DETAILED DESCRIPTION OF EMBODIMENTS
[39] Figures IA to ID show an embodiment of part of a stringbag packing apparatus 1 according to the invention, for packing a stringbag 10 into a packing box 20, and various stages of providing the stringbag 10 from an extended configuration E10 shown in figures 1A and 2A into a harmonica (or zigzag) configuration Z10 shown in figure ID and 2B. The stringbag 10 is a string of bags 11, and comprises a plurality of bags 11 connected with interconnections 12 to one another in sequence along a string extension direction D10. An interconnection 12 between two connected adjacent bags 11 in the stringbag extends along a connection direction D12 that is transverse to the string extension direction D10. Each bag 11 in the stringbag 10 has a length direction D11 as seen along a bag length L 11 between interconnections 12 to adjacent bags in the stringbag or as seen between an end 19 of the stringbag 10 and an interconnection 12 to an adjacent bag in the stringbag.
[40] The stringbag 10 in the extended configuration E10 thereof has the length direction D11 of each bag 11 in the stringbag 10 extending along and in the same direction as the string extension direction D10. In a harmonica configuration Z10, the stringbag has the length directions D11 of adjacent bags 10 in the stringbag 10 alternating along the string extension direction D10. Figures 1A and 2A show the length directions D11 of the individual bags 11 within the stringbag 10 extending parallel to and in the same direction as the string extension direction D10. The length direction D11 of the individual bags 11 is taken as being in the same direction as the string extension direction D10 as seen in the extended configuration of the stringbag.
Figures 1D and 2A with the stringbag 10 in a harmonica configuration show the length directions D11 of the individual bags 11 alternating along the string extension direction D10, which means that the length directions D11 of adjacent backs are transverse to the string extension direction D10 and have a component pointing in opposite directions. The length directions DI1 being transverse to the string extension direction D10 is intended to mean that there is a length direction component that is perpendicular to the string extension direction, while there may be a length direction component along the string extension direction D10. A harmonica configuration may have various degrees of “harmonicazation”, with more or less of a length direction component perpendicular to the string extension direction.
[41] Figure 1 A shows that the stringbag 10 in the extended configuration E10 is supplied on a supply arrangement 100 of the packing apparatus 1 in a conveying direction DI, with the string extension direction DIO along the conveying direction DI. The supply arrangement comprises 100 a supply conveyor 110 for supplying the stringbag 10 in the extended configuration E10 at the discharge end 101 of the supply arrangement 100 at a first speed V100 at a discharge height H100. The supply conveyor 110 is running at the first speed V 100 to supply the stringbag 10 at the first speed V 100 at the discharge end 101.
[42] The stringbag 10 is subsequently received on the formation surface 210 of formation conveyor 200 extending in the conveying direction D1. The formation conveyor 200 is configured and arranged for receiving the stringbag 10 at the first speed V100 from the discharge end 101 of the supply arrangement 100 on the formation surface 210. The formation surface 210 of the formation conveyor 200 is driven at a second speed V200 that is lower than the first speed V100. A ratio of the second speed V200 with respect the first speed V100 is dependent on the application and may, for instance, be set in dependence a the bag length L11 in the stringbag.
When received on the formation surface 210, the stringbag is conveyed on the formation surface in the conveying direction at the second speed V200. The connection directions D12 of the interconnections 12 between adjacent bags 11 in the stringbag 10 extend along the formation surface 210 and transverse to the conveying direction D1 (and transverse to the string extension direction D10). The stringbag is received at a receiving height H200 on the formation surface 210 below the discharge height H100. The distance d between the discharge height H100 and the receiving height H200 on the formation surface where the stringbag is received is smaller than the length L11 of the bags 11 in the stringbag 10.
[43] Figure 1B shows that a leading end of a leading bag in the stringbag 10 conveyed in the conveying direction D1 has been received at the receiving height
H200 on the formation surface 210. The length direction L11 of the leading bag is directed downwards since the receiving height H200 is below the discharge height H100. The leading end of the leading bag in contact with the formation surface 210 travels at the speed V200. The opposing end of the leading bag is pushed by the subsequent bag 11 in the stringbag at about the first velocity V100 since it moves upwards as well and since the subsequent bag still travels at the first speed V 100 on the supply conveyor 110 of the supply arrangement. Figure 1C shows that the interconnected trailing end of the second bag and the leading end of the third bag in the stringbag 10 have been received on the formation surface 210 of the formation conveyor. Since the formation surface 210 is moving at the second speed V200 smaller than the first speed V100, the length directions D11 of the leading first bag and the third bag in the string bag 10 are directed downwards while the length direction D11 of the second bag is directed upwards. This process continues until all bags 11 of the stringbag 10 have been received on the formation surface to obtain the stringbag in the harmonica configuration Z10 on the formation surface 210 of the formation conveyor 200 as shown in figure 1D. The length directions D11 of adjacent bags in the stringbag 10 are alternating along the string extension direction D10 in the harmonica configuration Z10. When the full stringbag 10 has been received on the formation surface 210 in the harmonica formation Z10, movement of the formation surface is stopped to allow the stringbag in the harmonica configuration to be provided into a packing box.
