Description

The present invention relates to a rod supply device for supplying a rod used for rod hanging in a sausage rod hanging device for hanging a chained sausage on a rod in a loop shape.

The applicant has previously proposed a sausage rod hanging device that horizontally transfers a cantilevered rod and hangs a chain of sausages on the rod (see Patent Document 1).

When the above-mentioned sausage rod hanging device is adopted, the chained sausage for one rod can be hung on the rod simply by transferring the cantilevered rod in the horizontal direction, which simplifies the structure of the rod hanging device. The device can be realized at low cost.

In addition, the applicant has proposed a rod supply device for the above-mentioned sausage rod hanging device, in which the rod is taken out from the storage location and then handed over to the rod gripping means (see the same document).

This rod supply device rotates a rod extraction member having a groove formed on the outer peripheral portion of a disk, and stores the rod at the bottom of the rods stored in the storage place in the groove of the rod separation means and takes it out. After that, it is transferred to the gripping means.

If the above-mentioned rod supply device is used, a new rod can be supplied to the gripping device in conjunction with the ejection of the rod that has been hooked, so that the sausage rod hooking device can be continuously operated.

Japanese Unexamined Patent Publication No. 2019-97539

By the way, in the above-mentioned sausage rod hanging device, if the rod gripped by the gripping means is bent, the tip of the rod will come off the loop of the chained sausage when the rod is transferred in the horizontal direction, and the rod hanging will be released. There is a risk of failure.

For this reason, in the past, the operator visually checked the degree of bending of the rod, and excluded rods with a large amount of bending so that they would not be used for rod hanging. I couldn't make full use of the characteristics of the rod supply device for the purpose of conversion.

The present invention has been made in view of such a situation, and by incorporating a means for measuring the bending amount of the rod, the rod exceeding a certain bending amount is automatically eliminated, and the rod can be used without relying on human hands. It is an object of the present invention to provide a rod supply device capable of continuous supply.

In order to achieve the above object, the rod supply device according to the present invention is a rod supply device that takes out one rod from a place where a plurality of rods are stored and delivers the rod to a rod gripping means for gripping the rod in a cantilevered state. hand,

A rod transfer member that delivers the rod taken out from the rod extraction member to the rod gripping means, and a rod transfer member.
A rod bending amount measuring means for measuring the bending amount of the rod taken out by the rod taking-out member, and a rod bending amount measuring means.
The rod taking-out member, the rod transfer member, and the controller for controlling the operation of the rod bending amount measuring means are provided.
The controller is characterized in that when the bending amount of the rod measured by the rod bending amount measuring means exceeds a predetermined value, the delivery of the rod to the rod gripping means is prevented.

Here, the rod bending amount measuring means is composed of a bending amount measuring member in which a light source that emits parallel light and an optical sensor that receives the parallel light are integrated, and the bending amount measuring member is placed in a vertical plane. It is preferable to measure the bending amount of the rod by rotating it and detecting the amount of light blocked by the rod placed horizontally between the light source and the optical sensor.

It is preferable that the bending amount measuring member is installed in the vicinity of both ends of the rod supported horizontally.

The rod removal member is composed of a disk having a groove formed in the outer peripheral portion thereof to accommodate the rod, and by rotating around a shaft, one rod is taken out from the storage place of the rod and the groove is formed. It is preferable to house in.

The rod bending amount measuring means further has a recess for accommodating the rod, and by swiveling around a shaft, a pair of rod support arms that take out the rod from the groove of the rod extraction member and support it horizontally. It is preferable to provide.

It is preferable that the rod bending amount measuring means is further provided at the outlet of the rod taking-out member and provided with a shutter that prevents the rod from being delivered to the rod transfer member.

If the rod supply device according to the present invention is used, a rod having a large bending amount is automatically removed in the middle of supply, and no manpower is required to select the rod, which contributes to labor saving. Moreover, since it can be retrofitted to the existing rod supply device, it has a great practical merit.

<Configuration and operation of sausage rod hanging device>
Before explaining the rod supply device 1 according to the present embodiment, the outline of the sausage rod hanging device (see Patent Document 1) using the cantilevered rod previously proposed by the applicant with reference to FIG. The configuration and basic operation will be explained.

The sausage rod hanging device is a conveyor chain 6 (indicated by a two-dot chain line in FIG. 4), which is an endless circulation body, to which a plurality of hooks 5 for suspending the chain-shaped sausage S are attached at a constant pitch. .. In FIG. 4, only three hooks 5 are displayed, and the others are omitted.

