Abstract
Description
- The invention relates to an infeed device configured to transform flattened packaging material to an erected sleeve, as well as a method for performing such transformation.
- Infeed devices are provided in various types of manufacturing, such as in the packaging industry. Here it is well known to use the infeed device as a tool in which carton-based blanks (i.e. flattened packaging material) are transformed to sleeves ready to receive plastic tops forming the spout of the final package.
- Instead of providing the blanks in a magazine from which the infeed device receives a series of consecutive blanks, it has been suggested to feed a flattened tube to the infeed device and to cut a blank from the continuous tube immediately before the cut blank enters the infeed device. One problem with such solution is that while the tube is running vertically, the infeed device is transporting the erected sleeves in a horizontal plane. Hence a motion conversion is required, increasing the complexity and bulkiness of the infeed device.
- In view of this it would be advantageous to provide a less complex and less bulky infeed device which is still capable of receiving a vertically moving flattened blank, to erect them to sleeves, and to transport the sleeves in a horizontal plane.
- It is an object of the present solution to at least partly overcome one or more of the above-identified limitations of the prior art. In particular, it is an object to reduce the required height of the infeed device.
To solve these objects an infeed device is provided. The infeed device comprises an inlet station configured to provide a series of consecutive blanks, an infeed carousel arranged vertically below the inlet station and having a plurality of receiving devices distributed along the circumference of the infeed carousel. Each receiving device is configured to receive a blank from the inlet station and to transform the blank to an erected body. The infeed device further comprises a conveyor having a plurality of carriers configured to receive a respective erected body from an associated receiving device, and wherein the conveyor is arranged vertically above the infeed carousel. - According to another aspect of the present solution, a method for feeding a blank of a packaging material is provided, where the method comprises
- moving the blank in a vertical direction to a receiving device arranged on a rotating infeed carousel,
- erecting the blank to a tubular body while the blank is transported by the motion of the receiving device, and
- delivering the erected body to a carrier of a conveyor arranged vertically above the receiving device.
- Still other objectives, features, aspects and advantages of the invention will appear from the following detailed description as well as from the drawings.
- Embodiments of the invention will now be described, by way of example, with reference to the accompanying schematic drawings, in which
-
Fig. 1 is a schematic view of how a blank in the form of a flattened tube is transformed to a final package; -
Fig. 2 is a schematic view of the transformation steps performed by an infeed device according to an embodiment; -
Fig. 3 is an isometric view of an infeed device according to an embodiment; and -
Fig. 4 is a schematic view of a method according to an embodiment. - With reference to
Fig. 1 the process of transforming aflattened tube 10 of packaging material is illustrated. Thetube 10 is initially having a cylindrical shape, indicated by theuppermost portion 12 of thetube 10. The flattened shape is e.g. achieved by clamping two opposite sides of thetube 10 against each other. Such clamping may be performed using twojaws 20a-b arranged such that a gap is formed therebetween. Thetube 10 may be continuously fed through the gap and as thejaws 20a-b are moved towards each other, as is indicated by the block arrows inFig. 1 , thecylindrical portion 12 will be flattened. Downstream the gap a cutting device (not shown) may be arranged to cut a sequence offlattened tube portions 30 from thecontinuous tube 10. Eachtube portion 30 forms a blank which is intended to form a longitudinal main body of a package. In order to produce the final package a series of steps is performed. - Firstly, the blank 30 is handled by an infeed device which will later be described with reference to
Figs. 2 and3 . The purpose of the infeed device is to transform the flat blank 30 to an erectedbody 40, here in the form of a tubular body having two opposite open ends. Once the tubular shape is formed theerected body 40 is transported to an injection molding station. In this station one end of theerected body 40 is provided with aplastic top 50, thus closing that end of thebody 40. Thereafter, a threadedcap 55 is applied onto a corresponding thread on the neck portion (not shown) of theplastic top 50. - Once the
