[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The present invention provides a self-locking structure, in which the installation of the locked part in the locking part is completed through the cooperation of the second spring, the first slide groove, the second slide groove and the spring sleeve, which can realize the self-locking installation of the locked part and ensure the installation reliability of the locked part.

[0039] 2. The present invention relates to a medicine collection device in which a transmission belt and a slider are driven by a pneumatic drive unit, utilizing compressed air pneumatic drive. This purely pneumatic drive, without the use of an electric device, ensures safety and reliability during the collection process. During unloading, the compressed medicine strip descends in a vertical direction. When a first proximity switch detects the compressed medicine strip, the pneumatic drive unit in the medicine collection assembly drives the transmission belt, which in turn initiates movement of the slider, suspending the compressed medicine strip on a medicine hanging rod. Because the pneumatic drive unit drives the transmission belt in stepwise rotation, the device can pause briefly, allowing the compressed medicine strip to continue descending. When a second proximity switch detects the compressed medicine strip, an external cutting device is used to cut the compressed medicine strip, completely suspending it on the medicine hanging rod. The pneumatic drive unit then drives the slider to continue movement, allowing the compressed medicine strip to be collected on the next medicine hanging rod. The present invention automates the collection process and ensures safety. Since no human intervention is required, there is no risk of harm to the operator, thereby reducing the likelihood of safety accidents.

[0040] 3. The pneumatic drive unit in the present invention adopts a stepping drive mode, so that when the compressed and stretched medicine strips are hung on adjacent medicine hanging rods, the spacing consistency can be ensured. When the medicine hanging rods stop the stepping motion driven by the pneumatic drive unit, the stopping position is accurate and reliable, and the cutting quality of the compressed and stretched medicine strips is also ensured.

[0041] 4. The present invention eliminates the need for manual intervention when collecting compressed medicine strips, thus achieving unmanned production in dangerous situations during medicine strip production and isolating humans and machines. At the same time, it prevents workers from being harmed by volatilization of harmful solvents, thus ensuring their safety.

[0042] 5. The present invention is also provided with a transfer trolley for transporting the compressed medicine strips on the hanging medicine rod, which facilitates the short-distance transportation of the compressed medicine strips collected on the hanging medicine rod, improves the entire processing flow, and ensures the safety of the entire processing flow.

[0043] 6. The pneumatic drive unit in the present invention can be driven specifically by a cam divider and is provided with an adjusting sleeve. The cam divider can ensure the stepping drive accuracy in a simple manner. By adjusting the installation height of the adjusting sleeve, the installation height of the driving wheel can be adjusted to ensure that the driving wheel and the driven wheel are located in the same installation plane.

[0044] 7. In the present invention, the driven wheel is installed on the medicine collecting machine frame through the driven wheel bearing assembly. The deep groove ball bearing can withstand the radial and axial forces of the rotating shaft during the rotation of the driven wheel, and the thrust ball bearing can withstand the axial force of the rotating shaft during the rotation of the driven wheel, ensuring that the driven wheel rotates smoothly.

[0045] 8. The present invention can ensure the installation reliability of deep groove ball bearings and thrust ball bearings by designing the specific structure of the bearing mounting seat and the specific structure of the bearing end cover. The setting of the thrust ball bearing protective cover can also protect the thrust ball bearing to prevent external debris from falling in and affecting the rotation of the driven wheel.

[0046] 9. The guide rail of the present invention is arranged in an elliptical shape, so that the entire medicine collecting device forms a circular motion mode, has a compact structure, high space utilization, can be recycled, and increases the medicine collecting capacity of the entire device.

[0047] 10. In the present invention, a first spring is provided on the slider, providing a certain cushioning effect. Furthermore, a balancing roller is provided on the slider. When the compressed and extended medicine strip is hung on the medicine hanging rod, the slider tilts toward the rod. At this time, the balancing roller abuts against the baffle, balancing the force on one side of the rod and ensuring stable movement of the slider when the compressed and extended medicine strip is hung on the rod.

