Abstract

PURPOSE:To prevent the collision of form sheets and the damage of the sheets by receiving the form sheet into a gate installed onto a belt and transporting it, in a registration apparatus which feeds the form sheets intermittently sent-out from a tray into the next process at a prescribed timing. CONSTITUTION:When a power source is turned ON, a belt 34 is driven, and the belt 34 is allowed to stop at a prescribed position by the control circuit of a control means 38 on the basis of the output of a sensor 40 for detecting the pass of the gate 35 on the belt 34. When a copy starting button is operated, the form- sheets intermittently sent from a paper feeding tray are accelerated by a slip roll 33 and sent into the arrangement area of the belt 34 in a form-sheet transportation passage 31. Before the form sheet reaches the A point in the transportation passage 31, the belt 34 is driven by the output of a form-sheet detecting means. Therefore, the form sheet is sent to a register roller 32 side, received by the gate 35 projectingly installed onto the peripheral surface of the belt. Then, the form sheet is sent by a register roll 32.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application 91f] The present invention relates to a registration device. The present invention relates to a registration device in which the paper is sent to a registration roll, and the paper is conveyed to the next paper processing step by the registration roll.

[Prior art]

Conventionally, there is a Registry Shore 'r% FJ in which paper that is intermittently sent out from a paper feed tray is sent to the next paper processing step at a predetermined timing. This conventional registration device is divided into two types: one type employing a register roll and the other type employing a register roll.

FIG. 1 shows a copying machine equipped with a conventional registration device employing register rolls.

In this copying machine, as the belt-like photoreceptor rotates 10 times, a charging corotron 2 first uniformly charges the belt-like photoreceptor 1, and then a flat flash exposure 3 applies a charge to the belt-like photoreceptor 1 using a platen. 4, an electrostatic latent image 6 corresponding to the image information of the original 5 set on the original 5 is formed, and then this electrostatic latent image 6 is visualized by the developing device 7, and then,
This L3T visual image is transferred by the transfer corotron 8 to the paper 1 (on the paper 1) supplied from the paper feed section 9. Further, in this copying machine, after this transfer, the belt-shaped photoreceptor 1 and the residual toner on the surface of the belt-shaped photoreceptor are electrically neutralized by the static eliminating corotron 11, and then The remaining toner is removed by a cleaning device +t12 to clean the surface of the belt-like photoreceptor, and then the surface of the belt-like photoreceptor is irradiated with a static elimination lamp 13 to completely eliminate the static charge. The belt-shaped photoreceptor is charged again. Below, repeat the above operation 1
-0 By the way, the registration device 14 in this conventional copying machine has a registration roller 16 and a slip roll 17'(L'' According to this registration device 14, after the copy start button (not shown) is pressed, the paper feed
The paper 10 sent out from A 18 by the paper feed roll 19 is sent to the transport roll 20, etc., and then sent to the slip roll 17 along the transport path 15.

The paper sent to the slip roller 17 is accelerated by the slip roller and sent to the registration roller 16. The first sheet of paper sent to the register roll 16 is sent to the transfer step 5, which is the next sheet processing step, by actuating a register roll and a driving electromagnetic clutch (not shown) at a certain timing. Note that the above-mentioned predetermined timing refers to the conveyance direction 11i1φ of the paper sent out from the register roll 16; l and JS of electrostatic latent image 6 on one belt-shaped photoreceptor! j-row direction side 1'ii,'
This is the timing at which these are matched in the transfer process. In addition,/! g In Figure 1, 21 is used in the transfer process, t6 is used to fix the transferred paper (11-2 printing device, 2
2 is a roll P1 (roll) for discharging the fixed-fixed paper to the paper discharging tray 23.

Tokoro C1 above and 1 like this r1 photocutting% &-L1 continuous &C 梠! 100 sheets of paper were being fed to the ia machine. [The above-mentioned sheet spacing varied, and as a result, the paper that had not been completely fed out from the register scroll 16 was replaced with the paper that was sent next. Collision, and then -(
, these papers were damaged by each other.

Also, as described in 1141J, some conventional registration devices use register gates. This registration device (not shown) has a register gate shown in place of the register roll 16 in the registration device 14 marked Ail, and the register gate is set in a predetermined position similar to the case of the register roll 16. The paper transport path 15 is opened and closed at the predetermined timing by operating at the timing shown in FIG. That is, in this registration 1 no-signing device, as in the case of the registration storage wrapping device 14, the paper accelerated and fed by the slip roll is once received by the register gate, and the paper is transported by the register gate. The paper that was received by the register gate when the path 1i1] was passed is sent out to the next paper processing step.

However, even in the case of a register storage unit using such a register gate, as in the case of the register storage unit ff14 using the register roll 16Y, when paper is intermittently sent out from the paper tray 18, it is busy. teeth,
The paper being received by the register gate collides with the paper being received by the register gate, thereby damaging each other.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a registration device that does not damage paper.

