Description

The present invention relates to an apparatus for removing burrs formed along the inner peripheral surface of an opening of a container filled with a powdered cosmetic, a solid powder cosmetic manufacturing apparatus equipped with this apparatus, and a method for removing burrs.

Generally, solid powder cosmetics such as foundations, eye shadows, and blushers are sold in a press-molded state and housed in packaging materials or the like. Specifically, the solid powder cosmetic is filled in a predetermined amount into a container having a concave portion called an inner tray, and is solidified into a substantially planar shape within the concave portion by being pressurized with a press or the like. .

At this time, in the press head of the press machine, the shape of the pressing surface is almost the same as the planar shape of the opening surface of the recess of the container, and the area of the pressing surface is slightly smaller than the area of the opening surface of the recess of the container. It is designed to. That is, the press head of the press is designed so that the end edge of the press head is located inside the inner circumferential surface of the opening while ensuring a predetermined clearance along the inner circumferential surface of the opening of the container.

The clearance is designed to make it easier to press the powdered cosmetic in the recess, and to allow the press head to be quickly and smoothly removed from the recess after pressing. Further, the clearance is provided to allow air mixed in the powder cosmetic before pressing to escape to the outside during pressing.

When pressing powdered cosmetics, oil removal paper, surface molding cloth, metal nets, etc. are placed between the press head and the powdered cosmetics. Due to this presence, burrs may be formed along the inner circumferential surface of the opening of the container, which are areas that are not sufficiently pressed. The burr easily falls off due to relatively weak vibrations, shocks, etc., and is scattered as residual powder.

The remaining powder adheres not only to the periphery of the container filled with the powdered cosmetic but also to the inside of the packaging material, resulting in poor appearance and low product value when displayed in stores. In addition, cosmetics such as foundation are often carried in pouches or bags, and even if no residual powder is observed when displayed at a store, when the user carries them around, they may Powder may scatter and contaminate the inside of your pouch or bag.

In order to solve the above problems, various studies have been made in the past. For example, Patent Document 1 describes an apparatus in which a container containing a solid powder cosmetic is transported by a pusher and air is blown onto the container transported to a fixed position to remove residual powder adhering to the container.
Further, for example, Patent Document 2 describes an apparatus for removing burrs using a compressed air injection mechanism.

However, the device described in Patent Document 1 is a device that only removes residual powder adhering to the outer surface of the container, and cannot remove burrs formed along the inner peripheral surface of the opening of the container. Furthermore, since the containers are transported intermittently using a pusher, there is a problem in that high processing efficiency cannot be obtained. Further, since the device described in Patent Document 2 is built into a filling machine that fills powdered cosmetics, it cannot be said that retrofitting the burr removal device itself is easy. In addition, there is little freedom in design changes and installation locations. As described above, the device described in Patent Document 2 has many problems in terms of equipment installation, and there is room for improvement in terms of simplifying the device.

[Compressed air supply source]
The compressed air supply source supplies compressed air to a first nozzle unit 40A and a second nozzle unit 40B (hereinafter, the two nozzle units may be simply referred to as "nozzle unit 40"), which will be described later. It is.
The compressed air supply source includes, for example, a compressed air supply device (not shown) such as a compressor or a compressed air tank, a compressed air control device 30 that controls the flow rate and pressure of compressed air from the compressed air supply device, and a compressed air control device 30 that controls the flow rate and pressure of compressed air from the compressed air supply device. It is composed of an air hose (not shown) that connects the supply device and the compressed air control device 30, and a piping tube 31 that connects the compressed air control device 30 and the nozzle unit 40.

In the burr removal device 1, the compressed air control device 30 is externally attached to a wall member 81a of a holding mechanism 80, which will be described later.

[First nozzle unit]
The first nozzle unit 40A is suspended and supported above the surface of the powdered cosmetic A filled and molded in the container 10, specifically by a holding mechanism 80, which will be described later, without contacting the conveying surface S. It is disposed above the level of the surface of the cosmetic A, and is disposed on the most upstream side with respect to the transport direction X.
The first nozzle unit 40A includes a first nozzle 411 and a second nozzle 412. The first nozzle 411 and the second nozzle 412 are arranged along the conveyance path R in order from the upstream side near the entrance of the conveyance path R with respect to the conveyance direction X.

The first nozzle unit 40A directs compressed air supplied from the compressed air control device 30 via the piping tube 31 toward the first side (long sides 10a, 10b) of the container 10 substantially parallel to the conveyance direction Then, the liquid is ejected in a direction substantially perpendicular to the transport direction X. That is, the first nozzle 411 blows out compressed air against the burr B formed on the longitudinal side surface 11a of the opening of the container 10 on the first side (long side 10a), and the second nozzle 412 blows out compressed air. , compressed air is ejected against the burr B formed on the longitudinal side surface 11b on the first side (long side 10b) side of the opening of the container 10.

