Description

  The present invention relates to a cutting method and apparatus for a plate-like body. More specifically, a second cutting blade is provided in advance in a shearing direction relative to the first cutting blade so as to be movable relative to the first cutting blade. By placing the plate-like body on the placement surface so that the plate-like body as an object to be cut is positioned, by performing relative movement of the second cutting blade, from the plate-like body, The present invention relates to a cutting method of a plate-like body for cutting out a plurality of cut products at the same time, and a plate-like cutting apparatus used for carrying out the method.

In the conventional method for cutting a plate-like body, the placement surface described above is previously formed in a horizontal plane or a substantially horizontal plane (hereinafter simply referred to as a horizontal plane), and the plate-like body is placed on the placement surface composed of the horizontal plane. Then, by executing relative movement of the second cutting blade, a plurality of cut products are cut out simultaneously from the plate-like body.
JP-A-9-295312

  In such a conventional method, since the mounting surface is formed in a horizontal plane, the plurality of plate-shaped bodies are used to mount the plurality of plate-shaped bodies on the mounting surface composed of the horizontal plane. Supply means configured to be able to move the body from the side of the mounting surface in the horizontal direction or substantially horizontal direction (hereinafter simply referred to as the horizontal direction) and send it in (for example, the plate-like body in the horizontal direction) It was necessary to use a cylinder-type pusher that could be pushed freely. In addition, after cutting out the plurality of cut products, the plurality of cut products can be taken out from the side of the mounting surface and carried out to take out the plurality of cut products from the mounting surface. It has been necessary to use unloading means (for example, a suction-type unloading apparatus that can move in the horizontal direction by sucking and supporting the plate-like body) configured to be able to do so. Therefore, before cutting out the plurality of cut products, the appropriate feeding means is driven at an appropriate timing that is a part of the time avoiding the relative movement time of the second cutting blade, and the plurality of sheets After the cut product is cut out, it is necessary to drive the supply means at an appropriate timing which is a part of the time avoiding the relative movement time of the second cutting blade. As a result, in order to properly drive the supply unit and the discharge unit, a certain length of time is wasted in order to take the appropriate timing, and the plate-like body is based on the time wastage. There has been a problem that the productivity of the line for cutting the steel is reduced.

  The present invention has been made paying attention to such a situation, and causes the above-described productivity problem in the conventional method to cause a new problem even when the simultaneous cutting of the plurality of cut products is performed. It aims at providing the apparatus used for implementation of the cutting method of the plate-shaped body which can be eliminated without the method, and the method.

The plate-like body cutting method according to the present invention (hereinafter referred to as the present invention method) is provided in advance with a second cutting blade provided so as to be relatively movable in the shearing direction with respect to the first cutting blade. By placing the plate-like body on the placement surface so that the plate-like body as an object to be cut is positioned thereon, the plate-like body is moved by performing a relative movement of the second cutting blade. A cutting method of a plate-like body that simultaneously cuts a plurality of cut products,
The mounting surface is inclined in advance so as to form an inclination angle that allows the plate-like body to slide down, and so that a plurality of the cut products are taken in the inclination direction. Before the simultaneous cutting of the product, the sliding of the plate-like body on the inclined surface is prevented by a stopper that can receive the lower part of the plate-like body, and after the simultaneous cutting of the plurality of cut products, the stopper by the stopper The state of preventing the sliding state of the plate-like body is released, and the sliding of the upper cut product among the plurality of cut products is prevented for a certain time by the contact of the contact body with the upper cut product during the sliding. It is characterized by doing.

The plate-like body cutting device according to the present invention (hereinafter referred to as the present invention device) is in a state in which a plurality of plate-like bodies as cut objects can be taken from the plate-like body on the first cutting blade. And a second cutting blade is provided so as to be relatively movable in the shearing direction with respect to the first cutting blade, and a plurality of sheets from the plate-like body are provided by relative movement of the second cutting blade. In addition to making the cut product of
The mounting surface is inclined so that a plurality of the cut products can be taken in the inclination direction so as to form an inclination angle at which the plate-like body can slide down, and the plate-like body on the inclined surface is inclined. A stopper capable of preventing sliding before simultaneous cutting is provided, and the upper side of the plurality of cut products after the simultaneous cutting is prevented from sliding down for a certain period of time during the sliding. A contact body that is freely contactable with the cut product is provided above the lower portion of the inclined surface.

