Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a lubricating device for a printing device, and particularly relates to a lubricating device that is easy to manage oil and install.

<Prior Art> The following methods are known as conventional oil supply methods for printing units. In other words, one oil pump is provided for each printing unit for each color, which is divided into multiple units, and an oil pipe is arranged from this oil pump to each printing unit to supply the oil required for the printing unit to the one oil pump. This method uses a pump to supply the water.

<Problems that the invention aims to solve> However, this type of oil supply method requires a large number of pipes, making it complicated, and requires a large-capacity oil pump to pump the oil, resulting in an increase in size. There was a problem. Furthermore, as a means to solve this problem, there is an oil bath method in which an oil bath is provided at the bottom of the frame of each printing unit, and oil is pumped up from this oil bath and supplied with oil. When replacing the oil in use with new oil, the work is difficult and requires a lot of man-hours. There are also problems in that the condition of the oil, especially the degree of dirt, cannot be checked, and furthermore, the deposits that accumulate in the oil bath cannot be removed. As a result, users have not managed the oil adequately, resulting in poor lubrication due to oil failure, including insufficient oil, and in the worst case, seizing of the bearings.

<Means for Solving the Problems> Therefore, in the present invention, the oil supply device is configured as follows. That is, an oil tank equipped with an oil pump for pumping oil, a control valve, and an autopsy mud was constructed so that it was located separately from each unit of the printing press.

<Example> An example of the oil supply device according to the present invention will be described below.

FIG. 1 shows a printing press using the oil supply device of the present invention. The printing press 4 consists of units 6 for each color, and in the figure, four units 6 are lined up. Each of these units 6 has a rotating member called a barrel, which is rotatably supported at both ends thereof, and the oil supply device 2 supplies oil to this rotating support portion.

The oil supply device 2 is installed on each driving side of the unit 6, and is connected to the supporting portion on the opposite side by an oil pipe. The oil supply device 2 is specifically shown in FIGS. 2 and 3. Oil supply device 2 shown in the same figure
The lower part is a box-shaped oil tank 8,
An oil pump 10, a control valve 12, etc. are installed above it. The oil pump 10 is for pumping the oil in the oil tank 8, and the control valve 12 is for adjusting the pressure and flow rate of the pumped oil to a predetermined pressure and flow rate. Further, an oil supply port 14 is provided on the upper surface of the oil tank 8. This supply port 14 is connected to the unit 6 through an oil pipe 16, as shown in FIG. 1, and sends the oil pumped by the oil pump 10 to the unit 6. The oil then returns to the oil tank 8 through the oil pipe 18 through a return port 20 provided on the side of the oil tank 8. Further, an inspection lid 22 made of acrylic resin or the like is provided on the side of the oil tank 8, so that the oil inside can be observed from the outside. An opening/closing type inlet 24 is attached to the upper right side of the oil tank 8 in the figure, from which oil can be injected into the interior, and from which deposits can be easily removed. is provided with a drain port 26 through which the oil inside can be drained.

Therefore, according to the oil supply device 2, since the oil supply device can be installed for each unit 6, it is easy to adapt to changes such as increasing or decreasing the number of units 6, and it is also possible to store oil in the oil tank 8 and release the oil from there. Since the oil is pumped, it is easy to change the oil and inspect the oil before replacing it.
Furthermore, it is easy to remove the deposits that settle in the oil tank 8.

<Effects of the invention> As described above, according to the invention, a separate oil supply device is provided for each unit of the printing press, and this oil supply device is connected to the oil pump, oil tank, and oil tank. Since it is composed of a coroner for oil inspection and a control valve to control the oil flow, it is possible to respond appropriately to changes in the overall configuration of the printing press, such as an increase or decrease in the number of units. There is no need to increase the size of the equipment, inspection of oil contamination is easy, and oil can be easily supplied and discharged from the supply port and discharge port when changing the oil.
