The heating and bonding apparatus 100 according to the present embodiment relates to a bonding apparatus for thermally bonding objects to each other. For example, the heating and bonding apparatus 100 according to the present embodiment can be used when bonding a plastic handle to an outer wrapper for a base, which is one of poly bags.

1 to 3, the heating and joining apparatus 100 according to the present embodiment includes a joining part 60 for joining an object and a driving part 10 for moving the heating plates 61 and 62 to be described later of the joining part 60 ).

First, the joining portion 60 will be described. The bonding portion 60 includes a first heating plate 61 and a second heating plate 62 facing the first heating plate 61, as shown in FIGS. The joining portion 60 thermally bonds an object placed between the heating plates 61 and 62 by the pressing by the heating plates 61 and 62. The heating plates 61 and 62 may be moved by a driving unit 10 to be contacted with each other or separated from each other. For example, while the heating plates 61 and 62 are spaced apart from each other, the object may be supplied in a direction to pierce the ground with reference to Fig. 2, and the heating plates 61 and 62 may contact each other So that the object can be bonded.

3, the first heating plate 61 includes an upper member 64 disposed at the upper end, a first heating plate 65 provided at the lower side of the upper member 64, And an elastic member 66 which is made of a metal. The upper member 64 may be connected to a first shaft 51 to be described later. The first heating plate 65 is in contact with the second heating plate 62 to generate heat. That is, while the first heat plate 65 is in contact with the second heat plate 62, the object can be bonded to the heat by the first heat plate 65. The first heating plate 65 may include a heating coil or the like for generating heat. The first heat plate 65 may be configured to generate heat directly, or it may be configured to transfer the heat generated therein to the object.

The elastic member 66 applies an elastic force between the upper member 64 and the first heat plate 65. The first heat plate 65 can be resiliently moved toward the top member 64 by the elastic member 66 when the heating plates 61 and 62 contact each other for bonding the object. With the above movement, the impact generated when the heating plates 61 and 62 are in contact can be mitigated. In addition, despite the movement of the first axis 51 and the second axis 52 to be described later, since the contact of the heating plates 61 and 62 can be maintained for a predetermined time by the above movement, heat is uniformly transmitted . This will be described later.

For reference, the first heating plate 61 may further include a separate structure as shown in FIG. 3 for the elastic movement of the first heating plate 65. The second heating plate 62 may also be configured as the first heating plate 61. However, the second heating plate 62 may not generate heat regardless of the name of the heating plate. That is, the second heating plate 62 may perform only a function of simply pressing the object together with the first heating plate 61.

Next, the driving unit 10 will be described. The driving unit 10 moves the heating plates 61 and 62 in contact with each other or away from each other. To this end, the driving unit 10 includes a first axis 51, a second axis 52, and a switching bar 70.

The first shaft 51 moves up and down to move the first heating plate 61 up and down. For example, when the first shaft 51 moves downward, the first heating plate 61 can also move downward as the first shaft 51 moves. To this end, the first shaft 51 is directly or indirectly connected to the first heating plate 61. That is, the first shaft 51 may be directly connected to the first heating plate 61, or may be connected to the first heating plate 61 via a separate structure.

The second shaft 52 moves up and down to move the second heating plate 62 up and down via a switching bar 70 to be described later. The second shaft 52 moves up and down in the same manner as the first shaft 51 moves up and down. For example, when the first axis 51 moves downward, the second axis 52 can also move downward.

The switching bar 70 moves the second heating plate 62 up and down. For this purpose, the switching bar 70 is directly or indirectly connected to the second heating plate 62. That is, the switching bar 70 may be directly connected to the second heating plate 62, or may be connected to the second heating plate 62 via a separate configuration as shown in FIG.

The switching bar 70 moves the second heating plate 62 up and down by the second shaft 52 opposite to the upward and downward movement of the first shaft 51. [ For example, when the first shaft 51 moves downward, the switching bar 70 can move the second heating plate 62 upward. That is, when the first shaft 51 moves downward, the second shaft 52 also moves downward, and the diverting bar 70 moves the downward movement of the second shaft 52 toward the upper side of the second heating plate 62 Switch to movement. Accordingly, the first heating plate 61 and the second heating plate 62 can be moved in contact with each other or with each other.

