[0001] The utility model relates to the technical field of grain packaging and palletizing, in particular to an automatic bag taking manipulator for a full-automatic packaging and palletizing production line. Background Art

[0002] Automatic palletizer is a high-tech product integrating machinery and electronics. Medium and low-level palletizers can meet the production needs of medium and low output. It can complete the palletizing of various products such as bags, rubber blocks, boxes, etc. according to the required grouping method and number of layers. The optimized design makes the stacking shape tight and neat. Palletizers can be used in assembly line packaging. At present, the assembly line packaging process for powder, granular and block materials includes weighing, bag supply, bag filling, bag sealing, bag inversion and shaping, metal detection, palletizing and other processes;

[0003] The palletizer uses a mechanical arm to control the gripping structure. It uses a mechanical arm to control the gripping structure to pick up the items to be palletized from the production line, transfer them to the palletizing position, and then visit and stack them in a certain pattern to complete the palletizing.

[0004] However, the shapes of the particles inside the existing bagged grains are not completely fixed, and the particles have a certain fluidity in the packaging bag. During the grabbing process, the packaging bag may be deformed and the center of gravity may change, causing the grain particles inside to flow in one direction. Finally, during stacking, if the particles inside the package are unevenly distributed, it may cause the bag to tilt and collapse after stacking, which is inconvenient to use. Utility Model Content

[0025] See also Figure 1-4The utility model provides an embodiment: an automatic bag-taking robot for a fully automatic packaging and palletizing production line, comprising a material guide plate 1, a cylinder box 11 is arranged below the material guide plate 1, the interior of the cylinder box 11 is a hollow structure design, a cross partition 12 is fixedly installed in the cylinder box 11, a plurality of symmetrically distributed servo cylinders 13 are fixedly installed on both sides of the cylinder box 11, the number of servo cylinders 13 on the same side is not less than two, the output end of the servo cylinder 13 is movably connected with a pneumatic rod 14, a mechanical clamping plate 15 is fixedly installed between the plurality of pneumatic rods 14 on the same side, the mechanical clamping plate 15 is an "L"-shaped structure design, and a material guide slope 16 is arranged on the bottom end surface of the mechanical clamping plate 15,

[0026] With this structural design, when it is necessary to transfer and stack granular packaging bags such as grain, the servo cylinders 13 can work at the same time. When the servo cylinders 13 work, they drive the pneumatic rod 14 to extend, so that the extension of the pneumatic rod 14 drives the mechanical clamping plate 15 at the top to move, and the distance between the two mechanical clamping plates 15 increases.

[0027] The grain bag can be wrapped on both sides by the mechanical clamping plates 15 with increased distance. At this time, the mechanical clamping plates 15 are lowered by external hydraulic equipment. When the guide slope 16 at the bottom of the mechanical clamping plates 15 is lowered to the same level as the bottom of the grain bag, the external hydraulic equipment stops working, and the servo cylinder 13 drives the pneumatic rods 14 to retract, thereby reducing the distance between the two mechanical clamping plates 15. The two mechanical clamping plates 15 are used in coordination to complete the work of clamping the bagged grain.

[0028] When the mechanical clamping plate of this structural design is used, the overall surface area of ​​the mechanical clamping plate 15 is large, so the contact area with the grain bag is increased. By increasing the contact area of ​​the clamp, the grain particles inside can be effectively prevented from flowing in one direction. The structural design of the mechanical clamping plate 15 can effectively improve the force uniformity of the grain bag during clamping, so that the grasped packaging bag has better transportation stability, which is convenient for bag-taking and transportation of grain bags, and has good performance.

[0029] In this embodiment, lower baffles 2 are vertically connected to both sides of the lower surface of the guide plate 1, and a threaded rod 4 is installed at the center position between the two lower baffles 2 through a bearing. Guide rods 3 are fixedly installed on both sides of the threaded rod 4 and on the outer wall of the lower baffle 2. A threaded seat 5 is sleeved on the outer surface of the threaded rod 4, and the threaded seat 5 is threadedly connected to the threaded rod 4.

