Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The present invention is a freight vehicle in which a conveyor having a partition plate that divides the cargo storage compartment into the front and rear sides is mounted on the floor of the cargo storage compartment. This invention relates to a load transfer device.

(Prior Art) In general, this type of load transfer device is a conveyor that can move forward and backward so as to cover almost the entire bottom plate of the cargo storage room, as disclosed in, for example, Japanese Utility Model Application Publication No. 133616/1983. A door for loading and unloading cargo into and out of this storage chamber is formed near both ends of the conveyor, and a partition plate for partitioning the storage chamber is installed on the conveyor, and a partition plate is installed around the periphery of this partition plate to maintain airtightness. Some products are equipped with a packing system, and for example, in collection and delivery operations, delivery packages are loaded from the rear opening behind the partition plate while being transferred to the front side by a conveyor, and then the packages are transferred to the rear side by the conveyor and unloaded one after another. At the same time, empty boxes and collected cargo are loaded from the front opening into the storage chamber in front of the partition plate. In this case, the storage room is divided into front and rear sides by moving the partition plate, and the front side is loaded with empty boxes that are no longer needed and the items that have been delivered, and the rear side is loaded with items to be delivered only. This completely eliminates the need for transshipment work to organize cargo during delivery, which was previously considered indispensable.

(Problem to be solved by the invention) In the conventional example, packing is arranged around the partition plate, and the partition plate seals and partitions the front side and the rear side of the storage chamber. cannot be removed from the conveyor. Therefore,
When the collection and delivery work is completed and empty boxes and collected cargo are loaded on the front side of the partition plate, the partition plate is located at the rear end of the storage room and blocks the rear opening, so the front side of the partition plate is Luggage must be unloaded through the front door opening on the side of the truck. However, due to the structure of a freight vehicle, the rear opening is perpendicular to the direction of conveyor transport, so while it is possible to efficiently unload cargo transferred by the conveyor, the opening of the front door on the side is Because it is parallel to the direction, cargo near the opening can be easily unloaded, but cargo inside the storage chamber must be moved by a worker by entering the storage chamber, and even though there is a conveyor,
There was a problem that the unloading process was inefficient. Furthermore, when unloading this cargo using a forklift or the like, the front opening is narrow, making it difficult to operate.

The present invention was developed based on the above-mentioned problem, and allows even a single worker to easily remove the partition plate located at the rear end from the conveyor to open the rear opening, and allows the cargo loaded on the front side of the partition plate to be removed. It is an object of the present invention to provide a load transfer device for a freight vehicle that can be unloaded from the rear opening and can simplify and streamline collection and delivery operations.

[Structure of the invention] (Means for solving the problem) The present invention removably attaches a partition plate on a conveyor that divides a baggage storage chamber into a front side and a rear side. One end of the partition plate is rotatably pivoted to the upper end or side end of a rear opening provided on the rear surface of the storage chamber.

(Function) When the partition plate is located at the rear end of the conveyor, the partition plate is removed from the conveyor, and the partition plate is pivoted to the upper end or side end of the rear opening in the vicinity of the partition plate, and the partition plate is not pivoted. By rotating the side, the rear opening that was closed by the partition plate is opened, and it becomes possible to unload the baggage from the rear opening.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

In FIG. 2, an endless conveyor 4 and a conveyor drive device (not shown) are disposed on a floor 2 of a cargo storage compartment 1 of a truck so that cargo 9 can be transferred in the front and rear directions. A partition plate 5 is mounted on the conveyor 4 so as to divide the baggage storage chamber 1 into front and rear sides, and the lower end of the partition plate 5 is removable from the conveyor 4 by a detachable mechanism 8. . A side opening 6 is formed on the side surface in front of the center of the baggage storage chamber 1, and the baggage 9a on the front side of the partition plate 5 in the baggage storage chamber 1 is unloaded or loaded through the baggage loading/unloading opening/closing door 7. The rear opening 3 of the luggage storage compartment 1 is used for loading and unloading luggage in the luggage storage compartment 1. The upper end of the partition plate 5 is pivotally attached to the upper end of the rear opening 3 when the partition plate 5 is located at the rearmost part of the conveyor 4 in the vicinity, and the non-axis attached side is configured to be able to rotate upward. has been done.

The operation of the present invention configured as above will be described in detail below.

