Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a material supply device for expanded rice crackers.

(Prior Art) A conventional material supply device for expanded rice crackers consists of a hopper for storing expanded rice cracker materials, and a supply device that intermittently supplies a fixed amount of the material in the hopper.

(Problem to be solved by the invention) Since the above-mentioned conventional device does not have an adjusting means to ensure that the ingredients are supplied in an optimal distribution into the baking mold, the periphery of the rice cracker that has been baked into the rabbit hole may be chipped, or the inside of the rice cracker may be chipped. This resulted in poor quality, such as the formation of partially recessed portions, resulting in poor yields.

This invention was made to solve this problem, and it is a material that can supply the rice cracker ingredients in the baking mold in an optimal distribution in order to make the baked rice crackers beautifully shaped. The purpose is to provide a feeding device.

(Means for Solving the Problems) In the present invention to achieve the above object, the lower end opening of the cylindrical guide tube is formed into an enlarged cylindrical body concentric with the guide tube, and the peripheral wall of the guide tube has a radius of In addition to threading bolts of a predetermined length in multiple stages and appropriately arranged in the direction, and threading bolts of a predetermined length downward from the donut-shaped top plate of the enlarged cylindrical body. It is characterized by a scattering object with a conical head placed at the center of the device.

(Function) The material supply pipe of the present invention is used in an upright position with the enlarged cylindrical body facing downward.

However, when a certain amount of material is supplied at once from the upper end opening of the guide tube, it falls while being subjected to flow resistance etc. by the adjusted bolt, and is finally placed in the baking mold located directly below the expanding cylindrical body. Supplied as a distribution. At this time, the rice cracker material is supplied to the periphery of the baking mold in a relatively larger amount than the center.

(Embodiment) Hereinafter, one embodiment of the device of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a perspective view thereof, Fig. 2 is a perspective explanatory view of a material supply device equipped with the device of the present invention, Fig. 3 is a partial cross-sectional view of the material dividing device, and Fig. 4 shows the distribution of rice grains in the baking mold. The plan view explanatory diagram shown in FIG. 5 is a partial sectional view of the proposed device of our school.

In the figure, 1 is a fixed hopper for storing the ingredients for expanded rice crackers, that is, rice grains m. A communication pipe 2 extends downward from the outlet 1a of the hopper 1, and is biased downward by a spring or the like if necessary.

3 is a material dividing supply device that feeds rice grains m in the hopper 1.
It is divided into fixed amounts and supplied to fixed locations, and is constructed as follows. That is, a transport disc 6 is mounted concentrically to a fixed disc 5 in which a drop hole 4 (see FIG. 3) is provided so as to be rotatable about an axis 7, and the transport disc 6 is By connecting the rod 8a of the drive cylinder device 8 with the rod 8a of the drive cylinder device 8, the conveying disk body 6 can be freely driven to swing around the shaft 7. Also, a stepped conveying hole 9 is provided in the conveying disk body 6, and the hole 9 is made swingable. It is positioned directly below the exit of the hopper 1 at the swing start point s, while it is set to match the drop hole 4 at the swing end point f, and a conveyance amount adjustment cup 10 is fitted into the hole 9. . Thus, the rice grains m in the hopper 1 are introduced into the inner hole 10a of the conveyance amount adjusting cup 10 through the connecting pipe 2 at the swinging start point s of the conveying disc body 6, and at the swinging end point f. The rice grains m in the inner hole 10a are made to fall from the drop hole 4.

Reference numeral 11 denotes a stirring device consisting of a motor 12 and a stirring rod 13, and the tip of the stirring rod 13 is made to reach the lower end of the communication pipe 2. As a result, if the device 11 is kept in operation while the dividing device 3 is in operation, the rice grains m can be prevented from causing a bridging phenomenon in the hopper 1 or in the connecting pipe 2 and being obstructed from falling, thereby ensuring that the rice grains m are kept in the cup. It will be supplied in fixed quantities to Note that 14 is a fixing member for the motor 12.

