Description

  The present invention relates to a container side cleaning device, and more particularly, to a cleaning device that removes liquid, powder, and the like adhering to and remaining on a side surface of a cosmetic container or the like and scrubbing the surface.

 In products such as cosmetics, after the composition is filled in a container, the composition may remain attached to the side surface. In addition, in order to remove the composition adhering to the side surface of the container, attempts have been made to perform liquid cleaning using water or the like (Patent Document 1). In this case, water droplets adhere to the container and remain. To do.

  In particular, the latter, such as liquid cleaning, has a high cleaning effect on the container, and water droplet removal is also eliminated by air blow, but it is effective even for fine water droplets on the top surface of the container and water droplets in the indentation on the side of the container. The problem that it could not be removed remained.

  As a method for eliminating such residual water droplets, evaporative drying is generally performed in a hot air drying furnace or the like. However, since the equipment becomes large and heat is applied to the product, usable products are limited. There is a problem that it ends up.

  Even when the drying process is performed, if water droplets are removed in advance, drying can be performed with a simple hot air tunnel or the like, and labor saving is expected.

JP 2003-285016 A

  Therefore, development of an apparatus for easily removing and cleaning the liquid and powder adhering to the side surface of the container is required, and an object of the present invention is to provide such an apparatus.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor sandwiched and rotated a container that is moving in a certain direction by two rotating bodies that rotate in the same direction, and this was rotated by another rotating body. It was found that the side surface of the container body can be efficiently cleaned by wiping, and the present invention has been completed.

  That is, the present invention relates to a planar conveyor for transporting containers, provided in a slight space on the conveyor surface, rotated in the same direction, and in a direction orthogonal to the moving direction of the planar conveyor. Side surface of container including two sandwiching vertical rotating bodies that move and sandwich the container, and a rubbing vertical rotating body that moves in contact with the container in conjunction with the movement of the sandwiching vertical rotating body and rubs around the container This is a cleaning device.

  In addition, the present invention transports the containers to be cleaned on a flat conveyor, and in the middle of the conveyance, provided with a small space on the conveyor surface, rotating in the same direction, and the moving direction of the conveyor. The container to be cleaned is sandwiched between two sandwiching vertical rotating bodies that move relative to each other in the orthogonal direction, and the container to be cleaned is caused by the rotational frictional force of the sandwiching vertical rotating body and the force in the conveying direction received from the conveyor surface. A rubbing vertical rotating body that moves to come into contact with the container in conjunction with the two sandwiched vertical rotating bodies while rotating by applying driving force, and cleans the side of the container to be cleaned by rubbing around the container. The container side surface cleaning method is characterized in that after a predetermined time elapses, the interval between the two sandwiching vertical rotators is opened and the container is conveyed again by a conveyor.

  ADVANTAGE OF THE INVENTION According to this invention, the to-be-removed thing adhering to side surfaces, such as a cosmetics container, can be removed efficiently. In particular, the target container becomes complicated, such as a square with rounded corners, and a dedicated machine is required, and even containers that have been cleaned manually by hand can be easily cleaned. .

  Hereinafter, the container side surface cleaning apparatus (hereinafter referred to as “cleaning apparatus”) according to the present invention will be described in more detail with reference to several drawings.

  FIG. 1 is a perspective view showing a preferred embodiment of the cleaning device of the present invention, and FIGS. 2 and 3 are views showing the movement of a container to be cleaned and each rotating body during cleaning. In the figure, 1 is a cleaning device, 2 is a conveyor, 3 is a sandwiching vertical rotating body, 4 is a rubbing vertical rotating body, 5 a container to be cleaned, 6 is a drive motor, 7 is a pulley, and 8 is a belt. Reference numeral 20 denotes a swing arm, 21 an air cylinder, 22 an arm tension spring, 23 a fulcrum, 24 a guide, 25 a frame, 26 a linear guide, 27 a moving frame, 28 a rack and pinion, 29 a moving A frame tension spring 30 is a rocking drive plate.

  As shown in FIG. 1, in the apparatus of the present invention, two moving frames 27a and 27b are installed on a linear guide 26 so as to freely move in a direction orthogonal to the conveying direction of the conveyor 2. The linear guide 26 is attached to a frame 25 fixed on the guide 24. In each moving frame 27a and 27b, sandwiched vertical rotators 3a and 3b are installed on the conveyor surface of the planar conveyor 2 in a state having a slight space (gap). This space is appropriately determined depending on the thickness of the container 5 to be cleaned, but is about 0.5 to 1 mm in the case of a normal cosmetic compact refill container. The sandwiched vertical rotator 3 has a flat cylindrical shape, and the thickness thereof may be approximately the same as the thickness of the container 5 to be cleaned.

