The surface of the belt 26 may be textured, profiled, dimpled or pimpled (40 fig. 5) or may be provided with a coating (44 fig. 6) of silicone, stearate or fatty acids or polytetrafluoroethylene. The apparatus may be used to splice the leading end 22 of the reel of material 16 to the material of a first reel of material 4 with a flying splice to allow it to be fed to a downstream apparatus such as a printing press 14.

Description

BELT DRIVEN REEL STAND

The present invention relates to a belt driven reel stand, and apparatus and methods related to such a belt driven reel stand.

A reel stand is a stand on which a reel of material may be mounted. Rotation of the reel may be undertaken to deliver material of the reel to other apparatus, for example a downstream printing press, or other apparatus. For reels of a relatively small size, rotation of the reel may be achieved by appropriate driving of a shaft on which the reel is mounted.

However, when the size of the reel is greater, and for example in excess of 1.5m in width, it may be more practical, or easier, to drive rotation of the reel by driving a belt that is in contact with an external surface of the reel, for example along an external circumference thereof. The belt itself may be driven by rotation of rollers, or wheels, or the like, on which the belt is mounted.

When a reel of material is used, over time the amount of material on the reel will decrease, and it may become necessary to provide additional material to the process or apparatus fed by the reel. Material may be provided by undertaking a reel change, which may be described, alternatively or additionally, as providing material from a different reel. To eliminate or avoid reductions in throughput, it is desirable to provide additional material without stopping the downstream apparatus or process. To achieve this, material from a new reel may be spliced with material of the existing reel, for example using a festoon splice, or a flying splice. A flying splice is undertaken when the existing reel and new reel are rotating at substantially the same speed, usually at an operating speed of the reel that is providing material to the downstream apparatus or process. Flying splice is often used in situations where high throughput is required, often with larger reel sizes.

In order to perform a flying splice, the new reel is provided with adhesive which extends across an outer surface of the new reel. The adhesive is used in the splice to adhere the material of the new reel to material of the existing reel. More particularly, adhesive will usually be provided in the form of double sided adhesive tape. The adhesive retains a leading end of the material of the new reel on a main body of material of the reel, and also facilitates the attachment of that leading end to material of the existing reel during the flying splice.

During the flying splice, a procedure is undertaken whereby material from the existing reel is in some way brought into contact with the adhesive of the new reel to cause the material of a new reel to become joined with (that is, spliced) the material of the existing reel.

One or more cutting tools are then used to sever the material being fed by the existing reel, such that material is fed to the downstream process or apparatus from the new reel.

As discussed above, in a flying splice it is necessary to rotate the new reel at the same speed of rotation as that of the existing reel. One or more belts used to drive rotation of the new reel, and indeed the existing reel, will come into contact with the outer surface of the reel in question. As is standard practice throughout the industry, the one or more belts used to drive rotation of the reel cannot come into direct contact with adhesive on the reel, or the belt will pull at the adhesive and may cause damage or distortion to material on the reel. Direct contact' in this instance may be described as the situation where an entire cross-sectional area of the belt that rides across the adhesive contacts the same cross-sectional area of adhesive.

In an attempt to overcome the problems of distortion or damage, an industry-wide solution has been adopted over many decades. The solution is to provide tabs or areas of cover material on the adhesive in the locations where the belt rides across the adhesive.

Typically, the material of these cover areas will be substantially the same material as the material on the reel, or at the very least a material that is substantially inadhesive with respect to the belt.

The use of areas of cover material is a solution that has been adopted by the industry for many decades, and is taken by the industry to be the sole solution to the above-mentioned problem. Indeed, much innovation has occurred in this field with the aim of improving the performance of these cover areas, for example to further reduce distortion and/or damage to the material of the reel. The cover areas of material may be continuous, extending across the entire area of adhesive that would otherwise come into contact with the belt. In alternative examples, the areas of cover material may be provided with one or more cut outs, the cut outs being provided in an attempt to solve specific problems. For example, the cut outs may be provided to reduce distortion of the material of the reel that might otherwise be present due to the presence of the cover material on the adhesive. The areas of cover material may be provided with certain cut outs, or have certain specific shapes, areas, sizes, materials, or the like. However, and regardless of the extent of innovation in this area, problems still nevertheless remain with the use of such areas of cover material.

