Abstract

PURPOSE:To provide easy method of taking out sheets, that should not require fatigue of the operator, by pinching the sheets stacked in each bin by a gripper mechanism, transferring them along a rail, and by accommodating these transferred sheets in an extra pin arranged above the uppermost bin. CONSTITUTION:A gripper mechanism 6 for stacking sheets plunges into the uppermost bin 2 in the condition with its gripper nail 22 opened to locate the edges of sheets stacked in the bin 2 between gripper rails 21, 22. Then an end 25 of the nail 22 is collided with a boss 16 arranged at the final point of a guide rail 8 to rotate the nail 22, for gripping the sheets. In this condition of the sheets gripped, a motor 11 is put in operation to move the gripper mechanism 6 and to draw out the gripped sheets from the bin 2 by felling down the sheets slip-off preventive wall 2' of the bin 2. The sheets thus drawn out are transferred onto an extra bin for accommodating of transferred sheets 3, and the motor 11 is stopped when the gripper mechanism 6 has returned to the start point of the rail 7. Then the abovementioned end of nail 22 is collided with a boss 15 of rail 7 and the nail 22 is opened to let the transferred sheets fall into the extra bin, which are then moved toward the operator.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for sequentially transferring the next stack of sheets contained in each bin of a sorter to other bins provided above the uppermost bin of the sorter.

Most sorters attached to copying machines, etc., except for large or special types, generally have paper storage racks (hereinafter referred to as "top pins") lined up vertically. When picking sheets, especially when taking sheets from the lower bin, the operator is forced to take a forced posture, which not only impairs paper production but also often causes physical problems for the operator.

In order to solve this problem, a type of sorter has been proposed in which each bin is raised as a whole at the same time as the paper storage vessel U1 is finished, but there are problems such as an increase in the size of the sorter.

The present invention has been made in order to completely eliminate the drawbacks of the conventional sorter as described above. A stacked paper grit lever mechanism is provided that passes through the bins and hangs down along one edge of each bin of the sorter other than the paper input line, and that the rails integrally nip and convey the stacked paper stacked in each bin. The purpose of the present invention is to provide a stacked paper transfer device for a sorter in which 712 rows of paper can be freely attached.

Hereinafter, the tree will be explained in detail with reference to Figure m1 without showing examples.

! Figure 1 is a schematic side view showing an embodiment of a stacked paper transfer device for a sorter according to the present invention.

That is, sheets fed from a soaker 1t and a first copying machine, etc. (not shown) are sequentially fed into each bin 2, 2, etc. of a sorter by a Wy feeding sorter (not shown). This > V work is performed a predetermined number of times in each of the bins 2.2, . . .

Remove the accumulated paper from each bin, especially from the lower bin.
As mentioned above, the act of forcing the operator into an unreasonable position is the cause of occupational disability such as back pain.

In order to solve this problem, in the present invention, first, a transfer paper storage bin 3 is provided above the topmost bin 2, in order to sequentially transfer the sheets accumulated in each bin as one piece to the vicinity of the top of the sorter.

Next, the stacked paper gripper mechanism 6 will be explained.

Figures 2 (, ), (l) and (c) are the states of the present invention, respectively.
FIG. 1 is a side view, a front view, and a plan view showing an embodiment of a gripper mechanism that is a main component of a vertical loading transfer device.

That is, this gripper machine (146 is designed to run while gripping the 7-lunge section of the rail T having a T-shaped cross section) - 4 rollers 18, 18, 18, 18, . The roller 19 that comes into contact with Kfi has gripper claws 21 and 22 attached to the tip of a travel block 20 provided, and the claw 21 extends the tip of the Nuhi row block 20 and is integrated with this, and other The pawl 22 is configured to be freely rotated m11 relative to the front V pawl 21 by a hinge 23.

Further, the paper gripping surfaces of both claws 21 and 22 are knurled 24, and the l! 111 Regarding the hinge 23, an opening/closing driving claw 25 is provided at the other end,
This can be engaged with protrusions 15 and 16 provided on the rail T and the guide rail 8.

In addition, springs 26 and 26 are provided on both sides of the pawl 22 in order to bias the rotary pawl 22 to one of two positions, open or closed.
is provided to form an l-glue mechanism.

Numeral 27 is a stopper for the rotating claw 22, and 28 is a stopper for each of the bins 2.2, which allows the claw of the gripper mechanism to enter.
. . It is a fist cut, and the stacked paper is gripped between the claws 21 and 22 through this cut. Finally, the structure of the cable guide 12 and the rail T will be briefly explained.

FIGS. 3(IL) and 3(b) are a side view and a front view of the front F cable guide 12, respectively.

Immediately, assemble the cable fist guide running block 31 so that the rail T can be gripped by a pair of rollers 29 and 29 that abut on both sides of the flanges of the rail 7 and the abutting roller 30 on the back side of the 7 flange, and set it coaxially with the rollers 29. A cable guide roll 32 can be rotatably mounted on the outside of the block 30.

Further, a stopper 33 is attached to the block 30 so that the stopper 33 can come into contact with the protrusions 13 and 14 so that the rail travels only between the protrusions 13 and 140 provided at the starting point and the curved portion of the rail.

By doing so, the stacked paper gripper mechanism 6
No matter where the cable 10 is located on the rail T and the guide rail 8, it is possible to smoothly pay out or wind up the cable 10 and transfer it.

