Description

  The present invention relates to a distribution shelf device, and for example, relates to a distribution shelf device used for an operator to take out an electrical component packed in a box in an assembly factory for electrical products and perform a predetermined assembly operation.

  Conventionally, as a distribution shelf device, for example, an assembly operator takes out electric parts packed in a box from the box, and the empty box after taking out the electric parts is transported to a predetermined place using gravity. A shelf apparatus has been proposed (see, for example, Patent Document 1).

The distribution shelf device is provided so as to be swingable along the supply shelf inclined downward toward the worker, the discharge shelf inclined downward toward the discharge side, and the inclination of the supply shelf and the discharge shelf. And a switching shelf.
This distribution shelf device supplies and transports a box to be transported from the supply shelf to the switching shelf in a state where the switching shelf is in a posture along the inclination of the supply shelf, for example, assembling boxed electrical parts. The empty box after the operator has taken out the box and took out the electrical components is supplied and transported to the discharge shelf from the switching shelf that is swung along the inclination of the discharge shelf.
Japanese Utility Model Publication No. 7-23713

By the way, in the above-described conventional distribution shelf device, the size between the lower end surface of the supply shelf and the upper end surface of the discharge shelf is such that the object to be transported supplied and conveyed from the switching shelf to the lower end surface of the supply shelf. The size is set to at least the height of the object to be conveyed so as not to collide.
Here, when the height is relatively small like the conveyed object described in FIG. 1 of Patent Document 1, the dimension between the lower end surface of the supply shelf and the upper end surface of the discharge shelf can be reduced. Therefore, the inclination angle of the switching shelf can be set small according to the supply shelf and the discharge shelf.
On the other hand, when the height of the conveyed object is large, it is necessary to increase the dimension between the lower end surface of the supply shelf and the upper end surface of the discharge shelf according to the height of the conveyed object. When the dimension between the lower end surface of the supply shelf and the upper end surface of the discharge shelf is increased, the inclination angle of the switching shelf (the supply shelf side of the switching shelf is directed upward in order to receive the object to be conveyed from the upstream supply shelf) The swinging angle of the switching shelf that inevitably takes an inclined receiving posture and a transporting posture inclined so that the discharge shelf side of the switching shelf faces downward in order to transport the object to be conveyed to the downstream discharge shelf) is inevitably large. Become.
In this way, when the inclination angle of the switching shelf becomes larger than the inclination angle of the supply shelf and the discharge shelf, there is no continuity between the conveyance surface of the switching shelf and the conveyance surface of the supply shelf and the discharge shelf. There is a problem that not only can the smoothing be performed smoothly, but also the transport speed of the transported object increases at the position of the switching shelf, and there is a risk of impacting the transported object.

  In view of the problems of the above-described conventional physical distribution shelf device, the present invention is configured so that the object to be conveyed is supplied to the supply shelf even when the size between the lower end surface of the supply shelf and the upper end surface of the discharge shelf is set large. It is an object of the present invention to provide a distribution shelf device capable of setting a small inclination angle of a switching shelf that can be switched between a receiving posture for receiving and a transporting posture for transporting an object to be discharged to a discharge shelf.

In order to achieve the above object, the physical distribution shelf device of the present invention conveys the object to be conveyed conveyed from the supply shelf upstream in the conveying direction to the discharge shelf arranged downstream in the conveying direction. A receiving shelf that is inclined so that the supply shelf side of the switching shelf faces upward in order to receive the transferred object from the upstream supply shelf, and the discharged object is discharged to the downstream side. A switching shelf support mechanism is provided that can be switched to a transport posture that is inclined so that the discharge shelf side of the switch shelf faces downward for transport to the shelf, and the support mechanism of the switch shelf is switched to the transport posture. In the distribution shelf device provided with a link mechanism that supports the switching shelf at a position lower than the height position on the anti-supply shelf side of the switching shelf in the receiving posture, the height position on the anti-discharge shelf side of the shelf, The support mechanism has two positions where the switching shelf is different in the transport direction. Each of the support rods is provided with two sets of support rods that can be refracted. The support rod on the supply shelf side is connected to the operation rod via a link mechanism, and the support rod is linearly formed by the operation of the operation rod. It is possible to switch from a receiving posture that extends to support the switching shelf to a conveying posture that is refracted into a square shape, and a supporting rod on the side opposite to the supply shelf is provided in the link mechanism by operating the operating rod. The refraction operating piece is brought into contact with the refraction target piece provided on the support rod and pushed to extend the support rod in a straight line to support the switching shelf. When the operation rod is operated to switch from the receiving posture to the conveyance posture, the support rod on the anti-supply shelf side is refracted later than the support rod on the supply shelf side. It is characterized by that.

