The present invention relates to a component feeder capable of continuously and automatically feeding target components while aligning their postures in the same direction. Although it does not belong to the field, it does not belong to the field of manufacturing and providing a parts supply device that can automatically supply circular or similar flat plate parts with the same front and back posture. This includes, of course, the fields of manufacture and provision of items identified as having incorporated the creative content of the idea, as well as the transportation, storage, assembly and installation of such fields. From the field of providing and selling necessary equipment and instruments, to the field of providing materials, such as wood, stone, various fibers, plastics, and various metal materials required for those materials, machinery, and parts, The field of electronic parts incorporated in them and the control-related equipment that integrates them, the field of various measuring instruments, the field of power machines that operate the equipment and equipment, the electric power that is the energy and the electricity and oil that are the energy sources Fields that are generally collectively called industrial machinery, and furthermore, fields related to testing and researching those equipment and instruments, exhibiting, selling, importing and exporting them, and the results of their use and that In addition to the fields related to the collection and transportation of garbage generated by the operation of equipment and instruments for manufacturing, the recycling field that efficiently reuses such garbage, and new fields that cannot be imagined at this time. , there are hardly any unrelated technical fields.

(Point of interest)
The process of filling and packaging jam jars in a food factory consists of supplying the jars to a filling device, filling them with jam, supplying the jars to the handling section of a tightening device, attaching a twist cap to the bottle, and tightening the jam. In addition to jam jars, this process is similar to attaching screw caps to other food jars, and in any case, Since it is necessary to continuously supply twist caps or screw caps with the front sides facing upward to the handling part of the seam tightening device, parts supply equipment for caps is used when mass-producing bottled food. However, it is desirable for the parts supply device for caps to improve the efficiency of the sorting work for aligning the cap postures and to reduce the power and energy consumption required for sorting the cap postures. .

(conventional technology)
Reflecting this situation, it is not that there have not been some proposals that could serve as breakthrough measures.
For example, as typified by the one proposed in Patent Document 1 (1) below, which has already been developed by the applicant of the present application, the parts feed section at the bottom of the parts reservoir container is formed by connecting the outer peripheral side wall and the parts reservoir. A large number of parts, which are placed between the inner wall of the container and the inner wall of the container so as to secure a parts receiving space, are put into the parts receiving space and are thrown into the parts storage container, Annular grooves for leading out are formed so that parts can be continuously arranged and supplied, and parts can be discharged one by one at the ends of the grooves for leading out. In the part ejection direction of the ejection port, the part is aligned with the optimum position immediately after the whole shape is exposed, and the part is always rolled upward or downward on a predetermined surface side, whichever is the front or back. A part supply device that arranges a controllable fluid ejection part and delivers caps with the posture aligned, or a long shape and an eccentric position from the center in the longitudinal direction, as seen in Patent Document 1 (2) An article aligning device equipped with a spring for aligning elongated articles, which is movably provided and provided at an angle so that a large number of the articles are placed thereon and these articles can be slid down by their own weight. A disk, a guide plate installed below the disk in the direction of inclination to stop the article from sliding down, and a plurality of magnets installed on the disk at predetermined intervals in the moving direction of the disk. and the like are known.

In addition, as in Patent Document 1 (3), the peripheral edge of one top surface can be in contact with a plane perpendicular to the center line, and the vertical end surface shape of this peripheral edge is angular. The back surface is a device for supplying material that constitutes a snap button that does not satisfy this condition. A rotating disk having an engaging surface portion formed to have a slightly saw-toothed cross-section so that the edges rising inwardly to a predetermined range are sharp, and the periphery of this rotating disk is surrounded to accommodate the material inside. a guide member fixed to the main body and engaged with the engaging surface to guide the raised material in a predetermined direction; and the material guided by the guide member passes through the opening. and a passage member having passages guided downward from the main body in a single row, wherein the opening is wide enough to allow passage of material in either the forward or reverse direction. and the passage member is formed with a relief portion in which one side of the passage is inclined downward and the lower side of the passage is notched to leave a slight height and is opened in the main body. As shown in FIG. 3 of Patent Document 1 (3), a high portion and a low The difference between the portions is, for example, about 0.9 to 1.0 mm, and the material contained in the main body engages and rises when the side of the recess that is to be caught on the engaging surface contacts the engaging surface. However, the one facing the opposite direction will fall during the rising stage, and there are some snap button material supply devices that are capable of feeding the material aligned in the same direction.

