Description

Technical Field

[0001] Embodiments of the present invention relate to a thread insert arranging device and a thread inserting method using the thread insert arranging device. Background Art

[0002] Generally, when high-strength internal threads are required, such as when durability of the internal threads is required or when tightening is required, screw inserts such as coil screw inserts and threaded screw inserts are used. The screw insert is formed by winding a wire such as stainless steel into a coil shape, and is screwed into (buried) a screw hole (threaded hole) of a workpiece such as a resin or an aluminum alloy by a screw insert tool.

[0003] Moreover, a tail handle bent along the diameter direction of the coil is formed at the end of the screw sleeve, for example. When inserting the screw sleeve with the tail handle into the screw hole, the user uses a screw sleeve insertion tool, clamps the tail handle with the front end of the screw sleeve insertion tool, or hooks the front end of the screw sleeve insertion tool on the tail handle. Then, in this state, the screw sleeve is rotated via the tail handle to be screwed into the screw hole.

[0004] Thus, the tail handle is used when inserting the screw sleeve into the screw hole, and the tail handle is no longer needed after the screw sleeve is inserted. If the tail handle is left, it may hinder the entry of the external thread when tightening. Therefore, the tail handle needs to be broken off and removed after the screw sleeve is inserted.

[0005] On the other hand, there is also a screw sleeve that does not have a tail handle and does not need to be broken after the screw sleeve is inserted. When such a screw sleeve that does not have a tail handle (hereinafter, such a screw sleeve is appropriately described as a "screw sleeve without a tail handle") is screwed into a screw hole, a claw hook provided at the front end of a screw sleeve insertion tool is hooked on a notch formed at the end of the screw sleeve without a tail handle to rotate the screw sleeve without a tail handle.

[0006] Specifically, when using a tool equipped with a shankless spiral coil insert (shankless screw insert) disclosed in the above-mentioned patent document 1, an operator rotates a crank handle arranged at the end opposite to the end on which the shankless screw insert is installed to insert the shankless screw insert into the workpiece.

[0010] Technical problem to be solved by the invention

[0011] However, when the number of screw holes formed on the workpiece is large, the number of shankless screw inserts screwed into the screw holes is also large. Moreover, depending on the workpiece, the number of shankless screw inserts screwed in may exceed 100, and it is very laborious for the operator to screw them all in manually. In order to avoid such undesirable situations, in recent years, the assembly tools for screwing shankless screw inserts into screw holes have been electrified, which reduces the labor of the operator.

[0012] Here, no matter the assembly tool is manual or electric, when the screw sleeve is screwed into the workpiece, it is necessary to install the screw sleeve at the front end of the assembly tool (mandrel) in advance. In the case of a manual assembly tool, the screw sleeve is installed on the assembly tool by the operator rotating either the mandrel or the screw sleeve by hand.

[0013] On the other hand, when the assembly tool is electric, the operator holds the screw sleeve with one hand, makes the spindle of the electric assembly tool held in the other hand contact with the end of the screw sleeve and rotates the spindle, thereby installing the screw sleeve on the spindle. Then, the operator needs to hold the screw sleeve while rotating the spindle. This is because if the screw sleeve is not held, the screw sleeve will rotate with the rotation of the spindle.

[0014] Thus, in order to prevent the co-rotation of the screw sleeve, the screw sleeve must be held, but the spindle rotates in a position very close to the hand of the operator holding the screw sleeve. Therefore, the hand holding the screw sleeve and the spindle may not necessarily not accidentally touch each other. In addition, in the case where the screw sleeve is held in a gloved state, it is conceivable that the rotating spindle will entangle the gloves when the screw sleeve is installed.

[0015] Although the screw insert has a variety of sizes, the smaller the size of the screw insert, the closer the position of the hand holding the screw insert and the rotating spindle is when the screw insert is installed on the electric assembly tool. Therefore, there is a concern about contact between the two.

[0016] The present invention provides a screw sleeve arranging device and a screw sleeve inserting method using the screw sleeve arranging device, which can eliminate the danger when installing the screw sleeve on the screw sleeve inserting tool, prevent the co-rotation of the screw sleeve during installation, and reliably install the screw sleeve on the screw sleeve inserting tool.

[0017] In addition, a sleeve arranging device capable of easily managing the number and insertion of sleeves when inserting a large number of sleeves into a workpiece, and a sleeve insertion method using the sleeve arranging device are provided.

[0018] Technical solutions for solving technical problems

[0019] The screw sleeve arrangement device in the embodiment of the present invention comprises: an upper surface formed with arrangement holes for arranging the screw sleeves; and a co-rotation prevention component arranged in the lower layer of the upper surface and in contact with the entire circumference of one end of the screw sleeve placed inside the arrangement hole.

[0020] The co-rotation preventing component in the above-mentioned screw insert arranging device is formed of an elastic body, and a receiving portion is formed on the co-rotation preventing component, which receives the front end portion of the screw insert insertion tool inserted into the arranging hole to install the screw insert.

[0021] The distance from the surface of the arrangement holes of the screw insert arrangement device at the upper surface to the surface where the upper surface contacts the co-rotation prevention member is set according to the type of screw inserts to be arranged.

[0022] Around the upper surface of the screw sleeve arrangement device, a wall is provided, which prevents the screw sleeve of input from falling from the upper surface when the screw sleeve is input and arranged. In addition, the upper surface and the corotation prevent parts from being formed to be able to tilt when discharging the remaining screw sleeve that does not enter the arrangement hole.

[0023] A part of the wall of the insert arranging device is formed to become an opening when the excess inserts are discharged, or the wall is formed so that the entire wall can slide along the surface of the upper surface when the excess inserts are discharged.

[0024] The upper surface of the screw sleeve arrangement device and the corotation preventing component constitute a corotation preventing box, which is formed to be detachable relative to the screw sleeve arrangement device. Moreover, the corotation preventing box also has an adjustment plate, which is the lower layer of the corotation preventing component, and the corotation preventing component is clamped between the adjustment plate and the upper surface.

[0025] In this co-rotation preventing box, no matter how the distance from the surface of the upper surface to the co-rotation preventing component is set according to the type of the screw sleeve, the distance from the upper surface to the adjustment plate is constant. In addition, a fixing portion is formed on the adjustment plate, and the fixing portion protrudes toward a side opposite to a side of the configuration co-rotation preventing component.

[0026] The co-rotation prevention box is installed on the box receiving part in such a way that the adjustment plate is located at a position opposite to the lower surface of the upper part of the base arranged on the screw sleeve arranging device, and the box receiving part is formed between the wall and the lower surface which are designed to prevent the inserted screw sleeve from falling from the upper surface when the screw sleeve is inserted for arrangement.

[0027] The embodiment of the present invention involves a screw inserting method using a screw insert arranging device, comprising: a step of inserting a screw insert into the screw insert arranging device, a step of allowing the inserted screw insert to enter an arranging hole for arranging, a step of discharging the remaining screw insert after arranging from the screw insert arranging device, a step of installing the arranged screw insert on a screw inserting tool, and a step of inserting the installed screw insert into a workpiece.

[0028] In the insert insertion method using the insert arranging device, in the step of mounting the insert on the insert insertion tool, the insert insertion tool mounts the insert in a manner that the insert is pressed toward a travel direction of the insert insertion tool.

[0029] In the insert insertion method using the insert arranging device, in the step of inserting the insert into the workpiece by the insert inserting tool, the insert inserting tool reverses after an insertion time set according to the type of the inserted insert, and ends the inserting action of the insert into the workpiece.

[0030] Furthermore, in the insert insertion method using the insert arranging device, in the step of inserting the insert into the workpiece by the insert inserting tool, the insert inserting tool reverses after inserting the insert to a preset insertion distance, and ends the inserting action of the insert into the workpiece.

[0031] In the insert insertion method using the insert arranging device, the remaining inserts are discharged from the insert arranging device by forming a portion of an opening of a wall surrounding an upper surface on which an arranging hole is formed in the insert arranging device when the insert arranging device is tilted.

[0032] In the insert inserting method using the insert arranging device, the remaining inserts are discharged from the insert arranging device by sliding a wall formed in the insert arranging device to surround the upper surface where the arranging holes are formed on the upper surface.

[0033] In a case where the upper surface and the co-rotation preventing component constitute a co-rotation preventing box, and the co-rotation preventing box can be disassembled and assembled relative to the sleeve arranging device, in a sleeve insertion method using the sleeve arranging device, before the step of inserting the sleeve into the sleeve arranging device, there is a step of installing a co-rotation preventing box corresponding to the type of sleeve installed on the sleeve insertion tool on the box receiving part of the sleeve arranging device.

[0034] Effects of the Invention

[0035] According to the screw sleeve arrangement device in the embodiment of the present invention or the screw sleeve insertion method using the screw sleeve arrangement device, the screw sleeve can be reliably installed on the screw sleeve insertion tool while eliminating the danger of installing the screw sleeve on the screw sleeve insertion tool and preventing the screw sleeve from rotating together during installation. In addition, the number management and insertion management of the screw sleeves when inserting a large number of screw sleeves into the workpiece can be easily performed.

DETAILED DESCRIPTION

[0057] (First Embodiment)

[0058] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0059] Figure 1 1 is a top view showing the overall structure of a screw inserting system S according to an embodiment of the present invention. The screw inserting system S comprises: a screw inserting arrangement device 1, a feeder 2, a recovery device 3 and a screw inserting tool 4. The feeder 2 feeds a screw inserting into the screw inserting arrangement device 1. The recovery device 3 receives the remaining screw inserting discharged from the screw inserting arrangement device 1. The screw inserting tool 4 installs the screw inserting into the screw inserting arrangement device 1 and inserts the screw inserting into a designated place of a workpiece W.

[0060] It should be noted that, as mentioned above, there are two types of thread inserts: thread inserts with tail shanks and thread inserts without tail shanks. In the following description, it is assumed that the thread insert used by the thread insert insertion system S in the embodiment of the present invention is a thread insert without tail shanks. However, thread inserts with tail shanks may also be used.

[0061] The screw sleeve arrangement device 1 is used for arranging the screw sleeve 1 so that the screw sleeve 1 is installed to the screw sleeve insertion tool 4. Therefore, a plurality of tail-free screw sleeves are dropped into the screw sleeve arrangement device 1 from the feeder 2.

