In the glass plate pressing device of Patent Document 1, the upper portion of the glass plate pressing device disposed in the vertical direction is provided in the vicinity of the glass plate mounted on the glass plate package. Therefore, when the glass plate loading device mounts the glass plate to the glass plate packing body, the glass plate loading device interferes with the upper and lower direction driving portions, and the glass plate removing device removes the glass plate from the glass plate packing body. When the glass plate take-out device interferes with the above-described up-and-down direction driving portion. That is, the glass plate pressing device of Patent Document 1 has an influence The problem of the glass plate loading operation of the glass plate package and the glass plate removal operation.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a glass plate pressing device for a glass plate package which can improve the workability of loading a glass plate to a glass plate package and the workability of taking out a glass plate.

In order to achieve the above object, the present invention provides a glass plate pressing device for a glass plate package, which is a glass plate that abuts against an end surface of a glass plate mounted on a glass plate package and restricts lateral movement of the glass plate. a pressing device; and includes a linear moving portion and a rotary driving portion, the linear moving portion including: a pressing member disposed opposite to an end surface of the glass plate and movably disposed forward and backward with respect to the end surface, and abutting the above An end surface of the glass plate; and a first cam having one end coupled to the pressing member and having a first cam surface at the other end; the rotation driving portion including a second cam disposed on the same axis as the first cam And being rotatably mounted around the axis of the first cam, and having a second cam surface that is in surface contact with the first cam surface of the first cam at one end; and a rotary drive unit provided The second cam is rotated at the other end of the second cam; and the second cam surface is rotated by the rotation operating member of the rotation driving unit, whereby the second cam surface and the first cam surface are Push effect Via the first cam so that the pressing member relative to the end face of the glass sheet moves forward and backward.

The glass plate pressing device of the present invention is a structure in which the first cam and the second cam that drives the first cam protrude outward from the end surface of the glass plate and protrude in a direction facing the end surface, and the machine height is low. Therefore, the glass of the present invention In the case of the glass plate pressing device, when the glass plate is loaded onto the glass plate, the glass plate loading device does not interfere with the glass plate pressing device, and when the glass plate is taken out from the glass plate packing body, there is no glass plate. The take-up device interferes with the flaw of the glass plate pressing device. Therefore, according to the glass plate pressing device of the present invention, the workability of the glass plate of the glass plate package body and the take-out workability of the glass plate are improved.

According to the glass plate pressing device of the present invention, when the operation of loading the glass plate with the glass plate loading device by the glass plate loading device is completed, the second cam is rotated in the pressing direction by the rotation operation member of the rotation driving member. By the pushing action of the second cam surface of the second cam and the first cam surface of the first cam, the pressing member is moved forward toward the end surface of the glass plate via the first cam, and the pressing member is brought into contact with the glass plate. End face. Thereby, the end surface of the glass plate mounted on the glass plate package can be pressed, so that the lateral movement of the glass plate can be restricted. Further, when the glass plate is taken out from the glass plate package by the glass plate take-up device, the second cam is rotated in the release direction by the rotary operation member. Thereby, the pressing force of the pressing member against the end surface of the glass plate is released, so that the glass plate can be taken out from the glass plate packing body.

Preferably, the first cam surface and the second cam surface of the present invention have a three-dimensional curved surface such that the cam faces of the two cams face each other in the range of the rotation of the second cam.

According to the invention, in the range of the rotation of the second cam, the second cam surface is operated in a state of being in constant surface contact with the first cam surface, so that the pressing member smoothly moves forward and backward. Further, since the cam surface is prevented from being scratched by the cam faces being in line contact with each other, the cam surface can be prevented from being damaged. Furthermore, The first cam surface having the three-dimensional curved surface and the second cam surface can be formed by polishing with a grinding stone whose axis is inclined with respect to the axis of the cam, and this manufacturing method is known.

Preferably, the first cam surface and the second cam surface of the present invention have a regulating surface that restricts advance and retreat movement of the first cam at a position where the first cam is farthest from the second cam. .

According to the invention, the first cam surface and the second cam surface are respectively disposed on the cam surfaces at positions where the first cam is farthest from the second cam, that is, the pressing member presses the end surface of the glass plate. Since the restriction surface of the end portion (cam distal end portion) of the lifting portion is in contact with each other, the movement of the first cam is restricted, and the movement of the pressing member is restricted. That is, the movement of the pressing member can be locked by the abutment of the above-mentioned restriction surfaces. In the present invention, since the mechanism for locking the movement of the pressing member is provided on the first cam surface and the second cam surface, the number of components can be significantly reduced as compared with the case where another locking mechanism is separately provided. Further, when the rotation operation member is rotated in the release direction, the contact faces of the first cam and the second cam are released, so that the pressing force of the pressing member against the end surface of the glass plate can be released. .

