Abstract

PROBLEM TO BE SOLVED: To stabilize a carry even a step loading product row with a different number of steps by slanting a bottom conveyer and side conveyer together while keeping a prescribed angle to support a step loading product row. SOLUTION: In a bottom conveyer 58, its carrying surface is slanted while keeping a prescribed angle for a horizontal surface and the slant angle α is set to, for example 15 deg.<=α<45 deg.. Here, the direction and angle of the inclination of the bottom conveyer 58 is matched with those of the slant angle of a slant hopper. Therefore, the step loaded packaged product row HC discharged from the slant hopper can be received stably on the carry surface of the bottom conveyer 58 namely belt 64. The carry surface of the side conveyer 68 is mutually and orthogonally crossed with that of the bottom conveyer 58. Therefore, a conveyer device 50 has two mutually and orthogonally crossing carry surfaces and is formed by slanted two surface conveyer while keeping a slant angle αfor the horizontal surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for transporting a plurality of stacked product rows with certainty, even if the number of the stacked product rows is different. The present invention relates to a device for conveying a stack of product lines that can be stacked.

[0002]

[Related Background Art] Regarding the conveyance of the stacking alignment row,
The stacking product line was extruded by a pusher on a horizontal laying board, and the extruded stacking product row pushed out the front stacking product row one after another, and the laying board was replaced with a belt conveyor. There is a conveyor system.

[0003]

In the case of the press-press system,
If the number of stages in each of the stacked product rows is not the same, load collapse occurs in the stacked product rows, so that the present invention cannot be applied to the transport of a stacked product row having a different number of stages. In this regard, if the conveyor system is used, it is possible to transport even stacked product rows with different numbers of stages, but in this case, each product in the stacked product row is a rectangular parallelepiped whose shape is suitable for stacking. Must. In other words, to enable stable stacking, the upper and lower surfaces of the products must be parallel to each other. appear.

[0004] In order to prevent collapse of the cargo during transportation, it is conceivable to dispose fixed side guides on both sides of the transportation route. However, such side guides can take out a stacked product row at an arbitrary position. When the delivery destinations of the stacked product rows are individually different, distribution to the delivery destinations cannot be easily performed. The present invention has been made based on the above-described circumstances, and an object of the present invention is to obtain a product stack obtained by stacking products whose upper and lower surfaces are non-parallel and having different numbers of stages. Another object of the present invention is to provide a transfer device for a stacked product line that can stably transfer the product.

[0005]

According to a first aspect of the present invention, there is provided a conveying apparatus for a stacked product line, comprising: a bottom conveyor for receiving the stacked product line and conveying the stacked product line in a predetermined direction; And a side conveyor extending along the bottom conveyor, wherein both the bottom conveyor and the side conveyor are inclined at a predetermined angle to support the stacked product rows.

[0006] According to the above-described conveying device, the stacked product rows are conveyed as the bottom and side conveyors travel while being supported by both the bottom conveyor and the side conveyor. Preferably, the inclination angles of the bottom conveyor and the side conveyor are set so that the load of the stacked product rows is greater on the bottom conveyor than on the side conveyor (claim 2). In this case, adjacent products in the stacked product row are conveyed while maintaining good contact with each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, there is schematically shown a flow of cards in a card stacking and packaging machine, that is, a series of steps of the stacking and packaging. First, the card stacking and packaging machine includes a feeding device 2. The feeding device 2 has a plurality of hoppers 3 arranged in a line, and the cards C can be fed one by one from one hopper 3. That is, the hopper row is movable in the direction in which the hoppers 3 are arranged, and one selected hopper 3 can be positioned at the card feeding position.

The cards C fed from the feeding device 2 are supplied to the stacking and aligning device 4, where they are stacked for each predetermined number of cards. Then, the integrated card, that is, the integrated card S, after the individual cards are aligned,
It is turned 90 ° around the turning center O and supplied to the pushing position. The pushing position is defined near the beginning of the packaging section 6.

The packaging section 6 is provided with a turret 7 at the beginning thereof, and a hanging line of the packaging film F is secured between the turret 7 and the pushing position. The packaging film F is obtained by cutting the film web FW fed from the film roll FR to the hanging line into a predetermined length. During the feeding of the film web FW, a tear tape T is attached to the film web FW, and the tear tape T is fed from the tape roll TR.

The stacking card S is pushed into the pocket of the turret 7 together with the packaging film F. At this time, the packaging film F is folded around the stacking card S. After this,
With the rotation of the turret 7, the stacking card S is wrapped in the packaging film F through the body flap folding and the body sealing of the packaging film F, and from the pocket of the turret 7 to the edge folding line 8 of the packaging section 6. Is discharged.

