[Conventional technology]

Japanese Patent Application Laid-Open Publication No.
57-93804, JP-A-60-248503, JP-A-6
The thing etc. which are described in the 1-226 publication are known.

A brief description of the description of the above publication is found in JP-A-57-93804.
In the publication, a rotatably supported roller is arranged at an appropriate interval along a slope inclined in a direction orthogonal to the axial direction, and the rotation of a suitable roller located at the lower end of the slope is braked. A roller conveyor is provided which is provided with braking means.

Further, Japanese Patent Application Laid-Open No. 60-248503 discloses a flow rack device provided with an article cutting device and an article braking device interlocked with the cutting device on the exit side of the flow rack.

Further, JP-A-61-2612 discloses that the load conveyed from the conveyer conveyor is conveyed by the primary sorting conveyer to be primary sorted and transferred to a plurality of primary storage conveyors, and the sorted load is stored in each primary storage conveyor. Take out to the primary circulation conveyor in a conveyor unit, and pass it to the secondary sorting conveyor that is arranged in parallel either above or below the primary sorting conveyor, and carry out secondary sorting while transporting on this secondary sorting conveyor The sorting method is described in which after passing the load to the storage conveyor and taking out the secondary sorted load to the secondary side circulation conveyor in each secondary storage conveyor unit, it is conveyed to the loading section to the truck. It is described that a conveyor, a gravity roller conveyor or the like can be appropriately adopted.

Also, as Japanese Utility Model Publication No. 52-37574, a brake device is provided in the middle of a free roller conveyor, and the brake device is used to decelerate the articles accelerated by the free roller conveyor to convey them to a desired location. Device technology is disclosed.

[Problems to be solved by the invention]

However, there are the following problems in the above-described article loader and loader.

That is, in JP-A-57-93804, since the braking means is arranged at the lower end of the inclined conveyor, it is necessary to strongly elastically contact the roller with the braking means in order to obtain the braking effect. Even if the container case at the bottom end is taken out, the braking state of the container case on the upstream side is not released, and it is difficult to convey the article toward the bottom end at a desired speed.

Further, in JP-A-60-248503, the article may be damaged because the brake device acts directly on the article, and the article is removed from the inclined conveyor because the brake apparatus is linked to the article cutting device. The brake device was intermittently operated during delivery, and the article could not be delivered continuously at high speed.

Further, in JP-A-61-2612, there is a description that a gravity roller conveyor or the like can be appropriately adopted as a storage conveyor, but there is no specific description, and if the gravity roller conveyor is not provided with a brake device or the like, it is used. In that case, the article collides with a stopper provided at the lower end with a large force, and the article is damaged.

Further, in Japanese Utility Model Publication No. 52-37574, the gradient of the free roller conveyor is increased, and a brake device is provided in the middle of the free roller conveyor to decelerate the speed so that the article is conveyed to the destination without any stagnation. Therefore, it is not suitable for an apparatus that requires a certain amount of articles to be stagnated on a conveyor for load balancing. In particular, no consideration was given to articles that are light in weight and difficult to run on a conveyor and tend to stagnate.

The present invention solves these problems by making it possible to lengthen the loading line, moving the article at high speed on the upstream side of the loading line, and slowly delivering it on the downstream side. Even if it stagnates on the upstream side, goods can be transported slowly downstream, it does not damage the goods, it can be controlled according to the load-sorting command, it is inexpensive overall, and the load-sorting can be done efficiently It is an object of the present invention to provide a loading and unloading device.

[Means for solving problems]

The present invention is provided with an inclined conveyor for performing load adjustment. During the load adjustment at the downstream end of the inclination conveyor, articles are sequentially retained on the inclination conveyor from the downstream side, and when the load adjustment is completed, the articles are inclined conveyor. A discharging device for discharging from the downstream end of the article is provided, and the inclined conveyor is provided with a roller rotatably supported for placing an article so as to be orthogonal to the flow direction of the conveyor, thereby stopping the article flow. In the article arranging device including a means for causing the stopping means, the stopping means is provided at an intermediate portion of the convey path of the conveyor, and a braking device for braking rotation of a plurality of rollers at the intermediate portion, A driving device for driving the braking device and a control device for electrically controlling the driving device are provided, and a pull-in conveyor for pushing down an article on the inclined conveyor is provided on the upstream side of the inclined conveyor, and the control is performed. The device is
When loading the articles on the inclined conveyor, the braking device is brought into a braking state, and when discharging the loaded articles from the downstream end of the inclined conveyor, the discharging operation of the dispensing device is performed. It is characterized in that it includes means for simultaneously releasing brakes in conjunction with each other.

The braking device preferably includes a braking plate that simultaneously brakes the rotation of a plurality of adjacent rollers in the middle portion.

It is preferable that the control device is configured to be controlled by a computer that controls a higher-order load arrangement.

[Action]

The conveyor is an inclined conveyor having a large number of rotatable rollers, and the rotation of the rollers is braked in the middle of the inclined conveyor. As a result, the article stagnates at this intermediate portion. By releasing the braking, the articles can be delivered slowly.

Further, when the articles are to be sorted on the inclined conveyor, the braking device is brought into a braking state to sort the articles on the conveyor. When the loading is completed, the braking is released all at once, and the articles are discharged from the downstream side of the inclined conveyor by the discharging device.

