[0007]
[Action]
The material receiving container transport device according to the present invention is characterized in that the container is mainly vertical and has at least two side portions, and at least one protrusion for engaging two load supports on each outer surface thereof. Have Here, at least one load arm of the lifting device corresponds to each side portion, the load support is arranged at the lower end of the swivel arm which extends mainly vertically, and the horizontal position and the projection by the projection The other end of the swivel arm is connected to the load arm so that it can swivel about the shaft so that the load support can move between the lower positions.
[0008]
That is, the problem of the present invention is that the load support can be swung from the first position in the vertical direction within the cross-sectional area of the protrusion to the second position outside this cross-sectional area via the protrusion by the downward movement of the load arm. The opening / closing component is arranged on the swivel arm above the load support, and the upward movement of the load arm allows the opening / closing component to cover the load support via the protrusion and be guided around the protrusion. Solved.
[0009]
With the method according to the invention, when the load arm is lowered, the load support is pushed aside through the protrusion and can move around the protrusion. When the load support passes through the projection by the downward movement of the load arm, the load support is reversed downward again to the vertical cross-sectional area of the projection by the action of gravity, so that the load support is now raised by the load arm. Then, the lower part of the protrusion can be grasped and each container can be received for transportation.
[0010]
If such an operative connection between the load support and the container is released again after the container has been lowered, for example, the load arm moves further downward, so that the opening and closing component moves the load support through the projection. It becomes a covering position. If the load arm rises again, the projection pushes the opening / closing component, and this pushes the swivel arm and the load support device placed on the swivel arm, so the load support device guides the projection by the upward movement. This removes it from the protrusion and the container.
[0011]
The mechanism obviously operates automatically in the field, so that no adjustment means depending on the controlled supply of external energy is required for the movement of the load support. Furthermore, the apparatus of the present invention is structurally simple in view of its principle, and has few moving parts, so that it is difficult to be damaged and can ensure operational safety.
[0012]
With regard to the possibility of movement of the load support, this movement is mainly in the vertical direction, but it is also arranged in a direction parallel to the side part, depending on the spatial situation in the individual case, especially the space available for the movement of the load support be able to. In this case, in the case of a load support device that can move vertically to the side surface portion, the load support device corresponding to each side surface portion is gathered into a load support device of a considerable width, and this does not impair the overturning safety of the container. .
[0013]
Since each side portion has two protrusions juxtaposed in the horizontal direction, a unique protrusion can be used for each load support, especially when the container is accelerated or decelerated in a horizontal motion by a lift device. It is appropriate because high container rollover safety is obtained.
[0014]
In all cases, it is generally appropriate to arrange the protrusions at the same height so that a symmetrical structure is possible with the device of the invention.
[0015]
The load support is moved upwards so that the load support can be easily pushed through the protrusions and guided around the protrusions with the simultaneous substantial pivoting movement of the swivel arm in the downward movement of the load arm. It is advantageous to couple with the swivel arm via an inclined surface in a corresponding projection that is inclined. Next, in the downward movement of the load arm, this inclined surface hits the protrusion, slides at the corresponding corner of the protrusion, the load support is connected to the end of the inclined surface, and this time, after considerable movement of the swivel arm, The load support is outside the vertical cross-sectional area of the protrusion. In this case, obviously, the inclined surface is given an inclination angle which prevents a high frictional force or a danger of not moving due to the movement.
[0016]
Furthermore, the open / close component is supported by the swing arm so as to be able to rotate from the basic position against the reset force around the horizontal axis, and the open / close component is moved downward from the basic position via the protrusion in the subsequent downward movement of the load arm. And can be rotated in a direction opposite to the position covering the load support through the projection by the next upward movement of the load arm.
[0017]
That is, the opening / closing component, which may be mainly in the form of a handle or an opening / closing cam, is held at the neutral basic position by the resetting force of the swing arm. If the opening / closing part hits the protrusion from above with a considerable downward movement of the load arm, the opening / closing part pivots against the reset force, so it can slide over the protrusion and then reset. By force, it is swung again to the basic position, so that the opening / closing component is now under the projection. If the load arm rises next time, the opening / closing component hits the protrusion from below, and in this direction, the opening / closing component slides in the opposite direction and is swung to a position guided around the protrusion. A stationary load support is guided around the protrusions outside.
