The stopper 8 is lowered by the contraction action of the stopper cylinder 9 and is lowered. It will be in the permission state which permits the movement to a conveyance direction.

  Of the plurality of transport rollers 6, a predetermined number of transport rollers 6 positioned on the transport end side of the conveyor 2 are free rollers, and the remaining transport rollers 6 are drive rollers. That is, for example, as shown in FIG. 7A, the seven conveying rollers 6 (6a) on the conveying terminal side of the conveyor 2 are free rollers, and the remaining conveying rollers 6 (6b) are driving rollers.

  The cart 3 is, for example, a transport cart that can travel on the installation surface 5 in an arbitrary direction. The cart 3 includes a cart body 11 having a rectangular shape in plan view in which an opening 10 is largely formed at an intermediate portion (center portion), and casters 12 that are traveling wheels provided near four corners on the lower surface of the cart body 11. It has.

  The upper surface of the carriage main body 11 is a flat placing surface (conveyed object placing surface) 13, and the carried object W is placed on the placing surface 13. In addition, the convex part 15 is protrudingly provided by 3 sides in the mounting surface 13 of the trolley | bogie 3, and the thin disc-shaped antiskid part 16 is protrudingly provided in several places near the opening part 10 in the mounting surface 13. FIG. Has been.

  The transport device 1 includes transport means 21 for transporting the object W to be transported from the conveyor 2 in the same direction as the transport direction of the conveyor 2, and the transport means 21 with a horizontal rotation center axis (perpendicular to the transport direction of the conveyor 2 Driving means 22 that rotates in the vertical direction around the line X).

  The conveying means 21 and the driving means 22 are supported by one common base body 23 having an L shape in plan view, and the base body 23 is fixedly installed on the installation surface 5. In addition, as an example, the transfer direction of the article to be conveyed W is the same as the conveyance direction of the conveyor 2.

  The conveying means 21 is rotatably supported by a plurality of shaft support portions 24 of the base body 23 and has an axial direction perpendicular to the conveying direction of the conveyor 2 and is rotated by power from the driving means 22. 26, a support frame 27 as a pair of support members fixed to the rotation shaft 26 and facing each other, and a transported object W which is installed on both support frames 27 in the same direction as the transport direction of the conveyor 2 And a free roller 28 which is a conveying roller as a plurality of rotating bodies.

  Note that a non-drive type conveyance unit 30 is configured by the plurality of (for example, three) free rollers 28. Note that the two shaft support portions 24 fix the rotation shaft 26 to the base body 23 so as to sandwich the transport portion 30 of the transport means 21 therebetween. Further, the two shaft support portions 24 fix the rotating shaft 26 to the base body 23 so as to sandwich the connecting arm 37 therebetween. The rotating shaft 26 is supported and fixed to the base body 23 by at least these three shaft support portions 24.

  Each free roller 28 includes a roller shaft 31 provided on both support frames 27, and a cylindrical roller body 32 rotatably supported by the roller shaft 31. Further, the two support frames 27 that are spaced apart from each other are connected to each other by a plurality of connecting rods 33.

  The drive means 22 includes a cylinder (for example, an air cylinder) 36 that is an extendable drive source, and a connecting arm 37 that connects the cylinder 36 and the rotation shaft 26. The cylinder 36 has a cylinder body 38 and a rod 39 that enters and exits the cylinder body 38 so that the base end portion of the cylinder body 38 is rotatable to the cylinder mounting portion 40 of the base body 23. The tip of the rod 39 is attached to the tip of the connecting arm 37 so as to be rotatable.

  When the cylinder 36 performs the extending operation, the connecting arm 37 is pushed out in conjunction with this and the rotating shaft 26 rotates in one direction, so that the conveying means 21 rotates based on the extending operation of the cylinder 36. By rotating upward about the moving shaft 26, at least a part of the transport unit 30, that is, for example, only the upper end portions of the plurality of free rollers 28 are located above the mounting surface 13 of the cart 3 from the opening 10 of the cart 3. It will be in the 1st state which protrudes (refer to Drawing 6 (a)).

  That is, the transport unit 21 is in a first state in which the transport unit 30 projects upward from the placement surface 13 of the carriage 3 by the upward rotation based on the operation of the driving unit 22.

  In this first state, the upward projecting dimension A of the transport unit 30 with respect to the mounting surface 13 is larger than the upward projecting dimension B of the anti-slip unit 16 with respect to the mounting surface 13. In other words, the gap dimension (for example, about 5 mm) between the mounting surface 13 of the carriage 3 and the upper end of the free roller 28 is larger than the thickness dimension of the anti-slip portion 16 of the carriage 3.

