Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for feeding a sheet-like article from a stack of sheet-like articles, such as paperboard paper and punched blanks for paperboard, for example.

(Prior Art) For example, punched blanks, which are printed by a printing punching machine and punched into a predetermined shape, are temporarily stacked to form a laminated body, and then sent to a sacks machine to be formed into a paper container.

When punching blanks from the laminate into a suck machine, it is necessary to feed blanks one by one.

However, the punched blanks that are stacked cannot be easily delivered one by one in close contact with each other.

In some cases, the laminate is loosened by hand to make it easier to send out one sheet at a time.However, a laminated body with a large number of punched blanks is difficult to loosen manually by heavy weight. is there.

Therefore, conventionally, as shown in FIG.
A belt conveyor on which a stacked body 202 in which 1 is stacked up and down is placed
A feeding device including a 203 and a doctor 204 in contact with the laminated body 202 at the front side in the feeding direction (the direction of arrow A in the drawing) of the belt conveyor 203 has been used.

As a result, the punching blanks 201 are fed from the upper and lower positions of the doctor 204 and the belt conveyor 203 so that the punching blanks 201 on the lower side are shifted forward in the feeding direction so that the blanking blanks 201 are located on the front side in the feeding direction. I was

In this way, by sending the blanks 201 once shifted from each other, air is introduced between the blanks 201 to release the close contact state, and the blanks 201 to the suck machine one by one. This makes it possible to easily feed the garbage.

(Problems to be Solved by the Invention) In the conventional feeding device, the belt conveyor 203 is used.
Blank 201 may be bitten between the upper and lower sides of the doctor 204 and the doctor 204.

Then, the surface of the punched blank 201 is pressed by the doctor 204 to cause scratches or dents, or
It is said that the punching blank 201 cannot pass between the upper and lower sides of the belt conveyor 203 and the doctor 204, buckling occurs and is turned up and damaged, and the product value is lost, and thus smooth feeding is hindered. There was a problem.

(Means for Solving the Problems) It is an object of the present invention to provide an apparatus for delivering a sheet-like article from a laminate, which can solve the above-described problems of the related art.

The features of the present invention include a conveyor in contact with one side in the stacking direction of the stacked body of sheet-like articles, and a doctor in contact with the front side in the delivery direction of the stacked body, and a sheet-shaped article is provided between the doctor and the conveyor. In the apparatus for feeding the articles in a state in which the sheet-like articles on the one side in the stacking direction are shifted toward the front in the sending direction, the space in which the sending-out front side of the sheet-like articles on the one side in the stacking direction of the laminate can move in the stacking direction, The feed direction of the conveyor is at a point on the front side in the feed direction of the laminated body so as to be formed at a position behind the doctor in the feed direction, and is set in a direction away from the stacked body in the stacking direction as approaching the doctor. .

(Operation) First, in the conventional feeding device shown in FIG. 9, a blank is punched from between the doctor 204 and the belt conveyor 203.
The following operation is capable of delivering the superposed sheets 201 so as to be shifted from each other in the delivery direction so that the lower punched blank 201 is located on the front side in the delivery direction.

Now, from above and below the doctor 204 and the belt conveyor 203, it is assumed that the punching blanks 201 have already been superposed and fed in a state shifted from each other in the feeding direction (note that, at the beginning of the feeding start, As the blanks 201 are sent out in a state shifted from each other in the sending direction,
The interval between the doctor 204 and the belt conveyor 203 is adjusted by moving the doctor 204 up and down. The vertical dimension of the polymer of the punching blank 201 sent out from above and below the doctor 204 and the belt conveyor 203 corresponds to the amount of the shift because the punching blanks 201 are shifted from each other in the feeding direction. The maximum dimension is obtained at every interval, and the distance between the maximum dimensions becomes smaller toward the rear in the feeding direction.

Therefore, the gap between the lower surface of the doctor 204 and the upper surface of the polymer of the punching blank 201 sent out from above and below the doctor 204 and the belt conveyor 203 gradually changes.

