Description

  The present invention relates to a component supply counter that stores a predetermined amount of components such as screws, bolts, nuts, or rivets, and supplies the components in a row while arranging and supplying them, thereby enabling counting.

  In general, the number of these parts is counted in parts such as bagging and boxing of parts, but this counting is performed by a job or part, or the weight (unit weight) per reference number is measured in advance, and the total number of parts for this is measured. There are methods such as measuring the weight and calculating the total number of parts. When packing a certain number of parts in the above-mentioned job or part, it can be handled if the number of parts to be counted is small, but if it is necessary to count more parts than this, the number is calculated from the weight. ing. However, if the parts are small, the number may not be accurate due to the measured weight error. In addition, the accuracy of the number is not good due to the reading error of the operator, and the reliability is questioned.

In order to solve such a question, recently, parts are arranged and supplied by a supply machine, and the number of parts is automatically read using a counting sensor. An example of such a component counting apparatus is shown in Japanese Patent Laid-Open No. 3-56312. As shown in FIG. 5, one component m is sent from the discharge end 114 of the component transfer track 112 by driving the vibrating parts feeder 110 containing the component m, and this is sent to the discharge end 114 of the transfer track 112. This is a device that counts by a component counting device 140 provided in the vicinity.
JP-A-3-56312

  However, in the parts counting apparatus in which parts are arranged and supplied by the vibrating parts feeder and the parts counting device is arranged near the discharge end of the transfer truck, the vibrating parts feeder is driven in a state where a large number of parts are stored. And parts are supplied while overlapping on the truck of the vibration parts feeder, and the overlap is solved to some extent during this supply, but the parts are not completely separated on the truck until reaching the discharge end of the truck, so When these components are overlapped or connected, they pass through the component counting device, and there are cases where a plurality of components are counted as one, and an accurate number cannot be counted. Further, in order to reliably separate the parts by the vibrating parts feeder and align them to one, it is necessary to make the transfer track sufficiently long, so that the entire apparatus becomes large. Furthermore, as in the conventional example, in order to prevent a large amount of parts from being stored in the vibration parts feeder, a vibration feeder that stores a large amount of parts is placed separately in this vibration parts feeder, and a small amount of parts are now stored in the vibration parts feeder. In this case, the size of the apparatus is inevitably increased, which hinders lighter and smaller parts counters. In addition, there are problems such as an increase in the cost of the component counter due to the combination of such a large number of devices.

  An object of the present invention is to obtain an inexpensive component supply counter that solves such problems and has a simple structure and enables accurate counting.

  An object of the present invention is to store a predetermined amount of component A in a component supply counter that counts the component A that is aligned and supplied by providing a counting unit 40 at the component discharge end of the component supply unit that supplies and supplies the component A by a predetermined amount. The component supply unit is composed of a component storage and supply unit 1 that supplies and aligns the components A, and a feeder unit 30 that receives the components A and aligns them in a line and supplies them forward with a gap between the components, This is achieved by providing a component supply counter in which a counting unit 40 for counting the components A discharged from the feeder unit 30 is provided at the component discharge end of the feeder unit 30.

  In order to achieve this object, in the configuration of the component supply counter, the component storage and supply unit 1 includes a cylindrical drum 10 with a bottom that is open at one end and closed at the other end, and is disposed at an angle. The drum 10 includes a rotation drive transmission unit 20 that rotates in the circumferential direction. A component supply path 12 that spirally extends from the bottom toward the open end is formed on the inner periphery of the drum 10. Since the component A is guided by the component supply path 12 and moved to the open end side of the drum 10 by rotating in the direction, noise is reduced. Further, in addition to these configurations, the drum component supply path is formed such that the height from the inner peripheral surface 11 of the drum 10 is lower than the height of the other component supply paths 12 by at least one turn on the open end side. Therefore, even if the parts are overlapped at this point, the overlapped parts are returned to the inside of the drum and supplied after being overlapped.

  In addition, in order to achieve the above object, the feeder portion has a transfer path 31 having a V-shaped cross section, and the component A is supplied forward along the transfer path 31 by the vibration unit 32 provided at the lower part thereof. In addition, a dust discharge slit 33 is provided at the V-shaped bottom near the terminal end of the transfer path 31 below the open end of the component storage and supply unit 1 and serving as the discharge end of the component A. Since the component supply counter is formed, the components supplied from the component storage and supply unit can be supplied with a gap therebetween.

