Description

Grouped filling bottle liquid impurity detecting device and method

Technical field

The present invention relates to a device and method for detecting impurities contained in a liquid in a transparent bottle, and more particularly to the detection of impurities contained in a liquid in a transparent bottle of a pharmaceutical or food industry. Background technique

Due to the production process and packaging technology, bottled liquid products may contain foreign matter such as fibers, rubber crumbs, glass chips, and aluminum chips. If these foreign substances are used together with the liquid, it will cause great harm to the health of the human body. In particular, liquid medicines contain impurities. For example, impurities in ampoules injections enter human blood, causing diseases such as phlebitis, blood clots, stroke, edema, etc., and vascular clogging, rupture, visceral damage, and even crisis life. Therefore, it is necessary to test the quality of the bottled liquid.

At present, the detection of impurities in domestic bottled liquid products is mainly based on manual testing. However, manual testing is mainly an emotional judgment, and the quality of detection is difficult to guarantee. As people's requirements for the quality of filling liquids are getting higher and higher, especially the production of modern filling liquids has higher requirements for detection accuracy, the traditional manual testing can no longer meet the requirements of the pharmaceutical industry.

The existing domestic and international bottled liquid impurity detecting equipment, commonly known as the light inspection machine, is a sequential transmission method. The filling bottle is a bottle and a bottle is introduced into the detecting main wheel through the feeding bottle wheel, and then passed out. The bottle of the wheel is transferred in a sequence of one bottle and one bottle. According to the motion state of the camera that shoots the image of the bottle, there are two ways to realize the sequential transmission: One is the Chinese invention patent (application number: 200510042615. 1, public number: CN 1760666 A) "An ampoule pharmacy Detection method and system "The disclosed method: the imaging mode of synchronous tracking with the detection of the main wheel, that is, the camera follows the bottle body synchronous movement, and after shooting the sequence image of the filling bottle, it is reset to the initial position of the image; the other is The method stipulated in the invention patent (application number: 03124859. 4, publication number: CN1529165A, "automatic bottled medicine detector" disclosed method): intermittent stationary imaging mode, that is, detecting the main wheel stepping rotation During the rest of its momentary pause, the camera takes a sequence of images of the filling bottle.

The rotary bottle station, the brake station and the inspection station of the two types of light inspection machine devices for realizing the above sequential transmission mode are distributed on the circumference of the detection main wheel, and the liquid is rotated in the state of the filling bottle, different stations The movement between them can cause bubbles in the filling bottle. When the filling bottle is accelerated to rotate and brake, the rotary bottle bearing of the clamping unit is horizontally biased, causing the rotating bottle shaft to tilt, which also causes bubbles in the filling bottle. The bubbles in the filling bottle and the impurities in the fiber are difficult to distinguish and distinguish on the captured image, which affects the detection result, even missed or misjudged. The rotary bottle station, the brake station and the inspection station of the existing detection mode of the light inspection machine cannot overlap at one station, which causes bubbles in the filling bottle, and the phenomenon that affects the detection result cannot be avoided. The liquid rotary motion drives the insoluble impurity particles precipitated in the filling bottle; the fiber-like impurities with a small specific gravity float up as soon as the rotation speed exceeds a certain low value; and the glass crumb-like impurities are more important than When the speed exceeds a certain value, it will float. The main reason for the poor detection rate of the existing light inspection machine is: When the rotation speed reaches the level of the important impurities, it often causes the fiber-like impurities with a small specific gravity to be suspended to the liquid surface, which cannot be inspected, and the viscosity of the liquid And the amount of filling has a certain influence on the floating of impurities. The existing domestic and foreign sequential transmission mode light inspection machines are all single speed setting mode detection, as described in the above-mentioned Chinese invention patent "An ampoule reagent detection method and system": The filling bottle is accelerated and rotated When the speed is reached to a set value, the brake will stop and the image will be taken. The root of the detection of the single speed set value mode lies in the sequential transmission mode of the existing light inspection machine. The rotary bottle, brake, and detection are not in one station, and the rotation speed of the rotary bottle cannot be adjusted at the inspection station, and the specific gravity cannot be obtained. A variety of images in which various impurities are successively floated. The technical bottleneck problem that the detection method of the single-speed set value mode of the existing lamp inspection machine is not good is difficult to overcome.

Another particularly prominent drawback of the light inspection machine based on the above sequential transmission method is the broken bottle phenomenon. When the bottle body is input into the infeed bottle wheel, the main wheel plate, and the bottle wheel, the bottle body is broken due to the inclination of the bottle body or the bottle body not being cut into the bayonet of the wheel plate. . The accumulation of broken bottles and the sequential transfer method keep the bottle broken, which causes great losses to the manufacturer of the bottle. For example, the Chinese utility model patent (patent application number: 201120327933. 3, authorization announcement number: CN 202213756 U) discloses a "breaking bottle detecting device used in an automatic light inspection machine", which reflects the existing light inspection machine. The detection method and the system structure are helpless to the bottle body breaking phenomenon, and the fundamental problem of the broken bottle cannot be solved technically, but only by means of broken bottle detection, rapid automatic shutdown, and then human intervention. The clean-up of human intervention is very time-consuming and laborious, which seriously reduces the efficiency of the machine. The sequential transmission mode of the existing light inspection machine cannot bypass the technical means of transferring the filling bottle between the roulette mounts, and the technical barrier of the broken bottle cannot be exceeded.

The light inspection machine equipment for realizing the above sequential transmission mode generally includes: a rotary work table, detecting a main wheel disk, a bottle feeding wheel disk, a bottle discharging wheel plate and other auxiliary linkage mechanisms, so that the structure of the entire device is extremely complicated, resulting in the existing domestic The external light inspection equipment has the defects of high cost, bulkiness and bulkiness. At the same time, it has to use 380V industrial power for driving these wheels, so that the existing light inspection equipment has high power consumption and noise. A big common problem.

Therefore, pharmaceutical and food manufacturers urgently need a lamp inspection machine with high detection rate, reliable operation, no bottle breakage, strong adaptability to viscosity and filling volume, and high intelligence level instead of manual detection. Based on this, the present invention provides a group-type filling bottle liquid impurity detecting device and method, which effectively improves various defects and technical problems existing in the existing lamp inspection machine.

