Description

TECHNICAL FIELD The present invention relates to a vertical moving base that is linearly moved in a substantially vertical direction while being guided by a slide rail, and more particularly to sliding between the vertical moving base and the slide rail. The present invention relates to a device for recovering the lubricating oil supplied to the section.

2. Description of the Related Art A vertical moving stand slidably engaged with a substantially vertical slide rail and linearly moved in a substantially vertical direction while being guided by the slide rail is used in various automatic processing machines and assembling devices. It is used. Some of the slide rails are linearly moved in a substantially horizontal direction while being supported by a base. Lubricating oil is generally supplied to the sliding portion between the vertical moving table and the slide rail so as to raise and lower the vertical moving table smoothly and stably.

Problems to be Solved by the Invention By the way, since the lubricating oil supplied to the sliding portion was made to flow down along the slide rail and dropped from the lower end of the slide rail as it was, the surrounding environment was It was not preferable because it became dirty with lubricating oil. This is because it is usually impossible to provide an oil receiver or the like at the lower end portion of the slide rail because the lower end portion of the vertical moving table is normally lowered to a position where it projects downward from the lower end portion of the slide rail. In particular, when the slide rail is supported by the base and can be linearly moved in a substantially horizontal direction, the drop position of the lubricating oil is also moved as the slide rail is moved. The recovery of the lubricating oil becomes even more difficult.

The present invention has been made in view of the above circumstances, and an object of the present invention is to collect the lubricating oil supplied to the sliding portion of the vertical moving table.

Means for Solving the Problem In order to achieve the above object, the lower end surface of the slide rail is inclined to allow the lubricating oil to flow down to the side opposite to the vertical moving table, and the lubricating oil is provided so as not to interfere with the vertical moving table. The present invention is directed to a vertical moving table which is slidably engaged with a substantially vertical slide rail and linearly moved in a substantially vertical direction while being guided by the slide rail. A device for collecting the lubricating oil supplied to the sliding portion between the vertical moving table and the slide rail, wherein the lower end surface of the slide rail faces the side opposite to the vertical moving table side of the slide rail. Has a sloping surface sloping downward in accordance with the above, and the receiving trough into which the lubricating oil flowing down along the sloping surface is made to flow is perpendicular to the lowermost part of the bottom of the sloping surface. It is characterized in that it is arranged so as not to interfere with the moving table.

Here, when the slide rail is linearly moved in a substantially horizontal direction while being supported by the base, the receiving gutter is fixed to the lower end portion of the slide rail and the outflow provided in the receiving gutter. A second receiving trough into which lubricating oil flowing down from the section is introduced regardless of the movement state of the slide rail is fixed to the base, and the second receiving trough is connected to a lubricating oil recovery container using a hose or the like. It is desirable to pour. It is also possible to directly connect a hose or the like to the outflow portion of the receiving gutter fixedly provided at the lower end of the slide rail to recover the lubricating oil.

Further, the receiving trough does not necessarily need to be attached to the slide rail, and when the lowermost part of the inclined surface on which the lubricating oil flows down is parallel to the movement path of the slide rail, the state of being close to the lowermost part of the inclined surface. It is also possible to fix it to a base or the like. In that case, the slide rail is fixed in parallel with the movement path of the slide rail so that the lubricating oil can flow from the lower end surface thereof regardless of the movement state of the slide rail.

When the slide rail is fixedly positioned, the receiving gutter may be fixed to the lower end of the slide rail or another member for fixing the position.

With this configuration, the lubricating oil supplied to the sliding portion between the vertical moving table and the slide rail is allowed to flow down along the slide rail and then is provided on the lower end surface of the slide rail. The slanted surface is made to flow down to the side opposite to the vertical moving table, and further, it is made to flow into a receiving trough arranged below the lowermost part of the inclined surface so as not to interfere with the vertical moving table.
Therefore, by collecting it in a collecting container or the like using a hose or a second receiving gutter, it is possible to prevent the lubricating oil supplied to the sliding portion from damaging the surrounding environment.

In addition, when the slide rail is linearly moved in a substantially horizontal direction while being supported by the base, the receiving gutter is fixed to the slide rail and a second receiving gutter is provided on the base to receive the receiving gutter. If the lubricating oil that has flowed into the second trough is allowed to further flow into the second trough, the hose, etc. will move as the slide rail moves, as in the case of connecting the hose to the trough and collecting the lubricating oil. There is no inconvenience such as the movement of the item, catching it on other members or pulling the hose.

The back plate 44 is fixed. A lubricating oil supply path 46 is formed in the vertical moving table 34 and the back plate 44 so that the lubricating oil is supplied to the sliding portion with the slide rail 42. The table 34 is smoothly and stably reciprocated in the vertical direction while being guided by the slide rail 42. In addition, the vertical moving table 34
Is lowered to a position where the lower end thereof projects downward from the lower end of the slide rail 42.

The lubricating oil flows down the side surfaces of the slide rails 42 and reaches the lower ends thereof, but the lower end surfaces 48 of the pair of slide rails 42 are also shown in FIG. As is apparent, on the opposite side of the slide rail 42 from the vertical moving table 34 side, there are inclined surfaces that incline downward toward the rear side, which is the right side in FIG. 2, and incline downward toward the inside from the left and right. Has been done. Therefore, the lubricating oil that has reached the lower end portion of the slide rail 42 travels along the lower end surface 48 thereof and flows down toward the inside of the rear portion.

