Abstract

PURPOSE:To automate alignment of articles, by a method wherein an aligning device for an article, e.g. spoons, which has a wide part and a narrow part and a deviated center of gravity position, after the articles are aligned in a longitudinal direction, the narrow part is conveyed to a position above a span space, and through utilization of a shape and a center of gravity position, only in an article in one form is caused to pass the span space. CONSTITUTION:Spoons 1 are aligned in a longitudinal direction by means of longitudinal positioning guides 2 and 2, and are conveyed forward by means of endless belts 33a, 33a, and 32a. The tip of the article is protruded in a position above a span space 4. In this case, when a wide part 10 of the spoon 1 is positioned frontward in an advancing direction, at the same time when the wide part 10 is separated from belts 33a' and 33a', the spoon 1 is dropped from a front inclination drop part 40 by means of a center of gravity position. When a narrow part 11 forms a front end and the wide part 10 is up, the narrow part 11 is inclined downward and is thrusted in the front inclination drop part 40 for a drop. Thus, only the spoon in a state that the narrow part 11 is positioned in front and the wide part 10 is down is forced to pass. This constitution enables automation of alignment.

Description

Detailed Description of the Invention (Industrial Application Field) This invention is a spoon, a fork, a spatula, a dental mirror (both mirrors), etc., in which a longer narrow part is raised or lowered from the center of the inner end of the wider part. In a machine for transporting articles that are protruded by a difference and whose center of gravity is located in a narrow part,
The present invention relates to an apparatus for aligning the articles.

(Prior Art) Conventionally, in a transfer machine for the above-mentioned articles, a longitudinal positioning guide is provided protruding along the longitudinal direction of a transfer path such as a belt conveyor, so that the articles, such as spoons, are lined up in the longitudinal direction. .

(Problems to be Solved by the Invention) Even though it is possible to align the objects such as spoons in the longitudinal direction according to the conventional example, it does not mean that the melons have one form. There are 4 types. Firstly, when the spoon, which is the article 1, is facing upward and the scoop part, which is the wide part 10 of the article 1, is facing forward, secondly, when the spoon is facing downward and the scooping part is facing forward, and thirdly, when the spoon is facing upwards. A fourth case is when the handle, which is the narrow part 11, faces forward.Fourth, there is a case where the spoon faces downward and the handle faces forward. Then, it is transported to the terminal in the above four forms by the transport machine,
Provided for the next process. For example, when the next step is to put the articles 1, 1.1, etc. into a transparent packaging material 5 in which a plurality of pockets 50, 50, etc. are arranged in series as shown in FIG. 8, and then seal it. , according to automatic packaging, articles 1, 1, as shown in the figure.
1... are packaged in their original form, which makes them look unattractive when folded, and for this reason, they are sometimes manually changed into the original form and then packaged.

(Means for Solving the Problems) The present invention solves the above-mentioned disadvantages. That is, the narrow portion, which is longer than the wide portion, protrudes from the center of the inner end of the wide portion with a difference in height, and the center of gravity is located at the center of the inner end of the wide portion. A longitudinal positioning guide for the article located in the narrow portion is provided so as to protrude in the longitudinal direction of the transfer path, a spanning space for the narrow portion is formed in the middle of the transfer path, and the article is positioned from behind the spanning space. It is characterized in that the fall prevention part of the wide part extends forward and the space in front of the fall prevention part is formed as a forward tilted fall part of the wide part.

(Configuration of Example) In explaining the configuration of the example, the article 1 to be transferred will be described. The article 1 has a wide portion 10 as shown in the fifth and sixth figures, and a narrow portion 1 extends from the center of the inner end of the wide portion 10.
1 is projected with a difference in height, and the center of gravity G is located in the narrow part 11, and the distance a from the outer end of the wide part 10 to the center of gravity G is equal to the distance from the center of gravity G to the outer end of the narrow part 11. In this description, article 1 is the illustrated plastic spoon. Therefore, the scoop part of the spoon is a wide part 10, and the handle is a narrow part 11. Note that the article 1 is not limited to a spoon. When the article 1 is placed facing upward and the wide portion 10 faces forward as shown in (1) in Fig. 7, the center of gravity G is
Because the article 1 is located at When the article 1 is facing upward and the narrow part 11 is facing forward, as in (
The situation is opposite to (1), and when the article 1 is facing downward and the narrow portion 11 is facing forward as in (4), the situation is opposite to (2).

Next, a first embodiment of the present invention will be described.

