Description

[Detailed description of the invention] The present invention relates to improvements in automatic stacking machines for cut paper, etc.

Conventional automatic loading machines mainly load and unload paper sheets, etc. in groups, and when loading multiple groups in parallel, the multiple groups are placed in close contact with each other on the transfer table. Loading and unloading is performed in the same way as in the case of , and it is difficult to unload multiple groups separately.

In addition, in conventional automatic loading machines, when cut paper, etc. is placed on the transfer table, the transfer table lowers or rises to the level of the upper surface of the loading surface at the loading position, and then moves to the loading position, where the loading device picks up one piece. Cut paper, etc. is loaded onto a pallet or loading platform.
In order to lower or raise the transfer table to the level of the upper loading surface that changes depending on loading, the transfer table is cantilevered by its drive device.

Therefore, with conventional automatic loading machines, there is a great risk of being caught between the descending and ascending transfer table and the cutting machine, etc., and it is difficult to take complete protection measures, and the transfer table changes. It takes a long time to move up and down to the loading level, resulting in low loading efficiency, and because the transfer table has a cantilevered structure, it bends easily, which limits the weight of cut paper, etc. that can be loaded at one time. There is also the problem of.

The present invention has been made to solve the above-mentioned problems of conventional automatic loading machines, and the automatic loading machine of the present invention has the following features:
A transfer table is provided which is supported on both sides by a traveling table, and lifts and moves from a predetermined height to a predetermined height to horizontally receive cut paper, etc. from a cutting machine, etc., and sends the cut paper, etc. to a loading device. a movable ruler that regulates the position of the cut paper, etc. placed on the transfer table; and a movable ruler that contacts the transfer table and moves downward and horizontally to push the rear end of the cut paper, etc. on the transfer table. It is equipped with a drop-in gate and a movable holding foot that receives the front end of the pushed cut paper, etc. and pinches the cut paper, etc. between the drop-in gate and the cut paper, etc. that are caught when the transfer table retreats horizontally. The present invention is characterized in that it consists of a loading device that allows sheets to fall, and a loading device that is equipped with an elevating table to receive fallen sheets and the like, and that allows the sheets to be carried out.

Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 is a side view showing one 9U of the automatic loading machine of the present invention;
FIG. 2 is a plan view, FIG. 3 is a front view from the side of the unloading device, and FIG. 4 is a front view showing the staggered stacking state.

In the figure, reference numeral 1 denotes a transfer table whose surface is an air blowing table, and is supported on both sides by a traveling base 2 by an elevating spindle 1a.

2a is the running wheel of the running platform 2, 2b is the straddle foot, and the running platform 2
For example, it is supported at three points: straddle legs 2b provided at two places and running wheels 2a, and the running wheels 2a roll on the rail 3, and the straddle legs 2b ride on the linear bearings 4. By moving, it moves left and right in FIG. 1 along the linear bearing 4.

The movement is performed by a motor-driven chain (not shown).

Reference numeral 5 designates a cable for supplying power to a motor (not shown) provided on the transport table 2 that moves the lifting spindle 1a of the transport table 1 up and down.

Reference numeral 6 denotes a movable ruler, which can be rotated by a shaft 6a, and when the transfer table 1 is at a predetermined position to horizontally receive the cut paper 8 etc. from the cutting machine 7 etc., it pivots downward and the front surface of the ruler plate 6b is transferred. This serves as a vertical abutment surface that regulates the depth position of the cut paper 8 and the like on the table 1.

Lateral abutment plates 6c are attached to the ruler plate 6b, and when a plurality of lateral abutment plates 6c are attached as shown in the figure, the horizontal abutment plates 6c are also regulated by applying the sides of the cut paper 8 or the like to each of the plurality of lateral abutment plates 6c. The cut sheets 8 and the like can be placed in parallel at intervals.

Note that this movable ruler 6 is equipped with a shifting mechanism for staggered stacking.

That is, a groove wheel 6d is provided on the shaft 6a on the opposite side of the swing drive source, and an eccentric plate 9a driven by a deceleration motor 9 is engaged with a circumferential groove of the groove wheel 6d.

