Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor for conveying articles, and more particularly to a conveyor having a predetermined strength and capable of being easily cleaned.

[0002]

2. Description of the Related Art FIG. 8 is a perspective view showing a conventional conveyor. The figure shows the back side of the conveyor. The conveyor 51 includes a pedestal 54, drive rollers 55a and 55b provided at both ends of the pedestal 54, and the rollers 55a and 5b.
It is composed of an endless belt 56 between 5b.

In the above conveyor 51, a pedestal 54 is formed by bending a plate material to form an upper surface 54a and side plates 54b on both sides. An article conveyed by a belt 56 is placed on the upper surface 54a of the cradle 54. A reinforcing member 55 is provided to give the cradle 54 a predetermined strength. For example,
As shown in the drawing, a substantially U-shaped angle member is continuously provided between the pair of side plates 54b.

[0004]

However, in the above-described conventional conveyor 51, it is difficult to clean the foreign matters because the foreign matters are likely to enter from the mating surfaces of the plates of the receiving table 54 and the reinforcing member 55. The mating surfaces of the plates are joined by welding or the like. Since the inside of the reinforcing member 55 is hollow, there is a gap in the joint surface, and if a foreign matter enters through this gap, this foreign matter cannot be removed.

This conveyor 51 is sometimes used in a weighing device for weighing foods, and in such a case,
Bacterial reproduction due to foreign matter was sometimes a problem. Further, since the reinforcing member 55 is attached to the pedestal 54, the weight of the whole is increased. In particular, since the weighing device is configured to weigh the conveyor 51 and the article together and calculate the mass of the article by subtracting the weight of the conveyor 51 in the calculation unit, making the weight of the conveyor 51 easily causes a weighing error. . Further, the cradle 54 is difficult to assemble and disassemble after the assembly, so that replacement of parts and cleaning of each part cannot be performed.

The present invention has been made in order to solve the above-mentioned problems, and has a predetermined strength, has a small number of faces for fitting the parts constituting the conveyor, is easy to assemble and disassemble, and is excellent in cleanability.

A front view of the supporting rod 17 is shown in FIG. 3 (c). The support rod 17 is formed in a cylindrical shape having a shaft diameter that can be inserted into the through hole 20b of the outer receiving portion 15A. Support 17
Both end portions 17a are formed to have a larger diameter than the fixing opening hole 20a of the outside receiving portion 15A, and a fixing screw hole 18a is formed therein. A fixing screw 18b is attached to the screw hole 18a. Also, locking recesses 19 are formed in the locking positions of the side plates 15b of the inner receiving portion 15B when viewed in the axial direction. This locking recess 19
Is formed in a diameter such that the locking groove 26 can be locked. That is, the shaft diameter of the support rod 17 is formed larger than the diameter of the locking groove 26.

Assembly of the cradle 10 having the above-mentioned structure will be described with reference to FIGS. FIG. 4 is a diagram showing an assembly procedure. The figure (a) is a top view, the figure (b) is a front view, and the figure (c) is a side view. First, the inner receiving part 1
Assemble 5B and supporting rod 17. As shown in the figure, the two inner receiving portions 15B are arranged in parallel at a predetermined interval. Then, after the first supporting rod 17 is locked in one locking groove 26 portion of the inner receiving portion 15B, the second supporting rod 17 is fixed to the inner receiving portion 15B.
It is carried out by locking it in the locking groove 26 portion of.

That is, as shown in the partially enlarged perspective view of FIG. 5, the locking recess 19 of the support rod 17 is positioned in the guide groove 26b of the inner receiving portion 15B and is inserted from below. After this,
The support rod 17 is slid along the introduction groove portion 26a so as to be locked and fixed to the inner portion of the locking groove 26 (the upper portion of the retaining piece 26c). The introduction groove portion 26a faces the relative direction on the one side and the other side, and the support rod 17 slides in the first and second slide directions so that the sliding directions are separated from each other. As a result, as shown in FIG. 4, the two inner receiving portions 15B are arranged at predetermined predetermined intervals by the supporting rod 17 extending in the orthogonal direction.

After that, the plan view of FIG. 6A and the same FIG. 6B are shown.
As shown in the front view of FIG.
Each of the outer receiving portions 15A is inserted and attached. That is, the outer receiving portion 15A is inserted into the supporting rod 17 from the side plate 15bb side provided with the through hole 20b. This allows
The end portion 17a of the support rod 17 contacts the inner surface of the other side plate 15ba.

In this state, the fixing opening hole 2 of the side plate 15ba
A fixing screw 18b is screwed and fixed from the 0a portion to the end portion 17a of the supporting rod 17. As a result, as shown in FIG. 1, the pedestal 1
0 is assembled and completed. In this assembled state, the receiving portions 15A and 15B are supported by the supporting rod 17 with a predetermined strength. The two inner receiving portions 15B provided on the inner side are positioned on the retaining pieces 26c by being locked in the locking grooves 26 with respect to the fixed supporting rod 17 which is fixed by the outer receiving portions 15A. is doing. As a result, in this assembled state, the inside receiving portion 15B does not drop off from the support rod 17 or slip off above.

