Description

Technical Field

[0001] The utility model relates to the technical field of automated packaging bottle production, in particular to a bottle rotation positioning device. Background Art

[0002] Looking at the various bottled beverages, cosmetics, and water on the market, the exteriors of the bottles are often laser-printed or affixed with labels of varying shapes and colors. However, during bottle marking, labeling, or final production inspection, different information or labels may need to be applied to different locations on the bottle. Alternatively, during final production inspection, the bottle's orientation needs to be aligned for packing, requiring bottle rotation on the production line. Currently, traditional bottle positioning methods rely on manual alignment or robotic manipulation. Manual operations are labor-intensive and inefficient, while robotic manipulation is costly and lacks accuracy. Traditional bottle rotation methods typically remove the bottle from the conveyor belt through a separate mechanism, rotate it, and then transfer it back to the conveyor. This typically involves a complex structure, and during this process, bottle rotation can interfere with the conveyor's movement, making it difficult to maintain proper spacing between adjacent bottles.

[0003] Therefore, it is necessary to design a structure that can keep the bottle body from leaving the conveyor belt during rotation and ensure the stability of the bottle body, so as to facilitate stable rotation of the bottle body. Utility Model Content

By separately setting a bottle body positioning mechanism and a bottle body rotation mechanism, the bottle body is positioned by using the bottle body positioning mechanism while the bottle body rotates, ensuring that it does not leave the conveyor belt while also being able to achieve stable rotation.

[0005] Technical solution: The utility model provides a bottle body rotation and positioning device, including a conveyor belt for transmitting the bottle body, and a bottle body positioning mechanism and a bottle body rotation mechanism are arranged on both sides of the conveyor belt. The bottle body positioning mechanism is used to position the bottle body, and the bottle body rotation mechanism controls the rotation of the bottle body when the bottle body positioning mechanism positions the bottle body.

[0006] Furthermore, the bottle body positioning mechanism and the bottle body rotating mechanism are arranged on a synchronous longitudinal driving mechanism, and the synchronous longitudinal driving mechanism drives the bottle body positioning mechanism and the bottle body rotating mechanism to synchronously approach or move away from the bottle body.

[0007] Furthermore, the bottle body positioning mechanism includes a pair of rollers rotatably connected to the positioning bracket, the rollers are vertically arranged, and when the bottle body positioning mechanism positions the bottle body, the pair of rollers are in contact with the bottle body and the distance between the pair of rollers is smaller than the diameter of the bottle body.

[0008] Furthermore, a spacing adjustment component is also provided on the positioning bracket, and the spacing adjustment component includes a connecting plate fixed to the positioning bracket, and a pair of connecting rods are provided on the connecting plate. The pair of connecting rods are connected to the roller support through a pair of clamping blocks, and the roller is rotatably connected to the roller support, and the clamping block can slide left and right on the pair of connecting rods.

[0009] Furthermore, the bottle body rotation mechanism includes a bottle body rotation bracket, the bottle body rotation bracket is provided with a pulley assembly, and the pulley assembly is provided with a driving motor for driving the pulley assembly. When controlling the rotation of the bottle body, one side of the pulley assembly contacts the bottle body.

[0010] Furthermore, the synchronous longitudinal drive mechanism includes a longitudinal slide rail, a first drive member and a second drive member. The bottle body positioning mechanism and the bottle body rotation mechanism are both arranged on the longitudinal slide rail. The first drive member and the second drive member respectively drive the bottle body positioning mechanism and the bottle body rotation mechanism to slide on the longitudinal slide rail.

[0011] Furthermore, the first driving member is a first driving cylinder, and the execution end of the first driving cylinder is connected to the positioning bracket.

[0012] Furthermore, the second driving member is a second driving cylinder, and the execution end of the second driving cylinder is connected to the bottle body rotating bracket.

[0013] Furthermore, the synchronous longitudinal drive mechanism is also provided with a fine-tuning component, and the fine-tuning component includes a threaded column, and the threaded column is arranged on the support plate for installing the longitudinal slide rail. The two ends of the threaded column are rotatably connected to the bearing seat of the support plate through bearings, and an adjustment plate is threadedly connected to the threaded column; the adjustment plate is arranged on the longitudinal slide rail after being connected to the first drive member or the second drive member.

[0014] Furthermore, the synchronous longitudinal drive mechanism is also provided on a transverse sliding assembly, and the transverse sliding assembly and the conveying belt have the same transmission direction and the transmission speeds of the two are also the same.

