Description

The invention relates to a bottle cell carrier for a bottle cleaning machine and a bottle cleaning machine comprising at least one bottle cell carrier according to the independent claims.Prior ArtIt is known that bottles to be cleaned over the housing width of a bottle cleaning machine can be introduced into provided honeycombs, so-called bottle cells. The bottle cells are generally arranged next to one another and, in a welded connection with support strips and side parts, result in the so-called bottle cell carrier. The bottle cell carriers located in the bottle cleaning machine can be pulled through solution baths along a respective roller chain on the outer sides of the bottle cell carriers during operation. In the lateral part of the bottle cell carriers on both sides, for example, two bores can be used for a rigid 2-bolt fastening with locking tooth nuts on the chain.The chain guide in the machine housing, for example chain deflections and associated deflection gears, and the bottle cell carriers themselves, can be subject to conventional manufacturing tolerances. The rigid 2-bolt fastening between chain and bottle cell carrier can lead to forces-for example due to manufacturing tolerances, wear and general condition of the machine-being able to be transmitted from the chain to the bottle cell carriers. These forces may be indefinable. This circumstance can lead to unacceptably high voltages occurring in the bottle cell carriers. During operation of a bottle cleaning machine, each bottle cell carrier may experience continuously changing loads due to the situation. The high stresses in cooperation with the last-mentioned load changes can lead gradually to hair cracks, tears and finally to the breakage of bottle cell carriers.The object is to provide a method for performing a processThe object of the invention is to provide a bottle cell carrier for a bottle cleaning machine and a bottle cleaning machine comprising at least one bottle cell carrier, which can enable the bottle cell carrier to be used as wear-free as possible in a bottle cleaning machine.SolutionThe object is achieved by the bottle cell carrier for a bottle cleaning machine and the bottle cleaning machine comprising at least one bottle cell carrier according to the independent claims. Further embodiments are disclosed in the dependent claims.The bottle cell carrier for a bottle cleaning machine according to the invention is configured to be transported through the bottle cleaning machine by means of roller chains and comprises at least one carrier bar having a plurality of bottle cell receptacles for receiving bottle cells and two side parts connected to the at least one carrier bar, wherein the bottle cell carrier further comprises a mechanical connecting device per side part which is configured to allow a relative movement between the side part and the roller chain after connecting the side part and a roller chain of the bottle cleaning machine by means of the mechanical connecting device.The relative movement between the side part and the roller chain can mean a relative movement at the connection point or connection region of the side part and roller chain. A relative movement to the entire roller chain may not be meant thereby.The mechanical connecting device can give the bottle cell carrier sufficient degrees of freedom and a force transmission from the roller chains to the bottle carrier can be decoupled.In rigid 2-bolt attachments between roller chains and bottle cell carriers known from the prior art, forces can be transmitted from the roller chains to the bottle cell carrier. The forces can result in high stresses in the bottle cell carrier. During operation of a bottle cleaning machine, the bottle cell carrier can experience continuously changing loads due to the situation and the high stresses in cooperation with these load changes can lead to hair cracks, tears and finally to the breakage of the bottle cell carrier during operation.This can be avoided by the bottle cell carrier according to the invention by means of the mechanical connecting device which is designed such that after connecting the side part and the roller chain of the bottle cleaning machine by means of the mechanical connecting device it enables a relative movement between the side part and the roller chain. The high voltages arising in the prior art can be significantly reduced.The mechanical connecting device can comprise, for example, a universal joint or a ball joint. Such joints can allow an angularly movable movement about two axes perpendicular to each other. The course of the axes can be predetermined by bolts which can be used for a connection of side plates of the side part or for a connection to a roller chain plate.The side part may comprise two side plates each having a passage for receiving a first bolt of the mechanical connection device. The side flaps can be arranged at a distance from one another in such a way that the mechanical connecting device can be arranged at least partially between them.The side flaps can be oriented parallel to a longitudinal axis of the bottle cell receptacles. Accordingly, the first bolt can be arranged, for example, perpendicular to the longitudinal axis of the bottle cell receptacles.The mechanical connection device may include a second bolt for connection to a roller chain plate. For example, the roller chain plate can be designed in such a way that the second bolt can be arranged parallel to the longitudinal axis of the bottle cell receptacles.The first bolt and the second bolt may be oriented perpendicular to one another after the side part and the roller chain are connected by means of the mechanical connecting device.The support strip can comprise a plurality of lightweight cut-outs. For example, the lightweight sections can be bounded by webs.It can occur that, due to the mechanical connecting device, which enables a relative movement between the side part and the roller chain, the inherent weight