A device for continuous unpacking, unpacking and repackaging of BFS (Block Filter) medicine bottles

Abstract

This invention discloses a continuous unpacking and repackaging device for BFS (Block Frame Storage) medicine bottles, belonging to the field of packaging equipment technology. It includes: two sets of parallel material conveyor belts with a consistent transmission ratio, used to carry compatible workpieces to be processed and material packaging containers respectively; and a material storage module. This invention ensures strictly consistent transmission speeds by synchronously driving the two parallel conveyor belts via a single power source and pulley system. The power is redirected through a vertically meshing helical gear set, driving a crankshaft structure to drive a push arm in reciprocating motion. This ensures that the push arm's motion cycle perfectly matches the conveyor belt's feeding rhythm, allowing the actions of the shovel and rollers to coincide with the material position in real time when the workpiece arrives at the processing position. This improves the processing delay or misalignment problems caused by power disconnection in traditional equipment, enhances bag opening accuracy, and reduces the risk of material breakage.

Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a device for continuous unpacking and repackaging of BFS (Block Flask) continuous plate medicine bottles. Background Technology

[0002] Traditional processes rely heavily on manual operation for the unpacking, unpacking, and repackaging of BFS continuous blister packs, which is not only labor-intensive but also inefficient. Therefore, a device for continuous unpacking, unpacking, and repackaging of BFS continuous blister packs is needed.

[0003] A search revealed Chinese invention patent application CN110937172A, which proposes "a fully automatic packaging machine." This machine uses a bag-picking device to suck up a sealed bag from a lifting device, which then opens the bag via a bag-opening device. The lower end of the worktable is equipped with a bag-suction mechanism to assist the bag-opening device. The worktable also has several air holes to cooperate with the bag-suction mechanism. A conveying device transports the box to its designated position, and a pushing device removes the box from the conveying device and places it into the bag of the bag-opening device. The pushing device then pushes the box into the sealing device for sealing and delivery. This automated bag nesting and sealing of the outer packaging box changes the traditional manual processing method, resulting in high processing efficiency, reduced labor costs, and improved production efficiency, achieving highly efficient automated production.

[0004] However, in actual use, the aforementioned disclosed devices and similar existing technical solutions, because the power sources drive the feeding and processing mechanisms separately, make it difficult to ensure that the two action cycles are completely synchronized. When the workpiece to be processed arrives at the processing position, the processing execution mechanism is prone to premature or delayed action, which can lead to misalignment of opening bags and boxes. This can not only easily damage the packaging boxes and bags, but may also cause the BFS continuous plate medicine bottles to fall and break, increasing the material loss rate in the production process. At the same time, it will also slow down the overall processing rhythm and fail to meet the needs of large-scale continuous production. Summary of the Invention

[0005] The purpose of this invention is to provide a device for continuous unpacking, unpacking and repackaging of BFS (Block Filter) medicine bottles, so as to solve the problems mentioned in the background art.

The helical gear transmission assembly includes: The equipment has a stable support base with a helical gear driven by a shaft hinged inside. A belt drive wheel system is fixed between the outer end of the shaft and the outer drive shaft of the power drive motor. The shaft-driven helical gear meshes perpendicularly with the shaft-driven helical gear, and the shaft body is fixed to one end of the power transmission crankshaft.

[0008] As a further preferred embodiment of this technical solution, the material storage module includes: A material storage frame, which is used to store any type of object in the workpiece to be processed or the material packaging container, with the frame opening placed at an angle on the top surface of the material conveyor belt; Several damping adjustment levers are evenly fixed at both ends of the top and bottom of the material storage frame.

[0009] As a further preferred embodiment of this technical solution, the bearing positioning module includes: The adjustable support base has a belt drive pulley system installed in the middle of its surface and a servo drive motor installed on its back to drive the belt drive pulley system to rotate. The bottom end of the rotating support is fixed to one end of the surface of the belt drive pulley system; A belt-driven pulley system is installed on the top of the rotating support base, and a connecting rod that passes through the rotating support base is fixed between the belt-driven pulley system and the belt-driven pulley system. An electric adsorption device is installed at the top of the belt-driven pulley system, away from the connecting rod. The pneumatic adsorption device is installed on one side of the surface of the adjustable support base and is used in conjunction with the electric adsorption device to complete the opening process of the material packaging container.

