Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape-type article conveying device that intermittently conveys articles using a continuous tape.

[Prior Art] In recent years, various automatic assembly devices have been proposed in conjunction with factory automation, but these automatic assembly devices can quickly (and reliably and also cheaply) assemble articles (parts), etc. The technical issue is the supply.

In other words, - The conventional method of supplying parts to automatic assembly equipment, which is most popular in boat fishing, is to prepare a pallet for placing parts in consideration of the external shape, weight, material, etc. of the parts to be supplied.
A pallet system has been used in which parts are placed on the pallet in advance in an aligned state, the pallet is then transported to a predetermined position, and the parts are sequentially taken out and assembled from the pallet by an automatic assembly device. Although this pallet method can be applied to relatively large parts and has some effect, small parts such as screws are too small to be handled by the pallet method, and the quantity used is large. It was impossible to implement this pallet method.

Furthermore, even if a pallet were to be applied to small parts such as screws, it would be very difficult to place them on the pallet in the same direction as it would take a lot of man-hours.

In view of this problem, it is possible to store small parts such as screws separately in a container, vibrate the container to align the orientation of the parts, and feed them one by one in an aligned state. In some cases, a vibrating parts feeder method was used.

However, both the pallet method and the vibrating parts feeder method described above have the disadvantage that when feeding multiple types of articles, pallets or vibrating parts feeders, etc., must be prepared according to the external shape of each item. Ta.

Therefore, a cassette-type parts supply device that solves the above problems was proposed in ``Parts Supply Device'' published in Japanese Patent Application Laid-Open No. 60-48855. The parts were sandwiched and stored continuously. However, according to this proposal, the removal operation cannot be performed using a robot hand or the like provided in the parts assembly equipment, and the tape that can be repeatedly touched and separated has a limit number of times, and if the number of times is exceeded, the tape must be replaced. Furthermore, when the tape is wound onto a reel, the tape sags, making it impossible to reliably send the parts, and the presence or absence of parts is not detected. There were many problems such as the robot hand not being able to move.

Therefore, the applicant of the present application filed Japanese Patent Application No. 1-84881.8488.
2.84883.84884.84885, we have proposed a tape-type article conveyance device 1, which solves the problems of the above-mentioned JP-A-60-48855 r parts supply device and achieves fully automatic robot hand operation. is possible.

[Problem to be solved by the invention] However, the applicant's r tape type article conveying device j
According to the above, a control means connected to a main control device of a parts assembly device or a parts manufacturing device equipped with a robot hand controls the drive of each tape for picking and placing articles and controls the counting of articles.

[Examples] Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a basic principle diagram showing how a part P is stored (placed) or taken out (picked) on a tape. In FIG. 1, to explain the basic principle by which a part P can be transported or taken out by a tape, the transport tape 3
As shown in the figure, recesses 3a having internal dimensions slightly larger than the external dimensions (depth, width, height) of the component P are continuously provided at the same intervals, while near the recesses 3a there are Detection holes 4 through which light from a home position stop sensor 20 (described later) passes are bored at regular intervals. Pitch holes 3b are continuously drilled near both edges of the conveying tape 3 as shown in the figure, and the pitch holes 3b engage with a sprocket 12, which will be described later, to apply a driving force to the conveying tape 3. I'm trying to convey it.

3 Furthermore, by covering the part P set inside the recess 3a as shown in the figure, the cover tape 5 holds the part P set inside the recess 3a in the set position and removes the part P from the recess 3a. This is provided to allow the part P to be taken out.

That is, when the conveyor tape 3 and the cover tape 5 are moved in the direction of the arrow B indicated by the broken line in the figure, the part P manufactured by the molding machine is gripped and moved by the robot hand H, and the conveyor tape 3 is moved. After being set inside the recess 3a,
The cover tape 5 covers the upper surface of the component P and is wound up with a reel to be described later.