[Structure of the invention]

In the present invention, in order to achieve the above object, each sheet of paper 1 that is accelerated and fed by 1 slip roller is
A gate protruding from the belt catches it and transports it to the register roll.

〔Example〕

F1 Regarding the registration device according to the present invention,
This will be explained in detail with reference to accompanying drawings.

5) 2+'E+ shows an example of a registration device according to the BAK of the present invention.

In the registration device 3o of this embodiment, when the registration roll 32 and the slip roll 33 are installed at a predetermined interval on the paper conveyance path 31, the registration device 3o automatically
A belt 34 is installed between the roller 2 and the slip roll 33. The belt 34 has a plurality of gates 35 protruding from it, and is wound around boots 936 and 37. Here, the pulley 36 is loosely fitted to a shaft (not shown) that supports the register drive roll 3211. It has been installed. In the pulley 37, a pulley 37a is formed at -r4. In addition, this cashier storage Ron decoration 30 has a belt 3.
fl+lI lli to drive and control 4 as explained later.
l means 38. The control means 38 includes a stepping motor 38a, a control circuit (not shown), and the like.

Stepping motor 38aK)! , Goo! J 38b is installed, and a belt 39 is attached to pulley 38b and pulley 37a.
is wound around ℃.

That is, the power of the step motor 388 is applied to the pulley 38.
It is transmitted to the seat belt 34 via the b1 belt 39 and pulleys 37a, 37. As a result, the gate 35 of the belt 34 is moved along the paper layer feed path 31. In this registration device 30, the register drive roll 3
The same speed of 2a is V. The movement speed of gate 35 is y
o Same speed of slip-pinch four-wheel 33a 5Vn
In this case, each is set so that vo≦V G (V 8. In addition, in Figure 112:
, 32tl is the register pinch roll, 33b is the slip, "tK Wb roll, 40 is the gate 35 of the belt 34.
It is a sensor that detects

Next, the operation of this embodiment will be explained, and the advantages of this embodiment will be made clearer.

Now, I have a register storage device 30 like this.
When the power is turned on, the belt 3
4 is driven and the sensor 40 is 1lij J of the gate 35
N4 is detected, and based on the detection signal, it is stopped at a predetermined position by the control circuit of the control RA11 means 38.
Thereafter, when a copy start button (not shown) of the copying machine is operated, sheets are intermittently fed from a paper feed tray (not shown) to the slip +1-rule 33 (Z). Samo trap,
These sheets are accelerated by the slip roll 33 and sent to the belt 34 installation area R of the paper transport path 31.

At this time, the control circuit detects the paper accelerated and sent out by the slip roll 33 using a sensor (not shown), and the gate 35 of the belt 34 is detected before the paper reaches the point A pressure of the paper transport path 31. When the paper reaches the point A, the gate 35 outputs the start signal No. 18 to drive the step motor 38a. Then, the gate 35 feeds the paper to the register scroll 32 while stopping the paper receiving. When the paper reaches the register roll 32, the gate 35 is removed from the paper transport [1331]. At this time, an electromagnetic clutch (not shown) is activated to transmit power to the register drive roll 328, so that the register roll 32 nip the paper and send it to the next paper processing step. Here, the electromagnetic clutch operates in a manner similar to the case of the copying machine shown in FIG. It is operated by the control circuit at a timing when the full end in the advancing direction coincides with the full end during the transfer process. The gate 35 that has escaped from the paper transport path 31 is also detected by the sensor 40, and is stopped at a predetermined position by the control circuit, waiting for the next start signal from the control circuit.

In the above embodiment, the first stage 38 of the belt 340 is borrowed using a step motor 38a, etc., but the present invention is not limited to this, and the belt 340 damping means may be borrowed using a servo motor or the like. Of course, it is also possible to do this.If you do this, the gate 35 of the belt 34 will be
It becomes possible to freely change the moving speed of. As a result, for example, when a sheet of paper that has been received by the gate 35 and is conveyed gets stuck in the register roll 32, the moving speed of the next gate 35 is increased and the paper is quickly moved backwards (opposite to the conveyance direction). It is also possible to position the next gate 35 at a slight interval in the lateral direction). This completely eliminates the possibility of a sheet of paper following from behind colliding with a sheet of paper in front of it. In addition, by adopting the above servo motor, the gate 35 can be used as a cash register.

If the timing of reaching the star roll 32 is set as the actuation timing of the electromagnetic clutch of the register drive roll 32, the electromagnetic clutch becomes unnecessary and it becomes possible to continuously drive the register roll 32 to rotate. In this way, the feeding of paper from the registration scroll 32 is interrupted.

Because it is possible to carry out 5 continuous operations, even if you want to transport paper to J1 High School or VA, you can easily handle it every month.

〔Effect of the invention〕

As explained above? 2. Since the register storage Ron device related to ``Main Departure'' is configured to transport the paper by receiving it at the gate, there is no possibility that the preceding paper may track or collide with the preceding paper. However-)
Be able to send the paper to the next paper processing process without damaging it.
