Description

  The present invention relates to an automatically driven roller conveyor that is used by being embedded in a floor surface of a cargo room such as a cargo vehicle or a warehouse.

Carrying loads or cargoes inside and outside cargo compartments such as freight vehicles and warehouses was a labor-intensive task for workers.
In order to solve this problem, a roller conveyor having an elevating function has been proposed. For example, a roller conveyor (hereinafter referred to as “conventional example 1”) described in Japanese Patent Application Laid-Open No. 2000-44025 is stored and installed in each floor of a cargo compartment or warehouse, and is used as a base when loading (loading) a cargo. Using roller guide means having a guide roller that moves up and down on the frame, the roller frame is raised so that the load receiving roller protrudes from the floor surface, and the load is transferred through the load receiving roller and sequentially stacked. After loading, the load receiving roller is lowered below the floor surface and stored in the floor surface to land the loaded luggage on the floor surface.
A lift-up type roller conveyor (hereinafter referred to as “conventional example 2”) described in Japanese Patent Application Laid-Open No. 11-227915 is disposed in a channel embedded in a cargo bed, and has a number of rollers as a lifting mechanism. A airtight cylindrical body (lifting means) disposed between the lower surface of the roller tray and the bottom plate of the channel, a compressed air source for supplying compressed air to the airtight cylindrical body, and the compressed air A control box connected to the source is provided. When the control box is operated and compressed air is fed into the airtight cylindrical body, the airtight cylindrical body expands and the roller tray rises, and the rollers of the roller tray protrude from the upper surface of the loading platform, When the compressed air in the airtight cylindrical body is discharged to the outside, the airtight cylindrical body becomes flat and the roller is positioned below the loading platform.
In both the conventional example 1 and the conventional example 2, the load receiving roller of the roller conveyor that has moved up on the floor surface and the transfer of the load on the roller are manual push operations by the workers, and therefore rationalization of the operation has been a problem.
In order to solve this problem, a moving floor apparatus (hereinafter referred to as “conventional example 3”) described in JP-A-10-175714 has been proposed. This moving floor device has an automatic endless slat conveyor lined with flat bars. One end of the slat conveyor is wound around the drive wheel and the other end is driven around the driven wheel. It is a drive type.

JP-A-10-175714 Japanese Patent Laid-Open No. 11-227915 JP 2000-44025 A

In Conventional Example 3, the entire floor of the luggage compartment rotates endlessly, in other words, the construction of automating the transfer of the luggage in the luggage compartment, so that it is necessary to closely load the preloaded luggage and the later loaded luggage. Therefore, it is necessary for the worker to load always to watch the loading situation, and there is a problem that burdens the operator. In addition, in the case of a failure, there is a disadvantage that a forklift or the like cannot be put in the luggage room in order to unload the load, and a smooth failure cannot be handled smoothly.
An object of the present invention is to reduce the burden on an operator who carries in a package and to facilitate the handling of a failure or the like.

