Description

[Technical Field]

[0001] The present invention relates to a bundling device for linear objects. [Background Art]

[0002] Patent Document 1 describes a device for bundling a plurality of linear objects such as pasta, Japanese noodles, incense sticks, and wire. In this device, a plurality of linear objects are grasped by closing a plurality of chucks, and a binding tape is wound around the outer periphery of the plurality of linear objects by rotating the chucks. The binding tape wound around the plurality of linear objects is heat-sealed by a heater and cut by a cutter portion. [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-79953 [Summary of the Invention] [Problems to be Solved by the Invention]

[0004] In the device shown in Patent Document 1, when welding the binding tape, the heater is brought into contact. After the heater is brought into contact with the binding tape for a predetermined time, the heater is separated from the binding tape to end the heat welding. In such a device, when welding the binding tape, the position of the binding tape may shift, and the shape of the binding tape may be disturbed at the heat welding portion, which may impair the appearance of the bundled product.

[0005] An object of the present invention is to provide a bundling device for linear objects that can prevent poor fixation of the tape when welding the tape to bundle a plurality of linear objects and can weld the tape beautifully. [Means for Solving the Problems]

[0006] The present invention provides a device for bundling multiple linear objects by heat-welding tape wrapped around them, and the device includes a rotating part, the rotating part which rotates in a direction approaching or moving away from the tape wrapped around the multiple linear objects and holds the tape in place, and a heating part which rotates in a direction approaching or moving away from the tape wrapped around the multiple linear objects and heats the tape wrapped around the multiple linear objects to weld it, thereby solving the above problem. In this device, by holding the melted tape in place with the pressing part, it is possible to prevent distortion of the shape of the bundling tape at the welded part and its surrounding area, prevent poor fixing of the bundling tape, and enable the bundling of multiple linear objects in an aesthetically pleasing manner.

[0007] In the above-described apparatus, the following configuration is preferable. That is, after the tape is welded, the pressing part is a linear object binding device that operates so as to rotate away from the tape after the heating part has separated from the tape and with a delay from the heating part. With this configuration, the tape can be held in place by the pressing part when the heating part separates from the tape, so it is possible to more reliably prevent defects in fixing the tape and to weld the binding tape in an aesthetically pleasing manner.

[0008] In the above-described apparatus, the heating unit is fixed to a power-transmitting shaft and rotates integrally with the shaft, while the pressing unit is supported on the shaft in a state where it can rotate relative to the shaft. The pressing unit can be configured to be biased toward the linear objects by a spring that rotates integrally with the heating unit when the heating unit rotates toward the linear objects. With this configuration, the pressing unit can be rotated in conjunction with the rotation of the heating unit with a simple configuration. Furthermore, with this configuration, the pressing unit can be brought into contact with the tape wound around the multiple linear objects with appropriate pressure by utilizing the spring force.

[0009] In the above-described apparatus, the pressing portion is provided with a through hole through which the heating portion passes, and the heating portion can be configured to contact the tape within the area surrounded by the through hole in the pressing portion. With this configuration, welding can be performed in the portion where the tape is in closer contact with multiple linear objects, and welding defects can be prevented more effectively.

[0010] In the above-described apparatus, the heating element can be configured to be biased toward the plurality of linear objects. With this configuration, the heating element can be brought into contact with the plurality of linear objects at an appropriate pressure. With this configuration, the heating element can make strong contact with the plurality of linear objects, preventing damage to the plurality of linear objects. [Effects of the Invention]

[0011] According to the present invention, when fastening tape to bundle multiple linear objects, it is possible to provide a device for bundling linear objects that prevents defects in tape fixation and enables aesthetically pleasing tape fastening. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0013] Hereinafter, embodiments of the linear material bundling device of the present invention will be described. The embodiments shown below are merely limited examples of the linear material bundling device of the present invention, and the technical scope of the present invention is not limited to the illustrated embodiments.

[0014] FIGS. 1 to 17 show an embodiment of a linear material bundling device 1 (hereinafter, may be simply referred to as a bundling device). The bundling device 1 includes a rotating part 11, a holding part 2 for a plurality of linear materials 12, and a tape feeding part 3 for a tape 31.

[0015] The rotating part 11 rotates in a direction approaching or separating from the tape wound around the plurality of linear materials, and includes a pressing part 112 for pressing the tape 31, and a heating part 111 that rotates in a direction approaching or separating from the tape 31 wound around the plurality of linear materials 12 (hereinafter, may be simply referred to as linear materials) and heats and welds the tape 31 wound around the plurality of linear materials 12.

