Description

[Detailed description of the invention] This invention applies conditioning oil to the bowling lane floor to clean dust, oil, etc. adhering to the lane floor in order to adjust and maintain the lane characteristics. The present invention relates to a cleaning mechanism for a bowling lane maintenance device.

The lane characteristics of bowling lanes are adjusted and maintained by applying a very thin layer of conditioning oil to the lane floor. For this reason, if dust, oil, etc. adhere to the lane floor surface, it will not be possible to adjust the desired lane characteristics. must be cleaned.

An example of a cleaning mechanism for a bowling lane maintenance device is shown in US Pat. No. 3,604,037. This device is equipped with an elongated fixed pad or weighted pad that spans the entire width of the lane in front of the oil application roller, and after the lane floor is cleaned with these pads, oil is applied by the oil application roller. There is.
Another example of a cleaning device is one in which a cleaning towel is brought into contact with the floor surface using a fixed rotating roller.

However, with such a cleaning mechanism, the fixed pad, weighted pad, or cleaning towel cannot maintain sufficient elastic contact with the lane floor surface, so the floor surface cannot be completely cleaned. In addition, the fixed pad, weighted pad, or cleaning towel are always pressed against the floor surface even when the conditioning oil application process is finished and the maintenance equipment is retracted, so the applied conditioner is There is a problem in that it tends to have an adverse effect on the dayning oil film. Furthermore, in the latter example, the towel on the rotating roller is moved so that the floor surface can be cleaned with a new towel surface, but this towel movement is continuously performed by the drive motor of the main body of the maintenance device. However, when cleaning is not performed, it is necessary to remove the rotating roller, which is a problem.

The purpose of the present invention is to solve the above-mentioned problems and to apply a towel or paper for cleaning the lane floor to the lane floor so as to maintain a uniform and constant contact pressure over the entire contact surface with the lane floor during cleaning. A bowling lane maintenance device that can press the towel or paper against the lane floor, release the towel or paper from the lane floor when not cleaning, and change the portion of the towel or paper that comes into contact with the lane floor independently of the operation of the maintenance device. The purpose of this invention is to provide a cleaning mechanism for cleaning.

This invention is a bowling lane maintenance device that adjusts and maintains bowling lanes.
A supply roller having a predetermined rotational resistance torque and containing a towel or paper used for cleaning the bowling lane floor; and a supply roller that contacts the lane floor with a constant pressure and separates the towel or paper from the lane floor as desired. an air cylinder mechanism that drives this roller; a take-up roller and its drive mechanism that intermittently winds up the towel or paper after cleaning; It is characterized by comprising a loosening mechanism that applies tension to the towel or paper.

The present invention will be explained in detail below with reference to the drawings.

FIG. 2 is a diagram showing the structure of an example of the cleaning mechanism of the bowling lane maintenance device according to the present invention, and FIG. 1 is a schematic enlarged view of the cleaning mechanism of FIG. 2. The bowling lane maintenance device 1 moves the bowling lane from the foul line to just before the pin zone using the running wheels 2 while cleaning the towel 4 of the cleaning mechanism 3.
The lane floor surface 5 is cleaned with a cleaning device, conditioning oil is applied with an oil application roller 6, and then a towel 4 and an oil application roller 6 are used to clean the lane floor surface 5.
The conditioner oil is removed from the lane floor surface, and the surface to which the conditioning oil is applied is finished by the buff roller 7 while retreating to the foul line again.

Side plates 8 parallel to the direction of movement of the main body 1 of the maintenance device are provided on both sides of the main body 1 of the maintenance device, and a towel 4 for cleaning the lane floor surface is provided between both sides of the plate.
form a route. That is, a towel supply roller 9 having a predetermined rotational resistance torque and containing a rolled towel is rotatably supported perpendicularly to the side plate 8 .
Further, a take-up roller 10 for winding up the towel after cleaning the lane floor surface is rotatably supported perpendicularly to the side plate 8. A pawl gear 11 is fixed to one end of a shaft 10a of a winding roller 10, and a plate member 12 is loosely fitted to the shaft of the winding roller 10. This plate-like member has a first
The pawl 12a is rotatably provided so that the tip of the pawl is always biased against the pawl gear 11, and a second pawl 13 is rotatably provided on the side plate 8, so that the tip of the pawl is always biased against the pawl gear 11. I'll do what I do. The main body side of the air cylinder 14 is rotatably supported by the side plate 8, and the piston end of the air cylinder 14 is supported by the plate member 1.
It is rotatably connected to the shaft 10a of No. 2 at a separate position.