[0062] The number of screw sleeves 1 fed from the feeder 2 into the screw sleeve arrangement device 1 is at least the number of screw sleeves to be arranged. Furthermore, it is preferably a number that greatly exceeds the number of screw sleeves to be arranged. Figure 1 The upper surface 11 of the screw sleeve arrangement device 1 shown is formed with 25 arrangement holes 111 as the number for arranging it. Therefore, in this case, since the number of the screw sleeves 1 arranged is 25, the number of the screw sleeves 1 dropped into the screw sleeve arrangement device 1 is more than 25. On the other hand, for example, such a number will not overflow from the upper surface 11 of the screw sleeve arrangement device 1.

[0063] It should be noted that the number of arranged holes here is, for example, the number of arrangement holes 111 formed on the upper surface 11 of the screw sleeve arrangement device 1. Alternatively, when the number of the formed arrangement holes 111 is adjusted using a sealing member described later, it is the adjusted number.

[0064] In addition, when the screw sleeve 1 is put into the screw sleeve arrangement device 1, a mechanism such as a feeder 2 may not be used, and the screw sleeve 1 may be directly put into the screw sleeve arrangement device 1 by an operator, for example.

[0065] A recovery device 3 for receiving the remaining screw sleeves 1 discharged from the screw sleeve arrangement device 1 is disposed adjacent to the screw sleeve arrangement device 1 and directly below the feeder 2. The recovery device 3 can just hold the remaining screw sleeves 1 discharged from the screw sleeve arrangement device 1. Alternatively, a mechanism for connecting the recovery device 3 to the feeder 2 and sending the remaining screw sleeves 1 recovered by the recovery device 3 to the feeder 2 again may be provided.

[0066] The screw sleeve inserting tool 4 is installed on the front end of the mandrel by the screw sleeve 1 arranged in the screw sleeve arranging device 1, and Figure 1 As shown, the screw insert system S moves in the left-right direction, the front-back direction, or the up-down direction. Then, the installed screw insert I is inserted into the screw hole W1 at the designated place of the workpiece W.

[0067] Furthermore, the screw inserting tool 4 used in the embodiment of the present invention is a tool based on power drive, and the operator does not manually insert the screw insert 1 into the workpiece W. It should be noted that as long as it is a tool based on power drive, it can also be an electric type, an engine type, etc., no matter what is used as a power source.

[0068] In addition, the detailed structure of the screw inserting tool 4 is omitted here. The screw inserting tool 4 is a tool commonly used when inserting the screw insert into the workpiece W. Moreover, a mandrel for inserting the screw insert 1 into the screw hole W1 is provided at the front end of the screw inserting tool 4, and a claw for hooking the notch of the screw insert without a tail handle is formed at the front end of the mandrel. The claw is usually in a state of protruding outwardly more than the outer diameter of the mandrel by a force applying member.

[0069] That is, when the shankless screw sleeve is inserted into the screw hole, first, the front end of the mandrel is connected to the other end of the shankless screw sleeve. At this time, the claw is pressed by the inner diameter of the shankless screw sleeve and retracts. Then, in the process of installing the shankless screw sleeve on the mandrel, the claw moves while contacting the inner diameter of the shankless screw sleeve. When reaching the notch portion of the shankless screw sleeve, the claw protrudes due to the force application component and hooks on the notch. Thus, the shankless screw sleeve is fixed and installed on the mandrel.

[0070] Furthermore, a control device for driving and controlling the screw inserting tool 4 is provided inside or outside the screw inserting tool 4. When the screw inserting tool 4 inserts the screw inserting 1 into the workpiece W, the insertion of the screw inserting tool 4 used in the screw inserting system S in the embodiment of the present invention is controlled based on the insertion time or the insertion distance. That is, it can be imagined that when the screw inserting tool 4 inserts the screw inserting 1 into the workpiece W, a part of the screw inserting tool 4 will contact the surface of the workpiece W.

[0071] However, depending on the industry, it is sometimes not desirable to produce scratches (scratches) etc. on the surface of the workpiece W. In such a case, for example, if a part of the screw sleeve insertion tool 4 is detected to contact the surface of the workpiece W and the insertion of the screw sleeve 1 is terminated, scratches cannot be avoided.

[0072] Therefore, in the control of the screw inserting tool 4 in the embodiment of the present invention, the insertion time is predetermined for each type of the screw insert 1. Then, when the predetermined insertion time has passed since the start of insertion, the rotation of the mandrel when inserting the screw insert 1 is reversed, and the insertion of the screw insert 1 into the workpiece W is terminated.

[0073] Alternatively, as a control method for the screw inserting tool 4 in an embodiment of the present invention, it is also considered to control based on the insertion distance instead of the insertion time. That is, when the screw insert 1 is inserted into the workpiece W, the contact position of one end of the screw insert 1 that contacts the workpiece W is used as the reference position, and a detection signal is obtained from a detection sensor, which detects the distance of the screw insert 1 inserted into the workpiece W from the reference position. Therefore, a method of ending the insertion action of the screw insert 1 into the workpiece W when it is determined that a preset insertion distance has been reached can also be adopted.

[0074] In this way, by controlling the screw inserting tool 4 based on either the insertion time or the insertion distance, scratches (scratches) etc. can be effectively prevented from being generated on the surface of the workpiece W when the screw insert 1 is inserted into the workpiece W.

[0075] The workpiece W is an object for the screw sleeve I to be inserted into. Figure 1 For example, three screw holes W1 are formed on the workpiece W, and screw sleeves I are inserted into these screw holes W1. Figure 1 In the workpiece W shown, a screw sleeve I is inserted into one of the three screw holes W1 formed. The diameter of the screw hole W1 is smaller than the diameter of the screw sleeve I.

[0076] Next, the threaded insert arranging device 1 according to the embodiment of the present invention will be described in more detail. Figure 2 1 is a perspective view showing a screw sleeve arrangement device 1 according to an embodiment of the present invention. Figure 3 Cut along line AA Figure 2 FIG. 1 is a cutaway cross-sectional view showing a screw insert arranging device 1 according to an embodiment of the present invention.

[0077] As described above, the threaded sleeve arranging device 1 in the embodiment of the present invention is used to arrange the threaded sleeve 1 so as to install the threaded sleeve 1 on the front end of the mandrel of the threaded sleeve insertion tool 4.

[0078] like Figure 2 or Figure 3 As shown, the screw sleeve arrangement device 1 is composed of an arrangement portion 10 for arranging the screw sleeves 1 and a base 20 supporting the arrangement portion 10. The arrangement portion 10 is further divided into three layers, and is provided with an upper surface 11, a lower surface 12 and a co-rotation preventing component 13.

[0079] The upper surface 11 is provided with an arrangement hole 111 for arranging the screw sleeve 1. The lower surface 12 serves as a base for supporting the upper surface 11 and the co-rotation preventing component 13 described below. In addition, the co-rotation preventing component 13 is sandwiched between the upper surface 11 and the lower surface 12 to prevent the screw sleeve 1 from rotating when the screw sleeve 1 is mounted on the mandrel of the screw sleeve insertion tool 4.

[0080] like Figure 2 or Figure 3 As shown, the screw sleeve arrangement device 1 is formed with a plurality of arrangement holes 111, and the arrangement holes 111 are used to arrange the screw sleeves 1 put into the upper surface 11. The arrangement holes 111 are holes formed for arranging the screw sleeves 1. The screw sleeves 1 are arranged in a manner that can be installed on the screw sleeve insertion tool 4 by entering the arrangement holes 111 through the screw sleeves 1.

[0081] That is, in the screw insert arrangement device 1 in the embodiment of the present invention, the screw insert 1 is arranged by entering the arrangement hole 111 in an upright manner in the up-down direction in the screw insert arrangement device 1. It should be noted that, hereinafter, the end of the screw insert 1 located on the inner side of the arrangement hole 111 in the screw insert 1 entering the arrangement hole 111 is expressed as one end, and the end on the opposite side is expressed as the other end.

[0082] In addition, as mentioned above, the screw sleeve 1 that does not enter the arrangement hole 111 is recovered by the recovery device 3, so the quantity of the arrangement hole 111 represents the quantity of the arranged screw sleeve 1. Therefore, the arrangement hole 111 also possesses the function of the number management of the screw sleeve 1.

[0083] The arrangement hole 111 is formed to penetrate the upper surface 11 in the up-down direction. In addition, a tapered portion 111a is formed on the surface opposite to the surface where the upper surface 11 contacts the co-rotation prevention member 13 (hereinafter, this surface is referred to as the "surface"). The surface portion of the arrangement hole 111 is formed in a tapered shape to facilitate the screw sleeve 1 put into the arrangement portion 10 to enter the arrangement hole 111.

[0084] like Figure 3 As shown, one end of the tapered portion 111a is continuous with the surface of the upper surface 11, and the other end is continuous with the receiving portion 111b into which the screw sleeve 1 actually enters. Moreover, the receiving portion 111b is formed to penetrate the upper surface 11 until it is connected to the co-rotation preventing component 13 in the up-down direction.

[0085] It should be noted that, about the inclination of the tapered portion 111a, no matter how the type of the screw sleeve 1 can be identical. Or, in order to make the screw sleeve 1 enter the arrangement holes 111 more easily, for example, also can be changed by the type of the screw sleeve 1.

[0086] The diameter of the receiving portion 111b in the circumferential direction is formed to a value slightly larger than the diameter of the screw sleeve 1 as the installation object. This is to avoid being difficult to install when the screw sleeve 1 is installed on the screw sleeve insertion tool 4. That is, if the diameter of the receiving portion 111b is much larger than the diameter of the screw sleeve 1, the screw sleeve 1 will be greatly movable in the receiving portion 111b due to the rotation of the mandrel when the screw sleeve 1 is installed on the screw sleeve insertion tool 4.

[0087] therefore, Figure 3The diameter L1 of the receiving portion 111b in the circumferential direction shown in the cross-sectional view is larger than the diameter of the screw sleeve 1 as the installation object. Moreover, the diameter L2 at one end of the tapered portion 111a in contact with the surface of the upper surface 11 is a value larger than the above-mentioned diameter L1. It should be noted that the diameter at the other end of the tapered portion 111a is the same as the diameter L1 of the receiving portion 111b in the circumferential direction.