Preferably, the linear movement unit according to the present invention includes a biasing member that urges the pressing member in a direction in which the pressing member retreats from an end surface of the glass sheet toward a direction facing the end surface. .

According to the present invention, when the pressing force of the pressing member on the end surface of the glass sheet is released by the screwing operation of the rotary operating member, the pressing member is biased from the end surface of the glass sheet by the biasing force of the biasing member. The end faces are retracted in opposite directions. That is, the biasing force of the urging member is transmitted from the pressing member to the first cam, The first cam surface, the second cam surface, and the second cam. When the rotation operation member is rotated in the release direction in this state, the first cam surface and the second cam surface are pressed against each other by the biasing force, so that the first cam surface and the second cam surface are pushed. The pressing member is retracted from the end surface of the glass sheet. That is, according to the present invention, since the pressing member can be sufficiently retracted from the end surface of the glass sheet by providing the urging member, the operation of taking out the glass sheet from the glass sheet packing body can be surely performed.

Preferably, the pressing member of the linear movement portion of the present invention is coupled to the first cam via a nut and a screw to which the nut is screwed.

According to the present invention, the torque nut is used to rotate the nut so that the nut is moved a small amount toward the end surface of the glass plate with respect to the screw, whereby the pressing member is pressed against the end surface of the glass plate by the nut, and is rotated by the torque wrench. The nut until the torque at this time reaches the torque that can reliably press the glass plate. And, according to the present invention, the glass sheet can be reliably pressed by managing the torque obtained by the torque wrench.

Further, it is preferable that a cushioning material is provided on the front side of the pressing member that abuts against the end surface of the glass sheet. When the glass sheet is to be laterally displaced due to vibration during transportation, the lateral shift is absorbed by the cushioning material, so that damage to the edge portion of the glass sheet can be prevented.

As described above, according to the glass plate pressing device of the glass plate package of the present invention, it is possible to improve the workability of the glass plate for the glass plate package and the workability of taking out the glass plate.

Hereinafter, a preferred embodiment of the glass plate pressing device of the glass sheet package of the present invention will be described with reference to the accompanying drawings.

Further, the main surface of the bottom support plate 18 is not formed with a substantially flat surface such as a groove into which the glass sheet G is inserted, but the glass sheet G may be placed on the partition paper (not shown). It is corrugated or rough. The bottom support plate 18 is disposed such that its main surface is preferably inclined by 5 to 25 degrees, more preferably by 10 to 20 degrees, and more preferably by about 18 degrees with respect to the mounting surface 16 of the base 14. With this, When the glass plate is loaded onto the glass plate packing body 12 by the glass plate loading device, the positioning operation of the glass plate G becomes easy. Further, since the main faces of the respective glass sheets G, G, ... are in contact with the main surface of the glass sheet G on the back support plate 22 side due to their own weight, the main faces of the respective glass sheets G, G, ... are not There will be extra gaps. Further, stabilization of the placed glass sheet G can be achieved, and the glass sheet G can be prevented from being displaced or collapsed toward the front (in the direction of the arrow X in FIG. 1), and damage or cracking can be prevented.

The glass plate pressing device 10 of the embodiment sandwiches the glass plate G in the vicinity of the side connecting portion of the bottom support plate 18 and the back support plate 22 from the left-right direction (the direction of the arrow Y orthogonal to the arrow X in Fig. 1). In this manner, two units are provided on the mounting surface 16 of the susceptor 14.

2 is a longitudinal sectional view showing a configuration of a glass plate pressing device 10, FIG. 3 is a perspective view showing a configuration of a main portion of the glass plate pressing device 10, and FIG. 4 is a glass plate pressing device 10 shown in FIGS. 2 and 3. A perspective view of the configuration of the linear moving portion 34. Further, since the two glass plate pressing devices 10 and 10 have the same configuration, only the configuration of the glass plate pressing device 10 disposed on the right side of FIG. 1 will be described here, and the glass plate pressing device 10 disposed on the left side will be omitted. Description. In addition, in FIGS. 2 and 3, in order to clearly show the internal structure of the glass plate pressing device 10, the top plate 32 of the main body casing 30 (see FIG. 1) of the glass plate pressing device 10 is removed.

The glass plate pressing device 10 of the embodiment includes a linear moving portion 34 and a rotary driving portion 36 as shown in Figs. 2 and 3 .

