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.

[Conventional technology 1] In recent years, various automatic assembly devices have been proposed in conjunction with factory automation, but these automatic assembly devices are capable of supplying the articles (parts) to be assembled quickly, reliably, and furthermore cheaply. This is the technical issue.

In other words, the conventional method of supplying parts to automatic assembly equipment, which is the most popular JIQ method, is to prepare a pallet for placing parts in consideration of the external shape, weight, material, etc. of the parts to be supplied, and to place the parts on the pallet in advance. A pallet system has been used in which parts are placed on the pallet in an aligned state, the pallet is then transported to a predetermined position, and parts are sequentially taken out and assembled from the pallet by an automatic assembly device. Although this pallet system can be applied to relatively large parts and has some effect, small parts such as screws are too small to be handled using the pallet system, 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 system that solves the above-mentioned problems has been proposed in JP-A No. 60-48855, r-component supply device A. In the present application, parts are continuously housed in a cassette as shown in the external perspective view of FIG. 9 (however, in the present application, FIG. 4).

That is, in FIG. 9, three studs S are suspended from the inner surface of the cassette case 100 shown by the two-dot chain line, and the reels 103, 1 are installed around these metals 988.
05 and 104 are provided so as to be rotatable and to obtain a driving force, respectively, and the belt 101 and the belt 102, which can be bonded together or brought into contact with each other a plurality of times, are wound up into a reel 103. It is configured to be retained.

In this cassette 100, articles 109 to be conveyed are sandwiched in advance between belts 101 and 102, and are continuously supplied and sent to reel 103.

Next, by rotating the take-up reels 1.04 and 105, the belts 101 and 1.02 are moved to the rollers 1 and 1, respectively.
06, 1, 107, 108, but the adhesive state of the belts 101, 102 is peeled off in the middle of the winding.
Since the sandwiched part 109 appears outside, the part 109 is taken out and assembled using a robot hand or the like. Furthermore, the number of parts was not detected.

[Problems to be Solved by the Invention] However, in the conventional cassette format described above,
Since the parts are simply held between the tapes, it is not possible to accurately position the parts on the tape, and as a result, the parts cannot be taken out using robot hands, etc. installed in the parts assembly equipment, and the tape can be repeatedly attached and separated. There is a limit number of contact and separation 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 becomes deflected, making it impossible to send parts reliably. There was a problem that the robot hand could not operate fully automatically because the number of parts was not detected.

Therefore, the tape-type article conveyance device of the present invention has been made in view of the above-mentioned problems, and its purpose is to enable accurate positioning of articles on the tape and to allow the articles to be handled by a robot device or the like. There is no need to replace the tape, and there is no bending in the tape when winding it up, so items can be transported reliably, the number of parts can be detected, and fully automatic robot hand movement is possible. An object of the present invention is to provide a tape-type article conveying device that enables the following.

[Means and Effects for Solving the Problems] In order to solve the above-mentioned problems and achieve the purpose, the tape-type article conveying device of the present invention uses a conveying tape formed with a plurality of continuous recesses for accommodating and conveying articles. a cover tape that covers the opening of the concave portion of the transport tape; a first reel that fixes respective ends of the transport tape and the cover tape and simultaneously winds the transport tape and the cover tape; a second reel that fixes an end of the transport tape and winds only the transport tape; a third reel that fixes an end of the cover tape and winds only the cover tape; and a third reel that winds only the cover tape with the end of the cover tape fixed.
a drive assembly that rotates the reel, a second reel, and a third reel in predetermined rotations, respectively; an intermittent drive means that engages with a continuous guide hole bored in the conveying tape and drives the conveying tape intermittently; a control means for controlling and driving the drive assembly and the intermittent drive means; an opening surface for taking out and storing the articles housed in the recess of the conveying tape; and a control means provided near the opening surface for controlling the presence or absence of the four articles. , a guide positioning means for the parts assembly apparatus or the parts manufacturing apparatus, and a count display means for displaying the quantity of articles, and the tape conveying apparatus and the parts assembly are controlled based on the counting result of the count display means. The storing and assembling operation of articles is performed in synchronization with the apparatus or the parts manufacturing apparatus.

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

FIG. 1 is a basic principle diagram showing how parts P are stored and taken out from a tape. In Fig. 1, to explain the basic principle by which a part P can be transported and taken out using a tape, the transport tape 3 has an inner part that is slightly larger than the external dimensions (depth, width, height) of the part P, as shown in the figure. Concave portions 3a having the same size are continuously provided at equal intervals.