[0088] In this way, since the diameter L2 of one end of the tapered portion 111a is formed larger than the diameter L1 of the receiving portion 111b, the screw sleeve 1 can easily enter the arrangement hole 111 for arrangement as described above.

[0089] In addition, the length of the receiving portion 111b in the up-down direction corresponds to the length of the long side direction of the screw sleeve 1 as the installation object before installation and is determined. This is because, when the length of the receiving portion 111b in the up-down direction is too long (too deep) compared with the length of the long side direction of the screw sleeve 1, the screw sleeve insertion tool 4 cannot install the screw sleeve 1. Therefore, the length (height) H of the upper surface 11 in the up-down direction is different according to the type of the screw sleeve 1, and is formed to a length that matches each screw sleeve 1.

[0090] Therefore, according to the diameter of the above-mentioned screw sleeve 1, the size of each part of the arrangement hole 111 is also different according to the type of the screw sleeve 1. Therefore, the arrangement portion 10 is prepared according to the type of the screw sleeve 1.

[0091] Therefore, by removing the hinge 40, selecting and assembling the arrangement portion 10 prepared according to the type of the screw sleeve 1, the screw sleeve arrangement device 1 in which the base 20 can cope with the types of various screw sleeves 1 can be obtained.

[0092] It should be noted that, instead of replacing the entire arrangement portion 10 like this, a plurality of upper surfaces 11 or a combination of the upper surface 11 and the co-rotation preventing member 13 made according to the type of the screw sleeve 1 may be prepared in advance, and an appropriate upper surface 11 may be selected according to the type of the screw sleeve 1 used and embedded in the arrangement portion 10. By making only the upper surface 11 the object of replacement like this, it can be used more reasonably than replacing the entire arrangement portion 10. It should be noted that, regarding one aspect of this point, the embodiment will be described again.

[0093] As mentioned above, in the screw sleeve arrangement device 1 in the embodiment of the present invention, be formed with 5 rows of front-back direction, 5 rows of left-right direction, 25 arrangement holes 111 in total.Therefore, the quantity of the screw sleeve 1 arranged in this screw sleeve arrangement device 1 is 25.

[0094] But, can freely set the quantity of the screw sleeve 1 that it is arranged.That is, the quantity of the arrangement holes 111 that is originally arranged on the upper surface 11 is not limited to 25, can be set to various quantities to form.In addition, also can set the quantity of the arrangement holes 111 by other methods.

[0095] Figure 4 1 is a top view showing a state where the sealing member 30 is assembled to the screw sleeve arrangement device 1 in the embodiment of the present invention. Figure 5 FIG. 1 is a top view showing a state where another sealing member 31 is assembled to the screw sleeve arrangement device 1 in the embodiment of the present invention. Figure 4 as well as Figure 5 In the figure, the depiction of the holding portion 60 is omitted.

[0096] Figure 4 The sealing member 30 shown is formed so as to be able to close one arrangement hole 111. Therefore, it is in the shape of a cover, for example, so as to be able to fit into one arrangement hole 111. Figure 4 The sealing member 30 shown in the figure can only block one arrangement hole 111 due to its shape. However, for example, a plurality of sealing members 30 may be connected in a row so that the arrangement holes 111 corresponding to the number of connected sealing members 30 can be blocked.

[0097] exist Figure 4 In the figure, the screw sleeve 1 is shown to enter the inside of each arrangement hole 111 of the screw sleeve arrangement device 1 and be arranged. And, the arrangement hole 111 is formed with 25, and the sealing component 30 is embedded in the arrangement hole 111 at the center. Therefore, the screw sleeve 1 does not enter the arrangement hole 111 embedded with the sealing component 30. As a result, 25 arrangement holes 111 are formed, but the number of the screw sleeves 1 arranged is 24.

[0098] In addition, like Figure 5 As shown in the sealing member 31, the sealing member, for example, can also be formed in a plate shape, which can block the amount of, for example, one row of the arrangement holes 111 arranged on the upper surface 11. In the case of the sealing member 31, it is fixed by a fixing portion not shown in the figure, so that during the period when a plurality of screw sleeves 1 are put into the screw sleeve arrangement device 1 and arranged in the arrangement holes 111, the sealing member 31 is inactive.

[0099] exist Figure 5 In the screw sleeve arrangement device 1 shown, 25 arrangement holes 111 are also formed in 5 rows in the front-back direction and 5 columns in the left-right direction, and a sealing component 31 is configured in a manner of blocking the full column of the 3rd row in the front-back direction. By configuring such a sealing component 31 in the arrangement hole 111, the number of the arranged screw sleeves 1 is 20.

[0100] Like this, by adopting the sealing member that can adjust the arrangement hole 111 formed in the screw sleeve arrangement device 1 to any number, even when the number of screw sleeves 1 as units is different according to the difference in the country, region, and industry in which the screw sleeve arrangement device 1 is used, it is possible to flexibly cope with it. Therefore, the versatility of the screw sleeve arrangement device 1 can be further improved.

[0101] Next, the lower surface 12 is described. The lower surface 12 serves as a base for supporting the upper surface 11 and the co-rotation prevention member 13 described below. In addition, the lower surface 12 is arranged at a position opposite to the mounting surface 21 of the base 20, and the co-rotation prevention member 13 is sandwiched between the lower surface 12 and the upper surface 11.

[0102] Moreover, in the screw sleeve arrangement device 1 in the embodiment of the present invention, for example Figure 1 As shown, the lower surface 12 is connected to the mounting surface 21 by a hinge 40. By connecting the lower surface 12 and the mounting surface 21 at such a position, as described above, the entire arrangement portion 10 can be tilted at the portion of the hinge 40 with the front-rear direction of the screw sleeve arrangement device 1 as the rotation axis.

[0103] It should be noted that the lower surface 12 and the upper surface 11 may be formed using various materials such as metal materials, resin materials, etc. In addition, the upper surface 11 and the lower surface 12 may be formed using different materials.

[0104] In addition, the color of the material can be freely selected at the upper surface 11 and the lower surface 12. However, for the upper surface 11, it is preferably formed with a color different from the color of the screw sleeve 1 as the arrangement object, so that it can be distinguished whether the screw sleeve 1 enters the arrangement hole 111. In addition, when the color of the upper surface 11 is selected according to the relationship with the color of the screw sleeve 1 as the arrangement object, the upper surface 11 can be made to be the same color as a whole, or, it is also possible to only make its surface different from the color of the screw sleeve 1.

[0105] Furthermore, for example, the upper surface 11 may be processed to be smooth so that the inserted screw inserts 1 can easily enter the arrangement holes 111, or when the remaining screw inserts 1 are discharged outside the screw insert arrangement device 1, the screw inserts 1 will not be hooked on the surface of the upper surface 11. In addition, the smoothness can also be ensured by using only a different material for the surface of the upper surface 11.

[0106] Co-rotation preventing component 13 is used for the nut sleeve 1 to be easily and reliably installed on the nut sleeve inserting tool 4. Therefore, co-rotation preventing component 13 is formed by an elastomer. Therefore, for example, materials such as polypropylene can be adopted, but more preferably rubber components can be adopted. Because co-rotation preventing component 13 is formed by an elastomer, so co-rotation preventing component 13 can prevent the co-rotation of the nut sleeve 1 when the nut sleeve 1 is installed on the mandrel.

[0107] That is, from the perspective of the size relationship between the arrangement hole 111 and the screw sleeve 1, when the screw sleeve 1 enters the arrangement hole 111 and maintains the arrangement state, the screw sleeve 1 will not be subjected to any force, so that the screw sleeve 1 can move freely in the arrangement hole 111.

[0108] However, when the threaded sleeve 1 is inserted into the threaded sleeve insertion tool 4, during the rotation of the mandrel, if the installed threaded sleeve 1 is not fixed, the threaded sleeve 1 also rotates along with the rotation of the mandrel.

[0109] Therefore, during the action of the screw sleeve 1 being installed in the screw sleeve inserting tool 4, it is necessary to fix in advance so that the screw sleeve 1 does not rotate. Therefore, in the screw sleeve arrangement device 1 in the embodiment of the present invention, the above-mentioned co-rotation preventing component 13 is set. The specific effect is as follows.

[0110] When the screw sleeve 1 enters the arrangement hole 111 and is in the arrangement state, the other end of the screw sleeve 1 is located on the surface side of the upper surface 11, and one end thereof is arranged on the inner side of the arrangement hole 111. Moreover, as described above, the arrangement hole 111 is formed to penetrate the upper surface 11 in the up-down direction, and the upper surface 11 is connected to the co-rotation preventing component 13 on the inner side of the arrangement hole 111. Therefore, one end of the screw sleeve 1 entering the arrangement hole 111 is connected to the co-rotation preventing component 13.

[0111] In this state, the front end of the mandrel contacts the other end of the screw sleeve 1 disposed on the surface side of the upper surface 11, and the screw sleeve 1 is installed on the screw sleeve insertion tool 4.

[0112] That is, the rotating mandrel is inserted from the surface side of the upper surface 11 toward the lower surface 12 sides, and the front end of the mandrel first contacts with the other end of the screw sleeve 1. Afterwards, the screw sleeve 1 is installed on the mandrel in the mode of pressing the screw sleeve insertion tool 4 downward.

[0113] The mandrel is rotated while advancing in the arrangement hole 111 toward the downward direction, so that the screw sleeve 1 is installed on the mandrel. At this time, since the force toward the lower side of the mandrel (screw sleeve insertion tool 4) is applied to the screw sleeve 1, one end of the screw sleeve 1 is pressed on the corotation preventing component 13 in a state of applying a strong force.

[0114] Since the corotation preventing component 13 is made of the material as described above, the rotation of the screw sleeve 1 caused by the rotation of the spindle is suppressed by strongly pressing one end of the screw sleeve 1 against the corotation preventing component 13, thereby preventing corotation.

[0115] In addition, according to the circumstances, it is also possible to imagine that one end of the screw sleeve 1 is sunk into the corotation preventing component 13. If this is the state, the screw sleeve 1 can be further reliably fixed during the screw sleeve insertion tool 4 being installed on the screw sleeve 1.

