Here, four casters 22 and 23 are provided, but the number of casters is arbitrary.

  Further, the transport mechanism 20 is provided with a handle portion 60 facing upward on the rear side of the bottom plate 21 with respect to the transport direction (α direction) of the transport carriage 10. The carrier 60 is moved in the transport direction by being pushed in the transport direction while being gripped by an operator. In this way, the stacking table 50 on which the prepreg sheets P are stacked is conveyed toward the supply device 100. As shown in FIG. 7, the handle portion 60 has its upper portion further bent toward the rear side in the transport direction, so that the operator can easily push it.

  As shown in FIGS. 5 and 7, two vertical members 60 a and 60 b of the handle portion 60 are provided with plate-shaped mounting portions 61 for horizontally mounting the lock member 70. The mounting portion 61 is a member to which the rear end (the other end) of the lock member 70 in the transport direction is hooked from above, and is an example of a third mounting portion.

  The lift table 30 is mounted on the bottom plate 21 of the transport mechanism 20, and the roller row 40 is mounted on the top thereof. A plate-shaped member 32 is fixed to the bottom plate 21, and the plate-shaped member 31 of the elevating table 30 can be moved up and down to elevate the placed loading table 50.

  The roller row 40 is a plurality of rollers rotatably mounted on the upper part of the plate-shaped member 31 of the elevating table 30, and is an example of a moving mechanism. The roller row 40 rotates to slide the loading table 50 placed on the upper portion. Specifically, the roller row 40 slides the loading platform 50 in the α direction by rotating in the arrow R2 direction, and rotates the loading platform 50 in the direction opposite to the arrow R2 direction by rotating the loading platform 50 in the direction opposite to the α direction. Slide to move. Although the roller row 40 of the present embodiment has four rollers, any number of rollers can be provided.

  In the present embodiment, the roller row 40 moves the loading platform 50 to a predetermined position by rotating in the direction opposite to the arrow R2 direction when the loading platform 50 is placed on the transport vehicle 10. Further, when the carriage 10 is conveyed to the supply device 100, the roller row 40 rotates in the direction of arrow R2 to move the stacking base 50 on which the prepreg sheets P are stacked to a predetermined position of the supply device 100.

  The stacking table 50 has a rectangular surface on which the prepreg sheets P are stacked. Further, the loading platform 50 is provided with a U-shaped mounting portion 51 for mounting the lock member 70 on the rear side with respect to the transport direction of the transport vehicle 10. In the present embodiment, the mounting portion 51 is provided on the side surface that is the rear side of the loading platform 50 to form the opening 51a (see FIGS. 4 and 5). The mounting portion 51 is a member to which the front end portion (one end portion) of the lock member 70 in the transport direction is inserted into the opening portion 51a from above, and is an example of the second mounting portion.

  The lock member 70 fixes the loading platform 50 and the handle 60 on the rear side of the transport vehicle 10, and is an example of a securing member. Specifically, the lock member 70 has a U-shape, and as shown in FIG. 6, when the lock member 70 is lowered in a direction in which the lower part is opened (from the upper side to the lower side (β direction)), one end of the lock member 70 is lowered. The unit is attached to the loading platform 50 by being inserted into and hanging from the opening 51a of the U-shaped mounting unit 51 provided on the loading platform 50. Further, the lock member 70 is attached to the handle portion 60 by hooking the other end portion thereof to a plate-shaped attachment portion 61 provided horizontally on the handle portion 60. As a result, the lock member 70 fixes the loading platform 50 and the handle portion 60. Further, the lock member 70 is removed from the mounting portion 51 and the mounting portion 61 by lifting in the upward direction (the direction opposite to the β direction) from the lower side, and the fixing between the loading platform 50 and the handle portion 60 is released. To do.

  The bracket 80 holds the prepreg sheets P stacked on the stacking table 50 in a stacked state to prevent the prepreg sheets P from collapsing or falling, and is an example of a holding member. As shown in FIGS. 4 and 6, the bracket 80 is detachably provided on the loading table 50.

