The working principle of the medicine bottle labeling machine is briefly described below:
(1) The working principle of the whole machine is as follows:
A medicine bottle feeding apparatus (e.g., a vibrating plate) is provided at one side of the main conveyor 1, and the medicine bottle feeding apparatus is located in front of the bottle dividing apparatus 2.
In operation, the medicine bottle supply device is used for continuously supplying medicine bottles to the main conveyor belt 1, and the medicine bottles are closely arranged in a row on the main conveyor belt 1 from front to back in sequence; the medicine bottles are driven by the main conveyor belt 1 to move from front to back and sequentially pass through the bottle separating device 2, the medicine bottle dumping and removing device 6, the righting chain device 3 and the labeling device 5. When the medicine bottles pass through the bottle separating device 2, the two bottle separating motors respectively drive the corresponding rotating shafts 22 to rotate, drive the two bottle separating wheels 21 to rotate relatively, and enable the conveying speed of the two bottle separating wheels 21 to be smaller than the bottle conveying speed of the main conveying belt 1; the medicine bottles enter between the two bottle separating wheels 21 under the driving of the main conveying belt 1, the two bottle separating wheels 21 clamp the passing medicine bottles and drive the medicine bottles to move from front to back, at the moment, the moving speed of the medicine bottles is controlled by the two bottle separating wheels 21, and the medicine bottles are uniformly separated from the medicine bottles leaving the bottle separating device 2 according to a certain interval by utilizing the speed difference of the medicine bottles. When the medicine bottles pass through the medicine bottle dumping and removing device 6, the medicine bottles in a dumping state on the main conveying belt 1 are removed by the medicine bottle dumping and removing device 6, and the medicine bottles in a standing state continuously move from front to back under the drive of the main conveying belt 1. When the medicine bottle passes through the righting chain device 3, the righting chain device 3 righting clamps and positions the passing medicine bottle and conveys the medicine bottle to the lower part of the top pressure belt device 4; the bottles are clamped together by the top pressure belt device 4 and the main conveyor belt 1 and moved from front to back into the labeling device 5, so that the bottles can be ensured to have a certain posture and accurate positioning in the labeling process. When the medicine bottle passes through the labeling device 5, the label supply device 51 conveys the label to the front of the former 52 with the front of the label (i.e., the side on which the information is printed) being located on the side near the former 52 and the back of the label (i.e., the side having the adhesive) being located on the side far from the former 52; The medicine bottles sequentially pass through the label supply device 51, the former 52 and the label pushing device 53 under the common drive of the top pressure belt device 4and the main conveyor belt 1, the labels in front of the former 52 are attached to one side surface of the passing medicine bottles, and when passing between the two forming plates 521, the two side parts of the medicine bottles are respectively bent forwards into a U shape (the cross section of the labels is U-shaped) by the two forming plates 521, and the labels are torn off along with the movement of the medicine bottles (the toothed blocks between the foremost labels and the next foremost labels are broken); then the medicine bottle and the label on the medicine bottle enter between two labeling rollers 531, the two bending parts of the label are smoothed and pressed by the two labeling rollers 531, and the medicine bottle is applied to the specified positions of the two side surfaces adjacent to the labeling surface of the medicine bottle without bubbles or wrinkles, so that the automatic labeling of the medicine bottle is completed. The gap width between the two forming plates 521 and the gap width between the two labeling rollers 531 are equal to the required labeled medicine bottle width. When the label is labeled, when the width of the label sent by the label supply device 51 is the same as the width of the labeling surface of the medicine bottle, the sent label can be just positioned between the two forming plates 521, and the label can be labeled on the labeling surface of the medicine bottle; when the width of the label fed from the label feeding device 51 is larger than the width of a single side surface of the medicine bottle, the fed label can be made to cross the gap between the two forming plates 521, the two forming plates 521 are used for bending the two side parts of the label during labeling, and the two bending parts of the label are applied to the prescribed positions of the two side surfaces adjacent to the labeling surface by the two labeling rollers 531.
(2) Principle of operation of the vial dumping and rejecting device 6:
The upper photo eye 66 and the lower photo eye 67 are respectively connected with corresponding input ends of the control circuit, and the switch valve 652 is connected with corresponding output ends of the control circuit.
