Description

  The present invention relates to an improved invention of an agricultural and livestock product egg distributing and aligning apparatus for sorting randomly supplied eggs, fruits, vegetables and the like into predetermined rows.

  Eggs which are a kind of agricultural and livestock products laid in the poultry house are carried out by the raw egg conveyors arranged side by side and transferred to the supply conveyor. Thereafter, the eggs are divided into predetermined rows of, for example, 6 rows or 12 rows in the width direction orthogonal to the carrying direction during the carrying.

  The sorted eggs are sent to a processing apparatus that performs a cleaning process, a drying process, a sorting process, and the like in that state. In order to maximize the processing capability of the processing apparatus, it is necessary to smoothly and efficiently sort the eggs conveyed by the supply conveyor.

  By the way, eggs laid in a poultry house are not constant due to individual differences of chickens and various conditions such as seasons, and the number of eggs to be conveyed varies. In addition, due to the asymmetry of the outer shape of the egg, the egg is conveyed at random on the supply conveyor.

  For this reason, when the eggs are divided into predetermined rows, the eggs cannot be divided uniformly into multiple rows, or the eggs may become jammed and cannot be sorted smoothly. Things often happen.

  The above-mentioned congestion of eggs refers to a state in which eggs are concentrated and locked in a specific row when eggs are divided into predetermined rows, or eggs are raised when they come into contact with each other. When such a phenomenon occurs, there is a problem that the processing efficiency of the processing device is reduced because the eggs are supplied to the processing device without being equally divided. In addition, there is a problem that an egg located on the upstream side in the conveying direction exerts pressure on an egg located on the downstream side, and the egg is damaged or broken.

  In order to solve such a problem, an egg that is arranged between a supply conveyor that randomly supplies eggs and a delivery conveyor that sends eggs to a downstream processing apparatus and divides the randomly supplied eggs into a predetermined row. Distributing and aligning apparatus, wherein a third conveyor, a second conveyor, and a first conveyor are arranged in order from the upstream side of the transport path, and a sensor for detecting the density of eggs is provided on the third conveyor, and a detection signal of the sensor Based on the above, there has been proposed an egg distribution / alignment device that controls the driving speed of the supply conveyor (see, for example, Patent Document 1).

JP 2003-206016 A

  However, the conventional egg dispensing / alignment apparatus has the following problems. That is, at the time when the sensor detects that eggs are crowded on the conveyor, the eggs are already congested on the conveyor, and it has been difficult to alleviate the egg traffic.

  Therefore, the applicant of the present invention is provided with a first conveyor, a second conveyor, and a third conveyor in PCT / JP2006 / 312599 (unpublished) in order to fundamentally solve the problems of the egg distributing and aligning apparatus. Consists of the first conveyor, the second conveyor, and the third conveyor as Q1, Q2, and Q3, respectively, and the processing capacity per unit time of the processing apparatus as Q4. The capacity Q3 is higher than the transport capacity Q2, the transport capacity Q2 is equal to the transport processing capacity Q4, and in the second conveyor, the force that the conveyor body restricts the movement of eggs, the conveyor body in the first conveyor moves the agricultural and livestock products. An application was made for an apparatus for distributing and aligning agricultural and livestock products set higher than the limiting force.

  The distribution and alignment apparatus for agricultural and livestock products filed by the applicant of the present application is such that when the eggs exceeding the conveying capacity Q2 of the second conveyor are sent to the first conveyor due to the above-described configuration, the first conveyor is a buffer. It becomes possible to prevent the eggs exceeding the conveying capacity Q2 of the second conveyor from being fed into the third conveyor. As a result, in the third conveyor having a higher conveying capacity Q3 than the second conveyor, when the eggs are divided into predetermined rows arranged in the width direction, the egg congestion phenomenon that occurs when a large amount of eggs are conveyed, The lock phenomenon or the egg swell phenomenon is reliably suppressed, and the damage and breakage of the egg can be greatly reduced. And in a processing apparatus, the egg exceeding the conveyance processing capacity Q4 is not sent, and there exists an effect that a predetermined process can be performed to an egg efficiently and smoothly.