The bottom of the threaded rod is fixed to the top of the corresponding belt-driven pulley system, and a workpiece positioning sleeve is fitted on the top of the threaded rod. Two electric adsorption plates are respectively inserted and installed in the retention grooves opened at both ends of the workpiece mounting arm.

[0011] As a further preferred embodiment of this technical solution, the pneumatic adsorption device includes: Place the support arm, with one end mounted on one side of the surface of the adjustment support seat; An assembly frame is screwed onto the other end of the support arm, and several electro-pneumatic adsorption plates are installed inside.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This device for continuous unpacking and repackaging of BFS (Block Flask) medicine bottles achieves synergy between material conveying and processing operations by fully synchronizing the power transmission ratio of the material conveying system to the processing module. Two parallel conveyor belts are synchronously driven by a single power source through a pulley system, ensuring that the transmission speed is strictly consistent. The power is reversed through a vertically meshing helical gear set, driving the crankshaft structure to drive the push arm in reciprocating motion. This ensures that the action cycle of the push arm is perfectly matched with the feeding rhythm of the conveyor belt, so that when the workpiece arrives at the processing position, the execution action of the shovel and roller matches the material position in real time. This improves the processing delay or misalignment problem caused by power disconnection in traditional equipment, improves the bag opening accuracy, and reduces the risk of material breakage. In addition, the material handling shovel is designed to have both cutting and pushing functions. The shovel is controlled to extend and retract through a hydraulic drive mechanism and the swing angle is constrained by a limit structure. During the bag opening operation, the shovel extends dynamically to complete the precise cutting of the packaging bag; during the bag filling stage, it remains extended and pushes the material into the packaging container with a controllable thrust. Furthermore, the material handling roller is linked to the hydraulic mechanism via a hinged arm, and the rotation angle is rigidly constrained by a limiting device. In the horizontal mode, the roller surface pushes the material back into place by rolling and squeezing, reducing surface damage. In the vertical mode, the end of the roller impacts the opening of the packaging container and maintains the open state, allowing the shovel to complete the bagging simultaneously.

[0018] 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.

[0019] Before understanding the technical solution proposed in this application, it is important to understand that the actual application scenario of this technical solution is the back-end automated packaging workshop of a pharmaceutical manufacturing enterprise, which performs batch and continuous unpacking and unpacking operations on continuous plate medicine bottles made using the blow-fill-seal (BFS) process, and completes the subsequent resealing or repackaging production process.

[0020] like Figures 1 to 6 As shown, the present invention provides a specific technical solution: a continuous unpacking, unpacking, and repackaging device for BFS (Block Filter Tablet) vials, which mainly includes the following components: Two sets of parallel material conveyor belts maintain a strictly consistent transmission speed and are used to carry the matching workpiece 2 to be processed and the material packaging container 16, respectively. The two sets of conveyor belts are symmetrically arranged in structure to ensure the synchronicity and stability of the material during the conveying process.

[0021] The material storage module 7 is selectively installed in the outer starting area of ​​any set of material conveyors to store one type of material in the workpiece 2 to be processed or the material packaging container 16. The material storage module 7 has a directional feeding function and can be flexibly configured next to the left or right conveyor belt according to production needs.

[0022] The processing module 9 is located on the same side as the material receiving module 7 and at the outer end of the material conveyor belt. It uses the same transmission ratio as the material conveyor belt to process one type of object in the workpiece 2 or the material packaging container 16 that is transported here, thereby realizing operations such as opening the bag, separating or sorting.

