Definitions
- the present invention relates to a link chain for a link chain conveyor for transporting objects in the beverage, food and pharmaceutical industries.
- the link chain has a plurality of interconnected links.
- the tops of the chain links define a transport surface for the transportation of standing objects.
- the invention further relates to a link chain conveyor with such a link chain.
- link chain conveyors For the transport of objects in the beverage, food and pharmaceutical industries, such as commercial bottles, link chain conveyors are used. Such link chain conveyors are described for example in EP 0 545 398 A1.
- the link chains are stretched between two pulleys and thus define a transport path for objects.
- the link chains have a multiplicity of interconnected chain links, these chain links running along a guideway.
- rollers are provided which are associated with the individual chain links. These rollers allow the individual chain links to roll along the guideway. Thus, the friction between the individual chain links and the guideway is reduced.
- the present application therefore has the object of further developing a link chain used in a link chain conveyor as well as the link chain conveyor itself so as to eliminate or at least reduce the above-mentioned problems.
- a link chain for a link chain conveyor is proposed for transporting objects in the beverage, food and pharmaceutical industries.
- the link chain has a plurality of linked chain links.
- the upper sides of the chain links define a transport surface for the transport of stationary objects.
- the chain links each comprise a bicomponent roller, each bicomponent roller having an inner sliding component and an outer rolling component.
- the formation of the chain links, each with at least one roller which has two components solves the above-mentioned problems, since the inner sliding component can be formed so that only a low friction and a low wear between see the storage of the roll and the roll itself occurs.
- the outer rolling-off component can be made softer, so that the damping properties of the softer material can be utilized. More specifically, the outer rolling component produces less noise or less noise when used in a link chain conveyor. In addition, the adhesion between the roller and a guide track of the link chain conveyor is improved.
- rollers each consisting of two or more materials
- the roller properties at the roller-axis and roller-base interfaces can be optimally adapted to the respective transport environment.
- the material of the inner sliding component can be selected so that the bearing friction occurring reduces and the service life of the rollers is thereby extended.
- the outer rolling component can be optimized to reduce the friction between the roller and the track, or to counteract the causes of noise nuisance. Due to the independent choice of materials for the roll according to the invention an optimal role can be provided for each transport device or each transport task.
- tops of the chain links advantageously define a substantially closed transport surface for the transportation of standing objects.
- a wedge-shaped gap can be provided between the individual chain links in order to achieve sufficient rotatability between the chain links.
- the inner sliding component preferably has a greater modulus of elasticity than the outer rolling-off component.
- the inner sliding component has a modulus of elasticity which corresponds approximately to the elastic modulus of hard plastic or steel.
- the outer unwinding component may have a modulus of elasticity that approximately corresponds to the modulus of elasticity of hard rubber.
- the inner sliding component may be made of plastics such as polyethylene (PE), polyamide (PA), polyethylene terephthalate (PET), polyoxymethylene (POM), polyphenylene sulfide (PPS) or polypropylene. These materials may be slip-modified in order to improve their sliding properties.
- the inner sliding component can also be made of special sliding bearing materials, such as metallic sliding bearing materials.
- the outer unwinding component can be made of any of the elastomers known in the art, such as acrylonitrile-butadiene rubber (NBR), ethylene-propylene-diene (monomer) rubber (EPDN), fluororubber (FKM), chloroprene rubber (CR) or be made of other rubber or hard rubber materials.
- the inner sliding component may have a Young's modulus of 50 to 250 GPa, preferably 100 to 200 GPa, and more preferably 150 GPa.
- the outer rolling component may have a modulus of elasticity of 0.1 to 10 GPa, preferably 1 to 5 GPa, and more preferably 3 GPa.
- the actual moduli of elasticity of the abovementioned materials can deviate from these parameter ranges, since their moduli of elasticity also depends, for example, on the additives used, on the water absorption capacity or on the temperature under operating conditions.
- the inner sliding component and the outer rolling component are preferably arranged coaxially with respect to the axis of the two-component roller and have the shape of a hollow cylinder.
- the outer rolling-off component is preferably arranged directly adjacent to the inner sliding component.
- the two-component roll can be designed as an integral component.
