Abstract

PURPOSE:To prevent packages from being broken as well as increase a capacity of a case so as to save power and automate by a method wherein a specific number of products packaged in a square-bottom gusset bag are arranged and cased while summits are overlapped alternately in parallel in a direction that their top sealing parts are butted with each other. CONSTITUTION:After a packaged product 9 is put into a regulating box 8, a moving shaft 10 feeds the box 8 in this state from the position and stops at a position 10' along a guide groove 14 provided on a feeding plate 13. A cylinder 2 side rotates clockwise and a cylinder 3 side rotates counterclockwise by 90 deg. wherein on an opposite side plate provided on each arc operating shaft 12, by rotating a bottom plate by 90 deg. together, the packaged product 9 is exhausted from a regulating box 8'. Triangle parts of summits o the exhausted packaged products 9'' are engaged with each other together with heat sealing parts viewed planarly from upward near an arranging plate, and when viewed from front the parts are exhausted in an overlapping state. By repeating this operation, a specific number of packaged products are automatically cased on the arranging plate.

Description

[Detailed Description of the Invention] Summary of the Summary of the Invention The present invention relates to the production of lightweight and bulky products, such as individually wrapped Snaguku sweets, which are then delivered to retailers for provision to consumers (-in which case, a predetermined These products are packaged in large quantities and delivered in cardboard cases, etc., but the selling price of these products is low relative to their volume, and packaging materials and shipping costs account for a high proportion of the cost.In order to reduce this, packaging products and cases and This invention is related to improving the packing.

<Prior art> Foods such as snacks, which are preferred foods, are soft and palatable, and their consumption is increasing rapidly, but they are lightweight, bulky, and break easily. The sea bream is quantitatively weighed and packaged using a packaging machine, which is packed in a certain number of cardboard cases, etc., and delivered, but most of the packaging is made using UPX CP, polyethylene, or aluminum vapor deposited on these using a packaging machine that is easy to operate and handle. There are many cases in the form of columns, called pillow packaging, which are made using packaging materials made by appropriately combining and laminating packaging materials.

This packaging method uses low cost packaging materials and is easy to package, making it suitable for mass production.As mentioned above, a predetermined number of individually wrapped products are packaged together in a cardboard case and then shipped. Due to the shape of pillow packaging, there is inevitably a space between the parts that contact the case and between each bag, especially for products such as potato chips, which are wrapped individually in pillow bags to prevent them from breaking during the distribution process. In order to enclose extra C2 air in the product, a corrugated pole case or the like with a volume of 2,596 to 40 or more thicker than the net volume of the product is sometimes used.

Snacks and the like are originally inexpensive products that can be easily made by hand, and their consumption is large.For the above reasons, the packaging materials used are also cheaper compared to carton packaging, etc., but the product itself is damp (: weak and Since they are easily affected by ultraviolet rays, etc., most packaging materials are laminated with a combination of packaging materials that have their own characteristics to prevent this, depending on the product. As the volume of the cardboard cases, etc. that house these items increases, the ratio of packaging materials to the price of the snack items stored increases, and furthermore, even if as much as possible is loaded onto the vehicle during delivery, the items themselves are inexpensive. The proportion of shipping costs cannot be ignored, and since many of these products are in billow form, their shape easily deforms when external forces are applied to them when packed in cardboard cases, etc., and they cannot maintain a constant shape, making it difficult to accumulate them. This is done manually, and automation by machines is delayed.As mentioned above, the costs put pressure on overall profits, and in addition, the display of products at retail stores takes up a lot of space and is not efficient, considering the selling price. there were.

<Purpose of the Invention> This invention aims to reexamine the packaging form of light and bulky products such as snacks based on the conventional technique or method C2 mentioned above, and to improve the packaging method by hand when packing the space constant into cardboard cases etc. However, we have reconsidered this and created a device to handle these easily breakable products from the outside (minimize the force on the tripod to prevent breakage, improve the efficiency of storing the tripod in the case, save labor, automate the logistics, etc.) The aim is to provide an excellent method that also reduces costs.

