Abstract

PURPOSE:To provide a required automatic control even when any troubles occur in feeding a tape, by controlling the operativeness and inoperativeness of a motor for supplying a tape on the basis of a tape sensor and a sheet sensor. CONSTITUTION:When the absence of a tape is detected by a tape sensor 31 continuously a certain set time or more after a mark commanding signal input is supplied externally, a motor 11 for a tape supply mechanism is controlled to be set to the inoperative condition while a signal output representing the non- insertion of the tape is supplied. When the absence of the sheet is detected by a sheet sensor 32 in the supply of the mark commanding signal input, the motor is operated to feed the tape, whereas the feed of the tape is held when the presence of the sheet is detected.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for reducing the number of sheets (for example, paper) cut into predetermined lengths and stacking them, such as the number of sheets or defective sheets.
A mark tape cutting/feeding device for sending and dropping markings as information markers, a tape feeding mechanism that feeds the tape into a tape tube driven by the IfIK1 motor, and a tape cutting mechanism that cuts the fed tape by passing through it. Regarding preparation 9 mark chi 1 cutting feed p included W.

For example, a multi-sheet simultaneous cutting IIO paper cutting machine, in other words, simultaneously feeds out multiple rolls of paper, polymerizes them, cuts them lengthwise in the longitudinal direction at the same time, and then simultaneously cuts multiple rolls of paper into multiple rows that run simultaneously. In a paper cutting machine that simultaneously cuts paper into long lengths and stacks the paper in multiple rows, the paper tubes are simultaneously transferred to the stacking section by the same belt conveyor and stacked in each row. The tape is placed in a corresponding manner, and for each row of paper sheets that are dropped and stacked from the end of the belt conveyor, a fixed number of tapes are fed midway within the falling range. There is.

The feeding is performed based on the mark command signal of the sheet number counter provided in the paper cutting machine. This is done to ensure that the tape is inserted into the paper, but the falling and stacking is done closely and consecutively, and the polymerization state of each set of cut and polymerized paper is separated, so in conventional ID, There was a drawback that the tape that was being fed 9 collided with the continuously falling paper m and was not inserted between the paper sheets, but instead was inserted at the wrong number of sheets η1 position.

Shigeyoshi, this type of paper cutting machine has paper sheets stacked in the loading area [transported to other places by forklift, etc.]
Mark tape cutting feeder 1. @If placed in front of the soft part or on the left and right sides, it will interfere with the conveyance work, so
It is placed behind the loading section and below the belt conveyor so as not to get in the way.

However, in such a situation, it is difficult for a work supervisor to constantly monitor the situation including the tape feeding and the IR in places where it is difficult for the work supervisor to monitor. If the tape is installed in such a position, the cutting part of the tape cutting mechanism must be used to feed the tape by using the space 1gK% below the end of the belt conveyor. The drive unit and tape feeding mechanism of the tape cutting mechanism are placed in the above-mentioned free space, and the drive unit and tape feeding mechanism of the mechanism are installed at separate required positions, and the drive unit and cutting unit of the tape cutting mechanism are linked by a link machine. , the tape is fed by a tape feeding mechanism (the tape is guided by a cutting groove in the tape guide gutter).

However, in this way, for the aJ# part of the tape cutting mechanism, its drive unit and tape feeding mechanism! If they are placed far apart, there will be many problems with the Q1, feed, and P operations.In the evening, even though the tape feeder was operating horizontally, the tape was cut at the cutting part!
However, in the present invention, even when a large number of sheets fall continuously (from a belt conveyor), the tape cannot be fed until it passes the IFK.
A predetermined distance between sheets I to avoid collision tg with a falling sheet
In addition to accurately inserting the tape, it also detects whether or not the tape has passed through the tape cutting machine's tube, so that the necessary automatic control can be performed in the event that trouble occurs in feeding the tape.

In other words, the present invention consists of a tape sensor that detects nine tapes passing through the tape cutting machine's stack tube, a sheet sensor that detects the stacked sheet tubes, and a sensor that detects the presence or absence of tape and detects the presence or absence of sheets by these two sensors. The present invention is characterized by comprising a control circuit capable of controlling the operation and opening of the motor of the tape feeding mechanism depending on the timing.

Further, as described above, the present invention provides automatic control (1) to perform tape feeding operation 1 to avoid collision with a sheet, and to perform automatic control (1) to perform the tape feeding operation when a trouble occurs. In other words, the above-mentioned operations are appropriately synchronized with the operations of the cutting machine so that they can be performed accurately.

That is, if the detection of no tape by the tape sensor continues for more than a certain set time when the external mark command signal is input, the tape feeding mechanism O
motor! In addition to controlling the system to be inactive, if the tape is not inserted, the detection of the absence of the P sheet is performed.
IK4, the above motor is activated to carry out the tape feed pipe, but when the presence of sheets is detected, the tape feed is suspended and the pipe becomes hot. 0 Below, the illustrated embodiment of the present invention 8At will be described in detail.