  However, in the agricultural and livestock product distribution and alignment apparatus filed by the present applicant, there remains room for improvement in terms of the problem of feeding an amount of eggs corresponding to the conveyance processing capacity per unit time of the processing apparatus. That is, if the amount of eggs transported from the supply conveyor far exceeds the transport capacity Q2 per unit time of the second conveyor and the eggs cannot be temporarily stored near the downstream side of the first conveyor, the first conveyor Eggs that have accumulated and stagnated in the vicinity of the downstream side of the conveyor may exert pressure on the eggs located on the downstream side, pushing the eggs on the second conveyor to the third conveyor. As a result, there has been a problem that eggs having a transfer processing capacity Q4 or more per unit time of the processing apparatus are fed.

  Moreover, when the amount of eggs transported from the supply conveyor was far below the transport capacity Q2 per unit time of the second conveyor, the eggs had to be sent to the processing apparatus with a vacant space.

  Therefore, the present invention has been made with the object of solving the above-mentioned problems. The purpose of the present invention is to convey the amount of agricultural and livestock products from the supply conveyor per unit time of the second conveyor. Agricultural products that can exceed the capacity Q2 and can prevent the agricultural and livestock products on the second conveyor from being pushed out to the third conveyor even if the agricultural and livestock products are excessively accumulated on the downstream side of the first conveyor. An object of the present invention is to provide a livestock product distribution and alignment apparatus. Also, if the transport amount of agricultural and livestock products from the supply conveyor is far below the transport capacity Q2 per unit time of the second conveyor, the agricultural and livestock products can be quickly processed downstream without causing empty space. An object of the present invention is to provide an apparatus for distributing and aligning agricultural and livestock products that can be fed to a farm.

  In order to solve the above problems, in the invention of the distribution and alignment apparatus for agricultural and livestock products according to claim 1, a first conveyor for conveying agricultural and livestock products supplied at random by a supply conveyor, and a downstream of the first conveyor Agricultural and livestock product second conveyor arranged on the side and conveyed by the first conveyor, and a width perpendicular to the conveying direction of the agricultural and livestock product arranged on the downstream side of the second conveyor and conveyed by the second conveyor A third conveyor that conveys the food while being divided into predetermined rows arranged in a direction, and sends the processed food to a processing device that performs a predetermined process on the agricultural and livestock products, the first conveyor, the second conveyor, and the third conveyor If the carrying capacity per unit time is Q1, Q2 and Q3, and the carrying processing capacity per unit time of the processing apparatus is Q4, the carrying capacity Q1 and the carrying Each of the forces Q3 is higher than the transfer capability Q2, the transfer capability Q2 is equal to the transfer processing capability Q4, and in the second conveyor, the force that the second conveyor body restricts the movement of agricultural and livestock products is the first. In the agricultural and livestock product distribution / alignment apparatus in which the first conveyor main body of the conveyor is set to be higher than the force that restricts the movement of the agricultural and livestock products, the first conveyor includes the agricultural and livestock products downstream on the first conveyor. An integrated state detecting means for detecting the integrated state is provided, and further, a control means for controlling the driving of the supply conveyor based on the detection signal detected by the integrated state detecting means.

  In the invention in the agricultural and livestock product distribution and alignment apparatus according to claim 2, in the invention according to claim 1, the accumulation state detecting means detects an excessive accumulation state of the agricultural and livestock products on the downstream side on the first conveyor. And the control means decelerates or drives the driving speed of the supply conveyor based on a detection signal from the accumulation state detection means that detects an excessive accumulation state of agricultural and livestock products on the downstream side of the first conveyor. It is characterized by controlling to stop.

