The tip edge detection sensors 37A and 37B are optical sensors, and are provided corresponding to left and right edge clamps 51L and 51R described later. When both the leading edge detection sensors 37A and 37B simultaneously detect the leading edge (downstream edge) of the fabric member 5, the leading edge can be detected as being in a state orthogonal to the transport direction. When the detection of the other sensor is delayed with respect to the detection of one of the leading edge detection sensors 37A and 37B, both sides of the leading edge of the fabric member 5 are inclined in the transport direction (front-rear direction). (See FIG. 4).

  The dough member pulling means 9 is configured to pull out (pull out) the dough member 5 conveyed in the downstream direction by the conveying means 7 onto the transfer means 13 and fold it in half, and is configured as follows. It is. That is, the fabric member pulling means 9 is provided with a longitudinally moving member 39 that is movable in the longitudinal direction (Y-axis direction). The longitudinally moving member 39 is configured to be moved in the longitudinal direction by driving of the longitudinally moving drive means 41 provided in the beam member 31. The forward / backward drive means 41 comprises, for example, a ball screw mechanism. A nut member (not shown) screwed to a ball screw (not shown) rotated by the servomotor 43 is provided, and the forward / backward movement member 39 is integrally connected to the nut member.

  Therefore, by rotating the servo motor 43 forward and backward, the longitudinally moving member 39 is reciprocated in the longitudinal direction. For example, the longitudinal movement position of the longitudinally moving member 39 with respect to the reference position such as the last retracted position or the most advanced position is detected by a position detection device (not shown) such as a rotary encoder provided in the servomotor 43. It is. In addition, although the case of the ball screw mechanism was illustrated as the back-and-forth motion drive means 41 for moving the back-and-forth motion member 39 back and forth, examples of the back-and-forth motion drive means 41 include a fluid pressure cylinder that can freely move back and forth, a linear motor, Various configurations such as a configuration using an endless chain rotated by a servo motor can be employed. Further, as the position detection device, for example, a linear scale such as a magnescale can be adopted.

  A support bracket 47 is provided at the lower end portion of a pair of support rods 45 that are integrally suspended from the longitudinally moving member 39, and the support bracket 47 is positioned in the left-right direction (at the front side of the support rod 45 ( A support shaft 49 that is long in the X-axis direction is supported horizontally and rotatably. The left and right edges of the support shaft 49 can be gripped on both the left and right sides of the downstream edge (tip edge) of the rectangular fabric member 5 conveyed in the downstream direction by the conveying means 7. Clamps 51L and 51R are provided. The end edge clamps 51L and 51R include upper and lower clamp jaws 53U and 53L that can freely clamp the front end edge (downstream end edge) of the dough member 5 from above and below, respectively. Shaped sub-clamp jaws 55U and 55L are integrally attached. Of the upper and lower clamp jaws 53U and 53L, the lower clamp jaw 53L opens and closes up and down by the operation of an opening and closing actuator (not shown) such as a small fluid pressure cylinder.

  The left and right edge clamps 51L and 51R grip the downstream edge of the dough member 5 that is conveyed and conveyed in the downstream direction from the conveyor belts 15A to 15D in the conveying means 7, and the downstream end of the dough member 5 described above. When gripping the edge, the clamp jaws 53U, 53L are in a standby state in which the clamp jaws 53U, 53L are opened up and down toward the transport means 7. That is, as shown in FIG. 5, the left and right edge clamps 51 </ b> L and 51 </ b> R are closest to the front end portion of the conveying means 7 at the position where the longitudinally moving member 39 is finally retracted. The upper and lower clamp jaws 53U and 53L are in a standby state in which the upper and lower clamp jaws 53U and 53L are opened in the vertical direction toward the conveying means 7.

  When the downstream edge of the fabric member 5 is carried between the upper and lower clamp jaws 53U and 53L in the edge clamps 51L and 51R and the downstream edge of the fabric member 5 is gripped by the clamp jaws 53U and 53L, the front and rear The moving member 39 is moved in the forward direction (leftward in FIGS. 5 and 6). As described above, the longitudinal movement member 39 is moved in the forward direction, and the edge clamps 51L and 51R are moved in the forward direction, whereby the dough member 5 is pulled in the downstream direction onto the transfer means 13. As shown by an imaginary line in FIG. 5, when transferring, swing guide means 57 for guiding the upper and lower clamp jaws 53U, 53L in the edge clamps 51L, 51R gradually downward is directed. Is provided.