First, let's talk about the mechanical configuration of this mark tape cutting/feeding device. 2I! As shown in il, the reel Bt is installed on the main body ho @ @ with the reel mounting rod 1, and a long tape guide gutter Ct is installed on the front side of the KII, and the cutting part of the Q1 cutting mechanism is installed at the tip of this gutter C. @ Reel B has a flange 3 on the periphery of the disc 20, and a roll tape support shaft 4 is inserted through the center of the disc 2, so that the flange 30 notches @ S, O both ends are 9% When the tape guide rollers 5, 5 are supported pivotally, the external gA of the disk 20 is %.
A limit switch 6 for detecting roll tape is attached at a predetermined position t.

The switch actuating lever 7 of the limit switch 6 has a spring force, and as shown in FIG. When the tape T supported in the winding WjA state on the tape support shaft 4 is fed out and the winding diameter becomes small enough to exceed the slit 81, the lever 7 is actuated and the limit switch 6 is turned on. It is.

The main body of the round B is constructed such that the disc 2 is inclined with respect to the vertical 1 [@ and its inner surface is slightly upward. Therefore, the inner side of the disc 20 is pressed against the inner surface of the disk 20, and in order to prevent it from rotating unnecessarily, the sn out is performed with an appropriate tension. The reel B is adjusted to have an angle of 8 with respect to the main body, and by adjusting the angle, the tension is increased by adjusting the tension tIlij.

The tape T supported by the reel BK is guided to the tape guide row 25.5, and then passes between the nine pinch rollers 9#lO, which are pivotally supported outside the main body AC), and is placed inside the main body A by the person 9 and inside. The tape feeding mechanism installed in
B8 is fed into the tape guide trough C while passing.

That is, inside the main body A, as shown in Figure tIIi2, there is a synchronous motor 11. Feed roller 12, which is integral with its rotating shaft. A pinch roller 13 is provided with a spring force so as to come into pressure contact with the feed roller 12, and the tape T entering the main body l is moved to the feed roller 12 by the drive of the motor 11.
As the tape 2 rotates, it passes between it and the pinch roller 13 and is fed into the tape guide trough C.

ζO@C forms a long groove 151 on the entire length of the upper surface of the elongated plate 14 as shown in detail in No. 5H, and then attaches it to the transparent long cover plate 1.
6 to cover it and remove it 1 [U-shaped clamping piece 1 with tension]
The chi 1T runs along the groove 15 and is sent outward from the cut part at the tip of -C, and the structure of the cut part is as follows. In other words, the cutter frame 180 is attached to the tip of the gutter C.
Although not shown, a rotary cutter ttg1 is rotatably mounted on a shaft and a fixed cutter t1m is mounted on the shaft. For example, a rotary ivy is made by cutting out the middle part of a horizontally long cylindrical body, and cutting out one side edge of the notched blind part [, shaft 11
The cutting blade is inclined at a required angle fte with respect to 169, and the fixed cutter is a cutting blade that meets the same side edge of a rectangular plate.

These granite cutters normally have a gap between their cutting blades that is sufficient to allow the tape TYt to pass through, but when the rotary cutter rotates in a predetermined direction, the cutting blade connects with the cutting blade of the fixed cutter. intersect, thereby tape Tl
It has become self-sustaining through amputation.

The rotation of the rotary cutter in the predetermined direction is performed by the action of an electromagnet 19 disposed within the main body A;
tue rotation is performed by a spring force.

That is, the rotary cutter is directly connected to a crank 20 on the outside of the cutter frame 18, and this crank 20 is connected to a disc crank 2 supported by the gutter CK via a link rod 21.
2, and this crank 22 has a coil d
A bushier rod 24 equipped with a screw 23tl is connected.

When the rear end of this rod 24 enters into the butterfly body A, the electromagnet 19 is activated and the lever 26 connected to the plunger 25 pushes the lever 24 forward against the spring 23. , the disk crank 22 rotates, and this rotation causes the crank 20 to rotate and the rotary cutter to rotate in the above-mentioned direction and break. ◎When the electromagnet 19 is cut, the rod 24
is moved backward by the action of the spring 23, and the rotary cutter makes one return rotation.

Both rods 24 are connected to the disc crank 22 by joint pins 27, 27, as shown in detail in FIG. - These joint pins 27, 27 are prevented from being pulled out by a so-called split pin with a retaining ring 28.
It is carried out by 28.

In other words, the locking ring 2B is made by bending a single metal wire into a tlI shape and overlapping both ends of the wire.
Each ring 28 has a horizontal hole 2 in each joint pin 27 from its end.
71 and is supported by sliding and turning.

Therefore, each joint pin 27 is removed from the disc crank 2-2 by the ring 28! The ring 28 is also blocked by the transverse hole 27 . The point of contact with the horizontal hole 271 moves in the circumferential direction as the disk crank 220 reciprocates due to sliding rotation.
71 and always only in a certain part of the joint bottle 2.
The durability of the ring 28C) is much better than that of the ring 28C).

The above crank 20 and link rod 21! 29% of the connected joint bottles are similarly prevented from coming off by a retaining ring 30.