  FIG. 7 shows the loading platform 50 mounted on the cart 15 and the bracket 80 mounted on the loading platform 50. 8 and 9 are perspective views when a bracket is attached to a corner of the loading table. FIG. 8 is a diagram when viewed from the rear upper right diagonal direction when facing the transport direction of the transport vehicle 10. FIG. 9 is a diagram when viewed from the rear left obliquely upper direction when the transport vehicle 10 faces the transport direction.

  As shown in FIGS. 7 to 9, the bracket 80 is a plate-shaped member having an L-shaped cross section, is attached to a corner portion of the stacking table 50, and abuts on a corner portion of the prepreg sheet P, thereby making the prepreg sheet P. This holds the P loading state. The bracket 80 can also be used for positioning when the prepreg sheets P are stacked on the stacking table 50. That is, when the corner of the prepreg sheet P is brought into contact with the L-shaped corner of the bracket 80, the prepreg sheet P of any size is positioned with the corner as a reference.

  As shown in FIG. 7, the bracket 80 is attached to the loading table 50 by four knobs 81a, 81b, 81c, 81d that are connection members. The knobs 81a to 81d are inserted into the loading platform 50 through the holes formed in the bracket 80, and are connected to the loading platform 50 by rotating in the predetermined first direction, so that the bracket 80 is loaded into the loading platform 50. Be attached to. Further, by rotating the knobs 81a to 81d in the second direction opposite to the first direction, the knobs 81a to 81d are released from the loading platform 50, and the bracket 80 is removed from the loading platform 50.

  Next, a flow of work until the prepreg sheet P is transported (transported) to the supply device 100 by the transport carriage 10 will be described. FIG. 10 is a diagram showing a state where the stacked prepreg sheets are being conveyed to the supply device by the conveyance carriage.

  First, the supply device 100 acquires the sheet information of the conveyed prepreg sheet P. The sheet information is information related to the prepreg sheet P such as the size (vertical and horizontal dimensions) of the prepreg sheet P. For example, this sheet information is embedded in a card as a bar code, and when the prepreg sheet P is conveyed, the supply device 100 first reads and acquires the card. Further, the supply device 100 may acquire the sheet information by the operator inputting the sheet information. The size (vertical and horizontal dimensions) of the prepreg sheet P is used, for example, when the prepreg sheet P is moved to the supply device 100 and when the prepreg sheet P is aligned with the supply device 100.

  Then, the supply device 100 sets the lifter table to a predetermined initial position by using the elevator 120 (see FIG. 2). The lifter table is a table on which the prepreg sheet P provided on the supply device 100 is placed. As shown in FIG. 10, on the lifter table, a bottom plate 140 on which the loading table 50 on which the prepreg sheets P are loaded and a loading table 50 that has been moved by the roller array 40 are slidably moved to a predetermined position. Are provided and are lifted and lowered by the elevator 120.

  The work of setting the position of the lifter table may be performed manually by an operator operating the elevator 120, or may be configured to be performed by the supply device 100 controlling the elevator 120. Further, the roller row 141 of the present embodiment has a configuration in which four rollers are provided, but an arbitrary number of rollers can be provided.

  Next, on the side of the carriage 10, the bracket 80 is mounted on the stacking table 50, and the prepreg sheets P are stacked on the stacking table 50. At this time, by aligning one corner of the prepreg sheet P with the corner of the bracket 80, the prepreg sheet P is positioned for stacking. The prepreg sheets P may be stacked manually by an operator or may be configured by an external device.

  Then, the stacking table 50 on which the prepreg sheets P are stacked is placed on the roller row 40. Specifically, the end of the stack 50 on which the prepreg sheet P is placed is placed on the roller row 40 and pushed to rotate the roller row 40 in the direction opposite to the arrow R2 direction (see FIG. 4), and 50 slides in the direction opposite to the α direction. The loading platform 50 is placed by an external device such as a forklift.

  For example, in the carrier 10 of the present embodiment, since the lower limit of the height h1 from the floor surface to the roller row 40 is 500 mm, the height from the floor surface of the lifter table of the supply device 100 to the roller row 141. Can be adjusted to the same level as long as it is 500 mm or more. Further, for example, by raising the height of the lifter table to about 800 mm, workability can be improved.

