The present invention relates to a device for uniformly adjusting the direction of the egg, and more particularly to a device for straightening the pointed portion of the egg in a certain direction.

High-volume, high-performance automated processing machines are used for bulk processing and packaging of eggs. In these automatic processing machines, a mole that adjusts the pointed and blunt parts of the eggs in a predetermined direction, that is, the direction of the eggs, is very important in order to increase the work efficiency and accuracy in each process. For example, if a large number of eggs are rapidly weighed or printed or labeled with date stamps for each egg in rapid flow, the orientation needs to be constant.

Or, in the quality maintenance after the egg packaging, it is common sense to fill the container with the pointed part of the egg under the egg from the point of view of the life science of the egg. Conventionally, many proposals have been made and practiced on the apparatus which makes the direction of a geran constant. However, for each large and small egg that is sent at a processing speed of 20,000 to 70,000 pieces per hour, it is possible to quickly and surely distinguish the sharp and blunt parts of the eggs and to keep the direction constant. In reality it is not easy.

For this reason, the conventional apparatuses have the disadvantage of being functionally low in reliability and brittle or breakdown of eggs, and furthermore, the apparatus itself becomes too large and expensive.

Accordingly, the problem to be solved by the present invention is to provide a device for quickly and surely matching the pointed and blunt parts of the egg.

Features of the present invention are as follows.

That is, the support plate which forms the driven-rotation area | region which rotates by sliding a roller in the back and front of the roller conveyor which carries and conveys eggs between rollers is provided. Further, the rollers are brought into sliding contact between the front and rear support plates at the bottom of the roller conveyor so as to be rotated at the same time as the roller rotation in the forced rotation region at the same time as the roller rotation in the driven rotation region and at the same time. A forced rotation mechanism for forming a forced rotation region, for example, an endless belt or a slide chain is provided. In addition, one side of the roller conveyor has an egg passage formed between the guide members installed side by side on the upper side of the roller conveyor so that the egg is reversed by preventing the movement of the egg moving forward toward the pointed part of the egg between the rollers of the forced rotation area. To protrude.

Eggs sent from the supply conveyor and entered into the driven rotational area are rotated and moved forward toward the pointed portion of the eggs, and are conveyed to the passage while gradually deviating from the conveying direction. However, even if the pointed part of the egg sticks to the guide plate, it does not reverse because the egg's rotation speed is slow in the driven rotation area.

The egg conveyed to the forced rotation region is reversed at high speed and reversed by hindering the movement toward the pointed portion of the egg in the guide member protruding toward the cold side of the roller conveyor. Only in the forced rotation region, the eggs rotate at high speed, so that the moving distance of the eggs for reversal can be shortened. A description of how the egg reverses when the egg moves between the rollers toward the pointed part of the egg and when the movement of the egg is prevented by the guide member will be described later.

Also, the roller conveyor should be inverted twice in the forced rotation area of the egg with the posture toward the same direction in the driven fire zone, and the eggs in the forced rotation area should be inverted once in the forced rotation area. The rotational speed of the roll and the spacing of the guide members are set.

Hereinafter, embodiments of the present invention will be described.

"1" is a known roller conveyor, "2" is a pair of left and right chain wheels installed at the front and rear, and "3" is a pair of left and right chains hooked on the chain wheel (2). "4" is a roller group of the same diameter and is rotatably attached to the chain 3 at equal intervals orthogonal to the conveying direction a of the roller conveyor 1. The ruler 4 is attached to the chain 3 by, for example, rotatably attaching the attachment shaft of the roller 4 to the chain 3 or by inserting a pin protruding from the chain 3 into the roller 4. Or by any other means.

Referring to the driving of the roller conveyor 1, the shaft connecting one of the front and rear chain wheels 2 to the front and rear chain wheels is a main shaft which is powered by a motor not shown in the drawing, and the other left and right chain wheels are connected. Is the driven shaft. Therefore, when the motor is driven, the main shaft is driven so that the chain 3 rotates endlessly in the conveying direction a of the roller conveyor 1, and the eggs supported between the adjacent rollers 4 and the rollers 4 E) is conveyed in the conveying direction a (same as the arrow a direction shown in FIG. 4) of the roller conveyor 1 shown in FIG.

"5" is a support plate, which is installed before and after the roller conveyor 1, and the bottom surface of the roller 4 group is in sliding contact with the support plate. Therefore, each roller 4 is rotated by the support plate 5 in the arrow b direction (that is, counterclockwise rotation) as shown in FIG.

If you look at the motion of the egg, first push the egg placed on a flat surface in the horizontal direction, so the pointed side of the egg draws a small circle, and the blunt side of the egg draws a large circle. It is well known. When the egg E is placed between the two rollers 4 and the roller 4 is rotated on the same principle, the egg E rotates in the same manner as the case in which the egg E is pushed horizontally on a flat surface. However, since the rotating egg E is sandwiched between the rollers 4, it cannot move in a fan shape and moves forward along the roller 4 toward the pointed part side of the egg. When the longitudinal axis of the egg E coincides with the axis of the roller 4, the forward force of the egg E is small, but in fact the axis of the egg E is conveyed in the direction of the arrow a shown in FIG. , Once the shaft is displaced, the residual force is accelerated, and the egg (E) moves forward toward the pointed part.

