Abstract

(57) [Summary] (Corrected) [Purpose] To provide a stopper at the conveyor end that prevents the load from bouncing and allows smooth transfer to the next conveyor. [Structure] Since the mounting plate 9 is erected on the terminal plate 7 of the first conveyor 1 and the slide plate 12 with the cushioning material 11 is established on the mounting plate 9, the load is rebounded at the terminal of the conveyor. In addition, it can be smoothly transferred to the next conveyor.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stopper for preventing a bouncing of a load at the end of the conveyor and smoothly transferring the load to the next conveyor when the load is conveyed at a right angle by, for example, both roller conveyors orthogonal to each other.

[0002]

[Prior art]

 In the roller conveyor, the means for conveying the load at a right angle was to use a method of bending the key points of one conveyor in an arc shape and two roller conveyors that were orthogonal to each other. The load was stopped at the end of the first conveyor. After that, there is a method of automatically sending it to the second conveyor, which is orthogonal to each other. Both methods are implemented depending on the contents of the load, the purpose of its transportation, and the situation of the installation location.

In the case of the latter method, conventionally, a plate-shaped stopper was erected at the end of the first conveyor to temporarily stop the load.

[0004]

[Problems to be solved by the device]

 However, according to the conventional plate-shaped stopper, when the load conveyed by the first conveyor hits the stopper and is bounced back, if the load is large, a part of the load is conveyed to the conveyance path of the second conveyor. It may become more outward and may be difficult to feed into the second conveyor.

Further, the exterior of the load and a part of the contents may be damaged by the impact.

An object of the present invention is to solve the above problems by providing a stopper with a buffering property.

[0007]

Means for Solving the Problems A conveyor stopper of the present invention comprises a mounting plate standing upright at a crossing position of a plurality of conveyors having different transfer directions, the mounting plate standing on a surface facing the load. A feature is that a cushioning material is attached and a flexible sliding plate is attached on the surface of the cushioning material.

[0008]

[Action]

 The cushioning material of the stopper prevents the bounce of the load, and the sliding plate allows the load to slide laterally against the surface.

[0009]

【Example】

 The drawing shows a roller conveyor using the stopper according to the present invention. The right end of the terminal part of the first conveyor (1) (the lower part of FIG. 1) has a base end of a second conveyor (2) having an equal height. Are orthogonal.

(3) is a roller, below which a drive shaft (4) which is rotated by a motor (not shown) and which faces the conveying direction is pivotally provided, and below the roller (3) on the drive shaft (4). An annular belt (6) is wound around the pulley (5) and the roller (3) fitted to the roller, and the rollers (3) of the first and second conveyors (1) and (2) are in the same direction. Rotate at a constant speed.

Only the three rollers (3 ′) of the end plate of the first conveyor (1) have the belt (6) omitted.

At the end (7) of the first conveyor (1), a mounting plate (9) of the stopper (8) of the present invention, which has a horizontal width substantially equal to that of the roller (3) and is directed upward, is attached to the bolt (10). ).

A soft rubber plate, sponge, felt or other cushioning material (11) is attached to the front surface of the mounting plate (9), and the cushioning material (11) has a surface such as a polyethylene plate. A flexible sliding plate (12) is attached.

On the lower surface of the end portion of the first conveyor (1), there is installed a lateral feeding device (13) which moves up and down slightly as described later.

The pair of sprockets (15) rotated by the reduction motor (14) installed in the transverse feed device (13) have a pair of endless chains (16) parallel to each other in the shape of a downward triangle. The lower part of is hung around and runs in the direction of the arrow. (17) is a guide plate.

The two endless chains (16) are respectively located between the terminal and the roller (3) that is second from the terminal and between the fourth roller (3) and the roller (3) that is fourth from the terminal. It is located slightly below the upper end of (3).

As shown in FIG. 1, the roller conveyor described above is flexible when the load (18) conveyed in the direction of the arrow by the first conveyor (1) collides with the stopper (8) of the present invention. The flexible sliding plate (12) and the cushioning material (11) absorb the shock of the load (18), and due to the cushioning action, the load (18) does not almost bounce and the load (18 ) Also has its posture corrected as shown by the imaginary line, and stops in contact with the sliding plate (12).

Then, a micro switch (not shown) provided in the stopper (8) is activated by the impact of the load (18), and the upper side of the endless chain (16) together with the lateral feed device (13) is moved to the position shown in FIG. As indicated by the imaginary line in Figure 3, raise the load (18) by raising it slightly above the upper end of the roller (3).

Next, the endless chain (16) runs in the direction of the arrow, and the load (18) transferred onto the second conveyor (2) is conveyed in the direction of the arrow.

At this time, even if the load (18) is in close contact with the stopper (8), it is smoothly transferred onto the second conveyor (2) by the action of the sliding plate (12).

When the load (18) is completely transferred, the traverse device automatically stops the rotation of the endless chain (16) and descends to the standby position.

As a modification of the sliding plate 12, the sliding plate 12 may be a rigid plate. In this embodiment, the roller conveyor is horizontal and each roller (3) rotated by the drive of the drive shaft (4) conveys the load (18), but the load (18) is placed on the inclined roller conveyor. The stopper (8) of the present invention has the same effect as described above even when the vehicle is driven by its own weight.

Although not shown, in a rotary rack that is directly connected to a production line of a factory and temporarily stores and supplies various kinds of works and members, a roller conveyor for transferring trays is temporarily stopped. It can also be used effectively as a station for placing and removing workpieces in and from the tray.

[0024]

[Effect of device]

 In the stopper of the present invention, the cushioning material prevents the load from bouncing back and the sliding plate facilitates the lateral movement of the load contacting the surface thereof, so that the load etc. is prevented at the intersection of the two roller conveyors which are orthogonal to each other. It can be safely stopped while in contact with the stopper to smoothly and surely change the transport direction.

Moreover, the stopper of the present invention is inexpensive and can be easily attached to an existing roller conveyor.
