Description

  The present invention relates to an extrusion rear surface equipment provided with a conveyance table for conveying an extruded material extruded from an extruder in an extrusion direction, and an extrusion material manufacturing method using the extrusion rear surface equipment.

  Generally, an extrusion facility for producing an extruded material includes an extruder and an extrusion rear surface facility. The extrusion rear surface equipment includes a conveying table that conveys the extruded material extruded from the extruder in the extrusion direction, a cooling table that cools the extruded material, and the like (see, for example, Patent Documents 1 to 4). The conveyance table includes an initial table and a run-out table that are sequentially arranged in the extrusion direction of the extruded material. The cooling table is arranged on one side of the run-out table.

  The correction table 13 is constituted by a plurality of receiving rollers (not shown) arranged in the length direction and receiving the extruded material 21. On both sides of the correction table 13 in the length direction, stretchers 14 and 14 for correcting the extruded material 21 by tension are arranged as correcting means for correcting the extruded material 21 straight.

  As shown in FIG. 8, the cutting feed table 15 feeds the extruded material 21 to a cutting means 16 that cuts the extruded material 21 into a plurality of predetermined lengths. This feed table 15 is the same as the conventional one. A configuration example of the feed table 15 will be described as follows.

  The feed table 15 is composed of a plurality of feed rollers 15 a that are arranged in the length direction and feed the extruded material 21 to the cutting means 16. As the cutting means 16, a shearing machine, a sawing machine, etc. are used.

  Thus, as shown in FIG. 1, on the left and right sides of the initial table 2a of the transport table 2, the extruded material 21 extruded from the extruder 20 is respectively transferred in the transport direction T of the transport table 2 (that is, the extruded material 21). The guide member 5 for guiding in the direction of extrusion) is arranged. The guide member 5 is configured such that a contact portion with the extruded material 21 is movable together with the extruded material 21 in the extrusion direction (that is, the conveyance direction T of the conveyance table 2). In the first embodiment, a plurality of side guide rollers 3 disposed on both sides of the initial table 2 a are used as the guide members 5.

  Further, a plurality of side guide rollers 3 as guide members 5 are arranged side by side in the conveyance direction T of the conveyance table 2 on both sides of the run-out table 2b of the conveyance table 2 opposite to the cooling table 11 side. Has been. On the other hand, the side guide roller is not disposed on the cooling table 11 side of the run-out table 2b.

  As shown in FIGS. 3 and 4, the side guide roller 3 has a peripheral surface 3 a as a contact portion with the extruded material 21, and is on the upper surface of the transport table 2 (that is, the transport surface of the transport table 2). It is arranged upright. The pitch P between the two side guide rollers 3 and 3 adjacent to each other in the transport direction T of the transport table 2 is, for example, 500 to 1000 mm. As shown in FIG. 4, the lower end position of the peripheral surface 3a of the side guide roller 3 is the same height as the upper surface position of the transport table 2 (that is, the transport surface position of the transport table 2) or a slightly lower height than this. It is arranged in the position. The upper end position of the peripheral surface 3 a of the side guide roller 3 is arranged at a height position higher than the upper surface position of the transport table 2, specifically, half the diameter of a container (not shown) of the extruder 20. It is arranged at the height position.

  The diameter of the side guide roller 3 is set to be equal to the diameter of the transport roller 2z constituting the initial table 2a or the run-out table 2b, specifically, for example, set to 80 to 120 mm.

  A rotation drive device (not shown) is connected to the side guide roller 3. The side guide roller 3 is configured to be driven to rotate in synchronization with the extrusion speed of the extruded material 21 by driving the rotation driving device. More specifically, the peripheral speed of the peripheral surface 3a is It is configured to be rotationally driven so as to be equal to the extrusion speed of the extruded material 21. Further, the rotation direction of the side guide roller 3 (that is, the moving direction of the peripheral surface 3 a) is the forward direction with respect to the conveyance direction T of the conveyance table 2.

  In the present invention, the side guide roller 3 is not driven to rotate but may be rotatable.

  Further, a damage preventing layer 3 b for preventing the extruded material 21 from being damaged by contact with the extruded material 21 is fixed to the peripheral surface 3 a of the side guide roller 3 over the entire circumference. The scratch preventing layer 3b is formed of a felt layer. The felt layer is made of a commercially available heat-resistant material, that is, made of heat-resistant felt, and its surface is flexible. The thickness of the scratch preventing layer 3b is, for example, 5 to 20 mm.

  In the present invention, the scratch preventing layer 3b is not limited to being formed of a felt layer, and may be formed of other members. Further, the damage prevention 3b may be provided on the peripheral surface 3a of the side guide roller 3 so as to be removable.

  Next, the manufacturing method of the extrusion material 21 using the extrusion back surface equipment 1A of the first embodiment will be described below.