[0023] And the bearing positioning module 8 is installed in the same side area between the material storage module 7 and the processing module 9. It is used to smoothly transfer the objects stored in the material storage module 7 to the surface of the material conveyor belt on the corresponding side, so as to complete the accurate positioning and loading of the objects.

[0024] In addition to the content of this application, the processing module 9 in this application further includes: The helical gear transmission assembly is connected to the power source of the material conveyor belt at one end and the power transmission crankshaft 905 is fixedly installed at the other end. The push arm 913 has one end hinged to the power transmission crankshaft 905, and the other end has a folding support arm 909 and a connecting sleeve arm 904 hinged from top to bottom, wherein the connecting sleeve arm 904 is used to limit the adjustment stroke. The other end of the push arm 913 has a workpiece positioning limit block 908 fixed externally.

[0025] At the ends of the folding support arm 909 and the connecting sleeve arm 904 away from the push arm 913, a material handling shovel 911 and a material handling roller 902 with electric telescopic adjustment function are respectively installed. The push arm 913 is driven to reciprocate through the rotation of the power transmission crankshaft 905, which in turn drives the material handling shovel 911 and the material handling roller 902 to perform bag opening or flattening operations. The adjustment function of the material handling shovel 911 and the material handling roller 902 is achieved by installing an electric telescopic hydraulic cylinder 910 on the top of the connecting sleeve arm 904 away from the push arm 913. The material handling shovel 911 and the material handling roller 902 are respectively screwed to the drive end of the electric telescopic hydraulic cylinder 910.

[0026] It should be further explained that in this application, the two material conveyor belts share a power source, which is a power drive motor 5. The input shafts of the two material conveyor belts are fixed to each other. The end of the drive shaft of the power drive motor 5 is synchronously driven by fixing it to the input shaft of one of the material conveyor belts. A motor fixing base 19 is fixed to the bottom of the power drive motor 5. The motor fixing base 19 is fixed to one end of the back of the equipment integrated cabinet 1.

[0027] As a supplement to the content of this application, the helical gear transmission assembly in this application further includes: The equipment stable support base 912 has a shaft-driven helical gear 907 internally hinged. The outer end of the shaft of the shaft-driven helical gear 907 is connected to the outer end of the drive shaft of the power drive motor 5 through a belt drive pulley system 21. The shaft-driven helical gear 903 meshes with the shaft-driven helical gear 907 in a perpendicular state. The shaft of the shaft-driven helical gear 907 is fixed to one end of the power transmission crankshaft 905 to realize the conversion and transmission of power direction.

[0028] It should be added that the bottom of the equipment stable support base 912 is fixed with a workpiece processing bearing platform 901, and the top of the power transmission crankshaft 905 is fixed with a structural reinforcement platform 906. The structural reinforcement platform 906 and the workpiece processing bearing platform 901 are respectively fixed at the top and bottom of the workpiece bearing platform plate 12 where the processing adaptation slot 13 is opened.

[0029] It should be noted that in this application, the belt drive pulley system 21 consists of two drive pulleys and a belt, which is a common transmission component in existing transmission devices. One drive pulley is fixedly mounted on the end of the drive shaft of the power drive motor 5, and the other drive pulley is coaxially fixed to the shaft end of the belt drive helical gear 907. The belt is mounted between the two drive pulleys.

[0030] The material receiving module 7 includes: a material storage frame 704, which is used to store a type of object in the workpiece 2 to be processed or the material packaging container 16. The frame outlet has an inclined structure to facilitate the material to slide naturally onto the top surface of the material conveyor belt. Several damping adjustment paddles 705 are evenly fixed at both ends of the top and bottom of the material storage frame 704 to adjust the falling speed of the material and prevent blockage. It should be noted that the blocking and releasing states of the damping adjustment paddles 705 are achieved based on their own deformation.

