Description

Technical Field

[0001] The present invention relates to an arrangement supply device for arranging and supplying small articles, i.e., arrangement objects, such as tablets, in a row. Background Art

[0002] The arrangement supply device is connected to, for example, an inspection device, a printing device, a packaging device, etc., and is configured to adjust the posture of the inspection objects, printing objects, and packaging objects (arrangement objects) supplied to these devices, arrange them in a row, and then transport them to the next process (outside). In addition, as the arrangement objects, electronic components such as tablets, capsules, chip capacitors, candies and other confectionery, washers, buttons and other relatively small items (small items) are exemplified.

[0003] In the prior art, as the arrangement supply device, there is a device disclosed in Japanese Patent Publication No. 2005-219844 (hereinafter referred to as Patent Document 1). As described in the publication, the arrangement supply device is configured to include a turntable, a first guide portion, a second guide portion, a third guide portion, and an ejection mechanism.

[0004] The turntable is arranged in a freely horizontally rotatable manner, and the array objects supplied to the upper surface are conveyed along the rotation direction thereof. The first guide portion is disposed above the turntable, and guides the supplied array objects to the outer periphery of the turntable. In addition, the second guide portion is an arc-shaped guide portion, and is also disposed above the turntable and closer to the outer periphery of the turntable than the first guide portion, and the array objects guided by the first guide portion are arranged while being guided along the inner side surface of the arc from the guide start end to the guide end end.

[0005] In addition, the third guide part has: a first guide member, one end of which is connected to the guide terminal of the second guide member, and the other end of which is extended to the outside of the turntable; and a second guide member, which is arranged opposite to the first guide member at a distance, and the third guide member introduces a row of arrangement objects arranged by sliding contact with the inner side surface of the second guide member into between the first guide member and the second guide member, and guides them to the outside of the turntable. In addition, the exclusion mechanism is arranged near the introduction part of the third guide member, and is configured to return the arrangement objects other than the arrangement objects transported by sliding contact with the inner side surface of the second guide member to the inner side of the turntable. In addition, on the second guide member and / or the first guide member near the arrangement of the exclusion mechanism, a suction space opened on the inner side surface thereof is formed, and a suction mechanism is provided, which is connected to the suction space and sucks in external air through the opening.

[0006] According to the arrangement supply device, the arrangement objects are appropriately supplied to the horizontally rotating turntable. Then, the supplied arrangement objects are transported along the rotation direction of the turntable by the rotation of the turntable, and after being guided by the first guide part and moving toward the outer periphery of the turntable, they are arranged in a substantially single row along the inner side surface of the guide surface of the second guide part.

[0007] The arranged objects move along the path between the first guide member and the second guide member that reaches the third guide member via the guide terminal of the second guide member, but during the movement, the objects in the outermost row that are transported by sliding contact with the inner side surface of the second guide member are attracted by the suction mechanism through the opening formed on the inner side surface of the second guide member and / or the first guide member, and move in a state of being attracted by the inner side surface. In addition, the objects other than the outermost row are returned to the inner side (i.e., the center side) of the turntable by the exclusion mechanism.

[0008] Then, the objects to be arranged in a row by the second guide portion are introduced into between the first guide member and the second guide member from the introduction portion of the third guide portion, and are transported to the outside of the turntable.

[0009] Prior art literature

[0010] Patent Literature

[0011] Patent Document 1: Japanese Patent Application Publication No. 2005-219844 Summary of the invention

[0012] In addition, as described above, as the objects to be arranged, tablets, capsules, chip capacitors, etc. are exemplified. Taking tablets as an example, tablets of new shapes have been launched in recent years, for example, Figure 7 As shown, a tablet having an oblong planar shape, an elliptical front shape, a substantially circular cross-sectional shape, and a band-shaped flat surface on the outer periphery (hereinafter referred to as an "irregular-shaped tablet") is marketed.