The present invention includes a roller conveyor body embedded in a floor surface of a cargo compartment, and a driving device that applies a driving force to the roller conveyor body via a drive transmission means. The roller conveyor body is provided with a conveyor section and a lifting operation means for moving up and down the conveyor section. The conveyor section is provided in an outer roller support frame to which a plurality of drive rollers arranged at intervals in the length direction are rotatably attached, and the outer roller support frame. An inner roller support frame on which a plurality of non-driving rollers arranged at intervals are rotatably mounted, an outer roller traveling frame on which the driving roller can travel, and an outer roller traveling frame. And an inner roller traveling frame on which the non-driving roller can travel. The outer roller support frame is provided with an opening for the driving roller and an opening for the non-driving roller at positions facing the driving roller and the non-driving roller, respectively. Each driving roller has an upper end protruding from the opening for the driving roller, and each non-driving roller has an upper end protruding (exposed) from the opening for the non-driving roller. The outer roller running frame is formed with a driving guide for the driving roller for raising and lowering the outer roller support frame, and the inner roller running frame is provided with the non-rolling guide for raising and lowering the inner roller support frame. A travel guide for the drive roller is formed. The driving roller is for carrying the loaded luggage, and the non-driving roller is an idle roller that receives the load of the loaded luggage. The elevating / lowering operating means includes an elevating / lowering operating part, an action transmitting part and a joint member for reciprocating the outer roller support frame. The drive transmission means includes an output side drive transmission unit that receives a drive force from the drive device, and an input side drive transmission unit that receives a drive transmission force from the output side drive transmission unit. The output side drive transmission unit includes an output side drive transmission wheel. The input-side drive transmission unit is arranged corresponding to each of the drive rollers, and is connected to the output-side drive transmission vehicle and the input-side drive transmission vehicle, the drive transmission vehicle, and the drive transmission vehicle that are linked to each other by the linkage transmission means. A driven transmission wheel is provided that is linked and the driven shaft at the center of rotation is constituted by the roller pin end portion of the drive roller, and the input side drive transmission wheel and the drive transmission wheel are linked.
In the present invention, in order to reduce the weight of the roller conveyor body, increase the efficiency of conveyance, and the like, it is preferable that the driving roller and the non-driving roller have different widths so that the driving roller is wider than the non-driving roller. .
In the present invention, in order to prevent lateral displacement of the loaded luggage and to provide straightness, it is preferable to form a groove on the outer peripheral surface of the drive roller in a direction perpendicular to the carrying direction of the loaded luggage.
In the present invention, a roller chain, a timing belt or the like is used as the interlocking transmission means. In this roller chain, it is hung around the output side drive transmission wheel and the input side drive transmission wheel.
In the present invention, in order to increase the strength of the conveyor portion, both the outer roller support frame and the inner roller support frame are both groove-shaped members, and the upper plate portion of the outer roller support frame is placed on the upper roller support frame. The plate portions are joined in a superposed state, and the bottom plate portion of the inner roller running frame is placed on the bottom plate portion of the outer roller running frame using both grooved members as the outer roller running frame and the inner roller running frame. Bonding in a polymerized state is good. In this case, a plurality of openings from which the upper end of the non-driving roller can protrude are formed in the upper plate portion of the inner roller support frame, and these openings are openings for the non-drive roller of the outer roller support frame. And placed in an opposing positional relationship.
In this invention, in order to enhance the versatility of the roller conveyor body and suppress the failure, it is preferable that the interlocking relationship between the drive transmission vehicle and the driven transmission vehicle in the input side drive transmission unit can be interrupted by the continuous means. .
In this invention, in order to be able to oppose the change in the dimension of the cargo room in the depth direction, it is preferable to divide the conveyor section. For example, the conveyor section is an activation conveyor section, and a standard conveyor connected to the activation conveyor section. And an adjustment conveyor unit connected to the standard conveyor unit.

According to this invention, since the roller conveyor body embedded in the floor of the cargo compartment is formed with a low seat height by combining the lifting function and the automatic cargo transport function, the seat height space of the cargo compartment is reduced. In addition, the overall weight of the conveyor body itself can be significantly reduced, and the weight of the loaded luggage can be reduced.
According to the present invention, the low seating structure of the roller conveyor main body facilitates the embedment installation on the floor surface of the cargo compartment, and the effect of reducing the installation cost is great.
According to this invention, since the idling roller that is a non-driving roller that exclusively receives the load of the loaded load and the drive roller for loaded load conveyance are combined, the loaded load can be automatically conveyed more smoothly, The burden on the operator can be reduced, and the response due to failure can be performed smoothly.