  In this first state, the upper ends of the plurality of free rollers 28 (conveying surfaces of the conveying unit 30) are located above the placement surface 13 of the carriage 3 and the plurality of conveying rollers 6 of the conveyor 2 are disposed. Is located on the same plane (including substantially the same plane) as the upper end (conveying surface of the conveyor 2). At this time, a portion of each free roller 28 excluding the upper end is accommodated in the opening 10 of the carriage 3.

  On the other hand, when the cylinder 36 is contracted, the connecting arm 37 is pulled back in conjunction with this, and the rotation shaft 26 rotates in the other direction opposite to the one direction. As a result of the downward rotation about the rotation shaft 26 based on the contraction operation of the carriage 3, all of the transport section 30, that is, for example, the whole of the plurality of free rollers 28, goes out from the opening 10 of the carriage 3 and travels on the carriage 3. The second state in which (move) is allowed (see FIG. 6B).

  That is, the transport unit 21 enters a second state in which the transport unit 30 does not protrude upward from the placement surface 13 of the carriage 3 due to the downward rotation based on the operation of the drive unit 22.

  In the second state, the upper end of the most upstream free roller 28 among the plurality of free rollers 28 is positioned below the lower surface 11 a of the carriage body 11 of the carriage 3. The lower end of the most downstream free roller 28 among the plurality of free rollers 28 is located above the installation surface 5, and the free roller 28 does not contact the installation surface 5 (therefore, the installation surface 5 There is no need to provide a recess on the surface).

  In this way, the transport means 21 can be selectively switched between the first state and the second state by the vertical rotation based on the operation of the drive means 22 by using the opening 10 of the carriage 3. Then, when the transport means 21 switches from the first state to the second state, the article W to be transported on the transport unit 30 is slightly lowered and placed on the placement surface 13 of the carriage 3. .

  Moreover, the conveyance apparatus 1 contact | abuts one side surface (insertion direction front surface of the trolley | bogie 3) along the direction parallel to the conveyance direction (replacement direction) of the conveyor 2 among the four side surfaces which the rectangular trolley | bogie 3 has. An elongated plate-like first positioning body 41 and another side surface orthogonal to one side surface of the carriage 3 at a predetermined distance from the conveying terminal end of the conveyor 2 (the side 15 in the insertion direction of the carriage 3 and the convex portion 15 is provided). And an elongated plate-like second positioning body 42 in contact with the side surface on the existing side.

  And the area | region where three directions were enclosed by the end plate 2a of the conveyance termination | terminus part of the conveyor 2 which is the edge part (replacement direction edge part) of the 1st mounting part, the 1st positioning body 41, and the 2nd positioning body 42 However, it is a cart insertion region (inner region) 43 that is open only in the remaining one direction, and the cart 3 is inserted into the cart insertion region 43 so as to be removable. The insertion direction and the removal direction of the carriage 3 with respect to the carriage insertion region 43 are directions orthogonal to the conveyance direction of the conveyor 2.

  As is clear from FIG. 1, a part of the rotation shaft 26 of the conveying means 21, the support frame 27 and the free roller 28 are located in the carriage insertion region 43 in plan view. And the drive means 22 are located outside the carriage insertion region 43 and on the first positioning body 41 side in plan view, specifically, located near the outside of the first positioning body 41. The drive means 22 is the first positioning body. The body 41 and the longitudinal direction (also the expansion / contraction direction of the cylinder rod) face the same direction. The other part of the rotating shaft 26 and the driving means 22 located outside the cart insertion area 43 are covered with a box-shaped cover body 44.

  Here, the first positioning body 41 is composed of a plate-like member having a longitudinal direction in a direction parallel to the conveying direction of the conveyor 2, and an installation plate portion 46 fixedly installed on the installation surface 5, and this installation And a positioning plate portion 47 erected on the plate portion 46. Further, the first positioning body 41 is formed with a notch 48, and the rotation shaft 26 and the base body 23 are inserted into the notch 48.

  The second positioning body 42 is composed of a plate-like member having a longitudinal direction in a direction orthogonal to the transport direction of the conveyor 2, and an installation plate portion 51 fixedly installed on the installation surface 5, and the installation plate It has a positioning plate portion 52 erected on the portion 51 and an inclined guide plate portion 53 provided continuously with the positioning plate portion 52. The guide plate portion 53 guides the carriage 3 toward the carriage insertion area 43 when the carriage 3 is inserted into the carriage insertion area 43.

  Next, a case where the transported object 1 is transferred from the conveyor 2 to the carriage 3 using the transport apparatus 1 will be described.

  First, as shown in FIG. 7A, the transported object W is moved in the transport direction by the transport rollers 6 of the conveyor 2 in a state where the empty cart 3 travels in the insertion direction and is inserted into the cart insertion area 43. Be transported.

  Next, as shown in FIG. 7B, when the conveyed object W comes into contact with the stopper 8 and stops at a predetermined position, the operator operates a predetermined button (not shown).

