Abstract

<P>PROBLEM TO BE SOLVED: To solve problems that aligning efficiency is unfavorable since only a part in the specific direction is selected from a part different in the mixedly existing direction and a part in the other direction is excluded from a process as a defective, and it is difficult to align a large part and a heavy part in the specific direction, in a conventional part aligning device. <P>SOLUTION: In the part supplied in a vertical attitude where a plate surface is substantially vertical to a horizontal plane, a surface state at right and left or one plate surface is detected by a surface detecting means, and the part is distributed according to the surface state of the plate surface by a part distributing means. The distributed part is made to pass through a part carrying passage having an attitude converting part for converting an attitude of its plate surface (for example, the vertical attitude is converted into a downward attitude), so that the distributed entire parts can be aligned by aligning one of the plate surfaces in the upward direction or the downward direction. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a component aligning apparatus for aligning with a cap opening downward to supply a cap to a capper that automatically attaches the cap to a stopper of a large container such as a 20-liter can made of polyethylene.

  Conventionally, when a cap is placed on a container such as a PET bottle for drinking water, the cap is usually placed in a state where the opening is aligned downward, so that the cap is automatically wrapped or pushed into the stopper of the bottle container. And supplied to the capper and attached to the plug.

  When aligning the small caps as described above in a certain direction, it is relatively easy to align the openings downward. For example, the cap has a center of gravity at the top surface, so if the cap is dropped from above in the hopper, the cap stops falling (landing with the top surface down) with the opening facing upward ) Is likely to increase. Using this phenomenon, when the caps are aligned in a fixed direction, the cap with the opening facing upward is sent to the next process as it is, and the cap with the top surface facing upward is not sent to the next process. It is usually done as removed and returned to the hopper.

  The caps sent to the next process are turned over with the top side facing up, and all the caps are aligned with the openings facing down and sent to the capper. As the inversion method, for example, there is a method described in Patent Document 1. In this method, the cap that is fed out from the cap aligning device drops the vertical chute part that drops the cap in the vertical state through the first cap direction changing part of the curve that changes the direction of the cap vertically. This is a method of setting the opening to the lower side in the second cap direction changing portion that makes the opening downward at the lower end of the chute.

  Patent Document 2 describes the use of a vibratory parts feeder as a conventional alignment method for aligning a plastic cap with a collar used as a stopper of a paper cup container so that its orientation is a constant direction ( 11 and 12). There is described a method in which the hooked cap is sequentially moved on the feed groove by vibration and aligned in the front and back directions, and those not in the desired direction are excluded as defective.

JP 2004-168508 A (page 20, FIG. 1) JP-A-6-298333 (FIGS. 11 and 12)

In the conventional cap alignment method based on the drop method, the top cap is removed as a defect from the cap in which the cap with the top portion on the top and the cap with the opening portion facing upward (the top portion is on the bottom) is mixed, and the opening portion is removed. Only the upward cap is supplied to the capper with its top surface turned upside down. Further, the method using the vibratory parts feeder is the same as the above except that the cap that has not been in the predetermined orientation is excluded as a defect, but there is a problem that the size of the cap is further limited.

Therefore, hereinafter, the component attitude control device, the component attitude control unit, the component selection / separation device, and the component alignment device are referred to as a cap attitude control device, a cap attitude control unit, a cap selection / separation device, and a cap alignment device, respectively.

First, a schematic perspective view of the first cap posture control device of the present invention is shown in FIG.
A cap posture control device 1 shown in FIG. 1 includes a cap insertion portion 2 of a truncated cone that inputs a cap (not shown), a cylindrical case 4 below the cap insertion portion 2, and a rotating drum 5 that is rotatably installed therein. And an attitude control unit 3.
The rotary drum 5 is composed of an upper spherical surface 5-1 and a lower cylinder 5-2. Above the rotary drum 5, a stirring bar 6 that stirs the charged cap and leveles it flatly on the spherical surface. A plurality of fins 7 are provided on the outer surface of the cylinder 5-2 substantially perpendicularly thereto. Further, as a cap storage cell 8 for storing a cap in a vertically oriented space between adjacent fins and the inner surface of the cylindrical case 4, a cap outlet 9 in a vertically oriented posture is provided at the bottom of the cylindrical case 4. ing.

