DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for vertically inverting a laminate of sheet-like articles such as paperboard paper and punched blanks for paperboard.

[0002]

2. Description of the Related Art For example, punched blanks, which are printed by a printing machine and punched into a predetermined shape by a punching machine, are temporarily stacked with the printing surface thereof usually as an upper surface to form a laminated body. Is fed into the sack machine one by one from the laminate and formed into a paper container.

[0003] In this case, in order to make the printing surface of each punched blank the outer surface of the paper container, the printing surface of each punched blank is generally sent to the suck machine as a lower surface.

[0004] Therefore, the laminated body of the punched blanks is turned upside down before being sent to the suck machine. Conventionally, such a stacked body has been turned upside down manually.

[0005]

Since the laminated body of the sheet-like articles becomes considerably heavy when the number of the laminated bodies is large, it requires a very large amount of labor to perform the upside down operation manually.

Accordingly, an object of the present invention is to provide an apparatus which can turn a laminate of sheet-like articles upside down without requiring labor and without breaking the laminate.

[0007]

A feature of the present invention is that a support and a pair of right and left opposing guides are provided, and the two guides can be turned upside down about a longitudinal axis. On the upper and lower ends of each guide, a mounting body on which a stack of sheet-like articles carried in between the two guides is placed is provided, and at least one of the upper and lower mounting bodies is provided. Both plans
Displaces the inner body from the inner position in the opposite direction to the outer position in the opposite direction.
Thus, the position can be changed to a position where the stacked body placed thereon can be dropped.

[0008] Further, it is preferable that the mounting body, whose position can be changed to a position where the stack can be dropped, is formed as a roller rotatable about an axis orthogonal to the moving direction.

Further, it is preferable that an elastic body is provided for pressing at least one of the upper and lower mounting bodies against the upper surface of the laminate.

[0010] It is preferable that the pair of left and right guides be relatively movable in a direction facing each other. In this case, it is preferable that a transporting body for transporting the stacked sheet-like articles in the lateral direction is provided, and that the support be relatively movable up and down relative to the transporting body. Preferably, it is relatively movable in the lateral direction.

[0011]

According to the present invention, the upside down of the laminate of the sheet-like articles is performed as follows.

First, a laminate of sheet-like articles is carried in between a pair of left and right guides facing each other. This laminate is placed on a placing body below each guide. Thereafter, the two guides are inverted with respect to the support about the longitudinal axis. Thus, the stacked body is turned upside down. The stacked body that has been turned upside down is placed on the placing body that has moved from the upper side to the lower side due to the inversion of the guide body. Then, the mounting body, which is located on the lower side, moves from the mounting position of the stacked body, so that the mounting body falls from the space between the opposing guide members. Thereby, the laminate is carried out of the reversing device. At this time, the stacked body falls while being guided by both guides, so that the stacked body is prevented from collapsing.

The mounting body, which can be moved to a position where the stacked body can be dropped, is formed as a roller rotatable about an axis perpendicular to the moving direction, so that the mounting body rolls with respect to the stacked body during the movement. Move. This prevents the mounting body from damaging the sheet-like articles constituting the laminate.

The stack is sandwiched between the upper and lower mounts by providing an elastic body for pressing the mounting body against the upper surface of the stack. This prevents the stack from collapsing when inverted.

Since the pair of left and right guides are relatively movable in the direction in which they face each other, the distance between the two guides is increased when the stack is carried in between the two guides.
The loading can be made easy.

A transport body for transporting the laminate in the lateral direction;
Since the support is movable up and down relatively with respect to the carrier, the efficiency of the reversing operation can be increased. That is, the stack to be inverted is positioned below both guides by the carrier. Next, in a state where the facing distance between the two guides is widened, the stack is carried in between the two guides by lowering the two guides relatively to the transporting body.
Next, the interval between the two guides is reduced, and then the two guides are raised with respect to the carrier, so that the stacked body is placed on the mounting body. Next, by rotating the guide, the laminate can be turned upside down in the same manner as described above.

