DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 shows an upstream-side conveyor 4 and a downstream-side conveyor 6, and a transfer member between the conveyors 4 and 6 according to an embodiment of the present invention (indicated by a reference numeral 2 as a whole). FIG. 2 is a longitudinal sectional view taken along a conveyor conveyance direction (the direction of arrow A in FIG. 1). FIG. 2 shows the delivery member 2 installed between the conveyors 4 and 6, and is a cross-sectional view along the line II-II in FIG.

The upstream conveyor 4 and the downstream conveyor 6 arranged in series have a plurality of pulleys 4a, 6a, respectively.
(The others are not shown) wrapped around the conveyor belt 4b,
6b, the two conveyors 4, 6 shown in FIG.
The delivery member 2 according to the present invention is installed at the connection part of the present invention. In this example, a pulley is arranged at a connection portion where the downstream end of the upstream conveyor 4 and the upstream end of the downstream conveyor 6 face each other in order to minimize the gap between the conveying surfaces 4c and 6c of both conveyors. Instead, a fixed guide having a curved surface is arranged.

Next, the structure of the delivery member 2 between the conveyors will be described. The two conveyors 4, 6 are designed to convey a large amount of articles (not shown) such as containers at a time, and have a very large width (a size in a direction orthogonal to the conveyor conveyance direction A). . Therefore, the delivery member 2
2 has a wide width over the entire width of the conveyors 4 and 6, as shown in FIG.

The delivery member 2 includes a plate portion 8 having a sliding surface having substantially the same height as the conveying surface 4c of the upstream conveyor 4 and the conveying surface 6c of the downstream conveyor 6, and the plate portion 8 is moved from the lower surface side. And a supporting body 10 for supporting.

The support 10 has a main body 16 fixed between the side walls 12 by a plurality of bolts 14, and a thick plate portion 18 sandwiched between the main bodies 16 and capable of moving up and down relatively.
And a thin plate portion 20 sandwiched and fixed above the thick plate portion 18. The main body 16 is fixed between the side walls 12 by the bolts 14 as described above, but has a slight clearance with respect to the bolts 14 and can be slightly moved up and down.

A plurality of mounting plates 22 are provided on the lower surface of the main body 16.
Has been fixed. On the other hand, screw blocks 24 are fixed to both side walls 12, respectively. Bolts 26 for vertically moving the main body are inserted and screwed into the through screw holes formed in each of the screw blocks 24 from the lower surface side. The lower plate 16 is in contact with the mounting plates 22 provided at both ends from below. Therefore, by rotating the bolt 26, the entire main body 16 can be moved up and down.

A lifting bolt 28 and a lowering bolt 30 for raising and lowering the thick plate portion 18 with respect to the main body portion 16 are screwed to the mounting plate 22. Lifting bolt 28
The lower end of the lower bolt 30 contacts the lower surface of the thick plate portion 18.
Are screwed to the thick plate portion 18 and each bolt 2
The thick plate portion 18 can be raised or lowered by rotating 8, 30. A plurality of lifting bolts 28 and lowering bolts 30 are provided at appropriate intervals on the lower surface side of the thick plate portion 18. The plate 28 can be partially pushed up or down. By such an operation, when the height of the sliding surface of the plate portion 8 is not uniform or the like, the height can be partially adjusted to make the plate portion 8 flat.

The thin plate portion 20 which is vertically fixed to the upper end of the thick plate portion 18 is, as shown in FIG.
a is bent in an L-shape, and an auxiliary plate 32 whose front end 32a is bent in an L-shape in the opposite direction is fixed to the back side thereof. These integrated thin plate parts 2
0 and the auxiliary plate 32 constitute a rail portion 34 that engages with the plate portion 8 and supports the plate portion 8 so that the plate portion 8 can be moved in a direction orthogonal to the conveyor conveyance direction A.

