Description

The present invention relates to a transfer conveyor switching device, and more particularly to the use of wheels in the structure of a confluence point when articles conveyed from a sub-conveyor composed of a plurality of left and right conveyors merge into a main conveyor. ..

Conventionally, various conveyors have been developed as a conveyor for merging articles to be conveyed from a plurality of parallel conveyors and sequentially carrying the articles to a single main conveyor.

When transporting an article on a conveyor, it is essential to change the transport path that also serves to sort the article, and the transport conveyor needs a branch point or a confluence point. There are various types of conveyors such as belt type, narrow belt type, roller type, etc., and various technological developments such as a chute mechanism for moving articles as a method of transferring articles to be conveyed at the branch point or confluence of the conveyor. Is being done.

In the process of transporting goods by a conveyor, high-speed logistics has become the mainstream for the development of methods for transferring goods at branch points or confluences that protect the goods from impacts and change the course safely and accurately without damaging them. This is an extremely important issue in modern product distribution bases.

As a technique for transferring articles on such a conveyor, for example, Patent Document 1 describes a main conveyor including a long belt conveyor that receives articles from a carry-in conveyor and transfers them to a carry-out conveyor, and a main conveyor thereof. There is a technical disclosure consisting of a side carrier arranged side by side and a sub-conveyor consisting of a short belt conveyor that receives articles from other carry-in conveyors and transfers them to the side conveyors.

The main configuration in this technology is to transport a transport surface formed by arranging a large number of slats slidable in the longitudinal direction with shoes (article chute mechanism) for guiding the article by the side transport body in the transport direction. In the length direction of the slat of the shoe so that the article can be swiveled at the front-rear position of the shoe so that it can run endlessly and the article transferred from the sub-conveyor is transferred from the transport surface to the main transport in the transport process. It is a structure equipped with a regulatory mechanism that regulates the position.

However, in the structure using these slats shoes, when sorting the transported articles, the objects to be transported are a mixture of articles having various shapes and dimensions, so that when the direction of the articles is changed to the main carrier, the articles are changed. The force of the shoe to be given to the article changes greatly depending on the weight of the article.

For this reason, it is conceivable that the article may be damaged by the impact, etc., depending on the transported object, such as when the article shakes greatly. In some cases, it may fall off from the conveyor and be damaged. It is very difficult to control the impact load from the shoe to the article for articles with various shapes and dimensions due to the complexity of control, and it is not preferable from the viewpoint of cost to add a function to the article. , It is not sufficient as a transfer technology for goods.

As shown in these disclosed techniques, in the transfer of articles, a long conveyor range is required for branching or merging of belt conveyors, and in many cases, means for sequentially moving articles by shoes or the like is required, and the conveyor branching or conveyor is used. We have not yet reached a technology to safely and surely change the course of articles using a simple system between conveyors of the same quality at the time of merging.

In this way, a transfer technology that enables smooth transfer of goods at branch points or confluences on the conveyor corresponding to changes in the transfer route of goods on a high-speed conveyor that supports high-speed serving of goods at distribution collection and delivery bases. The challenge is to develop.

When moving and transferring goods including fragile goods on a conveyor, it is required to present a technical means for changing the conveyor transport direction or route at high speed while preventing damage accidents of the goods.

The present invention does not require complicated control, especially for the purpose of smooth transfer of articles at the confluence of conveyors, and by changing the direction of rotation and the position of the height of the wheels, the articles merge regardless of the shape and dimensions of the articles. An object of the present invention is to provide a wheel type direction change device capable of changing a direction at a point.

In order to solve such a problem, the wheel type direction changing device according to the present invention is used.
A shaft shaft having a first drive axis direction in a direction substantially orthogonal to the transport direction of the transport article on the conveyor,
A first drive rotating body that is pivotally supported by the first drive shaft and transmits a rotational force,
A winding body that is wound around the first driving rotating body and transmits the rotational force,
A second rotation transmitter that is wound around the winding body and rotates a second axis by a rotational force transmitted from the winding body.
A third rotating body that is slidably contacted with the second rotation transmitting body at a constant inclination angle and is pivotally supported by limiting free rotation around the axis with respect to the second axis.
It is characterized in that an annular rotating body rotatably mounted around the second axis is provided on the outer periphery of the third rotating body.