In addition, pitch holes 3b are continuously drilled near both edges of the transport tape 3 as shown in the figure, and the pitch holes 3b engage with a sprocket 12, which will be described later, to apply driving force to the transport tape 3. I'm trying to convey it. 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 makes it possible to take it out. It is provided.

That is, in a state where the transport tape 3 and the cover tape 5 are moved in the direction of the arrow shown by the broken line in the figure, the part P is moved in the direction of the arrow shown by the broken line, and the cellars 1 to 5 are moved inside the recess 3a of the transport tape 3. After the cover tape 5 is applied, the part P is
While the conveyor tape 3 is moved in the direction of the arrow shown by the solid line in the figure, the stud 3 is moved so as to cover the upper surface.
When the cover tape 5 whose direction has been changed by the guide roller 17 which is freely rotatable is also moved in the direction of the arrow shown by the solid line, the part P can be taken out in the direction of the arrow shown by the solid line since its upper surface is exposed. becomes. In this way, after storing the parts P, the tape is wound up inside the reel for continuous storage and continuous supply.

Next, FIG. 2 is a side view showing a schematic configuration of the tape-type article conveyance device 50 of the embodiment, and shows how the above-mentioned conveyance tape 3 and cover tape 5 are wound inside each reel. .

In FIG. 2, a reinforcing member (not shown) is integrally provided on the board 1, which is processed from a plate material into the illustrated outline, and all of the components described below are basically supported on one side. It has as much strength as possible. On this board 1, a stud S indicated by a symbol S in the figure is installed vertically from above a framework (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.

Next, the transport tape 3 and the cover tape 5 with the component P set in the four parts 3a as described above are placed so that the cover tape 5 covers the opening of the recess 3a as shown in the figure, and the component mounting reel 6 is reeled. For this purpose, there is a component mounting reel 6, a cover tape take-up reel 8 for winding and supplying the cover tape 5, and a tape winding reel 8 for winding and supplying the transport tape 3. Each of the reels 7 is rotatable around the stud S, while the center of rotation 6 of these reels
c, 7c, 8c, the respective tape ends are fixed parts 6d, 7d,
8d, and each tape is wound up by the outer peripheral surface of the rotation center portion 6c, 7c8c of each reel. Each of these reels is provided with a rotating means, and the rotating means transmits rotational driving force while in contact with the outer peripheral edge of the reel.

Therefore, the component mounting reel 6, the tape winding reel 7, and the cover tape winding reel 8 are each provided with a rotating means for applying a driving force.

FIG. 3 is an external view showing the drive assembly 13 of the component mounting reel 6 among the rotating means. In FIG. 3, a tape take-up reel 7 and a cover tape take-up reel 8 are shown.
Drive assemblies 14 and 15 having a similar configuration are respectively provided in the drive assemblies 14 and 15, and the drive assembly 13 will be explained as a representative, and the explanation of the drive assemblies 14 and 15 will be omitted.

In FIG. 3, while driving the various tapes mentioned above,
A pair of rubber rollers 13b made of urethane rubber are attached to both ends of the output shaft of a motor 13a for generating tension on the tape. In order to bring the outer peripheral surfaces of these rubber rollers 13b into contact with the outer peripheral edges of the hubs 6a and 6b 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. 2, the motors 13a, 14a, 15a configured as explained based on FIG. The drive described below is performed by motors 13a and 14.
a, 15a performs this.

This control device 10 has a built-in counter, and a changeover switch loa and a counter 10b are provided at positions that can be operated from the outside. 10b is provided for counting and displaying the number of accommodated parts P.

As shown in the figure, this control section 10 is incorporated in a tape type article conveying device 50, and when set to an assembly device M and a parts manufacturing device N, which will be described later, a signal and a power line are connected to the assembly device M and a parts manufacturing device N. It is configured to automatically connect with device 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 can also be performed automatically. It is.

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 section 10. However, the rotational driving force of the stepping motor 9 is made rotatable around the stud S via a belt 11 shown in broken lines (so that the rotational driving force is transmitted to the sprocket gear 12b of the sprocket 12). There is.

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.

Between these two sprockets 12 are two component presence sensors 2 placed adjacent to each other in the recess 3a of the conveying tape 3.
0 is fixed to the substrate 1 at the same pitch as the recess 3a, and the presence or absence of parts P in the recess 3a is detected and counted.

