Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is a system that is attached to a large number of printing machines that print on various types of paper, and for sequentially distributing printing paper to be supplied to these printing machines. It is related to the device.

(Prior art) In recent years, various types of printing machines have been developed to perform various types of printing, and they have progressed considerably, and in terms of the printing machines themselves, it has become possible to print at high speed and in large quantities. . however,
In order to enable high-speed, large-volume printing, it is not enough to develop the printing press itself. This is because even if a printing press is capable of high-speed printing, if the printing paper to be printed is not efficiently distributed or supplied to the printing press, the performance of the printing press will depend on the feeding speed of the printing paper. It is.

Furthermore, during actual printing work, there are the following problems. In other words, the sheets of paper that have been cut often stick to each other, and unless they are carefully fanned to create a certain amount of air between each sheet of paper, the paper will not be fed properly and printing efficiency will be affected. This results in a decrease in In order to deal with this, what has traditionally been done is that the operator actually handles the printing paper by hand before printing begins.
This was supplied to the printing press from below. The necessary amount of printing paper must be sequentially supplied as printing progresses, but this work is continuous and requires bending over, making it difficult for the operator. It was very hard work. Moreover, one worker is always required to prepare and supply this printing paper, and a worker is also required to adjust and monitor the printing machine itself, so in the end, the printing machine requires at least two workers. People will be needed.

The development of devices and equipment that takes into account the efficient deployment of printing paper and the reduction of worker labor has not yet been sufficiently developed.
The reality is that the provision of printing paper ultimately relies on human power.

It is something that is raised after acceptance. Further, when the receiving plate of the elevating lift 23 is located at its ascending end, it automatically descends to its original position.

The work area 30 specifically forms a work space, on which the worker (M) stands and works on sorting printing paper (P), and the next part of the paper (P) that has been sorted. This is used for reloading work to the second lift section 40. In the present invention, the workbench 30 constituting this workspace
By installing it between a pair of second lift parts 40 (in FIG. 1, between a pair of second lifts 40 arranged above and below on the left side of the drawing), which will be described later,
This workbench 30 is arranged to face each of the first lifts 20 and the second lifts 40, respectively.
That is, with respect to this workbench 30, each of the first lift portions 20 and the second lift portions 40 in one of the deployment devices 100 are arranged so as to sandwich the corners of the workbench 30. Of course, the same applies to the other deployment device 100.

As shown in FIGS. 1 and 4, the second lift section 40 is provided with a large number of rollers 42 on both the upper and lower edges of the base 41 in the drawing, and between these rollers 42, that is, in the center of the base 41. A descending lift 43 is arranged. The descending lift 43 is driven by a drive device (not shown), and as the printing paper (P) is sequentially stacked on the pallet 45 on the receiving plate,
It descends from the rising end to below each roller 42.

Further, this second lift portion 40 includes a support frame 44f.
A position adjustment device 44 is provided via the. As shown in FIGS. 5 to 7, the position adjustment device 44 includes a pair of vertical substrates 44a and a stopper 44 rotatably provided on each of the vertical substrates 44a.
b, and a screw shaft 44c for adjusting the position of each vertical board 44a. Each vertical board 44a is connected by threading a support block 44e attached to its back surface onto a screw shaft 44c which is appropriately rotated by a handle 44d. Also, this vertical substrate 44
a is movably supported with respect to a support frame 44f by support rollers, guide members, and support blocks 44e provided on its back surface, so that the vertical substrate 44a is perpendicular to the support frame 44f. While supported, it can be moved by the same amount in the left and right directions in FIG. 5, in other words, symmetrically with respect to the center of both. Then, each stopper 44b has a fifth stopper 44b.
The vertical substrate 44a on the left side of the figure is rotatably connected to the left side, and the vertical substrate 44a on the right side of the figure is rotatably connected to the right side.
It is designed to be fixed in a position perpendicular to 4a. This stopper 44b is connected to the vertical substrate 44a.
The printing paper (P) is positioned at right angles to the paper (P). In addition, in Fig. 5,
In order to deploy the left reference printing paper (P), only the stopper 44b on the left side in the figure is fixed at right angles to the vertical substrate 44a, and the stopper 44b on the right side in the figure is fixed at right angles to the vertical substrate 44a.
is left open. Further, in this example, each stopper 44b is formed on one side of both vertical substrates 44a, but only one of the vertical substrates 44a
It may be provided only in

