[Technical Field]

[0001] The present invention relates to a locking piece attaching device that can be used to bind appropriate goods such as clothing, small items such as socks, or shoes, bags, and attach locking pieces such as tags, indicators, etc., such as brand labels, price tags, material descriptions, and usage instructions to the goods. More specifically, the present invention relates to a locking piece attaching device used to attach locking pieces that display appropriate tags, price tags, registered trademarks, quality labels, manufacturer names, distributor names, etc., to appropriate goods, and to a loop pin used in the locking piece attaching device. [Background technology]

[0002] BACKGROUND ART In general, various types of fastening piece attaching devices have been used in the past to fasten clothing items, everyday accessories, sandals, shoes, etc., and to efficiently attach fastening pieces such as brand labels and price tags to the products. For example, conventional locking piece attaching devices have been used in which, by gripping a lever formed on a pistol-shaped main body device, a loop is formed by sequentially ejecting each loop pin from a loop pin assembly, which is made up of a plurality of loop pins arranged in parallel with each other and each of the insertion heads and sockets temporarily fastened together to an appropriate connecting bar, with an appropriate tag, label, etc. interposed therebetween, and inserting the insertion head into the socket to form a loop.

[0003] On the other hand, the inventor of the present application has conducted extensive and intensive research together with the engineers of MIT International Limited, an affiliated company of the inventor of the present application, and independently came up with a solution as shown in Japanese Patent Laid-Open No. 2000-238714 (Patent Document 1), Japanese Patent Laid-Open No. 2000-289727 (Patent Document 2), Japanese Patent Laid-Open No. 2001-354218 (Patent Document 3), Japanese Patent Laid-Open No. 2001-56644 (Patent Document 4), Japanese Patent Laid-Open No. 2004-83133 (Patent Document 5), etc., and as is clear from the schematic perspective views of FIG. 10 or FIG. 11 of the present application, a grip lever 12 rotatably supported on a device body grip portion 11 provided on the device body portion 10; a drive arm 13 rotated by the grip lever 12; a first guide passage 42 arranged in the device body portion 100 and extending from a vicinity of a rear end portion 40 of the device body portion 10 to a front end portion 41 of the device body portion 10 along the longitudinal direction of the device body portion 10; The first guide passage 42 is provided with a first drive pin 16 that moves linearly back and forth in response to the swinging motion of the drive arm 13, and the second guide passage 43 is provided with a second drive pin 19 made of a flexible member that moves back and forth in response to the swinging motion of the drive arm 13. The first drive pin 16 has a predetermined length and is provided with an insertion head 3 that has an appropriate engagement portion 6 at one end of a flexible yarn body 2 that is supplied separately, and the insertion head 3 has a predetermined length and is provided with an appropriate engagement portion 6 at one end of the yarn body 2. The other end of the body 2 is provided with a socket 5 having a hole 4 with a locking portion 6 for irreversibly inserting and fitting the insertion head 3 of each loop pin 1, and the second ejection pin 19 is configured to abut against the insertion head 3 loaded and supplied into the first guide passage 42, and to eject the insertion head 3 linearly to the front outside of the device main body 10 through a desired hollow guide member 50 in response to operation of the grip lever 12, while the second ejection pin 19 abuts against the socket 5 separately loaded and supplied into the second guide passage 43,The second ejection pin 19 is connected to the open end 41 of the device body 100, and the tip of the curved hollow guide member 20 is fixedly installed so as to be positioned on the ejection direction line of the insertion head 3. In response to the operation of the grip lever 12, the socket portion 5 is slidably moved to the fitting position 54 with the insertion head 3, and the insertion head 3 and the socket portion 5 are fitted together at that position 54. This locking piece attaching device 100 has been developed and is available on the market.

[0004] In the specific example of Figure 10, the first guide passage 42 and the second guide passage 43, which will be described later, are arranged and formed on approximately the same horizontal plane, but as shown in Figure 11, the locking piece mounting device may have a configuration in which the first guide passage 42 and the second guide passage 43 are arranged and formed on different horizontal planes. Furthermore, in the above-mentioned locking piece mounting device 100, a gap portion 70 having an appropriate distance and depth is formed between the wall surface including the first guide passage 42 and the wall surface including the second guide passage 43, and the bottom surface of the gap portion 70 is formed in a closed shape by a horizontal bottom surface portion 102 or an inclined bottom surface portion 101. It goes without saying that the guide passages 42, 43 defined in the above-mentioned conventional example may be virtually set within the space. Here, the basic structure and operation of the above-mentioned conventional locking piece attaching device, which is the subject of the present invention, will be outlined with reference mainly to the locking piece attaching device 100 shown in FIG. The configuration of the locking piece attachment device 100 disclosed in Figure 10 is substantially the same as that of Figure 11, except that the first guide passage 42 and the second guide passage 43 are arranged on the same horizontal plane.

