Description

Title: Conveyor chain
The invention relates to a conveyor chain, comprising a series of sheet metal chain links successive in a conveying direction, which are each provided with a basically rectangular conveying body part and with a hinge system located below the conveying body part.
The hinge system usually comprises a central hinge loop on one longitudinal side of the conveying body part of the chain link and a pair of adjoining hinge loops spaced apart with an interspace on the opposite longitudinal side of the chain link, while the central hinge loop is located in the interspace of a successive chain link.
The hinge loops of chain links successive in conveying direction cooperate, and are coupled per hinge system with the aid of a hinge pin.
Such a conveyor chain is generally known and can be used for, for instance, conveying bottles, cans, etc., in, for instance, breweries, soft drink bottling plants, etc.
With the customary chain, the thickness of the sheet metal of the body part is approximately 2.9 mm— 3.1 mm, and the diameter of the hinge pin is approximately 6.0 mm— 6.4 mm. The standard width of the hinge system is approximately 41 - 43 mm, and the pitch of the chain links is approximately 1.5 inch. Such a type of chain is so customary that it has been normalised in DIN 8153/ISO 4348.
With wider conveyors, usually a number of parallel chain tracks are used. This has as a drawback that the conveyor becomes relatively costly.
The object of the invention is to provide an alternative conveyor chain, with which, while maintaining the advantages, the drawback mentioned can be obviated.
To that end, a conveyor chain according to the invention is characterized in that the chain links are furthermore provided with a further hinge system placed at an intermediate distance transversely to the conveying direction. By providing the chain links with two hinge systems spaced apart with an intermediate distance transversely to the conveying direction, with relatively limited costs, a strong, relatively wide conveyor chain can be realized, with which several parallel chain tracks can be filled simultaneously. Also, when compared to a number of parallel chain tracks, the stability of the products during conveyance can be increased.
The chain links can then, for instance, for the purpose of guiding be received with their hinge systems between wear strips of a track that is configured for several parallel narrow chain tracks. As an alternative, the chain links may for the purpose of guiding be confined between two wear strips spaced apart with a relatively large intermediate distance. Such a conveyor chain can be advantageously utilized in a pasteurizer or a similar apparatus comprising a tunnel-shaped housing through which are led a plurality of conveyor chains running side by side.
The second hinge system preferably comprises a second central hinge loop located transversely to the conveying direction with an intermediate distance from the first central hinge loop on the one longitudinal side of the conveying body part of the chain link, and a second pair of outer hinge loops spaced apart with an interspace, which is also located transversely to the conveying direction with an intermediate distance from the first pair of outer hinge loops on the opposite longitudinal side of the chain link. Advantageously, the hinge systems are each located near an end of the chain links. The interspace between the hinge systems is preferably greater than the dimension of the hinge system transverse to the conveying direction, in particular a multiple thereof.
Advantageously, the hinge systems are each provided with a separate hinge pin.
Further advantageous embodiments of the invention are
represented in the subclaims.
The invention also relates to a chain link. The invention will be further elucidated on the basis of an
exemplary embodiment which is represented in a drawing.
In the drawing:
Fig. 1 shows a schematic perspective top plan view of a conveyor chain according to the invention, and
Fig. 2 shows a perspective top plan view of a number of conveyor chains running side by side of Fig. 1 which are received in a specially configured guide track.
In the Figures, identical or corresponding parts are represented with the same reference numerals. The drawings are only schematic
representations of preferred embodiments of the invention which are given by way of non-limiting exemplary embodiment.
Fig. 1 shows a conveyor chain 1, comprising a series of sheet metal chain links 2. The chain links 2 are each provided with a basically rectangular conveying body part 3 and with a first hinge system 4 located below the conveying body part 3. The conveyor chain 1 is intended to be moved during use in a conveying direction represented with arrow P along a conveying track 5. The conveying track 5 supports the conveying body part 3 and is provided with a groove 6 for guiding the hinge system 4 therein.
In a manner known to the skilled person, the sheet metal chain links 2 are punched from sheet metal thereby forming the hinge loops. In this exemplary embodiment, the hinge loops 2 are manufactured from ferritic- pearlitic stainless steel, for instance with Werkstoff (material) number 1.4589, 1.4016 or 1.4017.
The first hinge system 4 comprises a central hinge loop 7 on one longitudinal side 8 of the conveying body part 3 of the chain link 2, and further a pair of outer hinge loops 10 spaced apart with an interspace 9 transversely to the conveying direction on the opposite longitudinal side 11 of the chain link 2. The central hinge loop is located in the interspace 9 of a successive chain link 2. The chain links 2 further comprise a second hinge system 4'. The second hinge system 4' comprises a second central hinge loop T which is located transversely to the conveying direction with an intermediate distance from the first central hinge loop 7 on the one longitudinal side of the conveying body part 8 of the chain link 2, and a second pair of outer hinge loops 10* spaced apart with an interspace 9' which is also located transversely to the conveying direction with an intermediate distance from the first pair of outer hinge loops 10 on the opposite longitudinal side 11 of the chain link 2.
The hinge systems 4, 4' are each located near an end of the chain link 2, and are spaced apart transversely to the conveying direction P with a multiple of the width of the hinge system.
The cooperating hinge loops 7, 10 of the first hinge system 4 and the hinge loops 7', 10', of the second hinge system 4' are coupled by means of separate steel binge pins 14, 14'. The hinge pins 14, 14' are preferably manufactured from stainless steel, but can also be manufactured from another material. The hinge pins 14, 14' are secured with a slightly clamping fit in the central hinge loops 7, T of the longitudinal side 8, while the hinge pins 14, 14' are secured with a loose fit in the pairs of outer hinge loops 10, 10* on the opposite side 11. As is shown here, it is preferred that together, the outer hinge loops 10, 10* on the opposite longitudinal side 11 have a substantially equal width on both sides, and together are preferably approximately as wide as the central hinge loop 7, 7'.
In this exemplary embodiment, the thickness of the sheet metal of the conveying body part is approximately 2.5 mm, and the diameter of the hinge pin is approximately 4.0 mm.
The width of each hinge system is approximately 42.2 mm, while in this example, the pitch between successive chain links is approximately 25.4 mm. Naturally, the pitch can be selected to be different, for instance 1.5" (approximately 38.1 mm). The length of the hinge pins 14, 14' is approximately 40 mm. In this exemplary embodiment, the material of the hinge pin is selected to have a composition of steel alloy which comprises more than approximately 0.6 wt.% of carbon, and approximately 15-19 wt.% of chromium. Such a type of material is described in NL 1023383 for the hinge pin. Other steel pin materials are pin materials with Werkstoff (material) numbers 1.4057, 1.4125 or 1.4462.
In Fig. 2, it is represented how the chain links 2 of a plurality of conveyor chains 1 running side by side can be confined by their hinge systems 4, 4' between two wear strips 15 spaced apart with a relatively great intermediate distance of a specially configured conveying track 5. Such a conveyor chain 1 can be advantageously used in a pasteurizer or similar apparatus comprising a tunnel-shaped housing through which a plurality of conveyor chains running side by side are led.
The invention is not limited to the exemplary embodiment represented here. For instance, the hinge pin may also be secured in the pair of loops on the opposite side, while the central hinge loop and the auxiliary hinge loops have a loose fit or an oversized fit. Further, the width of the hinge loops can be selected to be mutually unequal per side, for instance a relatively wide central hinge loop and narrower auxiliary hinge loops.
It will be clear to the skilled person that many variants are possible within the scope of the invention as set forth in the following claims.
