Background Art

A variety of automatic machine is used for the liquid product (such as fruit juice and soft drink), the granular product, the ground product or powdered products continuously packaging into the bag in the form of flexible container. Usually, the existing implementation of the automatic packaging machine is used for forming the heat-sealable material forming a production line of the bag, and is used for the filling of the product to be packed in the bag or of the production line is connected with the front of a packaging production line forming a production line.

Patent application ES2226518 discloses such an automatic packaging machine, comprising: a bag forming apparatus or for supplying in advance device of the bag made of, determining the actual longitudinal axis; for conveying the bag in order to be used for the packaging of the device; and a package for packaging bag device. The device used for conveying the bag is connected with the bag forming apparatus, or the bag transfer device for use in supplying pre-of the bag made of device connection. Device for transmitting of the bag of the bag along the closed track of the conveying and guiding mechanism, the closed track by the 1st and 2nd half-circumference part of a semi-circular peripheral portion, said 1st and 2nd half-circumference part of the semi-circular peripheral portion at the inner surface face each other and with the aid of straight portion of the coupling at the ends of the corresponding, disposed therein so as to form the packing bag device useful for the oval internal, the conveying and guiding mechanism to determine the actual longitudinal axis. And wherein the used for forming the bag and forming a production line, the production line is longitudinally arranged relative to each other compared with those of the machine, although this kind of machine to save space, but still desired by a packaging production line relative to the space occupied by the packing ability is further improved.

Horizontal packaging machine is also usually provided with a container to form a module and a packing module, the container forming module and packaging module to cooperate, in order to make the manufacturing of the container formed in the module are individually or batch-transferred to the packing module, the implementation in the packaging module is opened, for example, filling and closing operation of the container.

The hitherto known packaging module includes a series of longitudinally aligned work station, said work station in implementation of the above-mentioned opened at the same time, filling and sealing operation. To this end, flexible container according to the distance of the work station are separated from each other are arranged to form longitudinal queue, intermittently so as to form the packaging line of forward movement, thus the container from the one station to the next station. To this end, the machine is provided with a transmission frame, the transmission frame while at the same time maintaining all of the flexible container packaging production line, and the between two adjacent station transmitting said flexible container at the same time.

Through example, Patent literature ES2257180 discloses an automatic packaging machine can be applied to the container transfer apparatus, this type of container is provided with a conveying equipment and is provided with a packaging production line forming a production line, the used for forming a production line, from a sheet of heat-sealing material is formed into the bag forms of flexible container, the container in the package production line in a longitudinal direction at least in the corresponding station filled and closed.

The arrangement of this type is of the, container or flexible container group of mobile is not continuous, but intermittent. The container in the process in different packaging station and the speed of the forward movement speed can be obtained compared with the very limited, because when the container moves intermittently forward, if the speed is not controlled, comprising in a container of liquid, granular or powdery product of the ripple effect produced by the may be spilled out of the container before the closure.

On the other hand, the container for the packing operation is performed on the non-linear machine, such as application EP1043233-A1 disclosed in the machine. This type of machine is similar to the processing of the known packaging machine rigid bottle , the rigid bottle in its opening experience, for example, fluid-filled, gas injection and capped operation, each kind of operation to the corresponding vertical shaft of the rotating wheel in the form of implementation in the apparatus, wherein the periphery of the wheel for in each of the receiving space to receive a bottle in a plurality of receiving spaces, each of the bottles from one wheel is transmitted to the receiving space of the receiving space adjacent to the wheel, in order to perform subsequent packaging operation.

In particular, application EP1043233-A1 discloses a device for filling and packing into the bag forms of flexible container of the machine. The machine comprises a can be placed at various vertical shaft of the rotating wheel into the device, fluid-filled device and a sealing device, the vertical shaft by the rotating wheel to the wheel of the vertical shaft of the form of the coupling device or the transmission device are connected with each other. When handling a container in the shape of a flexible bag, when the non-rigid container, each bag are placed in the bottom and two vertical walls constitute a rigid support element, said vertical wall is spaced the distance can be adjusted, in order to be adjusted in order to be suitable for the width of the bag. The rigid supporting element in the bag to bag for each wheel is performed on the operation required stability and rigidity, and the supported on the supporting element on the bag from the group consisting of a wheel can be from the receiving position of the receiving position of the next wheel, and the deformation of the bag. Therefore, transmitted from one wheel to the other wheel is not only of the bag, but also a bag is placed the support element itself. Each wheel (or the operating wheel, or coupling device or the transfer device of the wheel) in its periphery with a plurality of receiving space or booking position, so that at each and receives in the space receiving a set of support element-bag, said the device at that time to maintain the group of mobile. For example, the coupling device or the transmission device has two receiving space, a receiving space for receiving an operating wheel group of supporting element-bag and transmit it to the next wheel, and the other the return of empty a receiving space, in order to receive the next group. It is worth noting that, each coupling device are arranged between the two operating wheel, coupling device with said operating the center of the wheel to ALIGN the center of the wheel.

Although this type of machine and linearly disposed compared with the space-saving machine, however, the machine between the operating element of the wheel must be comprises a coupling device, with each loop need of a container in a large number of support elements of the same quantity, in order to be used for the flexible container. Furthermore, special attention must be paid to the control of different wheel delay between, thus when the is supported on the supporting element on the bag on after the operation has been completed, subsequent round of the receiving space to become empty for receiving the support element, in order to implement the subsequent operation. And, by means of a coupling device in the operating wheel to the other operation attention must be paid to the process, so as to enable the support element to leave a series of in-bag receiving element and to another receiving element does not experience a sudden mobile, this forced to take preventive measures, and to provide special device, in order to transfer in smooth manner.

Therefore, the need for such a packaging module, which can be applied in any type of flexible container and product, and there is no need to make these container in order to be able to always performing an operation on the container supporting on the support element, the packaging module is provided with a prominent management capability, and can be formed after the flexible container in a fast and safe manner of packaging operation, and the packaging module occupies the space is as small as possible.
