[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 6 As shown, one embodiment of the present invention provides a drug column pressing production system, including a material storage device, a pressing mold and an automatic grabbing and placing mechanism, the material storage device is used to place the drug cover; the automatic grabbing and placing mechanism includes a transverse mechanism 2, a lifting mechanism and a material picking mechanism 6, the material picking mechanism 6 is installed on the lifting mechanism and is higher than the material storage device, the lifting mechanism is installed on the transverse mechanism 2, and is used to drive the material picking mechanism 6 to move up and down to approach or move away from the material storage device; the material picking mechanism 6 has a first station and a second station, when the material picking mechanism 6 is in the first station, the material picking mechanism 6 is located above the material storage device; when the material picking mechanism 6 is in the second station, the material picking mechanism 6 is located above the pressing device. Above the mold; the transverse movement mechanism 2 is used to drive the material picking mechanism 6 to switch between the first station and the second station; the material picking mechanism 6 includes a top plate 601, a negative pressure device and at least one grabbing member, the top plate 601 is installed at the bottom end of the lifting mechanism, and the grabbing member is installed on the top plate 601; the grabbing member includes a connected negative pressure tube 602 and an adsorption head 604, the top end of the negative pressure tube 602 is installed on the top plate 601, and the top opening of the adsorption head 604 is connected to the bottom opening of the negative pressure tube 602; the negative pressure device is connected to the top opening of the negative pressure tube 602, and is used to extract the air inside the negative pressure tube 602 to form a negative pressure environment inside the negative pressure tube 602.

[0031] In this embodiment, grabbing points corresponding to the grabbing members are divided on the table of the material storage device, and the worker places a plurality of stacked and nested medicine blister 10 on the grabbing points to be grabbed by the material taking mechanism 6. When the transverse movement mechanism 2 drives the material taking mechanism 6 to move to the first station, the grabbing points are located directly below the corresponding grabbing members.

[0032] In the initial state, the material-retrieving mechanism 6 is located directly above the material storage device. The worker places the stacked multiple medicine caps 10 on the grabbing point on the material storage device. At this time, the adsorption head 604 in the grabbing member is located directly above the medicine caps 10. The grabbing member on the top plate 601 is driven by the lifting mechanism to move to the set height toward the material storage device, so that the adsorption head 604 fits exactly onto the topmost medicine cap 10. Then the negative pressure device extracts the air inside the negative pressure tube 602 to make the inside of the negative pressure tube 602 and the adsorption head 604 a negative pressure environment. The adsorption head 604 thus adsorbs the topmost medicine cap 10. Then the lifting mechanism raises the grabbing member to a fixed height, and then the transverse mechanism 2 drives the lifting cylinder 5 and the material-retrieving mechanism 6. After moving horizontally for a fixed distance, the picking mechanism 6 just moves to the second station. At this time, the grabbed medicine cap 10 is just located above the mold cavity of the pressing mold. Then the lifting mechanism drives the grabbed medicine cap 10 to descend to place the medicine cap 10 into the mold cavity. Finally, the negative pressure device stops working, and the adsorption head 604 puts down the sucked medicine cap 10, and the medicine cap 10 is placed in the mold cavity. Then the transverse movement mechanism 2 is reset, so that the picking mechanism 6 is reset to the first station again, waiting for the next command.

[0033] It can be seen that the drug column pressing production system realizes the automated grabbing and placing operation of the drug cap 10 in the drug column pressing production, can accurately place the drug cap into the mold cavity of the pressing mold, can ensure that the posture of the drug cap is correct and without deviation, reduces the labor intensity of workers, improves production efficiency, and enhances production reliability and safety.

[0034] As a preferred embodiment, Figure 1 As shown, the drug column pressing production system includes a stand 1, a material storage device and a pressing mold arranged in sequence, the stand 1 is located behind the material storage device, the transverse mechanism 2 is horizontally installed on the top of the stand 1, the lifting mechanism is vertically installed on the transverse mechanism 2, and the material picking mechanism 6 is installed at the bottom of the transverse mechanism 2. The transverse mechanism 2 is used to drive the lifting mechanism and the material picking mechanism 6 to move horizontally together, and the lifting mechanism is used to drive the material picking mechanism 6 to move up and down. When the transverse mechanism 2 drives the material picking mechanism 6 to move to the first station, the material picking mechanism 6 is located directly above the material storage device; when the transverse mechanism 2 drives the material picking mechanism 6 to move to the second station, the material picking mechanism 6 is located directly above the pressing mold.

[0035] Exemplarily, the lifting mechanism is any one of an air cylinder, an oil cylinder, and a linear module, as long as it can drive the material taking mechanism 6 to rise and fall, and no specific limitation is made. In this embodiment, a lifting cylinder 5 is selected, and a connecting seat 4 is fixedly installed on the top of the lifting cylinder 5, and the connecting seat 4 is fixedly connected to the transverse movement mechanism 2.

[0036] For example, Figure 1As shown, six grabbing members are provided, and the six grabbing members are divided into two rows, and each row has three grabbing members, so that six medicine-shaped caps 10 can be grabbed at one time, thereby ensuring production efficiency.