In the process in which the stacking card S is transported on the edge folding line 8, the left and right ears of the packaging film F are folded into the side surfaces of the stacking card S and are side-sealed. The packaging of the card S is completed, and a package H as a product is obtained. After this, the ear fold line 8
At the end of, a label L is attached to the packaged product H,
Then, the packaged product H is supplied from the edge folding line 8 to the transport section 10 via the discharge line 9. Note that the label L
Is obtained by peeling off from the release sheet LW fed out from the roll LR, and a printer 12 that prints predetermined information on the label L is arranged in the feeding path of the label L.

Here, each card C is a rectangular prepaid card as shown in FIG. 2, and a magnetic barcode M is formed on the back surface along the long side of one side.
The magnetic barcode M is obtained by applying a magnetic material, and increases the thickness of the card C. Therefore, the thickness of the card C is not uniform over the entire surface, and the thickness of the long side portion having the magnetic barcode M is thicker than other portions.

As is clear from FIG. 2, the direction in which the card C is fed out from the feeding device 2 and the longitudinal direction of the card C coincide with each other. It is located on the right hand side when viewed in the direction. As described above, when the thickness of each card C is partially increased, the package H of the stacked cards S obtained by stacking the cards C is viewed in the transport direction in the edge folding line 8,
Height X ₁ of the front edge as shown in FIG. 3 becomes larger than the height X ₂ of the trailing edge. In other words, the rotation of the stacking and aligning device 4 changes the attitude of the stacking card S by 90 °, and the turret 8 reverses the transfer attitude of the stacking card S, so that the packaged product H has its front end. The long side of the card C having the magnetic barcode M on the edge is located.

Therefore, the fold line 8 and the discharge line 9
The upper and lower surfaces of the packaged product H supplied to the transport section 10 via the above are not parallel to each other, and the side surfaces are trapezoidal.
Next, referring to FIG. 4, the discharge line 9 is specifically shown. The discharge line 9 includes a chute 20, and the chute 20 extends from the end of the edge folding line 8 in parallel with the edge folding line 8. The chute 20 includes a pair of lower guides 22 and side guides 24 located on the left and right sides of the lower guides 22.

The upper end of the chute 20 has a fixed mounting table 26
The fixed side mounting table 26 is disposed at the same level position as the height level of the packaged product H transferred to the end of the edge folding line 8. A movable mounting table 28 is adjacent to the fixed mounting table 26,
The movable mounting table 28 is capable of reciprocating in a horizontal direction intersecting the edge folding line 8 and is also capable of moving up and down. Specifically, the movable mounting table 28 moves in the horizontal direction in response to the operation of the horizontal cylinder 30, and moves up and down by the vertical cylinder 32. Therefore, the movable mounting table 28 can perform a so-called block motion. The horizontal cylinder 30 moves a support for the movable mounting table 28 in the horizontal direction, and the vertical cylinder 32 raises and lowers the movable mounting table 28 with respect to the support.

A pair of delivery pushers 34 are erected on the movable mounting table 28, and these delivery pushers 34 are provided.
Are separated in a direction intersecting with the fold line 8. Due to the block motion, the movable-side mounting table 28 receives the packaged product H positioned at the end of the edge folding line 8 between the pair of delivery pushers 34, and then uses one of the delivery pushers 34 to receive the packaged product H. The packaged product H is extruded from the fold line 8 onto the fixed mounting table 26.

Further, the discharge line 9 is provided with a scraping pusher 36 above the fixed and movable mounting tables 26 and 28. The scraping pusher 36 reciprocates in the axial direction of the chute 20 by a scraping cylinder 38. Can move. Therefore, the packaged product H on the fixed mounting table 26 is discharged to the chute 20 by the scraping pusher 36. At this time, it is needless to say that the movable mounting table 28 is lowered.

At the lower end of the chute 20, a stacking unit 40 of the transport section 10 is arranged, and this stacking unit 40 is specifically shown in FIGS. The stacking unit 40 has an inclined hopper 42. The inclined hopper 42 is disposed above the lower end of the chute 20 and includes a front plate 44 and a back plate 46. The front plate 44 and the back plate 46 have an interval equal to the length of the package H (corresponding to the width when viewed from the card C) in the discharge direction of the package H on the chute 20. , Which face each other in parallel with each other. Here, as is clear from FIG. 5, the inclined hopper 42 is inclined at a predetermined angle from the vertical plane.

