[Conventional technology]

The packaging apparatus as described above is used for packaging spherical vegetables such as lettuce.

That is, in a state where the packaging sheet is supplied to the packaging means, the worker places the article to be packaged on the packaging sheet. Then, by starting the operation of the packaging means in this state, the packaging operation is performed.

Conventionally, a switch for instructing the start of the operation of the packaging means is provided, and the operator operates the switch. In this configuration, the operator operates the switch each time the packaging means is operated once. And there is a possibility that the operation is troublesome and the work efficiency is reduced. Therefore, in order to improve the above-mentioned drawbacks, there has been proposed a packaging apparatus in which, when an object to be packaged is supplied to a packaging means, the supply is detected and the packaging operation is automatically started (for example, see Japanese Patent Application Laid-Open No. Sho 63/1988). -138915
Reference).

[Problems to be solved by the invention]

However, in the above-described conventional technique, since it is not detected that the packaging sheet has been supplied to the packaging means, the packaging operation is started by erroneously supplying the article to be packaged while the packaging sheet is not supplied. As a result, there is a disadvantage that wasteful work is performed, and there is also a risk of damage to a packaged object such as a lettuce.

Therefore, in order to avoid such a problem, a device that detects whether or not a wrapping sheet has been supplied to the wrapping unit and automatically supplies the sheet to the wrapping unit if the sheet is not supplied may be considered. However, in this device, there is a risk that the sheet feeding device that operates to automatically feed the sheet at the time of start-up or the like may come into contact with an operator's hand or the like placed on the wrapping means, which is not preferable in terms of safety.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional drawbacks and to obtain a packaging device excellent in workability while performing packaging work appropriately and safely.

[Means for solving the problem]

In order to achieve this object, a first characteristic configuration of the packaging device according to the present invention includes a packaging sheet supply detection unit that detects whether the packaging sheet has been supplied to the packaging unit, A packaged object detection unit that detects whether the packaged object has been supplied, and a sheet supply command unit that instructs a sheet supply operation of the packaging sheet supply unit are provided. When the detecting means has detected that the packaging sheet has been supplied, the packaged object detection means detects the object to be packaged, and starts the operation of the packaging means. After the object to be packaged has been discharged, the packaging sheet supply means executes a packaging process for supplying the packaging sheet to the packaging means, and then stops the control operation, and the packaging sheet supply detection means When the non-supply of the wrapping sheet is detected, the wrapping sheet is supplied to the wrapping means by the wrapping sheet supply means as the sheet supply operation is instructed by the sheet supply instruction means. That is, the control operation is stopped after executing the sheet feeding process.

Further, the second characteristic configuration is provided with interruption instruction means for instructing an interruption instruction, wherein the control means detects that the packaging sheet supply detection means has supplied the packaging sheet, and
When the interruption instruction is instructed by the interruption instruction means, the control operation is stopped after the packaging means is operated, as the object to be packaged is detected by the object to be packaged detecting means. It is configured.

[Action]

In the first characteristic configuration, when it is detected that the packaging sheet has been supplied to the packaging means, when the worker supplies the packaged article in a state of being placed on the packaging sheet, the packaged article is supplied. Is detected, the wrapping means starts the wrapping operation of wrapping the wrapped object with the wrapping sheet, and after the wrapping operation is completed and the wrapped object is discharged, the wrapping means is wrapped by the wrapping sheet supply means. Then, a packaging process is performed in which the packaging sheet is supplied, and the process is stopped in a standby state in which the next packaged material is supplied. On the other hand, if it is detected that the packaging sheet is not supplied to the packaging means, and the sheet supply operation is instructed by the sheet supply instruction means, the packaging sheet is supplied to the packaging means by the packaging sheet supply means. And stops in a standby state waiting for the supply of the packaged object.

Further, in the second characteristic configuration, when it is detected that the packaging sheet has been supplied to the packaging means, and when the interruption instruction is instructed by the interruption instruction means, the operator places the packaging sheet on the packaging sheet. When an article to be packaged is supplied while being placed, the supply of the article to be packaged is detected, and the packaging means executes a packaging operation for packaging the article to be packaged with the packaging sheet and stops.

〔The invention's effect〕

In the first characteristic configuration, at the start of the packaging operation, etc.,
When the wrapping sheet is not supplied to the wrapping means, the wrapping operation is not performed until a sheet supply command is instructed. For example, in a device that automatically supplies a sheet when a sheet is not supplied, an automatic sheet supply operation is performed. May be in contact with the hands of workers placed on the wrapping means, which may not be desirable for safety. Therefore, the work can be started reliably, and at the same time, after the work is started, the packing work can be performed appropriately and smoothly only by supplying the material to be packed onto the packing sheet supplied in the previous packing process. A packaging device that can be executed and has excellent workability can be obtained.

Furthermore, in the second feature configuration, in the first feature configuration, only the packaging operation is executed by the interruption command,
Since the packing sheet can be set in a state where the packing sheet is not supplied to the wrapping means, for example, the operation can be completed in a state where the sheet is not supplied and the next operation can be smoothly started from the initial state. Then, the sheet size is switched in a state where the sheet is not supplied, and the operation can be resumed by the sheet supply command thereafter, so that a more convenient packaging apparatus can be obtained.