The wheel type direction changing device according to the present invention is a wheel type direction changing device having the shaft shafts that support a plurality of the wheel type direction changing devices as one shaft shaft unit and having two or more of the shaft shaft units. Therefore, the upper end of the outer periphery of the annular rotating body of the shaft shaft unit is set so as to project higher than the bottom surface of the transported article on the transport conveyor, and the protruding dimension can be freely set for each shaft shaft unit. ..

That is, in the wheel type direction changing device according to the present invention, the upper end of the outer circumference of the annular rotating body that rotates about the second axis is set so as to project slightly higher than the bottom surface of the transported article on the transport conveyor. Therefore, when the wheel type direction changing device according to the present invention is installed between the belts of the narrow belt type conveyor or between the rollers of the roller type conveyor, the conveyed article rides on the wheel type direction changing device by inertial force. Then, the outer peripheral upper end portion of the annular rotating body that rotates about the second axis guides the bottom surface of the conveyed conveyed article that has been ridden in the rotational direction by the rotational force.

On the other hand, in the wheel type direction changing device according to the present invention, the second axial direction, which is the rotation direction of the substantially disk-shaped annular rotating body, has a constant inclination angle with respect to the shaft axis, which is the first drive shaft direction. Therefore, the rotation direction of the outer peripheral upper end portion of the annular rotating body can be changed by 360 degrees with respect to the traveling direction of the conveyed article by the fixed position of the rotation angle of the first shaft shaft that can rotate.

The wheel-type direction changing device according to the present invention is a wheel-type direction changing device having the above-mentioned shaft shaft having a plurality of the above-mentioned wheel-type direction changing devices as one shaft shaft unit and having two or more of the above-mentioned shaft shaft units. The outer peripheral upper end portion of the annular rotating body of the shaft shaft unit 1 is set so as to project higher than the bottom surface of the conveyed article on the transport conveyor, and the outer peripheral upper end portion of the annular rotating body of the second or third shaft shaft unit is set. Is characterized in that it is easy to pull in the transported articles at the confluence of the transport conveyors by setting the wheels to gradually protrude higher.

Therefore, the wheel-type direction changing device according to the present invention can guide the bottom surface of the mounted conveyed article in an arbitrary direction by the rotational force of the outer peripheral upper end portion of the annular rotating body. Further, since the shaft shaft unit provided with the plurality of wheel type direction change devices protrudes onto the conveyor from between the roller conveyor or the narrow conveyor as a plurality of rows of shaft shaft units in parallel, the plurality of wheel type direction change devices can be used. It will occupy a certain area of the confluence on the conveyor.

That is, in the wheel type direction changing device according to the present invention, a plurality of wheel type direction changing devices can be provided side by side on one shaft shaft, which is used as one shaft shaft unit, and the shaft shaft units are arranged in parallel. By installing it, a certain area on the transport conveyor can be occupied by the wheel type direction changing device.

When the article transported on the conveyor reaches the confluence point occupied by the plurality of wheel-type direction changers described above when it joins the main conveyor, it reaches the confluence point and is on the annular rotating body of the protruding wheel-type direction changer. It is driven onto the main conveyor and guided into the main conveyor by its rotational driving force. Since the annular rotating body rotates at a constant angle that is convenient for turning the merged articles in the traveling direction of the main conveyor, the articles are smoothly transferred to the main conveyor and changed direction. Can be planned.

A plurality of wheel-type direction changers can guide the bottom surface of the transported article that has climbed onto a certain area at the confluence in a certain direction. Further, since the protrusion dimension of the outer peripheral upper end portion of the annular rotating body of each wheel type direction changing device to the conveyor upper surface can be arbitrarily set, for example, the protrusion dimension of the outer peripheral upper end portion of the annular rotating body to the conveyor upper surface is gradually increased. If it is set so as to be, the merging conveyed articles can be gradually and smoothly pulled into the wheel type direction changing device and run on. That is, it is possible to smoothly ride on the merging point having a plurality of wheel type direction changing devices without giving an impact and damaging the merging conveyed articles.

