Description

Technical Field

[0001] This application relates to the field of glass bottle manufacturing technology, and more specifically, to an automatic reversing device and an automatic reversing transport system. Background Technology

[0002] During the manufacturing process of glass bottles, necessary inspections and packaging are required before they leave the factory. Currently, glass bottles transported by conveyor belts, such as vials, have a structure consisting of a bottle neck, bottle body, and bottle bottom. However, some inspection devices, packaging devices, or other devices require the vials to be rotated 180° so that the bottle neck faces the opposite direction before proceeding to the next process.

[0003] In traditional production processes, manual reversing is often used. However, manual reversing is slow, has a high error rate, low production efficiency, and high labor intensity for workers. Therefore, some production lines use specialized mechanical equipment for reversing, such as robotic arms. However, mechanical reversing equipment has a complex structure, is prone to failure, has high manufacturing and maintenance costs, takes a long time to repair, and the reversing speed does not match the actual production line speed. If a part is missed and not reversed, it will cause great trouble for subsequent packaging and warehousing. In addition, some robotic arms are also prone to problems with insecure gripping, which can easily cause glass bottles to fall and break, posing safety hazards to personnel and equipment.

[0037] Figures 1 to 8 An embodiment of the automatic commutation device of this application is illustrated schematically.

[0038] like Figures 1 to 8 As shown, this application discloses an automatic reversing device, including: a conveyor belt 1, and a reversing device 3 and a gear speed regulating mechanism disposed on the conveyor belt 1. The conveyor belt 1 transports goods along a set direction. The reversing device 3 includes: an arc-shaped track 5 and a rotating lever (including a lever body 35, etc.). The arc-shaped track 5 and the conveyor belt 1 have two connection points, namely a front connection point and a rear connection point. The rotating lever rotates periodically. During the rotation, the goods on the conveyor belt 1 slide into the arc-shaped track 5 at the front connection point, and after sliding and reversing on the arc-shaped track 5, slide back to their original position on the conveyor belt 1 from the rear connection point. The gear speed regulating mechanism links the conveyor belt 1 and the rotating lever, matching the traveling speed of the conveyor belt 1 and the rotation speed of the rotating lever, so that when the rotating lever rotates to the rear connection point, the goods on the conveyor belt 1 have just moved to the rear connection point from their original position.

[0039] With the above structure, the automatic reversing device of this application utilizes the arc-shaped track 5, the rotating lever and the gear speed adjustment mechanism to realize the 180° reversal of the transported items on the conveyor belt 1, which can free up manpower and realize the automatic reversal of the transported items, such as realizing the automatic reversal of the bottle mouth and bottle bottom of the vial, thereby meeting the monitoring and packaging process requirements of glass bottle production.

[0040] The automatic reversing device of this application consists of an arc-shaped track 5, a rotating lever, and a gear speed regulation mechanism. Compared with complex electrically controlled robotic arms, it significantly reduces manufacturing and maintenance costs. Furthermore, since the glass bottles slide along the arc-shaped track 5, there is no risk of them falling and breaking, making the reversing process safer and more reliable. Therefore, the automatic reversing device of this application has the advantages of simple structure and principle, lower cost, high accuracy and safety, and can save manpower and improve production efficiency. Understandably, the automatic reversing device of this application can be used not only in the glass bottle production field but also in other production line processes requiring automatic reversing.

[0041] In some embodiments of this application, the conveyor belt 1 includes: drive teeth 12. For example... Figure 1 As shown, the transmission gear 12 can be positioned at the edge of the conveyor belt 1. The commutator 3 includes a transmission gear 31, which is coaxially connected to the rotating lever, driving the rotating lever to rotate coaxially. The gear speed control mechanism includes a speed control gear shaft 2, which includes an upper gear 21 and a lower gear 22 coaxially connected. The upper gear 21 meshes with the transmission gear 31 of the commutator 3, and the lower gear 22 meshes with the transmission gear 12 of the conveyor belt 1, thereby achieving linkage between the conveyor belt 1 and the rotating lever. By setting the dimensions of the upper gear 21 and the lower gear 22, the speed matching between the conveyor belt 1 and the rotating lever can be achieved, so that when the rotating lever moves the transport object from the front connection point to the rear connection point, the conveyor belt 1 travels exactly the distance between the front and rear connection points. That is, the space formed after the conveyor belt 1 moves away from the transport object moves exactly to the rear connection point, so that the rotating lever moves the transport object back to its original position on the conveyor belt 1 after reversing the direction.

