  However, in the conventional apparatus for transferring while heating the work substrate shown in Patent Document 1 or the like, the lower heating plate is composed of one metal plate heated by a heater, and the heated one metal plate is used. Since the work substrate was heated by the radiated heat, when the vertical and horizontal sizes of the work substrate were changed due to technological innovation, etc., each time the work substrate was changed, the size corresponds to the changed work substrate. It was necessary to newly manufacture a single metal plate of vertical and horizontal sizes separately. In that case, the metal plate as described above has to be newly custom-made every time the vertical and horizontal sizes are different, and there is a problem that the manufacturing cost of the conveyor with a heating function increases as a whole.

  In the conventional conveyor with a heating function, the lower heating plate is constituted by one metal plate as described above. Therefore, when the one metal plate is heated by a heater or the like, There has been a problem that deformation such as warping or bending occurs, and as a result, uniform heating of the entire work substrate becomes difficult.

  Moreover, in the above-mentioned conventional conveyor with a heating function, since the lower heating plate is composed of one metal plate as described above, the weight of the lower heating plate is increased. In such a case, there is a problem that it places a heavy burden on the worker.

  Further, in the conventional conveyor with a heating function, the lower heating plate is constituted by one metal plate as described above, so that a large amount of heat is required to heat the one metal plate, There was a problem that a large amount of heater drive power was consumed.

  The present invention has been made paying attention to such problems of the prior art, and in a conveyor with a heating function for transferring a work substrate while heating it for drying or heat treatment, the vertical and horizontal size of the work substrate is changed. The height and width of the conveyor with a heating function to meet the requirements can be changed very flexibly and at low cost, and the entire work substrate being transferred can be uniformly heated. An object of the present invention is to provide a conveyor having a heating function, which can reduce the weight of the operator by reducing the overall weight of the attached conveyor and reduce the power consumption of the entire conveyor with the heating function. .

  A conveyor having a heating function according to the present invention for solving the above problems is a conveyor for moving a glass or resin work substrate (including a roll substrate) in a predetermined moving direction. A support frame extending in parallel with the moving direction, and an aluminum extrudate cut into a predetermined length, each cut surface including a substantially rectangular outer frame, and the inside of which is hollow A plurality of extruded extruded materials, each of which is disposed on the support frame such that each longitudinal direction thereof is orthogonal to the moving direction and each is spaced from each other by a predetermined distance. A plurality of the cut extruded materials and the cut extruded materials, which are respectively disposed between the cut extruded materials and in contact with the lower surface of the work substrate positioned above the cut extruded materials, to move the work substrate. A rotating body for heating, a conveyor having a heating function, and extending in a direction parallel to a longitudinal direction of each of the cut extruded materials in each cavity of each cut extruded material, A plurality of cylindrical pipes are integrally formed, and at least one of the cylindrical pipes is inserted with an elongated heater having a generally elongated shape such as a rod heater, and the cylindrical pipes and the Between the outer frame body, a belt-like connection portion for transferring heat from the elongated heater to the outer frame body is integrally formed.

  Moreover, in the conveyor provided with the heating function according to the present invention, the length of each of the cut extruded materials is in the middle of each of the left and right side plate portions as viewed from the cut surface of the outer frame body of each cut extruded material. It is desirable that a cylindrical pipe extending in parallel with the direction is integrally formed.

  Moreover, in the conveyor provided with the heating function by this invention, each said rotary body is equipped with the rotating shaft extended in the direction orthogonal to the said moving direction, and the roller protrudingly provided in several places of this rotating shaft. An upper cover is provided on the side (upper side) opposite to the work substrate of the gap between the cut extruded materials so as to block the gap above the gap excluding the portion where the roller protrudes. The left and right upper ends as viewed from the cut surface of the outer frame body of each cut extruded material project in a direction perpendicular to the longitudinal direction of each cut extruded material and each cut extruded material It is desirable that the upper cover supporting protruding piece extending in parallel with the longitudinal direction of the material and integrally forming the upper cover supporting protruding piece for placing one end of the upper cover.

