It is a device that can reciprocate the load 200 in the transfer direction via the contact member 102 that engages with the H.291. In the case of the present embodiment, the transfer drive device 104 reciprocates the engagement member 121 and the contact member 102 in the transfer direction, and accordingly, the rotation drive device 103 also reciprocates. Specifically, for example, the transfer drive device 104 includes an engagement member 121, a contact member 102, a rail that guides the rotation drive device 103 in the transfer direction, and a linear motion unit that reciprocates these.

  Next, the operation of the transfer device 100 when transferring the luggage 200 in the first holding unit 300 to the second holding unit 101 will be described.

  FIG. 6 is a diagram showing the operation of the transfer apparatus in stages.

  As shown in the upper part of the figure, the engaging member 121 and the abutting member 102 are arranged by the rotational drive device 103 at the immersion position that is the lower position of the luggage 200 that does not interfere with the luggage 200. In this state, the engaging member 121 and the abutting member 102 can be passed below the luggage 200.

  Next, as shown in the middle part of the figure, the rotation drive device 103 rotates the engagement member 121 and rotates the contact member 102 that is interlocked with the engagement member 121. The stop means 106 stops the rotation of the contact member 102 in a protruding state in which the horizontal portion 120 of the contact member 102 is horizontal. In this state, the contact member 102 is in a state where it can contact the first surface portion 291 of the luggage 200.

  Next, the transfer driving device 104 slides the contact member 102 together with the engagement member 121 in the transfer direction so that the contact member 102 contacts the first surface portion 291 of the luggage 200 held by the first holding unit 300. Make contact. At this time, the transfer driving device 104 considers the displacement of the load 200 held by the first holding unit 300, and even if the assumed maximum displacement occurs in the load 200, the contact member 102 remains in the first surface portion. The amount of movement of the abutting member 102 so as to abut on 291 is set. As a result, the contact member 102 reliably contacts the first surface portion 291. In addition, when the luggage 200 is not significantly displaced, the contact member 102 contacts the first surface portion 291 at an early stage, but the biasing member 107 absorbs the impact and drives the transfer driving device 104 after the contact. The urging member 107 absorbs.

  Thus, the positioning of the engaging member 121 and the engaged portion 201 of the luggage 200 can be reliably performed.

  Further, the rotation drive device 103 rotates the engagement member 121 in the protruding direction. In this state, since the abutting member 102 exists between the engaging member 121 and the first surface portion 291, the engaging member 121 does not rub against the first surface portion 291, and dust generation and the first surface are not performed. Damage to the portion 291 can be prevented.

  Next, when the engaging member 121 is rotated in the protruding direction, the inclined portion 171 of the engaging member 121 contacts the jaw portion 211, and the inclined portion 171 gradually pushes up the jaw portion 211.

  Thus, the first surface portion 291 side of the luggage 200 is gradually lifted. Moreover, since the two engaging members 121 rub against the jaw 211 while rotating in the opposite directions, the first surface portion 291 side can be lifted without much shifting in the width direction.

  Next, as the rotation drive device 103 further rotates the engagement member 121 and the engagement member 121, the push-up portion 141 and the jaw portion 211 come into contact with each other as shown in the lower part of the figure.

  In this state, the first surface portion 291 side of the luggage 200 is lifted to a position higher than the stopper 301.

  In addition, the two pressing portions 151 press the respective wall portions 221 outward in the width direction of the luggage 200. As a result, the load 200 is centered, and the shift in the width direction is eliminated.

  In addition, since the restricted portion 161 is in contact with or substantially in contact with the restricting portion 231, the first surface portion 291 side of the luggage 200 does not rise any further, and the upper and lower sides when the luggage 200 is transferred Shaking of the direction can be suppressed.

  Further, since the engagement member 121 and the engagement member 121 hold the first surface portion 291 side of the luggage 200 in a fixed state, the luggage 200 can be prevented from falling off from the engagement member 121 and the engagement member 121.

  In the above state, the transfer driving device 104 moves the engagement member 121 and the contact member 102 in the transfer direction (Y-axis direction in the drawing), so that the engagement member 121 moves to the engaged portion 201. It is possible to engage and move the load 200 in the transfer direction while sliding.

  As described above, since the first surface portion 291 side of the luggage 200 is higher than the stopper 301, the movement of the luggage 200 is not prevented by the stopper 301. Further, since the entire load 200 is inclined, the contact area between the first holding unit 300 and the load 200 is reduced, and the frictional resistance when the load 200 is transferred can be reduced.

  Next, after the movement of the luggage 200 is completed, the engagement member 121 and the contact member are rotated to the immersion position shown in the upper part of FIG. The two holding portions 101 can be lowered, and an unintentional impact on the luggage 200 can be avoided.

  In addition, this invention is not limited to the said embodiment. For example, another embodiment realized by arbitrarily combining the components described in this specification and excluding some of the components may be used as an embodiment of the present invention. In addition, the present invention includes modifications obtained by making various modifications conceivable by those skilled in the art without departing from the gist of the present invention, that is, the meaning described in the claims. It is.

  For example, although two contact members 102 that simultaneously contact the first surface portion 291 are illustrated, one contact member 102 may be used.

  Further, in the transfer direction, the contact members 102 may be disposed on both sides of one engagement member 121 so that the two engagement members 102 sandwich the one engagement member 121. Thereby, even when there are holding portions on both sides of the transfer device 100, the load 200 can be transferred to the holding portion on either side by using one engagement member 121, and the operation of the contact member 102. The effect can be demonstrated.

  Further, the luggage 200 can be applied to the luggage 200 in any holding state, such as being held in a suspended state as well as being held.

  Moreover, although the luggage | load 200 provided with the engaging member 121, the jaw part 211, etc. in the 1st surface part 291 was illustrated, the luggage | load 200 is a surface different from the 1st surface part 291 of the surface which cross | intersects a transfer direction. The surface portion may also include the engaging member 121, the jaw portion 211, and the like.

  The present invention can be applied to a transfer device that transfers packages at an automatic warehouse, a distribution base station, or the like.
