Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pharmaceutical packaging equipment, and specifically relates to an active independent waste rejection device for blister packaging aluminum-plastic machines and the blister packaging aluminum-plastic machine itself. Background Technology
[0002] Blister packaging is a typical form of packaging for solid dosage forms. It is a small-dose blister pack suitable for patients, offering advantages such as light weight, easy portability, good sealing, prevention of drug mixing, and no waste during administration. It has become the mainstream packaging method for solid dosage forms in my country and is widely used in the pharmaceutical field. The equipment used for blister packaging is called a blister packaging machine, and because the materials used are mostly plastic film and aluminum foil, it is also known as a blister aluminum-plastic packaging machine.
[0003] In a blister pack aluminum-plastic composite machine, polyvinyl chloride (PVC) is formed into grooves of a specific shape by a molding plate. After the tablets are filled inside, a layer of aluminum foil (or other material) is applied to the surface to create a sealed environment. Visual inspection confirms that the blister pack meets requirements, and then a punching device cuts it into individual aluminum-plastic composite sheets. A rejection device, located behind the punching device, rejects individual aluminum-plastic composite sheets based on rejection signals issued by the operator or visual inspection results.
[0004] However, in existing aluminum-plastic composite (APC) machines, tablets and packaging materials form a whole in multiple channels during operation, eventually forming a single APC at the punching position. In actual production, operators need to actively reject defective APCs every time, checking whether the batch number, appearance, and other information of the tablets meet the quality standards. However, the existing rejection devices cannot distinguish which channel the rejected APCs belong to, thus making it impossible to identify the source of the problematic APCs and the specific location of the problem, resulting in wasted time and packaging materials. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide an active independent rejection device for blister aluminum-plastic machines and a blister aluminum-plastic machine, which aims to solve the problem that the rejection devices in the prior art cannot determine the specific source of the rejected aluminum-plastic sheets, thus requiring time to determine the source of the problem, resulting in wasted time and packaging materials.
[0006] The present invention proposes an active independent rejection device for a blister packaging aluminum-plastic machine, comprising multiple main boards, multiple conveying components respectively disposed below the main boards, and multiple rejection components respectively disposed on each of the conveying components. Each conveying component includes a fixed plate, a conveyor belt disposed on the fixed plate, and an adsorption component disposed on the conveyor belt. Each rejection component includes a base disposed on one side of the conveyor belt, a rejection plate rotatably connected to the base, and a driving component facing the rejection plate. The base and the driving component are disposed on the fixed plate, and the driving component is used to drive the rejection plate to rotate and tilt.
[0007] The aforementioned active independent rejection device for blister pack aluminum-plastic packaging machines utilizes multiple conveying components. Each component transports blister packs cut to their corresponding channel. Rejection components on each conveying component, through manual observation or image recognition, determine the real-time location of defective blister packs. Based on the location of the defective blister packs, the corresponding rejection component is controlled to reject them, and the rejected blister packs are collected. This identifies the source of the defective blister packs, allowing for individual processing and problem identification and resolution. This significantly reduces processing time and prevents continuous production of defective blister packs, thus avoiding packaging material waste. In specific implementation, the blister packs are attracted by suction elements on the conveyor belt, causing them to float and be conveyed. After the defective blister pack's location is determined, a drive unit controls the rejection plate to rotate, causing the defective blister pack to move along the inclined rejection plate. The weight of the defective blister pack exceeds the suction force of the suction elements, causing the defective blister pack to fall, thus achieving the rejection function. Therefore, this utility model solves the problem that the existing rejection devices cannot determine the specific source of the rejected aluminum composite panels, thus requiring time to determine the source of the problem, resulting in wasted time and packaging materials.

The middle portion of the longitudinal plate portion is rotatably connected to the base, and the two transverse plate portions are perpendicularly connected to the longitudinal plate portion and are respectively located outside the two conveyor belts.
[0011] Preferably, a vertical plate is provided on the side of the horizontal plate portion away from the vertical plate portion, the vertical plate portion is perpendicular to the horizontal plate portion and the vertical plate portion, and the height of the vertical plate portion on the side away from the conveyor belt is greater than a preset value.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0030] Please see Figures 1 to 5 The image shows an active independent rejection device for a blister aluminum-plastic machine according to an embodiment of the present invention. It includes multiple main boards 10, multiple conveying components 20 respectively disposed below the main boards 10, and multiple rejection components 30 respectively disposed on each conveying component 20. The conveying component 20 includes a fixed plate 21, a conveyor belt 22 disposed on the fixed plate 21, and an adsorption component 23 disposed on the conveyor belt 22. The rejection component 30 includes a base 31 disposed on one side of the conveyor belt 22, a rejection plate 32 rotatably connected to the base 31, and a driving component 33 facing the rejection plate 32. The base 31 and the driving component 33 are disposed on the fixed plate 21, and the driving component 33 is used to drive the rejection plate 32 to rotate and tilt.