The holding portion 33 shown in FIG. 16 is connected to both connecting plates 34 a of the lift-up joint 34 via the movable portion 33 a and the lift-up operating pin 35, and both connecting plates are connected to the inner roller support frame via the holding pins 36. 12 support plate portions 12b.
For this reason, the operating screw shaft 32 is rotated by the rotation operation of the socket 31a of the elevating / lowering operation unit 31, and thus the movable unit 33a of the holding unit 33 is moved in the left-right direction in FIG. The support frame 12 is pulled in the same direction as the movable portion, and the idling roller 14 travels on the travel guide portion 16c of the inner roller travel frame 16 through the wheel portion 14a. Since the outer roller support frame 11 that is integral with the inner roller traveling frame is also pulled in the same direction as the inner roller traveling frame, the driving roller 13 travels along the traveling guide portion 15c through the wheel portion 13a. As a result, both the inner and outer roller support frames move in parallel while moving up and down as a result of the rotation of the drive roller 13 and the idling roller 14.

This is the same as the connection method between the ends.

Moreover, the adjustment conveyor part C5 is demonstrated with reference to FIGS. 1-3, FIG.27, and FIG.28.
The adjustment conveyor unit C5 shown in the drawing has the same basic configuration and operation as the standard conveyor unit C2, and therefore, detailed description of the common configuration and operation will be omitted and only the characteristic configuration will be described.
Moreover, the code | symbol used for description of the standard conveyor part is used as it is about the code | symbol which shows the structural part of the standard conveyor part C2 corresponding to the structural part of the adjustment conveyor part C5.
Hereinafter, the component part of the adjustment conveyor part C5 different from the standard conveyor part C2 is demonstrated.
The adjustment conveyor C5 is used when the distance between the standard conveyor C4 located on the innermost side of the cargo compartment F and the side wall surface does not satisfy the length of the standard conveyor C2.

Universal joints 51 a and 51 b are attached to both ends of the rotational drive transmission shaft 51. One universal joint 51a is detachably connected to the socket 44, and the other universal joint 51b is detachably connected to the socket 53a of the rotary drive main transmission shaft 52.
4 and 29, as shown in FIG. 4, the rotary drive main transmission shaft 52 has the outer roller support frame 11 and the storage chamber 70 in the width direction in the proximal end portion (lower end portion in the drawing) of the starting conveyor portion C1. It arrange | positions so that it may cross in the figure (left-right direction). The rotation drive main transmission shaft 52 is rotatably supported by the support plate portion 11b of the outer roller support frame 11, and both end sides thereof protrude outward from the side plate portion Rb of the embedded frame R. Sockets 53 a and 53 b are attached to both ends of the rotary drive main transmission shaft 52. Further, a sprocket 54 that is an output side drive transmission wheel is attached to the left end side of the rotary drive main transmission shaft 52 in FIG. 4, and this sprocket is located in the storage chamber 70, and a sprocket 79 of the input side drive transmission unit 7. It is arranged on a straight line.

The storage chamber 70 for storing the input side drive transmission unit 7 is formed in a reverse groove shape or a cylindrical shape, and in the example shown in FIGS. 6 and 7, it is formed in a cylindrical shape, and its upper surface is outside the conveyor portions C1 to C4. The same surface as the upper surface of the upper plate portion 11a of the roller support frame 11 is formed. The storage chamber 70 is disposed adjacent to one side (left side) of the conveyor parts C1 to C4 as shown in FIGS. 2 and 4, and the length of the conveyor parts C1 to C4 to which the length is connected. It is set to the same length. The storage chamber 70 is connected to each outer roller support frame at a position of the side surface of the outer roller support frame 11 in each of the conveyor portions C1 to C4 (not shown).
Are integrally connected. For this reason, the storage chamber 70 can move in parallel with the outer roller support frames 11 while moving up and down.
In the storage chamber 70, the input-side drive transmission unit 7 is disposed in a facing positional relationship with each drive roller 13 (FIG. 30).