Transfer path "3" has three types of belt conveyors 31, 32゜33
The belt conveyor 32 on the upstream side and the belt conveyor 31 on the downstream side are separated to form a spanning space 4 for the narrow portion 11. The belt conveyor 33 is at the same speed as the peltco/bear 32, and has a pair of left and right endless bells) 33
al 33 a, an endless belt 33
a, 33 aH Endless bell of belt conveyor 32) 3
adjacent along the side edge of 2a, an endless bell) 33 a,
The folding position 33b of 33a is extended to the middle of the spanning space 4, and this extended portion is used to prevent the fall prevention part 3 of the wide portion 10.
3a', 33a' are formed, and fall prevention parts 33a', 3
The front space of 3a' is formed as the forward-inclined falling part 40 of the wide portion 10, and the longitudinal positioning guide 2, which consists of a pair of left and right side plates along the longitudinal direction of the transfer path 3 and is separate from the transfer path 3,
20 is equal to the width C', the width of the wide portion 10 is set slightly larger, and the gap between the endless bells 33a and 33a is set slightly larger than the width d of the narrow portion 11. Further, the length B of the spanning space 4 is greater than the sum of the distance a from the outer end of the wide portion 10 to the center of gravity G, plus the straight-line distance E of the article 1 due to inertia, as shown in FIG. 4 (1). At the same time, as shown in FIG. 4 (4), the distance from the center of gravity G to the outer end of the narrow portion 11 is also set small, so that the forward tilting falling portion 40
The length A is the length e of the wide part 10 as shown in Fig. 4 (1).
The width is also large and the wide part 1 as shown in Figure 4 (4).
It is set smaller than the distance a from the outer edge of 0 to the center of gravity G. It should be noted that the straight-line distance E naturally varies depending on the speed of the part 1, and the length A shown in FIG. 4 (4),
The straight-line distance of the article due to inertia may be added to the upper limit of H.

In the second embodiment, the transfer path 3 is an inclined plate, and the principle is the same as the first embodiment, and the same constituent members and the same setting distances are given the same reference numerals and explanations are omitted. I will explain each point. The downstream side of the transfer path 3 has an inclined thin plate 31/
The upstream side is formed by connecting elongated thick plates 33', 33' to both side edges of the inclined thin plate 32', and the elongated thick plate 33'
, ' 33 ' are extended into the spanning space 4 and fall prevention part 3
3a' and 33a' are arranged in series.

(Operation of the embodiment) The operation of the embodiment will be explained with reference to FIGS. 3 and 4. A supply device such as a hopper (not shown) sends the articles to the transfer path 3.
When the articles 1 are dropped one after another, the longitudinal positioning guides 2 and 2 shown in the third figure align the article 1 in one of the directions shown in FIG. Endless Bell) 33 a.

33a, the narrow part 11 is placed on the endless belt 32a and aligned at the center of the transfer path 3, and the article 1
moves forward at a predetermined speed and comes to the spanning space 4. If the article 1 is in the state shown in FIGS. 7(1) and 7(2), even if the wide portion 10 is above the spanning space 4, it will not tilt forward when the center of gravity G is located above the endless bell 32a. Further, even if the center of gravity G exceeds the front end of the endless bell 32a, the article 1 continues to move straight due to inertia as shown in FIGS. 4(1) and 4(2). When the center of gravity G exceeds the straight-line distance E and the wide portion 10 leaves the fall prevention portions 33a', 33a', the wide portion 10 tilts forward and falls from the forward-inclined falling portion 4.0.

Further, when the article 1 is in the state shown in FIG. 7 (3), the narrow portion 11 protrudes from the wide portion 10 with a height difference h (as shown in FIG. 6), and the center of gravity G is in the narrow portion 11. Therefore, on the transfer path 3 in FIG. 4(3), the narrow portion 11 is already
leans forward, and as shown in the figure, the narrow portion 11 plunges into the spanning space 4 and falls. Furthermore, when the article 1 is in the state shown in FIG. 7 (4), the outer end of the narrow portion II is moved before the center of gravity G enters the spanning space 4, as shown by the one-dot chain line in FIG. 4 (4). Since it is hung over the endless bell) 31a, the narrow part 11 does not fall into the forward-inclined falling part 40, and even if the wide part 1o comes to the hanging space 4, the endless bell) 33a, 33a Even if the extended tabs of the endless bell (31a) rest on the falling prevention parts 33a' and 33B' and reach the top of the falling part 40, the center of gravity G is already on the downstream side.
Therefore, the wide portion 10 does not tilt backward at the forward-tilting falling part 40 and fall, and the entire article 1 is placed on the endless belt 3.
1a. Therefore, at the end of the transfer path 3, there is a fourth
Only the articles 1 in the orientation shown in Figure (4) arrive, and in the next process, for example, they are packaged in one direction without being packaged in an unsightly manner as shown in Figure 8. It is something. Note that the same applies to the second embodiment.

(Effects of the Invention) According to the present invention, after the article is made into four longitudinally oriented forms by the longitudinal positioning guide, the three forms of the article are dropped from the hanging space, and only one form is transported to the downstream transfer path. This makes it possible to perform various subsequent processes such as automatic packaging efficiently, and since the structure is simple, the device itself can be provided at a low cost.
