Description

Technical Field

[0002] After Chinese patent medicine is concentrated and made into pill granules or capsules, it needs to be filled into medicine bottles according to a set quantity, and then the bottle cap is tightened on the bottle mouth of the medicine bottle body through a bottle cap tightening device. The inner lining of the bottle cap has an aluminum film, and then the electromagnetic induction heating plate of the aluminum film sealing machine instantaneously heats the aluminum film in the medicine bottle at a high temperature to seal the bottle mouth of the medicine bottle with the aluminum film.

[0003] If there is a phenomenon that the bottle cap is twisted or not tightened in place in the medicine bottles output by the bottle cap tightening device, the medicine bottles with twisted or not tightened bottle caps are mixed with the medicine bottles with tightened bottle caps and pass through the aluminum film sealing machine in sequence. Since the aluminum film in the medicine bottles with twisted or not tightened bottle caps cannot completely adhere to the bottle mouth, after the medicine bottles with twisted or not tightened bottle caps are heated by the electromagnetic induction heating plate, it will cause the aluminum film in some medicine bottles to not completely seal the bottle mouth, which will affect the quality of the finished medicine output by the medicine bottle packaging line.

[0064] One end of the height limiting cross bar 3231 extends in a direction perpendicular to the running direction of the conveyor belt 10, the other end of the height limiting cross bar 3231 is connected to the upper end of the vertical rod 3232, and the lower end of the vertical rod 3232 is installed on one side of the conveyor belt 10; the electromagnetic induction heating plate 312 is located in front of the running direction of the height limiting cross bar 3231;

[0065] The guiding groove 2421 is used to input the bottle caps 60 output from the bottle cap output end 221; the height limiting cross bar 3231 is used to block the medicine bottles with the bottle caps screwed crooked or not screwed in place.

[0066] Figure 1Schematic structural diagram of an embodiment of a cap tightening mechanism 2 of a medicine bottle packaging line of the present utility model. Figure 6 is Figure 1 an enlarged view of part A of Figure 6 which shows the installation structure of the cap screwing device 24. Figure 1 In , the conveyor belt 10 runs from back to front. The conveyor belt 10 is provided with a cap tightening station 100. The cap tightening device 23 located at the cap tightening station 100 includes a plurality of cap tightening heads 231. Claw jaws for clamping the cap 60 are provided inside the cap tightening heads 231. A gap between two endless belts 211 forms a bottle body conveying channel 210. The mouth part of the bottle body 61 in the bottle body conveying channel 210 is exposed upward outside the top surface of the two endless belts 211. The output port of the cap conveying device 22 is located above the bottle body conveying channel 210 and close to the input end of the bottle body conveying channel 210. The cap tightening device 23 is located above the bottle body conveying channel 210 and close to the output end of the bottle body conveying channel 210.

[0067] Figure 2 Schematic structural diagram of an embodiment of an aluminum mold sealing device 3 of the present utility model. Figure 5 Schematic installation structure diagram of the limit rod 323 in the aluminum film sealing device 3.

[0068] Figure 2 The aluminum film sealing device 3 in includes an aluminum film sealer 31. The conveyor belt 10 is further provided with a sealing station 101. The aluminum film sealer 31 located at the sealing station 101 includes an electromagnetic induction heating plate 312. The electromagnetic induction heating plate 312 is mounted directly above the conveyor belt 10 and extends along the running direction of the conveyor belt 10.

[0069] It should be noted that: the cap tightening device 24 is used to tighten the cap 60. Among the medicine bottles output by the cap tightening device 24, there are some medicine bottles with the caps screwed crookedly or the caps not tightened in place. The top surface of the medicine bottles with the caps screwed crookedly or not tightened in place is higher than the top surface of the medicine bottles with the caps tightened in place.

[0070] If the medicine bottles with the caps screwed crookedly or not tightened in place are mixed with the medicine bottles with the caps tightened in place and sequentially pass through the limit channel 3210 and are instantaneously heated at a high temperature by the electromagnetic induction heating plate 312, the aluminum film in the medicine bottles may be partially skewed. Therefore, the aluminum film in some medicine bottles may not completely seal the bottle mouth.

