Abstract

PURPOSE:To make it possible to securely pack particles even in any conditions of particles by erecting four posts with springs at respective corners of a vibrating assembly and placing a vibrating plate having space at the posts for receiving articles. CONSTITUTION:A vibrating assembly 2 is equipped with four posts 11, having springs 12 and a vibrating plate 13. At the upper end of respective posts 11 arranged with the vibrating plate, a screw is attached to keep the vibrating plate 13 with tighten nuts 14 not to get out of place due to the vibration. This vibrating plate 13 is bent upwards at the up- and down-stream sides except the receiving part of articles. After an article is fed to the center via guide plates 8, 8, the vibrating assembly 2 is vibrated by a motor 5 to move vertically the vibrating plate 13 in the respective posts 11 and to pack particles in the article for secure formation under compressing respective springs 12 due to the own weight of the vibrating plate 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a bag sorting machine, and more particularly to a bag sorting machine that can smoothly sort bags.

[Conventional technology]

A conventional bag sorting machine of this type will be explained based on FIGS. 2(a) and 2(b). The bag sorting machine is equipped with a vibrating body (2) arranged above and parallel to a base (1), and the vibrating body (2) and the base (1) are connected to a pair of leaf springs (3) at the front and back. , (3), and the leaf spring (3), (3) is connected to the base (
The diaphragm (2) is configured to swing back and forth around pivot points (4) and (4) with respect to the diaphragm (2), and as a result, the diaphragm (2) vibrates in the front-back direction and the up-down direction. The driving source for the diaphragm (2) is a motor (5), which is installed on the base (1) and located between the leaf springs (3). The rotation of the motor (5) is decelerated through the adjacent reducer (6) and is connected to one leaf spring (
3). The connecting rod (7) is eccentrically attached to the rotating shaft (6a) of the reducer (6), and swings the leaf springs (3), (3) as the reducer (6) rotates, thereby causing vibration. The body (2) is configured to vibrate.

On the other hand, on the upper surface of the vibrating body (2), there is a pair of guide plates (8) for receiving products packed with powder such as flour,
(8) is provided. Kite plate (8).

(8) is formed by forming a width that matches the width dimension after sorting the bag or the length of the first child at the middle end, and gradually expanding the width toward the side that receives the product before sorting the bag. We are trying to make it easier for you to enter.

However, in the case of a product placed in the kite plate (8), (8), the receiving side reaches the center from the receiving side, and the vibrating body (2)
) vibrations will shape the uneven distribution of powder,
Due to the nature of the powder, sufficient shaping cannot be achieved by the action of the vibrating body (2) alone. For this purpose, there is a support column (9) on the discharge side.
), the roller (10) connects to the vibrating body (2) via (9).
It is straddled above. In addition, the vibrating body of the roller (10) (
2) The separation dimension from the bag can be adjusted appropriately to the dimension required for the bag arrangement.

Therefore, if the product is sorted to some extent by the action of the vibrator (2) and then fed under the roller (10), the product will be more thoroughly shaped by the action of the roller (lO).

[Problems to be solved by the invention] When shaping is performed using a roller (lO), for example, as shown in Fig. 3 (
As shown in a), when the downstream side of the product (P) is in a bulging state, the powder in the bulging part can be leveled upstream by the roller (10), but if the bulging part is in the opposite state. In other words, in the case shown in FIG. 6(b), the rollers (10) push the product more and more in one direction, and in extreme cases, it may become difficult to even move the product.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a bag-shaping machine that can reliably level the powder no matter what state it is in, and can perform sufficient shaping.

(Means for Solving the Problems) A bag sorting machine according to the present invention has a support having a spring erected at a corner of a vibrating body, and a vibration plate is arranged on the support with a space left for receiving the product. It was established.

[Effect]

According to the present invention, when a product is received, the vibrating body vibrates to even out the uneven distribution of powder in the product, and this vibration causes the diaphragm to vibrate up and down with the help of the spring of the support. At this time, the top surface of the product is gradually leveled and shaped into a flat surface.

[Example] Below, Fig. 1 (a), (b) and Fig. 2 (a),
Same as the conventional method based on the embodiments shown in (b) and (c).
Also, the present invention will be described with the same reference numerals used for corresponding parts and the description thereof will be omitted.

As shown in FIGS. 1(a) and 1(b), the device of this embodiment has four wooden supports (11) erected on the vibrating body (2), and each support (11) is equipped with a spring (12). is inserted. A diaphragm (1) is attached to each pillar (11) into which a spring (12) is inserted.
3) is provided. Of course, holes (not shown) are formed in the diaphragm (13) through which each support column (11) can be inserted. A male screw is formed at the upper end of each support column (11) on which a vibrating body (13) is disposed, and a nut (14) is screwed into each column to prevent the vibrating plate (13) from coming off due to vibration. As is clear from the figure, the diaphragm (13) is bent upward toward the upstream and downstream sides, leaving a portion where the product is accommodated. As with the guide plate (8), this is for the convenience of receiving and dispensing products.

Further, the spring (12) inserted into the support column (11) has a length that matches the thickness of the product. Therefore, when shaping products with different thicknesses, it is necessary to prepare springs (12) corresponding to the shapes.

However, when the product is received in the center via the guide plates (8) and (8), the vibrating body (2) moves to the motor (5).
At the same time, the diaphragm (13) vibrates from each pillar (
11) is moved up and down, and at this time, each spring (12) is compressed by the weight of the diaphragm (13), and the powder in the product is leveled. In this embodiment, in order to shape the product (P) by vertical vibration of the diaphragm (13), for example, as shown in FIG.
, (b) and (c), even if the powder bulges in any part, it can be gradually leveled and reliably shaped.

[Effects of the Invention] As described above, according to the present invention, when shaping a product packed with powder in bags, it is possible to reliably shape the product even if the powder is unevenly distributed in any part, thereby achieving smooth shaping work. can do.
