Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a laminated sheet stacking device for stacking a predetermined number of sheet blocks such as stacked paper or carton blanks at a predetermined position. It is something.

[Prior art and its problems]

To align and stack sheet-like blocks such as paper or carton blanks stacked in predetermined amounts on a pallet or the like, the blocks 1 are placed on a transfer table 2, as shown in FIG. 6, for example, and moved to a predetermined position. Then, as shown in FIG. 7, the stopper 3 was pressed against the rear of the blocks, the transfer table 2 was retreated to its original position, and the blocks were accumulated and arranged.

However, when the blocks are stacked and aligned using the above method, as shown in FIG. Accumulation was difficult.

[Problem to be solved]

When arranging and stacking sheets of paper or carton blanks stacked in predetermined amounts on a pallet, etc., the blocks can be stacked and aligned in a uniform state without the front and rear ends being slanted. An object of the present invention is to provide an accumulation device for laminated sheet materials.

[Means for solving problems]

A front stopper is provided with a transfer table that reciprocates horizontally over a certain distance in response to a signal from a limit switch on which a predetermined amount of laminated sheet blocks is placed, and a transfer table is provided at the stop position of the transfer table. A support arm is provided that rotates upward by 90 degrees toward the transfer table using the lower end of the front stopper as a fulcrum in response to a signal from a limit switch accompanying the movement of the block, and a rear stopper that moves up and down at a position behind the laminated sheet block in response to the same signal. It was resolved by this.

[Effect]

When the transfer table carrying the laminated sheet block stops at the front position, the support arm rotates 90 degrees and supports the front end of the laminated sheet block.
In addition, the transfer table is moved back with the rear stopper being lowered. Then, when the transfer table retreats from the rear stopper, the support arm returns to its original position and the laminated sheet blocks fall, allowing them to fall in the stacked state.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing an automatic stacking device having a stacking device for laminated sheet materials according to the present invention, in which carton blanks are punched into a predetermined shape from a delivery section of a punching machine, and unnecessary portions have been removed. It flows in a sashimi-like manner with the ends of a certain length overlapping each other.
The carton blanks are transferred to a stacking and aligning device through a transport section 10, a primary stacking section 20 that stacks a predetermined number of carton blanks on the transport section 10, and a secondary stacking section 40 in which the carton blank blocks stacked in the primary stacking section 20 are transferred to a secondary stacking section 40. Transfer unit 30, transfer unit 3
This is an automatic stacking device for sheet-like materials, which comprises a secondary stacking section 40 for stacking carton blank blocks transferred from 0 on a pallet in a predetermined number of stages and rows, and a discharge section 50 for discharging the pallet on which the carton blank blocks are placed. , the present invention provides the secondary accumulation section 4
This is a stacking device for laminated sheet materials that stacks carton blank blocks at 0.

As shown in FIG. 2, this stacking device includes a transfer table 41 on which a predetermined number of rows of stacked carton blank blocks are placed, and which is moved back and forth a certain distance by a limit switch, and a transfer table 41 is installed at a forward stop position of the transfer table 41. A support arm 43 that rotates toward the transfer table with the lower end of the front stopper 42 as a fulcrum in response to a limit switch signal as the transfer table 41 moves below the front stopper 42, and a carton blank supported by the same signal. This is a laminated sheet accumulating device consisting of a rear stopper 44 that descends at a position behind block A.

In the above explanation, the carton blank blocks are stacked one row at a time. However, when the carton blank blocks are stacked two rows at a time, as shown in FIG. A first rear stopper 46 having a support arm 45 having the same configuration as the support arm 43 that rotates toward the transfer table side in response to a limit switch signal accompanying the movement of the rear stopper 46 and a second rear stopper 47 having the same configuration as the aforementioned rear stopper 44 are provided. This is an accumulation device for laminated sheet materials.

Next, the operation of this integrated device will be explained.

A predetermined amount of carton blank blocks A are placed with their tips protruding from the front end of the transfer table 41, and in this state the transfer table 41 is moved toward the front stopper 42. A signal from the limit switch accompanying this movement causes the support arm 43 to rotate upward by 90 degrees and support the tip of the carton blank block A, while the rear stopper 44 descends and presses the rear of the carton blank block A. In this state, the transfer table 41 is moved backward, and when it reaches the position of the front end rear stopper 44, the support arm 43 is returned to its original position, and the carton blank blocks A are dropped and stacked on the pallet B.

This pallet B is placed on a lifter and can be moved up and down, so that the pallets are stacked at the same height.

Next, in the device shown in FIG. 3, when stacking the first row, the front stopper 42 and the support arm 43 are
Although it is the same as FIG. 2, the first rear stopper 46 and the second rear stopper 47 with the support arm 45 rotated upward are located at the upper end, and the transfer table 4
1 advances to the position of the front stopper 42,
The support arm 43 rotates upward to support the tip of the carton blank block A, and the first rear stopper 46 descends. In this state, the two support arms 43 and 45 whose front end of the transfer table passes through the position of the first rear stopper 46 return to their original positions. And another carton blank block
When the transfer table on which A' is placed moves forward to the position of the first rear stopper 46, the support arm 45 rotates upward and similarly supports the tip of the carton blank block A, and when the transfer table 41 moves back, the support arm 45 rotates upward to the position of the first rear stopper 46. It is accumulated in the same way as explained in .

〔effect〕

Since the stacking device of the present invention has the above-mentioned configuration, it is possible to
They can be stacked in their original stacked state without bending.

In addition, the amount of movement of the transfer table that moves back and forth is
The rotation of the support arm and the vertical movement of the rear stopper are regulated by a limit switch, and the rotation of the support arm and the vertical movement of the rear stopper are synchronized by the signal from the limit switch accompanying the movement of the transfer table, allowing accurate stacking with a simple mechanism.

Furthermore, even when changing the number of rows to be accumulated, this can be done by changing the limit switch that is activated.
