Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, and in particular to a bottle angle adjustment device and a bottle angle adjustment method. Background Technology

[0002] A labeling machine is a mechanical device that applies a shrinkable label with a printed pattern to the outside of a bottle and attaches the label to the bottle through heat shrinking or cold shrinking. In existing technology, the position and orientation of the bottles placed on the conveyor belt are random, meaning that the position and angle of the bottles on the conveyor belt are different each time. When labeling irregularly shaped cylindrical bottles (e.g., cylindrical bottles with indentations or protrusions in specific areas) or non-cylindrical bottles (e.g., square bottles with multiple pre-set surfaces) using the aforementioned labeling machine, if the bottle angle deflects, the printed pattern on the label corresponding to the indentations or protrusions, or the printed pattern corresponding to the pre-set surfaces, will also deviate from its corresponding position on the bottle during the labeling process. This affects the integrity of the printed pattern and the aesthetics of the bottle. Summary of the Invention

[0003] Therefore, it is necessary to provide a bottle angle adjustment device and a bottle angle adjustment method to address the above-mentioned technical problems, so as to solve the problems that the printed pattern deviates from the corresponding position on the bottle, thereby affecting the integrity of the printed pattern display and the aesthetics of the bottle.

[0004] One aspect of the present invention relates to a bottle angle adjustment device, comprising a first support, a second support, a first roller pair, a second roller pair, a controller, a sensor device for detecting bottle state information, and a drive device drivenly connected to the first roller pair; the first roller pair and the second roller pair are arranged parallel to each other on opposite sides of a conveyor belt for conveying bottles, the first roller pair and the drive device are mounted on the first support; the second roller pair is mounted on the second support; wherein the first support can be adjusted in a direction transverse to the conveyor belt by a first adjustment mechanism, and the second support can be adjusted in a direction transverse to the conveyor belt by a second adjustment mechanism, wherein an adjustment space is formed between the first roller pair and the second roller pair; the controller is signal-connected to the first adjustment mechanism, the second adjustment mechanism, the drive device, and the sensor device respectively, the controller being used to acquire bottle state information collected by the sensor device and drive the first adjustment mechanism and / or the second adjustment mechanism according to the bottle state information, such that the first roller pair and the second roller pair abut against the bottle, and to drive the drive device to move the first roller pair to adjust the bottle to a desired angle position.

[0005] Another aspect of the present invention relates to a method for adjusting the angle of a bottle using the aforementioned bottle angle adjustment device, the method comprising:

[0006] Real-time acquisition of bottle position information of bottles conveyed on the conveyor belt;

[0007] After confirming that a bottle has been transported into the adjustment space by the conveyor belt based on the bottle position information, the bottle angle information of the bottle in the adjustment space is acquired in real time.

[0008] After confirming that the bottle body within the adjustment space is not at a preset angle based on the bottle body angle information, the first adjustment mechanism is controlled to drive the first roller pair to move toward the second roller pair, and the second adjustment mechanism is controlled to drive the second roller pair to move toward the first roller pair, so that the first roller pair and the second roller pair respectively abut against the opposite sides of the bottle body;

[0009] The drive device is controlled to drive the first roller pair to rotate, so as to rotate the bottle to the preset angle.

[0010] This invention, by setting up a first adjustment mechanism, a second adjustment mechanism, a first roller pair, a second roller pair, and a driving device connecting the first roller pair, determines the optimal positioning of the bottle. When the bottle is confirmed to be conveyed to the adjustment space by the conveyor belt and is not at a preset angle, the first adjustment mechanism drives the first roller pair to move towards the second roller pair, and the second adjustment mechanism drives the second roller pair towards the first roller pair. This ensures that the first and second roller pairs abut against opposite sides of the bottle. Then, the driving device drives the first roller pair to rotate, adjusting the bottle to the preset angle. This invention allows for the uniform adjustment of bottles on the labeling machine conveyor belt to the desired angle before labeling, preventing the printed label pattern from deviating from its corresponding position on the bottle during the labeling process. This improves the adaptability of the labeling machine to various initial bottle states, enhances the integrity of the printed pattern, and improves the aesthetics of the bottle. All adjustments are automated, further increasing production efficiency. Attached Figure Description

Detailed Implementation

[0017] 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, not all, of the embodiments of the present invention. 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.

