Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting machine for sorting articles by size.

[0002]

2. Description of the Related Art Conventionally, in a sorter of this type,
At the upper end side of the sieve for sorting articles, it is connected to the eccentric shaft from the drive source and reciprocally swingable, so that it moves up and down while reciprocating in the inclination direction of the sieve by the amount of vertical displacement due to rotation of the eccentric shaft. is there. In addition, since the drive source and the eccentric shaft are connected to each other and the swinging method combines reciprocating swinging and vertical movement in the sieve tilt direction, it is difficult to optimally adjust the upper end and the lower end of the sieve.

[0003]

In such a sorter, the flow of articles in the sieve section can be smoothly and efficiently made uniform without waste according to the type, size, shape quality, etc. of the articles. In order to accurately sort the articles, it is necessary to adjust the amount of reciprocating swing to the properties of the article and simultaneously adjust the amount of up and down swing of the upper and lower ends of the sieve separately to facilitate fine adjustment of up and down reciprocating motion. is there.

[0004]

According to a first aspect of the present invention, there is provided a technical means for arranging a sieve under a hopper for dropping articles, the sieve being slidable. Then, in a sorting machine that sorts articles while swinging the sieve, the upper end of the sieve is connected to a driving source, and is supported by swinging means that can be adjusted to reciprocate by rotation of an eccentric shaft. The roll guide is provided with guide means that can adjust the inclination angle at the lower end side, and it is possible to finely adjust the roll guide angle of the vertical swing amount of the upper end and lower end of the sieve according to the type and size of the article etc. Make a summary. Further, a roll is provided on a roll provided on the sieve by the guide means according to claim 1, and a roll guide provided on a machine frame for guiding the roll along with the swing by the swing means, the tilt angle of which is adjustable. Has a guide rail on the side surface of the roll guide surface for preventing the right and left shifts from the roll guide surface.

[0005]

According to the above technical means, the following effects are obtained. (Claim 1) The upper end side of the sieve is connected to a drive source by an adjusting rod, a connecting rod, etc., which can reciprocate. Further, the upper and lower ends of the sieve are guided by roll guides, which are guide means capable of adjusting the inclination angle. For this reason, the upper end of the sieve can be finely adjusted by adjusting the roll guide to adjust the upper end, and the lower end can be changed by adjusting the vertical movement of the lower end by adjusting the roll guide to vary the sliding drop force. Can be. Adjustment of the adjusting rod and fine adjustment of the inclination angle of the roll guide of the guide means can be performed in accordance with various conditions of the article and the like, so that the optimum sorting suitable for the property of the article can be performed. (Claim 2) A roll provided with a guide means on a sieve, and a guide rail on a side surface of a roll guide surface capable of adjusting an inclination angle provided on a machine frame for guiding the roll along with the swing by the swing means. Since the roll is prevented from moving left and right from the roll guide surface by the guide rail, the work can be performed safely without fear of falling off.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. The sorting machine is set in an inclined manner by swinging means provided between the machine frame 2 and the upper end of the sieve 1 and guide means for supporting (placing) the upper and lower ends of the sieve 1 as shown in the figure. The sieve 1 is swingable. The sieve 1 moves up and down while reciprocating with the rotation of the drive source 12,
The upper end and the lower end of the sieve 1 are placed on a roll guide 33 by guide means. Fine adjustment of the amount of reciprocating movement can be performed by changing the combination of the reciprocating movement adjusting hole 15 of the adjusting rod 20 and the connecting rod shaft 17. The fine adjustment of the vertical movement is performed by the angle adjustment roll guide 33.
After the knob 30 fixing the lever 29 directly connected to the knob is loosened and moved in the direction of arrow 53 for adjustment, the knob 30 is tightened and fixed.

[0007] As shown in the figure, the sieve 1 is inclined downward from the upper end immediately below the inlet of the hopper 3 toward the direction supported by the guide means, and is gradually inclined downward, and is a space surrounded by both side plates and the lower plate. A sorting hole 42 is provided between two sorting plates 41 with an interval therebetween so that articles to be sorted can be sorted into large, medium, and small, and a large sorting room 51, a middle sorting room 61, and a small sorting room. The large, medium and small articles selected from the exit 71 are moved and dropped on the guide plate. The guide means includes a roll 13 rotatably supported on both ends of the lower plate at the upper end and the lower end of the sieve 1,
And a roll guide surface 23 whose tilt angle can be adjusted, which guides the roller as the rocking means swings. The roll guide surface 23 is provided with a guide rail 24 on the side surface of the roll guide surface 23 for preventing the roll 13 from moving right and left, so that there is no fear of the roll 13 coming off, and the work can be performed safely.

For example, when sorting shellfish such as scallops by size, using a sorting plate 41 adapted to each shell, the reciprocating movement amount and the vertical movement amount at the upper end side, which is the place where the stagnation is most likely to occur immediately below the input port of the hopper 3. The angle adjustment of the roll guide 33 for the upper and lower movements of the upper and lower sides of the reciprocating movement and the upper and lower movements of the lower end side and the reciprocating movement amount of the lower end side can be easily adjusted while observing the sorting condition during article sorting. By fine adjustment, the shellfish flows smoothly, and the sorting work of any size is shortened, and the shellfish can be efficiently and accurately selected without damaging the shellfish. In addition, sorting can be performed only by exchanging a sorting plate 41 suitable for an article to be sorted from a small article to a large article by one sorting machine.

[0009]

The present invention has the following advantages because it is configured as described above. (Claim 1) The upper and lower sides of the sieve are guided by roll guides with guide means capable of adjusting the inclination angle, so that the upper and lower sides can be easily adjusted during product selection and fine adjustment can be performed. The amount of vertical movement can be varied according to the size and type of the article, the same sorter can be used regardless of the type, and fine adjustments can be made even in various sizes, depending on the article. The adjustment of the inclination angle of the guide means is set in consideration of the inclination angle at the time of setting the sieve and the amount of vertical movement of the upper end side of the sieve by using a slippery article, an article having a large adhesive force with the sieve, or the like. Therefore, it is possible to correctly sort the articles to be sorted without damaging them, and to perform an efficient and accurate sorting for articles that are easy to roll or have a large frictional resistance. Can be changed to (Claim 2) In addition, since it is composed of a roll provided on the sieve and a roll guide provided on the machine frame and capable of adjusting the inclination angle, it is easy to finely adjust the vertical movement of the upper and lower ends of the sieve. is there. Further, since the guide rails are provided on the side surfaces of the roll guide surface, the sieve roll can be prevented from moving left and right from the roll guide surface, and the work can be performed safely.