  Moreover, in the conveyor provided with the heating function by this invention, the cross-section substantially circle | round | yen for plugging the lower part of the said clearance gap on the side (lower side) opposite to the said work board | substrate of the clearance gap between each said cut extruded material. An arc-shaped lower cover is provided, and the left and right lower ends as viewed from the cut surface of the outer frame body of each cut extruded material project in a direction perpendicular to the longitudinal direction of each cut extruded material. The lower cover supporting protruding piece extending in parallel with the longitudinal direction of each of the cut extruded materials, and the lower cover supporting protruding piece for mounting one end of the lower cover are integrally formed. desirable.

  Furthermore, in the conveyor provided with the heating function according to the present invention, a cut surface cover for closing the opening of each cut surface is attached to each cut surface of each cut extruded material. desirable.

  In the present invention, a extruded extruded material obtained by cutting an aluminum extruded material, which has been generally manufactured at a very low cost, to a desired length, and a rotating body disposed between the extruded extruded materials. And constitutes a conveyor with a heating function. Therefore, according to the present invention, even if it is necessary to change the vertical and horizontal sizes of the conveyor with a heating function because the vertical and horizontal sizes of the work substrate need to be changed due to technological innovations, the above-mentioned aluminum extruded material is used. , And change the length of the cut when the cut extruded plate is formed, and increase or decrease the number of cut extruded plates cut in this way. " The vertical and horizontal sizes of the conveyor with a heating function can be changed simply by performing the above (the above-mentioned extruded material can be manufactured at a very low cost and the cutting operation can be performed at a very low cost). Therefore, according to the present invention, when the vertical / horizontal size of the work substrate is changed, the vertical / horizontal size of the conveyor with the heating function can be changed very flexibly and at low cost to cope with the change. .

  Further, in the present invention, the conveyor with a heating function is configured by “arranging a plurality of cut extruded materials obtained by cutting an aluminum extruded material at a desired length through a predetermined interval”, Since each of the cut extruded plates is heated by an elongated heater, the entire heating mechanism is warped or bent by heat, unlike the case where the heating mechanism of the work substrate is constituted by a single metal plate as in the prior art. Therefore, it is possible to uniformly heat the entire work substrate facing the conveyor with a heating function.

  In particular, in the present invention, the heat of the elongated heater is transferred to the upper side of the outer frame body via the strip-shaped connecting portion, and the heat is radiated from the entire upper surface of the outer frame body to make the work substrate planar. When the work substrate is directly heated by the elongate heater (in this case, only the linear portion of the work substrate facing the elongate heater is heated more strongly than the other portions, so the heating is uneven. The entire work substrate can be heated more uniformly compared to the case of

  Further, in the present invention, one or a plurality of the cylindrical pipes are integrally formed in the cavity of each cut extruded material, and halfway between the left and right side plate portions of the outer frame body of each cut extruded material. When the cylindrical pipe is integrally formed in the portion, at least three or more elongated heaters can be included inside, and the work substrate can be efficiently heated in a planar shape from the upper surface of the outer frame. . Further, when the cylindrical pipe is formed in the middle part of the left and right side plate portions in this way, the heat of the elongated heater is conducted to the upper surface of the outer frame body through the side plate portions, It is not necessary to form a strip-shaped connection part one by one, and the manufacturing cost can be reduced.

  Further, in the present invention, an upper cover supporting protruding piece is integrally formed at each of the left and right upper ends of the outer frame body of each of the cut extruded materials, and each of the cut ends is used by using the upper cover supporting protruding piece. When an upper cover is provided on the side (upper side) facing the work substrate of the gap between the extruded materials to cover the upper side of the gap (a gap excluding the protruding roller portion), Since heat from the elongated heater can be prevented from escaping from the gap, the work substrate can be heated more efficiently.

