Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is used on the top surface of a conveyor such as an automatic dusting machine for commercial use, and is used to press and adhere powder to a workpiece and to remove excess powder. This invention relates to an improvement in a roller-shaped powder conveying machine that removes powder by adhering it to the surface of a rotor.

<Prior art> The applicant previously invented an automatic powdering machine shown in FIG.
However, the present invention is a further improvement of the roller (roller-shaped powder conveying machine).

The breading machine, which is an example of an automatic flouring machine, filed in Japanese Patent Application No. 61-66888 will be explained as follows.

As shown in FIG. 3, the breading machine is composed of a roller 110, a vacuum pump 120, a conveyor 130, an upper conveyor 140, and a receiving tank 150.

The conveyor 130 rotates in the X′ direction so that the workpiece 101 flows from the right side to the left side in the figure.
Above it, a receiving tank 150, an upper conveyor 140, and a roller 110 are arranged in this order from the front in the direction of movement of the conveyor 130, and on the end surface 111 of the roller 110 there are air pipes 121, 122 connected to a vacuum pump 120.

The roller 110 has approximately the same width as the conveyor 130, and only the plate 113 on the circumferential surface of the roller 110 is rotated in the Y' direction by the motor of the conveyor 130 on the conveyor 130 so as to be approximately in synchronization with the movement of the conveyor 130. This is what we are doing.

Then, the roller 110 moves the bread crumb adsorption section 11
The entire circumferential surface, except for 1 and the crumb separation part 112, is covered with a cover 114 at appropriate intervals.

The plate 113 on the circumferential surface of the roller 110 is a punched plate or wire mesh with small holes drilled in one side to prevent crumbs from entering. Then, the inside of the roller 110 is divided into two chambers, and the lower part of the roller is divided into two chambers.
11. The upper part is a crumb removal section 112, and part or all of the exhaust air from the vacuum pump 120 is sent to the crumb separation section 112 to provide a cleaning effect. Next, the function of this device will be explained.

In FIG. 1, the conveyor 130 is moving from the right side of the figure to the left side of the roller 110 (X' direction),
Lower breadcrumbs 10 from the right end to the left of the roller 110
2 is drawn and circulates.

The food, which is the workpiece 101 placed on the bottom crumb 102 at the right end of the conveyor 130, is conveyed to the lower part 152 of the receiving tank 150.

The workpiece 101 that has reached the lower part of the receiving tank 150 is covered with upper bread crumbs 103. Then, it is conveyed to rollers 110.

The roller 110 presses the workpiece 101 from above, and sticks the lower bread crumbs 102 and the upper bread crumbs 103 to the workpiece 101. Then, the excess top crumbs 103 are attracted to the surface of the roller 110 and removed.

When the sucked and removed bread crumbs reach the crumb detachment section 112 above the roller 110, they are blown away from the roller 110 by air sent from the vacuum pump 120 and separated.

The separated bread crumbs are conveyed to a receiving tank 150 by an upper conveyor 140.

The crumbs that have not been removed by the rollers 110 fall from between the nets of the conveyor 130 on the upper side (outward path 132) to the lower side (return path 131) and are removed.

The crumbs that have fallen onto the conveyor on the lower side (return path 131) are transported again to the starting end of the upper side (outward path 132) by the movement of the conveyor 130.

The workpiece 101 coated with bread crumbs is conveyed as it is to the left end by the conveyor 130.

<Problems to be Solved by the Invention> As shown in the conventional example above, it has been found that in order to efficiently press a workpiece with a roller, it is advantageous for a roller with a larger diameter to have a larger pressing area. However, there was a problem in that the larger the roller, the larger the volume inside the roller, which required a vacuum pump with a larger capacity.

An object of the present invention is to provide a roller-like powder conveying machine that solves the above problems.

<Means for solving the problem> The roller-like powder conveying machine 10 has a rotor 11,
It is composed of a rotor shaft 15 on which the rotor 11 is fixed rotatably and non-slidably, and a guide plate 19 provided along the outermost circumference of the rotor 11.
, a plurality of holes 12 are provided radially in the direction of the rotational axis of the rotor 11 from the surface to the rotor axis, and a filter 13 is inserted in the middle of the hole 12.
Provided to cover 2.