[0018]
Here, in order to ensure the position mentioned last so that a load support tool may not collide with a protrusion, the reset force which acts on an opening-and-closing component can be made into an appropriate magnitude | size. However, when the opening / closing component is in contact with the load support at the position where it covers the load support, that is, when the opening / closing component hardly protrudes, it is sized so as to cover at least the upper corner of the load support in the direction of the protrusion. It is advantageous to have
[0019]
If the possibility of moving the load support in the direction perpendicular to the side surface portion of the container when unlocking and unlocking the protrusion is used, the rotation axis of the swivel arm and the opening / closing component is further reduced relative to the side surface portion. When positioned parallel to each other, it is appropriate to dispose load supporting tools corresponding to the respective side surface portions on a common swivel arm and to arrange opening / closing components corresponding to the load supporting tools on a common shaft. This gives a particularly simple structure. This also allows the shaft and associated opening / closing component to be operated in an appropriate state by an additional opening / closing component, for example, an opening / closing component disposed between the protrusions. Because it does not pivot aside through the protrusion, some margin will be gained regarding the structural shape of this first opening / closing component. However, for the additional opening and closing parts, this method can only be used in special cases because an additional opening and closing cam is required on each side of the container.
[0020]
The reset force for the switchgear is formed by at least an indirect spring acting on the switchgear and supported by a swivel arm, where the system consisting of the switchgear and spring is balanced at the basic position of the switchgear. Is in a state. Therefore, the spring can act in a considerable state on the shaft that supports the opening / closing component.
[0021]
The protrusions on the side portions have a hollow section that is open in the vertical direction and can be provided with a cam that protrudes upward at the end of the free load-bearing tool. Next, since the load supporting device is engaged with the hollow portion of the protrusion by the rising of the container, the container is held by the cam so as not to be detached from the load supporting device.
[0022]
With respect to lift devices, these devices have a wrist girder that can be moved upward, extending between the side portions mainly over the length of the container, corresponding to the side portions and of the corresponding side portions from the lift girder. A load arm extending downward to a vertical plane can be secured to the end of the lift beam. This structural shape is suitable, for example, for receiving a box-like container, in particular for receiving a long pallet with a projection at the front.
[0023]
However, if there are a number of containers in parallel with each other and optionally in parallel with each other with respect to the side parts, e.g. a row of yokes that commonly accept a bundle of rod-shaped material, the lifting device is Appropriately extending over the width of all containers and having a wrist girder that can be moved upward, on its side, corresponding to the side part of the container and extending downward from the lift girder to a vertical plane in the corresponding projection The load arm is fixed.
[0024]
The previous discussion of the subject of the invention always presupposed only the handling of containers or rows of containers arranged in a horizontal plane. However, there is an application example in which a large number of similar containers are stacked, for example, there are cases where two or three containers are desired to be lifted or transported simultaneously. In this case, the load arm above the load support can have a free length to accommodate the height of the at least two stacked containers. This allows the load arm to move down until the load support can pass through the protrusions of the two stacked containers, for example, grab the protrusions of the lower container and raise both containers. .
[0025]
However, in connection therewith, it is possible to have a number of swivel arms with load supports and opening and closing components for the protrusions of the container in which the load supports are stacked. This somewhat complicated method is recommended here, especially when large and heavy containers must be handled, since the weight can be distributed over a number of load supports. Here, in order to prevent inability to measure due to dimensional tolerances related to uniform load distribution, the distance between the load supports arranged above and below the load arm is at least slightly greater than the distance between the protrusions of the stacked containers. Larger is ultimately advantageous.
[0026]
【The invention's effect】
As a result, it is possible to provide a transport device that does not require supply of external energy and does not require adjustment means that is driven thereby, and can operate the load support on site.
[0027]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a stack of stacked containers in the shape of a long cassette 1 for receiving a material, for example a metal rod-like material. The cassette 1 has two opposite side portions having protrusions 3 protruding horizontally on the front wall, and can be carried by holding the protrusions 3.
[0028]
For this reason, for example, a lift beam 5 fixed to a lift device (not shown) via a rope 4 is used. A load arm 6 extends vertically downward from the end of the lift beam 5. The load arm 6 supports a hook-shaped load support tool 8 at its end via a swivel arm 7. The load support 8 can be engaged with the protrusion 3. As can be seen from FIG. 1, the load arm 6 has a long shape and can extend over a number of pallets in the vertical direction, so that a number of cassettes stacked in a stack via the projections of the bottom cassette. Even sediments can be raised and transported.
[0029]
In order to describe the load support in detail, FIG. 2 (a) partially shows the region of FIG. 1 as an enlarged view, and FIG. 2 (b) shows a front view of the object of FIG. 2 (a). As can be seen here, the side portion 2 extends in a sword shape above the height of the pallet 1 and ends at the lower corner 9 on the lower corner 10 of the cassette 1 on the other side as well. Are fixed in a shape-stopped state so that they do not deviate from each other. Further, as shown in FIGS. 2 (a) and 2 (b), the protrusion 3 forms a hollow cross section that is open in the vertical direction, and the hook-shaped load support 8 is similarly engaged in a shape-stopped state. ing.
[0030]
As can be seen from FIGS. 2 (a) and 2 (b) together with the enlarged partial views of FIGS. 3 (a) and 3 (b), the load support 8 is at the lower end of the swivel arm 7, where The swivel arm 7 is pivotally supported by the load arm 6 via the shaft 11 and hangs vertically from the load arm 6 so that the load support 8 is in the vertical cross-sectional area on the protrusion 3.