The first nozzle 411 and the second nozzle 412 are both formed with the same configuration. Therefore, below, the first nozzle 411 will be explained as an example. In the second nozzle 412, components corresponding to the first nozzle 411 may be designated by the same reference numerals and a description thereof may be omitted.

The first nozzle 411 includes a nozzle body 42 made of, for example, resin, and a spout 43 provided at the tip of the nozzle body 42 (see FIG. 3).

The first nozzle 411 ejects compressed air from the ejection port 43 in a direction substantially perpendicular to the transport direction X. Here, the term "substantially orthogonal direction" refers to an angle of 45° to 135° with the transport direction X as an axis.
Since the jetting direction F of the compressed air jetted from the first nozzle 411 is substantially perpendicular to the conveyance direction X, the burr B formed on the inner peripheral surface of the opening of the container 10 is removed with a high probability. At the same time, even if the container 10 is lightweight, the placement position of the container 10 is prevented from being significantly displaced by the force of the ejected air.

The incident angle α of the compressed air jetted from the first nozzle 411 may be an acute angle, preferably 0° to 60°, more preferably 5° to 45°. Here, the incident angle α of the compressed air refers to the plane incident angle formed between the incident direction of the compressed air and the surface of the powder cosmetic A filled and molded in the container 10 (see FIG. 3).
Note that the incident angle α of the compressed air by the first nozzle 411 is determined by rotating the nozzle body 42 about the connecting member 84 and, if necessary, by rotating the first supporting member 83a of the holding mechanism 80, which will be described later. It can be adjusted by sliding the connecting member 85.
When the incident angle α of the compressed air is within the above range, the compressed air can be jetted against the inner circumferential surface of the opening of the container 10, and as a result, the burr B is removed with a high probability.

The first nozzle 411 and the second nozzle 412 are configured such that the direction F of compressed air from the first nozzle 411 and the direction F of the compressed air from the second nozzle 412 are opposite to each other. It is located.

It is preferable that the ejection port 43 of the first nozzle 411 ejects compressed air locally onto the inner peripheral surface of the opening of the container 10 . Note that locally spouting compressed air to the inner circumferential surface of the opening of the container 10 can be achieved by, for example, providing a plurality of small-diameter jet ports 43 in the first nozzle 411 and conveying the plural jet ports 43. This is achieved by arranging them in a line along the direction X. Note that the shape and size of the jet nozzle 43 are not limited, and examples of the shape include a round shape, a rectangular shape, and a flat shape.
By arranging a plurality of small-diameter jet ports 43 in a row, the jetted compressed air can obtain high directivity, and the jetted shape of the compressed air on the inner circumferential surface of the opening of the container 10 becomes band-like, and as a result, the powder Only the burrs formed on the inner peripheral surface of the opening can be removed without applying compressed air directly to the surface of the cosmetic A.

The number of ejection ports 43 of the first nozzle 411 is not limited. In addition, when providing a plurality of ejection ports, it is preferable to arrange them in a line along the conveyance direction X.

The amount of compressed air ejected from the ejection port 43 of the first nozzle 411 can be set as appropriate depending on the shape and size of the container 10 and the properties of the powder cosmetic A.
Further, in the burr removing apparatus 1, it is preferable that the compressed air ejected from the ejection port 43 of the first nozzle 411 is continuously supplied while the container 10 is being transported.

[Direction change member]
The direction changing member 50 is arranged downstream of the first nozzle unit 40A in the transport direction X.
The direction changing member 50 is a substantially rectangular flat plate made of metal such as stainless steel, and has a contact portion 51 a that contacts the outer surface of the container 10 .

In the burr removing device 1, the contact portion 51a is a substantially rectangular corner.
The form of the contact portion 51a is such that the contact portion 51a and the outer surface of the container 10 are brought into contact with each other by utilizing the movement of the container 10 by the transport mechanism 20, so that the mounting direction of the container 10 is changed to the first side (long side). As long as it can be changed so that the second side (short side) adjacent to the second side (short side) is substantially parallel to the transport direction X, it is possible to design it as appropriate.
In the burr removal device 1, the contact portion 51a is arranged to be in contact with the outer surface of the container 10 on the short side 10d side at a position approximately 20% to 50% of the short side 10d from the long side 10b side. It is preferable. If the contact position exceeds 50% of the short side 10d, the container 10 will not be properly converted and continuous transport will be hindered.

The direction changing member 50 is suspended and supported without contacting the conveying surface S by a holding mechanism 80 that will be described later.