However, the parts feeding device as shown in the former Patent Document 1 (1) requires sensors in order to identify the front and back of the parts. The supply of gas, compressed air, water, oil, and other fluids is indispensable, and it is necessary to prepare compressors, pumps, fluids, etc., leaving the disadvantage that the expenses required for equipment, electricity, and other running costs increase. In the article alignment device of Patent Document 1 (2), a centrifugal side provided with a magnet rotates an inclined disk, and a long part attracted to the magnet is lifted as the disk rotates. Therefore, it is possible to continuously apply potential energy to each long part and use it to unify the posture of each long part. It is not possible to unify the front and back of the twist cap just by using the structure that attracts the parts to the magnet, and it is like the snap button material supply device represented by Patent Document 1 (3). In this case, an engaging surface with a complex saw-toothed cross-sectional shape must be provided around the entire circumference of the rotating disk. However, there is a risk that the apparatus will become large in size, heavy in weight, and expensive.

A guide or the like may generate noise by vibrating the target part, or cause fine damage to the target part due to the vibration.

Furthermore, as a specific example, the curvature radius of the cross section of the outer peripheral edge of the disk-shaped back surface is set smaller than the curvature radius of the cross section of the outer peripheral angle of the top surface, and the center of gravity is made of magnetic material near the top surface. A component supply device for aligning target components in a front posture, wherein a cylindrical bowl is immovably supported in a tilted posture perpendicular to a sliding angle of 30° to 60° with respect to the horizontal, and the bowl is near the bottom has a disk-shaped conveying surface wall inclined at a slide-down angle of 30° to 60° with respect to the horizontal so that the object parts slide down to a depth position that can accommodate a plurality of the object parts of At a plurality of locations along the outer periphery of the bowl, there are disposed suction points embedded with permanent magnets for attracting target parts, and a conveying turntable provided with a rotational drive source for rotating the conveying surface wall is arranged, and the bowl On the peripheral wall, the target part is placed in the centrifugal direction, which is the 2 o'clock to 4 o'clock direction when the transfer surface wall rotates clockwise, and the 8 o'clock to 10 o'clock direction when the transfer surface wall rotates counterclockwise. A delivery port is opened, and a separation angle of 45° to 15° with respect to the horizontal from the upstream side to the downstream side is formed in the range from the delivery port to the center of the conveying surface wall. A front/back sorting tool having a peeling plate attached to the surface is arranged immovably, and the front/back sorting tool is symmetrical from the position of the suction point when the tip angle of the peeling plate coincides with the 12 o'clock direction of the center of the conveying surface wall. The 12 o'clock direction line passing through the center of the conveying surface wall, either at the 6 o'clock direction or between the centers of the conveying surface walls by the dimension exceeding the diameter of the part, and 3 o'clock to 6 o'clock or 6 o'clock It is arranged at a position where a straight line that inclines from the center of either one of the delivery ports at 9 o'clock to the horizontal line by 5° to 25° in the direction of 12 o'clock intersects, It has a peeling edge slightly closer to the 12 o'clock direction than the upstream end, a central end extending from the tip corner to the center of the conveying surface wall, and a sliding end extending from the center of the conveying surface wall at the central end to the downstream end of the delivery port. , In the front and back sorting tool, in the range from the center end to the delivery port in either the 9 o'clock or 3 o'clock direction, the uppermost rough sorting region near the tip corner and the 6 o'clock direction near the delivery port and a medium-level coarse sorting region between the coarse sorting region and the fine sorting region are arranged, and the rough sorting region has an edge thickness equal to the outer peripheral edge of the back surface of the target part set sufficiently larger than the radius of curvature of the cross section of the top surface and slightly smaller than the radius of curvature of the cross section of the outer peripheral angle of the same top surface, and the rough sorting edge directed toward the delivery port and the rail width are outside the back surface of the target part periphery is set to be sufficiently larger than the radius of curvature of the cross section of and slightly smaller than the radius of curvature of the cross section of the outer peripheral angle of the same top surface, and gently descends from the upper surface of the peeling plate to the delivery port beyond the rough sorting edge A sloped dampening rough rail is provided, and the average sorting zone has an edge thickness greater than the radius of curvature of the cross-section of the outer peripheral edge of the back surface of the target part and less than the radius of curvature of the cross-section of the outer peripheral corner of the same top surface.

