Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor for conveying washed and dehydrated cake-like linen to a plurality of dryers.

In recent years, the processing efficiency of plants that automatically process linen washing, dehydration, and drying in an integrated and automatic assembly line has increased significantly, but there is an imbalance in the processing capacity of dehydrators and dryers, and problems arise between the two. The method of conveying the materials is a technical bottleneck.

That is, as shown in Fig. 1, the dewatering machine 1 dehydrates the noodles and the noodles 2 are sent to the dryer 3, but the outlet 3a of the dryer 3 has a considerable ground clearance h to dry the noodles and send the noodles to the next process. Accordingly, the ground height h' of the input port 3b is also considerably high. For this reason, it is necessary to lift the waste that comes out from the outlet la of the dehydrator 1 to the dryer input port 3b at a height h' above the ground. Conventionally, a belt conveyor 4 is installed between the dewatering machine 1 and the dryer 3 to convey linen, but the belt conveyor 4 is relatively difficult to transport because the belt conveyor 4 is limited to an extent that prevents the IJ linens on the compare belt from slipping. The length must be .

As a result, since the distance w between the dehydrator 1 and the dryer 3 must be large, the installation area of the entire apparatus is large. Furthermore, with current technology, the time required for drying work is significantly longer than the time required for dewatering work. In many cases, it is necessary to combine several dryers with a dryer.

However, the use of the conventional inclined belt conveyor as described above has the following problems. That is, FIG. 2 shows the planar arrangement of dewatering and drying equipment, in which the dehydrator 1 receives washed linen from the washing machine 5, dehydrates it, and then
A diagonal belt conveyor 4 sends it to a dryer 3. In this case, in order to provide one more dryer, it is conceivable to install the dryer 3' at the position of the imaginary line A and to make the mirror belt conveyor 4 movable in the directions of arrows B and C. . If this method is used, A′
A dryer can be added to the position of , but the imaginary line D
, Even if a dryer is installed at position 〇, linen cannot be sent. Furthermore, it is not possible to construct fixed equipment such as water and gas piping or electrical wiring near the ground surface in the passage 8 area where the mirror-slanted belt conveyor 4 is moved, and even if things are temporarily Since it must be removed when the belt conveyor 4 moves, a large dead space results. In view of the problems in the conventional forehead diagonal belt conveyor as explained above, the present invention has been developed to
The width of the area can be significantly reduced, and even if fixed equipment is built horizontally or objects are placed on the ground within the passage area, transport is not obstructed, and even if the area is lined up on both sides across the passage. To provide a conveyor device for dewatering and drying equipment capable of feeding linen even to a plurality of installed dryers.

In order to achieve the above object, the present invention includes an elevated running rail provided above a passageway extending over the outlet of a dehydrator and the inlet of a plurality of dryers, and a self-propelled running rail suspended on the above-mentioned running rail. a vertically reversible horizontal belt conveyor that can be driven up and down while being guided by the suspension frame; and a running guide rail for the suspension frame installed at a distance from the ground on the side of the passageway. The suspension frame is characterized in that it is configured to be able to run without interfering with obstacles on the ground.

Next, an embodiment of the present invention will be described with reference to FIGS. 3 to 5. FIG. 3 shows a planar arrangement of dewatering and drying equipment in an embodiment of the present invention, in which the washing machine 5, the dehydrator 1 and the dryer 3 are similar to the machines described above.

Directly facing the outlet la of the dehydrator 1, a dryer 3 is disposed across a passage 8 along which a horizontal belt conveyor 9 according to the present invention moves. The dryer 6 faces the passage E'.
, 7 are arranged in parallel, and each dryer 3, 6, 7 has its respective input port facing the passage E'. An elevated traveling rail 8 is provided along the passage E'.

8c and 8d are supports of the traveling rail 8.

A lower guide rail 18 is provided near the ground surface along the path E' and close to the three dryers 3, 6, and 7. The horizontal belt conveyor 9 includes a suspension frame and a hanging frame (both of which are attached to a third
It is suspended from the running rail 8 via a rail (not shown in the figure), so that it can move in the directions of arrows F and G within the passage E'. Opposed to the dryers 6 and 7, dryers 10 and 11 are arranged side by side across a passage E' with their respective input ports facing the passage E'.