The group clamping mechanism 30 rotates synchronously with the orthogonal motion output indexing table 20, and the indexing rotation positioning of the orthogonal motion output indexing table 20 can realize the one-stage clamping mechanism 30 in the one detection working cycle. The working position of the three working states: the orientation of the initial position of the bottle 1010, the inspection station 1023, and the bottle unloading station 1040. The pressure bottle cover 33 and the bottle holder 34 of the group clamping mechanism 30 can be synchronously rotated following the group clamping mechanism 30; driven by the horizontal motion outputted by the orthogonal motion output indexing table 20, and can be radially reciprocated horizontally Moving; driven by the vertical motion outputted by the orthogonal motion output indexing table 20, the bottle holder 34 can be vertically moved up and down along with the lifting plate 35, and the bottle holder 34 is connected to the rotary bottle motor 348 and the angle sensor 349, the rotary bottle motor 348. The angle sensor 349 provides rotational driving and corner positioning; therefore, the group clamping mechanism 30 can realize the operations of group clamping, simultaneous movement, simultaneous detection, and simultaneous unloading.

As shown in Fig. 2, a plurality of parallel vial spacers 69 are provided on the vial tray 68 in the bottle feeding mechanism 60. The spacers 69 are spaced apart from each other and the vial tray 68 is provided. A plurality of parallel guide flasks 65 are formed together, and a row of filling bottles 66 is supported on the guide bottle tray 68 in each of the guide bottle slots 65. The group clamping mechanism 30 simultaneously takes each time. The first filling bottle 66 of the front row of the filling bottles forms a combination of the grouped filling bottles 66 to be tested.

In this embodiment, the vial port 691 is a V-shaped port formed by two adjacent vial spacers 69 on the inner side of the slot, that is, a vial V-port 691, the vial V-port 691 can ensure that the center of the filling bottle 66 coincides with the center line of the notch of the guide bottle slot 65, thereby realizing the automatic positioning of the filling bottle 66.

In the present embodiment, the guide bottle opening 686 is opened on the guide bottle tray 68 below the first row of filling bottles 66 in the guide bottle groove 65, that is, the special shape gap 686, and the special shape gap 686 is Two small trapezoidal notches 682 and one large rectangle The gap 681 is composed. Two small trapezoidal notches 682 are symmetrically distributed on both sides of the notch centerline of the guide bottle groove 65, and the edge of one side of the two small trapezoidal notches 682 is to the second bottle in the notch of the guide bottle groove 65. The shortest horizontal distance is equal to the shortest horizontal distance from the edge of the other side bevel to the vial spacer 69. The large rectangular notch 681 is below the vial V-port 691 and is the same width as the vial V-port 691.

In the present embodiment, the knob holder 34 is a circular table having three backrests distributed along the circumference: two low backrests 342 and one high backrest 341. The distribution positions of the three backrests correspond to the distribution positions of the three notches of the special shape notch 686 of the guide bottle holder 68: that is, the two lower backrests 342 correspond to the two small trapezoidal notches 682, and the high backrest 341 corresponds to the large rectangular notch 681. Each backrest is sized smaller than its corresponding notch size, ensuring that the bottle holder 34 can pass through the special shaped notch 686 into the guide bottle slot 65 to lift the filling bottle 66 up. The spinner motor 348 functions to drive the rotation of the knob holder 34; the angle sensor 349 functions to position the azimuths of the three backrests of the knob holder 34; the group clamping mechanism 30 is secured and the needle holder 34 is placed thereon. When the bottle feeding mechanism 60 and the sorting mechanism 80 are moved in the horizontal direction, the centers of the two low backrests 342 and the center of the high backrest 341 coincide with the moving direction; and the two low backrests 342 are on the outer side and the high backrest 341 is on the inner side. The function of the three backs is to prevent the bottle from being thrown out when the bottle is rotated, and also to increase the contact area between the filling bottle 66 and the bottle holder 34, so as to prevent the two from slipping when the bottle is rotated. Rotating bottle holder The inner bottom surface of the 34 round table is designed as a conical surface to ensure the automatic centering of the bottom of the filling bottle 66 in the revolving bottle holder 34.

The lower part of the round table of the knob holder 34 is a hollow support rod 347 through which the knob holder 34 is placed on the lifting plate 35; the diameter of the support rod 347 is smaller than the width of the V-shaped port 691 of the guide bottle, and the support in an upright state The rod 347 can be withdrawn from the guide via 65 through the vial V-port 691.

At the initial bottle dispensing station 1010, the orthogonal motion output indexing table 20 is output by three consecutive motions: horizontal motion of the horizontal motion output 21 to the bottle feeding mechanism 60, vertical motion of the vertical motion output terminal 26, horizontal The horizontal movement of the motion output 21 to the center of rotation 16 effects the operation of the group clamping mechanism 30 to grip the filling bottle 66 from the bottle feeding mechanism 60. The horizontal motion receiving end 31 and the vertical motion receiving end 36 of the group clamping mechanism 30 respectively receive the horizontal motion output and the vertical motion output of the orthogonal motion output indexing table 20, forming three consecutive groups of the group clamping mechanism 30. Movement action: horizontal movement of the group clamping mechanism 30 to the bottle feeding mechanism 60, vertical movement of the lifting plate 35 of the group clamping mechanism 30, horizontal movement of the group clamping mechanism 30 to the center of rotation 16 . When the group clamping mechanism 30 moves horizontally to the bottle feeding mechanism 60, the pressure bottle cover 33 is moved over the top of the filling bottle 66, and the two low backs 342 of the bottle holder 34 are moved below the bottle unloading plate 68. The high backrest 341 of the knob holder 34 is cut from the vial V-shaped opening 691; when the lifting plate 35 is moved vertically upward, the knob holder 34 and the support rod 347 pass through the special shape slit 686 on the guide bottle tray 68 to enter the guide bottle slot. 65. The filling bottle 66 is jacked up. During the jacking process, the top of the filling bottle 66 enters the pressure bottle cover 33. The double cantilever member 332 supplies positive pressure to the filling bottle 66 through the pressure bottle cover 33, and the filling bottle is filled. 66 clamping; group clamping mechanism 30 to the center of rotation 16 When moving horizontally, the support rod 347 placed on the lift plate 35 is withdrawn from the guide bottle slot 65 through the vial V-port 691.

