Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to an article supply device for supplying articles to each weighing hopper or the like in a combination weigher.

<Prior Art> Conventionally, as the above-mentioned article supply device, there has been one as shown in FIG. 6, for example. This consists of a distributed feeder 1 and a plurality of straight feeders 2,
The distribution feeder 1 includes a table 3 configured in a conical shape.
The table 3 is provided with a drive source (not shown) for causing the table 3 to move in a circular motion, a turning motion, a spiral motion, or the like. Each linear feeder 2 is provided with a tray 4 and a vibration source (not shown) that vibrates this tray 4.
The trays 4 are arranged radially around the peripheral edge of the table 3 so that side walls 4a of the trays 4 overlap each other. Although not shown, a weighing hopper or an intermediate hopper of a combination weigher is arranged below the tip of the tray 4 of each linear feeder 2, and receives articles from each linear feeder 2. In this article supply device, when an article is supplied to the top of the table 3 of the dispersion feeder 1, the table 3 is moved in a circular motion, a turning motion, a spiral motion, etc. by the drive source, so that the article is delivered from the top to the periphery. It descends and transfers to each straight feeder 2. Among the linear feeders 2, those whose weighing hopper or intermediate hopper is empty activates the vibration source to vibrate the tray 4 and feed the articles on the tray 4 to the tip side of the tray 4. , from where the goods are fed to a weighing hopper or an intermediate hopper.

<Problems to be Solved by the Invention> In such an article supply device, long, thin and soft articles, such as jelly sweets or pickled cucumbers, may be supplied to each measuring hopper or intermediate hopper. In such a case, when transferring from the table 3 of the distributed feeder 1 to the tray 4 of each linear feeder 2, the article may straddle the side wall 4a of the overlapping trays 4 as shown in FIG. If the articles straddle this part, even the articles moving in the center of the tray 4 of the linear feeder 2 will become stagnant, making it impossible to smoothly feed long, soft articles to each weighing hopper or intermediate hopper, which will reduce assembly accuracy and processing. There was a problem that the ability decreased.

<Means for Solving the Problems> In order to solve the above problems, this invention, like the conventional ones, includes a dispersion feeder having a table configured in a substantially conical shape, and In a distributed feeding device having a plurality of linear feeders arranged radially, each of the feeders extends on the table from near the top of the table toward the border of each adjacent linear feeder, and further, the tip portion extends along the periphery of the table. The present invention is characterized in that a plurality of blades are provided that are curved from the vicinity of the feeder tray toward the center of each linear feeder tray.

Further embodiments include one in which the upper end surface of the blade has a folded structure, and one in which a round bar is provided on the upper end surface of the blade along its length.

<Operation> According to this invention, when an article is fed to the top of the table of the dispersion feeder, a part of it slides between each blade, reaches the peripheral edge of the table, and is fed from there to each linear feeder. Ru. In addition, the remaining articles slide on the upper end surface of the blade and reach the peripheral edge of the table, but since the blade is curved from around this position toward approximately the center of each linear feeder tray, it ends up sliding on the blade. Sliding articles are also fed approximately in the center of each linear feeder.

<Effects> As described above, according to this invention, a blade is provided that extends from the top toward the border of each adjacent linear feeder on the table and whose tip is curved toward each linear feeder. All the articles are fed almost to the center of each linear feeder tray, and even if the side walls of the trays of each linear feeder are overlapped, the articles will not straddle the side walls, reducing combination accuracy and processing speed. can be prevented.

Also, as in the embodiment, if the upper end surface of the blade is folded back or a round bar is provided on the upper end surface,
The articles slide better on the upper end surface of the blade, and the articles on the blade can be quickly fed to each linear feeder.

<Embodiment> As shown in FIG. 1, this embodiment has a dispersion feeder 10 and a plurality of straight feeders 12 like the conventional one.

This dispersion feeder 10 has a substantially conical table 14, and as shown in FIG. 2, a drive source 16 is connected to the lower part of the table 14.
This drive source 16 is constructed by connecting a vibrating member having a generally triangular planar shape to the lower surface of the table, and using a rod-shaped elastic member with each vertex of the triangular vibrating member arranged parallel to and perpendicular to each other. It is connected to a horizontal base, electromagnets are placed between each elastic member at exactly 120 degree intervals, a vibrating member is provided with a member that is attracted by these electromagnets, and three-phase alternating current is applied to the electromagnet. Since the drive source 16 has such a configuration, the table 14 pivots so as to make a substantially circular motion with the top of the table 14 biased outward, as shown in a somewhat exaggerated thin line in FIG. .

