Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box packaging method for automatically packing a product in which foods such as potato chips, popcorn, beans, and chocolate are packaged or boxed into an exterior box such as a cardboard case or a dozen box. A method and a packaging device.

[0002]

2. Description of the Related Art As an example of the above conventional packing device, there is a device according to the application of International Application No. PCT / JP94 / OO662. This device is shown in FIGS. 24 (a), (e), (f).
Products such as the bag-filled product 1 and the boxed products 1a and 1b shown in FIG. In FIG. 24A, the bag-filled product 1 conveyed by the introduction conveyor 4
Are placed one by one in a gap portion 6 formed by a large number of fins 5 provided on the transfer surface of the aligning conveyor 3, and are lined up in a row while standing on the belt surface of the aligning conveyor 3. Line up.

Next, as shown in FIG. 24 (a), when a predetermined number of, for example, five bag-filled products 1 are aligned on the alignment conveyor 3, slits 12 are provided for avoiding interference with the fins 5. The pushing plate 11 pushing out pushes the bag-filled product 1 on the alignment conveyor 3, and supplies the bag-filled product 1 to the openable / closable damper plate 63 via the U-shaped relay plate 10. That is, the push-out plate 11 slides on the aligning conveyor 3 in a direction orthogonal to the conveyer 3, thereby pushing out the five bag-filled products 1 on the conveyer 3 onto the relay plate 10, and then further repeating the relay. The five bagged products 1 on the plate 10 are pushed forward by the following five bagged products 1 to move the bagged products 1 onto the damper plate 63 (see FIG. 24 (b)).

In this way, when the push plate 11 pushes the bag-filled product 1 to a predetermined position on the damper plate 63, the push-out plate 11 interferes with the next bag-filled product 1 that is being aligned on the alignment conveyor 3. In order not to do so, the upper side of the alignment conveyor 3 is slid back in the direction opposite to the pushing direction and returns, and waits at the position shown in FIG. 24 (a) until the start of the next pushing operation.

Next, as shown in FIG. 24 (b), the bag-filled products 1 extruded on the damper plate 63 in an upright state are sandwiched by the pair of holding plates 30 from the front and back of the aligned bag-filled products 1. Is retained. In addition, for example, since the contents of the bag-filled product 1 are easily broken, the holding force of the holding plate 30 cannot be increased so much.
In some cases, the bagging product 1 cannot be held only by the sandwiching force of the holding plate 30. Therefore, in consideration of such a case, as shown in FIGS. 25A and 25B, a pantograph mechanism 41 is provided between these two holding plates 30, and a large number of pantograph mechanisms 41 are provided. The gripping roller 47 is configured to pinch and hold the upper end of each bag-filled product 1.

Next, as shown in FIG. 24 (b), after holding the bag-filled product 1 by the pressing force of the holding plate 30 and the pantograph mechanism 41, the damper plate 63 is changed from the closed state to the open state, The holding plate 30 and the pantograph mechanism 41 that hold the bag-filled product 1 are moved downward and the bag-filled product 1 is inserted into the cardboard case (exterior box) 2 waiting at the lower position. The cardboard case 2 is conveyed by a roller conveyor (not shown) and stands by at a predetermined waiting position shown in FIG. 24 (c). FIG.
Reference numeral 2a shown in FIG. 4 (c) is a flap of the cardboard case 2.

Then, after the bag-filled product 1 is inserted into the corrugated cardboard case 2 while the bag-filled product 1 is held by the holding plate 30, the pair of holding plates 30 are driven in a direction in which they spread out. Release the pressing force against.
At this time, the pantograph mechanism 41 attached to the holding plate 30 is also changed from the shortened state shown in FIG.
The extended state shown in FIG. 5 (a) is released, and the baggage 1 is released from the grip. In this way, the bag-filled product 1 is stored in the cardboard case 2 (see FIG. 24 (c)).

Then, as shown in FIG. 24 (d),
The pair of holding plates 30 is raised to the upper position to drive the damper plate 63 from the open state to the closed state. In this way, returning to the original state shown in FIG. 24A, one cycle of the storage operation of the bagged product 1 is completed, and thereafter, the above cycle is automatically repeated to perform the boxing operation.

