Description

  The present invention relates to a balance weight parallel body in which balance weights of wheels for adjusting the unbalance in the circumferential direction and the axial direction of a wheel incorporating a tire for an automobile are arranged, and a manufacturing apparatus and a manufacturing method of the balance weight parallel body.

  Conventionally, a balance weight of a wheel in which a metal piece such as lead or iron is formed into a rectangular pellet shape by a press machine is known (see, for example, Patent Document 1). For example, as shown in FIG. 9, the balance weight W has a substantially trapezoidal shape when viewed from the side, and has a smooth arcuate surface with corners where the front surface, the rear surface, and the side surface and the upper surface are continuous. Is formed. A plurality of balance weights W are arranged on the strip-like release sheet (adhesive sheet) S so that the trapezoidal shape is continuous, and the bottoms of the trapezoidal shapes are arranged in line contact with each other. Various types of balance weights have been proposed in addition to the above, but in order to maximize the number of balance weights to be attached in the unit length of any balance weight, the release sheet (adhesive sheet) must be Lined up in contact.

  Therefore, the number of balance weights W attached in the unit length of the release sheet (adhesive sheet) S can be maximized. For example, as shown in FIG. 9, the balance weights W are formed in the same shape and the same size. For example, the material (for example, “Fe”) and the weight (for example, “5 grams”) are engraved on the upper surface. Has been. The plurality of balance weights are stuck on the strip-shaped release sheet S with an adhesive N interposed therebetween.

  Further, since the balance weight W has a trapezoidal shape when viewed from the side, for example, the front surface and the rear surface of the balance weight W form inclined surfaces that spread downward. Accordingly, not only the balance weight W but also other balance weights are similarly attached onto the strip-shaped release sheet (adhesive sheet) S via the adhesive N, and the release sheet (adhesive sheet) with the balance weight W on the inside. S can be wound in a spiral shape until the rear surface of one balance weight W interferes with the front surface of the other balance weight W adjacent thereto. Thereby, many balance weight W will comprise one cylindrical block body with the peeling sheet (adhesive sheet) S, and handling of the balance weight parallel body becomes easy.

  On the other hand, when the balance weight W is used, the release sheet (adhesive sheet) S of the cylindrical block body is rewound over a predetermined length, and at the tip of the rewound release sheet (adhesive sheet) S. A necessary number of balance weights W are separated (separated) from the object and attached to the rim R of the wheel H to be measured as shown in FIG. Thereby, the balance adjustment work of the wheel H can be performed very easily and quickly without damaging the rim R.

JP 2009-174712 A

  However, in such a conventional balance weight parallel body, even if the shape of the thickness portion of the balance weight W attached to the release sheet S is substantially trapezoidal as described above, the bottom of adjacent balance weights W As shown in FIG. 8, when the release sheet S is wound in a spiral shape with each balance weight W on the inner side as shown in FIG. 8, the rear surface of one adjacent balance weight W and the other The balance weight W immediately interferes with the front surface of the balance weight W. For this reason, the winding diameter with respect to the number of the balance weights W on the release sheet (adhesive sheet) S, that is, the outer diameter of the entire cylindrical block body becomes larger than necessary, which is inconvenient for transporting and storing the cylindrical block body. There was inconvenience that it was.

  The present invention solves the above-mentioned conventional problems, and the object of the present invention is to provide a pressure-sensitive adhesive sheet by arranging a plurality of balance weights in parallel at regular intervals on a belt-shaped pressure-sensitive adhesive sheet. The outer diameter of the cylindrical block body wound around the wheel can be made sufficiently small, which makes it easier to handle, transport, and store the cylindrical block body. An object is to provide a weight parallel body manufacturing apparatus and a manufacturing method.

