Description

Device and method for making composite bag

The present invention relates to the manufacture of storage pockets made from tubular fabrics, and in particular to a device or an apparatus and method for making multi-component pockets, wherein the packaging pockets have openings embedded therein and in the multi-component pockets The ends are joined together by an internal mesh belt.

Multi-component woven pockets include packaging pockets with moisture-resistant mesh linings (or a lining insert), necessary for the storage of moisture-perishable materials such as sugar granules, chemicals, or other similar materials. Currently, multi-component bags consisting of an outer bag or cover and an inner mesh belt preferably made of plastic film are mainly produced in a manual process, resulting in lower productivity. Furthermore, the quality of the pockets is substandard and variable as it depends on the skill of the operator. Furthermore, on the edges at the open ends of the pockets formed during the cutting-to-length process, there is a risk that the webbing will become detached, particularly where the pockets are made of uncoated woven fabrics Down. These sidebands continue close to the edge, parallel to the cutting line, can be displaced in the direction of the cutting line or lose their parallelism and can thus slip off completely from the fabric. This occurrence is very detrimental to the filling and further disposal of the pocket.

For this reason, the open ends of these pockets are typically folded by hand and the folded edges are attached to the underlying fabric layer comprising the embedded mesh lining, for example sewn or glued or joined together using heat staples or seams or a combination thereof, where a hem type is obtained at the open end of the pocket and thus a clean sealing edge.

However, this disadvantage is that this folding and joining procedure requires a high expenditure of work and material (sewing thread), and results in a significant material loss from the pocket material during the folding procedure.

The present invention therefore aims to avoid the disadvantages mentioned above. In particular, the present invention aims to automate the production of a multi-component pocket and minimize production costs and material losses during production.

In particular, there exists a need to provide a method and apparatus for producing a multi-component bag or a composite bag comprising an outer cover (1) and a mesh belt liner insert (2), This allows it to maintain the moisture integrity of the liner, thereby making it suitable for specific storage applications involving the storage of moisture perishable items. There is also a need to provide a procedure that allows flexibility in joining the mesh belt liner insert along with the top edge of the outer cover.

Object of the present invention

It is therefore an object of the present invention to provide a procedure that allows flexibility in joining the mesh belt lining insert together with the top edge of the outer covering.

Another object of the present invention is to provide a device for making a composite bag (C) having: an outer covering (1) made of a first cylindrical garter (1A); and an inlay Piece (2), which is made of a second cylindrical garter (2A) to carry out the aforementioned procedure.

Yet another object of the present invention is to provide a composite bag (C) having a sealed outer cover cut sheet (1C), a sealed insert cut sheet (2C) being embedded into the In the sealed outer cover cut sheet (1C) and wherein the outer cover and the liner insert are joined together at their edges.

A composite bag (C) made of an outer cover (1) and a lining insert (2) embedded into it is also called a multi-component bag (see Figure 1). As shown in Figure 2, the outer cover (1) has two layers (1', 1") and the lining insert (2) has two layers (2', 2"). Both the outer cover and the lining insert can be made from a cylinder garter. The walls of the composite bag (C) comprise a layer (1', 1") of the outer cover (1) and a layer (2', 2") of the lining insert (2). The composite bag (C) has two ends - a top end (T) and a bottom end (B). The woven fabric for making the outer cover includes sidebands woven in the warp and weft directions. The cylindrical garter is cut into pieces. These sidebands continue close to the edge, parallel to the cutting line, can be displaced in the direction of the cutting line or lose their parallel and can thus slip completely off the fabric. This occurrence is very detrimental to the filling and further disposal of the pocket. The present invention provides a procedure that allows flexibility in joining the mesh belt liner insert together with the top edge of the outer cover to overcome the aforementioned drawbacks.

A composite bag (C) made of an outer cover (1) and a lining insert (2) embedded into it is also called a multi-component bag (see Figure 1). As shown in Figure 2, the outer cover (1) has two layers (1', 1") and the liner insert has two layers (2', 2"). Both the outer cover and the lining insert can be made from a cylinder garter. The walls of the composite bag (C) comprise a layer (1', 1") of the outer cover (1) and a layer (2', 2") of the lining insert (2). The composite bag (C) has two ends - a top end (T) and a bottom end (B). The individual components of the composite bag (C), namely the outer cover (1) and the lining insert (2) also have two ends respectively: a top end (4 - the top end of the outer cover (1) and 4A - the lining The top edge of the insert (2)) and a bottom end (3 - the bottom end of the outer cover (1) and 3A - the bottom end of the lining insert (2)). In the context of the present invention, the ends refer to the area near the end of the bag.