[0013] In the field of tablets, in recent years, information such as product numbers are printed on the tablet surfaces using a printing device, and as a device for printing, a system in which the arrangement supply device is connected to the printing device is proposed. In addition, in the case of the arrangement supply device, the tablets as the arrangement objects need to be arranged in a state where the printed surface printed by the printing device is, for example, the upper surface.

[0014] However, in the arrangement and supply device of the prior art, in the case of the above-mentioned irregular-shaped tablets, there is a problem that they cannot be arranged in the same state in such a way that the specified printing surface becomes the upper surface. Therefore, in the subsequent printing device, there is a problem that tablets cannot be printed on the specified printing surface.

[0015] use Figure 8 and Fig. 9 According to the arrangement supply device of the prior art, the arrangement object K is conveyed along the inner side surface of the second guide portion by the rotation of the turntable 101, and is roughly arranged in a row with its long axis along the conveying direction. Figure 8 As shown, the liquid is guided between the first guide member 103 and the second guide member 104 of the third guide portion 102 and transported to the outside of the turntable 101 .

[0016] At this time, when the arrangement object K is the above-mentioned irregular-shaped tablet K, when the irregular-shaped tablet K slides in contact with the second guide member 104, it is subjected to a force acting in the rotation direction of the turntable 101 by friction with the turntable 101, such as Fig. 9 As shown, the strip-shaped tablet K is rotated 90° about its long axis to be in a position where the strip-shaped plane is in sliding contact with the turntable 101. Since this position is relatively stable, the irregular-shaped tablet K is conveyed to the outside of the turntable 101 while maintaining this position.

[0017] In addition, the cross-sectional shape of the irregularly shaped tablet is roughly circular, and its static posture itself is unstable. Therefore, when the irregularly shaped tablet is arranged in a row along the second guide portion, it is difficult to transport it along the second guide portion. At this time, there is a problem that the tablet cannot be smoothly introduced between the first guide component and the second guide component of the third guide portion.

[0018] The present invention has been completed in view of the above actual situation, and its purpose is to provide an arrangement and supply device, which can reliably arrange tablets in a row in a prescribed posture and supply them to the outside even if the tablets have an oblong plane shape, an elliptical front shape, a roughly circular cross-sectional shape, and an unstable static posture with a band-shaped plane on the outer periphery.

[0019] Means of solving the problem

[0020] The present invention for solving the above technical problems is an arrangement supply device, which has a turntable, an outward guide portion, an outer peripheral guide portion and a discharge guide portion, wherein:

[0021] The turntable is arranged in a freely horizontally rotatable manner to convey the arrangement objects supplied to the upper surface in the rotation direction;

[0022] The outward guide portion is disposed above the turntable and guides the array objects supplied to the turntable toward the outer periphery of the turntable.

[0023] The outer peripheral guide portion is also arranged above the turntable and is arranged at a position closer to the outer peripheral side of the turntable than the outward guide portion. The outer peripheral guide portion guides the arrayed objects guided by the outward guide portion along the guide surface which is the inner side surface of the arc from the guide starting end to the guide terminal end;

[0024] The discharge guide part is also arranged above the turntable, and has a first guide component and a second guide component, wherein one end of the first guide component is connected to the guide terminal end of the peripheral guide part, and the other end is extended to the outside of the turntable; the second guide component is arranged opposite to the first guide component with a gap, and the discharge guide part guides a row of arranged objects arranged in sliding contact with the guide surface of the peripheral guide part between the first guide component and the second guide component, and guides them to the outside of the turntable by using the mutually facing surfaces of the first guide component and the second guide component as guide surfaces,

[0025] The discharge guide portion is constructed such that a third guide portion is provided between the first guide portion and the second guide portion, and the lower surface of the third guide portion is an inclined surface inclined upward toward the first guide portion. The discharge guide portion introduces the arrangement object between the lower surface of the third guide portion and the guide surface of the first guide portion, and guides it toward the outside of the turntable.