Therefore, when the deceleration motor 9 is moved to rotate the eccentric plate 9a, the shaft 6a moves in the thrust direction, which changes the position of the lateral abutment plate 6c. If you move 9, it will be staggered.

10 is vertically lowered from the position shown by the solid line in FIG. The drop gate 11 of the loading device returns to the solid line position in the opposite direction from the previous position after retreating, and 11 is a movable presser that regulates the front surface of the cut paper 8, etc. and presses the top surface of the cut paper 8, etc. loaded into the loading device. The foot is pivotable by a shaft 11a driven by a deceleration motor 12.

13 is a lifting table of the loading device, and a lifting screw 13a
The lifting N is raised and lowered by the lifting guide roller 13b.
, 13b'.

14 is a shipping pallet placed on a lifting table.

Next, the operation of the above configuration will be explained.

The starting position is the state where the transfer table 1 and the traveling base 2 are at the solid line positions in FIGS. As already mentioned, the movable ruler 6 is in a state where it can swing downward and regulate the position of the cut paper 8 and the like.

In the state of loading from the loading device, the movable presser foot 11 of the loading device is in the state of being swiveled up to the position indicated by the two-dot chain line in FIGS. 1 and 3, and the lifting table 13 of the loading device is lowered to the lowest end. in a state.

Therefore, when newly loading, lift table 13
The shipping pallet 14 is placed on top and a start button (not shown) is pressed.

Then, the movable presser foot 11 of the loading device swings down to the solid line position, and at the same time, the lifting table 13 is raised by the lifting screw 13a, and the upper surface of the unloading pallet 14 comes into contact with the presser claw 11b of the movable presser foot 11, and the lifting table 13 is raised by the lifting screw 13a. Pushing up will stop the rise.

On the other hand, air is blown out from air blowing holes (not shown) on the surface of the transfer table 10, so that the cut paper 8 and the like can be easily moved on the transfer table 1.

In this loading standby state, the cut paper 8 and the like are transferred from the cutting machine 7 and the like onto the transfer table 1.

The cut paper 8 etc. transferred onto the transfer table 1 is moved by a movable ruler 6.
As mentioned above, in the case shown, the light beam is placed in a fixed position.

Then, when a loading start button (not shown) is pressed, the air blowing from the transfer table 1 stops, and at the same time, the traveling platform 2
The transfer table 1 is moved to the right until it reaches the position shown by the two-dot chain line in FIG.

When the retreat is completed, the movable ruler 6 is turned up to the position shown by the two-dot chain line, and when it no longer interferes with the forward movement and rise of the transfer table 1, the carriage 2 starts moving to the left. Raise the transfer table 1.

Then, the movement of the transfer table 1 stops at the two-dot chain line position.
The carriage 2 moves forward by moving to the left, and the carriage 2 stops when it reaches the position indicated by the chain double-dashed line where the tip fork of the transfer table 1 also protrudes beyond the movable holding foot 11.

Thereby, the cut sheets 8 and the like on the transfer table 1 are brought to the loading device.

The drop gate 10 of the loading device is in the raised position shown by the solid line in FIG.
When the carriage 2 stops, it descends until its lower end touches the surface of the transfer table 1.

At the position where it has finished descending, the drop gate 10 is in a state where it can further descend to a certain height due to its own weight,
Therefore, it is in contact with the surface of the transfer table 10 due to its own weight.

The drop gate 10 that has been lowered then moves forward, pushes the rear end of the cut paper 8, etc. on the transfer table 1, brings its front end into contact with the movable holding foot 11, and stops.

Although not shown, the contact surface of the movable presser foot 110 is
The cut paper 8 can be elastically displaced in parallel.
The position in the loading device is the advanced drop gate 1.
Regulated by 0.

Note that the blowing of air from the transfer table 1 is resumed as the drop gate 10 moves forward.

