Description

  The present invention is an improvement of a bag transport apparatus, more specifically, even a bag that is easily deformed can be reliably transferred without being damaged, and the transfer amount per unit time can be increased. Thus, the present invention relates to a reversible wrapping unloader that can contribute to improvement in work efficiency and, in turn, cost reduction, and a wrapping bag conveyance method using the same.

  As is well known, recently, operations in a production line factory are automated, and a plurality of processing steps are automatically performed by a machine. However, in a food processing plant, for example, a retort pouch is easily deformed. Since the form is unstable for transferring the wrapped bag, it has been difficult to handle with a normal belt conveyor, and thus a device for lifting the wrapped bag by vacuum suction has been conventionally disclosed (for example, Patent Document 1). reference).

However, such a suction type device has a problem that it cannot be lifted well due to the state of intake air, or the bag is accidentally dropped and damaged.

It can be said that it is expensive.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

  In the figure, what is indicated by reference numeral 1 is a batch tray, and this batch tray 1 is a plate-like body on which a plurality of wrapping bags P can be placed in a planar state.

  Also, what is indicated by reference numeral 2 is a tray conveying conveyor means, and the tray conveying conveyor means 2 can place the batch tray 1 and convey it to a predetermined position (opposite surface of a roller conveyor 4 described later). In this embodiment, a known chain conveyor is used.

  Furthermore, what is indicated by reference numeral 3 is a tray clamp mechanism, and this tray clamp mechanism 3 can clamp the batch tray 1 from the front and rear and lift it upward by opposing latching claw members. .

  Further, what is indicated by reference numeral 4 is a roller conveyer means. The roller conveyer means 4 has a large number of feed rollers 41, 41... Arranged at predetermined parallel intervals, and each of these feed rollers 41 and A restraining bar 42 is arranged between 41 and so that it can appear and disappear.

  In the present embodiment, a sponge body, a soft rubber body, a urethane material, or the like can be used as the restraining bar 42, and the displacement and damage of the bag P can be prevented.

  Furthermore, what is indicated by reference numeral 5 is a base member, and at least one surface of the base member 5 is provided with the tray clamp mechanism 3 and the roller conveyor means 4.

  Furthermore, what is indicated by reference numeral 6 is a turning mechanism portion, and the turning mechanism portion 6 turns the base member 5 so as to sandwich the bag P between the batch tray 1 and the roller conveyor means. 4 can be inverted up and down and the batch tray 1 can be moved upward. In this embodiment, a known servo motor is employed.

  Further, what is indicated by reference numeral 7 is a drive motor. This drive motor 7 drives the feed rollers 41, 41,... Of the roller conveyor means 4 all at once, and wraps P, P,. Is carried out in a predetermined direction.

  An embodiment of a bag transport method using a reversible bag unloader according to the present invention will be described below with reference to FIGS. First, a batch tray 1 on which a plurality of wrapping bags P are placed in an aligned state is placed on a tray transporting conveyor means 2 (see FIG. 1), and a predetermined position (a downward roller conveyor 4 on a base member 5). (Refer to FIG. 2).

  In this way, the batch tray 1 placed on the tray conveying conveyor means 2 on which the wrapping bags P, P,... Are placed is clamped from the front and rear by the tray clamp mechanism 3 and lifted upward (see FIG. 3).

  Next, a large number of feed rollers 41, 41,... Are arranged on the roller conveyor means 4 at predetermined parallel intervals, and a restraining bar 42 is arranged between the feed rollers 41 and 41 so as to be able to appear and retract. On the other hand, by projecting these holding bars 42, the packaging bags P, P,... Lifted together with the batch tray 1 by the tray clamp mechanism 3 are sandwiched between the trays (see FIG. 4).

  At this time, the tray clamp mechanism 3 is expanded and contracted to lift the batch tray 1 from the tray transporting conveyor means 2 and, in addition, the base member 5 can be biased in the direction of the roller conveyor means 4, The bag P can be securely held.

  At this time, by retracting the tray conveying conveyor means 2 that has conveyed the batch tray 1 to the side of the roller conveyor means 4, it is possible to prevent interference during the operation of the roller conveyor means 4.

  Further, in this embodiment, the wrapping mechanism portion 6 stops the disposition surface of the roller conveyor means 4 in the base member 5 substantially horizontally, so that the wrapping bag P is not displaced and can be stably placed. .

  After that, the base member 5 provided with the tray clamp mechanism 3 and the roller conveyor means 4 on at least one surface is turned by the turning mechanism 6 and the packaging bag P is sandwiched between the batch tray 1. The roller conveyor means 4 is turned upside down and the batch tray 1 is moved upward (see FIGS. 5 and 6).

  Then, the batch tray 1 is separated by the tray clamp mechanism section 3, and the feed rollers 41, 41,... Of the roller conveyor means 4 are simultaneously driven by the drive motor 7, so that the wrapping bags P. P ... is carried out in a predetermined direction (see FIG. 7).

  At this time, the wrapping bag P placed on the feed roller 41 is taken up by the take-out conveyor 8 disposed along the transfer path of the feed roller 41 on the upward placement surface of the roller conveyor means 4 reversed upward. The transfer direction of the packaging bag P due to the rotation of the feed roller 41 and the transfer direction of the take-out conveyor 8 are the same as necessary, so that the moving speeds are equalized as necessary. By eliminating the relative speed difference, it is also possible to remove the bag P smoothly without being caught (see FIG. 8).

  In this embodiment, as shown in FIG. 9, the tray clamp mechanism portion 3 and the roller conveyor means 4 are disposed on the front and back surfaces of the base member 5, and the base member 5 is rotated by the turning mechanism portion 6. The lower surface and the upper surface can be alternately reversed with 61 being symmetrical, and it is also possible to configure so as to be able to process double the amount of sachets P.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims. For example, The restraining bar 42 of the roller conveyor means 4 is not limited to a sponge body, a soft rubber body, a urethane material, etc., as long as it can restrain the wrapping bag P in a buffering manner, and other plastic materials or foam materials are employed. You can also.

  Further, by changing the layout such as the mounting direction of the feed roller 41 of the roller conveyor means 4 and the tray conveying conveyor means 2, it is possible to appropriately change the transfer direction of the wrapping bag P. Furthermore, the base member 5 In addition, the tray clamp mechanism 3 and the roller conveyor means 4 are arranged on four sides, and the turning mechanism 6 is inverted every 90 ° to be able to process four times the amount of wrapping bags P. Any of these are within the scope of the present invention.