[44] To prevent sliding of the bags 11 in the stringbag 10 on the formation surface 210, the formation surface is configured to have non-slip properties. When the bags would slide over the formation surface, the harmonica configuration may become lost. The figures show that the formation surface is configured to have corrugations as seen along the conveying direction D1 to prevent sliding of bags of the stringbag 10 over the formation surface.
[45] Figures 3A to 3D shows various further embodiments of a supply arrangement 110 of the packing apparatus 1. The embodiments of figure 3A to 3D show an extension of the embodiment shown in figures 1A to 1D by having a pull pusher 130 for pulling and pushing the stringbag 10 in the conveying direction D1.
The pull pusher 130 comprises the supply conveyor 110 and a presser 120 for pressing the stringbag, in operation, on the supply conveyor 110. The presser 120 can be adjusted in the vertical direction to set a pressing force onto the bags 11 of the stringbag for setting an adequate pulling and pushing action by the pull pusher 130. The stringbag 10 is moved by pulling into the pull pusher 130 and pushing out of the pull pusher. The pull pusher is arranged to discharge the stringbag, in operation, at the discharging end 101 of the supply arrangement 100. The presser 120 of the embodiments of figures 3A, 3B and 3D comprises a series of rollers 121 parallel to the supply conveyor 110.
[46] The presser 120 of the figure 3C embodiment has one larger roller 121 with resilient hairs at its external circumference (external surface) to exert a pressing force onto the bags 11 of the stringbag 10. Optionally, one or both of the supply conveyor and the presser may present resilience for exerting a resilient force onto a stringbag conveyed between the supply conveyor and the presser. This allows for variations in thicknesses of bags in the stringbags. On the one hand it prevents that too less pressure is exterted onto a bag, and on the other hand it prevents too much friction so that a bag might get stuck between presser and supply conveyor. The supply conveyor and/or the roller(s) 121 can have a resilient external circumference for exerting a resilient force onto a stringbag (10) conveyed between the supply conveyor and the presser. In the embodiment shown, the resilient external circumference is provided only on the roller by resilient hairs. Such resilient hairs or flaps may be provided onto the supply conveyor as well, or on both the supply conveyor and the roller(s).
[47] The embodiments shown in figures 3B, 3C and 3D have a feeder 140 for providing the string bag 10 to the pull pusher 130 and feeding a leading end of the stringbag into the pull pusher 130. The embodiment of figure 3B has a feed conveyor 150 in line with the supply conveyor 110. The feed conveyor 150 can be operated on a slightly lower speed than the first speed V100 of the supply conveyor 110 so that the stringbag 10 is pulled from the feed conveyor for ensuring the extended configuration of the stringbag when discharging from the supplying arrangement 100.
[48] The embodiment of figure 3C reverses an initial feed direction of the stringbag 10 from the feed conveyor 150 by shooting the stringbag from the feed conveyor 150 into a U-shaped (as seen in the vertical plane) guiding track 160 with rollers 161, which guides the leading end of the stringbag into the pull pusher 130, after which the feed conveyor may be operated at lower speed to allow pulling by the pull pusher 130. The guiding track 160 is a driven track for moving the stringbag along and on the track towards the pull pusher 130. To that end the rollers 161 of the guiding track are driven rollers for moving the stringbag on the track. The rollers 161 can be mutually rotationally connected so that a motor connected to only one roller 161 will drive all rollers of the guiding track for moving the stringbag 10 along the guiding track 160 from the feed conveyor 150 to the push puller 130. Figure 3C only shows a rotation arrow for some rollers 161 to indicate that they are rotationally driven, but all or most rollers 161 are driven rollers. Driving the guiding track enhances
[49] The embodiment of figure 3D has a lift 170 for picking up the stringbag 10 at an intermediate position between both ends 19 of the stringbag, and lifting the stringbag and forwarding the leading end of the stringbag to the pull pusher 130. The lift, in the embodiment shown, has a chain 171 guided over two pulleys 172 and a horizontal bar 173 connected to the chain. The bar 173 picks up the stringbag 10 when moving upwards on the right-hand part of the chain 171.
