US 2017/0057111 A1 · METHOD AND DEVICE FOR GUIDING A TOOL

Abstract

Method and device for guiding a tool (2) in a recurring application of a product (3) moved along an X-axis, wherein the tool (2) is mounted on the Z-carriage (12) of a cross guide and is moved therewith along the Z-axis standing perpendicular on the X-axis, wherein the Z-carriage (12) is mounted on the X-carriage (10) of the cross guide, the guide of which is mounted along the X-axis in a base plane (13), wherein the X-carriage (10) is driven with an X-drive, wherein the Z-carriage (12) is driven by a Z-drive, which is held stationary in the base plane (13) and has a traction means (17) driven by a first servo motor (8) provided for the drive of the Z-carriage, which is driven from the base plane (13) on the movable Z-carriage (12), wherein a movement of the Z-carriage (12) that is brought about by the movement of the X-carriage (10) and a motive force caused thereby on the traction means (17), is compensated when actuating the first servo motor (8) provided for the drive of the Z-carriage.

A method for guiding a tool (2) in a repetitive action on a product (3) moving along an X-axis, wherein the tool (2) is mounted on the Z-slide (12) of a cross guide and, therefore, is moved along the Z-axis disposed perpendicular to the X-axis, wherein the Z-slide (12) is mounted on the X-slide (10) of the cross guide, the guidance of which along the X-axis is mounted in a base plane (13),

wherein
the X-slide (10) is driven with a X-drive (7),
the Z-slide (12) is driven with a Z-drive (8), which is held in a stationary manner in the base plane (13) and has a belt (17) driven by a first servomotor (8) provided for the drive of the Z-slide, said belt being guided on the movable Z-slide (12) from out of the base plane (13), wherein a movement of the Z-slide (12) caused by movement of the X-slide (10) and a resultant tractive force on the belt (17) is compensated for in the control of the first servomotor (8) provided for the drive of the Z-slide.

A device for guiding a tool (2) in a repetitive action on a moving product (3), wherein the device comprises a cross guide, wherein the tool (2) is held on a Z-slide (12), the guidance of which defines the Z-axis of the cross guide, wherein the Z-slide (12) is movably held on an X-slide (10), the guidance of which defines the X-axis, which is perpendicular to the Z-axis, wherein the guidance along the X-axis is mounted in a base plane (13),

wherein
an X-drive is provided to drive the X-slide (10),
for the drive of the Z-slide (12), a Z-drive is held in the base plane in a stationary manner, said Z-drive comprising a belt (17) driven by a first servomotor (8) provided for the drive of the Z-slide, wherein the belt (17) is guided in a T-shaped path, which has an X-leg (18) and a Z-leg (19), wherein the X-leg (18) extends around two pulleys (8, 16) held in the base plane (13) and forms a top pull (24) and a bottom pull, wherein the top pull (24) branches via a first tension roller (20) and a second tension roller (20a) held on the Z-slide (12) into a loop (19) forming the Z-leg, said loop being guided around another redirection roller (21), which is held on the X-slide (10) at the end of the Z-section, wherein a compensation device is provided for controlling the first servomotor (8) provided for the drive of the Z-slide so as to compensate for a movement of the Z-slide (12) caused by a movement of the X-slide (10).