plastic top 50 is in place, thesemi-finished package sterilization device 60, such as an electron beam sterilization device, in the open-ended body 40. Other means of sterilization could also be used, such as introducing hydrogen peroxide (H2O2) or hot water vapour through thesterilization device 60 into the open-ended bod 40. Following sterilization, a fillingnozzle 70 is controlled to fill the open-ended package semi-finished package end 82. This results in a finishedpackage 80. - The operating principle of the
infeed device 100 is further shown inFig. 2 , although being only schematically illustrated. Theinfeed device 100 comprises, except for aninlet station 110, aninfeed carousel 120, and aconveyor 140. Comparing with the manufacturing principle described with reference toFig. 1 , theinlet station 110 is configured to provide theblanks 30, while the infeedcarousel 120 as well as theconveyor 140 are configured to receive theblanks 30 and to deliver theerected bodies 40 to the injection molding station where theplastic top 50 is added to theerected body 40. - As can be seen in
Fig. 2 theblanks 30 are provided at theinlet station 110 at the left of the drawing. Each blank 30 is fed vertically downwards, i.e. in the direction of the arrow 35, to the infeedcarousel 120. The infeedcarousel 120, inFig. 2 represented by a linear projection, has a number ofreceiving devices 130. A receivingdevice 130 is positioned to receive a blank 30 approaching the infeedcarousel 120, and to transport the blank 30 as the infeedcarousel 120 rotates. During this transportation agate 132 of thereceiving device 130 is configured to engage with the blank 30 and to erect thetubular body 40. Erection may e.g. be accomplished by means of thegate 132 urging thelateral ends 32a-b of the blank 30 to move towards each other, thus opening the blank 30 to form anerected body 40. Thegate 132 may be constructed in various ways, e.g. as two opposing grippingmembers 132 being moveable towards each other for erecting the blank 30 or as a claw-like member contracting to force the blank 30 to erect. Thegate 130 may preferably be programmed to engage with the blank 30 during the vertical movement, and to continuously reduce the vertical speed of the blank 30 during engagement with thegate 130 so that a smooth, and almost instant transition between a vertical and a horizontal movement is accomplished. - When the
erected body 40 has obtained its desired tubular shape it is moved vertically upwards, i.e. opposite the direction of the arrow 35. Eachreceiving device 130 is for this purpose provided with aplunger 134, or other suitable means being configured to push the erectedbody 40 to a position where theerected body 40 engages with acarrier 142 of the conveyor 140 (shown inFig. 3 ). Thecarrier 142 moves along theconveyor 140 at a vertical level above thereceiving devices 130 of the infeedcarousel 120. During some time the horizontal movement of thecarrier 142 is synchronized with the horizontal movement of thereceiving device 130, which means that thegate 132 will have time to release theerected body 40 while theerected body 40 is also carried by thecarrier 142 of theconveyor 140. Thecarrier 142 may e.g. be a sleeve-like member of which the diameter is adjustable. For example, the diameter of the sleeve-like member may have a first value dimensioned to allow theerected body 40 to be arranged onto the sleeve-like member, and a second value being larger than the first value and being dimensioned to apply a radially outwardly directed force on the inside of theerected body 40, such that theerected body 40 remains onto thecarrier 142 during transport by means of theconveyor 140. - Accordingly, the infeed
carousel 120 acts as an intermediate transport means for converting a vertical movement of a blank 30 to a horizontal movement of anerected body 40. - Now turning to
Fig. 3 an example of aninfeed device 100 is shown in more detail. As can be seen, theconveyor 140 is arranged to move in a horizontal plane. It may be formed as a belt conveyor. Theconveyor 140 passes a number ofwheels conveyor 140, but also to control the speed of theconveyor 140 as well as the position of thecarriers 142 relative theinfeed carousel 120. The driven wheel (not shown) may e.g. be the injection molding station. - The
