  By the way, the conventional roll body transport vehicle captures an image of a shaft portion with an imaging device, and acquires an axial center position of the shaft portion from a position of a radial end portion of the outer peripheral surface of the imaged shaft portion. The alignment processing is executed based on the axial center position in the shaft portion. However, when there are a plurality of types of roll bodies having different outer diameter dimensions of the shaft portion as a roll body to be transported by a roll body transport vehicle, the roll body is transferred to the roll body holding device or the roll body from the roll body holding device. There are the following problems when receiving.

  That is, when the roll body is delivered to the roll body holding device, if it is one type of roll body, by grasping the diameter of the shaft portion in advance, either end in the radial direction on the outer peripheral surface of the shaft portion As long as the position of the part can be discriminated, it is also possible to obtain the center position as a position shifted by a set amount in the radial direction from the position of the end part. However, when there are multiple types of outer diameter dimensions of the shaft portion, the distance between the radial end position on the outer peripheral surface of the shaft portion and the axial center position of the shaft portion is not constant. Even if the position of the end portion is determined, the center position of the shaft portion cannot be specified. Therefore, it is necessary to determine the positions of both end portions in the radial direction on the outer peripheral surface. For this reason, if one of the ends in the radial direction on the outer peripheral surface of the shaft portion cannot be identified, such as when a part of the shaft portion to be imaged is a shadow of illumination, the center position of the core is appropriately determined from the outer peripheral surface. Can not get to. As described above, when there are a plurality of types of shaft bodies having different outer diameters as the roll body to be transferred, the center position of the shaft portion may not be appropriately acquired, and the alignment process for delivery cannot be executed. there is a possibility.

  Further, when the roll body is transferred to the roll body holding device, the shaft portion is imaged by the imaging device, and the center position of the shaft portion is acquired from the positions of both ends in the radial direction of the outer peripheral surface of the imaged shaft portion. Thus, the receiving alignment process is executed based on the center position of the shaft portion. However, when there are a plurality of types of shafts having different outer diameters as the roll body to be transferred, as shown in FIGS. 13A to 13C, even when the center position of the shaft can be appropriately acquired. If the outer diameter of the roll body is different, the height of the pair of support bodies for mounting and supporting the shaft portion of the roll body is different even when the shaft center of the shaft portion is the same. It may not be possible.

Then, as the image pickup device 14, the pair of image pickup devices 14 for picking up an image of one of the pair of support pins 4 and one end of the core a in a state where the cart main body 11 is stopped at the set stop position, and the set of the cart main body 11 is stopped. The cart body 11 is provided with a total of four imaging devices 14 including a pair of imaging devices 14 that image the other end of the pair of support pins 4 and the other end of the core a in a stopped state. The pair of imaging devices 14 are provided in a state where the imaging directions intersect when viewed in the vehicle longitudinal direction.
These four imaging devices 14 are supported on the upper end portion of a support bar 18 erected on the cart body 11 so that the height can be adjusted and the direction can be adjusted.

  The control means H is supported by a pair of supports 12 and a travel control process for controlling the operation of the cart body 11 so that the cart body 11 travels to the set stop position or the cart body 11 travels from the set stop position. A transfer alignment process for controlling the operation of the moving operation means 13 so that the axis of the core a of the roll body A to be transferred is positioned at the transfer target position set for the pair of support pins 4; Positioning for receiving which controls the operation of the moving operation means 13 so that the outer peripheral surface of the core a of the roll body A to be transferred held by the body holding device 2 is placed and supported by the pair of supports 12 And processing.

  Further, the control means H performs a position acquisition process for acquiring the position information of the outer peripheral surface of the core a based on the imaging information of the imaging device 14, and an outer diameter dimension acquisition process for acquiring the outer diameter dimension information of the core a. Is configured to run. Incidentally, in this embodiment, one of the control means H and the four imaging devices 14 is provided as the outer peripheral surface position acquisition means 21 for acquiring the position of the outer peripheral surface of the core a of the roll body A to be transferred. ing. Further, one of the control means H and the four imaging devices 14 is also provided as an outer diameter acquisition means 22 for acquiring the outer diameter of the core a of the roll body A to be transferred.

  Then, the control means H has the radial direction of the core a placed and supported by the support 12 in the image captured by the imaging device 14 with the support 12 positioned at a preset setting position. Information relating to the relationship between the imaging position of the end of the core and the outer diameter of the core a, and the core a in the image captured by the imaging device 14 with the carriage body 11 stopped at the set stop position. The difference between the imaging position of the end portion in the radial direction and the imaging position of the end portion in the radial direction of the large-diameter portion 6 of the support pin 4 is defined as an end shift amount G2, and the end shift amount G2 and the outer diameter dimension of the core a. Receiving relation information indicating the relation with the is stored in advance.