On the other hand, the rear part 201a of the lowermost layer of the punched blank 201-1 in the feed direction in the stack 202 is in contact with the belt conveyor 203, and the rear part 201a in the feed direction is in contact with the belt conveyor 203.
The frictional force in the feeding direction acting between the blanks 203 is larger than the frictional force in the feeding direction acting between the blanks 201. Therefore, the punch blank 201-1 of the lowermost layer
Is pushed in the feeding direction by the belt conveyor 203.

And, the punch blank 201-1 of the lowermost layer is
When the gap between the lower surface of 04 and the upper surface of the polymer of the punching blank 201 being sent out from above and below the doctor 204 and the belt conveyor 203 is smaller than the size that one punching blank 201 can pass, The delivery is regulated by the doctor 204, and when the gap becomes larger than a dimension that allows one punched blank 201 to pass, the blank is delivered from above and below the doctor 204 and the belt conveyor 203.

Next, when the blanking blank 201-1 which was the lowermost layer moves in the feeding direction, the second blanking blank from the lowermost layer is formed.
201-2 becomes the lowermost blanking blank 201-1,
The rear part 201a in the feeding direction is the belt conveyor 203.
And the above operation is repeated.

As a result, the lower punched blanks 201 are located on the front side in the feeding direction, and are sent out while being shifted from each other in the feeding direction.

In the above-described conventional delivery device, the punched blank 201-1 of the lowermost layer of the laminate 202 is pushed in the delivery direction by the belt conveyor 203, and the front side in the delivery direction is pushed down by the weight of the laminate 202. Have been.

For this reason, the front end of the lowermost blanking blank 201-1 in the feeding direction is always pushed between the belt conveyor 203 and the doctor 204, and there is no other place to escape.

Then, the gap between the lower surface of the doctor 204 and the upper surface of the polymer of the punching blank 201 being sent out from above and below the doctor 204 and the belt conveyor 203 is larger than the dimension that one punching blank 201 can pass. At the point before the enlargement, the front end of the lowermost blank blank 201-1 in the feeding direction bites between the belt conveyor 203 and the doctor 204 due to the deformation of the blank 201 itself or the elastic deformation of the belt conveyor 203. Will be.

Due to the bite, punch blank 201 became doctor 204
, Causing scratches or dents on the surface.
In addition, due to the biting, the punch blank 201 is jammed between the belt conveyor 203 and the doctor 204, and the jammed state is pushed in the feeding direction by the belt conveyor 203, so that buckling occurs. I will.

In contrast to the conventional feeding device as described above, according to the feeding device according to the present invention, a space is formed at a position behind the doctor in the feeding direction, in which one side in the stacking direction and the front side in the feeding direction of the stacked body can move in the stacking direction. I have.

Thereby, the sheet-like article on one side in the most stacking direction is
Even if the front side in the feeding direction is pushed by the conveyor and pushed between the doctor and the conveyor, if the gap therebetween is not large with respect to the thickness of one sheet-shaped article, the space is bent in the stacking direction due to the presence of the space. It does not deform and bites between the doctor and the conveyor. That is, by allowing the space to allow the front side of the sheet-shaped article in the stacking direction to be deformed so as to escape in the stacking direction, the sheet-shaped article bites between the doctor and the conveyor. Is prevented.

(Example) Hereinafter, an example of the present invention is described with reference to drawings.

FIG. 5 shows a pre-feeder 3 for feeding a block-shaped laminated body 2 in which punching blanks 1 for paper containers are vertically stacked to a sack machine for forming paper containers.

The blank 1 is printed by a non-illustrated printing punching machine and punched into a predetermined shape. The punched blanks 1 are stacked with the printing surface facing down to form a laminate 2.

The pre-feeder 3 releases the punched blanks 1 constituting the laminate 2 and transports the blanks 1 to the suck machine.
Are prevented from being fed into the suck machine in a close contact state.

The pre-feeder 3 includes a frame 4, a carry-in conveyor 5, a lifting conveyor 6, a transport device 7, a delivery device 8, a delivery conveyor 9, an auxiliary conveyor 18, and a stock conveyor 11.