[0071] such as Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the bottle caps 60 are output one by one from the bottle cap output end 221 of the bottle cap conveying device 22 and enter the opening end 24211 of the guiding groove 2421. At the same time, the bottle bodies 61 are conveyed one by one through the conveyor belt 10 and enter the bottle body conveying channel 210 between the two endless belts 211. The two sides of the bottle body 61 are respectively abutted against the two belt conveying surfaces of the two endless belts 211 located on both sides of the bottle body conveying channel 210. When a bottle body 61 reaches below the guiding groove 2421, a corresponding bottle cap 60 falls onto the top of the bottle mouth of the bottle body 61 through the guiding groove 2421. The two side groove walls of the guiding groove 2421 can limit the left - right movement of the bottle cap 60, and the bottom surface of the rear - end groove wall of the guiding groove 2421 can correct the flatness of the top surface of the bottle cap 60. In this way, the proportion of deviation and skew of the bottle caps 60 of the medicine bottles output by the bottle cap tightening mechanism 2 can be reduced. Then, before the medicine bottles are transported by the conveyor belt 10 to the lower part of the electromagnetic induction heating plate 312 of the aluminum film sealing machine 31, the height - limiting cross bar 3231 blocks the medicine bottles with the bottle caps being twisted or not tightened in place, and the medicine bottles with the bottle caps being twisted or not tightened in place on the conveyor belt 10 are removed in time by a manipulator or manually.

[0072] Further, the bottle cap screwing device 24 further includes a bottle cap guiding plate 242;

[0073] The friction plate 243 is located in front of the running direction of the guiding groove 2421, and the bottom edge of the friction plate 243 faces downward and approaches the bottle body conveying channel 210; the wall surface of the groove wall of the guiding groove 2421 and the plate surface of the friction plate 243 are both parallel to the belt conveying surface of the endless belt 211 located in the bottle body conveying channel 210;

[0074] The friction plate 243 is used to friction with the outer peripheral surface of the bottle cap 60 moving in the bottle body conveying channel 210.

[0075] As Figure 1 and Figure 6 As shown, when the bottle body 61 with the bottle cap 60 on the bottle mouth continues to move along the bottle body conveying channel 210 under the clamping and driving of the two endless belts 211, the friction plate 243 frictions with the outer peripheral surface of each passing bottle cap 60, causing the bottle cap 60 to rotate and screwing the internal thread of the bottle cap 60 into the external thread of the corresponding bottle mouth of the bottle body 61. When the bottle body 61 reaches below the bottle cap tightening device 23, the bottle cap tightening head 231 in the bottle cap tightening device 23 extends downward to clamp the bottle cap with the jaws, and then the bottle cap tightening head 2311 rotates the jaws and tightens the internal thread of the bottle cap 60 onto the external thread of the bottle mouth, which can reduce the working load of the bottle cap tightening device 23 and improve the production efficiency of the medicine bottle packaging line.

[0076] Further, the bottle cap guiding plate 242 further includes an extension plate 2422 and a guiding inclined plate 2423;

[0077] The extension plate 2422 extends in the horizontal direction. The rear end of the extension plate 2422 is connected to the front bottom edge of the guiding groove 2421, and the front end of the extension plate 2422 extends forward along the bottle body conveying channel 210.

[0078] The front end of the friction plate 243 is flush with the front end of the extension plate 2422, and the rear end of the friction plate 243 is located in front of the rear end of the extension plate 2422.

[0079] The bottom edge of the guiding inclined plate 2423 is connected to the rear side of the guiding groove 2421 at the open end 24211, and the plate surface of the guiding inclined plate 2423 extends backward and upward.

[0080] As Figure 6 shown, before the friction plate 243 comes into frictional contact with the side surface of the bottle cap 60, the top surface of the bottle cap 60 is blocked from moving upward by the rear end portion of the extension plate 2422, and the flatness of the top surface of the bottle cap 60 is corrected, thereby improving the effectiveness of screwing the bottle cap 60 into the thread on the outer peripheral surface of the bottle mouth of the corresponding bottle body 61 during rotation.

