Description

The present invention relates to a horizontal filling and packaging machine, and more particularly to a horizontal filling and packaging machine equipped with a replaceable former.

A horizontal bag-making filling and packaging machine (hereinafter, also simply referred to as a “packaging machine”) uses a former (this is a “cylinder” or “manufacturing”) a band-shaped packaging material unwound from a roll to wrap an object to be packaged. It is known to produce a bag package by molding it into a tubular shape with a bag (also called a bag), feeding the product into this tubular packaging material after center sealing, and finally performing end sealing and cutting. ..

Here, the packaged product includes a single product and an collective product (for example, a stack of individual products), and the dimensions such as the width and height of the single product, the width and height of the entire collective product, etc. The dimensions of are also various in size. In order to deal with such various sizes of products to be packaged, the former is prepared in advance with a plurality of types of formers having different dimensions of a tubular package that can be formed, and each time the product to be packaged is switched, the former is supported. The worker selects a possible former and replaces it.

In addition to this, there is also a dimensionally variable former in which the dimensions of the portion that guides the strip-shaped packaging material can be adjusted and it is possible to form a tubular wrapping body having various dimensions. Such a former does not need to be replaced based on a change in the dimensions of the product or the like, but there is an opportunity to remove the former for maintenance or cleaning of the former itself, and the worker also performs this replacement.
Prior art for these formers is disclosed in Patent Documents 1 and 2.

An example of such a replaceable former and a mechanism for connecting the former to the main body of the packaging machine will be described with reference to FIG.

The former 100 of FIG. 6 has a former main body 101 having a side plate, a bottom plate, and the like for forming a strip-shaped packaging material Fw to be fed into a tubular packaging material Ft, a base 102 formed on the upper portion of the former main body 101, and a base 102. It is configured to include a vertical arm 103 protruding upward from the. Of these, a penetrating elongated groove 104 formed along the longitudinal direction is formed in the upper end side region of the vertical arm 103 so that the mounting bolt 105 can be inserted.

On the other hand, from the main body wall 120 of the packaging machine main body, a horizontal arm 111 for attaching the vertical arm 103 of the former 100 extends horizontally toward the upper side of the former 100. A connecting block 112 for connecting the vertical arm 103 is connected to the tip of the horizontal arm 111, and a hole (not shown) for screwing a mounting bolt 105 with a gripping knob is prepared. ing.
The upper end of the vertical arm 103 is formed with a bent portion 106 that is bent in an L shape toward the main body of the packaging machine. An adjusting screw 107 is inserted and screwed into the bent portion 106 in order to adjust the height with respect to the connecting block 112, and protrudes downward.

Therefore, the operator who replaces the former passes the mounting bolt 105 through the through elongated groove 104 while holding the former 100 at the installation position, and further inserts the mounting bolt 105 into the fixing screw hole of the connecting block 112. Screw in. As a result, the former is placed at a preset installation position (center position) by contacting the mounting surface of the vertical arm 103 with the mounting surface of the connecting block 112 and contacting the adjusting screw 107 with the upper surface of the connecting block 112. It can be installed in the installation direction and installation height.

However, the technique shown in FIG. 6 is insufficient in tightening because when the former 100 is fixed to the main body wall 112 of the machine body, the mounting bolts and the like 105 are manually tightened and fixed. Then, there is a risk that the center position may be displaced or the posture of the former may be tilted with respect to the transport direction.

On the other hand, there are many women, the elderly, and people with disabilities who have weak grip strength, and when using conventional packaging machines, it is a physical burden for these people to try to fix the former securely. There was a big inconvenience, such as having to get the help of another strong person in some cases. In addition, it could be an obstacle to the promotion of employment in the modern society aiming to promote employment of these women, the elderly, and persons with disabilities.

Also, even for those with strong force, it is necessary to tighten with a certain force or more in order to securely fix the former, but since the strength of this tightening force depends on subjective judgment, tightening The machine could not guarantee the reliable mounting by tightening with a certain force or more because the tightening force varies from person to person and the tightening force varies depending on the physical condition etc. for each tightening opportunity.

[Purpose of Invention]
The present invention has been made to improve these inconveniences, and an object thereof relies on the magnitude of the force of the operator and subjective judgment when fixing the replaceable former in a predetermined installation position. It is an object of the present invention to provide a packaging machine capable of securely fixing a former.

