Description

Packing Case Packing Method, Packing Case Erecting Method, and Corresponding
Apparatus
FIELD OF THE INVENTION
[01] The invention relates to a packing case packing method, and corresponding apparatus, for packing a content, such as a loose product, perforated bags containing a loose product, articles like bags or cases containing a product, and the like, into a packing case, wherein the packing case has a packing case height as measured between opposing first and second sides of the packing case.
BACKGROUND OF THE INVENTION
[02] Packing case packing methods and corresponding apparatus are widely employed for packing a content of products into packing cases, which are generally card board boxes, for shipment. The size of the packing cases is generally chosen specifically for the content to be packed. However, it may occur that the size of a packing case does not fit the content. In some applications a varying content is packed in a packing case of a fixed size, while any space not filled by the content may be left open or is filled with a dedicated open space filler like one or more air cushions. Effectively, a lot of air is transported in such instances.
[03] In another application, a content of which the volume may change over time is packed into packing cases. This may, for instance, apply to perforated bags of frozen and yet unfried French fries. When filling the bags with the French fries, quite some air is filled into the bags as well and the French fries are not closely packed in the bags. Subsequently, the bags are packed in packing cases. The size of the packing cases can be chosen to fit a content of a number of such bags with French fries, but during shipping the French fries will become more closely packed and air will escape. This will leave an empty headspace above the content. Generally, a number of packing cases with content are stacked and shipped together, and the content inside the packing cases contributes to the structural strength of the packing case and the stack of packing cases. Having an empty headspace above the content, will severely reduce the structural strength. The content can be compacted so that no empty headspace remains. However, with some products, like French fries, the volume of the content may vary with time. The water content of potatoes, and thus of the French fries, will change with the season, which causes the volume to change for a given weight of the content. The size of packing cases, especially the height, should therefore preferably change over time to fit the content. Practically, the packing cases are limited to a number of sizes having a selected packing case height. Unfortunately, this may still cause an underfill and thus an empty headspace or an overfill of packing cases. Both are undesired.
[04] Methods and apparatuses are known to adapt the height of a packing case while the content is present inside the packing case. The height of the packing case is adapted 40 based on the content of the packing case at that moment by providing some machine parts into the packing case to adapt its height. This may damage the content, especially when bags such as the perforated bags with French fries are involved, but will generally also cause a slow-down of the packing case packing process. Both are quite undesired as well.

DETAILED DESCRIPTION OF EMBODIMENTS
[27] Figure 1 shows a blank 10B for finally making a packing case 20 through an intermediate (erected) preform 10 (10E). The blank 10B has four panels 13 and four first flaps 11 attached to first ends 13.1 of the panels. The panels 13 have second ends 13.2 opposing respective first ends 13.1 of the panels, and have side ends 13.3 connecting the first end second ends 13.1, 13.2. A series of four panels 13 is connected to one another at their respective side ends 13.3. A first panel in the series has an unconnected side end 13.3, while a last panel in the series has a flap 14 connected to one side end 13.3. The flap 14 is for allowing a connection of the last panel in the series to the first panel in the series by, for instance, gluing the flap 14 to the unconnected side end 13.3 of the first side panel in the series to form a preform 10 as is shown in figures 2, 3A and 3B.
[28] The preform 10 has four interconnected panels 13, which means that all side ends 13.3 of the panels are connected to an adjacent panel. In a flat state of the preform 10, two adjacent panels of the preform are lying on top of two other panels of the preform, which allows to make a pile P of preforms 10, as is shown in figures 2, 3A and 3B. A preform on top of the pile P can be taken from the pile by employing, for instance, a movable arm with a suction holder 110 of a packing case erecting apparatus 101 for erecting packing cases 20 from preforms 10. Such packing case erecting apparatus can be part of a packing case 40 packing apparatus for packing content into the erected packing cases 20.