In this case, it is possible to dispose a biasing means for biasing the switching shelf in a direction that takes a receiving posture for receiving an object to be conveyed from an upstream supply shelf.

According to the distribution shelf device of the present invention, even when the dimension between the lower end surface of the supply shelf and the upper end surface of the discharge shelf is set large, the receiving posture for receiving the object to be conveyed from the supply shelf, The inclination angle of the switch shelf that can be switched to the transport posture for transporting the conveyed product to the discharge shelf can be set small, and the continuity between the transport surface of the switch shelf and the transport surface of the supply shelf and the discharge shelf is maintained. The transported object can be transported smoothly, and the transport speed of the transported object does not increase at the position of the switching shelf, and the risk of giving an impact to the transported object can be eliminated.

Then, the link mechanism of the switching shelf support mechanism, by so comprises a deflectable two pairs of supporting rods for supporting respectively the switching shelves two positions different in the conveying direction, the switching shelves simple structure The supporting mechanism can support the switching shelf at a position where the height of the switching shelf in the transporting posture on the side opposite to the discharge shelf is lower than the height of the switching shelf in the receiving posture on the side opposite to the supply shelf. .

  In addition, by making the timing of refracting the support rod supporting the switching shelf different between the two sets of support rods, the force required to refract the support rod can be dispersed and the operation can be performed smoothly. be able to.

Furthermore, when supporting the switching shelves in the receiving position, the support rod for supporting the switching shelf, by the so immediately linear between switching shelves and the transport rack body, the load applied to the switch shelf The support rod can be supported without generating a bending moment.

In addition, by providing a biasing means for biasing the switching shelf in a direction to take the receiving posture for receiving the object to be conveyed from the upstream supply shelf , the object to be conveyed is emptied to the discharge shelf. The switching shelf can be automatically returned to the receiving posture for receiving the object to be conveyed from the supply shelf.

  Embodiments of a physical distribution shelf device of the present invention will be described below with reference to the drawings.

1 to 6 show an embodiment of a physical distribution shelf device of the present invention.
This distribution shelf apparatus is a switching shelf 4 for transporting a transported object W transported from a supply shelf 2 on the upstream side in the transport direction to a discharge shelf 3 arranged on the downstream side in the transport direction. The switching shelf 4 is provided with a receiving posture 4A for receiving the transported object W from the upstream supply shelf 2 and a transporting posture 4B for transporting the transported product W to the discharge shelf 3 on the downstream side. A support mechanism 5 for the switching shelf 4 that can be switched by an operation (not particularly limited, but a stepping operation in this embodiment) is provided.

  In this case, although not particularly limited, the transport shelf main body 1 is composed of a pipe member and its coupling tool, and is also provided in the supply shelf 2 and the discharge shelf 3 and, if necessary, in the switching shelf 4. The roller member is arranged so that the article W can be smoothly conveyed.

