DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baggage transfer system for, for example, a baggage handling system provided at an airport or the like for transferring baggage checked in at a boarding counter or the like to a predetermined boarding machine (spot). The present invention relates to a belt conveyor device.

[0002]

2. Description of the Related Art In the past, spots were centralized in one terminal building, and sorting and transport of passengers and passenger baggage were performed in that building. In recent years, the international airport scheduled to open ports has become larger and larger. Accordingly, in order to increase the number of parked vehicles (spots), a layout in which a branch point called a satellite is provided at a location away from the terminal building is being adopted. In an airport having such a layout, the distance between the terminal building and the satellite is usually 500 m to 600 m near, and 1000 m to 200 m far.
There is a considerable distance of 0 m.

[0003] In this type of belt conveyor device, a sliding bed (for example, a flat iron plate) is provided on the lower surface of the conveyor belt, and the conveyor belt on which baggage is placed is horizontally supported by the sliding bed from below. The structure for carrying is common. this is,
Passenger baggage comes in a variety of properties, shapes and weights, including hard cases and soft bags, so it does not roll or jump on the traveling conveyor belt and is stable without damaging the baggage This is for transporting in a state. In other words, if you place a sliding bed under the conveyor belt and support it on a flat surface from below, the baggage on the conveyor belt will be transported in almost the same state as if it was placed on a stationary flat surface even when running. This is because that.

As a prior art document relating to a baggage transfer system at an airport or the like, there is Japanese Patent Application Laid-Open No. 6-71229. Also, it is not used for carrying baggage, but a belt conveyor device for continuously transporting powdery materials such as coal and cement while floating a conveyor belt sliding on a curved sliding bed with air. Fairness 7-64
405 and JP-A-7-206122.

[0005]

However, the above-mentioned conventional belt conveyor for carrying baggage has the following disadvantages.

When the length of the belt conveyor device is increased, frictional resistance due to the sliding action between the conveyor belt and the sliding bed increases, and the driving force must be increased. On the other hand, when the machine length is shortened, it is necessary to connect a large number of belt conveyor devices, so that the equipment cost becomes enormous and maintenance is troublesome.

Since the carry distance of baggage is greatly increased, it is necessary to increase the traveling speed of the conveyor belt in order to reduce the carry time. However, when the traveling speed is increased, abrasion of the conveyor belt is accelerated due to sliding friction with the sliding bed, and frictional heat is generated, so that the life of the conveyor belt is significantly reduced.

[0008] Since it is necessary to intermittently load relatively heavy baggage on the conveyor belt and to convey it at a high speed, as described in the above-mentioned publication, a pressure sufficient to lift the conveyor belt on the sliding bed. Blowing the air is difficult in terms of equipment and running cost is high, and the baggage to be conveyed may become unstable and fall.

The present invention has been made in view of the above points, and can carry baggage at a high speed in a stable state, without shortening the life of the conveyor belt, and greatly increasing the driving force even when the machine length is increased. An object of the present invention is to provide a belt conveyor device for carrying baggage which is unnecessary.

[0010]

In order to achieve the above object, a belt conveyor device for carrying baggage according to the present invention comprises a sliding bed having a flat upper surface along a carrying direction of baggage, and the sliding bed is provided on the sliding bed. In the belt conveyor device for carrying baggage, in which the upper revolving portion of the conveyor belt is disposed, a carrier roller is provided in the concave groove formed at an interval in the conveying direction in the middle of the sliding bed under the upper revolving portion of the conveyor belt. In addition, such as a hard case as the baggage (particularly having rigidity)
The top of the carrier roller protrudes 1.0 mm to 1.5 mm above the upper surface of the sliding bed so that the bag may not fall over when the bag is transported. , The distance between the carrier rollers,
At least when the baggage is not conveyed, the pressurized air is blown out from the air blowing holes described below, and the conveyor belt is set in a range of 500 mm to 1500 mm so as not to contact the upper surface of the sliding bed, and the width of the sliding bed is set. A large number of air blowing holes are formed in the central portion in the direction, and pressurized air is blown out from the air blowing holes to reduce sliding friction with the conveyor belt.

