JP-A-2005-111614

  In the conventional joint cutting device, since a slit is formed in the side wall that divides the storage chamber and the transfer chamber, the cutting powder of the joint generated in the transfer chamber enters the storage chamber through the slit. There is a problem in that it may adhere to a transmission body in the accommodation chamber, and it takes time for maintenance such as cleaning.

  The problem to be solved by the present invention is that, instead of using a transmission body such as a belt or a chain and a transmission body drive motor that drives the transmission body, an actuator that has never been used in a joint cutting device is used. An object of the present invention is to provide a nodular cutting device that is easier to maintain such as cleaning than the like cutting device.

  The knot cutting device of the present invention is a device that cuts knots with a rotary blade to produce a knot, and includes a main body having a cutting chamber and a motor chamber partitioned by a partition body having no opening such as a slit. ing. The cutting chamber of the main body accommodates a rotary blade for cutting joints, a joint holder for holding joints, and a slide mechanism for sliding the joint holders in the front-rear direction. The motor chamber houses a rotary blade motor that rotates the rotary blade. The rotary blade is arranged in front of the movement direction of the joint holder, and when the joint holder moves forward by the slide mechanism, the joint held by the joint holder is cut by the rotary blade. ing.

  In the nodular cutting device of the present invention, the cutting chamber and the motor chamber are partitioned by a partition having no opening, so that the cutting powder does not easily enter the motor chamber, and the cutting dust adheres to the rotary blade motor in the motor chamber. Hard to do. Further, since the belt or chain used in the conventional knot cutting device is not used, it does not adhere to the belt or chain, and maintenance such as cleaning is easy.

In FIG. 1, 1 is a main body, 2 is a linear base, 3 is a slider, 4 is an attachment, 5 is a joint holder, 6 is a moving path, 7 is a rotary blade, 8 is a transmission mechanism, 9 is a collection case, An introduction hood, M is a motor for a rotary knife, C is a controller, and F is a joint (a bonito). The knot holder 5, the moving path 6, the rotary knife 7, the transmission mechanism 8, the introduction hood 10, and the rotary knife motor M are provided one by one on both outer sides in the width direction of the linear base 2. In the following, front and rear are represented with reference to the movement direction of the node F, and the front of the movement direction during cutting is the front and the rear is the rear.

  As an example, the main body 1 shown in FIG. 1 includes an upper cutting chamber 1a and a lower motor chamber 1b. The cutting chamber 1a and the motor chamber 1b are partitioned by a partition body (bottom plate of the cutting chamber 1a) 1c that does not include openings such as slits and holes. A wiring chamber 1d is provided below the motor chamber 1b. The cutting chamber 1a has an upper surface opening, and the main body 1 is provided with a lid 11 for opening and closing the upper surface opening so as to be rotatable. The lid 11 is provided with a handle 11a used for opening and closing.

  The joint cutting device of the present invention is configured not to operate when the lid 11 is open. In this embodiment, a lid detection sensor 12 for detecting that the lid 11 is closed is provided on the peripheral wall on the upper end side of the cutting chamber 1a, and a corner portion of the lid 11 (the lid detection sensor 12 when the lid 11 is closed) is provided. A cover portion 11b is provided on a portion of the cover 11b. On the contrary, you may make it provide the cover part 11b in the cutting chamber 1a side, and the cover detection sensor 12 in the cover 11 side. In this embodiment, a transparent window 11c such as a glass plate or an acrylic plate is provided in a part of the lid 11 so that the inside of the cutting chamber 1a can be seen from the outside. If necessary, the main body 1 can be provided with an adjuster 1e for height adjustment as shown in FIG. The main body 1 described here is an example, and a structure other than this can be adopted.

  The linear base 2 is a rail member for the slider 3 to move. As the linear base 2 and the slider 3, a commercially available actuator (for example, IS series actuator of IAI Corporation) can be used. In this embodiment, the slider 3 is moved by air supplied from a compressor (not shown). The linear base 2 and the slider 3 here are the slide mechanisms described in the claims.