One problem is that the areas of cover material do not always work as intended, and might still result in damage or distortion to the material on the reel. This can be somewhat random in terms of occurrence and extent, and may depend on many relatively uncontrollable environmental factors, such as humidity, temperature and the like. Additionally, the application and effectiveness of areas of cover material are often directly related to a person who applies the cover material to the adhesive. If the area of cover material is even slightly misplaced, or misaligned, then distortion and damage to material of the reel may result. Even when the same person applies cover areas in the same way on different days, different results may arise due to the environmental factors mentioned previously.

A newly proposed alternative, but related, solution is to vary the layout (e.g. shape, size, distribution) of the adhesive that is applied to the reel, to affect the area of the adhesive that comes into contact with material of a new reel during a splice. However, this has the same or similar problems to that outlined above when discussing areas of cover material. Additionally, these layouts are time consuming to apply, and expensive to implement.

In summary, despite the large amount of innovation that has occurred in this field, problems still remain. The industry continues to seek solutions to these problems, and those solutions are being sought mainly in the development of cover areas of material that are applied to the adhesive, but also in the layout of the adhesive.

It is an aim of the example embodiments of the present invention to provide a belt driven reel stand, and/or related apparatus and methods, that obviate or mitigate at least one disadvantage of the prior art, whether identified herein or elsewhere, or which provide an alternative to existing apparatus and/or methods.

According to the present invention there is provided an apparatus and method as set forth in the appended claims. Other features of the invention will be apparent from the dependent claims, and the description which follows.

According to a first aspect of the invention, there is provided a belt driven reel stand apparatus comprising: a stand for holding a reel of material, wherein in use the reel of material is provided with a layer of adhesive extending across an outer surface of the reel of material, the adhesive being adhesive at least with respect to material forming the reel of material; and a driveable belt for driving rotation of the reel of material, wherein a surface of the belt that is arranged, in use, to contact the reel is configured to be substantially inadhesive with respect to the adhesive that extends across the outer surface of the reel of material.

The surface of the belt that is arranged, in use, to contact the reel may be textured, the texture being arranged to ensure that the belt is substantially inadhesive with respect to the adhesive that extends across the outer surface of the reel.

The texture may be a profiled surface, for example one that reduces a contact area between the surface and the reel/adhesive in comparison with a flat, un-profiled belt.

The surface of the belt that is arranged, in use, to contact the reel may be provided with a coating, the coating being arranged to ensure that the belt is substantially inadhesive with respect to the adhesive that extends across the outer surface of the reel.

The coating may comprise one or more of: silicone, stearate or fatty acids, or polytetrafluoroethylene.

The belt may be formed from a material that is substantially inadhesive with respect to the adhesive that extends across the outer surface of the reel.

The belt material may comprise one or more of: silicone, stearate or fatty acids, or polytetrafluoroethylene.

The surface of the belt that is configured to be substantially inadhesive with respect to the adhesive that extends across the outer surface of the reel, may be substantially inadhesive, in so far as that the adhesion is less than the adhesion between a flat rubber or leather belt surface, and an acrylic based adhesive. The adhesion may less than 75%, less than 50%, or less than 25%.

According to a second aspect of the invention, there is provided a flying splice apparatus, which comprises the belt driven reel stand apparatus of the first aspect of the invention.

According to a third aspect of the invention, there is provided a printing press apparatus, comprising, or configured to be in connection with (e.g. to be fed with material from), the belt driven reel stand apparatus, and/or the flying splice apparatus, of the first and/or second aspect of the invention.

According to a fourth aspect of the invention, there is provided a method of rotating a reel of material about a longitudinal axis of that reel, the reel of material being provided with a layer of adhesive extending across an outer surface of the reel, the adhesive being adhesive at least with respect to material forming the reel, the method comprising: driving a belt that is in contact with the reel of material, wherein a surface of the belt that contacts the reel is configured to be substantially inadeshive with respect to the adhesive that extends across the outer surface of the reel.

