Description

[Detailed description of the invention] The present invention relates to the configuration of a stacker in a form processing device, and in particular, in a device that is equipped with a plurality of stacker pockets stacked one above the other, the stacker table in the upper level is placed on the underside of the stacker table to discharge the stacker to the lower stacker. A stopper is provided to adjust the length of the form in the ejection and movement direction of the form, and when the length of the form used exceeds the length of the stacker table, the stopper is installed at the hinge part at a height of about 90 mm. The present invention relates to a stacker which is rotated by .degree. and is click-held by a cam of a hinge portion and a spring pressurizing means to hold the stopper as an extension of an upper stacker table.

Conventionally, the form stopper in the stacker pocket of the device has been configured to protrude from the upper surface of the corresponding table. However, in such a configuration, the top surface of the stacker table needs to be flat because it needs to support the form.If you try to configure the stopper to be adjustable according to the length of the form, you need to make a notch in the table and remove the sliding mechanism from the table. If a function is added to this mechanism to tilt or rotate the stopper in the direction of ejection and movement of the form for convenience of operation when taking out the form, the mechanism becomes even more complicated. was. Furthermore, if the stopper is constructed by standing up from the top of the corresponding table, there is a problem that when a certain number of forms are accumulated in the corresponding stacker, they overflow from the top of the stopper.

In view of the above background, the present invention overcomes the above drawbacks by equipping the upper stacker table with the form stopper of the relevant stacker, and also makes the stopper member rotatable in the sliding direction of the stopper. The upper table can be rotated approximately 90 degrees and stopped at an extended position on the upper surface of the upper tail to make it easier to take out the form when taking out the stacker table. The purpose of the present invention is to obtain a configuration of a stopper that can be used as a stopper, and the feature of the present invention is to achieve the above-mentioned purpose in a stacker of a form processing device in which a plurality of stackers are arranged one above the other. A holding member is provided on the lower surface of the table, and the holding member is slidable along the lower surface with a frictional holding force in the form ejection direction, and the other degrees of freedom are fixed. a stopper member rotatably supported by the hinge portion and having a cam portion from the center of rotation, the cam portion being pressurized by the spring pressure means; The stacker is constructed by click-holding the stopper member at a predetermined rotational position using a cam and a spring pressure means, and will be explained based on the following figures.

FIG. 1 is a conceptual diagram of a general example of a form processing device.

In the figure, 1 and 2 are two stackers stacked one above the other, 3 is a hopper, 4 is a form, 5 is a form feeding and distributing means, and 6 is the entire processing device. In the illustrated example, there are two stackers, and the forms 4 on the hopper 3 are fed, fed, subjected to necessary processing, distributed, and discharged to one of the stackers. Note that various sizes of forms are used even in the same device, and if the stacker table is enlarged to accommodate large forms, it will be difficult to handle small forms, and even though the device becomes larger, Considering that small forms are usually used most often, it is necessary to devise measures such as making the stacker table extendable.

FIG. 2 is an explanatory diagram of a movable stopper/extension table of a stacker according to an embodiment of the present invention. The figure is a sectional view from the left front in Figure 1,
Shows stacks stacked one above the other.

In the figure, 7 is a guide shaft attached to the upper table 1 of the stacker, and 8 is a holding member consisting of leg parts 8a and 8b that fit and slide on the guide shaft, a plate spring fixing part, and a support part for the hinge shaft 11. ,
9 is a plate spring for pressurization, and 10 is a holding member 8 for holding the spring.
11 is a hinge shaft, 12 is a stopper member, 12a is a cam portion of the stopper member that comes into contact with the leaf spring 9, and 13 and 14 are discharge rollers of the stacker. The holding member 8 carrying the members 9 to 12 is attached to the guide shafts 7 and 8a,
8b, and is configured to be able to slide in the direction of the arrow along the guide shaft 7. If necessary, it is held by appropriate friction increasing means, such as biasing by a spring, and the form 4 is It is adjusted and set according to the longitudinal size. On the other hand, a stopper member 12 is rotatably mounted on the holding member 8 via a hinge shaft 11, and a cam-shaped portion 12a centered around the hinge shaft 11 is formed in a part of the stopper member 12. A leaf spring 9 is pressed against the cam-shaped surface. Although the stopper member 12 is rotatable by the operator's manual operation, it is clicked and held at a stable position determined by the cam shape 12a and the leaf spring 9, as indicated by solid lines and broken lines in FIG. It is constructed so that it can take at least the two positions shown.

Then, with the configuration as above, one position is used as a stopper for the form for the lower stacker,
In the case where the lengthwise size of the form exceeds the dimension of the stacker table 1 by making the other side surface of the stopper member 12 substantially flush with the extended surface of the table of the upper stacker 1 in the other position. In this case, a form can be supported as an extension of the stacker table.

Note that configuring the stopper to descend from the top is to prevent the form 4 sent out at a certain speed by the ejection roller 13 or 14 from jumping forward due to inertia or the like. There is no need to restrict the bottom of the stacker table, and there is no problem even if the bottom is open, and when taking out a form, the structure of the present invention allows the stopper member 12 to be rotated and knocked down, making it easy to put your hand in during operation. This is also an advantage of this configuration.

As explained above, according to the present invention, it is possible to realize a stacker configuration that can be used as a stopper for the lower stacker when using small forms and as an extension of the table of the upper stacker when using large forms, with an extremely simple structure. , it can contribute to miniaturization of the device and improvement of operability.
