Definitions
- Feeding device for feeding articles to a container processing machine and container processing machine
- the invention relates to a length-adjustable feed device for feeding articles to a treatment unit of a container treatment machine and to a container treatment machine with such a feed device.
- feeding devices for feeding articles to corresponding treatment units of container processing machines are well known from the prior art.
- feeding devices for feeding cap-like container closures or closure caps to a closing unit of a closing machine are known, which are used, for example, in container treatment systems, in particular in beverage bottling systems.
- Feeding devices which exist in a wide variety of designs, generally include a transport or conveying channel which receives the articles during transport or during the conveying process and along which the articles move.
- the feed devices thus form a conveyor or guide route for the articles.
- the feed devices are usually connected to the treatment unit to which they feed the articles in such a way that the articles can be transferred from the transport or conveyor channel or the conveyor or guide route to the treatment unit.
- containers of different sizes or different formats are usually treated in the treatment units of container treatment machines, it is often necessary, for example, to adjust the height of the corresponding treatment units or container treatment machines, which is why the feed devices connected to them are usually designed to be variable in height and/or length, so that a height adjustment is possible
- the container treatment machine also requires an adapted length adjustment of the feed devices.
- various designs of devices for feeding container closures to closing machines are known from the prior art, the length of which can be changed.
- WO 2011/004102 A1 describes a device for feeding closure caps, in which two tracks of a guide channel run next to one another over at least a predetermined section and can be displaced relative to one another in the longitudinal direction to adjust the length of the device.
- One of the tracks is designed as a threading track from which the container closures are redirected on their conveying path into the adjacent feed track.
- DE 10 2019 127 451 A1 discloses a telescopic device for guiding closure caps, in which two guide rails are provided which are mounted one inside the other and are arranged such that they can be pushed into one another or pulled out.
- WO 2018/041428 A1 also shows a segmented, telescopically adjustable cap channel, which is made up of a large number of segments, each of which can be displaced relative to the adjacent segments, so that a length of the cap channel can be adjusted over a relatively large length range .
- the nested guide rails or segments can lead to disruptive edges or transitions, which can lead to the container closures tilting or jamming.
- the object of the invention is to provide a length-adjustable feeding device for feeding articles to a treatment unit of a container processing machine, which, with a structurally simple design, allows the articles to be fed in a particularly trouble-free and hindrance-free manner.
- the present invention provides a length-adjustable feeding device for feeding articles to a processing unit of a container processing machine.
- the feed device comprises at least a first guide part and at least a second guide part, wherein the guide parts each extend in a longitudinal direction and are arranged in alignment one behind the other in their longitudinal direction along a longitudinal axis of the feed device and each form a portion of a guide path for the articles.
- the feeding device is characterized by a connecting device which is arranged between the guide parts and is displaceable relative to the guide parts in at least one displacement direction running transversely to the longitudinal axis.
- the connecting device is designed in such a way that by moving the connecting device in the direction of displacement, a length of the feed device extending in the direction of the longitudinal axis can be variably adjusted over a predetermined length variation range.
- the two guide parts together with the connecting device displaceably arranged between the two guide parts thus form the guide path for the articles.
- the guide route can in particular be designed as a continuous, preferably gap-free and in particular barrier-free or chicane-free guide route.
- the guide path is free of disruptive edges, disruptive gaps or gaps, or joints or gaps.
- the connecting device interacts with the guide parts arranged in alignment one behind the other in such a way that the length of the feed device along the longitudinal axis can be adjusted by moving the connecting device transversely to the longitudinal axis.
- the length of the feed device is infinitely variable within the length variation range.
- the setting or adjustment of the length of the feed device can include both shortening, that is, setting a shorter length starting from a length that is relatively longer, as well as lengthening, that is, setting a longer length starting from a length that is shorter relative thereto .
- the displacement of the connecting device in the displacement direction transverse to the longitudinal axis can include a forward movement of the connecting device and an opposite backward movement, with which the length settings of the feed device can be made.
- the forward movement of the connecting device can also be understood as a pushing or pushing of the connecting device between the guide parts, whereby, for example, the length of the feed device is increased.
- the backward movement of the connecting device can also be understood as a pushing back or retracting of the connecting device, whereby, for example, the length of the feed device is reduced.
- a “guide part” can also be viewed as a component or component of the feed device and is to be understood in particular as a section of the feed device or as a feed part or feed section.
- Each “guide part” forms or defines a guide route section of the guide route.
