[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sheet glass cleaving mechanism and a trimming apparatus. More specifically, by applying a bending force to the plate glass having a cut line for trimming formed on the surface, the narrow end portion (also referred to as an ear) of the plate glass is cut off from the cut line. The present invention relates to a sheet glass cleaving mechanism for removal and a trimming apparatus equipped with the cleaving mechanism.
[0002]
[Prior art]
As a sheet glass trimming apparatus, for example, an apparatus disclosed in Japanese Patent Application Laid-Open No. 8-253336 is known. The trimming apparatus includes an upper pressing member and a lower pressing member for pressing both sides of a sheet glass to be processed with a marking line therebetween. As shown in FIG. 10A, the lower pressing member presses the inner side from the trimming marking lines La and Lb from the bottom to the upper side, and the upper pressing member is outside the marking lines La and Lb of the plate glass G (so-called By pressing the ear portion E side downward from above, a bending force is applied to the plate glass G across the marking lines La and Lb.
The ear E cut along the marking lines La and Lb falls downward. The main body portion B (FIG. 10B) of the plate glass G from which the ear portion E has been removed is transported to another treatment site and cleaved into a predetermined size along a pre-formed marking line.
[0003]
[Problems to be solved by the invention]
In the trimming apparatus described above, the cleaved ears fall downward on the spot, so that they are crushed in the apparatus. That is, it falls below the conveyance path of the plate glass. In order to collect these waste glasses, it is necessary to prepare a space and a container for collecting ears in the apparatus.
[0004]
SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a sheet glass cleaving mechanism and a trimming apparatus capable of forming a peripheral edge of a sheet glass, that is, trimming to remove the peripheral part and transporting and discarding the removed ear part. The purpose is to provide.
[0005]
[Means for Solving the Problems]
The cleaving mechanism of the sheet glass of the present invention is a cleaving mechanism that cleaves the sheet glass by pressing both sides of the cleaving marking line in opposite directions with the cleaving member and the support member. It has a pressing part that presses the plate glass, and a first end face that intersects the pressing part, and is configured to be able to be driven up and down. The support member is arranged in parallel to the first end face of the cleaving member and is first It has an edge that is horizontally spaced from the end surface, and is configured to be driven up and down. A first glass adsorbing portion is disposed on the first end surface of the cleaving member so as to face the support member. The first glass adsorbing part is configured to adsorb the ear part when the plate glass with film is cleaved and the ear part is hung from the film. .
[0006]
By adopting such a configuration, the glass piece of the cleaved plate glass is adsorbed and held by the first glass adsorbing portion of the cleaving member, so there is no possibility that the glass piece falls into the plate glass conveyance path and is crushed. For example, when a plate glass with a film whose lower surface is supported by a support member, for example, when a cleaving member that has been lowered pushes the upper surface downward and applies a bending force to the glass, the plate glass is cleaved from a marking line previously formed on the plate glass. And hanging by the film. The first glass adsorbing member adsorbs the hanging portion. After that, for example, the cleaving member may be moved to discard the glass piece in a predetermined place.
[0007]
And, in the cleaving mechanism in which the first glass adsorbing portion has a plurality of suction ports for adsorbing the plate glass by negative pressure, the glass piece can be adsorbed and released, so that the glass piece Disposal is easy and is preferable. Further, since it is adsorbed by a plurality of adsorbing members, even a narrow and long glass piece such as a trim can be adsorbed and held stably.
[0008]
Further, the pressing portion of the cleaving member is composed of a substantially horizontal surface, a glass support portion and a second end surface intersecting the support member via the edge are formed, and the glass support portion is In the cleaving mechanism constituted by a substantially horizontal surface, when the plate glass is conveyed in a horizontal state by a belt conveyor or the like, it is supported as it is by the horizontal glass support portion. Moreover, since it becomes possible to let the glass piece of the plate glass with a film cut along the 2nd end surface, this glass piece hangs stably and the adsorption | suction by a 1st glass adsorption | suction part will also become reliable. The second end face is generally constituted by a vertical plane, but may be inclined.
