Description

The present invention relates to a conveyor for transporting articles, and more particularly to an automatic lifting mechanism of a conveyor.

Generally, in a product distribution base that collects and delivers products, when shipping a large amount of various products, a conveyor transport device is used to pick and sort the products according to the shipping destination. Since there are a huge variety and number of products, a large number of conveyor lines are densely installed as individual lines or parallel lines on the premises of a vast product collection and delivery center. Further, in the flow of goods by the conveyor, individual conveyors are often arranged in a connected manner from the upstream to the downstream of the conveyor so as to promote workability and smooth flow of the conveyor.

The vast site space of the product collection and delivery base is generally occupied with high density by such a conveyor, but at the product collection and delivery base, there are various other operations such as picking and sorting work by conveyor transportation and sorting work. Needless to say, a lot of work is required. In order to effectively utilize the site space of the vast product collection and delivery base, it is an important issue to make it possible to utilize the space occupied by the transport conveyor in combination for other work.

When the amount of work such as picking sorting and sorting is reduced, if other work, other work, etc. are to be carried out on the same floor, it is necessary to remove the heavy and long conveyor line to secure site space, but products Temporarily or as needed to temporarily or as needed to remove the conveyor lines that are mechanically connected with sufficient strength to ensure safety, quality and speed of transportation, etc. is a great loss of work, time and cost. Therefore, it cannot be said that it is a realistic response.

If there is a simple technique and method for sequentially removing and re-installing a large number of heavy and long conveyor conveyors as needed, picking work and other work that requires a conveyor line can be performed at the same collection and delivery base. It can be carried out using the floor, and the efficiency of work and utilization of the floor can be dramatically improved.

In order to easily pull up a long and sturdy heavy conveyor for transportation toward the ceiling and hang it at a high place, it is necessary to lift it with a crane and install and fix it safely. Chain or roller chain Various techniques have been studied for lifting and fixing cranes with wires and hooks. Patent Document 1 discloses a technique of a mechanism for attaching / detaching a suspended article in a hook structure at a wire tip of a crane.

Further, the same applies to Patent Document 2, and a technique that contributes to attachment / detachment of an article or fixation / attachment / detachment of the hook portion itself in the mechanism of the hook portion of the crane is disclosed. However, all of these citations are made solely by making technical improvements to the structure for the hook. However, in order to safely and temporarily fix a heavy and long device such as a conveyor by a crane to a high place, it is very dangerous to fix the hook with a chain or a roller chain or a wire. Has not yet developed the technology to present sufficient countermeasures.

The present invention has been made with the intention of solving such a problem.

Japanese Patent Application Laid-Open No. 53-64356 Japanese Unexamined Patent Publication No. 2012-473337

To temporarily remove the conveyors installed in the vast space of the product collection and delivery base on the premise that they can be repeatedly installed, the conveyors themselves should be temporarily lifted to a high place using a crane or the like and put into a safe standby state. Is the most preferable.

In general, when transporting goods in a distribution base by conveyor, first, the goods that have arrived or received are put into the conveyor line, and then gradually transported to a lower position according to the flow or branching of the conveyor line. There are many. Among them, an inclined conveyor is often used to convey an article from a high place to a low position. Since the high part of such an inclined conveyor has sufficient height allowance for performing other work under it, for example, the low part on the other side of the inclined conveyor is lifted by a lift. If the raised conveyor can be safely and automatically fixed and held on the ceiling, the space of the inclined conveyor installation portion can be diverted to other work.

The present invention provides a holding mechanism for safely and stably holding an inclined conveyor lifted by an overhead crane in a hollow ceiling portion with a simple operation, and easily suspends the inclined conveyor. The challenge is to develop a detachable holding mechanism that allows the holding mechanism to be released and the floor surface to be re-installed.

While keeping one side of the heavy long conveyor fixed to the conventional upstream high-altitude conveyor, the other side of the conveyor, the low-lying part, is hung, safely fixed to the ceiling, and the conveyors are sequentially installed when necessary. It is necessary to be able to hang it down and reconstruct and utilize it as a conveyor conveyor line.

