Abstract
Description
Technical Field
[0001] This utility model relates to the field of medicine bottle detection technology, specifically a device for rejecting irregularly shaped bottles. Background Technology
[0002] After the packaging containers pass through the testing equipment, qualified and unqualified products need to be separated. Standard round bottles (such as ampoules, oral liquids, and vials) are usually separated by an auger (also known as a screw) and then sent into different channels by a swing mechanism; or they are vacuumed away by a bottle-out wheel and sent into different channels.
[0003] Chinese utility model patent with authorization announcement number CN211515254U discloses a bottle-breaking and waste-removing device, including a track and a guardrail set above the track. The output end of the track is provided with a swing block that can rotate and swing in a horizontal plane. The lower end of the swing block is connected to a rotary shaft. The swing block is composed of a base plate and a partition plate located on the base plate. The gap between two adjacent partition plates forms a guide groove.
[0004] In existing technologies, the oscillating blocks all contact the packaging container through their side planes. For standard-shaped round bottles (such as ampoules, oral liquids, and vials), the oscillating blocks can make good contact with the packaging container. However, for some specially shaped packaging containers, such as... Figure 1 The flat, irregularly shaped bottle shown has a large contact area with the conveyor belt, and its side is inclined to the horizontal plane. When the side of the swing block contacts it and pushes it to move on the conveyor belt, the large friction and small contact area with the swing block make it very easy for the irregularly shaped bottle to break, resulting in product loss.
[0005] Based on this, this utility model designs a waste removal device for irregularly shaped bottles to solve the above problems. Utility Model Content
[0006] This invention provides a waste rejection device for irregularly shaped bottles, which solves the technical problem that the contact area between the swing block and the irregularly shaped bottle in the prior art is too small.
[0007] According to one aspect of the present invention, a device for rejecting irregularly shaped bottles is provided, comprising a conveyor belt and a bottle-separating unit. The conveyor belt is used to carry irregularly shaped bottles and drive them to move along a set direction. The conveyor belt is provided with multiple bottle outlet channels. The bottle-separating unit includes a bottle-separating block and a driving assembly. The bottle-separating block is rotatably disposed at the bottle inlet end of the bottle outlet channel. The driving assembly is used to drive the bottle-separating block to rotate and swing to guide the irregularly shaped bottles into different bottle outlet channels. The side of the bottle-separating block that contacts the irregularly shaped bottle has a contour groove extending along its guiding direction. The contour groove matches the shape and size of the irregularly shaped bottle to increase the contact area between the bottle-separating block and the irregularly shaped bottle.
[0008] As a further embodiment of this utility model, the driving component is connected to the end of the bottle-splitting block away from the bottle outlet channel, so that the driving force of the driving component for driving the bottle-splitting block to rotate and swing is applied to the end of the bottle-splitting block away from the bottle outlet channel.
[0009] As a further embodiment of this utility model, the driving assembly includes a drive motor, a gear, and an arc rack. The gear is fixedly connected to the output shaft of the drive motor, and the arc rack is fixedly connected to the bottle dividing block. The gear and the arc rack mesh with each other.
[0010] As a further embodiment of this invention, the radius of the gear is smaller than the radius of the circular arc rack.
[0011] As a further embodiment of this utility model, the conveyor belt is provided with three baffles, which are arranged side by side to form two bottle outlet channels. The bottle separating block is rotatably mounted on the baffle located in the middle, and the arc rack is fixed on the top of the bottle separating block. The rotation axis of the bottle separating block and the baffle is coincident with the center of the arc rack.
[0012] As a further embodiment of this utility model, the conveyor belt is provided with multiple baffles, which are arranged side by side and form a bottle outlet channel through adjacent two baffles. Multiple bottle separating blocks are provided, and the multiple bottle separating blocks are connected to the multiple baffles one by one to form multiple bottle separating channels. The multiple bottle separating channels are connected to the multiple bottle outlet channels one by one. The bottle separating block includes a rotating end that rotates with the baffle and a sliding end that slides with the rotating end. The sliding end is slidably disposed at the end of the rotating end away from the baffle along the length direction of the rotating end. The arc rack is fixedly connected to one of the multiple sliding ends and movably connected to the other sliding ends.
