Definitions
- the invention relates to a transport device for containers with a transport system that is driven to rotate about an axis of rotation and a container guide that is spaced radially outwards from the transport system, the transport system having a large number of container receptacles arranged in the circumferential direction and at least one holding element made of an elastic material being arranged on each of the container receptacles is.
- Such transport devices are basically known from the prior art and are used to transport containers in a container treatment machine between two treatment stations.
- the invention relates in particular to transport stars for container treatment machines in the beverage industry, in which case the containers to be transported are beverage containers, usually cans or bottles made of plastic or glass.
- the individual treatment stations can be labeling and/or filling machines, for example. However, it is preferably a transport device which is used as part of a pack forming device. In such a pack-forming device, the containers are fed in individually and then grouped into packs and fixed to one another.
- DE 20 2004 011 244 U1 teaches a generic transport device in which the containers in the container receptacles bear against two holding elements made of a rubber-elastic material.
- the holding elements prevent the containers from twisting, so that they slide in a rotationally fixed manner along the radially outer container guide and can be fed to the downstream treatment station in a specific position.
- the present invention is based on the object of specifying a transport device which is characterized by greater accuracy and preferably longer maintenance intervals compared to the previously known transport devices.
- the transport system has a radially inner base body and receiving elements formed separately from the base body, the container receptacles being formed on the receiving elements and the receiving elements being arranged radially adjustable on the base body.
- the transport star is not an integral body. Rather, receiving elements formed separately from the base body are now provided, with each of these receiving elements having a container receptacle. Due to the adjustability, it is possible to set a predefined distance between the container guide and the container holder, depending on the container size. This is usually done with the machine at a standstill, with the clearance being fixed for operation. As a result, it is now possible for a constant pressure to act on the containers to be transported and thus also on the holding elements along the transport route specified by the container guide, as a result of which the holding elements are evenly loaded. In addition, it is also possible, after a certain period of operation, to adjust the receiving elements in such a way that the minimum required container pressure can be set again.
- the number of receiving elements depends on the number of container receptacles required, since each receiving element has a container receptacle.
- a preferred embodiment provides that between 8 and 16, preferably between 10 and 14 receiving elements or container receptacles are arranged on a horizontal plane.
- the individual receiving elements or container receptacles are also arranged with a constant angular offset relative to one another in the circumferential direction.
- the adjustable arrangement of the receiving elements on the base body two different configurations in particular have proven to be particularly advantageous.
- the receiving elements each have a protruding adjusting section, which is slidably arranged in guide pockets of the base body.
- the base body has a large number of guide pockets along the circumference, the number of guide pockets being determined by the number of receiving elements to be inserted.
- These receiving pockets are usually designed in the form of an opening or in the form of a groove in the base body, in which case the protruding adjusting section of the base body then engages in these receiving pockets and is arranged within them so that it can be displaced in the radial direction.
- the receiving elements rest in a form-fitting manner in the guide pocket on the lateral edges of the adjusting sections, so that no adjustment can be effected in this regard in the circumferential direction.
- the receiving elements each have a guide pocket in which a protruding control section of the base body is arranged. Accordingly, a large number of adjusting sections are now arranged on the base body, which engage in guide pockets of the receiving elements.
- a development of the invention also provides that the receiving elements can be fixed to the base body. Accordingly, the receiving elements are positioned on the base body with respect to the container guide prior to operation and then fixed in this position. The positions of the receiving elements on the base body are then fixed and cannot be changed during operation of the transport device.
- Fastening means are preferably provided for fixing, these preferably being fastening means which clamp the receiving elements to the base body.
- This can be, for example are screw connections.
- the adjusting sections then preferably have at least one guide groove for guiding the fastening means, the fastening means, e.g. B. the head of a screw, are guided in this groove.
- the groove only extends over a certain section of the thickness of the adjusting section, so that after loosening the fastening means, it is possible to move the corresponding receiving element and, by fixing the fastening means, it can be brought into contact with the receiving element, for example via a head section, and clamp it fixed to the base.
- a particularly preferred embodiment of the invention provides that the container receptacles have a round contact surface, with at least one holding element protruding relative to the contact surface.