Similarly, the wheel type direction changing device according to the present invention is a wheel type direction changing device having a shaft shaft having a plurality of wheel type direction changing devices as one shaft shaft unit and having two or more shaft shaft units, and is a shaft shaft. By setting the protrusion dimension on the conveyor at the upper end of the outer peripheral portion of the annular rotating body of the unit to gradually decrease toward the front in the traveling direction of the main conveyor, the conveyor confluence point to the front of the main conveyor. It is possible to easily and smoothly deliver the conveyed article toward the user.

In the wheel type direction changing device according to the present invention, the shaft shaft unit moves up and down or rotates for each shaft shaft unit according to the transport position detection information of the transported article, so that the upper end portion of the outer periphery of the annular rotating body of the shaft shaft unit is formed. It is characterized in that the height can be arbitrarily changed and the angle between the rotation direction of the outer peripheral upper end portion of the annular rotating body of the shaft shaft unit and the shaft shaft can be arbitrarily changed.

Therefore, the plurality of wheel-type direction-changing devices can guide the bottom surface of the conveyed article on the wheel-type direction-changing device in a fixed direction at each rotation angle. For example, the conveyed goods merging from the original conveyor to the main conveyor can be smoothly drawn in and guided in the traveling direction of the main conveyor by the wheel type direction changing device, so that the conveyed goods are impacted or damaged at the time of merging the conveyors. Can be changed without giving.

In the wheel type direction changing device according to the present invention, the shaft shaft having the first drive shaft direction can be set to be substantially parallel to the transport direction of the transport article on the transport conveyor.

That is, since the shaft shaft units can be arranged parallel to the traveling direction of the conveyor, when a plurality of shaft shaft units are installed in parallel in the traveling conveyor direction, for example, they are lined up by one shaft shaft in the traveling direction. Only the wheel type direction changer can be moved and changed in the vertical direction. Similarly, only the wheel type direction changer lined up by one shaft shaft in the traveling direction is set by changing the angle setting by the rotation of the shaft shaft and changing the rotation guidance direction of the outer peripheral upper end portion of the annular rotating body. You can also do it.

The wheel-type direction changing device according to the present invention has a wheel-type direction changing mechanism on the main conveyor at the merging point in the conveyor merging and changing of the conveying direction of the goods by the conveyor, so that the conveyor is the original conveyor that merges. It is possible to smoothly transfer articles to the main conveyor that merges from the conveyor and change the conveyor direction.

The wheel type direction changing device according to the present invention is not limited in the number of annular rotating bodies. For example, it suffices to have a plurality of shaft shaft units having a plurality of annular rotating bodies, and a wheel type direction changing device can be set according to the width and speed of the transport conveyor and the size of the article to be transported. An article that rides on a plurality of rotating annular rotating bodies that are lined up in a fixed form due to the inertia of traveling and moving at a transport speed is oriented in the transport direction of the main transport conveyor that smoothly merges according to the rotation speed and direction of the rotating moving body. It can be changed and guided, and in some cases the speed can be changed.

In the wheel type direction changing device according to the present invention, the annular rotating body rotates by receiving the rotational force of the driving rotating body that presses against the rotation transmitting body on the outer periphery of the annular rotating body, so that the object to be conveyed is in contact with the same shaft shaft unit. It is possible to promote a smooth and continuous change of direction of the article by driving and rotating according to the time.

Further, in the wheel type direction changing device according to the present invention, the protrusion amount, the rotation direction, the rotation angle, and the rotation of the annular rotating body of the plurality of wheel type direction changing devices attached to the shaft shaft by setting the rotation angle of the shaft shaft. The speed can be controlled freely.

In addition, when the articles are merged into the main conveyor, the articles can be prevented from falling out of the conveyor due to the inertial impact caused by the change in the traveling direction angle between the original conveyor and the main conveyor and the speed change. Defensive fences such as guide rails are no longer required. Further, since the pulling force can be applied to the side where the frictional resistance between the conveyed article and the annular rotating body is large, the direction of the conveyed article can be smoothly changed. This can also be used for Tailgating and branching of transported articles.

The wheel type direction changing device according to the present invention can be installed not only in the narrow belt type conveyor but also in the roller type conveyor by adjusting the distance between the rollers and the outer diameter dimension of the annular rotating body. In the present invention, it is not necessary to particularly limit each dimension of the constituent article.

