Description

  TECHNICAL FIELD The present invention relates to an apparatus for manufacturing an automotive window glass unit, and more particularly, to an apparatus for integrally forming a resin holder connectable to a lifting device on a lower edge portion of an automotive window glass plate. Is.

  For example, as shown in FIG. 12, the lifting device 140 for lifting and lowering the window glass of an automobile is composed of two arms 141 and 142, a lifting rail 143, a fixed rail 144, a regulator (not shown), and the like. Things are known. The two arms 141 and 142 are connected to each other so as to be pivotable about a fulcrum 146, and their upper ends are slidably attached to the lifting rail 143. The lower end of one arm 141 is slidably attached to the fixed rail 144, and the lower end of the other arm 142 is connected to a regulator (not shown) via a rack gear 147. That is, the elevating rail 143 can be moved up and down by driving the rack gear 147 with a regulator.

  The window glass 148 is connected to the lifting rail 143 via two holders 149. The holder 149 is molded from a polyacetal resin containing glass fiber. Generally, after a primer is applied to the window glass 148 and the holder 149, the holder 149 is adhered to the vicinity of the lower edge of the window glass 148 with a urethane adhesive. Can be installed.

  However, in the manufacturing method described above, in order to ensure the adhesive strength of the holder 149, a primer must be applied to the window glass 148 and the holder 149, and accordingly, a primer applying process and a drying process are required. Furthermore, since a relatively long time is required for the adhesive to harden, a large amount of intermediate stock must be held. Moreover, since there are many materials to use, management has been troublesome.

  Furthermore, in recent years, from the viewpoint of promoting the reuse of resources, the recycling of automobile window glass is desired, but if a primer or an adhesive is attached to a glass plate, these materials and the glass material It was difficult to separate the glass plates, making it difficult to recycle the glass plates.

  Therefore, a technique has been proposed in which a resin holder 149 is integrated with the lower edge of the window glass 148 by injection molding (for example, Patent Document 1). In particular, according to this document, a technique is disclosed in which a through hole is formed in the lower edge portion of the window glass 148, and a resin holder 149 is integrated by injection molding into a region including the through hole. . According to this, since the holder 149 can be fixed simply by integrating the resin holder 149 to the window glass 148 by injection molding, a primer coating process and an adhesive bonding process are not required, and the process can be performed in a relatively short time. It becomes possible to manufacture. Further, the window glass 148 and the holder 149 can be separated, and the window glass 148 (glass plate) can be effectively used as a resource.

Republished WO2002 / 070293

  However, in order to realize a method of integrating the holder 149 with the window glass 148 by injection molding, a glass holder for fixing the window glass 148, a mold (for example, a mold) attached to a lower edge portion of the glass plate, In addition, it is necessary to provide an injection unit or the like for injecting the molten resin into the mold, and there is a possibility that the equipment becomes complicated. In particular, since at least two holders 149 are formed apart from each other with respect to the lower edge portion of the window glass 148, there has been a concern that the molding die and the molding injection unit are enlarged and become a large-scale apparatus. Moreover, even if the size and shape of the window glass are the same or similar, the mounting position and pitch of the holder 149 may be different if the vehicle type is different. Various types of molds had to be prepared in advance. For this reason, the equipment cost is further increased, and it takes a lot of work to replace and manage the molds. As a result, the burden on the worker increases, and it is difficult to cope with small-lot production of various products. .

  Further, since the upper edge of the window glass 148 is fixed, injection molding is performed on the lower edge portion of the window glass 148, so that a large pressure is applied in the surface direction of the window glass 148. In particular, since the plurality of holders 149 are formed at the same time, the pressure applied to the window glass 148 is considerably high. For this reason, even if the window glass 148 is not damaged, the window glass 148 may be bent or deformed during the injection, and the position of the lower edge portion of the window glass 148 is changed. This was a factor that deteriorated the mounting accuracy.

  Therefore, in view of the above situation, the present invention can injection-mold a resin holder on the lower edge of the glass plate without increasing the equipment, and the molding positions and intervals of the plurality of resin holders can be reduced. It is an object of the present invention to provide an apparatus for manufacturing an automotive window glass unit that can easily cope with various types of window glass and that can suppress deformation of a glass plate during injection.

An apparatus for manufacturing an automotive window glass unit according to the present invention includes: a glass plate for an automobile window, and a plurality of resin holders that are integrally formed with a lower edge portion of the glass plate, A manufacturing apparatus for manufacturing a window glass unit for an automobile connected to a lifting device for lifting and lowering a plate via the resin holder,
A glass receiver for fixing the glass plate in a specified position;
A plurality of molds in which a cavity corresponding to the resin holder is formed inside by sandwiching a lower edge portion of the glass plate fixed by the glass receiver,
An injection unit for injecting molten resin into the mold;
An injection position displacement mechanism that moves the injection unit along a straight line connecting the plurality of molding dies, and allows the resin to be sequentially injected into the plurality of molding dies;
A mold moving mechanism that enables at least one of the plurality of molds to move along the lower edge of the glass plate.