[29] An erected packing case 20, as shown in a closed state in figures 8A and 8B, has opposing first and second sides 20.1, 20.2, and interconnected side walls 23 defining a circumference of the packing case. First and second flaps 11, 12 of the packing case are attached to opposing first and second ends 23.1, 23.2, respectively, of the side walls. The first and second ends of the side walls correspond to the first and second sides 20.1, 20.2, respectively, of the packing case for closing the first and second sides of the packing case.
The interconnected side panels 13 of the preform are associated with the interconnected side walls 23 of the packing case 20. The first ends 13.1 of the panels 13 and the first flaps 11 of the preform 10 correspond to the first ends 23.1 of the side walls 23 and the first flaps 21 of the packing case 20, respectively.
[30] Figures 2 and 3A show a preform 10 taken form the top of the pile P, while still making contact with the pile. This causes the preform to open so that the flat faces of the panels lying onto one another in the preform in the pile come out of contact. When the preform 10 taken by the suction holder 110 is raised at some distance from the pile, as shown in figure 3B, two beams 120 of the packing case erecting apparatus 101 come in and push from the sides against the preform so that adjacent panels make right angles with respect to one another. This corresponds to arranging the panels 13 of the preform 10 to have mutual positions corresponding to mutual positions of the side walls 23 of the packing case 20 with respect to one another. Subsequently, the first flaps 11 are closed to provide an erected preform having a closed first side 10.1 corresponding to the first side 20.1 of the packing case. The erected preform 10E has an open second side 10.2 opposing the closed first side 10.1 of the erected preform. Closure of the flaps 11 is only schematically indicated by arrows in figure 3B, and is achieved by appropriate guiding elements of packing case erecting apparatus 101, which are known as such.. Figure 4A shows an erected preform 10E.
[31] Figures 4A to 4C show the side walls 23 and the second flaps 22 of the packing case 20 being formed from the panels 13 of the erected preform 10E. A guide frame 190 with an internal frame 140 and an external frame 130 mounted thereon is moved with respect to the erected preform 10E along a direction from the second side 10.2 toward the first side 10.1 ofthe erected preform. The internal frame 140 is directly mounted on the guide frame 190, while the external frame 130 is mounted by guide frame brackets 195 on the internal frame 140. Figure 4A shows the state before movement of the external and internal frames toward the erected preform 10E. The internal frame 140 is, from the state as shown in figure 4A, provided into the erected preform, while the external frame 130 is provided around the erected preform, which is shown in figure 4B. A gap between the internal and external frames allows the panels 13 of the erected preform to pass there through while the internal and external frames move into and around the erected preform. Guide elements 135, 145 on the external and internal frames guide the second ends 13.2 of the panels 13 into the gap. At the same time a pressing member 170 arranged on the guide frame 190 is 40 extended with respect to the guide frame 190 for pressing against the inside of the first side 10.1 of the erected preform 10E to press the first side 10.1 against a supporting surface S, as is shown in figure 4B. This provides a well-defined position of the first side 10.1 for positioning the internal and external frame with respect to the first side 10.1. Efficiently, this may be part of the process for erecting the preform to press the flaps 13 forming the first side 10.1 against each other, for instance, with a glue in between or a tape provided over opposite flap ends to join the flaps to close the first end 10.1.
[32] The external and internal frames 130, 140 are positioned at a distance from the first side 10.1 which corresponds to a predetermined packing case height to set the packing case height H20 of the packing case 20 to be formed from the erected preform 10E. The scoring blades 150 are arranged on a side of the internal frame 140 which faces away from the first side 10.1 of the erected preform 10E. Especially, the distance of the scoring blades 150 with respect to the first side 10.1 corresponds to the predetermined packing case height. Cutting blades 160 mounted at the corners of the internal frame 140 cut the preform at corners of the erected preform 10E between adjacent connected panels from the second side 10.2 of the preform to a position where the score line 25 is to be provided in the panels.
Figure 7 shows the cutting in more detail.
