Description

The present invention eliminates unevenness in the containing state of the contents of a package in which powder or granules are packed in a one-sided manner, and makes the stack thickness of a layered body of layered packages uniform. The present invention relates to a shaping device and a conveyer for shaping a laminated body so that the bundled strips are not loosened or come off and can be easily accommodated in a packaging box.

Specifically, a heat-welding sheet is welded to form a bag-like body, powder or granules are allowed to flow in through an opening facing upward, and the open opening is heat-welded to close and cut. The present invention relates to a shaping device or the like for forming a layered body in which the package bodies are horizontally layered, and for making the layered body with the uneven layered thickness uniform in layered thickness. More specifically, the entire bulky side of the stack formed by the packages having uneven thicknesses is tilted upward and vibrated so as not to damage or scatter the packages. The present invention relates to a shaping device or the like that eliminates unevenness in the thickness of a wrapper and makes the lamination thickness of a laminate uniform.

In Patent Document 1, when an unbound stack of horizontally stacked packaged products is conveyed by a bucket conveyor, a vertically movable pressing plate is used to press the upper surface of the unbound stack while the pressing plate is provided with the unbound stack. A technique is disclosed in which a vibrator is vibrated to even out the uneven contents and to reduce the stacking height. According to the technique described in Patent Literature 1, in a state in which packaged products are stacked to form an unbound stacked body, air pressure is applied from above and vibration is performed.

However, it is said that if the air pressure to be pressed becomes high, there is a possibility that the packaging sheets forming the packaged product may break, and in the case of granules mixed with large granules, the large granules are crushed by pressing. Even if the packaging sheet is not torn, there is a possibility of leaving a pressure mark on the packaging sheet.

In Patent Document 2, a stack is formed by stacking the packets upright, and the stack is turned upside down while being compressed by a compression cylinder from the side of the stack. A technique is disclosed that causes the head to return upside down. According to the technique described in Patent Document 2, the powder and granules are evenly dispersed inside the bag by inverting the compressed state and utilizing the fluidity of the powder and granules inside the bag. It is said that

However, if the compressive force when turning the laminate upside down is small, the package may fall off. There was a possibility that the eggplant granules would lose their shape and be damaged. In order to prevent the packets from falling off and the granules from losing their shape, a complicated mechanism was required to maintain the state of the stack in which the packets were stacked upright.

Patent Literature 3 discloses a technology of a bag-making machine for powder-filled bags in which flaky caustic soda is filled and the content is biased. According to this technique, the slanted plate on which the powder-filled bag is placed is vibrated and a push-up rod passes through a slit in the vibrating plate to push up the bag, thereby leveling the uneven contents. Specifically, the bag is placed on the inclined plate so that the expanded portion of the bag is above the inclined plate and the deflated portion of the bag is below the inclined plate, and the entire inclined plate is moved by a vibrator. While vibrating, the bulging portion of the filled bag is pushed up by a push-up rod through a slit opened above the inclined plate.

However, although the technique described in this document is suitable for application to a single powder-filled bag for caustic soda flakes and the like, it is applied to a laminate in which small, light, and thin medicine packages are laminated. However, there is a problem that the packages are likely to scatter and the stacked state of the packages cannot be maintained.

In Patent Document 4, as a technique for uniformizing the contained state of the contents without generating a pressing force to press the bag and damaging the contents, a non-circular cross-sectional shape such as an ellipse or a polygon is disclosed. There is disclosed a technique for uniformizing the containing state of contents such as electronic components by conveying using conveyor rollers in which rollers are arranged.

However, like the technique described in Patent Document 3, the technique described in Patent Document 4 also has the problem that it cannot be applied to a laminate in which small, light, and thin packages are stacked.

The problem to be solved by the present invention is that small, light, and thin packages in which the contents such as powders and granules are packed at one side are stacked, the thickness of the stack is uneven, and the package becomes bulky. To provide a shaping device and a conveyer for uniformizing the total thickness of a stacked layered body without damaging the packages and contents.