[0005] 11 to 15, a specific example of the configuration of each component of the mechanism of the locking piece attaching device 100 shown in FIG. 11 includes a grip lever 12 pivotally supported on a device body grip part 11 provided on a pistol-shaped device body 10, a drive arm 13 pivoted by the grip lever 12, a first guide passage 42 disposed within the device body 10 and extending from the vicinity of a rear end 40 of the device body 10 to a front end 41 of the device body 10 along the longitudinal direction of the device body 10, and a predetermined guide passage 42 and a predetermined guide passage 43. A second guide passage 43 is provided, which is disposed approximately parallel to the first guide passage 42 with a gap therebetween and extends from the vicinity of the rear end 40 of the device body 10 to the front end 41 of the device body 10, and a first ejection pin 16 which moves linearly back and forth in response to the swinging action of the drive arm 13 is provided within the first guide passage 42, and a second ejection pin 19 which is made of a flexible member and moves back and forth in response to the swinging action of the drive arm 13 is provided within the second guide passage 43, and the first ejection pin 16 is provided within the first guide passage 42. In the passage 42, an insertion head 3 having an appropriate engaging portion 6 is provided at one end 60 of a flexible thread body 2 having a predetermined length, and a socket portion 5 having a hole 4 with a locking portion 116 for irreversibly inserting and fitting the insertion head 3 is provided at the other end 30 of the thread body 2. The individual loop pins 1 come into contact with the insertion head 3 loaded and supplied into the first guide passage 42, and in response to the operation of the grip lever 12, the insertion head 3 is linearly discharged out of the device main body 10 through a desired hollow guide member 50. On the other hand, the second ejection pin 19 abuts against the socket portion 5 of the loop pin 1 separately loaded and supplied into the second guide passage 43, and is connected to the front open end 41 of the device main body 10 of the second guide passage 43, and slides the socket portion 5 to a fitting position 54 with the insertion head 3 in response to operation of the grip lever 12 within a curved hollow guide member 20 which is fixed and installed in a state inclined obliquely downward so that a tip portion 51 of the second ejection pin 19 is positioned on the ejection direction line of the insertion head 3, andThe insertion head 3 and the socket 5 are configured to fit together.

[0006] Furthermore, in the conventional locking piece mounting device 100, a gap 70 having an appropriate distance and depth is formed between the wall surface including the first guide passage 42 and the wall surface including the second guide passage 43, and the bottom surface of the gap 70 is formed in a closed shape by a horizontal bottom surface portion 102 or an inclined bottom surface portion 101. As mentioned above, the conventional locking piece attachment device 100 is configured so that the plane formed by the first guide passage 42 incorporating the first ejection pin portion 16 and the plane formed by the second guide passage 43 incorporating the second ejection pin portion 19 are different, as shown in Figure 11. Specifically, the plane including the first guide passage 42 is positioned lower than the plane including the second guide passage 43, and an inclined bottom surface portion 101 exists in the recess between them. In the specific example shown in Figure 10, as is clear from the plan view and front view in Figures 16 and 17, the plane formed by the first guide passage 42 and the plane formed by the second guide passage 43 are formed to be the same plane, and a horizontal bottom surface portion 102 exists in the recess between them.

[0007] An example of a more specific configuration of the drive mechanism of the above-mentioned conventional locking piece attaching device 100 and its drive system will be described in detail below with reference to the drawings. 12(A), 12(B), 13, 14(A) and 14(B) are side views and plan views showing an example of the internal structure of the locking piece attaching device 100. FIG. Here, the conventional device main body 10 comprises a grip lever 12 pivotally supported on a device main body grip part 11, a drive arm 13 rotated by the grip lever 12, a first pin holder part 15 linearly sliding on a first guide rail 14 by the drive arm 13, a first ejection pin 16 attached to the first pin holder part 15 and sliding back and forth within the first guide passage 42, a second pin holder part 18 linearly moving on a second guide rail 17 by the drive arm 13, and a flexible member such as a tightly wound coil spring having a base end fixed to the second pin holder part 18. and a second ejection pin 19 that slides back and forth within the second guide passage 43, and the second ejection pin 19 is connected to the outlet of the second guide passage 43 at the tip portion 41 of the device main body 10 and is provided with a curved hollow guide member 20 that guides the second ejection pin 19, and the guide member 20 is curved and changes its height and horizontal position so that its tip portion 51 is positioned lowered to the sliding protruding position of the first ejection pin 16, and the second ejection pin 19 is configured to be able to reach the tip portion 51.

[0008] On the other hand, the grip lever 12 is rotatably supported on a pin 21 erected on the device main body 10 as shown in Figures 12(A), 12(B) and 13, and has a first cam 22 formed on its inner surface that abuts against the base end portion of the drive arm 13. By appropriately changing the shape of this cam, the moving speed of the first ejection pin 16 can be changed. The first cam 22 is formed in a shape that allows it to always abut against the roller 24 at a right angle even when the grip lever 12 rotates around the pin 21 . On the other hand, the drive arm 13 is rotatably supported by a support shaft 23 erected on the inner surface of the grip portion 11 at approximately the center, and a base end portion 13a thereof is bent at a right angle. A roller 24 is rotatably attached to the base end portion 13a. Furthermore, a spring member 25, one end of which is fixed to the grip portion, is attached to a portion 13b of the drive arm 13. The drive arm 13 is urged to rotate clockwise by this spring member 25. Therefore, the roller 24 at the base end is always urged in a direction that brings it into perpendicular contact with the first cam 22.

[0009] 18(A), 18(B) and 19, the drive arm 13 is provided with a second cam 26 that drives the first pin holder part 15. The second cam 26 has curved parts 26a and 26b that are curved almost symmetrically on both sides, and has a pointed head 26c at the upper end. A hole 13c is formed at the tip of the drive arm 13, and a link member 27 that is connected to the second pin holder portion 18 is rotatably connected thereto. The link member 27 is connected to the tip of the drive arm 13 via an elongated hole.

[0010] 18(A) and 18(B) are explanatory diagrams showing the relationship between the first pin holder portion 15 and the second cam 26. FIG. 18(A) shows a state in which the drive arm 13 is urged to rotate clockwise by the spring member 25 without the grip lever 12 being gripped (see FIG. 12(A)). The first pin holder portion 15 has been moved to the right in the figure by the curved portion 26b of the second cam 26, and the first ejection pin 16 has also retracted to the innermost position. The second cam 26 is inserted into the central groove of the first pin holder portion 15.