[0031] As a supplement to the content of this application, the positioning module 8 in this application further includes: an adjustable support 801, a belt drive wheel system 804 mounted on its middle surface, a servo drive motor 18 mounted on its back to drive the wheel system to rotate, a rotating support 806, one end of which is fixed to one end of the surface of the belt drive wheel system 804, a belt linkage wheel system 810, mounted on the top of the rotating support 806 and connected to the belt drive wheel system 804 through a connecting rod passing through the rotating support 806, an electric adsorption device, mounted on the top end of the belt linkage wheel system 810 away from the connecting rod, used to pick up and transfer materials, and a pneumatic adsorption device, mounted on one side of the surface of the adjustable support 801, which cooperates with the electric adsorption device to complete the opening operation of the material packaging container 16.

[0032] It is worth noting that in this application, both the belt drive pulley system 804 and the belt linkage pulley system 810 are composed of two pulleys and a transmission belt, which is a common type of transmission component in the prior art. Specifically, in this application, the belt drive pulley system 804 includes: a driving pulley, whose central shaft is fixedly connected to the output end of the servo drive motor 18 and rotates synchronously with the motor output shaft to provide power; a driven pulley, which is mounted on the middle surface of the adjusting support 801 via a bearing seat, and is parallel to the driving pulley with a suitable spacing; and a transmission belt, which is sleeved on the outside of the driving pulley and the driven pulley. The belt linkage pulley system 810 includes: a linkage pulley, whose central position is fixedly connected to the top end of the connecting rod passing through the rotating support 806, and rotates synchronously with the connecting rod to transmit power; an auxiliary pulley, which is mounted on the top surface of the rotating support 806 via a bearing seat, and is parallel to the driving pulley with a spacing suitable for the length of the transmission belt; and a linkage belt, which is sleeved on the outside of the linkage pulley and the auxiliary pulley.

[0033] As a supplement to the above, the electric adsorption device in this application includes: a workpiece mounting arm 813, a component assembly shaft 811 inserted in the middle, the bottom of the component assembly shaft 811 being fixed to the top of the corresponding belt linkage wheel system 810, a workpiece positioning sleeve 812 screwed to the top, and two electric adsorption plates 814, which are respectively inserted into the retention grooves opened at both ends of the workpiece mounting arm 813, and the adsorption force is generated by energizing to grab the workpiece.

[0034] It should be further explained that, in this application, the bottom of the screw rod and the central shaft position of the auxiliary wheel in the belt linkage pulley system 810 are fixed by a key connection to ensure that the screw rod rotates synchronously with the auxiliary wheel, thereby driving the workpiece mounting arm 813 and the electric suction plate 814 to complete the angle adjustment. In addition, the screw rod is screwed into the middle of the workpiece mounting arm 813, and the height of the workpiece mounting arm 813 can be adjusted by rotating the screw rod to meet the needs of material packaging containers 16 of different heights.

[0035] It should be further added that, in this application, the pneumatic adsorption device includes: a support arm 807, one end of which is installed on one side of the surface of the adjusting support seat 801; and an assembly frame 809, which is installed on the other end of the support arm 807 by a threaded connection, and contains a plurality of electronic pneumatic adsorption plates 808, with the air lines of each electronic pneumatic adsorption plate 808 neatly arranged on the surface of the assembly frame 809.

[0036] As a supplement to the device proposed in this application, further, in this application, two material conveyor belts are installed inside the equipment integrated cabinet 1, wherein a workpiece bearing platform 12 is fixed on one side of the top of the equipment integrated cabinet 1, and the material storage module 7, the processing module 9 and the bearing positioning module 8 are all integrated and installed on the workpiece bearing platform 12, wherein a number of structural support reinforcement seats 20 for reinforcement are fixed between the back of the workpiece bearing platform 12 and the back of the equipment integrated cabinet 1.

