The present invention relates to a variable speed passenger conveyor, and more particularly, to a variable speed passenger conveyor for carrying a passenger on a pallet of variable speed.

In a passenger conveyor that assists passengers in the horizontal movement, a variable speed type that speeds up the intermediate portion and relatively slows down the lift end for safety is required because the transportation takes a long time when the transportation becomes long. Many have been devised.

The variable speed passenger conveyor is divided into belt conveyors and rollers with different speeds, the pallets of passengers are horizontally slid to make the speed in the inclined direction variable, and the space between the pallets can be expanded and adjusted. There is a way to realize. The changing method is disclosed in, for example, French Patent No. 1583906 or Japanese Patent Laid-Open No. 6-156693, and the horizontal sliding method is disclosed, for example, in Japanese Patent Laid-Open No. 47-220.

In addition, there are a number of methods for extending the pallet spacing. In addition to Japanese Patent Application No. 46-7057 and Japanese Patent Application Laid-open No. 4-209191, an expansion link mechanism is used to expand or shorten the pallet spacing. A method of constructing a plate that stretches and deforms the pallet itself in addition to Japanese Unexamined Patent Publication No. 50-78080, and a method of drawing out overlapping portions of the pallet other than Japanese Unexamined Patent Publication No. 58-89579, respectively. have.

Regarding handrails, there is British Patent No. 1286453 as handrails integrally installed with pallets.

Moreover, in a stepped passenger conveyor, it is used to secure the boarding area of a wheelchair by making three pallets horizontally, or two horizontally and inclining the previous one.

Hereinafter, various problems to be solved by the present invention will be described.

The first problem to be solved by the present invention is a response to a walking walker.

The object of the present invention is to provide a variable speed passenger conveyor for use in a long distance horizontal movement, not only for general pedestrians, but also for pedestrians such as wheelchair users and the elderly, people with heavy belongings such as suit cases, and the like. It is in reducing labor of movement.

However, among the above-mentioned prior arts, a shift type using a belt cannot be used in a wheelchair, and a method of stretching or deflating the pallet or drawing out overlapping parts also includes pallets within the range required for wheelchair riding. The use of a wheelchair is not considered, such as a deformation | transformation of, and it is not suitable for the installation purpose of this invention.

Accordingly, an object of the first invention of the present invention is to provide a pallet-type variable speed passenger conveyor that is capable of responding to a walking walker, especially a wheelchair user.

It is also an object of the first invention of the present invention to provide a variable speed passenger conveyor in which the pallet is integrated as long as the wheelchair is in the boarding range.

Next, the 2nd subject of this invention is solving the problem of the fixed floor of the clearance gap which arises between pallets.

In order to realize a passenger conveyor that carries passengers on pallets and transports them by variable speed, it is necessary to expand and contract the pallets. At this time, however, in the prior art, all pallets are connected to the front and rear pallets, and the connection part is stretched to cope with the speed change, but the speed increase ratio is limited by the ratio of the length of the stretchable part inserted into the pallet and the length of the pallet itself. In general, there is a problem that only a speed increase ratio of less than twice can be obtained.

Therefore, in order to obtain a larger speed increase ratio, it is necessary to generate a gap between pallets. In variable speed passenger conveyors with gaps between pallets, pallets generally appear continuously under the floor of the boarding station to become passengers' boarding areas, and are accelerated by widening the gaps at the intermediate section and with the pallets before and after By shortening the interval, the pallet is brought into contact with each other to eliminate the gap, and the operation of suctioning under the floor of the bus stop is repeated. However, if the floor surface of this pallet clearance is fixed, when passengers or belongings fall in the clearance gap, it will collide with the pallet which speeded up at the speed of several times of the boarding point part, and will be in a dangerous state.

In this regard, in the above-mentioned British Patent No. 1286453, a pallet for changing to a high speed main conveyor runs on the conveyor but is not considered to drive the pallet gap. In addition, as the pallet shifts, the conveyor is at a constant speed, and the speed of the gap does not correspond to the speed of the pallet.

It is therefore an object of the second invention of the present invention to provide a means for driving the floor surface of the pallet gap in response to the speed change of the pallet.

Moreover, the objective of the 2nd invention of this invention is providing the variable speed passenger conveyor which improved the safety | security regarding the floor surface of a pallet clearance.

Next, a third object of the present invention is to avoid the danger associated with the walking of passengers on a variable speed passenger conveyor.

In a passenger conveyor with no speed change, pallets are connected without gaps and constitute a floor surface that moves as a whole, so that passengers can walk on it, and the use of such walking is widely used. have.

However, in a variable speed passenger conveyor in which a gap is formed between pallets, the gap in the intermediate portion generated by acceleration is a temporary area and disappears by deceleration of the discharging end. For this reason, if the gap is filled by the passenger walking, there is a risk that the passenger's standing space is lost when the gap disappears at the discharging end, and the passenger may fall at once. In the above-mentioned prior art, the problem concerning walking is not considered.                         

It is therefore an object of the third invention of the present invention to provide a variable speed passenger conveyor that is effective for returning passengers or dropped belongings to the pallets to pallets.

It is also an object of the third invention of the present invention to provide a variable speed passenger conveyor effective for reducing the walking of passengers on a passenger conveyor.

Next, the 4th subject of this invention is to solve many problems according to the clearance gap which arises between pallets.

For example, in a variable speed passenger conveyor where gaps are created between pallets, there is a risk that passengers or belongings are inserted between pallets when pallets couple the gaps at the distal end. In addition, as described above, passengers and belongings may fall from the pallets to the gaps, and it is also necessary to notify the passengers where the pallets move as a whole and where the gaps occur when boarding.

In the Japanese Laid-Open Patent Publication No. 58-89579, an example is described in which the area where the pallet surface overlaps and the area that does not overlap or are shown as projections, but there is no consideration regarding the above problems due to the pallet gap.