[0011] FIG. 18(B) shows a state in which the grip lever 12 is gripped and the drive arm 13 is rotated counterclockwise against the spring member 25 (see FIG. 12(B)). The first pin holder part 15 has been moved to the left in the figure by the pointed part 26c of the second cam 26, and the first ejection pin 16 has also protruded to its farthest end. The relationship between the first pin holder part 15 and the second cam 26 is such that initially the curved part 26a abuts against the side wall of the groove of the first pin holder part 15, but as the drive arm 13 rotates gradually, the notched part 26 of the second cam abuts, and the feed speed of the first pin holder part 15 temporarily decreases near the end. Furthermore, in the final stage, the pointed part 26c falls into the small recess 15a formed in the side wall of the groove, and the first pin holder part 15 can be held in this state.

[0012] The second pin holder portion 18 is connected to the drive arm 13 via a link member 27, and moves linearly while being guided by the second guide rail 17 (see FIG. 13). When the drive arm 13 rotates counterclockwise, the link member 27, which had been pressing the second pin holder portion 18 in an inverted L-shape, rotates in a toggle-like manner at the long hole portion, changing the movement speed of the second pin holder portion 18 near the end. In other words, when the link member 27 rotates in a toggle manner, the second pin holder portion 18 hardly moves. This mechanism can prevent the second ejection pin 19 from bouncing back. Therefore, the socket portion can be held and fixed to the tip 51 of the guide member 20. In addition, the socket part 5 that has reached the tip 51 of the guide member 20 first can be placed on standby.

[0013] Next, a specific example of the procedure for using the locking piece attaching device 100 configured as above will be described. First, the loop pin 1 is attached to the attachment portion from the top surface of the main device portion 10. As shown in Figure 15, the loop pin 1 has a socket portion 5 that is high and an insertion head portion 3 that is low. This inclination is the same as the inclination of the guide member 20. When the grip lever 12 is gripped, it rotates around the pin 21, and the drive arm 13, which is in contact with the grip lever 12 via a roller 24, rotates counterclockwise against the spring member 25. When the drive arm 13 rotates, the first pin holder part 15 engaged with the second cam 26 moves forward along the first guide rail 14. When the first pin holder part 15 moves forward, the first ejection pin 16 fixed thereto ejects one of the insertion head parts 3 forward.

[0014] On the other hand, when the drive arm 13 rotates, the link member 27 connected to the tip of the drive arm 13 rotates, causing the second pin holder portion 18 to advance along the second guide rail 17 . The second pin holder part 18 is located farther from the rotation center of the drive arm 13, and therefore moves forward at a faster speed than the first pin holder part 15. Also, the distance that the socket part 5 travels through the guide member 20 to reach its tip position 51 is longer than the distance that the insertion head part 3 travels in a straight line, so the stroke for movement is also set long. The movement timing of the two parts is set so that the socket part 5 reaches the tip position 51 first, and then the insertion head part 3 reaches the tip position 51 and couples with each other at part 54.

[0015] Furthermore, the forward movement speed of the first ejection pin 16 is temporarily reduced near the protruding end due to the structure of the second cam 26 and the first pin holder portion 15, and the first ejection pin 16 is latched at the protruding end, preventing cracks from occurring in the loop pin. Furthermore, since the first ejection pin 16 is latched in the protruding state, the insertion head portion can be securely attached to the socket portion. The second pin holder portion 18 is connected to the tip of the drive arm 13 via a link member 27, so that it rotates in a toggle manner at the hole 13c, changing the moving speed of the second pin holder portion 18 near the end portion. In other words, when the link member 27 rotates around the hole 13c, the second pin holder portion 18 hardly moves forward. This mechanism prevents the second ejection pin 19 from bouncing back, and enables the socket portion 28a to be held and fixed to the tip of the guide member 20.

[0016] Next, an example of a method of using the conventional locking piece attaching device 100 will be specifically described. First, an example of the configuration of the loop pin 1 used in the conventional locking piece attaching device 100 will be described with reference to FIG. In other words, each loop pin 1 used in the conventional locking piece attaching device 100 is a single sealing device 1, as shown in Figures 20(A) to 20(D), consisting of a flexible filament-like body portion 2, an insertion head portion 3 having an appropriate engaging portion 6 provided at one end 60 of the filament-like body portion 2, and a socket portion 5 having a hole 4 formed therein with an engaging portion 116 for irreversibly passing the insertion head portion 3 provided at the other end 30 of the filament-like body portion 2, and is configured so that by inserting the insertion head portion 3 through the opening 4 provided in the socket portion 5, the engaging portion 6 provided on the insertion head portion 3 engages with a stopper portion consisting of a blade-shaped engaging portion 116 arranged within the opening 4 of the socket portion 5, making it impossible for the insertion head portion 3 to come off from the opening 4 of the socket portion 5.

[0017] Furthermore, in this conventional example, the loop pin 1 is attached to a specific product while holding an appropriate tag, but this operation is performed mechanically, and in order to perform this operation efficiently, it is desirable to arrange multiple loop pins 1 in parallel to each other, as shown in Figure 20(A), and fix a portion of the insertion head 3 of each loop pin 1 to a predetermined connection bar 8 in a state where it can be easily cut off, and fix a portion of the socket portion 5 of each loop pin 1 to a separate predetermined connection bar 8' in a state where it can be easily cut off, thereby forming and using an integrated sheet-like loop pin assembly 9.

