Technical Field

[0001] This invention relates to the field of capsule machine technology, and more particularly to a hollow capsule separation and arrangement machine. Background Technology

[0002] In the production of hard capsule formulations, empty capsules are assembled from capsule caps and capsule bodies. In order to meet the processing needs of multiple subsequent processes such as filling, drying, and mixing of multiple materials, it is necessary to first achieve high-precision and non-destructive separation of the capsule caps and capsule bodies of the empty hard capsules, and then arrange the capsule bodies in an orderly manner in the empty capsule body collection orifice plate to ensure the accurate implementation of subsequent processes.

[0003] Existing capsule separators can only separate the capsule caps and lack the functions of high-precision arrangement and positioning of capsules and automatic feeding of the perforated plate. Therefore, there is an urgent need for a special equipment that combines the functions of orderly arrangement of capsules and automatic positioning of the perforated plate to solve the problems of poor adaptability and low efficiency of existing technologies. Summary of the Invention

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example Please refer to Figures 1-6 A hollow capsule separating and arranging machine includes a machine body 1, on which a perforated plate feeding mechanism 2, a capsule separating mechanism 3 and a discharge plate 4 are sequentially arranged. The perforated plate feeding mechanism 2 includes a feeding platform 20, a loading frame 21, a perforated plate body 22, a feeding motor 23, and a conveyor belt 24. The loading frame 21 is set on the feeding platform 20 and is used to stack the perforated plate body 22. The feeding motor 23 drives the conveyor belt 24 to transport the perforated plate body 22. The feeding motor 23 is a stepper motor and is fixed to the side of the machine body 1. Its output shaft is connected to the drive roller of the conveyor belt 24 through a coupling. By driving the conveyor belt 24 to run intermittently in the horizontal direction, the perforated plate body 22 is accurately transported piece by piece. The surface of the conveyor belt 24 is provided with an anti-slip rubber layer and a positioning edge. The positioning edge is attached to the side of the perforated plate body 22 to prevent the perforated plate from shifting during the transport process. The perforated plate body 22 is a rectangular plate with multiple capsule collection holes (hole diameter = capsule diameter + 0.2mm) evenly opened on it, penetrating through the upper and lower surfaces. The spacing between adjacent collection holes corresponds one-to-one with the spacing of the clamp holes 316. The capsule separation mechanism 3 includes a capsule chamber 30. A turning block 31 is located at the bottom of the capsule chamber 30. Multiple guide rails 311 are located inside the turning block 31. A transverse fork 312 is located on the bottom back side of the guide rails 311, and a vertical fork 313 is located on the outer side of the transverse fork 312. The vertical fork 313 is fixedly connected to the side wall of the turning block 31 away from the transverse fork 312 and is a hollow rectangular cavity structure. Its feed end is sealed and connected to the quantitative discharge port of the capsule chamber 30 to ensure that all capsules enter the internal channel. Multiple guide rails 311 are arranged parallel inside the turning block 31. The guide rails 311 are downwardly inclined arc-shaped grooves of 15°~20°. The groove width adopts a three-segment gradual design (feed section = capsule cap diameter + 0.5~1mm, transition section linearly reduces, discharge section = ...). The capsule body diameter is +0.1~0.3mm. Gravity drives the capsule to roll naturally. A transverse fork 312 is vertically fixed to the bottom back side of the guide rail 311. The transverse fork 312 consists of multiple parallel metal fork teeth, with a tooth spacing equal to the capsule length plus 1~2mm. This fork is used to confine the capsule to a single row of rolling, completely preventing stacking or jamming. A vertical fork 313 is provided on the outer side of the transverse fork 312. Both the transverse fork 312 and the vertical fork 313 have spoon-shaped ends, with smooth arc surfaces on the inner sides of their fork claws (arc radius = capsule cap radius + 0.1~0.3mm). (0.2~0.5mm), the scoop mouth faces the transition section of guide rail 311, the scoop bottom is connected to the discharge section of guide rail 311, the vertical fork 313 is fixedly connected to the inner wall of the turning block 31 away from the horizontal fork 312 by bolts, its installation height is flush with the end of the transition section of guide rail 311, forming a posture screening channel, the bottom of the horizontal fork 312 is provided with a drive seat 314, the drive seat 314 is a hollow shell structure, the inside is provided with an electromagnet, a return spring and a guide rod, the electromagnet is electrically connected to an external controller to control the on and off, the outside of the drive seat 314 is provided with a clamp 315, the clamp 315 is located directly below the vertical fork 313, the gap between the forks of adjacent horizontal forks 312 is provided with a partition plate 317, the clamp 315 is located below the vertical fork 313, the clamp 315 is located below the vertical fork 313, the gap between the forks of adjacent horizontal forks 312 is provided with a partition plate 317, the clamp 315 is located below the vertical fork 313, the clamp 315 is located below the vertical fork 313, the clamp 315 is located below the vertical fork 312 ... The internal part of clamp 315 has multiple clamping holes 316. The clamp 315 slides with the guide rod in the drive seat 314 to ensure vertical lifting accuracy. The clamp 315 is located directly below the vertical fork 313, and its horizontal position corresponds one-to-one with the discharge section of the guide rail 311. The gap between the forks of adjacent transverse forks 312 is vertically provided with partition plates 317. The partition plates 317 are thin steel plate structures. The top of the partition plates fits with the bottom of the turning block 31 and the bottom extends to the top of the clamp 315. They are used to separate the capsule cap and capsule body after separation to prevent them from mixing. The internal part of clamp 315 has multiple clamping holes 316 evenly opened in the horizontal direction. The clamping holes 316 are composed of two semi-circular arc holes, which form a complete circular through hole when closed (diameter = capsule body diameter + 0.05~0.1mm) to ensure stable clamping and no damage to the capsule.

