Description

Technical Field

[0001] This invention belongs to the technical field of pharmaceutical packaging processing equipment, specifically relating to an automatic feeding system for pharmaceutical packaging material production. Background Technology

[0002] Our company's original automatic feeding system for pharmaceutical packaging, including pharmaceutical low-density polyethylene (LDPE) films and bags, and pharmaceutical aseptic films and bags, consisted of 12 stainless steel storage silos. Each silo needed to store a specific grade of LDPE granules. When adding raw materials after breaking open the packaging, a separate pipeline was required to avoid cross-contamination. Currently, during production, when adding different grades of raw materials after breaking open the packaging, the feeding pipeline needs to be manually switched. This is impossible for one person to operate, is time-consuming and inconvenient, and leaves the pipe openings of other silos unused for feeding open, allowing foreign objects and insects to easily enter and contaminate the raw materials in those silos. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic feeding system for the production of pharmaceutical packaging materials that features automatic switching of feeding pipelines, precise positioning, good airtightness, and cleanliness without pollution.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] An automatic feeding system for pharmaceutical packaging material production, comprising:

[0006] The base plate has multiple feeding stations evenly arranged on its upper surface along its length. Each feeding station includes a square groove on the upper surface of the base plate, and a through feeding hole is vertically opened in the center of the groove. A pressure ring is fixed at the upper edge of the feeding hole.

[0007] The feeding device can move along the length of the base plate under the drive of the driving device. It includes a transverse plate connected to the driving device. A lifting plate is provided above the transverse plate. A feeding pipe is vertically fixed on the lifting plate. A through hole corresponding to the feeding pipe is opened on the transverse plate. After the lower end of the feeding pipe passes through the through hole, a sealing ring corresponding to the pressure ring is fixed on its outer periphery.

[0008] A positioning device is installed between the feeding device and each feeding hole to position the relative position between the feeding device and each feeding hole.

[0009] There are two protective covers, located between the two ends of the feeding device and the base plate, respectively.

[0010] In one embodiment of the present invention, the positioning device includes a positioning sensor disposed between the feeding device and each feeding station.

[0011] In one embodiment of the present invention, the positioning device further includes a limiting device vertically disposed at the front and rear ends of the transverse plate, the limiting device corresponding to the corner of the groove; the limiting device includes a housing, the housing having a square cavity, the bottom of the housing having a guide hole communicating with the square cavity, a pressure sensor disposed in the square cavity, a mounting rod fixedly disposed at the lower part of the pressure sensor extending through the guide hole, a roller rotatably disposed at the lower end of the mounting rod, the roller rolling in the same direction as the length direction of the base plate, the maximum distance between the rollers on the limiting device at the front and rear ends of the transverse plate being equal to the width of the groove along the length direction of the base plate; a spring is disposed between the pressure sensor and the upper end of the square cavity, a first telescopic device is fixedly disposed at the upper center of the square cavity, the lower end of the first telescopic device is connected to a rope, the other end of the rope being fixedly connected to the pressure sensor.

[0012] In one embodiment of the present invention, when the pressure sensor is located at the lowest end of the square cavity and the first telescopic device is in a fully extended state, the rope is just in a taut state.

[0013] In one embodiment of the present invention, the positioning sensor includes a signal transmitter fixed on the transverse plate and a signal receiver disposed at each feeding station.

[0014] As one embodiment of the present invention, a dust removal device is also included. The dust removal device includes a dust removal platform disposed on one side of the feeding station on the base plate, an annular electromagnet fixed outside the pressure ring, and a sealing plate corresponding to the electromagnet. A pull-out groove corresponding to each feeding station is opened on the inner side of the dust removal platform. A pull-out plate is disposed in the pull-out groove. A second telescopic device corresponding to each pull-out groove is fixed on the outer side of the dust removal platform. The telescopic rod of the second telescopic device passes through the pull-out groove from the outer side of the dust removal platform and is connected to the pull-out plate.

[0015] In one embodiment of the present invention, the lower end of the electromagnet is flush with the lower end of the feeding pipe, the sealing plate is made of iron-containing material, and the size of the sealing plate is smaller than the size of the pull-out plate.