[0009]

By the way, in the case of a product whose contents are likely to be damaged, such as a snack food, when the product is filled in a bag (the bag of the bagging product 1), the contents are damaged. In order to prevent this, air or other gas is filled together with the contents. In this case, even if the bag itself is flexible, the bag is inflated by the internal pressure of air or gas, so that the bag is sandwiched by the holding plates 30 and the upper part of the bag stands. . Therefore, the bag-filled product 1 supplied on the damper plate 63
The upper end of each of them can be reliably moved between the gripping rollers 47 provided in the pantograph mechanism 41,
As a result, the gripping roller 47 can reliably pinch and hold the upper end portion of each bag-filled product 1. As a result, the contents are likely to be damaged, and thus the bag 1
Even when it is not possible to strongly pinch the bag, the holding plate 30 and the pantograph mechanism 41 can reliably hold the bagged product 1, whereby the bagged product 1 can be transported and stored in the outer box 2. You can

However, when beans, candy, chocolate, etc. having a relatively large specific gravity are filled in the bag, the contents of these bags collect at the bottom of the bag, and even when the side surface of the bag is sandwiched by the holding plate 30, the upper end of the bag is May fall sideways. In this way, the upper end of the bag is laid sideways because the contents collected at the bottom of the bag raise the bridge, and this bridge prevents the bag from being narrowed by the holding plate 30. This is because the internal pressure of gas such as air cannot be increased. In addition, when the bag is packed in a box in a standing state, the upper end of the bag is likely to fall sideways.

Therefore, when the bagged product 1 filled with the contents having a relatively large specific gravity is boxed by using the conventional boxing apparatus or method shown in FIG. 24, the holding plate is shown as shown in FIG. 24 (c). Since the upper end portion of the bagged product 1 is laid sideways when the bagged product 1 is sandwiched by 30, the upper ends of the bagged product 1 are provided between the gripping rollers 47 provided in the pantograph mechanism 41. Therefore, when the damper plate 63 is opened, of the bag-filled products 1 sandwiched by the holding plates 30, first, the bag-filled product 1 in the central portion falls off from the holding plate 30, Next, all the remaining baggings 1 may be dropped. That is,
The conventional boxing device described above has a problem in that the cardboard case 2 cannot be surely filled with the bag-filled product 1 filled with contents having a relatively large specific gravity.

By storing the bag-filled products 1 in the corrugated cardboard case 2 without any gap (tight state), the aligned condition of the bag-filled products 1 in the cardboard case 2 may be disturbed during transportation. It is known that the contents can be prevented from being damaged.

However, in the above-described conventional apparatus or method, as shown in FIG. 24 (d), the holding plate 30 is placed after the bag-filled product 1 is positioned in the cardboard case 2 in a tight state.
When pulling out the cardboard case 2, hold plate 3
There is a problem that the bagging product 1 also rises with the increase of 0 and spills out of the cardboard case 2. When the holding plate 30 is pulled out from the cardboard case 2, the distance between the pair of holding plates 30 is slightly widened to reduce the contact pressure with the bagged product 1. Since it is intended to be stored in a tight state, the contact pressure cannot be kept below a certain value, and therefore the above-mentioned problem that the bag-filled product 1 spills out cannot be solved.

Further, the holding plate 30 is supported by an expanding / contracting device which drives in a direction of expanding / contracting the mutual space and an elevating device which elevates / lowers the holding plate 30. Therefore, the total moving distance of the holding plate 30 is The total distance of the expansion / contraction distance and the ascending / descending distance results in a relatively long distance. Moreover, since it is also necessary to accurately position the moving ends on both sides of such a relatively long distance, extremely high accuracy is required for assembling the holding plate 30, the expansion / contraction device, and the elevating / lowering device. There is a problem that the cost is high.

According to the present invention, a product filled with any content from a content having a relatively small specific gravity to a content having a relatively large specific gravity can be neatly aligned and reliably boxed,
Another object of the present invention is to provide a boxing method and a boxing apparatus that can reduce the assembly cost.