[0009]
Further, in the cleaving mechanism in which at least one of the cleaving member and the support member is configured to be reciprocable in a direction in which the cleaving member is separated from and approaching the first, the glass piece that is cleaved and hung by the film is It is preferable because the glass adsorbing member can be approached. That is, it is not preferable to cleave the sheet glass in the state where the cleaving member is close to the support member from the beginning because it is not preferable because there is a risk of interference. This is because it is desirable to make the first glass adsorption member approach the glass piece for easy and reliable adsorption holding of the glass piece.
[0010]
Further, a glass receiving portion formed of a substantially horizontal surface for receiving the cut sheet glass piece is formed below the edge of the support member, and the pressing portion of the cutting member is opposed to the glass receiving portion. In the cleaving mechanism in which the second glass adsorption part is formed as described above, for example, it is suitable for cleaving a plate glass to which no film is attached. This is because when the plate glass to which the film is not attached is cut, the glass receiving part supports the falling glass piece. Furthermore, since the 2nd adsorption | suction part formed in the press part of the cleaving member opposes the glass piece supported by the said glass receiving part, this glass piece can be adsorbed-held easily.
[0011]
Further, the second glass adsorbing portion has a plurality of long suction ports formed in a surface of the pressing portion facing the glass receiving portion, and the long suction ports are In the cleaving mechanism that is arranged in the longitudinal direction and each suction port is configured to adsorb the plate glass by negative pressure, since the suction port is formed in the surface of the pressing portion, It is preferable because it does not get in the way when pressing the plate glass. Furthermore, even if it is a simple suction port, it is a long and thin plate glass because it is long and a plurality of suction ports are arranged in the longitudinal direction of the suction port, and is configured to be adsorbed by negative pressure. However, it can be adsorbed satisfactorily and stably.
[0012]
Further, in the cleaving mechanism in which the cleaving member is configured to be reciprocally movable in the longitudinal direction of the first end surface, for example, even if a narrow long glass piece is adsorbed, Since it moves to a parallel direction, it becomes possible to convey a glass piece to a disposal place, without interfering with another member.
[0013]
Moreover, in the cleaving mechanism apparatus in which the support member is formed with a third glass adsorption portion for adsorbing the plate glass, it is preferable because the support of the plate glass by the support member becomes reliable and stable.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a sheet glass cleaving mechanism and a trimming device of the present invention will be described with reference to the accompanying drawings.
[0021]
FIG. 1 is a perspective view showing an embodiment of a sheet glass trimming apparatus according to the present invention.
2 is a front view of the trimming apparatus of FIG. 1, FIG. 3 is a plan view of FIG. 2, and FIG. 4 is a right side view of FIG. A description will be given with reference to FIGS.
[0022]
The plate glass conveying device in the trimming device 1 is composed of a belt conveyor 2 arranged horizontally. The glass sheet G to be processed is placed on the conveyor 2 and conveyed in the direction of arrow A. This transport direction is referred to as the front, the opposite direction is referred to as the rear, and the horizontal direction perpendicular to the transport direction (front-rear direction) is referred to as the lateral direction, the width direction, or the left-right direction. A cleaving member and a supporting member for trimming for cleaving and removing the edge portions of the plate glass are disposed on the front and rear and on the left and right of the conveyor 2, respectively. The cleaving member and the support member constitute a plate glass cleaving mechanism. These are a front cleaving mechanism including a front cleaving member 3 and a front supporting member 7, a rear cleaving mechanism including a rear cleaving member 4 and a rear supporting member 8, a left cleaving mechanism including a left cleaving member 5 and a left supporting member 9. And a right cleaving mechanism including the right cleaving member 6 and the right support member 10.
[0023]
Each support member 7, 8, 9, 10 is moved up and down by an air cylinder 11. Each of the cleaving members 3, 4, 5, 6 is also moved up and down by the electric servo cylinder 12. The servo cylinder 12 can finely adjust the stroke speed and the stop position. The plate glass G is preliminarily formed with a marking line for cleaving, and the supporting member and the cleaving member are pushed up and down in opposite directions on both sides of the marking line. Specifically, the supporting member supports the lower surface of the glass sheet G, and the cleaving member pushes the opposite side (ear part E) sandwiching the marking line of the glass sheet G downward to apply a bending force.