[0026] According to the arrangement and supply device of this mode (first mode), the turntable rotates horizontally in the direction from its guide starting end toward the guide terminal end along the peripheral guide portion, and the arrangement object is appropriately supplied to the turntable rotating in this way. The supplied arrangement object is transported along its rotation direction by the rotation of the turntable, and after being guided by the outer guide portion and moving toward the outer periphery of the turntable, it becomes a state of being roughly arranged in a row along the inner side surface (inner peripheral surface) of the guide surface of the peripheral guide portion. At this time, in the case of the above-mentioned tablets with an oblong plane shape, an elliptical front shape, and a roughly circular cross-sectional shape (hereinafter referred to as "irregular-shaped tablets"), although its static posture is unstable, it is arranged in a state with the long axis along the conveying direction and the two faces with large curvature facing the upper and lower sides.

[0027] The arranged objects are guided between the lower surface of the third guide member of the discharge guide and the guide surface of the first guide member through the guide terminal of the outer peripheral guide, and then transported to the outside of the turntable. At this time, the lower surface of the third guide member becomes an upward inclined surface facing the first guide member, so even if the objects to be arranged are irregular tablets as described above, the irregular tablets are prevented from rotating around their long axis by sliding contact between their upper surfaces and the lower surface of the third guide member, and are transported to the outside of the system while keeping the two surfaces with large curvatures facing the upper and lower sides.

[0028] Thus, according to the arrangement and supply device, even the above-mentioned irregular-shaped tablets can be arranged in a row with the two surfaces with large curvatures facing the upper and lower sides, and can be supplied to the outside of the system while maintaining the arrangement state.

[0029] In the arrangement supply device of the first mode described above, preferably, the turntable has a stepped shape formed by a thick-walled portion on a center side and a thin-walled portion on a peripheral side, and the interval between the outer peripheral edge of the thick-walled portion and the guide surface of the peripheral guide portion has an interval capable of embedding one of the arrangement objects.

[0030] According to the arrangement supply device of this mode (second mode), the arrangement object moved toward the outer periphery of the turntable by the guidance of the outward guide portion is embedded in the thin wall portion between the guide surface of the outer periphery guide portion and the thick wall portion of the turntable, and in this state is conveyed to the guide terminal along the guide surface of the outer periphery guide portion. Therefore, even if the arrangement object is the irregular-shaped tablet whose static posture is unstable as described above, it can be conveyed to the guide terminal in a stable posture.

[0031] In addition, in the arrangement supply device of the second mode, it is preferred that a circular arc chamfered portion is formed at the outer peripheral corner of the thick wall portion of the turntable. When the outer peripheral corner of the thick wall portion is sharp, there is a possibility that the arrangement object will be damaged when it contacts the outer peripheral corner, but as in this mode (third mode), by forming a circular arc chamfered portion at the outer peripheral corner, such damage can be prevented.

[0032] In addition, in the arrangement supply device of the first to third aspects, it is preferred that a nozzle is further provided, the nozzle being arranged at a position closer to the center side of the turntable than the peripheral guide portion, and discharging airflow toward the guide surface of the peripheral guide portion. According to the arrangement supply device of this aspect (fourth aspect), the arrangement object can be moved toward the guide surface of the peripheral guide portion by the airflow discharged from the nozzle, and thus the arrangement object can be reliably transported to the guide terminal along the guide surface of the peripheral guide portion.

[0033] In addition, in the arrangement and supply devices of the first to fourth modes, it is preferred that the guide surface of the peripheral guide portion is composed of two surfaces continuously formed upward, namely, a vertical surface and an inclined surface, wherein the vertical surface is perpendicular to the turntable; and the inclined surface is inclined upward toward the center side of the turntable. According to the arrangement and supply device of this mode (fifth mode), the arrangement object is guided in a state of abutting against the vertical surface and the inclined surface of the peripheral guide portion, and is therefore conveyed in a state in which its posture is stable. In particular, even when the arrangement object is the irregular tablet, it is prevented from rotating around its long axis by abutting against the inclined surface, and the irregular tablet is conveyed in a stable posture with the two surfaces with large curvatures facing the up and down directions.