In the stepped passenger conveyor, it is also considered that the step between the pallets is a gap. However, in the present invention, the head of the pallet and the comb teeth provided at the step are always in contact with each other, and the pallet is separated or combined. This is different from the variable speed passenger conveyor.

Therefore, the objective of the 4th invention of this invention is to improve the safety at the time of pallet joining.

It is a further object of the fourth invention of the present invention to provide a variable speed passenger conveyor that is suitable for preventing passengers or belongings from falling into the pallet gap.

It is a further object of the fourth invention of the present invention to provide a variable speed passenger conveyor in which passengers or dropped belongings dropped into the pallet gap can be easily returned to the pallets.

Next, the 5th subject of this invention is to solve the problem by enlargement of a pallet.

As described above, since the purpose is to be able to ride a wheelchair on a pallet with a variable speed passenger conveyor, the effective boarding portion of the pallet needs at least 1000 mm or more. If it consists of one pallet, it will become large and heavy, and manufacturing, construction, and repair will also become inconvenient. In addition, even when the pallet is inverted in the moving direction, if the pallet is large, it is necessary to widen the space required for reversal, thereby increasing the depth of the passenger conveyor itself. This is also disadvantageous in civil engineering work at the time of installation.

Accordingly, an object of the fifth invention of the present invention is to provide a joint pallet suitable for a variable speed passenger conveyor.

Moreover, the objective of the 5th invention of this invention is to suppress the increase of the weight of the unit pallet of a variable speed passenger conveyor.

Moreover, the objective of 5th invention of this invention is to suppress the depth of a variable speed passenger conveyor.                         

Furthermore, a fifth object of the present invention is to facilitate the manufacture, construction, installation and repair of variable speed passenger conveyors.

Next, the 6th subject of this invention is solving the problem of the side gap peculiar to the pallet type variable speed passenger conveyor with a gap.

In order for the pallet to pass through, a side gap as much as the thickness of the pallet is formed between the bottom surface of the pallet and the cover of the pallet in the side of the pallet, and passengers and possessions who have got off the pallet gap are drawn in this gap. There is a possibility of quality. This prior art does not consider this point.

It is therefore an object of the sixth invention of the present invention to provide a shield for the lateral gap.

Moreover, the objective of the 6th invention of this invention is to provide the detection means which roll in to a side gap.

Moreover, the objective of the 6th invention of this invention is to improve the safety | security regarding a side gap.

Next, a seventh subject of the present invention is to solve the problem of escape at the time of stopping the passenger conveyor in a long distance passenger conveyor.

In passenger conveyors, it is usually necessary to be configured so as not to travel between the passenger conveyor interior and the external passage except for the lift section. However, if the passenger conveyor has stopped for some reason, the passenger in the passenger conveyor must escape outside the passenger conveyor, but if the passenger conveyor is very long, it is necessary to walk long distances inside the narrow passenger conveyor for this escape. There is a problem saying no.

It is therefore an object of the seventh invention of the present invention to provide a means for escaping to an outer passage in the middle of a passenger conveyor in an emergency.

Moreover, the objective of the 7th invention of this invention is to improve the safety in the normal time of this emergency escape means.

(Example)

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 20.

In addition, since this invention is comprised by the combination of the several invention item related to each other in order to implement a variable speed passenger conveyor, it describes corresponding to the invention item in the description of this embodiment.

First, the structure and arrangement of the variable speed passenger conveyor according to the present embodiment will be described with reference to Figs.

1 is a perspective view showing an outline of a linear variable speed passenger conveyor.

In the same figure, 1 is a pallet for boarding and transporting a passenger, 2 is a boarding plate for passengers to start boarding, 3 is a pallet (1) mounted thereon and a pallet (1) from the boarding end to the middle of the variable speed passenger conveyor. Acceleration rollers for accelerating the speed of 4, the high-speed conveyor for transporting the pallet (1) at high speed, mounted on the pallet (1), 5 is the high-speed conveyor for transporting the pallet (1) at high speed, from the middle to the end A deceleration roller that decelerates the speed of the pallet 1, 6 is a loading stop plate where passengers get off from the pallet 1, 7 is a pallet railing, 8 is a pallet railing compartment, 9 is a guard, and 10 is a safety guard emergency exit. .

As shown, in this linear variable speed passenger conveyor, pallets 1 continuously appear below the boarding plate 2 to become passengers' passenger compartments, and the interval is accelerated by widening the interval in the section of the acceleration roller 3. Thus, the high speed section corresponding to the high speed conveyor 4 which occupies most of the passenger conveyor is moved, and the interval between the front and rear pallets is further shortened in the section of the deceleration roller 5 at the lower stage, and the pallet is brought into contact with the clearance. To eliminate, the operation to be sucked down the loading dock plate 6 is repeated. By varying the interval of the pallet, the speed at the intermediate portion can be made faster than the speed at the lifting end.

As described above, in the present embodiment, an acceleration roller 3 having a sequential speed becomes higher, a high speed conveyor 4 moving at a constant speed, and a deceleration roller 5 having a sequential speed lowered below the pallet 1. Is arranged, the pallet 1 moves on these acceleration rollers 3, the high speed conveyor 4, the reduction rollers 5 by frictional force, and the passengers who ride on the pallet 1 move. You can do it.

Here, the pallet gap surface driving means is constituted by the acceleration roller 3, the high speed conveyor 4, and the reduction roller 5, and at the same time the pallet driving means is the acceleration roller 3 corresponding to the pallet acceleration means. , A high speed conveyor 4 corresponding to the pallet high speed driving means, and a reduction roller 5 corresponding to the pallet deceleration means. This embodiment shows an example in which both the pallet driving means and the pallet gap surface driving means are configured.

