As described above, the conventional conveyor apparatus employs a form in which power is transmitted to the endless pallet 1 by circulating the conveying chain 23 in a vertical plane perpendicular to the plane of the endless conveying path. As a result, the height of the entire apparatus is increased, so that the underlay floor La (FIG. 27) for installing the drive apparatus is increased, and the construction cost cannot be avoided.

In addition, since the weight of the structure under the floor increases, the strength of the peripheral equipment also needs to be set high. Even if the transport path is on a moving sidewalk set on a horizontal plane, it is difficult to install a driving device for the same. It required underfloor work and could not be installed on the existing floor.

A technical object of the present invention is to reduce the height of the entire apparatus and to make it possible to install the apparatus on an existing floor in a moving sidewalk.

2 can transmit the driving force to the endless pallet 30 if one or more can always be engaged with the chain 105.
It is not necessary to attach to all pallets.

Also in this case, the chains 105, 105 disposed on the left and right sides of the endless pallet 30 are independently driven by the dedicated motors 106, 106, respectively. Are synchronized by a control device (not shown) based on the output of the control unit.

The sprockets 103 are mechanically synchronized with each other.

More specifically, the lower ends of the rotating shafts 121, 121 of the twin sprockets 103, 103 are formed on bevel gears (or helical bevel gears) 122, 122. Gears 122, 122
Bevel gear (or helical bevel gear) 1 that can mesh with
They are connected by a rod 124 having 23 and 123. Therefore, when one twin sprocket 103 is driven by the motor 106, the power is changed from the bevel gear 122 of the one rotating shaft 121 to the one bevel gear 123 of the rod 124,
Rod 124, the other bevel gear 123 of rod 124,
The power is transmitted to the bevel gear 123 of the other rotating shaft 121, and the other twin sprocket 103 rotates in synchronization with the one twin sprocket 103.

In the drawings, the same parts as those of the above-described seventh embodiment are denoted by the same reference numerals.

The conveyor device according to the ninth embodiment also applies the present invention to a moving sidewalk. The conveyor device of the ninth embodiment employs a chain driving method as the conveying means 130 for conveying the endless pallet 30 in the same manner as the above-described seventh embodiment, and eccentrically guides the guide rails. It is intended to facilitate the assembly and maintenance of the pallet, to reduce the radius of rotation in the spiral circuit, and to shorten the total extension distance of the guide rail, and to engage with the central rollers 104, 104 of each chain 105, 105.

Therefore, when the side rollers 111 and 112 of the chain 105 are wound around the upper and lower sprockets 107 and 108, the center roller 104 of the chain 105 can engage with the pallet-side recess 131, and the chain 105 is driven by the motor 106. By doing so, power can be transmitted directly from the chain 105 to the pallet, and the endless pallet 30 can be propelled. In this case, the twin sprocket 103 is used to transmit power smoothly.
And a triple roller type chain 105, and a chain 10
5 is described by way of example in which the center roller 104 is engaged with the pallet-side concave portion 131. However, the present invention is not limited to this. For example, a normal sprocket and a single roller type chain may be used. Providing projections at predetermined intervals on the link of the single-roller type chain, or providing protrusions to the side of the link of the single-roller type chain at predetermined intervals, and attaching the projections to this extension, These projections may be engaged with the pallet-side recess 131.

As described above, the conveyor device of the ninth embodiment includes the chain 105 arranged on the side of the endless pallet 30 in the recess 131 formed by recessing the side edge of the endless pallet 30 from the side end surface. The endless pallet 30 is driven by directly engaging the center roller 104 of FIG. For this reason, a plate piece for transmitting power is not required, the number of parts can be reduced, and the cost of the apparatus can be reduced accordingly. Furthermore, when each pallet is bent, there is no interference member with the adjacent pallet, so that the amount of rotation between the connecting rods 32 (see FIG. 1) in the horizontal plane can be increased in the turning direction, and the forward and backward paths of the endless transport path can be reduced. The radius of gyration of the circuit to be connected can be reduced, so that the forward path and the return path can be arranged close to each other.

I have. Note that the plate member 142 does not necessarily need to be set to have a length that extends over the entire length of the pallet in the pallet traveling direction, and need not be attached to all pallets. In short, if one or more chains can be always engaged with the chain described later, the driving force can be transmitted to the endless pallet 30 side.