  Here, the shape of the “resin holder” is not particularly limited. For example, the front-side holding portion whose inner surface abuts on the surface of the glass plate and the back-side holding portion whose inner surface abuts on the back surface of the glass plate And an end surface side holding part that connects the front side holding part and the back side holding part with the inner surface contacting the lower edge end face of the glass plate, and a protruding connecting part that protrudes downward from the end face side holding part and is connected to the lifting device. Can be configured. Also, the configuration of the “elevating device” is not particularly limited, but there are two arms connected to each other so as to be pivotable about a fulcrum, and a lifting rail slidably attached to their upper ends. The fixed rail is slidably attached to the lower end of one arm, and the regulator is connected to the lower end of the other arm via a rack gear. In this case, the resin holder is connected to the lifting rail, but a connecting nut may be embedded in the resin holder.

  In addition, the “automobile window glass unit” includes at least a glass plate and a plurality of resin holders, but members other than these may be attached. Further, the “glass receiver” may be fixed in a state where the glass plate is erected, or may be fixed in a state where it is laid down. The structure for fixing the glass plate is not particularly limited.For example, the receiving body that can be placed in a state in which the glass plate is laid, and the reference position of the glass plate in contact with the upper edge of the glass plate. It can be constituted by a reference pin to be defined and a positioning pin that presses the lower edge of the glass plate and biases the glass plate toward the reference pin.

  Furthermore, the “injection position displacement mechanism” is configured so that an injection unit support (specifically, a guide rail) that supports the injection unit so as to be slidable along a predetermined straight line, and the injection unit face each molding die. And a drive source (specifically, an electric motor) that moves along a straight line. The “mold moving mechanism” is a mold support section (specifically, a feed screw) that slidably supports the mold along the lower edge of the glass plate, and slides the mold by manual operation. It can consist of a handle. Instead of manual operation, a drive source such as an electric motor may be provided, and the mold may be moved using electrically generated power.

  According to the automobile window glass unit manufacturing apparatus of the present invention (hereinafter referred to as “glass unit manufacturing apparatus”), first, the glass plate is fixed at a specified position by the glass receiver, and then, on the lower edge portion of the glass plate. On the other hand, a plurality of molds are mounted. In addition, you may make it provide the mechanism which sends in a shaping | molding die (for example, between an upper mold | type and a lower mold | type), fixing a glass plate to a glass receptacle, In this case, a glass receptacle and a shaping | molding die Can be arranged apart from each other.

  Moreover, a shaping | molding die is provided separately with respect to the site | part by which the resin holder is shape | molded of the lower edge part of a glass plate, respectively. That is, when two resin holders are molded, two sets of molds are attached to the lower edge portion of the glass plate. In addition, the manufacturing apparatus is provided with a mold moving mechanism, and at least one of the plurality of molds can be moved along the lower edge of the glass plate. For this reason, even if it is a case where the various window glass units from which the space | interval and attachment position of several resin holders mutually differ are manufactured, it becomes possible to respond | correspond easily by a shaping | molding die moving mechanism. That is, it is possible to place the mold at a desired position by simply sliding the mold without changing the mold.

  After a plurality of molds are mounted on the lower edge portion of the glass plate, the molten resin is injected into the cavity in the mold by the injection unit. In particular, the manufacturing apparatus is provided with an injection position displacement mechanism, and the injection unit moves along a straight line connecting a plurality of molding dies, and injects resin into the plurality of molding dies in order. That is, a plurality of resin holders are formed one by one in order. For this reason, it is possible to cope with a relatively small injection unit, and it is possible to reduce the size and cost of the apparatus. Further, since the resin holders are molded one by one, it is possible to reduce the pressure applied to the lower edge end surface of the glass plate during injection, and it is possible to suppress the deformation of the glass plate.

Further, in the glass unit manufacturing apparatus of the present invention, “the injection position displacement mechanism includes an injection unit support portion that slidably supports the injection unit along the straight line, and the injection unit is attached to each of the molding dies. An injection position displacement drive source that moves along the straight line so as to face each other;
The mold moving mechanism includes a mold support portion that slidably supports the mold along the lower edge of the glass plate, and a manual operation unit that slides the mold by manual operation. You may comprise.

  According to the glass unit manufacturing apparatus of the present invention, when the injection position displacement drive source operates, the injection unit slides while being guided by the injection unit support portion. That is, since it becomes possible to move to the position which opposes each shaping | molding die using motive power, such as an electric motor, it can be moved smoothly without imposing a burden on an operator. On the other hand, since the mold is slid by the operation of a manual operation unit (for example, a handle), the interval between the resin holders can be adjusted steplessly. In addition, since a drive source such as an electric motor is not required, the manufacturing apparatus can be further reduced in price and the entire apparatus can be reduced in size and weight.