[0018] Next, in order to mount the above-mentioned loop pin assembly 9 on the locking piece attaching device 100 and actually eject the individual loop pins 1, as shown in Figures 10, 11, 14(B) and 16, the two connection bars 8, 8' of the loop pin assembly 9 are brought close to each other and the filament portion 2 is bent into a U-shape, and in this state, the connection bar 8 of the two connection bars 8, 8' is inserted into the vertical groove 32 for inserting the connection bar 8 provided in the locking piece attaching device 100, and the insertion head 3 is inserted into the first guide passage 42 that guides the first ejection pin 16, and at the same time, the connection bar 8' is inserted into the vertical groove 33 for inserting the connection bar 8' provided in the locking piece attaching device 100, and the loop pin assembly 9 is set on the locking piece attaching device 100 so that the socket portion 5 is inserted into the second guide passage 43 that guides the second ejection pin 19. Thereafter, the above-mentioned mechanism is activated each time the grip lever 12 of the locking piece attachment device 100 is pulled, and at the same time, an appropriate loop pin feeding mechanism (not shown) is also activated to sequentially feed the individual insertion heads 3 and sockets 5 of the loop pin 1 into the first and second guide passages one by one, thereby striking each component individually to form a loop.

[0019] However, in the above-mentioned conventional latch piece attaching device 100, as shown in Figure 10 or Figure 11, the loop pin sheet 9 is mounted in a curved state on the latch piece attaching device 100, and the loop pins 1 are continuously punched out one by one to attach them to specific products so as to form closed loops together with tags, labels, price tags, etc., but in the central part of the thread body portion 2 of each loop pin 1, the part where the thread body portion 2 is greatly curved has no connection or fixation whatsoever between the thread body portions of other loop pins 1 arranged adjacent to each other, so that the central part of each thread body portion 2 is in a free state, that is, it is in a state where it can be displaced and deformed freely.

[0020] Therefore, in such a state, if any tension fluctuation or any abnormal force is applied to any part of each thread-shaped body portion 2, the thread body portion 2, including the central curved portion which is in the freely moving state, will easily be displaced, deformed or misaligned in a variety of directions, resulting in the thread body portion 2 coming into contact with or becoming entangled with the curved thread body portion 2 of another adjacent loop pin 1. As a result, if the thread body portions 2 of adjacent loop pins 1 become entangled or come into contact and fixed, the loop pin 1 that has been shot out will not be completely engaged with the socket portion 5 and the insertion portion 3, and if the next loop pin 1 is shot out without knowing that the loop pin 1 has not been fully connected, a jam will occur inside the hollow guide 50 or the curved guide portion 20, making it much time-consuming to remove the loop pin, which will significantly reduce work efficiency.It will also cause a malfunction of the locking piece attaching device 100, making it unusable. Furthermore, even if the insertion head 3 and the socket portion are completely engaged, if the curved thread body portion 2 is entangled and intertwined with each other as described above, there have been many cases where the loop pin 1 including a tag or the like cannot be separated and removed from the locking piece attaching device 100.

[0021] In order to solve these problems, the inventors of the present application and other related parties have examined the causes of the above-mentioned problems and proposed specific improvement measures for solving each of the individual causes, as shown in Japanese Patent Application Laid-Open No. 2000-238714 (Patent Document 1), Japanese Patent Application Laid-Open No. 2000-289727 (Patent Document 2), Japanese Patent Application Laid-Open No. 2001-056644 (Patent Document 4), Japanese Patent Application Laid-Open No. 2005-207171 (Patent Document 6), and Japanese Patent Application Laid-Open No. 2010-126176 (Patent Document 7), etc. However, it is still not possible to achieve a sufficient and complete effect of preventing the occurrence of entanglement itself, and in particular when the thread portion 2 of the loop pin 1 is a thin filament, or when a more flexible thread-like material such as thread, twisted yarn, braided cord, or knitted cord is used, or when the firing speed of the loop pin 1 is increased, the probability of entanglement occurring increases, and the current situation is that it is quite difficult to eliminate this drawback. In other words, in the method of using the above-mentioned conventional loop pins with the above-mentioned conventional loop pin fastening device to fasten the conventional loop pins and attach appropriate tags or the like to appropriate merchandise, for reasons as shown in the several known examples above, the filament portions constituting each loop pin used may become entangled with the filament portions constituting adjacent loop pins, or may cross-engage with each other, or may come into contact with each other and become inseparable, resulting in the individual insertion portions and individual socket portions of the loop pin being unable to fit together, or even if both are fitted together, because the filaments constituting each loop pin are entangled, it is often difficult to remove the loop pin from the loop pin fastening device even after the loop pin hammering operation is completed, and the removal operation requires a considerable amount of time and effort, which significantly reduces the efficiency of the tag attachment operation and is a factor in increasing costs.

[0022] Therefore, the inventors of the present application continued their intensive research and further investigated other causes of the thread portions 2 of the loop pins 1 becoming entangled and intertwined with each other, resulting in an incomplete punching operation or making it difficult to remove the defective punched loop pin from the main device. As a result, it was discovered that the new cause was that after the insertion portion 3 is punched out of the machine by the first punch pin 16, when the first punch pin retracts to its original position, while the filament portion (thread portion) 2 of the loop pin 1 that was just punched out has not yet been removed, the insertion portion 3' of the subsequent loop pin 1' above it for some reason descends and comes into contact with the filament portion 2 of the previous loop pin 1 that is still remaining in the first guide passage 42. This makes it impossible to remove the previous punched loop pin 1 from the loop pin joining device 10, and at the same time makes it impossible to punch out the next loop pin. Specifically, as shown in Figure 21, after the first ejection pin 16 has ejected the insertion head 3 from the hollow guide member 50 within the first guide passage 42, when the first ejection pin 16 returns to its original position, the insertion portion 3' constituting the next loop pin 1 descends from above into the insertion head fitting opening 53 provided in the first guide passage 42, and the thread body portion 2 (shown in black) of the previous loop pin that was ejected earlier comes into contact with and becomes entangled with the previous loop pin within the first guide passage 42, making it impossible to eject the previous loop pin completely from the main device 10, and making it impossible to remove the entangled loop pins from the main device 10, or making it impossible to eject the next loop pin. This is a new cause of the problem. It goes without saying that the same problem occurs at the socket fitting opening in the second guide passage 43 of the locking piece attaching device 100.

