JP6203581B2 - Individual take-out device for irregularly shaped parts stocked in an unassembled state - Google Patents

Description

  The present invention treats, for example, deformed parts whose shapes are difficult to align, such as fastening bolts for machine parts, wood materials, tapping screws for fastening sheet metal materials, and clips for fastening boards, etc. The present invention relates to an individual take-out device for irregularly shaped parts stocked in a non-aggregate state, which is individually taken out from the collective state.

  Bolts, tapping screws, clips, etc. have a head that protrudes in an umbrella shape or a crown shape with respect to the pin-shaped part, and the pin-shaped part is provided with a helical screw thread or an inverted tooth-like engagement. It has a shape with a fold. Incidentally, a component having such a shape is hereinafter referred to as a “deformed component” in the present specification. Of course, when such deformed parts are simply assembled, their orientations are not uniform, that is, they are in an unaligned state, and the spiral threads and the like are intertwined. For this reason, in order to take out such deformed parts from the state of being bulk stocked, it is possible to manually pick up and take out, but to make sure that such work is taken out one by one with a mechanical device, It is quite difficult.

  Of course, a device that takes out the leading parts one by one while aligning the deformed parts with the seismic feeder is also widely used. However, this type of apparatus is provided so as to match and synchronize with the overall movement of the assembly line, and is suitable for the case where it is sent to the next process in the process of producing bolts exclusively. However, in the process of preparing completed bolts etc. at the assembly site etc., the assembly work position can be switched for each product, and the required number per tact is prepared by the operator. In other words, the above-mentioned shaking feeder is unsuitable as a supply form in which small turning is effective. In particular, when the shape of the object to be handled is not constant due to the shape of the object being a deformed part, there are almost no supply devices that can accept these for general use. Also, many attempts to move deformed parts are based on the premise that they are first aligned, and do not directly transfer and take out deformed parts that are in a completely unassembled state (prior art). Reference 1).

JP 2001-277145 A

  The present invention has been made in consideration of these various backgrounds, and even various types of deformed parts are universally accepted, reliably removed, and necessary for necessary work processes. This is an attempt to develop a new device for taking out irregularly shaped parts stocked in a non-aggregated state, which can be used in a number of ways.

  The mode for carrying out the present invention includes an embodiment described below, and includes various improved embodiments based on this technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments.
The irregularly shaped individual take-out device M of the present invention is provided with a work stocker 2 with respect to an appropriate frame 1, and further reciprocates oppositely to the push-out plunger 3 that reciprocates below the work stocker 2 and the push-out plunger 3. The receiving nozzle device 4 is provided, and the relay conveying device 5 and the supply setting device 6 are further provided as auxiliary members.
Hereinafter, the individual take-out device M for odd-shaped parts will be described as an individual take-out device M.

First, the individual take-out device M supports the frame 1 on a machine base T on an appropriate table. As an example, the frame 1 is formed as a substantially rectangular tube-shaped housing frame 10 having an open top, and the housing frame 10 is supported by a support frame 11 provided on the machine base T so that the angle can be freely set. ing. That is, first, bracket-like connection frames 12 are provided on the left and right sides below the center of the housing frame 10.
On the other hand, the support frame 11 is formed with an adjustment screw hole 13 formed as an arc-shaped elongated hole above the support frame 11 so that the set angle of the housing frame 10 can be adjusted by appropriate bolting. Incidentally, this adjustment angle can be set to an angle of about 30 degrees to 45 degrees from the horizontal state. In addition, regarding the housing frame 10 constituting the frame 1, various subframe-like members, working spaces, and the like are further formed, and these will be described in relation to them in the description of other members. Explain each time.

