BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an egg transport control device for controlling the transport of a conveyor provided for collecting eggs after spawning.

0002

[Prior Art] Eggs are sent from an egg collection device to a post-processing device such as a washing/sorting/packing device connected to the rear of the device, and the amount of eggs supplied at the entrance of the post-processing device exceeds the throughput capacity of the post-processing device. Japanese Patent Laid-Open No. 62-295817 discloses an egg supply amount adjusting device that controls the conveying speed of an egg collection device when the eggs are collected.

0003

[Problems to be Solved by the Invention] In recent years, egg processing equipment has become larger in order to increase the throughput.
It has grown to the point where it can process 10,000 to 50,000 eggs. In order to maintain the operating rate of this large-scale egg processing apparatus at approximately 100%, it is necessary to supply a sufficient amount of eggs. However, compared to a GP center where eggs collected from each poultry farm are centrally processed according to the processing capacity of the egg processing equipment, in an in-line system eggs are transferred directly from the chicken house after laying. ,
Since the number of eggs laid varies from chicken house to chicken house and even during the day, and the amount of eggs supplied is uneven, a decrease in the operating rate of the egg processing equipment has been a problem. In addition, when the egg processing equipment starts or stops, the egg collection conveyor also operates at the same time, making it difficult to fully utilize the performance of the egg processing equipment. In addition, when the egg collection conveyor is stopped or started frequently due to changes in setup, etc., the egg collection conveyor is stopped and started, which is a major cause of broken eggs on the egg collection conveyor.

0004

[Means for Solving the Problems] Therefore, the present invention aims to minimize the transportation stoppage of the egg collection conveyor and to efficiently supply eggs to the egg processing device. A method for controlling an egg collection and processing system comprising a main line conveyor for transporting eggs and a plurality of branch conveyors for causing eggs to flow into the main line conveyor, in which a signal to start or stop operation issued from the egg processing device is received, Provided is an egg conveyance control method that identifies a plurality of classified signal types from a signal and controls the main line conveyor and the branch line conveyor in accordance with the type, and also utilizes this egg conveyance control method. In the control device of the egg collection and processing system, an identification means is provided for receiving an operation start or operation stop signal issued from the egg processing device and identifying a plurality of classified types of the signal from the signal, An egg conveyance control device is provided, which is provided with a control means for controlling the main line conveyor and the branch line conveyor in accordance with the type identified by the identification means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained based on the drawings. FIG. 1 illustrates the egg collection and processing system of this embodiment. There are two cages in each chicken house 1a, 1b, and 1c.
The cages 2 are stacked in three tiers, and a plurality of rows of cages 2 of these three tiers are arranged in one row. In front of this row of cages, branch conveyors 4a, 4b, and 4c are provided corresponding to each cage 2 and serve as egg collection conveyors for receiving chicken eggs 3 and transporting them to the sides of the chicken house. There are thus three branch conveyors (parts of the branch conveyors of the other rows are shown in dashed lines in FIG. 2). An escalator 5 is provided at the discharge end of these branch conveyors 4a, 4b, 4c to transfer the transferred eggs 3 downward. In the poultry houses 1a, 1b, and 1c, cages 2 are arranged in multiple rows, and escalators 5 are also arranged in a number corresponding to the cage rows (in Fig. 1, cage rows and escalators 5 are arranged in each poultry house. (Only one row of escalators is shown. Also, escalator 5 is not shown in Fig. 2.)
.

The eggs 3 transferred downward by the escalators 5 are transferred to a main conveyor 7 connected to an egg washing and sorting device 6, which is provided with the side surface of the conveyance path facing the discharge end of the escalator 5. Further, at the discharge end of the escalator 5, a general limit switch or a photocell is installed to count how many eggs 3 sent by the branch conveyors 4a, 4b, and 4c have transferred to the main conveyor 7. counters 8a, 8b, and 8c are provided. The eggs 3 transferred by this main line conveyor 7 are sent to an egg washing and sorting device 6. The branch line conveyors 4a, 4b,
4c and escalator 5 are branch line motors 9a, 9b, 9c.
Also, the main line conveyor 7 is driven by a main line motor 10. Further, the branch line motors 9a, 9b, 9c and the main line motor 10 have speed detectors that detect the conveyance speeds of the branch line conveyors 4a, 4b, 4c and the main line conveyor 7, respectively.

