A wrapping means for dividing the work discharged by opening of each pool shutter for each type and wrapping the divided work; and when a wrapping completion signal is issued from the wrapping means, the unopened pool shutter is opened based on the stored value of the storage means. Determining means for determining a pool shutter pooling a predetermined number of works from
When the determination means determines that the number of pool shutters pooling the predetermined number of works is single, the pool shutter is controlled to be opened, and when the number is determined to be plural, control is performed to control opening of any one of the pool shutters. Means, and reset means for resetting the stored value of the storage means when the divisional packaging for each type of work is completed once for all types.

Further, the present invention is characterized in that a cutter device is provided which is driven when divisional packaging for each type of work is completed once for all types.

[0007]

According to the first configuration, when the packaging of the predetermined number of works by the packaging means is completed, the predetermined number of works are pooled from the unopened pool shutters based on the value stored in the storage means. Since the open pool shutter is controlled to be opened, the same type of work is not packed in a bag until the divisional packaging for each type of work is completed once for all types. Therefore, unlike the conventional case, various kinds of works are not mixed and packed in a bag, so that only necessary works can be easily taken out from the works counted for each predetermined number and used.

Further, according to the above-mentioned second configuration, it is possible to cut a single set of works divided and packaged for all types. Therefore, when a combination of works such as bolts, nuts and washers is used, these works can be carried as a set, which is very convenient.

The counting for each type of work is started by the detection sensors 2a, 2b, and 2c.

In # 2, when the counting completion signal from the comparator is confirmed, it is determined whether there are a plurality of such signals (# 3). In # 3, when there are a plurality of count completion signals, a pool shutter having a predetermined high priority is selected from among the pool shutters whose flags are 0 (# 4). On the other hand, if there is only one counting completion signal in # 3, the pool shutter whose counting has been completed is selected as it is (# 5).

Next, the flag of the pool shutter selected in # 4 and # 5 is set to 1 (# 6), and the pool shutter is opened to discharge the work to the packaging machine 6. In # 7, the packaging machine 6 is driven to start bagging of the work discharged from the pool shutter, and the pool shutter in the opened state is closed. In step # 8, the feeder which has been stopped after the counting is completed is re-driven to supply the work, and the counting of the work by the passage detection sensor is restarted.

At # 9, when the packing is completed and a packaging completion signal is issued from the comparator, it is determined whether or not a flag of 0 exists (# 10). If there is a flag of 0 in # 10, the process returns to # 2 and repeats a series of operations. On the other hand, when it is confirmed that the flag of 0 does not exist (that is, all the bagging for all types of workpieces is completed),
