Description

  The present invention relates to a conveyor that sorts or merges lightly transported objects.

  2. Description of the Related Art Conventionally, there is known a sorting conveyor technique in which one end of a belt conveyor is shaken to the left and right of a horizontal plane for merging and branching in order to sort and merge conveyed objects in the horizontal direction (see, for example, Patent Document 1).

  However, in this type of conveyor, a head-and-tail pulley for stretching a conveyor belt is pivotally supported on the distribution conveyor frame on one end side that is swung to the left and right. When merging and branching, the head-and-tail pulley on one end orthogonal to the conveyor frame moves in an arc. In order to prevent interference between the fan-shaped circular arcs formed by both ends of the head-tail pulley on one end side and the rotation center, the head-tail pulley of the carry-in conveyor in the case of merging or the carry-out conveyor in the case of sorting, It was necessary to make a gap with the head-and-tail pulley, and this gap was large, and it was difficult to transfer with a small transported object.

  Therefore, for example, in a sorting conveyor in which a grooved tail roller is pivotally supported at both ends in the machine length direction of the conveyor frame and a plurality of round belts are wound around the groove of the grooved tail roller in parallel to form a conveying surface, the conveyor frame When the other end is swung horizontally with the other end in the machine length direction as a fulcrum, the quadrangle formed by the conveyor frame and the grooved tail roller is transformed into a parallelogram in plan view. A technique has been proposed in which the roller axis is maintained in parallel and is maintained in equilibrium with the edges of the carry-in or carry-out conveyors disposed before and after the sorting conveyor (see, for example, Patent Document 2).

  In this sorting conveyor, the grooved tail roller is formed with a predetermined number of grooves corresponding to the number of round belts wound in parallel on the outer peripheral surface of a metal or resin straight roller. The shape of the groove is formed in an arc drum shape so that a parallel interval can be maintained even when a round belt having a substantially circular cross section follows the deformation of the conveyor frame into a parallelogram and tilts parallel to the frame. . A predetermined number of grooves are continuously formed along the axial direction.

However, in the sorting conveyor of Patent Document 2, for example, as shown in FIG. 20, the quadrangle formed by the conveyor frame 200 and the grooved tail roller is configured as a parallelogram. The two grooved tail roller shaft centers approach each other when the quadrilateral is inclined.
That is, when the conveyor frame 200 is shaken, for example, a gap is generated between the end edge of the carry-out conveyor 201 and the grooved tail roller. Moreover, the larger the distribution angle of the conveyor frame 200 is, the larger the gap 202 becomes. When a small transported object is transported, the transported object may fall from the clearance 202 or may greatly bounce and jump out of the transport surface. there were. For this reason, there is a problem in that it cannot be transported unless the transported object is larger than the gap 202.

Moreover, in the sorting conveyor of Patent Document 2, for example, as shown in FIG. 20, when the sorting angle of the conveyor frame is increased, each round belt is held in the groove of the grooved tail roller, and the initial parallel winding state is obtained. There is a risk that the endless rotation cannot be maintained, and the conveyance surface may be lost due to being removed from the groove.
Therefore, in the distribution conveyor of Patent Document 2, it is necessary to keep the distribution angle of the conveyor frame small.

For example, as shown in FIG. 14, the connecting member 131 that connects the opposing fork portions 117 d has a center portion that is notched to prevent buffering with the slide rail 91 of the length adjusting mechanism 89.
Fork part 117e is set to be higher than fork part 117d, for example, as shown in FIG. Then, in order to support the shaft 125a of the fourth return roller 125 at the front end portion, a recess 117e1 that opens in the fork portion 111d direction and has a locking piece 117e2 at the opening end is provided. The shaft 125a of the fourth return roller 125 is processed to have a D-shaped cross section, and is disposed so that the linear portion comes into contact with the concave portion 117e1 on the tip end side. In the recess 117e1, a fixture 117e3 for supporting the shaft 125a of the fourth return roller 125 is fixed to the lower portion of the recess 117e1 via a screw 117e4. The shaft 125a of the fourth return roller 125 is constrained not to rotate by the inner wall surface of the recess 117e1, the locking piece 117e2, and the fixture 117e3. The fourth return roller 125 has a built-in bearing so that the outer periphery of the roller is rotatable. The fork part 117e is provided with a hole 117e6 for fixing a connecting member 135 for connecting the opposing fork part 117e with a nut 117e5.