Means and action for solving the above-mentioned problems In order to improve the above-mentioned problems of lightweight, bulky and easily breakable products such as snack foods, square-bottomed gusset bags are added to packaging bags made of flexible packaging film. Each time the packaging bag is sent, the product is put in.Excluding the top, the bottom and the four surrounding sides are surrounded by a grate regulating plate and bottom receiving plate of predetermined dimensions, and then the product is put in. It applies vibration within a range that does not damage the contents, reducing product volume and increasing filling efficiency.
After sealing the upper part with a method such as heat sealing,
Due to the configuration, it is impossible to achieve a filling efficiency of 100 or more, and a space of the size of the upper part C2 remains, but the shape of the upper part, when viewed from the side, is the upper part C; It is a square bottom gusset bag filled with a product that has a triangular shape and the overall height is the same as the inner dimensions of the aforementioned regulation plate at the height plus the height of the heat seal.

In this case, the square bottom gusset bag is made by filling and packaging the product and heat-sealing the top.The shape of the square bottom gusset bag is that the bottom receiving plate is removed from the bottom while the shape is maintained by the regulating plate. Lower the middle C2 and insert it.

There are various types of packaging machines, including vertical, horizontal, and high-speed and low-speed models.There are single-type packaging machines that pack one bag at a time, and twin-type packaging machines that pack two bags at the same time. The product is then packaged.

Recently, the highly efficient vertical twin type is often used, but in either case, the product is packaged in a packaging bag C, which is packed in a predetermined amount and then placed in a regulated box. The mutually packaged products are moved to a predetermined position C2 on the post-feeding plate with the tops slightly shifted in the front-back direction, so that the heat-sealed parts are vertical, and the triangular parts of the tops mentioned above are alternately parallel to the heat-sealed parts. The bags are taken out from the regulation box by knocking them down so that they overlap, and each time the two bags are placed in one set on the alignment plate (after the predetermined number of sets have been arranged),
If it is a stage, it will be in that state, and if it is 2 to n stages, it will be the predetermined plurality of stages! M: Initially, the products lined up on the stacking plate waiting directly below the alignment plate are received by the support plate, the alignment plate is moved in that direction, all packaged products are transferred to the stacking plate, and the stacking plate is lowered by one level. After that, the alignment plate is returned to the old position and the next alignment begins, and this is repeated until the predetermined number of stages have been accumulated on the accumulation plate. If products are to be packaged in cases using, for example, camel round casers, etc., as has been done in the past, one sheet of corrugated cardboard prepared in a magazine is fed out and placed in a predetermined position. While holding and guiding both sides with guide plates, feed the packaged products to the predetermined position C- of the corrugated cardboard sheet mentioned above with a guide plate. Caser operation C: Pack the case further.

At this time, the shape of the part where the product is mainly contained inside the packaging container, which is formed into a set of square bottoms, is surrounded by a regulating plate, and the shape is measured, filled, packed, aligned, stacked, and then sent to a predetermined position on the corrugated board sheet, so each step However, due to the sudden force applied from the outside, care has been taken not to damage the product, and the triangular part that forms the upper part will be slightly deformed at the final stage of packing into the case, but packaging material 4: If a laminated film or the like is used, the content product will not be fully filled in that part C2, and if anything, the content product will not be fully filled in that part C2, and the product content will be aligned and stacked with a small margin in the flexible part, and the content product will be mutually stacked together with the contained packaging bag. (; Also, each inner surface of the case () will be filled with a cardboard case, etc., which fits well and has high volumetric efficiency.

This is due to the deformation that occurs during handling when packaging products in the conventionally frequently used billow-type packaging into cardboard cases. The parts that naturally come into contact with each other or the inside of the case due to the shape of the packaged products (:
In order to greatly reduce the drop in volumetric efficiency due to the extra space that had been generated, and to automate the packing of cardboard cases, etc., we have also adopted a method that can automate the packing of cardboard cases. The method of opening and displaying the boxes also incorporates the new rail axis, and takes technical measures that allow these operations to be carried out more easily in a narrow space.

<Embodiment> Next, an embodiment of the present invention will be described as follows.