[0037] It should be noted that the number of the gripping members on the top plate 601 is determined by the number of mold cavities of the mold. In this embodiment, six gripping members are provided. In some feasible embodiments, eight, ten, etc. gripping members may be provided.

[0038] As a preferred embodiment, in order to ensure that the medicine liner 10 is grasped and its posture is correct without deviation, a guide cover 603 is specially provided on the bottom outer cover of the negative pressure tube 602, the lower surface of the guide cover 603 is lower than the negative pressure tube 602, and the adsorption head 604 is located in the internal space of the guide cover 603, and the adsorption head 604 and the guide cover 603 are coaxial. The bottom end of the guide cover 603 has a conical surface adapted to the medicine liner 10, and the posture of the medicine liner 10 is adjusted by the conical surface. Specifically, when the medicine liner 10 is grasped and grasped, the conical surface at the bottom end of the guide cover 603 first fits with the conical surface of the medicine liner 10, and the conical surface at the bottom end of the guide cover 603 uniformly applies pressure to the conical surface of the medicine liner 10, thereby adjusting the posture of the medicine liner 10, so that the posture of the adsorbed medicine liner 10 is correct, ensuring that when the medicine liner 10 is placed later, the medicine liner 10 can be placed in the mold cavity with an accurate posture.

[0039] Exemplarily, in this embodiment, the adsorption head 604 is a rubber bellows, and the adsorption head 604 has good deformation ability and can better fit the conical surface of the medicine cover 10.

[0040] As a preferred embodiment, six first circular holes are provided on the upper surface of the top plate 601 for the negative pressure tube 602 to pass through, such as Figure 4 The top of the negative pressure tube 602 is connected to a top tube 605, the diameter of the top tube 605 is smaller than the diameter of the negative pressure tube 602, and six gate-shaped plates 608 corresponding to the first circular holes on the top plate 601 are installed on the upper surface of the top plate 601, the gate-shaped plates 608 are located above the corresponding first circular holes, and a second circular hole for the top tube 605 to pass through is opened on the top of the gate-shaped plates 608. Further, a fixing nut 606 is installed on the end of the top tube 605 higher than the gate-shaped plates 608, and a spring 607 is sleeved on the top tube 605, and the spring 607 is located between the inner top wall of the gate-shaped plates 608 and the upper surface of the negative pressure tube 602.

[0041] When installing the negative pressure tube 602, first put the spring 607 on the top tube 605, then insert the top end of the top tube 605 from the bottom of the top plate 601 into the first circular hole of the top plate 601, and then continue to push the negative pressure tube 602 upward so that the top tube 605 passes through the second circular hole on the door plate 608, and finally screw the fixing nut 606 onto the top tube 605.

[0042] When the lifting cylinder 5 drives the adsorption head 604 toward the medicine cover 10 so that the conical surface at the bottom end of the guide cover 603 fits with the conical surface of the medicine cover 10, the spring 607 is in a compressed state. The spring 607 provides a buffering effect to avoid the situation where the medicine cover 10 is damaged due to excessive pressure applied by the guide cover 603 to the medicine cover 10.

[0043] For example, the negative pressure device may be a vacuum pump connected to six hoses, each of which is connected to the top opening of the corresponding top pipe 605, and each hose is equipped with a solenoid valve. The air in the negative pressure pipe 602 and the adsorption head 604 is extracted by the vacuum pump. In addition, the negative pressure device may also be a vacuum negative pressure station, a vacuum generator, etc.

[0044] As a preferred embodiment, Figure 5 and Figure 6 As shown, the material storage device includes a support base 3, a bearing platform disposed on the upper surface of the support base 3, and a plurality of storage components 7 corresponding to the grabbing members. Further, the bearing platform includes four columns 301 and a bearing plate 302, the four columns 301 are disposed at the four corners of the top surface of the support base 3, and the bearing plate 302 is disposed between the top ends of the four columns 301. The storage component 7 is mounted on the bearing plate 302, and is used to place the medicine liner 10.

[0045] Specifically, Figure 6 As shown, in descending order, the storage component 7 includes a truncated cone column 703, a material receiving column 702 and a column 701 connected in sequence, two rows of holes for the truncated cone column 703 to pass through are provided on the upper surface of the carrier plate 302, and the truncated cone column 703 is inserted into the corresponding circular hole on the upper surface of the carrier plate 302. The diameter of the truncated cone column 703 is greater than the diameter of the material receiving column 702, the truncated cone column 703, the material receiving column 702 and the truncated cone column 703 are coaxially arranged, the diameter of the material receiving column 702 is the same as the diameter of the lower surface of the truncated cone column 703, and the truncated cone column 703 matches the medicine liner 10.

[0046] In this way, when placing the drug liner 10, only one drug liner 10 needs to be placed on the truncated cone column 703. Since the truncated cone column 703 and the drug liner 10 match each other, the inner wall of the drug liner 10 and the conical surface of the truncated cone column 703 fit perfectly, so as to ensure that the posture of the drug liner 10 is correct and without deviation. Then the next drug liner 10 is placed on the drug liner 10 on the truncated cone column 703, and then stacked in this way.

