A tape holding claw 17a that rotates and forms a loop on the tape 15, 18a and 18b are a pair of upper and lower guide bodies that guide the conveyance of the tape 15, and 19 is a feeding means and a tightening means for feeding the tape 15. Drive roller that doubles as 2
Reference numeral 0 is a driven roller facing the driving roller 19, 21 is a rotatable tape adhesive member having a heater 22 at its tip, 23 is a tension roller for pulling the tape 15, and the upper guide body 18a And tape adhesive member 2
Cuts 24a and 24b of cutting means for cutting the tape are provided at the tip of the tape 1 with an appropriate gap.

In the figure, the tape 15 passes through a tension roller 23, and then a driving roller 19 and a driven roller 20.
It passes through the space and is guided between the guide bodies 18a and 18b. The operation is performed in the following order.

First, the tape 15 is rotated by the drive roller 19 in the clockwise direction to clamp the tape 1 at the right end of the tape holding claw 17.
7a, and the tip of the tape 15 is inserted into the clamp portion 17a.

Next, the tape holding claw 17 and the guide body 18a,
18b rotates counterclockwise as shown by the solid line in FIG. At this time, the driving rollers 19 rotate at the same time to prevent the tape 15 from being fed out and the tip of the tape 15 from coming off from the clamp portion 17a. The tape holding claw 17 continues to rotate and rotates 360 ° to the position shown in FIG. 1 and then stops.

After that, the guide members 18a and 18b are set in FIG.
Returning to the position, the tape 15 is sandwiched between the tape 15 and one end of the tape holding claw 17 as shown in FIG. The drive roller 19 continues to rotate, and the tape 15 is at the position (length) indicated by the alternate long and short dash line.
Tape 15 until it reaches. In this state, the copied recording paper is ejected from the copy processing section A into the loop of the tape 15. After the required number of copies have been discharged, the copy processing unit A gives a copy end signal to the recording paper band bundle processing unit B.

After that, as shown in FIG.
Rotates counterclockwise to tighten the recording paper P. In this state, the tape adhesive member 21 rotates clockwise around the fulcrum to bring the heater 22 into contact with the tape 15 to melt the adhesive of the tape 15 and paste the tapes 15 to each other.

The upper left portion of the tip of the tape adhesive member 21 and the guide member 18a have appropriate gaps and cutters 24a, 24b for cutting the tape, and the guide members 18a, 18b.
The tape 15 is cut by the clockwise rotation of the tape.

Further, the tape holding claw 17 is retracted in the rearward direction of the bundle of recording paper P, and the tape adhesive member 21 is retracted to the original position to complete a series of banding work. Upon detecting that the bundle of recording paper P has been removed, the tape holding claw 17 returns to the original position in FIG. After that, the above operation is repeated.

FIG. 6 is an explanatory view of a state in which the recording paper is fastened with a tape. When the recording paper P has a weak stiffness (low rigidity) or has a large size, the band bundle is in the longitudinal direction or the number of sheets. When the tape 15 has a small amount, the tape 15 does not bend along the recording paper P when the rigidity of the tape 15 is high, and the recording paper P bundle is buckled and deformed.

Therefore, in the present invention, the tape pull-in control is performed by detecting the type (size, rigidity) of the recording paper P or the type (rigidity) of the tape as follows.

Next, a mechanism for detecting the type of the recording paper P will be described.

FIG. 7 is a perspective view of the paper feeding unit 9 shown in FIG. 2, 41 and 41 are side fences, 42 is an end fence, and the recording paper P is fed in the direction of arrow A.

FIG. 8 is a front view of the paper feeding unit 9, and 43 (4
3a, 43b, 43c) are paper sensors that detect the orientation and size of the recording paper P by detecting the positions of the side fence 41 and the end fence 42.

As described above, the degree of deformation of the recording paper P due to the tape 15 varies depending on the rigidity and the number of the recording paper P. Therefore, the characteristics and the number of the recording paper P are detected by the paper sensor 43 and the thickness detection which will be described later. As described above, the pull-in control of the tape 15 is performed by detecting the signal from the sensor or by inputting the information such as the tear strength (shear resistance) from the operation unit.

Incidentally, the rigidity of the recording paper P is measured as shown in FIG. 9, for example.

That is, the hip strength is measured from the bending range (1, 2, 3; indicated by a) in which the tip of the recording paper P is projected from the base 51 and returned to the original position. Determine the stiffness.

Since this rigidity has a relative correlation with the thickness of the recording paper P, the mechanism shown in FIG. 10 is used to measure the thickness of the recording paper P.

In the figure, reference numeral 61 is a drive side conveyance roller, and 6
2 is a driven roller which is displaced up and down according to the thickness of the recording paper P, 63 is an arm which rotates in conjunction with the displacement of the driven roller 62, and 64 is a position of the recording paper P which is detected by detecting the position of the arm 63. A thickness detection sensor for detecting thickness.

FIG. 11 is a vertical cross-sectional view of a set cartridge containing a roll-shaped tape (tape roll).
FIG. 3 is a perspective view of the cartridge.

The cartridge 70 has a tape storage portion 72 for storing the tape roll 71 and a tape feeding portion 73 located at a portion communicating with the tape storage portion 72 to the outside.
The center of winding of the tape roll 71 is rotatably held by a tape roll holding shaft 74 formed integrally with the tape storage portion 72.

The tape feeding section 73 has a feeding port 75.
And a roller pair including a feeding roller (driving roller) 76 and a pinch roller 77. Since the adhesive layer of the tape 15 is generally inside the tape roll 71, the pay-out roller 76 is constructed so as to contact the back side thereof. On the other hand, the feeding roller 76 may be on the adhesive layer side, and a leaf spring or the like may be brought into contact with the back surface to omit the pinch roller 57, thereby reducing the cost.