Each hook 5 has a function of suspending the chained sausage S so as to form a loop and a function of transferring the suspended chained sausage S to a rod P inserted through the loop. I have.

Specifically, the hook portion 52 for hanging the chained sausage S is attached to the hook main body 51 in a rotatable state, and the hook portion 52 is suspended with the binding portion of the chained sausage S hooked on the front end of the hook portion 52. Can be lowered. Further, above the front portion of the hook main body 51, a guide portion 53 for guiding the sausage S suspended from the sausage manufacturing apparatus (not shown) to the hook portion 52 is attached.

In the sausage rod hanging device described in Patent Document 1, the above-mentioned hook is used, and the tip of the rod P gripped by the rod gripping device 3 in a cantilevered state is inserted into the loop of the chained sausage S, and the rod P is inserted. The sausage is transferred from the hook 5 to the rod P while transferring the sausage in the axial direction.

The rod hanging operation in the sausage rod hanging device is divided into the following six steps A to F, and the following steps are executed while the hook 5 goes around along the trajectory of the chain 6.
A: Suspension of chained sausage S to hook 5 B: Transfer of hook 5 from which chained sausage S is suspended C: Removal and transfer of rod P from storage location D: From hook 5 of chained sausage S Transfer to rod P E: Discharge of rod P on which chain sausage S is hung F: Transfer of empty hook 5

Briefly explaining each of the above steps, in step A, the chain 6 is used to transfer the hook 5 so as to swirl around the sprocket (not shown) and to the adjacent sausage manufacturing apparatus (toward the paper surface). The chained sausage S sent out from (installed on the right side, not shown) is hung on the hook portion 52 of the hook 5.

In step B, a group of hooks 5 in which a chain sausage S of a length that can be hung on one rod P is suspended is transferred to a region (central portion in FIG. 4) where the chain 6 is used to hang the hooks. do.

In step C, after taking out one rod P from the storage place of the rod by using the rod supply device 1 (see FIG. 1, arranged on the left side when facing the paper surface) installed at a position adjacent to the chain 6. , Handed over to the rod gripping means 3 (see FIG. 1) provided below the rod transferring means 4.

In step D, the cantilevered rod P whose one end is gripped by the rod gripping means 3 is transferred in the axial direction of the rod P (indicated by an arrow in FIG. 4) using the rod transfer means 4. It is inserted into the loop of the chain sausage S suspended from the hook 5, and the rod P is transferred in accordance with the transfer of the hook 5. At the same time, the chained sausage S for one rod is transferred from the hook 5 to the rod P by using the transfer executing means 7 (see FIG. 4).

In the step E, the rod P on which the chain sausage S for one rod is hung is returned to the initial position and discharged by using the rod discharging means (not shown).

In the step F, the empty hook 5 from which the chained sausage S has been removed is transferred to the region where the step A is performed by using the chain 6.

Next, with reference to FIG. 4, the operation when the chained sausage S suspended from the hook 5 is transferred to the rod P gripped by the rod gripping means 3 will be described.

The hook portion 52 of the hook 5 rotates clockwise due to its own weight and the weight of the chain sausage S hung on the hook portion 52 when no external force is applied, and is hung on the hook portion 52 as it is. The chained sausage S falls from the hook 5.

Therefore, a pair of roller guide members 71 and 72 are arranged in the transfer direction of the hook 5 (indicated by an arrow in FIG. 4), and a roller (roller) that rotates integrally with the hook portion 52 in the guide groove G1 formed between the pair of roller guide members 71 and 72. The position of the hook portion 52 is held by engaging (not shown).

When the hook 5 is horizontally transferred by the chain 6, the guide groove G1 is in a high position, so that the hook portion 52 faces diagonally upward, and the chain sausage S does not fall from the hook 5. not.

On the other hand, the transfer executing means 7 is installed in the area where the rod hooking step D is performed, and the guide groove G2 with which the rollers engage is slanted at the position where the chain sausage S is transferred from the hook 5 to the rod P. It is tilted downward. Therefore, as shown in the hook 5 at the left end, the hook portion 52 rotates clockwise as the hook 5 is transferred and faces diagonally downward, and the joint portion of the chained sausage S is on the slope of the hook portion 52. Sliding down to the rod P.