After the above three consecutive movements, the movement path of the lifting plate 35 and the rotating bottle holder 34 placed thereon is a C-shaped curve. During the movement trajectory of the C-shaped curve, the filling bottle 66 is taken out from the guide bottle groove 65, and is firmly clamped by the pressure bottle cover 33 and the bottle holder 34 for subsequent orthogonal motion output. The indexing table 20 and the group clamping mechanism 30 are prepared for the rotation of the detecting station 1023 and the detection of liquid impurities in the bottle.

The high backrest 341 of the knob holder 34 has the effect of ensuring accurate positioning between the center of the bottle holder 34 and the center of the filling bottle 66: Due to the irregularity of the diameter of the filling bottle 66, the filling bottle 66 is The size of the projection of the V-shaped port 691 of the guide bottle will be different, and the center position of the filling bottle 66 in the front row and thereafter will also change. When the bottle holder 34 passes through the special shape notch 686 of the guide bottle holder 68 to lift the filling bottle 66, the two lower backs 342 of the bottle holder 34 may be filled with the second bottle in the slot of the guide bottle slot 65. The surface of the bottle 66 is scratched, and the second bottle 66 may be accidentally lifted. When the group clamping mechanism 30 and the needle holder 34 placed thereon are horizontally moved in the direction of the bottle feeding mechanism 60, the high back 341 of the bottle holder 34 is cut from the guide V-shaped opening 691, and the bottle holder is to be rotated. When the center of the first row of filling bottles 66 in the guide bottle slot 65 coincides with the center, the movement is terminated. When the high back 341 is cut from the V-shaped port 691 of the guide bottle, the upper portion of the high back 341 is in contact with the bottom outer edge of the first filling bottle 66 of the front row, and the first row of the front row having a small diameter and a large protrusion can be inserted. The bottling 66 pushes the return position to ensure accurate positioning between the center of the knob holder 34 and the center of the first row of filling bottles 66, while also pushing the second row of filling bottles 66 back into position. When the bottle holder 34 is lifted up from the first row of filling bottles 66, the two low backs 342 of the bottle holder 34 will not scratch the surface of the bottle of the second row of filling bottles 66, and There will be a phenomenon in which the second row of filling bottles 66 is mistakenly lifted. During the jacking process, the top of the filling bottle 66 enters the pressure bottle cover 33, and the top end of the pressure bottle cover 33 is designed as a conical surface, ensuring that the top of the filling bottle 66 enters the top of the filling bottle 66 after the pressure bottle cover 33 Automatic centering within the pressure bottle cap 33.

As shown in FIG. 3, the unloading plate 88 in the sorting mechanism 80 is provided with a plurality of parallel unloading plates 89, and the unloading plates 89 are spaced apart from each other and the unloading plate 88. Together, a plurality of parallel unloading tanks 85 are formed, and the group clamping mechanism 30 can simultaneously discharge each of the filling bottles 66 of the combination of the grouped filling bottles 66 to each of the unloading bottles. Inside the slot 85.

In the present embodiment, the unloading port 891 is a V-shaped port formed by two adjacent unloading and separating plates 89 on the inner side of the notch, that is, the unloading V-shaped port 891. The width of the unloading V-shaped port 891 is the same as the width of the V-shaped port 691 of the guide bottle, the diameter of the support rod 347 is also smaller than the width of the V-shaped opening 891 of the unloading bottle, and the support rod 347 in the upright state can pass through the V-shaped port of the unloading bottle. 891 enters the unloading tank 85.

In the present embodiment, the unloading opening 886 is opened in the unloading plate 85 in the unloading tank 85 for supporting the area of the filling bottle 66 discharged by the group clamping mechanism 30, that is, the special shape gap 886, the shape of the special shape gap 886 and The size and shape of the special shape notch 686 on the guide bottle holder 68 are exactly the same, and are also composed of two small trapezoidal notches 882 and one large rectangular notch 881, and the two small trapezoidal notches 882 also correspond to the revolving holder 34. Two low backrests 342, the large rectangular notch 881 is also a high backrest 341 corresponding to the bottle holder 34; in the notch of the unloading slot 85, two small trapezoidal notches 882 are also symmetrically distributed on both sides of the notch center line, large rectangle The notch 881 is also below the V-shaped opening and is the same width as the unloading V-shaped opening 891.

At the bottle unloading station 1040, the orthogonal motion output indexing table 20 is outputted by three consecutive motions: horizontal motion of the horizontal motion output 21 to the sorting mechanism 80, vertical motion of the vertical motion output 26 downward. The horizontal movement output end 21 moves horizontally to the swing center 16, and the operation of the group clamping mechanism 30 to discharge the filling bottle 66 into the unloading mechanism 80 is realized. The horizontal movement receiving end 31 and the vertical movement receiving end 36 of the group clamping mechanism 30 respectively receive the horizontal motion output and the vertical motion output of the orthogonal motion output indexing table 20, forming three consecutive ones of the group clamping mechanism 30. Movement action: horizontal movement of the grouping clamping mechanism 30 to the sorting mechanism 80, vertical downward movement of the lifting plate 35 of the group clamping mechanism 30, horizontal movement of the group clamping mechanism 30 to the center of rotation 16 . When the group clamping mechanism 30 moves horizontally to the unloading mechanism 80, the support rod 347 placed on the lifting plate 35 passes through the unloading V-shaped opening 891 into the unloading tank 85; when the lifting plate 35 moves vertically downward, The support rod 347 and the screw holder 34 pass through the special shape slit 886 on the unloading plate 88 to place the filling bottle 66 into the unloading tank 85. During the lowering process, the top of the filling bottle 66 is from the pressure bottle cover 33. Withdrawn, the filling bottle 66 is released from the state of being clamped by the pressure bottle cover 33 and the bottle holder 34; when the group clamping mechanism 30 is horizontally moved toward the center of rotation 16, the pressure bottle cover 33 is from the top of the filling bottle 66 The upper lower exit 342 and the high backrest 341 are respectively withdrawn from the lower part of the unloading plate 88 and the unloading V-shaped opening 891; after three consecutive movements, the filling bottle 66 It is released from the state of being clamped by the pressure bottle cover 33 and the bottle holder 34, and is placed in the notch of the unloading tank 85 to prepare for the sorting of the bottle discharging bottle of the subsequent sorting mechanism 80.

