Description

[Detailed Description of the Invention] Technical Field The present invention relates to a sheet sorting device, and more particularly to a device for sorting paper sheets such as mail.

BACKGROUND OF THE INVENTION In general, stacked paper mail items are loaded in bundles into special buckets and sent to a bundler by a conveyor. The bucket bag has a substantially U-shaped cross section formed by a bottom plate and a pair of side plates provided on both sides of the bottom plate, and is set on the side plates so that the bucket is oriented parallel to the conveyance direction of the conveyor.

By the way, it is necessary to arrange the accumulation of paper mail before being sent to the bundler, but in the bucket of the above structure, the side plates become an obstacle and it is difficult to align both end faces of the paper mail in the transport direction. Sorting work is difficult. Therefore, there is a drawback that the loaded bucket cart must be once transferred to another bundling lie and left to the bundling means.

Purpose of the invention The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology.The purpose of this invention is to create a structure that allows the stacked paper sheets to be aligned in the bucket, so that the paper sheets can be stacked in a stacking device. It is an object of the present invention to provide a sheet sorting device that can shorten the process time required to complete the process.

Structure of the invention The paper sheet sorting device according to the invention has a substantially U-shaped cross section consisting of a bottom plate and a pair of side plates on both sides, and has a notch in at least one of the side plates extending from its upper end toward the bottom plate to reach the bottom plate. A bucket for loading paper sheets, which has a guide vertical groove and a guide horizontal groove that is connected to the guide vertical groove and is provided on the bottom plate in a direction perpendicular to the side plate, and a guide horizontal groove that is provided parallel to the direction of the guide vertical groove. It is characterized by including a pressing member which can be freely engaged and detached from the bucket by being guided by the bucket.

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

1 to 3 are configuration diagrams showing an embodiment of the present invention, in which, for example, paper mail items 1
As shown in Figure 1, the structure of bucket B for loading bundles of workpieces (hereinafter simply referred to as workpieces) is as shown in Figure 1.
A pair of side plates 3, 3 provided substantially perpendicularly from both ends of the top surface of this bottom plate form a substantially U-shaped cross section. The side plates 3, 3 are attached to the bottom plate 2 at an angle that matches the inclination of a conveyor (not shown). In this structure, the workpiece 1 is loaded on the bottom plate 2 so as to be sandwiched between the side plates 3, 3.

In either side plate 3, 3, there is a vertical guide groove 3 cut out vertically so as to divide it into left and right sides.
A is provided. A concave guide lateral groove 2a is bored in the upper surface of the bottom plate 2 in a direction perpendicular to the side plate so as to communicate with the vertical groove 3a. These vertical grooves 3a and horizontal grooves 2a form one L-shaped guide groove slit 4.

Note that the guide lateral grooves 2a in the bottom plate 2 may be formed by completely cutting out the bottom plate like the guide vertical grooves 3a instead of being formed into concave grooves as in the illustrated example. Moreover, what is formed as one guide groove 4 can be further provided on the opposing side plate side. In this case, the structural strength of the bucket B is taken into account when processing.

Using Figures 2 and 3, set up the bundling work unit U.
I will explain about it. The composition of the bundling work unit U is as follows:
An elevating cylinder mechanism 5 is supported on a base body (not shown) containing a control circuit, and a set of horizontal cylinder mechanisms 6 is further supported at the tip of the actuating rod 5a. Further, at the tip of the differential rod 6a of the horizontal movement cylinder mechanism 6, a bar-shaped or plate-shaped pressing member 7 is suspended and carried perpendicularly thereto. As a result, the pressing member 7 is capable of two-dimensional movement in the vertical direction Y and the horizontal direction X in the figure by the vertical movement and driving of the horizontal movement cylinder mechanisms 5 and 6.

In the above structure, the pressing member 7, which is waiting at a position corresponding to the guide groove 4 provided in the bucket B, is driven by the lifting cylinder mechanism 5 to enter the guide groove 4 and press the member. The height is adjusted to such an extent that the tip end barely fits into the guide groove 2a in the bottom plate 2.

When the position of the pressing member 7 is adjusted in this way,
By driving the horizontal movement cylinder mechanism 6, the pressing member 7
moves horizontally to the right in the figure, crosses the bucket bag B, first passes through the guide vertical groove 3a of the side plate 3, and enters the inside of the bag bag B.

When the pressing member 7 comes into contact with a large number of irregularly stacked works 1 inside the bucket bag B, the group of works 1 is pressed against the other side plate 3 and is shifted to one side. At this time, the tip of the pressing member 7 moves while being engaged with the guide lateral groove 2a of the bottom plate 2, so that it is possible to press all of the workpieces up to the lowest part of the group 1, making it possible to bundle them.

As mentioned above, if the guide grooves 4 of the bucket B are provided so as to face each other on both sides 3, 3, instead of just one guide groove 4, pressure can be applied to the group of works in the bucket B from either the left or right direction. This makes it possible to increase the degree of freedom in bundling work. Furthermore, although the pressing member 7 is configured to perform two-dimensional movement in the X and Y directions by the operation of both cylinder mechanisms 5 and 6, it is also possible to move the base body in the bundling work unit U in a direction perpendicular to the drawing, that is, in the Z direction. By configuring the bucket cart B to be movable, the pressing member 7 can be freely adapted to the bucket cart B at any location without limiting the positioning of the bucket cart B on the conveyor.

Effects of the invention As described above, according to the invention, there is no need to transfer paper sheets such as mail accumulated in a bucket to another line for sorting, and the paper sheets can be stacked on the same conveyor line. Since the bundles are efficiently sorted and sent to the post-bundle device, the process time can be significantly reduced.
