Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material feeder, and more particularly to a sheet feeder structure suitable for gripping a sheet material and laying it at a predetermined position.

[0002]

2. Description of the Related Art In various parts factories, manufactured parts taken out from a parts processing apparatus are housed in containers such as pallets, and the parts are transported and shipped for each container. Here, particularly when accommodating thin or strip-shaped components in a container, there is a problem that the components are bent and deformed when a large number of components are loaded in the container as they are. Further, particularly in the case of a component having a complicated shape, since the components are entangled with each other in the container, it is difficult to take out the component, and further there is a problem that the component is deformed at the time of taking out. Therefore, conventionally, a sheet material such as newsprint is laid inside the pallet, and the parts are arranged or dispersed on the pallet and accommodated. When the parts are accommodated on almost the entire surface of the sheet material, the next sheet material is again provided. Is laid on it, and the work of accommodating further parts is repeated alternately. In this way, since each of the components is spread in a state of being sandwiched between the sheet materials, it is possible to prevent the components from being deformed and prevent the components from being entangled with each other.

[0003]

However, in the above-mentioned conventional method for accommodating the parts, it is necessary to manually lay the sheet material with an operator by the side of the pallet.
Since it is necessary to carefully lay the sheet material on the parts at short time intervals, it is impossible to leave the machine next to the machine even for a while, and there is a problem that the manufacturing cost increases due to the labor cost and the like. Further, when the sheet material laying work is performed mechanically in order to eliminate the need for manpower, stress is applied to the parts housed below when the sheet material is laid, and the parts are deformed, while stress is applied to the parts below. If it is operated with a small driving force because it is not added, there is a problem that automation is extremely difficult because the sheet material cannot be laid horizontally.
Therefore, the present invention is to solve the above-mentioned problems, and to automatically perform the laying operation of the sheet material,
An object of the present invention is to obtain a device that can be laid securely without applying a large stress to the sheet material.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a plurality of sheet holding means arranged on a substantially flat surface and a sheet holding means are rotatably mounted in or near the arrangement surface of the sheet holding means, and are arranged on the arrangement surface. An extension member that extends along the extension member, a rotation driving unit that rotates the extension member downward from the installation surface, and a transfer unit that moves the installation surface are provided.

Here, it is preferable that the extension member is a member having flexibility at least in its extension direction.

Further, it is preferable that the extension members are attached to both ends of the mounting surface and extend toward the other end.

Further, it is preferable that a gas spraying means is provided on the above-mentioned disposition surface so as to spray gas when the sheet material is separated from the holding means.

And, it is arranged substantially parallel to the above-mentioned arrangement surface,
A supporting surface capable of supporting the sheet material in a stacked state, a supporting surface moving means for moving the supporting surface in the sheet material stacking direction, and at least between the sheet material holding time of the sheet holding means and the sheet material transferring time. It is desirable to provide a control means for moving the support surface backward with respect to the sheet holding means by the support surface moving means.

Alternatively, it is arranged substantially parallel to the above-mentioned arrangement surface,
A supporting surface capable of supporting the sheet material, and a sheet introducing means for guiding the sheet material from the roll around which the sheet material is wound to the supporting surface,
It is preferable to provide a sheet cutting means for cutting the introduced portion of the introduced sheet material.

[0010]

According to the first aspect, the sheet material can be held by the plurality of sheet holding means and the sheet material can be transferred by the transfer means. In this case, when releasing the sheet material on the predetermined laying surface, if the extension member mounted in or near the arranging surface is rotated downward, the held sheet material is pressed against the laying surface. Therefore, the sheet material can be quickly separated from the sheet holding means and can be surely laid on the laying surface.

According to the second aspect, by using the flexible member as the extension member, the laying operation of the held sheet material can be performed flexibly, and the flexibility of the extension member provides a flat surface. It can be laid on any laying surface other than. In this case, the laying pressure suitable for the sheet material or the laying work can be obtained by adjusting the degree of flexibility. Further, by using the elastic strip as the extension member, it is possible to surely lay even if the laying surface has irregularities. In particular, by extending and arranging a plurality of strips along the arrangement surface, it is possible to reliably lay the sheet material while suppressing the pressing force applied to the laying surface.

