But particularly preferably be application preferably automatic operating extraction element and in conjunction with a handle apparatus.For example, claim more changing jobs of member during a rotation in conjunction with a handle apparatus, industrial machine hand for example, executor or a linear unit are realized, wherein on handle apparatus, settle two extraction elements that are synchronized with the movement, so that because shape is harmonious respectively should rotate symmetrical member and admit securely distolateral.

Wherein the symmetrical member of this rotation has corresponding opening on two ends and in the zone of the cylinder body of roll or the cylinder shaft shoulder or cylindrical journal, and preferably boring is so that realize dismountable, that shape is harmonious being connected with extraction element.

[embodiment]

At length set forth the present invention by an embodiment.Schematically show in the accompanying drawings:

Fig. 1 shows a manually operated extraction element (front view);

Fig. 2 shows an extraction element according to Fig. 1 (side view);

Fig. 3 shows an extraction element of operating automatically;

One is installed in the supporting arrangement the symmetrical member of rotation and exercisable extraction element mainly comprises in order to change one: a spheroid carrying sleeve 1, it prevents from supporting at least one on circumference with getting loose, best a plurality of spheroids 2.This spheroid 2 preferably is positioned in the circumferential plane and is projected into outside the circumference of this spheroid carrying sleeve 1 or can be pulled back down to the inside of this circumference.In addition, this extraction element have an operating means 4 of on this spheroid carrying sleeve 1, settling and by one in this spheroid carrying sleeve 1 inside movably pin 10 be in function with each spheroid 2 and be connected.This rotational symmetric member, preferably a cylinder or a barrel have an opening that becomes capwise with the member rotation on each end face, and hole for example is so that shape is contained in this extraction element with being harmonious.

Be used for manual organization plan at one, this spheroid carrying sleeve 1 is connected with a cradle head 3 of running through this spheroid carrying sleeve 1 on upper lateral ground, this joint 3 have one the support 5 of both sides and one (being parallel to cradle head 3) transverse to its (5) handle 6 (Fig. 1) setting and that be connected with this support 5.

This external spheroid carrying sleeve l goes up and settles an operating means 4, but it is manually actuated and is in function with this spheroid 2 by a pin 10 that moves at spheroid carrying sleeve 1 inside straight line and is connected.Its further structure will be described in detail in the embodiment of Fig. 3.Shown that by Fig. 1 and 2 each support 5 has one and settle the bent edge 7 of the extruding that is bent in following edge regions.This pushes bent edge 7 part as extraction element when changing this rotational symmetric member and can be placed in the upper side of a supporting structure and help a rotational symmetric member, preferably the replacing process of the craft of a cylinders of printing press or a printing machine roller.

Carry the further scheme that sleeve 1 is represented as Fig. 1 structure according to this spheroid of Fig. 3, wherein, this operating means 4 is automations, for example can be electronic, pneumatic or the hydraulic way actuating.Preferably, this actuating is to realize by a CCU of this printing machine.This spheroid carrying sleeve 1 has a conveyance conduit 8 that is used for the actuating of operating means 4, and it can pneumatically apply effect in the present embodiment.

But the pin 10 that moves at straight line of positioned inside of spheroid carrying sleeve 1.In upper area, this pin 10 with preferably can pneumatically-operated operating means 4 be in function and be connected.This pin 10 has (be preferably taper shrink) empty recessed meander sections 11 near spheroid 2 in lower area.Preferably the centre and to the zone on top, settled a power apparatus 9, it acts on this operating means 4.Preferably this power apparatus 9 is a compression spring that relative pin 10 centerings are settled, and it is bearing in the inside of this spheroid carrying sleeve 1.This pin 10 end thereon is connected for function with operating means 4.A upper member 12 is settled in the position regularly in opposite at operating means 4 on spheroid carrying sleeve 1.Operating means 4 and upper member 12 preferably have hermetically-sealed construction 13 and 14, and they live the bore seal that spheroid carries sleeve 1.This conveyance conduit 8 is passed in the zone that is formed by operating means 4 and upper member 12 of inner chamber of spheroid carrying sleeve 1, and therefore, the energy that is transfused to for example pressure air just acts on the operating means 4.Set a sensor 15 for upper member 12, it is connected with a CCU of printing machine with the circuit technology, and the position when a terminal location of this (having pin 10) operating means 4 of mensuration at least.Preferably this terminal location can be measured, and promptly this pin 10 is fixed on spheroid 2 from the position that the circumference of spheroid carrying sleeve 1 is given prominence to.

The mode of action of this extraction element, particularly the mode of action of spheroid carrying sleeve 1 is as follows: reset condition is that this spheroid 2 is outstanding from the circumference of spheroid carrying sleeve 1.This power apparatus 9 that is set to compression spring acts on operating means 4 and the pin 10 for this reason, and this pin 10 is expressed to spheroid 2 beyond the circumference of this spheroid carrying sleeve 1 with preventing to get loose.Thereby this spheroid 2 is located on this columned pin 10.

If a rotational symmetric member, when for example a printing machine roller should be replaced, then this operating means 4 by manually or automation ground (pneumatic, hydraulic pressure or electric) activate.By the operating means 4 that activated, spheroid carrying sleeve 1 inner moving, therefore, this annular space 11 just can be positioned in the height of spheroid 2 this pin 10 point-blank.The power effect of this power apparatus 9 (saying with regard to its effect) has then been eliminated by operating means 4.At this moment, spheroid 2 is just withdrawn from circumference.

If this spheroid carrying sleeve 1 is pushed in the opening of a symmetrical member of rotation, then spheroid 2 can return back in the space of annular space 11 equally by the wall portion of this opening.If arrived terminal location, then operating means 4 is placed in off working state, thus power apparatus 9 unloadings, and pin 10 is moved back on the home position of having described.When pin 10 motions, the annular space 11 that spheroid 2 tilts by this taper is raised on the columniform pin 10 and outwards extruding.Spheroid 2 just self is braked ground between the opening of pin 10 and arrangement in spheroid carrying sleeve 1.

Using under the handle apparatus situation, settled two extraction elements therein, their operating means can activate synchronously.This extraction element is so arranged, that is, this member that will be replaced can form with extraction element securely at distolateral opening with it and removably connect.For this reason in each extraction element this spheroid carrying sleeve 1 all shape be bonded in this opening that rotates symmetrical member with being harmonious, and the free bearing neutralization that this member is transported in a printing unit or inking device is placed on the there.

As an alternative, a rotational symmetric member also can manually removably connect with each extraction element by each spheroid carrying sleeve 1 distolateral, and can for example is transported to a stored position and can be placed on the there by one or more operators.For this reason, operator grasps handle 6 and drive operating means 4.At spheroid carrying sleeve 1 with rotate and form between the respective openings in the symmetrical member after shape is harmonious, this member just can extract from supporting structure.Wherein, this handle 6 can replace in cradle head 3, in order that the symmetrical member of this rotation can more easily extract from supporting structure under the prerequisite of utilizing the bent edge 7 of extruding.

After rotational symmetric member is put down, just can one other rotation symmetry member be installed identically by the extraction element structure.

Have a taper or crooked importing supplementary structure 16 in order better spheroid to be carried in the opening of attaching troops to a unit that sleeve 1 imports to the symmetrical member of a rotation this sleeve 1 distolateral.
