Description

Tire Bead Feeding System {Tire Bead Material Handling System}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed supply device for tire beads, and more particularly, to an apparatus for automatically transporting a bead, which is a tire semi-finished product, by a predetermined amount and automatically supplying the molding machine.

In the conventional tire bead feeding and feeding device, the finished bead is hanged on the bead hanger by hand and waited for a predetermined time, and then the bead is transported to the molding machine at the time of tire molding, and then manually removed from the hangar by hand. The beads were separated one by one and fed to the molding machine.

Therefore, there is a problem in that productivity is reduced in terms of time or cost because the process of loading, transporting and separating the finished beads is dependent on simple manual operation of the worker. Moreover, the process was more complicated and the productivity was lowered because the separator had to be inserted and hung to prevent the beads from sticking together.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a feed device for supplying tire beads for increasing productivity and simplifying work by automating loading, transporting, separating and supplying of beads to a molding machine.

Provided is a feed device for tire beads comprising a loading device and a cassette separating up-down device for vertically moving empty cassettes from which beads are separated to the lower conveying conveyor.

Here, the cassette has bead attachment plates to which permanent magnets are attached.

In addition, the bead attachment plates are arranged symmetrically with respect to the cassette center.

On the other hand, the automatic bead loading device, the loading arm is attached to the permanent magnet to attach the beads, the rotary drive means for rotating the loading arm attached to the bead to the loading position of the cassette, and the loading arm- It consists of a rotary cylinder which rotates in the range of 90 degrees-+90 degrees. That is, the loading arm reaches the loading position of the beads through the revolution, and is sandwiched between the bead attachment plates through the rotation.

In addition, one up-down device is provided at each of both ends of the conveyance direction of the upper and lower two-stage conveyor apparatus.

Here, the said conveyor apparatus is equipped with the roller chain for carrying and conveying the said cassette.

In addition, the conveyor apparatus includes a turntable provided during the conveying direction of the roller chain to rotate the cassette 180 ° about a vertical axis, a stopper for temporarily storing the cassette arriving at the turntable, and a cassette stopped by the stopper. It consists of an up-down cylinder that moves up and down to separate it from the roller chain.

In addition, the automatic bead unloading device is composed of two unloading arms with permanent magnets, and the two can rotate 180 ° about the hinge axis from the cassette to the molding machine at the same time.

Here, the loading arm or the unloading arm is configured to be able to load or detach the beads while passing through the bead attachment plate installed in a row in the cassette.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

Fig. 1 shows the overall feeding and feeding device for tire beads according to the present invention. When the empty cassette 300 enters the cassette stacking up-down apparatus 200 from the lower conveyor 402 of the cassette conveying conveyors of the upper and lower two stages, the cassette 300 is connected to the stacking up-down apparatus 200. It will be at the bottom dead center, and accurate centering needs to be made for the beads 1 to be loaded properly. In this state, the bead loading device 100 automatically attaches the manufactured flat bead 1 to the loading arm 102 and automatically to the cassette 300 installed at the bottom dead center of the cassette loading up-down device 200. I load it.

When the loading is completed, the cassette loading up-down apparatus 200 raises the cassette 300 to the upper conveyor apparatus 401. Thereafter, the cassette loading up-down apparatus 200 is lowered back to its original position (lower dead center).

The cassette 300 arriving at the upper conveyor 401 is moved by a side roller chain 405 driven by a motor or the like. During the movement, the cassette 300 is rotated by 180 ° by the turntable 412 so as to face the direction in which the beads 1 are easily separated. In this state, the cassette 300 is transferred toward a molding machine (not shown). When the cassette 300 loaded with the beads 1 reaches the cassette separating up-down apparatus 500 located near the end of the upper conveyor 401, the cassette 300 is temporarily waited to be separated smoothly. ) Centered again. Next, the bead 1 is fed from the cassette 300 toward the molding machine by the bead unloading device 600. The separating up-down device 500 remains in standby at that position (top dead center) until the bead 1 is completely detached from the cassette 300.

When the beads 1 are completely separated, only the empty cassette 300 remains, which is lowered to the lower conveyor 402 by the cassette separating up-down apparatus 500. Subsequently, the empty cassette 300 is moved by the conveyor 402 to reach the cassette loading up-down apparatus 200. Therefore, the bead 1 is loaded on the cassette 300 again, and the circulation process is performed by the cassette loading up-down apparatus 200.

Hereinafter, each of the above components will be described in more detail.