As shown in FIG. 12, the drive shaft 78 of the feeding roller 76 is inserted into the outer surface of the cartridge 70, and the drive shaft gear 79 at the outer peripheral portion is fixed to the tape roll holding shaft 74. It meshes with the tape roll rotary gear 80. An intermediate gear may be provided between both gears. Further, these gears may be installed inside the cartridge 70 in order to reduce irregularities on the outside of the cartridge 70 and facilitate handling. Further, the drive transmission may be pressed against the outer circumference of the tape to prevent the amount of feeding and the amount of drawing due to the change of the tape winding diameter.

In FIG. 12, since the central hole of the tape roll 71 and the tape roll holding shaft 74 are loosely fitted (the tape pull-in amount is increased by the rotation of the tape roll 71), the fitting is slid. This prevents the difference in the tape pull-in amount.

At the time of feeding the tape, a one-way clutch is provided on the tape roll holding shaft 74 or the drive shaft 78 to prevent the tape roll 71 from rotating in the feeding direction, so that the tape 15 receives the pulling force at the time of sliding. Give and prevent tape slack.

On a part of the outer surface of the cartridge 70, a characteristic information transmission medium 81 showing the characteristics of the tape 15 by a bar code or the like is provided, for example, a bar code reading device or the like provided on the banding machine. The tape type is recognized by the tape type determination sensor, and various band bundle conditions are set.

The emptied cartridge 70 is reused. Alternatively, when the internal tape roll 71 is replaced, the above bar code may be replaced, and as shown in FIG. 13, for example, the convex portion configuring the characteristic information transmission medium 81 is shifted and provided on the banding machine. The position may be read by a micro switch or the like.

FIG. 14 is a characteristic diagram showing the relationship between the tape length after tightening (which originally matches the circumferential length of the bundle of recording paper P) and the buckling height.

As described above, when various conditions such as the rigidity of the recording paper P, the size, the number of sheets, the rigidity of the tape 15 and the orientation of the band bundle are met at a certain level, as shown in FIG. The buckling height of the recording paper P exhibits a certain value even when an ideal amount of tightening is obtained in which the circumferential length of the bundle of recording paper P in the tightening direction of 15 and the loop length of the tape 15 after tightening are the same. .

Therefore, while the buckling height of the recording paper is being measured while the tape is being drawn in for tightening the recording paper P, the drawing is completed when the buckling height reaches a predetermined value, so that good tightening can be achieved. it can.

The buckling height may be measured by the reflection type optical sensor array 90 as shown in FIG. 15 (the lowest sensor of the presence of the recording paper is the detection point). ,
A light-shielding type optical sensor array 101 having a detection arm 100 as shown in FIG. 16 may be used, or an appropriate one such as a magnetic sensor array using the detection arm as a magnetic body may be used.

In the case of the mechanism shown in FIG. 16, by making the contact point of the detection arm 100 with the recording paper P close to the tape 15,
It can be detected at a fixed position regardless of the size (in the case of FIG. 15, the sensor needs to be moved depending on the size and the orientation of the recording paper P). In order to retract the detection arm 100 during stacking of the recording paper, for example, as shown in FIG. 16, the detection arm 100 is retracted by the weight of the arm 100 or the like, and the measurement position is determined by the solenoid 102 or the like (via the weak spring 103) only during measurement. You can move it to.

By the way, as shown in FIG. 14b, when the above-mentioned conditions change, the buckling height becomes different even if the pull-in amount is the same. In these cases as well, in order to obtain a good bundle, obtain an information signal (tightening control signal) of the above conditions,
Change the buckling height to complete the pull-in.

To change the detection height, the sensor array 9
A sensor at different positions may be operated instead of the sensor corresponding to the detection point under a certain condition of 0 and 101, or a single sensor can be displaced in a plurality of positions and the sensor can be moved depending on the condition. You can do it.

In the finished state of the bundle of bundles, the user may prefer a little looseness or a tight fit. It is desirable that the operator not only perform the above-described automatic adjustment but also make fine adjustment.

There are cases where an error occurs in the automatic detection control (such as when the buckling height changes due to factors other than the above detection; recording paper curl, etc.), and it is necessary for the operator to adjust with high accuracy. May occur. Better bundle performance can be obtained by inserting necessary values from an operation unit of the recording apparatus or an input device provided in the bundle machine, which will be described later, and determining the buckling height detection position based on this.

By the way, the horizontally stacked recording paper P
When the bundle is tightened with the tape 15, the buckling does not have a desired shape as shown in FIG. 18, for example, and the measured buckling height may be greatly deviated.

As a countermeasure against this, as shown in FIG. 19, the height difference between the tape holding claw 17 and the tape guide 16 and the tray surface at the center of the recording paper stack is made a little larger, and the recording paper stack is projected upward. The recording paper P bundle may be given a habit so that Also, in order to make the recording paper P curled in the opposite direction into a normal buckling shape, the side edge pressing member 31 may be used together as shown in the drawing.

The side end pressing members 31 provided on both sides are
It is driven by a motor 32 via a wire 33, a clamp 34, and a guide rod 35, and moves in a direction in which they expand and a direction in which they narrow.

The band bundle processing section B is provided with a dedicated control device 110 for transmitting and receiving signals to and from various sensors and loads such as motors, and a heater power supply 112 for applying electric power to the heater 111. You are in control. Further, the control device 110 controls the motor 114 that rotates the drive roller 19 via the motor drive circuit 113.
