[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an article supply device which is applied to an automatic weighing machine or the like and supplies articles in predetermined amounts.

[0002]

[Prior Art]

 An article supply device is provided in the supply part of the weighing device for weighing the articles. FIG. 6 is a side view showing this article supply device. The supply device 30 supplies the articles conveyed by the conveyor or the like from the previous process to the process device portion next to the weighing device by a predetermined amount. For this reason, the supply device 30 is provided with a hopper 31 for accumulating articles and a feeder 32 for continuously supplying a predetermined amount of articles from the lower part of the hopper 31 to the next process apparatus.

[0003]

[Problems to be solved by the device]

 However, since the article supply device 30 is arranged such that the accumulation direction Y of the articles in the hopper 31 and the article feeding direction X of the feeder 32 are orthogonal to each other, the articles are indicated by Z in the drawing. It was easy to stay in the part. As a result, the articles are unevenly accumulated in the hopper 31, and the supply to the feeder 32 is not performed uniformly, so that the feeder 32 cannot convey a uniform amount. In particular, the above-mentioned problems were likely to occur in an adhesive article.

The present invention has been made in view of the above problems, and is capable of storing articles in a uniform state and further capable of continuously feeding articles in a uniform amount to the next step. Is intended to provide.

[0005]

Means for Solving the Problems In order to achieve the above object, an article supply apparatus of the present invention is an article supply apparatus that stores a predetermined amount of an article W and continuously supplies a predetermined amount to a next process part, The inside of the supply hopper 1 for storing the product W is provided with stirring members 11, 17, 20, 25 for stirring the product W.

[0006]

[Action]

 The stirring members 11, 17, 20, 25 inside the supply hopper 1 for storing the articles W stir the articles W to make the loading state uniform. As a result, the articles W can be stably and continuously discharged from the supply hopper 1, and can be uniformly supplied to the next process.

[0007]

【Example】

 FIG. 1 is a side sectional view showing a first embodiment of the article supply apparatus according to the present invention. The supply hopper 1 is formed in a substantially cylindrical shape in the vertical direction, and the articles W 1 conveyed by the bucket conveyor 3 are sequentially introduced into the supply hopper 1 from the upper upper opening 1a and accumulated in a predetermined amount. It Directly below the lower opening 1b of the supply hopper 1, a linear feeder 5 is provided. The straight feeder 5 includes a lead-out groove 6 horizontally provided from the lower opening 1b to the pool hopper 10 portion of the next process device portion, a feed screw 7 provided in the lead-out groove 6, a base end portion 7b of the feed screw 7. And a drive unit 8 such as a pulse motor for controlling the rotation of the supply screw 7.

The front lower part 1c of the supply hopper 1 on the supply direction of the articles W is a stirring plate 11 as a swingable stirring member. The stirring plate 11 is rotatably supported by a shaft 11a provided at the upper end portion. A bending piece 11b is provided at the upper end portion, and an air cylinder 12 is arranged above the bending piece 11b. Therefore, the stirring plate 11 can be swung about the shaft 11a by the operation of the air cylinder 12.

Next, the operation of the article supply apparatus having the above configuration will be described. A predetermined amount of conveyed articles W are accumulated in the supply hopper 1. The article W is continuously supplied from the lower opening 1b to the leading groove 6 portion of the straight feeder 5. In the linear feeder 5, the drive unit 8 rotates the supply screw 7, conveys the article W in the forward direction F, and sequentially throws it into the pool hopper 10 from the end 7a of the supply screw 7.

At this time, in the supply hopper 1, the agitating plate 11 is swung in the direction A around the shaft 11a by the operation of the air cylinder 12 as shown by the chain line in the figure, and the article W contacting the agitating plate 11 is contacted. Separate them and smooth the loading condition. As a result, the articles W in the supply hopper 1 can be placed in a uniform loaded state without remaining in a part. In particular, when the article W has an adhesive property, the article W adhered in the supply hopper 1 can be discharged.

Next, FIG. 2 is a side sectional view showing a second embodiment of the article supply apparatus of the present invention. In this embodiment, the supply trough 1 in the above-mentioned embodiment is fixed, and a stirring rod 17 protruding to the inside of the supply trough 1 as a stirring member is configured to be movable. The agitating rod 17 is driven by the air cylinder 12 to horizontally reciprocate in the direction B in the figure to scrape away the articles W in contact with the inner wall portion of the supply trough 1 so that the stacked state can be smoothed.

Next, FIG. 3 is a side sectional view showing a modified example of the above-mentioned embodiment. Inside the fixed supply trough 1, a swing bar 20 is swingably provided as a stirring member. There is. The rocking rod 20 is rotatable about an end shaft 21 and is constantly urged downward by a spring member 22. The operating piece of the air cylinder 12 is in contact with the pressing piece 20a on the opposite side of the shaft 21. The swing rod 20 swings in the direction C in the drawing around the shaft 21 by the drive of the air cylinder 12, and the articles W inside the supply trough 1 can be separated and the loaded state can be smoothed.

Next, FIG. 4 is a side sectional view showing a further modified example of the above embodiment. A flat rotary stirring plate 25 is swingably provided as a stirring member inside the fixed supply trough 1. A rotary drive unit 26 such as a rotary cylinder and a motor is provided at an end of the rotary stirring plate 25, and the rotary stirring plate 25 is rotated in the D direction in the drawing. The rotary drive unit 26 is rotatable about a shaft 27 and is always urged downward by a spring member 28. The operating piece of the air cylinder 12 is in contact with the pressing piece 29 on the opposite side of the shaft 21. Therefore, the rotary stirring plate 25 swings around the shaft 27 in the direction of d in the figure by the driving of the air cylinder 12, and the rotary driving unit 26 drives the rotary stirring plate 25 to rotate in the D direction. The articles W can be sorted out to smooth the loaded state.

FIG. 5 is a side cross-sectional view showing a modified example of the feeder portion provided directly below the supply trough 1 described in each of the above-described embodiments, and just below the supply hopper 1 is described in the above embodiment. Instead of the linear feeder 5, a transport trough 15 may be provided as shown in the figure. The transport trough 15 is one in which a trough 15c is provided on a base portion 15a via a leaf spring 15b, and the vibration of the air vibrator 15d causes the trough 15c to vibrate via the leaf spring 15b. The article W is supplied to the pool hopper 10. In this way, the supply hopper 1 provided on the transport trough 15 can also obtain the same supply operation as in the above-described embodiment.

[Effect of the device]

 According to the article supply apparatus of the present invention, since the stirring member is provided inside the supply hopper, the articles can be evenly stored in the supply hopper and can be uniformly supplied. Further, even if the article has adhesiveness, it can be discharged and supplied without continuing to adhere to the inside of the supply hopper.
