Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical manufacturing, in particular to a medicine basket buffer device. Background Art

[0002] The preparation of Chinese medicine requires different weights of Chinese medicinal materials to be prepared according to prescriptions. The manual method of preparing medicines in traditional Chinese medicine pharmacies has been gradually replaced by automated Chinese medicine dispensing systems due to its disadvantages in efficiency, accuracy, and manual workload.

[0003] The automated Chinese medicine dispensing system uses medicine containers (mainly medicine baskets) to pass through the medicine drop ports of multiple dispensing units in sequence and dispense the dropped medicines, thereby achieving automatic dispensing of each medicine in the prescription. The dispensed medicines in the medicine baskets are then bagged, and the empty medicine baskets are cached and put back on the conveyor line when needed.

[0004] The existing control method of medicine basket cache is as follows:

[0005] In the basket storage action, the long-stroke cylinders on both sides drive the support block to raise the medicine basket to the basket storage position. At this time, the cylinder opens the limit block in advance (the limit block is also pushed horizontally by the cylinders on both sides); after the medicine basket rises to the position, the cylinders on both sides extend to push the limit block to hold the medicine basket again. Then the support block moves downward to complete the basket storage action.

[0006] For the basket placing action, first the long-stroke cylinder drives the supporting block to rise to the basket storage position, and then the cylinders on both sides drive the limit blocks to retract. At this time, the supporting blocks on both sides are moved down a short distance by the short-stroke cylinders. At this time, the cylinders on both sides push the limit blocks to extend again to support the medicine basket, and finally the supporting blocks on both sides drive the medicine basket to descend again to complete the basket placing action.

[0007] The control actions of the existing medicine basket cache are all completed by the cylinder. Due to the low control accuracy of the cylinder, multiple limit blocks have asynchronous opening and closing time points and inconsistent horizontal movement displacements. At the same time, during the lifting process of the support blocks, multiple support blocks are not on the same horizontal plane. The above situation will cause the medicine basket to be unable to smoothly enter the medicine basket storage space. Utility Model Content

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] like Figure 1 As shown, a medicine basket caching device provided in this embodiment includes:

[0048] The cavity 2 is used to store the medicine basket 1;

[0049] A limit block 3 is arranged at the opening of the cavity 2, and the limit block 3 can limit the medicine basket 1 from sliding out of the cavity 2;

[0050] The driving device 4 is used to drive the limiting block 3 to move away from the opening of the cavity 2, so as to release the limiting block 3 from limiting the medicine basket 1 inside the cavity 2;

[0051] The limit block 3 is rotatably connected to the action end of the driving device 4;

[0052] When the medicine basket 1 enters the opening of the cavity 2 , the limiting block 3 can rotate toward the inside of the cavity 2 under the thrust of the medicine basket 1 , so that the medicine basket 1 enters the cavity 2 and limits the medicine basket 1 from sliding out of the cavity 2 .

[0053] The medicine basket caching device of this embodiment mainly enables the medicine basket 1 to automatically enter the cavity 2 for storage under the action of external force, and does not limit the specific shape and structure of the medicine basket 1.

[0054] The function of the limit block 3 is mainly to form a restriction at the opening of the cavity 2, at least to prevent the medicine basket 1 from leaving the cavity 2 freely. At the same time, the limit block 3 is set to be able to rotate toward the inside of the cavity 2. During the entry of the medicine basket 1, the medicine basket 1 pushes the limit block 3 to rotate to expand the opening so that the medicine basket 1 enters the cavity 2. At this time, the limit block 3 is in an upward tilted state, which can naturally form a restrictive effect on the medicine basket 1 body to separate downward from the cavity 2 (because when the medicine basket 1 moves downward, the limit block 3 will also be forced to move in the direction of restoring the initial state).

[0055] Therefore, the present embodiment first provides a medicine basket caching device that can freely allow the medicine basket 1 to enter the cavity 2 and automatically restrict the medicine basket 1 from leaving the cavity 2 after entering.