On the other hand, the transport tape 3 is moved in the direction of arrow A shown by the solid line in the figure, and the cover tape 5 whose direction is changed by the guide roller 17 which is rotatable around the stud 8 is also moved in the direction of the arrow A shown by the solid line. When the part P is being moved, the upper surface of the part P is successively moved by the robot hand H.
Since the part P is exposed to the outside, it becomes possible to take out the part P upward.

In order to accommodate or supply the parts P as described above, each tape is wound inside each reel described later, or the parts P are continuously accommodated and supplied by supplying the tape from each reel. I have to.

The cover tape take-up reel 8 drives the cover tape 5 in the direction of arrow A shown by the solid line, and
It is provided to wind up the cover tape 5 and to supply the cover tape 5 in the direction of arrow B shown by the broken line, and a motor described later is provided for driving. An actuator 25 is provided between the cover tape winding wheel 8 and the guide roller 17, which functions to prevent the cover cheese 5 from curdling and to detect the occurrence of curvature when the curvature exceeds an allowable range. It is being

The structure of this actuator 25 is such that a lever part 2 is rotatably held around a stud 8 and is rotated in the direction of arrow C from the position shown by the two-dot chain line to the position shown by the solid line.
5a, the lever part 25a is vertically installed at one end of the lever part 25a, and is rotated in the direction of arrow C from the position shown by the chain double-dashed line in accordance with the tensioned state of the cover tape 5 by contacting the back surface of the cover tape 5. The spring 26 is stretched between the arm lever 25b that moves to the position shown by the solid line, and the stud S and a hole 25d drilled in the corner of the other end of the lever part 25a.
and the detection section 24 that is shielded by the other end of the lever part 25a.
It consists of a chibutalumi detection sensor 24 equipped with a. The actuator 25 configured as described above is moved in the direction of arrow C to prevent crud from occurring on the cover tape 5, and when the crud exceeds the allowable range, it outputs a signal to indicate crud and causes the cover tape to wind up the reel. 8 winding drive is performed.

Next, FIG. 2 is a perspective view showing another configuration of the actuator 25, in which the direction of rotation of the actuator 25 is reversed, and the actuator 25 contacts the end of the lever part 25a to prevent further rotation. While a stopper 28 is provided to restrict the movement of the cover tape 5, the cover tape 5 is allowed to pass under a guide roller 27.

The other components are the same as those of the actuator 25 in FIG. 1, so they are omitted, but the actuator 25 is
5, the lever 7 portion 25a shields the detection portion 24a of the tape walnut detection sensor 24 when it is in contact with the stopper 28, thereby enabling more stable detection.

Again, in FIG. 1, between the guide rollers 17 and 27 there is an almost full warning sensor 22 and a low remaining warning sensor 23.
The detection marks 29 are provided facing each other so as to enter both ends of the cover tape 5 in the width direction, and the near-full warning sensor 22 detects the detection mark 29 printed or otherwise provided near the end of the cover tape 5. At the same time, the state of accommodation or supply of the parts P is detected by detecting the detection mark 30 near the end on the opposite side of the bar tape 5 with the low remaining quantity alarm sensor 23.

On the other hand, the origin position stop sensor 2 detects the aforementioned detection hole 4 at a position corresponding to the operation reference position of the robot hand H.
0 integrally includes a light emitting element 20a and a light receiving element 280b. A reflecting mirror 21 is disposed above the origin position stop sensor 20 with the conveying tape 3 interposed therebetween, and when the light beam emitted from the light emitting element 20a passes through the detection hole 4, the light beam is reflected by the reflecting mirror 21. As a result of being reflected back to the light receiving element 20b and detected, the position of the detection hole 4 is detected. Therefore, the cover tape 5 is made of a resin material that does not transmit light.

