Description

  The present invention relates to a trimming apparatus having a cutter that cuts a planar member made of a sheet member or the like affixed to a substrate such as transparent glass. More specifically, the trimming apparatus can improve the operation efficiency and further simplify the replacement work. The present invention relates to a trimming apparatus that can reduce the burden on the cutter and a cutter exchanging apparatus used therefor.

  For example, the photoelectric conversion module has a back sheet (an example of a planar member) attached to one side of a glass substrate via an adhesive layer, and this back sheet is attached to the glass substrate so as to protrude from the periphery of the glass substrate. Then, it cut | disconnected along the glass substrate with a cutter etc., and the excess part which protruded was excised with the adhesive bond layer. In a trimming apparatus for cutting off the surplus portion, a planar member transported along a transport path is conventionally held on a work table composed of a vacuum suction unit and then moved along the planar member. Some have a trimming unit that cuts off the surplus portion of the planar member (see, for example, Patent Document 1). The trimming unit is attached with a cutter made of metal or the like that cuts the planar member as the trimming unit moves.

  The trimming apparatus includes a support moving base that supports the trimming unit so as to be movable in the horizontal direction along the peripheral edge of the substrate, and the peripheral edge of the substrate held on the work table is a predetermined position detecting unit. And the trimming unit is moved by the support moving base under the control based on the detection result. That is, the cutter is moved along the periphery of the substrate, and the planar member is cut by the cutter, so that the sheet member or the like protruding from the substrate, which is an excess of the planar member, is cut off.

  In such a trimming apparatus, when the cutting of the planar member is repeatedly performed, the cutter as a cutting member naturally deteriorates. Therefore, when the above cutter reaches the limit of use, stop the trimming device, remove the cutter attached to the trimming unit, attach a new cutter to the trimming unit, restart the trimming device, and replace the cutter. ing.

  The above replacement work varies depending on the material of the sheet or the cutter and the cutting speed. For example, if the replacement work is performed at a rate of once every two hours, the trimming apparatus according to the replacement work while using the trimming apparatus for one day will be described. The stop time is enormous, which causes a significant reduction in the operating efficiency of the trimming apparatus. Furthermore, this replacement work is complicated, such as manually performed by an operator, and is a heavy burden on the operator.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a trimming device that can improve the operation efficiency, simplify the replacement work, and reduce the burden on the operator, and a cutter replacement device used in the device.

In order to solve the above-described problems, the present invention is described as follows, for example, based on FIGS. 1 to 15 showing an embodiment of the present invention.
That is, the present invention 1 relates to a cutter exchanging apparatus (30) used in a trimming apparatus (1) provided with a cutter (22) for cutting a planar member (6), which relates to a cutter exchanging apparatus used in a trimming apparatus. A storage part (31) capable of storing a plurality of cutters (22), a holding part (32) for holding one of the cutters (22), and pressing the cutter (22) with the holding part (32) The pressing means (33) urged so as to be freely retractable and retracted from the storage portion (31) side between the storage portion (31) and the holding portion (32), and the storage is performed when the storage device is released. A slider (34) that conveys the cutter (22) from the section (31) to the holding section (32), and when the slider (34) is in the forward posture (F), the slider (34) The pressing means (33) forms a flat part (35) for holding the cutter (22), and when the slider (34) is retracted from the forward posture (F), the flat part (35) and the pressing part The cutter (22) held by the pressure means (33) is released.

  The present invention relates to a trimming device, and relates to at least one trimming unit (9) having a cutter (22) for cutting the planar member (6) as it moves, and the trimming unit (9) as a planar member (6). A trimming apparatus (1) having a support moving base (8) for supporting a movable portion in a horizontal direction along a predetermined shape for cutting off an excess portion of the trimming unit (9). The cutter changing device (30) is provided.

  In the present invention 1 or 2, the cutter held by the flat portion and the pressing means is released from the held state when the slider is retracted from the forward posture, and is discharged from the cutter changer by the action of gravity. The The cutter stored in the storage unit is transported to the holding unit when the slider is moved out of the retracted posture, and is held by the flat portion of the slider and the pressing means when the slider is in the advanced posture.

