Description of the Related Art Generally, a rubber sheet member or the like in which a wire is inserted at a constant bias angle is used as a tire component, and a rubber sheet member formed in a long strip shape is cut into a fixed length along the wire. Each of the cut band-shaped members is wound around a forming drum, and the front and rear ends thereof are joined to form an annular member constituting a tire.

[0003] The process from cutting a fixed length of a rubber sheet member having a large number of cords embedded in parallel to pasting it to a forming drum is as follows.
This is disclosed in Japanese Patent Application Laid-Open No. 2-270542 filed by the same applicant. In the publication, a long belt-shaped member conveyed by a conveyor is passed over an anvil close to the conveyor on the way, and is cut by a cutting means for running a knife or the like on the anvil.

[0004] Since the long strip is cut parallel to the buried cord on the anvil every time the strip is conveyed for a certain distance, an end strip having less than a fixed length is usually formed at the front and rear ends of the long strip. . Conventionally, in order to remove the end piece, it was conveyed to a place where it could be easily removed by a conveyor, the apparatus was stopped for safety, and the end piece was manually removed by an operator.

[0005]

Therefore, every time the leading and trailing ends of the long band-shaped member are cut, the apparatus has to be stopped and the work of discharging the long member has to be performed, which hinders full automation. Was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a method and an apparatus for discharging an end member which enables automatic discharge of the end member.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a method in which a long strip-shaped member is conveyed at a fixed distance by a conveyer over an anvil adjacent above a conveyor, and cut on the anvil. In the method of discharging the remaining end member, a step of transporting the end member generated by cutting to a downstream side of the anvil by advancing and moving the conveyor, a step of expanding a relative vertical distance between the anvil and the conveyor, and And conveying the end member on the conveyor to the upstream side and dropping and discharging the end member from below the upstream end of the conveyor.

The end member generated by the cutting is generated at the front end and the rear end of the long strip-shaped member. In any case, the end member immediately after the cutting is partially located on the anvil, so that the end member is once downstream by the anvil. After being conveyed, the space between the anvil and the conveyor is enlarged, and then conveyed to the upstream side, so that the end member passes below the anvil and drops from the upstream end of the conveyor, and is completely discharged without requiring any manpower. Automation can be realized.

The traveling support base 45 can be moved back and forth through the protruding pieces 53 screwed with the 50.

As shown in FIG. 5 (plan view), the traveling support base 45 has a shape in which two connecting portions 45a and 45b are connected between the right and left bodies above the linear ball slide guide rail 46. The front connecting portion 45b is located at a position recessed rearward, and an elongated octagonal hole is formed between the connecting portions 45a and 45b on the left and right sides, and the side wall follows the contour of the bottom wall having such a shape. It is erected. Linear ball slide guides 47 are provided on the lower surface of the bottom wall at the four front, rear, left and right corners as described above, and are slidably fitted to the linear ball slide guide rails 46 below.

A cutting device 60 and a suction device 120 are suspended from connecting portions 45a and 45b connecting left and right sides of the center of the traveling support base 45 before and after the octagonal hole, respectively. Hereinafter, the cutting device 60 will be described with reference to FIGS.
At the center of the connecting portion 45a behind the traveling support base 45, a support plate 61 is provided between the upper ends of the front and rear side walls, and a bearing 62 is formed in the support plate 61 and a corresponding circular hole formed in a bottom wall below the support plate 61. Is fitted.

Is suspended. Below the horizontally long support frame 65 in the cutting device 60, a cylinder 71 runs along the support frame 65, and is suspended to allow movement in a direction perpendicular to the running direction. .

A disk-shaped knife 79 is rotatably supported by a rod protruding below the cylinder 71. A motor 88 is provided at one end of the support frame 65, rotation is transmitted to a pulley 84 via a speed reducer, and the cylinder 71 can run by rotation of a belt provided on the pulley 84.

A proximity switch is provided near the pulley 84. A trigger pulse is generated by the rotation of the pulley 84, and the running position of the cylinder 71, that is, the knife 79 can be detected based on the trigger pulse.

On the other hand, as shown in FIG. 5, the support frame 65 which pivots around the support shaft 64 moves in the transport direction of the belt-shaped member.
It has an angle, and at a position corresponding to an octagonal hole provided in the center of the traveling support base 45 on the front side of the support shaft 64, the round shaft 99 is supported by the support frame 65 so as to be able to move left and right. I have. A servo motor 102 provided adjacent to the round shaft 99 rotates the round shaft 9 via a toothed belt 104.

