Description

Technical Field

[0001] This utility model relates to the field of medicine box detection technology, and more specifically, to a weighing and rejection mechanism for acetaminophen dihydrocodeine tablet medicine boxes. Background Technology

[0002] Acetaminophen dihydrocodeine tablets are indicated for a wide range of pain: traumatic pain, postoperative pain and pain from family planning surgery, moderate cancer pain, muscle pain such as back pain, back pain, myopathic pain, headache, toothache, dysmenorrhea, neuralgia, and persistent pain caused by strain, sprain, sinusitis, etc. Acetaminophen dihydrocodeine tablets need to be packaged in a medicine box after the production is completed.

[0003] Patent publication number CN219821957U discloses an empty box detection device for pharmaceutical packaging boxes: including a frame, a first sensor connected to a controller, a conveyor belt, a weighing component, and a rejection mechanism; the invention features a first sensor to detect when a medicine box reaches a suitable weighing position, causing the controller to stop the conveyor belt and simultaneously send a delayed opening message to the rejection mechanism; subsequently, the weighing component weighs the medicine box, and if the measured weight is the weight of an empty box, the weighing component will not output any feedback information, and then the rejection mechanism will be activated to reject the measured medicine box; when the measured weight matches the actual weight of the medicine box, the controller will start the conveyor belt to transport the medicine box to the next process, and simultaneously disconnect the delayed opening state of the rejection mechanism; therefore, this device replaces manual inspection for empty box detection and rejection, eliminating the need for significant labor costs and improving production efficiency.

[0004] However, in patent publication number CN219821957U, the controller extends the cylinder, the bellows suction cup picks up the medicine box, then the cylinder retracts, the motor starts, the lead screw rotates, causing the nut seat to move. When the nut seat moves to the position of the second sensor, the controller starts the conveyor belt and stops the air supply to the bellows suction cup, the medicine box falls into the medicine box box and is then reset. This results in low rejection efficiency to some extent. Therefore, we propose a acetaminophen dihydrocodeine tablet medicine box weighing rejection mechanism to solve the above-mentioned problems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] Please see Figure 1-4 A weighing and rejection mechanism for acetaminophen dihydrocodeine tablet boxes includes a first belt conveyor 1 and a second belt conveyor 2. A bracket 3 is installed at the end of the first belt conveyor 1 and the end of the second belt conveyor 2. A stepper motor 4 is installed on the top bottom wall of the bracket 3.

[0038] A rotating shaft 5, which is connected to the power output end of the stepper motor 4, is installed on the upper part of the bracket 3. A turntable 6 is installed on the outer wall of the rotating shaft 5. A notch 7 is provided on the edge of the turntable 6, and multiple notches 7 are provided in the radial position of the turntable 6.

[0039] A load cell 8 is installed on the edge of the top surface of the support 3. A carrier plate 9 is installed on the load cell 8. Guide tables 10 are installed on both sides of the carrier plate 9.

[0040] The end of the first belt conveyor 1 is equipped with a conveyor plate 11 with a horn-shaped structure, and the narrow end of the conveyor plate 11 extends to the port of the notch 7.

[0041] A double-acting cylinder 12 is mounted on the side of the load cell 8 away from the top edge of the bracket 3 via a fixed seat, and there are two double-acting cylinders 12.

[0042] A medicine box 13 is placed on the side of the support 3 away from the first belt conveyor 1;

[0043] The first belt conveyor 1 carries the medicine box body 14;

[0044] The top of the medicine box body 14 protrudes from the upper surface of the turntable 6, and the size of the medicine box body 14 is adapted to the notch 7;