[0056] There is no restriction on the rotation mode of the limit block 3. Generally, the initial state of the limit block 3 is required to be horizontal or tilted upward so that the medicine basket 1 can more easily enter the cavity 2. There is no restriction on the driving device 4, as long as the limit block 3 can move away from the opening.

[0057] In order to make the whole action process more stable, it is generally required that the force exerted by the limit blocks 3 on the whole medicine basket 1 is balanced. Therefore, it is preferred to set at least two groups of limit blocks 3 at the opening of the cavity 2, and the whole is evenly distributed (centrally symmetrically distributed). Each group of limit blocks 3 includes at least one limit block 3, and the number is not limited. Each group of limit blocks 3 is correspondingly rotatably connected to the action end of a driving device 4. When each group of limit blocks 3 includes multiple limit blocks 3, each group of limit blocks 3 is in the same horizontal plane.

[0058] An embodiment is provided, which is provided with 4 limit blocks 3 and 2 driving devices 4; 2 limit blocks 3 are provided on each driving device 4, the 2 limit blocks 3 are located in the same horizontal plane, and the 2 driving devices 4 are arranged opposite to each other.

[0059] In practice, one driving device 4 may be configured with four or more evenly distributed driving blocks.

[0060] The following further provides a connection method between the limit block 3 and the driving device 4, that is, a rotation method of the limit block 3, as shown in detail. Figure 3 As shown:

[0061] The action end of the driving device 4 is connected to a mounting plate 41 , on which a mounting seat 42 is arranged. The limit block 3 and the mounting seat 42 are rotatably connected via a shaft 43 , which passes through the limit block 3 and the mounting seat 42 transversely.

[0062] One end of the limiting block 3 forms a protrusion 31 which is abutted by the medicine basket 1 .

[0063] It also includes a blocking structure, which abuts against the other end of the limit block 3 in a normal state. The normal state is the initial state of the limit block 3, which is a horizontal or upwardly inclined state.

[0064] This embodiment adopts a rotation method of shaft connection, which has a more stable effect compared with other rotation connection methods such as hinge connection.

[0065] The blocking structure can be an external structure or a structure on the mounting plate 41 or the mounting seat 42. Since the limit block 3 is a rotatable structure, the other end of the limit block 3 is limited by the blocking structure, so that the limit block 3 can maintain its inherent position under normal conditions.

[0066] In this embodiment, the blocking structure is preferably a cutout 44 provided on the mounting plate 41 , and the upper end surface of the limiting block 3 abuts against the top end of the cutout 44 .

[0067] When the medicine basket 1 enters the cavity 2, the protrusion 31 is pushed first, and then the limit block 3 rotates toward the inside of the cavity 2, and the medicine basket 1 continues to move toward the opening of the cavity 2. During this process, there is a possibility that the outer side of the medicine basket 1 and the corners of the limit block 3 may abut against each other.

[0068] Therefore, in this embodiment, a chamfer 32 is formed on one side of the protrusion 31 away from the cavity 2, the chamfer 32 is inclined toward the action end of the driving device 4, and the inclination angle of the chamfer 32 is set to an angle that does not abut the medicine basket 1 when rotating toward the inside of the cavity 21.

[0069] This embodiment mainly aims at setting a matching medicine basket 1 buffer device for the existing common medicine basket 1. Figure 7 Taking the medicine basket 1 shown as an example, the side wall of the medicine basket 1 at its opening extends outward to form a flange 11, and the flange 11 is the end of the medicine basket 1 that first enters the opening of the cavity 2; the opening direction of the cavity 2 is located at the bottom of the cavity 2. The longitudinal section of the medicine basket 1 is an inverted trapezoidal structure, that is, the side wall of the medicine basket 1 is in a downwardly inwardly inclined state.

[0070] In this embodiment, in actual application, the opening of the cavity 2 is vertically downward, and the medicine basket 1 is stored vertically upward from the conveyor line and placed vertically downward.

