Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a food production line system, and more particularly to a food production line system such as a lunch box in which mechanical equipment and manual work are mixed, and a control method therefor.
[0002]
[Prior art]
Since the present invention is an invention developed based on a publicly known / public technology (lunch box production line system) without conducting a prior art search, the prior art known by the applicant does not correspond to a known invention in the literature. . Hereinafter, the production line system of the well-known and public lunch boxes will be described.
[0003]
For example, in a food industry production line where food (rice, rice, etc.) is set (placed, aligned, cleaned of a predetermined container, etc.) in a container of a predetermined shape (hereinafter, referred to as a predetermined container), the predetermined container is used. The setting of cooked rice, prepared foods, and the like is not only performed manually, but also automatically performed using various types of machinery and the like, thereby improving production speed, productivity (production efficiency), and the like.
[0004]
FIG. 5 is a schematic explanatory diagram showing an example of a production line facility such as a general lunch box. In FIG. 5, reference numeral 51 denotes a means for setting a predetermined amount (or shape; for example, a substantially triangular prism shape or a substantially columnar shape) of main ingredients such as cooked rice (hereinafter, referred to as a main setting object) in a predetermined container. Hereinafter, it is referred to as a main setting means). The predetermined container in which the main setting object is set is moved to a means (hereinafter, referred to as a sub-setting means) 52 for setting other foods or the like (other than the main setting object; hereinafter, referred to as a sub-setting object). Then, various auxiliary ingredients are set in the predetermined container.
[0005]
The predetermined container in which all of the setting objects (main setting object and sub-setting object) are set as described above is conveyed to the wrapping means 53 and wrapped with a vinyl sheet, and also has a predetermined label (for example, used material, expiration date). , A label with the producer, etc.) is affixed, and the safety (eg, the presence or absence of dangerous materials such as metal parts) is checked via a metal detector, etc. Complete. Reference numeral 54 denotes a unit for sequentially measuring the number of completed products as described above (hereinafter, referred to as a number confirmation unit).
[0006]
In the main setting means 51 and the sub-setting means 52, for example, one or more workers sort out the main set object and the sub-set object stored in the tank by hand and set them in predetermined containers, or use mechanical equipment (for example, The main setting means 51 uses a shari molding machine or a shari separator capable of adjusting the operation rate) and sets the monitor under the monitoring of the worker. In addition, the above-mentioned worker performs the work of setting the main set target and the sub set target in a predetermined container while defining the type and amount of the main set target and the sub set target based on a command from a transmission means 58 such as an electric bulletin board in the processing facility. Do. Further, by connecting the above-mentioned respective means 51 to 54 via a transfer means (not shown) such as a belt conveyor, for example, while transferring the predetermined container in which the main setting object is set by the main setting means 51, Each sub-setting object can be set in the predetermined container by the sub-setting means 52.
[0007]
In recent years, the types of lunch boxes and the like required by consumers have increased, and for example, the types of lunch boxes and the like produced per day in one production line have also increased. On the other hand, as for the main set objects such as the above-mentioned lunches, common items are often set.
[0008]
For this reason, in a production line such as a lunch box as shown in FIG. 5, for example, a main set unit 51, a packaging unit 53, a quantity confirmation unit 54, a transfer unit, etc. For example, an operator (for example, an operator arranged along a production line) manually sets a sub-set on the predetermined container by using the sub-setting means 52. The target is set. The number of workers of the sub-setting means 52 is appropriately changed according to the type of the intended lunch and the like.
[0009]
In addition, in the main setting means, there is a form in which all is automated using mechanical equipment, etc., but there is also a form in which only a part is automated. For example, there is a mode in which a machine for continuously (automatically) manufacturing a fixed amount of a main set object is provided, and an operator sets the main set object to a predetermined container.
[0010]
[Problems to be solved by the invention]
In a production line such as a lunch box where machine equipment and manual work are mixed as described above, it is ideal that the operation rate of the machine equipment is set based on target production quantity, unit price, delivery date and the like. However, the setting may be changed according to the state of the production line.
[0011]
For example, in the case where a shari molding machine is used in the main setting means 51 of a production line such as a lunch box shown in FIG. 5, the operation rate of the sub-setting means 52 (for example, (For example, changes in the type of lunch, long-term continuous labor, work by unskilled workers, shortage of workers, low morale, excessive or insufficient set of foodstuffs, failure of transport means, etc.) When the supply of the predetermined container from the main set means 51 becomes excessive, the excess container is removed from the production line and removed from the production line at a predetermined location (for example, near the production line; (Referred to as means). In addition, even when a failure occurs in mechanical equipment such as the packaging means 53, the predetermined container is retained in the retaining means.
