[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a storage for temporarily accumulating and storing a hybrid transport trolley capable of selectively using a wheel transport function and a skid transport function according to a transport mode of a transport line until a request from a next process line. Conveyor.
[0002]
[Prior art]
Conventionally, as a storage conveyor for transporting a carrier on which a work such as an automobile body is mounted in a factory, various storage conveyors according to the form of the carrier, the form of the transport line, and the like are used. The hybrid storage conveyor for storage transport of a hybrid transport vehicle that can use the wheel transport function and the skid transport function properly according to the line configuration of the transport line is currently in the development stage for practical use. is there.
[0003]
FIGS. 6 to 9 show an example of a hybrid type storage conveyor for carrying and transporting a work W such as an automobile body, which has been painted on a transport line in a painting process, to a transport line in a drying process comprising an oven furnace. 6 is a cross-sectional view thereof, FIG. 7 is a side view thereof, FIG. 8 is a view showing one mode of the transfer process, and FIG. 9 is a change of the bogie length of the hybrid transport bogie. FIG. 5 is a diagram showing an arrangement interval between a driving roller and a bogie detection sensor accompanying the above.
[0004]
Therefore, as shown in FIGS. 6 and 7, a conventional hybrid storage conveyor (hereinafter referred to as “conventional storage conveyor”) includes a pair of rails C for guiding traveling wheels B of a hybrid transport vehicle A. Is mounted between a plurality of support brackets D erected at predetermined intervals along the transport direction on the floor of the transport path, and a drive roller device F for frictionally driving the transport skid E of the hybrid transport vehicle A is provided. And a hybrid transport vehicle A is attached to one of the plurality of fixed-length connecting beam members G spanning in the width direction of the rail C. The conveyor unit I is formed by integrally assembling a bogie detection sensor H for detecting whether or not the vehicle is present above the vehicle.
[0005]
As shown in FIG. 7, a plurality of rails C of the conveyor unit I and a plurality of rails of the conveyor unit I which are adjacent to each other in the transport direction indicated by phantom lines are connected in series by connecting pieces J to constitute a series of storage conveyors. are doing.
[0006]
[Problems to be solved by the invention]
However, the conventional storage conveyor as described above has the following problems.
[0007]
In the conventional storage conveyor, since the unit length L1 of the conveyor unit I is equal to the standard carriage length L2 of the hybrid transport vehicle A, the drive roller device F is disposed along the transport direction and equal to the vehicle length L2 of the hybrid transport vehicle A. In the case where the hybrid transport vehicle A is stopped between the two drive roller devices F due to an operation error, an emergency stop, or the like, as shown in FIG. The transport vehicle A cannot obtain the driving force from these drive roller devices F, F, and is stuck and becomes inoperative.
[0008]
Therefore, in such a case, maintenance must be performed so that the stopped hybrid transport vehicle A can be forcibly engaged with the drive roller device F by manual operation or the like by a worker to obtain a driving force. However, there is a problem that complete automation of storage transport cannot be expected.
[0009]
Further, in the conventional storage conveyor, since the unit length L1 of the conveyor unit I is equal to the standard bogie length L2 of the hybrid transport bogie A, the bogie detection sensor H is arranged along the transport direction to be equal to the bogie length L2 of the hybrid transport bogie A. The hybrid transport vehicle A is located between the two bogie detection sensors H, H due to the detection accuracy of the hybrid transport vehicle A due to the bogie length accuracy of the hybrid transport vehicle A and the mounting accuracy of the detection position. , These two carriage detection sensors H, H should overlap with the one hybrid carrier A and overlap with the subsequent hybrid carrier A. The bogie detection sensor H is no longer engaged.
[0010]
Therefore, when the hybrid transport trolley A, which is no longer involved in the trolley detection sensor H, is located at the end of the storage conveyor line, the storage transport is not performed, but is left behind, and the storage transport is interrupted.
[0011]
Further, in the conventional storage conveyor, when the bogie length of the hybrid transport bogie A is changed as shown in FIG. 9, there are the following problems. Specifically, as shown in FIG. 9A, when the unit length of the ten conveyor units I for knitting the storage conveyor is equal to 4100 mm, which is the standard length of the hybrid transport vehicle A, the drive roller device F The trolley detection sensors H are arranged at an interval of 4100 mm, which is equal to the standard trolley length 4100 mm of the hybrid transport trolley A, depending on the load to be mounted as shown in FIG. If it is necessary to change the model to the hybrid transporting cart A having a longer bogie length of 4800 mm, at least the bogie detection sensor H must be corrected to the arrangement interval of 4800 mm as shown in FIG. 9C. Therefore, the rearrangement of the seven bogie detection sensors H, the removal of two extra bogie detection sensors H, and the extra one drive It had to be carried out recombination work such as removal of La apparatus F.
