Description

Technical Field

[0001] This invention relates to the field of plastic product manufacturing technology, and more specifically to an intelligent handling device for plastic product manufacturing. Background Technology

[0002] After production, plastic granules need to be handled and stacked. Existing stacking equipment cannot flatten plastic packaging bags, affecting the flatness of the stacks.

[0003] Existing technology uses a moving roller to rotate in one direction to smooth out packaging bags containing items to be stacked. However, when the items inside the packaging bag are compacted, the smoothing effect is limited by simply rotating the moving roller in one direction.

[0004] Moreover, the grippers of existing palletizing mechanisms can only clamp the packaging bags from both sides, and the packaging bags are prone to falling off during high-speed movement.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

The robotic arm includes: a moving frame, first grippers hinged to both sides of the moving frame in the width direction, and a clamping cylinder that drives the first grippers to rotate towards the center to clamp materials. A pressing cylinder is fixedly connected to the moving frame, and a pressing plate is fixedly mounted on the piston rod of the pressing cylinder.

[0008] Furthermore: a second gripper is provided on both sides of the moving frame along its length.

[0009] Furthermore, the smoothing mechanism includes: a push cylinder, a movable frame connected to the piston rod of the push cylinder, and a smoothing roller rotatably mounted within the movable frame.

[0010] Furthermore: the concentrating plate is composed of a bending part, a concentrating part, and a positioning part. A locking positioning component is fixedly connected to the lower part of the moving frame, and the locking positioning component slides in contact with the positioning part of the concentrating plate.

[0011] Furthermore, a hammer is slidably mounted on the positioning part of the central plate, which contacts the packaging bag laterally. One end of the hammer passes through the central part of the central plate to hammer the packaging bag, and the other end of the hammer slides in contact with the locking positioning part.

[0012] Furthermore, the part where the hammer and the engaging positioning member slide in contact is hemispherical, and the surface where the engaging positioning member and the hammer contact is curved.

[0013] Furthermore: a first spring is provided on the hammer, one end of the first spring abuts against the central part, and the other end of the first spring abuts against the abutting part on the hammer.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0029] like Figures 1 to 9 As shown, the intelligent handling equipment for the production of plastic products of the present invention includes: a first flow line 1, a second flow line 2 and a third flow line 3. The first flow line 1 is provided with a smoothing mechanism, the second flow line 2 is provided with a pallet feeding mechanism, and the first flow line 1 and the third flow line 3 are transported between each other by a handling mechanism.

[0030] In other words, the pallet 7 flows from the second flow line 2 to the third flow line 3. The material is smoothed by the smoothing mechanism on the first flow line 1 and then transported to the pallet 7 by the handling mechanism.

[0031] The pallet feeding mechanism includes: a storage rack 4, a lifting plate 5, and a distribution plate 6; the storage rack 4 is located at one end of the second flow line 2, and multiple pallets 7 are placed inside the storage rack 4 in sequence; the lifting plate 5 contacts the bottommost pallet 7 and drives the entire row of pallets 7 to rise or fall; the distribution plate 6 is located on both sides of the storage rack 4, and the distribution plate 6 moves towards the middle and inserts into the space between the pallets 7 inside the storage rack 4.

[0032] As can be seen from the above description, the lifting plate 5 is connected to a lifting cylinder 8 that drives its movement, and the distributing plate 6 is connected to a distributing cylinder 9 that drives its movement; a guide rod 10 is fixedly connected to the lifting plate 5, and a guide sleeve 11 is fixedly installed on the fixed plate. The guide rod 10 is inserted into the guide sleeve 11 and slides in contact with it, so that the guide rod 10 and the guide sleeve 11 cooperate to position the movement of the lifting plate 5; a fixed frame 12 is fixedly installed on both sides of the second flow line 2, and a guide slide rail 13 is fixedly installed on the fixed frame 12. A guide slider 14 is slidably installed on the guide slide rail 13, and the guide slider 14 slides in contact with the guide slide rail 13. The distributing plate 6 is fixedly installed on the guide slider 14, so that the distributing cylinder 9 can drive the distributing plate 6 to move.

