[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for cleaning objects to be cleaned such as coins and game medals,
More specifically, a transport that lifts and transports an object to be cleaned on the inner peripheral surface of a cleaning drum that is rotatable around a horizontal axis having a supply port and a discharge port for the object to be cleaned with the driving rotation of the cleaning drum. A cleaning apparatus having a discharge chute that forms a projection and receives an object to be cleaned that is lifted by the transport projection and then drops through the discharge port of the cleaning drum, and that slides and discharges the object to be cleaned to the outside. About.

[0002]

2. Description of the Related Art In a conventional cleaning apparatus, each gap between opposite side edges of a discharge chute in the width direction of rotation and the conveying projection is defined as a gap smaller than the size of an object to be cleaned. And the projecting length in the rotation radial direction of the transport projection is configured to be greater than the size of the object to be cleaned, and further, the sliding guide surface of the discharge chute is formed in an uneven plane. (See, for example, JP-A-6-315568 and JP-A-6-81587).

[0003]

In the case of the conventional cleaning apparatus, when a large number of objects to be cleaned supplied from the supply port into the cleaning drum are lifted by the transfer projections, the objects to be cleaned are moved to the tip of the transfer projections. In particular, when the object to be cleaned rises and is inclined to protrude toward the center of rotation from the movement trajectory of the tip of the transport projection, the object to be cleaned is formed between the tip of the transport projection and the discharge chute. There is a possibility that it may bite in a state of tension between one side edge part facing the lifting path side, and if such biting occurs, not only will the object to be cleaned be deformed, but also the deformation of the discharge chute itself and its There is a problem that the mounting portion is damaged.

[0004] The present invention has been made in view of the above-mentioned circumstances, and its main problem is that the transfer is carried out by a rational modification between the transfer protrusion of the cleaning drum and the side edge portion of the discharge chute. It is an object of the present invention to provide a cleaning apparatus capable of transferring the object to be cleaned lifted and conveyed by the projection to the discharge chute without biting, regardless of the posture.

[0005]

According to a first aspect of the present invention, there is provided a cleaning apparatus according to the first aspect of the present invention, which is configured to lift the discharge chute out of both side edges in the width direction of the discharge chute. The point that a gap substantially equal to or larger than the size of one object to be cleaned is formed between the one side edge portion facing the path side and the transport projection in the rotational radius direction. According to the above-mentioned characteristic configuration, when a large number of objects to be cleaned supplied into the cleaning drum are lifted by the transport projection, the object to be cleaned rises at the tip of the transport projection, and rotates more than the tip movement locus of the transport projection. Even if it projects to the center side, a gap is formed between the transport projection and one side edge portion on the side of the lifting chute of the discharge chute, which is substantially the same as or larger than the size of one object to be cleaned. Therefore, the rising upper end of the object to be cleaned does not collide with one side edge of the discharge chute, or bite into the one side edge of the discharge chute. Therefore, the simple and economical remodeling of the gap between the conveyed projections of the cleaning drum and the one side edge portion of the discharge chute in the rotational radial direction as described above is simple and economical. The object to be cleaned, which has been washed in the cleaning drum, can be reliably transferred onto the sliding guide surface of the discharge chute while suppressing the deformation and breakage of the object to be cleaned and the discharge chute caused by the bite.

According to a second aspect of the present invention, there is provided a cleaning apparatus, wherein one cleaning object is provided between the other side edge portions of the discharge chute in the width direction and the conveyance projection in the rotational radius direction. The point is that a gap that is substantially the same as or larger than the size is formed. According to the characteristic configuration, when the object to be washed that is dropped after being lifted by the transport projection of the washing drum is received by the discharge chute, the received object to be washed rises at the other side edge portion of the discharge chute, and Even if it protrudes radially outward from the other side edge portion, there is a gap between the other side edge portion of the discharge chute and the transport projection that is substantially the same as or larger than the size of one cleaning object. Since it is formed, the upper end of the object to be cleaned does not collide with the tip of the transport projection that rotates integrally with the cleaning drum, or does not bite in a state of being stretched between the tip of the transport projection and the transport projection. . Therefore, the object to be cleaned washed in the cleaning drum is reliably and smoothly placed on the sliding guide surface of the discharge chute while suppressing deformation and breakage of the object to be cleaned and the discharge chute caused by the bite of the object to be cleaned. Can be delivered.

A feature of the cleaning apparatus according to the third aspect of the present invention is that the slide-down guide surface of the discharge chute is curved so as to be located lower toward the center in the width direction. According to the above-mentioned characteristic configuration, even if an object to be washed which is lifted by the transport projection of the washing drum and then falls is received near the side edge portion of the sliding guide surface of the discharge chute, the object to be washed is slid down. Sliding guidance can be performed while approaching the center in the width direction of the surface, and falling off of the object to be cleaned during the sliding guidance can be suppressed. In addition, since the discharge chute is curved to increase the second moment of area, even if a large number of objects to be washed fall on the discharge chute, the amount of bending deformation of the discharge chute can be suppressed. Therefore, the object to be cleaned can always be smoothly guided downhill at the set inclination angle while improving the durability of the discharge chute.

A feature of the cleaning apparatus according to a fourth aspect of the present invention resides in that the other side edge portion in the width direction of the discharge chute is provided at a position higher than one side edge portion. According to the characteristic configuration, of the two side edges in the width direction of the discharge chute, one edge facing the lifting path side by the transport projection is low, and the other edge facing the return path of the transport projection is high. Therefore, during the movement along the lifting path, the object to be washed received by the sliding guide surface of the discharge chute is enlarged while expanding the receiving range of the object to be washed sliding obliquely downward from the transport protrusion. Dropping across the width direction can be suppressed.

The cleaning apparatus according to a fifth aspect of the present invention is characterized in that an endless rotating belt-like body is provided which conveys an object to be cleaned slid down and discharged from the discharge chute to a cleaning liquid removing means in a mounted state. The sliding chute made of synthetic resin is provided at the lower end of the discharge chute so as to be in sliding contact with the loading / transporting surface of the endless rotating strip. According to the above-mentioned characteristic configuration, the lower end side of the discharge chute is slid in contact with the mounting / transporting surface of the endless rotating belt-like body, and the object to be cleaned guided downhill along the slidedown guide surface of the discharge chute is moved. It is possible to suppress damage to the mounting and transporting surface of the endless rotating belt-like body while smoothly moving the mounting and transporting surface onto the mounting and transporting surface of the endless rotating belt-like body.

The cleaning apparatus according to a sixth aspect of the present invention is characterized in that a number of drain holes are formed in the endless rotating strip. According to the above-mentioned characteristic configuration, when the object to be cleaned, which has been subjected to the cleaning process by the cleaning drum, is transported and supplied to the cleaning liquid removing unit, a part of the cleaning liquid attached to the object to be cleaned is endlessly rotated. Can be discharged through a large number of drain holes, so that the operation of removing the adhered liquid from the object to be cleaned can be performed more reliably and more efficiently.
