Definitions
- the present invention relates to a method for assembling a conveyor chain for a pallet belt of a moving walk, a method for exchanging a
- Moving walks are used as passenger transport systems to transport people within a building along a travel path that is generally horizontal or only slightly inclined.
- a moving walk has a pallet belt on which passengers can stand and which can be moved all the way along the travel path.
- a large number of pallets are arranged one behind the other on the pallet belt.
- each of the pallets is attached between two conveyor chains, which are arranged along opposite sides of the pallet belt.
- Each of the conveyor chains is in turn composed of a large number of elongated chain links which are arranged one behind the other at a pitch and are pivotally connected to one another via chain bolts, so that the entire conveyor chain can be subjected to high tensile loads.
- the pitch spacing essentially corresponds to the spacing of the central longitudinal axes of the chain pins.
- the pallet belt is arranged all around. This means that the pallets can be moved in a forward direction along the travel path using the conveyor chains. At the ends of the travel path, the pallet belt is deflected by deflection devices, so that the pallets with the ring-shaped closed pallet belt can be moved back in the opposite return direction to the beginning of the travel path.
- Corresponding deflection devices generally have deflection sprockets, each of which cooperates with one of the conveyor chains in order to deflect it generally from the forward direction into the return direction or vice versa by 180 °.
- a moving walk is to be installed in a new building to be built, provision can be made for at least parts of the moving walk to be integrated into a floor of the building, so that a running surface formed by the pallets in the lead can be as flush as possible with a surface of this floor.
- a moving walk is to be retrofitted in an existing structure, it may not be possible in some cases, for example for structural reasons, or at least very expensive to sink it at least partially into a floor of the building. In this case, the moving walk must be on the floor of the building being constructed.
- a height difference between a level on which the moving surface of the moving walk runs and a level of the surrounding floor should be as small as possible.
- the aim should be to use a moving walk with a particularly low overall height.
- the overall height of a moving walk is determined by the overall height of its
- Deflection devices and in particular determined by a diameter of the deflection sprockets, which are generally arranged vertically and used therein.
- so-called polygon effects can occur due to the fact that pallets of any size cannot be used, but rather that the pallets have a minimum length (measured in the direction of travel) for practical use.
- Such polygon effects can occur noticeably if the length of the pallets, and the associated spacing of the conveyor chain, are not sufficiently small compared to the diameter of the deflection sprockets.
- a minimum number of teeth of the deflection sprockets of 17 teeth and therefore a minimum overall height was not undercut in conventional moving walks.
- WO 2013/152714 A1 describes a pallet belt for use in a
- Conveyor system in particular a moving walk, described.
- the pallet belt described has two conveyor chains and pallets arranged between them. This
- Pallet belt can help to some extent due to its structural design, Limit polygon effects even when using small deflection sprockets.

Then several pallets are attached to the two conveyor chains, the pallets being arranged one behind the other in the direction of extension of the conveyor chains. Each of the pallets is fastened at a first lateral end to one of the connecting elements of the first conveyor chain and at an opposite second lateral end to one of the connecting elements of the second conveyor chain.
- the methods according to the invention enable structured and secure assembly of interlocking and overlapping elements or components of a conveyor chain or a pallet belt. These interlocking and overlapping elements ensure high operational reliability.
- the special design of the interlocking and overlapping elements also requires a structured procedure when exchanging elements.
- Embodiments of the invention are to be regarded as based on the ideas and knowledge described below.
- pallets were usually connected directly to chain bolts on the conveyor chains, which may have been extended.
- conveyor chains with a relatively large pitch were used so that the length of the pallets essentially corresponded to the pitch of the conveyor chains.
- a single pallet spanned the length of several chain links, so that between coupling the pallet to a front chain pin and coupling the pallet to a rear chain pin, one or more chain pins remained that were not connected to the pallet.
- this mechanism is provided in the area of the connection of the pallets to one or more of the chain bolts with which the pallets are to be coupled.

- Embodiments of the assembly method described herein enable a structurally and functionally specially configured conveyor chain to be assembled in a simple manner or to be able to easily disassemble or replace components contained therein.
- the construction according to the invention increases the security against breakage of the conveyor chain by forming parallel chain structures.
- the pallets are not connected directly to the chain bolts of the conveyor chain. Instead, special connection elements are provided to which the pallets can be attached. These connecting elements form a kind of additional chain running parallel to the respective conveyor chain, the connecting elements being many times longer than the chain links of the conveyor chain, i.e. the additional kete formed from the connecting elements has a greater pitch than the chain formed from the chain links. In other words, a connecting element overlaps several chain links.
- the connecting elements are coupled to some of the chain pins of the conveyor chain, which also couple the chain links. Since the connecting elements are longer than the chain links of the conveyor chains, the opposite ends of the connecting elements are each coupled to every second, every third or, more generally, every nth (n> 2) chain pin, that is to say there is at least between two chain pins coupled to a connecting element a ketene bolt that is not coupled to the connecting element.
- connection elements in connection with the two-part design of the chain pins described above are structurally suitable in order to be able to compensate for the differences in length that occur when the conveyor chains are deflected between the shorter chain links of the conveyor chains and the longer connection elements compared to them.
- the conveyor chain can also be deflected around deflection sprockets of small diameter without polygon effects being able to cause undesired effects.
- Pallet belt can be easily assembled, disassembled or exchanged.
- the connecting elements and two-part chain pins can be designed such that the connecting element can be pivoted by removing a second chain pin part and can be decoupled from the first chain pin part in the tangential direction. This allows you to do without extensive
- Disassembly work adjacent fasteners with their opposite Ends are coupled to a common two-part chain pin, can be solved individually from the respective two-part chain pin.
- connection elements or pallets attached to them are to be replaced, for example because of wear, not all connection elements need to be detached from the chain formed by the chain links. Instead, for example, individual connection elements can be loosened and replaced.
- the method according to the invention can be used to create a conveyor chain for a pallet belt of a moving walk, which has a plurality of elongated chain links which are arranged one behind the other in an extension direction of the conveyor chain with a chain pitch, two in each case in the
- the direction of extension of adjacent chain links in a joint region can be subjected to tensile loads with one another by means of a chain pin and are coupled to one another transversely to the direction of extension about a central longitudinal axis of the chain pin.

- Chain links coupled in such a way that:
- the connecting elements are arranged one behind the other parallel to the direction of extension of the conveyor chain
