Description

  The present invention relates to a feeder that supplies a material to be supplied (for example, tablets, capsules, etc.), and a counting filling machine including the feeder.

  As a method of supplying a supply such as a tablet or a capsule with a rotary feeder, the feeder rotates around a vertical axis or close to the vertical axis to supply the supply, and a rotation around a horizontal axis. There is a method of supplying a material to be supplied.

  As a method of rotating and supplying around the vertical axis or close to it, for example, a base having a tablet discharge port, and provided on the base so as to be rotatable via a driving means, and a notch along the outer periphery. An automatic high-speed counting device (see, for example, Reference 1) composed of a separation feeder formed with a cylindrical tablet hopper connected to a base so as to surround the separation feeder, and a rotor on the inner bottom portion is rotatable A built-in tablet storage case and a support base that supports the motor for driving the rotation of the rotor are detachably mounted, and a plurality of pockets for storing tablets are provided at predetermined intervals between the outer periphery of the rotor and the inner bottom. A tablet feeder that allows tablets to be discharged when any of the pockets matches a discharge path provided at a predetermined position (see Reference 2 for example), and sequentially rotates to each pocket formed on the outer periphery. There is a rotation device at the center as in the method of supplying the tablet with a tablet aligner that holds the agent and discharges it at the discharge position (for example, see Reference 3), and the tablet is aligned on the outer periphery by the rotation device, A method of supplying to the outside, and a rotating disk provided with a rotating disk provided with a plurality of tablet measuring holes in a circular shape centered on the rotation center provided to rotate about an axis inclined with respect to the vertical There is a method of aligning the tablets by rotating them and discharging them to the discharge holes on the outer periphery (see, for example, Reference 4).

  In addition, as a method of supplying an article to be supplied by rotating around a horizontal axis, a packaged article such as a tablet is sucked and held on the outer peripheral surface of the charging drum in a state of protruding from the outer peripheral surface of the drum. And a method of supplying a tablet (see, for example, Reference 6) having a pocket aligned on the drum surface and installing a tablet in the pocket. is there.

The method of supplying the supply object by rotating around or close to the vertical axis is likely to contact the rotating part of the supply object or the periphery thereof and cause cracking or chipping. Therefore, a means for preventing them is provided, but it is not sufficient. In addition, the amount of supplies that can be filled at a time depends on the area of the rotating surface, and cannot be so large in terms of installation. On the other hand, the conventional method of rotating around the horizontal axis and supplying the material to be supplied is less likely to break or chip, but it is stored in a pocket. Therefore, there is a disadvantage that the entire apparatus becomes complicated and control is difficult.

  Furthermore, the present invention is characterized in that the material to be supplied is fed from the center of the feeder side surface, and the drum rotates in the circumferential direction using the centrifugal force generated by the rotation of the feeder during discharge, and is discharged from the discharge port. A method for supplying a material to be supplied is provided.

  According to the present invention, there are provided a feeder that is unlikely to be cracked or chipped and that can supply a material to be supplied at high speed, and a counting filling machine that uses the feeder.

  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 shows a configuration example of the counting and filling apparatus of the present invention. In the counting and filling machine 1, a drum-like feeder 5 having a supply outlet 6 regularly arranged along the outer periphery is installed in a feeder rotating device 7, and means for supplying the supply to the feeder 5 is provided. For example, it has a hopper 2, a vibratory material supply machine 3, and a chute 4. One of the chutes 4 extends to the hopper 2, and the other extends to the supply object supply port 12 at the center of the side surface of the feeder 5. The supply discharged from the supply discharge port 6 of the feeder 5 is filled into a container 10 supplied by a conveyor 11 through a counter 8 and a means for filling the container, for example, a chute 9. The

  In the present invention, the circumferential direction refers to a direction that rotates around a vertical axis, a horizontal axis, or a state close thereto, and preferably a direction that rotates around a horizontal axis.

  As shown in FIG. 2, the feeder 5 has a supply outlet 6 regularly arranged along the groove. As shown in FIG. 3, the supply 14 has grooves 15 existing along the outer periphery inside the feeder 5, and aligns the supply. The depth of the groove 15 is such a depth that it is easy for the supplies to be aligned, and is preferably between 0.3 and 2.0 when the height of the supplied supply is 1. More preferably, it is between 0.5 and 1.5. The width | variety of the groove | channel 15 should just be larger than the width | variety of the to-be-supplied object 14, Preferably it is 1-1.5 with respect to the to-be-supplied object 1, Preferably it is 1.1-1.3. Further, as shown in FIG. 3, it is preferable that the heights of the partition of the grooves are alternately combined so that the supply object 14 can easily enter the groove 15, as shown in FIG. 3.