In order to solve such a problem, the lifting and lowering device with an automatic attachment / detachment mechanism according to the present invention is used.
Inclined conveyors, either alone or connected in an article transport conveyor line,
A moving means that allows the inclined conveyor to move upward in order to provide a work space below the inclined conveyor, and a moving means that enables the inclined conveyor to move upward.
It is characterized in that it is provided with a moving / fixing mechanism for the inclined conveyor, which is a fixing means for moving and fixing the inclined conveyor upward by the moving means.
The lifting and lowering device with an automatic attachment / detachment mechanism according to the present invention is specifically a tilted conveyor independently or connected in an article transport conveyor line, a lifting mechanism portion laid on the tilted conveyor, and the lifting mechanism. The hook mechanism part of the hook, the fixed tip part of the lifting mechanism part of the inclined conveyor, which has a hinge structure that can rotate in the vertical direction, and the part connected to the lifting mechanism part from the ceiling direction. A device for lifting the inclined conveyor in a one-sided support form and a ceiling hanging metal fitting mechanism for suspending and fixing the hanging hook mechanism of the lifting mechanism on the ceiling are provided. Since the conveyor has a hook portion structure, it is characterized in that it can automatically stop and release the hook with the ceiling hanging metal fitting.

The lifting / lifting device with an automatic attachment / detachment mechanism according to the present invention is a release plate that can rotate within a certain range on the hook portion, and automatically hooks and releases the ceiling suspension fitting and the hook portion. It is characterized by being a release plate that can be used.

According to the lifting / lifting device with an automatic attachment / detachment mechanism according to the present invention, a tilting conveyor in a heavy and long article transport conveyor line is lifted by a hoisting machine (lifting / lowering machine) in the vicinity of the other end while being supported on one side. By doing so, it can be safely and easily removed. Further, the inclined conveyor can be installed again by performing the reverse suspension start when necessary.

The inclined conveyor preferably has a lifting mechanism portion provided with a hook structure for lifting in the vicinity of the low end side end portion, and the ceiling via a chain connected to the upper portion of the lifting mechanism portion, a roller chain, a wire, or the like. It is lifted by a crane laid in the section. However, although it is assumed that this lifting mechanism portion is provided near the low end side end portion of the inclined type conveyor, the position may be substantially an intermediate portion of the inclined side conveyor, and the present invention limits the position. is not it.

A strong and preferably rod-shaped ceiling hanging bracket is laid on the ceiling part, and the hook part installed on the upper part of the lifting mechanism part is hooked, so that the lifted inclined conveyor can be safely lifted. Can be temporarily installed. The ceiling hanging bracket may be in a form in which the hook of the lifting mechanism is safely and securely hooked.

The hook portion of the lifting / lowering device with an automatic attachment / detachment mechanism according to the present invention has an inclined portion on the head in its shape, and the hook portion is automatically activated when the rod-shaped ceiling hanging bracket abuts on the inclined portion of the head. It is tilted and has a structure in which the ceiling hanging bracket is automatically hooked to the hook portion as the tilting conveyor rises. (See FIG. 3) Hereinafter, this structure will be referred to as a “hook structure”. Further, a mechanical portion having a hook structure is referred to as a "hook portion".

The present invention does not limit the number of hook portions, but since it is a mechanism for suspending an inclined conveyor, the description will be made on the premise that a total of two hook portions are provided on the left and right sides of the conveyor in a well-balanced manner. .. Of course, the number of hooks may be one or two or more.

