摘要:
A system for transferring supports for objects which can be stacked and unstacked between a conveyor and a machine for printing the objects, characterized in that it includes: a mobile transfer table which has two locations each adapted to receive an object support and which is adapted to occupy a plurality of positions, first drive elements adapted to drive the transfer table vertically up and down, and second drive elements adapted to advance or withdraw the transfer table horizontally and simultaneously to transfer a support containing objects and an empty support or to withdraw the empty transfer table to a position awaiting a new support.

A squeegee head includes a squeegee carried by a squeegee-holder carried by a support and whose inclination on the support is adjustable by rotation about a pivot axis parallel to the lengthwise direction of the squeegee. The squeegee-holder pivot axis is substantially coplanar with the free edge of the squeegee. The squeegee heads finds a specific application in silkscreen printing machines.
摘要:
A printing assembly for a printing machine comprises a drum mounted for rotary movement about an axis and supporting a plurality of object holders parallel to the drum axis and uniformly circumferentially spaced around the axis. A drum drive imparts continuous rotary movement. A printing station at the periphery of drum for printing successive objects in the course of displacement by the printing station. The printing station is carried by a beam and includes a screen and squeegee. A beam drive is synchronized with the drum drive and imparts arcuate reciprocating movement to the beam about the axis such that the printing station tracks movement of an object at the printing station. The screen is disposed substantially parallel to the axis and mounted for tangential movement to the drum and the object at the printing station. A screen drive imparts rectilinear reciprocating movement to the screen relative to the beam in synchronism with beam movement.
摘要:
A printing machine suitable for printing objects with an oblong or a circular transverse cross-section includes a fixed printing shaft. An object to be printed is rotated about the printing shaft in contact with a flat printing plate or the like carried by a mobile assembly. The distance between the printing shaft and the printing plate or the like is corrected automatically. A drive shaft rotates the object to be printed through a transmission system which provides at least two transmission ratios.

In this printing machine, which is of the type comprising a horizontal printing station and, in vertical alignment with the latter, an exchange station, there are two transfer arms which are disposed at 90.degree. relative to each other, one on each side of a rotation axis inclined at 45.degree. which is common to them, in a plane containing the latter, and which occupy alternately a vertical position at the exchange station and a horizontal position at the printing station, and the holding means equipping each of these transfer arms for grasping an object to be printed comprises at least one clamp the two branches of which are each provided at their free end with a jaw adapted to encircle at least partially, in conjunction with the jaw of the other one, an object of this kind.
摘要:
An assembly (1) of at least one object (5) having an outer surface (12) substantially of revolution around an axis of revolution (Δ) and a machine (10) for printing the object, the machine including: at least four printing stations (16, 18, 20, 22) including at least two inkjet printheads, each printhead defining a median plane, the median planes intercepting the outer surface along two impact axes, respectively, seen from an opening angle from the axis of revolution; a conveying system (35) including at least one object carrier (40) and suitable for moving the object carrier relative to the printing stations sequentially in at least four printing positions, the object carrier being suitable for rotating the object around the axis of revolution; and a controller. In each of the printing positions: the two printheads are offset relative to one another along the axis of revolution; the control system is configured so that said two printheads print the object during at least one printing period; and the median planes form an angle strictly smaller than the opening angle between them.
摘要:
An improved ink jet printing machine (10) having an object loading means (30), capable of placing an object (1) in a first standby position on a first support (11) of the machine; a pretreatment station (40), including a first object holder (50) capable of: gripping an object (1) in the first standby position; bringing it into a pretreatment position in order to allow a pretreatment device (41) to perform a pre-treatment process on the said object; and, upon conclusion of the pretreatment, bringing it into a second standby position on a second support (12) of the machine; a printing station (60), including a second object holder (70) capable of: gripping an object in the second standby position; bringing it into a printing position in order to allow an inkjet type printing device to print the desired graphic on the said object; and, upon conclusion of the printing process, transferring it to an unloading means (80).
