The present invention relates to a distributor apparatus for products, in particular for food products cut into slices.
When cutting and portioning food products, high-performance slicers are used today with which the food products are cut into thin slices. The slices are subsequently layered in stacks or in overlapping portions, are weighed and are packed in a packaging machine. It is desirable in this process to distribute the products of an incoming product flow such that the outgoing product flow has a different grouping. For example, the incoming product flow can include individual products arranged in the conveying direction one after the other, whereas the outgoing product flow has groups in which two, three, four or more products are arranged next to one another.
It is the object of the present invention to provide a distributor apparatus for products which has a high flexibility with respect to the distribution variants.
This object is satisfied by the features of claim 1 and in particular by a distributor apparatus for products having an infeed belt and an outfeed belt which are arranged in the conveying direction one after the other. At least one distributor belt is furthermore provided which is arranged in the conveying direction between the infeed belt and the outfeed belt. In accordance with the invention, the distributor belt is driven in and counter to the conveying direction and is displaceable transversely to the conveying direction. The distributor belt is divided at least into two in the conveying direction, with each part of the distributor belt having a drive. The drives are independent of one another, i.e. they can be driven independently of one another in or counter to the conveying direction.
An incoming product flow can be divided in an extremely flexible manner into an outgoing product flow of a different grouping by the distributor apparatus in accordance with the invention. It is in particular possible by using at least one divided distributor belt with independent drives to distribute an incoming product flow such that the members of a grouping are distributed from an even number to an odd number (or vice versa).
Any desired products can be used within the framework of this invention. The invention is, however, particularly suitable for the distribution of cut food products which can be supplied either individually or as overlapping or stacked portions.
Advantageous embodiments of the invention are described in the description, in the claims and in the drawing.
In accordance with a first advantageous embodiment, at least one distributor belt has substantially the same width as the outfeed belt and is in particular wider than the infeed belt. It is hereby possible to achieve a broadening of the incoming product flow by the distributor apparatus.
In accordance with a further advantageous embodiment, the infeed belt is arranged above at least one distributor belt and is in particular downwardly inclined at least regionally. The incoming product flow can hereby be transferred gently from the infeed belt to the distributor belt.
The infeed belt preferably overlaps a distributor belt at least partly, whereby it is achieved that products can be conveyed from the distributor belt behind the front end of the infeed belt such that a following product supplied by the infeed belt can be placed next to the product already placed on the distributor belt.
In accordance with a further advantageous embodiment of the invention, the infeed belt and at least one distributor belt are vertically spaced apart above one another such that products located on the distributor belt can be conveyed beneath the infeed belt. With this embodiment, it is possible, on a reverse movement of the distributor belt, to guide products already located on the distributor belt beneath the infeed belt, whereby higher distributor speeds are achieved, without the products located on the distributor belt being impaired.
In a further embodiment of the invention, two distributor belts are arranged in the conveying direction one after the other between the infeed belt and the outfeed belt. The distributor belts in this process are displaceable independently of one another transversely to the conveying direction and the parts of the distributor belts are driven independently of one another in and counter to the conveying direction. In this manner, practically all redistributions can be realized, in particular the distribution of the groupings of a product flow from an odd number to an even number.
In this embodiment, the distributor belts can moreover be displaceable simultaneously in the same direction or in the opposite direction transversely to the conveying direction. This permits an extremely fast and versatile distribution of the product flow, because regroupings can be carried out simultaneously on both distributor belts.
The present invention will be described in the following purely by way of example with reference to advantageous embodiments and to the enclosed drawings. There are shown:
a-4i a schematic procedure of a ¼ distribution with the first embodiment;
a-5h a schematic procedure of a ⅔ distribution with the first embodiment;
As
The distributor belt V, i.e. the two conveyor belts 14A and 14B arranged next to one another, are additionally displaceable transversely to the conveying direction with the help of a displacement device, as is indicated by a double arrow in
As in particular
In
a shows a state in which the first supplied product has already been transferred from the conveyor belt 12 of the infeed conveyor Z to the conveyor belt 14B of the distributor belt V. Before the product with the number 2 is transferred onto the distributor belt V, it is transversely displaced by a product width. At the same time, the conveyor belt 14B is displaced counter to the conveying direction such that, when the product with the number 2 is transferred, both conveyor belts 14A and 14B can be moved synchronously in the conveying direction such that both products 1 and 2 come to lie aligned next to one another.
