Embodiment

Embodiment one

Referring to Fig. 1, the Shaft drawer includes moving member 1, and moving member 1 is slidably connected with guide rail 3, and guide rail 3 is fixed on crane 4 On, crane 4 is slidably connected with frame 5.By the motor on crane 4, cylinder or the edge of Driven by Hydraulic Cylinder moving member 1 Guide rail 3 to slide, moving horizontally for moving member 1 is realized with this.Driven by the motor in frame 5, cylinder or hydraulic cylinder Dynamic crane 4 is lifted, and moving up and down for moving member 1 is realized with this.Slip of the moving member 1 along guide rail 3, and crane 4 Lifting, control is coordinated by the electric-control system of Shaft drawer.

Referring also to Fig. 1, Fig. 2, the electromagnet 2 moved together with moving member 1 is fixed with the end of moving member 1, electricity Magnet 2 has a magnetic face 7.As shown in figure 3, when moving member 1 with motor magnet 2 close to the Scroll 9 of rewinding product 8 when, The magnetic face 7 of electromagnet 2 can encounter and hold the Scroll 9 of rewinding product.When moving member 1 with motor magnet 2 away from rewinding During the Scroll 9 of product 8, the moving direction of moving member 1 parallel to the Scroll 9 of rewinding product axis, in this way, by electromagnetism Iron 2 extracts Scroll 9 out to the suction of Scroll 9 from rewinding product 8.

, can also be as shown in figure 4, electromagnet 2 to be fixed on to the side of moving member 1, Er Feigu as another embodiment It is scheduled on the end face of moving member 1.Magnetic face 7 is not limited to plane, can be curved surface, such as concave surface.In figure 3, rewinding product 8 is by another Outer mechanism is fixed and transfixion, or fixed by the deadweight of rewinding product 8.

As preferred forms, the size of magnetic face 7 in the vertical direction, more than moving member 1 relative to rewinding product 8 The deviation range in the height direction of Scroll 9.That is, as shown in figure 5, due to mechanism kinematic error, or rewinding product 8 The factor such as diameter change, cause moving member 1 to have certain skew in the height direction relative to the Scroll 9 of rewinding product 8 Scope H, then, the size L of magnetic face 7 in the vertical direction should be greater than deviation range H.In this way, even if because mechanism kinematic Error, or the diameter of rewinding product 8 change, and cause moving member 1 relative to the Scroll 9 of rewinding product 8 in height side Shift upwards, as long as moving moving member 1, the magnetic of electromagnet 2 along the axis direction of rewinding product 8 towards rewinding product 8 Suction face 7 just can necessarily touch the Scroll 9 of rewinding product 8, thus be produced without accurately control moving member 1 relative to rewinding The position of product 8 in the height direction, the control system of Shaft drawer can accomplish most simple, it might even be possible to save the lifting shown in Fig. 1 The drive mechanism of frame 4 and correlation, 1 need of moving member move horizontally.

In another embodiment, as shown in fig. 6, being fixed with multiple electromagnet 2 on moving member 1, the plurality of edge of electromagnet 2 Short transverse arrangement, the size N that the magnetic face 7 of the plurality of electromagnet 2 is included in the height direction, more than the phase of moving member 1 For the deviation range H in the height direction of Scroll 9 of rewinding product 8, and the gap M between adjacent electromagnet be less than it is multiple Roll up the diameter D of the Scroll 9 of product 8.In this way, even if because mechanism kinematic error, or the diameter of rewinding product 8 become Change, cause moving member 1 to be shifted in the height direction relative to the Scroll 9 of rewinding product 8, as long as along rewinding product 8 Axis direction towards rewinding product 8 move moving member 1, also can at least one electromagnet 2 magnetic face 7 touch rewinding production The Scroll 9 of product 8, thus without accurately controlling position of the moving member 1 relative to rewinding product 8 in the height direction, pull out axle The control system of device can accomplish most simple, it might even be possible to save the drive mechanism of the crane 4 and correlation shown in Fig. 1, moving member 1 It need to only move horizontally.

It should be noted that the end face that the size in the magnetic face 7 of electromagnet 2 can also be equal to or less than Scroll 9 is straight Footpath.In this case it is necessary to the magnetic face 7 of electromagnet 2 is accurately controlled with the relative position relation of Scroll 9.For example, it is directed to The rewinding product of different-diameter, by electric-control systems such as encoders, the end face center of the Scroll of rewinding product is controlled to be maintained at On one constant vertical line, then control moving member 1 to be first moved to corresponding height and move horizontally again, until electromagnet 2 Magnetic face 7 and the end contact of Scroll 9, thus can accurately control the magnetic face 7 of electromagnet 2 and the Scroll of rewinding product 9 relative position relation.

Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed, But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The scope of protection of the utility model.