  After that, the lock member 70 is lowered from above, and the lock member 70 is mounted on the mounting portion 51 of the loading platform 50 and the mounting portion 61 of the handle portion 60 to lock the loading platform 50 and the transport mechanism 20 provided with the handle portion 60. It is fixed by the member 70.

  Here, in the work flow described above, the prepreg sheets P are stacked on the stacking table 50, and then the stacking table 50 is mounted on the carriage unit 15. However, the work may be performed in the reverse order. . Specifically, for example, first, the loading table 50 on which the prepreg sheets P are not loaded is slid by the roller row 40 and placed on the cart unit 15, and the loading member 50 and the handle section 60 are provided by the lock member 70. The transport mechanism 20 thus fixed is fixed. Then, the bracket 80 is mounted on the stacking table 50 and the prepreg sheets P are stacked. The work may be performed in this order.

  Return to work flow. Next, when the operator pushes the handle 60 in the transport direction (α direction), the transport carriage 10 on which the stacking base 50 on which the prepreg sheets P are stacked is placed is moved in the transport direction, and the transport carriage 10 is supplied to the supply device. It is conveyed to a predetermined stop position near 100.

  Next, the bracket 80 is removed from the loading platform 50, and the lock member 70 is lifted and removed from the mounting portions 51 and 61 to release the fixation of the loading platform 50 and the transport mechanism 20 provided with the handle portion 60. .

  Then, the loading platform 50 on which the prepreg sheets P are loaded is slid from the cart unit 15 to the lifter table of the supply device 100. Specifically, the height of the roller row 40 of the transport carriage 10 is adjusted by the lifting platform 30 so as to match the height of the roller row 141 of the supply device 100. After that, the stack table 50 on which the prepreg sheets P are stacked is pushed in the α direction, whereby the roller row 40 and the roller row 141 rotate in the arrow R2 direction (see FIG. 4), and the stack table 50 slides in the α direction. Then, the carriage 10 moves to the supply device 100.

  After that, the stacking table 50 is aligned with the center position of the supply device 100 and the center position of the prepreg sheet P using the sheet information acquired first. The details of this alignment will be described later. Then, the supply device 100 raises the lifter table to a position where the prepreg sheet P can be supplied to the conveyance device 200 and sequentially supplies the prepreg sheet P to the conveyance device 200.

  Next, the positioning of the stacking base 50 performed when the stacking base 50 on which the prepreg sheets P are stacked on the supply device 100 is slid (the center position of the supply device 100 is aligned with the center position of the prepreg sheet P). Will be described.

  In order to float and separate the prepreg sheets P loaded on the loading platform 50 by the air jet nozzle unit 400 (floating separation unit), the supply device 100 and the loading platform 50 must be aligned. That is, as described above, the air jet nozzle unit 400 floats and separates the prepreg sheet P by blowing air toward a predetermined position on the front end portion of the prepreg sheet P stacked on the stacking table 50. Therefore, when the stacking table 50 is conveyed to the supplying device 100, the stacking table 50 and the supplying device 100 must be aligned so that the air is blown to the predetermined position of the prepreg sheet P.

  However, if the supply device 100 and the stacking table 50 cannot be aligned with each other, air is blown to a position different from the predetermined position of the front end portion of the prepreg sheet P stacked on the stacking table 50. Then, the prepreg sheet P does not float and cannot be separated, and non-feeding or double feeding occurs.

  Hereinafter, the flow of alignment between the supply device 100 and the loading platform 50 will be described with reference to FIGS. FIG. 11 is a diagram showing a state before the loading platform is moved from the transport vehicle to the supply device. FIG. 12 is a diagram showing a state in which the loading platform has begun to be moved from the transport vehicle to the supply device. FIG. 13 is a diagram showing a state in which the loading platform is moved from the transport vehicle to the supply device. FIG. 14 is a diagram showing a state in which the position of the supply device and the position of the loading platform are adjusted. 11 to 14 are conceptual diagrams when viewed from above the supply device.

  As shown in FIG. 11, a bottom plate 140, a roller array 141, guides 142 and 143, and an elevator 120 are provided on the supply device 100 side.