[0012]
When the number of the stored predetermined containers increases, the number of workers on the production line is increased, or, for example, the operation of each machine equipment (shape forming machine, transfer means, etc.) on the production line is determined by the workers. Is stopped. Then, after finishing the setting of the sub-set target for the retained predetermined containers, each machine facility is restarted before the operation stop or at a lower operation rate than before the operation stop.
[0013]
On the other hand, for example, the initial setting value of the operation rate (for example, the number of times the main set target is set per unit time) in the mechanical equipment of the main set unit 51 is too low, or the number of workers is too large for the type of the sub-set target. For such reasons, the operating rate of the sub-setting means 52 may be higher than the operating rate of the main setting means 51. That is, a situation in which more workers than the required number are put in the sub-setting means 52 may cause an increase in unit price. It is extremely difficult to objectively and accurately determine a change in the operating rate or productivity caused by the operator (for example, the user visually determines), as in the sub-setting means 52 described above. .
[0014]
In some cases, workers are put in the main setting means 51, the packaging means 53, the quantity checking means 54, etc., but the work is easier and the number of workers is smaller than that of the sub-setting means 52. There is almost no change in the operating rate or productivity due to the factor.
[0015]
Therefore, in a general production line such as a lunch box in which machine equipment and manual work are mixed and a set object (for example, a sub-set object) changes variously (frequently changes as compared with a production line such as an automobile), the worker It is difficult to determine a change in the operation rate or productivity caused by (particularly, an operator of the sub-setting means whose setting object changes variously), and a deviation occurs in the operation rates of the means 51 to 54. It is easy to repeatedly start and stop the machine equipment, and it is difficult to achieve the desired productivity (productivity in consideration of the unit price of the product). Such a phenomenon becomes more likely to occur particularly as the number of workers of the sub-setting means 52, in which the setting target changes variously, increases.
[0016]
The present invention has been made based on the above-mentioned problem, and in a production line in which machine equipment and manual work are mixed, for example, an operation rate of an operator is grasped based on an operation state of each machine equipment and the like, and a target production It is an object of the present invention to provide a food production line system and a control method thereof that facilitate the achievement of the food quality.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a food production line system and a control method thereof according to an embodiment of the present invention will be described in detail with reference to the drawings and the like.
[0032]
In the present embodiment, in a production line in which machine equipment and manual work are mixed, the operating rate of each machine equipment, the number of set predetermined containers and the like are read at predetermined time intervals, and based on the production conditions of the production line. In addition to calculating the productivity, the operator (especially, the operator of the sub-setting means whose setting object changes variously) reads the change in the operation rate or the productivity caused by the factor, and based on the result, the production line. Control (change) the operation rate of each machine and equipment.
[0033]
FIG. 1 is a schematic explanatory diagram illustrating an example of a food production line system according to the present embodiment. Note that the same components as those shown in FIG. 5 are denoted by the same reference numerals and the like, and detailed description thereof is omitted. In FIG. 1, reference numeral 55 denotes a connection (for example, I / O) to the main equipment 51, the auxiliary setting means 52, the packaging means 53, the number measuring means 54, and each machine used in the production line constituting the transfer means. It shows control means (for example, a personal computer) connected via a bus, a LAN line, or the like so that control commands, control responses, and the like can be transmitted and received.
[0034]
The control means 5 controls the operation status of each of the means 51 to 54 (for example, the operation rate of the transfer means, the operation rate of the mechanical equipment used by the main setting means 51, the number of products measured by the quantity confirmation means 54, It is assumed that it is possible to read the failure state of the mechanical equipment of the means 51 to 54) and control the operation rate of each mechanical equipment in the production line. Reference numeral 56 denotes operating means connected to the control means 55, and inputs the number of workers on the production line, types of main set objects and sub set objects, order quantities (quantities of products to be produced), and the like. (For example, inputting initial settings).
[0035]
Reference numeral 57 denotes a storage unit connected to the control unit 55, and can store data of each of the units 51 to 54 calculated by the control unit 5. The storage means 57 stores the production conditions of various products (for example, the order quantity of the target product, the number of workers to be input to each of the means 51 to 54 (especially the sub-setting means 52), and the production cost. The ideal productivity (hereinafter, referred to as ideal productivity (P)) and the ideal operation rate of each machine and equipment (hereinafter, referred to as ideal operation rate (Q)) suitable for the time, etc. Is preferred.
