Description

CONNECTING ELEMENT FOR MACHINE PROTECTION OF A TANK TREATMENT MACHINE

The invention relates to a connection element according to the preamble of claim 1, to a machine panel or a machine protection according to the preamble of claim 12 and to a container treatment machine with such a machine protection according to the preamble of claim 17. For reasons of occupational safety u.a. also in container handling machines of rotating design, i. in container handling machines having a perimetrically driven container transport element, for example in the form of a rotor revolving around a vertical machine axis, a machine shroud, i. Machine protection is essential, which surrounds the container transport element at least on a part of its orbit and thus defines a protected space in which the container transport element is housed. The machine protection generally consists essentially of at least one wall element, which is made of a transparent plastic material and indeed, for example, in one piece with a plurality of polygonal kinking sites adjoining wall sections.

By a modular design, as it increasingly comes into play in modern container treatment machines, it is possible to perform a variety of treatment processes on containers, for example bottles, using a basic unit comprising the circulating container transport element, by using appropriate treatment modules or aggregates. These treatment modules, which are designed for the respective treatment and are, for example, labeling and / or printing modules, camera modules, alignment modules for aligning the containers, etc., are provided according to the respective treatment method in a different number and / or shape and / or position on the basic unit, and preferably by releasably docking to a machine frame of the base unit. For each treatment module, a breach or opening in the machine protection (hereinafter machine protection opening) is required in order for the relevant module, with its module section directly interacting with the containers during the treatment, to reach into the protected area of the machine protection from the outside. Since previously the machine protection openings for each treatment module adapted to this with high accuracy and therefore must be made individually to meet the requirements for occupational safety, resulting in an almost unmanageable variety of very different designs for machine protection, so cost-effective mass production is not possible , Rather, the respective machine protection in order-related individual production and the container treatment machine has hitherto had to be manufactured individually. Particularly complicated here is the machine protection openings adapted in their dimensions adapted to the respective treatment module with such accuracy that the requirements for work safety are met, which represents a significant cost factor for the production of the respective machine protection.

The invention has for its object to provide a connection element for a machine paneling or for a machine protection, with the (connecting element), the aforementioned disadvantages are avoided and this makes it possible in particular to use while maintaining optimal occupational safety standard versions for machine protection, the then possibly provided in different, adapted to the size of the respective container handling machines standard sizes. To solve this problem, a connection element according to the patent claim 1 is formed. A machine protection is the subject of claim 12. A container treatment machine is the subject of claim 17.

The machine protection openings required for treatment modules or assemblies are produced by cutting with a suitable tool, for example with a jigsaw. Preferably, a connecting element is then fastened with its holder on each vertical cutting edge or on each lateral, vertical opening edge. The latter is preferably designed so that it covers the relevant opening edge, preferably is pushed onto this. Is preferred In this case, the respective opening edge completely covered by the holder, so that no special accuracy is required when creating the respective machine protection opening. Characterized in that the wall element of the connecting element is pivotally mounted on at least one hinge on the holder, namely about an axis which is parallel or substantially parallel to the respective opening edge after mounting of the connection element, it is possible to orient the wall element in Adjust the machine protection in the required manner. By changing the position of the holder relative to the machine protection is at least within certain limits, an adjustment of the connecting element in an axial direction perpendicular to the pivot axis of the at least one joint is possible. Furthermore, means for positioning the wall element and / or for fixing the adjustment of the wall element are preferably provided. In a preferred embodiment, these fixing means are formed by a rod-shaped or tab-shaped connecting element, for example, which connects the wall element of the connecting element directly or indirectly to the machine guard, for example to the wall element of a further connecting element. In the latter case, this connecting element then also determines the distance between the two connecting elements after assembly in the horizontal direction, ie in an axial direction perpendicular to the pivot axis of their joints. Furthermore, there is the possibility that the wall element of the connection element bears resiliently against the treatment module or its protective covering or machine protection, the corresponding spring means acting directly or indirectly on the wall element then being at least part of the means for positioning the wall element, for example. In one embodiment, the spring means act between the holder and the wall element.

As a rule, a connection element is provided at each vertical opening edge of each opening provided in the machine protection. The assembly can for example be made so that the connecting elements mounted individually with their holders individually to the respective opening edge and then to fix the Orientation of their wall elements via the connecting element rotatably connected to each other. However, the mounting can also take place, for example, such that the connection unit formed by the two connection elements and the connection element is preassembled and only then connected to the machine protection.

A "connection element" is in the context of the invention, an element which bridges an existing transition between the machine protection and a treatment module, but at least as far covers or concludes that the protected space is blocked at this transition, at least during normal operation of the container handling machine and preferably as "Adapter" allows easy adjustment of a machine protection to different type, size, number and / or position of treatment modules.