The outer cover (1) is made of woven or non-woven thermoplastic fabric. The woven fabric is produced by weaving sidebands in the warp and weft directions. The mesh belt lining insert (2) can also be made of plastic film, woven or non-woven thermoplastic fabric in the form of a cylinder (eg a garter). The liner (2) may be in the form of a bag that is opened at one end (eg, the top end) but sealed at the other end (the bottom end) to form a moisture integrity seal. In other words, the seal is such that it is substantially moisture resistant.

In one aspect of the invention (see Figures 1, 2A and 8), the width and length of the lining insert (2) are slightly greater than the respective widths and lengths of the outer cover (1). in this content In the network, the length of the outer cover (1) is taken as the length between its open end and the seal of the outer cover provided at its other end. In the final product (ie, the composite bag (C)), the extra length of the liner insert (ie, the length of the liner insert that is longer than the outer cover) accumulates at the bottom end (B) (see Figure 6) or may be The outer covering (1) is spread out over the length. Similarly (see also Figure 6) the extra width (ie the amount by which the width of the lining insert is wider than that of the outer cover) accumulates anywhere or spreads over the width of the outer cover (1).

When the outer covering (1) is made of a woven fabric made of sidebands and uncoated, the sidebands continue close to the edges, parallel to the cutting line, and may transversely (or in the direction of the cutting line) Displaced away from each other or loses their parallelism, and can thus slip off completely from the fabric. To overcome this problem, the present invention discloses a device or a method for making a multi-component or composite bag comprising an outer cover (1) and a mesh lining insert (or just the lining insert). piece or lining), and the webbing lining insert is joined with the outer cover at their respective top ends (4, 4A) or pocket openings, thereby preventing lateral displacement of the webbing.

In order for the lining insert (2) of the composite bag (C) to join the outer cover (1) at its top end (4/4A), it is necessary to combine the two layers (1', 1" of the outer cover) ) and the layers (2', 2") of the lining insert (2) are separated from each other to form an opening (Fig. 2). In another aspect thereof, the present invention provides a mechanism and method for opening the mouth of a composite bag (C). Importantly, layers 1' and 2' and layers 1" and 2" are open in their relaxed state, or separated from each other as in pairs (ie layers 1'/2' together and layers 1"/2 ” together) so that the mouth or end of the composite bag (C) is fully opened, as shown in FIG. 3 . It should not be the case that layers 1' and 1" are pulled apart from each other, while layers 2' and 2" remain in a collapsed state so that the port cannot be opened (see Figure 2).

A separate member or device may be operated using pneumatic, hydraulic, electrical or any possible electromechanical configuration capable of lifting (or moving) both layer pairs (1'/2' and 1"/2") individually (S/H - see Fig. 2A), at the open end of the mesh belt lining insert (2), the layers (2', 2") of the mesh belt lining insert (2) are lifted or separated from each other. As a For example, the separation member may comprise gripping units provided at the ends of the garters (S/H - see Fig. 2A), which gripping units are capable of gripping the outer covering (1) layer and/or the lining insert using suction Layer (2). Details of this suction member are known to those skilled in the art.

The inventors have also realised that when a liner (2) is embedded in an outer cover (1 ) such that the layers (2', 2") of the liner insert (2) are simply separated from each other, an outer cover will necessarily result The layers (1', 1") of things are separated from each other. Therefore, in yet another aspect of the present invention, a method is disclosed for entering a separating member into the layers (2', 2") of the liner insert (2). To facilitate this, along the layers (2', 2") of the cover Widths of 1', 1") provide for layers (2', 2") of lining inserts (2) made in layers (1', 1") of outer covering (1) of any geometry and size A hole (6) of sufficient area exposed to facilitate attraction to one layer (2' and 2") of the mesh belt liner insert through the above-mentioned members. The adequacy of the exposed area is based on the ability to grip the liner ( 2) The required content of the grabbing member of the separation member of the layer (2', 2") is determined. A hole (6) is preferably provided near the end of the composite bag (C) that will remain open. This allows the corresponding layers (1', 1") of the outer cover (1) to remain together with the layers (2', 2") of the mesh belt lining insert (2) - ie forming a layer pair 1'/2' and 1"/2" - by the process of separating the layers (1'/1" and 2'/2") near the opening.

