Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention automatically winds a special coil used in, for example, a switching transformer with high efficiency while automatically performing auxiliary work required for the winding. The present invention relates to a rotating shaft type winding device.

(Prior Art) FIG. 11 shows a conventional transfer-type automatic winding machine, and is an explanatory view showing a winding station among a plurality of work stations.

A is a transport mechanism, D is a delivery mechanism, and C is a winding station.

The coil bobbin 1a, which is the target member for the winding work, is mounted on the jig 2a and mounted on the pallet A ₁ . The pallet A ₁ is conveyed by the rail A _{2 in the} direction perpendicular to the paper surface and stops at a position facing the winding station C.

Delivery mechanism D is the coil bobbin 1a from the pallet A ₁
For receiving the coil bobbins already wound and returning them onto the pallet A ₁ .

The column D ₁ of the delivery mechanism D is reciprocally driven in the left-right direction in the figure along the linear guide D ₂ .

The column D ₁ rotatably supports the hands D ₄ and D ₅ by the shaft D ₃ .

When column D ₁ moves to the right from the position shown, hand D ₄
Becomes the D ₆ position indicated by the imaginary line, and grips the jig 2a.
When the column D ₁ returns to the position shown in the figure, the hand returns to the position D ₄ , and the coil bobbin 1b position and the jig 2b position are respectively moved. Hand D ₄ is 180 around axis D ₃ .
When turned to the D ₅ position by 1 degree, the coil bobbin 1 at the 1b position
The jig at the c position and the jig at the 2b position are conveyed to the 2c position.

When the column D ₁ is driven further to the left in the figure, it moves to the hand D ₇ position at the D ₅ position and moves the coil bobbin to the 1d position,
The jig is moved forward to the 2d position, and the jig 2d is mounted on the jig holder C ₃ of the winding station C.

The jig holder C ₃ is mounted on the spindle C ₂ of the winding machine and is rotated. The coil bobbin 1d is wound with the conductive wire supplied from the wire guide C ₄ while being rotated together with the jig 2d.

The wound coil bobbin 1d is returned to the pallet A ₁ of the transport mechanism A in the reverse order, guided by the rail A ₂ and sent to the next station.

In the conventional coil winding, even if the delivery station D is provided as in the winding station C shown in FIG. 11, no particular trouble occurs.

However, switching transformers have been developed in recent years and are rapidly becoming popular. In this switching transformer, additional work such as forming and taping of the wire material must be performed during the winding work, and the winding material must be replaced during the winding work.

Therefore, when trying to automatically wind the switching transformer, a large number of automatic devices (for example, a start wire right angle inserting device, a finish wire right angle ejecting device, an insulating cross taping device, and the like are installed around the bobbin mounted on the winding machine. Nozzle changing device, wrapping device, etc.) must be installed.

The switching transformer is described as an example, but in addition to this, coils that require a lot of additional work during the winding work are being developed and studied. Hereinafter, these special coils are collectively referred to as a switching transformer or the like.

For the above reason, in the conventional automatic winding machine shown in FIG. 11, the delivery mechanism D interferes with automatic winding of the switching transformer and the like. That is, since a part of the surrounding space near the tip of the spindle C ₂ to which the coil bobbin 1d is to be mounted is closed by the delivery mechanism D, full automation including auxiliary work cannot be performed.

Japanese Patent Publication No. Sho 63-53684 is known as a winding machine that does not require a delivery device in the space around the bobbin to be wound. FIG. 12 is a sectional view disclosed in the above publication.

Reference numeral 22 denotes a rotary conveyance path, which is provided with four guide members 24, 25, 26, 27. The holding device 38 is supported by the guide member and holds the bobbin B.

The winding device 47 is arranged so as to face the bobbin B. According to the winding machine according to this known technique, the holding device 38
Since it is not necessary to provide a work transfer device in the space S ₁ opposed to the bobbin B held by, the winding device and the automatic device for work attached to the winding must be provided in this space S ₁ . You can

However, when the carrousel 22 is rotated as the arc arrow R, the bobbin B rotates the arc S ₂ as the locus. For this reason, the winding device or an automatic device attached thereto cannot be arranged in the space surrounded by the arc S ₂ . That is, the space surrounded by the arc S ₂ becomes a dead space in the automatic device arrangement.

