DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-sheet block for tissue paper, wet tissue or the like.
The present invention relates to a device that reloads onto a second conveyor belt that runs in a direction perpendicular to the conveyor belt.

[0002]

The above-mentioned multi-sheet block is housed in a container and is continuously taken out from a pick-up port provided on a top plate. Accordingly, the sheets of these multiple sheet blocks are multiplexed so that they can be continuously taken out by a known method such as folding back and assembling with the other hand, and various sheet multiplexing apparatuses for that purpose are provided.

[0003] In these sheet multiplexing apparatuses, several multiplex sheet blocks can be mass-produced by arranging them one at a time in the axial direction of the holding roll. The blocks are arranged below the holding rolls, so that the blocks are stacked in parallel on the stacking conveyor belt (first conveyor belt), and further provided with a second conveyor belt running at a right angle at the unloading end of the first conveyor belt. At the unloading end of the first conveyor belt, the frontmost row of multiple sheet blocks is sequentially transferred onto the second conveyor belt, so that the first conveyor belt is placed in a row in the direction orthogonal to the belt operation direction and in the operation direction. The rows of multiple sheet blocks arranged in parallel are rearranged in the belt running direction on the second conveyor belt in a tandem state and used for a packing process or the like. It has been.

Thus, it is necessary to transfer each of the multiple sheet blocks from the discharge end of the first conveyor belt to the carry-in end of the second belt. A method of transferring the image onto the upper surface of the conveyor belt is employed.

In one example, the multiple sheet blocks received on the upper surface of the first conveyor belt are separated by a scraper into a second sheet block.
This is a method of scraping the upper surface of the conveyor belt.

However, in these methods, the multiple sheet blocks rub against the upper surfaces of the first and second conveyor belts.
There is always the problem of seat damage and load slippage.

In particular, when the multi-sheet block is a wet tissue, each sheet is impregnated with a chemical solution, so that it becomes more difficult to slip, and the above problem is exacerbated.

[0008]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and eliminates the causes of the above-mentioned sheet damage, unloading, etc., and can appropriately transfer the multiple sheet blocks from the first conveyor belt to the second conveyor belt. Thus, there is provided a multi-sheet block transfer device.

In this transfer device, the first transport belt is formed by a plurality of narrow belts running in parallel at intervals. And it is inserted into the space of the narrow belt and the first
A fork-type lifter that scoops up multiple sheet blocks from the upper surface of the conveyor belt is provided.

On the other hand, a fork type stopper is disposed on the outer side of the second conveyor belt in the direction orthogonal to the running direction, in other words, on the side opposite to the discharge end side of the first conveyor belt.

The fork-type lifter scoops up the multiple sheet blocks received on the upper surface of the first conveyor belt, and then moves the upper part of the second conveyor belt in a direction orthogonal to the belt traveling direction. It crosses through the shape stopper and the mutual fork interval.

At the time of the crossover, the fork-type stopper pushes the multiple sheet blocks received on the upper surface of the fork-type lifter to the upper surface of the second transport belt.

As a result, the multiple sheet blocks in each row in the horizontal row on the first transport belt are rearranged in the vertical row on the second transport belt. The first transport belt, the fork-type lifter, and the fork-type stopper, which have a structure in which the narrow belt runs in parallel, cooperate as described above so that the multiple sheet blocks are not rubbed with the upper surface of each belt. The transfer can be appropriately performed from the transport belt to the second transport belt.

When a multi-sheet block is extruded from a fork-type lifter, rubbing occurs. This distance is extremely limited as compared with the conventional distance of sliding from the upper surface of the first conveyor belt to the upper surface of the second conveyor belt. This minimizes the area of contact with multiple seat blocks, and the fork-type lifter can be made of a slippery material regardless of the belt. Can be resolved.

The fork-type stopper is provided so as to be movable in a direction away from and close to the side edge of the second conveyor belt. The belt is extruded onto the upper surface of the conveyor belt and is separated after the extrusion to prevent interference between the fork type stopper and the multiple sheet block.

Each of the forks of the fork-type stopper for pushing out the stacked sheet block has a ruler portion which protrudes from the side edge of the second conveyor belt to the upper surface of the belt and regulates the side surface of the stacked sheet block. Set the mounting position of the multiple seat block on the belt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a first conveyor belt 1 and a second conveyor belt 2 are arranged so as to run in directions perpendicular to each other. In other words, the first transport belt 1
Is provided with a second conveyor belt 2 running at right angles to the belt 1.

As shown in FIG. 2, a known sheet multiplexing device 3 is provided above the carry-in end of the second conveyor belt 2, and this sheet multiplexing device 3 produces a plurality of multiple sheet blocks 4 at a time. Each of the multiple sheet blocks 4 is discharged from the lowermost holding roll 11 forming the multiplexing device 3 in a line in the axial direction of the roll 11.

