Description

  The present invention relates to a method of assembling a tire for use in storing and transporting a tire by incorporating another tire inside one tire and an apparatus therefor.

When storing and transporting tires, it is preferable to accommodate as many tires as possible in the smallest possible space in order to reduce storage costs and transport costs.
Therefore, conventionally, a storage method, a storage device, and the like that can accommodate as many tires as possible in a small space have been proposed (see, for example, Patent Documents 1, 2, and 3).
Japanese Patent Laid-Open No. 11-106012 Japanese Patent Laid-Open No. 9-20408 JP-A-8-319006

However, since the technology described in the above-mentioned literature is to store individual tires in a standing or horizontal state, in order to store a larger number of tires in a limited space, a stack of tires is required. The number of stored items can be increased by about 20%, but a dramatic increase in the number of stored items exceeding this cannot be expected.
The present invention has been made in view of the above-described problems, and it is possible to store tires twice or more than conventional tires in the same space, and to incorporate tires that can drastically reduce storage costs and transportation costs. The object is to provide a method and apparatus therefor.

  In order to solve the above-described problem, the invention according to claim 1 is a method for assembling a tire in which another tire is inserted from a wheel mounting hole of one tire and the other tire is incorporated into the one tire. Two first proximity points are set at opposite positions on one side of the other tire, and two first adjacent points are set at opposite positions on the other side of the other tire in a direction orthogonal to the first adjacent point. Two adjacent points are set, and the other tires are bent so that each of the first adjacent points and each of the second adjacent points are close to each other, and the tread surface of the other tire is crossed when the other tires are bent. When the width dimension in the direction to be approximated to the hole diameter of the wheel mounting hole of the one tire, the other tire is inserted from the tread surface to the wheel mounting hole while maintaining a curved state. Type, said inside the foil mounting hole to expand the other tire while releasing the curved holding of the other tires, a method of incorporating the other tires in the interior of the one tire.

In this case, in order to curve the other tires so that each of the first proximity points and each of the second proximity points approach each other, the second tire corresponds to the first proximity point as described in claim 2. What is necessary is just to make it curve the said other tire by the same curved form as when pressing the other side surface of the said other tire and the one side surface of the said other tire corresponding to the said 2nd proximity point.
Moreover, in order to implement | achieve the curved form as described in Claim 1, while applying urging | biasing force in the direction which makes the said 1st proximity | contact point or said 2nd proximity | contact point approach mutually, as described in Claim 3 The urging force may be applied on an axis crossing the approaching direction.
Furthermore, as described in claim 4, at least in the final step of the bending, the tread surface may be inclined while applying a squeezing force in the vicinity of the boundary between the side surface of the other tire and the tread surface. .
By doing so, the entire width of the tire at the time of bending is reduced by the inclination of the tread surface, and the incorporation into one tire becomes easier.

The invention of the above-described method can be easily implemented by using the apparatus of claim 5 or below.
That is, the assembly device according to claim 5 is configured such that a pair of first hook devices engaged with the other tires in the vicinity of the second proximity point and a pair of the first hook devices approach each other at least. And a pair of hooks engaged with the periphery of the wheel mounting hole on an axis perpendicular to a straight line passing through the two second proximity points, and a pair of hooks. And a second hook device having a second driving means to be moved.

According to this configuration, the first hook devices engaged with the other tires in the vicinity of the second proximity point (including the same position as the second proximity point) are moved toward each other by the first driving means. While moving, the pair of hooks engaged with the peripheral edge of the wheel mounting hole is moved by driving the second driving means of the second hook device, so that each of the first proximity points and the second proximity point can be easily moved. Each of the proximity points can be brought closer together to curve the other tire.
Further, the first driving means may be capable of moving not only in the direction in which the first hook devices are brought closer to each other but also in the direction in which they are separated from each other. In this way, by moving the first hook means away from each other, it is possible to incorporate the other tire into the inside of one tire while forcibly deploying the other tire from the curved state.

  In this case, as described in claim 6, it is preferable to provide a tire standby portion for waiting the one tire. By doing so, the one tire can be engaged with the other tire from one or the other of the other curved tires, and the other tire can be easily incorporated into the one tire. .