[0048] 11. The medicine collecting frame of this invention is protected by sheet metal covers on all sides, which can enhance processing safety. Universal casters facilitate the movement of the device, and adjustable feet facilitate the height adjustment of the device. In addition, a curtain is installed on the transfer cart to protect the compressed medicine strips inside the cart, enhancing safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0062] In existing technology, the collection of medicines is primarily done manually, which poses safety risks and cannot guarantee the quality and consistency of the cut medicine strips. Therefore, it is necessary to replace manual labor with automated equipment in the production of pressed medicine strips. Automated equipment not only automates the collection of pressed medicine strips but also isolates humans from machines during dangerous operations, significantly reducing the harm caused by solvent evaporation.

[0063] like Figure 1As shown, the present invention proposes a medicine collecting device, which includes a medicine collecting component 1 and a transfer trolley 3.

[0064] The transport trolley 3 is used to store and transport the compressed medicine strips 2 on the medicine hanging rod 108 after being cut, and transport the compressed medicine strips 2 to the outside of the workshop. Figure 1 In the embodiment shown, two transfer carts 3 are provided. In other embodiments of the present invention, the number of transfer carts 3 can be set according to the needs of on-site processing. The transfer carts 3 are parked beside the medicine collecting assembly 1 before completing the collection of the compressed medicine strips 2. The parking position is not limited. Figure 8 As shown, the transfer cart 3 includes a frame 301, a roof panel 302, and a curtain 303. The frame 301 can be welded from 40*40 stainless steel square tubes to form the main frame 1011 of the transfer cart 3. The roof panel 302 is connected to the top of the frame 301. Curtain hanging rods 304 are provided along the four edges of the roof panel 302. The curtain 303 is mounted on the curtain hanging rods 304. The curtain hanging rods 304 are used to hang the curtain 303 to protect the compressed and stretched medicine strips 2 from exposure to the sun or rain during transportation. During transportation, the curtain 303 droops. When the transfer cart 3 is parked, the curtain 303 can be rolled up and hung on the curtain hanging rods 304. The curtain 303 and the roof panel 302 can jointly protect the compressed and stretched medicine strips 2. On the surface of the roof cover 302 close to the inside of the frame 301, multiple groups of medicine hanging rod hooks 307 are provided along the length direction of the roof cover 302, and each group of medicine hanging rod hooks 307 includes two medicine hanging rod hooks 307 located at both ends. The straight lines formed by the two medicine hanging rod hooks 307 in each group of medicine hanging rod hooks 307 are parallel to each other. After the medicine hanging rod 108 on the medicine collecting assembly 1 completes the collection of the pressed and stretched medicine strips 2, the medicine hanging rod 108 can be removed and placed on a group of medicine hanging rod hooks 307. Multiple medicine hanging rods 108 can be hung in the transfer cart 3 at the same time. The medicine hanging rod hooks 307 can be made of hard aluminum 2A12, wherein aluminum is a non-flammable material, which can ensure the safety of the medicine strips during transportation. Two universal wheels 305 are located at each of the four corners of the bottom of the frame 301, and two fixed wheels 306 are located at the other end. These fixed wheels 306 facilitate forward and backward movement of the transport cart 3. The universal wheels 305 can also be equipped with foot brakes, allowing them to be used for movement, steering, and stopping. Static-dissipating copper chains can also be installed at the bottom of the frame 301 to prevent dangerous static electricity accumulation on the transport cart 3 and to promptly conduct away any static electricity. The bottom of the frame 301 can be made of sheet metal, such as incombustible stainless steel, to prevent the pills from falling to the ground.