[0034] Effects of the Invention

[0035] As described above, according to the arrangement and supply device involved in the present invention, the lower surface of the third guide member with which the arrangement object slides becomes an upward inclined surface toward the first guide member. Therefore, even if it is an irregular-shaped tablet as mentioned above, it is possible to suppress rotation around its long axis. As a result, it can be transported outside the system while keeping the two surfaces with large curvatures facing the upper and lower sides. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Next, refer to the attached Figure 1 The specific implementation methods of the present invention are described below. Figure 1 As shown, the arrangement supply device 1 of this example is composed of: a turntable 2, which is arranged in a freely horizontally rotatable manner; an inward guide 3, an outward guide 7, an outer peripheral guide 8, two air exhaust nozzles 13, 14 and an exhaust guide 15 arranged above the turntable 2. In addition, the arrangement object in this example is Figure 7The irregularly shaped tablet K is shown.

[0046] The turntable 2 is supported by a rotation drive mechanism (not shown) in a freely horizontally rotatable manner, and is driven by the rotation drive mechanism (not shown) to rotate at a constant speed in the direction of arrow D. Figure 4 and Figure 5 As shown in FIG. 1 , a step is formed on the upper surface of the turntable 2, which is a step-like shape with a thick wall portion 2a at the center and a thin wall portion 2b at the periphery. Figure 5 As shown, an arc-shaped chamfered portion 2c is formed at the outer corner of the thick portion 2a. In addition, the thick portion 2a and the thin portion 2b of the turntable 2 of this example are formed integrally, the thin portion 2b is formed by cutting, and the arc-shaped chamfered portion 2c is formed.

[0047] Above the turntable 2, a supply port 20 of a storage device (e.g., a hopper, etc.) for storing a plurality of arrangement objects K is provided. The arrangement objects K are supplied to the turntable 2 from the supply port 20, and the arrangement objects K are transported in the direction of arrow D by the rotation of the turntable 2.

[0048] The inward guide portion 3 is a guide portion for guiding the arrangement object K supplied from the supply port 20 toward the center side of the turntable 2, and is composed of three guide portions, namely a first inward guide portion 4, a second inward guide portion 5 and a third inward guide portion 6, which are arranged in sequence toward the rotation direction of the turntable 2 (direction of arrow D).

[0049] The first inward guide portion 4 is arranged at a position closer to the outer circumference of the turntable 2 than the supply port 20, and one end thereof is located at a position closer to the upstream side than the supply port 20, and the other end thereof is located at a position closer to the downstream side in the rotation direction (arrow D direction) of the turntable 2. In addition, the second inward guide portion 5 is extended from the other end of the first inward guide portion 4, and the end portion at the downstream side is located closer to the center side of the turntable 2 than the other end of the first inward guide portion 4. In addition, the end portion at the upstream side of the third inward guide portion 6 is located closer to the outer circumference of the turntable 2 than the downstream end portion of the second inward guide portion 5, and the end portion at the downstream side is located closer to the center side of the turntable 2 than the downstream end portion of the second inward guide portion 5.

[0050] Furthermore, the first inward guide 4, the second inward guide 5 and the third inward guide 6 are arranged above the thick wall portion 2a of the turntable 2 at intervals through which the irregular-shaped tablets K cannot pass, and the center side surfaces of the turntable 2 serve as guide surfaces.

[0051] The outward guide portion 7 is arranged in such a manner that the end portion on the upstream side is located closer to the center of the turntable 2 than the end portion on the downstream side of the third inward guide portion 6, and the end portion on the downstream side is located at the outer peripheral edge of the thick wall portion 2a of the turntable 2. In addition, the outward guide portion 7 is also arranged above the thick wall portion 2a of the turntable 2 at a gap through which the irregular-shaped tablet K cannot pass, and is curved in such a manner as to form an arc-shaped convex portion toward the outer peripheral side of the turntable 2, and the surface on the outer peripheral side serves as a guide surface.