[0081] As Figure 1 and Figure 6 shown, before the bottle cap 60 output from the bottle cap output end 221 of the bottle cap conveying device 22 enters the open end 24211 of the guiding groove 2421, the front top of the bottle cap 60 contacts the plate surface of the guiding inclined plate 2423 that extends backward and upward. The bottle cap 60 enters the guiding groove 2421 along the guidance of the guiding inclined plate 2423. After entering the guiding groove 2421, the front end of the bottle cap 60 inclines downward, so that the front bottom of the bottle cap 60 contacts the outer peripheral surface of the front top of the bottle mouth of the bottle body 61 passing by from the front and below. When the corresponding bottle body 61 continues to move forward, it drives the bottle cap 60 to move, and enables the bottle cap 60 to accurately fit over the top of the bottle mouth of the bottle body 61. Then, the flatness of the bottle cap 60 located at the top of the bottle mouth is corrected by the rear end portion of the extension plate 2422, so that the inclined top surface of the bottle cap is restored to a horizontal plane, and then the bottle cap 60 is rotated by the friction plate 243. In this way, the effectiveness of screwing the internal thread of the bottle cap 60 into the external thread of the bottle mouth of the corresponding bottle body 61 can be further improved.

[0082] In a preferred embodiment, the plate surface of the guiding inclined plate 2423 is an arc-shaped plate surface that extends backward and upward.

[0083] Most of the top circular edges of the bottle caps 60 of medicine bottles have arc-shaped chamfers. The setting that the plate surface of the guiding inclined plate 2423 is an arc-shaped plate surface that extends backward and upward can improve the smoothness of guiding the bottle cap 60 into the guiding groove 2421 obliquely by the guiding inclined plate 2423.

[0084] Furthermore, the bottle cap screwing device 24 further includes a lifter 244 and a mounting bracket 241;

[0085] The lifter 244 is hung above the bottle conveying channel 210, the output end of the lifter 244 faces downward, and the top surface of the bottle cap guiding plate 242 is connected to the output end of the lifter 244;

[0086] The friction plate 243 is further provided with a connecting piece 2431; the connecting piece 2431 is provided with at least two opening grooves 24311;

[0087] One side of the connecting piece 2431 is connected to the middle of the top edge of the friction plate 243, and the other side of the connecting piece 2431 extends horizontally away from the bottle conveying channel 210;

[0088] The mounting frame 241 is mounted above the machine table 1, and the top surface of the mounting frame 241 is located above the top surface of the bottle conveying channel 210;

[0089] The opening groove 24311 penetrates the connecting piece 2431 from top to bottom, one end of the opening groove 24311 is close to the top edge of the friction plate 243, and the other end of the opening groove 24311 extends outward in a direction perpendicular to the extending direction of the bottle conveying channel 210. The connecting piece 2431 is fixed to the top surface of the mounting frame 241 through a fastener inserted into the opening groove 24311.

[0090] As Figure 6 shown, the position of the bottom surface of the guiding groove 2421 relative to the output surface of the output bottle cap 60 of the bottle cap conveying device 22 can be adjusted through the lifter 244, so that the bottle cap guiding plate 242 can adapt to the production requirements of bottle caps 60 with different heights.

[0091] As Figure 1 and Figure 6 shown, the friction plate 243 is fixed to the mounting frame 241 through the connecting piece 2431, so that the friction plate 243 has better mounting stability, and the effectiveness of the frictional contact between the friction plate 243 and the outer peripheral surface of the bottle cap 60 can be improved.

[0092] As Figure 6 shown, by adjusting the position of the fastener in the corresponding opening groove 24311, the distance between the plate surface of the friction plate 243 and the side surface of the bottle conveying channel 210 can be adjusted, so as to adapt to the production requirements of bottle caps 60 with different diameters.

[0093] As Figure 6 shown in the embodiment, an adjusting screw 2411 is installed in the middle of the mounting frame 241; the adjusting screw 2411 is used to adjust the mounting height of the mounting frame 241 relative to the top surface of the bottle conveying channel 210.

