Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyor that holds a large number of rollers, endless belts, and other transfer members between left and right side frames that are fixed by a gantry, and is particularly used in a processing line of a textile factory, such as a tray into which a package is inserted. The present invention relates to a conveyor suitable for conveying relatively small articles.

[0002]

[Prior art]

 In a textile factory, yarn is processed into a package form and transported between devices. The compound fiber package cannot be placed horizontally to protect the yarn layer, and the package is transported while being inserted into the peg axis of the tray so that the transfer robot can easily hold the package. There are two types of trays: a round tray with the peg axis standing upright and a square tray with the peg axis protruding laterally. A conveyor is used to convey the tray. The maximum tray size is around 30 cm, and the heavy package size is around 15 kg. In addition, the transportation route has relatively many bends, and the straight part is often within 6 m at the longest. Further, even if it is small and short, protective plates for the driving portion of the roller are provided on both sides.

As such a tray conveyor, conventionally, the left and right side frames are fixed by a gantry provided at appropriate places in the longitudinal direction, a large number of rollers are held between the both side frames, and the rollers are rotationally driven. A general-purpose conveyor in which trays run on rollers is used. The side frame of this general-purpose conveyor uses an angle formed by bending a plate material. In order to hold the roller at this angle, a large number of bolt holes are formed in the angle, and bolts are passed through the bolt holes to hold the roller. The mount is fixed to the angle by welding. Further, the protective plate for the driving part of the roller is fastened to the side frame by using a large number of bolts.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned general-purpose conveyor, the protective plate is fastened with a large number of bolts, so that there is a problem that it takes time to remove the roller drive unit when inspecting it. In addition, there is also a problem that it takes a lot of assembly man-hours because the bolts are fastened.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to easily and quickly remove a protective plate from a transfer member such as a roller. The goal is to provide a conveyor that reduces the number of assembly steps.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the conveyor of the present invention uses extruding members as the left and right side frames that hold the transfer members that support and transfer the articles, and the grooves into which the protective plates of the transfer members can be inserted from above are extruded. The protective plate is fixed by a spacer provided on the member and pressed into the gap between the groove and the protective plate.

[0007]

[Action]

 The protective plate can be assembled by simply inserting the protective plate into the insertion groove of the extruded extruded member from above and pushing the spacer into the gap between the groove and the protective plate, and then removing the spacer to remove the protective plate.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a side frame of a conveyor of the present invention, FIG. 2 is an assembly drawing of a conveyor, and FIG. 3 is a sectional view of a roller. First, the entire conveyor will be described with reference to FIGS. 2 and 3, and then each part will be described.

First, in FIG. 2, the left and right side frames 1 are supported by pedestals 2 and 3, and a large number of rollers 4 are arranged between the side frames 1. The roller 4 is driven by a chain 5, and the chain 5 is wound between sprockets 6 and 7 at both ends, and travels by a drive sprocket 10 connected to a motor 11 via guide sprockets 8 and 9. Further, a roller receiving plate 12, a protective plate 13, an upper chain supporting plate 14, a lower chain supporting plate 15, etc., which support a large number of rollers 4, are attached to the side frame 1. The tension of the chain 5 can be easily adjusted by making the guide sprockets 8 and 9 movable left and right, or by making the motor horizontally and making it vertically slidable. In FIG. 3, the roller 4 is axially supported by a fixed shaft 20, one end of the fixed shaft 20 has a slit 21 and is fitted and supported by a roller receiving plate, and the other end is supported by the roller receiving plate 12 via a collar 22. It is supported so that it can rotate and slide in the axial direction. A sprocket 23 that meshes with the chain 5 is also axially supported by the fixed shaft 20, and the rotational force of the sprocket 23 is transmitted to one end of the roller 4 by a friction plate 24. A compression spring 26 acts on the other end of the roller 4 via a sliding plate 25 having a small friction, and the degree of compression of the compression spring 26 can be adjusted by a nut 27. The compression spring 26 functions as a torque limiter, and when an excessive force acts on the roller 4, the friction plate 24 causes the sprocket 23 to idle, so that the driving force is not transmitted to the roller 4.