Next, a guide roller 16 rotatably supported around a stud S on the substrate 1 is provided to change the direction of transport of the transport tape 3 from the vertical direction toward the sprocket 12 as shown in the figure. ing.

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, a guide rail 18 provided on the substrate 1 and formed by processing the plate material to form an arc is connected to a cover tape 5 that covers the top of the transport tape 3.
It is provided for guiding along the outer periphery of the arc.

Further, a pair of cam followers 19 rotatably supported around studs S near the left and right ends of the base 1 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 setting.

Next, FIGS. 4(a) and 4(b) are external perspective views showing how the tape-type article conveying device 50 is set in the assembly device M or the parts manufacturing device N equipped with the robot hunt H.
After being inserted into the mounting section 22 that is provided integrally with the assembly device M or the component manufacturing device N, a pair of cam followers 19 are inserted into the latching grooves 22a of the mounting section 22 as guides for relative positioning. It shows how it is pushed down and set into a predetermined position.

Each of these assembly devices M or component 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. When the part P manufactured by N is not stored in the recess 3a of the transport tape 3, the tape type article transport device 50 is set in the parts manufacturing apparatus N, while the part P manufactured in the recess 3a of the transport tape 3 is When the parts P are stored, the parts P are supplied to the assembly device M.

Next, the operation of the tape-type article conveying device 50 will be explained based on the operation diagram of the tape-type article conveying device 50 shown in FIG.

In this figure, the part P is empty in the recess 3a of the transport tape 3 of the tape-type article transport device 50, and the operation of storing the part P manufactured by the parts manufacturing apparatus N in the recess 3a of the transport tape 3 is shown. The operation modes in which the concave portion 3a of the conveying tape 3 is filled with parts P and the parts P are supplied to the assembly device M will be explained separately using the arrows shown in broken lines.

(Operation mode in which the component P manufactured by the component manufacturing device N is accommodated in the transport tape 3) The component manufacturing device N guides the cam follower 19, and then the component P is placed in the recess 3a of the transport tape 3. When storing the tape, the transport tape 3 is fully wound by the tape take-up reel 7, and the cover tape 5 is also fully wound by the cover tape take-up reel 8. It is being

Therefore, the component mounting reel 6 is in an empty state, and the transport tape 3 is attached to the rotation center 6C of the component mounting reel 60.
The overlapping ends of the cover tape 5 and the cover tape 5 are fixed in a barbed state.

Next, the switch ]a of the control unit 10 is automatically set to the accommodation side. Or set manually.

Then, the drive assembly 13, 14, 15 and the stepping motor 9 are rotated to accommodate the component P in the recess 3a of the conveying tape 3, but the component mounting reel 6 and the cover tape winding reel are rotated. 8, the tape winding reel 7, and the sprocket wheel 12 are rotated in the direction of the arrow shown by the broken line, respectively, and the tape is moved in the direction of the broken line arrow in FIG. P is accommodated, and the component mounting reel 6 is brought into a full winding state, while the tape winding reel 7
And the cover tape take-up reel 8 is made empty.

At this time, while the chipping motor 9 is rotated intermittently, the driving phase solid bodies 13, 14.1.5 are also rotated with a predetermined driving force, and in particular, the driving force of the stepping motor 9 is used to rotate the driving phase solid body 13, 14.1.5. The conveying tape 3 is moved and conveyed by a sprocket wheel 12. This moving conveyance force applies a rotational force to the tape take-up reel 7 in the direction of the dashed line arrow, but in this operating state, the driving force of the rotation assembly 14 is applied to the tape take-up reel 7 as shown by the solid line arrow. This rotational driving force is set to be sufficiently smaller than the tension applied to the conveying tape 3, so that the conveying tape 3 can be prevented from curling.

On the other hand, the rotation driving force by the rotation assembly 13 rotates the component mounting reel 6 in the direction of the broken line arrow, and this rotation in the direction of the broken line arrow winds the conveying tape 3 and the cover tape 5 onto the component mounting reel 6. At the same time, the tension applied to the cover tape 5 causes the cover tape take-up reel 8 to rotate in the direction of the dashed arrow, but the rotational driving force of the component mounting reel 6 is set to be smaller than the tension of the transport tape 3. This prevents walnuts from forming on the transport tape 3.

