DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet washing machine for washing a sheet pallet.

[0002]

Conventionally, when carrying out cargo handling work using a forklift, or when storing or transporting various materials and products, the thickness of the object is effectively increased. A sheet pallet made of a synthetic resin having a flexibility of about 2 mm and having high flexibility is often used. In such a sheet pallet, it is necessary to clean the sheet pallet because the pallet adheres to the mud and oil during use and becomes dirty. Then, a sheet washing machine has been proposed in order to reduce the washing work of manually washing the sheets one by one using a deck brush or the like and draining the sheets one by one.

FIG. 5 shows the basic structure of the conventional sheet washer 1, in which a pull-in roll 2, a sheet guide 3, and a squeezing roll 4 are arranged from the front side of a sheet pallet transfer path. The cleaning brush 5 is arranged at the upper part and the lower part. The draw-in rolls 2 are a pair of upper and lower rolls, and rotate in a direction in which the sheet pallets are fed in contact with each other, and feed the sheet pallets inserted between the rolls toward the next sheet guide 3. Things. Seed guide 3
As shown in FIG. 6, a plurality of wires 7 such as metal wires extending in the sheet feeding direction are arranged at predetermined intervals in a direction orthogonal to the sheet feeding direction. The wires 7 are arranged and connected to a connecting rod 8 made of a metal wire or the like passed in a direction orthogonal to the wires 7. The connecting rods 8 are connected at two positions, for example, a front side and a rear side with respect to the intersection 9 with the cleaning brush 5. The cleaning brushes 5 are each in the form of a roll, and each of the cleaning brushes 5 comes into contact with a sheet pallet passing through the sheet feeding gap 6 by rotating. The cleaning liquid is sprayed by cleaning liquid supply means (not shown), and the cleaning brush 5 contacts the front and back surfaces of the sheet pallet in a state of being wet with the cleaning liquid, thereby cleaning the sheet pallet. The squeezing roll 4 located on the sheet feeding side of the sheet guide 3 is formed by winding a water-absorbing material around the outer circumference. As shown in FIG. The sheet pallet sent out from the pallet passes therethrough to remove the attached cleaning liquid. And
In the sheet washer 1 having the above-described configuration, a required portion is slightly bent so that the intersection 9 of the sheet guide 3 with the cleaning brush 5 is located at a lower position, and the sheet guide 3 is guided by the sheet guide and located at the intersection 9. The sheet pallet is slightly curved, and the cleaning liquid is stored on the sheet pallet to improve the cleaning effect.

However, since each of the sheet guides through which the sheet pallets pass is provided with a connecting rod orthogonal to the sheet feeding direction, when a deformed sheet pallet or a partially cut and raised sheet pallet with a tear is sent out. However, there has been a problem that the deformed portion or the cut-and-raised portion of the sheet pallet enters between the wire rods and is caught by the connecting rod, thereby causing clogging. In view of the above circumstances, it is an object of the present invention to forcibly guide the above-mentioned deformed portion or cut-and-raised portion which is likely to enter between wire rods of a sheet guide into a sheet feeding gap, and to eliminate clogging of a sheet pallet. And

