Description

The present invention relates to a spacer mounting device.

In double glazing, a spacer for forming an airtight layer between a pair of glasses is used. The spacers are arranged in a rectangular shape along the four sides of the glass and are sandwiched between a pair of glasses.
In the double glazing production line, before assembling a pair of glasses, a rectangular frame-shaped spacer is attached to the surface of one glass, and the other glass is overlapped with the spacer sandwiched between them to form a double glazing. Is done. Then, in order to automatically perform the process of attaching the spacer to one of the glasses, a spacer attaching device is installed on the production line.

The spacer mounting device includes a spacer transport unit that transports the spacer and a spacer mounting unit that mounts the transported spacer on the surface of the glass.
For example, in the device described in Patent Document 1 or Patent Document 2, a spacer transport unit having a hanging hook on a circulation mechanism such as a belt and a swing arm type that receives the suspended spacer and makes it follow the glass. A spacer mounting unit is used.
The spacer mounting unit is a swing arm type movement that reciprocates between one side and the other side in order to receive the spacer on one side where the spacer transport unit is located and press the spacer against the glass surface on the other side to mount it. The mechanism is adopted. As the swing arm, an opening / closing type annular claw that operates a pair of arcuate members with a cylinder is used so that the spacer does not fall off even if the spacer is gripped and the swing arm rotates.

Since the conventional spacer mounting device described above uses a swing arm type spacer mounting unit, there is a problem that it is difficult to improve the position accuracy when mounting the spacer by pressing it against the surface of the glass.
If the position accuracy of the spacer mounted on the surface of the glass is insufficient, extra work such as correction may occur, which may reduce the work efficiency.
Further, in order to perform the swing arm type spacer delivery operation, the spacer mounting unit requires a complicated mechanism such as an opening / closing type annular claw at the part where the spacer is gripped, and an installation space for these facilities is required. It was.
Further, the spacer mounting unit is mounted on the glass while transporting the spacers one by one by the swing arm, and there is a problem that it is difficult to further improve the work efficiency.

An object of the present invention is to provide a spacer mounting device capable of increasing mounting accuracy, reducing equipment space, and improving work efficiency.

The spacer mounting device of the present invention has a spacer transport unit that transports the spacer and a spacer mounting unit that mounts the transported spacer on the surface of the glass, and the spacer mounting unit vertically supports the glass. It has a support portion, a holding portion capable of holding the spacer while facing the surface of the glass supported by the support portion, and a moving mechanism for moving the holding portion toward the support portion. In the spacer transport unit, the spacer supplied to the side opposite to the support portion of the holding portion is passed over the holding portion and between the holding portion and the glass supported by the support portion. It is characterized by having a transport path for transporting.

In the present invention, by moving the holding portion toward the supporting portion by the moving mechanism of the spacer mounting unit, the spacer held by the holding portion is moved and pressed toward the surface of the glass supported by the supporting portion. The spacer can be attached to the surface of the glass. Since the spacer can be pressed in a state of facing the surface of the glass, the accuracy of the mounting position can be easily improved.
Then, by increasing the accuracy of the mounting position, it is possible to eliminate measures such as correction, and it is possible to improve work efficiency.
Further, since the spacer transport unit uses a transport path that passes above the holding portion when transporting the spacer between the holding portion and the glass supported by the supporting portion, it is a mechanism for introducing the spacer from the side. Compared with this, the flat occupied equipment space can be suppressed to be small.

In the present invention, as the support portion, a frame body or the like that can support the lower side of the glass and the surface opposite to the surface on which the spacer is mounted can be used. For example, an intermediate portion such as a conveyor in a double glazing production line can be used as a support portion. In order to stably support the glass, it is preferable that the vertically placed glass is inclined toward the side supported by the support portion.

In the spacer mounting device of the present invention, the spacer transfer unit is transferred by a first transfer device that transfers the spacer to the side opposite to the support portion of the holding portion and a first transfer device as the transfer path. A first elevating device that raises the spacer, a second transfer device that transfers the spacer raised by the first elevating device in a direction with the support portion via above the holding portion, and the second transfer device. It is preferable to have a second elevating device that lowers the spacer transferred by the transfer device and conveys it between the holding portion and the glass supported by the supporting portion.

In the present invention, a transport path is formed by the first transfer device, the first elevating device, the second transfer device, and the second elevating device, and the spacers are sequentially delivered and conveyed via the upper part of the holding portion to be mounted on the spacers. Can be handed over to the unit.
In particular, by dividing each operation of horizontal transfer and elevating into four devices, the first transfer device, the first elevating device, the second transfer device, and the second elevating device, it is possible to perform parallel processing in each device. It is possible to improve production efficiency by increasing the speed of production tact.
For example, in parallel with the transfer of the spacer by the second transfer device, the spacer can be transferred to the first elevating device by the first transfer device. Alternatively, when the spacer is raised by the first elevating device, the second elevating device is synchronously raised, and when the spacer is lowered by the second elevating device, the first elevating device is synchronously lowered. be able to.

