Description
[Technical field]
[0001] This invention relates to a parts supplying device capable of automatically supplying target parts continuously by aligning the postures of the target parts in the same direction, and in particular includes the fields of manufacturing and providing parts supplying devices capable of automatically supplying parts having a flat circular outer shape or a similar flat shape such as screw caps, lug caps, and twist caps by aligning the postures of the front and back of the parts in the same direction, as well as the fields of manufacturing and providing items that do not belong to the above fields but are identified as incorporating the creative content of the technical ideas therein. It also includes the fields of providing and selling equipment and tools required for the transportation, storage, assembly, and installation in these fields, as well as the fields of providing and selling the equipment and tools required for the above fields, as well as the materials, machinery, and parts, such as There is virtually no technical field that is not related to this industry, including fields that provide wood, stone, various textiles, plastics, various metal materials, etc., the electronic components that are incorporated into these and the control equipment that integrates them, various measuring instruments, the power machinery that drives the equipment and tools, the electricity that provides the energy, and the electricity and oil that are the energy sources for these, as well as fields that are generally referred to as industrial machinery, as well as fields that test, research, exhibit, sell, import and export such equipment and tools, fields related to the collection and transportation of waste generated as a result of their use or from the operation of the equipment and tools used to make them, the recycling field that efficiently reuses such waste, and even new fields that cannot be imagined at this time. [Background technology]
[0002] (Point of interest) The process of filling and packaging jam jars in food factories typically involves supplying the bottles to a filling device where they are filled with jam, then supplying them to the handling section of a seaming device where twist caps are attached to the bottles and seaming them. Similar processes are also followed when attaching screw caps to other food bottles, in addition to jam jars. In either case, it is necessary to continuously supply twist caps or screw caps with their front side facing up to the handling section of the seaming device. Therefore, when mass-producing bottled foods, a cap parts supply device needs to be installed. However, it is desirable for the cap parts supply device to be able to increase the efficiency of the sorting work to align the caps, as well as to reduce the power and energy consumption required to sort the cap positions.
[0003] (Prior Art) Reflecting this situation, it is not surprising that a number of proposals have been made to date that serve as solutions to the problem. For example, as proposed in the following Patent Document 1 (1), which the applicant of the present application claims to have already developed, a part feed section at the bottom of a parts storage container is disposed between the outer peripheral side wall of the part feed section and the inner wall of the parts storage container so as to secure a parts receiving space, and a circularly-arranged outlet channel is formed in the parts receiving space so as to continuously arrange and supply a large number of parts that are placed in the parts storage container and require distinction between their front and back sides, while a discharge port is formed at the end of the outlet channel so as to be able to discharge parts one by one and which is also equipped with a parts front / back detection section, and the parts are discharged from the outlet channel at an optimal position immediately after the entire shape is exposed in the part discharge direction. Also known is a parts supplying device that has a fluid ejection section that can control the parts to roll over so that a specific side, either the front or back, always faces upward or downward, and sends out the parts with the caps aligned. Also known is an article alignment device for aligning long objects that have a long shape and a spring located eccentrically from the center in the longitudinal direction, as seen in Patent Document 1(2), which has a movable circular plate on which a large number of the objects are placed and which is tilted so that the objects can slide down under their own weight, a guide plate installed below the inclined side of the circular plate to stop the objects from sliding down, and a plurality of magnets installed on the circular plate at predetermined intervals in the direction of movement of the circular plate.
[0004] Also, as in Patent Document 1 (3), a device for supplying material for forming snap buttons in which the peripheral portion of one top surface can be made to contact a plane perpendicular to the center line, the vertical end face shape of this peripheral portion is angular, and the back surface of the other side does not satisfy this condition, is provided with a turntable that is arranged with the top surface tilted upward and rotated in a predetermined direction, and has an engagement surface portion formed so that the side that rises inward from at least the peripheral portion of the front surface to a predetermined range has a slightly sawtooth cross section, a main body that surrounds the periphery of the turntable and stores the material therein, a guide member that is fixed to the main body and engages with the engagement surface portion to guide the rising material in a predetermined direction, and a passage member that has a passage through which the material guided to the guide member is guided downward from the main body in a line through an opening. In such a case, the opening is wide enough to allow materials in either the forward or reverse direction to pass through, and the passage member has an escape portion formed in the main body by cutting out the lower end of the passage that slopes downward leaving only a small height, and as shown in Figure 3 of the same patent document 1(3), the difference between the high and low parts of the engagement surface part, which has a sawtooth cross section in the annular part near the periphery of the turntable, is, for example, about 0.9 to 1.0 mm, and when the side of the recess that will be caught by the engagement surface comes into contact with the engagement surface, the material contained in the main body engages with it and rises, but material in the opposite direction falls during the rise, and so snap button material supplying devices capable of delivering materials aligned in the same direction are often seen.
[0005] However, the parts supply device as shown in the former Patent Document 1(1) requires sensors to distinguish between the front and back of the parts, and the fluid ejection section that changes the direction of the parts requires the supply of inert gas, compressed air, water, oil, or other fluids, which requires the preparation of compressors, pumps, fluids, etc., leaving the drawback of high equipment expenses and high running costs such as electricity. The article alignment device in Patent Document 1(2) has a magnet on the centrifugal side and rotates an inclined disk, and the long parts attracted to the magnet are raised as the disk rotates, so that the position energy is continuously applied to each long part. It is possible to apply a magnet to each long part and use this to standardize the posture of each part. However, simply using a structure in which parts are attracted to an inclined circular magnet in this way does not allow the front and back of the twist cap to be standardized. Furthermore, a material supply device for snap buttons, such as that shown in Patent Document 1 (3), requires an engagement surface with a complex sawtooth-like cross-sectional shape around the entire circumference of the turntable. If a similar structure were to be used to select the front and back of a twist cap, the material supply device itself would become large and heavy, and would be expensive. [Patent Document 1] (1) JP 2002-19950 A (2) JP 7-285650 A (3) JP 58-18634 A Summary of the Invention [Problem to be solved by the invention]
[0006] (problem awareness) As described above, the various parts supplying devices proposed up to now all require complex, large, and heavy structures in order to fully perform their functions, which increases manufacturing costs and requires a large installation space. In addition, although not mentioned in the above patent documents, conventional vibration-type parts feeders, which apply vibrations to target parts to guide the target parts into alignment, generate noise when the target parts are vibrated and may cause fine scratches on the target parts due to the vibrations. Furthermore, devices that engage moving protrusions with target parts to align the target parts have the disadvantage that the engaging fittings may damage the target parts. In view of these current circumstances, the applicant of the present application has come to realize the need for the development of a new parts supplying device that is simpler, lighter, and can operate quietly, does not damage the target parts, has a high level of sorting accuracy and efficiency of the sorting work, can significantly reduce manufacturing costs, and can be installed in a smaller space.
[0007] (Objective of the Invention) Therefore, based on the determination that it would be possible to develop a new parts supplying technology that would simplify the structure, reduce weight, save energy and space, operate quieter, and achieve even higher levels of sorting accuracy and efficiency of the sorting process without damaging the target parts, we quickly began research and development into this technology, and after a long period of trial and error and numerous prototypes and experiments, we have now finally succeeded in realizing a parts supplying device with a new structure.