Next, the rotational force of the rotating assembly 15 that applies rotational driving force to the cover tape take-up reel 8 is set to be smaller than the tension applied to the cover tape 5, so that the cover tape 5 is not walnuted. This is to prevent this.

Further, the stepping motor 9 is set in advance so that the recess 3a of the conveying tape 3 is accurately and intermittently driven in the take-out section 2 when storing and taking out the parts P.

Therefore, the movement of the robot hand H of the parts manufacturing machine N is completely synchronized with the stepping motor 9, and the parts P manufactured by the parts manufacturing machine are transferred to the sprocket 1 in the take-out section 2.
2, the conveyor tape 3 can be accurately accommodated in the recess 3a.

In this way, the component mounting reel 6 is brought into a full winding state.

(Operation mode for supplying the part P from the transport tape 3 to the assembly device M).

When the component mounting reel 6 is fully wound, the tape type article conveying device 50 is removed from the component manufacturing machine and the robot hand H shown in FIG. 4(a) is moved. The cam follower 19 of the tape type article conveyance device 50 is guided and set to the provided assembly device M.

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

After this, the drive assembly 13, 14, 15 and the steering motor 9 are rotated, so that the component mounting reel 6
The cover tape take-up reel 8, the tape take-up reel 7, and the sprocket wheel 12 are each rotated in the direction of the arrow shown by the solid line, and the respective tapes are moved in the direction of the solid line arrow in FIG. , the parts P accommodated in the four parts 3a of the transport tape 3 can be taken out by a robot hand H in the take-out section 2.

Next, the transport tape 3 is transported in the direction of the arrow shown by the solid line by the driving force of the stepping motor 9, thereby applying a rotational force to the component mounting reel 6 in the direction of the arrow shown by the solid line.

On the other hand, the cover tape take-up reel 8 is rotated in the direction of the arrow shown by the solid line by the driving force of the rotation assembly 15, and the cover tape 5 is conveyed in the direction of the arrow shown by the solid line. Further, the driving force of the rotating assembly 13 applies a rotating force to the component mounting reel 6 in the direction of the arrow shown by the broken line, but this rotating force is set to be smaller than the tension of the conveying tape 3 and the cover tape 5. This prevents the conveyor tape 3 and cover tape 5 from becoming walnuts.

On the other hand, the driving force of the rotating assembly 14 is such that the tape winding reel 7 is rotated in the direction of the arrow shown by the solid line to wind up the transport tape 3, and the rotational force is set to be smaller than the tension of the transport tape 3. This is to prevent walnuts from forming on the conveying tape 3.

When all the parts P stored in the transport tape 3 are taken out in the take-out section 2 in this way, the tape-type article transport device 50 is removed from the assembly device M, and is attached to the parts manufacturing machine again to accommodate the parts P. .

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, so as shown in FIG. Multiple pieces (two in the figure) can be set.

Next, in the explanation of the operation of the tape type article conveying device 50, the control performed by the control device 1o will be explained based on a flowchart.

FIG. 6 is a schematic configuration block diagram of the tape-type article conveyance device 50, and the configuration of the tape-type article conveyance device 50 in this figure consists of components connected to the control device lo having the configuration explained based on FIG. , which shows the elements, and the components and elements already explained in Fig. 2 are numbered the same as in Fig. 2.
I will omit the explanation by adding a symbol.

Now, in FIG. 6, the motors constituting the drive assembly 13, 14, 15 and the stepping motor 9, respectively, and the stepping motor are connected to a motor driver that is connected to the control device 10 and generates a driving voltage and current. . An alarm device A is further connected to this control device 10,
Workers are notified of abnormalities. Further, an optical connector C2 and a power connector c1, which are optically coupled to the central control device of the parts manufacturing device N or the assembly device M to exchange signals and supply power, are each connected to the control device.

The operation of the tape type article conveying device 5o having the above configuration will be explained based on the flowcharts shown in FIGS. 7 and 8.

First, the flowchart of FIG. 7 shows an operation mode in which the parts P manufactured by the parts manufacturing apparatus N are accommodated on the conveying tape 3, and when the cam follower 19 is guided and set in the parts manufacturing apparatus N, step SIO is performed. The power is automatically turned on and the process proceeds to step Sll, where the component presence sensor 20 determines the presence/absence J of the component P, and when it is determined that the component is in the off state, that is, the component is "absent", the central control unit is instructed to enable component supply. On the other hand, in step Sll, when the component presence sensor 20 determines that the component P is present and turns it on, the process advances to step S13, where the remaining number (N) is incremented.Next, in step S14, the remaining number (N) It is determined whether the remaining number is greater than or equal to the set remaining number, and if the number is greater than or equal to the set remaining number, the alarm device A is operated in step S15 to notify that the number is almost full.

