In each drawing, arrows indicate the directions in which the powder spraying device 1 is installed in the noodle manufacturing device as shown in FIG. Incidentally, here, the downstream side of the conveyor 6 is defined as the "forward" direction, and each direction is displayed with the operator facing forward. Each direction is similarly displayed in each figure after FIG. 4 . In the following, the explanation regarding the direction will be described with reference to this direction.

As shown in FIG. 3, a housing (corresponding to the first housing) 38a of the powder spreader 3 and a flange portion 38d at the lower end of the housing of the powder grinder 2 (corresponding to the second housing) 20 is fastened and fixed by a plurality of fastening means 24 to the flange portion 20a of the upper end portion of 20 . Each fastening means 24 is composed of a bolt 24a and a nut 24b. Therefore, the powder spreader 3 and the powder grinder 2 are separably connected. That is, the powder spreader 3 and the powder grinder 2 can be combined and used as the powder spreader 1, and the powder spreader 3 alone can also be used. Legs 25L and 25R, which are L-shaped angles bent in the same manner as the flange 38d of the housing 38a of the powder applicator 3, are welded to the lower end of the housing 20 and fixed. By fastening and fixing the legs 25L and 25R to the upper portion of the conveyor 6 with bolts and nuts, the powder spraying device 1 is fixed in a state straddling the conveyor 6 in the left-right direction (see FIG. 1). 2 and 3 show the internal configuration of the powder grinder 2, and the case 38a or the mesh body 32 of the powder applicator 3, but the illustration of other internal configurations is omitted. ing.

<Structure of Powder Spreader 3>
5 to 7 show the configuration of the powder spreader 3 forming a part of the powder spreader 1. FIG. The powder applicator 3 includes a hopper 31 that accommodates dusting powder such as hard flour, potato starch, buckwheat flour, etc. in a housing 38a. The hopper 31 has an opening forming a dusting powder inlet 31b at its upper portion and a dusting powder outlet (corresponding to a powder spraying port) 31c at its lower portion. As shown in FIG. 6, the hopper 31 is gradually narrowed in front-rear opening dimension from the inlet 31b toward the outlet 31c. The inlet 31b is covered with a cover 38c so as to be openable and closable. A handle 38b is provided integrally with the upper portion of the lid 38c so that the operator can easily grip it when opening and closing the lid 38c.

Before and after the outlet 31c of the hopper 31, the lower end of the hopper 31 is cut and raised in a right angle direction (not strictly perpendicular) to form a flange portion 31a. In addition, the outlet 31c is provided with a mesh body 32 which can be attached in a state of closing the outlet 31c and has a large number of through holes 32a through which the dusting powder passes corresponding to the opening surface of the outlet 31c. (See FIG. 7). The portion of the mesh body 32 that closes the outlet 31c has an arcuate cross-section that is convex downward, and the arcuate shape is such that the central axis of the arcuate surface extends in the left-right direction. Front and rear end portions of the arc-shaped arc are bent radially outward of the arc surface to form bent portions 32b (see FIG. 6). When the mesh body 32 is attached so as to block the outlet 31c, the bent portion 32b is formed so as to contact the lower surface of the flange portion 31a by face-to-face contact.

A brush body 33 is provided inside the hopper 31 near the outlet 31c (see FIG. 6). The brush body 33 is rotatably fixed to the hopper 31 by a rotating shaft 33a extending in the left-right direction. When the brush body 33 is rotated by a rotary shaft 33a, the outer peripheral edge of the brush comes into contact with the inner peripheral surface of the mesh body 32 and rotates, pushing out the dusting powder placed on the mesh body 32 from the through holes 32a. function as The rotary shaft 33a is driven to rotate via a speed reducer 39b (see FIG. 5) by a motor 39a (see FIGS. 6 and 7) fixed to the inner wall of the housing 38a.

