Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a continuous firing device in a tray pusher type firing furnace, which performs quantitative input of raw materials and removal of heated materials without manual intervention.

[Conventional technology]

For example, when heat treating powdered materials such as magnetic materials, a tray pusher type continuous firing furnace 10 as shown in FIG. 7 is usually used.

Trays 2 are arranged in one or more rows on a conveyor provided on a conveyor table, and a heat-resistant cylindrical frame 3 is placed thereon. And inside this frame 3,
In the figure, at position A, a fixed amount of heated material (il-resistant material, etc.)
The inlet bushing 1 is charged from the inlet side 11a of the furnace body 11.
When the container 3 is inserted into the furnace body 11 by the container 2a, the container 3 is conveyed intermittently and comes out from the outlet side 11b of the furnace body 11 after a predetermined period of time. The object 9 to be heated inside the frame that has come out is transferred on the conveyor by the outlet pusher 12b, and the object 9 to be heated is taken out from the frame 3 at position B (FIG. 7). Removal is performed manually by a worker.

That is, as shown in FIG. 8, first the frame 3 is placed on the tray 2.
Then remove the heated object 9 on the tray 2 using a spoon-shaped metal fitting (not shown).
((C) in the same figure) is scooped up and placed in a collection container. Next, the process of returning the frame 3 to the original tray 2 is repeated.

[Problem to be solved by the invention]

However, with the above-mentioned conventional equipment, it is necessary to manually weigh the raw material weighing around 10 kg, put it into a container, and level the surface of the raw material with a brush repeatedly, or lift the object to be heated. There was a problem in that workability and productivity were extremely poor because it required a great deal of labor and time to transfer and transfer.

This invention was made in view of these conventional problems, and aims to solve the above problems by providing a raw material supply device that automatically weighs and inputs a raw material and a heated material discharge device. There is.

[Problem to be solved by the invention]

In order to achieve the above-mentioned object, the present invention uses a Traibunsha type continuous firing furnace to measure and charge raw materials into a container consisting of a tray and a cylindrical frame placed on the tray, and to clean the surface of the raw materials. a raw material supply device having a flattening means;
Continuous firing comprising a frame gripping and lifting device for taking out the heated material coming out of the firing furnace body from the container, and a tray tilting device for gripping and tilting the tray to discharge the heated material on the tray. The frame gripping/elevating device is equipped with a cleaning means for cleaning the inner surface of the frame, and a cleaning means is provided near the tray tilting device to clean the upper surface of the tray when the tray is brought into an upright state by the tray tilting device. It is desirable to provide cleaning means for cleaning.

[Effect]

This invention uses a tray pusher type continuous firing apparatus having the above-mentioned configuration, so that the containers containing the materials to be heated that come out of the firing furnace body after firing are placed on a conveyor outside the furnace, for example, in two rows parallel to each other. In this state, it is pushed by the button to the heated object removal position.

Next, when the container reaches the collection position, the frame is first lifted by the frame grip lifting device, and then the tray on which the heated object is placed is tilted approximately 90 degrees from a horizontal state to an upright state by the tray tilting device, and the heated object is lifted up by the tray tilting device. Objects slide into collection containers. Subsequently, the deposits on the tray surface are removed by cleaning means such as a rotating brush that protrudes from the upright tray.

On the other hand, the frame, which remains lifted, is cleaned of deposits during the firing process, for example, by a cleaning means such as a rotating brush that circulates around the inner surface of the frame. The empty container returned to its original state is then transported to the raw material supply position.

Here, the raw material is measured and introduced by the raw material supply device, the surface of the raw material is leveled, and the raw material is conveyed to the inlet side of the furnace main body, and is inserted into the furnace main body by a pusher.

As described above, during the firing operation, the material to be heated is efficiently processed mechanically without relying on human hands.

grip and rise. The gripping operation at this time is performed by driving the arm opening/closing cylinder 51.

Further, the frame gripping/elevating device 5 has a built-in rotary brush 21 that can rotate, raise and lower, and move from side to side in order to clean the inner surface of the frame 3.

The tray tilting device 6 moves the tilting table 22 provided on the base 23 from a horizontal position via a shaft 61 using a fluid pressure cylinder or the like (not shown).
The heated object 9 on the tray 2 is placed in an upright position in the collection container 6.
2 and further fall onto the delivery conveyor 8. 63 is the tilting table 2 that has come to the heated material discharge position
This is a latching tool for temporarily latching the tray 2 on the tray 2, and is controlled to be hooked and detached.

Reference numeral 7 denotes a rotating brush serving as a tray cleaning means, which is provided so as to be movable toward the tray 2 in the direction of the arrow.

Next, the operation will be explained.

Container 3 containing the heated material coming out of the furnace body 11 after firing
are pushed onto the conveyor 1 outside the furnace by a pusher (similar to the conventional example) in two rows in parallel in this example,
Furthermore, it is loaded from the transport conveyor 1 onto the lateral conveyor 30,
They are horizontally fed in a line and transferred to a collection conveyor 31, from where the containers consisting of the tray 2 and the frame 3 are bundled one by one and brought to the heated object collection position. Here, the frame 3 of the container is first lifted by the lowered frame grip lifting device 5, and then the tray 2 on which the object to be heated (fired object) 9 is placed is tilted to an almost upright state by the tray tilting device 6. As a result, it slides down into the collection container 62 and is delivered by the delivery conveyor 8. On the other hand, the frame 3, which is still lifted, has its inner surface removed by the rotary brush device 21 of the frame grip lifting bag WL5 to remove deposits from the firing process. Similarly, the rotary brush 7, which is a tray cleaning means, is protruded from the tray 2 which is in an upright state, and the deposits on the upper surface of the tray 2 are cleaned. Here, the deposits removed from the frame 3 are swept into the tray 25 of the tray tilting device 6, and fall into the cleaning powder storage box 24 when the device 6 is in a horizontal state. (See Figures 4 and 5).

When the cleaning of the frame 3 and the tray 2 is completed, the frame gripping lifting device 5 descends onto the tray 2 which is in a horizontal state, and the frame 3 is placed on the tray 2 to form a container. This empty container is sent by the conveyor 32 directly below the weighing hopper 15 of the raw material supply device 4, and a certain amount of the raw material weighed by the weigher 26 is cut into the empty container 3 by the gate valve 16b and introduced. Next, the surface of the raw material is leveled by a leveling tool 19 attached to the lower part of the drive device 18 that rotates and revolves at an adjacent position (Fig. 2).After being smoothed, the container 3 containing the raw material is
As shown in the figure, it is transported again to the furnace main body entry side 11a by the transport conveyor 1, and inserted into the firing furnace main body 11 by a pusher (not shown).

During the above-described firing operation, the object to be heated is efficiently processed mechanically without relying on human hands.