[0016] In one embodiment of the present invention, an exhaust trough is provided inside the dust removal platform along its length, the exhaust trough is connected to all the pull-out slots, and an air inlet pipe and an exhaust pipe are provided on the dust removal platform, which are respectively connected to both ends of the exhaust trough, and the exhaust pipe is connected to an exhaust fan.

[0017] In one embodiment of the present invention, the driving device and the dust removal table are respectively arranged on both sides of the feeding station. The driving device includes two mounting plates arranged along the length of the base plate. The two mounting plates are parallel to each other and perpendicular to the upper surface of the base plate. Mounting frames are fixed at both ends of the two mounting plates. Rollers are rotatably mounted on the mounting frames. A closed-loop belt is installed between the two rollers. One of the rollers is connected to the output shaft of a servo motor. A slide is arranged above the belt. The slide is fixed to the belt. A guide mechanism is arranged between the slide and the mounting plate.

[0018] In one embodiment of the present invention, a first dustproof groove is provided on the inner side of the upper surface of the dust removal platform along its length direction, and a long strip-shaped dustproof block is fixed on the upper surface of the base plate between the driving device and the feeding station. A second dustproof groove is provided on the upper surface of the dustproof block along its length direction. The protective cover is a guide rail bellows-type protective cover. The vertical folding parts on both sides of the protective cover are located in the first dustproof groove and the second dustproof groove, respectively. The two ends of the base plate are fixed with baffles between the dust removal platform and the dustproof block. One end of the protective cover is fixed to the transverse plate, and the other end is fixed to the end of the base plate.

[0019] The beneficial effects of adopting the above technical solution are as follows:

[0020] The automatic feeding system for pharmaceutical packaging material production provided by this invention features an ingenious structural design. A drive device moves the feeding device along the length of the base plate, aligning the feeding pipe with different feeding stations, thus achieving automatic switching of the feeding pipe. During pipe switching, dual positioning is ensured through positioning sensors and limit devices, guaranteeing precise positioning and ensuring concentricity between the feeding pipe and the feeding hole. This prevents pipe displacement during feeding, which could lead to raw material leakage or even equipment damage. The inclusion of pressure rings and sealing rings ensures good airtightness during feeding, preventing dust leakage and avoiding feeding delays.

[0021] By installing dust covers, foreign objects and insects can be prevented from entering the corresponding storage silos through the pipe openings of silos that are not being used for feeding, thus preventing contamination of the raw materials. By installing sealing plates, when the feeding device switches between different feeding positions, the sealing plates remain plugged at the discharge port at the lower end of the feeding pipe under the attraction of an electromagnet. This prevents particles or dust on the inner wall of the feeding pipe from falling into other feeding holes or onto the bottom plate when the feeding pipe moves between different feeding positions, avoiding cross-contamination between different grades of raw materials and eliminating the need for regular cleaning of dust or particles from the bottom plate.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the invention will be described clearly and completely below in conjunction with specific embodiments.

[0039] like Figures 1-11 An automatic feeding system for the production of pharmaceutical packaging materials is shown, comprising:

[0040] The base plate 1 has multiple feeding stations evenly arranged along its length on its upper surface. Each feeding station includes a square groove 2 opened on the upper surface of the base plate 1. In this embodiment, the groove 2 is square. A through circular feeding hole 3 is vertically opened in the middle of the groove 2. An annular pressure ring 4 is fixed at the upper edge of the feeding hole 3. The bottom of the feeding hole 3 is connected to the storage silo through a silo pipe. The silo pipe is divided into a straight first silo pipe 45 and a bent second silo pipe 46. Multiple first silo pipes 45 are connected to the same connecting plate 47. The connecting plate 47 is provided with feeding ports corresponding to the first silo pipes 45.