A frame 34 is provided on the lower surface of the mesh body 32 to hold the mesh body 32 in a state where the outlet 31c of the hopper 31 is closed. The frame body 34 presses the entire periphery of the edge portion of the mesh body 32 excluding the central portion where the through holes 32a are formed from the lower surface side of the mesh body 32 (the side of the arc-shaped outer peripheral surface side of the mesh body 32). It has a shape (see FIG. 7). A first frame side 34a extending in the left-right direction (the direction of the rotating shaft 33a of the brush body 33) of the frame body 34 presses one flange part 31a across one bent part 32b of the mesh body 32 (see FIG. 6). . A second frame side 34b parallel to the first frame side 34a presses the other flange portion 31a across the other bent portion 32b of the mesh body 32 . The third frame sides 34c on the left and right sides connecting the ends of the first frame side 34a and the second frame side 34b are formed in an arc shape concentric with the arc shape of the mesh body 32 so as to follow the arc shape of the mesh body 32. formed. Therefore, the left and right ends of the mesh body 32 are pressed against the arcuate surface of the lower part of the hopper 31 by the third frame side 34c and fixed.

The first frame side 34a is rotatably fixed to the outlet 31c of the hopper 31 by a pair of hinges 35 distributed in the horizontal direction. In the hinge 35, one mounting piece portion 35a of a pair of mounting piece portions whose relative angle is changeable around a hinge shaft 35c is fixed to the surface forming the outlet 31c of the hopper 31 via a spacer 35d. ing. The spacer 35d eliminates a step so that one attachment piece 35a can be fixed to the outlet 31c of the hopper 31 even if the outlet 31c of the hopper 31 has a flange 31a. Therefore, the height of the spacer 35d from the surface of the outlet 31c of the hopper 31 is substantially equal to the height of the flange portion 31a from the same surface, or slightly higher than the height of the flange portion 31a. In the hinge 35, the first frame side 34a of the frame 34 is fixed to the other mounting piece portion 35b of the pair of mounting piece portions.

A pair of hooks 36 engaged with a latch portion 37d of a toggle latch 37, which will be described later, is dispersedly arranged in the left-right direction and fixed to the second frame side 34b. Each hook 36 is fixed so that its tip protrudes from the outer circumference of the frame 34 (see FIGS. 6 and 7).

A pair of toggle latches 37 are fixed to the surface of the hopper 31 facing each hook 36 in a state where the frame 34 is pressed against the lower surface of the flange portion 31a with the mesh 32 interposed therebetween. The toggle latch 37 itself is a known one and is fixed to the surface of the outlet 31c of the hopper 31 via a spacer 37b. Like the spacer 35d, the spacer 37b eliminates a step so that the toggle latch 37 can be fixed to the surface of the outlet 31c of the hopper 31 even if the outlet 31c of the hopper 31 has the flange portion 31a. Therefore, the height of the spacer 37b from the surface of the outlet 31c of the hopper 31 is substantially equal to the height of the flange portion 31a from the same surface, or slightly higher than the height of the flange portion 31a. Therefore, by engaging the distal end portion 37g of the latch portion 37d of the toggle latch 37 with the distal end portion of the hook 36 and tilting the toggle lever 37c, the frame body 34 is pressed against the flange portion 31a of the hopper 31 and fixed. can do.

<Action and effect of the powder spreader 3>
The mesh body 32 is sandwiched between frames 34 and attached to the lower surface of the flange portion 31 a of the hopper 31 . The frame body 34 engages the tip 37g of the latch portion 37d of the toggle latch 37 with the hook 36 and operates the toggle lever 37c so as to be parallel to the base 37a, thereby attaching the spring 37e of the latch portion 37d. By applying force to the hook 36, the second frame side 34b of the frame 34 is strongly pressed against the lower surface of the flange portion 31a and fixed. In FIG. 6, in order to make the structure easier to understand, gaps are shown between the front and rear flange portions 31a and the front and rear bent portions 32b of the mesh body 32. The bent portions 32b are in contact with each other without gaps.