Since each input side drive transmission unit 7 is unitized and has the same configuration, the input side drive transmission unit in the start-up conveyor unit C1 shown in FIG. 4 will be mainly described with reference to FIGS. 4, 21, 27, and 30. Description will be made with reference to FIG. 36 and other input side drive transmission units will be described as necessary, but detailed description thereof will be omitted.
The input-side drive transmission unit 7 includes a gear box 71 as shown in FIGS. 30 to 33, and the gear box is disposed in the storage chamber 70 corresponding to each drive roller 13. The gear box 71 can be moved in the storage chamber 70 by a disconnecting means 8 described later. As shown in FIGS. 4, 31, and 32, the rotation input shaft 73 and the driven shaft 17 a that is the end of the roller pin 17 of the drive roller 13 are arranged in each gear box 71 side by side.
The rotation input shaft 73 and the driven shaft 17a are rotatably supported through bearing holes 71a and 71b on both side plates of the gear box 71. As shown in FIG. 32, the one bearing hole 71b is a long and long hole, and the driven shaft 17a penetrates the bearing hole so as to be relatively movable. A drive transmission wheel 74 and a driven transmission wheel 75 are attached to the rotation input shaft 73 and the driven shaft 17a, respectively, and the two transmission wheels are arranged to face each other.
Between the drive transmission wheel 74 and the driven transmission wheel 75, first and second intermediate transmission wheels 76 and 77 are provided. The rotation shafts 76a and 77a, which are the rotation centers of the first intermediate transmission wheel 76 and the second intermediate transmission wheel 77, pass through the long hole-shaped guide holes 71c and 71d opened in the both side plates of the gear box 71. Yes. The guide holes 71 c and 71 d are formed in an arc shape as shown in FIG. 36 and are located on a circular locus concentric with the rotation input shaft 73. Since the rotation shafts 76a and 77a are movable in the guide holes 71c and 71d, the first and second intermediate transmission wheels 76 and 77 are free gears.
The first and second rotating shafts 76a and 77a are provided with the spring force of the first and second pressing springs 78a and 78b shown in FIGS. In the example shown in FIG. 36, the first intermediate transmission wheel 76 is applied with a spring force upward by a first pressing spring 78a on the rotating shaft 76a. The second intermediate transmission wheel 77 has a rotating shaft 77a applied with a spring force downward in the figure by the second pressing spring 78b.

Here, the meshing relationship in the drive transmission wheel 74, the driven transmission wheel 75, and the first and second intermediate transmission wheels 76 and 77 will be described.
As shown in FIGS. 32 and 36A, when the drive transmission wheel 74 rotates counterclockwise (rotation in the direction of the arrow in FIG. 32) through the rotation input shaft 73, the first intermediate transmission wheel 76 rotates to the right. Is moved downward in the bearing hole 71 a against the spring force of the first pressing spring 78 a and meshed with the driven transmission wheel 75. On the other hand, since the second intermediate transmission wheel 77 rotates to the right, the rotation shaft 77a is moved downward in the bearing hole 71b and the meshing with the driven transmission wheel 75 is released. At this time, the disengagement state is maintained by the downward spring action of the second pressing spring 78b.
As a result, the rotational force of the drive transmission wheel 74 is transmitted to the driven transmission wheel 75 via the first intermediate transmission wheel 76 and further transmitted to the drive roller 13 through the driven shaft 17a, so that the drive roller rotates to the right.
As shown in FIGS. 34 and 36 (a), when the drive transmission wheel 74 rotates clockwise (rotation in the direction of the arrow in FIG. 34) through the rotation input shaft 73, the first intermediate transmission wheel 76 rotates counterclockwise. Is moved upward in the bearing hole 71a by the spring force of the first pressing spring 78a, away from the driven transmission wheel 75, and the engagement is released. On the other hand, since the second intermediate transmission wheel 77 rotates counterclockwise, the rotation shaft 77a is moved upward in the bearing hole 71b against the spring force of the second pressing spring 78b and meshes with the driven transmission wheel 75. At this time, the meshing state is maintained by the action of the spring above the second pressing spring 78b.
As a result, the rotational force of the drive transmission wheel 74 is transmitted to the driven transmission wheel 75 via the second intermediate transmission wheel 77 and further transmitted to the drive roller 13 through the driven shaft 17a, and the drive roller rotates counterclockwise.