The switching bar 70 is directly or indirectly connected to the second shaft 52 at one end and directly or indirectly connected to the second heating plate 62 at the other end for the above switching, The second shaft 52 can rotate about the rotation axis 71 provided between the first shaft 52 and the second shaft 52. [ 3, when the second shaft 52 connected to one end of the switching bar 70 moves downward, the switching bar 70 can rotate counterclockwise around the rotating shaft 71 And the second heating plate 62 connected to the other end of the switching bar 70 by the rotation can move upward. 3 is connected to the second heating plate 62 through another connecting bar at the other end.

The heating and bonding apparatus 100 according to the present embodiment can move the heating plates 61 and 62 through the first shaft 51, the second shaft 52 and the switching bar 70 as described above. As described above, the heating and bonding apparatus 100 according to the present embodiment can realize the movement of the heating plates 61 and 62 by a very simple structure. The heating and joining apparatus 100 according to the present embodiment is configured such that even if the first and second shafts 51 and 52 move in the same direction, the first and second heating plates 62 are different from each other It is possible to greatly simplify the driving structure of the first and second shafts 51 and 52 as compared with moving the first and second shafts 51 and 52 in different directions from the beginning.

The heating and joining apparatus 100 according to the present embodiment may further include a servo motor for generating a driving force for moving the first and second shafts 51 and 52 up and down. Since the servomotor can easily control the rotation of the motor shaft, if the servomotor is employed, the movement of the axes 51 and 52 necessary for the movement of the heating plates 61 and 62 can be easily controlled . The role of the servo motor may be the same as that of the drive motor 11 of the drive unit 10 to be described later.

The heating and joining apparatus 100 according to the present embodiment includes a driving motor 11 and a transmitting unit 20 that receives driving force from the driving motor 11 and moves the first and second shafts 51 and 52 up and down, As shown in FIG. The driving motor 11 may employ a normal motor for generating rotational force. The rotational force (driving force) generated in the driving motor 11 can be switched to the driving force required for the up and down movement of the axes 51 and 52 by the transmitting portion 20. [ More specifically, the transmitting portion 20 may include a rotating body 21, a driving shaft 22, a first connecting body 40, and a second connecting body 41.

The rotating body 21 receives the driving force from the driving motor 11 and rotates. To this end, the rotating body 21 may be connected to the driving motor 11 through a belt or a chain (not shown).

The rotating body 21 can rotate about the center line shown in Fig. For this rotation, the heating and bonding apparatus 100 according to the present embodiment may further include a body portion 80. [

The body portion 80 is provided at one side of the upper plate 81 and at least one portion of the upper plate 81 on which the rotating body 21 is rotatable (Not shown). In this embodiment, two fixing portions 30 are exemplified. Since the two fixing portions 30 are disposed apart from each other, the plurality of fixing portions 30 can stably support the rotating body 21. [ Since the plurality of fixing portions 30 rotatably support the rotating body 21, the rotating body 21 can rotate around the center line of FIG. 4, each of the fixing portions 30 is provided with a second guide hole 32 into which the rotating body 21 is inserted and a second guide hole 32 provided in the second guide hole 32, And a second bearing (33) for rotatably supporting the first bearing (21).

The driving shaft 22 is eccentrically connected to the rotating body 21. That is, as shown in FIG. 5, the center of the drive shaft 22 is spaced apart from the center of the rotating body 21 by a predetermined distance. When the rotating body 21 rotates due to such eccentricity, the drive shaft 22 can move to a circular track. 6, when the rotary body 21 rotates while being supported by the fixed portion 30, the drive shaft 22 is rotated about the center line of FIG. 5 due to the eccentricity described above, ). &Lt; / RTI >

For reference, the driving shaft 22 may be integrally formed with the rotating body 21, or may be formed separately and then coupled to the rotating body 21. Further, two drive shafts 22 formed separately may be coupled to the same position on both sides of the rotating body 21, respectively.