Each linear feeder 12 has a tray 18, which consists of a bottom wall 18a and side walls 18b and 18c rising from both edges thereof,
As shown in FIG. 1, the side walls 18b of each tray 18 are adjacent to the side walls 1
They are arranged radially around the periphery of the table 14 so as to overlap with the table 8c. Each straight feeder 12
As shown in FIG. 2, vibration sources 20 are coupled to the lower surfaces of the bottom walls 18a of the trays 18, respectively.
This vibration source 20 is configured to vibrate the tray 18 in the direction indicated by arrow A in FIG.
Although not shown in the drawings, a weighing hopper or an intermediate hopper of the combination weigher is provided below the tip of each tray 18, as in the conventional one.

The same number of metal blades 22 as the linear feeders 12 are provided on the table 14 with their lower end surfaces 22b in contact with the table 14. These blades 22 extend from the cap part 24 provided on the top of the table 14 to the peripheral edge of the table 14, and extend between the boundaries of each linear feeder 12 (adjacent tray 14).
extending along a line segment passing through the overlapping side walls 18b, 18c) of 8 and reaching the cap portion 24;
Further, the tip of each blade 22 is connected to the table 14.
gently curved near the periphery of each tray 1.
It extends to the midsection of 8. Cap portion 24 between upper end surface 22a and lower end surface 22b of each blade 22
The distance S ₃ near the table 14 is shorter than the length of the long, soft article 26 folded in half at the center, and this distance gradually increases toward the periphery of the table 14 . Also, an oblique side 22 extending from the tip of the lower end surface 22b to the tip of the upper end surface 22a.
The distance between c and the upper end surface 22a becomes shorter toward the tip of the upper end surface 22a, forming a sword-like shape.

Furthermore, the distance S between the tip of the upper end surface 22a of the blade 22 and the bottom wall 18a of the tray 18 is selected to be slightly longer than the length of an elongated, soft item 26, such as jelly confectionery or pickled cucumber, when it is folded in half in the middle. The reason for selecting the distance S in this way is to allow the elongated, soft item 26 that reaches the tip of the upper end surface 22a of the blade 22 to quickly fall onto the tray 18.
When it becomes necessary to change S due to the different lengths of the elongated and flexible article 26,
The distance _S2 from the bottom wall 18a of the tray 18 to the periphery _of the table 14 may be adjusted.
This is the distance from the tip of the upper end surface 22a of the blade 22 to the peripheral edge of the table 14, and the value obtained by adding this to the distance _S2 corresponds to the distance S.

The angle θ ₁ that the upper end surface 22 a of each blade 22 makes with the horizontal plane and the angle θ ₂ that the lower end surface makes with the horizontal plane are such that a long and thin soft article 26 can slide on the upper end surface 22 a when vibration is applied to the table 14 . For example, as shown in FIG. 3, θ ₁ is selected to be 20 degrees and θ ₂ is selected to be 30 degrees.

Further, as shown in FIG. 4, the upper end surface 22a of the blade 22 is formed by folding back a metal plate to form a bending radius, and a long and thin soft article is placed on this radiused surface.
6 are in contact with each other. this is,
This is to improve the sliding of the elongated and soft article 26 on the upper end surface 22a of the blade 22. In addition,
As shown in FIG. 5, the upper end surface 22a of the blade 22
A round bar 27 having a diameter d larger than the thickness t may be welded to the bar 27 to improve the slippage of the elongated and soft article 26. Note that in the case of an elongated and soft article 26 that has relatively good sliding properties, it is not necessarily necessary to adopt the configuration shown in FIG. 4 or FIG. 5.

In the distributed supply device configured in this way, the cap portion 2 at the top of the table 14 is rotated.
When a long and soft article 26 is supplied near the table 14, the article is distributed on each table 14, and the article distributed between each blade 22 reaches the periphery while sliding on the upper surface of the table 14, and is distributed on each table 14. It enters the center of the tray 18 of the feeder 12. Furthermore, as shown in FIG. 1, among the items that straddle the blade 22, those that straddle the blade 22 in a state where the item 26 is bent at approximately the center are placed on the blade 22 with both ends of the item 26 in contact with the table 14. The blade 22 slides on the end surface 22a and reaches the periphery of the table 14, and near this periphery, the blade 22 bends toward the center of each tray 18, and the distance S is such that the elongated and soft article 26 is folded in half. Since it is configured to be longer than the length, it is a long and soft article 2
Both ends of the tray 6 rise from the table 14 and the bottom wall 18a of the tray 18, slide along the bent portion, and enter the center of each tray 18. Also, among the objects that straddled the blades 22, those that were not bent evenly in the center may fall onto the table 14 between the blades 22 due to the rotational movement of the table 14 while sliding on the blades 22. , slides on the table 14 and enters the center of the tray 18.

As described above, according to this article supply device, by providing the blade 22, the elongated and soft article 26 straddles the overlapping side walls 18b and 18c of the adjacent trays of each linear feeder 12. Never.

In each of the above embodiments, the side walls of adjacent trays of each linear feeder are overlapped, but it is not necessarily necessary to overlap them, and there may be a gap between the side walls of adjacent trays. In this case, it is possible to prevent elongated and soft articles from falling through the gap.