  And this physical distribution shelf device has a locking posture 61A that protrudes from the conveyance surface of the conveyance path and engages the object W to be conveyed at the exit position of the conveyance path of the upstream supply shelf 2, and the conveyance surface of the conveyance path. The switching shelf for the article to be conveyed W can be switched to the unlocking posture 61B sunk below by an operator's operation (in this embodiment, manual operation is not particularly limited). 4, a stopper mechanism 6 that restricts the movement to 4 is disposed, and the transported object W that is locked by the stopper mechanism 6 is positioned upstream of the transported object W that is locked by the stopper mechanism 6 in the transport direction. Depending on the presence / absence of the condition, it is possible to automatically switch between a braking posture 71A that protrudes from the conveying surface of the conveying path and suppresses the moving speed of the conveyed object W, and a braking release posture 71B that sinks below the conveying surface of the conveying path. Of the transported object W The brake mechanism 7 for restricting a moving speed is to be disposed.

Further, the support mechanism 5 of the switching shelf 4 has a height position 4b on the side opposite to the discharge shelf of the switching shelf 4 in the transport posture 4B than a height position 4a on the side opposite to the supply shelf of the switching shelf 4 in the receiving posture 4A. Link mechanisms 51 and 52 are provided to support the switching shelf 4 at a low position.
In this way, the height position 4b of the switching shelf 4 in the transport posture 4B on the side opposite to the discharge shelf (the edge of the switching shelf 4 opposite to the discharge shelf 3) is the anti-supply of the switching shelf 4 in the receiving posture 4A. By supporting the switching shelf 4 at a position lower than the height position 4a on the shelf side (the edge of the switching shelf 4 opposite to the supply shelf 2), the lower end surface of the supply shelf 2 and the top of the discharge shelf 3 are supported. Even when the dimension between the end faces is set to be large, it is possible to switch between a receiving posture 4A for receiving the conveyed object W from the supply shelf 2 and a conveying posture 4B for conveying the conveyed object W to the discharge shelf 3. The inclination angle of the switching shelf 4 can be set small, and the conveyance surface of the switching shelf 4 and the conveyance surface of the supply shelf 2 and the discharge shelf 3 are maintained, so that the object W is smoothly conveyed. In addition, the transport speed of the transported object W does not increase at the switching shelf 4 and the transported object W Shock so that it is possible to eliminate the fear.

  The link mechanisms 51 and 52 are provided with two sets of refracting support rods 51a and 52a that respectively support the switching shelf 4 at two different positions in the transport direction, thereby enabling simple structure switching. By the support mechanism 5 of the shelf 4, the height position 4b on the side opposite to the discharge shelf of the switching shelf 4 in the transport posture 4B is lower than the height position 4a on the side opposite to the supply shelf of the switching shelf 4 in the receiving posture 4A. The switching shelf 4 can be supported.

Here, when the switching shelf 4 in the receiving posture 4A is supported, the two sets of support rods 51a and 52a that support the switching shelf 4 are arranged between the switching shelf 4 and the transport shelf body 1 in a substantially vertical direction (here The term “substantially vertical” means an angle of about 70 ° or more with respect to the horizontal, but it is desirable that the angle be about 80 ° or more.) desirable. Thereby, the load applied to the switching shelf 4 can be stably supported without generating a bending moment in the support rods 51a and 52a.
The support rods 51a and 52a are pivotally supported at the lower ends thereof on the rails 11 and 12 of the transport shelf main body 1, and the intermediate portions are formed so as to be able to be bent in a substantially square shape. To support.
The support rods 51a and 52a include springs 51b and 52b that urge the support rods 51a and 52a in a linear direction.