[0041] The feeding device is located above the feeding station and can move along the length of the base plate 1 under the drive of the drive device. It includes a horizontally arranged transverse plate 12 connected to the drive device. A lifting plate 16 is provided above the transverse plate 12 and can be raised and lowered by multiple automatic lifting rods 15. A feeding pipe 17 is vertically fixed on the lifting plate 16. A through hole 13 corresponding to the feeding pipe 17 is opened on the transverse plate 12. A sealing ring 14 made of rubber, silicone or brush type is provided at the edge of the through hole 13. After the lower end of the feeding pipe 17 passes through the through hole 13, a sealing ring 19 corresponding to the pressure ring 4 is fixed on its outer periphery.

[0042] A positioning device is installed between the feeding device and each feeding hole 3 to position the relative position between the feeding device and each feeding hole 3.

[0043] There are two protective covers 49, located between the two ends of the feeding device and the base plate 1 respectively.

[0044] like Figure 8 , Figure 10 and Figure 11 As shown, in this embodiment, the positioning device includes a positioning sensor disposed between the feeding device and each feeding station. The positioning sensor is a photoelectric sensor or a proximity sensor, including a signal transmitter 43 fixed on the transverse plate 12 and a signal receiver 44 disposed at each feeding station. The signal receiver 44 is disposed on the dust removal table 31 or the dustproof block 41. In this embodiment, the signal receiver 44 is disposed on the inner side wall of the dust removal table 31.

[0045] like Figure 5 , Figure 6 , Figures 8-13 As shown, the positioning device also includes limiting devices vertically arranged on the left and right sides of the front and rear ends (both ends along the length of the base plate 1) of the transverse sliding plate 12. The four limiting devices correspond to the corners of the groove 2. Since the groove 2 is square in this embodiment, the four limiting devices are located at the four corners of the square. The limiting device includes a housing 21, and a square cavity 22 is provided inside the housing 21. A square guide hole 23 communicating with the square cavity 22 is provided at the bottom of the housing 21. A pressure sensor 25 is provided inside the square cavity 22, and a guide hole 23 is fixed at the lower part of the pressure sensor 25. A square mounting rod 26 extends into the hole 23. A roller 27 is rotatably mounted at the lower end of the mounting rod 26. The roller 27 rolls in the same direction as the length of the base plate 1. The maximum distance between the rollers 27 on the limiting devices at the front and rear ends of the left and right sides of the transverse plate 12 is equal to the side length of the groove 2. A spring 24 is provided between the pressure sensor 25 and the upper end of the square cavity 22. A first telescopic device 28 is fixed at the center of the upper part of the square cavity 22. A rope 29 is connected to the lower end of the first telescopic device 28, and the other end of the rope 29 is fixedly connected to the pressure sensor 25. The feeding pipe 17 in the feeding device can be precisely positioned using four limiting devices. When all four rollers 27 in the limiting devices enter the groove 2, all four rollers 27 are in contact with the inner walls of the front and rear ends of the groove 2 (along the length of the base plate 1), and the feeding pipe 17 is perfectly aligned with the feeding hole 3. When positioning the feeding device, both the positioning sensor and the limiting device must be positioned simultaneously. If the positioning sensor finishes positioning but the limiting device has not, the feeding device is driven by a drive device to adjust its position until the limiting device completes positioning before feeding. The spacing between adjacent grooves 2 is set appropriately so that after the positioning sensor performs initial positioning, when the feeding device is finely adjusted by the limiting device, multiple rollers 27 will not enter different grooves 2.

[0046] The pressure sensor 25 is square, located at the bottom of the square cavity 22, and the rope 29 is just taut when the first telescopic device 28 is fully extended. The upper end of the housing 21 is mounted on the transverse plate 12 via a fixing plate 30.

[0047] The automatic feeding system for pharmaceutical packaging material production provided by this invention features an ingenious structural design. A drive device moves the feeding device along the length of the base plate 1, allowing the feeding pipe 17 to connect with different feeding stations, thus achieving automatic switching of the feeding pipe 17. During the switching of the feeding pipe 17, a positioning sensor and a limit device provide dual protection, ensuring precise positioning and concentricity between the feeding pipe 17 and the feeding hole 3. This prevents displacement of the feeding pipe 17 during feeding, which could lead to raw material leakage or even equipment damage. The pressure ring 4 and sealing ring 19 ensure good airtightness during feeding, preventing dust leakage and feeding delays. A dust cover 49 prevents foreign objects and insects from entering the corresponding storage hopper through the pipe opening of the hopper not being fed, thus avoiding raw material contamination. Furthermore, the protective cover 49 prevents raw material dust from contaminating the drive device, which could cause jamming and motor burnout during feeding station switching.

