Definitions
- the invention relates to a transport chain according to the preamble of claim 1 and to a container treatment machine, in particular container cleaning machine according to the preamble of claim 4.
- Container treatment machines in particular in the form of container or bottle cleaning machines are known in various designs.
- the containers to be treated or cleaned are moved in such machines in the manner known to those skilled in the art by means of a transport system through a plurality of treatment zones, which u.a. of immersion or soft and alkaline baths as well as of different spray zones for an internal and external spray of the container with cleaning fluids, also with alkalis and with fresh water are formed.
- the individual treatment zones have different temperatures, so that in any case the transport system, which is usually formed in container cleaning machines by at least two endlessly driven conveyor chains and arranged between them container or bottle baskets, at least once every time to a higher temperature heated and then cooled again.
- the containers may leave the container cleaning machine only with a maximum temperature.
- the containers are cooled on their way to the dispenser, for example by the use of cool fresh water.
- the container or Bottle baskets and also cooled the transport chains which then have to be reheated, which also results in increased heat consumption.
- the object of the invention is to show a transport chain, which is suitable for use in container or bottle treatment machines, but especially in container or bottle washing machines, i. which has sufficiently high load-bearing capacity and wear resistance for this use, but nevertheless has the lowest possible heat capacity in order to reduce the energy losses caused by carry-over of heat energy.
- the lowest possible heat capacity it is common experience that the lowest possible heat capacity is particularly easy to achieve by the lowest possible mass of the components involved or required.
- a transport chain is designed according to claim 1.
- a container treatment machine with at least one transport chain is the subject of patent claim 4.
- the functional elements of the transport chain which are primarily chain links and bolts as well as any guide or rollers, by optimizing not only the smallest possible mass but these functional elements are also designed so that they exploit the properties of the material used in an optimal manner.
- the functional elements are preferably also designed so that liquids from the transport chain run off and drip quickly and without problems, so that a carryover of cleaning or treatment liquids from a treatment zone into subsequent treatment zones is largely avoided. This also contributes to a reduction of energy losses and also avoids the stress of treatment zones by delayed treatment and cleaning fluid.
- Fig. 1 shows a partial length of a transport chain according to the invention for use in a container treatment machine, such as container or
- Fig. 2 is a plan view of the partial length of the transport chain of Figure 1; 3 shows an individual view and a side view of a chain link of a transport chain in a further embodiment of the invention; 4 shows a section along the line I - I of Figure 4;
- FIG. 9 in an individual representation and in longitudinal section a bolt for use in the transport chain according to the invention.
- 1 is a transport chain, of which only a partial length is shown, and which is part of a transport system of a container treatment machine, namely a container or cleaning machine.
- the transport system with which the bottles or the like containers to be cleaned between a container or bottle inlet and a container or bottle outlet of the cleaning machine by a variety of treatment zones with different temperature, including various immersion or alkali baths and different injection zones for indoor and / or ornessabspritzung comprises, in the manner known to those skilled in such two closed loop forming, endlessly driven transport chains 1. Between these container or bottle carrier for receiving a plurality of containers or bottles are provided.
- the transport chain consists in a conventional manner of several pairs of strap-like chain links 2, from these chain links interconnecting bolts 3 with bearing sleeves 4 and a plurality of rollers 5, each formed on each of a bolt 3 and a bearing sleeve 4 chain joint are rotatably mounted on the local bearing sleeve 4 and between two chain links 2, namely for supporting the transport chain 1 on a running surface. 6
- the transport chains 1, each forming a long loop through the entire treatment machine extending closed loop are highly loaded during operation of the treatment machine, in particular by the forces acting on the transport chains 1 tensile forces, but also by a constant temperature change and by the treatment media or -Liquids of the treatment zones (alkalis).
- the functional elements of such transport chains ie for the chain links 2, the bolt 3, the bearing sleeves 4 and rollers 5 highly resilient materials, ie steels with sufficiently high strength, eg steels Class C45 used.
- container cleaning machines is, inter alia, that during operation of a container treatment machine with the respective transport chain 1, there is an energy carryover from treatment zones of higher temperature into treatment zones of low temperature and thus considerable energy losses occur.
- Another problem is in addition to the desired, low dispensing temperature of the container, since in addition to the containers and the transport chain 1 and the container or bottle baskets are cooled, resulting in a subsequent, energy-consuming heating by itself.
- a further problem also exists in the carryover of liquid treatment media from one treatment zone into subsequent treatment zones, for example in the carryover of treatment liquid from dipping or lye baths into subsequent dipping or lye baths or into subsequent treatment zones, etc., resulting in at least a loss of treatment liquid in preceding treatment zones and / or leads to a load or contamination of treatment liquid in subsequent treatment zones.
- the transport chain 1 is basically designed such that it or its functional elements have a reduced mass and thus a reduced heat capacity, while maintaining the at least required fatigue strength.
- Executed transport chains 1 have, for example, a load capacity of at least 150 kN in a first embodiment and a load capacity of at least 250 kN in a second embodiment. To improve the readability of the present application, only the said second embodiment is subsequently treated, it being understood that this procedure has no restrictive effect on the scope of protection of the present application.
- the mass of a transport chain according to the invention is about 5.30 kg to 6.20 kg per pair of links, but preferably only between 4.60 kg and 5.33 kg. This is, as explained in more detail below, achieved in particular by a special shape of the functional elements of the transport chain 1, which is achieved by the fact that the properties of the materials used are optimally used.
