Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorter for sorting and assembling recording paper discharged from a recording device such as a copying machine, a printing machine, etc., and more specifically, the present invention relates to a sorter for sorting and assembling recording paper discharged from a recording device such as a copying machine or a printing machine. The present invention relates to operating means for a receiving guide plate for receiving recording paper.

Conventionally, when a recording device creates a large number of records assembled from a large number of sheets, the recording sheets taken out from the recording device are sequentially received by a receiving device of a sorter, and then transferred to a recording paper transport device. During the transfer, the receiving guide plate installed at the recording paper receiving port of each bin of the distributing device consisting of a large number of bins is operated to collect the recording paper into each bin in an orderly manner and assemble the paper into the bins to the maximum number of bins. Only a large number of records have been kept.

In order to operate the receiving guide plate, a solenoid is attached to each bin, and the solenoid is activated by a command from the control device of the sorter or recording device, and the receiving guide plate is operated by connecting the solenoid to the solenoid. It will be done. This method requires the same number of actuators, such as solenoids, as the number of bottles, and is extremely expensive.

Alternatively, a method is known in which a receiving guide plate provided at a recording paper receiving port of a bin aligned in a line is operated by a single dog that moves parallel to the receiving port. In this method, there is a pause in the guide operation between the end of the series of guide operations that operate the receiving guide plate and the return to the start point, and the continuity of the guide operations is lacking, making it difficult to copy a large number of recent recording sheets. It is difficult to adapt it to high-speed recording devices.

In view of the above circumstances, it is an object of the present invention to provide a receiving guide plate actuating device W in a sorter distribution device that is inexpensive, simple, has good continuity of guide operation, and is compatible with recent high-speed recording devices. The purpose is

The above-mentioned object of the present invention is to provide a recording paper distributing device of a sorter that picks up recording paper discharged from a recording device and distributes it to a plurality of bins, in which a plurality of protruding members that travel This is achieved by means of a sorter receiving guide plate actuator which places the receiving guide plate of the paper receiving bin in a receiving position.

Hereinafter, the operation of the receiving guide plate of the sorter of the present invention will be specifically explained with reference to the embodiments shown in the drawings.

FIG. 1 is an overall external view of an example of a sorter according to the present invention, FIG. 2 is a sectional view of the same sorter, and FIG. 3 is an enlarged sectional view of the essential parts of the sorter.

In FIGS. 1 to 3, the sorter is equipped with a cart 1 that can be moved to any position, and a vertical support frame 2 is erected on the cart 1. ．． 4. A receiving device, a transfer device and a dispensing device, respectively indicated at 5, are installed.

The receiving device f3 includes a flat box-shaped base 6 whose base is supported by the support frame 2.

The inclination angle can be adjusted according to the height of the paper discharge port E of the recording apparatus C by an adjustment mechanism (not shown). Two pairs of pulleys 7.8 are built inside the base 6, and an endless conveyor belt 9, a portion of which is exposed on the top surface of the base 6, is stretched between these pulleys 7.80. It will be done. Then, on the base 6 whose tip is tilted down, there is a shaft 10 (
A main paper discharge tray 11 which can be opened is located centering on the main paper discharge tray 11 (FIG. 1). A plurality of driven rows 212 are supported at the bottom of the main paper discharge tray 11 and are rolled into contact with the upper surface of the conveyor belt 9 . Therefore, the recording paper from the recording device C received by the receiving device 3 is conveyed while being held between the conveyor belt 9 and the driven roller 12. Further, as shown in FIG. 2, the recording paper discharged from the paper discharge port E of the recording device C is placed at the front end of the receiving device 3 whose leading end faces the paper discharge port E of the recording device C. 3
Alternatively, a deflecting means 13 for distributing the paper to the main paper discharge tray 11 is provided. The deflection means 13, which can be tilted about the shaft 14 of the base 6, has a top plate 15 that forms a part of the main paper discharge tray 11, and when the deflection means 13 is flipped up, the top plate 1
5 and a lower plate 16 that guides the recording paper from the paper discharge port E to the receiving device 3.

The recording paper conveyed by the receiving device 3 is transferred to a vertical transfer device 4 connected to the rear end of the receiving device 3. That is, the transfer device 4 has a mounting plate 18 that can be opened as shown by the imaginary line in FIG. Several endless conveyor belts 21, which are partially exposed on the inner surface of the mounting plate 18, are wrapped around the fixed pulleys 19 and 20. On the surface of these conveyor belts 21, small conveyor rollers on horizontal shafts 22 (FIG. 8), which are equidistantly hung over the support frame 2 so as to be vertically adjacent to each other, are rolled into contact.

In order to maintain the rolling contact state of these conveyance rollers n, a small auxiliary roller U located inside the conveyance belt 21 is attached to the mounting plate 18 in correspondence with the conveyance rollers. These auxiliary rollers are each supported by shafts 27 that are stretched between the grooves 26 of the frame 25, as shown in the third figure. These shafts 27 are pressed in the direction of the corresponding conveyance rollers 23 by projections 28 of the frame 25 and tensioned wires 29 alternately hung on each shaft 27 above the main paper discharge tray 11. is provided with a dispensing device 5 whose base is fixed to the support frame 2.

This distribution device 5 has a base fixed to the support frame 2 in a state corresponding to each of the transport rollers n, and has a plurality of bins (sheet discharge trays) Bi (generally referred to as B) aligned in the vertical direction.
Equipped with

There is a reception guide plate Gi at the entrance of each bin B1 mentioned above.
(as shown in the figure, collectively referred to as G) are located respectively.