Next, the work stocker 2 attached to the housing frame 10 of the frame 1 will be described. The workpiece stocker 2 is a member that accommodates the workpiece W in an unassembled state, and has a hopper shape with an upper opening. First, the upper portion is a large opening 20 and a lower outlet 21 is provided. This take-out port 21 is formed by opening a side wall surface on the extrusion surface side of the work W below the work stocker 2. On the other hand, the bottom of the work stocker 2 is closed by a work guide rail 22 as shown in FIGS. 3 and 4, and the work guide rail 22 is connected to the lower surface of the work stocker 2 in the front-rear direction. It is arranged.
A push plunger 3 to be described later is configured to reciprocate along the work guide rail 22. The work guide rail 22 has a substantially inverted W-shaped cross section, and forms a central guide portion 22a having a recessed shape so as to guide the push-out plunger 3 in the central portion, and both side portions thereof. Constitutes an exclusion inclined surface 22b. A front adjustment plate 21a is provided in front of the take-out port 21 in the take-out direction so that the open state of the take-out port 21 can be set. A rear adjustment plate 21b is also provided at the rear.

Next, the extrusion plunger 3 that reciprocates near the bottom of the work stocker 2 will be described.
The drive source of the pusher plunger 3 is a push cylinder 30 which is attached to an appropriate cylinder bracket fixed to the housing frame 10. The plunger body 31 is fixed to the cylinder rod 30a of the extrusion cylinder 30, and the tip of the plunger body 31 is shaped so as to be somewhat recessed, and has a catching recess 32 for ensuring the catching of the workpiece W. .
As for the movement range of the pusher plunger 3, the position indicated by P0 is the initial position of the pusher plunger 3, that is, the pusher plunger origin P0, and the position indicated by P1 is the position where the pusher plunger 3 is most pushed out, that is, the push plunger. The top dead center P1.

Next, the receiving nozzle device 4 will be described.
The receiving nozzle device 4 is supported with respect to a nozzle mount frame 16 provided so as to span the housing frame 10. A shift cylinder 40 for shifting the entire receiving nozzle device 4 is supported on the nozzle mount frame 16 so as to be mounted thereon. The cylinder rod 40a of the shift cylinder 40 is connected to a nozzle holder 41, and the nozzle holder 41 is a generic name for a member that supports a nozzle including a holding arm 42, a nozzle guide rod 43, and a connecting plate 44. Is. First, the holding arm 42 that is one of the constituent members of the nozzle holder 41 will be described. This is a member that is bent in opposite directions so that it can be expressed as a crank shape in a side view with sufficient strength, One end portion constitutes a rod receiving portion 42a connected to the cylinder rod 40a, and the other end is a guide rod receiving portion 42b. As shown in FIG. 5, the guide rod receiving portion 42b is provided with a pair of slide guides 42c for smoothly guiding the nozzle guide rod 43 on the left and right sides as viewed in the slide guide direction. A pair of nozzle guide rods 43 are slidably supported by the pair of slide guides 42c. A receiving nozzle 45 is provided at the center of the connecting plate 44 that connects the nozzle guide rods 43. Retained.

  Hereinafter, the receiving nozzle 45 will be described. The receiving nozzle 45 has a suction port at the tip, and includes, as an example, a nozzle pipe 451, a mouth pipe 452 at the tip, and a suction hose 453 extending to the other end of the nozzle pipe 451. . The mouth pipe 452 is preferably a flexible and deformable member that can easily receive the workpiece W. However, the mouth pipe 452 may be a hard member that does not undergo such deformation, or the nozzle pipe 451 does not include this. It is good also as a suction port directly at the tip. Further, the receiving nozzle 45 supported by the connecting plate 44 can be moved on the same movement line as the pushing plunger 3 by the holding arm 42 in the nozzle holder 41. Here, since the nozzle guide rod 43 is slidable with respect to the slide guide 42 c in the holding arm 42, the nozzle guide rod 43 can be operated so as to protrude to a certain position and remain at that position despite the extension of the shift cylinder 40. . That is, even when the cylinder rod 40a of the shift cylinder 40 is sufficiently extended and the mouth pipe 452 of the receiving nozzle 45 comes into contact with the catching recess 32 at the tip of the push plunger 3 via the workpiece W, A movement is ensured such that the nozzle guide rod 43 retreats in a shock-absorbing manner. Regarding the operating area of the receiving nozzle 45, the initial standby position is the receiving nozzle origin S0, the position where the receiving nozzle 45 is projected most is the receiving nozzle bottom dead center S1, and the range in which the workpiece W is received is the receiving nozzle operating zone Sz.

