DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for feeding and feeding sheets such as laver and handmade Japanese paper one by one.

[0002]

2. Description of the Related Art A conventional supply device of this type is disclosed in, for example, JP-A-2000-109228.
A sheet supply device is known. FIG. 24 is a diagram showing a configuration of a conventional device disclosed in the publication.

In the sheet supply apparatus shown in FIG. 1, sheets 100 are stacked and stored in a stocker 110, and the sheets 100 are taken out one by one from a bottom of the stocker 110 by a feeding roller 120. It has a configuration.

The feeding roller 120 is rotatable in the front-rear direction (left-right direction in the drawing) along the bottom surface of the stocker 110, and a small circular suction nozzle 121 is formed on the peripheral surface thereof. When removing the sheet material 100 from the stocker 110, the feeding roller 120 is moved to the sheet material 10
0 to the rear end position (the right end position in the drawing), the suction nozzle 121 sucks the rear end of the sheet-like material 100 in the lowermost layer in the stocker 110, and moves the feeding roller 120 forward (in the drawing). The sheet-like material 100 is wound around the peripheral surface of the feeding roller 120 while rotating (leftward).

[0005] The sheet-like material 100 taken out by the feed-out roller 120 is transferred to the conveyor 140 via the conveyor drum 130 and conveyed one by one in the downstream direction.

[0006]

The above-mentioned conventional device is,
In order to transfer the sheet-like material fed by the feed-out roller 120 to the transporting conveyor 140, the transporting drum 130 is interposed therebetween, so that there is a problem in that the structure of the product becomes expensive.

Moreover, in such a conventional structure, in order to smoothly transfer the sheet-like material 100, the sheet-like material 100 is transferred from the feeding roller 120 to the transport drum 130.
At the time of delivery, it is necessary to control the peripheral speed of the transport drum 130 so as to match the transport timing of the sheet-like material 100 by the feeding roller 120. Further, the transport drum 1
When the sheet-like material 100 is transferred from the transport conveyor 30 to the transport conveyor 140, the peripheral speed of the transport drum 130 needs to be adjusted to the movement timing of the transport conveyor 140, and the timing control thereof is complicated.

As the sheet-like material 100 supplied by the above-mentioned conventional sheet-like material supply apparatus, there are seaweed and handmade Japanese paper dried into a sheet. In the case of this type of sheet material 100, for example, in the case of laver, small holes 201 may be scattered in several places on the surface of the laver 200 as shown in FIG. Further, as shown in FIG. 26, in the handmade Japanese paper 300, there may be a portion called a spot 301 having a coarse fiber density and forming fine gaps.

The small holes 201 and the spots 301 are
Since the gap is formed in the sheet-like material 100, a small-hole-shaped suction nozzle 121 formed in the feeding roller 120 is formed.
Is the seaweed 20 taken out from the bottom of the stocker 110
When the small hole 201 and the small spot 301 of the handmade Japanese paper 300 overlap, the gap (the small hole 201 and the small spot 30) is overlapped.
1) Leakage of air occurs through, and the sheet-like material (seaweed 200 or handmade Japanese paper 300) cannot be reliably adsorbed, or
The second sheet-like material is also attracted through the gap, and two sheets are taken out at the same time. As a result, there is a possibility that the taking-out mistake of the sheet-like material 100 may be caused.

In a conventional sheet-like material supply apparatus,
The storage space for the sheet-like material 100 is surrounded by the support plate 111 to which the stocker 110 is fixed. For this reason,
Sheet-like material 1 taken out from the lowermost surface of stocker 110
When the leading end of the sheet 100 is in contact with the support plate 111 (i.e., the end that is first sucked by the feeding roller 120), the sheet 100 is caught with the contact resistance. There was a risk of making mistakes.

Further, in the laver 200 and the handmade Japanese paper 300, there are many individual differences in the molding size.
10, each sheet-like material 100
(Nori 200 and handmade Japanese paper 300) often have irregular end positions. As described above, when the feeding roller 120 is at a certain position (the front end of the stocker 110) and the end of the sheet-like material 100 in the lowermost layer is deviated from this position to attract the sheet-like material 100 In addition, the lowermost sheet-shaped material 100 may not be properly taken out by erroneously adsorbing the sheet-shaped material 100 stacked thereon, and as a result, there is a possibility that the sheet-shaped material 100 may be taken out incorrectly. was there.

Further, nori 200 and handmade Japanese paper 30
Sheet-like material 10 whose surface and edges are rough and rough like 0
0, when the lowermost sheet-like material 100 is pulled out from the stocker 110, the frictional force between the lowermost sheet-like material 100 and the second sheet-like material 100 stacked thereon is the suction force of the feeding roller 120. As a result, there is a possibility that slippage may occur between the feed roller 120 and the feed roller 120, thereby causing a take-out error.

