Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor which holds a large number of rollers, endless belts, and other transfer members between left and right side frames fixed by a gantry, and is particularly used in a processing line of a textile factory to insert a package. The present invention relates to a conveyor suitable for transporting relatively small articles such as a broken tray.

2. Description of the Related Art In a textile factory, yarn is processed into a package and conveyed between devices. The chemical fiber package cannot be placed horizontally to protect the yarn layer, and the package is conveyed while being inserted into the peg shaft of the tray so that the transfer robot can easily hold the package. There are two types of trays, a round tray that is erected around the peg shaft and a square tray that has the peg shaft protruding laterally. A conveyor is used to convey the tray. The tray is about 30 cm at the largest, and the package is about 15 kg at the heavy. In addition, the transport route has relatively many bends, and the straight part is 6 m at the longest.
There are many within. Therefore, a short conveyor is used as a standard so that it can be connected to various routes.

As such a tray conveyor, conventionally, the left and right side frames are fixed by a mount provided at appropriate places in the length 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 a tray runs 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 in 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. Also, the frame is fixed to the angle by welding or the like. When connecting shorter conveyors, a flange member is provided at the end of the conveyor and bolts are used for connection.

[0004]

However, since the above-mentioned general-purpose conveyor has a structure in which the conveyors are connected to each other by bolt fastening in the flange member, it is necessary to provide the flange member for connection, and the flange is required at the time of assembly. There is a problem that it takes time to align the members with each other.

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 provide a conveyor in which simultaneous connection of the conveyors can be performed easily and quickly. Is.

[0006]

In order to achieve the above-mentioned object, the conveyor of the present invention uses an extruding member having insertion grooves as left and right side frames for holding a conveying member that supports and conveys articles. The connecting member that extends between the members is inserted into the insertion groove and fixed.

[0007]

The connection is completed by simply inserting and fixing the connecting member between the extruding members by using the inserting groove of the extruded extruding member.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a side frame in a conveyor of the present invention, FIG. 2 is an assembly view of parts 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 slidable vertically. 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 a collar 22 via the roller receiving plate 1.
It is supported by 2 so as to be rotatable and slidable in the axial direction. A sprocket 23 that meshes with the chain 5 is also 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. 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 extruded member 30 of aluminum alloy 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 drawing, the L-shaped groove 31 for inserting and holding the roller receiving plate 12 from the end, the T-shaped groove 32 for fixing the stopper for the roller receiving plate 12, and the upper chain support plate 14 are inserted and held from the end. L-shaped groove 33 for inserting, the L-shaped groove 34 for inserting and holding the lower chain support plate 15 from the end, the stepped groove 35 for inserting the protective plate 13 from above, the upper groove for vertically inserting the cover plate 16 36 and lower groove 37, T-shaped groove 38 for fixing both end sprocket holders, T-shaped grooves 39, 40 for fixing upper and lower frames, motor boxes, etc., cable 17, pipe 1
A recess 41 for accommodating 8 is provided. In particular,
Since the tip end portions of the roller receiving plate 12, the upper chain supporting plate 14, and the lower chain supporting plate 15 are bent in an L shape corresponding to the L-shaped grooves 31, 33, 34, the L-shaped grooves 31, 33, 34 are formed. On the other hand, although it can be inserted only from the end, it is retained as it is.

Further, the supporting structure of the roller 4 will be described. The roller receiving plate 12 is provided with an upper and lower cut 45 having an open top.
And a horizontal cut 46 communicating with the upper and lower cuts 45, and a recessed hole 47 below the upper and lower cuts 45. When the portion of the fixed shaft 20 of the roller 4 is inserted from the vertical cut 45 and slid to the inside of the horizontal cut 46, and then the clip 48 with the convex portion is inserted under the vertical cut 45 and engaged with the recessed hole 47, the roller 4 Is fixed. In addition,
An opposite portion (not shown) of the roller 4 slides the collar into a large size vertical cut and a horizontal cut. As described above, the rollers 4 can be incorporated in order from the top, and there is no need to perform the procedure of previously incorporating the rollers 4 into the roller receiving plate 12 and then inserting the rollers.
Easy to install.

After the roller 4 is assembled, the protective plate 1

Can be removed. Further, the protection plate 13 is not only a safety cover, but its tip is a bent portion 13a, and the tray 1 running on the roller 4 as shown in FIG.
It is also used as a guide for 9.

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, when the roller receiving member 12 is made longer than the extruding member 30, the roller receiving member 12 protrudes from the extruding member 30. When the protruding portion is inserted into the second extruding member 30 ', the extruding member 30,
30 'can be connected. Not only when the roller receiving member 12 is used as a connecting member, female screw holes are provided at both ends of a rectangular plate which is inserted into the T-shaped groove 40, and the rectangular plate is inserted across the pushing members 30 and 30 '. The rectangular plate can also be easily connected by fixing it with a spacer and a bolt that abuts the upper surface of the extruding member 30, 30 '.

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 is simply T
There is a possibility that the position will shift if it is simply inserted into the groove 31. Therefore, stoppers 51 are provided on both ends of the roller receiving plate 12.
Then, the stopper 51 is fixed with a square nut 52 and a bolt 53 which are inserted into the T-shaped groove 32. The both-end sprocket 6 is axially supported by the holder 55, and the holder 55 is fixed to the extruding member 30 by the square nut 56 and the bolt 57 inserted into the T-shaped groove 38. Further, the pedestal 2 is fixed to the lower surface of the extruding member 30 with a square nut 58 and a bolt 59 inserted into the T-shaped groove 39. In the upper and lower two-stage conveyor, the upper pedestal 2a is fixed to the upper surface of the extruding member 30 with a square nut 60 and a bolt 61 which are inserted into the T-shaped groove 40, as illustrated. 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, the procedure for assembling the conveyor having the above structure will be described with reference to FIG. First, the extruded member 1 having a length required for the conveyor is cut in advance. This 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 pivotally 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 rollers 4 are inserted into the roller receiving plate 12 in order from the top, and the rollers 48 are fixed by the clips 48. It is not necessary to install the roller in the roller receiving plate 12 in advance, and the roller can be installed in the work of assembling 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. And the protective plate 13

In addition, a tray stopper or a tray side-loading cylinder (not shown) is fixed by using an appropriate T groove, and a cable 17 and a pipe 18 for operating these are provided on the side surface of the extruded member through a hole appropriately opened 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. When the insertion groove easily provided in the extruded member is utilized, 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 are 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.

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