Abstract

In machinery for sorting and batching, receiver bins with an openable bottom are used, and in connection with foodstuff articles such as pieces or slices of meat, these bins should be made with walls that are profiled for reducing the adherence of the articles. This makes the bins rather expensive, but with the invention a both inexpensive and suitable bin is provided, made as an open carrier framework for holding plate pieces of profiled, heavy plastic sheet material which are clipped onto the framework and may be shaped by simple vacuum forming.

Description

A bowl-shaped bin of turnable or openable type, preferably for reception of foodstuff articles.
The present invention concerns a container element for machines such as sorting and batching machines, in which a number of such container elements are used for the temporary storage of articles, and from which they shall be emptied later. The element can be a weighing bin or a bin for successive receipt of articles for the building up of article portions for collective emptying from the individual containers .
The invention is especially relevant for the foodstuffs industry, where it is current practice to effect a weighing of the individual items or item portions, or to collect already weighed items in a successive manner to form portions for collective delivery of these from the respective containers or bins.
This delivery can be effected by turning the individual containers upside-down or by opening the bottoms of the containers, which in practice demands good stability for the containers, which should thus be configured in sheet metal or possibly as moulded units of suitably heavy plastic material.
It is particularly in the handling of foodstuff items such as pieces or slices of meat that problems can arise with regard to the adherence of these items to the walls of the containers or bins, and it is already known that these wall surfaces can be configured in such a manner that such adherence is minimized, e.g. by giving the sur- faces a corrugated profile or providing the surfaces with scattered projections.
However, where different products are concerned, situations can arise where an optimal configuration of the relevant surfaces is not completely identical, whereby in a given machine it can be desirable to effect a replacement of all the containers when making a changeover for the handling of products of a different kind. This, of course, will be quite costly, not only from the labour point of view but also because the different containers are expensive to produce, regardless of whether their wall parts are configured as embossed metal surfaces or as injection-moulded plastic surfaces with the desired, non-smooth profile. With the present invention it is realised that the containers or bins should be configured as rigid units, but that this can be brought about by the use of an outer supporting framework, e.g. of metal parts, which are suitable for the supportive and replaceable receipt of a wall-forming lining with a desired slide-promoting surface structure, whereby in the relevant situations it is not the bins as a whole which have to be replaced, but only the relevant wall parts. These can well consist of a less rigid material, preferably merely of a semi-stiff plastic foil which can be provided with the desired surface structure by simple and inexpensive vacuum forming, and which in addition is configured with suitable engagement parts for releasable coupling together with the rigid, supporting framework structure. The latter will be considerably cheaper to produce than a container or bin with uninterrupted side surfaces, and the wall parts introduced herein will be even cheaper, because the desired surface configurations can be extremely cheap to produce. A changeover between different productions can thus be effected both easily and quickly in an inexpensive manner and, moreover, the basic configuration of the containers themselves is made cheaper. This is of considerable financial significance, the reason being that the relevant machines are often equipped with a large number of the aforementioned containers.
The use of the above-mentioned supporting framework provides the advantage over support plates that also the outside of the bin is easy to clean effectively, without inaccessible spaces.
The invention will now be explained in more detail with reference to the drawing, in which
Fig. 1 is a perspective view of a bin according to the invention,
Fig. 2 is a corresponding view of the lining part for same,
Fig. 3 is sectional view of the bin in its open state, and Fig. 4 is an end view of a modified bin.
Each end of the bin shown in fig. 1 comprises two trapezoidal end plates 2 arranged opposite each other, and which are held together by being pivotably secured to a surrounding frame 6 at the points 4. Moreover, these end plates are mutually connected by means of a knee- joint 8 with a centre-pin 10 which, when in its lowered position, holds the knee-joint extended almost straight, whereby the end plate positions will determine a bin with closed bottom, while a lifting. of the pin 10 will cause the joint 8 to break upwards and cause the end plates to swing for the opening of the bottom of the bin, cf . fig. 3.
This embodiment of the bin is described in WO 95/01909, where the end pieces at the opposite ends of the bin are mutually connected by means of outer side pieces and bottom-plate pieces for integrated bin formation .
According to the present invention, however, the same end plates are mutually connected only by the longitudi- nal rods 12,14,16, i.e. without fixed side pieces and bottom walls .
The necessary side parts are formed by separately- produced plate elements 18 which, as shown in more detail in fig. 2, are configured with edge openings 20 which can be brought into holding engagement with all or some of the connection rods 12-
16 with snap-lock effect. These edge openings are provided in the outer edges of open girder profiles 19 extending lengthwise with the end edges of the plate elements 18 for the stiffening of same in the upwards direction .
The wall plate elements 18 can expediently be made merely of semi-stiff plastic, whereby in a simple manner, i.e. by vacuum forming of a plastic foil, they can be provided with a serrated surface profile which will counteract adherence of the items which are delivered to the individual bins. This appears clearly from the drawing. The optimal configurations of the bin walls can vary for different products, but it will be understood that precisely with the invention it is possible to effect such an adaptation of the bin in a simple and inexpensive manner, in that the wall elements 18 can simply be changed with wall elements of other configurations which are also inexpensive to produce, in that they are not required to serve as constructive stabilizing elements between the opposing end plates, regardless of the material from which they are made.
In fig. 4 is shown an embodiment which is based on the precondition that in certain plants it will be acceptable that the upper, upright side walls 18' of the bin can be fixed plate parts, no matter whether they are smooth or profiled to reduce adherence, but otherwise without requiring product -adapted linings, i.e. when the tendency for the relevant products to adhere to these steep surfaces will generally be low. As shown, it can be sufficient for the lower, inclined bottom wall parts, here indicated by the reference number 22, to constitute replacement parts cf. fig. 1-3. Moreover, for the opening of the bin bottom, it can also be sufficient to arrange a swinging-down of just these bottom parts, while the upper side walls 18' remain upright. This is also shown in fig. 4, where the bottom wall parts 22 are shown in both the closed and the open position.
The invention is not limited to any certain type of profiling or configuration of the slide surfaces. For example, alternative use can be made of a nubbly or vertically-profiled surface, and in extreme cases the surfaces can be completely plane and smooth.