[0047] To limit the position of the medicine-shaped cover 10 stacked on the truncated cone column 703, ensure that the medicine-shaped cover 10 is in a correct posture. Figure 5As shown, a plurality of limiting rods 704 are installed around each circular hole of the carrier plate 302. The limiting rods 704 are round bars, and the plurality of limiting rods 704 are evenly arranged around the axis of the circular hole, and a limiting space for maintaining the vertical stacking of the drug-type cover 10 is formed between the plurality of limiting rods 704. The bottom periphery of the stacked drug-type cover 10 is in contact with the surface of the plurality of limiting rods 704 at the same time, which can further ensure that the posture of the drug-type cover 10 is correct without deviation.

[0048] As a preferred embodiment, Figure 6 As shown, the storage device also includes a lifting mechanism 9, and the lower surfaces of the multiple cylinders 701 are simultaneously connected to the horizontal plate 901, and a circular hole is opened at the center of the horizontal plate 901. The lifting mechanism 9 includes a screw 902, a threaded sleeve, a coupling 903 and a reduction motor. The threaded sleeve is fixed in the circular hole on the horizontal plate 901, and the threaded sleeve and the screw 902 are screwed together. The top end of the screw 902 is rotatably connected to the bearing plate 302 through a bearing, and the bottom end of the screw 902 is connected to the output end of the reduction motor through a coupling 903.

[0049] It should be noted that each time the liner 10 is grabbed, the lowering height of the lifting cylinder 5 is fixed, and the jacking mechanism 9 is relied upon to raise the height of the liner 10 to adapt to the grabbing piece.

[0050] Specifically, when the topmost liner 10 among the liner 10 stacked on the truncated cone column 703 is taken away, the reduction motor rotates at a set speed for a fixed time to push the column 701 to rise to a set height, thereby pushing the liner 10 stacked on the truncated cone column 703 to rise to a set height. The rising set height is the same as the thickness of the liner 10. Thereafter, each time a liner 10 is taken away, the lifting mechanism 9 pushes the column 701 to step up once until all the liner 10 are taken away.

[0051] As an optional embodiment, Figure 6 As shown, in order to improve the stability of the horizontal plate 901 and the storage component 7 during lifting, a plurality of vertically arranged upright poles 904 are installed at the bottom of the horizontal plate 901, and a plurality of holes for the upright poles 904 to pass through are opened on the table top of the supporting base 3.

[0052] It should be noted that, considering that there is a force between two adjacent drug-shaped liners 10 among the multiple drug-shaped liners 10 stacked together, when the adsorption head 604 adsorbs the drug-shaped liners 10 on the top layer, the drug-shaped liners 10 that are in contact with the drug-shaped liners 10 on the top layer may be taken away. In order to solve this technical problem, as Figure 5 and Figure 6As shown, two support frames are installed on the upper surface of the carrier plate 302, and a plurality of anti-adhesion mechanisms 8 are evenly arranged and installed on the two support frames along the length direction thereof, and the anti-adhesion mechanisms 8 correspond to the storage components 7 one by one. The two support frames are located on both sides of the two rows of storage components 7, respectively.

[0053] The support frame includes a plurality of fixing seats 801 and a fixing plate 802 . The plurality of fixing seats 801 are installed on the lower surface of the fixing plate 802 . The fixing seats 801 are detachably installed on the upper surface of the bearing plate 302 .

[0054] In this embodiment, the anti-adhesion mechanism 8 includes a first cylinder 803 and a pressing sheet 804 connected to each other. The first cylinder 803 is installed on the lower surface of the carrier plate 302 , and a U-shaped groove for clamping the liner 10 is provided on the pressing sheet 804 .

[0055] It should be noted that the pressing sheet 804 is preferably made of a flexible material, such as copper, rubber or plastic, in order to avoid scratching the liner 10. The maximum width of the U-shaped groove on the pressing sheet 804 is slightly smaller than the maximum diameter of the liner 10.

[0056] For the convenience of description, the topmost drug cover 10 among the multiple drug covers 10 stacked on the storage part 7 is named the first drug cover, and the drug cover adjacent to the first drug cover is named the second drug cover. Before the adsorption head 604 adsorbs the first drug cover, the first cylinder 803 extends to drive the pressing sheet 804 to approach the storage part 7 until the U-shaped groove on the pressing sheet 804 slightly clamps the side of the bottom of the second drug cover 10, and then the lifting mechanism drives the adsorption head 604 to move up, thereby removing the first drug cover. In this way, there will be no situation where two or even more drug covers 10 are taken away at once, which improves the grasping accuracy.

[0057] Preferably, the present medicine column pressing production system also includes a control box, a power supply device, and the lifting cylinder 5, the first cylinder 803, the reduction motor and the traverse mechanism 2 are all connected to the control box signal, and the control box controls the entire work of grabbing and placing the medicine liner 10. The power supply device is used to supply power to each electrical component.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