In addition, the threaded shaft 44c has opposite threads cut on the left and right sides of its center, so that each vertical board 44a supported by the support block 44e can be rotated to rotate the threaded shaft 44c in opposite directions. Move an equal distance in the direction.

A second conveyance path 50 is arranged on the right side of the second lift section 40 in FIG. 1 . This second conveyance path 50 has substantially the same configuration as the first conveyance path 10, and is arranged parallel to the first conveyance path 10. That is, this second conveyance path 50 has a base 51 installed parallel to the base 11 of the first conveyance path 10.
It is formed by providing a large number of rollers 52 on this base 51. Further, the terminal end of the second transport path 50 is arranged at a position that substantially coincides with the starting end of the first transport path 10.

Therefore, in the deployment device of the present invention, the first lift section 20,
A conveyance path that is approximately U-shaped after passing through the workbench 30 and the second lift section 40 is connected to the first and second conveyance paths 10 and 5.
Each of them is composed of 0. Therefore, the right side in FIG. 1 of these substantially U-shaped conveyance paths is the starting end and the ending end, respectively.

Further, in each deployment device 100, a first photoelectric switch 60 and a second photoelectric switch 70 are arranged so as to sandwich the first lift section 20 and second lift section 40, respectively, and the first lift section 20 is arranged to sandwich the first lift section 20 and the second lift section 40, respectively. The second lift section 40 is controlled by the photoelectric switch 60, and the second lift section 40 is controlled by a second photoelectric switch 70, respectively. The first photoelectric switch 60 of the first lift section 20 consists of a light receiver and a light emitter, and when the light receiver receives light, it raises the elevating lift 23 of the first lift section 20, and the light receiver emits the light. This is to issue a signal to stop the lifting of the lift 23 when the lift is no longer being received. On the other hand, the second photoelectric switch 70 of the second lift section 40 also consists of a light receiver and a light emitter, and when the light receiver receives light, it stops the downward lift 43 of the second lift section 40, and the light receiver turns off the light. A signal is issued to stop the descending lift 43 when the printing paper (P) is no longer being received (when the printing paper (P) is no longer present).

(Function) The operation of the deployment device according to the present invention configured as described above will be explained, but in order to simplify the explanation, the operation of one deployment device 100 will be explained. That is, for example, in the case of the deployment device 100 shown on the upper side of FIG. 1, the pallet 12 on which printing paper (P) is appropriately placed is first placed on the first conveyance path 10. In this case, if there are multiple types of printing paper (P) used by the printing machine, they are placed one after another according to the order of use. If multiple types of printing paper (P) are sequentially placed on the first conveyance path 10 along with the pallet 12 in this way, even if the next process does not proceed,
Each printing paper (P) can be kept on standby.

Next, by opening the stopper 14, one of the pallets 12 that has been kept on standby is carried onto the first lift section 20 together with the printing paper (P). The operator (M) takes an arbitrary amount of the printing paper (P) carried onto the first lift section 20 and transfers it onto the second lift section 40 while handling it one by one, aligning the edges. . During this work, if the amount of printing paper (P) becomes low and it becomes difficult to pick it up, the first photoelectric switch 60 constantly monitors the amount of printing paper (P) and When the amount decreases, a signal is issued to raise the lifting lift 23, and the lifting lift 23 rises accordingly, so the worker (M) can always work at a constant height. . In addition, since the worker can work in the work space formed at the left end of the center line (l) shown in FIG. It can be easily done along with other work. Note that the operator (M) operates the elevating lift 23 of the first lift section 20 using a hand switch or a foot switch, and the elevating lift 2
3 can be increased as appropriate.

