Description

Terminal for picking work {TERMINAL FOR PICKING OPERATION}

The present invention relates to a picking operation terminal having an instruction means for instructing an operator of a picking (take-out of parts) timing and a lever switch used for confirming the completion of the picking.

Conventionally, in a factory where assembly production is carried out, parts required for assembling each product are picked up (taken out) from a parts shelf in which each part is stored and delivered to the assembly line of each product. In the case of assembling and manufacturing various kinds of products, the parts picked from the parts shelf are different from product to product, and therefore, the operator must pick a predetermined part from the parts shelf for each product.

In many factories, one or more indicators are provided at the take-out position for each part of the parts shelf to support such a picking operation. The picking apparatus is introduced in order to control lighting of each indicator (refer patent document 1). This picking device lights up and displays a part that requires picking for each assembled product, and notifies the part to the operator. In addition, the picking device instructs the picking timing of the component. This picking device is provided with a lever switch for each indicator. The lever switch is a switch operated to confirm that the picking is completed when the picking of the component corresponding to the lit indicator is completed. When the picking device receives a response to confirm completion of picking from all the lever switches corresponding to the lit indicator (when the lever switch is operated), the picking device recognizes that all parts are picked and notifies the operator of the fact. The picking device is then moved to the picking operation of the product to be assembled next.

In the lever switch used here, for example, there is a simple contact switch as mentioned in Patent Document 2. The simple contact switch includes an operation lever, a rod-shaped electrode connected to the distal end of the operation lever, and having a flange-shaped portion formed in the middle portion thereof, a cylindrical inner surface electrode insulated from the electrode, and the cylindrical inner surface electrode. The cylindrical bottom electrode provided in the bottom part of this is provided. By tilting the operating lever in the circumferential direction, the electrode is inclined in the cylindrical inner surface electrode. Then, the electrode is inclined, and the simple contact switch conducts by contacting the flange-shaped portion of the electrode and the cylindrical inner surface electrode. In addition, by moving the operation lever in the axial direction, the electrode is drawn out in the cylindrical direction of the cylindrical inner surface electrode. The electrode is pulled out, and the flange-shaped portion of the electrode and the cylindrical bottom electrode come into contact with each other so that the simple contact switch conducts. Thus, the simple contact switch is provided with the contact type switching element.

(See FIG. 1 and FIG. 2).

The operation of the picking device configured as described above will be described. First, the picking apparatus main body transmits a signal to the picking operation terminal corresponding to the component to be picked. The terminal for picking operation which received the signal notifies an operator of the picking target component. In this manner, the picking device notifies the operator of one or more kinds of parts required for assembling one product and the position of the parts, and instructs the picking timing.

When the worker finishes picking the parts, the operator operates the lever switch 200 of the picking terminal corresponding to the parts. The picking apparatus main body recognizes that all the parts are picked by receiving a response of the picking completion confirmation from all the picking work terminals corresponding to the parts that were the picking targets. When the parts are picked, the picking device main body is configured to shift to the picking operation of the parts for assembling the next product.

Next, the structure of the picking operation terminal which concerns on this embodiment is demonstrated, referring drawings. The terminal for picking work is mounted on a component shelf in which parts of a product to be assembled and manufactured are stored. This part shelf is a pipe rack woven by a pipe, for example. One picking terminal is assigned to each component (or one component group). A plurality of picking terminals are arranged on the parts shelf so as to correspond to the parts. The terminal for picking work which concerns on this embodiment is attached to the pipe rack partitioned by a pipe and a board | plate material for every component, and is attached to the pipe of the front end part which partitions a corresponding component. That is, the picking operation terminal is disposed above the corresponding component.

As shown in FIG. 1 and FIG. 2, the picking operation terminal which concerns on this embodiment is the instruction | indication means 100 which instruct | indicates a picking timing to an operator, and the lever switch 200 used to confirm that the said picking is completed. And a terminal body 300 to which the indicating means 100 and the lever switch 200 are mounted.

The instructing means 100 includes a notification means 110 for visually notifying the picking timing by displaying a light on to the worker, and a picking restriction means 120 for regulating the picking of the corresponding parts to the worker. In addition, the indicating means 100 may include only one of the notification means 110 and the peaking restriction means 120.

The fixture 320 is installed on the back side of the casing 310. Fixture 320 is disposed on the front surface of the pipe (P). Therefore, the fixture 320 may arrange the casing 310 so that the casing 310 does not interfere with the work when the worker takes out the parts.

