Is shown in FIG. Conventionally, seaweed is supplied one after another and plastic
Wrapped in a backing film to form a bag-like sheet
As a method for continuously manufacturing sheets, Japanese Utility Model Laid-Open No. 6-53493 is used.
An example is shown in FIG. However, the manufacturing method of FIG.
The law is just a paper plan and the film is
The plastic film is bent into grooves by the former.
It is very difficult to place nori on the same pitch.
Has not been put to practical use. Not practical in the future
It is easily understood by those skilled in the art. At present, a continuous production apparatus for a bag-like sheet containing laver
Have more than a hundred units in operation, but nori pick-up
No application has been filed except for the
However, the outline of the configuration is explained below.
I do. Exterior film and two interior films fill one sheet

At the center between the moss, overlap the edges of the interior film
Excluding Nijo horizontal heat seal and Nijo horizontal heat
Horizontal cut between Tosir. Conventionally, the production of the above-mentioned bag sheet containing laver
The Nori pick-up device that has been adopted for the device is
No. 54-2743, Japanese Patent Publication No. 54-4148,
This is an invention device disclosed in Japanese Patent Publication No. 3-13134. This
These patent publications state that the nori pick-up device is accurate.
And the principle of picking up nori is not explained
Therefore, it will be described below. Nori is about 100 mm x about 190 mm long
It is square and 100 to 200 sheets are stacked, and the stacking state is broken
Be surrounded by a support frame. Support along the short side of laver
There are two pairs of opposing movable claws at the bottom of the side of the frame, under the support frame
Project 30-40mm below the opening of the nori
Support four points. The bottom of the laver is the suction beneath the support frame.
The draw box lifts the laver while sucking and instantly goes down
It is picked up by dropping and the suction box is
Vacuum function is provided by releasing suction during descent
Rolled into a conveyor belt
Another conveyor that moves out at high speed and then moves at high speed
Packaging that is transported in the lengthwise direction by Abelt and moves at low speed
It is transferred to the carry-in conveyor of the machine. About 9 suction boxes
It has a plane shape of 0mm x about 130mm and the area of nori
Approximately 3/4, leaning to one side, while performing suction,
Push up into the opening at a very high speed and
Move the seaweed 15-20mm from the rest position to the bottom
Adsorb seaweed and descend at high speed. The movable claw is a suction box
To raise the suction box to avoid interference with
Swings down quickly, and then the suction box
Suction box when adsorbing the bottom seaweed and descending at high speed
Swinging at high speed to avoid interference with
Supports the layered laver. Therefore, under the instant of the movable claw
Due to the rocking motion, all the laver is contained in the support frame and gravity
Attempts to start falling by action, but still inertia works
The suction box is very fast at 15-2
As we push up 0mm, all nori is pushed up
You. The bottom laver is pushed up by the suction box
The suction box comes in close contact, and the suction box
After that, it descends instantly, much faster than the gravity fall speed
Then, it is separated from the laver in the second and subsequent layers from the bottom
You. The movable claw is fast at the same time as the suction box descends
The second and subsequent laver that rises and oscillates and then descends later are still
Reach the support position before reaching the position, the second and subsequent
Supports nori. Nori is mesh-like and breathable
So the movable suction box has the first seaweed torn
In rare cases, such as when the first two sheets of laver from the bottom
May be sucked at the same time. Therefore, the suction box
The cousin sucks the both ends of the seaweed in the long direction and draws it downward.
It has a shape that can be bent and held, and it corresponds to the first nori
Suction power is strong, and the suction power for the second laver is weak
So, only the first laver curves both edges in the long direction
Sucked and picked up securely, the second nori is long
Picked up with both edges of the direction extending horizontally
To try. At that time, the movable claw is
As high as possible without lowering the suction box as long as it does not interfere
Swing fast and pull the second laver from the bottom laver
Peel off and fall further late The third and subsequent laver from the bottom
Support along with. At the descent stop position of the suction box
And a roll having the above-mentioned vacuum function.
