Description

  The present invention relates to a cargo handling work support system that supports cargo handling work.

  In recent years, various cargo handling work support systems that support cargo handling work using wireless communication have been developed. For example, in Patent Document 1, the management server assigns a plurality of cargo handling operations to a plurality of workers, and presents the assignment results to the workers via wireless communication.

  By the way, the contents of the cargo handling work are various. For example, certain cargo handling operations need to travel in narrow passages, while other cargo handling operations require loading and unloading of loads at high places, so that the contents of the cargo handling operations are different. Therefore, the cargo handling work has advantages and disadvantages depending on the content, and this differs depending on the worker.

  However, there is no support system that considers the pros and cons of cargo handling work. In fact, in Patent Document 1, a worker may be assigned a cargo handling operation that is not good for the worker, which may increase the burden on the worker. In addition, this may cause a reduction in the overall work efficiency.

  The forklift 1 can perform a manned operation in which the operator 5 gets on the driver's seat of the vehicle body 10 and operates the operation unit 12 and an unmanned operation in which the operator 5 automatically operates without operating the operation unit 12. The forklift 1 includes a mode switching unit 15 (switching switch) for the operator 5 to switch between manned operation and unmanned operation. The forklift 1 includes a display unit 16 (display) for displaying information, a storage unit 17 (storage medium) for storing necessary information, and a communication unit 18 (for wireless communication with the management server 3 via the communication network 4). Wireless module).

  The space in which the forklift 1 works is configured so that the forklift 1 can be operated unattended. For example, traveling of the vehicle body 10 in unmanned driving is performed by an image guidance method or a magnetic guidance method, and loading and unloading of a load by the fork 11 in unmanned driving is performed by a sensor, a rack, or the like provided in the fork 11. This is implemented by a mark or the like provided and detected by a sensor. Since these are well-known techniques, detailed description thereof is omitted.

  Further, the support system includes an operation information acquisition unit 19 for acquiring operation information of the forklift 1 in the forklift 1. In the embodiment, the operation information acquisition unit 19 acquires the work time of the forklift 1 as operation information. For this purpose, the operation information acquisition unit 19 includes a timer for measuring the work time.

  In this embodiment, the cargo handling work performed by the forklift 1 is moved to a certain work start location (for example, the first warehouse), and then loaded on the fork 11 and from there, the work finish location (for example, the second location) It means an operation from moving to a warehouse to transport the cargo and unloading the cargo from the fork 11 there.

  The support system includes a work detection unit (not shown) that detects the start and end of a cargo handling work in each forklift 1. The work detection unit includes, for example, a position detection unit (position detection sensor, GPS receiver, etc.) provided on the vehicle main body 10 for detecting that the forklift 1 has moved to the work start place and the work end place. In order to detect whether or not there is a load on the fork 11, the fork 11 includes a load detection unit (load sensor) or the like.

  As shown in FIG. 1, the ecological information acquisition unit 2 is a known wearable terminal attached to the worker 5, and is assigned to each worker 5. In the embodiment, the ecological information acquisition unit 2 acquires the heart rate of the worker 5 as ecological information. For this purpose, as shown in FIG. 3, the ecology information acquisition unit 2 includes a heart rate measurement unit 20 (heart rate measuring device) that measures the heart rate of the worker 5. The ecological information acquisition unit 2 includes a communication unit 21 for wirelessly communicating with the management server 3 via the communication network 4.

  The management server 3 includes, for example, a general-purpose computer, a program for executing processing to be described later, a storage medium for storing collected information, and the like.

  As shown in FIG. 4, the management server 3 includes a storage unit, and the storage unit includes a collection information storage unit 30 and a work storage unit 31. The management server 3 includes a control unit, and the control unit includes an allocation unit 32, a specifying unit 33, and a determination unit 34.

  The management server 3 collects information transmitted from the forklift 1 and the biological information acquisition unit 2 to the management server 3 via the communication network 4. The collected information storage unit 30 is for storing the collected information. Specifically, the operation information from the operation information acquisition unit 19, the work start / end information from the operation detection unit, and the ecology information from the ecology information acquisition unit 2 are stored and accumulated in the collection information storage unit 30. In addition, the collection information storage unit 30 includes the identification information of the worker 5, the identification information of the forklift 1 assigned to the worker 5, and the identification information of the ecology information acquisition unit 2 assigned to the worker 5. It is stored in association with each person 5.

  The work storage unit 31 stores information on all cargo handling operations that should be performed in a day for each day. The information on the cargo handling work includes a work start location, a work end location, a transport route from the work start location to the work end location, a package to be transported, and the like.