Further, at the lower end rear part of the slide rail 42 which is the lowermost part of the inclination of the lower end face 48, a receiving gutter 50 is attached across the pair of left and right slide rails 42, and the lubrication flowing down along the lower end face 48 is carried out. Oil is caused to flow into the receiving trough 50.
The groove width of the receiving trough 50 is relatively narrow, and is arranged so as not to interfere with the vertical moving table 34 that is lowered below the lower end of the slide rail 42. Further, the receiving gutter 50 is provided in a slightly downward right direction in the left-right direction that is the longitudinal direction thereof, and an outflow pipe 52 that opens downward as an outflow portion is fixedly provided at the bottom end of the right end thereof.
The lubricating oil that has flowed into the receiving trough 50 is made to flow downward from the outflow pipe 52 and flow into the second receiving trough 54.

The second receiving trough 54 is attached to the base 10 in parallel with the moving path of the horizontal moving table 14 in plan view, and lubricates down the outflow pipe 52 regardless of the moving state of the horizontal moving table 14. It has a length that allows oil to flow in. Further, the second receiving gutter 54 is arranged slightly downward to the right in the left-right direction, and a connecting port 56 is fixedly attached to the bottom portion of the right end thereof and a hose 58 is connected thereto. The hose 58 is connected to a lubricating oil recovery container arranged below the base 10 and has a second receiving gutter 54.
The lubricating oil that has flowed in is collected in the lubricating oil recovery container through the hose 58.

As described above, in the present embodiment, the lubricating oil supplied to the sliding portion between the horizontal moving table 14 and the slide rail 22 receives the oil receivers 28, 30.
The lubricating oil supplied to the sliding portion between the vertical moving table 34 and the slide rail 42 is collected through the receiving trough 50, the second receiving trough 54, and the hose 58 while being collected in the collecting container through Since the oil is collected in the container, the lubricating oil does not damage the surrounding environment.

The receiving trough 50 is provided on the slide rail 42, and the lubricating oil flowing into the receiving trough 50 flows into the second receiving trough 54 provided on the base 10 and is collected. Therefore, compared with the case where the hose 58 is directly connected to the outflow pipe 52 of the receiving gutter 50 to collect the lubricating oil,
There is no inconvenience that the hose 58 is caught on another member or the hose 58 is pulled when the 14 is moved, and the movement of the horizontal moving base 14 is not hindered.

Although one embodiment of the present invention has been described in detail with reference to the drawings, the present invention can be implemented in other modes.

For example, in the above-described embodiment, the lower end surfaces 48 of the pair of slide rails 42 are inclined surfaces that are inclined downward toward the rear inside, but if the conditions permit, the length and width dimensions of the receiving trough 50 are increased. Therefore, it does not matter if the inclined surface is inclined downward toward the rear side. Note that the rear side means the side opposite to the vertical moving table 34 side, and does not necessarily mean the rear side in the entire apparatus.

Further, in the above-described embodiment, the lubricating oil is made to flow from the receiving gutter 50 to the second receiving gutter 54, but a hose 58 is connected to the outflow pipe 52 of the receiving gutter 50 to directly collect it in a recovery container. It is also possible.

Further, in the above-described embodiment, since the rear end edge of the slide rail 42 is parallel to the movement path of the slide rail 42, the groove width dimension of the second receiving trough 54 is increased within the range where it does not interfere with the vertical moving table 34. By setting the length according to the moving stroke of the horizontal moving base 14, the lubricating oil flows directly into the second receiving trough 54 from the lower end surface 48 of the slide rail 42 without providing the receiving trough 50. It is also possible to do so. In that case, the second trough 54 corresponds to the trough. The second receiving trough 54 is not necessarily the base 10
It is not necessary to mount it on the other side, and it is possible to provide it on another member for fixing the position.

Further, the rear end edge of the slide rail 42 does not necessarily have to be parallel to the movement path of the slide rail 42. For example, in FIG. 1, the vertical movement table 34 is arranged downward with respect to the horizontal movement table 14. However, when this is arranged rightward or leftward, the rear end edge of the side opposite to the vertical moving table 34 side is the vertical direction in FIG. 1, and the receiving gutter 50 is arranged along the vertical direction. The Rukoto. In this case,
As described above, since the second receiving trough 54 cannot be used as it is as the receiving trough, it is necessary to attach the receiving trough 50 to the lower end portion of the slide rail 42.

Further, in the above-described embodiment, the lower end of the vertical moving table 34 is lowered to the position where it projects downward from the lower end of the slide rail 42, but the lower end of the vertical moving table 34 is lowered from the lower end of the slide rail 42. The present invention can be applied to the case where no protrusion is made. In that case, since the receiving gutter 50 does not interfere with the vertical moving table 34, the receiving gutter 50
There are no restrictions on the width dimension of the.

Further, in the above-described embodiment, the vertical moving table 34 is guided by the pair of slide rails 42, but the vertical moving table 34 is guided by one slide rail such as one having a T-shaped cross section. You can also

Further, in the above-described embodiment, the horizontal moving base 14 also has the slide rail 22.
Although the guide means and the drive means of the horizontal moving table 14 can be changed as appropriate. It is possible to change the driving means of the vertical moving table 34.

Further, although the base 10 is arranged in a fixed position in the above-mentioned embodiment, it is also possible to move the base 10 in the vertical direction in FIG. 1, for example.

Further, in the above embodiment, the slide rail 42 for guiding the vertical moving table 34 is provided on the horizontal moving table 14 so as to be moved in a substantially horizontal direction. Even if it is provided on a fixed member,
The present invention can be applied similarly.

Although not illustrated one by one, the present invention can be implemented in various modified and improved modes based on the knowledge of those skilled in the art.
