BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a logistics trolley, and more particularly, to a two-way switching mechanism of a logistics trolley for conveniently and rapidly transferring a large amount of articles on a complicated route of a ceiling.

Usually, a large number of logistics transfer devices having trolleys and hangers are installed on the path set for the purpose of transferring a relatively light semi-finished product or finished product at an industrial site. Especially in the field of apparel, a ceiling hanger type logistics transfer device is preferred for mass transfer at the manufacturing site and the shipping scene.

Reference may be made to Korean Utility Model Publication No. 1998-0008079 (Prior Art 1) and Korean Patent Registration No. 0520061 (Prior Art Document 2) as prior art documents related to devices for transferring various kinds of logistics.

The prior art document 1 discloses a device for suspending clothes on a trolley and suspending the tilting table to the ceiling and installing a circulating chain conveyor on the trolley with a chain in which a driving roller and a side roller are alternately arranged And a gear is meshed on the one chain to condense the motor to the motor, and to transfer the trolley to be moved to the push rod. Accordingly, it is expected that the management will be automated to reduce the labor force, increase the productivity, and reduce the cost.

Prior Art 2 includes a guide rail having a main orbit provided with a pair of rail members and a branch orbit branched from the main orbit; At least one pair of wheels mounted on the conveying body and one roller provided on the conveying body so that the conveying body can descend so as to run on the branching track or run on the main track; And a controller for controlling the lifting and lowering of the roller. Accordingly, the structure is simple, preventing failure and expecting the effect that the wheel travels the guide rail more safely.

However, according to the prior art document 1, it is difficult to form a complicated path having many intersections such as interchanges, branches, joins, etc. in the ceiling for transporting a relatively small size article. According to the prior art document 2, It is difficult to increase the conveying speed in a complicated path. Therefore, the above-mentioned prior art has a limitation in applying to the application of carrying and storing a large amount of clothing densely housed in a hanger.

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

The present invention proposes a mechanism for switching the travel path of the trolley 20 on a rail 10 having a plurality of intersection points 15. But is not limited to, a logistics system that moves a large amount of garments to a trolley 20 within an established building structure. In FIG. 1, the structure may be composed of a plurality of layers, and the rail 10 is provided in a complicated area including the stairs 12 and the warehouse racks 13. The rail 10 constitutes a movement path of the trolley 20 by connecting a circular cross-section pipe member (pipe) with a straight line or a curved line to the ceiling of the structure. The trolley 20 has a configuration in which a hanger 24 for receiving articles (clothes) is connected to the lower side of a pulley 26 running on the rail 10 via an arm 22.

At this time, as the density of the rail 10 increases in the distribution system, a plurality of intersection points 15 necessarily occur. The intersection point 15 is required to switch the path of the trolley 20 approaching from one direction and the path of the trolley 20 approaching from the other direction. Of course, performing these functions manually results in a reduction in efficiency of the logistics system. Therefore, the present invention is capable of automatically switching the path at the intersection point 15, and does not use a separate power source, thereby improving operational reliability.

On the other hand, the intersection point 15 of the present invention will be described by setting three rails 10 to meet and join in one direction.

According to the present invention, the frame 30 is provided with two connecting rails 35 on the upstream side and one connecting rail 35 on the downstream side so as to constitute the intersection 15.

The frame 30 may be substantially triangular in shape, similar to the shape of the intersection 15. Three connecting rails 35 are arranged on one surface of the frame 30 in a triangular shape with respective brackets 37 interposed therebetween. The two upstream connecting rails 35 and one downstream connecting rail 35 are spaced at the same distance and the outer end of each connecting rail 35 is connected to the rail 10 which has reached the intersection 15 . The connecting rail 35 also uses a tube member having the same dimensions as the rails 10 described above. The bracket 37 supporting the connecting rail 35 is installed in a direction that does not cause interference when the trolley 20 is moved in one direction or the other direction.

Refers to the direction toward the center of the frame 30 and the terms "outer end" and "outer side" refer to the direction away from the center of the frame 30. In the description of the present invention, "inner end" &Quot; Upstream "refers to the upper side and" Downstream "refers to the lower side.

According to the present invention, the switching means 40 is rotatably mounted on the frame 30 via the switching lever 41 and the pivotal table 42 so as to support the switching rail 45 in the spacing space of the connecting rail 35 It is a structure that is installed as much as possible. The switching means 40 is connected to the upstream side connecting rail 35 and the downstream connecting rail 35 or the upstream side other connecting rail 35 and the downstream side connecting rail 35 by using the switching rail 45 provided on the pivot table 42, The connection between the connecting rails 35 is interrupted. The turning force of the pivoting table 42 is transmitted to the switching lever 41 to cause the pivoting movement of the switching rail 45 disposed in the spacing space as described later. The switching rail 45 also uses a tubular member of the same size as the connecting rail 35 and the rail 10 described above. The connection rail 35 on the upstream side and the connection rail 35 on the downstream side are spaced by the same distance so that the conversion rail 45 smoothly rotates without interference and connects the path with the same height as the connection rail 35.

