Description

Technical Field

[0001] This invention relates to the field of pharmaceutical and food packaging machinery technology, and in particular to an integrated walking beam. Background Technology

[0002] The traveling beam uses a linkage assembly and a servo motor as its power source, enabling precise delivery of packaging materials to each workstation. The fully servo-driven power and flexible motion curve provide advantages such as smooth movement and stable delivery. Compared to traditional synchronous belt structures, the traveling beam structure is simple, has no dead corners, and is easy to clean. The existing traveling beam structure includes a bottle-pushing mechanism and a bottle-aligning mechanism. The bottle-pushing mechanism is controlled by two independent servo motors, each controlling a linkage mechanism that drives a toothed plate to deliver the packaging materials forward. During the return stroke of the bottle-pushing mechanism, the bottle-aligning mechanism drives a bottle-aligning plate to hold the packaging materials in place, ensuring stability.

[0003] However, in the existing walking beam structure, the bottle-holding mechanism adopts a fixed swing arm structure, which makes the actual movement curve of the bottle-holding plate an arc. When approaching and leaving the bottle, the packaging material will sway, making it unstable. The bottle-pushing mechanism and the bottle-holding mechanism are independently installed on the equipment platform. The mounting holes have difficult-to-eliminate processing errors and cumulative installation errors, making it difficult for the bottle-holding plate and the bottle-pushing plate to be aligned. This increases the difficulty of debugging and processing, and also causes the packaging material to sway during transportation. Moreover, the independent installation of the bottle-pushing mechanism and the bottle-holding mechanism requires at least 4 mounting columns for the walking beam system, which increases the difficulty of cleaning. Summary of the Invention

[0004] (a) Technical problems to be solved To address the aforementioned problems, this invention provides an integrated walking beam that solves the issues of packaging material swaying and becoming unstable when the bottle-holding mechanism approaches and leaves, and the difficulty in aligning the bottle-holding plate and the bottle-pushing plate stations due to processing and assembly errors, which causes swaying during packaging material transportation.

[0005] (II) Technical Solution Based on the above-mentioned technical problems, the present invention provides an integrated walking beam, including a coaxial first drive shaft and a second drive shaft, a linkage assembly, a bottle-pushing plate that moves along a parallelogram trajectory, and a bottle-supporting plate that moves along a straight trajectory. The first drive shaft and the second drive shaft are connected to the bottle-pushing plate through the linkage assembly. The bottle-supporting plate is disposed above the bottle-pushing plate. A rotatable third drive shaft is coaxially disposed within the first drive shaft and the second drive shaft. A bottle-supporting arm that is slidably connected to the bottle-supporting plate is disposed on the third drive shaft. A guide shaft that is parallel to the straight trajectory is disposed on the bottle-supporting plate. A fixed seat that slides relative to the guide shaft is disposed on the guide shaft.

[0006] Furthermore, the guide shaft is detachably connected to the bottle-supporting plate, which is used to adjust the relative position of the guide shaft and the bottle-supporting plate, and eliminate the origin error of the working position on the bottle-supporting plate and the bottle-pushing plate.

[0007] Furthermore, the bottle support plate is provided with a sliding shaft, the bottle support arm is slidably connected to the sliding shaft, and the guide shaft is detachably connected to the sliding shaft.

[0008] Furthermore, the linkage assembly includes a first linkage, a second linkage, a third linkage, and a fourth linkage. One end of the first linkage is fixedly connected to the first drive shaft, and the other end is hinged to one end of the fourth linkage. One end of the second linkage is fixedly connected to the second drive shaft, and the other end is hinged at an appropriate position between the third and fourth linkages. The other end of the fourth linkage is connected to the bottle-driving plate.

[0009] Furthermore, the first drive shaft, the second drive shaft, and the third drive shaft are all coaxially mounted on the mounting base, and are arranged sequentially from the center outwards as the third drive shaft, the second drive shaft, and the first drive shaft.

[0010] Furthermore, the bottle-pushing plate and the bottle-holding plate are made of one-piece aluminum alloy.

[0011] Furthermore, the bottle-supporting plate is provided with a bottle-supporting connecting block that connects to the sliding shaft.

[0012] Furthermore, the mounting base is positioned above the third drive shaft via a mounting plate.