Then, a feeder 110 of the suck machine is arranged on the exit side of the delivery conveyor 9. The feeder 110 includes a sack machine belt 111 and a hopper 112 above the sack machine belt 111.

The carry-in conveyor 5 is a belt conveyor that sends the stack 2 to the elevating conveyor 6.

The elevating conveyor 6 is a belt conveyor that raises and lowers the stacked body 2 carried in from the carry-in conveyor 5 or the stock conveyor 11 and sends the stacked body 2 to the transport device 7.

The transfer device 7 drops and conveys the stacked body 2 sent from the lifting conveyor 6 to the sending device 8.

Then, the feeding device 8 superimposes the punched blanks 1 from the laminated body 2 so as to be shifted from each other in the feeding direction such that the lowermost blanking blank 1 is located on the front side in the feeding direction (left side in the drawing). It is sent to the sending conveyor 9 in the state.

The delivery conveyor 9 inserts the punched blanks 1 sent from the delivery device 8 and carries the blanks 1 into the suck machine feeder 110.

And the hopper 112 of the suck machine feeder 110
, The punched blank 1 unloaded from the delivery conveyor 9
Is supplied, and the blank 1 in the hopper 112 is
By the rotation of the sack machine belt 111, the sack machine belt 111 is supplied one by one to the sack machine body (not shown).

The stock conveyor 11 temporarily stocks the stacked body 2 carried in from the carry-in conveyor 5 via the auxiliary conveyor 18.

As shown in FIGS. 1 to 4, the delivery device 8 includes a belt conveyor 19 that contacts the lower side of the laminate 2 and a rectangular plate-shaped doctor 20 that contacts the front side of the laminate 2 in the delivery direction. ing.

The belt conveyor 19 includes a drive shaft 22 attached to the frame 4 via a bracket 25 and driven by a motor 21, a driven shaft 23 attached to the frame 4 via a bracket 26, and the drive shaft 22 and the driven shaft 23. And a plurality of belts 24 wound therearound.

The belt 24 is capable of changing its position in the axial direction of the drive shaft 22, and is capable of transporting the laminate 2 having various shapes and sizes. The coefficient of friction of the outer peripheral surface of the belt 24 is
The frictional force in the feeding direction acting between the belt 24 and the blank 1 is set to be larger than the frictional force in the feeding direction acting between the blanks 1.

In the present embodiment, a pair of the doctors 20 are provided, and the doctors 20 are attached to the frame 4 via a positioning means (not shown) in a vertical direction, a feeding direction, and a horizontal direction orthogonal to the feeding direction. Thereby, the doctor 20 can come into contact with the front side in the feeding direction of the laminated body 2 having various sizes and shapes, and the vertical interval with the belt conveyor 19 can be adjusted.

Further, four guide rods 27 are mounted on the frame 4 in a lateral direction orthogonal to the feeding direction by a set screw 28 so as to be adjustable in position. Each guide rod 27
A bolt 29 having a vertical axis is attached via a set screw 30 and a pedestal 31 so that the position can be adjusted in the feeding direction. Each bolt 29 has a mounting block 32 and a nut 33
It is mounted so that the position can be adjusted in the vertical direction via the.

The positioning pieces 34 of the laminated body 2 are mounted on the pair of mounting blocks 32 via bolts 35 and nuts 36, respectively. The pair of positioning pieces 34 come into contact with the respective side surfaces orthogonal to the feeding direction of the laminated body 2, so that the positioning in the lateral direction perpendicular to the feeding direction of the laminated body 2 is performed.

A pressing belt mechanism 37 is attached to each of the pair of attachment blocks 32.

The pressing belt mechanism 37 includes a base plate 38, a drive pulley 39 attached to the base plate 38, and a pair of upper and lower driven pulleys 42, the drive pulley 39, a belt 40 wound around the driven pulley 42, and a drive The driving motor 41 drives the pulley 39.

