Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment and relates to a mechanism for ensuring flat stacking of packaging bags. Background Art

[0002] Automatic packaging machines are equipment that automatically weighs, fills and seals bulk materials, and are important equipment in the automated production of warehousing and logistics operations. With the application and promotion of automatic packaging equipment in the fields of petroleum, chemical, feed and other industries, the requirements for the automated operation level of the packaging process are also increasing.

[0003] In the fully automatic packaging process, in order to take out the stacked bags one by one from the bag warehouse, the bag-taking suction cup must be able to accurately and reliably suck up the bags, and then transport the bags to the position of the bag-taking manipulator through the conveying system. The bag-taking suction cup cooperates with the lifting bag warehouse to suck up the bags through the suction cup. The lifting bag warehouse needs to provide flat bags so that the bag-taking suction cup can smoothly establish vacuum to complete the bag-taking operation and enter the next step of the bag delivery and opening operation process.

[0004] In current production, due to the inconsistency between the bottom thickness of the finished packaging bag and the thickness at the opening, when a pile of packaging bags in the bag warehouse is stacked in the direction of the opening, the side will form a slope problem with the opening being low and the bottom being high. When the bag-picking suction cup sucks the packaging bag from the side of the packaging bag, the bag-picking surface of the packaging bag is not level, which affects the ability of the bag-picking suction cup to establish a vacuum, resulting in bag-picking failure. Taking the packaging bag thickness of 1mm as an example, the height of 300 packaging bags is about 300mm. Since the bottom of the packaging bag has a folded edge and stitching, the thickness is about 2.1 times that of the packaging bag, and the thickness of the flange at the head of the packaging bag is about 2 times that of the packaging bag, the tail of the packaging bag will be tilted to about 330mm, and the head of the packaging bag will be tilted to about 300mm. Therefore, it is urgent to provide a mechanism to ensure that the upper surface of the entire stack of packaging bags in the lifting bag warehouse is flat, so that the bag-picking suction cup can accurately and reliably pick up the packaging bag. Summary of the invention

[0005] The invention provides a mechanism for ensuring the flatness of packaging bags, which ensures the flatness of the upper surface of the entire stacked packaging bags, so that a bag-taking suction cup can accurately and reliably suck the packaging bags.

[0006] In order to solve the above technical problems, the present invention provides a mechanism for ensuring flat stacking of packaging bags, comprising: The bag store comprises a support surface, wherein the support surface comprises a first end and a second end disposed opposite to each other; A support plate, disposed at a first end of the support surface, the support plate comprising a support inclined surface inclined downward along the support surface; A tail assembly, comprising a floating tail rotatably connected to the second end of the support surface and a driving assembly for driving the floating tail; Among them, the support plate and the floating tail can be supported on the head and tail of the stacked packaging bags respectively, and the driving component can drive the floating tail to move to the same plane position as the support surface or to a position inclined downward from the support surface.

[0007] In one embodiment of the present invention, the driving assembly is an electric push rod.

[0008] In one embodiment of the present invention, the bag storage includes a frame, and the tail wing assembly also includes a connecting beam and a connecting bracket respectively connected to the frame, the tail end of the electric push rod is rotatably connected to the connecting bracket, one end of the floating tail wing in the width direction is rotatably connected to the connecting beam, and the other end of the floating tail wing in the width direction is rotatably connected to a rotating arm rotatably connected to the driving end of the electric push rod.

[0009] In one embodiment of the present invention, the other end of the floating tail in the width direction is connected to a mounting shaft rotatably connected to the rotating arm.

[0010] In one embodiment of the present invention, the supporting inclined surface forms an angle of 45° with the supporting surface.

[0011] In one embodiment of the present invention, the support plate further includes a support plane extending from an outer end of the support inclined surface and parallel to the support inclined surface.

[0012] In one embodiment of the present invention, a folded plate is extended along the outer end of the floating tail and is arranged perpendicular to the plane of the floating tail.