According to the detailed configuration of the present invention, the switching lever 41 of the switching means 40 is formed in a semicircular shape so as to be rotatable on the support 31 of the frame 30, And is rotated by the contact force by the approaching trolley (20). The support 31 is fixed to the intermediate position of the connecting rail 35 opposed to the frame 30 on the upstream side. The switching lever 41 rotatably installed at the upper end of the support 31 is formed into a semicircular arc with a constant curvature so that the trolley 20 can be smoothly contacted. When the arm 22 of the trolley 20 makes sliding contact with the circumference of the switching lever 41, the switching lever 41 rotates to rotate the pivoting table 42 and the switching rail 45.

2, when the switching lever 41 is deflected by the connecting rail 35 on the right side, the switching lever 41 is contact-rotated by the arm 22 of the trolley 20 which is moving to the right, If it is deflected by the left connecting rail 35, it is contact-rotated by the arm 22 of the trolley 20 entering to the left.

According to the detailed configuration of the present invention, the switching rail 45 of the switching means 40 is connected to the connecting rail 35 on the downstream side so as to be rotatable via the hinge shaft 48. It is preferable that the position of the hinge shaft 48 for rotating the switching rail 45 is set to be the same as that of the hinge shaft (not shown) of the rotating table 42. [ In this way, since the connection between the lower end of the conversion rail 45 and the downstream connection rail 35 is surely ensured, it is advantageous to connect the upper end of the conversion rail 45 to the upstream connection rail 35.

In this case, the switching rail 45 of the switching means 40 is coupled with the pivoting table 42 through the opening 33 of the frame 30. The switching rail 45 located on the bottom surface of the frame 30 is coupled to the pivot table 42 located on the upper surface of the frame 30 by using the bracket 37. [ The opening 33 of the frame 30 is formed in such a range as to assure the left and right pivotal movement of the switching rail 45 and the bracket 37. This is advantageous in terms of the simplicity of the structure in which the pivot table 42 and the switching rail 45 are combined.

According to the present invention, since the operating means 50 transmits the turning movement of the switching lever 41 by the contact of the trolley 20 to the turning table 42 to change the path direction of the switching rail 45 to be. The operating means 50 operates the switching lever 41 with the moving force of the trolley 20 without using any separate power source or power so that the turning position of the turning table 42 and the switching rail 45 mounted thereon is switched to the left and right To the administrative unit.

The operating means 50 includes a driving gear 51 connected to the shaft of the switching lever 41, a driven gear 52 engaged with the driving gear 51, A rod 54 connected to the shaft and a slider 56 connected to an end of the rod 54 to slide the slit 43 of the rotary table 42 and a spring 58 for applying an elastic force to the slider 56 .

In Fig. 4, the pair of gears 51 and 52 are mounted on the support 31 of the frame 30 in an engaged state. The drive gear 51 is coupled concentrically with the switching lever 41 at one point of the support 31 and the driven gear 52 is coupled concentrically with one end of the rod 54 at another point of the support 31 . The gears 51 and 52 are helical gears, but a spur gear or the like may be used. The rod 54 is engaged with the driven gear 52 at one end and the slider 56 at the other end. The slider 56 is accommodated so as to be slidable on the slit 43 of the pivotal table 42. A tension spring (58) is provided between the slider (56) and the end of the pivot stage (42).

On the other hand, the switching lever 41 may be rotated by a contact force caused by the movement of the trolley 20, or may be provided with a handle (not shown) on the axis of the switching lever 41 so as to switch the path manually in an emergency.

Assuming that the operator pushes the trolley 20 by the one side connecting rail 35 on the upstream side and pushes the trolley 20 by the other side connecting rail 35 on the upstream side in the operation, The conversion rail 45 is automatically switched and this operation is understood more clearly through Figs. 4 to 6. Fig. The switching lever 41 located at the left stroke end in Fig. 4 is rotated in the clockwise direction by the contact of the trolley 20 and the rotation of the switching lever 41 is transmitted to the rod 54 via the gears 51 and 52 Causing the counterclockwise rotation, and the spring 58 is pulled as the slider 56 moves to the inside of the slit 43. 5, when the rotary table 42 rotates to the left by the rotation of the rod 54, the rod 54 and the rotary table 42 are positioned on a straight line at the position of the support 31, 58 are pulled to the maximum tension. When the switching lever 41 reaches the right stroke end as shown in Fig. 6, the pivot rod 42 reaches the left stroke end, the spring 58 returns to the initial state, and the path of the switching rail 45 The conversion is completed. The spring 58 exerts an elastic force so that the path of the switching rail 45 is maintained at the stroke end of either one of Fig. 2 or Fig.

At this time, the trolley 20 always moves from the upstream side to the downstream side, and does not allow reverse movement.

As described above, according to the present invention, the path of the trolley 20 joining at one side or the other side of the rail 10 at the intersection 15 is instantly switched, thereby improving the convenience of the logistics work and improving the productivity.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