[0042] In the embodiments of this application, such as Figure 3 As shown, the speed regulating gear shaft 2 includes a transmission inner shaft 23 and a fixed bushing 24. The transmission inner shaft 23 is rotatably mounted inside the fixed bushing 24, and the fixed bushing 24 is connected to the support column 6 to fix the transmission inner shaft 23. The upper gear 21 and the lower gear 22 are connected to the transmission inner shaft 23 and can rotate coaxially with the transmission inner shaft 23.

[0043] In some embodiments of this application, the radii of the commutator 3's rotating lever and the transmission gear 31 are the same, denoted as R / 2. The arc track 5 is a semi-circular ring, and the part connecting the conveyor belt 1 to the arc track 5 is straight. The radius ratio of the upper gear 21 and the lower gear 22 of the speed regulating gear shaft 2 is π / 2. Since the upper gear 21 and the lower gear 22 rotate coaxially and have the same angular velocity, their linear velocity ratio is also π / 2, thus the ratio of the distance traveled by the rotating lever to the distance traveled by the conveyor belt 1 is also π / 2. When the rotating lever moves from the front connection point to the rear connection point, the rotating lever's rotation distance is πR / 2. At this time, the conveyor belt 1 has traveled a distance of exactly R, so the transported item on the conveyor belt 1 has also reached the rear connection point from its original position. Thus, the transported item can be accurately reversed and transported back to its original position.

[0044] In other embodiments of this application, depending on the design of the travel distance of the conveyor belt 1 and the rotating lever, the radius ratio of the upper gear 21 and the lower gear 22 can also be set to other values, as long as the original position of the rotating lever and the transported object on the conveyor belt 1 arrives at the rear connection point simultaneously. For example, when a quarter-circle arc track 5 needs to be set on both sides of the right-angle corner of the conveyor belt 1 for spatial layout, the ratio of the upper gear 21 to the lower gear 22 can be set to π / 4 to achieve the above-mentioned speed matching requirements. The specific design can be adjusted by those skilled in the art according to actual conditions, and is not limited to the above-mentioned ratio values.

[0045] In this application Figures 1 to 9 In the illustrated embodiment, rotating the lever moves one transported item (i.e., glass bottle) at a time to change direction. Based on this, this embodiment uses multiple sets of matching reversing devices 3 and gear speed regulating mechanisms on the same conveyor belt 1 to achieve automatic reversing of all transported items. Figure 9 As shown.

[0046] Furthermore, in some embodiments of this application, the rotating lever can also be configured to simultaneously move multiple transport items, correspondingly, the arc-shaped tracks 5 are configured as multiple parallel tracks. Rotating the lever moves multiple transport items at once, causing them to slide along the multiple arc-shaped tracks 5 respectively, thus synchronously achieving reversal. This design allows multiple transport items to automatically reverse direction with a single rotation of the lever, improving the single-cycle reversal efficiency of the automatic reversing device and reducing the number of reversing devices required for all transport items to reverse direction. Understandably, when multiple transport items return to their original positions on the conveyor belt 1 after reversing, it means returning to the group of original positions corresponding to the multiple transport items, rather than the individual original positions corresponding to each transport item. For example, refer to... Figure 6 and Figure 8 As shown, at the front connection point, if the lever is rotated to simultaneously move the glass bottles at positions A, B, and C, then at the rear connection point, rotating the lever will move the three glass bottles into positions C, B, and A respectively.

[0047] In some embodiments of this application, reference is made to Figures 4 to 8 As shown, the rotary lever is a height-adjustable mechanism, including a height-adjustable lever body 35 and a height-adjustable knob 36 for driving the lever body 35. The lever body 35 includes a rack 351, and the height-adjustable knob 36 includes a height-adjustable gear 362 and a lever knob 361. The height-adjustable gear 362 meshes with the rack 351 of the lever body 35. By rotating the lever knob 361, the height of the lever body 35 can be easily controlled, allowing the lower end of the lever body 35 to contact or disengage from the glass bottle, thereby controlling the start or stop of the toggle reversal action. In this embodiment, the height-adjustable knob 36 is a cross knob with an easily movable cross lever.