  In the method of the present invention having the above characteristics, the mounting surface is previously inclined at the inclination angle, and the plate-like body as the workpiece is placed on the inclined placement surface. Therefore, before cutting out the cut product, the plate-like body is simply positioned above the mounting surface without using the supply means used in the conventional method. The shaped body can be slid down naturally in conjunction with the relative movement of the second cutting blade, and can be moved in a timely manner on the placement surface by the natural slid down. In other words, the plate-like body can be naturally slid down and moved onto the placement surface in a timely manner without driving the supply means with appropriate timing as in the prior art.

  Then, the plate-like body that has moved onto the placement surface is arranged at a cutting position on the placement surface, with the function of the stopper, preventing the sliding off at a predetermined position on the placement surface. It becomes like this.

  Furthermore, after the plate-like body is arranged at the cutting position, the second cutting blade is relatively moved, and after the plurality of cut products are cut out simultaneously, the sliding prevention by the stopper is performed. By releasing the state, the lower cut product among the plurality of cut products can be naturally slid down and sent out from the placement surface. In other words, the lower cut product can be naturally slid down and sent out from the placement surface without driving the carry-out means at an appropriate timing as in the prior art.

  In the process of sending out the lower cut product, the upper cut product of the plurality of cut products is blocked for a certain time during the sliding by the contact of the contact body with the upper cut product. Based on the prevention, the situation where the plurality of cut products are slipped and mixed at the same time to prevent the plurality of cut products from being sent out smoothly is avoided, There is no new problem that a plurality of cut products cannot be sent out smoothly.

  The sending of the upper cut product among the plurality of cut products is smoothly performed by releasing the contact of the contact body with respect to the upper cut product after the lapse of the predetermined time. When the plurality of cut products are three or more, it is preferable to release the contact of the contact body so that the upper cut product delays the sliding.

  Therefore, according to the method of the present invention, even when the simultaneous cutting of the plurality of cut products is performed, the conventional method is used to appropriately time the conventional supply means and the discharge means so as to drive normally. It is possible to eliminate the waste of time without causing new problems, and based on the elimination of the waste of time, the productivity of the line for cutting the plate-like body is improved compared to the conventional case. Therefore, the object of the present invention is achieved.

  Further, according to the device of the present invention having the above characteristics, the method of the present invention having the above characteristics can be carried out with a device having a simple structure in which the contact body is simply provided above the lower portion of the inclined surface. .

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows an apparatus (that is, an apparatus of the present invention) used when carrying out the method of the present invention, and FIGS. 3 to 7 show details of a cutting apparatus constituting the main part of the apparatus. The structure is shown.

  In FIG. 1 and FIG. 5, A is a plate-like body as a cutting object by the cutting device (in this embodiment, a cement-molded plate as a base plate from which a tile material is cut out). The plate-like body A is sequentially fed into a cutting device, which will be described in detail below, one by one. By the cutting device, the peripheral portion and the like are cut into a desired shape shown in FIG. The cut products A1 and A2 are cut out at the same time, and the two cut products A1 and A2 are used to cut the cut product A0 (that is, the cut product A0 taken from the plate A (FIG. 9). In the case of reference)), tiles having a predetermined shape that complement the lacking portion are sequentially generated. The tile material made of the two cut pieces A1 and A2 is called a starter, and as shown in FIG. 10, roofing work is performed using the tile material made of the one piece cut piece A0. It becomes the tile material of the eaves part of the beginning of construction.

  As shown in FIGS. 1 and 3 to 5, the cutting device is configured such that the second cutting blade B <b> 2 is provided to be relatively movable in the shearing direction with respect to the first cutting blade B <b> 1. Yes. The cutting device includes a mounting surface D on which the plate-like body A can be placed so that the plate-like body A is positioned on the first cutting blade B1. By sequentially feeding the plate-like body A so as to place the plate-like body A, the plate-like body A is moved relative to the first cutting blade B1 by executing the relative movement of the second cutting blade B2 to the plate-like body. The two cut products A1 and A2 are cut out from the body A at the same time.

