Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a corrugated paper product used as one of the manufacturing processes for corrugated paper products, such as corrugated boxes.
This invention relates to a batch forming device after cutting.

Corrugated paper is formed by pasting together multiple sheets of paper, and the device that performs these pasting is generally called a corrugator, and the corrugated paper is continuously pasted together. This pasted corrugated paperboard is cut into desired dimensions to be used as a product, and must be temporarily pooled in a pallet or the like in order to be subjected to printing or box-making. To perform this temporary pooling, a predetermined number of cut cardboard sheets are stacked together and are called batches, and these batches are further stacked or arranged horizontally and temporarily stored on pallets or the like. However, the corrugated paper that has just been laminated contains a lot of water and is likely to warp during the subsequent drying process. The sheets are stacked alternately, back to back or belly to belly, in units of 40 to 40 sheets. Therefore, a small batch of 20 to 40 sheets is suitable for sending out from a corrugator. This batch formation is an extremely important part in quickly processing continuously transported corrugated paperboard and improving work efficiency.
It is also important for automation.

Batches are formed in the batch forming section by continuously transporting corrugated paperboard, dropping it into the regulating plate of the batch forming section, and stacking it at a predetermined height to form batches. This batch is then sent out from the batch forming section for the next processing step.
Conventionally, batches were not formed in an orderly manner due to the wide spacing between the regulating plates, and batches collapsed during delivery, making it impossible to stack batches. The speed of the corrugator, cutting device, etc. in the previous stage had to be slowed down, resulting in a reduction in manufacturing efficiency. In addition, if the regulating plate is made narrower to match the batch size, both ends of the batch will come into contact with the regulating plate, increasing frictional resistance. There was a drawback that it was not possible.

The present invention has been made to eliminate these drawbacks, and its purpose is to provide a batch delivery device that can form batches in an orderly manner and quickly deliver batches without collapsing the batch. It is.

The present invention has been made to achieve this purpose.
In an apparatus in which corrugated paper is continuously corrugated and cut into predetermined lengths, and the corrugated paper is continuously transported to form predetermined batches in a batch forming section for subsequent processing, the batch forming section is configured to corrugate the corrugated paper A large number of drive rolls are laid together to directly receive the batches, and a plate material is provided on the upper surface of the drive rolls to regulate at least the front side of the batch, and the plate material has a size that corresponds to the size of the batch to be formed. In addition, a batch is formed so that it can freely slide back and forth and retreat by a predetermined stroke when sending out batches, and the position of the batch can be changed arbitrarily according to the size of the corrugated paperboard on the side surface of the batch forming part. The batch delivery device is provided with an extrusion means, and configured so that the retreat of the other plate material and the extrusion of the batch are performed simultaneously and in a related manner, and the batch delivery device is configured such that the retreat of the other plate material and the extrusion of the batch are performed simultaneously in a correlated manner, It is set to become a more bat-shaped guide so that the bats are aligned in an orderly manner, and by retracting this plate material, it eliminates friction with the bats, and when sending out the bats, it is quickly and The extrusion means allows the cargo to be delivered extremely quickly without collapsing.

Next, to explain the present invention in detail with reference to the illustrated embodiment, numerals 1 to 3 are conveyors for transporting cut corrugated paperboard, which are arranged in series and have a corrugator and cutting device 4 at the front stage and a batch forming section 5 at the rear stage. In between, continuously cut corrugated paper 6
A, 6b, and 6c are continuously transferred to form a batch 7. In this case, the corrugator line speed and the driving speed of the first conveyor 1 are different, and the driving speed of the first conveyor is approximately 60% lower than the corrugator line speed, so that the corrugated paper supplied from the cutting device is cut halfway. It's starting to pile up. These conveyors are arranged adjacent to each other, and each conveyor is formed by disposing a plurality of drive belts 1a, 2a, 3a in parallel, and the drive of each conveyor is controlled.

The first conveyor 1 is always driven at a constant speed and reliably transports the corrugated paperboard continuously delivered from the corrugator and cutting device 4. The second conveyor 2 receives the cardboard transferred from the first conveyor 1 and transfers it to the next stage, that is, the third conveyor 3. This second conveyor 2 is driven at a constant speed. It is designed to alternately repeat actions such as stopping and stopping for a certain period of time (several seconds). The third conveyor 3 is configured to be driven at a constant speed or to alternately repeat fast-forward driving, and when the second conveyor 2 stops, fast-forward driving is performed. Note that the second conveyor 2 is driven at a slightly faster speed than the first conveyor 1, and the second conveyor 2 and the third conveyor 3 are driven at substantially the same speed.

