Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling path and a traveling rail of a conveyor, and more particularly to a traveling path and a traveling rail suitable for a monorail type conveyor.

[0002]

2. Description of the Related Art Conventionally, a monorail type transfer device has been proposed and implemented which moves along a rail installed on a ceiling and transfers a load from a station in a factory or a warehouse to another station. As this type of transport device,
For example, Japanese Utility Model Laid-Open No. 2-142370 discloses a device in which a conveying device 51 is supported in a suspended state on a rail 52 having a substantially U-shaped cross section as shown in FIG. Transport device 5
The traveling roller 53 of No. 1 is the upper surface 52 of the lower horizontal portion of the rail 52.
Rolls with a as the running surface. Both lower sides 5 of rail 52
2b is a guide surface of the lower side roller 54, and both side surfaces of the downward protruding piece 52c provided on the upper portion of the rail 52 are guide surfaces of the upper side roller 55. A trolley wire 56 is arranged on the inner surface of the rail 52.

In Japanese Utility Model Laid-Open No. 5-22246, FIG.
As shown in FIG. 5, a transfer device 58 having a substantially U-shape that fits into a rail 57 having a substantially I-shaped cross-section from one side is mounted on the rail 57 via a drive wheel 59 rolling on the upper surface of the rail 57.
There is disclosed a device supported by. The transport device 58 includes a backup roller 60 that rolls on the lower surface of the rail 57, and a steadying roller 61 that sandwiches the upper and lower portions of the rail 57 from the left and right sides. Further, a power feeding rail unit (trolley wire) 62 is arranged at the center of the rail 57.

[0004]

In the former conveying device 51, since the trolley wire 56 is arranged above the traveling surface of the traveling roller 53, the abrasion powder of the trolley wire is accumulated on the traveling surface of the traveling roller 53. . As a result, the traveling roller 53 slips during traveling or braking, and the stop position accuracy of the transport device 51 deteriorates. Also, the traveling roller 53 and the rail 5
There is also a problem that the wear of No. 2 is promoted.

If a contactless power feeding method utilizing electromagnetic induction is adopted instead of the contact method using a trolley wire and a current collector as the power feeding method, the above problem is eliminated because the trolley wire is not worn. However, in the case of the non-contact power feeding method, when the power line is arranged inside the rail 52 as in the former device, the layout is restricted in order to avoid interference between the traveling mechanism section including the traveling roller 53 and the power receiving section. There is a problem.

In the latter transfer device 58, the power supply rail unit (trolley wire) 62 is disposed below the traveling surface of the drive wheels 59, and therefore the above-mentioned problem does not occur. However, since a steadying roller 61 that sandwiches the lower portion of the rail 57 from both the left and right sides is arranged below the power feeding rail unit 62, wear powder of the trolley wire is generated between the steadying roller 61 and the rail 57. There is a problem that the anti-sway roller 61 is likely to be worn due to the adhesion. Further, since the drive wheel 59 rolls on the upper surface of the rail 57, the space occupied by the transport device 58 above the drive wheel 59 becomes large and the installation position of the rail 57 is easily restricted.

The present invention has been made in view of the above problems. A first object of the present invention is that when power is supplied by a trolley wire, abrasion powder of the trolley wire is accumulated on the traveling portion to have an adverse effect. The present invention is to provide a traveling path of a carrier device that can prevent the above-mentioned problems and is not restricted by the layout of the traveling unit and the power receiving unit even in the case of the non-contact power supply system.
It is an object of the present invention to provide a traveling rail of a conveyor suitable for forming the traveling path.

[0008]

In order to achieve the first object, the invention according to claim 1 is provided with a traveling wheel rolling on a track, and is provided with a power feeding portion arranged along the track. A partition wall is formed along a traveling portion on which traveling wheels roll, which is a traveling path of a power supply device, and a power feeding portion is provided on a side of the partition wall opposite to a side corresponding to the traveling portion.

