Abstract

PURPOSE:To provide a stacker which stacks worked materials without shifts and also prevents a fall. CONSTITUTION:A stacker for stacking worked materials wherein a table 1 having a passage hole 7 a little smaller than the worked materials and guiding the worked materials sent on the passage hole 7 is provided therein, a stack table is elastically attached under the table 1 so as to stop up the passage hole 7, and a pressing portion 14 for moving it to a stack table 12 is provided movably in the vertical direction while sandwiching the worked materials with the stack table 1, so that the worked materials can be stacked without shifts, and also prevented from falling.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacker in which small pieces of cloth that have been cut or bonded are aligned and stacked.

[0002]

2. Description of the Related Art A conventional stacker is used for a relatively large work piece, and a stacker for a small work piece having a small weight has not been put into practical use. ing. In this conventional stacker for large objects, a work piece that has been cut or bonded is conveyed by a belt and once placed on a slide table, and then the slide table is moved to lower the work piece. It is configured to be dropped onto and stacked on a stack table.

[0003]

When stacking small workpieces, for example, so-called "Tenggu" elongated workpieces, with the above-mentioned large-sized stacker, the following problems occur. That is, (1) since the slide table moves with the work piece placed thereon, when the work piece is lightweight, it does not drop directly below,
The stacked workpieces are misaligned and become uneven. (2) Since the width is narrow, the stack will fall if the stack height becomes large.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a stacker in which workpieces can be stacked without displacement and can be prevented from falling.

[0005]

A stacker of the present invention is for stacking workpieces 6 and has a through hole 7 which is slightly smaller than the workpiece 6 and allows the workpiece 6 conveyed to pass therethrough. 7. A guiding table 1 is provided on the table 7, and a stack table 12 is elastically pressure-contacted to a lower portion of the table 1 so as to close the passage hole 7, and a workpiece 6 is sandwiched between the stack table 12 and the upper portion of the table 1. The present invention is characterized in that the pressing portion 14 for moving the stack table 12 while being vertically movable is provided.

[0006]

In the stacker of the present invention, the workpiece 6 is placed on the table 1.
The work piece 6 is guided to above the through hole 7 of the pressing portion 1
4 and the stack table 12 move between the stack table 12 and the stack table 12 and elastically press-contact between the table 1 and the stack table 12, so that the workpieces 6 are stacked in a fixed position without displacement. Moreover, the fall can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The table 1 is fixed to the central portions of the side frames 2a, 2a of a rectangular frame 2, and the conduction mechanism 3 is attached to the lower end portion. This conduction mechanism 3 is connected to the upper ends of the two columns 5 of the base 4, whereby
The levelness of the table 1 with respect to the base 1 can be changed.

The table 1 is formed with a passage hole 7 which is slightly smaller than the workpiece 6 conveyed from a processing machine (not shown). Further, a pipe 8 is attached to the end portion on the processing machine side, and a passage hole 7 is formed from a plurality of holes formed in the pipe 8.
The compressed air is blown out toward. Further, between the pipe 8 and the passage hole 7, a pair of guide plates 9 for guiding the workpiece 6 onto the passage hole 7 is provided.
The support plate 10 is attached to the lower frame 2b of the frame 2,
A plurality of guide bars 11 are laid between the support plate 10 and the table 1. Stack table 12
Is fitted to a plurality of guide bars 11, and is pressed by a plunger 13 that operates at, for example, 2 atmospheres so as to be vertically movable to the lower surface portion of the table 1 so as to close the passage hole 7.

The pressing portion 14 is mounted on the upper frame 2c of the frame 2 and operates at 4 atmospheric pressure, and a support plate 16 mounted on the plunger 15 so as to be vertically movable.
And a pressing plate 17 having a U-shaped cross section attached to the lower end of the support plate 16. This pressing plate 17
Has a shape corresponding to the passage hole 7 and is formed slightly smaller than the passage hole 7. Moreover, the cross-sectional shape is configured so that when the workpiece 6 is pushed into the passage hole 7, no abnormal deformation occurs in the workpiece 6.

Next, the operation of this embodiment will be described. (1) The transmission mechanism 3 is driven so that the end portion of the table 1 is aligned with the workpiece discharge portion of the processing machine (not shown). The workpiece 6 supplied from the processing machine is the inclination of the table 1 and the pipe 8
Sent to the compressed air blown out from the pair of guide plates 9
And is guided to above the passage hole 7 (see FIG. 3). (2) Next, the plunger 15 of the pressing portion 14 is actuated, the pressing plate 17 descends, enters the passage hole 7 while deforming the workpiece 6, and the workpiece 6 is transferred to the stack table 12 And the workpieces 6 stacked on it. As a result, the workpiece 6 is sandwiched between the pressing portion 14 and the stack table 12 at a fixed position immediately below the passage hole 7 (see FIG. 4).

(3) The pressing portion 14 continues to descend while displacing the stack table 12 downward while holding the work piece 6 sandwiched between the work piece 6 and the work piece 6 from the table 1 to the stack table 12. Move (see FIG. 6). (4) Then, when the pressing portion 14 retracts, the stack table 12 rises while holding the workpieces 6 sandwiched therebetween, and the stacked workpieces 6 are pressed against the table 1 (see FIG. 6). (5) The process returns to the step (1) again, and the steps (1) to (4) are repeated.

The present invention is not limited to the embodiment described above and shown in the drawings. For example, the stack table 12 may be elastically pressed against the lower surface of the table 1 by a spring. Various modifications are possible without departing from the gist.

[0013]

The stacker of the present invention has the following excellent effects. (1) The pressing unit 14 moves the workpiece 6 from the table 1 to a position directly below the passage hole 7 on the stack table 12 while sandwiching the workpiece 6 in cooperation with the stack table 12. No deviation occurs in the workpiece 6. (2) The stacked workpieces 6 are always pressed against the table 1 by the stack table 12, so that the stacked workpieces 6 can be prevented from falling.