Next, FIG. 3 is a sectional view showing how the detection hole 4 is detected at a position corresponding to the operation reference position of the robot hand H. In this figure, a light beam emitted from the light emitting element 20a of the origin position stop sensor 20 passes through the detection hole 4, is reflected by the reflector 21, and travels from the position detected by the light receiving element 20b to the center position of the robot hand H. The distance is set, and this position is the robot hand H.
This is used as the origin position for picking and placing parts.

In FIG. 4, a reinforcing member (not shown) is integrally provided on the board 1, which is made from a plate material and processed to have the outline shown in the drawing. The substrate l has strength. On this board 1, a stud S indicated by the symbol S in the figure is installed vertically from a frame (not shown) that is integrally formed with the board 1, and allows the reel, wheel, etc. to rotate and pivot freely. I try to support them.

As described above, the transport tape 3 and the cover tape 5 with the component P set in the recess 3a are wound up by the component mounting reel 6 with the cover tape 5 covering the opening of the recess 3a as shown in the figure. For this purpose, the component mounting reel 6, the cover tape take-up reel 8 that takes up and supplies the cover tape 5, and the tape take-up reel 7 that takes up and supplies the transport tape 3, respectively. is rotatable around the stud S.

On the other hand, the tape ends of the rotation centers 6c, 7c, and 8c of these reels are fixed portions 6d, 7d, respectively.

In FIG. 5, while driving the various tapes mentioned above,
Rubber rollers 13b made of urethane rubber are attached to both ends of the output shaft of a motor 13a for generating tension in the tape. In order to make the outer peripheral surfaces of these rubber rollers 13b come into contact with the outer peripheral edges of the hubs 6a and eb of the component mounting reel 6 with biasing force, the motor 13a
As shown in the figure, the arm member 13c is provided at the tip of an arm member 13c which is rotatably supported around a stud 8 which is vertically provided from the base plate 1, so that the arm member 13c is in the abutment position shown in the figure.

Furthermore, a tension spring 13e is stretched between the other end 13d of this arm member 13c and the stud S.
A biasing force is applied to rotate the arm member 13c in a clockwise direction, and the outer circumferential surface of the rubber roller 13b is brought into contact with the outer circumferential edge of the hubs 6a and 6b of the component mounting reel 6 with a biasing force, thereby causing friction. I'm trying to drive it.

Again, in FIG. 4, wiring indicated by two-dot chain lines in the figure is connected to the control device 10 from the motors 13a, 143a, and 15a configured as explained based on FIG. The motors 13a, 14a, and 15a perform the driving described later.

This control device 10 is provided with a changeover switch 10a at a position that can be operated from the outside.
is used when switching the operation mode, which will be described later.

As shown in the figure, this control section 10 is built into a tape-type article conveyance device 50, and when set to an assembly device M or a parts manufacturing device N, which will be described later, a signal and a power line are connected to the assembly device M or a component manufacturing device N. It is automatically connected to the parts manufacturing equipment N.

Further, when the tape type article conveyance device 50 is set in the parts manufacturing device N or the assembly device M, the power is automatically turned on, and the operation mode switching performed by the above-mentioned changeover switch 10a is automatically performed. is also possible.

Next, the stepping motor 9 indicated by a broken line is connected to a control device 10 through wiring indicated by a two-dot chain line in the figure, and is driven by control from the control device 10. However, the rotational driving force of the stepping motor 9 is transmitted to the sprocket gear 12b of the sprocket 12, which is rotatable around the stud S, via the belt 11 shown in broken lines.

On the outer peripheral surface of this sprocket 12, bins 12a that engage with the pitch holes 3b of the conveying tape 3 are planted at equal intervals with the pitch holes 3b of the conveying tape 3.
can be conveyed by the rotational drive of the stepping motor 9. Two of these sprockets 12 are integrally constructed with a sprocket gear 12b, and are adapted to engage with two rows of pitch holes 3b of the conveying tape 3.