[0048] like Figures 1-8 , Figure 14 and Figure 15 As shown, the automatic feeding system for pharmaceutical packaging material production also includes a dust removal device. The dust removal device includes a dust removal platform 31 installed on one side of the feeding station on the base plate 1, an annular electromagnet 20 fixed to the outside of the pressure ring 4, and a sealing plate 40 corresponding to the electromagnet 20. The inner side of the dust removal platform 31 has a square pull-out groove 33 corresponding to each feeding station. A square pull-out plate 37 is installed inside the pull-out groove 33. A second telescopic device 39 corresponding to each pull-out groove 33 is fixed to the outer side of the dust removal platform 31. The telescopic rod of the second telescopic device 39 passes through the pull-out groove 33 from the outside of the dust removal platform 31 and connects to the pull-out plate 37. A clearance hole corresponding to the telescopic rod of the second telescopic device 39 is provided between the outer side of the dust removal platform 31 and the pull-out groove 33. As a further optimization, a receiving groove 38 corresponding to the sealing plate 40 is provided on the upper surface of the pull-out plate 37. As a further optimization, to achieve better sealing of the lower end of the feeding pipe 17, a silicone gasket can be installed on the upper surface of the sealing plate 40.

[0049] By setting up the sealing plate 40, when the feeding device switches between different feeding positions, the sealing plate 40 is always blocked at the discharge port at the lower end of the feeding pipe 17 under the attraction of the electromagnet 20. This prevents particles or dust on the inner wall of the feeding pipe 17 from falling into other feeding holes 3 or onto the bottom plate 1 when the feeding pipe 17 moves between different feeding positions. This avoids cross-contamination between different grades of raw materials and eliminates the need for regular cleaning of dust or particles on the bottom plate 1.

[0050] In this embodiment, the lower end of the electromagnet 20 is flush with the lower end of the feeding pipe 17. The sealing plate 40 is made of iron-containing material. The size of the sealing plate 40 is smaller than the size of the pull-out plate 37, but not smaller than the size of the electromagnet 20.

[0051] As a further optimization, an exhaust duct 34 is provided inside the dust removal platform 31 along its length. The exhaust duct 34 is connected to all the pull-out slots 33. The dust removal platform 31 is provided with an air inlet pipe 35 and an exhaust pipe 36 that are respectively connected to both ends of the exhaust duct 34. The exhaust pipe 36 is connected to an exhaust fan. The particles and dust inside the dust removal platform 31 can be periodically removed by the exhaust fan and the exhaust duct 34. When performing exhaust, the valve on the silo pipe can be closed, or a one-way valve can be installed on the silo pipe. At the same time, the particles or dust on the bottom plate 1 below the protective cover 49 can be removed.

[0052] like Figures 5-8 As shown, the drive unit and dust removal table 31 are respectively set on both sides of the feeding station. The drive unit includes two mounting plates 5 arranged along the length of the base plate 1. The two mounting plates 5 are parallel to each other and perpendicular to the upper surface of the base plate 1. Mounting brackets 9 are fixed at both ends of the two mounting plates 5. Rollers are rotatably mounted on the mounting brackets 9. A closed-loop belt 11 is installed between the two rollers. One of the rollers is connected to the output shaft of the servo motor 10. A slide block 7 is set above the belt 11. The slide block 7 is fixed to the belt 11. A guide mechanism is set between the slide block 7 and the mounting plate 5. The slide block 7 is U-shaped. Its horizontal part is fixed to the belt 11. A slider 8 is horizontally arranged on the inner side of its two vertical parts. A sliding groove 6 adapted to the slider 8 is horizontally arranged on the outer side of the mounting plate 5. The transverse plate 12 is fixed to the slide block 7.

