Abstract
Description
[0001] This application relates to a bagging machine comprising two filling stations supplied alternately by the same empty bag supply station.
[0002] According to an embodiment visible on the figure 1 A bag 10 comprises first and second walls 10.1, 10.2, parallel to each other, connected by a bottom 10.3 and by gussets 10.4 along their sides. Alternatively, the first and second walls may be directly connected to each other along their lateral sides, either partially or fully. When empty, the bag has an opening 10.5 of varying size at the top. After filling, the opening 10.5 of the bag is closed. The bag 10 may include a zipper closure at its opening to allow it to be closed after opening. This type of zipper closure tends to reduce the cross-section of the opening 10.5. However, the smaller the cross-section of the opening 10.5, the longer the filling time.
[0003] According to different embodiments visible on the figures 2 à 4 A bagging machine, used to fill 10 bags one after the other, comprises a feeding station 12 for empty bags, a bag opening station 14 for a 10-inch bag, a filling station 16 for a 10-inch bag with product, a closing station 18 for a 10-inch bag, and a discharge system 20 for the filled bags. The 10-inch, 10-inch, 10-inch bags move one after the other from one station to the next in a direction of travel DD.
[0004] The opening station 14, positioned upstream of the filling station 16, allows a bag to be positioned in an appropriate position prior to its introduction into the filling station 16 and to open the bag.
[0005] According to a first embodiment visible on the figures 2 et 3 , the bags 10, 10', 10" are oriented so that their first and second walls 10.1, 10.2 are substantially parallel to the scrolling direction DD at the opening, filling and closing stations 14, 16 and 18.
[0006] According to a configuration visible on the figure 3 The feeding station 12 and the opening station 14 are aligned perpendicular to the direction of travel DD. At the feeding station 12, the empty bags 10 are positioned flat, with the first and second walls 10.1, 10.2 of the bags being substantially horizontal. At the opening, filling, and closing stations 14, 16, 18, the bags 10, 10', 10" are positioned vertically along the direction of travel DD, with the first and second walls 10.1, 10.2 of the bags 10, 10', 10" being substantially vertical and parallel to the direction of travel DD.
[0007] The opening station 14 includes a static spreading system which has first and second parts 14.1, 14.2 positioned on either side of the bag immobilized at the opening station 14 and configured to occupy a close state in which the bag is closed and a spread state in which the bag is open.
[0008] According to the first embodiment visible on the figures 2 et 3 The bagging machine includes a first transfer system 22 configured to take an empty and horizontal bag 10 from the feeding station 12, rotate it and position it vertically in the opening station 14. In addition, the bagging machine includes a conveying system 24 configured to take three bags 10, 10', 10" positioned respectively at the opening, filling and closing stations 14, 16, 18, transfer them according to the direction of travel DD and then position them respectively at the filling and closing stations 16, 18 and the discharge system 20.
[0009] According to a second embodiment visible on the figure 4 , the bags 10, 10', 10" are oriented so that their first and second walls 10.1, 10.2 are substantially perpendicular to the direction of travel DD at the opening, filling and closing stations 14, 16, 18; the feeding station 12, the discharge station 20 as well as the opening, filling and closing stations 14, 16, 18 being aligned along the direction of travel DD.
[0010] At the feeding station 12, the empty bags 10 are positioned flat, with the first and second walls 10.1, 10.2 being substantially horizontal. At the opening, filling and closing stations 14, 16, 18, the bags 10, 10', 10" are positioned vertically and perpendicular to the direction of travel DD, with the first and second walls 10.1, 10.2 of the bags 10, 10', 10" being substantially vertical and perpendicular to the direction of travel DD.
[0011] Regardless of the method used, all the bags pass by, step by step, successively from one station to the next.
[0012] Filling and closing stations 16 and 18 are the two stations where the bags must remain stationary for as long as possible. This time is longer the smaller the bag's opening section.
[0013] Therefore, the rate of the bagging machine depends essentially on the time spent filling and / or closing the bags at the filling and closing stations 16, 18 and the bag opening section.
[0014] To increase the bagging speed, one solution is to install two bagging machines. This solution is not satisfactory because it is relatively expensive and increases the required floor space.
[0015] Another solution involves installing a carousel, particularly at the filling station 16, to increase the filling rate. This solution is unsatisfactory because it complicates the filling process. Furthermore, it is not suitable for all bag sizes.
[0016] The present invention aims to remedy all or part of the drawbacks of the prior art.
[0017] For this purpose, the invention relates to a bagging machine configured to fill bags and comprising at least one empty bag feeding station located at the level of a straight line, at least one opening station, at least one filling station, at least one closing station and at least one discharge station.
[0018] According to the invention, the bagging machine comprises first and second filling stations positioned respectively at the first and second lines parallel to the direction of travel, the latter being positioned equidistant from the first and second lines. In addition, the opening station has a first zone positioned at the first line, a second zone positioned at the second line, and a central zone positioned between the first and second zones and in line with the feeding station.The opening station also includes first and second spreading systems configured to open the bags one after the other, as well as a first transverse conveying system, to which the first and second spreading systems are connected, configured to move alternately between a first position in which the first and second spreading systems are respectively positioned in the central zone and the second zone and a second position in which the first and second spreading systems are respectively positioned in the first zone and the central zone.
[0019] This solution makes it possible to increase the rate without increasing the number of stations as in the case of two bagging machines, the empty bag supply station feeding two filling stations.

