Accordingly, specific dimensions and the like should be determined in consideration of the following description. Moreover, the part from which the relationship and ratio of a mutual dimension differ also in between drawings is contained.

(1) Tire component supply device A tire component supply device will be described. FIG. 1 is a plan view of a tire component supply device 100, and FIG. 2 is a front view of the tire component supply device 100. The tire component supply device 100 is a device for supplying the first component 10A and the second component 20A as tire components to a drum as an assembly mechanism located on the downstream side in the transport direction. More specifically, the tire component supply device 100 constitutes a part of the tire manufacturing apparatus, supplies the component constituting the tire to a drum 200 (assembly mechanism) supported rotatably, and the drum. It is used when an unvulcanized tire is formed by wrapping a structural member around a steel sheet.

  The tire component supply device 100 includes a delivery mechanism 110, a transport mechanism 120, a cutting mechanism 130, a position acquisition mechanism 140, a component adjustment mechanism (the adjustment mechanism of the present invention), and an auxiliary imaging mechanism 150. Have.

  The delivery mechanism 110 holds the first continuous body 10 in which the first constituent member 10A constituting the tire is continuous and the second continuous body 20 in which the second constituent member 20A constituting the tire is continuous. The second continuous bodies 20 are sent out toward the transport mechanism 120, respectively. The 1st continuous body 10 and the 2nd continuous body 20 are strip | belt-shaped members, and are wound by roll shape. By cutting the first continuous body 10 with a predetermined length L, the first component member 10A is formed. Also, the second component 20A is formed by cutting the second continuous body 20 by a predetermined length L. The continuous direction of the first structural member 10A (the continuous direction of the second structural member 20A) is the transport direction of the first continuous body 10 (the transport direction of the second continuous body 20) MD.

  The delivery mechanism 110 includes a rotating body around which the first continuous body 10 and the second continuous body 20 are wound. The rotating body is configured to be rotatable around a rotation axis, and continuously feeds the first continuous body 10 and the second continuous body 20 by rotating. Since both the first continuum 10 and the second continuum are wound around one rotating body, it is easy to match the amount sent out by the first continuum and the amount sent out by the second continuum.

  The first continuous body 10 and the second continuous body 20 are sent out by providing driving means for rotating the rotating body, and the first continuous body 10 and the second continuous body 20 are sequentially sent out by the driving means. Alternatively, the first continuum 10 and the second continuum 20 may be pulled by the transport mechanism 120 to the downstream side in the transport direction without providing a driving unit for rotating the rotator. You may be comprised so that the bicontinuous body 20 may be sent out sequentially.

  The continuous direction of the first component member 10A and the continuous direction of the second component member 20A are parallel to each other along the transport direction. Therefore, the delivery mechanism 110 can match the length for sending the first continuous body 10 with the length for sending the second continuous body 20. The 1st continuous body 10 and the 2nd continuous body 20 are arrange | positioned at intervals in the cross direction CD orthogonal to conveyance direction MD.

  The transport mechanism 120 transports the first continuous body 10 and the second continuous body 20 supplied from the delivery mechanism 110 in a state where the continuous direction of the first continuous body 10 and the continuous direction of the second continuous body are parallel. The transport mechanism 120 includes a feed roll 121, an upstream conveyor 122, and a downstream conveyor 123. From the upstream side in the transport direction to the downstream side in the transport direction, the feed roll 121, the upstream conveyor 122, and the downstream conveyor 123 are arranged in this order.

  The feed roll 121 guides the first continuous body 10 and the second continuous body 20 sent out from the delivery mechanism 110 to the downstream side in the transport direction. The upstream conveyor 122 and the downstream conveyor 123 have a rotating roll and an endless belt member spanned on the rotating roll. In addition, the upstream conveyor 122 and the downstream conveyor 123 may be comprised only by the rotating roll.