The belt 40 is located on the rear side in the sending direction of the laminated body 2 and is in contact with a lower portion of the side surface along the sending direction, and is driven to rotate in the direction of the arrow in FIG. Due to the rotation of the belt 40, the rear side in the feeding direction of the laminated body 2 in contact with the belt 40 is pushed down, and the rear portion 1a in the feeding direction of the lowermost blank 1 is placed on the upper surface of the belt 24 of the belt conveyor 19. Pressing is possible.

Then, as shown in FIG.
The feeding direction is a direction in which the stacked body 2 placed on the belt conveyor 19 is located forward of the feeding direction, and is separated from the stacked body 2 downward in the stacking direction as it approaches the doctor 20.

That is, on the inner peripheral side of the belt 24 wound around the drive shaft 22 and the driven shaft 23 of the vent conveyor 19, an intermediate roller 43 that idles around an axis parallel to the drive shaft 22 is provided. Is configured to push up the belt 24 on the front side in the feed direction from the position of the center of gravity of the stacked body 2 placed on the belt 24. The intermediate roller 43 is mounted on the frame 4 via a positioning means (not shown) so that the position of the intermediate roller 43 can be adjusted in the feeding direction and the vertical stacking direction.

Thereby, as shown by the arrow in FIG. 1, the feed direction of the belt conveyor 19 is along the bottom surface of the laminated body 2 on the rear side in the feed direction from the intermediate roller 43, and on the forward side in the feed direction from the intermediate roller 43, As it approaches the doctor 20, it separates downward from the laminate 2.

The specific position in the feeding direction and the position in the vertical direction of the intermediate roller 43 are determined by the size, shape,
Determined appropriately according to the material and the like.

 Next, the operation of the delivery device 8 will be described.

Now, it is assumed that the blanks 1 are already being fed from the upper and lower portions of the doctor 20 and the belt conveyor 19 in a state of being shifted from each other in the feeding direction (at the beginning of the feeding, The positions of the doctor 20 and the intermediate roller 43 are adjusted so that the blanks 1 are fed in a state of being shifted from each other in the feeding direction.) The blanks fed from above and below the doctor 20 and the belt conveyor 19. The top and bottom dimensions of polymer 1 are
Since the blanks 1 are displaced from each other in the feeding direction, the maximum size is obtained at intervals corresponding to the shift amount, and the distance between the maximum sizes becomes smaller toward the rear in the feeding direction.

Therefore, the gap between the lower surface of the doctor 20 and the upper surface of the polymer of the blank 1 that is fed from above and below the doctor 20 and the belt conveyor 19 changes gradually.

On the other hand, when the belt conveyor 19 is driven, the rearmost portion 1a of the lowermost layer of the laminated body 2 in the feeding direction of the punched blank 1-1 is moved.
Is in contact with the belt conveyor 19, and the friction force in the delivery direction acting between the rear portion 1a in the delivery direction and the belt conveyor 19 is larger than the friction force in the delivery direction acting between the blanking blanks 1. . Therefore, the blank blank 1-1 of the lowermost layer is pushed in the feeding direction by the belt conveyor 19.

According to the feeding device 8 according to the present invention, the feeding direction of the belt conveyor 19 is a position on the front side in the feeding direction of the stacked body 2, and the stacked body 2 is moved closer to the doctor 20.
From the bottom. As a result, a space 44 in which the front side of the punched blank 1 on the lower side of the laminated body 2 in the feeding direction can move up and down is formed at a position behind the doctor 20 in the feeding direction.

Then, the front side of the lowermost blanking blank 1-1 in the feeding direction is pushed in the feeding direction and pressed against the doctor, and is bent and deformed in the space 44 to be moved from the position shown by the imaginary line in FIG. It descends to the solid line position and tries to enter between the doctor 20 and the belt conveyor 19.

The lowermost blank blank 1-1 is a doctor 19
When the gap between the lower surface of the punching blank 1 and the upper surface of the polymer of the punching blank 1 being sent out from above and below the doctor 19 and the belt conveyor 20 is smaller than the size that one punching blank 1 can pass, the feeding is performed. When the gap is regulated and the gap becomes larger than the size that one punched blank 1 can pass, the blank is sent out from above and below the doctor 20 and the belt conveyor 19.