Furthermore, FIG. 4 shows the rail 7 and the guide rail 8.8,
. . . is a diagram illustrating the shape of the connection portion, and at the connection point between the two, the traveling rollers 18, 18, . . . A part 34 of the flange is provided to allow smooth transition to the guide rail 8.

Although this flange cutting point 34 corresponds to the bottom bin of the sorter, it is not necessary to provide it at all positions except for the γ value.

The stack H1 sheet transfer device of the present invention constructed as described above operates as described below.

Now, when the last paper is loaded into the second bin 2 of the soak, the brake of the morph 11 is released by a signal from a paper input sensor in the bin (not shown), and the starting point of the rail 7 is Then, the stacked paper gripper mechanism 6, whose gripper claws 22 are opened by the action of the protrusions 150 provided on the rail 7, starts sliding on the rail T due to its own weight.

At the same time, the guide rail 8 corresponding to the topmost bin 2 is connected to the rail 7 by driving a rotary solenoid (not shown).

In this way, the stacked paper gripper mechanism 6 plunges into the topmost bin 2 at the stroke ρ+4 when the gripper claws 22 are opened, and the end of the paper stacked in the bin is moved between the gripper claws 21 and 2.
It will be located between 2.

At this time, one end 25 of the pawl 22 collides with the protrusion 16 provided at the end of the guide rail 8, rotates the leading pawl 22, and grips the stacked paper.

The gripping force of the seedlings and stacked paper depends on the tension of the springs 26 and 26 of the front F toggle mechanism.

Further, when the stacked paper gripper mechanism 6 reaches the end point of the guide rail 8, the front photo sensor operates, and the morph 11 is controlled to be driven with a slight time delay depending on the input signal. The stacked paper is pulled out from the bin by pressing the paper slip-preventing wall 2' of the bin 2, which is gripped by the stacked paper gripper mechanism 6, and transferred onto the transmission paper storage bin 4.

When the stacked sheet gripper mechanism 6 returns near the starting point of the rail TO, the photo sensor 1T detects this and uses the signal to actuate the brake of the morph 11 rJJ1, and at the same time removes the topmost bin and the next stage. The guide rail 8.8 corresponding to the bin is moved toward and away from the rail T in preparation for the next culm.

Also, since one end 25 of the grip claw 22 of the stacked paper gripper mechanism 6 collides with the protrusion 15 of the front iC rule T and opens the claw 22, the transferred paper falls into the transfer paper storage bin 3 and Move to the operating side.

Below is the previous ttE! The sheet gripper mechanism 6 repeats the same operation and can sequentially transfer the stacked sheets in each bin 2.2, . . . into the transfer sheet storage bin 3.

In this way, the operator can perform the above rotation without taking an unreasonable posture! = The paper transferred into the paper storage bin 3 may be pulled out twice and stapling may be performed.

In addition, the copy paper stored in the soak bin connected to the copy mode generally has the copy side facing down, but the paper transferred to the transfer paper storage bin 3 is reversed, so the trouble of reversing the paper stack is eliminated. It has very good operability due to its tightness.

However, the present invention is not necessarily limited to the mechanism as described above.
For example, as shown in FIG. 5, a rotatable hollow arm 34 is inserted into the traveling block 20, and a telescopic middle q-axis 35 is inserted into the arm 34.
The guide rails 8.8, . . . may be removed by providing gripper claws 21 and 22 at the tip of the intermediate shaft 35.

At this time, the rotational claw 22 and the hollow arm 340 rotation axis of the gripper are made into torsion bars 36 and 37, and the vertical claw 22 is directed in the H-+ direction, and the middle 9th member 34 is in the front position.
It is biased in a direction parallel to the lever 7.

Further, the hollow shaft 35 expands and contracts in the middle 4b-m 34.
The coil spring 3B""c is biased 17 toward the shortening side, and a rod 40 coupled to a memory alloy coil 39 is placed behind it.

Furthermore, the opening of the middle punching arm 34 and the traveling block 20 which rotatably engages the same, and the space between the rotating claw 22 and the middle nine shaft 36 to which it is attached are also formed using a shape-memory alloy. They are connected by coils 41 and 42.

Incidentally, 43 and 44 are stoppers for regulating the recirculation range of the medium punching arm 34, and 45 is a micro switch for emitting signals such as the stop position of the front CC stacking paper gripper lateral G.

By deceiving the stacking paper gripper Isodan 6, while running on the rail T, the front rotation ■! 1 freely movable hollow column 34 maintains a position parallel to the rail 7, and when it reaches a position corresponding to a predetermined bin, it is stopped by a signal from a self-recording micro switch 45, and at the same time the shape memory alloy coil 39. There will be 3 electrical currents at 41 and 42.

As is well known, shape memory alloys can be made by heating with electricity.
Since it contracts and returns to its original shape, generating tension at that time, the hollow arm 34 resists the twisting and bending force of the torsion bar 37 and rotates to the position shown in FIG. , the rod 40 also moves forward to extend and close the hollow shaft 35 with the gripper. Furthermore, the mark 1 claw 22 of the gripper also closes against the torsion bar 36 to grip the stacked paper.

In the above description, the transfer paper storage bin 3 is provided separately from the normal bins 2, 2, . . . , but the present invention is not necessarily limited to this. Also serves as the transfer paper storage bin (7 may also be used).

Since the present invention is constructed and operates as described above, it only requires a relatively simple mechanism to be used for soaking, thereby improving the operability of the sorter without increasing the size of the sorter body, and reducing operator fatigue. It is of great help to children in preventing the physical disability Crf caused by taking an unreasonable posture.
