Description

[Technical Field]

[0001] The present invention relates to a device for attaching an article to an object, and in particular to a device for attaching an article to a moving object. [Background technology]

[0002] A device for affixing an article to a moving object, i.e. an object passing through the device, can be used to affix an article such as a drinking straw or a label to an object such as packaging.

[0003] Objects such as packages may be fed from machines such as filling machines at high production rates, and therefore devices for applying articles to objects fed from the machine must be able to accommodate this high production rate.

[0004] One type of device for applying an article to a moving object is known, for example, from US 4,584,046, which discloses a device comprising an arm having an applicator head arranged to reciprocate between a collection position where the applicator head collects the article, and an application position where the applicator head applies the article to the object. However, such a solution can have difficulty in properly positioning the article on the object if the object moves too quickly.

[0005] A solution to this problem is presented in WO2016096380A1, which discloses an apparatus for attaching drinking straws to packaging. The apparatus includes a bracket journaled on two eccentric shafts. Rotation of the shafts allows the applicator head of the bracket to move along a circular path that passes through a retrieval position and an attachment position. The circular path allows the applicator head to move in a direction that has a component of the object's movement direction, so that the applicator head can move with the package for a period of time after attaching the drinking straw, thereby ensuring accurate positioning of the drinking straw. Other related background art can be found in US2017 / 341793A1 and US4584046A. Summary of the Invention

[0006] In view of the above, it is an object of the present invention to provide a device for affixing an item to a moving object.

[0007] It is also an object of the present invention to provide such a device which ensures accurate positioning of articles on moving objects during high speed production.

[0008] In order to achieve at least one of the above objects, as well as other objects that will become apparent from the following description, according to the present invention there is provided a sealing element having the features defined in claim 1. Preferred embodiments of the device become apparent from the dependent claims.

[0009] More specifically, the present invention provides a device for applying an article, such as a drinking straw or label, to a moving object, such as a package. The device includes an applicator member including a base element and an arm element, the arm element being telescopically coupled to the base element such that the arm element is movable between a contracted state and an extended state. The device also includes a biasing member configured to bias the arm element toward its extended state. An actuator shaft is pivotally connected to the base element, the actuator shaft being eccentrically disposed and rotatable about a first rotation axis RA1. A support member is pivotally disposed about a second rotation axis RA2 and slidably supports an intermediate portion of the arm element of the applicator member. A free end of the arm element includes an applicator head, the applicator head being cyclically movable between a collection position, in which the applicator head is configured to collect the article, and an application position, in which the applicator head is configured to apply the article to the object, in response to rotation of the eccentrically disposed actuator shaft about the first rotation axis RA1. The arm element is configured to assume its contracted state while the applicator head moves from the retrieval position to the application position, and is configured to assume its extended state while the applicator head moves from the application position to the retrieval position.

[0010] This provides a device that allows for accurate positioning of articles on moving objects during high speed production.

[0011] The applicator member comprises an arm having a base element and an arm element telescopically coupled thereto, the base element pivotally coupled to a rotatable eccentric shaft, an intermediate portion of the arm element slidably supported by a pivotable support member, such that an applicator head formed by a free end of the arm element is cyclically movable in response to rotation of the actuator shaft between a collection position for collecting an article and an application position for applying an article to a moving object.

[0012] The arm elements are movable between an extended state and a retracted state, and the arms are biased toward the extended state.

[0013] The arm elements are further configured to be retracted during movement of the applicator head from the retrieval position to the application position. Rotation of the actuator shaft cyclically moves the applicator head between the retrieval position and the application position. Retraction of the arm elements during movement of the applicator head from the retrieval position to the application position allows flattening of the curved path followed by the applicator head during this movement, allowing for clear application of the article onto the object.

[0014] The arm elements are also configured to assume their extended state during movement of the applicator head from the application position back to the retrieval position. As a result, the applicator head may be caused to follow a curved path as it is moved toward the retrieval position. The curved path may be configured such that immediately after application of the article, the applicator head is moved in a direction having a component that coincides with the feed direction of the moving object, and by matching the speed at which the applicator head is moved along this component of the feed direction with the feed speed of the object, it may be ensured that the applicator head moves a distance together with the article being applied to the object, thus maintaining engagement with the article and pressing it against the object before being lifted off the article and returned to the retrieval position. This may ensure that the article maintains precise positioning on the object after it has been applied thereto.