In order to achieve the above object, the horizontal bag-making filling and packaging machine according to the present invention is made of a horizontal type including a machine main body and a former for forming a strip-shaped packaging material supplied from a packaging material supply source into a tubular shape. A machine body that is a bag filling and packaging machine and is provided on the machine body side and is detachably connected to a part of the former so as to hold the former at a predetermined installation position on the path of the packaging material. A side connecting means, a movement regulating means capable of advancing / retreating to a movement restricting position for restricting the movement of a part of the connected former, a driving means for driving the moving regulating means, and an operation input from the outside, It is characterized by including a drive control means for controlling the drive operation of the drive means.

According to the horizontal bag-making filling / packaging machine of the present invention, since the above-described configuration is adopted, when the former is connected to the machine body, if there is an operation input from the outside, the former is connected to the former. Correspondingly, the drive means is driven via the drive control means, the drive means advances and retreats the movement restricting means with respect to the movement regulation position, and when the movement regulation means advances to the movement regulation position, the movement regulation means advances through the connection means. The movement of a part of the connected former is restricted, so that the former can be fixed to the installation position. On the other hand, when there is another operation input from the outside, the driving means is driven again in response to this, and when the movement restricting means retreats from the movement restricting position, one of the formers connected via the connecting means. The movement restriction of the part is lifted, and the former can be removed.
Therefore, when fixing the replaceable former to a predetermined installation position, the former can be reliably fixed without relying on the magnitude of the force of the operator or subjective judgment.

A support arm 27 that supports the support arm 27 and an arm support roller 26 that rotatably fixes the support arm 27 to the main body wall 11A are provided.

[Former]
Next, referring to FIGS. 2 (A) and 2 (B), the former 15 and the former-side connecting base 40 provided in the horizontal bag-making filling and packaging machine according to the first embodiment, and the machine A part of the main body 11, the machine main body side connecting portion 50, and the air cylinder device 60 will be described.
Note that FIGS. 2 (A) and 2 (B) are shown in a state in which the downstream support 52 described later is removed for the sake of clarity (the downstream support 52 is shown by a chain double-dashed line). There is).

As for the former 15, various conventionally known interchangeable formers can be adopted in the present invention. In the first embodiment, the formers of the types shown in FIGS. 1 and 2 are mounted.

The former 15 is used to install the former main body 30 and the former main body 30 at a predetermined installation position on the path of the strip-shaped packaging material Fw (or to fix the former main body 30 to the packaging machine main body 11). It is composed of a former-side connecting portion 40 for connecting the main body 30 to the connecting portion 50 on the machine main body side.

First, the former main body 30 includes a pair of former former side plates 31, 31 and a former main body base 34 that supports the pair of former former side plates 31, 31 at a width interval substantially corresponding to the width dimension of the tubular packaging material Ft. In the rear region of the pair of former side plates, the pair of former bottom plates 32, 32 extending inward from the lower edges of the pair of former side plates 31, 31 and extending to opposite positions through the gap 33, and the pair. It is provided with a front end support portion 37 extending by the width interval in the front end region of the former side plate.

Further, the former body 30 includes an opening 36 surrounded by a front region edge portion of the pair of former former side plates 31 and 31, a front side edge portion of the pair of former former bottom plates 32 and 32, and a rear end of the front end support portion 37. ing.

In the above configuration, the strip-shaped packaging material Fw is introduced from the opening 36, and both side edges of the strip-shaped packaging material Fw are pulled out while being overlapped diagonally downward from the gap 33 (actually, this drawer is drawn to the center sealing device 17). (Performed by an annexed film pulling roller (not shown)), while the other parts of the strip wrapping material Fw are the inner surfaces of the pair of former side plates 31, 31 and the upper surfaces of the pair of former bottom plates 32, 32. It is formed in a tubular shape by the lower surface of the former body base 34. As a result, the tubular packaging material Ft as shown in FIG. 1 is formed after passing through the former.

