A traveling trolley is arranged so as to be able to reciprocate along the moving direction of the conveyor, and the support arm of the fixed side clamp mechanism is suspended from the part of the base frame located on the lower side in the conveying direction of the conveyor, and the traveling trolley runs on the base frame. Support arms of the movable clamp mechanism are vertically disposed facing the stationary clamp mechanism, and the main frames of each clamp mechanism are rotatable on both support arms about their respective axes along the conveyance direction of the conveyor. A clamp support frame is supported on each main frame so as to be rotatable around an axis perpendicular to the conveyance direction of the conveyor in plan view, and a pair of clamp tools are connected to this clamp support frame along the swing axis. It is characterized in that it is constructed of a clamp plate which is supported so as to be movable apart and which moves the clamp tool in parallel, and a clamp claw pivotally supported at the tip of the clamp plate.

) will move together with the rear end.

When the sink detection switch detects that the sink (W) has reached the working position, the conveyor (2) and the trolley (5) will stop at the same time, so the rear end of the sink (W) and the movable clamp The relative positional relationship of the tool support arms (8) remains maintained. At this time, the distance between the reference blocks (21) of the clamp mechanism (C) is
) is adjusted according to the depth dimension of the clamp tool (
12) They face each other with a dimension slightly larger than the depth dimension of the sink (W).

When the sink (W) stops, the operator
Cover the top surface with corrugated paper, which is packaging material, and operate the work platform lifting means (30) to move the sink (W) toward the clamp mechanism (C), so that the top surface of the sink (W) is placed at both its front and rear ends. The sink (W) is raised until it touches the lower surface of the clamp tool support frame (11) at a certain point. With the upper surface of the sink (W) in contact with the lower surface of the clamp tool support frame (11), operate the clamp tool actuating cylinder (22) and the clamp claw actuating cylinder (28) to remove the clamp plate (
26) presses the corrugated paper against the side surface of the sink (W), and uses the clamp claw (27) to fold the bottom end of the corrugated paper toward the sink (W) to remove the sink (W) wrapped in the corrugated paper. It is held by the clamp tool (12) and the work platform lifting means (30) is operated to lower.

The sink (W) wrapped in corrugated paper is held between the clamps (12) and the main frame (10)
180 degrees to invert the sink (W) wrapped in corrugated pole paper, and then the work platform elevating means (30) is raised again to move the sink (W) in the inverted position onto the work platform. Stop the receiver with the clamp tool actuating cylinder (
22) and the clamp claw actuating cylinder (28) to move the clamp tool (12) to the clamp release side, and move the clamp support frame (11) to the main frame (
10), the clamp plate (2
6) and the clamp claws (27) are retracted in both directions in the transport direction.

After this, the workbench is lowered, and the sink (W) is transported to the next process by the transport conveyor (2), and after inserting the cushioning material, it is hung with a string. Meanwhile, the cart (5) moves on the base frame (4) and returns to the standby position.

(Effects) In the present invention, a base frame is arranged to cover the upper side of a conveyor conveying a sink, and a traveling cart is arranged on the upper surface of this base frame so as to be movable back and forth along the moving direction of the conveyor.
The support arm of the fixed side clamp mechanism is vertically disposed from the part of the base frame located on the lower side in the conveyance direction of the conveyor, and the movable side clamp is placed facing the fixed side clamp mechanism from the traveling carriage running on the base frame. The support arm of the mechanism is installed vertically,
The main frame of each clamp mechanism is supported on both support arms so as to be rotatable around an axis along the conveyance direction of the conveyor, and the clamp support frame is attached to each main frame on an axis perpendicular to the conveyance direction of the conveyor in plan view. A pair of clamp tools are supported on this clamp support frame so as to be movable toward and away from each other along the pivot axis, and a clamp plate that moves this clamp tool in parallel and a pair of clamp tools are attached to the tip of this clamp plate. Since it is composed of a swingably supported clamp claw, it is possible to handle sinks of different sizes by moving the trolley and moving the clamp tool. The frame is rotatably supported by the main frame, and the main frame is rotatably supported by support arms suspended from the cart and base frame, so the sink after packaging can be turned upside down and sent to the next process. be able to.

This not only makes it possible to automate the packaging of sinks, but also makes it easier to attach the cushioning material and hang strings in the next process.