For example, as shown in FIG. 13, the L-shaped take-up plate 133 includes an L-shaped bracket 133a and a seat portion 133b that is connected to the lower portion of the L-shaped bracket 133a. The L-shaped bracket 133a is provided with a recess 133a2 that opens to the first return roller 123 side on the rising wall 133a1 and supports the shaft portion 127a of the second return roller 127. The shaft portion 127a of the second return roller 127 is processed into a D-shaped cross section so that it does not rotate within the recess 133a2.

The L-shaped bracket 133a is provided with a recess 133a4 for supporting the shaft 129a of the third return roller 129 on the upper surface side of the laterally extending wall 133a3 by cutting out the top side. The shaft portion 129a of the third return roller 129 is processed to have a D-shaped cross section so that it does not rotate in the recess 133a4. The third return roller 129 has a built-in bearing so that the outer periphery of the roller is rotatable.

The round belt 75 forming the conveyance surface is brought into contact with the first return roller 123 and the third return roller 129 at one of the conveyance surface and the back surface forming the top and bottom, and the upper and lower conveyance surfaces of the round belt 75 The take-up unit 111 and the round belt 75 are arranged so that one of the other surfaces comes into contact with the second return roller 127 and the fourth return roller 125.
The seat 133b of the L-shaped bracket 133 is provided with a hole 133b1 through which the screw 130 is inserted.
For example, as shown in FIG. 2, when the cam follower 109 is positioned at the top 105 a of the cam rail 105, take-up is performed so that a constant tension is applied to the round belt 75 in order to secure a conveying force by the round belt 75. When the unit 111 is rotated and the cam follower 109 comes to the top 105a of the cam rail 105, the distance between the first return roller 123 and the second return roller 127 is narrowed, and the round belt 75 wound around is folded, and The fourth return roller 125 also comes into strong contact with the round belt 75 so as to bend the round belt 75, so that the round belt 75 can be prevented from loosening due to the approaching horizontal distance between the idler pulley 25 and the idler pulley 49.

For example, as shown in FIG. 13, when the cam follower 109 is positioned on the side portion 105b of the cam rail 105, in order to secure the conveying force by the round belt 75, the tension on the round belt 75 is made constant. The heights of the one return roller 123, the second return roller 127, the third return roller 129, and the fourth return roller 125 are all different, the fourth return roller 125 being the highest, and the second return roller 127, the first return roller 123. The third return roller 129 is lower in this order.
In the present embodiment, it is necessary to always apply belt tension so that the round belt 75 does not slip at the drive pulley portion 86 of the motor pulley 85. If the round belt 75 is excessively tensioned, the rotational torque load of the drive motor increases, the power increases, and the belt life decreases. Conversely, if the round belt 75 becomes loose, it will not function as a conveying surface due to slip.
When the head is swung by the swing unit 77, the distance between the head side pulley unit 20 and the tail side pulley unit 45 changes. Therefore, in order to keep the tension of each round belt 75 substantially constant, it is necessary to adjust the distance change.

  Therefore, in this embodiment, the first return roller 123, the second return roller 127, the third return roller 129, and the fourth return roller 125 are moved by rotating the take-up unit 111.

Next, the operation of the sorting conveyor A according to the present embodiment will be described for the sorting conveyor device X provided with the sorting conveyor A.
In the sorting conveyor device X according to the present embodiment, for example, as shown in FIGS. 16 and 17, one carry-in conveyor 150 is disposed on the tail pulley unit 45 side, and three carry-out conveyors are disposed on the head pulley unit 20 side. 155, 157 and 159 are arranged. In addition, the carry-in conveyor 150 is provided with a conveyed product identification device 161 that detects the type of the conveyed product W.

  When the conveyed product identification device 161 detects the type of the conveyed product W, it outputs a detection signal to the control device 163, and the control device 163 outputs the conveyed product W to one of the three carry-out conveyors 155, 157, and 159 based on the detected signal. In order to distribute to either of these, a control signal is output to the slide mechanism 13, and the head pulley unit 20 is moved to a predetermined carry-out conveyor position. The conveyed product identification device 161 is configured to recognize sorting information in accordance with downstream processes (for example, distribution of boxing operations), such as a barcode reader and an IC tag reader.