[0013] Furthermore, the bottle-holding arm is located above the linkage assembly.

[0014] Furthermore, the first drive shaft connects the first drive motor and the corresponding reducer, the second drive shaft connects the second drive motor and the corresponding reducer, and the third drive shaft connects the third drive motor and the corresponding reducer.

[0015] (III) Beneficial Effects The above-described technical solution of the present invention has the following advantages: (1) The present invention uses a guide shaft that slides laterally and a bottle-holding arm that is driven by a swing to change the bottle-holding trajectory from an arc to a straight line, so that the bottle-holding plate is not easy to shake when it is holding the bottle and leaving the bottle, which is beneficial to improving the stability of the conveying of the packaging material by the traveling beam. (2) The present invention uses a movable origin positioning structure that detachably connects the guide shaft and the bottle-supporting plate to make the relative position of the guide shaft and the bottle-supporting plate adjustable, thereby making the work positions of the bottle-supporting plate and the bottle-pushing plate aligned, eliminating the work position origin error caused by the processing and assembly errors of the bottle-supporting plate and the bottle-pushing plate, thereby improving the running stability and accuracy of the traveling beam, and also reducing the processing and assembly difficulty of the traveling beam. (3) The present invention integrates the drive motor, drive shaft and transmission structure of the bottle-driving mechanism and the bottle-holding mechanism, and the bottle-driving drive shaft and the bottle-holding drive shaft are mounted on the sleeve shaft, which reduces the bottle-holding bearing seat, making the walking beam more compact, easier to clean and maintain and lower in cost. (4) The present invention changes the structure of the bottle plate to a sliding shaft and a bottle connecting block, which reduces the weight, lowers the design error rate, and uses lighter materials, which helps to reduce weight and improve accuracy.

Detailed Implementation

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] An embodiment of the present invention is an integrated walking beam, such as... Figure 1-3As shown, the assembly includes a rotating shaft assembly 2, a connecting rod assembly 4, a bottle-pushing plate 6 that moves along a parallelogram trajectory, and a bottle-holding plate 7 that moves along a straight trajectory. The rotating shaft assembly 2 is connected to the bottle-pushing plate 6 via the connecting rod assembly 4. The bottle-holding plate 7 is located above the bottle-pushing plate 6. A rotatable third drive shaft 3 is coaxially arranged inside the rotating shaft assembly 2. A bottle-holding arm 5 that is slidably connected to the bottle-holding plate 7 is arranged on the third drive shaft 3. A guide shaft 1 that is parallel to the straight trajectory is arranged on the bottle-holding plate 7. A fixed seat 11 that slides relative to the guide shaft 1 is arranged on the guide shaft 1. The rotating shaft assembly 2 includes a coaxial first drive shaft 21 and a second drive shaft 22.

[0019] The guide shaft 1 is detachably connected to the bottle-supporting plate 7, which is used to adjust the relative position of the guide shaft 1 and the bottle-supporting plate 7, and eliminate the origin error of the working position on the bottle-supporting plate 7 and the bottle-pushing plate 6.

[0020] A sliding shaft 71 is provided on the bottle plate 7, the bottle arm 5 is slidably connected to the sliding shaft 71, and the guide shaft 1 is detachably connected to the sliding shaft 71.

[0021] In this embodiment, the linkage assembly 4 includes a first linkage 41, a second linkage 42, a third linkage 43, and a fourth linkage 44. One end of the first linkage 41 is fixedly connected to the first drive shaft 21, and the other end is hinged to one end of the fourth linkage 44. One end of the second linkage 42 is fixedly connected to the second drive shaft 22, and the other end is hinged to the third linkage 43 at an appropriate midpoint between the second and fourth linkages 44. The other end of the fourth linkage 44 is connected to the bottle-carrying plate 6. The first linkage 41, the second linkage 42, the third linkage 43, and the fourth linkage 44 form a parallelogram linkage assembly 4, enabling the bottle-carrying plate 6 connected to the fourth linkage 44 to move along a parallelogram trajectory, sequentially realizing the actions of walking to carry the bottle, walking backward, walking backward, and walking forward, respectively as follows. Figure 6 a, Figure 6 b, Figure 6 c, Figure 6 The sequence d in the diagram, from position 1 to position 2, from position 2 to position 3, from position 3 to position 4, and from position 4 to position 1, indicates that the bottle-grabbing plate 6 grabs the bottle at position 1, moves it to position 2 and puts it down. The bottle-grabbing plate 6 then moves from position 2 through position 3 and position 4 back to position 1, and continues to grab the bottle at position 1, move it to position 2 and put it down, and so on in a loop.

