Description

DETAILED DESCRIPTION OF THE INVENTION The invention of the present application provides for loading and unloading various cargoes into and out of ship holds, cargo sheds, containers, transport trucks, etc., while leaving them in units at the end of a lift truck. The present invention relates to a load push-pull to be mounted, and more particularly to a gripper structure provided on the front surface of the load push-pull.

Normally, in a lift truck with a load/push-pull, in order to place a load on a slip sheet onto a platen, the tip of the platen pushes up the end plate of the slip sheet, and while the face plate is advanced, the gripper section It is designed to grip the edge of the slip sheet and pull the face plate toward it, but since there is a large gap between the lower jaw member, which is a component of the gripper structure, and the platen, the edge of the slip sheet is gripped at the tip of the platen. Even when the plate is scooped up, the end plate does not rest on the lower jaw member, the lower jaw member and the gripper do not grip the slip sheet, and even when the face plate is pulled toward the vehicle body, the slip sheet remains on the platen. This frequently occurred.

The invention of the present application was completed through intensive research in order to eliminate the above-mentioned drawbacks, and its gist is that the face plate 8 is attached to the upper part of the platen 7 via the pantograph mechanism 5 so as to be freely extendable and retractable. In the lift truck with a load push-pull, a distal claw portion 9a protrudes from the lower end of the face plate 8, the distal claw portion 9a is pivotally connected to the lower jaw member 9 and brought into contact with the platen 7, and the lower jaw member 9 is brought into contact with the platen 7. A face gripper 10 is installed directly above the gripper 9 so as to be vertically movable, and the end face of the underlay sheet of the cargo is scooped up with the tip of the platen 7 and guided onto the lower jaw member 9 through the tip claw part 9a. This is a gripper structure for load/push-pull, which is formed so as to be pressed and gripped from above.

Hereinafter, the present invention will be explained in detail based on Examples.

The lift truck A with a load push-pull consists of a lift truck 1 and a load push-pull 2, and the load push-pull 2 is attached to the tip of the lift truck 1.

The load push pull 2 consists of a face plate part 3, a base part 4 equipped with a second gripper 13, and a pantograph mechanism 5. A plate part 3 is attached and a platen 7 is disposed below the load/push-pull part 2.

The face plate portion 3 consists of a lower jaw member 9 that projects from the lower back of the face plate 8 to the front of the plate 8, and a face gripper 10 that presses against the upper surface of the lower jaw member 9.
The gripper 10 is suspended downward from a press cylinder 11 and is formed to move vertically, and the tip claw portion 9a of the lower jaw member 9 is pivotally attached to the base plate 9b, and the tip claw portion 9a is attached to the platen by its own weight. 7 is in contact with the top.

On the other hand, at the base 4 of the load push pull 2,
A second gripper 13 is vertically suspended by a hydraulic cylinder 12, and a gripping plate 14 is fixed to the tip of the second gripper 13. , even with this hydraulic cylinder 13,
Face plate portion 3 integrally connected to base portion 4
are formed to move up and down at the same time.

Therefore, when moving the cargo 16 loaded on the seat 15, first operate the pantograph mechanism 5 to extend the face plate 3 forward, and scoop up the end of the seat 15 with the tip of the platen 7 and move it to the second position. The sheet 15 is placed on the lower jaw member 9 as shown in the figure.
Advance the lift truck Y so that the end of the Scoop up the sheet 15 and remove the lower jaw member 9
The above guiding process was previously very difficult, and even if the tip of the sheet was scooped up with the tip of the switch 7, the tip of the lower jaw member was located far above the surface of the platen, so the tip of the sheet did not touch the lower jaw. However, in the present invention, the tip claw portion 9a of the lower jaw member 9 is always in contact with the platen 7 as described above. Therefore, the sheet 15 scooped up by the tip of the platen 7 is automatically pushed up onto the tip claw portion 9a and placed on the lower jaw member 9.

After placing the sheet 15 on the lower jaw member 9, the hydraulic cylinder 11 is lowered and the end of the sheet 15 is firmly gripped by the grip plate 10a at the end of the face gripper 10, and the pantograph mechanism 5
While the sheet 15 is pulled back onto the platen 7, the cargo 16 is also pulled onto the platen 7 at the same time. The pantograph mechanism 5 is moved back as far as possible and the hydraulic cylinder 1 is moved as shown in FIGS.
The face gripper 1 is raising the face plate portion 3 and the second gripper 13 while gripping the sheet 15 while operating the grippers 1 and 12.
0, the end of the sheet 15 is removed from the face gripper 10 and dropped onto the platen 7, and then the hydraulic cylinder 12 is lowered and the end of the sheet 15 is secured with the grip plate 14 of the second gripper 13. to grasp. When unloading the cargo 16 at a predetermined location, the platen 7 is lowered and the pantograph mechanism 5
is extended and the load 16 is pushed out with the face plate 8, leaving the sheet 15 as it is on the platen 7.

As described above, according to the present invention, the tip claw portion 9a of the lower jaw member 9 that protrudes from the lower end of the face plate 8 is provided so that the end surface of the sheet can be gripped reliably.
The face gripper 10 is pivoted so that it can be rotated downward by its own weight and brought into contact with the platen 7, and the end surface of the sheet scooped up by the tip of the platen 7 is guided directly onto the lower jaw member 9, and the face gripper 10 is attached from above.
Since the sheet is formed to be pressed by the mandibular member 9, the sheet is reliably guided onto the mandibular member 9, and the end of the sheet placed on the platen is moved onto the mandibular member by moving the platen 7 back and forth or up and down many times. It has become possible to transport cargo much more efficiently without having to go through the trouble of moving it to another location.
