Description

Technical Field

[0001] The utility model belongs to the technical field of packaging devices, and particularly relates to a conveying and detecting device for effervescent tablet packaging tubes. Background Art

[0002] An effervescent tablet packaging tube is a special container for encapsulating effervescent tablets, usually in a tubular structure. To ensure the efficiency and quality of subsequent labeling, palletizing, and packing operations, the effervescent tablet packaging tubes usually need to be in the same direction and maintain a stable arrangement posture during transportation.

[0003] Chinese Patent CN116891031A discloses a device and method for neatly arranging and conveying effervescent tablet packaging tubes, including: a feeding unit, which includes: a base, a material frame arranged on the base, and a plate conveyor obliquely arranged on one side of the material frame; a large and small head distinguishing unit, which includes: a support seat, a circular material table arranged on the support seat, and a turntable arranged inside the circular material table. The upper surface of the turntable is a conical surface. A driving motor is installed in the support seat, and the output end of the driving motor is fixedly connected with an output rotating shaft. A screening gap is formed between the circular material table and the turntable. This patent uses the screening gap between the circular material table and the turntable to achieve the unification of the direction of the packaging tubes. However, the device still has the following defects in actual application: First, the packaging tubes are prone to collide with equipment components such as the turntable and the guide rail during the rotation of the turntable, resulting in the misalignment of the tube cap and the tube body or local deformation, affecting the subsequent sealing performance; Second, the conveying path is too long, and the packaging tubes will continuously rub against the conveyor belt during movement, easily causing scratches on the surface of the tube cap or deformation of the edge, reducing the sealing performance of the packaging tube. Effervescent tablets will rapidly generate carbon dioxide gas when encountering water. If the tube cap is not sealed properly, moisture or humidity will seep into the packaging tube, causing the effervescent tablets to fail, agglomerate, or deteriorate in advance, affecting the drug efficacy and even posing a safety risk. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a conveying and detecting device for effervescent tablet packaging tubes, which can timely detect the misalignment of the tube cap caused by collision and the surface damage caused by long-distance transportation, and avoid defective packaging tubes from entering the subsequent processes.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An effervescent tablet packaging tube conveying and detecting device, comprising a transport chain, a driving chain is cooperatively arranged on the transport chain, a driving shaft is arranged at one end of the driving chain, a tensioning shaft is arranged at the other end of the driving chain, a controller is arranged outside the transport chain, a photoelectric sensor group is arranged on the side of the controller close to the transport chain, a removal unit one and a removal unit two are arranged on the top of the controller, electric push rods are arranged on both the removal unit one and the removal unit two, a vacuum adsorber is arranged on the electric push rod, a servo motor is arranged at one end of the driving shaft, and the controller is electrically connected to the photoelectric sensor group, the removal unit one, the removal unit two, the vacuum adsorber and the servo motor respectively.

[0007] Further, an electric telescopic rod is arranged at the bottom of the vacuum adsorber, and a flexible air suction pipe is arranged inside the electric telescopic rod.

[0008] Further, a vacuum gripper is arranged at the end of the electric telescopic rod away from the vacuum adsorber, and several groups of suction nozzles are arranged on the vacuum gripper.

[0009] Further, one end of the flexible air suction pipe is communicated with the vacuum adsorber, and the other end of the flexible air suction pipe is communicated with the vacuum gripper.

[0010] Further, the photoelectric sensor group includes a photoelectric sensor one, a photoelectric sensor two and a photoelectric sensor three, and the photoelectric sensor one, the photoelectric sensor two and the photoelectric sensor three are uniformly arranged on the controller along the movement direction of the driving chain.

[0011] Further, the removal unit one and the removal unit two are respectively arranged on the top of the controller in cooperation with the photoelectric sensor two and the photoelectric sensor three.

[0012] Further, a touch screen and an alarm are arranged on the controller, and both the touch screen and the alarm are electrically connected to the controller.

[0013] Further, a support shaft is arranged between the tensioning shaft and the driving shaft.

[0014] Further, a recycling box is arranged on the outside of the transport chain away from the controller.

[0015] Further, a collection box is arranged at the lower part of one end of the driving chain close to the tensioning shaft.

[0016] The beneficial effects of the present utility model are:

[0017] By arranging a photoelectric sensor group on the outer side of the drive chain, the surface state of the packaging tube can be monitored in real time. When defects such as misaligned tube caps, deformed tube bodies, or surface scratches are detected, the photoelectric sensor group transmits the detection data to the controller. The controller adjusts the rotational speed of the servo motor in real time according to the detection data, and controls the removal unit one and the removal unit two to remove the defective packaging tubes, so that the speed of the drive chain transmission is synchronized with the action of removing the defective packaging tubes, avoiding the pause of the drive chain caused by the removal action, ensuring the continuous conveying efficiency of normal packaging tubes, and at the same time avoiding the missed detection problem caused by the detection blind area of a single group of sensors, and preventing unqualified products from flowing into the subsequent processes.

[0025] The present utility model will be specifically described and illustrated below in conjunction with the embodiments.