[0037] Specifically, a sliding guide rail 701 and a position adjustment guide rail 803 are fixed at one end and the middle of the surface of the workpiece bearing platform 12, respectively. A screw structure, namely two screw seats, is installed in the middle of the position adjustment guide rail 803. The screw seats are fixed at the beginning and end of the position adjustment guide rail 803 in the middle of the workpiece bearing platform 12. A transmission screw 805 is screwed between the two screw seats. The adjustment bearing seat 801 is slidably connected to the position adjustment guide rail 803 and screwed to the transmission screw 805. A manual adjustment handle 815 is fixed to the top of the transmission screw 805. The sliding guide rail 701 is fixed to one end of the surface of the workpiece bearing platform 12, and is externally slidably connected to the movable bearing seat 706. An extension bracket 703 is fixed to the outside of the movable bearing seat 706. One side of the bottom of the material storage frame 704 is fixed to one end of the top of the extension bracket 703. A structural reinforcement arm 702 is fixed between the other side of the material storage frame 704 and the other end of the top of the extension bracket 703.

[0038] It should be further explained that, in this technical solution, a magnetic sleeve 707 is installed at one end of the movable support 706, and a positioning and engaging slot 802 is opened at the bottom of one end of the adjustable support 801. A magnetic connecting arm 10 is installed between the positioning and engaging slot 802 and the magnetic sleeve 707.

[0039] It should also be noted that the workpiece bearing platform 12 has processing adaptation slots 13 and transmission linkage slots 11 respectively at the positions corresponding to the processing module 9 and the bearing positioning module 8. The top of the equipment integrated cabinet 1 is equipped with a human-machine interface control panel 3 for setting parameters, starting and stopping control and status monitoring. The human-machine interface control panel 3 is electrically connected to the servo drive motor 18, the power drive motor 5, the electric telescopic hydraulic cylinder 910, the electric suction plate 814 and the electronic pneumatic suction plate 808. In addition, the top of the equipment integrated cabinet 1 is also provided with a conveyor belt adaptation slot 14 that matches the two material conveyor belts, so that the working surface of the conveyor belt is flush with the surface of the cabinet, which facilitates the continuous flow of materials. One end of one of the conveyor belt adaptation slots 14 also extends to a storage adaptation slot 4. It should be added that the two material conveyor belts are a secondary material conveyor belt 6 and a primary material conveyor belt 15. The workpiece bearing platform 12 is fixed with a material separation baffle 17 between the secondary material conveyor belt 6 and the primary material conveyor belt 15.

[0040] Finally, it should be added that the storage and feeding logic of this device is as follows: the material receiving module 7 is slidably connected to the sliding guide rail 701 through the movable bearing seat 706, and can be flexibly configured next to any left or right conveyor belt according to production needs. The material storage frame 704 is used to store the workpiece 2 to be processed or the material packaging container 16. The frame outlet adopts an inclined structure design, so that the material can slide naturally onto the surface of the conveyor belt by its own gravity. The top and bottom ends of the material storage frame 704 are evenly fixed with damping adjustment paddles 705. The paddles can block and release the material through their own deformation, thereby adjusting the falling speed of the material and effectively avoiding material blockage. The structural reinforcement arm 702 is used to strengthen the connection strength between the material storage frame 704 and the placement extension bracket 703 to prevent the frame from shaking during the feeding process.

[0041] The logic for the transfer and unpacking of the bearing positioning module 8 is as follows: the operator rotates the manual adjustment handle 815 to drive the transmission screw 805 to rotate, so that the adjustment bearing seat 801 slides along the position adjustment guide rail 803, thereby calibrating the horizontal position of the bearing positioning module 8. The magnetic sleeve 707 and the positioning slot 802 are magnetically connected to the support arm 10 for fixation, ensuring the positional accuracy between modules.

