Description

Technical Field

[0001] The invention relates to the technical field of packaging conveying, in particular to a dial mechanism for changing container spacing online. Background Art

[0002] In the packaging industry, it is often necessary to convey containers such as cans, bottles or boxes at a distance. For example, when the containers on a certain section of the conveyor line are conveyed closely together to the labeling station, it will directly affect the overall labeling effect of the labeling equipment, and it is easy to miss labels or have skewed labels. Therefore, it is necessary to adjust the spacing between the container brackets on the conveyor line in time to meet the processing requirements of subsequent processes.

[0003] The patent publication number of the existing patent application is: CN221810042U, and the publication date is October 8, 2024. The name of the patent is "Speed-adjustable automatic bottle separator". The patent includes a conveyor frame and a servo motor arranged on one side of the conveyor frame, and also includes: a conveyor belt, which is arranged on the inner side of the conveyor frame, and the conveyor belt is set on the outer side of the conveying shaft at the output end of the servo motor; a stepper motor, fixed at the central position of one side of the conveyor frame, and a connecting rod is fixed on the output end of the stepper motor, and a bottle separator plate is set on the outer surface of the connecting rod; an infrared detection module, which is arranged on the side of the conveyor frame close to the stepper motor; a locking mechanism, which is arranged on the outer side of the connecting rod. The utility model can lock and limit the bottle separator plate by setting a reset spring to push the limiting plate outward to engage with the groove on the inner wall of the bottle separator plate, thereby avoiding the deviation of the bottle separator plate. Since the bottle separator plate can be quickly disassembled, the bottle separator plate can be quickly replaced and adjusted according to the different sizes of the metal cans, which can ensure the conveying speed of the bottle separator plate to the metal cans, so as to facilitate subsequent processing.

[0004] The above application has shortcomings. Traditional dial-type spacing adjustment mechanisms mostly use rigid teeth to directly contact the container to achieve equidistant distribution of containers. In actual applications, rigid contact can easily cause surface indentations, deformation, or even damage to thin-walled containers or special-shaped containers. At the same time, the spacing adjustment accuracy is limited by the processing accuracy of the teeth and mechanical wear, and cumulative errors are likely to occur after long-term operation. Existing buffering solutions mostly use independent shock absorbers or pneumatic compensation devices, and neither of these two methods can directly guarantee that there will be no loss of positioning accuracy when pushing the container away, resulting in a complicated mechanism and a response speed that is difficult to match the requirements of high-speed production lines.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0023] Please refer to Figure 1-9A dial mechanism for changing the spacing between containers online provided by an embodiment of the present invention includes a conveying platform 1 and an electric dial 2, which is installed on one side of the conveying platform 1. The outer edge of the electric dial 2 is provided with a tooth-shaped curved surface 201 that is adapted to the shape of the container. A receiving groove 202 is opened in the recess of the tooth-shaped curved surface 201. A buffer plate 3 is elastically hinged in the receiving groove 202. A toggle locking component 4 is installed on the bottom surface of the electric dial 2. The toggle locking component 4 is used to limit the rotation of the buffer plate 3. Before the electric dial 2 toggles the container through the tooth-shaped curved surface 201, the buffer plate 3 first contacts the container, so that the buffer plate 3 enters the receiving groove 202 and is locked by the toggle locking component 4.

