Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking load delivering device used for transferring stacked loads such as a plurality of stacked plate-like works to a transfer side such as a roller table.

[0002]

2. Description of the Related Art In a conventional delivery device of this type, a substantially U-shaped movable base into which plate-like works stacked in a plurality of stages as stacked loads are loaded in a vertical posture is rotatable in a plane vertical to the device body. The workpiece is pushed out by a pushing mechanism from the bottom side of the movable table while being pivotally supported and rotated about 90 °, and is transferred to, for example, the roller table side.

[0003]

However, according to the conventional structure as described above, when the movable table is rotated, the pushing mechanism is driven to push out the work as it is. In particular, when the work is pushed out to an object having an unstable movement such as a roller table, there is a problem that the work is likely to fall or the load collapses.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a stacked baggage delivery device capable of preventing lateral slippage and load collapse during the transfer of stacked baggage.

[0005]

In order to achieve the above object, the present invention provides a movable base with a pressing plate that elastically presses stacked loads from one side of the stacking direction, and the stacked loads are loaded from the movable base. A cylinder device is provided for displacing the pressing plate in the extruding direction in the pushing operation in synchronization with the pushing operation.

[0006]

According to the above construction, since the pressing plate that presses from one side in the stacking direction of the stacked luggage carried into the movable table is displaced in the pushing direction in synchronization with the pushing mechanism when the movable table is rotated, the stacking is performed. The lateral displacement of the loads is prevented by the pressing plate, and the stacked loads can be stably transferred.

Reference numeral 25 denotes a guide member which is provided on the standing frame portion 9 and guides the holding body 22 of the air cylinder 20.

A roller table 27 having a large number of conveying rollers 26 arranged in a left-to-left direction is provided between the work carry-in section 2 and the work carry-out section 3 via a rotation support mechanism 28 with respect to the apparatus main body 1. Supported. 29 is the apparatus main body 1
A motor attached to the motor for rotating the roller table 27 via the speed reducer 30 is a chain for transmitting the rotation output of the speed reducer 30 to the base 32 of the roller table 27. The motor 29, when the work M is placed on the roller table 27 from the movable table 4,
The roller table 27 is configured to rotate 180 °. A work receiving wall 33 is provided at the left end of the roller table 27. By the roller table 27, the motor 29, etc., the stacked luggage rotating means 100
Are configured.

A pair of movable rails 34, 34 extending to the work unloading section 3 side are disposed on both front and rear sides of the roller table 27.
The left and right hydraulic cylinder units 35 and 35 are vertically movable. Reference numerals 36 and 36 denote carriages that are movably held along the rails 34 and 34 and pick up the work M on the roller table 27 when the rails 34 are displaced upward. By the rails 34, 34 and the hydraulic cylinder devices 35, 35, the carrier platform elevating means 200 is provided.
Is configured.

Reference numeral 37 is a motor attached to the lower left end of the rail 34, and is configured to move the carrier 36 along the rail 34 to the work unloading section 3 via chains 38 and 39. .. Reference numerals 40 to 43 are chain sprocket. By the motor 37, the chains 38, 39, etc., the carrier table elevating means 20.
A stacking load carrying means 300 for carrying out the work M to the work carry-out section 3 by causing the carry table 36 to perform a square-shaped motion with 0.

The work unloading section 3 is composed of a plurality of unloading rollers 44 and a roller mount 45 arranged side by side in the front-rear direction. Next, the operation of the above configuration will be described. First, when a plurality of plate-like works M are loaded into the work unloading section 2 in a vertical posture, the pressing plate 19 presses the works M from one side in the stacking direction by driving the air cylinder 20.
When the cylinder device 10 is driven in this state, the piston rod 12 extends and the movable table 4 in the work carrying-in section 2 rotates counterclockwise about the shaft support member 5 as shown in FIG. At this time, the cylinder device 16 in the pushing mechanism 14 is driven, and the pushing member 15 pushes the entire work M as it is toward the roller table 27 side.

On the other hand, as the movable table 4 rotates, the piston rod 24 of the cylinder device 23 held by the standing frame portion 9 extends in the direction of arrow a in FIG. 4 in a free state. Therefore, the pressing state of the pressing plate 19 against the work M is maintained until the work M is pushed out from the movable table 4. That is, the work M is rotated by the rotation of the movable table 4.
Is displaced as shown by the chain line in FIG. 4, the pressing plate 1
As indicated by arrow F, the work M is displaced while following the pushing of the work M while elastically pressing the work M,
Can be transferred onto the roller table 27 without being laterally displaced.

When the work M is pushed out to the roller table 27 side, the piston rod 12 of the cylinder device 10 is pushed.
Contracts and the movable table 4 rotates clockwise and is restored to the original state. When the work M is placed on the roller table 27 as shown in FIG. 5, the motor 29 is driven to rotate the roller table 27 by 180 ° via the chain 31. Thereafter, the hydraulic cylinder devices 35, 35 drive the transfer table 36 upward together with the rail 34 as shown in FIG. 6, so that the work M on the roller table 27 is picked up by the transfer table 36. In this state, if the motor 37 is driven and the carrier 39 is linearly moved to the left along the rail 34 by the chain 39, the carrier M mounts the work M as shown in FIG. Move to the work unloading section 3.

At this time, 180 ° with respect to the work M
The direction of the work is changed by the roller table 27, and the work M
Is conveyed to the work unloading section 3 side by the roller table 27.
Since the work is carried out by the carrying table 36 which is separate from the above, the work M does not become unstable at the time of carrying, and therefore the collapse of the load is prevented.

When the transfer table 36 on which the work M is placed reaches the work unloading section 3 side, the hydraulic cylinder devices 35, 3 are used.
When the carrier table 36 is lowered together with the rail 34 by 5, the work M on the carrier table 36 is transferred onto the carry-out roller 44 of the work carry-out section 3 as shown in FIG. After that, the carriage 37 is moved to the right along the rail 34 by the motor 37, and is restored to the original state. That is, the workpiece M on the roller table 27 is transported to the workpiece unloading section 3 side by the transfer table 36 performing a square-shaped motion.

At this time, if the roller table 27 is returned to its original position while the work table 36 is carrying the work M to the work carry-out section 3 side, the work M from the work carry-in section 2 side is described above. It can be received by the roller table 27. That is, since the operation of receiving the work M by the roller table 27 can be performed without interfering with the process on the unloading side of the work M, wasteful waiting time for receiving the work is eliminated.

[0020]

As described above, according to the present invention, the pressing plate for pressing the stacked loads carried on the movable table in the stacking direction is provided.
Since the cylinder device is configured to follow the displacement in the pushing direction in synchronization with the operation of pushing out the stacked baggage when the movable table is rotated, the risk of a load shift when the stacked baggage is pushed out is eliminated, and it is reliable and safe. You can transfer large packages.