The rotor shaft 15 is constituted by a hollow pipe that is fixed in a non-rotatable manner, and is provided with an inlet 16 that communicates only with the hole 12 located at the lower part of the rotor 11, and maintains the inside thereof at a negative pressure.

The guide plate 19 covers the outer periphery of the rotor 11 from at least the bottom to the top in the rotational direction, excluding the contact surface with the conveyor 30.

The problem was solved by the above means.

<Function> The hole 12 located at the bottom of the rotor 11 communicates with the suction port 16 of the rotor shaft 15, creating a negative pressure.

The powder 3 is sucked into the hole 12 of the rotor 11,
It stops at filter 13.

The sucked powder 3 is directly transferred to the rotor 11
is pulled up by the rotation of the guide plate 19, and the hole 12 is covered with a lid.

At the same time as the lid is closed, the suction port 16 of the rotor shaft 15 is closed, and the hole 12 is no longer under negative pressure, but the powder 3 does not fall from the hole 12 of the rotor 11 because it is covered by the guide plate 19.

The powder 3 in the hole 12 of the rotor 11 is pulled up to the top as it is when the filter 13 is squeezed by the guide plate 19.

Passing the top of the rotor 11, the guide plate 19
When the powder 3 disappears, the powder 3 just stays in the hole 12 due to its own weight.

When the rotor 11 further rotates, the powder 3 falls due to its own weight.

<Example> Fig. 1 and Fig. 2 are structural diagrams showing an automatic breading machine using an embodiment of the roller-like flour conveying machine 10 of the present invention. FIG. 2 is a sectional view taken along the line AA in FIG. 1.

The explanation will be given below based on the figures.

An automatic breading machine using a roller-like powder conveyor, which is an embodiment of the present invention, is composed of a roller-like powder conveyor 10, a vacuum pump 20, a conveyor 30, an upper conveyor 40, and a receiving tank 50.

The conveyor 30 rotates in the X direction so that the workpiece 1 flows from the right side to the left side in the drawing. They are lined up in order of machine 10.

The roller-like powder conveyor 10 includes a rotor 11,
The rotor shaft 15 is composed of a rotor shaft 15 that fixes the rotor 11 in a rotatable but non-slidable manner, and a guide plate 19 provided along the outermost circumference of the rotor 11.
1 and 22.

The rotor 11 has approximately the same width as the conveyor 30, and is rotated in the Y direction about the rotor shaft 15 by the motor of the conveyor 30 above the conveyor 30 so as to be approximately in sync with the movement of the conveyor 30. It is.

The rotor 11 is covered with guide plates 19 provided along the outermost circumference of the rotor 11 at appropriate intervals from the bottom to the top in the rotational direction, except for the hole 12 located directly below.

The rotor 11 is a cylindrical body, and a plurality of elongated holes 12 having approximately the same width as the rotor 11 are provided radially in the direction of the rotational axis of the rotor 11, penetrating from the surface of the rotor 11 to the rotor axis 15. There is a filter 13 in the middle of the hole 12.
is provided so as to close the hole 12.

The filter 13 may be appropriately selected from those having meshes smaller than the flour 3 (bread crumbs) and having air permeability, such as a punched plate, wire mesh, cloth, etc.

It goes without saying that the holes 12...12 are not limited to the elongated holes in the above example, but may be holes of any shape as long as they are penetrating holes.

The rotor shaft 15 is a hollow cylinder whose end is closed and has an outer diameter that is approximately the same as the inner diameter of the rotor 11, and is fixed to the rotor 11 in a non-slidable but rotatable manner.

The inside of the rotor shaft 15 is divided into two chambers.
They are connected to the intake side and exhaust side of a vacuum pump 20, each driven by a motor (not shown). The chamber leading to the intake side has an inlet 16 that communicates only with the hole 12 at the bottom of the rotor 11, and the chamber leading to the exhaust has an exhaust port 18.

