[Industrial applications]

 This invention relates to an inclined belt accumulation conveyor.

[0002]

[Prior art]

 The main form of an accumulating conveyor is that whose conveying means is composed of rollers, wheels, etc., and the means for accumulating this is mainly the means for braking the rollers or wheels. Techniques for accumulating means for braking or stopping by disconnecting the contact-related configuration are disclosed in, for example, Japanese Utility Model Publication No. 50-37665, Japanese Utility Model Publication No. 50-74689, Japanese Patent Publication No. 53-8437, Japanese Patent Publication No. 52-133682, and Japanese Patent Publication No. 52-133682. There is a technology disclosed by Japanese Patent Laid-Open No. 58-59119.

[Problems to be solved by the device]

 Although each of the disclosed technologies has its own structure and its effect for attaining its purpose, in the accumulation conveyor based on the inclined conveyor as the invention of the present application, The rollers or wheels used in the transportation means disclosed in the published gazette have a small coefficient of friction for the purpose of an inclined conveyor, and therefore, the transportation, the control, and the static action are suppressed. I am dissatisfied with the dislike of not achieving my goals.

In order to eliminate the above-mentioned disadvantages of the prior art, a belt having a large coefficient of friction is used as the conveying means, and a plate having a surface structure having a large coefficient of friction is provided at a position sandwiching the belt, and the belt is accumulated to move up and down. The object of the present invention is to cut off the carrying action of the transported object so that the stopping action can be obtained by the plate.

[Means for Solving the Problems]

As a means for achieving the above object, the present invention installs an endless belt inside two conveyor frames installed parallel to each other with a desired set width dimension and inclined. Then, the plates are installed parallel to each other at positions on both sides of the entire length of the working forward path surface of the belt, and at a position lower than the working forward path surface during the operation for the purpose of transporting the goods by the belt. In order to make contact with the lower surface of the full length of the forward path, slider beds divided into a plurality of pieces each having the desired total length are arranged in a straight line, and actuators are provided on the lower surface of each slider bed. , The sensor that activates the actuator is placed near the rear end of the previous slider bed in each slider bed, and at the leading edge of the conveyor. In addition to providing a topper, when accumulating the slider bed next positioned by each sensor, the position of the forward path of the belt is lowered to a position lower than the plate positions on both sides, and the load is placed on the plate for driving. It is configured so that it can be separated.

[Action]

In the inclined belt accumulation conveyor according to the present invention, when a conveyed product is carried on a driven belt, the conveyed product is conveyed up to a stopper at the tip of the conveyor, where it is stopped and then The transported goods are stopped one after another at the top position of the most advanced slider bed, and when the number reaches a certain number, a sensor installed at the rear end of the slider bed will be installed on the bottom surface of the slider bed in the rear row if it catches the transported material for a certain time. Actuating the switching valve of the actuator to discharge the air inside the actuator, lower the slider bed and belt from the plate position, place the load on the plate, and stop the transfer.

Therefore, in the one zone of the slider bed which is linearly positioned on the lower surface of the belt, when the transported material stops near the final end for a certain period of time or more, the sensor catches it and the slider bed that is continuously connected next. The actuator on the underside of the robot is contracted to place the load on the plate and the transport is stopped.However, the subsequent load is advanced by the belt drive and slides down the plate of the slider bed to move forward. However, when a certain amount of cargo is cascaded in the zone and the sensor catches the cargo at the final end, the actuator in the next zone is actuated to stop the transportation.

[0008] When the transported material at the final end of the one zone located on the front slider bed moves and the sensor cannot catch, the switching valve operates and air is sent from the pump to expand the actuator and the slider bed together with the belt. It raises it from the position of the plate and starts the transportation again.

When the slider bed moves up, the link rotates clockwise in the figure, but the link comes into contact with the pin and does not rotate any more, so that the rising of the slider bed can be restricted.

Further, by attaching a plate material having a large friction coefficient to the upper surface of the plate and providing it on the entire surface by tacking or the like, the plate can be used with an inclination angle equivalent to that of a normal belt conveyor, and the plate itself can be used. It is not necessary to provide another plate material as described above when performing processing for increasing the friction coefficient over the entire length of the upper surface.

According to the present invention, as described above, when the transported object is loaded to the rear end of the front slider bed, the transported object on the subsequent slider bed can be placed on the plate. When the slider bed at the front is released, it can be transported again.However, since it is possible to accumulate the conveyor that is transported by the belt, it is possible to transport the goods while the conveyor is tilted. Line pressure is not generated because it can be accumulated and placed on the plate so that it can be stopped without slipping even in an inclined state.

【Example】

Next, an embodiment of the present invention will be described with reference to the drawings. Inside the two conveyor frames 1 and 1 ′ installed in parallel and inclined with a desired set width dimension, endless The belts 2 are installed, and the belts 2 are arranged at positions on both sides of the entire length of the working forward surface of the belt 2 at a position lower than the working forward surface when the object A is moved by the belt 2. 3 and 3'are installed in parallel, and a plurality of objects to be conveyed (five in the figure) are placed with a width sufficient for the belt 2 to contact the lower surface of the full length of the working forward path of the belt 2.