On the other hand, the aforementioned origin position stop sensor 20 is disposed near the right of these two sprockets 12, while a reflecting mirror 21 is disposed above this origin position stop sensor 20. Further, the nearly full warning sensor 22 and the low remaining warning sensor 23, which were explained based on FIG. 10. On the other hand, the tape walnut detection sensor 24, which is turned on and off by the rotational movement of the actuator 250, is also connected to the control device section 10.

Next, a guide roller 16 rotatably supported around a stud S on the substrate 1 changes the direction of transport of the transport tape 3 from the vertical direction toward the subrocket 12 as shown in the figure. It is set in.

Further, a guide roller 17 which is supported by a shaft in the same way as the guide roller 16 is provided in order to change the conveying direction of the cover tape 5 from the direction toward the sprocket 12 as shown in the figure to the direction toward the component mounting reel 6. It is being

Furthermore, as shown in the figure, the guide rail 18, which is provided on the substrate 1 and is formed by processing the plate material so as to form a circular arc, extends the conveying tape 3 and the cover tape 5 covering the conveying tape 3 into a circular arc. It is provided for guiding along the outer periphery of the In addition, a pair of cam followers 19 rotatably supported around studs S near the left and right ends of the base l are attached to an assembly device M or a parts manufacturing device N, which will be described later, to assemble the entire tape-type article conveyance device 50. It is used as a guide for relative positioning when certifying.

Next, FIG. 6 is an external perspective view showing how the tape-type article conveying device 50 is set in the assembly device M equipped with the robot hand H, and FIG. 7 is a parts manufacturing device equipped with the robot hand H. FIG. 5 is an external perspective view showing how the tape-type article conveying device 50 is set on the N. In both FIGS. 6 and 7, guide guides are used for relative positioning after the tape type article conveying device 50 is set and inserted into the mounting section 32 fixed at a predetermined position of the assembly device M or the parts manufacturing device N. As a result, the pair of cam followers 19 fall into the locking grooves 32a of the mounting portion 32 and are set at a predetermined position.

Each of these assembly devices M or parts manufacturing devices N is provided with a robot hand H, and the movement of the robot hand H is completely synchronized with the stepping motor 9 of the tape-type article conveying device 50, so that the parts manufacturing device The part P manufactured by the device N is placed in the recess 3a of the transport tape 3, while the part P is picked by the assembly device M when the part P is stored in the recess 3a of the transport tape 3. There is.

Next, FIG. 8 is a block diagram of a schematic configuration of the tape type article conveying device 50, and the configuration of the tape type article conveying device 50 in this figure is connected to the control device 10 having the configuration described based on FIG. The components and elements already explained in FIG. 4 are given the same numbers and symbols as in FIG. 4, and their explanations are omitted. In FIG. 8, the motors constituting the drive assembly 13, 14, 15 and the stepping motor 9, respectively, and the stepping motor each have a motor driver connected between the control device 10 and generating voltage and current for driving. It is connected. An alarm device A is further connected to the control device 10 to notify the operator of the occurrence of an abnormality. Further, the optical connector C2 and the power connector C3, which are optically coupled to the central control device 100 of the parts manufacturing device N or the assembly device M, and which exchange signals and supply power, are connected to the control device 100, respectively.
It is connected to the.

The operation of the tape type article conveying device 50 having the above configuration will be explained based on the operation flowcharts shown in FIGS. 9 and 10.

First, the flowchart of FIG. 9 shows an operation mode in which the parts P manufactured by the parts manufacturing apparatus N are accommodated on the conveying tape 3. The conveying tape 3 is fully wound up by the tape winding reel 7, and the cover tape 5 is also fully wound by the cover tape winding reel 8. This state is basically after the detection mark 30 provided near the end of the component mounting reel 6 of No. 5 has been detected by the low quantity alarm sensor 23.

Therefore, the component mounting reel 6 is in an empty state, and the transport tape 3 is placed on the rotation center 6C of the component mounting reel 6.
Only the overlapping ends of the cover tape 5 and the cover tape 5 are fixed. Now, in this state, when set in the parts manufacturing apparatus N, switch 1 of the control section 10
0a is automatically set to the storage side or manually set.