Moreover, in the glass unit manufacturing apparatus of the present invention, “the glass receiver is
A receiver body that can be placed with the glass plate laid down;
A reference pin that contacts the upper edge of the glass plate and defines a reference position of the glass plate;
A positioning pin that presses the lower edge of the glass plate and biases the glass plate toward the reference pin;
At least when the resin is injected into any of the molds by the injection unit, the glass plate is sucked toward the receiving body and the suction means for preventing the glass plate from being deformed in the surface direction ”is provided. You may comprise.

  Here, only one “reference pin” and “positioning pin” may be provided. However, if a plurality of “reference pins” and “positioning pins” are provided, they can be stably fixed.

  According to the glass unit manufacturing apparatus of the present invention, a receiving body that can be placed in a state in which the glass plate is laid, a reference pin and a positioning pin are provided, the reference pin abuts on the upper edge of the glass plate, The positioning pin urges the lower edge of the glass plate toward the reference pin so that the glass plate is positioned. That is, the glass plate of the window glass for automobiles is generally manufactured based on the upper edge, and a tolerance of about 1 mm occurs in the height method, but in the present invention, the glass plate is biased toward the reference pin side by the positioning pin. Even if the height of the glass plate varies, it is possible to fix the glass plate in a restricting position based on the upper edge. In addition, when injecting the resin into the mold, the glass plate is sucked by the suction means toward the receiving body, so that even if excessive pressure is applied to the lower edge of the glass plate, the glass plate It is possible to prevent lifting due to deformation.

In the glass unit manufacturing apparatus of the present invention, “the molding die is positioned below the glass plate and supported in a fixed state, and the upper die is positioned above the glass plate and can be moved up and down. And consist of
The glass receiver further includes a glass insertion mechanism for inserting a lower edge portion of the glass plate between the upper mold and the lower mold while the glass plate is fixed by the reference pin and the positioning pin.
The glass insertion mechanism includes a pin elevating part that elevates and lowers the positioning pin in pressure contact with a lower edge of the glass plate, a glass driving unit that moves the glass plate in a horizontal direction toward the mold, and When the glass driving unit is operated in a state where the lower edge portion of the glass plate is lifted by the pin elevating unit, and the lower edge portion of the glass plate is inserted between the upper mold and the lower mold, And a glass mounting control means for lowering the lower edge portion of the glass plate and bringing the glass plate into contact with the lower mold ”.

  According to the glass unit manufacturing apparatus of the present invention, the receiver body is separated from the mold, and the glass plate fixed by the reference pin and the positioning pin on the receiver body is moved by the glass insertion mechanism, and the glass The lower edge portion of the plate is inserted between the upper mold and the lower mold. At this time, the glass insertion mechanism first raises the positioning pin in a state of being pressed against the lower edge of the glass plate. That is, the lower edge portion of the glass plate is lifted. Thereafter, the glass driving unit is operated, and the lower edge portion of the glass plate is inserted between the upper mold and the lower mold. Thereafter, the lower edge portion of the glass plate is lowered by the positioning pin, and the glass plate is brought into contact with the upper surface of the lower mold. Thus, even if the lower mold is arranged in a fixed state, it becomes possible to insert the glass sheet while avoiding contact between the lower edge portion of the glass sheet and the lower mold, and consequently the lower edge end surface of the glass sheet. It becomes possible to prevent breakage of. In particular, since the lower edge portion is lifted using the positioning pin, it can be realized at a low cost with a relatively simple configuration.

Moreover, in the glass unit manufacturing apparatus of the present invention, “with the glass receiver placed on and supported by the upper surface, further comprising a receiver support base having a caster at the lower end,
A glass support device configured to include the glass receiver and the support support base, and a molding configured to include the mold, the injection unit, the injection position displacement mechanism, and the mold movement mechanism. The machine may be connected to each other so as to be separable from each other.

  According to the glass unit manufacturing apparatus of the present invention, the glass receiver is placed on the receiver support base having casters, and these are formed into a molding machine (that is, a molding die, an injection unit, an injection position displacement mechanism, And a molding machine having a mold moving mechanism). For this reason, for example, when the shape and size of the glass plate change, the glass support can be replaced with the support support base, and the burden on the operator in the replacement work can be reduced. In other words, it is possible to cope with even a large variety and small volume production relatively easily.