On the other hand, if the remaining number (N) is less than the set remaining number in step S14, the process proceeds to step S16, where it is determined whether the remaining number (N) is equal to the full number, and if they are equal,
After the process proceeds to step S18 and the apparatus is stopped, an abnormal state alarm is issued in step S19.

On the other hand, in step S16, if the remaining number (N) is not equal to the full number, the process advances to step S17, and the step motor SM9 reverses (in the direction of the broken line arrow in FIG. 5) based on the synchronized operation with the robot hand H. On the other hand, drive assembly 1
Motors 13a and 14a forming each of 3.14.15
, 15a are respectively supplied with driving voltages of 15 volts, 5 V, and 5 volts to drive each of the reels described above to generate appropriate tension on each tape and remove the walnuts. . This operation is repeated until N is full.

Next, the operation mode for supplying the parts P from the transport tape 3 to the assembly apparatus M will be explained based on the flowchart of FIG.

When the component mounting reel 6 is in the full winding state, the tape type article conveying device 50 is transferred to the component manufacturing device N.
The cam follower 19 of the tape type article conveying device 50 is guided and set in the assembly device M equipped with the robot hand H shown in FIG. The switch 10a is manually or automatically set to the supply side, and the power is automatically turned on in the following step S30, and then the switch 10a is turned on in step S31.
, the presence or absence of the part P is determined by the part presence sensor 20.
When it is determined that the component P is on, that is, that the component P is present, an instruction is given to the central control device of the assembly device M to enable the component to be taken out.

On the other hand, in step S31, when the component presence sensor 20 determines whether the component P is "absent" and is turned off, the process proceeds to step S33, where the remaining number (N) is subtracted.

Next, in step S34, it is determined whether the remaining number (N) is greater than the set remaining number, and if it is smaller, step S34 is performed.
At step 35, the alarm device A is operated to notify that there are few remaining numbers.

On the other hand, if it is determined in step S34 that the remaining number (N) is greater than or equal to the set remaining number, the process proceeds to step S36, where it is determined whether or not the remaining number (N) is (rOJl).
In the case of JJ, the process proceeds to step S39, where the device is stopped, and the alarm device A is activated in the next step S40, and the process ends. Further, if it is determined in step S36 that the remaining number (N) is not "0", the process advances to step S37,
The number of continuous OFF state detections n of the component presence sensor 20 is (Q
), and if it is, the process proceeds to step S39, where the apparatus is stopped and the next step S40 is performed.
At this point, the alarm device A is activated and the process ends.

On the other hand, if the number of continuous OFF state detections n is less than (Q), the process advances to step S38, and the step motor 9 rotates normally (in the direction of the solid arrow in FIG. 5), while the drive assembly 13
．． 14, motors 13a, 14a, which constitute each of ]5;
Supply driving voltage power of 5V, 15V, and 5V to 1.5a, respectively, and drive each reel as described above to generate appropriate tension on each tape and remove walnuts. do. Repeat this operation until N becomes "O"
Continue until.

Thereafter, by repeating the operation described in item 1, the parts P manufactured by the parts manufacturing apparatus N are supplied to the assembly apparatus M.

In the above embodiment, the control section 10 is incorporated in the tape-type article conveyance device 5o, and when set in the assembly device M and the parts manufacturing device, the signal lines are automatically connected, but it functions independently. Anything 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.

In addition, since the transport tape and cover tape are wound up without any adhesives, they can be used repeatedly semi-permanently, eliminating the need to replace the tapes.
We were able to significantly reduce running costs.

Furthermore, since the stepping motor 9 for driving and the rotating assemblies 13, 14, and 15 are used, troubles such as tape winding errors and parts P falling due to tape bending, 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 it can also be used for parts with complex shapes by forming a recess 3a in the conveying tape 3 so that the part P can be accurately positioned. Needless to say.

[Effects of the invention] As explained above, the article can be accurately positioned on the tape, the article can be handled by a robot device, etc., there is no need to replace the tape, and there is no sway on the tape when winding it. It is possible to provide a tape-type article conveyance device that can reliably convey articles because no error occurs, and also enables detection of the number of parts and allows fully automatic robot hand operation.