A first aspect of the present invention is a shaping device for uniformizing the stacking thickness of a bulky stack of packages in which contents are unevenly stacked and the stacking thickness is uneven. and an upright piece surrounding the four side circumferences, vibrating means, and tilting means, wherein the vibrating means comprises a streaky vibrating member and a collided member, and the streaky vibrating member is bulky. The collided member extends along the bottom edge of the laminate on the side and is arranged to support the bottom of the laminate, the member to be hit is arranged above the central portion of the laminate, and the tilting means is With the four circumferences of the laminate supported by the standing pieces, the bulky side of the laminate is raised with the bottom edge facing the bottom edge as the lower axis, and the laminate is placed in an inclined state. , the slanted contents of each of the packets are caused to flow down toward the opposed bottom edges, and the vibrating means creates a gap between the stack and the member to be impacted so that the content to be impacted In a state in which the laminated body is sandwiched between the member and the linear vibrating member, the laminated body is vibrated so as to collide with the collided member, so as to eliminate unevenness in the accommodation state of the contents, and the whole of the laminated body. It is characterized by uniform thickness.

The erecting piece may surround the four side circumferences so that the laminated body does not protrude to the side, and may be a shaft instead of a plate. The mode of operation of the tilting means or vibrating means is not limited, and the push-up shaft may be vertically vibrated by a crank, or magnetic repulsion may be used, and the power is not limited. The inclination angle, amplitude, and frequency are not limited as long as they are appropriately selected according to the size and contents of the package. Of course, the vibration amplitude and vibration speed of the vibration means are not limited.

Since the tilting means tilts the entire stack and tilts the packet itself in which the content is biased, the powder or granules forming the content of the packet flow down the tilted downward direction. If the contents are to flow down simply by tilting, a large tilt is required, and if the contents are simply tilted to a large degree, the contents will flow down at once to the downstream side of the tilt and the bulky position will be reversed. Cheap.

However, in the first invention, since the laminate is tilted and the linear vibrating member is brought into contact with the bulky edge of the laminate to vibrate, the powder constituting the contents of each sachet is vibrated. - Vibration is easily transmitted to the granules, the contents are easily dispersed, and the contents tend to flow down the slope. In addition, since the periphery is surrounded by the erected pieces and the members to be collided are arranged with a gap above, and the upper part of the laminated body collides, the amplitude to the laminated body can be suppressed small, and the packaging body , the outer surface of the package is hardly damaged, and the individual packages forming the laminate are not scattered.

The shape of the member to be hit may be a linear body or a planar body. A collided member is arranged above the central part of the laminate, and vibration is transmitted not only from the linear vibrating member below but also to the package at different positions above and below, so the entire laminate vibrates. be done. As a result, the contents of the sachets forming the laminate are not biased to one side, the unevenness in the containing state is eliminated, and the laminate thickness of the entire laminate can be easily made uniform.

According to the first invention, a large inclination is not required, the contents do not flow downward at once, a large amplitude is not required, and the packet is less likely to scatter or be damaged. As a result, the contents of the small, light, and thin packages can be evenly distributed, the outer surface of the packages can be easily made uniform without damaging the outer surface, and the total thickness of the laminate in which the packages are laminated can be obtained. can be brought to a uniform state. In addition, since the packages are stacked to form a laminate and then shaped, the stack thickness can be made uniform with higher production efficiency than when each package is individually shaped.

According to a second aspect of the present invention, in the shaping apparatus according to the first aspect, the tilting means causes the laminate to be tilted, and then the vibrating means vibrates the linear vibrating member. . In the second invention, the first step tilts and the second step vibrates.

According to a third aspect of the present invention, in the shaping apparatus according to the first aspect, the tilting means tilts the laminate while the vibrating means vibrates the linear vibrating member. In the third invention, it is vibrated while being tilted. According to the third aspect of the invention, since the tilting and the vibration that form the shaping action are performed at the same time, even if the powder and granules are mixed with powder and granules having different particle sizes, the content can be easily separated. It has the effect of facilitating uniform thickness of the body.

According to a fourth aspect of the present invention, in the shaping apparatus of the first aspect, the distance adjusting means further includes distance adjusting means, and the distance adjusting means adjusts at least one of tilt state adjusting means and height adjusting means. wherein the tilting state adjusting means can change the tilt angle of the tilting state by the tilting means, and the height adjusting means can change the separation distance between the stacked body and the impacted member. The separation distance adjusting means can adjust the separation distance between the uppermost package of the laminate and the impacted member before vibration is generated.