[0030] In this embodiment, in order to facilitate the limiting and guiding of the threaded seat 5, side ears 6 are fixedly installed on the outer walls of both sides of the threaded seat 5, the guide rod 3 passes through the side ears 6, and the side ears 6 and the guide rod 3 are slidably connected.

[0031] In this embodiment, a mounting seat 8 is fixedly mounted on the lower surface of the threaded seat 5, a steering motor 9 is fixedly mounted on the lower surface of the mounting seat 8, and a steering wheel 10 is fixedly mounted on the output shaft of the steering motor 9;

[0032] Furthermore, the lower surface of the steering wheel 10 is fixedly connected to the upper surface of the cylinder box 11 .

[0033] In this embodiment, in order to provide rotational power to the threaded rod 4, one end of the threaded rod 4 is fixedly connected to the output shaft of the servo motor 7, and the servo motor 7 is fixedly installed on the outer wall of the lower baffle 2 by bolts;

[0034] With this structural design, when the mechanical clamping plate 15 grabs the grain bag and performs the lifting work, the servo motor 7 can work. When the servo motor 7 works, it can drive the threaded rod 4 to rotate. Since the threaded rod 4 is externally threadedly connected with the threaded seat 5, when the threaded rod 4 rotates, the threaded seat 5 thereon will move in another direction, thereby driving the material on the mechanical clamping plate 15 to move from one end to the other end through the movement of the threaded seat 5, so that the grabbed grain bag can be transferred conveniently, which is convenient for the subsequent stacking work.

[0035] Furthermore, by arranging a steering motor 9 below the threaded seat 5, the steering motor 9 can conveniently drive the mechanical clamping plate 15 to rotate, so that the angle of the bag body can be adjusted during the transfer process, providing an adjustment effect and having better performance.

[0036] Working principle: Before use, the guide plate 1 of the utility model can be connected to an external hydraulic device, so that the utility model can be driven by the external hydraulic device to perform overall lifting work, so as to perform grabbing and stacking work on a workbench of suitable height;

[0037] When it is necessary to transfer and stack granular packaging bags such as grain, the servo cylinders 13 can work at the same time. When the servo cylinders 13 work, they drive the pneumatic rod 14 to extend, so that the extension of the pneumatic rod 14 drives the mechanical clamping plate 15 at the top to move, and the distance between the two mechanical clamping plates 15 increases.

[0038] The grain bag can be wrapped on both sides by the mechanical clamping plates 15 with increased distance. At this time, the mechanical clamping plates 15 are lowered by external hydraulic equipment. When the guide slope 16 at the bottom of the mechanical clamping plates 15 is lowered to the same level as the bottom of the grain bag, the external hydraulic equipment stops working, and the servo cylinder 13 drives the pneumatic rods 14 to retract, thereby reducing the distance between the two mechanical clamping plates 15. The two mechanical clamping plates 15 are used in coordination to complete the work of clamping the bagged grain.

[0039] After the grain bag is grabbed, the external hydraulic equipment is retracted, driving the utility model to rise as a whole. When the mechanical clamping plate 15 grabs the grain bag and performs the lifting work, the servo motor 7 can work. When the servo motor 7 works, it can drive the threaded rod 4 to rotate. Since the threaded rod 4 is externally threaded with a threaded seat 5, when the threaded rod 4 rotates, the threaded seat 5 thereon will move in another direction, thereby driving the material on the mechanical clamping plate 15 to move from one end to the other end through the movement of the threaded seat 5, so that the grabbed grain bag can be transferred conveniently, which is convenient for the subsequent stacking work.

[0040] Furthermore, by arranging a steering motor 9 below the threaded seat 5, the steering motor 9 can conveniently drive the mechanical clamping plate 15 to rotate, so that the angle of the bag body can be adjusted during the transfer process, providing an adjustment effect and having better performance.

[0041] When the utility model is in use, since the overall surface area of ​​the mechanical clamp is large, the contact area with the grain bag will increase. By increasing the contact area of ​​the clamp, the internal grain particles can be effectively prevented from flowing in one direction. The structural design of the mechanical clamp can effectively improve the force uniformity of the grain bag during clamping, so that the grasped packaging bag has better transportation stability, which is convenient for the bag retrieval and transportation of the grain bag, and has good performance.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