According to a second aspect of the present invention, the power feeding section is a trolley wire. In the invention according to claim 3, the power feeding unit is a power line for non-contact power feeding. Further, in order to achieve the second object, in the invention according to claim 4, at least the lower support portion that supports the traveling wheel and the upper support portion that supports the guide roller are connected by the connecting portion, and the connecting portion A power supply trolley mounting portion was provided on the side opposite to the side corresponding to the running wheels.

According to the invention described in claim 5, claim 4
In the invention described in (1), a ridge having a tip projecting to the outside of the power feeding trolley mounted on the mounting portion is formed on the power feeding trolley mounting portion side of the connecting portion so as to sandwich the mounting portion.

[0011]

According to the first aspect of the invention, the carrier device travels on the track using the electric power supplied from the power supply unit as the power source.
The traveling wheels of the carrier roll on the traveling portion of the traveling path. The transfer device receives power from a power supply unit provided on a side opposite to a side of the partition wall formed along the traveling unit, the side corresponding to the traveling unit.

According to the second aspect of the present invention, since the power feeding portion is the trolley wire, the trolley wire is worn and the abrasion powder is generated during the traveling of the carrying device. However, since the trolley wire is provided on the side opposite to the side of the partition wall formed along the running portion that corresponds to the running portion, abrasion powder is prevented from accumulating on the running portion.

According to the third aspect of the invention, since the power feeding unit is the power line for non-contact type power feeding, the power line is not worn when the carrier device is running. Since the power feeding unit is provided on the side opposite to the side corresponding to the traveling unit of the partition wall formed along the traveling unit, there is no interference between the power receiving unit equipped in the transport device and the traveling mechanism unit.

In the invention according to claim 4, the traveling wheels move while being supported by the lower support portion. In addition, the guide roller provided in the transport device moves along the upper support portion.
The trolley wire or the power line for non-contact type power feeding is attached to a power feeding trolley mounting portion provided on the side opposite to the side corresponding to the running wheels of the connecting portion.

According to the fifth aspect of the present invention, the tip of the protrusion provided on the side of the power feeding trolley mounting portion of the connecting portion is in a state of protruding to the outside of the power feeding trolley mounted on the mounting portion. Therefore, even if the traveling rails are lined up or stacked in abutting state with the power feeding trolley attached during transportation, the power feeding trolley is located in the space surrounded by the protrusions and the connecting portion, and damage is prevented.

As shown in FIGS. 1 and 2, the main body portion 12a
The bearing 18 is fixed to the upper part of the
1 is rotatably supported on the horizontal portion 2b of the standing portion 2a via a support shaft 19. The support shaft 19 is arranged at a position where the axis of the support shaft 17 substantially coincides with the vertical center line of the driven wheel 11. Both supporting portions 14a and 14b are positioned so as to sandwich the driven wheel 11 between the upper and lower sides, and a pair of guide rollers 20a and 20b are rotatably supported at both front and rear ends thereof. The guide roller 20a is arranged so as to sandwich the guide protrusion 3a, and the guide roller 20b is arranged so as to sandwich the upright portion 2a. The connecting portion 4 has a plurality of trolley wires 21.
A power feeding trolley 21 as a power feeding portion equipped with a is attached in a state of being hooked on the hooking protrusions 4a and 4b.

That is, in the traveling rail 1 as the track of the conveying device 7, the lower support portion 2 supports the traveling wheel (driven wheel 11) and the guide roller 20b, and the upper support portion 3 supports the guide roller 20a. The connecting portion 4 serves as a partition wall, and the supporting portions 2 and 3 side with the connecting portion 4 interposed therebetween serve as the traveling portion of the traveling path of the transport device 7.

As shown in FIGS. 1 and 2, a support bracket 22 is attached to the tip of the upper mounting portion 13a, and the support bracket 22 receives power and signals from the trolley wire 21a of the power feeding trolley 21. A power collection unit 23 that receives the power is supported. In FIG. 1, the power collection unit 2
3 is simplified from FIG.