[0023] Furthermore, as another cause, in the past, when the above situation occurred, the loop pin 1 whose insertion portion 3 could not be mated with the socket portion 5, or the loop pin 1 whose insertion portion 3 could be mated with the socket portion 5 but whose adjacent loop pins 1 had their filament portions 2 crossed and intertwined and joined as described above, had to be manually removed in the main unit 10 of the loop pin connecting device along the extrusion direction of the first ejection pin 16. However, because the curved socket portion feed guide portion 20 is located in front of the main unit 10, there was little working space, making it a time-consuming task requiring great care and delicate movements, and it was also found to be the cause of a significant decrease in working efficiency.

[0024] Furthermore, the inventor further investigated the cause of the filament portions 2 of adjacent loop pins 1 becoming entangled and interlocked with each other, and found that in the conventional loop pin launching device 100, the bottom surfaces 101, 102 of the gap 70 between the first guide passage 42 that launches the insertion portion 3 and the second guide passage 43 that launches the socket portion 5 are closed, so the filament portions 2 that make up each of the multiple loop pins 1 come into contact with the flat or inclined surfaces of the bottom surfaces 101, 102, and are subjected to a reaction force that pushes them upward.This, combined with external forces caused by the loop pin launching device frequently moving up and down and left and right within the space, causes the adjacent filament portions 2 to be affected by vibrations, etc., and easily become entangled with each other. It has been found that this phenomenon occurs with an extremely high probability when the filament portion is thin and highly flexible, or when a thread-like material such as twisted yarn is used for the filament portion, as it is deformed and meandered more than expected at the lower surface bottom portions 101 and 102. On the other hand, it was also found that when the filament portion is thin and flexible or when the filament portion uses the thread-like material, after the firing operation, when the filament portion of the previous loop pin is pulled forward toward the part where the insertion portion and the socket portion fit together, the filament portion of the next loop pin is dragged forward by the pulling-out action of the filament portion of the previous loop pin, which is one of the causes of adjacent filaments becoming further entangled. As a result of further intensive research, the inventors of the present application have discovered and put into practical use a technology that solves the problems of the prior art described above and allows for efficiently, quickly, and more accurately attaching and fastening the desired fastening piece to the desired product.

[0026] Therefore, the object of the present invention is to solve the above-mentioned problems of the conventional technology, to provide a locking piece attaching device which effectively prevents the filament portions 2 of adjacent loop pins from becoming entangled, and which allows the loop pins to be used to attach labels, tags, price tags, etc. easily, quickly, and with high work efficiency, and to provide a locking piece attaching device which allows the loop pins to be easily removed from the locking piece attaching device even when entanglement occurs as in the conventional case, causing the loop pins to come into contact and be fixed, and when this causes the insertion head and socket portion of the loop pin to end in an incomplete engagement, making it difficult to remove the loop pin from the locking piece attaching device, and further to provide a preferred loop pin to be used in the locking piece attaching device in order to achieve the above-mentioned object.

[0027] That is, the locking piece attaching device according to the first aspect of the present invention comprises a grip lever rotatably supported on a device body grip portion provided on a device body, a drive arm rotated by the grip lever, a first guide passage disposed within the device body and extending from the vicinity of the rear end of the device body to the front end of the device body along the longitudinal direction of the device body, and a second guide passage disposed substantially parallel to the first guide passage at a predetermined interval and extending from the vicinity of the rear end of the device body to the front end of the device body. The first guide passage is provided with a first ejection pin that moves linearly back and forth in response to the swinging motion of the drive arm, and the second guide passage is provided with a second ejection pin made of a flexible member that moves back and forth in response to the swinging motion of the drive arm. The first ejection pin has an insertion head having an appropriate engagement portion at one end of a separately supplied flexible thread body portion having a predetermined length, and a locking portion for irreversibly inserting and fitting the insertion head into the other end of the thread body portion. The second ejection pin is configured to come into contact with the insertion head of an individual loop pin having a socket portion with a hole provided therein, which is loaded and supplied into the first guide passage, and to eject the insertion head linearly to the outside of the device main body in response to operation of the grip lever, while the second ejection pin is configured to come into contact with the socket portion separately loaded and supplied into the second guide passage, and to be connected to the open end of the device main body of the second ejection pin, and to have its tip end positioned on the ejection direction line of the insertion head. In a locking piece attaching device configured to move and slide the socket portion within a guide member in response to operation of the grip lever to a fitting position with the insertion head portion, and to fit the insertion head portion and the socket portion at that position, the bottom portion of the gap formed between the first guide passage portion and the second guide passage portion is removed to provide a space release portion facing downwards of the device main body portion, or to provide a space release portion facing the front end direction and downwards of the device main body portion, and a second aspect of the present invention is as follows:This loop pin has a flexible thread body having a predetermined length, one end of which is provided with an insertion head having an appropriate engaging portion near the tip, and the other end of which is provided with a socket having a fitting hole in which a locking portion is provided for irreversibly inserting and fitting the insertion head, wherein the one end of the thread body is connected and fixed at a desired position of the insertion head in a direction perpendicular to the central axis of the insertion head, while the other end of the thread is connected to the socket on the same plane as the surface on which the fitting hole of the insertion head formed in the socket is formed or in a portion 4 adjacent thereto. [Effects of the Invention]

[0028] As a result of adopting the novel and innovative technical configuration described above, the locking piece attaching device and loop pins used therein according to the present invention are easier to operate than conventional locking piece attaching devices, and are able to actively prevent the filament portions of adjacent loop pins from becoming entangled. This reduces the chance of the filament portions becoming entangled, and even if an entanglement does occur, it is possible to easily resolve the entanglement. In addition, it is possible to easily and quickly remove the loop pins from the locking piece attaching device even while they are in the entangled state, thereby improving the efficiency of the locking piece attaching operation and achieving the effects of productivity and cost reduction.

DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, specific examples of the locking piece attaching device according to the present invention and the loop pin preferably used in the locking piece attaching device will be described in detail with reference to the drawings. First, a preferred embodiment of the locking piece attaching device 100 according to the present invention will be described in detail with reference to FIGS. That is, as shown in Figs. 1 and 4, the locking piece attaching device 100 according to the present invention comprises a grip lever 12 pivotally supported on a grip portion 11 provided on a device main body 10, a drive arm 13 rotated by the grip lever 12, a first guide passage 42 disposed within the device main body 10 and extending from the vicinity of a rear end portion 40 of the device main body 10 to a front end portion 41 of the device main body 10 along the longitudinal direction of the device main body 10, and a second guide passage 42 disposed substantially parallel to the first guide passage 42 with a predetermined gap therebetween, A second guide passage 43 is provided extending from the vicinity of the rear end 40 of the main body 10 to the front end 41 of the device main body 10, and a first drive pin 16 that moves linearly back and forth in response to the swinging motion of the drive arm 13 is provided within the first guide passage 42, and a second drive pin 19 made of a flexible member that moves back and forth in response to the swinging motion of the drive arm 13 is provided within the second guide passage 43, and the first drive pin 16 has an appropriate engagement portion that engages with one end 60 of a separately supplied flexible thread body 2 having a predetermined length. The second ejection pin 19 is configured to abut against the inserting head 3 loaded and supplied into the first guide passage 42 of each loop pin 1, which is provided with an inserting head 3 having a hole 4 with an engaging portion 6 for irreversibly inserting and fitting the inserting head 3 into the other end 30 of the thread body portion 2, and to eject the inserting head 3 linearly out of the device main body portion 10 in response to the operation of the grip lever 12, while the second ejection pin 19 abuts against the socket portion 5 separately loaded and supplied into the second guide passage 43, and to eject the inserting head 3 linearly out of the device main body portion 10 in response to the operation of the grip lever 12. In the locking piece attaching device 100, the socket portion 5 is slidably moved to a fitting portion 54 with the insertion head 3 in response to the operation of the grip lever 12 within a curved hollow guide member 20 which is fixedly installed so that the tip portion 51 is connected to the open end 41 of the device body 10 of the ejection pin 19 and is positioned on the ejection direction line of the insertion head 3, and the socket portion 5 is fitted to the insertion head 3 at that portion 54.The locking piece attachment device 100 is characterized in that the locking piece attachment portion 102 is removed and a space release portion 200 is provided facing downward from the device main body 10, or a space release portion 200 is provided facing both the front end portion and downward from the device main body.

[0031] That is, in the present invention, in the conventional locking piece attaching device 100, as shown in FIG. 10 or FIG. 11, etc., in the gap 70 formed between the side wall surface including the first guide passage 42 and the side wall surface including the second guide passage 43 of the conventional locking piece attaching device 100, there are flat or inclined bottom surface portions 101, 102 as shown in the respective drawings, and as described above, the flexible thread body portion 2 such as a filament constituting each of the loop pins 1 is arranged in a curved shape, and the curved portions of the thread body portion 2 are mutually curved. When stacked and multi-layered, the loop pins 1 are constantly or irregularly in contact with the bottom surface portions 101, 102 inside the gap portion 70, and the curved portions of the stacked adjacent thread body portions 2 are displaced, moved, or bounced relative to each other due to external forces, vibrations, pressure, etc. that they receive continuously or intermittently from the bottom surface portions, causing the curved portions of the thread body portions 2 to become entangled, joined, or intertwined with each other, preventing the smooth sliding and movement of each individual loop pin 1 and making it impossible to perform the intended fitting operation of the loop pins 1 or resulting in an incomplete fitting state. In order to improve the occurrence of such a situation, the inventor of the present application has, as described above and shown in Figure 1 or Figure 4, removed the flat or inclined bottom portions 101, 102 that constitute the bottom portion of the gap portion 70 formed between the side wall surface including the first guide passage 42 of the locking piece attachment device 100 and the side wall surface including the second guide passage 43, thereby forming a space release portion 200 that is open at least downwardly of the device main body portion 10. In the present invention, it is preferable to provide a space release portion facing both the front end direction and the downward direction of the device main body, which is one of the more desirable examples in terms of work efficiency.

[0032] The width, depth and vertical length of the space release portion 200 in the present invention are not particularly limited, but it is desirable that the space release portion 200 penetrates approximately vertically from the top surface to the bottom end surface of the device main body 10 of the locking piece attachment device 100 of the present invention. In this case, when the locking piece attaching device 100 is viewed from above, the cross section of the space releasing portion 200 has a square shape. Furthermore, in the locking piece attachment device 100 of the present invention, as is clear from Figure 7, it is also a preferred example to provide an opening at the tip 41 of the device main body 10, and in this case, when the locking piece attachment device 100 is viewed from above, the cross-sectional shape of the space release portion 200 is U-shaped. By adopting such a configuration, the locking piece attaching device of the present invention, in the loop pin assembly 9 formed by integrating multiple loop pins 1 mounted on the locking piece attaching device 100 of the present invention, the curved thread body portions 2 formed by each of the loop pins 1 are reliably prevented from having the above-mentioned problems that occurred in the prior art, and as a result, it is possible to receive the firing operation of each loop pin while reliably maintaining an orderly stacked state, so that the problem of the insertion head 3 and socket portion 5 of the loop pin 1 not being properly engaged, or the entanglement or joining of adjacent loop pins 1 making it impossible to remove from the locking piece attaching device 100 those for which the insertion head 3 and socket portion 5 were properly engaged or those for which the engagement was not properly performed, is also solved.

