Problems solved by technology

Folds that are not made along the creases cause defects and thus cause the sheet to be rejected
[0008] It may happen that one or more of the pressure-applying wheels are no longer correctly oriented due to possible assembly defects in the wheels or due to defects in the arrangement which can interfere with prolonged use of the machine

Embodiment Construction

[0033] initial reference figure 1 and figure 2 , Reference numeral 10 denotes the entire wheel pressing device comprising a plurality of equally spaced idle wheels 11 (or rollers) arranged in a row aligned with the direction defined herein as the longitudinal direction. In this context, terms and expressions denoting direction and orientation such as "longitudinal" and "transversal", "front" and "rear" must refer to The advancing direction F followed by the sheet D of cardboard in the machine is explained. By way of example only, the Figure 10 A part of a folding-gluing machine to which a pressing device 10 with wheels can be applied is shown in .

[0034] The pressing device 10 may comprise a longitudinal support bar 12 on a belt conveyor system 13 ( figure 1 ) or motor driven roller conveyor system 14 ( figure 2 ) on the machine.

[0035] In the example shown here, the support bar 12 supports a plurality of rods 15 which are mounted in an elastically oscillating man...

Abstract

The present invention provides a folding-gluing machine for making cardboard boxes, comprising: a conveyor system with motor-driven belts or rollers adapted to advance the cardboard sheets in a specified direction; a plurality of wheel pressing devices, Arranged above the conveyor system, each wheel pressing device comprises: a plurality of equally spaced idler pulleys arranged in a row aligned in a designated direction; a plurality of parallel transverse pins, each pin adapted to support the corresponding idler pulley, each pin defines a transverse axis that is generally horizontal and perpendicular to a given direction, each idler gear includes a rolling bearing supported by a respective one of the pins and has a rotatable bearing outer ring; a plurality of elastic elements for moving each idler gear The belt is guided towards the conveyor system, each wheel pressing device comprising, for each idler, a spherical or annular surface inserted radially between the corresponding pin and the outer ring of the bearing so as to allow the transverse axis defined by the transverse pin to differ from the transverse axis defined by the transverse pin. There is an angular misalignment between the axes of rotation defined by the bearing outer ring.

Description

technical field [0001] The present invention belongs to the paper technology sector and relates to folding-gluing machines for the manufacture of cardboard boxes. More specifically, the present invention relates to wheel pressing devices on folding-gluing machines. Background technique [0002] Folding-gluing machines are used not only to make cartons of the conventional (or "linear") type but also of the type with an automatic bottom (also known as "crash-lock" boxes). [0003] As is well known, folding-gluing machines comprise a conveyor system for conveying the boxes, starting from the sheet supply, to the entry or upstream end of the machine, and up to the last or output station. The conveyor system may have motor driven rollers or belts. Roller conveyor systems provide a variety of motor-driven, rubber-coated transverse rollers; belt conveyor systems provide a longitudinally extending series of transversely spaced motor-driven parallel belts that circulate in parallel...