[0018] like Figure 1As shown, in one embodiment, a bottle angle adjustment device is provided. This device is divided into a first part 100 and a second part 200, which are opposite to each other. Specifically, it includes a first support 120, a second support 220, a first roller pair 300, a second roller pair 400, a controller, a sensor device 600 for detecting bottle state information, and a drive device 500 drivenly connected to the first roller pair 300. The first roller pair 300 and the second roller pair 400 are arranged parallel to each other on opposite sides of a conveyor belt 700 for transporting bottles, forming an adjustment space between them. The first roller pair 300 and the drive device 500 are mounted on the first support 120; the second roller pair 400 is mounted on the second support 220. The controller is signal-connected to the first adjustment mechanism, the second adjustment mechanism, the drive device 500, and the sensor device; and can acquire the bottle state information collected by the sensor device 600. The controller is designed to control the first adjustment mechanism to drive the first support and the first roller pair 300 to move in a direction transverse to the conveyor belt 700 according to the bottle status information; to control the second adjustment mechanism to drive the second support and the second roller pair 400 to move in a direction transverse to the conveyor belt 700, so that the first roller pair and the second roller pair abut against the bottle; and to control the drive device 500 to drive the first roller pair 300 to rotate to adjust the bottle angle.

[0019] Understandably, the bottle angle adjustment device is positioned upstream of the labeling machine at a predetermined location on the conveyor belt 700. An adjustment space is formed within the bottle angle adjustment device. During normal operation, bottles placed on the conveyor belt 700 can sequentially pass through the adjustment space under the conveyor belt's transport. The sensor device 600 is designed to detect the bottle's state information. Here, the state information includes the bottle's angle and position information. The sensor device 600 includes, for example, at least one sensor, preferably at least two sensors. The first sensor detects the bottle's position to determine if a bottle has entered the adjustment space. When a bottle is detected entering the adjustment space, the controller drives the first and second supports to move towards the center, so that the first and second roller pairs are in close contact with the bottle. Then, the first roller pair is driven to rotate, causing the bottle to rotate through friction, thereby achieving angle adjustment. Here, the first roller pair is driven by a drive device, particularly a servo motor. The second roller pair is preferably unpowered, meaning it only serves a supporting or auxiliary function. The second sensor is used to detect features on the bottle, such as specific contour features like edges, protrusions, and recesses. For example, it can be specified that after the bottle enters the adjustment space, it is quickly clamped between the first and second roller pairs and rotated and kneaded between them until the second sensor detects the specific contour feature. Detecting the specific contour feature means the bottle is at the desired angle. At this point, the rotation of the first roller pair is immediately stopped, and the first and second roller pairs are disengaged from the bottle. The bottle is then conveyed downstream by a conveyor belt while maintaining its current state. Both the first and second sensors are preferably designed as photoelectric sensors.

[0020] The sensor device may also include a third sensor, which may also be designed as a photoelectric sensor, for detecting whether the bottle whose angle has been adjusted has left the adjustment space. Preferably, the next adjustment action begins only after the currently adjusted bottle has left the adjustment space. That is, a new bottle is only accepted, clamped, and adjusted after the previous bottle has left the adjustment space.

[0021] It should be noted that the first and third sensors are not strictly necessary. They can also be achieved by appropriately setting the conveyor belt speed, the spacing between bottles on the conveyor belt, and the timing of each adjustment action. For example, the timing of each bottle clamping and rotating action of the bottle angle adjustment device can be adapted to the bottle conveying speed, ensuring that the next bottle is conveyed into the adjustment space just as the previous one is adjusted and leaves. Ideally, a single sensor to detect whether the bottle is adjusted to the correct angle is sufficient. However, using multiple sensors can improve reliability and allow for faster bottle conveying.

[0022] The controller acquires or receives bottle status information collected by sensor device 600, and confirms whether the bottle has been conveyed to the adjustment space by conveyor belt 700 based on the bottle position information, and confirms whether the bottle is at a preset angle based on the bottle angle information. When it is confirmed that the bottle has been conveyed to the adjustment space by conveyor belt 700, the controller controls the first adjustment mechanism to drive the first roller pair 300 to move toward the second roller pair 400, and controls the second adjustment mechanism to drive the second roller pair 400 to move toward the first roller pair 300, so that the first roller pair 300 and the second roller pair 400 respectively abut against the opposite sides of the bottle. Then, the controller controls the drive device 500 to drive the first roller pair 300 to rotate, thereby adjusting the bottle to the preset angle. When the controller receives a signal from the sensor indicating that the bottle is at the desired angle, it stops the operation of the servo motor and disengages the first roller pair and the second roller pair from the bottle.

