As shown in fig. 1 and referring to fig. 2, an embodiment of the present invention provides a conveying mechanism of a vertical medicine box packaging apparatus, which includes a pill loading station 1, a capping station 2, and a hot melting station 3, which are sequentially arranged. A first conveying mechanism is connected between the pill filling station 1 and the sealing station 2, and a second conveying mechanism is connected between the sealing station 2 and the hot melting station 3. After the pill filling is carried out at the pill filling station 1, the vertical medicine box is conveyed from the pill filling station 1 to the sealing station 2 for sealing through the first conveying mechanism. The vertical medicine box is conveyed to the hot melting station 3 through the second conveying mechanism after being capped, and labeling operation is carried out on the side wall of the vertical medicine box.
The first conveyor mechanism includes a first main conveyor belt 11 and a buffer conveyor platform. A first main conveyor belt 11 is connected between the pelleting station 1 and the capping station 2. The buffer conveyor is disposed at one side of the first main conveyor 11, and an inlet 121 and an outlet 122 connected to the first main conveyor 11 are formed at both ends of the first main conveyor 11, respectively.
The buffer conveying platform comprises at least two conveying belts 15 which are alternately arranged in a coplanar and parallel mode in the width direction, and the conveying directions of the two adjacent conveying belts 15 are opposite to each other. The buffer conveying platform further comprises a surrounding rail above the conveying belts 15, wherein the surrounding rail forms an interface part communicated with the inlet 121 and the outlet 122, an arc-shaped channel 17 in arc-shaped transitional connection between the end parts of two adjacent conveying belts 15, and a linear channel 16 parallel to the conveying belts 15 and connected between the interface part and the arc-shaped channel 17 or between the two arc-shaped channels 17. The rail is wholly of a serpentine structure, and the vertical medicine boxes are conveyed forwards on the conveyor belt 15 along the linear channel 16 and are moved to the adjacent conveyor belt 15 by means of the conveyor belt 15 and the rail at the arc-shaped rail.
The outer ring of the rail forms a discharge opening 18 communicating with the arcuate channel 17 and adjacent the inlet opening 121. The upper side of the discharge opening 18 forms a guide edge 19 for stopping the vertical cartridge to facilitate the removal of the poured vertical cartridge from the discharge opening 18.
In the embodiment of the present invention, the vertical medicine cartridge is normally introduced from the introduction port 121 and is transported out from the discharge port 122 by the conveyor belt 15 and the rail. When the vertical medicine box is toppled over, the toppled vertical medicine box is exposed from the discharge opening 18 under the action of the conveying belt 15 and falls off from the conveying belt 15, so that the problem that the toppled vertical medicine box is easy to block the conveying channel at the arc-shaped channel is solved, and the aim of improving the production operation efficiency is fulfilled.
Further, a guide 19 for preventing the vertical cartridge from being toppled is formed on the upper side of the discharge opening 18, and the non-toppled vertical cartridge can be transported rearward by the guide 19, preventing the non-toppled vertical cartridge from being exposed from the discharge opening 18.
In some embodiments of the present invention, as shown in fig. 1, a box pushing mechanism 13 is disposed at the inlet 121, and the box pushing mechanism 13 includes a first electric push rod fixed on a side wall of a mounting frame of the first main conveyor 11 through a mounting plate, and a box pushing plate disposed at an output end of the first electric push rod, the output end of the first electric push rod facing horizontally toward the inlet 121. The vertical cartridges are pushed from the first main conveyor 11 into the buffer deck 12 by the cartridge pushing mechanism 13. The box taking mechanism 14 is arranged at the outlet 122, the box taking mechanism 14 is of a sucker type manipulator structure, and the vertical medicine box is lifted to the first main conveying belt 11 from the buffer platform 12 through the box taking mechanism 14.
In some embodiments of the present invention, as shown in fig. 1, the discharge opening 18 is opposite to the linear passage 16 near the introduction port 121, and the opening width of the discharge opening 18 is greater than the width of the linear passage 16. Further, a flexible tongue piece 4 is connected to the side of the discharge opening 18 away from the inlet 121, and the tongue piece 4 and the edge of the discharge opening 18 define a discharge window smaller than the width of the linear passage 16. The tongue 4 is for example a cardboard or foil.