Next, when the punched blank 1-1, which was the lowermost layer, moves in the feeding direction, the second blanked blank 1 from the lowermost layer.
-2 is the newest blank blank 1-1, and the rear side portion 1a in the feeding direction comes into contact with the belt conveyor 19, and the above operation is repeated.

As a result, the lower blank 1 is positioned at the front side in the feeding direction, and is sent out in a state shifted from each other in the feeding direction.

According to the delivery device 8, even if the front side in the delivery direction of the punching blank 1-1 of the lowermost layer is pushed by the belt conveyor 19 and is pushed into between the doctor 20 and the belt conveyor 19, during that time, Is not larger than the thickness of one blank 1, the space 44
As shown by the broken lines in FIG. 1, escape deformation in the laminating direction is allowed, and biting between the doctor 20 and the belt conveyor 19 is prevented.

By preventing this biting, there is no problem that the blank 1 is damaged, turned up, or the feeding is not smooth.

The present invention is not limited to the above embodiment.

For example, as shown in FIG. 6, the surface on the rear side in the feed direction of the lower end of the doctor 20 is formed as an inclined surface 45 that is directed forward in the feed direction as it goes downward, thereby facilitating the delivery of the blank 1. You may try.

In this case, if the material of the blank 1 is a material having high flexibility, as shown in FIG. 6, not only the lowermost blank 1-1 but also a plurality of blanks above the blank 1-1. In some cases, the front side of the punching blank 1 in the feeding direction may be bent and deformed together. Even in this case, a space 44 is formed between the punched blank 1 that has been lowered together and the punched blank 1 above it. Due to the presence of this space 44, the punch blanks 1-1 of the lowermost layer are allowed to be deformed in the laminating direction together with the punch blanks 1 which have been gathered and lowered downward, so that the punch blanks 1
Biting between 20 and belt conveyor 19 is prevented.

Further, in the above embodiment, the belt conveyor 19 is arranged below the laminate 2 and the blank 1 is punched from below the laminate 2.
The present invention is applied to a feeding device that feeds the stack 2, but as shown in FIG. 7, the belt conveyor 19 is arranged above the stack 2, and the stack 2 is pressed against the belt conveyor 19 by the lifting table 46, The present invention may be applied to a delivery device 8 that delivers the blank 1 from above. In this case, the feeding direction of the belt conveyer 19 is a direction that is separated from the stacked body 2 upward in the stacking direction toward the doctor 20 on the front side (left side in the drawing) in the feeding direction of the stacked body 2.

The present invention is also applicable to a delivery device in which the laminating direction of the punched blanks is the horizontal direction, a belt conveyor is arranged on the side of the laminate, and the punched blanks are delivered from the sides of the laminate.

In addition, the present invention can be applied to an apparatus for feeding a sheet-like article other than a punched blank.

Further, instead of the belt conveyor, a sheet-like article may be sent out by, for example, a roller conveyor.

The feeding device 8 according to the present invention is suitable for feeding a blank blank 1 having flaps 47, 48, and 49 having a shape as shown in FIG.

That is, the flap 47 of the blank 1 shown in FIG.
And the flap 48 have edges 47a and 48a facing each other in the feeding direction (the direction of arrow A in the figure).

Further, the flap 47 and the flap 49 similarly have edges 47b and 49b facing each other in the feeding direction.

Then, the flaps 48 and 49 of the lower blank 1
Is warped and overlaps with the flap 47 of the upper blank 1 in the feeding direction, when the lower blank 1 is fed, the edges of the flaps 48, 49 of the lower blank 1 48a, 49b are caught and broken by the edges 47a, 47b of the flap 47 of the upper blank 1.

In order to prevent this, as shown by the phantom line in FIG. 2, at a slightly upper position between the doctor 20 and the belt conveyor 19,
A pressing rotary body 50 is provided in contact with the flaps 48, 49, and the rotary body 50 is driven to rotate in the direction of the arrow in FIG. 2 to push up the flaps 48, 49 of the lower blank 1 to punch the upper blank. It is conceivable to prevent the blank 1 from being caught by the flap 47.

