Background and Prior Art
Fragile goods like foodstuffs such as fruit and vegetables need careful transporting during harvesting and processing and specialist conveyor belts known as pintle belts are commonly used to convey the goods. Pintle belts are conveyor belts with a series of“fingers” known as pins that gently carry, support and or retain the goods during the running of the conveyor belt. Existing pintle belts are relatively difficult and costly to manufacture as the belt requires the moulding of a sheet complete with the fingers. The finger sheet is subsequently glued onto a backing layer to provide belt strength and durability. The use of adhesives is undesirable given their environmental concern and the belts currently in existence are difficult to repair or recycle. The current disclosure aims to overcome at least some of these disadvantages.

Description of Preferred Fmbodiments
Shown in Fig. 1 is an exemplary application of an embodiment of conveyor belt system 10 in accordance with the current disclosure, wherein a conveyor belt 15 is used to transport fragile items such as foodstuffs 17 like fruit and vegetables.
Further referring to Figs. 2-7, the conveyor belt 15 comprises at least one belt element 20 having a conveying side 22 configured to transport objects or materials and a driving side 24 configured to engage with pulleys, rollers and other elements that move and support the conveyor belt 15.
In an embodiment of belt element 20 as shown in Fig 3, conveyor belt 15 is a continuous sheet belt comprising a belt element 20a. Belt element 20a may be formed from a single material or it may have a laminar construction comprising different materials or material configurations (e.g. solid, woven, etc.). The material or materials achieve a desirable combination of flexibility, rigidity, resilience and durability. The belt element 20a needs to be sufficiently flexible to enable it to flex around belt drive/support pulleys/elements (not shown) and potentially cope with non-linear drive paths of the conveyor belt 15. The material choice may also depend on regulations such as those that apply to the food industry. In an embodiment the belt element 20a includes a plurality of solid and woven layers. Due to its sheet character, belt element 20a will comprise only a low number, or even no, joints. Long conveyor belts 15 may of course be formed of multiple belt elements 20a to ease manufacture, assembly, repair or overhaul.
In another embodiment, as shown in Fig. 4, the conveyor belt 15 is formed from a series of connected modular belt elements 20b to form a continuous chain-link belt. The belt elements 20b may be constructed from one or more materials and may be formed via a moulding or casting process. The modular belt element 20b can inherently be stiffer than a sheet belt element 20a as the ability to flex around belt drive/support pulleys/elements (not shown) and potentially cope with non-linear drive paths comes from the chain-link construction including many relatively short belt elements 20b combined with a relatively large number of hinges in between the belt elements 20b.
The driving side 24 may be provided with a surface 25 which is smooth or has surface structures 26 such as an undulating pattern 26a or ribs 26b. The surface structure 26 may aid in the engagement of the belt element 20 with any drive puheys/elements to achieve a smooth conveying motion.
The belt element 20 is provided with at least one aperture 30. The aperture 30 may be formed by any suitable method such as for example hole-punching and/or cutting the sheet belt element 20a or forming the aperture in the modular belt element 20b during the moulding or casting process.
In an embodiment the belt element 20 is provided with a plurality of apertures 30 that may ah have substantially the same cross-sectional diameter. In an embodiment the belt element 20 is provided with a plurality of apertures 30 that may have varying cross-sectional diameters. In an embodiment the belt element 20 is provided with a plurality of apertures 30 that are distributed substantially evenly. In an embodiment the belt element 20 is provided with a plurality of apertures 30 distributed in varying patterns.
The conveyor belt system 10 further comprises at least one pin 40 as shown in detail in Fig. 8. The pin 40 has a conveyor portion 50 configured to project from the conveying side 22 of the belt element 20 and to engage the objects or material to be transported. The pin 40 has an extension portion 60 configured to at least partially extend through its corresponding aperture 30. The pin 40 further has a retainer portion 70 configured to retain the pin 40 in the belt element 20.
As can be seen from Figs 1-4, the pin 40 extends substantially at a right angle to the conveying side 22 of the belt element 20. It may alternatively be said that the pin 40 extends at an angle of about 90° to the conveying side 22 of the belt element 20.
In some embodiments, the conveyor portion 50 of the pin projects substantially at a right angle from the conveying side 22 of the belt element 20. It can alternatively be said that in some embodiments, the conveyor portion 50 of the pin projects at an angle of about 90° from the conveying side 22 of the belt element 20.