[0013] As a further embodiment of this utility model, the rotation center of the sliding end fixedly connected to the arc rack coincides with the center of the arc rack, and the sliding end movably connected to the arc rack slides and engages with the arc rack along its own sliding direction and the sliding direction of the rotating end.
[0014] As a further embodiment of this utility model, a preset gap is left between the bottom end of the bottle dividing block and the top surface of the conveyor belt.
[0015] As a further embodiment of this utility model, the irregular bottle rejection assembly also includes a guide channel, which is located above the conveyor belt. The guide channel is used to guide the movement path of the irregular bottle and correct the angle of the irregular bottle. The bottle outlet end of the guide channel is adjacent to the bottle separating block.
[0016] As a further embodiment of this utility model, a detection component is provided on the side of the guide channel, which is used to detect whether the irregularly shaped bottle is in place.
[0017] This utility model has the following beneficial effects:
[0018] This device features a contour groove on the side of the bottle-separating block that contacts irregularly shaped bottles. This groove matches the shape and size of the irregularly shaped bottle. When the bottle-separating block moves the bottle, it contacts the bottle through the contour groove, increasing the contact area. This distributes the driving force of the bottle across a larger surface area, reducing the stress per unit area on the bottle, lowering the probability of breakage, and ensuring safety when the bottle-separating block moves the bottle on the conveyor belt. Furthermore, the contour groove guides the bottle-separating block through the bottle-separating block, ensuring continuous contact throughout the entire guiding process, maintaining a large contact area between the bottle-separating block and the bottle.
[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.
[0030] Please see Figure 1-6 This utility model provides a technical solution: including a conveyor belt 1 and a bottle-splitting unit. The conveyor belt 1 is used to carry irregularly shaped bottles and drive the irregularly shaped bottles to move along a set direction. The conveyor belt 1 is provided with multiple bottle outlet channels. The bottle-splitting unit includes a bottle-splitting block 3 and a driving component. The bottle-splitting block 3 is rotatably set at the bottle inlet end of the bottle outlet channel. The driving component is used to drive the bottle-splitting block 3 to rotate and swing to guide the irregularly shaped bottles into different bottle outlet channels. The side of the bottle-splitting block 3 that contacts the irregularly shaped bottle is provided with a contour groove 31 extending along its guiding direction. The contour groove 31 matches the shape and size of the irregularly shaped bottle to increase the contact area between the bottle-splitting block 3 and the irregularly shaped bottle.
[0031] During operation, irregularly shaped bottles are conveyed onto conveyor belt 1. Driven by conveyor belt 1, the irregularly shaped bottles move along a set direction. When the irregularly shaped bottles move to a specific position along the set direction, they will first contact the bottle separating block 3. The bottle separating block 3 can rotate and swing under the drive of the drive component, thereby forming different angles and guiding the irregularly shaped bottles in different directions, thus guiding the irregularly shaped bottles into different bottle outlet channels, so as to move qualified and unqualified irregularly shaped bottles along different paths, thereby realizing the classification of qualified and unqualified products.
[0032] like Figure 4 As shown, the bottle separating block 3 has a contour groove 31 on its side for contacting irregularly shaped bottles. After the irregularly shaped bottle contacts the separating block 3, the separating block 3 may need to rotate and swing to change the guiding direction of the irregularly shaped bottle into different separating channels. During this process, the separating block 3 will push the irregularly shaped bottle to move on the conveyor belt 1. When the separating block 3 pushes the irregularly shaped bottle to move, its driving force on the irregularly shaped bottle is applied to the irregularly shaped bottle by its contact surface with the irregularly shaped bottle. The contour groove 31 matches the shape and size of the irregularly shaped bottle. When the separating block 3 pushes the irregularly shaped bottle to move, it will pass through the contour groove 31. By contacting the irregularly shaped bottle, the contact area with the irregularly shaped bottle is increased. This allows the driving force that moves the irregularly shaped bottle to be evenly distributed over a larger area of the bottle's surface, reducing the force per unit area on the bottle and lowering the probability of breakage. This ensures the safety of the bottle divider block 3 when it pushes the irregularly shaped bottle on the conveyor belt 1. At the same time, the contour groove 31 guides the irregularly shaped bottle through the bottle divider block 3. Throughout the entire guiding process of the bottle divider block 3, it can contact the irregularly shaped bottle through the contour groove 31, ensuring that the bottle divider block 3 and the irregularly shaped bottle always maintain a large contact area.