[0048] In some embodiments of this application, such as Figures 6 to 8 As shown, the commutator 3 also includes a lowering lever 41 and an uppering lever 42. The lowering lever 41 is located at the front connection point, higher than the central axis of the lever knob 361, and the uppering lever 42 is located at the rear connection point, lower than the central axis of the lever knob 361. When the lever is rotated to the front connection point, the lowering lever 41 automatically contacts the lever knob 361, thereby rotating the lever knob 361 and driving the lever body 35 to descend to move the transported object. Figure 6 As shown. When the lever is rotated to the rear connection point, the rising lever 42 automatically contacts the lever knob 361, thereby rotating the lever knob 361 in the opposite direction and driving the lever body 35 to rise to detach from the transported object. Figure 8 As shown. Thus, the rotary lever of this application can automatically drive the lever body 35 to descend and rise when rotating, so that the entire automatic reversing device does not require manual intervention or electric drive, has a simple structure and low operating cost.

[0049] In some embodiments of this application, the commutator 3 further includes a circular housing 4, which covers the arc-shaped track 5 and the rotating lever. A descending lever 41 and a ascending lever 42 are both disposed on the inner wall of the circular housing 4. The circular housing 4 serves to assist in protecting the sliding of the glass bottle, preventing it from sliding off the arc-shaped track 5 and falling. Furthermore, the circular housing 4 also protects the internal structure.

[0050] In some embodiments of this application, the commutator 3 further includes: a rotating shaft 32, a rotating beam 33, and a fixed sleeve 34. The rotating shaft 32 passes through the circular outer shell 4 to connect to the transmission gear 31 and to the rotating beam 33. The fixed sleeve 34 is installed at the lower end of the rotating beam 33. The lever body 35 is vertically and slidably embedded in the fixed sleeve 34. The fixed sleeve 34 and the lever body 35 slide with damping. When the lifting knob 36 is not activated, the lever body 35 will not slide down due to gravity.

[0051] In some embodiments of this application, the conveyor belt 1 includes a groove 11, which is a placement position for transported items. The arc-shaped track 5 is provided with a groove, the cross-sectional shape and size of which are consistent with the groove 11, so that it can be aligned and docked with the groove 11 of the conveyor belt 1, facilitating the sliding in and out of glass bottles.

[0052] In some embodiments of this application, such as Figure 1 As shown, the automatic commutation device also includes a support column 6, and the commutator 3 and the gear speed regulating mechanism are both fixed on the support column 6. Specifically, in this embodiment, the circular outer shell 4 of the commutator 3 is fixedly connected to the support column 6, and the fixed bushing 24 of the speed regulating gear shaft 2 is fixedly connected to the support column 6.

[0053] This application also discloses an automatic reversing transport system, including the automatic reversing device shown in the above embodiment, which has the beneficial effect of realizing automatic reversing of transported goods at low cost. In a preferred embodiment, the conveyor belt 1 of the automatic reversing device is provided with multiple sets of matching reversing devices 3 and gear speed regulating mechanisms, which can realize the automatic reversing of all transported goods on the conveyor belt 1.

[0054] Combination Figures 1 to 9 The following diagram illustrates the working principle of the automatic commutation device embodiment of this application:

[0055] like Figure 6 As shown, at the front connection point, when the commutator 3's rotation lever passes the descending paddle 41, the cross-shaped lever knob 361 is activated, and the lifting gear 362 rotates and engages the rack 351, causing the lever body 35 to descend. The lowest point of the lever body 35 descends from a position slightly above the transported object in the groove 11 to the center height of the transported object. Thus, the lever body 35 begins to push one end of the transported object to move along the arc-shaped track 5 within the groove 11. Specifically, the descending paddle 41 is installed inside the circular housing 4, positioned slightly above the rotational center axis of the lever knob 361. When the lever knob 361 passes the descending paddle 41, the cross bar of the lever knob 361 rotates under the obstruction of the descending paddle 41. The rotation of the lever knob 361 causes the lifting knob 36 to rotate around its central axis. The lifting gear 362 of the lifting knob 36 engages and rotates with the rack 351 on the lever body 35, driving the lever body 35 to descend. After passing through one lowering lever 41, the lifting knob 36 rotates 90 degrees; after passing through two lowering levers 41, the lifting knob 36 rotates 180 degrees, thereby lowering the lever body 35 to the appropriate position.

