Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a conveyance device, particularly when the conveyance track is curved or has ups and downs, and more specifically when installed on a dust collection vehicle etc. The present invention relates to a conveying device that can perform dust collection work.

(Prior art) Conventionally, in a dust collection vehicle with a dust storage compartment installed on the loading platform, a worker deposits dust into a dust inlet at the rear of the vehicle, and the dust is placed between two staggered sheets placed in the inlet. One of the plate-shaped swinging members that swings crosswise lifts the dust upward, and then the other swinging member slides into contact with the dust holding surface of this member and sweeps away the dust. It has a structure that discharges dust into the dust storage.

(Problem to be Solved by the Invention) However, in the dust collection vehicle having the above structure, in order for the worker to work in a position close to the dust inlet, the swinging member is continuously moved during dust inlet. They could bite the worker's clothing or, in some cases, even part of the worker's body, and in severe cases, there was a danger that the worker's entire body could become entangled, leading to death.

Therefore, in order to keep workers away from this dangerous area (dust inlet), a dust inlet was installed on the top side of the dust storage chamber, and it was placed in a position corresponding to the conventional dust inlet (lower on the ground, etc.). The above-mentioned danger can be eliminated by transporting the dust to the dust inlet via a transport means and letting it fall into the refrigerator from the inlet, but this transport means has the following problems.

Conveyance means for lifting dust upwards to the input port have limited space, such as vehicles, so devices such as belt conveyors can have a large conveyance capacity, but are difficult to lift irregularly shaped dust, etc. Since the angle of inclination cannot be made as large as possible, it is not suitable for vehicles such as dust-collecting vehicles.

Therefore, the application of a conveyor etc. with packets attached may be considered, but transport means with packets attached to -C require a large space, so in places with restrictions, a conveyor with high transport capacity should be installed. This was extremely difficult. Alternatively, a lifting device such as an elevator can be used, but in this case, the conveyance capacity is extremely poor and it is not practical.

On the other hand, in conventional general conveyance devices, when the conveyance path must be bent or undulated vertically, multiple conveyance means (for example, belt conveyors) adapted to the shape of the conveyance path are used as appropriate. It is possible to convey articles by connecting them together, but in this case, multiple drive systems are required, or the article is transferred from one side to the other at the joint of each conveyance means. Therefore, in order to avoid such a situation in which the conveyed object becomes stagnant during conveyance and cannot be conveyed, for example, the conveying means is designed such that adjacent ends thereof are overlapped in the vertical direction. A structure is adopted in which the articles carried at the end of the preceding conveying means fall onto the downstream conveying means, thereby ensuring conveyance. It was not suitable for transporting unsuitable goods.

The purpose of the present invention has been achieved in view of the above circumstances, and
It can be installed in a relatively narrow area with limited installation space, has high transport capacity and can be applied to the above-mentioned dust collection vehicles, and can safely and reliably transport items even on complicated transport routes. Our goal is to provide a transport device that can.

(Means for Solving the Problems) That is, the above object of the present invention is to provide a plurality of movable bodies movably provided on a loop-shaped track and having at least one pressing portion substantially along the general cross section; By sequentially engaging the movable body between the article conveyance areas by driving means provided along the article conveyance area of the track, the movable body is sequentially moved so that at least the pressing part is separated at a constant interval, This is achieved by a conveyance device characterized in that the movable bodies are in contact with each other in a track region other than the article transport region, so that the pressing force of the driving means is transmitted and circulates on the track. In addition, a plurality of movable bodies each having a pressing portion substantially along at least the conveying cross section are movably provided on the loop-shaped track and are mutually connected by a flexible connecting member, and the driving means is connected to the track. The movable body is located close to the article conveyance area so that a part of the movable body can be pulled by the connecting member between the article conveyance areas, and the movable body is arranged so that the movable bodies are connected to each other in a track area other than the article conveyance area. This can also be achieved by a conveying device characterized in that it is configured to circulate on the track by abutting at intervals shorter than the length of the connecting members.

(Embodiment) Hereinafter, one embodiment of the conveying device of the present invention will be explained in detail based on the drawings.

In this embodiment, a case will be described in which the present invention is applied to a dust collection vehicle, but naturally the present invention is not limited to this embodiment at all.

FIG. 1 shows a side view of the entire dust collection vehicle, and FIG. 2 shows a plan view thereof.