  Further, when the hook hooking position is deviated from the orthogonal direction with respect to the first hook device, it is preferable to correct the hook position because a desired curved form cannot be obtained. The inventor has examined the shape of the hook in various ways, and found that the above-described shift can be easily corrected by making the hook a predetermined shape. That is, according to the seventh aspect of the present invention, the hook of the second hook device includes a hook portion on a distal end side that engages with a peripheral edge of the wheel mounting hole of the other tire, and the other tire. And a base-side bending portion that curves in a direction away from the base portion.

Moreover, as described in claim 8, the first hook device may have a swingable arm that engages with the other tire.
According to this configuration, the swingable arm can move the other tire by moving the first hook device in a direction in which the first hook device approaches each other with the tip of the arm engaged with the other tire. Curve. Further, the swingable arm tilts the tread surface while applying a squeezing force in the vicinity of the boundary between the side surface of the other tire and the tread surface at least in the final step of the bending. The overall width is reduced by tilting the tread surface, making it easier to incorporate into one tire.

In this case, as described in claim 9, a restricting means that contacts the arm and restricts swinging of the arm, and the restricting means when the pair of first hook devices approach a predetermined distance; It is good to comprise so that it may contact | abut and may have a press means which pushes each said arm in the direction which mutually approaches with a movement of said 1st hook apparatus.
According to this configuration, in the final stage of the step of bending the other tire, the swingable arm is forced to move the pair of first proximity points closer to each other by the movement of the pair of hook devices. It can be moved to finish the bending operation.
Moreover, although the said arm may be fixed to said 1st hook apparatus, as described in Claim 10, you may provide in a support body of said 1st hook apparatus so that attachment or detachment is possible.
In this manner, by removing the arm when the other tire is incorporated into the one tire, the arm does not get in the way and the operation can be performed more easily. Also, when the other hooks are forcibly deployed from the curved state by moving the first hook means away from each other, the arm does not get in the way and workability can be improved.

According to the present invention, it is possible to incorporate a tire into the tire, and it is possible to accommodate approximately twice or more conventional tires in the same space. In addition, it is possible to store a larger number of tires by combining with a conventional method such as devising a stacking form. Thus, according to the present invention, storage costs and transportation costs can be greatly reduced.
Further, according to the apparatus of the present invention, it becomes possible to automate the incorporation of another tire into one tire by the method of the present invention.

[Description of installation method]
Hereinafter, a preferred embodiment of the assembling method of the present invention will be described in detail with reference to FIGS.
FIG. 1 shows an embodiment of the method of the present invention, in which (a) is a schematic perspective view showing a state before the other tire 2 is assembled into one tire 1, and (b) is an inside of the tire 1. It is sectional drawing which shows the state which integrated the tire 2 into.
In the present invention, the tires 1 and 2 to be incorporated are obtained by removing the foil. The size of the tire 2 incorporated in the tire 1 may be the same size as that of the tire 1 because the tires 1 and 2 are flexible, but is preferably slightly smaller than the tire 1. In the illustrated example, two tires are incorporated. However, three or more tires may be incorporated sequentially.

For easy understanding of the method of the present invention, two first proximity points 2a and 2a are provided on one side surface (one side surface) 2e of the tire 2 to be incorporated on the same straight line passing through the center of the tire 2. The second side surface (other side surface) 2f is provided with two second proximity points 2b and 2b on a straight line passing through the center of the tire 2 and orthogonal to the straight line. These first proximity points 2a and 2a and second proximity points 2b and 2b are virtual points, and it is not necessary to physically provide a marking or the like.
The tire 2 is curved so that the first proximity points 2a and 2a and the second proximity points 2b and 2b set as described above approach each other.

FIG. 2A shows a state in which the tire 2 is curved by approaching the first proximity points 2a and 2a and the second proximity points 2b and 2b, and (i) in FIG. The front view of the curved tire 2, (ii) is a left and right side view, (iii) is a rear view, and (iv) is a top and bottom plan view.
Incidentally, a steel belt or the like is embedded in the tread portion of the tire so as to keep the tread surface flat. For this reason, it is necessary to prevent excessive twisting and bending from acting on the tread surface when the tread surface is bent, and to maintain the planar state of the tread surface 2d.
As shown in FIG. 2, according to the method of the present invention, the tire 2 can be curved while the planar state of the tread surface 2d is substantially maintained.