"Container" are in the context of the invention in particular cans, bottles, but also tubes, Pourches, each made of metal, glass and / or plastic, but also other packaging, which are suitable for filling gaseous, liquid, viscous or even solid products ,

The expression "essentially" or "approximately" in the sense of the invention means deviations from the exact value by +/- 10%, preferably by +/- 5% and / or deviations in the form of changes that are insignificant for the function.

In FIGS. 1-5, 1 is a container treatment machine, for example a machine for applying equipment elements to containers, in the illustrated embodiment for applying labels to containers 2. The containers 2, for example in the form of bottles, are fed to the container treatment machine 1 via a container external feed 3 supplies (arrow A). The treated, ie provided with the equipment features or labels container 2 are conveyed away from the container treatment machine 1 via an outer conveyor 4 (arrow B). The container treatment machine 1 includes, inter alia, a rotor 5 which is rotatably mounted about a vertical machine axis (arrow C) on a machine frame 6 and forms at its periphery a plurality of container positions 7, to which the container 2 fed via the feed dog 3 in each case individually be transferred from a transport star 8 formed container inlet. With the rotor 5 driven peripherally around the vertical machine axis, the containers 2 are moved past the treatment module 9 designed as a labeling unit. The treated, ie provided with the labels container 2 are removed from the rotor 5 at a container starter forming transport star 10 and forwarded to the feed dog 4.

For reasons of accident protection, the rotor 5 is on the angular range of its rotational movement between the container inlet formed by the transport star 8 and the container starter 10 formed by the container spout 10, ie outside of the two transport stars 8 and 10 having machine table 11 surrounded by a machine panel or a machine protection 12 which extends along the circular machine frame 6 there or around the vertical machine axis and consists, for example, of a multiplicity of polygon-like adjoining wall elements 13, each with its surface sides parallel to the machine axis of the rotor 5, ie in vertical planes. The machine guard 12 encloses a protected area or space 12.1 and is preferably a prefabricated unit, which is provided in several standard sizes or types depending on the diameter of the respective container treatment machine 1 and the rotor 5. In the region of the treatment module 9, which is preferably docked to the outside of the machine frame 6 as a replaceable unit, the machine protection 12 is provided with a machine protection opening 14, through which the docked treatment module 9 with its cooperating with the containers 2 part of the outside of the machine protection 12th in the protected room 12.1 extends. In order to bridge or cover the transition between the treatment modules 9 and their protective coverings, which are schematically indicated in FIG. 1 with 9.1, and the machine protection 12, the machine protection opening 14 at each vertical opening edge 14.1 is in each case an attachment element 15 forming an additional protective covering provided, which extends over the entire height of the machine opening 14 and projects at least with a wall portion 16.1 on the outer surface of the machine guard 12 such that this wall portion each overlaps a protective covering 9.1 of the treatment module 9. In this case, the respective protective covering 9.1 is preferably adjustable relative to the wall section 16.1 (FIG. 3 - double arrow D), namely while maintaining the overlap between the wall section 16.1 and the protective covering 9.1.

In detail, in the embodiment shown, each connection element 15 consists of a wall element 16 with two rectangular wall sections 16.1 and 16.2 enclosing one another at an angle. On the wall element 16 or on the wall sections 16.1 and 16.2, which can also be made in one piece with each other, a retaining bracket 17 is fixed to the top and bottom, consisting essentially of two an angle with each other, i. in the illustrated embodiment, right angles to each other arranged legs

17.1 and 17.2. On the leg 17.1 of the upper and lower retaining bracket 17 of the wall portion 16.1 is attached to its upper and lower edges. On the leg 17.2 of the upper and lower retaining bracket 17 is the wall portion

16.2 attached in the area of its upper and lower edges. The wall element 16 or the wall sections 16.1 and 16.2 are preferably also made of a transparent plastic.

The brackets 17 are each connected via a hinge 18 with a strip-like holder 19, which is part of the connecting element 15 and extends in the illustrated embodiment over the entire vertical height of the machine protection opening 14. The holder 19 is provided with a longitudinal slot 20 so that it can be pushed onto the respective vertical opening edge 14.1 and then finally fixed there in a suitable manner. At each vertical opening edge 14.1 is a connection element 15, provided with the wall element 16, with the associated brackets 17 and with the deferred to the opening edge holder 19, in such a way that the wall portion 16.2 within the protected space 12.1 and the wall portion 16.1 the protected space 12.1 protrudes through the machine protection opening 14 to the outside. The joints 18 are also located in the protected space 12.1 and are arranged in the illustrated embodiment between the two ends of the respective leg 17.1 and between the longitudinal sides of the wall portion 16.1. The longitudinal sides of the wall sections 16.1 and 16.2 are parallel to the common hinge axis of the joints 8.