  As is apparent from the above description, in the agricultural and livestock product distribution and alignment apparatus according to the present invention, each of the conveyance capability Q1 of the first conveyor and the conveyance capability Q3 of the third conveyor is higher than the conveyance capability Q2 of the second conveyor. The conveying capacity Q2 of the second conveyor is set equal to the conveying capacity Q4 of the processing apparatus, and the conveying capacity Q2 of the second conveyor is configured to limit the conveying capacity of the agricultural and livestock product distribution and alignment apparatus. Further, in the second conveyor, the force by which the second conveyor body restricts the movement of agricultural and livestock products is set higher than the force by which the first conveyor body in the first conveyor restricts the movement of agricultural and livestock products. It has become. Furthermore, it is the structure which controls the drive of a supply conveyor based on the accumulation state of the agricultural and livestock products in the downstream on the 1st conveyor detected by the accumulation state detection means.

  Therefore, when the transport amount of agricultural and livestock products from the supply conveyor far exceeds the transport capacity Q2 per unit time of the second conveyor, and the agricultural and livestock products cannot be temporarily stored on the downstream side of the first conveyor. By controlling the supply conveyor to decelerate or stop, it is possible to prevent the agricultural and livestock products accumulated on the downstream side of the first conveyor from acting on the agricultural and livestock products on the second conveyor in advance. There is an effect that the problem of extruding agricultural and livestock products on the second conveyor to the third conveyor can be solved.

  Next, as an embodiment of the agricultural and livestock product distribution and alignment apparatus according to the present invention, an egg distribution and alignment apparatus T will be described with reference to the accompanying drawings.

  1 is a plan view of an egg dispensing and aligning apparatus T according to an embodiment of the present invention, FIG. 2 is a schematic side view of the egg dispensing and aligning apparatus T shown in FIG. 1, and FIG. 3 is a second conveyor. It is a partial side view explaining the conveyance state of the egg E by 2. FIG. As shown in FIGS. 1 and 2, the distribution and alignment apparatus T includes a first conveyor 1, a second conveyor 2, and a third conveyor 3.

  Eggs E supplied from a poultry house (not shown) by the supply conveyor 10 are sent from the first conveyor 1 to the third conveyor 3 via the second conveyor 2, and then the eggs E are subjected to predetermined processing such as washing and sorting. Is sent to the processing device 20. A series of operations of the egg distributing and aligning apparatus T including driving of the supply conveyor and the first to third conveyors 3 is controlled by the control means 4.

  As shown in FIG. 1, the first conveyor 1 includes a mesh belt 1 a as a conveyor body that conveys an egg E (not shown) supplied by a supply conveyor 10 toward the second conveyor 2. As the mesh belt 1a, for example, a plastic resin mesh belt in which an opening having a size of about several tens of mm × several mm is formed with an opening ratio of about 40% so that friction with the egg E is reduced. Is preferred. The aperture ratio refers to the ratio of the area of the opening to the total area of the mesh belt 1a.

  Further, as shown in FIG. 1, it is preferable to provide a sorting member 1b for sorting eggs E transported by the mesh belt 1a in a width direction substantially orthogonal to the transport direction X at a predetermined position above the mesh belt 1a.

  In the first conveyor 1, when the egg E is jammed in the transport width direction without any gap, the force of the egg E that tries to spread in the transport width direction is applied to both side walls of the first conveyor 1, and the egg E is damaged. May be damaged or damaged. In order to prevent such a situation, it is preferable to form both side walls of the first conveyor 1 at 90 degrees or more, for example, 125 degrees to 135 degrees. More preferably, it is 135 degrees.

  If it does in this way, the force of the egg E which is going to spread in the conveyance width direction in the 1st conveyor 1 can be escaped diagonally upward. As a result, damage and breakage of the egg E can be prevented, and the phenomenon that an egg E on the second conveyor 2 described later is pushed out to the third conveyor 3 can be alleviated.

  The 2nd conveyor 2 is provided with the bar conveyor 2a as a conveyor main body which conveys the egg E conveyed by the 1st conveyor 1 toward the 3rd conveyor 3, as shown in FIG. The bar conveyor 2a includes a plurality of bars 2b extending in the width direction, and each bar 2b is attached at a predetermined interval in the transport direction. As shown in FIG. 3, in this bar conveyor 2a, the egg E is conveyed in the state mounted between the two bars 2b located in front and back.