In the fourth invention, at least one of the tilt state adjusting means and the height adjusting means includes a separation distance adjusting means. In order to increase the separation distance, the tilt angle of the stacked body should be decreased and the position of the member to be collided with should be raised. All that is necessary is to lower the position of the colliding member. According to the size/material of the packet, the nature/quantity of the contents, etc., the separation distance between the package on the top layer of the stack and the member to be impacted before vibration is generated is adjusted by the separation distance adjusting means. Just do it.

For example, in the case of a packet with a large surface area, if only the inclination is increased, the contents tend to flow downwards at once. The amplitude should be increased. When the content of the packet is small powder, the inclination may be increased so that the content can be easily dispersed. When the packet is small, the separation distance from the collided member should be reduced so that the packet is less likely to scatter. According to the fourth invention, according to the size/material of the package, the nature/quantity of the contents, etc., the thickness of the package is more appropriately made uniform, and the total thickness of the laminate is reduced. can be made uniform.

A fifth aspect of the present invention is a conveyer including the shaping devices of the first to fourth aspects, wherein a plurality of the shaping devices are arranged adjacent to each other, and the collided member of the plurality of shaping devices is , of the standing pieces that form an integral streak-like member and extend in the same direction as the streak-like vibrating member and that intersects with the collided member, the standing piece has a notch at the center of the top thereof; The height of the standing piece is higher than the stack thickness of the laminate except for the notch.

In the fifth aspect of the present invention, a plurality of shaping devices are arranged side by side on the conveyer, and the collided member positioned above the stack is connected to form an integral streak member. Since the member to be impacted is arranged so as to fit in the notch, even if the height of impact of the member to be impacted is changed according to the number of stacked layers, the package is less likely to scatter when tilted or vibrated. . By sharing the driving device and the impacted member of the adjacent shaping device, not only the mechanism is simplified, but also the number of layers to be laminated can be easily applied and the versatility is high.

For ease of understanding, the overall process of manufacturing the packet will be described, and the shaping device of the present invention will be described in detail. Of course, the examples are illustrative only and are not limiting. The packaging machine including the shaping device 1 includes, from the upstream side, a package manufacturing device 300, a package transporter 400, a package stacking device 500, a transport conveyor 600 including the shaping device 1, and a stacking machine 700. Each device is arranged in this order (see FIG. 1). The packet manufacturing apparatus 300 has three filling and packaging units 301 arranged in parallel, and a packet conveying machine 400 and a stacking device 500 are arranged for each filling and packaging unit. Although not shown, a packing machine may be provided downstream of the strapping machine 700 .

The packet 100 is first manufactured by the packet manufacturing apparatus 300 into long, continuous packets, and then separated by cutting the heat-welded portions connecting the adjacent packets (see FIG. 3). When each package is dropped from the package manufacturing apparatus 300 to the package conveying machine 400 and delivered, it is laid down so that the bulky side faces downstream and is conveyed to the stacking device 500 . The stacking device 500 stacks the number of packages that meet the product standard, and delivers the stack 200 to the conveyor 600 in a state in which the packages have not been bundled and shaped to have a uniform thickness.

The transport conveyor 600 is an intermittent transport conveyor that intermittently stops every time the stacked body 200 is transported downstream a predetermined distance (see FIG. 1). Here, all of the receiving positions 610 of the transport conveyor facing the three stacking devices 500 are empty (see the broken line in FIG. 1), and the stacks 200 are simultaneously received from each of the stacking devices 500 when the transport is intermittently stopped. Passed. Each stacking device 500 stacks the stack to be delivered next while the transport conveyor 600 intermittently transports the stack 200 three times.

While the laminate 200 is conveyed downstream by the conveyer 600, the lamination thickness of the entire laminate is made uniform by the shaping device 1, and the laminate is delivered to the strapping machine 700 at the delivery position 620 (see FIG. 2). In the strapping machine 700, a heat-sealing film is wrapped around a laminate having a uniform thickness, and the ends of the heat-sealing film are heat-sealed to bind the laminate.

Here, the reason why the contents of the packet 100 are in a one-sided state will be described with reference to FIGS. 3 and 4. FIG. The packet 100 may be a four-side seal obtained by stacking two heat-sealable sheets and heat-sealing the four sides thereof, or a three-side-sealed heat-sealed heat-sealed sheet obtained by folding the heat-sealable sheet in half and heat-sealing the three sides. Moreover, the packaging bodies forming the laminate are not limited to the case where they are separated one by one, and a plurality of packaging bodies may be connected to form one unit. In this embodiment, the adjacent packets 100 are one sheet/one unit (see FIG. 2). Although the size of the packet is not limited, the length of the two packets arranged side by side is about 140 mm, and the width is about 120 mm.