In the process of the target part being peeled off from the suction point and falling so as to sequentially engage with the coarse sorting edge of the coarse sorting area or the fine sorting edge of the fine sorting area, the target part whose outer peripheral edge of the top surface comes into contact with either the coarse sorting edge or the fine sorting edge slides down in the 6 o'clock direction inside the bowl, and the target part whose outer peripheral corner of the back surface comes into contact with the coarse sorting edge or the fine sorting edge slides down in the 6 o'clock direction inside the bowl,The parts are rolled down the coarse sorting edge or the fine sorting edge, and fed out from the feed outlet.
[0011] More specifically, this is a component supplying device that aligns target components, in a front position, in which the radius of curvature of the cross section of the outer periphery of the disc-shaped back surface is set to be smaller than the radius of curvature of the cross section of the outer periphery of the top surface, and a cylindrical bowl is supported immovably in an inclined position perpendicular to the sliding angle at which the target components slide down relative to the horizontal, and has a disc-shaped conveying surface wall inclined at the sliding angle at a depth position near the bottom of the bowl, suction points for suctioning the target components are provided at multiple points along the outer periphery of the conveying surface wall, and a conveying turntable is provided with a rotary drive source for rotating the conveying surface wall, and the conveying surface wall is fixed to the peripheral wall of the bowl, and the conveying surface wall is inclined at a depth position near the bottom of the bowl, in which the suction points for suctioning the target components are provided at multiple points along the outer periphery of the conveying surface wall.

[0012] As a more specific example, a component supplying device that aligns target components made of a magnetic material with a center of gravity closer to the top surface in a front position, in which the radius of curvature of the cross section of the outer periphery of the disk-shaped back surface is set to be smaller than the radius of curvature of the cross section of the outer periphery of the top surface, and in which a cylindrical bowl is supported immovably in an inclined position perpendicular to the horizontal at a sliding angle of 30° to 60°, and has a disk-shaped conveying surface wall that is inclined at a sliding angle of 30° to 60° with respect to the horizontal so that the target components slide to a depth position close to the bottom of the bowl that can accommodate a plurality of the target components, and has a plurality of conveying surface walls at multiple locations along the outer periphery of the conveying surface wall. A conveying turntable is provided with an attraction point having a permanent magnet embedded therein for attracting the target parts, and a rotary drive source for rotating the conveying wall is provided, and a delivery outlet is opened in the peripheral wall of the bowl, which can deliver the target parts in a centrifugal direction, that is, in the 2 o'clock to 4 o'clock direction when the conveying wall rotates clockwise, and in the 8 o'clock to 10 o'clock direction when the conveying wall rotates counterclockwise, and a front / back sorting tool is fixedly disposed in the range from the delivery outlet to the center of the conveying wall, the front / back sorting tool having a peeling plate that forms a separation angle of 45° to 15° with respect to the horizontal from the upstream side of the rotation to the downstream side of the rotation with respect to the conveying wall. The front and back sorting tool is disposed at a position where the tip angle of the peeling plate is between a position in the 6 o'clock direction by a dimension exceeding the diameter of the target part from the position of the suction point when the tip angle of the peeling plate is aligned with the 12 o'clock direction of the center of the conveying wall, and the center of the conveying wall, and further, where a 12 o'clock direction line passing through the center of the conveying wall intersects with a straight line inclined at 5° to 25° in the 12 o'clock direction from the center of the delivery outlet at either 3 o'clock to 6 o'clock or 6 o'clock to 9 o'clock with respect to the horizontal line, and the peeling plate has a peeling edge extending from the tip angle to a position slightly toward the 12 o'clock direction from the upstream end of the delivery outlet, and a peeling edge extending from the tip angle to the The front and back sorting tool has a central end that reaches the center, and a sliding end that reaches from the center of the conveying surface wall at the central end to the downstream end of the discharge outlet, and is arranged with a top coarse sorting area near the tip corner within a range from the central end to the discharge outlet in either the 9 o'clock or 3 o'clock direction, a bottom fine sorting area that is near the discharge outlet and in the 6 o'clock direction, and a middle normal sorting area that is between the coarse sorting area and the fine sorting area, and the coarse sorting area has an edge thickness that is 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 top surface, and is directed toward the discharge outlet, andA buffer coarse rail is provided, the rail width of which is 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 top surface, and which has a gentle downward slope from the upper surface of the peeling plate over the rough sorting edge toward the discharge outlet, and the parallel sorting area includes a parallel sorting edge having an edge thickness larger than the radius of curvature of the cross section of the outer peripheral edge of the back surface of the target part and smaller than the radius of curvature of the cross section of the outer peripheral corner of the top surface, which is directed toward the discharge outlet, and a rail width of which is larger than the radius of curvature of the cross section of the outer peripheral edge of the back surface of the target part and smaller than the radius of curvature of the cross section of the outer peripheral corner of the top surface, which is directed from the upper surface of the peeling plate over the parallel sorting edge toward the discharge outlet, and The component supply device may be configured such that a buffer parallel rail having a sufficiently larger downward gradient than the impact parallel rail is provided, and the fine sorting area is provided with a fine sorting edge having an edge thickness set to be the same as or slightly larger than the radius of curvature of the cross section of the outer periphery of the back surface of the target component and sufficiently smaller than the radius of curvature of the cross section of the outer periphery corner of the top surface, facing the delivery outlet, and a buffer narrow rail having a rail width set to be the same as or slightly larger than the radius of curvature of the cross section of the outer periphery of the back surface of the target component and sufficiently smaller than the radius of curvature of the cross section of the outer periphery corner of the top surface, extending from the upper surface of the peeling plate over the fine sorting edge toward the delivery outlet, with an even larger downward gradient than the buffer parallel rail. Effect of the Invention
[0013] As described above, the part supply device of this invention differs from conventional devices in that, due to its unique and characteristic configuration as described above, it does not require sensors to determine the posture of the target part or air nozzles to sort the target part, thereby significantly simplifying the structure and achieving smaller size, weight reduction, energy savings and space savings. Furthermore, it does not require vibration devices or engaging parts to hook and sort the target parts, so it operates quietly and has the outstanding characteristic of being able to achieve a higher level of sorting accuracy and efficiency of the sorting work without damaging the target parts.
[0014] In addition, the front and back sorting tool of the component supplying device of the present invention has a peeling plate in which a coarse sorting area having a coarse sorting edge is arranged at the top closest to the tip angle, a fine sorting area having a fine sorting edge is arranged at the bottom closest to the downstream end of the delivery outlet, and a parallel sorting area having a parallel sorting edge is arranged in the middle between the coarse sorting area and the fine sorting area.As the target parts pass through the coarse sorting area, the parallel sorting area and the fine sorting area in this order, they sequentially go through the processes of coarse sorting, parallel sorting and fine sorting, thereby further improving the sorting accuracy of target parts with their top surfaces facing upward.
