Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used in a food processing factory or the like, for example, in a sheet form of seaweed rolled.
The present invention relates to a long sheet-like food supply device that is used when continuously performing required processing such as meat, roasted eggs, and vegetables on a belt conveyor, for example, laver rolling processing. It is a thing.

[0002]

2. Description of the Related Art Conventionally, in the food processing industry, when a filling material is supplied to sheet-like food such as plate laver and processed into a scroll, after the filling material is supplied, a belt is rolled by a guide member,
A semi-continuous molding device has been developed, but it has a drawback that it is not suitable for mass production because it is a badge type processing. Therefore, in order to improve the productivity, a conveyor type processing apparatus has been proposed which can continuously perform processing for a long time.

[0003]

In this case, a long sheet-shaped food which is rolled in advance is fed at a constant speed onto a belt conveyor, but the food is fragile such as seaweed,
If the food is easily damaged, if the food supply direction shifts to the left or right with respect to the belt conveyor transfer direction, it is difficult to correct the trajectory of the food by a guide member or the like.

The present invention has been made in view of the above circumstances, and its purpose is to provide a long sheet-like sheet for a belt conveyor while avoiding damage to food by a relatively simple mechanism. The present invention aims to provide a feeding device configured so that the feeding direction of the food can be corrected. The other object of the present invention will be described in detail in the following embodiments.

[0005]

Therefore, in the present invention,
While transferring a long sheet-like food on a linearly extending belt conveyor, when performing a predetermined processing, in the sheet-like food supply device for the belt conveyor, located on both sides of the belt conveyor , Arranging a sensor for detecting the edge of the sheet-like food conveyed on it, and providing a rolling roller for pressing the sheet-like food on the belt conveyor, which is located at the carry-in part of the belt conveyor,
There is provided control means for rotating the rotation axis of the rolling contact roller back and forth on the basis of the detection information of the sensor, with reference to a right angle with respect to the conveyance direction. In this case, the control means is a controller that rotates a motor that rotates about an axis perpendicular to the transfer surface of the belt conveyor in both forward and reverse directions at a required angle based on the detection information provided by the sensor. It is preferable that the rolling contact roller is rotatably supported by a roller shaft mounted orthogonal to the output shaft of the motor.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. In this embodiment of the long sheet-like food product according to the present invention, the sheet-like seaweed feeding device basically transfers the long sheet-like food product F on the linearly extending belt conveyor 1, The sheet-shaped food F rolled is supplied to the belt conveyor 1 when a predetermined processing is performed.

Here, sensors 2 and 2, such as photoelectric tubes, which are located on both sides of the belt conveyor 1 and detect the edges of the sheet-shaped food F transported on the belt conveyor 1, are arranged and the belt conveyor 1 is also provided. 1. A pair of left and right rolling contact rollers 3 and 3 for pressing the sheet-shaped food F with appropriate pressure are provided at the carry-in portion 1A, and the rotation of the rolling contact rollers 3 and 3 is performed. Axis to sensor 2, 2
On the basis of the detection information of 1., the control means 4 which rotates back and forth on the basis of a right angle with respect to the transport direction is provided.

In this embodiment, the control means 4 rotates the electric motor 5 such as a stepping motor or a servomotor which rotates about an axis perpendicular to the transfer surface of the belt conveyor 1, the sensor 2, It is a controller that rotates in both forward and reverse directions at a required angle by the detection information given from 2. Further, the rolling rollers 3, 3 are rotatably supported by roller shafts 3A, 3A mounted orthogonal to the output shaft 5A of the motor 5. The sheet-shaped food F sent on the belt conveyer 1 is further formed at this point by being fed with a filling material such as surimi material, and winding the filling into a cylindrical shape.

In such a structure, the sheet-shaped food F supplied onto the belt conveyor 1 is initially transferred to the rolling rollers 3 and 3 whose axes are oriented in a direction orthogonal to the direction in which the food is conveyed by the belt conveyor 1. , Is sandwiched between the upper surface of the belt conveyor 1 and sent at the transfer speed of the belt conveyor 1, but if the transfer direction shifts to the left or right, one of the sensors 2 detects the edge of the sheet-shaped food, This detection information is given to the control means 4. The control means 4 recognizes the meandering of the sheet-shaped food F to the left and right from the given detection information, gives a proper meandering correction signal to the motor 5, and drives it.
The direction of each of the rolling contact rollers 3, 3 is changed to the right and left at a required angle as shown in FIG. 2, for example. As a result, in the direction of the rolling contact rollers 3, 3, a lateral feed component force corresponding to the rolling contact pressure acts, and the trajectory of the sheet-shaped food product in the transport direction is corrected.

In this system, since the rolling rollers 3 and 3 suppress the surface of the food product and generate a component force to the left and right by frictional resistance, if the rolling pressure is set appropriately, seaweed, etc. With regard to the fragile food, it is possible to correct the meandering without damaging it and ensure the continuity of work. Note that the degree of contact friction is determined by the surface condition, material and contact pressure of the belt conveyor 1 and the rolling roller, and these must be taken into consideration. If the frictional resistance is excessive, it causes damage to the food, and if the frictional resistance is small, the width of meandering correction increases,
The accuracy of the subsequent processing is reduced.

In this embodiment, urethane rubber is used on the surface of the belt conveyor 1 and silicon rubber is used on the surface of the rolling roller 3. If the friction between the belt conveyor 1 and the sheet-shaped food F is small and slippery, while the friction between the rolling roller 3 and the sheet-shaped food F is large, the meandering can be corrected smoothly and efficiently.

In the above embodiment, a photoelectric tube is used as the sensor 2, but other non-contact type sensors can be used to detect the edge of the sheet-shaped food. Further, as shown in the figure, the installation locations of these sensors may be a plurality of pairs instead of the left and right pair, and may be set at a position considerably distant from the carry-in section 1A. Further, it is needless to say that the number of the rolling contact rollers 3 may be increased as necessary to narrow the meandering correction width to improve the accuracy of the trajectory correction.
