Description

TECHNICAL FIELD The present invention relates to a display method for a stacking device that displays the full state of the stacking section in a stacking device that stacks output paper sheets from a copying machine, a laser beam printer, or the like.

BACKGROUND ART In a loading device having multiple loading sections, when two or more loading sections are fully loaded, it is common to display which loading section should be taken out first and the order in which the stacked sheets are taken out. 17 It's coming. 7i+! is a method for displaying the stacked paper removal order. (Gumen) Some devices used LED indicators to display the order of removal, but they were difficult to see and led to erroneous operations. The secondary display control was also complicated, and the cost was unavoidable.

Purpose The present invention aims to eliminate the two drawbacks, and makes it possible to identify the order of unloading of the loading section of the loading device when the specified amount of loading has been carried out by means of a display means of the loading section, so that the loading section can be unloaded at the earliest point. The purpose of the present invention is to propose a display method for a loading device that allows processing to be performed more easily than a loading section that requires.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram schematically showing a general conveyance path of a loading device according to an embodiment of the present invention. The explanation will be given below based on this figure.

Paper fed from a cassette 2 loaded into the printer 1 has an image developed with toner transferred to it by a photosensitive drum 3, undergoes a known fixing process, and then is transferred by a paper roller 4 with the image side facing up. It is expelled.

The ejected paper is transferred to a stacking device (hereinafter referred to as stacker) 5
will be sent to. Paper is inserted into the input section of the stacker 5 by a pulley 20 and a press roller 19, and is transported horizontally in the direction of the arrow by a transport bell I.6. There is a horizontal deflector 7 at the end of the belt, and by activating this horizontal deflector 7, a solenoid 29 connected to the horizontal deflector 7 is energized to determine whether the belt is to be sent further horizontally or vertically. controlled by the presence or absence of

In FIG. 1, the paper is shown being fed vertically downward.

The paper is transported by a transport guide 8 and a feed roller, and is transported by a movable vertical deflector 10a and a fixed vertical deflector 10.
b leads to two loading areas. In Figure 1,
The solenoid 30 connected to the vertical deflector 10a is in a de-energized state, and the paper is not branched at this deflection section, but is sent downward, branched to the left by the vertical deflector lOb, and taken out by the roller llb. The conveyance heald 6, drive roller 9, and discharge rollers 11a and llb are controlled by a drive morph 27 via a drive transmission means (not shown) at a speed of 10% to 10% higher than the conveyance speed of the discharge C-roller 4 of the printer 1.
It is being driven at a 20% speed increase.

Now, in FIG. 1, output paper 1h stacking units (hereinafter abbreviated as deck units) are distributed to two locations, A and B, on a regular basis. Two wooden drawer rails 18a and 18b for deck parts A and H
(hereinafter suffixes a and b are omitted) are connected by a loading plate 17, and there is a positioning member (not shown) on the plate 17, and the paper container 1 is attached to the positioning member.

The pallet 13 on which paper is loaded is slidable, and when the pallet 13 touches the bottom of the container, the height of about 20
A gap of mm is opened, and the tip of the fork of the elevator device 14 for moving the barrette 13 up and down can freely move in and out of this gap.

When the pallet 13 on the fork is not loaded with paper, it reaches a specified height J: -J's and then stops.

Paper output from the paper ejection roller 11 with the print side facing down is
The alignment guide 16 regulates the conveying force at its own end and prevents it from becoming loose.
Descending to -13J-. When the paper surface detection sensor (not shown) reaches a certain height or higher, the sensor output drives the elevator motor 28 to lower the paper surface by a certain amount. When the load increases and the elevator repeatedly descends until it reaches a specified position on its stroke, it is detected that the deck is fully loaded, and further access to paper is prohibited.

This full load detection is performed by a load detection microswitch 24 disposed along the lift guide. Figure 1 is A
This shows that the side deck is fully loaded and the B side deck is ready for loading and is currently being loaded.

FIG. 2 shows an external view of the loading device 5 of this embodiment connected to the printer 1. As shown in FIG.

