Description

Technical Field

[0001] This invention relates to the field of container conveying, and in particular to a tilting device for inclined containers. Background Technology

[0002] Existing containers, such as bottles, boxes, and cans, have two types of openings when their bottoms are aligned horizontally with the ground: one is a vertically upward orientation, and the other is an inclined orientation. Existing equipment for processing containers through various processes (e.g., cleaning, filling, capping, screwing caps) typically employs a linear motion in a vertical direction relative to the container opening to complete the corresponding processing steps for containers with the first type of opening distribution. For containers with the second type of opening distribution, there are usually two solutions. One is to set up a material support unit and place the container on the material support unit so that the opening of the container is kept vertically upward, thereby completing the processing. However, this will add material support units and equipment for placing and removing containers to the production line for processing the container, which will increase the manufacturing cost of the supply-side manufacturing enterprise and the purchase cost of the demand-side buyer, and at the same time increase the labor cost of both parties. Another solution is to add tilt angle adjustment components to the processing units of the equipment that handles container processing (e.g., filling heads, washing heads). This allows for changing the tilt angle and coordinating with the tilted containers conveyed on the conveyor line. However, since the tilt angle varies between batches of containers with different openings, adjusting the tilt angle of the processing unit often wastes a lot of time, reducing production efficiency. Furthermore, since most bottle openings are vertically upward, this type of processing unit is often difficult to adapt to different production environments. In addition, existing capping and screwing capping equipment typically grips the caps horizontally, while the processing unit maintains a tilted posture to complete the various processes (cap gripping, screwing, and follow-up capping), significantly increasing control and manufacturing costs, which is detrimental to the product's competitive advantage in the market.

[0003] In summary, how to flip a slanted container and adjust its opening to face upwards has become an urgent problem for researchers in this field. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to flip a slanted container so that the opening of the slanted container is facing upwards; To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention is a tilting container device for tilting containers conveyed on a conveying assembly, comprising: A clamping assembly, connected to a conveying assembly, is used to clamp and limit the position of a vertical container; A flipping component, which is connected to a conveying component, is used to switch the container to a vertical or tilted position as the conveying component moves after the container is clamped and limited. When the container is in a tilted position, the opening of the container faces upward.

[0005] Furthermore, when the container is conveyed along an arc-shaped trajectory, the clamping assembly includes: a workstation tray, which is horizontally rotatably positioned above the conveying assembly, and the outer peripheral wall of the workstation tray has multiple clamping openings extending inward; an arc-shaped guardrail is provided on the outer side of the workstation tray. The container is clamped and limited between the arc-shaped guardrail and the clamping opening, and moves as the workstation panel rotates.

[0006] Furthermore, the workstation tray is configured as an upper workstation tray and a lower workstation tray, which are connected by a fixing rod; the clamping port of the upper workstation tray is configured as an upper clamping port, which cooperates with the arc-shaped guardrail to clamp and limit the middle part of the container; the clamping port of the lower workstation tray is configured as a lower clamping port, which cooperates with the arc-shaped guardrail to clamp and limit the bottom of the container.

[0007] Furthermore, the width of the upper clamping opening and the lower clamping opening is greater than the outer diameter of the container, and the inner walls of the upper clamping opening and the lower clamping opening are the contact surfaces; when the container is tilted and located inside the clamping opening, the contact surfaces are in contact with the outer wall of the container.

[0008] Furthermore, the flipping assembly includes: a flipping clamp, a plurality of which are rotatably disposed on the top of the workstation plate and corresponding to the clamping opening, the flipping clamp having an outward flipping opening; a guide plate is fixedly disposed on the top of the workstation plate, the bottom of the guide plate having a closed-loop guide groove, and a guide rod located in the guide groove is fixed on the flipping clamp; the top of the container is located within the flipping opening, and the flipping clamp, as the workstation plate moves and guided by the guide groove, independently rotates on the top of the workstation plate and contacts the top of the container, forcing the container to switch between a vertical and tilted posture during the process of the container moving in an arc trajectory.

[0009] Furthermore, the guide groove is distributed as a concentric section, a gradually separating section, and a gradually approaching section connected end to end in sequence. The center of the concentric section is set concentrically with the center of the guide disk. The distance from the gradually separating section to the center of the guide disk gradually increases, and the distance from the gradually approaching section to the center of the guide disk gradually decreases.