of the bottle cell carrier and its loading with bottles to be cleaned in the central region thereof can lead to a deflection, which can be undesirable. In order to be able to reduce this deflection, the lightweight cut-outs can be provided in order to reduce the intrinsic weight of the bottle cell carrier.For example, at a load of about 92 kilograms and a length of 4.3 meters, the deflection at the center may be about 7.9 millimeters.Webs can be provided which can connect two welding points between the carrier strip and a bottle cell inserted into a bottle cell receptacle.A width of the webs can be formed so as to become narrower from the side parts towards a center of the support strip. Because webs with the same orientation, e.g. transversely or obliquely at a given angle, can become narrower from the outside to the inside in the direction from one side part to the other, i.e. from the two side parts to the center of the support strip, the support strips can be constructed more easily overall than with a constant width of the webs.A width of the webs can be dependent on a width of the support strip. The width of the carrier strip can be different for different types of containers to be accommodated, since, for example, a smaller bottle cell can be provided accordingly for a container with a smaller diameter. A size of the bottle cell receptacle can be made correspondingly smaller.The lightweight cut-outs can comprise triangles.In each case three webs can delimit one of the lightweight cut-outs.Corners of the triangles can be rounded. The rounding can prevent voltage peaks.Starting from the side parts towards the center of the support strip, the lightweight cut-outs can become larger in terms of area from a first area size to a second area size. It can be expected that greater stresses can act on the support strip in one region of the side parts than in other regions of the support strip away therefrom. It may be expedient to obtain more material of the support strip in a region of the side parts and therefore to provide smaller lightweight cut-outs there.At a distance from the side parts, no lightweight cut-outs can be provided. Here too, the aforementioned stresses can play a role, which is why it can be expedient to obtain material of the support strip at the distance from the side parts and therefore to provide no lightweight cut-outs there.A bottle cleaning machine comprising at least one bottle cell carrier as described above or below and roller chains for transporting the bottle cell carriers through the bottle cleaning machine is provided.The bottle cell carrier can have a connection between the side parts and the roller chains of the bottle cleaning machine by means of the mechanical connecting devices, which can enable the relative movement between the side part and the roller chain.Brief description of the FiguresThe appended figures represent, by way of example, aspects and / or exemplary embodiments of the invention for better understanding and for illustrative purposes. It shows: FIG. 1 is an oblique view of a part of a bottle cell carrier; and FIG. 2 is an oblique view of a part of the bottle cell carrier with the mechanical connecting device.Detailed Figure DescriptionFIG. 1 shows an oblique view of a part of a bottle cell carrier 1. the bottle cell carrier 1 comprises a carrier strip 2 with a plurality of bottle cell receptacles 3 for receiving bottle cells 4 and two side parts 5 connected to the carrier strip 2, one of which can be seen in the illustration.The side part 5 comprises two side straps 6 each with a passage 7 for receiving a first bolt of a mechanical connecting device. The mechanical connecting device is designed such that, after connecting the side part 5 and a roller chain of a bottle cleaning machine in which the bottle cell carrier can be used, a relative movement between the side part 5 and the roller chain can be made possible by means of the mechanical connecting device. The side flaps 6 are arranged spaced apart from one another in such a way that the mechanical connecting device can be arranged at least partially between them.The side flaps 6 are oriented parallel to a longitudinal axis of the bottle cell receptacles 3. Accordingly, the first bolt can be arranged perpendicular to the longitudinal axis of the bottle cell receptacles 3.At a distance d from the side parts 5, no lightweight cut-outs are provided. It can be expected that greater stresses can act on the support strip 2 in one region of the side parts 5 than in other regions of the support strip 2 away therefrom. It may be expedient not to provide any lightweight cut-outs at a distance d from the side parts 5.Starting from the side parts 5 towards the center of the support strip 2, provided lightweight cut-outs 8, 9, 10, 11 can become larger in terms of area from a first area size to a second area size. As already mentioned, it can be expected that greater stresses can act on the support strip 2 in the region of the side parts 5 than in other regions of the support strip 2 away therefrom. It can therefore be expedient to obtain more material of the support strip 2 in a region of the side parts 5 and therefore to provide smaller lightweight cut-outs 8, 10 there.The lightweight cut-outs 8, 9, 10, 11 comprise triangles, the corners of which are rounded. The rounding can prevent voltage peaks.In each case three webs 12, 13, 14 can delimit one of the lightweight cut-outs 8, 9, 10, 11.FIG. 2 shows an oblique view of a part of the bottle cell carrier 1 with the mechanical connecting device 18.A roller chain plate 17 is designed in such a way that a second bolt 16 for connecting the roller chain plate 17 and the mechanical connecting device 18 is arranged parallel to the longitudinal axis of the bottle cell receptacles 3.Accordingly, after the side part 5 and the roller chain are connected by means of the mechanical connecting device 18, the first bolt 15 and the second bolt 16 are oriented perpendicular to one another.
