Abstract
A conveyor belt 1 has pivotable flights 2,2 and means 4 which extend below the belt 1, in order to engage with an activating rail 5, which flips each flight 2 into an active or upright position as each means 4 comes into contact with the activating rail 5. Also disclosed is a corresponding broader conveyor arrangement, further featuring driving rollers and other common conveyor features. The arrangements may help at the input and output end of the conveyor, in properly catching items dropped onto the input end of the conveyor, and stopping items from sticking to the conveyor at the output end. The conveyor may be used for transporting foodstuffs.
Description
Conveyor and conveyor structure
Field of the Invention
The preseni invention relates to a conveyor belt and a conveyor siruclure including a conveyor belt according to the invention. The conveyor belt is particular in that it in-corporates parts which are able to be activated such that at least a part of the conveyor belts surface may be angled relative to the conveyor belt surface such that a flight, also known as a product support, is created. These flights arc typically used on inclined or declined conveyor structures in order to be able to transport a product up or down.
Background of the Invention
A problem with these flights is the fact that the product may stick to the surface of the flight such that as the conveyor belt on the return trip has the flights pointing down-wards, any products which were stuck onto the flight may drop ofE for example on the floor below the conveyor. The product, particularly in the food handling industry thereby becomes contaminated and must bc destroyed. A further disadvantage in this connection is the mess created by debris/products under the conveyors, creating clean-ing issues and loss of potentially valuable product. This loss of product is particularly true in the food industry where the amount of product, for example when poultry, shrimp, shellfish or fish is transported on these types of inclined eonveyors may be up to 15-20% which is a substantial economic loss.
A further problem with the prior art flights is the fact that where product is transferred from a regular conveyor onto a conveyor including flights there is an interface zone, i.e. a distance between the conventional conveyor and the conveyor including the flights such that the flights may pass this first conveyor. As a flight passes the plane of the first conveyor an opening arises such that product may fall between the two con-veyors down onto the floor or the following flight. In order to counter this various "bridge" constructions have been implemented to bridge the gap.
A similar situation is present at the top of the conveyor, where the conveyed product is delivered to the next process step, for example another conveyor. It is here necessary to arrange the conveyor below the inclined conveyor at a distance allowing the flights to pass the following conveyor. For some products the drop from the inclining convey-or to the following conveyor may damage the product or create turbulence which is not desirable in a transport line, and therefore the conveyor may work at reduced speed or be unsuitable for these types of products altogether.
Object of the Invention Consequently it is an object of the present invention to provide a conveyor belt and a conveyor which addresses these problems and provides additional advantages.
Description of the Invention
The invention addresses this by providing a conveyor belt of the type having a width, and a length, where the width and length defines a plane, and a thickness orthogonal to said plane between the transport surface of the conveyor belt and the underside, said belt providing a substantially endless transport surface, and that at spaced intervals along the length of the conveyor belt pivotable product supports are provided, said product supports having a product support surface where said product supports by means extending below the thickness of the conveyor belt may be pivotcd from a posi-tion where said product support surface is substantially flush with the upper surface of the conveyor belt and into a position where the product support surface is at an angle with the conveyor belt surface.
By being able to activate and thereby determine when the product supports or flights shall be raised it is possible to incorporate the conveyor belt into a conveyor structure without the problems as mcntioncd above with respect to the intcrfaccd two neigh-bouring adjacent conveyors. If the flights are not raised when the conveyor belt turns around the sprocket wheels it is possible to utilize traditional means of transferring a product from one conveyor belt to the conveyor belt incorporating the inventive raisa-ble flights. In a similar manner, before delivering the product for further processing at the end of the conveyor the flights maybe lowered such that the adjacent conveyor belt may be positioned immediately adjacent the conveyor.
For a number of products it is desirable to provide a scraper at the end of the conveyor in order to clean any product or debris off the conveyor belt. Having flights arranged permanently substantially orthogonal to the surface of the conveyor belt, makes the use of a scraper very difficult and complicated.
