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 process of automatic bag picking and bagging of the fully automatic packaging machine, the accuracy of bag positioning on the horizontal bag delivery platform is the basis for the accurate opening and bagging of the bag support robot arm. In the current bag delivery technology, the bag delivery conveyor belt is prone to deviation when transferring the bag to the bag opening, and the bag is not accurately positioned at the bag opening, which affects the accuracy of the bag support robot arm opening and bagging. Summary of the invention

[0004] The present invention provides a bag delivery centering mechanism, which can perform a centering operation on the bag delivery platform after a bag taking suction cup takes out a packaging bag from a bag warehouse and places it on a conveyor belt of a bag delivery platform, thereby ensuring that the packaging bag is always in the center of the conveyor line during the delivery process, thereby improving the accuracy of opening and putting on the bag by a bag holding mechanical arm.

[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 Figure 1 , Figure 2 As shown, a bag feeding and centering mechanism of the present invention comprises: The centering assembly 1 comprises a first centering baffle assembly 11 and a second centering baffle assembly 12 which are arranged opposite to each other, wherein the first centering baffle assembly 11 and the second centering baffle assembly 12 are arranged on both sides of the conveying line 3 in the width direction; The centering adjustment assembly 2 comprises a centering screw rod 21, a first seat body 22 and a second seat body 23, wherein the centering screw rod 21 comprises a first end thread and a second end thread in opposite directions, wherein the first end thread and the second end thread are threadedly connected with a first end nut and a second end nut connected to the first seat body 22 and the second seat body 23 respectively, and the first seat body 22 and the second seat body 23 are connected to the first centering baffle assembly 11 and the second centering baffle assembly 12 respectively; The relative distance between the first centering baffle assembly 11 and the second centering baffle assembly 12 can be adjusted by rotating the centering screw rod 21 .

[0027] By setting the centering component 1 and the centering adjustment component 2, the packaging bag can be accurately centered to ensure that the packaging bag is always in the center of the conveyor belt during the transportation process, which greatly improves the accuracy of the robot arm taking the bag in the next process and reduces production errors.

[0028] In one embodiment, the first pair of centering baffle assemblies 11 and the second pair of centering baffle assemblies 12 each include a telescopic member 13 correspondingly mounted on the first base body 22 or the second base body 23 and a movable frame 14 connected to the telescopic end of the telescopic member 13, wherein the movable frame 14 has a plurality of baffles 15 evenly spaced apart.

[0029] Specifically, the telescopic member 13 is a cylinder.

[0030] In one embodiment, the movable frame 14 includes an arched curved plate 141 and a straight plate 142 symmetrically extending at both ends of the curved plate 141 and extending along the length direction of the conveyor line 3. A plurality of embedding grooves 143 suitable for embedding the baffle 15 are spaced apart at the bottom end of the straight plate 142.

[0031] In one embodiment, referring to Figure 3 As shown, the conveyor line 3 uses a conveyor belt, including conveyor rollers 31 evenly spaced, and the baffles 15 are rectangular strips. Each baffle 15 is inclined to the plane of the conveyor line 3 and can be inserted into the gap between adjacent conveyor rollers 31.

[0032] Specifically, the baffle 15 is made of a flexible material; specifically, the material of the baffle 15 includes POM (polyoxymethylene) plastic. This makes the sheet-shaped baffle 15 flexible and bendable, and can be inserted into the conveyor belt, so that the baffle 15 contacts the packaging bag without a gap, and can effectively protect the packaging bag from scratches or damage.

[0033] In one embodiment, a guide rod 26 is further included. The first seat body 22 is provided with a first linear bearing group 24 , and the second seat body 23 is provided with a second linear bearing group 25 . The guide rod 26 is slidably connected to the first linear bearing group 24 and the second linear bearing group 25 .

[0034] Specifically, there are two guide rods 26 symmetrically disposed on both sides of the centering screw rod 21 .

[0035] Specifically, the first and second limit seats 27 and 28 are respectively connected to the sides of the first and second seats 22 and 23 at both ends of the guide rod 26. During installation, the first and second limit seats 27 and 28 can be fixed on both sides of the conveyor line.

[0036] The design of the guide rod 26 and the linear bearing group enhances the stability and durability of the entire mechanism, ensuring reliability in long-term high-frequency use.

[0037] Specifically, an adjusting hand wheel 29 connected to the end of the centering screw rod 21 is disposed on the outer side of the first limiting seat 27 or the second limiting seat 28 .

[0038] By shaking the adjusting hand wheel 29, the centering screw rod 21 can be rotated to adjust the centering width to suit packaging bags of different widths.

[0039] When in use, the centering position between the first centering baffle assembly 11 and the second centering baffle 15 is adjusted according to the size of the packaging bag. When the telescopic member 13 (cylinder) is in the extended state, the distance between the first centering baffle assembly 11 and the second centering baffle 15 is greater than the width of the packaging bag 140mm. The bag-taking mechanism (suction cup) sucks the packaging bag and places it on the conveyor line 3. The two cylinders retract, and the distance between the first centering baffle assembly 11 and the second centering baffle 15 is equal to the width of the packaging bag, so that the packaging bag is limited by the relative centering baffle 15, and further the central symmetry line of the packaging bag and the symmetry line between the first centering baffle assembly 11 and the second centering baffle 15 are on the same center line, ensuring the accuracy of the robot arm taking the bag in the next process.

[0040] 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.