In order to stabilize the position of the retaining bracket 7 and thus of the connecting elements 16 at the two opening edges 14.1, a bow-shaped connecting element 21 is provided, which is also arranged in the illustrated embodiment within the protected space 12.1 and the upper headband 17 of the two connecting elements 15 to the free ends of their legs 17.2 with each other rotatably connects. For this purpose, both the free end of the leg 17.1, and the free end of the leg 17.2 of each retaining bracket 17 widened as a fastening tab 17.1.1 or 17.2.1 executed with two mounting holes 22, which correspond to mounting holes at the ends of the connecting element 21. By fastening openings 22 of the leg 17.2 by cross-fasteners 23, the upper bracket 17 are rotatably connected via the connecting element 21. The connecting element 21 consists in the simplest case of a flat material and is formed with several angles adjoining sections so that it follows the course of the machine protection 12 in the mounted state and in any case outside the trajectory of the rotor 5 and the local container positions 7 and Container 2 is located.

The two connection elements 15 and the connecting element 21 form a connection unit 24, with which the transition between the machine protection 12 and the treatment module 9 at the respective machine protection opening 14 in can be covered or protected in a simplified manner, regardless of size, shape and position of the machine protection opening 14th

While the headband 17 and the connecting element 21 as well as the elements of the joints 18 are preferably made of a metallic material, such as corrosion-resistant steel, the strip-like holder 19 preferably made of an elastic material, for example, a sufficiently strong, but elastic plastic, so the respective holder 19 after being pushed onto an opening edge 14.1, the machine guard 12 is held at its inner and outer clamping by clamping at least until after the alignment of the connection elements 15 or the connection unit 24, the final fixation of the holder 19 takes place on the machine protection 12. The connecting element 21 is provided as a standardized component in different lengths adapted to the horizontal width of the machine protection openings 14. Regardless of the length of the connecting element 21, the connecting elements 15 can be used in one and the same embodiment for each width of the machine protection opening 14. With the lower brackets 17, the lower attachment of the connecting elements 15 and their wall elements 16 takes place on the machine frame. 6

In a further preferred embodiment of the present invention, the connecting element 21 is used as a normalized component, which is adapted to different diameters of the rotor 5 of the container treatment machine 1. Also, connecting elements 21 may be provided which are each adapted to a combination of a horizontal width of the machine protection opening 14 and to a rotor diameter. FIGS. 6-9 show, as a further embodiment, a container treatment machine 1a which differs from the container treatment machine 1 essentially only in that a machine opening 25 is provided in the machine protection 12a corresponding to the machine protection 12, which for example is provided for two in the direction of rotation C of the rotor 5 consecutive and in turn, on the machine frame 6 docked treatment modules 9 in the vertical direction or in the direction of rotation C of the rotor 5 has a relation to the machine protection opening 14 greater width. At the two outer vertical opening edges 25.1, the machine guard 12a is in turn provided with a connection element 15 in each case, in the same way as described above in connection with the machine protection opening 14. Between the two opening edges 25.1, a further connection element 15a is provided with a holder 26 which is fastened to the upper horizontal opening edge 25.2 of the machine protection opening 25. The holder 26 consists essentially of a C-shaped arm 26.1 with slot 27 which is fixed at one end with a fastening tab 26.2 on the inside of the machine protection 12a immediately above the opening edge 25.2 such that the arm 26.1 with its longitudinal extent perpendicular or protrudes substantially perpendicularly from the inner surface of the machine guard 12a in the protected space 12a.1. The holder 26 further comprises on the underside of the arm 26.1 a bearing piece 29 which is adjustable in the longitudinal direction of the elongated hole 27 and fixed with screws 28. On the bearing piece 29, two wall elements 16 are pivotally mounted with their upper brackets 17 about a vertical axis, ie in the illustrated embodiment about a common axis parallel to the machine axis. The two longer legs 17.1 of the retaining bracket 17 and thus the local wall sections 16.1 include, for example, an angle smaller than 180 °, for example, an angle of 90 ° with each other, which opens to the outside of the machine protection 12a. The two shorter legs 17.2 of the retaining bracket 17 and thus the wall sections 16.2 then correspondingly include an angle smaller than 180 °, for example also an angle of 90 ° or substantially 90 ° with each other, which opens in the direction of the machine axis of the rotor 5 back , With the ends of the legs 17.2 of these brackets 17 each have a connecting element 21 is connected to one end, the other end is connected to the leg 17.2 of a retaining clip 17 in the region of a vertical opening edge 25.1.

