Description

Spacer inserting device, binding system, and binding method for binding band

Technical Field

The present invention relates to an insertion device and an insertion method for a spacer for protecting a base of a binding band for binding a coiled rolled steel band or the like.

Background

Rolled steel strips, pipes, and electric wires, which are industrially used for various purposes, are wound into a coil shape due to restrictions on transportation and the like, and are generally conveyed in a cylindrical shape. At this time, the coiled rolled steel strip or the like is bound by a binding band made of metal or the like so as not to be unwound during conveyance (hereinafter, the article bound by the binding band is also referred to as "object to be bound").

In many cases, such a binding tape is bound so as to surround the periphery of the object to be bound, as disclosed in the patent document described later, or in the case of a hollow object to be bound, the inside and the outside of the object to be bound are connected in the height direction of the object to be bound.

In the above-described binding band, when binding an object to be bound, the leading end portion and the trailing end portion are joined by a joint metal or welding or the like in a state of being overlapped, and therefore, a binding joint portion having a relatively large thickness is formed at this portion.

Since a metal such as a metal is sometimes disposed in the binding joint portion, a sealing gasket (hereinafter, collectively referred to as a "gasket") is interposed between the binding joint portion and the object to be bound so as not to damage the surface of the object to be bound as a product, thereby binding the binding band.

Such a gasket is formed of a resin material such as compressed pulp, styrofoam, or plastic, or felt or woven fabric, and a thin rectangular parallelepiped gasket is also used as the shape thereof. The shim may have various shapes, and for example, in patent document 1, the overall planar shape is configured to be approximately コ -shaped, such as a placement portion 1A for placing the tape 2 on the upper surface 1A, two side pieces 1B extending from both ends of the placement portion 1A in parallel to the tape 2 in the longitudinal direction of the tape 2 and having a space therebetween (between the side pieces), and a notch portion 1C formed by the two side pieces 1B and the placement portion 1A in three directions.

Problems to be solved by the invention

However, not only the above patent documents but also the current techniques cannot appropriately satisfy the market demand, and the above methods have the following problems.

That is, when the spacer is inserted between the binding joint portion and the object to be bound, the spacer is gripped by the claw portions so that the two plate springs face each other, and inserted.

The spacer can be simply inserted between the binding engagement portion and the object to be bound by physically grasping the spacer with a plate spring (claw) or the like, but in this method, one plate spring has to be interposed between the spacer and the object to be bound, and there is a possibility that the surface of the object to be bound is damaged.

In addition, in the above case, even if the surface of the object to be bundled is not damaged, it is undeniable that the plate spring may be deteriorated by friction or the like with the spacer or the object to be bundled due to repeated use.

As shown in patent document 1, the gasket is generally placed horizontally from the upper side toward the lower side in the vertical direction in many cases, but a situation in which the gasket cannot be placed horizontally due to space constraints or the like can also be assumed.

In such a case of placing in a non-horizontal state, the spacer may be simply inserted between the binding engagement portion and the object to be bound by gripping the spacer with the claw portion, and the spacer may slip off.

As described above, the conventional techniques have various problems such as restrictions on the placement form of the gasket, damage to the surface of the object to be bundled, and early deterioration of the device into which the gasket is inserted, and still have room for improvement.

The present invention has been made in view of the above-described problems, and an object thereof is to provide a gasket insertion device, a binding system, and a binding tape binding method, which enable insertion of a gasket even in a non-horizontal state, have a long life, and can greatly suppress damage to the surface of an object to be bound.

In the pad inserting apparatus according to the above (1), it is preferable that (2) the second delivery position is a position at which the holding mechanism unit sucks and holds the pad, and the inserting mechanism unit rotates the first suction and holding unit around a position between the housing mechanism unit and the holding mechanism unit to move the first suction and holding unit between the first delivery position and the second delivery position.

In the pad inserting apparatus according to the above (2), preferably, (3) the inserting mechanism unit linearly moves the first suction holding unit from the first delivery position to the second delivery position in a state where the pad is sucked by the first suction holding unit, and the holding mechanism unit holds the pad positioned at the second delivery position and moves the held pad so as to come into contact with a side of the object to be bundled.

