Description

Technical Field

[0001] The present invention relates to a turning mechanism and a turning method used in packaging automation equipment, and in particular to a turning mechanism and a turning method in the field of bottle filling assembly line equipment. The bottle generally refers to containers such as bottles, cans, and cups. Background Art

[0002] For most bottle filling line equipment, if you need to change to another bottle, all parts related to the bottle size need to be replaced, including the bottle separation screw, all star wheels and all related parts that limit the bottle and protect the bottle). The replacement is troublesome, time-consuming and labor-intensive.

[0003] Some bottle filling lines can transport bottle trays, but only regular transportation can be achieved. Once there is a need to flip the bottle trays on the line, such as in the drying, cleaning and other links, it is difficult to handle and it is difficult to use the bottle trays.

[0004] In the past, for the flipping of bottles, a robot was used to directly clamp the bottle mouth and flip it. For light-weight bottles, when it comes to the next process, it can only be transported by clamping the bottle mouth. When the next process is filling, there must be a structure to fix the bottle so that it can be filled without clamping the bottle mouth. These bottle parts need to be replaced when the bottle specifications are changed. For large and heavy bottles, there are also guardrails and bottom support structures for the bottles, but when changing to another type of bottle, these auxiliary structures also need to be replaced together, which is also troublesome, time-consuming and labor-intensive. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a flipping mechanism that can flip the bottle holder at the same time. To this end, the present invention adopts the following technical solutions:

[0006] The flip mechanism comprises a connecting structure with a rotating connecting mechanism inside and a first mechanism connected to the bottle, the connecting structure has a structure that cooperates with the flip control mechanism, and the first mechanism is connected to the connecting structure; it is characterized in that the flip mechanism is also provided with a bottle holder, the bottle holder is a limiting container for the bottle, the flip mechanism has a bottle holder space and a bottle holder anti-falling mechanism adapted to the bottle holder space, the bottle holder anti-falling mechanism is connected to the connecting structure, and the first mechanism corresponds to the bottle portion exposed above the bottle holder.

[0007] On the basis of adopting the above technical solutions, the present invention may also adopt the following further technical solutions, or use these further technical solutions in combination:

[0008] The bottle tray anti-falling mechanism has a bottle tray supporting structure and a bottle tray supporting structure, and the bottle tray anti-falling mechanism has an opening for the bottle tray to enter and leave the turning mechanism.

[0011] The structure of the bottle support is matched with the position above the middle of the bottle support, and a structure for supporting the bottle is further provided below the structure of the bottle support; or, the structure of the bottle support is matched with the position above the middle of the bottle support, and a structure for supporting the bottle is further provided above the structure of the bottle support.

[0012] The structure of the bottle support includes two claws that can be rotated to open and reset to close, the two claws clamp the bottle support from both sides, the structure of the bottle support also has a supporting structure for the bottle support on the inner side, the bottle support has a clamping groove that cooperates with the claws, and an open mouth with a changeable size is provided between the heads of the two claws for the bottle support to enter the flip mechanism, clamp the bottle support, and the bottle support to detach from the flip mechanism.

[0013] The turning mechanism is composed of a first mechanism at the top, a bottle supporting structure at the middle, and a bottle supporting structure at the bottom to form a connecting structure for a combination of the bottle and the bottle support.

[0019] The second object of the present invention is to provide a flipping method to improve efficiency. To this end, the present invention adopts the following technical solutions:

[0020] The flipping method uses a flippable mechanism that is connected to the bottle and also accommodates the bottle tray and prevents the bottle tray from falling. When the bottle flips, the bottle tray is also flipped and then flipped back together. In the subsequent transportation, the bottle is still placed in the bottle tray for transportation.

[0021] The present invention, for the flipping of the bottle, connects and limits the bottle holder and the bottle as a combination on the basis of connecting the bottle, thereby solving the technical problem of not needing to dismantle and replace equipment parts when replacing bottles in a filling line that requires flipping of the bottles.

[0028] Referring to the accompanying drawings, the flip mechanism provided by the present invention includes a connection structure with a rotating connection mechanism inside. The connection structure includes a component 11 that cooperates with the flip control mechanism 100 and a component 12 connected to the conveying device. The component 11 is rotatably connected in the connection structure, and its axis is the flip axis of the flip mechanism. The first mechanism connected to the bottle and the bottle tray anti-fall mechanism in the flip mechanism are connected to the component 11, and are synchronously flipped with the rotation of the component 11, and the combination of the bottle 200 and the bottle tray 300 is flipped up and down. The flip control mechanism 100 can be a guide rod around the motion track of the flip mechanism.

[0029] The flip mechanism is provided with a first mechanism connected to the bottle, and the bottle portion corresponding to the mechanism exposed on the bottle holder can be a clamp mechanism 2, which clamps the bottle mouth or neck of the bottle 200. The opening and closing of the clamp mechanism 2 is controlled by the roller 21 at its rear and the control component on the machine. When the flip mechanism moves to the position where the control component is located, the control component pushes the roller 21 to open the clamp mechanism. After the roller 21 passes through the control component, the control component loses its support, and the clamp mechanism 2 is reset by the drive of its elastic component, so that the clamp mechanism 2 clamps the bottle mouth or neck.