[0065] Before production begins, the transfer cart 3 is manually pushed into the workshop and parked in a designated area. The transfer cart 3 can be locked using the braked universal wheels 305. Once secure, the transfer cart 3 leaves the workshop. After production is complete, the transfer cart 3 is manually pushed into the workshop and, in sequence, removes the medicine hanging rods 108 with the compressed medicine strips 2 from the medicine collection assembly 1 and places them on the medicine hanging rod hooks 307 in the transfer cart 3. Typically, nine medicine hanging rods 108 can be placed on each transfer cart 3. Once the medicine hanging rods 108 are in place, the transfer cart 3 is manually pushed out of the workshop.

The driving wheel 1043 is connected to the output end of the cam divider 1047, and is driven by the cam divider 1047 to rotate in steps. The transmission belt 102 is mounted on the driving wheel 1043 and the driven wheel 1044. The driven wheel 1044 rotates under the rotation of the driving wheel 1043 and the transmission belt 102. The driven wheel 1044 is mounted on the medicine collection frame 101 via the driven wheel bearing assembly 1048. The transmission belt 102 rotates in steps along the driving wheel 1043 and the driven wheel 1044. The adjustment sleeve 1049 is mounted on the outside of the output end of the cam divider 1047. The top of the adjustment sleeve 1049 abuts against the driving wheel 1043. The height of the driving wheel 1043 can be adjusted by adjusting the installation height of the adjustment sleeve 1049 on the connecting base 1041.

The connection between the medicine hanging rod 108 and the slider 103 can be Figure 10 and Figure 11 The self-locking detachable connection method shown is that the medicine hanging rod 108 is hollow cylindrical, and a first slide groove 1081 and a second slide groove 1082 are provided on the side wall of the medicine hanging rod 108; the first slide groove 1081 is arranged axially along the medicine hanging rod 108, and the second slide groove 1082 includes a groove section 1 821 and a groove section 2 822, the groove section 1 821 extends along the circumferential outer contour of the medicine hanging rod 108, and the groove section 2 822 is arranged axially along the medicine hanging rod 108; one end of the first slide groove 1081 passes through the end face of the medicine hanging rod 108, and the other end is connected to one end of the groove section 1 821, and the other end of the groove section 1 821 is connected to the groove section 2 822; there is a smooth transition between the first slide groove 1081 and the groove section 1 821, and between the groove section 1 821 and the groove section 2 822. The slider upper cover 1031 is provided with an installation blind hole 311 for installing the medicine hanging rod 108; a second spring guide column 312 is provided at the bottom of the installation blind hole 311, and a spring sleeve 315 is provided in the installation blind hole 311 between the second spring guide column 312 and the side wall of the installation blind hole 311. The spring sleeve 315 is sleeved on the outside of the second spring 313, and one end is abutted and slidably fitted with the second spring guide column 312. The second spring 313 is sleeved on the second spring guide column 312, and the second spring 313 is located between the spring sleeve 315 and the second spring guide column 312; a limiting stopper 314 is installed on the end of the second spring guide column 312 away from the bottom of the installation blind hole 311 to prevent the spring sleeve 315 from escaping axially. When the medicine hanging rod 108 is connected to the installation blind hole 311, the end face is abutted against the end face of the spring sleeve 315.