The sorting mechanism 80 is composed of a sorting cam 83, a sorting motor 838, a rack 84, a unloading tank 85, a bottle discharging lever 86, a bottle removing lever 87, and a bottle removing motor 878.

The unloading tank 85 of the sorting mechanism 80 is placed above the rack 84, and the rack 84 is placed on the sliding block of the horizontal linear bearing so as to be horizontally movable with respect to the rack platform. The pitch of the rack 84 is the same as the slot pitch of the unloading slot 85, and the bottle pull lever 86 and the pick-up lever 87 respectively correspond to the notches of two adjacent unloading slots 85, when the bottle is dialed When the rod 86 and the bottle removing lever 87 are rotated, the lever can be cut in from the unloading V-shaped port 891 of the unloading tank 85, and the filling bottle 66 in the notch is pushed out. Each time the sorting motor 838 is rotated, the sorting cam 83 pushes the rack 84 and the unloading tank 85 to move a notch. In the first half of one revolution cycle of the sorting cam 83, the sorting cam 83 has completed the action of pushing the rack 84 and the unloading tank 85 by one pitch; in the latter half of a swing working cycle, the sorting cam 83 The rack 84 is no longer moved, and the rack 84 and the unloading tank 85 are in a stationary state. In the first half of the cycle, the bottle pull lever 86 and the bottle pick-up lever 87 are in the push bottle In the preparation state of 66, in the second half cycle, when the rack 84 and the unloading tank 85 are in a stationary state, the bottle pull lever 86 or the bottle pick-up lever 87 pushes out the filling bottle 66 in the unloading tank 85, and dials The rod does not collide with the unloading tank 85. Each time the sorting cam 83 rotates, the bottle discharging lever 86 pushes the filling bottle 66 into the qualified finished box. When the number of rotations of the sorting cam 83 is the same as the number of slots of the unloading tank 85, the bottle pulling lever 86 can push all of the filling bottles 66 on the unloading tank 85 into the qualified finished box. If the liquid impurities in the bottle exceed the standard, the bottle removing lever 87 rejects the unqualified filling bottle 66 before the bottle discharging lever 86, and pushes it into the waste box.

It should be specially noted that the above device comprises one or several group clamping mechanisms 30 of the same structural size, and several group clamping mechanisms 30 of the same structural size are sequentially cycled and alternately operated for bottle taking. The initial station 1010, the inspection station 1023, and the bottle unloading station 1040 can improve the detection efficiency. The invention also discloses a method for detecting impurities contained in a bottled liquid by using the above device, and solves the technical problem that the detection rate of impurities in the existing bottled liquid is low and the adaptability is poor. The method of the invention is as follows:

Step 3: At the bottle unloading station 1040, the detected group of filling bottles 66 are discharged into the sorting mechanism 80; Step 4, the sorting mechanism 80 of the bottle unloading station 1040 will be step 2 The selected unqualified filling bottle 66 is removed. Specifically, in step 1, at the initial bottle dispensing station 1010 of the bottle feeding mechanism 60, the group clamping mechanism 30 grips the filling bottle in groups, that is, the group clamping mechanism 30 from the bottle feeding mechanism In the plurality of guide flasks 65 of 60, the first row of filling bottles 66 in the front row of each of the guide bottle slots 65 are simultaneously taken out at a time, forming a group of simultaneous moving, simultaneous detection, and simultaneous unloading of the bottles. The combination of the bottling 66; then, in step 2, the combination of the group clamping mechanism 30 and the filling bottle 66 to be tested is rotated along with the orthogonal motion output indexing table 20 to be equipped with The detecting station 1023 of the lighting system 70 performs a spin-on bottle control operation on the group of filling bottles 66, and simultaneously detects the contents of the group of filling bottles 66. SP: enables the group of filling bottles 66 to rotate at the same time at high speed. The liquid rotary motion drives the precipitated impurities in the liquid to rise, and the backlight 71 directly illuminates the filling bottle 66 or the bottom illumination 76 to illuminate the filling bottle 66 through the through hole in the hollow support rod 347, and is electrically connected to the computer analysis control system 90. The camera 51 of the connected image acquisition system 50 captures the liquid rotation state After the impurity has popped up the sequence image, the computer analyzes it and calculates the size of the insoluble impurity particles to determine whether it exceeds the standard. When the station 1023 has two or more inspection stations, the simultaneous movement of a group of filling bottles also includes the movement between different stations within the inspection station 1023, and the simultaneous detection of a group of filling bottles also includes all detections. Simultaneous detection of the station, the combination of the group clamping mechanism 30 and the detected filling bottle 66 is rotated along with the orthogonal motion output indexing table 20 to the decanting bottle station 1040. Step 3: At the bottle unloading station 1040 of the sorting mechanism 80, the group clamping mechanism 30 unloads the filling bottle 66 in groups, BP: the group clamping mechanism 30 simultaneously clamps the bottle The plurality of tested filling bottles 66 are placed in a plurality of juxtaposition unloading tanks 85 in the sorting mechanism 80; Step 4, in the decanting bottle unloading station 1040, the decanting of the sorting mechanism 80 The bottle sorting work is carried out independently, SP: the sorting mechanism 80 takes the unqualified filling bottle 66 and removes the bottle picking out of the bottle sorting work, and the group clamping mechanism 30 takes the bottle feeding mechanism 60 The rotary reset of the initial station 1010, the take-up from the bottle feeding mechanism 60 at the initial dispensing station 1010, and the initial work of taking the bottle The bit 1010 is moved to the detection station 1023, and the detection at the detection station 1023 is sequentially performed in synchronization.

