Definitions

• the present invention relates to a device for centering sheet blanks on a blank stacker.
• the invention also relates to a blank stacker equipped with such a device.
• the blank stackers of this type are located in the cutting lines of sheet metal stamping workshops for motor vehicles.
• the sheet blanks must be perfectly centered on the stacker of the blanks.
• a device for centering sheet blanks on a stacker which comprises centering pins 1 movable in a direction D perpendicular to the stacking direction D1 blanks 2 on the stacker 3.
• This centering must be modified in case of modification of the sheet metal parts to be cut.
• One of the operators controls, by means of a remote control, the displacement of the centering pin 1 in the direction D.
• the other operator holds a strip 4 which he applies against the edge 2a of the blank 2 and the pin 1 to display the position of the blank 2 relative to the stacker, as shown in FIG.
• the object of the present invention is to overcome these disadvantages.
• a device for centering sheet blanks on a stacker of blanks comprising centering pins movable in a direction perpendicular to the stacking direction of the blanks on said stacker, characterized in that it comprises a member for controlling the position of a blank placed on said centering pins, comprising at least one magnet for fixing by magnetic attraction said member detachably on each of said centering pins and a blade intended to be positioned against the outer edge of the blank.
• the body for controlling the position of a blank thus replaces the strip which is handled by one of the two operators mentioned above.
• this member can be detachably attached to a centering pin, thanks to at least one magnet, makes it possible to economize this operator, so that the other operator who is responsible for controlling the movement of a pawn is enough to carry out all the operations.
• said member comprises a plastic body in which several magnets are embedded, this body having a surface intended to be applied on the centering pin, said magnets being located close to said surface .
• said surface of the body is complementary to the cylindrical lateral face of the pin.
• the blade intended to be positioned against the outer edge of the blank may be metallic.
• the blade protrudes on one side of said body and extends parallel to said surface.
• said body further comprises a gripping handle, which facilitates the handling of the device according to the invention by the single operator mentioned above.
• said handle is fixed on a face of said body opposite to the surface intended to be applied on the pin.
• the handle is in the shape of a square, one of the two branches of this bracket being secured to said body and the other leg extending parallel to said surface.
• the invention also relates to a blank stacker equipped with a device according to the invention.
• FIG. 3 is a plan view of the device according to the invention.
• FIG. 4 is a side view of the device, represented in FIG. 3, in position against a centering pin and the edge of a sheet blank,
• FIG. 5 is a sectional view along the plane V-V of Figure 4.
• the member 5 shown in FIGS. 3 to 5 replaces the strip 4, illustrated in FIG.
• the member 5 serves to control the position of the blank 2 placed on the centering pin 1.
• the member 5 comprises magnets 7 making it possible to fix the member 5 detachably on the centering pin 1 by magnetic attraction and a blade 8 intended to be positioned against the outer edge 2a of the blank 2, as shown in Figure 4.
• the member 5 comprises a body 6 made of plastic, such as polyamide, in which four magnets 7 are embedded.
• the body 6 has a surface 6a intended to be applied to the centering pin 1.
• the surface 6a of the body 6 is complementary to the cylindrical side face of the pin 1, as shown in FIG. 5, which makes it possible to guarantee a precise and reproducible geometric position of the member 5 with respect to the pin 1.
• the pin 1 is of course made of steel so that the magnets 7 housed in the body 6 can exert a magnetic attraction on the pin 1 and thus detachably fix the body 6 on the pin 1.
• the blade 8 is preferably metallic, protrudes on a face 6b of the body 6 and extends parallel to the cylindrical surface 6a of the body 6.
• FIG. 4 further shows that the body 6 comprises a gripping handle 9.
• This handle 9 is fixed on a face 6c of the body 6 opposite the surface 6a intended to be applied on the pin 1.
• the handle 9 is in the form of a square, one of the two branches of this bracket being secured to the body 6 and the other leg extending parallel to the surface 6a of the body 6.
• An operator controls the displacement of the centering pin 1 towards the edge 2a of the sheet blank 2.
• the member 5 is held fixed to the pin 1 thanks to the magnetic attraction exerted by the magnets 7.
