Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In the present invention, a poly case, which is a storage container for physical items used during physical distribution, is loaded on the transportation pallet (hereinafter referred to as palletizing) or is unloaded from the transportation pallet (hereinafter referred to as depalletizing). The present invention relates to a transportation device for a physical distribution item storage case.

[0002]

[Prior art]

 In the conventional palletizing or depalletizing, for example, a rectangular poly case W stacked on the transfer pallet 3 as shown in FIG. 8 is installed from the top to the tips of the clampers 13a, 13b as shown in FIG. It is held by the claw members 14a and 14b, and is carried to a predetermined place by a carrying device (not shown).

A clamper drive unit 13 is provided in the hand unit 12 of the known XY direction moving device 1 shown in FIG. 7, and the clamper drive unit 13 drives the clampers 13 a and 13 b to open and close. Claw members 14a and 14b are fixed to the tips of the clampers 13a and 13b at right angles to the clampers 13a and 13b. Next, a large number of rectangular poly cases W stacked on the pallet 3 shown in FIG. 8 are claw members 14a of clampers 13a and 13b provided on the hand portion 12 of the XY movement device 1 shown in FIG. , 14b to clamp the poly case W, the hand portion 12 is moved in the X and Y directions by the XY direction moving device 1 to move the claw members 14a, 14b of the clampers 13a, 13b into the rectangular poly case. W is moved upward, the clamper 13a Ri by the clamper driving unit 13, the claw member 14a of 13b, by opening and closing the 14b, the flange portion W _a of the clamper 13a below the poly case W, 13b of pawl member 14a, 14b While holding the rectangular poly case W, the rectangular poly case W is gripped and moved in the X and Y directions by the XY moving device 1 or in the Z direction which is the up and down direction to the desired place. It has been sent.

[0004]

[Problems to be solved by the device]

 However, in the method shown in FIG. 7, the rectangular poly case W must be gripped from above by the claw members 14a, 14b of the clampers 13a, 13b, so that the claw members 14a, 14b are opened and closed as shown in FIG. However, it is necessary to load the rectangular poly case W on the transport pallet 3 with a gap B that does not hit the adjacent rectangular poly case W. Therefore, the number of rectangular poly cases W loaded on the same-sized transfer pallet 3 is reduced accordingly, and there is a problem that the transfer work efficiency is reduced. When stacked, the stability deteriorated due to the gap B, and there was an accident in which the rectangular plastic case W collapsed and dropped from the transport pallet 3.

[0005]

[Means for Solving the Problems]

 The present invention has been made in order to solve the problems in the prior art. Claim 1 is a first gripping portion which is loosely fitted to the upper and lower surfaces of a gripped edge formed at the upper part of a distribution product storage case. A second gripping portion that contacts the lower surface of the gripped edge other than the predetermined location, and a second gripping portion that contacts the gripped edge upper surface between the predetermined location of the gripped edge and the gripped edge portion other than the predetermined location. A third gripping portion, a third gripping portion driving device that drives the third gripping portion in the vertical direction, an X-Y direction in which the first gripping portion, the second gripping portion, and the third gripping portion driving device are fixed. A moving part and a driving device for the moving part in the XY direction, wherein the gripped edge formed on the upper part of the distribution product storage case has a lower surface of two parts spaced apart on a horizontal plane. Both the first gripping part and the second gripping part that come into contact with each other and the first gripping part that comes into contact with the upper surface of the edge to be gripped A first gripping portion, a third gripping portion that vertically overlaps the second gripping portion, a third gripping portion driving device that drives the third gripping portion in the vertical direction, and the first gripping portion. It is composed of an XY direction moving part to which the second gripping part and the third gripping part driving device are fixed, and a driving device for the XY direction moving part.

[0006]

[Action]

 According to the above configuration, in claim 1, the first gripping portion is moved to a lower surface of a predetermined portion of the physical distribution article storage case by moving the XY direction moving unit, for example, in the X direction by the driving device of the XY direction moving unit. To play with. Next, in a state where the movement in the X direction is stopped, the XY direction moving unit is moved in the Y direction by the driving unit for the XY direction moving unit to move the second gripping unit to a gripped edge other than the predetermined location. Located on the underside of. Subsequently, the third gripper driving device moves the third gripper downward to grip the gripped edge formed on the upper part of the distribution product storage case together with the first gripper and the second gripper, The distribution device storage case is conveyed to a predetermined position by the driving device of the XY direction moving unit.

Further, according to the second aspect, the first gripping portion is formed on the upper portion of the physical distribution article storage case by moving the XY direction moving portion, for example, in the X direction by the driving device of the XY direction moving portion. It is located on the lower surface of a predetermined place of the gripped edge. Next, while the movement in the X direction is stopped, the XY direction moving unit is moved in the Y direction by the driving unit for the XY direction moving unit to move the second gripping unit to a gripped edge other than the predetermined position. Located on the underside of. Then, the third gripper driving device is driven to move the third gripper downwards to grip the gripped edge formed on the upper portion of the physical distribution product storage case together with the first gripper and the second gripper. Then, the physical distribution product storage case is transported to a predetermined position by the drive device of the XY direction moving unit.
