Forming machine to form cardboard boxes from blanks
It is about. [0002] 2. Description of the Related Art In general, an outer corrugated board for packaging products.
The material for forming the box is manufactured by a cardboard manufacturer,
The cardboard manufacturer transports the cardboard box to the customer,
It is formed. FIG. 24 shows a forming element for forming a cardboard box.
An example of the production of materials is shown, each with a different and separate device.
It comprises the following steps: [0004] First step There is a double-sided cardboard sheet formed by corrugator
Or double-sided corrugated cardboard sheet with slitter to required width
Cut to dimensions and cut the continuous cardboard sheet after cutting.
Cut to the required length with a rotary cutter, and
As shown in (I), a rectangular cardboard sheet S₀Form
I do. This corrugated cardboard sheet S₀To the corrugator outlet
At the appropriate height. [0005] Second step Corrugated cardboard sheet S obtained in the first step₀Figure 24
It is transported to the punching device shown in (II), supplied, punched, and the side edge is cut.
Two horizontal ruled lines parallel to and a plurality of vertical lines perpendicular thereto
Blank as a material for forming cardboard boxes with ruled lines
S₁To form FIG. 25 shows a block formed by a punching device.

Flat box S shown in FIG. 24 (III) _TwoTo form Fourth step Flat box S_TwoTo the binding machine shown in Fig. 24 (IV).
Then, a predetermined number of sheets are stacked and bound by a band Y. S_Three
Indicates a bound box. Fifth step Bound box S_ThreeTo the palletizer shown in FIG.
Conveyed, supplied, and stacked on pallet X at a specified height
You. On the pallet X through the first to fifth steps
Boxes S stacked on each other_ThreeIs transported to customers by truck
Installed at the customer's factory to pack the contents
As shown in FIG. 24 (VI), a box forming device
Box S_FourAssembled. Here, the cardboard box S_FourForming a box
The device is described in, for example, Japanese Patent Publication No. 57-33207.
As shown, the flat box S_TwoBecomes a square tube
After assembling, the inner flap f_TwoBend inward,
Outside flap f_FourBend inward and overlap each other
Fit inside flap f_TwoAnd outer flap f_FourAnd glue
I have to. [0014] By the way, the above conventional art
In manufacturing, the flat box formed in the third step
Body S_TwoIs the inner flap f₁, F_TwoAnd outer flap f_Three, F
_FourAt the overlapping portion, a two-layer structure is formed, and at the other portion,
It is a laminated structure of layers and the thickness is thick at the center in the width direction.
Since the side is thin, the box S_TwoMultiple sheets
When bound and tied together, the bound box S_ThreeIs the width direction
There will be a big swell in the center. [0015] For this reason, in the fifth step, binding on the pallet X
Box S_ThreeWhen the boxes are stacked at the specified height,
S_ThreeIs not stable enough to ship to customers or receive
Collapse occurred during the injury, which was extremely dangerous. The bound box S on the pallet X_Three
The pallet X can be stacked because the stability of
Wound, Box S_TwoDo not secure a large space for transporting and storing
There was also a problem that it had to be done. In particular, cardboard manufacturers use
Therefore blank S₁Is a flat box S _TwoWhen forming into

The occurrence rate of products is extremely high.
There is a problem that a product is generated and a loss rate is high. The present invention relates to a material for forming a cardboard box.
Can be safely transported or stored for customers
And greatly reduce the rate of defective products.
The customer is blank to be able to
From a box that allows you to assemble a cardboard box from
It is a technical object to provide a forming apparatus. [0019] Means for Solving the Problems To solve the above problems,
In the present invention, a square tubular body of a box is formed.
Flat panels that are connected in one direction through ruled lines
Paper feed unit that supplies flat box forming blanks one by one
And two intermediate parts of the blank supplied from the paper feed unit
Each of the panels connected to both ends of the panel
When transport of ink is stoppedBent almost 90 ° to make the blank concave
And then bend the flap further inward 90 °
,Adhes the overlapping ends to form a flat box
From the flat box forming unit and the flat box forming unit
From the five flat panel panels that were sent,
It is formed in a square cylindrical shape, and a ruled line is
90 ° bent inward in multiple flaps
To form the bottom wall of the box to form a square box
And the square box forming unit
is there. With the above configuration, the customer can
Since the cardboard box can be assembled from the state of
Ball maker stacks and binds multiple flat boxes
Process and stacking the bound boxes on a pallet
A step can be eliminated. For this reason, cardboard manufacturers use blanks.
It is only necessary to stack on pallets and deliver to customers.
Safely transport or store the material used to form the box
be able to. In the customer, the formed cardboard
Flat box according to the box packing time
Can take enough time to form
Can be bent with the transport stopped.
Wear. For this reason, the blank is folded very accurately.
It can be folded, greatly reducing the incidence of defective products.
Can be. Further, in the customer, according to the required quantity,
It is only necessary to form a flat box
Can be saved and efficiency is high. [0025] [0026] BRIEF DESCRIPTION OF THE DRAWINGS FIG.

There is no need to do so, and the device can be shortened. [0115] As described above, according to the present invention,
As we started to assemble the cardboard box from the rank,
At the maker, several flat boxes are stacked and bound.
Process and stacking united boxes on pallets
The brass material used to form the box
Link can be transported safely. A flat box is formed by bending a blank.
In the process of forming the body, it is inserted inside the cardboard box
Because it is only necessary to form a box according to the packing of the contents,
Bending over time with blank transport stopped
Can be bent with high accuracy, and
The production rate can be greatly reduced. Further, according to the quantity required for packing the contents
Can be used to form a box.
Not required and efficient. [0118]
