Description

[Detailed description of the invention] Special pouches to enclose the product, as well as manufacturing each pouch from a continuous web to contain the product. Encapsulation method and device Technical field The present invention relates to the manufacture of packages such as special packages and sachets, and to each manufactured package. Concerning the characteristics of packaging products into sachets. For further details, special sachets are The invention enables the encapsulation of such products in connection with the specific products encapsulated therein. It's made to work.

Background of the invention In recent years, special packaging for products has come into use. those patches A cage is designed to enclose a specific product and is used to package such products. It is also used in cooking if the product is food. Such a special packaging is becoming increasingly difficult to manufacture. In addition, continuous The packaging materials are used to give the package characteristics unique to the product it encapsulates, making it ideal for cooking and serving. Improving distribution is even more difficult.

The manufacturer's concern is, of course, to find the most economical way to manufacture the packaging for each individual product. This means that Continuous web material without adding any other components , if it can be processed into individual packages, we will get much closer to the above objective. becomes. However, individual It is also desirable to add it to the package. This is not only beneficial but also uses people find it convenient.

Many manufacturing processes that process flexible web materials to produce individual packages and sachets and devices are known. These packages and sachets pass through the filling station on the production line. tion, end sealing station, etc. such a representative Machines are generally classified into horizontal machines and vertical machines. Furthermore, such The machine employs a means of continuously moving the web material through the processing station or move the web material intermittently to avoid breaks between runs. The machining process is controlled to be carried out at the end of the process.

Intermittent used to produce relatively complex food containment bags from continuous web materials An example of a horizontal manufacturing machine that operates in There is something disclosed in (Galatia). In such a process, the first The web material is folded to form two sidewall sections with a bottom gusset. bottom The part gusset extends between the two side walls and has a W-shape. after that , various heat-sealing and cutting processes are connected between the intermittent movement and movement of the web. Continuing, a special package with two compartments is produced. but , processing steps are carried out from both sides of the folded web, and each step involves both side walls and and the bottom gusset.

Other specialized packaging made from a continuous web of flexible material is National Patent No. 4774797 (Columridge et al.), U.S. Patent No. 4453370 No. 4,631,901 (Titchenall) and U.S. Pat. etc.). Columridge and Titchenall bags have a bottom gusset. It has The bottom gusset extends between the sidewalls during the manufacturing process of each bag. It is growing. Such gussets are traditionally known when the bag is filled. Construct a bulged or square end that looks like a square. Chan, etc. is a specified amount A complex process for manufacturing sealed individual sealed packets containing fluids of A heat fusion sequence is disclosed. Columridge et al., Titchenall, and Char. As in the case of the device disclosed by Galatia, processing Processing or manufacturing steps are performed equally on both sides of the bag.

Still other techniques for manufacturing individual bags from a continuous web of flexible material No. 3,829,007 (Ellipso). Ellipso The bag has two sides forming a bottom gusset with the ends folded back towards the side walls. Two folding steps are required. After this, a heat fusion process is performed on the bottom edge of the side wall. The bag is made to stand on its own. Each molding step for both sides of each bag will be performed once again.

Furthermore, in order to embody features that are more beneficial and convenient for the final user. As specialized packages are designed, such packages can be linked together. Not only can they be manufactured efficiently from continuous web materials, but they can also be manufactured using the simplest possible machines. It has been shown that such manufacturing can be carried out using standard speeds in today's industry. clearly desirable. However, the characteristics embodied in such package design As specialization increases, manufacturing equipment becomes more complex and manufacturing speeds generally become slower.

One of the important features desired in many specialized packages is ease of opening. This means that If the package is easy to open, the contents can be easily taken out.

Other desirable features include a handle that allows for controlled removal of the contents of the package. It has a protruding part, etc. Strips and strength that can be torn off It is well known to provide a linear part etc. that weakens the battery. By embodying easy-to-open features in special packages such as bags and sachets, is even more difficult to achieve. More specialized bags and sachets for specific products designed to encapsulate or to be easy to cook if the product is a food In this case, this difficulty is compounded.