In the gasket insertion device according to the above (3), preferably, (4) the housing mechanism includes an erecting device that erectly positions the gasket at the first delivery position, and the insertion mechanism sucks the gasket erected at the first delivery position by the first suction holding portion and linearly moves the first suction holding portion in a process from the first delivery position to the second delivery position.

In the gasket insertion device according to any one of the above (1) to (4), preferably, (5) the holding mechanism includes a second suction holding portion that sucks the gasket moved to the second delivery position, and the suction of the gasket by the first suction holding portion is released after the second suction holding portion sucks the gasket at the second delivery position.

Detailed Description

Embodiments for carrying out the present invention will be described. In the following description, for convenience, the X direction, the Y direction, and the Z direction are set as shown in the drawings. However, the present invention is not affected by the above-described direction, and it is needless to say that the claims cannot be unduly reduced.

[ first embodiment ]

[ gasket insertion device 100]

A gasket insertion apparatus 100 according to a first embodiment of the present invention will be described with reference to fig. 1 and 3 as appropriate.

As shown in fig. 1, 6, and the like, the gasket insertion device 100 of the present embodiment has a function of inserting a gasket interposed between a binding joint portion and an object 1 to be bound, and is configured to include at least an accommodation mechanism portion 10, an insertion mechanism portion 20, and a holding mechanism portion 30.

Here, the "objects to be bundled" are products bundled by the bundling band at the time of transportation or the like as described above, and examples thereof include rolled steel strips, tubes, metal wires, and the like. As an example, as shown in fig. 1, the diameter D of the object 1 to be bundled may be, for example, about 1000mm to 2000 mm.

The housing mechanism 10, the insertion mechanism 20, and the holding mechanism 30 are held by an apparatus frame 40 described later, and their operations are similarly controlled appropriately by a control apparatus 50 described later.

The housing mechanism 10 has a function of mounting and housing a plurality of pads P and a function of sending one of the stacked pads P to the first delivery position FP.

More specifically, the housing mechanism 10 of the present embodiment includes a housing 11, a pad feeding portion 12, a first stopper 13, and a second stopper 14.

The frame 11 is a rectangular parallelepiped housing for housing the plurality of pads P in a stacked state, and is made of, for example, resin, metal, or the like. As shown in fig. 1, 3, and the like, the pads P are stacked in a flat state in the housing 11, and are fed one by one to the first delivery position FP by a pad feeding unit 12 described later.

As shown in fig. 1, in the present embodiment, the pad sending-out portion 12 is provided on the opposite side of the first delivery position FP side in the housing 11. The pad feeding unit 12 has a function of pressing the stacked pads P toward the first delivery position FP side by an elastic member such as a known spring. Thus, after the pad P is sent out toward the second delivery position SP at the first delivery position FP, the next pad P can be moved toward the first delivery position FP by the pad sending-out unit 12.

As shown in fig. 3 to 5, the first stopper 13 is provided at a position corresponding to an end of the gasket P in one end portion (first delivery position FP side) of the housing 11 so as not to interfere with a first suction holding portion 21 of the insertion mechanism portion 20 described later. Thus, even if the gasket P stacked in the housing 11 is pressed toward the one end side by the gasket sending-out portion 12, the gasket P is allowed to stay at the first delivery position FP by the first stopper 13.

As can be seen from fig. 3 and the like, the first stopper 13 is provided on the end portion side of the pad P in the direction (Y direction) in which the housing mechanism 10 and the insertion mechanism 20 are aligned, and therefore, prevents the movement of the first suction holding portion 21 from being hindered.

The material of the first stopper 13 is not particularly limited, and various known materials such as resin and metal may be used.