Since the pallet driving means and the pallet gap surface driving means are used together, in order for the pallet to be driven by the friction of the pallet gap surface driving means, the speed of the pallet becomes equal to the speed at each position of the pallet gap surface driving means, And the speed of the pallet gap surface can be synchronized.

In this way, even if a gap occurs due to the speed change between the pallet and the pallet before and after the pallet, the pallet gap surface is driven at a speed synchronized with the pallet, so that the passengers get off at the bottom surface of the pallet gap. In addition, even if the passenger's belongings fall, the safety of the pallet clearance can be ensured without colliding with the pallet at a large speed difference. In short, in the present embodiment, the pallet gap surface driving means serves as a safety device of the variable speed passenger conveyor.

As described above, according to the present embodiment, by using both the pallet driving means and the pallet gap surface driving means, it is possible to synchronize the speed between the pallet and the pallet gap without using a complicated mechanism.

Further, according to this embodiment, by using both the pallet driving means and the pallet gap surface driving means, the configuration is simplified, and the low cost variable speed passenger conveyor can be provided by using the mechanism.

Moreover, according to the present embodiment, even when the passenger gets off the pallet clearance or the passenger's belongings fall, the pallet does not collide with the pallet at a large speed difference, and the safety can be improved.

In addition, the pallet 1 is comprised by connecting several sheets (3 sheets in this embodiment) so that a wheelchair can ride. Within the range of passenger boarding, a gap is formed between the pallet and other pallets due to the speed change of the passenger conveyor, but the gap is not generated between the pallets of the pallets. One wheelchair is not affected by the gap during movement on a passenger conveyor.

Here, the size of the wheelchair varies depending on the technology used for the wheelchair (manual / electric, etc.), the environment in which it is used, or the age. The main purpose of the present invention is to prepare a pallet in a size capable of riding a wheelchair, and as a goal of the size, to ensure that a general thing according to a standard for defining a wheelchair, such as the Japanese Industrial Standard, is capable of riding length / width.

According to this embodiment, the wheelchair is provided with a size sufficient for boarding, and since there is no gap in the pallet due to the speed change, it is easy to use in the wheelchair.

Further, according to the present embodiment, since the pallets appear horizontally and continuously at the boarding point, even when using a wheelchair, the boarding can be carried out without stopping the whole and degrading the overall efficiency.

In addition, the pallet 1 is provided with the pallet railing 7, and this pallet railing 7 appears from the pallet railing accommodating part 8 in a boarding point, and is stored in the pallet railing accommodating part 8 in a getting off place.

Moreover, the side of the passenger conveyor is provided with a protective measure 9 which distinguishes between the passenger conveyor and the general aisle and prevents contact of passengers or objects in or outside the passenger conveyor, or coming and going in and out of the passenger conveyor. The protective guard 9 is provided with a protective guard emergency exit 10 at an interval. The protective guard emergency exit 10 normally locks the lock, and when the passenger conveyor stops, the lock is released and becomes an emergency exit in the middle of the long-distance passenger conveyor. When the passenger conveyor stops, the protective guard emergency exit 10 exits from the pallet 1 at the clearance gap and passes between the pallet railings 7 and exits to the protective guard emergency exit 10. Therefore, in the belt type handrail structure used in the passenger conveyor which does not cause the speed change in the related art, it is impossible to provide an emergency exit, but according to this embodiment, the clearance between the pallet railing 7 and the pallet 1, Emergency passages are formed by the combination of the side fixed protective measures 9 and the protective measures emergency exit 10.

In addition, even if the interval of any protective guard emergency exit 10 cannot be exactly overlaid with the pallet railing 7, the protective guard emergency exit 10 is a constant of the interval of the pallet and the corresponding position of the next pallet in a high speed section. By arrange | positioning so that it may not become a ship, it can always escape using any one protective guard emergency exit 10 at the time of stopping of a passenger conveyor.

As shown, the pallet 1 emerges continuously under the platform plate 2 to become the passenger's boarding area, and is accelerated by widening the gap with the acceleration roller 3 to occupy most of the passenger conveyor. The high-speed section corresponding to (4) is moved, and the interval between the front and rear pallets is further shortened in the section of the deceleration roller 5 of the lower stage, and the pallet 1 is brought into contact with each other to eliminate the gap, and the platform Is sucked down).

Further, the pallet 1 sucked down of the loading dock plate 6 is rotated by the terminal gear 12, mounted on the return side conveyor 13, and returned to the bottom of the boarding point portion, and the second terminal gear 12 The cycle of rotating by) and appearing in the boarding area part is repeated.

As an example, the speed at this time is 30-50 m / min in the initial velocity of a lifting edge part, and the intermediate part is about 2 times-4 times. In addition, the length of each section is about 5-10m before and after the speed of the roller 3 for acceleration and the speed reduction roller 5, and the range of the high speed conveyor 4 is 100-2000m by the magnitude | size of a speed change and the acceleration / deceleration speed. . In the variable speed passenger conveyor, the length of the intermediate high speed conveyor 4 is overwhelmingly long compared with other sections, and therefore, in the drawings of the present embodiment, it is assumed as a necessary component for explaining the present embodiment, and the ratio of the length and the like. In particular, it is assumed that the necessary part is enlarged or reduced without appreciation. In addition, illustration of the element which is not directly related to this invention, such as the technique normally used in a passenger conveyor, is abbreviate | omitted.

Position detectors, 19-1 and 19-2 of the position detectors 12 are respectively installed in combination at predetermined positions near the It is a light emitting part and a light receiving part. In addition, in the same figure, the part of code | symbol same as the code | symbol shown in FIG. 1 represents the same part.

Here, the position detector 12 is disposed at a predetermined position by a sufficient number to realize the present invention.

In the same figure, the pallet 1 is driven in the advancing direction by friction on the reduction roller 5, but since the transfer of the frictional force may cause slippage, a part of the reduction roller 5 is controlled. It is also possible to use (14) for correction of slip.