Next, the installation position of the former 15 will be described. In order to form a clean tubular packaging material Ft, it is necessary to be placed at an installation position that satisfies the following conditions. First, when the former body 30 of the former 15 is used (see, for example, FIG. 2B), the transport direction of the tubular packaging material Ft after passing through the former body 30 and the direction of the gap 33 of the former body 30 coincide with each other. Must be arranged to do so. Further, it is necessary to install the former body 30 so that the position in the width direction of the gap 33 between the opposite ends of the pair of former bottom plates 32, 32 coincides with the center in the width direction of the tubular packaging material Ft. Further, it is necessary to arrange so that the position and orientation of the gap between the pair of heat sealers (not shown) of the center seal device 17 located downstream of the former 15 and the position and orientation of the gap 33 of the former main body 30 match. is there.

This also applies to the gaps between the pair of center seal plates 17A and 17A of the center seal device 17, as shown in FIG. 2 (B).

[Connecting means]
Next, the position and orientation in the width direction of the former body 30 in the first embodiment are positioned at predetermined installation positions for each type of former, and the former side connecting portion 40 and the machine body side for supporting at this position. The connection portion 50 and the like will be described.

First, the former side connecting portion 40 will be described. Referring to FIG. 2 again, the former side connecting portion 40 is provided in the central region of the surface of the former side plate 31 on the side of the machine main body 11 facing the main body wall 11A. The former side connecting portion 40 is substantially horizontally oriented toward the machine main body side from the side central region of the former main body 30 (for example, toward the main body wall 11A as in the first embodiment). It is configured as a protruding connecting member 41 that protrudes.

The end of the connecting projecting member 41 facing the former side plate 31 facing the machine body 11 is bolted to the end thereof, and the former side plate 31 is bolted to the side of the former machine body (to the machine body). It extends straight (towards). The connecting projecting member 41 is composed of a base end region 41A, a step portion 41B, and a tip region 41C from the side close to the former side plate 31, and is designed so that the height of the step portion 41B is low. There is.

Further, the upper surface of the connecting projecting member 41 is flat in both the proximal region 41A and the distal region 41C. On the other hand, on the lower surface of the connecting projecting member 41, a groove portion 41D having a semicircular cross section corresponding to the cross-sectional shape of the cylindrical lock member 62 (described later) is formed in the tip region 41C over the width direction.

However, this is an example and is not limited. If the lock member 62 is a prismatic column, a groove having a quadrangular cross section may be used, or the lower surface of the connecting projecting member 41 may be convex, and a recess corresponding to the lock member 62 may be provided.

Further, a runout that regulates the runout of the former body 30 from the center of both side surfaces of the base end region 41A of the connecting projecting member 41 toward the facing surfaces of the pair of upstream and downstream supports 51 and 52 described below. The regulatory protrusions 42, 42 are protruding. When the projecting members 42, 42 are inserted, both ends of the projecting members 42, 42 for runout regulation slide on the facing surfaces and come into contact with the supports 51, 52 at the stopped position, and further, the lock member 62 described later. In cooperation with the locking function of the former, it is possible to prevent the former 15 from swinging in the packaging material transport direction.
The connecting projecting member 41 is made of a highly rigid metal, alloy, or the like.

Next, the machine body side connecting portion (or former connecting holding portion) 50 will be described. As shown in FIG. 2A, the machine body side connecting portion 50 is a pair of supports extending from the main body wall 11A of the machine body 11 along the insertion direction of the connecting projecting member 41 (an example of the support). That is, it is composed of an upstream support 51 and a downstream support 52. The pair of supports 51 and 52 have their facing surfaces extending in parallel with each other along the insertion direction of the connecting projecting member 41 at predetermined intervals in the width direction of the connecting projecting member 41.

Three support members are provided at specific installation positions between the facing surfaces of the pair of supports 51 and 52. As shown in FIG. 3, the three support members are the first and second upper contact members 53 and 54 located on the upper side and the lower contact members located on the lower side depending on the installation height. It is divided into 55.

More specifically, between the facing surfaces of the pair of supports 51 and 52, a lower contact member 53 that contacts the connecting projecting member 41 on its lower surface (lower side) and the lower contact member 53. Also includes first and second upper contact members 53 and 54 that are located closer to the machine body 11 and come into contact with the upper surface (upper side) of the connecting projecting member 41.

Here, the mounting height of the lower contact member 55 (more accurately, the height of the upper surface of the lower contact member 55) is the height of the lower surface of the connecting projecting member 41 at the time of insertion. On the other hand, the mounting height of the first and second upper contact members 53 and 54 (more accurately, the height of the lower surface of each upper contact member 53 and 54) is the tip region of the connecting projecting member 41. It is located higher than the contact member 55 by a value corresponding to the height difference from the lower surface to the upper surface of 41C.