In this example of the invention, a portion of the vertical cartridge may tilt during delivery, resting against the side walls of the arcuate channel 17. The inclined cartridge does not cause blockage of the delivery channel but is also exposed from the discharge opening 18. Therefore, the flexible tongue piece 4 is connected to the side of the discharge opening 18 away from the inlet 121. When the poured vertical medicine box is abutted against the tongue piece 4, the tongue piece 4 can be greatly deformed, and the tongue piece 4 is removed at the moment, so that the poured vertical medicine box is exposed. When the inclined vertical medicine box is abutted on the tongue piece 4, the deformation of the tongue piece 4 is small, the tongue piece 4 does not need to be moved at the moment, and the width of the discharge window is smaller than that of the vertical medicine box, so that the inclined vertical medicine box cannot be exposed through the discharge window and can be continuously conveyed forwards. The tongue 4 is provided to prevent the inclined vertical medicine cartridge from being exposed from the discharge opening 18 and falling from the conveyor belt 15, while allowing the inclined vertical medicine cartridge to be exposed from the discharge opening 18 and falling from the conveyor belt 15.
In some embodiments of the present invention, as shown in fig. 1 and 2, the conveying mechanism further includes a telescopic driving mechanism connected to the tongue 4, the telescopic driving mechanism configured to drive the tongue 4 to expand and contract within the discharge opening 18, and a strain sensor 53 configured to detect a deformation amount of the tongue 4 to control expansion and contraction of the tongue 4 according to the deformation amount.
In this example of the present invention, the magnitude of the deformation of the tongue piece 4 is sensed by the strain sensor 53, and a signal is transmitted to the telescopic driving mechanism. The telescopic driving mechanism drives the tongue piece 4 to stretch and retract in the discharge opening 18, so that the toppled vertical medicine box is exposed from the discharge opening 18 and the inclined vertical medicine box is shielded. The deformation amount of the tongue piece 4 is automatically detected, the expansion and contraction of the tongue piece 4 is automatically controlled, and the exposure of the pouring medicine box and the shielding of the inclined medicine box are controlled more automatically, so that time and labor are saved.
In some embodiments of the present invention, as shown in fig. 1, the telescopic driving mechanism is a cylinder 51, and the cylinder 51 is fixedly connected to the upper side of the discharge opening 18 by a fixing plate 52, and the fixing plate 52 is disposed on the side wall of the arc-shaped passage 17. The output end of the cylinder 51 is fixedly connected to the side wall of the tongue 4, the output end of the cylinder 51 being arranged horizontally and facing the discharge opening 18. The cylinder 51 is simple in structure and low in cost. Of course, the telescopic driving mechanism can also be a hydraulic cylinder or a linear motor.
In some embodiments of the invention, as shown in fig. 1, the second conveyor mechanism includes a second main conveyor belt 21 and a sorting mechanism, the second main conveyor belt 21 being configured to convey vertical cartridges between the capping station 2 and the hot melt station 3. The sorting mechanism is located at the end of the second main conveyor belt 21 near the capping station 2. The sorting mechanism includes reject bins 22 and push-out mechanisms that are relatively distributed on both sides of the second main conveyor 21. The top of the reject bin 22 is open and below the belt surface of the second main conveyor belt 21. The pushing mechanism includes a detection probe 23 and a pneumatic push rod 24 arranged in this order in the conveying direction of the second main conveyor belt 21. The detection probe 23 is configured to detect pill level in the vertical cartridge and the pneumatic push rod 24 is configured to push the vertical cartridge on the second main conveyor belt 21 into the reject bin 22.
In this example of the present invention, the detecting probe 23 can determine the pill height in the vertical type medicine box, and determine the vertical type medicine box with the pill height lower than the set height as not reaching the standard, and transmit the signal to the pneumatic push rod 24, and the pneumatic push rod 24 pushes the vertical type medicine box not reaching the standard into the defective bin 22, so as to ensure the quality of the finished product. In this embodiment, the whole course adopts automated inspection, letter sorting, and is more intelligent, and production efficiency is higher moreover.
In some embodiments of the present invention, the detection probe 23 is an ultrasonic sensor that determines whether the pill level in the cartridge meets a standard based on the received reflected signal. The transmitting end of the ultrasonic sensor is aligned with the set height of the pill on the medicine box, when the height of the pill in the medicine box is lower than the set height, the reflected signal received by the ultrasonic sensor is relatively strong, and when the height of the pill in the medicine box is not lower than the set height, the reflected signal received by the ultrasonic sensor is relatively weak.
In some embodiments of the invention, as shown in fig. 1, the second main conveyor 21 includes a capping station back section 211, a hot melt station front section 212, and an offset rail 213. The rear section 211 of the capping station is of a conveyor belt structure and extends rearwardly to be exposed to facilitate rearward transport of the vertical medication box. The forward section 212 of the hot melt station is a conveyor belt structure and extends from the forward section to be exposed. The front section 212 of the hot melting station is staggered with the rear section 211 of the capping station left and right, so as to receive and convey the vertical medicine boxes sent out from the rear section 211 of the capping station.