[0052] The outer peripheral guide 8 is composed of three guides, a first outer peripheral guide 9, a second outer peripheral guide 10, and a third outer peripheral guide 11, which are arranged in sequence in the rotation direction (arrow D direction) of the turntable 2 at a gap through which the irregular-shaped tablets K cannot pass. The surfaces of the first outer peripheral guide 9, the second outer peripheral guide 10, and the third outer peripheral guide 11 on the center side of the turntable 2 are continuous arc-shaped vertical guide surfaces 9a, 10a, and 11a, and each guide surface 9a, 10a, and 11a has a gap between the outer peripheral edge of the thick wall portion 2a of the turntable 2 and the outer peripheral edge of the thick wall portion 2a of the turntable 2, through which the arrayed objects K can be inserted.

[0053] In addition, among the guide surfaces 9a, 10a, and 11a of the outer peripheral guide portion 8, the position of the guide surface 9a of the first outer peripheral guide portion 9 corresponding to the downstream end of the outward guide portion 7 becomes the guide start end 9b, and the position 11b of the guide surface 11a of the third outer peripheral guide portion 11 connected to the discharge guide portion 15 becomes the guide terminal. In addition, an arc-shaped inclined guide member 12 is provided at a portion corresponding to a predetermined length from the guide start end of the first outer peripheral guide portion 9 toward the rotation direction (arrow D direction), as shown in FIG. Figure 4 As shown, the lower surface 12 a of the inclined guide member 12 is connected to the vertical guide surface 9 a of the first outer peripheral guide portion 9 and is an upward inclined surface facing the center side of the turntable 2 .

[0054] Furthermore, the two air discharge nozzles 13 and 14 are provided on the center side of the turntable 2 corresponding to the inclined guide member 12 , and airflows are discharged from the air discharge nozzles 13 and 14 toward the inclined guide member 12 .

[0055] The discharge guide 15 comprises: a first linear guide member 16, one end of which is connected to the guide terminal 11b of the third peripheral guide 11, and the other end of which is extended to the outside of the turntable 2; a second linear guide member 17, which is arranged parallel to the first guide member 16 at a predetermined interval in the same horizontal plane; and a third guide member 18, which is arranged between the first guide member 16 and the second guide member 17. Figure 2 , Figure 3 and Figure 6As shown, the lower surface 18 a of the third guide member 18 is an upwardly inclined surface facing the first guide member 16 .

[0056] According to the arrangement and supply device 1 of this example constructed as described above, first, while the turntable 2 is rotated in the direction of arrow D by the rotation drive mechanism (not shown), irregular-shaped tablets K are appropriately supplied to the rotating turntable 2 from the supply port 20 of the storage device (not shown).

[0057] The supplied irregular-shaped tablet K is transported along the rotation direction (direction of arrow D) of the turntable 2 through its rotation, and comes into sliding contact with the guide surfaces of the first inward guide portion 4, the second inward guide portion 5 and the third inward guide portion 6, thereby gradually approaching the center side of the turntable 2 and reaching the guide surface of the outward guide portion 7.

[0058] Then, the irregular-shaped tablet K reaching the guide surface of the outward guide portion 7 is guided toward the outer peripheral side of the turntable 2 in a state of sliding contact with the guide surface, and is introduced between the guide surface 9a of the first outer peripheral guide portion 9 and the outer peripheral edge of the thick wall portion 2a of the turntable 2. Thereafter, the irregular-shaped tablet K is pushed against the guide surface 9a of the first outer peripheral guide portion 9 by the air flow discharged from the air discharge nozzles 13 and 14, as shown in FIG. Figure 4 As shown, the guide surface 9 a of the first outer peripheral guide portion 9 and the inclined surface 12 a of the inclined guide member 12 are in sliding contact with each other.

[0059] In this way, the irregular-shaped tablets K are reliably embedded between the guide surface 9a of the first peripheral guide portion 9 and the outer peripheral edge of the thick-walled portion 2a of the turntable 2 with their long axes along the conveying direction (direction of arrow D) and with their two surfaces with large curvatures facing the up and down directions through the airflow discharged from the air discharge nozzles 13 and 14. Through this action, the irregular-shaped tablets K are reliably arranged in a row.

