2. Description of the Related Art A wrap-around type corrugated cardboard caser that wraps an integrated product while wrapping a box while forming a box from the market has been conventionally known. Such a corrugated cardboard caser is usually used for molding a corrugated cardboard case based on the outer shape of a product to be packaged, and the product is subjected to some force, so that it is suitable for packaging a product that is not easily deformed. . In addition, tight packaging is possible and the cost of the cardboard case can be reduced. In addition, the product supply direction can be set freely and the equipment layout can be rationalized.

An example of such a conventional cardboard caser will be described with reference to the drawings. 5 is an overall perspective view schematically showing a conventional corrugated cardboard caser, FIG. 6 is a plan view (a) and a side view (b) showing a conventional sheet conveying device of a corrugated cardboard caser, and FIG. It is explanatory drawing which shows the filling and delivery process of the product of a corrugated cardboard caser.

As shown in FIG. 5, a magazine 101 is formed by stacking sheets 102, and the sheets 102 are supplied from the magazine 101 one by one onto a sheet transport conveyor 112. Sheet conveyor 1
12 is a conveyor 10 for supplying the product 105 to the filling section P
3, and is configured to supply the sheet 102 to the filling unit P. Thereafter, the flap 102a and the like of the sheet 102 are folded into a boxed product 107.

[0005] As shown in FIG. 6, the sheet conveying conveyor 112 is formed so as to be able to advance and retreat by driving gears 110 and 111 which are rotated forward and backward by a driving device 109, and has a conveyor rail 113. The transport claws 114 are disposed on the conveyor section of the sheet transport conveyor 112 and press the sheet 102 during transport. The positioning stopper 115 is for determining a supply position of the sheet 102 to the filling portion P.

As shown in FIGS. 6 and 7, the positioning stopper 116 is provided on a conveying rail 119, which will be described later, to determine the position of the sheet 102 in the flow direction. Also, as shown in FIG.
The product 105 pressed and conveyed by the flight bar 118 from the conveyor 103 is formed so as to be slidable and conveyable, and has a delivery device 120 described later at the end. The flight bar 118 is driven by the chain 118a and returns to the initial position after the product 105 is filled.
The transport rail 119 is a sheet 1 filled with the product 105.
02 is transported to a downstream process, and includes the positioning stopper 116 described above.

[0007] As shown in FIG. 7, the transfer device 120 transfers the product 105 pressed and conveyed on the plate 117 by the flight bar 118 to the filling portion P of the conveying rail 119.
The end is pivotally supported by the plate 117 and is formed to be vertically swingable. Further, the transfer device 120 is connected to the rear panel 102b of the sheet 102.
Is provided with a locking claw 120a for locking the distal end portion. The case pusher 121 bends the rear panel 102b,
This is to press and convey the filled product to a downstream process.

Next, the operation of the sheet conveying apparatus will be described with reference to FIG. The sheet 102 taken out of the magazine 101 is set on a sheet transport conveyor 112. Then, the sheet 102 is pressed and conveyed by the conveying claws 114 by the operation of the sheet conveying conveyor 112 and set in the filling section P. Positioning at the filling portion P is performed by positioning stoppers 115 and 116. Thereafter, the sheet transport conveyor 112 is retracted to the initial position for transporting the next sheet 102. In addition,
During this time, the product 10 is placed on the sheet 102 in a manner described later.

Next, a process of filling and delivering the product 105 will be described with reference to FIG. As shown in FIGS. 7A and 7B, the product 105 is pressed and conveyed on the plate 117 by the flight bar 118, passes over the transfer device 120, and is filled on the sheet 102.
Thereafter, as shown in FIG.
Moves upward, and the transfer device 120 also jumps upward.

Subsequently, the rear panel 10 of the seat 102
2b is bent by the case pusher 121.
Then, the filled product is delivered to a downstream process and transported. After the sheet 102 moves by a predetermined amount, the transfer device 120 descends and returns to the initial state, as shown in FIG. Thereafter, a new sheet 102 is supplied to the filling section P, and the same process is repeated.

[0011]

However, immediately after the sheet 102 has been conveyed to the filling section P, the conveying claw 114 needs to retreat to the initial position for conveying the next new sheet 102. For this reason, the transport claw 114 is
The sheet must be slid one reciprocating movement while the cartridge 05 is filled, and the sheet conveyance speed becomes high (for example, when packing 30 boxes per minute, the speed becomes 2.5 m or more per second). Therefore, there is a problem that the lifting of the sheet 102 at the time of conveying the sheet and the poor positioning accuracy (rebound) at the time of stopping by the positioning stopper 115 are likely to occur, so that stable operation becomes difficult.

