Description

Technical Field

[0001] The invention relates to the technical field of bottle unscrambling machines, in particular to an automatic bottle unscrambling production line. Background Art

[0002] Bottle unscrambler is an automated bottle sorting equipment, widely used in production lines of pharmaceutical, food, daily chemical, chemical, light industry and other industries. The existing bottle unscrambler uses the centrifugal force of the disc to bring the bottle close to the outside of the circle, and then uses the different widths of the bottle bottom and bottle mouth to flip the bottle with the bottle mouth facing downward until the bottle is arranged with the bottle mouth facing upward.

[0003] After the bottles are arranged, the unscrambler usually moves along the guide rail to the filling production line for filling operations. However, before the filling operation, there is no equipment or device on the production line to detect the air tightness of the bottles in time, which causes some bottles to leak liquid due to poor sealing, thus affecting subsequent production.

[0004] To this end, the present invention provides an automatic bottle unscrambling production line. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The present invention provides an automatic bottle unscrambling production line, comprising a bottle unscrambling machine and a bottle outlet provided on the bottle unscrambling machine; A set of columnar guide rails are installed at the bottle outlet to guide the bottle to move; A support frame is installed on the outer wall of the bottle unscrambler housing, and a detection component is installed on the support frame for detecting the sealing of the inside of the bottle; The support frame is provided with a positioning component, and the positioning component is provided with a linkage component for driving the detection component to rise and fall, and is used to cooperate with the detection component to detect the sealing of the bottles one by one.

[0007] Preferably, the detection assembly includes an air pump, a bellows, a bottle cap and a pressure sensor; An air pump is installed on the support frame, and a bellows is connected to the air outlet of the air pump. The bottom end of the bellows is connected to a bottle cap, and a pressure sensor is installed on the bottle cap. The bottle cap is pressed on the surface of the bottle mouth, and the air pump slowly fills the bottle with gas through the bellows and the bottle cap. The inflation speed should not be too fast to avoid impacting the pressure sensor due to excessive instantaneous pressure and causing the pressure change in the bottle to be too drastic and difficult to detect accurately. During the inflation process, the reading of the pressure sensor is continuously observed. When the pressure in the bottle reaches a preset test pressure value, the air pump is turned off, the inflation operation is stopped, and the initial pressure value P displayed by the pressure sensor is recorded. Then the bottle is allowed to stand for a period of time. After standing, the final pressure value P displayed by the pressure sensor is recorded, and the pressure change value P=PP is calculated. If P is within the allowable error range, it can be determined that the bottle has good air tightness; otherwise, if it exceeds the set error range, it means that the bottle has air leakage and the air tightness does not meet the requirements, thereby completing the air tightness detection of the bottle.

[0008] Preferably, an air inlet is provided inside the bottle cap, and a one-way valve for air intake only is installed inside the air inlet; under the action of the one-way valve, gas can be prevented from flowing back to the bellows. After the bottle is inflated with air by the air pump to reach the set pressure, even if the air pump stops working or the external air pressure fluctuates, the setting of the one-way valve can also prevent the gas in the bottle from flowing back to the air pump. In this way, the air pressure in the bottle can be maintained in a relatively stable state for a period of time, so that the subsequent detection and judgment of air pressure changes by the pressure sensor can be more accurate.

[0009] Preferably, a sealing ring is installed at the bottom end of the bottle cap, and the outer wall of the sealing ring is in contact with the inner wall of the bottle mouth; when the bottle is inflated to a set pressure and is ready to start testing, the sealing ring can ensure that the air pressure in the bottle remains stable in the initial stage, which avoids gas leakage due to loose sealing at the bottle mouth, so that the set initial pressure value can be used as an accurate benchmark for subsequent judgments on changes in sealing.

[0010] Preferably, the positioning assembly includes a servo motor, a screw, a gear, a first rack plate and a second rack plate; A servo motor is installed on the support frame, and a screw is sleeved on the output end of the servo motor. The screw is rotatably connected to the support frame, and a gear is sleeved on the portion without a thread groove at the lower end of the screw. The outer wall of the gear is symmetrically meshed with a first rack plate and a second rack plate, and the front end of the first rack plate is attached to the outer wall of the bottle; one end of the first rack plate is driven to attach to the outer wall of the bottle through the positioning component, thereby positioning the bottle to prevent the bottle from continuing to move on the guide rail.