A row of the multiple sheet blocks 4 discharged from the holding roll 11 is
That is, a constant number of multiple sheet blocks are formed on the upper surface of the first fork type lifter 5, and after reaching the constant number of sheets, the first fork type lifter 5 is lowered. Is transferred to the upper surface of the carry-in end of the first conveyor belt 1.

The first conveyor belt 1 is formed by a plurality of narrow belts 6 running in parallel at intervals. That is, as shown in FIG. 1, a plurality of sprockets 9 and 10 are provided at equal intervals on shafts 7 and 8 around which the carry-in end and the carry-out end of the first conveyor belt 1 are wound. The width belt 6 is suspended and the shafts 7 and 8 are driven to rotate to operate synchronously.

Therefore, the lifter 5 is forked.
When each fork intervenes between the narrow belts 6 when descending, the multiple sheet blocks 4 are placed on the upper surface of the first transport belt 1.
Reprint.

After the first fork type lifter 5 transfers the multiple sheet blocks 4 to the upper surface of the first transport belt 1,
It rises again to receive the next multiple sheet block.

Although not shown, an auxiliary lifter is provided so that the operation of the sheet multiplexing device 3 is not stopped while the first fork type lifter 5 is lowered, and the holding roll 11 is placed on the auxiliary lifter. The first fork-type lifter 5 is raised to transfer the temporarily received sheet block from the auxiliary lifter to the upper surface of the first fork-type lifter 5. You can do so.

Alternatively, without the first fork-type lifter 5 and the auxiliary lifter, a manually assembled sheet of the phase unwound from the holding roll 6 can be directly stacked and grown on the upper surface of the carry-in end of the first conveyor belt 1. .

Thus, on the upper surface of the first conveyor belt 1, a plurality of multiple sheet blocks 4 discharged from the folding rolls 11 are loaded in a row in a row in a direction orthogonal to the running direction of the belt 1. The rows of the multiple sheet blocks 4 are accumulated in the running direction of the first conveyor belt 1 in a parallel state.

The first conveyor belt 1 is intermittently driven, receives the reloading of the multiple sheet blocks 4 from the first fork-type lifter 5 at the time of stop, and at the same stop, the frontmost multiple sheet block on the first conveyor belt 1. 4 is picked up by a second fork type lifter 12 described below, and is transferred onto the upper surface of the second conveyor belt 2.

The second fork type lifter 12 is shown in FIG.
As shown in FIG. 3, the fork 13 includes a plurality of forks 13 arranged in parallel to each other, and each of the forks 13 is a scooping unit 1 extending in parallel with the first conveyor belt 1 toward the loading end of the first conveyor belt 1.
The scoop-up section 14 has a side end restricting toward the belt 1 carrying-in end as a free end, and has a side-face regulating section 15 rising at right angles from the base of each fork 13 on the carrying-out end side of the belt 1.

The forks 13 are connected to each other by a connecting portion 16 at the upper end of the regulating portion 15, and the fork 13 of the second fork-type lifter 12 has an L shape as a whole.

As described above, the second fork type lifter 12 is configured such that when each of the forks 13 stops the first transport belt 1,
At the discharge end of the belt 1, the frontmost row of multiple sheet blocks 4 inserted into the plurality of intervals 17 between the narrow belts 6 and received on the belt 1 is scooped up by the row above the belt 1, and scooped up. Thereafter, the first conveyor belt 1 is laterally moved from the upper end of the discharge end on an extension of the operation direction of the belt 1.

The lateral movement causes the upper side of the second conveyor belt 2 to move in a direction orthogonal to the running direction of the belt 2 so as to traverse the belt 2 and cooperate with a fork-type stopper 18 described later at the time of traversing. Working, 2nd fork type lifter 1
The rows of the multiple sheet blocks 4 received by the second conveyor belt 2 are transferred onto the upper surface of the second conveyor belt 2.

After passing through the fork-shaped stopper 18, the second fork-type lifter 12 advances again to the discharge end of the first conveyor belt 1 and is inserted between the narrow belts 6 to scoop up the next multiple sheet block 4.

As an example of a means for causing the second fork-type lifter 12 to cause the above-described movement, a frame-shaped movable frame 19 is provided with a screw shaft 21 which is rotated by a motor 20, as shown in FIGS. The second fork-type lifter 12 is suspended from the screw shaft 21 with the connecting portion 16, and the suspended portion is screwed to the screw shaft 21. The shape lifter 12 moves forward and backward in the running direction of the first conveyor belt 1.