[0031]
In the swivel arm 7, a pair of handle-like opening / closing components 13 are supported on the load support 8 via a shaft 12 parallel to the shaft 11 so as to be rotatable. Here, one load is applied to each opening / closing component 13. The support 8 corresponds. Normally, the opening / closing component 13 is in a basic position which can be seen from FIGS. In the basic position, the open / close component 13 is held by a reset force in the form of a spring 14. The spring 14 is supported on the pivot arm 7 at 15 and meshes with the shaft 12 at 16. Here, at the basic position, the pivot position 16 is the surface area closest to the shaft support 15.
[0032]
As shown in FIGS. 2 and 3, each side portion 2 of the cassette 1 has two protrusions 3 spaced from each other so that the cassette 1 can be received without being overturned. One load support 8 corresponds to each of these protrusions. Here, the swivel arm 7 has an inclined surface 17 extending horizontally at the lower end, from which the load support 8 protrudes upward in the direction of the opening / closing component 13 and corresponds to the side portion 2. 8 is attached to a common swivel arm 7.
[0033]
Furthermore, the load arm 6 has an inclined surface 18 facing forward from the side surface portion 2 at its lower end. Because of the inclined surface 18, the load arm 6 can be easily arranged along the side surface portion 2 in cooperation with the sword-shaped extension of the side surface portion 2.
[0034]
The opening / closing component 13 touches the load support 8 in the direction described below in the direction from the top toward the load support 8 against the action of the reset force of the spring 14, so that it is covered from above. Until then, the opening / closing component 13 extends mainly in the direction of the load arm 6 from the shaft 12 having a gap as large as possible with respect to the load arm 6. In this case, the upper corner 19 of the opening / closing component 13 further forms an inclined surface directed forward from the load support 8 and the load arm 6 and gradually upward. The purpose will likewise become clear from the following specification which now describes the functional scheme of the device with reference to FIGS.
As shown in FIGS. 4A and 4B, the load arm 6 extends downward. Here, since the inclined surface 17 that supports the load support tool 8 hits the protrusion 3 from above and is slid along the protrusion 3, the load support tool 8 moves the swing arm 7 around the swing point 11 of the load arm 6 to the pallet 1. It is made to turn ahead from the side part 2 of this. As a result, the load support 8 can move around the protrusion 3 outside, and the load support 8 reaches the lower part of the protrusion 3 as shown in FIGS. 5 (A) and 5 (B). Here, since the load support 8 is disengaged from the protrusion 3, the swing arm 7 is again swung back to the first vertically lowered position, where the load support 8 is at the bottom of the protrusion 3.
[0035]
This time, if the load arm 6 is moved upward by the method shown in FIGS. 6 (a) and 6 (b), the load support 8 will enter the hollow cross section of the protrusion 3 that opens vertically from the bottom. Thus, the corresponding cassette 1 can be raised by raising the load beam 5 by the lift device.
[0036]
When the locked state is released again, the load arm 8 is newly moved further downward by the method that can be seen from FIGS. Here, the opening / closing component 13 pivots forward from its basic position against the reset action of the spring 14 around its axis indicated by the shaft 12 via the projection 3, so that the opening / closing component 13 protrudes in a considerable state. Pass 3
[0037]
If the opening / closing component 13 passes through the protrusion 3 by the downward movement, the opening / closing component 13 is returned to its basic position again by the action of the spring 14 and stopped in the manner known from FIG. This time, when the load arm 6 is moved upward again in the manner shown in FIG. 10, the opening / closing component 13 hits the projection 3 from below, and the free end of the spring 14 is in the direction of the load support 8. It turns in the opposite direction against the reset force, and the opening / closing component 13 finally comes into contact with the load support 8 in a manner that can be determined from FIGS. 11 (a) and 11 (b). Here, the corner 19 of the opening / closing component 13 forms an inclination that is continuously upward from the load support 8 and the load arm 6. This inclination is a subsequent upward movement of the load arm 6 and slides along the lower corner of the protrusion 3, whereby the swivel arm 7 and the load support 8 are swung forward from the load arm 6. The load support 8 can be moved around the protrusion 3 outside. This process is shown little by little in FIGS.
[0038]
Then, in a non-illustrated course after the above movement, the load arm 6 disengages upward from the cassette 1 so that the cassette is lowered to the desired position. That is, as can be seen, in the illustrated apparatus, the container can be received, transported, and lowered again by a simple traveling motion of the lift device without the need for adjusting external energy. In this case, a number of stacked containers can be transported simultaneously by the method shown in FIG.
[0039]
In the illustrated embodiment, the load support can pivot in a direction perpendicular to the side portion 2 and can move around the protrusion. Obviously, the same result is obtained even if the load support moves parallel to the side portion 2. For this reason, however, each load support usually requires a unique swivel arm fitted with one open / close component.