The upstream conveyor 122 includes a first upstream conveyor 1221 that transports the first continuous body 10 and a second upstream conveyor 1222 that transports the second continuous body 20. The transport direction of the first upstream conveyor 1221 and the transport direction of the second upstream conveyor 1222 are parallel.

  The downstream conveyor 123 is located downstream in the transport direction from the cutting position of the tire constituent member by the cutting device. The downstream conveyor 123 includes a first downstream conveyor 1231 that conveys the first continuum 10 and a second downstream conveyor 1232 that conveys the second continuum 20. The transport direction of the first downstream conveyor 1231 and the transport direction of the second downstream conveyor 1232 are parallel.

  At least one of the upstream conveyor 122 and the downstream conveyor 123 constitutes an adjustment mechanism, and is configured to adjust the transport distance of the first continuous body 10 and the transport distance of the second continuous body 20. In addition, adjustment of the conveyance distance of the 1st continuous body 10 and the conveyance distance of the 2nd continuous body 20 is demonstrated in detail later.

  Each time the first continuous body 10 and the second continuous body 20 are transported by a predetermined length L by the transport mechanism 120, the cutting mechanism 130 is cut at the cutting position along the crossing direction CD. Cut the body 20. The cutting mechanism 130 includes a cutter member 131 that is disposed across the first continuous body 10 and the second continuous body 20 in the cross direction CD and that cuts the first continuous body 10 and the second continuous body 20 together. .

  The cutter member 131 has a cutting blade extending along the cross direction CD, and simultaneously cuts the first continuous body 10 and the second continuous body 20 at a cutting position along the cross direction CD. In FIG. 1, a virtual line FL1 including the cutting position of the cutter member 131 and extending in the intersecting direction is shown.

  The cutter member 131 is driven by a driving means (not shown), and is disposed at a position apart from the first continuous body 10 and the second continuous body 20 except during cutting. During cutting, the first continuous body 10 and the second continuous body are disposed. It arrange | positions in the position contact | abutted to the body 20. FIG.

  In addition, the cutter member 131 is provided not only with the structure which cut | disconnects a 1st continuous body and a 2nd continuous body but also providing the cutter member for 1st continuous bodies, and the cutter member for 2nd continuous bodies separately. May be.

  The position acquisition mechanism 140 transfers the position of the first continuous body 10 in the transport direction and the transport of the second continuous body 20 while the first continuous body 10 and the second continuous body 20 are transported by a predetermined length L from the cutting position. Get the position in the direction. The position acquisition mechanism 140 of the present embodiment acquires the position of the downstream end portion 10E (see FIG. 3) in the transport direction of the first continuous body 10 as the position in the transport direction of the first continuous body, and the second continuous body 20 As the position in the transport direction, the downstream end 20E in the transport direction of the second continuous body 20 (see FIG. 3) is acquired.

  The position acquisition mechanism 140 includes a first imaging member 141 that images the downstream end portion 10E of the first continuous body 10 in the transport direction and a second imaging member 142 that images the downstream end portion of the second continuous body 20 in the transport direction. Have. The first imaging member 141 and the second imaging member 142 are located downstream of the cutting mechanism 130 in the transport direction. The first imaging member 141 and the second imaging member 142 are a first continuum between a virtual line FL1 including a cutting position and a position FL2 having a predetermined length L from the virtual line FL1 toward the downstream side in the transport direction. 10 and the second continuum 20 are imaged.

  The position acquisition mechanism 140 may image the first continuum 10 and the second continuum 20 that are being transported, or may capture the first continuum and the second continuum that are temporarily stopped at the imaging position. In the present embodiment, in order to improve the position detection accuracy, the first continuum and the second continuum that have been temporarily stopped at the imaging position are imaged.