At this time, in the conventional feeding device in which the space 44 is not formed, it is necessary to push down the flap against the tension of the belt of the belt conveyor, but it is hardly possible to push down because the belt tension is large.

On the other hand, according to the delivery device 8 according to the present invention,
The flaps 48, 49 can be easily pushed down by the existence of the space 44, and the punch blank 1 can be prevented from being damaged by the catch.

Further, in the above embodiment, when the pressing belt mechanism 37 is driven, the belt 40 pushes down the rear side in the feeding direction of the laminated body 2 so that the rear side portion 1a of the lowermost punched blank 1-1 in the feeding direction is belt-like. It can be pressed against the upper surface of the belt 24 of the conveyor 19.

As a result, the frictional force in the feeding direction acting between the rear side portion 1a of the lowermost blank blank 1 in the feeding direction and the belt conveyor 19 is positively increased. Belt conveyor 19 for blank 1
This is effective when the blank 1 is made of a material having a small coefficient of friction.

The operation of the pre-feeder 3 is controlled by a control device (not shown). Hereinafter, the operation of the pre-feeder 3 will be described.

First, the stack 2 is placed on the carry-in conveyor 5. At this time, the front ends in the transport direction of the stacked body 2 are aligned using the shutter 12 as a guide.

Next, the placement completion switch 94 is turned on. Then, the shutter 12 is lowered, and thereafter, the carry-in conveyor 5 and the elevating conveyor 6 are driven to rotate. Thereby, the stacked body 2 is transported and placed on the elevating conveyor 6.

Then, the front end of the stacked body 2 in the transport direction is a carry-in detection switch.
13, the carry-in conveyor 5 and the lifting conveyor 6 stop operating, and then the hoisting device 14
The hoist 15 raises the lifting conveyor 6.

The lifting of the lifting conveyor 6 is stopped by the detection of the lifting detection switch 16.

Next, the elevating conveyor 6 and the belt conveyor 71 of the transport device 7 are rotated by a timer for a certain period of time, and the laminate 2 is transported and placed on the transport device 7.

Next, the stacked body 2 is positioned above the delivery device 8 by the movement of the transport device 7 due to the extension of the cylinder 53.

Then, the stacked body 2 is moved by the falling mechanism (not shown) of the transfer device 7.
Is dropped and conveyed to the delivery device 8.

As a result, the punching blanks 1 are delivered from the laminate 2 by the delivery device 8 in a state where they are shifted from each other in the delivery direction and are superposed.

Then, the ejection blank 1 sent out from the delivery device 8 is supplied from the delivery conveyor 9 to the suck machine feeder 110.

The punched blank 1 sent out from the feeding device 8
Are stacked again in the hopper 112 of the sack machine feeder 110 to form a laminated body. Since the laminated body is in a loosened state with air between the blanks 1, each of the blanks 1 Is released, and the sack machine belt 111 can surely feed the sack machine one sheet at a time. At this time, in the hopper 112, the rear end of the blank 1 is supported by the support piece 113 so as not to come into contact with the suck machine belt 111. 1 is in contact with the front end. Thus, the blanks 1 in the hopper 112 are fed one by one without overlapping with the blanks in the upper layer.

Until the photoelectric switch 87 detects that the height of the stacked body 2 has fallen below a certain level, the elevating conveyor 6 stops at the upper layer position and waits.
The auxiliary conveyor 18 and the carry-in conveyor 5 are set at the same height.

In this state, when the stack 2 is placed on the carry-in conveyor 5 and the placement completion switch 94 is turned on, the carry-in conveyor 5 and the auxiliary conveyor 18 are driven to rotate after the shutter 12 descends, and the laminate 2 is conveyed to the auxiliary It is placed on the conveyor 18. When the carry-in detection switch 13 detects the stack 2, the stock conveyor 11 is driven to rotate, and the stack 2 is transported and placed on the stock conveyor 11. When the photoelectric switch 96 detects the rear end of the stack 2 in the transport direction, the stack 2 is entirely placed on the stock conveyor 11, and the stock conveyor 11 stops.

