Abstract

PURPOSE:To contrive to increase the productivity of a device by a method wherein the rear end of old material and the front end of new material are automatically joined together by delivering the front end of the rolled new material to the proper position by means of a material feeding device so as to lap over the rear end of the held old material and, after that, releasing the holding of the old material. CONSTITUTION:When the rear end of the material 4 of a material truck C1-2 passes a roll 8, material feeding conveying devices dd and ee are stopped, an arm 33 is rocked by a cylinder 36 so as to suck a material 4 with the suction cups of the arm 33 and the arm 33 is evacuated upwards by raising a cylinder 35. After the retreat of the material truck C1-2, a next material truck C1-2 advances to the position so as to deliver a new material 4 by the predetermined amount from a roll 5. At that time, the arm 33 is moved back by contracting the cylinder 35 so as to adherently join the sucked rear end of the old material to the front end of the new material through the rocking movement developed by the cylinder 36. Finally, after the release of the vacuum suction, the arm 33 is raised. Thus, the automatic operation becomes possible, resulting in allowing to contrive to increase the productivity of a material feeding device.

A side view and a top view of the material alignment device (also shown in Fig. 3-2) are shown.

The following explanation will be given using the material cart C1-2 as a substitute.

The material cart C1-2 is composed of the following.

Automatic material exchange system ■-1 roller and bearing 2. Bearing fixed to sled-shaped pedestal 1 that is conveniently slid on bearing ball 1. A material roll 5 on which a liner 3 and a material 4 are co-wound are rotatably mounted. A bearing 675 is arranged parallel to the roll 5 and mounted on the pedestal l! : A liner roll 7 rotatably mounted through the liner roll 7, and a separate roller 8 disposed between the rolls 5 and 7. and a material alignment device installed upright on the pedestal 1.

The material roll 5 and the liner roll 7 are each equipped with a coupling clutch 9 at their shaft ends, and when the material cart is installed at a predetermined position.

It is connected to the output shaft end 10 of the material feeding device of the material supplying device CI in a transverse manner.

This situation is also shown in FIG.

The material alignment device consists of the following:

1-1 is a flat plate erected on the pedestal 1.

12 is a bearing fixed to this flat plate 11, and a guide shaft 13
．． I4 are supported in parallel.

The guide shaft includes a slidable bearing box 15 and guide 9 plates 16, 21 . Racks 17.22 are mounted. Each rack is meshed with two onions 18 in the middle, and the pinions 18 are normally 2.

The guide plates 16.21 are biased by a spiral spring (not shown) so as to be expanded (as shown by solid lines).

The flat plate 11 is equipped with a plate 19 having a shape suitable for the flow of the material 4 and a bearing 20 that is slidable in all directions.

The bearing boxes 15 are connected by connecting rods 23, and 5 connecting rods 2

A cylinder 25, which can be arbitrarily pressed against the end of the rod 24, is fixed at a suitable position in the material delivery device 1tc1-i.

According to this structure, the guide plate 16 for aligning the materials,
21 is usually widened enough to the width of the material so as not to impede the flow of the material.

Therefore, the cylinder 25 is extended at the required time and the rod 2
If you push 4 by overcoming the spring (not shown), you will get rank 1.
7.22 and the action of the pinion 18, the guide 9 plates 16, 21 can be symmetrically reduced in width, and the width of the guide 9 plates 16, 21 can be reduced symmetrically, so that the width of the guide 9 plates 16, 21 can be reduced to the correct width at the tip end at the beginning of use of the material or at the rear end near the end of use p. can be aligned in the central part 11 of.

Also, if the cylinder 25 is retracted, the guide plate 16,
21 can be expanded again.

The cylinders 35 and 36 are then retracted, and the fifth illustrated state represents a normal production operation.

Cylinder 35 is in a contracted state (as shown) and cylinder 36
When is in an extended state (- point shown in detail).

It shows a state where the rear end of the material is being suctioned and held, and a state where the held rear end of the material is being joined to the next new front end of the material and the holding is being released.

That is.

When a known optical sensor (not shown) detects that the rear end of the material has passed through the roll 8 portion of the material cart near the working length p, the cylinder 25 shown in FIG. 6 is extended, and the guide plate 16. 2I of the material supply device.
Second. At the same time as the feeding of the third and fourth conveyors is stopped, the material feeding operation of the material cart is also stopped.

After that, we worked hard to unload the material carts.

Feed the material until the rear end of the material is in the proper position.

When a known optical sensor (not shown) detects that the appropriate position has been reached, the arm 33 swings and the vacuum cup 34
The material is absorbed by the arm 33, and the arm 33 rises again.

Thereafter, the cylinder 35 extends and swings while holding the material until it reaches the state indicated by the dotted line in FIG. 4, waiting for a new material truck to enter.

When the advance of the cart is completed and the new material is sent out, and the optical sensor detects the tip of the material, the loading of the material is stopped, and the material on the new material cart is transferred to the cylinder 25 as described above. The alignment device is activated to align the leading edges of the material.