[0016] The plurality of linear materials are an aggregation of linear objects. The linear materials are likely to come apart and difficult to handle in the aggregated state. By bundling the plurality of linear materials 12 with the tape 31, it becomes much easier to handle. The linear materials are not particularly limited, and examples include dried noodles such as soba noodles, udon noodles, pasta, or ramen noodles, incense sticks, or wires.

[0017] The holding part is a member that holds multiple linear objects. In the example shown in Figures 1 to 4, the holding part 2 is composed of multiple gripping parts 21. Each gripping part 21 has an inner shape that conforms to the outer shape of the multiple linear objects that are stacked together. The multiple gripping parts 21 are joined together to hold the multiple linear objects 12. The gripping parts 21 function like a chuck, which is a mechanical element. The holding part 2 is configured to be rotatable in the circumferential direction of the multiple linear objects. One of the gripping parts 21 is provided with a pin 22 as a tape retainer that protrudes along the longitudinal direction of the linear object 12.

[0018] Multiple holding parts may be provided, spaced apart along the longitudinal direction of multiple linear objects. For example, by holding a linear object with two holding parts 2 spaced apart along its longitudinal direction, the linear object can be held stably.

[0019] The tape dispensing section 3 of the tape 31 is the part that supplies the tape wound on a roll (not shown) to the linear object 12. In the examples of Figures 1 to 4, the dispensing section 3 is rod-shaped and dispenses the tape 31 from its tip. The dispensing section 3 is configured to be movable from a first position near the rotating section 11, through the top of the linear object 12, to a second position on the opposite side of the rotating section 11. The tape can be any known heat-sealable tape. Examples of heat-sealable tapes include those made of thermoplastic resins such as polyethylene, or those made by coating materials such as Japanese paper with a thermoplastic resin such as polyethylene.

[0020] The process of winding the tape 31 around the linear object 12 will now be described. As shown in Figures 1 and 2, the gripping part 21 holds the linear object. At this time, the leading edge of the tape 31 that has been unwound from the dispensing part 3 is sandwiched between the pin 22 and the linear object 12. With the tape 31 sandwiched between the pin 22 and the linear object 12, the holding part 2 is rotated in the circumferential direction of the linear object 12, as indicated by the arrow in Figure 3, to wind the tape 31 around the linear object 12. During the process of winding the tape 31 around the linear object 12, the dispensing part 3 moves from the first position described above to the second position described above, as shown in Figure 4, and retracts so as not to interfere with the rotating part 11.

[0021] As shown in Figures 5 to 7, the rotating part 11 includes a heating part 111 and a pressing part 112.

[0022] The pressing portion 112 has an arc-shaped plate-like portion that conforms to the outer shape of the multiple linear objects 12, and has a hole that penetrates the arc-shaped portion of the plate-like portion. This through hole is shaped so that the heating portion 111 can pass through. With this configuration, the heating portion 111 can be brought into contact with the tape 31 within the area surrounded by the through hole of the pressing portion 112, so that heat welding can be performed with the tape 31 in close contact with the multiple linear objects 12, and the occurrence of welding defects of the tape 31 during welding can be prevented.

[0023] As shown in Figure 6, the heating element 111 is rod-shaped and has a tapered section that narrows towards the tip, with the tip being shaped like a truncated cone.

[0024] As shown in Figure 7, the heating unit 111 is structured to rotate integrally with the power-transmitting shaft 113 and the first rotating unit 41 in a direction approaching or moving away from a linear object. The heating unit 111 is fixed to the tip of the first rotating unit 41. The base end of the first rotating unit 41 is fixed to the power-transmitting shaft 113 of the cam 51, which will be described later, by a screw 511. The base end of the first rotating unit 41 is provided with a shaft hole through which the shaft 113 is inserted. The shaft 113 and the first rotating unit 41 are fixed by screwing the screw in from the outside of the shaft hole so as to contact the circumferential surface of the shaft 113 inserted into the shaft hole. The end of the shaft 113 inserted into the shaft hole of the first rotating unit 41 protrudes from the end of the first rotating unit 41. The portion of the shaft 113 that protrudes from the base end is inserted into the shaft hole at the base end of the second rotating part 42, as will be described later.