  As shown in FIG. 1, the mounting surface D previously takes two pieces of the cut products A1 and A2 so as to form an inclination angle α that allows the plate-like body A to slide down and in the inclination direction. Tilted as possible. In addition, a stopper S that can be switched between a state in which the plate-like body A is prevented from sliding and a state in which the blocked state is released is provided at a lower portion of the placement surface D. Then, before the cut products A1 and A2 are cut out, the stopper S prevents the plate A from sliding on the placement surface D, and after the cut products A1 and A2 are cut out, the stopper The sliding-off prevention state of the plate-like body A due to S is released. Further, in the upper part below the inclined surface α, as shown in FIG. 1, the upper cut product A1 after the simultaneous cutting of the cut products A1 and A2 should be prevented from sliding down for a certain time during the sliding. A contact body 2 is provided that is freely contactable with the upper cut product A1. The contact body 2 is specifically configured as follows. That is, as shown in FIGS. 2 (a) and 2 (b), a pivot portion 15 is provided in the middle of the height of the support column 14 erected perpendicularly to the inclined surface α, and a swing rod 16 is provided on the pivot portion 15. Is mounted in a swingable manner by the driving force of the pneumatic cylinder 18, and a brush 17 that can contact the upper cut product A1 in a posture along the support column 14 is provided at the tip of the swinging rod 16. It is constituted by. The driving of the contact body 2 is executed in accordance with the timing of the relative movement of the second cutting blade B2.

  The inclination angle α is set in a range of 25 ° to 50 °. The inclination angle α is set in the range of 25 ° to 50 ° for the following reasons. That is, under the condition that the inclination angle α is larger than 50 °, the guide part (that is, a guide column 11 to be described later and the guide column 11 guides the relative movement when the second cutting blade B2 is relatively moved). The wear of the guide portion (combined with the guided body 12 to be guided) becomes particularly large and becomes impractical, while the inclination of the mounting surface D described above is under the condition that the inclination angle α is smaller than 25 °. This is because the downward sliding of the plate-like body A based on the above does not occur smoothly. In the present embodiment, as shown in FIG. 1, the inclination angle α is set to 45 °, but it goes without saying that the inclination angle α is not limited to this angle.

  A discharge device 13 for sending the two cut products A1 and A2 generated by the cutting out to a subsequent process is installed obliquely below the cutting device. The receiving surfaces of the cut products A1 and A2 in the discharge device 13 are in a state suitable for receiving the cut products A1 and A2 (that is, slightly inclined in the direction opposite to the inclination angle α of the mounting surface D described above). In a state where the inclined angle β is taken). The inclination angle β is, for example, 10 ° as shown in FIG.

  Next, a more detailed structure of the cutting device will be described.

  As shown in FIG. 5, the first cutting blade B1 and the second cutting blade B2 in the cutting device include a fixed lower die 3 disposed on the lower side of the eccentric press (see FIG. 3) and the upper side of the eccentric press. Between the up-and-down upper mold 4 that slides up and down freely. As a mechanism for sliding the elevating upper die 4 to be movable up and down with respect to the fixed lower die 3, a known eccentric drive mechanism shown in FIGS. An eccentric drive mechanism using the movement of the eccentric shaft E2 provided on the rotating eccentric wheel E1 (or a member corresponding thereto) is employed. The eccentric ring E1 and the eccentric wheel E1 are reduced so that the eccentricity of the eccentric shaft E2 is smaller as the cut-out length of the plate-like body A in the sliding direction is shorter or as the plate-like body A is thinner. It is possible to perform setup adjustment of the eccentric E1 by exchanging attached parts. In this way, when the setup adjustment of the eccentric wheel E1 can be performed, the productivity of the line for cutting the plate-like body A is set up by exchanging the eccentric wheel E1 and components attached thereto. Can be further improved. This is because the cycle time required for cutting the cut products A1 and A2 and for carrying in and out before and after the cut is the time during which the cut products A1 and A2 are being cut (that is, the cut products A1 and A2 are cut). It is determined by the sum of the waiting time when the blades B1 and B2 are engaged and the natural sliding is not yet started) and the time required for the natural sliding of the cut products A1 and A2 is started. However, when the cutting length in the sliding direction of the plate-like body A is long, the time required for the natural sliding is increased according to the length of the cutting length, and thus the cycle time is increased. While waste occurs, as described above, the setup adjustment of the eccentric wheel E1 is performed so that the eccentricity of the eccentric shaft E2 increases as the cutout length of the plate-like body A in the sliding-down direction increases. If so, the waiting time during which the cut products A1 and A2 are locked by the cutting blades B1 and B2 and the natural sliding does not start is shortened by the setup adjustment. This is because the cycle time can be shortened based on the shortening, and the waste of the cycle time can be reduced. In addition, as shown in FIG. 3, the state in which the up-and-down upper mold 4 slides up and down with respect to the fixed lower mold 3 is such that a guide column 11 standing on the fixed lower mold 3 side and its guide column A ring-shaped body that is externally fitted so as to be slidable on the guide 11 is guided smoothly based on a guide portion that is a combination with a guided body 12 that is attached to the lifting and lowering mold 4 side.