The second stopper 14 is indirectly shown in fig. 3 to 5 (since the second stopper 14 is provided inside the main body frame 24, in these figures, the main body frame 24 is viewed in the arrow direction for convenience), and is provided in the main body frame 24 described later, and has a function of defining a rotation stop position of the first suction holding portion 21. That is, as will be described later, since the first suction holding portion 21 of the present embodiment is rotationally moved (swiveled) by the moving arm 22, the stopped position after the swiveling of the first suction holding portion 21 is defined by the second stopper 14 in the main body frame 24. In other words, the first suction holding portion 21 is stopped by the second stopper 14 in the main body frame 24 while being restricted from rotational movement, and thus can be accurately positioned at the same height (position in the Z direction) as the first delivery position FP.

Next, a detailed structure of the insertion mechanism 20 in the present embodiment will be described.

The insertion mechanism 20 has a first suction holding portion 21 for sucking the pad P positioned at the first delivery position FP, and has a function of moving the pad P from the first delivery position FP to a second delivery position SP for placing the pad P on the object 1.

More specifically, the insertion mechanism section 20 of the present embodiment is configured to include a moving arm 22, an approaching/rotating mechanism 23a, a main body frame 24, and a suction mechanism 25 in addition to the first suction holding section 21 described above.

The first suction holding portion 21 is attached to a tip end portion of a moving arm 22 described later, and has a function of gripping the pad P. In the present embodiment, the first suction holding portion 21 is configured to suction-hold the pad P via a suction mechanism 25 described later.

As is apparent from fig. 3, the first suction holding portion 21 grips the peripheral edge of the gasket P at a portion (both end sides in the Z direction) other than the portion gripped by the first stopper 13 so as not to interfere with the rotational movement of the first suction holding portion 21.

One end of the moving arm 22 is fixed to an approaching/rotating mechanism 23a described later, and the other end is fixed to the first suction holding portion 21 described above. Therefore, when the moving arm 22 is rotated by the approaching/rotating mechanism 23a, the first suction holding portion 21 located at the tip end thereof can also be rotated about the X axis about the rotation center C.

The approaching/rotating mechanism 23a has a function of performing an approaching operation of moving the first suction holding part 21 in the X direction toward the first delivery position FP after the first suction holding part 21 comes into contact with the first stopper 14 to determine the position (height) in the Z direction; and a rotation (swiveling) operation of moving the first suction holding portion 21 toward the second delivery position SP after the first suction holding portion 21 suctions and holds the pad P.

In other words, the insertion mechanism section 20 (main body frame 24) in the present embodiment has the second stopper 14 that defines the rotation limit of the first suction holding section 21. The first suction holding portion 21 is stopped at a predetermined position by the second stopper 14 in the main body frame 24, and then moved in the X direction toward the first delivery position FP of the housing mechanism 10 to suck the pad P.

Specific mechanisms of the approach/rotation mechanism 23a are not particularly limited, and examples thereof include a rotation actuator mounted with a known cylinder mechanism or the like.

The main body frame 24 is mounted on an apparatus frame 40 described later, and has a function of mounting the first suction holding portion 21, the approach/rotation mechanism 23a, and the like described above. The material of the main body frame 24 is not particularly limited, and known materials such as resin and metal can be used as the material of other members.

As shown in fig. 1 and 3, in the present embodiment, the main body frame 24 is provided to the apparatus frame 40 such that the insertion mechanism portion 20 is interposed between the housing mechanism portion 10 and the holding mechanism portion 30.

The suction mechanism 25 is connected to a pump or the like, not shown, and provides a suction function to the first suction holding portion 21 via the pump. Therefore, one or more suction holes are formed in the first suction holding portion 21 of the present embodiment in the region facing the pad P, and the suction holding is realized by connecting the suction holes to the suction mechanism 25.

Next, a detailed structure of the holding mechanism 30 in the present embodiment will be described.

The holding mechanism 30 has the following functions: the spacer moved to the second delivery position is held by the insertion mechanism 20 until the binding object 1 is bound by the binding band B to form the binding joint BJ.

Here, the "first delivery position FP" in the present embodiment is a position at which the first suction holding portion 21 sucks and holds the pad P whose position is defined by the first stopper 13. On the other hand, the "second delivery position SP" in the present embodiment can be said to be a position at which the second suction-holding portion 31 of the holding mechanism portion 30 sucks and holds the pad P.