The exhaust port 18 has the effect of cleaning the eyes of the filter 13, and if the cleaning effect is not required, the rotor shaft 15 may be made into one chamber and only the suction side may be provided.

Adjustment valves 23 and 24 are provided in the middle of the air pipes 21 and 22 to adjust the amount of air blown to allow fine adjustment.

The upper conveyor 40 is a roller-like powder conveyor 10
A slope 41 is provided between the rotor 11 and the upper conveyor 40 on the right side of the rotor 11 in FIG.

Then, a conveyor 30 is used as a roller-like powder conveyor 10.
It plays the role of transporting the powder 3 that has been transported to the receiving tank 50.

The upper conveyor 40 may be appropriately selected from those having normal functions.

In this embodiment, the upper conveyor 40 is used to convey the material to the receiving tank 50, but it goes without saying that it may be replaced with a device having the same effect, such as a chute, a lift, etc.

The receive tank 50 has a large opening at the top,
The container has an approximately triangular shape in front view, with an elongated hole formed in the lower part thereof in a direction perpendicular to the traveling direction of the conveyor 30, extending over approximately the entire width of the conveyor 30.

The conveyor 30 is a net conveyor in which receiving plates 33 are provided under the upper side (outward path 31) and the lower side (return path 32), and the powder 3 remaining without being removed by the rotor 11 is transferred to the rotor 11 on the left side in FIG. The net is dropped through a hole 34 in the bottom of the net, and by the movement of the lower side of the conveyor (return path 31), it is carried to the upper side (outward path 32) and circulated.It is driven by a motor (not shown). ing.

The vacuum pump 20 may be appropriately selected from conventional ones, and the air flow by the vacuum pump 20 is as follows:
It looks like the small arrow in Figures 1 and 2.

Next, the operation of an automatic breading machine that is an embodiment of the present invention will be explained.

In FIG. 1, the conveyor 30 is rotating in the X direction from the right side to the left side in the drawing, and the powder 3 is ground and circulated from the right end to the left side of the roller powder conveyor 10.

The food, which is the workpiece 1 placed on the powder 3 at the right end of the conveyor 30, is transferred to the receiving tank 50.
carried to the bottom of the

Workpiece 1 that has come to the bottom of the receive tank 50
Powder 3 is sprinkled on top. The powder is then transported to a roller-like powder conveyor 10.

The rotor 11 of the roller-like powder conveyor 10 is Y
direction, presses the workpiece 1 from above, and sticks the upper and lower powders 3 onto the workpiece 1.

Then, the excess powder 3 is removed from the hole 12 of the roller 10.
is attracted to the surface of the filter 13 and removed.

When the powder 3 that has been sucked and removed reaches the guide plate 19 and is narrowed between the guide plate 19 and the filter 13, the hole 12 is no longer ventilated with the suction port 16 of the rotor shaft 15, and the filter 13 I can no longer be attracted to it.

The powder 3 is raised to the top while being confined by the hole 12 and the guide plate 19.

As the rotor 11 rotates, the powder 3 falls onto the upper conveyor 40 under its own weight.

The remaining powder 3 is blown away by the air coming out of the exhaust port 18 of the rotor shaft 15 and falls onto the upper conveyor 40.

The powder 3 that has fallen onto the upper conveyor 40 is conveyed to a receiving tank 50. (Rotating in the Z direction) Powder 3 that has not been removed by the roller-like powder conveyor 10 falls between the nets of the conveyor 30 on the upper side (outward path 32) to the lower side (return path 31) and is removed.

The powder 3 that has fallen onto the conveyor 30 on the lower side (return path 31) is transported again to the starting end of the upper side (outward path 32) by the movement of the conveyor 30.

The workpiece 1 coated with the powder 3 is conveyed as it is to the left end by the conveyor 30.

The above is an example of an automatic breading machine, but it goes without saying that the present invention is not limited to breadcrumbs, but can be used for any type of machine that uses powder.

<Effects of the Invention> As described above, the present invention provides a very useful and practical roller that is inexpensive, lightweight, and compact, since the capacity of the vacuum pump is smaller than that of conventional roller-type powder conveyors. The present invention provides a powder conveyor.