The first connecting body 40 and the second connecting body 41 are connected to both ends of the driving shaft 22, respectively. At this time, the drive shaft 22 is rotatable by the first and second link members 40 and 41. For example, when the drive shaft 22 moves from the 6 o'clock position to the 3 o'clock position of the rotating body 21 on the basis of Fig. 6, one point of the drive shaft 22 at 6 o'clock position is also shifted from the 6 o'clock position to the 3 o'clock position . In other words, the drive shaft 22 also rotates itself about itself. At this time, if the connecting members 40 and 41 are fixed to the driving shaft 22, the connecting members 40 and 41 will also rotate according to the self-rotation of the driving shaft 22. If such rotation occurs, the connection between the shaft (51, 52) connected to the connector and the heating plate (or the switching bar) will not be maintained. In order to prevent this, the drive shaft 22 is rotatably connected to the connecting body in this embodiment.

As shown in FIG. 4, each of the link members 40 and 41 is provided with a first guide hole 42 into which the drive shaft 22 is inserted and a second guide hole 42 through which the drive shaft 22) for rotatably supporting the first bearing (43). Due to this structure, the driving shaft 22 can be rotatably connected to the connecting body, and the connecting body may not rotate even if the driving shaft 22 rotates.

5, the drive shaft 22 eccentrically connected to the rotating body 21 is moved along the circular orbit C of FIG. 6 around the center line of FIG. 5 At this time, even if the driving shaft 22 rotates itself, the connecting bodies 40 and 41 connected to the driving shaft 22 may not rotate. Since the link members 40 and 41 are connected to the drive shaft 22, they can move together with the drive shaft 22 along the circular orbit C of FIG. Since the first and second shafts 51 and 52 are connected to the first connection member 40 and the second connection member 41 respectively and thus the first and second shafts 51 and 52 can move up and down according to the movement of the connection members 40 and 41 have. At this time, since both ends of the drive shaft 22 move in the same orbit, the first and second shafts 51 and 52 can also move in the same direction. That is, when the first shaft 51 moves upward, the second shaft 52 can also move upward.

Consequently, in the present embodiment, the transmitting portion 20 can switch the rotation of the rotating body 21 by the drive motor 11 to the up-and-down movement of the first and second shafts 51 and 52. 3, the lower ends of the first and second shafts 51 and 52 may be rotatably connected to the first heating plate 61 or the switching bar 70 to implement the above switching.

Since the heating and bonding apparatus 100 according to the present embodiment includes the transfer unit 20 as described above, it is possible to realize the movement of the heating plates 61 and 62 in different directions by only one driving motor 11. Further, since the drive motor 11 can be generally controlled very precisely, the movement of the heating plates 61 and 62 can be controlled very accurately by controlling only one drive motor 11. [ Accordingly, the heating and bonding apparatus 100 according to the present embodiment can repeatedly bond successively supplied objects with high reliability.

4, the first and second connecting members 40 and 41 are provided at both ends of the driving shaft 22 so that the first and second connecting members 40 and 41 are separated from the driving shaft 22. In other words, And a fixing pin 48 for fixing the cover portion 49 to the drive shaft 22. The cover portion 49 may be formed of a metal such as aluminum, The jaws formed inside the coupling members 40 and 41 are caught by the cover portion 49 so that the coupling members 40 and 41 may not be separated from the driving shaft 22 during movement of the driving shaft 22. [

1 and 2, the body portion 80 on which the driving portion 10 is installed in the present embodiment includes a lower plate 82 spaced downward from the upper plate 81, And a cylinder 83 for selectively moving the upper plate 81 upwardly away from the lower plate 82. The upper plate 81 may be provided with a drive motor 11 and a transfer unit 20. When the upper plate 81 is moved upward by the cylinder 83, With the upward movement of the second link members 40, 41, the first and second shafts 51, 52 connected to them can also be moved upward. With this movement, the first and second heating plates 62 can be separated from each other.

