Description

  The present invention relates to a roller conveyor and a mounting structure for the roller conveyor and the like.

  A roller conveyor used in a distribution center or the like that is dispersedly driven by a small motor or the like has a driving range composed of a plurality of zones (for example, Patent Documents 1 and 2).

As shown in FIG. 12, for example, such a roller conveyor has a plurality of carrier rollers 2 for transporting a conveyed product in each zone , and a driving device for driving the carrier rollers 2 (the driving device is, for example, a carrier roller). 2), a control device 3 for controlling the operation of the driving device, sensors (stock sensors) 4a, 4b for detecting the conveyed product, etc., and the conveyor frame 5 is a carrier roller. The conveyance path is formed so as to sandwich 2 from both sides.

  The control device 3 transmits information between the control device 3 in the other zone and the host controller, and controls the rotational driving of the carrier roller 2 in its own zone. For example, when paying attention to one zone, when the in-zone sensors 4a and 4b in the zone detect a conveyed product conveyed from the upstream zone, the control device 3 in the zone will detect the in-zone sensor 4a in the downstream zone. 4b, whether or not to transport the detected transported object to the downstream zone is determined according to the staying status of the other transported object detected, and the rotation of the carrier roller 2 is controlled to increase the transport speed, Slow down or stop. In this way, the amount of accumulation (retention) of the conveyed product in a certain length of the conveyor is controlled (Patent Documents 1 and 2).

  By the way, in the accumulating amount control performed for each zone, the control conditions for transporting the conveyed product from the upstream to the downstream are different for each zone. Therefore, the control device 3 is provided with an adjustment switch for setting control conditions for each zone.

  Since such a control device 3 generally operates an adjustment switch from the outside of the frame, it is attached to the outside of the conveyor frame for each zone. In such a roller conveyor, wiring for electrical connection with upstream and downstream control devices, drive devices, or a host controller is exposed to the outside of the frame, and it is inevitable that workability is lowered in control condition setting work. Therefore, a technique has been proposed in which a control device is attached to the inside of the conveyor frame and an operation hole 3a for operating the adjustment switch from the outside of the conveyor frame 5 is formed in the conveyor frame 5 (Patent Document 2).

JP 2011-140362 A JP 2005-187168 A

  By the way, the installation conditions in the transfer line are often different depending on the circumstances, and the installation position of the control device on the conveyor frame may be restricted (for example, even if an operation hole is provided for contact with other conveyors) Etc.).

  In addition, an accumulation conveyor is often used to efficiently supply a large number of transported goods upstream of the sorting equipment, but if the control device is installed outside the conveyor frame, the adjustment switch of the control device is difficult to operate. This is time consuming and increases the initial setup costs when installing the conveyor. Also, the operation of the adjustment switch can be extremely difficult. Of course, the work cost during the maintenance inspection also increases.

  As a result, not only the mounting position of the control device but also the route of the electrical wiring between the drive device and the control device will be different, and the assembly work and wiring work will become complicated. Construction costs will increase.

Therefore, in order to solve the above problems, the present invention can easily operate the adjustment switch of the control device regardless of the installation conditions of the conveyor, and the electrical wiring path between the drive device and the control device. The length of the cable is not affected by the installation, and the cable installation is easy. Therefore, the manufacturing cost of the conveyor, the cost of the control setting work, etc. can be reduced, and the adjustment switch etc. of the control device is operated. An object of the present invention is to realize a mounting structure such as a roller conveyor and a control device for the roller conveyor, which can reduce the labor and cost of manufacturing by eliminating the need for a large hole for operation.

In order to solve the above problems, the present invention provides a plurality of carrier rollers arranged to form a conveyance path, a conveyor frame that rotatably supports these carrier rollers, and a conveyance path divided into a plurality of zones. In a roller conveyor, comprising: a driving device disposed in each zone that rotationally drives a carrier roller in each zone; and a control device that controls the driving device to control the conveyance speed of a conveyed product for each of a plurality of zones. In order to enable adjustment of the adjustment means provided from the upper side of the carrier roller, the drive device and the control device are positioned below the conveying surface of the carrier roller, and the adjustment means provided in the control device is provided from the gap between the carrier rollers. It was set as the structure to adjust (Claims 1 and 5).
Here, the carrier roller may include a driving device (claims 9 and 11). Further, a control device positioned below the carrier roller conveyance surface may be pulled out above the carrier roller conveyance surface by a drawing mechanism. In this case, it is only necessary that at least a part of the control device can be drawn upward from the conveyance surface (claims 13, 15, 17, and 19).
The transport surface of the carrier roller is a virtual surface in contact with the uppermost portion of each carrier roller, and can also be referred to as a traveling surface of the transported object.