Further, the frame 19 provided with the screw shaft 21 and the motor 20 is suspended by an air or hydraulic cylinder 22 so as to be movable up and down. The required movement of the lifter 12 is obtained.

The fork-shaped stopper 18 is disposed on an extension in the running direction of the first conveyor belt 1. More specifically, the second conveyor belt 2 is adjacent to the discharge end of the first conveyor belt 1 on one side in a direction perpendicular to the running direction, and the fork-shaped stopper 18 is provided on the side opposite to the adjacent side. Distribute.

The fork-type stopper 18 rises vertically along the side edge of the second conveyor belt 2 and upwardly of the belt.
It has a fork portion 23 facing the discharge end of the conveyor belt 1, and the fork portion 23 forms a pressing portion of the multiple sheet block 4.

As shown in FIGS. 6A, 6B, and 7, the fork-type stopper 18 can intersect the second fork-type lifter 12 through respective fork intervals. When the fork-type lifter 12 traverses over the second conveyor belt 2 so as to cross the stationary fork-type stopper 18, the fork-type lifter 12 prevents lateral movement of the multiple sheet block 4 as a reaction, and
The fork-shaped lifter 12 extrudes the upper surface of the second conveyor belt 2. The second conveyor belt 2 operates intermittently and receives the transfer of the multiple sheet blocks 4 when stopped.

Each fork 13 of the second fork type lifter 12 and each fork 23 of the fork type stopper 18
Is provided with a pitch shifted so that the space between one fork and the other fork are opposed to each other, and arranged so that both forks can pass while crossing each other through the space between the forks.

The second fork type lifter 12 is moved along a locus indicated by an arrow in FIG. 7 as an example. That is, the lifter 12 moves the first transport belt 1
And is interposed between the narrow belts 6 so as to intervene between the sprockets 10 around which the carry-out ends are wound.

That is, fork 1 of fork type lifter 12
3 intervenes below the narrow belt 6 through the sprockets 10, and thereafter, as shown by the locus b, raises the multiple sheet blocks 4 received on the upper surface of the first transport belt 1 to form a belt by row. Scoop up.

Next, as shown by a locus c, the first conveyor belt 1 is moved from the upper end of the discharge end of the first conveyor belt 1 in the extending direction of the first conveyor belt 1 to move in the second direction.
The upper part of the conveyor belt 2 is traversed in a direction orthogonal to the belt operation direction. During this crossing, the fork pusher 18
And the block extrusion is performed.

It is desirable that the second fork-type lifter 12 be moved parallel to the upper surface of the second conveyor belt 2 after descending to a position as close as possible to the upper surface of the second conveyor belt 2 as shown by a locus c. As a result, it is possible to carry out block transfer while minimizing the drop between the second fork type lifter 12 and the multiple sheet block 4 received by the lifter 12 and the upper surface of the second transport belt 2 as much as possible.

The fork type stopper 18 is connected to the second
Whether it is fixed at a fixed position with respect to the side edge of the conveyor belt 2 or
Alternatively, it is provided so as to be movable in a direction away from and close to the side edge of the second transport belt 2.

This movable fork type stopper 18 is
At a position close to the side edge of the conveyor belt 2, the conveyor belt 2 stops and intersects with the second fork type lifter 12 to perform the extrusion of the multiple sheet block 4.

Immediately after the extrusion of the block 4, the second
It retreats to a position away from the side edge of the conveyor belt 2 and separates the fork 23 from the side surface of the block 4 to prevent the second conveyor belt 2 from interfering with the block during operation.

As means for moving the fork pusher 18 in the lateral direction, for example, the base (lower end) of a fork 23 is connected by a connecting portion 24, and an air or hydraulic cylinder 25 is attached to the connecting portion 24.
At 5, the fork pusher 18 is moved back and forth between the approach position and the separation position at a predetermined timing.

Further, as a specific example of the fork-type stopper 18, a ruler 26 projecting from the side edge of the second conveyor belt 2 to the upper surface of the fork 23 forming the push-out portion of the multiple sheet block 4 is provided on the front surface. For example, a prismatic block made of synthetic resin or the like forming the ruler portion 26 is attached to the front surface of the fork 23 of the fork-shaped stopper 18,
This prismatic block is extended on the upper surface of the side edge of the second conveyor belt 2.

When the ruler 26 intersects with the second fork-shaped pusher 12, it contacts one side surface of the multiple sheet block 4 and the upper surface of the side edge of the second conveyor belt 2, and transfers the multiple sheet block 4 to the belt 2. Set the position. That is, it functions as an extruding position setting means for transferring the multiple sheet block 4 to the central portion of the second conveyor belt 2.