[0024] Specifically, a conveyor belt 101 and anti-deviation adjustment guardrails 102 located on both sides of the top of the conveyor belt 101 are installed on the conveyor platform 1. The outer edge of the electric dial 2 is designed as a continuously distributed tooth-shaped curved surface 201. The concave shape of each tooth-shaped curved surface 201 matches the outer contour of the container to be distributed (such as a bottle body or a can body) to ensure uniform force during contact. The container is translated by the conveyor belt 101 to the position of the electric dial 2. At this time, the container is confined in the space formed by the anti-deviation adjustment guardrail 102 and the tooth-shaped curved surface 201 of the electric dial 2. The container is restricted to move horizontally as required. The current tooth profile curvature of the electric dial 2 is a gentle section with a small curvature. The container is subject to a small lateral thrust and mainly relies on the translation force of the conveyor line to move. The distance between adjacent containers is naturally widened. The electric dial 2 accelerates and rotates to a steep section with a large curvature. At this time, the lateral thrust of the electric dial 2 on the container is enhanced, forcing the container to accelerate translation and the distance is reduced. After the container is out of the tooth profile curve of the electric dial 2, the speed of the electric dial 2 is adjusted to match the linear speed of the electric dial 2 with the linear speed of the conveyor line. The container translates at a constant speed and the distance is locked. When the curvature of the curved surface is small or close to a circle, the electric dial 2 rotates the container and basically stops on the curved surface, which is a stage of waiting to open the spacing. The distance between the containers tends to be larger. The buffer plate 3 pops outward under normal conditions and can retract into the receiving groove 202 when under pressure. Before the container contacts the tooth-shaped curved surface 201, it first flexibly collides with the buffer plate 3. After being pressed, the buffer plate 3 retracts into the receiving groove 202 and absorbs the impact energy to achieve buffering. The locking assembly 4 is turned to correspond to the position setting of each buffer plate 3. When the buffer plate 3 flips over, After rotating and completely entering the accommodating groove 202, the locking assembly 4 is turned to automatically rigidly lock the buffer plate 3. After being locked, the buffer plate 3 and the tooth-shaped curved surface 201 form a rigid whole. When the electric dial 2 rotates, the tooth-shaped curved surface 201 accurately dials the container to force the container spacing to be adjusted. During the distribution process, the buffer plate 3 always remains in an inserted state to prevent the buffer plate 3 from being displaced and contacting the container due to external force, thereby ensuring the distribution positioning accuracy and enabling the locking action to be completed after the container is effectively buffered, thereby reducing the container breakage and wear rate.

[0025] Compared with the prior art, the embodiment of the present invention realizes flexible buffering in the process of contacting the container by means of a buffer pad 3 which is elastically hinged and is provided in the depression of the tooth-shaped curved surface 201, and cooperates with the synergistic effect of the bottom surface sliding locking assembly 4, so that the buffer pad 3 can be switched between the flexible buffering and rigid positioning modes, thereby ensuring the dialing accuracy and improving the attenuation rate of the impact force of the tooth-shaped curved surface 201 on the electric dial 2 on the container, thereby reducing the breakage rate and wear rate of the container. The working mechanism of buffering first and then locking overcomes the mechanical damage defect of traditional rigid teeth and avoids the loss of positioning accuracy caused by the pure elastic mechanism, and is suitable for high-speed pitch adjustment production lines.

[0026] In a further technical solution of the present invention, the electric dial 2 is fixed to the conveyor platform 1 through a mounting frame 203, and the bottom surface of the electric dial 2 is connected to a servo motor 204 through a reducer. Specifically, the servo motor 204 drives the electric dial 2 through the reducer to apply acceleration and deceleration to the container. While the tooth curve is spacing, the container is affected by the speed of the servo motor 204, and the container is accelerated and decelerated. Once the container is out of the restriction of the electric dial 2 curve, it is immediately controlled only by the conveyor line. The conveyor line speed matches the linear speed of the servo motor 204. At this time, the linear speed is the target value to be achieved per unit time, that is, the spacing change is completed, and the container is steadily and gradually accelerated on the conveyor belt. When the container diameter is different, and the production line capacity is different, the tooth shape of the container electric dial 2 and the speed value of the servo motor 204 are matched to achieve a suitable container output spacing.