[0007] There is an introduction part 11 at the entrance of the egg washing and sorting device 6, and the eggs 3 that have been transferred in a lump are passed through this introduction part 1.
The eggs 3, which are dispersed in rows 1 and generally in six rows, are aligned by a direction alignment device 12 so that they face in the same direction with their long axes lateral. After that, the eggs pass through an egg washing device 13, a drying device 14, and are canted in an egg checking device 15.
The eggs are transferred to a distribution conveyor 16 to be sorted according to their size.

Further, near the egg washing and sorting device 6, a branch conveyor 4a is installed based on various operation signals from the egg washing and sorting device 6.
, 4b, 4c and a control device 17 for controlling the conveyance of the main line conveyor 7.

As shown in FIG. 3, this control device 17 receives an operation start or operation stop signal sent from the egg washing and sorting device 6, and determines whether this signal is an operation preparation preset as the type of signal. An identification unit 18 that identifies which signal (hereinafter referred to as “type signal”) is the signal f, operation signal g, work end stop signal h, or temporary stop signal i, and the type signal identified by this identification unit 18. , selectively for the main line motor 10 and each branch line motor 9a, 9b, 9c in response to the speed signals of the main line motor 10 and each branch line motor 9a, 9b, 9c, and counting signals from each counter 8a, 8b, 8c. A control unit 19 that outputs a speed signal, and a storage unit 20 that stores distance information from the inflow point from each branch conveyor 4a, 4b, and 4c of the main line conveyor 7 to the introduction part 11 of the egg washing and sorting device 6. , based on the type signal from the identification unit 18 that is input to the control unit 19, the speed signal of the main motor 10, the number of eggs flowing from the branch conveyors 4a, 4b, 4c to the main conveyor 7, and the distance information. , a calculation unit 21 that selectively calculates new speeds for the main line motor 10 of the main line conveyor 7 and the branch line motors 9a, 9b, 9c of each branch line conveyor 4a, 4b, 4c.

[0010] Upon receiving a signal to start or stop operation from the egg washing and sorting device 6, which has the ability to process 20,000 eggs per hour, the type signal is identified and the calculation unit 21 calculates the type signal each time. Main line conveyor 7 and branch line conveyor 4a
, 4b, 4c as an example, the control procedure is shown below. It is assumed that each of the branch conveyors 4a, 4b, and 4c can supply 10,000 eggs per hour.

The operation preparation signal f, which is a type of the operation start signal, is a command signal to make a group of eggs stand by in the introduction section 11, and even if this signal is set in the egg washing and sorting device 6, the egg washing and sorting device 6 Not working. Another type of operation signal g is an operation start signal for operating the egg washing and sorting device 6. Further, the work end stop signal h as a type of operation stop signal stops the egg washing and sorting device 6, and also stops the main line conveyor 7,
The branch conveyors 4a, 4b, and 4c are stopped. Another type of temporary stop signal i is a type signal that is issued when the egg washing and sorting device 6 has stopped. , 4c do not stop immediately but are decelerated.

When the egg washing and sorting device 6 issues an operation preparation signal f, which is an operation start signal, as a type signal, this type signal is sent to the identification section 18 of the control device 17. The identification section 18 identifies the input type signal, and if it is determined to be the operation preparation signal f, the operation preparation signal f is sent to the control section 19 . Based on the input operation preparation signal f, the control unit 19 controls the main line conveyor 10 in response to the operation preparation signal f.
and control the branch conveyors 4a, 4b, 4c. In other words, the control commands for the branch conveyors 4a, 4b, and 4c are to satisfy the throughput of the egg washing and sorting device 6, and 20,000 pieces per hour.
is selected, the eggs 3 are transported to the introduction section 11 of the egg washing and sorting device 6, and are kept on standby.