On the upper side of the support rod 51a on the supply shelf 2 (discharge shelf 3) side, a stepping operation rod 53 pivotally supported on the conveyance shelf main body 1 is connected via a link mechanism 54, and the stepping operation rod 53 is provided. When the stepping operation is performed, the support rod 51a extends linearly in a substantially vertical direction to support the switching shelf 4 (at this time, the switching shelf 4 accepts the object W to be received from the upstream supply shelf 2). (At this time, the switching shelf 4 takes a transport posture 4B for transporting the article W to be transported to the discharge shelf 3 on the downstream side). To do.
The support rod 52a on the side opposite to the supply shelf 2 (anti-discharge shelf 3) is configured such that when the stepping operation rod 53 is stepped on, the refraction operation piece 54a provided on the link mechanism 54 is operated for refraction of the support rod 52a. A state where the support rod 52a is linearly extended in a substantially vertical direction to support the switching shelf 4 by contacting and pushing the piece 52c (at this time, the switching shelf 4 supplies the transported object W to the upstream side. From the accepting posture 4A received from the shelf 2, the switching shelf 4 takes a conveying posture 4B for conveying the article W to be conveyed to the downstream discharging shelf 3 (reflected in a substantially letter-like shape). ).
In this case, the timing of refracting the support rods 51a and 52a that support the switching shelf 4 is made different between the two sets of support rods. Specifically, the support rod 51a on the supply shelf 2 (discharge shelf 3) side is set to the anti-supply shelf. 2. By refracting faster than the support rod 52a on the 2 (anti-discharge shelf 3) side, the force required to refract the support rods 51a, 52a can be dispersed, and a series of operations can be performed smoothly. Can do.
The support rods 51a and 52a are provided with springs 51b and 52b that urge the support rods 51a and 52a in a straight line direction. The operation rod 53 and the support rods 51a and 52a return to the initial state.
In this case, the support rod 52a on the side of the anti-supply shelf 2 (anti-discharge shelf 3) is configured such that the return operation piece 54b provided in the link mechanism 54 is supported by the support rod 52a by releasing the stepping operation of the stepping operation rod 53. The support rod 52a is surely returned to the initial state by abutting and pushing the return operation piece 52d.

  Note that the support mechanism 5 of the switching shelf 4 includes a receiving posture 4A for receiving the transported object W from the upstream supply shelf 2 and a transporting posture for transporting the transported object W to the discharge shelf 3 on the downstream side. The height position 4b on the side opposite to the discharge shelf of the switching shelf 4 in the transport posture 4B is lower than the height position 4a on the side opposite to the supply shelf of the switching shelf 4 in the receiving posture 4A. The mechanism is not limited to the above as long as it can support the switching shelf 4.

On the other hand, the switching shelf 4 is energized in a direction that takes the receiving posture 4A for receiving the conveyed product W from the upstream supply shelf 2, and the conveyed product W is transported and placed on the switching shelf 4 in the receiving posture 4A. At the same time, the urging means 8 that sets the urging force so as to switch to the conveying posture 4B for conveying the article W to be conveyed to the downstream discharge shelf 3 when the support mechanism 5 of the switching shelf 4 is released Arrange.
Specifically, a weight 81 attached via a rope 82 can be suitably used as the urging means 8.
Accordingly, the switching operation of the switching shelf 4 can be performed with a small force, and the switching shelf 4 in the transporting posture 4B that has been emptied by transporting the transported object W to the discharge shelf 3 can be replaced with the transported object W. It is possible to automatically return to the receiving posture 4A received from the supply shelf 2.

The stopper mechanism 6 that regulates the movement of the transported object W to the switching shelf 4 is a mechanism that protrudes from the transport surface of the transport path at the exit position of the transport path of the upstream supply shelf 2 to lock the transported object W. A stopper piece 61 that restricts the movement of the article W to be transferred to the switching shelf 4 by enabling switching between a stopping posture 61A and a locking release posture 61B submerged below the conveying surface of the conveying path, and a stopper piece 61 The operation mechanism 62, the operation mechanism 62 for the operator to operate the operation mechanism 62 (in this embodiment, although it is not particularly limited, and the manual operation for manual operation), and the operation mechanism 63 are operated by the operator. The stopper piece 61 includes a spring 64 that urges the operation mechanism 62 so that the stopper piece 61 assumes a locking posture 61A when not being operated.
Here, the operating mechanism 62 of the stopper piece 61 is pushed and operated by the operating rod 63 and swings. The operating piece 62 is urged by the spring 64 and is interlocked with the operated piece 62a. And the operation piece 62b for operating the stopper piece 61.