As described above, the insertion mechanism 20 rotates (rotates) the first suction holding part 21 around the center (rotation center C) between the housing mechanism 10 and the holding mechanism 30, thereby moving the first suction holding part 21 between the first delivery position FP and the second delivery position SP.

More specifically, the holding mechanism 30 of the present embodiment includes a second suction holding portion 31, a suction mechanism 32, a strap passing recess 33, and a main body frame 34.

The second suction holding portion 31 is provided in a main body frame 34 described later, and is fixedly disposed in the main body frame 34 in the present embodiment. The second suction-holding portion 31 has a function of sucking the pad P moved to the second delivery position SP via a suction mechanism 32 described later.

As will be described later, in the present embodiment, the pad P is transferred from the first suction holding portion 21 to the second suction holding portion 31. More specifically, at the second delivery position SP, the second suction holding portion 31 sucks the pad P, and then the suction of the pad P by the first suction holding portion 21 is released. In other words, the state shifts from "the first suction-holding portion 21 sucks the gasket P" to "the state where both the first suction-holding portion 21 and the second suction-holding portion 31 suck the gasket P", and then to "the state where the second suction-holding portion 31 sucks the gasket P".

The suction mechanism 32 is connected to a pump or the like, not shown, in the same manner as the suction mechanism 25, and provides a suction function to the second suction holding portion 31 via the pump. In the present embodiment, the main body frame 34 is provided with two second suction holding portions 31, which are connected to the suction mechanism 32 to perform suction holding.

In the present embodiment, two second suction holding portions 31 are provided to the main body frame 34, but the second suction holding portions 31 may be a plurality of three or more, or the second suction holding portion 31 may be a single one.

The tape passing recess 33 is a portion for ensuring a space for allowing the tape B to pass through the recess in a state where the second suction holding portion 31 has attracted the pad P. This allows the object 1 to be bound with the binding band B while interposing the gasket P therebetween while passing the binding band B through the inside of the binding band passing recess 33.

The main body frame 34 is mounted on an apparatus frame 40 described later, and has a function of mounting the second suction holding portion 31, the suction mechanism 32, and the like described above. The material of the main body frame 34 is not particularly limited, and for example, a known material such as resin or metal can be exemplified.

The apparatus frame 40 is a framework on which the housing mechanism 10, the insertion mechanism 20, and the holding mechanism 30 are mounted. The material of the apparatus frame 40 is not particularly limited, but various metal materials such as steel are preferable because a heavy object is mounted thereon.

The control device 50 includes a CPU or the like that executes a binding method of a binding tape described later, and collectively controls the housing mechanism unit 10, the insertion mechanism unit 20, and the holding mechanism unit 30 under the control of the control device 50.

As the control device 50, for example, a computer provided with a known arithmetic device, a memory, and the like can be exemplified. The control device 50 may be equipped with a known communication device and may be connected to an external network (such as the internet) by wire or wireless connection to enable remote operation.

[ binding System ]

The binding system of the present embodiment includes the above-described spacer insertion device 100 and a known band binding mechanism. The tape binding mechanism is not particularly limited as long as it has a function of binding a binding tape, and examples of the device disclosed in japanese patent application laid-open nos. 2009, 298476, 2001, 301712, and the like may be applied.

The strap binding mechanism has a function of binding the objects 1 with the binding strap B, in particular, in a state where the gasket P is interposed between the binding joint portion and the objects 1 by the gasket insertion device 100.

According to such a binding system, the object 1 can be bound with the binding band B while suppressing damage to the surface of the object 1.

[ binding method of binding tape ]

Next, a method of binding a binding band according to the present embodiment will be described with reference to fig. 2 to 6 as appropriate. In this binding method, since the binding band B is bound to the object 1 with the above-described spacer P interposed therebetween, damage to the object 1 by the binding band B and the like can be suppressed.

First, in step S101, as illustrated in fig. 1, the object 1 to be bundled is placed in the vicinity of the housing mechanism 10 housing the gasket P (i.e., in the vicinity of the gasket insertion apparatus 100).

Next, in step S102, the pad P sent out to the first delivery position FP by the housing mechanism unit 10 is sucked by the first suction holding unit 21 of the insertion mechanism unit 20.

