[0002] The coil is a cylindrical plastic film roll. After the coil is manufactured, it needs to be transported to various places for sale. In order to protect the integrity of the coil during transportation and handling, reduce wear, and increase the transportation quantity, the coil needs to be suspended and packaged. Suspended packaging can be understood as first independently packaging a single coil, covering the surface of the coil with bubble film, then buckling the two ends with a paper cover and a foam pad, and fixing with tape winding; then installing vertical clamping plates at both ends of the coil, and then bundling the two vertical clamping plates, so that the coil is suspended between the two vertical clamping plates. After the single coil is packaged, the coils are transported to the stacking station one by one and neatly stacked on a wooden pallet. When stacking, the vertical clamping plates of two coils need to be connected by fixing members. At present, the suspended packaging of coils in this industry is mainly manual packaging, with low work efficiency and low automation level. Therefore, it is necessary to automate the transformation of the coil suspended packaging production line to achieve the automatic installation of fixing members. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present invention provides a fixing member installation device for film roll palletizing. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further elaborates the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0025] Please refer to Figures 1-5, the present invention provides a fixing member installation device for palletizing film rolls, including a frame 1 having a film roll placement station 12, a feeding mechanism 2 arranged beside the film roll placement station 12, an x-axis slide 3 slidably arranged on the frame 1, an x-axis linear drive mechanism 4 for driving the x-axis slide 3 to move back and forth, a y-axis slide 5 slidably arranged on the x-axis slide 3, a y-axis linear drive mechanism 6 for driving the y-axis slide 5 to move left and right, a z-axis linear drive mechanism 7 arranged on the y-axis slide 5, and a gripper assembly 8 arranged on the z-axis linear drive mechanism 7; the z-axis linear drive mechanism 7 is used to drive the gripper assembly 8 to move up and down; the x-axis slide 3 is located above the film roll placement station 12; the gripper assembly 8 is used to grab the fixing member 9 on the feeding mechanism 2 and install it on the vertical clamping plate 14.

[0026] The fixing member is a workpiece for assisting palletizing, such as Figure 2 As shown, when the fixing member 9 is projected orthogonally from left to right, the fixing member 9 is in an H shape. The fixing member 9 includes a profile body in a "U" shape, and the profile body includes a bottom plate portion 91 and two vertical plate portions 92 respectively arranged on both sides of the bottom plate portion 91. The two vertical plate portions 92 and the bottom plate portion 91 enclose an upper notch. Each of the vertical plate portions 92 is provided with a flap 93 bent downward, and the two flaps 93 and the bottom plate portion 91 enclose a lower notch.

[0027] To facilitate the placement of the film roll, a support table 13 is arranged on the film roll placement station 12. The film roll is placed on the support table 13. Vertical clamping plates 14 are provided at both ends of the film roll 15, and the two vertical clamping plates 14 are fixed by bundling, so that the coil is suspended between the two vertical clamping plates 14; since the control system has obtained the current film roll specifications during film roll packaging, the specifications of the vertical clamping plates on the support table 13 can be determined, and thus the preset throwing height of the fixing member can be obtained.

