A Chinese medicine labeling machine and its control method

Abstract

This invention discloses a traditional Chinese medicine labeling machine, comprising a packaging head for outputting medicine packets, a slide, and a conveying mechanism. The conveying mechanism is located below and to the side of the packaging head, and the slide is positioned between the conveying mechanism and the packaging head. Medicine packets output from the packaging head slide onto the conveying mechanism via the slide. The machine also includes a driving mechanism rotatably connected to the slide, driving the slide to move and / or rotate between the packaging head and the conveying mechanism. The driving mechanism can drive the slide to rotate and / or move, thereby changing the drop distance to accommodate medicine packets with different dosages. For medicine packets with large dosages, the driving mechanism controls the slide to increase the drop distance; for medicine packets with small dosages, the driving mechanism controls the slide to decrease the drop distance. This avoids adverse effects of the slide on the medicine packets due to improper drop height, ensuring production efficiency and product quality for medicine packets with different dosages.

Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine equipment, specifically, it relates to a traditional Chinese medicine labeling machine and its control method. Background Technology

[0002] A Chinese medicine labeling machine is a device used to package and label the decoction of Chinese medicinal herbs after they have been boiled.

[0003] The liquid medicine is transported from the storage tank to the packaging machine head, where it is packaged and cut into medicine bags. The medicine bags fall from the packaging machine head onto the slide, and then slide down onto the conveyor mechanism under the action of gravity. The conveyor mechanism then sends the medicine bags to the labeling station for labeling.

[0004] The medicine packets fall from the packaging machine head onto the slide under gravity. The vertical distance from the packaging machine head to the slide is called the drop height. Existing Chinese medicine labeling machines all use fixed or flip-up slides, and the drop height cannot be adjusted. However, in actual production, the same Chinese medicine labeling machine will produce medicine packets with different amounts of medicine per packet, resulting in different packet lengths. For the same Chinese medicine labeling machine, the larger the amount of medicine per packet, the longer the packet length.

[0005] If the chute is close to the packaging machine head, the medicine drop height is low. Before a large quantity of medicine bags are completely sealed, the bottom of the medicine bag will already be in contact with the chute, resulting in packaging leakage, uncontrolled packaging volume, and other consequences.

[0006] If the chute is far from the packaging machine head, the medicine will fall from a greater height, creating a drop below the machine head. Small packages of medicine, after being sealed, will fall onto the chute. This drop can easily cause the packages to tilt or flip, making labeling misaligned and often resulting in the misaligned packages getting stuck in the conveyor mechanism. This causes subsequent equipment malfunctions, requiring immediate manual intervention for repair.

[0007] Only by adjusting the slide to make the drop height similar to the length of the medicine bag can the medicine bag be safely and securely fed into the conveyor mechanism.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] This invention addresses the problem that the slide of a traditional Chinese medicine labeling machine cannot be adapted to the length of medicine packs with various dosages, by providing a traditional Chinese medicine labeling machine and its control method.

[0010] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0011] A traditional Chinese medicine labeling machine includes a packaging head for outputting medicine packages, a slide, and a conveying mechanism. The conveying mechanism is located below the packaging head, and the slide is disposed between the conveying mechanism and the packaging head. The medicine packages output from the packaging head slide onto the conveying mechanism via the slide. The machine also includes a driving mechanism, which is rotatably connected to the slide and drives the slide to move and / or rotate between the packaging head and the conveying mechanism.

[0012] Furthermore, the driving mechanism includes a first telescopic driving mechanism, the slide includes a first end of the slide away from the conveying mechanism and a second end of the slide close to the conveying mechanism, the slide is inclined downward from the first end of the slide to the second end of the slide, and the driving end of the first telescopic driving mechanism is rotatably connected to the first end of the slide.

[0013] Furthermore, the labeling machine also includes a base located below the slide, and the fixed end of the first telescopic drive mechanism is rotatably connected to the base.

[0014] Furthermore, the driving mechanism also includes a second telescopic driving mechanism, the driving end of which is rotatably connected to the second end of the slide.

[0015] Furthermore, the second telescopic drive mechanism is horizontally mounted on the base, and the fixed end of the second telescopic drive mechanism is fixedly connected to the base.

[0016] Furthermore, the drive mechanism includes a first telescopic drive mechanism, a second telescopic drive mechanism, and a base disposed below the slide.

[0017] The slide includes a first end away from the conveying mechanism and a second end close to the conveying mechanism, and the slide is inclined downward from the first end to the second end.

