Description

[Detailed Description of the Invention] [Purpose of the Invention] (Industrial Application Field) The present invention relates to a carrying-in device that carries objects to be carried into a moving carrier.

(Prior art) When a newspaper company wraps printed newspapers into predetermined numbers and automatically distributes them to stores or other destinations, for example, they wrap printed newspapers in an endless manner on an endless rail. A system is used in which a large number of connected trolleys are circulated, the doors are opened to each trolley at the loading section, and newspaper bundles are carried in, and the doors are opened and taken out from each trolley at each destination-specific loading section. There is.

In the case of such a system, due to the nature of newspapers, speedy distributing work is required, so the system is operated at high speed and each trolley travels at high speed. It is required to quickly and reliably transport newspaper bundles to each trolley, and transport devices for this purpose have been proposed in the past.

(Problem to be solved by the invention) However, no matter how precise a loading device is used, it is almost impossible in reality to completely eliminate failures in loading newspaper bundles to the trolley. However, if the newspaper bundles are brought in incompletely, the newspaper bundles moving with the trolley may damage the loading device or the trolley, or the entire system including them may stop. In particular, if the stopper or guide that regulates the position of the newspaper stack on the loading device is located close to the cart and on the downstream side in the direction of movement of the cart, the above-mentioned problems may occur. There is a possibility of damage or suspension due to complete delivery.

The present invention was developed in view of these points, and is designed to prevent damage to the loading device and the conveyor due to incomplete loading of a loading device that loads articles such as bundles of newspapers onto a moving conveyor such as a trolley. This is to prevent

Further, a movable stopper 72 is provided facing the front end of the first conveyor 12 and located on the side of the front end of the third conveyor 51.
This stopper 72 is pivotally supported by the frame 11 via a support shaft 73 at the end on the third conveyor 51 side, and has an arm 74 projecting downward, and a base at the tip of the arm 74. The tip of a piston rod 76 of an air cylinder 75 is pivoted to the frame 11. The stopper 72 is always biased counterclockwise in FIG. 3, that is, in the upward direction, by the air cylinder 75, and a relief valve, which is customary in fluid pressure operating systems, is connected to the air circuit of the air cylinder 75. We are prepared.

Further, a stopper 77 is provided above the front end of the second conveyor 31.

Next, the carrying-in operation in the carrying-in device 6 will be explained.

In the carrying-in device 6, the roller conveyor 14 of the first conveyor 12 and the second conveyor 31 are constantly driven and rotated by a motor 22 and a motor 50, respectively, and are connected to first and second electromagnetic clutches 65, 66. motor 6
2 Constantly driven.

In this state, the object to be conveyed is sent to the roller 1
7 and 18 onto the belt conveyor 13 of the first conveyor 12, the conveyed object is fed on the belt 16 and transferred onto the roller conveyor 14, and further fed by the rollers 20 to the stopper 7.
2, the detector detects the conveyed object, and the air cylinder 26 is actuated to lower the roller conveyor 14, and the conveyed object is transferred from above the rollers 20 to the belt conveyor 32 of the second conveyor 31. At the same time, the conveyed object is transferred to the belt conveyor 32 along the stopper 72 and transferred to the belt 36.
is sent to an elevating belt conveyor 33. Note that when the conveyed object on the belt conveyor 32 is transferred to the elevating belt conveyor 33, the air cylinder 2
6 is activated, and the roller conveyor 14 returns to its upward position. Next, the conveyed object on the elevating belt conveyor 33 is sent over the belt 40 to the stopper 77.
At the same time, the detector detects the conveyed object, and the air cylinder 46 is actuated to lower the conveyor table 37 and move the conveyed object from the top of the belt 40 to the third conveyor.
At the same time, the conveyor table 37 is stopped at the lowered position and stands by.

In this standby state, each trolley 5 approaching the loading section 3
When the detector detects an empty cart 5, the first and second electromagnetic clutches 65 and 66 are actuated simultaneously, and the motor 62 is connected to each sprocket wheel 67, chain 68, and each gear via the first electromagnetic clutch 65. 69 transmits rotational force to the pulley 53, and also transmits rotational force from the motor 62 to each sprocket wheel 70 and chain 7 via a second electromagnetic clutch 66.
1 transmits rotational force to the disk 60. As a result, the belt 54 and the locking body 55 move forward instantaneously, and the pusher 56 moves back and forth instantaneously in synchronization with the locking body 55. ), regardless of whether it is high or low (thick or thin), the pusher 56 and the locking body 55 ensure that the belt 54 is accelerated from a resting state reliably and instantaneously without falling backward or slipping. Then, after the pusher 56 advances a predetermined distance and begins to retreat, the object to be conveyed is moved forward by the belt 54 while being held by the locking body 55, and is thrown into the trolley 5.

The first electromagnetic clutch 65 is turned off after the belt 54 has rotated a predetermined distance, for example, half the length of the belt 54, and the second electromagnetic clutch 66 is turned off after the disk 60 has rotated, for example, once. Then, the air cylinder 46 is activated, and the conveyor table 37 is raised and stopped, waiting for the next conveyed object.

Further, the third conveyor 51 may not be able to fully carry the object into the cart 5 for some reason, and the object may be pushed by the moving cart 5 and pulled against the end of the movable stopper 72. Hanging, stopper 7
2 or rides on the stopper 72, the air cylinder 75 of the stopper 72 is moved due to the load.
As the air pressure increases, the relief valve of the air circuit releases the pressure, and the stopper 72 moves clockwise around the support shaft 73, that is, in the clockwise direction in FIG. It rotates in the downward direction, thereby preventing the transported object from interfering with the movement of the transported object and preventing the transported object from getting caught between the carry-in device 6 and the cart 5 and damaging the cart 5 and the carrying device 6. The transport device 1 is not stopped.

[Effect of idea]

According to the present invention, the article to be conveyed, such as a bundle of newspapers, supplied on the first conveyor of the carrying-in device is sent to the third conveyor via the second conveyor, and is pushed in synchronization with the third conveyor. Since the conveyor is activated to push the conveyed object, it is possible to instantaneously and reliably accelerate the conveyed object, and therefore the conveyed object can be quickly and reliably transferred to a conveyor such as a trolley. In addition, a stopper facing the front end of the first conveyor and located on the side of the front end of the third conveyor is formed to be movable up and down, so that objects that have not been completely carried into the conveyor can be moved along with the conveyor. If the object moves and gets caught on the stopper, the stopper is lowered, so even if the object to be transported is not fully loaded into the transporter, there is no risk of damage to the transporter or loading device, and these can be easily moved. There is no need to stop the entire system that includes it.