In order to bring the first proximity points 2a and 2a and the second proximity points 2b and 2b closer to each other, as shown in FIG. 3A, the first proximity points 2a and 2a on the other side surface 2f The urging forces I and I and the urging forces II and II may be simultaneously applied to the corresponding portions and the portions corresponding to the second proximity points 2b and 2b on the one side surface 2e.
By doing so, a curved shape as shown in FIG. 2A is obtained.

  In addition to the method shown in FIG. 3 (a), as shown in FIG. 3 (b), the first proximity points 2a, 2a or the second proximity points 2b, 2b are moved closer to each other (direction indicated by reference numeral III). While applying an urging force, an urging force (indicated by reference numeral IV) may be applied on an axis crossing the approaching direction.

When the width dimension in the direction crossing the tread surface 2d (the dimension indicated by the symbol H2 in FIG. 2A) is equal to or close to the hole diameter H1 of the wheel mounting hole 1c of the tire 1, FIG. The tire 2 is inserted into the mounting hole 1c from the tread surface 2d as shown in FIG.
The relationship between the hole diameter H1 and the width dimension H2 may be the same, or the width dimension H2 may be small. Further, since the tires 1 and 2 are elastic, the width dimension H2 may be slightly larger than the hole diameter H1 within the range.

  Then, with the tire 2 inserted into the wheel mounting hole 1c of the tire 1, the maintenance of the curve is released. As a result, the tire 2 is developed by its own elastic force and incorporated into the tire 1. At this time, a part of the tire 2 protruding outside the wheel mounting hole 1c may be caught on the hole periphery of the wheel mounting hole 1c, but by pushing the wheel 1 into the wheel mounting hole 1c while deforming the tires 1 and 2, As shown in FIG. 1B, the tire 2 can be incorporated into the tire 1.

[Description of embedded device configuration]
Next, an embodiment of an assembling apparatus used when the above assembling method is carried out. This will be described with reference to FIGS.
FIG. 4 is a schematic diagram for explaining an overall configuration according to an embodiment of the assembling apparatus, FIG. 5A is an enlarged explanatory view of a main part of the first hook device in the assembling apparatus, and FIG. FIG. 6A is a diagram for explaining the action of the push rod of the first hook device, FIG. 6A is an enlarged view of the hook of the second hook device, and FIG. 6B is a diagram for explaining the action of the hook. 7 is a diagram (a cross-sectional view of the tire) illustrating the relationship between the hook of the second hook device and the first hook device when the tire is curved, (a) is a front view thereof, and (b). Is a side view thereof.

  As shown in FIG. 4, the assembling apparatus 3 includes a frame 301 having a column 302 at one end, a slide guide 302 attached to the upper surface of the frame 301, a direction approaching each other while being guided by the slide guide 302, and a distance from each other. A pair of first hook devices 330, 330 that move forward and backward in the direction to be moved, first drive means mainly composed of a motor 311 that moves the first hook devices 330, 330 forward and backward, and a horizontal position from the upper end of the column 302. And a second hook device 340 including a pair of hooks 341 and 341 that are suspended by a wire 342 and moved up and down by a winch 343.

[Configuration of Driving Means of First Hook Device]
The first driving means includes a motor 311 attached to the frame 301, a speed reducer 312 that decelerates the rotation of the rotating shaft 311 a of the motor 311 and outputs the reduced speed to the output shaft 315, and slide guide 302 and the upper surface of the frame 301. And a screw shaft 313 in which both ends are supported by a bearing 317 and spiral grooves 313a and 313b that are reverse spirals are formed symmetrically, and a sprocket 314 attached to one end of the screw shaft 313 And a chain 316 wound around the sprocket 314 and the output shaft 315. One of the pair of first hook devices 330 is screwed into one spiral groove 313a of the spiral shaft 313, and the other first hook device 330 is screwed into the other spiral groove 313b.

