Description

[Detailed Description of the Invention] This invention relates to a confectionery manufacturing apparatus in which a relatively hard food core such as chestnut is covered with a relatively soft wrapping material such as bean paste.

In the following explanation, chestnuts will be exemplified as a representative of the relatively hard food core, and bean paste will be exemplified as a representative of the relatively soft wrapping material. It goes without saying that the material is not limited to the illustrated materials.

Traditionally, it has been extremely difficult to manufacture confectionery containing chestnuts wrapped in dairy using mechanical equipment because chestnuts are a natural product and vary in size and shape. Until now, all work had to be done manually.

This invention relates to a device for automatically manufacturing such confectionery using a mechanical device, and in particular to a device for properly positioning chestnuts and bean paste. To provide an apparatus which can accurately arrange the arrangement of chestnuts and pods and the amount of filling to be used, and can automatically and continuously carry out the pre-process of forming the confectionery.

Next, the configuration of this invented device will be explained in detail based on drawings showing embodiments.

In FIGS. 1 to 7, 1 is an upper gear body, and 2 is a lower gear body.

The gear body 1 and the gear body 2 are made so that the pitch of the teeth formed on the curved surfaces is equal to each other.

The gear body 1 is fixed to an upper shaft 3, and the gear body 2 is fixed to a lower shaft 4 provided parallel to the shaft 3. Both gear bodies 1,
The shaft 3 is rotated so that the opposing tooth tips of the two teeth are always in substantially opposite contact with each other on their tip surfaces and rotate at the same circumferential speed.
and shaft 4 are driven relative to each other in opposite directions.

5 is a driving motor therefor, and 6 is a chino for related driving.

The gear body 1 is provided with edge plates 7.7 on both sides, and has a tooth width that is shorter than that of the gear body 2, so that the chestnuts thrown in can be positioned approximately at the center of the length of the tooth grooves.

A is a chestnut feeding device, which is provided on the upper part of the gear body 1, and its details are shown in FIGS. 3 and 4.

The chestnuts a fed from the upper part of the supply cylinder 8 are sequentially placed on the rotary plate 9 as the rotary plate 9 rotates.
11. It advances along the circumference and direction while adjusting the position and the front and back spacing according to 12.

When the chestnut a reaches the lower position of the scraping plate 14 of the scraping cylinder device 15, that is, the photoelectric switch 13, the signal instructs the rotary plate driving motor 16 to stop.

The scraping cylinder device 15 performs a scraping stroke using air from a solenoid valve 17. The solenoid valve 17 is operated by a command from a proximity switch 19 activated by a cam 18 on the shaft 3. Since it corresponds to the phase of the tooth grooves, when the scraping cylinder device 15 works to cause the chestnuts to fall from the drop opening 20, the fallen chestnuts are regularly accommodated near the center of the tooth grooves of the gear body 1.

When the scraping cylinder device 15 completes the scraping stroke and returns to the old position, the stop command for the motor 16 is released and the rotating plate 1
9 rotations are performed again.

The pitch advancing speed of the tooth groove on the surface of the gear body 1 and the feeding speed of chestnuts by the feeding device A are adjusted so that the feeding speed of the feeding device A is adjusted to be slightly faster so that the feeding speed of the chestnuts does not run out. The difference caused by this is made to be absorbed by waiting for a period of time due to the rotation plate 9 stopping.

B is a feeding device for bean paste as a covering material, which is installed on the upstream side of the gear body 1.2 in the moving direction of the opposing tooth tips;
Directing the two sides of the chestnut located in the gap formed by the opposing tooth grooves of both gear bodies, that is, two continuous strips a and b separated by a distance approximately equal to the size of the chestnut a. supply

To explain this state with reference to FIGS. 1 and 5, the chestnut a accommodated in the tooth groove of the gear body 1 moves while being prevented from falling by the fall prevention plate 21, and when it passes the fall prevention plate 21. It is automatically transferred to the tooth groove of the gear body 2 by gravity.

At the same time, the two band-shaped gb and b are cut by the tooth tips of both gear bodies 1 and 2 to become a pair of fragments b/ and b/, and the chestnut a
is placed between the two bean paste pieces b/, b/ in the tooth groove of the gear body 2, and guided toward the next process as the gear body 2 rotates. .

Reference numeral 22 denotes a follower frame, which is loosely fitted onto the shaft 4 and is attached to the gear body 2 so as to straddle it, and performs rotational interlocking with the axis of the shaft 4 as a common axis. It does not have a restraining means such as a key that forces the rotation directly, and the rotation is only performed when the clutch 30 is in the engaged state, and the shaft 4 is rotated via the clutch 30.
When the clutch 30 is in the disengaged state, the rotation is restrained by the cylinder 33.