[0015] In addition, a system having a buffer coarse rail in the coarse sorting area, a buffer parallel rail in the parallel sorting area, and a buffer parallel rail in the fine sorting area prevents target parts that slide down the peeling plate and enter the coarse sorting area from bouncing off the coarse sorting edge and falling off inadvertently before being sorted, and guides the target parts to land on the coarse sorting edge while smoothly rolling on the buffer coarse rail. Also, a system having a buffer parallel rail in the coarse sorting area prevents target parts that enter the parallel sorting area from bouncing off the parallel sorting edge and falling off inadvertently before being sorted, and the buffer parallel rail The target parts which enter the fine sorting area are prevented from bouncing off the fine sorting edge and inadvertently falling off before being sorted, and are guided to land on the fine sorting edge while rolling smoothly on the buffer narrow rail. This reduces the number of target parts which inadvertently fall off from the coarse sorting area, the normal sorting area and the fine sorting area, and enables the realization of a more efficient sorting process with less loss.
[0016] Furthermore, the fine sorting edge of the fine sorting area of the front and back sorting tool has multiple steps that descend in a stepped manner from the central end toward the send-out outlet, and the buffer thin rail has a rail width that is set to be very slightly larger than the radius of curvature of the cross section of the back surface outer edge of the target part and much smaller than the radius of curvature of the cross section of the top surface outer corner of the same, and a final sorting rail with a gentler downward slope than the buffer coarse rail of the coarse sorting area is provided from the middle of the buffer thin rail toward the send-out outlet on the upper surface of the peel-off plate, which further improves the accuracy of the sorting process of target parts whose top surfaces face upward in the fine sorting area, and experiments have confirmed that there is a probability of more than 99.95% of target parts sent out from the send-out outlet facing upward.
[0017] According to the component supply device of the present invention, which is equipped with a multiple avoidance tool, the target components are singulated and supplied before they reach the front / back sorting tool. This means that the target components being sorted are not adversely affected by other target components, as compared to when two or more target components are supplied to the front / back sorting tool while overlapping, resulting in a more accurate and efficient sorting process.
[0018] According to the component supply device of the present invention, in which a peeling auxiliary tool is provided on the inner wall of the bowl facing the front / back sorting tool at the 12 o'clock position, the target component adsorbed to the suction point of the conveying turntable is transported from the 6 o'clock position to the 12 o'clock position of the conveying turntable, and at the time when the maximum potential energy is imparted to the target component, the target component is forcibly detached from the suction point and controlled to slide toward the front / back sorting tool, thereby realizing a more efficient sorting process.
[0019] The component supply device of the present invention, which is equipped with a posture change tool consisting of an inversion guide gutter and a posture control plate, eliminates the inefficient operation of sorting a part with its back surface facing up, sliding off the front / back sorting tool and dropping at the 6 o'clock position in the bowl in that position, where it is then picked up at the suction point of the transport turntable with its back surface facing up again and transported to the 12 o'clock position.In the process of dropping from the back sorting tool, the inversion guide gutter and posture control plate work together to automatically invert the top and back surfaces of the target part, so that it is dropped at the 6 o'clock position in the bowl.This dramatically increases the probability that the target part will be picked up with its top surface facing up when picked up at the suction point of the transport turntable, making it possible to realize even more efficient sorting.
[0020] The front / back sorting tool has a base end facing the discharge port that is connected to the inner wall of the bowl, and the rotary drive source has a tip end of its output shaft that protrudes toward the conveying surface wall of the conveying turntable and is rotatably supported by a bearing mounted in a bearing box integrated into the central end of the front / back sorting tool, and the front / back sorting tool is supported in a bridge-like manner between the inner wall of the bowl and the output shaft of the rotary drive source. According to the part supply device of this invention, the bearing box supports the tip end of the front / back sorting tool, the base end of which is supported on the inner wall of the bowl, and the support strength of the front / back sorting tool can be significantly increased without interfering with the rotational movement of the conveying turntable.In addition, the front / back sorting tool supports the bearing and bearing box that rotatably support the output shaft of the rotary drive source with sufficient strength, eliminating the need for strength parts that individually support each of the front / back sorting tool and the bearing box, reducing the number of parts and achieving significant weight and cost reduction. BEST MODE FOR CARRYING OUT THEINVENTION
[0021] The best or desirable mode for carrying out the present invention having the above-mentioned configuration will now be described. The bowl surrounds the outer periphery of the conveying turntable, enclosing it in a cylindrical shape capable of accommodating a plurality of target parts in a random orientation, and has the function of providing an outlet for sending out only the target parts that have passed through the front and back sorting tool and been selected. The bowl is cylindrical and capable of accommodating a plurality of the target parts, and is supported immovably in an inclined orientation perpendicular to the horizontal to the sliding angle at which the target parts slide down. The peripheral wall must have an outlet opening for sending out the target parts on the centrifugal side in the 2 o'clock to 4 o'clock direction when the conveying surface wall rotates clockwise, and in the 8 o'clock to 10 o'clock direction when the conveying surface wall rotates counterclockwise. More specifically, the bowl must be horizontally supported in a cylindrical shape capable of accommodating a plurality of the target parts, and be supported immovably in an inclined orientation perpendicular to the horizontal to the sliding angle at which the target parts slide down. In contrast, the bowl should be supported immovably in an inclined position perpendicular to the sliding angle of 30° to 60°, that is, in an inclined position of 120° to 150° from the horizontal. If the inclination angle is less than 120°, the bowl will approach a vertical position, and the difference in height from the 6 o'clock position to the 12 o'clock position on the conveying turntable will become too small, which may make it difficult to obtain sufficient potential energy required for sorting. On the other hand, if the inclination angle exceeds 150°, the bowl will approach a horizontal position, making it difficult for the target parts to gather at the 6 o'clock position on the conveying turntable, and they will be prone to overflowing from the upper opening of the bowl, which may result in a disadvantage that a sufficient storage volume cannot be secured and may reduce work efficiency. As will be shown in the examples described later, it is also desirable that the upper opening of the bowl serves as a supply port for the target parts and that it be fitted with an opening / closing lid, and that the opening / closing lid be made of a transparent material such as a transparent synthetic resin so as to make it easy to check the amount and state of the target parts contained and to check the sorting operation.
[0022] The conveying turntable has the function of converting a portion of its rotational drive energy into potential energy of the target parts and supplying the target parts from above towards the front / back sorting tool below. The conveying turntable must have suction points for suctioning the target parts at multiple points along the circumferential direction of a circular conveying surface wall that is inclined at an angle at which the target parts slide down, and a rotational drive source for rotating the conveying surface wall must be provided. The conveying surface wall must have its center coincident with the center of the cylindrical shape of the bowl and must be inclined at a sliding angle of 30° to 60°, preferably 45°, from the horizontal. If the inclination angle of the conveying surface wall is less than 30° from the horizontal, it is difficult to ensure that the target parts will slide down smoothly and quickly. Also, if the inclination angle of the conveying surface wall is more than 60° from the horizontal, the sliding speed of the target parts will be too high, and in either case there is a risk of deteriorating the sorting accuracy.