[0030] The flipping mechanism has a bottle holder space 305 and a bottle holder anti-falling mechanism adapted to the bottle holder space 305. The bottle holder anti-falling mechanism preferably has a bottle holder supporting structure, a bottle holder supporting structure, and an open opening for the bottle holder to enter and leave the flipping mechanism. For the flipping of the bottle, the bottle holder can be supported and supported on the basis of being connected to form a bottle holder and bottle combined flipping body.

[0031] More preferably, the bottle support structure is engaged with the bottle support 300, the bottle support structure is engaged with the position above the middle of the bottle support, and a bottle support structure is provided below the bottle support structure. Furthermore, the flip mechanism is composed of the first mechanism at the top, the bottle support structure at the middle, and the bottle support structure at the bottom to form a connection structure for the combination of the bottle and the bottle support. In this way, the structure is simple, and the bottle support and the bottle are reliably connected, and can adapt to flipping of various actions.

[0032] As for the snap-fitting, the structure of the bottle holder may include two claws 41 that can be rotated to open and reset, the two claws 41 clamp the bottle holder 300 from both sides, and exert an upward force on the bottle holder, and there is an open opening 43 of variable size between the heads of the two claws 41 for the bottle holder 300 to enter and leave the flip mechanism, and the claws 41 clamp the bottle holder 300. The two claws 41 may be connected to springs, and when the bottle holder 300 enters the flip mechanism, the bottle holder pushes the claws open and enters the open opening 43, and when the bottle holder 300 leaves the flip mechanism, it is dragged by the mechanical connection mechanism to push the claws open and leave the flip mechanism.

[0033] The structure of the bottle holder also has a supporting structure 42 for the bottle holder, and the structure 42 can be a structure such as the transverse root of the clamping claw, the arc-shaped part of the clamping claw, etc., which can play the role of supporting the bottle holder from the side. The clamping claw 41 clamps the bottle holder from the side of the bottle holder, and itself has the function of supporting the bottle from both sides, playing the role of the supporting structure 42. When the clamping claw clamps the bottle holder, the supporting structure 42 can prevent the bottle holder from shifting and becoming unstable, thereby improving the limiting effect.

[0034] The side wall of the bottle holder 300 has a clamping groove 306 that cooperates with the clamping claw 41 .

[0035] The structure of the bottle support has a structure of supporting the bottle 300 from the inside and both sides. It can be a fixed structure or a movable structure like the aforementioned claws, but a fixed structure is simpler and more preferred. It can be two curved handrails 51 on the left and right, and the open mouth 52 on the outside is for the bottle support to enter and leave the flip mechanism.

[0036] The flip mechanism is provided with a bottle holder 300, which is a limiting container for the bottle. The bottle holder 300 includes a cavity 301 adapted to a bottle of a specific shape, a side wall 302 surrounding the cavity 301 to position the bottle and capable of cooperating with the second mechanism, and a cavity bottom wall 303 adapted to the conveying bearing surface; the cavity 301 has a bottle insertion and removal port 304, and the shape of the bottle holder 300 matches the conveying size standard of the conveying device and the matching requirements of the mechanical connection structure in the conveying device. For bottles of different shapes, there are different types of bottle holders 300, but different bottle holders have consistent shapes to match the conveying size standard of the conveying device and the matching requirements of the mechanical connection structure in the conveying device, except that the size and shape of the cavity 301 inside them are different to adapt to the specific shapes of different types of bottles, and the size standard can be a fixed distance standard, a width standard, a length standard, etc. The cavity bottom wall 303 can be placed stably on the conveying bearing surface and can slide stably on the conveying bearing surface when needed. It can be a flat surface or a concave-convex surface. The conveying bearing surface can be a circulating conveying surface, such as a conveyor belt, chain plate, etc., or it can be a fixed conveying bearing surface, such as a table top. The position of the bottle holder is adjusted and the next workstation is entered by sliding the bottle holder. One or more rows can be formed, and the spacing between the bottles is located by the outer dimensions of the bottle holder.

[0037] As mentioned above, the bottle holder anti-drop mechanism of the bottle holder may also be composed of a structure that has both a support and a support. Alternatively, the bottle holder anti-drop mechanism of the bottle holder may also be composed of a support structure and a structure that is inserted into or passes through the bottle holder, or a support structure and a structure that is inserted into or passes through the bottle holder, so that when the bottle holder is facing upward, an upward force is applied to stabilize and position the bottle, and during the turning process, the bottle holder can be supported from the side and blocked at the bottom by the bottle connected to the first mechanism.