[33] At the position of the predetermined packing case height H20, where the external and internal frames have reached their intended position with respect to the closed first side 10.1 of the erected preform 10E, the scoring blades 150 are moved outwards with respect to the internal frame 140, in the state as shown in figure 4B, to press the panels 13 of the erected preform 10E between the scoring blades 150 on one side of the panels and the external frame 130 on the other side of the panels, which provides a score line 25 in the panels at a distance from the first side 10.1 which corresponds to the predetermined packing case height H20. Subsequently, the scoring blades 150 are retracted again and the guide frame 190 with external and internal frames 130, 140 and pressing member 170 are retracted from the packing case 20 with open second end 20.2, which has now been formed from the erected preform 10E, as is shown in figure 4C and figure 5. The score line 25 and the cutting of the corners of the preform have now formed the side wall 23 and flaps 22 at the second side 20.2 of the packing case. Figures 6A and 6B show a top view on the external and internal frames 130, 140 with the scoring blades 150 in the retracted and extended positions, respectively. The scoring blades are moved through pressurized air cylinders 151.
Figure 6C shows a bottom view on the external and internal frames with the scoring blades in the retracted position.
[34] The erected packing cases 20 with open second end 20.2 are provided by the packing case erector apparatus onto a packing case conveyor 400 of a packing case packing apparatus. Figure 9 shows a packing case filling apparatus 102 of the packing case packing apparatus. In the embodiment shown in figure 9, an article conveyor 210 and the packing case conveyor 400 are arranged alongside one another. Articles in the form of perforated bags A with frozen French fries are conveyed on the article conveyor 210 and 40 picked from the article conveyor by pick-and-place delta robots 220 to be provided into the open packing cases 20 conveyed on the packing case conveyor 400. Figure 11A shows a number of perforated bags A with the frozen French fries stacked on top of one another in the open packing case 20 as the content C in the packing case 20. The content C of the stack of bags A projects from the open top end 20.2 of the packing case 20 due to an excess of air present in the bags and the French fries not being closely packed in the bags.
Compacting of the content C is required to fit the content in the packing case.
[35] After filling of the content C of perforated bags A with frozen French fries in the packing cases on the packing case conveyor 400, the packing cases 20 are provided by the packing case conveyor 400 to a compactor apparatus 103 of the packing case packing apparatus for compacting of the content C in the packing cases. The compactor apparatus 103 is shown in figure 10A. The packing cases 20 with open second end 20.2 and with an uncompacted content C are provided by the packing case conveyor 400 to a supply end 103.1 of the compactor apparatus 103. After compacting, the packing cases 20 with open second end 20.2 and compacted content C are discharged at a discharge end 103.2 of the compactor apparatus 103. Figure 10A only shows a packing case 20 at the discharge end 103.2 of the packing apparatus and a packing case further downstream on the packing case conveyor 400 for illustration purposes. Generally, in operation, a flow of packing cases with a content will pass over the packing case conveyor 400 with multiple packing cases on the packing case conveyer upstream of the supply end 103.1, multiple packing cases on the stretch 400.3 of the packing case conveyor in the compactor apparatus 103 and multiple cases on the packing case conveyer 400 downstream of the discharge end 103.2 of the compactor apparatus 103. The packing cases 20 shown in figure 10A have a compacted content C.
[36] Figures 11A and 11B schematically show a packing case 20 with an uncompacted content C and a compacted content C, respectively, of (yet unfried) frozen
French fries that have been provided in a number of perforated bags A. Air is also included into the bags while providing the French fries into the bags and the French fries are not closely packed at that moment. In the compacting process with the compactor apparatus 103, the air is forced out of the perforated bags and the French fries become more aligned parallel with the bottom of the packing case for a more dense filling of the bags. As a result, the content C of bags A with unbaked French fries occupies less volume in the compacted condition of figure 11B as compared to the uncompacted condition as shown in figure 11A, and a very efficient filling of the packing cases 20 is achieved. Actually, the whole volume of the packing case is filled, with the aim of no overfilling or underfilling of the packing cases. Figures 11A and 11B also show a pressing element 315 of a pressing arrangement 310 of the compactor apparatus 103 to assist in compacting the content to a level of a top edge provided by score line 25 of the packing case 20 so that flaps 22 of the packing case can be folded and closed over the content C. Compacting the content allows a much larger amount of product to be filled in the packing case and a much more stable 40 packing case with product filling for handling, transportation and storage purposes.
