  The present invention belongs to the technical field of a reverse running prevention stopper device that prevents reverse running of an article to be conveyed that moves on a wheel conveyor, and more particularly relates to a reverse running prevention stopper device that can be detachably attached to a wheel conveyor. .

2. Description of the Related Art Conventionally, in various manufacturing sites, a fluid shelf is used in which a shelf surface is configured by a plurality of wheel conveyors that are inclined at an angle at which an article to be conveyed (hereinafter simply referred to as an article) is moved by the action of gravity. When the goods are input from the input side, this fluid shelf will self-propel to the take-out side due to its own weight and inclination, and each article will be stored in a chain, so that it will be supplied to the workers sequentially. It is effective for.
In order to take out an article from such a fluid shelf on the take-out side, it is necessary to push back the article in the upper part of the daisy chain in the backward direction and then take out the target article. At this time, sometimes there is a surplus force, and the article on the shelf is caused to run backward in the backward direction and fall from the loading side. Further, in the event of an earthquake, there is a risk that the article will be sent back from the input side and jumped out and dropped. Therefore, in order to prevent such an accidental drop of the article due to reverse running, a reverse running prevention stopper device described in Patent Document 1 below is known.

As shown in FIGS. 7A and 7B, the reverse running prevention stopper device 70 of Patent Document 1 is disposed between the wheels 72 of the wheel conveyor 71. The stopper device 70 has a stopper member 70a protruding on the movement path (line) of the article G, the stopper member 70a is rotatable, and the stopper member 70a falls down only in the movement direction of the article G, and moves backward. Is composed of a support material 70b that supports the standing state so as to be held. The stopper member 70a and the support member 70b are connected by a spring material 73 provided at a position where the stopper member 70a stands up. When the article G moves in the arrow direction (forward direction) and hits the stopper member 70a. Then, it is tilted in the same direction against the force of the spring (see FIG. 7A). However, when the article G passes, the stopper member 70a is immediately returned to the original standing state by the force of the spring (see FIG. 7B). When the article G moves in the backward direction and hits the stopper member 70a, the stopper member 70a hits the upper portion of the support member 70b and is restricted from rotating in the backward direction, so that the backward movement of the article G can be reliably prevented.
The reverse running prevention stopper device 70 is attached to the wheel conveyor 71 by bolting the bottom surface of the wheel conveyor 71 with a stay 74 connected to the lower end of the support member 70b as shown in the figure.

Embodiments of a reverse running prevention stopper device according to the present invention will be described below with reference to the drawings.
FIG. 1 shows an end portion on the input side E of each wheel conveyer 2... Constituting a shelf by installing the reverse running prevention stopper device 4 of the present invention on the beam members 11 and 11 constituting the frame 10 of the fluid shelf 1. The example attached to was shown.
Each wheel conveyor 2 is self-propelled from the input side E to the extraction side D by the action of gravity between the beam members 11 and 11 before and after the fluid shelf 1 by means of the mounting brackets 3 and 3 attached to both ends thereof. It is erected in an inclined state. Incidentally, the mounting bracket 3 is a bracket for laying a commonly used wheel conveyor 2 on the beam members 11, 11. Specifically, as shown in FIGS. 3A and 3B, an arch that can be mounted on the beam member 11. It is comprised from the beam material receiving part 30 of a type | mold, and the rail part 31 and the lip | rip part 32 which are inserted in the wheel conveyor 2. FIG.

Next, a specific configuration of the reverse running prevention stopper device 4 (hereinafter simply referred to as a stopper device) of the present invention is shown in FIG. 2, and the procedure for attaching and fixing the reverse running prevention stopper device 4 to the wheel conveyor 2 is shown in FIG. This is shown in FIG.
The stopper device 4 includes a stopper member 5 that stands on a moving path of the article, and an L-shaped support member 6 that rotatably supports the stopper member 5.
The stopper member 5 has a center of gravity below a support position by the support member 6 and is configured to hold an upright state by its own weight.
The support member 6 is composed of a fixed portion 60 formed in a shape and size that can be inserted and attached to an end portion of the wheel conveyor 2 described later, and a horizontal portion 61 joined to the stopper member 5. Yes. The fixing portion 60 is formed with cut grooves 60a and 60a formed at a size and position where the lip portions 32 and 32 (see FIGS. 3A and 3B) of the mounting bracket 3 can be fitted. The cut groove 60a is preferably cut sufficiently large so as to correspond to the lip portion 32 of the mounting bracket 3 having various thicknesses. Moreover, it is good also as a shape not less than the width | variety of the lip | rip part 32 but notched over the full length of the horizontal part 61. FIG.