[0023] When the bottle angle adjustment device is working normally, the distance between the end of the first adjustment mechanism away from the first roller pair 300 and the conveyor belt 700 is relatively fixed. When the first adjustment mechanism drives the first roller pair 300 to move toward the second roller pair 400, the first roller pair 300 also moves relative to the conveyor belt 700 and moves toward the bottle on the conveyor belt 700. The distance between the end of the second adjustment mechanism away from the second roller pair 400 and the conveyor belt 700 is relatively fixed. When the second adjustment mechanism drives the second roller pair 400 to move toward the first roller pair 300, the second roller pair 400 also moves relative to the conveyor belt 700 and moves toward the bottle on the conveyor belt 700. The height of the first roller pair 300 and the second roller pair 400 relative to the conveyor belt 700 can be set according to the height of the bottle body placed on the conveyor belt 700, so that the first roller pair 300 and the second roller pair 400 can respectively abut against the bottle body position, thereby stably abutting against the bottle body.

[0024] Preferably, the first moving distance by which the first adjusting mechanism drives the first roller pair 300 (or the first support) to move toward the second roller pair 400 is proportional to the second moving distance by which the second adjusting mechanism drives the second roller pair 400 (or the second support) to move toward the first roller pair 300. This ensures that after the first roller pair 300 and the second roller pair 400 abut against the bottle on the conveyor belt 700, they are both in a uniform lateral position on the conveyor belt 700. Therefore, after confirming that the lateral position of the bottle on the conveyor belt 700 has shifted, the abutment of the first roller pair 300 and the second roller pair 400 against the bottle can adjust the bottle to a preset lateral position on the conveyor belt 700. The ratio of the first moving distance to the second moving distance can be set according to the required lateral position of the bottle on the conveyor belt 700. Equal first and second moving distances make it easier to control the first and second adjusting mechanisms. At this time, the first moving distance and the second moving distance can be made unequal by adjusting the position of the first adjusting mechanism or the second adjusting mechanism relative to the conveyor belt 700, thereby adjusting the required lateral position of the bottle on the conveyor belt 700.

[0025] In one embodiment, the first roller pair 300 and the second roller pair 400 are respectively arranged parallel to the axis of the bottle placed on the conveyor belt 700, so that after the first roller pair 300 and the second roller pair 400 abut against the opposite sides of the bottle, they will not affect the angle between the axis of the bottle and the conveyor belt 700.

[0026] In one embodiment, a first flexible friction strip or friction belt is fitted onto the first roller pair 300; a second flexible friction strip or friction belt is fitted onto the second roller pair 400. The first roller pair 300 and the second roller pair 400 respectively abut against the opposing sides of the bottle body via the first flexible friction strip or friction belt and the second flexible friction strip / friction belt. After the first flexible friction strip and the second flexible friction strip abut against the bottle body, they can wrap around the opposing sides of the bottle body to a greater extent according to different bottle shapes, thereby improving adaptability to bottle shapes, providing friction, and precisely adjusting the angle of the bottle body.

[0027] like Figure 1As shown, in one embodiment, the first adjustment mechanism includes a first drive cylinder 110 mounted on a first side of the conveyor belt 700, and a drive piston of the first drive cylinder 110 operatively connected to a first support 120. The first roller pair 300 and the drive device 500 are both mounted on the first support 120. The first drive cylinder 110 drives the first support 120 to move the first roller pair 300 and the drive device 500. The second adjustment mechanism includes a second drive cylinder 210 mounted on a second side of the conveyor belt 700, and a drive piston of the second drive cylinder 210 operatively connected to a second support 220. The second roller pair 400 is mounted on the second support 220. The second drive cylinder 210 drives the second support 220 to move the second roller pair 400. It is understood that the first side and the second side are opposite sides of the conveyor belt 700. The first drive cylinder 110 or the second drive cylinder 210 can be a pneumatic cylinder or a hydraulic cylinder.