According to any aspect of the invention, the adhesive may be for: adhering a leading end of the reel of material to a body of material on the reel; and/or splicing material of the reel with material of a separate reel.

According to any aspect of the invention, in use, during rotation of the reel, an entire cross-sectional area of the belt that rides across the adhesive may contact the same cross sectional-area of adhesive.

According to a fifth aspect of the invention, there is provided a method of rotating a reel of material about a longitudinal axis of that reel, the reel of material being provided with a layer of adhesive extending across an outer surface of the reel, the adhesive being adhesive at least with respect to material forming the reel, the method comprising: driving a belt that is in contact with the reel of material, wherein during rotation of the reel, an entire cross-sectional area of the belt that rides across the adhesive contacts the same cross-sectional area of adhesive.

According to a sixth aspect of the invention, there is provided a belt driven reel stand assembly comprising: a reel of material provided with a layer of adhesive extending across an outer surface of the reel, the adhesive being adhesive at least with respect to material forming the reel; a stand for holding the reel; and a driveable belt for driving rotation of the reel of material, wherein the assembly is configured to ensure that, in use, during rotation of the reel, an entire cross-sectional area of the belt that rides across the adhesive contacts the same cross-sectional area of adhesive.

Where appropriate, one or more features of one or more aspects of the invention may be used in combination with, or in replacement of, one or more features of one or more other aspects of the invention.

For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which: Figure 1 schematically depicts a printing press apparatus, comprising a flying splice apparatus having a belt driven reel stand apparatus, in accordance with an example embodiment of the present invention; Figure 2 schematically depicts a reel of material provided with adhesive extending across an external surface of that reel of material; Figure 3 schematically depicts the use of areas of cover material on adhesive provided on a reel of material, relative to the location of belts used to drive rotation of the reel of material; Figure 4 schematically depicts the driving of the rotation of a reel of material using belts that directly contact the adhesive, in accordance with an example embodiment of the present invention; and Figures 5 to 7 schematically depict different belt configurations for driving rotation of a reel of material, in accordance with example embodiments of the present invention.

The same features appearing in different Figures have been given the same reference numerals for consistency and clarity.

As discussed above, it is an industry wide approach to apply areas of cover material to areas of adhesive over which drive belts will ride. According to example embodiments of the present invention, it has been realised that it is not necessarily the specific application, orientation, layout, configuration, or composition of areas of cover material that causes the problems of distortion and/or damage to material on the reel when that reel is rotated by belts.

Instead, it is the use of such areas of cover material in general. That is, according to example embodiments of the present invention, such areas of material are not used. Instead, example embodiments of the present invention take a completely opposite approach to that adopted across the industry, and opposite to the approach that has been adopted for many decades in that industry. According to example embodiments, the approach is to allow the belts to ride over the adhesive, and in direct contact with the adhesive, but to ensure that the surface of the belt that contacts the reel is configured to be substantially inadhesive with respect to the adhesive that extends across the outer surface of the reel. This facilitates the rotation of the reel in such a way where an entire cross-sectional area of the belt that rides across the location of the adhesive contacts the same cross-sectional area of adhesive -i.e. there is no cover material separating the adhesive from the belt, as is the case in all prior art solutions. It has been found that this significantly reduces the amount of distortion and/or damage caused to material forming the reel due to interaction that might otherwise take place between the belt and the adhesive. Splicing is thus improved, as is the quality of any product using the material.

Shutdowns that might otherwise be required to rectify problems associated with distortion or damage of reel material are reduced, increasing throughput. The time otherwise taken to apply the areas of cover material might also be used for more useful purposes, improving efficiency.

Example embodiments of the present invention do not necessarily relate to the provision of a belt having a particular configuration that is substantially inadhesive with respect to a particular adhesive. Instead, the result to be achieved by the present invention is to reduce or eliminate distortion or damage to the material forming the reel as a consequence of interaction of the belt with the reel. The invention might be understood to be at least partially defined by the broad realisation that a substantially opposite approach to a long-standing and industry-wide approach is adopted. The solution provided is to ensure that the belt is substantially inadhesive with respect to the adhesive that is used. Once the realisation and solution is apparent to the skilled person from this disclosure, various solutions specific to the configuration of the belt relative to the adhesive would become apparent. It will of course be appreciated that it would be impractical to provide here every single bell configuration that is substantially inadhesive with respect to every single adhesive that might be used. The invention is defined by a broader, functional principle.