[0023] The conveying turntable has a smooth surface that does not hinder the smooth sliding of the target parts, and the centrifugal side of the diameter of the disk-shaped conveying wall has a circumferential length that is an integer multiple of the dimension of the diameter of the disk-shaped target part plus the interval, and permanent magnets are embedded flush with the conveying wall as attraction points at intervals equal to the dimension of the diameter of the target part plus the interval along the circumference of the centrifugal side of the conveying wall, each attraction point being replaced by a permanent magnet, suction pipes running vertically through the thickness of the conveying wall, the suction ports of each suction pipe being exposed flush on the surface of the conveying wall, and the base ends of each suction pipe are connected to the piping on the suction side of the air compressor.
[0024] The front and back sorting tool is designed to pick up target parts that are attracted to each suction point, guided in an arc as the conveying wall rotates, and rise to a position that is 12 o'clock from the center of the conveying turntable. The target parts are peeled off from the suction points in the order in which they are conveyed, and from among the target parts that lose their suction power and slide down, it selects only those whose back side is on the ground and whose top side is facing up, and sends them out from the delivery outlet, while guiding those whose top side is on the ground and whose back side is facing up so that they fall into the bowl. The tool must be installed immovably with a peeling plate in the range from the delivery outlet to the center of the conveying wall, and the peeling plate must be located at a position that is 6 o'clock in the direction of the suction point when it is aligned with the 12 o'clock direction of the center of the conveying wall, or at a position that is 6 o'clock in the direction of the conveying wall by a dimension that exceeds the diameter of the target part. The peeling plate should have a tip angle at any position between the centers of the walls, a central end extending from the center of the conveying surface wall to the tip angle, a peeling edge extending from the tip angle to the upstream end of the discharge outlet, and a sliding end extending from the center of the conveying surface wall at the central end to the downstream end of the discharge outlet, and the peeling plate should be provided with a coarse sorting area at an upper position near the tip angle, the coarse sorting edge having an edge thickness sufficiently larger than the radius of curvature of the cross section of the back surface outer edge of the target part and slightly smaller than the radius of curvature of the cross section of the top surface outer corner, and a fine sorting area at a lower position near the downstream end of the discharge outlet, the fine sorting area having a fine sorting edge having an edge thickness set to be the same as or very slightly larger than the radius of curvature of the cross section of the back surface outer edge of the target part and sufficiently smaller than the radius of curvature of the cross section of the top surface outer corner.
[0025] To show a more specific example of the front and back sorting tool, as shown in the examples described later, the tool is immovably disposed in the range from the delivery port to the center of the conveying wall, with a peeling plate having a separation angle of 45° to 15° with respect to the horizontal from the upstream rotation direction to the downstream rotation direction with respect to the conveying wall, and the tip angle of the peeling plate is either between a position that is 6 o'clock by a dimension exceeding the diameter of the target part from the position of the suction point when it is aligned with the 12 o'clock direction of the center of the conveying wall, or the center of the conveying wall, and further between a 12 o'clock line passing through the center of the conveying wall and a position that is 3 o'clock to 6 o'clock or 6 o'clock to 9 o'clock. the peeling plate has a peeling edge extending from the tip corner to the center of the conveying surface wall slightly toward the 12 o'clock direction from the upstream end of the conveying outlet, 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 conveying outlet, and the front and back sorting tool has a top rough sorting area closer to the tip corner within a range from the central end to the conveying outlet in either the 9 o'clock or 3 o'clock direction, and a bottom fine sorting area closer to the conveying outlet and closer to the 6 o'clock direction, A medium normal sorting zone is disposed between the coarse sorting zone and the fine sorting zone, and the coarse sorting zone is provided with a coarse sorting edge having an edge thickness sufficiently larger than the radius of curvature of the cross section of the outer periphery of the back surface of the target part and slightly smaller than the radius of curvature of the cross section of the outer periphery of the top surface, and facing the outlet, and a buffer coarse rail having a rail width sufficiently larger than the radius of curvature of the cross section of the outer periphery of the back surface of the target part and slightly smaller than the radius of curvature of the cross section of the outer periphery of the top surface, and extending from the upper surface of the peeling plate beyond the coarse sorting edge and having a gentle downward slope toward the outlet, and the normal sorting zone is provided with an edge thickness of a parallel sorting edge is provided facing the outlet, and the rail width is set to be greater than the radius of curvature of the cross section of the outer periphery of the back surface of the target part and smaller than the radius of curvature of the cross section of the outer periphery corner of the top surface of the target part, the rail width is set to be greater than the radius of curvature of the cross section of the outer periphery of the back surface of the target part and smaller than the radius of curvature of the cross section of the outer periphery corner of the top surface of the target part, the parallel sorting edge is provided from the upper surface of the peeling plate, the parallel sorting edge is provided, and the parallel sorting edge is provided facing the outlet, the parallel sorting edge is provided from the upper surface of the peeling plate, the parallel sorting edge is provided, and the parallel sorting edge is provided facing the outlet, the parallel sorting edge is providedIt is preferable to provide a fine selection edge facing the outlet, the radius of curvature of which is set sufficiently smaller than the radius of curvature of the cross section of the outer peripheral corner of the top surface, and a buffer narrow rail having a rail width set to be equal to or slightly larger than the radius of curvature of the cross section of the outer peripheral corner of the top surface of the target part, extending from the upper surface of the peeling plate beyond the fine selection edge toward the outlet, and having a downward slope even greater than that of the buffer regular rail.
[0026] If the angle of the peeling plate of the front and back sorting tool exceeds 45° from the horizontal, the target parts will slide down too quickly, which may make it difficult to perform sorting with high precision. If the angle is less than 15° from the horizontal, it will be difficult to achieve smooth and quick sliding of the target parts. In either case, it may be difficult to perform sorting with high precision. The reason why it is preferable that the tip angle of the peeling plate is disposed at a position between the position of the suction point when it is aligned with the 12 o'clock direction of the center of the conveying wall and the 6 o'clock direction by a dimension exceeding the diameter of the target part, and the center of the conveying wall, and further at a position that satisfies the condition that a 12 o'clock direction line passing through the center of the conveying wall intersects with a straight line inclined at 5° to 25° in the 12 o'clock direction from the center of either the 3 o'clock to 6 o'clock or 6 o'clock to 9 o'clock delivery opening and a straight line inclined at less than 5° in the 12 o'clock direction and a horizontal line, is that when the tip angle is disposed at a position where a 12 o'clock direction line passing through the center of the conveying wall intersects with a straight line inclined at less than 5° in the 12 o'clock direction and a horizontal line, the inclination of the peeling edge toward the delivery opening is small. If the tip angle becomes too large, there is a risk that the target part will not roll smoothly toward the discharge outlet even when it comes into contact with the peeling edge, but will fall in the opposite direction to the discharge outlet (upstream of the rotation of the conveying surface wall).Furthermore, if the tip angle is arranged at the intersection of a 12 o'clock line passing through the center of the conveying surface wall and a straight line inclined at more than 25° in the 12 o'clock direction with respect to the horizontal line, the inclination of the peeling edge toward the discharge outlet will be too large, and the target part that comes into contact with the peeling edge will not be able to accurately follow each of the sorting zones, from the coarse sorting zone to the fine sorting zone, and will fall rapidly toward the discharge outlet.In either case, there is a disadvantage that it becomes difficult to perform high-precision sorting efficiently.
