Description

  The present invention relates to a tire bead wire removing device for extracting and removing a bead wire embedded in a rim of a waste tire.

  Conventionally, as a method for treating a waste tire, for example, a method of finely crushing into a chip shape is known. A bead wire in which a plurality of metal wires are twisted is embedded in the rim of the tire. For this reason, when the waste tire in which the bead wire is embedded is crushed, the crushing blade of the crushing device is quickly worn, and a problem of blade spilling occurs. For this reason, it was necessary to remove the bead wire from the waste tire in advance as a pretreatment for crushing into chips.

  Conventionally, various bead wire removing devices have been proposed as such bead wire removing devices. For example, Patent Documents 1 to 3 include a claw portion having a hook shape at the tip, and the claw portion is set so as to contact a portion of a bead wire embedded in a rim of a waste tire. There has been proposed an apparatus configured to pull out a bead wire from a waste tire by sliding the portion so as to be pulled inward.

  Since the bead wire removing device of Patent Documents 1 to 3 pulls the bead wire by hooking the claw portion of the pulling means on the bead wire while holding the waste tire on the panel, the pulling means is put in and out of the panel against which the waste tire is pressed. An opening is formed for this purpose. In Patent Document 1, this opening is constituted by a claw part and a large circular hole for inserting and removing the bead wire hooked by the claw part. In Patent Documents 2 and 3, the opening part is in a vertical direction in which the claw part is inserted and removed. It consists of a claw groove extending from the claw groove and a pair of left and right side grooves connected to the left and right sides of the claw groove. The claw part is drawn inward through the claw groove, and the bead wire hooked by the claw part is inserted from the left and right side grooves. It is configured to be drawn in.

  By the way, when pulling out a bead wire by hooking on a claw part embedded in the waste tire, the bead wire is drawn from a large-diameter hole as shown in Patent Document 1 because the waste tire is pulled around the bead wire. Since the waste tire attached to the periphery of the bead wire is drawn from the large-diameter hole, only the bead wire cannot be removed efficiently.

  In this regard, in Patent Documents 2 and 3, since the claw portion is drawn from the claw groove extending in the vertical direction and the bead wire hooked by the claw portion is drawn from the left and right side grooves, there is an excess waste tire attached to the bead wire. It is scraped off by the side groove and only the bead wire can be efficiently removed. However, scraped scraped tires will remain on the front side of the side grooves, so if the bead wire pulling process is repeated without removing scraped scraped tires, the scrap tires remaining on the front side of the side grooves will be removed from the bead wires. When the bead wire is pulled out, the bead wire is caught in the side groove when the bead wire is pulled out. For this reason, the conventional bead wire removing device requires maintenance such as removing the waste tires periodically scraped off, which has been a factor of deteriorating work efficiency.

  In view of the above problems, an object of the present invention is to provide a bead wire removing device that can effectively remove a bead wire remaining when the bead wire is pulled out and easily eliminate it.

The relationship between the lifting / lowering operation of the lift 6 and the tire bead pulling operation will be described later.

  At the position where the waste tire 1 is dropped in front of the input conveyor 2 (the left end in FIG. 1), there is provided a tire pressing means 9 that abuts and holds the waste tire 1 against the front panel 3A and the apparatus front plate 4. . The tire pressing means 9 includes a guide plate 15 and a tire pressing cylinder 16 which are disposed in an inclined manner so as to face the front panel 3A and the apparatus front plate 4, and the waste tire 1 dropped from the input conveyor 2 is first guided to the guide plate 15. And the guide plate 15 is slid in the direction of separating from the front panel 3A by the tire pressing cylinder 16, so that the waste tire 1 changes the direction of the lift lift 6 along the inclination in the standing direction. The guide shaft 15 is guided onto the support shafts 10, 10, and then the guide plate 15 is brought close to the front panel 3 </ b> A and the apparatus front plate 4 so as to press and hold the waste tire 1. As shown in FIG. 5A, the device front plate 4 is disposed facing the opening 3B formed in the front panel 3A so as to be flush with the front panel 3A when the tire bead is pulled out. Yes. The support shafts 10 are arranged in a direction orthogonal to the apparatus front plate 4 and the front panel 3A. Further, as shown in FIG. 1 and the like, the apparatus front plate 4 and the front panel 3A are arranged so as to be inclined by a receding angle β ° with respect to the vertical direction. In the present embodiment, the device front plate 4 and the front panel 3A are inclined by 5 ° as a receding angle with respect to the vertical direction, but are not necessarily limited to 5 °, and 2.5 ≦ β ≦ 30. It suffices to select appropriately within the range.

