The coil sleeved on the expansion shaft of the coiler 1 is taken down and overturned by the material taking and overturning mechanism 3, and then placed on the material receiving assembly 6, the carrying mechanism 4 carries the coil on the material receiving assembly 6 to the discharge conveying line 2, the whole process is automated, the labor cost is saved, the production efficiency is greatly improved, the safety hidden danger is eliminated, and the full automation of the production, transfer, packaging and other flow operations of the metal strip coil is created. By arranging the material taking assembly 3c on the overturning assembly 3b, the overturning assembly 3b and the material taking assembly 3c are integrated, and the space utilization is improved. The coiler 1 and the discharge conveying line 2 are both prior art, and their specific structures will not be described in detail here.

[0032] As Figures 2-4As shown, the turnover assembly 3b includes a moving base 3b1 slidingly mounted on the base 3a, a turnover body 3b2 rotatably mounted at the right end of the moving base 3b1, a turnover oil cylinder 3b3 driving the turnover body 3b2 to rotate, a turnover in-place sensor 3b4 mounted at the right end of the moving base 3b1, and a first driving assembly 3b5 driving the moving base 3b1 to move laterally along the base 3a. The middle part of the turnover body 3b2 is mounted on the moving base 3b1 through bearing seats 3b6 respectively at both sides, the mounting end of the turnover oil cylinder 3b3 is hinged to the left end of the moving base 3b1, the output end is hinged to the bottom end of the turnover body 3b2, and the taking assembly 3c is mounted on the platform 8 protruding from the middle part of the turnover body 3b2. The first driving assembly 3b5 drives the moving base 3b1 to move along the base 3a towards the winding machine 1, and after reaching the position, the taking assembly 3c takes down the roll on the expansion shaft of the winding machine 1. The expansion shaft of the winding machine 1 retracts to disengage from the inner circle of the roll, the first driving assembly 3b5 drives the moving base 3b1 to move along the base 3a towards the discharge conveying line 2, and after reaching the position, the output end of the turnover oil cylinder 3b3 pushes the bottom end of the turnover body 3b2, the turnover body 3b2 rotates around the middle part until the roll is turned to a horizontal state, triggering the turnover in-place sensor 3b4, and the turnover oil cylinder 3b3 stops driving. Specifically, the moving base 3b1 is connected to the base 3a through guide rails and guide blocks at both sides, which is a prior art and will not be described in detail here.

[0033] As shown in Figure 3 The first driving assembly 3b5 includes a first moving motor 3b51 mounted in the middle part of the bottom surface of the moving base 3b1, a first gear 3b52 mounted at the output end of the first moving motor 3b51, and a first rack 3b53 mounted in the base 3a. The first gear 3b52 is engaged with the first rack 3b53, and the ends of the base 3a are provided with a moving in-place sensor 9 and a moving limit seat 10. The output end of the first moving motor 3b51 drives the first gear 3b52 to rotate, and the engagement of the first gear 3b52 with the first rack 3b53 forces the moving base 3b1 to move relative to the base 3a. The setting of the moving in-place sensor 9 limits the stroke of the moving base 3b1, ensuring the accuracy of the moving stroke of the moving base 3b1, and also serving as a signal for the next action; the setting of the moving limit seat 10 serves as a mechanical limit.

[0034] As shown in Figure 2As shown, the material taking assembly 3c includes a V-shaped frame 3c1, a plug rod 3c2 detachably mounted on the V-shaped frame 3c1, a material taking oil cylinder 3c3 driving the V-shaped frame 3c1 to move longitudinally, and a material roll sensing sensor 3c4 mounted on the top of the turnover body 3b2. The material taking oil cylinder 3c3 is mounted on the platform 8, and the output end thereof is connected with the bottom surface of the V-shaped frame 3c1. The first driving group 3b5 drives the moving base 3b1 to move along the machine base 3a towards the winding machine 1, and when in position, triggers the right end moving-in-position sensor 9 and the material roll sensing sensor 3c4. The first driving group 3b5 stops driving, and at the same time, the material taking oil cylinder 3c3 drives the V-shaped frame 3c1 to move upwards until the V-shaped frame 3c1 contacts the outer ring of the material roll and supports the material roll. After the expansion shaft of the winding machine 1 retracts and is separated from the inner ring of the material roll, the first driving group 3b5 drives the moving base 3b1 to move along the machine base 3a towards the material discharging conveying line 2, and when in position, triggers the left end moving-in-position sensor 9. The turnover assembly 3b turns over the material roll. The provision of the V-shaped frame 3c1 realizes stable support of the material roll, avoiding rolling of the material roll. The provision of the plug rod 3c2 prevents the material roll from falling or falling over during the movement of the moving base 3b1. Specifically, a plurality of rows of plug holes 19 are symmetrically provided on the two sides of the V-shaped frame 3c1, the adjacent plug holes 19 on the same side are in close contact, and the bottom of the plug rod 3c2 is inserted into the plug hole 19. By symmetrically providing a plurality of rows of plug holes 19 on the two sides of the V-shaped frame 3c1, the plug rod 3c2 can realize the limiting effect on material rolls of different thicknesses, and has wide versatility.