[0015] According to one embodiment, the arm elements may be configured to be extended from an extended state to a retracted state and then returned to an extended state while the applicator head moves from the retrieval position to the application position, such that the applicator head moves along a substantially straight path. By configuring the arm elements to be extended from an extended state to a retracted state and then returned to an extended state while the applicator head moves from the retrieval position to the application position, a curved path that the applicator head would otherwise follow can be flattened to the extent that the path is substantially straight, thereby improving the accuracy with which the article can be applied onto the moving object.

[0016] According to another embodiment, the arm element may be provided with a fixedly disposed protrusion configured to engage the support member during movement of the applicator head from the retrieval position to the application position. When the protrusion is engaged with the support member, the arm element may be configured to be forced into its contracted state in response to continued rotation of the eccentrically disposed actuator shaft. The arm element may be slidably supported by the support member, and by disposing the protrusion on the arm element, the protrusion may engage the support member in response to relative movement between the arm element and the support member, thereby preventing further relative movement. When engagement between the protrusion and the support member is established, the arm may be forced into its contracted state by a telescopic coupling between the arm element and the base element. The protrusion provided on the arm element may be disposed on a side of the support member facing the base element of the applicator member.

[0017] According to yet another embodiment, the protrusion may be configured to cooperate with a biasing member.

[0018] According to yet another embodiment, the arm elements may be configured to be maintained in an extended state while the applicator head moves from the application position to the retrieval position, such that the applicator head moves along a curved path. By maintaining the arms in an extended state, the curved path imposed on the applicator head by rotation of the actuator head can be fully utilized.

[0019] According to yet another embodiment, the biasing member may comprise a spring member.

[0020] According to yet another embodiment, the attachment member may comprise an additional base element and an additional arm element telescopically coupled thereto, the additional base element and the additional arm element extending parallel to the base element and the arm element.

[0021] The applicator head may be arranged to dispense and apply an article in the form of a drinking straw.

[0022] The applicator head may be arranged to apply the article to an object in the form of a package.

[0023] The support member may comprise a sliding bearing for supporting an intermediate portion of the arm element.

All references to "a / an / the [element, device, component, means, step, etc.]" should be openly interpreted as referring to at least one instance of said element, device, component, means, step, etc., unless expressly stated otherwise.

[Figure 3] FIG. 3 is a schematic diagram illustrating the operation of the device. [Figure 4] FIG. 4 is a schematic diagram of the device showing the applicator head in the retrieval and application positions, respectively. DETAILED DESCRIPTION OF THE INVENTION

[0027] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown: The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0028] In Figure 1 there is shown a device 1 for applying articles to a moving object, i.e. an object that is moved past the device 1. The object may be moved by, for example, a conveyor.

[0029] The device 1 may be configured to apply an item such as a label or drinking straw to an object such as a package.

[0030] The device 1 comprises an applicator member 2 which in the embodiment shown comprises two arms arranged parallel to one another, it being understood that the applicator member 2 may comprise only one arm or more than two arms.

[0031] Each arm comprises a base element 3 and an arm element 4, the arm element 4 being telescopically coupled to the base element 3 so as to be movable between a contracted state and an extended state. In the figures, the arm element 4 is shown in its extended state.

[0032] The device 1 further comprises a biasing member 5 configured to bias each arm element 4 towards the extended state. In the illustrated embodiment, the biasing member 5 comprises a spring member.

[0033] The attachment member 2 is pivotally coupled to an actuator. The actuator comprises an actuator shaft 6 that is arranged at a distance from the first rotation axis RA1 and is rotatable about the first rotation axis RA1. In this way, the actuator shaft 6 is arranged eccentrically about the first rotation axis RA1.

[0034] An actuator shaft 6 is pivotally connected to the base element 3 of each arm. More specifically, an end 7 of each base element 3 is journalled to the actuator shaft 6 so that the arm can pivot about the actuator shaft 6.

[0035] The device 1 further comprises a support member 8 pivotable about a second axis of rotation RA2 and arranged to slidably support the applicator member 2.

[0036] The second rotation axis RA2 is disposed parallel to the first rotation axis RA1.

[0037] In the embodiment shown, the support member 8 comprises a support structure for each arm. The support member is journalled on a support shaft 9 extending along a second axis of rotation RA2, and therefore the support member 8 is rotatable about the second axis of rotation RA2.