  As shown in FIGS. 1, 3, 4, and the like, the bead wire pulling means 5 includes a plate-like blade body 20, and a hook-like claw portion 21 provided so as to face downward at the lower end of the blade body 20. The wire pulling cylinder 22 serving as a pulling drive means for the blade body 20 and a pair of guide shafts 23 (FIG. 3) for slidably guiding the blade body 20, the blade body 20 is hooked on the bead wire 1 </ b> A for wire pulling. By sliding the blade body 20 by the cylinder 22 and drawing it, the bead wire 1 </ b> A embedded in the rim of the waste tire 1 is pulled out by the claw portion 21. As shown in FIGS. 1 and 4, the drawing direction of the bead wire 1A, that is, the drawing driving direction F of the wire drawing cylinder 22 is inclined with respect to the horizontal direction by an elevation angle α °. In this embodiment, the pulling drive direction F of the wire pulling cylinder 22 is inclined by 5 ° as an elevation angle with respect to the horizontal direction, but is not necessarily limited to 5 °, and 2.5 ≦ α ≦ 15. What is necessary is just to select suitably within the range. Further, the support shafts 10 and 10 extending in the direction orthogonal to the apparatus front plate 4 and the front panel 3A also have an elevation angle of α ° with respect to the horizontal direction in the same manner as the drawing driving direction F of the wire drawing cylinder 22 (this embodiment). In the example, it is inclined by 5 °), but this may be appropriately selected within the range of 2.5 ≦ α ≦ 15. As described above, in the present embodiment, the support shafts 10 and 10 are inclined at an elevation angle of 5 ° with respect to the horizontal direction, so that the center of gravity of the waste tire 1 supported by the support shafts 10 and 10 becomes the device front plate 4 side ( The waste tire 1 is tilted so as to be in close contact with the apparatus front plate 4 and the front panel 3A, and the waste tire 1 is abutted and supported by the apparatus front plate 4. .

  Further, as described above, the waste tire 1 supported by the apparatus front plate 4 is always inclined backward by inclining the apparatus front plate 4 and the front panel 3A by 5 ° as a receding angle with respect to the vertical direction. Since the urging force acts, the waste tire 1 is unlikely to fall forward when the waste tire 1 is moved up and down by the support shafts 10 and 10 or when the bead wire pulling means 5 is pulled out. Further, although not shown in the drawings, the provided waste tire 1 is further tilted toward the front panel 3A by providing the support shafts 10 and 10 of the lift 6 with a predetermined elevation angle with respect to the front panel 3A. You may comprise.

  Next, the drawing groove 30 formed in the apparatus front plate 4 will be described in detail mainly with reference to FIGS. As shown in FIG. 2, the drawing groove 30 includes a claw passage groove 31 extending in the vertical direction, and a pair of left and right side grooves 32, 32 provided on the left and right sides of the claw passage groove 31. The side grooves 32, 32 are formed to be inclined by about 30 ° so that the central part is lowered toward the claw passage groove 31. The claw passage groove 31 and the side grooves 32, 32 are a pair of left and right upper gate molds 40, 40, and a predetermined gap (corresponding to a gap corresponding to the width of the side groove 32) from the lower edge of the upper gate molds 40, 40. Are formed by a pair of left and right lower gate molds 41 and 41 arranged so as to be adjacent to each other. In this embodiment, the upper gate molds 40 and 40 and the lower gate molds 41 and 41 are configured to be flush with the apparatus front plate 4 when the bead wire is pulled out, and have a predetermined gap. A drawing groove 30 having the shape is formed. In other words, the pair of upper gate molds 40, 40 and the pair of lower gate molds 41, 41 are arranged at intervals in the left-right direction by the width of the claw passage groove 31, as shown in FIG. The upper gate molds 40, 40 are arranged at intervals in the vertical direction, and between the lower edges of the pair of upper gate molds 40, 40 and the upper edges of the pair of lower gate molds 41, 41 adjacent thereto. Side grooves 32 and 32 are formed, respectively.