In order to achieve the above object, an apparatus for manufacturing a balance weight parallel body according to claim 1 of the present invention comprises a balance weight accommodating portion for accommodating at least a plurality of balance weights,
A balance weight supply passage through which the balance weights positioned at the front and rear of the balance weight storage portion are continuously transferred in line contact with each other;
An adhesive sheet delivery section for delivering a strip-shaped adhesive sheet coated with an adhesive on one side;
A balance weight adhering portion having an arcuate support surface for adhering the balance weight sequentially delivered from the balance weight supply passage to the adhesive sheet delivered from the adhesive sheet delivery portion, and
The balance weight fed from the balance weight supply passage is fed from the adhesive sheet feeding section while generating a small interval of a predetermined width in the feeding direction between the balance weights positioned before and after the balance weight on the arcuate support surface. It is characterized in that the adhesive sheets are sequentially arranged and adhered.

According to a second aspect of the present invention, there is provided a balance weight parallel body manufacturing method using the balance weight parallel body manufacturing apparatus according to the first aspect, wherein a balance weight fed from a balance weight housing portion is fed to a balance weight supply passage. The balance weights positioned in front and back in the delivery direction are in line contact with each other and transferred continuously,
On the other hand, a belt-like adhesive sheet coated with an adhesive on one side is sent out from the adhesive sheet delivery part, and the balance weight sent out from the balance weight supply passage is sequentially guided onto the arcuate support surface of the balance weight attaching part, The pressure-sensitive adhesive sheet fed from the pressure-sensitive adhesive sheet feed-out portion is adhered to the pressure-sensitive adhesive sheet through a pressure-sensitive adhesive while generating a small gap having a predetermined width between the guided balance weights.

  As a result, when each adjacent balance weight and adhesive sheet are attached at the balance weight attaching portion, the adhering is performed on the arcuate support surface, so that the adjoining balance weights are separated from each other. A certain small interval can be generated. In other words, when the adjacent preceding balance weight reaches the arc-shaped support surface, the arc-shaped support surface is inclined with respect to the immediately following balance weight by the arc-shaped support surface, and therefore, between the preceding balance weight and the immediately following balance weight. A V-shaped opening (gap) is generated on one end side, and in this state the adhesive is attached to the adhesive sheet on the side where the opening has occurred. Therefore, a balance weight is attached to the adhesive sheet with a small gap. Is done. For this reason, the strip-shaped balance weight parallel body obtained by sticking has a rear surface of one balance weight adjacent to each other on the pressure-sensitive adhesive sheet when it is wound into a spiral block with the balance weight inside. And the front surface of the other balance weight interfere with each other, the pressure-sensitive adhesive sheet bends at a large angle or inclination at a site where these balance weights are adjacent. For this reason, the spiral diameter can be reduced particularly in the vicinity of the central portion of the cylindrical block body, and as a result, the outer diameter of the entire cylindrical block body can be suppressed to be small.

  In the balance weight parallel body according to claim 3 of the present invention, the balance weights are adhered in a line on the belt-like pressure-sensitive adhesive sheet with a predetermined small interval between the balance weights located at the front and back. It is characterized by.

  With this configuration, the small distance between the front surface of one adjacent balance weight and the rear surface of the other balance weight is the winding diameter when the pressure-sensitive adhesive sheet provided with these balance weights is spirally wound with the balance weight inside. In particular, the winding diameter in the vicinity of the center portion of the cylindrical block body can be reduced, and as a result, the outer diameter of the entire cylindrical block body can be kept small. For this reason, the number of balance weights installed per unit length of the adhesive sheet is small, but the interval is small, so the number of reductions is not so large, and the number of balance weights installed as a whole for the cylindrical block body with a predetermined diameter is sufficiently secured The outer diameter can be kept small, and as a result, handling, transportation, and storage of the cylindrical block body can be facilitated.

According to the present invention, it is possible to reduce the outer diameter and reduce the weight of the cylindrical block body around which the balance weight parallel body is wound while facilitating each operation of handling, transporting and storing the balance weight parallel body. .

