Abstract
The present invention relates to an assembly for nesting tyres or the like, comprising:
- positioning means for positioning at least one first tyre;
- compressing means for compressing at least one second tyre; and
- placing means for placing the thus compressed second tyre in the positioned first tyre, so that the second tyre nests in the first tyre.
Description
- The present invention relates to an assembly for nesting tyres or the like and a method therefor.
- Businesses have been built up wherein used tyres are collected and transported to other parts of the world, such as countries in South America and Africa, where these tyres are then fitted again on vehicles for further use. Often in these countries tyres do not have to comply with strict legal requirements, which means that it is not illegal to drive on these used tyres.
- At present, these used tyres are collected and loaded in containers for transport. In order to increase the number of tyres which can be loaded in a container, tyres can be nested into each other, a process which at the moment is carried out manually. Problems associated herewith are that this is physically demanding, wasteful of energy, time-consuming and inefficient.
- An object of the present invention is to obviate at least one of these problems.
- According to a first aspect of the present invention an assembly is provided for nesting tyres or the like, comprising positioning means for positioning at least one first tyre, compressing means for compressing at least one second tyre and placing means for placing the thus compressed second tyre inside the positioned first tyre, so that the second tyre nests in the first tyre.
- Since the assembly according to the present invention automatically places one tyre into the other, the problems of nesting tyres manually are thus obviated.
- According to a second aspect of the present invention a method is provided for automatically nesting tyres or the like, which is performed by the above stated assembly, wherein the method comprises the steps of positioning at least one first tyre in a desired position; exerting compression force on at least one second tyre in order to compress same; and placing the thus compressed second tyre into the first tyre, so that the second tyre nests in the first tyre, whereafter this method can be repeated to nest further tyres inside the nested first and second tyre or for a further first and second tyre.
- According to a third aspect of the present invention a device is provided for automatically positioning and pulling apart at least one tyre, comprising positioning means for positioning the tyre and pulling apart means for pulling apart the tyre.
- According to a fourth aspect of the present invention an automatic method is provided for positioning and pulling apart at least one tyre which is performed by the above stated device, comprising the steps of positioning at least one tyre in a desired position, whereafter this tyre is pulled apart.
- According to a fifth aspect of the present invention a device is provided for compressing at least one tyre, wherein this device comprises at least one pointed compressing element and at least one rounded compressing element.
- According to a sixth aspect of the present invention an automatic method is provided for compressing at least one tyre, comprising the steps of compressing a tyre, wherein this process is performed by the above stated compressing device.
- Further details, features and advantages of the present invention follow in the form of a non-limiting description in which reference is made to the annexed figures, in which:
- figure 1 shows a perspective view of a preferred embodiment of the assembly according to the present invention;
- figure 2 shows a partly broken away front view in perspective of the assembly of figure 1;
- figures 3-10 show broken away exploded front views in perspective of parts of the assembly of figures 1 and 2, wherein the operation of the assembly is shown schematically.
- An assembly 1 (figure 1) according to the present invention preferably has transport means, preferably in the form of a
first conveyer belt 2 for transporting to the interior of the assembly tyres in which other tyres have to be nested, which assembly 1 preferably stands inside a housing 3. - A
pneumatic press 4 is mounted on top of the assembly 1 (see figures 1-10). The assembly 1 preferably has anaccess 5 through which tyres which have to be compressed can be introduced into the assembly 1. Thisaccess 5 is preferably provided with a displaceable safety fence (not shown). - Access to the assembly 1 is preferably made possible through a door 6 arranged in the housing 3.