"6" is a forced rotation mechanism provided on the lower side of the roller conveyor 1, and although a belt is used in the embodiment, a slide chain may be used, for example. The forced rotation mechanism 6 is installed on the lower side of the roller conveyor 1 between the front and rear support plates 5, and the arrow direction c is the same as the conveying direction a of the roller conveyor 1 by a motor not shown in the drawing. Rotate to endless seat.

Therefore, the roller 4 in sliding contact with the forced rotation mechanism 6 is forcibly rotated in the arrow direction d. The rotation of the roller 4 group by this forced rotation mechanism 6 is set to the support plate 5 faster than the rotation of the roller 4 group. That is, the roller conveyor 1 has a high speed zone in which the roller 4 groups are driven by the driven rotation mechanisms 1a and 1b and the forced rotation mechanism 6 in which the roller 4 groups follow by the front and rear support plates 5. It has the forced rotation area 1c which rotates.

"7" is a plate-shaped guide member, and in the embodiment, four pieces are provided along the conveying direction a of the roller conveyor 1 above the roller conveyor 1 at equal intervals from each other. A bar body may be used as the guide member 7 instead of the plate.

"8" is formed between the opposing guide members 7 as a passage of the egg E. As shown in FIG. In the embodiment there are three passages 8 but in practice six are convenient. Originally, the number of these passages 8 is arbitrary. The passage 8 parallel to the conveying direction a near the entrance of the driven rotational region 1a on the conveying start end side of the roller conveyor 1 is to the right of the conveying direction a, that is, to the right of the roller conveyor 1. It bends and enters the forced rotation region 1c. Then, it bends slightly to the left and bends further to the left near the commute of the forced rotation region 1c to enter the driven rotational region 1b on the conveying end side, and then becomes parallel to the conveying direction a.

Therefore, the eggs E, which are not constantly aligned in the pointed and blunt portions of the eggs, which are continuously supplied three by three from the supply conveyor 11, respectively enter the inlet of the passage 8. As shown in FIG. 4, the egg E having entered the passage 8 is moved forward toward the pointed portion of the egg while gradually rotating in the direction of the arrow e by the rotation of the roller 4 by the support plate 5. do. However, since the rotation of the roller 4 is low speed in the driven rotation area 1a, even if the egg E contacts the guide member 7, it will be in a so-called in-place state and cannot be reversed.

The egg E, which has entered the forced rotation region 1c, moves rapidly toward the pointed part side of the egg as shown in FIG. 5 while rapidly rotating in the direction of the arrow f by the rapid rotation of the roller 4. Move. As described above, since the roller 4 rotates rapidly, the forward force of the egg E toward the pointed portion side of the egg E increases, so when the guide member 7 stops the movement of the egg, the sharp end of the egg The guide member 7 is inserted below. And the pointed end of the egg is inserted under the guide member (7), the egg is set up by the forward force and then reversed by the inertia obtained by the forward force. In other words, the reversal is completed in a short time in the forced rotation region 1c.

Here, the rotation of the group of rollers 4 in the forced rotation region 1c in the direction opposite to the rotation direction in the driven rotation regions 1a and 1b is from the driven rotation region 1a to the forced rotation region 1c, Moreover, when the egg E moves from the forced rotation area 1c to the driven rotation area 1b, it is for stopping or delaying rotation of the egg. If the roller 4 is rotating in the same direction, the egg E is slid due to the continuous rotational speed so that it does not move safely and smoothly.

In this embodiment, the pointed portion of the egg group E is set to be aligned on the left side of the roller conveyor 1 in a predetermined direction. Of course, it is also possible to set the pointed portion of the egg to match the right side of the roller conveyor (1).

Moreover, the conveyance speed of the roller conveyor 1, the rotation speed of the roller 4 in the forced rotation area | region 1c, and the space | interval of the guide member 7 are set so that the egg E may reverse as follows. . In other words. The egg E whose sharp part of the egg E entered into the forced rotation region 1c faces the left side in the conveying direction a is inverted once by engaging the guide member 7 and then within the forced rotation region 1c. The guide member 7 on the opposite side, that is, on the right side, is inverted again. In addition, the egg E, which has a sharp portion toward the right, enters the high-speed rotation region 1c, is inverted by engaging the guide member 7, and each of the eggs is conveyed to the driven rotation region 1b by aligning the pointed portions of the egg in a predetermined direction on the left side. do.

In the embodiment, the passage 8 is formed by bending, which may be formed by bending. However, the larger the passage 8, the more efficient the inversion of the eggs E can be.

The egg E which has passed through the driven rotation area 1b is conveyed to the conveyor 12 of the next process, for example, it is packaged in the packaging container by weight via a weight sorter. In addition, when the motor of the roller conveyor 1 and the motor of the forced rotation mechanism 6 are capable of forward and reverse rotation, the conveying direction of the roller conveyor 1 can be reversed from the embodiment, thereby increasing the versatility of the apparatus.

According to the apparatus for uniformly adjusting the direction of the egg according to the present invention, since the forced rotation area is provided to rotate the egg faster than the driven rotation area, the moving distance is shortened in the conveying direction necessary for the egg reversal, thus providing the position of the egg. It can shorten the time to make the device small and can make the device small. In addition, since the rotation direction of the roller group in the forced rotation region is reversed from the driven rotation region, the eggs can be conveyed safely and smoothly. In addition, it is possible to ensure the reversal of the egg by projecting the egg passage into one side of the conveying direction of the roller conveyor in the forced rotation region.