[0042] The material transfer process is as follows: After the servo drive motor 18 starts, it drives the drive wheel of the belt drive pulley system 804 to rotate, which in turn drives the driven wheel to rotate via the drive belt. This causes the rotating support 806 to move horizontally to the discharge port of the material receiving module 7. The belt drive pulley system 804 drives the linkage wheel of the belt linkage pulley system 810 to rotate via the connecting rod. The linkage belt drives the auxiliary wheel to rotate, causing the workpiece mounting arm 813 of the electric suction device to rotate to a specified angle. At the same time, the height of the arm is adjusted by rotating the screw rod to adapt to the height requirements of the material packaging container 16. When the auxiliary plate 814 is energized, it generates an adsorption force to grab the material in the material storage frame 704. Then, the belt drive wheel system 804 drives the rotating support 806 to move above the corresponding conveyor belt. When the power is cut off, the material is released to complete the positioning. Container opening operation: When it is necessary to open the material packaging container 16, the electronic pneumatic adsorption plate 808 of the pneumatic adsorption device starts the adsorption box cover, and at the same time, the electric adsorption device grabs the box body. The two move in opposite directions to complete the opening operation. The air pipeline of the electronic pneumatic adsorption plate 808 is neatly arranged on the surface of the assembly frame 809 to ensure the stability of the air path.

[0043] Furthermore, in this technical solution, the power drive motor 5 transmits power to the belt drive helical gear 907 through the belt drive pulley system 21. The belt drive helical gear 907 rotates within the equipment stable support base 912 and is linked with the vertically meshing belt drive helical gear 903 to convert the horizontal power into the vertical power, driving the power transmission crankshaft 905 to rotate. The structural reinforcement platform 906 and the workpiece processing bearing platform 901 are respectively fixed to the top and bottom of the processing adapter slot 13 on the back of the workpiece bearing platform 12 to ensure the stability of the crankshaft operation.

[0044] It should also be noted that when the bag opening and cutting operation is performed, when the workpiece 2 to be processed (BFS continuous plate medicine bottle packaging bag) is transported to the processing area, the power transmission crankshaft 905 drives the push arm 913 to reciprocate, the folding support arm 909 drives the material handling shovel 911 to approach the material bag, the electric telescopic hydraulic cylinder 910 controls the shovel to extend, and the bag is precisely cut open by using the blade part, and then the shovel retracts and resets.

[0045] When the material is being pushed: When the processed plate-shaped medicine bottles need to be pushed to the material packaging container 16, the electric telescopic hydraulic cylinder 910 controls the material handling shovel 911 to remain extended, and the reciprocating motion of the push arm 913 directly drives the material handling shovel 911 to move forward, smoothly pushing the material to the designated position, thus realizing the directional transfer of the material.

[0046] It should be further added that this technical solution has the functions of horizontal extrusion and pushing (for the workpiece 2 to be processed) and vertical impact opening of the packaging container (in conjunction with the material packaging container 16). Horizontal extrusion and pushing: When processing the connecting plate medicine bottle inside the workpiece 2, the material processing roller 902 is in a horizontal position. The push arm 913 drives the connecting sleeve arm 904 to move. The roller surface contacts the items inside the workpiece. Through the extrusion (rolling) action, the items are pushed to move in a direction inside the workpiece to complete the sorting or placement of the materials. The workpiece positioning limit block 908 is used to limit the adjustment stroke of the connecting sleeve arm 904 to avoid excessive movement of the parts.

[0047] Vertical impact to open the packaging container: When it is necessary to load materials into the material packaging container 16, the material handling roller 902 switches to a vertical setting, and the push arm 913 drives the roller to move forward. The end of the roller directly impacts the opening of the material packaging container 16, opening the container opening and keeping it open. At this time, the material handling shovel 911 pushes the material forward in sync to complete the bagging operation.

[0048] It should be noted that after the workpiece 2 to be processed is conveyed to the processing area by the primary material conveyor belt 15, the material handling shovel 911 first completes the bag opening and cutting, and then the material handling roller 902 runs horizontally, squeezing and pushing the contents of the workpiece to be sorted and placed; then the material handling roller 902 switches to vertical, knocking open the opening of the material packaging container 16 on the secondary material conveyor belt 6, and finally the material handling shovel 911 pushes the sorted material into the container. It should be pointed out that the above different operating states and processes require the device proposed in this application to be repeatedly operated, and the direction of the material handling roller 902, as well as the collection and processing of the processed materials, need to be manually adjusted in order to achieve this.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