[0027] In a further technical solution of the present invention, one end of the buffer pad 3 is vertically fixedly connected to a hinge shaft 301, and both ends of the hinge shaft 301 are rotatably connected to the inner wall of the receiving groove 202, and the hinge shaft 301 is symmetrically sleeved with a buffer torsion spring 302, and both ends of the buffer torsion spring 302 are respectively connected to the inner wall of the receiving groove 202 and the buffer pad 3. Specifically, the axis of the hinge shaft 301 is perpendicular to the plane of the buffer pad 3, and the buffer pad 3 can rotate freely around the axis of the hinge shaft 301. The receiving groove 202 is not only used to hide the buffer pad 3, but also used to limit the rotation of the buffer pad 3 When the buffer plate 3 is rotated to the corresponding angle under pressure, the container contacts the tooth-shaped surface 201 and no longer pushes the buffer plate 3, thereby preventing the buffer torsion spring 302 from failing due to excessive compression. When the container enters the tooth-shaped surface 201 area of ​​the dividing disk, it first contacts the buffer plate 3. The lateral pressure exerted by the container on the buffer plate 3 drives it to rotate inward around the hinge axis 301, compressing the upper and lower symmetrical buffer torsion springs 302. The upper and lower buffer torsion springs 302 deform synchronously, providing uniform torque, converting impact energy into elastic potential energy, and increasing the attenuation rate of impact force.

[0028] In a further technical solution of the present invention, a limiting rod 303 is fixedly connected to the bottom surface of the buffer plate 3, and an arc-shaped guide groove 205 matching the limiting rod 303 is formed through the bottom of the accommodating groove 202. Specifically, the arc radius of the arc-shaped guide groove 205 is consistent with the rotation trajectory of the buffer plate 3. The arc-shaped guide groove 205 and the limiting rod 303 cooperate with each other to limit the maximum rotation angle of the buffer plate 3, and can also prevent the problem of excessive deviation of the movement trajectory of the buffer plate 3 due to unstable connection of the hinge shaft 301. When the container hits the buffer plate 3, it rotates around the hinge shaft 301, and the limiting rod 303 slides along the arc-shaped guide groove 205 toward the center of the electric dial 2. The buffer torsion spring 302 provides elastic resistance to absorb impact energy. The arc-shaped guide groove 205 constrains the trajectory of the limiting rod 303 to ensure that the rotation angle and direction of the buffer plate 3 are controllable to avoid deflection or jamming.

[0029] In a further technical solution of the present invention, the toggle locking assembly 4 includes a locking rod 401 elastically hinged to the bottom surface of the electric dial 2, a torsion spring is installed between the locking rod 401 and the electric dial 2, one end of the locking rod 401 is fixedly connected to an anti-detachment hook 402, the anti-detachment hook 402 is located below the arc guide groove 205, and the anti-detachment hook 402 is engaged with the limit rod 303. Specifically, the locking rod 401 and the anti-detachment hook 402 are combined into an L-shaped structure, the anti-detachment hook 402 is tilted and located directly below the arc guide groove 205, and its movement trajectory intersects with the sliding path of the limit rod 303. A wear-resistant layer is provided on the inner side of the anti-detachment hook 402, which can reduce the collision noise and wear with the limit rod 303. In the process of toggling the container, the original The buffer plate 3 outside the accommodating groove 202 is forced to rotate into the accommodating groove 202. During the rotation, the limit rod 303 will pass through and push the anti-detachment hook 402, forcing the locking rod 401 to rotate and allow the anti-detachment hook 402 to move away from the moving path of the limit rod 303. After the limit rod 303 is moved away, the locking rod 401 rotates under the action of the torsion spring, so that the anti-detachment hook 402 is reset to prevent the limit rod 303 from moving outward. The position of the buffer plate 3 is locked by limiting the limit rod 303, thereby ensuring that when the tooth curve contacts the container and sends it, it will not be affected by the buffer plate 3, resulting in a decrease in the spacing accuracy. In the high-speed distribution scenario, sensor-free triggering locking is achieved, which not only simplifies the control system, but also improves the reliability of the locking action.