The linear moving portion 34 includes a pressing plate (pressing member) 38 and a cam (first cam) 40, and the pressing plate 38 and the cam 40 are screwed through a screw 44 that is screwed with a nut 42. And the link. The cam 40 is formed in a substantially angular column shape. One end surface 46 of the cam 40 facing the pressing plate 38 is a flat surface orthogonal to the axis A of the cam 40, and the other end surface of the cam 40 is provided with a cam surface (first cam surface) as shown in FIG. .

Further, as shown in FIG. 3, the cam 40 is housed in the angular column-shaped guide tube 50 such that the axis A is horizontal (the direction of the arrow Y). Further, the cam 40 is only in the horizontal direction in a state where the outer surface of the cam 40 is in sliding contact with the inner wall surface of the guide tube 50, and the rotation about the axial center A with respect to the guide tube 50 is restricted. Move freely. The guide tube 50 is fixed to the main body casing 30 of the glass plate pressing device 10 (see FIG. 1), and the main body casing 30 is detachably fixed to the mounting surface 16 of the susceptor 14 by bolts 52 as shown in FIG.

Fig. 5 is a perspective view showing the shapes of the cam faces 48 and 72 of the two cams 40 and 68 shown in Figs. 2 and 3 . Further, in FIG. 5, the axis A is curved in order to clearly show the shape of each of the cams 40, 68. As shown in FIGS. 4 and 5, one end of the screw 44 is screwed into a screw hole 54 formed in the same axis as the axis A of the cam 40, and screwed to the outlet provided at the screw hole 54. The nut 56 is thereby fixed to the cam 40. On the other hand, the other end portion of the screw 44 is inserted into a through hole (not shown) fixed to the joint portion 58 of the back surface (the surface on the cam 40 side) of the pressing plate 38. Thereby, the pressing plate 38 is movably coupled to the screw 44 in the horizontal direction (the direction of the arrow Y in FIG. 2), and the pressing plate 38 is opposed to the cam 40 by adjusting the position of the nut 42 with respect to the screw 44. The distance is finely adjusted.

The pressing plate 38 is a rectangular plate with the long side portion facing the horizontal direction. Mounted at the other end of the screw 44. Further, a cushioning material 60 made of rubber or a hard foaming resin is attached to the front surface of the pressing plate 38 facing the end surface G1 of the glass sheet G. The cushioning material 60 abuts against the end surface G1 of the glass sheet G. Further, the cushioning material 60 is not essential, but has an advantage that the cushioning member 60 can absorb a slight lateral shift of the glass sheet G loaded on the bottom support plate 18, and can prevent the end face G1 of the glass sheet G. Since the glass plate G is damaged by the contact with the pressing plate 38, it is preferable to provide the cushioning material 60 on the pressing plate 38.

Further, in a form in which the glass sheet G is laminated on the glass sheet packing body 12 with the spacer sheets interposed therebetween, and the both sides of the spacer sheet protrude from both ends of the glass sheet G, the pressing sheet 38 is interposed and extended. The end face G1 of the glass sheet G is pressed by the spacer paper. In this case, the extended spacer paper has a buffer function. Further, in order to provide a buffer function, at least one of the cushioning material 60 and the spacer paper may be provided.

Further, as shown in FIG. 3, by arranging a pair of springs (urging members) 62, 62 in the horizontal direction via the screw 44, the pressing plate 38 is received in the horizontal direction with respect to the end surface G1 of the glass sheet G. The force in the direction of retreating. One end of the spring 62 is locked to the locking portion 64 provided on the back surface of the pressing plate 38, and the other end portion is locked to the pin 66 protruding from the side of the guiding tube 50. Further, the spring 62 is not essential, but since the linear movement portion 34 is automatically moved from the end surface G1 of the glass sheet G to the position retracted with respect to the end surface G1 by the spring 62, it is preferably the linear movement portion 34. A spring 62 is provided.

The rotary drive unit 36 includes a cam (second cam) 68 and an operating lever (swivel operating member) 70. The cam 68 is disposed on the same shaft as the cam 40 and will The shaft center A of the cam 40 is pivotally supported on the body casing 30 as a center. Further, the cam 68 is formed in a substantially columnar shape and housed in the guide tube 50, and a cam surface (second cam surface) 72 is provided on an end surface facing the cam surface 48 of the cam 40.

