近では生産性向上のため、缶蓋を従来よりも格段に速い
速度（１分間に数百枚）で連続的に自動検査する装置が
検討され始めている。そして、このためには缶蓋を高速
で一枚づつ供給する装置が必要であった。Conventional technologyConventionally, in the manufacturing process of can lids used for soft drink containers, etc., inspections to confirm the scratches of the manufactured can lids and the mounting state of the opening tabs and the like are indispensable. There has been a demand for an inspection device that automatically performs inspection at high speed. For example, recently, in order to improve productivity, an apparatus for continuously and automatically inspecting a can lid at a remarkably faster speed (several hundred sheets per minute) has begun to be studied. For this purpose, a device for supplying the can lids one by one at a high speed was required.
ところが、従来知られているフィーダと称される装置
（例えば水平方向に物品を移送し供給するもの）は動作
速度に限界があり、前記検査装置の高速度化要求に対応
することができなかった。However, a conventionally known device called a feeder (for example, a device for transporting and supplying articles in a horizontal direction) has a limitation in operating speed, and cannot meet the demand for higher speed of the inspection device. .
そこで、出願人は以下のような缶蓋供給装置を発案し
開発した。Therefore, the applicant has devised and developed the following can lid supply device.
すなわち、缶蓋を積層した状態で積層方向に移動自在

る。That is, a holding mechanism that holds the can lids movably in the stacking direction in a stacked state, and inclined grooves that are arranged on both sides of the front row of can lids held by this holding mechanism and have different inclination directions from each other are formed on the outer periphery. In a state in which the stacked can lids are urged toward the feeding cam by gravity or a spring or the like, the feeding cams are rotated in opposite directions to each other. This is a device that feeds the can lid at high speed by a feeding cam that rotates in one direction by simultaneously fitting the outer peripheral portions of the can lids in the front row and moving the can lid in the laminating direction according to the inclination of the inclined groove.
「発明が解決しようとする課題」 ところが、取り込まれた缶蓋（すなわちその外周部が
繰出カムの傾斜溝にはまり込んだ缶蓋）から見るとふた
つの繰出カムの傾斜溝の傾斜方向は同方向であるので、
缶蓋は取り込まれた後にこの傾斜方向に沿うように傾斜
することができる。"Problems to be Solved by the Invention" However, when viewed from the taken-in can lid (that is, the can lid whose outer peripheral portion is fitted into the inclined groove of the feeding cam), the inclination directions of the inclined grooves of the two feeding cams are the same. So that
After the can lid is taken in, the can lid can be inclined so as to follow this inclination direction.
したがって、取り込まれた後にも缶蓋を繰出方向に付

回動するようにしてふらつくことになる。Therefore, in a state where a force such as gravity that urges the can lid in the dispensing direction is applied even after being taken in, the outer peripheral portion of the can lid is pressed against one inner surface of the inclined groove by this force, and the natural can lid Is inclined with respect to a direction perpendicular to the feeding direction (the direction in which the can lids are laminated) along the inclined groove. Further, in the state where the above-described force is not applied, the can lid is swung around the outer peripheral portion fitted into the inclined groove as a center within the range of inclination of the inclined groove.

に、缶蓋に傷が付き易かった。For this reason, for example, at the receiving place of the next process arranged in a direction perpendicular to the dispensing direction (horizontal direction when the dispensing direction is vertical), such as a mounting table of an inspection device, the can lid is inclined or fluctuated. In this state, the container was dropped by an impact, which caused a positional shift at the receiving place, which sometimes caused a malfunction in the next step, and that the can lid was easily damaged.

んで繰り出される。According to the can lid supply device of the present invention, when one of the driving mechanisms of the drive mechanism rotates the feeding cams disposed on both sides of the can lid discharge port in the same direction by one driving source, the first row of the stacked and held row is held. The outer peripheral portion of the can lid fits into the step portion of each of the dispensing cams arranged to face each other. At this time, since each of the step portions is formed along a plane orthogonal to the rotation axis of the feeding cam, the front row of can lids fitted into the step portions is orthogonal to the rotation axis of the feeding cam. The posture that matches the surface (that is, the posture when the layers are held before being stuck in the step portion) is held. Therefore, when the outer peripheral portion of the can lid fits into the step portion of the feeding cam, the outer peripheral portion of the can lid and the step portion gradually come into surface contact with each other, and the outer peripheral portion of the front row can lid has Since the impact upon entry into the part is received not on the narrow part of the step but on the wider surface, local damage or wear on the part of the step hardly occurs, and the can lid The soundness of the outer peripheral portion and the step portion is easily ensured. Next, the outer periphery of the can lid in the state where the posture is maintained is fitted into the inclined groove from the step portion of the delivery cam and is delivered.

Since the inclined grooves are inclined at a predetermined angle in directions opposite to each other with respect to the plane including the rotation axis of each of the feeding cams, at both ends of the outer peripheral portion of the can lid supported by these inclined grooves, The other end functions to prevent it from tilting at one end. Therefore, the can lid does not tilt in any direction, and the feeding direction (along the axis of the feeding cam) is maintained in a state where the can lid is kept at the previous position (the position corresponding to the plane orthogonal to the rotation axis of the feeding cam). Direction).