  Further, in the present invention, a lower cover supporting protruding piece is integrally formed at each of the left and right lower ends of the outer frame body of each of the cut extruded materials, and each of the cut pieces is cut using the lower cover supporting protruding piece. When a lower cover is provided on the opposite side (lower side) of the gap between the extruded materials to the lower side of the gap, heat from the elongated heater escapes from the gap. Since this can be prevented, the work substrate can be heated more efficiently.

  Further, in the present invention, when a cut surface cover is attached to each cut surface of each cut extruded material, heat from the elongated heater can be prevented from escaping from the opening of the cut surface. The work substrate can be heated more efficiently.

  Further, in the present invention, the conveyor with a heating function is configured by “arranging a plurality of cut extruded materials obtained by cutting an aluminum extruded material at a desired length at a predetermined interval”. Therefore, the whole conveyor with a heating function can be reduced in weight, and the burden of the worker at the time of conveyor installation can be reduced.

  Furthermore, in the present invention, the conveyor with a heating function is configured by “arranging a plurality of cut extruded materials obtained by cutting an aluminum extruded material at a desired length at a predetermined interval”. Therefore, the amount of heat required for heating the cut extruded material constituting the conveyor with a heating function can be reduced, and the power consumption for heating by the conveyor with a heating function can be reduced.

  The best mode for carrying out the present invention is a mode as described in Example 1 below.

An upper protruding piece for supporting the upper cover for supporting the upper cover.

  In the first embodiment, a rod-shaped heater (not shown) is provided in one or a plurality of the three tubular pipes 6 and 9 formed integrally with each of the cut extruded materials 1. Has been inserted. In the first embodiment, a rod-shaped heater may be inserted only into the central cylindrical pipe 6 among the three cylindrical pipes 6, 9. You may make it insert a rod-shaped heater in two or all three.

  In the first embodiment, as shown in FIG. 2, a plurality of the cut extruded materials 1 are placed on the support frame 20 arranged so as to extend in parallel with the moving direction of the work substrate (see arrow P). They are arranged in a direction orthogonal to the moving direction P with a predetermined interval therebetween. Further, a roller (described later) is disposed between the cut extruded materials 1.

  FIG. 3 is a partial front view showing a part of a conveyor with a heating function according to the first embodiment using a plurality of the extruded extruded materials 1 and rollers, and FIG. 4 is a partial plan view thereof. 3 and 4, the support frame of FIG. 2 is not shown.

  In the first embodiment, as shown in FIG. 3, a rotary shaft 21 driven by a motor (not shown) between the cut extruded materials 1 and a roller 22 protruding and fixed at a plurality of locations of the rotary shaft 21. Is arranged. As shown in FIG. 3, the roller 22 is disposed so as to protrude above the upper surface of the cut extruded material 1 by a predetermined distance (in a direction approaching the work substrate W).

  Further, in the first embodiment, as shown in FIG. 4, the portion above the gap (space) between the cut extruded materials 1 (on the side of the work substrate W) where the roller 22 does not protrude. For example, a metal plate-like upper cover (lid) 23 for closing the gap is disposed. As shown in FIG. 3, the upper cover 23 is disposed as described above by placing and supporting both end portions on the upper protruding piece 11 of the cut extruded material 1. The upper cover 23 is installed to improve the heating efficiency of the work substrate W so that the heat from the bar heater does not escape from the gap.

  In the first embodiment, as shown in FIG. 3, for example, a metal cross section for closing the lower side (the side opposite to the work substrate W) of the gap (space) between the cut extruded materials 1 is omitted. An arc-shaped lower cover 24 is disposed. As shown in FIG. 3, the lower cover 24 is disposed as described above by placing and supporting both ends of the lower cover 24 on the lower protruding piece 10 of the cut extruded material 1. . The lower cover 24 is installed to improve the heating efficiency of the work substrate W so that the heat from the bar heater does not escape from the gap.

