[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vacuum type separation / conveyance apparatus for separating and conveying a large number of articles one by one.

[0002]

[Prior art]

 In general, when metal machine parts such as screws and nuts are packed in a bag for sale, the machine parts are counted and packed into a predetermined number of bags. In this case, it is not easy to manually count and pack the bags one by one, so the bags are packed while weighing the total weight with a weighing machine. However, this method of measuring the total weight has a problem that the error in quantity is large when the parts are small and light. For this reason, permanent magnets are embedded in the outer periphery of the rotating plate at a predetermined interval, and many components supplied from the hopper are brought into contact with the outer periphery of the rotating plate to rotate while attracting one by one to the permanent magnet, A method is used in which the quantity is counted at the discharge section and packed into bags from the discharge chute.

However, this magnetic adsorption type counting device can count only magnetic materials, and cannot be applied to nonmagnetic materials such as a silicon cap attached to a small light bulb. Also in the method of measuring the total weight, since the silicon cap is a molded product, the weight of the parts varies, and since silicon is easily charged with static electricity, it adheres to the wall surface of the hopper and the discharge chute to block the passage. However, in the past, each item was manually counted and packed in bags by hand.

Further, in the assembly line of electronic equipment parts, fine parts are soldered, but before the work, the parts are aligned and arranged in a box in advance, and when the assembly line is operated, the parts arranged in the box are arranged. Since one by one is picked up and soldered, there is a problem that the preparation work is troublesome. Also, when packing fruits such as apples and pears in boxes, there is a device that automatically sorts the fruits into a predetermined size with a weight sorter, but at the stage of packing the fruits, the stock that collects the selected fruits is stocked. I picked one from the table and packed it in a box. For this reason, one fruit is arbitrarily taken out from a large number of fruits accumulated on the stock table, so that the work range becomes wide and there is a problem that tires are felt when working for a long time.

[Action]

 The vacuum type separation / conveyance device of the present invention supplies an article from a supply device such as a hopper and a conveyor while operating a vacuum pump and driving a motor to rotate a vacuum drum. Since the air in the hollow part of the vacuum drum is exhausted by the vacuum pump, the outside air is sucked into the hollow part from the air suction hole of the vacuum drum, and when the air suction hole rotates and passes through the supply device, only one item is fed. Adsorb. When the vacuum drum is conveyed to the vicinity of the discharge chute, the adsorbed articles fall off and are discharged by the discharge chute, and are supplied to a bag or the like provided under the discharge chute.

Further, in the apparatus according to the second aspect, when the vacuum drum rotates and the article sucked in the air suction hole is conveyed near the discharge chute, the detection sensor detects the article and counts it. .

【Example】

 Hereinafter, the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 denotes a vacuum drum, which is a cylindrical hollow drum 3 having a hollow portion 2 formed on the inner side thereof, and circular air suction holes 4 ... Are opened at predetermined intervals as shown in FIG. And communicates with the inner hollow portion 2. Further, as shown in FIG. 2, a circular hole 5 is opened in the hollow portion 2 of the hollow drum 3, and a bearing 6 is attached to the inner peripheral portion thereof. Reference numeral 7 denotes a hollow support shaft, inside which an exhaust passage 8 is formed. A support shaft 7 is inserted into a circular hole 5 in the center of the hollow drum 3, and the vacuum drum 1 is supported by a bearing 6 so as to rotate around the support shaft 7.

Further, as shown in FIGS. 1 and 4, an air shield plate 9 in the form of a half ring is tilted and fixed to the outer periphery of the support shaft 7, and is inserted into the hollow portion 2 of the vacuum drum 1 and is attached to the lower portion. The air suction holes 4 on the side are close to and closed. Further, the exhaust passage 8 inside the support shaft 7 is connected to a vacuum pump 12 via a tube 11 as shown in FIG. A flange 13 is fixed to the side surface of the vacuum drum 1, and the flange 13 is connected to a rotating shaft 15 of a motor 14 via a coupling 16. The rotation of the motor 14 causes the vacuum drum 1 to support the supporting shaft 7. It is designed to rotate around the center.

Reference numeral 18 denotes a supply hopper, the tip of which is attached in contact with the outer periphery of the vacuum drum 1 as shown in FIG. 1, and further at a position on the opposite side of the vacuum drum 1 on the rotational direction side, and at the outer periphery thereof. A discharge chute 19 is provided in close proximity. A detection sensor 21, such as an optical sensor, is mounted on the inlet side of the discharge shoe 19 close to the outer circumference of the vacuum drum 1. Further, the detection sensor 21 is connected to the motor 14 via a counter 22 and a control device 23. It is connected.