- the guide route as such is in particular a straight, linear guide route which preferably extends over its entire length without bends or curves.
- the guide path thus describes an ideal line along which the articles move, with the articles moving forward along this ideal line on their path of movement through the entire guide path, without having to carry out a movement that deviates from this ideal line.
- the articles which can also be referred to here as conveyed items, can be containers, preforms or blanks or preforms or container closures, in particular cap-like container closures, such as screw caps or crown caps.
- articles can also be sealing elements or seals, labels or labels, boxes or other cardboard or packaging materials or the like.
- each guide part has a guide defined by corresponding boundary surfaces (sections) or boundary walls or sections. or have transport space.
- the boundary surfaces (sections) or boundary walls form sliding and/or guiding surfaces for the articles.
- the articles transported by the feed device, in particular fed to the treatment unit of the container treatment machine are therefore preferably not exposed to any change in direction on their path of movement through the guide path and always move in the same feed direction during their feed. A deflection or redirection of the articles on their path of movement through the guide path is therefore not necessary and is effectively avoided, which ensures a uniform, trouble-free and safe supply of the articles to the treatment unit of the container treatment machine.
- the present feeding device is advantageously of extremely simple construction and comprises only a small number of individual parts or components, so that the feeding device is particularly cost-effective and resource-saving both in production and in maintenance.
- Each guide part is preferably designed as a feed channel or guide channel.
- the guide parts can also be understood as channel-shaped or channel-shaped guide parts. This has the advantage that the articles are guided in a particularly safe manner.
- a feed trough or a feed channel has a trough or channel space delimited by corresponding boundary surfaces or walls, in which the articles move as they pass through the feed device.
- each guide part is designed as a feed trough or guide channel
- the guide or transport space is designed as a trough or trough space or as a channel or channel space.
- the feed channel or the feed channel can therefore also be understood as a profile-like guide part, the cross-sectional shape of which is similar to the cross-section of an open profile or a hollow profile.
- the boundary surfaces or walls of the feed can be formed by a continuous, in particular continuous, boundary surface or wall or by several boundary surface sections or wall sections arranged at a distance from one another.
- the cross-sectional shape of the guide parts is adapted to the geometry of the articles to be transported, namely to the geometry of the articles to be supplied to the treatment unit.
- the adaptation to the geometry is such that the articles - which can be cap-like container closures, for example - rest against the boundary surfaces or walls on four sides, namely on the top and bottom and on the side with two opposite sides, and are guided in a sliding manner. In this way, particularly safe and reliable guidance of the articles is ensured, while at the same time ensuring that the articles remain in their desired, predetermined orientation during feeding to the treatment unit and are also transported in this direction without hindering each other.
- the guide parts connected by means of the connecting device together with the connecting device form a flat, in particular obstacle-free and/or transition-free and/or interfering edge-free guide path for the articles.
- a flat guide path is to be understood as meaning that flat sliding and/or guide surfaces for the articles are formed continuously along the guide path.
- the guide path in particular all sliding and/or guide surfaces, are designed without disruptive transitions between the guide parts and the connecting device, in particular while avoiding gaps and joints and/or abutting edges.
- the sliding and/or guide surfaces of the two guide parts connected via the connecting device are flush with one another, so that unhindered transport of the articles is guaranteed.
- the guide parts preferably have connecting ends that face one another and are at least partially spaced apart from one another.
- the at least one connecting device forms a corresponding intermediate piece and cooperates with the connecting ends of the guide parts.
- the connecting device cooperates precisely with the connecting ends of the guide parts, but of course while maintaining the displaceability of the connecting device relative to the guide parts.

- the connecting device can be seen as a variable or variably adjustable spacer or as a variable or variably adjustable spacer.
- the at least one connecting device comprises at least one connecting element, which is particularly preferably formed by at least one slide or a slide arrangement.
- the slide or the slide arrangement can be variably inserted between the guide parts by moving in the sliding direction, with variably selected insertion depths or immersion depths. By inserting the slide or the slide arrangement at different immersion depths, the length of the feed device is advantageously adjusted.
- the connecting element has a cross section in the form of an isosceles triangle or isosceles trapezoid in a cutting plane running parallel to the longitudinal axis and to the direction of displacement. A respective height of the triangle or trapezoid extends in the direction of displacement.
- the connecting element is approximately formed by a body which essentially has the shape of a straight triangular prism or essentially the shape of a straight quadrangular prism.