[0012]
Therefore, the rearrangement work such as the rearrangement and the removal is not only limited by the position to be rearranged because the bogie detection sensor H is assembled to the fixed-length connecting beam member G and is unitized, Even if it is assembled to the fixed-length connecting beam G via various mounting brackets, strict on-site construction accuracy is required so that the rearranged bogie detection sensor H does not malfunction. The construction time is forced, and the advantages such as simple layout change due to the unitization of the conventional storage conveyor are completely lost.On the contrary, the unitization makes the rearrangement work troublesome. Was.
[0013]
Therefore, an object of the present invention is to solve the above-described problems of the prior art, to reliably transmit the propulsive force to all the hybrid transport vehicles carried into the storage transport line, and to realize the hybrid transport vehicle. An object of the present invention is to provide a hybrid storage conveyor capable of easily performing the work of rearranging the arrangement intervals of the bogie detection sensors even if the length is changed.
[0014]
It is a further object of the present invention to provide a hybrid storage conveyor capable of reliably detecting all hybrid transport vehicles carried into a storage transport line for each vehicle.
[0015]
A further object of the present invention is to continuously and smoothly carry out storage transport of all hybrid transport vehicles carried into the storage transport line even if there is a slight variation in the length accuracy of the hybrid transport vehicle and the mounting accuracy of the detection position. It is to provide a hybrid storage conveyor that can be used.
[0016]
[Means for Solving the Problems]
The hybrid storage conveyor according to the first aspect of the present invention includes a plurality of hybrid transport vehicles having a pair of left and right transport skids and front, rear, left and right traveling wheels, and a plurality of conveyor units in which a transport roller driving roller device is fixed. In a hybrid storage conveyor in which storage is transported by a number of trolley detection sensors individually corresponding to the drive rollers for the transport skid, the unit length of the conveyor unit is shorter than the standard trolley length of the hybrid transport trolley, and the trolley detection sensor is The above-mentioned problem has been solved by being mounted so that it can be relocated along the wiring aggregation bridge member penetrating in the unit connection direction.
[0017]
The hybrid storage conveyor according to the second aspect of the present invention is characterized in that, in addition to the first aspect of the present invention, an insensitive area for the bogie detection sensor is provided at both ends of the hybrid transport bogie. Was further solved.
[0018]
A hybrid storage conveyor according to a third aspect of the present invention is the hybrid storage conveyor according to the first or second aspect, further comprising a drive roller device for a transport skid corresponding to a bogie detection sensor that cannot detect the hybrid transport bogie. The above problem is further solved by forcibly driving the vehicle by a bogie detection signal of a bogie detection sensor corresponding to the transport skid driving roller device on the downstream side of the transport until a predetermined time elapses.
[0019]
In the present invention, the “standard bogie length of the hybrid carrier” means the bogie length of the hybrid carrier that is most commonly used in the hybrid storage conveyor of the present invention. It does not mean the bogie length.
[0020]
In addition, the bogie detection sensor provided in the hybrid storage conveyor of the present invention may employ any type of detection sensor such as a photoelectric sensor or a proximity sensor as long as it can reliably detect the presence of the bogie. No problem.
[0021]
The drive roller device for a transport vehicle disposed on the hybrid storage conveyor according to the present invention operates based on the vehicle detection signal of the vehicle detection sensor, and abuts against the transport skid of the hybrid transport vehicle to perform friction driving. As long as it has a drive roller capable of performing the above-mentioned operations, its specific device form may be any.
[0022]
In addition, the bridge member for wiring aggregation used in the hybrid storage conveyor of the present invention can collectively hold various wirings related to the conveyor in an orderly manner, and the trolley detection sensor can be freely relocated along the unit connecting direction. As long as it is a member having any form, such as a wiring centralizing duct and a wiring centralizing beam member, it does not matter.
[0023]
Further, the hybrid transport trolley applied to the hybrid storage conveyor of the present invention is provided with a pair of left and right transport skids that are elongated in the transport direction on the lower bottom surface of the trolley body that travels independently on the rail by front and rear and left and right traveling wheels. A bogie traction engaging portion is provided at the center in the width direction of the lower bottom surface of the bogie main body, and a work can be mounted on the bogie main body so that both wheel conveyance and skid conveyance can be performed.