[0025] As shown in Figures 6 and 7, the first rotating part 41 has a support part 117 that supports the heating part 111, a bracket 125 that connects the support part 117 and the connecting part 115, and a connecting part 115 that connects the bracket 125 and the shaft part 113. The support part 117 that houses the base end of the heating part 111 is block-shaped. A blade 119 is fixed to the front surface of the support part 117. The support part 117 is provided with a hole, in which the spring 123 and the heating part 111 are housed. The base end of the heating part 111 is biased by the spring 123 and is configured to contact the linear object 12 around which the tape 31 is wound with appropriate pressure. The connecting portion 115 has a shaft hole at its base end for inserting the shaft portion 113, a receiving portion 126 for the latching portion 127 of the second rotating portion 42 (described later), and a receiving portion 128 for the spring 124 (described later). The heating portion 111, the support portion 117, the bracket 125, the connecting portion 115, and the shaft portion 113 rotate together as a single unit.

[0026] The shape of the latching portion 127 is such that it can latch onto the first rotating portion 41, and in the example of Figure 7, it is a rod shape with a stepped portion at its tip. The shape of the receiving portion is such that it can latch onto the latching portion, and in the example of Figure 7, it is a recess. The shape of the receiving portion is such that it can receive the end of the spring, and in the example of Figure 7, the receiving portion 128 is a plate-shaped portion protruding from the connecting portion, and the receiving portion 129 is a plate-shaped portion protruding from the connecting portion 116. The plate-shaped portion is provided with a projection for holding the spring.

[0027] The pressing portion 112 rotates around the shaft portion 113 shown in Figure 7 in a direction that moves it closer to or away from the linear object 12. The pressing portion 112 rotates around the shaft portion 113. As shown in Figures 6 and 7, the pressing portion 112 is fixed to the tip of the second rotating portion 42. The base end of the second rotating portion 42 is rotatably supported by the shaft portion 113.

[0028] As shown in Figures 6 and 7, the second rotating part 42 has a bracket 118 for fixing the retaining part 112, a block-shaped support part 120 for fixing the bracket 118, and a connecting part 116 which has a shaft hole at its base end through which the shaft part 113 is inserted, a hooking part 127 for the first rotating part 41 at its upper end, and a spring receiving part 129 at its tip. The retaining part 112, bracket 118, support part 120, and connecting part 116 rotate together as a unit around the shaft part 113. The shaft part 113 and the connecting part 116 are inserted in a rotatable state and are not completely fixed, and the second rotating part 42 is configured to slide on the shaft part 113 and rotate independently of the shaft part 113. The outer diameter of both ends of the shaft part 113 is smaller than that of the central part. The portion of the shaft 113 with a smaller outer diameter protrudes from the connecting portion 115, and the protruding portion of the shaft 113 is inserted into the shaft hole of the connecting portion 116. The small-diameter portions at both ends of the shaft 113 can be constructed, for example, by fitting another pipe material with a relatively smaller outer diameter into a pipe material with a relatively larger outer diameter. Alternatively, the small-diameter portion and the large-diameter portion may be integrally constructed by appropriate means such as cutting.

[0029] The cam mechanism for rotating the shaft portion 113 will now be described. As shown in Figures 14 to 17, the cam mechanism comprises a cam 51 that is driven by a drive source such as a motor and rotates in the forward or reverse direction around the shaft 56, and a first driven link 53 and a second driven link 54 that have contacts 52 that contact the cam 51.

[0030] The upper end of the first driven link 53 is supported by a fixed shaft, and the first driven link 53 is supported in a state that allows it to swing in a direction toward or toward the cam 51. The lower end of the first driven link 53 is fixed to the upper end of the second driven link 54 by a shaft 55. The first driven link 53 and the second driven link 54 constitute a link mechanism. A contact element 52 is provided in the middle of the first driven link 53.

[0031] As shown by the arrows in Figure 14, when the cam 51 rotates, the contactor 52, which was biased to approach the cam 51 by a spring (not shown), moves in the direction of approaching the cam 51, as shown in Figure 16. As a result, the shaft 55 at the lower end of the first driven link 53 moves to a position closer to the shaft 56 of the cam 51, and the upper end of the second driven link 54 also moves to a position closer to the shaft 56 of the cam 51. The lower end of the second driven link 54 is fixed to the shaft portion 113. The lower end of the second driven link 54 is fixed in position, and the oscillating motion of the second driven link 54 caused by the cam 51 is converted into the rotational motion of the first rotating part 41 via the shaft portion 113 connected to the lower end of the second driven link 54.