The input side drive transmission unit 7 is provided with a disconnecting means 8 for temporarily disconnecting the interlocking relationship between the driven transmission wheel 75 and the drive transmission wheel 74 that are directly connected to the drive roller 13.
The disconnecting means 8 will be described with reference to FIGS.
Each gear box 71 is sandwiched and held between upper and lower groove-shaped holding frames 81 and 82. As shown in FIG. 30, the holding frames 81 and 82 have a length extending from the start conveyor part C <b> 1 to the adjustment conveyor part C <b> 5, and both ends are fixed by connecting members 83 and 84. A reinforcing member 85 that also serves as a spacer is disposed between the holding frames 81 and 82 at an appropriate interval, and these also contribute to fixing the gear box 71 located between the upper and lower holding frames. The gear box 71, the holding frames 81 and 82, the connecting members 83 and 84, and the reinforcing member 85 are placed in the storage chamber 70 in an integrated state. In addition, a shaft mounting base 86 is disposed on the outer side of one of the connecting members 83 (right side in FIG. 30). The shaft mounting base 86 is fixed to the side plate of the storage chamber 70 with bolts or the like. A feed screw shaft 87 is horizontally passed from the shaft mounting base 86 toward the connecting member 83 opposed to the shaft mounting base 86. One end portion of the feed screw shaft 87 is screwed into a screw portion (not shown) attached to the connecting member 83, and the other end portion penetrates the shaft mounting base 86 and protrudes to the outside (right side in FIG. 30). ing. A rotation operation unit 88 is attached to the protruding end.
By rotating the rotation operation portion 88, the feed screw shaft 87 rotates, and the connecting member 83 can move to the left and right in FIG. 30 along with this rotation. Therefore, the holding member 81 is held via the holding frames 81 and 82. The gear box 71 provided integrally with the frame can move in the storage chamber 70 along its length direction.
For example, if the gear box 71 is moved to the right by a predetermined distance from the position of the solid line to the position of the chain line in FIG. 32, the rotation input shaft 73 and the first and second intermediate transmission wheels 76 and 77 are attached to the gear box. Move to the right by the same distance as the gearbox. Along with this movement, the first and second intermediate transmission wheels 76 and 77 are separated from the driven transmission wheel 75 as shown in FIGS. Since the rotational force from the drive transmission wheel 74 is not transmitted to the driven transmission wheel 75 in this state, the drive roller 13 can idle as in the driven transmission wheel. This idling state corresponds to a so-called neutral state because the interlocking relationship between the drive transmission wheel 74 and the driven transmission wheel 75 in the input side drive transmission unit 7 is solved.
The disconnection means 8 can enable the drive transmission wheel 74 and the driven transmission wheel 75 to be linked or blocked by moving the gear box 71.

As shown in FIGS. 4, 7, and 33, the distal end side of the rotation input shaft 73 of the drive transmission wheel 74 in each input side drive transmission portion 7 protrudes from the side surface of the gear box 71, and this side surface and the storage chamber 70. A sprocket 79 which is an input side drive transmission wheel is attached to the projecting end between the side surfaces. The sprocket 79 and the drive transmission wheel 74 are attached to a coaxial rotation input shaft 73.
30 is an endless roller as an interlocking transmission means between the sprocket 54 of the rotary drive main transmission shaft 52 located at the rightmost end of FIG. 30 and the sprocket 79 of the input side drive transmission portion 7 located at the leftmost end. The chain 6 is looped, and the sprocket 79 of the other input side drive transmission unit 7 is engaged with the roller chain between the two sprockets.
For this reason, when the sprocket 54 of the rotational drive main transmission shaft 52 is rotationally driven, the sprocket 79 of each input side drive transmission portion 7 is also driven and rotated, and the drive transmission wheel 74 is also rotated through the rotational input shaft 73. Each drive roller 13 can be rotated through.