A winding having a structure in which the above-mentioned drawbacks are eliminated and there is no obstacle in the space facing the bobbin attached to the spindle, the space above and below the bobbin, and the winding device and its accessory devices can be arranged. As a wire machine, a winding machine disclosed by Japanese Utility Model Publication No. 1-22014 is known, and FIG. 13 is a perspective view disclosed in this publication. The index table 11 is installed on the winding machine body 33.
Is intermittently rotated by 90 degrees in the direction of the arrow r.

Around the index table 11, a loading unit 72 as a work station and a winding unit 12
A connection unit 71 and an unloading unit 73 are provided.

The index table 11 has a hollow square support 31.
Spindles 14 are lined up on each side of. A bobbin (not shown) is attached to the spindle 14 to support and rotate the bobbin. 45 is a jig for attaching the bobbin to the spindle. In this known winding machine, a center support 46 is provided so as to concentrically face the spindle 14.

The loading unit 72 is provided with a loading mechanism 83 for attaching the bobbin to the spindle 14.

Further, the winding unit 12 is provided with a carriage 55 on which a wire guide 16 for guiding the winding material is mounted and which is driven in three orthogonal X, Y and Z directions.

The connection unit 71 is an automatic device that connects the end of the wound wire to the printed wiring of a bobbin (not shown).

The unloading unit 73 is equipped with a take-out mechanism 85 for removing the wound bobbin from the spindle 14.

FIG. 14 is an explanatory diagram schematically showing a state in which a winding machine for a switching transformer is configured by applying the winding machine according to the known technique shown in FIG.

A winding machine body 33 having the same drawing reference numbers as in FIG. 13,
The index table 11 and the spindle 14 are the same or similar constituent members as in the above-mentioned known example. The bobbin B is attached to the tip of the spindle 14 as shown by the phantom line.

Since there is a margin in the space around the bobbin B, the nozzle exchanging device 1, the finish wire right angle feeding device 2, the insulating cross taping device 3, the tape holder 4, the cutter 5, the wrapping device 6, the start wire retainer 10, etc. Automatic equipment specific to the line can be provided. Numerals 7 and 8 are cylinders for reciprocatingly driving the brackets of the automatic equipment in the left-right direction in the drawing so as to approach and separate from the bobbin B.

(Problems to be Solved by the Invention) In the known winding machine shown in FIG. 13, as described with reference to FIG. 14, the front space of the bobbin mounted on the tip of the spindle (left space in FIG. 14). The upper space and the lower space have no obstacles and are suitable for arranging automatic equipment such as a switching transformer for performing auxiliary work unique to winding work.

However, as is apparent from the basic configuration shown in FIG. 13, only four sets of work stations can be installed.

In the example of FIG. 13, the loading unit 72 and the unloading unit 73 occupy two sets of the above four sets of work stations, so that only two sets of effective work stations of the winding unit 12 and the connection unit 71 are available. Cannot be provided.

In order to increase the number of effective work stations installed, the shape of the support base 31 may be polygonal with a pentagon or more, but the layout of the entire factory including the winding machine, especially the configuration of the transportation route, should be considered. If it is complicated, it is not practical.

On the other hand, in Japanese Utility Model Laid-Open No. 1-307016, various automatic devices for increasing wire are arranged along a conveyor, and winding processing is performed while moving a pallet (spindle module) holding a bobbin on the conveyor. There is disclosed an automatic winding processing device for performing the operation. According to this, the above-mentioned conventional problems can be solved to some extent, but since this device is configured to apply the rotational driving force to the pallet from an external driving device through a single path. When attempting to rotationally drive multiple spindles, a mechanism for interlocking each spindle is required inside the pallet, which complicates the structure and increases the weight, which causes troubles in transportation and handling on the conveyor. There was a problem. In addition, since there is only one power transmission path for the pallets, it is not possible to handle a plurality of pallets.

The invention of the present application has been made by paying attention to such a conventional problem, and for arranging automatic devices without obstacles in the upper space, the front space, and the lower space of the bobbin attached to the spindle. It is a first object of the present invention to provide a winding device which has a large space, is not limited in the number of work stations to be installed, and is easy to handle and change the specifications of a pallet, and which is suitable for winding of a switching transformer or the like.

A second object of the present application is to provide a multiple winding device capable of efficiently producing coils having various specifications by connecting a plurality of such winding devices.