When the transfer related information is described, as shown in FIGS. 7 and 8, the core a placed and supported on the support 12 is imaged in a state where the support 12 is positioned at a preset setting position. In this case, the position of the end of the core a in the radial direction in the captured image corresponds to the size of the outer diameter of the core a.
Therefore, the control means H stores in advance the relationship information for delivery indicating the relationship between the position of the radial end of the core a in the image and the size of the outer diameter of the core a. The actual outer diameter information of the core a can be acquired from the relationship information and the position of the radial end of the core a in the image. Incidentally, FIG. 9 is a graph showing the relationship between the position of the end of the core a in the radial direction in the image and the size of the outer diameter of the core a.

  The receiving related information will be described. When the roll body A is received from the same roll body holding device 2, the outer diameter of the large diameter portion 6 of the support pin 4 of the roll body holding device 2 does not change. The difference between the imaging position at the radial end of a and the imaging position at the radial end of the large-diameter portion 6 of the support pin 4 is the size of the outer diameter of the core a to be held. Correspond. That is, the control means H stores the outer diameter of the large diameter portion 6 of the support pin 4 in advance, and subtracts the outer diameter of the large diameter portion 6 that is twice the end deviation. By acquiring the outer diameter dimension of the core a on the image, and multiplying the outer diameter dimension of the core a on the image by the correction value for conversion, the actual outer diameter dimension of the core a can be acquired. It is like that.

  Regarding the position of the outer peripheral surface of the core a, when the roll body A is delivered to the roll body holding device 2, the pair of support bodies 12 are placed and supported on the support body 12 in a state where the pair of support bodies 12 are positioned at the set positions. The core a is imaged, and the position of one end in the radial direction of the core a in the captured image is set as the position of the outer peripheral surface of the core a. Further, when the roll body A is received from the roll body holding device 2, the core a supported by the pair of support pins 4 in a state in which the cart body 11 is stopped at the set stop position is imaged. The position of one end in the radial direction of the core a is the position of the outer peripheral surface of the core a. That is, the control means H can acquire the position of the outer peripheral surface of the core a from the image picked up by the image pickup device 14 at any time when receiving it.

When acquiring the outer diameter dimension of the core a and the position of the outer peripheral surface of the core a, out of both ends in the radial direction of the core a in the captured image, from the support 12 in the both ends in the radial direction of the core a. The edge part located in the upper side which leaves | separates is used.
That is, since the upper part of the core a is illuminated by lighting or the like provided on the ceiling of the production facility and the lower part of the core a is shaded by itself, the core a is illuminated when the imaging device 14 takes an image. In the upper part of the core a, it is easy to discriminate the end part by image processing, but in the lower part of the core a that becomes a shadow, it is difficult to discriminate the end part by image processing. Further, the end position of the captured image in the upper part of the core a is greatly different from the end part in the lower part of the core a depending on the size of the outer diameter of the core a.
Therefore, when acquiring the outer diameter size of the core a and the position of the outer peripheral surface of the core a, the end portion located on the upper side away from the support body 12 is used out of both end portions in the radial direction of the core a. . Note that the large-diameter portion 6 of the support pin 4 also uses an end portion located on the upper side of both radial end portions.

The control of the control means H in the case where the roll body transport vehicle 1 exchanges the roll body A with the roll body holding device 2 will be described based on the flowchart shown in FIG.
First, the traveling control process is executed to cause the traveling carriage to travel to the set stop position (S1). Incidentally, when the roll body A is transferred to the roll body holding device 2, the roll body A is placed and supported by the pair of support bodies 12, and the roll body A is not held by the roll body holding apparatus 2. When the roll body A is received from the roll body holding apparatus 2, the roll body A is not placed and supported on the pair of support bodies 12, and the roll body A is supported by the pair of support pins of the roll body holding apparatus 2. Is held.

When transferring to the roll body A to the roll body holding device 2, first, the imaging device 14 sets the core a placed and supported by the pair of support bodies 12 in a state where the pair of support bodies 12 are positioned at the set positions. In the core a of the roll body A to be transferred based on the imaging position of the radial end of the core a imaged by the imaging device 14 The position information of the outer peripheral surface is acquired (S2, S3). Next, the outer diameter dimension acquisition process for delivery is executed, and the outer diameter dimension of the core a is obtained from the imaging position of the end in the radial direction of the core a imaged by the imaging device 14 and the relation information for delivery. (S4).
Incidentally, the position acquisition process and the outer diameter acquisition process when the roll body A is delivered are placed and supported by the pair of support bodies 12 before and during the execution of the travel control process. Can be executed while

  After that, based on the positional information and the outer diameter information of the outer peripheral surface of the core a obtained from the images picked up by the four imaging devices 14, the positioning for transfer that controls the operation of the moving operation means 13 is performed. A process is performed and the core a of the roll body A of the transfer object mounted and supported by the pair of support bodies 12 is moved to a position corresponding to the pair of support pins 4 (S5). The positions corresponding to the pair of support pins 4 are positions where the pair of support pins 4 can be inserted into the core a. Specifically, the axis of the core a of the roll body A is the pair of support pins 4. This is a position in which the distance between the pair of support pins 4 and both ends of the core a is evenly aligned. In this embodiment, the difference G1 (see FIG. 10) between the position of one end portion in the radial direction of the core a and the position of one end portion in the radial direction of the large diameter portion 6 is the outer diameter dimension of the core a. This is the position corresponding to the information.

