Description

  The present invention relates to a container lifting / tilting device applicable to a sorting machine that loads a sorting object from above. More specifically, it is mounted on or in contact with the sorting machine, and the container containing the objects to be sorted is placed and moved laterally along the sorting machine, so that the height of the input port above the sorting machine is increased. This is an apparatus that lifts the container and tilts the container at a predetermined angle at the position of the insertion port to facilitate the input of the sorting target object to the sorting machine. Further, the hook according to the present invention detachably connects a hanging cable such as a belt and a handle of the container when the container is suspended by a crane and placed on the container lifting / tilting device, and the container having a large weight is provided. Can be easily and safely handled.

In harvesting and shipping of agricultural products such as fruits, sorting work is performed to make the sizes uniform, and various sorters are used. For example, FIG. 1 is a photograph of a plum fruit sorting operation. The photo sorter uses a method in which plum nuts are flown over a slope on which a rotary drum with a number of holes for each standard size is arranged. Plum nuts come in various sizes in resin containers that can be seen from the front of the photo and are transported to the sorting yard, so lift the container to the height of the sorting machine's slope and tilt it to remove the plum nuts inside the slope. It is necessary to put it at the top. In the case of plum seeds, since the weight of a full container is generally about 25 kg, the work of lifting and tilting the container is a heavy labor, and there is a problem of worker fatigue and back pain.

If a sorting hoist-type crane is installed at the sorting site, the problem of lifting the container will be solved.However, it is necessary to suspend the container stably and tilt it on the sorting machine. The problem is how to fix the hanging cable to the container. Resin containers commonly used for agricultural products, etc., have rectangular holes on the left and right sides of the box as a handle, and hook the hooks provided at both ends of the forked cable split into the handle. It is often suspended. However, a container suspended at two points can be easily tilted, but is unstable, and therefore has a high risk. Increasing the number of pairs of belts and hooks to be hooked on the handle improves stability, but also makes it more difficult to tilt, and also makes attachment and detachment to the handle cumbersome.

On the other hand, as a mechanism for tilting a container such as a heavy container, various prior arts have been proposed in the field of distribution and manufacturing facilities. For example, the article take-out device disclosed in Patent Literature 1 tilts a tilting table on which a container is placed with a tilting cylinder. In addition, the tilting device disclosed in Patent Literature 2 lifts and moves a bucket via a hanging tool by a hoisting device of a traveling vehicle mounted on a guide rail, and tilts the bucket.

  In order to solve the first problem, the invention according to claim 1 is a container lifting / tilting device applicable to a sorting machine that throws in sorting objects from above, and the first and second tilting devices are arranged in parallel in a plan view. A second rail including a second rail and a third rail, wherein the first rail has a shape extending from a horizontal first section to a horizontal third section through a second section inclined upward; Has a shape extending from a horizontal first section at the same height as the first rail to a horizontal third section through a second section inclined upward at the same angle from the first rail to a lower height than the first rail, The third rail extends horizontally through a second section inclined upward at the same angle from a horizontal first section at a position higher than the second rail to a height lower than the first rail and higher than the second rail. It has a shape extending to three sections.

  Each of the three rails can be formed by bending a steel pipe, supported and fixed by a plurality of stays at appropriate intervals corresponding to the size of the container to be lifted, and can be integrated as a container lifting and tilting device. . The container lifting / tilting device may be directly attached to the side surface of the sorting machine by a hook portion provided on a stay, for example, or may be provided with legs on the container lifting / tilting device, and may be a stand-alone caster. May be provided so as to be movable by hand. Further, regarding the total length of the container lifting and tilting device, the length and height of each section of the three rails, and the inclination angle of the second section, the size and height of the sorting machine to be applied are within the scope of the configuration according to claim 1. It can be designed arbitrarily according to the above.