The present invention has been made in view of such circumstances, and a first object of the present invention is to provide a sheet-like material supply device having a simple structure and easy control. Also,
A second object of the present invention is to prevent a sheet-like object from being taken out incorrectly and to supply a sheet-like object smoothly and reliably.

[0014]

In order to attain the above object, according to the present invention, there is provided a stocker capable of stacking and holding a plurality of sheets and removing the sheets from the bottom, Suction holes are formed at a plurality of locations on the peripheral surface, and the sheet-like material held in the lowermost layer in the stocker is sucked by the suction holes, and is rotationally moved from the front end to the rear end along the bottom surface of the stocker. A feeding roller that winds and feeds the sheet-like material, a suction conveyor that sucks and pulls out the sheet-like material fed from the stocker by the feed-out roller, and a sheet-like material drawn out of the stocker by the suction conveyor. Transport means for transporting in the direction.

According to the present invention, the sheet-like material fed by the feed-out roller is directly delivered to the suction conveyor. Therefore, the structure of the apparatus is simplified, and when the sheet-like material is delivered, the sheet-feeding material is connected to the suction roller. Since only the operation timing of the suction belt needs to be considered, the control becomes easy.

Here, if the suction conveyor is provided with means for releasing the suction state of the sheet-like material before transferring the sheet-like material to the conveying means (Claim 2), the means may be used for the sheet-like material. Just release the adsorption state of the object,
The sheet can be smoothly delivered to the transporting means.

According to a third aspect of the present invention, there is provided a stocker for stacking and holding a plurality of sheet-like objects, and having a plurality of suction holes formed at a plurality of positions on a peripheral surface thereof. A delivery roller that sucks the sheet-like material held in the lowermost layer in the stocker by the suction holes, and rotates along the bottom surface of the stocker from the front end to the rear end to wind and feed the sheet-like material. A suction conveyor that sucks and pulls out the sheet-like material fed from the stocker by the feed-out roller, and a conveying unit that conveys the sheet-like material drawn from the stocker by the suction conveyor in a downstream direction. A supply device for a shape-like material, wherein the suction conveyor and the transporting means are particularly configured as follows.

That is, the suction conveyor has a timing belt for forming a drawing path of the sheet-like material, an adsorption pedestal attached to the timing belt and having an adsorption hole for adsorbing the sheet-like material, On the back side of the belt, provided in a region extending from a front end of the sheet-like material withdrawal path to a predetermined intermediate portion, and has an opening on a surface facing the timing belt. A suction chamber for applying a suction force to the suction hole of the suction pedestal; and a guide rail which is provided to protrude from both sides of the timing belt toward the draw-out path and supports the sheet-like material at a distance from the timing belt. are doing. Further, the transporting means is configured to receive the sheet-like material at a position where the suction state by the suction conveyor is released.

According to the third aspect of the invention, similarly to the first aspect of the invention, the sheet-like material fed by the feeding roller is directly transferred to the suction conveyor, so that the structure of the apparatus is simplified. In addition, only the operation timings of the feeding roller and the suction belt need to be considered when transferring the sheet material, so that the control becomes easy.

The suction conveyor adsorbs and pulls out the sheet-like material fed by the feeding roller onto the suction pedestal, and releases the suction state of the sheet-like material when the suction pedestal passes the end of the suction chamber. After the suction state by the suction conveyor is released in this way, the conveying means receives the sheet-like material and conveys it downstream, so that the sheet-like material can be smoothly transferred from the suction conveyor to the conveying means. it can.

Further, even if the suction force acting on the suction chamber leaks from both sides of the timing belt, the guide rail supports the sheet-like material away from the timing belt, so that the leaking suction force causes the sheet-like material. Can be prevented from being adsorbed.

In the invention of each of the above constructions, when a sheet-like material is further transferred from the delivery roller to the suction conveyor, the peripheral speed of the delivery roller is substantially equal to the peripheral speed of the suction conveyor. If peripheral speed control means for controlling the peripheral speed of the feed roller or the peripheral speed of the suction conveyor is provided (claim 4),
At the time of delivery of the sheet material, the sheet material is not pulled or compressed due to the peripheral speed difference between the feeding roller and the suction conveyor, so that extremely smooth delivery can be realized.

Further, the feeding roller, the suction conveyor and the conveying means are driven by a single drive source, and the peripheral speed control means is constituted by a pair of eccentric gears meshing with each other, and the driving is performed via the pair of eccentric gears. If the driving force of the power source is transmitted to the suction conveyor (claim 5), the control of the driving source is easy, and the peripheral speed of the suction conveyor can be automatically and stably controlled by the eccentric gear. it can.

