Description

  The present invention relates to a carpet module folding and holding device that folds and holds a carpet module, and a carpet module loading device that loads the folded carpet module into a vehicle interior.

  For example, in order to carry a floor mat (carpet) into a passenger compartment of a body that is sequentially transported in an automobile production line, an operator folds the floor mat in two or four and holds the corner of the floor mat. It was carried in manually from the front door opening.

  However, in the method in which the operator holds the floor mat in his / her hand and carries it into the room, the larger the vehicle body becomes, the larger the floor mat becomes and its weight increases. Become. In particular, when the floor mat is folded in four, the floor mat is likely to be wrinkled, and the wrinkle remains even after being laid on the floor.

Then, the carrying-in apparatus which carries in a floor mat into a vehicle interior using a mechanical means is proposed (for example, refer patent document 1). In this carrying-in apparatus, a floor mat folded in half on a dedicated pallet is inserted between a plurality of mat gripping shafts, and the floor mats are mounted with a plurality of needles that can be moved in and out of the mat gripping shafts. The floor mat is carried into the vehicle interior from the front opening of the body where the windshield is attached by a separately provided transport device, and the needle is retracted when the floor mat has completely entered the vehicle interior.

In this fully contracted state, as shown in FIG. 17, the load of the carpet module 1 is applied to the operation lever 57, and the load is transmitted to the clamp portion 54 on one end side via the link rod inner 56 and the link rod outer 55. A strong clamping force for holding the carpet module 1 is generated.

  In the most contracted state, the stopper member 60 provided on the inner frame 53 is prevented from coming into contact with the end surface 52a of the main body frame 52 and the inner frame 53 is prevented from entering the main body frame 52 any more. Further, the one end portion 57 a of the operation lever 57 contacts the end portion of the link rod inner 56, and the link rod inner 56 is prevented from further entering the link rod outer 55. When the operation lever 57 hits the link rod inner 56, the load of the carpet module 1 is directly transmitted to the clamp portion 54 via the link rod inner 56 and the link rod outer 55.

  Therefore, as shown in FIG. 18, the carpet module 1 is lifted by the strong clamping force so as to hang down in a substantially U shape without dropping. Then, the raised carpet module 1 is transported into the passenger compartment 4 by the transport robot 5. After the carpet module 1 is transported into the vehicle compartment 4, as shown in FIG. 19, the carpet module 1 is lowered onto the floor panel 79 by aligning with the second cross member portion 78 as a reference.

  Then, the carpet module 1 spreads along the floor panel 79 as it is lowered, and the inner frame 53 and the link rod inner 56 naturally slide in the extending direction accordingly. After the mounting is completed, the carpet module 1 is removed from the operation lever 57, and the operation lever 57 is rotated in the counterclockwise direction indicated by the arrow A in FIG. The carpet module 1 can be gripped.

“Effects of Second Embodiment”
According to the present embodiment, since the carpet module 1 can be clamped from the work carriage 75 in the fully extended state with the inner frame 53 extended, it is possible to work alone, greatly reducing the man-hours and workability of the carpet mounting work. Can be improved.

  Further, according to the present embodiment, a mechanism that automatically expands and contracts the inner frame 53 and the link rod inner 56 using the load of the carpet module 1 itself is required, so a power source such as a special actuator is required. However, a simple and inexpensive device configuration can be obtained.

  Further, according to the present embodiment, the work carriage 75 can be supplied as it is from the carpet module sub-line 74 to the main line 76, so that there is no need to transfer the sub-work bench to a conveyance carriage (such as an unmanned conveyance carriage). Therefore, it is possible to improve the efficiency of logistics and to reduce logistics costs. In this way, since no transfer work is required, one person can work.

  Further, according to the present embodiment, the work carriage 75 is provided with the rib 77 and the rear end portion of the carpet module 1 is raised to insert the other end portion 57 b of the operation lever 57 into the hole portion 22 of the carpet module 1. It is possible to prevent the carpet module 1 from being damaged, and the carpet module 1 can be prevented from being damaged.
