Abstract
An apparatus for packing a food product in a container to be used in infusion machines, preferably to obtain a beverage such as coffee, includes a frame for supporting means for feeding an external body of the container and means for making and inserting a bag configured with fluted sidewalls in the external body. The means for making and inserting the bag has at least one operating unit with a bag making component, an insertion component, and a conveyance for transporting the bag between the making component and the insertion component.
Claims20
An apparatus for packing an infusion or extraction product in a container, the container comprising an external body and a bag made of porous and/or filter material and configured with fluted sidewalls, the apparatus comprising:
- a supporting frame,
- a feeding member configured to support and move a plurality of external container bodies in a feed direction, and
- a first and a second making and inserting unit, each comprising:
- a respective making device configured to cut circular-shaped portions from a single strip of material and to make a plurality of bags from respective ones of the circular-shaped portions;
- a respective inserting device for inserting the bags inside respective ones of the external bodies;
- and
- a respective conveying device for conveying the bags from the respective making device to the respective inserting device, the making devices of the first and the second making and inserting unit being located upstream and downstream, respectively, of the corresponding respective inserting device along the feed direction;
- wherein the first and second making and inserting units operate on respective first and second external bodies, with the first external bodies being offset, as supported by the feeding member, relative to the second external bodies in a direction transverse or perpendicular to the feed direction, and
- wherein the making device of each of the first and the second making and inserting units comprises a pushing element for pushing first faces of the cut portions into a respective forming hopper and further comprises an accompanying element for accompanying the cut portions through the forming hopper, the accompanying element engaging second faces of the cut portions, opposite the first faces engaged by the pushing element.
A method for packing an infusion or extraction product in a container comprising an external body and a bag made of suitable porous and/or filter material and configured with fluted sidewalls, comprising the steps of:
- feeding by a feeding member a plurality of external bodies of containers in a plurality of parallel rows inside respective housing and supporting cavities of the feeding member along a feed direction;
- feeding a strip of porous and/or filter material;
- obtaining, by cutting, from the strip of porous and/or filter material a plurality of portions each designed to make a bag with fluted sidewalls;
- folding the portions to form corresponding bags with fluted sidewalls at a device for making the bag;
- inserting the bags in corresponding seats of a conveying device;
- moving the seats to position the seats and the bags above respective ones of the external bodies at locations upstream or downstream of the device for making bags with respect to the feed direction;
- inserting the bags inside corresponding external bodies housed inside the respective housing and supporting cavities of the feeding member;
- wherein the step of folding the portions to form corresponding bags with fluted sidewalls comprises clamping the portions between pushing elements, which engage upper faces of the portions, and accompanying elements, which engage lower faces of the portions, to form clamped portions and forcing the clamped portions inside a forming hopper, and
- in which first bags are inserted inside corresponding first external bodies and second bags are inserted inside second external bodies, the first external bodies being offset along the feed direction relative to the second external bodies.
An apparatus for assembling external bodies and filter bags into multiple containers and packing the assembled containers with an infusion or extraction product, the containers each comprising an external body and a filter bag, the apparatus comprising:
- a feeding member for feeding the external bodies in a feed direction;
- a first and a second making device each configured to cut circular-shaped portions from a single strip of filter material to make a respective subset of the filter bags;
- a first and a second inserting device each configured to insert the filter bags of a respective said subset inside respective ones of the external bodies, wherein the first making device is downstream of the first inserting device along the feed direction and the second making device is upstream of the second inserting device along the feed direction,
- wherein the first inserting device is configured to insert the filter bags of the respective subset inside respective ones of the external bodies only upstream of the second inserting device along the feed direction and the second inserting device is configured to insert the filter bags of the respective subset inside the respective ones of the external bodies only downstream of the first inserting device along the feed direction, and
- wherein the first inserting device and the second inserting device are offset from each other in a direction transverse or perpendicular to the feed direction, so that the first inserting device and the second inserting device insert respective filter bags in different external bodies of a common row of external bodies disposed perpendicular to the feed direction.