  The support member 6 rotatably supports the stopper member 5 by a hinge portion 7. That is, it is seen in a plan view that is connected to the inner center portion of the stopper member 5 from two axial ends of the support pipes 50, 50 provided in a concave shape when seen in a plan view and the end of the horizontal portion 61 of the support member 6. Are aligned with the axis of the convex support pipe 61a, and are pivotally supported by pivot pins 8 inserted into the pipes 50 and 60a. When the stopper member 5 is in the standing state, the support member 6 is horizontally It is supported so as to be substantially perpendicular to the portion 61. In the support state shown in FIG. 2, the stopper member 5 rotates both in the forward direction and in the backward direction of the article. However, when the stopper device 4 is attached to the end of the wheel conveyor 2, the stopper member 5 moves in the backward direction. Is controlled by the beam member 11 on which the wheel conveyor 2 is installed, and the standing state is maintained (see FIG. 4).

  As shown in FIGS. 3A and 3B, the stopper device 4 configured as described above is first inserted into the rail portion 31 from the opening of the mounting bracket 3. That is, the cut grooves 60 a and 60 a of the support member 6 constituting the stopper device 4 are fitted into the lip portion 32 of the mounting bracket 3 and inserted into the rail portion 31.

  When the mounting bracket 3 having the stopper device 4 inserted therein as described above is inserted deeply into the wheel conveyor 2 having a length that fits between the beams 11 and 11, the wheel conveyor 2 that the mounting bracket 3 originally has. The outer surface of the fixing part 60 of the stopper device 4 and the end of the wheel conveyor 2 are brought into close contact with each other by the fixing force to the stopper device 4, and the stopper device 4 is firmly attached and fixed to the wheel conveyor 2 (see FIG. 4).

Next, about the operation | movement of the stopper apparatus 4 when the wheel conveyor 2 which fixed the stopper apparatus 4 as mentioned above is constructed between the beam materials 11 and 11 of the flow shelf 1 shown in FIG. This will be described with reference to FIG.
First, as shown in FIG. 5A, when the article G moves from the loading side E and hits the stopper member 5, the stopper member 5 rotates in the forward direction and falls down, and the article G is guided onto the wheel conveyor 2 and taken out. Self-run toward side D. After the article G passes over the stopper member 5, the stopper member 5 immediately returns to the standing state by its own weight (FIG. 5B).
When the articles G are continuous and full on the wheel conveyor 2 and the lowermost article G is taken out from the take-out side D, the upper article G is once pushed backward (injection side E). When the force G is applied in the backward direction), the article G closest to the loading side E advances in the backward direction and hits the inner surface of the stopper member 5 (see the dotted line portion in FIG. 5B). 3 is prevented from rotating beyond the standing state when it hits the beam member receiving portion 30 or the beam member 11, so that the standing state of the stopper member 5 is reliably maintained. Therefore, the reverse movement of the article G in the backward direction can be stopped, and an accident where the article G falls can be prevented.

The reverse running prevention stopper device 4 of the present invention is not limited to the first embodiment.
That is, in the stopper device 4 of the first embodiment, the support member 6 supports the stopper member 5 so that the stopper member 5 can be rotated by about 360 °. The lower end of the contacted with the beam material 11 does not rotate beyond the standing state. However, in the shapes of the wheel conveyor and the mounting bracket, there are cases where the stopper member 5 does not hit the beam member 11 or cannot be reliably regulated. The second embodiment is a stopper device 9 corresponding to such a case. The basic configuration is the same as that of the first embodiment, and the difference will be mainly described below.

  The support member 90 of the stopper device 9 is joined to the support member 90 so that the stopper member 91 can rotate freely, the stopper member 91 falls down only in the forward direction of the article, and can hold an upright state in the backward direction. It is configured.

  Specifically, as shown in FIGS. 6A and 6B, support pipes 91 a and 91 a provided at two locations in the inner middle portion of the stopper member 91 are arranged to protrude above the horizontal portion 90 a of the support member 90. The support pipe 90b connected from the end of the horizontal portion 90a and protruding in the same manner is aligned with its axis, and a pivot pin 92 is inserted into both pipes 91a and 90b so as to be supported rotatably. .

  Therefore, as shown in FIG. 6B, even if a force in the backward direction is applied to the stopper member 91 and a clockwise turning force is applied, the side surface R (or plate thickness) of the horizontal portion 90a of the support member 90 is also referred to. ) Sufficiently resists the same power, so it will not fall down in the direction of retraction. Therefore, it is possible to prevent the article from running backward without hitting the beam 11.

  Although the embodiments have been described with reference to the drawings, the present invention is not limited to the illustrated examples, and includes a range of design changes and application variations that are usually made by those skilled in the art without departing from the technical idea thereof. I will add that just in case. For example, the reverse running prevention stopper devices 4 and 9 are fixed to the wheel conveyor 2 via the mounting bracket 3. However, the present invention is not limited to this, and the stopper devices 4 and 9 are directly connected to the end of the wheel conveyor 2. It may be fixed. In this case, the cut groove 60a of the fixing portion 60 of the stopper device 4 (including the stopper device 9) is fitted and fixed to the lip portion of the wheel conveyor 2.