[0018] The drive end of the first telescopic drive mechanism is rotatably connected to the first end of the slide; the other end is fixedly connected to the base.

[0019] The driving end of the second telescopic drive mechanism is rotatably connected to the second end of the slide, and the other end is rotatably connected to the base.

[0020] Furthermore, the first telescopic drive mechanism and the second telescopic drive mechanism are each equipped with a magnetic switch for monitoring the telescopic state of the first telescopic drive mechanism and the second telescopic drive mechanism.

[0021] Furthermore, the system presets target positions for slides corresponding to different single-packet drug quantities. After receiving the single-packet drug quantity information, the system determines the target position of the slide and controls the drive mechanism to adjust the slide to the target position.

[0022] Furthermore, when the amount of medicine is N1, the first telescopic drive mechanism and the second telescopic drive mechanism retract; when the amount of medicine is N2, the first telescopic drive mechanism and the second telescopic drive mechanism extend, wherein N1 > N2.

[0023] Furthermore, the magnetic switch determines the extension and retraction states of the first and second telescopic drive mechanisms, thereby determining the current position of the slide. After the control system receives the dosage information, it determines the target position of the slide, compares the target position with the current position, and determines the driving direction of the drive mechanism.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0025] 1. The drive mechanism drives the slide to move, which can change the drop height of the medicine between the slide and the packaging machine head. When producing medicine packs with different amounts of medicine, the drop height can be changed by adjusting the slide to adapt to different production needs, thereby ensuring the production efficiency and product quality of medicine packs with different amounts of medicine.

[0026] 2. The first telescopic drive mechanism is rotatably connected to the first end of the slide. When the first telescopic drive mechanism extends, it can raise the first end of the slide, making it closer to the packaging machine head and reducing the drop height to accommodate smaller drug packages. When the first telescopic drive mechanism retracts, it can lower the first end of the slide, making it farther away from the packaging machine head and increasing the drop height to accommodate larger drug packages.

[0027] 3. If the first telescopic drive mechanism is fixedly connected to the base, during the process of the first telescopic drive mechanism driving the slide to move, the second end of the slide will move vertically. When the first telescopic drive mechanism extends and the first end of the slide rises, the second end of the slide may rise and move away from the conveying mechanism to form a drop, causing the medicine bag to be impacted when it falls from the slide into the conveying mechanism, resulting in damage to the medicine bag.

[0028] When the first telescopic drive mechanism retracts and the first end of the slide descends, the second end of the slide may also descend, approaching or even pressing against the conveying mechanism, affecting the working stability of the conveying mechanism and the slide itself.

[0029] After the first telescopic drive mechanism is rotatably connected to the base, the driving direction of the first telescopic drive mechanism is constantly changed during the telescopic process, so that the slide plate rotates around the second end of the slide plate without displacement of the second end of the slide plate, thus avoiding the above-mentioned problems.

[0030] 4. After a second telescopic drive mechanism is installed at the second end of the slide, the first and second telescopic drive mechanisms work together to move the entire slide. When it is necessary to reduce the material drop height, compared to when only the first telescopic drive mechanism is used, the slide can maintain a smaller slope, avoiding the impact caused by the excessively fast downward speed of the medicine package on the slide, which would affect the quality of the medicine package.

[0031] 5. The second telescopic drive mechanism is horizontally fixed, so that the second end of the slide remains unchanged in vertical height when the slide moves as a whole, and the drop between it and the conveyor mechanism is constant, thus avoiding impact or influence on the transmission belt when the medicine bag enters the conveyor belt.

[0032] 6. One end of the second telescopic drive mechanism is rotatably connected to the base, and the other end is rotatably connected to the second end of the slide. It can drive the slide to rotate around the first end of the slide to change the material dropping height. One end of the first telescopic drive mechanism is fixedly connected to the base, and the other end is rotatably connected to the first end of the slide. It can coordinate with the second telescopic drive mechanism to move the slide as a whole. When it is necessary to reduce the material dropping height, the slide can maintain a smaller slope.

[0033] 7. The magnetic switch can monitor the specific positions of the first and second telescopic drive mechanisms, providing a basis for determining the direction of movement relative to the current position when adjusting the slide distance.

[0034] 8. By using preset data on the sluice plate position corresponding to different dosages, the labeling machine can automatically adjust the sluice plate position simply by inputting the dosage data, eliminating the need for testing and calculation each time, making it convenient and fast.