2 shows an automatic bead loading device 100 according to an embodiment of the present invention. The planar beads 1 conveyed by the bead conveying means (or "conveyor") 3 are loaded into the cassette 300 by a bead loading arm 102 (see FIGS. 1 and 3). ). Since the permanent magnet 4 is attached to this loading arm 102, and the wire is planted in the bead 1, it can adhere strongly to each other when approaching. The beads 1 conveyed by the conveyor 3 are attached to the loading arm 102 in this way, and are rotated from the <1> position to the <2> position by the motor 105 to which the reducer is attached. However, since the installation direction of the cassette 300 (see Fig. 1) at the <2> position is perpendicular to the surface direction of the bead 1 at the <1> position, it is from the <1> position to the <2> position. When moved, it is necessary to rotate the loading arm 102 by ± 90 °. Of course, when you return from the <2> position to the <1> position, it works in the reverse order. Here, the rotation direction (± 90 °) of the rotary cylinder 104 for rotating the rotating shaft of the loading arm 102, as shown in Figure 3, the bead attachment plate (symmetrically disposed with respect to the cassette center (CC) ( It is determined depending on which of the beads 301 is to be loaded.

3 and 4 illustrate a cassette 300 which is a delivery port of beads using permanent magnets. As shown in the figure, it can be seen that the bead 1 is loaded on the cassette 300 by the automatic bead loading device 100. The cassette 300 is provided with a bead attachment plate 301 to which the permanent magnet 4 is attached so that the beads 1 can be attached. In the present exemplary embodiment, since 16 beads 1 may be attached to one cassette 300, 16 bead attachment plates 301 are required. As shown in FIG. 3 (c), since the beads must be formed on both sides of the tire in the axial direction, the bead attachment plates 301 need to be formed symmetrically with respect to the center line C-C. Permanent magnet 4 attached to the bead attachment plate 301 is preferably to be able to appropriately adjust the length to correspond to the size change of the bead (1). Then, a magnetic force and a quantity strong enough to prevent the bead 1 from falling during movement are required.

4 is a diagram illustrating a process in which the cassette 300 with the beads 1 inserted therein and the loading arm 102 transfer the beads 1 to the bead attachment plate 301 of the cassette 300. In the center of the cassette 300, the left side shows the state in which the beads 1 are inserted, and the right side shows the state in which the loading arm 102 moves to load the beads 1 before the beads 1 are inserted. First, the beads 1 are attached to one side of the loading arm 102 to enter between the attachment plates 301, which are attached to the opposite side of the bead attachment plate 301 to which the beads 1 are to be attached. In addition, the loading arm 102 is formed with a groove 103 large enough to pass through the attachment plate 301 so that the loading arm 102 is attached to the bead 1 at the position <B>. The bead 1 attaches to the attachment plate 301 and the loading arm 102 passes through the attachment plate 301 as it is moved to the position. Such a linear motion is made by the motor 106 of FIG. 2, the ball screw 107 for converting the rotational motion into a linear motion, and a guide 108 for guiding the linear motion. Here, the motor 106 and the ball screw portion 107 are preferably selected to be connected by a timing belt and capable of precise position control. In addition, from <B> position to <1> position (refer FIG. 2) is made by the rotational motion by the motor 105 (refer FIG. 2), and another bead 1 is attached.

5 shows an up-down apparatus for stacking cassettes. The stacking up-down device 200 accepts the empty cassette 300 at the bottom dead center, and appropriately aligns the left and right centers of the cassette 300 so that the bead loading device 100 can stably load the beads 1. Play a role. When the loading is completed as shown in FIG. 3, the cassette 300 is raised to the position of the upper transfer conveyor 401. Here, reference numeral 201 denotes a frame for supporting the cassette up-down apparatus (see FIG. 5A). Then, when the cassette 300 enters the cassette up-down apparatus 200 in the direction of the arrow, a driving roller 204 and a general roller are installed to smoothly move the cassette 300. The vertical movement of the cassette 300 is made by two cylinders 202 and guided and supported by the guide shaft 203. In addition, stoppers 208 and 209 are used for accurate positioning of the top dead center and the bottom dead center when the cassette 300 is moved up and down.

The center of the cassette 300 is aligned by the cylinder 206 and the cassette support device 207. This is accomplished by the cylinder 206 pushing the cassette 300 entering the cassette up-down apparatus 200 into the cassette support 207.

6 shows a conveyor apparatus 400 for moving the cassette 300 to a predetermined position. This moves the cassette 300 on which the beads 1 are loaded to a tire molding machine (not shown) to use the beads 1 for tire production, and to load the beads into the empty cassette 300 again. It serves to move to (200). The conveying conveyor 400 may be changed in length depending on the distance between the bead loading device 200 and the molding machine, it is also possible to pause the cassette 300 on the conveyor.

The conveyor has a two-stage structure. The upper conveyor 401 has a structure in which the cassette 300 loaded with the beads 1 moves, and the lower conveyor 402 moves the empty cassette 300. The side roller chain 405 may use a normal roller chain, and is driven by the motors 404 and 403 arranged at the upper and lower ends, respectively. The side roller chains 405 are arranged in two rows side by side in the axial direction of the roller for stable movement of the cassette. The roller chain 405 is a structure in which the rollers are installed on both sides of the general chain, the cassette 300 is carried on the roller, and if the movement of the cassette 300 is blocked, the roller is attached to the cassette 300 As the slide (rolling) proceeds normally, the pause function of the cassette 300 may be performed. Theoretically, since the lower side of the roller of the side roller chain 405 touches the support and the upper side touches the cassette surface, the moving speed of the cassette 300 is doubled as the chain moving speed. In order to prevent this and move more stably and to reduce the wear of the rollers, the support plate was placed at the bottom of the bushing between the chain links so that the rollers were spaced apart from the support parts so that the rollers and the support parts could be separated from each other.