  Next, the suction hose 453 will be described. In this case, the receiving nozzle 45 for sucking and holding the workpiece W by the receiving nozzle device 4 is connected to the vacuum mechanism. As an example, this vacuum mechanism is an ejector 455 that operates by using a jet of a compressor installed in a factory or the like, and in addition to a vacuum suction action as employed in a general ejector mechanism, Further, the operation up to slight air discharge is performed. In addition, a suction detection sensor switch 456 that can detect a change in suction negative pressure is provided in the middle of this, and this is digitally controlled as appropriate to detect the presence or absence of suction negative pressure, and by the ejector 455. It also serves as a switch function that shuts off the suction state.

  Here, the portion where the push-out plunger 3 and the receiving nozzle device 4 face each other, that is, the vicinity of the center of the housing frame 10 is the capture space 10S shown in FIG. 6A, and this portion is the receiving nozzle. It overlaps considerably with the operating zone Sz. This part is provided with a workpiece presence / absence sensor 17 to which a photoelectric switch or the like for detecting whether or not there is a workpiece W captured by the mouse pipe 452 in the receiving nozzle 45 is provided.

Next, the detailed operation state will be described later, but the workpiece W individually taken out in the housing frame 10 is further transferred to a necessary supply location or the like by the relay transfer device 5 as appropriate. The relay transport device 5 employs a configuration in which the relay hopper 51 faces the take-out hopper 15 in the housing frame 10 and a transport box 52 is provided below the relay hopper 51. Note that a chute plate 52a is provided in the transport box 52 for biasing the dropped workpiece W toward the delivery direction as appropriate, and an air nozzle 53 is provided.
In addition, the transport box 52 has a hose joint 54 that can be connected to a hose having a circular cross-section by narrowing down a portion opposite to the air nozzle 53, and includes a transport hose 55 at the tip. The air nozzle 53 is configured to blow out air from an air compressor installed in the factory.
Of course, in order not to waste the compressed air of the air compressor, it is preferable that the ejection is stopped each time the workpiece W is detected to be dropped. The other end side of such a conveyance hose 55 reaches the supply setting device 6.

The supply setting device 6 will be described below. In this case, the transfer hose 55 is connected to the upper surface of the take-in box 61, while the bottom plate 62 of the take-in box 61 is provided with a drop hole 62 a.
Further, a bottom shutter 63 is slidably provided on the upper surface of the bottom plate 62 so as to overlap. The bottom shutter 63 includes a shutter hole 63a having substantially the same shape as the drop hole 62a, and is slide-shifted by a shift actuator 64 using an air cylinder, an electromagnetic plunger, or the like.
The bottom shutter 63 always stands by in a state where the shutter hole 63a does not match the drop hole 62a of the bottom plate 62, and in this state, the bottom shutter 63 acts to hold the work W transferred to the take-in box 61 therein. .
On the other hand, when the workpieces W are taken out one by one or after collecting a predetermined quantity, the bottom shutter 63 is driven by the shift actuator 64 so that the shutter hole 63a and the drop hole 62a are aligned with each other, thereby taking in the take-in box 61. The work W received at the bottom of the machine is dropped onto the service tray 65 below the work W and supplied near the operator's hand.
It should be noted that various program forms can be used for other shift forms, automatic take-out for each number, and corresponding operation when inappropriate take-out is performed. This will be described later in the description of the operating state.
The movement of the bottom shutter 63 by the shift actuator 6 4 for taking out the workpiece W is detected by the limit switch 66.

