Abstract
In a process and apparatus for decorating a flat self-supporting article which is turned for decoration thereof on both sides, the article is firstly removed from a horizontal position in an article holder by being lifted by a first pivoting means and then pivoted into a vertical intermediate position from which the article is moved by a second pivoting means producing a pivoting movement of the article into a horizontal position with its previously upward surface facing downwardly. The article is then lowered into an article holder again.
Claims25
Apparatus for decorating a flat self-supporting article comprising
- an article holding means with a receiving means for an article,
- a turning means including first and second pivoting means, each of which comprises a suction means, the first pivoting means including a bar portion adapted to co-operate with the second pivoting means and with an opening in the article for alignment of the article, and
- means mounting the pivoting means movably between a first position operatively associated with a receiving means for the article and an intermediate position and pivotably for an article carried by the suction means of the respective pivoting means to be successively pivoted by the first and second pivoting means relative to the plane in which the article extends in a receiving means, the first and second pivoting means being arranged in mutually opposite relationship in the intermediate position in such a way that the article is transferred from the first pivoting means to the second pivoting means by suitable control of the suction means.
Apparatus for handling flat self-supporting articles, comprising
- an article holder including a plurality of article receivers for receiving and supporting an article in an initial position in which a first side of the article is presented,
- a first pivotable suction head for contacting an article in an article receiver on the first side of the article, the first pivotable suction head including at least one suction opening for engaging and holding the article bv suction for movement with the first pivotable suction head and an extendible member adapted to co-operate with an opening in the article for alignment thereof,
- a second pivotable suction head for contacting the article on a second side thereof remote from the first side, the second pivotable suction head cooperating with the extendible member and including at least one suction opening for engaging and holding the article by suction for movement with the second pivotable suction head,
- a driver for causing the first pivotable suction head to pivot and move the held article into an intermediate position and for causing the second pivotable suction head to pivot and move into a position to engage the second side of the article,
- a suction controller for removing the suction between the first pivotable suction head and the article after the article is engaged and held by the second pivotable suction head,
- the driver being operable to cause the second pivotable suction head to pivot and return the held article to the article receiver in a final position in which the second side of the article is presented.

Apparatus for turning over a flat article, comprising
- a first suction head for engaging a first side of an article disposed in an initial position in which the first side is presented and holding the article by suction, the first suction head including an extendible member adapted to co-operate with an opening in the article for alignment thereof,
- a second suction head cooperating with the extendible member for engaging a second side of the article remote from the first side and holding the article by suction,
- a driver for causing the first suction head to move the held article into an intermediate position and for causing the second suction head to move into a position to engage the second side of the article held by the first suction head.
- a suction controller for removing the suction between the first suction head and the article after the article is engaged and held by the second suction head,
- the driver being operable to cause the second suction head to place the held article in a final position in which the second side of the article is presented, the suction controller being operable to remove the suction between the second suction head and the article after the article is in the final position.

Apparatus for turning over a flat article, comprising
- a first suction head for engaging a first side of an article horizontally disposed in an initial position in which the first side faces upward and holding the article by suction, and including an extendible member adapted to co-operate with an opening in the article for alignment thereof,
- a second suction head cooperating with the extendible member for engaging a second side of the article remote from the first side and holding the article by suction,
- a driver for causing the first suction head to move the held article into an intermediate position and for causing the second suction head to move into a position to engage the second side of the article held by the first suction head,
- a suction controller for removing the suction between the first suction head and the article after the article is engaged and held by the second suction head,
- the driver being operable to cause the second suction head to place the held article in a horizontally disposed final position in which the second side of the article faces upward, the suction controller being operable to remove the suction between the second suction head and the article after the article is in the final position.