In this way, the chained sausage S is transferred from the hook 5 to the rod P by the cooperative operation between the hook 5 and the guide grooves G1 and G2 of the transfer executing means 7.

As described above, in the sausage rod hanging device described in Patent Document 1, the cantilevered rod P is transferred in the direction of the chained sausage S suspended from the hook 5, and the tip of the rod is connected to the sausage loop. The chain sausage S is transferred from the hook 5 to the rod P while the rod P is being transferred in the axial direction in the state of being inserted into the rod P.

<Configuration and operation of rod supply device>
Next, the rod supply device according to the present embodiment will be described with reference to FIGS. 1, 2 and 3.

The rod supply device 1 is composed of a rod storage member 11, a rod extraction member 12, a rod alignment member 13, a rod detection member 14, a rod guide member 15, a rod mounting stand 16, an outlet 17, and a rod transfer member 18. As shown in FIG. 2, these members are arranged in pairs on the left and right sides of the rod supply device 1 while being supported by the housing 10.

A drive means such as a motor or a cylinder is housed in the box in contact with the housing 10 of FIG. 2, but is omitted for the sake of avoiding complexity. For the same reason, some members of the rod supply device 1 (rod storage member 11, rod discharge shutter 23, etc.) are also omitted.

The rod storage member 11 is formed by bending the tip of a stainless steel plate, and stores a plurality of rods P. The rod taking-out member 12 takes out one rod P from the storage place of the rod P, and two grooves 121 for accommodating the rod P are formed on the outer peripheral portion of the disk.

A motor 123 and a position sensor 124 (see FIG. 3) are attached to the rotating shaft 122 of the rod extraction member 12, and when the rod extraction member 12 is rotated by the motor 123 in the arrow direction around the shaft 122, the rod is stored. The rod at the bottom of the rod P stored in the member 11 enters the groove 122.

The rod P is transferred clockwise with the rotation of the rod extraction member 12, then falls from the groove 121 by its own weight, and is guided to the outlet 17 formed between the rod guide member 15 and the rod mounting table 16. It is housed in the recess 181 of the rod transfer member 18.

An air cylinder 183 (see FIG. 3) is connected to the rotating shaft 182 of the arm-shaped rod transfer member 18, and when the air cylinder 183 is extended, the rod transfer member 18 is connected to the rod transfer member 18 as shown by a two-dot chain line in the figure. It turns clockwise around the shaft 182. Along with this, the rod P housed in the recess 181 of the rod transfer member 18 is placed in the recess 321 of the rod mounting member 32 which is a part of the rod gripping means 3.

Since the rod gripping means 3 grips one end of the rod P, the rod transfer member 18 arranged on the inner side of the paper surface maintains the state in which the rod P is housed in the recess 181.

The rod alignment member 13 arranged along the rod extraction member 12 assists the rod P to enter the groove 121 of the rod extraction member 12 in an aligned state, and has an arc shape.

Further, a rod detecting member 14 is installed above the rod taking out member 12, and detects whether or not the rod P is housed in the groove 121 of the rod taking out member 12. The detection result is displayed on the touch panel 84 of the controller 8 shown in FIG.

The rod posture holding member 123 shown in FIG. 2 is composed of a disk having a diameter substantially equal to the bottom of the groove 121 formed in the rod extraction member 12, and is attached to the rotating shaft 122 of the rod extraction member 12. The rod posture holding member 123 prevents the rod P from becoming slanted during the transfer of the rod by the rod take-out member 12 and hindering the transfer to the rod transfer member 18.

Next, the configuration of the control system will be described with reference to FIG. The control system of the rod supply device 1 includes a motor and a cylinder for driving each of the rod extraction member 12, the rod detection member 14, and the rod transfer member 18, and a controller 8 for controlling the operation of these members.

The rod extraction member 12 includes a motor 123 for rotating the disk and a position sensor 124 for detecting the rotation position of the disk, and the controller 8 controls the rotation of the motor 123 according to the output signal of the position sensor 124, and the rod P is taken out from the rod storage member 11 and transferred to the take-out port 17.

When the rod P passes, the rod detecting member 14 is pushed by the rod P and rotates, detects that the rod P is housed in the groove 121, that is, the rod P is taken out from the storage location, and the controller 8 Notify to.

The cylinder 183 of the rod transfer member 18 rotates the rod transfer member 18 and transfers the rod P received at the outlet 17 to the rod mounting member 32.