[0030]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a box packing method and box packing apparatus according to the present invention will be described with reference to the drawings. FIG.
2 (a) and 2 (b) and FIGS. 2 (a) and 2 (b) are schematic diagrams for generally explaining the boxing process which is a feature of the present invention. 1 shown in each figure is a bag-filled product. The box packing method and box packing apparatus according to this embodiment are shown in FIG.
As shown in (b), the bag-filled product 1 is packed in a cardboard case (hereinafter referred to as an outer box) 2 with the bottom of the bag standing down. According to this boxing method and boxing device, for example, as shown in FIG.
The boxed products 1a and 1b shown in (e) and (f) can also be packaged in the outer box 2. In the figure, s is a snack food or a dry food. The bag-filled product 1 is inserted inside the box-filled product 1b.

In FIG. 1, 3 is an alignment conveyor,
The introduction conveyor 4 is connected to the alignment conveyor 3, and the bagging product 1 is transferred to the alignment conveyor 3 by the introduction conveyor (supply means) 4. That is, the bag-filled product 1 conveyed by the introduction conveyor 4 is formed by a large number of fins 5 (the fins are partitioning means described in the claims) 5 provided on the transfer surface of the alignment conveyor 3. One by one is sequentially supplied to each of the gap portions 6 thus formed, and moreover, they are loaded at right angles to the transfer surface of the introducing conveyor 4, that is, in an upright state. Incidentally, the alignment conveyor 3 is drive-controlled by the conveyor chain servomotor 8 and its control device so as to perform an intermittent motion, and the intermittent motion is caused by the introduction conveyor 4 as shown in FIG. One bagging product 1 that has been transported is one
It is set so as to be loaded in one gap portion 6.

Next, as shown in FIG. 1A, for example, 5
When a predetermined number of bag-filled items 1 are loaded and aligned in each of the five gap portions 6 between the fins 5 of the alignment conveyor 3, the push-out plate 11 provided with slits 12 for avoiding interference with the fins 5 (Picking-out means according to claim 7) pushes out the five bag-filled products 1 aligned on the alignment conveyor 3, which will be described later via the relay plate 10 having a U-shaped cross section shown in FIG. It is supplied onto the damper plate 7 that can be opened and closed (see FIG. 1B). That is, the extrusion plate 1
1 can slide on the aligning conveyor 3 in the horizontal direction orthogonal to the aligning conveyor 3 by the linear motion mechanisms 14 and 15 which will be described later, whereby the bag-filled product 1 on the aligning conveyor 3 is transferred to the intermediate plate 10. After being pushed out, the five bags 1 in the first row on the intermediate plate 10 are further pushed forward by the five bags 1 in the second row, and the bags 5 in two rows each are formed. The padding 1 is moved onto the damper plate 7 in the holding position.

This operation will be described in more detail. As an example, the pushing plate 11 is slid from the original position shown in FIG. 1 (a) by a stroke twice the width of the bagging product 1 to move the five bags 1 of the first row of the filling plate 10 into the intermediate plate 10. Move it to the back. Next, the width of the bag-filled product 1 is slid from the original position, and the five bag-filled products 1 in the second row are moved to the inlet of the intermediate plate 10. In this state, the intermediate plate 10
Five pieces of the two-row bagging product 1 are placed on the top. If the next bag-filled product 1 is not placed on the alignment conveyor 3,
By sliding the packed product 1 from the original position by a stroke that is three times the width of the packed product 1, the two packed bags 1 of five pieces can be moved onto the damper plate 7. However, when the next five bag-filled products 1 are placed on the alignment conveyor 3, slide by the stroke of twice the width of the bag-filled product 1 from the original position, and the five bags in the third row With the bag-filled product 1 of FIG. 1, the front two rows of bag-filled products 1 can be moved onto the damper plate 7 (see FIG. 1B).

The slide operation for pushing out the bag-filled product 1 by the push-out plate 1 is controlled so as to be performed when the aligning conveyor 3 is temporarily stopped by the intermittent motion. By the way, the operation of the extrusion plate 11 is
The present invention is not limited to the above, and the operation stroke and the like can be freely adjusted according to the width of the bag-filled product 1, the number of rows to be stored in the outer box 2, and the like.

