Description

[Detailed Description of the Invention] The present invention relates to a conveyor for conveying objects to be washed in a washing machine such as tableware using a conveyor.

As a conveyor for washing machines such as tableware, which transports and washes items on an endless conveyor,
The widthwise bars are lined up in the length direction of the conveyor, and each bar is attached with a plate extending in the length direction of the conveyor, or the support is erected on the surface side of the conveyor. However, since the surface of the conveyor is flat, the former is suitable for relatively low-height tableware such as plates, but it is suitable for relatively low-height tableware such as plates, but Items with high values are unstable and difficult to clean. The latter is suitable for cleaning items that can be washed while standing between the supports, such as dishes, or items that are relatively deep, such as pots, but it is not possible to stand between the supports and the diameter is relatively large. In the case of dishes, etc., they become unstable on the conveyor, resulting in the problem of incomplete washing.

This project solves the above problem. A conveyor is constructed by installing a shaft between a pair of endless chains, and an inverted E-shaped link is installed between the adjacent shafts at the tips of the supports at both ends. At the same time, the intermediate part is rotatably attached to the shaft in alternation with the links, and has a rotating body whose one end is connected to each other by a connecting bar, and the side protrusion of the arm that projects from the rotating body. The rotating body can be made horizontal or erect by passing the body under or over the guide rail.

To explain this with reference to the embodiment shown in the drawings, 1 is the fuselage, 2 is a tunnel-shaped cleaning chamber placed on the fuselage 1, and 3 is an endless object to be cleaned that is stretched in the length direction of the cleaning chamber 2. The transport conveyor 4 is a holding device for the object to be cleaned hanging down on the outgoing path of the conveyor 3, and can be bent arbitrarily in the same direction as the length direction of the conveyor 3. One end of the lengthwise direction is fixed to a rod or the like, and the other end is attached to a shaft so that it can be rolled up.The objects to be cleaned are sandwiched between this and the conveyor 3, and the cleaning liquid is applied to them. to prevent it from moving due to water pressure. Nozzles 5 are arranged above and below the forward path of the conveyor 3, and cleaning liquid is sprayed from these nozzles toward the forward path of the conveyor 3. Reference numeral 6 denotes a pair of endless chains that are parallel to each other, and a shaft 7 is installed between them in a suspended manner to constitute the conveyor 3. Reference numeral 8 denotes a nearly inverted E-shaped link attached to the conveyor 3 so as to protrude from the inner surface thereof, and the tips of mutually parallel support columns 9, 9 located at both ends of the link are rotatable around mutually adjacent shafts 7, 7. installed on. Reference numeral 10 denotes a stopper which is provided approximately parallel to the pillars 9, 9 in the middle thereof, and whose length is approximately the same as that of the pillars 9. Although it is suitable for the links 8 to be arranged in a staggered manner throughout the conveyor 3, there is no need to limit this configuration.

Reference numeral 11 denotes a rotating body whose intermediate part is attached to the shaft 7, alternating with links 8, and this is made up of two plates 1.
The ends of the shafts 2 and 12 are fixed to each other via a spacer 13, and the shaft 7 is rotatably inserted into a shaft hole 14 provided through the spacer 13. In this embodiment, the rotating body 11 is composed of two plates 12, 12, but it is also possible to attach the longitudinally intermediate portion of one plate 12 to the shaft 7.

Here, the two plates 12, 1 of the rotating body 11
2 has a length smaller than the distance between a pair of adjacent shafts 7, 7, and at least one has a length larger than the distance between the end of the link 8 and the central support, that is, the shaft 7 When the rotating body 11 is attached, the plate is made long enough so that it does not come into contact with the adjacent shaft 7 within its rotation range, and the plate is made longer than the distance between the end of the link 8 and the central support. As will be described later, the link is connected by a connecting bar at a position opposite to the central pillar of the link.