[0016] As a preferred technical solution in this embodiment, a lifting cylinder 32 is provided on the side of the turning block 31 away from the loading mechanism 2 on the perforated plate. The lifting cylinder 32 is used to control the lifting and lowering of the turning block 31. The lifting cylinder 32 is vertically fixed on the bracket of the machine body 1. The top of its piston rod is fixedly connected to the side wall of the turning block 31 through a connecting seat. The lifting cylinder 32 drives the turning block 31 to rise and fall in the vertical direction, so that the discharge end of the guide rail 311 and the lower clamp hole 316 are always accurately aligned. As a preferred technical solution in this embodiment, the turning block 31 is used to guide the capsule to roll and adjust its orientation. The guide rail 311, the lateral fork 312 and the vertical fork 313 cooperate to form a capsule orientation channel to sort and correct the posture of the capsules. The lateral fork 312 restricts the stacking of capsules, the gradient groove width of the guide rail 311 forces the capsules to adjust their posture, and the vertical fork 313 guides the capsules to roll through a smooth arc surface. The three work together to sort and correct the posture of the capsules, so that all capsules are in a uniform posture of "cap facing up and capsule body facing down". As a preferred technical solution in this embodiment, the clamp 315 is divided into front and rear parts. The two parts open and close relative to each other under the electromagnetic drive of the drive seat 314 to achieve clamping and releasing of the capsule body. Both parts are fixedly connected to the electromagnet core inside the drive seat 314 and achieve relative opening and closing under the electromagnetic drive of the drive seat 314: When the electromagnet is energized, the core drives the front and rear parts of the clamp to attract each other, and the clamp hole 316 closes to clamp the capsule body; when the electromagnet is de-energized, under the elastic force of the return spring, the front and rear parts of the clamp separate and release the capsule body. This electromagnetic control method achieves rapid response (response time ≤ 0.1s) and precise control of clamping and releasing actions. As a preferred technical solution in this embodiment, the perforated plate body 22 stacked in the loading frame 21 is transferred to the surface of the conveyor belt 24 by a screw conveyor. The bottom of the loading frame 21 is provided with a screw conveyor assembly linked with the feeding motor 23. The screw of the screw conveyor assembly is set in the horizontal direction. When rotating, the screw thrust pushes the bottom perforated plate body 22 out of the loading frame 21 and smoothly transfers it to the positioning stop of the conveyor belt 24, realizing automatic single-piece feeding of the perforated plate and avoiding manual intervention. As a preferred technical solution in this embodiment, the clamp 315 is electromagnetically controlled by the drive seat 314 to clamp and release the capsule. When the capsule exits from the discharge end of the guide rail 311 with the cap facing up and the capsule body facing down, the capsule cap is limited by the bottom end face of the turning block 31, and the capsule body protrudes downward into the clamp hole 316. At this time, the electromagnet is energized, and the clamp 315 closes to clamp the capsule body. Then, the drive seat 314 drives the clamp 315 to move downward along the capsule body via a cylinder or lead screw, realizing the non-destructive separation of the capsule cap and the capsule body. The separated capsule body falls into the perforated plate body 22 on the conveyor belt 24. The perforated plate body 22, which has been filled, is conveyed by the conveyor belt 24 to the receiving plate corresponding to the discharge plate 4. At the workstation, the capsule cap is stopped by the turning block 31, and the capsule body is forcibly pulled down to achieve non-destructive separation. After separation, the capsule body moves with the clamp 315 to a preset position above the perforated plate body 22. The electromagnet is de-energized and the clamp is released. Under the action of gravity, the capsule body falls into the capsule collection hole of the perforated plate body 22 on the conveyor belt 24. The perforated plate body 22, which has completed filling, is moved to the receiving station corresponding to the discharge plate 4 under the drive of the conveyor belt 24. The discharge plate 4 is an inclined guide plate, which makes it easy for the perforated plate body 22 filled with capsules to slide out for collection.