Further, in a state where the elevating conveyor 6 is on standby, the next stacked body 2 is placed on the conveyer 5 to be carried in, and a loading completion switch is placed.
When 94 is turned ON, similarly, the laminate 2 is a stock conveyor.
It is placed on 11.

In addition, the first in the transport direction of the stock conveyor 11 is
A stock detection switch 97 is provided, and a second stock detection switch 98 is provided on the side.

The first stock detection switch 97 is a stock conveyor.
The front end in the transport direction of the stacked body 2 placed on 11 is detected.

The second stock detection switch 98 is provided behind the first stock detection switch 97 in the conveyance direction at a distance determined based on the size of the stack 2 in the conveyance direction, and is disposed on the stock conveyor 11. 2 to detect the rear end in the transport direction.

When both the first stock detection switch 97 and the second stock detection switch 98 detect the stack 2, the control device determines that the stock conveyor 11 is in a full state where the stack 2 cannot be placed any more, and An interlock is provided so that the conveyor 18 does not operate. When the stack 2 is placed on the carry-in conveyor 5 and the loading completion switch 94 is turned on in this full state, the lift conveyor 6 and the auxiliary conveyor 18 are lowered after the standby state of the lift conveyor 6 is released, and the stacking is performed. The body 2 is transported from the lifting conveyor 6 to the transport device 7 like a front load.

Note that a drop prevention piece 99 of the laminated body 2 is provided in front of the first stock detection switch 97 in the transport direction.

The photoelectric switch 96 also serves as a count switch for counting the number of the stacked bodies 2 stocked on the stock conveyor 11, and stores the number of stocks in the control device.

Further, an interlock is provided so that the elevating conveyor 6 does not descend while the auxiliary conveyor 18 conveys the laminated body 2,
After the photoelectric switch 96 detects the rear end of the stack 2 in the transport direction, the lifting conveyor 6 and the auxiliary conveyor 18 can be lowered.

Then, the elevating conveyor 6 and the auxiliary conveyor 18 are lowered, the stack 2 is placed on the stock conveyor 11 (regardless of whether it is full), the loading completion switch 94 is not turned on, and the side of the loading conveyor 5 is When the photoelectric switch 100 provided on the side does not detect the stacked body 2, the stock conveyor 11 and the elevating conveyor 6 are driven to rotate in the opposite direction to the conveyance.
As a result, the stacked body 2 that is finally stocked is placed on the elevating conveyor 6, and when the front end of the stacked body 2 in the transport direction is detected by the carry-in detection switch 13, the elevating conveyor 6 is stopped. In addition, the second laminated stock 2
Is detected by the photoelectric switch 96, the stock conveyor 11 is stopped.

Then, the laminate 2 placed on the elevating conveyor 6 is transported to the transport device 7 in the same manner as described above. By repeating this, the stacked bodies 2 stocked on the stock conveyor 11 are sequentially conveyed. Then, when the stocked laminate 2 runs out, an alarm is issued by a buzzer or the like.

When the stack 2 is placed on the carry-in conveyor 5 and the loading completion switch 94 is turned on while the stack 2 is being unloaded from the stock conveyor 11, the stack 2 being unloaded is transferred to the transfer device 7 2 placed on the carry-in conveyor 5 after being transported
Is carried. Prior to the start of the unloading operation of the stack 2 from the stock conveyor 11, the transport of the stack 2 placed on the carry-in conveyor 5 is prioritized.

As described above, by vertically arranging the transport device 7, the delivery device 8, and the stock conveyor 11, the space in the vertical direction can be effectively used, and the device is suitable for a workplace where the horizontal space is limited. .

(Effect of the Invention) According to the feeding device according to the present invention, when feeding a sheet-shaped article from the laminate in a state shifted in the feeding direction, the sheet-shaped article can be prevented from biting between the doctor and the conveyor, It is possible to prevent the sheet-shaped article from being damaged or damaged by being turned up, and to smoothly feed the sheet-shaped article.