The method comprises one or several group clamping mechanisms 30 of the same structural size, and several group clamping mechanisms 30 of the same structural size are sequentially cycled and alternately operated at the initial bottle taking station 1010. The detection station 1023 and the bottle unloading station 1040 can improve the detection efficiency.

Specifically, the step of implementing a detection duty cycle of the embodiment of the present invention is constituted by the operation of the group clamping mechanism 30 at different working positions of the following stations and the movement between the stations, and the following is a detailed description of the method. It is also a description of the work of the aforementioned device:

• Step 1, the working state of the group clamping mechanism 30 at the initial bottletting station 1010 of the bottle feeding mechanism 60: After adjusting the positioning direction of the bottle holder 34, the group clamping mechanism 30 moves until the bottle holder 34 The center coincides with the center of the filling bottle 66 to be gripped, and the filling bottle 66 is jacked up in a group and taken out for preparation for subsequent detection. In the initial state of the initial bottletting station 1010 of the bottle feeding mechanism 60, the group clamping mechanism 30 is at the initial position of its minimum radius of gyration, and the level of the top ends of the two lower backrests 342 of the bottle holder 34 is lower than the guide bottle. The bottom edge of the plate 68 and the pressure bottle cover 33 is higher than the top end of the filling bottle 66.

First, the positioning direction of the knob holder 34 is adjusted by the rotary bottle motor 348 and the angle sensor 349 in the group clamping mechanism 30, and the center of the two low backrests 342 of the knob holder 34 and the center and movement of the high backrest 341 are adjusted. The directions are the same, and the two low backs 342 are on the outside and the high back 341 is on the inside. After adjusting the direction of the backrest of the knob holder 34, the orthogonal motion output indexing table 20 outputs a horizontal motion to the bottle feeding mechanism 60, and the horizontal motion output end 21 of the orthogonal motion output indexing table 20 passes through the group clamping mechanism 30. The horizontal movement receiving end 31 drives the group clamping mechanism 30 to move, and the group clamping mechanism 30 performs corresponding synchronous horizontal movement from the initial position of the minimum radius of gyration to the bottle feeding mechanism 60; the pressure bottle cover 33 is moved to Above the top of the filling bottle 66, the two lower backs 342 of the bottle holder 34 are moved below the guide bottle tray 68, and the high back 341 is cut from the V-shaped port 691 of the guide bottle; the center of the bottle holder 34 and the guide bottle are to be opened In the middle of the first row of filling bottles 66 in the tank 65 When the hearts coincide, the horizontal motion output of the orthogonal motion output indexing table 20 to the bottle feeding mechanism 60 is terminated.

Then, the orthogonal motion output indexing table 20 outputs an upward vertical motion, and the vertical motion output end 26 of the orthogonal motion output indexing table 20 drives the lifting plate 35 vertically upward through the vertical motion receiving end 36 of the group clamping mechanism 30. Moving, the plurality of knob holders 34 and the support rods 347 on the lifting plate 35 are also moved upward in synchronization. The guide bottle tray 68 below the first row of filling bottles 66 in the guide bottle slot 65 has a special shape slit 686, because of the distribution position of the three backrests of the bottle holder 34 and the special shape gap 686 The distribution positions of the notches correspond to each other, and the size of each backrest is smaller than the corresponding gap size. The bottle holder 34 and the support rod 347 can pass through the special shape gap 686 and pass through the guide bottle holder 68 to enter the corresponding position. In the guide bottle tank 65, the filling bottle 66 to be gripped in the guide bottle groove 65 is lifted up, and a plurality of jacked filling bottles 66 are clamped by the pressure bottle cover 33 and the bottle holder 34 to form a group. A combination of filling bottles 66 to be tested. When the group clamping mechanism 30 and the upper bottle holder 34 are horizontally moved in the direction of the bottle feeding mechanism 60, the high back 341 of the bottle holder 34 is cut from the V-shaped port 691 of the guide bottle, and can be guided. The front-end filling bottle 66 having a small diameter and a large diameter at the V-shaped port 691 of the bottle groove 65 is pushed back to ensure that the bottle holder 34 accurately pushes up the first bottle 66 of the front row. The screw holder 34 lifts the filling bottle 66 during the lifting process, since the orientation of the two low backs 342, the high back 341, and the accurate positioning between the bottle holder 34 and the filling bottle 66 are ensured, the bottle is rotated. The two low backrests 342 on the seat 34 do not scratch the front and rear filling bottles 66, and do not scratch the surface of the bottle, nor do they cause the second row of filling bottles 66 to be mistaken. During the process of filling the filling bottle 66, the top of the filling bottle 66 enters the pressure bottle cover 33; the top end of the pressure bottle cover 33 and the inner bottom surface of the round table of the round bottle holder 34 are all conical surfaces, ensuring the top of the filling bottle 66 Within the pressure bottle cap 33, the bottom of the filling bottle 66 is self-centering within the bottle holder 34. The unique design of the inner surface of the pressure bottle cap 33 and the conical surface of the inner bottom surface of the round table 34 and the positive pressure provided by the double cantilever member 332 to the filling bottle 66 through the pressure bottle cap 33 ensures the filling of the bottle The automatic centering of 66 can also clamp the filling bottle 66 firmly. After the bottom edge of the round table of the bottle holder 34 exceeds the height of the vial partition 69, the vertical motion output of the orthogonal motion output indexing table 20 is terminated.

Finally, the orthogonal motion output indexing table 20 outputs a horizontal motion to the swing center 16, and the horizontal motion output end 21 of the orthogonal motion output indexing table 20 is driven by the horizontal motion receiving end 31 of the group clamping mechanism 30. The clamping mechanism 30 moves again, and the group clamping mechanism 30 performs corresponding synchronous horizontal movement to the rotation center 16; when the filling bottle 66 is in the clamping state, the bottom edge of the round table 34 is higher than the guide bottle isolation plate 69. The height of the support rod 347 is smaller than the width of the V-shaped port 691 of the guide bottle, and the support rod 347 can be withdrawn from the guide bottle slot 65 through the V-shaped port 691 of the guide bottle; the clamping mechanism 30 to be returned to its minimum radius of gyration At the initial position, the horizontal motion output of the orthogonal motion output indexing table 20 to the center of revolution 16 is terminated.