(Means and Action 1 for Solving the Problem) In order to achieve the first object, the following winding device is configured as a first invention.

That is, in the present invention, one or more spindles for mounting bobbins are mounted on the transfer pallet, and a conveyor for transferring the pallet is installed on the base member of the automatic winding processing device. Then, this conveyor has a structure in which the pallet is basically translated in the horizontal direction at a right angle to the spindle.

A spindle which is provided with means for positioning and temporarily fixing the above-mentioned pallet at a predetermined position, that is, a position facing the automatic winding processing device, and mounted on the pallet positioned as described above. The drive means for rotating the coil is installed on the base member of the automatic device for winding processing, and
A clutch device for transmitting the rotation output of the drive means to the spindle is provided. A plurality of clutch devices are provided so as to correspond to a plurality of spindles facing each other on the pallet, and drive is performed for each individual spindle.

According to the wire increasing device configured as described above, since the spindle for mounting the bobbin and holding the bobbin is mounted on the pallet, it is not necessary to install the delivery mechanism by conveying the pallet by the conveyor. . That is, unlike the conventional example shown in FIG. 11, the front space of the spindle C ₂ is not occupied by the transfer mechanism D.

Further, since the pallet is not rotated but translated in parallel, the spindle mounted therein also translates horizontally without rotation. Therefore, unlike the known example shown in FIG. 12, there is no restriction that another device cannot be installed in the rotation locus arc S _{2 of the} spindle.

On the other hand, the pallet is fixed every time the pallet is moved to a predetermined position of the automatic device, and the rotational force from the driving means is transmitted through the clutch device. In this case, the pallet itself does not require a drive unit or interlocking mechanism between each spindle,
The pallet will be smaller and lighter, and it will be easier to convey it on a conveyor. Further, since the clutch device is configured to transmit the rotational force of the drive device for each individual spindle, winding is possible regardless of the pallet specifications (number of spindles). Pallet 1 with 4 spindles when installed at equal pitch on 4 axes
It can be used with two bases or two pallets with two spindles. Further, since the pallet is positioned for each individual automatic device, even if a large number of automatic devices are connected, the positioning accuracy does not deteriorate due to deformation of the installation floor surface, etc. Therefore, not only the pallet but also the conveyor itself. Can also have a simple configuration.

Further, since the pallet is horizontally translated by the conveyor, it is possible to install a large number of work stations or automatic devices having different functions along the transfer path, as in the known example of FIG. The number of work stations is not limited to four.

(Means and Action 2 for Solving the Problems) Further, in order to achieve the above-mentioned second object, the following multiple-type winding device is configured as a second invention.

That is, the conveyor of the winding device having the automatic device as described above is composed of a feed side conveyor and a return side conveyor having a predetermined length in parallel with each other, and each of them is a feed side corresponding to another adjacent automatic device. Connect to the conveyor and the return conveyor.

A transfer device that transfers the pallet reaching the end of one conveyor to the other conveyor is provided between the conveyor and the return conveyor of the automatic equipment located at the end.

According to the multiple winding device configured as described above, the following action is performed in addition to the same action as that of the winding device configured for the first purpose.

That is, in the above-mentioned configuration, since various kinds of automatic equipment required for winding processing are connected to each other through the common conveyors on the feed side and the return side, various kinds of automatic equipment are used for winding purpose or coil. It is possible to freely connect or rearrange them according to the specifications of the.

In addition, the coil bobbin supported by the spindle on the pallet moves along the conveyor on the feed side, and the necessary processing is sequentially performed by various automatic devices connected to each other, but the series of processing is completed. When the pallet reaches the end of the feed side conveyor, it is transferred to the return side conveyor by the transfer device, and is conveyed in the opposite direction. Further, the pallet that has reached the end of the return side conveyor is transferred to the feed side conveyor again. That is, the pallet rides on the conveyor on the sending side and the conveyor on the returning side and circulates among various automatic devices. Therefore, even when it is necessary to repeat the same process, this can be realized with the minimum necessary device configuration, or the installation space of the winding device can be saved. Of course, it is also possible to connect a plurality of automatic devices including the same type of automatic device and complete the winding by only reciprocating the pallet once.

(Embodiment 1) FIG. 1 is a side view showing an embodiment of a winding device according to the first invention of the present application, and FIG. 2 is a plan view of the same. This embodiment is an example in which a switching transformer is wound.