  Next, in order to solve the second problem, a device according to the second aspect of the present invention provides a container lifting and tilting device according to the first aspect, in which a sorting object is provided on a first section of a first rail and a second section of a second rail. A hook for detachably connecting the suspension belt and the handle of the container when placing the container with the container suspended by a crane, and a part of the vertical side of a substantially right-angled triangular annular body. And a receiving plate having a width slightly smaller than the lateral width of the handle is provided on the upper surface of the horizontal side.

    Further, the invention described in claim 3 is the invention described in claim 2, wherein an opening portion on a vertical side of the annular body has a closing body having a bias for shifting from an open state to a closed state. It is characterized by the following.

  The annular body is a main body of a hook, and can be formed by bending a steel bar or a steel pipe, and the receiving plate can be fixed by welding a steel plate to the annular body. When the tip of the crane's hanging cable is attached to the upper part of the annular body and the handle of the container is hooked through the opening of the annular body, the handle is placed on the receiving plate. Further, when a closed body is provided at an open portion of a vertical side of the annular body, the annular body has a configuration similar to that of a mountain climbing carabiner.

  According to the container lifting and tilting device according to the first aspect, the work of stably lifting and tilting a heavy container loaded with sorting objects to a predetermined height can be easily performed only with human power. In addition, its structure is extremely simple, lightweight and low-cost, and it is easy to install, install, and remove it on the sorting machine, so it is easy to spread it to sorting places, etc., reducing the burden on workers and increasing the efficiency of sorting work. An excellent effect can be expected.

  In addition, since the hook described in claim 2 can be realized easily and at low cost and can be stably lifted by being hooked on the container by a simple operation, the operation of transferring the container from a carrier such as a truck to the container lifting / tilting device. Can be made more efficient. In addition, since the container can be easily tilted while suspended, if a hoist crane or the like can be used, the objects to be sorted in the container can be directly input to the sorting machine without using a container lifting and tilting device. It is. Furthermore, in the hook according to the third aspect, since the closure is provided at the opening of the annular body, the hook is prevented from being accidentally detached from the handle of the container, and safety during operation is improved. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  2 to 8 show an embodiment of the container lifting and tilting device according to the present invention, FIG. 2 is a front view, FIG. 3 is a plan view, and FIG. 4 is a right side view. In the container lifting / tilting apparatus 1, the first rail 11, the second rail 12, and the third rail 13 are integrally supported and fixed by stays 14, 15, and 16, and a steel plate is bent on the stay 14 and the stay 15. A hook portion 17 is provided, and the hook portion 17 is hooked and attached to the structure of the upper end and the side surface of the sorting machine S. FIG. 5 is a side view of a single unit of the first rail 11, the second rail 12, and the third rail 13, and s1, s2, and s3 indicate a first section, a second section, and a third section of each rail. The first section s1 of the first rail 11 and the second rail 12 and the third section s3 of the second rail 12 and the third rail have the same length. In addition, the ends of the first rail 11 and the second rail 12 on the first section s1 side are curved downward to be grounded, thereby achieving stability. FIG. 6 is a cross-sectional view of the container lifting and tilting device 1 taken along lines AA, BB, and CC in FIGS.

  Each of the first to third three rails 11, 12, 13 is arranged in parallel with the long side of the sorting machine. The first rail 11 and the second rail 12 place the container C thereon and move the container C in a direction along the long side of the sorting machine S. The third rail 13 contacts the side surface of the container C on the sorting machine S side. It supports this. After the worker places the container C on the first section s1 of the first rail 11 and the second rail 12, the operator pushes the container C by hand to the second section s2 that is inclined upward, and the container C is pushed up. Here, the second section s2 of the second rail 12 ends at a shorter and lower position than the second section s2 of the first rail 11 and shifts to the third section s3, but the second section s2 of the first rail 11 is To continue to a higher position, a drop occurs between the first rail 11 and the second rail 12, and the container C starts to tilt toward the sorting machine S side. When the second rail enters the horizontal third section s3, the inclination of the container C is fixed at a predetermined angle, and when the sliding of the container C is stopped at the position where the container C is put into the sorting machine S, the worker Then, if necessary, the container C is further tilted by hand, and the sorting object is scraped out and put into the sorting machine S.