  There are multiple cargo handling operations with different contents. For example, some cargo handling operations need to travel in narrow passages, other cargo handling operations require loading and unloading of loads at high altitudes, and other cargo handling operations where the cargo is long, The cargo handling work is a work in the refrigerator and freezer. In the embodiment, cargo handling work having the same work start place, work end place, transport route, and type of package to be transported is defined as the same cargo handling work, and if at least one of these is different, it is defined as another cargo handling work.

  The assigning unit 32 assigns the cargo handling work to be performed on the day stored in the work storage unit 31 to each worker 5 working on the day. The assignment result is stored in the work storage unit 31. The assignment result of each worker 5 is transmitted to the forklift 1 assigned to the worker 5 via the communication network 4, stored in the storage unit 17 of the forklift 1, and further displayed on the display unit 16. It has become.

  The specifying unit 33 specifies a handling operation that each worker 5 is not good at based on the ecological information, the operation information, and the work start / end information stored in the collected information storage unit 30. Then, the determination unit 34 determines whether the cargo handling operation specified by the specifying unit 33 as being unsatisfactory for the worker 5 is assigned to the worker 5 by the assigning unit 32. The processing by the specifying unit 33 and the determination unit 34 will be described in detail below.

The management server 3 collects information necessary for specifying a poor cargo handling operation.
Each worker 5 wears the ecological information acquisition unit 2 (wearable terminal) and operates the forklift 1 to perform each cargo handling operation having different contents at least once. Information, work start / end information, and the like are transmitted to the management server 3 via the communication network 4, collected, stored in the collected information storage unit 30, and accumulated.

  The specifying unit 33 performs arithmetic processing using these pieces of information stored in the collected information storage unit 30 to obtain the work time in each cargo handling work of each worker 5. In the embodiment, the time measured by the operation information acquisition unit 19 between the time when the work detection unit detects the start of the cargo handling work and the time when the end is detected becomes the work time in the cargo handling work. When a certain worker 5 performs the same cargo handling work a plurality of times, an average of a plurality of times or the latest work time may be employed.

  The specifying unit 33 calculates an average value of the work times from the work times of a plurality of workers 5, preferably all the workers 5, in each cargo handling operation. In each worker 5 and each cargo handling work, the specifying unit 33 calculates whether the work time of the worker 5 in the cargo handling work is equal to or more than the above average value in the cargo handling work.

  In addition to the above, the specifying unit 33 performs arithmetic processing using the information stored in the collected information storage unit 30 to obtain the heart rate of each worker 5 during each cargo handling operation. In the embodiment, the heart rate measured by the ecological information acquisition unit 2 between the time when the work detection unit detects the start of the cargo handling work and the time when the end is detected becomes the heart rate at the time of the cargo handling work. When a certain worker 5 performs the same cargo handling work a plurality of times, the latest heart rate may be employed.

  The normal heart rate of each worker 5 is measured in advance as a reference heart rate, collected, and stored in the collected information storage unit 30. In each worker 5 and each cargo handling operation, the identifying unit 33 has a heart rate during the cargo handling operation of the worker 5 that exceeds the reference heart rate of the worker 5 by a predetermined number (for example, 10 bpm) and has exceeded this It is calculated whether or not the time is a predetermined time or longer (for example, 20 seconds or longer).

  Then, the specifying unit 33 determines that the work time in the cargo handling work of the worker 5 is equal to or greater than the average value of the work time in the cargo handling work, and that the heart rate of the worker 5 sets the reference heart rate during the cargo handling work. When a time exceeding several times continues for a predetermined time or more, the cargo handling work is specified as being unsatisfactory for the worker 5. On the other hand, if not, the specifying unit 33 specifies that the cargo handling work is good for the worker 5. This is because, when the worker 5 performs poor cargo handling work, the work time becomes longer, and the person feels stress, gets tired, or gets nervous, resulting in a normal heart rate. It is because it is known that it will rise. The identification result is stored in the collected information storage unit 30.

  For example, as shown in FIG. 5, when there are five cargo handling operations A to E having different contents, and there are four workers 5a to 5d, each worker 5a to 5d has good and bad points for each cargo handling operation A to E. A hand is specified by the specifying unit 33.

  The support system is provided with a support function for supporting the cargo handling work as follows by utilizing the fact that each worker 5 can identify the poor cargo handling work.

  When the support function is used, in the management server 3, the cargo handling work specified by the specifying unit 33 that the determination unit 34 is not good at the worker 5 is assigned to the worker 5 by the assigning unit 32. It is determined for each worker 5 whether or not there is. That is, it is determined for each worker 5 whether or not a plurality of cargo handling tasks assigned to the worker 5 include a cargo handling task that is not good for the worker 5. This determination is made based on the specific result stored in the collection information storage unit 30 and the allocation result stored in the work storage unit 31.

