[0019] Embodiment: A rejection and collection device includes a drug packaging conveyor line, a drug weighing and detection device 4, a drug rejection device, a defective product collection box 5 and a control system 7, wherein the drug weighing and detection device 4 is arranged on the drug packaging conveyor line, and the medicine box 9 containing the medicine can be conveyed to the drug weighing and detection device 4 to weigh the medicine box 9, and the drug weighing and detection device 4 can transmit the weighing data of the medicine box 9 to the control system 7, the drug rejection device is installed on one side of the end of the drug packaging conveyor line, and the defective product collection box 5 is installed on the other side of the end of the drug packaging conveyor line, and the defective product collection box 5 is provided with a drug inlet 51 on the side wall facing the drug packaging conveyor line, and a drug removal port is provided on the lower side wall of the defective product collection box 5, and a door 52 that can be opened or closed is provided on the drug removal port, and the control system 7 can control the drug rejection device to send the unqualified weighing medicine boxes 9 into the defective product collection box 5 through the drug inlet 51 for collection.
[0020] After the inner packaging of the medicine is boxed at the front section of the medicine packaging conveyor line, it flows to the rear section along the medicine packaging conveyor line. After the medicine box 9 arrives at the medicine weighing and detection device 4, the medicine weighing and detection device 4 weighs the medicine box 9. When its weight is within the specified weight range, the control system 7 determines that it is a qualified product. The medicine box 9 finally flows out from the rear end of the medicine packaging conveyor line for boxing. If its weight is outside the specified weight range, such as less than the specified weight or greater than the specified weight, it is judged to be unqualified. After the medicine box 9 reaches the rejection position, the medicine rejection device sends it to the medicine inlet 51 of the defective product collection box 5. The unqualified medicine box 9 is collected and stored in the defective product collection box 5. When the amount of unqualified products in the defective product collection box 5 reaches a certain amount, the worker opens the door 52 on the medicine removal port of the defective product collection box 5, takes out the medicine box 9, and reworks it. This device realizes automatic detection of over-packing and under-packing of boxed medicines, and automatically rejects unqualified products without manual operation and without misjudgment.
[0021] The bottom 53 of the defective product collection box is an inclined surface, forming an acute angle with the side wall where the medicine dispensing port is located. The bottom 53 of the defective product collection box is designed as an inclined surface, so that after the medicine slides to the bottom of the defective product collection box 5, it will automatically move towards the dispensing port, facilitating quick dispensing.
[0022] The door is installed on the lower side wall of the defective product collection box 5 and can be rotated around a horizontal rotation axis. A knob handle 54 is installed on the door to rotate to a set angle. The handle at one end of the knob handle 54 is located on the outer side wall of the door facing away from the defective product collection box 5. The locking piece 541 at the other end of the knob handle 54 can be stopped on the inner side wall of the lower end of the defective product collection box 5 or detached from the inner side wall of the lower end of the defective product collection box 5 as the knob handle 54 rotates. The two sides of the door are also fixed on connecting plates 55 respectively. The connecting plates 55 can be relatively rotated and flat on the outer sides of the two side walls of the defective product collection box 5. The connecting plates 55 are provided with an arc groove 551 which is concentric with the horizontal rotation axis of the door. The outer sides of the two side walls of the defective product collection box 5 are provided with limiting protrusions 56. The limiting protrusions 56 can be relatively slidably inserted into the arc grooves 551 of the connecting plates 55. When removing the defective medicine box 9, the handle of the rotating knob handle 54 drives the locking piece 541 to rotate and disengage from the side wall of the defective product collection box 5 above the material removal port, so that the door can be flipped open. After opening to a certain angle, the limiting protrusion 56 is limited by the arc groove 551, and the door cannot continue to flip, so that the door forms a horizontally extended state, which facilitates the medicine box 9 to slide out along the door.
[0023] The medicine inlet 51 of the defective product collection box 5 is also provided with a counter, which can count the medicine boxes 9 entering the defective product collection box 5. The counter is electrically connected to the control system 7 and is also provided with an alarm 8. The control system 7 can control the alarm to sound an alarm based on the count data of the counter. The counter automatically counts the medicine boxes 9 entering the defective product collection box 5 to prevent the defective product collection box 5 from being filled with medicine boxes 9 and not being cleared in time, resulting in the inability of defective medicine boxes 9 to enter, thereby preventing the failure of rejecting defective medicine boxes 9.