[0071] When the medicine basket 1 enters the cavity 2, the flange of the medicine basket 1 applies a thrust to the protrusion of the limit block 3, causing the limit block 3 to rotate upward. As the medicine basket 1 moves, until the flange of the medicine basket 1 and the protrusion of the limit block 3 are separated, the protrusion on the limit block 3 loses the upward thrust, and under the action of its own gravity, the protrusion of the limit block 3 begins to rotate downward. When the limit block 3 contacts the mounting plate, the entire limit block 3 stops rotating and returns to normal.

[0072] As the protrusion of the limit block 3 rotates downward, the medicine basket 1 will also fall. In order to prevent the flange of the medicine basket 1 from falling below the protrusion of the limit block 3 before the protrusion of the limit block 3 returns to its normal position, it is necessary to accelerate the downward rotation speed of the protrusion of the limit block 3 by external force.

[0073] Therefore, in order to solve the above problems, an embodiment is provided. Figure 3 As shown:

[0074] The other end of the limit block 3 is connected to the mounting plate 41 via a spring 33. The spring 33 is in a tension state at least when the limit block 3 rotates, so as to generate a force that can restore the limit block 3 to a normal state.

[0075] When the protrusion of the limit block 3 is disengaged from the flange of the medicine basket 1, the protrusion of the limit block 3 accelerates to rotate downward, so that the flange of the medicine basket 1 finally falls on the upper end surface of the protrusion of the limit block 3. The protrusion of the limit block 3 effectively limits the bottom medicine basket 1 in the cavity 2, so that the medicine basket 1 stays inside the cavity 2.

[0076] In order to install the drive device 4, an embodiment is provided, such as Figure 1 and Figure 2 As shown:

[0077] Two mounting plates 5 are symmetrically arranged below the cavity 2; and the mounting plates 5 are arranged vertically; two driving devices 4 are respectively arranged on the top of the mounting plates 5 facing each other, and the driving devices 4 are arranged horizontally, and the driving devices 4 drive the mounting plates 41 to reciprocate in a straight line direction. A group of telescopic rods 45 are also respectively arranged on both sides of the driving devices 4 between the mounting plates 41 and the mounting plates 5 to ensure the stability of the mounting plates during movement.

[0078] The driving device 4 is preferably an electric telescopic rod.

[0079] In order to move the medicine basket 1 on the conveyor line upward into the cavity 2, in the present embodiment, a lifting device is provided on the opening side of the cavity 2, and the lifting device is used to abut the medicine basket 1 and move toward the cavity 2 to deliver the medicine basket 1 into the cavity 2; the lifting device is also used to abut the medicine basket 1 that has been buffered in the cavity 2, and to support the medicine basket 1 after releasing the limit of the limit block 3, so as to take out the medicine basket 1.

[0080] An embodiment of a lifting device is provided, such as Figure 4 As shown:

[0081] The lifting device includes a lifting mechanism 61 and a supporting block 62 arranged on the lifting mechanism 61. The lifting mechanism 61 can move up and down along the opening direction of the cavity 2, and the supporting block 62 can abut the medicine basket 1; and the lifting mechanism 61 can drive the supporting block 62 to move toward the inside of the cavity 2 to at least exceed the position where the limit block 3 is located.

[0082] Before the lifting mechanism 61 drives the supporting block 62 to move upward to deliver the medicine basket 1 into the cavity 2, the supporting block 62 is located below the flange 11 of the medicine basket 1, so that the supporting block 62 faces and abuts against the flange 11 of the medicine basket 1 during the rising process.

[0083] In order to improve the stability of the lifting mechanism when carrying the medicine basket 1 up or down, an embodiment is provided, such as Figure 2 As shown:

[0084] At least two supporting blocks 62 are arranged on the lifting mechanism 61 , and all the supporting blocks 62 are distributed symmetrically with respect to the center.

[0085] The position of the supporting block 62 and the position of the limiting block 3 are staggered along the opening direction of the cavity 2 to avoid interference between the two during movement.