Since the step structure is such that the upper and lower contact members 53 to 55 cooperate with each other to cantileverly support the former 15 via the former connecting portion 40 by the machine body side connecting portion 50. In addition, it can support the weight of the former 15.

More specifically, in such a stepped structure with respect to the connecting projecting member 41, the lower contact member 55 is the weight of the former 15 and its connecting portion 40 when the former 15 is cantilevered. On the other hand, the upper contact members 53 and 54 prevent the rotational movement of the connecting projecting member 41 around the fulcrum (contact point) of the lower contact member 55. However, the height of the former 15 can be determined.

From this point of view, if the lower contact area (for example, 55) with respect to the connecting projecting member 41 is closer to the former 15 than the upper contact area (for example, 53, 54), the above Arrangements of other numbers of contact members capable of exerting weight support and rotation prevention functions may be adopted. For example, the upper contact members 53 and 54 may be either one, and only one upper contact member 54 farther from the lower contact member 55 may be provided in the upper stage.

Further, in the connecting means shown in FIGS. 1 to 4, the connecting position of the former side connecting portion 40 (connecting protruding member 41) and the machine body side connecting portion 50 is on the side of the former 15 in the direction toward the machine body 11. Located in the direction. In other words, the former side connecting portion 40 (connecting protruding member 41) and the machine body side connecting portion 50 are connected in the middle from the former 15 to the machine main body 11.

Since the connection is performed at such a position, the former side connecting portion 40 is connected to the machine body side at a shorter distance as compared with the conventional example in which the former is fixed to the packaging machine body via the vertical arm and the horizontal arm shown in FIG. It can be connected to the portion 50 and can be stably supported even when it is cantilevered. In particular, since the vertical arm can be omitted, runout that occurs when the rigidity of the arm is weak does not occur, and since the structure above the former is eliminated, the work of replacing the former 15 and the work of handling the packaging material Fw become easy.

Further, the first upper contact member 53 is provided at the height of the tip region 41C of the connecting protruding member 41, while the step portion is located at the base end side position of the tip region 41C of the connecting protruding member 41. 41B is provided. Moreover, the step portion 41B is formed as a step portion having a height equal to or higher than the height corresponding to the radius of the first upper contact member 53. Therefore, when the connecting projecting member 41 is inserted, the step portion 41B and the first upper contact member 53 come into contact with each other, thereby restricting further insertion of the connecting projecting member 41. This position is set as a predetermined insertion stop position. Therefore, with this configuration, it is possible to appropriately set a predetermined appropriate insertion depth, that is, a predetermined distance of the former 15 to the machine body 11.

It should be noted that such a configuration is only an example, and the means for restricting and stopping the insertion of the connecting projecting member 41 at a predetermined position is not limited to this configuration, and may be realized by other configurations.

[Lock member and air cylinder device]
Next, the lock member 62 and the air cylinder device 60 (an example of a fluid pressure cylinder) in the first embodiment will be described.

As shown in FIGS. 2 to 4, the packaging machine 10 in the first embodiment also includes a lock member 62 and an air cylinder device 60 (an example of a fluid pressure cylinder) for driving the lock means.

First, the air cylinder device 60 is a kind of actuator, and more specifically, it is an example of a fluid pressure cylinder. The air cylinder device 60 includes an air cylinder main body 61A and a cylinder rod 61B projecting from the air cylinder main body. Of these, the air cylinder body 61A is connected and fixed to the downstream support 52 via a fixture (not shown).

Further, as is clear from FIGS. 3 and 4, the tip of the cylinder rod 61B is a columnar member (lock member 62) for restricting the attachment / detachment of the connecting projecting member 41 and fixing the former 15 to the machine body 11. ) Are combined. This columnar member extends in the width direction of the connecting projecting member 41.

Further, as described above, on the lower surface of the connecting projecting member 41, a lock member 62 having a semicircular cross section corresponding to the cross-sectional shape of the columnar lock member 62 is formed over the width direction to form the groove portion 41D. There is.

Further, it is designed so that the groove portion 41D and the lock member 62 can be engaged with each other when the connecting projecting member 41 is inserted and the step portion 41B and the first upper contact member 53 come into contact with each other. .. Therefore, when the connecting projecting member 41 is inserted, the groove portion 41D can be accurately aligned with the position (movement restriction position) where the locking member 62 can receive the lock.