A cylinder 24 for moving the upper die 23 up and down is provided on the upper surface of the follower frame 22, a side plate 25 is attached to the outside of one side, and a cover plate 26 is attached to the inside of the other side.

The details of these structures will be explained with reference to FIGS. 1, 2, 6, and 7. The side plate 25 has an upper mold 2.
A cylinder 27 equipped with a brush at the tip for cleaning the inner surface of the chestnut a and two pieces of bean paste b/,
A cylinder 28 equipped with a pressing disk at its tip for press-forming b / toward the lid plate 26 in one stroke in the cylindrical chamber formed by the lowering of the upper die 23.
and a cylinder 29 equipped with an extrusion plate at its tip for extruding the molded confectionery laterally from the tooth groove to the outside.
and are attached respectively.

It is more preferable that the extrusion plate is provided with a brush that can clean the inner surface of the tooth groove during the backward stroke.

The relative positions of the above three cylinders are as shown in FIG. On the other hand, the cylinder 27 is the upper mold 23 when the upper mold 23 is raised by the cylinder 24.
is located at a radial distance that coincides with the inner surface of .

The cylinder 29 is on a phase q that is advanced by one pitch of the teeth of the gear body 2 with respect to the phase p, and is located at a radial distance that matches the tooth groove of the gear body 2.

The clutch 30 is located on @4 as shown in FIG. 2, and is used to engage and disengage the shaft 4 and the follower frame 22 in conjunction with each other.

The above-mentioned fitting/disengaging command is sent by the cam 31 on the shaft 3 and the proximity switch 32 in contact with the cam 31, and the upper die 23
The cam 31 is configured so that the clutch 30 is brought into the engaged state at a position where the tooth grooves of the gear body 2 and the tooth grooves of the gear body 2 exactly match, and then the clutch 30 is brought into the disengaged state.

33 is a return cylinder whose tip is pivoted on the side plate 25, and after the follower frame 22 is engaged by the clutch 30 and moves together with the gear body 2 within a predetermined range, the clutch 30 is released. This is to return the following frame 22 in the opposite direction by -pitch when the condition is reached.

In FIG. 1, when the tracking frame 22 moves together with the gear body 2 from the p phase to the q phase, the cylinders 28 and 29 operate simultaneously during the movement,
The actuation of the cylinder 28 causes compression molding of the confectionery as shown in FIG. 7, while the actuation of the cylinder 29 simultaneously performs an extrusion operation on the confectionery that has already been formed and is located in the tooth groove preceding the pitch; The inner surface of the tooth groove is cleaned.

When both of the above operations are completed, the follower frame 22 has moved from the phase p toward the phase q, and therefore the extrusion cylinder 29 has moved from the phase q toward the phase q'.

When the clutch 30 is disengaged, the linkage between the shaft 4 and the follower frame 22 is released, and at the same time, the follower frame 22 is moved in the opposite direction by -pitch by the cylinder 33, and in the meantime, the follower frame 22 has already been pulled up by the cylinder 24. upper mold 2
3 is cleaned by the cylinder 27, and at the end of the movement of the follower frame 22 in the opposite direction, the upper die 23 is pushed down by the cylinder 24, and the bottom surface becomes the inner surface of the cover plate 26 between the corresponding tooth grooves. A cylindrical chamber is formed (FIG. 6).

FIG. 8 shows the above-mentioned related operations as a time chart.

In the figure, the time required for one tooth of the gear body 2 to rotate is taken as a unit of cycle, the horizontal axis shows the passage of time, and a preferable example of the start and end of each operation is displayed.

The settings for each of the above starting and ending times can be set using the proximity switch 3-2.
An easy-to-understand method is to use a timer to regulate the timing of each operation, but another method is to install a cam etc. on the rotating shaft and mechanically regulate these based on the rotational phase. Of course, it is also possible.

By sequentially repeating the above series of operations, the desired confectionery is continuously molded, and the cylinder 29 moves the gear body 2
The confectionery pushed out through the tooth grooves is guided to the gutter 34 and falls, but at this time, a pair of finishing rolls rotate in the same direction and are arranged so that the rotation speed of each can be adjusted individually. By passing through the gaps 35 and 36, the entire circumferential surface is evenly rounded and the outer shape is finished.
Thereafter, it is placed on a conveyor belt 37 and transported.

Among the above-mentioned series of manufacturing devices, the device of the present invention is designed to insert a predetermined amount of bean paste into the tooth grooves formed on the surface of the gear body 2.
, b / and one chestnut interposed therebetween in a continuous and regular manner, and relates to a device for performing the first half of the series of manufacturing devices described above.

Since the device of the present invention is constructed as described above, the placement of chestnuts and filling as well as the proper arrangement of the amount of filling to be used can be accurately performed with a simple device, regardless of the size or shape of the chestnut, and the confectionery can be formed. This has the advantage that the first half of the operation can be performed automatically and continuously.