  In the mesh belt 1a having a small friction with the egg E, the egg E placed on the mesh belt 1a is relatively easy to move with respect to the mesh belt 1a. On the other hand, in the bar conveyor 2a, the movement of the egg E is restricted by placing the egg E between the two bars 2b as compared with the case on the mesh belt 1a.

  That is, the force that the bar conveyor 2a in the second conveyor 2 restricts the movement of the egg E is stronger than the force that the mesh belt 1a in the first conveyor 1 restricts the movement of the egg E. As shown in FIG. 3, since the egg E is supported in the front-rear direction of conveyance by a plurality of bars 2b extending in the conveyance width direction, the movement of the egg E in the conveyance direction is particularly limited with respect to the bar conveyor 2a. The

  The 3rd conveyor 3 is provided with the mesh belt 3a which conveys the egg E conveyed by the 2nd conveyor 2 toward the processing apparatus 20, as shown in FIG. The opening ratio and material of the mesh belt 3a are preferably substantially the same as those of the mesh belt 1a of the first conveyor 1.

  Further, the third conveyor 3 is provided with a plurality of guide members 3b for guiding the conveyed egg E in the width direction, for example, by dividing the egg into 12 parts. Each of the plurality of guide members 3b extends in the transport direction, and is provided at an interval such that one egg E enters in the width direction. When one passage through which the eggs E are conveyed after being divided by the guide member 3b is referred to as a row, in the third conveyor 3, the eggs E are divided into 12 rows by the guide member 3b. Thus, the eggs E that have been sorted and sent to the processing device 20 are subjected to predetermined processing such as washing, drying, and sorting by the processing device 20.

  In the egg distribution / alignment apparatus T, the conveying capacity of the eggs E per unit time of the first conveyor 1, the second conveyor 2, and the third conveyor 3 is Q1, Q2, and Q3, respectively. Assuming that the carrying capacity of Q4 is Q4, the carrying ability Q1 and the carrying ability Q3 are set higher than the carrying ability Q2. The carrying capacity Q2 is set to be equal to the carrying processing capacity Q4, thereby limiting the carrying capacity of the egg distribution / alignment apparatus T.

  With the above-described configuration, the egg distributing and aligning apparatus T has the egg E that cannot be transported by the second conveyor 2 even if the egg E exceeding the transport capability Q2 per unit time of the second conveyor 2 is transported from the upstream side. Is a function of accumulating on the downstream side of the first conveyor 1, that is, a buffer function for temporarily storing the eggs E transported by the first conveyor 1 exceeding the transport capacity Q 2 per unit time of the second conveyor 2. I have.

  The carrying capacity is an estimate of the amount that can be carried per unit time in a state where eggs of a predetermined size are ideally arranged. In the egg transport, for example, eggs of different sizes are naturally included, so the actual transport capacity varies to some extent with respect to the estimated transport capacity value. Therefore, the condition that the conveyance capability Q2 described in this specification is equal to the conveyance processing capability Q4 is not intended to be mathematically equal, and it should be understood that such a variation in numerical values is also included. plan.

  As shown in FIGS. 1 and 2, the egg distribution / alignment apparatus T includes an accumulation state detection unit 5 that detects an accumulation state of the eggs E accumulated on the downstream side of the first conveyor 1. The integrated state detection means 5 includes a projector 5a, a light receiver 5b, and a timer 5c that is electrically connected to the light receiver 5b and detects a time during which the light emitted from the projector 5a is blocked. .

  More specifically, as shown in FIG. 1, the light projector 5a and the light receiver 5b of the integrated state detecting means 5 are arranged opposite to each other with a mesh belt 1a interposed at a predetermined position near the discharge end of the first conveyor 1. Yes.

