TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cargo handling device that performs unloading and loading as a truck bed or container.
[0002]
[Prior art]
Taking a truck bed as an example, as a method of unloading small non-lumped cargoes such as scrap iron and other chips, gravel and other granular materials, the bed 1 itself is inclined by the cylinder 2 as shown in FIG. As shown in FIG. 16, there is a so-called dumping method in which the feed plate 4 is moved up and down by a cylinder 3 and the feed plate 4 is moved backward by the cylinder 3, and the chips on the load bed 1 are pushed out by the feed plate 4. .
[0003]
Further, as shown in FIG. 17, the platform 5 includes a platform 5, a hydraulic device 6, a cylinder 7, an overbang 8, and a weighing device 9, and the platform 5 tilts the tipping wheel up to 55 degrees by driving the hydraulic device 6 and the cylinder 7. It is unloaded and is framed by shaped steel and steel plate, has sufficient breadth and strength for the unloading of chip vehicles, and has one end for supporting the chip vehicles when the platform 5 is inclined. A backstop 10 using a strong section steel is attached.
[0004]
In the conventional method shown in FIGS. 15 to 17 and the dumping method of the loading bed 1 shown in FIG. 15, it is required to provide a certain inclination angle or more in order to discharge all the chips of the loading bed 1 smoothly and completely. However, there is a limit in the cylinder 2, and when the carrier 1 tilts, the center of gravity is moved to an unstable state.
[0005]
In the case of the feed plate system shown in FIG. 16, since the feed plate 4 must be moved from one end of the carrier 1 to the other end, the stroke of the cylinder 3 is a problem. Impossible. Further, although there is no method for sequentially moving the cylinder 3 itself, the fixing method is complicated and the usability is troublesome.
[0006]
In addition, since the feed plate 4 has a force for pushing the chip backward, a strong thrust is required for the cylinder 3.
[0007]
In the method of inclining the entire chip car on the platform 5 shown in FIG. 17, the entire device becomes large-scale, and the unloading operation cannot be performed unless the device on the platform 5 is located. In addition, during the series of operations, if the next tipping vehicle enters with the overbang 8 opened, there is a risk of falling into the receiving bin, and also in the case where the ascending position of the backstop 10 is not appropriate. It falls and becomes a serious disaster.
[0008]
Therefore, the inventor of the present invention has previously described the unloading device for the truck bed of Japanese Patent No. 30625568 as a device that is simple and inexpensive and can be operated safely and efficiently with a small number of people. Filed and obtained patent right. As shown in FIGS. 18 to 26, a slide plate 15 having substantially the same width as the bottom plate 14 is placed on the bottom plate 14 of the loading platform of the truck 11, and the space between the back of the cabin 13 and the front end of the slide plate 15 is provided. A cylinder 16 was provided as a mechanism for moving the slide plate 15 back and forth.
[0009]
Further, on the slide plate 15, the side ends can be locked to the left and right loading plate side plates 17 of the loading platform 12, and at the time of locking, the edge is cut off from the sliding plate 15, and only the sliding plate 15 moves, and When stopped, a partition plate 18 is provided, which is coupled to the slide plate 15 by friction or the like and moves together with the slide plate 15. The partition plate 18 is made of a steel plate or the like, and has a bottom base 18 a having a certain width so as to stand on the slide plate 15.
[0010]
Assuming that the cargo A is on the loading platform 12 of the truck 11, the vehicle is stopped with the rear end positioned at the place where the bit 20 is located, and the rear end surface of the loading platform 12 is open.
[0011]
When the cylinder 16 is extended, the slide plate 15 moves from the cabin 13 side to the rear end, and the cargo A and the partition plate 18 on the slide plate 15 move accordingly. In this state, the partition plate 18 is not locked to the carrier side plate 17.
[0012]
As a result of the sliding of the slide plate 15, the rear end of the slide plate 15 projects above the bit 20 behind the loading platform 12 with the load A placed thereon.
[0013]
Next, the partition plate 18 is locked to the loading platform side plate 17 with a stopper pin or the like, and the cylinder 16 is reduced and the slide plate 15 is pulled toward the cabin 13 as it is, so that the front end of the cargo A is fixed by the partition plate 18. Since the slide plate 15 is not provided at the rear of the loading platform 12 and does not move, the slide plate 15 is lost, so that it falls into the bit 20.
[0014]
When the cargo A is dropped in this way, the partition plate 18 is locked to the carrier side plate 17, the cylinder 16 is extended again and the slide plate 15 is pushed backward, and thereafter (1) the slide plate 15 is pushed out. The procedure of (2) locking the partition plate 18, (3) retracting the slide plate 15, (4) dropping the load A, and (5) releasing the lock of the partition plate 18 is repeated to bit all the loads A. Drop into 20. Thereafter, in order to prepare for the reloading, the partition plate 18 is moved to the front portion of the slide plate 15 on the cabin 13 side.
[0015]
[Problems to be solved by the invention]
In the unloading device for a truck bed disclosed in Japanese Patent No. 30625568, frictional resistance due to a load of a load or the frictional resistance between a slide plate and a bottom plate is added to a slide plate, and it is difficult to obtain a smooth movement. Large ones are required. In particular, the slide plate is desirably made of a steel plate or the like, but in that case, the weight of the slide plate itself is added, and the load on the cylinder increases.