First, for example, as shown in FIGS. 1 and 2, the sorting conveyor A drives the slide table 17 by driving the stepping motor 19 and rotating the ball screw 15 based on the output signal from the control device 163. The head pulley unit 20 is moved to the position of the carry-out conveyor 157 shown in FIG.
The drive motor of the motor pulley 85 of the swing unit 77 is connected to a power source of a distribution conveyor device (not shown) and is rotating. Along with the rotation of the motor pulley 85, the idler pulley 25 of the head side pulley unit 20, the first return roller 123, the second return roller 127, the third return roller 129 and the fourth return roller 125 of the take-up unit 111 and the tail side pulley unit. A round belt 75 wound around 45 idler pulleys 49 rotates in the direction of the arrow in FIG.

Next, for example, as shown in FIG. 16, when it is detected that the conveyed product W on the carry-in conveyor 150 is distributed to the carry-out conveyor 155 by the conveyed product identification device 161, the conveyed product identification device 161 transfers to the control device 163. On the other hand, a signal for distributing the conveyed product W to the carry-out conveyor 155 is output to the stepping motor 19 of the slide mechanism 13.
At the same time, the conveyed product W is separated on the carry-in conveyor 150 so that the next conveyed product W is not continuously sent to the sorting conveyor A.

The stepping motor 19 of the slide mechanism 13 is driven based on the output signal from the control device 163, rotates the ball screw 15 to move the slide table 17, and moves the head side pulley unit 20 to the position of the carry-out conveyor 155 shown in FIG. Move to.
In the head-side pulley unit 20, one end 21 a of nine pulley assemblies 21 is moved from the position of the carry-out conveyor 157 to the position of the carry-out conveyor 155 as the slide table 17 moves.

  Along with the movement of the head-side pulley unit 20, the bearing base 31 that supports the nine pulley assemblies 21 is also moved at the same time, and along with the movement of the slide table 17, the shaft 18 is attached to the lower base member 34 of the bearing base 31. The connecting plate 87 on the head side pulley unit 20 side of the swing unit 77 that is supported rotates around the swing unit rotation shaft 80 while sliding around the shaft 18. By rotation of the connecting plate 87, the central shaft 41 of the link plate interlocking shaft 41 inserted through the hole 43 of the link plate 39 is inserted into the hole 90a of the mountain-shaped rising portion 90 provided in the middle of the connecting plate 87, By linking the link plate 39 by the shaft 41, the movement of the link plate 39 is moved to each pulley assembly 21 by the link plate interlocking shaft 41 attached to the other end portion 21 b of the nine pulley assemblies 21. Accordingly, each pulley assembly 21 rotates in the shaft hole 32 a of the bearing base 31 around the rotation shaft 35 of each pulley assembly. Accordingly, the idler pulleys 25 that are pivotally supported by the pulley assemblies 21 are simultaneously rotated at equal intervals in the direction perpendicular to the conveying direction.

  At the same time, the connecting plate 87 is inserted into the hole 88 provided in the tip portion through the shaft 18 inserted into the bearing 16 of the slide table 17 and the hole 29 of the link plate 39 inserted into the hole 90a of the rising portion 90. The slide table 17 is moved along with the shaft 57. As the connecting plate 87 moves from the state of FIG. 2 to the state of FIG. 16, the slide rail 91 is guided by the rail base 93 and protrudes outward. In the state of FIG. 2, the connecting plate 87 has a total length of the guide rail so that the end of the connecting plate 87 is positioned substantially on the end side of the guide rail 93 in the length adjusting mechanism 89 as shown in FIG. 16, in the state of FIG. 16, in the length adjustment mechanism 89, as shown in FIG. 18, the end of the connecting plate 87 is positioned substantially in the middle of the guide rail 93 in the direction of the ink plate 39. Protruding to

Along with the movement of the connecting plate 87, the swing unit 77 is rotated around a bearing 72 provided on the other end portion 10b of the gantry 10 through a shaft 80 inserted through the hole 78a of the connecting plate 78. . At the same time, the swing unit 77 is rotatably connected to a shaft 57 that is pivotally supported by the link plate 55 of the tail side pulley unit 45 via two angle members 97 and 101.
The cam follower 109 is always applied in the direction in which the cam follower 109 comes into contact with the cam follower rail 105 due to the arrangement of each round belt 75 and the first return roller 123, the fourth return roller 125, the second return roller 127, and the third return roller 129. The cam follower 109 and the cam follower rail 105 cause the take-up unit 111 to rotate in the direction perpendicular to the conveyance direction (vertical direction) using the linear power of the slide mechanism 13.