The control system shown in FIG. 3 further includes a motor and a cylinder for driving each of the rod support arm 21, the bending amount measuring member 22, and the rod discharging shutter 23 constituting the rod bending amount measuring means 2. Will be described later.

The controller 8 controls the operation of each part of the rod supply device 1 and the operation of the rod bending amount measuring means 2 described later, and is composed of a control unit 81, a determination unit 82, a storage unit 83, a touch panel 84, and a power supply 85. There is.

Although not shown, the controller 8 has a built-in CPU, ROM, and RAM, and realizes the respective functions of the control unit 81 and the determination unit 82 by reading the program stored in the ROM and executing the program on the CPU. There is.

The control unit 81 adjusts the rotational position of the rod take-out member 12 by rotating the motor 123 based on the control data stored in the storage unit 83, and the position of the rod transfer member 18 by controlling the cylinder 183. To adjust. Further, as will be described later, the operation of the rod support arm 21, the bending amount measuring member 22, and the rod discharge shutter 23 is controlled.

The determination unit 82 compares the bending amount of the rod measured by the bending amount measuring member 22 described later with the reference value stored in advance in the storage unit 83, and determines the quality of the rod. The determination method will be described in detail later with reference to the drawings.

The storage unit 83 is usually composed of a non-volatile memory such as a flash memory, and stores data necessary for controlling the rod extraction member 12 and the bending amount measuring member 22, and measurement data by the bending amount measuring member 22.

The touch panel 84 is composed of a liquid crystal display, is used for inputting data necessary for controlling the rod extraction member 12 and reference value data necessary for determining the bending amount of the rod, and also displays measurement data and determination results. Used for.

The power supply 85 is connected to an external commercial power supply 86, and supplies power necessary for the operation of each part via a cable (not shown).

<Structure and operation of rod bending amount measuring means>
Hereinafter, the rod bending amount measuring means 2 for measuring the bending amount of the rod, which is incorporated in the rod supply device 1, will be described with reference to FIGS. 1 to 3 and the new FIGS. 5 and 6.

As described with reference to FIG. 4, the sausage rod hanging device described in Patent Document 1 transfers the cantilevered rod P in the direction of the chained sausage S suspended from the hook 5, and moves the tip of the rod. The sausage is transferred from the hook 5 to the rod P while being inserted into the sausage loop.

Therefore, if the rod delivered from the rod supply device 1 to the rod gripping means 3 is bent, the tip of the rod will come off the loop of the chain sausage S when the rod P is transferred in the horizontal direction, and the rod hooking fails. There is a risk of doing. Therefore, in the present embodiment, the means 2 for measuring the bending amount of the rod is incorporated in the rod supply device 1, and the rod having a large bending amount is prevented from being handed over to the rod gripping means 3.

As shown in FIG. 1, the rod bending amount measuring means 2 includes a pair of rod support arms 21, a bending amount measuring member 22, and a pair of rod discharging shutters 23.

The rod P taken out from the storage location and housed in the groove 121 of the disc-shaped rod extraction member 12 is transferred clockwise by the rotation of the rod extraction member 12 and comes into contact with the rod detection member 14. The rod detection member 14 detects the rod P by rotating the arm, and transmits the signal to the controller 8. The rod taking-out member 12 stops rotating at the position shown in FIG. 1 according to the instruction of the controller 8.

The pair of rod support arms 21 having a recess 211 at the tip for accommodating the rod P and being swivel around the shaft 212 are kept in a state where the tip hangs down when not in operation, but the rod extraction member 12 keeps the rod in a hanging state. When P is transferred and stopped above, it turns clockwise as shown by the two-dot chain line in FIG. 1, accommodates the rod P in the recess 211, further turns to the position shown by the solid line, and then stops.

FIG. 5 is a side view of the positional relationship between the rod P, which is lifted upward by the rod support arm 21 and is horizontally supported, and the bending amount measuring member 22. Both ends of the rod P face the bending amount measuring member 22 with a slight gap between them.

As shown in FIGS. 1 and 5, the bending amount measuring member 22 has a pair of sub-plates 222 attached to the side surface of the rectangular base plate 221 via bolts and nuts at regular intervals. .. A light source (LED) 223 is attached to the back surface of one sub-plate 222, and an optical sensor 224 is attached to the back surface of the other sub-plate 222. The tip of the rod P is inserted into the space formed between the sub-plates.