Reference numeral 15 denotes a rice cracker material supply pipe which is the main part of the present invention, and the lower end opening of the cylindrical guide pipe 16 is connected to the pipe 16.
It is formed into an enlarged cylindrical body 17 concentric with . The cylindrical guide tube 16 has its upper end communicated with the drop hole 4, and bolts 18 of a predetermined length are threaded into the peripheral wall thereof in opposite directions in the radial direction. It is provided in multiple stages while changing. Each of the bolts 18 is made long enough to reach the center of the cylindrical guide tube 16 in its most screwed state, but it can be made longer if it is not opposed to each other, that is, if it is staggered. The enlarged cylindrical body 17 has a lower end open and an upper end closed with a donut-shaped top plate 17a, and a suitable number of bolts 19 of a predetermined length are inserted downward from the top plate 17a. It is screwed on.
It is preferable that the bolt 19 be configured such that its tip reaches the lowest end of the cylindrical body 17 when it is fully screwed in. Further, at the center of the cylindrical body 17, a scattering body 20 whose head is formed into a conical surface 20a is fixed with a thick wire 21 or the like along the central axis direction of the cylindrical body 17, and the conical surface 20a The tip of the guide tube 16 is directed straight toward the inner center of the guide tube 16. Note that 22 is a brush extending from the lower edge of the enlarged cylindrical body 17 and is fixed to the inner surface of the circumferential wall of the enlarged cylindrical body 17 under pressure by a spring plate 23 .

A sensor 24 detects the presence of a baking mold 26 located on a horizontal table 25 directly below the enlarged cylindrical body 17. Based on this detection signal, the rod 8 of the cylinder device 7 is displaced in a forward direction. It is configured to perform a backward displacement when the signal disappears.

The method of use and operation of the above configuration will be explained. With rice grains m stored in the hopper 1 in advance and the stirring device 11 activated, the operator places the baking mold 26 on the horizontal platform 2 directly below the enlarged cylindrical body 17.
5. Insert by sliding the top. As a result, the sensor 24 and the cylinder device 8 are operated in conjunction with each other to displace the conveying disc body 6 from the swinging start point s to the swinging end point f. Therefore, the inner hole 1 of the conveyance amount adjustment cup 10
The rice grains m contained in 0a are conveyed to the drop hole 4, and are dropped all at once from there. In order to adjust the conveyance amount of the rice grains m, conveyance amount adjusting cups 10 having different diameters of the inner holes 10a are used.

The guide cylindrical tube 16 thus guides the dropped group of rice grains a downward, and at this time the plurality of bolts 18 act as flow resistance on the falling rice grains m. Therefore, by appropriately adjusting the amount of inflow and outflow of each bolt 18, regardless of changes in the situation of the cylindrical guide tube 16 (for example, changes in verticality, etc.), it is possible to equalize the dispersion of the rice grains m at the lower part of the cylindrical guide tube 16 and to adjust its falling speed. can be made to an appropriate size.

Thereafter, the conical surface 20a of the scattering body 20 partially scatters the rice grains m that have reached the lower part of the cylindrical guide tube 16 in the radial direction of the enlarged cylindrical body 17. 19 affects the falling situation. Here, if a particular bolt 19 is screwed downward, the amount of rice grains m falling directly below it will decrease, and conversely, if it is pulled out upwards, the amount of rice grains m falling directly below it will tend to increase. If the amount of inflow and outflow of the bolt 19 is adjusted appropriately, a group of falling rice grains m will fall within the enlarged cylinder 17 in a predetermined variation state, and the rice grains m will fall.
is supplied to the outer periphery (shaded area in FIG. 4) of the baking mold 26 in a relatively larger amount than to the center.

Next, the baking mold 26 is taken out from directly below the enlarged cylindrical body 17, but the detection signal from the sensor 24 disappears and the conveying disk body 6 is returned to the swing starting point s by the cylinder device 7. At this point, the rice grains m are again supplied into the inner hole 10a of the conveyance amount adjusting cup 10, and the device 3 prepares for the next conveyance.

On the other hand, the baking mold 26 into which the rice grains m have been supplied is covered with a lid 28 as shown in FIG.
Displace it downward and press it. In this state, baking mold 2
6 and the lid 28 with a burner 30 or the like, the pressing body 29 is instantly displaced upward. As a result, the rice grains m expand in the baking mold 26 and are formed into a predetermined shape, but since a relatively large amount of rice grains m are supplied to the outer periphery of the baking mold 26, the outer periphery of the baked rice cracker. The compaction density of the rice grains m increases, and a beautiful rice cracker with a square outer edge and a good quality can be obtained.

(Effect of the invention) As described above, according to the invention, one bolt is attached to the pipe body.
8, 19 and the scattering body 20, it is possible to supply the rice grains m in an optimal distribution (that is, a state in which the rice grains m are more abundant at the outer periphery and less at the center inside the baking mold 26), For this reason, high quality rice crackers with angular outer edges can be obtained with high reliability and high productivity.
