Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier used for carrying plate-like objects such as glass plates.

[0002]

2. Description of the Related Art When transporting a large glass plate having a size of, for example, 1200 mm × 2000 mm, a glass plate carrier has conventionally been used so that the glass plate can be safely transported without damaging the glass plate. Has been.

Such a glass plate carrier has a base portion and a back support which is provided upright on the rear edge portion of the base portion, and a plurality of stacked glass plates are placed in an upright state. , The lower edge is supported by the base, and one side of the glass plate is received by the backrest.
A holding portion is arranged on the inner surface side of a front frame that is erected on the front edge of the base portion, and the holding portion holds down the front portion of the glass plate to fix the glass plate. And 1
This restraint is connected to the front frame via a screw feed type adjustment mechanism so that the front restraint can be positionally adjusted in the front-rear direction according to the number of glass plates carried by one carrier, that is, the amount transported. By adjusting and operating the screw feed mechanism, the screw feed mechanism is moved forward and backward.

[0004]

However, the amount of the glass sheet to be carried varies from time to time, and therefore the front face restraining position must be adjusted each time. In the conventional configuration in which the screw is moved back and forth, it takes time to adjust the screw feed, which deteriorates the efficiency of the transportation work.

Further, when the amount of glass plates to be transported is large,
If a large stroke configuration is adopted for the screw feed mechanism so that it can handle both cases where the number is small, and the amount of glass sheet transported is large, the restraint will also approach the front frame side, and the screw of the screw feed mechanism will move forward by that amount. Since it is largely projected in the front of the frame, a space problem is caused, and therefore, it is not possible to secure a too large restraining stroke. Therefore, in the past, the stroke for restraint was set small, and when the amount of glass sheet transported was small, emergency measures were taken, such as disposing a cushioning material such as styrene between the restrainer and the front surface of the glass sheet. It was

In addition, as described above, in the constitution in which the front surface restraint of the glass plate is moved forward and backward by the screw feeding mechanism,
When the screw feed mechanism is adjusted to a fixed position and there is a gap between the glass plates, vibration during transportation may cause the glass plates to impact each other due to the gap. However, there is a risk that the glass plates may come into contact with each other and cause damage to the glass plate, etc., and it was not always satisfactory in terms of front restraint performance.

In view of the conventional problems as described above, the present invention can efficiently adjust the position of the front side restraint in the front-rear direction without any trouble, and further, the forward / backward stroke of the restraint can be performed in a space. It is an object of the present invention to provide a carrier that can be secured large without causing a physical problem and can realize a proper restrained state regardless of the amount of the plate-like object.

Still another object of the present invention is to provide a carrier capable of exhibiting excellent front surface restraining performance and effectively preventing damage to a plate-like object.

[0009]

To achieve the above object, the present invention is directed to a base portion which supports a lower edge portion of a plate-like object such as a glass plate, and a plate portion which is erected on a rear edge portion of the base portion. A carrier for a plate-like object such as a glass plate provided with a back support for receiving the back of an object, wherein a front frame is provided in a standing state at a front edge portion of a base portion, and an inner surface side of the front frame is provided. A glass plate, etc., characterized in that a holding piece for holding the front surface of the plate-like object is provided, and the holding piece is connected to the front frame via an expansion / contraction mechanism by a link in such a manner that it can be moved forward and backward. The outline is a plate-shaped material carrier.

Further, the expansion and contraction mechanism by the above-mentioned link includes an upper link and a lower link, and the lower link is
It extends diagonally upward from the front frame side toward the restraining piece side, one end of which is pivotally attached to the front frame and the other end is pivotally attached to the restraining piece, and the upper link is from the front frame side to the restraining piece side. It is preferable to extend obliquely downward toward one end, one end of which is pivotally attached to the front frame so as to be vertically movable, and the other end of which is pivotally attached to the restraining piece.

Further, in this case, the upper link and the front frame are provided with guide rails provided on the front frame and extending in the vertical direction, and a slider is mounted so as to be slidable in the vertical direction. In a configuration mode in which the portion is pivotally mounted, the slider is pivotally mounted so as to be movable in the vertical direction, and the slider is mounted on the guide rail with play, and by utilizing this play, the front frame side of the upper link is utilized. When a downward force is applied to the end of the upper link, the downward movement of the upper link end is permitted against the frictional force between the slider and the guide rail, while the upper frame end of the upper link is It is preferable that when an upward force is applied to the upper end of the upper link end portion, the frictional force between the sliding portion of the slider and the guide rail prevents the upper link end portion from moving upward.

[0012]

In the above structure, since the expansion / contraction mechanism using the link is adopted as the mechanism for connecting the restraining piece to the front frame so as to be able to move back and forth in the forward and backward directions, the restraining piece can be moved forward and backward in the forward and backward direction efficiently. The plate can be efficiently adjusted to the holding position according to the size of the plate.

Moreover, by adopting the expansion and contraction mechanism by the link in this way, an extra item does not project forward of the front frame due to the forward / backward movement of the restraining piece, thus causing a space problem. Without letting
The holding piece can be moved back and forth with a large stroke in the front-rear direction, and an appropriate holding state can be realized regardless of the size of the plate-like object.