[0036]
Note that the ideal productivity P is obtained by producing (or producing on a trial basis) various products using various main set objects and sub-set objects while considering, for example, unit prices, labor costs, profits, and the like. The control means 55 reads the number of workers (M; in particular, the number of workers of the sub-setting means whose setting objects change variously), the number of products produced in a predetermined time (T), and the like. Based on the obtained data, for example, each productivity (hereinafter, referred to as actual productivity Pα) calculated by the following equation (1) can be considered. In addition, the ideal operation rate Q is the same as the ideal productivity P described above, and the various operation rates of each machine when producing (or producing on a trial basis) various products (for a predetermined container set per unit time). Quantity (N); hereinafter, referred to as the actual operation rate (Qα)), and can be calculated by, for example, the following equation (2).
[0037]
“Ideal productivity P” = “actual productivity Pα in consideration of unit price, labor cost, profit, etc.” = “Quantity N of products produced in predetermined time T” / (“number of workers M” × “predetermined time T ") ... (1)
“Ideal operating rate Q” = “actual operating rate Qα considering unit price, labor cost, profit, etc.” = “Quantity N of predetermined container to be set” / “predetermined time T” (2)
For example, the operating rate of the transfer unit corresponds to the number of predetermined containers transferred per unit time (one hour). Further, when rice is automatically set in a predetermined container by the main setting means 51 provided with a shari molding machine, the actual operation rate Qα of the main setting means 51 is such that the rice is set at a predetermined rate per unit time (one hour). This corresponds to the number of times set in the container. The main setting means 51 is provided with a machine for continuously (automatically) producing a fixed amount (amount set in one predetermined container) of cooked rice, and the operator sets the cooked rice in the predetermined container. In this case, the actual operation rate Qα of the main setting means 51 corresponds to the quantity of cooked rice (a fixed amount of cooked rice) per unit time (one hour). Further, most of the workers on the entire production line are related to the sub-setting means 52, and the operating rate and the productivity are particularly likely to change due to the workers of the sub-setting means 52. May be regarded as the number of workers of the sub-setting means 52.
[0038]
The transmission unit 58 transmits information such as a main set target and a sub-set target to be set in a predetermined container, a state of the production line, and the like to each worker of the production line (at least the worker of the sub-setting unit). For example, it can be transmitted by an electronic bulletin board or a sound.
[0039]
FIG. 2 is a schematic explanatory view showing an example of an operation process in the production line system of FIG. In FIG. 2, first, step S1 shows a production condition input step. For example, a target product, types of a main set target and a sub set target (settable target) of the product, Production conditions such as the number of workers to be input to each of the units 51 to 54 (particularly the sub-setting unit 52) of the production line, the target production quantity, and the time are input. Thereafter, in the calculation step shown in step S2, the input production conditions are compared with the data stored in the storage means 57, and are suitable for the production conditions according to the equations (1) and (2). The ideal operation rate Q of the machine equipment is calculated.
[0040]
Step S3 shows a command process, in which a command signal relating to the actual operation rate Qα is output to each machine (such as a sequence circuit of each machine), and the entire production line operates. Thereafter, step S4 shows an operation state confirmation / change step, in which the operation state of the production line is confirmed every predetermined time (T), and the production conditions, the actual operation rate Qα, and the like are changed as necessary. I do.
[0041]
The actual operation rate Qα at the start of the operation of the production line is preferably equal to or less than the calculated ideal operation rate Q. When the operation of the production line is started at the ideal operation rate Q, a large amount of predetermined containers move on the production line at the same time as the start, so that the retention is likely to occur. For this reason, it is preferable that the actual operation rate Qα at the start of the operation be obtained by subtracting a predetermined coefficient (X) from the ideal operation rate Q.
[0042]
Further, in the above-mentioned production condition input step S1, for example, when a part of the main set object and the sub set object for the target product is insufficient (for example, a part of the main set object and the sub set object is being prepared ( If it is insufficient during cooking), a complete product cannot be produced. In this case, first, the production conditions are input so that only the main set object and the sub set object that can be set are set in a predetermined container (hereinafter, referred to as a preliminary set), and the same process as the above-described calculation process S1 and command process S2 , A command signal relating to the actual operation rate Qα suitable for the above-mentioned spare set is output to each machine equipment. It is preferable that the actual operating rate Qα at the start of the operation of the spare set is also smaller than the calculated ideal operating rate Q of the spare set. After that, an insufficient set target is set in the pre-set predetermined container (hereinafter, referred to as a pre-set container).