The package manufacturing apparatus 300 is composed of three filling and packaging units 301 arranged in parallel, and simultaneously manufactures packages welded on all sides (see FIGS. 1 and 3). Each filling and packaging part 301 continuously feeds the heat-welding sheet 310 extending in a belt shape in the vertical direction, and continuously heat-welds the heat-welding sheet by sandwiching the heat sealer 320 in the vertical direction to form a cylindrical shape (FIG. 3). (A) see figure).

Further, the cylindrical heat-welded sheet is heat-sealed at the bottom by a horizontal heat sealer 330, and powder/granules having a volume meeting the product standard are filled by a filling machine 340 from the upper inlet, which is not heat-sealed. Drop filling. After filling, the upper inlet is also heat-sealed by a transverse heat sealer, and the four sides of the packet are heat-sealed.

Therefore, the contents are enclosed in a state of being biased toward the lower side of the container (see FIG. 4(A)). In this state, the continuous packages are cut off unit by unit by the cutting machine 350 and conveyed to the package conveying machine 400, so that the contents reach the stacking device 500 while the contents are one-sided. In each stacking device, each time a package is received, the elevator descends by an amount corresponding to the height of the package, receives a predetermined number of packages, stacks them, and pushes them out by pushing means 510 moving in the horizontal direction. , the stacked bodies are transferred from the stacking device 500 in which the stacks are arranged side by side to the conveyer 600 (see FIG. 3B).

At the stage when the packages are stacked, the contents of each package 100 are biased, so that the stack 200 also has a non-uniform stacking thickness (see FIG. 4(B)). ). If banding is performed in a state where the lamination thickness is uneven, the thickness of the laminated body gradually becomes uniform in the transport process after banding, and a gap is formed between the laminated body 200 and the band body 210. , the binding of the belt is easy to loosen, and the loosened belt is easy to come off. Moreover, if the stacking thickness is uneven and the bulky packaging is to be packed in the packing box, it is necessary to increase the opening height of the packing box (refer to the bulky height H in FIG. 4(C)). The thickness becomes uniform and the space in the packing box becomes large.

On the other hand, even if the contents of the package are the same, if the entire stack is made uniform in stacking thickness (see bulk h in FIG. Since it is easy to adhere to the entire circumference of the laminate and a gap is less likely to form around the band, the binding of the band is less likely to loosen. Moreover, since the packaging becomes easy even if the opening height of the packaging box is lowered, the volume of the packaging box can also be reduced.

Now, the shaping apparatus 1 of Example 1 will be described in detail with reference to each drawing. The shaping device 1 is provided on an intermittent transport conveyor 600 disposed between the stacking device 500 and the strapping machine 700, and is downstream of a receiving position 610 for receiving the stack 200 from the stacking device. It is provided at a stop position on the upstream side of the delivery position 620 that delivers the laminate to the machine (see FIGS. 1, 2 and 5).

Hereinafter, in order to facilitate understanding, the side surface facing the downstream side of the laminate is referred to as the front surface, and the side surface facing the upstream side is referred to as the rear surface, in accordance with FIG. The bulky side of the laminate is called the left side, and the edge facing the bulky side is called the right side.

The shaping device includes upstanding pieces surrounding the four side circumferences of the stack, vibrating means 10 for vibrating the stack, and tilting means 20 for tilting the stack and causing the contents to flow down from the bulky side. The standing pieces surrounding the left and right side surfaces of the laminate are composed of a pair of standing walls 30 elongated along the conveying path of the intermittent conveying conveyor 600, and the standing pieces surrounding the front and rear surfaces of the laminate It consists of a set of delivery pieces 42 provided on the conveyor (see FIG. 5(A)). All standing pieces extend higher than the stack thickness of the laminate (see FIG. 5(B)). Here, an example in which all of the standing pieces are made of plates is shown, but it goes without saying that a plurality of shafts may be erected at narrow intervals to function as the standing pieces.

A pair of upright walls 30 along the right and left sides are removed at the stack receiving position 610 on the side facing the stacking device 500 so that the stack can be received from the side of the transport conveyor, and the side facing the stacking device 500 is removed. It extends to an outfeed position so that the stack can be pushed out to the side of the transport conveyor at position 620 (see FIG. 2). The delivery piece 42 for delivering the stack as a set has its open end facing the stacking device 500 bent outward to widen the opening width so that the stack can be easily received from the side. In addition, each delivery piece 42 has a vertical notch 41 at the center of the top (see FIG. 5(B)).