[0027] As shown in the examples described later, the coarse sorting edge, the normal sorting edge and the fine sorting edge can all be the plate thickness portions (each edge thickness portion) facing the 12 o'clock direction of a plate-shaped member overlapped and joined to the top surface of the peel-off plate, or the plate thickness portions (each edge thickness portion) facing the 12 o'clock direction of a rod-shaped material with a rectangular cross-section overlapped and joined to the top surface of the peel-off plate. The buffer coarse rail, the normal buffer rail and the fine buffer rail can all be rod-shaped or pipe-shaped set to the respective rail widths, or the upper edge in the 12 o'clock direction of the plate-shaped part set to the respective rail widths can be cylindrical or polygonal tube-shaped, etc. As will be shown in the examples described later, the fine sorting area of the front and back sorting tool has a fine sorting edge that has multiple steps that descend in a stepped manner from the central end toward the send-out outlet, and the buffer thin rail has a rail width that is set to be very 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 top surface, and a final sorting rail with a gentler downward slope than the buffer coarse rail of the coarse sorting area is provided from the middle of the buffer regular rail toward the send-out outlet on the upper surface of the peel-off plate.
[0028] As shown in the embodiments described below, the part supply device of this invention is preferably provided with a multiple avoidance tool having an exclusion plate set to a length that is either slightly beyond the suction point of the conveying surface wall toward the center or that reaches the center of the conveying surface wall, and positioned at a distance slightly exceeding the thickness dimension of one of the target parts, on the inner wall of the bowl surrounding a sector-shaped area that is in the 12 o'clock direction from the 9 o'clock / 3 o'clock line passing through the center of the conveying surface wall of the conveying turntable, and that is upstream of the 12 o'clock line passing through the center of the conveying surface wall in the direction of rotation of the conveying turntable. In addition, as shown in the embodiment described later, the component supply device of the present invention can be provided with a peeling auxiliary tool having a guide plate set to a length that is either a length slightly longer than the suction point of the conveying surface wall from the inner peripheral wall of the bowl facing the front / back sorting tool in the 12 o'clock direction, or a length equivalent to one diameter of the target component, and the guide plate is positioned at a distance from the conveying surface wall that is shorter than the thickness dimension of one target component. Furthermore, the peeling auxiliary tool can be provided with a guide plate set to a length slightly longer than the suction point of the conveying surface wall from the inner peripheral wall of the bowl facing the front / back sorting tool in the 12 o'clock direction, or a length equivalent to one diameter of the target component, and the guide plate is positioned at a distance shorter than the thickness dimension of one target component from the conveying surface wall. The apparatus may be provided with an attitude conversion tool consisting of a reversing guide gutter extending in the rotational direction of the turntable and guiding the target parts sliding down with their top wall in contact with the peeling plate in the centrifugal direction from the center of the conveying surface wall and curving to guide the target parts so as to turn them over, and an attitude control plate provided on the inner peripheral wall of the bowl facing the centrifugal direction of the reversing guide gutter and interfering with the back wall of the target parts to land on the conveying surface wall of the conveying turntable.
[0029] As shown in the examples described later, the front / back sorting tool can be configured such that the base end facing the delivery port is connected to the inner peripheral wall of the bowl, the rotary drive source is provided at the bottom of the bowl, the tip of the output shaft thereof protruding toward the delivery surface wall of the delivery turntable is rotatably supported by a bearing installed in a bearing box integrated at the central end of the front / back sorting tool, and the front / back sorting tool is supported in a bridge-like manner between the inner peripheral wall facing the delivery port of the bowl and the output shaft of the rotary drive source. More specifically, the rotary drive source can be a gear motor with a reducer integrally provided therewith, a servomotor, or the like.
[0030] The target parts of this invention are fed into the part supply device of this invention, aligned in a front position, and sent to the next process; more specifically, they must be objects in which the radius of curvature of the cross section of the outer periphery of the circular back surface is set to be smaller than the radius of curvature of the cross section of the outer periphery of the top surface; even more specifically, they can be twist caps, lug caps, or screw caps.

[0033] In the example shown in Figures 1 to 15, a bowl 4 is supported immovably in an inclined attitude TA perpendicular (90°) to the sliding angle SA at which the target part TC slides with respect to the horizontal HZ, a conveying surface wall 20 inclined at the sliding angle SA is provided near the bottom 40 of the bowl 4, suction points 23, 23, ... are provided along the outer periphery of the conveying surface wall 20, a conveying turntable 2 provided with a rotary drive source 3 is provided, a delivery port 43 through which the target part TC can be delivered is opened in a peripheral wall 42 of the bowl 4, and a front / back sorting tool FS having a peeling plate 5 is fixedly provided in the range from the delivery port 43 to the center C of the conveying surface wall 2, and the peeling plate 5 shows a representative embodiment of a part supplying device of this invention, in which, in the range from the delivery outlet 43 to the center C of the conveying surface wall 2, there is a central end 52 at the center C of the conveying surface wall 20 and whose 12 o'clock end is formed as a tip angle 50, a peeling edge 51 extending from the tip angle 50 to the delivery outlet 43, and a sliding end 53 extending from the center C of the conveying surface wall 20 of the central end 52 to the delivery outlet 43, and the peeling plate 5 is provided with a coarse sorting area 6 having a coarse sorting edge 60 at the upper part near the tip angle 50, and a fine sorting area 8 having a fine sorting edge 80 at the lower part near the downstream end of the delivery outlet 43.
[0034] As shown in Figs. 17 to 19, the target parts TC to be aligned by the part supplying device 1 of the present invention are made of a magnetic material (for example, tin free steel, tinplate, magnetic stainless steel, etc.), and a short cylindrical peripheral wall PW hangs down from a top surface outer peripheral angle SE of the outer periphery of a disk-shaped top surface SF wall having a diameter TD of 43 mm to 83 mm toward the back surface BS. A plurality of lugs RG, RG, ... are screwed into a multiple thread screw provided on the outer peripheral wall of the opening of the target bottle and protrude in a centripetal direction from the back surface BS end of the peripheral wall PW. The radius of curvature RR of the cross section of the back surface outer peripheral edge BE is set to be smaller than the radius of curvature RF of the cross section of the top surface outer peripheral angle SE. If necessary, a clicker safety button (Clicker safety button) is provided in the center of the top surface SF wall. A twist off cap (hereinafter abbreviated) TC is provided with a twist off button (CB), and an annular elastic sealing membrane EF is attached to the area where the opening edge of the target bottle abuts on the back side BS, which is the inner wall surface of the top surface SF, and the center of gravity is located toward the center of the top surface SF.
