Description

  The present invention relates to an attachment for preventing slipping of large bags, and in particular, it is effective that baggage stays on the belt conveyor when transporting large bags such as suitcases for travel on a belt conveyor system at an airport terminal. The present invention relates to an attachment for preventing slippage of a large bag.

  At large airport terminals, a belt conveyor system (Baggage Handling System) (hereinafter referred to as Baggage Handling System) is used to sort passenger airplanes checked at the counter into planes on board, and to carry them to the loading container. Simply abbreviated as BHS).

  For example, at Narita International Airport, each terminal is equipped with a BHS. For example, the total length of the BHS including the first and second terminals is approximately 22.5 km, and the total length of the belt conveyor is 22.5 km. Since it is stretched across layers, the difference in height of BHS is also large.

  In addition, the operation of the BHS constantly monitors the movement of the belt conveyor in each central monitoring room so that delivery can be reliably performed according to the flight schedule of the aircraft.

  In this way, a large-scale BHS has a structure in which a large number of belt conveyors are connected, and there are curves and gradients in the route of the system, so that it can be joined to an annular loop line to transport baggage to the intended transport location. However, when moving between the lines, there is a place where the conveyor speed of the belt conveyor is temporarily adjusted to accelerate at a high speed and transfer the baggage.

  A slight gap is provided between adjacent belt conveyors constituting the BHS.

  On the other hand, when a baggage is transported by a BHS belt conveyor, the baggage may flow and stay due to various factors. There are various types of baggage, but many large bags such as suitcases for travel are transported among them. Some of these large ridges are equipped with double-wheel casters on the front, back, left and right of the bottom surface of the main body in order to facilitate moving and transporting and alleviating shocks such as vibration. These casters are rotatable 360 degrees in a plane perpendicular to the caster mounting shaft mounted on the bottom surface of the bag main body.

  FIG. 5 shows the configuration of a double wheel caster 40 to be mounted on a suitcase which is a large bag as described above. 5A is a perspective view of the caster 40, FIG. 5B is a side view, and FIG. 5C is a cross-sectional view taken along the line dd in FIG. 5B.

  The caster 40 includes a wheel 41 of a double wheel and a caster main body 43 that receives the caster mounting shaft 42 and rotatably supports the wheel 41 of the double wheel.

  FIG. 6 shows a schematic perspective view of the caster body 43. As shown in FIGS. 5 (C) and 6, the caster body 43 is provided on the front side, and is disposed between a bottomed cylindrical mounting portion 44 that receives the caster mounting shaft 42 and both wheels 41. The wheel support part 45 that rotatably supports the wheel 41, the axle 46, the attachment part 44, and the wheel support part 45 are integrally connected to each other, and are provided in a portion extending from the attachment part 44 to the rear part of the caster. 41 and a connecting portion 47 having a shape following the curve of the outer peripheral surface 41A.

  The caster mounting shafts 42 of the suitcase body are firmly attached to the front, rear, left and right of the bottom of the large bag body (not shown) with the axial direction facing downward. Further, a shaft mounting hole 44A for receiving the caster mounting shaft 42 is provided inside the mounting portion 44 of the caster main body 43 mounted on the caster mounting shaft 42. By inserting the caster mounting shaft 42 into the shaft mounting hole 44A, the caster is mounted. 40 is attached to the caster mounting shaft 42 so as to be rotatable in a plane perpendicular to the shaft.

  Further, the caster main body 43 is provided with a through hole through which the axle 46 is inserted, and serves as a bearing portion 48. A pair of wheels 41 are attached to both sides of the axle 46 and are rotatable with respect to the wheel support portion 45.

  For example, as shown in FIGS. 7A and 7B (1), the suitcase 51 having the above-described structure is placed sideways with respect to the surface of the belt conveyor 49 of the BHS. At the stage, the caster 40 on the lower side of the suitcase (belt conveyor side) is turned sideways as shown in FIG. 7B (1) and FIG. 8A, and the lower wheel 41 of the suitcase does not rotate. It is in a state. However, as shown in FIGS. 7A and 7B (2), at the stage where the lower wheel 41 is conveyed at the joint between the belt conveyor 49 and the belt conveyor 49, the joint of the belt conveyor 49. The lower caster 40 may rotate about the caster mounting shaft 42 in the gap portion existing in FIG. 8, and a part of the caster may enter the gap portion as shown in FIG.

  Thus, when the caster 40 of the suitcase 51 enters the gap of the seam, the wheels 41 of the caster 40 may rotate with the movement of the belt conveyor 49, and it may be difficult to escape from the gap of the seam. Even if it can be pulled out, as shown in (3) of FIG. 7B, the suitcase 51 is supported only by the caster 40 that rotates when it is in contact with the placement surface of the belt conveyor 49 (α). In this state, when the vehicle reaches the inclined belt conveyor 49 or the like, the wheel 41 may rotate (FIG. 8C), and a phenomenon may occur in which the inclination slides downward due to the weight of the suitcase 51. Further, when the suitcase 51 joins the loop line and accelerates at a high speed from the stop state, the suitcase 51 may not join the unintended place or move to the loop line due to the rotation of the wheels 41.

  When the above-described phenomenon occurs in the connecting portion or the inclined portion of the belt conveyor 49, the suitcase 51 may stay in the place or become difficult to travel, and may block the route of the subsequent baggage.

  In such a situation, the person in charge of monitoring the movement of the belt conveyor 49 in the central monitoring room stops the BHS, rushes to the staying site, and the suit where the problem has occurred It is necessary to remove the caster 40 of the case 51 from the gap, or to collect the suitcase 51 and place it on the BHS again to carry it again. For this reason, it is very time-consuming, and the baggage may be damaged due to the retention of the baggage, which may lead to a delay in the flight.

  The present invention has been made in view of the circumstances as described above. When carrying a large bag such as a suitcase equipped with double wheel casters on the front, rear, left and right of the bottom of the bag body at the airport terminal BHS. Even if a caster gets into the gap of the belt conveyor connection, the caster can be easily escaped, preventing the baggage from staying and effectively preventing the damage of the baggage and the delay of the flight It is an object to provide an attachment for preventing slipping of a large ridge that can be used.