  Then, as shown in FIG. 7C, the conveying means 21 is rotated upward based on the operation of the driving means 22 to be in the first state (advanced state). As a result, the upper end portion of each free roller 28 is moved to the carriage. 3 protrudes upward from the mounting surface 13. Further, the stopper 8 is lowered to enter a permissible state in which movement of the article W to be conveyed is permitted.

  And in this state, an operator pushes the to-be-conveyed object W on the conveyor 2 by hand, and moves it to a conveyance direction.

  Then, as shown in FIG. 8D to FIG. 9G, the object W is conveyed by the conveying roller (free roller) 6 of the conveyor 2 and the free roller 28 of the conveying means 21. The sheet is conveyed in the conveying direction until the lower end of the front surface in the conveying direction comes into contact with the convex portion 15 of the carriage 3.

  At this time, the lower surface (bottom surface) of the conveyed object W is supported by the free roller 28 and moves in the vicinity of the upper surface of the mounting surface 13 of the carriage 3, but does not contact the anti-slip portion 16 on the mounting surface 13. (Sliding contact) does not.

  Here, as shown in FIG. 8D, in the state where the transport direction front end of the transported object W is placed on the most upstream free roller 28 among the plurality of free rollers 28, the center of gravity G of the transported object W is , Located above the conveyor 2. For the sake of explanation, the center of the rectangle in the side view of the conveyed object W is considered as the position corresponding to the center of gravity.

  Thereafter, the center of gravity G is located above the conveyor 2 and the conveying means 21 as shown in FIG. 8E, and the center of gravity G is located above the upstream side of the conveying means 21 as shown in FIG. After the state, the conveyed object W comes into contact with the convex portion 15 of the carriage 3 in a state where the center of gravity G is positioned above the most downstream free roller 28 among the plurality of free rollers 28 as shown in FIG. Stop. The separation distance between the position of the most upstream free roller 28 that is the most upstream position of the conveying unit 30 and the most downstream free roller 28 of the conveyor 2 that is the most downstream position of the first conveying unit is the length in the conveying direction of the object to be conveyed. It is shorter than 1/2 of the (replacement direction length).

  Since the object W is thus transferred from the conveyor 2 onto the conveying means 21, the front side of the object W is positioned on the free roller 28 before the center of gravity G is detached from the conveyor 2. Is moved from the conveyor 2 to the free roller 28, the front side and the rear side of the conveyed object W are supported, and the inclination of the conveyed object W is prevented. In addition, since the center of gravity G is always located on the free roller 28 after the transfer onto the conveying means 21, the conveyed object W is prevented from being inclined.

  In the state shown in FIG. 9G, the center of gravity G of the conveyed object W is located above the most downstream free roller 28. At this time, the most downstream free roller 28 is located at the center of the carriage 3. Therefore, the center of gravity G of the conveyed object W is also located at the center of the carriage 3.

  In this state, when the operator operates a predetermined button (not shown), as shown in FIG. 9 (h), the conveying means 21 rotates downward based on the operation of the driving means 22, and the cart 3 As a result, each free roller 28 is retracted from the opening 10 of the carriage 3 and is disposed between the lower surface 11a of the carriage body 11 and the installation surface 5.

  At this time, the article W to be conveyed on the free roller 28 of the conveying means 21 is slightly lowered and placed on the placing surface 13 of the carriage 3 with its center of gravity G coinciding with the center of the carriage 3.

  Next, as shown in FIG. 9 (i), the operator moves the carriage 3 on which the article to be conveyed W is placed in the take-out direction so that it is taken out from the carriage insertion area 43, and is then used with the carriage 3. The transported object W is transported to a predetermined place.

  And according to such a conveying apparatus 1, since it has the conveying means 21 which can be rotated up and down, and the drive means 22 which rotates this up and down, while being able to reduce a burden on an operator, the to-be-conveyed object W is conveyed. It is possible to transfer from 2 to the carriage 3 appropriately and stably, it is possible to appropriately cope with an increase in the weight of the transported object W, and it is safe because the transported object W does not tilt during the transfer.

  Further, the other part of the rotation shaft 26 having the axial direction in the direction orthogonal to the conveying direction of the conveyor 2 and the driving means 22 are located outside the carriage insertion region 43 and in the vicinity of the first positioning body 41 in plan view. The drive means 22 does not interfere with the insertion and removal of the carriage 3 from the carriage insertion area 43, and the carriage 3 does not interfere with the drive means 22.

  Further, the rotation center axis X of the rotation shaft 26 intersects (orthogonally) the transfer direction that is the conveying direction of the conveyor 2, and the carriage 3 is in the direction of the rotation center axis with respect to the carriage insertion region 43. Therefore, even if the rotating shaft 26 is installed on the same plane as the traveling surface (moving surface) of the caster 12, the caster 12 does not interfere with the rotating shaft 26 when moving. The carriage 3 can be safely inserted and removed from the carriage insertion area 43. In addition, since the shaft support portion 24 for fixing the rotation shaft 26 to the installation surface 5 is provided at a position sandwiching the conveyance portion 30 of the conveyance means 21, the rotation shaft 26 is more firmly fixed to the base body 23. can do.