At the lower ends of the front plate 44 and the back plate 46, holding claws 48 for the packaged goods H are respectively arranged. Between the holding claws 48, a stacking elevator 50 is disposed below the inclined hopper 42. Have been. The stacking elevator 50 can be moved up and down between a pushing position in the inclined hopper 42 and a receiving position below the inclined hopper 42, and the ascending and descending direction is inclined according to the inclination of the inclined hopper 42. Although a mechanism for raising and lowering the stacking elevator 50 is not shown in the drawing, for example, a cam mechanism or the like can be used for this mechanism.

When the elevator 50 is at the lower receiving position as shown in FIG. 5, the elevator 50 can receive the packaged goods H discharged from the chute 20. The side guide 24 of the chute 20 is longer than the lower guide 22, and its tip is positioned so as to sandwich the stacking elevator 50 at the receiving position from both sides thereof. Therefore, the packaged product H discharged through the chute 20 is surely guided to the stacking elevator 50 and is supplied onto the stacking elevator 50.

When the stacking elevator 50 receives the package H, it rises from the receiving position to the pushing position, and pushes the package H into the inclined hopper 42 with the rotation of the pair of holding claws 48 described above. With this pushing, the inclined hopper 4
The stacked package row HC already in the stacked state within 2 rises by the height of one package H, and the number of stacked stages increases. Thereafter, even if the stacking elevator 50 is lowered to the receiving position, the stacked packaged product line HC in the inclined hopper 42 is
Are returned by the pair of holding claws 48 so that the holding claws 4
8 and does not fall off the inclined hopper 42.

Here, the number of stacking of the packaged products H in the inclined hopper 42, that is, the number of stages of the stacked packaged product line HC is not constant, and is determined when the packaged products H are stacked by the set number of individual stages. , The stacked package row HC is the inclined hopper 42.
From the front plate 44 and the back plate 46 to the conveyor device 52 of the transport section 10.
In order to realize this discharge, a plate-shaped discharge pusher 54 is arranged on one side of the inclined hopper 42, that is, on the side opposite to the conveyor device 52, as shown in FIG. It is attached to the tip of the piston rod in the discharge cylinder 56. Discharge cylinder 56
When the pin rod is extended, the discharge pusher 54 discharges the stacked package rows HC in the inclined hopper 42 to the conveyor device 50 using the pair of holding claws 48 as a guide. It should be noted that the stacking unit 40 after discharging the stacked packaged product line HC.
Stacks the packages H supplied via the chute 20 in the inclined hopper 42 to form stacked packages HC.

The conveyor device 50 has a bottom conveyor 58, which is mounted on the inclined hopper 42.
Extending from. The bottom conveyor 58 includes the driving roller 6
0 (see FIG. 7) and a driven roller 62 and a belt conveyor around which an endless belt 64 is wound. The driving roller 60 and the driven roller 62 have roller shafts of a frame 66 of the conveyor device 50 (see FIG. 7). ) Is rotatably supported.

As is apparent from FIG.
In FIG. 8, the transport surface is inclined at a predetermined angle with respect to the horizontal plane, and the inclination angle α is set to, for example, 15 ° ≦ α <45 °. Here, the inclination of the bottom conveyor 58 and the inclination angle of the above-described inclined hopper 42 coincide with each other in the inclination direction and the angle. Therefore, the bottom conveyor 58 is placed on its conveying surface, that is, the inclined hopper 42 on the belt 64. Can be stably received.

The conveyor device 50 further includes a side conveyor 68 on one side of the bottom conveyor 58, that is, on the back plate 46 side of the inclined hopper 42.
8 extends along the bottom conveyor 58. The side conveyor 68 also comprises a belt conveyor in which an endless belt 74 is wound between a driving roller 70 (FIG. 7) and a driven roller 72. The driving roller 70 and the driven roller 72 are rotatable on a frame 66. Supported.
As is clear from FIG. 7, the conveying surface of the side conveyor 68 and the conveying surface of the bottom conveyor 58 are orthogonal to each other.
Therefore, the conveyor device 50 is a two-sided conveyor having two conveying surfaces orthogonal to each other and inclined at an inclination angle α with respect to a horizontal plane.

As shown in FIG. 7, the roller shaft 76 of the drive roller 70 on the side conveyor 68 is connected to the output shaft of an electric motor 80 via a coupling 78. Frame 6 of device 50
6 is supported via a bracket 82. A bevel gear 84 is attached to the roller shaft 76, and the bevel gear 84 meshes with a bevel gear 86. The bevel gear 86 is connected to the drive roller 6 on the bottom conveyor 58 side.
0 roller shaft 88. Therefore, when the electric motor 80 is driven, the driving force is transmitted to the bevel gear 8.
Due to the engagement of the gears 4 and 86, the gears are transmitted to both the driving rollers 60 and 70, whereby the bottom conveyor 58 and the side conveyor 68 are linked and can run at the same speed.

