Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a high viscosity confectionery forming apparatus for uniformly forming confectionery made of viscous substances such as gum and candy into a sheet shape.

(Prior art) Conventionally, in order to form a highly viscous substance such as sheet gum into a thin sheet, the gum is put into an extruder and heated in the extruder to make it viscous enough to be rolled. At the same time, the gum is extruded in a thick sheet form from a rectangular Ifr face nozzle which is the outlet of the extruder, and the gum is sequentially extruded while passing between upper and lower rolling rollers arranged in series in multiple stages at the exit. The thickness was reduced to produce a sheet of gum of the desired thickness.

The gum sheet rolled to a desired thickness is then cut into required dimensions to produce products.

However, since the gum in the sheet gum rolled by the above-mentioned forming apparatus is a high-viscosity substance, the gum rolled at the center of the rolling roller is surrounded by the high-viscosity gum on the left and right sides. The gum is uniformly stretched along the rolling direction, and the residual strain stress of the gum due to rolling is also arranged in the rolling direction.

On the other hand, in the case of rolled gum near both sides of the upper and lower rolling rollers, the gum tends to protrude toward both ends of the rolling rollers where there is less resistance, so the residual strain stress in the rolled gum is not in a constant direction and is This results in a strain stress array whose direction gradually changes from the width direction to the width direction.

However, for materials with restoring properties such as gum and candy, if they are aged for a certain period of time after rolling, the residual strain stress mentioned above will be restored. Only the dimensions change.

In this case, since the gum rolled at the center of the rolling roller has residual strain in a certain direction, the shape of the gum after aging is only expanded to similar dimensions, but the shape of the gum after aging is similar to that of the rolled gum. Regarding both side parts, as mentioned above, the direction of strain stress is uneven due to the dimension from the width end of the sheet-shaped gum board, so the restored dimensions after aging are not constant. However, there was a problem with the next packaging process.

For this reason, depending on the cut width, the unusable portion increases, and the utilization rate of the rolled gum (utilization rate - product usage amount ÷ rolling forming amount) decreases, reducing production efficiency.

In order to improve this, an apparatus has been proposed in which one of the upper and lower rolling rollers is a flange roller to improve the utilization rate.

In this device, one roller of a set of rolling rollers is fixed to a disk-shaped collar having a diameter larger than the roller diameter at both ends thereof, and the length of the other roller is fixed to the inner part of this collar. This device forms gum with a constant width direction by passing the gum through a rectangular shape that is bent by the upper and lower rollers and brim on both sides.

(Problems to be Solved by the Invention) However, when high-viscosity substances such as gum and candy are molded using the above-mentioned apparatus, the gum is surrounded by the rectangular shape, and high pressure is generated inside the rectangular shape. If the gum protrudes from the gap between the flanged roller and the other roller, the formed shape will bulge out in the form of small protrusions on both ends of the sheet width, and if the viscosity of the gum and rolling speed are not balanced, problems may occur during rolling. Due to the high rolling pressure in the direction of both ends of the gum, the shape after aging was thick at both ends of the sheet width and thin in the center.

The present invention was made in order to solve the above-mentioned problems, and it increases the utilization rate of rolled gum, etc., and forms a rolled gum having a uniform density over the entire width direction of the rolled sheet gum. The purpose of the present invention is to provide a molding device for high viscosity confectionery.

(Means for Solving the Problems) The above object is to provide a lower rolling roller, in which cylindrical rollers that rotate in opposite directions are arranged vertically, and a high-viscosity material is passed between the upper and lower rollers for rolling. , comprising a horizontal rolling roller that rolls the high-viscosity material from both lateral ends of the pressure contact portion of the upper and lower rolling rollers, and characterized in that the horizontal rolling roller is rotated at a slightly faster speed than the upper and lower rolling rollers. This is achieved by a high viscosity confectionery forming equipment.

(Example) An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is an explanatory external view of the apparatus according to the present invention, and FIG. 2 is an explanatory side view of the apparatus according to the present invention arranged in multiple stages in series.

In these diagrams Cζ, (1) is gum (
(hereinafter referred to as gum), (la) shows the form before being rolled with the rolling forming device according to the present invention, and (1b) shows the form of the gum rolled with the device.