[0035] As can be clearly understood from each of Figures 1 to 15, the part supplying device 1 of the present invention is a cylindrical device with a diameter of 500 mm and a peripheral depth of 300 mm, which is located behind an automatic capping device (not shown) to which the twist caps TC are supplied and at a position higher than the handling unit of the automatic capping device. The device is inclined in an inclined position TA perpendicular to the horizontal HZ at a sliding angle SA of 30° to 60° toward the handling unit of the automatic capping device, and more specifically, at an angle of 135° (SA: 45° + RA: 90°, the angle in Figure 2) perpendicular to the horizontal HZ. Bowl 4 is inclined at an angle of 0.5° (TA) and is supported immovably by support legs SL hanging down from its bottom 40. A disk-shaped conveying surface wall 20 is disposed concentrically C with cylindrical peripheral wall 42 of bowl 4 at a depth of 280 mm from an upper opening 41 of bowl 4 to inner peripheral wall 42 of bowl 4, with its outer peripheral end 21 in non-contact with inner peripheral wall 42 of bowl 4 via a very small gap. A volume capable of accommodating 200 twist caps TC with a diameter TD of large (Φ83 mm) or 400 twist caps TC with a diameter TD of small (Φ43 mm) is secured within bowl 4.
[0036] A gear motor 3 with an integrated reducer is connected as a rotational drive source 3 to the center of the outer wall 40 of the bottom 40 of the bowl 4, and its output shaft 30 passes through the bottom wall 40 of the bowl 4 in a freely rotatable state, and is connected and integrated in a penetrating manner to the center of the conveying surface wall 20 of the conveying turntable 2 and a flange 22 connected to the center of the lower wall of the conveying surface wall 20. Furthermore, the tip of the output shaft 30, which passes through the conveying turntable 2 and protrudes into the bowl 4, is rotatably supported by a ball bearing BL as a bearing mechanism BL mounted in a bearing box BB described later. The gear motor 3 receives input operations from a control panel (not shown) and drives the conveying turntable (conveying surface wall 20) 2 counterclockwise around the center C at a constant rotation speed decelerated to a speed suitable for sorting the top and back surfaces of the twist caps TC, and stops rotating when a stop operation is performed.
[0037] The conveying turntable 2 has a plurality of attraction points 23, 23, ..., which are formed by embedding permanent magnets 23, 23, ... for attracting the twist cap TC so that their top surfaces are exposed flush, at intervals VL equal to the outer diameter of the twist cap TC or at intervals VL of about 1.1 to 2 times the outer diameter of the twist cap TC, in a circumferential direction along the outer periphery slightly closer to the center C than the outer circumferential end 21 of the conveying surface wall 20 of the conveying turntable 2. A discharge opening 473 is opened in the peripheral wall 42 of the bowl 4, and the dimensions and shape of the discharge opening 473 are set so that the twist caps TC can be discharged one by one. In the range from the discharge opening 43 in the peripheral wall 42 of the bowl 4 to the bearing box BB at the center C of the conveying surface wall 20, a front and back sorting tool FS is fixedly arranged having a peeling plate 5 that forms a departure angle WA of 45° to 15°, more specifically 22.5°, with respect to the horizontal HZ from the upstream to the downstream of the rotational drive direction RD shown by the dotted line arrow in Figure 1 with respect to the conveying surface wall 20.
[0038] The peeling plate 5 of the front and back sorting tool FS is located between a position in the 6 o'clock direction from the position of the suction point 23 when it is aligned with the 12 o'clock direction of the center C of the conveying surface wall 20 by a dimension slightly exceeding the diameter TD of the twist cap TC and the center C of the conveying surface wall 20, and has a tip angle 50 arranged at a position where a 12 o'clock direction line passing through the center C of the conveying surface wall 20 intersects with a straight line inclined at an angle of 5° to 25°, preferably 15°, in the 12 o'clock direction from the upstream end of the delivery opening 43 in the 9 o'clock direction to the horizontal, and the tip angle 50 is located at a position between the upstream end 44 of the delivery opening 43 and the tip angle 50. The peeling plate 5 has a peeling edge 51 extending slightly (for example, about 1 / 2 the diameter TD of the twist cap TC, i.e., about the radius) toward the 12 o'clock direction (upstream), a central end 52 extending from the tip angle 50 to the center C of the conveying surface wall 20, and a sliding end 53 extending from the center C of the conveying surface wall 20 of the central end 52 to the downstream end 45 of the delivery opening 43, and the upper surface 54 of the peeling plate 5 is polished (mirror-finished) to a smooth surface so as to avoid unnecessary friction with the twist cap TC, and the back edge of the peeling edge 51 is cut into a blade-like cross-sectional shape so as not to interfere with the conveying surface wall 20, forming an acute-angled edge.
[0039] The 9 o'clock base end of the peeling plate 5 is connected to and supported by the inner wall 42 of the bowl 4 which forms the lower edge of the delivery outlet 43, and the central end 52 of the peeling plate 5 facing the center C of the conveying surface wall 20 is integrally connected to the bearing box BB, and the peeling plate 5 supports the output shaft 30 of the gear motor 3 and the ball bearing BL which supports it via the bearing box BB. The lower end of the central end 52 is slightly inclined from its tip corner 50 to near the 3 o'clock corner of the bearing box BB, and a blocking wall portion 55 is provided which closes the gap between the conveying surface wall 20 and the upper surface 54 of the peeling plate 5 in a non-contact state.
[0040] If the arrangement of the tip angle 50 is expressed in a different way from that described above, it can be said that the tip angle 50 is located either in a sectorial range that is upstream of a 12 o'clock line passing through the center C of the conveying surface wall 20 in the rotation direction RD of the conveying surface wall 20, and further in the 12 o'clock direction from a 9 o'clock / 3 o'clock line passing through the center C of the conveying surface wall 20, at a position that is centripetal (closer to the center C) at a distance that exceeds the diameter TD of the twist cap TC from the inner circumferential wall 42 of the bowl 4, or at a position that is centripetal (closer to the center C) at a distance within twice the diameter TD of the twist cap TC.
[0041] If the support structure of the front and back sorting tool FS is expressed in a different way from that described above, the base end of the front and back sorting tool FS facing the discharge outlet 43 is connected to the inner wall 42 of the bowl 4, and the tip of the output shaft 30 of the gear motor 3 protruding toward the conveying surface wall 20 of the conveying turntable 2 is rotatably supported by a ball bearing BL mounted in a bearing box BB integrated into the central end 52 of the front and back sorting tool FS, and the front and back sorting tool FS is supported at both ends in a spanning manner between the inner wall 42 of the bowl 4 and the output shaft 30 of the gear motor 3.
[0042] The peeling plate 5 of the front and back sorting tool FS is provided with a top coarse sorting area 6 near the tip corner 52, a bottom fine sorting area 8 near the outlet 4 and in the 6 o'clock direction, and a middle normal sorting area 7 between the coarse sorting area 6 and the fine sorting area 8, within a range from the central end 52 to the outlet 43 in the 3 o'clock direction. The coarse sorting area 6 has an edge thickness of 3 mm to 1.5 mm, which is sufficiently larger than the radius of curvature RR (about 0.9 mm) of the cross section of the back outer periphery BE of the twist cap TC and slightly smaller than the radius of curvature RF (about 4.6 mm) of the cross section of the top outer periphery angle SE of the twist cap TC, and is preferably 0.05 to 0.15 mm. A rough sorting edge 60 is provided which is set to 2 mm and faces the discharge outlet 43, and a round bar-shaped buffer rough rail 61 is provided which has a rail width set to Φ4 mm to Φ1.5 mm, preferably Φ3 mm, which is sufficiently larger than the cross-sectional radius of curvature RR (approximately 0.9 mm) of the back outer peripheral edge BE of the twist cap TC and slightly smaller than the cross-sectional radius of curvature RF (approximately 4.6 mm) of the top surface outer peripheral angle SE of the twist cap TC, and which extends from the upper surface 54 of the peeling plate 5 beyond the rough sorting edge 60 and has a gentle downward slope (for example, 5° to 20°, preferably 12° from the horizontal) toward the discharge outlet 43.
