Abstract

A method and an apparatus are disclosed for assembling kits of sanitary products which involves loading of the sanitary products into containers including a plurality of independent housings for the sanitary products, each of the housings being configured to allow loading of a sanitary product therein and withdrawal of the sanitary product therefrom independently of the other housings.

First claim

The invention claimed is:

1. A method for assembling kits of sanitary products, comprising:
receiving a sanitary product output from a plurality of manufacturing machines thereof,
transferring the sanitary products in the sanitary product output from each manufacturing machine of the plurality of manufacturing machines into a respective container, each container including a plurality of independent housings for the sanitary products, each of the plurality of housings being configured to allow loading of a sanitary product therein and withdrawal of the sanitary product therefrom independently of the other housings of the plurality of housings, and
collecting sanitary products from the plurality of housings of said containers and assembling a kit of sanitary products comprising a plurality of sanitary products from different containers,
wherein said transferring the sanitary products comprises receiving the sanitary product output from the plurality of manufacturing machines onto a transfer conveyor at a drop off location, and handling the sanitary products to a container loading location whereat the sanitary products are loaded into respective housings of the plurality of housings.

2. The method of claim 1 , wherein the transfer conveyor comprises a plurality of conveyor vanes, each sanitary product being dropped off at a respective conveyor vane of the plurality of conveyor vanes.

3. The method of claim 2 , wherein each container is a rack container comprising a rack of housings, each of said housings being separated by a baffle, wherein each baffle includes a first portion and a second portion arranged on opposite sides of a cutaway, the cutaway extending across the rack of housings, wherein each of the housings has an inlet opening, all of the inlet openings facing on one and the same side of the container, and wherein the cutaway is arranged on an opposite side to the inlet openings.

4. The method of claim 3 , wherein the plurality of conveyor vanes each comprise a first portion and a second portion apart from the first portion.

5. The method of claim 4 , wherein transferring the sanitary products in the sanitary product output from each manufacturing machine into the respective container comprises:
providing a container loading unit at the transfer conveyor on an opposite side of the transfer conveyor than the respective container, the container loading unit comprising a transfer device, the transfer device being comb shaped and including a plurality of teeth protruding from a shaft and defining compartments therebetween,
stopping the transfer conveyor at the container loading unit so that each tooth of the plurality of teeth of the transfer device is aligned with a root of a vane of the plurality of vanes of the transfer conveyor, whereby each compartment between adjacent teeth is also aligned with a corresponding housing of the respective container,
advancing the transfer device into the vanes, thereby bringing the teeth in between the first portion and the second portion thereof, and enclosing the sanitary products into the respective compartments of the transfer device,
further advancing the transfer device into the respective container, thereby bringing the teeth between the first portion and the second portion of the baffles, and sliding the sanitary products into the respective housings,
retracting the transfer device from the respective container.

6. The method of claim 5 , wherein said container loading unit further comprises first and second abutment plates arranged on opposite sides of the transfer device, and also arranged on opposite sides of the plurality of conveyor vanes, the first and second abutment plates being movable to vary a mutual distance therebetween,
wherein the method further comprises:
positioning the first and second abutment plates at a first mutual distance to set up an overlap between each abutment plate and corresponding portions of the sanitary products at the plurality of conveyor vanes prior to advancing the transfer device into the plurality of conveyor vanes,
advancing the transfer device into the plurality of conveyor vanes until a double contact is reached between the shaft and a first end of the products and the first and second abutment plates and a second end of the sanitary products,
positioning the first and second abutment plates at a second mutual distance, higher than the first mutual distance, to cancel the overlap between each abutment plate and corresponding portions of the sanitary products at the plurality of conveyor vanes prior to advancing the transfer device into the plurality of conveyor vanes,
further advancing the transfer device into the respective container.

7. The method of claim 6 , wherein said first distance is a minimum mutual distance, and said second distance is a maximum mutual distance.

8. The method of claim 1 , wherein loading of the sanitary product into the respective housing comprises positioning the sanitary product at the respective housing, and sliding the sanitary product into the respective housing.

9. The method of claim 1 , wherein said collecting sanitary products from the plurality of housings of said containers and assembling the kit of sanitary products comprises gathering the containers at a kit assembling area and withdrawing the sanitary products from the plurality of housings of the containers at the kit assembling area to assemble the kit of sanitary products.

10. The method of claim 9 , wherein said withdrawing the sanitary products from the plurality of housings comprises picking the sanitary products by means of a robot, and further assembling the kit of sanitary products by the robot.

11. An apparatus for assembling kits of sanitary products, the apparatus comprising:
one or more transfer conveyors configured to receive a sanitary product output from a corresponding sanitary product manufacturing machine,
a plurality of containers, each container configured to be loaded with sanitary products from one or more sanitary product outputs, and each container including a plurality of independent housings for the sanitary products, each of the plurality of housings being configured to allow loading of a sanitary product therein and withdrawal of the sanitary product therefrom independently of the other housings of the plurality of housings,
a container loading unit configured to retrieve sanitary products from a transfer conveyor and load the sanitary products into corresponding housings of the plurality of housings of a respective container of the plurality of containers, the container loading unit being arranged at a container loading location at least in part on an opposite side of the transfer conveyor than the respective container at the container loading location,
a container handling facility configured for gathering the plurality of containers at a kit assembly location,
a withdrawal unit configured for collecting a sanitary products from the plurality of containers at the kit assembly location and assembling the collected sanitary products into a kit of sanitary products.

12. The apparatus of claim 11 , wherein:
each container is a rack container comprising a rack of housings, each of said housings being separated by a baffle, wherein each of the housings has an inlet opening, all of the inlet openings facing on one and the same side of the container, and further wherein each baffle includes a first portion and a second portion arranged on opposite sides of a cutaway, the cutaway extending across the rack of housings and being arranged on an opposite side to the inlet openings,
the transfer conveyor comprises a plurality of the conveyor vanes, each configured to