  A claw passage groove closing bar 45 is disposed between the upper gate molds 40, 40. Although not described in detail, the claw passage groove closing bar 45 can be configured to slide in the vertical direction (the vertical slide mechanism is not shown), and the blade body 20 is hooked on the bead wire 1A to bead the wire. After the 1A is pulled out by the claw portion 21, the claw passage groove closing bar 45 can be slid to close the claw passage groove 31. As shown in FIG. 4, the pair of upper gate molds 40, 40 is pivotally supported by the horizontal shaft portions 46, 46 so as to be freely slidable. Thereby, the pair of upper gate molds 40, 40 are controlled by the cylinders 50, 50 so as to rotate around the shaft portions 46, 46 to open and close the side grooves 32, 32, respectively. That is, the bead wire 1 </ b> A pulled out from the waste tire 1 by the claw portion 21 of the blade body 20 passes through the side grooves 32, 32 and is pulled inward of the bead wire removing device. At this time, since the claw portion 21 is disposed downward, the bead wire 1A is detached from the claw portion 21 when the bead wire 1A comes out of the side grooves 32, 32, and the bead wire 1A falls on the discharge conveyor 25 by its own weight. The bead wire 1A is carried out by the discharge conveyor 25. At this time, since the drawing drive direction F of the drawing drive means of the bead wire drawing means is arranged to be inclined by an elevation angle α ° with respect to the horizontal direction, the bead wire 1A is further separated from the claw portion 21 inclined by α °. It has an easy configuration.

  The operation of the embodiment of the present invention configured as described above will be described. The waste tire 1 placed from the loading portion 2A of the input conveyor 2 is conveyed forward (left side in FIG. 1) and supplied from the front end portion of the input conveyor 2 to the lift lift 6. At this time, the support shafts 10 and 10 of the lift 6 are on standby in the vicinity of the highest position (preferably, a position slightly below the highest position), and the blade body 20 is pulled inward (right side in FIG. 1). Waiting at. Then, the waste tire 1 transferred to the front end portion (the left end in FIG. 1) of the input conveyor 2 falls from the input conveyor 2 and comes into contact with the guide plate 15 as a tire pressing means, and the guide plate 15 is moved to the front by the tire press cylinder 16. By sliding away from the panel 3A, the waste tire 1 is guided onto the support shafts 10 and 10 of the lift 6 while changing the direction in the standing direction.

  The support shafts 10 and 10 are inclined at an elevation angle of 5 ° with respect to the horizontal direction, and the waste tire 1 supported by the support shafts 10 and 10 moves to the rear side (that is, the right side in FIG. 1) with respect to the front panel 3A. And supported to tilt. Further, since the front panel 3A and the apparatus front plate 4 are inclined by 5 ° as a receding angle with respect to the vertical direction, the waste tire 1 supported by the support shafts 10, 10 and the apparatus front plate 4 and the front panel 3A is A biasing force that always tilts backward acts and is held in close contact with the apparatus front plate 4 and the front panel 3A.

  In this way, the lifting cylinder 13 is started in a state where the waste tire 1 is held on the apparatus front plate 4 and the front panel 3A, and the claw portion 21 is lowered by the lifting lift 6 to a standby position that enters the inner diameter of the waste tire 1. Next, the claw portion 21 is advanced by the wire drawing cylinder 22.

  At this time, since the claw portion 21 of the blade body 20 faces downward, in order to set the waste tire 1 at the bead extraction position, it is necessary to raise the lift 6 slightly. Thus, the waste tire 1 is set at the bead extraction position, and the side grooves 32 and 32 are formed by the pair of upper gate molds 40 and 40 and the pair of lower gate molds 41 and 41, and the blade body 20 is The bead wire 1A can be pulled out by protruding from the claw passage groove 31 formed by the retracted claw passage groove closing bar 45.

