[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forming a core alignment body having a predetermined length by connecting slitted web winding cores sequentially with spacers.

[0002]

2. Description of the Related Art As shown in FIG. 1, a strip 2 pulled out from a roll 1 is cut into a predetermined width by a pair of trimming blades 3 and a plurality of slitter blades 4, and a web 5 formed is paired. In the winder wound around a plurality of cores a set between the winding drums 6, a pair of chuck devices are supported so that the plurality of cores a on the winding drum 6 can be moved up and down along a column 7. There is a shaftless winder that is clamped from both sides by 8.

In the case of the above-mentioned shaftless type winder, a plurality of cores a arranged in the axial direction are integrated by chucking a pair of chuck devices 8, but due to misalignment between cores a, vibration and the like. During the winding operation, a part of the core a could jump out, which was extremely dangerous.

To form such a problem, FIG.
As shown in FIG. 1, adjacent cores a are connected by spacers b to be integrated.

[0005]

By the way, in forming the core alignment body A in which a plurality of cores a are connected by spacers b, conventionally, the spacers are manually inserted inside the cores. It took a lot of time to form the alignments.

An object of the present invention is to solve the above-mentioned disadvantages and to automate the formation of the core alignment body.

[0007]

A core supply device for supplying cores one by one to the table, a pusher device for pressing the end face of the core supplied on the table to move the core forward by a constant stroke toward the other end of the table, and a constant stroke fed by the pusher device. It has a core holding device that presses the core against the upper surface of the table, and a chuck for holding the spacer that stops at a predetermined position on one side of the core table. The spacer held by the chuck is the back of the core held by the core holding device. And a spacer supply device that transports the paper to the core transport line.

[0008]

In the forming apparatus having the above-described structure, the core supplied from the core supply device onto the table is conveyed in the axial direction by a predetermined stroke by the operation of the pusher device. The operation of pressing the upper surface and the operation of transporting the spacer held by the chuck onto the transport line of the core are repeatedly performed to insert the spacer inside the end of the core, and a plurality of cores are sequentially connected by the spacer.

When the second core a ₂ is transported below the core holding device 50, the pusher 46 returns to the original position,
On the other hand, it presses the second core a ₂ core retainer 54 of the core holding device 50 is lowered to the core table 20.

Thereafter, the operations shown in FIGS. 10C to 10F are repeated, and the core alignment body A shown in FIG. 11 is formed by repeating the operations.

The core alignment body A is moved from the core table 20 by the driving of the servo motor 42 of the pusher device 40 and the operation of the cylinder 44 to the core loading section 11 of the winder.
The web 5 is fed from the core feeding section 11 to a space between the pair of winding drums 6 to wind the web 5.

When the web roll B having a predetermined diameter is formed by the winder, the web roll B is discharged onto the first conveyor 90 from between the pair of winding drums 6.

Upon receiving the web roll B, the first conveyor 90 conveys the web roll B toward the second conveyor 92. The head of the web roll B ₁ is as shown in FIG. 1, the second conveyor 92
When fed into the upper, first conveyor 90 is stopped, and its first conveyor 90 by the relative movement of the second conveyor 92, the beginning of the web roll B ₁ represents is separated from subsequent web roll B. At this time, a spacer b that was connected to the core a rest at the top of the web roll B _1, the spacer b is a spacer extractor 100 chucks 101A
When facing the lower part of the transfer path in the front-back movement direction, the second conveyor 9
2 stops.

When the second conveyor 92 stops, the chuck 101A of the spacer removing device 100, which is waiting on the spacer b in advance, descends. The chuck 101A is sandwiched a spacer b by actuation of the cylinder 115, the second conveyor 92 transports the web roll B ₁ operates.

[0061] Spacers b is withdrawn from the web roll B ₁ by the relative movement of the web roll B ₁ and the spacer b, the spacer b is linear slide device for lifting and lowering 1
The sheet is conveyed onto the spacer conveyor 60 by the operation of the front slide 01B and the operation of the linear slide device 101C for forward and backward movement, and is discharged to the discharge end by the spacer conveyor 60.