- When a tyre A is placed on
conveyer belt 2, tyre A is transported inside the assembly and up to the positioning means, which are preferably formed by a bench element 7 (see figures 2-10), at whichposition conveyer belt 2 receives a signal to stop. - Once the tyre A has been placed on
bench element 7, the latter is automatically displaced upward, preferably via a pneumatic piston arm. During displacement thisbench element 7 is preferably stabilized byrods 9 arranged in the assembly which are situated close to the corners ofbench element 7. This combination of the pneumatic piston arm 8 and therods 9 enables a smooth upward and downward movement ofbench element 7. - Two lower pulling apart
members 10 are mounted onbench element 7. When the tyre A lies onbench element 7 thelips 11 of the lower pulling apartmembers 10 fit over the inner edge of the tyre A (see figures 2-4). - The tyre A is then carried upward via
bench element 7 until the upper pulling apartmembers 12 pass into the tyre opposite the lower pulling apart members 10 (see figure 4). - The lower pulling apart
members 10 are then moved apart from their rest position by pneumatically controllable rods 13 (figure 5) until thelips 11 of the lower pulling apart members engage the inside of tyre A. At the same time the upper pulling apartmembers 12 are displaced pneumatically so that they come to lie in line with anopening 14 in anupper platform 15 of assembly 1. In this position thelips 16 of the upper pulling apartmembers 12 also push against the inside of the tyre A (see figure 5). - The
bench element 7 is then carried slightly downward so that thelips 11 of lower pulling apartmembers 10 and thelips 16 of upper pulling apartmembers 12 push against the interior side of tyre A, whereby this is pulled apart and held fast (see figure 6). - A second tyre B which has been introduced into the assembly via the
access 5 so as to lie above theopening 14 in upper platform 15 (see figure 7) is enclosed in this position by four pointedcompressing elements 17 and four rounded compressing elements 18 (see figures 2 and 7). The pointedcompressing elements 17 are pressed first into the tyre B (see figure 8). The roundedcompressing elements 18 are subsequently pressed inward so that the tyre B assumes a form and size as shown in figure 9 which enables the tyre to pass throughopening 14. - The
compressing element 17 respectively 18 is preferably operated by pneumatic rods 20 respectively 21. - The shape of the
compressing elements 17 respectively 18 and the sequence in which these are pressed together was developed after extensive research in order to ensure that the flipping out of position of a tyre during compression is minimized (see figure 8). - The compressed tyre B is subsequently placed in the tyre A which has been pulled apart by pushing tyre B with force through the opening 14, this being performed by the
press 4. Since thecompressing elements 17 respectively 18 moved toward each other and the upper pulling apartmembers 12 form a sort of passage, the compressed tyre B does not spring out of its compressed shape until it has been placed inside the tyre A, i.e. after tyre B has been pressed past thelips 16 of upper pulling apartmembers 12. In this position the tyre B springs out of its compressed shape, so that it nests inside the tyre A which has been pulled apart. Thepress 4 preferably remains in its lowered position (as shown in figure 10) for at least one second, so that the compressed tyre B can nest inside the pulled apart tyre A without the compressed tyre B springing in upward direction and thereby possibly causing complications in the nesting thereof. - Prior to the actual compressing of a tyre, the
compressing elements 18 respectively 19 are preferably sprayed, preferably with water, in order to facilitate forcing of compressed tyres into the pulled apart tyres, for instance in unfavorable weather conditions. - The
bench element 7 is thereafter moved upward to support the now nested tyres A and B, whereafter the pulling apartmembers 10 respectively 11 are retracted to their rest positions. - The
bench element 7 is then carried downward, whereafter the nested tyres are transported out of the assembly 1, preferably by a second conveyer belt 19 (see figure 2). - The assembly according to the present invention is very suitable for placing smaller tyres of for instance thirteen inches inside larger tyres of for instance fourteen inches. Using the assembly according to the present invention approximately 300 tyres per hour can be placed inside other tyres, while it takes a single employee about five days to place 250 tyres inside other tyres. A container can thus be loaded more quickly with more tyres with use of an assembly according to the present invention than in the case of nested tyres which have to be nested manually beforehand.
- It is also possible with an assembly according to the present invention to place a third tyre inside the now nested first and second tyre. In this case, after two tyres have been nested, the now "doubled tyres" are pulled apart and a compressed third tyre is placed therein.
- The operation of the assembly according to the present invention is preferably controlled by a computer in order to facilitate the process of/for nesting tyres.