Referring to fig. 4, the state transition of the spacer inserting apparatus 100 in step S102 will be described in more detail.

That is, as shown in fig. 4, in step S102, first, the approaching/rotating mechanism 23a rotates the moving arm 22 to a position where the rotational movement of the moving arm 22 is restricted by the second stopper 14. Next, as indicated by the number "1" and the arrow in fig. 4, after the height in the Z direction is determined, the approaching/rotating mechanism 23a moves the first suction holding part 21 together with the moving arm 22 toward the first delivery position FP.

At this time, as shown in fig. 4, the position of the pad P1 positioned at the lowermost position among the plurality of pads P stacked in the housing 11 is maintained by the first stopper 13.

After the first suction holding portion 21 moves in the X direction and comes into contact with the pad P1, the control device 50 performs control to suction-hold the pad P1 by the first suction holding portion 21 via the suction mechanism 25.

Then, in step S103, the control device 50 determines whether or not the suction of the pad P1 by the first suction holding portion 21 is completed. More specifically, the controller 50 monitors the value of the negative pressure indicated by the suction mechanism 25, and determines that the pad P1 is adsorbed on the first suction holding portion 21 when the value falls within a predetermined range.

Next, in step S104, the sucked pad P1 is moved from the first delivery position FP to the second delivery position SP at which the pad P1 is placed on the object 1.

That is, as indicated by the number "2" and the arrow in fig. 4, the approaching/rotating mechanism 23a moves the first suction holding portion 21 from the first delivery position FP toward the second delivery position SP together with the moving arm 22.

Next, in step S105, the control device 50 determines whether or not the circling movement of the pad P1 has reached a predetermined position.

The predetermined position is a position at which at least a part of the pad P1 faces the second suction-holding portion 31. Thus, the second suction-holding portion 31 can suction-hold the pad P1 by the pad P1 being relatively close to the second suction-holding portion 31.

That is, in the next step S106, the delivery from the insertion mechanism portion 20 to the pad P1 of the holding mechanism portion 30 is performed. More specifically, as indicated by the number "3" and the arrow in fig. 5, the approaching/rotating mechanism 23a first moves the first suction holding portion 21 in the X-axis direction toward the second delivery position SP together with the moving arm 22. Thereby, the gasket P1 held by the first suction holding portion 21 comes into contact with the second suction holding portion 31. At this time, the controller 50 starts suction of the pad P1 by the second suction holding portion 31 via the suction mechanism 32.

Therefore, in this state, the pad P1 is attracted to the first attraction and holding portion 21 on one surface and attracted to the second attraction and holding portion 31 on the other surface. In other words, the pad P1 is in a state of being sucked by both the first suction-holding portion 21 and the second suction-holding portion 31.

Then, after detecting the above state based on the negative pressure values of the suction mechanism 25 and the suction mechanism 32, the control device 50 operates the approaching/rotating mechanism 23a to separate the first suction holding portion 21 from the pad P1 together with the moving arm 22 as indicated by the arrow "4" in fig. 5.

By the above operation, the transfer from the insertion mechanism portion 20 to the pad P1 of the holding mechanism portion 30 is performed.

After the transfer of the pad P1 from the insertion mechanism section 20 to the holding mechanism section 30 is completed, the approaching/rotating mechanism 23a moves (rotates) the first suction holding section 21 together with the moving arm 22 toward the first transfer position FP in order to hold the next pad P2, as indicated by the reference numeral "5" and the arrow in fig. 5.

Then, in step S107, the spacer P1 moved to the second delivery position SP by the insertion mechanism unit 20 is held by the holding mechanism unit 30 so that the spacer P1 is interposed between the binding joint BJ generated when the binding band B is bound and the object 1 to be bound.

That is, as shown in fig. 5, the pad P1 is held by the holding mechanism 30, and thereafter, the holding mechanism 30 is brought close to the object 1 to be bundled, so that the object 1 can be bundled with the bundling band B.