  The start end (tip end) of the extruded material 21 extruded from the extruder 20 is held by the puller 8. Further, all the left and right side guide rollers 3 and 3 are rotationally driven. Then, while extruding the extruded material 21 from the extruder 20, the extruded material 21 is pulled by the puller 8 along the conveying table 2 in the extrusion direction at a speed equal to the extrusion speed. As a result, as shown in FIGS. 1 and 5, the extruded material 21 in a high temperature state is transported in the transport direction T of the transport table 2 while sequentially traveling on the initial table 2 a and the run-out table 2 b. The temperature of the extruded material 21 immediately after being extruded from the extruder 20 is, for example, 300 ° C. or higher. Moreover, the cross-sectional shape of the extrusion material 21 is a shape from which the thickness of the right-and-left both sides of the extrusion material 21 mutually differs as shown in FIG. Therefore, the extruded material 21 is easily bent left and right during the initial cooling.

  When the extruded material 21 sequentially travels on the initial table 2 a and the run-out table 2 b, the extruded material 21 is forcibly cooled by the cooling tank 7 and the cooling fan 6. Then, the extruded material 21 is bent and deformed to the left and right, and as a result, the extruded material 21 may come into contact with the peripheral surfaces 3a and 3a of the left and right side guide rollers 3 and 3, as shown in FIGS. However, even when the extruded material 21 comes into contact in this way, the side guide roller 3 is rotationally driven in synchronization with the extrusion speed of the extruded material 21, so that the peripheral surface 3a of the side guide roller 3 is extruded material. 21 and moves in the extrusion direction. Therefore, damage to the extruded material 21 is prevented.

  Then, as shown in FIG. 5, when the extruded material 21 is extruded from the extruder 20 to a predetermined length, the extruded material 21 is cut by a cutting means 9 such as an initial shear in the vicinity of the extruder 20.

  Next, the extruded material 21 thus cut to a predetermined length is continuously pulled onto the run-out table 2b by the puller 8. Thereafter, the extruded material 21 on the run-out table 2b is transferred from the run-out table 2b onto the cooling table 11 by transfer means (not shown) such as lift transfer. Then, as shown in FIG. 6, the extruded material 21 on the cooling table 11 is forcibly cooled by the cooling fan 12.

  Next, when the extruded material 21 on the cooling table 11 is cooled to a predetermined temperature (for example, 10 to 30 ° C.), the extruded material 21 is transferred from the cooling table 11 onto the correction table 13 such as a transfer conveyor (not shown). ). Then, as shown in FIG. 7, the extruded material 21 on the correction table 13 is straightened by the stretchers 14 and 14.

  Next, the straightened extruded material 21 on the correction table 13 is transferred from the correction table 13 onto the cutting feed table 15 by a transfer means (not shown) such as a transfer conveyor. Then, as shown in FIG. 8, the extruded material 21 on the feed table 15 is sent to the cutting means 16. As a result, the extruded material 21 is cut into a plurality of predetermined lengths by the cutting means 16.

  Thus, the extrusion rear surface equipment 1A of the first embodiment has the following advantages.

  That is, since the side guide rollers 3 are arranged as the guide members 5 on the left and right sides of the initial table 2a of the transport table 2, the extruded material 21 falls from the initial table 2a when the extruded material 21 is transported, or the transport table 2 is transported. The extruded material 21 can be reliably guided in the transport direction T of the transport table 2 by the side guide rollers 3 so as not to deviate from the direction T.

  Further, since the side guide roller 3 is also arranged on one side of the run-out table 2b opposite to the cooling table 11 side, the extruded material 21 is transferred to the transport table 2 even when the extruded material 21 travels on the run-out table 2b. It is possible to reliably guide in the transport direction T.

  Of course, since a plurality of side guide rollers 3 are arranged in the transport direction T of the transport table 2, the extruded material 21 can be transported more reliably in the transport direction T of the transport table 2.

  Furthermore, since the side guide roller 3 is rotationally driven in synchronization with the extrusion speed of the extruded material 21, the extruded material 21 can be more reliably guided in the conveyance direction T of the conveyance table 2. Furthermore, when the extruded material 21 comes into contact with the peripheral surface 3 a of the side guide roller 3, the extruded material 21 does not slide on the peripheral surface 3 a of the side guide roller 3, so that the extruded material 21 contacts the peripheral surface 3 a of the side guide roller 3. It is possible to reliably prevent the extruded material 21 from being damaged due to the sliding contact. Moreover, the wear of the peripheral surface 3a of the side guide roller 3 and the scratch-preventing layer 3b provided on the peripheral surface 3a can be reduced, so that the service life of the side guide roller 3 can be extended.

  In addition, since the damage preventing layer 3 b is provided on the peripheral surface 3 a of the side guide roller 3, even if the extruded material 21 comes into contact with the peripheral surface 3 a of the side guide roller 3 when the extruded material 21 is conveyed, the extruded material 21. Can be surely prevented.

