Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stacker device that stacks forms fed one after another almost horizontally.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 4 and 5, the forms 1 are discharged from the discharge roller 2 one after another almost horizontally, and the forms 1 are obliquely moved downward by the guide means 3 arranged on the upper side of the travel path of the form. The support guide disposed at the end of the belt conveyor 4 while being transported at a lower speed than the discharge speed of the discharge roller 2 by the belt conveyor 4. A stacker device 6 that is configured to start up and accumulate along line 5 is known. The guide means 3 used here is usually made of sheet metal, and extends so as to extend from the base portion 3a in a direction transverse to the feed direction (arrow A direction) of the form by the discharge roller 2. And a plurality of guides 3b arranged in parallel to each other at intervals in the transverse direction with respect to the feed direction of the form, and the plurality of guides 3b are arranged at intervals on the discharge roller 2. The plurality of roller portions extending obliquely downward are prevented, the form 1 fed at high speed by the discharge roller 2 is prevented from jumping up, and is guided obliquely downward.
[0003]
[Problems to be solved by the invention]
However, in such a conventional apparatus, there is a problem that the form 1 fed from the discharge roller 2 rides on the guide 3b and is caught to cause a jam.
[0004]
As a result of studying the cause of the above-described problems, the present inventors have 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 in parallel with the feed direction of the form, depending on the size or feed position of the form 1, the edge 1a of the form and the edge 3c of the guide 3b In this case, the form climbs over the guide or gets caught and jams.
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 caught by a guide and causes jamming, and enables a good accumulation of forms.
[0005]
[Means for Solving the Problems]
According to the present invention, of a plurality of guide edges provided on a guide means for guiding a form fed substantially horizontally from a discharge means such as a discharge roller to the side facing the central axis of the feed by the discharge means, The inner edge is inclined outwardly away from the central axis of the feed as it goes 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 outward as the form progresses. There is no danger of slipping away from the edge and catching the slip on the guide.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is arranged on the upper side of a travel path of a form fed almost horizontally from the discharge means, and includes a guide means for directing the form obliquely downward, and a support means for receiving and collecting the fed forms. In the apparatus, the guide means is a plurality of guides arranged at intervals in a lateral direction with respect to a feed direction of the form by the discharge means, and a plurality of guides are directed obliquely downward by a lower surface of the guide. Each of a plurality of guides arranged on both sides of the central axis of the feed by the discharging means and at a position deviating from the central axis among the plurality of guides is a central axis of the feed by the discharging means facing side of the edge, is inclined outwardly so away from the center axis of the feed toward the downstream of the feed direction, the opposite edge Characterized in that it is parallel to the central axis of the feed. With this configuration, even if the edge of the fed form overlaps with the inner edge of one guide, as the form progresses, it moves away from the edge that spreads outside the guide. It falls down without being caught by the guide and is collected by the support means. Here, the guide means is arbitrary such as those made of sheet metal or plastic. The inclination formed on 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 applying an inclination to the inner edge, it is not always necessary to apply an inclination to the inner edge for all the guides, but only for the guide of the part that may be in contact with the edge of the form to be handled. What is necessary is just to give inclination.
[0007]
The stacker device of the present invention is a form of any form, for example, a form consisting of a single form, a form in which paper is folded, a form in which paper is folded and bonded, a postcard or a sealed letter, a plurality of single forms Can be used for collecting forms and the like created by collating, and can be used in combination with any form processing apparatus. Specific examples of the form processing apparatus include an apparatus that cuts and discharges continuous forms printed by a printer into individual forms, an apparatus that folds the continuous forms and cuts and discharges them into individual forms, and folds continuous forms. An apparatus that stacks, cuts into individual forms, and further stacks and discharges the sheets, an apparatus that stacks and stacks a plurality of single sheets, and the like can be exemplified.
[0008]
Further, in the stacker device of the present invention, as a support means for receiving and accumulating the fed forms, any form capable of accumulating the fed forms can be adopted. For example, the fed forms are horizontally arranged. And using a conveyor configured to stack and stack along a support guide placed at a stacking position, or using a support stand that simply receives the fed forms horizontally and stacks them as they are be able to.