The hook portion of the lifting / lowering device with an automatic attachment / detachment mechanism according to the present invention has a substantially triangular rotating plate that can rotate in the vertical direction on the handle portion under the hook. Hereinafter, it will be referred to as a "release plate" and will be a structure included in the hook portion. When suspending the inclined conveyor, the hook portion must be automatically removed from the ceiling suspension bracket. At this time, the inclined conveyor is temporarily lifted by a lifting device such as a crane. At this time, the ceiling suspension fitting is automatically disengaged from the hook by being abutted and guided by the inclined portions on both sides of the release plate, and returns to the inclined portion of the head portion of the hook portion. That is, in order to prevent the hook from being blocked by the substantially tip of the two-sided inclined portion of the release plate coming into contact with the lower end of the inclined portion of the head of the hook portion and the ceiling hanging bracket being hooked to the hook again. In addition, the above-mentioned hook release movement becomes possible. Further, from the time when the ceiling suspension fitting moves from the upper side inclined portion to the lower side inclined portion of the two inclined portions of the release plate, the inclined conveyor is suspended downward by the crane. Although the release plate is described as a rotating plate having a substantially triangular shape in FIG. 4, other shapes may be used as long as the release plate can function as a release plate as described here. The shape of the release plate is not limited to a substantially triangular shape.

When the release plate of the hook portion is brought into contact with the ceiling hanging bracket, the hook portion is inclined to lead to the release of the hook. All of the above movements of the hook portion do not require power, and are automatically performed only by raising and lowering the inclined conveyor by a device for lifting from the ceiling. The hook portion structure of the present invention is defined as a structure that exerts the functions of automatically hooking and releasing the hook portion to the ceiling suspension fitting of the inclined conveyor. The hook portion structure is a concept including similar structures having the same function, and these are included in the present invention.

The lifting / lifting device with an automatic attachment / detachment mechanism according to the present invention is also characterized in that the connecting portion between the lifting mechanism portion and the inclined conveyor has a hinge structure that can rotate.

The lifting mechanism portion provided with the hook portion is connected to the inclined conveyor, but the connecting structure is such that the lifting mechanism portion has a hinge structure that can rotate with respect to the conveyor flow direction, so that the ceiling of the hook portion is connected. When the hook is hooked and released from the upper hanging metal fitting, the above-mentioned tilting movement due to the contact of the hook portion with the ceiling hanging metal fitting can be supported at the same time. In this case, it is not necessary to use a rotatable hinge structure for joining the hook portion and the lifting mechanism portion. This leads to structural reinforcement of the entire lifting mechanism.

However, the present invention does not prevent the hinge structure from being rotatable when the hook portion and the lifting mechanism portion are joined.

The lifting mechanism of the lifting / lifting device with an automatic attachment / detachment mechanism according to the present invention has an automatic hooking structure of a lifting mechanism laid on an inclined conveyor, a connecting mechanism thereof, a ceiling hanging bracket, and a hook portion mechanism for hooking to a rod-shaped bracket. Reach. However, the detailed shape, size, and material of the lifting mechanism, hook, release plate, ceiling hanging bracket, etc. are not limited to the contents of one embodiment described later, and the functions described in detail are invented. It is the essence. Needless to say, the positions of the hook and the hanging bracket can be upside down.

According to the lifting and lowering device with an automatic attachment / detachment mechanism according to the present invention, it is safe and easy to lift a slanted conveyor in a heavy and long article transport conveyor line with a crane, for example, in the vicinity of the other end while one side is instructed. Can be removed. Further, the inclined conveyor can be installed again by performing the reverse suspension start when necessary. These can be automatically and safely performed by the hook mechanism of the hook portion provided in the lifting mechanism portion. Then, it is possible to present technical means for effective utilization of the site floor at the product collection and delivery base.

According to the present invention, while one side of a heavy long conveyor is fixed to the conventional upstream high-altitude conveyor, the low-altitude portion on the other side of the conveyor is hung and safely and automatically on the ceiling. It can be fixed and, when necessary, the conveyors can be hung up and down again, and can be reconstructed and utilized as a conveyor conveyor line.

Then, in a product delivery base having a large number of goods transport conveyor lines, the inclined conveyor that is a part of the transport line can be arbitrarily removed or re-installed as needed, so that the site floor of the product collection and delivery base can be selected. It opens the way for effective utilization and can contribute to the dramatic improvement of effective utilization. In addition, it is possible to not only safely lift a heavy conveyor to the ceiling, but also to ensure the safety of the site floor, as well as to significantly improve the workability of workers and the economic efficiency. A delivery base or a distribution base will be realized.