The plate section 8 is used when transferring articles such as containers from the upstream conveyor 4 to the downstream conveyor 6.
An acute angle is formed between a horizontal plane portion 8a constituting a sliding surface on which these articles move while sliding, and both sides (the side facing the upstream conveyor 4 and the side facing the downstream conveyor 6) of this plane portion 8a. Folded side portions 8b, and flat lower surface portions 8c obtained by horizontally bending the lower ends of the side portions 8b on both sides inward.
And The flat portion 8a of the plate portion 8 is short on the downstream side (left side in the figure), and slightly longer on the upstream side than on the downstream side. The transfer member 2 disposed between the plurality of conveyors 4 and 6 has a plate portion 8 when the length in the transport direction increases.
It is preferable that the length is as short as possible because there is a risk that the articles sliding on the upper side may stop on the way. However, the upstream side of the plate portion 8 is extended so that the transfer from the upstream conveyor 4 can be performed smoothly. On the other hand, the downstream side is shortened because there is no risk of articles being caught during transfer. That is, the surface of the delivery member 2 on which the article slides (the flat portion 8a).
Is required to be as short as possible, but if the distance between the upstream conveyor 4 and the upstream conveyor 4 is large, the transfer cannot be performed smoothly. Therefore, the flat portion 8a is moved from the intermediate position of the connecting portion between the upstream conveyor 4 and the downstream conveyor 6. Are also offset to the upstream side. With such a configuration, it is possible to smoothly deliver the article and to eliminate the possibility that the article stops during the delivery. Note that the plate section 8 is not limited to a configuration in which the upstream side is extended, and it goes without saying that the present invention is established even if the upstream side and the downstream side have the same size.

As described above, a space is formed inside the plate portion 8 which is bent in a substantially inverted trapezoidal shape, and the space is formed by the plate thickness of the bent portions 20a and 32a at the tip of the rail portion 34. The height of the gap H is substantially the same as or slightly larger than that of the thin plate portion 20 and the auxiliary plate 32. have. Therefore, when the plate portion 8 is engaged with the rail portion 34, the plate portion 8 is restricted from moving up and down relative to the rail portion 34, and is moved in the direction in which the conveyors 4 and 6 convey articles (the direction of arrow A). Moving is also regulated. On the other hand, the plate portion 8 can move in the longitudinal direction of the rail portion 34 (the direction orthogonal to the transport direction A of the conveyors 4 and 6). In addition, the plate part 8 may be constituted by one member in the longitudinal direction, or may be constituted by a plurality of divided members.

The operation of the delivery member 2 between the conveyors according to the above configuration will be described. When an article such as a container conveyed by the upstream conveyor 4 reaches the downstream end, the transfer member 2 is moved from above the conveying surface 4c of the conveyor belt 4b.
And moves on the flat sliding surface 8a of the plate portion 8 and slides on the sliding surface 8a to advance on the conveying surface 6c of the downstream conveyor 6. Thus, the upstream conveyor 4
Since the plate portion 8 of the delivery member 2 disposed therebetween is made of resin when transferring from the to the downstream conveyor 6,
It can slide and move smoothly with little frictional resistance. Therefore, there is no possibility that the article is caught and fall down, and the last article to be conveyed does not remain on the plate portion 8 and can smoothly slide and move onto the downstream conveyor 6. .

In this embodiment, since the plate portion 8 constituting the sliding surface 8a of the delivery member 2 is made of resin, the article can be moved smoothly and the delivery between the two conveyors 4, 6 can be performed. However, since the wear is greater than in the case of the conventional metal, it is necessary to replace the metal in a shorter time. However, in the above-described embodiment, since the plate portion 8 is not fixed to the support 10 but is merely engaged with the rail portion 34 at the upper end of the support 10, the plate portion 8 is moved along the rail portion 34 in the conveyor conveyance direction A. The plate portion 8 can be replaced very easily.

In the above embodiment, a rail portion 34 is formed at the upper end of the support 10 by integrally integrating the thin plate portion 20 having the tip 20a bent horizontally and the auxiliary plate 32 having the tip 32a bent in the opposite direction. The plate portion 8 is supported by the support 10 by engaging the plate portion 8 bent in a substantially inverted trapezoidal shape with the rail portion 34. However, the plate portion 8 is not limited to the shape described above. It is needless to say that the vertical movement and the movement in the front and rear direction of the conveyor conveyance direction A can be restricted, and the engagement and support can be performed so as to be movable in the direction orthogonal to the conveyor conveyance direction A. Further, the connecting portions of the two conveyors 4 and 6 have a structure in which the conveyor belts 4b and 6b are inverted by a fixed guide. However, a normal pulley may be provided to invert the conveyor belts 4b and 6b.

[0019]

As described above, according to the present invention, a delivery member arranged between a plurality of conveyors for delivering articles is constituted by a plate portion and a support, and the plate portion is moved in the conveyor transport direction. The plate portion can be replaced very easily because it can be moved in the orthogonal direction and can be attached and detached. In addition, since the plate portion is made of resin, the article can move smoothly, and it is possible to prevent the article from overturning or remaining on the delivery member.