Type R of packaging methods for square bottom gusset bags have been developed, but in this example, method C2 is used, which is carried out using a packaging machine that carries out packaging by attaching an attachment for square bottom gusset bags (vertical billow packaging machine). Figure 1 omits the part before the bag making part of the packaging machine, and the relevant parts after that are shown in Figure 2 C.
2 schematically shows the whole of this embodiment, and the arrows in the drawings schematically indicate the operations of the device parts. Cylinder 2 of a twin-type packaging machine with the bag dimensions set as B1 total height C, and the cylinder 3 is also shaped like a rectangular cylinder C2 on the four circumferences, and the bottom is heat-sealed, and the outside of each side is colored. Inside a box-shaped frame surrounded by four regulating plates 4 supported by a part of the mounting machine and whose bottom is supported by a bottom receiving plate 5, insert the gusseted bag C2 and measure a predetermined amount into it. After putting the product into the bag and vibrating the regulating plate 4 and the bottom support plate 5 together while taking care not to break the product, the filling efficiency is sufficiently increased and the product settles inside the bag. A gusset tucker 6 is used to form a square bottom gusset bag that will be the bottom of the next bag together with the top seal of the bag, and a heat sealer 7 is applied.
At the same time, a cutter (not shown) installed horizontally in the heat sealer 7 cuts the heat-sealed portion at the center to complete the packaging.

Next, the C2 regulation plates 4 are moved back slightly from their initial positions (the Mitaka receiving plate 5 is also rapidly retracted in the direction of the arrow), and the middle C2 of the regulation box 8, which is waiting at the lower part of the C2, is placed in the round packaging described above. Insert the completed packaged product 9.

The regulation box 8 has its upper part expanded slightly outward so that the packaged product can be smoothly inserted into it, and is held by a plate supported by the transition shaft 10 and moved in an arc. Bearing plate with shaft 12 not shown: It is mounted with a shaft support, and each regulating box, cylinder 2 of box 8
On the side, the side surface of the cylinder 3 side and the L-shaped C bottom plate forming the bottom part are integrated, and the joint thereof is attached to the arc movement shaft 12 which is supported by the bearing provided on the plate 11 mentioned above, and the opposite side The side surfaces and the surfaces forming the front and rear regulation boxes 8 are fixed to the plate 11C in a U-shape.

In addition, the regulation box 8 on the cylinder 3 side is integrated with the side surface on the cylinder 2 side and the L-shaped C bottom plate, and the joint part is attached to the circular motion shaft 12 that is supported by a bearing provided on the plate 11, and the side surface on the opposite side The surfaces forming the front and rear regulation boxes 8 are fixed to the plate 11 in a U-shape, and the cylinder "-"
The 2 side and the cylinder 5 side are installed symmetrically.

This mutual regulation box 8.81: Each packaged product 9
．． When 9 is finished being fed, in that state, 10 is immediately transferred to the transfer shaft 1 from that position to the guide groove 1 stepped on the feed plate 13 along 14 to the positions 10' and 10'.
The 2 side moves in the direction of cylinder 3 by a distance shown by the double arrow in Figure 1C, reaches += 10' and stops, and also moves toward cylinder 3.
The side moves along the direction of the cylinder 2 along with the direction of the alignment plate 15 C2 arrow E1 = the distance indicated by the arrow Fε22 The distance also moves along the guide $14 stepped on the feed plate 13 and stops at the 10' position (: .

At that point, the circular arc movement axis 1a12 on the saw side is engaged with the clutches 16, 16 (:) which are set in advance at that position, and the cylinder 21II is clockwise; the cylinder 3 side is a 90 degree arc counterclockwise each arcuate axis of motion 12
, 121 = Attachment: Rotate both the opposing side plates and bottom plate by 90 degrees. From C2, packaged product 9.9 is 9',
The liquid is discharged from the regulation boxes 8' and 8' as shown in the figure 9''.

At this time, the transition shaft 10 on the cylinder 2 side is linearly displaced C2 in the direction of the cylinder 3, but the cylinder 3 is displaced at the same time.
The side transition axis is aligned with the alignment plate 1 shown by arrow F as described above.
It moves a distance of arrow F + 22 in the direction that combines the line segments of arrow E in five directions and stops, so the discharged packaged product 9'' is closer to the alignment plate 15 than the packaged product 9' discharged from the cylinder 2111. Viewed from the top, the top part has triangular parts together with the heat seal part,
When viewed from the front, the parts are discharged in an overlapping state.

Ru.

