However, the following problems exist in the conventional technology as described above.
In order to remove the residual core attached to the rotary press, the residual core and the residual core recovery receiver are brought into contact with each other and moved up and down to move the residual core to a certain extent. In the configuration, since the remaining core collection receiver is driven to move up and down diagonally, there is a possibility that the remaining core jumps diagonally and cannot be collected during this swinging movement.
On the other hand, in the configuration described in Patent Document 2, since the remaining core recovery receiver moves up and down in the vertical direction, even if the remaining core jumps, it falls in the vertical direction, so that it can be recovered by the remaining core recovery receiver. In order to do so, two motions in the horizontal direction and the vertical direction are required, and the tact time may be delayed. Also, the structure is complicated, and for example, a cable chain or the like for housing lifting equipment is incorporated in the carriage. There is a problem that is necessary.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a roll transport cart that can reliably perform the remaining core collecting operation, shorten the tact time thereof, and reduce the size of the cart.

In order to solve the above problems, the present invention provides a first support base capable of supporting a first roll body having a first diameter with its core direction horizontal, and raising and lowering the first support base. A lifting and lowering device to be driven and a second roll body provided at a first position different from the first support base on the plane and having a second diameter larger than the first diameter in the center direction. And a second support base that can be supported by the first support base in response to the up-and-down driving of the first support base. A moving device that moves between the first position and a second position that is separated from the first support base in a direction orthogonal to the core direction of the second roll body on the plane. The structure of having is adopted.
By adopting this configuration, in the present invention, the second support base can be moved and retracted in the radial direction of the second roll body in accordance with the raising and lowering drive of the first support base. It is possible to prevent the vertical lifting path of the first support base from being closed by the second roll body supported by the base. For this reason, the first support base can be driven up and down in the vertical direction, the recovery of the remaining core can be performed reliably without being missed, and the tact time can be shortened because it is only necessary to move the first support base in the vertical direction. . Further, the first support base and the second support base can be arranged close to each other on the cart, which can contribute to the miniaturization of the cart.

In the present invention, a configuration is adopted in which a recess is formed that forms a movement path of the second support base from the first position toward the second position.
By adopting this configuration, in the present invention, the retracting path of the second support base is ensured by the recess, so that the contact with the carriage main body due to the movement of the second support base can be avoided. In addition, since the second support base can be moved directly from the first position to the second position by the recess, and it is not necessary to perform a troublesome operation of lifting the second support base and then retracting it, the tact time can be reduced. Can contribute to shortening.

In the present invention, the driving of the moving device is controlled based on the detection device that detects the diameter of the second roll body supported by the second support base and the detection result of the detection device. And a control device.
By adopting this configuration, in the present invention, the retraction movement of the second support base is controlled by the diameter of the second roll body supported by the second support base. Efficient operation according to the diameter can be realized.

Moreover, in this invention, the said control apparatus employ | adopts the structure of setting a said 2nd position based on the diameter of the said 2nd roll body supported by the said 2nd support stand.
By adopting this configuration, in the present invention, the second support base can secure a vertical lifting path of the first support base by the diameter of the second roll body supported by the second support base. Since the retreat distance is different, an efficient operation corresponding to the diameter of the second roll body can be realized by setting the second position according to the diameter of the second roll body.

In the present invention, the support surface of the first support base has a circular arc shape in cross section, and the support surface of the second support base is formed from two intersecting planes. .
By adopting this configuration, in the present invention, since the support surface of the first support base has an arc-shaped cross section, the edge is warped, and the remaining core can be recovered without being missed. In addition, since the support surface of the second support base is formed from two intersecting planes, the peripheral surface of the second roll body can be tangentially supported, and the edge does not warp. The support table can support a roll body having a diameter larger than that of the first support table.

In the present invention, a configuration is adopted in which a control device for controlling the driving of the lifting device is provided so as to reciprocate the first support base a plurality of times in the vertical direction.
By adopting this configuration, in the present invention, since the first support base moves up and down in the vertical direction when the first roll body is collected, the vertical direction even if the separated first roll body jumps. Therefore, the first roll body can be recovered without being dropped by the first support base.

According to the present invention, a first support base capable of supporting a first roll body having a first diameter with its core direction horizontal, an elevating device for driving the first support base up and down, and a plane A second roll body, which is provided at a first position different from the first support base and can support a second roll body having a second diameter larger than the first diameter with its core direction horizontal.

It has a configuration (see FIG. 3). The web support 21 is provided at a center position (first position) different from the position where the paper tube support 11 is provided on the plane of the carriage 2 (see FIG. 2A). The lifter 22 has, for example, a pantab rough mechanism shown in FIG. 2B, and moves the web support base 21 up and down in the vertical direction so that the web support base 21 is immersed in the cart 2 and protrudes vertically from the cart 2. It is configured to move between the positions to be moved. The first slider 23 is provided on the lifter 22 and is configured to slide the web support base 21 in the core direction of the web.