It is set to be the same as or slightly larger than the curvature radius of the cross section of the outer peripheral edge of the back surface, and is set sufficiently smaller than the curvature radius of the cross section of the outer peripheral angle of the same top surface, and the fine selection edge toward the delivery port and the rail width are It is set to be the same as or slightly larger than the curvature radius of the cross section of the outer peripheral edge of the back surface of the target part, and sufficiently smaller than the curvature radius of the cross section of the outer peripheral angle of the same top surface, and the fine selection edge is set from the upper surface of the release plate. It is also possible to provide a parts supply device having a configuration in which a narrow buffer rail directed toward the delivery port and having a greater downward slope than the parallel buffer rail is provided.

As described above, according to the parts feeding apparatus of the present invention, unlike the conventional one, the sensor for determining the posture of the target parts and the air for sorting the target parts are provided by the unique characteristic configuration as described above. It eliminates the need for nozzles, etc., greatly simplifies the structure, achieves smaller size, lighter weight, energy saving, and space saving. , it operates quietly, and it is possible to obtain an excellent feature that the sorting accuracy and the efficiency of the sorting work can be raised to a higher level without damaging the target parts.

In addition, the front/back sorting tool of the component supply device of the present invention has a rough sorting area having a rough sorting edge at the uppermost position closest to the leading end corner on the peeling plate, and a rough sorting area closest to the downstream end of the delivery port. A fine sorting area having a fine sorting edge is arranged at the bottom, and a medium sorting area having a coarse sorting edge is arranged at an intermediate position between the rough sorting area and the fine sorting area. Therefore, in the process in which the target parts pass through the rough sorting area, the medium sorting area, and the fine sorting area in that order, the processes of rough sorting, medium sorting, and fine sorting are sequentially performed. It is possible to improve the sorting accuracy of parts.

In addition, if the rough sorting area has a rough buffering rail, the coarse sorting area has a rough buffering rail, and the fine sorting area has a fine buffering rail, the release plate slides down and enters the rough sorting area. Incoming target parts are guided to land on the coarse sorting edge while rolling smoothly on the cushioning rough rail to prevent them from bouncing against the coarse sorting edge and inadvertently falling off before being sorted. In addition, the target parts that have entered the normal sorting area are prevented from jumping on the normal sorting edge and inadvertently falling off before being sorted, and the normal sorting is performed while smoothly rolling on the buffer parallel rail. Object parts that are guided to land on the edge and also enter the fine sorting area are prevented from bouncing against the fine sorting edge and inadvertently falling off before being sorted, and on the buffer narrow rail. Since it is guided to land on the fine sorting edge while rolling smoothly, the number of target parts that inadvertently fall off from the rough sorting area, the coarse sorting area and the fine sorting area can be reduced. , it is possible to realize a more efficient sorting process with less loss.

Furthermore, the fine sorting edge of the fine sorting area of the front/back sorting tool is provided with a plurality of steps that descend sequentially from the center end toward the delivery port in a stepped manner, and the buffer thin rail has a rail width that is the same as that of the target parts. It is set to be slightly larger than the radius of curvature of the cross section of the outer peripheral edge of the back surface, much smaller than the radius of curvature of the cross section of the outer peripheral angle of the top surface, and has a gentle downward slope than the buffer rough rail in the rough sorting area. The sorting rail is provided on the upper surface of the peeling plate from the middle part of the narrow buffer rail toward the delivery port. As a result of the experiment, it was confirmed that the top surface of the target part delivered from the delivery port faces upward with a probability of 99.95% or more.

According to the component supply device of the present invention, which is provided with the multiple avoidance tool, the target components are unified and supplied at the stage before reaching the front/back sorting tool, so two or more target components can be supplied. Compared to the case where the parts are supplied to the front/back sorting tool while overlapping each other, the target parts to be sorted are not adversely affected by other target parts, so a more accurate and efficient sorting process is realized. become a thing.

According to the component supply device of the present invention, the stripping auxiliary tool is provided on the inner peripheral wall of the bowl facing the 12 o'clock direction of the front/back sorting tool. When the target part is conveyed from the 6 o'clock position to the 12 o'clock position on the board and the maximum potential energy is applied to the target part, the target part is forcibly separated from the suction point and directed toward the front and back sorting tool. It is controlled to slide down, and a more efficient sorting process can be realized.