Next, in FIG. 1, an aluminum alloy extruded member 30 is used as the side frame 1, which is different from the conventional general-purpose conveyor. The extruding member 30 is extruded by a press using a mold. Therefore, by forming the mold into a predetermined shape, it is possible to inexpensively obtain the extruding member 30 having a desired groove and having the same cross-sectional shape anywhere. Then, as shown in the figure, an L-shaped groove 31 for inserting and holding the roller receiving plate 12 from the end, a T-shaped groove 32 for fixing the stopper for the roller receiving plate 12, and an upper chain supporting plate 14 for inserting and holding. L-shaped groove 33 for insertion, L-shaped groove 34 for inserting and holding the lower chain support plate 15 from the end, stepped groove 35 for inserting the protective plate 13 from above, and for inserting the cover plate 16 up and down. Upper groove 36 and lower groove 37, T-shaped groove 38 for fixing sprocket holders on both ends, T-shaped grooves 39, 40 for fixing upper and lower frames and motor boxes, cables 17 and pipes 18 for storing A recess 41 is provided. Particularly, since the tip ends of the roller receiving plate 12, the upper chain supporting plate 14, and the lower chain supporting plate 15 are bent in the L-shape in correspondence with the L-shaped grooves 31, 33, 34, the L-shaped groove 31 , 33, 34 can be inserted only from the end, but when inserted, they are held as they are.

Further, the support structure of the roller 4 will be described. The roller receiving plate 12 is provided with upper and lower cuts 45 having an open upper side, a horizontal cut 46 communicating with the upper and lower cuts 45, and a concave hole 47 below the upper and lower cuts 45. The part of the fixed shaft 20 of the roller 4 is inserted from the upper and lower cuts 45 and slid to the inside of the horizontal cut 46, and then the clip 48 with the convex portion is inserted under the upper and lower cuts 45 and engaged with the recessed hole 47. LA4 is fixed. In addition, on the opposite side portion (not shown) of the roller 4, the collar is slid into a vertical cut and a horizontal cut having large dimensions. In this way, the rollers 4 can be installed in order from the top, and there is no need to carry out the procedure in which the rollers 4 are previously installed in the roller receiving plate 12 and then inserted, and the installation is simple.

After the roller 4 is assembled, the protective plate 13 is inserted into the stepped groove 35 from above, and the spacer 49 is pushed into the gap between the protective plate 13 and the stepped groove 35 to fix the protective plate 13. The spacer 49 is made of, for example, hard rubber or plastic and is formed into an L-shape, and is pushed into a key portion in the longitudinal direction. Since it is L-shaped, the protective plate 13 can be easily removed by prying it with a screwdriver as shown by the arrow 50 in FIG. Further, the protection plate 13 is not only a safety cover but also has a bent portion 13a at its tip, and also serves as a guide for the tray 19 traveling on the roller 4 as shown in FIG.

As described above, the extruding member 30 of FIG. 1 has various grooves, and it is easy to connect the extruding members 30 in the longitudinal direction by using these grooves. For example, if the roller receiving member 12 is made longer than the extruding member 30, the roller receiving member 12 protrudes from the extruding member 30. By inserting this protruding portion into the second extruding member 30 ', the extruding members 30 and 30' can be connected. Not limited to the case where the roller receiving member 12 is used as the connecting member, female screw holes are provided at both ends of the rectangular plate to be inserted into the T-shaped groove 40, and the rectangular plate is spread over the pushing members 30 and 30 '. It can also be easily connected by inserting it and fixing the rectangular plate with a spacer and bolts that contact the upper surfaces of the extruding members 30 and 30 '.

