Description

The present invention relates to a pasta serving device for a bento container, which is necessary for serving pasta in a bento container in a series of work steps of filling a bento container with food.

Conventionally, in the work of serving various foods in a bento container, a part of the food is arranged in a bento container transported by a conveyor belt in a case where the food is arranged by hand in a primitive manner and in a series of flow operations for producing a large amount of bento. Depending on the machine, the necessary food may be served.

In particular, in the work of serving food such as rice and side dishes in a bento container with some serving machines, a special arrangement in which pasta is first laid on the bottom of the bento container and the main bento side dishes are placed on top of it. There is a work style.

However, in the pasta laying work, it is complicated to serve a certain amount of pasta accurately and it is difficult to work with a machine, and only this work form has to be served manually.

In order to mechanize the work form of pasta serving, a plurality of rod-shaped members conventionally arranged in a circle are rotated in an arc toward the center of the circle by using a robot hand mechanism to wind up the linear pasta. The food gripping mechanism configured in the above is disclosed (see Patent Document 1).

However, since this robot hand mechanism is configured to hold linear food such as pasta while rotating and contracting the inscribed circle of the rod-shaped members arranged in a circle toward the center, it is used to prevent drying. The pasta surface-coated with olive oil is slippery at the gripping mechanism portion, and there is a risk that the pasta will be missed while being carried to the position of the lunch container.

In other mechanical devices, a pair of gripping mechanisms formed in a comb shape with a curved central portion are opposed to each other to open and close so that the comb blades can occlude with each other, and linear food such as pasta is placed between the occlusal comb blades. A robot hand device configured to be sandwiched is disclosed (Patent Document 2).

Further, in order to accurately grasp the amount of food gripped by the robot hand device, that is, the amount of food to be served, it is necessary to detect the amount of gripped food, and the detection method is to use a detection plate erected between the gripping members. It is possible to detect the volume of food in contact with the detection plate via vertical movement, that is, when the gripping member grips the food, when the detection plate pushed up by the gripped food rises, the gripping amount can be detected by the rate of increase. ..

However, pasta when pasta is laid lunch container is minor number, in the detection method, there is a possibility not accurately detect the small amount of pasta gripping amount, also gripped by confronting the bent inner side of the comb Since the side of the curved comb blade is open on the opposite side, pasta may leak from the open part and slip off.

Will be described assuming a case where the lunch box T is laid as an underlay and a side dish of a bento container T such that a hamburger is placed on the hamburger steak.

Above the uppermost stream portion of the conveyor belt C, a distribution inclination detection unit 4 is provided to detect the distribution posture of the bento container T.

The distribution inclination detection unit 4 is composed of a detection camera 4a, a calculation means 4b, and an instruction unit 4c. The means 4b calculates the serving position of the bent box container T in the tilted state, and the indicator 4c transmits the tilt information and the serving position calculation information of the bento container T to the winding tool moving mechanism 2. Instruct the pasta serving work of the moving mechanism 2.

As shown in FIG. 3, the distribution inclination detection unit 4 first uses the center line (represented by a single point chain line in the figure) that equally divides the width in the distribution direction of the conveyor belt C as a reference, and the apex a of a substantially rectangular shape of the lunch container T. , B, c, d, which is the four line segments formed by the side ab, the side bc, the side cd, and the side da. It is detected and stored (in the figure, the side ab and the side cd located opposite to the side ab).

Next, the side that is equally divided by the center line and the side that is equally divided by the center line have a common point with either side (in the figure, the line segment related to the center line is the side da, which is common. The point of is detected and stored as the pasta P filling position information by the distance x in the flow direction of the conveyor belt C and the distance y in the direction orthogonal to the flow of the conveyor belt C starting from a).

The above-mentioned normal position information of the lunch container T and the filling position information of the pasta P are stored in advance in the distribution inclination detection unit 4. Then, based on the above two pieces of information, the distribution inclination of the bento container T conveyed on the conveyor belt C and the filling position of the pasta P in the bento container T are calculated.

That is, when the bento container T is image-detected with the detection camera 4a deviated from the normal position as shown in FIG. The distances to the four points a', b', c', and d'of the lunch box container T actually transported are calculated, and the sides a'b', the side b'c', and the side c'd' , A substantially rectangular a'b'c'd'of the lunch box T formed by the line segment of the side d'a'is derived, and the substantially rectangular a'b'c'd' is displaced from the normal position in position and posture. calculate.

Next, the distance x and the distance y from the curved scale hand stored in advance are adapted to the substantially rectangular a'b'c'd'calculated as shown in FIG. 3C, and the calculation means 4d is a lunch box. Even if the container T is displaced on the conveyor belt C, the position and posture of the bento container T and the filling position of the pasta P are accurately calculated.

The inclination information and the serving position calculation information of the bento container T calculated as described above are transmitted to the winding tool moving mechanism 2 by the instruction unit 4c of the distribution inclination detecting unit 4, and the pasta serving of the winding tool moving mechanism 2 is performed.

The pasta stacking detection unit 7 is composed of a laser sensor, which detects the unevenness of the upper surface of the pasta collected in the bowl and transmits the posture information of the laminated pasta to the pasta leveling mechanism 6 and the bowl placement for bowl rotation. It is transmitted to the drive unit 5c of the unit 5 to control the pasta leveling mechanism 6 so that the pasta in the bowl is in a uniform laminated state.

Further, a measuring unit 3 is provided above the pasta winder 1 to measure the amount of pasta wound.

That is, the measuring unit 3 measures and detects the weight of the pasta winder 1 in a state where the pasta is wound and held, and the weight of the pasta winder 1 itself before the pasta is wound is measured as a predetermined weight. It is read in advance in the part 3, and the weight of the pasta winder 1 after the pasta is wound and the weight of the pasta winder 1 itself are compared and calculated to detect the weight of the pasta itself, for example, in the load cell. It consisted of such measuring instruments.

The measuring unit 3 measures the weight of pasta wound by the pasta winder 1, but when the pasta winding amount is large, a constant amount is sent by sending a rotation instruction opposite to the winding operation. The mechanism may be such that the pasta is released until the pasta becomes full, or when the amount of pasta to be wound up is small, the shortage is wound up after the filling of the lunch box T is completed.

The present invention has been described through examples as a lunch box container T filled with pasta, but the one to be wound and filled is not limited to pasta, and any long and thin pasta may be used.
For example, it can be used for udon noodles and soba noodles. At that time, it is preferable to change the shape of the pasta winder 1 such as the size as necessary.