The bracket 10 is also constructed in the same manner as the bracket 12, and is also supported by the same construction via the block 16 and the support shaft 17 so as to be rotatable relative to the carrier 8. A traveling motor 24 is fixed to the upper portion of the main body portion 10a of the bracket 10 with bolts 25 and nuts 26. A motor with a speed reducer is used as the traveling motor 24, and the drive wheel 9 is supported on the output shaft 24a of the traveling motor 24 so as to be integrally rotatable. The traveling motor 24 is arranged so that the drive wheels 9 can roll on the horizontal portion 2b and the axis of the support shaft 17 is substantially aligned with the vertical center line of the drive wheels 9. Further, in the pair of support portions 14a and 14b mounted on the main body portion 10a so as to sandwich the drive wheel 9 between the upper and lower sides, a pair of guide rollers 20a and 20b are provided at the front and rear ends thereof as in the case of the bracket 12.

There is.

Next, the operation of the device configured as described above will be described. The carrier device 7 receives power and signals from the trolley wire 21a via the current collecting unit 23. When the traveling motor 24 is driven by using the electric power as a power source,
The drive wheel 9 rolls on the horizontal portion 2b and the carrier 8 moves. Since the current collecting unit 23 slides along the trolley wire 21a as the carrier 8 moves, the trolley wire 21a is worn and the abrasion powder falls. Drive wheel 9 and driven wheel 1
Since the running portion on which 1 etc. rolls is isolated from the power feeding side by the connecting portion 4, the abrasion powder of the trolley wire 21a is reliably prevented from accumulating on the running portion. Therefore, unlike the conventional device in which wear debris accumulates on the running portion, the drive wheels 9 and the driven wheels 11 slip due to the action of the wear debris during running and braking, and the wear of both wheels 9 and 11 and the running rail 1 is accelerated. Is prevented.

Since the guide rollers 20a and 20b mounted on the brackets 10 and 12 sandwich the rising portion 2a and the guide ridges 3a of the traveling rail 1, the curved portion of the traveling rail 1 as shown in FIG. At bracket 10,
12 is rotated according to the curve, and the carrier 8 moves along the traveling rail 1. When the brackets 10 and 12 are rotated, the output shaft 24a and the support shaft 19, which are the support shafts of the drive wheels 9 and the driven wheels 11 supported by the brackets 10 and 12, rotate in a horizontal plane. Brackets 10 and 11 are support shafts 1.
7, the support shaft 17 is arranged so that the axis line of the support shaft 17 coincides with the vertical center line of the drive wheel 9 and the driven wheel 11, so that the support shafts of the drive wheel 9 and the driven wheel 11 are horizontal. Even if the vehicle turns, the drive wheels 9 and the driven wheels 11 continue rolling with almost no slip. Then, the driving wheel 9 and the driven wheel 11
The direction of travel changes according to the curve. Drive wheel 9
Also, since the driven wheels 11 hardly slip, wear of the drive wheels 9 and the driven wheels 11 is suppressed, and noise is reduced.

Since the current collecting unit 23 is supported by the support bracket 22 fixed to the bracket 12, the current collecting unit 23 is turned along the curve in the curved portion of the traveling rail 1. As a result, the sliding contact state of the current collecting unit 23 with the trolley wire 21a is stably ensured, and power and signals can be received in a stable state.
The brush 28 slides along the trolley wire 21a as the transport device 7 moves to clean the trolley wire 21a. The brush 28 has a support bracket 27 on the bracket 10.
The brush 28 is swung along the curve in the curved portion of the traveling rail 1, so that the trolley wire 21a in the curved portion can be reliably cleaned.

