Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a telescoping trolley chain conveyor, and more specifically, it can be extended outward to extend the conveyance distance of cargo, and when not in use. The present invention relates to a telescoping trolley chain conveyor that can be stored compactly, is relatively lightweight, such as rigid objects, and is suitable for transporting loads that need to be transported in large numbers per unit time.

[Prior art and problems to be solved by the invention]

Conventionally, there are a variety of luggage devices used to carry luggage from a luggage carrier into a warehouse, or conversely to load luggage from a warehouse into a luggage carrier, but from the viewpoint of storage performance, it is desirable It is best to have one that can be extended in its entire length when in use, and can be stored compactly when not in use.

Therefore, the applicant of the present invention filed a utility model registration application no.
The application was filed first under the No. The above-mentioned cargo handling device is formed by fitting and enclosing a plurality of sliders each consisting of a cylindrical body with an opening at the bottom in order from the largest one, and the inside of the slider is placed inside the innermost slider. It is constructed by disposing a hoisting means that can move freely in the other direction. This cargo handling device is constructed as described above, so if it is installed inside a cargo handling vehicle, each slider can be advanced to move the cargo loaded in the transportation vehicle outside the vehicle, such as a warehouse. It is possible to easily carry the goods inside the warehouse, and conversely, it is also possible to easily load the goods inside the warehouse into the transport vehicle. By retracting the slider when not in use, it can be stored compactly in the car.

Although it is effective as described above, in the case of the above-mentioned cargo handling device, only one hoisting means for transporting the cargo is disposed. This is because the hoisting means is configured to reciprocate inside the slider, and therefore only one piece of luggage can be transported during one reciprocation of the hoisting section.

If the above-mentioned cargo is heavy, there is a problem with the load capacity, so this may be acceptable, but the transport efficiency is not good for quickly transporting a large number of lightweight cargoes. By the way, a trolley chain conveyor has been put into practical use as a cargo handling device for quickly transporting a large number of lightweight cargoes. However, in the case of the above-mentioned trolley conveyor, the length of the rail on which the trolley runs is fixed, and the trolley conveyor is not structured so as to be extendable on a transport vehicle, for example.
Furthermore, in order to transport cargo one after another at high speed,
It is necessary to fasten the luggage. When latching the baggage, for example, if a string is attached to the baggage, it is relatively easy to do so, but if the baggage is not hung with a string, such as a cardboard box, it is difficult to hang the baggage on the trolley. .

The present invention was made in view of the above-mentioned times,
Its purpose is that when it is in use, it can be extended outward to increase its overall length, and when it is not in use, it can be stored compactly, and it is also relatively lightweight, allowing it to carry large amounts of luggage in a continuous manner. The trolley can be transported quickly, and it is easy to hang cargo with or without strings, resulting in good work efficiency.It also allows smooth extension and contraction of the entire length and endless movement of the trolley. Our objective is to provide a telescopic trolley chain conveyor that can be used.

[Technical means to solve problems]

The present invention has the following technical means to achieve the above object.

That is, to explain this based on the drawings corresponding to the embodiment, a plurality of sliders S ₁ , S ₂ , S ₃ each consisting of a cylindrical body with an open bottom surface are fitted and held in order of size, and A slider traveling means 9 configured to transmit the rotational torque of the motor 17 to the endless strip 6 and convert it into planar linear motion is disposed between each slider, and the slider traveling means 9 is arranged between each slider S ₁ , S ₂ , S ₃ can be expanded and contracted in both the one side 20 and the other side 21 along the longitudinal direction relative to each other, and the left and right sides facing each other with the lower opening of each slider inside. A traveling rail is formed on each of the sliders along the longitudinal direction of the slider, and at the other end of the innermost slider _S3 , traveling rail connecting members 18 and 19 each formed in a substantially L-shape are provided. The above running rails are connected to each other to form an endless running rail 22, and a plurality of trolleys 23 consisting of a top plate and running wheels rotatably supported below the top plate are freely runnable on the endless running rail 22. The trolleys are connected by a link mechanism 27, which is a telescopic member, to form a trolley chain 26, and the innermost slider
A trolley traveling means 28 configured to transmit the rotational torque of the motor to the endless strip body and convert it into planar linear motion is disposed on the ceiling surface of S ₃ , and the endless strip body 6 of this trolley traveling means 28 is The trolley 23 can be driven by bringing it into planar contact with the top plate 24 of the trolley 23, and each trolley 23 is made of a basket-shaped elastic body with an opening at the bottom, so that the cargo 32 can be accessed from above. This is a telescopic trolley chain conveyor which is provided with a baggage holding body 29 which can be covered and held.