[0035] As shown in Figure 3 In order to ensure the stability of the longitudinal movement of the V-shaped frame 3c1, a slide rod 20 is symmetrically provided on the two sides of the material taking oil cylinder 3c3. The bottom end of the slide rod 20 is slidably provided in the platform 8, and the top end of the slide rod 20 is connected with the bottom surface of the V-shaped frame 3c1.

[0036] As shown in Figure 4 The material receiving assembly 6 includes a material receiving base 6a mounted on the middle of the left end of the machine base 3a, a material receiving oil cylinder 6b mounted on the material receiving base 6a, a material receiving platform 6c mounted on the output end of the material receiving oil cylinder 6b, a material receiving sensor 6d mounted on the material receiving platform 6c, and a pull rope encoder 6e mounted on the material receiving base 6a. Through the provision of the material receiving assembly 6, the handover of the turned-over material roll is realized, and at the same time, the empty material taking and turning mechanism 3 takes the next material roll, ensuring the production efficiency. The provision of the material receiving sensor 6d plays a role in material shortage alarm. When there is a material roll on the material receiving platform 6c, the material receiving sensor 6d can sense and perform normal handling. When the material roll on the material receiving platform 6c is removed, the material receiving sensor 6d will alarm or directly instruct the material taking and turning mechanism 3 to continue feeding, so as to achieve the function of automatic material replenishment, realize the flow production, and improve the production efficiency. The provision of the pull rope encoder 6e controls the movement stroke of the material receiving oil cylinder 6b to adapt to material rolls of different thicknesses.

After the material taking assembly 3c takes down the material roll on the expansion shaft of the winding machine 1, the first driving group 3b5 drives the moving base 3b1 to move along the machine base 3a to the direction of the discharging conveying line 2, and after reaching the position, the overturning assembly 3b overturns the material roll until the material roll is overturned to a horizontal state and triggers the overturning position sensor 3b4. At this time, the material roll is located directly above the receiving platform 6c, the plug rod 3c2 is removed, the receiving oil cylinder 6b drives the receiving platform 6c to move upward, the receiving plate 11 passes through the first avoiding groove 12 to lift the material roll, so that the material roll is separated from the overturning body 3b2, thereby completing the transfer of the material roll. The first driving group 3b5 drives the moving base 3b1 to move along the machine base 3a to the direction of the winding machine 1 to perform the material taking action of the next material roll.

The carrying oil cylinder 4a3 drives the suction assembly 4b to move downward by a predetermined stroke, the suction assembly 4b contacts and sucks the material roll on the receiving platform 6c, then the carrying oil cylinder 4a3 drives the suction assembly 4b to move upward to reset, the second driving group 4a4 drives the moving trolley 4a2 to move to the direction of the discharging conveying line 2, and stops when it moves to the position directly above the discharging conveying line 2 and triggers the position proximity switch, the carrying oil cylinder 4a3 drives the suction assembly 4b to move downward until the material roll contacts the discharging conveying line 2, then the suction assembly 4b no longer sucks the material roll, and the material roll is placed on the discharging conveying line 2, and the suction assembly 4b and the moving trolley 4a2 are reset to carry the next material roll. Specifically, both sides of the moving trolley 4a2 are connected with the carrying frame 4a1 through guide rails and guide blocks.

[0040] Similarly, in order to ensure the stability of the longitudinal movement of the suction assembly 4b, the two sides of the carrying oil cylinder 4a3 are also symmetrically provided with slide rods 20, the top ends of the slide rods 20 slide through the moving trolley 4a2, and the bottom ends of the slide rods 20 are connected with the suction assembly 4b.

When taking the coil, the carrying oil cylinder 4a3 drives the mounting plate 4b1 to move downward, thereby synchronously driving the vacuum chuck 4b3 to move downward, the vacuum chuck 4b3 is lifted by the coil after contacting the coil on the material receiving platform 9c, the shifting rod 4b2 shifts upward, so that the shifting inductor 15 senses the shifting induction plate 14, at this time the vacuum chuck 4b3 stops moving downward, the gas source group pumps air, and the vacuum chuck 4b3 sucks the coil; when discharging the coil, the carrying oil cylinder 4a3 drives the mounting plate 4b1 to move downward, thereby synchronously driving the vacuum chuck 4b3 to move downward, until the coil contacts the discharge conveying line 2, the vacuum chuck 4b3 is lifted by the coil, the shifting rod 4b2 shifts upward, so that the shifting inductor 15 senses the shifting induction plate 14, at this time the vacuum chuck 4b3 stops moving downward, the gas source group releases air, and the vacuum chuck 4b3 releases the coil.