[37] The packing case conveyor stretch 400.3 of the packing case conveyor 400 as part of the compactor apparatus 103 has compactor roller bars 320. The compactor roller bars 320 act on the one hand to advance the packing cases 20 along the packing case conveyor 400. On the other hand, the compactor roller bars 320 are shaped to provide a shaking movement to the packing case in the vertical direction while rotating. An example of such shape is shown in figure 10B. The compactor roller bar 320 has a non-circular cross-section perpendicular to its rotation axis 321. All roller bars 320 of the compactor apparatus 103 act in synchronization to provide the up-and-down shaking movement to the packing cases being supported on the compactor roller bars. Pressing members 315 of a pressing arrangement 310 will exert a downward force onto the content C of the packing cases 20 supported on the compactor roller bars 140 while rotating. This causes the content C to compact from the uncompacted state as is shown in figure 11A to a compacted state as is shown in figure 11B. In the embodiment shown, the three pressing members 315 can be collectively moved up and down with respect to frame 317 of the pressing arrangement 310 through actuator 316. The actuator 316 is fixedly mounted on the frame 317, while the pressing members 315 are vertically displaceable with respect to the frame 317 of the pressing arrangement 310.
[38] In the yet uncompacted state of the content C, the pressing members 315 are lowered onto the content C until the weight of the pressing members 315 is supported by the content C. At that moment, the compactor roller bars 320 are put into rotation, which causes compaction of the content C by the joint action of rotation of the compactor roller bars 320 and the weight of the pressing members 315 on the content C. Reference is made to WO 2019/083360 A1, which is incorporated by reference into the present disclosure, for a more detailed description of the compactor apparatus shown in figure 10A,
[39] Figures 11A and 11B schematically show the compacting of the content C of bags with loose product, being perforated bags with frozen French fries in the embodied disclosed. The content height HC to which the content is compacted may vary over time.
When the loose product is a product like frozen French fries, the water content will vary during the season, which will cause a varying content height HC during the season. A feedback from the compactor apparatus 103 is used in setting the predetermined packing case height in the embodiment disclosed when it is determined that the content height HC has changed. For that purpose the height of the content in the packing case during compacting is monitored as is shown in figure 12.
[40] Figure 12 schematically shows the height h of the content in the packing cases 20 as a function of time t during the compacting process. At time t=0 the pressing members 315 have been lowered onto the content C and the compacting roller bars 320 are put into rotation. The height of the content C during compacting from an initial height h0 at the start at t=0 will follow a curve, of which the fall-off value h1 after a characteristic time t1 will be a measure for the final content height HC. Therefore, the fall-off value ht can be used 40 for determining the content height HC and the predetermined packing case height for a next batch of filling packing cases with content, as is done in the embodiment shown. The height is measured by having appropriate sensors 325 (only generally indicated) measuring the position of the pressing members 315 with respect to frame 317 of the pressing arrangement 310. In this fashion one can monitor the compacted content height HC over time, for instance, during the season when the water content of French fries will change, and adapt the predetermined packing case height to the changed content height, if required. This can be continuously carried out during the packing process, especially when such packing line runs day after day. The predetermined packing case height can be adjusted at any moment when it is deemed required, based on the continuously monitored content height HC.
[41] Alternatively, or when a packing line has not been operated for some time, the step of determining the height HC of the content can be executed during one or more separate steps of filling a packing case, or a partially erected preform corresponding to the packing case with an open second side, with the content provided therein. This determination of the height HC of the content can then be used for the step of setting the predetermined packing case height for one or more successive cycles of the steps of erecting, filling and closing the packing cases.