In an embodiment the pin 40 is fitted to the belt element 20 by inserting the conveyor portion 50 into the aperture 30 and pushing/pulling the pin through the aperture 30 until the extension portion 60 is positioned in the aperture 30. The conveyor portion 50 may have a tapered transition section 52 to aid the fitting process. The conveyor portion 50 may have a bottom end 55 configured to butt up against the belt element 20. The bottom end 55 has a cross- sectional diameter larger than the cross-sectional diameter of the corresponding aperture 30. The conveyor portion 50 may have a tip end 56 with a reduced diameter relative to other sections of the conveyor portion 50 enabling the tip end to be more flexible than the rest of the conveyor portion 50 so as to enable a softer engagement with the material or objects it is intended to engage.
The extension portion 60 has a diameter adapted to its corresponding aperture 30. In an embodiment, the extension portion 60 has a cross-sectional diameter smaller than the cross- sectional diameter of its corresponding aperture to allow a degree of movement. In an embodiment, the extension portion 60 has a cross-sectional diameter substantially similar to the cross-sectional diameter of its corresponding aperture. In an embodiment, the extension portion 60 has a cross-sectional diameter larger than the cross-sectional diameter of its corresponding aperture to provide an interference fit.
The extension portion 60 may extend partially or through the full thickness of the belt element
20.
The retainer portion 70 may have a first end 75 configured to butt up against the belt element 20. The first end 75 has a cross-sectional diameter larger than the cross-sectional diameter of the corresponding aperture 30. In an embodiment the retainer portion 70 has a substantially identical cross-sectional diameter across its full length.
In an embodiment the pin 40 may comprise:
a conveyor portion 50 having a bottom end 55 with a first cross-sectional diameter; an extension portion 60 having a second cross-sectional diameter smaller than the first cross-sectional diameter;
a retainer portion 70 having a first end 75 with a third cross-sectional diameter larger than the second cross-sectional diameter. In an embodiment the conveyor portion 50 may have a body section 57 extending from the bottom end 55, the body section 57 having a cross-section diameter smaller than the first cross-sectional diameter of the bottom end 55. In an embodiment the conveyor portion 50 may further have a tapered transition portion 52 between the bottom end 55 and the body section 57. In an embodiment the conveyor portion 50 may further have a tip end 56, the tip end 56 having a cross-sectional diameter smaller than the body section 57.
The retainer portion 70 may stand proud of the belt element 20, or may be partially or fully countersunk into a recess 80 in the driving side 24 of the belt element 20. In an embodiment, the countersunk position of the retainer portion is achieved by a combination of an interruption in the surface feature 26 (e.g. ribs 26b) and the recess 80.
The pin 40 may need to exhibit a variety of characteristics regarding flexibility and rigidity to ensure an appropriate engagement with the materials and objects to be conveyed whilst remaining securely attached to the belt element 20. The desired characteristics may be achieved by a combination of the materials used and geometries of the various portions. A desired characteristic of the conveying side 50 may be a degree of flexibility to deform upon contact with the object/material to be conveyed. A desired characteristic of that portion of the pin 40 that passes through the aperture 30 during assembly, for example the first end 55, may be resilience such that it can be deformed to conform to the size of its corresponding aperture 30 during the fitting process and expand to a larger size, e.g. its original size, once the pin 40 is fully fitted in its corresponding aperture 30. A characteristic of the retainer portion 70 may be stiffness to prevent it from deforming and slipping into its corresponding aperture 30. Alternatively, or in addition, the cross-sectional diameter can be significantly oversized relative to its corresponding aperture 30 such that a relatively flexible retainer portion 70 will still not slip into its corresponding aperture 30. A relatively flexible retainer portion 70 may aid in a smooth driving of the conveyor belt 15 given the that the retainer portion 70 in that case can at least partially adapt to the form of a drive pulley/element.
In an embodiment the pin 40 is constructed from a single material and the geometry of the various sections are the main contributor to the behavioral characteristics of the pin 40. In an embodiment the pin 40 is constructed from a combination of materials. Suitable materials to be used in the construction of the pin 40 may be rubber, plastic and / or thermoplastic elastomers. The conveyor belt system 10 may include a plurality of differently configured pins 40.
Different configurations may include a mix of pins 40 having different sized or shapes or pins 40 distributed in a mix of multiple patterns and/or spacings.