[0033] In other words, in the past, when a malfunction such as that described above occurred and an attempt was made to remove the improperly fitted loop pin 1 from the locking piece attaching device 100, the only solution was to manually pull out the improperly fitted loop pin 1 in the direction of the front end 41 of the device main body 10 of the locking piece attaching device 100, because, as described above, the conventional locking piece attaching device 100 has a bottom surface 101 or 102 in the gap 70 of the locking piece attaching device 100. However, in this method of removing an improperly fitted loop pin 1 by moving it in a direction perpendicular to the arrangement direction of the loop pins 1, the thread-like body portion 2 that forms the curved portion of each adjacent loop pin 1 that is entangled with each other is pulled out while it is still entangled, which makes the entanglement even stronger and makes pulling out more difficult.As a result, it becomes necessary to temporarily stop the hammering operation, remove the loop pin assembly 9 from the locking piece attaching device 100, and manually remove the loop pin 1 that is improperly fitted or cannot be fitted, which is an inefficient correction process.

[0034] In contrast to this, in the present invention, as described above, the locking piece attaching device 100 is provided with the space release portion 200 having the above-described configuration, so that in the event of a faulty fitting operation, the faulty loop pin 1 can be easily separated and removed from the locking piece attaching device 100 by manually pulling out the faulty loop pin 1 from the lower open end of the space release portion 200. In this configuration, the loop pin 1 that has become improperly fitted can be pulled out parallel to the stacking direction while the filamentous body portions 2 that are formed and arranged in a curved shape in each loop pin 1 are stacked in multiple consecutive layers, so that the pulling-out and removal operation can be easily performed without further promoting the entangled state during the pulling-out operation.

[0035] In addition, it is desirable that the flexible thread portion 2 constituting the loop pin 1 used in the locking piece attaching device 100 in the present invention is composed of a plastic filament or thread-like body, and it is also a preferred example that the thread portion 2 in the loop pin 1 referred to in the present invention is composed of a twisted thread-like body that is a thread made of natural or synthetic fibers, or is composed of one material or a combination of materials selected from the group consisting of braided cord, knitted cord, paper cord, twisted paper, and vegetable fiber thread-like thread. In particular, in the present invention, it is particularly preferable to use a filamentous body part that has as little environmental impact as possible, and from that perspective, it is desirable to use a filamentous body part made from natural materials as the filamentous body part used in the present invention. Furthermore, with regard to the locking piece mounting device 100 of the present invention, the above-mentioned specific example has been described as a locking piece mounting device having the configuration shown in Figures 4 to 6, but it goes without saying that the same effect can be obtained with a locking piece mounting device having a configuration in which the horizontal plane formed by the first guide passage portion 42 and the horizontal plane formed by the second guide passage portion 43 are arranged so as to be different from each other, as shown in Figures 1 to 3.

[0036] Next, as a result of further intensive research into improvements to the operation of the above-mentioned locking piece attaching device 100 and the technology for preventing improper fitting, the present inventors have found that, in order to prevent the entanglement of the thread-like body portions 2 when the loop pins 1 are fired out, a more preferable effect can be obtained by fixing and arranging a long guide member 300 of an appropriate length in the space releasing portion 200 at a position corresponding to the inside of the curved portion of each flexible thread body portion 2 of the multiple loop pins 1 mounted on the device main body 10, as shown in Figure 8, which passes through the space releasing portion 200 and extends along the vertical axis direction of the device main body 10 or a direction approximate thereto. The material constituting the guide member 300 is not particularly limited, and it is desirable to set it at any position as long as the condition that it is positioned so as to contact the inside of the curved portion of each thread body portion 2 in the curved loop pin 1 is satisfied. Furthermore, one desirable example of the guide member 300 is that one end 301 thereof is fixed and held in the vicinity of the portion at the front end of the device main body 10 where the opening end 41 of the first guide passage 42 or the second guide passage 43 is formed, and that the guide member 300 is fixed and held to the tip end 303 of a support member 302 which is arranged extending from the one end 301 within the space release portion 200. In a specific example, it is desirable that the length of the portion of the guide member 300 formed above the support member 302 is set to be the same as or longer than the longitudinal length of the connection bar 8 that fixes and holds the multiple loop pin groups 9 used.

[0037] Furthermore, in this specific example, it is desirable that the length of the portion of the guide member 300 formed below the support member 302 is set to a length equal to the length of at least the multiple loop pins 1 used arranged in parallel. FIG. 9 is a perspective view showing the state in which the loop pin assembly 9 consisting of the loop pin group is attached to the locking piece attaching device 100 shown in FIG. 8 in another embodiment of the present invention described above. Furthermore, in the present invention, in order to promote stabilization so that the filament-like body portions 2 of each loop pin 1 do not become entangled, engaged, or joined together when the loop pin assembly 9 mounted on the locking piece attaching device 100 swings irregularly due to the various movements, displacements, and vibrations during operation, one preferred example is to provide an appropriate auxiliary engaging means 305 in the vicinity 40 of the rear end portion of the device main body 10 of the locking piece attaching device 100, as shown in Figure 23, so that the tip portion of the guide member 300 used in the present invention described above can be engaged, and the guide member 300 is forcibly held and fixed in a curved state.