The present invention comprises the above-described constituent members, and the operation mode of this will be described below.
<1. Initial state>
First, in the initial state, as shown in FIGS. 6-1 (a), (b), and FIG. 7, the workpiece W, which is a deformed part, is stocked in a bulk stock state, that is, in an unassembled state.
On the other hand, in the push-out plunger 3, the cylinder rod 30a of the push-out cylinder 30 is in the most contracted state. Therefore, the position of the catch recess 32 at the tip of the plunger main body 31 is generally opposite to the outlet 21 of the work stocker 2. Waiting at a position near the wall. In this state, the point at which the catching recess 32 at the tip of the plunger main body 31 faces is the extrusion plunger origin P0.
In the receiving nozzle device 4 as well, the cylinder rod 40a of the shift cylinder 40 is in a contracted state, so that the nozzle guide rod 43 supported by the holding arm 42 also stands by at the position farthest from the opposing push plunger 3. ing. As a result, the receiving nozzle 45 supported by the nozzle guide rod 43 is also waiting at the receiving nozzle origin S0 which is the position farthest from the pushing plunger 3. In practice, the housing frame 10 is installed with an inclination and the receiving nozzle device 4 side is arranged upward. Therefore, the receiving nozzle 45 in the receiving nozzle device 4 has its own weight and the handling of the suction hose 453. It stands by in a state where it is lowered most by a moderate elastic force due to the direction of the shin. That is, the nozzle guide rod 43 is set in a state of protruding toward the capturing space 10S.

<2. Individual pick-up operation status>
[Step 1]
First, when a start is instructed by an appropriate switching operation, the pushing plunger 3 and the receiving nozzle device 4 start operating almost simultaneously. That is, in the pushing plunger 3, when the housing frame 10 is inclined, the cylinder rod 30a of the pushing cylinder 30 extends from below, so that the plunger main body 31 passes through the bottom of the work stocker 2, It moves so as to further protrude from the outlet 21 and rise. By this movement, the catching recess 32 in the plunger main body 31 reaches the top dead center P1 of the pushing plunger while pushing out some of the workpieces W that have been thrown into the workpiece stocker 2 (FIG. 6-1 (c), FIG. 7). Incidentally, at this time, although several workpieces W are initially pushed up by the plunger main body 31, the workpiece W that is not accurately captured by the capture recess 32 is displaced from the inclined inclined surface 22 b of the workpiece guide rail 22 by the slipping outlet 21. Move back to the surroundings.
On the other hand, the receiving nozzle 45 in the opposite receiving nozzle device 4 starts suction of the suction hose 453 by appropriate program control, and the receiving nozzle origin S0 moves downward as the cylinder rod 40a extends in the shift cylinder 40. Extends (descends) toward the capture space 10S.

[Step 2]
If this state continues, the workpiece W that has been caught in the catching recess 32 of the pusher plunger 3 comes into contact with the receiving nozzle 45 that descends from above. In other words, at the receiving start point S, the workpiece W is sandwiched between the catching recess 32 at the tip of the plunger body 31 in the pusher plunger 3 and the mouth pipe 452 of the receiving nozzle device 4. Depending on the material, the mouth pipe 452 in the receiving nozzle 45 is preferably made of a flexible material so that it can follow the shape of the workpiece W to some extent.
At this time, the extruding plunger 3 and the receiving nozzle device 4 sandwiching the work W do not immediately receive the work W during this time, but until the plunger main body 31 in the extruding plunger 3 returns to a certain degree of lowering. continue.
That is, when the positional relationship between the position of the catching recess 32 in the push-out plunger 3 and the receiving nozzle 45 is viewed, one of the positions until the position of the catching recess 32 reaches the top dead center P1 of the push-out plunger as shown in FIG. The receiving nozzle 45 on the side in contact with this is located above the receiving nozzle bottom dead center S1.
Accordingly, when the receiving nozzle 45 comes into contact with the workpiece W lifted to the top dead center as shown in FIG. 6D, the receiving nozzle 45 is involved in the extending operation of the cylinder rod 40a of the shift cylinder 40. No further progress is possible. In other words, the nozzle guide rod 43 held in a floating state moves upward in the slide guide 42 c, and the receiving nozzle 45 moves together with the nozzle guide rod 43 so as to retreat apparently with respect to the moving direction of the nozzle holder 41. Then, the workpiece W is held between the catching recess 32 and the receiving nozzle 45 in the extruding plunger 3 for a while between the receiving nozzle bottom dead center S1 after passing through the extruding plunger top dead center P1. I keep doing it. In this state, when the suction detection sensor switch 456 detects a subtle change in vacuum pressure, it recognizes that the detection result holds the workpiece W, and both the plunger body 31 and the receiving nozzle 45 in the push-out plunger 3 Return to the home position.
The fact that the change in the vacuum pressure is maintained in the state where the origin position is restored automatically means that the work W is held in the mouth pipe 452 of the receiving nozzle 45 as an event in the apparatus. Be recognized.
If no subtle pressure change of the nozzle occurs, it indicates that the workpiece W is not captured by the mouth pipe 452 of the receiving nozzle 45, so that the operation returns to the original position and the operation of step 1 is performed.