  Further, since the side guide roller is not disposed on the cooling table 11 side of the runout table 2b, when the extruded material 21 on the runout table 2b is transferred from the runout table 2b onto the cooling table 11, the extruded material 21 is moved. The extruded material 21 can be easily transferred onto the cooling table 11 without interfering with the side guide rollers.

  Even if the side guide roller 3 is not rotationally driven but rotatable, the same effect as described above can be obtained.

  FIGS. 9-11 is a figure explaining the extrusion back surface installation 1B which concerns on 2nd Embodiment of this invention. The extrusion rear surface equipment 1B of the second embodiment will be described below with a focus on differences from the extrusion rear surface equipment 1A of the first embodiment.

  In the extrusion rear surface equipment 1B of the second embodiment, as shown in FIG. 9, side guide belts 4 are conveyed on the left and right sides of the conveyance table 2 as guide members 5 instead of side guide rollers. A plurality of them are arranged along the direction T. More specifically, a plurality of side guide belts 4 are arranged along the conveyance direction T of the conveyance table 2 on both the left and right sides of the initial table 2 a of the conveyance table 2. Further, a plurality of side guide belts 4 are arranged side by side along the transport direction T of the transport table 2 on one side of the run-out table 2b opposite to the cooling table 11 side. On the other hand, no side guide belt is disposed on the cooling table 11 side of the run-out table 2b.

  The side guide belt 4 is of an endless belt type. That is, as shown in FIG. 10, the side guide belt 4 is wound around two pulleys 4c and 4c that are arranged apart from each other in the transport direction T of the transport table 2 and between the pulleys 4c and 4c. And an endless belt 4b. The side guide belt 4 has a belt surface 4 a of the endless belt 4 b as a contact portion with the extruded material 21.

  Both pulleys 4b and 4b of the side guide belt 4 are arranged upright with respect to the upper surface of the transport table 2 (that is, the transport surface of the transport table 2). The pitch L between the pulleys 4b and 4b is, for example, 80 to 200 mm. In addition, at least one of the pulleys 4b and 4b is driven to rotate. The side guide belt 4 is configured to be driven in synchronization with the extrusion speed of the extruded material 21 by the driving force of the rotationally driven pulley 4b. That is, the belt surface 4a of the endless belt 4b is The side guide belt 4 is configured to move at a speed equal to the extrusion speed. The driving direction of the side guide belt 4, that is, the moving direction of the belt surface a of the endless belt 4 b is the forward direction with respect to the transport direction T of the transport table 2. The gap G between the two side guide belts 4 and 4 adjacent to each other is, for example, 80 to 200 mm.

  The diameter of the pulley 4c is set equal to the conveying roller 2z constituting the initial table 2a or the run-out table 2b, specifically, for example, 80 to 120 mm.

  Further, a damage preventing layer 4 d for preventing the extruded material 21 from being damaged by contact with the extruded material 21 is fixed to the belt surface 4 a of the side guide belt 4 over the entire circumference. The scratch preventing layer 4d is formed of a felt layer. The felt layer is made of a commercially available heat-resistant material, that is, made of heat-resistant felt, and its surface is flexible. The thickness of the scratch preventing layer 4d is, for example, 5 to 20 mm.

  In the present invention, the scratch preventing layer 4d is not limited to being formed of a felt layer, and may be formed of other members. Further, the scratch prevention 4d may be provided on the belt surface 4a of the side guide belt 4 so as to be removable.

  Other configurations of the extrusion rear surface equipment 1B are the same as those of the extrusion rear surface equipment 1A of the first embodiment.

  In the manufacturing method of the extruded material 21 using the extrusion rear surface equipment 1B of the second embodiment, before pulling the extruded material 21 extruded from the extruder 20 by the puller 8, the left and right side guide belts 4, 4 Drive everything. Next, while extruding the extrusion material 21 from the extruder 20, the extrusion material 21 is pulled in the extrusion direction along the transport table 2 by the puller 8. Subsequent steps are the same as those in the first embodiment.

  Thus, the extrusion rear surface equipment 1B of the second embodiment has the following advantages.

  That is, since the side guide belts 4 are arranged as the guide members 5 on the left and right sides of the initial table 2a of the transport table 2, the extruded material 21 falls from the initial table 2a when the extruded material 21 is transported, or the transport table 2 is transported. The extruded material 21 can be reliably guided in the transport direction T of the transport table 2 by the side guide belt 4 so as not to deviate from the direction T.

  Further, since the side guide belt 4 is also arranged on one side of the runout table 2b opposite to the cooling table 11 side, the extruded material 21 can be transferred to the transport table 2 even when the extruded material 21 travels on the runout table 2b. It is possible to reliably guide in the transport direction T.

  Further, since the side guide belt 4 is driven in synchronism with the extrusion speed of the extruded material 21, the extruded material 21 can be guided more reliably in the conveying direction T of the conveying table 2.