The orthogonal motion output indexing table 20 passes through the above three motion outputs: horizontal movement to the bottle feeding mechanism 60, upward vertical movement, horizontal movement to the swing center 16, lifting plate 35, and a rotary cup holder placed thereon The movement track of 34 is one Strip C curve. During the movement of the C-curve, the combination of the filling bottles 66 is lifted, clamped out, and clamped firmly, ready for subsequent movement to the inspection station 1023.

• Step 2, check the working status of the station 1023, the movement of the inspection station 1023 and the previous station, the movement between different stations within the inspection station 1023, and the movement between the inspection station 1023 and the next station; The bit 1023 includes a backlight detection station 1020 and a base illumination and black background detection station 1030. Therefore, the method specifically includes: 1 combination of the group clamping mechanism 30 and the filling bottle 66 clamped thereto from the bottle feeding mechanism 60 The initial bottle taking station 1010 is moved to the backlight detecting station 1020, 2 for detection at the backlight detecting station 1020, and the combination of the 3-group clamping mechanism 30 and the filling bottle 66 held by the backlight is from the backlight. The detection station 1020 moves to the bottom illumination and black background detection stations 1030, 4 for detection at the bottom illumination and black background detection station 1030, and the combination of the 5-group clamping mechanism 30 and the filling bottle 66 it holds. Moving from the bottom illumination and black background inspection station 1030 to the decantering station 1040.

1 The combination of the group clamping mechanism 30 and the filling bottle 66 it holds is moved from the initial bottle dispensing station 1010 of the bottle feeding mechanism 60 to the backlight detecting station 1020: the group clamping mechanism 30 and its The combination of the clamped fill bottles 66 and the camera 51 placed over the set of gripping mechanisms 30 are indexed with the orthogonal motion output indexing table 20 to be equipped with a backlight detection station 1020. When the orthogonal motion output indexing table 20 rotates toward the backlight detecting station 1020, the orthogonal motion output indexing table 20 and the group clamping mechanism 30 placed thereon are at the initial position of the minimum radius of gyration, in a group The portion of the maximum radius of gyration of the outer left and right ends of the gripping mechanism 30 does not collide with the front end of the guide bottle groove 65 of the bottle feeding mechanism 60 and the backlight 71.

2 Detection is performed at the backlight detecting station 1020: The group clamping mechanism 30 is at the backlight detecting station 1020, and the backlight 71 and the camera 51 are respectively placed on both sides of the filling bottle 66. The optical axis of the camera corresponding to each set of filling bottles 66 is perpendicular to its corresponding backlight 71.

The orthogonal motion output indexing table 20 outputs a horizontal motion to the backlight 71, and the combination of the group clamping mechanism 30 and the filling bottle 66 to be tested is also made to the corresponding back from the initial position of the minimum radius of gyration. The synchronous movement of the light source 71 is horizontally moved, and the combination of the filling bottles 66 to be tested held by the group clamping mechanism 30 approaches the backlight 71. When the camera can clearly capture the contents of the filling bottle 66, the orthogonality is terminated. The motion output indexing table 20 outputs a horizontal motion to the backlight 71.

In the static state, the liquid impurities in the filling bottle 66 are usually at the bottom of the bottle, and it is difficult to detect these impurities. The liquid in the filling bottle 66 is rotated, and the impurities float away from the bottom of the bottle as the liquid in the bottle rotates, so that the presence of impurities can be clearly observed.

Because the double cantilever member 332 can provide a certain positive pressure to the filling bottle 66 through the pressure bottle cap 33, it can be ensured that there is no relative sliding between the two when the bottle holder 34 drives the filling bottle 66 to rotate. Rotary bottle motor 348 rotary drive When the acceleration is accelerated, the bottle holder 34 drives the pressure bottle cover 33 and the filling bottle 66 to rotate synchronously, and the liquid in the filling bottle 66 follows the filling bottle 66 to rotate in the same direction, and the liquid rotating motion drives the various deposits in the bottle. The impurities floated one after another.

The backlight 71 directly illuminates the filling bottle 66. Under the illumination of the white backlight 71, the camera 51 can clearly capture the suspended black impurity particles which are generated in the liquid.

The camera 51 respectively captures a sequence moving image in which the impurities of different specific gravity in the rotating liquid in the respective groups of the filling bottles 66 are successively floated, and the computer analysis control system 90 analyzes the captured image.

After the sequence moving image is taken, the orthogonal motion output indexing table 20 outputs a horizontal motion to the swing center 16, and the horizontal motion output end 21 of the orthogonal motion output indexing table 20 passes through the horizontal motion receiving end 31 of the group clamping mechanism 30. The group clamping mechanism 30 is driven to move again, and when the combination of the group clamping mechanism 30 and the filling bottle 66 clamped thereto returns to the initial position of the minimum radius of gyration, the orthogonal motion output indexing table 20 is terminated. The horizontal motion output to the center of revolution 16 is output.

3 The combination of the group clamping mechanism 30 and the filling bottle 66 it holds is moved from the backlight detecting station 1020 to the bottom illumination and black background detecting station 1030: the group clamping mechanism 30 is clamped thereto The combination of the filling bottles 66 and the camera 51 placed on the group clamping mechanism 30 are indexed to the bottom illumination and black background stations along with the orthogonal motion output indexing table 20. When the orthogonal motion output indexing table 20 rotates toward the bottom illumination and black background detecting station 1030, the orthogonal motion output indexing table 20 and the group clamping mechanism 30 placed thereon are at the initial position of the minimum radius of gyration. The portion of the maximum radius of gyration of the outer left and right ends of the group clamping mechanism 30 does not collide with the backlight 71 and the black background 77.