In the present embodiment, as shown in fig. 1(b), a part of the apparatus frame 40 is rotated to rotate a part of the pad inserting apparatus 100 (in the present embodiment, the inserting mechanism unit 20 and the holding mechanism unit 30), thereby performing control to bring the pad P1 close to the object 1 so that the pad P1 is interposed between the binding joint BJ and the object 1.

Next, in step S108, the object 1 is bound with the binding band B via the pad P1 held in step S107. More specifically, the objects 1 are bound with the binding band B using the known binding apparatus described above. Thereby, for example, as illustrated in fig. 6, the object 1 is bound with the binding band B via the spacer P.

At this time, since the binding joint BJ does not directly contact the surface of the object 1, and the pad P also functions as a buffer member, damage to the surface of the object 1 and the like can be suppressed.

According to the method for binding a binding band of the present embodiment described above, the object 1 can be bound with a simple configuration while suppressing damage to the surface of the object 1.

[ second embodiment ]

[ spacer inserting device 200]

Next, a gasket insertion device 200 according to a second embodiment will be described with reference to fig. 7 to 16. The gasket insertion device 200 according to the second embodiment is mainly characterized in that the housing mechanism 10 includes the erection device 15, the insertion mechanism 20 linearly moves the first suction holding part 21, and the holding mechanism 30 includes the turning mechanism 35 and turns to move between the binding joint BJ and the object 1. Therefore, the same reference numerals are given to the components having the same functions as those of the first embodiment, and the description thereof will be omitted as appropriate.

As shown in fig. 7 and 8, the spacer inserting apparatus 200 according to the present embodiment further includes a standing apparatus 15.

The erecting device 15 has a function of erecting the pad P sent to the mounting surface 15a (erecting the pad P so that the main surface thereof is parallel to the suction surface of the first suction holding portion 21) and positioning the pad P at the first delivery position FP. The specific structure of the erection device 15 is not particularly limited, and for example, a known cylinder mechanism, a motor drive mechanism, or the like may be suitably used.

Next, the operation until the pad P disposed at the first delivery position FP is sucked by the first suction holding portion 21 will be described in detail with reference to fig. 9 to 12.

First, as shown in fig. 9 and 10, the pad feeding unit 12 is constituted by a cylinder mechanism and a plate-like member in the present embodiment. Then, by moving the plate-like member in the Y direction by the cylinder mechanism, the gasket P at the lowermost layer among the gaskets P stacked in the frame 11 can be fed out into the mounting surface 15a of the upright device 15 as in the so-called hit-and-rub (japanese: だるま No. とし). Therefore, the thickness of the plate-like member in the Z direction is set to be equal to or less than the thickness of the spacer P.

As is apparent from fig. 9, in the present embodiment, since a plurality of pads P are stacked in the vertical direction, the pressing member 14 is placed on the uppermost pad P in the housing 11. Thus, after the lowermost pad P is fed out, the next pad P is pushed down to the feedable position by the own weight of the pushing member 14 and the pad P.

As the pressing member 14, a known mechanism capable of generating a pressing force, such as a weight having a predetermined weight, a spring mechanism, or a cylinder mechanism, may be applied.

Next, as shown in fig. 11, the gasket P that has reached the mounting surface 15a of the standing device 15 by the gasket feeding portion 12 is raised by the standing device 15 so as to be in contact with the first suction holding portion 21 of the insertion mechanism portion 20 in an opposed manner. On the other hand, the controller 50 controls the plate-like member of the pad feeding unit 12 to return to the original position, thereby performing an operation for preparing for feeding the next pad P.

As shown in fig. 12, when the gasket P is brought into contact with the first suction holding portion 21 by the standing device 15, the control device 50 performs control for suction holding of the gasket P by the first suction holding portion 21 via the suction mechanism 25.

As shown in the drawing, after the first suction holding portion 21 suctions and holds the pad P, the control device 50 controls the erecting device 15 to return to the original position, thereby performing an operation for preparing for erecting the next pad P.

[ binding method of binding tape ]

Hereinafter, the method of binding a binding band in the present embodiment will be described mainly focusing on differences from the first embodiment with reference to fig. 2 and 13 to 16.

