Suction device for grasping and handling a generally parallelepipedic body

Claim 2

A suction device for grasping and handling a generally parallelepipedic body comprising: a. means forming a first suction head member having a first suction face adapted for releasable suctorial adhesion to a first surface of the body that is originally the top thereof, b. means forming a second suction head member having a second suction face adapted for releasable suctorial adhesion to a second surface of the body that is originally a laterally facing side thereof, c. carrier means common to said first and second suction head members, d. means for oscillating said first and second suction head members jointly relative to said carrier means at least approximately 90° about a generally horizontal axis that is at least substantially parallel to both said first and second suction faces, and e. means for temporarily creating a negative pressure in said first and second suction head members, said suction device leaving two adjoining surfaces of the body opposite to the first and second surfaces thereof, respectively, entirely free so as to permit turning over of the grasped body and depositing of the same on that free side thereof which was formerly facing laterally and away from the second body surface.

Claim 3

A suction device according to claim 1 wherein said first and second suction head members are separate and adjustable relative to each other.

Claim 4

A suction device according to claim 1 wherein at least one of said first and second suction head members is adjustable relative to the other one by turning about an axis that is parallel to said common axis of joint oscillation of the two suction head members.

Claim 5

A suction device according to claim 1 wherein at least one of said first and second suction head members is adjustable relative to the other one by turning about said common axis of joint oscillation of the two suction head members.

Claim 6

A suction device according to claim 1 wherein at least one of said first and second suction head members is adjustable towards and away from said common axis of joint oscillation of the two suction head members.

Claim 7

A suction device according to claim 1 wherein said first and second suction head members are rigidly interconnected to oscillate as a unit relative to said carrier means, and wherein said first and second suction faces form an angle of at least approximately 90° between them.

Claim 8

A suction device for grasping and handling a generally parallelepipedic body comprising: a. means forming a first suction head member having a first suction face adapted for releasable suctorial adhesion to a first surface fo the body that is originally the top thereof, b. means forming a second suction head member having a second suction face adapted for releasable suctorial adhesion to a second surface of the body that is originally a laterally facing side thereof, c. carrier means common to said first and second suction head members, d. a first yoke member supporting said first suction head member, e. a second yoke member supporting said second suction head member, f. means for oscillating said first and second yoke members and, hence, said first and second suction head members individually as well as jointly relative to said carrier means about a common, generally horizontal axis that is at least substantially parallel to both said first and second suction faces and located at a distance from and in front of both of them, and g. means for temporarily maintaining a negative pressure in each of said first and second suction head members in order to cause their suction faces to adhere to the body separately or jointly, as required.

Claim 9

A suction device for grasping and handling a generally parallelepipedic body comprising: a. means forming a first suction head member having a first suction face adapted for releasable suctorial adhesion to a first surface fo the body that is originally the top thereof, b. means forming a second suction head member having a second suction face adapted for releasable suctorial adhesion to a second surface of the body that is originally a laterally facing side thereof, c. carrier means common to said first and second suction head members, d. a first yoke member supporting said first suction head member, e. a second yoke member supporting said second suction head member, f. means for oscillating said first and second yoke members and, hence, said first and second suction head members individually as well as jointly relative to said carrier means about a common, generally horizontal axis that is at least substantially parallel to both said first and second suction faces and located at a distance from and in front of both of them, and g. means for temporarily maintaining a negative pressure in each of said first and second suction head members in order to cause their suction faces to adhere to the body separately or jointly, as required.

Claim 10

A suction device according to claim 7 wherein at least one of said first and second suction head members is attached to its related yoke member by means permitting adjustment of the head member towards and away from said common axis of oscillation of the two yoke members.

Claim 11

A suction device according to claim 7 wherein each of said first and second suction head members is attached to its related yoke member by adjustment means permitting convenient variation and setting of the distance between said common axis of oscillation of the two yoke members and the suction face of the head.