Hereinafter, the control operation in response to the operation preparation signal f in the control section 19 will be explained based on the flowchart of FIG. The distance from the branch conveyor 4a of the chicken house 1a to the introduction part 11 of the egg washing and sorting device 6 is La, the distance from the branch conveyor 4b of the chicken house 1b to the introduction part 11 is Lb, and the chicken house 1
If the distance from the branch conveyor 4c of c to the introduction part 11 is Lc, in order to supply 20,000 eggs 3 per hour,
The branch conveyor 4a of the poultry house 1a and the branch conveyor 4b of the poultry house 1b are selected (step S1), and first the main conveyor 7 is selected.
main line motor 10 and branch line motor 9 of branch line conveyor 4b
A drive signal is output to b (step S2).

[0014] In response to this drive signal, the main line motor 10 and the branch line motor 9b start slowly. The number of eggs supplied from the branch conveyor 4b to the main conveyor 7 is
It is counted by the counter 8b of b, and this counting signal is sent to the control section 19. The calculation unit 21 calculates the timing as to whether the first egg group supplied from the branch conveyor 4b to the main conveyor 7 has been conveyed to the branch conveyor 4a. This timing is calculated by the calculation unit 21 based on the conveyance speed signal from the main motor 10, (Lb-La)
/(speed of main line conveyor 7) obtained from the calculation result of (
Step S3).

When the first egg group is conveyed to the branch conveyor 4a of the poultry house 1a (step S4), a slow start drive signal is sent from the control unit 19 to the branch motor 9a of the branch conveyor 4a ( Step S5). By driving the branch line motor 9a, the main line conveyor 7
In addition to the egg group above, eggs are supplied from the branch conveyor 4a. As mentioned above, when each conveyor starts,
The drive starts slowly to reduce the impact of the eggs on the conveyor. During this time, the speed of the main line conveyor 7 is gradually increased along with the movement of the branch line conveyors 4b, 4a and these branch line conveyors 4b, 4a.

[0016] When it is determined that the head of the egg group has reached the introduction section 11 from the value of the calculated transport elapsed time (step S
6) In order to slow down and stop the branch line conveyors 4b, 4a and the main line conveyor 7 over a preset period of time, the branch line motors 9b, 9a and the main line motor 10 are activated.
A stop signal is output to control the conveyance stop (step S7). The above operations are preliminary preparations for efficiently operating the egg washing and sorting device 6.

Next, a control procedure will be described based on the flowchart of FIG. 5 in the case where the identification section 18 identifies that the operation signal g of the operation start signal has been issued as the type signal. If it is determined that the driving signal g
is input to the control section 19. The control unit 19 drives the main line conveyor 7 and the branch line conveyors 4a, 4b at a slow start based on the input operation signal g (step S
8). In order to process 20,000 eggs per hour,
The conveyance speed of the main line conveyor 7 and branch line conveyors 4a, 4b is gradually increased. In this case, the upper limit of the conveyance speed of the branch conveyor can be determined in advance.

[0018] In order to maintain the supply amount such that the total number of eggs 3 counted by the counters 8a and 8b is equal to 20,000 per hour at a speed that does not break the eggs 3 during transportation, The supply amount is determined by the speed signals from the main conveyor 7 and the branch conveyors 4a, 4b and the counters 8a, 8b.
(Step 9). It is determined whether the calculated supply amount is comparable to the supply amount (step S10), and if it is less than the supply amount, a branch line conveyor of another poultry house, for example, a branch line of the poultry house 1c, is newly added. A conveyor 4c is added to supply eggs to the main conveyor 7. Further, after the supply of eggs from the branch conveyors 4a and 4b, for example, if the supply amount of eggs from the branch conveyor 4a decreases, the branch line of the branch conveyor 4c is The motor 9c is driven (step S11). In response to the count signal sent from the counter 8c, the conveyance speed of the branch conveyor 4c is accelerated until the required number of pieces can be supplied. As a result, a supply of 20,000 eggs per unit time is maintained.

