Description

[Detailed Description of the Invention] This invention relates to an article supply device that supplies articles to be weighed to each weighing hopper of a combination weigher.

Conventionally, the above-mentioned article supplying device has a structure shown in FIGS.
As shown in the figure, a dispersion feeder 2 having a plurality of outlets 1a to 1i around the circumference is used, and shutters 3a to 3i are provided for these outlets 1a to 1i, respectively.
There was one in which the articles to be weighed 4, 4, . . . were thrown into the hopper 5 by opening and closing these shutters 3a to 3i up and down. However, in such a feeding device, when opening and closing the shutters 3a to 3i, the objects to be weighed 4, 4... may be damaged or
There were cases of damage.

The object of this invention is to provide an article feeding device that can feed articles to be weighed to a hopper or the like without damaging or damaging the articles.

This invention will be explained below based on one embodiment shown in FIGS. 3 and 4. As shown in FIG. 3, this article supply apparatus is comprised of a vibrating dispersion feeder 10 and nine linear vibrating feeders 12a to 12i.

As shown in FIG. 4, the dispersion feeder 10 has a raised central portion and is elevated, and includes a table-shaped vibrating body 14 that is inclined downward toward the outer periphery, and the vibrating body 14.
a surrounding wall 16 provided so as to surround the outer periphery of the surrounding wall 16, and nine normally open outlet ports 18a to 18i provided at equal intervals in the surrounding wall 16 as shown in FIG.
and a vibration source 20 coupled to the lower surface of the vibrating body 14 as shown in FIG.

The linear vibration feeders 12a to 12i have gutters 13a to 13i arranged at each outlet 18a to 18i, and these gutters 13a to 13i are connected to the third
As shown in the figure, the center line thereof forms an acute angle θ with respect to a line connecting approximately the center of each outlet port 18a to 18i and the center of the vibrating body 14, and is arranged in a direction extending diagonally outward. . These gutters 13a to 1
3i are vibration sources 21 as shown in FIG.
a to 21i, and these vibration sources 21a
21i to 21i can vibrate independently of each other.
Furthermore, the gutters 13a to 13i are connected to the dispersion feeder 1.
It is also constructed so that zero vibrations are not transmitted.
In addition, 22 is an article guide wall provided in each gutter 13a to 13i.

Gutter 1 of each straight type vibration feeder 12a to 12i
There is an intermediate hopper 2 below the final end of 3a to 13i.
4a to 24i are provided, and gates 26a to 26i are provided at the bottoms thereof, respectively. Furthermore, weighing hoppers 28a to 28i are provided below the intermediate hoppers 24a to 24i. These weighing hoppers 28a to 28i also have gates 30a to 30i, and weighing devices 32a to 32i for detecting the weight of articles 36 stored therein. These weighing hoppers 28a
A collection chute 34 is arranged below 28i to straddle these. Dispersion feeder 10, linear vibration feeders 12a to 12i,
Intermediate hopper 24a to 24i, weighing hopper 28a
28i to 28i and the collection chute 34 constitute a combination weigher.

The combination weigher configured in this manner includes linear feeders 12a to 12i, gates 26a to 26i,
30a to 30i are configured to be controlled by a combination control section (not shown), and operate as follows. Assuming that the vibration source 20 is always operating, the article 36 supplied to the dispersion feeder 10 from above the center of the dispersion feeder 10 gradually moves toward the outlet ports 18a to 18i. from the intermediate hopper 28a via the corresponding linear vibration feeders 12a to 12i.
The articles 36 are supplied to the feeders 36 through 28i, and an amount approximately equal to the amount supplied is always replenished from the dispersion feeder 10 to the linear vibrating feeders 12a through 12i. The dispersion feeder 10 includes each linear vibration feeder 1
The storage capacity is sufficient to supply the articles 36 to the feeders 2a to 12i, and the articles 36 rotate within the dispersion feeder 10. In this state, if the articles 36 have already been placed in the weighing hoppers 28a to 28i, then the weighing hoppers 28a to 28i
The weighing devices 32a to 32i detect the weight of the stored articles 36 and send it to the combination control section.
The combination control unit selects the optimum combination by combining the respective detected weights, sends a discharge command to the selected weighing hoppers 28a to 28i, for example, 28a, 28c, 28i, and sends a discharge command to the gates 30a, 30c, 28i.
30i, and these weighing hoppers 28a, 28
The articles 36 in c and 28i are put into the collection hopper 34. When the gates 30a, 30c, 30i close, the combination control section closes the gates 26a, 26c, 26
i is opened and the articles 36 in the intermediate hoppers 24a, 24c, 24i are weighed in the hoppers 28a, 28c, 28i.
put it into. When this input is completed, combination weighing is started again. During this combination weighing, the combination control section drives the linear vibration feeders 12a, 12c, 12i for a predetermined period of time, and the intermediate hoppers 24a, 24c, 2
The article 36 is put into 4i and stopped. Articles 36 are constantly replenished from the dispersion feeder 10 in accordance with the amount input from the linear vibrating feeders 12a, 12c, and 12i. Thereafter, operations will be performed in the same manner.

According to this device, the articles 36 are intermittently fed by the linear vibrating feeders 12a to 12i, so the articles 36 are not pressed against movable parts such as shutters of the conventional device, and each weighing hop is No damage occurs to the articles 36 supplied to 28a-28i. Moreover, even if the amount of articles fed onto the linear vibrating feeders 12a to 12i near the delivery ports 18a to 18i varies to some extent,
Since the particles are made uniform while being vibrated while moving toward the intermediate hoppers 24a to 24i, the amount of input to the intermediate hoppers 24a to 24i can be made almost uniform. Further, the dispersion feeder 10 is provided with a surrounding wall 16 at the peripheral edge of the table-shaped vibrating body 14, and the surrounding wall 16 is provided with outlet ports 18a to 18i at equal intervals, and the straight-moving vibrating feeders 12a to 12i have their channels 13a to 18i. 13
i is provided in a direction in which its center line extends obliquely outward at an acute angle with a line connecting approximately the center of the outlet ports 18a to 18i and approximately the center of the table-shaped vibrating body 14, and these gutters 13a to 13i are arranged independently of each other. It is set up to vibrate. Therefore, the outlet ports 18a to 1
No articles 36 are sent out from sources other than 8i, and the remaining articles 36 are transferred to the table-shaped vibrating body 1 of the dispersion feeder 10.
The dispersion feeder 10 is driven by the channels 13a to 13i, which are provided at the outlet ports 18a to 18i so as to form an acute angle to a line connecting the approximate center thereof and the center of the table-like vibrating body 14. Even if the linear feeders 12a to 12i are not driven, the dispersion feeder 1
The pushing force of 0 will not be overcome and the articles 36 will not be supplied indefinitely.

In the above embodiment, the intermediate hoppers 24a to 24i are provided to increase the metering speed, but they may be omitted if high-speed metering is not required. Also,
It may be vibrated intermittently in synchronization with the dispersion feeders 12a to 12i. Furthermore, the number of linear vibrating feeders can be increased or decreased depending on usage conditions.