According to the third aspect, the mounting positions of the extension members are at both ends of the disposition surface, and the extension members are extended from one end to the other end, whereby both ends of the sheet material are lowered. Since it can be pressed against, stable laying operation becomes possible.

According to the fourth aspect, by providing the gas spraying means on the mounting surface, the sheet material can be reliably released from the sheet holding means. In this case, by arranging the plurality of gas spraying means on the mounting surface in an appropriately dispersed manner, the sheet material can be laid more reliably.

According to the fifth aspect, the supporting surface moving means controlled by the control means moves the supporting surface backward with respect to the sheet holding means from the time when the sheet holding means holds the sheet material, and therefore the sheet to be transferred. The material can be reliably separated from the lower support surface or other sheet material laminated below, and the lower sheet material is rolled up due to deformation of the sheet material, abnormal mounting state, or static electricity. Can be prevented. In particular, the sheet material can be stably transferred even to a thin and flexible sheet material.

According to the sixth aspect, the sheet material is introduced from the roll onto the supporting surface by the sheet introducing means, and the introducing portion of the sheet material is cut by the sheet cutting means. Therefore, the sheet material is laminated thickly on the supporting surface. Since it is not necessary to feed the sheet material onto the support surface frequently, it is possible to feed a large number of sheet materials at a time from a compact device.

[0016]

The fitting portion 35a is introduced into the U-shaped groove 36a and rotatably fitted therein.

As shown in FIGS. 2 (a) and 2 (b), the carrier plate 11 is bent downward on both sides of the support plate 10, and both ends of the support plate 10 having the mounting slots 11a are formed. It is configured to be located below. The suction member 12 attached to the attachment long hole 11a has a suction plate 1 at the lower end.
Equipped with 2a. A shaft member 12b, which is attached so as to be able to move up and down and is urged downward by a coil spring (not shown), is inserted into the suction member 12.
A suction plate 12a is attached to the tip of 2b. Therefore, each suction plate 12a can come into contact with a sheet or the like with a predetermined degree of freedom in the height direction. Adsorption member 1
An air suction pipe 42 is connected to the inside of 2 to suck air from the suction plate 12a under the control of an opening / closing valve (not shown).

The spray member 13 attached to the center of the carrier plate 11 has a spray nozzle 13a at the lower end.
The blowing member 13 is connected to the air introducing pipe 43 and blows compressed air from the blowing nozzle 13a under the control of an opening / closing valve (not shown). Note that, in FIGS. 1 and 2, pipes connected to the suction member 12, the spraying member 13, and the air cylinder 32 are omitted except for a part.

The sheet feeding head 1 described above is shown in FIG.
As shown in FIG. 1, the newsprint 6 laminated on the sheet support plate 2
It is located above 0. Here, the internal structure of the sheet supply head 1 is omitted in FIG. The support plate 10 of the sheet supply head 1 is fixed to a moving plate 51, and the moving plate 51 is supported by three piston rods 52 so as to be able to move up and down. The piston rod 52 is driven by an air cylinder 53, and the air cylinder 53 is fixed on the guided member 54. The guided member 54 is movably mounted along a linear guide 55 extending in the horizontal direction. A weight 57 is attached to the moving plate 51 via a connecting plate 56, and the sheet feeding heads 1 and the weights 57 attached on both sides are substantially balanced with each other with three piston rods 52 as fulcrums. ing.

The seat support plate 2 is connected to the drive screw shaft 3 and is supported on the base 5 by a pair of support rods 4 and 4. Further, around the drive screw shaft 3 and the support rod 4, six guide shafts 37 are fixed on the base 5 at six places. The guide shafts 37 pass through the sheet support plates 2 and define the horizontal position of the laminated newspaper 60 from the periphery. The drive screw shaft 3 is screwed into a nut member 38 rotatably provided inside the base 5, and
It is fixed to a reinforcing plate 39 connected to the support rod 4. The nut member 38 is connected to a drive motor 59 via a drive belt 58, and is rotated by the drive motor 59.

