DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a paper bundle banding device for bundling a predetermined number of paper sheets with a band-wrapping tape, and a paper for carrying the paper bundle to a winding position by the band-wrapping tape. The present invention relates to a bundle guide device.

[Prior Art] A band-wrapping tape is used for bundling paper sheets such as banknotes every predetermined number of sheets, but a paper-bundle band-wrapping device is used for winding the band-wrapping tape around a predetermined number of paper sheets. Is used.

In this paper bundle banding device, the band feeding tape is fed by the tape feeding mechanism, one end of the band sealing tape is sandwiched in the paper bundle, and in this state, the paper bundle is clamped by the clamp member, and the band sealing tape is clamped so that it can be fed out. A rotary ring provided with a chuck member is arranged so as to surround the paper bundle, and the band-sealing tape is chucked by the chuck member, and the rotary ring is rotated to wind the band-wrapping tape around the paper bundle. The other end is overlapped with the already wound portion and fixed by means of thermocompression bonding or the like.

Here, the clamp member has a fixed-side support and a movable-side clamp plate, and the bundle of papers can be attached and detached by bringing the clamp plate into and out of contact with the support. Moreover, in order to prevent the bundle of sheets from being loosened, the bundle of sheets can be clamped in a curved state. For this reason, the support is formed with a concave central portion, and both upper and lower sides are expanded. A receiving surface that projects is formed, and a convex arcuate pressing surface is formed on the clamp plate that is joined to this support. Then, the paper bundle is inserted between the clamp plate and the support in a state where the clamp plate of the clamp member is separated from the support, and then the clamp plate is moved in the direction close to the support, and the paper bundle is moved. I'm trying to clamp it.

Then, in order to feed the sheet bundle to a position where it can be clamped by the clamp member, a sheet bundle guide device is attached in the middle of the sheet bundle insertion path. As this paper bundle guide device, there has been conventionally used a paper bundle guide device configured by a guide plate that guides the paper bundle in a state of abutting it, and a paper bundle gathering member that presses the paper bundle against the guide plate side. Then, in order to follow the curve when the paper bundle is clamped, the guide plate has a concave shape in the center like the support of the above-mentioned clamp member, and is provided with bulging guide surfaces on both upper and lower sides. is doing. In addition, a paper bundle splitting member for dividing the paper bundle into right and left and sandwiching the band-sealing tape is provided at a position between the paper bundle guide device and the clamp member.

However, when the sheet bundle guide device is configured as described above, when the sheet bundle that has passed through the guide plate reaches the support, the end portion of the sheet bundle strikes the support, especially the upper and lower bulging portions, and strikes the receiving surface. Sometimes it could not be inserted. In particular, the paper bundle is divided into left and right by the paper bundle splitting member, but it is highly possible that the edge of the leftmost paper sheet will hit the support and cannot be guided to the receiving surface. . For this reason, in the paper bundle guide device of the prior art, a flexible thin plate is interposed between the guide plate and the support, and the thin plate guides the paper stack to the receiving surface of the support. It was At the time of band-sealing, the band-sealing tape was wrapped around the thin plate.

[Problems to be Solved by the Invention] By the way, as described above, when a thin plate is interposed between the guide plate and the support and the banding tape is wound together with the thin plate when banding the bundle of paper, This thin plate must be pulled out later, and this work is not only troublesome, but the thin plate may be deformed at the time of winding the banding tape or at the time of pulling out after winding. There were drawbacks such as frequent replacement.

The present invention has been made to solve the problems of the prior art as described above, and has a simple structure, and at the time of banding a paper bundle, without using a member wound around the banding tape together with the paper bundle, smooth It is an object of the present invention to provide a paper bundle guide device capable of surely dividing the paper bundle into right and left, sandwiching the band-sealing tape, and guiding the bundle to the receiving surface of the support. .

[Means for Solving the Problems] In order to achieve the above-mentioned object, the paper bundle guide apparatus according to the present invention has a concave center portion and upper and lower side portions of a fixed side having a receiving surface. A clamp member is formed by disposing a movable-side clamp plate having a convex arc-shaped pressing surface so as to be able to come into contact with and separate from the support, and the clamp member is arranged inside the rotary ring so that a predetermined number of sheets of paper can be bundled. After inserting into the rotary ring, inserting the band-sealing tape into the paper bundle, and clamping the curved band with the clamp member, the rotary ring chucks the band-sealing tape and rotates the rotary ring. A paper bundle band-sealing device configured to wind the band-wrapping tape around a paper bundle by means of a clamp plate on the upstream side of the arrangement position of the clamp member in the paper-bundle insertion path. On the side where is located, a sheet bundle gathering member that is provided so as to be inclined so that the plate body having springiness is inserted into the sheet bundle insertion path toward the downstream side direction,
A guide plate is provided so as to face the paper bundle shifting member with the paper bundle insertion path interposed therebetween, and the central portion has a concave shape. On the guide surface, a guide lever protruding into the paper bundle insertion path is attached to a position downstream of the most protruding position of the paper bundle pulling member into the paper bundle insertion path so as to be retractable from the guide surface. A paper bundle splitting member having a guide portion of the band-sealing tape is mounted at a position between the gathering member and the guide lever so that the paper bundle splitting member can be retracted from the insertion path of the paper bundle. .

[Operation] The present invention is configured in this way, and when the sheet bundle is displaced toward the clamp member to perform band-sealing, the sheet bundle is first guided by the sheet bundle pulling member. In this way, while being guided by the paper-bundle pulling member, the tip thereof reaches the position where the paper-bundle splitting member is disposed, and the paper-bundle splitting member divides the paper bundle into left and right. At this time, the leading edge of the sheet bundle is not in a free state but is guided on one side, so that the biting position of the sheet bundle splitting member with respect to the leading edge of the sheet bundle is always constant, and for example, the left and right sides are almost the same. It can be divided evenly. Moreover, one side of the divided sheets is in a substantially free state, so that the sheets can escape in this direction at the time of division, the sliding resistance is small, and the sheet bundle can be divided very smoothly. Become. However, since the guide member is arranged on the side opposite to the paper bundle bringing member to regulate the deviation of the paper bundle to some extent, even after the paper bundle is divided by the paper bundle splitting member, the leading end portion of the paper bundle is Even if it warps, it does not largely deviate from the paper bundle insertion path.

Then, when the sheet bundle further advances, the side that is in the free state after being divided is guided by the guide lever provided on the guide surface of the guide member, and the leading end portion of the sheet bundle is guided in the direction away from the guide surface. Therefore, the sheet bundle is smoothly guided on the receiving surface of the support when it advances to the position where the fixed support that constitutes the clamp member is disposed. In this state, the band-sealing tape guided by the paper bundle dividing member is sandwiched in the paper bundle, the paper bundle dividing member is separated from the paper bundle, and then the movable side clamp plate is moved to the support side. The paper bundle is securely clamped by the clamp member. At this time, when the clamp plate is operated to clamp the sheet bundle, the guide lever retracts into the guide plate due to the clamping force, and there is no problem in deforming the sheet bundle into the curved state.

After that, the banding tape is wrapped by winding the banding tape around the paper bundle. However, since the member for guiding the paper bundle is not wound around the banding tape, It will be taken out smoothly.
