    Bag coupling device. A set (10) for coupling seemingly closed bags (11) containing a product. The assembly (10) includes a conveyor (14) having a length (16) that travels in a transport direction (17). A compression device (24) can be adjusted to the respective distance from the length (17) by a "parallelogram" arrangement. The compression device (24) couples the bags (11) and compresses the bags (11) against the length (12), the sensors (33 and 34) providing a signal indicative of the depth of the bags (11) and, by therefore, an indicative signal of the bags (11).

    [0001]
    [0002] Bag coupling device
    [0003]
    [0004] TECHNICAL SECTOR
    [0005]
    [0006] The present invention relates to the packaging industry and, specifically, but not exclusively, to the packaging industry that uses vertical forming and filling packing machines that generate cereal bags.
    [0007]
    [0008] BACKGROUND
    [0009]
    [0010] In the packaging industry, vertical forming and filling machines are used to generate tightly sealed product bags. A concrete example is snack packaging.
    [0011]
    [0012] The bags are formed by the packaging machine, the packaging machine providing the bag with a longitudinal seal and two transverse sealings.
    [0013]
    [0014] If the seals are not formed properly, the quality of the food contained in the bag degrades. As a concrete example, in the manufacture of snacks, a portion of the snack being packaged can be placed in the seal, thereby degrading the quality of the seal.
    [0015]
    [0016] U.S.A. Patent Documents 6202476 and 6041646 describe devices that have the objective of detecting defective bags, specifically leaking bags.
    [0017]
    [0018] It is a disadvantage of the packaging apparatus set forth above that defective bags can be generated and not detected. However, an additional disadvantage is that its operation is intermittent and therefore slow.
    [0019]
    [0020] In addition to the above, as the bags are manufactured by the packaging machines, they are supplied to a subsequent conveyor. The bags can adopt a variety of configurations. This has the advantage of making it difficult to organize the bags so that they can be contained inside larger boxes or bags.
    [0021] OBJECT
    [0022]
    [0023] It is the object of the present invention to overcome or substantially improve at least one of the above disadvantages.
    [0024]

    [0063] BRIEF DESCRIPTION OF THE DRAWINGS
    [0064]
    [0065] Preferred forms of the present invention will now be described by way of example with reference to the accompanying drawings in which:
    [0066]
    [0067] Figure 1 is an assembly for coupling bags, the assembly being divided along the line 1 -1 of Figure 2; and
    [0068]
    [0069] Figure 2 is a schematic view, in side elevation, of the assembly of Figure 1.
    [0070]
    [0071] DESCRIPTION OF THE EMBODIMENTS
    [0072]
    [0073] The attached drawings schematically show an assembly 10 for coupling hermetically sealed bags 11 containing a product. As a concrete example, the bag 11 may be a bag containing snacks. The bag 11 would have a longitudinal seal 12 and hermetic closures 13 ends. Each bag 11 will have a predetermined volume and is tightly closed.
    [0074]
    [0075] The assembly 10 includes a conveyor 14. The conveyor 14 includes an endless belt 15 having an upper transport length 16 that travels in a transport direction 17. The length 16 extends, generally, horizontally between one end 18 of the end part and one end 19 of the initial part, the bags being transported in the direction 17 to the end 18 of the end part from which the bags 11 are supplied from the assembly 10. The bags 11 rest on the length 16, since the length 16 provides an upwardly oriented surface.
    [0076]
    [0077] The conveyor 14 also includes a motor / gearbox assembly 20 that drives the conveyor belt 15 in the direction 17 by means of a drive roller 21.
    [0078] The conveyor 14 includes a base 22 on which the belt 15 is mounted, while a compression device 24 is also mounted on the base 22. The compression device 24 couples the bags 11 and compresses the bags 11 against the length 16.
    [0079]
    [0080] The compression device 24 includes a loop element 29 which includes two parallel, separate, chain loops 25 which support, and between which it extends, a plurality of springs (elastic elements) 26. The springs 26 extend, in general , horizontally and transversely to length 16.
    [0081]
    [0082] The chain loops 25 are driven in the direction 27 so that the length 28 of the loop element 29 moves in the transport direction 17 at the same speed as the length 16, so that the lengths 28 and 16 move to the unison.
    [0083]
    [0084] The chain loops 25 pass around a crazy cogwheel assembly 30 as well as around a drive cogwheel assembly 31. The drive sprocket assembly 31 includes a motor 32 that is coordinated with the motor 20 so that the lengths 16 and 28 move in unison in the transport direction 17.
    [0085]
    [0086] Two sensors 33 and 34 are mounted with the device 24, with the sensor 34 separated from the sensor 33 in the direction 17 towards the end 18 of the end portion. Each of the sensors 33 and 34 detects the upper surface of the bag 11, in order to provide a signal that is an indication of the depth of the bag 11 and, therefore, of the volume of the bag 11. However, device 24 can operate with a single sensor 33 or 34.
    [0087]
    [0088] As the bags 11 pass in the direction 17, they are compressed by the springs 36. Consequently, if there is a leak in the bags 11, the volume of the bag 11 will decrease, so that when the depth of the bag is detected 11 via sensor 33, the reduced depth will be indicative of a bag 11 with a leak.
    [0089]
    [0090] When the bags 11 are compressed, the springs 36 are elastically deformed upwards, and return to their resting position when they are not coupled to a bag 11.
    [0091]
    [0092] The sensors 34 communicate with a central computer to identify the defective bags 11 so that they can be eliminated from the process.
    [0093] In addition to detecting leaks, the assembly 10 also provides the bags 11 with a more uniform configuration at the end 19 of the end portion. In particular, the springs 26 mate with the bags 11 so that the bags 11 adopt a more uniform configuration.
    [0094]
    [0095] The compression device 24 can be adjusted with respect to the distance from the length 16 by a "parallelogram" arrangement that includes a pair of connections 35, generally parallel. Each of the connections 35 is pivotally attached to the device 24, and pivotally attached to the base 22, so that the length 28 remains, in general, parallel to the length 16.
    [0096]
    [0097] The connections 35 are connected to the drive shafts 36 that move angularly around their longitudinal shafts by the drive device 23. The drive device 23 would include an electric motor and the gearbox assembly, and would work to ensure that the length 28 is located at a correct distance from the length 16 to match the size of the bags 11 being transported.