A pallet transfer device (not shown) is arranged beside the sheet support plate 2 to support the pallets 6 in a stacked state. Above the pallet 6, a front end portion of a transfer conveyor 7 rotatably attached on a horizontal plane is arranged. A conveyor unit 8 is attached to the transport conveyor 7 so as to be movable in the transport direction, and the position of the component 70 falling from the transport belt 9 into the pallet 6 can be freely changed. That is, within the range of the opening surface of the pallet 6, the drop position of the component 70 is moved by the rotation of the transport conveyor 7 and the withdrawal of the conveyor unit 8.
The pallets 6 are designed so that the parts 70 fall in a dispersed state inside the pallet 6.

Next, the operation of this embodiment having the above structure will be described. When the components 70 are sequentially supplied from the conveyor 7 to the pallet 6 and the components 70 are accommodated over substantially the entire opening surface of the pallet 6, the components 70 are stored in the pallet 6 so that the components 70 do not become entangled due to stacking. Newspaper 60 needs to be laid. When laying the newspaper 60, each part is operated as follows. Here, the following operations are all performed by controlling a drive switch, an air opening / closing valve, etc. of each part by a programmable controller (not shown). Before starting the laying operation, the transport conveyor 7 stops the component supply, and if necessary, the conveyor unit 8 is retracted and retracted from the opening surface of the pallet 6. FIG. 4A shows the shape of the sheet supply head 1 as viewed from the sheet supply direction at this time.

First, the piston rod 52 is lowered by the air cylinder 53 shown in FIG. 3 to lower the entire sheet feeding head 1. When the suction plate 12a of the suction member 12 comes into contact with the uppermost newspaper 60 by the lowering of the sheet supply head 1, air is sucked from the suction plate 12a, as shown in FIG.
The newspaper 60 is adsorbed as shown in FIG. At this time, steel wire 2
Since 1, 22, 23, 24, 25, and 26 press the newspaper 60 adsorbed on the suction disk 12a over almost the entire length, the newspaper 60 placed on the sheet support plate 2 may be slightly wrinkled or folded. Even if it is wavy, it can be corrected and adsorbed in a substantially horizontal state. In this state, the sheet support plate 2 slowly descends due to the rotation of the drive motor 59, and the sucked uppermost newspaper 60,
The many newspapers 60 laminated underneath are slowly separated. When the newspaper 60 attracted to the sheet feeding head 1 is sufficiently separated from the other newspapers, the air cylinder 53 raises the piston rod 52 to raise the sheet feeding head 1 to the uppermost position.

The descending operation of the sheet supporting plate 2 as described above surely separates the newspaper 60 attracted to the sheet feeding head 1 and the stacked newspapers on the sheet supporting plate 2,
Ensure the transport of newspapers. In particular, when a flexible and thin sheet is used, the holding between the suction member 12 and the sheet is partially incomplete due to wind, wrinkles of the sheet, static electricity accumulated on the sheet, or the like, or the sheet comes off from the sheet feeding head 1. There is a risk that the lower sheet will be rolled up. However, in this embodiment, the uppermost newspaper can be reliably held by slowly retracting the sheet support plate 2 as described above, and the held newspaper can be reliably separated from the lower newspaper and then transferred. Since it starts, it is possible to prevent the lower newspaper from being caught.

Next, the guided member 54 shown in FIG. 3 moves to the pallet side along the linear guide 55, and moves the sheet feeding head 1 to a position above the opening surface of the pallet 6. Here, air suction of the suction member 12 is stopped and air is sprayed from the spray nozzle 13a of the spray member 13 to separate the sucked newspaper 60 from the sheet supply head 1. At the same time, the air cylinder 32 pulls in the piston rod 33 and rotates the lever member 36 to the front as shown in FIG. 4C, so that the steel wires 21, 22, 23, 24, which are attached to the attachment member 15, 25, 26
Rotate downward and push the newspaper 60 into the pallet 6.