Further, in the glass unit manufacturing apparatus of the present invention, “the resin holder includes a front side holding portion whose inner surface is in contact with the front side of the glass plate and a back side holding portion whose inner surface is in contact with the rear side of the glass plate. And an end surface side holding portion that contacts the lower edge end surface of the glass plate and connects the front surface side holding portion and the back surface side holding portion, and a protrusion that protrudes downward from the end surface side holding portion and can be connected to the lifting device. A connecting portion,
The molding die includes a front side molding part that internally forms a front side cavity corresponding to the front side holding part, a back side molding part that internally forms a back side cavity corresponding to the back side holding part, An end surface side molding portion that internally forms an end surface side cavity corresponding to the end surface side holding portion, and a projecting molding portion that internally forms a projecting cavity corresponding to the projecting connection portion,
The said end surface side shaping | molding part opposes the end surface of the said largest glass plate in the said end surface side shaping | molding part, when the tolerance of the height direction in the said glass plate is considered and the largest glass plate with the largest height is assumed. The part is formed so as to contact the end surface of the maximum glass plate or to create a gap between the end surface of the maximum glass plate,
On the other hand, on the left and right sides of the mold,
When the resin is injected into the mold by the injection unit, a gap formed between the lower edge end surface of the glass plate and the end surface side molding portion is brought into contact with the lower edge end surface of the glass plate. It further comprises an outflow prevention member that closes the opening and prevents the resin that has passed through the gap between the lower edge end surface of the glass plate and the end surface side molding portion from flowing out of the mold ”. May be.

  According to the glass unit manufacturing apparatus of the present invention, the molding die is formed with the front surface side molding portion, the back surface side molding portion, the end surface side molding portion, and the protruding molding portion, and the resin in the cavity in the molding die. By injecting, from the surface side holding part that contacts the front side of the glass plate, the back side holding part that contacts the back side, the end face side holding part that contacts the lower edge end surface and connects the front side holding part and the back side holding part A resin holder having a substantially U-shaped section and a projecting connecting portion projecting downward from the end face side holding portion is formed.

  By the way, when the end surface side holding portion is formed by the end surface side molding portion of the mold, it is necessary to bring a portion of the end surface side molding portion facing the end surface of the glass plate into contact with the end surface of the glass plate. However, as described above, the glass plate for automobile window glass has manufacturing tolerances and is manufactured based on the upper edge, and therefore the position of the lower edge portion with respect to the upper edge may vary. For this reason, according to the size of the glass plate on the design, when the end surface side molding part of the mold is arranged at the lower edge portion of the glass plate, when the height dimension of the glass plate is smaller than the reference value, There may be a gap between the end surface side molding portion and the lower edge of the glass plate, and the resin injected into the end surface side cavity may flow out through this gap. On the other hand, when the height dimension of the glass plate is larger than the reference value, there is a concern that the end surface side molded portion of the mold overlaps with the lower edge portion of the glass plate and the glass plate is damaged.

  On the other hand, in the present invention, the maximum glass plate having the maximum height direction tolerance in the glass plate is assumed, and the portion facing the end surface of the maximum glass plate in the end surface side molding portion is in contact with the end surface of the maximum glass plate. The end surface side molding portion is formed so as to be in contact with each other or to have a gap with the end surface of the largest glass plate. For this reason, even if the dimension of the height direction in a glass plate varies, it becomes possible to avoid the collision with the end surface side shaping | molding part of a shaping | molding die, and the lower edge part of a glass plate. A pair of outflow prevention members independent of the mold are provided on the left and right sides of the mold, and when the resin is injected into the mold by the injection unit, the outflow prevention member is attached to the lower edge of the glass plate. Abut on the end face. According to this, the opening part of the clearance gap formed between the lower edge end surface of a glass plate and an end surface side shaping | molding part is block | closed, and it can prevent that the resin which passed the clearance gap flows out of a shaping | molding die. .

  Further, in the glass unit manufacturing apparatus of the present invention, “when the resin is injected into the molding die, between the front side molding part and the surface of the glass plate, and the back side molding part and the glass A configuration may be adopted in which a gap is formed between the back surface of the plate and the resin so that the resin injected by the injection unit does not flow out.

  By the way, the tolerance of the glass plate occurs not only in the height dimension but also in the thickness dimension, but the tolerance of the thickness dimension is smaller than the tolerance of the height dimension. Therefore, according to the glass unit manufacturing apparatus of the present invention, when the resin is injected into the interior, between the front surface side molded portion and the surface of the glass plate, and between the back surface side molded portion and the back surface of the glass plate, The front side molding part and the back side molding part are formed so that a small gap (a gap where the resin does not flow out due to the viscosity of the resin (for example, 0.1 to 0.2 mm)) is generated. For this reason, even if the thickness dimension of the lower edge part in the glass plate varies, it is possible to prevent the resin from flowing out and to prevent the glass plate from being damaged.

By the way, the glass unit manufacturing apparatus of this invention can also be comprised as follows. That is, “a glass plate for an automobile window and two resin holders formed integrally with a lower edge portion of the glass plate, and the lifting device for raising and lowering the glass plate is made of the resin A manufacturing apparatus for manufacturing an automotive window glass unit connected through a holder,
Two sets of glass receivers for fixing the two glass plates separately to a prescribed position;

An injection position displacement mechanism for moving the injection unit along a straight line connecting the four sets of the molds, and allowing the resin to be sequentially injected into the four sets of molds;
The four sets of molds may be separately provided with a mold moving mechanism that supports the molds so as to be movable along the lower edge of the glass plate.