  Moreover, as described above, openings such as the cavity 2 and the cylindrical pipes 6 and 9 are present at both ends of the cut extruded material 1 (each cut surface of the aluminum extruded material) (FIG. 1). Therefore, in the first embodiment, as shown in FIG. 5, for example, a metal cutting surface cover 25 for closing each opening is provided with a screw (not shown) at each end (cutting surface). It is fixed with. The cut surface cover 25 is for improving the heating efficiency of the work substrate W so that the heat from the bar heater does not escape from the openings at both ends (cut surfaces). The cut surface cover 25 is formed with punched holes 25a and 25b for allowing the rod heater to pass through the cylindrical pipes 6 and 9.

  Moreover, Fig.6 (a) is a partial top view which shows a part of conveyor with a heating function by the present Example 1, FIG.6 (b) is the sectional view on the AA line. In the first embodiment, as shown in FIG. 6B, the upper heating plate 26 for heating the upper surface of the work substrate W is arranged side by side above the cut extruded material 1. In FIG. 6B, only one upper heating plate 26 is shown, but actually, a plurality of the upper heating plates 26 are arranged side by side so as to face the entire work substrate W. Yes. The upper heating plate 26 is, for example, a plate-shaped member having a metal interior formed in a cavity, and a bar heater (not shown) is inserted therein.

  Next, the operation of the first embodiment will be described. FIG. 7 is a side view of the first embodiment showing a state when the work substrate W is being transferred (in FIG. 7, the upper heating plate 26 of FIG. 6 is not shown). In the first embodiment, as shown in FIG. 7, the cut extruded materials 1 and the rollers 22 are alternately arranged in parallel with the moving direction P of the work substrate W. And the heat | fever of the rod-shaped heater inserted in the inside of the said cut extruded material 1 is conducted, and it radiates | emits from the upper surface of the said cut extruded material 1 in planar shape. Therefore, according to the first embodiment, a plurality of work substrates W are sequentially transferred by the roller 22 while being heated by the cut extruded material 1. In this case, even when it becomes necessary to change the vertical and horizontal sizes of the work substrate W due to technological innovation, the cutting length of the cut extruded material 1 from the aluminum extruded material is changed and the cut extruded material 1 is cut. By changing the number of arrangements, it is possible to deal with the change very flexibly and inexpensively.

  Next, FIG. 8A schematically shows the heating and transfer operations of the work substrate W according to the first embodiment, and FIG. 8B schematically shows the heating and transfer operations of the work substrate W according to the comparative example. FIG. In FIG. 8A, reference numeral 27 schematically shows a rod heater inserted into each cylindrical pipe 6 or 9 of the cut extruded material 1. When the work substrate W is transferred using the first embodiment, the heat from the rod-shaped heater 27 is transferred to the cut extruded material 1 through the strip-shaped upper connection portion (see reference numeral 7 in FIG. 1) or the like. Since the work substrate W is conducted to the upper surface, the work substrate W is heated in a planar shape from the upper surface of the cut extruded material 1, and the entire work substrate W is heated uniformly. On the other hand, in the comparative example as shown in FIG. 8B, the bar heater 27 is simply arranged between the rollers 22 and the heat from the bar heater 27 is linearly formed on the work substrate. Since only W is heated, there is a risk of uneven heating of the work substrate W (may cause warping or distortion of the work substrate W).

  As described above, in the first embodiment, the cut extruded material 1 and the rollers 22 (and the rotating shaft 21) constitute a conveyor with a heating function, so the vertical and horizontal sizes of the work substrate W are changed. Therefore, even when it is necessary to change the vertical and horizontal sizes of the conveyor with a heating mechanism, the length to be cut when the extruded aluminum sheet is cut to form the cut extruded plate is cut in this way. The vertical and horizontal sizes of the conveyor with heating mechanism can be changed simply by increasing / decreasing the number of the extruded plates 1 that have been cut (in addition, the above-mentioned extruded extruded material can be manufactured at an extremely low cost, and the cutting operation etc. Therefore, the change of the vertical and horizontal sizes of the work substrate W can be handled very easily and at low cost.