The dislocated rails 213 form a front section channel disposed in parallel on the back section 211 of the capping station and a back section channel disposed in parallel on the front section 212 of the hot melt station. The front section channels are arranged in front of the rear section channels at intervals, and inclined channels are connected between the rear ends of the front section channels and the front sections of the rear section channels in an arc transition mode.
In this embodiment of the present invention, in order to reduce the occupied space of the apparatus, the conveyor belt at the junction of the capping station 2 and the hot melting station 3 is arranged in a side-by-side staggered manner, and by arranging the staggered rails 213, the vertical medicine box is conveyed from the capping station 2 to the hot melting station 3 along the staggered rails 213, so that the structure is relatively simple.

As shown in fig. 3, an embodiment of the present invention provides a control method for a conveying mechanism in some embodiments described above, including:
obtaining the deformation amplitude of the tongue piece 4;
in response to the magnitude of deformation of the tongue 4 not being lower than the first magnitude threshold, the telescopic driving mechanism is controlled so that the tongue 4 is pulled out of the discharge opening 18 by a set distance.
In this embodiment of the invention, by setting the first amplitude threshold, the first amplitude threshold is the lowest deformation amount when the toppled vertical cartridge abuts on the tongue 4. When the deformation amount of the tongue piece 4 is not lower than the first amplitude threshold value, the vertical medicine box is overturned, and the telescopic driving mechanism pulls the control tongue piece 4 out of the discharge opening 18 so that the overturned vertical medicine box is exposed from the discharge opening 18. Whether can be accurate detect through first range threshold value has the vertical medicine box of empting to effectually prevent that the conveying channel from blockking up.
In some embodiments of the invention, the control method further comprises, after controlling the telescopic drive mechanism to pull the tongue 4 out of the discharge opening 18 by a set distance, further comprising:

in response to the magnitude of deformation of the tongue 4 being not lower than the second magnitude threshold before the tongue 4 reaches the home position, the telescopic driving mechanism is controlled so that the tongue 4 is pulled out of the discharge opening 18.
In this example of the invention, the tab 4 is controlled to return to the starting position after the tab 4 is pulled out for a first set time for detecting again whether there is a pouring vertical cartridge. The first set time is set to fully expose the poured cartridge from the discharge opening 18.
During the return of the tongue 4 to the starting position, if the tongue 4 is deformed again, this is because there is a vertical cartridge that is continuously tipped. When the deformation amount of the tongue piece 4 is not lower than the second amplitude threshold, the second amplitude threshold is the deformation amount of the tongue piece 4, which is generated when the tongue piece 4 is abutted against another toppled vertical medicine box in the process of returning to the initial position. The telescopic driving mechanism again controls the tongue 4 to be pulled out of the discharge opening 18, and controls the tongue 4 to return to the initial position after the first set time is pulled out, and the telescopic driving mechanism is cycled until the tongue 4 returns to the initial position. The second amplitude threshold is set so that the tongue 4 can also detect a toppled vertical cartridge before the start position is reached and expose it from the discharge opening 18, so that a full, accurate prevention of a toppled vertical cartridge from causing a blockage of the conveyor belt 15 is achieved.

and controlling the first conveying mechanism to stop in response to the pushing-out times of the pneumatic push rod 24 in the second set time being not less than the first set threshold.
In this example of the invention, a vertical cartridge having a pill height not higher than the set level is pushed into the reject bin 22 and counted once, and when the number of pushes of the air push rod 24 in the second set time is not less than the first set threshold, the first conveying mechanism is controlled to stop. When detecting the defective products, when the number of times that the defective products appear in a certain time is too large, the conveying mechanism is likely to fail, and the machine halt checking can be carried out, so that the quality of the products is improved, the yield is controlled, and the production efficiency is improved.
In some embodiments of the invention, the control method further comprises:
controlling the first conveying mechanism to decelerate in response to the number of times of pushing out the pneumatic push rod 24 being not less than the second set threshold value and the conveying speed of the first conveying mechanism being not lower than the speed threshold value within the second set time;
judging whether the first conveying mechanism decelerates within the second set time,
if so, taking the deceleration moment of the first conveying mechanism as the starting moment of the second set time, and re-timing;
wherein the first set threshold is greater than the second set threshold.
In this embodiment of the present invention, when the number of pushing-out times of the air push rod 24 is not less than the second set threshold value but less than the first set threshold value and the conveying speed of the first conveying mechanism is not lower than the speed threshold value in the second set time, the defective rate can be reduced by reducing the conveying speed of the conveying belt of the first conveying mechanism, and the stop check is not required, thereby improving the production efficiency.
Further, whether the first conveying mechanism is decelerated is judged, if yes, the deceleration time of the first conveying mechanism is taken as the starting time of the second setting time, the pushing times of the pneumatic push rod 24 and the conveying speed of the first conveying mechanism in the second setting time are detected again, and smooth production is guaranteed.