[0015] Furthermore, a color mark sensor facing the bottle body is provided on one side of the conveyor belt, and the color mark sensor is connected to the PLC controller.

[0016] Beneficial effects:

[0017] 1. The utility model sets the bottle body positioning mechanism and the bottle body rotating mechanism in a position facing each other, so that when the bottle body is rotated by using the bottle body rotating mechanism, the bottle body positioning mechanism can position the bottle body, which can ensure the stability of the bottle body and realize the rotation of the bottle body.

[0018] 2. The bottle body positioning mechanism of the present invention is realized by a pair of rollers, which can limit the bottle body between the two rollers to ensure the verticality of the bottle body, and the rollers do not affect the rotation process of the bottle body.

[0019] 3. The utility model sets a pair of rollers on the positioning bracket, and the distance between the rollers and the conveyor belt can be adjusted by the synchronous longitudinal drive mechanism. In this way, when the bottle body needs to be positioned, the positioning bracket is driven by the first drive cylinder to move on the synchronous longitudinal drive mechanism and then controlled to be close to the conveyor belt, without affecting the transmission of the bottle originally on the conveyor belt.

[0020] 4. The utility model sets a pair of rollers on the connecting rod through a clamping block, so that the clamping block can drive the rollers to slide left and right on the connecting rod, and the distance between the pair of rollers can be adjusted. It can adapt to the rotation and positioning operations of bottles with different directions and has strong adaptability.

[0021] 5. The utility model realizes the rotation of the bottle body through the pulley assembly. The pulley assembly is driven by the driving motor. The belt directly contacts the bottle body. The rotation of the belt drives the bottle body to rotate, thereby realizing stable rotation of the bottle body.

[0022] 6. The bottle body rotating bracket of the utility model is arranged on the synchronous longitudinal drive mechanism, and the bottle body rotating bracket can be driven to slide on the synchronous longitudinal drive mechanism by the second drive cylinder, thereby further realizing that the bottle body rotating bracket drives the pulley assembly to approach / move away from the bottle body without affecting the transmission of the bottle on the original conveyor belt.

[0023] 7. The utility model also arranges the synchronous longitudinal drive mechanism on the transverse sliding assembly. The transverse sliding assembly and the conveying direction of the conveyor belt are consistent and the transmission speed of the two are also consistent. In this way, during the rotation of the bottle body, the bottle body can be kept on the conveyor belt, and the transverse sliding assembly drives the bottle body positioning mechanism and the bottle body rotation mechanism thereon to move with the conveyor belt, which can not only ensure the stable rotation of the bottle body, but also maintain a forward inertia. Even after the rotation is completed, the bottle body still maintains a forward inertia and will not affect the transmission of other bottles on the conveyor belt.

[0024] 8. The present invention further provides an adjustable threaded column on the support plate of the synchronous longitudinal drive mechanism. The rotation of the threaded column can realize the forward and backward movement of the adjustment plate on the threaded column, so that the adjustment plate can further adjust the position of the first drive member or the second drive member on the synchronous longitudinal drive mechanism. In this way, the distance between the bottle body positioning mechanism and the bottle body rotation mechanism and the bottle body can be relatively fine-tuned according to the size of the bottle body diameter, ensuring that the bottle body positioning mechanism and the bottle body rotation mechanism are tightly attached to the bottle body after the first drive member and the second drive member are driven.

[0025] 9. The present invention also provides a color mark sensor on one side of the conveyor belt to detect the direction of the bottle body through the color mark sensor. When the color mark sensor detects the color mark set in the bottle body or does not detect the color mark set in the bottle body, the bottle body positioning mechanism and the bottle body rotation mechanism are controlled by the PLC controller to work or stop working, so that the bottle body can be uniformly rotated to the actual required direction, realizing automation.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0033] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0034] The utility model discloses a bottle body rotation and positioning device, comprising a conveyor belt 3 for conveying bottle bodies 6, a bottle body positioning mechanism 4 and a bottle body rotation mechanism 5 are arranged opposite to each other on both sides of the conveyor belt 3, the bottle body positioning mechanism 5 and the bottle body rotation mechanism 4 are arranged on a frame 1, the bottle body positioning mechanism 4 is used to position the bottle body, and the bottle body rotation mechanism 5 controls the rotation of the bottle body 6 when the bottle body positioning mechanism 4 positions the bottle body 6.

[0035] The bottle body positioning mechanism 4 and the bottle body rotating mechanism 5 are arranged on the synchronous longitudinal driving mechanism, and the synchronous longitudinal driving mechanism drives the bottle body positioning mechanism 4 and the bottle body rotating mechanism 5 to synchronously approach or move away from the bottle body 6 .