On the second lift section 40 side, the position adjustment device 44 is set as follows. That is, first, the center of the pallet 45 on the second lift section 40 side is positioned in the middle of the vertical substrate 44a. Then, by appropriately rotating the screw shaft 44c, the position of each vertical board 44a is adjusted so that the center of the printing paper (P) to be placed on the pallet 45 coincides with the center of the pallet 45, and the stopper 44b is It is positioned perpendicular to the vertical substrate 44a. If the printing paper (P) is sequentially placed on the second lift section 40 using the position adjustment device 44 set in this way,
The printing paper (P) is placed exactly in the center of the pallet 45 and with its corners aligned. During this work, if the amount of printing paper (P) increases and it becomes difficult to stack the printing paper (P), the second photoelectric switch 70 constantly monitors the amount of printing paper (P) and When the amount of printing paper (P) increases, a signal is issued to lower the descending lift 43 little by little, and in response to this, the descending lift 43 descends little by little, so the operator (M) can check the printing paper (P). You can always work at a constant height. The operator (M) can also use a hand switch or a foot switch to operate the lowering lift 43 of the second lift section 40 and lowering the lowering lift 43 as appropriate.

In this way, the printing paper (P) stacked on the pallet 45 in a state in which the paper sheets (P) are sorted and accurately aligned with the corners thereof are pushed onto the second transport path 50 together with the pallet 45. On this second conveyance path 50, the printing paper (P) placed on this pallet 45 is conveyed toward the printing machine. Note that if there is still printing paper (P) that has been previously deployed on this second transport path 50, the current printing paper (P) remains on the pallet 45 and waits on the second transport path 50. do.

In addition, when the elevating lift 23 of the first lift section 20 reaches its full height, this is sensed by a limit switch (not shown), and the elevating lift 23 automatically descends to its lowering end. On the other hand, if the second lift section 40 of the descending lift 43 has been lowered to its lower end, this is detected by a limit switch (not shown), and the descending lift 43 is automatically raised to its upper end. do.

(Effects of the Invention) Therefore, with the deployment device according to the present invention configured as described above, a large amount of the plural types of printing paper (P) necessary for the printing machine can be deployed in advance. In other words, printing paper (P) can be fed to a printing machine running at high speed without stopping it, and this work can be done simultaneously to multiple printing machines, so printing work can be improved. Efficiency can be further increased. In addition, in this deployment device, since each of the first conveyance path 10 and the second conveyance path 50 has a predetermined distance, the work in the printing machine may proceed beyond schedule, or Even if there is a delay, this can be adequately addressed.

In addition, when the separated printing paper (P) is placed on a printing machine, it is necessary that its edges are neatly aligned. Therefore, the organization work can be done easily.
Moreover, during this deployment work, the worker can do all the work in a standing position without bending down, and without moving around too much on the workbench 30, which is the work space. It is not as tiring as traditional deployment work.

Furthermore, by using printing paper prepared in advance in this way, paper can be fed to the printing machine in a single hour, so there is no need to have a single worker on the printing machine to feed paper. .
In other words, in each printing press, the worker who is monitoring it can directly feed the paper prepared by the deployment device 100 to the printing press in a single hour, so the worker for the printing press can It requires fewer people than a printing press without equipment.

Furthermore, since this deployment device has a relatively simple configuration, it is easy to manufacture, and since the first conveyance path 10 and the second conveyance path 50 are arranged parallel to each other, the inside of the factory can be made relatively compact. It can be summarized as follows.

Moreover, as shown in FIG. 1, in the deployment device according to the present invention, since the pair of deployment devices 100 are arranged symmetrically above and below the center line (l), the left-aligned and right-aligned printing sheets There is the convenience of being able to deploy (P) at the same time.