  Therefore, when the swing unit 77 rotates, the take-up unit 111 causes the cam follower 109 to move from the top 105a of the cam follower rail 105 along the side 105b. Along with this movement, the take-up unit 111 has two fork-shaped take-up rotating plates 117 that are rotated with respect to the take-up unit mounting bracket 121 about the screw 120, and tilted as shown in FIG. From the state, the standing state shown in FIG. Therefore, the first return roller 123 rises away from the second return roller 127, the fourth return roller 125 rises to the third return roller 129 side, and the tension applied to the rotating round belt 75 is made constant. The length of the round belt 75 accompanying the rotation of the head swing unit 77 is appropriately adjusted.

Next, when the head side pulley unit 20 is moved to the position of the carry-out conveyor 155, the conveyed product W is transferred onto the sorting conveyor A via the round belt 75, and to the carry-out conveyor 155 as the round belt 75 rotates. Discharged.
Next, the conveyed product W discharged to the discharge conveyor 155 is transferred to a predetermined place by the discharge conveyor 155.
At the same time, when a passage detection sensor (not shown) provided at the entrance of the discharge conveyor 155 detects discharge of the conveyed product W from the sorting conveyor A, the detection signal is output to the control device 163, and the control device 163 carries in The separation work of the conveyed product W by the conveyor 150 is stopped, and the next conveyed product W can be transferred to the sorting conveyor A by the carry-in conveyor 150.

Then, when it is detected that the next conveyed product W is discharged to the carry-out conveyor 157 by the conveyed product identification device 161, the stepping motor 19 of the slide mechanism 13 is driven based on the command of the control device 163, and the head side The pulley unit 20 is moved to the position of the discharge conveyor 157.
The head-side pulley unit 20 is moved in the opposite direction to that described above, and is moved from the position of the carry-out conveyor 157 to the position of the carry-out conveyor 155.
As the head side pulley unit 20 moves, the swing unit 77 is also rotated while adjusting the length by the length adjusting mechanism 89.

At the same time, the take-up unit 111 also changes from the standing state shown in FIG. 17 to the inclined state shown in FIG.
Next, when the head-side pulley unit 20 is moved to the position of the carry-out conveyor 157, the conveyed product W is transferred onto the sorting conveyor A via the round belt 75, and to the carry-out conveyor 157 as the round belt 75 rotates. Discharged.
Next, the conveyed product W discharged to the discharge conveyor 157 is transferred to a predetermined place by the discharge conveyor 157.

At the same time, when a passage detection sensor (not shown) provided at the entrance of the discharge conveyor 157 detects the discharge of the conveyed product W from the sorting conveyor A, the detection signal is output to the control device 163, and the control device 163 carries in The separation work of the conveyed product W by the conveyor 150 is stopped, and the next conveyed product W can be transferred to the sorting conveyor A by the carry-in conveyor 150.
Then, when it is detected that the next conveyed product W is discharged to the carry-out conveyor 159 by the conveyed product identification device 161, the stepping motor 19 of the slide mechanism 13 is driven based on the command of the control device 163, and the head side The pulley unit 20 is moved to the position of the discharge conveyor 159.

The head side pulley unit 20 is moved from the position of the carry-out conveyor 157 to the position of the carry-out conveyor 155.
As the head side pulley unit 20 moves, the swing unit 77 is also rotated while adjusting the length by the length adjusting mechanism 89.
At the same time, the take-up unit 111 also changes from the inclined state shown in FIG. 2 to the standing state shown in FIG.