The rotational force of the main motor 15-1 is transmitted to the high speed conveyor drive shaft 16-1 through the common drive chain 17-1 to drive the high speed conveyor 4. At the same time, the rotational force of the main motor 15-1 is transmitted to the deceleration roller drive shaft 16-2 via the common drive chain 17-1 and the acceleration / deceleration gear 18, and furthermore, the deceleration roller drive. The reduction roller 5 is driven through the chain 17-2. At this time, the acceleration / deceleration gear 18 is a high-speed conveyor 4 at a gear ratio corresponding to the installed position so that the acceleration roller 3 or the reduction roller 5 rotates at different speeds at a predetermined ratio with respect to each position. To change the speed. The control roller 14 is driven by the control motor 15-2, the control drive shaft 16-3, and the control roller drive chain 17-3, and is independent of the rotational speed of the main motor 15-1. Controllable. Further, since the light generated by the light emitting portion 19-1 reaches the corresponding light receiving portion 19-2 when the pallet 1 is not present at the position, and is blocked when the pallet 1 is present, the position detector (19) can measure the position of the pallet 1 from the light reception state of the light in the light receiving part 19-2.

Moreover, since the variable speed passenger conveyor of this embodiment can be comprised so that direction reversal is possible, the structure of a boarding point part can be made into the structure symmetrical with a loading dock part. On the contrary, it is also possible to install a motor only on one side and to make it asymmetrical, and to make a spring structure for applying tension to the common drive chain 17-1 on the opposite side as necessary.

As shown in the figure, irregularities are formed on the surface of the pallet 1, and are configured to engage with the comb teeth provided at the ends of the unloading plate 6, so that even if there is a falling object, it is possible to lift it up.

The transverse movement of the passenger's passenger conveyor is regulated by a pallet railing 7 on the pallet 1, a side cover 11 and a guard 9. However, in this range, it may be possible to get off at the pallet gap, so that the width of the acceleration roller 3, the high speed conveyor 4, and the reduction roller 5, which are the pallet gap surface driving means, is at both ends of the side cover 11. Required to take). In addition, since the pallet 1 needs wheels to support the load on the pallet and the pallet itself, the width of the acceleration roller 3, the high speed conveyor 4, and the reduction roller 5 is It is shorter than the space | interval of the wheel of the pallet 1.

The device for driving the reduction roller 5 has a reduction roller drive chain 17-2 and an acceleration / deceleration gear 18 installed below the pallet 1 within the width of the pallet 1, The roller drive shaft 16-2 reaches the outside through the wheel of the pallet 1 and the guide rail 204 which supports it, and the common drive chain 17-1 carries the wheel, the guide rail 20, and illustration. The main motor 15-1 is reached by passing through the side of the terminal gear 12 that is not. On the contrary, the drive chain 17-4 of the return side conveyor 13 reaches the main motor 15-1 through the width of the pallet so as not to disturb the pallet railing 7.

The light emitting portion 19-1 and the light receiving portion 19-2 of the position detector 19 have a side cover 11 of a gap between the deceleration roller 5 and the wheel of the pallet so as to detect the pallet 1 position. ) And beneath the bottom surface 21.

Next, a control system of the variable speed passenger conveyor according to the present embodiment will be described with reference to FIGS. 5 to 10.

5 is a block diagram showing an outline of a control system of a variable speed passenger conveyor.

In the same figure, 22 is a control apparatus, 23 is a voltage-frequency control part, 24 is a start switch, 25 is a stop switch, 26 is an abnormality detector, and 27 is an abnormality notification apparatus. In addition, in the same figure, the part of code | symbol same as the code | symbol shown in FIG. 3 represents the same part.

As shown in the drawing, the control device 22 is composed of an operation control unit 22-1, a speed command generation unit 22-2, and an abnormality determination unit 22-3, and receives the output of the position detector 19. The operation method is determined by the operation control unit 24-1, the speed command is calculated by the speed command generation unit 22-2, and the calculated speed command is given to the voltage / frequency control unit 23. The voltage / frequency control unit 23 generates and outputs a voltage and / or frequency necessary for the main motor 15-1 and the control motor 15-2 according to the given speed command. Receiving this, the main motor 15-1 drives the high speed conveyor 4, the terminal gear 12, the return side conveyor 13, or changes the speed by the acceleration / deceleration gear 18, and accelerates the rollers 3 for acceleration. ), The reduction roller 5 is driven. In addition, the control motor 15-2 drives the control roller 14.

Moreover, the signal from the start switch 24, the stop switch 25, and the signal from the abnormality detector 26 are input to the control apparatus 22, and the operation control part 22-1 and the abnormality determination part 22-3 are received. Is processed in In addition, the abnormality detector 26 includes an emergency stop switch 26-1, a boarding point and a parking lot plate rolling detector 26-2, a pallet railing accommodating portion rolling detector 26-3, and a side rolling detector 26. -4) Each device of the protective device emergency exit detector 26-5 is provided, and when an abnormality occurs, the abnormality notification device 27 is also output.

Next, the processing procedure of the main program 100 in the control apparatus 22 shown in FIG. 5 is demonstrated using the flowchart shown in FIG.

In addition, since the following processing can be implemented by processing by arithmetic unit and software, the start-up, interruption, etc. shall be performed as needed even without special acknowledgment. In addition, the main part of the following processing is performed by the operation control part 22-1, the speed command preparation part 22-2 is used for determination of a speed command, and the abnormality determination part 22-3 is used for abnormality detection.

First, in step 100-1, the state of the passenger conveyor is checked. When the passenger conveyor is in the "stopped" state, the start switch 24 is checked in step 100-2, and the stop is continued if the start switch 24 is not inserted. When the start switch 24 is inserted, the subroutine 110 performs the start process. When the state is "in operation" in step 100-1, the stop switch 25 is confirmed in step 100-3, and if the stop switch 25 is not input, the normal operation processing is performed in the subroutine 120. When the stop switch 24 is inserted, the subroutine 130 performs a stop process. If the state is "abnormal" in step 100-1, since the abnormal stop processing has already been performed as described below, the abnormal stop state is continued until recovery from the abnormality occurs. The process by the main program 100 is periodically repeated.