[0043] The sorting area 7 includes a sorting edge 70 having an edge thickness of 3 mm to 1.5 mm, preferably 2 mm, which is greater than the radius of curvature RR (approximately 0.9 mm) of the cross section of the back outer periphery BE of the twist cap TC and smaller than the radius of curvature RF (approximately 4.6 mm) of the cross section of the top outer periphery angle SF of the twist cap TC, and a rail width of Φ4 mm to Φ1.5 mm, preferably Φ3 mm, which is greater than the radius of curvature RR (approximately 0.9 mm) of the cross section of the back outer periphery BE of the twist cap TC and smaller than the radius of curvature RF (approximately 4.6 mm) of the cross section of the top outer periphery angle SE of the twist cap TC. A buffer parallel rail 71 is provided, which extends from the upper surface 54 of the peeling plate 5, beyond the parallel sorting edge 70, toward the discharge outlet 43, and has a downward slope sufficiently greater than that of the buffer coarse rail 61 (for example, 8° to 25°, preferably 17° from the horizontal), and the coarse sorting edge 60 and the parallel sorting edge 70 consist of a single 2 mm thick plate P1 which has a stepped planar shape from the coarse sorting edge 60 to the parallel sorting edge 70 toward the discharge outlet 43, and is superimposed on the upper surface 54 of the peeling plate 5 and joined together, ensuring a sufficient joining area.
[0044] The fine sorting area 8 has an edge thickness set to 2 mm to 0.9 mm, preferably 1 mm, which is the same as or slightly larger than the radius of curvature RR (approximately 0.9 mm) of the cross section of the back outer edge BE of the twist cap TC, and is sufficiently smaller than the radius of curvature RF (approximately 4.6 mm) of the cross section of the top outer peripheral angle SF of the twist cap TC. The fine sorting edge 80 facing the delivery port 43 and the rail width are set to Φ4 mm to Φ1.5 mm, preferably Φ3 mm, which is the same as or slightly larger than the radius of curvature RR (approximately 0.9 mm) of the cross section of the back outer peripheral edge SE of the twist cap TC, and is sufficiently smaller than the radius of curvature RF (approximately 4.6 mm) of the cross section of the top outer peripheral angle RF of the twist cap TC. A buffer narrow rail 81 is provided extending from the upper surface 54 of the peel-off plate 5, beyond the fine sorting edge 80, toward the discharge outlet 43, and has an even greater downward slope than the buffer parallel rail 71 (for example, 9° to 26°, preferably 20° from the horizontal). The fine sorting edge 80 has a plurality of steps which descend in a stepped manner from the central end 52 toward the discharge outlet 43. The fine sorting edge 80 is arranged in the 6 o'clock direction from the plate P1, and consists of a single plate P2 which is 1 mm thick and has a stepped planar shape toward the discharge outlet 43.

[0046] As shown in Figures 1, 3 and 14, a multiple avoidance tool MA is provided at a position, for example at approximately 1:30 on the inner peripheral wall 42 of the bowl 4 which is closer to 12 o'clock than the 3 o'clock line passing through the center C of the conveying surface wall 20 of the conveying turntable 2 and which surrounds a sector-shaped range which is upstream of the 12 o'clock line passing through the center C of the conveying surface wall 20 in the rotation direction RD of the conveying turntable 2. The multiple avoidance tool MA has a length which is set to either a length which slightly exceeds the suction points 23, 23, ... of the conveying surface wall 20 toward the center C or a length which reaches the center C of the conveying surface wall 20, and whose tip on the center C side is inclined downstream in the rotational drive direction RD, and is located at a distance DC from the conveying surface wall 20 toward the upper end opening 41 of the bowl 4 at a distance DC which is slightly greater than the thickness dimension TT of one twist cap TC (for example, 10 mm) (for example, 12 mm).
[0047] As shown in Figures 1, 3 and 15, a peeling auxiliary tool PA is provided on the inner wall 42 of the bowl 4 facing the front and back sorting tool FS in the 12 o'clock direction, and has a length that is either a length that extends from the inner wall 42 of the bowl 4 slightly beyond the suction points 23, 23 of the conveying surface wall 20 toward the center C of the conveying surface wall 20, or a length that is the diameter TD of one twist cap TC, and has a guide plate GP with its tip inclined toward the downstream side in the rotational drive direction RD, and is located at a distance GA (e.g., 3 mm) shorter than the thickness dimension TT of one twist cap TC (e.g., 10 mm) from the conveying surface wall 20 toward the upper end opening 41 of the bowl 4.
[0048] As shown in Figures 1, 6, 7, 10 and 11, a posture conversion tool PC is provided which extends from the sliding end 53 of the peeling plate 5 of the front and back sorting tool FS in the rotation direction RD of the conveying turntable 2, and guides the twist caps TC sliding down with their top wall SF in contact with the peeling plate 5 in the centrifugal direction from the center C of the conveying surface wall 20, and is curved toward the upper end opening 41 of the bowl 4 so as to guide the twist caps TC to be turned upside down, and a posture control plate AB is provided on the inner wall 42 of the bowl 4 facing the reversing guide gutter VG at the 6 o'clock direction, and cushions the twist caps TC falling from the reversing guide gutter VG while interfering with the back wall BS of the twist cap TC to land on the conveying surface wall 20 of the conveying turntable 2.
[0049] As shown in Figures 1 to 5, 9, 10 and 12, on the outer side of the discharge outlet 43 of the outer wall 42 of the bowl 4, a straight sliding guide rail GL with an inclination angle the same as the release angle WA (22.5° from the horizontal) of the peeling plate 5 of the front and back sorting tool FS is connected via a direction changing path LD in the inclination direction of the bowl 4 toward the handling section of the automatic lid application device (not shown). After sorting, the twist caps TC, TC, ... facing upward on the top surface SF are changed direction by their own weight as they pass through the direction changing path LD, and descend and move along the sliding guide rail GL to the handling section (not shown).
[0050] As shown in Figs. 2 and 5, an opening / closing lid 46 is attached to the upper opening 41 of the bowl 4. The opening / closing lid 46 is made of transparent resin and covers the upper opening 41 of the bowl 4 (peripheral wall 42) from a horizontal line below the center C of the upper opening 41 of the bowl 4 to the 12 o'clock position of the conveying surface wall 20 of the conveying turntable 2. The opening / closing lid 46 has an upper handle TH on the top surface corresponding to the center C of the upper opening 41, and a main arcuate shape with a fitting sleeve SV provided on the peripheral edge. The surface cover portion 47 is attached in a fitting manner, and in the arcuate surface area on the 6 o'clock side of the upper end opening 41 which is the remaining area of the main arcuate surface cover portion 47, an arcuate door portion 48 having a shape corresponding to the same area, an opening / closing handle HD is provided on its top wall, and an engaging sleeve SV is provided on its peripheral edge is arranged, and the upper end of the arcuate door portion 48 is connected to the lower end of the main arcuate surface cover portion 47 via hinges 49, 49 so as to be able to be opened and closed freely, as shown by the dotted line in Figures 1 and 5.