  The cylinder 5-2 of the rotating drum 5 has an outer diameter that allows the cap to slide down the slope of the spherical surface 5-1, and to be stored in the cap storage cell 8 in a vertical orientation. Further, the inner surface of the cylindrical case 4 above the cap outlet 9 has a height slightly higher than the cap storage cell 8, and the cap storage cell 8 in which the cap has already been stored while the rotary drum 5 is rotating reaches the cap outlet 9. A cap drop prevention cell cover 10 is further formed to prevent the cap from further entering the cap storage cell 8 at the time. A cap dropping cylinder 11 for sending the cap to the next process is installed at the lower part of the cap outlet 9. The cap drop cylinder 11 is provided with a cap detection sensor 12 for dropping caps one by one and a shutter 13 that opens and closes in conjunction with the cap detection sensor 12. The vertically oriented cap in the cap dropping cylinder is sent to the next process.

In the example of FIG. 1, the cap insertion part 2 is formed in a truncated cone having a larger diameter at the upper part than at the lower part, but the shape may be a cylinder or other shapes, and is not particularly limited.
In the example of FIG. 1, the rotating drum 5 is formed in a cylindrical lower portion, but may be formed in a polygon that can be regarded as a cylindrical shape. In the example of FIG. 1, the upper part of the cylindrical lower part with the inclined surface formed in the entire circumferential direction is formed in a truncated cone, but a spherical surface (the whole surface may be a spherical surface or its top portion may be a flat surface) or a polygonal surface ( The shape is not particularly limited as long as the inclined surface has an inclined surface in the entire circumferential direction of the cylindrical lower portion, such as a polygonal pyramid, and the top portion thereof may be flat. The rotating drum 5 may be formed to have a height substantially the same as or lower than the upper end of the cylindrical case 4 even when the tip of the rotating drum 5 is in the cap insertion portion. The rotating drum 5 is formed to be rotatable in a cylindrical case.
In the example of FIG. 1, the stirring bar 6 is formed coaxially with the rotating shaft of the rotating drum so as to be rotatable above the rotating drum. It may be fixed to the inner wall of the input part. The installation height of the stirring bar on the rotating drum may be a height at which the cap can be stirred and the cap can be almost flattened on the inclined surface. The rotation (speed and direction) of the rotating drum and the stirring bar may be the same or different.

Next, an example of the second cap selective separation device of the present invention is shown in FIG.
FIG. 2 is a schematic cross-sectional view of the cap selective separation device 20. The cap selection / separation device 20 has either a box-shaped case 21 without a ceiling or a bottom for receiving a cap 25 in a vertical orientation, and surface detection sensors 22 (22-1 and 22-2) installed on the left and right sides thereof. It is comprised from the air cylinder 23 attached to the side surface. The air cylinder 23 fixes the case 21 and moves the case 21 in the left-right direction based on the surface states of the left and right plate surfaces of the cap 25 detected by the surface detection sensor 22 to selectively separate the cap of the desired plate surface. Has been installed for.

  The vertically oriented cap 25 is supplied from, for example, the cap dropping cylinder 10 of the cap posture control device 1 illustrated in FIG. In this case, the case 21 is disposed directly below the cap dropping cylinder (not shown). The case 21 moves on the support plate 24 in the left-right direction. For example, when a cap 25 having a desired plate surface is supplied to the side where the sensor 22-2 is installed in the case 21, the air cylinder 23 is driven by moving the cap 25 to move the case 21 to the right, and the support plate 24 It passes to the next process with the belt conveyor 27 through the acceptance cap conveyance path 26 provided in. Further, when the cap 25 having no desired plate surface is supplied to the sensor 22-1 installation side, the air cylinder 23 is driven to move the case 21 in the left direction by disabling the cap 25, and the cap 21 is provided on the support plate 24. It is discharged from the reject cap outlet 28 to the receiving box 29. With such a configuration, the cap selection / separation device can be made compact, which is advantageous in terms of cost.