[0116] Like this, in the screw sleeve arrangement device 1 in the embodiment of the present invention, when the screw sleeve 1 is installed on the screw sleeve insertion tool 4, one end of the screw sleeve 1 located on the inner side of the arrangement hole 111 is fixed by contacting with the co-rotation prevention component 13.

[0117] On the other hand, the diameter L1 of the arrangement hole 111 is larger than the diameter of the screw sleeve 1. Therefore, during the period when the screw sleeve inserting tool 4 installs the screw sleeve 1, the arrangement hole 111 and the screw sleeve 1 are almost not in contact with each other in the middle of the insertion direction of the screw sleeve 1 in the arrangement hole 111. Therefore, when the screw sleeve inserting tool 4 installs the screw sleeve 1, in any area of ​​the long side direction connecting one end of the screw sleeve 1 and the other end, the arrangement hole 111 is not used to fix the screw sleeve 1.

[0118] In addition, the co-rotation preventing component 13 is formed with a receiving portion 131 for receiving the front end of the mandrel inserted into the arrangement hole 111. After the mandrel of the screw sleeve inserting tool 4 enters the arrangement hole 111, the screw sleeve 1 is slowly wound (installed) on the mandrel while entering into the depth of the arrangement hole 111.

[0119] As described above, the screw sleeve 1 used in the embodiment of the present invention is a screw sleeve without a tail handle. In the case of a screw sleeve without a tail handle, the claw hook arranged at the front end of the mandrel is hung on the notch arranged near one end of the screw sleeve without a tail handle. In this way, the screw sleeve 1 can be kept at the front end of the mandrel during the process of inserting the workpiece W, and the screw sleeve 1 can be inserted into the screw hole of the workpiece W while rotating.

[0120] In order to make the claw of the mandrel hook on the notch of the screw sleeve 1, the front end of the mandrel needs to fully enter the depth of the arrangement hole 111 and reach the notch of the screw sleeve 1. However, when the claw becomes the state of hooking on the notch, the front end of the mandrel becomes the state of protruding from one end of the installed screw sleeve 1.

[0121] Here, at the surface where the upper surface 11 and the co-rotation preventing member 13 meet, if the co-rotation preventing member 13 is formed to block the arrangement hole 111, the following undesirable situation will occur: that is, before the claw of the mandrel is hooked on the notch formed near the end of the screw sleeve 1, the front end of the mandrel is prevented from further entering the depth of the arrangement hole 111 by the co-rotation preventing member 13.

[0122] Therefore, in the screw sleeve arrangement device 1 in the embodiment of the present invention, the co-rotation prevention component 13 is provided with a receiving portion 131, and the front end of the mandrel can exceed one end of the screw sleeve 1 connected to the co-rotation prevention component 13 and enter the depth of the arrangement hole 111. In this way, by forming the receiving portion 131 for receiving the front end of the mandrel on the co-rotation prevention component 13, when installing the screw sleeve insertion tool 4, the claw of the mandrel can be reliably hooked on the notch of the screw sleeve 1.

[0123] Therefore, the receiving portion 131 is formed to have a diameter larger than the diameter of the mandrel. Figure 3 As shown, the receiving portion 131 in the embodiment of the present invention is formed to penetrate the co-rotation prevention member 13 in the up-down direction. However, the receiving portion 131 may not be formed to penetrate the co-rotation prevention member 13, for example, the receiving portion 131 may be formed as a recessed portion having a depth capable of accommodating the front end of the spindle.

[0124] The base 20 is composed of a mounting surface 21 on which the arrangement portion 10 is mounted and legs 22 connected to the mounting surface 21 and supporting the entire screw insert arrangement device 1. Furthermore, by connecting the mounting surface 21 to the lower surface 12 via a hinge 40, the base 20 can be attached to and detached from the arrangement portion 10.

[0125] As described above, the arrangement portion 10 and the base 20 can be disassembled like this because the arrangement hole 111 is different according to the size of the screw sleeve 1 as the arrangement object, so it is necessary to replace the arrangement portion 10 according to the type of the screw sleeve 1.

[0126] In addition, since only a part of the arrangement portion 10 and the base portion 20 are connected by the hinge 40 as described above, the arrangement portion 10 can be moved in a direction with the hinge 40 as a base point. Figure 2 The arrangement portion 10 is lifted in the direction of the arrow and tilted toward the hinge 40 side. By lifting the arrangement portion 10 from the base 20 and tilting it like this, the remaining screw sleeves 1 that have not entered the arrangement holes 111 in the inserted screw sleeves 1 can be discharged outside the arrangement portion 10.

[0127] Then, the remaining screw sleeve 1 discharged from the screw sleeve arrangement device 1 is recovered by the recovery device 3. Therefore, when the screw sleeve arrangement device 1 is placed on, for example, a workbench, the distance from the end of the leg 22 arranged on the workbench to the surface of the mounting surface 21 opposite to the lower surface 12 is set according to the relationship with the configuration position of the recovery device 3.

[0128] It should be noted that the size of the mounting surface 21 is formed to be substantially the same as the size (area) of the lower surface 12 of the array portion 10 in the threaded insert array device 1 in the embodiment of the present invention. However, the size can be freely set as long as the array portion 10 can be mounted reliably.

[0129] In addition, regarding the legs 22, four legs are also provided in the insert arranging device 1 in the embodiment of the present invention. However, as long as the arranging portion 10 can be supported reliably, for example, the number and shape thereof can be freely set.

[0130] like Figure 2 , Figure 3As shown, a wall 50 is provided around the upper surface 11 of the threaded sleeve arrangement device 1. That is, since the threaded sleeve arrangement device 1 in the embodiment of the present invention is formed as a quadrilateral, the wall 50 also connects with the upper surface 11 and is arranged on 4 sides in a manner that surrounds the upper surface 11.

[0131] This wall 50 prevents the inserted screw sleeve 1 from falling from the upper surface 11 when the screw sleeve 1 is inserted for arrangement. Therefore, the length (height) of the wall 50 in the up-down direction can be set arbitrarily as long as there is a height at which the screw sleeve 1 will not fall on the outside of the screw sleeve arrangement device 1 when or after the insertion.

[0132] The wall 50 is fixed to the upper surface 11 by inserting a fixing member (not shown) into a fixing hole 50a extending downward from the upper portion of the wall 50. As the fixing member, a screw can be used, for example. The fixing hole 50a only needs to reach at least the upper surface 11, and may be formed to reach the lower surface 12 and be fixed integrally with the arrangement portion 10. The fixing portion is not limited to Figure 2 4 places shown.

[0133] A part of the wall 50 of the screw sleeve arrangement device 1 in the first embodiment of the present invention is formed as an opening wall 51 that becomes an opening when discharging the remaining screw sleeve 1. Then, by tilting the screw sleeve arrangement device 1 and opening the opening wall 51, an opening O is formed between other walls constituting the wall 50.

[0134] Specifically, the opening wall 51 is provided on one of the four sides constituting the wall 50. Therefore, the opening wall 51 is different from the other three sides and is formed by different parts. That is, the three sides are formed into a U-shape, and the remaining one side blocks the open part of the U-shape. Then, the upper part of the one side of the opening wall 51 and the upper parts of the two sides connected to the one side are connected by the hinge 40. By adopting such a structure, when the arrangement part 10 is tilted, the lower part of the opening wall 51 that is not connected is opened to form the opening part O.

[0135] In addition, among the three sides of the wall 50 that do not form the opening wall 51, Figure 2 A holding portion 60 is provided on the wall 50 disposed on the front side. The holding portion 60 is used to tilt the arrangement portion 10 so that the remaining screw sleeves 1 that are put into the arrangement portion 10 and do not enter the arrangement hole 111 are discharged outside the screw sleeve arrangement device 1.

[0136] That is, the operator holds the gripping portion 60 and lifts the arranging portion 10 upward, so that the arranging portion 10 is lifted from the base 20. When the operator further moves the gripping portion 60, the arranging portion 10 rotates about the boundary between the lower surface 12 and the mounting surface 21 connected by the hinge 40 as the axis of rotation. Figure 2 The arrow direction shown is tilted.

[0137] Figure 6 1 is a perspective view showing a state in which the arrangement portion 10 is tilted from the base portion 20 in the screw insert arrangement device 1 according to the first embodiment of the present invention. The screw insert arrangement device 1 becomes Figure 6 The state shown.

[0138] As described above, the opening wall 51 is connected to two of the other three sides of the wall 50 by the hinge 40, and the lower part thereof is not connected and can move freely. Therefore, when the arrangement portion 10 is tilted, the opening wall 51 gradually opens with the connection portion of the opening wall 51 and the wall 50 connected by the hinge 40 as the rotation axis.

[0139] However, since the upper portion of the opening wall 51 is fixed, the opening wall 51 itself does not change its orientation significantly due to gravity, and remains substantially parallel to the vertical direction, similar to the state where the array portion 10 is not tilted. Thus, the opening O is formed by the opening wall 51 being in such a state.

[0140] By tilting the arrangement portion 10 to form the opening O, the remaining screw sleeves I that have not entered the arrangement holes 111 in the arrangement portion 10 are discharged from the arrangement portion 10 to the outside and are received in the recovery device 3. Figure 6 The illustration is omitted.

[0141] [action]

[0142] Next, use Figures 7 to 11 The flow of processing of the insert insertion method using the insert insertion system S in the embodiment of the present invention will be described. Figure 7 It is a flowchart showing the flow of the insert inserting method using the insert arranging device 1 according to the embodiment of the present invention.

[0143] It should be noted that Figure 7 The flowchart shows the process of controlling the screw inserting tool 4 based on the insertion time when the screw inserting tool 4 is used to insert the screw inserting tool 1 into the workpiece W, so the following is explained by taking the case of using the insertion time as an example.

[0144] First, the thread insert I is put into the thread insert arrangement device 1 (ST1). In the thread insert insertion system S in the embodiment of the present invention, thread inserts I having a number greater than the number of arrangement holes 111 formed on the upper surface 11 are put into the thread insert arrangement device 1 from the feeder 2.

[0145] Figure 8 1 is a top view showing a state in which a screw sleeve 1 is put into a screw sleeve arrangement device 1 in a screw sleeve insertion method using the screw sleeve arrangement device 1 according to an embodiment of the present invention. Figure 8 The depiction of the gripping portion 60 is omitted.