[0045] It should be noted that, during use, the acetaminophen / dihydrocodeine tablet weighing and rejection mechanism uses a stepper motor 4, a weighing sensor 8, and a double-acting cylinder 12 connected to an external control device. The control device controls the stepper motor 4 to drive the rotating shaft 5 at a suitable angular velocity, ensuring that the notch 7 always aligns with the narrow end of the conveyor plate 11 when the turntable 6 rotates by the same angle. The tablet body 14, conveyed on the first belt conveyor 1, is transported to the inside of the notch 7 via the conveyor plate 11. Through the continuous rotation of the turntable 6, and in conjunction with the guide table 10, the tablet is transferred to the carrier plate 9. The weighing sensor 8 then weighs the tablet body. When an empty medicine box body 14 is detected, the control device controls the movable end of one of the double-acting cylinders 12 to extend, pushing the empty medicine box body 14 into the medicine box box 13 for rejection. The medicine box body 14 with the actual weight continues to be conveyed by the turntable 6 until it corresponds to the second belt conveyor 2. Then, the movable end of the other double-acting cylinder 12 extends, and the medicine box body 14 with the actual weight is pushed onto the second belt conveyor 2 and conveyed to the next process. Rejection and conveying can be carried out continuously, which improves work efficiency. The weighing sensor 8 can be of model JLBU-1.

[0046] like Figure 1 As shown, the conveyor belt of the first belt conveyor 1 is located above the turntable 6;

[0047] The conveyor belt of the second belt conveyor 2 is located below the top of the support 3;

[0048] It should be noted that this facilitates the normal delivery of the medicine box body 14.

[0049] like Figure 1 , Figure 2 As shown, the rotating shaft 5 passes through the top end of the bracket 3, and the top end of the bracket 3 is equipped with a bearing that is interference-fitted with the rotating shaft 5.

[0050] A coupling is installed between the bottom end of the rotating shaft 5 and the power output shaft of the stepper motor 4;

[0051] It should be noted that this reduces the resistance of the rotating shaft 5 during rotation and ensures the rotational accuracy of the rotating shaft 5, while also ensuring that the power transmitted by the stepper motor 4 can be properly transmitted to the rotating shaft 5.

[0052] like Figure 4 As shown, the top of the inclined surface on the guide table 10 is on the same horizontal plane as the upper surface of the carrier plate 9.

[0053] It should be noted that the medicine box body 14 can be transported to the carrier plate 9 via the inclined surface provided on the guide table 10, thereby realizing the weighing of the medicine box body 14.

[0054] like Figure 1As shown, a limiting boss is integrally formed on the edge of the upper surface of the conveyor plate 11;

[0055] It should be noted that the medicine box body 14 should be prevented from falling off when it slides on the conveyor plate 11.

[0056] like Figure 1 , Figure 4 As shown, the movable end of one of the double-acting cylinders 12 corresponds to the medicine box 13;

[0057] The movable end of another double-acting cylinder 12 corresponds to the second belt conveyor 2;

[0058] It should be noted that, through the different functions of the double-acting cylinders 12, the medicine box body 14 can be removed or transferred to the next process.

[0059] In use: A stepper motor 4, a weighing sensor 8, and a double-acting cylinder 12 are connected to an external control device. The control device controls the stepper motor 4 to drive the rotating shaft 5 to rotate at a suitable angular velocity, so that when the turntable 6 rotates by the same angle, the notch 7 always corresponds to the narrow end of the conveyor plate 11. The medicine box body 14 conveyed on the first belt conveyor 1 is conveyed to the inside of the notch 7 through the conveyor plate 11. Through the continuous rotation of the turntable 6, the medicine box is conveyed to the carrier plate 9 in conjunction with the guide table 10. The weighing sensor 8 weighs the medicine box body. When an empty medicine box body 14 is detected, the control device controls the movable end of one of the double-acting cylinders 12 to extend, pushing the empty medicine box body 14 into the medicine box box 13 for rejection. The medicine box body 14 with the actual weight continues to be conveyed by the turntable 6 until it corresponds to the second belt conveyor 2. Then, through the extension of the movable end of the other double-acting cylinder 12, the medicine box body 14 with the actual weight is pushed onto the second belt conveyor 2 and conveyed to the next process.

[0060] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