The surface of the belt is almost the same. Suction box available
By releasing the suction on the way down after rubbing with the moving nail,
The first sea picked up by the suction box
Moss falls almost without leaving the top of the suction box,
Sucked with a belt wound on a roll with vacuum function
Is sent out at high speed in the short direction, and then moves at high speed
It is transported in the longitudinal direction by another conveyor belt, and
Transferred to the carry-in conveyor of the packaging machine via the intermediate conveyor
You. [0007] Nori has a layered shape due to its complex surface.
In the state, the bottom seaweed can be pulled out by contacting the compaction roll
Is completely impossible. In addition, seaweed is breathable,
Suction the bottom layer of seaweed with a vacuum pad and pull
It is impossible at all. How to pick up above
In addition to the method, to pick up the seaweed one by one
Can not. As you can see from the above explanation,
It is important to ensure that only nori is picked up.
There are two things. One is a movable claw that moves the laver
When supported from below, the first laver and the second sea from the bottom
The weight of nori is the number of seaweeds minus one from the total number
Acts as an adhesive force, so push up the suction box
The seaweed at the bottom from the bottom
The second layer of seaweed is pushed up to maintain the adhesion.
Is to eliminate them. The second is the suction box
Kuss simultaneously sucks the first and second nori from the bottom
Because it ’s not impossible to pick it up,
Only the first seaweed is curved by bending both longitudinal edges
Then pull the second laver from the first laver with movable claw
Peeling off. The principle of picking up the above seaweed is
There is no indication or suggestion in the gazette, but it is true. Description of statement
Does not describe or understand the principle of pickup,
Only the connection of the mechanical elements is described. Of course from the above
As a result, the Nori pick-up device is
There is also an invention of Japanese Patent Publication No.
It has not been put to practical use and other nori pick-up
Nothing was adopted for the installation. [0008] [Problems to be solved by the invention]
Tokuho Sho5, the only practical pickup device
No. 4-2743, Japanese Patent Publication No. 54-4148,
The invention disclosed in Japanese Patent Publication No. Hei 3-13134 has the following problems.
There is a point. The maximum number of pickups per minute is 120
is there. Considering the conventional equipment, 120 nori per minute
To pack the seaweed, pick-up time per piece
Is 0.5 seconds. Then, due to the shape of the cam groove,
When the box stops at the lowered position and the suction box
It is considered that the time for lifting, adsorbing seaweed and descending is almost the same
And 0.25 seconds each. 0.25 seconds
The suction box moves up, adsorbs laver and descends
Depending on the product, the speed of picking up the seaweed is the current machine
At the appropriate maximum speed limit. However
The user can get 150 to 200 sheets per minute
We hope that we can pick up nori. Conventional
This device uses the suction box to pick up the laver
Suck with a conveyor belt and send the laver at high speed in the short direction
By picking up, 120 pickups per minute
Has finally been realized. However, the packaging speed has been increased.
To a suction box and a roll with vacuum function
The length of the seaweed is changed by changing the arrangement of the wound conveyor belt by 90 degrees.
If you try to change the design in the direction, there will be unpractical problems.
Cheating. The reason will be described below. First, the suction box
A half of the width of the nori at the center and suction the entire length in the longitudinal direction,
Dividing the conveyor belt with vacuum function into two
Arrange the suction box and lower the suction box.
Consider the case where the upper surface of the
I can. Nori is 190mm long and bag is 223mm long
And the difference is 33 mm. Pick up by suction box
Nori is moved from the top of the suction box
The distance is about 190 mm, and the
At the moment the conveyor belt transported nori about 190 mm,
The time for the pull box to pick up the next nori
Completed when the bare belt has moved the previous laver 33 mm
Must be completed. Pick up 120 sheets per minute
0.5 seconds when the suction box has stopped descending
× (190 ÷ 223) = 0.426 seconds,
It takes 0.5 seconds for the cousin to push up, adsorb seaweed and descend
× (33 ÷ 223) = must be within 0.074 seconds
You. In addition, the conveyor belt sucks seaweed.