Next, operation | movement of the picking operation terminal which concerns on this embodiment is demonstrated. First, when the picking operation terminal receives a signal indicating that the corresponding component is a picking target from the picking apparatus main body, the lamp 110 is lit and displayed, and the arms 121 and 121 are opened in the open position (two points in FIG. 2). The shutter 120 is opened by rotating the shutter 120 to a position indicated by a dashed line. And the picking operation terminal notifies the corresponding component and the position of the said component. In this way, the picking operation terminal prompts the picking to the worker.

When the worker finishes picking the parts, the operator operates the lever switch 200 of the picking terminal corresponding to the parts to confirm that the picking work is completed. The terminal for picking work which has been completed confirmation sends a response of the picking completion confirmation to the picking apparatus main body. The terminal for picking work which has received the response of completion confirmation from all the picking work terminals moves to the next picking work.

Next, the operation of the lever switch 200 when the operator operates the lever switch 200 of the picking work terminal will be described in detail. Further, the lever switch 200 according to the present embodiment can be switched by tilting the lever main body 210 of the lever switch 200 with respect to the support means 260 or by tensioning the support means 260. Can be. Therefore, the operation of each lever switch 200 in the tilting operation and the pulling operation will be described.

First, the case where switching is performed by tilting the lever main body 210 of the lever switch 200 with respect to the support means 260 is demonstrated with reference to FIG. 3 and FIG. In addition, in this embodiment, as shown to FIG. 1 and FIG. 2, about the example arrange | positioned so that the said free end of the lever main body 210 of the lever switch 200 may be perpendicularly downward with respect to the terminal main body 300. FIG. Explain. However, for example, the same is true for the case in which the free end of the lever body 210 of the lever switch 200 comes in the horizontal and horizontal direction with respect to the terminal body 300. That is, since the first lever member 220 of the lever body 210 of the lever switch 200 is supported by the supporting means 260, the lever body 210 is held in a tilted downward direction by its own weight. It is not to be done.

Before the lever body 210 of the lever switch 200 is operated (when the lever body 210 is in the standby position), as shown in FIG. 3, the disc portion 223 of the first lever member 220. ) Is pushed up toward the protruding portion 274 of the first support portion 270 by the pressing force of the elastic body 280. The disc portion 223 is in contact with the protrusion 274 over its entire circumference. The attitude | position of the lever main body 210 will be in the state along the center direction of the annular protrusion part 274. As shown in FIG. In this case, the magnet 251 installed at the front end of the first lever member 220 is positioned at a position opposite to the magnetic sensor 252 installed at the first support part 270, and the switching element 250 is turned on. It is.

When the lever body 210 of the lever switch 200 in the standby position is tilted, as shown in FIG. 4, the disc portion 223 of the first lever member 220 is applied to the pressing force of the elastic body 280. It is pushed up toward the projection part 274 by this. And the disc part 223 rotates the protrusion part 274 to the support point and resists the pressing force of the elastic body 280, making contact with the protrusion part 274 at one point, and the part of the protrusion part 274 other than a support point. Spaced apart. The posture of the lever main body 210 is inclined from the center direction of the annular projection 274.

At this time, the magnet 251 provided at the tip of the first lever member 220 also rotates the contact point between the protrusion 274 and the disc 223 to a support point, so that the magnet 251 is the first support part 270. The distance from the magnetic sensor 252 is installed in the spaced apart position, the switching element 250 is switched to the off state.

When the lever body 210 is opened from the tilting operation, the disc portion 223 of the first lever member 220 is pushed up toward the protrusion 274 by the pressing force of the elastic body 280 as a supporting point. And the disc part 223 returns to the state which contacts the protrusion part 274 over the whole periphery. The attitude of the lever body 210 is also returned to the state toward the center of the annular projection 274. In this case, the magnet 251 provided at the front end of the first lever member 220 is positioned at a position facing the magnetic sensor 252 provided at the first support part 270, and the switching element 250 is in an on state. Is switched to. By switching the switching element 250 to an on state, the completion confirmation of the picking operation is performed.

