The length of the cut tread 1 is always shorter than a predetermined sticking circumference of the belt drum 2 to be stuck. The pressing force is calculated, for example, by the following calculation formula. Pressing force = constant + {(belt drum sticking circumference-tread measurement length) / belt drum sticking circumference} × pressure constant Here, the “constant” and “pressure constant” are empirical values.

The computer 703 uses the digital signal to D / A the information regarding the pressing force calculated in this manner.

The pressure in the cylinder 72 achieved in this way is maintained during the time when one tread 1 is attached to the belt drum 2 except when the front end portion and the rear end portion of the tread 1 are attached to the belt drum 2. It does not change.

The length correcting roller 7 which operates as described above is attached to the attaching member 9 together with the tip guiding device 6 having the vacuum pad 61, as shown in FIG. The mounting member 9 is connected to the drive shaft of the air cylinder 91 shown in FIG. 4 and reciprocates in the arrow A direction. That is, when the tread 1 is not attached to the outer peripheral surface of the belt drum 2, the length correction roller 7 and the tip guiding device 6 stop at the position shown in FIG. When the tread 1 is pasted and the length correction roller 7 presses the tread 1 against the belt drum 2, the roller 71 is placed on the center line of the belt drum 2 as shown by an imaginary line. The length correcting roller 7 and the tip guiding device 6 move so as to be positioned by the movement of the mounting member 9. Since the length correction roller 7 and the tip guide device 6 are independent mechanisms, the roller 71 and the vacuum pad 61 are independently moved up and down.

Next, the structure of the edge clamp unit 8 will be described. As described above, the edge clamp unit 8 is for minimizing the gap between the tread edge portion at the rear end portion and the front end portion of the tread 1, and for making the gap dimension as small as possible. Since the grip of the rear end portion by the edge clamp unit 8 must be released in order to attach the edge clamp unit 8 to the belt 2, it is preferable to provide the edge clamp unit 8 as close to the belt drum 2 as possible. As shown in FIG. 4, it is provided near the left end of the tread guide plate 3. 4 shows a side view of the edge clamp unit 8, and FIG. 6 shows a front view thereof. Although FIG. 6 shows only the edge clamp unit 8 that grips the left tread edge portion of the tread 1, an edge clamp unit 8 that grips the right tread edge of the tread 1 is also provided in the embodiment. .

The edge clamp unit 8 is supported by an appropriate edge clamp unit support member, and the edge clamp unit support member is supported by the structural member of the apparatus. Furthermore, the edge clamp unit 8 is
It is necessary to pull the tread 1 in the longitudinal direction of the tread 1 while gripping the tread edge portion of the tread 1.
As shown in FIG. 3, a drive shaft of, for example, an air cylinder 83 fixed to the device structural member is connected to the edge clamp unit, and the drive shaft reciprocates in the longitudinal direction of the tread 1 to move the edge clamp unit 8 to the tread 1. Move in the longitudinal direction. Since the edge clamp unit 8 is provided on each of the left and right sides as described above, the air cylinders 83 are also provided on the left and right correspondingly. Therefore, the left and right edge clamp units 8 can individually perform the pulling operation.

When the rear end of the tread 1 reaches a predetermined position, the center clamp unit 10 which rotates in the arrow B direction by the air cylinder 100 as shown in FIG. The center portion in the direction is gripped, and thereafter, the center clamp unit 10 moves while transporting the tread 1 while gripping the tread 1. Such a center clamp unit 10 performs an operation of holding the tread 1 so that the tread 1 does not shift from a predetermined position when the tread edge portion of the tread 1 is pulled by the edge clamp unit 8 described above. Then, the center clamp unit 10 releases the grip of the tread 1 after the edge clamp unit 8 releases the grip of the tread edge portion.

As shown in FIG. 8, the air cylinders 803, 804 and the air cylinder 83 are each connected to a cylinder controller 810, and the cylinder controller 810 operates in the pressing force control system of the length correction roller 7 described above. It is connected to a computer or a sequencer 703 which is a component.

The operation of the operation control system of the edge clamp unit 8 thus constructed will be described. Data relating to the shrink correction amount is input to the computer 703 in advance. The amount of shrinkage correction is a value according to the size of the tire and is an empirical value. As described above, when the rear end of the tread 1 is conveyed to the predetermined position, the cylinder controller 810 is controlled by the computer 703 to form the air cylinders 803, 8 that constitute the edge clamp units 8 on the left and right sides of the tread 1.
04 is driven and the tread edge portions on the left and right sides of the tread 1 are gripped by the edge clamps 81 and 82. Then, from the computer 703 to the cylinder controller 81
By controlling to 0, a predetermined amount of gas is supplied to the air cylinder 83 so that the drive shaft of the air cylinder 83 moves by the correction amount. Therefore, the tread edge portions on the left and right sides of the tread 1 are pulled by the edge clamp unit 8 in the longitudinal direction of the tread 1 by the correction amount.