The batch forming section 5 disposed downstream of the transfer conveyor includes a large number of drive rolls 8 arranged in a spread state, plate materials 9 and 10 for regulating the front and rear of the batches 7, and 7 and an extrusion means 11 for extruding it.

One of the plate materials 9 and 10, the plate material 10, is mounted on a movable frame 12 so that the regulating position can be freely changed according to the length of the batch to be formed. It is configured so that it can slide on rails 13 provided on the side and be fixed at a predetermined position using a brake or the like. It is attached to this movable frame 12 via a plurality of arms 14 and a rotating rod 15, and by rotating the rotating rod 15 by a cylinder 17 of a pneumatic pump 16, it is moved from the set position to the position shown by the imaginary line. Board material 1
Retract 0.

The extrusion means 11 is mounted on a rail 18 so as to be movable parallel to one side of the drive roll 8.
The main body 19 is placed on top, and a push plate 21 is attached to the tip of a cylinder 20 that slides by air pressure.The push plate 21 contacts the side of the batch 7 to start extrusion and remove the load at the time of start. This will prevent collapse. The pushing action of the pushing plate 21 only needs to be started when the batch 7 is delivered. Reference number 22 in the figure is a transfer line that transfers the delivered batches to a processing position for further inversion and stacking.

The batch sending device of the present invention configured as described above firstly processes the cut corrugated paperboard 6a, which is continuously fed out from the corrugated paperboard manufacturing and cutting device.
6b and 6c are, for example, three rows of transfer conveyors 1,
2 and 3, and sequentially supplied to the batch forming section 5. In this batch forming section, regulating plates 9 and 10 are positioned at a predetermined interval according to the length of the cut corrugated paperboard, so that the batches 7 are formed in an orderly manner with as little play as possible. Of course, if the sheets are well aligned, only one plate material may be used. When the batch 7 reaches a predetermined height, some of the transfer conveyors 1, 2, and 3, especially the transfer conveyor 2, stop to temporarily stop the supply of corrugated paper to the batch forming section 5. From there, the batches must be sent quickly to the transfer line 22 side. When this batch is sent out, the other regulating plate 10 is moved to the pneumatic cylinder 16.
By sliding, it quickly retreats from the regulation position (the position of the imaginary line) and releases the contact with the batch 7, and at the same time,
When the drive roller 8 is driven, the extrusion means 1
The pneumatic cylinder 20 of 1 operates, and the push plate 21 pushes out the batch 7. Since this series of operations is carried out almost simultaneously, even if the drive roller 8 is driven at a considerable speed, there is no contact between the batches 7 and the plate material 10, and furthermore, since the batches 7 are pushed out by the push-out means at an instantaneous start, There is no load collapse due to inertia during startup, and it can be delivered quickly and in an extremely good manner. After sending out the batch 7, the plate material 10 and the push plate 21 quickly return to their original positions, and the transfer conveyor 2 is driven again to continuously supply the corrugated paper to the batch forming section 5. Formation and delivery are repeated.

As explained above, the corrugated paper batch delivery device according to the present invention continuously corrugates corrugated paper, cuts it into predetermined lengths, and transports the corrugated paper to form predetermined patches for subsequent processing. In the transfer device, the batch forming section is formed by laying a large number of driving rolls that directly receive the corrugated paperboard and send out the batches in a direction substantially perpendicular to the feeding direction, and the batch forming section is formed by placing the batches on the upper surface of the driving rolls. A plate material for regulating the front and back of the batch is disposed at least at the front, and the plate material is configured to be able to freely slide back and forth according to the dimensions of the batch to be formed, and to move backward by a predetermined stroke when the batch is fed out. Furthermore, since a configuration is adopted in which a batch extrusion means is provided on the side surface of the batch forming section, the position of which can be changed arbitrarily according to the size of the corrugated paperboard, the overall configuration is significantly simplified, and repairs and maintenance inspections are made easier. This is easy, especially since the drive roll is arranged to directly receive the corrugated paper to form batches, and to deliver the batches in a direction perpendicular to the direction in which the corrugated paper is fed.
It has the excellent effect that it can be immediately discharged from the batch forming part without changing the direction, and that the discharging operation is easy and can be carried out in a short time.

In addition, a push-out means is provided on the side for ejecting the corrugated paper, and the position of the push-out means can be changed arbitrarily according to the size of the corrugated paper. The batch extrusion work can be carried out quickly and stably without causing the batch to collapse, regardless of the situation, and it also has the excellent effect of facilitating the subsequent processing work.

Furthermore, since the batches can be delivered quickly and in a short time, it is possible to speed up the corrugated paper manufacturing line at the previous stage, thereby greatly increasing production efficiency and providing corrugated paper at a lower cost. It also has excellent effects.