Further, the expansion and contraction mechanism by the link includes an upper link and a lower link, and the lower link extends obliquely upward from the front frame side toward the holding piece side, and one end thereof is the front frame. And the other end is also pivoted to the restraining piece.
On the other hand, the upper link extends obliquely downward toward the front frame side restraining piece side, one end is pivotally attached to the front frame so as to be vertically movable, and the other end is pivotally attached to the restraining piece. By doing so, the same operation as described above is achieved, and its structure is simplified as a connecting mechanism between the restraining piece and the front frame,
Moreover, the restraining piece is biased in the advancing direction by its own weight and the own weight of the link, and is automatically set to the optimum position corresponding to the front surface position of the plate-like object.

In this case, the upper link and the front frame are provided with guide rails provided on the front frame and extending in the vertical direction, and a slider is mounted on the slider so as to be slidable in the vertical direction. In a configuration mode in which the portion is pivotally mounted, the slider is pivotally mounted so as to be movable in the vertical direction, and the slider is mounted on the guide rail with play, and by utilizing this play, the front frame side of the upper link is utilized. When a downward force is applied to the end of the upper link, the downward movement of the upper link end is permitted against the frictional force between the slider and the guide rail, while the upper frame end of the upper link is When an upward force is applied to the upper part, the frictional force between the sliding part of the slider and the guide rail prevents the upper end of the upper link from moving upward, for example, vibration during transportation. Between plates When the position of the front surface of the plate-like object recedes due to the gap, the restraining piece follows this and advances to the side of the plate-like article, while the restraining piece is prevented from moving in the receding direction. The excellent front restraint performance is exhibited for the plate-like objects, and the shocking contact due to the gap between the plate-like objects is automatically suppressed by the vibration during transportation.

The slider (17) is provided on the outer periphery of the guide rail (16) with a predetermined play, and the play is utilized to make the slider (17) and the guide rail (1).
6) Change the frictional force between it and the upper link (1
When a downward force is applied to the front frame (4) side end of 4), the lower end of the upper link (14) is allowed to move downward, while the upper link (14) is allowed to move downward. When an upward force is applied to the same end portion of (14), the upward movement of the same end portion of the upper link (14) is blocked.

That is, as shown in FIG. 5, the sliding inner peripheral surface of the slider (17) is such that the front surface (20) is inclined obliquely forward toward the upper side and the rear surface is Is
The upper half portion (22) is cut off at the boundary of the middle portion (21) in the height direction, and the lower half portion (23) of the lower half portion (23) is inclined forward and upward at the same inclination angle as the front side. It is inclined so that the slider (17) has a play with respect to the guide rail (16). As a result, as shown in FIG. 7, when an upward force is applied to the end portion of the upper link (14), the lower end portion of the front surface (20) of the sliding inner peripheral surface of the slider (17). (24) and the rear surface-side intermediate portion (21) in the height direction are strongly abutted on the guide rail (16), while the end of the upper link (14) as shown in FIG. When a downward force is applied to the section, the front upper end portion (25) and the lower end portion (26) of the rear surface of the sliding inner peripheral surface of the slider (17) are guided by the guide rail ( It is designed to come into contact with 16) with relatively weak force. Then, depending on the relationship between the difference between these forces and the friction coefficient, the upper link (1
When an upward force is applied to the end of 4), the upward movement of the end of the upper link (14) is blocked, and a downward force is applied to the end of the upper link (14). In this case, the downward movement of the end portion of the upper link (14) is allowed.

Incidentally, in the case of this embodiment, as shown in FIG. 5, the height h of the main body of the slider (17) is 20 m.
m, height h1 of the lower half of the rear surface (23) of the inner peripheral sliding part of the annular part
Is 9 mm, the width b of the guide rail (16) in the front-rear direction is 20
mm, the inclination angle α of the front surface side (20) of the inner peripheral portion of the slider main body is set to 13 °, and the inclination angle α of the lower half portion (23) of the inner peripheral sliding portion is also set to 13 °. And the pivot part (1
The horizontal distance T between the pivoting center position of 8) and the central position of the slider body is set to 52 mm, and the vertical distance V between the pivoting center position of the pivoting part (18) and the lower surface of the slider body is set to 20 mm. .

Here, as shown in FIG. 6, when a force P in the glass holding direction acts on the holding piece (5), the force P1 for moving the slider (17) downward and its movement. As for the relationship with the frictional force F that tries to prevent the above, assuming that the drag force between the slider (17) and the guide rail (16) is R and the friction coefficient is 0.2, the upper link (14) is calculated. When the angle θ with the vertical direction is at least in the range of 12 to 56 °, the force P1 for moving the slider (17) downward becomes larger than the frictional force F, and this frictional force is counteracted. Then, the restraining piece (5) can move rearward, that is, in the glass sheet restraining direction.