The operation of the strip-shaped member sticking apparatus configured as described above will be described below. Belt drum 2
The tread 1 cut to a length slightly shorter than the predetermined sticking peripheral length is placed on the tread guide plate 3 by the operator, and the placed tread 1 is conveyed to the belt drum 2 direction by the drive roller 53. By passing through the installation section of the two sets of the front end detection device 52 and the rear end detection device 51 in the middle of conveyance, the tread 1 is operated by the above-mentioned operation.
The exact length in the longitudinal direction is measured. The measured length information of the tread 1 is sent to the computer 703.
In addition, the tread 1 conveyed by the centering unit 4
Centering is performed. In this way, the tread 1 extends to the vicinity of the belt drum 2 on the tread guide plate 3.
When the sheet is conveyed, the operator operates a process feed switch (not shown) to move the tread guide plate to the belt drum 2.
Move forward to approach. Next, the vacuum pad 61 descends to the upper surface of the tread 1 by the operation of the air cylinder of the tip guiding device 6, and sucks and holds the upper surface of the tip portion of the tread 1. And an air cylinder 9 for moving the mounting member 9
By the movement of 1, the mounting member advances in the direction of the belt drum 2, so that the length correction roller 7 and the tip guiding device 6 installed on the mounting member 9 advance to a predetermined position. Therefore, the tip end portion of the tread 1 sucked and held by the vacuum pad 61 is placed on the outer peripheral surface of the belt drum 2.

After the tread 1 is placed on the outer peripheral surface of the belt drum 2, the vacuum pad 61 is retracted to the upper side in the anti-tread direction after the suction is stopped, and the length correcting roller 7 is moved.
The tread 1 is pressed against the belt drum 2 by the roller 71 by the driving of the cylinder 72 constituting the. The length correction roller 7 presses the tread 1 against the belt drum 2 with the pressing force calculated and controlled by the above-described operation. With the roller 71 pressing the tread 1 against the belt drum 2 in this manner, the belt drum 2 starts rotating counterclockwise, and the tread 1 is attached to the outer peripheral surface of the belt drum 2. From each information of the rotation amount of the belt drum 2 and the measured length of the tread 1, the computer 703
The center clamp unit 10 grips the center of the rear end of the tread 1, and when the rear end of the tread 1 approaches the edge clamp, the air cylinders 803 and 804 of the edge clamp unit 8 are driven, Both ends in the width direction of the tread 1 are held by the edge clamps 81 and 82. After gripping, the computer 703 drives the air cylinder 83 and pulls the tread 1 in the direction opposite to the belt drum in the longitudinal direction of the tread 1 by a predetermined amount. After this operation, the edge clamps 81, 82 and the center clamp unit 10 release the grip of the tread 1, and the rear end portion of the tread 1 is pressed against the belt drum 2 by the length correction roller 7 while the belt drum 2 is being pressed. Affixed to the outer peripheral surface of.
At the connecting portion between the front end portion and the rear end portion of the tread 1, the pressing force of the length correction roller 7 is increased to connect the front end portion and the rear end portion. With the above operation, the attachment of the tread 1 to the belt drum 2 is completed, and the computer 703 retracts the length correction roller 7 upward in the anti-tread direction, and returns the mounting member 9 to the original position.

As described above, when the tread 1 is attached to the belt drum 2, the length correcting roller 7 is provided on the belt drum 2 so that the measured length of the tread 1 and the attachment peripheral length of the belt drum 2 match. The length of the tread 1 is changed by pressing the tread 1 against the peripheral surface and changing the pressing force. Since the length of the tread 1 is only changed by the pressing force of the length correcting roller 7 as described above, the structure of the device is simplified and no tensile force acts on the tread 1 when sticking. The tread 1 attached to the belt drum 2 does not shift.

[0026]

As described above in detail, according to the present invention, when the strip-shaped member is attached to the forming drum, the measured length of the strip-shaped member and the attaching peripheral length of the forming drum are made to coincide with each other. Since the length of the belt-shaped member is changed by pressing the belt-shaped member against the peripheral surface of the drum and changing the pressing force, only the pressing device and the control device can be used as a device for controlling the length of the belt-shaped member. Therefore, the device configuration can be simplified, and since no tensile force acts on the belt-shaped member, it is possible to prevent the belt-shaped member attached to the molding drum from being displaced.