The invention is not limited to the deployment of holes (6) in the woven fabric - in the case of no holes (6) in the woven fabric a suction configuration may be sufficient to attach the layers (1' and 1") of the outer bag (1) together with The corresponding layers (2' and 2") of the mesh belt lining insert (2) are pulled together. This configuration ensures that the woven bag layers (1' and 1") are pulled together with the corresponding layers (2' and 2") embedded in the mesh belt liner (2).

The other side of the woven bag can be left open or permeable by tying, ultrasonic welding, gluing, heat stitching, seaming, or a combination thereof, or through surfaces that can be used to separate the two sides of the bag Any possible member of the junction closes the other side.

When the mouth of the composite bag is opened (Fig. 2), an electromechanical arrangement pushes the inner tool (5) between the layers (2' and 2") separated by the sealed liner cut sheet (2C) so that the inner tool (5) The layers (2' and 2") of the sealed lined cut sheet (2C) are completely isolated from each other so that the layers (2', 2") do not touch each other when the lift/movement configuration is released. Usually a flat solid plate The inner tool (5) in the form of (for example made of metal) also provides a physical support to any tool that forms a joint tied to the edge of the mouth or the edge of the layer of outer bag and mesh lining insert (UC , LC, UI, LI) near the top end (4/4A). As shown in Figure 2A, the edges of the layers (1', 1") of the outer cover cut sheet (1) are defined as the sealed outer The upper edge (UC) of the cover cut sheet (1C) and the lower edge (LC) of the sealed outer cover cut sheet (1C). Similarly, the edges of the liner insert (2) are defined as the upper edge (UI) of the sealed liner cut sheet (2C) and the lower edge (LI) of the sealed liner cut sheet (2C). For example, if an ultrasonic method is used to make joints at the aforementioned edges (UC, LC, UI, LI) of the layers of the sealed outer cover cut sheet (1C) and the sealed liner insert cut sheet (2C) , the inner tool (5) can act as an anvil.

On the open end of the bag into which the inner tool is embedded (see Figure 3A), the two sides of the open end of the woven fabric layers (1' and 1") and the mesh lining layers (2' and 2") are joined together - also That is, the edges of layers 1', 2' are joined together, and the edges of layers (1", 2") are joined together - using an electromechanical arrangement like ultrasonics, heat sealing, hot tacking or spray adhesive. To achieve this, the top edges of layers 1' and 2' are aligned or lined or matched to each other and then sealed together. Similarly, the top edges of layers 1" and 2" are lined or matched together and sealed. The sealing of both pairs can be performed simultaneously or separately.

Figure 7 shows the composite bag (C) of the present invention. The area (J) near the top end (T) shown as the grey area indicates that the layers (1'/2' and 1"/2") are over which are sealed or bonded together joint area or joint. It should be noted that in the context of juxtaposition, although an edge can be considered theoretically to have zero width, the joining of edges is intended to convey that the junction can have a certain width. The seal may thus have a measurable width or it may simply be a line seal or a point direct seal or a serrated seal.

The method of the present invention is now disclosed in a step-by-step manner. The method will be better understood with reference to Figure 5, which shows steps in lower case next to the arrows (as used to indicate steps within the scope of the appended claims). The product obtained by any particular step is indicated in capital letters inside the box.

The method of making a composite bag (C) according to the present invention comprises the following steps.

Two rolls of garter are provided: a first roll of garter (1A), which is used to make the outer covering article; and a second roll of garter (2A), which is used to make the lining cutout. At a first cutting station (FC), outer covering cutting pieces (1B) of desired length are cut from the first cylindrical garter (1A). At a first sealing station (FS), the top end of the outer cover cut sheet (1B) is sealed to make a sealed outer cover cut sheet (1C). At least one hole (6) is formed in each of the layers (1', 1") of the outer cover cutting sheet (1B). On a second cutting station (SC), from the second circle A lining cut piece (2B) is cut from the garter belt (2A). At a second sealing station (SS), the top end of the lining cut piece (2B) is sealed to make a sealed liner cut piece (2C). At a first embedding station (FIS), a first intermediate composite with a mouth (C3) is produced by embedding the sealed liner cut sheet (2C) into the sealed outer cover cut sheet (1C) Bag (C1). At this stage, the top edge of the sealed liner cut piece (2C) protrudes out of the sealed outer cover cut piece (1C) because the length of the former is greater than the length of the latter. And at this stage , the sealed liner cut sheet (2C) may still be in a collapsed state inside the sealed outer cover cut sheet (1C) (see Figure 2).