[0036] See also Figure 2 and Figure 3 The bottle body positioning mechanism 4 includes a pair of rollers 402 rotatably connected to the positioning bracket 401. The rollers 402 are vertically arranged. When the bottle body positioning mechanism positions the bottle body 6, the pair of rollers 402 contact the bottle body 6 and the distance between the pair of rollers 402 is less than the diameter of the bottle body 6.

[0037] In this embodiment, the synchronous longitudinal drive mechanism uses a longitudinal slide rail 404, and the positioning bracket 401 is also set on the longitudinal slide rail 404. The longitudinal slide rail 404 is set perpendicular to the conveyor belt 3 and has a first drive component on it that drives the positioning bracket 401 to slide on the longitudinal slide rail 404.

[0038] In this embodiment, the first driving member is configured as a first driving cylinder 403, and the actuator end of the first driving cylinder 403 is connected to the positioning bracket 401. When the first driving cylinder 403 is controlled to work, the positioning bracket 401 can be pulled or pushed closer to or away from the conveyor belt 3.

[0039] To increase applicability, in this embodiment, a spacing adjustment assembly is provided on the positioning bracket 401. The spacing adjustment assembly includes a connecting plate 408 fixed to the positioning bracket 401. A pair of connecting rods 405 are provided on the connecting plate 408. The pair of connecting rods 405 are connected to a roller support 407 via a pair of clamping blocks 406. The roller 402 is rotatably connected to the roller support 407, and the clamping block 406 can slide left and right on the pair of connecting rods 405. The pair of connecting rods 405 are arranged side by side in an upper and lower direction. A clamping block 406 is clamped on the pair of connecting rods 405. The clamping block 406 can drive the roller support 407 to slide left and right on the connecting rod 405. The clamping block 406 can be relatively fixed by bolts and nuts. In this way, the distance between the two rollers 402 can be adjusted. If the diameter of the bottle body 6 is small, the distance between the two rollers 402 can be reduced to make the device adaptable to bottles of different sizes.

[0040] The bottle body rotation mechanism 5 includes a bottle body rotation bracket 501, which is equipped with a pulley assembly 502. The pulley assembly 502 is equipped with a drive motor 503 that drives the pulley assembly 502. When controlling the rotation of the bottle body 6, one side of the pulley assembly 502 contacts the bottle body 6. In this embodiment, the pulley assembly 502 uses a belt to cooperate with the driving and driven pulleys. The drive motor 503 drives the driving pulley to rotate, which in turn rotates the driven pulley via the belt. During the belt rotation, the belt contacts the bottle body 6, driving the bottle body 6 to rotate.

[0041] The bottle body rotating bracket 501 is arranged on a synchronous longitudinal drive mechanism, that is, on a longitudinal slide rail 404. The longitudinal slide rail 404 is arranged perpendicular to the conveyor belt 3 and is provided with a second driving member for controlling the bottle body rotating bracket 501 to slide on the longitudinal slide rail 404.

[0042] In this embodiment, the second driving member is a second driving cylinder 504 , and an actuating end of the second driving cylinder 504 is connected to the bottle body rotating bracket 501 .

[0043] It should be noted here that in this embodiment, the positioning bracket 401 and the bottle body rotating bracket 501 are arranged on a synchronous longitudinal drive mechanism, that is, the positioning bracket 401 and the bottle body rotating bracket 501 are both arranged on the longitudinal slide rail 404, but this application is not limited to the longitudinal slide rail 404. The positioning bracket 401 and the bottle body rotating bracket 501 can also be arranged on the slide rail separately and controlled separately. It is only necessary to control the two slide rails to work simultaneously.

[0044] To accommodate different bottle body 6 sizes, it is sometimes necessary to fine-tune the distance between the positioning bracket 401, the bottle body rotating bracket 501, and the conveyor belt 3 to facilitate precise driving of the first and second driving members. In this embodiment, a threaded post 506 is further provided on the support plate 505 on which the longitudinal slide 404 is provided. Both ends of the threaded post 506 are mounted on bearing seats 507 of the support plate 505 via bearings. An adjustment plate 508 is threadedly connected to the threaded post 506. After the adjustment plate 508 is connected to the first driving member, it is mounted on the longitudinal slide 404. Furthermore, the threaded post 506 can be rotated by a handle 510 to fine-tune the adjustment plate 508. When the adjustment plate 508 is adjusted longitudinally, it drives the first driving member (first driving cylinder 403) to which it is connected to slide on the longitudinal slide 404, further fine-tuning the distance between the positioning bracket 401 and the conveyor belt 3.