As described above, the tape i passing through the barrier between the cutting blade of the rotary cutter and the cutting blade of the fixed cutter is immediately sent outward from the barrier opening of the cutter housing 18, and it passes through this opening. Whether it passes or not! Is the tape attached to the bottom 11 of the cutter housing 18 for detection? -31 is attached to the upper side of the cutter housing 18.
Stackable Sea)? A round sheet sensor 32 for detection is attached.

In this embodiment, these sensors 31 and 32 are both reflective type rechargeable sensors equipped with a light emitting element and a light receiving element for receiving the reflected light.

Therefore, in order to apply the mark tape cutting/feeding device 9 to the above-mentioned paper cutting machine, the cutting device sD should be positioned below the final part of the belt conveyor E as shown in FIG. The sheet sensor 32 detects the sheet (paper leaf) 8t1 at a predetermined position in the middle of its fall, and the sheet (paper leaf) 8t1 falls down the belt conveyor E and is stacked on a so-called layboy (not shown). If you don't have it, make sure to send 9 tapes to yourself.
Therefore, such tape feeding operation is performed by the electric circuit shown in FIG. It will be done.

Therefore, I will explain about this next.

When a mark command signal is input between input terminals 34 and 35 from an external sheet number counter provided in the paper cutting machine,
Relay 36 momentarily energizes its a contact 36. is closed and relays 37 and 38 are energized.

Relay 38 maintains itself by closing its 111 points 38□.

Relay 37 is number 1! & point 371 is closed, b contact 37
When R is opened, the contact 37. Close. As a result, the timer 40 for setting the tape no-detection time
Sera) 1 will be.

The timer 40ri is reset by the transistor 41 when the tape sensor 31 detects a detection tube with tape, but if it is set without being reset and operates for the required time, the relay 42 is energized.

Therefore, timer 41? ! It is reset immediately after being set, and the relay 42 is not connected.However,
If the state in which the tape T does not pass through the cutting portion Dt continues for a certain period of time set by the timer 40 when the mark command signal is input, the relay 42 is energized and the b contact 42.
is opened, the relay 38 is deenergized, and the IA contact 42 is closed, so that a signal indicating that the mark is not inserted is output to an external circuit, for example, the number of sheets mentioned above.

When the head relay 38 is energized based on the mark command signal as described above, the a contact 38. is closed, which normally activates the transistor 43 to activate the thyristor 44, which activates the tape length power setting tie-f45 and the unijunction transistor 46, thereby causing the 11 friend 2 earphone 47 to operate. When activated, the camera 11 is driven. This driving continues for the time set by the timer 45 to energize the relay 48 until Ob*A4g is opened and the relay 38 is deenergized.

Therefore, each time the mark command signal is input, the tape T is fed by a fixed length corresponding to the set time of the timer 45. When the tape T is fed in this way, for example, A cut command signal is input between the output sheet number counter and the input terminals 35 and 49, the electromagnet 19 is operated, and the tape T is cut as described above. However, when the sheet sensor 32 detects the sheet S' is detected (detection of 46), the above-mentioned relay 3
Even if the transistor 8 is energized and the Al1 point 381 is closed, the transistor 43 is not activated, so the series of operations described above are not performed, and the tape T is not fed because the hair holder 11 is not driven.

When the detection of the sheet sensor 32 changes from the presence of a sheet to the absence of a sheet, the transistor 43 is activated at that time, and the feeding operation of the tape T is performed after the sheet 8 is out of the detection range of the sheet sensor 32.

However, when the mark command signal was manually input from the outside,
If the sheet is not within the detection range of the sheet sensor 32,
The tape T is immediately fed in and cut to a predetermined length, but if there is a sheet 8, feeding of the tape TO is suspended and the tape is cut into a predetermined length.
The tape T is fed and cut after sheet 8 runs out, and the tape T that is fed collides with the falling sheet B and inserts sheet 8111K, which is rare. When the limit switch 6 is turned on at the front feeder B, a signal indicating that the wound tape T is running out is output. 50 is a rectifier, 51 is a constant voltage element, and 52 is a Norst-Tuns.

As described in detail above, the present invention is equipped with a sheet sensor that detects stacked sheets, and the feeding and stopping of the tape is controlled based on the detection of the presence or absence of the sheet, so that the tape t1 falls. It avoids the sound of collision with the sheet and accurately inserts the sheet at the factory-defined sheet spacing. Also, the tape sensor detects whether or not the tape has passed through the tape cutting mechanism, so there is no trouble in feeding the tape. When the occurrence occurs, the automatic control 41t can be carried out ◎ Furthermore, as stated in claim 2, I! In the invention, if the tape sensor detects the absence of tape for a predetermined period of time or more after the mark command signal is input from the outside, the customer controls the motor of the chive feeding mechanism to be inactive. At the same time, a signal indicating that the tape is not inserted into the tube is output, and when the mark command signal is input, the sheet sensor detects the absence of a sheet. is activated to feed the tape, but if the presence of a sheet is detected, the tape feed is suspended.
As mentioned above, there was a problem in the tape O feeding operation to avoid collision with the sheet, and in the seventh feeding P.
The automatic side W to be performed is, for example, a paper cutting machine O operation and Krml as appropriate.
This is number 4, which is determined by doing it accurately.