The invention of claim 6 is characterized in that the suction holes of the feeding roller are shaped or arranged so that the suction area increases in the circumferential direction. For example, the suction hole of the feeding roller
It is characterized in that it is a long hole extending in the circumferential direction, or a plurality of holes are formed side by side in the circumferential direction.
8). ADVANTAGE OF THE INVENTION According to this invention, even if clearance gaps, such as a small hole and a spot, are scattered in a sheet-like material, the surface of this sheet-like material can be reliably adsorbed. In addition, since the suction area of the suction holes expands in the circumferential direction, the suction force from the suction holes gradually acts on the sheet-like material in the stocker with the rotation of the feeding roller, so that the sheet-like material is Is attracted to the peripheral surface of the feeding roller. For this reason, only the sheet-like material in the lowermost layer in the stocker can be reliably sucked and taken out.

According to a ninth aspect of the present invention, the stocker is formed so as to be surrounded on all sides by a support plate, and a lower portion of the support plate provided on a front end side where a feeding roller starts to take out a sheet-like material; A lower portion of the front end of the support plate provided on the left and right is formed with a notch, and an opening / closing guide for opening and closing the notch portion of the support plate provided on the front end side is provided.

According to the present invention, when the opening / closing guide is opened when the feed-out roller sucks and takes out the front end of the sheet-like material disposed in the lowermost layer in the stocker, the front end and the side of the sheet-like material can be opened. The front end side of the end is opened, so that there is no possibility that those portions of the sheet-like material are caught on the inner wall of the stocker, and it is possible to avoid taking out the sheet-like material.

Further, the invention according to claim 10 is characterized in that an alignment pressing guide is provided for pressing the rear end of the sheet-like material stacked on the stocker toward the front end to align at least the front end of the sheet-like material.

According to the present invention, since the aligning and pressing guide is provided, for example, when there is an individual difference in the molding dimension of the sheet-like material, when the sheet-like material is stored in the stocker, Even in the case where the front ends are irregular, the front ends of the stacked sheet materials can be aligned along the inner wall of the stocker by pressing the rear end of the sheet materials toward the front end by the alignment pressing guide. . Therefore, the feeding roller can reliably take out and take out the front end portion of the sheet-like material in the lowermost layer at a predetermined position.

The invention according to claim 11 is characterized in that immediately before the rear end of the lowermost sheet-like material is wound around the feeding roller,
A flip-up pusher that pushes up the rear end of the sheet-like material stacked above the sheet-like material is provided.

According to the present invention, since the flip-up pusher is provided, just before the rear end of the lowermost sheet-like material is wound around the feeding roller, the rear end of the sheet-like material stacked above the sheet-like material is removed. By pushing up the end with a pusher, even if there is a large frictional resistance between the stacked sheets, such as laver or handmade Japanese paper, the lowermost sheet can be reliably removed. It can be peeled and taken out from the sheet-like material above it.

Each of the timing belts 62 is provided with an adsorption pedestal 64 having an adsorption hole 63 at a predetermined position, and the laver 1 is adsorbed on the adsorption pedestal 64 and transported. In the present embodiment, the suction pedestals 64 are provided at two positions on the timing belt 62.
, And transports two sheets of seaweed 1 per rotation of the timing belt 62. Each timing belt 6
The mounting positions of the suction pedestals 64 mounted on 2 are adjusted so as to run in parallel while maintaining the same width direction position.

On the back side of the timing belt 62,
A suction chamber 65 is provided in a region extending from the front end of the laver 1 drawing path to a predetermined intermediate portion. This suction chamber 6
The inside of 5 is communicated with a suction pump (not shown), and the suction pump sucks the vacuum. The suction chamber 65 has an opening on the surface facing the back side of the timing belt 62. When the suction hole 63 formed in the suction pedestal 64 passes through the opening of the suction chamber 65, a suction force is applied to the suction hole 63. With this suction force, the laver 1 is adsorbed on the adsorption pedestal 64. Then, the suction force to the suction hole 63 is released when the suction pedestal 64 has passed the end of the suction chamber 65 (adsorption releasing means). There is a configuration to move to.

On both sides of the suction belt 62,
The guide rail 66 is formed so as to protrude above the suction belt 62 (toward the drawing path). The laver 1 adsorbed on the adsorption pedestal 64 is conveyed while sliding on the guide rail 66.

As shown in FIGS. 11 and 12, the pusher conveyor 70 is disposed at an intermediate portion of a plurality of timing belts 62 arranged in parallel with the suction conveyor 60. The pusher conveyor 70 has a plate-like pusher 71.
The positional relationship between the pusher 71 and the pusher conveyer 70 is adjusted such that the pusher 71 protrudes from the middle of the drawing path formed by the timing belt 62 onto the same path.