- Energy losses also exist in the selection of a suitable material for the functional elements of the transport chain 1, e.g. by selecting a material with increased strength values, whereby the component dimensions and thus its mass and also its heat capacity can be reduced in the desired manner.
- a further improvement in terms of avoiding energy losses can also be achieved by selecting a material which has a lower thermal conductivity, and thus absorbs or releases a smaller amount of heat within a time interval under otherwise identical conditions.
- materials with improved properties in the group of low-alloyed or high-alloyed steels were found for the rollers and links of the transport chain.
- steels from the group of tempered steels since these have a higher strength compared to the prior art, and thus allowed a significant reduction in the component dimensions.
- the mass of the transport chain 1 is reduced in detail by the fact that the chain links 2 produced as flat straps, for example by punching from a flat material with openings 7 for the bolts 3, are provided with a constriction on at least one longitudinal side by a concave curvature about axes parallel to the axes of the openings 7 are formed waisted, as shown in Figure 1 with the sidecut 8.
- the sidecut 8 is located at the angled 2.1 for the attachment of a container carrier opposite upper longitudinal side of each chain link 2.
- the total length L of the chain links 2 at predetermined center distance A of the successive in Transportkettenltician bolt 3 is greatly reduced.
- the total length L of each chain link is about 1, 5 times the center distance A (150% of the axial distance A)
- the total length L of a chain link 2 of the transport chain 1 according to the invention is only about 1, 3-fold to 1 , 46 times (130% to 146% of the center distance A), preferably 1, 36 times the axial distance A (136% of the center distance A).
- Chain link longitudinal direction extending and the underside of the chain link 2 or the respective bend 2.1 enclosing plane is about 30% to 40% of the axial distance A.
- the corresponding width in particular in the central region of the chain link 2 and at the local there Sidecut 8 is greatly reduced and at this point, for example, only about 26 to 33% of the axial distance A, preferably only 31% of the axial distance A, so that a total of a significant reduction of the chain links 2 in length and width and thus a significant reduction in the mass of each Chain link are reached.
- Figures 3 and 4 show a further embodiment of a chain link 2a, which can be used together with a plurality of similar chain links 2a instead of the chain links 2 in the transport chain 1.
- the chain link 2a differs from the chain link 2 essentially in that it is fitted at least at the top at 8 and at the bottom at 9 by a respective concave curvature about axes parallel to the axes of the openings 7, ie between the two, respectively an opening 7 having ends one significantly reduced width B has.
- the chain link 2a is also waisted at the two longitudinal sides at 11 and 12, respectively by a concave curvature about axes perpendicular to the axes of the openings 7, resulting in a significant reduction of the total mass of the respective chain link 2a contributes.
- the chain element 2a has a shape which is essentially characterized by two end pieces or head pieces 12 with an enlarged material cross-section and by a center piece 13 with a reduced material cross-section lying therebetween.
- the width of the head pieces 12 in the axial direction of the openings 7 is substantially greater than the corresponding width of the center piece 13.
- the width of the head pieces 12 is substantially larger radially to the axis of the respective opening 7 than the corresponding width of the center piece 13.
- two recesses or through openings 14 are provided, which also contribute to the reduction of the total mass of the chain link 2a.
- the special shape of the chain link 2 a is optimized so that in no operating state of the transport chain 1 or the container treatment machine, a load which destroys the chain links 2 a, i. despite significantly reduced mass, the fatigue strength of the transport chain 1 of at least 250 kN is reached.
- Container cleaning machines can be produced economically exclusively by punching. Due to the technical restrictions of the stamping method, taking into account the properties and dimensions of the material used according to the prior art only flat, flat chain links can be produced, the outer and / or inner contours are determined by simple geometric elements such as straight lines and circles.
- this limitation is overcome by the use of more modern or hitherto not customary manufacturing methods, such as fineblanking, laser and / or plasma cutting, drop forging or investment casting.
- Chain links are essentially concerned with the embodiment 2a, but apply analogously to both presented embodiments of the chain links 2, 2a.
- each volume element is to be understood as meaning a computationally determined reference stress, this comparative stress being determined by known and recognized methods, for example by the methods according to FIG. Mises or Mohr, can be determined.

- the respective chain link 2a is produced, for example, as a forged part in a die or as a casting, namely of a high-strength material, namely steel, preferably one of the abovementioned alloyed steels.
- each roller 5 of the conveyor chain 1 are designed so that they have the lowest possible mass with sufficiently high strength and stability, ie, each roller 5 is concentric with the axis on at least one of its two end faces the roller or the roller opening 18 enclosing, groove-like recesses 19 provided so that the total volume and thus the total mass of each roller 5 amount to less than 90% of the corresponding parameters of a conventional roller.
- total volume and mass of a roller according to the invention only about 75 - 85%, preferably about 80% of the volume and thus the total mass of a conventional roller, the conventional roller with respect to diameter, width and design of the bearing opening 20 of the roller 5 corresponds, but the recesses 19 does not have.
- roller 5 may be arbitrarily shaped openings 23.
- These breakthroughs 23 may be, for example, a plurality of holes which are introduced at a uniform angular distance in the roller 5, whereby a spoke-like shape may arise, which additional or alternative
- these openings 23 may also be cutouts which surround the roller opening 18 in the shape of a circular ring segment.
- the ring groove-like, the axis of the roller 5 concentrically enclosing recesses 19 are beveled at its inner and outer lateral annular surface 19.1 and 19.2 in such a way that the width of the recesses 19 increases towards the open side, as shown enlarged in FIG.