[0026] Embodiment 1

[0027] As Figures 1-5As shown in the figure, the effervescent tablet packaging tube conveying and detecting device of the present utility model includes a transport chain 1, a driving chain 2 is cooperatively arranged on the transport chain 1, a driving shaft 3 is arranged at one end of the driving chain 2, a tensioning shaft 11 is arranged at the other end of the driving chain 2, a controller 4 is arranged outside the transport chain 1, a photoelectric sensor group 5 is arranged on the side of the controller 4 close to the transport chain 1, a removal unit one 6 and a removal unit two 19 are arranged on the top of the controller 4, electric push rods 7 are arranged on both the removal unit one 6 and the removal unit two 19, a vacuum adsorber 8 is arranged on the electric push rod 7, a servo motor 10 is arranged at one end of the driving shaft 3, and the controller 4 is electrically connected to the photoelectric sensor group 5, the removal unit one 6, the removal unit two 19, the vacuum adsorber 8 and the servo motor 10 respectively. By means of the photoelectric sensor group 5, the surface state of the packaging tube is monitored in real time, and the controller 4 adjusts the conveying speed of the driving chain 2 and controls the operation of the removal unit one 6 and the removal unit two 19 to ensure the continuous conveying efficiency of the packaging tube.

[0028] An electric telescopic rod 13 is arranged at the bottom of the vacuum adsorber 8, and a flexible suction pipe 14 is arranged inside the electric telescopic rod 13.

[0029] One end of the electric telescopic rod 13 away from the vacuum adsorber 8 is provided with a vacuum gripper 9, and a number of groups of suction nozzles are arranged on the vacuum gripper 9. When the electric telescopic rod 13 extends to make the vacuum gripper 9 contact the packaging tube, multiple groups of suction nozzles can be evenly distributed on the surface of the packaging tube to provide balanced adsorption force, ensuring that the vacuum gripper 9 can stably hold the packaging tube.

[0030] One end of the flexible suction pipe 14 is communicated with the vacuum adsorber 8, and the other end of the flexible suction pipe 14 is communicated with the vacuum gripper 9. The flexible suction pipe 14 provides a stable gas transmission channel for vacuum adsorption. When the vacuum adsorber 8 evacuates, it can quickly extract the air in the vacuum gripper 9, so that the adsorption force of the vacuum gripper 9 rises rapidly.

[0031] The photoelectric sensor group 5 includes a photoelectric sensor one 501, a photoelectric sensor two 502 and a photoelectric sensor three 503. The photoelectric sensor one 501, the photoelectric sensor two 502 and the photoelectric sensor three 503 are evenly arranged on the controller 4 along the movement direction of the driving chain 2.

[0032] The removal unit one 6 and the removal unit two 19 are respectively arranged on the top of the controller 4 in cooperation with the photoelectric sensor two 502 and the photoelectric sensor three 503.

[0033] The controller 4 is provided with a touch screen 16 and an alarm 17, and both the touch screen 16 and the alarm 17 are electrically connected to the controller 4. The photoelectric sensor I 501 can timely detect defects such as cap misalignment, tube body deformation or surface scratches during the transportation of the packaging tube, and transmit the detection data to the controller 4. The controller 4 adjusts the rotation speed of the servo motor 10 in real time according to the detection data; the photoelectric sensor II 502 cooperates with the removal unit I 6. After the photoelectric sensor I 501 detects a defect, it can accurately locate the position of the defective packaging tube and timely control the removal unit I 6 to remove it; the photoelectric sensor III 503 cooperates with the removal unit II 19. If it is found that there are still defective packaging tubes not removed, the removal unit II 19 can locate and remove them again, forming a double guarantee mechanism, improving the removal accuracy of defective packaging tubes, and ensuring that unqualified products will not flow into the subsequent processes; when the photoelectric sensor III 503 detects that there are still defective packaging tubes and they are not removed by the removal unit II 19, the alarm 17 will immediately trigger an alarm to remind the operator to quickly take corresponding measures to ensure the normal progress of production.

[0034] A support shaft 12 is arranged between the tensioning shaft 11 and the driving shaft 3. The support shaft 12 reduces the vibration of the driving chain 2 and ensures the stable transportation of the packaging tube.

[0035] A recycling box 15 is arranged on the outer side of the transport chain 1 away from the controller 4.

[0036] A collection box 18 is arranged at the lower part of one end of the driving chain 2 close to the tensioning shaft 11.

[0037] Working principle and process:

[0038] I. Transportation and initial detection of packaging tubes

[0039] The servo motor 10 drives the driving chain 2 to drive the packaging tube to be transported along the transport chain 1 at a preset speed.

[0040] The photoelectric sensor I 501 detects defects such as cap misalignment, tube body deformation or surface scratches of the packaging tube in real time, and transmits the detection data to the controller 4.

[0041] II. Removal of defective packaging tubes

[0042] When the photoelectric sensor I 501 detects a defective packaging tube, the controller 4 adjusts the rotation speed of the servo motor 10, and at the same time controls the removal unit I 6 and the removal unit II 19 to move to the preset position in advance and wait for triggering.

[0043] When the photoelectric sensor II 502 detects that the defective packaging tube reaches the removal unit I 6, the electric telescopic rod 13 of the removal unit I 6 extends to make the vacuum gripper 9 contact the defective packaging tube; the vacuum adsorber 8 evacuates the air, and adsorbs the defective packaging tube through the vacuum gripper 9; the electric push rod 7 moves horizontally to put the defective packaging tube into the recycling box 15.

[0044] When the photoelectric sensor three 503 detects that the defective packaging tube has not been removed, the removal unit two 19 repeats the above actions to achieve secondary removal; if the removal unit two 19 still fails to remove the defective packaging tube successfully, the controller 4 triggers the alarm 17 and controls the servo motor 10 to stop, and the operator views the abnormal data through the touch screen 16.

[0045] III. Collection of qualified packaging tubes

[0046] The qualified packaging tubes are conveyed to the end by the drive chain 2 and fall into the collection box 18.