[0146] like Figure 8 Shown, just after input, some screw sleeves 1 also can enter the arrangement holes 111, but are not to enter all the arrangement holes 111. In addition, there is also a screw sleeve 1 configured in an overlapping manner without entering the arrangement holes 111.

[0147] Therefore, next, in a manner such as vibrating the entire screw sleeve arrangement device 1 so that the screw sleeve 1 enters all the arrangement holes 111 (ST2), the screw sleeve 1 is made to enter all the arrangement holes 111. Then, the remaining screw sleeve 1 that has not entered the arrangement holes 111 is discharged to the outside of the screw sleeve arrangement device 1 (ST3).

[0148] like Figure 6 As shown, the remaining screw sleeve 1 is discharged by tilting the arrangement portion 10 away from the base 20. By tilting the arrangement portion 10, the opening wall 51 is opened to form an opening O. The remaining screw sleeve 1 is discharged from the opening O to the outside of the screw sleeve arrangement device 1. Then, the discharged remaining screw sleeve 1 is recovered by the recovery device 3.

[0149] Fig. 9 1 is a top view showing a state after the remaining screw inserts are discharged from the screw insert arrangement device 1 in the screw insert insertion method using the screw insert arrangement device 1 according to the first embodiment of the present invention. Fig. 9 In the figure, the feeder 2 and the holding part 60 are omitted.

[0150] like Fig. 9 As shown, the screw sleeve 1 more than the number of arrangement holes 111 is recovered to the recovery device 3 as the remaining screw sleeve 1. On the other hand, in the screw sleeve arrangement device 1 after the remaining screw sleeve 1 is discharged, the screw sleeve 1 enters all the arrangement holes 111 and is arranged.

[0151] In this state, the screw sleeve 1 can be installed on the screw sleeve insertion tool 4. Therefore, the screw sleeve insertion tool 4 is moved to the top of the screw sleeve 1 as the installation object (ST4), and the screw sleeve 1 arranged in the inner part of the arrangement hole 111 is installed on the mandrel (ST5) by descending toward the screw sleeve 1.

[0152] When the screw sleeve 1 is installed on the mandrel, as mentioned above, the screw sleeve insertion tool 4 is downwardly entered into the arrangement hole 111 in the mode of applying force to the screw sleeve 1. At this time, since one end of the screw sleeve 1 is close to the corotation prevention component 13, even if the mandrel rotates, the screw sleeve 1 can be prevented from corotating.

[0153] In addition, since the co-rotation preventing component 13 is formed with a housing 131, the front end of the mandrel entering the deep part of the arrangement hole 111 can advance without being hindered from entering by the co-rotation preventing component 13. Therefore, the claw hook can be reliably hung on the notch of the screw sleeve 1.

[0154] Fig.10 1 is a perspective view showing a state in which the screw inserting tool 4 is installed with the screw inserting tool 4 in the screw inserting method using the screw inserting tool 1 of the screw inserting device 1 according to the embodiment of the present invention. Fig.10 In the figure, the base 20 is omitted.

[0155] like Fig.10 As shown, the screw inserting tool 4 approaches the arranged screw inserts 1 from the top, and installs the screw inserts 1 while rotating the spindle. Fig.10 In, the state that the installation of the screw sleeve 1 to the mandrel is completed is shown. Under this state, the claw hook of the mandrel is hung on the breach of the screw sleeve 1, and the front end of the mandrel is accommodated in the accommodating portion 131.

[0156] Then, the screw sleeve insertion tool 4 that screw sleeve 1 is installed is lifted upward, and screw sleeve insertion tool 4 is moved to the top (ST6) of the screw hole W1 of workpiece W. Then, screw sleeve insertion tool 4 is lowered toward screw hole W1 on one side, and screw sleeve 1 is inserted into screw hole W1 on one side (ST7).

[0157] Fig.11 1 is a perspective view showing a state in which a screw inserting tool 4 is inserted into a workpiece W in a screw inserting method using the screw insert arranging device 1 according to an embodiment of the present invention. Fig.11 The feeder 2 is also omitted in the figure. The screw hole W1 is formed to be smaller than the outer diameter of the screw sleeve I, and the internal thread is arranged on the workpiece W by screwing the screw sleeve I into the screw hole W1.

[0158] In the screw inserting tool 4, it is determined whether a prescribed time (ST8) as the insertion time of the screw insert 1 into the workpiece W has passed. If the prescribed time has not passed (NO in ST8), the insertion is continued because the screw insert 1 is still in the insertion process. On the other hand, if the prescribed time has passed (YES in ST8), the screw inserting tool 4 is lifted up from the screw hole W1 while reversing the mandrel (ST9).

[0159] Then, after confirming whether there is a screw sleeve 1 to be inserted in the screw sleeve arrangement device 1 (ST10), if there is (ST10 is yes), return to step ST4 and perform the above-mentioned process again. On the other hand, if there is no screw sleeve 1 to be inserted (ST10 is no), the insertion process of the screw sleeve of the screw sleeve arrangement device 1 is terminated.

[0160] By adopting the above-described screw insert arrangement device 1 or the screw insert insertion method using the screw insert arrangement device 1, the screw insert can be reliably installed on the screw insert insertion tool while eliminating the danger of installing the screw insert on the screw insert insertion tool and preventing the screw insert from rotating together during installation. In addition, the number management and insertion management of the screw inserts when inserting a large number of screw inserts into the workpiece can be easily performed.

[0161] (Second Embodiment)

[0162] Next, a second embodiment of the present invention will be described. In the second embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and descriptions of the same components are omitted to avoid duplication.

[0163] In the screw sleeve arrangement device 100 in the second embodiment, the structures of the arrangement portion 10 and the base 20 are also the same as those of the screw sleeve arrangement device 1 before this. On the other hand, the screw sleeve arrangement device 100 in the second embodiment is different from the screw sleeve arrangement device 1 in the first embodiment in the method of discharging the remaining screw sleeve 1 to the outside.

[0164] Fig.12 1 is a perspective view showing a thread insert arranging device 100 according to a second embodiment of the present invention. The thread insert arranging device 100 is also similar in that a wall 101 is provided to surround the periphery of the upper surface 11 .

[0165] However, the structure of the wall 101 is different from the structure of the wall 50 in the screw sleeve arrangement device 1. In addition, in the second embodiment, the wall 101 is provided to the screw sleeve arrangement device 1. Fig.12 Slide in the direction of the arrow shown, thereby discharging the remaining screw sleeve I to the outside of the screw sleeve arranging device 100.

[0166] It should be noted that, unlike the wall 50 of the screw sleeve arrangement device 1 in the first embodiment, the wall 101 does not surround the upper surface 11, but is formed into a quadrangular plate-like shape having substantially the same size as the arrangement portion 10. In addition, a circular through hole 101a is formed in the region where the arrangement hole 111 is formed.

[0167] In addition, the bottom surface 101b of the wall 101 is opposite to the surface of the upper surface 11. The bottom surface 101b may be in contact with the surface of the upper surface 11, or may be provided with a space of a degree that does not clamp the remaining screw sleeve 1 between the surface of the upper surface 11 when the screw sleeve 1 inserted is discharged.

[0168] Fig.13 1 is a top view showing a state where the screw sleeve 1 is put into the screw sleeve arrangement device 100 according to the second embodiment of the present invention. Fig.14 1 is a plan view showing a state in which the remaining screw inserts 1 are discharged from the screw insert arranging device 100 according to the second embodiment of the present invention.

[0169] like Fig.13 As shown, the screw sleeve 1 that is put into the screw sleeve arrangement device 100 is as described before, more than the number of arrangement holes 111. Therefore, there are both screw sleeves 1 that enter the arrangement holes 111 and screw sleeves 1 that are not entered and are configured in an overlapping manner. But, owing to the presence of above-mentioned wall 101, even if the number of the screw sleeve 1 that is put into is many, the screw sleeve 1 can not fall outwards from the screw sleeve arrangement device 100 just after putting into.

[0170] Then, the screw sleeve 1 is arranged by making the screw sleeve 1 enter the arrangement hole 111. In addition, the remaining screw sleeve 1 that does not enter the arrangement hole 111 is discharged outside the screw sleeve arrangement device 100. Fig.14 This status is shown.

[0171] like Fig.14 As shown, for example, the operator uses Fig.12 Shown holding portion 60 moves to the direction of arrow, so that wall 101 integral body slides on the surface of upper surface 11. By this wall 101 sliding, remaining screw sleeve 1 is discharged to the recovery device 3 outside the screw sleeve arrangement device 100.

[0172] By adopting the above-described screw sleeve arrangement device 100 or the screw sleeve insertion method using the screw sleeve arrangement device 100, the screw sleeve can be reliably installed on the screw sleeve insertion tool while eliminating the danger of installing the screw sleeve on the screw sleeve insertion tool and preventing the screw sleeve from rotating together during installation. In addition, the number management and insertion management of the screw sleeves when inserting a large number of screw sleeves into the workpiece can be easily performed.

[0173] When the screw sleeve 1 is installed on the screw sleeve insertion tool 4, it is necessary to prevent the screw sleeve 1 from rotating co-rotating with the rotation of the mandrel of the screw sleeve insertion tool 4. That is, the screw sleeve 1 must be fixed during installation on the screw sleeve insertion tool 4. In the screw sleeve arrangement device 1, 100 in the first or second embodiment of the present invention, the co-rotation prevention component 13 is configured in a manner of being sandwiched between the upper surface 11 and the lower surface 12 formed with the arrangement hole 111.

[0174] Therefore, one end of the screw sleeve 1 entering the arrangement hole 111 contacts the corotation preventing component 13. Therefore, the spindle of the screw sleeve insertion tool 4 entering the arrangement hole 111 for installing the screw sleeve 1 presses one end of the screw sleeve 1 to be installed against the corotation preventing component 13, and fixes the screw sleeve 1 by strongly pressing one end of the screw sleeve 1 against the corotation preventing component 13 to prevent corotation.

[0175] On the other hand, because the diameter of the circumferential direction of the arrangement hole 111 is larger than the diameter of the screw sleeve 1, the screw sleeve 1 arranged in the arrangement hole 111 does not contact with the receiving portion 111b. Therefore, when the screw sleeve 1 is installed in the screw sleeve insertion tool 4, it does not help to fix the screw sleeve 1.