Further, the fixing opening hole 2 of the outer receiving portion 15A
0a, the through hole 20b, and the locking groove 26 of the inner receiving portion 15B.
Are provided at the same position, that is, at the same height position with respect to the upper plate 15a. As a result, the supporting rod 17
Then, only by fixing the outside receiving portion 15A and the inside receiving portion 15B, the plurality of upper plates 15a are at the same height position. As a result, the upper surface 10a of the pedestal 10 becomes a smooth surface, and the conveyance movement of the belt 12 is not hindered.

As described above, since the pedestal 10 is composed only of the plurality of receiving portions 15A and 15B arranged at a predetermined distance from each other and the supporting rod 17 connecting and fixing them, the weight reduction can be achieved. . Further, since the receiving portion extends along the carrying direction and the supporting rod 17 is arranged in the direction orthogonal to the carrying direction, it has a predetermined strength. Since it has a predetermined strength, no reinforcing member is required, and since it is lightweight, it is possible to reduce the weighing error in the weighing unit.

By the way, the assembled pedestal 10 can be easily disassembled in the reverse order of the assembling procedure. The pedestal 10 can increase or decrease the number of parts in the length direction (conveyance direction) and the width direction according to the required area, not limited to the number of parts.

For example, when the pedestal 10 is formed longer in the longitudinal direction, one or more connecting rods may be bridged between the two supporting rods 17. In this case, the through hole is opened in the inner receiving portion 15B, the connecting rod is inserted, and both ends of the connecting rod are fixed by screws with the outer receiving portion 15A. As a result, a predetermined strength can be maintained even when the pedestal 10 is formed long in the longitudinal direction.

If it is desired to widen the width of the pedestal 10, the number of the inner receiving portions 15B is increased (for example, three or more). The supporting rod 17 has a length corresponding to this width, and a plurality of engaging recesses 19 for engaging with the side plates 15b of the inner receiving portions 15B may be formed at predetermined positions. Similarly, when it is desired to narrow the width direction of the pedestal 10, the number of the inner receiving portions 15B is reduced (for example, one). The supporting rod 17 has a length corresponding to this width, and the engaging recess 19 for engaging with the side plate 15b of the inside receiving portion 15B is formed with a groove at a substantially intermediate position.

From this, even if the conveyor 1 is assembled and operated, the width can be easily changed to the required width when the length direction of the pedestal 10 is unchanged. In this case, it suffices to replace the supporting rod 17 with a corresponding length and adjust the number of the inner receiving portions 15B according to the width. As a result, the parts that have been used before can be commonly used, and various changes can be dealt with without wasting the parts. Further, in the conveyor 1 having the above-described configuration, the parts can be shared and the assembling work can be shared in the manufacturing line, and the manufacturing efficiency can be improved.

Next, a second embodiment of the present invention will be described.
In this embodiment, the configuration of the inside receiving portion 15B is changed. FIG. 7 is a side view showing the inside receiving portion 15B in this second embodiment. As shown in the figure, the structure of the locking groove 26 is changed. This locking hole 36
A groove similar to the locking groove 26 is formed at the same position as the opening hole 20 formed in the outside receiving portion 15A (a position indicated by a chain line in the drawing), and a side portion of the locking groove 36 (the above-mentioned locking groove). (Transfer direction)
An introduction groove 36a for inserting the support rod 17 is formed in the opening.

The locking hole 36 has a shape in which two large and small circular openings are connected at the center. Introductory groove 36a as shown
Are arranged in directions opposite to each other with respect to the transport direction with the locking hole 36 as the center. The introduction groove portion 36a has a support rod 1
7 is formed with an opening having a diameter allowing insertion of the locking groove 36.
Is opened to a diameter such that the locking recess 19 of the supporting rod 17 can be locked.

As described above, the locking groove 26 of the first embodiment is used.
As compared with the configuration in which the guide groove portion 26b communicates with the lower portion of the side plate 15b and opens as described above, the only difference is that the guide groove portion 26b does not open, and the attachment of the support rod 17 is different, and It has the same effect as the embodiment. The locking groove 26 and the locking hole 36 both have a function of a locking portion that locks on the supporting rod 17.

[0033]

Since the conveyor of the present invention has a constitution in which a plurality of receiving portions are connected and fixed by orthogonal supporting rods, it has a predetermined strength and there are very few surfaces where the parts constituting the conveyor are mated with each other. Easy to clean, easy to assemble and disassemble. Further, the number of parts is small, the weight can be reduced, and the parts can be disassembled for thorough cleaning.