It is a perspective conceptual diagram which showed the whole image of the lifting-lifting apparatus with an automatic attachment / detachment mechanism which concerns on one Embodiment of this invention. It is a conceptual diagram which showed the lifting mechanism part of the lifting mechanism with the automatic attachment / detachment mechanism which concerns on one Embodiment of this invention. It is a conceptual diagram which showed the mode in which the hook part of the lifting and lowering device with an automatic attachment / detachment mechanism which concerns on one Embodiment of this invention is hooked on a bar-shaped metal fitting. FIG. 5 is a conceptual diagram showing a mode in which a hook portion of a lifting / lowering device with an automatic attachment / detachment mechanism according to an embodiment of the present invention is released from a rod-shaped metal fitting.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following, the range necessary for the explanation for achieving the object of the present invention will be schematically shown, and the range necessary for the explanation of the relevant part of the present invention will be mainly described. It shall be based on a known technique.

FIG. 1 is a conceptual diagram showing an overall image of a lifting / lowering device with an automatic attachment / detachment mechanism according to an embodiment of the present invention. The figure is an external view of the inclined conveyor viewed from the side, and is a state in which the inclined conveyor of the lifting and lowering device with an automatic attachment / detachment mechanism according to the embodiment of the present invention is installed on the floor surface and an overhead crane. Both of the suspended states are illustrated. First, the inclined conveyor 11 installed on the floor surface is installed on the floor surface 13 in which the left side is a high place end and the right side end is a low place in FIG. 1, for example.

For example, it is assumed that the article to be conveyed by the conveyor is conveyed from the high-altitude end portion to the low-altitude end portion on the right side by the inclined conveyor 11, and the following description will be given. However, the low part of the inclined conveyor may be upstream in the transportation of the article, and the article may be transported to the high place on the inclined part, but it goes without saying that the present invention can deal with any of these cases. The high part of the inclined conveyor is connected to the upstream conveyor, and the height difference is often sufficiently higher than the height of a person.

The downstream low end is connected to another downstream conveyor, and the inclined conveyor shown in this figure is positioned as a conveyor that performs inclined conveyance, which is a part of a series of connected conveyors. Since the lower part of the inclined conveyor is installed on the floor, it is ready for human work. A lifting mechanism portion 20 is laid near the low end on the downstream side of the inclined conveyor. A lifting device such as a crane is installed on the ceiling portion 14, but the figure is omitted. In the following, the case where the lifting device is an overhead crane will be described. The crane is located substantially directly above the lifting mechanism portion 20 of the inclined conveyor 11.

As shown in FIG. 1, a lifting chain 16 is connected to an overhead crane at the upper part of the lifting mechanism portion 20. The chain 16 is hoisted by a crane, which is a lifting device, and the inclined conveyor 11 is lifted upward, and is lifted and fixed to the state of the inclined conveyor 12 shown in FIG.

Although not shown in the figure, the upstream side of the inclined conveyor 11 at a high place is connected to another upstream conveyor. Since the connecting portion is connected by a hinge structure that can rotate in the vertical direction, the hinge structure connecting portion rotates even during the lifting operation of the inclined conveyor 12, so that the inclined conveyor 12 is lifted by the lifting device. It can be lifted and lifted from the vicinity of the low end. Of course, this hinge structure may also be capable of moving in the left-right direction.

A hook portion (referred to as a “spear-shaped hook portion” for convenience of drawing) 30 is laid on the upper portion of the lifting mechanism portion 20. The tip of the ceiling hanging metal fitting 24 laid below the ceiling has a rod-shaped metal fitting 31, which is a mechanism to be hooked by a spear-shaped hook portion 30. That is, the inclined conveyor 12 is suspended and fixed in the air by the chain 16 of the crane from the ceiling and the spear-shaped hook portion 30 hooked on the rod-shaped bracket 31 of the ceiling suspension bracket 24 via the lifting mechanism portion 20. It will be in the state of being done.

FIG. 2 is a conceptual diagram showing a lifting mechanism portion of a lifting / lifting device with an automatic attachment / detachment mechanism according to an embodiment of the present invention. This figure is a conceptual view of the inclined conveyor of FIG. 1 as viewed from the downstream side of a low place on the right side. The lifting mechanism portion 20 in this figure is lifted upward by the chain 16 of the crane.