4 In the bottom illumination and black background detection station 1030 for detection: the group clamping mechanism 30 in the bottom illumination and black background detection station 1030, the bottom illumination 76 and the black background 77, the camera 51 are placed in the filling bottle 66 respectively side. The optical axis of the camera corresponding to each set of filling bottles 66 is perpendicular to its corresponding black background 77. However, at this time, the centers of the screw holder 34 and the filling bottle 66 on the group clamping mechanism 30 are not at the center of the bottom illumination 76. The orthogonal motion output indexing table 20 outputs horizontal motion to the bottom illumination 76 and the black background 77, and the combination of the group clamping mechanism 30 and the filling bottle 66 to be tested is also from the initial position of the minimum radius of gyration. The corresponding horizontal movement of the bottom illumination 76 and the black background 77 is started. When the center of the bottle holder 34 and the filling bottle 66 on the group clamping mechanism 30 coincides with the center of the bottom illumination 76, the orthogonal motion is terminated. The output indexing table 20 outputs horizontal motion to the bottom illumination 76 and the black background 77.

The illuminating light 76 illuminates the filling bottle 66 through a through hole in the rod of the hollow support rod 347. In the state of the illumination from the bottom to the top and the black background, the camera 51 can clearly capture the suspended white impurity particles which are generated in the liquid. The detection principle of the backlight detecting station 1020 is the same as that: when the rotary bottle motor 348 is rotationally driven to accelerate, the bottle holder 34 drives the pressure bottle cover 33 and the filling bottle 66 to rotate synchronously, and the liquid in the filling bottle 66 follows the filling. The bottle 66 performs the same direction of rotation, and the liquid rotary motion drives the various impurities deposited in the bottle to float one after another.

After the sequence moving image is taken, the orthogonal motion output indexing table 20 outputs a horizontal motion to the swing center 16, and the horizontal motion output end 21 of the orthogonal motion output indexing table 20 passes through the horizontal motion receiving end 31 of the group clamping mechanism 30. The group clamping mechanism 30 is driven to move again, and when the combination of the group clamping mechanism 30 and the filling bottle 66 clamped thereto returns to the initial position of the minimum radius of gyration, the orthogonal motion output indexing table 20 is terminated. To the center of rotation

16 horizontal motion output.

5 The combination of the group clamping mechanism 30 and the filling bottle 66 it holds is moved from the bottom illumination and black background detection station 1030 to the decantering station 1040: the group clamping mechanism 30 is clamped thereto The combination of the holding bottles 66 and the camera 51 placed on the group clamping mechanism 30 are rotated along with the orthogonal motion output indexing table 20 to the decanting station 1040 of the sorting mechanism 80. . When the orthogonal motion output indexing table 20 rotates toward the decanting bottle unloading station 1040 of the sorting mechanism 80, the orthogonal motion output indexing table 20 and the group clamping mechanism 30 placed thereon are at the minimum radius of gyration The initial position, the portion of the maximum radius of gyration of the outer left and right ends of the group clamping mechanism 30 does not collide with the black background 77 and the front end of the unloading tank 85 of the sorting mechanism 80.

• Step 3, the group clamping mechanism 30 is in the working state of the bottle unloading station 1040 of the sorting mechanism 80 and the initial setting of the bottle unloading station 1010 to the bottle feeding mechanism 60: adjusting the positioning of the bottle holder 34 After the direction, the group clamping mechanism 30 moves until the center of the bottle holder 34 coincides with the center of the discharge filling bottle 66 in the unloading tank 85, and at the same time, the plurality of filled bottles that are clamped and tested The combination of 66 is discharged into a plurality of juxtaposition unloading tanks 85 in the sorting mechanism 80, and is swung back to the initial dispensing station 1010 of the bottle feeding mechanism 60.

In the initial state of the bottle unloading station 1040 of the sorting mechanism 80, the group clamping mechanism 30 is at the initial position of its minimum radius of gyration, and the bottom edge of the cup holder 34 is higher than the bottle unloading plate. 89.

First, the positioning direction of the knob holder 34 is adjusted by the rotary bottle motor 348 and the angle sensor 349 in the group clamping mechanism 30, and the center of the two low backrests 342 of the knob holder 34 and the center and movement of the high backrest 341 are adjusted. The directions are the same, and the two low backs 342 are on the outside and the high back 341 is on the inside. After adjusting the direction of the backrest of the knob holder 34, the orthogonal motion output indexing table 20 outputs a horizontal motion to the sorting mechanism 80, and the horizontal motion output end 21 of the orthogonal motion output indexing table 20 passes through the group clamping mechanism 30. The horizontal movement receiving end 31 drives the group clamping mechanism 30 to move, and the group clamping mechanism 30 performs corresponding synchronous horizontal movement from the initial position of the minimum radius of gyration to the sorting mechanism 80; the filling bottle 66 When in the clamping state, the bottom edge of the round table 34 is higher than the unloading plate 89, and the diameter of the support rod 347 is smaller than the width of the unloading V-mouth 891, and the support rod 347 can enter through the unloading V-port 891. In the unloading tank 85; when the center of the support rod 347 and the screw holder 34 is moved to the center position of the discharge bottle 66 in the unloading tank 85, the orthogonal motion output indexing table 20 is terminated to the sorting mechanism 80. Horizontal motion output.

Then, the orthogonal motion output indexing table 20 outputs a downward vertical motion, and the vertical motion output end 26 of the orthogonal motion output indexing table 20 drives the lifting plate 35 vertically through the vertical motion receiving end 36 of the group clamping mechanism 30. Moving downward, the plurality of knob holders 34 and the support rods 347 on the lift plate 35 also move downward in synchronization. The unloading plate 88 below the unloading bottle 66 in the unloading tank 85 is provided with a special shape slit 886, because of the distribution of the three backrests of the bottle holder 34 and the distribution of the three notches of the special shape gap 886 Corresponding positions, and the size of each backrest is smaller than the corresponding gap size, and the bottle holder 34 and the support rod 347 can exit the unloading tank 85 through the special shape gap 886, and the combination of the detected filling bottles 66 is It is released in a state of being sandwiched by the plurality of pressure bottle caps 33 and the bottle holder 34, and is discharged into a plurality of juxtaposition unloading tanks 85.

