 16 through the first preform inlet 20 and the air delivery track 15; S2, the second servo motor then drives the second transmission gear 21 to rotate, thereby driving the first transmission gear 34 to rotate, and driving the elastic preform capping star disk 16 to operate, so that the fixing ring 35 fits the outer wall of the preform, so that the support link 32 and the spring 30 provide elastic buffering and limiting according to the size and shape of the preform, so that the preforms of different specifications can be positioned and processed, and the support link 32 slides smoothly through the sliding sleeve 31; S3, when the preform moves through the elastic preform capping star plate 16, the inner bottom detection camera 6 and the plane detection camera 7 collect and detect the inner bottom and the mouth plane of the preform, and then the qualified preforms leave through the good product outlet 4, and the unqualified preforms are discharged through the waste discharge hopper 3; S4, the preform is fed into the turntable 10 through the second preform inlet 22, the turntable 10 is driven to run by the rotation of the second transmission gear 21, and the preform is adsorbed by the vacuum negative pressure suction labeling 18 with a pulley following; S5, the height of the tail cutting knife structure 17 is adjusted according to the preform by the height-adjustable tail cutting knife holder 23.
