Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a round stocker for storing small parts discharged from a discharge port of a manufacturing machine.

[0002]

[Prior art]

 Conventionally, small items that have been machined and intertwined with each other, such as springs and stamped products, have been stored in a temporary stocker after machining and sent to the next process after checking defective products and counting. Here, the following various stockers were used. Method using a large stocker alone: It can be stored unattended for a long time, but a large amount of stored small parts are entangled and it takes a lot of time to disassemble the parts. In order to prevent this entanglement, small parts are sometimes packaged, but there is a problem that the packaging cost increases.

Further, as counting management, estimation based on a weighing result is performed, but it is not always accurate, and an error occurs, which is a problem. If lots have to be sorted more frequently, personnel for stocker replacement will be required. Method using a small stocker alone: It is more effective than a large stocker in dividing lots and preventing entanglement, but it cannot be stored unattended for a long time, and requires personnel to replace the small stocker, so it is unattended at night. There is a problem that the operation is impossible. Round stocker proposed by the present inventor: The present invention has been recently devised to solve the above drawbacks, and will be described with reference to FIGS. 2, 3 and 4.

The casing 23, on which the guide pot 22 is placed and held, is continuously rotated by a rotating device composed of a motor 25, an iron piece 26, and a proximity switch 27 shown in FIG. This casing is supported by a column 60 with an operation panel 30 (2) fixedly mounted on a gantry 70 with casters 80. It has also been attempted to open the lower part of the guide pot 22 as shown in FIG. 4, attach a bag 24 for storing small parts, and transfer the small parts to the bag. The round stocker was placed just below the discharge port of the small parts manufacturing machine, and the small parts discharged from the discharge port were stored in the guide pot by setting the desired setting value with either a counter or a timer.

[0005]

[Problems to be solved by the device]

In the conventional round stocker (see FIG. 2) devised by the present inventor, since the guide pot rotates and moves by the timer and the counter and can receive small parts, counting management of small parts such as springs for each guide spot. Was made accurately. However, in the conventional round stocker, the capacity of the guide pot must be above a certain value in order to receive a certain number of small parts. Therefore, L ₇ in FIG. 2 is, for example, 100 to 150 m / m, while L ₆ is, for example, 450 m / m due to the columns, operation panel 30 (2), etc., and the total height L ₅ of the round stocker including the gantry is L _5. Reaches 700-800m / m. Therefore, there is a problem that the conventional round stocker cannot be applied when the discharge port of the small component manufacturing machine is located at a position lower than the total height L ₅ .

The present invention has been made to solve the above problems and to provide a round stocker capable of increasing the capacity of a receiving box.

[0007]

[Means for Solving the Problems]

 The present invention comprises a plurality of receiving boxes for accommodating small parts and a receiving plate for placing the receiving boxes in an annular shape. One of the receiving boxes faces directly below the discharge port of the small part manufacturing machine. A round stocker for rotating the receiving plate intermittently, in which the receiving plate mounting area on the upper surface of the receiving plate is an outer peripheral annular area radially divided from the center of rotation of the receiving plate, and the planar shape of the receiving box is in front. It is a round stocker in which a storage unit including a receiving box that is substantially the same as the storage area is directly mounted on a control panel that controls the intermittent rotation of the storage unit.

[0008]

In the round stocker according to the present invention, a plurality of receiving boxes are continuously arranged in an annular shape instead of the conventional guide pot, so that the dead space between the guide pots as in the conventional case is eliminated and the round stocker is eliminated. When the diameter is the same (R ₁ = R ₂ ), the effective area for receiving small parts according to the present invention is significantly widened, and if the height is the same, the storage amount is further increased, while if the storage amount is the same, the height is significantly increased. Can be lowered. Furthermore, since the round stocker was placed directly on the horizontal control panel 30 (1) without using the support 60, the total height of the round stocker could be significantly reduced.

Therefore, compared with the round stocker proposed by the present inventor, the total height can be remarkably reduced, and the present invention can be applied to the case where the discharge port of the small component manufacturing machine is at a low position. On the other hand, in the round stocker having the same diameter, the capacity of the receiving box can be increased or the number of receiving boxes can be increased as needed, so that unmanned operation for a longer time can be supported.

Compared to the conventional method using a stocker alone, the counting management can be performed more accurately, and in the past, all the stored products were discarded due to entanglement etc. even if one defective product was mixed in. With the stocker related to (3), lots can be easily divided, so it is possible to improve yield without disposing of all products and to deal with entanglement. In addition, the time and management of products can be handled unattended.

【Example】

An embodiment of the present invention will be described with reference to FIG. The round stocker 10 of the present invention comprises a storage unit 20 and a control panel 30 (1). The storage unit is composed of a receiving plate 90 that is radially provided from the center of rotation of the receiving plate 90, and a plurality of receiving boxes 21 placed on the receiving plate and arranged in an annular shape. Here, when the diameter R ₁ is 400 m / m which is almost the same as the conventional diameter R ₂ , L ₁ = 120 m / m and L ₂ = 160 m / m. Here, the proximity switch 27 is built in the control panel 30 (1), and the iron piece 26 is arranged below the receiving plate so as to correspond to the receiving box 21 to control the rotation of the storage section.

The control panel 30 (1) is provided with a counter 31, a timer 32, etc., and either the number control (management) of small parts or the time control can be selected, and the intermittent rotation of the storage unit can be selected according to this selection. Control Here, L ₃ = 70 m / m and L ₄ = 350 m / m of the control panel. Therefore, the total height of the round stocker of this proposal can be kept within 300 m / m. Furthermore, comparing the volume of the conventional round stocker with six guide pots (see FIG. 2) according to the present inventor's invention and the receiving box of the present invention with the same storage diameter, the present invention is more It can reach up to 4 times and can be stored for a longer time.

As described above, according to the present invention, the total height of the round stocker can be remarkably reduced, it can be applied to a manufacturing machine with a low discharge port, and the volume of the receiving box can be increased to enable long-term storage. In addition, compared to the conventional method using a stocker alone, counting control can be performed more accurately, yield can be prevented from being entangled and defective products are mixed, and check by customer can also be performed hourly by unattended operation. .

[Effect of device]

 As described above, the round stocker according to the present invention is superior in applicability and long-term storage to the conventional one. In addition, compared with the stocker alone, it has significant effects in terms of counting management and product yield.