In this way, since the braking force is not directly applied to the articles, the articles are not damaged and the articles can be loaded regardless of the self-propelledness of the articles. In addition, it is possible to efficiently load and unload by using a long inclined conveyor.

Since the braking device is controlled by the electric signal of the control device, it can be controlled by a command from the host device.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a vertical sectional view of an embodiment of the present invention. In FIG. 1, branch conveyors 1 and 1'installed in upper and lower two layers.
Thus, the sorted articles are placed by the pull-in conveyors 2 and 2'on a loading line composed of two upper and lower inclined conveyors. At the downstream ends of the flow of articles in the load-and-sort line, there are delivery devices 5 and 5 ', and articles are cut out to the conveyors 6 and 6', and one end of which is vertically moved up and down.
The articles are loaded into a container (not shown) via the.

The delivery devices 5 and 5'are provided at the downstream ends of the roller conveyors 3 and 3'of the load-aligning line, and are provided with stoppers and actuators as shown in FIG.
During loading, the stoppers cause the articles flowing down the roller conveyors 3 and 3'to stay on the roller conveyors 3 and 3'in order from the downstream end. When the loading is completed, the dispensing devices 5 and 5'release the stoppers to discharge the articles accumulated on the roller conveyors 3 and 3'to the transport conveyors 6 and 6 '.

FIG. 2 is a detailed view of part A shown in FIG.

Here, the feature of the present invention is that the braking devices 4 and 4'are arranged in the intermediate portion A of the conveying path of the long inclined roller conveyors 3 and 3'provided on the loading line. is there. This braking device has a rubber-lined braking plate 9 for braking the roller 8 in the middle portion as shown in FIG.
including. The driving device for driving the braking plate 9 to the position shown by the broken line includes an actuator 10 installed on the braking device mounting frame 11 and an electromagnetic valve 13 for sending pressure air to the actuator 10 via a pipe 12A and a hose 12B. Including. The control device for controlling the drive device includes a computer 14 for controlling the upper-order load assembling and a control circuit 16 for receiving the control command via the input / output interface 15 and sending an electric signal.

Further, the articles placed on the upstream position of the portion A where the braking devices 4 and 4'of the roller conveyors 3 and 3'are located are accelerated by self-propelling because the section of the inclined rollers is long. Further, even in the case of articles that are difficult to move by themselves, when articles are continuously placed, the articles are pushed out downstream by the driving force of the pull-in conveyors 2 and 2'provided upstream of the roller conveyors 3 and 3 '.

Even if there are some differences in the number of lots of various kinds of articles, in order to efficiently load the articles, the lengths of the roller conveyors 3 and 3'of the loading line should be increased. Moreover, it is necessary to increase the delivery speed of the articles on the pull-in conveyors 2 and 2'to 20 m / min or more, preferably about 60 m / min.

FIG. 3 is an explanatory view of the operation of loading articles according to the present invention. In FIG. 3, by the pull-in conveyor 2, the articles sent to the roller conveyor 3 are self-propelled by the component force of their own weight due to the inclination, and proceed to the downstream side while accelerating. The article is braked at the braking device 4 in the middle of the roller conveyor 3. If the number of self-propelled articles is small, the articles are stagnant on the upstream side of the braking device 4. However, when articles are further fed from the upstream side, braking is applied by the component force of the self-weight of many articles. The article slips and passes over the roller 8. In this case, the articles slowly reach the dispensing device 5.

In the case of articles that are difficult to self-propell, for example, articles having a large volume and a light weight, there may be a large number of stagnations on the upstream side of the braking device 4. For example, the articles arrive at the dispensing device 5 because they are sequentially pushed downstream by the driving force of the drawing conveyor.

When a plurality of roller conveyors 3 and 3'are provided, braking of all lines is completed when all branch load adjustments are completed and line-by-line cutting is started by the respective pay-out devices 5 and 5 '. To release. That is, since the simultaneous operation is performed, one solenoid valve 13 may be provided for each of the upper and lower two layers.

Note that each line may be released, and in this case, an electromagnetic valve may be provided for each line.

If you release the braking on all lines at once, the articles stagnant on all the lines will start at the same time and the impact will increase, so by repeating the on / off operation of the solenoid valve for a short time, the rollers of the braking part gradually Can be rotated. In this way, each line starts quietly and individually, so there is little impact.

These input the day-to-day loading program to the host computer 14 and send the command to the input / output interface 15.
Is given to the control circuit 16 via.

In this way, articles of 3000 cases / hour or more can be loaded very easily without damage.

[Effect of device]

According to the present invention, an article aligning device having a sufficiently long length can be installed in the article aligning apparatus, and the article can be moved at a high speed upstream of the article aligning line and on the downstream side. Since it can be delivered slowly, the articles are not damaged even when the articles are loaded at a high speed. Also,
Since a pull-in conveyor is provided on the upstream side of the inclined conveyor to prevent stagnation of articles or the like that are difficult to move by themselves, it is possible to efficiently load and unload the articles.

When arranging items, the braking device is used for arranging, and when the arranging process is completed, the braking devices can be released all at once and the product can be paid out. It is possible to perform various controls, shorten the time for cutting out the articles, and load a large number of articles in a short time. Further, there is an effect that the article sorting device can be installed at low cost.
