Description

[Detailed description of the invention] (Field of industrial application) The present invention is a rotating body that rotates around an axis while holding an object to be cleaned, such as a grilled meat plate or metal tableware, in a holding frame provided on a rotating body. This invention relates to a cleaning device that shoots shot material from a shot machine toward the body.

(Prior Art) In this type of conventional cleaning device, the object to be cleaned is held in a substantially fixed state within the holding frame of the rotating body, and the object to be cleaned moves only in the direction of rotation of the rotating body together with the rotating body. It is structured as follows.

(Problem to be solved by the invention) In the above conventional example, the object to be cleaned does not move in the axial direction of the rotating body with respect to the shot material shot by the shot machine, so the object to be cleaned held within the holding frame There is a problem in that shot unevenness occurs at the center and on both sides of the object to be cleaned in the axial direction.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a rotating body that rotates around a horizontal axis while holding an object to be cleaned within a holding frame provided on the rotating body. In a cleaning device that shoots shot material from a shot machine toward It is characterized in that the object to be cleaned is held within the holding frame so as to be movable between both ends.

(Function) According to the above configuration, when the holding frame is located closer to the shot machine than the axis of the rotating body, a difference in height is created between both ends of the holding frame in the axial direction, so that the holding frame can move the shot across the axis of the rotating body. As the height of both ends of the holding frame is reversed when the holding frame is located on the opposite side of the machine, the object to be cleaned, which is held within the holding frame so as to be movable between both ends of the holding frame, is The rotating body is moved together with the rotating body in the rotating direction of the rotating body while being held within the holding frame from the above-mentioned opposite position, and during the movement, the rotating body is moved between both ends of the holding frame along the holding frame. It is moved in the axial direction. The object to be cleaned, which is moved in the rotational direction of the rotating body from the opposite position to the shot machine side position, is moved in the opposite direction in the axial direction of the rotating body as the height difference between both ends of the holding frame is reversed again. I am made to do so. In this way, the object to be cleaned moves in the rotational direction of the rotating body as the rotating body rotates, and also repeatedly moves back and forth in the axial direction of the rotating body, so that the central part of the object to be cleaned and the It is possible to prevent shot unevenness from occurring on both sides of the axis.

(Example) Hereinafter, a first example in which the present invention is applied to a cleaning device used for cleaning iron plates for grilled meat will be described with reference to FIGS. 1 to 3.

In the cleaning apparatus shown in FIG. 2, a rotating frame body (rotating body) 3 that holds and rotates a grilled meat iron plate (object to be cleaned) 2 is horizontally installed approximately in the center of a cleaning chamber 1, and a side wall of the cleaning chamber 1 It is supported by a shaft. As shown in FIG. 2, the rotating frame 3 is made of coarse wire mesh and has a triangular prism as its rotation axis 3a.
It is formed into a twisted shape. The holding frame 4 that holds the grilled meat iron plate 2 is formed into a long bag-like shape approximately along the horizontal axis 3a of the rotating frame 3 by overlapping coarse wire mesh.
As the holding frame 4 is twisted around the axis 3a of the rotating frame 3, the holding frame 4 located on the side of the axis 3a shown in FIG.
The left end 4a of the holding frame 4 is high and the right end 4b of the holding frame 4 is low. In addition, wide rubber plates 5 are implanted at the ridgeline portions of the rotating frame 3 so as to protrude in the radial direction of the rotating frame 3. On the other hand, a circumferential surface 7 whose center line is the axis 3a of the rotary frame 3 is formed at a position on the bottom plate 6 to receive pressure from the rubber plate 5 as the rotary frame 3 rotates.

A shot machine 8 is attached to the outside of the side wall of the cleaning chamber 1, and shot material 9 is inserted through an opening provided in the side wall.
is provided so as to be shot toward the rotating frame 3. The bottom plate 6 in the cleaning chamber 1 is provided with a cylindrical discharge groove 10 on the side opposite to the shot machine 8. This discharge groove 10 is formed of a filter having a large number of pores smaller in diameter than the shot material 9, and on the outside side of the discharge groove 10, a shower is provided with a nozzle 11 for withdrawing water toward the discharge groove 10. Means 1
2 are provided along the discharge groove 10. Inside the discharge groove 10, a screw conveyor 13 is provided along the discharge groove 10, and one end of the screw conveyor 13 faces a discharge port 14 opened in the side wall of the cleaning chamber 1. A bucket conveyor 15 provided on the side of the cleaning chamber 1 is connected at its lower part to the screw conveyor 13 through the discharge port 14, and its upper part is connected to a chute 16.
Since this bucket conveyor 15 is provided in an attitude inclined toward the chute 16, when the bucket 15a of the bucket conveyor 15 discharges the shot material 9 toward the chute 16, the bucket 15
a is completely reversed and the shot material 9 is reliably released. A cleaning liquid tank 17 containing cleaning liquid is provided midway above the chute 16.
The cleaning liquid is dripped onto the shot material 9 passing through. Also, in the middle of shoot 16,
Hot water pipe 18 that supplies hot water into the chute 16
is provided. 19 in the figure is a hopper, which supplies the shot material 9 carried in from the chute 16 and hot water to the shot machine 8. This shot machine 8 is rotationally driven by a motor 20, and is provided so as to shoot a shot material 9 toward the grilled meat iron plate 2 or to inject hot water using the centrifugal force generated at that time. Incidentally, 21 is the rotary frame body 3
This is a motor that rotates the motor.