When the newspaper 60 has been laid inside the pallet 6, the air cylinder 32 again pushes out the piston rod 33, and the steel wires 21, 22, 23, 24, 25 and 26 respectively rotate upward to return to the original state. Return to position. Then, the sheet supply head 1 returns to the position above the sheet support plate 2 again along the linear guide 55. The above operation is repeated every time the components 70 are dispersed and housed in the pallet 6,
A certain number of layers (for example, 5 layers) according to the capacity of the pallet 6
When the parts 70 (which are laid on the newspaper 60 for each layer) are accommodated in the pallet 6, the pallet 6 is transferred by the pallet transfer device and replaced with an empty pallet.

The sheet support plate 2 may be constructed so that its reference height is adjusted according to the number of laminated newspapers 60, the laminated thickness or the laminated weight. The sheet supporting plate 2 slowly descends after the sheet feeding head 1 has adsorbed the uppermost newspaper 60, but this descending operation is continued for a predetermined set distance based on the reference height. . When the sheet feeding head 1 moves above the pallet 6 while sucking the newspaper 60, the sheet support plate 2 returns to the reference height corresponding to the amount of newspaper at that time.

The elasticity of the steel wire allows the sheet material to be laid substantially horizontally in the pallet without applying a large stress to the sheet material such as newsprint and without deforming the parts accommodated therebelow. To enable. Especially when the laying surface has irregularities, the flexible member or the elastic member is used as the extension member to lay the sheet material while the extension member is deformed according to the laying surface. No large pressing force is applied. Also,
By using multiple strips of steel wire etc. as extension members,
It is possible to perform the laying operation according to the unevenness of the laying surface while reducing the pressing force on the laying surface. This extension member is particularly effective when laying a sheet material in a recess such as a pallet. Here, when the parts are housed in layers in the pallet, the sheet laying height in the pallet gradually rises, but since the steel wire bends in the pallet, raising the laying position almost affects the laying state. Absent. However, when the installation position changes greatly, it is preferable to control the operation of the air cylinder 32 to change the rotation angle of the rotation shaft 15 stepwise.

The sheet holding means is not limited to the above-mentioned attraction member, but may be a surface fastener, an electrostatic attraction tool, a magnet or an electromagnet (when the sheet material is a magnetic material), or the like. Further, the attachment position of the extension member is not limited to the end portion, and may be provided at any position within the vicinity of the arrangement surface (the surface on which the sheet is held), and the number of extension members to be provided is also arbitrary. is there. Further, it is preferable that the sheet holding means such as the suction member and the gas spraying means such as the spraying member are arranged substantially evenly distributed on the disposition surface, but the disposition and the number thereof are the material, thickness and weight of the sheet material. It can be appropriately set according to the above.

FIG. 5 shows the construction of another embodiment of the sheet material feeding apparatus according to the present invention. In FIG. 5, the same parts as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this apparatus, a sheet roll 61 wound with a sheet material is rotatably mounted on a support shaft 62 attached to the apparatus main body. Sheet material 6 wound on a sheet roll 61
3 is a pressing roller 8 formed at the right end of the sheet base 80.
1, 82 and the drive rollers 83, 84 facing them are pulled out in a state of being sandwiched. Drive roller 83,
84 is driven to rotate by a drive motor 85. A sheet cutting device 86 is attached to the seat base 80, and includes an air cylinder 86a and an air cylinder 86.
holder 86c connected to piston rod 86b of a
And a pressing roller 86 attached to the lower end of the holder 86c so as to be able to move up and down while being urged downward by a spring or the like.
d and the holder 86 in parallel with the pressing roller 86d.
It is composed of a cutter 86e attached to c and a cutter hole 86f into which the cutter 86e is inserted. On the left side of the sheet cutting device 86, the pressing roller 87 and the conveyor 8
8 is installed, and each drive roller of the conveyor 88 is driven by a drive motor 89.