  The first imaging member 141 and the second imaging member 142 are fixed to a common support base 143. Furthermore, the support base 143 is fixed to a support mechanism 160 that is common to the downstream conveyor 123 constituting the transport mechanism. Or the 1st imaging member 141 and the 2nd imaging member 142 may be fixed to another support stand, and the support stand 143 may be fixed separately from the downstream conveyor 123 which comprises a conveyance mechanism. A shift in relative position between the first imaging member 141 and the second imaging member 142 can be suppressed, and a shift in relative position between the first imaging member 141 and the second imaging member 142 and the transport mechanism 120 can be suppressed.

  The position acquisition mechanism 140 may be configured to acquire the time when the first continuum 10 has passed through a predetermined point and acquire the position in the transport direction of the first continuum from the time that has passed. And you may comprise so that positions other than the conveyance direction downstream end part 10E of the 1st continuous body 10 may be acquired.

  The auxiliary imaging mechanism 150 is disposed downstream of the position acquisition mechanism 140 in the transport direction. The auxiliary imaging mechanism 150 images the first component member 10A from which the first continuum is cut and the second component member 20A from which the second continuum is cut. The distance in the transport direction between the imaging position of the auxiliary imaging mechanism 150 and the imaging position of the first imaging member 141 is a predetermined length L. The distance in the transport direction between the imaging position of the auxiliary imaging mechanism 150 and the imaging position of the second imaging member 142 is a predetermined length L.

  The auxiliary imaging mechanism 150 images the downstream end portion in the transport direction of the first component member 10A and the downstream end portion in the transport direction of the second component member 20A, and the first imaging member 141 and the second imaging member 142 are the first component member. The upstream end in the transport direction of 10A and the upstream end in the transport direction of the second component member 20A are imaged. Therefore, based on the imaging result of the auxiliary imaging mechanism and the imaging result of the first imaging member 141, it can be determined whether or not the first component member 10A has been cut at the predetermined length L. Further, based on the imaging result of the auxiliary imaging mechanism and the imaging result of the second imaging member 142, it can be determined whether or not the second component member 20A has been cut at a predetermined length L.

  The position acquisition mechanism and the auxiliary imaging mechanism only need to be able to detect the position of the target member, and can be configured by a camera or a sensor.

  The adjustment mechanism includes a control mechanism (not shown) and a transport mechanism 120. While the first continuum 10 and the second continuum 20 are transported by a certain length L from the cutting position based on the position in the transport direction of the first continuum 10 and the position in the transport direction of the second continuum 20. The transport distance of the first continuous body 10 and the transport distance of the second continuous body 20 are adjusted so that the lengths in the transport direction of the first continuous body and the second continuous body coincide with each other.

  More specifically, the control mechanism of the adjustment mechanism acquires the length in the transport direction of the first continuum and the length in the transport direction of the second continuum from the position acquisition mechanism, and the length in the transport direction of the first continuum. And the length of the second continuum in the transport direction are compared. The control mechanism controls the transport mechanism 120 to adjust the transport distance of the first continuum and the transport distance of the second continuum while being transported by a certain length from the cutting position. By adjusting in this way, the position of the downstream end portion in the transport direction of the first continuum and the position of the downstream end portion in the transport direction of the second continuum are made to coincide with each other in a state where it is transported by a certain length from the cutting position. be able to.

(2) Supply Method of Tire Constituent Member Next, a method of supplying a tire constituent member using the above-described tire constituent member will be described with reference to FIGS. 3-6 is a figure for demonstrating each process in the supply method of a tire structural member.

  The tire component supply method includes at least a delivery step, a conveyance step, a cutting step, a position acquisition step, and an adjustment step.

  In the sending process, the sending mechanism 110 continuously sends the first continuous body 10 and the second continuous body 20 downstream in the transport direction. A conveyance process conveys the 1st continuous body 10 and the 2nd continuous body 20 which are supplied by the delivery process in the state where the continuous direction of 10 A of 1st component members and the continuous direction of 20 A of 2nd component members are parallel.