In FIG. 1 and FIG. 29, in order to enable the automatic drive roller conveyor RCm1 and the automatic drive roller conveyor RCm2 to be linked, an intermediate rotational drive transmission shaft 9 is disposed between them.
The intermediate rotation drive transmission shaft 9 is formed by two divided rotation transmission shaft portions 91 and 92 and a spline moving collar 93 connecting the end portions of the butted shaft portions. Universal joints 94 and 95 are attached to one end portions of the rotation transmission shaft portions 91 and 92, and screw portions at the other end portions are screwed into the spline moving collar 93. The intermediate rotational drive transmission shaft 9 can be attached to and detached from the socket 53b of the rotational drive main transmission shaft 52 of the roller conveyor body 1A1 via one universal joint 94. The intermediate rotational drive transmission shaft 9 can be attached to and detached from a socket (not shown) of the rotational drive main transmission shaft 52 of the roller conveyor 1A2 via the other universal joint 95.
When the roller conveyor main bodies 1A1 and 1A2 are connected by the intermediate rotation drive transmission shaft 9, a control means is provided to enable synchronization of driving of the driving devices 2M1 and 2M2, although not shown.

  The roller conveyor RC shown in FIG. 1 is a known one and is a non-automatic drive type. The roller conveyor main body RC1 of the roller conveyor RC is stored in an embedded frame R installed on the floor surface Fa, and includes a plurality of conveyor units 100. The roller conveyor main body RC1 can project the roller frame 102 having the idling roller 101 upward from the floor Fa by lifting / lowering operation means (not shown). It is possible to carry in / out the cargo using the pallet for cargo using the idle roller 101 while being exposed on the floor surface Fa.

Next, the usage method will be described.
Carrying pallets, etc., with adjacent automatic drive roller conveyor RCm1 and automatic drive roller conveyor RC installed on the floor Fa as one set, and with automatic drive roller conveyor RCm2 and roller conveyor RC as one set Carrying in and out of luggage using materials.
Hereinafter, loading / unloading of luggage by the automatically driven roller conveyor RCm1 and the roller conveyor RC will be described.
The roller conveyor body 1A1 and the roller conveyor body RC1 are stored in the embedded frame R in advance.
Preliminary work for loading cargo will be described.
In the roller conveyor body 1A1, the lifting handle H is inserted from the outside of the base end portion (lower end portion in FIG. 4) of the outer roller support frame 11 through the insertion recess 11e and the insertion hole 15d1 which form a single insertion hole, The tip is inserted into the socket 31a of the lifting / lowering operation unit 31 in the inner roller traveling frame 16 as shown by a chain line in FIG. By rotating the lifting / lowering handle H after insertion, the rotational force of the socket 31a of the lifting / lowering operation unit 31 is transmitted to the operating screw shaft 32 via the transmission gear mechanism, and is screwed to the operating screw shaft inside. The movable portion 33a of the holding portion 33 is moved toward the left in FIG. A lift-up joint 34 is connected to the movable portion 33 a via a lift-up operation pin 35, and a support plate portion 11 b of the outer roller support frame 11 is connected to the lift-up joint through a holding pin 36.
Therefore, as the movable portion 33a moves, the outer roller support frame 11 and the inner roller support frame 12 are pulled in the same direction as the movable portion, and the wheel portion 13a of the driving roller 13 and the wheel portion 14a of the idling roller 14 are respectively outside. The roller travel frame 15 and the inner roller travel frame 16 travel along the inclined portions 15c1 and 16c1 of the travel guide portions 15c and 16c, and the inner and outer roller support frames rise together. Thereafter, when the wheel portions 13a and 14a reach the stop portions 15c2 and 16c2 of the traveling guide portions 15c and 16c of the outer roller traveling frame 15 and the inner roller traveling frame 16, the rotational operation for ascending by the lifting handle H is performed. To stop. Due to this stop, the upper end portions of the driving roller 13 and the idling roller 14 are projected on the floor surface Fa (FIG. 20), so that the loaded cargo can be carried into the cargo compartment F.
Also in the roller conveyor main body RC1 shown in FIG. 1, the roller frame 102 is lifted by using the raising / lowering operation means so that the idle roller 101 is exposed above the floor Fa, so that the luggage can be carried in by the idle roller. To do.