[0033] Specifically, the rotating and swinging plane of the bottle-separating block 3 is parallel to the top surface of the conveyor belt 1. When the conveyor belt 1 moves the irregularly shaped bottle, regardless of the movement path of the irregularly shaped bottle, it always moves in the plane formed by the top surface of the conveyor belt 1. The fact that the rotating and swinging plane of the bottle-separating block 3 is parallel to the top surface of the conveyor belt 1 ensures that the distance between the bottle-separating block 3 and the top surface of the conveyor belt 1 remains unchanged during the rotation and swinging process. This ensures that the distance between the contour groove 31 and the top surface of the conveyor belt 1 remains unchanged, ensuring that the irregularly shaped bottle can smoothly enter the contour groove 31 and will not get stuck during the rotation and swinging process of the bottle-separating block 3.
[0034] Furthermore, the drive assembly is connected to the end of the bottle-splitting block 3 away from the bottle outlet channel, so that the driving force of the drive assembly for driving the bottle-splitting block 3 to rotate and swing is applied to the end of the bottle-splitting block 3 away from the bottle outlet channel.
[0035] like Figure 6 As shown, the bottle separator 3 is rotatably positioned at the inlet end of the bottle outlet channel. This means that when the bottle separator 3 is driven to rotate and swing, its rotation axis is located at the end of the bottle separator 3 closest to the bottle outlet channel, while the connection point between the drive component and the bottle separator 3 is at the end of the bottle separator 3 furthest from the bottle outlet channel. This means that when the bottle separator 3 is driven to rotate and swing, the driving force applied by the drive component acts on the end of the bottle separator 3 furthest from the bottle outlet channel, away from the rotation axis of the bottle separator 3. This adds a constraint to the weakest free end of the bottle separator 3 structure, improving the overall stability of the bottle separator 3 structure and reducing the shaking of the bottle separator 3 during rotation and swing. Furthermore, connecting the drive component to the end of the bottle separator 3 furthest from the bottle outlet channel reduces the impact of the drive component's vibration and changes in the magnitude of the driving force on the bottle separator 3, further enhancing the stability of the bottle separator 3 during rotation and swing. When the bottle separator 3 rotates and swings to push the irregularly shaped bottle to change its movement path, the stability of the force applied by the bottle separator 3 to the irregularly shaped bottle is ensured, reducing the probability of breakage of the irregularly shaped bottle.
[0036] Specifically, the drive assembly includes a drive motor 41, a gear 42, and an arc rack 43. The gear 42 is fixedly connected to the output shaft of the drive motor 41, and the arc rack 43 is fixedly connected to the bottle dividing block 3. The gear 42 and the arc rack 43 mesh with each other.
[0037] like Figure 2 As shown, an arc rack 43 is provided at the end of the bottle-splitting block 3 away from the baffle 2. The drive motor 41 meshes with the arc rack 43 through the gear 42. When the bottle-splitting block 3 needs to swing, the drive motor 41 drives the gear 42 to rotate. The gear 42 drives the arc rack 43 and the bottle-splitting block 3 connected to the arc rack 43 to rotate, thereby driving the bottle-splitting block 3 to rotate and swing. This realizes that the drive component drives the bottle-splitting block 3 to rotate and swing from the end of the bottle-splitting block 3 away from the baffle 2.
[0038] Preferably, the radius of gear 42 is smaller than the radius of arc of the circular arc rack 43, which reduces the transmission ratio between gear 42 and circular arc rack 43, reduces the impact of drive motor 41 jump and changes in driving force on circular arc rack 43, and further increases the stability of bottle-splitting block 3 during rotation and oscillation.
[0039] Figure 2 The first example of a bottle-separating unit is disclosed. In this example, the conveyor belt 1 is provided with three baffles 2, which are arranged side by side to form two bottle outlet channels. The bottle-separating block 3 is rotatably mounted on the baffle 2 located in the middle. The arc rack 43 is fixed to the top of the bottle-separating block 3, and the rotation axis of the bottle-separating block 3 and the baffle 2 is coincident with the center of the arc rack 43.