Another assembly part of the conveyor will be described with reference to FIGS. 4 and 5. 4 is a perspective view of a main part of the conveyor, and FIG. 5 is a sectional view taken along line AA of FIG. The side frames 1 shown in FIG. 4 are arranged symmetrically, and the right side frame (not shown) is symmetrical to the left side frame 1. The roller receiving plate 12 in which the roller 4 is incorporated may be displaced if it is simply inserted into the T-shaped groove 31. Therefore, the stoppers 51 are placed on both ends of the roller receiving plate 12, and the stoppers 51 are fixed by the square nuts 52 and the bolts 53 inserted into the T-shaped grooves 32. The sprockets 6 on both ends are axially supported by a holder 55, and the holder 55 is fixed to the pushing member 30 by a square nut 56 and a bolt 57 which are inserted into the T-shaped groove 38. The pedestal 2 is fixed to the lower surface of the extruding member 30 with a square nut 58 and a bolt 59 which are inserted into the T-shaped groove 39. In the upper and lower two-stage conveyor, as shown in the figure, the upper pedestal 2a is fixed to the upper surface of the extruding member 30 by the square nut 60 and the bolt 61 inserted into the T-shaped groove 40. As described above, by using the T-shaped grooves 38, 39, 40, various members can be fixed to the extruding member 30, and for example, a tray stopper, a motor box or the like can be fixed to the extruding member 30 at appropriate places.

Next, a procedure for assembling the conveyor having the above structure will be described with reference to FIG. First, the extrusion member 1 having a length required for the conveyor is cut in advance. The extrusion member 1 does not need to be processed with a bolt hole for fixing, and the pedestal 2 is fixed as it is with the square nut 58 and the bolt 59. Then, the roller receiving plate 12 and the upper and lower chain supporting plates 14 and 15 are inserted from the ends of the L-shaped grooves 31, 33 and 34. The chain 5 is placed on the upper and lower chain support plates 14 and 15, and the holder 55, on which the sprockets 6 at both ends are axially supported, is fixed by the square nut 56 and the bolt 57 to complete the winding of the chain 5. Then, as shown in FIG. 1, the roller 4 is inserted into the roller receiving plate 12 in order from the top, and the roller 48 is fixed by the clip 48. Since it is not necessary to install the roller in the roller receiving plate 12 in advance, the roller can be installed in the assembly work of the conveyor body, and the setup is reduced. Further, both ends of the roller receiving plate 12 are fixed by the stoppers 51 shown in FIG. Then, the protective plate 13 is inserted into the two-step groove 35 from above, and the spacer 49 is pushed in and fixed as shown in FIG. In addition, a tray stopper and a tray lay-out cylinder (not shown) are fixed using appropriate T-grooves, and cables 17 and pipes 18 for operating these are provided on the side surface of the extruding member through holes appropriately formed by on-site processing. It is retracted and stored in the recess 41. Then, the upper end of the cover plate 16 of FIG. 1 is inserted into the upper groove 36 and pushed up, and the lower end of the cover plate 16 is inserted into the lower groove 37 so as to be pushed down to complete the assembly. By using the insertion groove easily provided in the extruded member, the assembly is simplified. Further, as shown in FIG. 5, the cable 17 and the pipe 18 are housed in the recess 41, and since the cover plate 16 has the lid, the cable 17 and the pipe 18 are physically protected without being seen from the outside, so that the wiring work and the piping work can be simplified. Furthermore, if the spacer 49 is removed with a screwdriver or the like, the protective plate 13 can be easily removed and maintenance is easy. Further, by using the insertion groove of the extruding member, it is possible to easily connect two or more extruding members.

Although the above-mentioned conveyor has been described using the roller 4 as the transfer member, it can be easily assembled by using the extruding member even when the belt is used as the transfer member. Also, the two-stage conveyor for feeding and returning can be easily assembled by combining the extrusion member and the gantry.