Further, as shown in FIG. 7, when the forward force P acts on the restraining piece (5), the slider (1
The relationship between the force P1 that attempts to move 7) upward and the frictional force F that attempts to prevent that movement is the same, the drag force between the slider (17) and the guide rail (16) is R,
Assuming that the coefficient of friction is 0.2, the calculation shows that the frictional force F becomes larger than the force P1 for moving the slider (17) upward in the range of θ of at least 12 to 56 °. The frictional force F causes the restraining piece (5) to be prevented from moving forward.

As a mechanism for allowing the restraining piece (5) to advance and for preventing or suppressing the retreat, a mode in which the own weight of the restraining piece (5) and the links (14) and (15) is used, and other various configurations May be adopted.

In the carrying tool (1) having the above structure, first, in the work of accommodating the glass plates (G), the upper crosspieces (10) (10)
Is rotated rearward so as not to get in the way, and the side arms (11) (11) and the front frame (4) are removed. And a plurality of glass plates (G)
..., in a state of standing up and overlapping, with its lower edge supported on the base (2), and at the same time, the glass plate (G).
Place the back side of the back on the back support (3). Then, the front frame (4) is attached, the upper crosspieces (10), (10) are tilted forward and hooked on the front frame (4), and the distance between the backrest (3) and the front frame (4) is increased. Is held at a fixed interval.

In this state, the left and right restraining pieces (5) (5)
Is released from the locked state by the ring (19) and guided to the expansion and contraction mechanism (6) by the links (14) and (15), and is advanced to the front side of the glass plate (G). G) Hold the front side. The pushing operation of the restraining piece (5) is performed very efficiently by the worker by utilizing the biasing force of the restraining piece (5) and the links (14) and (15). can do.

Further, unlike the case of the screw feed type, there is no excessive suppression due to an operation error.

Further, in the front holding state, the holding piece (5) depends on the own weight of the holding piece (5) and the own weight of the links (14) and (15).
Is biased toward the front side of the glass plate (G), and further, a strong frictional force is generated between the slider (17) and the guide rail (16) in the direction opposite to this biasing direction. Therefore, the restraining piece (5) is prevented from moving in the backward direction, and the restrained state is reliably maintained.

Further, when the amount of the glass plates (G) ... Is small, the pressing piece (5) can be greatly advanced to suppress the front surface thereof, and the amount of the glass plates (G). When the number is large, it is possible to reduce the amount of advancement of the restraining piece (5) and perform the front restraining. In that case, in the advancing mechanism (6) by a link, an extra thing does not project to the front side of the front frame (4), and a space problem does not occur. Therefore, regardless of whether the amount of transportation of the glass plates (G) is large or small, the pressing piece (5) is advanced and retracted with a large stroke to effectively hold down the front surface of the glass plate (G) with the pressing piece (5). be able to.

Further, in the structure in which the receiving surface of the backrest (3) is inclined so that the glass plates (G) are inclined and received along it, the upper link (1)
Since the end on the front frame (4) side of 4) is pivotally attached so that it can move in the vertical direction, the restraining piece (5) moves in the advancing direction as shown in FIG. In the course of the process, the displacement is performed from the upper side to the lower side, so that the restraining piece (5) can be caused to perform the contact behavior corresponding to the inclination of the front surface of the glass plate (G).

Then, as described above, the glass plate (G)
While the carrier (1) accommodating ... is transported by being loaded on a truck or the like, due to vibration during transportation, due to a gap between the glass plates (G), the front position of the glass plate (G) When the arm moves back slightly, the restraining pieces (5) and (5) move forward so as to follow it, while the restraining piece (5) acts on the frictional force between the slider (17) and the guide rail (16). Since the transition to the front frame (4) side is blocked, the gap between the glass plates (G) ... is closed, and therefore the glass plates (G) ... are fixed more firmly. As a result, it is possible to effectively prevent breakage or damage of the glass plates (G) ... due to shocking contact between the glass plates due to vibration during transportation.

After transportation, the slider (17) is allowed to play in the opposite direction to reduce the frictional force between the slider (17) and the guide rail (16), and in that state, the restraining piece (5). Retract (5) to the front frame (4) side and ring (19)
Then, the side arm (11) and the front frame (4) are removed, and the glass plates (G) are taken out in that state.

Therefore, the efficiency of transportation work can be improved.

Moreover, by adopting the expansion and contraction mechanism by the link as described above, there is no possibility that an extra object is projected to the front of the front frame due to the forward / backward movement of the restraining piece, thus causing a space problem. It is possible to move the restraining piece forward and backward with a large stroke in the front-rear direction without doing so, and realize an appropriate restraining state according to each amount regardless of whether the amount of plate-like objects is large or small. be able to.

Between plates When the position of the front surface of the plate-like object recedes due to the gap, the restraining piece follows the plate and advances to the plate-like side, while the restraining piece is prevented from moving in the backward direction, and therefore, especially during transportation. The excellent front restraint performance is demonstrated for the plate-like objects, and the shocking interference caused by the gap between the plate-like objects can be automatically suppressed by using the vibration during transportation, which is safe for transportation. The property can be further improved. Moreover, since the friction between the slider and the guide rail is used, the intended purpose can be achieved with a simple configuration.