These receiving guide plates (hereinafter referred to as gates) G are fixed to shafts 32 installed on the support frame 2, and are coupled to lever blades provided at the shaft ends of these shafts 32. Therefore, by rotating the lever wings around the shaft 32, the gate G is operated and the lever blades are arranged with a small difference, or the tip thereof is formed into a fork shape.

Therefore, in Figure 36, by rotating the lever 33 clockwise, the tip of the G (g) is made to intersect the recording paper conveyance path composed of the conveyance belt 21 and the conveyance roller O, and the vertical direction of the recording paper is moved. The gate G adjusts the posture to receive the recording paper.

When the recording paper is conveyed there, the recording paper is received into the corresponding bin B.

FIG. 4 is a side view for illustration purposes only of a sorter receiving guide plate actuating device (hereinafter referred to as gate actuating device) according to an embodiment of the present invention. Although omitted, the gate actuating device of the present invention includes a support frame 2.
This is a component device of the transfer device 4 built into the gate G, which rotates a lever 33 provided at the end of the shaft 32 while fixing the gate G to receive the recording paper described above into the gate G. A plurality of protruding members (hereinafter referred to as dogs) are used as a mechanism for providing either a closed posture in which the conveying path of the bin B is opened and the recording paper receiving port of the bin B is closed by the gate G.

In one embodiment shown in FIG. 4, 30 is a gate actuator. In this system [30, an endless belt 3 stretched around pulleys 34 and 35 whose rotating shafts are fixed to the support frame 2.
6, a dock Di (D! and D2 in the example) and a sensor actuator 5t (generally referred to as S) are provided with the shafts 32 to which the respective gates G are fixed, and a dock Di (D! and D2 in the example) is provided.
! and D2 are provided at two symmetrical points that equally divide the entire length of the belt 36, and no sensor actuator S is provided at the position where the dog is installed.

Further, a sensor 37 for detecting the sensor actuator S is fixed at a fixed point on the traveling path of the belt 36, and a detection signal is sent to a control device 38, which drives the pulley 35 based on the detection signal and the built-in program. 39. Note that the pulley 34 is driven by a pulley 35.

Belt 36 of gate operating device 30 configured in this way
When the dog Dl is moved around by the pulley 35, for example, when the dog Dl comes into contact with a lever 33 fixed to the shaft 32 of the gate GnI, the gate Gm assumes a recording paper receiving attitude. Other gates that the lever 33 does not contact, such as gate Gt or gate 0M, are in a closed position.

When the gate is in the receiving attitude, the sensor 37 detects the sensor actuator S corresponding to the gate Gm, and the recording paper is transferred to the bin BIn.
The belt 36 is stopped until the belt is stowed, and after confirming that the belt is stowed, the dog starts cruising again and the dog DI reaches gate G. When the lever 33 corresponding to the lever 33 is released, the lever 33 uses a return mechanism (not shown) such as a return biasing spring to close the gate GIT1. If the records to be distributed end at the bin axis, even if the dog comes into contact with the lever 33 corresponding to the remaining bins Bm+1 to BM, the belt 36 will continue cruising according to the program instructed by the control device, and the dog D1 will Stop position PE
reach. At the same time as the dog D1 reaches PE, the dog D2, which is located at a symmetrical position in terms of the length of the belt 36 and the dog D1, is automatically and inevitably located at the standby position PO, which is detected by the control device and the belt 36 is stopped. The standby position may be detected by a commonly used method, such as providing a dedicated sensor for detecting the dog, or changing the pitch of the counting time by changing the installation pitch of the sensor actuators, and detecting based on the difference.

At the time when one of the dogs has finished conveying and distributing the recording paper to each bin by the dog and is waiting in the standby position, the document to be recorded is being replaced in the recording apparatus.

Therefore, in the present invention, the guide of the recording paper to the bin is always in a standby state without imposing any restrictions on the recording speed or recording operation of the recording device, and the operation continuity is good. The drive does not require an expensive special motor such as a pulse motor that is required when using a solenoid, and it is sufficient to use an inexpensive inductor motor or shaded motor, and many expensive solenoids are not required. At the same time, the cost of the sorter can be significantly reduced and the size and size of the sorter can be reduced.

The dog and the sensor actuator may be provided on either the outer or inner circumference of the belt. However, if provided on the inner periphery, a dog or sensor actuator escape link should be provided on the circumferential surface of the pulleys 34 and 35 depending on the height to avoid damage and provide smooth belt travel. There is a need, and methods commonly used in mechanical engineering can be used for that purpose.

Next, we will explain the present invention by taking as an example a case where a record of m copies (serial number code 1) distributed from -10 = number of pages n (serial number code j) is created in a sorter having a dispensing device with M bins. The operation of the gate actuating device according to the above-mentioned embodiment will be explained with reference to the flowchart shown in FIG.

First, the number of copies (m) of records to be distributed and the number of pages (n) to be distributed are entered into the control device, and the control device operates the booby in response to a recording paper ejection signal from the recording device, and when the dog comes into contact with the lever, the gate is placed in the receiving position. A sensor detects this using an actuator, and the pulley is stopped until the recording paper is completely stored in the bin.When the recording paper is completely stored in the bin, the number of copies is counted by one and compared with the predetermined number of copies m. (Processing above (
1) to (7) and judgments [1] and [2]). Records of a certain page are transported and distributed to bins until the number of copies reaches m,
When the dog reaches the stop position [PE], the dog, which had previously stopped each gate of each bin, does not stop at the remaining gates and other dogs are sent to the standby position. This \ advances the page number j by one and reaches the predetermined page number n.
If j is less than n, judgment is made again (1
