Abstract

A unit for feeding a sheet of material into a machine for the manufacture of packaging. The unit is provided with a frame with height adjustable support for the sheets (3) . The unit comprises two separate sets of continuous conveyors (4; 5) . The conveyors (4a, 4b; 5a, 5b) of the individual set are interconnected. At least one of the conveyor sets (4) is laterally (A) adjustable in order to align a single sheet of material with a main line (H) operative for the remaining part of the machine for the manufacture of packagings . In this way, greater reliability and also greater operation speed are obtained.

= . . 2 According to the invention, at least one set of interconnected conveyors may . . increase their sheet advancing velocity with respect to the sheet advancing velocity . of the second set of interconnected conveyors. This provides better adjustrnent possibilities.

.
Moreover, according to the invention, at least one set of interconnected conveyors may laterally move a packaging sheet aligned at its front edge. This ensures that the advanced sheets can be centred with respect to the subsequent machine for manufacturing of packagings in a very reliable manner.
. 14 . , . . Furthermore, according to the invention, the front conveyor, seen in advance i direction, of each conveyor set may comprise at least two rollers and a continous belt led around them. As a result an especially "good grip" of each conveyor set in the top sheet of said stack at any time, is obtained.

According to the invention, the continuous belt for the front conveyor . of each conveyor set may comprise of a comparatively thick belt portion, the end of which being connected to a comparatively thin belt portion, the end of said latter belt portion being connected to the beginning of the comparatively thick belt portion. In this way, when the top sheet of the stack of sheets has been advanced so far into the =

unit that "the thick belt portion" lies opposite the sheet, said sheet may be easily =
moved sideways by means of said thick belt portion, since the thick belt portion ~
exerts pressure on the sheet, in order to centre the sheet with respect to the subsequent machine for manufacturing of packagings.

= .

. Moreover, according to the invention, the front conveyor of each conveyor set may be provided with th.ree rollers, around which the corresponding continuous belt is led. Zn practice, this has also proved to be particularly practical.

Further, according to the invention, the two sets of conveyors may each be driven by ' its own servomotor operational at different angular velocities, thus permitting the two conveyor sets to be brought to run with exactly the same advancing velocity, Furthermore, according to the invention, each of the two conveyor sets may be driven by its own variable frequency motor thus achieving a very reliable operation o the unit.

Finally and according to the invention, the sheets for the packaging may be of corrugated cardboard, solid (thick) cardboard or plastics. In practice, it has been found that the unit can advance this type of packaging sheet in a particularly reliable way. ' .

Fig. 2 shows an embodiment of a un.it for feeding a sheet of material into a machine ~ for the manufacturing of a packaging I; the machine comprises a frame with a height adjustable support 2 for sheets of material3, as shown in Fig. 3. The sheet material is usually present in the form of a stack, as shown in Fig. 2. As shown in Fig. l, the unit possesses two separate sets 4 and 5 of continuous conveyors.
The conveyors 4a and 4b of the conveyor set 4 are interconnected. Similarly, the conveyors 5a and 5b of the conveyor set 5 are interconnected, ane conveyor set 4 of the conveyor sets 4, 5 is laterally adjustable; this means first and foremost that the conveyor set 4 or conveyor set 5 may conduct a lateral translational movement, cf.

1 o the double arrow A in Fig. 2--, in order to align the sheets of rnaterial advanced by means of this unit with a main line H operative for the remaining part of the machine for the manufacture of packagings l. Usually, the second conveyor set 5 is not laterally adjustable. .

The two separate sets of continuous conveyors 4 and 5 are usually mounted parallel + to each other and on top of said stack. At least one of the conveyor sets, e.g. the conveyor set 4, may increase its sheet a.dvancing velocity compared to the sheet advancing velocity obtainable by the second set 5 of the interconnected conveyors.
Thus, it is possible to align (i.e. turn) the sheet of material (on top of the sheet Zo stack) which is being advanced. Turning takes place in such a way that as a result the front edge of the sheet will be exactly perpendicular to the advance direction of the sheet The front conveyor 4a, 5a, seen in advance direction, of the conveyor set 4 and 5 may e.g. comprise two, three or more rollers' 12a, 12b and 13a, 13b, 13c, and a continuous belt 12',13' is led around each of these roller sets.

With respect to the continuous belt 12' or 13' for the front conveyor of each conveyor set 4 5, it may be made of a comparatively thick belt portion 12'a, the end 12'ae of which being connected to the beginning of a comparatively thin belt portion 12'b, the end 12'b0 of said latter belt portion being connected to the . ~ . - ~ ..... ~

5 Instead, the front conveyor 4a, 5a of each conveyor set 4, 5 may be provided with three rollers (cf. Fig. 1), around which the corresponding continuous belt 12', 13' is led, as shown in Fig. 2. Normally, the conveyor 4b, 5b, the "next in line" in each conveyor set 4 or 5, is only provided with two rollers, around which a continuous belt runs.
The two sets of ~conveyors 4, . 5 may be driven by their own servomotors (not shown), and each servomotor may operate at different angular velocities.

Optionally, each servomotor may be a variable frequency motor (not shown).
The invention may be modified in many ways without thereby deviating from its scope. Thus, each conveyor may consist of more than three rollers and a continuous belt led around them.