Subsequently, a further transverse movement and a further reverse movement is carried out by the distributor belt V such that the product with the number 3 can be transferred to the distributor belt V in the manner described above (cf.
As
The distributor belt V is subsequently moved back into its left hand end position (cf.
As is shown in
Subsequently, the distributor belt V is moved back by a product width transversely to the conveying direction (
In the following step, the distributor belt is guided back into its left hand end position such that the next group of three can be transferred from the distributor belt V to the conveyor belt 16 of the outfeed belt A. At the same time, the next following group of two with the number 4 is transferred from the infeed belt to the distributor belt such that the distribution cycle can start again.
As becomes clear from the above, it is important in this distribution that the distributor belt has two part belts drivable independently of one another.
As
As in particular
In
In the second embodiment, two distributor belts V1 and v2 are arranged in the conveying direction one after the other between the infeed belt Z and the outfeed belt A. The distributor belts V1 and V2 adjoin one another directly in an aligned manner. They are driven independently of one another in the conveying direction.
The distributor belts V1 and V2 are furthermore displaceable independently of one another transversely to the conveying direction by linear drives not shown in
The distributor belts V1 and V2 both have approximately the same width as the outfeed belt A. The width of the infeed belt Z amounts to approximately three quarters of the width of the outfeed belt A. The distributor belt V1 directly adjoins the infeed belt Z in one plane, whereas the distributor belt V2 directly adjoins the outfeed belt A in the same plane.
The distributor belts V1 and V2, like the distributor belt V of the first embodiment, are divided into two and each consist of two conveyor belts 15A, 15B and 16A, 16B respectively arranged in parallel and coaxially with independent drives. All four conveyor belts can be moved in and counter to the conveying direction independently of one another.
The conveyor belts 15A and 16A are approximately equally large and arranged in the conveying direction one after the other. Moreover, the approximately equally large conveyor belts 15B and 16B are arranged in the conveying direction one after the other. The width of the conveyor belts 15A and 16A amounts to approximately three quarters and the width of the conveyor belts 15B and 16B amounts to approximately a quarter of the width of the respective distributor belts V1 and V2.
a-7n represent a so-called ¾ distribution. The products are marked with the numbers 1 to 6 and are supplied in groups of three on the infeed belt Z.
a shows a state in which a group of three products with the number combination 1-1-1 supplied from infeed belt Z has already been placed on the distributor belt V1. Then, as shown in
Subsequently, as indicated in
The distributor belt V1 is then displaced by a transverse movement into its right hand end position (
In the next step, which is shown in
Then the infeed belt Z and the conveyor belt 15A are set into motion in the transport direction, whereby the group of three with the number combination 3-3-3 present on the conveyor belt 15A is placed on the conveyor belt 16A. At the same time, a group of three with the number combination 4-4-4 is transferred from the infeed belt Z onto the conveyor belt 15A. In this state (
Now transverse movements are carried out simultaneously by the distributor belts V1 and V2 in order to displace them by a product width in to their left hand end positions (
The distributor belt V2 and the outfeed belt A are then moved on in the conveying direction to transport the group of four 2-3-3-3 on the outfeed belt A onward by a product length and to transfer the group of four 2-4-4-4 from the distributor belt V2 onto the outfeed belt A (
A product group can be distributed from an odd number into an even number using the second embodiment of the distributor apparatus in accordance with the invention. Moreover, a faster and thus more efficient distribution of the products is made possible by the use of two distributor belts on which regroupings take place simultaneously.
To summarize, it can be said that practically all conceivable redistributions of product groupings can be realized using the distributor apparatus in accordance with the invention. This can occur, as described in the first and second embodiments, by the use of one or two distributor belts. Alternatively, a high flexibility of the distributor apparatus can be achieved by arranging a plurality of distributor belts one after the other and by the redistributing use of one or more distributor belts in dependence on the respectively needed distribution variant.
Moreover, the distributor belts can not only be divided in a ratio of 1:3, i.e. asymmetrically, but it is rather the case that other asymmetrical or symmetrical divisions of the distributor belts are also conceivable to realize a versatile use of the distributor apparatus.
