Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper receiving device provided in a sheet discharging device, and more particularly to a so-called shutter type paper receiving device in which a plurality of round bars or pipes are connected in a shutter shape.

[0002]

[Prior art]

 For example, as in the paper ejection device of a sheet-fed printing press, a sheet (hereinafter referred to as paper) is conveyed to a paper ejection port by a chain with a gripper, and is continuously dropped and ejected. In the equipment, a paper receiving device is provided to operate the machine without stopping it when performing a setup change when paper is fully loaded on the paper output tray.

A so-called shutter type paper receiving device is one of the paper receiving devices of this type. The shutter type paper receiving device is provided below the chain with a gripper, and a shutter in which the paper receiving rod is connected in a saw-like shape is guided by a guide rail provided along the chain with a gripper, Always retract from the above paper discharge port. At the time of the above setup change, the shutter is inserted between the paper continuously falling from the chain with the gripper at a timing to block the above-mentioned paper discharge port, and the falling paper is received by the paper receiving rod. As soon as the paper ejection tray is ready, the paper on the paper ejection tray is moved to the ejection tray while retracting the paper ejection rod.

Conventionally, this type of shutter-type paper receiving device is configured by connecting a plurality of paper receiving rods 101 having bearings 10 2 and sprockets 103 at both ends with a connecting plate 104, as shown in FIGS. The sprocket includes an endless chain 106 that forms the cutter 100, engages the bearing 102 with the guide rail 105, and rotates the paper receiving rod 101 together with the sprocket 103 as the paper receiving rod 101 moves. A chain 107 is provided on the upper and lower sides of 103, and is used to move and drive the plurality of paper receiving rods 101. A drive sprocket 108 is meshed with the chain 107. Further, the drive chain 107 is provided with a slip stopper 109 so that the paper can be transferred to a paper discharge tray (not shown).

[0005]

[Problems to be solved by the device]

 However, the above paper receiving device requires as many sprockets 103 as there are paper receiving rods 101. Further, since the chain 106 is wound around the sprocket 103, a chain having a length twice that of the shutter 100 is required, which increases the weight. Further, since the drive chain 107 is required in addition to the chain 106 described above, there is a problem that the guide rail 105, which is a supporting portion thereof, becomes large in size, and the entire apparatus becomes large in size and weight increases.

In view of the above circumstances, it is an object of the present invention to make a shutter-type paper receiving device light and compact.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the paper receiving device of the present invention has guide rails on the delivery frames on both sides below the chain with a gripper that conveys and discharges sheets, respectively along the chain with a gripper. Attach the roller guides of the roller chain to the guide rails, and attach both ends of the paper rod in the shape of a saw to each one roller chain to form a shutter. The roller chain is attached to the roller guide. Each of them is movably supported, and the roller chain is equipped with a drive mechanism, and when the sheets are loaded on the output tray, the shutter is inserted between the sheets that continuously drop from the chain with gripper. It is characterized by receiving the sheet.

[0008]

[Action]

 With the above structure, the roller chain can be moved along the chain with the gripper by being guided by the roller guide part of the guide rail by the drive mechanism, and the plurality of paper receiving trays supported by one roller chain on each side. When a stack of sheets is loaded on the paper output tray, the shutter composed of a rod can be inserted between the sheets continuously falling from the chain with gripper to receive the sheets. Then, the shutter can be evacuated from the above-mentioned paper ejection tray at any time.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a paper discharge device provided with a paper receiving device of the present invention, and illustrates an example in which two paper discharge parts are provided. Reference numeral 1 is a paper feed cylinder, 2.3 is a paper output cylinder provided on the paper feed cylinder 1 in two steps, and 4.5 is an upper part of the paper output cylinders 2.3 and two paper output sections 6 and 7. A chain with a gripper that hangs between the sprocket 8 and 9, respectively, conveys the sheet P selectively delivered from the paper feed cylinder 1 above the paper ejection trays 10 and 11. Then, the sheets are continuously dropped and discharged from the respective sheet discharge ports 12 and 13.

The paper receiving apparatus of the present invention can be applied to any of the above-described two paper discharge units 6 and 7 provided or a single paper discharge unit provided. Hereinafter, for convenience of description, the sheet discharge unit 7 on the right side (lower stage) in the drawing will be described.

In the paper receiving device of the present invention, below the chain 5 with a gripper that conveys and discharges the sheet P, the guide rails 21 and 21 are attached to the delivery frames 20 and 20 on both sides to the chain 5 with the gripper. The guide rails 21 and 21 on both sides are provided with roller guide portions 21c and 21c of the roller chains 22 and 22, respectively, and both ends of the paper rod 23 are slid like one roller chain 22 and 22 respectively. The shutter A is attached to form the shutter A, and the roller chains 22 and 22 are movably supported by the roller guide portions 21c and 21c, respectively, and the drive mechanism 24 is provided on the roller chain 22 and is placed on the paper ejection tray 11.