[0011] Preferably, the support frame is provided with two plate grooves, and the first rack plate and the second rack plate are slidably connected inside the two plate grooves respectively, which can limit the movement of the first rack plate and the second rack plate.

[0012] Preferably, a triangular plate is connected to the front end of the second rack plate; when the second rack plate drives the triangular plate to move forward synchronously, the triangular plate squeezes the bottle, thereby driving the detected bottle to move on the guide rail, so that the detected bottle is automatically separated from the undetected bottle.

[0013] Preferably, the linkage assembly comprises a connecting rod, a slide groove and a vertical rod; The outer wall of the screw is connected to a connecting rod by a thread, a slide groove is provided inside the support frame, the outer wall of the connecting rod is slidably connected to the inside of the slide groove, the bottom end of the connecting rod is connected to the bottle cap, the top end of the connecting rod is connected to a vertical rod, and the vertical rod is slidably connected to the support frame; when the first rack plate moves forward to block the outer wall of the bottle, the vertical rod moves downward to drive the bottle cap onto the bottle, which can subsequently perform an air tightness detection on the bottle, and when the first rack plate moves back and the second rack plate moves forward, the detected bottle can be driven to separate from the undetected bottle, thereby separating the bottles.

[0014] The beneficial effects of the present invention are as follows: the automatic bottle unscrambling production line of the present invention arranges and sorts a plurality of bottles through a bottle unscrambler and then moves the bottles along the bottle outlet to the guide rail, then positions the bottles directly below the detection component through a positioning component, then moves the bottle cap and the sealing ring to the bottle mouth through a linkage component, and then air is introduced into the bottle through an air pump until the pressure in the bottle reaches a preset test pressure value, then the air pump is turned off, the bottle is left to stand, and finally the pressure sensor is used for detection again. Through the cooperation of a plurality of components, each bottle coming out of the bottle unscrambler can be tested for air tightness one by one, thereby not affecting subsequent filling operations.

[0017] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples. Example

[0018] like Figures 1 to 6 As shown, the automatic bottle unscrambling production line of the embodiment of the present invention comprises a bottle unscrambling machine 1 and a bottle outlet 11 provided on the bottle unscrambling machine 1; A set of columnar guide rails 2 are installed at the bottle outlet 11 to guide the bottle to move; A support frame 3 is installed on the outer wall of the bottle unscrambler 1 shell, and a detection component 4 is installed on the support frame 3 for detecting the sealing of the inside of the bottle; The support frame 3 is provided with a positioning assembly 5 , and the positioning assembly 5 is provided with a linkage assembly 6 for driving the detection assembly 4 to rise and fall, and is used to cooperate with the detection assembly 4 to detect the sealing of the bottles one by one.

[0019] Specifically, the bottle unscrambler 1 arranges and sorts a plurality of bottles and moves them along the bottle outlet 11 to the guide rail 2, then positions the bottle directly below the detection component 4 through the positioning component 5, and then moves the bottle cap 43 and the sealing ring 45 to the bottle mouth through the linkage component, and then the air pump 41 is used to inject air into the bottle until the pressure in the bottle reaches a preset test pressure value, then the air pump 41 is turned off, the bottle is left to stand, and finally the pressure sensor 44 is used to perform another test. Through the cooperation of multiple components, each bottle coming out of the bottle unscrambler 1 can be tested for air tightness one by one, thereby not affecting the subsequent filling operation.

[0020] Please refer to Figure 3 , Figure 4 , the detection assembly 4 includes an air pump 41, a bellows 42, a bottle cap 43 and a pressure sensor 44; An air pump 41 is installed on the support frame 3 , an air outlet of the air pump 41 is connected to a bellows 42 , a bottom end of the bellows 42 is connected to a bottle cap 43 , and a pressure sensor 44 is installed on the bottle cap 43 .