Next, proceeding to step S1, the origin position stop sensor 20
The on/off state of is determined, and when the on state is determined and it is determined that the conveying tape 3 is at the origin position,
Proceeding to step S6, the central control device 1 of the parts manufacturing apparatus N
00 that parts placement is possible. Therefore,
Proceeding to step S7, the part P is placed in the recess 3a of the transport tape 3 by the robot hand H provided in the part manufacturing apparatus N. After this accommodation, in step S8, when the control device 10 receives a communication from the central control device 100 indicating the completion of accommodation, the process proceeds to step S2.
In order to advance the conveying tape 3 and the cover tape 5 in the direction of the dashed arrow B in FIG. The drive is then stopped to allow the next part to be placed.

In the following step S3, the on/off state of the almost full alarm sensor 22 is determined. If it is determined that the OFF state is determined and it is determined that the conveying tape 3 has not yet reached the end, the process proceeds to step S6 described above, where parts placement is performed. will be carried out. Thereafter, the operations of steps S2, S6, S7, and S8 are repeated until the component mounting reel 6 is full.

When the component mounting reel 6 is almost full, the detection mark 29 of the cover tape 5 whose end is fixed to the cover tape take-up reel 8 is detected by the near-full warning sensor 22.
As a result of the detection, the on state is detected in step S3.

When this ON state is detected, the process proceeds to step S4, and the central controller 100 is notified of the nearly full warning sensor 2.
2, it is communicated that the detection mark 29 on the cover tape 5 has been detected.

After this, the process proceeds to step S5, where a nearly full warning (3) is output, and a bridle warning is issued to notify the operator that the placement of the part P is almost over. Before and after this alarm, subtraction from the remaining number of concave portions 3a of the transport tape 3 in (2) is performed for each place of the part P. Step S5
When the remaining number of concave portions 3a of the transport tape 3 reaches zero in step (3), an abnormality alarm at the main end is issued to notify the operator that the placement of the part P has been completed, and the parts manufacturing equipment N is turned off. The placing operation of the robot hand H is completed and stopped.

In this way, the parts P are directly placed from the parts manufacturing apparatus N.

Next, when the component mounting reel 6 is fully wound up, the tape type article conveying device 50 is removed from the component manufacturing machine N, and the robot hand H shown in FIG. The cam follower 19 of the tape type article conveying device 50 is guided and set in the assembly device M equipped with the following.

Next, the switch 10a of the control unit 10 is automatically or manually set to the supply side.

Thereafter, each of the drive assembly 14.15 and the stepper motor 9 are rotated, resulting in each of the component loading reel 6, the cover tape take-up reel 8, the tape take-up reel 7, and the sprocket wheel 12 being rotated. The robot hand H moves each tape in the direction of the solid arrow shown in FIG. ing.

The flowchart in FIG. 10 shows a one-work mode in which the parts P to be assembled by the parts assembling apparatus M 5 are picked from the transport tape 3. In FIG. 10, when the part assembly device M is set, the switch 10a of the control unit 10 is automatically set to the pick side or manually set.

Next, proceeding to step Sl, the origin position stop sensor 20
The on/off state of is determined, and when the on state is determined and it is determined that the conveying tape 3 is at the origin position,
Proceeding to step S6, the central control device 1 of the parts assembly device M
00 that it is possible to pick parts. Next, the process proceeds to step S7, where the robot hand H provided in the component assembly device M picks the component P from the recess 3a of the transport tape 3. After this pick, step S
At step 8, when the control device 10 receives the communication from the central control device 100 indicating that the removal is complete, the control device 10 proceeds to step S2 and drives the transport tape 3 and the cover tape 5 in the direction of the solid line arrow A in FIG. Assembly 14.
15 and the stepping motor 9 are rotated and driven until the origin position stop sensor 20 is turned on, and then the driving is stopped and the parts are placed in a position where the next component can be picked.

