[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roller conveyor, and more particularly to a chain guide for a conveyor for rotating a roller.

[0002]

[Prior art]

 Conventionally, there are various types of roller conveyors. For example, a plurality of rollers are provided in a main body composed of parallel side frames so as to freely rotate to form a conveying path. Then, a sprocket provided directly on this roller or a sprocket provided on another contact wheel is engaged with the drive chain. According to this conventional type, the drive chain causes the rollers to rotate through the sprockets, whereby the rotation of the roller group moves the object to be conveyed on the conveying path. In the roller conveyor as described above, a chain guide for guiding the traveling of the driving chain is formed separately from the above-mentioned conveyor side frame, and is disclosed in, for example, Japanese Utility Model Publication No. 4-1128. .

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional chain guide is a member that is long along the conveyor side frame, and is attached to the conveyor side frame by sliding it in the longitudinal direction. Therefore, with the structure disclosed in the above publication, it is necessary to pull out and insert the entire chain guide at the time of maintenance such as replacement of the guide rail that is incorporated in the chain guide and comes into contact with the chain. This pulling out and inserting operation is quite difficult because the chain guide is long, and if the insertion and fitting are not successful, the fitting part of the side frame or the chain guide will be damaged. There was a high risk of causing it. Further, in this chain guide, since the chain rail portion is incorporated in the guide frame, the number of parts is large.

Further, since the chain guide as described above is fitted and mounted, if the fitted portion is damaged, the chain guide cannot be mounted, and the conveyor side frame that can be mounted is determined. It could not be used for the conveyor side frame. The present invention has been made to solve the above problems, and an object of the present invention is to provide a chain guide in which the conveyor side frame can be freely attached and detached, and its constituent members can be attached to any conveyor side frame.

[0005]

[Means for solving problems]

 The above object of the present invention is to provide a chain guide for a conveyor, wherein a chain for driving a conveying roller is provided along a side frame of the conveyor, and constitutes a moving path of the chain, wherein the chain guide is a forward path and a backward path of the chain. And a pair of chain rails that are also formed, a mounting wall, and a position regulating wall that extends higher than the chain rail on the opposite side of the mounting wall, and the mounting wall is fitted to the conveyor side frame. It is achieved by a chain guide for a conveyor, characterized in that the moving path is constituted by a plurality of units each having a fitting portion and a screw hole for screwing and shorter than the length of the conveyor side frame. can do.

[0006]

[Action]

 The chain guide configured as described above is formed of an integrally molded product that has a pair of chain rails that also form a forward path and a return path of the chain, a mounting wall, and a position regulating wall that extends higher than the chain rail on the opposite side of the mounting wall. As a result, the number of components is smaller than when the chain rail was constructed separately as in the past, and the ease of mounting on the conveyor side frame can be improved. In addition, the mounting wall has a fitting part that fits on the conveyor side frame and a stop hole for screw fixing, so that only the fitting part is attached, only the screw is attached, or both the fitting part and the screw are used together. It is possible to support multiple types of mounting such as the above mounting. Further, the invented chain guide is composed of a plurality of units shorter than the length of the conveyor side frame, and the chain traveling path can be easily changed by removing some of the units.

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail. FIG. 1 is a perspective view showing a form using a stop screw in a chain guide according to an embodiment of the present invention, and FIG. 2 is a side view showing an attaching form using a fitting portion of the chain guide shown in FIG. Yes, FIG. 3 is a front view thereof. In the chain guide 1 shown in FIG. 1, a chain 25 for driving a conveying roller (not shown) rotatably attached to the upper side of the conveyor side frame 20 is run along the conveyor side frame 20. It is a member that constitutes a moving path to be guided.

The chain guide 1 has a mounting wall 2 that is a mounting portion to the conveyor side frame 20, and bottom portions 23 and 24 that horizontally project from a middle portion and a lower end portion of the mounting wall 2 to form a moving path. Chain rails 9 are formed respectively on the forward and backward paths A (upper side in the figure) and backward path B (lower side in the figure) of the chain 25. Position control walls 3 and 4 extending higher than the chain rail 9 are provided on the side opposite to the mounting wall 2 with the bottom portions 23 and 24 interposed therebetween, and further, the mounting wall 2 projects toward the conveyor side frame 20 side. A mounting protrusion 6 is formed. For example, four fixing holes 8 are formed in the mounting wall 2 at positions corresponding to the fitting portion 5 and the mounting projection 6.

