【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0013] FIG. 1 shows a chain conveyor 10 equipped with a conveyance sorting device according to the present invention. Some are shown. This chain conveyor 10 includes a plurality of chains (three in the illustrated embodiment). This is made up of two endless annular conveyor chains 11 arranged in parallel, each conveyor chain 11 Although not shown in the figure, the There is. A drive motor is connected to one sprocket, and the drive motor The force causes the conveyor chain 11 to move in a circular manner. Therefore, the conveyed object P is supported on the upper surface of the conveyor chain 11 and conveyed.

[0014] At the sorting position, pop-ups are installed on both the left and right sides of each conveyor chain 11. A rail 12 is arranged. In the following explanation, transport chains may be used as necessary. A subscript a is attached to the member on the right side of the conveyance direction of the belt 11, and a subscript a is attached to the member on the left side in the conveyance direction. It will be explained with the letter b added. The pop-up rail 12 moves from the conveyor chain 11 to a predetermined position. They are arranged at intervals and extend parallel to the conveyor chain 11. these pops Although not shown, the up rail 12 is raised by a suitable driving means such as a pneumatic cylinder. It is designed to be moved downward.

[0015] In addition, as shown in FIGS. 2 to 5, there are many friction wheels 13 are attached to each other at regular intervals. Illustrated illustration In the embodiment, the friction wheel 13 is connected to the conveyor chain via the swing arm 14. It is attached to the end of the pin 15 that constitutes the lane 11. The swing arm 14 The pin 15 to be connected is longer than the other pins and protrudes from the left and right sides. A swing arm 14 is supported on the protruding portion of the swing arm 14 . Is there a swing arm 14 on the pin 15? In order to support this load, the conveyance through which the pin 15 passes is Boss portions are formed on the link plates 16 and 17 of the chain 11. on the other hand, A wheel support pin 18 is fixed to the free end of the swing arm 14. The friction wheel 13 is attached to the pop-up rail 12 by the rail support pin 18. is rotatably supported in a vertically upward position. Therefore, the pop-up rail 12 When raised, the friction wheel 13 is pushed by the pop-up rail 12. As the transport chain 11 moves in circulation, the pop-up rail It is designed to roll on 12. Although it is not clearly shown in the diagram, the swing arm In order to limit the swinging of conveyor chain 11 within a certain angular range, a stopper It is provided on the link plate 16 of.

[0016] The tip of the wheel support pin 18 is bent at a certain angle in the opposite direction to the conveyance direction. A sorting wheel 19 is rotatably attached thereto. In the illustrated embodiment, the right sorting wheel 19a of each conveyor chain 11 is The rotating surface of the left sorting wheel 19b is oriented diagonally to the right. It is pointed in the direction you want. The inner surface of this sorting wheel 19 has friction holes. It is frictionally engaged with the conical surface formed on the outer surface of the eel 13, and the friction wheel When the wheel 13 rotates, the sorting wheel 19 also rotates. ing.

[0017] When not sorting, as shown in FIGS. 3 and 4, the pop-up rail 12 is located below the friction wheel 13. At this time, the swing arm 14 is lowered by its own weight. The friction wheel 13 and the sorting wheel 19 are connected to a conveyor chain. It is arranged at a position below the upper surface of the tube 11. On the other hand, when sorting, a pop-up When the wheel 12 is raised, the associated friction wheel 13 is raised, as shown in FIG. is in contact with the pop-up rail 12, and its swing arm 14 is in contact with the upper stopper (not shown). ), and the sorting wheel 19 is pushed up until it touches the conveyor chain 11 protrudes above the top surface of

[0018] In such a configuration, the operation of the transported object sorting device according to the present invention will be explained below. explain.

[0019] First, when not sorting, the pop-up rail 12 is controlled by the drive means. It is located in the lower position. At this time, as mentioned above, friction wheel 1 3 and the sorting wheel 19 are located below the upper surface of the conveyor chain 11, and The conveyed object P placed on the upper surface of the chain 11 moves straight as it is.