[0043]
FIG. 3 is a schematic explanatory view showing an example of the operation of the control means 55 in the operation process of FIG. In FIG. 3, step S10 indicates a line state deficiency determination unit, and the presence or absence of a deficiency in the line state is confirmed in the production condition input step S1. Note that the above-mentioned deficiencies in the line state include, for example, a state where a part of the main set object and the sub set object cannot be set (for example, a state where the sub set object is being prepared (during cooking) and is insufficient) or a machine. When a part of the equipment is out of order (for example, a main set object and a sub set object can be set for a predetermined container, but the packaging means 53 is out of order and the label attaching operation cannot be performed), etc. Indicates when necessary.
[0044]
If there is no such deficiency, the operation processing unit of step S11 starts operation of the production line at the actual operation rate Qα obtained by subtracting the predetermined coefficient X from the ideal operation rate Q of the target product, and the predetermined time of step S12. The standby processing unit waits for a predetermined time T. After the lapse of the predetermined time T, the process shifts to the quantity confirmation processing section in step S13, where the product quantity N measured by the quantity confirmation means 54 during the predetermined time T is read. On the other hand, if the above-mentioned deficiency exists, the process proceeds to the partial setting processing unit (details will be described later with reference to FIG. 4) in step S14 to perform the preliminary setting.
[0045]
Step S15 shows the measurement quantity "0" determination unit. If the product quantity N at the above-mentioned predetermined time T is "0", an abnormality (stagnation or failure of mechanical equipment) occurs on the production line. Then, the process proceeds to the machine equipment stop processing unit in step S16, and the operation of each machine and the supply of the predetermined container are stopped. At the time of the stop, in a predetermined container in which the setting is not completed, the container is stored in, for example, a staying unit. Then, the process proceeds to the partial set processing unit S14 in order to set the remaining objects (hereinafter, referred to as a supplementary set) in the predetermined container (hereinafter, the stay set container) stored in the staying means.
[0046]
If the measured product quantity N is not “0”, the process proceeds to the productivity calculation processing unit shown in step S17, where the actual productivity Pα is calculated based on the above equation (1), and the storage unit 7 calculates the actual productivity Pα. To memorize. Thereafter, it shows the productivity comparison determination section in step S18, and compares the calculated actual productivity Pα with the previous value.
[0047]
As a result of the comparison, if the actual productivity Pα is equal to or more than the previous value, the process proceeds to the productivity increase determination unit in step S19. If the actual productivity Pα exceeds the previous value, the operation rate in step S20a is determined. The ascending processing section outputs a command signal to increase the operating rate Qα. On the other hand, if the actual productivity Pα is lower than the previous value, a command signal for lowering the availability Qα is output by the availability reduction processor of step S20b. The degree (g) of increase or decrease of the operation rate Qα is input in advance in the initial condition input step S1.
[0048]
Then, the continuous productivity determination unit α in step S21 continuously (two or more times) the actual productivity Pα and the actual operation rate Qα (or one of the actual productivity Pα and the actual operation rate Qα). It is determined whether it has risen, and if the rise is continuous, the process proceeds to an ideal value rise determination unit in step S22a. When the ideal value increase determination unit S22a determines that the actual operation rate Qα exceeds the ideal operation rate Q, the update processing unit of step S23a updates the actual operation rate Qα as the ideal operation rate Q. Then, it is stored in the storage means 57.
[0049]
On the other hand, when it is determined by the above-described continuous increase determination unit S21 that the increase is not continuous, the process proceeds to the productivity decrease determination unit in step S22b. If it is determined in the productivity decrease determination section S22b that the productivity is decreasing, the process proceeds to the update processing section in step S23b, and the actual operation rate Qα at the time when the decrease is determined is It is stored in the storage unit 7 as an optimum operation rate (hereinafter, referred to as an optimum operation rate (Qβ)) (if the optimum operation rate Qβ is stored in advance, it is updated and stored).
[0050]
In FIG. 3, in the case of the first operation from the start of operation, since there is no previous value regarding the actual productivity and the actual operation rate, the productivity comparison determination unit S18, the productivity increase determination unit S19, and the productivity continuous increase determination unit. In S21, it is preferable to determine that each has risen. In the quantity confirmation processing unit S13, only the quantity measured by the quantity confirmation means 54 is read. For example, a sensor capable of sensing a predetermined container is arranged at a predetermined location (for example, a staying means) of the production line. However, the case where a predetermined container is detected by the sensor may be determined as an abnormality of the production line.