  The sandwiched vertical rotator 3 is rotated in the same direction by a drive motor 6 via a pulley 7 and a belt 8. Then, one of the moving frames 27, 27 a, is moved along the linear guide 26 in a direction orthogonal to the conveying direction of the conveyor 2 by the force of the air cylinder 21. The moving force of the moving frame 27 a moves the other moving frame 27 b through the rack and pinion 28 in the opposite direction along the linear guide 26 by the same distance. Since the rack and pinion linear gears 28a and 28b are coupled by a moving frame tension spring 29, moderate elasticity is generated between the sandwiching vertical rotating bodies 3a and 3b, and flexible movement is achieved. Is possible.

  By the above mechanism, the two sandwiching vertical rotators 3a and 3b can be moved in the opposite direction in the direction orthogonal to the conveying direction of the conveyor 2 as a single unit on the left and right. This movement needs to be synchronized with the timing at which the container 5 to be cleaned is transported on the conveyor 2, and at the timing when the container 5 to be cleaned is just before the sandwiching vertical rotor 3, the sandwiching vertical rotor 3 is moved. The container 5 to be cleaned is sandwiched.

  FIG. 2 and FIG. 3 show the sandwiched state. As shown in FIG. 2, the container 5 to be cleaned is conveyed by the flat conveyor 2, but is in contact with and sandwiched between the two sandwiching vertical rotating bodies 3 a and 3 b, and at the same time, The rotational force is received by the frictional force and the force in the conveying direction received from the surface of the conveyor 2. Since the two sandwiched vertical rotators 3a and 3b sandwiched rotate in the counterclockwise direction, the container 5 to be cleaned begins to rotate in the clockwise direction.

  On the other hand, the rubbing vertical rotating body 4 is installed on the front side of the planar conveyor 2 in the conveying direction at a position that does not interfere with the conveyance of the container 5 to be cleaned, with a slight gap provided on the upper surface of the conveyor 2. The rubbing vertical rotating body 4 is attached to the tip of a swing arm 20 having a fulcrum 23 on the extension of the frame 25, and is provided at the tip of a moving frame 27b to which the sandwiching vertical rotating body 3b is attached. In conjunction with the movement of the swing drive plate 30, it moves toward the center of the planar conveyor 2. Since the swing arm 20 and the swing drive plate 30 are coupled to each other by the arm tension spring 22, the rubbing vertical rotating body 4 can freely rotate while having appropriate elasticity. it can. With such a mechanism, the rubbing vertical rotating body 4 can sandwich and clean the container 5 to be cleaned together with the two sandwiching vertical rotating bodies 3 while having a considerable degree of freedom.

  As described above, the two sandwiching vertical rotators 3a and 3b sandwich the container 5 to be cleaned, provide a rotational force to the container and clean the side of the container, but are not limited thereto. As shown in FIG. 4, one of the outer peripheral surfaces is formed of the friction material 9 and the lower portion is formed of the adsorbing material 10 (FIG. 4A). It is preferable that it is formed of the friction material 9 (FIG. 4B). A part of the substance to be removed can be removed by these adsorbing materials 10. The adsorbing material 10 is a suction sheet such as a flocking cloth, a continuous foam sponge, or a thick cloth, and rubber or the like is used as the friction material.

  Further, the rubbing vertical rotating body 4 is not limited to this, but is mainly a taper type as shown in FIG. 5 in order to scrape the container 5 to be cleaned and remove the remaining substance to be removed. It is preferable that the outer periphery is formed of a gas permeable foam material 11 such as urethane foam. With such a configuration, even if there is a dent on the side surface of the container body, it can be rubbed to the inside, and the remaining substance to be removed can be completely removed.

  In addition, the sandwiching vertical rotating body 3 and the scraping vertical rotating body 4 have a rotating shaft serving as a suction pipe 12, and continuously remove the objects to be removed from the inside of the shaft through the adsorbing material or foaming material on the contact surface. Since it is combined with a suction device (not shown) for eliminating suction, the object to be removed adsorbed on the material can be removed, and the next container 5 to be cleaned can be cleaned.

  Then, at the stage where the container 5 to be cleaned is rotated once or more, preferably two times, the interval between the sandwiched vertical rotators 3a and 3b is opened, and the container 5 to be cleaned is resumed by the conveyor.

  As a result, the side surface of the container 5 to be cleaned is cleaned. The container 5 to be cleaned may be a flat circular dish or a square dish with rounded corners. However, the effect is particularly great when applied to a square dish with a depression on the side.

  Prior to the above-described cleaning, a horizontal suction adsorption rotating cylinder parallel to the conveyor surface and perpendicular to the moving direction as shown in FIG. 6 is provided on the front side of the moving direction of the conveyor, and an object to be removed ( For example, minute water droplets) can be removed. As this horizontal suction adsorption rotating cylinder, a roll around a sheet-like adsorbent having moisture permeability can be used, and this roll is preferably combined with a suction device for sucking and removing an object to be removed. .

  The cleaning device of the present invention can reliably clean the side surface of not only a circular container but also a rectangular container with rounded corners. Moreover, since this apparatus does not require large-scale equipment, it is highly economical.

   Therefore, it can be advantageously used as an apparatus for cleaning the side surfaces of containers such as cosmetics.