These calculations for conveyance control are carried out by the calculation section 2.
1 is executed. Specifically, the calculation unit 21 performs the following calculations. Branch conveyor 4a, 4
The supply of eggs from b is less than 20,000 eggs per unit time1
．． If it decreases to 50,000 pieces, (20,000 - 15,000 = 0,500)
That is, unless 5,000 eggs are newly supplied, the processing efficiency of the egg washing and sorting device 6 will decrease. Therefore, in order to maintain the supply amount of 20,000 pieces, the branch conveyor 4c is selected from among the branch conveyors stored in the storage unit 20, and a drive signal is output from the control unit 19 to the branch line motor 9c of the branch line conveyor 4c. Ru. The selected branch conveyor 4c starts slowly and gradually increases its speed. The number of eggs supplied from the branch conveyor 4c to the main conveyor 7 is determined by a counter 8c.
If it is determined that the conveyance speed is equivalent to 5,000 pieces per unit time from the count signal input per unit time and the conveyance speed of the branch conveyor 4c at that time, then this conveyance speed is A control signal is output from the calculation section 21 to the branch motor 9c via the control section 19 in order to maintain the condition.

By the way, in the case of the operation signal g, when this operation signal g is input to the control section 19, it is first checked whether the pre-operation preparation has been completed or not, that is, whether or not the eggs have been transferred to the introduction section 11 of the egg washing and sorting device 6. If the preparatory preparations have not been completed yet, the egg washing and sorting device 6 is not operated and the process proceeds to step S1.
Jump to , complete the preliminary preparations, and the eggs are already in the introduction section 11.
The controller 19 may be provided with a function of operating the egg washing and sorting device 6 when the egg washing and sorting device 6 reaches the point where the egg washing and sorting device 6 is on standby.

As another embodiment, a case will be described in which the procedure for controlling the conveyance speed of the main line conveyor and the branch line conveyor is set in advance as a control pattern. In the case of this embodiment, as shown in FIG. 6, six branch line conveyors 23 to 28 face the main line conveyor 22, and the distance L to the introduction part 29 of the egg washing and sorting device 6 is The same applies to the branch conveyors 23 to 28. In addition, this numerical value (hereinafter referred to as "unit time processing amount") is set in the egg washing and sorting device 6 in order to process 20,000 eggs per hour, and each branch conveyor 23 to 28 is set to the maximum value. Assume that 10,000 eggs can be supplied per hour. In addition, the main line conveyor 22 and each branch line conveyor 23 to 28 are driven by a main line motor 30 and branch line motors 31 to 36, and at the discharge end of each branch line conveyor 23 to 28, a known method is used to count the number of eggs supplied to the main line conveyor 22. counting counter 37
~42 are provided.

As shown in the electrical block diagram of FIG. 7, the control device 43 of this embodiment receives the operation start or operation stop sent from the egg washing and sorting device 6, and selects this signal as the type of signal. An identification unit 44 that identifies which type of signal is a preset operation preparation signal, operation signal, work completion stop signal, or temporary stop signal, and the main line conveyor 2
2, a storage unit 45 that stores control patterns for controlling the branch conveyors 23 to 28 in correspondence with the type signals, and a setting attached to the control device 43 that sets a control pattern in the storage unit 45 for each type signal. section 46 and the main line motor 3 of the main line conveyor 22 based on the control pattern retrieved from the storage section 45 in response to the type signal.
0 and the branch motors 31 to 28 of the branch conveyors 23 to 28
The control section 47 outputs a control signal of a selected control pattern to the control section 36.

The control pattern executed by the control section 47 when an operation preparation signal as an operation start signal is issued from the egg washing and sorting device 6 will be explained based on the flowchart of FIG. In order to satisfy the unit time throughput value set in the egg washing and sorting device 6, six branch line conveyors 23 to 2 are used.
The setting unit 46 has already set which of the branch conveyors 23 to 28 to be selected and combined.

