[Prior Art]

 Conventionally, when applying an undercoat material for the purpose of protecting the lower surface of the vehicle body, etc., to prevent the undercoat material from adhering to the screws and screw holes formed on the vehicle body, A mask piece made of tape or foam material is attached, and then an undercoat material is applied.

All of the above work is performed manually, and the worker attaches a tape or a mask piece to each screw hole or the like on the lower surface of the vehicle that flows overhead on the application line. It is troublesome.

Therefore, in order to reduce such trouble as much as possible, a masking material mounting device described in Japanese Utility Model Laid-Open No. 3-3480 is known as a device for mounting a mask piece.

In this device, a cylindrical case having an inlet and an outlet is filled with a plurality of mask pieces having fitting recesses in a stacked state, and the case is provided with a lever-like delivery for delivering the mask pieces to the outlet side. Means is provided. Therefore, each time the delivery means is operated to attach the mask piece at one end of the case to the vehicle body, the delivery means feeds one mask piece at a time to attach the mask piece to the vehicle body.

[0006]

However, in the conventional masking material mounting device described above, although the mask pieces can be sequentially mounted on the vehicle body side, the mounting work itself is performed manually. It was Therefore, when trying to automate this mounting work and using this device as it is to perform work using something like a work robot, it is necessary to move each case holding the mask piece. Therefore, a large output is used as the driving means, and the movement is limited, and even if the number of mask pieces that can be held in one case is limited, the mask piece is replenished on the way. It is not suitable for automation due to the need.

Therefore, the applicant has proposed a device that does not hold a large number of mask pieces by itself, but holds one mask piece at a fixed position and attaches it to the vehicle body (separate application). In this case, a device that constantly supplies mask pieces to this device one by one is required.

The present invention has been made based on the above problems and requirements, and provides a novel device capable of continuously supplying mask pieces one by one, thereby achieving automation of mask piece attachment. The purpose is to improve the work environment and work efficiency.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the masking piece supply device of the present invention is

[0010]

[Action]

 When supplying mask pieces, first, a case in which a plurality of mask pieces are stored in a stacked state is held on a base.

Then, the take-out mechanism is operated to take out the mask piece arranged at the other end of the case and move it to the delivery section of the transfer means.

Next, the transfer means is operated to transfer the mask piece from the sending section to the receiving section. In this way, the mask pieces sent to the receiving section can be used one by one.

Further, while the transfer means is being operated, the mask piece moving mechanism is operated to move one mask piece in the case from one side of the case to the other side, and the next takeout is performed. The mask piece is placed at the end of the case in preparation for. The above operation is sequentially repeated.

As described above, since the mask pieces are sent to the receiving section one by one, when the work robot attaches the mask pieces to the vehicle body, the work robot itself holds many mask pieces. It is not necessary, and automation can be achieved.
