Description of the invention (彳) Background of the invention The present invention relates to mobile walkways installed in public facilities such as airports, railway stations, etc., and is particularly related to transportation in two opposite directions. User's Moving Aisle "As far as the actual moving aisle is concerned, there is a moving aisle that includes sprockets rotatably mounted on the left and right sides of the moving aisle at one end and the other end of the moving aisle. An endless chain engaged on the sprocket on each side, and a number of pallets that can carry the user and engage with the endless chain on the left and right sides to bypass or circulate by rotation of the sprocket. In this moving walkway, users are transported from one end of the moving walkway to the other end by pallets moving along the circulation path above or on the shipping side, while pallets moving along the circulation path below or on the turning side are not helpful For user transport. In this moving walkway, users cannot be transported in two opposite directions at the same time. JP — B — 5 6_2 5 7 discloses another type of moving walkway. As shown in FIGS. 1 to 5, the moving walkway disclosed in this announcement includes a receiving groove 1 0 extending in the extending direction of the moving walkway. The guide rail 1 0 2 is disposed on the opposite side of the groove 1 〇1 on the upper surface of the upper portion of the guide rail 1 〇2 and has a guide plate 1 0 3 running in the extending direction of the moving walkway. 4 ′ can support the user's support plate 105, and is rotatably supported on the left and right bottom portions of the support plate 105 through the receiving seat 1 06 to become a steel ball 1 that can roll along the running groove 103. 0 7, and has a thread 1 009 and is arranged in the groove 1 0 1 to become the standard of the Chinese paper (CNS > A4 specification (210X297 mm)) applicable to moving this paper scale nn I ..... i I- 1 n.

The spiral shaft 108 can be made of steel wires bundled together to have flexibility. The helical shaft 108 has its threads 10 and 9 having a shorter pitch and a longer pitch portion S and L, respectively. The segment S having the shorter pitch is configured close to the user to mount or leave the pallet. Part of the screw rod 108 is connected to the drive shaft of the motor 110, and the other end is rotatably supported by the bearing 111. Each A supporting plate 105 is formed with grooves 11 2 extending in the moving direction of the supporting plate 105 respectively at the bottom portion of the supporting plate near the front and rear ends. Each groove 1 1 2 passes through the groove 1 1 2 The extended shaft 1 1 3 supports the upper part of the support frame 1 1 4 so that the frame 1 1 4 moves forward and backward in the moving direction of the pallet 105. Each support frame 114 is rotatable at the bottom part of the front and back respectively. The steel balls 1 1 5 are supported on the ground so that the steel balls 115 contact the threads 1 0 9 of the screw shaft 108. In this moving walkway, the action of the motor 1 1 0 causes the support frame 1 1 4 to cooperate with the rotation of the screw shaft 108 It is pushed in the feeding direction of the thread 109, which causes the pallet 105 to move. The velocity of the pallet 105 is close to the access position. Thread 1 0 9 is slower at the portion S with a shorter pitch, and increases at the portion L of the thread 10 9 with a longer pitch between the entry and exit positions. At each pallet 10 5 from the thread 1 0 9 Part S with a shorter pitch is transferred to the thread 1 0 9 Part L with a longer pitch is transferred to the thread in the opposite direction or the paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) m ^ i ^^^^ 1 nn (please read and read the note on the back before filling in this page) -5-Printed by A7 _B7 printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economy The supporting frames 1 1 4 on the plate 105 are moved horizontally along the axis 1 1 3 to adjust the gap between the supporting frames 1 1 4 according to the change in the pitch of the threads 109. Due to its flexibility, the helical shaft 108 can be bent to bend the moving path of the pallet 105. Therefore, it can be designed so that a number of pallets 105 can be bypassed or circulated by the circular configuration of the spiral shaft 108 as shown in FIG. 5. However, in fact, it is difficult to manufacture a spiral shaft 108 having good flexibility, and therefore the spiral shaft 108 is not suitable for practical use. It is not easy to loop. Configure the screw shaft 108 to make the pallet 105 go around or circulate. In addition, in the moving walkway disclosed by J PB — 5 6-2 5 7, the adjacent pallets 105 in the moving direction do not contact each other '. Therefore, a fence mechanism or the like must be provided for each pallet 105. To prevent users from falling. The present invention has been made in view of the above, and its object is to provide a moving walkway that can simultaneously transport users in two opposite directions and in a safe manner. According to the invention, in the moving walkway according to the present invention, a plurality of pallets are arranged on a circular rail for detour or circulation, and each circular rail has two linear sections and two semicircular sections combined endlessly and horizontally. . The screw mounted on the linear section of the rail rotates to move in one direction a pallet having a moving roller engaged with the screw groove of the screw.

