Description

Technical Field

[0001] The present invention relates to the technical field of labeling equipment, and in particular to a labeling machine. Background Art

[0002] As we all know, the conditions of patients who go to the hospital for treatment are different, so the types and dosages of medicines used by each person are naturally different. For patients who need infusion, in order to distinguish the liquid medicine required by each patient, the hospital must attach corresponding labels on each infusion bag (the content on the label contains the patient's information, and may also contain information such as the name of the medicine, dosage, etc.).

[0003] In the labeling machine in the prior art, since the infusion bag itself has an irregular shape and is easily deformed after being pressed, and the robot arm that controls the movement of the labeling head performs the same labeling movement each time, in order to accurately stick the label on the infusion bag, the user must place the materials in a regular pattern when loading, which is troublesome and has a low fault tolerance rate. In addition, the labeling machine does not have the function of identifying whether the information of the infusion bag with the label is consistent with the information on the label extracted by the labeling head, which can easily lead to confusion of the infusion bag information and medical accidents.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1 - Figure 3 As shown, an embodiment of the present invention provides a labeling machine, including a conveying component, a visual system 1, a manipulator 2 and a labeling head 3; the conveying component includes a labeling area, the visual system 1 is arranged above the labeling area and can detect the information and position of the infusion bag, the manipulator 2 is arranged beside the conveying component, and the labeling head 3 is installed on the manipulator 2 and can stick the label on the infusion bag under the drive of the manipulator 2.

[0031] The labeling machine provided in an embodiment of the present invention includes a conveying component, a visual system 1, a manipulator 2 and a labeling head 3; wherein the conveying component is used to transport infusion bags, the visual system 1 is arranged directly above the labeling area, the manipulator 2 is installed next to the conveying component and can move the labeling head 3 according to the information detected by the visual system 1 to accurately stick the label on the infusion bag.

[0032] Specifically, when in use, the staff can place the infusion bag irregularly at the front end of the conveying component. Then, the conveying component transports the infusion bag to the labeling area. The visual system 1 detects the specific position of the infusion bag in the labeling area and confirms the information of the infusion bag. After confirming that the infusion bag information is correct, the robot 2 moves the labeling head 3 that has extracted the label to the infusion bag position to complete the label sticking operation.

[0033] During each labeling operation, the robot 2 can accurately move the labeling head 3 to the position of the infusion bag according to the position of the infusion bag detected by the visual system 1, ensuring that the label is accurately affixed to the infusion bag, thereby reducing the workload of the staff and improving the accuracy of labeling of the infusion bag; in addition, the visual system 1 can detect the information of the infusion bag to ensure that the information on the label extracted from the labeling head 3 is consistent with the infusion bag information, thereby reducing the probability of medical accidents.

[0034] Specifically, this embodiment also provides the following detailed introduction to the specific structure of the labeling machine.

[0035] First, this embodiment further includes a printer 4 disposed beside the conveying component, and the robot 2 can drive the labeling head 3 to extract the labels printed by the printer 4 .

[0036] Specifically, when the infusion bag is placed at the front end of the conveying component, the printer 4 will print out the corresponding label according to the information input by the staff. When the conveying component transports the infusion bag to the labeling area or is about to transport it to the labeling area, the labeling head 3 will extract the printed label in advance under the control of the manipulator 2 to prepare for the subsequent labeling operation.

[0037] In this embodiment, the labeling head 3 includes a labeling head body, a movable head 31 and at least one group of one-to-one corresponding guide columns 32, springs 33 and first sensors 34; the labeling head body is installed on the manipulator 2, and the movable head 31 is slidably connected to the lower end of the labeling head body. A first connecting plate is extended from the inner wall of the labeling head body, and the first connecting plate is provided with a first through hole. A second connecting plate is extended from the inner wall of the movable head 31. The lower end of the guide column 32 passes through the first through hole and is fixedly connected to the second connecting plate. The spring 33 is sleeved on the guide column 32 and is located between the first connecting plate and the second connecting plate; the first sensor 34 is installed on the labeling head body, and the upper end of the guide column 32 can pass through the sensing area of ​​the first sensor 34.

[0038] Specifically, under the control of the manipulator 2, the labeling head 3 moves downward and makes the label at the lower end of the movable head 31 contact with the infusion bag. As the labeling head 3 continues to move downward, the interaction force between the infusion bag and the movable head 31 causes the movable head 31 to slide upward relative to the labeling head body, and the spring 33 is compressed, resulting in the interaction force between the two, so that the label can be more firmly attached to the infusion bag; finally, as the movable head 31 continues to slide, the upper end of the guide column 32 is sensed by the first sensor 34, and the manipulator 2 stops moving downward and moves the labeling head 3 upward. The labeling operation of the infusion bag is completed, and the movable head 31 is reset under the action of gravity and the rebound force of the spring 33, and can wait for the infusion operation for the next infusion bag.