[0176] Like this, in the screw sleeve arrangement device 1 in the embodiment of the present invention, in order to prevent the corotation when the screw sleeve 1 is installed on the screw sleeve insertion tool 4, the corotation prevention component 13 is used. Since the screw sleeve 1 is fixed by the hands of the operator, safety can be ensured.

[0177] In addition, by adopting the screw sleeve arrangement device 1, 100 in the first or second embodiment of the present invention, the screw sleeve insertion tool 4 can be continuously installed and lifted upward after being in contact with the other end of the screw sleeve I until it moves to the workpiece W, so the screw sleeve I can be efficiently inserted into the workpiece W.

[0178] (Third Embodiment)

[0179] Next, a third embodiment of the present invention will be described. It should be noted that in the third embodiment, the same components as those described in the first and second embodiments are denoted by the same reference numerals, and the description of the same components is omitted to avoid duplication.

[0180] In the insert arranging device 200 in the third embodiment, unlike the insert arranging devices 1 and 100 described in the first or second embodiment, an example is shown in which at least the upper surface and the corotation preventing member are configured as a detachable corotation preventing box.

[0181] As mentioned above, about the screw sleeve 1, its diameter and number of turns are multiple. In addition, there are screw sleeves 1 with the same diameter but different numbers of turns. Therefore, in the screw sleeve arrangement device 1, 100 in the first and second embodiments before this, it is also a prerequisite to prepare the arrangement portion 10 by the type of the screw sleeve 1.

[0182] However, since the arrangement portion 10 and the base 20 are fixed by the hinge 40, when the arrangement portion 10 is changed according to the screw sleeve 1 as the installation object, the hinge 40 needs to be removed. Therefore, if the arrangement portion 10 can be changed without removing the hinge 40, a variety of screw sleeves 1 can be more easily coped with.

[0183] Therefore, in the insert arranging device 200 according to the third embodiment described below, the arranging portion 10 , particularly the upper surface 11 and the co-rotation preventing member 13 , are configured as a co-rotation preventing box C that is attachable to and detachable from the insert arranging device 200 .

[0184] Fig.152 is a perspective view showing a screw sleeve arrangement device 200 according to a third embodiment of the present invention. Fig.15 In the screw sleeve arranging device 200 shown, the state of having a co-rotation prevention box C installed is shown, and the upper surface for arranging the screw sleeve I can be seen.

[0185] That is, the arrangement portion 10 for arranging the screw sleeve 1 is configured to be detachable relative to the screw sleeve arrangement device 200, and the box receiving portion 70 for receiving the co-rotation prevention box C is formed on the screw sleeve arrangement device 200 side, which is different from the screw sleeve arrangement device 1 and 100 described in the first and second embodiments before this. On the other hand, in addition to this, other structures are the same as the screw sleeve arrangement device 1 and 100 described before this.

[0186] also, Fig.16 The following shows a state where such a screw insert arranging device 200 is viewed from above. Fig.16 FIG. 2 is a top view showing a screw sleeve arrangement device 200 according to a third embodiment of the present invention. Fig.16 In the figure, the chamfering of the corners of the holding portion 60 and the portion of the co-rotation prevention box C protruding from the screw sleeve arrangement device 200 is omitted. Fig.16 , the state in which the screw sleeve 1 enters the arrangement hole 111 is shown.

[0187] on the other hand, Fig.17 1 is a perspective view showing a state where the co-rotation prevention box C is removed from the screw insert arranging device 200 according to the third embodiment of the present invention. Fig.17 In the figure, a box receiving portion 70 for receiving the co-rotation prevention box C in the screw sleeve arrangement device 200 is shown.

[0188] The bottom surface of the box receiving portion 70 is the lower surface 12 described above. And, a wall (insertion wall 71) is provided around the lower surface 12. In the screw sleeve arrangement device 200 in the third embodiment of the present invention, in particular, except for the part of the base 20, it is roughly formed into a rectangular shape. Therefore, the insertion wall 71 is also provided along the three sides of the lower surface 12.

[0189] The reason why the insertion wall 71 is provided only on three sides of the lower surface 12 is that the remaining one side constitutes an insertion port 72 which becomes a receiving port when the co-rotation prevention box C is installed. When the co-rotation prevention box C is inserted into the screw sleeve arrangement device 200, the co-rotation prevention box C is inserted from the insertion port 72 so that the co-rotation prevention box C is pushed toward the screw sleeve arrangement device 200. Figures 15 to 17 Move to the left as shown.

[0190] As described above, the insertion wall 71 is provided on three sides of the lower surface 12 except the insertion opening 72. Fig.15As shown, the distance of the insertion port 72 in the front-rear direction is substantially the same as the distance of the co-rotation prevention box C in the same direction. That is, the size of the insertion port 72 is determined by the insertion wall 71.

[0191] Moreover, if Fig.16 , Fig.17 As shown, two insertion walls 71, 71 extending leftward from the insertion port 72 are parallel to the left and right directions. By forming the insertion walls 71, 71 in this way, the co-rotation prevention box C is inserted into the screw sleeve arrangement device 200 in a manner guided by the insertion walls 71, 71 from the insertion port 72.

[0192] The co-rotation preventing box C inserted into the screw sleeve arrangement device 200 in a manner guided by the insertion walls 71, 71 contacts and stays at the insertion wall 71 disposed at a position opposite to the insertion port 72. That is, by being arranged at the insertion wall 71 at this position, the co-rotation preventing box C cannot move to the left again when inserted.

[0193] As can be seen from the above, the insertion wall 71 in the box receiving portion 70 defines the position of the co-rotation prevention box C in the screw sleeve arrangement device 200 during and after insertion.

[0194] Furthermore, especially Fig.17 As shown, the insertion wall 71 formed on three sides of the lower surface 12 also serves as a base for the wall 50. Here, in the screw insert array device 1, 100 in the first or second embodiment, the wall 50 is formed on the upper portion of the upper surface 11.

[0195] In contrast, in the screw sleeve arrangement device 200 in the third embodiment, the upper surface and the co-rotation preventing member are both configured as a co-rotation preventing box C that can be detached from the screw sleeve arrangement device 200. Therefore, the wall 50 cannot be formed on the upper portion of the upper surface 11. Therefore, the function of the above-mentioned wall 50 is maintained by configuring and fixing the wall 50 on the upper portion of the box receiving portion 70 (insertion wall 71).

[0196] like Fig.17 As shown, on the lower surface 12 corresponding to the bottom surface of the box receiving portion 70, two engaging portions 73, 73 are formed near the insertion port 72. After the co-rotation prevention box C is installed in the screw sleeve arrangement device 200, the engaging portions 73, 73 are engaged with the fixing portions C3a, C3a provided on the co-rotation prevention box C to prevent separation. It should be noted that the fixing portion C3a will be described later.

[0197] Next, the co-rotation prevention box C will be described. Fig.18 A co-rotation prevention box C according to a third embodiment of the present invention is shown. (A) is a plan view, and (B) is a cut-away cross-sectional view obtained by cutting the plan view along line BB.

[0198] like Fig.18As shown in (B), the co-rotation prevention box C is formed into a three-layer structure. From the top to the bottom are the upper surface C1, the co-rotation prevention component C2 and the adjustment plate C3. Here, the functions and structures of the upper surface C1 and the co-rotation prevention component C2 are the same as those of the upper surface 11 and the co-rotation prevention component 13 described in the first and second embodiments.

[0199] That is, Fig.18 (A) and Fig.18 As shown in (B), the upper surface C1 is formed with arranged holes. Moreover, a tapered portion C1a and a receiving portion C1b which is continuous from the tapered portion C1a and receives the screw insert 1 which is the installation object to be installed on the screw insert insertion tool 4 are provided at the portion connected to the surface. The upper surface C1 is prepared according to the type of the screw insert 1, and the diameter and the depth of the receiving portion C1b in the up-down direction are different according to the type of the screw insert 1.

[0200] Regarding the tapered portion C1a and the receiving portion C1b, when the co-rotation prevention box C has been installed at a desired position in the screw sleeve arrangement device 200, as shown in FIG. Fig.16 As shown, it is formed to be arranged in the approximate center of the screw sleeve arranging device 200.

[0201] In addition, the corotation preventing component C2 is formed with a receiving portion C2a for receiving the front end portion of the mandrel on which the screw sleeve 1 is installed. And, about the material of the corotation preventing component C2, it is the same as before, and it is also possible to preferably adopt an elastomer, particularly a rubber component.

[0202] On the other hand, there is a difference in size between the upper surface C1 and the co-rotation preventing member C2. Fig.18 As is apparent from the cut-away cross-sectional view of (B), the upper surface C1 is larger than the co-rotation preventing member C2 in the left-right direction.

[0203] That is, Fig.18 As shown in (B), when the ends on the left side of the drawing in each part of the co-rotation prevention box C are aligned, the upper surface C1 is in a state of protruding to the right more than the co-rotation prevention member C2. Fig.15 As shown in , the protruding portion is equivalent to the protruding portion when the co-rotation prevention box C is installed in the screw sleeve arrangement device 200.

[0204] The protruding portion is a gripping portion CG. The gripping portion CG is provided so that an operator can grasp the gripping portion CG and disassemble the co-rotation prevention box C relative to the screw sleeve arrangement device 200. Moreover, by being larger than the co-rotation prevention component C2 and the adjustment plate C3 arranged at the lower layer of the upper surface C1, it can be formed thinner only by the thickness of the upper surface C1, so that the operator can easily hold it.

[0205] An adjustment plate C3 is provided below the co-rotation prevention member C2. As described later, when the thickness of the upper surface C1 is changed, the thickness of the adjustment plate C3 can be changed to match the change. Thus, regardless of the thickness of the upper surface C1, the overall height h of the co-rotation prevention box C can be kept constant.

[0206] When the co-rotation prevention box C is mounted on the screw sleeve arrangement device 200, as described above, the co-rotation prevention box C is inserted from the insertion port 72. Therefore, if the co-rotation prevention box C is stuck in the box receiving portion 70, the smooth removal of the co-rotation prevention box C becomes difficult.