Furthermore, since the support is movable in the lateral direction relatively to the carrier, the stacked body turned upside down is different from the position where the stacked body is carried between the two guides. Can be transported to a location. During this time, the stack to be next inverted can be transported by the transport body, so that the efficiency of the inversion operation can be improved.

In FIG. 1, the upper and lower mounting members 30 and 31 swing about the longitudinal axis. That is,
Support shafts 36, 37 around the longitudinal axis are rotatably mounted on brackets 34, 35 protruding outward in the facing direction of the guides 10, 11, respectively. Arms 38 and 39 are attached to both ends of the support shafts 36 and 37, respectively. The mounting bodies 30 and 31 are attached to the arms 38 and 39.
As a result, the mounting bodies 30 and 31 can swing around the support shafts 36 and 37, and as shown in FIG.
The position can be changed from an inner position in the opposing direction of 11 to an outer position in the opposing direction of both guides 10 and 11.

In the present embodiment, the mounting members 30 and 31 whose positions can be changed are rollers rotatable about a longitudinal axis which is orthogonal to the moving direction.

Also, arms 40,
The telescopic rods of the fluid pressure cylinders 42 and 43 are connected to the respective arms 40 and 41. The cylinders of the fluid pressure cylinders 42 and 43 are the guides 10 and 11

In this embodiment, the fluid pressure cylinder 42,
Arms 40 and 41 are inserted into a telescopic rod 43 so as to be movable in the longitudinal direction of the rod, and are prevented from coming off by stoppers 44 and 45 attached to the distal end of the rod. The fluid pressure cylinders 42, 43
Compression coil springs 46 and 47 are fitted to the telescopic rods, and the arms 40 and 41 are pressed against the stoppers 44 and 45 by the springs 46 and 47.

Thus, the mounting bodies 30, 31 swing about the longitudinal axis by the expansion and contraction of the fluid pressure cylinders 42, 43, so that the guide members 10, 11 are located at the inner position in the facing direction and the outer position at the facing direction. Will be repositioned.

Next, the lifting conveyor 4 is disposed below the reversing device 3. As shown in FIG. 5, the lifting conveyor 4 is attached to a rail 48 attached to the frame 2 so as to be able to move up and down.

A pair of upper and lower chain sprockets 49 and 50 are attached to the frame 2, and a chain 51 wound around the chain sprockets 49 and 50.
Are connected to the lifting conveyor 4.

As a result, the chain conveyor 50 is rotated by the motor 52, so that the elevator 4 is moved up and down, so that the conveyor 4 is vertically movable relative to the reversing device 3.

The lifting conveyor 4 includes a blanking blank 54.
Is driven so as to convey the stacked body 53 in the front-rear direction.

The feed conveyor 6 is disposed behind the lifting conveyor 4 (to the right in FIG. 5). The stacked body 53 of the punched blanks 54 that have been printed and stacked on the feed conveyor 6 is placed with its print surface facing upward. Then, the lifting conveyor 4 and the feeding conveyor 6 are driven to rotate, so that the stacked body 53
Is transferred from the feeding conveyor 6 to the lifting conveyor 4.

The stock conveyor 7 is arranged in front of the lifting conveyor 4. The stack 53 is transferred from the lifting conveyor 4 to the stock conveyor 7, and the stack 5 is transferred from the stock conveyor 7 to the lifting conveyor 4.
3 can be transferred.

The delivery device 5 is arranged above the stock conveyor 7.

The feeding device 5 shifts the punched blanks 54 from the laminated body 53 in the feeding direction so that the punched blanks 54 in the lowermost layer are located on the front side in the feeding direction (left side in FIG. 5). In this state, the mixture is fed to the delivery conveyor 8 in a state of being superposed.

The delivery conveyor 8 is constituted by a pair of upper and lower belt conveyors, and sandwiches the punched blanks 54 which are delivered from the delivery device 5 and which are shifted from each other, and sends them to a suck machine (not shown). In this way, by keeping the blanks 54 shifted from each other, the close contact between the blanks 54 is released, and the blanks 54 are surely supplied one by one to a suck machine (not shown).