[0024]
As shown in FIGS. 2 to 4, the front cleaving member 3 and the rear cleaving member 4 are reciprocated in the left-right direction by a so-called rodless cylinder 13 using a mechanical joint. This is because, as will be described later, the edge E of the plate glass that has been cut is carried out to the side of the apparatus 1 and discarded. The rodless cylinder 13 extends from the upper side of the sheet glass G conveyance path to the left side, but may extend to the right side.
[0025]
Further, the left and right cleaving members 5 and 6 and the left and right support members 9 and 10 correspond to the left and right marking lines of the plate glass corresponding to the left and right positioning of the plate glass G by the left and right positioning members 25 and 26 described later. It is comprised so that it may move to the left-right direction. This will be described below.
[0026]
As shown in FIGS. 3 and 4, the left cleaving member 5 and the right cleaving member 6 are reciprocated in the left-right direction by a screw feed mechanism using a screw rod 14 and a nut (not shown). This is for positioning so as to correspond to the width dimension of the plate glass to be cleaved, specifically, the dimension between the left and right marking lines La (FIG. 10A), as will be described later. In addition, the screw rod 14 is divided | segmented into right and left, and is mutually connected by the joint member 15 in these intermediate parts. A left screw is formed on the left screw rod 14a, and a right screw is formed on the right screw rod 14b. The threaded rod 14 is rotated by a single motor 16 via a chain 16a, and the two breaking members 5 and 6 are driven so as to approach and separate from each other synchronously.
[0027]
As shown in FIG. 4, the left support member 9 and the right support member 10 are also reciprocated in the left-right direction by a screw feed mechanism using a screw rod 17 and a nut (not shown). This is because, as described later, the left and right cleaving members 5 and 6 move in the left-right direction for alignment, but need to move in the same direction. The screw rod 17 is also divided into left and right parts and connected to each other by a joint member 18. A left screw is formed on the left screw rod 17a, and a right screw is formed on the right screw rod 17b. The screw rod 17 is rotated by a single motor 19 and is driven so that both support members 9 and 10 approach and separate from each other synchronously.
[0028]
2 to 4, reference numeral 20 is a guide rod for guiding the raising and lowering of the front, rear, left and right cleaving members 3, 4, 5, 6, and reference numeral 21 is front, rear, left and right support members 7, 8, 9, 10. The reference rod 22 is a guide rod for guiding the movement of the left and right cleaving members 5, 6 in the left-right direction. Although not shown, guide rods for guiding the movement of the left and right support members 9 and 10 in the left-right direction are also provided.
[0029]
The trimming device 1 is provided with a front positioning device 23 and a rear positioning device 24 for positioning the glass sheet G in the front-rear direction, and a left positioning device 25 and a right positioning device 26 for positioning in the left-right direction. Has been. The left positioning device 25 and the right positioning device 26 correspond to the width direction positioning device. The plate glass G is moved by these positioning devices 23, 24, 25, and 26 so that the score line is between the cleaving member and the front support member.
[0030]
Although the front positioning device 23 is shown in FIG. 5, the rear positioning device 24 has the same configuration, so that the front positioning device 23 will be described as a representative. This pre-positioning device 23 is a device in which an optical sensor 29 is attached to a movable support 28 that is moved horizontally in the front-rear direction by a drive cylinder 27. The optical sensor is moved to a preset stop position of the glass sheet G. The optical sensor 29 irradiates light through an optical fiber, and detects reflected light reflected on the conveyed glass sheet G. It is not limited to an optical sensor, and other known detectors may be used.
[0031]
As shown in FIGS. 1 to 4, the left positioning device 25 and the right positioning device 26 employ a cylinder 30 for pushing the left and right ends of the glass sheet G toward the center. It is preferable to arrange a plurality of positioning devices on the left and right respectively. A pressing pad 30 a is attached to the tip of the rod of the cylinder 30. The initial position of the cylinder 30 can be adjusted by moving the holding body 30b holding the cylinder 30 in the left-right direction. As this adjusting mechanism, a mechanism that drives a rack and pinion (not shown) by turning the dial 30c can be adopted. Although not shown, a plurality of floating pads for floating the glass sheet G are arranged in the gap between the conveyors 2. When the left and right positioning devices 25 and 26 are operated, the floating pads float the glass sheet. After that, the left and right positioning is performed. This is to facilitate the lateral movement of the plate glass and not to damage the lower surface of the plate glass. The operation of the left and right positioning devices 25 and 26 may be performed in synchronization with the movement of the left and right cleaving members 5 and 6 and the left and right support members 9 and 10 described above.
