ABSTRACT:
FIELD OF THE INVENTION
This invention relates to distributors for the deposit of melted solid products in the interior of containers, the containers being placed under the distributor.
BACKGROUND OF THE PRIOR ART
One of the operations carried out industrially is the deposit of products which exit from the production line within containers where they are collected, the containers being of every type or being intended for particular uses. Specifically, when one operates with a continuous cycle, it is necessary to provide an installation which allows to collect individual pieces which continuously exit from the operating machine and to provide for the deposit of the same pieces within containers for the collection, and after the containers are filled up they are removed and substituted with other empty containers.
The present state of the art is that apparatuses and installations for the transport are provided which have rendered the entire operation automatic, but they are constructively very complex, require a great deal of space and are of high cost. In particular, in the field of presswork operation operating with injection or by blowing of the plastic materials, the present state of the art for the best filling up of the containers requires that the containers be capable of moving with respect to the opening of the unloading of the material to be deposited, the opening remaining fixed so that the containers stop one at a time corresponding to the same opening up to the point when they are filled.
This type of deposit has serious drawbacks. The first drawback is due to the fact that it is necessary to construct mechanisms which are frequently complex in order to achieve the motion of the containers.
The second drawback is due to the necessity of constructing a structure which is sufficiently strong in order to carry out the mechanism of motion and the individual containers which may be empty and filled.
A third drawback is due to the fact that the advance of the containers of the type step-by-step which involves each item to be handled each time, all the containers must have the same size so that if the dimension of the container is changed it is necessary to modify the installation which regulates the motion of the containers.
A further drawback is due to the fact that the containers being moved along a movable plane are made with a rigid structure generally of a plastic material, usually called “casse” cases, which subsequently must be emptied in order to fill out the boxes usually made of paperboard in which the products are packed and shipped to clients.
SUMMARY OF THE PRESENT INVENTION
An object of the present invention is to provide an installation according to which the deposit of the melted products from the unloading opening within the containers in which they are collected is carried out constructively simply and which allows to fill out the containers in a regular and uniform manner; the containers having dimensions, volumes and weights which are different without modifying the structure of the apparatus.
A further object of the invention is to use, instead of rigid containers, directly the boxes made of paperboard which are used for packing the products so that after the boxes are filled it is sufficient to close them and they are ready for shipment, a fact which is very advantageous from an economical point of view.
These objects are achieved with an installation in which advantageously both the unloading opening and also the boxes in which the products are to be collected are still and there is used a device capable of collecting continuously the products being unloaded from the same opening to be deposited, always continuously, in the interior of the same boxes, depositing the product in a regular fashion along the entire surface occupied by the boxes made of plastic material, the so-called “casse” cases, which subsequently must be emptied to fill the boxes, generally made of paperboard, with which the products are packed and shipped to clients.
According to the invention an installation is provided in which the deposit of the melted products from the unloading opening within the container in which they are collected is provided in a constructively simple manner and which allows to fill in a regular and uniform manner the containers which have different dimensions, volumes and weights, without modifying the structure of the machine.
A further object of the invention resides in the use of, instead of rigid containers, directly the boxes made of paperboard used for packing the products so that after the boxes are filled, it is sufficient to close them and they are ready for shipment with a great deal of advantage from an economical point of view.
All these objects are achieved with an installation in which advantageously both the unloading opening as well as the boxes in which the products are to be collected are still and a device is provided capable of collecting continuously the products being unloaded from the same opening to be deposited, always continuously, in the interior of the same boxes, distributing the products in a regular fashion along the entire surface occupied by the same boxes, the boxes being placed under the same device, the boxes eventually being positioned above a pallet which facilitates the transportation.
This device which constitutes an essential feature of the present invention, is substantially composed of a carrier which is placed between the unloading opening of the melted products and the boxes in which the products are collected and which are placed under the unloading opening. This carrier is constituted essentially of a carriage capable of being displaced on a horizontal plane according to the two perpendicular directions in such a manner as to engage and to cover with its motion the entire area occupied by the boxes which are placed under the carriage and which are disposed in a manner which can be casual or they may be aligned and/or may be placed side by side one to the other in a predetermined manner.
Another essential feature of the invention is to provide a conveyor belt placed on the movable carriage of the type preferably having a close ring with parallel axes capable of advance motion in two opposite directions so that the products which are placed on the conveyor belt may fall alternatively from one side or the opposite side. In such a manner, as it is easily understandable, when one places the unloading opening of the product in the center of the area under it in which are present the boxes, the course of the carriage is cut in one-half because varying the direction of advance of the conveyor belt, the pieces will fall within the boxes which are disposed respectively on the right and on the left of the same opening.
