DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance management system for a packaging device used for packing articles to be distributed and sold.

[0002]

2. Description of the Related Art In many cases, various products to be distributed and sold are packed in small units in cardboard boxes or the like, and the packages (packages) are often transported, unloaded and stored in palletized quantities. .

[0003] Palletized luggage is used for transportation, cargo handling,
During storage or the like, the collapse of the load is likely to occur, and during transportation or the like, the product may be wetted by rainwater or the like, or may be stained to lower the commercial value. Furthermore, there is a possibility that the cargo may be unloaded during storage. So recently,
The so-called stretch wrapping, in which a plastic film such as polyethylene is wrapped around a plurality of palletized luggage, is used to prevent the collapse of the luggage and to protect the luggage from rainwater, dirt, unloading, etc. I have.

As an apparatus for performing such stretch packaging, conventionally, a turntable on which luggage is loaded, a carriage on which a film feeding roller is mounted, a mast for supporting the carriage, and a carriage which is vertically moved along the mast. With a lifting mechanism to move the film, set the film roll on the carriage, put the palletized luggage on the turntable, rotate the turntable, feed out the film to the side of the luggage, and raise and lower the carriage There is a turntable type stretch wrapping machine that spirally winds a film around palletized luggage (for example, Japanese Patent Publication No. 59-940).
No. 3).

[0005] As another stretch wrapping machine, a fixed table on which a load is placed, a carriage on which a feeding roller for feeding a film is mounted, an arm for rotating the carriage around the side of the load, and an elevating device for moving the carriage up and down. With a mechanism, with the palletized luggage placed on the fixed base, the film is fed out to the side of the luggage while rotating the carriage around the side of the luggage, and the carriage is raised and lowered, so that the palletized luggage is There is an arm-rotation type stretch wrapping machine that winds a film in a spiral shape (for example, JP-A-8-156908).

[0006] When various kinds of products to be distributed and sold are packed in a cardboard box or the like, styrene foam chips are used as cushioning materials. However, styrene foam chips have a problem in incineration at the time of disposal. An air pad filled with air between films such as a polyethylene film has been commercialized as a cushioning material for packing that solves this problem.

[0007] As an apparatus for manufacturing such an air pad, a film (polyethylene film) fed from a film roll is fed at a constant pitch by a feed roller.
In this feeding process, the film is folded in two,
The mating surface (open end) of the film is welded with a heater (longitudinal welding) to form a film ring, and then air is introduced into the film ring along a direction perpendicular to the film feeding direction. Extending heater (lateral welding)
There is an apparatus that obtains a single-row type cushioning material (air pad) by welding a film ring at every feed pitch (for example, Japanese Patent Application Laid-Open No. 8-216258).

Further, as another apparatus for manufacturing a cushioning material for packing, a plurality of vertical welding heaters arranged at a predetermined pitch along the width direction of the film, and a plurality of horizontal welding heaters arranged along the width direction of the film are provided. It is equipped with a directional welding heater, and feeds two films fed from two film rollers at a constant pitch by a feed roller. In this feeding process, in a state where the films are overlapped, a plurality of longitudinal welding heaters are used. Welding is performed to form a plurality of film rings arranged in the width direction of the film, and then, in a state where air is introduced into each film ring, the film is fed by a horizontal welding heater and welded at each pitch, thereby forming a plurality of films. There is a device for obtaining a row type cushioning material (air pad) (for example, Patent 258)
No. 6869).

[0009] In the above-mentioned packaging equipment such as the stretch packaging machine and the packaging cushioning material manufacturing equipment, the maintenance management such as the periodic inspection and the repair after the failure has occurred is performed by the service person on the manufacturer side by the user. I go to go.

[0010]

By the way, in the conventional maintenance management, a serviceman on the manufacturer side goes to the user and inspects the device to check whether or not there is a part which has exceeded the replacement time. If you order that part,
A method of replacing parts at a later date is adopted. However, such maintenance management is inefficient because it is necessary for a service person on the manufacturer side to visit the user twice. In addition, if there is no part beyond the replacement time, a service person's business trip may be wasted.

Further, the number of periodic inspections performed by a service technician varies depending on the frequency of use of the apparatus, but is at most several times a year. If a failure occurs during the periodic inspection, failure repair is required. It is necessary to stop the apparatus until it is completed, which reduces the efficiency of the packaging operation.

The present invention has been made in view of such circumstances, and allows a user to be notified of information such as inspection locations and parts replacement before a failure occurs, thereby preventing a sudden failure from occurring. It is an object of the present invention to provide a maintenance management system for a packaging device capable of performing the above.

[0013]

Next, when the inspection M2 is carried out as the maintenance management, the alarm history data stored in the controller 11 of the stretch packaging machine S1 is read, and the data is displayed on the display section DP of the personal computer C.

The operator determines from the displayed contents whether there are many trouble spots. If there are many trouble spots, a message to check the spots is sent from the manufacturer's personal computer C to the stretch packaging machine S1. The inspection location is transmitted to the controller 11 via the telephone communication system and displayed on the display 12a of the touch panel input device 12. By this processing, for example, a message as shown in FIG. 20 is displayed on the display 12a, and when such a display is found, the user checks the limit switches 23 and 24.

As described above, according to the maintenance management system of this embodiment, the user can be notified of information such as inspection points and parts replacement before a failure occurs in the stretch packaging machine S1. Can be prevented from occurring. Further, it is possible to reduce the number of times the service technician goes to the user to perform the inspection, or it is possible to omit the inspection on a business trip, so that the cost required for the maintenance management can be reduced. In addition, short intervals (eg twice a month)
Therefore, the degree of occurrence of a sudden failure can be greatly reduced as compared with the related art.

Here, as shown in FIG. 16, a system for connecting the controller 11 of the stretch wrapping machine S1 and the personal computer C on the manufacturer side via the portable telephones Ph1, Ph2 and the telephone communication system can be constructed. If this is the case, the following maintenance management is also possible.

By adopting such a system, the abnormality information can be transmitted directly to the manufacturer without the intervention of the user's worker, so that the user's worker can check the structure of each part of the stretch packaging machine. Even if the user is not familiar with the operation, the contents of the abnormal situation can be accurately grasped on the manufacturer side, and the return process can be completed in a short time.

Further, it is determined whether or not the generated device abnormality is an abnormality that can be recovered by the user on the user side.
Since the manufacturer can make the determination before performing the return operation, it is possible to eliminate unnecessary business trips of the maintenance worker.

For example, in the past, troubles that could be easily solved by a user on the user side, such as troubles caused by exhaustion of a memory backup battery in a controller and forgetting to turn on switches and the like required for operation, have occurred. In some cases, the maintenance worker is called by the user, but such useless business trips can be avoided.

Further, as other maintenance management, each process for coping with the occurrence of an abnormality in the controller 11 of the stretch wrapping machine S1 or for changing / updating the software of the controller 11 according to a user's request, etc.
It is also possible to construct a system in which the processing is performed by the manufacturer's personal computer C using the mobile phones Ph1 and Ph2 and the telephone communication system.