A pressing roller 15 for pressing the towel 4 onto the lane floor is arranged between the towel supply roller 9 and the towel take-up roller 10. It is constructed so that it can move into contact with and separate from the lane floor surface as desired. That is, as shown in FIG. 3, a guide 17 is fixed inside the side plate 8 of the main body 1, a connecting rod 18 is slidably disposed in this guide, and a pressing roller is rotatable at the lower end of the connecting rod. At the same time, an air cylinder 19 is fixed to a side plate on the upper end side of the connecting rod, and its piston end is brought into contact with the upper surface of the connecting rod 18. Further, two flanges 18a are formed on the lower end side of the connecting rod 18, and a tension spring 20 is interposed between the upper end portion 17a of the guide 17 and the flange 18a to constantly bias the pressing roller 15 away from the lane floor surface. do.

The towel 4 is hung from a towel supply roller 9 to a take-up roller 10 along the outer surface of the pressing roller.

A towel loosening prevention mechanism 21 is provided between a pressing roller 15 and a take-up roller 10, so that the towel 4 has tension and is prevented from sagging regardless of the position of the pressing roller. That is, the arm 22 is rotatably supported on the side plate 8 of the main body 1, and the tip of the arm is biased toward the towel side by a torsion spring 23 interposed between the side plate 8 and the arm 22. A tension roller 22a is rotatably supported at the tip of the arm 22 over the entire length of the towel in the width direction, and applies tension to the towel.

The operation of the cleaning mechanism of the bowling lane maintenance device having such a configuration will be explained. The maintenance device main body 1 is mounted on the bowling lane and maintenance operation is started. The cleaning mechanism 3 operates the air cylinder 19 at a predetermined position on the bowling lane, causes the connecting rod 18 and the pressing roller 15 to protrude downward against the force of the spring 20, and moves the towel 4 on the pressing roller to the lane floor. Therefore, the pressing roller is brought into contact with the air cylinder 1.
It has a cushioning effect that can move up and down by a stroke of 9, and maintains a uniform and constant contact pressure over the entire contact surface in the longitudinal direction of the pressing roller 15 to elastically contact the lane floor surface 5. .

The portion of the towel in contact with the lane floor surface can be changed by operating the air cylinder 14 independently of the operation of the main body 1. When the air cylinder 14 is operated to retract its piston end, the plate member 12 rotates around the shaft 10a, and the first
The pawl 12a presses the pawl gear of the pawl gear 11 in accordance with the rotation of the plate member, thereby rotating the pawl gear and thus the take-up roller. Even if the piston end of the air cylinder 14 is then extended, the pawl gear 11 is locked by the second pawl 13 and does not move. Therefore, the air cylinder 14
The towel supply roller 9 is moved by the expansion and contraction of the piston end of the
The take-up roller can be rotated intermittently against rotational resistance.

After the main body 1 of the apparatus advances to the front of the pin zone of the bowling lane, the cleaning mechanism 3 releases the bias of the air cylinder 19 and raises the pressing roller 15 by the force of the spring 20. At this time, the length of the towel path tends to be shorter than the length of the towel between the towel supply roller 9 and the take-up roller, but the arm 22 rotates while pressing the roller 22a against the towel by the torsion spring 23. Therefore, the tension of the towel is maintained and the towel does not become loose at all times.

As is clear from the above description, according to the cleaning mechanism of the bowling lane maintenance device according to the present invention, (1) the towel or paper is placed between the towel or paper supply roller and its take-up roller used for cleaning the lane floor; A pressure roller that presses the lane floor against the lane floor surface is arranged, and an air cylinder that elastically presses this pressure roller is provided. The bowling lane cleaning towel or paper, which can be separated, contacts the lane floor surface sufficiently elastically with uniform and constant contact pressure to completely clean the bowling lane floor surface.

(2) A drive mechanism for the take-up roller that is independent of the main body of the maintenance device, a locking mechanism that applies tension to the towel regardless of the position of the pressing roller, and a tension spring that pulls the pressing roller upward are provided. Therefore, when cleaning is not performed, if the bias of the air cylinder 19 is released,
The pressing roller is separated from the lane floor surface, and the locking mechanism prevents the towel or paper from hanging down on the lane floor surface, and does not adversely affect the surface to which the conditioning oil is applied.

(3) The area where the towel or paper comes into contact with the lane floor can be freely changed by a drive mechanism independent of the main body of the maintenance device.