It takes a very short time to start the transfer by using. Obedience
It is not practical. Next, in the suction box
Conveyor belt that suctions half the length and has a vacuum function
To the other half of the nori, and use the suction box
Of the conveyor belt
Consider the case where Conveyor bell with vacuum function
As soon as he transported about 95 mm of seaweed, the suction box
You can pick up the next nori. 120 per minute
To pick up pieces, the conveyor belt removes nori
By the time it moves 33 mm + 95 mm, the suction box is
Need to complete the next nori pick-up
You. Conveyor belt with vacuum function reduces seaweed
As soon as 95 mm has been transferred, the suction box
If the suction box starts, the suction box moves down
The stopped time is 0.5 seconds × (95 ÷ 223) = 0.
213 seconds, suction box thrusts up and absorbs seaweed
And the time of descent is 0.5 seconds × (128 ÷ 223) = 0.
287 seconds, and the time allocation is sufficient. However
A half of the length of the laver with the suction box
Even if you try to remove the nori from the movable claw on the conveyor side
There is a problem of not achieving the pickup that the part does not come off,
Therefore, it is not practical. To solve this problem further
The quest to pursue is the creation of innovative technological ideas.
Beyond the scope of the related art.
I will not touch it anymore. Vacuum the laver picked up by the suction box
Suction with a belt wrapped around a functional roll
High-speed delivery to the conveyor for loading the laver packaging machine.

Since a feeding device for sheet-like objects is installed,
The width of the device is extremely large. The seaweed picked up by the suction box is raised in the short direction.
Conveyor that transports seaweed in the longitudinal direction because it is sent at high speed
There are three conveyors, high speed, medium speed, and low speed.
A. The first high-speed conveyor, for example, after
The mounting pitch of the push claw is 446 mm and the transfer speed
The degree is twice that of the low-speed conveyor. Low speed conveyor packaging
The conveyor for loading the machine.
Switch is equal to the length of the bag-like sheet and is 223 mm,
The seaweed with a length of about 190 mm is boosted and transferred. this
As shown in the figure, the conveyor that transports the seaweed in the longitudinal direction is long (about
3m), the overall length of the device is extremely large. The present invention has been made in view of the above points.
So, pick up the seaweed and send it out in the long direction
It is sent to the carry-in conveyor of the laver packaging machine without changing the direction.
It can be handed over, and the appropriate maximum pick-up of nori
The number of sheets, especially the number of bags of laver
It can supply about 200 sheets per minute,
Since there is no need to install the side at the upstream end of the bear,
The width of the device can be reduced, and the loading
Conveyor can be singly and in the short direction.

mm, the next push-up is performed. concrete
A calculation example will be described. A place to pick up 150 sheets of seaweed per minute
If The pickup time per sheet is 60 seconds ÷ 150 sheets =
0.4 seconds / sheet, and picked up nori K
The time required to transfer about 48 mm is 0.4 seconds × (4
8 mm / 223 mm) ≒ 0.086 seconds. Therefore,
The suction box 5 is moved in a simple vibration without stopping to transfer the laver.
The slight distance to move backward in the feed direction is 0.0 round trip time.
What is necessary is just to design so that 86 seconds may pass. Therefore, the suction
0.086 seconds after the box 5 picks up the laver
Time left after completing the next pickup
Is 0.4 seconds−0.086 seconds ≒ 0.314 seconds.
During this time, the conventional device uses 120 nori per minute.
Picks per sheet when picking up
The up time is 0.5 seconds / sheet, and the suction box is set at 0.
Stop for 25 seconds and the suction box will hang in the remaining 0.25 seconds.
Compared to the configuration of raising and lowering
If it is, it is a sufficiently large value. A place to pick up 200 sheets of seaweed per minute
If Pickup time per sheet is 60 seconds / 200 sheets =
0.3 seconds / sheet, and the seaweed K picked up
The time required to transfer about 48 mm is 0.3 seconds × (4
8 mm / 223 mm) ≒ 0.065 seconds. Suction box
0.065 seconds after Kusu 5 picks up the laver
After that, the time required to complete the next pickup is
0.3 seconds−0.065 seconds ≒ 0.235 seconds, therefore, 0.
235 seconds can be secured. Even in this time, the conventional device still
When picking up 120 sheets of laver
Slightly longer than the pickup time per sheet