At the same time (37 packaged products 9', 19 are the width dimensions of the products) Approach the position shown by the solid line in FIG. 1, which roughly coincides with B, and sandwich the packaged products 9', v' between the comb-shaped parts attached to the tips thereof.In that state, the top of the feeding plate 13 is shown by the imaginary line. At the same time, the support arm 20 is moved from below to the alignment plate 15 at a position slightly in front of the position fed between the respective lofts forming the comb-like shape of the feed arm 18. Send play) 151”
:The feed arm 1 rises from the provided long arm (not shown).
8 on the alignment plate 15 (: Sent packaged goods 9'
, 9'', the feed arm 18 is held between the comb-like holding parts by the same comb-like holding part, the sending arm 18 returns to its old position, and the pick-up arm 19 is held together with the same comb-like holding part. (: After rising and preventing the packaged product sent in the first time from falling, the support arm (not shown) supports the support plate 2142 supported by C2, and then returns to the old position ε2, °
Each time a product is packaged, the above-described two-step operation is repeated, and the packaged products are placed on the alignment plate 15, 12 bags in this embodiment.
Assuming that the predetermined number of 1 dozen is to be automatically packed into a cardboard case that is arranged in two tiers as shown in Fig. 3C, the packaged products are then arranged in one tier. Directly below the alignment plate 15, there is a stacking plate 23 supported on the C2 lifting shaft 22. Cardboard sheet 2 prepared by
It is surrounded in three directions by a support plate 21 for preventing the aligned products from falling over, and a feed arm 18 for feeding the products into the alignment section. Align plate 1 in condition
5 is moved backward C2 in the direction shown by arrow G, and the products arranged in C2 are transferred onto the stacking plate 23, and when finished, the stacking grate 23 is raised to the height of one level of the products on the lifting shaft 22i. 2, the alignment plate 15 returns to its old position, and the feed arm 18 and the double support plate 21 return to their original positions to receive the packaged products sent in for alignment in the first time, and are placed in the next stack. Be prepared.

Since this embodiment is an example of stacking in two stages, the first stage of packaged products is transferred onto the stacking plate 23, and then a predetermined number of packaged products are placed on the alignment grate 15, which has returned to the previous 1t position above the stacking plate 23. When the alignment is completed, the alignment plate 15 is moved back in the direction of the inn arrow force as described above while enclosing the three directions to prevent it from collapsing. Transfer the products and stack them on two tiers.

During this time (: The auto caser 26 that packs the blanks into cardboard cases is often of the rough ground type, etc., and the case magazine 27 is supplied with a fried blank cardboard sheet 29, which is then placed one sheet at a predetermined position. (:
The sheet is fed by the sheet feeding belt 28 or the like and kept on standby, and as mentioned above, the sheet is placed on the stacking plate 26 in this embodiment.
2 stacks of 2 bags ε 2 stacked 1 case worth of packaged products are placed in a predetermined position above them, and when arranging them, leave a little space between each packaged product so that the operation can be done quickly and easily. First of all, the products placed in I row on the accumulation plate 23 are sent to the pukshlot 32C; The opposite side of the feeding guide grate 25 is surrounded in three directions by the collecting part guide 31, and the upper part i: The loaded 12 bags of packaged products are also surrounded in three directions by the collecting part puksha 30, and the lower part is surrounded by the collecting part guide 31. Alignment part pusher 24
Push out the upper tier and feed it to a predetermined position of the tiered pole sheet 29 that is on standby as described above. Prior to this operation, the accumulated product regulation plate 33,! +4 are aligned, the stacking section direction C2 is moved close to each other, and the accumulated products sent out by both pushers 30 and 24 are held across the two directions, and then pushed to the pusher 3 at a predetermined position on the C two-tiered pole sheet 29 using 24. During shipping, the distance between each packaged product is narrowed so that it has the specified dimensions when viewed from the top when packed in a two-corrugated cardboard case.

By the above operation, the cardboard sheet 29 is fitted to a predetermined position.
”: When the products accumulated according to the specified size are sent, the auto caser 26 returns to the old position 24 to both pushers 3.
For example, if this is a lug ground method, the part on which the accumulated products are placed is lowered from that position together with the corrugated sheet 29, and when the corrugated sheet 29 is fed into the fixed position, a hole (not shown) is moved. Adhesive is applied to the necessary places using a melt applicator, etc., and as the corrugated cardboard packing operation progresses, it surrounds the outer periphery and is ejected from the applied adhesive C2, and is transferred to the next process C2, which is normally carried out automatically. Cases are packed, and at that time, the accumulated product regulating plate 34 is temporarily retracted, for example, to the upper part, so as not to interfere with these operations, and then returned to its old position to prepare for the next feeding.

(; Prepare.