  According to the glass unit manufacturing apparatus of the present invention, it is possible to manufacture an automobile window glass unit in which two resin holders are formed in units of two. That is, two sets of glass receivers are provided, and two sets of molding dies are arranged on the lower edge portion of each glass plate fixed to each glass receiver. However, there is only one set of injection units, which move along a straight line connecting the four molds, and inject the resin sequentially into the four sets of molds. In addition, until the resin holder is molded with respect to one glass plate, the step of closing the molding die, the step of moving the injection unit to one molding position, the step of injecting the resin into the opposing molding die, The process of moving the injection unit to the other molding position, the process of injecting resin into the opposing mold, the cooling process, the process of opening the mold, the process of ejecting the product, etc. are performed. Using this, it is possible to have an operator inspect and take out a glass plate (finished product) manufactured with the other glass receiver and set a new glass plate, etc. The injection units can be operated alternately and continuously with respect to the respective glass plates fixed to the two sets of glass receivers, and the operating rate of the manufacturing apparatus can be increased.

  Thus, according to the automobile window glass unit manufacturing apparatus of the present invention, since the injection unit can be moved and a plurality of resin holders are formed one by one, the glass plate can be manufactured without making a large facility. A resin holder can be injection-molded on the lower edge. Moreover, the pressure added to a glass plate can be suppressed and the deformation | transformation of the glass plate during injection | emission can be suppressed. Furthermore, since the plurality of molding dies are separately provided and movable, it is possible to easily cope with various types of window glass having different molding positions and intervals of the resin holder.

  On the other hand, as shown in FIG. 1, the molding machine 21 is disposed in a rectangular parallelepiped base 50 and sandwiches a lower edge portion of the glass plate 2 fixed by a glass receiver 25, thereby holding a resin holder inside. 3, four sets of molds 51 in which cavities corresponding to 3 are formed, an injection unit 52 for injecting a molten resin (polyacetal resin or the like) into each mold 51, and four units of the molds 51. The injection position displacement mechanism 53 that allows the resin to be sequentially injected into the plurality of molds 51 and the four sets of molds 51 are separately provided along the lower edge of the glass plate 2. And a mold moving mechanism 54 that is movable.

  More specifically, as shown in FIG. 6, the mold 51 includes a lower mold 57 that is positioned below the glass plate 2 and fixedly attached, and an upper that is positioned above the glass plate 2 and can be moved up and down. It consists of a mold 56. That is, when the upper mold 56 is raised, the mold 51 is opened and the glass plate 2 can be inserted and removed. On the other hand, when the upper mold 56 is lowered and is brought into contact with the lower mold 57 with the glass plate 2 interposed therebetween, The mold 51 is closed and the resin can be injected into the inside. As shown in FIG. 3, the upper mold 56 is connected to a mold clamping unit 69 having a mold opening / closing cylinder 68 disposed behind the mold 51 so that, for example, a pressure of 10 tons is applied by hydraulic pressure. It has become.

  Further, as shown in FIG. 6, the upper die 56 is provided with a surface side molding portion 59 in which a surface side cavity 58 corresponding to the surface side holding portion 7 of the resin holder 3 is formed. Is provided with a back side molding part 61 in which a back side cavity 60 corresponding to the back side holding part 9 is formed. Further, at the communicating portion of the upper die 56 and the lower die 57, an end surface side molding portion 63 in which an end surface side cavity 62 corresponding to the end surface side holding portion 11 is formed, and a protruding cavity 64 corresponding to the protruding connecting portion 12 are provided. A protruding molded portion 65 formed inside is provided. Further, the upper die 56 is formed with an injection port 66 through which the resin is injected by the injection unit 52 and a resin supply path 67 for supplying the resin injected into the injection port 66 to the respective cavities.

  By the way, when the end surface side holding portion 11 is formed by the end surface side molding portion 63, the portion facing the lower edge end surface 10 of the glass plate 2 in the end surface side molding portion 63 is contacted with the lower edge end surface 10 of the glass plate 2. It is necessary to make contact. However, since the glass plate 2 has manufacturing tolerances and is manufactured based on the upper edge, the position of the lower edge end face 10 may vary. For this reason, when the end surface side molding part 63 is arranged on the lower edge portion of the glass plate 2 in accordance with the size of the designed glass plate 2, when the height dimension of the glass plate 2 is smaller than the reference value, There is a possibility that a gap is generated between the end face side molding portion 63 and the lower edge end face 10 of the glass plate 2 and the resin injected into the end face side cavity 62 may flow out through the gap. On the other hand, when the height dimension of the glass plate 2 is larger than the reference value, there is a concern that the end surface side molded portion 63 and the lower edge portion of the glass plate 2 collide and damage the glass plate 2.