[0021] Specifically, the bottle cap 43 is pressed on the surface of the bottle mouth, and the air pump 41 slowly fills the bottle with gas through the bellows 42 and the bottle cap 43. The inflation speed should not be too fast to avoid impact on the pressure sensor 44 due to excessive instantaneous pressure and excessive pressure changes in the bottle that are difficult to detect accurately. During the inflation process, the reading of the pressure sensor 44 is continuously observed. When the pressure in the bottle reaches a preset test pressure value, the air pump 41 is turned off, the inflation operation is stopped, and the initial pressure value P1 displayed by the pressure sensor is recorded. Then the bottle is allowed to stand for a period of time. After standing, the final pressure value P2 displayed by the pressure sensor is recorded, and the pressure change value P3=P1-P2 is calculated. If P3 is within the allowable error range, it can be determined that the bottle is airtight. On the contrary, if it exceeds the set error range, it means that the bottle is leaking and the airtightness does not meet the requirements, thereby completing the airtightness test of the bottle.

[0022] Please refer to Figure 4 An air inlet 431 is provided inside the bottle cap 43 , and a one-way valve 432 for air intake is installed inside the air inlet 431 .

[0023] Specifically, the gas from the air pump 41 is sucked into the bottle through the air inlet 431 on the bottle cap 43. Under the action of the one-way valve 432, the gas can be prevented from flowing back to the bellows 42. After the bottle is inflated by the air pump 41 to reach the set pressure, even if the air pump 41 stops working or the external air pressure fluctuates, the setting of the one-way valve 432 can also prevent the gas in the bottle from flowing back into the air pump 41. In this way, the air pressure in the bottle can be maintained in a relatively stable state for a period of time, so that the subsequent detection and judgment of the air pressure change by the pressure sensor 44 can be more accurate.

[0024] Please refer to Figure 4 A sealing ring 45 is installed at the bottom end of the bottle cap 43, and the outer wall of the sealing ring 45 is in contact with the inner wall of the bottle mouth.

[0025] Specifically, when the gas in the bottle reaches the set pressure and is ready to start testing, the sealing ring 45 can ensure that the air pressure in the bottle remains stable in the initial stage, which avoids gas leakage due to loose sealing at the bottle mouth, so that the set initial pressure value can be used as an accurate benchmark for subsequent judgment of sealing changes.

[0026] Please refer to Figure 3 , Figure 5 , Figure 6 , the positioning assembly 5 includes a servo motor 51, a screw 52, ​​a gear 53, a first rack plate 54 and a second rack plate 55; A servo motor 51 is installed on the support frame 3, and a screw 52 is sleeved on the output end of the servo motor 51. The screw 52 is rotatably connected to the support frame 3. A gear 53 is sleeved on the portion without a thread groove at the lower end of the screw 52. The outer wall of the gear 53 is symmetrically meshed with a first rack plate 54 and a second rack plate 55, and the front end of the first rack plate 54 is attached to the outer wall of the bottle.

[0027] Specifically, when the bottles are arranged and sorted by the bottle unscrambler 1 and leave through the bottle outlet 11, the bottles move on the guide rail 2 until the bottles move to just below the detection component 4, and the servo motor 51 drives the screw 52 to rotate on the support frame 3. The rotation of the screw 52 drives the gear 53 to rotate synchronously, and then the gear 53 drives the first rack plate 54 and the second rack plate 55 to move in the opposite direction until one end of the first rack plate 54 is in contact with the outer wall of the bottle, thereby positioning the bottle and preventing the bottle from continuing to move on the guide rail 2.

[0028] Please refer to Figure 3 The support frame 3 is provided with two plate grooves 56 , and the first rack plate 54 and the second rack plate 55 are slidably connected inside the two plate grooves 56 , respectively.

[0029] Specifically, the first rack plate 54 and the second rack plate 55 will slide in the plate groove 56 on the support frame 3 when moving, thereby limiting the movement of the first rack plate 54 and the second rack plate 55 .

[0030] Please refer to Figure 5 , Figure 6 The front end of the second rack plate 55 is connected to a triangular plate 57 .