U.S. Patent No. 4,454,979 (Ikeda et al.) discloses a method for making the bag easier to open. A laminate bag is disclosed that includes a take-out portion having means for removing the laminate. this bag is designed to contain liquid and be self-supporting.

Other types of specialized packaging include: There is a bag that has been measured. An example of such a bag is U.S. Patent No. 4,890,439. (Smart et al.). The specification includes an address from the top center. An accessible lay-flat bag is shown. microwave oven Other packages used for cooking are disclosed in U.S. Pat. Specification No. 4937410 and Specification No. 4950859 (Anderson ) is disclosed. The packages disclosed in these specifications have a flat bottom with a wall extending upwardly from substantially the center of the bottom portion within the package. Allow access to the section. Bag disclosed in the above specification No. 4937410 Access to the inside of the lug is possible from the upright joint on the side of the wall. However, in the nokuragu disclosed in other specifications, the inside of the bag is Access to the department is possible. Their access is limited to filling product into the It merely allows successive removal of and and products. However, these None of these bags allow for controlled dispensing of product from within. . They only allow access to the cooked contents.

A pond-type bag suitable for microwave cooking is disclosed in US Pat. No. 435,846. Specification No. 6 (Stevenson), Specification No. 4904093 and Specification No. 50 No. 30190 (Woods et al.). These bags have two It is made from a wing-shaped pouch with an upright take-out part formed on one side. Ru. The extraction part is an opening that allows access to the interior and cannot be closed again. He has the ability to do it. This zipper allows Anderson's example Filling and unpacking the bag using the same simple method as shown in It can be carried out. This take-out part facilitates dispensing while adjusting the amount to be taken out. It's not designed to be done. The manufacturing process for the aforementioned Stephenson bag is , heat-fuse the appropriate parts of the process and side edges to form the gusset part at the bottom of the bag. It includes the process of putting on clothes.

The opening part without the gusset part constitutes the central neck part, and this This part becomes the extraction part.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS In the drawings, identical elements are designated with identical reference numbers.

FIG. 1 schematically shows the process and apparatus of the invention. continuously supplied A flexible web material 10 is processed into individual sachets 12. continuously supplied Preferably, the flexible web material IO is a single piece. However, multiple The webs are supplied and they are processed before the folding and forming process described below. It should be understood that these processes may also be combined into one. . If multiple webs are supplied, the width of each web is It is determined by which parts of the product, the pouch, are comprised. Like that Multiple webs can be continuously and reliably brought together by conventional means such as heat-sealing or adhesives. It is considered a body.

The flexible web material 10 is mounted on a roll 14 normally mounted on a spindle 16. It is preferable that the water be continuously supplied. The spindle 16 is for web feeding. Attached to the drive system in a conventional manner. In this case, if necessary, The spindle 16 is rotatably mounted with the roll 14. In other cases, The roll 14 is arranged to rotate freely on a spindle 16 and is Web material 10 is withdrawn from roll 14 when required by the apparatus to do so.

In still other cases, conventional roll braking mechanisms (not shown) or frictional brakes may be used. It is preferable to use a structure. These are applicable if the device is of an intermittent operating type. This is a known means for preventing rotation of the roll 14 during the idle period of the device. Ru. In these cases, a normal stop switch may be used to brake the rolls during equipment downtime. A switch mechanism (not shown) is used. When the roll 14 is driven, the following processing is performed. As in the case of the construction process, the operation timing of the driving means (not shown) and the braking means is mutually controlled appropriately.

First, the flexible web material 10 is applied to a tensioning mechanism 18 that applies tension. It is threaded through the space. The tension mechanism 18 includes a plurality of tension rollers 2 0. At least one of the tension rollers 20 is movably threaded. Supported in a conventional manner, this movable roller 20 is provided with biasing tension means. (not shown). Such adjustment (applying tension) This can be accomplished in any known manner, either mechanically, electrically, or pneumatically. can be done.