  As a result, when the eggs E accumulated on the downstream side on the first conveyor 1 are extremely increased and accumulated up to the positions of the light projecting and receiving devices 5a and 5b, the light emitted from the light projecting devices 5a is blocked by the eggs E and received. The vessel 5b is not reached. Then, the time during which the light is continuously shielded is detected by the timer 5c, and an electric signal based on the detected light shielding time is output to the controller 6 described later.

  Further, as shown in FIGS. 1 and 2, the egg distributing and aligning device T is a controller that controls the driving speed of the supply conveyor 10 based on the electrical signal based on the light shielding time detected by the accumulation state detecting means 5. 6 is provided.

  More specifically, the controller 6 performs control when the light shielding time detected by the integrated state detecting means 5 is a set time t1 (for example, 2 seconds or more and less than 3 seconds) preset in the controller 6. An electric signal is output to the means 4. And the control means 4 which received this electric signal outputs a control signal to the drive means M0 of the supply conveyor 10, and it controls to make the drive speed of this drive means M0 low.

  As a result, the driving speed of the supply conveyor 10 is reduced, and the conveyance amount of the eggs E conveyed from the supply conveyor 10 to the first conveyor 1 is suppressed. Therefore, since the eggs E accumulated on the downstream side on the first conveyor 1 are gradually conveyed to the next process, the pressure on the second conveyor 2 is caused by the pressure of the eggs E accumulated on the downstream side on the first conveyor 1. The phenomenon that the egg E is pushed out to the third conveyor 3 can be prevented beforehand.

  The controller 6 sends an electrical signal to the control means 4 when the light shielding time detected by the integrated state detection means 5 is a preset time t2 (for example, 3 seconds or more) preset in the controller 6. Output. And the control means 4 which received this electric signal outputs a control signal to the drive means M0 of the supply conveyor 10, and it controls to stop the drive of this drive means M0.

  As a result, the driving of the supply conveyor 10 is stopped, and the egg E is not sent from the supply conveyor 10 to the first conveyor 1. In this case, since the eggs E accumulated on the downstream side on the first conveyor 1 are quickly conveyed to the next process, the pressure on the eggs E accumulated on the downstream side on the first conveyor 1 causes The phenomenon that the egg E is pushed out to the third conveyor 3 can be prevented in advance.

  The set times t1 and t2 set in the controller 6 can be changed as appropriate. The egg distribution and alignment apparatus T according to the present embodiment is configured as described above.

  Next, the operation of the above-described egg distribution / alignment apparatus T will be described. First, eggs laid in a poultry house are not constant due to individual differences among chickens, and the number of eggs transferred varies. Therefore, in the description of the operation, it is assumed that the egg E exceeding the transport capacity Q2 per unit time of the second conveyor 2 that controls the transport capacity is transported to the egg distribution and alignment apparatus T. .

  First, the eggs E laid in the poultry house are carried out by a raw egg conveyor arranged side by side and transferred onto the supply conveyor 10.

  As shown in FIG. 1, the egg E conveyed to the first conveyor 1 by the supply conveyor 10 is moved in the width direction orthogonal to the conveying direction X by the sorting member 1 b provided above the mesh belt 1 a. Sorted. The eggs E distributed in the width direction in the first conveyor 1 are packed without gaps in the width direction, and are fed into the second conveyor 2 while maintaining the state.

  The eggs E distributed in the width direction in the first conveyor 1 are fed into the second conveyor 2 in that state. As shown in FIG. 3, in the second conveyor 2, the egg E is supported in a state where the egg E is supported between the two bars 2 b located at the front and back, and the movement of the egg E with respect to the bar conveyor 2 a is restricted. Will be transported. By restricting the movement of the egg E in the conveying direction with respect to the bar conveyor 2a, in the second conveyor 2, a phenomenon in which one egg E moves another egg E positioned before and after the egg E is suppressed, and the egg E is wide. It is possible to maintain a state that is sorted in the direction.