In this embodiment, since up to 10,000 pieces can be supplied per hour, two branch conveyors 23, 24,
Branch line conveyors 25, 26, and branch line conveyors 27, 28
are driven in pairs, and the eggs are supplied to the main conveyor 22. From the control unit 47 to the branch conveyor 23, 2
A drive start signal is output to each of the branch line motors 31 and 32 of the main line conveyor 22 and to the main line motor 30 of the main line conveyor 22 (step S20). At this time, each branch conveyor 23
, 24 is controlled to start slowly and gradually accelerate.

The number of eggs sent from the branch conveyors 23, 24 to the main conveyor 22 is
4 is counted by counting counters 37 and 38 provided at the discharge end of the pump 4, and sent to the control section 47 of the control device 43. Based on the first counting signals sent from the counters 37 and 38, the subsequent conveyance speed of the main line conveyor 22, and the distance L to the introduction section 29, the head of the egg flock transferred to the main line conveyor 22 is located at the introduction section 29. The time to reach is calculated. When it is determined that the head of the egg group has reached the introduction part 29 from the calculated value of the elapsed transportation time (step S21),
Over a preset period of time, the branch line conveyor 23,
In order to slow down and stop the main line conveyor 24 and the main line conveyor 22, a stop signal is output to the branch line motors 31, 32 and the main line motor 30 to control the conveyance stop (step S22). The above operations are preliminary preparations for efficiently operating the egg washing and sorting device 6.

The flowchart in FIG. 9 illustrates the control procedure of the control pattern for the operation signal. When the operation signal of the egg washing and sorting device 6 is input to the control device 43, a control pattern corresponding to the operation signal is selected in the storage section 45. Based on the selected control pattern, the control unit 47 determines whether pre-operation preparations for efficient processing have been completed, that is, whether or not a group of eggs is in the introduction section of the egg washing and sorting device 6, and If the preparations have not been completed yet, the egg washing and sorting device 6 is not operated, and the process jumps to step S20 to complete the preliminary preparations (step S23).

If the eggs have already arrived at the introduction section 29 and are waiting, the egg washing and sorting device 6 is operated, and the main line conveyor 22 and branch line conveyors 23, 24 are driven at a slow start (step S24). . Then, in order to process the eggs of the unit time throughput, the conveyance speed of the main line conveyor 22 and the branch line conveyors 23, 24 is gradually accelerated, and when the count signals from the counters 37, 38 reach the numerical value of the unit time throughput, Supply to the egg washing and sorting device 6 is continued while maintaining the conveyance speed at that time.

[0028] Then, it is determined whether eggs have been supplied from all of the branch conveyors 23 to 28 (step S25),
If the supply of eggs has been completed, the main line conveyor 22 and the branch line conveyor currently being driven are slowed down over a certain period of time and then stopped (step S26). If the supply is still continuing, it is determined whether the supply amount has decreased and is below the processing capacity of the egg washing and sorting device 6 (step S27), and if it is below, the next branch conveyor 25, 26 is A drive signal is output to the branch line motors 33 and 34 to slow start the branch line conveyors 25 and 26, and the branch line conveyor 2 is started based on the counting signals from the counters 39 and 40.
5 and 26 are controlled. That is, the speeds of the branch conveyors 25 and 26 are controlled in order to set the conveyance speed at which the quantity of eggs supplied from the branch conveyors 25 and 26 is insufficient for the unit time processing amount (step S28). And all branch line conveyors 23-2
Steps S25 to S28 are repeatedly executed until the supply from step 8 is completed.

When the egg washing and sorting device 6 is stopped for some reason, such as a stop due to a factor that is expected to recover immediately, during operation of the egg washing and sorting device 6, the operation stop signal type is A pause signal is sent to control device 43. The control procedure of the control pattern for the temporary stop signal is illustrated in FIG. That is, the main line conveyor 22 and the branch line conveyors 23, 24 are gradually decelerated and conveyed (step S29). Even after the preset time has passed,
If the restart signal is not input (step S30),
Gradually decelerate again and pause (step S31)
.