  The slider 3 is provided with a detected body 3a (FIGS. 3A and 3B). The detected body 3a passes through the upper surface of the partition body 1c and above the detection portion of the detection sensor 21 (FIG. 3A) provided between the linear base 2 and the moving passage 6. . When the detected object 3a reaches above the detection sensor 21 with the forward movement of the slider 3, the forward movement of the slider 3 is stopped and switched to the backward movement. The detected body 3 a can also be provided on the attachment 4 or the node holder 5. In any case, the detected body 3a is provided at a position covering the upper side of the detection unit of the detection sensor 21. In the present invention, by providing the detection sensor 21, overcutting of the joint F and contact of the joint holder 5 with the rotary blade 7 can be reliably prevented. The slider 3 is set so that the speed of backward movement (hereinafter referred to as “return speed”) is faster than the forward movement during cutting, so that no time loss occurs.

  The linear base 2 and the slider 3 described here are examples, and a structure other than this may be employed. Although not shown, an air jetting means (not shown) is connected to the linear base 2, and the air blown out from the air jetting means causes the cutting powder in the cutting chamber 1a to be moved from the linear base 2 to the slider 3. It can be prevented from adhering to the surface.

  An attachment 4 is attached to the upper surface of the slider 3. The attachment 4 is a member for fixing the joint holder 5. As an example, the attachment 4 shown in FIG. 1 has a letter-like shape in plan view, and two attachment pieces 4a project downward from the bottom surface. One attachment holder 5 is attached to each attachment piece 4a. The attachment 4 and the joint holder 5 move in the same direction as the slider 3 moves in the front-rear direction. The attachment 4 described here is an example, and a structure other than this can be adopted.

  The joint holder 5 is a chuck member that holds the joint F to be cut. As an example, the joint holder 5 shown in FIGS. 3A and 3B and FIG. 4 is provided on the lower holding body 5a fixed to the attachment piece 4a of the attachment 4 and on the upper side of the lower holding body 5a. The upper clamping body 5b is provided. The lower clamping body 5a and the upper clamping body 5b are configured such that the distal end side approaches and separates. The tip side of the upper holding body 5b is in contact with the tip side of the lower holding body 5a when the node F is not held. The upper holding body 5b is provided with a handle bar 5c. By tilting the handle bar 5c rearward, the distal end side of the upper sandwiching body 5b is separated from the distal end side of the lower sandwiching body 5a (the leading end side of both of them). The interval is widened). The knot holder 5 may be directly fixed to the slider 3. In this case, the attachment 4 can be omitted. The knot holder 5 described here is an example, and a structure other than this can be employed.

  The moving passage 6 is a passage through which the node F held by the node holder 5 moves. The moving passage 6 is provided in one row (two rows in total) on both sides in the width direction of the linear base 2. The movement path 6 can be in a single row or in three or more rows. As an example, the moving path 6 shown in FIGS. 3 (a) and 3 (b) includes a recess of a bowl-shaped member having two side walls 6a and 6b and a ground surface 6c, specifically, the side walls 6a and 6b and the ground surface. It is provided in the part enclosed by 6c. The side wall (hereinafter referred to as “inside wall”) 6a of the bowl-shaped member is erected vertically or substantially perpendicular to the ground surface 6c, and the other side wall (hereinafter referred to as “outer wall”) 6b It is erected diagonally outward with respect to 6c. The inner wall 6a and the outer wall 6b are configured to be V-shaped when viewed from the rotary blade 7 side, with the lower side being narrow and the upper side being wide. In this way, since it is V-shaped, at least two points of the node F are supported, so that there is an advantage that the node F is more stable than when placed on a plane. The bowl-shaped member constituting the moving passage 6 is attached to the partition 1c so that the position of the bowl-shaped member can be adjusted by moving in the front-rear direction. The movement path 6 can also be comprised by members other than a bowl-shaped member. The movement path 6 can also be configured without using a member.