[0070] The medicine hanging rod 108 can be made of stainless steel with a knurled surface to prevent the compressed medicine strip 2 from sliding to the ground. The slider 103 is mounted on the transmission belt 102 through the connecting block 1038. The transmission belt 102 drives the slider 103 to rotate together during the rotation process. Figure 4 and Figure 5As shown, in one embodiment of the present invention, the specific structure of the slider 103 is also optimized accordingly. The slider 103 includes a slider cover 1031, a slider body 1032, a first spring 1033, a balancing roller 1034, a mounting plate 1035, and four V-shaped rollers 1036. A pin 321 is connected to the slider body 1032. The pin 321 passes through the slider cover 1031 and extends into the mounting blind hole 311. The mounting positions of the pin 321, the first slide 1081, the groove section 1 821, the medicine hanging rod 108, and the second spring 313 satisfy the following relationship: when the medicine hanging rod 108 is pressed against the second spring 313 in the mounting blind hole 311, the pin 321 is located in the first slide 1081 and at the end of the first slide 1081 near the groove section 1 821. When installing the medicine hanging rod 108, the medicine hanging rod 108 is manually inserted into the installation blind hole 311 on the slider upper cover 1031. The medicine hanging rod 108 begins to squeeze the spring sleeve 315, and the second spring 313 is compressed. When the medicine hanging rod 108 is pushed to the limit position, the medicine hanging rod 108 is manually rotated, and the groove section 2 822 of the medicine hanging rod 108 is used to clamp on the pin 321. Under the reaction force of the second spring 313, the medicine hanging rod 108 is clamped on the pin 321 and will not fall out. When removing the medicine hanging rod 108, the medicine hanging rod 108 is first compressed into the installation blind hole 311. After being compressed to the right position, the medicine hanging rod 108 is manually rotated to disengage the medicine hanging rod 108 from the pin via the first sliding groove 1081, and then the medicine hanging rod 108 is removed from the installation blind hole 311 of the slider upper cover 1031. The slider cover 1031 and the slider body 1032 can be a split structure or an integrated structure. The following is a specific structure based on the split structure, in which the slider cover 1031 and the slider body 1032 are connected, and the medicine hanging rod 108 is detachably mounted on the slider cover 1031. The form of this detachable connection can be various, as long as it can ensure a stable installation and easy disassembly after installation. The mounting plate 1035 is installed below the slider body 1032 through the first spring guide column 1037. The first spring 1033 is mounted on the first spring guide column 1037. One end of the first spring 1033 is connected to or abuts the slider body 1032, and the other end is connected to or abuts the mounting plate 1035, which acts as a buffer and shock absorber during the movement of the slider 103. The four V-shaped rollers 1036 are all mounted on the bottom of the slider body 1032, between the mounting plate 1035 and the slider body 1032. The four V-shaped rollers 1036 are arranged in a rectangular shape. The V-shaped surfaces of the V-shaped rollers 1036 are adapted to the guide rail 105, so that the slider 103 can move along the guide rail 105 under the drive of the pneumatic drive unit 104, thereby driving the medicine hanging rod 108 to move along the guide rail 105. In addition, after the compressed medicine strip 2 is hung on the medicine hanging rod 108, the slider 103 will tilt toward the medicine hanging rod 108, as shown in FIG. Figure 9To balance the slider 103, a baffle 1039 can be installed on the medicine collecting frame 101, and a balancing roller 1034 can be installed on the side of the slider body 1032, so that the balancing roller 1034 is located below the baffle 1039. If the compressed and stretched medicine strips 2 on the medicine hanging rod 108 are too heavy, causing the slider 103 to tilt, the balancing roller 1034 will contact the baffle 1039, allowing the slider 103 to maintain horizontal operation. Specifically, the first spring guide column 1037 can be a stepped shaft structure. The end of the first spring guide column 1037 connected to the mounting plate 1035 passes through the mounting plate 1035 and is clamped on the bottom surface of the mounting plate 1035 by a step of the first spring guide column 1037. A stop washer can also be provided between the first spring guide column 1037 and the mounting plate 1035 to ensure stable installation.

[0071] The self-locking installation structure of the above-mentioned medicine hanging rod 108 and slider 103 can also be applied to other fields. When self-locking and detachable installation is required, the self-locking installation structure of the present invention can be used, and the medicine hanging rod 108 is used as the locked part and the slider 103 is used as the locking part, and it can be promoted for use.

[0072] The guide rail 105 and the transmission belt 102 have the same configuration. The slider 103 is mounted on the guide rail 105 and is adapted to the V-shaped surface of the guide rail 105 via the V-shaped roller 1036. In this embodiment of the present invention, the guide rail 105 and the transmission belt 102 are both elliptical in shape. The driving pulley 1043 and the driven pulley 1044 are respectively located at the two ends of the long diameter of the guide rail 105. The guide assembly 203 and the driving pulley 1043 are located on the same side. The slider 103 is mounted on the elliptical rotating guide rail 105 and can only move along the guide rail 105. The elliptical guide rail 105 can be composed of two linear guide rails 105 and two circular guide rails 105. Four guide rails 105 constitute a complete elliptical guide rail 105.