In the figure, in this dust collection vehicle 1, a dust storage compartment 2 having a conventional road-side external appearance is installed on the loading platform, and the wall surface of the dust storage compartment 2 at the rear of the vehicle has a point B integrated therein. It can be used as a fulcrum and opened upwards (in the C direction). or,
The dust storage cabinet 2 is provided with an input port 3 which is opened for suction and discharge on the upper surface near the front, and a press plate 5 provided inside the dust storage cabinet 2 so as to be movable rearward by hydraulic means 4 is installed. have. Note that the pressing plate 5 compresses jΔ put into the refrigerator between it and the rear wall surface.

The conveyance device 10 of the present invention is attached along the rear wall surface and the upper wall surface of the outer wall surface of the dust storage 2.

The conveying device 10 will be explained in conjunction with the enlarged view shown in FIG. 3. The conveying device 10 includes two loop-shaped parallel guide rails 11 disposed along the outer wall surface of the dust storage 2, and the guide rails. 11 and is provided movably along the guide rail 11, and a driving means 13 for driving the movable bodies 12.

1); The drive means 13 described in I is an endless drive means disposed in a partial area of the conveyance path 14 formed between the guide rails 11 (hereinafter referred to as article conveyance area A, indicated by diagonal lines in FIG. 2). - Consists of a belt. Endless
The bell 1- is rotated in one direction by a driving source such as a morph (not shown) via a plurality of rollers 15, 1617, 18 so that the bottom of the article conveying area A is (1?1).

Further, the driving means 13 is provided with a plurality of protruding driving elements 13a spaced apart by a predetermined interval on the surface of the endless belt to engage with the lower end of the movable body 12, which will be described later.

As shown in the perspective view of FIG. 4, the movable body 12 includes a plate-shaped pressing section 121 disposed approximately along the transport cross section, and a plate-shaped pressing section 121 arranged along the transport path connected to the pressing section 121. 1, and rollers 19 provided at three locations at the connecting portion of the pressing portion 121 and the pressing rod 122, and at each end. Note that the pressing portion 121 is indicated by the arrow
The curved pieces 121a and 121b extend forward in the conveyance direction as shown by
rollers 19 are pivotally attached to the outer surfaces of the bent pieces 121a and 121b, respectively, and a bracket 121c having a protrusion 121d is rotatably attached to the other end of the pressing rod 122, Another roller 19 is provided on this bracket 12ic.

Next, in FIG. 5, to explain the arrangement state of the movable body 12, the movable body 12 is placed on the guide rail 11 on the outer circumferential side where the two rollers 19 on the press rod 122 side form a conveyance path. The remaining rollers 19 are attached to the guide rail 1 on the inner circumferential side.
1, and the pressing portion 121 is suspended on the conveyance path along the conveyance cross section. A drive member 1 of the drive means 13 disposed below the movable body 12
3a sequentially engages with the lower end of the pressing part 121, so that the pressing part 121 is moved at a constant interval in the article conveyance area A.

As shown in FIG. 6, the conveyance path 14 that has left the article conveyance class Jj)iA is such that, for example, in the turning region of the conveyance path, the movable body 12 is such that the press rod 122 is disposed only on the outer peripheral side of rotation. The adjacent movable body 12
The protrusions 121d abut each other to form a substantially triangular section with the inner circumferential side as the center of rotation, and rotation is preferably performed.

Also, even in a straight line area outside of this area, the movable body 12 forms a rectangular section approximately the length of the pressing rod 122 along the guide rail 11 by abutting the adjacent protrusions 121d. Move sequentially.

Next, the movement of the movable body 12 will be explained together with the method of transporting dust.

As shown in FIG. 7, the number of movable bodies 12 is set to be smaller than the number that can be accommodated in the entire conveyance path. As a result, the movement of the movable body outside the article transport area A repeats the moving state and the stopped state as appropriate.

That is, the dust 20 placed on the surface of the endless belt in the article conveyance area A is moved by the movement of the belt and the pressing force from the side by the pressing section 121. When the dust leaves the article transport area A, the dust is pushed out from the end of the endless belt by the movable part and discharged into the input port 3 in which a part of the transport path is cut out. Dust storage 2
The dust 20 discharged inside is pressed and compressed by the pressing plate 5. On the other hand, the movable body 12a, which has finished transporting the dust 20, is brought to a stopped state with the drive member 13a being disengaged. However, when the next movable body 12b is moved eventually, the movable body 12b is pushed forward by the suppressing force generated by the contact with this movable body 12b. Further, when the movable body 12b leaves the article transport area, its movement is similarly stopped. Then, when the next movable body 12c moves, it is similarly pushed forward and moves. By repeating this operation, the movable body 12 is sequentially pushed forward and circulates through the conveyance path by repeatedly moving and stopping. The movable body 12, which is empty after the dust 20 has been discharged, eventually reaches the turning area immediately before the article transport area A. In the dust collection vehicle 1 of this embodiment, this area is located closest to the ground surface, and the operator performs the work of throwing in the dust 20.