By the connection element 15a or by the holder 26 provided on the wall elements 16 not only the machine protection opening 25 is divided into two partial openings, but through the connection element is also a closed transition to the respective module-side machine protection 9.1 in the area between the successive in the direction of rotation of the rotor 5 treatment modules and closed the machine protection opening 25 between the two treatment modules.

The holder 26 of the connecting element 15a is also made of the metallic material, for example stainless steel. The wall elements 16 and retaining clips 17 of the connecting element 15a are preferably identical to the wall elements 16 and retaining clips 17 of the connecting elements 15. The connecting elements 21 each extend over only a portion of the width of the machine protection opening 25 so that both connecting elements 21 are safely outside the movement space of the rotor 5 and the moving together with the rotor 5 functional elements and container 2 are located. FIG. 10 shows, in a representation like FIG. 4, a further embodiment of the invention, a connecting element 15b, which is provided, for example, instead of the connecting elements 15 at the two opening edges 14.1 and 25.1. The connection element 15b differs from the connection element 15 essentially in that spring means are provided which exert on the wall element 16 a pivot or torque (arrow E of FIG. 10) about the axis of the joints 18, in such a way that the wall element 16 with its wall portion 16.1 resiliently abuts against the treatment module 9 and against the module-side protective cover 9.1. In the illustrated embodiment, the spring means of at least one tension spring 30 are formed, which acts between the holder 19 and the wall member 16.1 or the leg 17.1 at least one holder 7. By the resilient means of the wall element 16 or the wall portion 16.1 generated by the spring means against the treatment module 9 remote from the outside of the module-side protective panel 19.1, the required positioning of the wall element 16 is achieved, i. the spring means or the tension spring 30 are part of the means for positioning the wall element 16.

As also indicated in FIG. 10 by the double arrow F, the module-side protective covering 9.1 is adjustable relative to the connection element 15b or to the wall element 16, specifically in an axial direction parallel to the surface sides of the wall Protective cover 9.1. In this adjustment, the overlap between the wall section 16.1 and the module-side machine protection 9.1 is maintained, and in particular by the fact that the module-side protective cover 9.1 is provided at its machine protection 12 adjacent end with a stop or projection 9.1.1, for example, like a strip is formed extending in the vertical direction and against which the wall portion 16.1 and / or the legs 17.1 rests with its machine protection opening 14 and 25 facing side and a corresponding, of the module-side protective panel 9.1 attacked counter-attack or projection of the wall portion 16 is assigned. This projection is formed for example by the fastening tab 17.1.1 or a strip-like projection of the wall portion 16.1. The connecting element 21 is not required for maintaining the position of the wall element 16. When the machine opening 25 is enlarged in width then, as shown in FIG. 11, the connection element 15c arranged between the two opening edges 25.1 is preferably designed analogously to the connection elements 15b such that the wall elements 16 of the connection element 15c are also resiliently against the respective module side Protective cover abut, by, for example, designed as a compression spring 31 spring means acting between the two wall elements 16 or the headband 17 or between the respective wall elements 16 and the bearing piece 29. By the spring means or compression springs 31, therefore, the connecting element 21 for maintaining the positioning of the wall elements 16 of the end elements 15c is also not required. Instead of the compression springs 31, a leg spring 32 can also be used in each case.

The invention has been described above by means of exemplary embodiments. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.

Thus, it was assumed above that the at least one connecting element 21 within the protected space 12.1 or 12a.1 is arranged. In principle, it is also possible to arrange the connecting element outside this space or the machine protection 12 or 12a, for example in the embodiment of Figures 1-5 in such a way that the two ends of the connecting element 21 with the fastening tabs as 17.1.1 formed free ends of the legs 17.1 are connected.

Furthermore, it was assumed above that on both legs 17.1 and 17.2 of the headband 17 each have a wall sections 16.1 and 16.2 is provided. In principle, it may also be sufficient to design at least the connection elements 15 and 15b such that the wall section 16.1 is provided in each case only on the legs 17.1 of the retaining bracket 17.

Furthermore, it has been assumed above that the wall sections 16.1 and 16.2 are respectively provided at the top and bottom on a mounting bracket 17. In particular, if there are other possibilities for fastening the wall sections 16.1 and 16.2 on the machine frame 6, can be dispensed with lower headband 17. Furthermore, at least the respective wall section 16.1 of the connection elements 15 and / or 15a and / or 15b and / or 15c can be made adjustable in its width perpendicular to the axis of the joints 18, for example by the wall element 16 on the wall section 16.1 having another in Figures 4 and 10 with broken line indicated wall section 16.3 which is relative to the wall portion 16.1 overlapping and guided on this adjustable (double arrow G).