[0035] 9. When the amount of drug is large, the first and second telescopic drive mechanisms retract, increasing the drug drop height; when the amount of drug is small, the first and second telescopic drive mechanisms extend, decreasing the drug drop height. This achieves a match between the drug drop height and the amount of drug.

[0036] 10. Each time the slide position is adjusted, the motion data relative to the current position can be obtained after the current position of the slide is determined by the magnetic switch. There is no need to reset between each adjustment, which is faster.

[0037] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0047] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0048] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] Example 1:

[0050] like Figure 1As shown, a traditional Chinese medicine labeling machine is used for packaging and labeling the decoction of prepared Chinese medicinal herbs. The labeling machine includes a medicine storage tank 5, a packaging head 2, a conveyor 1, and a conveying mechanism 3. The conveyor 1 is located directly below the packaging head 2, and the conveying mechanism 3 is located on the side of the conveyor 1, slightly lower than the conveyor 1. The end of the conveying mechanism 3 closest to the conveyor 1 overlaps with the conveyor 1 in the vertical direction.

[0051] After the liquid medicine in the storage tank 5 is packaged and cut into medicine bags that meet the requirements by the packaging head 2, it falls into the chute 1. Under the action of gravity, the medicine bags slide down the chute 1 onto the conveying mechanism 3, and are sent by the conveying mechanism 3 to the labeling station 4 for labeling.

[0052] The vertical distance between the packaging machine head 2 and the slide 1 is called the drug drop height. The optimal drug drop height is slightly longer than the length of the medicine bag.

[0053] The slide 1 is a groove-shaped structure with open ends formed by bending the two sides of a plate. The groove opening faces upward. After the medicine bag falls into the groove-shaped structure, it slides down along the groove-shaped structure. The groove walls on both sides of the groove-shaped structure limit the movement of the medicine bag.

[0054] Preferably, the slide 1 is made of stainless steel, and the inner surface of the trough structure is mirror-finished.

[0055] The labeling machine also includes a drive mechanism, which is rotatably connected to the lower surface of the slide 1. This drive mechanism can drive the slide 1 to rotate and / or move, thereby changing the dispensing distance to accommodate different dosages of medicine packets. For medicine packets with large dosages, the drive mechanism controls the slide 1 to increase the dispensing distance; for medicine packets with small dosages, the drive mechanism controls the slide 1 to decrease the dispensing distance. This avoids the slide 1 negatively impacting the medicine packet when the dispensing height is incorrect, ensuring production efficiency and product quality for medicine packets with different dosages.

[0056] Example 2:

[0057] like Figure 2 As shown, this embodiment is an improvement based on embodiment 1.

[0058] The driving mechanism includes a first telescopic driving mechanism 6, and the slide 1 includes a first end 101 of the slide near the packaging machine head 2 and a second end 102 of the slide near the conveying mechanism 3. The slide 1 is inclined downward from the first end 101 to the second end 102.

[0059] The lower surface of the first end 101 of the slide is provided with a pair of first protrusions 9 with shaft holes. The first telescopic drive mechanism 6 is a first cylinder. The top end of the guide rod of the first cylinder is rotatably connected to the first protrusions 9 with shaft holes through a shaft.

[0060] The first telescopic drive mechanism 6 can also be an electric cylinder.

[0061] The first telescopic drive mechanism 6 is rotatably connected to the first end 101 of the slide. When the first telescopic drive mechanism 6 extends, it can raise the first end 101 of the slide, making it closer to the packaging machine head 2, and reduce the drop height to accommodate smaller drug packages. When the first telescopic drive mechanism 6 retracts, it can lower the first end 101 of the slide, making it farther away from the packaging machine head 2, and increase the drop height to accommodate larger drug packages.

[0062] Most labeling machines currently use pneumatic drive. The first telescopic drive mechanism 6 uses a cylinder, which can be integrated into the existing pneumatic system, and has good compatibility.

[0063] Example 3:

[0064] like Figure 2 , Figure 4 As shown, this embodiment is a further improvement based on embodiment 2.

[0065] The labeling machine also includes a base 8 located below the slide 1. The upper surface of the base 8 is a horizontal plane. A pair of first fixing seats 11 with shaft holes are provided on the horizontal plane. The fixing seats protrude from the horizontal plane of the base 8 and are rotatably connected to the first cylinder seat via a shaft.