[0040] like Figure 2 As shown, three baffles 2 are arranged side by side, forming a bottle outlet channel between two adjacent baffles 2. The three baffles 2 form two bottle outlet channels, which are used to separate qualified and unqualified products, thereby achieving the separation of qualified and unqualified products. The bottle separating block 3 is rotatably set at the bottle inlet end of the middle baffle 2. The rotating and swinging of the bottle separating block 3 guides the irregularly shaped bottles into different bottle outlet channels, thereby achieving the separation of qualified and unqualified products. In this example, the arc rack 43 is fixedly set at the top of the bottle separating block 3, and the arc center of the arc rack 43 coincides with the rotation axis of the bottle separating block 3. When the gear 42 rotates and drives the arc rack 43 and the bottle separating block 3 to rotate, the rotation axis of the arc rack 43 and the bottle separating block 3 coincides. The bottle separating block 3 will not get stuck during rotation. The overall device has a simple structure and is easy to use.
[0041] Figure 3 A second example of a bottle-separating unit is disclosed. In this example, multiple baffles 2 are provided on the conveyor belt 1. The multiple baffles 2 are arranged side by side and form a bottle outlet channel through two adjacent baffles 2. Multiple bottle-separating blocks 3 are provided. The multiple bottle-separating blocks 3 are connected one-to-one with the multiple baffles 2 to form multiple bottle-separating channels. The multiple bottle-separating channels are connected one-to-one with the multiple bottle outlet channels. The bottle-separating block 3 includes a rotating end 32 that rotates with the baffle 2 and a sliding end 33 that slides with the rotating end 32. The sliding end 33 is slidably disposed at the end of the rotating end 32 away from the baffle 2 along the length direction of the rotating end 32. The arc rack 43 is fixedly connected to one of the multiple sliding ends 33 and movably connected to the other sliding ends 33.
[0042] like Figure 3As shown, in this example, the number of bottle-separating blocks 3 is the same as the number of baffles 2. Each baffle 2 has a bottle-separating block 3 rotatably mounted at its inlet end. Adjacent bottle-separating blocks 3 form a bottle-separating channel. Since the number of bottle-separating blocks 3 is the same as the number of baffles 2, the number of bottle-separating channels formed by multiple bottle-separating blocks 3 is the same as the number of bottle-out channels, and the bottle-separating channels and bottle-out channels correspond one-to-one. Since the bottle-separating channel is formed by two bottle-separating blocks 3, it can guide the irregularly shaped bottle from both sides. When guiding the irregularly shaped bottle into the bottle-out channel through the bottle-separating channel, the two bottle-separating channels do not affect each other. When guiding the irregularly shaped bottle into the bottle-out channel through the bottle-separating block 3, there is no need to wait for the previous irregularly shaped bottle to enter the bottle-out channel. Even if the previous irregularly shaped bottle is still in the bottle-separating channel, the next irregularly shaped bottle can still enter the same bottle-separating channel or another bottle-separating channel, which can improve the bottle-separating efficiency of the bottle-separating unit, thereby improving the overall efficiency of the irregularly shaped bottle rejection component.
[0043] Because the rotational axes of different bottle-splitting blocks 3 are different, when all bottle-splitting blocks 3 are driven to rotate and swing by the arc rack 43, they may get stuck due to different rotational and swinging trajectories. Therefore, the bottle-splitting blocks 3 are divided into a rotating end 32 and a sliding end 33. The rotating end 32 is rotatably connected to the baffle 2, while the sliding end 33 is slidably disposed on the rotating end 32 along the length direction of the rotating end 32. The arc rack 43 is fixedly connected to one of the sliding ends 33 and movably connected to the remaining sliding ends 33. When the bottle-splitting blocks 3 are driven to rotate and swing by the arc rack 43, the sliding end 33 can move along its sliding direction, thereby avoiding jamming due to different rotational and swinging trajectories of the bottle-splitting blocks 3 and ensuring that the arc rack 43 can smoothly drive multiple bottle-splitting blocks 3 to rotate and swing.