carriers 142 are attached toholders 144 which are clamped to theconveryor 140 and which themselves are evenly distributed along theconveyor 140, such that the distance between two adjacent holders 144remains constant as theconveyor 140 is running. In contrast, thecarriers 142 attached to theholders 144 are offset in relation to each other, such that on outer curves, such as the outer curve OC above theinfeed carousel 120, the distance between twoadjacent carriers 142 measured as the arc length between their two centers is larger than the distance between twoadjacent holders 144. On inner curves, such as the inner curve IC carousel 160, the distance betweenadjacent carriers 142 is reduced to roughly half of the distance on the outer curve. The larger distance on the outer curve ensures that the sleeves pass the conveyor wheel and "hit" thereceving devices 130. The larger distance also makes it easier to access theconveyor 140 and its elements by tools for the purpose of readjustment and service. Also, the distance between twoadjacent carriers 142 is somewhere between the distance of theadjacent carriers 142 on the outer curve OC and the inner curve IC. To give some example distances for one embodiment of the present solution, the distance between twoadjacent holders 144 on the straight part of theconveyor 140 may be selected to be 190 mm, while the distances between twocarriers 142 on the outer curve may HM be 258 mm and 135 mm on the inner curve IC. During a part of the horizontal movement of theconveyor 140, i.e. a part of the horizontal transportation path of theconveyor 140, said part being the outer curve OC, acarrier 142 will be synchronized and aligned with one of the receivingdevices 130 of theinfeed carousel 120. - The
infeed carousel 120 is a rotary device having a plurality of receivingdevices 130 arranged at its periphery. Theinfeed carousel 120 is preferably configured to rotate at a constant speed and the operation of thegates 132 as well as theplungers 134 may be controlled bycam structures parts devices 130 are also arranged at an equal distance between them; preferably the distance between twoadjacent receiving devices 130 is the same as the distance between twoadjacent carriers 142 of theconveyor 140 which means that the vertical alignment between acarrier 142 and areceiving device 130 can be maintained for as long as theconveyor 140 follows the rotary motion of theinfeed carousel 120. - The
inlet station 110 is arranged at a position behind the transportation path of theconveyor 140, such that thetube 10 or the separated blanks 30 (not shown inFig. 3 ) do not interfere with thecarriers 142 distributed along theconveyor 140 but may pass immediately to areceiving device 130 arranged vertically below. Theinlet station 110 is for this purpose provided with acutting device 112, as well asdrive device 114 configured to accelerate a blank 30, once cut from thetube 10, vertically downwards to the receivingdevice 130 of theinfeed carousel 120. Thedrive device 114 may e.g. operate by friction. - Now turning to
Fig. 4 , amethod 200 for converting a vertical movement of a flattenedtube 10 of packaging material to a horizontal movement of an erectedbody 40 will be described. Themethod 200 is thus configured to feed a blank 30 to downstream equipment such as an injection molding station or similar. - In a first step 202 a blank 30 is provided by cutting a flattened
tube 10 of packaging material. Thisstep 202 is preferably repeated continuously such that a series ofconsecutive blanks 30 are provided. Themethod 200 then continues by moving, instep 204, the blank 30 in a vertical direction downwards to areceiving device 130 arranged on arotating infeed carousel 120. - In a following
step 206 the blank 30 is erected to atubular body 40 while the blank 30 is transported by the motion of the receivingdevice 30, and instep 208 the erectedbody 40 is delivered to acarrier 142 of aconveyor 140 arranged vertically above the receivingdevice 130. From thecarrier 142, the erectedbody 40 is ready to be transported to the downstream equipment. - While the initial movement of the blank 30 is purely vertical, the
infeed carousel 120 converts this vertical motion to a horizontal motion before the blank 30 is transferred to thehorizontal conveyor 140 arranged vertically above theinfeed carousel 120. - For smooth transfer of the erected
body 40 between theinfeed carousel 120 and theconveyor 140 the speed of theconveyor 140 is preferably synchronized with the speed of theinfeed carousel 120, and more precisely the angular speed of the receivingdevices 130 of theinfeed carousel 120. - From the description above follows that, although various embodiments of the invention have been described and shown, the invention is not restricted thereto, but may also be embodied in other ways within the scope of the subject-matter defined in the following claims.