[Step 3]
On the other hand, in a situation where the workpiece W is held on the mouth pipe 452 of the receiving nozzle 45, the workpiece presence / absence detection sensor 17 provided on the frame 1 near the receiving nozzle origin S0 detects the presence of the workpiece W. When both the output of the workpiece detection signal of the workpiece presence / absence detection sensor 17 and the pressure change data of the suction detection sensor switch 456 are obtained, it is determined that the workpiece W is reliably captured by the mouse pipe 452 ( Fig. 6-2 (e)).
Of course, judging the capture state of the workpiece W based on the AND state of these two sensor outputs is useful for improving the certainty. However, it is also possible to capture and judge in the OR state of one of these two sensor outputs and proceed to the next process.
After the determination of the workpiece capture is automatically made in the apparatus, the suction of the suction hose 453 is stopped to take out the workpiece W individually as shown in FIG. The workpiece W that has been lost loses its suction support, falls downward, and falls from the take-out hopper 15 to the relay conveyance device 5.
When the ejector 455 is used, it is possible to perform the blowing action instead of the suction action by switching the circuit. Therefore, when dropping the workpiece W, it is possible to stop the suction. It can also be performed more reliably.

[Step 4: Relay transport]
In this way, the workpiece W that has fallen on the relay conveyance device 5 falls into the conveyance box 52 as shown in FIGS. 6-3 (g) and 7, and along with detection data from the workpiece detection sensor, The compressed air is ejected from the air nozzle 53 only at a necessary timing, the work W is transported by the transport hose 55, and is supplied to the supply setting device 6 set at an appropriate use position.

[Step 5: Individual supply of workpieces]
The workpiece W sent from the transfer hose 55 of the relay transfer device 5 is temporarily stored in the take-in box 61 of the supply setting device 6 as shown in FIGS. 6-3 (h) (i). At this time, for example, if some required number is set in the assembly process, the number is counted, and when it is confirmed that the number is stocked in the take-in box 61, the bottom shutter 63 is opened. Then, it is dropped from the drop hole 6 2 a to the lower service tray 65 or the like. This position is a position where an operator or a work robot can easily pick it up directly. Whether or not a predetermined number has been sent is confirmed by, for example, counting the number of operations of the workpiece presence / absence detection sensor 17.
Of course, the bottom shutter 63 may be automatically actuated by the shift actuator 64, or a buzzer or the like notifies that the work W has been taken out in a fixed amount, and the operator manually operates the bottom shutter 63 accordingly to move the work W. You may take it out.
In this case, if an error occurs in the manual take-out operation, that is, if the bottom shutter 63 is opened when the predetermined quantity is not reached, a warning sound is generated or all operations of the individual take-out device M are stopped. Or you may.
When the bottom shutter 63 is shifted in the opening direction, the limit switch 66 is pressed, and the limit switch 66 outputs a signal for operating the individual take-out device M again.

[Other embodiments]
The present invention is based on the embodiment described above as one basic technical idea, but the following modifications can be considered. That is, the nozzle guide rod 43 is slid by its own weight so that the receiving nozzle device 4 of the present invention can follow the pushing plunger 3 in a follow-up manner. Since this is an action of utilizing gravity due to the case frame 10 being inclined, depending on the nature of the workpiece W, for example, the case frame 10 may be arranged substantially horizontally and gravity drop may not be obtained. In such a case, for example, as shown in FIG. 8, it is possible to adopt a configuration in which a floating spring 46 is provided at a portion of the nozzle guide rod 43 so that the receiving nozzle 45 is always protruded or has a fixed position position standby tendency. .