[0066] If the first cylinder is fixedly connected to the base 8, during the process of the first cylinder driving the slide 1 to move, the second end 102 of the slide will move in the vertical direction. When the first cylinder extends and the first end 101 of the slide rises, the second end 102 of the slide may rise and move away from the conveying mechanism 3 to form a drop, causing the medicine bag to be impacted when it falls from the slide 1 into the conveying mechanism 3, resulting in damage to the medicine bag.

[0067] When the first cylinder retracts and the first end 101 of the slide descends, the second end 102 of the slide may also descend, approaching or even pressing against the conveying mechanism 3, thus affecting the working stability of the conveying mechanism 3 and the slide itself.

[0068] After the first cylinder is rotatably connected to the base 8, the driving direction of the first cylinder is constantly changed during the extension and retraction process, so that the slide plate 1 rotates around the second end 102 of the slide plate without displacement of the second end 102 of the slide plate, thus avoiding the above-mentioned problems.

[0069] Furthermore, the first fixed base 11 can also be configured as a fixed rod, one end of which is fixedly connected to the horizontal plane of the base 8, and the other end is rotatably connected to the cylinder seat of the first cylinder.

[0070] During operation, the engagement angle between the first cylinder and the slide plate 1 is constantly changing. Different engagement angles result in different pressures on the cylinder during extension and retraction. The first fixed seat 11 can be replaced by a fixed rod. By setting the height of the fixed rod, the range of the engagement angle between the first cylinder and the slide plate 1 can be adjusted, avoiding engagement angles that exert excessive pressure on the first cylinder, thereby reducing wear and tear on the first cylinder and extending its service life.

[0071] Example 4:

[0072] like Figure 2 , Figure 5 As shown, this embodiment is a further improvement based on embodiment 3.

[0073] The drive mechanism further includes a second telescopic drive mechanism 7, which may be a second cylinder. A pair of second protrusions 10 with shaft holes are provided on the lower surface of the second end 102 of the slide. The guide rod of the second cylinder is rotatably connected to the second protrusions 10 with shaft holes via a shaft.

[0074] Furthermore, the second telescopic drive mechanism 7 can also be an electric cylinder.

[0075] After a second cylinder is installed at the second end 102 of the chute, the first and second cylinders work together to move the chute 1 as a whole. When it is necessary to reduce the drop height, the chute 1 can maintain a smaller slope compared to when only the first cylinder is used, avoiding the impact caused by the excessively fast sliding speed of the medicine bag on the chute 1, which would affect the quality of the medicine bag.

[0076] Example 5:

[0077] like Figure 2 , Figure 5 As shown, this embodiment is a further improvement based on embodiment 4.

[0078] A pair of second fixed seats 12 are provided on the horizontal surface of the base 8. The second fixed seats 12 are respectively connected to the two ends of the second cylinder seat, and the second cylinder is horizontally fixed on the base 8. The extension and retraction direction of the guide rod is set from the base 8 to the conveying device.

[0079] The second cylinder is fixed in the horizontal direction. When the slide plate 1 is displaced as a whole, the second end 102 of the slide plate remains unchanged in vertical height, and the drop between it and the conveying mechanism 3 is constant, thus avoiding impact or influence on the transmission belt when the medicine bag is swept into the conveyor belt.

[0080] Example 6:

[0081] This embodiment is a further improvement based on Embodiment 1.

[0082] The drive mechanism includes a first telescopic drive mechanism 6, a second telescopic drive mechanism 7, and a base 8 disposed below the slide plate 1. The first telescopic drive mechanism 6 is a first cylinder, and the second telescopic drive mechanism is a second cylinder.

[0083] The slide 1 includes a first end 101 away from the conveying device and a second end 102 near the conveying device. The lower surface of the first end 101 is provided with a pair of first protrusions 9 with shaft holes, and the lower surface of the second end 102 is provided with a pair of second protrusions 10 with shaft holes.

[0084] The base 8 has a first fixing seat 11 on the side away from the conveying device and a second fixing seat 12 on the side closer to the conveying device.

[0085] The guide rod of the first cylinder is rotatably connected to the first protrusion 9 via a shaft, and the cylinder seat is fixedly connected to the base 8 via the first fixed seat 11.

[0086] The guide rod of the second cylinder is rotatably connected to the second protrusion 10 via a shaft, and the cylinder seat is rotatably connected to the base 8 via the second fixed seat 12.

[0087] Furthermore, both the first cylinder and the second cylinder can be replaced with electric cylinders.