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a draw roll for feeding a sheet pallet in one direction and a sheet feed gap on the sheet feed side of the draw roll. A pair of sheet guides, a cleaning brush for cleaning the sheet pallet under the supply of the cleaning liquid, and a squeezing roll for removing the cleaning liquid from the sheet pallet located on the sheet feeding side of the sheet guide. The sheet guide is configured such that a plurality of wires each extending in the sheet feeding direction are arranged at a predetermined interval in a direction orthogonal to the sheet feeding direction, and the sheet guide is positioned in a direction orthogonal to the sheet feeding direction. A sheet washer comprising a plurality of wires connected to a connecting plate for guiding a sheet pallet to a side. Provided, it is intended to solve the above problems. In the present invention, the connecting plate located at an upper position with respect to the sheet feeding gap is inclined in a direction to open upward toward the drawing roll, and the connecting plate positioned at a lower position with respect to the sheet feeding gap is located at the drawing rule side. It is preferable that it is inclined in a direction to open downward toward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the embodiments shown in FIGS. 5 and 6 are denoted by the same reference numerals, and description thereof is omitted. As shown in FIG. 1, the sheet guide 3 of the sheet washer 1 includes a plate-shaped connecting plate 10 extending in a direction orthogonal to the sheet feeding direction, and the wires 7 are connected to the connecting plate 10. ing. The connecting plate 10 is arranged on the upper side of the wire 7 in the upper sheet guide 3 and is arranged on the lower side of the wire 7 in the lower sheet guide 3. The front end 11 of the drawing roll 10 on the side of the drawing roll 2 is provided with an inclined portion 12 inclined away from the wire 7 so as to be away from the wire 7. Further, reference numeral 13 denotes a rod-shaped reinforcing member which is attached over the bent portion of the connecting plate 10 to reinforce the connecting plate 10. The reinforcing member plays a role to further enhance the strength of the connecting plate, and is not always required if the connecting plate itself has sufficient strength.

[0007] Of the connecting plates 10 supporting the wire 7 as described above, the connecting plate 1 positioned higher than the sheet feeding gap 6.
Reference numeral 0 denotes an inclined angle that rises with respect to the wire 7 and includes an inclined portion 12 that is inclined in a direction that opens toward the pulling roll, and the other connection that is located below the sheet feeding gap 6. Since the plate 10 also has the inclined portion 12 which is inclined downwardly with respect to the wire 7 and is inclined in a direction to open toward the pulling roll side, the plate 10 is temporarily moved from the pulling roll 2 to the sheet guide 3 side. Even if a part of the sheet pallet sent out enters between the wire rods 7, the sheet pallet is forcibly fed in contact with the inclined portion 12 of the preceding connecting plate 10 in the process of moving. The sheet pallet is guided to the inside of the gap 6, and the sheet pallet moves properly without causing a jam. In the sheet pallet that has passed through the front connecting plate 10, a part of the sheet pallet may enter the wire 7 again, but when it reaches the rear connecting plate 10, the connecting plate 10 The sheet is forcibly guided into the sheet feeding gap 6 by the inclined portion 12 so that the sheet is fed toward the squeezing roll 4 without causing clogging.

In FIG. 1, reference numeral 14 denotes a fixing plate attached to the leading end of each of the wires 7 in the upper and lower seed guides 3 in the width direction of the sheet guide (a direction orthogonal to the sheet feeding direction). The front end of the wire is supported so that the front end of the wire does not move due to an impact or the like when the fed sheet pallet contacts the sheet guide. Also, as shown in FIG. 3, the wire rods 7 in the upper and lower sheet guides.
Are dense on both sides in the width direction, so that the movement of the side of the sheet pallet, which is likely to be turned up when passing between the sheet guides, is suppressed by the densely arranged wires. . FIG. 3 shows a half of the sheet guide 3 in the width direction as viewed from above, and the other half (not shown) has the same structure.

[0009]

As described above, according to the sheet washer of the present invention, the draw-in roll for feeding the sheet pallet in one direction and the sheet feed gap are positioned on the sheet feed side of the draw-in roll. A pair of sheet guides, a cleaning brush for cleaning a sheet pallet under a supply of a cleaning liquid, and a squeezing roll for removing a cleaning liquid from the sheet pallet located on a sheet sending side of the sheet guide; The sheet guide arranges a plurality of wires each extending in the sheet feeding direction at a required interval in a direction orthogonal to the sheet feeding direction, and is located in a direction orthogonal to the sheet feeding direction and on the sheet feeding gap side. The plurality of wires are connected to a connecting plate for guiding a sheet pallet. As a result, even if a deformed sheet pallet or a sheet pallet having a part partially raised due to a tear is fed into the sheet feeding gap, the sheet pallet is deformed or raised by contact with the connecting plate, and the sheet is fed. Guided into the gap, the sheet pallet can be transported without causing clogging, so that not only a sheet pallet with an appropriate shape but also a sheet pallet with some deformation or cut can be washed. It has an effect that is excellent in practicality.