FIG. 7 is a flowchart showing the processing procedure of the starting process in step 110 in FIG.

This start process is started from the main program 100 when the state of the passenger conveyor is "stopped" and the start switch 24 is inserted. First, in step 110-1, the state of the passenger conveyor is changed to "starting process". Subsequently, in step 110-2, the stop switch 25 is checked. If the stop switch 25 is not inserted, the subroutine 140 performs an abnormal detection process before starting. As a result of the abnormality detection process 140, when there is no abnormality in step 110-3, operation at start-up is performed in step 110-4. The startup operation is to output the speed command for startup to the main motor 15-1 and the control motor 15-2. When it is confirmed in step 110-5 that the startup has been completed normally, in step 110-6 the state of the passenger conveyor is changed to "in operation", and the startup processing is completed. When the stop switch 25 is input irrespective of the start process in step 110-2, when an abnormality is detected in step 110-3, or when the start does not end normally in step 110-5, The process immediately stops starting at step 110-7, turns off the start switch 24 at step 110-8, changes the state of the passenger conveyor to "abnormal" at step 110-9, and at step 110-10. The abnormality notification device 27 is notified of the abnormality. When the state of the passenger conveyor becomes "abnormal", the above confirmation and recovery are performed by the passenger conveyor manager or maintenance inspector by the content.

FIG. 8 is a flowchart showing the processing procedure of the abnormality detection processing of step 140 in FIG.

This abnormality detection process rolls up the emergency stop switch 26-1 in step 140-1, the boarding point and the boarding point plate roll-up detector 26-2 in step 140-2, and the pallet railing accommodating part in step 140-3. When the detector 26-3 is rolled sideways at step 140-4, the detector 26-4 is checked at step 140-5, and the protective guard emergency exit detector 26-5 is checked, If it is determined that "normal" is abnormal in step 140-6, or if any of the steps 140-1 to 140-5 is abnormal, "abnormal" is output in step 140-7. This abnormality detection process includes abnormality detection directly connected to the open / closed state of the protective measure emergency exit 10, and can improve safety.

9 is a flowchart showing the processing procedure of the normal operation processing in step 120 of FIG.

At the time of normal operation, the abnormality detection process of step 140 is performed. Then, if an abnormality is not recognized in step 120-1, the normal speed command is output to the main motor 15-1 as the normal time operation in step 120-2. In addition, in step 120-3, the pallet position is detected using the position detector 19, and in step 120-4, the speed command generator 22-2 calculates the necessary speed for control according to the pallet position. The speed command calculated to the control motor 15-2 is output in step 120-5. If an abnormality is detected in step 120-1, the routine proceeds to a subroutine 130 to perform a stop process.

FIG. 10 is a flowchart showing the processing procedure of the stop processing of step 130 shown in FIG.

This stop processing includes processing for slowly stopping by dropping the speed from the maximum speed at the normal stop and emergency stopping in an emergency. First, in step 130-1, the state of the passenger conveyor is changed to "stopping processing." Subsequently, in step 130-2, it is confirmed whether or not the reason for reaching the stop processing is caused by an abnormality. Operation at stop is to output the speed command for stop to the main motor 15-1 and the control motor 15-2. If it is confirmed in step 130-4 that the stop has been completed normally, the start switch 24 is turned off in step 130-5, the state of the passenger conveyor is changed to "stop" in step 130-6, and the start process is performed. Quit. If an abnormality is detected in step 130-2 or if the stop does not end normally in step 130-4, the processing becomes an abnormal condition, and operation is immediately stopped in step 130-7, and in step 130-8 The start switch 24 is turned off, the state of the passenger conveyor is changed to "abnormal" in step 130-9, and an abnormality is notified to the abnormality notification device 27 in step 130-10. As described above, the abnormal contents are outputted to the abnormality notification device 27, so that even in the case of abnormality, the pursuit and resolution of the cause can be facilitated.

Next, with reference to the side curl detection of step 140-4 of the abnormality detection process shown in FIG. 8, the safety device of the side gap is demonstrated using FIG.

In the same figure, 28 is a clearance shield brush. As shown, when the pallet 1 passes over the high speed conveyor 4 (or the acceleration roller 3, the reduction roller 5), which is the pallet clearance plane driving means, the traveling direction side of the passenger conveyor In the above, the side cover 11 closes the upper side of the pallet 1, but a gap corresponding to at least the height of the pallet necessarily occurs between the high speed conveyor 4 and the side cover 11. Therefore, if the passenger's belongings fall on the pallet clearance surface in the state where this lateral clearance opens, there exists a possibility that the object may fall inside a passenger conveyor from the lateral clearance, and damage the apparatus.

Therefore, in the present embodiment, as the lateral gap shielding means, for example, as shown in the drawing, the gap shielding brush 28 formed by densely displaying fine resin or the like and formed into a brush shape is provided from the side cover 11 by a high-speed conveyor ( 4) The side gap is shielded by hanging on the surface. The gap shielding brush 28 is installed freely before and after the moving direction of the pallet 1 so as not to obstruct the passage of the pallet 1, but the gap shielding brush 28 has resistance to the moving direction side, and the falling object Or part of the passenger's body is prevented from entering the lateral gap.

In addition, when the pushing force to this side is stronger than the resistance of the clearance shield brush 28, the side roll-up detector 26-4 which detects the displacement amount to the side is provided, and an abnormality is detected. When an abnormality is detected by the side curl detector 26-4, the detection result acts as an interrupt process to the above-described abnormality detecting process 140 to emergency stop the passenger conveyor.