However, the top edge of the sealed liner insert cut sheet (2C) and the top edge of the sealed outer cover cut sheet (1C) need to be sealed together for each of their corresponding layers - namely layer 1' Join layer 2' at its top edge and layer 1" with layer 2" at its top edge. To facilitate the splicing operation, it is necessary to align the top edge of the sealed outer cover cut sheet (1C) with the top edge of the sealed liner cut sheet (2C) at an alignment station (AS) (see Figure 2B). ), which produces a second intermediate composite bag (C2) in which the top edges of layers 1'/2' are aligned with each other. Similarly, the top edges of layers 1"/2" are also aligned with each other. However, to facilitate the edge alignment step, and also to facilitate the splicing operation, it was further found necessary to open the port (C3) so that the layer pairs (1'/2' and 1"/2") were well separated. At a layer separation station (LS), layer separation operations are performed using separation members or devices of the type known to those skilled in the art. Usually, for the purpose of layer separation, the devices use a vacuum, using a separation device (S - see Fig. 6), the layers (1', 1" and 2', 2 of the cut sheets (1B and 2B) ") to form layer pairs (1'/2' and 1"/2") and open the port (C3). Next, insert the inner tool (5) into the now open port (C3). The inner tool embedment ensures that the layer of sealed liner cutting blade (2C) and the layer of sealed outer cover cutting blade (1C) are fastened together as much as possible before the splicing of the edges is performed. Edge alignment can be facilitated after the inner tool (5) has been embedded. The device used for edge alignment may be one known to those skilled in the art, which essentially induces a relative movement between the two layers (1'/2' and 1"/2") so that the respective edge be put together or aligned.

Next, the edges of the dyads (1'/2' and 1"/2") are joined together to form an upper sealing edge (U) and a lower sealing edge (L) using sealing methods known to those skilled in the art ), thereby forming the composite bag (C) with a sealed edge at its top end (T).

In a preferred embodiment of the method of making a composite bag (C) (see Figure 5A), the steps of separating the layers and embedding the liner tool are in a different order. In this embodiment, the lining Immediately after the insertion of the inner insert (2) into the outer cover (1), the step of layer separation is carried out. Next, the inner tool (5) is embedded in the opening (C3) formed as a result of one of the previous steps. This is followed by the steps of edge alignment and layer pairing to form the upper and lower sealing edges (U and L).

The present invention also discloses an apparatus for making a multi-component or composite bag (C). The apparatus has the following stations to perform the various stages of the method disclosed herein and illustrated in FIG. 4 . The device has a first cutting station (FC) for making the first cylindrical garter (1A) into outer covering cutting sheets (1B) of the desired length. The apparatus also has a first sealing station (FS) for sealing a top end of the outer cover cutting blade (1B) to make a sealed outer cover (1C). A second cutting station (SC) is also provided for making the second cylindrical garter (1B) into a lining cutting sheet (2B) of a desired length. A second sealing station (SS) is provided in order to seal a top end of the liner cut sheet (2B) thereby making a sealed liner cut sheet (2C). Next, in order to embed the sealed liner cut sheet (2C) into the sealed outer cover cut sheet (1C) to produce a first intermediate composite bag (C1), a first embedding station (FIS) is provided . At this stage, the top edge of the sealed liner cut piece (2C) protrudes beyond the sealed outer cover cut piece (1C) because the length of the former is greater than the length of the latter. An alignment station (AS) is therefore provided to align the bottom edge of the sealed outer cover cut sheet (1C) and the bottom edge of the sealed liner cut sheet (2C) of the first intermediate composite bag (C1) with each other to produce a second intermediate composite bag (C2). A layer separation station (LS) is provided with a separation device (S) for separating the layers (1', 1" and 2', 2") of the dicing sheets (1B and 2B) to form layer pairs (1'/2' and 1"/2"), and an opening (C3) is formed at the bottom end of the second intermediate composite bag (C2). Next, in order to facilitate the splicing operation, a second inserting station (SIS) is provided for inserting an internal tool (5) into the opening (C3). Finally, a third sealing station (TS) is provided for sealing the edges of the dyads (1'/2' and 1"/2") to a to form an upper sealing edge (U) and a lower sealing edge (L).

In a preferred embodiment of the apparatus (see Figure 4A), the layer separation station (LS) may be positioned directly downstream of the first insertion station (FIS). Here, after the lining insert (2) has been embedded in the outer cover (1), the layer separation device (S) at the layer separation station (LS) separates the layer 1'/2' with the layer 1"/ 2" to form an opening (C3) into which the inserting tool (5) is inserted at the second inserting station (SIS).