Example embodiments of the present invention will now be described, by way of example only, with reference to Figures ito 7.

Figure 1 schematically depicts a belt driven reel stand apparatus. The apparatus comprises a first stand (2) for holding a first reel of material (4). The first reel of material (4) may be held by the stand (2) via a shaft (6) that extends through the first reel of material (4).

In an alternative (not shown), the reel may be held via chucks extending part way into the opposite ends of the reel.

The first reel of material (4) may be rotated using a belt (8) that is in contact with the first reel of material (4). The belt may be driven by any convenient means, for example using one or more driving rollers (10), or wheel or the like. In use, the belt (8) may be driven to drive rotation of the first reel of material (4). A leading end (12) of the first reel of material (4) is fed into downstream apparatus, for example a printing press as schematically depicted by a box (14). It will be appreciated that in other embodiments the apparatus to which material is fed may not be a printing press, but for example could be any arrangement that is fed with material from a reel of material.

As the material on the first reel of material (4) becomes depleted in used, it will at some point become necessary to replace the first reel of material with a second reel of material (16).

The second reel of material (16) may be held via a shaft (18) extending through the reel (16) via a second reel stand (20). In an alternative (not shown), the reel may be held via chucks extending part way into the opposite ends of the reel.

The replacement' might be more accurately described as splicing material from the second, new, reel of material (16) with expiring material on the first reel of material (4) to ensure that the, for example, printing press (14) is continuously provided with a supply of material. The splice will typically be a flying splice, where belt driven reel stands are typically used.

Before undertaking a flying splice using a leading end (22) of material of the second reel of material (16), the second reel of material (16) may be rotated to substantially match the speed of rotation of the first reel of material (4). Rotation of the second reel of material (16) may be undertaken in much the same way as rotation of the first reel of material (4). The rotation will be undertaken by driving rollers (24) or wheels or the like, which in turn drive a bell (26) that is in contact with the second reel of material (16).

The flying splice may be undertaken by appropriate movement of one or more of the first reel stand (2), first reel of material (4), second reel stand (20), or second reel of material (16) relative to one another (indicated by arrow (28)). The movement is to bring the leading end (22) of material of the second reel of material (16) into contact with material on the first reel of material (4), to splice the materials of the different reels (4, 16) together to maintain a supply of material to the printing press (14).

Figure 2 shows that the second reel of material (16) (in this example) may be provided with a layer of adhesive (30) that extends across an outer surface of the reel (16). The adhesive (30) is used to facilitate the splicing of the leading end (22) of the second reel of material (16) with the first reel of material, as discussed above. The adhesive (30) also ensures that, during rotation of the second reel of material (16), the leading end (22) of the reel of material remains substantially attached to the main body (32) of the reel (16). This prevents damage to the leading end (22), and any associated jamming of apparatus that might be cause by a flailing leading end (22). The layer of adhesive is typically provided in the form of a tape (for instance a double-sided piece of tape). The adhesive (30) typically extends across substantially the entire width of the reel (16).

Figure 3 shows the location of belts (26) used to drive rotation of the reel (16). Shown in dashed outline (34) are the areas of the reel (16) that will come into contact with the belts (26) during rotation of the reel (16). In accordance with existing, prior art, decade long and industry wide principles, the adhesive (30) may be substantially prevented from coming into contact with and sticking to the bells (26) by use of areas of cover material (36) located on the adhesive, and which span the areas of the adhesive over which the belts (26) would ride. As discussed above, the use of cover areas may be probleniatic.

Figure 4 shows that, in accordance with example embodiments of the present invention, the areas of cover material shown in Figure 3 are no longer required, such that the problems associated with use of such cover material may be reduced or avoided. Figure 4 shows that the belts (26) ride directly over the adhesive (30). There is no material located between the adhesive (30) and the belts (26). That is, during rotation of the reel (16) an entire cross-sectional area of the belts (26) that ride across a location of adhesive come in to contact with the very same cross-sectional area of adhesive (30). This is completely opposite to the principles as shown in and described with reference to Figure 3, as discussed in more detail further above.