In the first embodiment, the vibrating means 10 also functions as the tilting means 20, and tilts the stacked body by raising the bulky side with the bottom edge portion 230 facing the bulky side 220 of the stacked body as the lower axis, and streak vibration. The member 31 is vertically vibrated (see FIGS. 5 and 6). The laminated body may be vibrated after being tilted, or may be vibrated while being tilted.

The vibrating means 10 includes a linear vibrating member 31 that pushes up and vibrates the laminate, and a collided member 40 that causes the vibrated laminate to collide and vibrate (see FIGS. 5 and 6). In addition, in the gap between the conveyer 600 and the upright wall 30 along the right side of the laminate, a slide-off prevention member 50 extending in a streaky shape along the conveying path is disposed, and when the laminate is tilted and vibrated, In addition, the packet 100 overlaid on the laminate is prevented from slipping down into the gap.

The streaky vibrating member 31 extends across three stop positions along the bottom edge of the bulky side of the stack, and is arranged on the placement surface of the transport conveyor 600 so as to support the bottoms of the three stacks at the same time. (see FIG. 5). The linear vibrating members 31 extending over the three stop positions may share a single drive mechanism and vibrate in synchronization. may

The driving mechanism 630 may vertically vibrate the linear vibrating member 31 by a well-known motor and crank mechanism, but is not limited to this. . The width of the streaky vibrating member 31 may be changed depending on the size of the package, etc., and is not limited. The length of the streaky vibrating member 31 extending along the conveying path is not limited, either, as long as it is provided at a plurality of or a single stop position depending on the fluidity of the contents.

The member to be hit 40 is disposed above the central portion of the laminated body 200 with a gap from the top surface of the laminated body, extends in a striped shape over three stop positions, and is aligned at each of the stop positions. There are two impacted members 40 (see FIG. 5A). The impacted member 40 may be separately arranged at each stop position. The thickness, width, etc. of the member to be hit are not limited.

The collided member 40 can adjust the collision height with the laminated body by an elevator 60 forming a height adjusting means (see FIG. 5(B)). Specifically, the height of the member to be impacted 40 is adjusted so that it fits in the cutouts 41 of the plurality of delivery pieces and is positioned lower than any of the surrounding standing pieces. Specific examples of height adjustment will be described later together with the tilt angle adjusting means.

Since the height of the impacted member 40 is adjusted so as to be accommodated in the notch 41, the delivery piece 42 and the impacted member 40 do not interfere with each other even when the transport conveyor 600 is driven. In addition, if the notch 41 is deepened, it is easy to adjust the collision target member 40 to a lower position, and even if the laminated body has a small number of laminated bodies, the collision target member can be reliably secured when the laminated body is vibrated. can collide with

Since the laminate is sandwiched between the collided member 40 and the linear vibrating member 31 from above and below, even if the linear vibrating member 31 is vertically vibrated and pushed up, the packet collides with the collided member. , Do not jump out of the area surrounded by the standing pieces. Each time the laminated body 200 is vibrated, it is slightly colliding with the colliding member 40 and vibrates. Therefore, even if the colliding member 40 is only fixed in position, vibration is applied to different positions above and below the laminated body. be able to.

The vibrating means vertically vibrates the linear vibrating member 31 while the stack is stopped at the stop position of the conveyer 600 . The transport period and the stop period of the intermittent transport conveyor are not limited. about 1 second. If it is desired to lengthen the vibrating period according to the fluidity of the contents, the lengths of the linear vibrating member 31 and the collided member 40 can be increased, and the number of stop positions for vibrating the stack can be increased. The lamination thickness of the laminate can be made uniform without changing the efficiency.

The vibrating means 10 is preferably capable of adjusting the vertical amplitude and frequency of the linear vibrating member 31 . For example, when the drive mechanism is composed of the servomotor 11 and the crank mechanism 12, the operation of the servomotor may be controlled to control forward/reverse rotation and the number of revolutions per unit time of the servomotor. Further, the amplitude and frequency may be adjusted by adjusting the length of the crank arm 13 (see FIG. 5(B)).