[0032] As a result of the operation of the cam 51 described above, the rotating part 11 rotates from a state separated from the multiple linear objects 12, as shown in Figure 15, to a state approaching the multiple linear objects 12, as shown in Figure 17.

[0033] As the cam 51 rotates further in the clockwise direction indicated by the arrow in Figure 14 from the state shown in Figure 16, the first driven link 53 moves so that the shaft 56 of the cam 51 and the contact 52 are separated, as shown in Figure 14. The upper end of the second driven link 54 also moves to a position separated from the shaft 56 of the cam 51. The lower end of the second driven link 54 is fixed to the shaft portion 113. The oscillating motion of the second driven link 54 caused by the cam 51 is converted into the rotational motion of the first rotating part 41 via the shaft portion 113 connected to the lower end of the second driven link 54.

[0034] As a result of the operation of the cam 51 described above, the rotating part 11 rotates from a state in contact with the multiple linear objects 12 as shown in Figure 17 to a direction away from the multiple linear objects 12 as shown in Figure 15.

[0035] As described above, by rotating the cam in one direction, the position of the contact element 52 changes periodically, and the position of the rotating part also changes periodically. The position of the rotating part may also be changed by switching the direction of rotation of the cam. With the configuration described above, in which the attitude of the rotating part is controlled by rotation in one direction, control of the drive unit is unnecessary. As shown in Figure 14, the cam 51 is provided with a guide part that contacts the contact element 52 and guides the movement of the contact element 52. In Figure 16, the guide part is shown in a state where a part of it has been broken.

[0036] The process of welding the tape 31 will be explained with reference to Figures 4 and 8 to 13. As shown in Figure 4, the tape 31 dispensing unit 3 retracts to the second position after winding the tape 31 around the linear object 12. Due to the operation of the cam 51 described above, the rotating unit 11 rotates from the state in Figure 4 in a direction approaching the multiple linear objects 12. Specifically, as the cam 51 rotates, the first rotating unit 41, which has a heating unit 111, rotates around the shaft 113. The second rotating unit 42, which has a pressing unit 112, is rotatably supported with respect to the shaft 113, but is pushed by a spring 124 provided between the first rotating unit 41 and the second rotating unit 42, and rotates together with the first rotating unit 41 until the pressing unit 112 contacts the linear object 12.

[0037] As shown in Figure 8, when the pressing part 112 comes into contact with the linear object 12, the rotational movement of the second rotating part 42 and the pressing part 112 stops. The second rotating part 42 is merely pushed by the spring 124 and rotates together with the first rotating part 41, and is not directly driven by the cam 51 and the shaft part 113. Therefore, when the pressing part 112 comes into contact with the linear object 12, the rotation of the second rotating part 42 stops, and the connecting part 116 (Figure 7) and the shaft part 113 slide against each other, while the first rotating part 41 and the heating part 111 are driven by the cam 51 and rotate further in the direction approaching the linear object 12, as shown in Figure 9.

[0038] As shown in Figure 9, when the heating element 111 touches the tape 31, the tape 31 is welded to it by the heat of the heating element 111. As shown in Figure 6, the support element 117 that supports the heating element 111 is provided with a hole for inserting the heating element of the cartridge heater. Due to the heat from the heating element, the surface of the support element 117 and the heating element become hot.

[0039] The first rotating part 41 and the heating part 111 are further rotated by the cam 51 in a direction that approaches the plurality of linear objects 12, as shown in Figure 10, when the heating part 111 provided on the first rotating part 41 comes into contact with the tape 31 wound around the linear objects 12, the heating part 111 sinks into the support part 117, compressing the spring 123 built into the support part 117, and the blade 119 fixed to the support part 117 comes into contact with the tape 31. The tape 31 is cut by the blade 119. While the spring 123 is compressed, the heating part 111 remains in contact with the tape 31, and the tape is sufficiently melted.

[0040] As shown in Figure 10, the first rotating part 41 and the second rotating part 42 are provided with spring receiving parts, and a spring 124 is fixed between the receiving part 128 of the first rotating part 41 and the receiving part 129 of the second rotating part 42. After the pressing part 112 makes contact with the linear object 12, when the first rotating part 41 rotates in a direction approaching the linear object 12, the first rotating part 41 rotates further to approach the second rotating part 42, which has stopped rotating. At this time, the spring 124 is compressed. The pressing part 112 is pressed so that it comes into close contact with the tape 31 by the first rotating part 41 rotating to approach the linear object 12 and the spring force of the spring 124. As a result, the tape 31 is properly pressed down so that it does not lift away from the linear object 12.

