Detailed Description of the Invention 3. Detailed Description of the Invention [Object of the Invention 1 (Field of Industrial Application) The present invention relates to a filter paper band feeding device used for banknote bundling and the like.

(Prior art) In a filter paper band feeding device used in a banknote counting and bundling device, when the feed button is pressed after changing the paper band, the +-R pair for conveyance automatically rotates to feed the fl band. It can be sent to the processing position.

Enabling this automatic setting mode requires a pair of rollers and a pair of guide plates arranged in several stages near the feeding end of the paper strip. The lick end must be guided to a nearby roller pair position, making the work complicated.

(Light (problem that the moon is trying to solve)) In the processing mode after setting, the paper strip is moved from the processing holding hoe position to the [addition] [position], and the bundle is wound, tightened, fused, and end-cut in the following order. Processed.

Therefore, when tightening, the rollers rotate in reverse, so it is necessary to prevent page jams by creating a large space between the feeding end of the paper strip and the nearest roller, and storing and covering the reversely fed paper strip within this space. There is.

In other words, in the machining mode, the row r
1 is required.

Of course, even if we ignore the time it takes for replacement workers to hit, taking up this kind of space makes it difficult to make the housing that houses the internal structure into a doll. ], which raises the issue of undesirable installation space.

The purpose of this invention is to satisfy the above-mentioned conflicting conditions, to facilitate the setting work, and to secure a space sufficient to accommodate reverse-fed paper strips even if the volume of the housing is small. shall be.

By closing as shown in the figure, the cushion pad 60 tilts the knock 28 and unlocks the control f1 arm 17.

As a result, the operating arm 17 is rotated again in the time t1 direction by the biasing force of the spring 2o, and is held in the vertical position shown in FIG.

Further, an arbitrary arm 31 is connected to the Ii'l recording flF arm 17.

The tension arm 31 is located on the side surface of the paper strip 3 and is supported so as to be able to rotate about a central shaft 32 coaxial with the solid shaft portion of the reel 22, and one end is supported by a spring 33 suspended on the fixed side. It is normally energized to turn at 1 tV ++ in the '7 meter direction.

A roller 34 is provided at one end of the transfer arm 31, and the paper sheet 1''I3 is delivered to the conveyance guide section through this roller 34.

In addition, the other (one side) abuts against a bearing 35 provided on the operation arm 17, so that the turning operation is performed.
At the same time, it is in contact with the brake 36 located on the side of the paper 3 and attached to the fixed fl1q (J+).

As shown in Fig. 3 (a) and (b), the leaf spring 37 attached to the r,

, (2)), this judgment is based on the signals from the above-mentioned leet switch 52 and the tip detection section 106.

YES, if it is supplied, please add it (
Step (3)), and it is determined whether or not there is a jam in the machining t-gutter σ (step (4)), and if there is no jam ring, the above steps (1) to (4) are repeated. . Note that the machining mode (J will be described later).

If No is determined in steps (1), (2), and (4), an alarm output (alarm lamp, alarm alarm, etc.) is generated and the device is stopped at the same time (steps (5) and (6)). .

After that, manual operation is performed by the staff (step (
7)).

The manual operation procedure is as follows.

(2) When the housing 1 is pulled out and the operating arm 17 is pushed forward with the internal structure exposed, the reel 22 can be freely taken out from the case 2.

■If a jam occurs, you can remove it by twisting the reel and pulling it out.

When replacing the 0 paper 71''13, set the reel 22 with a new paper strip 3 wound on the case 2, and turn it gently in the forward direction. Passing through the roller 34 of the tensicon arm 31, the first roller pair 6

Next, the machining mode will be explained using the flowchart shown in FIG.

First, upon receiving a banknote detection signal (not shown), the motor 4 operates i! ″
! It rotates forward at high speed, feeds out the paper band 3 to the processing position [II], and winds the bundle of bills (step (1=l)).

Upon receiving the winding end signal, the motor 4 rotates in reverse at high speed, and the paper strip 3
(step (16)). When the tightening tension becomes constant, the motor 4 stops and moves to step (17), (18)"), machining special machine position [II
] Heater 100 h<Takeshinshi, Volume! Heat melt one end and then retract (step (19)). Next, the cutter 101 advances to cut the edge of the paper, and retreats (step (20)), thereby completing the processing process.

Then, when the motor is reversed in step (1G), the paper strip 3 is sent back to the storage space A side, and the tension arm 31 is moved to the maximum limit. By rotating in the needle direction, a brake 36 acts on the reel 22 to stop feeding out the paper strip due to inertia during high-speed rotation. Therefore, the volume of the space can be determined by shifting the design to account for the filter paper strip 3 that is fed back from the processing position [I].

(Effects of the Invention) As explained by way of example to L. Sue, according to the present invention, by locating the operating arm in close contact with the rollers when setting and loading a paper strip, the roller pair closest to the feeding end is positioned. paper strip can be easily and automatically set. When the housing is then closed, one of the rollers is spaced apart, creating a space sufficient to accommodate the reversing paper strip.

Therefore, according to the present invention, the automatic retrieval of the paper strip is simple, and even though the housing volume is small, it is possible to prevent vapor jams due to reverse feeding.