[0030] In a further technical solution of the present invention, a tray 5 is fixedly connected to the mounting frame 203, the tray 5 is located below the electric dial 2, and an unlocking protrusion 501 that abuts against the locking rod 401 is fixedly connected to the outer side of the tray 5. When the locking rod 401 is squeezed and forced to flip by the unlocking protrusion 501, the buffer plate 3 rotates to the outside of the accommodating groove 202. Specifically, the tray 5 coincides with the central axis of the electric dial 2, and the unlocking protrusion 501 on the tray 5 is used to guide the locking rod 401 to flip. When the electric dial 2 rotates to distribute the container, the anti-detachment hook 402 of the locking rod 401 is engaged with the limit rod 303, and the buffer plate The plate 3 is retracted into the accommodating groove 202, and the tooth-shaped curved surface 201 directly contacts the container to complete the rigid separation. Then the locking rod 401 rotates to the unlocking protrusion 501 position. When one end of the locking rod 401 abuts against the unlocking protrusion 501, it rotates around the hinge point, so that the anti-detachment hook 402 at the other end of the locking rod 401 flips outward to release the limit rod 303, so that the buffer pad 3 rotates toward the outside of the accommodating groove 202 under the action of the buffer torsion spring 302, so as to play a buffering role when contacting the next container to be dispensed. The locking and unlocking are triggered by the rotation angle control of the electric dial 2, making it suitable for high-speed continuous operation environment.

[0031] In a further technical solution of the present invention, an elastic brush rod 6 for cleaning the tooth-shaped curved surface 201 and the inner side of the buffer pad 3 is slidably installed on the top of the mounting frame 203. After the buffer pad 3 contacts the container, it passes through the elastic brush rod 6 and the unlocking protrusion 501 in sequence. Specifically, after the buffer pad 3 contacts the container, it passes through the elastic brush rod 6 and the unlocking protrusion 501 in sequence as the electric dial 2 rotates, forming a continuous action of cleaning and then unlocking. After the tooth-shaped curved surface 201 on the electric dial 2 and the buffer pad 3 are pushed away from the container, they contact the elastic brush rod 6 again. Under the abutment of the tooth-shaped curved surface 201, the elastic brush rod 6 moves back and forth, and driven by the elastic member, it always sticks to the outer side of the tooth-shaped curved surface 201 and the buffer plate 3, scrapes off the dust attached to their surface and some waste brought by the container, avoids the accumulation of debris on the buffer plate 3 and the tooth-shaped curved surface 201, ensures that the two fit closely with the container, and unlocks the buffer plate 3 after cleaning, reduces the number of reciprocating rotations of the buffer plate 3, avoids collision between the buffer plate 3 and the elastic brush rod 6, and increases their respective service life.

[0032] In a further technical solution of the present invention, a chip removal groove 206 is provided at the bottom of the accommodating groove 202, a cover plate 7 for covering the chip removal groove 206 is elastically connected to the bottom of the electric dial 2, a plurality of pairs of limit frames matching the cover plates 7 are installed on the electric dial 2, a top spring is installed between the limit frame and the cover plate 7, a pulling rod 701 is hinged on one side of the cover plate 7, one end of the pulling rod 701 passes through the locking rod 401 and is fixedly connected with an anti-slip column 702, the outer wall of the anti-slip column 702 is in contact with the side of the locking rod 401, specifically, the chip removal groove 206 is arc-shaped, and its position corresponds to the outer side after the buffer pad 3 completely enters the accommodating groove 202, the dust and other debris cleaned up by the elastic brush rod 6 will fall into the chip removal groove 206, and since the chip removal groove 206 has a cover plate 7 at the bottom, the debris can be temporarily stored in the chip removal groove 206. When the disk 2 rotates to allow the locking rod 401 and the unlocking protrusion 501 to contact and trigger the unlocking of the buffer pad 3, the locking rod 401 flips around the hinge point, and the pulling rod 701 is affected by the interference between the anti-slip column 702 and the locking rod 401. As the locking rod 401 swings, it is pulled, and the pulling rod 701 pulls the cover plate 7 to overcome the preload force of the top spring, opening the chip discharge groove 206 to discharge dust and other debris to the designated area. When the locking rod 401 is unlocked, that is, after cleaning is completed, the cover plate 7 is triggered to open, thereby avoiding the leakage of debris during the distribution process, improving the sanitation compliance rate, and being suitable for production lines with high sanitation standards. At the same time, when the locking rod 401 and the unlocking protrusion 501 are staggered, the top spring can also be used to push the cover plate 7 to use the pulling rod 701 to pull the locking rod 401, so that the locking rod 401 can be further quickly and stably reset.