The motor 311 can rotate the rotating shaft 311a in the forward and reverse directions. In order to prevent the first hook devices 330 and 330 from moving due to the elasticity of the tire 2 and the like when the driving of the motor 311 is stopped, in this embodiment, the spiral groove and the spiral mountain are formed in a square shape. A formed spiral shaft 313 of a square spiral type is used. Of course, other means such as a brake mechanism may be provided.
When the motor 311 is driven by operating the foot switch 318 or the like, the rotation of the rotation shaft of the motor 311 is transmitted from the output shaft 315 to the spiral shaft 313 via the chain 316 and the sprocket 314, thereby rotating the spiral shaft 313. Thereby, the spiral shaft 313 rotates in the forward rotation direction or the reverse rotation direction, and the first hook devices 330 and 330 are moved forward and backward in a direction approaching each other or a direction separating from each other.

[Configuration of the first hook device]
Details of the first hook devices 330 and 330 will be described with reference to FIG. Since the first hook devices 330 and 330 have the same configuration except that they are symmetrically screwed to the spiral shaft 313, only one of the first hook devices 330 (left side in the figure) will be described, and the other one will be described. Detailed description is omitted.
The first hook device 330 is screwed into one spiral groove 313 a of the spiral shaft 313 and moves forward and backward while being guided by a guide groove 321 formed in the slide guide 320, and is erected on the slider 331. The support body 332, a swing arm 335 swingably mounted near the upper end of the support body 332, and a push rod 336 provided at the upper end of the support body 332.
Although not particularly illustrated, a spring that constantly urges the push rod 336 toward the swing arm 335 may be provided at the upper end of the support 332. Further, adjusters 336a and 336a as shown in the figure may be provided at one end of the push rods 336 and 336 that are in contact with each other so that the lengths of the push rods 336 and 336 can be adjusted. The adjuster portions 336a and 336a may be formed, for example, by forming a spiral hole at the one end of the push rods 336 and 336, screwing a bolt into the spiral hole, and fixing with a nut or the like.

  The push rod 336 is inserted into a through hole formed at the upper end of the support body 332, and can move forward and backward in the same direction as the forward and backward movement direction of the first hook device 330 while being guided by the through hole. In addition, one end (the left end in the figure) of the push rod 336 is positioned so as to face the upper end of the swing arm 335.

  The swing arm 335 is swingably provided via a shaft 334 on a bracket 333 that protrudes in one direction (leftward in FIG. 5) from the vicinity of the upper end of the support 332. The shaft 334 may be fixed to the bracket 333 with a C-ring, bolt / nut, or welding, but a temporary fixing means such as a clip is provided so that the swing arm 335 and the support 332 can be easily and quickly separated. It is preferable that the bracket 333 be detachably used.

  The lower end of the swing arm 335 does not damage the tire 2 when engaged with the tire 2 and allows the lower end of the swing arm 335 to move smoothly with respect to the tire 2 when being bent. For this purpose, a rotatable roller 335a is attached. Of course, if the same purpose can be achieved, a resin or metal sphere may be attached instead of the roller 335a, or the lower end of the swing arm 335 may be formed in a warp shape.

In the pair of first hook devices 330 and 330, the push rods 336 and 336 are arranged on the same axis, and the first hook devices 330 and 330 are arranged at a predetermined distance (depending on the length of the push rods 336 and 336). When approaching the distance), the push rods 336 and 336 come into contact with each other.
At this time, even if the first hook devices 330 and 330 move in a direction in which they approach each other, the movement of the push rods 336 and 336 is restricted to each other. Therefore, as shown in FIG. , 336 contact the upper ends of the swing arms 335, 335, and rotate the swing arms 335, 335 to bring the lower ends of the swing arms 335, 335 closer to each other. That is, in the final stage of the bending process of the tire 2, the pivoting movement of the swing arms 335 and 335 is added to the approaching action of the pair of first hook devices 330 and 330, so that the second approach points 2b and 2b It can be moved to the approached position.

[Configuration of second hook device]
The second hook device 340 includes a hollow support 302, a wire 342 that passes through a hollow arm 303 provided in the horizontal direction at the upper end of the support 302, and a pair of wires suspended from the tip of the wire 342. Hooks 341 and 341 and a winch 343 including a drum 344 for winding the wire 342 are provided. Reference numerals 305a and 305b are pulleys for guiding the wire 342 unwound from the drum 344 to the tip of the arm 303, and the hooks 341 and 341 suspended from the pulley 305a are connected to the pair of first hook devices 330 and 330, respectively. It is located almost in the middle. Reference numeral 348 denotes a switch such as a foot switch for driving the winch 343.