For example, in a collection/delivery business, the delivery baggage 9 is loaded on the conveyor 4 from the rear opening 3 to the rear of the partition plate 5 as shown in FIG. 1A, and the parcel 9 is transferred by the conveyor 4 as shown in FIG. 1B. At the same time, the collected cargo 9a such as empty boxes is loaded in front of the partition plate 5 through the side opening 6, and the cargo platform is fully loaded with cargo 9a as shown in Fig. 1C before returning. do. In this case, the partition plate 5 is located at the rearmost part of the baggage storage chamber 1 and closes the rear opening 3, and after that, the partition plate 5 is removed from the conveyor 4 by the detachment mechanism 8 as shown in FIG. 1D. Then, the upper part of the partition plate 5 is slightly tilted rearward, and its upper end is pivoted 10 to the upper end of the rear opening 3 in the vicinity. Next, the non-axis mounting side of the lower end of the partition plate 5 is rotated upward and flipped up to open the rear opening 3 that was previously closed by the partition plate 5. In this case, since the partition plate 5 is heavy, it is quite difficult for one operator to lower the partition plate 5 that has been detached from the conveyor 4 from the baggage storage chamber 1 to the ground, or to place it on the baggage storage chamber 1. Even if separated, the partition plate 5 is still connected to the conveyor 4.
The standing partition plate 5 is tilted a little, its upper end is pivoted to the upper end of the rear opening 3 nearby, and the lower end of the non- pivoted side is flipped upward to reduce the weight. It is easy to operate because it significantly reduces the burden and can be easily performed by a single worker. Furthermore, since the rear opening 3 is perpendicular to the moving direction of the conveyor 4, it is possible to unload the baggage 9a along the rear opening 3, move the conveyor 4 rearward, and unload the next baggage 9a. , it is possible to unload all the luggage 9a inside the luggage storage chamber 1 while remaining in the rear opening 3 using the conveyor 4,
The work of collecting the cargo 9a can be performed labor-savingly and efficiently. Furthermore, since the rear opening 3 is open, the collected cargo 9a can be lowered using a forklift or the like. After unloading the baggage 9a, the partition plate 5 is reinstalled on the conveyor 4 as shown in FIG. 1E, and the conveyor 4 is rotated in the reverse direction to return the partition plate 5 to the front as shown in FIG. It is something to do. The conveyor 4 may be a belt or a slat, and the side opening 6 is preferably located at the front or center of the baggage storage chamber 1.

However, the load is not limited to the side opening 6, but may also be loaded by a shooter from the top opening (not shown).
Alternatively, the load may be input from the driver's cab through a front opening (not shown) that communicates with the driver's cab.
The attachment/detachment mechanism 8 may be a bolt, nut, or rod.
It is preferable to fix the partition plate 5 with pins or the like. Also, instead of rotatably attaching the partition plate 5 to the upper part of the rear opening 3 using a pin or the like as shown in FIG. The side end portions may be pivoted 10 and rotated in the lateral direction.

If there is no attachment/detachment mechanism 8 as described above, the rear opening 3 will not be completely opened unless the detached heavy and large partition plate is removed from the loading platform, and such work will require two to three workers. It becomes necessary. However, if the partition plate 5 is pivoted and flipped upward when it is detached as in the present invention, even one operator can easily open the rear opening 3. In addition, when installing the partition plate 5 on the conveyor 4, the work is easy because the partition plate 5 can be mounted on the conveyor 4 with the partition plate 5 upright as it is attached to the upper end of the rear opening 3 near the partition plate 10. becomes.

In addition, as shown in FIG. 3, the conveyor 4 and the partition plate 5 are divided into two parts, for example, and the collected cargo 9a is placed only on the conveyor 4a on the side opening 6 side.
It is also possible to remove only the partition plate 5a standing upright from the rear opening 3 and to unload the collected cargo 9a from the rear opening 3.

Furthermore, if a lift device (not shown) is installed on the rear surface, the load can be automatically transferred to the lift device by a conveyor and automatically lowered by the lift device, which is even more effective.

[Effects of the invention] As described in detail above, according to the invention, a conveyor that can move forward and backward is installed on the floor of a luggage storage room in which an opening/closing door for loading and unloading luggage is formed at least on the front side, and the luggage storage compartment is placed on this conveyor. In a cargo transport device for a freight vehicle equipped with a partition plate that divides a room into a front side and a rear side, the partition plate is removably mounted on the conveyor, and the baggage storage room near the rearmost part of the conveyor is removably mounted. One end of the partition plate detached from the conveyor is rotatably attached to the upper end or side end of the rear opening provided on the rear surface, which reduces the weight burden when opening the rear opening. It has been significantly reduced, and even a single operator (operator) can easily remove the partition plate located at the rear end of the conveyor from the conveyor, pivot it to one end of the rear opening near the conveyor, and open it. Loaded cargo can now be transferred to the rear opening of the loading platform using a conveyor and unloaded, making it possible to save labor and improve efficiency in collection and delivery operations, and to make effective use of storage space on the loading platform. Its practical effects are significant.