Description of the invention U) The parts are pulled by the moving pallet and screw. On the semi-circular section of the rail, each pallet is contacted by the front end of the next pallet at a protruding member on its lower surface. The pallet at the semi-circular section of the rail is pushed forward by the moving pallet and screw on the linear section of the rail. ~ The front end of each pallet is embedded below the rear end of the previous pallet, thus forming a continuous walkway surface. The front end of each pallet may have a recess, and the recess may be fitted on the protruding member of the previous pallet. This ensures that the rear end of each pallet has a positive engagement on the semi-circular section of the rail with the front end of the next pallet. The screw can be arranged on the part of the linear section of the rail closer to the semi-circular section, the pitch of the thread groove on the screw is shorter on the part of the semi-circular section closer to the rail, and It is longer on the part of the semi-circular section away from the rail. This reduces the moving speed of the pallet on the portion of the linear section of the rail closer to the semi-circular section, and increases the moving speed of the pallet on the middle portion of the linear section of the rail. An additional screw for moving the pallet may be separately disposed at a middle portion of the linear section of the rail to reduce a pulling force applied to a string mechanism interconnecting adjacent pallets. Each pallet can be provided with an inclination-angle compensating roller that can roll on the lower surface of the guide rail. These rollers incline the pallet moving from the linear section of the rail to the semi-circular section, so that the pallet The back end jumps off the front end of the next pallet. These rollers release the forward tilt of the pallet that moves from the semi-circular section of the rail to the linear section, so that the rear end of the pallet overlaps the front end of the next pallet.

As a result, the armrest 77L bypasses or circulates in synchronization with the movement of the pallet 3. % The operation mode of the moving walkway shown in FIGS. 6 to 25 is described below. In this embodiment, the screws 16 and 24 are rotated by the motors 19 and 4 8 to cause the moving rollers 18 engaged with the spiral grooves 16 a and 2 4 a to correspond to the screws 16 and 2 4 The direction of rotation is conveyed, which moves the pallet 3 along the linear sections 1A and 1B of the rail 11. In this case, the moving directions of the pallet 3 on the linear sections 1 A and 1 B of the rail 11 are opposite to each other. Therefore, the user can be transported in two opposite directions at the same time by this single moving walkway. Among the pallets 3 on the linear sections 1A and 1B of the rail 11, those pallets 3 that are not engaged with the spiral grooves 16 a and 2 4 a by the moving rollers 18 are formed by the mating screws 16 and 24. The front support plate 3 which is moved by rotation is pulled through the elastic buffer mechanism 25 and the chain 22.

In this case, the rear end of the pallet 3 overlaps the front end of the next pallet 3. Therefore, many users can be transported in a safe manner. The moving speed of the pallet 3 moves with the moving roller 18 to the access section S1, the low-speed section M1, and the high-speed section L1 of the spiral groove 16a in order of the paper size in accordance with the Chinese standard (CNS) A4 (210X297).

The description of the invention (23) increases and decreases with the moving roller 18 to the high-speed section L1, the low-speed section M1, and the access section S1 of the spiral groove 16a. Therefore, at the opposite ends of the linear sections 1 A and 1 B of the rail 11, the pallet 3 moves at a low speed, so that it is easy for a user to get on or off the pallet 3. At the middle portion of the linear section 1A: ^ '1 B of the rail 11, the pallet 3 where the user is located can be moved at high speed. When each pallet 3 starts to be pulled by the previous pallet 3, an excessive pulling force may be applied to the chain 22 between adjacent pallets 3. Such a possible excessive tension is released by the elastic buffer mechanism 25. As a result, deformation of the chain 22 which may be caused by repeated application of excessive pulling force can be prevented, thereby reducing any impact on the user on the pallet 3. In addition to the screw 16, the screw 24 is also disposed at the middle portion of the linear sections 1 A and 1 B of the rail 11. Therefore, any pulling force exerted on the chain 22 can be further reduced, and it is achieved that the linear sections 1 A and 1B of the rail 11 can be designed to have a longer length. Releasing the pulling force applied to the chain 22 can suppress any elongation of the connecting rods constituting the chain 22 and any wear of the pins that interconnect the connecting rods '' Printed by the Central Standards Bureau of the Ministry of Economic Affairs -—1 11 i ^ im I n 1 ^ 1 ^^ 1 —ϋ 11 (Please read the precautions on the back before filling this page) When the pallet 3 is close to the linear section 1A of the rail 11, it is closer to the semi-circular area When the part of segment 1 D or the linear segment 1 B of the rail 11 is closer to the semicircular segment 1 C, the overlap between the rear end and the front end of the adjacent pallet 3 is due to the spiral groove 16 The high-speed section L1 and low-speed section M1 of a increase with the difference in the pitch from the in-out section S 1, so the distance between the pallets 3 is reduced. 0 When the pallet 3 enters directly below the movable step 6 3, it enters.