  In the cutting process, every time the first continuous body 10 and the second continuous body 20 are conveyed by a certain length, the first continuous body 10 and the second continuous body 20 are orthogonal to the continuous direction at a cutting position along the crossing direction. Cut in the direction to be cut or at an inclination angle. 1 and 2 show a state where the first continuous body 10 and the second continuous body are cut by the cutting process. The first component member 10A and the second component member 20A are disposed downstream of the cutting position in the transport direction, and the first continuous member 10 and the second continuous member 20 are disposed upstream of the cutting position in the transport direction. Yes.

  When the first continuous body 10 and the second continuous body 20 are further conveyed from the state shown in FIG. 1, the state shown in FIG. 3 is obtained. In FIG. 3, the downstream end portion 10 </ b> E in the transport direction of the first continuous body 10 is arranged at the imaging position of the first imaging member 141, and the downstream end portion 20 </ b> E in the transport direction of the second continuous body 20 It is in the state arranged in. A position acquisition process acquires the position in the conveyance direction of a 1st continuous body and the position in the conveyance direction of a 2nd continuous body in the state shown in FIG.

  When the first continuous body 10 and the second continuous body 20 are further transported from the state shown in FIG. 3, the state shown in FIG. 4 is obtained. The state shown in FIG. 4 is a state in which a predetermined length L is conveyed from the position shown in FIG.

  In the adjustment step, the first continuum in the transport direction and the second continuum in the transport direction coincide with each other between the state shown in FIG. 1 and the state shown in FIG. 4. The transport distance of the continuum and the transport distance of the second continuum are adjusted. In the present embodiment, since the transport distance is adjusted based on the position imaged in the state shown in FIG. 3, the transport direction of the first continuum from the state shown in FIG. 3 to the state shown in FIG. The transport distance of the first continuum and the transport distance of the second continuum are adjusted so that the position of the second continuum matches the position in the transport direction of the second continuum.

  For example, when the position of the first continuum in the transport direction is located upstream of the position of the second continuum in the transport direction, the following control is performed. The control mechanism makes the rotation amount of the first downstream conveyor (or / and the first upstream conveyor) larger than the rotation amount of the second downstream conveyor (or / and the second upstream conveyor).

  By adjusting in this way, in the state shown in FIG. 4, the position in the transport direction of the downstream end portion in the transport direction of the first continuum matches the position in the transport direction of the downstream end portion in the transport direction of the second continuum. .

  When the first continuous body 10 and the second continuous body 20 are further transported from the state shown in FIG. 4, the state shown in FIG. 5 is obtained. The downstream end portion in the transport direction of the first constituent member 10A and the downstream end portion in the transport direction of the second constituent member 20A are disposed at the imaging position of the auxiliary imaging mechanism. The upstream end portion in the transport direction of the first component member 10A is disposed at the imaging position of the first imaging member 141, and the upstream end portion in the transport direction of the second component member 20A is disposed at the imaging position of the second imaging member 142. Yes.

  The control mechanism can acquire the measured length of the first component member based on the imaging result of the auxiliary imaging mechanism and the imaging result of the first imaging member 141, and the imaging result of the auxiliary imaging mechanism and the imaging of the second imaging member 142. Based on the result, the measured length of the second component member can be acquired. For example, the winding mode of the first component member and the second component member around the drum can be changed based on the actually measured length of the first component member and the actually measured length of the second component member.

(3) Action / Effect The tire constituent member is formed of a rubber member, a carcass ply made of a cord, or the like, and is easily shrunk in the transport direction when cut by a cutting device. Therefore, the length of the first component member may not match the second component member. However, according to the tire component supply device 100 according to the present embodiment, in the process of being transported by the transport mechanism 120, the position in the transport direction of the downstream end of the first continuous body 10 in the transport direction and the second continuous body The position in the transport direction of the downstream end portion in the transport direction can be matched. Therefore, the length in the transport direction of the first component member 10A can be matched with the length in the transport direction of the second component member 20A. Variation in the length of the tire constituent members constituting the tire can be suppressed.

