The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The utility model provides a kind of automatic discharge unit, as shown in Figures 1 and 2, two supports 1 that comprise vertical setting, close lower position between two supports 1 is connected with cross sill 13, place, cross sill 13 centers is equipped with discharging platform lift cylinder 2, the piston end of discharging platform lift cylinder 2 is equipped with unloading rack platform 4, unloading rack platform 4 lower surface places are provided with unloading rack rotary cylinder 3, the top of support 1 is provided with entablatrance 14, entablatrance 14 is provided with the unloading rack 19 that can move along entablatrance 14, be connected with horizontal rack 8 on the unloading rack 19, entablatrance 14 also is provided with the horizontal gear 15 that matches with horizontal rack 8, horizontal gear 15 drives by parallel motion motor 9, horizontal rack 8 two ends are connected with 2 symmetrically arranged lift cylinders 6 respectively, the piston end of 4 lift cylinders 6 is provided with hook 11 and hook cylinder 12, and entablatrance 14 is provided with limit switch I5 near an end place, and entablatrance 14 is provided with limit switch II10 near other end place.Wherein 4 lift cylinders 6 are provided with lifter rack 7 along its prolonging direction, and the lifter wheel 16 that matches with lifter rack 7 is installed on the entablatrance 14.Another root in the end that is positioned at entablatrance 14 in two supports 1, two supports 1 is positioned at the other end place near entablatrance 14.

Principle of work of the present utility model is, one be rolled into the product material and cut end after, equipment is in stopped status, press " discharging " button, back rolling swing arm 17, preceding rolling swing arm 18 is raised up to vertical position automatically under the effect of cylinder, expect that then the withdrawal of shaft locking cylinder is thrown off the material axle; This moment, discharging platform 4 began to rise, hook 11 is opened, lift cylinder 6 beginning drop to synchronously stretch out the most the next, lift cylinder bottom magnetic switch is connected, hook 11 is hung and is closed action, magnetic switch detects, confirm that four hooks 11 hang up properly two material axles, four lift cylinders 6 rise to the position, top synchronously automatically, lift cylinder 6 top magnetic switch detect and put in place, unloading rack 19 begins to move right, detect the limit on the right-right-hand limit position near limit switch I5, unloading rack 19 stops, lift cylinder 6 beginnings simultaneously drop to synchronously stretches out the most the nextly, and lift cylinder 6 bottom magnetic switch detect and put in place, and hook 11 was opened time-delay after 2 seconds, lift cylinder 6 rises to the position, top automatically synchronously, lift cylinder 6 top magnetic switch are connected, and unloading rack 19 begins to be moved to the left to left-limit position (being the discharging reference position), controls it near limit switch II10 and stops; Simultaneously discharging platform 4 drops to initial position, and revolves and turn 90 degrees, and this moment, once complete automatic discharging action was finished.

Working process of the present utility model is:

1 second time spent is risen in the preceding rolling swing arm 18 of a, slitting paper machine and back rolling swing arm 17;

B, four lift cylinders 6 are displaced downwardly to the bottom synchronously, and about 6 seconds of time spent, discharging platform 4 rises to the position, top according to coil diameter simultaneously;

C, hook 11 tangle the material axle, and programming control stopped 1 second, hang up properly fully to guarantee the material axle;

D, four lift cylinders 6 rise to position, top, about 6 seconds of time spent synchronously;

E, unloading rack 19 moved to left to finished product frame top, about 15 seconds of time spent;

F, four lift cylinders 6 fall to bottom, about 6 seconds of time spent;

G, hook 11 disengagement programs force to stop 1 second;

H, lift cylinder 6 rise to about 6 seconds of top, and simultaneously discharging platform 4 revolves and turn 90 degrees and descend;

I, unloading rack 19 move to right and stop to top, rolling position, and discharge process finishes.

By statistics, a discharging cycle was approximately about 42 seconds, prepared two immobilized spindles simultaneously, shut down to unload from full volume to be rolled onto the Scroll that new tube core is housed and to be loaded on the machine, was reduced to non-cutting time in 10 seconds.Equipment can normal operation, and the discharging action all automatically, need not to carry out M/C again.Shorten waiting time of machine halt greatly, reduced labour intensity and discharging danger simultaneously.

This device is controlled each step logical action of automatic discharging by the C200H-CPU44 of OMRON, the lifting of forward and backward material volume swing arm, locking and the disengagement of material axle, the folding of hook, the lifting of unloading rack and rotation, whether the lifting of material volume is all finished by the solenoid control cylinder, and detect action by magnetic switch and put in place; The parallel motion of unloading rack passes through motor transmission sway on horizontal rack, and spacing by detecting near switch; Tight logic control and reliable Detection means have guaranteed finishing smoothly of discharging action.