Explain how to load your luggage.
When the driving device 2M1 of the automatic drive type roller conveyor RCm1 is driven, the driving force is transmitted as the rotational force to the rotational drive transmission shaft 51 and the rotational drive main transmission shaft 52 shown in FIGS. Since the sprocket 54 of the rotary drive main transmission shaft 52 is rotationally driven, the sprockets 79 of all the input side drive transmission units 7 are also rotated by the roller chain 6. Since the drive transmission wheel 74 attached to the rotation input shaft 73 and the driven transmission wheel 75 linked thereto are also rotationally driven by the rotation of the sprocket 79 of each input side drive transmission unit 7, the driven shaft 17 a of the driven transmission wheel 75. Each drive roller 13 is rotationally driven through.
If each drive roller 13 is rotationally driven, it is rotationally driven if it is placed across the pallet carrying the load between the roller conveyor main body 1A1 and the roller conveyor main body RC1 from the entrance side of the cargo compartment F. By the roller and the idling roller 14, the load is automatically and smoothly conveyed from the base end portion of the roller conveyor on the entrance side to the back of the luggage compartment F.

  When unloading a load, the drive device 2M1 reverses the direction of rotation of each drive roller 13 so that the load is automatically retracted and unloaded from the load room.

  When the drive roller 13 is automatically driven, the rotational force of the drive transmission wheel 74 is transmitted to the driven transmission wheel 75 through one of the first and second intermediate transmission wheels 76 and 77. If necessary, the drive roller 13 is driven. It may be desirable to use an idle roller. In such a case, as described above, if the gear box 71 of each input side drive transmission unit 7 is moved to the right from the position of FIG. 36A to the position of FIG. As shown in FIG. 35, since the first and second intermediate transmission wheels 76 and 77 are not engaged with the driven transmission wheel 75, the interlocking relationship between the drive transmission wheel 74 and the driven transmission wheel 75 is cut off. It will be. As a result, the driving roller 13 becomes the same roller as the idling roller 14 for receiving the load of the load.

  In the roller conveyor main body RC1 shown in FIG. 1, the elevating operation means 3 (FIG. 17) is used to move the outer roller support frame 11 and the inner roller support frame 12 of the roller conveyor main bodies 1A1 and 1A2 up and down. The storage chamber 70 is also moved up and down following the operation of the two roller support frames.

As an example of the arrangement of the automatic drive roller conveyors, in the example shown in FIG. 1, the roller conveyor RC and the automatic drive roller conveyor RCm1 according to the present invention are combined on the left side with the center of the cargo compartment F as the center, and the roller conveyor RC on the right side. Although the automatic drive type roller conveyor RCm2 according to the present invention is combined, the arrangement example is not necessarily limited to this example.
For example, in the example shown in FIG. 37, the roller conveyor main bodies 1A1 and 1A2 of the automatic drive type roller conveyors RCm1 and RCm2 according to the present invention are arranged in two rows adjacent to each other in the luggage compartment F, and the pallet for cargo is provided on both rollers. It is good also as a structure straddling between conveyor main bodies.
In FIG. 37, regarding the reference numerals indicating the components of the automatically driven roller conveyors RCm1 and RCm2, the reference numerals “C1 to C5” indicating the conveyor sections in the roller conveyor main bodies 1A1 and 1A2, the reference numerals “2M1 and 2M2” indicating the driving devices, and the drive The reference numerals “5A1 and 5A2” indicating the transmission means, “9” indicating the intermediate rotational drive transmission shaft, and “93” indicating the spline movement color are omitted.
In the example shown in FIG. 38, the roller conveyor main body 1A1 of the automatic drive type roller conveyor RCm1 according to the present invention and the roller conveyor main body RC1 of the roller conveyor RC are disposed on both sides of the roller conveyor main body in the cargo compartment F. And it is good also as a structure which the pallet for cargoes straddles over all the roller conveyor main bodies.
In FIG. 38, regarding the reference numerals indicating the components of the automatic drive roller conveyor RCm1, the reference numerals “C1 to C5” indicating the conveyor portion in the roller conveyor main body 1A1, the reference numeral “2M1” indicating the driving device, and the reference numeral “2” indicating the drive transmission means. It is omitted except for “5A1”. Further, regarding the reference numerals indicating the constituent parts of the roller conveyor main body RC1 in the roller conveyor RC, the reference numeral “100” indicating the conveyor section, the reference numeral “101” indicating the idling roller, and the reference numeral “102” indicating the roller frame are omitted. .