Further, in the traveling rail 1 of this embodiment, the tips of the projections 5 and 6 provided on the mounting side of the power feeding trolley 21 are projected to the outside of the power feeding trolley 21 mounted on the traveling rail 1. Is in a state. Therefore, even if a large number of traveling rails 1 are arranged side by side in contact with each other with the feeding trolley 21 attached to the traveling rail 1, the feeding trolley 21 is surrounded by the protrusions 5, 6 and the connecting portion 4. It is located in the space and prevents damage. As a result, it becomes easy to transport the traveling rail 1 with the power feeding trolley 21 attached, and the assembling at the construction site becomes easy.

(Second Embodiment) Next, a second embodiment will be described with reference to FIG. This embodiment is different from the above-mentioned embodiments in that electric power is supplied by a contactless power feeding method. That is, the traveling rail 1 is the same as that of the above-described embodiment, but the configurations of the power feeding unit and the power receiving unit are different. The electric power line 29 that constitutes the power supply unit is extended along the traveling rail 1 via a support tool 30 that is retained by the retaining projections 4a and 4b of the traveling rail 1. Further, the yoke 32 around which the coil 31 constituting the power receiving portion is wound is supported by the support brackets 33 attached to the brackets 10 and 12, respectively. The support bracket 33 is attached to the brackets 10 and 12 instead of the support brackets 22 and 27 in the above embodiment. And the power line 29
When the coil 31 traverses the magnetic field formed around the coil 31, a current flows through the coil 31, and power is supplied from the power line 29 to the power receiving unit side.

Since the power feeding section is the power line 29 for non-contact type power feeding, the power line 29 is not worn when the carrier device 7 is running. Since the power supply unit is provided on the side opposite to the side corresponding to the traveling unit of the partition wall formed along the traveling unit, there is no interference between the power receiving unit equipped in the transport device 7 and the traveling mechanism unit. Further, since the rail ridges reduce the vertical leakage of the magnetic field formed by the power line 29, the efficiency of the contacted power feeding is improved.

The present invention is not limited to the above embodiment, but may be embodied as follows, for example. (1) The drive wheel 9 and the driven wheel 11 may be configured to roll on the lower horizontal portion of the substantially U-shaped rail 2 as in the conventional example. Further, instead of providing the guide rollers 20a and 20b on the brackets 10 and 12 in the upper and lower pairs, respectively, one of the support portions 14a and 14b may be omitted. In this case, the structure is simpler than that of the embodiment.

(2) The protrusions 5 and 6 projecting to the power feeding side may be omitted. Further, instead of the mounting structure for hooking the power feeding trolley 21 on the hooking protrusions 4a, 4b, a screw hole or a hole is provided in the connecting portion 4, and the power feeding trolley 21 is fixed to the connecting portion 4 with a bolt or a bolt and a nut. It may be configured.

(3) Instead of the structure in which the carrier 8 is supported on the traveling rail 1 in a suspended state, the carrier 8 is used.
It may be configured to move above. In this case, the present invention can be applied not only to the carrier device 7 that travels on the traveling rail 1 laid on the ceiling but also to the carrier device that travels on the rail laid on the floor surface.

Inventions other than those described in the claims that can be grasped from the respective embodiments and modifications will be described below along with their effects. (1) In the invention according to claim 4 or claim 5, a hooking protrusion extending along the connecting portion is provided as a power supply rail mounting portion. In this case, the feeding trolley can be easily attached.

[0034]

As described in detail above, the first to third aspects of the invention are described.
According to the invention described in (1), wear powder of the trolley wire does not accumulate on the running part, and it is possible to prevent deterioration of stop position accuracy and acceleration of wear of running wheels and rails due to the buildup of wear powder. Also, in the case of the contactless power feeding method, there is no limitation on the layout of the traveling unit and the power receiving unit.

Further, according to the inventions described in claims 4 and 5, it is possible to easily form a traveling path exhibiting the effects of the inventions described in claims 1 to 3. Also, claim 5
According to the invention described in (1), even when the traveling rails are lined up or stacked in a state of abutting each other with the power supply trolley attached, the power supply trolley is not damaged and the power supply trolley is attached. Transport rails will be easier to transport and assembly at the construction site will be easier.