[0010] Furthermore, a working disc rotatably mounted on the conveying assembly is provided on one side of the clamping assembly. The outer peripheral wall of the working disc has multiple working openings inward. An arc-shaped guide rail is fixed to the outer side of the working disc, and the guide end of the guide rail can act on the side wall of the container. The working disc and the guide rail are staggered in the height direction of the work station plate, and the rotation direction of the working disc is opposite to the rotation direction of the work station plate. The flipping assembly guides the container, which has been flipped to an inclined position, into the gap between the working opening and the guide rail through the guide end.

[0011] Furthermore, the inner wall of the working port is an inclined surface that conforms to the outer wall of the inclined container.

[0012] Furthermore, when the container is conveyed along a straight trajectory, the conveying assembly includes: an input line, a processing line, and an output line connected in sequence; guardrails are provided on the input line and the output line; the clamping assembly on the processing line includes a clamping block that can move relative to and clamp the container; and the processing line is flipped by the flipping assembly. The connection points between the input line and the processing line, as well as the connection points between the processing line and the output line, are equipped with baffles that can move perpendicular to the conveying direction.

[0013] Furthermore, the flipping assembly includes a cylinder, with one side of the processing line hinged to it, and the output end of the cylinder connected to the opposite side. When the cylinder operates, it drives the processing line to rotate around the hinge point.

[0014] The beneficial effects of the present invention are as follows: The present invention is a tilting container tilting device. The device realizes the conveying of the container through the conveying component. During the conveying process, the container is stably conveyed through the clamping component. The tilting component tilts the container after clamping and limiting it, and adjusts the container to a state with the mouth facing upward. At this time, the container is cleaned, filled, capped and screwed on. After the container process is completed, the bottle is guided to a state with the bottle body vertical and the mouth tilted, which facilitates the continued transportation of the container.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] See Figure 1 The diagram shows the structure of the slanted container 01. When the body of the container 01 is in a vertical position, the mouth 02 is in a slanted position. In order to adjust the mouth 02 to a vertical upward position to facilitate the cleaning, filling, capping, and screwing processes of the container, the body 03 needs to be adjusted to a slanted position. In order to adjust the bottle body 03 to a tilted position, the present invention discloses Embodiment 1 and Embodiment 2, as follows: Example 1 See Figure 2This embodiment is a tilting container flipping device, including a conveying component 1, a clamping component 2, and a flipping component 3. The conveying component 1 is a base, and the container 01 is in frictional contact with the conveying component 1. The clamping component 2 is disposed on the conveying component 1, and the flipping component 3 is disposed on the clamping component 2. The clamping component 2 is used to clamp and limit the container 01 and drive the container 01 to move in an arc-shaped trajectory. The flipping component 3 is used to flip the container 01 after clamping and limiting it. For example, while the clamping component 2 rotates clockwise, the flipping component 3 rotates counterclockwise. That is, while the container 01 moves in an arc-shaped trajectory, the container 01 itself can also be flipped, flipping the container 01 into a tilted state with the opening 02 facing upward.

[0020] See Figure 3 In some possible embodiments, to illustrate the specific structure of the clamping component 2, this embodiment uses a workstation tray 21. The workstation tray 21 is horizontally rotatably positioned above the conveying component 1. A motor is located at the center of the workstation tray 21, driving the workstation tray 21 to rotate clockwise. The outer peripheral wall of the workstation tray 21 has multiple clamping openings 22. An arc-shaped guardrail 23 is provided on the outer side of the workstation tray 21. The container 01 is clamped and limited between the arc-shaped guardrail 23 and the clamping openings 22, and the container 01 moves clockwise as the workstation tray 21 rotates. In this embodiment, the container 01 is placed vertically on the conveying assembly 1 and located inside the clamping port 22. As the workstation plate 21 rotates clockwise, the container 01 is driven to the inside of the arc-shaped guardrail 23 and moves along the arc-shaped trajectory inside the arc-shaped guardrail 23. The arc-shaped guardrail 23 prevents the container 01 from being thrown out of the clamping port 22.