In the present invention, as the first transfer device and the second transfer device, a conveyor or the like provided with a hanging hook on a circulation mechanism such as a belt can be used. Further, as the first elevating device and the second elevating device, those in which a similar hanging hook is attached to a lifting bar that can be raised and lowered can be used. As the lifting mechanism of the hanging bar, existing configurations such as a guide rail and a rack and pinion, a circulation type chain, and a feed screw shaft may be used.
Generally, the surface of the spacer mounted on the glass is coated with a sealing material, a butyl adhesive, or the like for enhancing adhesion, and the hanging hook preferably does not touch the coated surface.

It is preferable that the orientation of the hanging hook in the first transfer device and the second transfer device and the direction in the first elevating device and the second elevating device are opposite to each other. By setting them in opposite directions, the lifting operation of the first lifting device and the second lifting device can be used to smoothly transfer the devices to each other. For example, the spacer can be lifted by the hanging hook of the first lifting device by raising the hanging hook of the first lifting device from below the spacer suspended by the hanging hook of the first transfer device. This allows delivery from the first transfer device to the first elevating device.

In the spacer mounting device of the present invention, it is preferable that the spacer transport unit has an inspection device for inspecting the spacer that is transported by the first transfer device and delivered to the first elevating device.

In the present invention, the specifications, dimensions, types, etc. of the spacer conveyed by the first transfer device can be detected at a stage before being raised by the first elevating device. That is, if an erroneous spacer is sent into the section from the first elevating device, the second transfer device, or the second elevating device, the recovery work such as taking out and replacing the spacer becomes complicated, and the work efficiency is lowered. However, by detecting an erroneous spacer before being lifted by the first elevating device, recovery work can be facilitated and a decrease in work efficiency can be minimized.

In the present invention, as an inspection device for inspecting the spacer, an inspection device for inspecting the specifications, dimensions, types, etc. of the spacer can be used. For inspection, an optical sensor provided in the transport path detects the end of the spacer to identify dimensions and standards, and a camera reads the label or barcode of the spacer to inspect the type.

In the spacer mounting device of the present invention, the spacer mounting unit has a plurality of handlers that are installed in the holding portion to hold a part of the spacer, and the handler is at least one on each of the four sides of the spacer. It is preferable that they are arranged one by one.

In the present invention, since the four sides of the spacer are held by the handlers, the positional accuracy of each side of the spacer mounted on the glass can be improved. For example, when only the upper side of the rectangular frame-shaped spacer is held, both side sides and the lower side of the spacer are not held and may deviate from the original position. However, if each of the four sides is held by a handler, such a deviation can be eliminated. As a result, the work of correcting the position of the spacer attached to the glass can be eliminated, and the work efficiency can be improved.

In the present invention, as the handler, a mechanism for sandwiching each part of the spacer can be used. As the sandwiching configuration, a structure in which the other claw is close to and separated from one claw can be used. At this time, it is desirable not to use the structure in which each part of the spacer is sandwiched in the thickness direction because it touches the surface to which the sealing material, the butyl adhesive, or the like is applied.
The handlers may be arranged along the surface of the frame constituting the holding portion on the holding side. At least one handler may be arranged on each side of the spacer, and a plurality of handlers may be arranged on one side, such as when one side is long.

According to the present invention, it is possible to provide a spacer mounting device capable of increasing mounting accuracy, reducing equipment space, and improving work efficiency.

It has an inclination mechanism for inclining the holding portion 22.
As the feed mechanism, a combination of a guide rail and a drive mechanism such as a rack and pinion, a ball screw shaft, or an air cylinder can be used. As the tilting mechanism, a combination of a rotating mechanism that is supported by the feeding mechanism and rotatably supports the holding portion 22 and a driving mechanism that rotates the rotating mechanism can be used.

In the spacer mounting unit 20, the spacer S4 is moved through the spacer S5 to the state of the spacer S6 (support portion 21) by moving the holding portion 22 by the moving mechanism 23 while the spacer S4 is held by the holding portion 22. It can be attached to the surface of the glass G1 supported by the glass G1).

As shown in FIG. 4, a plurality of handlers 221 to 226 are installed on the surface of the holding portion 22 that holds the spacer S.

Therefore, it is possible to prevent the erroneous spacer S from being sent into the section from the first elevating device 40, the second transfer device 50 to the second elevating device 60. As a result, even if an erroneous spacer S is supplied, the erroneous spacer S can be detected at a stage before the first elevating device 40 is lifted, the recovery work can be easily performed, and the work efficiency can be increased. The decrease can be minimized.

In the present embodiment, since the four sides of the spacer S are held by the handlers 221 to 226 in the holding portion 22 of the spacer mounting unit 20, the positioning accuracy of each side of the spacer S mounted on the glass G1 can be improved. Since the accuracy of the mounting position of the spacer S is improved, the work of correcting the position of the spacer mounted on the glass G1 can be eliminated, and the work efficiency of mounting the spacer can be improved.