  The slider may be configured to convey one cutter at a time from the storage unit to the holding unit when the slider is moved. For example, the urging means for urging the cutter housed in the housing portion toward the slider is disposed in the housing portion, and the receiving flat surface portion and the blocking flat surface portion are formed on the flat surface portion of the slider in order from the tip. Also good. According to this configuration, the cutter stored in the storage unit is urged toward the slider, the receiving flat part is provided close to the storage part with a thickness width of the cutter, and the blocking flat part is in close contact with the storage part. Therefore, when the slider is in the retracted position, the cutter can be transferred one by one from the storage portion to the receiving flat surface portion, and the cutter is conveyed one by one to the holding portion as the slider moves out. Can do. Further, when the slider is not in the retracted posture, the storage portion and the blocking flat surface portion are brought into close contact with each other, and the cutter can be prevented from falling off from the storage portion.

  The biasing means is not limited to a specific material, shape, or application, and may be any configuration that biases the cutter stored in the storage portion toward the slider. For example, a box that forms a storage portion is provided inside, and an elastic body such as a spring or rubber is provided at the bottom of the box, or a cylinder device that can be moved back and forth, or air is ejected to the bottom of the box. It is good also as a structure which provides a jet nozzle. According to these structures, the cutter accommodated in the accommodating part can be urged | biased toward a slider.

  The cutter may be a tangible one that cuts a planar member, and is not limited to a specific shape or configuration. For example, a locking portion may be formed in the handle portion of the cutter, and a drop prevention bar is provided on the receiving flat portion so as to be urged and retracted to the locking portion so as to lock the locking portion. The holding means is provided on the pressing means so as to move back and forth to the locking portion and lock the locking portion. According to this configuration, when the slider is retracted from the forward movement posture, the cutter locked to the holding stabilization bar is not interlocked with the receiving flat portion due to friction or the like, and the holding portion improves the cutter. Can be released. Further, when the slider is moved out of the retracted posture, the cutter is locked to the fall prevention bar, and the cutter disposed on the receiving plane portion can be prevented from falling. The fall prevention bar is pushed and retracted by the holding and stabilizing bar that is moved when the slider is in the forward posture. In addition, the holding and stabilizing bar is arbitrarily retracted until the slider is retracted and then moves forward.

  Said holding | maintenance stabilization bar is not limited to the thing of the structure to be moved in and out. For example, a locking portion is formed in the handle portion of the cutter, a drop prevention bar is provided on the receiving flat portion to be urged and retracted to the locking portion so as to lock the locking portion, and the locking means is provided with the locking portion. It is good also as a structure which provides the holding | maintenance stable bar which is urged | biased more strongly than the said fall prevention bar so that it can withdraw | emit to / from a part, and latches the said latching part. According to this configuration, the same operation and effect as the configuration in which the holding and stabilizing bar that is moved out and retracted is provided, and the configuration for moving the holding and stabilizing bar in and out is not required, and it is performed relatively inexpensively. Can do. The fall prevention bar is retracted by the holding and stabilizing bar that is more strongly biased when the slider is in the forward posture. Further, the holding stabilization bar is pushed by the cutter and retracted when contacting the cutter conveyed to the slider.

  The pressing means may be configured to be urged so as to be freely retractable. For example, the contact surface of the pressing means that the cutter transported to the slider first contacts the pressing means is transported by the cutter. It is good also as a structure formed in a slope with respect to a direction. According to this configuration, the pressing means that is in contact with the cutter conveyed by the slider is pushed along the slope along with the conveyance of the cutter and is retreated, so that it is retreated relatively smoothly.

  Cutter replacement work performed by moving the slider back and forth is performed by the operator, or by the amount of cutting of the flat member set based on the material of the flat member, cutting speed, etc., or every hour However, for example, a configuration is provided in which a blade break detecting means for detecting a held cutter and a control device for judging an abnormality of the cutter detected by the blade break detecting means and moving the slider back and forth. Also good. According to this configuration, when an abnormality occurs in the cutter, the slider is moved back and forth and the cutter replacement operation is performed. Therefore, the cutter replacement operation can be performed without requiring a complicated operation by an operator.

  The timing of replenishing the cutter stored in the storage unit is determined by visual observation from the small window by providing a small window that allows the storage unit to be visually observed in a box that forms the storage unit. The determination may be made by subtracting the number of times the slider has been retracted from the number of stored cutters in the storage unit. For example, a detection unit that detects the cutter stored in the storage unit, and detection by the detection unit You may judge by providing the control apparatus which alert | reports based on a result. According to this configuration, when there is no cutter in the storage unit, it can be notified that there is no cutter in the storage unit, and for example, if the number of cutters stored in the storage unit is detected, the cutter stored in the storage unit The remaining number can be notified, and the timing for replenishing the cutter to the storage unit can be determined according to these notifications.