As shown in FIG. 1, a pedestal 21 is fixed on a winding machine main body 20, and a conveyor 22 is installed on it.

The above conveyor 22 is a pallet equipped with a spindle 14.
Transport 23.

FIG. 2 shows two pallets 23 each having two spindles 14 rotatably mounted therein. The above-mentioned conveyor 22 uses the pallet 23 in the vertical direction of the paper surface of FIG.
Move parallel to the plane of the drawing (horizontal direction) and do not rotate.

Positioning and fixing means (24) is installed on the pedestal (21) which is a base part so that the pallet (23) stops at a predetermined position and is temporarily fixed. The positioning and fixing means 24 is known per se, and detects the position of the pallet 23 by a sensor (not shown) and fixes it at a predetermined position.

A drive device 25 having a clutch device 26 facing the spindle 14 mounted on the pallet 23 stopped at a predetermined position is installed on the pedestal 21. 27 is a transmission shaft for supplying rotational power to the drive unit 25, and 28 is a transmission belt.

The drive unit 25 and the clutch unit 26 are shown in FIGS. 3 and 4.
Shows the details of. As shown in FIG. 3, the driving device 25 is of a four-axis type for simultaneously driving each spindle 14 with respect to two adjacent pallets 23, and each driving shaft 30 is driven in the same direction via a belt transmission mechanism (not shown). Rotate at the same speed. The transmission block 31 supporting each drive shaft 30 can be axially driven with respect to the gantry 21 via an actuator (not shown), and the clutch 26 is engaged at the forward position shown by the phantom line in FIG. Is transmitted to the spindle 14 on the pallet 23, and at the retracted position shown by the solid line, the clutch 26 separates to interrupt the transmission of power.

The clutch 26 is a tapered portion formed at one end of the spindle 14.
The holder 34 includes a holder 32 having a tapered hole 33 that fits in the holder 32, and the holder 34 is fixed to one end of the drive shaft 30. A pin 35 penetrates the base end of the tapered portion 32 in the radial direction, while the tapered portion 32 is attached to the holder 34 at the front end of the holder 34.
The pin when it is being fitted into the tapered hole 33.
There is a groove 36 that engages with 35. A helical groove 37 is formed in the body of each holder 34. With this helical groove 37, the holder 34 has a portion fixed to the drive shaft 30 that is connected to the spindle 14 slightly in the axial and radial directions. Displacement is allowed.

Therefore, when the transmission block 31 is moved forward from the state shown in the drawing, each drive shaft 30 and the holder 34 rotate and approach the taper portion 32 of the spindle 14 facing each other, and the spindle 14 of the spindle 14 with respect to the taper hole 33 of the holder 34. The rotation of the drive shaft 30 is transmitted to the spindle 14 when the taper portion 32 enters to some extent and each groove 36 and the pin 35 engage with each other. From this position, move further forward and tap the taper portion 32 of the spindle 14 and the holder.
When the taper hole 33 of 34 comes into close contact, the transmission block 31
Is stopped from moving forward, and the clutch device 26 is completely engaged. At this time, even if there is a positional deviation between the spindle 14 and the drive shaft 30 in the radial direction and the axial direction due to a dimensional error or the like, this is absorbed by the deformation of the helical groove 37 of the holder 34 described above. It is possible to smoothly connect the clutch device 26 and transmit the rotational force,
Further, it is possible to prevent the occurrence of vibration during the driving of the spindle 14.

In this way, the spindle 14 mounted on the pallet 23 that is stopped at a predetermined position and temporarily fixed is rotationally driven by the drive device 25 while holding the bobbin B.

When carrying out the present invention, one pallet as in the present embodiment
A structure in which two spindles 14 are mounted on 23, and each spindle is simultaneously driven with respect to two pallets 23, that is, a transmission system is configured to rotate four spindles 14 by one transmission shaft 27. This is advantageous because the winding of four bobbins B can be performed simultaneously.

Since the conveyor 22 of this embodiment moves the pallet 23 in parallel and does not rotate it, the spindle 14 is also moved in parallel. Therefore, in the upper space, front space (left space in the figure) and lower space of the spindle 14,
Even if the automatic devices for performing the auxiliary work accompanying the winding work are arranged, these automatic devices do not interfere with the spindle 14.