- the contact surface is particularly preferably circular at least over a section.
- the radius or the curvature of the container receptacle is based on the size to be transported or the diameter of the container to be transported.
- the individual receiving elements can then be dimensioned according to the size of the container. If the size of the container changes, an exchange is then also possible in a simple manner. However, in addition to replacing individual receiving elements, it can also be expedient to replace the entire transport star, so that correspondingly different transport stars with differently designed receiving elements have to be provided.
- the container holder or the at least circular section of the container holder can have a radius of between 40 and 110 mm, preferably between 50 and 100 mm, particularly preferably between 50 and 70 mm.
- the invention is not limited to a round design of the contact surface of the respective container receptacle.
- the container receptacles can each be formed by a container pocket with a polygonal shape.
- the holding elements preferably protrude in relation to the contact surface, so that when the containers are in contact they can be compressed to a certain extent and a particularly effective anti-twist device can thus be formed.
- the holding elements are, in particular, strip-shaped elements which are then only arranged in certain areas on the contact surface.
- a particularly preferred embodiment provides a total of two or more holding elements on a contact surface.
- the receiving elements for each holding element each have an indentation in the contact surface, with the holding elements then being arranged and fastened in these indentations.
- the depth of the indentation is less than the thickness of the holding element, so that the holding element continues to protrude relative to the contact surface.
- the thickness of the holding elements is preferably between 2 and 5 mm.
- the container guide is only arranged on a peripheral section of the transport star. Accordingly, the container guide does not extend around the entire circumference of the transport system, but only over a certain angular range. This angular range is preferably between 160° and 200°, preferably between 170 and 190°. Accordingly, the peripheral section is between 45 and 55%, preferably between 47 and 53%.
- the transport star wheel forms a transport path only in the area of the container guide, along which the containers are transported.
- This transport path is delimited by an inlet and an outlet, with the container guide correspondingly having an inlet section and an outlet section.
- the distance between the container guide and the transport star wheel is greater than in the sections lying in between. This makes it possible for the container to slide in and/or out of the corresponding container receptacles, including a some offset in the radial direction is required.
- No guideway is then provided in a section opposite the transport path, which is why this section of the transport star wheel serves only as a return section for the individual receiving elements.
- the design of the container guide enables the containers to be transported over an angular range of at least 160° or a circumferential section of at least 45%.
- the container guide is assigned a large number of adjusting devices for setting the distance from the transport star. Accordingly, the distance between the receiving elements and the container guide can be influenced not only by the radial displacement of the receiving elements, but also by the position of the adjusting devices.
- the container guide is usually set first before commissioning. This can be done, for example, with a so-called dummy element, which is arranged in the axis of rotation of the transport stem and has a firmly defined radial extent. This dummy element is then guided along the container guide, which ensures that it has a shape that is as circular as possible. A slightly larger distance then only has to be set in the inlet and/or outlet section.
- the transport star wheel is then used and the position of the individual receiving elements is adjusted, preferably with regard to a constant pressure of the containers in the container receptacles. This can also be done using a dummy container, for example, which is arranged in the corresponding container receptacles.
- the position of the receiving elements can then be adjusted with respect to a pressure defined by the spring element via a spring element between the adjusting section and the fastening pocket, which exerts a force in the radial direction on the adjusting element.
- the elastic material of the holding elements is preferably an elastomer, in particular an elastomer based on natural rubber.
- the material Linatex from the company WEIR Minerals has proven to be particularly effective. This is a rubber-elastic material based on natural rubber, with the proportion of natural rubber corresponding to 95% by weight.
- the container guide is preferably formed from a material, at least on a sliding surface opposite the transport star wheel, which has a lower coefficient of friction than the elastic material of the holding elements. This ensures that the containers slide along the container guide.
- the anti-twist protection is effected exclusively via the holding elements.
- the coefficient of friction of the elastic material of the holding elements is preferably at least 1.5 times greater, particularly preferably 2 times greater than the material of the sliding surface.
- the sliding surface is preferably formed from a plastic.
- the receiving elements are preferably made of a dimensionally stable material.