[0029] According to a first embodiment visible on the figure 5 The first and second zones 50.1 and 50.2 are respectively positioned at the first and second filling stations 38 and 40. The central zone 50.3 is positioned between the first and second filling stations 38 and 40. As illustrated in the figure 9 The first and second filling stations 38, 40 and the various zones 50.1, 50.2, 50.3 of the opening station 50 are positioned in the same transverse plane (perpendicular to the direction of travel DD). According to this first embodiment, the opening station 50 is partially nested with the first and second filling stations 38, 40, which contributes to obtaining a more compact assembly.

Thus, the opening station 50 and its various zones 50.1, 50.2, 50.3 are offset along the longitudinal direction relative to the first and second filling stations 38, 40. According to this second embodiment, the opening station 50 is separate from the first and second filling stations 38, 40.

[0042] Following, as illustrated in part (C) of the figure 5 The empty bag S1, positioned in the second spreading system 54, is transferred to the second filling station 40. During this transfer, the second spreading system 54 moves from the closed to the open state, causing the bag S1 to open. S1 is then ready for filling. Simultaneously, the first spreading system 52 returns to the central zone 50.3 of the opening station 50 and moves from the open to the closed state, ready to receive a new bag S6 positioned at the feeding station 34.
[0043] Following, as illustrated in part (D) of the figure 5 The empty and closed bag S6 is introduced into the first spreading system 52 of the opening station 50 located in the central zone 50.3.

The bags S1, S2 present in the second filling station 40 and the second closing station 44 remain static.
[0044] Following, as illustrated in part (A) of the figure 5 The empty bag S6, positioned in the first spacing system 52, is transferred to the first filling station 38. During this transfer, the first spacing system 52 moves from the closed to the closed state, causing the bag S6 to open. The bag is then ready for filling. Simultaneously, the second spacing system 54 returns to the central zone 50.3 of the opening station 50 and moves from the closed to the closed state to be ready to receive a new bag.
[0045] This cycle, comprising the different stages previously described and visible in parts (A), (B), (C) and (D), is subsequently repeated.
[0046] The operating principle of the bagging machine 30 according to the second embodiment is described with regard to the figure 6 .
[0047] At a first moment visible on part (A) of the figure 6 , an empty and closed S1 bag is positioned at the feeding station 34.
[0048] Following, as illustrated in part (B) of the figure 6 The empty, sealed bag S1 is introduced into the second spreading system 54 of the opening station 50.

Bags S5, S6, and S7, located in the first zone 50.1 of the opening station 50, the first filling station 38, and the first closing station 42, remain stationary.
[0049] Following, as illustrated in part (C) of the figure 6 The empty bag S1, positioned in the second spacing system 54, is transferred to the second zone 50.2 of the opening station 50. During this transfer, the second spacing system 54 moves from the closed to the closed state, causing the bag S1 to open. S1 is then ready for filling. Simultaneously, the first spacing system 52 returns to the central zone 50.3 of the opening station 50 and moves from the closed to the closed state, ready to receive a new bag S8 positioned at the feeding station 34.
[0050] Following, as illustrated in part (D) of the figure 6 The empty and closed bag S8 is introduced into the first spreading system 52 of the opening station 50. In parallel, the bags S5, S6, S7 present in the first zone 50.1 of the opening station 50, the first filling station 38 and the first closing station 42 are respectively transferred to the first filling station 38, the first closing station 42 and the first evacuation station 36. The bags S1, S2, S3 present in the second zone 50.2 of the opening station 50, the second filling station 40 and the second closing station 44 remain static.
[0051] Following, as illustrated in part (A) of the figure 6 The empty bag S8, positioned in the first spacing system 52, is transferred to the first zone 50.1 of the opening station 50. During this transfer, the first spacing system 52 moves from the closed to the closed state, causing the bag S8 to open. The bag is then ready for filling.

[0053] According to the invention, each bag remains stationary for the duration of two steps at the first and second filling and closing stations 38, 40, 42, 44. This solution makes it possible to increase the rate or increase the filling rate while maintaining the rate compared to existing equipment, which corresponds to packaging economy while limiting the number of stations compared to the number of stations of two bagging machines.