[0086] In this embodiment, two groups of lifting mechanisms are provided, which are respectively arranged on two mounting plates 5 and located on both sides of the conveyor line. Two supporting blocks 62 are provided, and each lifting mechanism controls one supporting block 62. The supporting block 62 and the limit block 3 are arranged on the same side. In order to ensure the linkage between the supporting block 62 and the limit block 3, the supporting block 62 moves up and down in the space between the limit blocks 3 to avoid interference with each other; wherein, the lifting mechanism 61 is a ball screw pair, which improves the control accuracy of the support block 62 rising or falling.

[0087] Since the medicine baskets 1 in the cavity 2 are stacked from top to bottom, when taking out the baskets, there may be a situation where the bottom medicine basket 1 and the second to last medicine basket 1 are attached to each other, such as Figure 8 As shown, after the two medicine baskets 1 are attached, there is a gap 12 between the flanges 11 thereof.

[0088] In order to separate the two medicine baskets, an embodiment is provided, the specific structure is as follows Figure 5 As shown:

[0089] An electromagnetic latch 63 is provided on the lifting mechanism 61, and the electromagnetic latch 63 and the supporting block 62 move up and down synchronously. In this embodiment, the lifting mechanism 61 drives the mounting bracket 51 to move, and the electromagnetic latch 63 and the supporting block 62 are both provided on the mounting bracket 51, and the electromagnetic latch 63, the supporting block 62 and the limit block 3 are all staggered.

[0090] The latch head 631 of the electromagnetic latch 63 can be inserted into the gap 12 .

[0091] The position of the electromagnetic latch 63 is set so that when the supporting block 62 abuts against the flange 11 of the medicine basket 1 , the latch head 631 faces the gap 12 between the medicine basket 1 abutted by the supporting block 62 and the adjacent medicine basket 1 .

[0092] The electromagnetic latch 63 controls the latch head 631 to move closer to or away from the gap 12 under the electromagnetic effect.

[0093] During the process of taking the basket, the latch head extends out. In this state, the latch head and the supporting block are respectively located above and below the flange of the lower medicine basket 1, and the limit block 3 is located below the flange of the upper medicine basket 1. Then the ball screw pair drives the mounting bracket to continue to move downward, the upper medicine basket 1 is fixed, and the lower medicine basket 1 moves downward under the joint action of the latch head and the supporting block, thereby realizing the separation between the two medicine baskets 1.

[0094] During the process of the medicine basket 1 entering the cavity 2, since the limit block 3 has very high requirements on the position accuracy of the medicine basket 1, the flanges of the medicine basket 1 need to contact the same position of the protrusion 31 of the limit block 3 at the same time. If there is a deviation, one of the flanges 11 will be located above the protrusion 31 and the other flange 11 will still be located below the protrusion 31, causing the medicine basket 1 to tilt and get stuck at the limit block 3.

[0095] In order to avoid the above situation, the following methods are adopted in this embodiment:

[0096] 1) On the conveyor line, a symmetrical ")("-shaped material guide plate is provided along its conveying direction to preliminarily position the medicine basket 1 and adjust the position of the medicine basket 1 to approximately the middle position of the conveyor line.

[0097] 2) In this embodiment, the supporting block 62 must face and abut against the flange 11 of the medicine basket 1 during the upward movement; the supporting blocks 62 are symmetrically arranged in two groups, and the distance between the two groups of supporting blocks 62 is greater than the distance between the tops of the medicine basket side walls at two corresponding positions, and less than the distance between the side end surfaces of the flange 11 at two corresponding positions. During the upward movement of the supporting blocks, if the position of the medicine basket is offset, one group of supporting blocks 62 abuts against the flange 11, while the other group of supporting blocks 62 cannot abut against the flange 11.