[0028] like Figure 1As shown, in one embodiment, the first adjusting mechanism further includes a first fixing block 130 fixedly connected to the first drive cylinder 110, and the first bracket 120 slidably mounted on the first fixing block 130; the second adjusting mechanism further includes a second fixing block 230 fixedly connected to the second drive cylinder 210, and the second bracket 220 slidably mounted on the second fixing block 230. It can be understood that the first fixing block 130 or the second fixing block 230 can be adjusted relative to the conveyor belt 700 as needed. The first bracket 120 can be slidably connected to the first fixed block 130 by means of sliding along a slide rail or nesting sliding. The direction of sliding along the slide rail or nesting sliding is the same as the extension and retraction direction of the first drive cylinder 110. This allows the first bracket 120 and the first fixed block 130 to retain only the sliding degree of freedom in the extension and retraction direction of the first drive cylinder 110, while restricting other degrees of freedom. This ensures that the first fixed block 130 provides stable support for the first bracket 120. At the same time, it reduces the force exerted by the first bracket 120 on the drive piston of the first drive cylinder 110 in the non-extension and retraction direction, thus avoiding damage to the first drive cylinder 110 and affecting accuracy. Similarly, the second bracket 220 can be slidably connected to the second fixed block 230 by means of sliding along a slide rail or nesting sliding. The direction of sliding along the slide rail or nesting sliding is the same as the extension and retraction direction of the second drive cylinder 210. This allows the second bracket 220 and the second fixed block 230 to retain only the sliding degree of freedom in the extension and retraction direction of the second drive cylinder 210, while restricting other degrees of freedom. This ensures that the second fixed block 230 provides stable support for the second bracket 220, and at the same time reduces the force exerted by the second bracket 220 on the drive piston of the second drive cylinder 210 in the non-extension and retraction direction, thus avoiding damage to the second drive cylinder 210 and the impact on accuracy.

[0029] In one embodiment, the driving device 500 includes a servo motor 510 and a transmission assembly 520 connected to the output shaft of the servo motor 510; the servo motor 510 drives the first roller pair 300 to rotate via the transmission assembly 520. Understandably, the servo motor 510 is mounted on the first bracket 120, and the transmission assembly 520 is connected to both the servo motor 510 and the first roller pair 300, thereby enabling the servo motor 510 to drive the first roller pair 300 to rotate via the transmission assembly 520. The transmission assembly 520 includes, but is not limited to, one or more of components such as gear sets, sprockets 521, chains 522, or toothed belts and pulleys, as long as precise rotational motion can be transmitted.

[0030] like Figure 1As shown, in one embodiment, the transmission assembly 520 includes a sprocket 521 and a chain 522; both ends of the chain 522 are respectively sleeved on the sprocket 521 and the output shaft of the servo motor 510; the rotation shaft of the sprocket 521 is connected to the rotation shaft of one of the rollers in the first roller pair 300; the servo motor 510 drives the sprocket 521 to rotate via the chain 522, thereby driving the first roller pair 300 to rotate. It can be understood that the chain 522 is an annular chain 522 with its ends connected. The rotation shaft of the sprocket 521 and the rotation shaft of the roller in the first roller pair 300 are located on the same straight line.

[0031] like Figure 2 As shown, in one embodiment, a bottle angle adjustment method applied to the above-mentioned bottle angle adjustment device is also provided, the bottle angle adjustment method comprising the following steps:

[0032] S100, real-time acquisition of bottle position information of the bottles conveyed on the conveyor belt 700. Understandably, a sensor device 600 is installed on the conveyor belt 700 at a position before the bottle angle adjustment device relative to the bottle conveying direction. The sensor device 600 includes a first sensor for detecting bottle position information and a second sensor for detecting bottle angle information.

[0033] S200: After confirming that a bottle has been conveyed into the adjustment space by the conveyor belt 700 based on the bottle position information, the bottle angle information of the bottle within the adjustment space is acquired in real time. It can be understood that once the first sensor detects a bottle, it can be confirmed whether a bottle has been conveyed into the adjustment space by the conveyor belt 700. The second sensor continuously monitors the bottle angle information.

[0034] S300, control the first adjusting mechanism to drive the first roller pair 300 to move toward the second roller pair 400, and control the second adjusting mechanism to drive the second roller pair 400 to move toward the first roller pair 300, so that the first roller pair 300 and the second roller pair 400 respectively abut against the opposing sides of the bottle body.

[0035] S400, the driving device 500 is controlled to drive the first roller pair 300 to rotate until the bottle body within the adjustment space is confirmed to be at a preset angle based on the bottle body angle information. Then, the rotation of the first roller pair is stopped, and the first roller pair and the second roller pair disengage from the bottle body. It can be understood that the preset angle can be set according to the correspondence between the label printing pattern and the bottle body. That is, when the bottle body is at the preset angle, the label printing pattern can be accurately fitted onto the corresponding position on the bottle body during the labeling process. In one embodiment, the bottle body angle information includes the angle information of specific features on the bottle body (such as edges or protrusions). By comparing the angle information of the specific features with the angle information of the preset features (i.e., the angle information of the specific features when the bottle body is at the preset angle), it can be confirmed whether the bottle body within the adjustment space is at the preset angle.

