Description

Technical Field

[0001] The utility model relates to the technical field of medicine and food packaging machinery, in particular to an integrated walking beam. Background Art

[0002] The walking beam uses a connecting rod assembly and a servo motor as the power source. It can accurately transport the packaging materials to each station. The full servo power drive and flexible motion curve make it have the advantages of soft movement and stable transportation. Compared with the traditional synchronous belt structure, the walking beam structure is simple, has no sanitary dead corners, and is easy to clean; the existing walking beam structure includes a bottle-driving mechanism and a bottle-supporting mechanism. The bottle-driving mechanism is controlled by two independent servo motors to control a set of connecting rod mechanisms, driving the toothed plate to transport the packaging materials forward. When the bottle-driving mechanism returns, the bottle-supporting mechanism needs to drive the bottle-supporting plate to clamp the main packaging material to make it stable.

[0003] However, in the existing walking beam structure, the bottle leaning mechanism adopts a fixed swing arm structure, so that the actual movement curve of the bottle leaning plate is an arc, which will shake the packaging materials when approaching and leaving the bottle; the bottle chasing mechanism and the bottle leaning mechanism are independently installed on the equipment table, and there are difficult-to-eliminate processing errors and cumulative installation errors in the mounting holes, making it difficult to align the bottle leaning plate and the bottle chasing plate workstations, increasing the difficulty of debugging and processing, and also causing the packaging materials to shake during transportation; and the bottle chasing mechanism and the bottle leaning mechanism are independently installed, so that the walking beam system requires at least 4 mounting columns, which increases the difficulty of cleaning.

DETAILED DESCRIPTION

[0031] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] The utility model embodiment is an integrated walking beam, such as Figure 1-3 As shown, it includes a rotating shaft assembly 2, a connecting rod assembly 4, a bottle-driving plate 6 that moves along a parallelogram trajectory, and a bottle-supporting plate 7 that moves along a straight trajectory. The rotating shaft assembly 2 is connected to the bottle-driving plate 6 through the connecting rod assembly 4. The bottle-supporting plate 7 is arranged above the bottle-driving plate 6. A rotatable third driving shaft 3 is coaxially arranged in the rotating shaft assembly 2. A bottle-supporting arm 5 that is slidably connected to the bottle-supporting plate 6 is arranged on the third driving shaft 3. A guide shaft 1 parallel to the straight trajectory is arranged on the bottle-supporting plate 6. A fixing 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 rotating shaft 21 and a second rotating shaft 22.

[0033] The guide shaft 1 is detachably connected to the bottle support plate 6 to adjust the relative position of the guide shaft 1 and the bottle support plate 6 and eliminate the origin error of the working position on the bottle support plate 7 and the bottle driving plate 6.

[0034] A sliding shaft 71 is provided on the bottle supporting plate 6 , the bottle supporting arm 5 is slidably connected to the sliding shaft 71 , and the guide shaft 1 is detachably connected to the sliding shaft 71 .

[0035] In this embodiment, the connecting rod assembly 4 includes a first connecting rod 41, a second connecting rod 42, a third connecting rod 43 and a fourth connecting rod 44. One end of the first connecting rod 41 is fixedly connected to the first rotating shaft 21, and the other end is hinged to one end of the fourth connecting rod 44. One end of the second connecting rod 42 is fixedly connected to the second rotating shaft 22, and the other end is hinged to an appropriate middle position of the fourth connecting rod 44 through the third connecting rod 43. The other end of the fourth connecting rod 44 is connected to the bottle-driving plate 6; the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 form a parallelogram connecting rod assembly 4, which realizes the parallelogram trajectory movement of the bottle-driving plate 6 connected to the fourth connecting rod 44, and realizes the actions of walking to drive bottles, walking backward, walking back, and walking forward in turn, respectively, as shown in FIG. Figure 6 Middle a, Figure 6 Middle b, Figure 6 Middle c, Figure 6The movement 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 shown in d indicates that the bottle-chasing plate 6 grabs the bottle at position 1, moves it to position 2 and puts it down, and the bottle-chasing plate 6 returns to position 1 from position 2 via position 3 and position 4 in sequence, and continues to grab the bottle from position 1, moves it to position 2 and puts it down, and repeats this cycle.