[0032]
Next, the cleaving member and the supporting member will be described. The lower ends of the cleaving members 3, 4, 5, 6 are arranged above the conveyance path of the plate glass G, and are lowered below the conveyance path by the servo cylinder 12. At this time, the ear E of the plate glass G is pressed. On the other hand, the upper ends of the support members 7, 8, 9, and 10 are arranged below the conveyance path of the plate glass G, and are raised to the conveyance path by the air cylinder 11 to support the plate glass G from below.
[0033]
6 and 8 show the front cleaving member 3 and the front supporting member 7, the rear cleaving member 4 and the rear supporting member 8, the left cleaving member 5, the left supporting member 9, the right cleaving member 6 and the right supporting member. Since the pair of 10 has the same configuration, the pair of the front cleaving member 3 and the front supporting member 7 will be described as a representative. As shown in FIG. 6A, the support member 7 is composed of a long trim receiving bar 31 arranged along the edge of the plate glass G. The trim receiving bar 31 adsorbs the plate glass. The third suction member 32 is disposed. The third adsorption member 32 is connected to an intake means including an ejector (not shown) by a pipe 32a. And suction and release of suction are performed freely.
[0034]
The trim receiving bar 31 has a substantially L-shaped cross section, and an upper end surface of the trim receiving bar 31 is a glass support portion 31 c formed of a horizontal plane, and coincides with the suction surface of the third suction member 32.
The third adsorption member 32 is for fixing the plate glass G to the support member 7 when the ear E of the plate glass G is cleaved. The lower end of the cleaving member 3 descends into the 90 ° opening portion of the L-shaped cross section of the trim receiving bar 31. By this descending, the glass sheet G is folded downward from the marking line. The 90 ° opening portion of the L-shaped cross section of the trim receiving bar 31 is formed with a vertical surface 31a corresponding to the second end surface, and the ear E of the plate glass G with the film cleaved here is hung by the film. Abut. A buffer plate made of rubber or soft synthetic resin may be attached to the surface of the second end surface 31a.
[0035]
On the other hand, the upward horizontal surface formed at the lower portion of the 90 ° opening portion of the L-shaped cross section of the trim receiving bar 31 constitutes the glass receiving portion 31b. The intersection line between the glass support portion 31c and the second end face 31a constitutes the edge of the support members 7, 8, 9, and 10, and this edge supports the bending moment applied when the plate glass G is cleaved from the marking line. It becomes.
[0036]
The cleaving member 3 has a cleaving bar 33 arranged parallel to the trim receiving bar 31 and at a small interval in the horizontal direction. The cleaving bar 33 is located outward from the trim receiving bar 31. The cleaving bar 33 has a rectangular cross section and is moved by the cylinder 34 in a direction approaching and separating from the support member 7. Further, on the support member 7 side of the cleaving bar 33, a vertical surface 33 a that faces the second end surface 31 a of the trim receiving bar 31 in parallel is formed. The vertical surface 33a corresponds to the first end surface. A plurality of first adsorbing members 35 are arranged on the first end surface 33a along the longitudinal direction of the cleaving bar 33 so as to face the second end surface 31a. The first suction member 35 is a trumpet-shaped member made of a flexible material protruding from the first end surface 33a, and a suction port 35a is opened at the center of the trumpet. The suction port 35a is connected to a suction means including an ejector (not shown) through a pipe 35b. And suction and release of suction are performed freely.
[0037]
In the present embodiment, the cleaving bar 33 is configured to be moved in the direction of approaching and separating from the support member 7, but the present invention is not limited to such a configuration. For example, you may comprise so that the supporting member 7 can be moved to the direction which approaches / separates from the cleaving bar 33. FIG.
[0038]
Moreover, in this embodiment, although the 1st end surface 33a and the 2nd end surface 31a are each comprised from the substantially vertical surface, in this invention, it is not limited to a vertical surface. For example, it may be inclined forward or backward from the vertical plane.