  In particular, in this case, since the eggs E exceeding the conveying capacity Q2 per unit time of the second conveyor 2 are conveyed, the second conveyor 2 is packed without gaps in the width direction, and moreover is a bar conveyor. The eggs E are sequentially conveyed in a state in which the movement of the egg E in the conveying direction with respect to 2a is limited. Further, the eggs E that cannot be transported by the second conveyor 2 are accumulated on the downstream side of the first conveyor 1.

  At this time, since the mesh belt 1a of the first conveyor 1 is formed of a plastic resin having a relatively small frictional force with the egg E, the mesh belt 1a tries to stagnate beyond the conveying capacity Q2 per unit time of the second conveyor 2. The mesh belt 1a is driven to slide under the egg E to be moved, and the eggs E that cannot be conveyed by the second conveyor 2 can be gradually accumulated from the downstream side toward the upstream side. That is, the first conveyor 1 functions as a buffer that temporarily stores the eggs E that are transported exceeding the transport capability Q2 per unit time of the second conveyor 2.

  Thus, even if the egg E is transported exceeding the transport capability Q2 per unit time of the second conveyor 2, the second conveyor 2 corresponds to the transport processing capability Q4 of the processing device 20 per unit time. A quantity of eggs E can be fed into the third conveyor 3. In the third conveyor 3, the eggs E distributed in the width direction with almost no gap are fed almost uniformly into the 12 rows partitioned by the guide members 3b by the mesh belt 3a, and are conveyed while being guided by the respective guide members 3b. Is done.

  The eggs E divided by the third conveyor 3 are conveyed to the processing device 20. In the processing apparatus 20 in which the amount of eggs E corresponding to the transport processing capacity Q4 per unit time of the processing apparatus 20 has been sent, the predetermined processes such as the cleaning process, the drying process, and the sorting process are smoothly performed without delay. It will be applied efficiently.

  By the way, even if the frictional force with the mesh belt 1a per egg is relatively small, the conveying amount of the egg E from the supply conveyor 10 far exceeds the conveying capacity Q2 per unit time of the second conveyor 2, When the number of eggs E accumulated on the downstream side of the first conveyor 1 is extremely increased, the frictional force of the mesh belt 1a that is driven while sliding under the eggs E becomes a large force in the accumulated eggs E as a whole. . As a result, it is assumed that the egg E on the second conveyor 2 is pushed out to the third conveyor 3.

  In such a case, as shown in FIG. 4, the group of eggs E accumulated on the downstream side of the first conveyor 1 reaches almost the center of the first conveyor 1. If it does so, while the light radiate | emitted from the light projector 5a of the integrated state detection means 5 will be interrupted | blocked by the egg E, the electric signal based on the interruption | blocking time of the light will be output to the controller 6 via the timer 5c.

  The controller 6 sends an electrical signal to the control means 4 when the light shielding time detected by the integrated state detection means 5 is a set time t1 (for example, not less than 2 seconds and less than 3 seconds) preset in the controller 6. Output. And the control means 4 which received this electric signal outputs a control signal to the drive means M0 of the supply conveyor 10, and it controls to make the drive speed of this drive means M0 low.

  As a result, the driving speed of the supply conveyor 10 is reduced, and the amount of the egg E transported from the supply conveyor 10 to the first conveyor 1 is suppressed. Therefore, since the eggs E accumulated on the downstream side on the first conveyor 1 are gradually conveyed to the next process, the pressure on the second conveyor 2 is caused by the pressure of the eggs E accumulated on the downstream side on the first conveyor 1. The phenomenon that the egg E is pushed out to the third conveyor 3 can be prevented beforehand.

  The controller 6 sends an electrical signal to the control means 4 when the light shielding time detected by the integrated state detection means 5 is a preset time t2 (for example, 3 seconds or more) preset in the controller 6. Output. And the control means 4 which received this electric signal outputs a control signal to the drive means M0 of the supply conveyor 10, and it controls to stop the drive of this drive means M0.