- the connecting element can assume a variety of different insertion positions or intermediate positions, starting from a minimum position, which can also be understood as a basic position, up to a maximum position, which can also be understood as an end position, with the change in the insertion position causes a change in the length of the feed device.
- each guide part has at least one sliding surface section and the connecting element has a connecting surface arranged between the sliding surface sections of the guide parts.
- the connecting surface of the connecting element cooperates with the sliding surface sections to form a flat and continuous sliding surface of the guide path.

- the connecting elements of the connecting device have a triangular or trapezoidal cross-sectional shape and have two leg surfaces that run obliquely to the longitudinal axis. The leg surfaces of each connecting element slide against the respective inclined surfaces of the strips or side walls.
- the design of the inclined surfaces and leg surfaces are coordinated and adapted to one another with regard to their shape, angles and the like so that the inclined surfaces and leg surfaces are in mutual contact and form corresponding or complementary surfaces, which preferably adhere to one another over the entire displacement distance can slide.
- the first pair of connecting elements is displaceable in a first displacement direction and the second pair of connecting elements is displaceable in a second displacement direction.
- the first and second displacement directions run perpendicular to one another and perpendicular to the longitudinal axis of the feed device.
- At least one drive for displacing the connecting device is also provided in the feed device, wherein the drive can be designed to drive the forward movement of the displacement in the displacement direction and / or the opposite backward movement.
- the connecting device can be displaced in a driven manner, in particular can be pressed in between the guide parts.
- the drive is preferably formed by a pneumatic cylinder, whereby the connecting device can be pressed pneumatically between the guide parts.
- the connecting device can also be referred to as an actively adjustable connecting device or an actively actuable or displaceable connecting device.
- At least one spring element is provided for biasing the connecting device in the displacement direction, namely that the connecting device is spring-loaded and therefore passively displaceable.

- each of the guide parts 3, 4 is designed in the form of a guide channel, such that the guide path for the articles 2 is limited on four sides and thereby provides a channel or channel space limited on four sides through which the articles 2 move forward.
- each guide part 3, 4 has two pairs of opposing, parallel strips 6.1 - 6.4; 7.1 - 7.4, with the strips 6.1 - 6.4; 7.1 - 7.4 are each held by a frame-like holding element 16.

- each connecting element 5.1 - 5.4 with its leg surfaces 10, 10' running obliquely to the longitudinal axis LA, lies slidably against the respective inclined surfaces 12, 12' of the strips 6.1 - 6.4; 7.1 - 7.4, so that each connecting element 5.1 - 5.4 is on the inclined surfaces of the strips 6.1 - 6.4; 7.1 - 7.4 is moved slidably relative to the guide parts 3, 4.
- Figures 3a and 3b show, in an only roughly schematic and highly simplified and isolated representation, an inside view of two strips 6.1, 7.1 of the first and second guide parts 3, 4, which adjoin one another via the connecting element 5.1 in the direction of the longitudinal axis LA, which have a lateral Form a boundary of the guide route.
- the connecting element 5.1 which in the example shown has a cross section in the form of an isosceles triangle and with its leg surfaces 10, 10 'slidingly rests against the inclined surfaces 12, 12' of the strips 6.1, 7.1, can be in the displacement direction SR1 / which runs perpendicular to the longitudinal axis LA.
- SR1 ' can be moved or moved slidably between the bars 6.1, 7.1.
- the sliding displacement of the connecting element 5.1 is possible over a predetermined displacement distance running in the displacement direction SR1 / SR1 ', starting from a basic position or minimum position shown in Figure 3a up to an end position or maximum position shown in Figure 3b.
- the connecting element 5.1 can be moved in particular continuously and variably over the displacement path and can thereby assume a large number of continuously and variably selectable intermediate positions between the basic position and the end position.
- the displacement of the connecting element 5.1 in the displacement direction SR1/SR1 ' can be differentiated into a forward movement VB oriented in the displacement direction SR1, starting from the basic position towards the end position and in one in the displacement direction SR1' and thus counter to the forward movement VB oriented backward movement RB starting from the end position towards the basic position.

- the connecting element 5.1 has on its side or surface facing the channel or channel space a connecting surface 5a, which in turn forms an essentially integral part of the sliding surface 11 or is to be viewed as part of the sliding surface 11 and together with the sliding surface sections 11a, 11 b of the strips 6.1, 7.1 forms the sliding surface 11.