After passing through tension rollers 20, web material 10 passes through plow mechanism 22. do.

Plow mechanism 22 folds web material 10 into a generally W-shape. This W-shape is The side walls 24 and 26 are continuous at their bottoms by a bottom gusset 28. It is composed of. As mentioned above, multiple webs are folded into one A web may be configured. The plow mechanism 22 plows a specific triangular plate 30. The front part 31 of the plate 30 is cut and folded back, and a gusset is provided. Together with the blade 32, it forms a bottom gusset 28. The web material 10 is a plate 30 and is formed between the tip of the front part 31 and the set blade 32. It passes through a nip.

The gusset blade 32 has a pointed tip. This tip is attached to the web material with respect to the plate 30 by a predetermined length in the lateral direction so as to cross the moving direction of 10. It extends from the front portion 31 at a predetermined angle and forms a bottom gusset 28 . Gase The cut blade 32 is adjustably mounted to the device frame (not shown). Preferably, the depth of the bottom gusset 28 is adjustable. Preferred construction of the present invention In the process and equipment, the depth of the bottom gusset 28 is the width across the sidewalls 24.26. It is preferably about 1/2 of the direction dimension. This depth is relatively deep. it is conceivable that. The reason will be explained later. After passing through the plow mechanism 22, it is folded. The web material IO is processed using a creaser bar. ) 34. After passing through the crease server 34, the side wall 24 and the bottom gusset 28 and between the sidewall 26 and the bottom gusset 28. A fold is added which further divides the bottom gusset 28 into two parts 38.40. A groove 36 (see FIG. 2) is formed.

From this point onwards, several processing steps take place. Processing is folding All portions of the flexible web material 10 that are It refers to the molding process. Such a forming process involves forming each part of the web material IO. Connect or seal components to each other and do so before, during, or after sealing. This includes cutting the parts and all other forming steps mentioned above.

After the folded web material 10 passes through the crease server 34, the first forming hand The stage carries out the first processing step. In manufacturing the pouch 12 of the present invention, the first The first forming means is a sealing means. As shown in FIG. 2, the first forming means 42 is used to heat seal the gusset portion 40 to the lower portion 44 of the sidewall 26. Ru. The gusset portion 40 and the lower sidewall portion 44 form one gusset/sidewall combination. make up the minutes. The other gusset/side wall combination part includes the gusset part 38 and the lower side wall. 46. An advantageous advantage of the process and apparatus of the invention is that By forming means 1, only one gusset/side wall combination part is changed. At the point. In other words, a combined portion consisting of the gusset portion 40 and the side wall lower portion 44. However, by heat-sealing a part of the gusset part 40 to a part of the side wall lower part 44, change in appearance or substantially.

In order to perform the first spherical process on only one gusset/sidewall combination, two The molding process can be carried out on only one selected part. Preferably, they are separated from each other. Separate the two combined parts One method is to include a separation element 48 within the gusset 28, as shown in FIG. It is to insert. Separation element 48 is inserted along fold line 36 is preferred.

The use of such separation elements is optional and depends on the type of molding process and how It can be understood that this varies depending on how the molding process is controlled.

For example, in the heat fusing process, heat fusing parameters such as temperature and dwell Achieve the required heat fusion without escaping the necessary heat by controlling the . If the heat escapes, it will affect the other combined parts. Furthermore, such Whether a separating element is required depends on the material properties. Material properties include their It also includes the heat transfer properties of the outer surface and the number of layers to which heat can be transferred.