The main plate 221 is attached to the housing 10 of the rod supply device 1 in a state where it can rotate in a vertical plane about the shaft O, and as shown in FIG. 2, the rear surface of the housing 10 is used for driving. Motor 225 is fixed.

As shown in FIG. 1, when the rod support arm 21 rises, the bending amount measuring member 22 is held in a horizontal state, and the sub-plates 222 are located on the left and right. Therefore, the tip of the rod P is inserted into the space between the sub-plates, and there is no problem in turning the rod support arm 21. After that, this state is maintained until the measurement of the bending amount is completed.

A parallel light having a width substantially equal to the diameter of the rod P is emitted from the light source 223, and the parallel light is partially shielded by the rod P existing in the middle and then incident on the optical sensor 224. A method of measuring the bending amount of the rod will be described with reference to FIGS. 5 and 6.

In FIG. 5, the two-dot chain line shows a straight rod without bending, and the solid line shows a rod with a bent center, and the left and right ends are displaced upward compared to the straight rod. ing.

In the present embodiment, the displacement amount of the rod is measured by the bending amount measuring member 22 installed near the left and right ends of the rod, and the bending amount of the rod is determined from the magnitude of the value.

A method of measuring the bending amount of the rod using the bending amount measuring member 22 will be described with reference to FIG. 6 (a) to 6 (c) show the positional relationship between the rod P horizontally supported by the pair of support arms 21 and the bending amount measuring member 22 installed near the end of the rod P.

As shown by the arrow, the main plate 221 of the bending amount measuring member 22 is configured to be able to rotate 180 degrees in the vertical plane about the axis O. Further, the shaft O is aligned with the axis of the rod when a straight rod P without bending is supported by a pair of rod support arms 21.

FIG. 6A shows a state in which a straight rod without bending is supported by a pair of rod support arms 21, and the axis of the rod P coincides with the rotation axis O of the bending amount measuring member 22. Therefore, all the light emitted from the light source 223 (indicated by the arrow) is blocked by the rod P, and the light reaching the optical sensor 224 becomes zero. This state does not change even if the main plate 221 is rotated 180 degrees.

FIG. 6B shows a state in which the central portion of the rod P is lowered downward and both end portions are displaced upward, as shown by the solid line in FIG. Since the end of the rod P is displaced upward, the lower part of the parallel light radiated from the light source 223 is not blocked by the rod P, reaches the optical sensor 224, and has a size corresponding to the amount of displacement. Output signal is obtained. When the main plate 221 is rotated 180 degrees, the maximum output signal is obtained for the optical sensor at 0 degrees and 180 degrees, that is, when the light beam is emitted horizontally.

FIG. 6C shows a state in which the central portion of the rod P is bent in the horizontal direction, and conversely, both end portions are displaced to the opposite sides. When the rod is bent, normally, as shown in FIG. 6B, the central portion of the rod is displaced downward, but depending on the bent state, it may be displaced in the horizontal direction.

When the rod is bent in the horizontal direction, as shown by the solid line in FIG. 6 (c), all the light rays emitted from the light source are blocked by the rod P and the optical sensor 224, as in the case where the rod is straight. Not reachable.

However, as shown by the two-dot chain line, when the main plate 221 is rotated 90 degrees, the positional relationship between the rod P and the light source 223 becomes the same as the positional relationship shown in FIG. 6 (b), so that the output is output to the optical sensor 224. A signal is generated.

As described above, when the main plate 221 of the bending amount measuring member 22 is rotated 180 degrees, the maximum value of the output signal of the optical sensor 224 corresponds to the bending amount of the rod. Therefore, the relationship between the bending amount of the rod P and the output signal of the optical sensor 224 is investigated in advance, the output signal of the optical sensor 224 corresponding to the maximum bending amount that can be used is specified, and the value is stored in the storage unit of the controller 8. Stored in 83.

Every time one rod P is taken out from the storage place by the rod taking-out member 12, the output signal of the optical sensor 224 is detected by using the rod bending amount measuring means 2. Then, by comparing the detected value with the reference value read from the storage unit 83 in the determination unit 82, it can be determined whether or not the value is inappropriate for the rod hanging.

In this embodiment, the bending amount measuring member 22 is installed near both ends of the rod P. This takes into consideration that the position and shape of the bend vary depending on the rod, and the larger value of the output signals detected by the left and right optical sensors 224 is compared with the reference value. However, although the accuracy is slightly lowered, if the bending amount measuring member 22 is installed only in the vicinity of one end of the rod, the configuration of the rod bending amount measuring means 2 can be simplified.