A case will be described in which the vacuum type separation / conveyance apparatus having the above-described configuration counts the silicon caps 24 to be put on the small light bulbs and packs the constant number of bags. First, the cap 24 is put into the supply hopper 18, the vacuum pump 12 is operated, and the pulse motor 14 is driven to rotate the vacuum drum 1. As shown in FIG. 2, the air in the hollow portion 2 of the vacuum drum 1 is exhausted by the vacuum pump 12 through the exhaust passage 8 of the hollow support shaft 7, so that the outside air is discharged from the air suction hole 4 of the vacuum drum 1. It is sucked into the empty space 2. Therefore, when the air suction hole 4 passes through the supply hopper 18 while rotating, it comes into contact with the cap 24 stored in the supply hopper 18 and adsorbs only one cap 24 as shown in FIG. Since the cap 24 is formed of soft silicon, the cap 24 is easily deformed, and the cap 24 rotates while being attracted while being inclined in various directions.

When the vacuum drum 1 is conveyed to the vicinity of the discharge chute 19, the detection sensor 21 detects the cap 24, and the detection signal is counted by the counter 22 shown in FIG. When the counted cap 24 further rotates and reaches the half-ring-shaped air shield plate 9 fixed inside the hollow drum 3 which rotates as shown in FIG. 4, the air suction hole 4 sucks air. When it disappears, the sucked cap 24 is peeled off, falls on the discharge chute 19 and is discharged, and is supplied into a bag (not shown) provided below this.

In this way, for example, when 100 caps 24 are packed in a bag, when the detection sensor 21 and the counter 22 count 90, the control device 23 outputs a signal to slow down the rotation speed to the pulse motor 14. Then, the remaining 10 are slowly transported and once 100 bags have been packed, the bag is temporarily stopped and waits until the next bag is set. When the bag setting is completed, the vacuum drum 1 rotates at high speed again to start the next bag packing. In this way, the silicon cap 24, which is electrostatically charged and easy to adhere, is forcibly adsorbed and conveyed one by one by the rotating air suction hole 4, detected by the detection sensor 21, and further counted by the counter 22. Since the bag is packed while it is packed, the workability can be improved and an accurate quantity can be packed as compared with the method of packing while manually counting.

In the above description, the case where the cap 24 is packed in a constant number of bags has been described. However, the present invention is also applied to a case where a short cut rubber tube, small vegetables or fruit seeds are packed in a constant number of bags. be able to.

5 and 6 show another embodiment of the present invention, in which an elongated groove 26 is formed on the outer circumference of the vacuum drum 1 along the axial direction. Three air suction holes 4 ... Are connected to the hollow portion 2 at the bottom. Further, three detection sensors 21a, 21b, 21c are arranged in parallel near the outer circumference of the vacuum drum 1. In this separating / conveying device, the capsules 27 fitted into the concave grooves 26 are adsorbed and conveyed only when they are aligned in the axial direction of the vacuum drum 1 by the air suction holes 4 ... The capsule 27 in the direction that does not match the groove shape is not transported because it has a small suction force. If the capsule 27 is transported while being obliquely suctioned as shown in FIG. 5, the three detection sensors 21a, 21b, The air is jetted from an air jet pipe (not shown) to blow the capsule 27 laterally so as not to fall onto the discharge chute 19 as detected by 21c.

FIG. 7 shows another embodiment of the present invention, in which a concave groove 26 is formed on the outer periphery of the vacuum drum 1 so as to fit the electronic component whose one end side is thin. The individual air suction holes 4 ... Are formed in communication with the hollow portion 2. In this structure, when the direction of the electronic component and the shape of the concave groove 26 match, the electronic component is sucked and conveyed. For this reason, the electronic components whose directions are aligned are conveyed at predetermined time intervals, so that workability can be improved when components are mounted on an assembly line of electronic equipment.

FIG. 8 shows another embodiment of the present invention, in which air suction holes 4 having a large inner diameter are opened at a predetermined interval on the outer circumference of the vacuum drum 1 and formed into a ring shape with soft rubber. The formed cushion 28 is attached. This separating and conveying device separates the fruits 29 one by one and conveys them, so that the packing work is easy.

FIG. 9 shows another embodiment of the present invention in which the outer periphery of the vacuum drum 1 is formed in a polygonal shape, and an air suction hole 4 communicating with the hollow portion 2 is formed at the center of each side. With this structure, the contact area with the article to be adsorbed becomes large, and it is possible to adsorb stably.

In the above embodiment, the parts are supplied from the supply hopper 18, but the parts may be continuously supplied from the belt conveyor, or the parts sent from the parts feeder may be separated one by one. Can also be applied to. In the above embodiment, the half shield ring-shaped air shield plate 9 is provided to close the air suction hole 4 and the suction of the article reaching the discharge chute 19 is stopped and dropped, but a scraper is provided.
