Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a left column and a right column, which are positioned on the left and right with respect to one row, and cut sheets that are sequentially fed in one row. The present invention relates to a cut sheet sorting device that selectively sorts and feeds the cut sheet so that the cut sheet is fed along any one selected row.

[Prior Art] A photographic processing apparatus that supplies exposed photographic paper to a processing unit to perform processing such as development and fixing, particularly in a so-called minilab apparatus that performs a consistent process from exposure to development, 2. Description of the Related Art A sorting device is known in which cut sheets sequentially fed in one row downward are sorted into three rows or two rows using a carrier conveyor belt and the cut sheets are fed.

In such an apparatus, the photographic paper (cut paper) that has been exposed in the exposure unit is first transferred to the processor unit (development processing unit) for transporting each processing unit by a number of transport rollers. Even if there is a slight misalignment when receiving the paper, the misalignment gradually becomes large during transportation, and there is a drawback that paper jam easily occurs.

For this reason, it is necessary to directly feed from the exposure section to the receiving section (roller section) of the processing section.

Further, the conventional conveyor belt has a drawback that it is difficult to send the posture control for keeping the cut paper straight.

Further, in the conventional sorter of this kind, the mechanism of the sorter is complicated, so that the processing speed cannot be increased and the sorter has a large size.

[Problems to be Solved by the Invention] The object of the present invention is to eliminate the drawbacks of the conventional apparatus as described above, and to put cut sheets sequentially fed in one row on the left and right sides of the one row. A sorting speed is increased when the cut sheets are selectively sorted and fed so as to be fed in a correct orientation position along a row, a right row, and any one selected from the one row. Another object of the present invention is to provide a compact cut sheet allocating device having a simple structure that can accurately distribute and feed cut sheets.

[Means for Solving the Problems] In order to solve the above-mentioned object, the present invention provides cut sheets sequentially fed in a row along a guide plate to a left column and To receive and hold the cut sheet in order to selectively distribute and feed the cut sheet so as to be fed along any one row selected from the right row and the one row A position that is swung into the one row and a position that is returned to the left row and is swung to a position where the held cut sheets can be fed along the left row and separated from the one row. Sorting member, a position that is swung in the one row so as to receive and hold the cut sheet, and a position that is returned to the right row and can feed the held cut sheet along the right row The right sorting member which is swung to the left to be separated from the one row, and the restored left swing member. Holding device for releasing the holding so as to feed the cut sheet held by the cutting member along the left column, and the cut sheet held by the restored right sorting member in the right column. It is characterized by comprising a holding release device for releasing the holding so as to be fed along.

The left allocating member and the right allocating member respectively have a rectangular plate main body, and upright holding edges are formed on the bottom side of the main body and the side side facing the one row, and protrude from the back part of the guide plate when positioned at the return position. An opening that is aligned with the holding release position may be formed in the rectangular plate main body so that the holding release device releases the cut sheet and feeds it when the cut sheet is held and returned to the return position.

Unlike the above, when the left sorting member and the right sorting member are respectively in the restored upright position, the side wall opposite to the one row is opened to form an opening for receiving the cut sheet, and the bottom wall is released. It is made into a box shape with an openable bottom plate that constitutes the device, and after the sorting member holds the cut sheet and is swung to the return position, the openable bottom plate is opened and the cut sheet is released. It can be made to be fed.

Furthermore, a pair of feed rollers is provided on the lower wall of the box-shaped main body, and after the sorting member holding the cut paper is restored, the feed roller is operated to send out and feed the cut paper. You can also do it.

[Operation] With the configuration described above, when the cut sheets fed along one row are distributed to the left row and fed, the left sorting member is swung into the one row and cut. By receiving and holding the paper, swinging the paper back in the left row, and moving the holding release device to the release position, the held cut paper can be fed along the left row. In the same manner, when the sheets are sorted into the right row and fed, the right sorting member is swung into the one row to receive and hold the cut sheet,
It is possible to feed the cut sheets held along the left row by swinging the holding release device back to the right row and moving the holding release device to the release position. Further, when feeding along the one row, if the left sorting member and the right sorting member are not oscillated and are left stationary in the left column and the right column respectively, both the left sorting member and the right sorting member are in the one column. Since it is in a position separated from the sheet, the fed cut sheets can be fed along the one row.

[Embodiment] FIG. 1 is a view for explaining the operation principle of the distribution and feeding of cut sheets according to the present invention.

The cut sheets 2 sequentially fed along one row are the guide plates 3

The left distributing member 6 is composed of a plate-shaped main body 6a, an upright bottom edge 6b that is bent from the lower edge of the plate-shaped main body 6a, and an upright side edge 6c that is bent from the side edge facing the row A and stands up. It is indicated by an arrow a from the upright position shown in FIG. 2 by a drive motor or a rotary solenoid 7 provided on the back of the guide plate 3 which is pivotally supported on the plate 3 at the lower right corner by a pivot shaft 6d. As described above, it is swung in the clockwise direction along the guide plate 3 and then swung between the cut sheet receiving positions located in the central one row A through the inclined position shown in FIG. There is. The left distributing member 6 is formed with an extrusion opening 6e. This extrusion opening 6
The position e is aligned with the push-out lever 8 constituting the holding release device provided along the guide plate 3 when the left sorting member 6 is returned from the above-mentioned tilted position to the upright position after receiving the cut sheet 2. When the upright bottom edge 6b of the left distributing member 6 pushes the L-shaped bent upstanding arm 8a of the pushing lever 8 downward, the pushing lever 8 is moved to the pivot axis c.
Is oscillated in the clockwise direction around the arrow, and the pushing lever 8 is pushed forward through the pushing opening 6e. The push-out lever 8 is always held in a counterclockwise oscillating position in contact with the guide plate 3 as shown in FIG. 3 by elasticity or by its own weight. Only when 6 is swung to the upright position is it pushed forward through the pushing opening 6e as shown in FIG. In this way, the left distributing member 6
When the cut sheet 2 is received and swung to the upright returning position, the cut sheet 2 held by the cut sheet 2 can be extruded into the row B and fed along the row B.

Unlike the above description, when the folding lever is not provided on the pushing lever 8, when the left sorting member 6 receives the cut sheet 2 and is swung to the upright returning position, the pushing lever 8 is moved forward by an operating device (not shown). It can also be extruded, and by doing so, the operation timing can be freely controlled.

In exactly the same manner, the right distributing member 9 is pivotally supported on the guide plate 3 by the pivot shaft 9d at the lower left corner thereof, and is vertically erected by the drive motor or the rotary solenoid 10 as shown in FIG. It is possible to swing between a return position aligned with C and a cut sheet receiving position positioned in the first row A by being swung counterclockwise as indicated by arrow b from this position. The right allocating member 9 has an upright side edge 9b that is bent from the lower edge of the rectangular plate body 9a and stands upright, and an upright side edge 9c that is bent from the side edge facing the first row A and stands upright. When it is in the position, the pushing opening 9e for passing the pushing lever 11 provided along the guide plate 3 is formed, and when the cut sheet 2 is received and returned to the upright position, the right sorting member 9 is erected. The bottom edge 9b is an L-shaped bent standing arm 11 of the push-out lever 11.