  At this time, for example, a sensor (not shown) may detect the inner edge of the waste tire 1 and stop the lifting lift 6 at a predetermined position so that the hooking state between the claw portion 21 and the tire is the best. Good. As a result, the waste tire 1 is accurately set at a position to be locked to the bead wire 1A embedded in the waste tire 1.

  Thereafter, when the claw portion 21 is retracted in the F direction by the wire pulling cylinder 22, the claw portion 21 bites into the rim portion of the waste tire 1 to tear the waste tire 1 and pulls it into the pulling groove 30. Only the bead wire 1A of the rim portion is hooked on the claw portion 21 and the bead extraction is started.

  When the claw portion 21 retracts in the claw passage groove 31 while pulling out the bead wire 1A in this way, the waste tire 1 is separated from the front panel 3A and the device front plate 4 (substantially a pair of upper gate molds 40, 40 and A pair of lower gate dies 41, 41) is supported and only the bead wire 1 </ b> A is pulled out through the pulling groove 30. At this time, the bead wire 1 </ b> A is guided by being fitted into the left and right pull-out grooves 32, 32, and is drawn to the rear side of the apparatus. In this way, the bead wire 1 </ b> A retracted while being guided by the claw passage groove 31 and the claw passage groove closing bar 45 in conjunction with the retraction operation of the claw portion 21, and the bead wire 1 </ b> A pulled out by the claw portion 21 does not enter the claw passage groove 31. The left and right drawing grooves 32, 32 are reliably guided. Since the bead wire 1A is buried in the entire rim portion of the tire, it is preferable to move the waste tire 1 downward sequentially by lowering the lifting lift 6 according to the degree of withdrawal of the bead wire 1A.

  Here, when the bead wire 1A embedded in the waste tire 1 is pulled out, the bead wire 1A is fitted around the pull-out grooves 32 and 32 with the waste tire 1 adhering to the periphery of the bead wire 1A, and is pulled in a state guided by the pull-out grooves 32 and 32. Therefore, the waste tire 1 attached to the bead wire 1A is scraped off into the drawing grooves 32 and 32, and after the bead wire 1A is pulled out, the waste tire 1 remains inside the front surfaces of the drawing grooves 32 and 32 and the drawing grooves 32 and 32. Sometimes. For this reason, there exists a possibility that the extraction grooves 32 and 32 may be blocked by the waste tire 1 remaining following the extraction operation of the bead wire 1A. However, in the embodiment of the present invention, the pair of upper gate molds 40, 40 are pivotally supported, and the upper gate molds 40, 40 are rotated by the cylinder 50 after the drawing process of the bead wire 1A. Thus, it is possible to employ a configuration in which the waste tire 1 remaining around the drawing grooves 32 and 32 is removed by widely opening the side grooves 32 and 32. The timing of the operation of sliding the upper gate molds 40, 40 for removing the remaining waste tire 1 is as follows: when the bead wire 1A is caught in the drawing groove 30, or one bead wire 1A removal cycle. Alternatively, the hydraulic cylinder 50 may be automatically driven to swing the upper gate molds 40 and 40 at a stage where the removal of the bead wire 1A is repeated a predetermined number of times.

  As described above, according to this embodiment, when the bead wire 1A is pulled out from the waste tire 1 by being hooked on the claw portion 21 by the bead wire 1A and removed, the bead wire 1A is fitted and guided in the left and right side grooves 32 and 32, and the rear Pulled into the side. At this time, since the waste tire 1 attached to the bead wire 1A is scraped off by the side grooves 32, 32, the waste tire 1 remaining on the front side of the draw grooves 32, 32 is removed while repeating the removal cycle of the bead wire 1A. Following the drawing operation of 1A, it enters into the side grooves 32, 32 and the like, and the drawing groove 30 is closed. However, in this embodiment, as shown in FIG. 5, the upper gate molds 40, 40 are pivotally supported, and the upper gate molds 40, 40 are swung back and forth by the hydraulic cylinder 50, so that the side groove 32. , 32 can be easily removed. Thereby, clogging of the drawing groove 30 can be prevented, and the drawing operation of the bead wire 1A can be performed smoothly. Further, maintenance work such as periodically removing the waste tire 1 can be omitted.