  As a result, the driving of the supply conveyor 10 is stopped, and the egg E from the supply conveyor 10 to the first conveyor 1 is not sent. In this case, since the eggs E accumulated on the downstream side on the first conveyor 1 are quickly conveyed to the next process, the pressure on the eggs E accumulated on the downstream side on the first conveyor 1 causes The phenomenon that the egg E is pushed out to the third conveyor 3 can be prevented in advance. Thereby, the quantity of eggs E corresponding to the conveyance processing capacity Q4 per unit time of the processing apparatus 20 can be fed into the processing apparatus 20 without damaging or breaking the egg E.

  In the present embodiment, the accumulation state of the eggs E accumulated on the downstream side on the first conveyor 1 is detected by the optical sensor, and the supply conveyor 10 is driven based on the time during which the light from the optical sensor is blocked. However, the present invention is not limited to this and may be implemented as follows.

  For example, an image acquisition sensor such as a monitor camera is provided at an upper position of the first conveyor 1 to grasp the accumulation state of the eggs E accumulated on the downstream side of the first conveyor 1 based on the acquired image data. When it is determined that the number of eggs E accumulated on the downstream side of the conveyor 1 is in an excessive state, the driving speed of the supply conveyor 10 is lowered or controlled to stop driving, and the first When it is determined that the accumulation state of the eggs E on the conveyor 1 is extremely reduced, the driving speed of the supply conveyor 10 may be controlled to be increased.

  As another modification, a weighing scale is built in the first conveyor 1, and the accumulation state of the eggs E accumulated on the downstream side on the first conveyor 1 is grasped based on the measured weight information. If it is determined that the number of eggs E accumulated on the downstream side of the first conveyor 1 is in an excessive state, the driving speed of the supply conveyor 10 is lowered or controlled to stop driving, and When it is determined that the accumulation state of the eggs E on the first conveyor 1 is extremely lowered, the driving speed of the supply conveyor 10 may be controlled to be increased.

  As another modification, the load torque of the driving means M1 of the first conveyor 1, that is, the current value is measured, and the accumulation state of the eggs E accumulated on the downstream side on the first conveyor 1 based on the measured current value When it is determined that the number of eggs E accumulated on the downstream side of the first conveyor 1 is excessive, control is performed to reduce the driving speed of the supply conveyor 10 or to stop driving. And when it determines with the accumulation state of the egg E on the 1st conveyor 1 having fallen extremely, you may control to make the drive speed of the supply conveyor 10 high.

Furthermore, the detection of the accumulation state of the eggs E on the first conveyor 1 may be performed by the following method.
(A) Both side walls of the first conveyor 1 are formed at 90 degrees or more, for example, 135 degrees.
(B) A diffuse reflection type photoelectric sensor in which a projector and a light receiver are integrally formed is installed on each wall surface near the discharge end of the first conveyor 1.
(C) About installation of a photoelectric sensor, it installs so that the direction of the light radiate | emitted from a light projector may become the direction opposite to the conveyance direction X of the 1st conveyor 1. FIG.
(D) The sensitivity is adjusted so that, for example, a shield in front of 180 mm to 200 mm can be stably detected from the photoelectric sensor.
(D) In the first conveyor 1, when the egg E is jammed in the transport width direction without any gap, and the egg E that is about to spread in the transport width direction is pushed obliquely upward along the wall surface. This is detected by the photoelectric sensor, and the driving of the supply conveyor 10 is controlled based on this detection signal.

  In the case of (d), with regard to the timing for detecting the accumulation state of the egg E on the first conveyor 1, if the photoelectric sensor is installed in the vicinity of the mesh belt 1a of the first conveyor 1, the accumulation state of the egg E is detected early. can do. Further, if the photoelectric sensor is installed away from the mesh belt 1a of the first conveyor 1, the accumulation state of the eggs E can be detected later. A preferred installation position of the photoelectric sensor is about 75 mm from the side end of the mesh belt 1a.

  In the present embodiment, an egg is described as an example of an object to be distributed and aligned by the distribution and alignment apparatus. However, the distribution and alignment apparatus is not limited to the egg distribution and alignment apparatus. Needless to say, the present invention can also be applied to distribution and alignment of agricultural and livestock products such as spherical fruits.