  In the case of the roller conveyor having such a structure and its control device mounting structure, the adjustment means of the control device can be visually observed from the gap between the carrier rollers. Even so, the adjustment operator can easily operate the adjustment means (adjustment switch) of the control device from above the carrier roller. Further, since the electrical wiring between the driving device and the control device is determined by the positional relationship between the driving device and the control device in the conveyor frame, the wiring work of the roller conveyor is simplified. Of course, there is no need to drill holes for operation in the conveyor frame.

  In this case, as described in claims 2, 6, 14 and 16, an attachment portion for attaching the drive device and the control device is provided, and the attachment portion is attached to the conveyor frame. It is possible to simplify the mounting of the device and the electric wiring work between the two devices. Even if the carrier roller has a built-in driving device, the mounting of the device on the conveyor frame and the electric wiring work between the devices can be simplified (claims 10, 12, 18 and 20).

  If the roller conveyor having such a structure and its control device mounting structure are used, electrical wiring may be applied after mounting the two devices on the mounting portion before mounting them on the conveyor frame, or After attaching the attachment part to the conveyor frame, electrical wiring may be performed by attaching the two devices to the attachment part. Of course, since the positional relationship between the two devices is determined by the mounting position on the mounting portion, the mounting work is easy, and the electrical wiring work can be easily performed by connecting a wire harness produced in advance.

  The conveyor frame includes not only components directly constituting the conveyor frame but also components integrated directly or indirectly with the conveyor frame, and can be said to be substantially a conveyor frame.

  According to a third and seventh aspect of the present invention, the attachment portion includes two attachment portions, that is, a first attachment portion for attaching the driving device and a second attachment portion for attaching the control device. The attachment portions may be connected and integrated. In this case, the attachment portion can be attached to the conveyor frame by one or both of the first and second attachment portions.

  Alternatively, as described in claims 4 and 8, the first and second attachment portions may be separately attached to the conveyor frame without being integrated.

  As described above, the roller conveyor according to the present invention and its mounting structure such as a control device can easily operate the adjustment switch of the control device even when a plurality of conveyors are arranged close to each other. Since the electrical wiring between the drive unit and the control unit is not affected by surrounding conditions such as the arrangement of the conveyor, the manufacturing cost of the roller conveyor, the cost of installation work, etc. can be reduced, and the control unit has Since an operation hole for operating an adjustment switch or the like is not necessary, the manufacturing cost can be reduced.

FIG. It is a figure which shows an example of a schematic perspective structure of the conventional roller conveyor.

  Hereinafter, with reference to the drawings, a roller conveyor according to the present invention and a mounting structure such as a control device thereof will be described.

<Example 1>
First, a description will be given of a roller conveyor according to the present invention and a first embodiment of the mounting structure such as a control device thereof.

<General configuration of roller conveyors>
As shown in FIGS. 1 to 3, the roller conveyor 10 is configured to have a plurality of zones Z (i) (i = 1, 2,... J), and each zone Z (i) , N carrier rollers 11 (k) (k = 1, 2,..., N) arranged so as to form a transport path F, and a conveyor for rotatably supporting these carrier rollers 11 (k). A frame 12, a driving device 20, and a control device 30 are provided.

  The substantially cylindrical carrier roller 11 (k) has one end rotatably supported by one side 12a of the conveyor frame 12 and the other end rotatably supported by the other side 12b of the conveyor frame 12 ( For example, see FIG. 2), two adjacent carrier rollers 11 (k) are all arranged in parallel with a gap G (the gap G is, for example, approximately the same as the diameter of the carrier roller 11 (k)). Set to.)

  From the carrier roller 11 (1) to the carrier roller 11 (m-1), a belt 11a is hung between two adjacent carrier rollers 11 (k) (for example, the carrier roller 11 (1) and the carrier roller). 11 (2), the first belt 11a, the second roller 11a between the carrier roller 11 (2) and the carrier roller 11 (3), and the belt 11a in the same manner. ). The belt 11a is similarly hung on the carrier rollers 11 (m) to 11 (n).