Hereinafter, a balance weight parallel body and an apparatus for manufacturing the balance weight parallel body according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the balance weight parallel body manufacturing apparatus according to the present embodiment includes a balance weight storage portion A, balance weight transfer passages B and C, an adhesive sheet delivery portion D, and a balance weight attachment portion E. And an adhesive sheet take-up portion F. The balance weight accommodating part A and the balance weight transfer passage B are attached to a frame 12 with casters 11. Further, the balance weight transfer passage C, the adhesive sheet delivery part D, the balance weight sticking part E and the adhesive sheet take-up part F are attached to a frame 14 with casters 13. The frame 12 and the frame 14 constitute a machine frame of the manufacturing apparatus.

  The balance weight accommodating portion A includes a hopper 15 that accommodates a large number of rectangular pellet-shaped balance weights W that have been pre-shaped to a predetermined shape and size, and a large number of the balance weights W that are introduced from the upper opening are disposed in the lower layer. It functions so as to continuously send out from a certain outlet sequentially from the lower outlet. The hopper 15 may be provided with a short (not shown) to guide the balance weight W delivered from the delivery port. The balance weight W may be sent out by gravity, or a sending device using power (not shown) may be used. As shown in FIG. 6, the balance weight W in this example has a trapezoidal shape when viewed from the side, and the front surface t1 and the rear surface t2 face downward from each other (in the direction from the top surface to the bottom surface). Although it is an inclined surface that spreads out, it is not limited to this.

  The balance weight transfer passage B is stretched between the drive pulley 16 and the driven pulley 17 and includes a belt conveyor 19 driven by a motor 18. The balance weight W sent from the balance weight storage portion A is transferred to the belt conveyor 19. It functions so as to be sent to the lower side in order. In this way, the plurality of balance weights W sent in order from the delivery port are sent to the balance weight supply passage C which is continuous by the belt conveyor 19. The belt conveyor 19 may be configured such that the belt conveyor 19 is omitted, the transfer path is inclined, and the belt conveyor 19 is moved by gravity by the inclination.

  The balance weight transfer passage C is stretched between the drive pulley 20 and the driven pulley 21 and includes a belt conveyor 23 driven by a motor 22. The balance weight transfer passage C sends the balance weight W sent out from the balance weight transfer passage B in the delivery direction ( (Feed direction). The speed of the belt conveyor 23 is arbitrarily set by a drive control device (not shown) of the motor 22 that drives the belt conveyor 23. The balance weight transfer passage C is a weight supply passage 44 that is inclined following the belt conveyor 23. A protective cover 45 as shown in FIG. 3 is provided above the weight supply passage 44. Facing the exit of the weight supply passage 44, an arcuate support surface 41a of a balance weight sticking portion E described later is provided supported by the weight support base 41. Since the balance weight supply passage 44 is inclined, the balance weight W moves downward in the inclination due to gravity and comes into contact with the balance weight W positioned immediately before, so that the balance weights W on the front and rear sides are in line contact with each other. Move in an aligned state.

  The pressure-sensitive adhesive sheet delivery part D is formed by winding a pressure-sensitive adhesive sheet 24 having a pressure-sensitive adhesive N applied to one side of a strip-shaped release sheet S around a reel (or spool) 25 in a roll shape. The sticking sheet sending part D functions to send the adhesive sheet 24 continuously or intermittently at a predetermined speed by the motor 26. Here, in order to make the feeding of the adhesive sheet 24 by the motor 26 smooth, a tension applying device 27 for applying a constant tension to the adhesive sheet 24 and an adhesive sheet 24 to be described later are provided on the travel path of the adhesive sheet 24. A plurality of guide rolls 28 and the like for guiding toward the balance weight attaching portion E are provided. The delivery speed and delivery timing of the adhesive sheet 24 can be arbitrarily set by a drive control unit (not shown) of the motor 26.