[0033] In a further technical solution of the present invention, a reciprocating cleaning component 9 in contact with the top surface of the container is installed on the other side of the conveyor platform 1. The reciprocating cleaning component 9 is connected to the electric dial 2 in transmission. Specifically, when the electric dial 2 rotates, the reciprocating cleaning component 9 is driven to reciprocate and clean the top surface of the container. Through mechanical transmission synchronization and elastic adaptive design, this solution can complete efficient cleaning of the top surface of the container while performing the sorting operation. It is particularly suitable for production scenarios in the food, medicine and other industries that have strict requirements on the cleanliness of packaging containers, and is more conducive to container compliance operations.

[0034] In a further technical solution of the present invention, the reciprocating cleaning assembly 9 includes a support frame 901 installed on the other side of the conveying table 1. A first driven gear 902 and a second driven gear 903 that rotate synchronously are installed inside the support frame 901. A synchronous belt is installed between the first driven gear 902 and the second driven gear 903 to achieve synchronous rotation. The top of the electric dial 2 is fixedly connected with a transmission gear disc 207. A plurality of sector teeth 208 meshing with the first driven gear 902 are annularly distributed on the edge of the transmission gear disc 207, and the positions of the sector teeth 208 correspond to the depressions of the tooth profile surface 201. A return torsion spring 904 is installed between the first driven gear 902 and the support frame 901. A pair of cleaning brushes 905 respectively meshing with both sides of the second driven gear 903 are installed inside the support frame 901. Specifically, the support frame 901 is fixed to the other side of the conveying table 1 by bolts. The axes of the first driven gear 902 and the second driven gear 903 inside the support frame 901 are parallel. The transmission gear disc 207 is coaxially fixed with the electric dial 2, and a plurality of sector teeth 208 are annularly distributed on the outer edge, and their positions correspond one by one to the depressions of the tooth profile surface 201 of the electric dial 2, ensuring that the sector teeth 208 enter the meshing area before the sorting action is completed. When the tooth profile surface 201 of the electric dial 2 pushes the container, the corresponding sector teeth 208 at the top of the electric dial 2 rotate with the transmission gear disc 207 to the meshing position with the first driven gear 902. The sector teeth 208 push the first driven gear 902 to rotate, and then drive the second driven gear 903 to rotate synchronously through the synchronous belt, driving the two cleaning brushes 905 to reciprocate, so that the two cleaning brushes 905 reciprocally clean the top surface of the container. When the sector teeth 208 disengage from the first driven gear 902, the return torsion spring 904 drives the first driven gear 902 and the second driven gear 903 to rotate back, driving the two cleaning brushes 905 to move in the other direction respectively, completing a reciprocating cleaning stroke. The phase of the sector teeth 208 is synchronized with the depression of the tooth profile surface 201, ensuring that the cleaning action is triggered only before the tooth profile curve completes the feeding, avoiding interfering with the sorting accuracy. The cleaning brushes 905 can ensure the cleanliness of the container end cover, facilitating marking. The pair of cleaning brushes 905 move synchronously, which can avoid affecting the normal operation due to the damage of one of the cleaning brushes 905.