  The final inclination angle of the container C is set by the height difference between the first rail 11 and the second rail 12 in the third section s3, and the average size and shape of the sorting target object, the amount to be loaded in the container C, Alternatively, it is desirable to appropriately determine the value depending on the likelihood of being damaged when put into the sorter S. For example, when the object to be sorted is plum fruit, it is preferable to set a head so that a standard container (outside size: 522 × 363 × 309 mm) is inclined at an angle of about 45 to 50 ° to the sorter S side. It is. The inclination angle of the second section s2 is also arbitrary, but is preferably about 30 to 35 ° when it is assumed that ume nuts are fully loaded in the standard container and pushed up.

  7 to 11 show an embodiment of the hook according to the present invention. FIG. 7 is a front view, FIG. 8 is a right side view, FIG. 9 is a left side view, and FIG. 10 is a bottom view. The hook 2 has a width slightly smaller than the width of the hole of the handle of the container C to be applied on the upper surface of the horizontal side of the carabiner-shaped annular body 20 which is formed by bending a steel bar into a substantially right triangle and having an opening on the vertical side. The receiving plate 22 is welded. A closing body 21 made of a steel bar is attached to the upper end side of the opening so as to be rotatable inward of the annular body 20, and the closing body 21 urges the mounting portion in a direction to close the opening. An urging mechanism (not shown) having a spring is provided. Further, a lock mechanism (not shown) for preventing the closing body 21 from rotating outward of the annular body 20 is also provided. The hypotenuse portion of the annular body 20 is covered with a rubber non-slip 23, and the hook 2 is attached to and detached from the container C by grasping the portion. FIG. 11 is a schematic diagram showing a method of attaching a hook 2 to each of the forked ends of a belt B as a suspension cable of a hoist crane (not shown) to suspend the container C.

  As shown in FIG. 11, the container C can be lifted and moved by a hoist crane after the vertical sides of the pair of hooks 2 are hooked from outside on the holding holes on both sides of the container C. Although the container C is suspended at only two points, the width of the receiving plate 22 is set to be slightly smaller than the width of the hole of the handle. The stability of the supported container C in the suspended state is significantly improved as compared with the case where the receiving plate 22 is not provided. Further, since the hook 2 is attached to the vertex of the right-angled triangle on the belt B, the operator can easily tilt the container C after moving the hook 2 onto the sorting machine S in a suspended state.

Since the closing body 21 of the hook 2 is configured to rotate toward the inside of the annular body 20 and not to rotate outward, the closing body 21 can be pressed only against the handle portion. Is opened and can be hooked on the handle of the container C. When the hook 2 is hooked on the handle of the container C, the closing body 21 automatically closes the annular body 20 by the urging mechanism. The danger of falling is also prevented. On the other hand, when removing the hook 2 from the handle of the container C, while holding the non-slip 23 and extending a finger other than the thumb and pulling the lower end of the closing body 21, the annular body 20 is opened. The hook 2 can be removed. As described above, the attachment and detachment of the hook 2 to and from the container C can be performed quickly with a single action, so that work efficiency is improved.

  As described above, the embodiments of the present invention have been described with reference to the drawings. However, the present invention is not necessarily limited to only the above-described configuration. Modifications can be made and they belong to the technical scope of the present invention as long as they are within the technical idea of the present invention.

Since the container lifting and tilting device and the hook according to the present invention can be provided at an extremely low cost, they can be easily spread in fruit sorting facilities for agricultural products such as fruits. The present invention can be widely used in distribution and manufacturing processes having a process of lifting or tilting a body or the like in an open container. In addition, the container lifting and tilting device according to the present invention can be applied not only to equipment such as fruit sorting machines but also to a truck bed or the like, so that the efficiency of the operation of loading luggage onto the bed can be improved.