In addition, the side gap shielding means is not limited to that shown in Fig. 11, but is configured such that the pallet 1 passes through the pallet 1 with elasticity in an up-down direction using an elastic body to prevent entry of falling objects into the side gap. It is also in accordance with the spirit of the present invention.

As described above, according to the present embodiment, the safety with respect to the side gap can be improved.

Next, details of the pallet 1, which is a main component of the variable speed passenger conveyor, will be described with reference to Figs.

12 is a partial plan view of the pallet, FIG. 13 is a sectional view of the pallet, and FIG. 14 is a partial side view of the pallet.

In these figures, 1-1 is a pallet plate, 1-2 is a comb teeth (parts indicated by solid lines) on the pallet surface, 1-3 is a comb bar (parts shown by diagonal lines) at the end of the pallet, and 1-4 is a pallet plate. Strength member provided on the back side of (1-1), 1-5 is a pallet leg connected between the strength member (1-4) and the wheel shaft, 1-6 is a wheel, 1-7 is a pallet plate (1-1) ) Is the contact surface of the high speed conveyor and roller surface, 29 is the comb surface of the high speed conveyor and roller surface. In addition, in FIG. 12, the part shown to the upper side from the dashed-dotted line saw the surface of the pallet board 1-1, and the part shown to the lower side from the dashed-dotted line saw the lower part of the pallet board 1-1. Indicates. In addition, in FIG.13 and FIG.14, the part shown to the left from the dashed-dotted line saw the side of the pallet board 1-1, and the part shown to the right from the dashed-dotted line is the cross section of the pallet board 1-1. The state seen is shown.

Here, the dimension of the pallet 1-1 is an example, although the space | interval between the pallet railings 7 on either side of a pallet is about 1200 mm, and the length of the progress direction of one sheet of pallet is about 400 mm (1200 mm by three joints), comb teeth. Is about 2mm apart. The shape of the illustrated pallet does not correspond to the above dimensions, but is shown here as a component without being bound by the actual dimensions.

The pallet 1-1 board consists of a metal plate, the surface of the pallet comb 112 is formed, and the pallet railing 7 is fixed to the pallet board 1-1.

The length of the traveling direction of the pallet 1-1 moving integrally also depends on the size of the wheelchair, but, for example, three pallets 1-1 are connected to each other so that the wheelchair can easily ride, and the length is 1000 mm. The above was made.

As described above, according to this embodiment, instead of the large one pallet, the weight increase of the unit pallet of the variable speed passenger conveyor can be suppressed by configuring a plurality of sheets as an integrally connected pallet.

Further, according to the present embodiment, the size of the unit pallet is equal to that of a normal passenger conveyor, and the use of parts and production equipment can be shared, and production costs can be reduced.

In addition, as shown in FIG. 12, the advancing direction edge part of the connection pallet 1-1 is a part which generate | occur | produces a gap according to a speed change, and engages with the pallet before and after contacting, Since it is a part which contacts the pallet clearance surface drive means, the comb teeth 1-3 of a pallet edge part are provided. The comb teeth 1-3 of the pallet ends are configured to move the grooves of the comb teeth 29 of the high speed conveyor and the roller surface, so as to be combined with the comb teeth 1-3 of the pallet ends of other joint pallets. At this time, the comb teeth 1-3 of the pallet end part of the lower part from the pallet board 1-1 enter into the space of the lower part of the comb teeth 1-3 of the different pallet plate end as shown in FIG. Moreover, the comb teeth 1-3 of the pallet end part of the upper part from the pallet board 1-1 act | work with the comb teeth provided in the unloading-plate 6 which formed the same row as the comb teeth 1-3 of the pallet surface, It functions to pick up and drop down the pallet surface.

Thus, according to this embodiment, the safety at the time of pallet coupling can be improved.

In addition, according to the present embodiment, passengers or dropped belongings which have arrived in the pallet gap can be easily returned to the pallet.

Here, the comb teeth 1-3 at the end of the pallet are made of, for example, plastic resin or the like, which is used in a general stepped passenger conveyor, and bolts or the like on the pallet plate 1-1. Is fixed. Therefore, the comb teeth 1-3 at the end of the pallet can be easily different in color from the pallet plate 1-1 made of metal. It can be displayed so that a board | substrate may be enclosed squarely by attaching not only to the advancing direction edge part but also to the lateral end part of a pallet, and not sticking to the boundary part of the pallet in the junction pallet 1-1. This corresponds to the fall prevention means at the time of getting on to the pallet 1-1 at the boarding point.

As described above, according to the present embodiment, it is possible to clarify the distinction between the joint pallet 1-1 which moves as an integral part and the place generating the gap between the joint pallet 1-1 to prevent the fall during the boarding. Can be.

Moreover, as shown in FIG. 13, the height of the comb teeth 1-3 of the pallet edge part is comprised so that it may become higher than the height of the comb teeth 1-2 of the pallet surface, and it falls in the case of boarding the pallet 1-1 and moving. Preventive means. This means that even if a wheel such as a wheelchair, a baby stroller, a trolley or a large suit case on a pallet moves over the comb (1-2) on the pallet surface, the step with the comb (1-3) at the end of the pallet It stops by and can fall to the clearance gap of the pallet 1-1, and can prevent it beforehand.

As described above, according to the present embodiment, there is an effect of preventing passengers or belongings from falling into the gap between the connecting pallets 1-1.

12-14, the strength member 1-4 is provided in the lower part of the pallet board 1-1 as needed. Moreover, the pallet legs 1-5 are provided in the side, and the wheel 1-6 is attached. Each pallet 1-1 in the joint pallet is connected by commonly using the axes of the wheels 1-6 attached to the pallet legs 1-5. Therefore, in the section in which the passenger who moves horizontally, there is no gap inside the connecting pallet, but when the direction is reversed, it is rotatable about the axis of the wheels 1-6 as shown in FIG. Even if the effective length of the joint is more than 1000 mm, the radius at the time of rotation can be restrained to the same length as a single pallet.