According to the component supply device of the present invention, which is provided with a posture changing tool consisting of a reversal guide gutter and a posture control plate, the reverse side is sorted in an upward posture, the front and back sorting tool slides down, and the front and back sorting tool slides down, and is placed in the bowl in that posture. It is dropped at the 6 o'clock position, and the rear surface is again attracted to the suction point of the conveying turntable with the upward posture, and the inefficient operation of being conveyed at 12 o'clock is eliminated. In the process of dropping from the tool, the reversing guide trough and the attitude control plate work together to automatically reverse the top surface and the back surface of the target part and drop it at the 6 o'clock position in the bowl, When the target part is sucked to the suction point of the conveying turntable, the probability of the target part being sucked with the top surface facing upward is remarkably increased, and more efficient sorting can be realized. becomes.

The front/rear sorting tool has a base end facing the delivery port connected to the inner peripheral wall of the bowl, and the rotary drive source has a tip protruding from the conveying surface wall of the conveying rotary plate of the output shaft of the front/rear sorting tool. The front/back sorting tool is rotatably supported by a bearing housed in a bearing box integrated at the central end, and the front/back sorting tool is supported in a manner bridged between the inner peripheral wall of the bowl and the output shaft of the rotary drive source. According to the parts supply apparatus of the present invention, the bearing box supports the tip end of the front/back sorting tool whose base end is supported by the inner peripheral wall of the bowl, and the rotary motion of the conveying turntable is carried out. The support strength of the front/back sorting tool can be greatly increased without hindering the front/back sorting tool. Since it supports with sufficient strength, strength parts for individually supporting each of the front/back sorting tool and the bearing box are not required, the number of parts can be reduced, and significant weight reduction and cost reduction can be achieved.

In carrying out the present invention having the configuration as described above, the best or desirable mode will be explained.
The bowl surrounds the outer circumference of the conveying turntable, encloses a plurality of target parts in a cylindrical shape that can be accommodated in random postures, and only the target parts that have passed through the front and back sorting tools and are sorted out. The bowl has a cylindrical shape capable of accommodating a plurality of the target parts, and has an inclined posture orthogonal to the sliding angle at which the target parts slide down with respect to the horizontal. and its peripheral wall has a 2 o'clock to 4 o'clock direction when the conveying surface wall rotates clockwise, and an 8 o'clock to 10 o'clock direction when the conveying surface wall rotates counterclockwise. The centrifugal side of the bowl must have a delivery port through which the target parts can be delivered. It should be immovably supported in a posture, i.e., at an angle of 120° to 150° to the horizontal. The height difference between the 6 o'clock position and the 12 o'clock position of the turntable becomes too small, and there is a risk that sufficient potential energy necessary for sorting cannot be obtained. The bowl approaches a horizontal position, making it difficult for the target parts to gather at the 6 o'clock position of the conveying turntable, and moreover, it is easy for the parts to overflow from the upper end opening of the bowl. There is a risk of causing the drawback that the
Further, as shown in the embodiments described later, it is desirable that the upper end opening of the bowl serves as a supply port for the target parts, and that an open/close lid is attached, and the open/close lid accommodates the target parts. It is preferable to use a transparent material such as a transparent synthetic resin so as to facilitate confirmation of the amount and storage state, confirmation of the sorting operation, and the like.

The conveying turntable converts a part of its rotational drive energy into the potential energy of the target part, and has the function of supplying the target part from above toward the front/back sorting tool from above, and the angle at which the target part slides down. At a plurality of locations along the circumferential direction of a disk-shaped conveying surface wall inclined at an angle, suction points for picking up the target parts must be arranged, and a rotary drive source for rotating the conveying surface wall must be provided. Instead, the conveying surface wall should be centered on the cylindrical center of the bowl and be inclined at a sliding angle of 30° to 60°, preferably 45°, to the horizontal. When the inclination angle of the conveying surface wall is less than 30° with respect to the horizontal, it is difficult to smoothly and quickly slide down the target part, and the inclination angle of the conveying surface wall is 60° with respect to the horizontal. If the angle exceeds 100°, the target part will slide down too quickly, and in any case, there is a risk of deteriorating the sorting accuracy.

