Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically and continuously filling spheres of the same diameter to a target value with a sphere diameter designated by a host device and a filling weight per carton without a heap on a carton of a fixed size. The present invention relates to an automatic sphere filling device.

[0002]

2. Description of the Related Art An empty carton filled with spheres is transported by a conveyor to a position where the spheres filled by an automatic box making machine are filled. The operator performs rough filling by opening and closing the gate while referring to the weighed value with the standard filling weight per carton as a guide, and finely adjusts several spheres with the operator's hand to a predetermined amount Spheres into an empty carton. The operator delivers the filled cartons onto a conveyor that leads to an automatic sealing machine that seals the cartons. Also,
At the time of filling, the operator records the weighed value of each sphere in the carton, and the total weight of the predetermined carton N cartons = the carton of N cartons within the weight control standard having a certain width with respect to the target weight. The spheres are filled while adjusting the filling weight per carton each time so that the total weight at the time of completion of filling is included.

[0003]

The filling operation involves opening and closing the gate of a hopper in which spheres are accumulated, and filling the cartons with the spheres. However, since the spheres only depend on their natural fall, a heaping state occurs. There is. This heap-like filling state hinders the automatic sealing of the sealing machine. In this case, the sphere in a heaped state is leveled manually by an operator. Also, since the weight error is included in each sphere, the number of spheres to be filled is not uniquely determined,
It is necessary for the operator to take in and out several spheres while looking at the weighed value, and to make fine adjustments. When opening and closing the gate of the hopper, it is difficult to finely adjust the number of spheres to be filled in the carton, and this operation is troublesome and troublesome, and significantly reduces the efficiency.

According to the present invention, based on the sphere diameter specified by the host device and the filling weight per carton, sphere cutting control is performed with the filling weight per carton as a target value,
Without automatically filling a predetermined number of spheres into a heap, the carton is filled automatically and continuously, and the labor of filling manually, finely adjusting the filling amount, leveling, and recording the filling weight per carton is eliminated. An object of the present invention is to provide a sphere automatic filling device which contributes to labor saving and work efficiency.

[0005]

According to the present invention, there is provided an automatic sphere filling apparatus comprising: a supply device for cutting a predetermined amount of spheres from a stagnated sphere array having the same diameter; and a predetermined amount in each stage corresponding to a carton filling state. A plurality of gutter-shaped storage units that stock the spheres, a weighing device that weighs the weight of the spheres stocked in each storage unit, a filling device that fills the spheres one by one corresponding to each stage in the carton filled state, It is characterized by comprising a swinging device for equalizing the filling state of the spheres at the time of filling, and a conveyor for supplying an automatically produced empty carton and conveying the filled carton.

[0006] Based on the sphere diameter specified by the host device and the filling weight per carton, a filling pattern in which the number of spheres to be filled in each stage determined by the diameter of the sphere, the standard weight of the sphere, and the size of the carton is determined. A controller is provided for automatically selecting a sphere for one carton, weighing the weight of the sphere at the stage of preparing the sphere, and controlling the cutting of the sphere with a target filling weight per carton specified by a host device. It is characterized by the following. Further, a sphere prepared in advance for each stage corresponding to the carton filling state is filled for each stage. Further, when the sphere is filled, the sphere is filled while swinging the carton itself.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the automatic sphere filling apparatus of the present invention, the total weight of N cartons is set within a predetermined weight management reference value of the total weight of N cartons by the method of filling spheres of the same diameter. In the weighing control method, the total weight of the carton N cartons and the weight management reference value determined by presetting the weight management reference are set, and the weight is calculated each time the filling device completes filling the carton 1 carton. The arithmetic unit compares the added actual weighing accumulated value with the arithmetic unit, finds the difference, determines the number of spheres to be filled in the next one carton by the arithmetic unit, and cuts out the determined number from the supply unit to the filling unit. In a weighing control method for keeping the total weight of the carton N cartons within the weight management standard,
It can also be used for automatic filling of spheres.