Here, the drive control of the drive assembly 15 is performed by an actuator 25.
If the chip sagging detection sensor 24 that detects the rotation of the guide tape 5 is turned off and the guide tape 5 is crooked, the drive assembly 15 is rotated clockwise to remove the guide tape 5. Tension is always applied to the

In the following step S3, the remaining quantity alarm sensor 23
If it is determined that the conveying tape 3 has not reached the end yet, the process proceeds to step S6, where parts picking is performed.

Thereafter, the operations of steps S2, S6, S7, and S8 are repeated to reel parts mounting reels 6 to 61! Pick item P.

When the number of parts mounting reels 6 remaining decreases, the detection mark 30 of the cover tape 5 whose end is fixed to the cover tape take-up reel 8 is detected by the remaining quantity alarm sensor 23.
As a result of the detection, the on state is detected in step S3.

When this ON state is detected, the process proceeds to step S4, and the central control device 100 is notified of the low remaining quantity alarm sensor 23.
This communicates that the detection mark 30 on the cover tape 5 has been detected. After this, proceed to step S5■
It outputs a warning that the number remaining is low and issues a bridle warning to notify the operator that the end of picking the part P is near. Around the time of this 8 alarm, subtraction from the registered remaining number N of concave portions 3a of the conveying tape 3 in (2) is performed every time a component P is picked. In step S5 (■), when the registered remaining number N of the concave portions 3a of the transport tape 3 becomes zero, this time an abnormality alarm of the main end is issued to inform the operator that the picking of the part P has been completed, and also to assemble the part. The picking operation of the robot hand H of the device M is completed and stopped.

In this way, the parts P are picked from the tape-type article transport device 50 to the parts assembly device M.

Thereafter, by repeating the above operations, the parts P manufactured by the parts manufacturing apparatus N are supplied to the assembly apparatus M. Here, if a large number of tape-type article conveyance devices 50 are prepared, the operating rate of the assembly device M and the parts manufacturing device N can be increased.

In the above embodiment, the control section 10 is incorporated in the tape-type article conveyance device 50, and the signal line 9 is automatically connected when it is set in the assembly device M and the parts manufacturing device, but it does not function independently. Anything you do is fine.

As explained above, by conveying the assembled parts using a tape provided with a recess that matches the shape of the assembled parts, it becomes possible to accurately position the assembled parts when installing and taking them out. Furthermore, robots and the like have made it easier to automate the transportation and supply of small articles, which was previously quite difficult.

Also, the conveyor tape and cover tape should be placed on M2 (
Since the tape can be wound up, it can be reused semi-permanently, eliminating the need to replace the tape and significantly reducing running costs.

Furthermore, in addition to the stepping motor 9 for driving and the rotation assembly 13, 14.15, an actuator 25 is also provided.
Since the tape walnut detection sensor 24 which is activated by the tape walnut detection sensor 24 is used, troubles such as mistakes in tape winding due to tape bending or falling parts P, etc., almost no longer occur.

Furthermore, the tape drive section can be installed outside the tape type article conveyance device 50 and used in common.

In the above embodiment, the part P is a rectangular parallelepiped, but if the recess 3a of the conveying tape 3 is formed to allow accurate positioning of the part P, it can also be used for parts with complex shapes. Needless to say. Further, instead of the detection hole 4, a corner portion of the bottom surface of the recess 3a may be detected, or a reflective tape may be provided instead of the detection hole 4, so that the reflecting mirror 21 is omitted.

[Effects of the Invention] 1. As explained above, according to the tape-type article conveying device of the present invention, the tape-type article conveying device of the present invention can perform drive control of each tape for picking and placing articles and controlling article counting.
The tape type article conveyance device can be constructed at low cost.

Furthermore, a tape-type article conveyance device that can be automatically started up after power is turned on can be constructed at low cost.