In order to raise and lower the flights activating rails are arranged on the conveyor structure in those zones where it is desirable to raise the flights. The activating rails engage the means projecting below the conveyor belt such that by engagement with the rails the product support surface is %rced upwards. Depending on the size of the means projecting below the conveyor belt the ifight may be raised more or less, how-ever, typically the means are designed such that the product support surface will be raised to an angle corresponding to approx. 90 degrees with respect to the transporting surface of the entire conveyor belt In a further advantageous embodiment of the invention apertures are provided in the conveyor belts surface coinciding to where the means extends below the thickness of the conveyor bell in order to allow said product support surfaces to pivot by activating said means, from a position where said product support surface is substantially flush with the upper surface of the conveyor belt and into a position where the product sup-port surface is at an angle with the conveyor belt surface.
In this manner the activating means, i.e. the means projecting below the surface of the conveyor belt in corporation with activating rails in the conveyor sub structure can easily be integrated into conveyor belts, without interfering with and constructions along the longitudinal sides of the conveyor belt or sub-structure.
As an alternative embodiment to the embodiment mentioned above the means extend-ing below the conveyor belts thickness arc arranged adjacent longitudinal sides of the conveyor belt In a still further preferred embodiment the product supports are provided with hinge blocks, said hinge blot are fastened and/or integral with the conveyor belt and where an axle comiects the product support surface through the hinge block with the means extending below the thickness of the conveyor belt.
Thereby is provided a simple, reliable and cleaning friendly construction. It is further- more simple to maintain and inspect. In embodiments where the hinge blocks are ap-plied and fastened to the conveyor belt, these may be retrofitted to existing conveyor belts, or may be replaced as needed without disturbing the entire conveyor belt. In this maimer the down time when repairs are necessary is minimized.
Furthermore the hinge blocks may also provide reinforcement to the conveyor belt as such.
The hinge blocks may be fastened in any appropriate manner such as by bolts, adhe-sives, vulcanised onto the surface of the conveyor belt etc. The invention is also directed at a conveyor structure comprising a substructure defin-ing the path of an endless conveyor belt, where belt drive means are arranged at either end of said path, where at least the drive means in one end of the conveyor structure is provided with propulsion means for propelling said conveyor belt along the path, thereby defming a forward upper run and a return lower run, and where the conveyor belt has a width, and a length, where the width and length defines a plane, and a thick-ness orthogonal to said plane, said belt thereby provides a substantially endless transport surface, and that at spaced intervals along the length of the conveyor belt pivotable product supports are provided, said product supports having a product sup-port surface where said product supports by means extending below the thickness of the conveyor belt may be pivoted from a position where said product support surface is substantially flush with the upper surface of the conveyor belt and into a position where the product support surface is at an angle with the conveyor belt surface; where said conveyor structure further comprises one or more activating rails, arranged under the conveyor belts path, in positions where it is desirable to engage the means projecting below said conveyor belt, thereby pivoting the surface of the product supports out of the conveyor belts surface plane.
The conveying path is in a further embodiment is defmed by a first substantially hori-zontal section, connected to an inclined or declined section, which in turn is connected to a second substantially horizontal section, where said second horizontal section is elevated or lowered relative to said first substantially horizontal section.
In such an embodiment the product supports comes into action, particularly by round or roundish objects, or on conveyor belts having very little friction between the prod-ucts conveyed and the surface of the conveyor. In these situations the product supports helps to elevate the products on inclined parts or hinders products in tumbling down the conveyor in downhill sections.
Additional advantages will be obtained by the further embodiments as set out in further dependent claims, and as explained below.
Description of the Drawing
The invention will now be explained with reference to the accompanying drawings wherein Figure 1 a cross section through a conveyor belt according to the invention; Figure 2 illustrates a perspective view of the section of conveyor belt illustrat-ed in figure 1; Figure 3 illustrates a side view of an alternative embodiment of a conveyor belt according to the invention.