[0038] Each support structure of the support member 8 is configured to slidably support an intermediate portion 10 of each arm element 4 of the applicator member 2 and may comprise a sliding bearing configured to slidably receive the intermediate portion 10.

[0039] The applicator member 2 includes an applicator head 11, which is cyclically movable between a collection position in which the applicator head 11 is configured to collect an article and an application position in which the applicator head 11 is configured to apply an article to an object in response to rotation of an actuator shaft 6 eccentrically positioned about a first rotation axis RA1.

[0040] Each arm element 4 of the applicator member 2 is configured to assume its contracted state while the applicator head 11 moves from the recovery position to the application position, and is configured to assume its extended state while the applicator head 11 moves from the application position to the recovery position.

[0041] Each arm element 4 is provided with a fixedly arranged protrusion 12 configured to engage the support member 8 during movement of the applicator head 11 from the retrieval position to the application position. The protrusion 12 of each arm element 4 is arranged on the side of the associated support structure facing the base element 3 telescopically coupled to the arm element 4.

[0042] Each arm element 4 is configured to be urged into its retracted state in response to continued rotation of the eccentrically disposed actuator shaft 6 after the protrusion 12 is engaged with an associated support structure of the support member 8.

[0043] In the illustrated embodiment, an applicator head 11 is formed by the free end 13 of each arm element 4 and is configured to dispense and apply an article in the form of a drinking straw. It will be understood that the design of the applicator head will depend on the type of article to be dispensed and applied. For example, the free ends of the arm elements may be interconnected to form an applicator head configured to apply a label or other type of form article.

[0044] The articles may be supplied from a supply. The drinking straws may be provided as a web, with each drinking straw wrapped in a protective envelope. In the embodiment shown, such a web may be supplied to drive means 14 in the form of a supply wheel arranged to hold the web. A knife 15 is arranged to separate each wrapped drinking straw from the web. The separated wrapped drinking straws are then advanced one by one to a position associated with a collection position of the applicator head 11 of the applicator member 2.

[0045] The configuration of the device 1 and one of the arms of the applicator member 1 is more clearly shown in FIG. 2, to which reference is now also made.

[0046] The device 1 comprises a rotatable actuator wheel 16 that eccentrically supports the actuator shaft 6 at a distance from the first axis of rotation RA1. The actuator wheel 16 may be rotated by a motor (not shown), such as a servo motor.

[0047] An end 7 of the base element 3 is journalled to the actuator shaft 6 and is therefore pivotable relative to the actuator shaft 6 .

[0048] The base element 3 defines a cavity 17 extending longitudinally of the arm.

[0049] An end 18 of the arm element 4 is slidably received by the cavity 17 such that the arm element 4 is telescopically coupled to the base element 3 and is movable between a contracted state and an extended state.

[0050] The support structure of the support member 8 is rotatable about a second axis of rotation RA2 arranged parallel to the first axis of rotation RA1.

[0051] The support structure comprises a sliding bearing 19 which slidably supports the intermediate portion 10 of the arm element 4 .

[0052] In the illustrated embodiment, a pin 20 extends laterally through the end 18 of the arm element 4. Opposite ends of the pin 20 are received by two oppositely disposed slots 21 provided in the base element 3 and extending longitudinally of the arm. The pin 20 and slots 21 thus define the retracted and extended states of the arm element 4.

[0053] The protrusion 12 is arranged on the arm element 4 on the side of the support structure facing the base element 3. In the embodiment shown, the protrusion 12 is in the form of a washer.

[0054] The arm of the applicator member 2 comprises a biasing member 5 in the form of a spring element configured to bias the arm element 4 towards its extended state. In the embodiment shown, the spring element is arranged between a heel 22 provided on the base portion 3 and a protrusion 12 in the form of a washer.

[0055] The operation of the device will now be described with reference to Figure 3 which illustrates the device 1 in positions A to H.

[0056] Successive rotations of the actuator shaft 6 through positions A to H cause the angle of the applicator member arms to change periodically, and the pivotable support member 8, which slidably supports the intermediate portion 10 of the arm element, helps to accommodate these changes in the arm angle.

[0057] In position A, the arm elements 4 are in an extended state and the applicator head 11 is in a withdrawn position.

[0058] By rotating the actuator shaft 6 counterclockwise as indicated by arrow P1, the device 1 first moves from position A to positions B and C, causing the base element 3 pivotally coupled to the actuator shaft 6 to move in a first lateral direction as indicated by arrow P2, and causing the end 7 of the base element 3 to move in a first transverse direction as indicated by arrow P4.

