In this embodiment, the straight-ahead feeder 2 enables stable transportation of an appropriate amount of articles.

FIG. 3 is a perspective view of the trough 21 of the straight feeder 2, and FIG. 4 is an exploded perspective view thereof.

The trough 21 is for placing the article w and transporting it along a linear transport passage F having a constant width.

The trough 21 of this embodiment is configured by arranging three passage members 23a, 23b, and 23c having a constant narrow width transport passage f in parallel and mounting and connecting them on a support plate 24 made of a thick plate material.

The passage members 23a, 23b, and 23c are formed by refracting the vertical cross-sectional shape of opening the thin plate material upward into a U shape. The left and right side walls of the intermediate passage member 23b and the inner side walls of the left and right outer passage members 23a and 23c are overlapped to divide the wide transport passage F into three narrow transport passages f over the entire length thereof. It is a partition wall 25.

According to the trough 21 of this embodiment, the partition wall 25 formed by overlapping the side walls of the passage members 23a, 23b, and 23c functions as vertical ribs long in the transport direction, and the trough 21 made of a thin plate material has high rigidity. can do. Further, by refracting the plate material to form the passage members 23a, 23b, and 23c, a series of narrow transport passages f without joints of the members are formed in a series along the transport direction at the boundary between the bottom surface and the side walls standing at both ends thereof. It can be formed, and the waste can be smoothly transported without being caught or clogged at the seam. In addition, cleaning and cleaning of the narrow transport passage f becomes easy.

It is a DD end view.

A step d that descends in the transport direction is formed in the intermediate portion of the trough 21 in the linear transport passage F. On the starting end side of the trough 21, which is on the upper side of the transfer, the partition wall 25 is formed lower as the upper side of the transfer, and on the step d and the lower side of the transfer, the partition wall 25 has a constant height. Is formed in.

Here, the inner width of the narrow transport passage f is set to be slightly larger (for example, about 1 mm) than the length of the article w in the sideways stable posture, that is, the maximum length of the article. Further, the height of the partition wall 25 on the lower side of the transport from the step d is slightly higher than the height of the article w in the sideways stable posture, and the height of the step d is also the height of the article w in the sideways stable posture. It is set a little higher than the height.

A tongue piece-shaped locking portion 26 that is inclined upward is bent and formed on the end bottom surface of each narrow transport passage f. The locking portion 26 lightly locks and temporarily holds the article w that has reached the end of transportation, and when the trough 21 is vibration-driven, the angle at which the article w passes over the locking portion 26 (for example, 5). It is tilted up to 10 degrees).

The support plate 24 of the trough 21 is formed by refracting a thick plate material, and is used for attaching and detaching the trough 21 and the vibration exciting mechanism 22. On the lower surface of the support member 24, a locking pin 27 having a large-diameter head, a pair of positioning pins 28, and a hook 29 are provided. The locking pin 27 is locked to the hole edge of the locking hole (not shown) of the vibration plate 22a of the vibration mechanism 22 shown in FIG. 6 so as not to be pulled out upward, and the positioning pin 28 is locked to the vibration plate 22a. Insert into the positioning hole (not shown). In this state, the tip of the locking lever 30a of the buckle-type connecting metal fitting 30 provided on the vibration plate 22a is locked to the hook 29, and the trough 21 is moved to the vibration plate 22a by swinging operation beyond the dead center. It can be connected and fixed, and the trough 21 can be removed from the vibration plate 22a of the vibration mechanism 22 by operating the locking lever 30a in the opposite direction to cross the dead center and disengage from the hook 29.

Further, on the upper surface of the outer peripheral portion of the top cone 6 in the distributed feeder 1, a large number of sending guides 31 for guiding and sending the article w to be conveyed outward to the starting end of the trough 21 of each straight feeder 2 are provided. It is erected at predetermined intervals in the circumferential direction.

The delivery guide 31 is formed in a hollow chevron shape that tapers toward the center of the dispersion feeder 1 and rises toward the outside. The delivery guide 31 is provided so as to cover the starting end of the trough side wall at the starting end of the trough 21 in the straight feeder 2. The intermediate portion of the adjacent delivery guide 31 faces the start end of each trough 21 of the straight feeder 2, and the article w guided between the adjacent delivery guides 31 is smoothly directed to the start end of the transport passage F in the trough 21. It is designed to guide you to.

In the present embodiment, the four types of articles w individually carried into the upper part of the combination scale are dropped and supplied to the vicinity of the centers of the four compartments formed in the dispersion feeder 1, and are dispersed and transported in each compartment. It is supplied to the weighing hopper 4 via the straight feeder 2 and the supply hopper 3. That is, combination weighing is performed using six weighing hoppers 4 per product type.

Here, in the straight-ahead feeder 2, the article is transported as follows.

The article w distributed and transported to the outer peripheral portion of the distributed feeder 1 is guided between the adjacent delivery guides 31 and reaches the start end portion of the linear transport passage F without being caught by the side wall of the start end portion of the trough 21 in the straight-ahead feeder 2. Be sent in.

On the starting end side of the transport passage F, the partition wall 25 is lower toward the better transport side, so that the overlapping articles w can move in the lateral width direction of the path. While being vibrated, the overlap of the articles w is broken, and many articles w are guided to one of the three parallel narrow transport passages f.

The article w guided to the narrow transport passage f takes a stable sideways posture while being vibrated and transported, and is transported while being arranged in a vertical row along each narrow transport passage f.

When the article w is transported to the middle portion of the upper narrow transport passage f, it slides down to the lower narrow transport passage f at the step d. At this time, even if the articles w are overlapped in the narrow transport passage f in the upper stage, the overlap is broken by sliding down at the step d, and the articles w are arranged in a row in the narrow transport passage f in the lower stage.

The height of the step d is preferably higher than the height of the article w in order to break the overlap of the articles w, and in this embodiment, the height of the step d is slightly higher than the height of the article w.

The article w that has reached the end of the trough 21 gets over the locking portion 26 and is sent to the supply hopper 3 while being driven by vibration. However, when the vibration drive is stopped and controlled, the article at the end of the trough w does not get over the locking portion 26 and temporarily stops in a sideways posture. Then, when the excitation drive of the trough 21 is restarted with the discharge operation of the supply hopper 3, the leading article w temporarily stopped at the locking portion 26 is transmitted over the locking portion 26. As a result, spillage of articles from the end of the trough is prevented, and about three articles w are sent to the supply hopper 3 by one delivery.

As described above, according to the present embodiment, the article w supplied to the start end of the trough 21 of the straight feeder 2 is distributed to the three rows of narrow transport passages f in parallel while being vibrated and transported, and does not overlap. It is aligned and transported in three rows, and at the terminal portion, an appropriate amount of about three articles w can be stably supplied to the supply hopper 3 according to the number of narrow transport passages f, and the supply hopper 3 can be stably supplied. An appropriate amount of about 3 articles w can be stably supplied to the measuring hopper 4 via the above.

As a result, in the combination calculation of each weighing cycle, it is possible to prevent the combination from being unsuccessful and achieve a high production amount.