[0094] By turning the adjusting screw 2411, the distance between the top surface of the mounting bracket 241 and the top surface of the bottle conveying channel 210 can be adjusted, and the distance between the bottom edge of the adjustable friction plate 243 and the top surface of the bottle conveying channel 210 can be adjusted.

[0095] In a preferred embodiment, the midline of the bottle conveying channel 210 in the horizontal direction and the midline of the guiding groove 2421 in the horizontal direction are located in the same plane perpendicular to the conveyor belt 10.

[0096] In this way, the accuracy of the bottle cap 60 aligning with the mouth of the bottle body 61 can be improved, and the phenomenon of the bottle cap 60 being skewed can be reduced.

[0097] Furthermore, the limiting component 32 includes at least two limiting baffles 321;

[0098] The limiting baffles 321 extend along the running direction of the conveyor belt 10. Two of the limiting baffles 321 are horizontally opposite to each other and are arranged above the conveyor belt 10. The limiting baffles 321 are located between the electromagnetic induction heating plate 312 and the conveyor belt 10. The gap between the two limiting baffles 321 forms a limiting channel 3210 for restricting the movement of the medicine bottles.

[0099] Along the running direction of the conveyor belt 10, the central axis of the electromagnetic induction heating plate 312 and the central axis of the limiting channel 3210 are vertically aligned.

[0100] As Figure 2 shown, the two limiting baffles 321 can prevent the offset medicine bottles from entering the limiting channel 3210, avoiding the influence on the effect of sealing the bottle mouth due to partial heating of the aluminum film in the offset medicine bottles; through the guidance of the limiting channel 3210, the medicine bottles moving in the limiting channel 3210 can pass directly below the electromagnetic induction heating plate 22, so that the aluminum film in the medicine bottles in the limiting channel 3210 can be instantaneously heated by the electromagnetic induction heating plate 22 to completely seal the bottle mouth of the medicine bottles.

[0106] Pressing the adjustment button 3131 can synchronously adjust the lengths of the two downward-extending heating plate connecting rods 311.

[0107] As Figure 2 shown, by adjusting the position where the lower end of the first height adjustment frame 322 is clamped in the second fixed clamp, the distance between the bottom surface of the limit baffle 321 and the top surface of the conveyor belt 10 can be adjusted, and by pressing the adjustment button 3131, the length of the downward extension of the heating plate connecting rod 311 can be synchronously adjusted, so as to adjust the distance between the bottom surface of the electromagnetic induction heating plate 312 and the top surface of the conveyor belt 10, which can meet the production requirements for sealing medicine bottles of different heights.

[0108] Further, the limit component 32 further includes a first fixed clamp 324;

[0114] As Figure 2 and Figure 5As shown, when a medicine bottle stops and approaches the input port of the limit channel 3210 or the rear end face of the vertical rod 3232, the corresponding sensor is triggered and sends a signal to the controller 313. The controller 313 lights the corresponding alarm signal lamp 314 and emits an alarm sound to remind the operator to immediately remove the medicine bottle staying at the corresponding position, or controls the corresponding manipulator to remove the medicine bottle staying at the corresponding position.

Figure 3 The conveyor belt 10 in it is provided with a labeling station 102, and the labeling station 102 is located in front of the running direction of the sealing station 101. The labeling machine 41 is provided with a label output port 410, and the label output port 410 is located at the input end of the labeling channel 4100.

[0122] As Figure 3 and Figure 4 shown in the labeling device 4 of the present utility model, the spacing adjustment device 42 adopted by the labeling device 4 includes two turntables 421; the spacing between two medicine bottles output from two adjacent grooves 4211 can be adjusted by adjusting the rotation speeds of the two turntables 421.

[0123] If it is necessary to avoid the phenomenon that one label is pasted on the outer peripheral surfaces of two medicine bottles and avoid the resulting label waste and rework, as long as the rotation speeds of the two turntables 421 are adjusted so that the spacing between two medicine bottles output from two adjacent grooves 4211 is the same as the moving distance of any medicine bottle for labeling in the labeling channel 4100.