The first forming means 42 includes a reciprocating heat-sealing bar 4 having a protruding surface of a certain shape on its surface. It has 9. The operation of the heat sealing bar 49 is controlled and the operation of the gusset portion 40 is controlled. A portion is heat-sealed to a portion of the lower portion 44 of the side wall. The heat-sealing bar 49 connects the wire 51 to a heating element 50 connected to a power source (not shown) in a conventional manner. . When the heating element 50 is electrically heated, the temperature of the heat-sealing bar 49 increases during the heat-sealing process. The temperature rises to a temperature higher than that required for the process. Necessary to perform the heat fusion process The temperature will vary depending on the melting point of the web material 10 being used. illustrated The heat-sealing bar 49 is fixed to the drive link 52, and the drive link 52 is heat-sealed. The bar 49 is moved back and forth. Heat-sealing bar 49 during periods of rest between each intermittent operation of the device A protruding surface 54 contacts the outer surface of the lower sidewall portion 44 and the gusset The drive link 52 is normally aligned such that the outer surface of the portion 40 is in contact with the separation element 48. The timing is controlled by the law. Drives the drive link 52 and controls the timing. Such means of controlling are well known and are not an essential part of the invention. teenager Ostensibly, a center drive shaft is located within an intermittent-acting horizontal device; This controls each element of the forming station.

The separation element 48 allows the gusset portion 40 and the side wall to be separated by the first shaping means 42. The heat fusion process can be effectively performed only on the combined part consisting of the lower part 44. . Additionally, a support block 56 that reciprocates in synchronization with the heat-sealing bar 56 may be used. is also preferable.

A reciprocating support block 56 is connected to a drive link 58. driving link 58 is also driven and timed in the usual manner using a drive mechanism provided in the device. management is controlled. More specifically, the surface on which the protrusion of the heat-sealing bar 49 is provided 54 contacts the side wall lower portion 44, substantially simultaneously the support block A front surface 60 of 56 contacts the outer surface of lower sidewall portion 46 . as shown , such contact occurs when separation element 48 is located within gusset 28. Ru.

The surface 54 of the heat sealing bar 49 has a forwardly projecting protrusion, as shown in FIG. It has a surface 62. Surface 62 includes a gusset/sidewall combination (i.e., a gusset The shape of the seal formed by heat fusion on the bottom portion 40 and the lower side wall portion 44) is stipulate. In manufacturing pouches 12 according to the present invention, protruding surfaces 62 are contoured. The edge 64 defines the shape of the extraction portion. The first configuration as shown in Figure 1 The shape of the take-out portion 66 formed in each pouch 12 that has passed through the shaping means 42 Determined by 4. A continuous flexible web material 10 is advanced by means of feeding described below. Then, a portion of the combined portion consisting of the gusset portion 40 and the lower side wall portion 44 The heat-sealed portion 67 sequentially forms the extraction portion 66 . Removal part The shape of the portion 66 is equal to the shape of the protruding surface 62.

Referring again to FIG. 1, the following processing steps are performed in the second forming means 68. Ru. The second forming means 68 is also applied to only one gusset/sidewall combination. The molding process is carried out. According to the invention, the second shaping means 68 are the first shaping means 4 The same combined parts as in case 2 (that is, the gusset part 40 and the lower side wall part 44) Molding is performed. However, in the manufacture of other packages, a second molding process is required. Preferably, the step 68 performs the forming of the other mating part. Furthermore, intermittent In the case of an actuated device, the second shaping means 68 provide a pause between actuations of the device. It operates at different times and sequentially performs the forming process on each pouch.

According to the invention, as shown in FIG. Equipped with a cutting diamond 0 capable of cutting. The cutting diamond 0 has already been partially heat-sealed. The combined part consisting of the gusset part 40 and the side wall lower part 44 which have been rolled Used to remove a portion. In other words, each sachet is sealed by heat fusing. The removed portion 67 is removed by trimming. The cutting process using cutting diamond 0 is Preferably, this is done only once for each section 67 that is rolled. cutting diamond 0 can be reciprocated by any conventional means, and can be driven reciprocatingly by any conventional means, and The timing with the driving means of the device can be controlled so as to correspond to the operation of the feeding means described above. Wear. Unlike the first forming means 42 being driven by a normal drive link, the cutting device Ear 0 is reciprocated by an air cylinder 72, as shown in FIG. It is preferable that However, other similar mechanical, electrical, or fluid-based It is also conceivable to use a driving means such as the following. Air cylinder 72 is the frame of the device (not shown) and fixed to the frame of the device as shown. It is held in place by a bracket 73. Create air cylinder 72 A conventional sensor mechanism is used to control the timing of the cutting process. is used to detect whether the web material 10 is moving or stationary. This detection For example, by sensing the rotation of a center drive shaft (not shown) It is done. Then, the air cylinder is driven to perform cutting while the equipment is at rest. It will be done. In this case, the center drive shaft of the drive mechanism provided in the device using a microswitch (not shown) actuated by a cam (not shown). It is preferable that The cam opens or closes the microswitch, An air cylinder is operated during each rest period of the device.

