Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper pre-loading working device for a large-sized printing machine that supplies paper to the large-sized printing machine.

[0002]

[Prior art]

 In a large-sized printing machine, it is necessary to supply a large amount of large paper such as A1. In addition, this large-sized printing machine has a rail attached to the floor of the paper supply port, and the paper feed table on which many papers are placed can be moved freely. Therefore, a large amount of paper can be loaded on this paper feed table. If there is no more paper, feed the paper feed port along the rail to the paper feed port, and then retract the paper feed tray installed at the paper feed port along the rail to the end or halfway, and then load a large amount of paper near this retracted paper feed tray. The carts piled up were carried in, and the papers of the carts were sequentially transferred from the top to the paper feed tray by the workers. After that, the paper feed table on which the paper was placed was moved forward along the rails and sent to the paper supply port of the large-scale printing press to carry out the pre-loading work.

However, when transferring a large amount of paper in a cart that is stacked on an empty paper feed tray, an operator sequentially moves the paper stacked on top of the other paper tray to a lower height paper feed tray. At the beginning, the worker moved the paper from the top to the bottom while bending his waist and legs while holding the paper by the difference in height between the upper part of the cart and the upper part of the paper supply table. . Also, if you move the paper about half way and the top of the paper on the cart and the top of the paper on the paper tray are at the same height, you can move the paper on the cart horizontally and transfer it to the paper tray. You can, but if you move the paper further, the height of the upper part of the paper on the paper tray becomes higher than the height of the upper part of the paper on the cart, and the height will be reversed, so the worker will have a lower back and legs. I had to grasp the paper of the cart with my hand bent and lift it above the top of the paper on the paper tray. Since the weight of paper that an operator holds at one time ranges from 5 kg to 10 kg, when transferring a large amount of large paper such as A1 from the cart to the paper tray, it is difficult to grip the paper and it is heavy. Not only is it time-consuming, but it is also extremely labor-intensive for the workers, and the work of pre-loading the paper takes time and effort.

[0004]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve these problems in the past, reduce the burden on the operator in the paper pre-loading work, and perform the paper pre-loading work without trouble, thus reducing the number of steps. It is to provide a paper pre-loading working device for a large-scale printing machine that can do this.

[0005]

[Means for Solving the Problems]

 The configuration of the present invention that solves such a problem is to install a rail on the floor of the paper supply port of a large-sized printing machine, provide a paper feed table that moves on the rail, and place a large amount of paper on the paper feed table. In a paper pre-loading work device of a large-scale printing machine that feeds along the rail to the paper supply port, the end of the rail or the floor surface in the middle is recessed, and an elevator is provided in the recess, and an upper part of the elevator is installed. An elevating rail that can be connected to a floor rail is provided on the upper surface of the elevating table provided in the above, and the paper feeding table can be moved up and down at the position of the above-mentioned recess. . There are link mechanism, cam mechanism, or a combination mechanism of these link mechanism and cam mechanism, etc. as a mechanism for raising and lowering the lifting platform, and a hydraulic cylinder, an air cylinder or a motor can be used as a power source thereof. .

[0006]

[Action]

 In the present invention, the end of the rail attached to the floor of the paper feed port of the large-scale printing machine or the floor in the middle is recessed, and the elevator installed in this recess is driven to raise and lower the lift table. Now, the elevator rails provided on the top surface of the elevator are connected beforehand to the extension of the floor rails.

When there is no more paper in the paper feed table that has been fed to the paper supply port of the large-sized printing press, the paper feed table is retracted along the rail to the elevating rail of the ascending / descending table, and a large number of paper stacks To the vicinity of the paper feed table, drive the elevator, and raise and lower the paper feed table together with the lift table to raise the paper feed table to the position of the uppermost paper on the cargo carrier or to a position slightly lower than this position. The work vehicle holds the paper on the cart by hand and moves the paper from the cart to the paper feed tray by moving the paper almost horizontally in order from the top. Also, if there is a difference in height between the top surface of the paper of the cart and the top surface of the paper on the paper feed tray due to the transfer of paper, the elevator is driven each time, and the paper feed tray is lowered together with the lift base, and Align the top position of the paper placed on the paper feed table with the same height or a little lower position on the paper top position, and the operator moves the paper of the cart to the paper feed table by moving the paper almost horizontally. Go. By repeating these steps, the operator transfers all the sheets of paper stacked on the cart to the paper tray. After that, drive the elevator to make the lift rail on the top of the lift table the same height as the floor rail, connect the lift rail to the extension of the floor rail, and feed the paper feed tray along the rail to the paper supply port. , Finish the pre-loading work of paper.

[0008] Further, not only when the elevation of the sheet feeding table is raised and lowered each time, the sheet feeding table is raised and lowered to raise the height difference not only when the height difference causes a burden to the operator. May be small. After the paper of the cart has been transferred, the paper tray is moved forward along the rail toward the large-scale printing machine and fed into the paper supply port.

It is explanatory drawing which shows the made state.