[0039]
On the other hand, the lower surface of the cleaving bar 33 is formed horizontally, and this horizontal plane constitutes a pressing portion 36 that presses the ear E of the plate glass G. A plurality of second suction portions 37 are arranged on the pressing portion 36 along the longitudinal direction of the cleaving bar 33 so as to face the glass receiving portion 31b. The second suction portion 37 is a suction port formed in an oval shape, and this suction port is connected to a suction means including an ejector (not shown) by a pipe 37a. And suction and release of suction are performed freely. Since the second suction portion 37 is formed so as to be recessed in the surface of the pressing portion 36, it does not become an obstacle when pressing the plate glass G by the pressing portion 36.
[0040]
As shown in FIG. 6 (b), the major axis of the oval second adsorbing portion 37 is along the longitudinal direction of the cleaving bar 33, and is arranged in a so-called zigzag manner. Of course, you may arrange in a line. By disposing the suction port in this way, the narrow and long ear E can be favorably and stably adsorbed and held.
[0041]
The operation of the trimming apparatus 1 configured as described above will be described.
First, when the plate glass G with a film moves on the conveyor 2 of the apparatus 1, a floating pad (not shown) rises from between the conveyors 2 to float the plate glass G. At the same time, the left and right positioning devices 25 and 26 push the left and right edges of the glass sheet G to a predetermined position set in advance, thereby completing the left and right positioning. When the flying pad descends, the conveyor 2 moves backward to return the glass sheet G. The conveyor 2 stops when the rear positioning device 24 operates to detect the rear end of the glass sheet G. At this time, the marking line Lb (FIG. 10A) at the rear of the glass sheet G is parallel to the first end surface 33a of the rear cleaving member 4 and the second end surface 31a of the rear supporting member 8, and the 33a, 31a Located between. Thus, the position of the rear positioning device 24 is set in advance. This operation is the positioning of the rear end.
[0042]
Next, as shown in FIG. 7A, the rear support member 8 is raised by the air cylinder 11 (FIG. 2), and is opposite to the glass edge of the marking line Lb (FIG. 10A) of the plate glass G. The side is supported from below, and the third adsorption member 32 (FIG. 6) adsorbs the lower surface of the plate glass G.
[0043]
As shown in FIG. 7B, almost simultaneously with this operation, the rear cleaving member 4 is lowered by the servo cylinder 12 (FIGS. 3 and 4), and the pressing portion 36 pushes the ear E of the glass sheet G downward. If it carries out like this, the plate glass G will be contact | abutted to the 2nd end surface 31a of the trim receiving bar 31 in the state which the crack E and the ear | edge part E hung by the film F.
[0044]
As shown in FIG. 7C, the rear cleaving member 4 is lowered as it is, and the first suction member 35 faces the ear E. Thus, the stroke of the servo cylinder 12 is set.
[0045]
As shown in FIG. 7D, the cleaving bar 33 of the rear cleaving member 4 is brought close to the second end surface 31a of the trim receiving bar 31 by the cylinder 34 (FIG. 6). Then, the first suction member 35 operates to suck the ear E.
[0046]
As shown in FIG. 7E, the cleaving bar 33 of the rear cleaving member 4 is returned to the direction away from the trim receiving bar 31 by the cylinder 34 while the first adsorbing member 35 adsorbs the ear E. It is a preparatory operation to ascend without interfering with anything.
[0047]
As shown in FIG. 7 (f), the rear cleaving member 4 returns to its original position even if it is raised by the servo cylinder 12 while adsorbing the ear E. If it does so, the film of the ear | edge part E will peel and it will be in the state by which only the ear | edge part E (only a glass piece) was adsorb | sucked by the 1st adsorption | suction member 35.
[0048]
Next, the rodless cylinder 13 (FIGS. 2 to 4) is operated, and the rear cleaving member 4 is moved upward (leftward) in FIG. When the sheet glass G is taken out from the conveying path, the operation of the first suction member 35 is stopped and discarded in a glass piece collecting container (not shown) in which the ear E is disposed below.
[0049]
When the rear edge trimming is completed as described above, the front edge of the sheet glass is trimmed. That is, the conveyor 2 operates to advance the glass sheet, and stops when the front positioning device 23 detects the front edge of the glass sheet G. At this time, the marking line Lb (FIG. 10A) at the front portion of the plate glass G is located between the first end surface 33 a of the front cleaving member 3 and the second end surface 31 a of the front support member 7.