[0059] Movement of base element 3 in first lateral direction P2 causes protrusion 12 provided on arm element 4 telescopically coupled to base element 3 to engage support member 8, preventing arm element 4 from being pushed through support member 8 which slidably supports intermediate portion 10 of arm element 4, i.e., arm element 4 can no longer move in first lateral direction P1 with base element 3. Instead, end 18 of arm element 4 is forced deeper into the cavity of base element 3, against the action of the biasing member, as shown in positions B and C.

[0060] In position C, the arm element 4 assumes its fully retracted state.

[0061] As the actuator shaft 6 continues to rotate in the counterclockwise direction P1 through positions D and E, the base element 3 pivotally coupled to the actuator shaft 6 moves in a second lateral direction indicated by arrow P3 opposite to the first lateral direction P2, while the end 7 of the base element 3 moves continuously in the first transverse direction P4, whereby the arm element 4 extends through the action of the biasing member, while the protrusion 12 maintains its engagement with the support member 8.

[0062] In position E, the arm elements 4 have again reached their fully extended state and the applicator head 11 has reached the application position.

[0063] Thus, as the device 1 is manipulated through positions A to E, the applicator head 11 is moved from the retrieval position to the application position, and simultaneously the arm elements 4 are moved from an extended state to a retracted state (positions A to C) and back to an extended state (positions C to E). As a result, the applicator head 11 can be caused to move along a substantially straight path when moved from the retrieval position to the application position.

[0064] Continued rotation of the actuator shaft 6 in the counterclockwise direction P1 from positions E through H causes the base element 3 to be initially moved (from positions E to G) in a second lateral direction P3, while the end 7 of the base element 3 is moved in a second transverse direction indicated by arrow P5 opposite to the first transverse direction P4, with the arm element 4 remaining fully extended. During this movement, the protrusion 12 is disengaged from the support member 8, and therefore the arm element 4 remains fully extended under the action of the biasing member.

[0065] Continued rotation of the actuator shaft 6 (from position G to H and then back to position A) causes the base element 3 to move in a first lateral direction P2 while the end portion 7 is continuously moved in a second transverse direction P5. During this movement, the protrusion 12 moves towards the support member 8 but does not engage with it, and therefore the arm element 4 remains in its fully extended state.

[0066] In position A, the arm elements 4 are in their extended state and the applicator head 11 has returned to its retracted position.

[0067] As the arm element 4 remains in its fully extended state through position EA, the applicator head 11 is moved along a curved path from the application position back to the withdrawal position.

[0068] 4 illustrates schematically the use of device 1 for affixing article 100 onto a moving object 200. Article 100 may be a drinking straw and object 200 may be packaging. The object moves on conveyor 300 in a feed direction indicated by arrow P6.

[0069] This figure shows the device 1 with the applicator head 11 in the retrieval position. This figure also shows the device 1 in dashed lines with the applicator head 11 in the application position.

[0070] The figure further shows a drive means 14 in the form of a supply wheel that advances the article 100 to a position relative to the recovery position of the applicator head 11 so that the applicator head 11 can recover the article 100 from the drive means.

[0071] Rotation of the actuator shaft 6 about the first axis of rotation RA1 from position A to position E as shown in Figure 3 moves the applicator head 11 from the retrieval position to the application position. Retraction and subsequent extension of the applicator arm 4 during this movement causes the applicator head 11 to follow a generally straight path that allows for well-defined application of the article 100 onto the object 200.

[0072] The article 100 may be attached to an attachment surface of an object 200 that has been provided with an adhesive, such as hot melt, in an upstream station.

[0073] As shown in Figure 3, continued rotation of the actuator shaft 6 about the first rotation axis RA1 from position E back to position A moves the applicator head 11 from the application position back to the retrieval position, during which movement the arm element 4 is in its extended state, and therefore causes the applicator head 11 to follow a curved path initially having a component in the feed direction P6 of the moving object 200.

[0074] By matching the speed at which the applicator head moves along this component in the feed direction P6 with the feed speed of the object 200, the applicator head 11 can maintain engagement with the item 100 and, after applying the item 100, press the item 100 against the object 200 before being lifted back to the retrieval position.

[0075] Movement of the applicator head 11 along substantially straight and curved paths is indicated by dashed lines in the figures.