[0028] Under the coordinated movement of the gripper assembly 8, the X-axis carriage 3, the X-axis linear drive mechanism 4, the Y-axis carriage 5, the Y-axis linear drive mechanism 6, and the Z-axis linear drive mechanism 7, the gripper assembly 8 flexibly moves in three-axis space. The gripper assembly 8 first moves above the loading point of the feeding mechanism 2, and then the Z-axis linear drive mechanism 7 drives the gripper assembly 8 to slowly descend. The gripper assembly 8 grabs the fixing member 9, extends into the upper slot of the fixing member 9, and sucks the fixing member 9. Then the gripper assembly 8 moves to the outside of the vertical clamping plate 14 and is at a suitable fixing member dropping height. Subsequently, the gripper assembly 8 moves in the direction close to the outer side of the vertical clamping plate. When the gripper assembly 8 moves above the vertical clamping plate 14, the gripper assembly 8 stops moving. At this time, the fixing member 9 is located directly above the vertical clamping plate. Then the Z-axis linear drive mechanism 7 drives the gripper assembly 8 to slowly move downward, so that the lower slot of the fixing member 9 is accurately clamped onto the top of the vertical clamping plate, completing the automatic installation of one fixing member 9. In fact, two fixing members 9 need to be installed front and back on each vertical clamping plate 14 to form four stable palletizing support points. Therefore, in order to improve the installation efficiency of the fixing member 9, in this embodiment, the Y-axis carriage 5, the Y-axis linear drive mechanism 6, the Z-axis linear drive mechanism 7, and the gripper assembly 8 are provided with two groups and are symmetrically arranged. Each gripper assembly 8 corresponds to the installation work of the fixing member 9 on one vertical clamping plate. The two gripper assemblies 8 synchronously perform the feeding and installation work, each completing the installation of two fixing members 9, realizing the automatic assembly of the fixing members, solving the problems of low efficiency and high labor cost in manual assembly, and better promoting the automatic transformation of the coil suspension packaging production line.

[0029] In this embodiment, the feeding mechanism 2 is a vibrating bowl feeder. A vibrating bowl feeder is a conventional automatic orienting and sorting feeding device. After a plurality of disordered fixing members 9 are placed on the tray of the vibrating bowl feeder, the disordered fixing members 9 are automatically arranged neatly by vibration and are accurately conveyed to the loading point one by one, so that the gripper assembly 8 can grab the fixing members 9.

[0030] Specifically, the gripper assembly 8 includes a bracket 81 arranged on the z-axis linear drive mechanism 7, a picking and placing mechanism 82, a distance measuring mechanism 83, and a hammering mechanism 84 arranged on the bracket 81; the picking and placing mechanism 82 is located on one side of the distance measuring mechanism 83, and the hammering mechanism 84 is located above the picking and placing mechanism 82. The picking and placing mechanism 82 is used to grasp the fixing member 9 and place the fixing member 9 on the vertical clamping plate. The distance measuring mechanism 83 is used to detect the distance between the installation gripper and the side surface of the vertical clamping plate; the hammering mechanism 84 is used to hammer the fixing member 9 to make the fixing member 9 closely combine with the vertical clamping plate; the picking and placing mechanism 82, the distance measuring mechanism 83, and the hammering mechanism 84 are all electrically connected to the control system. The gripper assembly 8 moves towards the direction close to the outer side surface of the vertical clamping plate 14. When the distance measuring mechanism 3 senses that the distance from the outer side surface of the vertical clamping plate 14 is equal to the set distance, the gripper assembly 8 stops moving towards the outer side surface of the vertical clamping plate 14. At this time, the fixing member is directly above the vertical clamping plate 14, and then the gripper assembly slowly moves downward to accurately engage the lower notch of the fixing member with the top of the vertical clamping plate 14. Subsequently, the picking and placing mechanism 82 releases the fixing member 9. Finally, the position of the hammering mechanism 84 is adjusted so that the hammering mechanism 84 is directly above the fixing member 9, and the hammering mechanism 84 hammers the fixing member 9 to make the fixing member 9 closely combine with the vertical clamping plate 14, ensuring that the placement position of the fixing member 9 is accurate and there will be no tilting.

[0031] In this embodiment, the bracket 81 is an L-shaped plate, and the L-shaped plate includes a bottom plate 811 and a vertical plate 812 perpendicular to the bottom plate. By setting the bracket 81 in an L-shaped structure, it can be better connected to the z-axis linear drive mechanism 7. The z-axis linear drive mechanism 7 is a linear module. The vertical plate is connected to the linear module by screws, and the slide of the linear module is fixedly connected to the y-axis carriage 5.

