Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a paper feeding device for feeding printing paper to a paper feeding device of a sheet-fed printing press, for example.

<Prior Art> Conventionally, when supplying printing paper of a sheet-fed printing press to a printing press,
There is a method in which sheets are stacked by obtaining them with a sheet feeding device or the sheets are piled up on a mounting table externally and directly conveyed to a sheet feeding device using a carrier. In this case, the former requires the printing machine to be stopped while the paper is being stacked, and the latter is difficult to position the paper vertically and horizontally with respect to the paper feeding device when carried by the carrier. There is also a drawback that it takes time to locate the position.

Therefore, a paper feeding device is installed in front of the paper feeding device.

This paper feeding device has two rulers for positioning the paper with respect to the paper feeding device. After positioning the printing paper stacked on the trolley device via a mounting table by the ruler, the trolley device is railed. , And conveys the printing paper by a conveyor or the like, and sends the printing paper to a paper feeding device.

<Problems to be solved by the invention> By the way, when the printing paper loaded on the mounting table is placed on the truck device or the like by using the carrier, it is necessary to use a vehicle such as a forklift. There is a problem that it is expensive, a dedicated driver is required, and the vehicle cannot be entered in a narrow space.

The present invention has been made to deal with the above-mentioned circumstances,
It is possible to provide a paper feeding device that allows a printing paper loaded on a mounting table to be carried by a carrying device such as a hand lift that can be manually operated and that anyone can easily position it at a predetermined position. To aim.

<Means for Solving the Problems> The present invention has been made to solve the above problems.
The trolley device that reciprocates between the sheet feeding device of the sheet-fed printing press and the relay position where the mounting table on which the printing sheets are stacked is placed, and the sheet feeding device side of the sheet-fed printing press at the relay position, which is provided on the mounting table. Two parallel rulers, which are arranged so as to regulate the front end position of the printing paper stacked in the vertical direction, and two parallel rulers when the truck device passes, A means for moving the arms relative to each other, two parallel arms arranged at the relay position so as to have a space wider than the width of the truck, and a vertical movement driving means for vertically moving the arms. In the paper feeding device, the up-and-down movement drive means positions the arm at the lowest position when the mounting table on which the printing paper is loaded is placed on the arm, and when the truck device enters the relay position, the arm is placed below the arm. Dolly device advances It is raised to allow a sheet feeder, characterized in that it is controlled so as to lower in order to mount the table loaded with the printing paper on the trolley device when the truck apparatus is stopped at the relay location.

<Operation> The sheet feeding device of the present invention includes two rulers for positioning the sheet and two vertically movable elements extending in a direction orthogonal to the rulers.
Two arms are provided, and the paper loaded on the loading table is lowered onto the two arms that are in a raised state by using a carrier such as a hand lift, and after removing the carrier, rails and the like are placed under this. The trolley device guided by is placed, and then the arm is lowered to place the mounting table on which the printing paper is loaded on the trolley device, and the trolley device is moved so that the printing paper is fed to the paper feeding device. Sent out.

<Examples> The present invention will be described in detail with reference to Examples.

FIG. 1 shows the entire printing machine. The normal printing paper (1) is first prepared in the paper feeding device (2) of the printing machine,
Then, the printing paper (1) is delivered to the paper feeding device (3) by using a truck (4) guided by rails, conveyors, etc., and the printing paper (1) is fed one by one from the paper feeding device (3). After being sent out to the printing device (5) for printing, the printing paper (1) is stacked by the paper discharging device (6).

FIG. 2 shows a paper feeding device, in which (11) is a shaft passed between two columns (12) and (12), and the printing paper (1) is positioned on the shaft (11). Two rulers for (13)
(13) is attached so as to be movable in the left-right direction. Further, two arms (14) (14) extending in a direction perpendicular to the rulers (13) (13) are juxtaposed on the cylinder (15) at appropriate intervals, and the cylinder (15) A pressure device (17) is connected to the pipe via a pipe (16).

The printing paper (1) loaded on the mounting table (18) is carried by a carrier (19) such as a hand lift and is then transferred to the arm (14).
(14) Dropped on. At this time, the arm (14) (1
4) is in a raised state, and the ruler (13) (1
The printing paper (1) is positioned in contact with 3). After this, open the rulers (13) (13) to the left and right, put the truck (4) guided by the rail (20) under the placing table (18), position it at a predetermined position, and then place it in the cylinder. (1
The mounting table (18) is fixed to the upper surface of the dolly device (4) by moving the arm (14) (14) down by operating the armature (5). If a device whose upper part moves freely is attached to the dolly device (4), the position can be set parallel to the ruler. Then, the truck (4) is moved to feed the paper (1) to the paper feeder (3).

The two rulers (13) (13) are moved by a drive means (31) such as a monitor and a pressure device, and stopped at a predetermined position by using a control means (32) such as an encoder and a proximity switch. May be.

<Advantages of the Invention> As described above, according to the present invention, since the print paper placed on the placing table can be placed on the two vertically movable arms which are installed on the left and right sides, There is an excellent effect that anyone can easily operate using such a manual carrier.