[0036] Understandably, after determining that the bottle has been rotated to the preset angle (the bottle angle information collected in real time can be used to confirm whether the bottle is at the preset angle within the adjustment space), the first adjustment mechanism is controlled to drive the first roller pair 300 to move away from the second roller pair 400, and the second adjustment mechanism is controlled to drive the second roller pair 400 to move away from the first roller pair 300, so that the first roller pair 300 and the second roller pair 400 are separated from the bottle, and the bottle is then transferred to the next workstation.

[0037] The bottle angle adjustment method provided by this invention, upon confirming that the bottle has been conveyed to the adjustment space by the conveyor belt 700, controls the first adjustment mechanism to drive the first roller pair 300 to move toward the second roller pair 400, and controls the second adjustment mechanism to drive the second roller pair 400 to move toward the first roller pair 300, so that the first roller pair 300 and the second roller pair 400 respectively abut against the opposing sides of the bottle. Then, the drive device 500 is controlled to drive the first roller pair 300 to rotate, thereby adjusting the bottle to a preset angle. This invention can uniformly adjust the bottles on the labeling machine conveyor belt 700 to the required angle, thereby preventing the label printing pattern from deviating from the corresponding position on the bottle during the labeling process. This improves the adaptability of the labeling machine to bottles of different shapes, enhances the integrity of the printed pattern display, and improves the aesthetics of the bottle.

[0038] like Figure 3 As shown, in one embodiment, after confirming that a bottle has been conveyed to the adjustment space by the conveyor belt 700 based on the bottle position information in step S200, the method further includes:

[0039] S500: Obtain the lateral distance between the bottle and the target roller pair in the adjustment space, and confirm whether the absolute value of the difference between the lateral distance and the preset lateral distance is less than the preset deviation; the target roller pair refers to the first roller pair 300 or the second roller pair 400. It is understood that when labeling via a labeling machine, the inner circle of the label is generally slightly larger than the outer circle of the bottle, thus allowing for a certain deviation in the position of the bottle on the conveyor belt 700. Therefore, the lateral distance between the bottle and the target roller pair can also allow for a certain deviation, i.e., the preset deviation. The preset lateral distance refers to the preset lateral distance between the bottle conveyed by the conveyor belt 700 and the first roller pair 300 or the second roller pair 400, with the longitudinal direction of the conveyor belt as the reference. The bottle position information includes the lateral position information of the bottle on the conveyor belt 700, i.e., the lateral distance relative to the first roller pair 300 or the second roller pair 400. After the second sensor detects the bottle, the lateral distance between the bottle and the first roller pair 300 or the second roller pair 400 in the adjustment space can be confirmed based on the relative positional relationship between the second sensor and the first roller pair 300 or the second roller pair 400.

[0040] S600, after confirming that the absolute value of the difference is greater than the preset deviation, the first adjusting mechanism is controlled to drive the first roller pair 300 to move toward the second roller pair 400, and the second adjusting mechanism is controlled to drive the second roller pair 400 to move toward the first roller pair 300, so that the first roller pair 300 and the second roller pair 400 respectively abut against the opposing sides of the bottle. It can be understood that in this step, the first adjusting mechanism drives the first roller pair 300 to move a first moving distance toward the second roller pair 400, and the second adjusting mechanism drives the second roller pair 400 to move a second moving distance toward the first roller pair 300. The ratio between the first moving distance and the second moving distance is equal. Therefore, after the first roller pair 300 and the second roller pair 400 abut against the bottle on the conveyor belt 700, both can adjust the bottle to a uniform lateral position on the conveyor belt 700 (when the ratio between the first moving distance and the second moving distance is 1, this lateral position is the first roller pair 300 and the second roller pair 400). For the center position point of 400; when the ratio between the first moving distance and the second moving distance is not equal to 1, the lateral position is a non-center position point between the first roller pair 300 and the second roller pair 400. Thus, after confirming that the absolute value of the difference is greater than the preset deviation, the bottle is adjusted to the preset lateral position on the conveyor belt 700 by the contact between the first roller pair 300 and the second roller pair 400 and the bottle. In this way, the absolute value of the difference between the lateral distance and the preset lateral distance can be adjusted to be less than the preset deviation, so that the bottle is in the correct lateral position on the conveyor belt 700. Understandably, after obtaining the lateral distance between the bottle and the target roller pair in the adjustment space again, and confirming that the absolute value of the difference between the lateral distance and the preset lateral distance is less than or equal to the preset deviation, the first adjustment mechanism is controlled to drive the first roller pair 300 to move away from the second roller pair 400, and the second adjustment mechanism is controlled to drive the second roller pair 400 to move away from the first roller pair 300, so that the first roller pair 300 and the second roller pair 400 are separated from the bottle, and the bottle is then transferred to the next station.

[0041] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