As shown in FIG. 2, the lifting mechanism portion 20 has, for example, a portal shape, and both foot portions thereof are connected to both side surfaces of the inclined conveyor 12. A chain 16 from the overhead crane 15 is connected to the substantially central portion of the upper part of the lifting mechanism portion 20. When the device 15 for lifting from the ceiling operates to wind up the chain 16, the inclined conveyor 12 is lifted from the floor surface together with the lifting mechanism portion 20, and is fixed and hollowly fixed in the vicinity of the ceiling. The shape of the lifting mechanism portion 20 is not limited to the portal shape.

As shown in FIG. 2, ceiling hanging metal fittings 24 are firmly installed from the ceiling on both sides of the device 15 for lifting the ceiling 14. Needless to say, the lower tip of the ceiling hanging metal fitting 24 is a rod-shaped metal fitting pipe (rod-shaped metal fitting 31), which has sufficient strength to withstand the weight of the inclined conveyor 12. On the other hand, spear-shaped hooks 30 are laid on both sides of the upper part of the lifting mechanism portion 20, and the hooks of the spear-shaped hook portions 30 are attached to the rod-shaped metal fittings 31 at the lower end of the ceiling hanging metal fittings 24. It will be stopped. Here, it is not necessary to limit the number of the hook portion 30 and the rod-shaped metal fitting 31. It may be 1 or more and is technically selected according to the size and weight of the inclined conveyor.

It is not only the fixing by the chains 16 from the crane 15 but also the spear-shaped hooks 30 laid on both sides of the lifting mechanism 20 that lifts and fixes the heavy inclined conveyor 12 from the overhead crane 15 in a one-sided support mode. By hooking it on the rod-shaped metal fitting 31 suspended from the ceiling, safer and more reliable fixing can be achieved. Further, the hooking by the hooking spear-shaped hook portion 30 also contributes to the prevention of shaking of the inclined conveyor 12 in the hollow state.

The lifting mechanism portion 20 and the spear-shaped hook portion 30 are connected by a rotatably rotatable hinge structure 32. As shown in FIG. 1, since the lifting mechanism portion 20 is rotated and rotated at the connecting portion with the inclined type conveyor 12 due to the lifting and raising of the inclined type conveyor 12, the hinge structure of the foot connecting portion of the lifting mechanism portion 20 The effect of construction 32 is great. Further, the hinge structure 32 also rotates when the spear-shaped hook portion 30 is automatically hooked to the rod-shaped metal fitting 31, and fulfills an important function.

Next, a mode in which the spear-shaped hook portion 30 of the lifting mechanism portion 20 is hooked on the rod-shaped metal fitting 31 of the ceiling hanging metal fitting 24 will be described in detail.

FIG. 3 is a conceptual diagram showing a mode in which a hook portion of a lifting / lowering device with an automatic attachment / detachment mechanism according to an embodiment of the present invention is hooked on a rod-shaped metal fitting. The figure shows a spear-shaped hook portion 30 laid on the upper portion of the lifting mechanism portion 20 by a hinge mechanism capable of rotating and rotating, and a substantially triangular release laid on the spear-shaped hook portion in a rotatable manner. The plate 33 and the rod-shaped metal fitting 31 below the ceiling hanging metal fitting are shown. In these explanations, the "spear-shaped hook portion" and the "substantially triangular release plate" are shape representations used as an example in order to explain their functions in an easy-to-understand manner, and the shapes of the hook portion and the release plate are described. It is not limited. Any shape that enables the functions described below shall be included in the concept of the hook portion and release plate of the present invention.

FIG. 3 is an external view of the structure as viewed from the side surface side of the inclined conveyor. Further, the figure shows the movement of the spear-shaped hook portion 30 and the lifting mechanism portion 20 until they are hooked on the rod-shaped metal fittings 31 from the figure shown on the left side to the figure shown on the right side in order with arrows. The ceiling hanging metal fitting 24 is omitted in order to make the figure easier to understand, and only the rod-shaped metal fitting 31 is described in cross section. The lifting mechanism 20 and the spear-shaped hook portion 30 are raised or lowered by the crane chain, and the spear-shaped hook portion 30 is tilted to the left or right. The position of the rod-shaped metal fitting 31 of the ceiling hanging metal fitting does not move.