[Effect]

Since the present invention has been achieved as described above,
By normally housing the slider S ₃ within the slider S ₂ and housing the slider S ₂ within the slider S ₁ , the whole can be housed compactly. During this storage, the trolleys are brought close to each other, and the entire trolley chain is stored in the slider _S3 in a contracted state.

When in use, by operating the slider traveling means, the surface friction between the endless strip and each slider causes slider _S2 to extend relative to slider _S1 , and slider _S3 to extend relative to slider _S2. The whole can be extended by extending it. The overall extension length can be arbitrarily determined by adjusting the extension length of each slider S ₂ and S ₃ . When the slider is extended in this manner, since the trolleys are connected by the telescopic member, the distance between the trolleys can be freely changed as the slider is extended. Therefore, the length of the trolley chain can also be freely changed depending on the length of the slider.

After the slider is extended to a desired length in this manner, the trolley traveling means is then operated to drive the trolley chain. The above-mentioned trolley chain is driven by the fact that, of the endlessly connected trolleys, the trolley positioned below the trolley drive means is caused to run by the surface friction contact of the endless strip of the trolley drive means. , the entire trolley chain is driven on an endless running rail.

When the trolley chain is driven in this manner, the load carriers disposed on each trolley successively travel above the load. Therefore, the luggage can be held by the luggage carrier by covering the luggage from above. The trolley carrying the luggage travels on the running rail and transports the luggage to a predetermined position. The load can be easily removed from the trolley by expanding the lower part of the load carrier. Since the trolley chain is formed in an endless shape, by simply rotating the trolley chain in one direction, it is possible to transport the load and at the same time return the empty load carrier to the place where the load is to be held, one after another. The cargo can be transported quickly.

In particular, when transporting a large number of items from one side to another, it is possible to gradually shorten the long total length or gradually lengthen the shortened total length while conveying, allowing for efficient transport according to the loading situation of the items. A short-distance moving point can be secured.

When the conveyance of the cargo is completed, the trolley traveling means is stopped and the slider traveling means is operated to house the slider _S3 in the slider _S2 and to house the slider _S2 in the slider _S1 . This allows the whole to be housed compactly.

〔Example〕

Next, preferred embodiments of the present invention will be described in detail.

In the figure, reference numeral 1 indicates the slider body, which is formed inside the slider S ₁ , which is a cylindrical body with an opening 2 formed on the bottom surface, in the same way as the slider S ₁ , and is also smaller than the slider S ₁ . At the same time _{, a slider S 3 formed} in the same way is fitted inside this slider S ₂ .
It is constructed by fitting together. On both sides of each slider S ₁ , S ₂ , S ₃ fitted in this way, facing each other with the opening 2 at the center, running rails 3 for supporting a trolley, which will be described later, are arranged along the longitudinal direction. It is formed. Above running rail 3
In this embodiment, before forming the sliders S ₁ , S ₂ , and S ₃ , both ends along the longitudinal direction are bent inward and upward.

