Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an apparatus for automatically applying oil to both end surfaces of a steel strip coil and inner peripheral surfaces of holes.

(B) Prior art Oil is applied on both end faces of the steel strip coil immediately after the pickling, cold rolling, skin pass rolling, etc. for rust prevention of the inner peripheral surface of the hole. Conventionally, a worker has applied oil with a hand spray or the like.

However, with such manual work, the amount of applied oil varies,
Inability to apply uniform oil, deterioration of basic unit of rust preventive oil, bad working environment and harm to human body, and long-term use makes the floor slippery due to oil adhesion, thus lowering workplace safety. There were some drawbacks.

(C) Problem to be Solved by the Invention The problem to be solved by the present invention is to improve the working environment, improve the quality of oiling, and prevent rust-preventing oil from being consumed by automating the oiling work of the steel strip coil. Is to improve.

(D) Means for Solving the Problems The oil coating device for a steel strip coil according to the present invention is such that both axial end faces of the plurality of steel strip coils are continuously conveyed while the axial centers of the plurality of steel strip coils are respectively directed in the traveling direction. And a line for simultaneously applying oil to the inner peripheral surface, and a closed chamber which is installed on the line and which opens and closes the opening and closing door and through which the coil passes, and which is arranged above the closed chamber in a direction parallel to the line. And a pair of carriages traveling on the rails, a lifting mechanism hung on each carriage, and a plurality of sprayers that are mounted on the lifting mechanism so as to oppose each other and spray oil onto a plurality of predetermined oil coating areas, respectively. A header having a nozzle, and a height detector mounted on the carriage for detecting the height position of the header,
The above problem is solved by comprising an opening / closing valve connected to each of the nozzles and a device that controls opening / closing of each nozzle based on the size of the coil and the position of the header with respect to the coil.

(E) Example An example of an oil coating device for a steel strip coil according to the present invention will be described with reference to the drawings. FIG. 1 shows an oiling line 2 in which an oiling device 1 of the present invention is installed. In the oil coating line 2, the axial centers 31 of the plurality of steel strip coils 3 are respectively placed on the walking beam conveyor 21 in the traveling direction and continuously conveyed while the coil 3 has both end faces, outer peripheral faces and inner peripheral faces. Apply oil at the same time.

The oil applying device 1 is installed on the oil applying line 2. As shown in FIGS. 2 and 3, the oil coating device 1 is composed of a closed chamber 11, carriages 12a and 12b, lifting mechanisms 13a and 13b, headers 14a and 14b, and a control device 15.

The closed chamber 11 is installed on the oil coating line 2 and has an opening / closing door 11
The steel strip coil 3 passes through 1 in the direction of the arrow. The pair of carts 12a, 12b described above in the closed chamber 11 and the pair of lifting mechanisms 13
a, 13b, a pair of headers 14a, 14b, and a part of the control device 15 are provided. A pair of these elements are provided for simultaneously applying oil to both end surfaces, the outer peripheral surface and the inner peripheral surface of the hole of the steel strip coil 3 fed into the closed chamber 11. Since both have substantially the same configuration, the following description will explain each element of one.

The dolly 12a runs above the inside of the closed chamber 11 on rails 112 arranged on both sides in parallel with the oil coating line 2.

The elevating mechanism 13a is suspended on the carriage 12a. The header 14a is attached to the lifting mechanism 13a and is driven up and down by the mechanism 13a. The header 14a includes a plurality of nozzles 141a.
The nozzle 141a sprays rust preventive oil.

The control device 15 controls opening / closing of each nozzle 141a based on the dimensions of the steel strip coil 3 and the position of the header 14a with respect to the coil 3. The control device 15 is composed of a control device (not shown) and various detectors (in the illustrated example, only the coil end face detector 151a and the height detector 131a of the header 14a are shown). The coil size is input to the control device in advance before applying the coil. The presence and position of coil 3 is a detector
Made by 151a. The position of the header 14a is the lifting mechanism 13a.
This is detected by a height detector 131a such as a tachometer attached to a motor (not shown) or a conventional limit switch. The detection signals from various detectors are sent to the control device,
The opening and closing of the valve attached to each nozzle 141a is controlled to control the oiling range of the nozzle as described below.

As the nozzle on-off valve, a pressure fluid (for example, compressed air) actuation type on-off valve is provided in the vicinity of the nozzle, and the pressure fluid is controlled by the valve stand 16 outside the sealed chamber 11. As a result, the spray on / off response is improved without placing the solenoid valve for opening / closing control in the room, and optimal spray control becomes possible.

Next, the operation of the device of the present invention will be described. The coil 3 automatically carried into the closed chamber 11 shown in FIG. 2 receives coil information from the host computer and starts one-cycle automatic operation. When the coil is stopped at the fixed position, the entrance / exit door 111 is fully closed, and at the same time, the carriages 12a and 12b are moved forward to the fixed position corresponding to the coil width. The carts 12a and 12b are coil end face detectors 151a and 151b.
It is stopped by turning on. After the coil end surface is detected, the headers 14a and 14b descend and start the injection of oil from the nozzles 141a and 141b.

As shown in FIG. 4, the nozzle array has end faces A, B, and C.
And are arranged as D and E only for the inner diameter. Based on the coil information, nozzle selection and spray start / stop are set by the height position detectors 131a and 131b. The oiling area is controlled by the valve stand 16 by controlling the opening and closing of valves (not shown) provided in the immediate vicinity of the nozzles 141a and 141b.

Each nozzle 14 arranged at each position A, B, C, D, E
The oil coating areas which are respectively assigned to 1a and 141b are as shown in FIGS. 4 and 5, for example.

After the oiling is completed, the headers 14a, 14b rise, and then the trucks 12a, 1
2b retreats. Then, the mist collecting fan 112 operates for the set time. After the mist collection is completed, the door 111 on the entrance / exit side is fully opened to carry out and carry in the coil. The exhaust mist is removed by a mist removing / collecting device (not shown) provided at a distant place.

Since the coils are normally intermittently conveyed at a pitch of at least 4 minutes (time for winding into a coil), there is a sufficient time margin.

In the above description, the oiling range of each system is determined in advance based on the coil outer diameter information. However, a coil upper surface height detector may be provided to detect the coil diameter when the header descends, and the oil coating pattern may be set based on this.

(F) Effects According to the present invention, it is possible to improve the working environment, save labor, and improve the rust preventive oil consumption rate (improvement of about 10 g / m ² or more) by automating the oiling operation.