- a dimensionally stable material refers to a material which is not subject to any appreciable deformation as part of the forces arising during operation of the transport device. Plastics or aluminum are particularly suitable as dimensionally stable materials.
- a further particularly preferred embodiment also provides that two receiving elements are arranged one above the other.
- the transport system consists of two horizontal planes, with the two horizontal planes being of identical or essentially identical design.
- the containers to be transported are then in contact with a receiving element at two different height sections, as a result of which the stability of the container in the system can be significantly increased.
- FIG. 1 shows a container treatment machine with a transport device according to the invention, which includes a transport star wheel,
- FIG 3 shows a detailed view of a receiving element of the transport star.
- FIG. 1 shows a container treatment machine with a first treatment station 1 and a second treatment station 2 as well as a transport device 3 arranged between them, which is set up to transfer containers 4 from the first to the second treatment station 1 , 2 .
- the first treatment station 1 is set up to align the containers 4 in a suitable manner, with the containers 4 then being transferred to the second treatment station 2 in the exact position via the transport device 3 and in which an adhesive is applied to the containers 4 by means of an adhesive application device 5.
- This adhesive can then be used to group the containers 4 together and to fix them in bundles.
- the transport star wheel 6 is shown in more detail in FIG. 2 so that the following description can be better explained in particular by comparing FIG. 1 and FIG. 2 .
- the transport system 6 has a multiplicity of container receptacles 7 arranged in the circumferential direction, with two holding elements 8 each made of a rubber-elastic material based on natural rubber being arranged on the contact surface 9 of these container receptacles 7 .
- the containers 4 are then guided between the container receptacles 7 and a container guide 10, in the course of the distance between the container guide 10 and the container receptacle 7, the container 4 a bit far into the Retaining elements 8 are pressed in, whereby the container 4 is prevented from rotating within the container receptacles 7 .
- the distance between the container receptacles 7 and the container guide 10 is set as constant as possible along the transport angle a, with this being of course the case in an inlet section 11 and in a slightly larger distance between the container receptacles 7 and the container guide 10 can be provided in an outlet section 12, so that the containers 4 can thread into or out of the transport device 3. Nevertheless, a distance that is as constant as possible is expedient between the inlet section 11 and the outlet section 12 so that the holding elements 8 are loaded evenly.
- the container guide 10 In order to ensure this, provision is made on the one hand for the container guide 10 to have a large number of adjusting devices 13, via which the shape of the container guide 10, which only extends over a deflection section defined by the transport angle a along the transport stem 6, can be adjusted in terms of its shape .
- the container receptacles 7 are formed on receptacle elements 14, which are formed separately from a base body 15 of the transport star 6, arranged in an adjustable manner. This is particularly clear from FIG. 3, where adjustability in the radial direction is made possible.
- the individual receiving elements 14 or the container receptacles 7 and the holding elements 8 can be moved closer to or away from the container guide 10 in order to set a desired distance.
- the receiving elements 14 have a protruding adjustment section 16 which is slidably arranged in guide pockets 17 of the base body 15 .
- the receiving elements 14 can be fixed in relation to the base body 15 via fastening means 18, such a fixing being provided for operation.
- the heads of the fasteners tion means 18 out in guide grooves 19 of the adjusting sections 16, wherein the length of these grooves 19 define the maximum adjustment path. Tightening the fastening means 19 then results in a clamping fastening of the receiving elements 14 to the base body 15.
- FIG. 2 also shows that a total of twelve receiving elements 14 with a container receptacle 7 are provided for each horizontal plane, with a total of two horizontal planes being arranged one above the other, so that each container 4 is attached to a receiving element in an upper and a lower section 14 can support.
- the transport system 6 according to FIG. 2 thus has a total of twenty-four receiving elements 14 arranged adjustably on the base body 15 .
- the container guide 10 also has a sliding surface 20 on which the containers 4 are moved in the course of transport.
- This sliding surface 20 is made of a plastic and has a lower coefficient of friction than the material of the holding elements 8. This ensures that the containers 4 slide along the sliding surface 20 on the one hand, with the representative being secured by the holding elements 8.
- the base body 15 and the receiving elements 14 are formed from a dimensionally stable material. This is in particular aluminum or a plastic.