As shown in Fig. 5, the cam surface 48 of the cam 40 and the cam surface 72 of the cam 68 are formed such that the cam faces 48, 72 of the cam 40 are in surface contact with each other within a range of rotation (approximately 180) of the cam 68 described below. 3D surface. Further, the cam faces 48, 72 are always in a state of being pressed against each other by the urging force of the spring 62 shown in Fig. 3. When the cam 68 is rotated as indicated by the arrow R in this state, the cam 68 advances and retracts the drive cam 40 in the horizontal direction with respect to the end surface G1 of the glass sheet G via the cam faces 72 and 48, and thus is coupled to the cam 40 via the screw 44. The pressing plate 38 of the cam 40 moves forward and backward with respect to the end surface G1 of the glass sheet G. That is, the push plate 38 is moved forward and backward with respect to the end surface G1 of the glass sheet G via the cam 40 by the pushing action of the cam faces 48 and 72.

The operating lever 70 is a member that rotates the cam 68 by a manual turning operation, as shown in FIG. 2, in a direction orthogonal to the axis A of the cam 68. 6A to 6C are explanatory views of the operation of the glass plate pressing device 10 of the embodiment. The swiveling operation range of the operating lever 70 is set to be 0° to 180° with respect to the mounting surface 16 as shown in FIGS. 6A, 6B, and 6C, and may be based on the shape of the cams 40 and 68 and the cam faces 48 and 72. The shape is appropriately set.

Further, in order to prevent the glass plate G from coming into contact with the operation lever 70 during loading and removal of the glass sheet G, it is preferable that the rotation position of the operation lever 70 is at the start position (Fig. 6A) and the end position (Fig. 6A). The height of the mounting surface 16 on the mounting lever 70 in FIG. 6C) (H2: see FIG. 6A) is the glass plate pressing device except the operating lever 70. Set the maximum height of 10 (H1: see Figure 6A) below. Therefore, it is preferable that the start angle and the end angle of the swing operation range of the operation lever 70 be the angle of the height H2 described above. In FIG. 6A, the height of the pressing plate 38 is the maximum height H1. However, the height of the pressing plate 38 is not limited to the height of the pressing plate 38, and may be the height of a member other than the pressing plate 38 constituting the glass plate pressing device 10.

Further, on the cam faces 48, 72, as shown in Figs. 2, 5, and 6C, a restricting cam is provided at a position where the cam 40 is farthest from the cam 68, that is, a position at which the operating lever 70 is rotated by 180°. The limit faces 49, 73 of the advance and retreat movement of 40. The restricting faces 49, 73 are provided at the front ends (ends) of the cam faces 48, 72, and are flat faces that are substantially orthogonal with respect to the axis A. When the regulating faces 49 and 73 are in contact with each other, the cams 40 and 68 are pressed against each other via the regulating faces 49 and 73 by the biasing force of the spring 62 of Fig. 3, so that the abutting state is maintained. Thereby, the advancement and retreat movement of the cam 40 is restricted, so that the movement of the pressing plate 38 is locked. In addition, the shape of the regulating surfaces 49 and 73 is not limited to a flat surface, and a curved surface such as a spherical shape or a corrugated shape may be used as long as the regulating surfaces 49 and 73 can be brought into contact with each other.

Next, the features and operations of the glass plate pressing device 10 configured as described above will be described.

The glass plate pressing device 10 of the embodiment is characterized in that it is a structure in which a cam 40 and a cam 68 that linearly drives the cam 40 in the horizontal direction are horizontally outward from the end surface G1 of the glass plate G. Outstanding, and the machine height is low.

Therefore, in the glass sheet pressing device 10 of the embodiment, when the glass sheet is placed on the glass sheet packing body 12, the glass sheet loading device (not shown) does not interfere with the glass. After the glass plate pressing device 10, when the glass plate is taken out from the glass plate packing body 12, the glass plate removing device (not shown) interferes with the glass plate pressing device. Therefore, according to the glass plate pressing device 10 of the embodiment, the workability of the glass plate G of the glass plate package 12 and the take-out workability of the glass sheet G are improved.

Next, the action of the glass plate pressing device 10 will be described.

First, the operating lever 70 is previously rotated to the horizontal position shown in FIG. 6A at the start position of the turning operation, so that the pressing plate 38 is sufficiently retracted from the loading position of the glass sheet G. In this state, the glass sheet G loading device is used to load the glass sheet G into the glass sheet packing body 12. Further, when the loading operation of the glass sheet G is completed, the operation lever 70 located at the horizontal position (0°) shown in Fig. 6A is rotated by 180°.

