[Prior art]
This kind of ply cord has a different bias angle on the front and back, and when supplying it to the processing point such as the place to be attached to the reinforcement object such as an elastic rubber air suspension, supply the front side with the bias angle facing upward There is a case where it is necessary to supply the bias with the bias angle on the back side facing upward.
[0003]
Conventionally, as a means for responding to these two request cases, generally, a dedicated material is prepared for each request case, and a ply cord cut to a predetermined size from each material is cut into a cutting device, a transfer device, and a conveyor. Means have been adopted in which a dedicated servicer including a drive motor, a conveyor support stand, and the like is used to convey and supply to a predetermined attachment point.
[0004]
[Problems to be solved by the invention]
However, in the case of the conventional countermeasures as described above, since it is necessary to install two types of dedicated ply cord servicers, not only the required installation space is large and the entire equipment becomes large, but also the introduction cost is high. It is inevitable to become.
[0005]
In addition, since two types of raw fabrics themselves must be prepared, the number of steps for changing the material in the material preparation process is increased, which is disadvantageous in terms of workability.
[0006]
The present invention has been made in view of the above circumstances, and enables the same raw material and a kind of servicer to be used for supplying ply cords having different bias angles, so that the entire equipment can be reduced in size, space can be saved, and introduction costs can be reduced. It is a main object of the present invention to provide a ply cord reversing / transporting device capable of reducing the number of steps for changing a material in a material preparation process.
[0007]
Another object of the present invention, in addition to the above object, is to enable a ply cord to be supplied to a predetermined sticking point without bending or wrinkling at the end thereof.
[0008]
[Means for Solving the Problems]
In order to achieve the main object, a ply cord reversing / conveying device according to claim 1 of the present invention is configured to place ply cords having different bias angles on the front and back and cut to a predetermined size from a raw material. An upper conveyor that conveys in a certain direction, a lower conveyor that conveys by transferring the ply cord carried out from the conveyance end of the upper conveyor, and a servomotor that separately drives the upper conveyor and the lower conveyor, A first state in which the upper conveyor and the lower conveyor are both driven in the same transport direction to supply the ply cord to a predetermined processing location while maintaining the same bias angle as the raw material, and unloading from the transport end of the upper conveyor. When the ply cord is transferred to the lower conveyor, the lower conveyor is driven in the direction opposite to that of the upper conveyor to turn the ply cord upside down. The servomotor which switches the transport direction of the lower conveyor and switches to the second state in which the ply cord, which has been turned upside down, is supplied to the predetermined processing location at a bias angle different from that of the original. A drive control means is provided.
[0009]
According to the present invention having the above configuration, by controlling the transport direction of the upper conveyor and the lower conveyor and the drive timing of these conveyors through the servo motor drive control means, the ply cord is kept at the same bias angle as the original web. The first state in which the sheet is transported and supplied to a predetermined processing location (code sticking point), and the paper is transported and supplied to the predetermined processing point (code pasting point) at a bias angle different from that of the original sheet by turning the front and back during the transport. It is possible to arbitrarily switch to the second state. That is, a kind of ply cord servicer including the same raw material and cutting device, transfer device, upper and lower conveyors, servo motors for driving them, conveyor support frame, etc., is used for supplying ply cords having different bias angles. This makes it possible to reduce the size of the entire equipment, save space, and reduce the introduction cost. In addition, with the use of the same raw material, the number of man-hours required for changing the material in the material preparation process can be halved compared to the conventional method, and the ply cord supply workability can be improved.
[0010]
In particular, as described in claim 2, when the servo motor drive control means is switched to the second state, the leading end of the ply cord carried out from the transport end of the upper conveyor contacts the lower conveyor. In this state, the driving of the upper conveyor is temporarily stopped, and in this stopped state, the driving of the lower conveyor is started in the conveyance direction opposite to the upper conveyor, the tip of the ply cord is paid, and immediately after that, the driving of the upper conveyor is restarted. In the case of configuring, when the ply cord is turned upside down in the middle of the conveyance, it is possible to move the leading end of the ply cord to the lower conveyor side with good timing by the lower conveyor, and the ply cord may be bent or wrinkled. Can be prevented.