As described above, according to the present embodiment, the length in the depth direction of the variable speed passenger conveyor can be suppressed.

In addition, as shown in FIG. 12, since the joint pallet has a long length, when passing through the acceleration roller 3 and the reduction roller 5, the roller speed differs significantly before and after. Therefore, when the acceleration roller 3 and the reduction roller 5 drive the pallet by the frictional force, when the entire pallet 1-1 is in contact with the roller, unnecessary force by the speed difference is applied in the advancing direction. . Therefore, the contact surface 1-7 which defines the contact position with a roller is attached to the lower part of a pallet. As shown in FIG. 13, since the pallet 1-1 and the conveyor and the roller contact only at the contact surfaces 1-7, and the other parts are brought into non-contact by the height of the pallet legs 1-5, the driving force is the contact surface ( Only available in 1-7). The area of the contact surface (1-7) is based on the diameter of the contacting roller and the degree of change of the speed of the roller, so that the unnecessary force received from the speed difference of the roller drives the pallet within the range of the strength of the connection part of the joint pallet. It is set to get enough power to do so.

As described above, according to the present embodiment, it is possible to facilitate the manufacture, construction, installation and maintenance of the variable speed passenger conveyor.

Next, another embodiment of the pallet drive means of the variable speed passenger conveyor will be described with reference to Figs.

It is a side view of the pallet drive means which drives an acceleration / deceleration of a pallet.

In the same figure, 16-3 is a control drive shaft which is driven by the control motor 15-2 to transmit the driving force to the control belt 31, 16-4 is driven by the main motor 15-1 for acceleration Acceleration belt drive shaft for transmitting the driving force to the belt 30, 17-5 is the acceleration belt drive chain, 17-6 is the control belt drive chain, 30 is the acceleration belt, 31 is the control belt, 32 is the acceleration belt ( 30) and a belt moving plate provided in the gap between the high speed belt (4). In addition, in the same figure, the code | symbol part same as the code | symbol shown in FIG. 3 represents the same part.

This pallet drive means replaces the acceleration roller 3 and the reduction roller 5 in the previous embodiment with a plurality of belts whose sequential speeds change. Here, the acceleration roller 3 is the acceleration belt 30, the control roller 14 is the control belt 31, and the acceleration roller drive shaft 16-2 is the acceleration belt drive shaft 16-4. Thus, the acceleration roller drive chain 17-2 is replaced with the acceleration belt drive chain 17-5, and the control roller drive chain 17-3 is replaced with the control belt drive chain 17-6. In addition, the operation of each component is replaced by the operation of the above-described component, the control method and the like can be applied as described above.

In addition, when the diameter of the roller which drives a belt is large, the moving member like the belt moving plate 32 may be provided in the belt and the belt, the moving part of a belt, and a high speed conveyor.

Figure 16 is a side view of the pallet drive means for driving the pallet by high speed chain coupling at high speed. In the same figure, 1-8 is a chain engaging part provided in the lower part of the pallet 1, 33 is a high speed body, 34 is a high speed body gear.

In the variable speed passenger conveyor, the high speed section, which occupies most of its length, moves the pallet 1 at a constant speed while maintaining a constant pallet clearance. Therefore, as shown, the high-speed chain 33 that rotates at the highest speed of the passenger conveyor is installed in the high-speed section. Moreover, the high speed chain gear 34 which rotates simultaneously is provided in the common high speed conveyor drive shaft 16-1, and the high speed chain 33 is driven.

When the pallet 1 is driven in the acceleration section by the pallet accelerating means and passes through the gear 34 for the high speed chain, the high speed chain 33 and the chain coupling part 1 using the curvature of the gear 34 for the high speed chain. -8) Accordingly, the pallet 1 is driven by the high speed chain 33 in the high speed section. At the end of the high speed section, the engagement of the high speed chain 33 and the chain engaging portion 1-8 is released by the curvature of the high speed body quoting gear 34 in the opposite operation, and the driving of the pallet 1 Take over to the pallet deceleration means.

In addition, although not shown in particular, even in the part which the pallet reverses direction or returns to the boarding point part, it is clear that the drive by chain coupling can be similarly applied if the speed change is not needed in the area | region.

Here, when synchronizing the speeds of the pallets and the pallet gap surfaces, the main speeds may be the same, for example, the diameters of the drive rollers of the high speed conveyor 4 and the high speed chain gear 34 are the same. On the contrary, it is also possible to set the speed of a pallet and a pallet clearance surface separately by interposing a gear in a drive shaft or changing the diameter of the gear 34 for high speed chains.

As described above, according to the present embodiment, by separating the pallet driving means and the pallet gap surface driving means in the high speed section, the speeds of the pallet and the pallet gap surface can be set independently.

17 is a side view of a pallet drive means using a linear motor in the acceleration / deceleration section and a chain in the high speed section.

In the same figure, 23 is a voltage-frequency control part, 35 is a linear motor control apparatus, and 36 is a primary coil of a linear motor. In addition, in the same figure, the code | symbol part same as the code | symbol shown in FIG. 16 represents the same part.

As illustrated, the plurality of primary coils 36 that can be displayed in the acceleration section and the deceleration section (not shown) are provided from the linear motor control device 35 to the pallet 1 through the voltage / frequency control unit 23. The voltage and / or frequency are supplied such that the speed is a value according to the position. As a result, pallet acceleration means and pallet reduction means are configured.

18 is a cross-sectional view of the pallet driving means shown in FIG. 17.

In the same figure, 37 is a secondary conductor of a linear motor. In addition, in the same figure, the part of code | symbol same as the code | symbol shown in FIG. 13, FIG. 17 shows the same part.