[0041] As shown in Figure 11, when the cam 51 rotates as shown in Figure 16, the first rotating part 41 rotates first in a direction away from the tape 31. Until the spring 124 is fully extended, the pressing part 112 holds the tape 31 in place due to the biasing force of the spring 124. The rotation of the first rotating part 41 causes the heating part 111 to rotate away from the tape 31. At this time, the spring 124 that was holding the pressing part 112 gradually extends. As the cam 51 rotates further and the spring extends to its original length, the pressing part 112 and the second rotating part 42 begin to rotate together in a direction away from the linear object 12, as shown in Figure 12. At this time, the locking portion 127 of the second rotating portion 42 locks onto the receiving portion 126 of the first rotating portion 41, causing the first rotating portion 41 and the second rotating portion 42 to rotate together in a direction away from the multiple linear objects. In this way, the pressing portion 112 rotates in a direction away from the linear objects 12, but with a delay compared to the heating portion 111. This makes it possible to hold the tape with the pressing portion 112 until, for example, the temperature of the molten tape decreases even slightly. It also makes it possible to hold the tape 31 with the pressing portion until the heating portion 111 separates from the molten tape. This prevents, for example, when separating the heating portion 111 from the tape 31, the molten tape 31 from adhering to the heating portion 111 and being pulled, which can disrupt the shape of the welded portion of the tape 31 or cause the molten tape to melt before it solidifies.

[0042] As shown in Figure 13, when the rotating part 11 is sufficiently separated from the linear object 12, the holding part 2 separates each gripping part 21 from the linear object 12, causing the linear object 12, which is bound with tape 31, to fall downward. The fallen linear object is received by a transport means such as an endless track and transported to a device for the next process.

[0043] In conventional binding devices, for example, when separating the heater from the tape, the molten tape could adhere to the heater and be pulled, causing perforations or unraveling of the tape. Also, in conventional binding devices, for example, when separating the heater from the tape or when the heater is brought into contact with the tape, the position of the tape could shift, causing the joined shape of the tape to collapse at the heat-welded portion. Furthermore, in conventional binding devices, the tape could unravel if the heater was separated before the tape had melted and solidified. The binding device of the above embodiment effectively prevents these problems.

[0044] In the above-described binding device, the rotation direction of the rotating part is periodically changed by a cam, but a stopper is also provided as an auxiliary measure. As shown in Figures 15 and 17, a stopper receiving portion 121 is provided at the end of the second rotating part 42. As shown in Figure 17, the rotation of the second rotating part 42 is stopped when the receiving portion 121 and the stopper 122 come into contact. This prevents the linear object 12 from being damaged by excessive rotation of the second rotating part 42. Note that in Figures 1 to 13, the stopper and receiving portion are omitted from the illustration for the sake of simplicity. The stopper and receiving portion can be any component that functions as a rotation restricting part, and are not limited to the above example.

[0045] The shape of the pressing portion 112 is not limited to that of the above embodiment, and may be, for example, as shown in Figures 18 and 19. The pressing portion 112b in Figure 18 has a mountain-fold shape with corners in the part that contacts the linear object 12, and a through hole for passing the heating portion is provided at the top. The pressing portion 112c in Figure 19 has a plate-shaped tip portion that extends in a direction intersecting the extending direction of the pressing portion 112c, and a stepped portion located on the base end side that extends toward the linear object 12. The plate-shaped portion surrounded by the tip portion and the stepped portion contacts the linear object 12. A through hole for passing the heating portion 111 is provided in the plate-shaped portion.

[0046] The shape of the heating section 111 is not limited to that of the above embodiment, and may be, for example, as shown in Figures 21 and 22. In Figure 21, the heating section 111b has a rod shape with a circular cross-section at the base end and an oval cross-section at the tip end. In Figure 22, the heating section 111c has a rod shape with a circular cross-section at the base end and a shape in which multiple rods with circular cross-sections are provided at the tip end. The rods at the tip end have a smaller cross-sectional area compared to the rods at the base end.

[0047] In the above-described binding device, the first rotating part is composed of multiple components. The configuration of the first rotating part is not limited to the above example; it may be composed of a single component, or it may be in an appropriate shape such as an arm or a rod. Similarly, the configuration of the second rotating part is not limited to the above example; it may be composed of a single component, or it may be in an appropriate shape such as an arm or a rod.