[0098] To solve this problem, an embodiment is provided. Figure 5 As shown:

[0099] A limiting piece 64 is provided on the lifting mechanism 61 , and at least one limiting piece 64 is correspondingly provided for each supporting block 62 ; preferably two limiting pieces 64 are provided in this embodiment, and are symmetrically provided at both ends of the supporting block.

[0100] The limiting pieces 64 are arranged to be inclined relative to the vertical direction, so that the two limiting pieces 64 are in an open shape facing the opening direction of the cavity 2 ; the ends of the limiting pieces 64 are located directly above the supporting block 62 .

[0101] In this embodiment, the end of the limiting plate 64 extends downwardly to the mounting plate, and with the supporting block 62 and the medicine basket 1 as reference objects, the mounting plate is arranged on the outer wall of the supporting block 62, so that the end of the limiting plate 64 coincides with the outer edge of the upper end surface of the supporting block 62; the distance between the outer edges of the upper end surfaces of the two supporting blocks 62 is consistent with the distance between the side end surfaces of the flanges 11 at the two corresponding positions.

[0102] The limiting plate 64 and the supporting block 62 move synchronously; before the supporting block 62 abuts against the flange 11 of the medicine basket 1, the limiting plate 64 first contacts the flange 11 of the medicine basket 1, and the flange 11 of the medicine basket 1 is limited by the limiting plate 64 to adjust the position of the medicine basket, so that the two supporting blocks are opposite to and abut against the flange 11 of the medicine basket 1, and the side end surface of the flange 11 and the outer side wall of the supporting block are on a vertical plane.

[0103] 3) When the support block 62 abuts against the flange 11 of the medicine basket 1, there is a gap between the side wall of the medicine basket 1 and the support block 62, which will cause the medicine basket 1 to deviate during the upward movement, and when the medicine basket contacts the protrusion 31 of the limit block 3, the medicine basket 1 is unstable as a whole, causing the medicine basket 1 to tilt. To solve this problem, an embodiment is provided, such as Figure 5 As shown:

[0104] A horizontally arranged stop bar 65 is provided on the supporting block 62; the position of the stop bar 65 is set as follows: when the supporting block 62 abuts against the flange 11 of the medicine basket 1, the stop bar 65 can abut against the outer side wall of the medicine basket 1; wherein the stop bar 65 has a contact surface 651 that fits with the outer side wall of the medicine basket 1, and the contact surface 651 is an inclined surface with the same inclination as the outer side wall of the medicine basket 1.

[0105] The stop bar 65 fills the gap between the supporting block 62 and the outer side wall of the medicine basket 1 , so that the flange of the medicine basket 1 can contact the same position of the protrusion of the limiting block 3 at the same time during the ascending process of the medicine basket 1 .

[0106] In order to protect the relevant components, an embodiment is provided, such as Figure 6 As shown:

[0107] The housing 7 includes a housing 7, which encloses all the above structures, and the housing 7 itself forms a cavity 2; a door hole 71 is provided at the bottom of the housing 7 for the conveying line of the medicine basket 1 to pass through.

[0108] The shell 7 itself forms a cavity 2 for storing the medicine basket 1, and the horizontal section of the cavity 2 is rectangular; the four inner side walls of the cavity 2 are respectively provided with a plurality of positioning strips 72, and the positioning strips 72 are respectively in contact with the four edges of the flange 11 of the medicine basket 1.

[0109] In order to prevent the medicine basket 1 from being stuck by the inner wall of the cavity 2 during the process of moving up and down in the cavity 2, an embodiment is provided as follows:

[0110] The positioning bar 72 is provided with multiple sets of rollers (not shown in the figure) from top to bottom on the surface in contact with the flange 11 of the medicine basket 1. When the medicine basket moves up and down, the sliding friction between the medicine basket and the positioning bar is converted into rolling friction, thereby preventing the medicine basket 1 from getting stuck in the cavity due to tilting.