Detailed Description of the Invention
In figure 1 is illustrated a cross-section through part of a conveyor including a convey-or belt 1 according to the present invcntion. The conveyor belt has a transport surface and an underside 11. The conveyor belt I will in a traditional fashion be arranged around drive pulleys in either end of the conveyor belt's path, and the conveyor belt will be a substantially endless belt, such that a substantially endless conveying surface is provided between the two drive pulleys (not illustrated). At spaced intervals along the length of the conveyor belt pivotal product supports 2, 2' are provided. The prod-uct supports 2, 2' have a product support surface 3 which is designed to engage and support any products/objects suitable to be transported by the conveyor 1. The product supports 2, 2' are pivotally arranged in the conveyor belts 1 such that they, when not activated are in a position as illustrated in the left hand side of figure 1 whereas when they are activated the product support surface 3 will be inclined relative to the top sur-face 10 of the conveyor belt as illustrated in the right hand side of figure 1.
In the non-activated state as illustrated with product support 2 the product support is substantially flush with the transport surface 10 of the conveyor belt 1 whereas when the product support 2' is activated the product support surface 3 will be arranged at an angle to the transport surface 10. The angle is determined by the means 4 and the means' 4 engagement with an activating rail S arranged under the underside 11 of the conveyor belt 1. The means 4 will engage the activating rail 5 as the conveyor travels in the direction indicated by the arrow 6 whereby the means 4 will engage the rail 5 and thereby be urged upwards into a position as indicated in the right hand side of figure 1.
Consequently the product supports can be activated and deactivated as desired, simply by arranging engagement rails under the conveyor belt in desired positions and for de-sired distances.
It is also foreseen that the lateral distance between the means for different product sup-ports 2 may vary, such that a first plurality -for example every other or third has a first lateral distance between the means 4, whereas the lateral distance between the means 4 of other product supports is different. With this configuration it is possible to vary the distance in the conveyor belts travelling direction, between adjacent activated product supports, simply by arranging engagement rails corresponding to the lateral distances of the mean/product supports which it is desirable to activate.
Turning to figure 2 a perspective view of an embodiment of the invention correspond- ing to the embodiment described with reference to figure 1 is illustrated. In this illustra-tion the activating rail 5 is not visible, but apertures 7 provided in the conveyor belt 1 are indicated. These apertures serve to allow the means 4 to extend below the under-side 11 of the conveyor belt. Furthermore, it is illustrated that the product supports 2, 2' are provided with hinge blocks 8, in this embodiment moulded into the transport surface 10 of the conveyor belt. An axle 9 integral with the product supports 2, 2' is arranged in the hinge block 8 to allow the product supports 2,2' to pivot freely.
The means 4 serve a flirther purpose in that as the conveyor belt I travels on and the activating nil ends, gravity will urge the product support due to the weight of the means 4 to Ibid back into the position as indicated in the left hand side of figure 1 and figure 2.
Turning to figure 3 a further embodiment of the invention is illustrated where an end-less conveyor belt 1' is provided with products supports 2". The product supports are arranged on top of the transport surface 10, in that hinge blocks 8' are arranged along opposite longitudinal sides of the conveyor belt 1. Integral with the product supports 2" are activating means and axles 13 which as explained above with reference to the means 4 may be activated when engaging a nil underneath the conveyor belt 1. This embodiment may either be "borne" with the hinge blocks and the product supports 2' or they may be installed as a reconfiguration of a standard flat conveyor belt by adher- ing or bolting the hinge blocks 8' onto the surface 10 of the conveyor belt 1'. The em- bodiment illustrated in figure 3 fhnctions in the same manner as the embodiment de-scribed with reference to figures 1 and 2.
Above two different embodiments of the invention have been explained with reference to the figures, but the scope of protection shall onlybe limited to the extent afforded by the appended claims.