[0033] It should be noted that the second flow line 2 is a belt conveyor with belts on both sides. The two sides of the tray 7 are in contact with the belts, which drives the tray 7 to move. The storage rack 4 has openings for the material distribution plate 6 to be inserted.

[0034] The handling mechanism includes: a column 15, a frame 16, a first moving module 17 mounted on the frame 16, a second moving module 18 mounted on the first moving module 17, a third moving module 19 mounted on the second moving module 18, and a robotic arm 20 mounted on the third moving module 19. An inclined reinforcing column 21 is fixedly installed between the column 15 and the frame 16 to enhance the connection strength between them.

[0035] The first moving module 17, the second moving module 18, and the third moving module 19 are all common linear modules; this application will not elaborate on them here.

[0036] In this application, visual modules can be set up as needed to make palletizing more intelligent.

[0037] The robotic arm 20 includes: a movable frame 22, first grippers 23 hinged to both sides of the movable frame 22 in the width direction, and a clamping cylinder 24 that drives the first grippers 23 to rotate towards the center to clamp the material. The movable frame 22 is fixedly connected to the third movable module 19, so that the third movable module 19 can drive the movable frame 22 to move, thereby realizing the three-axis movement of the robotic arm 20.

[0038] It should be explained here that the clamping cylinder 24 is installed at an angle on both sides of the movable frame 22. A connecting rod 25 is hinged to the piston rod of the clamping cylinder 24. The other end of the connecting rod 25 is fixedly connected to the first gripper 23, thereby driving the first gripper 23 to rotate towards the center.

[0039] The first gripper 23 includes a connecting frame 26, the two ends of which are hinged to the movable frame 22. The connecting rod 25 is fixedly connected to the middle of the connecting frame 26. A crossbar 27 is fixedly connected to the lower end of the connecting frame 26. The first clamping rods 28 are fixedly installed on the crossbar 27 at equal intervals. The first clamping rods 28 can pass through the roller spacing of the first flow line 1.

[0040] A pressing cylinder 29 is fixedly connected to the movable frame 22. A pressing plate 30 is fixedly installed on the piston rod of the pressing cylinder 29. The pressing cylinder 29 drives the pressing plate 30 to move downward, pressing and fixing the material from above. Compared with traditional robotic arms, this application can fix the material from both below and above.

[0041] However, unlike reality, most existing robotic arms are mounted on robots. Traditional gantry palletizing mechanisms typically use suction cups for adsorption and fixation. While the high-speed movement of gantry palletizing mechanisms can improve palletizing efficiency when using robotic arms, heavy goods are prone to falling off. Although this application can fix materials from below and above, there is still a possibility of goods falling off.

[0042] Therefore, this application provides second grippers 31 on both sides of the moving frame 22 along its length to block the material from the length of the moving frame 22.

[0043] The second gripper 31 includes: a mounting frame 32, a rotating body 33 rotatably mounted on the mounting frame 32, and a second gripping rod 34 fixedly mounted on the lower part of the rotating body 33; the rotating body 33 is composed of a driven gear part, an inclined connecting part, and a horizontal fixing part. The driven gear part is provided with gear teeth 35, and a rack 36 is fixedly connected to the lower pressure plate 30. The rack 36 meshes with the driven gear part through the gear teeth 35, so that when the lower pressure cylinder 29 drives the lower pressure plate 30 to move downward, it can drive the second gripper 31 to rotate so as to approach the material, and vice versa.

[0044] It should be noted that the height of the second clamping rod 34 is slightly lower than the height of the first clamping rod 28. This is because when plastic granules are put into the bag, their length may be relatively long, and both ends may bend downwards and deform. Therefore, the height of the second clamping rod 34 is slightly lower than the height of the first clamping rod 28.