A drive screw shaft 90 and support rods 91, 91 are attached to the bottom surface of the seat base 80, and the drive screw shaft 90 and the support shaft 91 are fixed to a reinforcing plate 92 at their lower ends. The drive screw shaft 90 is screwed into a nut member 93 rotatably attached to the frame, and the drive belt 9
It is adapted to be rotatably driven by a drive motor 95 via 4. Above the sheet table 80, the above-described sheet supply head 1 and the sheet supply head 1 for driving the sheet supply head 1 shown in FIG.
A drive system similar to the above is provided.

The drive motors 85 and 89, the drive rollers 83 and 84, and the conveyer conveyor 88 constitute a sheet conveyer (BC), which is automatically operated by a controller (not shown). The operation of this embodiment is shown in FIG.
When the sheet conveying device (BC) is turned on, the drive motor 8
5, 89 is activated and the sheet material 63 is fed from the sheet roll 61.
Pull out. The amount of sheet material to be drawn is determined by the drive roller 83
The rotation amount of 84 can also be set, but in this device, when the distance is measured to the left with the cutting position of the cutter 86e as a reference, the predetermined reference position SP and the reference position SP
An optical sensor is arranged at a position obtained by subtracting the conveyance allowance d from the above to detect the leading end position PE of the sheet material 63. When the front end position PE of the sheet material 63 becomes SP-d, the conveyer (BC) is turned off and the drive motor 8
Stop 5,89. Here, the distance d is a distance required for the rear end of the sheet material to move from immediately below the cutter 86e and escape from the position immediately below the pressing roller.

Next, when the sheet cutting device (CM) is activated, the air cylinder 86a lowers the piston rod 86b, and the pressing roller 86d first comes into contact with the sheet material 63.
And then the cutter 86e cuts the sheet material 63. When the sheet material 63 is cut, the sheet conveying device (BC) is activated again, and the drive motor 89 causes the conveying conveyor 8 to move.
8 is driven to convey the sheet material 63 to the left. At this time,
At the same time, the drive motor 85 operates to move the sheet material to be cut next time to below the pressing roller 87. When the front end position PE of the cut sheet material 63 reaches the reference position SP, the rear end of the sheet material 63 comes to a position slightly left from the position directly below the pressing roller 87, and in this state, the sheet conveying device (BC ) Stops. At this time, the cut sheet material 6
3 is in a state of being installed at a position facing the sheet feeding head 1, and thereafter, the sheet material 6 is subjected to the same steps as in the above embodiment.
3 will be supplied and laid. When the supply of sheet material is completed,
The sheet conveying device (BC) is activated again, and the above operation is repeated. In the above operation, the sheet roll 61
As the winding diameter of the sheet material is reduced, the drive motor 95 raises the sheet base 80 to adjust the withdrawal height of the sheet material 63. The seat base 80 descends when the 63 is suction-held.

In the above apparatus, since the sheet material 63 is introduced from the sheet roll 61 onto the sheet base 80 and supplied, it is not necessary to thickly stack the sheet material, or the sheet material is frequently supported by the sheet. There is an advantage that a large number of sheet materials can be supplied from an apparatus having a small volume, without having to be placed on a plate. In this case, ordinary paper, resin sheet, or the like is used as the sheet material, but since these are roll-shaped, the curl often remains even after being pulled out. In the present embodiment, even in such a case, the sheet material on the sheet base can be adsorbed while being pressed by the steel wire, so that it is possible to avoid the retention failure due to the curl.

[0037]

As described above, according to the present invention, when the sheet material is laid, the extension member attached to the inside of the arrangement surface or in the vicinity thereof is rotated downward, so that the held sheet material can be removed. Since the sheet material can be pressed at a predetermined point with a predetermined pressing force, the sheet material can be reliably laid regardless of the material of the sheet material and the state of the laying surface.