The drive of 102 causes the round shaft 99 to abut against the inner periphery of the oblong hole 106 of the bracket 105 and is prevented from moving. Conversely, the support frame 65 can be turned around the support shaft 64 by the reaction,
The cutting angle with respect to the band-shaped member can be adjusted.

The support frame 65 can be set at a cutting position by moving the traveling support base 45 in the front-rear direction, and the cutting position is on the anvil 28 shown in FIG. When the conveyor 6 is inclined parallel to the upper frame 25, the conveyor belt 12 is running close to each other between the magnet block 20 and the anvil 28 as shown in FIG. Strip-shaped member 15
Goes over the anvil 28 and stops at a predetermined position. When the cut portion is placed on the anvil 28,
Above is cut by knife 79.

Since a large number of steel cords 16 are embedded in the belt member 15 at a constant bias angle, when the cut portion of the belt member 15 is placed on the anvil 28 and the magnet block 20 is raised, the belt member 15 is lowered. The band-like member 15 can be stuck and held on the anvil 28. By cutting in this state, the belt-shaped member 15 is cut accurately.

At the time of cutting, after the knife 79 is set at a predetermined position, the knife 79 is lowered by driving the cylinder 71, and the knife 79 is placed on the side edge of the band-like member 15 held on the anvil 28.
When the blade 79 is lowered and the V-shaped cutting edge bites into the band-shaped member 15 and reaches the anvil 28, the band-shaped member 15 at the cutting edge portion is cut. At this time, if there is a steel cord 16 immediately below the cutting edge, the knife 79 movable in a direction perpendicular to the traveling direction escapes in the same direction because the reaction force of the rubber portion near the steel cord 16 is large, and eventually the adjacent one is next to the other. The steel cord 16 is not cut off by biting between the steel cords 16.

After the knife 79 bites into the side edge of the belt-shaped member 15 in this way, when the motor 88 is driven to move the knife 79, the knife 79 moves between the adjacent steel cords 16 along the steel cords 16. The cutting is continued until the other side edge of the band-shaped member 15 is reached, and the cutting is completed.

Next, another suction device suspended from the traveling support base 45 will be briefly described with reference to FIG. A support plate 121 is provided between the upper ends of the front and rear side walls at the center of the connecting portion 45b in front of the traveling support base 45, and a bearing 122 is fitted in a corresponding circular hole formed in a bottom wall below the support plate 121, Same bearing
A support shaft 124 is rotatably supported on the support shaft 124 in a vertical direction, and a support frame 125 having a horizontally long U-shaped section is fixedly supported at the lower end of the support shaft 124 at the center thereof.
It is hung horizontally and pivotally about a support shaft 124.

Square pipes 129, 130 joined to each other via a joint surface 140 are fixed to the rod tips protruding downward from a pair of cylinders 126 fixed to the left and right sides of the support frame 125, and driven by the cylinder 126. Go up and down. Square pipe 12
9 and 130 have long permanent magnets 134 and 135, respectively.
The permanent magnets 134 and 135 are formed by the cylinders 138 and 139 mounted on the square pipes 129 and 130, respectively.
It can move up and down within 129 and 130.

The suction device 120 has the above-described structure. The main body suspended by the support shaft 124 is turned around the support shaft 124 and driven by the cylinder 126 to drive the square pipes 129 and 129.
130 is moved up and down, and the permanent magnets 1 in the square pipes 129 and 130
34 and 135 can be raised and lowered independently by driving the cylinders 138 and 139. Therefore, after cutting the band-shaped member 15, the square pipe 129 is placed on the same vertical plane in accordance with the cut surface.
Position the joint surfaces 140 of the 130 and the square pipes 129, 13
When the permanent magnets 134 and 135 are lowered in the square pipes 129 and 130, the lower surfaces of the square pipes 129 and 130 are brought into contact with the lower surfaces of the square pipes 129 and 130, respectively. The front and rear ends are attracted to the lower surfaces of the square pipes 129 and 130 and lifted upward as the square pipes 129 and 130 rise.

At this time, when it is desired to attract and raise one of the end portions before and after the cut surface of the band-shaped member 15, only one magnet needs to be lowered. When releasing the suction, if the magnet is raised, the end of the band-shaped member 15 is left on the lower surface of the square pipe and can be separated. The suction device 120 and the cutting device 60 described above are both suspended from the traveling support base 45 and can always turn while maintaining a parallel state to each other as shown in FIG.