[0022] However, after the bottle-pushing plate 6 puts the bottle down at position 2, in order to prevent the bottle from shaking and tipping over, the bottle-supporting plate 7 located above the bottle-pushing plate 6 needs to move forward and get closer to the bottle. When the bottle-pushing plate 6 grabs the bottle at position 1, the bottle-supporting plate 7 moves backward and away from the bottle. For this purpose, the present invention realizes the linear trajectory movement of the bottle-supporting plate 7 through the bottle-supporting arm 5 and the guide shaft 1.

[0023] In this embodiment, a sliding shaft 71 is provided on the bottle-supporting plate 6, and the bottle-supporting plate 7 is connected to the sliding shaft 71 through a bottle-supporting connecting block 72; one end of the bottle-supporting arm 5 is fixedly connected to the third drive shaft 3, and the other end is slidably connected to the sliding shaft 71, which is connected to the bottle-supporting plate 7; one end of the guide shaft 1 is detachably connected to the sliding shaft 71, and the other end is slidably connected to the fixed seat 11. The fixed seat 11 is located above the third drive shaft 3 through a fixed plate 12. The sliding direction of the guide shaft 1 is the same as the moving direction of the bottle-supporting plate 7, that is, the guide shaft 1 passes through the sliding hole on the fixed seat 11, the fixed seat 11 is fixed, one end of the guide shaft 1 is stationary on the sliding shaft 71, and the other end of the guide shaft 1... The length is adjusted by sliding on the fixed seat 11; therefore, the third drive shaft 3 drives the bottle arm 5 to rotate, and the bottle arm 5 drives the sliding shaft 71 to move. However, the movement trajectory of the bottle arm 5 is an arc, and the bottle plate 7 needs to make a reciprocating linear motion perpendicular to the sliding shaft 71. It is necessary to eliminate the horizontal movement of the bottle plate 7. As the third drive shaft 3 drives the bottle arm 5 to rotate, the bottle arm 5 drives the sliding shaft 71 to move. However, under the guidance of the horizontally sliding guide shaft 1, the bottle arm 5 slides on the sliding shaft 71. The sliding direction of the guide shaft 1 is the same as the movement direction of the bottle plate 7. The sliding shaft 71 can only move forward or backward in a straight line, thereby driving the bottle plate 7 as follows. Figure 6 As shown in b, when moving backward along the bottle plate 6, it moves forward by touching the bottle, as... Figure 6 As shown in diagram d, the bottle-pushing plate 6 moves forward while retracting towards the bottle. The simplified structure of the bottle-pushing mechanism, the bottle-sliding mechanism, and the guiding mechanism is as follows: Figure 5 As shown.

[0024] In this embodiment, an integrated installation is adopted, such as... Figure 4 As shown, the first drive shaft 21, the second drive shaft 22, and the third drive shaft 3 are all coaxially mounted on the mounting base 8 using a sleeve shaft structure. Since the bottle-supporting plate 7 is located above the bottle-pushing plate 6, the bottle-supporting arm 5 is located above the connecting rod assembly 4, and the third drive shaft 3 is located above and at the center of the bottle-pushing drive shaft, the order from the center outwards is: third drive shaft 3, second drive shaft 22, and first drive shaft 21. Each of the three drive shafts is independently driven by a servo motor. The first drive shaft 21 is connected to the first drive motor 91 and the corresponding reducer; the second drive shaft 22 is connected to the second drive motor 92 and the corresponding reducer; and the third drive shaft 3 is connected to the third drive motor 93 and the corresponding reducer.

