Abstract

PROBLEM TO BE SOLVED: To prevent a slip from being caught by a guide 3Ab in a stacker device in which the slip horizontally fed at high speed is guided downward by plural guides 3Ab laterally arranged at intervals. SOLUTION: An inside edge 3Ac of a guide out of plural guides 3Ab, which is placed laterally apart from the center axis O-O of feed of slips, is allowed to be inclined so that it spreads outward as a slip proceeds in the feed direction. Thus, even when the edge 1a of the slip 1 fed, is overlapped over the inside edge 3Ac of the guide, the edge of the slip departs from the edge 3Ac as the slip 1 proceeds, and thereby the slip can be prevented from being caught by the guide.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a stacker for stacking documents that are fed almost horizontally one after another.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, forms 1 are successively discharged from a discharge roller 2 almost horizontally, and the forms 1 are directed obliquely downward by a guide means 3 and downward. On a belt conveyor 4 arranged substantially horizontally, and while being conveyed by the belt conveyor 4 at a speed lower than the discharge speed of the discharge roller 2, stands along a support guide 5 disposed at an end of the belt conveyor 4. A stacker device 6 configured to be lifted and integrated is known. The guide means 3 used here is usually made of sheet metal,
A base portion 3a extending in the horizontal direction with respect to the form feed direction (the direction of arrow A), and extending parallel to each other so as to extend from the base portion 3a and spaced apart in the horizontal direction with respect to the form feed direction. , And a plurality of guides 3b extend obliquely downward between a plurality of roller portions arranged at intervals to the discharge roller 2, and the plurality of guides 3b are extended by the discharge roller 2. The form 1 fed at high speed was prevented from jumping up and was guided diagonally downward.

[0003]

However, in such a conventional apparatus, there is a problem that the form 1 fed from the discharge roller 2 runs on the guide 3b and is jammed by being caught.

The present inventors have studied the causes of the above-mentioned problems and found that these problems have occurred for the following reasons. That is, in the conventional guide means 3, since the edge of each guide 3b is formed parallel to the feed direction of the form, the edge 1a of the form and the edge 3c of the guide 3b depend on the size or feed position of the form 1. In some cases, the sheets were overlapped, and in that case, the form slipped on or was caught by the guide, causing a jam. The present invention has been made based on such knowledge, and an object of the present invention is to provide a stacker device that prevents a form from being jammed by a guide and causes jamming, and enables good stacking of forms.

[0005]

SUMMARY OF THE INVENTION According to the present invention, among the plurality of guide edges provided on a guide means for guiding a form which is fed substantially horizontally from a discharge means such as a discharge roller downward, the guide means is provided by the discharge means. The side facing the central axis of the feed, that is, the inner edge, is inclined outwardly away from the central axis of the feed toward the downstream in the feed direction. With this configuration, even if the edge of the fed form overlaps the inner edge of one guide, the edge of the guide spreads out as the form advances, so that the edge of the form is Moving away from the edge,
Reports do not get on or get caught in the guide and get caught.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention comprises guide means arranged so that a form fed from a discharge means substantially horizontally is directed obliquely downward, and support means for receiving and stacking the fed form. In the stacker device, the guide means includes a plurality of guides arranged at intervals in a horizontal direction with respect to a direction in which the form is fed by the discharge means, and the guide is arranged at a center axis of the feed by the discharge means. The edge on the facing side is inclined outwardly away from the center axis of the feed as it goes downstream in the feed direction. With this configuration, even if the edge of the fed form is overlapped with the inner edge of one guide, as the form advances, the edge of the form spreads away from the outer edge of the guide, and therefore, the form becomes It falls down without being caught by the guide, and is accumulated by the support means. Here, as the guide means, an arbitrary one such as a sheet metal member, a plastic member, or the like is available. The inclination formed at the edge of the guide is preferably as small as possible as long as the form can be prevented from being caught, and the inclination angle of the edge with respect to the feed direction is preferably set to about 0.5 to 2.0 degrees.
In addition, when imparting an inclination to the inner edge, it is not always necessary to impart an inclination to the inner edge for all the guides. What is necessary is just to give an inclination.

The stacker of the present invention can be applied to any form, for example, a form formed of a single form, a form in which paper is folded, a form in which paper is folded and pasted, and a postcard or sealed form, a plurality of forms. It can be used to accumulate forms and the like created by collating the single forms described above, and can be used in combination with any form processing device. Specific examples of the form processing device include a device for cutting a continuous form printed by a printer into individual forms and discharging the form, a device for folding the continuous form and cutting and discharging the form to individual forms, and a form for folding a continuous form. Stack,
A device that cuts individual forms, attaches them together, and discharges them.
A device for overlapping and binding a plurality of cut sheets and discharging the cut sheets can be used.

[0008] In the stacker device of the present invention, the supporting means for receiving and accumulating the fed form includes:
Any type of form capable of accumulating fed forms can be adopted.For example, a conveyor configured to transport the form to be fed horizontally, stand up along a support guide arranged at the accumulating position, and accumulate the conveyed forms. And those using a support table that simply receives the form to be fed horizontally and accumulates it as it is.