  As shown in FIG. 5, the fixed lower die 3 is elastically supported by a holder 5A of a lower blade 5 as a first cutting blade B1 and a spring 6 so that the lowering stroke of the upper and lower upper die 4 is the plate shape. A plate-like body end receiving portion 7 that is absorbable while carrying the end portion of the body A is attached. In addition, the edge part of the said plate-shaped body A becomes the chip A4 after the said plate-shaped body A is sheared. On the other hand, the upper and lower mold 4 is elastically held from above by the holder 8A of the upper blade 8 serving as the second cutting blade B2 and the spring 9 being pushed upward by the spring 9. A flexible plate-like body holding unit 10 is attached. The lower blade 5 is held by a holder 5A attached to the fixed lower die 3, while the upper blade 8 is held by a holder 8A attached to the elevating upper die 4. Thus, the first cutting blade B1, that is, the lower blade 5, and the second cutting blade B2, that is, the upper blade 8, can be relatively moved in the shearing direction. Moreover, as shown in FIGS. 6 and 7, the lower blade 5 and the upper blade 8 are designed in a shape that allows two sheets to be taken. 6 and 7 indicate the feeding direction of the plate-like body A.

  When carrying out the method of the present invention using the device of the present invention having the above-described configuration, the mounting surface D is previously inclined at an inclination angle α, and the plate is placed on the inclined mounting surface D. Since the plate-like body A is placed, the plate-like body A is placed on the mounting surface before the simultaneous cutting of the cut products A1 and A2 without using the supply means used in the conventional method. The plate-like body A is slid down naturally in conjunction with the relative movement of the second cutting blade B2 simply by being positioned above D, and the natural slid down causes the timing on the placement surface D. Can move well. In other words, the plate-like body A can be slid down naturally and moved to the above-described placement surface D in a timely manner without driving the supply means with appropriate timing as in the prior art. . The plate-like body A that has moved onto the placement surface D is cut off on the placement surface D by the function of the stopper S so that the sliding is prevented at a predetermined position on the placement surface D. Will be placed in position. Furthermore, after the plate-like body A is disposed at the cutting position, the relative movement of the second cutting blade B2 is performed, and after the two cut products A1 and A2 are cut out simultaneously, By releasing the slip-off prevention state by the stopper S, the lower cut product A2 of the two cut products A1 and A2 is naturally slid downward and sent out from above the placement surface D. be able to. In other words, the lower cut product A2 can be naturally slid down and sent out from above the placement surface D without driving the carry-out means at an appropriate timing as in the prior art. In the process of sending out the lower cut product A2, the upper cut product A1 of the two cut products A1 and A2 is brought into contact with the upper cut product A1 by the contact of the contact body 2. As shown in FIG. 2 (b), the two pieces of cut A1 and A2 are simultaneously slid down and interlaced based on the prevention. The situation in which the products A1 and A2 are not smoothly fed out is avoided, so that the new problem that the two cut products A1 and A2 are not smoothly fed out does not occur. The delivery of the upper cut product A1 is smoothly performed by releasing the contact of the contact body 2 with respect to the upper cut product A1 after the lapse of the predetermined time.

  Next, another embodiment will be described.

  In the above-described embodiment, the two cut products A1 and A2 are tile materials. However, the two cut products A1 and A2 are not limited to tile materials, and two tile products are taken. The present invention can be applied to other cut products.

  Further, even when the number of products to be cut simultaneously is three or more, the technical idea of the present invention is established in which the sliding of the upper cut product is delayed and the crossing of the upper and lower cut products is prevented. In this case, the sliding is delayed as the upper cut product.