The fourth horizontal belt conveyor 9 is viewed in the X direction.
FIG. 5 shows a view seen in the Y direction, and the following description will be made with reference to both sides. The elevated running rail 8 is a dryer 3
Carriage rollers 8a, 8a, 8a, which suspend suspension frame 13 with hollow prismatic rails supported by brackets 12 fixed to
It is adapted to be held and transferred on the rail surface 8b. The suspension frame 13 is a rectangular frame constructed by one upper beam 13a, one lower beam 13b, and two columns 13c, 13c made of steel with a U-shaped cross section that is concave toward the inside. It is.

A traverse drive unit 15 is provided at one end of the upper beam 13a, and the l-rail surface of the running rail 8 is held between an even number of friction tires 14, 14 driven by a pole-change type running motor with a brake (not shown). hand,
The suspended frame 13 can be elevated and moved along the rail 8. A guide loaf 13d is supported on the lower end of the suspension frame 13, and this guide roller is guided by the lower guide rail 18 and overlays,
The hanging lotus frame 13 is kept in a vertical position.
The lower guide rail 18 described above is installed on the side of the passage and spaced apart from the ground surface. In this embodiment, the lower guide rail 18 is fixedly supported on the side wall of the dryer 3,677. As a result, when installing the lower guide rail 18, there is no dust that may interfere with surface obstacles such as piping, and the lower guide rail 18 does not interfere with installing piping or the like on the earth's surface. Two pillars 16a, 16a are slidably joined to the pillars 13c, 13c having a U-shaped cross section, and a beam 16b horizontally connects the upper ends of these two pillars. The formed suspension frame 16 is suspended from the upper beam 13a of the suspension frame 13 by an electric winch 17.

A conveyor stand 9a of the horizontal belt conveyor 9 is fixed at right angles to this hanging frame 16'. 16c is a reinforcing material.

In this way, the belt conveyor 9 has its frame ga supported horizontally on the hanging frame 16, and is raised and lowered by the electric winch 17. Reference numeral 16d denotes a guide roller that is pivoted on the upper end of the pillar 16a of the suspension frame 16 and moves within the pillar 13c having a U-shaped cross section.

A guide plate (not shown) made of synthetic resin is attached to the lower end of the pillar 16a, so that it can smoothly slide over the inner surface of the branch 13c having a U-shaped cross section. The compare belt 9b of the horizontal belt conveyor 9 is driven in both forward and reverse directions by a conveyor drive motor 9c. gb is a guide plate on both sides of the conveyor. The three driving motors described above, namely the travel motor provided in the traverse drive unit 15, the electric winch 17, and the conveyor drive motor 9c, are operated by an automatic control device (not shown).

To convey linen using this device, the horizontal conveyor 9 is moved to the outlet of the dehydrator 1 as shown by the imaginary line in FIG.
Lower the linen to a position lined up with a, move the conveyor to the right, receive the linen 2 pushed out from the dehydrator 1, transfer it to the center of the horizontal conveyor 9, and dry it using the electric winch 17 on the horizontal conveyor 9 as shown by the solid line. Lift it up to the height of the input port 3b of the machine 3.

When conveying the linen 2 to the dryer 3, the compare belt 9b is subsequently moved to the right to feed the linen to the dryer 3.

In this way, the conveyor 9 is sent out from the dehydrator or receives the nen while horizontally transferring it, and then is lifted upward and placed directly opposite the input port of the dryer, so the length L of this conveyor 9 is Regardless of the height of the outlet of the dehydrator and the input port of the dryer, the length can be set to the extent that the linen 2 can be accommodated.

Therefore, it is possible to make the length of the oblique belt conveyor in the follow-up technology considerably shorter, and as a result, the width of the path required for this horizontal belt conveyor to pass can be narrowed. When receiving the nen 2 from the dehydrator 1 or transporting it to a dryer other than the dryer 3, the suspended frame 13
is run along the running rail 8 and stopped in front of a desired dryer.