As mentioned above, the above-mentioned operation is repeated every time a product is individually wrapped by the packaging machine, and in this embodiment, as described above, 1 dome and 12 bags are stacked in two stages and are packaged in an integrated manner using auto caser C2. There are limits to the number of packaged products that can be arranged in one tier, and the number of stacks that can be stacked in one tier. It is also possible to have multiple stages.

Furthermore, for this purpose, the sheet C2 of the cardboard case for C binary use is placed at the position shown by the two-dot chain line H in FIG.
: Cut a perforation or a cut tape on the side part, and also cut it into a square shape, make it removable, and open it. In this case, separate this two-dot chain line H and move the point J to J'4= to remove the overcamel part of the packaged product housed in the cardboard case, and then
: From the 57 points at the bottom of one side shown as the base point, J” at the top.
Turn clockwise to point C2, and then move the remaining part shown in 36 from point L to point M counterclockwise to point N. Once the bales are cut and removed, the cut cardboard boxes shown in Figure 4 are stored in a shape that can be displayed at a retail store.
Furthermore, Fig. 5 shows an example of a case where a large quantity of items are displayed at a retail store, and one stage is placed on the display stand 37 in the state before each of the above-mentioned parts is captured, and the upper two stages hold two items. Show the product inside by cutting only the part surrounded by the chain line I, and then divide the 36th part on one side of C2 at the position shown by the two-point chain barrier H, which is slightly higher than the total height of the product. The remaining halves 35 are shown in two rows arranged in two rows. The triangular part at the top of the bag is alternately tagged with the seal part, and the surplus space is minimized to minimize the overall volume. By making the entire height of one side slightly higher, even if the remaining part is placed on top of the bag, the shape of the bag will not be damaged. When the packaged product is packed inside a cardboard box, there is a deformation in the part C2 where the square bottom gassect bags overlap each other, but as mentioned above, the two bags are opened so that the bottom of each bag is facing down. If you divide it exactly as shown and place it in a case, it will naturally recover to almost the same shape as when it was originally packaged, and it will have a well-defined shape.

C: Recovers and becomes well-defined.

As mentioned above, we have explained the method of automating case packing of products such as snacks, which was extremely difficult in the past, but the packaging speed of packaging machines will gradually be required to increase in speed, and as this progresses, it will be necessary to align and accumulate packaged products. , there is a waiting time during operations such as feeding to the autocaser, and it may become impossible to perform the rhythmic C2 operation, so there is a limit to speeding up the process, but this can be resolved by providing a buffer in the middle of each part of the process. Become efficient.

<Effects of the Invention> According to the present invention, a predetermined number of cardboard boxes can be used to deliver a pillow-type product, which is conventionally the most commonly used packaging method for lightweight and bulky products, to the consumer after the packaging is completed. The product is delivered in two cases, etc., and the packaging material of the round-wrapped product is also the price of the product. Because of their shape, the relationship between them (;
Furthermore, an inevitable G2 space was created inside the case, resulting in poor storage efficiency.

In addition, even if attempts were made to mechanize the process of packing into containers such as cardboard, the shape of the packaged products is soft and the stability during accumulation ε: Since it takes two people, automation has not progressed and this has been done manually. Filling and packaging are performed within a frame of a predetermined size in a way that increases filling efficiency, and the subsequent alignment, accumulation, and transportation do not involve adding local carbon chips, making it possible to use pillow packaging when filling cases manually. When grasping the product, avoid movements that could damage the product.
When arranging and stacking cardboard cases, etc., to increase the storage efficiency as mentioned above, the triangular parts at the top are alternately overlapped in parallel. In addition, the inner side of the case is in a state where the entire surface C is in contact with C2, and the operation of each part is mechanized and conventionally done using an auto caser such as a ground caser. Packing 1: Saves more labor, reduces the packaging film area and the case itself by increasing its storage efficiency, reducing costs, and 2: Reducing logistics costs during delivery 6: Also contributes, etc. It has excellent effects.

Furthermore, if you attach perforations or cut tape to predetermined positions on the cardboard sheet to be used, the case can be divided and opened using this. Even when displayed, the packaged products, which had been packed in two cases that were a bit cramped, over time regained their shape close to that immediately after packaging, and without any loss of product value, they can be stored in separate cases. There is no problem even if you take out %ε2 and arrange it on display shelf C, and especially in the current situation where the variety of products is increasing, it has a great effect such as being able to increase the number of products displayed in a small space.