In this embodiment, the cylinder 83 can be operated when the drive motor 11 is stopped. The heating and bonding apparatus 100 bonds the object by heat. Accordingly, if the heating plates 61 and 62 are in contact with each other when the drive motor 11 is stopped by the user or by accident, heat may be applied to the object more than necessary, thereby causing defects on the surface of the object In addition, fire may occur. The movement of the shafts 51 and 52 due to the movement of the upper plate 81 causes the heating plates (not shown) to move by the movement of the upper plate 81 when the cylinder 83 is automatically operated when the drive motor 11 stops, 61, and 62 may be spaced apart from each other, and the above problems may not occur. For reference, when the drive motor 11 is temporarily stopped for supply of the object, it can be processed differently from the above stop.

The heating and bonding apparatus 100 according to the present embodiment includes a supporting portion 85 provided at a lower portion of the body portion 80 in addition to the body portion 80 where the driving portion 10 is installed and supporting the body portion 80, As shown in FIG. At this time, the body portion 80 is supported by the support portion 85 so as to be reciprocally movable in a direction perpendicular to the direction in which the object is supplied to the joint portion 60 (the direction of piercing the ground surface with reference to Fig. 2) As shown in FIG. The joint portion 60 connected to the transmitting portion 20 of the driving portion 10 can be moved along with the movement of the body portion 80. Therefore, And the contact position of the object can be easily adjusted.

To this end, the support portion 85 may include a handle 90 and a guide bar 91 that is rotated by the rotation of the handle 90. A thread may be formed on the guide rod 91 and a thread may be formed on the support plate 84 of the body portion 80 so as to engage with the thread of the guide rod 91. Accordingly, when the user turns the knob 90, the whole body portion 80 can be moved by the support plate 84 by the rotation of the guide rod 91. [ The support plate 84 is provided below the lower plate 82 as one body of the body portion 80 and supports the body portion 80 at an upper portion of the support portion 85. [ The support plate 84 may have a plurality of rollers 93 that abut the support 85 for movement as described above.

The operation of the heating and bonding apparatus 100 according to the present embodiment will be described. When the driving motor 11 is operated, the rotating body 21 receives the driving force (rotational force) from the driving motor 11 through the belt (or chain) and rotates. At this time, the rotating body 21 is rotatably supported by the fixing portion 30 and rotates about the center line of FIG. When the rotating body 21 rotates, the driving shaft 22 eccentrically connected to the rotating body 21 can move along the circular orbit C of FIG. 6 around the center line of FIG. Since the link members 40 and 41 are connected to the drive shaft 22, they can move together with the drive shaft 22 along the circular orbit C in Fig. Since the first and second shafts 51 and 52 are connected to the first link member 40 and the second link member 41 respectively, Can be moved. By the movement of the first and second shafts 51 and 52, the heating plates 61 and 62 can move in contact with each other or with each other.

However, the first heating plate 65 of the first heating plate 61 can elastically move toward the upper member 64 by the elastic member 66. Therefore, in the present embodiment, the heating plates 61 and 62 can be configured to be in contact with each other before the first and second shafts 51 and 52 reach the lowest position with reference to Fig. For example, when the first and second shafts 51 and 52 move from the uppermost side to the lowermost side by A cm, when the axes 51 and 52 move downward by (A-1) cm from the uppermost side The heating plates 61 and 62 may be in contact with each other.

Even if constructed in this manner, the movement of a certain distance can be accommodated by the movement of the first heat plate 65. [ Even if the rotating body 21 rotates at a constant angular velocity by the drive motor 11, the contact time of the heating plates 61 and 62 can be maintained for a predetermined period of time, . That is, during the rotation of the rotating body 21 from the time when the axes 51 and 52 move downward by (A-1) cm from the uppermost position to the time when they move upward by 1 cm from the lowermost position, The heating plates 61 and 62 will be in contact with each other.

Thus, the heating and bonding apparatus 100 according to the present embodiment can control the driving motor 11 very simply. For example, if the rotating body 21 is rotated by one rotation by the driving motor 11, the heating plates 61 and 62 can press and bond the object for a predetermined time during the rotation. If the driving motor 11 is stopped for a predetermined time after the rotation, the next object may be supplied again to the joining portion 60 while the heating plates 61 and 62 are spaced apart from each other.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