Since both the outer roller support frame 11 and the inner roller support frame 12 use a mountain-shaped member with the opening facing downward, the strength of each frame is reinforced by the overlapping of the upper plate portions 11a and 12a. However, the inner roller support frame does not necessarily use a mountain-shaped member, and the support plate portion 12b may protrude downward from the inner surface of the upper plate portion 11a of the outer roller support frame. In this case, the upper plate portion of the inner roller support frame 12 is also used as the upper plate portion 11a of the outer roller support frame 11. In the case of sharing, a manufacturing method by forming a pressing die is employed, for example.
By making the width of the drive roller 13 dedicated for carrying the loaded luggage wider than that of the idle roller 14 for receiving the load of the loaded luggage, the cargo can be conveyed smoothly and occupied by the rollers of the roller conveyor bodies 1A1 and 1A2. The load can be reduced, and the weight of the roller conveyor body can be reduced. Of course, both the driving roller 13 and the idling roller 14 may have the same width. Since the drive roller 13 is formed with grooves 13b1 and 13b2 in a direction crossing the width direction of the roller, the surface is provided with appropriate irregularities for preventing lateral displacement of the load with respect to the carrying direction when carrying the loaded load. It is possible to have the straightness of.
In the elevating / lowering operation means 3, the inner and outer roller support frames 11 and 12 can be moved up and down and translated by reciprocating the movable part 33a using the elevating handle H. good.
For example, the drive transmission wheel 74 and the driven transmission wheel 75 may be directly meshed with each other with respect to the transmission mechanism by the gears in the input side drive transmission unit 7, and the intermediate transmissions such as the first and second intermediate transmission wheels 76 and 77 are not necessarily required. You do not have to use a car. Further, although it is not always necessary to provide the connection means 8 for the drive transmission wheel 74 and the driven transmission wheel 75, if this connection means is used, it is possible to switch between driving rotation and idling of the drive roller 13. The versatility of the roller conveyor can be made wider. In addition, if the switching operation is automatically managed by the control device, when the load carrying speed is faster than the driving rotation speed of the driving roller 13, it is switched to idle, thereby contributing to prevention of failure of the roller conveyor.
By providing a disconnecting means 8 that acts as a clutch, and by using a motor with a brake as the power source of the driving devices 2M1 and 2M2, automatic driving of the loaded baggage when it is impossible to drive due to an electrical failure or the convenience of the loaded baggage In the case of using no loading, the power source of the driving roller 13 can be disconnected and used as an ordinary roller conveyor, so there is an advantage that a versatile cargo loading method can be adopted.
Since the input side drive transmission section 7 is provided at an appropriate interval on the entire length of the roller conveyor main bodies 1A1 and 1A2, and the drive roller 13 interlocked with the roller chain 6 is driven, the seat height is low within the limited seat height. Loads can be loaded automatically.