  More specifically, as shown in FIGS. 5 and 6, the end edge clamp 51 </ b> R is provided with a swing guide member 59 protruding forward, and a guide roller is provided at the front end side of the swing guide member 59. 61 is rotatably provided. The beam member 31 is provided with a rotation guide member 63 for guiding the guide roller 61 and rotating the edge clamps 51L and 51R up and down. More specifically, the rotation guide member 63 is attached to the beam member 31 in the vicinity of the position where the longitudinally moving member 39 is most advanced. The lower part of the rotation guide member 63 is provided with an inclined portion 63A slightly inclined in the rear direction, that is, in a direction close to the conveying means 7, and the lower end portion of the inclined portion 63A is higher than the support bracket 47. The position is provided with a horizontal portion 63B in the rearward direction.

  The rotation guide member 63 has a structure in which the guide roller 61 is sandwiched and guided. However, the rotation guide member 63 is formed in a guide rail shape, and the guide rail is configured as a plurality of guide rollers 61. It is also possible to adopt a configuration sandwiched between. That is, the swing guide member 59 can be provided with a roller bracket so as to be rotatable, and a plurality of guide rollers 61 guided by sandwiching the guide rail can be provided on the roller bracket. It is.

  In the above configuration, when the leading edge (downstream edge) of the fabric member 5 is clamped by the clamping jaws 53U, 53L in the edge clamps 51L, 51R, the longitudinally moving member 39 is moved forward (from the last retracted position). 5 and 6, the guide roller 61 provided in the swing guide member 59 attached to the edge clamp 51 </ b> R is guided by the rotation guide member 63 and moved forward. When the guide roller 61 is moved along the rotation guide member 63, the guide roller 61 gradually rises along the rotation guide member 63, so that the edge clamps 51 </ b> L and 51 </ b> R are interposed via the swing guide member 59. Then, it is gradually rotated downward around the support shaft 49.

  That is, the upper and lower clamp jaws 53U, 53L provided in the edge clamps 51L, 51R are gradually rotated so as to be directed downward. When the forward / backward moving member 39 moves to the vicinity of the position where the rotation guide member 63 is attached to the beam member 31, the support bracket 47 that supports the edge clamps 51 </ b> L and 51 </ b> R is guided by the rotation guide member 63. The guide roller 61 is moved in the forward direction. Therefore, as shown by phantom lines in FIGS. 5 and 6, the swing guide member 59 is inclined so that the upper end portion is located on the rear side (right side in FIGS. 5 and 6) from the lower end portion.

  As described above, when the longitudinally moving member 39 is moved in the forward direction from the last retracted position, the dough member 5 clamped (gripped) by the clamp jaws 53U and 53L in the edge clamps 51L and 51R is removed from the conveying means 7. It is pulled out (pulled out) and transferred onto the transfer means 13. Then, by returning the longitudinally moving member 39 to the original position, the edge clamps 51L and 51R are also returned to the original position. Therefore, as shown by an imaginary line in FIG. 6, the leading edge of the dough member 5 held by the clamp jaws 53U and 53L is folded back, and the dough member 5 is folded in half on the transfer means 13. It will be.

  The transfer means 13 is composed of a general belt conveyor, and functions to transfer the dough member 5 folded in two in the direction of the packaging device 11. This transport means 13 transports the dough member 5 in a direction perpendicular to the transport direction of the transport means 7, that is, in a direction parallel to the folding line of the dough member 5 folded in half. 11, the dough member 5 folded in half is fed. The transfer means 13 is disposed at a position lower than the conveyor belts 15A to 15D in the transfer means 7 and lower than the edge clamps 51L and 51R. Between the means 13, an inclined path 65 that is inclined so that the transfer means 13 side is lowered is provided. In the vicinity of the lower end of the inclined path 65, a passage detection sensor 67 for detecting passage of the leading edge (downstream edge) 5A and the trailing edge (upstream edge) 5B of the fabric member 5 is provided. .

  The passage detection sensor 67 is an optical sensor, and detects the passage of the rear end edge 5B of the fabric member 5 and stops the forward and backward movement member 39 from moving forward after a predetermined time has elapsed. It functions. The passage detection sensor 67 detects that the leading edge 5A of the fabric member 5 has passed when the light receiving state changes from the light receiving state to the light shielding state. It is detected that the edge 5B has passed.

  Note that the packaging device 11 is a device in which the dough member 5 carried in from the transfer means 13 is wound into a round bar shape and the dough member 5 is wrapped with a resin film. This type of packaging device is already well known. Therefore, the detailed description of the configuration of the packaging device 11 is omitted.

