Abstract

A toolpack arrangement for a can bodymaker having a frame. The toolpack includes a toolpack having a number of forming dies and an adjustment arrangement. The adjustment includes a number of adjustment mechanisms coupled between the toolpack and the frame, each adjustment mechanism being dynamically adjustable so as to selectively adjust the positioning of the toolpack with regard to the frame and/or a ram body of the can bodymaker as the ram body passes within the toolpack during normal can body making operations of the can bodymaker.

First claim

What is claimed is:

1 . A toolpack arrangement for a can bodymaker having a frame, the toolpack arrangement comprising:
a toolpack having a number of forming dies; and an adjustment arrangement comprising a number of adjustment mechanisms structured to be coupled between the toolpack and the frame, each adjustment mechanism being structured to dynamically selectively adjust the positioning of the toolpack with regard to the frame and/or a ram body of the can bodymaker as the ram body passes within the toolpack during normal can body making operations of the can bodymaker.

2 . The toolpack arrangement of claim 1 , wherein the adjustment arrangement further comprises a controller in communication with each adjustment mechanism of the number of adjustment mechanisms, wherein the controller is structured to selectively control each adjustment carried out by the number of adjustment mechanisms.

3 . The toolpack arrangement of claim 2 , further comprising a sensing arrangement in communication with the controller, wherein the sensing arrangement includes a number of sensors structured to detect the position of a number of components of the bodymaker, and wherein the controller is structured to selectively control each adjustment of the adjustment arrangements based at least in part from input received from the number of sensors.

4 . The toolpack arrangement of claim 1 , wherein the number of adjustment mechanisms comprises a plurality of adjustment mechanisms.

5 . The toolpack arrangement of claim 1 , further comprising a cradle supporting the toolpack, wherein the number of adjustment mechanisms are coupled to the toolpack via the cradle.

6 . The toolpack arrangement of claim 1 , wherein the number of adjustment mechanisms are driven by one or more of a mechanical, pneumatic, electrical and/or a hydraulic means.

7 . The toolpack arrangement of claim 4 , wherein each adjustment mechanism of the plurality of adjustment mechanisms are driven by one or more of a mechanical, pneumatic, electrical and/or a hydraulic means.

8 . A can bodymaker for forming a plurality of can bodies, the can bodymaker comprising:
a frame; a ram; an operating mechanism structured to provide a reciprocating motion to the ram; and a toolpack arrangement comprising:
a toolpack having a number of forming dies positioned such that the ram passes therewithin when provided with the reciprocating motion by the operating mechanism; and
an adjustment arrangement comprising a number of adjustment mechanisms coupled between the toolpack and the frame, each adjustment mechanism being dynamically adjustable so as to selectively adjust the positioning of the toolpack with regard to the frame and/or the ram as the ram passes within the toolpack during normal can body making operations of the can bodymaker.

9 . The can bodymaker of claim 8 , wherein the adjustment arrangement further comprises a controller in communication with each adjustment mechanism of the number of adjustment mechanisms, wherein the controller is structured to selectively control each adjustment carried out by the number of adjustment mechanisms.

10 . The can bodymaker of claim 9 , wherein the adjustment arrangement further comprises a sensing arrangement in communication with the controller, wherein the sensing arrangement includes a number of sensors structured to detect the position of a number of components of the bodymaker, and wherein the controller is structured to selectively control each adjustment carried out by the number of adjustment mechanisms based at least in part from input received from the number of sensors.

11 . The can bodymaker of claim 8 , wherein the number of adjustment mechanisms comprises a plurality of adjustment mechanisms.

12 . The can bodymaker of claim 8 , further comprising a cradle supporting the toolpack, wherein the number of adjustment mechanisms are coupled to the toolpack via the cradle.

13 . The can bodymaker of claim 8 , wherein the number of adjustment mechanisms are driven by one or more of a mechanical, pneumatic, electrical and/or a hydraulic means.

14 . The can bodymaker of claim 11 , wherein each adjustment mechanism of the plurality of adjustment mechanisms are driven by one or more of a mechanical, pneumatic, electrical and/or a hydraulic means.