- the strips 6.1, 7.1 and the connecting element 5.1 are configured and aligned with one another in such a way that the sliding surface 11 is designed as a flat and in particular essentially continuous surface. In particular, they close Sliding surface sections 11a, 11b of the strips 6.1, 7.1 and the connecting surface 5a of the connecting element 5.1, while avoiding joint gaps, butt joints, edges, transitions or the like, adhere to one another in such a way that a flat, in particular obstacle and/or transition-free sliding surface 11 is formed.
- the portion of the sliding surface 11 provided via the connecting surface 5a is designed in the form of a triangular surface.
- the portion of the sliding surface 11 provided via the connecting surface 5a is designed in the form of a trapezoidal surface. The proportion of the sliding surface 11 provided via the connecting surface 5a is therefore greater in the end position of the connecting element 5.1 than the proportion in the basic position of the connecting element 5.1.
- a feed device 1 designed, for example, in the form of a cap feeder is shown in a roughly schematically sketched representation in a front view, the cap feeder 1 being shown in the empty state in Figure 4a and in the operating state in Figure 4b an article 2 designed as a closure cover or closure cap (shown in dashed lines in Figure 4b) is located in the channel space of the guide path.

- the strips 6.1 - 6.4; 7.1 - 7.4 and connecting elements 5.1 - 5.4 work together in particular in the manner described with reference to Figures 3a, 3b and are displaced in their respective displacement directions SR1 / SR1 ', SR2 / SR2' to adjust the length of the feed device 1.
- the strips 6.1, 7.1 which are aligned with one another, provide the sliding surface 11 on their side facing the channel space, along which the closure caps 2 slide along with their respective undersides.
- the aligned strips 6.2 and 7.2, the aligned strips 6.3 and 7.3 and the aligned strips 6.4 and 7.4 each provide a first, second and third guide surface 13, 14, 15 on their side facing the channel space, via which the closure caps 2 are guided laterally and on the top, in particular guided in a sliding manner.
- the guide surfaces 13, 14, 15 are also flat, in particular obstacle-free and/or transition-free guide surfaces 13 over the entire length of the guide route , 14, 15 trained.
- the first and third connecting elements 5.1, 5.3 and the second and fourth connecting elements 5.2, 5.4 are arranged in pairs and each form a pair of sliders, the sliders of a respective pair can be operated together.
- the pair of slides 5.1 and 5.3 is displaceable in the displacement direction SR1/SR1' and the pair of slides 5.2 and 5.4 is displaceable in the displacement direction SR2/SR2', the displacement directions SR1/SR1', SR2/SR2' being perpendicular to one another.
- a drive is provided for the actuation of the connecting elements 5.1 - 5.4, which is designed, for example, as a pneumatic drive, for example in the form of a pneumatic cylinder.
- the drive is preferably configured in such a way that it drives the connecting elements 5.1 - 5.4 in the respective displacement direction SR1, SR2 that defines the forward movement VB (see Figure 3a), whereby the connecting elements 5.1 - 5.4 are driven and thus actively between the respective strips 6.1 - 6.4; 7.1 - 7.4 of the guide parts 3, 4 are pushed or pressed between the guide parts 3, 4 in order to force them apart.
- the backward movement RB of the connecting elements 5.1 - 5.4 can take place with or without the effect of the drive.
- the backward movement RB of the connecting elements 5.1 - 5.4 can be triggered and carried out solely by adjusting the height of the closing machine.
- the connecting elements 5.1 - 5.4 can, for example, also be spring-loaded, for which purpose a respective spring element can be provided, via which the connecting elements 5.1 - 5.4 are biased in the displacement direction SR1, SR2.
- the connecting elements 5.1 - 5.4 are forced between the guide parts 3, 4 following the spring tension or spring force when the closing machine is adjusted in height.
- FIG. 5 shows a further embodiment of the feed device 1, in which, in contrast to the variant of Figure 1, each guide piece 3, 4 is designed in the form of a hollow profile rail.
- the hollow profile rail of the guide piece 3 has four side walls 8.1 - 8.4 that adjoin one another at right angles.
- the hollow profile rail of the guide piece 4 includes four side walls 9.1 - 9.4 that adjoin one another at right angles.
- the side walls 8.1 - 8.4, 9.1 - 9.4 of the hollow profile rails of the guide pieces 3, 4 work together with the connecting elements 5.1 - 5.4 to increase the length of the feed device 1 by moving the connecting elements 5.1 - 5.4 to set in the displacement direction SR1/SR1 ', SR2/SR2'.