The amplitude is not limited as long as it can be changed according to the fluidity of the contents, the size of the package, etc. For example, if the laminated body is tilted and vibrated with an amplitude of about 5 mm to about 20 mm, good. The number of vibrations per second (vibration speed) is not limited as long as it can be changed depending on the fluidity, volume, average particle size, etc. of the contents, but for example, in the case of pharmaceutical powders, it is about 5 per second. The number of times of vibration may be from 10 times to about 10 times.

Here, two modes in which the vibrating means 10 vibrates the linear vibrating member 31 will be specifically described with reference to FIGS. 6 and 7. FIG. FIGS. 6A to 6D show the case where the laminated body is tilted and then vibrated, and FIGS. 7A to 7D show the case where the laminated body is tilted. A case of vibrating is shown.

When the laminate is tilted and then vibrated (FIG. 6), as the first step, the position of the motor 11 is raised (see the arrow in FIG. 6A), the linear vibration member 31 is raised, and the laminate is The bulky side 220 is lifted to a desired height using the bottom edge 230 facing the bulky side as a lower shaft (see FIG. 6(B)). Here, in order to prevent the angle of inclination from becoming excessively large, the height of lifting the bulky side is about 1/5 to about 1/4 of the left and right width of the packet, and the bulky side is about 25 mm to about 1/4. I tried to lift it by about 30mm.

As a second step, while the laminated body 200 is kept in an inclined state, the striped vibrating member 31 is vibrated in small steps with an amplitude of about 10 mm up and down to cause the top surface of the laminated body to slightly collide with the collided member 40 . (see FIG. 6(C)), and the whole is lowered together with the motor (see FIG. 6(D)). At this time, the vibration frequency was about 8 times per second, and the period of applying the vibration was about 1 second per one stop position, and about 3 seconds in total for the three stop positions. When the laminate was vibrated under the above conditions, even if it was intermittently conveyed downstream for a short period of time, the contents of the laminate were contained evenly, and the thickness of the entire laminate could be made uniform. (See FIG. 6(D)).

When the laminate is tilted and vibrated (FIG. 7), the linear vibrating member 31 is also vibrated while the motor 11 itself is moved up and down. When the motor is raised, the inclination angle gradually increases, and the strength with which the top surface of the laminate collides with the collided member gradually increases (FIGS. 7A and 7B). (see FIG. 7(C) and FIG. 7(D)). The up-and-down motion of the motor and the amplitude and frequency of the linear vibrating member may be set separately.

After the laminate 200 collides with the collided member 40, only the linear vibration member 31 needs to be vibrated (see the arrow in FIG. 7(C)). When lowering, the motor 11 and the linear vibrating member 31 are lowered together (see the arrow in FIG. 7(C)). The number of times of vibration, the lifting time, and the like may be the same as in the case of tilting and then vibrating the laminate. In this case as well, even if the intermittent transport is carried out for a short period of time, the stack thickness of the entire stack can be made uniform (see FIG. 7(D)).

Next, specific aspects of the tilting state adjusting means and the height adjusting means, which constitute the separation distance adjusting means, will be described with reference to FIGS. 8 and 9. FIG. FIGS. 8A and 8B show two examples in which the tilt state of the stacked body 200 is adjusted by the tilt state adjusting means, and FIGS. It shows an example in which the collision height with the member is adjusted. The separation distance adjustment means adjusts the separation distance between the uppermost package of the laminate and the collision member before vibration is generated by at least one of the laminated body inclination adjustment means and the collision member height adjustment means. It is adjustable.

The tilt state adjusting means changes the initial lifting position of the linear vibrating member 31 by tilting means 20 which also functions as the vibrating means 10, for example, the position adjusting means of the motor 11, and adjusts the tilt angle for tilting the laminate. It is sufficient if it is possible (see FIG. 8). Similarly to the amplitude, the tilt angle is not limited. Even if there is, the contents can be leveled in a short time, and the contents do not flow down to the inclined downstream side at once.

In addition, it is also possible to adjust the impact force when the laminated body collides with the collided member 40 by making the inclination angle of the laminated body gentle by the inclination state adjusting means. For example, when the contents are granules (see FIG. 8(B)), there is a possibility that the granules may be damaged or traces of the granules may appear on the packet due to the impact of vibration. When the laminated body is tilted and then vibrated, the tilt angle is made smaller than in the case of powdery particles (see FIG. 8(A)), and the impact on the impacted member 40 is made gentler, so that the granules and the particles are separated. Damage to the wrapper can be prevented. At this time, the impact may be softened not only by reducing the tilt angle but also by reducing the vibration frequency per second.