[0011]
In addition, as means for detecting that the tip of the ply cord unloaded from the transfer end of the upper conveyor has contacted the lower conveyor, the time from when the upper conveyor starts driving until it stops temporarily is determined by the type of ply cord. May be detected manually by measuring the set time, but in this case, when the length of the ply cord changes, or when the conveyor moving speed is changed to shorten the supply cycle, etc. Each time, it is necessary for the operator to calculate and change the set time of the timer.
[0012]
On the other hand, as described in claim 3, as the servo motor drive control means, the contact of the leading end of the ply cord unloaded from the transfer end of the upper conveyor with the lower conveyor is determined by the length of the ply cord and the upper conveyor. Detects by counting the transport distance calculated from the moving speed of the conveyor and controls the driving of the upper conveyor and the lower conveyor, so that the work can be performed even when the length of the ply cord or the conveyor moving speed is changed It is possible to accurately detect the contact of the tip of the ply cord and perform a good front / back reversal function without bending, wrinkling, etc. without requiring any trouble of a member, complicated calculation or trouble of setting a timer.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 3 are side views showing a schematic configuration of a main part of a ply cord reversing / transporting device according to the present invention in a ply cord servicer, and FIGS. 2 and 4 are plan views showing a schematic configuration of the main part. The ply cord inverting / transporting apparatus A is configured to cut a ply cord 1 cut from a raw material to a predetermined size by a cutting device (not shown) and supplied by a transfer device (not shown) using a suction cup or the like. An upper conveyor 2 such as a belt conveyor suspended along a horizontal plane so as to be placed and transported in a fixed direction indicated by an arrow x, and a lower portion of the upper conveyor 2 over a range longer than the upper conveyor 2. A lower conveyor 3 such as a belt conveyor for transferring and transferring the ply cords 1 which are suspended along a horizontal plane and conveyed from the conveying terminal end of the upper conveyor 2; Servo motors 4 and 5 for individually driving the stage conveyor 3 and a gantry (not shown) for erection and support of the upper conveyor 2 and the lower conveyor 3 at appropriate working height positions on the floor surface. is there.
[0014]
The servo motors 4 and 5 are linked to a servo motor drive control controller 6 for controlling the drive / stop and rotation direction of the servo motors 4 and 5. As shown in FIGS. 1 and 2, the controller 6 drives the upper conveyor 2 and the lower conveyor 3 together in the same transport direction x1, x2 at the same speed to drive the ply cord 1 at the same bias angle as the original. The first state in which the lower conveyor 3 is conveyed and supplied to a code sticking processing point P formed continuously with the end portion in the conveying direction x1 of the lower conveyor 3 and the conveyance of the upper conveyor 2 as shown in FIGS. When the ply cord 1 carried out from the terminal end is transferred to the lower conveyor 3 and the leading end 1e of the ply cord 1 contacts the mounting surface of the lower conveyor 3, the driving of the upper conveyor 2 is temporarily stopped, In this stopped state, the lower conveyor 3 starts to be driven in the conveying direction indicated by the arrow y opposite to the upper conveyor 2, and the leading end of the ply cord 1 is paid by the lower conveyor 3, and immediately thereafter, the upper conveyor 2 is driven. By resuming the operation, the front and back of the ply cord 1 are reversed, and then the conveying direction of the lower conveyor 3 is switched from the arrow y to x2, and the ply cord 1 whose front and back are reversed is biased at a bias angle different from that of the original. And the second state in which the sheet is conveyed and supplied to the above-mentioned code sticking processing point P formed continuously with the end portion in the conveyance direction x2.