  As shown in FIGS. 2 and 3, the carrier roller 11 (m-1) is rotationally driven by the driving device 20 through the driving belt 21a, and the carrier roller 11 (m) is driven through the driving belt 21b. 20 is rotationally driven. Therefore, all the carrier rollers 11 (k) constituting the transport path F of the zone Z (i) can be rotated in the same direction and in the same direction by the driving device 20 to transport the transported object in the direction of the arrow.

  In the driving device 20, a driving main body 20a incorporating a motor, a motor driving circuit, and the like is fixed to the mounting portion 40 (for example, by screws), and a pulley portion 20b that is rotatably provided at one end of the driving main body 20a. The carrier rollers 11 (m−1) and 11 (m) are driven to rotate by the drive belts 21 a and 21 b that are applied to the belt.

  As shown in FIG. 2, the drive device 20 and the control device 30 having a substantially rectangular parallelepiped shape are attached to the conveyor frame 12 via the attachment portion 40. Specifically, after attaching the driving device 20 and the control device 30 to the attachment portion 40, one end 40a (see FIG. 3) of the attachment portion 40 is one of the conveyor frames 12 positioned below the carrier roller 11 (k). While being attached to the side portion 12a, the other end portion 40b of the attachment portion 40 is similarly attached to the other side portion 12b of the conveyor frame 12. Alternatively, the drive device 20 and the control device 30 may be attached to the attachment portion 40 after attaching the attachment portion 40 to the conveyor frame 12.

  Here, the control cable 31 that electrically connects the drive device 20 and the control device 30 has connectors at both ends, for example, and can connect both devices. The connection of the control cable 31 can be performed either before or after the attachment portion 40 is attached to the conveyor frame 12.

  Thus, the control device 30 attached to the zone Z (i) controls the driving device 20 to control the rotation speed of the carrier roller 11 (k), thereby conveying the conveyed product to the downstream zone Z (i + 1). (Control of conveyance speed, conveyance stop, etc.)

  In addition, 13a and 13b in FIG. 1 are sensors (stock sensor) for detecting the conveyed product in the zone Z (i).

<About the control device and its adjusting means>
As shown in FIGS. 2 and 3, the control device 30 having a substantially rectangular parallelepiped shape has an adjustment surface 30 a whose upper surface is substantially rectangular, and a plurality of control devices 30 are provided in the longitudinal center line of the adjustment surface 30 a and / or in the vicinity thereof. The adjustment switch 30b is provided.

  The width of the control device 30 (the length of the short side of the adjustment surface 30a) is, for example, approximately the same as the gap G between the two adjacent carrier rollers 11 (k). The control device 30 is positioned so that the vicinity of the center line in the long side direction of the adjustment surface 30a can be confirmed from the gap G between the carrier rollers 11 (m-1) and 11 (m) and is parallel to the rotation axes of both the carrier rollers. It has been. Here, the control device 30 and the carrier roller 11 (k) do not necessarily have to be parallel to each other as long as the adjustment switch 30b can be confirmed from the gap G between the carrier rollers 11 (m-1) and 11 (m). The adjustment surface 30a may be inclined or inclined with respect to the carrier roller 11 (k).

  Further, as shown in FIGS. 4A and 4B, when the width of the control device 30 is narrower than the gap G between the two adjacent carrier rollers 11 (m-1) and 11 (m), they are adjacent to each other. The control device 30 is positioned between the two carrier rollers 11 (m-1) and 11 (m), and the adjustment surface 30a of the control device 30 is positioned below the conveying surface 11s of the carrier roller 11 (k). Can also be positioned.

  By arranging the drive device 20 in the width direction of the conveyor frame 12 and the longitudinal center line of the adjustment surface 30a of the control device 30 so as to substantially coincide with each other, the adjustment switch 30b of the drive device 20 is disposed on the other side of the conveyor frame 12. The drive belts 21a and 21b can be positioned on the one side 12a side (or the other side portion 12b side) of the conveyor frame 12 while being positioned on the portion 12b side (or the one side portion 12a side).

  In the roller conveyor having such a configuration and the mounting structure of the control device and the like, the plurality of adjustment switches 30b of the control device 30 can be adjusted from the gap G between the carrier rollers 11 (m-1) and 11 (m) (see FIG. 3, FIG. 4).