  Therefore, in the present example, as shown in FIGS. 8A and 8B, the maximum glass plate having the maximum tolerance in the height direction in the glass plate 2 is assumed, and the maximum glass plate in the end surface side molding portion 63 is assumed. The end surface side molding portion 63 is formed such that a portion facing the end surface is in contact with the lower edge end surface 10 of the largest glass plate or a gap 70 is formed between the lower edge end surface 10 of the largest glass plate. Yes. For this reason, even if the dimension of the height direction in the glass plate 2 varies, it becomes possible to avoid the collision with the end surface side shaping | molding part 63 and the lower edge part of the glass plate 2. FIG. In addition, a pair of outflow prevention members 71 that operate independently of the mold 51 are provided on the left and right sides of the mold 51, and when the resin is injected into the mold 51 by the injection unit 52, The prevention member 71 is brought into contact with the lower edge end surface 10 of the glass plate 2. For this reason, the opening part of the clearance gap 70 formed between the lower edge end surface 10 of the glass plate 2 and the end surface side shaping | molding part 63 is block | closed, and the resin which passed the clearance gap 70 flows out of the shaping | molding die 51 outside. Can be prevented. Further, the outflow prevention member 71 is provided with a buffer member 72 (elastic member) so that the impact when the outflow prevention member 71 contacts the lower edge end surface 10 of the glass plate 2 is reduced. . For this reason, even if the height dimension of the glass plate 2 varies, it is possible to suppress an excessive pressing force from being applied to the lower edge end surface 10 and prevent the lower edge end surface 10 from being damaged. Can be brought into close contact with the lower edge surface 10. In addition, when the gap 70 is provided and the resin is injected as described above, the resin having the arm portion A extending along the lower edge end surface 10 of the glass plate 2 as shown in FIG. A holder 3 is formed.

  Moreover, the tolerance of the glass plate 2 occurs not only in the height dimension but also in the thickness dimension, but the tolerance of the thickness dimension is smaller than the tolerance of the height dimension. Therefore, as shown in FIG. 9, according to the glass unit manufacturing apparatus 1 of the present example, when resin is injected into the interior, between the front surface side molding portion 59 and the front surface 6 of the glass plate 2, and back surface side molding. A gap 74 (for example, 0.1 to 0.2 mm) is formed between the portion 61 and the back surface 8 of the glass plate 2 so that the resin does not flow out. For this reason, even if the thickness dimension of the lower edge part in the glass plate 2 varies, it is possible to prevent the resin from flowing out and to prevent the glass plate 2 from being damaged.

  On the other hand, as shown in FIG. 3, the injection unit 52 includes an injection machine 76 provided with a nozzle 75 at the tip, a screw 77 that melts the resin while rotating and measures a specified amount, and controls the resin at a high temperature by temperature control. And a barrel 78 having a heater (not shown) for maintaining the temperature. The injection position displacement mechanism 53 supports the injection unit 52 and also supports an injection unit support 80 that is slidably supported along a straight line connecting the four sets of molding dies 51, and the injection unit 52 is a molding die. And a servo motor 81 that moves the injection unit 52 along a straight line so as to face the 51, and the injection unit support portion 80 includes two guide rails 82 arranged in the horizontal direction, and a guide rail 82. And a plurality of sliding members 83 capable of reciprocating linear movement by a servo motor 81. Here, the servomotor 81 corresponds to the injection position displacement drive source of the present invention.

  The mold moving mechanism 54 has a feed screw (not shown) and the like, and a mold support part 90 that supports each mold 51 slidably along the lower edge of the glass plate 2 and each feed screw. Four handles 91 are provided for sliding the mold 51 separately by rotating by manual operation. That is, the position and interval of the mold 51 can be adjusted steplessly by a manual operation without using a drive source such as an electric motor. Here, the handle 91 corresponds to the manual operation unit of the present invention.

  The glass unit manufacturing apparatus 1 includes a control box 95, an operation switch 97, an area sensor 98, and the like in addition to the above mechanism. The control box 95 performs various settings and control of the glass unit manufacturing apparatus 1, and includes a monitor touch panel and a plurality of switches. The operation switch 97 includes an operation switch 96 (see FIG. 10) for instructing the start of the molding operation, and buttons for opening and closing the mold clamping. Further, the area sensor 98 is provided with an area sensor 98 that detects whether or not an operator or the like has entered the corresponding area during the molding operation, and interrupts the molding process if the worker or the like has entered.