The fitting portions 5 and 7 are configured such that the protruding tip portions thereof are bent downward, and have a function as a fitting portion described later. The chain guide 1 having the above-mentioned structure is integrally formed of a material such as aluminum, and is fixed to the conveyor side frame 2 by the stop screw 10 that fits through the stop hole 8. A plurality of units (see FIG. 3) shorter than the length of the side frame 2 can be attached so as to be arranged at appropriate intervals.

Further, the chain conveyor 1 shown in FIG. 1 can adopt a mounting form as shown in FIG. In the mounting method shown here, the hook portion 21 is provided on the conveyor side frame 20, and the fitting portions 5 and 7 are fitted to the hook portion 21. Incidentally, in order to prevent the mounting position of the chain conveyor 1 from being displaced, some locking tool may be provided separately, but in the present embodiment, two stop screws 10 (one may be provided. ) It can be fixed by mounting.

The chain guide 1 configured as described above has the chain rail 9, the mounting wall 2, and the position regulating walls 3 and 4 extending higher than the chain rail 9 on the side opposite to the mounting wall 2. Since it is an integrally molded product, the number of components can be reduced compared to the conventional chain rail that was configured separately. As a result, the chain conveyor 1 can be easily attached to the conveyor side frame 20. Further, since the mounting wall 2 is provided with both the fitting portions 5 and 7 for fitting to the conveyor side frame 20 and the fixing hole 8 for screw fixing, only the fitting portion 7 is attached or only the screw 10 is provided. It is possible to adopt a plurality of mounting forms such as the mounting form described in (1) or further using the fitting parts 5 and 7 and the screw 10 together, and the versatility is high. Further, the chain guide 1 is composed of a plurality of units shorter than the length of the conveyor side frame 20, so that the chain traveling route can be easily changed by the arrangement in which some of the units are removed or the arrangement is intermittent. You can For example, the chain traveling path can be changed to a desired position for hanging the chain 25 on a driving device such as a motor.

In order to prevent the chain 25 from coming off the chain rail 9 during traveling, the position regulating walls 3 and 4 are formed higher than the chain rail 9. Furthermore, since the position regulating wall 4 and the upper bottom portion 23 have a space W, and the size of the space W is configured to pass through the chain 25, the space W can be installed or removed. Can move the chain 25 in and out of the path at any time. Further, the chain guide 1 has hooks 2a, 3a formed at the upper ends of the mounting wall 2 and the position restricting wall 3, and is attached to, for example, the housing of the drive unit 30 of the conveying roller in correspondence with the hooks 2a, 3a. By providing the portion, the chain guide 1 can be used as an attachment aid for the drive unit 30, and on the other hand, the chain guide 1 can be provided with the function of preventing lateral displacement by the drive unit 30.

The present invention is not limited to the above embodiment, but can be modified in various ways, for example, the structure shown in FIGS. 4 to 8 can be adopted. In the structure shown in FIGS. 4 and 5, the conveyor side frame 20 is provided with fitting holes 22 having an appropriate shape, and for example, four fitting portions 5 of the chain guide 1 are fitted into the fitting holes 22. This is the configuration. If the fitting hole 22 is, for example, a small-diameter portion for fixation that is continuous with a large-diameter portion into which the tip portion of the fitting portion 5 can be inserted, the fitting portion 5 is inserted and the chain is moved appropriately. The guide 1 can be attached.

The chain guide 1 shown in FIG. 6 has the same structure as that shown in FIG. Then, the conveyor side frame 20 is formed with a hook portion 26 corresponding to the shape of the fitting portion 5 whose tip extends upward and a hook portion 27 corresponding to the lower end of the mounting wall 2, and the chain guide 1 is provided with the hook portion 26. It can be attached by fitting to each hook portion 26, 27. As the fixing method for preventing the lateral shift, the screw holes 8 and the drive unit 30 can be used as in the above-described embodiment. Further, when the chain guides 1 are arranged continuously rather than intermittently, both end portions 11 of the guide 1 can be configured obliquely as shown in FIG. 7. According to the configuration of the both end portions 11 of the slant, even if a plurality of units of the chain guide are misaligned with each other, it is possible to avoid deterioration of the chain traveling property.

The chain guide 1 having the structure shown in FIG. 8 has basically the same structure as that shown in FIG. 1, but the position regulating wall 13 has a different structure. That is, in this embodiment, the position regulating wall 13 is formed on one wall surface, and the through hole 15 for the screw 10 is formed on this wall surface.