Further, the air cylinder device 60 in which the lock member 62 is attached to the cylinder rod 61B is installed below the first upper contact member 53 at an intermediate position between the first upper contact member 53 and the second upper contact member 54.

Further, the air cylinder device 60 is supplied with high-pressure air from a high-pressure air piping system (not shown) provided with a high-pressure air source via solenoid valves for air supply and exhaust, whereby the air cylinder is supplied. The device realizes the advancing / retreating operation of the cylinder rod 61B with a preset stroke, and can move the lock member 62 to a lock position that prevents the coupling of the connecting means from being released, or retract the lock member 62 from the lock position.

In the first embodiment, the display / operation device 20 is composed of a touch panel type display / input device provided with a touch panel screen. On this display / operation device, a former position fixing switch is displayed so that it can be input and operated. When the operator operates the former position fixing switch on the touch panel, either the forward drive or the backward drive of the air cylinder device 60 is possible. The switch may be configured to switch between forward drive and backward drive each time it is operated, and a former position fixing switch and a former position fixing release switch may be provided separately.

The control device 21 is a microcomputer or the like that controls the operation of each of the above-mentioned components 12 to 19 of the packaging machine 10. The control device 21 is installed in the packaging machine main body 11. The control device includes, for example, a drive control unit (not shown) that controls the drive operation of the air cylinder device 60, which is a drive mechanism, and a touch panel operation control unit (not shown) that controls the operation of the touch panel type display / input device 20. (Not shown) and are provided.

Of these, the air cylinder drive control unit controls the drive operation of the air cylinder device 60 in response to an input signal from the former position fixing switch by the operator.
First, when the former position fixing switch is turned on, the operation is controlled to open the air supply / exhaust solenoid valve (not shown) attached to the air cylinder device 60, and the cylinder rod 61B is moved with respect to the air cylinder body 61A. It advances to the lock position (position of FIGS. (3) and 4 (B)), and with the lock member 62 fitted in the groove 41D, presses the lock member 62 with a constant pressing force of the air cylinder device.

Therefore, as a result, the movement of the connecting projecting member 41 with respect to the machine body side former connecting portion 50 is restricted based on the fitting relationship between the lock member 62 and the groove 41D, and the former 15 is fixed. Further, when the lock member 62 presses the lower surface of the connecting projecting member 41, the movement of the connecting projecting member 41 with respect to the machine body side former connecting portion 50 is further restricted.

Even if the lock member 62 is not pressed by the air cylinder device 60, the above movement regulation can be realized only by the fitting relationship between the lock member 62 and the groove 41D.

On the other hand, when the former position fixing switch is turned off, operation control is performed to close the air supply / exhaust solenoid valve (not shown) attached to the air cylinder device 60, the cylinder rod 61B retracts, and the lock member 62 moves. It returns to a position completely separated from the locked position and stops (positions shown in FIGS. 3A and 4A).

Therefore, the movement restriction of the connecting projecting member 41 is lifted, and the former 15 can be removed.

[Operation of the first embodiment]
When fixing the former 15 to the wrapping machine main body 15, first, the connecting protruding member 41 provided on the former 15 is attached to the upper contact members 53, 54 and the lower contact member 55 of the machine body side connecting portion 50. Insert in between. At this time, the runout regulating projecting members 42, 42 projecting from both side surfaces of the connecting projecting member 41 are inserted at positions where they fit into the supports 51, 52 of the machine body side connecting portion 50.

When the connecting projecting member 41 is inserted, the insertion is performed until the upper contact member 53 and the step portion 41B come into contact with each other, and further insertion is restricted at this position (insertion stop position). When the connecting projecting member 41 is in this insertion stop position, the lock member 62 is located just below the groove 41D.

In this state, when the operator operates the former position fixing switch of the touch panel type display / input device 20, the air cylinder device 60 is driven to move the lock member 62 toward the groove 41D, and the lock member 62 is inside the groove 41D. By pressing the connecting projecting member 41 from the lower surface, the movement of the connecting projecting member 41 is restricted by this pressing action and the movement restricting action due to the locking member 62 being fitted in the groove 41D, and thus the former 15 Can be securely fixed.