On the other hand, when removing the mesh body 32 from the flange portion 31a of the hopper 31 to replace or remove the clogging, the toggle lever 37c of the toggle latch 37 is rotated in the direction away from the base 37a to move the tip of the latch portion 37d. By removing the portion 37g from the state of engagement with the hook 36, the frame 34 can be rotated around the hinge 35, and the mesh body 32 can be removed from the flange portion 31a of the hopper 31. FIG.

In this manner, the mesh body 32 can be attached and detached simply by rotating the toggle lever 37c of the toggle latch 37 to open and close the frame body 34 about the hinge 35. FIG. Therefore, even if the mesh body 32 needs to be exchanged or clogged, and the mesh body 32 is attached and detached, compared to the case where the mesh body is fixed using bolts and nuts as in the conventional technology, According to the powder applicator 3, it is possible to increase the productivity of the production of noodles and the like.

<Configuration of the powder grinder 2>
2 and 3 show the powder grinder 2 together with the powder spreader 3 in a state fixed to the lower portion of the powder spreader 3. FIG. Moreover, FIG. 4 shows the powder grinder 2 alone. In FIG. 3, the left side portion of the rotating brush body 21R is shown in cross section.

As shown in FIG. 2, the powder grinder 2 includes a pair of rotating brush bodies 21F and 21R inside the housing 20 corresponding to the lower side of the mesh body 32 of the powder spreader 3. As shown in FIG. The pair of rotating brush bodies 21F and 21R are rotatably fixed to the housing 20 through respective bearings 21c at their rotating shafts 21b. The rotating shafts 21b are parallel to each other, and are arranged close to each other so that the outer peripheral ends of the brushes 21a of the rotating brush bodies 21F and 21R are in contact with each other. Further, each rotating shaft 21b is arranged with the direction (horizontal direction) that intersects the falling direction of the dusting powder spread from the powder spreader 3 as the axial direction.

A sprocket 21d is fixed to the left end of the rotating shaft 21b of the rotating brush body 21R on the rear side among the rotating shafts 21b. The sprocket 21d can be rotationally driven by a sprocket 23a fixed to an output shaft (not shown) of the motor 23 via a chain 23b. A gear 21e is fixed to the right end of each rotating shaft 21b of the pair of rotating brush bodies 21F and 21R (only the gear 21e of the rotating brush body 21R is shown in FIG. 3). The gears 21e are arranged in mesh with each other. Therefore, the pair of rotating brush bodies 21F and 21R can be simultaneously driven to rotate in directions opposite to each other by the motor 23. As shown in FIG. The rotating direction of the pair of rotating brush bodies 21F and 21R is such that the abutting portions of the brushes 21a both face downward, as indicated by arrows in FIG. As shown in FIGS. 3 and 4, each sprocket 21d, 23a and chain 23b are covered with a chain cover 21j. Each gear 21e is covered with a gear cover 21g.

As shown in FIG. 2, partition plates 20b are provided on both front and rear sides of the pair of rotating brush bodies 21F and 21R. Both ends of each partition plate 20b are fixed to the inner wall of the housing 20 so as to divide the inner region of the housing 20 into a region 20d containing the pair of rotating brush bodies 21F and 21R and a region 20e containing the motor 23. . A pair of plate-like guide plates 22F, 22R are provided above the region 20d including the pair of rotating brush bodies 21F, 21R so as to face each other in the front-rear direction. The pair of guide plates 22F and 22R are fixed on the respective partition plates 20b while being inclined such that the distance between the guide plates 22F and 22R facing each other is smaller in the lower direction than in the upper direction. Each of the guide plates 22F and 22R is a bent plate bent at an acute angle in the front-rear direction with a bending angle larger than a right angle, and flange portions 22a for reinforcement are formed at the left and right ends, respectively. As a result, the area 20d sandwiched between the partition plates 20b is covered with the guide plates 22F and 22R except for the gap between the pair of guide plates 22F and 22R.