[0051]
FIG. 4 is a schematic explanatory diagram showing an example of the operation of the partial set processing unit S14 in the control unit 55. In FIG. 4, step S141 indicates a preliminary / replenishment determination unit, and determines that the target operation is either a preliminary set or a supplementary set. If it is determined that the work is a compensation set, the process proceeds to the compensation set corresponding operation processing unit in step S143a, and the actual operation rate (Rα) lower than the ideal operation rate (R) suitable for the compensation set. The production line is started to operate, and operates in the same manner as the standby processing unit S12 to the update processing unit S23b for a predetermined time shown in FIG. The ideal operating rate R in the compensation set can be calculated, for example, by the following equation (3).
[0052]
“Ideal operating rate R” = “actual operating rate Rα considering unit price, labor cost, profit, etc.” = “Quantity N of stay set containers transferred from stay means to the production line” / “predetermined time T” ... 3)
On the other hand, if it is determined that the work is a spare set, the process proceeds to the measurement object change processing unit in step S142, and the object measured by the quantity confirmation unit 54 is defined to be recognized as a spare set container. Then, the spare line corresponding operation processing unit in step S143b starts operation of the production line at the actual operation rate (Vα) lower than the ideal operation rate (V) suitable for the spare set, and waits for the predetermined time shown in FIG. The operation is similar to that of the processing units S12 to S23b. The ideal operating rate (U) and the ideal operating rate (V) in the spare set can be calculated by, for example, the following equations (4) and (5).
[0053]
“Ideal productivity U” = “actual productivity Uα in consideration of unit price, labor cost, profit, etc.” = “Quantity N of spare set containers preliminarily set in predetermined time T” / (“number of workers M” × “ Predetermined time T ") (4)
“Ideal operating rate V” = “actual operating rate Vα considering unit price, labor cost, profit, etc.” = “Quantity N of predetermined containers set” / “predetermined time T” (5)
As described above, when the actual operation rate, the actual productivity, and the like are read and calculated at predetermined time intervals, for example, when the actual productivity continuously changes in a state where there is no failure of each machine or the like of the production line, Can be regarded as being caused by an operator (especially, an operator of the sub-setting means whose setting object changes variously). For example, when the actual productivity is continuously reduced without any failure of each machine or the like of the production line, a worker of the production line (particularly, a worker of a sub-setting means whose setting object changes variously). It is conceivable to increase the number of workers or to request the worker to increase the operation rate by the transmission means 58.
[0054]
[Example]
Next, based on the present embodiment, an attempt was made to produce a bento (product name; favorite lunch) using one of the production line systems owned by the applicant. In this embodiment, a certain amount (the amount set in one predetermined container) of cooked rice is continuously (automatically) manufactured by a shari molding machine provided in the main setting means 51, and the cooked rice is produced by one worker. Were sequentially set for the above-mentioned predetermined container. In addition, the sub-set objects are the set rice rice set (stretching), the meat set (and alignment, sauce), the pickles set, the cleaning of the dirt attached to the predetermined container (rimming), and the predetermined container. The lid was set (covered), and the sub-set target set was performed by 16 workers (the number of workers M was 17 in total).
[0055]
Further, as the wrapping means 53, one capable of automatically wrapping the above-mentioned predetermined container with a vinyl sheet and attaching a predetermined label was used. Furthermore, the ideal productivity P and the ideal operating rate Q (the number of times of producing a fixed amount of cooked rice per hour) in the target lunch stored in the storage means 57 are 1.373 and 1800, respectively. In addition, the degree g of increase or decrease of the actual operation rate Qα, the predetermined coefficient X, and the predetermined time T are set to 100, 400, and 3 minutes, respectively.
[0056]
First, the target lunch production conditions are inputted in the production condition input step S1, and the production line is started to operate at the actual operation rate Qα1400 through the calculation step S2 and the command step S3. The actual productivity Pα calculated by the calculation processing unit S17 was 1.275.
[0057]
Here, when the actual operation rate Qα is increased by 100 to 1500, the actual productivity Pα calculated by the productivity calculation processing unit S17 three minutes later (six minutes after the start of operation) is 1.294. , It was confirmed that the previous value was exceeded. At 9 minutes, 12 minutes, and 15 minutes after the start of operation, the actual operation rate Qα was increased by 100 to 1600, 1700, and 1800, respectively. The sex Pα was 1.333, 1.373, 1.450, respectively, and it was confirmed that the values exceeded the previous values.