[0053] As a further optimization, a first dustproof groove 32 is provided on the inner side of the upper surface of the dust removal table 31 along its length direction. A long strip-shaped dustproof block 41 is fixed on the upper surface of the base plate 1 between the drive device and the feeding station. A second dustproof groove 42 is provided on the upper surface of the dustproof block 41 along its length direction. The protective cover 49 is a guide rail bellows-type protective cover. The vertical folding parts on both sides of the protective cover 49 are located in the first dustproof groove 32 and the second dustproof groove 42, respectively. A baffle 48 is fixed at both ends of the base plate 1 between the dust removal table 31 and the dustproof block 41. One end of the protective cover 49 is fixed to the transverse plate 12, and the other end is fixed to the end of the base plate 1.

[0054] The automatic lifting pole 15, the first telescopic device 28, and the second telescopic device 39 are all pneumatic cylinders, hydraulic cylinders, or electric screws.

[0055] A clamp 18 is installed at the upper end of the feeding pipe 17, which is used to connect the flexible pipe to the positive pressure feeding device.

[0056] Specific implementation process:

[0057] Before feeding, the telescopic rod of the first telescopic device 28 is retracted. Under the action of the rope 29, the pressure sensor 25 and the mounting rod 26 rise. At this time, the roller 27 is located above the base plate 1 and does not contact the upper surface of the base plate 1. The sealing plate 40 is sealed at the lower end of the feeding pipe 17 under the action of the electromagnet 20.

[0058] During feeding, the feeding device is driven by the drive device to move to the feeding station. Initial positioning is performed by the positioning sensor, and precise positioning is performed by the limiting device. During precise positioning, the telescopic rod of the first telescopic device 28 is fully extended. At this time, under the action of the spring 24, the pressure sensor 25 and the mounting rod 26 move outward. When the roller 27 is in the groove 2, the reading of the pressure sensor 25 is the elastic force of the spring 24 on it. In one implementation, the spring 24 is fully extended at this time, and the reading of the pressure sensor 25 is zero. If the roller 27 does not enter the groove 2, the roller 27 will press on the upper surface of the base plate 1. At this time, the reading of the pressure sensor 25 will inevitably be greater than the reading when the roller 27 enters the groove 2, indicating that the feeding pipe 17 and the feeding hole 3 are not completely concentrically aligned. The position of the feeding pipe 17 is finely adjusted left and right by the drive device until all four rollers 27 enter the groove 2. Precise positioning is completed, and at this time the feeding pipe 17 and the feeding hole 3 are completely concentrically aligned.

[0059] The second telescopic device 39 at the corresponding pull-out slot 33 of this feeding station controls the pull-out plate 37 to extend from the pull-out slot 33 to directly below the feeding pipe 17. The electromagnet 20 is de-energized and the magnetic force disappears. The sealing plate 40 falls into the receiving slot 38 on the pull-out plate 37 under the action of gravity. The second telescopic device 39 controls the pull-out plate 37 to transport the sealing plate 40 into the pull-out slot 33.

[0060] The automatic lifting rod 15 controls the lifting plate 16 to drive the feeding pipe 17 to descend until the sealing ring 19 is pressed on the pressure ring 4, thereby achieving a seal between the feeding pipe 17 and the feeding hole 3, and then feeding is carried out through the positive pressure feeding device.

[0061] After feeding is completed, the lifting plate 16 is raised by the automatic lifting rod 15, which drives the feeding pipe 17 to rise. The telescopic rod of the first telescopic device 28 is fully retracted, and the pressure sensor 25 and the mounting rod 26 are raised. The second telescopic device 39 at the corresponding pull slot 33 of this feeding station controls the pull plate 37 to extend from the pull slot 33 to directly below the feeding pipe 17. The electromagnet 20 is energized, and the sealing plate 40 in the receiving slot 38 is resealed at the lower end of the feeding pipe 17 under the action of magnetic force. The pull plate 37 is retracted into the pull slot 33 by the second telescopic device 39.

[0062] Based on this, different grades of raw materials are fed into different feeding stations.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