When the row of stacked packages HC is discharged from the inclined hopper 42, the traveling of the bottom conveyor 58 and the side conveyor 68 is stopped, and
A sufficient space for receiving the stacked packaged products HC is secured at the start end of each of the upper and lower parts 8, 68. The stacked package product line HC discharged from the inclined hopper 42 is transferred to and received by the bottom conveyor 58. However, since the conveyor device 50 is inclined as described above, only the bottom conveyor 58 is provided. Instead, it is also supported by the side conveyor 68.

Thereafter, the bottom conveyor 58 and the side conveyor 68 move in conjunction with each other, and convey the received stacked package line HC by a predetermined distance, and transfer the next stacked package line HC to the start end thereof. Reserve space for receiving. By repeatedly discharging the stacked packages HC from the inclined hopper 42 and running the bottom and side conveyors 58 and 68, the stacked package rows HC in the conveyor device 50 are intermittently conveyed.

In the conveyor device 50, since the side conveyor 68 is arranged only on one side of the bottom conveyor 58, the stacked packaged goods line HC in the conveyor device 50 can be easily taken out at an arbitrary position. it can.
Therefore, the predetermined stack of packaged articles HC can be easily distributed to the delivery destination from the conveyor device 50. In addition, since the stacked package product line HC is conveyed by traveling of the bottom conveyor 58 and the side conveyor 68, even if the number of stages of the stacked package product line HC adjacent in the conveying direction is different, these stacked package product sequences HC are not conveyed. HC can be transported reliably.

Further, since the stacked packaged product line HC is supported not only by the bottom conveyor 58 but also by the side conveyor 68, stable conveyance is ensured even if the number of stages is large.
In other words, since the inclination angle α of the conveyor device 50 is set within the above-described range, the distribution load of the stacked packages row HC to the side conveyor 68 and the bottom conveyor 58 is smaller than that of the side conveyor 68. Therefore, the stable conveyance of the stacked package product line HC is maintained.

On the other hand, the inclination angle α of the conveyor device 50
Is larger than the above-mentioned range, the load of the stacked packaged goods row HC is largely distributed to the side conveyor 68, so that the adhesion of the individual packaged goods H is weakened, and the Load collapse occurs in the package row HC. Conversely, if the inclination angle α of the conveyor device 50 is smaller than the above range, the load distribution of the stacked package rows HC to be taken by the side conveyor 68 becomes too small. Load collapse occurs in the stacked package product line HC.

In particular, as described above, when the packages H whose upper and lower surfaces are not parallel are stacked to obtain a stacked package array HC, the package H in the stacked package array HC as shown in FIG. Becomes unstable. For this reason, when the inclination angle α of the conveyor device 50 is out of the above-mentioned range, the problem becomes remarkable. However, if the inclination angle α of the conveyor device 50 is set within the above-described range, the load of the stacked packaged product line HC is optimally distributed to both the bottom conveyor 58 and the side conveyor 68, and as a result, the side conveyor 68 , While preventing the collapse of the stacking package row HC, the bottom conveyor 58 allows the stacking package row HC.
Can be stably transported. In FIG. 8, the load vector W is stacking packages column HC, vector W _B is the weight distribution of the bottom conveyor 58 is responsible, vector W _S
Indicates the load distribution that the side conveyor 68 bears.

The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the package H may be supplied directly from the edge folding line 8 to the stacking unit 40, and in this case, the discharge line 9 can be omitted. In addition, the bottom conveyor 58 and the side conveyor 6
8 is not limited to a belt conveyor.

[0034]

As described above, the conveying device of the present invention (claim 1) is composed of a two-sided conveyor including a bottom conveyor and a side conveyor, and is inclined at a predetermined angle. The load of the stacked product row can be received by both the bottom conveyor and the side conveyor. As a result, it is possible to stably transport the stacked product rows having different numbers of stages without causing collapse of the load.
In addition, since the transport device is open on one side when viewed in the transport direction, the stacked product rows can be easily taken out at an arbitrary position.

When the load of the stacked product row is more distributed to the bottom conveyor side (claim 2), the collapse of the load of the stacked product row during the transport process is more effectively prevented, and the upper and lower surfaces thereof are parallel. However, stable transportation can be ensured even in the case of product stacks that are not stacked.