  Adjustment of the conveyance distance of the 1st continuous body 10 and the conveyance distance of the 2nd continuous body 20 is performed while conveying a fixed length from a cutting position. When the conveyance distance of the first continuum 10 and the conveyance distance of the second continuum 20 are adjusted after being conveyed by a certain length, the first continuum 10 and the second continuum 20 are conveyed by a certain length. Later, it is necessary to move the first continuum 10 and the second continuum 20 in the up and down conveyance direction, and the conveyance process becomes complicated. However, the conveyance process can be simplified by adjusting the conveyance distance of the first continuum 10 and the conveyance distance of the second continuum 20 during the conveyance of a certain length from the cutting position.

  Further, since the first component member 10A is attached to one side in the tire width direction and the second component member 20A is attached to the other side in the tire width direction, the length of the first component member and the length of the second component member are If they are different, there is a risk of affecting the motion performance and uniformity performance of the finished tire. However, since the amount of deviation between the length of the first component member and the length of the second component member can be greatly reduced, it is possible to suppress a decrease in the motion performance and uniformity performance of the finished tire.

  The position acquisition mechanism 140 includes a first imaging member 141 and a second imaging member 142. By photographing the first continuum 10 and the second continuum 20 that are separately transported by individual imaging members, the positional accuracy of the first continuum 10 in the transport direction and the position accuracy of the second continuum 20 in the transport direction. The amount of deviation between the length of the first component member 10A and the length of the second component member 20A can be further reduced. In addition, by photographing the first continuum 10 and the second continuum 20 that are separately conveyed with individual imaging members, it is possible to reduce the time for position acquisition as compared with the case of imaging with one imaging mechanism. Can be reduced.

  The first imaging member 141 and the second imaging member 142 are fixed to the support mechanism 160 together with the transport mechanism 120. Therefore, it is possible to suppress the positional deviation between the first imaging member and the second imaging member and the positional deviation between the imaging member and the transport mechanism. Therefore, it is possible to suppress a decrease in detection accuracy due to the displacement of the imaging member.

The cutting mechanism 130 includes a cutter member 131 that cuts the first continuous body 10 and the second continuous body 20 together. In order to cut the first continuous body 10 and the second continuous body 20 with the same cutter member 131, the cutting position is compared with the configuration in which the first continuous body 10 and the second continuous body 20 are cut by separate cutting mechanisms 130. The deviation of 130 can be suppressed. Moreover, the cutting processing time can be shortened.
(4) Other Embodiments As described above, the present invention naturally includes various embodiments that are not described herein. Therefore, the technical scope of the present invention is defined only by the invention specifying matters according to the scope of claims reasonable from the above description.

  Next, a tire component supply device 100A according to a modification will be described with reference to FIGS. Note that in the tire component supply device according to the modification, the same components as those of the tire component supply device according to the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. The tire component supply device 100A according to the modification further includes a vertical direction adjustment mechanism 170 and a swing mechanism 180.

  The vertical direction adjustment mechanism 170 adjusts the position in the vertical direction of the downstream conveyor 123 as a transport mechanism. The vertical direction adjustment mechanism 170 is configured to move the downstream conveyor 123 and the support mechanism 160 that supports the downstream conveyor 123. The vertical direction adjustment mechanism 170 reciprocates the downstream conveyor 123 and the support mechanism 160 in the vertical direction.

  The vertical direction adjustment mechanism 170 is disposed below the support mechanism 160. The vertical direction adjustment mechanism 170 includes a contact position where the first component member 10A and the second component member 20A positioned on the downstream conveyor 123 are in contact with the surface of the drum 200, and a first component member 10A positioned on the downstream conveyor. Further, the downstream conveyor 123 is moved between the second component member 20 </ b> A and the separated position where the second component member 20 </ b> A is moved downward from the surface of the drum 200. The vertical direction adjustment mechanism 170 includes a first support base 171, a second support base 172, and a drive mechanism (not shown). The first support base 171 is slid in the vertical direction along the movement axis 173 extending in the vertical direction.