The rod P whose bending amount has been measured by the rod bending amount measuring means 2 is returned to the groove 121 of the rod taking-out member 12 by reversing the rod support plate 21, and is transferred to the take-out port 17. The controller 8 closes the outlet 17 by driving the cylinder 231 of the shutter 23 for the rod P for which the bending amount is determined to exceed the reference value by the measurement by the rod bending amount measuring means 2.

When the outlet 17 is closed by the shutter 23, the rod P slides downward on the inclined portion of the rod mounting table 16 due to its own weight, and is held by the tip portion formed in a hook shape. It is then discarded as an improper rod, or after straightening the bend, it is returned to the rod storage area.

On the other hand, as a result of the measurement by the rod bending amount measuring means 2, the rod P whose bending amount is determined to be within the reference value is transferred to the recess 181 of the rod transfer member 18 through the outlet 17, and the rod gripping means. Handed over to 3. With reference to FIG. 1, after being handed over to the rod gripping means 3, the rod transfer means 4 briefly transfers the rod to the position where the chain sausage S is transferred from the hook 5 (see FIG. 4). explain.

<Gripping and transferring the rod>
On the right side of FIG. 1, the appearance of the rod gripping means 3 and the cross section of the rod transferring means 4 are shown. The rod gripping means 3 grips one end of the rod P, and is a housing 31 attached to the lower end of the bracket 44 of the rod transfer means 4, a rod mounting member 32 attached to the housing 31, and a rod. It is composed of a grip member 33. Although not shown, an actuator for rotating the rod gripping member 33 is housed in the housing 31.

As described above, as the rod transfer member 18 turns, the rod P is transferred from the recess 181 of the rod transfer member 18 to the recess 321 of the rod mounting member 32. After that, as shown by the alternate long and short dash line in FIG. 1, the rod gripping member 33 is rotated counterclockwise, and one end of the rod P is gripped by the rod mounting member 32. As a result, the rod P is gripped in a cantilevered state by the rod gripping means 3.

Next, the rod transfer means 4 will be described. The housing 40 of the rod transfer means 4 is fixed to the housing 10 of the rod supply device 1 by using bolts and nuts. A long bracket 41 is fixed to the bottom of the housing 40 by a metal fitting (not shown), and a rail 42 is attached to the side surface of the bracket 41. A slider 43 slidable along the rail is attached to the rail 42, and a bracket 44 for supporting the housing 31 of the rod gripping means 3 is attached to the back surface of the sudaida 43.

An endless timing belt 45 is arranged in parallel with the rail 42 in the internal space of the housing 40, and both ends are wound around a pair of timing pulleys 46. Although not shown, a motor is attached to the rotation shaft of the timing pulley 46, and the timing belt 45 moves in a direction parallel to the rail 42 due to the rotation of the motor.

As shown in FIG. 1, since the bracket 44 is attached to the timing belt 45 by the connecting member 47, the bracket 44 and the slider 43 move horizontally along the rail 42 as the timing belt 45 moves. ..

Therefore, in the cantilevered rod P whose one end is gripped by the rod mounting member 32 and the rod gripping member 33, when a motor (not shown) rotates and the timing belt 45 moves, the rod P is moved. It is transferred in the axial direction (that is, in the horizontal direction) and is used for hanging the chain sausage S on a rod.

As described above, the rod bending amount measuring means 2 according to the present embodiment is radiated from the light source 223 by the measuring members 22 installed near both ends of the rod P horizontally supported by the pair of rod support arms 21. The amount of parallel light rays blocked by the rod P is detected, and the amount of bending of the rod P is measured based on the value.

The bending amount measuring member 22 has a simple structure and can be inexpensively manufactured by using a commercially available member. Further, it can be realized only by attaching an arm 21 that supports the rod P and a shutter 23 that prevents the rod P from being taken out in the middle of the transfer path of the rod P in the rod supply device 1, and can be retrofitted to the existing rod supply device 1. Since it can be installed by the above, there is a great merit in practical use.

The configuration of the rod supply device and the rod bending amount measuring means is not limited to those shown in the figure. Other configurations may be adopted as long as they can realize the same function. For example, in the present embodiment, a disk having a groove is used as the rod extraction member, but the rod may be taken out by using two shutters installed in close proximity to each other.
