Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to a devanner that separates and conveys flat dough such as pizza dough on a top plate from the top plate.

[Conventional technology]

Flat dough such as pizza dough is roasted on a baking tray, then decorated and baked in an oven. However, in recent years, with the development of refrigeration technology, it has come to be shipped in a roasted state without being fired or in a frozen state after being fired. At this time, the work of separating the roasted or baked flat dough from the flat plate is done manually because the dough is soft and flat.

[Problem that the invention seeks to solve]

However, there is a problem in that it takes time to manually separate a plurality of flat pieces of dough lined up on one top plate, making it impossible to increase the amount of dough produced. Further, when the dough is separated from the top plate, the dough is soft and flat, so the formed or baked shape tends to collapse, resulting in a decrease in commercial value.

[Means for solving problems]

In view of the above circumstances, this invention has a technical problem of automatically separating the flat dough from the top plate without manual intervention. A top plate transport conveyor, a dough transport conveyor positioned above the top board conveyor to transport the flat dough separated from the top board, and a dough transport conveyor that has a suction chamber inside and communicates with the suction chamber on the bottom surface. It has a suction cup, and further,
A chamber that can be raised and lowered from a fixed position to move toward and away from the top plate conveyor, and that can be moved above the fabric conveyor located in front of the fixed position, and a suction chamber and a suction port of the chamber. It consists of a suction blower that is connected via a flexible duct and has a damper that can be opened and closed on its exhaust port side.

[For production]

- According to the above means, after the flat fabric on the top plate of the top plate conveyor descends from a fixed position and is adsorbed by the suction cup of the chamber whose suction chamber is reduced in pressure by the suction force of the suction blower, This chamber rises to its normal position again and then moves forward, thereby being moved above the fabric transport conveyor. Then, the damper is closed and the suction force of the suction blower is extinguished, so that the suction chamber approaches atmospheric pressure, so that the flat fabric that has been suctioned by the suction cup falls onto the fabric conveyor and is conveyed.

Thereafter, the chamber retreats to the regular position and repeats the same operation as described above, and the flat dough is automatically separated from the top plate and transferred onto the dough transport conveyor. The top plate from which the flat dough has been separated is conveyed as is by the top plate conveyor.

〔Example〕

Embodiments of this invention will be described below based on the drawings.

A depanner 1 according to an embodiment of the present invention is shown in FIGS. 1 and 2.
As shown in the figure, the main components include a top plate conveyor 2, a fabric conveyor 3, a chamber 4, and a suction blower 5.

The top board conveyor 2 is for transporting a top board 7 on which a flat dough 6 such as roasted or baked pizza dough is placed. The dough conveyor 3 is installed so as to be located in front of the top plate conveyor 2 in the conveying direction and above the top plate conveyor 2. The dough conveyor 3 and the top conveyor 2 are driven by a motor 9 via a speed reducer 8. The chamber 4 is formed in a box shape with a suction chamber 4a inside, and a connection port connected to the suction port 5a of the suction blower 5 by a flexible duct 10 is provided on the upper surface of the suction chamber 4a. 4b is provided. Further, in the lower surface of the chamber 4, as shown in FIGS. 3 and 4, there are provided a plurality of mounting holes 12 in which female threads 11 are formed concentrically. In these mounting holes 12, bellows-shaped cylindrical suction cups 13 are inserted into the suction chamber 4 of the chamber 4.
It is screwed together so as to communicate with the inside of a. This suction cup 13 is opened when the chamber 4 is lowered.
3 comes into contact with the flat fabric 6, the suction force of the suction blower 5 attracts the flat fabric 6 and separates it from the top plate 7. The upper part of the chamber 4 configured in this way is attached to a rodless cylinder 14, and by the operation of this rodless cylinder 14, the upper part of the chamber 4 is placed above the top conveyor 2 at the fixed position A, and the dough is conveyed. It is configured to reciprocate between a position above the dough transport conveyor 3, which is a front position B in the transport direction of the conveyor 3. This rodless cylinder 14 has a guide frame 15 fixed to the front and rear ends of the top plate conveyor 2 in the conveying direction.
A guide frame 16 fitted so as to be able to freely slide upward and downward.
is fixed.

Since this guide frame 16 is connected to an elevating cylinder 17, it moves the chamber 4 up and down in a reciprocating manner between the upper limit position A and the lower limit position C close to the top conveyor 2. .

A damper 18 is provided on the exhaust port 5b side of the suction blower 5, which connects the suction port 5a and the connection port 4b of the chamber 4 with a flexible duct IO.
By opening and closing, suction force is generated or eliminated in the suction chamber 4a of the chamber 4.

Furthermore, this depanner 1 includes a top plate detector 19 for detecting the position of the top plate 7 transferred by the top plate conveyor 2.
, an upper limit position detector 20 and a lower limit position detector 21 that detect the upper limit position A and the lower limit position C of the chamber 4, and a fixed position detector 22 and the front that detect the regular position A and the front position B of the chamber 4. A position detector 23 is provided, and these detectors detect the position of the chamber 4.
The movement of the damper 18 and the opening and closing of the damper 18 are automatically controlled.

The operation of the depanner 1 of this embodiment having the above configuration will be explained below.

When the chamber 4 is in the fixed position A and the damper 18 is opened, the top plate 7 on which the flat dough 6 is placed
When it reaches a predetermined position by being conveyed by the top plate conveyor 2 and is detected by the top plate detector 19, the lifting cylinder 17 is activated to lower the chamber 4 which is at the fixed position A to the lower limit position C. Then, this chamber 4 is detected by the lower limit position detector 21, and after a predetermined period of time has elapsed, the elevating cylinder 17 is reversely operated and raised to the original position A.

While the elevating cylinder 17 descends and stops for a certain period of time, the flat fabric 6 on the top plate 7 is attracted to the suction cup 13 on the lower surface of the chamber 4 by the suction force of the suction blower 5. Next, when the upper limit position generator 20 detects the chamber 4 which has risen and returned to the home position A, the loftless cylinder 14 is actuated to advance the chamber 4 to the forward position B. Upon detection by the front position detector 23, the damper 18 is closed and the chamber 4 is closed.
The suction force is eliminated, and the flat fabric 6 adsorbed by the suction cup 13 is dropped onto the fabric conveyor 3, and then the chamber 4 is retreated and moved to the original fixed position A. The flat dough 6 dropped onto the dough transport conveyor 3 is transported as it is to the next process. When the fixed position detector 22 detects that the chamber 4 has retreated to the fixed position A, and the top plate detector 19 stops moving the top plate 7, the damper 18 is opened and the chamber 4 The suction chamber 4a is depressurized. By repeating these operations, the flat dough 6 on the top plate 7 of the top plate conveyor 2 is transferred to the dough conveyor 3.
It will be transferred to.

〔Effect of the invention〕

As is clear from the above explanation, since the flat dough can be separated from the top plate using suction power and automatically transported, it is easy to increase the production volume without the need for manpower. In addition, since the flat fabric is evenly adsorbed, the shape of the flat fabric is not distorted, and the incidence of defective products can be reduced, leading to a reduction in cost.