  A flat mounting body 6d (FIG. 3A) is provided outside the inner wall 6a (on the side of the linear base 2). The attachment body 6d is provided with an elongated slot (not shown) in the front-rear direction. A gap adjusting member 6e for adjusting the gap with the rotary blade 7 is attached to the attachment body 6d. The gap adjusting member 6e is attached to the attachment body 6d by a stopper (not shown) inserted into the elongated hole of the attachment body 6d, and the position in the front-rear direction is moved by moving back and forth within the range of the elongated hole. It can be adjusted. The gap between the gap adjusting member 6e and the rotary blade 7 is adjusted by the movement of the gap adjusting member 6e. Since the rotary blade 7 is a consumable item and is worn by use, it is necessary to adjust the gap appropriately. In addition, the gap needs to be adjusted when the rotary blade 7 is replaced with one having a larger diameter or smaller diameter than that in use.

  As shown in FIGS. 3A and 4, a pressing piece 13 is provided at a position closer to the front side of the outer wall 6 b to prevent the node F in contact with the rotary blade 7 from being lifted. In this embodiment, the nodes F are supported at three points by the side walls 6a and 6b and the pressing piece 13, and can be moved in a stable state. The pressing piece 13 is provided on a rotating shaft 14 that is rotatably fixed to the outer wall 6b. A biasing spring 16 is provided on the outer periphery of the rotating shaft 14. One end of the biasing spring 16 is assigned to the surface of the pressing piece 13 on the rotary blade 7 side. Thereby, the pressing piece 13 is urged toward the node holder 5 when the node F is not touching.

  An arm 15 protrudes from the outer periphery on the upper side of the rotating shaft 14. As an example, the arm 15 shown in FIGS. 1 to 5 includes a base piece 15a parallel to the rotation shaft 14 and a curved piece 15b erected perpendicularly to the base piece 15a. The curved piece 15b is formed by bending the outer end of the base piece 15a. In this embodiment, a speed switching sensor 17 (FIGS. 5A and 5B) is provided on the outer surface of the outer wall 6b, the arm 15 rotates with the rotation of the rotating shaft 14, and the curved piece 15b is a speed switching sensor. When it overlaps with 17 detection units, the moving speed of the slider 3 is switched (slowed).

  Specifically, the slider 3 has a moving speed (hereinafter referred to as “initial speed”) from the initial position (the position shown in FIG. 1 or 3A) until the bending piece 15b overlaps the detection portion of the speed switching sensor 17. ) Is fast, and from the time when the curved piece 15b overlaps the detection portion of the speed switching sensor 17 until the switching to the backward movement after the end of cutting, the speed is slower than the initial speed (hereinafter referred to as “cutting speed”). . By doing in this way, while the loss of the movement time until cutting is started can be eliminated, the overload to the rotary blade 7 at the time of cutting can be prevented.

  The rotary blade 7 cuts the node F. An existing tool (for example, the one shown in Patent Document 1) can be used as the rotary blade 7. The rotary blade 7 is rotatably mounted on the blade mounting shaft 18. The rotary knife 7 can be replaced. The rotary blade 7 is arranged on the front side of the moving passage 6 so that the node F that has moved forward in the moving passage 6 can be cut.

  The transmission mechanism 8 is a mechanism for transmitting power from the rotary blade motor M to the rotary blade 7. As an example, the transmission mechanism 8 shown in FIG. 1 includes a first pulley 8a attached to the output shaft S of the rotary blade motor M, a second pulley 8b attached to the blade attachment shaft 18, a first pulley 8a, and a second pulley. A transmission belt 8c is provided around the outer periphery of 8b. An existing timing belt or the like can be used for the first pulley 8a and the second pulley 8b, and an existing timing belt or the like can be used for the transmission belt 8c. A bearing 19 is provided in the middle stage of the blade mounting shaft 18 so that the blade mounting shaft 18 rotates smoothly. Two or more bearings 19 can be provided on each blade mounting shaft 18. If not required, the bearing 19 can be omitted. The front end side of the blade attachment shaft 18 penetrates the partition 1c and protrudes toward the cutting chamber 1a, and the rotary blade 7 is rotatably attached to the protruding portion. Although not shown, a height adjusting spacer is provided below the rotary blade 7.