[0030] If a restart signal is input within a preset time and if a restart signal is issued from the egg washing and sorting device 6 after step S31, in step S30, the main line conveyor that has been decelerated is 22 and the branch conveyors 23, 24 are again accelerated to a speed that supplies the unit time throughput. While the egg washing and sorting device 6 is stopped, the eggs 3 supplied to the egg washing and sorting device 6 are transferred to the introduction section 11.
surplus is retained. Therefore, in the control unit 47, the supply amount of eggs transferred to the introduction unit 29 during the time when the egg washing and sorting device 6 was stopped is determined based on the time during which the egg washing and sorting device 6 was stopped, the conveyance speed of the main line conveyor 22, The main line conveyor 22 is calculated from the counting signals from the counters 37 and 38 and is decelerated.
Until the egg supply capacity is increased to the unit time processing amount, the conveyance speed of the main line conveyor 22 is gradually changed in order to efficiently process the eggs accumulated in the introduction section 29 and to prevent eggs from breaking due to impact. (step S32). Then, the process jumps to step S25 and control continues.

[0031] When the egg washing and sorting device 6 finishes processing eggs or stops for a break time, etc., a work end stop signal is issued as a type of operation stop signal. When the identification unit 44 identifies this type signal as a work end stop signal, the storage unit 45 selects a control pattern corresponding to this type signal stored in the storage unit 45. Control unit 4
At step 7, the conveyance of the main line conveyor and the branch line conveyor is controlled based on the selected control pattern. That is, as shown in FIG. 11, a stop signal is output to the main line conveyor 22 and the branch line conveyors 23 to 28 that are being driven (step 33).
), slows down over a certain period of time, and then stops (step 34).

By the way, in order to supply eggs on average, depending on the number of eggs supplied from each branch conveyor 23 to 28, the branch line conveyor with a small number of eggs is conveyed at a high speed, and the branch line conveyor with a large number of eggs laid is conveyed at a low speed. By doing so, the eggs can be uniformly supplied to the egg washing and sorting device 6.

As another example, when selecting a branch conveyor as an egg collection conveyor provided in each chicken house,
Red eggs and white eggs may be controlled separately as egg types.

Furthermore, the egg processing device of the egg collection and processing system may be a so-called farm packer, which is an egg processing device that collects laid chicken eggs transported in-line from a chicken house into a container.

[0035] The egg processing device connected to the main line conveyor is
As already described, it may be an egg washing and sorting device or a collection device that does not perform processing such as egg washing and sorting, and the processing request input from the egg processing device to the transfer control device is based on the type of egg. and the size sorting process,
If the egg shell color or other type-specific collection treatment,
Conveyance on the main line conveyor and branch line conveyor is controlled based on these processing requests.

Further, the conveyance control device has means for separately storing average egg weight information, egg weight distribution information, and other type information of eggs supplied from each branch conveyor to the main conveyor for each branch conveyor, The conditions required by the egg processing device may be added to the number of eggs processed per unit time, and the above information may be added as a condition to determine the priority of transportation and generate an operation signal and a speed signal to each branch conveyor.

In the embodiments described above, the conveyance of the main line conveyor and the branch line conveyor is controlled, but only the main line conveyor controls the conveyance speed, and the conveyance of the branch line conveyor as an egg collecting conveyor facing the cage row is controlled. In some cases, the material is not controlled and is transported at a constant speed. In this case, the amount of eggs supplied to the egg processing device is adjusted by controlling the conveyance speed of only the main line conveyor. Alternatively, only a branch conveyor may be used.

[0038]

Effects of the Invention According to the present invention, the conveyance of the main line conveyor and the branch conveyor is divided into operation start and operation stop signals issued from the egg processing equipment, and the conveyance of the conveyor is controlled by dividing into a plurality of types. It is now possible to minimize stoppages, reduce shocks, safely, and efficiently operate eggs that are transported directly in-line from the chicken house to the processing capacity of the egg processing equipment. Furthermore, by controlling the conveyance differently depending on the signals, it was possible to realize soft-touch conveyance of the eggs during transfer.