[0031] Specifically, when the bottle has completed the sealing inspection, the servo motor 51 rotates in the opposite direction, so that the first rack plate 54 moves back and the second rack plate 55 moves forward, so that the second rack plate 55 drives the triangular plate 57 to move forward synchronously, so that the triangular plate 57 squeezes the bottle, thereby driving the inspected bottle to move on the guide rail 2, so that the inspected bottle is automatically separated from the uninspected bottle.

[0032] Please refer to Figure 3 , Figure 5 , Figure 6 , the linkage assembly 6 includes a connecting rod 61, a slide groove 62 and a vertical rod 63; The outer wall of the screw rod 52 is connected to a connecting rod 61 through a thread, a slide groove 62 is opened inside the support frame 3, the outer wall of the connecting rod 61 is slidably connected inside the slide groove 62, the bottom end of the connecting rod 61 is connected to the bottle cap 43, and the top end of the connecting rod 61 is connected to a vertical rod 63, and the vertical rod 63 is slidably connected to the support frame 3.

[0033] Specifically, the screw rod 52 is driven to rotate by the servo motor 51, thereby driving the connecting rod 61 on the screw rod 52 to move up and down. Under the action of the slide groove 62, the connecting rod 61 is prevented from rotating synchronously with the screw rod 52. When the connecting rod 61 moves up and down, it drives the vertical rod 63 to slide on the support frame 3, and then drives the bottle cap 43 to move. When the first rack plate 54 moves forward to block the outer wall of the bottle, the vertical rod 63 moves downward to drive the bottle cap 43 onto the bottle, which can subsequently play a role in air tightness detection of the bottle. When the first rack plate 54 moves back and the second rack plate 55 moves forward, it can drive the detected bottle to be separated from the undetected bottle, thereby separating the bottles.

[0034] Working principle: After the bottles are arranged and sorted by the bottle unscrambler 1 and leave through the bottle outlet 11, the bottles move on the guide rail 2 until the bottles move to the bottom of the detection assembly 4, and the servo motor 51 drives the screw 52 to rotate on the support frame 3, and the screw 52 rotates while driving the gear 53 to rotate synchronously, so that the gear 53 drives the first rack plate 54 and the second rack plate 55 to move in the opposite direction, until one end of the first rack plate 54 fits against the outer wall of the bottle, thereby positioning the bottle and preventing the bottle from continuing to move on the guide rail 2; The servo motor 51 drives the screw 52 to rotate, thereby driving the connecting rod 61 on the screw 52 to move up and down. Under the action of the slide groove 62, the connecting rod 61 is prevented from rotating synchronously with the screw 52. The connecting rod 61 moves up and down while driving the vertical rod 63 to slide on the support frame 3, thereby driving the bottle cap 43 to move. When the bottle cap 43 is pressed on the surface of the bottle mouth, the air pump 41 slowly fills the bottle with gas through the bellows 42 and the bottle cap 43. The inflation speed should not be too fast to avoid the impact on the pressure sensor 44 caused by excessive instantaneous pressure and the excessive change of the pressure in the bottle that is difficult to detect accurately. During the inflation process, the pressure sensor 44 is kept at a constant level to prevent the pressure sensor 44 from being impacted by excessive instantaneous pressure and the pressure in the bottle from changing too drastically and being difficult to detect accurately. Continue to observe the reading of the pressure sensor 44. When the pressure in the bottle reaches the preset test pressure value, turn off the air pump 41, stop the inflation operation, record the initial pressure value P1 displayed by the pressure sensor at this time, and then let the bottle stand for a period of time. After standing still, record the final pressure value P2 displayed by the pressure sensor at this time, and calculate the pressure change value P3=P1-P2. If P3 is within the allowable error range, it can be determined that the bottle is airtight. On the contrary, if it exceeds the set error range, it means that the bottle is leaking and the airtightness does not meet the requirements, thereby completing the airtightness test of the bottle; When the bottle has completed the sealing inspection, the servo motor 51 rotates in the opposite direction, so that the first rack plate 54 moves back and the second rack plate 55 moves forward, so that the second rack plate 55 drives the triangular plate 57 to move forward synchronously, so that the triangular plate 57 squeezes the bottle, thereby driving the inspected bottle to move on the guide rail 2, so that the inspected bottle is automatically separated from the uninspected bottle.

A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