Next, when the head-side pulley unit 20 is moved to the position of the carry-out conveyor 159, the conveyed product W is transferred onto the sorting conveyor A via the round belt 75, and to the carry-out conveyor 159 as the round belt 75 rotates. Discharged.
Next, the conveyed product W discharged to the discharge conveyor 159 is transferred to a predetermined place by the discharge conveyor 159.
At the same time, when a passage detection sensor (not shown) provided at the entrance of the discharge conveyor 159 detects the discharge of the conveyed product W from the sorting conveyor A, the detection signal is output to the control device 163, and the control device 163 carries in The separation work of the conveyed product W by the conveyor 150 is stopped, and the next conveyed product W can be transferred to the sorting conveyor A by the carry-in conveyor 150.

As described above, the sorting conveyor A according to the present embodiment and the sorting conveyor device X including the sorting conveyor A are configured so that the transported object W transported by the loading conveyor 150 is predetermined according to the type thereof. , 159, the sorting conveyor A can be caused to perform a sorting operation under the control of the control device 163.
In the sorting conveyor A according to the present embodiment, the head side pulley unit 20 and the tail side pulley unit 45 are rotated with the nine pulley assemblies 21 and 47 as their respective axes 35 and 53 as rotation axes, and the rotation axes thereof. Is positioned on the outside of the gantry 10 with respect to the respective idler pulleys 25 and 49, and the link plates 39 and 55 are rotatably attached to the nine pulley assemblies 21 with the respective shafts 41 and 57 as the rotation shafts. The idler pulleys 25 and 49 rotated with the rotation of the nine pulley assemblies 21 and 47 rotate the shafts 35 and 53 at equal intervals in accordance with the movement of the slide table 17 of the slide mechanism 13. It is rotated as an axis.

Therefore, increasing the distribution angle of the distribution conveyor A does not affect the endless rotation of the round belt 75.
In addition, as shown in FIG. 19, the idler pulleys 25 and 49 do not protrude to the outside of the gantry 10 during rotation, so that the carry-in conveyor 150, the carry-out conveyors 155, 157, and 159 arranged adjacent to each other There is no buffering.
In other words, the centers 29x and 49x of the shaft rotation of the idler pulleys 25 and 49 are not the pulley centers 29y and 49y, but are positioned so that no gap is formed even if they are rotated.
On the other hand, if the centers 29x and 49x of the shaft rotation of the idler pulleys 25 and 49 are set to the pulley centers 29y and 49y, a gap is generated, which is not preferable.
Accordingly, the gap G between the sorting conveyor A and the carry-in conveyor 150 arranged on the upstream side of the sorting conveyor A, and the gap G between the sorting conveyor A and the carry-out conveyors 155, 157 and 159 arranged on the downstream side of the sorting conveyor A are set. It can be made smaller.

In the above-described embodiment, as the transported object identification device 161, for example, a device that recognizes simple sorting information such as a barcode reader and an IC tag reader has been described. However, the present invention is not limited to this, and for example, a metal detector, You may use the apparatus which recognizes foreign material mixing, a pass, and rejection, such as an X-ray inspection apparatus, a weight checker, an image processing (color and shape inspection) apparatus. In this case, there are many distributions in two directions.
Further, in front of the transported object identification device 161, it is necessary to separate the transported object W (make an interval) so that the transported object W does not adhere and flow. The separation is performed by using a difference in conveyor speed or by temporarily staying, and separating them one by one using a stopper or the like.

Moreover, in the said embodiment, although the distribution conveyor A and the distribution conveyor apparatus X provided with this distribution conveyor A demonstrated distribution, this invention is not restricted to this, You may use it for merge.
For example, the description will be made on the assumption that the transport objects W flowing from three conveyors (in the present embodiment, carry-out conveyors 155, 157, and 159) are aggregated into one conveyor (in this embodiment, the carry-out conveyor 150). Then, the merge does not need to identify information, and what flows from the three conveyors (in the present embodiment, the carry-out conveyors 155, 157, and 159) is transferred to the sorting conveyor A in the order of arrival in principle. However, if there is a traffic jam, stop at the front end of each conveyor, measure the timing, and put it into the confluence conveyor.

  In the above embodiment, the case where the slide table 13 is moved by the stepping motor 19 via the ball screw 15 has been described in the above embodiment, but the present invention is not limited to this. For example, the slide mechanism 13 is slid by a timing belt instead of the ball screw. It is good also as a structure which moves a table. Further, the head side pulley unit 20 may be moved using a pneumatic or hydraulic cylinder.