Then, by moving the compare belt 9b to the right to send the linen to dryer 6 or 7, and to the left to send it to dryer 10 or 11, the linen can be sent to either dryer. can be transported. In the above-mentioned operation, when the suspension frame 13 travels along the running rail, it moves without touching the ground surface, so even if an object shorter than the minimum ground clearance M of the suspension frame is placed on the path, the suspension frame 13 will not touch the ground. Do not interfere with running.

Further, there is no hindrance to providing fixed equipment such as piping and wiring along the passage surface. Next, other embodiments of the present invention will be described with reference to FIGS. 6, 7, and 8, respectively.

In the embodiment shown in FIG. 6, two horizontal belt conveyors 9, 9 are arranged in upper and lower stages for one hanging frame 16'.
The respective conveyor drive motors 9c, 9c are designed to operate independently of each other.

In this embodiment, the linen can be loaded onto two horizontal belt conveyors and run along the running rails, thereby substantially shortening the time required for running and increasing efficiency. However, of the two horizontal belt conveyors 9, 9, when the upper horizontal belt conveyor is lowered to the outlet of the dehydrator to receive linen, the lower horizontal belt conveyor must descend further down. . Furthermore, when the lower horizontal belt conveyor is raised to the input port of the dryer to feed linen, the upper horizontal belt conveyor must rise above it. For these reasons, the suspension frame 13' in the embodiment of FIG. 6 is different from the suspension frame 1 in the embodiment (FIG. 5).
It has to be made longer in the vertical direction compared to 3. Accordingly, the minimum ground clearance M' in the embodiment of FIG.
Although it is smaller than the minimum ground clearance M in the embodiment shown in the figure, this minimum ground clearance M' is sufficiently effective in practice to avoid interference with ground obstacles (pipes, etc.). In the embodiment shown in FIG. 7, two horizontal belt conveyors 9
, 9' are arranged in parallel at the same height, and accordingly, the suspension frame 13★ and the suspension frame 16'' are also made wide.

This embodiment has the same advantage as the embodiment shown in FIG. 6 above, in that it can run with one linen on each of the two horizontal belt conveyors 9 and 9'. The minimum ground clearance M dimension of the suspension frame can be increased substantially in the same manner as in the embodiment of FIG. FIG. 8 is a plan view of an embodiment different from the above.

A dehydrator facing aisle E'' and seven dryers 3, 6,
7, 10, 11, 19 and 20 are arranged side by side, and an elevated traveling rail 8' is provided above the center of this passage E''. 8'c and 8'd are pillars at both ends. .

The running rail is supported at two intermediate points by rail support beams 8'e and 6'c that span the tops of two dryers facing each other across a passage. In this embodiment, two horizontal belt conveyors 9, 9 are arranged side by side at the same height as in the embodiment shown in FIG. 7 described above.
In this embodiment, unlike each of the previously described embodiments, the horizontal belt conveyors 9, 9
The center portion of the conveyor stand 9a is fixed. In this embodiment, since the horizontal belt conveyors 9, 9 are supported near their centers of gravity, the force required to support them in a horizontal position is small. Therefore, since the force applied to the suspension frame 21 and the suspension frame 22 is small, the weight of these members can be reduced. As detailed above, the shuttle conveyor for dewatering and drying equipment of the present invention includes an elevated traveling rail provided on a passageway facing the outlet of a dehydrator and the input ports of a plurality of dryers; A self-propelled suspension frame suspended on the above-mentioned traveling rail, a horizontal belt conveyor that can be driven up and down by the above-mentioned suspension frame and capable of forward and reverse rotation, and installed at a distance from the ground on the side of the above-mentioned long route. By providing a running guide rail for the suspended frame and configuring the suspended frame to run without interfering with obstacles on the ground, the width dimension of the passage area of the counterfeit conveyor equipment can be significantly reduced. This means that even if fixed equipment is constructed or objects are placed on the ground within the passageway, it will not impede transport, and it will also be able to accommodate multiple dryers installed side by side on both sides of the passageway. You can send linen.