According to the baggage conveyor belt conveyor device of the present invention having the above-mentioned structure, a predetermined interval (preferably 500 mm to 1500 m) is provided in the middle of the sliding bed.
Since the carrier roller is disposed in m), heavy baggage can be transported with a smaller transporting force (driving force) as compared with a case where the belt supporting surface is constituted only by the sliding bed. In addition, the conveyor belt on the sliding bed does not float completely, but only blows out compressed air that reduces sliding friction resistance. There is no need to increase. Further, since the conveyor belt running on the sliding bed is slightly lifted by the introduction of the pressurized air, there is almost no step between the conveyor belt and the top surface of the carrier roller, so that the baggage can be stably conveyed. Furthermore, the frictional resistance between the conveyor belt and the sliding bed is reduced by the introduction of the pressurized air, and at the same time, the carrier roller disposed in the middle of the movement of the conveyor belt rotates to move the conveyor belt (and carry baggage). ), So the driving force for running the conveyor belt does not need to be increased much.
In other words, the traveling speed of the conveyor belt can be greatly increased.

[0012] According to a second aspect of the present invention, a continuous pressurized air supply duct is provided below the sliding bed, and the other end of an air supply pipe having one end connected to a common pressurized air source. Preferably, the duct is connected to a plurality of supply ports provided at intervals in the length direction of the duct, and pressurized air is simultaneously introduced into the duct.

According to the belt conveyor device of the present invention, the pressurized air is supplied from one pressurized air source (a pressurized air source generated by a blower or the like) substantially uniformly into a continuous duct below the sliding bed. Can be introduced,
Pressurized air is blown out from the many air blowing holes of the sliding bed almost evenly to the entire lower surface of the conveyor belt, and the sliding friction between the upper running part of the conveyor belt and the sliding bed is reduced almost uniformly over the entire length. I can make it.

According to a third aspect of the present invention, it is preferable that the conveyor belt is a flexible resin belt, and a cover member is attached so as to wrap both side edges of the conveyor belt from both sides of the sliding bed. .

According to the belt conveyor device of the present invention, since the belt is made of resin, it can be easily wiped even if dirt or the like adheres thereto. Driving force can be reduced. Furthermore, since both side edges of the conveyor belt are wrapped with cover members, the pressurized air blown out from the air blowing holes of the sliding bed is hard to escape to the outside, effectively reducing the sliding friction of the conveyor belt with a minimum amount of air. Can be reduced.

FIG. 5 is an enlarged perspective view of a part of the tension mechanism of the conveyor belt, and FIG. 6 is a state in which the conveyor belt of FIG. 1 is removed. It is the top view which expanded a part shown.

As shown in FIGS. 1 and 2, the belt conveyor device 1 of this embodiment has a long machine length of several hundred meters, and a plurality of belt conveyor devices 1 having a length before and after this are connected in series. They are connected and have a total length of 1000 m to 2000 m. Each belt conveyor device 1 includes a sliding bed 2 having a flat top surface from one end to the other end of the belt conveyor device 1. The sliding bed 2 is usually formed from an iron plate, and has a large number of air blowing holes 2.
a is penetrated vertically. Air outlet 2
a is disposed at the center in the width direction of the sliding bed 2 as shown in FIG. 6, which makes it difficult for the blown air to escape outward from both sides of the conveyor belt 13, which will be described later, and the floating of the conveyor belt 13. To work effectively. Although the diameter of the air blowing hole 2a is not limited, it is usually about 3 mm. Carrier rollers 3 are arranged on each sliding bed 2 at predetermined intervals (usually 500 mm to 1500 mm, in this example, 500 mm) in the transport direction (longitudinal direction). As described above, the installation height is set so that the top surface protrudes slightly above the upper surface of the sliding bed 2 into the concave groove 2b formed in the sliding bed 2, and in this example, the step height is 1.0 mm to 1.
After being adjusted to a range of 5 mm, it is rotatably supported via a bearing 3a.