When the drop-in gate 10 stops, the carriage 2 starts moving to the right, and the transfer table 1 moves backward, and when its tip fork reaches the position of the drop-in gate 10,
The cut paper 8 and the like fall from a state where they are held between the movable holding foot 11 and the dropping gate 10 onto the pallet 14 placed on the elevating table 13 of the unloading device and placed at an i'' position.

At this time, the drop gate 10 lowers due to its own weight as the transfer table 1 comes off, and guides the cut paper 8 and the like to accurately fall into a fixed position.

Making the contact surface of the movable presser foot 110 an elastic displacement surface is also effective in accurately dropping the cut paper 8 and the like.

The tip fork of the transfer table 1 drops into the gate 10
The drop gate 10, which has come off and lowered, begins to retreat following the transfer table 1.

When it reaches its original lowered position, it rises and returns to its initial position and stops.

The transfer table 1 and the carriage 2 follow a stroke opposite to the loading stroke, return to their initial positions, and stop.

On the other hand, when the dropping gate 10 begins to retreat, the movable presser foot 11 rotates slightly clockwise in FIG. do.

As a result, the dropped paper sheets 8 and the like are completely placed on the unloading pallet 14.

When the movable presser foot 11 stops, the lifting table 13
is the upper surface of the loaded cut paper 8 etc. or the movable presser foot 1.
It is once lowered so that it is below the position of the presser claw 11b of No. 1.

At that stage, the movable presser foot 11 pivots back to the original solid line position.

Then, the elevating table 13 that has been lowered once rises and
The upper surface of the loaded cut sheets 8 and the like pushes up the presser pawl 11b of the movable presser foot 11, thereby stopping the paper.

With the above steps, the loading of the first stage is completely completed, and the next loading can be carried out in the same loading standby state as the first stage.

Therefore, if the cut paper 8 etc. is placed on the transfer table 1 again and the loading start button is pressed, the second stage loading will be performed in the same manner as described above, and by repeating this, loading will be performed one after another. .

Then, as the loading progresses, the elevating table 13 of the unloading device
When the load starts to fall below a certain height, the loading drive of the carriage 2 etc. cannot be started even if the loading start button is pressed next time.

Therefore, by pressing the loading button, the movable holding foot 11 of the loading device is swiveled upward, and at the same time, the elevating table 13 of the loading device is lowered to the lowest end, and the loaded Asahi cut paper 8 and the like are moved together with the pallet 14 by a forklift or the like. I will have to take it out.

However, the removal of the cut sheets 8 and the like is not limited to the above-mentioned stage when the loading drive is no longer performed, but can be performed from any loading standby state.

The above is a case where the cut sheets 8, etc. are loaded and unloaded uniformly without any loading stage, but if they are loaded separately for each loading stage so that they can be easily taken out, as mentioned earlier, loading each time is as follows. At this time, the shifting mechanism of the movable ruler 6 is controlled by the deceleration motor 9.
It can be made to work by driving the .

FIG. 4 shows the state of the staggered stacked cut paper thus loaded.

In addition, 15 shown in FIG. 3 is a photoelectric type safety device, and if a human body etc. enters the position where the tip fork part of the transfer table 1 protrudes beyond the movable holding foot 11 of the loading device,
The machine is stopped so that the transfer table 1 is not moved forward and the movable presser foot 11 is not rotated.

As mentioned above, in the automatic loading machine shown in the example,
Cut paper, etc. can be loaded in parallel so that they can be loaded separately, and the transfer table is supported on both sides by a traveling platform, so it rarely bends even if the weight of cut paper, etc. is large. By installing a hanging cover at the point where the transfer table contacts the table of the cutting machine, etc. to prevent objects from entering below, there is no danger of objects getting caught between the transfer table and the table of the cutting machine, etc. Many excellent effects can be obtained, such as complete prevention, short transfer time, high loading efficiency, stable and accurate loading, and staggered stacking.

Note that the present invention is not limited to those that can be stacked in parallel;
The present invention can also be applied to piled items, and is not limited to items having staggered stacking means.

Further, the movable ruler is not limited to one that pivots, but may be one that moves in parallel in the vertical direction or the horizontal direction so as not to interfere with the movement of the transfer table.