In the figure, 1 is a large-sized printing machine, 2 is a paper supply port provided in the large-sized printing machine 1, 3 is the same paper supply port, a pair of rails extending in two directions and installed on the floor, 4 is the same paper supply port 2 is a paper feed table having four rollers 5 provided on the lower surface of the rail 3 which is movable back and forth on the rail 3, 5 is a roller of the paper feed table 4, and 6 is a recess formed by recessing the floor at the end of the rail. A recessed portion, 7 is an elevator mounted in the recessed portion 6, 8 is an elevator that forms the upper part of the elevator 7, 9 is an upper guide provided on the opposite side of the lower surface of the elevator 8, and 10 is the elevator 7. A lower substrate, 11 is a lower guide provided on the opposite side of the upper surface of the substrate 10, 12 is a link that is interposed between the lifting platform 8 and the substrate 10 and connects them, and 13 is provided at one end of the link 12. Roller, 14 is a hydraulic cylinder that drives the elevator 7, and 15 is a lift / stop of the elevator 7. An operation unit for stopping and descending, 16 is a lifting rail mounted on the upper surface of the elevator 7 in an extended state of the rail, 17 is A1 paper supplied to the paper feed table 4, 18 is a cart for carrying the paper 17, 19 is a floor and 20 is an operator.

In this embodiment, as shown in FIG. 1, the floor 19 at the end of a pair of rails 3 attached to the floor 19 of the paper supply port 2 of the large-sized printing press 1 is recessed, and the recess 19 is placed in the recess 6. An elevator 7 having an elevator 8 installed at the top is attached, and an elevator rail 16 that can be connected to the extended state of a pair of rails 3 attached to a floor 19 is provided on the upper surface of the elevator 8 to be fed into the paper supply port 2. Since the sheet feeding table 4 provided with the roller 5 is provided on the rail 3 so as to be movable back and forth, the sheet feeding table 4 can be moved along the rail 3 so as to be movable forward and backward. As shown in FIG. 2, the elevator 7 has a structure in which two links 12 are crossed in an X shape, and a pair of links 12 pivotally attached to an intersection at the center of the links 12 are arranged in parallel. , One end of this pair of links 12 is pivotally attached to one end of the lifting table 8, and the other end provided with the roller 13 is movably attached to the lower guide 11 of the substrate 10 and the other link. One end of 12 is pivotally attached to one side of the substrate 10, and the other end of which the roller 13 is provided is movably attached to the upper guide 9 provided on the lower surface of the lift 8. Similarly, another set of links 12 is attached to the opposite sides, and the pair of links 12 is driven by the hydraulic cylinder 14 to move the lifting table 8 up and down. By driving the hydraulic cylinder 14, the roller 13 of the link 12 moves along the upper guide 9 and the lower guide 11, and the pair of links 12 lifts the lifting platform 8. The hydraulic cylinder 14 is operated by the operation unit 15.

Therefore, when the paper 17 runs out on the paper feed table 4 and the paper 17 of A1 is stacked in multiple stages on the paper feed table 4 by the pre-stacking operation of the paper 17, the paper 17 is fed into the paper supply port 2 of the large-sized printing machine 1. The fed paper stand 4 is moved back along the rail 3 to the position of the lift rail 16 on the upper surface of the lift table 8. A large number of A1 sheets of paper 17 to be fed near the retracted paper tray 4 are stacked in a multi-tiered manner to carry a cart 18 to a position slightly lower than the height of the upper surface of the paper 17 loaded on the cart. The paper feed table 4 is positioned so as to be positioned by the elevator 7, and the worker 20 holds the paper 17 of the cart 18 with both hands and moves the paper 17 to the upper surface of the paper feed table 4 by substantially horizontal movement to change it. As a result of this transfer, the position of the upper surface of the paper 17 stacked on the paper feed table 4 becomes higher than the position of the upper surface of the paper 17 of the cart 18 so that the elevator 7 is driven and the paper on the top of the cart 18 is driven again. The elevator 7 lowers the paper feed tray 4 so that the upper surface of the paper 17 loaded on the paper feed tray 4 is located at a position slightly lower than the height of the position 17 and the operator 20 receives the cargo receiving cart 18 in the same manner as described above. The paper 17 is moved to the upper surface of the paper 17 placed on the paper feed table 4 by substantially horizontal movement. By repeating this, the paper 17 of the cart 18 is transferred to the paper feed table 4.

In this manner, the paper 17 of the cart 18 is moved to the paper feed table 4 by horizontal movement, so that the paper feed table 4 is slightly lower than the upper surface of the paper 17 of the cart 18 by the elevator 7. By raising and lowering, it is not necessary for the worker 20 to move the paper 17 of the cart 18 vertically to the paper feed table 4 while bending the waist up and down, and the worker 20 always moves the paper 17 by horizontal movement. Since it can be transferred to No. 4, the burden on the worker 20 can be lightened, and the transfer can be done quickly, which is a pre-positioning work of paper which also leads to a reduction in man-hours.

[0014]

[Effect of device]

 In the present invention, a part of the floor surface of the rail is recessed, and the elevator installed in this recess can raise and lower the paper feed table together with the lift table. When transferring, if the height of the paper on the top surface of the cart that stacks paper in multiple stages or slightly lower height, align the top position of the empty paper feed tray or the paper loaded on the paper feed tray, Since the worker can move the paper to the paper feed table by moving the paper almost horizontally, it is not necessary for the worker to move the paper of the cart to the paper feed table while bending the legs and waist up and down. Not only will the burden on the operator be greatly reduced, but the paper pre-loading work can be performed without much effort, and the man-hours can be shortened.