- the two-component roll can be produced in a coextrusion process using a first material to form the inner sliding component and a second material forming the first material surrounding the outer rolling component.
- the individual chain links are dimensioned so that the rollers do not project beyond the lateral edge of the chain links.
- a lateral protrusion of the rollers can lead to additional friction.
- Such limiting elements, such as lateral partitions, are used in particular in curved areas in order to keep the link chains on a predetermined transport path.
- additional friction of the rollers on the lateral boundary walls again leads to increased wear and is therefore already to be avoided for this reason.
- rollers adjacent arranged link chains do not come into contact with each other.
- the rollers are received in recesses in the chain links, wherein the rollers protrude only on the underside of the chain links to allow unwinding of the chain links on a guideway.
- the chain links thus also serve to protect the rollers, since the rollers are then exposed only to the underside of the links of the environment. A friction with the sides of the chain links arranged elements of the transport device can thus be effectively prevented.
- the present application further proposes a link chain conveyor for transporting objects in the food and beverage industry.
- Objects within the meaning of the present invention can be containers such as glass bottles, plastic bottles, containers, containers sen, containers or other packages.
- the link chain conveyor has a link chain as described above and a guide track for guiding the chain links of the link chain.
- the chain links each have the two-component rollers in such a way that the chain links are arranged rolling along the guide track.
- the use of a single two-component roller is sufficient to achieve the above-mentioned advantages.
- the two-component roller must be made relatively wide in order to ensure a stable support of the chain link on the guide track of the link chain conveyor.
- the two-component roller is in this case advantageously arranged centrally with respect to the chain link, so that the chain link is mounted centrally on the two-component roller.
- the link chain conveyor is not designed as a linear conveyor, but direction changes are provided, a secure mounting of the chain links in relation to the guideway is necessary.
- a single, wide two-component roll may be subject to high wear.
- the guide track of the link chain conveyor is designed so that the two bicomponent rollers can roll in parallel on corresponding running surfaces of the guide track.
- the running direction of the link chain conveyor defines a direction of rotation axis.
- the two bicomponent rollers are arranged with respect to the running axis of the link chain conveyor so that the first two-component roller is arranged in the running direction to the left of the running axis of the link chain conveyor and the second two-component roller is arranged in the running direction to the right of the running direction axis of the link chain conveyor.
- the two-component rollers are arranged in the edge region or laterally of the chain link, so that a stable support of the chain link is ensured in the guide track of the link chain conveyor.
- the rollers do not project beyond the lateral edge of the link chains. In this way it can be avoided that the rollers rub against parts of the side boundary of the guideway. Such friction is to be avoided especially in the curved areas of guideways of the link chain conveyor.
- the individual two-component rollers can be made thinner or less wide in this case, so that a secure support of the chain links is achieved, in particular in curved areas of the link chain conveyor, and beyond that the wear of the two-component rollers is reduced.
- the two-component rollers are preferably rotatably supported independently of one another.
- the two bicomponent rollers may have a common axis, preferably in the form of a bolt, but each individual bicomponent roller is independently supported relative to the common axis.
- the inner sliding component may be formed as a hollow cylinder with a central
- the inner sliding component may also have a different shape.
- the inner sliding component may have a C-shaped cross-section such that the inner sliding component contacts the axle only in the axially outer portions.
- the contact surface can also be specifically dimensioned so that desired friction conditions can be set.
- the inner sliding component can generally be shaped so that it rests against the axle only in certain subregions. As a result, a desired friction behavior of the roller can be adjusted in a targeted manner.
- the axis formed as a bolt is preferably used for the storage of Zweikompo- nentenrollen with respect to the chain link and further for connecting two chain links.
- adjacent chain links on holding elements which engage with each other when the chain links are placed side by side.
- the two-component rollers are placed laterally next to the support members and the bolt pushed through corresponding recesses by the two-component rollers and the support members of the chain links.
- the two-component rollers can rotate independently of each other around the bolt.
- the support elements of the chain links and in particular the recesses of the chain links are preferably formed such that the chain links have some play, so that the chain links can move easily to each other and thereby the link chain curves and curves can describe.