[0045] In other words, when this application is in use, the clamping cylinder 24 first drives the first gripper 23 to rotate towards the center to initially clamp and fix the material. After the material is lifted to a certain height, the pressing cylinder 29 drives the pressing plate 30 to move downward to press and fix the material from above. At the same time, the second gripper 31 rotates to fix the material again from the length direction of the moving frame 22. That is to say, this application can fix the material in multiple directions.

[0046] The smoothing mechanism includes: a push cylinder 37, a movable frame 38 connected to the piston rod of the push cylinder 37, and a smoothing roller 39 rotatably mounted inside the movable frame 38; the push cylinder 37 can drive the movable frame 38 to reciprocate, thereby causing the smoothing roller 39 to repeatedly rotate and move on the surface of the material to smooth the material.

[0047] However, in actual use, a concentrating plate 40 is needed to concentrate the material below the smoothing roller 39 so that the smoothing roller 39 can smooth it.

[0048] The concentrating plate 40 is composed of a bending part 41, a concentrating part 42, and a positioning part 43; the bending part 41 is a plate that is inclined outward, and its main function is to move the material at the edge towards the center; the concentrating part 42 is a parallel plate, and its main function is to shape the material; the positioning part 43 positions the movement of the moving frame 38 so that it can move stably.

[0049] It should be noted that the two ends of the smoothing roller 39 are connected to the moving frame 38 by bearings 47, so that the smoothing roller 39 can rotate under the action of friction when the moving frame 38 moves on the material.

[0050] In actual use, the plastic particles are inside the packaging bag. There are fewer plastic particles at the edge of the packaging bag, and the plastic particles are concentrated in the middle of the packaging bag. At this time, simply rolling the smoothing roller 39 on the packaging bag will have a limited smoothing effect.

[0051] In this invention, a locking and positioning component 44 is fixedly connected to the lower part of the movable frame 38. The locking and positioning component 44 slides in contact with the positioning part 43 of the central plate 40, thereby positioning the moving direction of the movable frame 38 and preventing it from shaking.

[0052] A hammer 45 is slidably mounted on the positioning part 43 of the concentrating plate 40, which contacts the packaging bag laterally. One end of the hammer 45 can pass through the concentrating part 42 of the concentrating plate 40 to hammer the packaging bag, and the other end of the hammer 45 slides in contact with the locking positioning part 44. The positioning part 43 and the concentrating part 42 position the movement of the hammer 45 so that it can move back and forth stably.

[0053] The part of the hammer 45 that slides in contact with the engaging positioning member 44 is hemispherical, and the surface of the engaging positioning member 44 that contacts the hammer 45 is curved. A first spring 46 is provided on the hammer 45. One end of the first spring 46 abuts against the central part 42, and the other end of the first spring 46 abuts against the abutting part on the hammer 45. Thus, under the combined action of the engaging positioning member 44 and the first spring 46, the hammer 45 is pushed to reciprocate and hammer the packaging bag, causing the plastic particles inside the packaging bag to move from the center to the edges on both sides.

[0054] To facilitate better movement of the plastic particles within the packaging bag to both sides, the smoothing roller 39 is mounted on the moving block 48 via a bearing 47. The moving block 48 is slidably disposed within the fixed groove. Specifically, the fixed groove is located on both sides of the moving frame 38, and a positioning rod 50 is fixedly installed within the fixed groove. The positioning rod 50 is inserted into the moving block 48 and slides in contact with it. A second spring 49 is fitted onto the positioning rod 50, which is used to push the moving block 48 back to its original position. A lifting block 51 is fixedly connected to the moving block 48. The upper surface of the central portion 42 of the central plate 40 is curved. During the movement of the moving frame 38, the smoothing roller 39 moves up and down under the action of the lifting block 51 and the second spring 49, thereby causing the plastic particles within the packaging bag to move from the center to the edges on both sides.