FIG. 1 shows only a part of ancillary automatic equipment peculiar to the switching transformer winding by imaginary lines so as not to make the drawing excessively complicated. That is, what is shown in the drawing is a nozzle changing device 1, a finish wire right angle device 2, an insulating cross taping device 3, a table holder 4, a cutter 5, a lapping device 6, a start wire retainer 10, and an accessory for a switching transformer winding. Equipments 7 and 8 are cylinders for advancing and retracting auxiliary equipment.

As is apparent from FIG. 1, an upper space, a front space (a space on the right side in the drawing) and a lower space of the bobbin B attached to the tip of the spindle 14 are provided with auxiliary equipment for switching transformer windings. It can be used as a space for.

Moreover, the pallet 23 is equipped with the spindle 14 and is vertical to the paper surface of FIG. 1 and the vertical direction (horizontal direction) of the paper surface of FIG.
Be transported to. Therefore, the work stations can be installed along this conveyance path, and the number of installations is not particularly limited. That is, unlike the known example shown in FIG. 13, the number of work stations is not limited to four sets.

(Embodiment 2) Next, an embodiment of the winding device according to the second invention of the present application will be described with reference to the drawings starting from FIG. In the following drawings, the parts corresponding to those in FIGS. 1 to 4 are designated by the same reference numerals.

The winding device shown in FIG. 5 is basically a four-axis winding device similar to that shown in FIG. 1, but with a drive device 25 for driving the spindle 14 sandwiched between two rows of conveyors. It differs from that of FIG. 1 in that it includes 22A and 22B. Each conveyor 22A
And 22B are composed of a free roller conveyor or a belt conveyor having a predetermined length, and are arranged in parallel on the same horizontal plane.

The conveyor 22A located on the left side of the drive device 25 in the figure is the feed side, and the conveyor 22B also located on the right side is the return side. The bobbin B supported by the pallet 23 and the spindle 14 is shown.
In the same manner as in FIG. 1, winding processing is performed while moving on the feed side conveyor 22A. The pallet 23 on which the necessary winding processing has been performed is transferred to the return side conveyor 22B by a transfer device described later, conveyed in the direction opposite to the sending side, and moved to the next step.

FIG. 5 shows a winding machine, but in the present invention, various automatic equipment for winding processing, such as a feed conveyor 22A and a return conveyor 22B, for example, a work (bobbin). Supply device, taping device, soldering device,
Welding equipment, inspection equipment, work discharge equipment, etc. are connected as needed according to coil specifications, and pallets
The coil winding process is completed by moving the coil.

6A to 6E show an example of the configuration, and in the figure, reference symbol W indicates a winding machine and reference symbol SB indicates another automatic winding processing device.

For example, the coil winding process is performed by the automatic devices W and SB while the pallet 23 flows from the left side to the right side of the feed side conveyor 22A, and after each step is completed, the coil is wound on the right end of the feed side conveyor 22A. The reached pallet 23 is the return conveyor 2
The pallet 23 that has been transferred to 2B and reached the left end of the return side conveyor 22B is transferred to the transfer side conveyor 22A again so that the pallet 23 is circulated.

6A to 6C is a circulation type in which the winding is completed by repeatedly circulating the pallet 23 having the bobbin B and the spindle 14 between the respective automatic devices W and SB for a required cycle. This is suitable for cases where the installation space of the equipment is limited or when winding processing is desired with a small number of automatic equipment. FIGS. 6D and 6E are examples of one-way type in which a large number of automatic devices W and SB are connected so as to complete necessary winding processing while the pallet 23 moves from one end to the other end of the conveyor 22A. With this configuration, higher production efficiency can be obtained.

In FIGS. 7 and 8, as described above, the feed side conveyor 22
An example of a transfer device for transferring the pallet 23 between the A and the return side conveyor 22B is shown.

Column 4 fixed so that it is located between each conveyor 22A, 22B
An oscillating shaft 41 is supported in the vertical direction at 0, an actuator 42 for driving the oscillating shaft 41 is provided below the oscillating shaft 41, and a transfer arm 43 is horizontally fixed to the upper end of the oscillating shaft 41. A guide member 44 having a C-shaped cross section is provided on the lower surface side of the swing end of the transfer arm 43. On the other hand, the pallet 23 is provided with an engaging member (not shown) which is fitted into the guide member 44.