The slider S ₂ fitted inside the slider S ₁ as described above is configured to be able to move freely relative to the slider S ₁ , and the slider S ₂ fitted inside the slider S 2 S ₃
is designed to be able to move freely relative to slider _S2 . That is, on the left and right sides 4 and 5 of the slider _S1 , an endless strip 6 is placed on the slider.
A slider traveling means 9 is disposed in contact with the walls 7 and 8 of _S2 , and the slider _S3
An endless strip 6 is disposed on the top surface 10 while being in contact with the inside of the top surface 11 of the slider _S2 . This embodiment shows an example in which two slider traveling means 9 are disposed on the left and right side surfaces 4 and 5 of the slider _S1 , and two on the upper surface 10 of the slider _S3 .

As shown in FIG. 6, the slider traveling means 9 has one wheel 13 rotatably disposed in a box-shaped casing 12 with one side open, with a part of the circumferential surface exposed from the opening. At the same time, the other wheel 14 is rotatably disposed at a predetermined distance from the wheel 13 and with a portion of its peripheral surface exposed from the opening surface. these wheels 1
Engagement teeth 15, 15 are formed on the circumferential surfaces of wheels 3 and 14, and engagement teeth 1 of each wheel are formed between each wheel.
An endless band-like body 6 is wound on a track and has meshing teeth 6a formed thereon for engaging with the teeth 5 and 15. The input shaft 16 for applying rotational force to one of the wheels 13 is connected to the output shaft of a geared motor 17.

This allows the geared motor 17 to
When rotated, the outer circumferential surface of the endless strip 6 runs in a straight line between one wheel 13 and the other wheel 14, so the slider S ₂ can run efficiently relative to the slider S ₁ . In addition, the slider _S3 can be moved efficiently relative to the slider _S2 .

Next, 18 and 19 are the innermost sliders
It is a traveling rail connecting member fixed to one side 20 end of S ₃ and the other side 21 end of _the outermost slider S ₁ , and has a substantially U-shape. One side 20 end of the formed running rails 3, 3 is connected in a curved shape, and the other side 21 end of the running rail 3, 3 formed in the slider _S1 is connected in a curved shape as well. be. In this way, one end of the running rails ₃ , 3 formed in the slider S 3 and the other end 21 of the running rails 3, 3 formed in the slider S ₁ are connected in a curved manner. Accordingly, an endless traveling rail 22 as shown in FIG. 3 can be formed.

Next, 23 is the endless running rail 22
A trolley that can be run on top of the top plate 2
A running wheel 25 is rotatably arranged on the lower side of the wheel 4. A plurality of these trolleys 23 are arranged on the endless traveling rail 22,
An endless trolley chain 26 is formed by connecting each trolley with an elastic member. The reason why the telescopic member is used to connect the trolley 23 is that the length of the endless running rail 22 changes as the sliders S ₂ and S ₃ move forward and backward, so the length of the trolley chain 26 is adjusted accordingly. This is because the total length must be changed. Although various types of extensible members can be considered, this embodiment shows an example in which a link mechanism 27 is used.

Trolley chain 2 formed in this way
6 is caused to run on the endless running rail 22 in one direction or the other direction by the trolley running means 28. The trolley traveling means 28 is formed in the same manner as the slider traveling means 9, and the endless strip 6 is connected to the top plate 2 of the trolley 23.
The slider 3 is disposed on the upper surface of the slider 3 so as to be in contact with the slider 4. The above-mentioned trolleys 23 are arranged at predetermined intervals, and by arranging four trolley running means 28 as shown by the one-dot chain line in FIG. 2
8 and the trolley 23 can be kept in contact with each other at all times, thereby allowing the trolley chain 26 to run smoothly at all times.

Next, 29 is a luggage carrier, and trolley 23
It is attached to an L-shaped shackle 30 overlaid from above, and has a basket shape with an opening 31 formed at the bottom, and is entirely made of an elastic material such as rubber. This baggage holding body 29 is arranged to hold and transport the baggage 32, and has an opening 3 formed at the bottom.
1 is used to wrap the baggage 32 by covering it from above.

The telescoping trolley chain constructed as described above can be installed and used in various locations, such as the platform of a cargo handling center, inside a warehouse, etc. The example in FIG. 8 shows a case where the baggage 32 is fixed to the ceiling of a canopy-equipped carrier 33 and carried into a warehouse 34. In addition, 35 in the figure is a slider
This is a support rod installed near one end of _S3 .

