Problems solved by technology

However, in contrast to the similar gear elements in the buffer conversion machines described above, the grippers generally cannot punch or stitch together the layers of sheet stock material passing through them due to the gaps between the grippers.

Embodiment Construction

[0025] Referring now to the attached drawings in detail, and first to Figure 1-9 , figure 1 Shown for the sheet material 22 ( image 3 ) into dunnage strip 24 ( Figure 13 ) of an exemplary compact dunnage conversion machine (ie, converter) 20. The converter 20 is part of a packaging system 26 which also includes figure 2 Adjustment bracket 40 is shown, to which the converter 20 can be mounted in a raised position.

[0026] figure 2 The bracket 40 shown in FIG. 2 includes a base 42 and a telescopically adjustable upright 44 to which the converter 20 can be secured. The base 42 includes wheels 46 so that the stand 40 can be easily moved. However, the base body 42 of the bracket 40 may have a different configuration, for example a clamp for mounting on a workbench.

[0027] now refer to Figure 9 , the converter 20 can be mounted on the bracket 40 by a pair of rotating guides 50 pivoted by a pivot 52 passing through the arms of a generally U-shaped bracket 54, the bas...

Abstract

A compact dunnage conversion machine includes a converging chute with a restricted inlet, a powered feed assembly with a sealed gearbox, a plurality of interchangeable power supplies, and a restricted outlet chute. The converter can convert a sheet stock material into dunnage for use in packaging one or more objects in a container. The restricted inlet and outlet make it more difficult for foreign objects to enter the converter and disrupt the conversion process. The sealed gearbox interposed between the driving elements of the feed assembly and an electric motor facilitates maintenance and repair of the feed assembly, while also protecting the gears therein. Finally, the power supplies provide electrical power to the motor and can include an electrical storage device, such as a battery, or an alternating-current-to-direct-current converter which is connectable to a source of electricity for supplying that electricity to the motor in an acceptable form.

Description

technical field [0001] The present invention relates generally to a dunnage converting machine for converting raw materials into dunnage products and improvements thereto. Background technique [0002] Dunnage converting machines, also called converters, generally convert sheet stock into a strip of dunnage. The dunnage is provided in a crate containing one or more items to be shipped. [0003] Some converting machines produce dunnage products that are primarily used to provide cushioning in packaging to prevent or minimize damage to the contained cargo in transit. For example, US Patent No. 5,674,172, incorporated herein by reference, discloses a cushion conversion machine for converting sheet stock material into a cushioning dunnage product. The buffer conversion machine includes a forming assembly that rotates the lateral edges of the sheet stock material inwardly to form a strip having a three-dimensional shape with a pillow separated from the intermediate strip. The ...
