Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is suitable for packing Fukugami-zuke, chopped vegetables, pickles, meat, feed, chopped vegetables such as glass fiber, or boiled beans, small fish Tsukudani, starch, etc., which are likely to cause entanglement and are entangled. The present invention relates to a supply impeller for continuously and uniformly supplying and dropping the shredded products and the like put into a hopper.

[0002]

[Prior art]

 In the past, a shutter was installed at the drop opening of the hopper into which the shredded material was thrown, the degree of opening of the shredded material was controlled by the degree of opening, and the shredded material was dropped onto the conveyor belt, and the trough of the straight feeder was further vibrated. The crushed pieces are leveled so that an even amount can be conveyed.After the conveyor belt is dropped into a receiving bucket, it is weighed and put into a packaging bag, bottle, etc. for packing. .

[0003]

[Problems to be solved by the device]

 The drop from the drop opening of the hopper is a continuous granular amount such as dried granules, agglomerates, or fresh spherical fruits and vegetables, but sticky and entangled substances are likely to occur, such as Fukugami pickles. In the case of shavings containing water such as the above, they may stick to each other and form lumps that drop intermittently, adhere to the inner wall of the hopper, or bridge and do not fall.

Even if it drops onto a straight-line feeder, uniform continuous feeding is impossible only by the vibration of the trough, and extrusion by a screw causes biting, so that little effect can be expected. Even if the rotating shaft with pins or blades attached is rotated, the chopped objects may get stuck between the pins or blades, or the jammed pieces may drop together, causing a uniform amount to continue. We cannot supply. As a result, the accuracy of weighing the contents of one pack is inferior, and if it falls as a lump, the impact may make the reading of the weighing instrument inaccurate, or the weighing time may vary significantly. At present, we are not satisfied with the measurement accuracy and automation of the entire device.

[0005]

[Means for Solving the Problems]

 Therefore, the present invention does not require a shutter opening adjustable hopper, a straight feeder, a belt type conveying device, a screw device, or the like, and supplies a blade wheel that can be continuously and uniformly dropped.

A conventional impeller has a plurality of blade pieces radially protruding in a direction orthogonal to the rotation axis or has a pin protruding, so that a pair of blades with two rotation shafts is provided. In view of the intermittent and conspicuous and uneven supply of shavings, which is conversely temporarily retained between the pins or between the pins, the present invention is based on the ridgeline of one blade and the other. The blade pillars of each impeller are designed to scrape off the shavings attached to the center of the blade sides and prevent the shavings from accumulating between the blades, and the rotation of both rotating shafts can be synchronized or set arbitrarily. It was made to let.

Therefore, the shape of the impeller is a polygonal column, and the ridgeline of the polygonal column of one impeller is between the center of the side of the polygonal column of the other impeller and the rotation axes of both impellers. Both impellers are rotated so that they meet on the line connecting them.

[0008]

【Example】

 The present invention will now be described with reference to the embodiments shown in the drawings.

FIG. 1 shows a first embodiment.

The supply impellers A and B are arranged close to each other and rotate in opposite directions to each other as indicated by an arrow. The two supply impellers A and B are both regular triangular prisms, and the mutual positional relationship is such that the center of the ridgeline Aa or the side Ab of the regular triangular prism of one supply impeller A is the other. Rotate so as to sequentially meet on the line XX (indicated by a one-dot chain line) connecting the center or the ridgeline Ba of the side Bb of the equilateral triangular prism of the supply impeller B and the rotation axes 1A and 1B of both impellers. To do. The rotation speed of both rotary shafts should be the same or one of them should be an integral multiple of the other.

FIG. 2 shows a second embodiment.

In each of the supply impellers A and B, three equilateral triangular prisms 2 to 7 are connected coaxially 1C and 1D, respectively, and the equilateral triangular prisms are 40 degrees or 80 degrees each. It is fixed in a positional relationship that is offset in the direction of rotation. In FIG. 2, in the supply impeller C, the equilateral triangular prisms 2 to 4 fixed to the rotating shaft 1C are fixed at positions displaced by sequentially rotating in the rotational direction by 40 degrees or 80 degrees, respectively.

In the supply impeller D, equilateral triangular prisms 5 to 7 fixed to a rotation shaft 1D are fixed at positions displaced by sequentially rotating by 40 degrees in the rotation direction.

Since both rotary shafts rotate in opposite directions, the first to third regular triangular prismatic bodies in both supply impellers are arranged in the opposite direction.

The ridge lines of one of the corresponding equilateral triangular prisms 2 and 5, 3, 3, 6, 4 and 7 of the two supply impellers and the center of the other side are on a line XX connecting both rotation axes. Both rotating shafts rotate as if they met in sequence.

FIG. 3A shows a line connecting the ridgeline of the first equilateral triangular prism 2 of the supply impeller C and the center of the side 5b of the first equilateral triangular prism 5 of the supply impeller D between both rotation axes. 3B, the center of the side 3b of the second equilateral triangular prism 3 (indicated by diagonal lines) of the supply impeller C and the second equilateral triangle of the supply impeller D in FIG. 3B. The ridgeline 6a of the column 6 meets on the XX line, and in FIG. 3C, the ridgeline 4a of the third equilateral triangular column 4 (shown in black) of the supply impeller C and the supply impeller D. And the center of the side 7b of the third regular triangular prism 7 meet on the XX line. In this way, the ridgeline of each equilateral triangular prism meets the center of the side, and the corresponding equilateral triangular prism makes 6 encounters each time the rotation axis makes one revolution. Meet once. That is, an encounter is made every 20 degrees of rotation.

It should be noted that, depending on the type of chopped object or the like, it is more effective for the shape of the supply impeller to form each side into a slightly concave or convex curved surface as shown in FIG.

Further, as shown in FIG. 5, the number of regular polygonal columns of the two supply impellers may be different, and one may be a regular triangular column and the other may be a regular quadrangular column. However, in this case, it is necessary to make the rotational speeds of both rotating shafts different. For example, in the case of FIG. 5, the rotation speed of the equilateral triangular prism is set to 4/3 times the rotation speed of the regular quadrangular prism.

[0019]

[Effect of device]

 According to the supply impeller of the present invention, for example, in the case of the second embodiment of the equilateral triangle, the ridgeline of any equilateral triangular prism and the center of the side meet every 20 degrees of rotation. Since it is crushed, the chopped material can be supplied continuously and evenly without sticking and bridging. Therefore, the opening adjustment shutter, the linear feeder, the belt type conveying device, the screw device, etc. are not required, so that the cost is low and the structure is simple, and the supply device is easy to disassemble and clean. Furthermore, because they are arranged consecutively and the polygons of each other are intertwined with each other, the supply wheel is stopped at the same time as the supply is stopped, increasing the amount of stagnation between the blades and pins, and fickle it. Since there is no drop, the weighing accuracy is improved and a stable weighing time can be obtained.