By the way, it is preferable that the positions where the hooks 341 and 341 are hooked in the tire 2 are orthogonal to the positions where the swing arms 335 and 335 are hooked. If the position is shifted from the orthogonal direction, a desired curved shape may not be obtained. In such a case, it is preferable to correct the positions of the hooks 341 and 341. The inventor has found that this modification can be easily performed by devising the shapes of the hooks 341 and 341. Hereinafter, the hooks 341 and 341 will be described with reference to FIG.
FIG. 6 is an enlarged view for explaining details of the hooks 341 and 341. Since the two hooks 341 and 341 have the same shape, only one of them will be described, and a detailed description of the other will be omitted.
As shown in FIG. 6A, the hook 341 includes a V-shaped hook portion 341 a that engages with the peripheral edge of the wheel mounting hole 2 c of the tire 2 at one end, and is connected to the wire 342 at the other end. A portion 341c is formed. An arcuate curved portion 341b is formed between the connecting portion 341c and the hook portion 341a.
As shown in FIGS. 6B and 6I, when the hook portion 341a is hooked on the periphery of the wheel mounting hole 2c of the horizontally placed tire 2 and the wire 342 is pulled in the direction of the arrow to raise the hook 341, FIG. 6 (b) (ii), the hook 341 also changes its position as the tire 2 curves. In this case, even if the positions of the hooks 341 and 341 are slightly deviated from the predetermined positions, the hooks 341 and 341 are formed in the shape as described above, so that the positions of the hooks 341 and 341 can be easily corrected manually. can do.

FIG. 7 shows a state when the tire 2 is bent into a predetermined shape by the cooperation of the first hook devices 330 and 330 and the second hook device 340. It is a cross section at a part. (A) is a cross section taken along a plane perpendicular to the advancing / retreating direction of the first hook devices 330, 330, and (a) is a cross section taken along a plane parallel to the advancing / retreating direction of the first hook devices 330, 330. is there.
As can be seen from FIG. 7, the hooks 341 and 341 of the second hook device 340 approach the first proximity points 2a and 2a while the first hook devices 330 and 330 approach the second proximity points 2b and 2b. By doing so, the curved form shown in FIG. 2 can be obtained.
7B, in this embodiment, the distance L1 between the bracket 333 that supports the swing arms 335 and 335 and the tips of the swing arms 335 and 335 is set to the side surface 2f of the tire 2. It is formed larger than the width L2. At the final stage of the bending process of the tire 2, the rollers 335a and 335a of the swing arms 335 and 335 are positioned inside the boundary portion between the tread surface 2d and the side surface 2f, and the swing arms 335 and 335 are pushed. By rotating by the action of the rods 336 and 336, an action of narrowing the lower end portion of the curved tire 2 occurs. As a result, the tread surfaces 2d and 2d are inclined as shown in FIG. 7B, and the positions of the tread surfaces 2d and 2d when the narrowing is not performed are compared with the case where the narrowing is not performed. ), The width at the time of bending is reduced by ΔH2 on one side, and insertion into the tire 1 can be made easier.

[Embedded device action]
Next, the operation of the built-in apparatus having the above configuration will be described with reference to FIGS.
First, the gap between the first hook devices 330 and 330 is adjusted while moving the pair of first hook devices 330 and 330 forward and backward, and the pair of first hook devices 330 is attached to the wheel mounting holes of the tire 2 as shown in FIG. 2c (see FIG. 1). Further, the tire 1 is prepared by being suspended from the arm 303. Thereafter, the hooks 341 and 341 of the second hook device 340 are engaged with the tire 2. The positions at which the hooks 341 and 341 are engaged are as described with reference to FIGS.

  In this state, the switch 348 (see FIG. 4) is operated to drive the winch 343 to wind the wire 342 around the drum and raise the hooks 341 and 341. Further, in conjunction with this, the switch 318 (see FIG. 4) is operated to drive the motor 311 and, as shown in FIG. 8B, the pair of first hook devices 330, 330 are brought closer to each other. Move. At this time, the roller 335a at the tip of the swing arm 335 is positioned inside the tire 2 as shown in FIG.