That is, if dust is thrown in while the movable body 12 is in a stopped state, it will eventually be pushed forward by contact with the rear movable body 12 and reach the starting point of the article transport area A. The movable body 12 that has reached the starting point to the article transport area moves to the endless
Movement is started by engagement of the drive element 13a arranged on the belt.

With the above configuration, the dust 20 is transported by the endless
Since this is carried out by pressing from the side by the belt and the pressing part 121, the conveyed article can be suitably moved even on a conveying path where the conveyed article rises rapidly as in this embodiment.

8 to 1O show other embodiments of the present invention, in which FIG. 8 is a plan view of the conveying device, FIG. 9 is a side view, and FIG.
0 shows a sectional view taken along line A-A in FIG. 8, respectively.

In the figure, the movable body 22 is formed approximately in the shape of a cage, and has a bottom surface 221 different from the conveyance path in a state where it is suspended from the guide rail 11, and articles, etc. are placed on the bottom surface 221 and moved. Therefore, unlike the previously described first embodiment in which a part of the driving means forms the movable body, the driving means does not necessarily have to be arranged below the movable body. That is, in this embodiment, a drive means 23 composed of a sprocket rotated by a drive device (motor) 24 and a drive chain that rotates while engaging with this sprocket is used to move the movable body between a part of the conveyance path. The leg portions 2 constitute a part of the movable body 22, and the drive levers 23a are arranged along the side surfaces and are provided at predetermined intervals on the drive chain 30.
22, the articles are sequentially conveyed at regular intervals in the article conveyance area.

In each of the embodiments described above, the movable body is conveyed in the article conveyance area A by a drive means provided over the entire article conveyance area A, and the pressing force of this drive means is movable outside the article conveyance area A. Although the configuration was such that the Vfi ring movement of the movable bodies is performed by pushing out due to contact between the bodies, each movable body is connected by a flexible member (for example, a chain, etc.), and the position immediately after the end of article conveyance area A is set. It can also be configured to be pulled by an appropriate drive means provided in the. Note that the movable body that has passed through the article transport area A is
For example, when the flexible member loosens and the movable bodies come into direct contact with each other, the movable bodies are sent to the front of the article conveyance area A by the pressing force and can circulate through the conveyance path.

In addition to the dust collection vehicle described in the first embodiment, the conveying device of the present invention can be applied to a conveying device for goods in logistics, a vehicle in a play facility, and the like. especially,
Since the number of movable bodies is set to be less than the number that can be stored in the entire conveyance path and the conveyance state and stop state can be selected as appropriate, the conveyance movement and the intermittent stop operation can be controlled by one continuously operated drive means. Cycle time can be selected arbitrarily. That is, by reducing the number of movable bodies in the conveyance path and setting a large pitch of the drive elements, the stopped state can be set for a long time. Note that the feed rate can be freely determined by the feed rate of the driving body.

(Effects of the Invention) As described above, in the conveyance device of the present invention, a plurality of movable bodies having pressing portions substantially along at least the forwarding cross section are movably provided on a loop-shaped track, and the article conveyance on the track is provided. The movable body is sequentially moved so that at least the pressing portions are separated at regular intervals by driving means provided along the areas sequentially press or pull the movable body between the article transport areas; In addition, in the track area other than the article transport area, the movable bodies are in contact with each other, so that the suppressing force of the driving means is transmitted and circulated on the track. Even on the conveyance path, irregularly shaped articles can be conveyed quickly and reliably. In addition, it is possible to change the conveyance path's steep angle, and it is possible to set a stop state during the conveyance process, so it can be used in cases where there are restrictions on the installation location of the conveyance device, such as in dust collection vehicles equipped with a dust inlet above the vehicle. It can also be applied if
It is possible to improve the safety and workability of dust collection work.

Further, according to the general conveyance device of the present invention, a relatively complicated conveyance path can be formed without adopting a configuration in which the conveyance system is divided into 1.1 parts and connected together as in the past. In addition, the 1/IQ iX speed is high and the object can be transported safely and accurately without applying any impact or the like to the object.
