DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the outline of a crepe dough stretching device of the present invention. 2 is an enlarged perspective view of the spatula portion, FIG. 3 is a side view of the spatula portion, FIG. 4 is a plan view showing the movement of the spatula when the crepe cloth is stretched, and FIG. 5 shows details of the control means of the spatula drive system. It is sectional drawing shown.

As shown in FIG. 1, this apparatus is provided with a spatula 2 on a hot plate 1 for stretching a crepe dough that revolves while revolving. When the crepe dough is placed on the hot plate or the baked crepe is removed, the stretching spatula 2 can be released upward by rotating the arm 3. Revolution arm 4 to the tip of support arm 3
Is provided and is rotated by a drive mechanism described later to revolve the stretching spatula 2. The mechanism for rotating the stretching spatula 2 will also be described in detail later. This rotation is slower than the revolution, and is approximately 70 ° during 5 to 10 revolutions.
The extent to which the rear of the orbital direction rotates toward the center of the inside.

The structure of the spreading spatula 2 is such that the crepe dough contact portion 5 is chamfered, as seen in FIGS.
The chamfering is performed not only on the tip of the contact portion but also on the bent portion where the thickness of the upper portion is gradually reduced. In order to prevent sticking of the crepe cloth, the material of the stretching spatula 2 is made of fluororesin Teflon in this example, and a channel steel reinforcement 6 is provided on the upper part thereof. The reinforcing material 6 also serves to adjust the weight. It is also possible to use a steel material coated with a fluororesin. The stretching spatula 2 is inclined so that the crepe cloth contact portion 5 is located rearward in the traveling direction. As a structure therefor, the bracket 7 for holding the stretching spatula 2 pivotally supports a bracket piece 7a attached to the spatula rotation shaft 8 and a fixing piece 7b of the stretching spatula 2 by a pin 9, The tilting of the spreading spatula 2 is possible. As shown in FIG. 3, the inclination of the stretching spatula 2 is about 60 to 80 ° with the hot plate.
The angle between the crepe dough contact portion 5 and the hot plate is about 15 °. Since the bracket piece 7a and the spatula rotation shaft 8 are connected through the magnet 10, the stretching spatula 2 can be simply removed by removing the stretching spatula 2.
Can be cleaned.

When the crepe dough on the hot plate is stretched by a stretching spatula that revolves while revolving,
When the crepe dough has been unfolded, it is necessary to return the stretching spatula to its original angle. To that end, I proposed the Japanese Patent Application
In the device of 7-139887, the revolution and the rotation were reversed by rotating them in reverse. For example, in the case of a device in which the revolution axis rotates 90 ° while the revolution axis rotates 10 times, the revolution axis is reversely rotated 10 times to return the rotation axis to the original position when the crepe dough has finished developing. This point was a bottleneck in improving efficiency. Therefore, in the present invention, a control means for separately controlling the rotation axis and the revolution axis is provided.

As an example of the control means for separately controlling the rotation and revolution of the stretching spatula 2, in the example of FIG. 5, a rotation motor 11 and a revolution motor 12 are provided in the support arm 3 and they are connected to each other. The bevel gears 15, 16, and
It was connected by 17,18 and rotated. Rotation axis 1
Reference numeral 3 is inside the double shaft, and a pulley 19 is provided at the inner lower end of the revolution arm 4. This pulley 19 is connected by a timing belt 21 to the upper pulley 20 of the spatula rotation shaft 8 described above. The revolution arm 4 is fixed to the revolution shaft 14 outside the double shaft. Since the rotation motor 11 and the revolution motor 12 are provided independently of each other, by appropriately rotating them, as shown in FIG. The rear of the orbiting spatula 2 in the direction of revolution is almost
It is possible to control the rotation shaft to rotate inwardly about 70 °. The reason for controlling in this manner is to make the crepe dough have a uniform thickness while unfolding and to bring the crepe dough toward the center side to secure a predetermined thickness. Further, after the crepe material is unfolded, it is possible to immediately return the original spatula 2 to the original angle by rotating only the rotation motor 11 in the reverse direction.

FIG. 6 shows another structural example in which the rotation shaft 13 and the revolution shaft 14 are separately controlled. In this example, the revolution motor 12 is provided in the support arm 3, and the rotation motor 11 is provided in the revolution arm 4. Since the revolving arm 4 is fixed to the revolving shaft 14 which rotates by the revolving motor 12, since the spatula 2 is provided on the spatula rotating shaft 8 mounted on the revolving motor 11, the revolving shaft 4 is rotated. By freely rotating the motor 11 and the revolution motor 12, it is possible to freely control the revolution and rotation of the stretching spatula 2 described above, and to return the stretching spatula 2 to the original angle. You can also

In the example of FIG. 7, as a control means for separately controlling the rotation and the revolution of the stretching spatula, the rotation drive of the rotation shaft 13 and the revolution shaft 14 is performed by a common motor 22 and a common shaft rotated by the same.
I am going to do it at 23. Also in this example, the rotating shaft 13 and the revolving shaft 14 are double shafts, and the rotating gear B2
4 and the revolution gear B25, the rotation gear B24 is the common shaft 23
The revolving gear B25 meshes with the revolving gear A26 provided through the one-way clutch 28. The point that the revolution arm 4 is fixed to the revolution shaft 14 is the same as the above example. Stopper 3 for revolution gear A27
0 is provided, and the solenoid 29 can stop only the revolution gear A27 from rotating. The rotation of the spatula rotation shaft 8 is caused by the crank 31 provided between the spatula rotation shaft 8 and the rotation shaft 13. The crank 31 connects a connecting rod 32 provided on the rotating shaft 13 and a connecting rod 33 provided on the spatula rotating shaft 8, and the turning radius ratio (length ratio) of the connecting rod 32 and the connecting rod 33 is arbitrary. The rotation of the stretching spatula 2 can be set to an appropriate angle by setting to.

After the crepe dough has been developed, the motor
By rotating 22 in the reverse direction, the spatula 2 for stretching can be immediately returned to the original angle. OF solenoid 29
When the stopper 30 is engaged with the revolving gear 27 when set to F, the one-way clutch 28 exists, so that even if the common shaft 23 rotates and the rotation shaft 13 rotates in the reverse direction to restore the drawing spatula 2, Since the stretching spatula 2 does not revolve, the spatula 2 can be restored in a short time and the work efficiency can be improved. The revolution gear 27 may be turned on and off by directly engaging the operating rod of the solenoid with the revolution gear, or by engaging the ratchet gear.