The conveying turntable has a smooth surface that does not hinder the smooth sliding of the target component, and is spaced from the diameter of the disc-shaped target component on the centrifugal side of the disc-shaped diameter of the transport surface wall. along the circumference of the centrifugal side of the conveying surface wall, at intervals equal to the diameter of the target part plus the interval, as a suction point Permanent magnets are preferably embedded in the conveying surface wall so as to be flush with each other, each attraction point is replaced with a permanent magnet, and a suction pipe runs through the conveying surface wall in the thickness direction. The suction port of each suction pipe may be exposed flush with the surface of the air compressor, and the base end of each suction pipe may be connected to the pipe line of the suction side of the air compressor.

The front/back sorting tool is attracted to each suction point, is guided in an arc along with the rotation of the conveying surface wall, and is conveyed from the center of the conveying rotary plate to a position in the 12 o'clock direction. Among the target parts that are peeled off from the suction point in order of coming, losing the suction power and sliding down, only those whose back surface is grounded and whose top surface is facing upward are selected and sent from the delivery port, and the top surface is facing upward. The one that is grounded and whose back surface is facing upward has the function of guiding it to fall into the bowl, and has a peeling plate in the range from the delivery port to the center of the conveying surface wall and is immovable. When the release plate is aligned with the 12 o'clock direction of the center of the conveying surface wall, it is located in the 6 o'clock direction by the dimension exceeding the diameter of the target part from the position of the suction point. a central edge extending from the center of the transport surface wall to the tip angle, and a stripped edge extending from the tip angle to the upstream end of the delivery port, having a tip angle somewhere between a position or the center of the transfer face wall; and a slide-down end extending from the center of the conveying surface wall at the central end to the downstream end of the delivery port, and the release plate has an edge thickness above the tip corner and the outer peripheral edge of the back surface of the target part.

To give a more specific example of the front/back sorting tool, as shown in the embodiments described later, the range from the delivery port to the center of the conveying surface wall is oriented from the upstream side to the downstream side of the conveying surface wall. When a peeling plate is disposed immovably with a separation angle of 45° to 15° with respect to the horizontal, and the tip angle of the peeling plate coincides with the 12 o'clock direction of the center of the conveying surface wall a 12 o'clock direction line between the position of the suction point and the 6 o'clock direction by a dimension exceeding the diameter of the target part or the center of the conveying surface wall and passing through the center of the conveying surface wall; It is arranged at a position where a straight line inclined from the center of either 3 o'clock to 6 o'clock or 6 o'clock to 9 o'clock in the 12 o'clock direction from the center of the delivery port to the horizontal line at 5 ° to 25 ° intersects, and the peeling The plate has a stripped edge extending slightly from the apex corner to the 12 o'clock direction from the upstream end of the delivery port, a central edge extending from the apex angle to the center of the conveying surface wall, and a central end extending from the center of the conveying surface wall. and a slide-down end reaching the downstream end of the delivery port, and the front/rear sorting tool has a tip near the tip corner within the range from the central end to the delivery port in either the 9 o'clock or 3 o'clock direction. A top rough sorting area, a bottom fine sorting area close to the delivery port and close to the 6 o'clock direction, and a medium coarse sorting area between the rough sorting area and the fine sorting area. In the rough sorting area, the edge thickness is set to be sufficiently larger than the radius of curvature of the cross section of the outer peripheral edge of the back surface of the target part and slightly smaller than the radius of curvature of the cross section of the outer peripheral corner of the same top surface. The rough sorting edge directed to the exit and the rail width are set sufficiently larger than the radius of curvature of the cross section of the outer peripheral edge of the back surface of the target part and slightly smaller than the radius of curvature of the cross section of the outer peripheral angle of the top surface, A cushioning rough rail is provided that extends from the upper surface of the release plate beyond the rough sorting edge toward the delivery port and slopes gently downward, and the edge thickness of the rough sorting area is the outer peripheral edge of the back surface of the target part. Larger than the radius of curvature of the cross section and smaller than the radius of curvature of the cross section at the outer peripheral angle of the same top surface, and the average sorting edge directed to the delivery port and the rail width are set to the cross section of the outer peripheral edge of the back surface of the target part. larger than the radius of curvature and smaller than the radius of curvature of the cross-section of the same top surface peripheral angle, directed from the upper surface of the release plate beyond the coarse sorting edge, toward the delivery port, and sufficiently beyond the buffer rough rail A buffer parallel rail with a large downward slope is provided. corner cross-section curvature is set sufficiently smaller than the radius, and the narrowing edge toward the delivery port and the rail width are the same as or slightly larger than the curvature radius of the cross section of the outer peripheral edge of the back surface of the target part, and the same top surface A buffer strip set sufficiently smaller than the radius of curvature of the cross-section of the outer peripheral corner, directed from the upper surface of the release plate beyond the screening edge, toward the delivery port, and sloping further down than the buffer parallel rail. A rail should be provided.

