Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 and FIG. 2, reference numeral 1 denotes an apparatus main body, on which a disk-shaped hot plate 2 is installed. The hot plate 2 is appropriately heated by heating means.

A transfer arm 3 is swingably attached to the apparatus main body 1 via a support shaft 4. A swing lever 5 is attached to the end of the support shaft 4, and is connected to a crank 7 via a connector 6. The crank 7 is intermittently rotated by a step motor 8.

A drive motor 9 is installed on the base end of the transfer arm 3, and a transmission shaft 11 is provided via a speed reducer 10.
Is designed to rotate. The transmission shaft 11 extends along the upper surface of the transfer arm 3 to the tip thereof. A bevel gear 12 is attached to the tip of the transmission shaft 11.

As is clear from FIG. 3, the tip of the transfer arm 3 is orthogonal to the transmission shaft 11,
The revolution shaft 13 is rotatably provided. The revolution axis 13
A bevel gear 14 is attached to the upper end of the bevel gear 12 and meshes with the bevel gear 12.

At the lower end of the revolution shaft 13, the revolution arm 1 is provided.
5 is attached so that it can rotate (revolve) integrally with the revolution shaft 13. A rotation shaft 16 is rotatably attached to both ends of the revolution arm 15. The rotation shaft 16 extends downward, and a cloth-drawing spatula 17 is fixed to the lower end of the rotation shaft 16.

A screw gear 18 is fixedly attached to the lower side of the tip of the transfer arm 3. The screw gear 18
A through hole 18a is formed in the center of the through hole 18a, and the revolution shaft 13 is inserted through the through hole 18a. The revolution axis 1
The central axis of 3 and the central axis of the screw gear 18 coincide with each other.

Reference numeral 19 denotes an intermediate transmission shaft, which is rotatably attached to the revolution arm 15 by appropriate bearing means (not shown). A screw gear 20 is attached to the intermediate portion of the intermediate transmission shaft 19, and the fixed screw gear 1 is attached.
Meshed with 8. Worms 21 are attached to both ends of the intermediate transmission shaft 19 and mesh with a worm wheel 22 attached to the upper end of the rotation shaft 16. Reference numeral 23 is a switch lever.

Next, the operation of the apparatus of the above embodiment will be described. As indicated by a phantom line in FIG. 2, the stepping motor 8 is actuated to swing up the feeding arm 3 to heat the hot plate 2 while the dough-spreading spatula 17 is pulled up from the hot plate 2.

When the hot plate 2 is sufficiently heated,
As shown in FIG. 4, the crepe dough M is manually put into the center of the hot plate 2.

Then, when the switch lever 23 is operated, the step motor 8 works again, and as shown by the solid line in FIG. 2, the transfer arm 3 is swung down, and the dough-spreading spatula 17 is placed on the hot plate 2. Set to.

When the cloth spreading spatula 17 is set, the drive motor 9 operates to rotate the transmission shaft 11. The rotation of the transmission shaft 11 is transmitted to the revolution shaft 13 via the bevel gears 12 and 14 and causes the revolution arm 15 attached to the lower end of the revolution shaft 13 to revolve.

Along with the revolution of the revolution arm 15, the screw gear 20 provided on the intermediate transmission shaft 19 revolves around the screw gear 18 that meshes therewith. Since the screw gear 18 is fixed to the transfer arm 3, the screw gear 20
When the orbits revolve around them, as a result, a rotational force is generated in the screw gear 20.

When the screw gear 20 rotates, the intermediate transmission shaft 19
The worm 21 is rotated via the worm 21, and the worm wheel 22 meshing with the worm 21 is rotated. The worm wheel 22
When rotating, the spatula 17 for stretching the material is passed through the rotation shaft 16.
Rotates. In addition, as shown in FIG.
And B indicates the direction of rotation of the spatula 17 for stretching the material. In addition, the dough-spreading spatula 17 is in a state where the stretching start positions are substantially parallel to each other as shown by the solid line state,
The extension end position is in a substantially straight line like an imaginary line in which the extension end position is rotated by approximately 90 °.

In this embodiment, as shown in FIG. 4, the direction of the teeth of each gear is changed so that the rotation shaft 16 rotates 90 ° in the arrow direction B while revolving in the arrow direction A for several revolutions. Set the number of teeth. In particular, by setting the ratio of the worm 21 to the worm wheel 22 to, for example, 1/20 to 1/40, the rotation number for 5 to 10 revolutions is greatly reduced to 90 °. However, in this case, the gear ratio of the bevel gears 12 and 14 is set to 1, and the screw gear 20 makes one revolution while the screw gear 20 revolves around the screw gear 18 once.

FIG. 5 shows another embodiment. A worm wheel 24 'is arranged so as to sandwich the fixed worm 18' from both sides, and this rotation is externally transmitted via each intermediate transmission shaft 25. It is configured such that it is transmitted to the bevel gear 26 at the end portion, and further, the dough-spreading spatula 17 is rotated via a bevel gear 27 provided at the upper end of the rotation shaft 16.

FIGS. 6 and 7 show still another embodiment, in which the intermediate transmission shaft 28 is arranged orthogonal to the transmission shaft 11 and parallel to the revolution shaft 29, and the intermediate transmission shaft 28 is The bevel gear 30 provided at the lower end is the bevel gear 1 of the transmission shaft 11.
Bite to 2. Spur gears 31 and 32 are provided on the intermediate transmission shaft 28.

A spur gear 33 provided on the revolving shaft 29 meshes with the spur gear 31. Since the revolution arm 15 is attached to the lower end of the revolution shaft 29, when the spur gear 33 rotates, the revolution arm 15 rotates integrally (revolution).

A spur gear 34 is meshed with the spur gear 32. The spur gear 32 is attached to the upper end of an intermediate transmission shaft 35. A lower part of the intermediate transmission shaft 35 penetrates the revolution arm 15 and a gear 36 is attached to the lower end thereof.

At both ends of the revolving arm 15, upper ends of the spinning shafts 16 of the cloth stretching spatula 17 are rotatably attached. A gear 37 is attached to each of the rotation shafts 16, and a toothed belt 38 is hung between the rotation shaft 16 and the gear 36.

Since the apparatus of this embodiment is constructed as described above, for example, if the spur gear 31 has thirty teeth and the spur gear 32 has thirty teeth, the revolution shaft will be described. 31: 30: 30 between 29 and the rotation axis 16
÷ 31, that is, a differential of approximately 1.033: 0.967 occurs. As a result, the revolution shaft 16 makes one revolution with respect to the revolution of the revolution shaft 29 about 15 revolutions. Therefore, the 90 ° rotation of the cloth stretching spatula 17 integrated with the rotation shaft 16 is a revolution of 15/4, that is, about 3.75 rotations.

[0027]

The crepe dough is thinly stretched by rotating the dough-spreading spatula while revolving at a position eccentric from the center of the hot plate, so that the creep can be efficiently baked in a hand-baked style.