[0039] During the above operation, there is no need to determine the height of the infusion bag (i.e., the infusion bag does not need to be placed regularly). Through the first sensor 34, it can be ensured that the infusion bag will not be affected by the force deformation during each labeling operation. The maximum force between the movable head 31 and the infusion bag is a set constant value, which can ensure that the label is stably adhered to the infusion bag.

[0040] Furthermore, the first sensor 34 is a slot-type sensor, and a sensing sheet capable of passing through the sensing slot of the slot-type sensor is disposed at the upper end of the guide column 32 , and the width of the sensing sheet is greater than the width of the first through hole.

[0041] The slot sensor is also called slot photoelectric switch. It is a type of through-beam photoelectric switch, also called U-type photoelectric switch. It is an infrared sensing photoelectric product, composed of an infrared transmitting tube and an infrared receiving tube. The transmitting tube and the receiving tube are installed on the two side walls of the U-shaped slot respectively. The infrared rays emitted by the transmitting tube pass through the sensing slot (U-shaped slot) and are received by the receiving tube. When the sensing sheet enters the sensing slot, the receiving tube cannot receive the infrared rays. At this time, the feedback signal will change to the control. Then the controller controls the manipulator 2 to stop driving the labeling head 3 to continue to move downward, and completes the automatic control of the downward movement distance of the labeling head 3.

[0042] In addition, in this embodiment, the sensing piece and the guide column 32 are integrally formed, and the sensing piece is similar to a rectangular structure with a long side vertically arranged. By setting its width to be larger than the diameter of the first through hole, when the lower end of the movable head 31 is not subjected to force, the relative fixation of the movable head 31 and the labeling head body is completed by the sensing piece resting on the first connecting plate.

[0043] It is worth noting that Figure 3As shown, in this embodiment, the labeling head body includes a connecting tube 35, a sensor fixing tube 36 and a fan 37. The first connecting plate is arranged on the inner wall of the connecting tube 35. The movable head 31 is sleeved on the connecting tube 35. The connecting tube 35 is detachably fixed to the lower end of the sensor fixing tube 36. The sensor is fixed on the inner wall of the sensor fixing tube 36. The fan 37 is fixed above the sensor fixing tube 36. The fan 37 can provide a negative pressure environment for the inner cavity of the movable head 31.

[0044] Preferably, in this embodiment, the guide posts 32, springs 33 and sensors are provided in four groups, and the four groups of guide posts 32, springs 33 and sensors are distributed in a regular quadrilateral. The four groups of sensors are arranged on the four inner sides of the sensor fixing cylinder 36. The four groups of guide posts 32 can guide the sliding of the movable head 31 and the connecting cylinder 35, thereby preventing the radial force between the inner wall of the movable head 31 and the outer wall of the connecting cylinder 35 from being too large, thereby causing the friction force to be too large so that the two cannot slide relative to each other, affecting the labeling operation of the infusion bag.

[0045] In addition, in this embodiment, a bottom plate 38 is detachably fixed at the bottom of the movable head 31, and a plurality of air holes are evenly arranged on the bottom plate 38. According to the size of the label to be attached, the bottom plate 38 with different air holes can be replaced in this embodiment to ensure that after the label is adsorbed on the bottom plate 38, it will not be sucked into the cavity of the movable head 31 through the air holes due to the air holes being too large.

[0046] like Figure 3 As shown, in this embodiment, a scanner 39 is fixed to the side of the labeling head body. After the labeling head 3 completes the labeling operation on the infusion bag, the scanner 39 can also scan whether the pasted label is correct to further ensure the accuracy of the infusion bag information.

[0047] Furthermore, the present embodiment also includes a frame 8, and the conveying assembly includes a first conveyor belt 5 and a second conveyor belt 6 sequentially installed on the frame 8, a loading area is provided at the front end of the first conveyor belt 5, and a labeling area is arranged on the second conveyor belt 6.

[0048] Specifically, when the infusion bag on the second conveyor belt 6 is undergoing a labeling operation, the first conveyor belt 5 can still independently transport the infusion bag, and continue to transport the infusion bag placed in the loading area toward the rear end of the first conveyor belt in sequence. After the infusion bag on the second conveyor belt 6 completes the labeling operation, the first conveyor belt 5 can quickly transport the next infusion bag to the labeling area on the second conveyor belt 6, thereby improving the labeling efficiency.

