Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus that classifies workpieces sent from a previous process by storing them in sticks corresponding to the ranks based on the designated ranks.

2. Description of the Related Art A conventional ranking stocker device is based on the structure shown in FIG. That is, 2 is a magazine having a plurality of rows of grooves, and a rank is assigned to each groove. 3
is a single-axis robot that can perform multi-point (valley) positioning, and the workpiece 1 sent from the previous process is transferred to the groove position of the magazine 2 corresponding to the specified rank by this single-axis robot 3, and then transferred to the workpiece pusher. 4, place workpiece 1 in the groove.
is pressed and stored. In addition, a full sensor 5 is installed at the end of the magazine 2, and a workpiece 1 of a certain rank is
When the full sensor 5 comes into contact with the full sensor 5, the device comes to a steady stop. When the operator takes out the workpiece 1 of that rank from the magazine 2, the apparatus becomes ready to start again.

Problems to be Solved by the Invention However, according to the stocker device as described above,
If any one rank becomes full, the device will stop. The distribution of ranks is often close to a normal distribution, and there is a high probability that the ranks near the center will be full, and in this case, the ranks near the ends are relatively empty and space efficiency is reduced. bad. Furthermore, whenever the equipment stops, a worker must intervene to restart it.

Furthermore, since the rank of the workpiece is no longer known once the workpiece is dispensed from the magazine, there is also the drawback that the rank must be memorized by another means.

Therefore, the present invention improves the efficiency of storage space by ranking,
Furthermore, it is designed to be able to be stocked for long periods of time.

Means for Solving the Problem The technical means for solving the above problem is to use a stick that can store a plurality of workpieces, and a stick magazine section in which a plurality of sticks are arranged in order to store the workpieces in ranks. , a marking section that stamps ranks on sticks, a stick supply section that supplies empty sticks, a stick storage section that stores full sticks, and a transfer unit that transfers workpieces and sticks to each rank position. It has the following.

Operation With the above configuration, workpieces are stored in sticks arranged in the stick magazine section, and when the sticks are full, the sticks are taken out by the transfer unit and transferred to the stick storage section. Next, an empty stick is supplied from the supply section, and after being stamped by the marking section, it is transferred to the empty rank position of the stick magazine section. Therefore, the device can operate for a long time without stopping until the stick storage section is full of sticks, and the space efficiency as a stocker is also improved.

Embodiment An embodiment of the present invention will be described below with reference to FIG. In the figure, 8 is a stick magazine in which sticks 7 are arranged and ranks are assigned to each stick. 9
is a single-axis robot capable of multi-point positioning.The single-axis robot 9 transfers the workpiece 6 sent from the previous process to the position of the stick 7 of the estimated rank.The workpiece pusher 11 transfers the workpiece to the stick 7. 6 is pressed and stored. The number of works 6 stored in the stick 7 is counted and when it is full, the 1 Tsumugi robot 9 will
The full stick 7 is chucked by a stick chuck 10 and transferred to a stick slide feed u14. The stick 7 is stick slide feed u
14, the stick is transferred to the full stick stocker 16, and the full stick is stored in the stick stocker 16 by the stick pitch feed u15. Also, the empty stick 7 is sent from the empty stick supply u12 to the stamp u13, the rank of the vacant seat is printed, and the one-axis robot 9
Thus, the printed stick 7 is chucked by the stick chuck 10 and transferred to a vacant rank position in the stick magazine 8.

Thereafter, the work 6 is stored in the sticks 7 in the stick magazine 8, and when a certain stick 7 is full, it is taken out, and an empty stick 7 is stamped and supplied, and a series of □ operations are repeated.

A full sensor 17 is installed in the full stick stocker 16, and the full sticks 7 are sent one after another, and when the sticks 7 come in contact with the full sensor 17, the device stops at a steady state. By discharging the sticks 7 from the full stick stocker 16, the device is ready to start again.

In addition to the effects of the invention, according to the present invention, even if a stick of a certain rank becomes full, the full stick is automatically taken out and a new empty stick is supplied, making it possible to stock the stick for a long time. be.

In addition, when ranks occur in a form close to a normal distribution, space efficiency was extremely poor in the past, but in the present invention, even if the sticks of ranks near the center become full faster than the pond, Since sticks are replaced when each stick is full, there is little difference in the work storage status within the stick depending on the rank, and by installing a dedicated stocker for full sticks, space efficiency has been improved compared to the past.

Furthermore, in the conventional case, when a workpiece is taken out from a magazine, the rank of the workpiece is lost, but with the present invention, even if a stick is taken out from a full stick stocker, the rank is printed on the stick. , it is easier to handle in terms of operation in subsequent processes.