The collision height of the member to be hit 40 can be adjusted by an elevator 60 (see FIG. 5(B)) as a height adjusting means (see FIG. 9). The collision height is determined when the bulk of the stack before shaping is changed, such as when the number of stacked packages 100 is changed, or when the volume of the contents is changed (see FIGS. 9A and 9B). ) should be adjusted. In addition, when changing the tilt angle, the collision height may also be adjusted (see FIG. 8).

Next, another form of the collision target member 40 will be described with reference to FIG. 10 . Each figure in FIG. 10 shows a side view along the conveying path of the intermittent conveyer, FIG. 10(A) shows a state in which the laminate is conveyed, FIG. The state in which the laminated body is vibrated is shown. When the stack is vibrated at a plurality of stop positions, the stack thickness of the stack is reduced as the stack is transported downstream (see FIG. 10(A)).

For a laminate with a reduced thickness, when it is vibrated up and down with the same inclination angle and amplitude, it is less likely to collide with the collided member. The thickness of the impacted member 45 is increased stepwise so that the position 44 of the lower portion of the member is lowered stepwise (see FIG. 10(B)). As a result, even at the stop position on the downstream side where the bulk of the laminate is being reduced, the laminate can be reliably collided with the member to be collided without changing the amplitude or the like.

In this case, even if the laminate is vibrated at a plurality of stop positions, the impacted member 45 can be integrated and the collision heights at the plurality of positions can be adjusted by a single height adjusting means. Although not shown in the drawings, each stop position is provided with an independent member to be hit and height adjusting means, and the height position of each member to be hit is changed to a different collision height according to the reduction in bulk. You can adjust it to fit.

In a second embodiment, a shaping device 2 in which the vibrating means 110 and the tilting means 120 are separate operating mechanisms will be described with reference to FIG. FIG. 11(A) shows a state in which the tilting means 120 is operated in the direction of the arrow. FIG. 11(B) shows a state in which the laminate is tilted and then vibrated by the vibrating means 110 . FIG. 11(C) shows a state in which the laminated body is vibrated to collide with the collided member 40 . FIG. 11(D) shows a state in which the laminated body 200 has a uniform thickness. The same reference numerals are attached to the configurations that are common to the first embodiment, and the description thereof is omitted.

Although not shown, the vibrating means 110 vertically vibrates the linear vibrating member 31 by means of a crank mechanism or the like, as in the first embodiment. The tilting means 120 pushes up the mounting plate 121 on which the layered body 200 is placed with a shaft, thereby tilting the bulky side 220 of the layered body higher (see FIG. 11B).

Specifically, a first rotating shaft is provided on the lower left side of the placing plate 121 on which the laminate is placed, and a fixed shaft 122 for tilting the placing plate is provided. A second rotating shaft 123 is provided on (the bulky side), and a push-up shaft 124 that pushes up from below is rotatably attached to the second rotating shaft (see FIG. 11(A)).

The drive section of the transport conveyor is arranged above the mounting plate 121, and the delivery piece 46 surrounding the front and rear of the stack is vertically provided from the drive section (see FIG. 11). The delivery pieces 46 surrounding the front and rear of the laminate are moved along the platen plate 121 to slide the laminate 200 on the platen plate 121 and transport it downstream. Although the form of the conveyer is not limited, for example, an electromagnetically driven linear conveyer is preferable because the conveying interval can be freely set.

First, the push-up shaft 124 is lifted, the mounting plate 121 is tilted counterclockwise in the drawing, and the bulky side of the stack is lifted with the bottom edge portion 230 facing the bulky side of the stack as a lower axis, and the stack 200 is tilted. (See FIG. 11(A)). When the mounting plate 121 is tilted to the desired tilt angle, the vibrating means 110 is activated (see FIG. 11(B)).

The streaky vibration member 31 comes into contact with the bottom portion of the stacked body that is already in an inclined state, vibrates the stacked body 200 up and down, and causes the top surface of the stacked body to collide with the collided member 40 (FIG. 11(C)). (see diagram). When the push-up shaft 124 and the linear vibration member 31 are lowered, the mounting plate 121 and the laminate 200 are returned to the horizontal state (see FIG. 11(D)).