[0031] Understandably, by setting up multiple conveying components 20, each conveying component 20 can transport the cut blister packs of medicine to its corresponding channel. Then, through the rejection components 30 on each conveying component 20, the real-time position of defective blister packs on each conveying component 20 can be determined by manual observation or image recognition. Based on the real-time position of the defective blister packs, the corresponding rejection component 30 is controlled to reject them, and the rejected blister packs are collected. This helps to determine the source of the defective blister packs, allowing for individual processing of the corresponding source. This process greatly reduces problem-solving time and, due to timely processing, avoids the continuous production of defective blister packs, thus preventing packaging material waste. In practical implementation, the medicine blister pack is adsorbed by the adsorption element 23 on the conveyor belt 22 in the conveying assembly 20, causing the medicine blister pack to be suspended and conveyed along the conveyor belt 22. After determining the position of the defective medicine blister pack, the drive element 33 controls the rotation of the rejection plate 32, causing the defective medicine blister pack to move along the inclined rejection plate 32. This causes the weight of the defective medicine blister pack to exceed the adsorption force of the adsorption element 23, causing the defective medicine blister pack to fall, thus achieving the rejection function. Therefore, this utility model solves the problem in the prior art where rejection devices cannot determine the specific source of the rejected aluminum-plastic composite blister pack, thus requiring time to determine the source of the problem, resulting in wasted time and packaging materials. Furthermore, in practical implementation, the drive element 33 can be any device that can be remotely controlled to drive the rejection plate 32 to rotate and reset, such as an electric push rod or a hydraulic rod.
[0032] Specifically, the fixed plate 21 has two parallel conveyor belts 22 on both sides, and the base 31 is fixed between the two conveyor belts 22. Each of the two conveyor belts 22 is connected to a pulley 24, and the two pulleys 24 are mounted on the same rotating shaft 25. The two parallel conveyor belts 22 thus adhere and fix the sides of the medicine plate, thereby constraining both ends and ensuring the medicine plate moves stably in a preset posture. This avoids the situation where a single conveyor belt 22 adheres to the middle of the medicine plate, causing the medicine plate to rotate and change posture during transport, affecting subsequent processing. Furthermore, the narrower conveyor belts 22 on both sides ensure that the medicine plate is fixed at both ends while providing sufficient space in the middle of the fixed plate 21 for fixing the base 31.
[0033] Additionally, the rejection plate 32 includes a longitudinal plate portion 321 and transverse plate portions 322 disposed at both ends of the longitudinal plate portion 321. The middle part of the longitudinal plate portion 321 is rotatably connected to the base 31, and the two transverse plate portions 322 are perpendicularly connected to the longitudinal plate portion 321 and are respectively located on the outer sides of the two conveyor belts 22. In specific implementation, by setting a relatively long longitudinal plate portion 321 and transverse plate portions 322 disposed at both ends of the longitudinal plate portion 321, when rejecting defective medicine plates by the rejection plate 32, the rejection plate 32 can take into account the entire medicine plate, so that the longitudinal plate portion 321 and the transverse plate portions 322 respectively contact the outer contour of the medicine plate. Thus, through multi-point contact, the movement direction of the defective medicine plate is stably guided, so that the defective medicine plate falls into the preset area, avoiding the reaction force of local contact being located in a local area, which would cause the falling direction of the defective medicine plate to be unstable.
[0034] Furthermore, a vertical plate portion 323 is provided on the side of the horizontal plate portion 322 away from the vertical plate portion 321. The vertical plate portion 323 is perpendicular to both the horizontal plate portion 322 and the vertical plate portion 321, and the height of the side of the vertical plate portion 323 away from the conveyor belt 22 is greater than a preset value. In specific implementation, by setting the vertical plate portion 323, the defective medicine plate moving along the rejection plate 32 is obstructed, causing the defective medicine plate to fall into the preset area, thus avoiding instability in the falling area of the defective medicine plate. Typically, the height of the side of the vertical plate portion 323 away from the conveyor belt 22 is greater than the height of the defective medicine plate to ensure the obstructive effect of the vertical plate portion 323.
[0035] Specifically, a waste collection box 40 is provided below the rejection assembly 30. The waste collection box 40 includes a box body 41 with an opening at the top and an inclined plate 42 disposed at the opening. The height of the inclined plate 42 gradually increases from one end to the other in the forward direction of the conveyor belt 22. In practice, by setting up the waste collection box 40 to collect the defective medicine plates rejected by the rejection assembly 30, and by observing the condition of the defective medicine plates in the waste collection box 40, the source of the problem corresponding to the defective medicine plates can be determined. This enables rapid problem resolution, saving time and packaging materials. In addition, the inclined plate 42 guides the falling defective medicine plates to avoid collisions and stacking blockages.