[0021] See Figure 3 In some possible embodiments, to illustrate the specific structure of the workstation tray, this embodiment uses a workstation tray 21 configured as an upper workstation tray 211 and a lower workstation tray 212. The upper workstation tray 211 and the lower workstation tray 212 are arranged vertically and rotate synchronously. The upper workstation tray 211 and the lower workstation tray 212 are connected by multiple vertical fixing rods 213. The clamping port 22 of the upper workstation tray 211 is configured as an upper clamping port 221, which cooperates with the arc-shaped guardrail 23 to clamp and limit the middle part of the container 01. The clamping port 22 of the lower workstation tray 212 is configured as a lower clamping port 222, which cooperates with the arc-shaped guardrail 23 to clamp and limit the bottom of the container 01. The upper clamping port 221 and the lower clamping port 222 are correspondingly arranged. In this embodiment, two workstations are provided, an upper and a lower one. The upper clamping port 221 of the upper workstation 211 acts on the middle of the outer wall of the container 01, and the lower clamping port 222 of the lower workstation 212 acts on the bottom of the outer wall of the container 01. This arrangement ensures that the container 01 can move synchronously with the rotation of the workstation 21. If only one workstation 21 is provided, the container will tip over during the process of moving with the rotation of the workstation 21, making it impossible to perform subsequent filling and other processes.

[0022] See Figure 3 In some possible embodiments, to illustrate the specific structure of the upper clamping port 221 and the lower clamping port 222, this embodiment adopts an upper clamping port 221 and a lower clamping port 222 with a width greater than the outer diameter of the container 01. This setting facilitates the container 01 entering the clamping port 22 and also provides redundant space for the subsequent flipping of the container 01. The inner walls of the upper clamping port 221 and the lower clamping port 222 are fitting surfaces 223. When the container 01 is tilted and located in the clamping port 22, the fitting surfaces 223 fit against the outer wall of the container 01. Specifically, the left and right sides of the fitting surfaces 223 are inclined surfaces that gradually slope from top to bottom to the left. In this way, the container 01 can be tilted to the right and placed in the clamping port 22. At this time, the bottom left side of the container 01 is in point contact with the conveying component 1 (base), ensuring the stable conveying of the container 01.

[0023] See Figure 4 , 5 6. In some possible embodiments, to illustrate the specific structure of the flipping component 3, this embodiment adopts a flipping clamp 31, with multiple flipping clamps 31 rotatably disposed on the top of the workstation plate 21. The number and position of the flipping clamps 31 correspond to the clamping opening 22. Each flipping clamp 31 has an outward flipping opening 32. A guide plate 33 is fixedly disposed on the top of the workstation plate 21. The guide plate 33 is fixedly suspended above the workstation plate 21 by a connecting rod at the top. A closed-loop guide groove 34 is opened at the bottom of the guide plate 33. A guide rod 35 located in the guide groove 34 is fixed on the flipping clamp 31. The top of the container 01 is located in the flipping opening 32. As the workstation plate 21 moves and is guided by the guide groove 34, the flipping clamp 31 rotates independently on the bottom of the workstation plate 21 and contacts the top of the container 01. During the process of the container 01 moving in an arc trajectory, it is forced to switch between a vertical and tilted posture. In this embodiment, a flip clamp 31 is rotatably mounted on the top of the workstation tray 21. Specifically, the left side of the flip clamp 31 is movably connected to the workstation tray 21, and the right side of the flip clamp 31 is provided with a guide rod 35, which is located within a guide groove 34. During the rotation of the flip clamp 31 along with the workstation tray 21, the guide rod 35 engages with the guide groove 34, and the flip clamp 31 itself rotates. The top of the container 01 is located within the flip opening 32 of the flip clamp 31. As the workstation tray 21 rotates clockwise, the flip clamp 31 rotates relative to the top of the container 01. The workstation tray 21 first rotates counterclockwise, and the left side wall of the flipping port 32 contacts the top of the container 01, flipping the container 01 to the right. When it is tilted and guided into the subsequent work tray 41, the flipping clamp 31 first rotates clockwise relative to the workstation tray 21 to reset, adjusting the flipping port 32 to correspond with the clamping port 22, so as to facilitate the entry of the next container 01. Therefore, through the cooperation of the guide rod 35 and the guide groove 34, the flipping clamp 31 can rotate independently of the workstation tray 21, thereby realizing the switching of the container 01's posture.