As described above, the extrusion plate 11
However, when the bag-filled product 1 is pushed out to a predetermined position on the damper plate 7, the push-out plate 11 does not interfere with the next bag-filled product 1 which is aligned above the alignment conveyor 3 on the alignment conveyor 3. It slides in the direction opposite to the pushing direction, returns to the original position, and stands by until the start of the next pushing operation (see FIG. 1A).

By the way, as shown in FIG. 1 (b), two columns of five pieces (a total of one row) are extruded on the damper plate 7 in an upright state.
The (0 pieces) bag-filled product 1 is sandwiched from the left and right sides by holding plates 9 and 9 which are vertically provided at both sides in the alignment direction of the bag-filled product 1, and the holding plates 9 and 9 are pressed by the holding plates 9 and 9. Hold (hold state). That is, when a predetermined number of 10 bag-filled items 1 are aligned on the damper plate 7,
The holding plates 9 and 9 press the bag-filled product 1 from both sides and hold it. In this held state, the suction box 13 provided above the damper plate 7 descends so that the lower surface of the suction box 13 comes into contact with the upper portion of the bagging product 1 and the suction force of the suction box 13 causes the bagging product to be packed. 1
(In particular, the bagged product 1 located at the center of the aligned bagged products 1) is sucked upward. Of course, it is also possible to adopt a configuration in which the upper portions of all 10 bag-filled products 1 are sucked. The suction box 13 can prevent the bag-filled product 1 sandwiched by the holding plates 9 from slipping off from the holding plate 9. That is, for example, when the specific gravity of the contents (for example, chocolate) of the bagged product 1 is relatively large, or when the weight of the contents is heavy, the bagged product 1
When the holding plates 9 and 9 are sandwiched and held by the holding plates 9 and 9 in a relatively small number of rows, such as one row, and the holding plates 9 and 9 cannot be pinched so strongly that the contents are easily damaged, bagging is performed. When the size of the product 1 is relatively small, the bagged product 1 easily slips off from the holding plates 9, 9, but the bagged product 1 is held by the suction force of the suction box 13.
Can be prevented from slipping off the holding plates 9, 9. Therefore, the suction box 13 can be omitted when the above-mentioned cases do not apply, such as when the specific gravity of the contents of the bagged product 1 is relatively small.

When the bagging product is held by the holding plate 9 and the suction box 13 as described above,
As shown in (a) and (b), the two damper plates 7 located below the bagged product 1 are driven from the closed state (state of the holding position) to the open state (state of the non-holding position). . Then, the outer box 2 waiting on the outer box elevating conveyor 17 described below is lifted by the air cylinder 98 and moved to a position that covers the holding plates 9 (see FIG. 2A). The outer box 2 is conveyed by a carry-in conveyor 96, which will be described later, and stands by at a predetermined position on the elevating conveyor 17. 2a in the figure is a flap of the outer box 2.

Next, the holding plates 9, 9 located inside the outer box 2 are slightly moved by the expansion / contraction device 16 in the expanding direction to release the force for pinching the bag-filled product 1 (non-holding state). After that, the suction box 13 descends to forcibly push the ten bagged products 1 into the bottom of the outer box 2, and then the outer box 2 descends, whereby the bagged products 1
Can be separated from the holding plates 9, 9. Before the suction box 13 is separated from the upper portion of the bag-filled product 1, the switching valve 19 described later is activated to release the suction force of the suction box 13 and the suction box 13 is separated from the upper portion of the bag-filled product 1. Therefore, 1
Zero bagged items 1 can be stored in the outer box 2.

Thus, the outer box 2 in which the bagging product 1 is stored
Is lowered to the original lowered position (see FIG. 2B) and discharged to a predetermined discharge position, the next outer box 2 is supplied to the position below the damper plate 7, and the suction box 13
Returns to the original raised position, the damper plate 7 in the open state returns to the closed state, and the state shown in FIG. This completes one cycle of the boxing work of the bagged product 1. Thereafter, the box packing operation can be automatically repeated by sequentially repeating the above steps. 4A to 4D are diagrams showing the order of operations of the damper plate 7 and the exterior box 2.