As shown, since the high-speed conveyor or roller which is a pallet clearance surface drive means is arrange | positioned under the space | interval of the pallet railing 7 of the pallet 1, the primary side coil of the linear motor which is a pallet acceleration means and a pallet deceleration means. 36 is disposed on the side thereof. A secondary conductor 37 is attached to the pallet 1 at a position opposite to the primary side coil 36. Further, the high speed chain 33 and the chain engaging portions 1-8, which are pallet high speed driving means, are also attached to the lower side of the pallet.

It goes without saying that it is also possible to drive the pallet by an all-round linear motor without using the high speed chain 33.

According to this embodiment, by separating the pallet driving means and the pallet gap surface driving means between all the sections, the speeds of the pallet and the pallet gap surface can be set independently.

According to the embodiment, the linear motor is arranged only in the acceleration / deceleration section and the high-speed section is chain driven, thereby reducing the cost of equipment and construction.

Here, the relationship between pallet speed and pallet gap surface speed is demonstrated using FIG.

FIG. 19A corresponds to the pallet drive means described in the embodiments of FIGS. 1 to 14 and is a synchronous type in which the pallet speed and the pallet gap surface speed coincide.

In the case of the synchronous type, since there is no difference between the pallet speed and the pallet gap surface speed, there is no problem even if it falls from the pallet to the pallet gap surface, and the pallet gap surface driving means is a safety device against falling. For falling to the pallet gap surface, the synchronous type without speed difference is the most stable method. However, the absence of a speed difference between the pallet speed and the pallet gap surface speed in the high speed section is transported even if the passenger is on the pallet and also on the pallet gap surface, so that it is easy to walk on the pallet and the pallet gap surface. However, in the variable speed passenger conveyor, the pallet gap surface at the intermediate portion generated by acceleration is a temporary area and disappears by deceleration of the discharging end. If the pallet gap surface is filled by the passenger walking, there is a risk that the passenger's standing space will disappear when the pallet gap surface disappears at the discharging end, and it will fall down at once.

Therefore, in order to avoid such a situation, the ratio of the speed of the pallet speed shown in FIG. 19B and the pallet gap surface speed is constant, and the pallet speed and pallet gap surface speed shown in FIG. 19C There is an isoscelesoidal type with a difference in speed between the two.

If the pallet and the pallet gap surface are moved as shown in Fig. 19B or 19C, the pallet speed is faster, and the passengers on the pallet are in a state in which the pole surface between the pallets moves in the reverse direction by the speed difference. As a result, walking the pallet gap surface is at an interval equal to that of walking a normal passenger conveyor in a reverse direction, and psychologically, the effect is less than that of a normal walking, resulting in a state that is difficult to walk physically. .

Furthermore, in a state where there is a speed difference between the pallet speed and the pallet clearance surface speed, even if a wheel such as a wheelchair, a baby stroller, a handcart or a large chute case loaded onto the pallet falls on the pallet clearance surface due to an error in maintenance operation. It is easy to return by the speed difference and to return on a pallet.

In addition, the speed difference of a pallet speed and a pallet clearance surface speed shall be below the magnitude | size of the initial velocity of the pallet in a boarding point part here. This is because safety is maintained by making the influence of the speed difference in the intermediate portion equal to the speed difference of the boarding point portion.

As such, according to the present embodiment, the passenger's walking on the passenger conveyor can be reduced psychologically and physically.

In addition, according to the present embodiment, there is an effect of returning a passenger or dropped belongings to the pallet gap to the pallet.

When the pallet driving means and the pallet gap surface driving means are provided independently, the speed difference between the pallet speed and the pallet gap surface speed can be physically set to increase the speed of the pallet gap surface. However, this setting assists the above-mentioned walking and promotes walking, thereby increasing the risk at the getting off inlet, and is not practically usable.

20 is a cross-sectional view showing an example of drive means for generating a speed difference between pallet acceleration means / pallet deceleration means and pallet clearance surface drive means in the corresponding portion by friction driving by a roller.

In the same figure, 38 is a roller for driving a pallet, 39 is a roller for driving a clearance gap surface. In addition, in the same figure, the code | symbol part same as the code | symbol shown in FIG. 4 represents the same part.

As shown, in the present embodiment, the rollers used for the acceleration roller 3 and the reduction roller 5 are used for the pallet driving roller 38 having two different diameters and the pallet gap surface driving roller ( 39). The pallet 1 prepares the contact surface 1-7 in the position which opposes the pallet drive roller 38, and makes the other part non-contact with the pallet clearance surface drive roller 39. As shown in FIG. The pallet gap surface is constituted by a roller 39 for pallet gap surface driving. The pallet driving roller 38 and the pallet gap surface driving roller 39 are driven by the same drive shaft. As a result, since the rotation speed of the pallet drive roller 38 and the pallet clearance surface drive roller 39 becomes the same, the main speed of a roller becomes a ratio of the diameter of each roller. Thus, for example, when the diameter of the pallet driving roller 38 is 80 mm and the diameter of the pallet gap surface roller 39 is 60 mm, the pallet speed and the pallet gap surface speed are at different speeds at a ratio of 4: 3. It is feasible.

As described above, according to the present embodiment, since the speed difference can be realized by using both the pallet driving means and the pallet gap surface driving means, the number of parts can be reduced and the configuration can be simplified.

In one embodiment of the present embodiment, the floor surface is constituted by a conveyor using a belt and a plurality of rollers whose speeds change sequentially.

In addition, the floor surface is characterized by consisting of a plurality of belts with a sequential speed change.

Moreover, the difference between the speed of the floor surface and the speed of the said pallet is in the range smaller than the speed of the pallet in a boarding point part.

In addition, the floor surface is composed of a conveyor using a belt and a plurality of rollers in which the speed is sequentially changed, and the speed at each point of the roller is characterized in that the speed of the pallet at each point is reduced by a certain ratio. .