[0207] Therefore, in the co-rotation prevention box C, an adjustment plate C3 is arranged at a position opposite to the lower surface 12 constituting the bottom surface of the box receiving portion 70. And, for example, by selecting a material that allows good sliding between the adjustment plate C3 and the lower surface 12, the co-rotation prevention box C can be smoothly installed and removed when it is installed in the box receiving portion 70.

[0208] In addition, as described later, when the height of the upper surface C1 is changed according to the type of the screw sleeve 1, the height of the adjustment plate C3 is also changed, which plays a role in making the overall height of the co-rotation prevention box C constant. Therefore, the height of the adjustment plate C3 is also selected to match the appropriate height of the upper surface C1.

[0209] However, when the height of the adjustment plate C3 needs to be very low in relation to the upper surface C1, a very thin material such as a film may be used instead of a high material such as a plate.

[0210] Furthermore, the adjustment plate C3 is provided with fixing portions C3a, C3a protruding to the side opposite to the side where the co-rotation preventing member C2 is arranged. The fixing portions C3a, C3a are fitted into the fitting portions 73, 73 formed on the lower surface 12 when the co-rotation preventing box C is mounted on the screw sleeve arrangement device 20.

[0211] Specifically, when the co-rotation prevention box C is installed in the screw sleeve arrangement device 200, the co-rotation prevention box C is inserted from the insertion port 72, for example, Fig.15 Then, when it is pushed in to a certain point, the fixing portion C3a contacts the insertion port 72.

[0212] This is because the fixing portion C3a protrudes toward the lower surface 12, but if the co-rotation prevention box C is pushed further to the left while the fixing portion C3a is in contact with the lower surface 12 of the insertion port 72, the fixing portion C3a moves upward. This is because the fixing portion C3a is urged to protrude downward from the adjustment plate C3.

[0213] Then, the co-rotation prevention box C is pushed leftward with the fixing portion C3a in contact with the lower surface 12 , and when it reaches the position of the fitting portion 73 formed on the lower surface 12 , the fixing portion C3a is moved downward by the applied force and fits into the fitting portion 73 .

[0214] Therefore, after the co-rotation prevention box C is inserted into the screw insert arranging device 200 , the fixing portions C3 a and C3 a can prevent the co-rotation prevention box C from falling off from the screw insert arranging device 200 .

[0215] On the other hand, when the co-rotation prevention box C is removed from the screw insert arranging device 200 , the co-rotation prevention box C is pulled out to the right. In this case, the fixing portion C3 a contacts the edge of the fitting portion 73 and moves upward at the adjustment plate C3 between the lower surface 12 .

[0216] That is, the co-rotation prevention box C moves rightward while the fixing portion C3a is pushed into the adjustment plate C3 while in contact with the lower surface 12. Then, when the fixing portion C3a comes out of the insertion port 72, it protrudes downward from the adjustment plate C3 again due to the applied force.

[0217] It should be noted that in the co-rotation prevention box C and the screw sleeve arrangement device 200 in the embodiment of the present invention, fixed parts C3a, C3a and interlocking parts 73, 73 are respectively provided at two places. However, the number of formations of these fixed parts and interlocking parts, the formation positions, etc. can be set arbitrarily. In addition, the formation positions, etc. can also be freely set.

[0218] Next, use the cutaway section view to re-describe the Figures 15 to 18 The screw sleeve arranging device 200 in the third embodiment has been described. Fig.19 Cut along CC line Fig.15 1 is a cut-away cross-sectional view showing a screw insert arrangement device 200 according to a third embodiment of the present invention. Fig. 20 Cut along DD line Fig.17 FIG. 2 is a cutaway cross-sectional view showing a screw insert arranging device 200 according to a third embodiment of the present invention.

[0219] Right now, Fig.19 The figure shows the state where the co-rotation preventing box C is inserted into the screw sleeve arrangement device 200. Fig. 20 The state where the co-rotation prevention box C is pulled out from the screw sleeve arranging device 200 is shown.

[0220] First, if Fig.19As shown, when the co-rotation preventing box C is inserted into the screw sleeve arrangement device 200, the gripping portion CG is in a state of protruding from the screw sleeve arrangement device 200. As described above, the gripping portion CG is a portion that the operator grasps when disassembling the co-rotation preventing box C relative to the screw sleeve arrangement device 200, and therefore protrudes in a manner that can be pulled out later even when installed in the screw sleeve arrangement device 200.

[0221] The state in which the co-rotation prevention box C is installed in the screw sleeve arrangement device 200 is similar to that used in the first embodiment. Figure 3 That is, the insert 1 mounted on the insert insertion tool 4 is accommodated in the accommodation portion C1b of the upper surface C1.

[0222] Then, the insert inserting tool 4 is lowered from the upper portion of the insert arranging device 200 and the insert I is mounted on the mandrel, and then is raised again to insert the insert I into the screw hole W1 of the workpiece W as the target.

[0223] On the other hand, the portion of the co-rotation prevention box C on the opposite side of the holding portion CG in the left-right direction contacts the insertion wall 71 of the box receiving portion 70. By pushing the co-rotation prevention box C until it contacts the insertion wall 71 and fixing it at this position, even if the co-rotation prevention box C is changed according to the type of the screw sleeve 1, the configuration position of the screw sleeve 1 can always be the set position.

[0224] It should be noted that, in this state, the fixing portion C3a provided on the adjustment plate C3 and the fitting portion 73 into which the fixing portion C3a is embedded cannot be seen. However, the fixing portion C3a is embedded into the fitting portion 73, and even if the entire screw sleeve arrangement device 200 is tilted, the corotation prevention box C will not be disengaged from the box receiving portion 70.

[0225] On the other hand, the operator can remove the co-rotation prevention box C from the screw insert arranging device 200 by gripping the grip portion CG and moving the co-rotation prevention box C to the right. Fig. 20 This status is shown.

[0226] exist Fig. 20 , the insertion wall 71 and the insertion port 72 of the box receiving portion 70 are shown. The co-rotation prevention box C can move in the left-right direction along the insertion wall 71 extending in the left-right direction. In addition, the distance (height) h from the lower end of the wall 50 to the upper end of the lower surface 12 at the box receiving portion 70 is the same as the height h of the co-rotation prevention box C.

[0227] Next, use Fig.21 The features of the co-rotation prevention box C in the third embodiment will be described.

[0228] As described above, for each screw sleeve 1 as an object to be installed on the screw sleeve insertion tool 4, there are various types of diameter and height (number of turns). In addition, when the screw sleeve is installed on the screw sleeve insertion tool 4, it is necessary to accommodate the height of the space (accommodation portion C2a) of the screw sleeve 1 as the object. Therefore, according to the type of the screw sleeve 1, the height of the upper surface C1 in the up-down direction is also different.

[0229] On the other hand, when the thickness of the upper surface C1 changes, if the thickness of other components constituting the corotation prevention box C, namely the corotation prevention component C2 and the adjustment plate C3, does not change, the height h of the corotation prevention box C will change according to the height of the upper surface C1.

[0230] When the height h of the co-rotation prevention box C changes, the box receiving portion 70 in the screw sleeve arrangement device 200 must also be adjusted in the vertical direction (refer to Fig.19 , Fig. 20 ) changes accordingly. As a result, it is also necessary to prepare the screw sleeve arrangement device 200 for the various screw sleeves 1 installed on the screw sleeve insertion tool 4, which is uneconomical.

[0231] Therefore, in the co-rotation prevention box C in the third embodiment of the present invention, it is configured that even if the height of the upper surface C1 changes according to the height of the screw sleeve I, the height h of the entire co-rotation prevention box C will not change.

[0232] That is, since the height of the upper surface C1 may vary depending on the type of the screw sleeve 1, the height of the adjustment plate C3 is changed in accordance with the height of the upper surface C1. More specifically, if the height of the upper surface C1 becomes higher, the height of the adjustment plate C3 is lowered. Conversely, if the height of the upper surface C1 is lowered, the height of the adjustment plate C3 is increased. Fig.21 This explains the above point.

[0233] Fig.21 The following is a cross-sectional view showing a co-rotation prevention box C according to a third embodiment of the present invention, wherein (A) is a cross-sectional view showing the co-rotation prevention box C described above. Fig.21 (B) is a cut-away cross-sectional view showing the co-rotation prevention box C in a state where the thickness of the upper surface C1 and the adjustment plate C3 are changed.

[0234] Fig.21 The co-rotation prevention box C shown in (A) is, for example, Fig.18 The same as the co-rotation prevention box C shown in the cut-away cross-sectional view of (B). Fig.18 The co-rotation prevention box C shown in (B) is still Fig.21 In the co-rotation prevention box C shown in (A), the height h1 of the upper surface C1 constituting the co-rotation prevention box C, the height h2 of the co-rotation prevention member C2, and the height h3 of the adjustment plate C3 are all the same.

[0235] For the sake of convenience, the Fig.21 The height of each part of the co-rotation prevention box C shown in (A) is used as a reference for explanation. Fig.21 The co-rotation prevention box C' shown in (B) is, at first glance, known to be of the same height as the upper surface and the adjustment plate. Fig.21 The co-transfection prevention box C of (A) is different.

[0236] That is, here, Fig.21 The height of the upper surface C1' in the co-rotation prevention box C' shown in (B) is set to a height h1', the height of the co-rotation prevention member C2' is set to a height h2', and the height of the adjustment plate C3' is set to a height h3'.

[0237] First, the height h1 of the upper surface C1 is lower than the height h1 ′ of the upper surface C1 ′. That is, the thickness of the upper surface C1 in the co-rotation prevention box C is thinner than the thickness of the upper surface C1 ′ of the co-rotation prevention box C′.

[0238] In contrast, the height h3 of the adjustment plate C3 is higher than the height h3' of the adjustment plate C3'. That is, the thickness of the adjustment plate C3 in the co-rotation prevention box C is greater than the thickness of the adjustment plate C3' in the co-rotation prevention box C'.

[0239] On the other hand, the heights of the co-rotation prevention box C and the co-rotation prevention box C' as a whole are the same height h. That is, even if the heights of the upper surface and the adjustment plate change, the height of the co-rotation prevention box as a whole can be maintained.