Although these gums are not shown, they are placed on a plate wider than the width of the gum and are transported in the direction of the arrow in the figure.

(3) and (4) are cylindrical upper and lower rolling rollers, which are rotated at the same speed in opposite directions via four motors (not shown) and reducers, and are rotated at the same speed in opposite directions by this rotational force while rolling the gum. It is transferred in the direction shown.

The lower rolling roller (4) is installed so that its circumferential top surface is approximately flush with the plate surface, and the lower rolling roller (3) is equipped with springs, hydraulic pressure, etc., although not shown. The pressing means serves as a mechanism for absorbing the upward repulsive force of the gum during rolling. Moreover, the upper and lower rolling rollers (3)
In (4), one or both surfaces are knurled, and the gum or the like is rolled while being bitten into the gap (5) between the upper and lower rolling rollers.

(6a) (6b) is during rolling with the upper and lower rolling rollers,
A horizontal rolling roller that rolls the gum [1a] protruding from the gap from the lateral direction and arranges the residual strain stress of the gum (1b) after rolling in the rolling direction, and the upper and lower rolling rollers (3) (4) Consisting of rollers that are provided at both lateral ends of the gap (5) and are made of discs that are thicker than the thickness of the gap. And the horizontal rolling roller (6a) (6
In b), the upper and lower rolling rollers (3) are rotated in opposite directions to roll and transfer the gum in the rolling direction.
4) Rotate at a slightly higher speed and roll the gum in such a way that both ends of the gum being rolled stick to the horizontal rolling roller.

In this way, by rotating the horizontal rolling rollers (6a) and (6b) at a slightly higher appropriate speed, the amount of the gum (1a) before rolling that protrudes to both ends due to rolling can be adjusted appropriately. 6a) In (6b), rolling is performed, and the discharge amount can be adjusted so that the density is equivalent to the rolling density in the central part.

Next, its operating state will be explained based on FIGS. 1 and 2. Although not shown, the gum discharged from the nozzle of the extruder, which has a rectangular cross section, is sent onto a plate placed in front of the extruder, and is passed through the rolling forming device according to the present invention in multiple stages, as shown in FIG. A gum sheet (1b) having the desired thickness can be obtained.

That is, in each stage, upper and lower rolling rollers (3) (4
) is rotated to transport the gum base (1a) in the direction shown, and at the same time, by passing through the gap (5), the thickness of the gum is reduced while compressing the gum to a constant density. During this rolling, the gum tries to escape to the side with less pressure, but in the center of the width of the rolled sheet, both sides are surrounded by sticky gum, so a certain residual stress arrangement occurs in the rolling direction. Become.

The gum (1b) rolled at both ends of the upper and lower rolling rollers (3) (4) tries to escape toward both ends due to the rolling pressure, but the gum (1b) that is rolled at both ends of the upper and lower rolling rollers (3) (4) tries to escape toward both ends. Since the rolling rollers are arranged so that they rotate at a slightly higher speed than the upper and lower rolling rollers (3) and (4), the rolled gum (1b) is transferred to the horizontal rolling roller (6a). In (6b), the upper and lower rolling rollers are rolled straight in the rolling direction without pecking, and the rotational speed of the horizontal rolling rollers is set to an appropriate rotational speed in relation to the viscosity of the material to be rolled. (3) The gum density at both ends of (4) can be made equal to that of the central rolling part, and the residual strain stress can be arranged in the same direction.

Although gum has been described in this embodiment as the material to be rolled, it is not limited to strain (it goes without saying that it can also be applied to candy, resin, etc.).

(Effects of the Invention) As described above, the present invention provides an apparatus for forming a high-viscosity material into a sheet form, including a set of upper and lower rolling rollers and the first lower rolling roller that rolls the high-viscosity material from the lateral direction into the gap between the rolling rollers. To provide a forming device which uniformly rolls a rolled sheet over the entire area by disposing horizontal rollers rotating at a speed faster than the rotational speed of the rolled sheet on the left and right sides, and has a high production utilization rate of the rolled sheet. I can do it.

In addition, since the rolled sheet is rolled uniformly over the entire area,
This eliminates the conventional work of cutting both sides of a rolled sheet and manually feeding it into an extruder in order to reuse it, and the pre- and post-processes can be automated, resulting in greater labor-saving effects.