[0045] Alternatively, the adjustment plate 508 may be connected to the second driving member (second driving cylinder 504) and then disposed on the longitudinal slide rail 404. This allows for fine adjustment of the adjustment plate 508. When the adjustment plate 508 is longitudinally adjusted, it drives the second driving member (second driving cylinder 504) to which it is connected to slide on the longitudinal slide rail 404, thereby further fine-tuning the distance between the bottle body rotating bracket 501 and the conveyor belt 3.

[0046] To coordinate with the movement of the conveyor belt 3, the present invention further provides a longitudinal slide rail 404 on a transverse sliding assembly. The transverse sliding assembly and the conveyor belt 3 are aligned in the same transmission direction and at the same transmission speed. In this embodiment, the transverse sliding assembly is a transverse slide rail 509. The longitudinal slide rail 404 directly drives the structure on it to slide on the transverse slide rail 509.

[0047] In order to facilitate the control of the rotation angle of the bottle body 6, the utility model is also provided with a color mark sensor 7 facing the bottle body 6 on one side of the conveyor belt 3. The color mark sensor 7 is connected to the PLC controller 2. In this embodiment, the color mark sensor 7 is vertically fixed by a pillar, facing the bottle body 6. During the operation of the conveyor belt 3, the color mark sensor 7 illuminates each bottle body 6. The bottle body 6 is provided with a color mark mark point. When the color mark sensor 7 does not detect the color mark mark point on the bottle body 6, the PLC controller 2 controls the first driving cylinder 403, the second driving cylinder 504 and the driving motor 503 to start working, that is, the bottle body positioning mechanism 4 and the bottle body rotating mechanism 5 work to realize the rotation of the bottle body 6. When it rotates to the point where the color mark sensor 7 detects the color mark mark point, the color mark sensor 7 sends a signal to the PLC controller 2. The PLC controller 2 controls the first driving cylinder 403, the second driving cylinder 504 and the driving motor 503 to stop working, and the rotation of the bottle body 6 ends.

[0048] In addition, in this embodiment, the longitudinal slide rail 404 is also provided on the transverse sliding assembly. During the rotation of the bottle body 6, the longitudinal slide rail 404 drives the bottle body positioning mechanism 4 and the bottle body rotation mechanism 5 to move along with the conveyor belt 3. During this process, the support for fixing the color mark sensor 7 is also provided on the transverse sliding assembly and moves along with the transverse sliding assembly.

[0049] Working principle:

[0050] 1. Place the bottles 6 on the conveyor belt 3 for transmission in sequence, and control the first driving cylinder 403 and the second driving cylinder 504 to move so that the roller 402 and the pulley assembly 502 are away from the conveyor belt 3.

[0051] 2. When the bottle body 6 is transferred to the rotation position, the first driving cylinder 403 and the second driving cylinder 504 are activated to slide the positioning bracket 401 and the bottle body rotating bracket 501 on the longitudinal slide rail 404, close to the conveyor belt 3, and the roller 402 clamps the bottle body 6. The pulley assembly 502 drives the bottle body 6 to rotate. At this time, the conveyor belt 3 can be controlled to stop moving. After the rotation action is completed, the conveyor belt 3 can be restarted.

[0052] 3. When the bottle body rotates, the first driving cylinder 403 and the second driving cylinder 504 are actuated, and the positioning bracket 401 and the bottle body rotating bracket 501 slide on the longitudinal slide rail 404, away from the conveyor belt 3, without affecting the conveyor belt 3 to continue working.

[0053] If the conveyor belt 3 cannot stop and needs to continue to move, the positioning bracket 401 and the bottle body rotating bracket 501 are slid on the longitudinal slide rail 404 close to the conveyor belt 3 and clamp the bottle body 6. At the same time, the transverse slide rail 509 is controlled to move, so that the pulley assembly 502 drives the bottle body 6 to rotate while the bottle body 6 continues to move on the conveyor belt 3. After the bottle body 6 rotates, the first drive cylinder 403 and the second drive cylinder 504 are actuated, and the positioning bracket 401 and the bottle body rotating bracket 501 slide on the longitudinal slide rail 404 away from the conveyor belt 3. At the same time, the transverse slide rail 509 is actuated to return to the starting position to continue the next round of bottle body 6 rotation operation.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