Reference numeral 15 denotes a connecting bar inserted into a hole provided at one end of the plate 12 of the rotary body 11, which connects the rotary bodies 11 attached to the shaft 7 to each other. The bar 15 is parallel to the shaft 7 and is provided at a position overlapping the top of the stopper 10. That is, the rotating body 11 has its connection bar 15
Since the side where the is attached becomes heavier, the connection bar 15
is supported by the top of the stopper 10 to maintain a horizontal state. Reference numeral 16 denotes an arm projecting from the shaft-attached portion of the rotary body 11 to the shaft 7, which is located on the end side of the shaft 7, toward the inner surface of the conveyor 3 in a direction substantially perpendicular to the plate 14; and 17, an arm. The roller is provided at the tip of the roller 16, and its axis is parallel to the axis 7. The roller 17 can also be replaced by a non-rotatable protrusion. 1
Reference numeral 8 denotes a pair of rails which are provided under the outgoing path of the chain 6 of the conveyor 3 and substantially parallel to the chain 6 over almost its entire length, on which the outgoing path of the chain 6 of the conveyor 3 is placed. There is. Reference numeral 19 denotes a guide rail arranged below the rail 18 and almost overlapping with it. This is arranged above the roller 17 of the arm 16 when it is almost vertical, and the roller 17 is placed between the guide rail 19 and the rail 18. There are intervals that allow for passage. Reference numeral 20 denotes a guide plate disposed at the end of the guide rail 19 opposite to the traveling direction of the conveyor 3 at almost the same height as the guide rail 19. The end on the guide rail 19 side is supported by a horizontal shaft, and the other The end side is movable up and down. Further, this guide plate 20 has a positional relationship and a size such that at least the upper surface of the other end on the side opposite to the guide rail 19 contacts the roller 17 on the side surface of the tip end of the arm 16 when the arm 16 is vertical within its rotation range. The end on the guide rail 19 side is pivoted.
21 is a sprocket provided at the end of the conveyor 3; 22 is an operating lever provided on the machine body 1 for rotating the guide plate 20; and 23 is an arc-shaped stopper provided inside the curved portion of the conveyor 3. This is arranged outside the rollers 16 at a position where they can be supported, and prevents the rotating body 11 from freely rotating. 24 is an object to be cleaned.

In this embodiment, the arm 16 is provided on the rotating body 11 located at both ends of the shaft 7, but it may also be provided on the rotating body 11 located in the center, or on all the rotating bodies 11.
1, and in that case, the guide rail 19 may be provided at a position corresponding to the roller 17.

The conveyor of the washing machine of the present invention has the above-mentioned configuration, and when the conveyor 3 is moved in the direction of the arrow in FIG.
The connecting bar 15 maintains a horizontal state by being placed on the top surface of the stopper 10 due to its weight,
Arm 16 is substantially vertical. Therefore, if the guide plate 20 is placed almost horizontally or upwardly as shown in FIG. moves through the cleaning chamber 2 with its outer surface being substantially flat.

Next, as shown in FIG.
7 is guided onto the guide rail 19 along the guide plate 20, the arm 16 is lifted, and the rotating body 11 fixed thereto is rotated. When the arm 16 is lifted by the guide rail 19, since the rotating bodies 11 of each shaft 7 are all connected to each other by the connecting bar 15, the ends of the rotating bodies 11 on the connecting bar 15 side are lifted and the conveyor It will be in a state where it is tilted in the direction opposite to the direction of travel in step 3. That is, at the same time that the plate 12 on the side of the connecting bar 15 with respect to the shaft 7 rises from the surface of the conveyor 3, the plate 12 on the opposite side faces the bottom surface of the conveyor 3. A recessed portion communicating with the width direction of the conveyor 3 is formed between the portions 10 and 10. The roller 17 is the guide rail 19
After passing above, the rotating body 11 returns to the horizontal state again due to its own weight.

As described above, the conveyor of the present invention only moves the guide plate 20 up and down, and allows the rotating body 11 to maintain a horizontal state or stand up.
It is possible to make the surface of the forward path flat and to form a recess in the width direction of the conveyor 3. Therefore, if the object to be cleaned has a relatively large diameter and a somewhat deep bottom, such as a rice bowl, and is suitable for cleaning while lying face down on a flat surface, the rotating body 11 should be placed in a horizontal position. The conveyor 3 can be made flat if the object to be washed is a plate, etc., which is suitable for washing in an upright position, or if the object is small in diameter and has a deep bottom, such as a cot, which is somewhat unstable. At this time, a recess is formed in the width direction of the conveyor 3 by rotating the rotating body 11 and inclining the plate 12, and a fifth
It is possible to wash objects of various shapes and sizes by standing up a dish, etc. as shown by the chain line in the figure, or by inserting the stopper 10 inside the pot and laying it down. It is.