[0016]
An object of the present invention is to solve the disadvantages of the conventional example and improve the unloading device of the truck bed of Japanese Patent No. 3062568. As a result, the device itself is simple and inexpensive, and can be safely operated with a small number of people. Another object of the present invention is to provide a cargo handling device such as a truck bed capable of realizing a more inexpensive device that can reduce the size of the drive mechanism and cause less trouble because it can work efficiently, reduce frictional resistance and reduce energy loss. .
[0017]
[Means for Solving the Problems]
In order to achieve the above object, the present invention firstly provides a left and right side plate with respect to a fixedly provided bottom plate so as to be able to move back and forth by a driving mechanism such as a cylinder, and locks the side plate with the bottom plate. It is possible to provide a partition wall between the left and right side plates, which is movable together when locked and moves only the side plate when unlocked. Secondly, a side plate side rack rail is provided. Third, providing a cam provided with a claw that is locked only in one direction in a continuous concave portion of the rail. Third, providing each of the left and right cams with a locking direction opposite to a rack rail. In the fourth aspect, a telescopic cylinder is provided on the side plate and the partition, and the partition is fixed to the side plate by fixing the telescopic cylinder.
[0018]
Fifth, as a platform, left and right side plates are provided so as to be movable back and forth by a driving mechanism such as a cylinder with respect to a fixed bottom plate. Sometimes, a partition body in which only the side plate is stopped and moved is disposed between the left and right side plates, and a telescopic cylinder is provided on the partition body with one end fixed to the bottom plate side as a moving mechanism of the partition body. The point is that the carrier is a container.
[0019]
According to the first aspect of the present invention, first, a description will be given of a case where unloading is performed from the back of the loading platform. The loading of granular materials, chips and the like is placed on a fixed bottom plate, and the partition body is connected to the side plate. Stopping, pushing out the side plate and the partition body pushes the load backward by the partition body, and the load at the rear of the loading platform falls off the bottom plate.
[0020]
The lock between the partition and the side plate is released, only the side plate is returned to its original state, and the partition is locked to the side plate again, and the same operation is repeated.
[0021]
When all of the cargo has been unloaded in this manner, the back-and-forth movement of the side plate and the separation of the bulkhead from the side plate are repeated in the reverse operation to sequentially send the bulkhead to the front of the loading platform to prepare for the next load.
[0022]
Even if a cylinder is used for the back and forth movement of the side plate, the stroke may be small, and the loading of granular materials, chips, etc. is pushed out from the front side to the rear side by the partition wall, but the side plate is also on the front side This cargo does not swell as it moves backwards from.
[0023]
According to the second aspect of the present invention, the pawl of the cam is engaged with the continuous recess of the rack rail so as to be locked in only one direction, and the side plate moves in one direction, for example, in the direction of the load discharge port. In this case, the rack rail and the pawl of the cam are locked, and the partition wall is fixed to the side plate, which pushes the load as a pushing wall in the discharge direction.
[0024]
Next, when the side plate moves in the other direction, for example, in the direction of the unloading outlet, the rack rail and the claw of the rotating body slide without being locked, and as a result, only the side plate moves. Hereinafter, by repeating this, the partition body and the load can be moved to the load discharge port, and the load can be discharged to the outside.
[0025]
According to the third aspect of the present invention, the pawls are provided with the cams on the left and right opposite to the locking direction with respect to the rack rail, so that the partition wall and the load are moved to the load discharge port as described above, In addition to being able to discharge the load to the outside, the other claws are engaged with the rack rails to move the bulkhead to the back of the loading platform, that is, to return the bulkhead that has moved to the load discharge port to its original position. Similarly, the load and the partition are moved together with the side plate, and then the rack rail and the claw of the cam are locked, the partition is fixed, and only the side plate moves in the direction of the load discharge port. By repeating, the partition can be moved to the back of the carrier.
[0026]
According to the present invention, a telescopic cylinder is used in place of the engagement between the rack rail and the pawl of the cam. When the partition wall and the side plate are locked, the telescopic cylinder is not used. The telescopic cylinder was free and only the side plate was moved to make the telescopic cylinder fixed and the partition wall and the side plate to be in the unlocked state.
[0027]
According to the fifth aspect of the present invention, first, a description will be given of a case where the unloading is performed from the back of the loading platform. The cargo is placed on a fixed bottom plate, and the movement of the partition body is moved by the telescopic cylinder to the movement of the side plate. By pushing out the side plate and the partition body in synchronization, the load is pushed backward by the partition body, and the load at the rear of the loading platform falls off the bottom plate and falls.
[0028]
Next, the synchronization between the partition and the side plate is released, the telescopic cylinder is stopped, the partition is not moved, only the side plate is returned, and the synchronous movement of the partition and the side plate is repeated again.
[0029]
When all of the cargo has been unloaded in this manner, the bulkheads are sequentially sent to the front of the loading platform by repeating the forward and backward movements of the side plates and the synchronous movement and the asynchronous movement of the bulkheads in the reverse operation to prepare for the next load.
[0030]
According to the present invention as set forth in claim 6, container transportation has increased in recent years in terms of reduction of transportation cost and packaging cost, shortening of transportation period, prevention of cargo pain, etc., but without major remodeling of the container, In addition, it is possible to mechanize the unloading and unloading of loads stacked without gaps in the container without any pallets in the container without installing large-scale equipment outside or in the container, eliminating the heavy work of unloading manually. Accordingly, it is possible to cope with the aging of the worker who unloads the container and the improvement of work efficiency.