  FIG. 6 shows a state in which the downstream conveyor is inclined, and the upstream end portion in the transport direction of the downstream conveyor is arranged so as to be connected to the upstream conveyor. In FIG. 7, the downstream conveyor 123 is in the separated position, and the second support base 172 is adjacent to the first support base 171. When the second support base 172 moves upward along the movement axis 173 from the state shown in FIG. 7, the state shown in FIG. 8 is obtained. FIG. 8 shows a state in which the downstream conveyor 123 is in the contact position, and the second support base 172 is separated from the first support base 171.

  The vertical direction adjustment mechanism 170 is configured to realize only reciprocal movement along the vertical direction and not to move or swing in the horizontal direction. Therefore, the vertical direction adjusting mechanism 170 moves the downstream conveyor upward in a state where the conveyance direction of the downstream conveyor 123 is in the horizontal direction, and drums the first component member 10A and the second component member 20A on the downstream conveyor. Abut on the surface of

  The swing mechanism 180 swings the downstream conveyor 123 with a swing shaft 181 disposed in parallel with the rotation shaft of the drum as a base point. The swing mechanism 180 moves the downstream end in the transport direction of the downstream conveyor along an arcuate locus in the front views of the tire component supply device 100 shown in FIGS.

  The swing mechanism 180 includes a state in which the transport direction of the downstream conveyor 123 is in the horizontal direction and a state in which the transport direction of the downstream conveyor 123 is inclined with respect to the horizontal direction (the upstream side in the transport direction is positioned relatively upward, State in which the downstream side in the direction is positioned relatively downward). FIG. 6 shows a state in which the downstream conveyor is inclined, and the upstream end portion in the transport direction of the downstream conveyor is arranged so as to be connected to the upstream conveyor. FIG. 8 shows a state in which the downstream conveyor is along the horizontal direction, and the upstream end in the transport direction of the downstream conveyor is located below the upstream conveyor.

  In the tire component supply method, the conveyor position adjustment step is executed before the first component and the second component formed by the cutting step are sent out to the drum. Specifically, the conveyor position adjusting step includes an angle adjusting step for adjusting the inclination angle of the downstream conveyor and a vertical direction adjusting step for adjusting the vertical position of the downstream conveyor.

  The angle adjustment step adjusts the angle of the downstream conveyor from the state where the downstream conveyor is inclined to the state where the downstream conveyor is along the horizontal direction. Before executing the angle adjustment process, the upstream end of the downstream conveyor in the transport direction is placed on the extension line of the first conveyor in the transport direction so that it can receive the first continuum transported by the upstream conveyor, etc. Has been. FIG. 6 shows a state before the angle adjustment process is executed.

  After executing the angle adjustment process, the conveyance direction of the downstream conveyor is in a state along the horizontal direction. FIG. 7 shows the state after the angle adjustment process is performed and the conveyance direction of the downstream conveyor is along the horizontal direction. In this state, the upstream end of the downstream conveyor in the transport direction is located below the upstream conveyor, and the downstream end of the downstream conveyor in the transport direction is located below the drum 200.

  The angle adjustment step may be configured to adjust the inclination angle of the downstream conveyor while moving the first component member and the second component member along the transport direction by the downstream conveyor, or by the downstream conveyor. You may comprise so that the inclination angle of a downstream conveyor may be adjusted in the state which stopped conveyance of the 1st component member and the 2nd component member.

  The vertical direction adjustment step is executed after the angle adjustment step. A vertical direction adjustment process moves the downstream conveyor 123 arrange | positioned along a horizontal direction upwards. FIG. 8 shows a state after the vertical direction adjustment step is executed, and the first component member 10 </ b> A and the second component member 10 </ b> B on the downstream conveyor are in contact with the outer surface of the drum 200. Next, the first component member 10 </ b> A and the second component member 20 </ b> A are transferred from the downstream conveyor to the drum 200 and wound around the drum 200.

