Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil application device for a ground round steel bar ground by a coreless grinder or the like.

With the exception of stainless steel products, the entire surface of ground round steel bars as described above must be coated with oil to prevent rust after inspection and before packaging.

Conventionally, such application work involves inserting multiple round steel bars into multiple nylon slings, hanging the slings by hooking them to the claws of a forklift, and applying oil to the round steel bars by applying oil. It was applied by brushing and then sliding the round steel bars together by moving the claws of a forklift up and down.

However, such work requires multiple workers, is inefficient, does not apply uniformly, stains the workplace floor, and wastes oil.

This invention eliminates the drawbacks of the conventional manual oiling work as described above, achieves efficient and uniform oiling by a small number of workers, does not pollute the workplace, and eliminates oil. The object of the present invention is to provide a lubricating device that does not waste any oil.

In order to achieve the above-mentioned object, the present invention includes a coating roller and a wiping roller that are rotatably installed in parallel in the upper opening of an oil tank, and a first drive mechanism that rotates these rollers. A transfer tool whose upper surface slopes downward from the application roller side toward the wiping roller side is installed between both rollers so that it can move up and down, and a second drive mechanism that moves this transfer tool up and down is provided to move the transfer tool up and down. An oil supply nozzle is installed above, an inclined plate for supplying round steel bars is provided in front of the application roller, and an inclined plate for discharging round steel bars is provided behind the wiping roller. That is.

The embodiment shown in the drawings will be described.

Reference numeral 1 denotes an oil tank, which is attached to a machine base 10, and has an application roller 2 and a wiping roller 3 rotatably installed in parallel at its upper opening. A pair of sprockets 5, 6 are attached to one end of the shaft 4 of these rollers 2, 3 protruding outside the oil tank 1 (Fig. 6), and chains 7, 6 are connected between the adjacent sprockets facing each other.
8 is suspended, and the sprocket 5' at the end is connected by a chain 11 to a motor 9 attached to the machine base.

In this embodiment, the application rollers 2 are arranged in two rows, the wiping rollers 3 are arranged in four rows (FIG. 2), and each roller 2, 3 has a plurality of rollers arranged alternately on each shaft 4. It consists of a unit roller, the surface of which is wrapped with a fibrous material such as felt. However, if necessary, each row of rollers may have one roller, and the number of unit rollers may also be one.

A plate-shaped transfer tool 12 is provided in the space on both sides of each unit roller.
is arranged (FIGS. 3 and 6), and the upper surface of this transfer tool 12 has a hook shape that slopes downward from the application roller 2 side to the wiping roller 3 side, and its lower end is attached to the frame 13. It is being The frame 13 is attached at its four corners to a vertically movable rod 14, and the upper end of this vertically movable rod 14 is pivotally connected to the lower end of a lever 15. The upper end of this lever 15 is fixed to rotating shafts 17, 17' which are horizontally rotatable on the machine frame 10, and the upper end of the lever 24 fixed at its lower end is fixed to the rotating shafts 17, 17' horizontally. Connecting rod 16
It is pivotally connected to both ends of the (Figure 4). This rotation axis 1
7' is swingable via a lever 19 by a cylinder 18 installed on the machine frame 10. 20
A guide rod is installed in the oil tank 1 and is slid into a vertical hole provided in the frame 13.

An oil supply nozzle 21 is arranged above the application roller 2, and antirust oil in the oil tank 1 is circulated and supplied to this nozzle 21 by a pump (not shown).
Further, an inclined plate 22 for supplying round steel bars is provided in front of the wiping roller 3, and an inclined plate 23 for discharging round steel bars is provided behind the wiping roller 3.

In front of the inclined plate 22, there is provided an inclined stock plate 26 to which round steel bars inspected by an inspection device (not shown) are sent in parallel. A transfer member 27 is provided for transferring a predetermined number of steel sheets from the stock plate 26 to the inclined plate 22, and furthermore, in the middle of the inclined plate 22, the round steel bars transferred to the inclined plate 22 by the lifter 27 are arranged and placed on a coating roller. An alignment member 28 to be delivered to the second member 2 is installed so as to be retractable by a cylinder 29.

The transfer member 27 is shown in detail in FIGS. 7 and 8, and this transfer member 27 moves up and down in the gap provided between the stock plate 26 and the inclined plate 22, and is moved up and down by the machine base 33. It has a supported transfer tool 31, the upper surface of this transfer tool 31 is inclined in substantially the same way as the upper surfaces of both plates 22, 26, and the operating rod 32 of this transfer tool 31
The lower end of the lever 35 is pivotally connected to the other end of a lever 35 whose one end is fixed to a rotating shaft 34 rotatably supported by the machine base 33, and the rotating shaft 34 operates a cylinder 36 installed on the machine base 33. One end of the lever 37 is pivotally connected to the shaft, and the other end of the lever 37 is fixed.

The alignment member 28 is configured as shown in FIG. 9, and includes an alignment plate 40 that swings vertically through slits formed in the inclined plate 22 at predetermined intervals in the lateral direction. 40 has a base with an inclined plate 22
The rotary shaft 41 is rotatably supported on the back surface of the inclined plate 22, and the rotary shaft 41 is swung via a lever 43 by an operating rod of a cylinder 42 fixed on the back surface of the inclined plate 22. ing.

The state of use of the above-mentioned item will be explained.

The round steel bars a that have been visually inspected by an inspection device (not shown) travel along the stock plate 26 in rows, reach the lifter 27, and are placed on the transfer tool 31 as shown in FIG. Here, the cylinder 36 is actuated to move the transfer tool 31 upward in the direction of the arrow, and transfer the round steel bar a onto the inclined plate 22 at its upper limit. The round steel bars roll on the inclined plate 22, come into contact with the alignment plate 40, are aligned, and then stopped. Here, if there is no round bar steel in the applicator roller 2, a control device (not shown) will control the cylinder 4.
2 is activated, the alignment plate 40 is retracted from the inclined plate 22, and the round steel bar is rolled and supplied toward the application roller 2.

On the other hand, in the oil application device, the motor 9 continuously rotates the rollers 2 and 3, and the oil supply nozzle 21 supplies oil to the application roller 2.
The transfer tool 12 is placed between the rollers 2 and 3 and is moved up and down by the vertical movement of the vertical movement rod 14 due to the operation of the cylinder 18.

Therefore, the round steel bar fed onto the applicator roller 2 as described above is coated with oil while rolling on the surface of the applicator roller 2, and is moved onto the transfer tool 12, which has a so-called walking beam effect. The oil is sequentially transferred to the next roller 2 or 3, and by rolling on the wiping roller 3, the excess portion of the oil applied by the applicator roller 2 is wiped off. It is discharged via the plate 23 toward a packaging device (not shown).

The present invention is as described above, and a coating roller arranged on an oil tank and rotated by a drive device is supplied with oil by an oil supply nozzle, and a round steel bar is sequentially supplied onto the coating roller by an inclined supply plate. After the oil is applied by the rotation, the excess oil is wiped off by the adjacent wiping roller using the transfer tool, and then discharged by the inclined discharge plate, so the oil can be applied efficiently without the need for extra workers during that time. Since the oil always drips into the oil tank, it does not stain the floor of the workplace, and also has the effect of not wasting oil.
