Description

  According to the present invention, a standard product having a square or rectangular planar shape is transferred in a column by a supply conveyor, while the fixed product is carried out in a plurality of rows to a discharge conveyor arranged at right angles to the side of the supply conveyor. With regard to the carrying device described above, even if the size of the standard product is changed, it is carried out while keeping the interval between the standard products constant.

  If the standard product transferred by the supply conveyor is a container, the unloading conveyor that unloads the container from the supply conveyor in units of a plurality of units includes, for example, a filling machine for the package to each container, or Vacuum packaging machines and the like are arranged at equal intervals. Therefore, even if the size of the fixed container changes, there is a condition that each container must always be carried out along the center line of the filling machine or the vacuum packaging machine.

  On the other hand, in Patent Document 1 below, rectangular containers are conveyed in a tandem shape by a supply conveyor, and the containers are positioned at equal intervals by a frame-shaped stopper, and three units of containers are laterally integrated. An apparatus for carrying out in a direction is disclosed. However, in the case of such a device, every time the size of the container is changed, it is necessary to change the size of the frame-type stopper, and there is a defect that it is not versatile.

  Patent Document 2 below discloses a device for receiving sausages carried by a plurality of rows of belts with stoppers and stopping them at equal intervals in the vertical direction, and carrying out the sausages in a plurality of rows in the horizontal direction. . In the case of such a device, the tip position of the sausage is determined by a stopper, and the tip position of each sausage is constant even if the length of each sausage is changed. However, the intermediate position of each sausage in the length direction has changed, and there is a problem that it does not coincide with the center line of the filling machine or the vacuum packaging machine.

  Therefore, the present invention can always carry out each of the shaped products whose sizes are changed on the supply conveyor by a simple operation in accordance with the change of the size of the shaped products along a plurality of delivery tracks defined in the delivery conveyor. It is what I did.

  In order to achieve the above object, the present invention provides a supply conveyor comprising a plurality of parallel string belts, a carriage supported on a guide rail parallel to the conveying direction of the supply conveyor, a carriage fixed to the carriage and the supply A stopper that prevents the transfer of the shaped product at the end of the conveyor, and first and second support bases formed by arranging two or more sets of plate members in front of and behind the gaps of the string belts of the supply conveyor; Means for supporting the first and second support bases on the carriage via first and second lifts on the front side of the stopper, respectively, and a side surface of the supply conveyor in the arrangement region of the both support bases. The cutting-edge shaped product, which is composed of a carry-out conveyor installed in a perpendicular direction from the top and is stopped by contacting the stopper, is pushed up by the first support base that receives the power of the first lift. The surface of the first support base that has been pushed up is used as a stopper to prevent the transfer of subsequent shaped products, while the subsequent shaped product is pushed up by the second support base that receives the power of the second lift, and each shaped product is supplied to the conveyor. And a means for sending out the front and rear fixed products in a side-by-side state along a plurality of unloading lines at the unloading conveyor by the unloading mechanism.

  When the standard product is used with a large or small size change, a plurality of unloading intervals on the carry-out conveyor and the center of each fixed product that is pushed out toward the carry-out line by the change in width. However, by moving the carriage along the guide rail and making the center of the cutting edge shaped product stopped by the stopper coincide with one carry-out line, it collides with the surface of the first support base. The center of the subsequent fixed product that stops at this point will inevitably coincide with the lead-out line of the baby.

  In FIG. 2 showing the plane, the pair of pulleys 12 and 13 supported by the frame 11 constitutes the supply conveyor 10 by stretching nine string belts 14 in parallel. A pair of guide rails 15 fixed to the inner surface of the frame 11 and arranged on both sides of the cord belt support the carriage 16 via four wheels 17. Also, as shown in FIG. 3, eight plate members are arranged in the front and back in the gaps between the nine strap belts 14 to form a first support base 20 and a second support base 21. Within the base cut 22, the support rods 18 of the nine strap belts 14 are installed between both walls of the carriage 16.

  In FIG. 3, the first support base 20 is connected to the carriage 16 via a first lift 25 formed by a fluid cylinder, and the second support base 21 is connected to the carriage 16 via a second lift 26 also formed by a fluid cylinder. On the other hand, an operating shaft 29 having a male screw 28 engaged with a female screw portion of the carriage 16 is rotatably arranged on the machine body 27 to constitute a control means 31.

  The supply conveyor 10 that is rotated by the power of the motor 19 (see FIG. 2) carries a fixed container 30 as an example of a standard product and transports the containers in a tandem shape. A stopper 23 fixed to the carriage 16 is arranged. For this reason, the most advanced container 30 conveyed as shown in FIG. 1 comes into contact with the stopper 23 at the end of the supply conveyor 10 and stops.

  When the sensor 33 that moves integrally with the stopper 23 detects the contact of the state-of-the-art container 30 with the stopper 23, the first support base 20 is moved up by the driving of the first lift 25 in FIG. The container 30 </ b> A is levitated from the supply conveyor 10, and the progress of the subsequent container 30 </ b> B is prevented by the rear wall surface of the first support base 20. Immediately thereafter, the subsequent container 30B is floated on the supply conveyor 10 together with the second support base 21 by the action of the timer.