【Example】
Hereinafter, embodiments in which the stacker device of the present invention is combined with a burster device will be described. FIG. 1 is a schematic side view showing a burster device 14 and a stacker device 6A according to an embodiment of the present invention combined therewith, FIG. 2 is a schematic perspective view of the main part of the stacker device, and FIGS. ) Are a schematic plan view and a schematic side sectional view of the main part of the stacker device, and the same components as those in the conventional example shown in FIGS. 4 and 5 are denoted by the same reference numerals. In FIG. 1 to FIG. 3, 14 is a burster device, a first feed roller 15 for pulling out the continuous form 1 </ b> A, a second feed roller 16 that rotates at a faster speed than the first feed roller 15, A blade 17 disposed at a position in contact with the continuous form 1A between the first feed roller 15 and the second feed roller 16; a discharge roller 2 disposed downstream of the second feed roller 16; The form 1A is cut into individual forms 1 by using the horizontal perforations formed in the continuous form 1A, the speed difference between the first feed roller 15 and the second feed roller 16, and the blade 17, and the discharge roller. It becomes the structure discharged | emitted one after another by 2. The discharge roller 2 constitutes discharge means for feeding a form to the stacker device 6A.
[0010]
The stacker device 6A is disposed at a position for receiving the form 1 fed from the discharge roller 2, and is disposed on the upper side of the travel path of the form 1 fed at high speed from the discharge roller 2 to prevent the form 1 from jumping up. The guide means 3A for guiding downward, the belt conveyor 4A that receives the form 1 and transports it almost horizontally and at a lower speed than the discharge speed of the discharge roller 2, and is provided at the rear end of the belt conveyor 4A. A support guide 5 and the like for supporting the form 1 to be raised so as to stand up in an oblique direction are provided. The guide means 3A used here includes a base portion 3Aa extending in the lateral direction with respect to the feed direction (arrow A direction) of the form by the discharge roller, and the form so as to extend from the base portion 3Aa, as in the prior art. A plurality of guides 3Ab arranged substantially parallel to each other at intervals in the lateral direction with respect to the feed direction, and the plurality of guides 3Ab feed the form 1 fed by the discharge roller 2 to the lower surface of the guide 3Ab. However, unlike the conventional guide, the guide 3Ab is disposed on both sides of the central axis OO of the feed by the discharge roller 2 and deviates from the central axis OO. The edge 3Ac of the guide 3Ab at the position facing the center axis OO of the feed is moved toward the downstream in the feed direction. It is inclined outwardly so away from the center axis O-O of, and parallel to the opposite edge to the center axis O-O of the feed. The inclination angle α with respect to the feed direction of the edge 3Ac is set to about 0.5 to 2.0 degrees.
[0011]
Also in the stacker device 6A, when the forms 1 are successively fed from the discharge roller 2 of the burster device 14 at a high speed, the guide means 3A guides the forms 1 downward, and the belt conveyor 4 removes the forms 1. It is picked up and transported to the rear end, where it rises in an oblique direction and accumulates. Here, when the form 1 discharged from the discharge roller 2 hits the guide 3Ab of the guide means 3A and is guided downward, the edge 1a of the fed form 1 overlaps the inner edge 3Ac of one guide 3Ab. May be a position. However, even in that case, the edge 3Ac of the guide 3Ab spreads outward as the form 1 progresses, so that it leaves the edge 1a of the form 1, and the form 1 rides on or gets caught by the guide 3Ab. There is no such thing. Thus, always good integration is possible.
[0012]
【The invention's effect】
As described above, the stacker device of the present invention is configured so that the edge of the plurality of guide edges facing the central axis of the form feed by the discharge means, that is, the inner edge, is directed toward the feed direction downstream. In this case, the edge of the fed form is positioned so as to overlap the inner edge of one guide. Since the edge spreads outward, the edge of the form moves away from the edge of the guide, and the form does not get caught on the guide or get caught, and the form can always be collected stably. .
