Abstract

PROBLEM TO BE SOLVED: To change the loading direction of each stage of a corrugated cardboard case so as to prevent collapse of goods, by proving a vertically moving base to a horizontally moving base, and providing a carriage with a suction pad for sucking the corrugated cardboard case, to the vertically moving base so that it can be slewed at 90 degrees toward a horizontal direction. SOLUTION: A horizontally moving base is moved along rails 17, 18 in a frame 1 by an X shaft cylinder CX and a Y shaft cylinder CY toward the position of a corrugated cardboard case (a) for which box packing is finished, and stopped at a predetermined position. A vertically moving base and a carriage attached to the vertically moving base are stopped by being lifted or lowered up to a predetermined position by a Z shaft cylinder CZ. The corrugated cardboard case (a) is sucked and retained by a suction pad attached to the carriage, and moved and stopped on a pallet 2 arranged in the frame 1, and the carriage is slewed at 90 degrees and stopped by a slewing cylinder. The loading direction of the corrugated cardboard case (a) loaded on the pallet 2 follows the action of a loading device 3 by a signal previously set in a controller.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard case loading device.

[0002]

2. Description of the Related Art Conventionally, a cardboard case is loaded on a horizontal movement base which can be moved by an X-axis cylinder and a Y-axis cylinder along rails in the front-rear X and left-right Y horizontal directions with respect to a frame. An elevating base that is moved up and down by a shaft cylinder is provided, and a suction pad that adsorbs the cardboard case (a) is provided on the elevating base, and the elevating base is moved back and forth X and left and right Y to the cardboard case (a) position. , And in the vertical Z direction, the cardboard case (a) is sucked and held by the suction pad provided on the elevating base, and is moved to, for example, a pallet installed in the frame, When they are loaded in line on a predetermined position on this pallet, and a predetermined number of cardboard cases (a) are loaded on the lowermost part, the upper part of the lowermost part is doubled. Cardboard case (b) is loaded in the same direction as the direction of the lowermost portion, the second step is completed, a three-stage, and are sequentially stacked and fourth stage.

[0003]

When the cardboard case (a) is loaded on the pallet in the frame, the elevating base may project from the frame depending on the moving position of the elevating base. It is dangerous for the workers who work on the outside of this frame to prevent this danger, and the loading direction of the cardboard case (a)
Since the corrugated cardboard case (a) is easy to collapse due to the same direction in each stage, the collapse is prevented by changing the loading direction in each stage.

[0004]

To this end, according to the present invention, the X-axis cylinder CX and the Y-axis cylinder CY are movable along the rails 17 and 18 in the front-rear X and left-right Y horizontal directions with respect to the frame 1. The horizontal moving base 19 is provided with an elevating base 31 which is moved up and down by a Z-axis cylinder CZ in the vertical Z direction. The elevating base 31 is provided with a carriage 41 having an adsorption pad 41 capable of adsorbing the cardboard case (a). The corrugated cardboard case loading device is configured to be horizontally rotatable by 90 degrees around the axis of the Z-axis cylinder CZ by the swiveling cylinder CS.

[0005]

According to the present invention, the X-axis cylinder C is moved toward the cardboard case (a) position where the packaging is completed waiting at the transfer end portion.
The horizontal movement base 19 is moved along the rails 17 and 18 in the frame 1 by the operation of the X and Y axis cylinders CY, and when it is moved to a predetermined position and stopped, by the operation of the Z axis cylinder CZ. The raising / lowering base 31 and the carriage 40 provided on the raising / lowering base 31 are lifted or lowered to a predetermined position and stopped.
The cardboard case (a) is sucked and held by a suction pad 41 provided at 0, moved to and stopped on a pallet installed in the frame 1, and the carriage 40 moves 90 degrees by the operation of the turning cylinder CS. Cardboards that are loaded on a pallet (a), although rotated and stopped
The stacking direction of is controlled as follows. When loading onto this pallet, in the first stage in plan view, the cardboard case (a) is vertically loaded at one diagonal position on one side, and the cardboard case (a) is horizontally placed at the diagonal position on the other side. All the cardboard cases (a) at the intermediate positions other than the central part are laterally stacked, and the central cardboard case (a) is vertically stacked to complete the first stage. Regarding the loading direction of the second stage, the cardboard case (a) loaded in the four corners is loaded in the direction in which the first stage is rotated 90 degrees.
The other cardboard case (a) is loaded in the same direction as the first stage. The third tier is loaded in the same direction as the first tier, the fourth tier is loaded in the same direction as the second tier, and the fifth and subsequent tiers are loaded in alternating directions.

[0006]

The horizontal movement base 19 does not project from the inside of the frame 1 and is safe for an operator working outside the frame 1. When the cardboard case (a) is loaded, the carriage 40 is By turning 90 degrees, the loading direction can be changed depending on each step, which can prevent the cardboard case (a) from collapsing, and this loading device is cheaper than a commercially available robot. is there.

[0007]