  For example, in FIG. 5, it is determined whether or not the cargo handling work C is assigned to the worker 5a, and whether or not the cargo handling work B and the cargo handling work D are assigned to the worker 5b is determined. In addition, unlike the worker 5c, there is a case where there is no poor handling work.

  When the determination unit 34 determines that a poor handling operation is assigned to the worker 5, the management server 3 uses the forklift 1 in which the worker 5 drives a support instruction including information on the poor handling operation. Are transmitted by wireless communication via the communication network 4.

  When the forklift 1 (the control unit 14) receives the support instruction from the management server 3, the forklift 1 (the control unit 14) stores the support instruction in the storage unit 17. Then, when the worker 5 finishes the cargo handling operation of driving the forklift 1, this is detected by the operation detection unit, and the order of performing the poor cargo handling operation comes, the forklift 1 performs the operation of the mode switching unit 15 and Regardless, the manned operation automatically switches to unmanned operation, and this unloading operation is carried out. That is, unfortunate cargo handling work is performed by the forklift 1 by unmanned operation. At this time, the display unit 16 displays that the forklift 1 performs a cargo handling operation in an unmanned operation and presents it to the operator 5.

  For example, in the case of the worker 5a in FIG. 5, the cargo handling operation C is performed by the unmanned forklift 1, and the other cargo handling operations A, B, D, and E are performed by the operator 5a operating the forklift 1. Will be.

  The forklift 1 stops after the completion of the cargo handling work, and switches to the manned operation automatically or by the operation of the mode switching unit 15 of the worker 5. Then, the operator 5 operates the forklift 1 to perform the next cargo handling operation. When the next cargo handling work is also poor, the forklift 1 also performs the next cargo handling work with unmanned operation.

  As described above, the present invention pays attention to the fact that the operation information of the forklift 1 and the ecological information of the worker 5 change when the worker 5 performs poor cargo handling work. Unloading work. When the worker 5 is assigned a cargo handling operation that is not good for the operator 5, the unloading forklift 1 performs the cargo handling operation. Therefore, the worker 5 does not need to perform poor cargo handling work, and the burden on the worker 5 is reduced. As a result, overall work efficiency can be improved.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment.

  In the above-described embodiment, the poor handling work is specified based on both the operation information and the ecological information, but may be specified based on only one of them.

  The work time in the cargo handling work is the time from the start to the end of the cargo handling work. Instead, the forklift 1 is actually operated by the operator 5 from the start to the end of the cargo handling work. It may be the time you have. In this case, the operation information acquisition unit 19 detects rotation of the sensor (operation lever, potentiometer that detects operation of the steering handle, and hydraulic motor) that detects that the operation unit 12 is operated or the drive unit 13 is driven. (Including an encoder for detection). Then, a maneuvering time during which the worker 5 actually steers the forklift 1 during the cargo handling work is measured by a timer, and this maneuvering time is set as a work time in the cargo handling work.

  The operation information may be power consumption of a battery that is a drive source of the forklift 1. In this case, the operation information acquisition unit 19 includes a power consumption measurement unit (power consumption measurement sensor) that measures the power consumption of the battery of the forklift 1. The specifying unit 33 calculates the power consumption in the cargo handling work of the worker 5 in each worker 5 and each cargo handling work, and calculates the average value of the power consumption in the cargo handling work of the plurality of workers 5. When the power consumption of 5 is equal to or greater than the average value, the cargo handling operation is specified as being unsatisfactory for the operator 5. This is because, when carrying out poor cargo handling work, the work time becomes long or the fork 11 is operated many times, resulting in an increase in power consumption in the cargo handling work.

  The ecological information may be the sweating amount of the worker 5. In this case, the ecological information acquisition unit 2 includes a perspiration amount measurement unit (perspiration amount measurement sensor) that measures the amount of sweat generated by the worker 5. For example, the sweating amount measurement unit is provided in the operation unit 12 of the forklift 1 and measures the amount of sweat of the palm of the worker 5 or is attached to a predetermined part of the body of the worker 5 and Measure the amount of sweat. The identifying unit 33 identifies that the cargo handling work is not good for the worker 5 when the amount of sweat in the cargo handling work of the worker 5 is greater than or equal to a predetermined amount. This is because the operator 5 tends to sweat more than usual when carrying out poor handling work.

  The biological information may be the body temperature of the worker 5. In this case, the ecology information acquisition unit 2 includes a body temperature measurement unit (thermometer) that measures the body temperature of the worker 5. The specifying unit 33 specifies that the cargo handling work is not good for the worker 5 when the time during which the body temperature of the worker 5 exceeds a predetermined value or more continues for a predetermined time or more during the cargo handling work. This is because the body temperature of the worker 5 tends to rise more than usual when carrying out poor cargo handling work.