Allowing the belt (26) to come into contact with the adhesive (30), and without causing any or significant distortion or damage to the material on the reel (16), may be at least partially facilitated by ensuring that the surface of the belts (26) that contact the reel (16) are configured to be substantially inadhesive with respect to the adhesive (30). Ensuring that the surfaces of the belts (26) that come into contact with the reel (16) and adhesive (30) are substantially inadhesive with respect to that adhesive (30) may be achieved in a number of ways. For example, this may be achieved by reducing chemical bonding, reducing surface energy, or reducing surface contact area.

Figure 5 shows that a belt (38) may be textured (40), the texture being arranged to ensure that the belt (38) is substantially inadhesive with respect to the adhesive that extends across the outer surface of the reel. Figure 5 shows that the texture takes the form of a plurality of dimples (or pimples) distributed across a surface of the belt (38). Other texturing examples are also possible. The texture may be any profiled surface, for example one that reduces a contact area between the surface and the reel/adhesive in comparison with a flat, un-profiled belt. The texture is a deliberate, functional texture, as opposed to any defect in a flat belt, or a texture that is inherent in the material of the belt. The profile should be such that there is, in use, sufficient friction to drive the reel without slipping. A textured belt (38) may allow standard materials to be used, which might be advantageous.

Figure 6 shows another belt (42), in this instance provided with a coating (44) that is arranged to ensure the belt (42) is substantially inadhesive with respect to adhesive that extends across the outer surface of the reel. The coating may be, or may comprise, for example, silicone (e.g. silicone polymer), stearate or fatty acids, or polytetrafluoroethylene, which may work by reducing surface energy and preventing the adhesive adhering to the surface of the belt. A coated belt (42) may allow a non-textured belt to be used, which might be advantageous.

Figure 7 shows another belt (46), in this instance formed from a material that is substantially inadhesive with respect to the adhesive that extends across an outer surface of the reel. The material may be, or may comprise, for example, silicone (e.g. silicone polymer), stearate or fatty acids, or polytetrafluoroethylene, which may work by reducing surface energy and preventing the adhesive adhering to the surface of the belt.

One or more approaches to achieving the inadhesive nature of the belt may be used in isolation or combination. For instance, the belt may be provided with a texture to improve or ensure an inadhesive affect, and/or a coating that improves or ensures an inadhesive affect, and/or be formed, in general, from a material that ensures or improves an inadhesive affect.

As discussed above, in accordance with example embodiments of the present invention, the belt will be substantially inadhesive with respect to the adhesive that is used on the reel of material. The adhesion may be defined as being less than the adhesion between an industry standard belt and an industry standard adhesive, for example a belt having a flat reel contact surface comprising nitrile butadiene rubber, or any other form of rubber, or leather, and an adhesive such as an acrylic based adhesive (possibly softened with resin of some form).

As discussed above, the present invention might be particularly applicable to the field of printing presses and related apparatus and methods, where the reels of material comprise reels of paper, and the apparatus with which the belt driven reel stands are used are most likely to be printing presses. This is because it is in this particular industry where the use of areas of material covering adhesive to prevent or limit the contact between the drive belts and the adhesive is most widespread, and has been widespread for a number of decades.

However, similar problems may exist in similar industries where rotation of the reel is undertaken using belts, and the invention might find use in those industries.

As already discussed above, it will be appreciated that it is impractical to provide each and every possible configuration for each and every belt that is substantially inadhesive with respect to each and every adhesive that may be used on a reel of material. The invention instead lies in the realisation that the use of areas of material on the adhesive to prevent contact between the belt and the adhesive, and/or particular adhesive layout patterns, is not an ideal solution, and that the invention takes the essentially opposite approach of providing a belt that is inadhesive with respect to the adhesive that is used. Once this disclosure has been made apparent to the skilled person, the skilled person, with that knowledge, would be able to provide a belt with a particular configuration for an adhesive of a particular type.