  As shown in FIGS. 2 and 3, the balance weight adhering portion E functions to press-contact the balance weight W and the pressure-sensitive adhesive sheet 24 via the pressure-sensitive adhesive, and supports the pressure-contact roll 29 and the weight support that are opposed to each other. An arcuate support surface 41 a supported by the base 41 is provided. In this balance weight sticking part E, the balance weight W sent out from the balance weight supply passage 44 of the balance weight transfer passage C is attached to the pressure sensitive adhesive sheet 24 sent out from the pressure sensitive adhesive sheet sending part D via the pressure sensitive adhesive. Put on. Here, the plurality of balance weights W are stuck on the adhesive sheet 24 sent out at a predetermined speed via an adhesive in an aligned state with a constant small interval G as shown in FIG.

  In this case, successive balance weights W fed out from the balance weight transfer passage C are sequentially guided onto the arc-shaped support surface 41a of the weight support base 41, so that they are adjacent to each other in the traveling direction on the arc-shaped support surface 41a. A small gap G having a predetermined width is generated between the balance weights W, and is adhered to the adhesive sheet 24 in that state. That is, as schematically shown in FIG. 5, when the preceding balance weight W1 sent from the balance weight supply passage 44 reaches the arcuate support surface 41a, the balance weight W1 is continuous with the arcuate support surface 41a. Since it is inclined with respect to the balance weight W2 immediately after the opening, an opening G is generated on one end side between the balance weight W1 on the preceding arcuate support surface 41a and the balance weight W2 immediately after the balance weight W1, and the opening is performed in this state. Since this is continuously performed on the pressure-sensitive adhesive sheet 24 on the side where G is generated, a balance weight is continuously adhered to the pressure-sensitive adhesive sheet 24 with a small gap G and arranged. This small gap G is sufficient to prevent the pressure-sensitive adhesive sheet 24 from adhering to each other before the adjacent balance weights W interfere with each other when the pressure-sensitive adhesive sheet 24 with the balance weight W attached is wound in a spiral shape as shown in FIG. It is sized so that it can be bent. Thereby, the winding diameter of the adhesive sheet 24, especially the winding diameter of the center part of the cylindrical block body P can be made small. As a result, the outer diameter of the entire cylindrical block body P can be reduced.

  The pressure contact roll 29 is driven via an endless belt 32 by a motor 31 mounted on a motor support base 30. Further, the motor support 30 is installed on the base 33 so as to be able to rotate (tilt) via the pivotal support 34 and is linear along the guide member 38. A hydraulic cylinder 35 is installed on the base 33, and the distal end portion of the telescopic rod 36 of the hydraulic cylinder 35 is pivotally supported by one end of an L-shaped link 37 attached to the side surface of the motor support base 30. . Accordingly, the reciprocating operation of the telescopic rod 36 of the hydraulic cylinder 35 enables the motor support 30 provided with the pressure roller 29 to be rotated around the pivotal support 34, and as shown in FIG. Can be evacuated. As a result, replacement and maintenance of the press contact roll 29 can be executed as needed.

  Further, a "<"-shaped support member 42 is attached in the vicinity of the position where the press contact roll 29 of the motor support base 30 is installed, and the weight support base 42 is attached to the end of the support member 42 from the balance weight alignment portion C. A guide rail 43 that guides the travel of the adhesive sheet 24 while being in contact with the upper surface of the balance weight W that is sent out via the arcuate support surface 41a of 41 is rotatably provided.

  A motor 26 for driving the motor 22 and the reel 25 in the balance weight transfer passage C can arbitrarily adjust the speeds of the belt conveyor 23 and the reel 25, respectively. Therefore, in this embodiment, the feeding (rewinding) speed of the adhesive sheet 24 wound around the reel 25 can be adjusted with respect to the feeding speed of the balance weight W by the belt conveyor 23. That is, the balance weight W can be sent out onto the adhesive sheet 24 at a predetermined speed by controlling the rotation speed of the motors 22 and 26 according to a procedure programmed in advance. Then, the balance weight W is arranged adjacent to and pasted on the adhesive sheet 24 so as to maintain the necessary small gap G on the arc-shaped support surface 41 a of the weight support base 41.