[0060] In addition, the irregular tablet K has a property that it is easy to rotate around the long axis, so when it is subjected to the above-mentioned airflow, it is easy to rotate around the long axis without any restriction. However, in this example, when the upper surface of the irregular tablet K is embedded between the guide surface 9a of the first peripheral guide part 9 and the outer peripheral edge of the thick wall part 2a of the turntable 2, it is in a state where the upper surface abuts the inclined surface 12a of the inclined guide part 12. Therefore, the irregular tablet K is prevented from rotating around the long axis by the action of the inclined surface 12a. That is, as Figure 4 As shown, when the arrangement object K attempts to rotate in the direction of arrow G around the major axis, its rotation radius gradually increases, and thus, such rotation is restricted.

[0061] In this example, the arc-shaped chamfered portion 2 c is formed at the outer peripheral corner of the thick wall portion 2 a of the turntable 2 , so that the arrayed objects K can be prevented from being damaged when they come into contact with the outer peripheral corner.

[0062] Then, in this way, the irregular-shaped tablets K in a row that are in sliding contact with the guide surface 9a of the first peripheral guide portion 9 are further transported to the guide terminal 11b in a state of sliding contact with the guide surface 10a of the second peripheral guide portion 10 and the guide surface 11a of the third peripheral guide portion 11 through the rotation of the turntable 2, and are discharged to the outside through the discharge guide portion 15 connected to the guide terminal 11b of the third guide portion 11.

[0063] Specifically, if Figure 2 As shown, the irregular-shaped tablet K enters between the first guide member 16 and the third guide member 18 of the discharge guide portion 15, and is conveyed to the outside of the turntable 2 while its upper surface is in sliding contact with the lower surface of the third guide member 18. Figure 3 and Figure 6 As shown, the lower surface of the third guide member 18 is an upward inclined surface 18a facing the first guide member 16, so that the irregular-shaped tablet K is prevented from rotating about the long axis by the action of the inclined surface 18a.

[0064] That is, Figure 6 As shown, the irregular-shaped tablet K is subjected to friction in the direction of rotation (direction of arrow D) between the turntable 2 and abuts against the inclined surface 18a of the third guide component 18. Therefore, although it wants to rotate in the direction of arrow G with the long axis as the center, its rotation radius gradually increases when rotating in the direction of arrow G. Therefore, these rotations are limited by the inclined surface 18a of the third guide component 18.

[0065] Thus, according to the arrangement and supply device 1 of this example, even irregular-shaped tablets whose plane shape is an oblong, front shape is an elliptical, and cross-sectional shape is approximately circular, and whose static posture is unstable, can be arranged in a row with two surfaces with large curvatures facing the upper and lower sides in a certain posture, and discharged to the outside of the system.

[0066] An embodiment of the present invention has been described above, but specific embodiments of the present invention are not limited thereto.

[0067] For example, the objects to be arranged in the arrangement supply device 1 of the above example are assumed to be irregular-shaped tablets K, but the objects that can be arranged in the arrangement supply device 1 are not limited thereto. As the objects that can be arranged in the arrangement supply device 1 of the above example, in addition to irregular-shaped tablets K, relatively small objects (small objects) such as general tablets, capsules, electronic components such as chip capacitors, candies and other confectionery, washers, and buttons can be exemplified.

[0068] In the above example, the inward guide 3 is composed of the first inward guide 4, the second inward guide 5 and the third inward guide 6, but the present invention is not limited thereto, and the number may be more than three or less than three. In addition, if the array objects supplied from the supply port 20 do not scatter around, the inward guide 3 may not be provided.

[0069] In the above example, the outer peripheral guide 8 is composed of three guides, namely the first outer peripheral guide 9 , the second outer peripheral guide 10 , and the third outer peripheral guide 11 . However, the present invention is not limited thereto and the outer peripheral guide 8 may be divided into a larger number or a smaller number.