  Further, since the connecting arm 37 and the driving means 22 are arranged outside the carriage insertion region 43 and on the first positioning body 41 side, the connecting arm 37 does not interfere with other objects, and the rotating shaft 26 is sufficiently rotated. An angle can be secured.

  Further, since the conveying means 21 and the driving means 22 are supported by a single common base body 23, the apparatus can be made compact and installation work is also easy without requiring on-site assembly.

  Further, when the conveying means 21 is in the first state, the protruding dimension A of the conveying unit 30 with respect to the mounting surface 13 is larger than the protruding dimension B of the anti-slip unit 16 with respect to the mounting surface 13, so When the article W is conveyed, the lower surface of the article W to be conveyed does not come into contact with the anti-slip portion 16, and the operator can easily and smoothly move the article W to be conveyed in the same direction as the conveying direction of the conveyor 2. .

  Note that the transport means 21 of the transport apparatus 1 may be configured as shown in FIG. 10, for example, in order to further stably transport the article W to be transported.

  The transport means 21 shown in FIG. 10 has a rotating frame 61 as a second support body that is attached to a support frame 27 as a first support body so as to be rotatable in the vertical direction about a support shaft portion 60. The rotating frame 61 is also provided with a plurality of, for example, two free rollers 28. For this reason, in the example shown in FIG. 10, the conveying unit 30 is constituted by five free rollers 28 more than those shown in FIG. The support frame 27 is provided with three first free rollers 28 as the first transport unit, and the rotating frame 61 is provided with two first free rollers 28 as the second transport unit. A continuous conveyance surface is formed by these five free rollers.

  Further, the support frame 27 is a stopper as a restricting body that allows the support frame 27 of the rotation frame 61 to rotate upward and restricts downward rotation by engagement with the recess 62 of the rotation frame 61. A portion 63 is projected.

  In the first state of the conveying means 21 shown in FIG. 10A, the downward rotation of the rotating frame 61 is restricted by the stopper portion 63, so that the five free rollers 28 are at the same height position. Only the upper end portion of each free roller 28 is located so as to protrude above the mounting surface 13 of the carriage 3.

  When the support frame 27 rotates together with the rotation shaft 26 from this state, both the support frame 27 and the rotation frame 61 rotate around the rotation shaft 26, and when the support frame 27 rotates by a predetermined angle, the most downstream free roller 28 rotates. After the contact with the installation surface 5, the support frame 27 rotates about the rotation shaft 26, and the rotation frame 61 rotates relative to the support frame 27, so that FIG. It will be in the state shown in Therefore, since the support frame 27 rotates to a predetermined position, the most upstream free roller 28 also comes out of the opening 10 of the carriage 3, and the upper end of the most upstream free roller 28 is from the lower surface 11 a of the carriage body 11. Is also located below. Therefore, the conveying means 21 is in the second state in which the carriage 3 is allowed to travel, and the carriage 3 can be taken out from the carriage insertion region 43 by moving in the removal direction.

  Moreover, although the conveying apparatus 1 demonstrated as what was used when the to-be-conveyed object W was transferred from the conveyor 2 to the trolley | bogie 3 in the said embodiment, the to-be-conveyed object W is transferred from the trolley | bogie 3 to the conveyor 2. The first placement unit is not limited to the conveyor 2 and may be a stage (stage) or the like. Therefore, in the embodiment, since the transfer of the transported object W is performed in the transport direction at the downstream end of the conveyor 2, the transport direction of the conveyor 2 is the transfer direction. However, the present invention is not limited to this, and any direction in which the object to be transported moves between the first placement unit and the second placement unit can be set as the replacement direction.

  Furthermore, the transport unit 30 of the transport means 21 is not limited to a non-drive type composed of free rollers, and may be a drive type composed of drive rollers, for example.

  In addition, the transport unit 30 may be configured by a belt, a roller, a ball, or the like instead of the transport roller, and the cart 3 is not limited to the dolly cart, and various carts such as a cart cart can be adopted.

  Further, the first positioning body 41 and the second positioning body 42 may be integrated with each other, for example, or may be provided integrally with the base body 23, or from a plurality of members positioned at intervals. It may be formed.

  Further, the support may be combined not only with a pair of frames that support the free roller, but also with a frame to which the free roller is fixed and a frame that further supports the frame.

  Furthermore, the transported object W, which is a transfer object, is not limited to a container group (article group) in which a plurality of containers are stacked. For example, one article may be used, and the type of the article is not limited. Absent.