  In the configuration as described above, the rectangular dough member 5 is expanded and the leading edge (downstream end edge) 5A of the dough member 5 is orthogonal to the conveying direction (front-rear direction, Y-axis direction) of the conveying means 7. When positioned in the direction (left-right direction, X-axis direction) and placed on the conveying means 7, the dough member 5 is conveyed in the forward direction (downstream direction). When the leading edge 5A of the fabric member 5 is detected by the leading edge detection sensors 37A and 37B, the clamp jaws 53U and 53L provided in the left and right edge clamps 51L and 51R previously positioned at the last retracted position, The leading edge 5A of the fabric member 5 is gripped by the Peugeots 55U and 55L.

  At this time, as shown in FIG. 4, when the leading edge 5A of the dough member 5 is inclined in the front-rear direction with respect to the direction orthogonal to the transport direction, first, one leading edge detection sensor 37A is first moved to the leading edge 5A. Is detected. When one leading edge detection sensor 37A detects the leading edge 5A, one edge clamp 51R corresponding to the leading edge detection sensor 37A clamps the leading edge 5A. Note that the edge clamp 51R performs a clamping operation (clamp jaw) after a preset time (time when the leading edge 5A of the fabric member 5 reaches the edge clamp 51R) after the leading edge detection sensor 37A detects and operates. 53U, 53L closing operation). When the other leading edge detection sensor 37B detects the leading edge 5A, the other edge clamp 51L corresponding to the leading edge detection sensor 37B performs a clamping operation.

  Therefore, when the dough member 5 is placed on the conveying means 7, the tip edge 5A of the dough member 5 is not in a state orthogonal to the carrying direction but is slightly inclined in the front-rear direction. Even when the leading edge 5A of the fabric member 5 is gripped by the left and right edge clamps 51L and 51R in the fabric member pulling means 9, the leading edge 5A of the fabric member 5 is orthogonal to the conveying direction of the conveying means 7. The position is corrected in the direction.

  As described above, when the front edge 5A of the fabric member 5 is clamped by the left and right edge clamps 51L and 51R, the front-rear drive means 41 is operated, and the front-rear moving member 39 moves forward from the last retracted position. Therefore, the dough member 5 is pulled forward from the conveying means 7 by the edge clamps 51L and 51R. At this time, the rear end edge 5B side of the fabric member 5 is dragged on the slope 65, and the passage detection sensor 67 detects the passage of the rear end edge 5B of the fabric member 5. After the passage detection sensor 67 detects the passage of the trailing edge 5B of the dough member 5, a predetermined time set in advance, that is, after a lapse of time for the trailing edge 5B to move onto the transfer means 13, the longitudinally moving member 39 is provided. The forward movement of is stopped.

  As described above, the movement position in the Y-axis direction when the longitudinally moving member 39 moves in the forward direction (Y-axis direction) from the last retracted position is detected by position detection means such as a rotary encoder provided in the servo motor 43. ing. Further, the position in the front-rear direction of the passage detection sensor 67 and the approximate position of the rear end edge 5B of the dough member 5 positioned on the transfer means 13 through the passage detection sensor 67 are known.

  Therefore, after detecting that the longitudinally moving member 39 has advanced to the most advanced position by the position detecting means, or after the rear end edge 5B of the dough member 5 is placed on the transferring means 13, the longitudinally moving member By returning 39 to the original position, the dough member 5 is placed on the transfer means 13 in a folded state. At this time, the position detecting device detects that the longitudinally moving member 39 has returned to the position corresponding to the rear end edge 5B of the dough member 5, and releases the clamp of the front end edge 5A by the end edge clamps 51L and 51R. Thus, the rear end edge 5B and the front end edge 5A of the fabric member 5 can be folded in a double fold. And when the said longitudinally moving member 39 returns to the original last retracted position, it will return to an initial state.

  As described above, when the dough member 5 is placed in a folded state on the transfer means 13, the transfer means 13 starts to transfer the dough member 5 to the packaging device 11.

  As can be understood from the above description, the edge member 51A, 51R that has moved forward by clamping the front edge 5A of the fabric member 5 is moved back to the original position, and the fabric member 5 is moved to the second position. Since it is folded in a fold, the edge clamps 51L and 51R can be folded in half with a simple configuration in which the edge clamps 51L and 51R reciprocate in the front-rear direction.

  The present invention is not limited to the embodiment as described above, and can be implemented in other forms by making appropriate changes. That is, in the above description, the guide rollers 61 provided on the swing guide member 59 attached to the edge clamp 51R are guided by the rotation guide member 63, whereby the edge clamps 51L and 51R are rotated around the support shaft 49. The configuration for rotating (swinging) is described. However, for example, a motor or a fluid pressure cylinder may be operated corresponding to the longitudinal movement position of the longitudinal movement member 39 to rotate the edge clamps 51L and 51R via the support shaft 49. is there.