The surface detection sensor 22 is a distance from the surface of a component such as a cap (interval with the sensor) due to light, sound, laser light reflection / entry / transmission , brightness, saturation, pattern, surface roughness, unevenness of the surface of the component. However, it is not particularly limited how the sensor is formed. It is not always necessary to install two sensors, and one sensor may be used depending on the surface condition of the parts.
The same applies to the following apparatuses.
The method for controlling the cap to the vertical orientation is not particularly limited, and examples include a method using the first cap posture control device of the present invention described above, a cap posture control unit shown in FIG. .

Finally, the third cap alignment apparatus of the present invention will be described.
FIG. 3 shows a schematic configuration diagram (cross-sectional view) of the cap alignment device.
The cap alignment device 30 includes a cap posture control unit 31 that controls the cap posture in the vertical direction, and a surface detection unit 33 (33-1, 33-2) that detects the surface state of the plate surface of the received cap in the vertical posture. The cap distributing unit 34 and the cap distributing unit 32 including the cap conveying path 35 (35-1, 35-2). The sorting means 34 is composed of a ceiling for receiving a cap in a vertical orientation, a box-like case 34-1 without a bottom, and a case moving means 34-3. The case 34-1 is arranged so that a cap 37 in a vertical orientation falling from the cap drop cylinder 11 of the cap posture control device 1 of FIG. 1 can be stored with the side surface (circumferential surface) facing the front of the device. .

  The surface detection means 33 is a sensor, and the case moving means 34-3 constituting the component sorting means 34 is an air cylinder. Further, the case 34-1 (shown in a perspective view in FIG. 4) is formed with flanges 34-2 on both sides of the upper end thereof. The eaves 34-2 serves as a shutter for preventing the cap dropping cylinder 10 from dropping and a cap waiting to be stored in the case 34-1 from dropping while the case 34-1 is moving. The formation and the number of sensors 33 are the same as those in the apparatus illustrated in FIG.

In the apparatus of FIG. 3, the cap attitude control unit 31 is the cap attitude control apparatus 1 illustrated in FIG. 1, and the configuration and operation of the apparatus are as described above. The cap sorting means 34 has the same structure and the same operation as the cap selection / separation apparatus illustrated in FIG. 2, but the cap on the desired plate surface and the cap on the other plate are passed and passed through the cap conveyance path 35. All caps differ in that the desired plate surface is aligned upward or downward.

Two cap conveyance paths 35 for conveying the cap 37 to a cap receiver 38 such as a lower conveyor belt are installed on the support plate 36 below the case 34-1. For example, the transport path 35 allows the cap 37 to pass therethrough in a vertically oriented posture with one opening on the right side and in the other with the opening in a vertically oriented posture with the left side on the other. It consists of two cap conveyance paths 35-1 and 35-2 that convey the cap receiver 38 (conveyor belt) in the posture. In FIG. 3, even if the cap 37 introduced into the case 34-1 is in a vertical orientation in which the opening is directed to either the left or right side, a cap posture conversion unit 35- that converts the posture of the cap provided in the middle of the conveyance path 35. 3. When the cap 37 is introduced into the conveyance paths 35-1 and 35-2 by passing through 35, 35-4 (in this example, the curved portion having an appropriate curvature corresponding to the size of the cap 37 is the posture changing portion). It is possible to land on the cap receiver 38 by changing the posture (vertical posture in which the opening is on the left and right sides) to the posture in which the opening is downward. When landing the cap 37 in the same posture as above with the opening facing upward, the cap 37 is bent in the opposite direction to that of FIG. This can be done by passing the posture changer. In this example, the conveyance path 35 is installed substantially perpendicular to the support plate 36, but the installation angle is not particularly limited as long as the cap is introduced and the conveyance path 35 can be conveyed downward.
Cap conveying path 35, the ribbon twisted is not particularly limited as long as the orientation of the cap 37 as it can convert as described above, the transport path in addition to the above examples twisted in the form of candy twist switchback type, the through passage Those formed in the formula and the like.