- the two-component roller 10 shown in FIG. 1 has an inner sliding component 12 and an outer rolling component 14.
- the inner sliding component 12 has the shape of a coaxially arranged hollow cylinder. Inside the inner sliding component 12, a central bore 16 is formed, by means of which the two-component roller 10 can be mounted on an axle 18.
- the inner sliding component 12 is formed of a high modulus material such as plastic or steel.
- the outer rolling component 14 has a lower modulus of elasticity than the inner sliding component 12.
- the outer rolling component 14 is made of hard rubber.
- the outer periphery of the outer rolling component 14 forms a tread 19.
- FIG. 2 shows the use of the two-component roller 10 according to the invention in a link chain conveyor 20.
- the link chain conveyor 20 has a plurality of interconnected chain links 22.
- the chain links 22 are formed of metal or plastic. In the sectional view shown in Figure 2, a single chain link 22 is shown. On the chain link 22, not shown objects such. As bottles or the like can be transported.
- the chain link 22 is connected via a holder 24 and via an axle 18 in the form of a bolt with two two-component rollers 10 according to the invention.
- the axis 18 is through the holder 24 and the two-component rollers 10th pushed so that the two-component rollers 10 can rotate independently about the axis 18.
- FIG. 1 a guide track 26 of the link chain conveyor 20 is shown in FIG.
- the two-component rollers 10 rest on the guide track 26 of the link chain conveyor 20 so that the chain links 22 can roll over the two-component rollers 10 on the guide track 26 of the link chain conveyor 20.
- the link chain conveyor 20 may each have a guide track 26 for each of the bicomponent rollers 10 so that a bicomponent reel 10 rests on a left hand web and a bicomponent reel on a right hand run. Between the guide tracks 26, a guide recess 28 may be arranged, by means of which the chain links 22 can be guided.
- each chain link 22 may have a guide element which engages in the guide recess 28 (not shown in FIG. 2).
- FIGs 3 and 4 another embodiment of a link chain conveyor 20 according to the present invention is shown.
- the link chain conveyor 20 consists of a plurality of chain links 22, wherein in Figures 3 and 4, only two or four chain links 22 are shown.
- Each chain link 22 has an upper surface which defines a transport surface for the objects to be transported.
- the chain links 22 are interconnected by means of bolts.
- the bolts serve as axes 18 for supporting a respective pair of two-component rollers 10, which again each have an inner sliding component 12 and an outer rolling component 14.
- FIG. 4 shows a bottom view of the chain links 22.
- the rollers 10 are received in recesses of the chain links 22.
- the recesses surround the rollers 10 laterally, front and top completely, so that the rollers 10 are substantially accessible only from below and from behind.
- the roles are protected on the one hand.
- the axes 18 are positively and / or non-positively received in the areas 30 of the individual chain links 22.
- the respective subsequent in the transport direction chain link 22 is rotatably mounted with its nose 32 about the axes 18. This gives the link chain the flexibility needed so that the link chain can be performed endlessly over the provided at the end of a transport path pulleys.
- the nose 32 can also be designed in each case so that it allows a slight lateral deflection of the chain links 22, whereby a Kurveninkeit the link chain is achieved. Apart from the minor wedge-shaped gaps that can be seen between the chain links 22 in Fig. 4, the tops of the chain links form one Closed transport surface suitable for transporting stationary objects.
- the link chain is guided over two pulleys (not shown), which are provided at the beginning or at the end of the conveyor line.
- the deflection pulley arranged at the end of the conveying path also serves to drive the link chain at the same time.
- this pulley is designed as a gear.
- the teeth of this deflection roller can engage in the recesses 34, which are provided on the underside of each chain link 22.
- the two-component rollers 10, in particular the inner sliding component 12 of the two-component rollers, may also have recesses 36, so that the inner sliding component 12 does not bear on the axis 18 over the entire axial length.
- FIG. 5 shows by way of example a two-component roller 10, in which the inner sliding component 12 has a C-shaped profile. As a result, in this two-component roller 10, only the lateral ends of the inner sliding component 12 rest against the axle 18. By reducing the contact surface and the sliding friction occurring between the inner sliding component 12 and the axis 18 is reduced.