  The recovery case 9 is a case for recovering the cut shaving node. As an example, what is shown in FIG. 1 is a cube having an upper surface opening (not shown). The interior of the housing case 9 is partitioned vertically by a single perforated plate 20. The upper space (hereinafter referred to as “upper recovery chamber”) 9a is a portion in which the cutting node is accommodated, and the lower space (hereinafter referred to as “lower recovery chamber”) 9b is a portion in which cutting pieces and shavings smaller than the set size are accumulated. is there. Although not shown, a drawer is provided in the lower collection chamber 9b so that cutting pieces and the like can be collected therein. The collection case 9 can be placed on a case placement portion (not shown) provided in the main body.

  In this embodiment, the collection case 9 is made of a transparent material (acrylic plate or glass plate) so that the state in which the shaving node is collected can be visually recognized from the outside. By doing in this way, it can utilize as an apparatus for performance in a store etc. The collection case 9 can be made of an opaque material.

  The introduction hood 10 is a member for introducing the cut shaving node into the collection case 9. As an example, the introduction hood 10 shown in FIG. 1 has a cylindrical shape in which an inlet is provided on one end side and an outlet is provided on the other end side. By arranging the inlet on the cutting chamber 1a side and the outlet on the upper surface opening side of the collecting case 9, a passage from the cutting chamber 1a to the collecting case 9 is established. The cutting node cut in the cutting chamber 1 a reaches the collection case 9 through the introduction hood 10. A portion of the upper surface opening of the collection case 9 where the introduction hood 10 is not provided is closed with an upper cover (not shown) so that the shaving node does not scatter outside the collection case 9.

  The controller C sets the rotational speed of the rotary blade 7, the moving speed of the slider 3 (initial speed, cutting speed, return speed) and the like. There is no difference between the two types of node F, and there are individual differences. For this reason, even if a certain section F can cut an appropriate size, another section F may not be able to cut an appropriate size. This is a problem caused by the difference in the amount of water and the hardness contained in the knot F.

  In the present invention, the controller C can set the rotational speed of the rotary blade 7 and the moving speed of the slider 3 to speeds suitable for the individual nodes F. The shaving node becomes thinner when the rotational speed (the number of revolutions per unit time) of the rotary blade 7 is increased, and becomes thicker when the rotational speed is decreased. Further, the shaving node becomes thicker when the cutting speed of the slider 3 is increased and becomes thinner when the cutting speed is decreased. In this embodiment, the rotational speed of the rotary blade 7 can be set in the range of 0 to 2800 rpm, and the cutting speed can be set in the range of 0.1 to 2.0 m / sec. The numerical value shown here is an example and does not exclude other numerical values.

  Although not shown, the controller C of this embodiment is provided with a display screen, a power button, an abnormality release button, a feed (forward / reverse) button, an operation button, and a stop button. A power button, an error release button, a feed (forward / reverse) button, an operation button, and a stop button are provided on the lower side of the display screen. Other designs of the controller C may be used.

  In addition, the structure shown in the said embodiment is an example to the last, and the joint cutting apparatus of this invention is not limited to the structure shown by the said embodiment. Moreover, as long as there exists an effect of the joint cutting apparatus of this invention, the structure of the said embodiment can be changed and abbreviate | omitted suitably.

  The knot cutting device of the present invention can be widely used for cutting various knots F such as a knot, a knot, and a knot.