The position of the rod-shaped metal fitting 31 of the ceiling hanging metal fitting is fixed from the ceiling, and it is also fixed in FIG. The spear-shaped hook portion 30 is gradually raised from the lower side to the upper side by the crane when the inclined conveyor is lifted. Therefore, when the spear-shaped hook portion 30 gradually rises and its head inclined portion 34 comes into contact with the rod-shaped metal fitting 31, it is pushed by the rod-shaped metal fitting 31 and gradually inclines to the right in FIG. 3 (FIGS. 3, a to b). ). FIG. 3 shows a mode in which the spear-shaped hook portion 30 is rotated and inclined at the hinge connecting portion with the lifting mechanism portion 20. However, the spear-shaped hook portion 30 may be gradually inclined around the rotatable connecting portion with the inclined conveyor together with the lifting mechanism portion 20.

The rod-shaped metal fitting 31 reaches the lowermost portion of the head inclined portion 34 of the spear-shaped hook portion 30 , and the spear-shaped hook portion 30 is hooked on the rod-shaped metal fitting 31 of the hanging metal fitting (from c to d in FIG. 3). The spear-shaped hook portion 30 and the lifting mechanism portion 20 that have returned to the vertical state due to the reaction of being pushed by the rod-shaped metal fittings as shown in c, c-1, and d in FIG. 3 are vertically suspended together with the rod-shaped metal fitting 31 of the ceiling suspension metal fitting. It will be in the lowered state, and at the same time, the lifting and fixing of the inclined conveyor will be completed.

Next, a mode in which the spear-shaped hook portion of the hook mechanism portion is released from the state of being hooked on the ceiling suspension fitting will be described.

FIG. 4 is a conceptual diagram showing a mode in which a spear-shaped hook portion of an embodiment of a lifting / lowering device with an automatic attachment / detachment mechanism according to an embodiment of the present invention is released from a rod-shaped metal fitting. Similar to FIG. 3, the figure is also laid on the spear-shaped hook portion 30 and the spear-shaped hook portion laid by a hinge mechanism capable of rotating and rotating on the upper portion of the lifting mechanism portion 20 in a rotatable manner. The release plate 33 and the rod-shaped metal fitting 31 below the ceiling hanging metal fitting are shown.

Further, FIG. 4 is an external view of the above structure as viewed from the side surface side of the inclined conveyor as in FIG. The figure shows the movement of the spear-shaped hook portion 30 and the lifting mechanism portion 20 from the figure shown on the left side to the figure shown on the right side in order with arrows until the hook is released from the rod-shaped metal fitting 31. The ceiling hanging metal fitting 24 is omitted in order to make the figure easier to understand, and only the rod-shaped metal fitting 31 is described in cross section. The lifting mechanism 20 and the spear-shaped hook portion 30 are raised or lowered by the crane chain, and the spear-shaped hook portion 30 is tilted to the left or right. The position of the rod-shaped metal fitting 31 of the ceiling hanging metal fitting does not move.

When the hook is released, the inclined conveyor, the lifting mechanism portion 20, and the spear-shaped hook portion 30 are once pulled upward by the crane. As a result, the rod-shaped metal fitting 31 that is detached downward from the spear-shaped hook portion 30 apparently moves downward along the handle 35 of the spear-shaped hook portion 30 (FIGS. 4, D to E). The rod-shaped metal fitting 31 hits the triangular plate-shaped release plate 33 laid on the handle 35 of the spear-shaped hook portion 30, and moves downward along the slope (upper) 36 of the inclined portion on both sides of the triangular plate (FIG. 4, e). From to f).