As shown in FIGS. 18 to 21, the delivery device 5 includes a belt conveyor 55 in contact with the lower side of the laminate 53, and a rectangular plate-shaped doctor 56 in contact with the laminate 2 in the forward direction in the delivery direction. ing.

The belt conveyor 55 includes a drive shaft 85 attached to the frame 2 of the pre-feeder 1 and driven by a motor 59, a driven shaft 57, and a plurality of belts wound around the drive shaft 85 and the driven shaft 57. 58.

The friction coefficient of the outer peripheral surface of the belt 58 is such that the frictional force in the feeding direction acting between the belt 58 and the punching blank 54 is smaller than the frictional force in the feeding direction acting between the punching blanks 54. Is also expected to grow. The vertical distance between the doctor 56 and the belt conveyor 55 is adjustable.

Further, four guide rods 59 are mounted on the frame 2 so as to be adjustable in position in the left-right direction. Each guide rod 59 has a pair of positioning members 60.
And a pair of pressing belt mechanisms 61 are mounted so as to be capable of adjusting the position in the feeding direction and the vertical direction.

The pair of positioning bodies 60 are
By contacting the left and right side surfaces of the laminated body 53, the stacked body 53 is positioned in the left and right direction.

Each pressing belt mechanism 61 has a belt 63 driven to rotate around a front-rear axis by a driving motor 62.
It has. The belt 63 is in contact with the left and right side surfaces and the lower portion of the stacked body 53 on the rear side in the sending direction, and is driven to rotate in the direction of the arrow in FIG.
Due to the rotation of the belt 63, the rear side in the feeding direction of the laminated body 53 in contact with the belt 63 is pushed downward, and the rear side portion 54 of the lowermost punched blank 54 in the feeding direction.
a can be pressed against the upper surface of the belt 58 of the belt conveyor 55.

As shown in FIG. 20, the feed direction of the belt conveyor 55 is a position in front of the feed direction of the stacked body 53 placed on the belt conveyor 55, and
As it approaches the doctor 56, the direction is set to be away from the stacked body 54 in the stacking direction downward.

That is, the drive shaft 8 of the belt conveyor 55
An intermediate roller 6 idles around an axis parallel to the drive shaft 85 on the inner peripheral side of the belt 58 wound around the driven shaft 57 and the driven shaft 57.
The intermediate roller 64 pushes up the belt 58 at a position forward of the center of gravity of the stacked body 53 placed on the belt 58 in the feeding direction. The intermediate roller 64 is attached to the frame 2 via a positioning means (not shown) so that the position of the intermediate roller 64 can be adjusted in the feeding direction and the vertical direction.

Thus, the feeding direction of the belt conveyor 55 is indicated by an arrow in FIG.
On the rear side in the feeding direction, along the bottom surface of the stacked body 53, and on the front side in the feeding direction than the intermediate roller 64, it separates downward from the stacked body 53 as it approaches the doctor 56.

In the delivery device 5, the doctor 5
6 from above and below the belt conveyor 55, it is assumed that the punched blanks 54 are already superposed and fed in a state shifted from each other in the feeding direction (note that, at the beginning of the feeding, the punched blanks The positions of the doctor 56 and the intermediate roller 64 are adjusted so that the sheets 54 are sent out in a state shifted from each other in the feeding direction.)

The height of the polymer from the upper surface of the belt 58 of the polymer of the punched blanks 54 fed from above and below the doctor 56 and the belt conveyor 55 is shifted from each other in the feeding direction. From that
The maximum value is obtained at intervals corresponding to the shift amount, and the maximum value becomes smaller toward the rear in the feeding direction.

Accordingly, the gap between the lower surface of the doctor 56 and the upper surface of the polymer of the punching blank 54 fed from above and below the doctor 56 and the belt conveyor 55 changes gradually.