  The second slider 24 is provided on the first slider 23. As shown in FIG. 1, the second slider 24 of the present embodiment has a telescopic fork mechanism, a guide 25 extending in a horizontal direction perpendicular to the core direction of the web supported by the web support 21, and a guide And a driving device (not shown) that moves the web support 21 along the line 25. As the configuration of the driving device, a cylinder device, a rack and pinion device, a ball screw device or the like can be adopted. In the present embodiment, a cylinder device using an electric cylinder that directly moves by a control device (not shown) mounted on the carriage 2 is employed.

Under the control of a control device (not shown), the second slider 24 moves the web support 21 along the guide 25 along the guide 25 in accordance with the elevation drive of the paper tube support 11 and on the plane of the carriage 2. It is configured to move between a retracted position (second position) separated from the paper tube support base 11 rather than the center position in a direction orthogonal to the core direction of the web.
On the carriage 2, as shown in FIG. 1, a recess 8 is formed that forms a moving path of the web support base 21 from the center position toward the retracted position. The recess 8 functions to avoid contact with the carriage 2 when the web support 21 is moved by the second slider 24, and the web support 21 can be directly moved from the center position to the retracted position before being lifted up. It has a configuration. Note that the setting of the retracted position in the present embodiment is set in advance based on the maximum roll diameter of the web.

Next, a web feeding operation for the rotary press of the roll transport carriage 1 having the above configuration will be described with reference to FIGS. 4 and 5.
FIG. 4 is a view for explaining the paper tube collecting operation of the roll conveyance cart 1 in the embodiment of the present invention. FIG. 5 is a diagram for explaining a web feeding operation of the roll conveyance cart 1 according to the embodiment of the present invention. In addition, the code | symbol 100 shown in FIG.4 and FIG.5 has shown the winding paper mounting part of the rotary press.

  First, the roll body carriage 1 receives the web P2 directly from the storage rack (temporary storage site) by the transfer device or from the tailoring machine to the web support 21. The roll transport carriage 1 supports the web P2 on the web support 21 with its core direction horizontal, and travels toward the rotary press along the magnetic guide with the core direction as the traveling direction. After reaching the position facing the rotary press, the roll transport carriage 1 drives the steering to turn the directions of the driving wheels 3A and 3B and the driven wheels 4A and 4B by 90 degrees, and proceeds on the paper tube collecting device 10 side. Approach the rotary press as the front side.

Next, as shown in FIG. 4, the roll transport carriage 1 drives the paper tube collection device 10 to collect the paper tube P1 (remaining core) attached to the rotary press.
Specifically, the roll transport carriage 1 is first closed by the web P2 supported by the web support 21 by driving the second slider 24 and moving the web support 21 from the center position to the retracted position. The vertical lifting path of the paper tube support 11 is opened, the paper tube support 11 is lifted vertically by the lifter 12 along the opened vertical path, and the paper tube P1 and the paper tube mounted on the rotary press The support 11 is brought into contact with the support base 11 in the vertical direction.

  When the paper tube P1 and the paper tube support base 11 come into contact with each other, the roll carrier carriage 1 then moves the lifter 12 up and down to reciprocate the paper tube support base 11 a plurality of times with a predetermined width in the vertical direction. The paper tube P1 attached to the turning machine is shaken and detached several times in the vertical direction, and the paper tube support base 11 collects the paper tube P1. At this time, since the paper tube support base 11 moves up and down in the vertical direction, even if the paper tube P1 jumps, the paper tube support base 11 falls in the vertical direction, so that the paper tube support base 11 can collect the paper tube P1 without being dropped. In the recovery of the paper tube P1, the limit switch provided on the paper tube support base 11 is "ON" when it is raised due to contact with the paper tube P1, and is "OFF" when it is lowered. At this time, it is determined that the paper tube P1 has been collected on the paper tube support base 11, and the roll body transport carriage 1 ends the shaking.

  Next, the roll transport carriage 1 drives the lifter 12 to lower the paper tube support 11 that supports the paper tube P1, and the second slider 24 is used to center the web support 21 located at the retracted position. Move to position (see FIG. 5). Then, the roll transport carriage 1 moves the carriage 2 forward so that the position of the core of the web P2 supported by the web support 21 and the web loading position of the rotary press are aligned in the vertical direction. The web P2 supported on the web support 21 is lifted. And after making the 1st slider 23 free, the roll conveyance trolley | bogie 1 moves the winding paper mounting part 100 of a rotary press to a core direction, and makes the rotary press mount the winding paper P2.

Thereafter, the roll carrier cart 1 drives the lifter 22 to lower the web support 21 and also retracts the cart 2 to return to the position of the storage rack or the tailor by receiving the next web P2.
Thus, the feeding operation of the web P2 with respect to the rotary press of the roll transport carriage 1 is completed.