In operation, the medicine bottles coming out of the bottle separating device 2 are driven by the main conveyor belt 1 to move from front to back and pass through the space between the supporting frame 62 and the collecting container 63; the upper photo eye 66 and the lower photo eye 67 are used for detecting whether the medicine bottles passing through the main conveyor belt 1 between the supporting frame 62 and the collecting container 63 are in a standing state or a toppling state, and sending signals to the control circuit for processing. When a vial passing between the support frame 62 and the collection container 63 is detected by both the upper photo eye 66 and the lower photo eye 67 (i.e., the vial is in a standing state), the control circuit keeps the on-off valve 652 closed so that the gas supply device 65 cannot supply gas to the gas nozzle 64 through the gas pipe 651, and the main conveyor 1 continues to convey the vial into the labeling device 5. When a vial passing between the support frame 62 and the collection container 63 is detected by the lower photo eye 67 but not by the upper photo eye 66 (i.e., the vial is in a toppled state), the control circuit opens the switch valve 652, and the gas supply device 65 supplies gas to the cavity of the gas nozzle 64 through the gas supply pipe 651, and then jets gas toward the vial through the gas jet port 641 of the gas nozzle 64, blowing the vial into the collection container 63.
When the support frame 62 needs to be adjusted in the left-right direction, the positions of the support frame 62, the air nozzle 64, the upper photoelectric eye 66 and the lower photoelectric eye 67 in the left-right direction can be adjusted by enabling each adjusting screw 622 to relatively move in the corresponding first strip-shaped through hole 621; when the supporting frame 62 needs to be adjusted in the height direction, the positions of the supporting frame 62, the air nozzle 64, the upper photoelectric eye 66 and the lower photoelectric eye 67 in the height direction can be adjusted by adjusting the positions of the first nuts 623 on the corresponding adjusting screws 622; after the position of the support frame 62 is determined, each first nut 623 is tightened to lock the support frame 62 to each adjustment screw 622.
When the spacing between the upper photoelectric eye 66, the lower photoelectric eye 67 and the air nozzle 64 needs to be adjusted, the two second nuts 626 are unscrewed firstly, and then the positions of the upper photoelectric eye 66 and the lower photoelectric eye 67 in the front-rear direction are adjusted by relatively moving the two positioning bolts 625 in the corresponding second strip-shaped through holes 624, so that the spacing between the lower photoelectric eye 67 and the air nozzle 64 is changed, and the air nozzle 64 can smoothly blow the medicine bottle into the collecting container 63 when the passing medicine bottle is detected to be in a toppling state; after the positions of the upper photo eye 66 and the lower photo eye 67 are determined, two second nuts 626 are tightened to lock the two positioning bolts 625 to the support frame 62.
(3) The principle of operation of the label supply means 51:
In operation, the label tape unwind roller 512 is used to store a roll of label tape 510 and release the label tape 510; the traction motor drives the driving traction wheel 5161 to rotate in a stepping manner, so that the first driven traction wheel 5162 and the second driven traction wheel 5163 relatively rotate, and the label tape 510 is driven to move in a stepping manner and sequentially passes through the tensioning wheel 5172, the code spraying machine 513, the label stripping block 514 and the base band winding roller 515. When the label tape 510 passes through the ink jet machine 513, the ink jet machine 513 ink-prints information such as the name of the medicine, the manufacturer, the date of production, etc. on the front surface of the label. When the label tape 510 passes through the label peeling block 514, the label tape 510 bypasses the peeling part 5141 of the label peeling block 514, and the tape 510 and the label are separated under the action of the peeling part 5141 because the peeling part 5141 is wedge-shaped, the separated label moves to the front of the two forming plates 521, sticks to the passing medicine bottle and is torn off along with the advancing of the medicine bottle (the toothed block between the forefront label and the next forefront label breaks), and the separated tape continuously moves under the common drive of the driving traction wheel 5161 and the second driven traction wheel 5163 and is wound by the tape winding roller 515.
When the label tape 510 is in a loose state, the outer end of the swing arm 5171 and the tension pulley 5172 move toward the label tape 510 under the self-tension of the elastic tape 5173, so that the label tape 510 is automatically restored to a tensioned state, and the ink jet printer 513 can be ensured to accurately jet-print information such as the name, manufacturer, date of manufacture, etc. of the medicine on the front surface of the label.
In addition, it should be noted that, in the specific embodiments described in the present specification, names of various parts and the like may be different, and all equivalent or simple changes of the structures, features and principles described in the conception of the present invention are included in the protection scope of the present invention.