[0036] However, after the bottle-driving board 6 puts down the bottle at position 2, in order to prevent the bottle from shaking and falling, the bottle-supporting board 7 located above the bottle-driving board 6 needs to move forward and get close to the bottle. When the bottle-driving board 6 grabs the bottle at position 1, the bottle-supporting board 7 moves backward and away from the bottle. To this end, the utility model realizes the linear trajectory movement of the bottle-supporting board 7 through the bottle-supporting arm 5 and the guide shaft 1.

[0037] In this embodiment, a sliding shaft 71 is provided on the bottle support plate 6, and the bottle support plate 7 is connected to the sliding shaft 71 through a bottle support connecting block 72; one end of the bottle support arm 5 is fixedly connected to the third driving shaft 3, and the other end is slidably connected to the sliding shaft 71, and the sliding shaft 71 is connected to the bottle support 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, and the fixed seat 11 is arranged above the third driving shaft 3 through the fixed plate 12, and the sliding direction of the guide shaft 1 is the same as the moving direction of the bottle support plate 7, that is, the guide shaft 1 passes through the sliding hole on the fixed seat 11, and the fixed seat 11 is fixed and stationary, 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 driving shaft 3 drives the bottle support arm 5 to rotate, and the bottle support arm 5 drives the sliding shaft 71 to move, but the movement trajectory of the bottle support arm 5 is an arc, and the bottle support plate 7 needs to make a reciprocating linear motion perpendicular to the sliding shaft 71, and the horizontal movement of the bottle support plate 7 needs to be eliminated; as the third driving shaft 3 drives the bottle support arm 5 to rotate, the bottle support arm 5 drives the sliding shaft 71 to move, but under the guiding action of the transversely sliding guide shaft 1, the bottle support arm 5 slides on the sliding shaft 71, and the sliding direction of the guide shaft 1 is the same as the moving direction of the bottle support plate 7, pushing the sliding shaft 71 can only move forward or backward to make a linear motion, thereby driving the bottle support plate 7 as Figure 6 As shown in b, when the bottle-driving board 6 moves backward, it moves forward by the bottle, as shown in Figure 6 As shown in the figure d, the bottle-driving board 6 moves forward while the bottle-driving board moves backward. The simplified structure of the bottle-driving mechanism, the bottle-driving sliding mechanism, and the guide mechanism is shown in FIG. Figure 5 shown.

[0038] In this embodiment, an integrated installation is adopted, such as Figure 4As shown, the first rotating shaft 21, the second rotating shaft 22 and the third driving shaft 3 are coaxially mounted on the mounting seat 8 using a sleeve shaft structure. Since the bottle-receiving plate 7 is located above the bottle-driving plate 6, the bottle-receiving arm 5 is located above the connecting rod assembly 4, and the third driving shaft 3 is located above and at the center of the bottle-driving driving shaft. From the axis to the outside, the third driving shaft 3, the second rotating shaft 22 and the first rotating shaft 21 are arranged in sequence. The three driving shafts are independently driven by servo motors, the first rotating shaft 21 is connected to the first driving motor 91 and the corresponding reducer, the second rotating shaft 22 is connected to the second driving motor 92 and the corresponding reducer, and the third driving shaft 3 is connected to the third driving motor 93 and the corresponding reducer.

[0039] In addition, the guide shaft 1 is detachably connected to the sliding shaft 71, so that the relative position of the guide shaft 1 and the sliding shaft 71 can be adjusted, which is used to eliminate the origin error of the workstations on the bottle support plate 7 and the bottle driving plate 6; because the bottle support plate 7 must cooperate with the movement trajectory of the bottle driving plate 6 to prevent the bottles from shaking and tipping over, the bottle driving plate 6 and the bottle support plate 7 should be completely aligned, but the bottle driving plate 6 and the bottle support plate 7 are processed and assembled separately, and there is an origin error caused by processing and assembly, which in turn causes a deviation in the workstation position and causes the bottles to shake and tip over. Therefore, one end of the guide shaft 1 is fixed to the sliding shaft 71 by screws, and the relative position of the guide shaft 1 and the sliding shaft 71 is adjusted by loosening the screws, thereby driving the bottle support plate 7 to be completely aligned with the workstations on the bottle driving plate 6.