[0032] In this embodiment, the picking and placing mechanism 82 includes an electromagnet arranged on the bottom plate. The fixing member 9 is made of iron. After the electromagnet is energized, it can magnetically attract the bottom plate portion 91 of the fixing member 9, and releases the fixing member 9 when powered off. The picking and placing is reliable and convenient to operate.

[0033] Furthermore, the bottom surface of the electromagnet is a rectangular plane. By setting it like this, on the one hand, the bottom surface of the electromagnet can better fit the bottom plate portion 91 of the fixing member 9, improving the stability of picking and placing. On the other hand, it can increase the effective magnetic attraction area and obtain a greater magnetic attraction force.

[0034] Specifically, the hammering mechanism 84 includes a cylinder 841 fixedly arranged on the vertical plate 812 and vertically downward, and a hammer head 842 arranged at the end of the piston rod of the cylinder 841. During hammering, the hammer head 842 is located directly above the fixing member 9, and the cylinder 841 drives the hammer head 842 to move downward, causing the hammer head 842 to hammer the fixing member 9, not only making the fixing member 9 more tightly combined with the vertical clamping plate 14 to prevent the fixing member 9 from loosening, but also correcting the problem of the tilting placement of the fixing member 9, ensuring that the bottom film portion 91 of the fixing member 9 can be flat against the top surface of the vertical clamping plate 14, so that the next film roll's vertical clamping plate 14 can be stably placed on the fixing member 9.

[0035] Further, the hammer head 842 includes a horizontally arranged hammer plate and a hammer block arranged at the bottom of the hammer plate. The hammer block is arranged at the center of the bottom of the hammer plate, and the hammer plate is fixedly connected to the end of the piston rod of the cylinder 841. The hammer block is used to hammer the bottom film portion 91 of the fixing member 9, while the hammer plate presses the vertical film portion 92 of the fixing member 9 to prevent the fixing member 9 from jumping during hammering and ensure the tight connection between the fixing member 9 and the vertical clamping plate.

[0036] Preferably, the distance measuring mechanism 83 includes a support arm 831 vertically arranged at the bottom of the bottom plate and a distance measuring probe 832 arranged on the support arm 831. The distance measuring probe 832 is a laser distance sensor, and the laser distance sensor is sensitive and reliable in measuring the distance from the outer side surface of the vertical clamping plate.

[0037] In this embodiment, the frame 1 includes two symmetrically arranged upright frames 11. The film roll placing station 12 is arranged between the two upright frames 11. The two upright frames 11 are horizontally connected by an x-axis sliding frame 3. The y-axis linear driving mechanism 6 is a lead screw driving mechanism. Of course, the y-axis linear driving mechanism 6 being a lead screw driving mechanism can also be a pneumatic push rod, an electric push rod, a hydraulic push rod, a linear module, a linear actuator, etc., and its main effect is to provide the output end of linear motion. The x-axis linear driving mechanism 4 and the z-axis linear driving mechanism 7 are both linear modules. Of course, the x-axis linear driving mechanism 4 and the z-axis linear driving mechanism 7 can also be a pneumatic push rod, an electric push rod, a hydraulic push rod, a lead screw mechanism, etc., and its main effect is to provide the output end of linear motion.

[0038] See Figure 6 As shown, during palletizing, the first film roll is first placed on the wooden pallet 17. The first film roll is used as the lower layer film roll at this time. Subsequently, the fixing member 9 is placed on the top of the lower vertical clamping plate, and two turning pieces are clamped on the lower vertical clamping plate. The bottom surface of the bottom film portion is closely attached to the top surface of the lower vertical clamping plate. Then, the second film roll is palletized on the first film roll, and the upper vertical clamping plate is palletized on the lower vertical clamping plate. At this time, the bottom of the upper vertical clamping plate is embedded between the two vertical film portions, thereby positioning the upper vertical clamping plate and ensuring the neat palletizing of the film rolls.