[0073] The medicine collecting assembly 1 is used to collect the cut compressed medicine strips 2. At the same time, it can also cooperate with the external medicine cutting device to collect the cut compressed medicine strips 2 directly on the medicine hanging rods 108. After the compressed medicine strips 2 are cut, they are placed vertically between two adjacent medicine hanging rods 108. After the external medicine cutting device cuts the cut compressed medicine strips 2, the compressed medicine strips 2 can be placed on the medicine hanging rods 108.

[0074] In order to realize automatic cutting and collection, a first proximity switch 106 and a second proximity switch 107 are further installed on the medicine collecting rack 101, and specifically, explosion-proof photoelectric switches can be used. The first proximity switch 106 and the second proximity switch 107 are both located below the unloading point of the stretched medicine strip 2. The projection of the first proximity switch 106 on the straight line where the stretched medicine strip 2 is placed vertically is at a distance of half the length of the stretched medicine strip 2 hung on the medicine hanging rod 108 on which the stretched medicine strip 2 is about to be hung. The projection of the second proximity switch 107 on the straight line where the stretched medicine strip 2 is placed vertically is at a distance of one-quarter the length of the stretched medicine strip 2 hung on the medicine hanging rod 108 on which the stretched medicine strip 2 is hung. In addition, the first proximity switch 106 and the second proximity switch 107 are not on the same straight line. After the first proximity switch 106 detects the stretched medicine strip 2, the pneumatic drive unit 104 drives the transmission belt 102 and the slider 103 to rotate in steps. At the same time, the stretched medicine strip 2 continues to descend until the second proximity switch 107 detects the stretched medicine strip 2, and the external medicine cutting device cuts off the stretched medicine strip 2. The medicine cutting device can be arranged above the medicine collecting assembly 1, and is located next to the medicine collecting assembly 1. After the compressed medicine strip 2 is unloaded, it falls vertically between two adjacent medicine hanging rods 108. When the compressed medicine strip 2 falls vertically for a certain length, the first proximity switch 106 on the medicine collecting frame 101 of the medicine collecting assembly 1 detects that the compressed medicine strip 2 is in place, and the medicine collecting assembly 1 begins to step under the drive of the pneumatic drive unit 104. The medicine hanging rods 108 in the medicine collecting assembly 1 hang the drooping compressed medicine strip 2. After a short stay, the compressed medicine strip 2 forms an S-shaped bend. The second proximity switch 107 in the middle of the medicine collecting assembly 1 detects the bent compressed medicine strip 2, and the external medicine cutting device can start to operate, completing the cutting of multiple medicine strips. The stretched medicine strips 2 are completely hung on the medicine hanging rods 108. At the same time, the stretched medicine strips 2 continue to fall, and the medicine collecting component 1 continues to rotate, reciprocating in sequence, so that the medicine hanging rods 108 of the medicine collecting component 1 hang the stretched medicine strips 2 one by one. After the production is completed, the operator enters the workshop, removes the medicine hanging rods 108 from the medicine collecting component 1 and places them on the transfer cart 3. The operator moves the transfer cart 3 with the stretched medicine strips 2 to the outside of the workshop, completing the collection and transfer operation of the stretched medicine strips 2.

[0075] The working process of the pneumatic drive unit 104 and the medicine cutting device can be completed in conjunction with the corresponding electrical control system. A corresponding video monitoring system can also be configured in the workshop to perform process monitoring and environmental monitoring. As for the medicine cutting device, an existing medicine cutting device can be used, or it can be combined with the existing manual medicine cutting method.

[0076] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
