Abstract

PURPOSE: To adequately rub the whole surface of a label stuck on a cylindrical part by arranging rubbing mechanism in such a manner that a generating line which generates a curved surface formed by the rotation of a brush is nearly in the transportation direction. CONSTITUTION: A brush 5 is rubbed along the outer ruled line of a generating line Z direction view which is made by at least parts on which labels L1, L2 are stuck of a SAKE bottle B by installing a block 32 for a detour and a block 34 for backup. The bottle B which reached the entrance part of a belt transmission mechanism 8 by the drive of a chain conveyer C is sandwiched between a coupling type V belt 47 and the brush 5 and sent out while rotating clockwise on a plane view forward in the transportation direction Y by the rotation of the belt 47. A rubbing mechanism 6 rubs the brush 5 on the labels L1, L2 downward from above. Since the bottle B turns around a central shaft X, the brush 5 is rubbed on the whole surface of the bottle B.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush rubbing device for a label attached to a cylindrical container, which facilitates removal of a label attached to a cylindrical portion of a glass bottle or a cup-shaped glass container.

[0002]

2. Description of the Related Art Conventionally, as a technique for removing a label attached to a container, the container itself is immersed in a cleaning solution such as caustic soda to soften the label itself and the adhesive, and then the label is applied by using a high pressure stream or the like. What peels off is known.
However, in recent years, more and more labels of this type have a surface coated with a resin. And since it is extremely difficult for the cleaning solution to penetrate, it is necessary to make improvements such as lengthening the immersion part in the peeling line and using a cleaning solution with a high peeling ability. However, there has been a problem that it becomes difficult to recycle the container due to the increase in the cost for recycling the container. Therefore, in order to allow the cleaning solution to penetrate the label in a short time, it has been desired to introduce a brush rubbing device that can sufficiently scratch the entire label and can be manufactured at low cost.

On the other hand, as a prior art relating to dry label removal, for example, as described in JP-A-5-4079,
It is known that a rotating brush having a rotation axis oriented in parallel with the rotating mechanism is rubbed on the side surfaces of the bottle supported by the bottle pressing / supporting rotating mechanism facing each other in the vertical direction.
However, in the prior art, in order to rub the rotating brush as long as possible during the transportation of the bottle, both the bottle pressing / supporting rotating mechanism and the rotating brush are supported on the rotatable support frame as a whole. However, there is a problem that the structure of the device is complicated and expensive. Also, since the bottle and the rotating brush rotate about axes that are parallel to each other, if deterioration occurs at a part of the position of the rotating brush in the rotation axis direction, it becomes difficult to immediately remove the label on that part, and this rotation Since it is necessary to provide a plurality of brushes in order to improve the processing efficiency of the apparatus, it is always necessary to perform maintenance work for complicated rotary brushes.

[0004]

In view of such a problem,
INDUSTRIAL APPLICABILITY The present invention is capable of manufacturing a simple structure at low cost, but at least it is possible to sufficiently scratch the entire surface of the label attached to the cylindrical portion, and moreover, the cylindrical container is attached so that the brush can be easily maintained. It is an object to provide a brush rubbing device for a label.

[0005]

In order to achieve the above-mentioned object, the first characteristic constitution of the present invention is that the container having a label attached to at least the cylindrical portion is rotated while rotating around the central axis of the cylindrical portion. A rotary transport mechanism for transporting in a transport direction intersecting the central axis, and a rubbing mechanism for rubbing a rotating brush on the label of the container rotated by the rotary transport mechanism to scratch the label, The rubbing mechanism is arranged so that the generatrix forming the curved surface formed by the rotation of the above is substantially parallel to the carrying direction.

A second characteristic configuration of the present invention is, in addition to the first characteristic configuration described above, that the rotary transport mechanism sandwiches the container between a part of the winding medium node and the brush. A winding transmission mechanism that rotates the sandwiched container by rolling by moving a part of the container substantially parallel to the busbar, and an intermittent supply mechanism that intermittently supplies the container to the winding transmission mechanism are provided. Especially.

A third characteristic constitution of the present invention is, in addition to the first or second characteristic constitution, the brush comprises a plurality of brush units in which thin wires are implanted in an elongated rigid member. An attaching mechanism attaches these brush units to a winding medium node of another winding transmission mechanism with its longitudinal direction oriented in the direction of the busbar, and at least the busbar formed by at least the labeled portion of the container. The brush is rubbed along the outline of the direction.

[0008]

According to the first characteristic structure, the rotary transport mechanism transports the container in the direction intersecting with the central axis of the cylindrical portion while rotating the same about the central axis of the cylindrical portion, and is formed by the rotation of the brush in the rubbing mechanism. Since the generatrix forming the curved surface is substantially parallel to the conveying direction, the generatrix and the central axis of the container have a twisted relationship. At a certain moment, the label is rubbed by the brush along the central axis direction, and the container rotates around the central axis. As a result, the entire surface of the label is scratched by the brush. Since the brush is constantly rubbed against the conveyed container, the label is efficiently scratched. Moreover, since the entire surface of the brush contributes to scratching due to rubbing, and the relationship of the sliding contact position between the container and the brush is random, abrasion at a specific position is unlikely to occur, and brush maintenance is simplified.

Further, according to the second characteristic construction, the main part of the rotary transport mechanism can be constructed with a simple construction in which the winding transmission mechanism is provided and the container is rolled. Moreover, by providing the intermittent supply mechanism, it is possible to prevent damage to the containers themselves due to contact between the containers.

Further, according to the third characteristic configuration, the brush unit is attached to the other winding transmission mechanism, and at least the portion of the container to which the label is attached is formed along the outline of the direction of the generatrix line. By wrapping the brush so that the brush is rubbed, the brush can be sufficiently rubbed against a cylinder that is long with respect to the central axis direction, the shoulder portion of the bottle, and the like.

[0011]

As described above, according to the first characteristic structure of the brush rubbing device for the label stuck to the cylindrical container according to the present invention, the brush can be constantly rubbed against the entire surface of the label stuck to the cylindrical portion. It has become possible to provide a simple and low-cost device which has high processing capacity and can be installed without dividing and modifying an existing line without further rotating a rotating rubbing mechanism with respect to a machine base. Moreover, deterioration of a specific position of the brush is unlikely to occur, which facilitates maintenance.
As a result, it is possible to easily remove the label in the post-process and the like, and it is possible to reduce the cost for recycling the container and promote the recycling of the container.

Further, according to the second characteristic constitution of the present invention, the rotary conveyance mechanism can be constructed more simply and at low cost, and according to the third characteristic constitution of the present invention,
Labels attached to a wide range in the direction of the central axis and labels attached to the shoulders of bottles can now be sufficiently scratched, and this type of label can be easily removed.
