Description

[Detailed Description of the Invention] () Background Technical Field of the Invention The present invention relates to the use of materials such as viscous bodies, powders, liquids, and not only food materials but also construction aggregates and pharmaceuticals intermittently. The present invention relates to a quantitative dividing machine that delivers a fixed amount of rice cakes at a time, and particularly to a quantitative dividing machine that can reliably and efficiently cut extremely viscous materials such as freshly made rice cakes, which are delivered in a continuous state from a nozzle.

Prior art and its problems There are three main types of conventional quantitative dividing machines, all of which are equipped with a hopper and an intermittent supply device that intermittently delivers the material in the hopper. The screw-type one shown in Figure 1,
There are a roller type shown in FIG. 2, and a combination of a piston and a switching valve as shown in FIG. 3.

In detail, the quantitative dividing machine shown in FIG. 1 is equipped with a screw 2 in the bottom of a hopper 1, and the screw 2 is intermittently driven by a motor 3 to intermittently divide the material M in the hopper 1. The nozzle 4 sends out a fixed amount at a time.

In addition, in the quantitative dividing machine shown in FIG. 2, the hopper 1 has rollers 5, 5 at the bottom, pulleys 6, 6 attached to the shafts of the rollers 5, 5 are crossed by a belt 7, and a motor 3 moves the rollers. 5 and 5 are rotated, the material M in the hopper 1 is transferred to the nozzle 4.
It is designed to intermittently send a fixed amount to the outside.

Further, in the quantitative dividing machine shown in FIG. 3, the inlet 8a of the switching valve 8 is connected to the outlet side 1a of the hopper 1.
Furthermore, a cylinder 9 is connected to the outlet 8b of the valve 8, and a nozzle 4 is connected to the other outlet 8c.
is connected, and when the outlet 8c is closed by the valve body 8d, the piston 9a is pulled and the material M in the hopper 1 is intermittently delivered in fixed amounts to the outside from the nozzle 4.

In any of the quantitative dividing machines shown in FIG. 1 to FIG.
It is necessary to cut the material that is intermittently delivered from the conveyor by cutter means and drop it onto the conveyor.
Conventionally, the following cutter means was provided near the nozzle.

The cutter means shown in FIG.
0, apply rice flour or potato starch to the cutter for each cut, and cut the viscous material M by pinching the constricted part sent out from the nozzle 4 to the outside with the cutters 10, 10. It is something that is dropped on top.

However, in these cutters 10, 10, even though rice flour, etc. is applied to the cutters as described above, material dregs gradually accumulate in the cutters, and the cutters become dull, making it difficult to perform quantitative division. There is.

In particular, when the viscosity is extremely high, such as freshly made mochi, cutting cannot be performed well from the beginning, and this has hindered the full automation of quantitative dividing machines for quantitatively dividing viscous materials, and there are still no nozzles. Currently, the cutting of the rice cakes sent out from No. 4 relies on manual labor.

The cutter means 11 shown in FIG.
It is for cutting.

However, since this cutter means 11 has a thin wall thickness, as cutting progresses, the tip of the cutter bends downward under the pressure of feeding the material M, and the nozzle 4
Since the cutter is slightly separated from the outlet end of the nozzle 4, the cutting quality is poor from the beginning.Additionally, the cutter of the material M gradually adheres to the outlet end of the nozzle 4 in a direction perpendicular to the cutting direction, and the cutting becomes even better. This has hindered full automation.

Furthermore, in the above case, if the thickness of the cutter 11 is made thicker in order to eliminate the bending of the tip of the cutter, rice cake dregs will adhere not only to the nozzle 4 but also to the cutter 11, resulting in poor cutting ability. Even after cutting, the rice cakes remain connected, making rapid quantitative division impossible, and also hindering full automation.

() Purpose of the invention The present invention was devised in view of the above points, and
By improving the cutter means so that it does not lose its sharpness over time, it can be used to cut materials that are extremely viscous, such as freshly made rice cake, and cannot be cut well even with a sharp cutter. The present invention provides a quantitative dividing machine that can cut viscous materials well, fully automate the process of dropping viscous materials onto a conveyor, and can also perform quantitative division of other materials.

() Detailed Description of the Invention The quantitative dividing machine of the present invention has improved nozzles and cutter means as its main parts.

The quantitative dividing machine of the present invention includes a hopper, an intermittent supply device provided on the outlet side of the hopper and intermittently supplying the material in the hopper, and a It is not particularly different from the conventional structure in that it consists of a nozzle that sends out the material in the vertical direction to the outside, and a cutter means that cuts the material sent out from the nozzle near the nozzle. It may be of any format shown in FIG.

Therefore, since the hopper and the intermittent feeding device are not shown in the drawings, they should be understood in terms of the corresponding components in FIGS. 1 to 3.

Hereinafter, improvements to the nozzle and cutter means will be explained with reference to FIGS. 6a and 6b.

In FIG. 6a, at least the lower end outlet 4a of the nozzle 4 faces vertically downward in order to send the material from the intermittent supply device (not shown) onto a conveyor (not shown) vertically downward.

In order for the nozzle to smoothly cut the viscous material, the lower end outlet 4a does not need to have a uniform passage cross section from the upper end of the nozzle to the lower end of the nozzle. Preferably, the cross-sectional area at the lower end of the passage is smaller than that at the upper end, as shown in the figure.

As shown in FIGS. 7a and 7b, the nozzle 4 has a notch 13 formed by opening one side wall 4b forming the lower end outlet 4a by the same width W as the nozzle passage.
have.

Preferably, by providing the notch 13, no step is formed at the lower end outlet 4a of the nozzle passage.