In the above structure, when the pallet 23 approaches the end of the feed side conveyor 22A, the engaging member thereof enters the guide member 44 of the transfer arm 43. When the pallet 23 further moves and the guide member 44 and the pallet 23 are completely engaged,
When this is detected by a sensor (not shown), the actuator 42 operates and pushes up the turning shaft 41 to raise the pallet 23 by a slight amount to a position where it does not interfere with the conveyor 22A, and then turns 180 degrees. As a result, since the pallet 23 moves together with the transfer arm 43 onto the return side conveyor 22B,
Next, the actuator 42 lowers the pivot shaft 41 to move the pallet.
Seat 23 on return conveyor 22B. The pallet 23 transferred in this manner is conveyed by the return side conveyor 22B in the direction opposite to the feeding side. When the pallet 23 moves and separates from the guide member 44 of the transfer arm 43, the transfer arm 43
Is rotated 180 degrees in the opposite direction by the actuator 42 to return to the initial position, and the next pallet 23 is transferred. By repeating this operation, the pallets 23 are transferred one after another between the feed side conveyor 22A and the return side conveyor 22B.

In the configuration in which the feed side conveyor 22A and the return side conveyor 22B are arranged in a horizontal plane as shown in the figure, a U-turn type conveyor is adopted as the transfer device instead of the robot type transfer device described above. You can also

Further, the arrangement of the conveyor 22A on the sending side and the conveyor 22B on the returning side is not limited to the parallel arrangement in the horizontal plane as described above. For example, as shown in FIG. 9 and FIG. The return side conveyor 22B is arranged in the pallet via the lift 50 as a transfer device arranged at both ends.
23 may be circulated. In this example, from the left side of the drawing, the work supply device 51, the first taping device 52,
The first winding device 53, the film coating device 54, the second winding device 55, the second taping device 56, and the work ejecting device 57 are arranged to reach the work ejecting device 57 to the work feeding device 51. This is a one-way type in which the winding process for the bobbin is completed by a one-way flow.

(Effect 1 of the invention) As described above, since the winding device according to the present invention is provided with the pallet having the spindle and the conveyor for horizontally conveying the pallet, an arbitrary number of the pallets are provided along the conveying path. Work stations can be installed, and the number of work stations installed is not limited.

Further, since the pallet equipped with the spindle is horizontally translated and conveyed without rotation, the bobbin attached to the tip of the spindle is not vertically rotated. Therefore, it is possible to arrange automatic devices in the upper and lower spaces of the bobbin, and it is suitable as a winding machine such as a switching transformer which requires installation of a large number of automatic devices for incidental work.

The spindle mounted on the pallet can be transported with the bobbin attached to its tip, and is rotated by the drive means in the positioned state, so that there is no need to provide a bobbin delivery machine at the work station.
Therefore, the front space of the bobbin attached to the tip of the spindle is not occupied by the delivery mechanism, and automatic equipment can be arranged in this front space, which is more suitable as a winding machine such as a switching transformer.

On the other hand, since the pallets are individually positioned by automatic equipment and the driving force from the driving device is transmitted to the spindle on the pallets via the clutch device, the pallets and the conveyor for conveying the pallets are The configuration can be simplified. Also, because a plurality of clutch devices are arranged to support a plurality of spindles, the number of spindles is not restricted, that is, the required number of spindles can be driven individually, or the specifications of the pallet can be freely selected. As a result, it is possible to obtain the effect of increasing the production efficiency.

(Effect 2 of the invention) Further, according to the multiple-correspondence winding device according to the second invention, there is provided an automatic winding processing apparatus having a feed-side conveyor and a return-side conveyor each having a predetermined length. Since a plurality of pallets are connected through the conveyor and the transfer device provided at the end of the conveyor circulates the pallet between the feed-side conveyor and the return-side conveyor, the winding device according to the first invention In addition to the same effect, the following effect is exhibited.

That is, since various kinds of automatic devices for winding processing can be freely connected and disconnected through the conveyer on the sending side and the conveyer on the returning side, the device can be easily increased or decreased and reconfigured according to the specifications of the coil, so that a large variety of products It can be used for small quantity production at low cost.

Further, since the pallet is circulated between the feed side conveyor and the return side conveyor, the work of repeating the same kind of processing can be realized with the equipment configuration of the minimum required source, and therefore the cost and the equipment installation space are greatly saved. It is possible.
