[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention is a stacker device in which a sheet cut into a standard shape is superposed in alignment with a sheet fed later under a sheet fed earlier, and the sheet is splashed. The present invention relates to a weight mechanism for holding the weight so that it does not rise.

[0002]

2. Description of the Related Art A stacker as shown in FIG. 4 is used for stacking a sheet cut into a fixed shape such as an address label of a postal matter so that the sheet sent later is aligned under the sheet sent earlier. The device is in use. This stacker device 1
A roller 20 sends a sheet 18 sent by a printing / cutting device (not shown) toward a stacking position 19, and a back wall 21 for stopping the sent sheet 18 by abutting it. A column 22 and a guide 23 for positioning the sheet 18 at the stacking position 19 and a groove 22a provided in the column 22 are movably attached to apply a load to the upper surface of the sheet 18 and prevent the sheet 18 from jumping up. The weight member 24 of FIG. In the stacker device configured as described above, when the sheet 18 is fed from the printing / cutting device , the feed roller 20 feeds the sheet 18 toward the stacking position 19. The seat 18 pushes up the weight member 24 and stops when coming into contact with the back wall 21, and the weight member 24 applies a load from above. And when the next sheet is sent,
The next sheet pushes up the sheet 18 at the stacking position 19 and the weight member 24, is inserted under the sheet 18 at the stacking position 19 and is stacked. At this time, stacking position 1
Since the sheet 18 of 9 has a load applied by the weight member 24, the sheet 18 is not flipped up by the sheet inserted below, and the two sheets can be aligned and stacked. This is repeated and many sheets are aligned and stacked.

By the way, the stacker device having the above-mentioned structure has a problem that too many sheets cannot be stacked. The weight member 24 is the seat 1
The load applied to 8 is always constant. Therefore, when the amount of the stacked sheets 18 increases, the load applied to the lowermost sheet increases in proportion thereto, and it becomes difficult to push up the stacked sheets 18 when inserting the next sheet. Therefore, it was not possible to stack too many sheets.

[0004]

Therefore, an object of the present invention is to increase the number of sheets that can be stacked in a stacker device.

[0005]

In order to achieve the above-mentioned object, the present invention continuously feeds sheets cut in a fixed form to a stacking position, and then sends the sheets below the sheet previously sent. In a stacker device that aligns and stacks the stacked sheets, the stacker is rotatably supported on the left and right sides of the stacking position in the feed direction, and is rotatably supported by a shaft extending in the feed direction. It is characterized in that it is provided with a weight member that is pivotally displaced to load a load that is gradually reduced on the sheets at the stacking position.

[0006]

[Function] The weight member is rotationally displaced according to the amount of sheets brought to the stacking position, and as the amount of sheets increases,
The load applied to the seat by the weight member is reduced. Therefore, the sum of the weight of the stacked sheets and the load applied to the sheets by the weight member does not increase in proportion to the amount of sheets. Therefore, since more sheets can be pushed up, more sheets can be stacked.

[0007]

Embodiments of the present invention will be described below. As shown in FIG. 1, the stacker device 1 of the present invention stacks sheets stacked by a printing / cutting device (not shown) at a stacking position 2 for aligning and stacking sheets cut in a fixed shape. A pair of endless belts 3 for feeding toward the position 2, a back wall 4 for stopping and abutting the sheets fed to the stacking position 2, and a sheet feeding direction when the sheets are fed by the belt 3. And a pair of weight members 6 rotatably supported by shafts extending in the feeding direction on the left and right sides of the stacking position 2 in the sheet feeding direction.

As shown in FIG. 2b, the endless belt 3 is engaged with the driving roller 7 and rotates in the direction of the arrow. A pressing roller 8 is provided above the endless belt 3, and the pressing roller 8 is elastically biased downward by a spring (not shown) and is pressure-bonded to the endless belt 3. Also, as shown in FIG.
The guide mounting brackets 10 are mounted on the casings 9 on both the left and right sides of the stacking position 2, and the guide mounting brackets 1
2 is provided with an elongated hole 10a, and as shown in FIG. 2b, the sheet guide 5 and the weight guide 13 are connected to the spacer 1 by a knob screw 11 and a nut 12 which penetrate the elongated hole 10a.
It is fixed to the guide mounting member 10 via 4.
Then, as shown in FIG. 2A, a weight member 6 made of metal is rotatably supported by the weight guide 13 by a shaft 15 extending in the feeding direction. For the sheet guide 5 and the weight guide 13, the knob screw 11 is loosened, and the long hole 1
By moving along 0a, it is possible to change to any position. Therefore, it is possible to deal with sheets of various widths.

In the stacker device having the above structure, the sheet 1 cut into a fixed shape by the printing / cutting device
When 6 is sent, the sheet 16 is sandwiched between the pressing roller 8 and the endless belt 3, and is sent toward the back wall 4. The sheet 16 is regulated in the feeding direction by the sheet guide 5, pushes up the weight member 6, and abuts on the back wall 4,
Stop at stacking position 2. Both side edges of the stopped sheet 16 are pressed by the weight member 6. Figure 3a shows that situation. And the sheet 16 sent next
Pushes up the sheet 16 and the weight member 6 at the stacking position 2 and is stacked below them. At this time, since the sheets 16 at the stacking position 2 are pressed by the weight member 6, the two sheets 16 can be aligned and stacked without being flipped up when the sheets 16 are inserted below.

When the stacking height of the sheets 16 is increased by repeating this, the weight of the sheets 16 pushed up gradually increases. On the other hand, the weight member 6 is pushed up by the seat 16 and pivotally displaced around the shaft 15,
As shown in FIG. 2B, the sheet 16 comes into contact with the sheet 16 at an angle, so that the sheet 16 brought to the stacking position 2
As the amount of the weight increases, the load applied to the seat 16 by the weight member 6 gradually decreases accordingly. Therefore,
Even if the stacking height of the sheets 16 increases, the sum of the weight of the sheets and the load applied to the sheet 16 by the weight member 6 does not increase in proportion thereto. Therefore, more sheets 16 can be pushed up and more sheets 16 can be stacked as compared with the conventional device. Then, when the stacking height of the sheets 16 becomes higher than that of the weight member 6, the weight member 6 pushes the sheets 16 from the side, as shown in FIG.
6 will come to work. Also, at this time,
Since the weight of the stacked sheets 16 acts as a substitute for the weight member 6, the sheets 16 inserted below
The stacked sheets 16 are not splashed up, and the sheets 16 can be aligned and stacked.

[0011]

As described above, when the weight mechanism in the stacker device of the present invention is adopted, the amount of stackable sheets can be increased as compared with the conventional stacker device. Therefore, the intended purpose can be achieved.