In the cutting process, in order to separate both gusset/sidewall combination parts from each other, A separation plow 74 is inserted into the gussets 28 of the web material 10 and removes both gussets. ・So that the side wall combination parts are separated from each other and each is in a substantially vertical position. Forced upward from some resting position.

A perspective view of the separation plow 74 is shown in FIG. It is divided into a section 76, a central section 78, and a rear section 80. front part 76, central part 78, and rear portion 80 may be integrally formed or separate components. . The separating plow 74 may be hollow or solid, or a combination thereof. You can. Front 76 and rear 80 as shown in Figures 3.6 and 8 is preferably hollow and the central portion 78 is solid. Furthermore, the central portion 78 A flow path 81 is formed in the center portion 78, and a fluid is circulated through the flow path 81 to cool the central portion 78. Possible methods include cooling or heating.

Depending on the material and the requirements regarding the fusion temperature, the heat fusion process may generate too much heat. cooling is performed when necessary to offset excess heat. flow path 81 Manifolds, heat exchangers, pumps, compressors, etc. (not shown) as required. With appropriate connections, the central section 78 can be cooled or cooled using a fluid such as air, gas, or liquid. can be heated. In the present invention, cooled air is circulated in the flow path 81. to cool the central portion 78 and remove the flexible wafer folded during the cutting process described above. Preferably, the material 10 is cooled. To do this, a hollow front part 76 and The front part 76 or the rear part 80 is used as a manifold leading to the flow path 81. The hollow interior of either section 80 is hermetically connected to a source of cooling air (not shown).

Returning to FIG. 1, after the folded web material 10 has passed through the first forming means 42, The bottom gusset 28 is split by the front 76 of the separation plow 74 so that both gussets - The side wall combination parts are pushed apart from each other. folded web material When the material 10 reaches the center portion 78, both gusset/side wall combinations are cut. The separation is substantially uniform over a length sufficient for the treatment to occur. In other words , the length of the central portion 78 between the front portion 76 and the rear portion 80 is within that length. The length is such that the cutting diamond 0 can perform the cutting process. Rear 80 must be It should be noted that this is not necessary either. However, the web material 10 After passing 8, the rear 80 It is preferable to provide In the non-separated state, the gusset/side wall combination part is Take a substantially vertical posture in preparation for the subsequent process.

During the rest period between the operations of an intermittent-acting molding machine, the folding Once for each of the heat-sealed portions 67 arranged in order along the web material IO Preferably, the cutting step is performed.

One form of cutting out a desired shape from a material is the knife-like shape shown in FIG. The edge 92 is located near the downstream end of the cutting dia 0 in FIG. It has a cutting portion 94 extending to . The cut portion 94 is cut between the gusset portion 40 and the lower side wall. portion 44 between the gusset portion 40 and the side wall lower portion 44. from the fold line 36 to substantially the gusset fold line 36. knife edge The other part of 92 is divided into two parts 96 to form the extraction part. , each leading to a portion 98 forming an easy-to-open tab. for each cutting process The cutting diamond 0 is then cut into the folded web material 10 by an air cylinder 72. When driven, a part of the heat-sealed portion 67 formed by the first forming means 42 Trimmed and removed. And after that, there is a take-out tab with 100 easy-to-open tabs. parts are left behind. This is clearly shown in FIGS. 1 and 7. Furthermore, take out The entire portion 66 remains sealed by the joint 102. Joint part 10 2 is composed of the portion left after the cutting process of the heat-sealed portion 67. moreover, The ejection portion 66 extends into the easy-open tab 100. In a configuration like this Therefore, if the tab 100 is torn or cut at its recess 104, it will be removed. Portion 66 can be unsealed. In this way, each sachet 12 is easy to open. It has the following characteristics.