Subsequently the bar 173 moves with the chain over the upper pulley 172, after which the bar 173 moves downward with the chain and feeds the leading end of the stringbag into the pull pusher 130. The bar 173 is lowered further and the stringbag 10 is pulled into the pull pusher 130. When moving over the upper pulley 172 to the left, the leading end of the stringbag forwarded to the push puller 130.
[50] Figures 4A to 4C schematically show to provide the stringbag 10 in the harmonica formation Z10 into a packing box 20. Figure 4A corresponds to figure 1D, and shows a side view of the stringbag 10 in the harmonica formation Z10 on the formation surface 210 but with a movable end stop 250 for the string bag. The movable end stop 250 can be set at an offset position along the conveying direction for each subsequent stringbag 10 in the harmonica configuration on the formation surface 210 to allow collecting subsequent stringbags in a nesting configuration on a collection surface 310 as is shown in figure 4B. The end stop 250 defines an end position of the stringbag in the harmonica configuration on the formation surface, and can be actively set at a different position for each string bag.
[51] Figure 4B shows a top view of part of the stringbag packing apparatus corresponding to figure 4A, but with formation conveyor 200 and supply arrangement on either side of a collection surface 310. A pusher 260 is present for each formation conveyor 200 for pushing the string bag 10 from the formation surface 210 onto the collection surface 310 The pusher 260 is embodied as a movable wall for moving a stringbag in the harmonica configuration from the formation surface 210 just on the collection surface 310. Figure 4B shows that two other stringbags 10 in the harmonica configuration have been provided earlier onto the collection surface 310 from the formation surface 210. The pusher 260 just provides a stringbag from the formation surface 210 onto the collection surface 3 10, after which another pusher 320 associated with the collection surface is moved downward to subsequently push one or more stringbags provided from the formation surface 210 on the collection surface 310 further onto the collection surface.
Stringbags 10 in the harmonica configuration may be collected on the collection surface 310 from the formation conveyors 200 on either side of the collection surface. When a stringbag is formed in the harmonica configuration on the formation surface of a respective formation conveyor 200, the movable end stop 250 is positioned such that a stringbag is formed in the harmonica configuration on the formation surface at a position so that adjacent stringbags collected on the formation surface 310 are in a nesting configuration. In the nesting configuration, the string extension directions of adjacent stringbags are parallel to and next to one another and peaks and valleys of the harmonica configuration of one stringbag are besides valleys and peaks, respectively, of the harmonica configuration of an adjacent stringbag. When the required number of stringbags have been collecting in the nesting configuration on the collection surface, both pushers 320 are moved towards each other to have the nested stringbags collected densily. The top view of figure 4B shows two stringbags 10 in a nesting configuration on the collection surface 310 and a third stringbag 10 still on the formation surface 210 but at a position to allow a nesting configuration with what will become the adjacent stringbag on the collection surface. Figure 4C shows adjacent stringbags 10 in a nesting configuration in side view.
[52] After a number of stringbags 10 have been provided and densily collected in the nesting configuration on the collection surface310, a packing arrangement 400 takes the densily collected stringbags in the nesting configuration from the collection surface and transfers them into a packing box 20 as shown in figure 4C. The packing arrangement has a fixed end wall 411 and a movable end wall 412 to clamp the densily collected stringbags in the nesting configuration along the string extension directions. The packing arrangement has opposing side walls that are both movable to clamp the densily collected stringbags in the nesting configuration transverse to the string extension directions. Although figure 4C shows a cross-section, a movable side wall 413 is shown in dashed line. Figure 4C is only a schematic representation of a number of collected stringbags in the harmonica configuration and nesting configuration in the packing arrangement 400.In the embodiment shown, the end walls and the side walls are part of the packing arrangement 400 for taking and transferring the stringbags 10 from the collection surface 310 into the packing box 20. The packing box 20 can be positioned, for instance, to the side of the collection surface 310 opposite the formation surface 210.
However, many other ways can be envisioned for providing stringbags in the harmonica formation, and nesting configuration, from the formation surface 210 into a packing box 20.
