Abstract
A steel rule cutting die apparatus is described for manufacturing a carton from a carton blank with self-cleaning punches for cutting small diameter holes in a carton blank and waste removal means being a channel member below the carton blank with an air flow with a partial vacuum in the channel member so that waste produced by the punches is removed.
Description
Steel Rule Cutting Die Apparatus This invention relates to steel-rule cutting and creasing die apparatus used in the production of paperboard folding cartons from carton blanks.
Modern production of paperboard folding cartons features in-line printing, die-cutting and waste stripping, allowing finished cartons to be processed from roll stock to finished cartons in one operation.
The stripping of integral waste is normally conducted post die-cutting and the minimum size of waste pieces is dictated by engineering of the equipment in use.
It is sometimes desired to cut small holes of 0.5 mm to 5.0 mm diameter in a paperboard blank. However, it was previously considered impossible to effectively cut and cleanly strip the blank.
Self-cleaning punches for this purpose are available but the difficulty has always been to remove waste which would, under normal circumstances in an in-line operation, litter the working area rendering it difficult to produce quality cartons efficiently.
It is an object of the present invention to provide apparatus with which it is possible to cut such small diameter holes in a carton blank wherein the above-mentioned difficulty is substantially obviated.
Accordingly, there is provided a steel rule and cutting die, one or more self-cleaning punches for cutting one or more holes in a carton blank, waste removal means for removing waste pieces after said cutting with a channel member below said carton blank, in use, and means for providing at least a partial vacuum in said channel member to draw said waste pieces away from said punches to a waste collection area.
An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings in which:
Figure 1 is a cross-sectional side view of the embodiment used in a steel rule cutting die for carton production;

An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings in which:
Figure 1 is a cross-sectional side view of the embodiment used in a steel rule cutting die for carton production;
- 2 -Figure 2 is a plan view of the arrangement in Figure 1 with the lid removed;
Figure 3 is a plan view of the pre-drilled lid;
Figure 4 is a diagrammatic representation of part of a Bobst-Champlain reciprocating die machine showing how the embodiment could be included, Figure 5 is a diagrammatic representation in plan view of a 6-up die incorporating an embodiment of the invention, and Figure 6 is a cross-section of part of the die of Figure 5 on the line VI - VI.
The same reference numerals are used throughout for like parts.
Referring to the Figures a standard steel creasing rule 2 (0.923+) is shown with cutting rules 3 (Figures 5 and 6). Nine standard self-cleaning punches 4 (0.937"
high) are provided as shown in Figures 1 and 2 to punch holes in a carton blank. These can be, for example, 0.5 to 5.0 mm diameter holes. They each have waste ejection orifices 6 and their orientation can be seen in Figure 2.
Ejected waste scraps, such as 8, are shown in Figures 1 and 2.
A channel member 10 is provided to receive the scraps 8 and a receiving air pocket is provided by placing a pocket lid 12 over, and thus closing, the top of the channel member 10, the lower limit thereof being the flat surface of the existing die board 11 which extends across the entire die.
A support frame 14 (Figures 1 and 2) is provided to support the channel member 10 and the pocket lid 12.
Air is passed through the channel member 10 through an air inlet portion 16, passes through the channel member collecting the scraps 8 and passes through an outlet portion 18 where at least a partial vacuum exists.
To create this partial vacuum and ensure that most, or all, of the scraps 8 are collected, a vacuum cleaner

- 3 -unit 20, such as a "SHOP-VAC*", is connected to the channel at outlet 18 and encloses a waste collection area. An air pocket is thus formed in the channel member to enhance the flow of scraps 8.
As mentioned above, the channel member 10 has a lid 12 (Figure 3) and this is adhered to the support frame shoulder 14 by means of double-sided adhesive tape (such as 15). The lid 12 is made of thin rigid material and is pre-drilled with holes 22 to fit over the heads of the punches 4 but, in use, they are above the waste ejection orifices 6.
The channel member inlet 16 is an air make-up 1/4"
channel routed into 1/16" die board 17 (Figure 2) and exiting the pocket via a bridge. Similarly, outlet 18 is a 1/4" channel routed into the die board 17 and connected to channel member 10 via a natural "bridge" creasing rule 2. A carton blank is, in use, positioned above lid 12.
In Figure 4 part of a Bobst-Champlain reciprocating die machine is diagrammatically illustrated with the upper chase or frame 24 pulled out from the upper bolster portion 26 on external support brackets 28.
The channel member 10 (Figure 1) is below the lower chase assembly and the outlet 18 emerges through a hole drilled in the chase by way of a 1/4" tube 30 to the vacuum cleaner unit 20.
Figures 5 and 6 show a traditional steel rule cutting and creasing die. This would generally be produced from maple plywood with slots cut by laser to accommodate the steel cutting and creasing rules.
A plurality of channel members 10 are shown in Figure 5 interconnected by a covered channel member 13 similar to the covered channel outlet portion 18. The channel member inlet 16 is also shown in Figure 5 vented *Trademark

- 4 -to the outside air and is a channel routed into the die board.
The entire die would, in use, be fitted into the steel frame 24 (Figure 4) with the die face downwards.
The die and the frame would be inserted into the cutter and the cutting action effected by reciprocation of the upper section of the cutter against the stationary bed with the stock being fed between the two sections as the machine reciprocates.
It will be understood that more than one tube 30, of appropriate size, will normally be provided dependent on the number of channel members 10.
In one constructed embodiment the apparatus allowed four cartons to be run in-line with a pattern of two sets of 9 x 1 mm holes clearly cut and stripped from 8 positions in a die forme.
Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of a limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