When removing the former 15, when the operator operates the former position fixing release switch of the touch panel type display / input device 20, the movement restriction of the connecting protrusion member 41 is released, and the former 15 can be removed.

[Effect of the first embodiment]
With the machine body side connecting portion 50 provided on the machine body 11 side and detachably connecting the connecting projecting member 41 of the former 15 so as to hold the former 15 at a predetermined installation position on the path of the packaging material Fw. A lock member 62 capable of advancing and retreating to a movement restricting position that regulates the movement of the connected protruding member 41 for connection, an air cylinder device 60 that drives the lock member 62, and a touch panel type display / input device 21 from an operator. Since the configuration is provided with the drive control means 21 for controlling the drive operation of the air cylinder device 60 in response to the operation input performed via the above, when the former is attached and fixed, the connection protrusions to the machine body side connecting portion 50. When the member 41 is inserted, the connecting projecting member by the lock member 63 driven by the air cylinder device 60 is simply performed by the operator via the touch panel display / input device 21 to instruct the fixing. Since the movement of 41 can be restricted, the former 15 can be locked, and therefore, when fixing the replaceable former in a predetermined installation position, the force of the operator and subjective judgment are relied on. The former can be securely fixed without any problem.

Further, since the former 15 is configured so that a part of the former (connecting projecting member 41) can be connected to the machine body side connecting portion 50 on the side of the former 15, the former 15 and the machine A fulcrum that supports a part of the former (protruding member 41 for connection) of the former 15 by the main body side connecting portion 50 can be set close to the former, thereby fixing the former 15 having better stability at the time of fixing than before. It can be performed. Moreover, the structure above the former 15 can be eliminated, and the operator can enjoy the additional merit that the operator can work in a wide work space when the former is replaced or the packaging material is set.

Regarding this point, in the technique shown in FIG. 6, since the former needs to be fixed manually, there is a restriction that the tightening bolt or the like must be arranged at a position where the tightening work can be easily performed. By using the cylinder device 60, this restriction can be eliminated, the space around the packaging machine can be effectively utilized, and the operator is not forced to perform the tightening work in an unreasonable posture.

The machine body side connecting portion 50 is divided into an upper stage and a lower stage between the pair of supports 51 and 52, and is bridged substantially horizontally, respectively, and at least one abuts on the lower surface and the upper surface when the connecting projecting member 41 is inserted. It is provided with one lower contact body 55 and at least one upper contact body 53, 54, and since the lower contact member 55 is on the former side of the upper contact members 53, 54, a protrusion for connection is provided between them. When the member 41 is inserted, it can be reliably supported.

Since the insertion restricting means for restricting the insertion of the connecting projecting member 41 at a predetermined insertion stop position is provided, positioning in a direction orthogonal to the transport direction of the packaging material with respect to the installation position of the former (positioning the center position) Can be done easily and accurately.

When the insertion restricting means is composed of the step portion formed on the upper surface of the connecting projecting member and the upper contact body closest to the former, the center position is assured without increasing the number of parts. Can be positioned.

The lock member 62 is configured to have a function of pressing the lower surface of the connecting protruding member 41 at the movement restricting position by the air cylinder device 60 when the connecting protruding member 41 is located at the above-mentioned insertion stop position. The main force of the air cylinder device 60 can be used to fix the connecting projecting member 41 with a constant force. As a result, it is possible to solve the problem of the force of the operator, which is a problem when the fixing work is performed manually, and it is possible to securely fix the former.

The connecting protruding member 41 is provided with a groove 41 corresponding to the shape of the movement restricting means on the lower surface, and when the connecting protruding member 41 is located at the insertion stop position, the groove 41D reaches the movement restricting position and locks. Since the member 62 is configured to be engageable with the groove portion 41D, when the lock member 62 engages with the groove portion 41D, the movement restriction lock of the connecting protrusion member 41 based on the mutual shape is realized, and the connecting protrusion member 41 is realized. It is possible to prevent the 41 from coming off, and it is possible to more reliably prevent the displacement of the center position of the former 15.

Since the connecting projecting member 41 is provided with a pair of runout prevention projecting members 42, 42 projecting from both side surfaces, the connecting projecting member 41 is further fixed by the lock member 62 while being inserted and fixed. The support at three points can effectively prevent the former 15 from swinging in the horizontal direction.