  In the present invention, the conveyor with a heating mechanism is configured by arranging a plurality of cut extruded materials 1 each including a bar heater at a predetermined interval, and the heat of the bar heater is the band-shaped heat. Since heat is transferred to the upper plate portion 3 through the upper connection portion 7 and heat is radiated from the entire upper plate portion 3 in a planar shape, the work substrate W is heated in a planar shape. When the workpiece substrate W is directly heated by the rod heater (in this case, only the linear portion of the workpiece substrate W facing the rod heater is heated more strongly than the other portions, so that the workpiece substrate W has uneven heating. Compared to the above, the entire work substrate W can be heated more uniformly.

  Further, in the first embodiment, the cylindrical pipe 6 is integrally formed in the hollow portion 2 and the cylindrical pipe 9 is integrally formed in the middle portion of the side plate portion 5 of each cut extruded material 1. In some cases, three rod heaters are included inside, and the work substrate W can be heated strongly and planarly from the upper plate portion 3 by heat from the three rod heaters.

  Further, in the first embodiment, upper protruding pieces 11 are integrally formed on the left and right upper ends of each of the cut extruded materials 1, and the upper protruding pieces 11 are used to form a space between the cut extruded materials 1. When the upper cover 23 for closing the work substrate W side (upper side) of the gap (excluding the portion where the roller 22 protrudes) is provided, the heat from the rod heater escapes from the gap. Since this can be prevented, the work substrate W can be heated more efficiently.

  Moreover, in the present Example 1, the lower protrusion piece 10 is integrally formed in each right-and-left lower end part of each said cut extruded material 1, and each said cut extruded material 1 is utilized using this lower protrusion piece 10. FIG. When the lower cover 24 is provided to close the gap between the workpiece substrate W and the opposite side (lower side), heat from the bar heater can be prevented from escaping from the gap. The substrate W can be heated more efficiently.

  Furthermore, in Example 1, when the cut surface cover 25 is attached to each cut surface of each cut extruded material 1, the heat from the rod-shaped heater generates an opening (cavity portion 2) of the cut surface. And the pipes 6 and 9 and the like can be prevented from escaping, so that the work substrate W can be heated more efficiently.

  Further, according to the first embodiment, since the conveyor with the heating mechanism is configured by arranging a plurality of the cut extruded materials 1, the entire conveyor with the heating mechanism can be reduced in weight, and the heating mechanism can be reduced. Power consumption for heating the work substrate W by the attached conveyor can be reduced.

  As mentioned above, although each Example of this invention was described, this invention is not limited to what was described as each said Example, A various correction and change are possible. For example, in the first embodiment, only one cylindrical pipe 6 is integrally formed in the cavity 2 of each cut extruded material 1 (of the side plate portion 5 of each cut extruded material 1). Other cylindrical pipes 9 are also formed in the middle portion), but the present invention is not limited to this, and a plurality of cylindrical pipes 6 may be integrally formed in the cavity 2. Good. Conversely, in the first embodiment, one cylindrical pipe 6 is formed in the hollow portion 2 of each cut extruded material 1 and halfway between the left and right side plate portions 5 of each cut extruded material 1. A total of three cylindrical pipes are formed on each of the cut extruded materials 1 by forming a cylindrical pipe 9 in the portion, but the present invention is not limited to this, At least one cylindrical pipe as a whole may be formed on the finished extruded material 1. In the first embodiment, a rod heater is used as the elongated heater inserted into the cylindrical pipe 6 or the like. However, in the present invention, any heater can be inserted into the cylindrical pipe 6 or the like. Of course, for example, a coil-shaped nichrome wire may be formed so as to be elongated so that it can be inserted into the tubular pipe 6 or the like.