[0124] Specifically, the spacing adjustment device 42 includes a driver 420, a transmission rod 424, a sprocket transmission assembly 423, two rotating shafts 422 and two of the turntables 421;

[0125] The sprocket transmission assembly 423 includes an output gear 4231, a transmission gear 4232, a transmission chain 4233, two first driven gears 4234 and two second driven gears 4235;

[0126] The driver 420 is installed below the conveyor belt 10 near the turntable 421; the transmission rod 424 is mounted below the conveyor belt 10; the output end of the driver 420 and the transmission rod 424 respectively extend along the direction perpendicular to the running direction of the conveyor belt 10; both ends of the transmission rod 424 are exposed on both sides of the conveyor belt 10;

[0127] The output gear 4231 is sleeved on the output end of the driver 420, and the transmission gear 4232 is sleeved on the middle part of the transmission rod 424; the transmission chain 4233 is sleeved on the outer peripheral surface of the output gear 4231 and the outer peripheral surface of the transmission gear 4232, and the transmission chain 4233 drives the output gear 4231 and the transmission gear 4232 to rotate synchronously; two of the first driven gears 4234 are respectively sleeved on both ends of the transmission rod 424; two of the second driven gears 4235 are respectively sleeved on the lower ends of the two rotating shafts 422; the two first driven gears 4234 and the two second driven gears 4235 are engaged with each other in one-to-one correspondence; the turntable 421 is sleeved on the outer peripheral surface of the corresponding rotating shaft 422.

[0128] As Figure 3 and Figure 4 shown, through the cooperation of the output gear 4231, the transmission gear 4232 and the transmission chain 4233, the driver 420 drives the transmission rod 424 to rotate, and through the two first driven gears 4234 and the two second driven gears 4235 that are engaged with each other in one-to-one correspondence, drives the two rotating shafts 422 to rotate synchronously and in opposite directions, and further drives the two turntables to rotate synchronously in opposite directions.

[0129] As Figure 3 shown in the embodiment, the distance between the two rotating shafts 422 is adjustable.

[0130] By adjusting the distance between the two rotating shafts 422, the distance between the outer peripheral surfaces of the two turntables 421 can be adjusted, so that the medicine bottle labeling line can be applicable to the labeling production of medicine bottles with different outer diameters.

[0131] Preferably, the arc distance between two adjacent ones of the grooves 4211 is the same as the length of the labeling channel 4100 in the horizontal direction.

[0132] The linear velocity of the conveyor belt 10 can be set with reference to the length of the label to be pasted and the length of the labeling channel 4100 in the horizontal direction, so that the moving distance of the medicine bottle during labeling in the labeling channel 4100 is equal to the length of the labeling channel 4100 in the horizontal direction, and the arc distance between two adjacent ones of the grooves 4211 is set to be the same as the length of the labeling channel 4100 in the horizontal direction. In this way, the linear velocity of the rotation of the two turntables 421 and the linear velocity of the operation of the conveyor belt 10 can be kept the same during labeling production, which can not only improve the smoothness of the movement of the medicine bottle to be labeled on the conveying surface, but also enable the medicine bottle labeling line to have a high production efficiency.

[0133] In summary, as Figure 1-6In the embodiment of the utility model shown, the medicine bottle packaging line limits the left and right movement of the bottle cap 60 by the groove walls on both sides of the guide groove 2421 to prevent the bottle cap 60 from being offset, and corrects the horizontality of the top surface of the bottle cap 60 by the bottom surface of the groove wall at the rear end of the guide groove 2421 to reduce the proportion of medicine bottles with crooked bottle caps, and then blocks medicine bottles with crooked bottle caps or bottle caps that are not screwed into place by the height limiting cross bar 3231, which can prevent medicine bottles with crooked bottle caps or bottle caps that are not screwed into place from entering under the electromagnetic induction heating plate 312, thereby reducing the proportion of medicine bottles with incompletely sealed bottle mouths output by the medicine bottle packaging line, thereby improving the output quality of the medicine bottle packaging line.