[0013] The above technical solution of the present invention has the following advantages compared with the prior art: The mechanism for ensuring flat stacking of packaging bags described in the present invention can adapt to changes in the height of the stacked packaging bags in a timely manner by quickly adjusting the angle of the floating tail wing, ensuring that each packaging bag can achieve optimal flatness before taking the bag, ensuring the flatness of the upper surface of the entire stack of packaging bags, and effectively solving the problem of uneven thickness caused by the folding and stitching of the bottom of the packaging bags, so that the bag taking suction cup can accurately and reliably absorb the packaging bags, thereby ensuring the continuity and efficiency of the production process.

[0025] In the present invention, unless otherwise clearly defined, the words "set", "install", "connect" and the like should be understood in a broad sense, for example, they can be directly connected or indirectly connected through an intermediate medium; they can be fixedly connected or detachably connected or integrally formed; they can be mechanically connected or electrically connected or able to communicate with each other; they can be the internal connection of two elements or the interaction relationship between two elements. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0026] Reference Figures 1 to 4 As shown, a mechanism for ensuring flat stacking of packaging bags of the present invention comprises: The bag storage 1 comprises a support surface 11, wherein the support surface 11 comprises a first end and a second end which are arranged opposite to each other; A support plate 2, disposed at a first end of the support surface 11, the support plate 2 comprising a support inclined surface 21 inclined downward along the support surface 11; The tail assembly 3 includes a floating tail 31 rotatably connected to the second end of the support surface 11 and a driving assembly 32 for driving the floating tail 31; Among them, the support plate 2 and the floating tail 31 can respectively support the head and tail of the stacked packaging bags, and the driving component 32 can drive the floating tail 31 to move to the same plane position as the supporting surface 11 or to a position inclined downward from the supporting surface 11.

[0027] In one embodiment, the driving assembly 32 is an electric push rod.

[0028] In one embodiment, the bag warehouse 1 includes a frame 12, and the tail wing assembly 3 also includes a connecting beam 33 and a connecting bracket 34 respectively connected to the frame 12, the tail end of the electric push rod is rotatably connected to the connecting bracket 34, one end of the floating tail wing 31 in the width direction is rotatably connected to the connecting beam 33, and the other end of the floating tail wing 31 in the width direction is rotatably connected to a rotating arm 35 rotatably connected to the driving end of the electric push rod.

[0029] In one embodiment, the other end of the floating tail wing 31 in the width direction is connected to a mounting shaft 36 rotatably connected to the rotating arm 35 .

[0030] In one embodiment, the support slope 21 and the support surface 11 form an angle of 45°.

[0031] In one embodiment, the support plate 2 further includes a support plane 22 extending from an outer end of the support inclined surface 21 and parallel to the support inclined surface 21 .

[0032] In one embodiment, a folded plate 37 is extended along the outer end of the floating tail 31 and is arranged perpendicular to the plane of the floating tail 31 .

[0033] When working, refer to Figure 5 , Figure 6 As shown, when the electric push rod is in the initial position, the floating tail 31 and the support surface 11 of the bag store 1 form an angle of 45°, and when the electric push rod is extended to the limit position, the floating tail 31 and the support surface 11 of the bag store 1 are in the same plane. The bag store 1 can be lifted and lowered in conjunction with the lifting mechanism 4 (such as a linear lifting module, etc.).

[0034] When the bag storehouse 1 is at the lowest position, the floating tail 31 is at an angle of 45° to the lifting bag storehouse 1, and the height of the tail of the packaging bag is below the support surface 11 of the bag storehouse 1. The stacked packaging bags are continuously taken away by the bag taking mechanism 5 (such as a suction cup controlled by a manipulator), and the height of the stacked packaging bags is continuously reduced. Through the control of the electric push rod, the angle between the floating tail 31 and the support surface 11 of the bag storehouse 1 is continuously reduced, and the height of the bag storehouse 1 is continuously reduced until the packaging bags are completely taken away, and the floating tail 31 is finally in the same plane as the support surface 11 of the lifting bag storehouse 1. In summary of this process, the electric push rod can make the angle adjustment of the floating tail 31 accurate and reliable, and the response speed is high by cooperating with the rotary encoder. The angle adjustment of the floating tail 31 ensures that the tail of the stacked packaging bags is a flat plane with the upper plane, thereby solving the problem that the bag taking suction cup can accurately and reliably absorb the packaging bags, improving the accuracy of the packaging bags, and at the same time improving the accuracy of the filling, reducing the labor intensity of the operator.

[0035] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