Next, the operation will be explained based on the above embodiment.

Since the telescoping trolley chain conveyor of the present invention is configured as described above, when not in use, the slider _S3 can be housed in the slider _S2 , and the slider _S2 can be housed in the slider _S1 . Therefore, the whole can be stored compactly. At this time, trolley chain 26
It has also shrunk into a compact size. That is,
This is because since the trolleys 23 are connected by the link mechanism 27, the distance between the trolleys 23 can be changed freely.

When using this, the slider traveling means 9 is driven. That is, when the geared motor 17 of the slider traveling means 9 is rotated, the input shaft 16 is rotated. As a result, one of the wheels 13 is rotated, so that the endless strip wound around the wheel 13 is made to travel. The endless strip 6
As mentioned above, one wheel 13 and the other wheel 1
Since it is wound between the wheels 13 and 14, it runs in a straight line between the wheels 13 on one side and the wheels 14 on the other side.
Engagement teeth 15 are formed on the circumferential surfaces of one wheel 13 and the other wheel 14 during this running, and engagement teeth 6a that mesh with the engagement teeth 15 are formed on the inner surface of the endless strip 6. Therefore, wheels 13,
There is no slippage between the belt 14 and the endless strip 6, and so-called timing synchronization can be achieved. When rotational motion is converted into linear motion in this way, the contact area with the other surface to be moved can be increased, and therefore the contact friction resistance can also be increased, making the output of the geared motor 17 more effective. It can be used for. Therefore, the slider _S2 , which is in contact with the endless strip 6 of the slider traveling means ₉ disposed on the slider S1, can be reliably moved as shown by the arrow 36 in FIG. The slider _S3 is moved by the slider traveling means 9 disposed on the slider _S3.
The vehicle can also be made to run reliably as shown by arrow 36.

When the sliders S ₂ and S ₃ travel as shown by the arrow 36 in this manner, the total length of the slider body 1 becomes longer. Therefore, the total length of the endless traveling rail 22 formed within the slider body 1 also becomes longer. For that purpose, endless running rail 22
The total length of the trolley chain 26 disposed above also increases as it is pulled by the endless traveling rail 22.

That is, by being pulled in this way, the link mechanism 27 connecting the trolleys 23 is extended, and the distance between the trolleys 23 becomes longer.

When extending the slider body 1, the length of the extension can be freely adjusted within the range of the maximum extension length by adjusting the length of the sliders S ₂ and S ₃ . I can do it.

After the slider main body 1 is extended in this manner and its tip end is advanced into the warehouse 34, a support rod 35 is preferably erected near the tip end as shown in FIG. As a result, even if a heavy object is transported, the tip part will not fall downward.

Next, the trolley traveling means 28 is caused to travel,
The trolley chain 26 is made to run. The trolley traveling means is configured similarly to the slider traveling means 9, and has an endless strip 6.
Since the top plate 24 of the trolley 23 is placed in contact with the trolley 23, the trolley 23 in contact with the endless strip 6 is made to travel. Since the trolleys 23 are arranged at predetermined intervals, regarding one trolley traveling means,
Immediately after running the trolley 23, it may become impossible to run the next trolley.
However, since a total of four trolley running means 28 are provided, only one of the other trolley running means 28 is provided.
The trolley is in contact with one, two, or in some cases three trolleys, and these trolley running means similarly cause the trolley 23 to run, so the trolley chain 26 as a whole is driven smoothly without any breaks. You will be forced to do so. After the trolley chain 26 is driven in this manner, the cargo 32 loaded in the canopy-equipped carrier 33 is caused to be held in the cargo holding body 29. The above-mentioned baggage holding body is 2
Using the opening 31 formed below the baggage 32 while expanding the baggage carrier 29,
Cover it from above. If you release your hand after covering it from above, the baggage holding body 29 will contract and tightly hold the baggage 32. The baggage 32 wrapped in this manner is carried into the warehouse 34. The baggage carrier 29 can be easily taken out by opening the lower opening 31 inside the warehouse. Since the baggage 32 can be held and transported in this way, even cardboard boxes or the like that are not hung with strings can be easily transported.