Next, the case where switching is performed by tensioning the lever main body 210 of the lever switch 200 with respect to the supporting means 260 will be described with reference to FIGS. 3 and 5. When the lever main body 210 of the lever switch 200 in the standby position is tensioned, as shown in FIG. 5, the disc portion 223 of the first lever member 220 is pressed by the elastic body 280. It is spaced apart from the protrusion 274 of the first support portion 270 while resisting. The disc portion 223 moves in parallel to the center direction of the annular protrusion 274. The attitude | position of the lever main body 210 will be in the state drawn out from the support means 260, toward the center direction of the annular projection 274. As shown in FIG. At this time, the magnet 251 provided at the tip of the first lever member 220 is at a position facing the magnetic sensor 252 provided at the first support part 270. However, the magnet 251 is spaced apart from the magnetic sensor 252, and the switching element 250 is switched to the off state.

When the lever main body 210 is opened from the tensioning operation, the disc portion 223 of the first lever member 220 is pushed up toward the protruding portion 274 by the pressing force of the elastic body 280. And the disc part 223 returns to the state which contacts the protrusion part 274 over the whole periphery. In addition, even when the tension direction of the lever main body 210 is shifted from the center of the axis of the lever main body 210 with respect to the center of the protrusion 274, the disc part 223 of the first lever member 220 is a guide part ( Guided by 224, it is returned to the state in contact with the projection 274 over the entire circumference. The attitude of the lever body 210 is also returned to the state toward the center of the annular projection 274. In this case, the magnet 251 provided at the front end of the first lever member 220 is positioned at a position facing the magnetic sensor 252 provided at the first support part 270, and the switching element 250 is in an on state. Is switched to. By switching the switching element 250 to an on state, the completion confirmation of the picking operation is performed.

As described above, according to the picking operation terminal according to the present embodiment, the switching element 250 is turned on when the lever main body 210 is in the standby position. When the tilting operation or the tensioning operation of the lever body 210 from the standby position, the switching element 250 is switched to the off state in conjunction with the operation of the lever body 210. In this way, the lever switch 200 is in the on state and the off state by the operation of the lever body 210 in which the disc portion 223 of the lever body 210 is inserted and supported by the support means 260 in the standby position. Switch. In this manner, even when used for the picking operation in which the lever switch is operated each time picking is completed, the picking terminal is switched on and off in a non-contact manner. For this reason, the picking terminal can be equipped with the durability which can be used for a long time.

In addition, the switching element 250 is turned on in a non-contact state by a positional relationship between the magnet 251 provided at the one end of the lever body 210 and the magnetic sensor 252 provided at the first support part 270. It is configured to switch the on and off state.

That is, by performing the tilting operation or the tensioning operation of the lever body 210 from the standby position, the position of the magnet 251 provided at the one end of the lever body 210 is displaced, The change in distance from the magnetic sensor 252 is detected by the magnetic sensor 252 as the change in the magnetic field from the magnet 251. The switching element 250 is comprised so that an on state and an off state may be switched by the change of this magnetic field, without contacting the magnet 251 and the magnetic sensor 252.

In addition, since the second support part 280 is supporting the part of the lever main body 210 toward the first support part 270 while supporting the lever main body 210, the lever main body 210 is turned to the off state or the tilting operation. Is performed while resisting the pressurization by the second support portion 280. When the lever main body 210 is released from the operation which resists the pressurization by this 2nd support part 280, the lever main body 210 is a disc part of the lever main body 210 by pressurization by the 2nd support part 280. As shown in FIG. 223 is operated to be displaced to the standby position, and is operated until the disc portion 223 contacts the first support portion 280. When the magnet 251 installed on the lever body 210 and the magnetic sensor 252 provided on the first support part 280 return to opposite positional relations, the switching element 250 causes the lever body 210 to stand by. It returns to the state it was in the position. Accordingly, the switching element 250 is configured to be switched to the off state in a non-contact manner, and the positional relationship between the on state and the off state is reliably switched.

In addition, the lever main body 210 resists an elastic force by the elastic body 280 while maintaining the positional relationship between the magnet 251 provided on a part of the lever main body 210 and the magnetic sensor 252 provided on the first support part 270. You can change it. For example, the positional relationship between the magnet 251 of the lever body 210 and the magnetic sensor 252 of the first support part 270 can also be changed by the tensioning operation of the lever body 210. In addition, by performing the tilting operation on the lever body 210, the positional relationship between the magnet 251 of the lever body 210 and the magnetic sensor 252 of the first support part 270 can be changed. Therefore, the picking operation terminal can provide a degree of freedom in the operation of the lever body.