[0038] Next, during the course of research into solving the problems in the prior art described above, the present inventors realized that in addition to the configuration of the locking piece attaching device 100, it was also essential to improve the structure of the loop pin 1 itself that is mounted on the locking piece attaching device 100.As a result of extensive research into this point, they have succeeded in developing a loop pin 1 with a structure that is suitable for use with the locking piece attaching device 100 in the present invention described above. That is, the second aspect of the present invention is a loop pin 1 that can be mounted on the locking piece attaching device 100 according to the first aspect of the present invention and used effectively and efficiently, and the loop pin 1 can be used under conditions where the operation of attaching a tag or the like is efficient and the occurrence of incomplete fitting is low. The loop pin 1 has a structure in which an insertion head 3 having an appropriate engagement portion 6 near the tip is provided on one end 60 of a flexible thread body portion 2 having a predetermined length, and the other end 30 of the thread body portion 2 has a hole 30 for irreversibly inserting and fitting the insertion head 3. The loop pin (1) is provided with a socket portion (5) having a fitting hole portion (4) provided with a locking portion (6) for fastening the one end (60) of the filament body portion (2) at an appropriate portion of the insertion head portion (3) in a direction perpendicular to the central axis direction (P) of the insertion head portion (3), and the other end (30) of the filament body portion (2) is connected and fixed on the same plane as or in the vicinity of the surface (205) of the socket portion (5) on which the fitting hole portion (4) of the insertion head portion (3) is formed.

[0039] The configuration of the novel loop pin 1 will be explained in more detail with reference to the drawings. A desirable configuration of the novel loop pin 1 is, as shown in Figure 24, a loop pin 1 in which one end 60 of a flexible thread body portion 2 having a predetermined length is provided with an insertion head portion 3 having an appropriate engaging portion 6 near its tip, and the other end 30 of the thread body portion 2 is provided with a socket portion 5 having an engagement hole portion (hole portion) 4 with a locking portion 116 for irreversibly inserting and fitting the insertion head portion 6, and the one end 60 of the thread body portion 2 is connected and fixed at an appropriate position of the insertion head portion 3 in a direction perpendicular to the central axis P of the insertion head portion 3, while the other end 30 of the thread body portion 2 is connected to the socket portion 5 on the same plane as or in the vicinity of a surface 205 on which the engagement hole portion 4 of the insertion head portion 3 is formed in the socket portion 5. In the loop pin 1 of the second embodiment of the present invention, the portion of the insertion head 3 to which one end 60 of the thread body portion 2 is joined and the connection portion of the socket portion 5 to which the other end 30 of the thread body portion 2 is joined on the surface 205 on which the fitting hole 4 of the insertion head 3 is formed are not particularly limited and any portion can be selected. However, particularly in the present invention, when the thread body portion 2 is a highly flexible filament made of a filament containing twisted yarns made of natural or synthetic fibers, a braided cord, a knitted cord, a paper cord, a twisted paper cord, or a vegetable fiber filament, it is desirable to arrange it in the portion shown by the solid line 2 in Figure 24, and by adopting such a configuration, the loop pin 1 can be manufactured at high speed and continuously.

[0040] On the other hand, in the present invention, when the thread body portion 2 is composed of a filament made of synthetic resin, it is also desirable that the attachment portion of the thread body portion 2 be positioned at a location such as that shown by the solid line 2' in Figure 24. Furthermore, in the present invention, one end 60 of the thread body portion 2 is connected to the insertion head 3 in a direction perpendicular to the central axis P of the insertion head 3, and the thread-like body portion 2 is connected perpendicularly to the same surface as the surface 205 of the socket portion 5 on which the fitting hole 4 of the insertion head 3 is formed. This completely prevents the occurrence of one of the problems in the prior art described above, in which a part of the thread-like body portion 2 of the loop pin 1 that was previously launched within the first guide passage 42 described in Figure 21 becomes entangled with the insertion head 3 of the subsequent loop pin 1 that has descended to be launched thereafter, at the insertion head fitting opening 53 within the first guide passage 42, and the two pins become difficult to move due to the fit.

[0041] The reason for this is that, as shown in Figure 22, the filamentous body portion 2 connected to the insertion head 3 as described above is attached in a direction perpendicular to the central axis P of the insertion head 3, so that the filamentous body portion 2 is prevented from being pulled into the insertion head insertion opening 53 of the first guide passage 42 due to the influence of the filamentous shape Q of the orthogonal connection portion and its surrounding area, and at the same time, the structure sets the filamentous body portion 2 in a curved state with greater strength than in conventional technology, thereby more firmly stabilizing the curved shape of the filamentous body portion 2. Furthermore, it is desirable that the filament portion 2 in the loop pin 2 of the present invention has a moderate degree of flexibility, and a preferred example of the flexible filament 2 is made of a plastic filament or a normal filament.Furthermore, a preferred example of the filament in the present invention is made of one material or a combination of materials selected from the group consisting of filaments made of natural or synthetic fibers, braided cords, knitted cords, paper cords, twisted paper, and plant fiber filaments.

[0042] Furthermore, in the present invention, a preferred embodiment for performing tag attachment operations is that the loop pins 1 of the present invention form a loop pin assembly 9 in which a plurality of the loop pins are arranged in parallel with each other with the thread body portion 2 in a straight line, forming a group of loop pins. As shown in Figure 25, in the loop pin assembly 9, each of the insertion head portions 3 of the plurality of loop pins 1 is connected and fixed to a long first connection bar portion 8 (also called a runner bar) having an arbitrary cross-sectional shape via a connection link portion 111 having an appropriate shape and configured to be easily broken by a small external force, while each of the socket portions 5 of the plurality of loop pins 1 is connected and fixed to a long second connection bar portion 8' (also called a runner bar) having an arbitrary cross-sectional shape via a connection link portion 111' having an appropriate shape and configured to be easily broken by a small external force.

[0043] As is clear from the above explanation, in this invention, the structural improvements to the locking piece attachment device and the structural improvements to the loop pin as described above, either as a result of their individual effects or as a result of their synergistic effect, do not pursue a solution to prevent the entanglement of the thread-like body portions in the loop pin, which has been a problem in the past, but rather fundamentally eliminate the cause of such entanglement in principle and complete a technology that theoretically makes the operation of firing the loop pin perfect.