107a is a parking motor corresponding to the elevator motor 28a in FIG. 1, 108 (hereinafter scifixes a and b are omitted) is a driver for A and Takashi motor, 109 is a fully loaded detection brake switch corresponding to 24 in FIG. 1, and 110 is a 111 is a microswitch for detecting whether or not the Jj'f Ii plate 17 is pulled out; 112 is its buffer; 113 is a full load indicator corresponding to 35 in FIG.
14 is the error display whose buffer 115 is listed at 36 in the t52 diagram, and 116 is its cross and f.

Block 102b also has exactly the same configuration as block 102a.

These drivers and buffers are in the interface section P.
The IA 117 is connected to the PIA 117, and the PIA 117 is connected via a path to a central processing unit (22) MPU consisting of 118 processing units and storage units. This MPU 118 is also connected to another interface unit PIA 119 via a path, and the PIA 119 is connected to a printer 120 corresponding to the printer 1 in FIG. The PIA 121 sends and receives data under the control of the printer control unit 122.

Next, display control of the full load indicator 35 of the loading device having the above configuration will be explained with reference to the flowchart of FIG.

In step 201, it is checked whether there is a deck full of M loading sections on both decks A and B for five rounds, and if there is no 'JF4 loading section', no processing is performed and the process ends. 1aR Tetsuki is good
If so, the process advances to step 203, where it is determined whether deck A is fully loaded.

If the A-side deck is not fully loaded, the other B-side deck is fully loaded, so the process goes to step 204, where the fully loaded indicator 35b of the B-side deck is turned on, and then, at step 205, the paper container 12b of the B-side deck is turned on. The stacking plate detection microswitch 111b shown in FIG.
If the withdrawal is not completed, proceed to step 2.
01 and lights up the full load indicator 35b until it is pulled out.

If the deck on the A side is fully loaded in step 203, the process proceeds to step 206, and it is checked whether the fully loaded indicator 35b of the deck on the B side is lit. If it is lit, the process proceeds to step 205, and the loading is started from the deck on the B side. Wait for the paper removal process to start.

When the JflIN plate 17b of the B-side deck is pulled out in step 205, the process proceeds to step 210, where the full load indicator 35b of the B-side deck is turned off, and step 201 is performed again.
Return to

Also, in step 206, the full load indicator 35b of the B side deck is
If it is not lit, that is, if only the A-side deck is fully loaded, the process proceeds to step 207, where the full-load indicator 35a of the A-side deck is lit, and in step 208, the loading plate 17a of the B-side deck is pulled out. to monitor. When it is pulled out, the process advances to step 209, where the A side full load indicator 35a is turned off and the process returns to step 201.

In the flowchart shown in FIG. 4, even if the letters ``A side PA'' and ``B side'' are changed, the lighting status of each display is yh.

It is clear that nothing has changed.

Further, in this flowchart, the explanation has been limited to a two-stage loading section, but the gist of Kisaraaki does not change even in a loading device having two or more stages of loading sections.

In addition, in a loading device that has multiple loading sections, if multiple decks are already fully loaded and the operator of the tree loading device accidentally pulls out a deck that is not the one that should be taken out first, the deck may be ;x (By decrementing the display of the highest priority deck to show the tip that has been pulled out in a hurry and calling attention to it, necessary processing can be carried out quickly.

The control method in this case will be explained using FIGS. 5 to 7.

FIG. 5 schematically shows a loading device having N deck sections similar to those shown in FIG. The materials are transported along the designated transport path and loaded onto each deck. Each deck section has a display section and an operation section shown in FIG.

Hereinafter, each deck portion will be referred to as deck 1 to deck N, corresponding to (1) to (N) shown in FIG. 5.

FIG. 6 is a deck management table in the RAM (random access memory) in the MPU 118 shown in FIG.
``''a+bl~b+C-1~C indicate the addresses of the table, and each deck number is given a suffix for simplicity.

In FIG. 6(A), when each decker is fully loaded, for example, when deck 2 and deck N are loaded in the order of 1F4, "1" is written to address a2 and "2" is written to address a. This area is reset (written as "o") when one job is completed, the stacking plate of the deck is pulled out, and all stacked papers are taken out.

Figure 6 (E) is a deck full table in which a full flag is set at the address corresponding to the deck number when each deck becomes fully loaded. will be reset.