  As described above, the bottom plate 140 is a plate-shaped base on which the stacking base 50 on which the prepreg sheets P are stacked is moved and placed, and is provided inside the side plates 151 and 152 of the supply device 100. .

  The roller row 141 is a plurality of rollers rotatably mounted on the upper portion of the bottom plate 140, and rotates to slide the loading table 50 placed on the upper portion. Specifically, like the roller row 40, the roller row 141 rotates in the arrow R2 direction (see FIG. 4) to slide the loading table 50 in the α direction, and rotates in the direction opposite to the arrow R2 direction. This causes the loading platform 50 to slide in the direction opposite to the α direction.

  The guides 142 and 143 are arranged so that when the loading table 50 is moved on the roller row 141, the loading table 50 can move along the carrying direction of the roller row 141 without deviating from the carrying direction or rotating. It is a member to guide. The guides 142 and 143 are provided outside both ends of the roller row 141 along the transport direction, and the rear side in the transport direction is opened in the direction opposite to the transport direction and has a V-shape. This facilitates insertion of the front side of the loading platform 50 when moving the loading platform 50 to the roller row 141 of the bottom plate 140.

  The lift 120 lifts and lowers the lifter table to a desired position, and the bottom plate 140 and the roller row 141 are placed on the adjustment stands 121 and 122 provided in a direction perpendicular to the transport direction (α direction). ing. Further, the adjustment stands 121 and 122 extend in a direction perpendicular to the carrying direction, and the bottom plate 140 on which the loading stand 50 is placed moves along the adjusting stands 121 and 122 to be perpendicular to the carrying direction. It can be moved in any direction.

  The reference position C0 in FIG. 11 is the center position (center position) with respect to the supply device 100. The reference position C0 is a reference line for moving the prepreg sheet P to a position where it can float, and is a reference line for aligning the center position of the prepreg sheet P conveyed from the conveyance carriage 10. Therefore, by moving the stacking table 50 so that the center position of the prepreg sheet P is aligned with the reference position C0, the stacked prepreg sheets P can be floated by the air jet nozzle unit 400 (see FIG. 3) that is a floating separation unit. That is, the loading platform 50 is adjusted according to the predetermined position.

  On the stacking table 50, even if the maximum size prepreg sheet P20 that can be transported is stacked or the minimum size prepreg sheet P10 is stacked, the corner portion of the bracket 80 is brought into contact with the corner portion of the prepreg sheet P and positioned. To be done. Therefore, when the prepreg sheet P is positioned by the bracket 80, the center position in the width direction (direction perpendicular to the transport direction) varies depending on the length of the prepreg sheet P in the width direction. Here, a case where the stacking table 50 on which the prepreg sheets P10 having the minimum size are stacked is moved will be described. The center position of the prepreg sheet P10 in the width direction is C10.

  When the stacking table 50 on which the prepreg sheets P10 are stacked is moved to the supply device 100, as shown in FIG. 12, the stacking table 50 is pushed along the guides 142 and 143 to move it from the transport carriage 10. At this time, the reference position C0 of the supply device 100 and the center position C10 of the prepreg sheet P10 have not yet been aligned, and thus are displaced.

  Next, when the loading platform 50 is moved to a predetermined position of the feeding device 100 (see FIG. 13), the loading platform 50 is adjusted in order to match the reference position C0 of the feeding device 100 and the center position C10 of the prepreg sheet P10. It is adjusted by moving it in the width direction along the stands 121 and 122. Then, as shown in FIG. 14, the stacking table 50 is stopped at a position where the reference position C0 of the supply device 100 and the center position C10 of the prepreg sheet P10 match.

  Here, a method of aligning the reference position C0 of the supply device 100 and the center position C10 of the prepreg sheet P10 will be described. The reference position C0 of the supply device 100 and the center position of the prepreg sheet P10 are aligned by, for example, a sensor using laser light or the like and a reflector.

  As described above, when the loading platform 50 on which the prepreg sheets P10 are loaded is transported by the transport vehicle 10, the supply device 100 acquires the sheet information.