  The side surface of the supply conveyor 10 in FIG. 2 has a carry-out conveyor 40 comprising two carry-out lines 41, 42 in a direction perpendicular to the transfer direction by the supply conveyor 10, and the opposite side surface has a first, The plurality of containers on the second support bases 20 and 21 are respectively provided with means 44 for pushing out and feeding the containers side by side toward the carry-out conveyor 40, and the plurality of containers 30A and 30B are respectively provided with the first carry-out. For example, the wire 41 and the second carry-out wire 42 can be sent out along the center of a vacuum packaging machine, for example.

  The plurality of containers 30C and 30D whose sizes are changed as shown in FIG. 4 are considerably smaller than those shown in FIG. 3, and the walls of the stopper 23 and the first support base 20 are the small containers. When the movements of 30C and 30D are blocked, the centers of the downsized containers 30C and 30D and the first carry-out line 41 and the second carry-out line 42 in FIG. As an example of solving the problem, the center of the containers 30C and 30D to be carried out is fixed to the fixed first carry-out line 41 by rotating the operating shaft 29 by the error of the container 30C used with respect to the basic numerical value with the handle 45. This matches the second carry-out line 42.

  As supplemented in FIG. 5, the leading container 30 </ b> A that is conveyed by the supply conveyor 10 and stops when the stopper 23 is blocked, and the subsequent container 30 </ b> B that stops when blocked by the wall surface of the first support base 20, have a fixed interval 47. Although it is sent out along the 1 carry-out line 41 and the 2nd carry-out line 42, when a container is reduced in size as shown by the virtual line 49, the stopper 23 is displaced by the value X amount integrally with the carriage, so that the first The support base 20 is also displaced by the amount corresponding to the value X, and the center of the miniaturized container can be made to coincide with the first carry-out line 41 and the second carry-out line 42 of the fixed interval 47.

  FIG. 6 is an explanatory view of guide bars arranged on both sides of the first unloading line 41 and the second unloading line 42 described above, and two drives arranged along the upper surface of the surface plate 50. The side guide bars 51 and 52 and the two driven side guide bars 53 and 54 are provided. The operation screw rod 55 arranged along the lower side of the surface plate 50 forms a right screw 56 and a left screw 57, and engages the female screw of the drive side guide bar 51 on one side with the right screw 56. On the other hand, the female screw of the driving side guide bar 52 on the other side is engaged with the left screw 57.

  Also, the two rows of long holes 60 formed in the surface plate 50 are elements that enable the movement of the one drive side guide bar 51 located in that portion, and are larger than the thickness of the surface plate 50 as shown in FIG. A washer 61 having a larger thickness is disposed in the long hole 60, and a bracket 62 fixed to the guide bar 51 with a screw 64 via the washer 61 is provided with a female screw 63, and the female screw 63 engages the operation screw shaft 55. To do. Therefore, the drive-side guide bars 51 and 52 can be moved within the length of the long hole 60 by the rotation of the operation screw rod 55.

  In addition, the distal ends of a pair of band-shaped connecting members 65 extending from a part of the bracket 62 connect the driven side guide bars 53 and 54 at a portion of a separate long hole 63. When both the drive side guide bars 51 and 52 are relatively approached by the rotation of the screw rod 55, the drive side guide bar 51 and the driven side guide bar 54 on the one side, the drive side guide bar 52 and the driven side guide on the other side. The bar 53 moves in synchronization. For this reason, the drive-side guide bar 51 and the driven-side guide bar 53 are relatively close to each other on both sides of the first carry-out line 41, and the other-side drive-side guide bar 52 and the driven-side guide bar 54 are connected to the second carry-out line. The two 42 are relatively close to each other and serve to guide a plurality of side-by-side containers mounted on the carry-out conveyor.

  In FIG. 2, the screw rod 29 manually rotated by the handle 45 can be controlled by the rotational power of the pitching motor 70. For example, as shown in FIG. 5, when the size of the standard product is input from the input device 68 to the controller 69, the calculation unit in the controller sends a command signal corresponding to the size of the container 30A to be used to the pitching motor 70 and screw. It is possible to control the momentum of the stopper 23 and the first support base 20 by rotating the shaft 29 by the momentum of the pitching motor 70. As another example, the movement of the stopper 23 and the like can be controlled by the fluid cylinder 75 servo-controlled by the controller 69.

  In FIG. 3, two lifts 25 and 26 are formed by fluid cylinders, and a time difference is provided in the movement of the first support base 20 and the second support base 21 by the time difference movement of both lifts. 1, the two front circumferential cams 77 and 78 fixed to the shaft 76 form a delay in the action of the two lifts 25 and 26 via the two lifting rods 78 and 79, so that the first support base A time difference is provided in the movement of the 20 and the second support base 21.