[0051] As shown in FIG. 16, in the case of the component supplying device 1 of this invention in which the conveying turntable 2 is driven to rotate in a clockwise direction RD, it is preferable that the structures and arrangements of the conveying turntable 2, front / back sorting tool FS, multiple avoidance tool MA, peeling assist tool PA, posture changing tool PC, direction changing path LD and sliding guide rail GL shown in FIG. 1 are inverted left to right.
[0052] (Actions and Effects of Example 1) In the part supply device 1 of the present invention having the above-mentioned configuration, as shown in Figs. 2 and 9, the arc-shaped door portion 48 of the opening / closing lid 46 is opened, and for example, about 300 twist caps TC, TC, ... are put into the bowl 4. Then, the arc-shaped door portion 48 is closed and a start operation is performed via a control panel (not shown). The gear motor 3 slowly rotates the conveying turntable 2 counterclockwise RD, and the twist caps TC, TC, ... that have been accumulated in various positions in the bowl 4 on the 6 o'clock side of the conveying surface wall 20 of the conveying turntable 2 are rotated in the counterclockwise direction RD. The twist caps TC are adsorbed to each of the suction points 23, 23, ... on the conveying surface wall 20 and raised to the 3 o'clock and 2 o'clock positions along the outer circumferential edge of the conveying surface wall 20. As shown in Figures 9 and 14, when the twist caps TC pass through the exclusion plate EX of the multiple avoidance tool MA, the upper twist caps TC overlapping the twist caps TC come into contact with the exclusion plate EX and drop in the 6 o'clock direction, and only one twist cap TC that is directly in contact with and adsorbed to the conveying surface wall 20 passes under the exclusion plate EX and moves in the 12 o'clock direction, thereby being given potential energy.
[0053] As shown in Figs. 10 and 15, when the twist cap TC reaches beyond the 12 o'clock position of the conveying surface wall 20 and comes into contact with the guide plate GP of the peeling auxiliary tool PA, it is blocked and disengages from the suction point 23 of the conveying surface wall 20, and the potential energy is released. As the twist cap TC slides down, it rides on the peeling edge 51 of the peeling plate 5 of the front and back sorting tool FS. As shown in Figs. 10 and 11, when the top surface SF of the twist cap TC is in contact with the peeling plate 5, the top surface outer circumferential angle SE of the twist cap TC first engages with the buffer rough rail 61 of the rough sorting area 6. If the roller is engaged with the rough sorting edge 60, it will roll while engaging with the buffering rough rail 61, and if it is not engaged, it will slide down toward the sliding end 53. If it is engaged, it will roll toward the parallel sorting area 7 while engaging with the rough sorting edge 60. If it is engaged, it will roll toward the parallel sorting area 7 while engaging with the buffering parallel rail 71 of the parallel sorting area 7. If it is not engaged, it will slide down toward the sliding end 53. If it is engaged, it will engage with the parallel sorting edge 70. If it is not engaged, it will slide down toward the sliding end 53. If it is engaged, it will roll toward the parallel sorting edge 70. The fine sorting edge 80 engages with the twist cap TC and rolls toward the fine sorting area 8, engages with the buffer narrow rail 81 of the fine sorting area 8, and if not latched, slides down toward the sliding end 53. If the fine sorting edge 80 engages with the final sorting rail 82, and if not latched, slides down toward the sliding end 53. If the fine sorting edge 80 engages with the final sorting rail 82, the fine sorting edge 80 will almost certainly not engage with the outer peripheral corner SE of the top surface of the twist cap TC and will slide down toward the sliding end 53. The twist cap TC that has slid down to the sliding end 53 is thrown upside down along the gutter-shaped curved shape of the inversion guide gutter VG of the attitude changing tool PC, as shown by the dotted line arrow in Figure 10 and in Figure 11, and lands in a position where its back surface BS is grounded near the 6 o'clock position of the conveying surface wall 20 while coming into contact with the attitude control plate AB waiting at its destination.The twist cap TC, with its back surface BS grounded to the conveying surface wall 20 in this manner, is again adsorbed to the suction point 23 and transported counterclockwise toward the 12 o'clock direction. In this way, the twist cap TC, whose top surface SF is grounded to the peeling plate 5, slides down the rough sorting area 6, the normal sorting area 7 and the fine sorting area 8, in the order of rolling like alternating smooth slopes and steps, and the potential energy is gradually released, so that the impact force when it falls is greatly reduced, deformation and damage can be more reliably prevented, and quietness is significantly improved.
[0054] 12 and 13, the twist cap TC, which has been moved in the 12 o'clock direction of the conveying surface wall 20 and has been given potential energy, passes the 12 o'clock position of the conveying surface wall 20 and comes into contact with the guide plate GP of the peeling auxiliary tool PA and is blocked. The twist cap TC is released from the suction point 23 of the conveying surface wall 20, and the potential energy is released. When the twist cap TC slides down, it rides up on the peeling edge 51 of the peeling plate 5 of the front and back sorting tool FS. If the twist cap TC has its back surface BS in contact with the peeling plate 5, the back surface outer circumferential corner BE of the twist cap TC is first hooked onto the buffer coarse rail 61 of the rough sorting area 6, and rolls while engaging with the buffer coarse rail 61, and then hits the rough sorting edge 60. The twist cap TC is engaged with the sliding rail GL, rolls toward the normal sorting area 7, rolls while engaging with the buffer normal rail 71 of the normal sorting area 7, engages with the normal sorting edge 70, rolls toward the fine sorting area 8, rolls while engaging with the buffer fine rail 81 of the fine sorting area 8, rolls toward the fine sorting edge 80 while engaging with the final sorting rail 82, rolls along the fine sorting edge 80, passes through the delivery outlet 43, and the twist cap TC with its top surface SF facing upward is delivered to the upper end of the sliding guide rail GL through the direction change path LD, and the twist cap TC is further guided by its own weight along the sliding guide rail GL and automatically supplied to the handling section of the automatic lid opening device (not shown) below.
[0055] Also, as shown in Figure 12, when the sliding guide rail GL is filled with twist caps TC, TC, ..., a sensor (not shown) arranged at the upper end of the sliding guide rail GL detects this and automatically stops the rotational drive of the gear motor 3, and when the sensor detects a decrease in the twist cap TC of the sliding guide rail GL, the gear motor 3 can be controlled to automatically resume the rotational drive.
[0056] (Conclusion) As described, the parts supplying device of the present invention is capable of achieving all of the intended objects through its novel configuration, and is easy to manufacture and is significantly simpler, smaller, lighter and less expensive than conventional parts supplying technologies, making it far more economical. In addition, it does not generate vibration or noise, and does not damage the target parts, and can sort more accurately and quickly. Therefore, it is also effective in the packaging process of products such as food that require a hygienic environment. It is expected that it will be highly regarded not only in the food manufacturing and food processing industries, but also in various other packaging industries besides food, and will be used and spread widely.