[0024] The sidewall of the defective product collection box 5, directly opposite the medicine inlet 51, is a guide slope 57. The distance between the upper end of the guide slope 57 and the sidewall where the medicine inlet 51 is located is greater than the distance between the lower end of the guide slope 57 and the sidewall where the medicine inlet 51 is located. The slope 57 transitions with the upper end surface of the defective product collection box 5 and the sidewall where the guide slope 57 is located via an arc surface. After the defective medicine box 9 enters the defective product collection box 5 from the medicine inlet 51, it collides with the guide slope 57 due to inertia and falls along the guide slope 57 into the interior of the defective product collection box 5, preventing the medicine box 9 from hitting the sharp corners of the defective product collection box 5 and causing damage.
[0025] A mounting bracket for a defective product collection box 5 is also provided, and the mounting bracket for the defective product collection box 5 includes a fixed bracket 11, a front and rear adjustment bracket 12, a height adjustment bracket 13, a front and rear positioning locking device, and a height positioning locking device. The fixed bracket 11 is fixedly installed on the side wall of the frame of the pharmaceutical packaging conveyor line, and the front and rear adjustment brackets can be horizontally slid along the width direction of the pharmaceutical packaging conveyor line and installed on the fixed bracket 11. The front and rear positioning locking devices can fix and lock the front and rear adjustment brackets adjusted to any position with the fixed bracket 11. The height adjustment bracket can be installed on the front and rear adjustment bracket 12 for sliding up and down in the vertical direction. The height positioning locking device can fix and lock the height adjustment bracket 13 adjusted to any height position with the front and rear adjustment bracket 12. The defective product collection box 5 is fixedly installed on the height adjustment bracket 13.
[0026] The defective product collection box 5 is installed on the side wall of the frame of the medicine packaging conveyor line through the defective product collection box 5 installation bracket to collect defective medicine boxes 9. During installation, the front and rear position and height position of the defective product collection box 5 are adjusted through the front and rear adjustment frame 12 and the height adjustment frame 13, which facilitates the control of the medicine box 9 to accurately pass through the medicine inlet 51 and fall into the defective product collection box 5.
[0027] The drug rejection device is a high-pressure air blowing nozzle 6, which is fixedly installed on the other side of the end of the drug packaging conveyor line. The high-pressure air blowing nozzle 6 is arranged directly opposite the drug inlet 51 of the defective product collection box 5. The control system 7 can control the high-pressure air blowing nozzle 6 to blow out high-pressure air to blow the medicine box 9 at the end of the drug packaging conveyor line into the drug inlet 51 of the defective product collection box 5. In addition to using the high-pressure air blowing nozzle 6 to blow the medicine box 9 into the drug inlet 51 of the defective product collection box 5, a push plate can also be used to push the medicine box 9 into the drug inlet 51 of the defective product collection box 5. This is an equivalent replacement structure that can be easily thought of by counting personnel in this field based on this application and falls within the scope of protection of this application.
[0028] The side wall of the defective product collection box 5 is provided with a plurality of ventilation holes 58. The ventilation holes are used for the outflow of high-pressure gas to avoid the formation of vortex at the feed port of the defective product collection box 5, which causes the medicine box 9 to be unable to enter the defective product collection box 5 smoothly.
[0029] A protective cover 14 is also fixedly mounted at the end of the medicine packaging conveyor line. The protective cover 14 extends across the end of the medicine packaging conveyor line. One end of the protective cover 14 is connected to the upper end of the medicine inlet 51 of the defective product collection box 5 via a guide slope 57. The protective cover 14 prevents the medicine boxes 9 from flying out of the defective product collection box 5.
[0030] The pharmaceutical packaging conveyor line comprises a main conveyor line 1, a weighing conveyor line 2, and a receiving conveyor line 3. These three lines are connected sequentially along the conveying direction of the medicine boxes 9. A control system 7 controls the start and stop of each of these lines, respectively. A pharmaceutical weighing detection device 4 is a weighing sensor located on the weighing conveyor line 2. The pharmaceutical rejection device and defective product collection box 5 are located on either side of the width of the receiving conveyor line 3. The three-stage conveyor line controls start and stop operations, enabling continuous forward conveyance and discharge of the medicine boxes 9 on the main conveyor line 1, while allowing intermittent forward conveyance on the weighing conveyor line 2 and the receiving conveyor line 3, allowing for convenient stopping for precise weighing and accurate rejection of defective products.