Below the sliding bed 2, a box-shaped duct 4 having an open upper end is integrally mounted. As shown in FIG. 2, pressurized air inlets 4a are opened at predetermined intervals in the longitudinal direction of one side of the duct 4, and one end of the air supply pipe 5 is connected to each inlet 4a as shown in FIG. Are connected via a flexible joint 5a, and the air supply pipe 5 is provided with an opening / closing valve 5b. The other end of each air supply pipe 5 is connected to a common air supply pipe (main pipe) 6. The air supply pipe 6 has one end closed and the other end blower 7.
And pressurizes the air sucked from the suction port of the blower 7 and sends it into the duct 4 through the air supply pipe 6 and the air supply pipe 5.

As shown in FIG. 4, the belt conveyor device 1
A tail pulley 8 and a guide pulley 8a are rotatably disposed at one end (right end) in the longitudinal direction, and a head pulley 9 and a guide pulley 9a are rotatably disposed at the other end (left end). A drive pulley 10 driven by a drive motor 11 is provided below the duct 4 at a substantially intermediate position in the longitudinal direction, and a tension pulley 12 is rotatably and movably opposed to the drive pulley 10. Have been. An endless (annular) conveyor belt 13 is arranged so as to surround these pulleys 8 to 12 (except 11) and the carrier roller 3, and a plurality of conveyor belts 13 are provided on the lower surface side of the lower revolving portion of the conveyor belt 13. The return pulleys 14 are rotatably arranged at intervals. In addition, a return pulley 14 ′ for deflection is disposed above the drive pulley 10 and the tension pulley 12. The conveyor belt 13 is made of a synthetic resin, and is a lightweight belt reinforced by attaching a canvas to the back surface.

As shown in FIG. 5, both ends of a central shaft 12a which rotates integrally with the tension pulley 12 are rotatably supported by bearings 12b, and the bearings 12b are arranged in parallel at an interval vertically. It is slidably mounted along a pair of guide bars 12c. A support bar 15 is attached across the bearings 12b on both sides.
One end of the tow line 16 is fixed to the two retaining rings 15a of No. 5, and the other end side of the tow line 16 is integrated into one from the middle. The other end of the towing line 16 passes through a horizontal guide pulley 17 and a vertical guide pulley 18 rotatably supported below the duct 4, and then passes through a deflection pulley 20 at the upper end of the column 19. It is fixed to a counterweight 21 whose weight can be adjusted. As a result, a predetermined tension acts on the conveyor belt 13, and the rotation of the drive pulley 10 causes the conveyor belt 13 to rotate (rotate) in the counterclockwise direction in FIG.

As described above, the baggage transport belt conveyor device 1 according to the present embodiment is configured. Next, a description will be given of a baggage transport mode using the device 1 according to the present embodiment.

As the drive pulley 10 rotates, the conveyor belt 13 runs counterclockwise. In this state,
By driving the blower 7 to introduce the pressurized air into the duct 4, the air blowing holes 2 of the sliding bed 2 are formed.
Pressurized air blows out from a, and the conveyor belt 13 slightly rises from above the sliding bed 2. Therefore, the frictional force between the conveyor belt 13 and the sliding bed 2 is greatly reduced.

Various pieces of baggage A such as a hard case and a soft bag are placed on the conveyor belt 13 and conveyed, but the conveyor belt 13 running on the sliding bed 2 is in a position where the baggage A is not placed. Since it rises slightly due to the introduction of pressurized air, it runs with little frictional resistance. Further, at the position where the baggage A is placed, the conveyor belt 13 may come into contact with the sliding bed 2 depending on the weight thereof, but the frictional resistance between the conveyor belt 13 and the sliding bed 2 is reduced by the introduction of pressurized air. At the same time, the carrier roller 3 arranged in the middle of the sliding bed 2 rotates along with the traveling of the conveyor belt 13 to assist in carrying the baggage A, so that the baggage A is carried smoothly. Although the top surface of the carrier roller 3 is slightly higher than the sliding bed 2, there is almost no step due to the conveyor belt 13 trying to float by the pressurized air. There are few things to get on, and it is transported stably.