Description of Invention (25) The rear end of each pallet 3 overlaps with the front end of the next pallet 3, and The protrusion 3e of the plate 3 re-engages with the groove 3e of the next holding plate 3. As described above, according to the moving walkways shown in Figs. 6 to 25, users can be safely transported in opposite directions. Fig. 26 shows another embodiment of the configuration of the rail 11 used in the moving walkway of the present invention. Each track 11 includes linear sections 1 Α and 1 Β arranged horizontally and in parallel to each other, respectively, following the quarter sections IE, IF, 1G, and 1H of the ends of the linear sections 1 Α and 1 Β, respectively. The opposite end is connected to the short linear section 1 K of the quarter sections 1 E and 1 G, and the short end is connected to the short linear section 1 L of the quarter sections 1 F and 1 Η. In this way, the distance W between the long linear sections 1 Α and 1 Β of the rails 1 1 transported in different directions of the pallet 3 can be increased. It must be understood that the moving walkway according to the present invention is not limited to the above-mentioned embodiments, and various changes and modifications can be implemented without departing from the scope of the present invention. For example, in a case where the linear sections 1 A and 1 B of the rail 11 are not long, the screw 16 may be disposed on almost the entire length of each of the linear sections 1 A and 1 B to move the pallet 3. In the case where the linear sections 1 A and 1 B of the rail 11 are very long, a plurality of screws 24 can be installed at the middle portion of the linear sections 1 A and 1 B to reduce the pulling force applied to the chain 22 . The above-mentioned elastic buffer mechanism 25 has a spring member 29, but it can utilize gas pressure or liquid viscous resistance.

Description of Invention (26) But The mechanism 25 may also be installed at each of the opposite ends of the chain 22. In FIGS. 6 and 7, the guide rail 12 is shown to have its end slightly extended toward the center of the linear segment 1 A or 1 B beyond the end of the semi-circular segment 1 c or 1 D, but the guide rail 12 may face the linear segment. The center of 1 A or 1 D extends further than the positions shown in FIGS. 6 and 7 or may be slightly shorter than the positions shown in FIGS. 6 and 7. As described above, according to the moving walkway of the present invention, the following excellent effects can be obtained. (1) In the moving walkway according to any one of the items 1 to 10 of the scope of the patent application, a plurality of pallets are configured to detour or circulate on the circular rails each having two linear sections. The screws used to move the pallets are mounted on linear sections of the rails and adjacent pallets are interconnected using a string mechanism. As a result, the moving direction of the pallet in the linear section is opposite to the moving direction in the other linear section of the rail, so the user can be transported by a single moving aisle in two opposite directions simultaneously. (2) The front end of each pallet is embedded below the rear end of the previous pallet to form a continuous walkway, so that a large number of users can be transported in a safe manner. (3) The recess can be set at the front of each pallet to fit in front A protruding member of a pallet, which ensures that the front end of each pallet has a positive engagement with the rear end of the previous pallet on the semi-circular section of the rail "(4) the screw may have A spiral groove with a short pitch at the part of the semicircular section of the bar and a longer pitch at the part far from the semicircular section, so that the moving speed of the pallet is in the linear region of the rail The section is slower near the semi-circular section, and the Chinese paper size in the linear section of the rail is used in the Chinese national kneading rate {CNS) A4 specification (210X297 mm)-I — I-_ --* I---It—- (Please read the precautions on the back before filling out this page) -29- A7 B7 V. The description of the invention (27) is added in some places. Therefore, on the portion of the linear section of the rail closer to the semi-circular section, the user can easily board or leave the pallet. (5) An additional screw for moving the pallet may be separately provided at the middle portion of the linear section of the rail, which may release any pulling force applied to the string mechanism interconnecting the adjacent pallets. ~ (6) Each pallet can be provided with an inclination angle compensating roller that can roll on the lower surface of the guide rail, which inclines the pallet moving from the linear section of the rail to the semi-circular section, so that The back end of the pallet jumps off the front end of the next pallet. This facilitates the movement of the pallet over a semi-circular section of the rail. (7) The steps can be arranged at each of the access positions where the user can board or leave the pallet. The step has comb teeth that can fit in longitudinally extending grooves on the upper surface of each pallet. This makes it possible to remove foreign objects in the grooves of the pallet by combing the teeth. (8) The step can be vertically moved by the tracking mechanism according to the upper surface of the pallet near the position where the step is arranged. This prevents the comb teeth from contacting the bottom of the groove of the pallet, thus preventing the abrasion of the comb teeth.