[0111] When the medicine basket in the cavity is full, it needs to be taken out in time so that the device can continue to store the basket. Figure 1 As shown:

[0112] The shell 7 is provided with a door 73 at a position corresponding to the space for storing the medicine basket 1, which is used for manually taking out the medicine basket after it is full; or it can also be used to manually temporarily take out some medicine baskets from the cavity; it can also be used to manually replenish the baskets in the cavity when there are no medicine baskets to be taken out of the cavity.

[0113] The following is a detailed description of the process of storing and taking out the baskets of the device in combination with the above embodiments:

[0114] When you need to store baskets,

[0115] Under the action of the conveyor line, the medicine basket 1 enters the interior of the shell 7 from the door opening. The initial position of the supporting block 62 is located below the flange 11 of the medicine basket 1. The ball screw pair (lifting mechanism 61) drives the supporting block 62 to move upward. The upper end surface of the supporting block 62 contacts the lower end surface of the flange 11, applying an upward force to the flange 11, so that the medicine basket 1 is separated from the conveyor line and moves vertically upward.

[0116] When the medicine basket 1 enters the cavity 2, the flange of the medicine basket 1 applies a thrust from bottom to top to the protrusion 31 of the limit block 3, so that the protrusion 31 of the limit block 3 is lifted upward. When the flange 11 of the medicine basket 1 passes the limit block 3, the two are out of contact, the thrust received by the limit block 3 disappears, and the limit block 3 is quickly reset under the action of the spring.

[0117] At the same time, the ball screw pair (lifting mechanism 61) drives the supporting block 62 to move downward, and the external force for the medicine basket 1 to move upward also disappears. The medicine basket 1 begins to fall under the action of its own gravity, and finally the flange 11 of the medicine basket 1 falls on the upper end surface of the protrusion 31 of the limit block 3. The ball screw pair (lifting mechanism 61) drives the supporting block to continue to move downward, and the supporting block 62 and the medicine basket 1 are separated, completing the entire process of the medicine basket 1 entering the cavity 2.

[0118] When you need to take the basket,

[0119] The ball screw pair (lifting mechanism 61) drives the supporting block 62 to move upward until the medicine basket 1 in the cavity 2 is lifted upward a short distance as a whole, and then the electric telescopic rod (driving device 4) retracts, and the ball screw pair (lifting mechanism 61) drives the supporting block 62 to move downward a distance of one basket position. Under the action of its own gravity, the medicine basket 1 moves downward as a whole, so that the upper end surface of the flange of the lowest medicine basket 1 in the cavity 2 is located below the protrusion 31 of the limit block 3.

[0120] Then, the electric telescopic rod (drive device 4) and the electromagnetic latch 63 extend synchronously to clamp the flange 11 of the lowest medicine basket 1; the protrusion 31 of the limit block 3 imposes a limit on the lower end surface of the flange 11 of the penultimate medicine basket 1.

[0121] Then, the ball screw pair (lifting mechanism 61) drives the supporting block 62 to continue to move downward, and under the action of the electromagnetic latch 63, the two medicine baskets 1 are separated; the ball screw pair (lifting mechanism 61) drives the supporting block 62 to continue to move downward until the bottom of the medicine basket 1 contacts the conveyor line, and the medicine basket 1 moves forward along the conveying direction of the conveyor line.

[0122] In this embodiment, a sensing module and a control module are also included; the sensing module is used to sense whether a medicine basket 1 passes between the two supporting blocks. The sensing module is a photoelectric sensor, which is set in the direction where the medicine basket 1 passes and sends a signal.

[0123] Among them, the control module is used to receive the signal sent by the sensing module and the control command of the terminal system; the terminal system sends the command of storing or taking out the basket to the control module according to actual needs.

[0124] When the control module receives the basket storage instruction, the control module will control the lifting mechanism 61 according to the signal sent by the sensing module; if the control module does not receive the basket storage instruction, the control module will not send a control instruction to the lifting mechanism 61 according to the signal sent by the sensing module.

[0125] When the control module receives the basket taking instruction, the control module will directly control the lifting mechanism 61 and the driving device 4 .

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