  The tire component supply device 100 moves the transport mechanism 120 upward in a state where the transport direction of the transport mechanism 120 is along the horizontal direction by a vertical direction adjustment mechanism 170 that reciprocates the transport mechanism 120 along the vertical direction. To do. When the tire constituent member is brought into contact with the outer surface of the drum, the transport mechanism 120 is moved only along the vertical direction. Therefore, the transport mechanism 120 is moved along the vertical direction while the inclination angle of the transport mechanism 120 is adjusted. Compared with the configuration, the positional accuracy of the transport mechanism 120 in the vertical direction can be increased, and the accuracy of the gap between the front end portion of the downstream conveyor, which is the front end portion of the transport mechanism, and the drum 200 can be increased. Further, since the transport mechanism is reciprocated in the vertical direction, it can be realized by a simple mechanism.

  Further, the tire component supply device 100 includes a swinging mechanism 180 that is driven independently from the vertical direction moving mechanism 170. The position of the downstream conveyor 123 with respect to the upstream conveyor 122 located upstream of the swinging mechanism 180 in the transport direction can be adjusted.

  The swing mechanism 180 includes a first position where the upstream end of the downstream conveyor 123 in the transport direction is located downstream of the cutting position in the transport direction, the transport direction of the downstream conveyor along the horizontal direction, and an upstream end of the transport mechanism in the transport direction. The downstream conveyor is moved to a second position where the section is located below the cutting position. The first position is the position shown in FIG. The second position is the position shown in FIG. With this configuration, in the vertical direction, the first position where the upstream end in the transport direction of the downstream conveyor delivers the tire constituent member and the second position where the downstream end in the transport direction of the downstream conveyor delivers the tire constituent member to the drum The position can be varied.

  In general, when supplying a continuous body, a certain amount of the continuous body is held by a feed roll 121 or the like between the position where the continuous body is wound in a roll shape and the position of the upstream conveyor 122 that conveys the continuous body. Configured as follows. In order to secure an amount for holding the continuous body, the feed roll 121 is set at a relatively high position in the vertical direction. In the supply device of the present embodiment, the swing mechanism 180 causes the vertical conveyor between the position where the downstream conveyor 123 receives the tire component from the upstream conveyor 122 and the position where the downstream conveyor 123 delivers the tire component to the drum 200. The position can be adjusted.

  Therefore, the position where the downstream conveyor 123 receives the tire component from the upstream conveyor 122 can be set to a relatively high position, and the position where the downstream conveyor 123 delivers the tire component to the drum 200 can be set to a relatively low position. Therefore, even when the feed roll 121 is set at a relatively high position in the vertical direction, the tire constituent member can be smoothly transferred from the feed roll 121 to the downstream conveyor 123.

  In addition, when it is not necessary to ensure the quantity which hold | maintains a continuous body, you may adjust the position of the downstream conveyor 123 only by the vertical direction adjustment mechanism 170, without providing the rocking | fluctuation mechanism 180. FIG. In addition, when a part of the floor surface on which the tire component supply device 100 is placed is recessed and a continuous body held by the feed roll 121 can be stored in the recess, the feed roll 121 needs to be disposed relatively high. There is no. Therefore, the position of the downstream conveyor 123 may be adjusted only by the vertical direction adjustment mechanism 170 without providing the swinging mechanism 180.

  As another modification, for example, the auxiliary imaging mechanism may be movable in the transport direction. Various tire sizes can be accommodated by changing the position of the auxiliary imaging mechanism. Further, the position acquisition mechanism may be movable in the transport direction.

  The tire component supply device of the present embodiment includes the auxiliary imaging mechanism, but may be a tire component supply device that does not include the auxiliary imaging mechanism.
