Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kneading device for kneading food dough, and more particularly to a kneading device for kneading soft biscuit dough made from butter, sugar, flour, eggs and the like. .

[0002]

2. Description of the Related Art Conventionally, most of the kneading work of soft food dough has been done manually, and recently, a method of mechanically kneading them together has been studied. For example, the lower side cut in an arc shape is used. Research and development has been carried out in which the food dough is inserted into the fixed disk and the rotating disk that rotates on it, and the food dough is twisted due to the difference in peripheral speed between the center position and the outer peripheral portion of the rotating disk. .

[0003]

Unlike the mechanical work, the conventional manual lacing work has a large individual difference.
There is a problem that it is difficult to maintain and manage productivity, and in the latter method of causing twist between notched disks, food dough is supplied and carried out from the notched part between two disks. , Feeding and unloading work is difficult, and if the dough is not supplied to the center line of the disc, it will be deformed or twisted, and if the hardness of the dough is not constant, it will affect the quality and cool to a constant temperature. There was a problem that a process was required.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to make a soft and hard-to-process food dough highly efficient without requiring manpower. The present invention intends to provide a device for kneading food dough, which can be kneaded and processed with stable quality.

[0005]

In order to achieve the above-mentioned object, a device for twisting food dough according to the present invention is loosely fitted to a rotary shaft having a spline engraved thereon and slid vertically, and in a lateral direction. One end side is loosely fitted in a rotating spline nut and a rotating disc mounted below the spline nut, and a groove section provided along the outer peripheral surface of the spline nut, and a drive control section is provided at the other end side to form a swinging pivot shaft. And an elevating member by an elevating lever that swings the rotating disc up and down with both ends vertically swinging, a belt conveyor that stops the feeding of the food dough directly below the rotating disc, and a belt conveyor that is placed on the belt conveyor. And an optical sensor that detects that the food dough has reached the center position directly below the rotating disk.

[0006]

The food dough Z, which is kneaded by a device other than the present invention and formed into a rod shape, is vertically stacked on the center line in the width direction of the belt conveyor, and is fed (upper side in FIG. 2). Food dough Z)) The food dough is conveyed under the rotating disk by the belt conveyor, and when the center of the food dough reaches and reaches the center of the rotating disk, the optical sensor detects this and the belt conveyor is driven to rotate. And sends the detection signal to the drive section to stop the conveyor and the detection signal is also transmitted to the drive control section of the lift lever, and the tip of the lift lever is pushed down by the force of the spring of the drive control section to rotate the rotary shaft in advance. The spline nut and rotating disc descend while rotating, and when the rotating disc comes into contact with the food dough on the conveyor, the peripheral speed of rotation of the rotating disc becomes faster toward both ends of the food dough. And, both end portions of the left and right boundary of the center position for rotation in the opposite direction,

The two rod-shaped food doughs that are vertically stacked are twisted together, and after being securely kneaded for a certain period of time set by a timer (not shown), they are urged to the cylinder of the drive control section of the elevating lever. On the contrary, when the spline nut and the rotary disk are raised and then the conveyor is rotated, the kneaded food dough can be taken out while being placed on the conveyor.

EXAMPLES Examples will be described with reference to the drawings. In FIGS. 1 and 2, the rotary shaft 1 is provided vertically above the center position in the width direction of the endless belt conveyor 2 that is transported in the horizontal direction, and is mounted by a bearing so as to rotate in the horizontal direction. . The spline 3 is vertically formed on the outer peripheral surface of the lower end of the rotary shaft 1. The spline nut 4 is formed in a substantially cylindrical shape, and a female side spline that fits into the spline 3 is vertically formed on the inner peripheral surface of the spline nut 4 and is loosely fitted to the spline 3 so as to slide in the vertical direction. The up-and-down groove 5 is formed in a circular shape on the outer peripheral surface of the spline nut 4 by recessing it in a U-shaped vertical section along the outer peripheral surface of the body portion of the spline nut 4.

The rotating disk 6 is fixed laterally with the center of rotation of the spline nut 4 aligned with the lower end of the spline nut 4. The elevating levers 7, 7 forming an elevating member are framed, for example, in the shape of a ladder. The cam followers 8, 8 provided in a direction perpendicular to the conveying direction of the belt conveyor 2 and pivoted inwardly inside each tip (the left end in FIG. 1) are vertically rotated in the ascending / descending groove 5. Thus, the rocking pivot shaft 9 is laterally inserted at a substantially intermediate position of the elevating lever 7, and the front and rear ends of the elevating lever 7 are supported so as to be vertically rockable about the rocking pivot shaft 9.

In the air cylinder 10, a rod 12 of the air cylinder 10 is attached to an elevating shaft 11 which is inserted laterally in the rear end side of the elevating lever 7 and is appropriately attached to a machine frame (not shown) or the like. The lower end of the spring 13 is suspended from the elevating shaft 11, and the upper end is attached to the machine frame. The interval adjusting bolt 14 is attached to the machine frame downward at a position where the upper surface 15 on the rear end side of the elevating lever 7 abuts, and the drive control unit of the elevating lever 7 is connected by the air cylinder 10, the spring 13, and the interval adjusting bolt 14. To form. The optical sensor 16
It is provided on the side surface of the belt conveyor 2, and more specifically, the food dough when the central portion of the food dough Z placed and conveyed on the belt conveyor 2 reaches just below the center position of the rotating disc 6. It is installed on the detection line that detects the tip of Z.

[0011]

As described above, the apparatus for kneading food dough of the present invention only needs to doubly stack and feed the soft food dough kneaded in a rod shape onto the belt conveyor, and after that, the belt conveyor automatically operates. It becomes possible to twist the food dough in the gap between the rotating disk and the rotating disk, and even after it is twisted, the food dough can be picked up by hand as it is on the belt conveyor and bent immediately into various shapes. Since it can be supplied to the process, it becomes possible to automatically twist the soft food dough by machining,
It does not require manpower and contributes greatly to productivity improvement and quality stabilization.