態を維持したまま載置台Ｓ上に滑らかに落下する。At this time, when the can lid K fits into the inclined groove 18 of the feeding cam 17 and descends, both sides of the outer peripheral convex portion KA are each inclined groove.
While being pressed against the lower surfaces of the inclined grooves 18, the inclined grooves 18 fit into the inclined grooves 18 with almost no gap therebetween as shown in FIG. 8 (a). For this reason, the can lid K falls smoothly onto the mounting table S while maintaining a horizontal state without wobbling.

ない。Therefore, in the above-described can lid supply device 1, the stacked can lids K can be reliably fed one by one at an accurate constant cycle only by rotating each of the feeding cams 17 at a constant speed, and the operation reliability is extremely high. In addition, if the rotation speed of the feeding cam 17 is changed, the supply interval of the can lid K can be adjusted arbitrarily, and the can lid inspection device 2 can easily cope with high-speed processing. Further, since the configuration and the operation are simple, the cost is low and the possibility of failure is small.

缶蓋Ｋに傷が付き難いという効果がある。And when the can lid K descends according to the inclined groove 18,
As described above, since the posture of the can lid K is maintained without fluctuation in the horizontal direction (the direction perpendicular to the feeding direction), the can lid K falls smoothly and horizontally on the mounting table S. For this reason, the mounting table S
It does not hinder the positioning on the top and eliminates the malfunction of the next step (in this case, the can lid inspection device 2),
There is an effect that the can lid K is hardly damaged.

付きにくいという利点も有する。Further, in this apparatus 1, while the feeding cam 17 is formed of resin or surface-treated metal, the metal plate 21 is fixed on the upper surface thereof. At the same time, since the contact between the inclined groove 18 and the can lid K can be softened, the width of the inclined groove 18 hardly increases due to wear. Even if this width increases due to abrasion, the metal lid 21 separates the lowermost can lid K from the succeeding can lid K as described above, so that the can lid K is always lowered by one sheet and fed out. . Therefore, there is an advantage that the function of feeding out one sheet at a time is maintained even in long-term use, and the can lid K is hardly scratched here because the impact upon entering the inclined groove is small.

It may be larger than a value satisfying the condition as shown. That is, even in this case, as shown in FIG. 8 (b), both ends of the outer peripheral convex portion KA of the can lid are pressed against the lower surface of the large inclined groove 18a, so that there is a gap on the upper surface side of the inclined groove 18a. However, the can lid maintains a horizontal state.

を有する。[Effects of the Invention] As described above, according to the can lid supply device of the present invention, since the step is formed along the surface perpendicular to the rotation axis of the feeding cam, the front row of the stacked and held front row is formed. When the outer peripheral portion of the can lid fits into the step portion of the feeding cam as the feeding cam rotates, the front lid can fit into the step portion coincides with a plane orthogonal to the rotation axis of the feeding cam. By holding the adjusted posture (the posture at the time of stacking and holding before being stuck in the step portion), the outer peripheral portion of the can lid and the step portion of the feeding cam can be gently brought into surface contact with each other. The impact of the outer peripheral portion of the can lid upon entering the step portion can be received not by a narrow portion of a portion of the step portion but by a wider surface, and therefore, a local portion can be received by a part of the step portion. Damage and abrasion can be prevented, and the soundness of the outer periphery and step of the can lid Can be easily secured. In addition, since the inclined grooves of the dispensing cams disposed opposite to each other have the same inclination direction and inclination angle, and each dispensing cam is rotated in the same direction by one drive source of the drive mechanism, the can lid is moved from the step portion. In the state of being delivered to the inclined grooves, the inclined grooves of the respective feeding cams supporting both ends of the outer peripheral portion of the can lid are inclined at predetermined angles in directions opposite to each other with respect to a plane including the rotation axis of the both feeding cams. Therefore, at both ends of the outer peripheral portion of the can lid supported by these inclined grooves, when one end of the can lid attempts to incline, the other end functions to prevent it, and therefore, Without tilting in any direction,
The feed can be smoothly performed in the feeding direction (the direction along the axis of the feeding cam) in a state in which the attitude up to that point (the attitude matching the plane orthogonal to the rotation axis of the feeding cam) is securely held. As described above, when the can lid is extended by the respective extension cams, the posture of the can lid is maintained without swaying in the direction orthogonal to the extension direction, so that the mounting surface of the receiving location in the next process is moved in this direction. In this case, the can lid is smoothly placed on the placement surface. For this reason, there is no effect on the positioning at the receiving location of the next process, and it is possible to prevent the operation failure of the next process and to prevent the can lid from being easily damaged. Furthermore, since each of the dispensing cams disposed opposite to each other is rotated in the same direction by one driving source of the driving mechanism, it is possible to easily synchronize the respective dispensing cams and adjust the timing between the respective dispensing cams. Can be easily performed. In addition, by simply rotating each feeding cam at a constant speed, the stacked can lids can be reliably fed one by one at a constant cycle, and the operation reliability is high. The supply interval of the can lid can be adjusted, and it is easy to respond to high speed. In addition, since the configuration is simple, there are advantages that the cost is low and the possibility of failure is small.