On the other hand, when the belt conveyor 55 is driven,
The rearward portion 54a of the lowermost layer of the punched blank 54-1 in the feed direction in the laminate 53 is in contact with the belt 58, and the frictional force in the feed direction acting between the rear portion 54a in the feed direction and the belt 58 is as follows. It is larger than the frictional force acting between the punching blanks 54 in the feeding direction. Therefore, the lowermost blank 54-1 is pushed by the belt conveyor 54 in the feeding direction.

The feeding direction of the belt conveyor 55 is set at a position on the front side in the feeding direction of the stacked body 53, and separates downward from the stacked body 53 as it approaches the doctor 56. As a result, a space 65 in which the front side of the punched blank 54 on the lower side of the stacked body 53 in the feeding direction can move up and down is formed at a position behind the doctor 56 in the feeding direction.

Then, the lowermost blank 5-4
The front side of the feeding direction 1 is pushed in the feeding direction and pressed against the doctor 56, and is bent and deformed in the space 65, thereby lowering from the position shown by the phantom line to the solid line position in FIG. An attempt is made to enter between the conveyor 58.

As a result, the lowermost blank blank 54-
1 is the lower surface of the doctor 56, the doctor 56 and the belt 5
When the gap between the punch blank 54 and the upper surface of the polymer, which is fed from above and below, is smaller than a dimension through which one punch blank 54 can pass, feeding is restricted.
Further, when the gap becomes larger than a dimension that allows one punch blank 54 to pass, the punch blank 54 is sent out from between the upper and lower sides of the doctor 56 and the belt 58 as shown in FIG. Become.

Next, the blank blank 54-
1 moves in the feed-out direction, the second blank 54-2 from the bottom layer is newly added to the blank blank 54 of the bottom layer.
As a result, the rear portion 54a in the feeding direction comes into contact with the belt 58, and the above operation is repeated.

As a result, the lower blanks 54 are located on the front side in the feeding direction, and are sent out in a state shifted from each other in the feeding direction.

According to the feeding device 5, the front side of the lowermost blank 54-1 in the feeding direction is pushed by the belt conveyor 55, and the doctor 56 and the belt 58 are pressed.
If the gap between them is not greater than the thickness of one punched blank 54,
In the space 65, as shown by a broken line in FIG. 20, escape deformation in the laminating direction is allowed, and biting between the doctor 56 and the belt 58 is prevented.

The prevention of the biting does not cause a problem that the punched blank 54 is damaged, turned up, and the feeding is not smooth.

Next, the operation of the pre-feeder 1 will be described. The operation of the following pre-feeder 1 can be controlled by a sequence controller (not shown).

First, the laminate 53 is placed on the feeding conveyor 6. This mounting is performed manually by an operator, for example. At this time, it is assumed that the punched blanks 54 are stacked with the printing surface facing upward. Then, the stack 53 is transferred to the elevating conveyor 4 by the feeding conveyor 6.

Next, the lifting conveyor 4 is raised. At this time, as shown in FIG. 9, the reversing device 3 is located above the elevating conveyor 4, and the pair of left and right guides 10, 11 is located at a position where the facing distance is extended. Guide 1
The mounting bodies 32 and 33 fixed to 0 and 11 are in the lower position,
The mounts 30, 31 whose positions can be changed are set to the upper position.

When the lifting conveyor 4 is lifted from this state, as shown in FIG.
The stacked body 53 is carried in between the opposing surfaces.

Next, as shown in FIG.
11 is set to a reduced position, and both guides 10, 1
1 is brought into contact with the left and right side surfaces of the laminate 53. At this time, the placing bodies 32 and 33 located below are located below the stacked body 53, and the lifting conveyor 4 is located between the placing bodies 32 and 33.

Next, when the lifting conveyor 4 is lowered, the stacked body 53 is placed on the mounting bodies 32 and 33 as shown in FIG.

Next, the mounting bodies 30, 31 located on the upper side
Is swung by the extension of the fluid pressure cylinders 42 and 43, and the position of the two guides 10 and 11 is changed from the outside in the facing direction to the inside in the facing direction. Thereby, the mounting bodies 30 and 31 are pressed against the upper surface of the stacked body 53 as shown in FIG.

