Description

[Detailed description of the invention] [Field of industrial application] The invention consists of a mold body having openings at the upper and lower ends, and a face plate for press mirror surface forming that is attached to the lower end opening of the mold body. The present invention relates to an oil applicator for concrete block formwork, and more particularly to an oil applicator that can evenly apply oil to the inner surface of a formwork body.

[Prior Art] Generally, a formwork body having openings at the upper and lower ends,
When assembling a formwork for a concrete block by interconnecting the face plate for press mirror surface forming attached to the lower end opening, the inner surface of the form body and the surface of the face plate must be It is necessary to apply oil to improve mold release during molding.

By the way, conventionally, as a method of applying oil to the inner surface of the form body, a worker is placed along the conveyance line of the form body and the oil application work is performed manually.

[Problem to be solved by the invention] However, in the conventional oil application method, the inner surface of the roughly cylindrical form body must be manually applied with oil within a predetermined short period of time. There are problems in that it is not easy to apply oil, and that oil cannot be applied uniformly due to unoiled areas, resulting in unstable quality of manufactured concrete blocks.

This idea was created in view of the current situation,
To provide a lubricating device for a formwork for a concrete block that can easily and uniformly apply lubricant to the inner surface of a formwork body without using human power.

[Means for Solving the Problems] The present invention provides, as a means for achieving the above-mentioned object, a lubricating tank that opens upward and has an oil pan at the bottom; a fence that rises from the upper opening edge of the lubricating tank; a formwork transport mechanism that carries a formwork body having openings at the upper and lower ends into and out of the oiling tank and raises and lowers it within the oiling tank; a fence opening/closing mechanism that lowers the upper end position of at least the loading/unloading portion of the formwork body and raises the upper end position when the formwork body is raised and lowered in the oiling tank; an oil nozzle that is installed at a position where the formwork body is raised and lowered and sprays oil onto the inner surface of the formwork body when the formwork body is lowered; The present invention is characterized in that an air nozzle for blowing air onto the inner surface of the main body to remove excess oil is provided.

Further, in the present invention, it is more preferable that at least the loading/unloading portion of the form body of the fence is allowed to swing outward using the lower end as a fulcrum by the fence opening/closing mechanism.

[Operation] In the concrete block formwork lubricating device according to the present invention, the formwork body is carried into the lubricating tank by the formwork transport mechanism and is driven up and down within the lubricating tank. When the form body is lowered, oil is sprayed onto the inner surface of the form body by the oil nozzle, and when the form body is raised, air is sprayed from the air nozzle onto the inner surface of the form body to remove excess oil. Ru. Therefore, it becomes possible to easily and uniformly apply oil to the inner surface of the form body.
After oiling, the formwork body and the formwork transport mechanism transport it out of the oiling tank.

By the way, when the form body is carried in and out of the oil application tank, the upper end position of at least the part of the frame body that is carried in and out of the fence becomes low. Therefore, the formwork can be carried in and out of the oiling tank without having to lift it high, and the ceiling of the factory can be lowered accordingly. On the other hand, when the form body is moved up and down in the oil application tank, the upper end position is raised, so there is no risk of oil scattering to the outside during oil application.

In the present invention, as the fence opening/closing mechanism, at least the loading/unloading part of the formwork body is driven to swing outward using the lower end as a fulcrum, so that the fence can be opened and closed with a simple structure and without taking up space. It becomes possible to open and close.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

Figures 1 and 2 show an example of an oil application device for concrete block formwork according to the present invention. In the figures, reference numeral 1 is an oil application tank, and this oil application tank 1 is a second As shown in the figure, the form body 2, which constitutes the concrete block form together with the press mirror surface forming face plate (not shown), is formed into a rectangular container shape large enough to accommodate, for example, six pieces at the same time. There is.

As shown in FIG. 1, an oil receiver 5 is formed at the bottom of the oil application tank 1 to store oil 4 sprayed and dropped from an oil application nozzle 3, which will be described later.
Furthermore, as shown in FIGS. 1 and 2, a fixed fence 6 , a movable carry-in fence 7 , and a movable carry-out fence 8 are provided at the upper opening edge of the oil tank 1 . The height is substantially increased.

As shown in FIG. 1 for the unloading movable fence 8, each movable fence 7, 8 has its lower end pivotally attached to the upper end of the oil tank 1 via a hinge 9. , 8 on the outside,
Fluid pressure cylinder 10 constituting the fence opening/closing mechanism
are provided for each. Each of these movable fences 7 and 8 is moved approximately outward from the vertical position shown by the solid line in FIGS.
The movable fences 7 and 8 can be opened and closed by 90 degrees, and the upper end positions of the movable fences 7 and 8 can be substantially lowered when the form body 2 is carried in and out of the oiling tank.

As shown in FIGS. 1 and 2, the generally cylindrical form main body 2 with open upper and lower ends is held by a form transport mechanism 11 in units of, for example, six pieces. The formwork main body 2 is carried into the oiling tank 1 from the direction shown by arrow A in FIG. It is about to be removed. In addition, this formwork body 2
are raised and lowered within the oil application tank 1 by the operation of the formwork transport mechanism 11.

As shown in FIG. 2, six oil application nozzles 3 are provided upright at the lifting and lowering positions of each form body 2 in the oil application tank 1. It is now possible to anoint with oil.

