Description

[Detailed Description of the Invention] The present invention relates to a pillow-shaped package loading device for loading the pillow-shaped package into a device for the next process such as an ear forming device.

Pillow-shaped packages are generally manufactured by continuously forming bags from a strip of plastic film and filling the bags with articles.

The pillow-shaped package is then discharged from the manufacturing apparatus with both ears disposed at the front and rear in the discharge direction.

Therefore, when feeding the pillow-shaped package to an ear forming device for simultaneously folding and forming the ears, it is necessary to change the direction of transport of the pillow-shaped package at a right angle and then charge the pillow-shaped package.

However, conventional devices that change the direction of transport of the pillow-shaped package and load it into an ear forming device, etc. have problems due to the fact that the pillow-shaped package is lightweight and its shape is not always exactly the same. Even if it is simply extruded with an extrusion plate, it will be repelled by the pillow-shaped package, and the direction of movement after conversion will not be constant.
There was a problem in that it was not possible to reliably perform subsequent molding steps such as ear molding.

In order to solve the above-mentioned problem, the present invention aims to provide a charging device for pillow-shaped packages that can change direction of the pillow-shaped packages in a stable posture and load them into a forming device for the next process.

The configuration of the present invention will be explained below based on the drawings.

FIGS. 1 and 2 show an embodiment of the present invention, in which a pillow-shaped package P filled with products is produced by a packaging device (not shown) and transported by a conveyor 1 in the direction of arrow A in FIG. and is fed to a fixed position within the charging device 2.

At a fixed position in the charging device 2, the pillow-shaped package P is detected by a detection means (not shown) including a photoelectric switch, etc., and the charging device 2 is activated by the detection signal.

The charging device 2 includes an extrusion plate 3 formed in a die section having a horizontal portion 3' and a vertical portion 3'', an opening/closing plate 4 attached to the tip of the extrusion plate 3, and a reciprocating mechanism for the extrusion plate 3. The drive unit 6 includes a drive unit 6 and an opening/closing drive unit 9 for the opening/closing plate 4.

The opening/closing plate 4 is rotatably hung from the tip of the upper portion 3' of the extrusion plate 3 via a shaft 5, and forms a vertical wall facing the vertical portion of the extrusion plate 3.

In the illustrated embodiment, the reciprocating drive unit 6 reciprocates the extrusion plate 3 and the opening/closing plate 4 attached thereto via a piston rod 8 fitted into a fluid pressure cylinder 7. In this embodiment, the opening/closing drive unit 9 includes a hydraulic cylinder 10 provided on the horizontal portion 3' of the extrusion plate 3, a rack 12 attached to a piston rod 11 fitted into the hydraulic cylinder 10, and the opening/closing plate 4. and a pinion 13 attached to the shaft 5 of the rack and pinion 1 controlled by the fluid pressure cylinder 10 and the piston rod 11.
2.13, the opening/closing plate 4 can be rotated between a closed position shown in solid lines in FIG. 2 and an open position shown in phantom lines in FIG.

The opening/closing plate 4 is rotated in the closing direction by the opening/closing drive section 9 prior to the operation of moving the extrusion plate 3 to the forward side, and then the extrusion plate 3 is operated to the forward side by the reciprocating drive section 6 to extrude. The pillow-shaped package P inside the plate 3 is pushed out in the direction of the arrow in FIG.

In the illustrated embodiment, an ear forming device 15 for a pillow-shaped package is provided at the extrusion direction opening of the charging device 2.

This ear forming device 15 includes forming auxiliary devices 16 and 16' vertically arranged at the extrusion position of the charging device 2, corresponding to both ears E and E' of the pillow-shaped package P; After each forming auxiliary device 16, 16', an endless bell (17, 17') stretched over the extrusion direction opening presses both ears E, E' of the pillow-shaped package P and heats it. It is designed to be bent and formed.

In the charging device 2 configured as described above, the pillow-shaped packages P transferred by the conveyor 1 are introduced into the introduction section formed by the extrusion plate 3, which is waiting with the opening/closing plate 4 opened horizontally. be done.

Next, the opening/closing plate 4 provided at the tip of the extrusion plate 3 is rotated in the closing direction by the opening/closing drive unit 9 to hold the pillow package P in the correct posture.

Next, the reciprocating drive unit 6 of the extrusion plate 3 is driven to the forward side, so that the extrusion plate 3 and the opening/closing plate 4 are moved together to the forward side, and the pillow-shaped package P in the extrusion plate 3 is transferred to the conveyor. It is extruded in a direction perpendicular to the transport direction A of No. 1, and the direction is changed to the extrusion direction port.

After the pillow-shaped package P is pushed out to a fixed position, the push-out plate 3 is moved to the return side by the reciprocating unit 6, and the opening/closing plate 4 is opened to the horizontal state shown by the broken line by the opening/closing drive unit 9.

Thereafter, the push-out plate 3 is moved to the return side by the reciprocating section 6 and returned to its original position, waiting for the next pillow-shaped package to collapse.

The present invention has the structure and operation described above, and a pillow-shaped package is introduced into the introduction part formed by the extrusion plate and the open-close plate provided at the tip of the extrusion plate, and the pillow-shaped package is opened and closed before changing direction. Since the pillow-shaped package is configured to be regulated in the correct posture by the plate 4 and then pushed out to a fixed position and then changed direction, it has the effect of easily changing the direction of the pillow-shaped package in a stable posture. This also has the effect of eliminating molding defects in the next process due to poor posture of the pillow-shaped package whose direction has been changed.

Furthermore, in the present invention, the opening/closing plate is opened and closed by the opening/closing drive unit in synchronization with the reciprocating movement of the extrusion plate, so that any trouble caused by providing the opening/closing plate can be completely eliminated.