  Even if the hooks 341 and 341 are raised, the tire 2 is held by the swing arms 335 and 335 of the pair of first hook devices 330 and 330 in the vicinity of the second proximity points 2b and 2b (see FIG. 1). In addition, since the pair of first hook devices 330 and 330 move in a direction approaching each other, as shown in FIG. 8B and FIG. Start to curve.

  As shown in FIG. 9A, when the first hook devices 330 and 330 move to a predetermined place, the push rods 336 and 336 come into contact with each other, and the movement is restricted. Then, when the upper ends of the swing arms 335 and 335 come into contact with the tips of the push rods 336 and 336, the swing arms 335 and 335 start to rotate. By the rotation of the swing arms 335 and 335 and the approaching operation of the first hook devices 330 and 330, the curved shape of the tire 2 is fixed in a state where the second proximity points 2b and 2b are closest to each other. At this time, as described with reference to FIG. 7B, the tire 2 is narrowed down by the swing arms 335 and 335, and the tread surfaces 2d and 2d are inclined, so that the entire width of the tire 2 during bending is increased. It can be made smaller.

  After fixing the curved shape of the tire 2, as shown in FIG. 9B, the tire 1 suspended from the arm 303 and put on standby is put on the tire 2, and the tire 1 is put in the wheel mounting hole 1c of the tire 1. 2 is inserted. As described above, by performing “squeezing” at the final stage of the bending process of the tire 2, the entire width of the tire 2 can be further reduced, and the tire 1 can be easily inserted into the mounting hole 1 c. If the first hook devices 330 and 330 are moved away from each other while lowering the hooks 341 and 341 in this state, the tire 2 is loosened by self-elasticity, and the hooks 341 and 341 can be removed. At the same time, the swing arms 335 and 335 are also free.

  In this embodiment, as shown in FIG. 9C, the swing arms 335 and 335 are removed from the first hook devices 330 and 330 so as not to interfere with the subsequent work. In this state, the pair of first hook devices 330 and 330 are moved away from each other, and the tire 2 is forcibly pushed out by the support bodies 332 and 332 as shown in FIG. As a result, as shown in FIG. 10B, the tire 2 is incorporated into the tire 1 and the operation is completed. If the tire 2 cannot be completely inserted into the tire 1 only by the self-elasticity of the tire 2 and the forced deployment by the supports 332 and 332, a part of the tire 2 protruding from the tire 1 by an auxiliary manual operation Is pushed into the tire 1.

Although the embodiment of the present invention has been described, the present invention is not limited to the above description.
For example, in the above description, the first driving means is composed of the motor 311, the spiral shaft 313, and the like as an example, but the first hook device is moved in a direction toward and away from each other. If possible, a hydraulic or pneumatic cylinder may be used, and further, a manual type as constituted by a helical shaft similar to the helical shaft 313 and a handle attached to one end of the helical shaft. Are also included in the concept of the first drive means of the present invention.

In the above description, in the final stage of the bending process of the tire 2, the pair of push rods 336, 336 are brought into contact with each other to rotate the swing arms 335, 335. If the swing arms 335 and 335 can be rotated by the push rods 336 and 336 following the approaching operation of the devices 330 and 330, the push rods 336 and 336 do not necessarily have to be brought into contact with each other. For example, a restricting means for restricting the movement of the first hook device 330 by bringing the push rod 336 of the other first hook device 330 into contact therewith may be provided. Further, if the swing arms 335 and 335 can be rotated at the final stage of the bending process of the tire 2, a driving body such as a cylinder or a solenoid may be used instead of the push rod 336.
Further, in the above description, the case where one tire is incorporated into another tire has been described, but the present invention can also be applied to the case where two or more tires are incorporated into another tire. Further, in the above description, the tire 2 is bent in the left-right direction, and the tire 1 and the tire 2 are assembled from the vertical direction. For example, the tire 2 can be bent in the vertical direction, and the tires 1 and 2 can be incorporated from the left and right directions.