The release plate 33 is fixed with a structure that is partially rotatable about a fixed shaft of the spear-shaped hook portion 30 with the handle 35. As the spear-shaped hook portion 30 and the lifting mechanism portion 20 are raised by pulling up the crane chain, the rod-shaped metal fitting 31 moves on the 36 slopes of the release plate 33 and reaches the slope (bottom) 37 of the inclined portions on both sides (FIG. 4). , To to chi). When the rod-shaped metal fitting 33 reaches the slope (bottom) 37 of the two-sided inclined portion of the release plate, the chain of the lifting device gradually lowers the inclined type conveyor, the lifting mechanism portion 20, and the spear-shaped hook portion 30. Start unloading. Then, the release plate 33 rotates, and the tip portion 38 where the slope (upper) and the slope (lower) of the two-sided inclined portion intersects with the lower portion 39 of the spear of the spear-shaped hook portion 30 and the rotation of the release plate 33 stops ( Fig. 4, from the beginning to the end).

Then, the rod-shaped metal fitting 31 moves upward on the head inclined portion 34 of the spear-shaped hook portion in accordance with the descent of the spear-shaped hook portion 30. As described above, the spear-shaped hook portion 30 tilts to the right in FIG. 4 due to the pressure of the rod-shaped metal fitting 31, the rod-shaped metal fitting 31 comes off the tip 38 of the two-sided inclined portion 38 of the release plate 33, and at the same time, from the hook of the spear-shaped hook portion 30. It comes off (Fig. 4, Li to Nu). After that, the entire inclined conveyor is gradually lowered by the lifting device and re-installed on the floor surface.

The structure of the spear-shaped hook portion 30 of the lifting and lowering device with an automatic attachment / detachment mechanism according to one embodiment of the present invention does not require any power when the inclined conveyor is lifted and stopped, and the spear-shaped hook portion is released. Since the entire lifting mechanism 20 including the 30 is connected and fixed to the inclined conveyor by a hinge structure that can rotate in advance, the rod-shaped metal fitting 31 is used when the hooking / stopping is stopped and the hanging / stopping is released from the ceiling hanging metal fitting. It can move smoothly in a tilted manner. Similarly, this tilting movement does not require power.

As a result, the slanted conveyor, which is a heavy object, is automatically hooked to the hanging bracket installed on the ceiling only by pulling up and pulling down the crane, and is safely hooked and fixed so that it will not come off. Even when removing the hook, the hook can be released safely and easily automatically only by pulling up and pulling down the lifting device. No power other than the crane lifting device is required to hook and release the hook portion and the hanging metal fitting in the present invention. The rotatable hinge-type connection of the lifting mechanism with the inclined conveyor not only rotates the connection angle with the lifting mechanism as the inclined conveyor rises, but also hooks the spear-shaped hook with the hanging bracket. The function of rotational movement can be doubled even when the device is stopped and released.

The lifting mechanism of the lifting and lowering device with an automatic attachment / detachment mechanism according to an embodiment of the present invention is a lifting mechanism portion laid on an inclined conveyor, a connecting mechanism thereof, a ceiling hanging bracket, and a hook portion mechanism for hooking to a rod-shaped bracket. It extends to the automatic hooking structure. However, the detailed shape, size, and material of the lifting mechanism, hook, release plate, ceiling hanging bracket, etc. are not limited to the contents of the above-mentioned one embodiment, and the functions described in detail are invented. It is the essence.

Therefore, the same technique having the same function regardless of the detailed shape or the like is also included in the present application, and various modifications can be made without departing from the gist of the present invention. Therefore, all of these are part of this technical idea.

As described above, according to the invention of the present application, the inclined conveyor in the goods transport conveyor line can be temporarily and easily removed to the ceiling surface at the product collection and delivery base. It can be utilized and utilized for the purpose of. In addition, it is safe to fix the inclined conveyor for temporary removal of the ceiling, and it is easy to install the inclined conveyor again.

Compared with the conventional removal of the front surface of the conveyor, this work can significantly improve safety and workability, and can also significantly improve economic efficiency.

The present invention is not limited to the product collection and delivery base, and can be used and applied to work using a conveyor line for all materials and uses. Therefore, the present application brings great benefits to various industries other than the logistics industry.