Next, the introducing conveyor 4, the aligning conveyor 3,
Push plate 11 and its operating mechanism, holding plate 9
And its operating mechanism, the suction box 13 and its operating mechanism, a device for raising and lowering the exterior box 2, and an opening / closing mechanism of the damper plate 7 will be described in order.

[Introduction Conveyor 4 and Alignment Conveyor 3] FIG.
The introduction conveyor 4 shown in FIG. 2 is a belt conveyor made of synthetic rubber, and sequentially conveys the bag-filled products 1 that are supplied from the vertical pillow packaging machine or the like provided in the preceding stage at substantially constant intervals at a high speed in the subsequent stage. It is supplied to the provided alignment conveyor 3. However, the interval between the bag-filled products 1 may vary depending on the operating conditions of the packaging machine in the previous process. Therefore, as shown in FIG. 7, a sensor 20 for detecting the bagged product 1 is provided at the entrance of the alignment conveyor 3, and the drive provided in the alignment conveyor 3 based on the detection signal of the sensor 20. The servo motor 8 for use is configured to start at an appropriate timing.

The aligning conveyor 3 shown in FIG. 7 is equipped with a plastic slat band chain 21, and a large number of fins 5 are provided on the flat conveying surface of this slat band chain 21. The chain 21 is made of plastic to reduce its weight. The alignment conveyor 3 is driven by a servo motor 8 to perform high-speed intermittent traveling. As shown in FIG. 7, the fin 5 is an inverted L-shaped metal plate, and a gap portion 6 is formed in a gap defined by the adjacent fins 5. The gap portion 6 is formed slightly wider than the thickness of the bag-filled product 1. That is, the bag-filled product 1 can be held in a slightly loose state in the upright state.
Further, the fins 5 spread radially at the entrance of the alignment conveyor 3 (at the position of the driven sprocket 22) to form a loading port 23 for the bag-filled product 1.
The bag-filled product 1 conveyed by is slipped. Further, a drive sprocket 25 rotatably supported by a drive shaft 26 is provided at the left end portion of the alignment conveyor 3 shown in FIG. 7, and the drive sprocket 25 is connected to a servo motor via a timing belt 27. 8
It is connected to the rotating shaft of.

The bag-filled product 1 conveyed by the introduction conveyor 4 is conveyed with its bottom portion facing forward, and therefore,
The bag-filled products 1 supplied one by one to the gap portion 6 are aligned in an upright state with the bottom portion facing down. Then, as shown in FIG. 8, the drive shaft 26 and the driven shaft 24 are provided in a cantilever structure on the box-shaped frame 29 of the alignment conveyor 3 and are not connected to the fixed frame 38.
Can be guided by a slide pack (a mechanism for sliding the box-shaped frame 29) 30 and pulled out in the left direction in FIG. 8, whereby the box-shaped frame 29 and the fixed frame 38 can be separated from each other. Since the frame 29 and the fixed frame 38 are connected to each other by connecting metal fittings, when the two are separated, it is necessary to release the connecting metal fittings to separate the frames 29 and 38. As shown in FIG. 6, the fixed frame 38 is fixedly provided on the main body frame 37, and the box-shaped frame 29
Is provided on the main body frame 37 via the slide pack 28. That is, when packing the bagged products 1 having different widths, it is necessary to replace the chain 21 with a chain corresponding to the width of the bagged product 1 to be changed. In that case, the frame 29 and the frame 38 are replaced. Separation from each other allows the chain 21 to be removed from the sprockets 22 and 25 and replaced with a chain of the desired width. However, when replacing the chain 21, it is necessary to lower the pressure of the air cylinder 31 to the atmospheric pressure to move the driven sprocket 22 in a predetermined direction in order to loosen the tension of the chain 21. And box-shaped frame 2
It is also necessary to hold the box-shaped frame 29 by, for example, a fall prevention stand (not shown) so that the 9 does not fall.

Further, the fins 5 are attached to the slat band chain 21 by fastening the points indicated by the center lines shown in FIG. 9 with bolts.