The wheel type directional change device according to the present invention enables smooth directional change without giving an excessive impact to the object to be conveyed in the switching device of the merging / sorting conveyor, and further, the directional displacement amount can be gradually set. As a result, the amount of slip on the conveyor of the article is small, and the lateral vibration and vibration of the object to be conveyed are also reduced, so that the distance between the adjacent articles to be conveyed in the front-rear direction can be reduced, and the article is mounted on the conveyor. Since the loading density of the object to be transported can be increased, the transport efficiency can be further improved.

In the wheel type direction changing device according to the present invention, the rotation direction of each annular rotating body configured in a plurality of stages can be arbitrarily set, and the amount of protrusion from the conveyor can be arbitrarily set. That is, the wheel type direction changing device according to the present invention can be used regardless of the angle at which the original conveyor that merges merges with the main conveyor and any article that is conveyed. Since all the annular rotating bodies can be arbitrarily set to the rotation direction and the protrusion amount at which the merging direction conversion is most likely to be performed, safe and smooth transfer merging is possible without giving an impact to the article.

According to the present invention, a wheel-type directional change device capable of significantly improving the safety and work efficiency of transported articles and also significantly improving economic efficiency is realized.

It can be changed and fixed for each body. As shown in FIG. 7, by changing and fixing the fixing angle of the fixing portion of the third rotating body 214 with respect to the shaft shaft, the annular rotating body has the same shaft shaft unit as, for example, α1, α2, and α3. You can change the angle of rotation of.

As shown in FIG. 4 described above, the angle α in the rotation direction of the annular rotating body of each wheel type direction changing device is basically the same angle for each shaft shaft unit, but as shown in FIG. 7 above, the angle α is the same. By changing the fixing angle of the fixed portion of the rotating body 214 of 3 with respect to the shaft shaft, the rotation direction angle α becomes variable even for the same shaft shaft unit. This means that the angle α in the rotation direction of the annular rotating body of all the wheel type direction changers is variable.

Not limited to. That is, it is also possible to set the shaft axial direction substantially parallel to the traveling direction of the conveyor. In particular, in the narrow belt type conveyor and the roller type conveyor shown in FIG. 1, it is possible to set the axial direction of the shaft shaft unit of the wheel type direction changing device in parallel with the conveyor traveling direction.

As described above, in the wheel type direction changing device according to the embodiment of the present invention that forms the merging point 203 in the merging and transporting of articles of the conveyor, the rotation direction of each annular rotating body configured in a plurality of stages is arbitrarily set. Moreover, the amount of protrusion from the upper surface of the conveyor can be arbitrarily set. That is, it relates to one embodiment of the present invention regardless of the angle at which the original conveyor 202 that merges merges with the main conveyor 201, and regardless of the size of the article that is conveyed. The wheel type direction changer can arbitrarily set all the annular rotating bodies to the rotation direction and the protrusion amount at which the merging direction conversion is most likely to be performed, so that it is safe without giving an impact to the merging articles. Allows smooth combined transportation.

Although the detailed embodiment of the wheel type direction changing device of the present invention has been described above in one embodiment of the conveyor belt merging, it goes without saying that the wheel type direction changing device can be used not only at the merging but also at the branching or at the crossing. Further, the transfer conveyor is not limited to the narrow belt type conveyor and the roller type conveyor, and it is sufficient if there is a space where the annular rotating body of the wheel type direction changing device can protrude on the conveyor. These are within the scope of this technical idea in any form.

At today's product delivery bases, the amount of objects to be transported has increased, the shapes and forms have diversified, and speeding up is desired, but on the other hand, consideration is required to be gentle on the objects to be transported so that impact and acceleration are not applied. To. The wheel-type direction changing device according to the present invention can be applied to various places in physical distribution and transports because it is possible to significantly reduce the impact force that causes great damage as the transport speed is faster, especially in the merging and sorting of articles. It greatly contributes to gentle and smooth transportation of objects. It can also be used in various industries. According to the invention according to the present application, a wheel-type directional change device capable of significantly improving the safety and work efficiency of the transported article while also significantly improving the economic efficiency is realized.