[0088] The second telescopic drive mechanism 7 is rotatably connected at one end to the base 8 and at the other end to the second end 102 of the slide. It can drive the slide 1 to rotate around the first end 101 of the slide to change the material dropping height. The first telescopic drive mechanism 6 is fixedly connected at one end to the base 8 and rotatably connected at the other end to the first end 101 of the slide. It can coordinate with the second telescopic drive mechanism 7 to move the slide 1 as a whole. When it is necessary to reduce the material dropping height, the slide 1 can maintain a smaller slope.

[0089] Example 7:

[0090] This embodiment is a further improvement based on embodiment 5 or 6. Both the first and second cylinders are equipped with magnetic switches, which can monitor the extension and retraction states of the cylinder guide rods of the first and second cylinders.

[0091] When adjusting the position of slide 1, after determining the target position, it is generally necessary to first reset slide 1 and then adjust it to the target position. However, by determining the current position of slide 1 using a magnetic switch, the drive data for moving from the current position to the target position can be obtained, eliminating the need for resetting and making the process more convenient.

[0092] Example 8:

[0093] A control method for a traditional Chinese medicine labeling machine, employing any of the traditional Chinese medicine labeling machines described in Examples 1-7, pre-sets target positions for the conveyor 1 corresponding to different single-package medicine quantities within the labeling machine's system. After receiving the medicine quantity information, the system determines the target position of the conveyor 1 and controls the drive mechanism to adjust the conveyor 1 to the target position.

[0094] For the same Chinese medicine labeling machine, the amount of medicine per package determines the size of the medicine package. The larger the amount of medicine per package, the longer the medicine package. Once the amount of medicine per package is determined, the length of the medicine package can be determined.

[0095] By pre-setting the position data of chute 1 corresponding to different single-pack drug amounts, the labeling machine can automatically adjust the position of chute 1 simply by inputting the drug amount data, without the need for testing and calculation each time, which is convenient and fast.

[0096] Example 9:

[0097] This embodiment is an improvement based on embodiment 8.

[0098] When the dosage is N1, the guide rods of the first and second cylinders retract; when the dosage is N2, the guide rods of the first and second cylinders extend, wherein N1 > N2.

[0099] Furthermore, at least two fixed dosage specifications are set, namely "large package" and "small package". The "large package" is the maximum dosage that the sluice 1 can handle, and the "small package" is the minimum dosage that the sluice 1 can handle. When the dosage information received by the system is "large package", the guide rods of the first cylinder and the second cylinder reach the retraction limit; when the dosage information received by the system is "small package", the guide rods of the first cylinder and the second cylinder reach the extension limit.

[0100] Preferably, the control system uses solenoid valves to control the first cylinder and the second cylinder.

[0101] like Figure 3 As shown, when the first cylinder extends, it drives the slide plate 1, causing the slope of the slide plate 1 to increase rapidly, reaching... Figure 3 The solid line position of the middle slide 1 significantly reduces the drop height of the medicine bag. However, at this point, the slope of slide 1 is too large, causing the medicine bag to slide down slide 1 at a high speed. The impact on the medicine bag upon contact with the conveyor device is significant, easily damaging the medicine bag. When the first cylinder extends, the second cylinder extends simultaneously, which can move slide 1 as a whole to... Figure 3 The dashed line marks the location of the middle slide 1. From... Figure 3 As can be seen, when the drop height is the same, the slope of the slide 1 with the second cylinder moving in the same direction is significantly smaller, and the impact on the medicine bag when it slides down the slide 1 onto the conveyor device is smaller.

[0102] Example 10:

[0103] This embodiment is a further improvement based on embodiment 9.

[0104] The current position of the slide 1 can be determined by the magnetic switches installed on the first and second cylinders, and the position information is uploaded to the control system. After receiving the dosage information, the control system determines the target position of the slide 1, compares the target position with the current position, and determines the driving direction of the drive mechanism.

[0105] Furthermore, when the target position is between the current position and the conveying mechanism 3, the first telescopic drive mechanism 6 and the second telescopic drive mechanism 7 extend; when the target position is on the side away from the conveying mechanism 3, the first telescopic drive mechanism 6 and the second telescopic drive mechanism 7 retract.

[0106] Each time the position of slide 1 is adjusted, the motion data relative to the current position can be obtained after the current position of slide 1 is determined by the magnetic switch. There is no need to reset between each adjustment, which is faster.

[0107] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