If the angular posture of the peeling plate of the front/back sorting tool exceeds 45° with respect to the horizontal, there is a risk that the sliding speed of the target parts will become too high, making high-precision sorting difficult. On the other hand, if the angle is less than 15°, it becomes difficult to smoothly and quickly slide down the target parts, and in either case, there is a possibility that rapid and highly accurate sorting becomes difficult.
Also, when the tip angle of the release plate is aligned with the 12 o'clock direction of the center of the conveying surface wall, the distance between the position of the suction point and the 6 o'clock direction by the dimension exceeding the diameter of the target part or the center of the conveying surface wall 5 in the 12 o'clock direction with respect to the horizontal line from the 12 o'clock direction line passing through the center of the conveying surface wall and the center of the delivery port at either 3 o'clock to 6 o'clock or 6 o'clock to 9 o'clock The reason why it is preferable to arrange the apex angle at a position that satisfies the condition of intersection with a straight line inclined by 25° to 25° is that the apex angle is in the 12 o'clock direction line passing through the center of the conveying surface wall and in the 12 o'clock direction with respect to the horizontal line. and a straight line inclined at an angle of less than 5°, the inclination of the stripping edge toward the delivery port becomes too small, and even if the target part comes in contact with the stripping edge, it does not go to the delivery port. It does not roll smoothly, and there is a risk of it falling in the direction opposite to the delivery port (upstream direction of rotation of the conveying surface wall). On the other hand, when the stripping edge is arranged at a position where it intersects with a straight line that inclines more than 25° in the 12 o'clock direction, the inclination of the stripping edge toward the delivery port becomes too large, and the target part in contact with the stripping edge is broken. In either case, highly accurate sorting can be efficiently carried out because there is a risk that the sorting areas of the rough sorting area and the fine sorting area cannot be tracked accurately, and the sorting areas can rapidly fall toward the delivery port. It has the disadvantage of being difficult.

As will be shown in the examples to be described later, the rough screening edge, the coarse screening edge, and the fine screening edge are all formed by the thickness of the plate-like member oriented in the 12 o'clock direction, which is superimposed and bonded to the top surface of the release plate. In addition to the thick portions (each thick edge portion), it can be a thick portion (each thick edge portion) directed in the 12 o'clock direction of a rod-shaped material having a rectangular cross section superimposed and joined to the top surface of the release plate. Each of the rough buffer rail, parallel buffer rail, and narrow buffer rail can be rod-shaped or pipe-shaped, and can be made of plate-shaped parts set to the width of each rail. The upper end edge in the 12 o'clock direction may have a cylindrical surface shape, a polygonal tube shape, or the like.
Then, as shown in an embodiment to be described later, the fine sorting area of the front/back sorting tool is provided with a plurality of steps in which the fine sorting edge descends from the central end in a stepwise manner toward the delivery port. The rail width of the narrow buffer rail is set to be slightly larger than the radius of curvature of the cross section of the outer peripheral edge of the back surface of the target part, and much smaller than the radius of curvature of the cross section of the outer peripheral corner of the same top surface. A final sorting rail having a gentler downward slope than the coarse rail may be provided on the upper surface of the release plate from the middle portion of the parallel buffer rail toward the delivery port.

As shown in FIGS. 2 and 9, the component supply apparatus 1 of the present invention having the above structure opens the arcuate door portion 48 of the opening/closing lid 46, for example, about 300 twist caps TC, TC, . . . is put into the bowl 4, the arc-shaped door portion 48 is closed, and when a start operation is performed via a control panel (not shown), the gear motor 3 slowly rotates the conveying turntable 2 in the counterclockwise direction RD, The twist caps TC, TC, . . . , . . . , is lifted up to the 3 o'clock and 2 o'clock positions along the outer peripheral edge of the conveying surface wall 20, and as shown in FIGS. At this time, the upper twist cap TC overlapping the twist cap TC comes into contact with the expulsion plate EX and is dropped in the 6 o'clock direction, and the single twist that is directly grounded and attracted to the conveying surface wall 20 Only the cap TC passes under the expulsion plate EX, is moved in the 12 o'clock direction, and is given potential energy.