[0049] like Figure 1As shown, in this embodiment, the first conveyor belt 5 is provided with a second sensor 51 capable of sensing whether there is an infusion bag in the loading area, the rear end of the first transmission belt is provided with a third sensor 52 capable of sensing whether the infusion bag is transported to the second conveyor belt 6, and the second conveyor belt 6 is provided with a fourth sensor 61 capable of sensing whether there is an infusion bag in the labeling area.

[0050] Specifically, after the infusion bag is placed in the loading area and is sensed by the second sensor 51, the first conveyor belt 5 will start. At this time, if there is an infusion bag on the second conveyor belt during the labeling operation, if an infusion bag is moved to the rear end of the first conveyor belt 5 and is sensed by the third sensor 52, the first conveyor belt 5 will stop starting; or, if there is no infusion bag on the second conveyor belt 6, the second conveyor belt 6 and the first conveyor belt 5 will start at the same time, and the infusion bag will be directly transported to the second conveyor belt 6. After the infusion bag is transported to the labeling area and is sensed by the fourth sensor 61, the first conveyor belt 5 and the second conveyor belt 6 will pause and start the labeling operation.

[0051] Furthermore, in this embodiment, the conveying assembly also includes an electric push rod 9 and a third conveyor belt 7 serially connected to the rear end of the second conveyor belt 6, a unloading area is provided at the front end of the third conveyor belt 7, the third conveyor belt 7 is pivotally connected to the frame 8, the base of the electric push rod 9 is pivotally connected to the frame 8, and the push rod of the electric push rod 9 is pivotally connected to the third conveyor belt 7.

[0052] Specifically, the third conveyor belt 7 is in a horizontal state during normal operation, and the infusion bag can be transferred from the second conveyor belt 6 to the third conveyor belt 7. When the visual system 1 detects that the information of the infusion bag in the labeling area is inaccurate or the information on the label attached to the infusion bag scanned by the scanning gun 39 does not match the infusion bag information, after the second conveyor belt 6 transports the infusion bag to the third conveyor belt 7, the electric push rod 9 works to make the rear end of the third conveyor belt 7 tilt downward, and then the third conveyor belt 7 starts to transfer the infusion bag to the waste area.

[0053] Preferably, in this embodiment, a double-decker trolley is supported at the rear end of the third conveyor belt 7, the upper layer of the double-decker trolley is the finished product area, and the lower layer is the waste area, the rear end of the third conveyor belt 7 in a horizontal state is connected to the upper opening of the double-decker trolley, and the rear end of the third conveyor belt 7 in an inclined state is connected to the lower opening of the double-decker trolley.

[0054] Specifically, in this embodiment, a fifth sensor 62 capable of sensing whether an infusion bag is transported to the third conveyor belt 7 is provided at the rear end of the second conveyor belt 6, and a sixth sensor 71 capable of sensing whether there is an infusion bag in the unloading area is provided at the front end of the third conveyor belt 7.

[0055] After the labeling of the infusion bag is completed, or when the visual system 1 detects that the infusion bag information is inaccurate, the second conveyor belt 6 and the third conveyor belt 7 are started. When the infusion bag passes the rear end of the second conveyor belt 6, the fifth sensor 62 senses and confirms that the infusion bag has left the second conveyor belt 6, and the second conveyor belt 6 stops starting; and when the infusion bag is transported to the unloading area and is sensed by the sixth sensor 71, if the infusion bag needs to be transported to the waste area, the third conveyor belt 7 will be paused, and when the rear end of the electric push rod 9 rotates to the lower end, the third conveyor belt 7 will be restarted to complete the infusion bag transportation operation.

[0056] Finally, in this embodiment, the visual system 1 is set to be a CCD visual system, and the manipulator 2 is set to be a four-axis manipulator.

[0057] The CCD vision system is an instrument that uses CCD components to detect the appearance of an object through a display. The width of the coordinate line is 1 / 2 of similar products on the market, making the detection more accurate. At the same time, different colors of coordinate lines can be set according to the background. The general configuration can set 4 coordinate lines at the same time. The color CCD can also be used for the appearance detection of infusion bags and used as a vertical projector. The four-axis manipulator can complete the reciprocating movement of the labeling head 3 in the vertical direction and the position change from the exit of the printer 4 to the labeling area on the horizontal plane to meet the use requirements.
