Definitions

  • 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.
  • carton-based blanks i.e. flattened packaging material
  • sleeves ready to receive plastic tops forming the spout of the final package.
  • 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.
  • a method for feeding a blank of a packaging material where the method comprises
  • the tube 10 is initially having a cylindrical shape, indicated by the uppermost portion 12 of the tube 10.
  • the flattened shape is e.g. achieved by clamping two opposite sides of the tube 10 against each other. Such clamping may be performed using two jaws 20a-b arranged such that a gap is formed therebetween.
  • the tube 10 may be continuously fed through the gap and as the jaws 20a-b are moved towards each other, as is indicated by the block arrows in Fig. 1 , the cylindrical portion 12 will be flattened. Downstream the gap a cutting device (not shown) may be arranged to cut a sequence of flattened tube portions 30 from the continuous tube 10.
  • Each tube 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.
  • the blank 30 is handled by an infeed device which will later be described with reference to Figs. 2 and 3 .
  • the purpose of the infeed device is to transform the flat blank 30 to an erected body 40, here in the form of a tubular body having two opposite open ends.
  • an erected body 40 is transported to an injection molding station. In this station one end of the erected body 40 is provided with a plastic top 50, thus closing that end of the body 40. Thereafter, a threaded cap 55 is applied onto a corresponding thread on the neck portion (not shown) of the plastic top 50.
  • the semi-finished package 40, 50 is ready for sterilization. This may e.g. be performed by inserting a 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 the sterilization device 60 into the open-ended bod 40. Following sterilization, a filling nozzle 70 is controlled to fill the open-ended package 40, 50 with the desired content. As a final step for manufacturing, the still open end of the semi-finished package 40,50 is folded and sealed forming a closed end 82. This results in a finished package 80.
  • a sterilization device 60 such as an electron beam sterilization device
  • H2O2 hydrogen peroxide
  • a filling nozzle 70 is controlled to fill the open-ended package 40, 50 with the desired content.
  • the still open end of the semi-finished package 40,50 is folded and sealed forming a closed end 82. This results in a finished package 80.
  • the operating principle of the infeed device 100 is further shown in Fig. 2 , although being only schematically illustrated.
  • the infeed device 100 comprises, except for an inlet station 110, an infeed carousel 120, and a conveyor 140.
  • the inlet station 110 is configured to provide the blanks 30, while the infeed carousel 120 as well as the conveyor 140 are configured to receive the blanks 30 and to deliver the erected bodies 40 to the injection molding station where the plastic top 50 is added to the erected body 40.
  • the blanks 30 are provided at the inlet 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 infeed carousel 120.
  • the infeed carousel 120 in Fig. 2 represented by a linear projection, has a number of receiving devices 130.
  • a receiving device 130 is positioned to receive a blank 30 approaching the infeed carousel 120, and to transport the blank 30 as the infeed carousel 120 rotates.
  • a gate 132 of the receiving device 130 is configured to engage with the blank 30 and to erect the tubular body 40. Erection may e.g.
  • the gate 132 may be accomplished by means of the gate 132 urging the lateral ends 32a-b of the blank 30 to move towards each other, thus opening the blank 30 to form an erected body 40.
  • the gate 132 may be constructed in various ways, e.g. as two opposing gripping members 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.
  • the gate 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 the gate 130 so that a smooth, and almost instant transition between a vertical and a horizontal movement is accomplished.
  • Each receiving device 130 is for this purpose provided with a plunger 134, or other suitable means being configured to push the erected body 40 to a position where the erected body 40 engages with a carrier 142 of the conveyor 140 (shown in Fig. 3 ).
  • the carrier 142 moves along the conveyor 140 at a vertical level above the receiving devices 130 of the infeed carousel 120.
  • the carrier 142 may e.g. be a sleeve-like member of which the diameter is adjustable.
  • the diameter of the sleeve-like member may have a first value dimensioned to allow the erected 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 the erected body 40, such that the erected body 40 remains onto the carrier 142 during transport by means of the conveyor 140.
  • the infeed carousel 120 acts as an intermediate transport means for converting a vertical movement of a blank 30 to a horizontal movement of an erected body 40.