  FIG. 3 shows the case of the case 34-1 according to the state immediately before the detection by the sensors 33-1 and 33-2 and the detected surface state of the plate surface state of the cap 37 in the vertical orientation received in the case 34-1. The state in which the cap 37 is introduced into and passed through the cap conveyance path 35 by moving leftward or rightward is shown at the same time (the case 34-1 moved in either the left or right direction is not shown). When the surface state of the cap 37 is detected by the sensors 33-1 and 33-2, the air cylinder 34-3 operates in conjunction with the case 34-1 and moves the case 34-1 rightward or leftward along the support plate 36. When the cap 37 in the case 34-1 reaches the transport path entrance of the cap transport path 35-1 or 35-2, the cap 37 passes through one of the transport paths downward, and the air cylinder 34-3 causes the case 34- 1 returns to the position where the cap 37 is received from the cap dropping cylinder 11 of the cap posture control device 1 of FIG. When the cap 37 below the shutter 13 of the cap dropping cylinder 11 falls into the case 34-1, the sensor 12 operates to open the shutter 12, and the cap 37 is dropped onto the cap 37 in the case 34-1. The cap 37 that has landed on the belt conveyor 38 via the conveyance path 35 is sent to the next process.

  3 shows an example in which the cap posture control device illustrated in FIG. 1 is used as the cap posture control unit 31, but the caps are positioned so that the cap 37 is housed in the case 34-1 in a vertical direction. The unit having any attitude control method may be used as long as it has a mechanism for moving in a changing manner.

FIG. 3 shows an example in which the cap is distributed to one of the cap conveyance paths according to the surface state of the cap detected by moving the case 34-1 to the left or right. Another example is shown in FIG.
The cap aligning device 40 shown in FIG. 4 , which is a schematic cross-sectional view, is a cap reservoir, and a cap 43 that is vertically moved by a swinging rod 42 that moves up and down is guided to the lower end of the cap reservoir. Attitude control unit 41, sensors (45-1, 45-2) of surface detection means 45 provided at the lower end of attitude control unit 41, distribution means 46 below the attitude control unit, and conveyance path installed therein The cap distributing unit 44 is composed of 47. According to the surface state of the cap 43 detected by the surface detection unit 45, the shutter 46-1 that drops and introduces the cap 43 into the lower conveyance path 47 (47-1, 47-2). The switching damper 46-2 for distributing the cap 43 to either one of the cap transport paths 47-1 and 47-2 and a pair of guide plates 46-3 and 46-4 provided thereabove. The limited rotation of the shutter 46-1 and the switching damper 46-2 in the right direction or the left direction is linked to the detection of the surface state of the cap 43 by the sensor 45. The introduction of the cap 43 into the cap transport paths 47-1 and 47-2 according to the detected surface condition is due to the limited rotation of the switching damper 46-2 in the left-right direction. In this example, the surface detecting means 45 is incorporated in the cap posture control unit 41, but it may be formed separately from the cap posture control unit 41 as shown in FIG.

  Each device of the present invention has been described above by taking the cap as an example. However, as long as it is a substantially plate-like component with different surface states on the upper and lower plate surfaces other than the cap, the posture control and selective separation of the component can be performed similarly to the cap. In addition, all parts can be aligned with their plate surfaces aligned in a certain direction.