[0240] In this way, even if the upper surface C1 is changed according to the type of the screw sleeve 1 installed, the height h of the co-rotation prevention box C is kept constant by adjusting the height of the adjustment plate C3. In this way, no matter which screw sleeve 1 is used, although the co-rotation prevention box C may be different, one screw sleeve arrangement device 200 can be utilized.

[0241] [action]

[0242] Next, the process of the screw inserting method using the screw inserting system S in the third embodiment of the present invention is described. However, the basic process is as previously used. Figure 7 Different from the previous process, there is an operation of preventing the co-rotation box C from being installed on the screw sleeve arrangement device 200 before the initial step. Here, the following is an example of the operator preventing the co-rotation box C from being installed on the screw sleeve arrangement device 200 by manual operation.

[0243] As mentioned above, corotation prevents box C from being provided with according to the screw sleeve 1 of the object that is installed on screw sleeve inserting tool 4. Therefore, the operator selects the corotation preventing box C that matches with the screw sleeve 1 as the installation object. Then, selected corotation prevents box C from being embedded in screw sleeve arranging device 200.

[0244] Specifically, when the co-rotation prevention box C is inserted into the screw sleeve arrangement device 200, the operator grasps the gripping portion CG and causes the co-rotation prevention box C, on the opposite side to the gripping portion CG, to enter the box receiving portion 70 from the insertion port 72. Then, the co-rotation prevention box C is moved toward the insertion wall 71 disposed at a position opposite to the insertion port 72.

[0245] When the co-rotation prevention cartridge C is moved in the cartridge receiving portion 70, for example, Fig.17 When the co-rotation prevention box C is pushed into the screw sleeve arrangement device 200 until it contacts the insertion wall 71 disposed at a position opposite to the insertion port 72, the co-rotation prevention box C cannot be moved any further.

[0246] At the same time, the fixing portion C3a of the adjustment plate C3 provided on the co-rotation prevention box C is embedded in the fitting portion 73 of the lower surface 12. Thus, the co-rotation prevention box C will not fall off from the screw sleeve arranging device 200 until the operator grasps the grip portion CG and pulls it out.

[0247] Then, after the co-rotation preventing box C is installed on the screw sleeve arrangement device 200, according to the use Figure 7 The described flow executes the processing of the insert insertion method using the insert insertion system S.

[0248] By adopting the above-described screw sleeve arrangement device 200 or the screw sleeve insertion method using the screw sleeve arrangement device 200, the screw sleeve can be reliably installed on the screw sleeve insertion tool while eliminating the danger of installing the screw sleeve on the screw sleeve insertion tool, while preventing the screw sleeve from rotating together during installation. In addition, the number management and insertion management of the screw sleeves when inserting a large number of screw sleeves into the workpiece can be easily performed.

[0249] Particularly, the mechanism of screw sleeve corotation during preventing installation is integrated into corotation prevention box C according to the kind of screw sleeve 1 to be installed. Therefore, as long as selecting the corotation prevention box C that matches with screw sleeve 1, just can easily prevent the corotation that matches with the kind of screw sleeve 1.

[0250] In addition, a co-rotation preventing box C in which at least the upper surface C1 and the co-rotation preventing component C2 are integrated is assembled on the screw sleeve arrangement device 200 in the third embodiment. And, about the functions of these upper surface C1 and the co-rotation preventing component C2, as described in the screw sleeve arrangement devices 1 and 100 in the first and second embodiments, their functions are no different. Therefore, even if the co-rotation preventing box C is assembled on the screw sleeve arrangement device 200, the above-mentioned effect can be achieved.

[0251] It should be noted that the present invention is not limited to the above-mentioned embodiment as it is, but is just an example of the present invention. In the implementation stage, the constituent elements can be deformed to be specific within the scope of the main purpose, and various changes or improvements can be made to the above-mentioned embodiment. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-mentioned embodiment.

[0252] For example, several components may be deleted from all components shown in the embodiment. Furthermore, components in different embodiments may be appropriately combined, and such changes or improvements may also be included in the present invention. This embodiment and its variations are included in the scope and gist of the invention, and are included in the invention described in the claims and their equivalents.

[0253] In the above description, the screw sleeve arranging device 1 is constructed on the premise that the operator moves the gripping portion 60 when the arranging portion 10 is tilted. However, for example, a tilting mechanism using some kind of power may be provided to tilt the arranging portion 10 using the tilting mechanism.

[0254] Similarly, regarding the method of sliding the wall 101 , in addition to the above-mentioned method in which the operator moves the wall 101 via the gripping portion 60 , a method of sliding the wall 101 using some kind of power may be adopted.

[0255] In addition, as described above, the actions of the devices constituting each part of the screw inserting system S can be automated. The same is true when the co-rotation preventing box C in the third embodiment is used. For example, the co-rotation preventing box C can be selected according to the type of the screw insert I to automate its assembly and disassembly relative to the screw insert arranging device 200.

[0256] In addition, in the first embodiment, the opening portion O is formed by opening the opening wall 51 as a part of the wall 50 by tilting the arrangement portion 10, so that the remaining screw inserts 1 are discharged from the screw insert arrangement device 1. The opening wall 51 is fixed to the upper part of the wall 50 and the hinge 40, while the lower part thereof is not fixed, so the opening portion O is formed by the above-mentioned action, but the method for forming the opening portion O is not limited to such a method. For example, the opening portion O can also be formed by sliding a part of the wall 50 or removing a part thereof.

[0257] In addition, also with regard to the inclination of the arrangement portion 10 in the screw sleeve arrangement device 1, for example, as previously used Figure 6 As described above, the opening wall 51 as one side of the wall 50 is tilted so that the entirety is located at the bottom. However, for example, the arrangement portion 10 may be tilted so that the corner formed by the wall 50 is located at the bottom, so that the opening O is formed at the corner.

[0258] Alternatively, for example, a pair of walls 50 facing each other in the wall 50 may be formed as opening walls 51, and the arrangement portion 10 may be tilted so that each opening wall 51 is located at the lower side. In this way, by tilting the arrangement portion 10 like a seesaw, the remaining screw sleeves 1 can be discharged more quickly.

[0259] It should be noted that, in the co-rotation prevention box C of the third embodiment, as described above, the change in the height of the upper surface C1 is adjusted only by the adjustment plate C3. Therefore, the co-rotation prevention member C2 sandwiched between the upper surface C1 and the adjustment plate C3 does not contribute to the adjustment of the height change. However, the overall height of the co-rotation prevention box C can be maintained by adjusting the height of the co-rotation prevention member C2 for the change in the height of the upper surface C1.

[0260] In addition, it has been described above that the arrangement portion 10 can be changed according to the type of the screw sleeve 1 installed on the screw sleeve insertion tool 4 in the first and second embodiments, and on the other hand, in the third embodiment, the co-rotation prevention box C can be changed according to the type of the screw sleeve 1 installed on the screw sleeve insertion tool 4. This is because the diameter size and the number of turns are different according to the type of the screw sleeve 1.

[0261] Therefore, the diameter size is dealt with by changing the diameter of the housing portion 111b, C1b. On the other hand, when the diameter is the same but the number of turns is different, the height of the housing portion 111b, C1b is changed. Moreover, by changing the height of the housing portion 111b, C1b, the thickness (height) of the upper surface 11, C1 is also different.

[0262] However, for example, when only the number of turns is different but the diameter is the same, the height of the receiving portion 111b, C1b may not be changed. For example, the height of the receiving portion 111b, C1b may be changed by adjusting the angle of the tapered portion 111a, C1a. If this is the case, it is conceivable that the thickness (height) of the upper surface 11, C1 may not be changed even if the height of the receiving portion 111b, C1b is changed.

[0263] Furthermore, it can be imagined that when the screw sleeve 1 is stored in the storage part 111b, C1b and arranged, it is not necessary to store the screw sleeve 1 in its entirety in the storage part 111b, C1b, and it is sufficient even if the other end of the screw sleeve 1 protrudes from the area of ​​the tapered part 111a, C1a. In this case, by adjusting the angle of the tapered part 111a, C1a and the height of the storage part 111b, C1b, a plurality of screw sleeves 1 having the same diameter but different numbers of turns can be handled with one upper surface 11, C1.

[0264] Therefore, it is necessary to prepare an arrangement part 10 and a co-rotation prevention box C corresponding to the type of the screw sleeve I. On the other hand, for screw sleeves I with the same diameter but the only difference in the number of turns, it is possible to use the arrangement part 10 and the co-rotation prevention box C in common to a certain extent.

[0265] In the third embodiment, the co-rotation prevention box C is fixed by fitting the fixing portion C3a into the fitting portion 73 of the lower surface 12 as an example of a fixing method when the co-rotation prevention box C is mounted on the screw insert arranging device 200. However, the fixing method is not limited to this method.

[0266] For example, a movement preventing member may be provided at a portion of the lower surface 12 directly below the insertion port 72. The movement preventing member is, for example, in the shape of a long plate, and a portion in the longitudinal direction is rotatably fixed to the lower surface 12.

[0267] In addition, the length in the long side direction is as follows: that is, when it is rotated to be parallel to the up and down direction of the screw sleeve arrangement device 200, the length does not exceed the height of the adjustment plate C3 of the co-rotation prevention box C installed on the screw sleeve arrangement device 200 and the co-rotation prevention component C2 in the up and down direction.

[0268] The movement preventing member is arranged in such a direction that its long side direction is the front-back direction when the co-rotation preventing box C is not mounted on the screw insert arranging device 200. Since it is arranged in such a direction, the movement preventing member does not block the insertion port 72.

[0269] On the other hand, after the corotation preventing box C is installed on the screw sleeve arrangement device 200, the movement preventing component is rotated so that its long side direction is the up-down direction. Under this state, even if you want to pull out the corotation preventing box C from the screw sleeve arrangement device 200, the movement preventing component can also contact with the part of the adjustment plate C3 and the corotation preventing component C2 and suppress the corotation preventing box C from moving in the left-right direction.

[0270] Furthermore, as described above, the length of the anti-movement member in the longitudinal direction is such that even if the anti-movement member is rotated to be parallel to the vertical direction, it will not exceed the height of the adjustment plate C3 and the anti-corotation member C2 in the vertical direction.

[0271] In this way, various structures and mechanisms can be adopted for the fixing portion for preventing the co-rotation prevention box C installed in the screw sleeve arranging device 200 from falling off.