The brake mechanism 7 that regulates the moving speed of the transported object W includes the presence or absence of the transported object W locked by the stopper mechanism 6 at a position upstream of the transported object W locked by the stopper mechanism 6 in the transport direction. Accordingly, it is possible to automatically switch between a braking posture 71A that protrudes from the conveyance surface of the conveyance path and suppresses the moving speed of the conveyed object W and a braking release posture 71B that sinks below the conveyance surface of the conveyance path. Thus, the brake piece 71 is in the brake release posture 71B in a state where there is no brake piece 71 that regulates the moving speed of the transferred object W, the operation mechanism 72 of the brake piece 71, and the transferred object W locked by the stopper mechanism 6. And a spring 73 that urges the operation mechanism 72 to take
Here, the operation mechanism 72 of the brake piece 71 is pushed and swung by the conveyed object W locked by the stopper mechanism 6 and is substantially L-shaped operated piece 72 a urged by the spring 73. And an operation piece 72c for operating the brake piece 71 in conjunction with the operated piece 72a via the link rod 72b.

Next, the operation of the physical distribution shelf device will be described.
First, when the articles to be conveyed W are sequentially supplied from the starting end of the supply shelf 2 on the upstream side in the conveyance direction, the article to be conveyed W has a locking posture 61A of the stopper mechanism 6 disposed at the exit position of the conveyance path of the supply shelf 2. The stopper piece 61 is locked.
At this time, the transported object W subsequent to the transported object W locked by the stopper mechanism 6 is such that the transported object W locked by the stopper mechanism 6 exists on the operated piece 72 a of the brake mechanism 7. Thus, it is possible to prevent the subsequent transported object W from strongly colliding with the transported object W that is braked by the brake piece 71 of the stopper mechanism 6 that is automatically switched to the braking posture 71A and is locked by the stopper mechanism 6.

Next, when the operator manually pushes the operating rod 63 of the stopper mechanism 6 to switch the stopper piece 61 from the locking posture 61A to the locking release posture 61B, the conveyed object W is supplied to the upstream side. It is automatically transported and placed on the switching shelf 4 taking the receiving posture 4A received from the shelf 2.
At this time, the transported object W subsequent to the transported object W locked by the stopper mechanism 6 is the time when the transported object W locked by the stopper mechanism 6 exists on the operated piece 72 a of the brake mechanism 7. Is braked by the brake piece 71 of the stopper mechanism 6 that is automatically switched to the braking posture 71A, but when the article W to be conveyed is conveyed to the switching shelf 4, the brake piece 71 of the stopper mechanism 6 is released from the braking release posture 71B. The transported object W starts to move. The transported object W is a stopper mechanism that automatically returns to the locking posture 61A by releasing the pushing operation of the operating rod 63 after the previous transported object W is transported and placed on the switching shelf 4. 6 stopper pieces 61. In this way, when receiving the transported object W from the supply shelf 2 to the switching shelf 4, the start of the subsequent transported object W can be delayed, and the subsequent transported object W is reliably engaged by the stopper mechanism 6. Can be stopped.