Therefore, according to the above-described embodiment, the paper tube support 11 that can support the paper tube P1 having the first diameter with its core direction horizontal, and the lifter 12 that drives the paper tube support 11 to move up and down. A web support 21 that is provided at a center position different from the paper tube support 11 on the plane and can support the web P2 having a second diameter larger than the first diameter with its core direction horizontal. The roll carrier carriage 1 has a center position in the direction perpendicular to the core direction of the web P2 on the plane in accordance with the up-and-down driving of the paper tube support base 11. By adopting a configuration in which the second slider 24 is moved between a retracted position farther away from the paper tube support base 11 than the paper tube support base 11, the web paper support base 11 is supported in accordance with the up-and-down driving of the paper tube support base 11. Since 21 can be retracted by moving in the radial direction of the web P2, it is possible to prevent the vertical lifting path of the paper tube support 11 by web P2 which is supported on the web support base 21 is closed. For this reason, the paper tube support base 11 can be driven up and down in the vertical direction, the remaining core recovery can be reliably performed without being missed, and the paper tube support base 11 only needs to be moved in the vertical direction, so that the tact time can be shortened. . In addition, the paper tube support 11 and the web support 21 can be arranged close to each other on the carriage, which can contribute to downsizing the carriage. Further, there is an attached effect that the web 2 can be finely adjusted in the radial direction by the second slider 24 while the carriage 2 is stopped.
Therefore, in this embodiment, the remaining core collecting operation can be reliably performed, the tact time can be shortened, and the cart can be downsized.

  Further, in the present embodiment, by adopting a configuration in which the concave portion 8 that forms the movement path of the web supporting base 21 from the center position toward the retracted position is formed, the web supporting base 21 is formed by the concave 8. Therefore, contact with the carriage due to movement of the web support base 21 can be avoided. In addition, the web support 21 can be moved directly from the center position to the retracted position by the concave portion 8, and it is not necessary to perform a troublesome operation of retracting the web support 21 after being lifted, which can contribute to shortening the tact time.

  As mentioned above, although preferred embodiment of this invention was described referring drawings, this invention is not limited to the said embodiment. Various shapes, combinations, and the like of the constituent members shown in the above-described embodiments are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

  For example, in the above embodiment, when collecting the paper tube, the second slider 24 is driven to move the web support 21 from the center position to the retracted position, and then the paper tube support 11 is vertically moved by the lifter 12. As described above, in order to shorten the tact time of the remaining core collecting operation, the driving of the second slider 24 and the driving of the lifter 12 are started simultaneously or during the driving of the second slider 24. A configuration in which driving of the lifter 12 is started may be employed. In this case, it is preferable to control the drive of the lifter 12 based on the diameter of the web and the moving speed of the second slider 24 so that there is no interference between the web and the paper tube support 11.

For example, in the present embodiment, the second slider 24 has been described as moving the web support 21 between the center position and a retracted position set in advance based on the maximum roll diameter of the web. Is not limited to this configuration. For example, the web support 21 may support a web having a diameter smaller than the maximum roll diameter (a web that has been used halfway and finished printing, so-called middle remaining paper). It is preferable to employ a configuration that includes a detection device that detects the diameter of the web supported by 21 and a control device that controls the driving of the second slider 24 based on the detection result of the detection device. . Further, it is preferable that the control device adopts a configuration in which the position of the retracted position is set based on the diameter of the web supported by the web support 21. According to this configuration, the retracting distance of the web support 21 that can secure the vertical lifting path of the paper tube support 11 differs depending on the diameter of the web supported by the web support 21, so that, for example, the diameter of the web is small. Since the retracted position can be set close to the center position, the moving distance of the web support base 21 can be shortened. As a result, the tact time of the remaining core collecting operation can be shortened, and an energy-saving and efficient operation can be realized. The configuration of the detection device is a configuration in which a weight measuring sensor (for example, a load cell) that measures the weight of the supported web is provided on the web support 21 and the diameter of the web is calculated from the weight of the web. Alternatively, the detection result of a detector such as a laser, an infrared ray, or a camera that detects the position (height) of the web core provided on the transfer device or the tailor is received by wireless communication. The configuration may be such that the diameter of the web is calculated from the position.
Specifically, in the paper tube collecting operation of the roll transport carriage 1 in another embodiment shown in FIG. 6, the vertical lifting path of the paper tube support 11 is not blocked by the winding paper (medium remaining paper) P2. (2) The above-described paper tube collecting operation is performed by controlling the slider 24 not to be driven. In this case, in the web feeding operation shown in FIG. 7, the web 22 is lifted higher than the above-described embodiment by the lifter 22 and fed to the rotary press.

For example, although the case where the present invention is applied to AGV has been described in the above embodiment, the present invention may be applied to a tracked carriage, an overhead traveling carriage, and the like.
Further, for example, in the above-described embodiment, the roll paper is exemplified and described. However, the roll body is not limited to this configuration, and may be a winding cloth, a winding sheet, a web roll, or the like.