  When the conveyance path F is a curve in plan view, the arrangement of the rotation shafts of the carrier rollers 11 (k) is not parallel. Even in such a case, the control device 30 may be positioned so that the adjustment switch 30b can be confirmed from the gap G between the two adjacent carrier rollers 11 (k).

  By the way, the control device 30 is connected not only to a connector for connecting a control cable 31 wired between the drive device 20 but also to a control device (not shown) in another zone and a host controller (not shown). A connector for connecting a control cable is provided. Therefore, in the roller conveyor 10 having such a configuration (including the attachment structure of the control device and the like), not only the control cable 31 but also other control cables can be easily attached even after the attachment portion 40 is attached to the conveyor frame 12. It can be wired.

<First Modification>

  Here, the first and second attachment portions 40 ′ and 41 may be connected before or after the first attachment portion 40 ′ is attached to the conveyor frame 12. The drive device 20 and the control device 30 may be attached to the first and second attachment portions 40 ′ and 41 either before or after the attachment of both attachment portions 40 ′ and 41.

  In the first modification, the driving rollers 21a and 21b are hung on the carrier rollers 11 (m) and 11 (m-1), and the gap G between the carrier rollers 11 (m-1) and 11 (m-2) is used. The adjustment switch 30b of the control device 30 can be made visible. Therefore, for example, when the drive device 20 and the carrier roller 11 (k) have the same length, and the drive device 20 and the control device 30 must be arranged substantially in parallel, the configuration of the first modification example is as follows. Also good.

In addition, the same code | symbol is attached | subjected to the component which has the same function as the roller conveyor 10, and those description is abbreviate | omitted.

  In the second modified example, the attachment portion 40y includes a first attachment portion 40 'for attaching the drive devices 20 separated from each other, and a second attachment portion 42 for attaching the control device 30. The second mounting portion 42 is parallel to the first mounting portion 40 'positioned below the carrier rollers 11 (m) and 11 (m-1), for example, and the carrier roller 11 (k ) On one side 12a of the conveyor frame 12 located below.

  At this time, the second mounting portion 42 is positioned below, for example, the carrier rollers 11 (m-2) and 11 (m-3), so that the adjustment switch 30b of the control device 30 is moved to the carrier roller 11 (m-2). And 11 (m−3) gap G. Therefore, for example, when the drive device 20 and the carrier roller 11 (k) are approximately the same length, and the drive device 20 and the control device 30 must be arranged substantially in parallel, the configuration of the second modification example is as follows. Also good.

  Further, by selecting whether the second attachment portion 42 is attached to one side portion 12a of the conveyor frame 12 or to the other side portion 12b, the adjustment switch 30b of the control device 30 is set to one side portion of the conveyor frame 12. It can be located on any side of 12a or other side 12b. As described above, in the second modification, the position of the second mounting portion 42 can be selected, so that the position of the adjustment switch 30b of the control device 30 is set according to the ambient conditions of the zone Z (i). Can do.

<Example 2>
Next, another embodiment (embodiment 2) of the roller conveyor according to the present invention and its mounting structure such as its control device will be described. The second embodiment is different from the first embodiment in that the driving device is built in the carrier roller, and the configuration of the control device, the carrier roller, and the mounting portion 40 which are different from the first embodiment will be described (implementation). The description of components common to Example 1 is omitted.)

  The carrier roller 11 (m−1) shown in FIG. 9 includes a drive device 20 ′. The carrier roller 11 (m) is rotationally driven by the carrier roller 11 (m-1) that is rotationally driven by the driving device 20 'via the driving belt 21a. The control device 30 is attached to the conveyor frame 12 via the attachment portion 40 in the same manner as the control device 30 in the first embodiment. Of course, similarly to the modification of the first embodiment, the control device 30 can be attached to the conveyor frame 12 via the attachment portion 40x or 40y (see FIGS. 5 to 8).

  FIG. 10 is a diagram schematically comparing the differences between the roller conveyor and the like in the first embodiment (FIG. 10A) and the roller conveyor and the like in the second embodiment (FIG. 10B). Thus, in the second embodiment, all the carrier rollers 11 (k) constituting the conveyance path F of the zone Z (i) are rotationally driven by the driving device 20 'to convey the conveyed product.