FIG. 6(C) is a plate insertion table showing whether or not the loading plate of each deck is pulled out; if the loading plate is inserted, the insertion flag is set;
If it is pulled out, it is a reset.

Next, the control of full load display when there are many decks will be explained with reference to the flowchart shown in FIG.

First, in step 301, in order to check the full state, unloaded state, and 1116th priority position for all N decks, n=1 is set in order to check sequentially starting from deck 1.

Then, in step 302, to check whether the deck n is full or not, the bn of the deck full table is set to 3.
I can go around. If bn is reset, the deck is not full, so in step 312, it is checked whether n-, and n=, that is, whether the fullness check for all decks has been completed.
If all have been completed, return to step 301 and repeat n.
= 1, perform mR check sequentially from deck 1,
If not all are completed, n is +1 in step 313.
Then, the process returns to step 302 to perform a full load check on the next deck section.

If bn is set in step 302, that is, if the deck is fully loaded, the process proceeds to step 303, where cn on the plate insertion table is checked to check whether the loaded plate of the deck has been pulled out. If it has been pulled out, cn is reset) and the process proceeds to step 308, where the ann of the relevant deck section of the priority table is
It is checked whether an is the minimum value of the priority table, and 1j is the deck with the highest priority. In the case of the most ffF destination deck, the process advances to step 309, and the deck frli
Turn off the full load indicator and reset an. The process then proceeds to step 312.

In step 308, if the deck γζ1;
If you have pulled out another fully loaded deck, please proceed to step 3.
Proceed to step 10, invalidate an in the priority table, and
Then, in step 311, the full-load indicator of the deck section having the lowest value in the priority table and to be taken out with the highest priority is flashed, and then the process proceeds to step 312. . ~ In step 303, if cn of the play I/insertion table has been set to Sera I and the plate of the relevant deck has not been pulled out, the process proceeds to step 304, and in the priority table, the an of the relevant deck is selected as the minimum or maximum. It is checked whether it is a priority deck, and if it is not the highest priority deck, the process proceeds to step 312 and the full load indicator of the deck is not turned on.

If it is the deck with the highest priority, the process proceeds to step 305, and it is checked whether the fully loaded indicator is blinking. If it is not blinking, the fully loaded indicator of the deck is turned on in step 306, and the process proceeds to step 312, and if it is blinking, the process proceeds to step 312. If so, the process directly advances to step 312.

The present invention is not limited only to the control method explained in FIGS. 5 to 7, and if it is pulled out by mistake, an error indicator or buzzer other than the blinking full load indicator may be used. It's okay.

Further, as a method for determining whether the deck has been pulled out, a microswitch may be used, or a sensor for detecting the presence or absence of stacked paper in the deck may be used in combination. In addition to optical sensors and mechanical microswitches, the gist of the present invention is to have a function that counts the number of sheets actually loaded and generates a signal indicating that the sheet is fully loaded when a specified value is reached. It is not something that can be changed, but can be set arbitrarily by the operator.

Furthermore, it goes without saying that the aforementioned microswitch and prescribed number counter may be used together.

In addition, this display control method is not limited by the loading mode. For example, in Fig. 5, in addition to the so-called stack mode in which the nth deck is sequentially shifted to the n+1st deck when it is fully loaded, there is also a mode called parts mode, in which each In a mode in which the same page is loaded on each deck, it receives a mode signal from the printer, executes the flowchart shown in Figure 7 in the stack mode, and loads all the fully loaded decks in the stack mode. It is also possible to turn on the 1a flit indicator.

In addition, in this embodiment, each deck had one fully loaded indicator, but there is a well-known 7
It may have a segment indicator etc., and the priority 111
Sending the first place to a printer and displaying it on the printer does not change the gist of the present invention.

Moreover, it goes without saying that instead of the display device, lighting inside the loading section provided in each deck may be controlled according to the flowchart shown in FIG.

Effects As explained above, according to the present invention, in a loading device equipped with a plurality of paper sheet loading means, it is possible to clearly display the order in which the stacked sheets are taken out using only the display of each stacking child. , the operator of the device can also take out the stacked paper sheets without fail.