The operation of the cleaning device configured as above will be explained.

A grilled meat iron plate 2 is housed in a holding frame 4 of a rotary frame body 3 and is held therein. Next, the rotating frame 3 is driven to rotate, and the shot material 9 is shot toward the rotating frame 3 by the shot machine 8. As the rotary frame body 3 rotates, the grilled meat iron plate 2, which had been brought to one end 4b of the holding frame 4 as shown in a in FIG. 3, rotates toward the shot machine (not shown) in the front of the figure. When moved, both ends 4 of the holding frame 4 are in the state shown by b in FIG.
The difference in height between a and 4b becomes maximum, and it gradually moves in the direction of the arrow in the inclined holding frame 4, and reaches the other end 4a of the holding frame 4 in FIG. 3c. Also, when moving from the shot machine side to the opposite side, both ends 4a, 4 of the holding frame 4
The height difference of b is reversed, and one end 4b is lower and the other end 4a is higher, so the grilled meat iron plate 2 moves to the left in the figure.
It is rotated toward the shot machine in the state shown by a in FIG. 3. The rotating frame 3, which is formed into a triangular prism shape with a coarse wire mesh, has a shot material 9 inward from the ridgeline portion 4a between the grilled meat iron plates 2, 2.
Since the shot material 9 easily passes through, the shot material 9 also collides with the back surface of the grilled meat iron plate 2 located on the opposite surface of the ridge line portion. Therefore, with this cleaning device, both the front and back surfaces of the grilled meat iron plate 2 can be cleaned without having to turn over and reset the grilled meat iron plate 2 during the cleaning operation.

The shot material 9 shot toward the grilled meat iron plate 2 and the deposits removed by the shot material 9 fall to the lower part of the cleaning chamber 1, and are collected by the bottom plate 6. Next, wide rubber plates 5 planted on three sides of the rotating rotating frame 3 sweep the shot material 9 on the bottom plate 6 into the discharge groove 10. The deposits remaining on the surface of the shot material 9 are washed away by the withdrawal of water from the shower means 12, pass through the pores of the discharge groove 10, and fall downward. Therefore, the deposits do not clog the pores of the discharge groove 10. The shot material 9 from which the deposits have been washed away is transferred to the lower part of the bucket conveyor 15 by the screw conveyor 13. The bucket conveyor 15 transports the shot material 9 to a chute 16 at the top of the cleaning device, and the chute 16 supplies the shot material 9 to the shot machine 8 via a hopper 19. When the shot material 9 passes through the chute 16, it receives a supply of cleaning liquid dripped from a cleaning tank 17. This cleaning liquid is useful for cleaning the shot material 9 itself, and is also used for cleaning the surface of the grilled meat iron plate 2.

In this way, in this cleaning device, the grilled meat iron plate 2 rotates and moves along with the rotation of the rotating frame 3.
Since it repeatedly moves back and forth in the direction of the axis 3a,
It is possible to prevent uneven shots on the surface of the grilled meat iron plate 2. Further, since the shot material 9 is used in circulation and the dirt transferred to the shot material 9 is removed by the water washing and cleaning liquid along the way, excellent cleaning effects are maintained over a long period of time.

When the predetermined cleaning is completed, the screw conveyor 13 and the bucket conveyor 15 are stopped while the rotary frame body 3 is kept rotating, and hot water is supplied into the chute 16 from the hot water supply pipe 18. The hot water flows into the shot machine 8 through the hopper 19, and is projected by the shot machine 8 toward the grilled meat iron plate 2. This hot water washes off the surface of the grilled meat iron plate 2, flows down onto the circumferential surface 7, and is swept into the discharge groove 10 by the rubber plate 5. As a result, the grilled meat iron plate 2 is rinsed, and the inner surface of the cleaning chamber 1 and the rotating frame 3 are rinsed.
Dirt that adheres to the surface is also washed away. After rinsing for a predetermined period of time, the grilled meat iron plate 2 can be taken out from the cleaning chamber 1 in a substantially dry state.

A second embodiment of the present invention is shown in FIGS. 4 and 5.

In this embodiment, the rotating frame (rotating body) 3 is formed into a substantially truncated pyramid shape, and the left end 4a of the holding frame 4 is held low at a position above the axis 3a of the rotating frame 3, as shown in FIG. The holding frame 4 is provided so that the right end 4b of the frame 4 is raised and the heights of both ends 4a, 4b of the holding frame 4 are reversed at a position below the axis 3a, and
A shot machine 8 is installed above the rotating frame 3. The holding frame 4 is composed of a coarse wire mesh forming the outer periphery of the rotating frame 3 and a pair of guide rails 4d, 4d provided inside the wire mesh. The rest of the configuration is the same as that of the first embodiment, and the effects of this embodiment are also substantially the same as those of the first embodiment.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, the rotating body can be provided by tilting the axis of the rotating body.

(Effects of the Invention) Since the present invention has the above-described configuration and operation, shot unevenness on the surface of the object to be cleaned is eliminated, and as a result, it is possible to provide a cleaning device that can evenly clean the surface of the object to be cleaned.