  As a result, the number of balance weights W per unit length of the pressure-sensitive adhesive sheet 24 is reduced, but since the interval G is small, the number of reduction is not so great, and the outer diameter of the entire cylindrical block P having a predetermined diameter is reduced. As a result, handling, transportation, and storage of the cylindrical block P can be facilitated. The pressure-sensitive adhesive sheet take-up unit F functions to wind up the pressure-sensitive adhesive sheet 24 to which the balance weight W is adhered to the reel 40 driven by the motor 39, and has the balance weight W wound up here. The winding diameter of the central part of the cylindrical block body P of the pressure-sensitive adhesive sheet 24 can be minimized.

  Next, the operation of the balance weight parallel body manufacturing apparatus will be described. In this example, as shown in FIG. 6, the balance weight W has a trapezoidal shape when viewed from the side, and the front surface t1 and the rear surface t2 are inclined so as to spread downward. A plurality of balance weights W in this form are put into the hopper 15 of the balance weight accommodating part A. The balance weight W in the hopper 15 is sequentially sent out of the hopper 15 from the bottom of the hopper 15 by its own weight or using a swing imparting means or vibration imparting means (not shown).

  Subsequently, the balance weight W sent from the hopper 15 is placed on the belt conveyor 19 in the balance weight transfer passage B, and is sent out obliquely downward. The balance weight W on the belt conveyor 19 is transferred to the balance weight transfer passage C.

  Subsequently, the balance weight supply passage 44 of the balance weight transfer passage C is inclined, and the balance weight W moves downward in the inclination due to gravity and comes into contact with the balance weight W located in front. The balance weight moves in line with line contact. The balance weights W are successively sent out from the balance weight supply passage 44 to the balance weight attaching portion E, and the balance weights W are guided onto the arcuate support surface 41a of the weight support base 41. On the arcuate support surface 41a, a small gap G having a predetermined width is generated between the balance weights W adjacent in the traveling direction as shown in FIG. The small gap G is generated by moving on the arcuate support surface 41a. This is done by installing a sensor, a balance weight position adjusting means (not shown) in the vicinity of the weight support base 41, and setting the small gap G. It may be implemented by controlling and monitoring.

  On the other hand, an adhesive sheet 24 in which an adhesive is applied on one side in advance is wound around the reel 25 so that the adhesive is on the inside. One end of the pressure-sensitive adhesive sheet 24 wound around the reel reaches a portion facing the arcuate support surface 41a through a tension applying device 27, a guide rail 28, and a pressure roll 29 constituting a balance weight attaching portion E in order. Furthermore, it can be wound on a reel 40 constituting the adhesive sheet winding portion F. The adhesive sheet 24 is wound on the reel 40 by the power of the motor 29.

  Therefore, when the pressure-sensitive adhesive sheet 24 is guided by the pressure roller 29, the bottom surface of the balance weight W that is supported by the pressure-sensitive adhesive of the pressure-sensitive adhesive sheet 24 on the arc-shaped support surface 41a of the weight support base 41 and generates a small gap G. Is pressed. For this reason, on the adhesive of the adhesive sheet 24, the balance weight W is stuck one after another while maintaining the small gap G, and passes through the guide roll 43 at the end of the support member 42 to wind the adhesive sheet. The reel 40 of the take-up part F is wound up one after another.

  Here, the tension applying device 27 is connected to the reel 40 by the unstable operation of the running system in the motors 25 and 39 and the balance weight attaching part E when the adhesive sheet 24 fed out (rewinded) from the reel 25 is moved. Tension is applied to the pressure-sensitive adhesive sheet 24 so as to prevent loosening. Thereby, the balance weight W which continues on the adhesive sheet 24 in the balance weight sticking part E can be stuck in the alignment state which maintained the small space | interval G. Further, the motor support base 30 is rotatable around the pivotal support portion 34. For work such as maintenance of the balance weight attaching portion E and replacement of parts, the motor support base 30 is located at a position indicated by a two-dot chain line as shown in FIG. What is necessary is just to evacuate.