After the transfer alignment process is performed and the core a of the roll A to be transferred is moved to a position corresponding to the pair of support pins 4, the communication device 15 holds a roll ready signal in the roll. When the operation of the communication device 15 is controlled to be transmitted to the device 2 and a holding completion signal is received from the roll body holding device 2, the delivery of the roll body A is completed (S6, S7).
By the way, when the roll body holding device 2 receives a signal for completion of delivery, the pair of support pins 4 is moved from the extraction position to the insertion position to insert the pair of support pins 4 into both ends of the core a. Thereafter, the small diameter portion 5 of the pair of support pins 4 is switched to the large diameter state, and the roll body A is held by the pair of support pins 4. When the holding of the roll body A is completed in this way, the roll body holding device 2 is configured to transmit a holding completion signal to the roll body transport vehicle 1 by a communication means (not shown).

  When the roll body A is received from the roll body holding device 2, first, the roll body A and the roll body holding device held by the roll body holding device 2 by the imaging device 14 in a state where the carriage main body 11 is stopped at the set stop position. The large-diameter portion 6 in 2 is imaged, the position acquisition process for reception is executed, and the position of the radial end of the core a and the radial end of the large-diameter portion 6 of the support pin 4 in the captured image The position information of the outer peripheral surface of the core a of the roll body A to be transferred and the position information of the radial end of the outer peripheral surface of the large-diameter portion 6 of the support pin 4 are acquired based on the position of the portion (S2, S8). Next, the end portion displacement amount G2 (see FIG. 11) between the position information of the outer peripheral surface of the core a and the position information of the outer peripheral surface of the large diameter portion 6 is acquired, and the outer diameter dimension acquisition process is executed. The outer diameter dimension information of the core a is acquired from the part shift amount G2 and the receiving relation information (S9).

  Thereafter, based on the positional information and the outer diameter information of the outer peripheral surface of the core a obtained from the images captured by the four imaging devices 14, the receiving alignment for controlling the operation of the moving operation means 13. A process is performed and the pair of support bodies 12 are moved to positions where the outer peripheral surface of the core a of the roll body A held by the roll body holding device 2 is placed and supported (S10). Incidentally, the position where the outer peripheral surface of the core a of the roll body A held by the roll body holding device 2 is placed and supported is that both the pair of inclined surfaces formed on the support body 12 are the core of the roll body A. It is a position which contacts the outer peripheral surface of a.

After the receiving alignment process is performed and the pair of supports 12 is moved to a position in contact with the outer peripheral surface of the core a of the roll body A held by the roll body holding device 2, the communication device 15 When the operation of the communication device 15 is controlled so as to transmit a reception preparation completion signal to the roll body holding device 2, and the holding release completion signal is received from the roll body holding device 2, the reception of the roll body A is completed (S11). , S12).
By the way, when the roll body holding device 2 receives a signal indicating completion of reception, the roll body holding device 2 moves the pair of support pins 4 from the insertion position to the extraction position after switching the small diameter portions 5 of the pair of support pins 4 to the small diameter state. Then, the pair of support pins 4 are pulled out from both ends of the core a to release the holding on the roll body A. When the release of the holding of the roll body A is completed as described above, the roll body holding device 2 is configured to transmit a holding release completion signal to the roll body transport vehicle 1 by a communication means (not shown).

  As described above, when the roll body A is delivered to the roll body holding device 2 by performing the alignment process based on the position information of the outer peripheral surface of the core a and the outer diameter dimension information in the core a, the roll body holding device In the case where the roll body A is received from 2, a plurality of types of roll bodies A having different outer diameter dimensions of the core a can be appropriately transferred.

Moreover, both the delivery of the roll body A and the receipt of the roll body A are performed as in the above embodiment, and in both cases, the position is based on the position information of the outer peripheral surface of the core a and the outer diameter dimension information of the core a. The alignment process is executed, but the alignment process is performed based on the position information of the outer peripheral surface of the core a and the outer diameter dimension information of the core a only in either case of receiving or receiving the roll body A. May be. Specifically, for example, when both ends of the outer peripheral surface of the core a can be discriminated, when the roll body A is delivered to the roll body holding device 2, the core is like a conventional roll body transport vehicle. When the alignment process for delivery is executed based on only the position information of the outer peripheral surface in a and the roll body A is received from the roll body holding device 2, the position information of the outer peripheral surface in the core a and the outer diameter dimension in the core a You may make it perform the position alignment process for reception based on information.

One or both may be configured by means different from the imaging device 14 and the control means H.
Further, instead of using the receiving relation information and the transferring relation information, the outer diameter information of the core a is rolled from a device such as a host controller that grasps the outer diameter of the core a in the roll body A to be transferred. You may make it transmit to the receiver as the outer-diameter dimension acquisition means 22 with which the conveyance vehicle 1 was equipped.