When the operation lever 70 is rotated, the cam 68 integrated with the operation lever 70 is rotated in the direction in which the cam 40 is linearly driven in the horizontal direction toward the end surface G1 of the glass sheet G as shown in FIG. 6B. Thereby, the pressing plate 38 is moved forward toward the end surface G1 of the glass sheet G via the cam 40 by the pushing action of the cam surface 72 of the cam 68 and the cam surface 48 of the cam 40. When the operating lever 70 is rotated by 180° as shown in FIG. 6C, the pressing plate 38 abuts against the end surface G1 of the glass sheet G. Thereby, the end surface G1 of the glass plate G mounted on the glass plate packing body 12 can be pressed, and the lateral movement of the glass plate G can be restricted.

Further, when the glass sheet G is taken out from the glass sheet package 12 by the glass sheet take-up device, the cam 68 is rotated by the operation lever 70 in the releasing direction opposite to the above direction. Thereby, the pressing force of the pressing plate 38 against the end surface G1 of the glass sheet G is released, so that the glass sheet can be taken out from the glass sheet packing body 12. G.

Since the cam faces 48 and 72 of the glass plate pressing device 10 of the embodiment are formed of a three-dimensional curved surface, the cam surface 72 and the cam surface 48 are always in surface contact with each other in the range of the rotation of the cam 68. Thereby, the pressing plate 38 is smoothly moved forward and backward. Further, since the galling of the cam faces 48 and 72 caused by the cam faces 48 and 72 being in line contact with each other can be prevented, the cam faces 48 and 72 can be prevented from being damaged.

Further, according to the glass plate pressing device 10 of the embodiment, in the state in which the operation lever 70 is rotated by 180° in FIG. 6C, the cam faces 48 and 72 are provided with restriction faces 49 and 73 for locking the movement of the pressing plate 38. Therefore, the number of parts can be greatly reduced as compared with the case where another locking mechanism is separately provided.

When the operation lever 70 is rotated in the release direction from the position of FIG. 6C, the contact faces 49 and 73 of the cam 40 and the cam 68 are released from each other, so that the pressing plate 38 can be released from the glass plate G. The pressing force of the end face G1. At this time, the pressing plate 38 is retracted from the end surface G1 of the glass sheet G by the urging force of the spring 62. That is, the urging force of the spring 62 is transmitted from the pressing plate 38 to the cam 40, the cam surface 48, the cam surface 72, and the cam 68. When the operation lever 70 is rotated in the release direction in this state, the cam surface 48 and the cam surface 72 are pressed against each other by the urging force, so that the pressing is performed by the pushing action of the cam surface 48 and the cam surface 72. The plate 38 is retracted from the end face G1 of the glass plate G. In other words, by providing the spring 62, the pressing plate 38 can be sufficiently retracted from the end surface G1 of the glass sheet G as shown in FIG. 6A, so that the glass sheet G can be surely taken out from the glass sheet packing body 12.

Furthermore, the glass plate pressing device 10 according to the embodiment is as shown in FIG. 6C. In the end surface pressing state, the operator rotates the nut 42 using a torque wrench (not shown) to move the nut 42 toward the end surface G1 of the glass sheet G by a small amount with respect to the screw 44, whereby the pressing plate 38 is pressed by the nut 42. The pressing abuts against the end face G1 of the glass sheet G. Then, the nut 42 is rotated by the torque wrench until the torque measured by the torque wrench reaches a torque that can be reliably pressed without breaking the glass sheet G. That is, according to the glass plate pressing device 10 of the embodiment, the glass plate G can be reliably pressed by managing the torque obtained by the torque wrench.

Fig. 7 is an overall perspective view of a horizontally stacking type glass sheet packing body 80 provided with the glass sheet pressing device 10 of the embodiment.

A plurality of rectangular glass plates (not shown) are stacked on the glass plate package 80 so as to be horizontally and horizontally spaced apart from each other by a rectangular spacer paper 82 having a larger area than the glass plate.

The glass plate packing body 80 is mainly composed of a support base 84 having a rectangular shape in a plan view, a mounting plate 86, a receiving plate 88, and two glass plate pressing devices 10, 10, which are disposed at the side portions of the receiving plate 88. Composition. Further, since the guide members 90, 90, ... as the backing member of the backing plate are vertically arranged at the four corners of the placing plate 86, it is advantageous when the glass sheet packing body 80 is longitudinally laminated in a plurality of stages. .

On both sides of the support base 84, two stacking openings 92 for the forks of the stacker (not shown) are formed on each side of the support base 84. Thereby, the glass plate bundle 80 can be inserted into the fork of the stacker from either of the longitudinal and lateral sides of the support table 84, thereby achieving efficient handling.

The mounting plate 86 is mounted on the support base 84 via a vibration absorbing member (not shown), an inclination angle setting member, and the like, and a receiving plate 88 is fixed to the mounting plate 86.