[0040] In this embodiment, the bottle receiving plate 7 and the bottle driving plate 6 are both made of an integrated aluminum alloy material, which is lighter and more precise than a plate made of channel steel.

[0041] In this embodiment, in order to make the movement of the bottle leaning plate 7 and the bottle driving plate 6 more stable, at least two groups of bottle leaning sliding mechanisms and guide mechanisms are provided.

[0042] The integrated walking beam of this embodiment has three states which are repeated in sequence:

[0043] State 1: The bottle-driving shaft drives the bottle-driving plate 6 through the connecting rod assembly 4 to move the bottle forward from the bottle-taking position to the bottle-putting position; the bottle-receiving plate 7 remains in the retracted state;

[0044] like Figure 6 As shown in a, the bottle taking position to the bottle placing position is from position 1 to position 2.

[0045] State 2: After the bottle-driving plate 6 puts down the bottle at the bottle-dropping position, the bottle-driving driving shaft drives the bottle-driving plate 6 to move to the bottle-taking position through the connecting rod assembly 4; the third driving shaft 3 drives the bottle-dropping plate 7 to move forward and maintain the forward state through the bottle-dropping sliding mechanism and the guide mechanism;

[0046] Since the connecting rod assembly 4 is a rectangular motion track, the bottle-driving shaft drives the bottle-driving plate 6 through the connecting rod assembly 4 to put down the bottle at the bottle-placing position, and then moves to the bottle-taking position along the rectangular motion track, such as Figure 6 Middle b, Figure 6 As shown in c, it moves from position 2 to position 3, then from position 3 to position 4, and continues to move from position 4 to position 1;

[0047] State three: the bottle-driving shaft drives the bottle-driving plate 6 to move to the bottle-taking position through the connecting rod assembly 4; the third driving shaft 3 drives the bottle-leaving plate 7 to retreat through the bottle-leaving sliding mechanism and the guide mechanism; return to state one;

[0048] like Figure 6 As shown in (d), from position 4 to position 1.

[0049] In summary, the above-mentioned integrated walking beam has the following beneficial effects:

[0050] (1) The utility model uses a transversely sliding guide shaft combined with a swing-driven bottle-leaving arm to change the bottle-leaving motion trajectory from an arc to a straight line, so that the bottle-leaving plate is not easy to shake when leaning against the bottle and leaving, which is beneficial to improving the stability of the walking beam packaging material conveying;

[0051] (2) The utility model provides a movable origin positioning structure in which the guide shaft and the bottle support plate are detachably connected, so that the relative position of the guide shaft and the bottle support plate can be adjusted, thereby aligning the working positions of the bottle support plate and the bottle driving plate, eliminating the working position origin error caused by the processing and assembly errors of the bottle support plate and the bottle driving plate, thereby improving the running stability and accuracy of the walking beam and reducing the processing and assembly difficulty of the walking beam;

[0052] (3) The utility model integrates the drive motor, drive shaft and transmission structure of the bottle-driving mechanism and the bottle-leaving mechanism, and the bottle-driving drive shaft and the bottle-leaving drive shaft are installed in a sleeve shaft, which reduces the bottle-leaving bearing seat, making the walking beam more compact, easier to clean and maintain, and lower in cost;

[0053] (4) The bottle support plate of the utility model is changed into a structure of a sliding shaft and a bottle support connecting block, which reduces weight and reduces the design error rate. In addition, the use of lighter materials is conducive to reducing weight and improving precision.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it; although the implementation mode of the utility model is 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 utility model, and such modifications and variations are all within the scope defined by the attached claims.