Finally, the orthogonal motion output indexing table 20 outputs a horizontal motion to the swing center 16, and the horizontal motion output end 21 of the orthogonal motion output indexing table 20 is driven by the horizontal motion receiving end 31 of the group clamping mechanism 30. The clamping mechanism 30 moves again, and the group clamping mechanism 30 makes a corresponding synchronous horizontal movement to the swing center 16; the high back 341 is withdrawn through the unloading V-shaped opening 891, and the pressure bottle cover 33 is withdrawn from the top of the filling bottle 66. , the bottle holder 34 is withdrawn from the lower side of the unloading tank 85. After the filling bottle 66 is released, the height of the bottom edge of the pressure bottle cover 33 is higher than the top end of the filling bottle 66, and the two low backs 342 of the bottle holder 34 are unloaded. Below the bottle holder 88, when the group clamping mechanism 30 moves horizontally to the center of rotation 16, the pressure bottle cover 33 and the backrest of the bottle holder 34 do not scratch with the filling bottle 66 and the sorting mechanism 80. When the group clamping mechanism 30 returns to the initial position of its minimum radius of gyration, the horizontal motion output of the orthogonal motion output indexing table 20 to the swing center 16 is terminated, which is the subsequent rotation to the initial bottle taking station 1010. Reset well Equipment.

The orthogonal motion output indexing table 20 passes through the above three motion outputs: a combination of the detected filling bottles 66 during the horizontal movement to the sorting mechanism 80, the downward vertical motion, and the horizontal motion to the swing center 16. Released from the state sandwiched by the plurality of pressure bottle caps 33 and the screw holders 34, they are discharged into a plurality of juxtaposition unloading tanks 85 for sorting the bottles of the subsequent sorting mechanism 80. be ready.

After the filling bottle 66 is removed, the sorting mechanism 80 picks up the bottle and sorts the bottle, and the orthogonal motion output indexing table 20 swings and resets to the bottle initial station 1010 of the bottle feeding mechanism 60, and the group clamp The holding mechanism 30 and the camera 51 placed thereon are also pivotally reset from the bottle unloading station 1040 to the initial bottle dispensing station 1010 of the bottle feeding mechanism 60 to prepare for the next inspection cycle.

When the orthogonal motion output indexing table 20 is pivotally reset to the initial bottletting station 1010 of the bottle feeding mechanism 60, the orthogonal motion output indexing table 20 and the group clamping mechanism 30 placed thereon are at the minimum radius of gyration. Initial position, grouped gripper The portion of the outermost right and left ends of the structure 30 that does not have the maximum radius of gyration does not collide with the front end of the unloading tank 85, the black background 77, the backlight 71, and the leading end of the guide bottle groove 65. When the orthogonal motion output indexing table 20 is rotated, the group clamping mechanism 30 and the camera 51 are synchronously swiveled and reset.

• Step 4. The sorting mechanism of the bottle unloading station 1040 rejects the unqualified filling bottles selected in step 3, and the sorting mechanism 80 sorting work is carried out independently:

In the bottle unloading station 1040 of the sorting mechanism 80, the sorting out of the bottle sorting mechanism 80 is carried out independently, that is, the sorting mechanism 80 removes the bottle from the unqualified filling bottle 66. At the same time as the bottle sorting work is performed, the group clamping mechanism 30 resets the rotation of the bottle initial station 1010 of the bottle feeding mechanism 60, and takes the bottle from the bottle feeding mechanism 60 at the initial bottle taking station 1010. The initial station 1010 is moved to the inspection station 1023, and the detection at the inspection station 1023 is performed simultaneously.

After two stations detection of backlight detection, bottom illumination and black background, the camera 51 clearly captures a sequence moving image of black and white impurity particles suspended in the filling bottle 66. The camera 51 is electrically connected to the computer analysis control system 90, and the computer performs characteristic analysis on the sequence image captured by the camera 51 to calculate the size of the insoluble impurity particles. According to the size of the particles, it can be determined whether the impurity particles exceed the standard, it is determined whether the filling bottle 66 is qualified, and the detection result of the filling bottle 66 is recorded.

The bottle discharging lever 86 and the bottle removing lever 87 of the sorting mechanism 80 respectively correspond to the notches of two adjacent unloading tanks 85. When the bottle discharging lever 86 and the bottle removing lever 87 are rotated, the lever The bottle unloading V-shaped port 891 of the unloading tank 85 can be cut in, and the filling bottle 66 in the notch can be pushed out.

During the sorting process of the sorting mechanism 80, the sorting motor 838 rotates one cycle per revolution, and the sorting cam 83 pushes the rack 84 and the unloading tank 85 placed thereon to move a notch, and at the same time, the sorting motor 838 also The bottle-out lever 86 is driven to rotate, and the filling bottle 66 in the corresponding slot is pushed into the qualified finished box.

In the first half cycle, the bottle pull lever 86 and the bottle pick-up lever 87 are in a ready state for pushing out the filling bottle 66. In the second half cycle, when the rack 84 and the unloading tank 85 are in a stationary state, the bottle pull lever 86 or The bottle removing lever 87 pushes out the filling bottle 66 in the unloading tank 85, and the lever does not collide with the unloading tank 85.

When the filling bottle 66 carried by the unloading tank 85 is recorded as a defective product, and the notch of the unqualified filling bottle 66 corresponds to the notch of the waste box, the computer controls the bottle removing motor 878 to drive the decanting lever 87 Rotating, the unqualified filling bottle 66 is pushed into the waste bin to realize the sorting of the filling bottle 66 which removes the impurity particles. The bottle removing lever 87 rejects the unqualified filling bottle 66 before the bottle discharging lever 86, and pushes it into the waste box. In the next rotation working cycle of the sorting cam 83, the bottle discharging lever 86 is only a free-wheeling rotation. , does not introduce any filling bottle 66. The sorting motor 838 drives the number of revolutions of the sorting cam 83 and When the number of the notches of the unloading tank 85 is the same, the bottle discharging lever 86 can push all the filling bottles 66 on the unloading tank 85 after the unqualified filling bottle 66 is removed into the qualified finished box. In summary, the apparatus and method for detecting liquid impurities in a group-type filling bottle are subjected to the above-mentioned bottle taking, rotation indexing, detecting, re-rotation indexing, re-detection, re-rotation indexing, unloading, and rotary resetting. The combination of working states is implemented.