As shown in FIG. 1, each of the oil application nozzles 3 includes:
The air nozzle 12 has a hollow shape and has a nozzle hole 12a on its upper circumferential surface, and an oil nozzle 13 that is installed at the upper end of the air nozzle 12 and has a nozzle hole 13a on its circumferential surface.
It is connected to a pressure air source 15 via an air pipe 14, and the oil nozzle 13 is connected to the air nozzle 1.
It is connected to a hydraulic power source 17 via an oil pipe 16 passing through the interior of the hydraulic pressure source 17 . And the oil nozzle 13 is
The oil 4 is sprayed onto the inner surface of the form body 2 only when the form body 2 is lowered, and the air nozzle 12 sprays air 18 onto the inner surface of the form body 2 only when the form body 2 is raised. It is designed to remove excess oil 4 by spraying it.

Next, the effects after this embodiment will be explained.

By demolding the concrete block, the formwork main body 2 separated from the press mirror surface forming face plate (attached to the lower end opening of the formwork main body 2) is transferred by the formwork conveyance mechanism 11 into six pieces as one unit. held,
It is carried into the oil application tank 1 from the direction shown by arrow A in FIG.

By the way, prior to this carrying-in, both movable fences 7 and 8 are opened outward almost simultaneously by the contraction operation of the fluid pressure cylinder 10, and in this state, the form body 2 is carried in. Therefore, it is not necessary to lift the formwork main body 2 high by the formwork transport mechanism 11, and the structure of the formwork transport mechanism 11 can be simplified accordingly, and the ceiling of the factory can be lowered.

Once the form body 2 has been carried into the oiling tank 1, both movable fences 7 and 8 are connected to the hydraulic cylinder 10.
is returned to the vertical position almost simultaneously. As a result, the upper end positions of both the movable fences 7 and 8 are the same as the upper end position of the fixed fence 6, and there is no fear that the oil 4 will scatter outside the oil application tank 1 during oil application, which will be described later.

Next, the six formwork bodies 2 are transferred to the formwork transport mechanism 1
1 starts to descend simultaneously within the oil application tank 1. Then, oil 4 is sprayed from the oil nozzle 13 of each oil application nozzle 3 and applied to the inner surface of each form body 2.

When each formwork main body 2 descends to the bottom dead center, the formwork conveyance mechanism 11 is operated and the formwork bodies 2 simultaneously begin to rise within the oil application tank 1 . Then, the spraying of the oil 4 from the oil nozzle 13 is stopped, and the air 18 is sprayed from the air nozzle 12 onto the inner surface of each mold body 2, so that the excess oil 4 is removed. The oil 4 that has been removed and dropped is stored in the oil receiver 5 and sent to the hydraulic power source 17 via a filter (not shown) for circulation.

When each form body 2 rises to the top dead center, the blowing of air 18 from the air nozzle 12 is stopped, and both movable fences 7 and 8 open outward almost simultaneously due to the contraction operation of the fluid pressure cylinder 10. After that, the formwork main body 2 is transferred to the formwork conveyance mechanism 11.
As a result of the operation, the mold is carried out in the direction shown by arrow B in FIG. 2 and transported to a mold assembly position (not shown).

Both movable fences 7 and 8 opened to the outside are returned to the vertical position by the extension operation of the hydraulic cylinder 10 after the formwork body 2 is carried out, or are kept open and moved to the next formwork body 2. Waiting for the delivery.

Therefore, the work of applying oil to the inner surface of the formwork body 2 is
Since this is done automatically, the entire inner surface of the form body 2 can be reliably coated with oil, and since the excess oil 4 is removed after the oil is coated, the oil can be coated uniformly.

In addition, although the case where six formwork bodies 2 were handled as one unit was explained in the said Example, there is no restriction|limiting with respect to the number of formwork bodies 2.

Further, in the above embodiment, the air nozzle 12 and the oil nozzle 13 are integrated, but as long as the form body 2 is in the vertical position, the nozzles 12 and 13 may have separate structures. good.

Further, in the embodiment, both movable fences 7, 8
Although we have explained the structure that opens outward, for example, it moves up and down along the outer surface of the oil tank 1, etc.
Other structures may also be used. Furthermore, it is not necessary to open and close both movable fences 7 and 8 at the same time when the form body 2 is carried in and out, and the movable fence 7 on the carry-in side does not need to be opened and closed at the same time when carrying in and out
When carrying out, only the moving fence 8 on the carrying out side opens and closes.
It may be configured such that only the opening and closing portions are opened and closed.

Further, the formwork main body 2 is not limited to the structure shown in FIG. 1, but can be applied to formwork main bodies of any shape and structure as long as they are cylindrical with open upper and lower ends.

[Effects of the invention] As explained above, the present invention applies oil to the inner surface of the formwork body when it descends in the oiling tank, and also removes excess oil when the formwork body rises within the oiling tank. Since the oil is removed using air, the inner surface of the formwork body can be easily and uniformly coated with oil without using any human power.

Furthermore, when carrying the form body into and out of the oil application tank, the upper end position of at least the part of the fence that carries in and out of the form body is lowered, so that the form body can be carried in and out without having to lift it high.

At this time, the fence opening/closing mechanism allows at least the loading/unloading part of the formwork body to swing outward using its lower end as a fulcrum, so that the fence can be opened/closed with a simple structure and without taking up space. be able to.