The cutter means for cutting the material delivered from the nozzle 4 consists of an arm 14 and a cutter 15 attached to the lower end of the arm.

As can be seen from FIG. 6b, the arm 14 is
The upper end portion 14a is bifurcated to sandwich the nozzle 4, and each of the upper end portions 14a, 14a is pivotally fixed to pins 16, 16 provided at the upper part of the outer surface of the nozzle 4, so that the lower end side can pivot. The rear end of the cutter 15 is fixed to the lower end 14b of the arm with a screw or the like.

A shim 19 is sandwiched between the lower end 14b of the arm and the rear end of the cutter 15 to adjust the sliding fit between the cutter 15 and the cut end surface 13a.

As can be seen from FIG. 6a, when the cutter 15 enters the lower outlet of the nozzle passage, the upper surface portion 15b facing the inside of the passage slides into a notch end surface 13a shown with a reference numeral in FIG. It's summery.

Therefore, preferably, the upper surface portion 15b is a cylindrical surface with the radius of curvature R centered around the rotation center, and the notch end surface 13a is also a cylindrical surface with the radius of curvature R around the rotation center. ing.

Further, as can be seen from FIG. 6b, the cutter 15 has a tip 15c that enters the notch 13 and has a width W that is approximately the same as the width of the nozzle passages on both sides adjacent to the notch 13, and The shape corresponds to the cross section of the nozzle passage so that when it enters the nozzle passage through the notch 13, it comes into contact with the other side wall 4c facing the notch 13 of the nozzle and completely seals the lower outlet 4a of the nozzle passage. There is.

Therefore, in the cutter 15, the upper surface portion 15b is slidably fitted to the cutout end surface 13a, and the widthwise end surfaces 15d and 15e are also slidably fitted to the nozzle passage walls 4d and 4e, completely blocking the nozzle passage. ing.

The pivot portion at the upper end of the arm is arranged so that the angle at which the blade portion 15a of the cutter 15 enters the nozzle passage lower outlet 4a through the notch 3 shown in FIG. 7 in FIG. 6a is approximately horizontal to slightly It is designed to enter downward. For this reason, the pivot portion of the arm 14 must not be provided closer to the notch side of the nozzle 4 than a predetermined amount.

The arm 14 is connected to a suitable intermittent reciprocating arm drive means 17, such as a motor as shown or a cylinder device not shown.

When the intermittent supply device (not shown) stops driving, the intermittent reciprocating arm drive means 17 is driven in conjunction with this to close the cutter 15, which is in the open state, to the nozzle passage lower outlet 4a of the nozzle 4. There is.

Furthermore, the intermittent reciprocating arm drive means 17
is a suitable sensor, e.g. limit switch 1.
By detecting the rotation angle of the arm 14 with 8a and 18b, the drive of the cutter 15 is stopped at the same time as the outlet of the nozzle 4 is closed, and the cutter 1
5 is designed to stop driving when it is in the open position.

Note that the cross-sectional shape of the passage of the nozzle 4 is circular, and the cutter 15 may also be semicircular accordingly.

() Functions and effects of the invention The functions and effects of the quantitative dividing machine having the configuration described above will be explained by taking as an example the case of quantitatively dividing freshly made rice cake.

The quantitative dividing machine consists of a hopper, an intermittent feeding device, a nozzle, and a cutter means. First, when freshly made rice cake is put into the hopper, the intermittent feeding device causes the intermittent reciprocating arm drive means 17 to cutter. 15 is in an open state with respect to the nozzle outlet, rice cakes are intermittently supplied to the nozzle 4.

A certain amount of rice cake supplied to the nozzle 4 is released from pressure while being in a highly viscous barrel.
After being delivered from the nozzle, it swells into a dumpling shape, but the entire amount is not delivered from the nozzle 4 and remains connected to what remains inside the nozzle.

Then, the nozzle 4 has a notch 13, and the cutter means rotates the cutter at the tip of the rotating arm to close in conjunction with the stoppage of the drive of the intermittent supply device by the intermittent reciprocating arm drive means 17. Because of this structure, the cutter 15 enters the nozzle outlet through the notch 13 and cuts the constricted and connected portion of the rice cake with the blade portion 15a.

At this time, since the cutter 15 is attached to the arm 14, the upper surface portion 15b is slidably fitted with the notch end surface 13a and does not separate, and the notch end surface 13a plays the role of a doctor to scrape off the rice cake cake residue adhering to the upper surface portion 15b. As a result, rice cake does not get into the sliding portion, and both side surfaces 15d and 15e are connected to the nozzle passage wall 4.
Since the cutter 15 is slidably fitted with the cutter 15 and 4e, and rice cakes do not get into the slip-fitted portion, smooth operation of the cutter 15 is ensured and the cutter 15 does not become inoperable.

When the cutter 15 enters the nozzle passage lower outlet 4a, the angle of entry is approximately horizontal or slightly downward to cut the rice cake, and the cutter 15 does not enter upward to cut the rice cake. The cutter cuts the constricted and connected parts well, and at that time, the nozzle passage walls 4c, 4d, 4e
The lower end of the cutter 15 is aligned with the lower surface of the cutter 15, but is slightly lowered, so the nozzle passage walls 4c, 4
No rice cake residue is deposited on the lower ends of d and 4e, and cutting by the cutter 15 is not adversely affected.

If the lower ends of the nozzle passage walls 4c, 4d, and 4e are aligned with the upper surface of the cutter 15, rice cake dregs will adhere and accumulate on the lower ends of the nozzle passage walls 4c, 4d, and 4e during cutting. This will continue to be connected to the mochi that was cut with the cutter.

Therefore, complete automation can be realized even in a quantitative dividing machine that handles a fluid material having an extremely high viscosity such as freshly made rice cake.