  • the conveyor 140 is arranged to move in a horizontal plane. It may be formed as a belt conveyor.
  • the conveyor 140 passes a number of wheels 150, 152, of which at least one may be a driven wheel not only configured to drive the conveyor 140, but also to control the speed of the conveyor 140 as well as the position of the carriers 142 relative the infeed carousel 120.
  • the driven wheel (not shown) may e.g. be the injection molding station.
  • the carriers 142 are attached to holders 144 which are clamped to the converyor 140 and which themselves are evenly distributed along the conveyor 140, such that the distance between two adjacent holders 144remains constant as the conveyor 140 is running.
  • the carriers 142 attached to the holders 144 are offset in relation to each other, such that on outer curves, such as the outer curve OC above the infeed carousel 120, the distance between two adjacent carriers 142 measured as the arc length between their two centers is larger than the distance between two adjacent holders 144.
  • outer curves such as the outer curve OC above the infeed carousel 120
  • the distance between two adjacent carriers 142 measured as the arc length between their two centers is larger than the distance between two adjacent holders 144.
  • inner curves such as the inner curve IC carousel 160
  • the distance between adjacent 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" the receiving devices 130.
  • the distance between two adjacent carriers 142 is somewhere between the distance of the adjacent carriers 142 on the outer curve OC and the inner curve IC.
  • the distance between two adjacent holders 144 on the straight part of the conveyor 140 may be selected to be 190 mm, while the distances between two carriers 142 on the outer curve may HM be 258 mm and 135 mm on the inner curve IC.
  • a carrier 142 will be synchronized and aligned with one of the receiving devices 130 of the infeed carousel 120.
  • the infeed carousel 120 is a rotary device having a plurality of receiving devices 130 arranged at its periphery.
  • the infeed carousel 120 is preferably configured to rotate at a constant speed and the operation of the gates 132 as well as the plungers 134 may be controlled by cam structures 136a, 136b or other suitable means for controlling periodic movement patterns of these parts 132, 134.
  • the receiving devices 130 are also arranged at an equal distance between them; preferably the distance between two adjacent receiving devices 130 is the same as the distance between two adjacent carriers 142 of the conveyor 140 which means that the vertical alignment between a carrier 142 and a receiving device 130 can be maintained for as long as the conveyor 140 follows the rotary motion of the infeed carousel 120.
  • the inlet station 110 is arranged at a position behind the transportation path of the conveyor 140, such that the tube 10 or the separated blanks 30 (not shown in Fig. 3 ) do not interfere with the carriers 142 distributed along the conveyor 140 but may pass immediately to a receiving device 130 arranged vertically below.
  • the inlet station 110 is for this purpose provided with a cutting device 112, as well as drive device 114 configured to accelerate a blank 30, once cut from the tube 10, vertically downwards to the receiving device 130 of the infeed carousel 120.
  • the drive device 114 may e.g. operate by friction.
  • a method 200 for converting a vertical movement of a flattened tube 10 of packaging material to a horizontal movement of an erected body 40 will be described.
  • the method 200 is thus configured to feed a blank 30 to downstream equipment such as an injection molding station or similar.
  • a blank 30 is provided by cutting a flattened tube 10 of packaging material. This step 202 is preferably repeated continuously such that a series of consecutive blanks 30 are provided.
  • the method 200 then continues by moving, in step 204, the blank 30 in a vertical direction downwards to a receiving device 130 arranged on a rotating infeed carousel 120.
  • step 206 the blank 30 is erected to a tubular body 40 while the blank 30 is transported by the motion of the receiving device 30, and in step 208 the erected body 40 is delivered to a carrier 142 of a conveyor 140 arranged vertically above the receiving device 130. From the carrier 142, the erected body 40 is ready to be transported to the downstream equipment.
  • the infeed carousel 120 converts this vertical motion to a horizontal motion before the blank 30 is transferred to the horizontal conveyor 140 arranged vertically above the infeed carousel 120.
  • the speed of the conveyor 140 is preferably synchronized with the speed of the infeed carousel 120, and more precisely the angular speed of the receiving devices 130 of the infeed carousel 120.