On the other hand, on the left and right sides of the endless pallet of the endless transfer path, twin sprockets 14 whose rotation axes are set to be perpendicular to the pallet transfer direction from the side.
3 and 143 are arranged one by one in the pallet conveyance direction, and the concave portions 14 between the left and right sprockets 144 and 145 are arranged.

The conveyor device of the eleventh embodiment also applies the present invention to a moving sidewalk. The conveyor device of the eleventh embodiment employs a linear motor using an inverter as a power supply circuit as a transporting means 160 for transporting the endless pallet 30, and based on a speed difference between a set speed and an actual speed, a power source of the power source is controlled. The frequency is variably controlled and supplied to a linear motor.

That is, the linear motor is a traveling element 161 composed of a conductive plate (here, a metal plate) serving as a secondary-side conductor, which is attached to the lower surface of both side edges of the endless pallet 30 at predetermined intervals. , 161 and

It is arranged so that power is transmitted to the endless pallet 30 in a non-contact manner and driven. For this reason, no mechanical friction or twisting occurs between the components of the drive device, and it is not always necessary to synchronize the left and right linear motors of the endless pallet, and rough setting is possible. Even when synchronizing, it can be easily set by the power supply device.

As described above, since the endless pallet 30 is formed by connecting a large number of pallets 31a to 31c..., There is a large play as a whole. For this reason, in addition to the synchronization between the linear motors on both sides of the endless pallet, when trying to synchronize between the linear motors installed on the outward path and the return path on both sides of the circuit, the behavior of the pallet caused by the backlash causes , A slip occurs between the stator 162 and the runner 161. Therefore, a speed detector that detects the actual moving speed of the endless pallet is installed on one side of the winding circuit, and the linear motor on the side where this speed detector is installed is synchronized with the actual moving speed of the endless pallet. To take. As a result, there is no driving device or the like below the endless pallet 30, so that the height of the entire device can be suppressed, and the size of the digging allowance under the floor can be significantly reduced. Moreover,

The stators 172 and 173 are arranged at upper and lower positions in the endless transport path that can face the runner 171 so that the motive power is transmitted to the endless pallet 30 in a non-contact manner and driven. Accordingly, also here, no mechanical friction or twisting occurs between the components of the drive device, and it is not necessary to always synchronize between the left and right linear motors of the endless pallet, and rough setting is possible. Even when synchronizing, it can be easily set by the power supply device.

Also, in this case, in addition to the synchronization between the linear motors on both sides of the endless pallet, if synchronization is attempted between the linear motors installed on the outward path and the return path on both sides of the spiral circuit, the large play of the endless pallet will occur. Of the pallet, the slippage occurs between the stators 172 and 173 and the traveling element 171. Therefore,
A speed detector that detects the actual moving speed of the endless pallet is installed on one side of the circuit, and the linear motor on the side where this speed detector is installed is synchronized with the actual moving speed of the endless pallet. Like that. This allows
There is no drive device or the like below the endless pallet 30, so that the height of the entire device can be suppressed, and the size of the digging allowance under the floor can be greatly reduced. In addition, no noise or vibration is generated from the drive unit, and it is not necessary to consider the wear of the drive unit, so that the life of the device can be extended and the installation space can be made compact. as a result,
When the conveyor device is a moving sidewalk as in the twelfth embodiment, it can be installed on an existing floor, and construction costs can be significantly reduced. Furthermore, the weight of the entire device can be reduced, and the strength of peripheral equipment can be set low.
The degree of freedom in design expands.

Here, the traveling element 17 of the linear motor is also used here.
Although an example using a metal plate (secondary conductor) as the stator 1 and a primary winding as the stator 172 has been described as an example, the invention is not limited to this. And a plurality of coils corresponding to the permanent magnets may be installed in parallel as a stator.

In each of the above-described embodiments, the present invention has been described by taking, as an example, one in which the present invention is applied to a moving sidewalk having a flat path.

Rollers and screws on the flat path in the endless transport path,
Pinions, chains, stators of linear motors, etc. are arranged. Even in such a case, the size under the endless pallet can be significantly reduced as compared with the conventional case, similarly to the above-described embodiments.

In each of the above-described embodiments, a drive device is provided on both sides of the endless pallet 30 as an example. However, as described above, the endless pallet 30 is connected to each other by connecting rods. And the connecting rod is always moved on the endless conveyance path with its both end positions defined by the guide rollers, whereby the free rotation of each pallet is also regulated. The endless pallet 30 can be propelled without any trouble even if the driving device is installed on only one side of the pallet 30.