That is, the spindles 64 and 124 of each cutting device 60 and the suction device 120 are mounted on bearings 62 and 122 fixed to the traveling support base 45.
At the upper end thereof, turning arms 150 and 151 are provided with their base ends fitted in a direction parallel to each other in the horizontal direction. A connecting rod 152 is provided between the distal ends of the connecting rods 152. Both ends of the connecting rod 152 are rotatably engaged with rotating arms 150 and 151. Therefore, as described above, when the cutting device 60 is rotated by the driving of the servo motor 102, the rotation of the support shaft 64 causes the support shaft 124 to rotate via the rotation arm 150, the connecting rod 152, and the rotation arm 151 to attract the suction. The device 120 can be turned at the same speed, and the two cutting devices 60 and the suction device 120 always keep a parallel state.

Next, the suction hand 160 (see FIG. 2) provided above the upstream end of the conveyor belt 12 will be briefly described with reference to FIG. A gantry 162 is suspended long in the front-rear direction on a horizontal support frame 161 erected between the rear portions of the left and right upper frames 25, and a pair of cylinders 164 mounted on the front and rear of the gantry 162 have rod lower ends protruding downward.

The box 165 moves up and down, and the cylinder 167 mounted on the box 165
Drives the magnet 169 up and down inside the box 165.

Therefore, when the belt 15 on the conveyor belt 12 is sucked, the rod of the cylinder 164 is extended to lower the box 165 on the belt 15, and then the cylinder 16
When the rod of No. 7 is extended and the magnet 169 is lowered, the magnet
169 attracts the belt-like member 15 to the steel plate 166. When the rod 164a of the cylinder 164 is contracted in this suction state,
15 rises while being adsorbed and separates from the conveyor belt 12.

When the band member 15 is placed on the conveyor belt 12, the box member 165 is lowered and the magnet 169 is raised, so that the band member 15 is on the conveyor belt 12 and the suction is released. Is raised, the belt-shaped member 15 is placed on the conveyor belt 12.

The above is the structure of the entire sticking device for the belt-shaped member. Each driving device is controlled by a computer. Referring to FIG. 1, below the upstream end of the conveyor 6, a carriage 181 running on a rail 180 opens above the packing box and stops so as to receive the drop of the end member of the band-shaped member 15. It has become.

The conveyor 6 is rocked to return to the original inclination angle, and the belt-like member 15 attached to the drum 1 is moved.
b is removed with its ends joined together.

Then, the square pipes 129 and 130 are lowered to adsorb the next belt-like member to the conveyor belt 12 side, and the square pipe 12
When 9, 130 and the box body 165 are raised, the state returns to the state shown in FIG. Therefore, by repeating the above-mentioned operation, the cycle in which the long strip-shaped member 15 is sequentially cut to a fixed length, wound around the drum 1, the ends thereof are joined, and then removed is automatically performed.

An end member is also formed at the rear end of the long strip-shaped member 15. Discharge of the rear end member will now be described with reference to FIG. FIG. 12 (a) shows the state at the beginning of the cycle operation after the rear end end member 15d is generated by cutting at the rear end of the long band member 15 and the preceding fixed length band member 15 is processed. This is the state corresponding to FIG. 11 (h).

In this state, the conveyor belt 12 is moved forward to move the trailing end member 15d downstream, and stops when the trailing end of the trailing end member 15d is located downstream from the anvil 28. 6 (FIG. 12 (b)). Since the conveyor belt 12 is separated from the anvil 28, the conveyor belt 12 is moved backward to transport the rear end member 15d to the upstream side, and is dropped from the rear end of the conveyor 6 as shown in FIG. Collect in 181 packing box.

The conveyor 6 is swung again to the original inclination angle, and the processing of one long belt-like member 15 is completed. As described above, the discharge of the trailing end member 15d can be automatically performed without any manual operation, so that the entire apparatus can be completely automated. Although not shown, the drum 1 is located downstream of the conveyor 6.
A mechanism for causing the end member to travel in the axial direction is provided.
The method of dropping and discharging the 15a and 15d from the downstream end of the conveyor 6 is difficult because there is no room for running a truck or the like.

In the present embodiment, the anvil 28 is separated from the conveyor belt 12 by utilizing the swing of the conveyor 6 used for transferring the belt-shaped member 15 from the conveyor 6 to the drum 1 so as not to hinder the discharge of the end member. However, the anvil may be separated from the conveyor belt 12 by supporting the anvil with respect to the conveyor belt 12.

[0067]

According to the present invention, the end member immediately after cutting is once conveyed to the downstream side from the anvil, and then expanded between the anvil and the conveyor, and then conveyed to the upstream side. It passes through the lower part of the anvil and drops from the upstream end of the conveyor, and can be fully automated without any human intervention.