  Next, a functional configuration of the control device of the glass unit manufacturing apparatus 1 will be described based on the block diagram of FIG. The control device of the glass unit manufacturing apparatus 1 includes an operation control unit 100 that performs a series of operations. The operation control means 100 includes a central information processing device (CPU) that performs calculation and control, and an auxiliary storage device that includes a read-only memory (ROM) and a random access memory (RAM), and according to a program that is input in advance. The resin holder 3 is molded. An operation switch 97 such as an operation switch 96 and a position detection sensor 101 that detects the positions of the four sets of the mold 51 and the injection unit 52 are connected to the input port of the operation control means 100.

  At the output port of the motion control means 83, the servo motor 81 is driven to change the position of the injection unit 52 (ie, the injection position), and the position of the injection unit 52 is sequentially opposed to the four sets of molds 51. The injection position control means 102 for controlling the screw, the injection operation control means 104 for controlling the screw 77 and injecting a specified amount of molten resin from the nozzle 75, and the mold opening / closing cylinder 68, thereby opening and closing the mold 51. The mold opening / closing control means 105 is connected. Further, the glass mounting control means 106 is connected to the output port of the operation control means 100. The glass mounting control means 106 sucks and holds the glass plate 2 by the suction means 39 and positions it by the pin moving cylinder 33. The pin 31 is pressed against the lower edge end surface 10 of the glass plate 2 and the glass plate 2 is urged toward the reference pin 29 side. Further, a pin lifting cylinder 35 and a glass insertion cylinder 43 are connected to the glass mounting control means 106, and when the lower end portion of the glass plate 2 is inserted into the forming die 51, the glass plate is moved by the pin lifting cylinder 35. When the lower end portion of the glass plate 2 is operated between the upper die 56 and the lower die 57, the lower edge portion of the glass plate 2 is thereafter moved. Is controlled to bring the glass plate 2 into contact with the lower mold 57.

  Then, the manufacturing method of the window glass unit 4 for motor vehicles by the glass unit manufacturing apparatus 1 is demonstrated based on FIG.4 and FIG.5. First, the operator sets the glass plate 2 on one glass receiver 25 and turns on the operation switch 96. Then, in the glass unit manufacturing apparatus 1, with respect to the glass plate 2 set in the glass receiver 25, a glass insertion process, a mold closing process, a first injection unit moving process, a first injection process, and a second injection unit. A moving process, a second injection process, a cooling process, a mold opening process, and a product ejecting process are sequentially performed. More specifically, first, the lower edge portion of the glass plate 2 is inserted between the upper die 56 and the lower die 57 by the glass insertion mechanism 42 (see FIG. 7) (glass insertion step). Next, the pair of upper molds 56 is lowered, the lower edge portion of the glass plate 2 is sandwiched between the upper mold 56 and the lower mold 57, and pressurized by the mold opening / closing cylinder 68 (molding mold closing step). Thereafter, the injection unit 52 is moved so as to face one of the pair of molds 51 (F1) (first injection unit moving step), and the resin melted with respect to the mold 51 (F1) Is injected (first injection step). Subsequently, the injection unit 52 is moved again so as to face the other mold 51 (F2) (second injection unit moving step), and molten resin is injected into the mold 51 (F2) ( Second injection step). Next, the resin injected into the mold 51 (F1, F2) is cooled (cooling process), and then the upper mold 56 is raised to open the mold 51 (molding mold opening process). Finally, the glass plate 2 on which the resin holder 3 is molded is discharged to the outside of the molding die 51 so that it can be taken out (product ejection step). That is, the completed automobile window glass unit 4 can be taken out.

  In addition, an operator inspects the window glass unit 4 for motor vehicles manufactured in the other glass receiver 25 using the time when these processes are performed, and takes it out. Further, a new glass plate 2 is set in the empty glass receiver 25 and the operation switch 96 is turned on. That is, the molding process is alternately performed on the two glass plates 2, and during the molding of the resin holder 3 on the one glass plate 2, the finished product is taken out and a new glass plate 2 is set. For this reason, the injection units 52 can be operated alternately and continuously, and the operating rate of the manufacturing apparatus can be increased.

  Thus, according to the glass unit manufacturing apparatus 1 of this example, since the injection unit 52 can be moved and the plurality of resin holders 3 are formed one by one, the glass plate 2 can be formed without increasing the equipment. The resin holder 3 can be injection-molded with respect to the lower edge portion. Moreover, since the pressure added to the glass plate 2 is suppressed compared with the case where the two resin holders 3 are simultaneously molded, deformation of the glass plate 2 during injection can be suppressed. Particularly, since the injection unit 52 slides by the operation of the servo motor 81, it can be moved smoothly without placing a burden on the operator.

  Moreover, according to the glass unit manufacturing apparatus 1 of the present example, the molding die moving mechanism 54 is provided, and the four sets of molding dies 51 can be moved separately. For this reason, even if it is a case where the various window glass units 4 for motor vehicles from which the space | interval and attachment position of the two resin holders 3 differ mutually, it can respond easily by the shaping | molding die moving mechanism 54. FIG. That is, even if the molding die 51 is not replaced, it is possible to place the molding die 51 at a desired position simply by sliding the molding die 51. In particular, since the mold 51 slides by manual operation with the handle 91, the interval between the resin holders 3 can be adjusted steplessly. In addition, since a drive source such as an electric motor is not required, the manufacturing apparatus can be further reduced in price and the entire apparatus can be reduced in size and weight.