At this time, as shown in FIG. 6 and FIG.
3 is urged to press the upper surface. This allows
Even if there is a difference in the number of punched blanks 54 constituting the stacked body 53, the mounting bodies 30, 31 are in contact with the upper surface of the stacked body 53. That is, even when the number of blanks 54 is small as shown in FIG. 6 or when the number of blanks 54 is large as shown in FIG. Touch

Thereafter, as shown in FIG. 14, both guides 10, 11 are turned upside down in the direction indicated by the arrow in the figure around the longitudinal axis. For this reversal, the motor 70 of the belt wrapping transmission mechanism 71 is driven. Guide 1
In order to exactly flip 0 and 11 180 degrees, support 9
A pair of stoppers 75 and 76 are attached to the connecting member 14, and a stopper receiver 77 is attached to the guide 21. This stopper receiver 77 is the stopper 7
By contacting the stopper 5 or the stopper 76, the positions of the guides 10, 11 after rotation are accurately determined.

When the guides 10 and 11 are turned around the center in the front-rear direction, the stacked body 53 is placed on the placement bodies 30 and 31 displaced downward from above.

Next, as shown by the imaginary line in FIG. 5, the support 9 is moved forward by the hydraulic cylinder 17, and the reversing device 3 is located above the delivery device 5.

At this position, as shown in FIG. 15, the mounting bodies 30 and 31 on which the stacked body 53 is mounted are moved outward by the contraction of the fluid pressure cylinders 42 and 43 between the guides 10 and 11 in the facing direction. Is displaced. Thereby, the stacked body 53 falls, is carried out of the reversing device 3, and is mounted on the upper surface of the stacked body 53 already mounted on the belt conveyor 55 of the feeding device 5.

When the laminated body 53 falls from the space between the two guides 10 and 11 facing each other, the two guides 10 and 11
Of the two guides 1
It falls while being guided by 0 and 11, and the laminate 5
3 is prevented from collapsing upon falling.

Further, since the mounting bodies 30 and 31 are rollers rotatable about the longitudinal axis, the mounting bodies 30 and 31
Rolls with respect to the laminated body 53 when is displaced outward from the inside in the opposing direction of the two guides 10 and 11. Thus, the mounting bodies 30 and 31 do not damage the blank blank 54.
In particular, in this embodiment, the mounting bodies 30 and 31 are
Since the printed surface is in contact with the printed surface of No. 4, the printed surface is not damaged, which is preferable in preventing the product value from being impaired.

In this embodiment, the laminated body 53 placed on the belt conveyor 52 of the feeding device 5 is mounted on the frame 2.
Photoelectric switches 80 and 81 for detecting the height of the object are attached. Thereby, when a certain number of blanks 54 are sent out from the feeding device 5 and the number of the stacked bodies 53 is reduced, a signal for supplying the stacked body 53 to the feeding device 5 from the reversing device 3 can be transmitted. It has been.

When the laminated body 53 is dropped from between the two guides 10 and 11, the facing distance between the two guides 10 and 11 is increased as shown in FIG. It moves backward from the cylinder 17. At this time, since the two guides 10 and 11 are separated from the side surface of the stacked body 53, it is possible to prevent the stacked body 5 from being broken during the movement.

Next, as shown in FIG.
11 is turned upside down in the direction indicated by the arrow in the figure around the longitudinal axis, whereby the stacked body 53 is again brought into a state where it can be carried between the two guides 10 and 11, as shown in FIG. At this time, since the facing distance between the two guides 10 and 11 is enlarged, it is easy to carry the stacked body 53 into the space between the two guides 10 and 11 facing each other.

The present invention is not limited to the above embodiment.

For example, in the above-described embodiment, the laminated body 53 of punched blanks for paper containers is shown as the laminated body. However, the present invention is not limited to this. The present invention can be applied as long as