  According to the present invention, even when there is an overlap at the start of component supply, the component is reliably unwound during supply from the component storage supply unit via the feeder unit, and a gap is formed between the components. Therefore, the parts that have reached the counting unit are accurately counted, and a plurality of parts are not supplied in series, thereby preventing a plurality of parts from being counted as one. In addition, since the component storage and supply unit is not a vibrating parts feeder but a rotating drum, noise is reduced and the supply of components is smooth. Furthermore, since the cylindrical drum and the feeder section having a V-shaped transfer path for aligning and supplying the parts to be supplied from now on are combined, the entire supply counter is smaller than the conventional one, and the entire machine is reduced. It becomes lightweight. In addition, if you prepare multiple drums that make up this parts storage and supply unit and store different parts in each of them, you can immediately count different parts, and you can immediately respond to changes in counting parts. is there. In addition, by preparing the drums according to different parts, it is possible to obtain specific effects such as eliminating the problem of mixing different kinds of parts.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2, reference numeral 10 denotes a cylindrical drum for storing a predetermined amount of parts A such as screws, bolts, nuts, or rivets. The drum 10 is placed on the drum 10 and rotated in the circumferential direction. The component storage and supply unit 1 is constituted by the transmission unit 20. The drum 10 has a bottomed cylindrical shape with one end open and the other end closed, and is arranged in an inclined state with the open end side up and the bottom down. As shown in FIG. 3, a component supply path 12 extending in a spiral shape from the bottom toward the open end is formed on the inner peripheral surface 11 of the drum 10. The component supply path 12 has a predetermined height from the inner peripheral surface 11 of the drum 10, and the component A slides on the supply path 12 by rotating the drum 10 while being inclined. The component A gradually moves to the open end side of the drum 10. The component supply path 12 of the drum 10 is formed so that the height from the inner peripheral surface 11 of the drum 10 is lower than the height of the other component supply paths 12 at the open end side by at most one round. It is set to the same level as the height of one. Thereby, even if the overlapping of the parts A occurs, the overlapping part A is configured to return from the part supply path 12 to the bottom side of the drum 10 at this part.

  On the other hand, a first gear 13 is formed on the outer periphery on the bottom surface side formed on the drum 10, and a second gear 21 constituting the rotational drive transmission unit 20 is engaged with the first gear 13. The second gear 21 can be rotated by a motor 23 fixed to the frame 22 of the rotational drive transmission unit 20, and the peripheral speed of the drum 10 can be arbitrarily changed by changing the ratio of the gears 13 and 21. It is possible. In addition, a rotation support body 25 rotatably attached to a support column 24 fixed to the frame 22 is in contact with the center of the bottom of the drum 10, and the drum 10 is inclined with the open end side up. A spherical support body 26 that supports the outer peripheral surface of the drum 10 during rotation thereof is provided on the inner side of the V-shape of the supporting frame 22 so as to guide the drum 10 when the drum 10 rotates in an inclined state. It has become.

  Further, as shown in FIG. 1 and FIG. 3, a feeder part 30 in which a part A discharged from the drum 10 is arranged linearly below and slightly inclined at the end side, just below the open end side. A guide chute 27 is disposed on the transfer path 31, and the transfer path 31 is attached to the support 2 via a vibration unit 32 provided at the lower portion of the transfer chute 31. A is supplied forward along the transfer path 31. As shown in FIG. 4, the transfer path 31 has a V-shaped cross section, has a start end below the guide chute 27 from the open end of the component storage and supply unit 1, and a discharge end of the component A A slit 33 for discharging dust is formed in the V-shaped bottom near the terminal end. The slits 33 are spaced so that at most the parts A to be supplied do not fit into them, and the case 3 for collecting dust (not shown) mixed with the parts A and supplied below the slits 33. Is arranged.

  In such a component supply unit including the component storage and supply unit 1 and the feeder unit 30, a sensor that constitutes a counting unit 40 that counts the component A falling from the transfer path 31 near the lower end of the transfer path 31. The photoelectric sensor 41 is fixed to the support 2 so as to be adjustable in position, and the component A transmits a counting signal by blocking between the light emitting side and the light receiving side of the photoelectric sensor 41. is there. Any sensor may be used as long as it detects the passage of the component A instead of the photoelectric sensor 41.

  In such a configuration, when a predetermined amount of component A is stored in the drum 10 of the component storage and supply unit 1 in advance and a start signal is input thereafter, the component A is rotated by the rotation of the drum 10 as shown in FIG. The drum 10 is gradually supplied to the open end side along the supply path 12. In this way, when the part A reaches the open end, the part A sequentially falls from the open end and falls onto the transfer path 31 below from the guide chute 27. At this time, the part A overlapping on the part supply path 12 in the drum 10 has the same height as the part A in the vicinity of the open end. 10, the parts A remaining on the parts supply path 12 are aligned, addressed to one, and sequentially fall from the open end of the drum 10.

  Then, the parts A that have fallen are supplied in line by the transfer path 31 that vibrates and supplies the parts A toward the end of the transfer path 31 while eliminating the connection between the parts. On the other hand, fine dust adhering to the component A during the supply or mixed with the component A is separated from the component A and moves to the end on the transfer path 31, but a slit 33 is formed in the middle. Therefore, dust falls from the slit 33 into the lower case 3 and is collected. Further, when the part A reaches the end of the transfer path 31, one part A falls to one and is counted by the photoelectric sensor 41.

  In this embodiment, a bag or a box for storing the component A after counting is not shown, but it is naturally possible to store it for a predetermined number. In this case, it is set in advance. When the predetermined number is counted, it is possible to stop the supply. After that, by repeating the counting operation again, it is naturally possible to pack or pack the predetermined number of bags. It is. In addition, the component supply counter can be used for various purposes.

It is a front view of the component supply counter of this invention. It is a top view of FIG. It is a principal part expanded sectional view of this invention.