Thereafter, the cylinder 35 is retracted by -1 (, the arm 33 holding the rear end of the material returns to its original position, and then the cylinder 33 returns the arm 33 to its original position (FIG. 5)).
A trailing end of the material is adhesively bonded to the leading end of the material.

The vacuum is then released, the arm rises again, and the guide plates 16.21 are expanded to a position where they do not impede the flow of material.

According to the above method, the leading and trailing ends of the materials can be joined automatically, and manual work by the operator is not required.

The cutting device 11 works to cut a material into a predetermined length for each tire during normal production operation.

When the new and old material carts are replaced, cut the front and back of the joints of the new and old material slanted ends that were joined at the material alignment device part of the material cart, and discard the cut pieces including the joints outside the mounting. , it can be used to fully rejoin the cut ends.

In general, the shape of the material was unstable at the beginning of use and near the end of use of the roll-shaped material, especially in the case of steel corded parts, the wire was exposed at the end surface. In many cases, it is inconvenient to insert the cutter into the tire as it is, and the method and cutting device according to the present invention work effectively.

According to such a configuration, after the cutting, the barb on the rear side of the cutting line is raised by 1-1 in the vicinity and further back along the cutting line, and at a shilling of -63, it is possible to retire immediately. , it can be moved forward again and accurately pulled to the first suction and fi two positions.Also, the angle of the material to be cut may change depending on the specifications of the tire, so the cutting line and suction position may vary slightly. However, it is possible to maintain a parallel position along the cutting line. Furthermore, if it becomes necessary to maintain a constant relationship between this cutting line and the suction position.

By replacing the Schilling-63 with a known special cylinder that is related to control, it is possible to cope with changes in the angular dimensions of the material.

Fig. 11 schematically shows the state seen from above the material aligning device and cutting device of the material cart, and shows the welding of the problem end of the material cart at the end of use and the material end at the beginning of use of a new cart. The work procedure for removing and rejoining the joined portion in the cutting device section is shown.

Work procedure (see Figure 11) (a) The first sensor detects that the rear end of the material 4 on the N material cart 11 has come to the material alignment device, and the material feeding force is temporarily stopped. 16°21 is the guide plate of the Nth truck.

(b) After stopping, the width of the guide plate 16.21 is reduced to align the materials. After further alignment, material 4.

It moves up to the second sensor and stops.

(c) The guide plates 16 and 21 are attracted by the vacuum pad 34, and then the guide plates 16 and 21 are expanded. Next, the adsorbed material is brought into the state shown by the dotted line in FIG. 4 by the swinging of the arms 30 and 33.

(b) A new (N+1) golden material, licorice, enters and is placed, and the material starts to be used and is fed out from the material roll. At this time, the guide plate 16°21 is expanded.

This guide plate is the guide plate of the (N+i) gold-colored truck.

(e) The first sensor detects that the end of the material has come to the material alignment device, and temporarily stops the material feeding force.

The guide plates 16 and 21 are then narrowed to align the materials. The material is then inched forward until the second sensor detects it.

(F) After stopping, the rear end of the material of the 5Nth material cart is set as the original section, and is overlapped with the leading end of the pewter material (N+l) and adhered. After this, will 6 Bakyumpad 34 be stratified? : Released and set to standby position.

(g) At the same time, the guide plates 16.21 are expanded and the material 4 is appropriately advanced and used.

(a) The joint of the material reaches the cutting device, passes the appropriate amount to the cutting position, and then stops.

Reference numeral 57 indicates a material pedestal, and the dashed-dotted line indicates the line to be cut.

(Man: The disc knife 53 is pressed and travels in the cutting direction to cut the material 4.

Thereafter, the vacuum pad 76 attracts the rear part of the cutting line and rises.

(3c) After ascending, retreat backwards.

(b) The material in front retreats and the joint stops when it detects the planned cutting line.

At this time, the material absorbed by the vacuum pad 76 is prevented from coming into contact with the conveyor, and the disc knife 53 is pressed and runs in the cutting direction.
Cut material 4.

(2) Next, when the first disc knife returns to the center, the cuum pad 60 adsorbs the cut piece 4' including the joint, rises, travels in the cutting direction again, and adsorbs the cut piece at an appropriate position. Release and discharge.

Φ) The end of the material that has been suctioned and held moves forward again, is lowered and placed at the original position, and is released from the vacuum pad 76. The retaining device is retracted to an unobstructed position.

(Y) Next, the press roll 55 descends and runs while pressing, joining both materials at the cutting line.

It should be noted that, although the above description has been made regarding an embodiment related to a breaker ply, the present invention can be applied to cutting materials stocked in a roll shape, regardless of the presence or absence of steel cords within the material.

〔Effect of the invention〕

The process of replacing material carts, terminal processing and joining of new and old materials, which were previously done manually, can now be operated automatically, making it possible to create highly productive equipment.