[0020] Next, during conveyance, the conveyed object P on the conveyance chain 11 is moved to the right side takeaway. When sorting onto the conveyor Ta, the conveyed items P must be completely in the sorting position. , raise the pop-up rail 12a on the right side of each conveyor chain 11. So As a result, the friction wheel 13a on the right side of the conveyor chain 11 pops up. While being pushed up by the rail 12a, the sorting wheel 19a The support member 11 protrudes upwardly from the conveyor belt 11 and supports the lower surface of the conveyed object P. pop up rail The friction wheel 13a pushed up by the conveyor chain 11 At the same time, it moves in the conveying direction, and at the same time rolls on the pop-up rail 12a. A rotational movement (in the direction of arrow C in FIG. 5) is generated. The rotation of this friction wheel 13a The sorting wheel 1 is frictionally engaged with the friction wheel 13a by rotation. 9a also rotates in the direction of arrow D. Therefore, when placed on the sorting wheel 19a, The transported object P is moved diagonally to the right in parallel by the rotation of the sorting wheel 19a. Then, it is transferred to the takeaway conveyor Ta.

[0021] The conveyance chain 11 does not move, and the sorting wheel 19a performs only rotational movement. Assuming that, as schematically shown in FIG. It moves in the inclination direction (angle θ direction) of 9a and reaches the position indicated by the dashed line. However, the actual At this time, the sorting wheel 19a is moving together with the conveyor chain 11, so the The article P will move from the solid line position to the dotted line position. Dotted line from the rear end of the solid line position The distance L to the front end of the position is the length of the sorting position, that is, the length of the pop-up rail 12. It is also important in determining the length, and can be determined as follows.

First, if the distance of lateral movement of the conveyed object P is W, the moving speed of the conveyance chain 11 is v, the diameter of the friction wheel 13 is d ₁ , and the diameter of the sorting wheel 19 is d ₂ , then in lateral movement The time t required is

[Math 1] becomes.

[0023] Therefore, the distance L ₁ that the conveyor chain 11 moves during this time t is:

[Math 2] becomes.

[0024] Therefore, the distance L is calculated _as

[Math 3] becomes.

[0025] When sorting the conveyed items P to the takeaway conveyor Tb on the left, each conveyance channel If you raise the pop-up rail 12b on the left side of the lane 11, you can sort to the right side. Similarly, the left-facing sorting wheel 19b protrudes and the conveyed items P are moved to the left. be moved.

[0026] When sorting is performed using the above procedure, the conveyed items P are separated by rotation of the sorting wheel 19. Because it is moved, it moves in parallel and accumulates in the width direction on the takeaway conveyor T. will be done. In addition, the sorting wheel 19 is always used together with the conveyor chain 11. Since it is moving straight, the conveyed items P are transferred from the conveying chain 11 to the sorting wheel 19. Even if the transport chain 11 moves in a straight line, it will not be decelerated and will move without going against the inertia force caused by the linear movement of the conveyor chain 11. Sorted into Mouse.

[0027] In the above embodiment, the sorting wheel 19 is frictionally engaged with the friction wheel 13. The structure is such that the rotational force is transmitted by the Various methods can be considered, such as using gears and belts, and the rotation speed and method The direction can also be changed as appropriate.

[0028] In addition, the friction wheel 13 is attached to the conveyor chain 11 so that it can move up and down. However, the means is not limited to the swing arm 14, but other means may be used. good. For example, a guide rail extending vertically downward may be installed on the link plate of the conveyor chain 11. The friction wheel 13 can be moved up and down using this guide rail. It is also possible to adopt a configuration like this.

[0029] Furthermore, although the above embodiment has a configuration that allows sorting in both left and right directions, When sorting only in one direction, the pop-up rail should be placed on the side of the sorting direction. The pop-up rail on the other side will be omitted. Tee throughout the conveyor line – If the quaway conveyor is on one side, the friction wheels and As for the sorting wheel, it is only necessary to install it on the side in the sorting direction. .

[0030]

[Effect of the idea]

As can be understood from the above, according to the present invention, the conveyed object can be moved from the longitudinal direction to the width direction. Since it can be changed and sorted, the number of storage units per unit length can be increased. This allows for effective use of space.

[0031] Also, it is not affected by the inertial force caused by the linear movement of the chain conveyor during sorting. Therefore, conveyed items can be finished smoothly without reducing the speed of the chain conveyor excessively. It is possible to improve the sorting efficiency. Also, for conveyed items This also has the effect of preventing shock from being applied.

[0032] Furthermore, the sorting device according to the present invention uses the movement of a chain conveyor to perform sorting. The pop-up rail is rotated, and the drive source is only used to move the pop-up rail up and down. Therefore, the configuration is extremely simple and maintenance is easy. Also, sorting Since the pop-up rail only needs to be moved up and down when It becomes very small.