As shown in FIGS. 10 and 15, the twist cap TC, which is in contact with the guide plate GP of the auxiliary peeling tool PA beyond the 12 o'clock position of the transport surface wall 20, is blocked and the transport surface wall 20 is blocked. , the position energy is released, and while sliding down, it rides on the peeling edge 51 of the peeling plate 5 of the front/back sorting tool FS, and as shown in FIGS. is grounded on the peeling plate 5, the top surface outer peripheral angle SE of the twist cap TC is first engaged with the buffer rough rail 61 of the rough sorting area 6, and if it is not hooked, the sliding end 53, and if it is latched, it rolls while engaging the buffer rough rail 61; , when hooked, it rolls over the side of the coarse sorting area 7 while engaging the rough sorting edge 60, is engaged with the buffering rail 71 of the coarse sorting area 7, and slides down if it is not latched. It slides down towards the end 53 and, if latched, engages the average sorting edge 70; It rolls over the sorting zone 8 while engaging the sorting edge 70, engages the buffer strips 81 of said fine sorting zone 8, and, if not latched, slides down towards the slide-off end 53 where it is latched. If it is caught, it rolls while being engaged with the buffer thin rail 81, is engaged with the final sorting rail 82, and if not latched, slides down toward the sliding end 53. The fine sorting edge 80 rolls on the other side while engaging the final sorting rail 82, and the fine sorting edge 80 almost certainly does not engage with the top surface outer peripheral angle SE of the twist cap TC, and the sliding end 53 does not. The twist cap TC slid down to the slide-down end 53, as shown in the two-dot chain line arrow in FIG. 10 and in FIG. , and landed in a posture where the back surface BS is grounded near the 6 o'clock position of the conveying surface wall 20 while contacting the attitude control plate AB waiting for the drop destination, The twist cap TC, whose rear surface BS is thus grounded to the conveying surface wall 20, is sucked again by the sucking point 23 and conveyed counterclockwise toward the twelve o'clock direction.
In this way, the twist cap TC, whose top surface SF is grounded to the peeling plate 5, rolls down alternately on smooth slopes and stairs in the order of the rough sorting area 6, the coarse sorting area 7 and the fine sorting area 8. Since it slides down while moving and the potential energy is gradually released, the impact force at the time of falling is greatly reduced, deformation and damage can be prevented more reliably, and quietness is greatly improved. .

Further, as shown in FIGS. 12 and 13, the twist cap TC is moved in the 12 o'clock direction of the transfer surface wall 20, and the twist cap TC to which potential energy is applied moves beyond the 12 o'clock position of the transfer surface wall 20 to the auxiliary peeling tool. When it comes into contact with the guide plate GP of the PA and is dammed, it deviates from the adsorption point 23 of the transfer surface wall 20, the potential energy is released, and when it slides down, it rides on the peeling edge 51 of the peeling plate 5 of the front/back sorting tool FS, When the twist cap TC has its back surface BS grounded to the release plate 5, the back surface peripheral angle BE of the twist cap TC is first hooked to the buffer coarse rail 61 of the coarse sorting area 6, and the It rolls while engaging the buffer rough rail 61 , engages the rough sorting edge 60 , rolls to the side of the coarse sorting area 7 , rolls while engaging the buffer common rail 71 of the coarse sorting area 7 , and the coarse sorting edge 70 . , rolling over the fine sorting zone 8, rolling while engaging the buffer narrow rails 81 of the fine sorting zone 8, rolling against the fine sorting edge 80 while engaging the final sort rail 82, The twist cap TC, which rolls along the fine sorting edge 80, passes through the delivery port 43, and has the top surface SF facing upward, is delivered to the upper end of the sliding guide rail GL through the turning path LD, and further the twist cap TC is , being guided by the sliding guide rail GL by its own weight, it is automatically supplied to the handling section of the automatic lid-covering device (not shown) below.

Further, as shown in FIG. 12, when the sliding guide rail GL is filled with the twist caps TC, TC, . automatically stops the rotation of the gear motor 3, and automatically restarts the rotation of the gear motor 3 when the sensor detects the decrease of the twist cap TC of the sliding guide rail GL. can be controlled to
