Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for overturning and discharging corrugated cardboard, etc., and in particular, a device for overturning corrugated cardboard, etc. that saves space and shortens the time required to supply sheets to the paper feed section. Regarding a sending device.

Conventional technology Conventionally, in the production of corrugated boxes, etc., stacked corrugated cardboard is carried into an overturning delivery device, and the overturning delivery device is overturned to sequentially fold the stacked cardboard in small batches or into a state like a tiled roof. This is done by feeding the corrugated paper to the cardboard feeder using a conveyor.

The dimensions of the cardboard boxes vary widely, and the stacking height of the cardboard boxes carried into the overturning and discharging device can be up to 200mm.
It varies over 0s. Therefore, in the past, the sheet support part of the overturning and discharging device that supports the stacked corrugated paperboards was set at the maximum height of the stacked corrugated paperboards, and the overturning and dispensing device equipped with the stacked corrugated paper was overturned to form sheets. The overturning and discharging device was erected after all of the corrugated paperboard loaded on the support section had passed through the sheet support section.

Problems to be Solved by the Invention In recent years, improvements in the productivity of cardboard boxes in particular have led to higher processing speeds, and the conveyance speed of conveyors has gradually become faster.

However, as mentioned above, the overturning and discharging device is designed to raise and lower the sheet support section at the maximum height corresponding to the stacked height of the corrugated cardboard, so all the loaded corrugated cardboard must pass through. When corrugated boxes and the like are produced at high speed, the overturning delivery device becomes a bottleneck in cycle time.

One possible solution to this problem would be to lengthen the conveyor line leading to the paper feed section and increase the amount of corrugated paper stored, but this requires a large space and cannot be adopted in the current production line where space saving is required. It was impossible.

Means for Solving the Problems The present invention was made in view of the above-mentioned problems, and in order to solve the above-mentioned problems, sheets of corrugated paper or the like stacked on an overturning sending device are sequentially stacked by overturning the overturning sending device. In an overturning device for feeding sheets of corrugated paper, etc.,
An extension sheet support part is extendably disposed on the seat support part of the overturning and sending device, and the extension seat support part is extended from the seat support part in accordance with the amount of stacked sheets to freely support the sheet. Corrugated paper, etc., characterized in that the overturning and sending device is turned over and stacked sheets are fed sideways, and at least when the sheets have passed through the sheet support portion, the extended sheet support portion is contracted to form the overturning and sending device so as to be freely erectable. To provide overturning delivery device.

According to the present invention, the extended sheet supporting section is extendably disposed on the sheet supporting section of the overturning and discharging device, and the stacked sheets are loaded by extending the extended sheet supporting section in accordance with the amount of sheets to be stacked. I can support it. Then, when the overturning sending device is overturned and the loaded sheet is sent out, and all the sheets have passed through the seat support section and the extension support sheet is retracted, there is no longer a sheet in the seat supporting section, so the overturning sending device The machine can stand up and load the next stack of sheets, shortening the sheet feeding cycle time and increasing production capacity.

Example Hereinafter, the present invention will be explained based on examples.

FIG. 1 and subsequent figures show an embodiment of the present invention. The overturning and sending device 3 that overturns the stacked corrugated paper sheets 1 and sends them to the paper feed section 2 is equipped with a sheet loading section 5 and a sheet supporting section 6, which are installed in the main body 4 of the device, like a forklift, as shown in Fig. 1. A tipping delivery section 7 formed in a shape is arranged so as to be able to tip over on the rear side using a tipping drive device (not shown) such as an air cylinder. As shown in FIGS. 1 and 2, an extension seat support section 8 is telescopically attached to the seat support section 6 using a rack and pinion drive or a chain suspension drive device (not shown). The extension sheet support section 8 can be extended in accordance with the stacked height of the sheets 1 fed from the extension sheet support section 8 or by a sheet height detection sensor 8a installed separately.

The overturning delivery device 3 formed in this way is caused to overturn as shown in FIG. 2 by actuating the overturning drive device by the sheet delivery detection sensor 12 disposed on the delivery conveyor 10.11 side of the upper part of the device main body 4. , the stacker 13 is raised to send out the stacked sheets 1 rearward in the same way as the conventional overturning and sending device.

The sheet feed detection sensor 12 is connected to the extended sheet support section 8 by a rack and pinion drive or chain suspension drive device 14.
It is possible to move in synchronization with the amount of expansion of. As this tuning means, for example, electrical tuning means such as a sershin tuning device, or mechanical tuning means such as a link mechanism of a chain or a wire lobe, etc., can be appropriately arranged.

Then, the sheet feeding detection sensor 12, which has moved corresponding to the height of the next stacked sheet 1, detects the previous stacked sheet 1.
When the OFF detection state is reached, the overturning delivery device 3 is overturned as shown in FIG. When the kicker 13 moves the seat support device 6 and positions it at the upper end of the overturned sending device 3 as shown in FIG. It stands up and receives the next stack of sheets 1 as shown in FIG. 5, so that the sheets 1 can be sequentially fed.

Therefore, the overturning and dispensing device is capable of extending and supporting the extension sheet in accordance with the height of the stacked sheets, and is also capable of dispensing the sheet by overturning it, and when the sheet to be sent passes through the sheet support section. The overturning and sending device can be immediately erected to load the next sheet.

Therefore, the cycle time for feeding the stacked sheets to the paper feed side can be shortened as much as possible, and it is possible to cope with high productivity of cardboard boxes and the like.

The length of the extended seat support section is preferably determined in accordance with the production schedule, since the larger the ratio of the extended seat support section to the seat support section is, the shorter the operating cycle time of the overturning and delivery device will be.

In the above embodiment, the position of the sheet delivery detection sensor is automatically tuned and variable in response to the extension of the extension sheet support section. It is also possible to control the raising and lowering of the device.

In addition, the extension sheet support section can be extended in a telescopic manner like the boom of a crane truck, or extended and retracted like a caterpillar to accommodate the height of the stacked sheets. It can be adopted as appropriate.

In addition, although a kicker was disposed in the overturning and discharging section to send out the sheets, it could be done as appropriate by disposing a conveyor or the like.

Although the above description has been made regarding sheets of corrugated paperboard, the present invention can be similarly applied to sheets such as building material boards and other sheets.

In the embodiment, in order to explain the mechanism principle in an easy-to-understand manner, the stopper for sheet delivery and the like are omitted, but it is obvious that the present invention can be applied to conventional known means.

Effects of the Invention As described above, in the present invention, since the extension seat support part is extendably disposed on the seat support part, the extension seat support part can be extended and contracted to support the sheet stacking height. Furthermore, as soon as the overturned sheet passes through the sheet supporting section, the extended sheet supporting section can be retracted and the overturning sending device can be erected, so that the sheet can be sent to the sheet feeding section with the cycle time as short as possible. This can contribute to improving production capacity.