[0036] Additionally, the box body 41 is equipped with a drawer 43, and one side of the box body 41 has a clearance groove 411 adapted to the drawer 43. The drawer 43 has a handle 44 on the side away from the box body 41. In practice, the drawer 43 is pulled out of the box body 41 using the handle 44 to determine the condition of the defective medicine plates in the defective waste collection box 40. The handle 44 and drawer 43 facilitate the confirmation and removal of defective medicine plates by staff. It should be noted that due to potential errors in manual control or algorithmic control after image recognition, a secondary inspection of the defective medicine plates in the box body 41 after removal is necessary to ensure accuracy and condition. Furthermore, in practice, a sampling inspection function is also implemented using the removal component 30. Therefore, it is necessary to easily remove the medicine plates from the box body 41 and to install an inclined plate 42 to prevent the medicine plates from colliding with each other and affecting the accuracy of subsequent observations.
[0037] Specifically, multiple waste rejection components 30 are staggered, and multiple waste collection boxes 40 are located directly below their respective waste rejection components 30. In practice, by staggering the multiple waste rejection components 30, mutual interference between them is avoided, and the spacing between each conveyor belt 22 can be made smaller, while the waste rejection components 30 do not interfere with each other, thereby reducing the overall size of the waste rejection device.
[0038] Additionally, the active independent waste rejection device also includes a housing 50, within which multiple main boards 10 are equidistantly distributed. The main boards 10 and the housing 50 are fixedly connected by multiple positioning shafts 60. In practice, the housing 50 protects the internal components from dust and external impacts. Furthermore, parts of the housing 50 are made of transparent material to allow personnel to observe the internal waste transfer and rejection process.
[0039] Specifically, an extension portion 11 extends downward from one side of the motherboard 10, and the side and top of the fixing plate 21 are connected to the extension portion 11 and the bottom of the motherboard 10, respectively. In addition, by providing the extension portion 11, the fixing contact area between the fixing plate 21 and the motherboard 10 is increased, so that the fixing plate 21 is more firmly fixed to the motherboard 10.
[0040] It should be noted that in some optional embodiments, the housing 50 has clearance grooves at both ends to allow an external feeding device to transfer the medicine blister pack onto the conveyor belt 22. The specific feeding device can be any device or structure capable of transferring the medicine blister pack, such as a mechanical gripper or mechanical suction cup. Furthermore, a drive device can be installed on the outside of the housing 50, with its drive shaft passing through the housing 50 and connected to the pulley 24, thereby driving the pulley 24 to move and achieve the conveying function. Additionally, in some optional embodiments, the adsorption element 23 can be an existing component capable of adsorption, or an annular air duct can be provided on both sides of the conveyor belt 22, with adsorption holes on the conveyor belt 22 communicating with the annular air duct, allowing the material to be adsorbed through the adsorption holes by the adsorption force of the annular air duct.
[0041] In summary, the active independent rejection device for blister pack aluminum-plastic machine described in the above embodiments of this utility model, by setting up multiple conveying components 20, allows each conveying component 20 to convey the cut blister packs in its corresponding channel. Then, through the rejection components 30 on each conveying component 20, and with manual observation or image recognition assistance, the real-time position of defective blister packs on each conveying component 20 is determined. Based on the real-time position of the defective blister packs, the corresponding rejection component 30 is controlled to reject them, and the rejected blister packs are collected. This identifies the source of the defective blister packs, allowing for individual processing of the corresponding source, thus identifying the problem and implementing solutions or adjustments. This significantly reduces problem-solving time and, due to timely processing, avoids the continuous production of defective blister packs, preventing packaging material waste. In practical implementation, the medicine blister pack is adsorbed by the adsorption element 23 on the conveyor belt 22 in the conveying assembly 20, causing the medicine blister pack to be suspended and conveyed along the conveyor belt 22. After determining the position of the defective medicine blister pack, the drive element 33 controls the rotation of the rejection plate 32, causing the defective medicine blister pack to move along the inclined rejection plate 32. This makes the weight of the defective medicine blister pack greater than the adsorption force of the adsorption element 23 on the defective medicine blister pack, causing the defective medicine blister pack to fall, thereby achieving the rejection function. Therefore, this utility model solves the problem in the prior art that rejection devices cannot determine the specific source of the rejected aluminum-plastic composite blister pack, thus requiring time to determine the source of the problem, resulting in wasted time and packaging materials.
[0042] Furthermore, this utility model also proposes a blister pack aluminum-plastic machine, including a PVC rigid sheet conveying device, a heating component blister forming device, a filling device, a heat sealing device, a punching device, and the active independent rejection device for the blister pack aluminum-plastic machine mentioned in the above embodiments. In specific implementation, the PVC rigid sheet conveying device transports the PVC, the heating component blister forming device heats and softens the PVC to form it, the filling device fills the formed blister with medicine, the heat sealing device seals the aluminum foil and the blister, the sealed blister pack is then punched to obtain a medicine blister of a preset size, and finally the active independent rejection device identifies and rejects defects in the punched medicine blister, thus completing the entire process of the blister pack aluminum-plastic machine.