[0056] like Figure 7As shown, under the meshing action of the speed regulating gear shaft 2, the lower gear 22 meshes with the transmission gear 12 of the conveyor belt 1, and the upper gear 21 meshes with the transmission gear 31 of the commutator 3. As the conveyor belt 1 moves, the speed regulating gear shaft 2 transmits power to the commutator 3, driving the rotation lever of the commutator 3 to rotate. The lever body 35 pushes the transported object to move on the arc track 5, so that the transported object leaves the groove 11 and returns to the original groove 11 at the same time, achieving a 180° rotation reversal.

[0057] The process of transporting goods returning to conveyor belt 1 is as follows: Figure 8 As shown, at the rear connection point, the rotation lever of the commutator 3 rotates past the rising lever 42, and the cross-shaped lever knob 361 is reversed. The lifting gear 362 rotates and meshes with the rack 351, causing the lever body 35 to rise. At this time, the transported item is pushed back to the original groove 11 on the conveyor belt 1. Then, the lever body 35 continues to rise, leaving the transported item, and the pushing process stops. Thus, the transported item has completed automatic reversal and can continue to move along the conveyor belt 1 to the next process. Specifically, the rising lever 42 is installed inside the circular housing 4, positioned slightly below the rotation center axis of the lever knob 361. When the lifting knob 36 passes the rising lever 42, the cross lever of the lever knob 361 rotates under the obstruction of the rising lever 42, causing the lifting knob 36 to rotate around the central axis. The lifting gear 362 of the lifting knob 36 meshes with the rack 351 on the lever body 35 and rotates, driving the lever body 35 to rise. After passing one rising lever 42, the lifting knob 36 rotates 90 degrees. After passing two rising levers 42, the lifting knob 36 rotates 180 degrees, raising the lever body 35 to the appropriate position to detach it from the transported object. Then, rotating the lever will continue to rotate until it returns to the front connection point, starting the next round of toggle reversal.

[0058] In this embodiment, since the commutator 3 performs a single-item reversal at a time, therefore, as Figure 9 As shown, multiple sets of matching reversing devices 3 and gear speed regulating mechanisms can be installed on a conveyor belt 1 to achieve automatic reversing of all transported items on the conveyor belt 1. For example, from... Figure 9 As can be seen, there are seven grooves 11 between the two connection points of the arc track 5 and the conveyor belt 1. That is, when the commutator 3 rotates half a turn to change the direction of one transported object, six transported objects will pass by without contacting the rotating lever (i.e., without changing direction). Each time the commutator 3 changes direction, the rotating lever needs to rotate one full turn. Thus, twelve sets of commutators 3 and speed regulating gear shafts 2 can be continuously set to realize the automatic changing of all transported objects.

[0059] In some other preferred embodiments of this application, to improve reversing efficiency, multiple arc-shaped tracks 5 of the automatic reversing device can be provided, correspondingly, rotating the lever simultaneously moves multiple transported items. For example, the rectangular area at the lower end of the lever body 35 can be made wider to move multiple transported items at once. Based on this, if a reversing device 3 is provided with two arc-shaped tracks 5, rotating the lever once will simultaneously reverse two transported items, then only six sets of reversing devices 3 and speed-regulating gear shafts 2 are needed to complete all reversing on a conveyor belt 1; if a reversing device 3 is provided with three arc-shaped tracks 5, rotating the lever once will simultaneously reverse three transported items, then only four sets of reversing devices 3 and speed-regulating gear shafts 2 are needed to complete all reversing on a conveyor belt 1, and so on.

[0060] In summary, the automatic reversing device of this application includes a conveyor belt, a reversing mechanism, and a gear speed regulating mechanism. The reversing mechanism includes an arc-shaped track and a rotating lever. The rotating lever is used to move the transported object along the arc-shaped track, which provides a sliding turning point for the transported object. The gear speed regulating mechanism matches the travel speed of the conveyor belt with the rotation speed of the rotating lever, so that the rotating lever returns the transported object to its original position on the conveyor belt after reversing its direction. This application achieves 180° reversal of the transported object on the conveyor belt through the arc-shaped track, rotating lever, and gear speed regulating mechanism. It features a simple structure, lower cost, high accuracy and safety, and can save manpower and improve production efficiency.

[0061] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