Further, since it is necessary to change the starting position of the conveying claw 114 for each sheet size, there is a problem in that the starting position change control, type change, and adjustment for each type are troublesome.

Further, by increasing the sheet conveying speed,
There were also problems such as an increase in mechanical noise and a reduction in the life of each operating part.

Further, as described above, after the product 105 is pressed and conveyed to the filling portion P by the flight bar 118,
The product 105 is temporarily stopped, and is delivered to the case transporting process by being pressed by the case pusher 121. Therefore, there is a problem that a change in the handling speed of the product 105 is very large, and the behavior is likely to be unstable at the time of delivery. Was.

Further, since the transfer device 120 swings up and down, the structure of the device is complicated, the vibration is increased, and the durability and reliability of the device are reduced. There was a problem that it decreased.

Further, unless the delivery device 120 returns to the initial position, the next product 105 cannot be supplied, so that it is difficult to improve the operation ability and the speed cannot be increased.

Also, due to the structure of the delivery device 120, the product 105 pressed and conveyed by the flight bar 118 is provided.
Moves from the transfer device 120 onto the sheet 102,
There is also a problem that the vehicle may fall due to a step or a change in friction coefficient.

The present invention has been made in view of the above, and realizes a stable and quick box packing operation with a simple configuration, can easily cope with various sheet sizes, and has low noise, durability and reliability. It is an object of the present invention to provide a corrugated cardboard caser capable of improving the performance.

In order to achieve the above-mentioned object, a cardboard caser according to claim 1 of the present invention comprises:
A sheet conveying conveyor for supplying a sheet to a filling section for filling the product, and a sheet conveying conveyor arranged to be movable forward and backward on the upstream side of the filling section and formed so as to be disposed on the sheet upper surface side of the filling section with the product placed thereon. A mobile plate, and a drag plate that is disposed on the downstream side of the filling unit so as to be able to advance and retreat, and is formed so as to be arranged on the lower surface side of the sheet filled with the product. The sheet in the filling section is conveyed and filled, and the sheet filled with the product is conveyed downstream by the drag plate.

A mobile plate on which a product is placed is placed on the sheet supplied to the filling section by the sheet transport conveyor, and the product is filled. As a result, the product and the sheet can be filled in close contact with each other, so that the product is unlikely to tip over and stable filling can be performed. The sheet filled with the product is transported downstream by the drag plate. As a result, it is possible to avoid the conventional conveyance with a large speed difference, and to perform a stable conveyance and delivery operation. Since the mobile plate and the drag plate adopt a method of moving forward and backward in the horizontal direction, and do not employ the conventional vertical swinging method, a simple device configuration can be achieved, and the device can be made compact.

The sheet is supplied to the filling section while being sucked. The positioning of the sheet in the filling section is performed by operating the sheet conveying conveyor for a predetermined stroke or more, bringing only the sheet into contact with the stopper, and slipping the sheet on the conveyor. After the sheet is conveyed, the conveyor stops immediately to prepare for the next conveyance.

By adopting the suction type, the sheet conveyance start position is arbitrary. For this reason, the transport speed control and the device configuration can be facilitated. Further, since the conveyor is operated only in the direction of the filling section, there is no retreating movement as in the prior art, and time loss can be avoided, so that the transport speed can be reduced accordingly. Therefore, it is possible to effectively prevent the sheet from being lifted up or a positioning defect, which has conventionally occurred, and to stably convey and supply the sheet.

According to a third aspect of the present invention, there is provided a corrugated cardboard caser having a flight bar which presses and conveys a product on a mobile plate onto a sheet in a filling section, and the flight bar places the product on a sheet in the filling section. The mobile plate is retracted while being moved, and the product is filled on the sheet.

The flight bar is driven by, for example, a chain, and after the product is filled, rises once and returns to the initial position. The product is pressed and conveyed to the filling portion by the flight bar and the mobile plate is retracted, so that the product is simply and quickly filled on the sheet.

According to a fourth aspect of the present invention, there is provided a corrugated cardboard caser, wherein at least a finish folding / conveying device for performing sheet conveyance, flap folding, and panel folding is disposed downstream of the drag plate, and is configured to handle a sheet filled with a product. The loaded drag plate is accommodated in the finish folding / conveying device at the time of retreat.

Since the arm-shaped drag plate can be stored in the transfer rail of the finishing folding transfer device,