  The planar member is not limited to a specific material, shape, or application. For example, it may be a sheet member or the like attached to one surface of the substrate used in the photoelectric conversion module, or may be a thin film such as a heat reflecting film attached to a glass substrate or the like. When the planar member is a sheet member attached to these substrates, the predetermined shape is formed at the peripheral edge of the substrate, and the sheet member is cut while the cutting means moves along the predetermined shape. By doing so, the excess part which protruded from the peripheral edge of this board | substrate is cut off, and the sheet | seat part except the excess part is cut out. The planar member is not limited to a sheet member attached to a substrate, and may be a sheet material such as glass, metal, wood, synthetic resin, cloth, synthetic resin film, paper, Any material that can be cut by the cutting means can be used.

When the planar member is a sheet member attached to a substrate, the sheet member is not limited to a specific structure or material. For example, it may be of a single-layer structure consisting only of an adhesive sheet member, or for improving the weather resistance applied to the surface of the first sheet member having adhesiveness and the first sheet member. It may have a two-layer structure composed of the second sheet member. Specific examples of the material for the sheet member include transparent synthetic resins such as silicon, ethylene vinyl acetate (EVA), and polyvinyl butyral. Moreover, as said 2nd sealing part, there exists a thing of a single sheet | seat structure and a laminated structure, but as a 2nd sealing part of a single sheet | seat structure, fluorine-type resin, such as a brand name Tedlar, polyethylene terephthalate, etc. The second sealing portion of the laminated structure is a laminated sheet obtained by laminating a metal film such as aluminum or a thin film such as SiO _{2 on} one surface of the sheet made of the fluorine resin, polyethylene terephthalate, or the like. Alternatively, a laminated sheet obtained by laminating EVA on both surfaces of an aluminum alloy thin film, a laminated sheet obtained by laminating EVA on PET, or the like may be used.

  Further, the substrate is not limited to transparent glass, but may be formed of metal or other material, or may be a substrate provided with a photoelectric conversion element, an electrode, or the like. These substrates are usually formed in a quadrangular shape, but may be formed with smooth curves such as arcs at the four corners, and may have a curved shape at the periphery, for example, an oval shape. . Further, a chamfered portion may be formed on the substrate along the peripheral edge between the side surface and the adherend surface.

  The predetermined shape can be set to an arbitrary shape other than a quadrangle. For example, the predetermined shape can be set by inputting the predetermined shape to a control unit that controls the trimming unit. However, when the planar member is a sheet member attached to one surface of the substrate, and the excess portion that protrudes from the periphery of the substrate is removed, the periphery of the substrate has the predetermined shape. Therefore, the predetermined shape may be set by measuring the shape of the substrate. For example, a shape detecting means for detecting the shape of the substrate is attached to the trimming apparatus, and the peripheral position of the planar member is detected by the shape detecting means prior to the movement of the trimming unit or the like. Based on the result, the predetermined shape can be set.

  Although it is sufficient that at least one trimming unit is provided, a plurality of trimming units may be attached to one supporting moving table. Further, a plurality of the above-described support moving bases may be provided. For example, one trimming unit may be attached to one support moving base, and two trimming units may be attached to the other support moving base.

  According to the trimming device of the present invention and the cutter changer used therefor, the above-mentioned slider can be moved out and retracted once, so that the cutter can be changed very easily and in a short time, and the cutter replacement work is completed. As a result, the time required for the cutter replacement work can be greatly reduced, the stop time of the trimming apparatus required for the replacement work can be greatly reduced, and the operation efficiency of the trimming apparatus can be improved. Furthermore, complicated replacement work of attaching and detaching the cutter is not required, and the replacement work can be simplified to reduce the burden on the worker.

  Also, according to the trimming device of the present invention and the cutter changer used in this device, the cutter is released when the forward slider is retracted, so that the cutter can be dropped by the action of gravity. As a result, the cutter is ejected from the cutter exchanging device, so there is no need to provide a special configuration for ejecting the used cutter from the cutter exchanging device, and the cutter exchanging device can be implemented at low cost. In addition, by storing a plurality of cutters in the storage unit, the cutters can be replaced continuously a plurality of times without replenishing the storage unit.