[0058]

According to the boxing method of the first invention,
When the products are sandwiched by the holding means from both sides, the upper part of each product is sucked upward by the suction means, whereby the products can be prevented from sliding down from the holding means. Therefore, when packing a bag-filled product filled with contents with a relatively large specific gravity, even if the upper end of the bag-filled product may fall sideways when the bag-filled product is sandwiched by the holding means It is possible to reliably prevent the product from falling from the holding means. Therefore, there is an effect that a bag-filled product filled with contents having a relatively large specific gravity can be reliably packed in an outer box such as a cardboard case. Of course, a bag-filled product filled with contents having a relatively small specific gravity can be surely packed in the outer box as described above. Also, the product in which the contents are packed in the box can be surely packed in the outer box as in the case of the bag-packed product.

Then, the product positioned with the holding means in the outer box is pushed into the bottom side of the outer box by the suction means,
This allows the product and the holding means to be separated from each other. Therefore, even when the holding means is pulled out from the outer box after the product such as the baggage is placed in a tight state in the outer box, the bagged article rises and spills out of the outer box as the holding means rises. That can be surely prevented. Therefore, there is an effect that the product can be packed in the outer box in a desired tight state.

Further, since the outer box is moved to a position where the outer box covers the products and the holding means for holding these products, the moving distance of the holding means is larger than that of the conventional apparatus by the amount of movement of the outer box. It can be shortened. Therefore, the holding means may be configured to move by a distance that sandwiches the aligned products from both sides. Therefore, the assembly accuracy for obtaining the predetermined positioning accuracy at the moving end of the holding means is
The shorter the moving distance of the holding means is, the lower the moving distance is. Therefore, there is an effect that the cost of the assembling work of the entire apparatus can be reduced. That is, when the holding means and the outer box are configured to be moved by short distances L ₂ and L ₃ (L ₂ + L ₃ = L ₁ ), the assembling cost is the same as when the holding means is moved over the long distance L _1. It is much cheaper than the assembling cost.

The boxing devices according to the second and seventh inventions are,
While the product is sandwiched by the holding means (second holding means) from both sides, the upper part of each product is sucked upward by the suction means, whereby the product slips off from the holding means (second holding means). It is configured to be able to prevent. Therefore, as in the first aspect of the invention, even when packaging a bag-filled product filled with a content having a relatively large specific gravity, it is ensured that the bag-filled product falls off from the holding means (second holding means). Therefore, there is an effect that these bags can be surely packed in an outer box such as a corrugated cardboard case. Of course, as in the first aspect of the invention, a bag-filled product filled with contents having a relatively small specific gravity or a product in which contents are packed in a box can be surely packed in an outer box.

In the box packing device according to the third aspect of the present invention, the product located in the outer box together with the holding means is pushed into the bottom side of the outer box by the suction means, whereby the product and the holding means are separated from each other. . Therefore, similarly to the first invention, even when the holding means is pulled out from the outer box after the product such as the bagged article is placed in the outer box in a tight state, the bagged article is It is possible to reliably prevent the product from rising and spilling out of the outer box, and thus it is possible to pack the product in the outer box in a desired tight state.

The boxing apparatus according to the fourth aspect of the present invention has a structure in which the outer box is moved to a position where the outer box covers the products and the holding means for holding these products. Therefore, as in the first aspect of the invention, the moving distance of the holding means can be shortened as compared with the conventional device by the amount of movement of the outer box. In other words, the shorter the movement distance of the holding means, the lower the assembling accuracy, so that there is an effect that the cost of the assembling work of the entire device can be reduced.

In the boxing device according to the fifth aspect of the present invention, since the ball screw or the timing belt is used as a means for moving the two holding plates of the holding means in the direction of expanding and contracting the mutual spacing, the holding plate is held. It is possible to reduce the variation in positioning accuracy at the moving end of the product, and as a result, it is possible to securely hold the product without crushing it, and to ensure that the product has an appropriate clamping force so that it does not slip off the holding plate. Can be held.

The boxing device according to the sixth aspect of the present invention drives the ball screw to rotate in the forward or reverse direction, thereby
The configuration is such that the holding plates can be accurately moved at the same time in the direction in which the distance between them is increased or decreased, and at the same time by the target distance. Therefore, in addition to the effect of the fifth invention, the structure of the holding means can be simplified and the bulk can be reduced.