  As described above, the motors 22 and 26 can arbitrarily adjust the speeds of the belt conveyor 23 and the reel 25, respectively. Therefore, by adjusting the feeding speed (rewinding speed) of the pressure-sensitive adhesive sheet 24 wound around the reel 25 with respect to the feeding speed of the balance weight W by the belt conveyor 23, the continuous balance weight W is converted into the arc-shaped support surface. A predetermined small interval G can be generated on 41a and pasted. The rotational speeds of these motors 22 and 26 are driven and controlled by a control device (computer) according to a preprogrammed procedure.

  Accordingly, the number of the balance weights W per unit length of the pressure-sensitive adhesive sheet 24 is reduced by sticking the balance weight W while maintaining the small gap G as described above, but the small gap G is small. The number of reductions is not so great, and the overall outer diameter of the cylindrical block body P as shown in FIG. 8 can be kept small. As a result, the cylindrical block body P can be easily handled, transported, and stored. Can be Further, the adhesive sheet take-up unit F functions to take up the adhesive sheet 24 to which the balance weight W is adhered onto the reel 40 driven by the motor 39. The winding diameter of the central part of the cylindrical block body P of the pressure-sensitive adhesive sheet 24 having the balance weight W wound up here can be minimized to the above-described reason as shown in FIG.

  Then, the necessary number of balance weights W are peeled off together with the adhesive N from the release sheet S of the balance weight parallel body constituting the cylindrical block body P, and the adhesive N is passed through the wheel H as shown in FIG. By sticking, wheel balancing work can be carried out easily and quickly.

  As described above, according to the present embodiment, a plurality of balance weights W sent from the balance weight accommodating part A are sequentially sent out by the balance weight transfer passages B and C, and the balance weights W thus sent are sent to the balance weights. The balance weights positioned at the front and rear in the supply passage 44 are sent out in line contact, while the belt-like adhesive sheet 24 coated with an adhesive on one side is sent out from the adhesive sheet delivery part D and sent out from the balance weight supply passage 44. The balance weight W is sequentially guided onto the arcuate support surface 41a of the balance weight attaching portion E, and the adhesive sheet is fed while generating a small gap G of a predetermined width between the balance weights W in the guide direction. The pressure-sensitive adhesive sheet 24 sent out from the part D is pasted through the pressure-sensitive adhesive, DOO W is was decided to wound the adhesive sheet 24 adhered to the adhesive sheet take-up unit F. Thereby, as shown in FIG. 8, the outer diameter of the cylindrical block P around which the pressure-sensitive adhesive sheet 24 is wound with the balance weight W on the inside can be sufficiently reduced, and the weight is reduced by the decrease in the number of sticking per unit length. By reducing this, it is possible to obtain an effect that the balance weight parallel body can be easily handled, transported, and stored.

  In addition, according to the present embodiment, a plurality of rectangular pellet-shaped balance weights W are adhered to the belt-like pressure-sensitive adhesive sheet 24 at least in a line at a predetermined interval, and the pressure-sensitive adhesive sheet 24 provided with the balance weights W is illustrated in FIG. As shown in FIG. 8, the winding diameter when wound in a spiral shape with the balance weight W inside, particularly the winding diameter of the central portion of the cylindrical block body P, can be reduced. The outer diameter of can be kept small. For this reason, although the number of the balance weights W per unit length of the pressure-sensitive adhesive sheet 24 is reduced, the weight and outer diameter of the entire cylindrical block P having a predetermined diameter can be suppressed to a small value. Handling, transportation, and storage of the cylindrical block body can be facilitated.

  The present invention has an effect that it is possible to reduce the outer diameter and reduce the weight of the cylindrical block body around which the balance weight parallel body is wound while facilitating each work of handling, transporting and storing the balance weight parallel body. Further, it is useful for a balance weight parallel body of wheels, a manufacturing apparatus and a manufacturing method of the balance weight parallel body, and the like.