[0015]
Here, the length of the ply cord 1 and the movement of the upper conveyor 2 are used as detecting means for detecting that the leading end 1e of the ply cord 1 unloaded from the transfer end of the upper conveyor 2 has contacted the mounting surface of the lower conveyor 3. The controller 6 is provided with a calculating means and a counting means so as to detect automatically by counting the transport distance calculated from the speed. The driving stop time of the upper conveyor 2 when the leading end 1e of the ply cord 1 contacts the mounting surface of the lower conveyor 3 is set to about 1 to 2 seconds.
[0016]
In the ply cord reversing / transporting apparatus A configured as described above, the ply cord 1 is controlled by controlling the transport direction of the upper conveyor 2 and the lower conveyor 3 and the drive timing of the conveyors 2 and 3 via the controller 6. In the first state in which the ply cord 1 is transported and supplied to a predetermined code sticking processing point P while maintaining the same bias angle as that of the raw material, and a predetermined bias angle different from that of the raw material is obtained by reversing the front and back of the ply cord 1 during the transportation. Since it is possible to arbitrarily switch to the second state in which the ply cords 1 are conveyed to and supplied to the code sticking processing point P, when sequentially supplying the ply cords 1 having different bias angles to the predetermined code sticking processing point P, the same material is used. And a reversing device including a cutting device, a transfer device, upper and lower conveyors 2 and 3, servomotors 4 and 5 for driving them, a conveyor support base, and the like. It can be shared by ply cords servicer kind comprising conveying apparatus A, thereby, miniaturization of the whole equipment, space saving and the introduction cost of the attained. Also, with the use of the same raw material, the number of man-hours required for the step of changing the material in the material preparation process can be halved as compared with the related art, and the ply cord supply workability can be improved.
[0017]
Further, when the ply cord 1 is turned upside down and transported to a predetermined code affixing point P to be conveyed and supplied to the second state, when the leading end 1e of the ply cord 1 comes into contact with the mounting surface of the lower conveyor 3 When the driving of the upper conveyor 2 is temporarily stopped, and the lower conveyor 3 is started to be driven in the conveying direction y opposite to that of the upper conveyor 2 in this stopped state, when the front and back of the ply cord 1 are reversed during the conveyance, The leading end 1e can be wiped with good timing by the lower conveyor 3, and the ply cord 1 can be smoothly and satisfactorily transferred to the lower conveyor 3 without generating bending or wrinkles.
[0018]
In the above embodiment, in the first state in which the ply cord 1 is conveyed and supplied to the predetermined code sticking processing point P while maintaining the same bias angle as that of the raw material, the upper conveyor 2 and the lower conveyor 3 are the same. The case of simultaneous driving in the transport directions x1 and x2 has been described, but the ply cord 1 is transported by the upper conveyor 2 to near the transport end using the arithmetic means and counting means provided in the controller 6. At this point, the lower conveyor 3 may be started to be driven in the same transport direction x2 as the upper conveyor 2.
[0019]
Further, after the leading end 1e of the ply cord 1 is transferred from the upper conveyor 2 to the lower conveyor 3, the moving speed of the lower conveyor 3 is slightly higher than that of the upper conveyor 2 so that the ply cord 1 is slightly pulled. Thereby, generation of wrinkles can be more reliably prevented.
[0020]
【The invention's effect】
As described above, according to the present invention, it is possible to have the function of reversing the ply cord by controlling the transfer direction of the upper and lower conveyors and the drive timing of the conveyors by switching. A kind of servicer including the reversing / transporting device can be used for supplying ply cords with different bias angles, which can reduce the size of the entire equipment, save space and reduce the introduction cost, and reduce the cost in the material preparation process. There is an effect that the ply cord supply workability can be improved by reducing the number of man-hours for changing the steps.
[0021]
In particular, by using the servo motor drive control means having the configuration as described in claim 2, when the ply cord is turned upside down in the middle of the conveyance by the conveyor, the leading end portion of the ply cord is paid by the lower conveyor with good timing to the lower conveyor side. The ply cord can be transferred, thereby preventing the ply cord from being bent or wrinkled.