[0024]
The transport skid of the hybrid transport vehicle transported by the hybrid storage conveyor of the present invention is a transport guide roller of a normal transport line, a transport drive roller, or a transport roller of a storage transport line, which is transported to transport the truck body. Therefore, a pair of left and right rollers abuttingly extended in the transport direction on the lower bottom surface of the carriage main body, and is slightly longer than the length in the transport direction of the workpiece mounted and transported on the hybrid transport carriage. , The same length.
[0025]
[Action]
In the hybrid storage conveyor of the present invention, the hybrid transport vehicle is guided along a pair of rails while front, rear, left and right traveling wheels support the weight of the bogie body, and a pair of one or one side provided on the lower bottom surface of the bogie body. When the transport skid is frictionally driven by the transport skid drive roller device, the transport skid travels in a state in which the bogie supporting force and the bogie propulsion force are shared.
[0026]
Therefore, the hybrid storage conveyor of the present invention is configured such that the unit length of the conveyor unit is shorter than the standard bogie length of the hybrid carrier, and the bogie detection sensor can be freely moved along the wiring aggregation bridge member penetrating in the unit connection direction. By being attached, the drive roller device for the transport skid is arranged at an interval shorter than the standard bogie length of the hybrid transport vehicle, so that all the hybrid transport vehicles carried into the storage transport line are provided. In addition, the drive roller device for the transport skid is engaged on a truck basis to reliably transmit the propulsion force for each truck, so-called one-to-one drive transmission function, and the truck length of the hybrid transport truck is changed. The trolley detection sensor can be freely moved along the bridge member for wiring aggregation even if there is Tsu correspondence between de drive roller apparatus and the carriage detection sensor is conveniently corrected.
[0027]
Further, in the hybrid storage conveyor of the present invention, the bogie detection sensor is mounted so as to be relocated along the bridge member for wiring aggregation, and insensitive areas for the bogie detection sensor are provided at both ends of the hybrid carrier. Thus, the bogie detection sensors are engaged with all the hybrid transport bogies in the storage transport line in units of the bogies, and perform a so-called one-to-one bogie detection function of reliably detecting each bogie.
[0028]
In addition, the hybrid storage conveyor of the present invention is characterized in that the transport skid driving roller device corresponding to the bogie detection sensor that failed to detect the hybrid transport vehicle is replaced with a bogie detection sensor corresponding to the transport skid driving roller device on the downstream side of the transport. The vehicle is forcibly driven until a predetermined time has elapsed by the bogie detection signal, so that even if there is a slight variation in the bogie length accuracy of the hybrid carrier and the mounting accuracy of the detection position, all the hybrid carriers in the storage carrier line can be smoothly moved. A so-called forced drive function for transporting the storage is exhibited.
[0029]

[0030]
First, FIG. 1 is a cross-sectional view showing a hybrid storage conveyor of the present embodiment, FIG. 2 is a plan view thereof, FIG. 3 is a side view thereof, and FIG. FIG. 5 is a diagram illustrating an aspect, and FIG. 5 is a diagram illustrating an arrangement interval between a transport skid driving roller device and a bogie detection sensor in accordance with a change in the bogie length of the hybrid transport bogie.
[0031]
Therefore, the hybrid storage conveyor according to the present embodiment includes a pair of rails 1 for guiding traveling wheels B of a hybrid transporting vehicle A as shown in FIG. A conveyor skid drive roller device 3 for transmitting a propulsion force as a conveyor by frictionally driving a conveyor skid E of a hybrid conveyor truck A while being bridged between a plurality of support brackets 2 erected at intervals. A conveyor unit 5 that can be connected at a construction site by assembling with one of a plurality of fixed-length connecting beam members 4 spanned in the width direction, and a rail 1 of the conveyor unit 5 and another conveyor adjacent thereto. A plurality of rails 1 of the unit 5 are connected in the transport direction by connecting pieces 6 as shown in FIGS. It has been organized.
[0032]
As described above, the conveyor unit 5 is a unit formed by integrally assembling the rail 1, the support bracket 2, the driving roller device 3 for the transport skid, and the fixed-size connecting beam 4, and has a unit length L1. Is set shorter than the standard bogie length L2 of the hybrid transport bogie A as shown in FIG. 3, that is, the bogie length of the hybrid transport bogie A most commonly used in the hybrid storage conveyor of this embodiment. As shown in (1), the propulsion force can be reliably transmitted to all the hybrid transfer vehicles carried into the storage transfer line in units of the respective vehicles.