Since the baggage carrier 29 is attached to a shackle 30 superimposed from the trolley 23, it runs endlessly along an endless traveling rail.

Therefore, it is possible to run continuously between the place where the baggage 32 is held and the place where the baggage is taken out.
In other words, unlike cargo handling equipment that travels back and forth, there is no loss in waiting for empty items to come back.
Cargo handling work can be streamlined.

In particular, since the total length of the endless traveling rail 22 can be changed, for example, when the total length is extended to the maximum and cargo is loaded from inside a warehouse or from the back of a transport vehicle, the total length can be shortened according to the loading situation. I can do it. On the other hand, when carrying out cargo from the front, it can be extended to the back according to the carrying situation, which improves the work efficiency of loading and unloading.

When the conveyance work of the baggage 32 is completed, the operation of the trolley running means 28 is stopped to stop the running of the trolley chain 26, and at the same time, the slider running means 9 is operated to house the slider _S3 in the slider _S2 and move the slider S ₂ is accommodated within slider S ₁ . As a result, the slider main body 1 can be housed in the canopy-equipped carrier 33 in a compact manner.

In this embodiment, the sliders S ₂ and S ₃ extend in 20 directions on one side, that is, in the 36 directions indicated by arrows in FIG. 1, but the sliders S ₂ and S ₃ extend in 20 directions on the other side.
It can also extend in one direction. When extending in the other side 21 direction in this way, the traveling rail connecting member 18 fixed to the one side 20 end of the slider _S3
is fixed to the other side 21 end of the slider _S3 , and the travel rail connecting member 19, which is fixed to the other side 21 end of the slider _S1 , is fixed to one side end of the slider _S1 .

In order to easily change the extending direction of _the sliders S ₂ and _{S 3 ,} as shown in FIG. Traveling rail connecting member 18,1
If a recess 39 for the projection 37 is formed on the side surface of the travel rail connecting member 18, 19,
They can be easily fixed by simply fitting them into the holding pieces 38, 38.

In addition, in this embodiment, an example was shown in which the slider body 1 was directly fixed to the ceiling of the canopy-equipped carrier 33, but when it is fixed to the ceiling in this way, it is fixed via a vertical movement mechanism or a lateral movement mechanism. By doing so, transportation can be carried out more rationally.

Furthermore, the telescoping trolley chain conveyor of the present invention can be used by being installed inside a warehouse or on a self-propelled trolley.

〔Effect of the invention〕

Since the present invention consists of the technical means as described above,
When in use, the slider traveling means 9 is operated to cause the slider S ₂ to travel relative to the slider S ₁ and to cause the slider S ₃ to travel relative to the slider S ₂ , thereby causing the slider body 1 to travel.
In addition, when not in use, the slider S ₂ can be accommodated in the slider S ₁ without excess or deficiency, and the slider S ₃ can be accommodated in the slider S ₂ without excess or deficiency. By accommodating the baggage in a compact manner, the entire baggage can be stored compactly.Also, since an endless trolley chain 26 is disposed inside and is moved by the trolley running means 28, the baggage can be continuously stored. The baggage can be transported quickly, and the baggage can be hung on the trolley 23 by being held by the baggage carrier 29, which has a basket shape with an opening 31 formed at the bottom and has elasticity as a whole. Therefore, it is easy to attach and detach the load regardless of whether a string is attached or not, and the work efficiency is high. Furthermore, the slider traveling means 9 and the trolley traveling means 29 are controlled by the rotational torque applied to the input shaft. Since the traveling means is configured to convert the movement into planar linear motion, the friction with the contact surface of the moving object can be increased, and the sliders S ₂ and S ₃
It has various advantages such as providing a telescoping trolley chain conveyor that can smoothly run the trolley chain and the trolley chain.