As described above, a stopper 410 is provided to temporarily block the progress of the cassette 300. The stopper 410 has a structure of a cylinder 409 and a link 411. When it is necessary to prevent the cassette 300 from advancing, the stopper 410 expands the cylinder 409 to raise the link 411 upwards and a roller. If only the progress of the cassette is necessary, the cylinder 409 is contracted, and when the link 411 is lowered down, the cassette 300 is loaded on the roller to proceed together.

In addition, since the bead loading direction and the unloading direction of the cassette 300 are opposite, it is necessary to turn the cassette direction. To this end, cassette turntables 412 are provided in the middle of the upper and lower cassette transfer conveyors 401 and 402, respectively. The turntable 412 is disposed between two rows of side roller chains 405. In the upper conveyor 401, when the cassette 300 arrives at the turntable 412, the stopper 410 moves to the cassette 300. Is stopped once and the up-down cylinder 407 raises this cassette 300 so as to be separated from the side roller chain 405, and is rotated 180 degrees by the rotating cylinder 406. FIG. Next, the up-down cylinder 407 is lowered again so that the cassette 300 is loaded on the side roller chain 405 and the stopper 410 is lowered to continue the cassette 300. In addition, a support ball (not shown) is installed under the turntable 412 to allow smooth rotation. The turntable 412 is similarly provided to the lower conveyor 402 so that the empty cassette 300 can be rotated 180 degrees.

The side roller chain 405 is in two rows, and power is transmitted by two sprockets 413 fixed to one shaft 414.

Meanwhile, the cassette separating up-down apparatus 500 of FIG. 1 is a structure for moving the empty cassette 300 to the bottom dead center after supplying the beads 1 from the cassette 300 toward the molding machine. Since the function is the same as the down device 200, detailed description thereof will be omitted.

7 shows a bead unloading apparatus for removing the beads 1 in the cassette 300 and supplying them to the molding machine. Since two beads are used to manufacture a tire, two beads are simultaneously removed from the cassette 300 and supplied to a molding machine. The principle of removing the beads 1 from the cassette 300 is the reverse of the method for loading the beads in FIGS. 2 and 4 above. This will be described in detail below.

When the unloading arm 601 moves past the bead attachment plate 301 while moving toward the center side CC of the cassette 300, the bead 1 is separated from the bead attachment plate 301 and the unloading arm 501 ) Is attached to the beads. In this state, when it rotates 180 degrees with respect to the hinge axis X as it is, the bead 1 can be supplied to a molding machine. At this time, the unloading arm 601 is formed in a shape in which the center is opened so as not to interfere with the bead attachment plate 301 of the cassette 300. In addition, the unloading arm 601 is also sized and determined so that the permanent magnet 4 can be used without replacement for each of the specifications of the bead 1. Since two beads 1 must be applied to one tire, two unloading arms 601 are required and need to be configured to simultaneously flip about the X axis (parallel axis). To this end, the ball screw portions 611 and 612 to which the unloading arm 601 is installed are formed of one left screw and the other right screw, and are preferably coupled and fixed to each other by the coupling 608. Therefore, when the ball screw portions 611 and 612 are operated by the timing pulley 606 and the belt 607 of the motor 605 installed below the unloading arm 601, the two unloading arms 601 The linear movement of expansion / contraction is simultaneously performed along the ball screw portions 611 and 612 and the LM guide 603. Here, the motor 605 for driving the ball screw portion should be capable of accurate position control as well as the motor 106 used in the bead loading device 100.

On the other hand, the 180 ° rotation from the cassette 300 side of the unloading arm 601 toward the molding machine is made by the reduction motor 604 provided in each of the unloading arms 601. The two unloading arms 601 rotated toward the molding machine are divided into two unloading arms 601 by the motor 605 rotating the ball screw portions 611 and 612 when the molding machine catches the beads 1. In this case, the beads 1 are forcibly separated from the unloading arm 601 and smoothly supplied to the molding machine.

Here, the unloading arm 601 supplied with the bead 1 to the molding machine primarily removes the bead 1 from the bead attachment plate 301 of the cassette 300 while maintaining the vertical state by rotating only 90 °. After the linear movement to the position is rotated again by 90 ° to separate the beads from the cassette (300). And by rotating 180 degrees in reverse, the operation | movement which supplies the bead 1 to a molding machine is repeated.

According to the present invention of the configuration as described above, there is an advantage that the productivity can be simplified and the operation can be simplified by automating the loading, transportation, separation and supply of the beads to the molding machine.
