Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a cleaning device for cleaning pine mats placed and transported by a conveying device, and a cleaning solution contained in the mats cleaned by this cleaning device to the mats. The present invention relates to a cleaning treatment device for mats, which is equipped with a vacuum device that sucks suction from the upper surface side of the mat.

[Conventional technology]

In this type of mat cleaning treatment equipment, when the vacuum device sucks the cleaning liquid contained in the mats cleaned by the cleaning device from the top side of the mat being transported, the starting end of the mat is connected to the suction port of the vacuum device. The conveyance may stop due to suction and holding. In this state, when the conveying end portion of the pine is transferred by the conveying device, an inchworm phenomenon occurs in which the intermediate portion of the pine is raised, and the pine is brought into contact with the loading and conveying surface of the conveying device and the suction port of the vacuum device. You will end up getting stuck between.

For this reason, conventionally, the techniques shown in [1] and [2] below have been used.

[1] A drive mechanism for raising and lowering the suction tube of the vacuum device, and a sensor for detecting that the conveyance start end of the mat has passed through the suction port of the suction tube, and the drive mechanism is provided based on the detection signal of the sensor. A control device that controls the operation of the mechanism and the conveying device that conveys the mat, and controls the operation of the conveying device so that the suction port moves from the center of the mat toward the front and rear ends of the mat.

[2] Between the suction port of the suction tube constituting the vacuum device and the mat mounting and conveying surface of the conveying device, a plurality of conveying bodies that clamp and convey the mat in cooperation with the conveying device are installed in the mat conveying width direction. placed side by side at specified intervals (for example,
-Refer to Publication No. 4677).

[The problem that the idea attempts to solve]

The conventional device described in [1] above includes a drive mechanism that raises the suction cylinder, a sensor that detects the starting end of the mat conveyance, and a control device that controls the operation of the drive mechanism and the conveyance device based on the detection signal of this sensor. Not only does the configuration become complicated as it requires a large number of parts such as In order to carry out the work process of suctioning the cleaning liquid, it is necessary to control the lifting and lowering of the suction tube and the drive of the conveyance device, respectively, and it takes a lot of time to remove the cleaning liquid.

Furthermore, the conventional device described in [2] above does not require a sensor for detecting the starting end of mat conveyance, nor does it require complicated drive control means for the suction cylinder or conveyance device, allowing the structure to be simplified and the working time to be shortened. Although this method is useful in that it can be implemented, it gives rise to the following new problems.

That is, since it is necessary to apply a necessary tension to the conveying body in order to suppress lifting of the mat, the cross-sectional area of the conveying body is required to be greater than a certain level.
However, if the carrier is made wide in plan view, the range of suction action by the suction tube will be narrowed, and conversely, if the conveyor is narrow in plan view, although the range of suction action can be widened, There was a problem in that the vertical thickness of the conveyor increased, creating a large gap between the mat surface and the suction port of the suction cylinder, resulting in a decrease in suction power.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning device for mats that can efficiently and quickly remove the cleaning liquid contained in the mats over a wide area of the mats while having a simple configuration.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a cleaning device that cleans the mats that have been placed and transported by a conveyance device, and a cleaning liquid contained in the mats that has been cleaned by this cleaning device that is sucked from the top side of the mats. In a pine cleaning treatment device that is provided with a vacuum device for cleaning mats, a mat cleaning device is provided between the suction port of the suction cylinder constituting the vacuum device and the mat mounting and conveying surface of the conveying device in cooperation with the conveying device. A plurality of conveying bodies for pinching and conveying are arranged in parallel at predetermined intervals in the mat conveying width direction, and the conveying bodies are configured in the form of a narrow string, and at the mouth edge of the suction port of the suction cylinder , a recessed portion is formed that allows the upper half of the string-like conveying body to move in the conveying direction in a recessed state.

A cleaning brush for cleaning the back side of the mat after being cleaned and a water supply device for supplying water to the cleaning brush are disposed on the downstream side of the vacuum device disposed at the transportation end of the transportation device. It is recommended to set

Further, the cleaning device and the vacuum device may be arranged in pairs along the mat conveyance direction.

[Effect]

a While preventing the pine transported by the plurality of transport bodies provided as above from being suctioned and held by the suction port of the suction cylinder, the pine is not adversely affected by the suction force of the suction cylinder. The cleaning liquid contained in the mat can be removed by suction by moving the mat reliably and smoothly with respect to the suction port of the suction cylinder.

(b) Furthermore, by arranging the plurality of conveyance bodies in parallel at predetermined intervals in the mat conveyance width direction, and each conveyance body being in the form of a narrow string, it is possible to Since the cleaning liquid contained in the mat can be diverted from the lateral side of the transport body and sucked up from between adjacent transport bodies using the suction cylinder, the cleaning liquid contained in the mat can be absorbed from the part of the mat where the transport body is located. Cleaning liquid can also be reliably removed by suction.

c In addition, even if the thickness of the conveyor increases due to the narrow width of the conveyor, the thickness of the string can be absorbed by the recess formed in the suction port of the suction cylinder, so that the area where the conveyor is present can be The formation of a large gap between the surface of the mat and the suction port can be avoided.

(d) Furthermore, when the cleaning brush and water supply device are provided, the back surface of the mat after being cleaned is washed with water by the cleaning brush and the water supply device.

[Effect of idea]

Because of the above-mentioned action, the cleaning liquid can be reliably suctioned and removed using a plurality of conveyors while suppressing the lifting of the mat due to the suction action of the suction cylinder. And compared to the structure using a control device etc.
It is possible to simplify the configuration and improve work efficiency by eliminating the need for many parts and unnecessary operations, and also allows the rim of the suction port to be placed on the mat surface without being affected by the thickness of the string. Since it can be brought close enough, a sufficiently large suction force can be applied to a wide area of the mat surface, allowing for even more efficient work.

Furthermore, by installing the cleaning brush and the water supply device that supplies water to it as described above, it is possible to reliably clean the back side of the mat, further improving the degree of cleaning of the mat. can be achieved.