Hereinafter, a tire bead wire removing procedure using the tire bead wire removing device of the embodiment of the present invention will be described over time.
(1) The waste tire 1 is thrown in automatically or sequentially at the rear end (right end in FIG. 1) of the throwing conveyor 2.
(2) The waste tire 1 reaches the terminal end of the input conveyor 2 (the left end in FIG. 1) by the input conveyor 2 having an elevation angle θ and falls one by one from the terminal end of the input conveyor.
In this state, it is preferable to keep the apparatus front plate 4 composed of the upper gate mold 40 and the lower gate mold 41 flush with the frame 3, but the apparatus front plate 4 is flush with the frame 3. The timing to do can be selected by the timing until “6. Retract the claw portion 21 in the F direction by the wire drawing cylinder 22”.
(3) The waste tire 1 dropped one by one from the end of the input conveyor is held by the support shafts 10 and 10 of the lift lift 6 that stands by in the vicinity of the highest position (preferably, a position slightly below the highest position).
(4) In the state of (3) above, the blade body 20 with the claw portion 21 facing downward is inserted into the held opening portion of the waste tire 1.
(5) In order to hook the blade 20 on the bead wire 1 </ b> A of the waste tire 1 holding the downward claw portion 21, the lift 6 is slightly raised (the highest lift position of the lift 6).
(6) The claw portion 21 is moved backward in the F direction by the wire pulling cylinder 22.
(7) The claw portion 21 bites into the rim portion of the waste tire 1 and tears the waste tire 1 and pulls it into the pullout groove 30, and only the bead wire 1 </ b> A is caught in the claw portion 21 and the extraction of the bead is started.
(8) When the claw portion 21 retracts in the claw passage groove 31 while pulling out the bead wire 1A, the waste tire 1 is torn off by the upper gate molds 40, 40 and the lower gate molds 41, 41, and only the bead wire 1A is pulled out. It is pulled out from the waste tire 1 through the groove 30.
(9) The bead wire 1A is guided by being fitted into the left and right pull-out grooves 32, 32, and is drawn to the rear side of the apparatus. At this time, the lifting lift 6 is lowered according to the degree of pulling out the bead wire 1A, and the waste tire 1 is sequentially moved downward.
(10) At the end of the extraction of the bead wire 1A, the claw portion 21 of the blade body 20 is disposed downward, so that the bead wire 1A naturally falls on the wire discharge conveyor 25 from the blade body 20 drawn into the apparatus. And can be discharged out of the apparatus.
(11) Although the waste tire 1 from which the bead wire 1A has been pulled out is held on the lifting lift 6 at the lowest lowered position, it can be easily discharged automatically or manually and introduced into the waste tire crushing apparatus. It is possible to realize.
(13) At the timing when the bead wire 1A from the waste tire 1 is completely pulled out, the upper gate molds 40 and 40 are slid upward to open the side groove 32, thereby preventing the side wire 32 from being clogged with the bead wire 1A.

  As mentioned above, although the present Example was explained in full detail, this invention is not limited to the said Example, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the present embodiment, an example is shown in which the drawing drive direction F of the bead wire 1A is inclined by 5 ° as an elevation angle with respect to the horizontal direction. The bead wire 1A is separated, and the inclination of the bead wire 1A in the drawing drive direction F may be set in various ranges within a range of 2.5 ≦ α ≦ 15 in consideration of workability, apparatus layout, and the like. Similarly, the receding angle of the apparatus front plate 4 having the drawing groove 30 is set to 5 °, and the receding angle β may be set as appropriate within the range of 5 ≦ β ≦ 30. In the above embodiment, as shown in FIG. 5, the upper gate molds 40, 40 are pivotally supported so that the upper gate molds 40, 40 are swung by the hydraulic cylinder 50.