  Moreover, according to the glass unit manufacturing apparatus 1 of this example, when injecting the resin into the mold 51, the glass plate 2 is sucked by the suction means 39. Even when pressure is applied, it is possible to reliably prevent lifting due to deformation of the glass plate 2.

  Moreover, according to the glass unit manufacturing apparatus 1 of this example, the glass insertion mechanism 42 raises the positioning pin 31 to raise the lower edge portion of the glass plate 2 between the upper die 56 and the lower die 57. Therefore, the glass plate 2 can be inserted while avoiding contact between the lower edge portion of the glass plate 2 and the lower mold 57. Accordingly, it is possible to prevent the lower edge end face 10 of the glass plate 2 from being damaged. Further, since the lower edge portion is lifted using the positioning pin 31, it can be realized at a low cost with a relatively simple configuration.

  Further, according to the glass unit manufacturing apparatus 1 of the present example, the glass receiver 25 is placed on the receiver support base 26 having the casters 47, and these can be separated from the molding machine 21. Therefore, when the shape or size of the glass plate 2 changes, the glass support 25 can be replaced together with the support support base 26, and the burden on the operator in the replacement work can be reduced. .

  Moreover, according to the glass unit manufacturing apparatus 1 of this example, the largest glass plate is assumed and the part facing the lower edge end surface of the largest glass plate in the end surface side molding part 63 abuts on the lower edge end surface of the largest glass plate. Alternatively, since the end surface side molding portion 63 is formed so that a gap 70 is formed between the lower edge surface of the largest glass plate, even if the dimension in the height direction of the glass plate 2 varies, the molding die It becomes possible to avoid the collision between the end face side molding part 51 of 51 and the lower edge part of the glass plate 2. In addition, since a pair of outflow prevention members 71 independent of the mold 51 is provided on both the left and right sides of the mold 51, a gap formed between the end surface of the glass plate 2 and the end surface side molded portion 63. The opening portion of 70 is blocked, and the resin can be prevented from flowing out of the mold 51.

  Furthermore, according to the glass unit manufacturing apparatus 1 of the present example, when the resin is injected into the molding die 51, between the front surface side molding part 59 and the front surface 6 of the glass plate 2, and the back surface side holding part 9 Since a gap 74 is formed between the rear surface 8 of the glass plate 2 and the resin does not flow out, even if the thickness of the lower edge portion of the glass plate 2 varies, the resin plate is prevented from flowing out and the glass plate 2 Can be prevented from being damaged.

  The best mode for carrying out the present invention has been described above, but the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention as described below. Improvements and design changes are possible.

  That is, in the glass unit manufacturing apparatus 1 of the above-described embodiment, the glass plate 2 is formed with the through hole 5 and the resin holder 3 is formed on the portion where the through hole 5 is formed. The resin holder 3 may be formed on the glass plate 2 in which the through hole 5 is not formed. However, if the through hole 5 is provided as in this example, the resin holder 3 can be firmly fixed only by integrating the resin holder 3 with the glass plate 2 by injection molding. Instead of the through hole 5, a recess, a groove, or a recess may be formed, or a protrusion or a raised portion may be provided.

  Moreover, in the glass unit manufacturing apparatus 1 of the said embodiment, although what formed the two resin holders 3 in the lower edge part of the glass plate 2 of one sheet was shown, the number of the resin holders 3 is specifically limited. For example, three or more resin holders 3 may be formed.

  Moreover, in the glass unit manufacturing apparatus 1 of the said embodiment, although two sets of glass receivers 25 were provided and the thing which can manufacture the two window glass units 4 for motor vehicles alternately was shown, the glass receiver 25 is shown. Only one set may be used, and the window glass units 4 for automobiles may be manufactured one by one. However, if two sets of glass receivers 25 and a mold 51 are provided as in the above-described embodiment, the time during which the resin holder 3 is molded with respect to one glass plate 2 is used to Therefore, the injection units 52 can be operated alternately and continuously, and the operating rate of the glass unit manufacturing apparatus 1 can be increased. In particular, since the window glass for the front seat and the window glass for the rear seat having different shapes can be manufactured alternately without exchanging the mold, it is possible to reduce the intermediate stock.

  Furthermore, in the glass unit manufacturing apparatus 1 of the said embodiment, although what showed that the four sets of shaping | molding molds 51 can each be moved separately was shown, Of the two sets of shaping | molding dies 51 corresponding to one glass plate 2, Only one mold 51 may be movable. Even with such a simple configuration, the position of one mold 51 and the pitch of the two molds 51 can be changed.