Regardless of the presence or absence of the baggage A placed on the conveyor belt 13, the frictional resistance with the sliding bed 2 is greatly reduced. The traveling speed of the belt 13, that is, the transport speed of the baggage A, could be increased to 300 m / min, which is twice the conventional speed in the case of the above embodiment.

FIG. 7 is a partially enlarged longitudinal sectional view showing another embodiment of the belt conveyor device of the present invention.

In the belt conveyor device 1 'of this embodiment,
Conveyor belt 13 from both sides of sliding bed 2
A cover member 22 having a substantially L-shaped distal end bent in a U-shape is attached to the upper end of the side wall of the duct 4 with a bolt 22a so as to wrap both side edges of the duct 4. For this reason, the escape of the pressurized air blown out from the air blowing holes 2a of the sliding bed 2 to the conveyor belt 13 from both sides of the conveyor belt 13 to the outside is suppressed to a minimum, which is effective for floating the conveyor belt 13. Work on. In addition, since the position of the blowing hole 2a is set so that the blowing of the pressurized air is performed at the center of the sliding bed 2 as shown in FIG. 6, the conveyor belt 13 is rubbed at the tip of the cover member 22. There is little wear.

While the embodiment of the belt conveyor device for carrying baggage of the present invention has been described above, the present invention can be implemented as follows.

(A) The installation interval of the carrier roller 3 is determined by the elasticity of the conveyor belt 13, and at least when the compressed air is blown out when the baggage A is not conveyed,
The interval is such that the conveyor belt 13 does not contact the sliding bed 2. This interval is 500 mm in the above embodiment.
However, depending on the elasticity of the conveyor belt 13, 150
It can be expanded to about 0 mm.

[0030]

(B) In addition to being used in a passenger baggage processing system at an airport, the present invention can be used for transporting work and luggage in factories and warehouses, for example. In this case, the sliding bed 2 may be used depending on the type, size, shape, etc. of the transferred object.
Of the carrier roller 3 in the longitudinal direction, the supply amount of the pressurized air, and the like can be set.

[0032]

As is apparent from the above description,
The baggage conveyor belt device of the present invention has the following excellent effects.

(1) The sliding friction between the sliding bed and the conveyor belt is reduced by introducing pressurized air between the sliding bed and the conveyor belt, and the sliding resistance of the conveyor belt is determined by carrier rollers arranged at predetermined intervals in the longitudinal direction of the sliding bed. It helps to transport baggage in a stable state and at high speed because it reduces the amount of heat generated between the sliding bed and the conveyor belt, prolongs the life of the conveyor belt, and increases the length of the machine. However, it is not necessary to greatly increase the driving force. In addition, the conveyor belt on the sliding bed does not completely float, and blows out the amount of pressurized air that reduces sliding friction resistance.Therefore, the amount of pressurized air is significantly larger than when the conveyor belt is completely floated. It is not necessary to increase the driving force of a blower or the like for supplying pressurized air.

(2) In the apparatus according to the second aspect, the pressurized air can be almost uniformly introduced into the continuous duct below the sliding bed from one pressurized air source, and the pressurized air can be transferred to the conveyor belt. And the sliding friction between the upper traveling portion of the conveyor belt and the sliding bed can be reduced substantially uniformly over the entire length.

(3) In the device according to the third aspect, since the belt is made of a resin, it can be easily wiped off even if dirt or the like adheres thereto, and the driving device is lighter in weight than a rubber conveyor belt. Driving force can be reduced. In addition, since both side edges of the conveyor belt are wrapped by the cover member, the compressed air blown to the lower surface of the conveyor belt is difficult to escape to the outside, and the sliding friction of the conveyor belt is effectively reduced with a minimum amount of compressed air it can.