[0024] See Figure 7 In some possible embodiments, in order to illustrate the specific structure of the guide groove 34, this embodiment adopts the guide groove 34 as a concentric segment 34a, a gradually separating segment 34b, and a gradually approaching segment 34c connected end to end in sequence. The center of the concentric segment 34a is set concentrically with the center of the guide disk 33. The distance from the gradually separating segment 34b to the center of the guide disk 33 gradually increases, and the distance from the gradually approaching segment 34c to the center of the guide disk 33 gradually decreases. In this embodiment, when the guide rod 35 is located within the concentric section 34a, the flipping opening 32 and the clamping opening 22 are vertically aligned, facilitating the entry of the container 01. At this time, the flipping opening 32 is located at the top of the container 01, the upper clamping opening 221 is located in the middle of the container 01, and the lower clamping opening 222 is located at the bottom of the container 01. When the guide rod 35 is located in the gradually moving section 34b, the flipping clamp 31 rotates counterclockwise relative to the workstation 21, gradually adjusting the container 01 to a state where the top of the container 01 is tilted to the right. When the guide rod 35 is located at the farthest end of the gradually moving section 34b, the container 01 is adjusted to the extreme state of tilting with the opening 02 facing upwards, which can be introduced into the subsequent work tray 41. When the guide rod 35 is located in the approach section 34c, the flipping clamp 31 rotates clockwise relative to the workstation 21. When the guide rod 35 is located at the closest end of the gradually moving section 34c, the flipping clamp 31 rotates to adjust the flipping opening 32 and the clamping opening 22 to be vertically aligned.

[0025] See Figure 8 , 910. In some possible embodiments, a working disc 41 rotatably located on the conveying assembly 1 is also provided on one side of the clamping assembly 2. The outer peripheral wall of the working disc 41 has multiple working openings 42. An arc-shaped guide rail 43 is fixed on the outer side of the working disc. The guide end 44 of the guide rail 43 can act on the side wall of the container 01. The working disc 41 and the guide rail 43 are staggered in the height direction of the station plate 21. The rotation direction of the working disc 41 is opposite to the rotation direction of the station plate 21. The flipping assembly 3 guides the container 01, which has been flipped to an inclined position, into the gap between the working openings 42 and the guide rail 43 through the guide end 44. In this embodiment, the working disc 41 is also divided into upper and lower layers. Each layer of the working disc 41 has a working port 42. When the guide rod 35 moves to the farthest end of the gradually separating section 34b, the container 01 is located at the inlet end 44 of the inlet guardrail 43 and the corresponding clamping port 22. At this time, the working port 42 and the corresponding clamping port 22 are staggered vertically. The container 01 is introduced into the working port 42 from the clamping port 22, and moves along the arc trajectory of the working disc 41 as it rotates along the gap between the working port 42 and the inlet guardrail 43. At this time, the container 01 is in the state with the mouth 02 facing upward, which facilitates the cleaning, filling, capping and screwing capping processes of the mouth 02.

[0026] See Figure 9 In some possible embodiments, the inner wall of the working port 42 is an inclined surface 45 that fits the outer wall of the inclined container 01. In this embodiment, the inclined surface 45 and the mating surface 223 have the same function, ensuring that the container 01 is stably and inclinedly located inside the working port 42.

[0027] It should be noted that the other side of the work tray 41 is also equipped with a clamping component 2 and a flipping component 3. The function of both is to adjust the tilted container 01 inside the work tray 41 from the tilted position to the vertical position.

[0028] Example 2

[0029] See Figure 11 , 12This embodiment is a tilting container tilting device for conveying a tilted container 01 along a straight trajectory. It includes: an input line 11, a processing line 12, and an output line 13 connected in sequence; guardrails 5 are provided on the input line 11 and the output line 13, and the function of the guardrails 5 is to regulate multiple containers and guide and adjust the container 01 to a uniform state; the conveying component 1 is used to drive the container to move; the processing line 12 is provided with a clamping block 6 that can move relative to and clamp the container 01; the processing line 12 is tilted under the drive of the tilting component 3. The connection points of the input line 11 and the processing line 12, as well as the connection points of the processing line 12 and the output line 13, are equipped with baffles that can move perpendicular to the conveying direction. The baffles are connected to cylinders. When the baffles extend, they can guide a rated number of containers into the processing line 12 or the output line 13. Multiple containers 01 located in the processing line 12 are clamped by clamping blocks 6 to keep the containers 01 stable. The flipping component 3 drives the processing line 12 and the containers 01 to flip synchronously, flipping the containers 01 so that the opening 02 faces upward, which facilitates subsequent steps such as filling the containers 01.

[0030] In this embodiment, the flipping component 3 includes a cylinder 36, which is connected to the left side of the processing line 12 and hinged to the right side of the processing line 12. When the cylinder 36 is started, it drives the processing line 12 and the container 01 to flip to the right, adjusting the opening 02 to an upward position. After completing the filling and other steps, the flipping component 3 and the clamping block 6 are reset, and the container 01 is guided from the processing line 12 to the output line 13.