[0044] Specifically, the rotation center of the sliding end 33, which is fixedly connected to the arc rack 43, coincides with the center of the arc rack 43. When the arc rack 43 rotates under the drive of the gear 42, the bottle-separating block 3, which is fixedly connected to the arc rack 43, can rotate synchronously with the arc rack 43 and remain relatively stationary with the arc rack. The sliding end 33, which is movably connected to the arc rack 43, slides along the sliding direction of itself and the rotating end 32 on the arc rack 43. That is to say, the sliding direction of the sliding end 33 sliding with the arc rack 33 is the same as the sliding direction of the sliding end 33 sliding with the rotating end 32. The consistent direction allows the sliding end 33 to slide closer to or further away from the rotating end 33, thus allowing it to slide to adapt to position changes when the arc rack 43 drives it to rotate. When the arc rack 43 rotates under the drive of the gear 42, the sliding end 33, which is in sliding engagement with the arc rack 43, can slide to avoid jamming. At the same time, it ensures that multiple sliding ends 33 always remain parallel and spaced unchanged, ensuring that the size of the bottle-separating channel formed between adjacent bottle-separating blocks 3 does not change. By controlling the rotation and swing of multiple bottle-separating blocks 3 through one arc rack 43, the overall device structure is simpler and the later maintenance cost is reduced.
[0045] Furthermore, a preset gap is left between the bottom end of the bottle dividing block 3 and the top surface of the conveyor belt 1. If the irregularly shaped bottle breaks during the guiding process of the bottle dividing block 3, the fragments of the irregularly shaped bottle can be squeezed out through the gap between the bottom end of the bottle dividing block 3 and the top surface of the conveyor belt 1, preventing the broken irregularly shaped bottle from blocking the guiding channel 5 of the bottle dividing block 3 for the irregularly shaped bottle.
[0046] Furthermore, the irregular bottle rejection assembly also includes a guide channel 5, which is located above the conveyor belt 1. The guide channel 5 is used to guide the movement path of the irregular bottle and correct the angle of the irregular bottle. The bottle outlet end of the guide channel 5 is adjacent to the bottle separating block 3.
[0047] like Figure 2 As shown, in actual operation, irregularly shaped bottles are first discharged onto conveyor belt 1 via a discharge device, and then moved towards the bottle-separating unit under the drive of conveyor belt 1. For some irregularly shaped bottles with a rectangular vertical projection, if the angle of the irregularly shaped bottle is not tilted, the irregularly shaped bottle will not be able to enter the bottle-separating channel or the bottle-out channel. Therefore, a guide channel 5 is set on conveyor belt 1, and the bottle-out end of the guide channel 5 is adjacent to the bottle-separating block 3. After the irregularly shaped bottle is discharged onto conveyor belt 1, it will directly enter the guide channel 5 for straightening, so that the irregularly shaped bottle is at a set angle, thereby ensuring that the irregularly shaped bottle can smoothly enter the bottle-separating channel and the bottle-out channel.
[0048] Specifically, the guide channel 5 consists of two guide bars, which are arranged at intervals on the conveyor belt 1, and the gap between the two guide bars forms the guide channel 5.
[0049] Furthermore, such as Figure 2 As shown, a detection component 6 is provided on the side of the guide channel 5. The detection component 6 is used to detect whether the irregular bottle is in place. There may be relative movement between the irregular bottle and the conveyor belt 1, which is not synchronized. After setting the detection component 6, it can be determined whether the irregular bottle is in place, so as to avoid the bottle dividing block 3 swinging too early or too late and damaging the irregular bottle.
[0050] Specifically, the detection component 6 is a photoelectric switch, and the installation position of the detection component 6 is close to the bottle separating block 3. When the irregularly shaped bottle moves to the detection position, the irregularly shaped bottle will block the beam of the photoelectric switch, so that the photoelectric switch receives the arrival signal and realizes the arrival detection of the irregularly shaped bottle.
[0051] Specifically, the baffle 2, the bottle separating block 3, the drive motor 41, the guide strip, and the detection component 6 are all mounted on the conveyor belt 1 directly above the conveyor belt 1 via a bracket. This is a conventional technical method in the field and will not be described in detail here.
[0052] Specifically, the conveyor belt 1 is a conventional technical means in this field, and this application does not limit it, as long as it can drive the irregularly shaped bottle to move along the set direction.
[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