On the other hand, the lower part of the area 20d sandwiched between the partition plates 20b is open, but the stay metal fittings 21i are provided below the rotating brush bodies 21F and 21R. The stay fitting 21i is a plate-like body, and is fixed to the inner wall of the housing 20 with its plate surface directed in the front-rear direction. A scraper 21h is fixed to the upper end portion of the stay fitting 21i. The upper end of the scraper 21h is arranged in contact with the outer peripheral end of each brush 21a of each rotating brush body 21F, 21R. Therefore, when the rotating brush bodies 21F and 21R rotate, the outer peripheral end of each brush 21a collides with the tip of the scraper 21h, causing each brush 21a to vibrate, and the dust adhering to each brush 21a is shaken off. be.

As shown in FIG. 2, when the powder spreader 3 is fixed to the upper portion of the powder grinder 2 and used, the upper portions of the pair of guide plates 22F and 22R are inserted into the lower portion of the powder spreader 3. state. Then, the mesh body 32 fixed to the outlet 31c of the hopper 31 of the powder crusher 2 is sandwiched from the front and rear inside the gap between the pair of guide plates 22F and 22R. Therefore, the dusting powder sprinkled from the through-holes 32a of the mesh body 32 is guided by the opposing inner side surfaces of the pair of guide plates 22F, 22R, and spreads from the pair of guide plates 22F, 22R to the pair of rotating brush bodies 21F, 21R. supplied on top of

The lower ends of the pair of guide plates 22F, 22R are arranged above along the respective rotating shafts 21b of the pair of rotating brush bodies 21F, 21R. The gap between the lower ends of the pair of guide plates 22F and 22R is approximately the same as the distance between the rotating shafts 21b of the pair of rotating brush bodies 21F and 21R. Therefore, as shown in FIGS. 2 and 4, the outer peripheral width (front-to-rear width) of the entire brush 21a integrally formed by contacting the outer peripheral ends of the brushes 21a of the pair of rotating brush bodies 21F and 21R is , the gap (front-to-rear width) between the lower ends of the pair of guide plates 22F and 22R viewed from above in the falling direction of the dusting powder is reduced. On the other hand, the lateral width of the pair of guide plates 22F and 22R is the same as the inner portion of the housing 20, and is slightly larger than the lateral width of each brush 21a of the pair of rotating brush bodies 21F and 21R. (See Figures 3 and 4).

In the powder spreader 3 and the powder grinder 2, the parts that come into contact with the dusting powder and the housings 38a and 20 are made of stainless steel in consideration of hygiene. The brushes of the brush body 33 and the brushes 21a of the pair of rotating brush bodies 21F and 21R are made of resin.

The dusting powder spread from the mesh body 32 of the powder spreader 3 is guided by the pair of guide plates 22F, 22R and conveyed to the outer periphery of the pair of rotating brush bodies 21F, 21R. The dusting powder is pulverized by contact between the outer peripheral ends of the brushes 21a of the pair of rotating brush bodies 21F and 21R while being transported on the brushes 21a by the rotation of the pair of rotating brush bodies 21F and 21R. That is, the dusting powder carried by one brush 21a is pulverized by the tip of the other brush 21a. The pulverized dusting powder is carried on each brush 21a by the rotation of the pair of rotating brush bodies 21F and 21R, and falls downward from the contact portion of the brushes 21a of the pair of rotating brush bodies 21F and 21R. It is spread on the surface of the noodles (objects to be spread) conveyed on the conveyor 6 .

The gap between the lower end portions of the pair of guide plates 22F and 22R is narrower than the outer peripheral width of the entire brush 21a of the pair of rotating brush bodies 21F and 21R. Therefore, the dusting powder guided by the pair of guide plates 22F, 22R is supplied without omission to the brushes 21a of the pair of rotating brush bodies 21F, 21R. Therefore, the lump of powder can be pulverized and sprayed without waste.

Each brush 21a of the pair of rotating brush bodies 21F and 21R is covered with a partition plate 20b and a pair of guide plates 22F and 22R around the entire periphery except for the lower portion thereof and the gap between the pair of guide plates 22F and 22R. ing. Therefore, the dusting powder is spread on the surface of the noodles with a high yield without being spread over the surface of the noodles.
