Description

[Detailed description of the invention] The present invention relates to a paper sheet transfer mechanism.

Generally, in an automatic paper processing device, stacked paper sheets are transferred from a first conveyance mechanism to the first conveyance mechanism.
There may be cases where it is necessary to transfer the material to a second transport mechanism located at a higher position than the second transport mechanism.

FIGS. 1 and 2 are schematic diagrams for explaining the transfer operation from a first conveyance mechanism to a second conveyance mechanism including the paper sheet transfer mechanism of the present invention and the conventional paper sheet transfer mechanism.

That is, as shown in FIG. 1, when transferring paper sheets 2 on a plurality of first transport mechanisms 1a to 1z to one second transport mechanism 3, or as shown in FIG. When it is desired to distribute the paper sheets 2 on the first transport mechanism 1 for books to the plurality of second transport mechanisms 3a to 3z, the paper sheets 2 are transferred by the paper sheet transfer mechanism 4.

A conventional paper sheet transfer mechanism includes a bucket that is made up of two side plates and a bottom plate, on which the paper sheets transferred from the first transport mechanism are mounted, and a bucket that is installed at a higher position than the first transport mechanism. a transfer stop detection means for detecting a transfer stop position of the bucket when transferring the paper sheets to the second conveyance mechanism, and a transfer stop position detection means for raising the bucket. a bucket drive mechanism for stopping the bucket when the transfer stop position is detected; and a pushing mechanism for pushing out the paper sheets loaded on the stopped bucket from the bucket to the second transport mechanism. It consists of:

Next, a conventional paper sheet transfer mechanism will be explained with reference to the drawings.

FIG. 3 is a perspective view showing a conventional example.

The paper sheet transfer mechanism shown in FIG. 3 includes a bucket 5 having two side plates and one bottom plate, a bucket drive mechanism 6 that drives the bucket 5 in the vertical direction, and detects the transfer stop position 7 of the bucket 5. A stop position detection means 8 for transporting the paper sheets 2 from the bucket 5 to the second transport mechanism 3, a guide plate 9 provided along the moving part of the bucket 5 to prevent the paper sheets 2 from falling off the bucket 5, and 2 and a control section 11 that controls the operation of each mechanism.

In FIG. 3, paper sheets 2 transported by the first transport mechanism 1 are transferred to a bucket 5 by a transfer means (not shown). The bucket 5 is moved upward by the bucket drive mechanism 6 to the transfer stop position 7.
It stops when the stop position detection means 8 confirms that the stop position has been reached. Bucket 5 is at transfer stop position 7
When the push-out mechanism 10 stops, the push-out mechanism 10 pushes out the paper sheets 2 to the second transport mechanism 3, and the transfer of the paper sheets 2 from the first transport mechanism 1 to the second transport mechanism 3 is completed.
FIG. 4 is a block diagram for explaining the conventional control system shown in FIG. 3.

The paper sheets 2 transferred from the first transport mechanism 1 to the bucket 5 are as shown in FIG. When the paper sheets 2' are transferred to the bucket 5, the paper sheets 2' which protrude due to the influence of the guide plate 9 when the paper sheets 2' are lifted up by the bucket 5 to the transfer stop position 7 are in a state as shown in FIG. 5b. If you try to push this out with the push-out mechanism 10 as it is, the protruding paper sheets 2' will get caught in the gap between the bucket 5 and the push-out mechanism 10, preventing normal transfer, and the protruding paper sheets will be damaged. It was hot.

A drive mechanism that drives the bucket in the vertical direction, a means for detecting a transfer stop position when transferring paper sheets from the bucket to the second transport mechanism, and a guide plate provided along the moving part of the bucket. 2nd from Bucket
comprising a push-out mechanism for pushing out paper sheets to the conveyance mechanism and a control section for controlling each mechanism, and a means for detecting the protrusion of paper sheets from the bucket at the transfer stop position, and the bucket drive mechanism Once the bucket is raised from the transfer stop position, the tip of the sheet protruding into the gap between the bucket and the extrusion mechanism is raised to a position higher than the upper end of the extrusion mechanism, and then lowered and transferred. The bucket cart is configured to be able to stop when the stop position detection means detects the transfer stop position.

That is, the paper sheet transfer mechanism of the present invention is provided with means that can detect the protrusion of paper sheets from the bucket when the bucket stops at the transfer stop position, and furthermore, the bucket drive mechanism moves the bucket to the transfer stop position. The tip of the paper sheet protruding into the gap between the bucket and the extrusion mechanism is raised to a position higher than the upper end of the extrusion mechanism, and then lowered to detect the transfer stop position detection means. The bucket cart is configured to be able to stop when the transfer stop position is detected.

Next, embodiments of the present invention will be described with reference to the drawings.

6a, b, and c are a top view, a front view, and a side view showing one embodiment of the present invention.

The paper sheet transfer mechanism shown in FIGS. 6a, b, and c shows a state in which the bucket 5 is stopped at the transfer stop position 7, and a protrusion detection function that can detect the protrusion of paper sheets 2 from the bucket 5 is shown. Means 12 are provided.

The operation of the paper sheet transfer mechanism shown in FIGS. 6a, b, and c will be explained with reference to side views for explaining the driving operation of the bucket bag shown in FIGS. 7a, b, and c.

The presence of paper sheets 2' protruding from the bucket 5 stopped at the transfer stop position 7 is detected by the protrusion detection means 12 as shown in FIG. 7a. Then, as shown in FIG. 7b, the bucket 5 is driven further upwards from the transfer stop position 7 by the bucket drive mechanism 6, and the tip of the protruding paper sheet 2' is placed higher than the upper end of the extrusion mechanism 10. Free the protruding paper sheets 2'. Thereafter, as shown in FIG. 7c, the bucket 5 is lowered by the bucket drive mechanism 6 and returns to the transfer stop position 7, so that the paper sheets 2' that have protruded are accommodated between the bucket 5 and the push-out mechanism 10. The extrusion operation performed by the extrusion mechanism 10 in this state will be performed normally.

FIG. 8 is a block diagram for explaining the control system of the embodiment shown in FIGS. 6a, b, and c.

As explained above, according to the present invention, a stable and safe paper sheet transfer mechanism can be realized with a simple mechanism.

In the above-mentioned embodiment, the protruding sheet detection means is provided, and only when the protruding paper sheet is detected, the bucket is driven above the transfer stop position and then lowered, thereby detecting the protruding paper sheet. When the bucket is not loaded, it can be stopped at the transfer stop position without being driven above the transfer stop position, reducing the transfer time. However, if there is no protrusion detection means, the bucket is always By driving the paper sheet above the transfer stop position and then lowering it, the overflowing paper sheets can be placed between the extrusion mechanism and the bucket, just as when there is an overflow detection means, so the bucket can be moved. Any paper sheet transfer mechanism having a bucket drive mechanism that can be driven upward from the loading stop position and then lowered is within the scope of the claims of the present invention.

The paper sheet transfer mechanism of the present invention changes the driving operation of the bucket drive mechanism, and instead of raising the bucket and stopping at the transfer stop position, the paper sheet transfer mechanism of the present invention drives the bucket to above the transfer stop position and then By lowering it and stopping it at the transfer stop position, the overflowing paper sheets can be stored between the extrusion mechanism and the bucket, so they can be prevented from getting caught between the extrusion mechanism and the bucket. This has the effect of preventing damage to protruding paper sheets.