As described above, the seaweed 1 sucked by the suction pedestal 64 and pulled out, and then left on the drawing path, is pressed by the pusher 71 moving from behind and is conveyed downstream.

The above-described feeding roller 30, suction conveyor 60, and pusher conveyor 70 are driven by the driving mechanisms shown in FIGS.

As shown in FIGS. 13 and 14, a driving sprocket 91 a is mounted on a driving shaft 91 of a motor 90 as a single driving source, and the driving sprocket 91 a A driven sprocket 83a mounted on a crankshaft 83 that is a rotation drive medium
And via a first chain 92.

Further, the driving sprocket 91a is connected to the driven sprocket 72a mounted on the driving shaft 72 of the pusher conveyor 70 via a second chain 93 and a third chain 94. Here, the second chain 93 and the third chain 94 are connected to the intermediate transmission shaft 9.
5 are interlocked with the driven sprockets 95a and 95b mounted thereon. That is, the intermediate transmission shaft 95 is rotationally driven by the second chain 93, and the third chain 94 is rotationally driven by the rotational driving force.

The intermediate transmission shaft 95 is provided with a first gear 96a.

Of the first to fourth gears 96a to 96d,
Eccentric gears are employed for the first gear 96a and the second gear 96b. By appropriately setting the amount of eccentricity of the gears 96a and 96b, the rotation of the suction conveyor 60 with respect to the constant speed rotation of the motor 90 is achieved. The peripheral speed is varied at the following timing.

That is, when the seaweed 1 is delivered from the delivery roller 30 to the suction conveyor 60, the third and third seams are set so that the delivery timing of the seaweed 1 by the delivery roller 30 and the movement timing of the suction pedestal 64 of the suction conveyor 60 match. The timing of the suction conveyor 60 is controlled by the four gears 96c and 96d. On the other hand, during the delivery of the laver 1, the first and second laminations are set to be substantially equal to the peripheral speed of the feed roller 30 in order to prevent the laver 1 from being broken due to excessive tension. The peripheral speed of the suction conveyor 60 is controlled by the gears 96a and 96b.

Next, the operation of taking out one sheet of laver 1 from the stocker 10 by the sheet-like material supply device described above will be described.
This will be described with reference to FIGS. The laver 1 stacked and stored on the stocker 10 is aligned with a pressing guide 20.
The front end is aligned along the inner wall of the front support plate 11 by the reciprocating movement in the front-rear direction.

As shown in FIG. 15, the feeding roller 30 starts the operation of sucking the laver 1 from the front end position of the stocker 10. That is, by the rotation of the crank member 82,
The feeding roller 30 moves forward together with the frame body 80,
The feeding roller 30 is disposed at the front end position of the laver 1. In this position, the valve 33 shown in FIG.
The suction force from 4 acts on the suction hole 32 of the feeding roller 30. With this suction force, the front end of the laver 1 is attracted to the peripheral surface of the feeding roller 30.

When the feeding roller 30 is at the front end position of the stocker 10, the roller 85a of the pushing plate 85 attached to the inner surface of the frame 80 is rotated by the opening / closing guide 15 as shown in FIG. The lever 15b is pressed forward to rotate the opening / closing guide 15 forward, and the notch 14 formed at the lower portion of the front support plate 11 is opened. For this reason, the lower part of the front support plate 11 is opened together with the lower front ends of the left and right support plates 12, and the front end and both front sides of the laver 1 are set in a free state in which they do not come into contact with the inner wall of the stocker 10. 1 can be realized.

Further, since the suction area is enlarged in the circumferential direction because the suction holes 32 are elongated holes extending in the circumferential direction, the suction area of the seaweed 1 is widened and even the seaweed 1 having small holes can be reliably sucked. . Moreover, since the suction force from the suction holes 32 gradually acts on the laver 1 in the stocker 10 with the rotation of the feed roller 30, the laver 1 is brought into the peripheral surface of the feed roller 30. Is absorbed.

Next, the crank member 82 is rotated clockwise from the position shown in FIG. 15, and with this rotation, the feeding roller 30 is rotated backward from the suction position together with the frame body 80, and the adsorbed laver 1 is moved around its periphery. (Figure 1)
7).

Subsequently, as shown in FIG. 18, with the rotation of the crank member 82, the leading end of the laver 1 wound around the feed roller 30 is pulled out to the lower position of the feed roller 30. At this time, the valve 33 (see FIG. 9) is closed, and the suction force acting on the suction hole 32 of the feeding roller 30 is released.

At this timing, as shown in FIG.