In general, the insertion mechanism portion 20 in the present embodiment also has features. The holding mechanism 30 holds the pad P positioned at the second delivery position SP, and moves the held pad P to contact the side of the object 1.

In general, the method for binding a binding tape according to the present embodiment has features in the following respects:

(1) the first suction holding part 21 sucks the pad P after the pad fed from the housing mechanism 10 is raised by the raising device 15;

(2) while the first suction holding portion 21 is sucking the pad P, the first suction holding portion 21 is linearly moved from the first delivery position FP to the second delivery position SP;

(3) the holding mechanism 30 holds the pad P positioned at the second delivery position SP, and moves the held pad P via the swiveling mechanism 35 so as to contact the side of the object 1 to be bundled.

First, as in step S101 described in the first embodiment, the object 1 to be bundled is placed near the spacer inserting apparatus 200.

Next, in step S102, as described above with reference to fig. 9 to 12, the pad P1 sent to the first delivery position FP is sucked and held by the first suction-holding portion 21 of the insertion mechanism portion 20.

Then, in step S103, the control device 50 determines whether or not the suction of the pad P1 by the first suction holding portion 21 is completed, as in the first embodiment.

In the next step S104, the sucked pad P1 is moved from the first delivery position FP to the second delivery position SP at which the pad P1 is placed on the bundle object 1.

That is, as indicated by the number "1" and the arrow in fig. 13, the linear movement mechanism 23b first moves the first suction holding portion 21 in the-X direction together with the movement arm 22 until it becomes linearly movable.

Next, the linear movement mechanism 23c linearly moves the first suction holding portion 21 in the Y direction together with the movement arm 22. Thereby, the pad P1 held by the first suction holding portion 21 faces the second suction holding portion 32.

Then, the linear movement mechanism 23b again moves the first suction holding portion 21 in the X direction together with the movement arm 22, and the pad P1 comes into contact with the second suction holding portion 32.

Next, in step S105, the control device 50 determines whether or not the spacer P1 that has been rotated has reached a predetermined position. The predetermined position is a position at which at least a part of the pad P1 faces the second suction-holding portion 31.

Then, in the next step S106, the transfer from the insertion mechanism portion 20 to the pad P1 of the holding mechanism portion 30 is performed. More specifically, the controller 50 first starts suction of the pad P1 by the second suction holding portion 31 via the suction mechanism 32. Next, the control device 50 detects the suction state based on the negative pressure values of the suction mechanism 25 and the suction mechanism 32, and then performs an operation of releasing the suction of the first suction holding portion 21 to the pad P1.

After the transfer of the pad P1 from the insertion mechanism section 20 to the holding mechanism section 30 is completed, the linear movement mechanisms 23b and 23c linearly move the first suction holding section 21 together with the movement arm 22 toward the first transfer position FP in order to hold the next pad P2, as indicated by the numbers "4" and "5" and the arrow in fig. 15.

Thereafter, in step S107, similarly to the first embodiment described above, control is performed to bring the pad P1 close to the object 1 so that the pad P1 is interposed between the binding joint BJ and the object 1.

More specifically, as shown in fig. 16, a part of the device frame 40 is turned while the spacer P1 is held by the holding mechanism 30, so that a part of the spacer insertion device 200 (in this example, the holding mechanism 30) is turned, and the spacer P1 approaches the object 1 to be bundled.

Then, in step 109, as in the first embodiment, the object 1 is bound with the binding band B via the spacer P1 held in step S107.

According to the spacer inserting apparatus 200 and the binding system of the second embodiment described above, the objects 1 can be bound with a simple configuration while suppressing damage to the surfaces of the objects 1.

The above-described embodiments are merely examples, and a new gasket insertion apparatus and bundling system may be configured by appropriately combining the respective elements of the embodiments without departing from the scope of the present application.

For example, the number and arrangement position of the first suction holding portions 21 and the second suction holding portions 31 may be adjusted as appropriate.

Industrial applicability

As described above, the gasket insertion device and the binding system according to the present invention are suitable for constructing an apparatus system that can realize miniaturization of the device and prevention of damage to the surface of the bound object with a simple configuration.