The direction changing member 50 uses the movement of the container 10 by the transport mechanism 20 to bring the outer surface of the container 10 on the short side 10d into contact with the contact portion 51a, thereby changing the mounting direction of the container 10 into the first direction. It is converted so that the sides (long sides 10a, 10b) and the adjacent second sides (short sides 10c, 10d) are substantially parallel to the transport direction X. Specifically, the direction changing member 50 rotates the container 10 approximately 90 degrees in a horizontal plane about one side of the outer surface on the short side 10d side that is in contact with the contact portion 51a (container 10 (powder cosmetic A)). (rotated approximately 90 degrees) with the surface of the conveyance surface S in a parallel attitude.
Here, the expression that the second sides (short sides 10c, 10d) are substantially parallel to the transport direction X means that the inclination angle of the second sides (short sides 10c, 10d) with the transport direction This is the angle at which the burr B formed on the short side surfaces (11c, 11d) on the second sides (short sides 10c, 10d) subjected to the burr removal process in the section L2 can be removed. In the present invention, when the container is round, the second sides (short sides 10c, 10d) being substantially parallel to the transport direction X means that the tangent at the center point of the second arc is approximately parallel to the transport direction X. It means to be parallel.
Since the direction changing member 50 has a simple structure and configuration that does not include equipment such as a complicated drive device or electric equipment, a high degree of freedom in design changes and installation positions can be obtained.

The angle at which the direction of the container is changed by the direction changing member 50 may be determined as appropriate depending on the shape of the container 10, as long as the second side (short sides 10c, 10d) is turned approximately parallel to the conveying direction X. Configurable.
Here, the direction change angle of the container by the direction change member 50 refers to the angle (rotation angle) at which the container 10 rotates in a horizontal plane along the conveyance surface S, and specifically, The outer surface on the (short sides 10c, 10d) side is aligned with the direction of the second side (short sides 10c, 10d) before contacting the contact portion 51a, and the outer surface on the second side (short sides 10c, 10d) side. This refers to the angle that the side surface makes with the direction of the second side (short sides 10c, 10d) after contacting the contact portion 51a.

[Second nozzle unit]
The second nozzle unit 40B is suspended and supported above the surface of the powder cosmetic A filled and molded in the container 10, specifically by a holding mechanism 80 described later, without contacting the conveyance surface S, and the powder It is disposed above the level of the surface of the cosmetic A, and is disposed downstream of the direction changing member 50 in the transport direction X.
The second nozzle unit 40B includes a third nozzle 413 and a fourth nozzle 414. The third nozzle 413 and the fourth nozzle 414 are arranged along the conveyance path R in order from the upstream side near the direction changing member 50 with respect to the conveyance direction X. Further, the first nozzle 411, the second nozzle 412, the third nozzle 413, and the fourth nozzle 414 are connected to the conveyance path R in order from the upstream side near the entrance of the conveyance path R with respect to the conveyance direction X. A redirection member 50 is disposed along the nozzle and between the second and third nozzles.

The second nozzle unit 40B directs compressed air supplied from the compressed air control device 30 via the piping tube 31 toward the second side (short sides 10c, 10d) of the container 10 substantially parallel to the conveyance direction Then, the liquid is ejected in a direction substantially perpendicular to the transport direction X. That is, the third nozzle 413 blows compressed air against the burr B formed on the short side surface 11c on the second side (short side 10c) side of the opening of the container 10, and the fourth nozzle 414 The compressed air is ejected against the burr B formed on the short side surface 11d on the second side (short side 10d) of the opening of the container 10.

The third nozzle 413 and the fourth nozzle 414 are formed with the same configuration as the first nozzle 411 described above, so the description thereof will be omitted. In the third nozzle 413 and the fourth nozzle 414, components corresponding to the first nozzle 411 may be given the same reference numerals and the description thereof may be omitted.

The third nozzle 413 and the fourth nozzle 414 are configured such that the direction F of compressed air from the third nozzle 413 and the direction F of the compressed air from the fourth nozzle 414 are opposite to each other. It is located.

[Holding mechanism]
The burr removal device 1 is equipped with a holding mechanism 80 that holds the first nozzle unit 40A, the second nozzle unit 40B, and the direction changing member 50 together in a state where they do not come into contact with the conveying surface S. In the burr removal device 1, the compressed air control device 30 and piping tube 31 in the compressed air supply source, and the guide unit 70 are also held together by a holding mechanism 80.
Since the holding mechanism 80 holds the first nozzle unit 40A, the second nozzle unit 40B, and the direction changing member 50 together, the holding mechanism can be placed in a conveyance mechanism such as an existing belt conveyor, for example. Since the burr removing device can be constructed by simply doing the following, retrofitting of the burr removing device itself becomes easy, and flexibility in design changes and installation positions can be obtained.

The holding mechanism 80 includes a wall member 81a that extends along the conveyance path R and has a wall surface perpendicular to the conveyance surface S, and a stand member 81b that makes the wall member 81a independent.
In the holding mechanism 80, a stand member 81b is arranged substantially parallel to the transport direction X on one side of the outer peripheral edge of the frame 21 of the transport mechanism 20.

It further includes a first support member 86a that supports the first support member 86a, and a second support member 86b that supports the first support member 86a.

A plurality of first support members 83a and a plurality of second support members 83b that support the nozzle unit 40 are all formed with the same configuration. Therefore, below, one first support member 83a and one second support member 83b will be explained as an example (see FIG. 3).