[0038] Depend on Figure 1 As can be seen from the above description, the flipping method provided by the present invention uses a flippable mechanism that is not only connected to the bottle, but also accommodates the bottle tray and prevents the bottle tray from falling. When the bottle is flipped, the bottle tray is also flipped together, and then flipped back together. In the subsequent transportation, the bottle is still placed in the bottle tray for transportation.

[0039] The turnover mechanism provided by the present invention can be applied to a filling production line as a turnover mechanism in a conveying device with turnover conveying function.

[0040] by Figure 5For example, in the conveying device of the filling assembly line, it includes a fixed-distance conveying device 401, a disinfectant spraying section conveying device 402, a drying section conveying device 403, and an output section conveying device 404. The drying section conveying device 403 adopts the above-mentioned flipping mechanism to be connected with the bottle and bottle holder combination; along the conveying path, from the fixed-distance conveying device 401 to the output section conveying device 404, a mechanical connection structure that cooperates with the bottle holder is provided, and the shape of the bottle holder 300 matches the conveying size standard and width requirements of the conveying device and the matching requirements of the mechanical connection structure in the conveying device.

[0041] The fixed-distance conveying device 401 adopts a screw conveying device as a mechanical connection structure that cooperates with the bottle holder to fix the distance of the bottle holder, and the pitch of the screw 4010 matches the size of the bottle holder 300; the disinfectant spraying section conveying device 402 adopts a rotating star wheel, and the concave section 4020 on the rotating star wheel serves as the mechanical connection structure of the disinfectant spraying section conveying device connected to the bottle holder, and the bottle holder 300 can just fit into the concave section 4020; the drying section conveying device adopts a rotating wheel 4030, and the flipping mechanism is arranged on the rotating wheel 4030 with equal arc length, and the component 12 in the flipping mechanism is connected to the rotating wheel 4030; the output section conveying device 404 adopts a rotating star wheel, and the concave section 4040 on the rotating star wheel serves as the mechanical connection structure of the output section conveying device connected to the bottle holder, and the bottle holder 300 can just fit into the concave section 4040.

[0042] by Figure 6 For example, in the conveying device of the filling assembly line, it includes a fixed-distance conveying device 501, a disinfectant spraying section conveying device 502, a drying section conveying device 503, and a filling section conveying device 504. The drying section conveying device 503 adopts the above-mentioned flipping mechanism to be connected with the bottle and bottle holder combination; along the conveying path, from the fixed-distance conveying device 501 to the filling section conveying device 504, a mechanical connection structure that cooperates with the bottle holder is provided, and the shape of the bottle holder matches the conveying size standard and width requirements of the conveying device and the matching requirements of the mechanical connection structure in the conveying device.

[0043] The fixed-distance conveying device 501 adopts a screw conveying device as a mechanical connection structure that cooperates with the bottle holder to fix the distance of the bottle holder, and the pitch of the screw 5010 matches the size of the bottle holder 300; the disinfectant spraying section conveying device 502 adopts a rotating star wheel, and the concave section 5020 on the rotating star wheel serves as a mechanical connection structure of the disinfectant spraying section conveying device connected to the bottle holder, and the bottle holder 300 can just fit into the concave section 5020; the drying section conveying device adopts a rotating wheel 5030, and the turning mechanism is set on the rotating wheel 5030 with equal arc length, and the component 12 in the turning mechanism is connected to the rotating wheel 5030; the filling section conveying device 504 adopts a rotating star wheel, and the concave section 5040 on the rotating star wheel serves as a mechanical connection structure of the output section conveying device connected to the bottle holder, and the bottle holder 300 can just fit into the concave section 5040. Reference numeral 505 denotes an output conveying device after the filling section. Bottles filled and capped in the filling section together with bottle trays are transferred to the output conveying device 505 . The conveyor belt width of the output conveying device 505 is adapted to the width of the bottle tray.

[0044] The turning structure and the conveying device with turning and conveying function of the present invention can also be applied to other filling lines, for example, a filling line with a cleaning section and a cleaning section conveying device. There can be more than one station for turning between the fixed distance conveying device and the output section conveying device or the filling section conveying device.

[0045] It can be seen that the flipping structure and the conveying device with flipping conveying of the present invention can be applied to various filling lines to realize a bottle and tray combined conveying method that is configured with flipping all the way to the bottom. After the bottle enters the filling line, the bottle is placed in the bottle tray for conveying from the distance station to the bottle output station; during translational conveying, the bottle tray is distanced with the conveying device or connected to the mechanical connection structure in the conveying device. Before the bottle output station, at least one station section flips the bottle, and a flippable mechanism is used to connect with the bottle and also to support and hold the bottle tray. When the bottle flips, the bottle tray is also flipped together and flipped back. In the subsequent conveying, before the bottle is output, the bottle is still placed in the bottle tray for conveying. During translational conveying, the bottle tray is distanced with the conveying device or connected to the mechanical connection structure in the conveying device. In this way, when replacing the bottle, in addition to replacing the bottle tray, there is no need to replace other parts in the mechanical equipment related to the bottle type, which greatly improves efficiency.

[0046] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the protection scope of the present invention.