[0025] Furthermore, the guide shaft 1 and the slide shaft 71 are detachably connected, allowing the relative position of the guide shaft 1 and the slide shaft 71 to be adjusted. This is used to eliminate the origin error of the working positions on the bottle-supporting plate 7 and the bottle-pushing plate 6. Since the bottle-supporting plate 7 needs to coordinate with the movement trajectory of the bottle-pushing plate 6 to prevent the bottles from shaking and tipping over, the bottle working positions on the bottle-pushing plate 6 and the bottle-supporting plate 7 should be perfectly aligned. However, the bottle-pushing plate 6 and the bottle-supporting plate 7 are processed and assembled separately, resulting in origin errors caused by processing and assembly. This causes the working position to deviate, and the bottles shake and tip over. Therefore, one end of the guide shaft 1 is fixed to the slide shaft 71 with screws. By loosening the screws, the relative position of the guide shaft 1 and the slide shaft 71 is adjusted, thereby driving the bottle-supporting plate 7 and the working positions on the bottle-pushing plate 6 to be perfectly aligned.

[0026] In this embodiment, both the bottle-supporting plate 7 and the bottle-pushing plate 6 are made of one-piece aluminum alloy, which is lighter and more precise than using channel steel.

[0027] In this embodiment, to make the movement of the bottle-supporting plate 7 and the bottle-pushing plate 6 more stable, at least two sets of bottle-supporting sliding mechanism and guiding mechanism are provided.

[0028] The operation method of the integrated traveling beam in this embodiment includes three states that are repeated cyclically: State 1: The bottle-driving drive shaft drives the bottle-driving plate 6 through the linkage assembly 4 to move the bottle from the bottle-picking position to the bottle-placing position; the bottle plate 7 keeps it in the retracting state; like Figure 6 As shown in Figure a, the position from the bottle-taking position to the bottle-placing position is from position 1 to position 2.

[0029] State 2: After the bottle-pushing plate 6 puts the bottle down at the bottle-placing position, the bottle-pushing drive shaft drives the bottle-pushing plate 6 to move towards the bottle-picking position through the linkage assembly 4; the third drive shaft 3 drives the bottle-holding plate 7 forward through the bottle-sliding mechanism and the guide mechanism and maintains the forward state. Since the linkage assembly 4 follows a rectangular motion trajectory, the bottle-pushing drive shaft, through the linkage assembly 4, drives the bottle-pushing plate 6 to place the bottle at the bottle-dropping position, and then moves along the rectangular motion trajectory towards the bottle-retrieving position. Figure 6 b, Figure 6 As shown in c, the movement proceeds from position 2 to position 3, then from position 3 to position 4, and continues from position 4 back to position 1. State 3: The bottle-pushing drive shaft drives the bottle-pushing plate 6 to move to the bottle-picking position via the linkage assembly 4; the third drive shaft 3 drives the bottle-holding plate 7 to retract via the bottle-holding sliding mechanism and the guide mechanism; returning to State 1; like Figure 6 As shown in d, the distance from position 4 to position 1 is reached.

[0030] In summary, the above-described integrated traveling beam has the following beneficial effects: (1) The present invention uses a guide shaft that slides laterally and a bottle-holding arm that is driven by a swing to change the bottle-holding trajectory from an arc to a straight line, so that the bottle-holding plate is not easy to shake when it is holding the bottle and leaving the bottle, which is beneficial to improving the stability of the conveying of the packaging material by the traveling beam. (2) The present invention uses a movable origin positioning structure that detachably connects the guide shaft and the bottle-supporting plate to make the relative position of the guide shaft and the bottle-supporting plate adjustable, thereby making the work positions of the bottle-supporting plate and the bottle-pushing plate aligned, eliminating the work position origin error caused by the processing and assembly errors of the bottle-supporting plate and the bottle-pushing plate, thereby improving the running stability and accuracy of the traveling beam, and also reducing the processing and assembly difficulty of the traveling beam. (3) The present invention integrates the drive motor, drive shaft and transmission structure of the bottle-driving mechanism and the bottle-holding mechanism, and the bottle-driving drive shaft and the bottle-holding drive shaft are mounted on the sleeve shaft, which reduces the bottle-holding bearing seat, making the walking beam more compact, easier to clean and maintain and lower in cost. (4) The present invention changes the structure of the bottle plate to a sliding shaft and a bottle connecting block, which reduces the weight, lowers the design error rate, and uses lighter materials, which helps to reduce weight and improve accuracy.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it; although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