For the transported object W supplied and transported to the switching shelf 4, for example, an operator sequentially takes out electrical components or the like packed in the transported object W and performs assembly work.
And after taking out the electrical components etc. which were packed in the to-be-conveyed object W, by stepping on the stepping operation rod 53 of the support mechanism 5 of the switching shelf 4, the support rod 51a is extended linearly in the substantially vertical direction. The state in which the switching shelf 4 is supported (at this time, the switching shelf 4 takes the receiving posture 4A for receiving the conveyed object W from the upstream supply shelf 2) and is refracted into a substantially square shape (at this time). The switching shelf 4 is in a transport posture 4B for transporting the transported object W to the discharge shelf 3 on the downstream side.
Further, the support rod 52a on the anti-supply shelf 2 (anti-discharge shelf 3) side is delayed from the support rod 51a on the supply shelf 2 (discharge shelf 3) side by the stepping operation of the stepping operation rod 53, and the link mechanism The refraction operation piece 54a provided on 54 is brought into contact with and pushed by the refraction target piece 52c of the support rod 52a, and the support rod 52a extends linearly in a substantially vertical direction to support the switching shelf 4. From the state (at this time, the switching shelf 4 takes the receiving posture 4A for receiving the conveyed object W from the upstream supply shelf 2), it is refracted into a substantially square shape (at this time, the switching shelf 4 is The transport posture 4B for transporting the transported object W to the discharge shelf 3 on the downstream side is taken.
In this way, the object to be transported (empty box) W is transported to the discharge shelf 3 on the downstream side.
The switching shelf 4 in the transporting posture 4B that has been emptied after transporting the transported object W to the discharge shelf 3 is automatically set to the receiving posture 4A for receiving the transported material W from the supply shelf 2 by the action of the urging means 8. However, since the support rods 51a and 52a are also provided with springs 51b and 52b that urge the support rods 51a and 52a in a linear direction, when the stepping operation of the stepping operation rod 53 is canceled, Therefore, the stepping operation rod 53 and the support rods 51a and 52a return to the initial state.
In this case, the support rod 52a on the side of the anti-supply shelf 2 (anti-discharge shelf 3) is configured such that the return operation piece 54b provided in the link mechanism 54 is supported by the support rod 52a by releasing the stepping operation of the stepping operation rod 53. The support rod 52a reliably returns to the initial state by abutting and pushing the return operation target piece 52d.

  Hereinafter, similarly, a receiving posture 4A for receiving the object W to be conveyed from the supply shelf 2 on the upstream side in the conveyance direction from the supply shelf 2 on the upstream side, and the downstream side of the object W to be conveyed W After transporting and placing on the switching shelf 4 which can be switched to the transporting posture 4B for transporting to the discharge shelf 3 and performing necessary work, the discharged object W is disposed downstream from the switching shelf 4 in the transporting direction. The conveyance to the shelf 3 is repeated.

Thus, in this distribution shelf device, the height position 4b on the side opposite to the discharge shelf of the switching shelf 4 in the transport posture 4B is higher than the height position 4a on the side opposite to the supply shelf of the switching shelf 4 in the receiving posture 4A. Even when the dimension between the lower end surface of the supply shelf 2 and the upper end surface of the discharge shelf 3 is set large by supporting the switching shelf 4 at the low position, the transported object W is supplied to the supply shelf. 2, the inclination angle of the switching shelf 4 that can be switched between the receiving posture 4 </ b> A and the conveying posture 4 </ b> B that transports the object W to the discharge shelf 3 can be set small. 2 and the discharge shelf 3 can be maintained continuously with the transfer surface, and the transfer of the transfer object W can be performed smoothly, and the transfer speed of the transfer object W can be increased at the switching shelf 4. There is no risk of giving an impact to the conveyed object W.
In addition, the distribution shelf device includes a switching shelf 4 that can be switched between a receiving posture 4A for receiving the transported object W from the supply shelf 2 and a transporting posture 4B for transporting the transported product W to the discharge shelf 3. In addition, it is possible to adopt a configuration that can easily be moved when the layout is changed without requiring special electric supply equipment or cylinder equipment piping equipment.

  The physical distribution shelf device of the present invention has been described based on the embodiments thereof, but the present invention is not limited to the configurations described in the above embodiments, and the configurations are appropriately set within the scope not departing from the gist thereof. It can be changed.

  The distribution shelf device of the present invention has a receiving posture for receiving an object to be conveyed from the supply shelf, even if the dimension between the lower end surface of the supply shelf and the upper end surface of the discharge shelf is set large, and the object to be conveyed Since the inclination angle of the switching shelf that can be switched to the transporting posture for transporting the product to the discharge shelf can be set small, for example, an operator takes out the electrical components packed in a box at an electrical equipment assembly factory and performs predetermined assembly work. For example, it can be suitably used for the application of a distribution shelf device used for the purpose of