[0033]
A bridge member 7 for wiring integration, which is formed of at least one wiring duct penetrating the air space below a number of conveyor units 5 forming the storage conveyor structure as shown in FIGS. 1 to 3, is bridged in the conveyor width direction. It is laid via a large number of fixed-length connecting beam members 3 that have been passed, and various wirings related to the conveyor are organized and held in an orderly manner.
[0034]
Further, a large number of bogie detection sensors 8 are mounted on the wiring duct 7 via a positioning bracket 9 at any position in the transport direction so as to be freely relocated.
[0035]
The truck detection sensors 8 are provided with insensitive areas 10 for the truck detection sensors 8 as shown in FIG. 3 at both ends of the hybrid transport truck, so that all the hybrid transport trucks on the storage transport line can be connected to the respective trucks. A normal photoelectric sensor, a proximity sensor, or the like is sufficient because the detection can be reliably performed in units.
[0036]
In addition, the plurality of transport skid drive roller devices 3 and the trolley detection sensors 8 as described above are generally controlled on a one-to-one basis, but one of the trolley detection sensors 8 is a hybrid transport trolley A. Is not detected, the driving roller device 3 for the transport skid corresponding to the bogie detection sensor 8 that cannot detect the hybrid transport vehicle A is replaced with the bogie corresponding to the driving roller device 3 for the transport skid on the downstream side of the transport. Although not shown, a control means (not shown) for forcibly driving the hybrid transport vehicle by a detection signal from the detection sensor 8 until a time required to transport one hybrid transport vehicle has passed is provided.
[0037]
Therefore, the so-called forced drive function of smoothly transporting all the hybrid transport vehicles A on the storage transport line even if there is some variation in the vehicle length accuracy of the hybrid transport vehicle A and the mounting accuracy of the detection position is exhibited.
[0038]
Next, a detailed description will be given of the arrangement of the transport skid drive roller device 3 and the bogie detection sensor 8 when changing the bogie length of the hybrid transport bogie A applied to the hybrid type storage conveyor of the present embodiment. It is as follows.
[0039]
As shown in FIG. 5A, the unit length L1 of the ten conveyor units I forming the storage conveyor is 4000 mm, which is shorter than the standard bogie length L2 of 4100 mm of the hybrid carrier A equipped with an automobile body. In this case, the arrangement interval of the trolley detection sensors H is set to 4100 mm, which is equal to the standard trolley length L2 of the hybrid transport trolley A, and the arrangement interval of the drive roller device F is necessarily set to 4000 mm. When it is necessary to change the model to a hybrid transporting cart A having a bogie length of 4800 mm longer than the standard bogie length L2 of 4100 mm, which is commonly used as shown in FIG. 5B, as shown in FIG. With the change of the model, the bogie detection sensors H are corrected to the arrangement interval of 4800 mm. You can respond by performing only recombination work truck detection sensors H by removal of the carriage detection sensor H of rearrangements and extra 2 groups, no burden for removing the driving roller device F.
[0040]
In addition, such rearrangement work such as rearrangement and removal is performed as a unit because the bogie detection sensor H is removably mounted along a wiring aggregation bridge member formed of a wiring duct penetrating in the unit connecting direction. Therefore, there is no restriction on the position to be rearranged, and strict on-site construction accuracy can be ensured so that the relocated bogie detection sensor H does not malfunction, and the construction burden and construction time are significantly reduced. This can alleviate the problem and eliminate problems such as those encountered in conventional storage conveyors.
[0041]
As described above, the hybrid-type storage conveyor of the present embodiment can reliably detect all the hybrid transport vehicles transported to the storage transport line for each vehicle unit and reliably transmit the propulsion force. In addition to this, even if there is a change in the bogie length of the hybrid carrier, the work of rearranging the intervals of the bogie detection sensors can be easily achieved, and the accuracy of the bogie length of the hybrid carrier and the mounting accuracy of the detection position are somewhat reduced. Can smoothly achieve storage transport even with the fluctuations, and the remarkable effect is enormous.
[0042]

By being attached, the propulsion force can be reliably transmitted to each hybrid transport vehicle that has been loaded into the storage transport line on a carriage-by-car basis, and the transport site can be changed even if the length of the hybrid transport vehicle changes. In this case, the bogie detection sensors can be freely and simply rearranged, and the high construction accuracy can be secured without impairing the merits of unitization.