Instead of trimming a small piece from each pouch fabricated according to the present invention, the heat-sealed portion 67 It is understood that excess material may be excised as a strip, including a portion of the can. To do this, it is necessary to slightly change the shape of the knife edge 92. be. Specifically, without forming the cutting portion 94 extending in the transverse direction on the cutting diamond 0, The knife edge 92 is slightly extended along the length of the web material 10 to make each cut. At least a small portion of the edges of the cuts in the process overlap. Configure.

As previously mentioned, the knife edge 92 presses against the central portion 78 of the separation plow 74. When folded, the gusset portion 40 and lower sidewall portion 4 of the folded web material 10 Cut the combined part consisting of 4. In this way, it is used to cut the web material 10. The length of the knife-like edge 92 in the longitudinal direction is the length of the center portion 78 in the longitudinal direction. Must not exceed.

This is independent of whether the piece or strip of material is trimmed or not.

The cutting diamond 0 may be provided with two cutting portions forming the extraction portion. I can understand what you are saying. This is a complete knife-like piece with the shape of the extraction part. It is composed of two pipes, one end of which is continuous. And these taken together are twice the length of the cutting means forming one extraction section.

Such a cutting die is used once every two sachets of web material IO. Just turn it on. In this case, the central portion 78 must also be made twice as long. No. In a similar way, three or more extraction parts can be cut in one This may also be done using a cutting die. In that case, the cutting die must form the extraction part. To trim as many pouches in one operation as there are cutting means provided therein. Can be done. This technology performs the same multiple molding steps by one operation of the molding means. is suitable for all kinds of molding processes including the heat fusion process using the first molding means 42 described above. It can be used in the process.

Note that there may be cases where there is no need to perform the trimming process at all. First forming means 42 allows the take-out portion 66 to be easily molded as described above and to save a small amount of excess material. It is left as part of the bag. This means that there is no need for easy opening and removal of the part. It is further preferred if it consists of only a small amount of extra material. gusset The length from the fold line 36 of the combined portion consisting of the portion 40 and the lower side wall portion 44 is than that of the other combined portion consisting of the gusset portion 38 and the lower side wall portion 46. This reduces the amount of excess material. This means that the plow mechanism 2 This can be done by controlling the folding process according to 2.

As can be seen in Figure 1, once the cutting process is finished, the joint 102 seals the A take-out portion 66 having an easy-to-open tab 100 is completed. Then the first side The portion sealing means 106 performs a spot seal (heat sealing) midway between the extraction portions. (sole by fusion is preferred) process. Spot stickers are folded In the transverse direction of the web material 10, at a position where the material changes from four layers to two layers. It is done. This position corresponds to the gusset fold 36 between sidewalls 24 and 26. This is the position corresponding to the position of . The position where the 4th layer changes to the 2nd layer is prone to deterioration, so A spot seal portion 108 is provided at the position. It is necessary to perform spot sealing. Although not required, it is preferred to ensure a good side seal. spot sea If not, use side seals or equivalent means as described below. , a complete seal is provided on the sides.

Next, second side sealing means 110 are arranged. second side seal The means 110 extend from the bottom end of the folded web material 10 in the transverse direction to the top. Completely seal the sides to the ends. Each of the second side sealing steps It is carried out between the take-out part 66 and the take-out part 66, and the spot seal part 10 Preferably, this is done at a position including 8. The second side sealing means 110 is a pair of A sealer 112 is provided. The sealer 112 seals by heat fusion. It is preferable to do so.
