Description

  The present invention allows the packing bag to be automatically opened and the packing bag under the strong air pressure of the air nozzle to be removed from the suction holder, and to detect the opening failure of the packaging bag in advance. The present invention relates to a bag filling and packaging apparatus.

The present applicant has developed a bag packing and packaging apparatus (see Patent Document 1) as a prior art. In this known technique, the upper surface of the packaging bag is adsorbed and held by an adsorption holder that moves up and down at the upper portion of the bag holder, and a weak wind is supplied from an air nozzle to make a preliminary opening from the bag mouth portion of the packaging bag. A bag opening holder is inserted into the bag, and air from the air nozzle that hits the bottom end portion of the bag opening holder is blown into the bag from the bag mouth portion in a strong wind state to open the entire packaging bag and into the bag. The filling material is packaged through an opening holder.
However, since there is no means for preventing the bottom surface of the packaging bag from drooping when blowing from the air nozzle in a strong wind state, that is, there is no restriction means for restricting the opening state of the bag mouth, drooping increases, and the tension increases the outside of the suction cup. There was a problem that peeling occurred from the peripheral edge of the side and the packaging bag was finally detached from the suction holder.
In addition, in the method in which the package body in which the packing material is automatically packed is simply brought into the next process manually, the package body is not transferred in the same direction as the transfer direction of the supply conveyor, but the total length of the supply conveyor is increased. With a width that fits, the structure that receives the package facing multiple bag-opening holders is compact and economical, and it is possible to save labor by handling workers in their standing positions for bagging defects and troubles. It can be done.

An electric alarm circuit is connected between the bag opening restriction plate and the bag opening holder.

The bag filling and packaging apparatus of the present invention is a compact overall structure that fits within the length of the supply conveyor in the transfer direction and is moved up and down and back and forth. Face to face, it is possible to receive a package in which the filling material is packed, so that the work is performed in a narrow range at the standing position, which is labor-saving and the work cost is reduced.
A carry-out table is provided between the suction holder and the bag holder so that it can move forward and backward, and a bag mouth opening restriction plate is provided at the forward end of the bag so that it can be moved up and down. Even when air is blown through the holder in a strong wind, the lower surface is supported by the bag opening restriction plate, so the suction surface of the packaging bag is always stably secured against the suction cup of the suction holder. Therefore, stable adsorption holding is achieved.
In addition, since an alarm circuit for applying a weak current to the bag opening restriction plate and the bag opening holder is provided, the bag opening holder is not inserted into the packaging bag, and the bag opening holder is located outside the bottom of the packaging bag. In the case of the exposure state, the alarm circuit is closed and an alarm is sounded, and it can be confirmed in advance that a bagging failure will occur, and economic loss can be minimized.

It is a front view for description of the bag filling and packaging apparatus A of the present invention. It is an AA arrow top view of FIG. It is explanatory drawing of the bag opening restriction board in this invention. It is explanatory drawing of the opening control state of a packaging bag.

An embodiment of the bag filling and packaging apparatus A of the present invention will be described in detail with reference to the accompanying drawings.
As shown in the front view of FIG. 1, a supply conveyor 3 is arranged on the left side of the figure with a bag holder 2 for stacking and storing the packaging bags 1, and a carry-out table 4 is arranged on the right side. .
The carry-out table 4 is guided by a guide rail 5 as a forward / backward moving mechanism, joined to a rod 7 of a forward / backward moving cylinder 6 and operated so as to freely move back and forth in the direction of the arrow.
Above the bag holder 2, a suction holder 8 with a vertical movement mechanism is disposed so as to be movable up and down.

The required number of bag opening holders 9 disposed endlessly on the supply conveyor 3 are each sprayed with air from the air nozzle 10 at appropriate positions (three in this embodiment), from the bottom surface of the bag opening holder 9. The deflected air opens the bag mouth portion 11.
Further, during the bag filling process, the bag opening holder 9 is held at a required advancing position by a clamper 12 that moves up and down by a lifting cylinder 13 of a vertical movement mechanism. At this time, a weak current of an alarm circuit is transferred from the clamper 12 to each bag opening holder. 9 is energized.

On the other hand, as shown in the plan view of FIG. 2, a lift plate 15 that is lifted and lowered by a lift cylinder 14 of a vertical movement mechanism is guided to the forward end of the carry-out table 4 so as to be lifted and lowered. A number of bag opening restriction plates 16 corresponding to the respective bag holders 2 are joined via elastic members.
The upper surface of the carry-out table 4 is an inclined surface that is slightly lowered toward the rear carry-out side, and an L-shaped stopper 17 is provided at the inclined end portion over the entire width.

Next, the operation of the bag packing apparatus A according to the present invention will be described in detail with reference to the accompanying drawings.
The bagging and packaging apparatus A configured as described above has the suction holders 8 lowered toward the bag holders 2 facing below in the state where the carry-out table 4 of FIG. The upper surface of the packaging bag 1 is adsorbed by the sucker and rises to the rising end.

  Next, the bag mouth portion 11 is preliminarily opened by the weak wind blown from the air nozzle 10 to the tip of the bag opening holder 9, and the bag mouth holding tongue piece 18 is rotated as shown in the explanatory view of FIG. When the upper end side of the bag mouth portion 11 of the packaging bag 1 is clamped by the bag mouth holding tongue piece 18 and the bag presser seat 19 of the suction holder 8, the bag opening opens when the carry-out table 4 advances to the forward end in this state. The holder 9 is inserted from the bag opening 11 of the packaging bag 1 as much as necessary, and the entire packaging bag is opened in a strong wind state by the air from the air nozzle 10.

Then, the clamper 12 is lowered to hold the bag opening holder 9 in the energized state, and the three bag opening holders 9 are fixed. At that time, the lifting cylinder 14 of the carry-out table 4 is in the energized lifting plate 15. Each bag opening restriction plate 16 in an energized state joined to the elevating plate 15 is pressed against the lower surface of the packaging bag 1 at the tip of each bag opening holder 9.
At this time, when the packaging bag 1 is not stored in the bag opening holder 9, the lower surface of the bag opening holder 9 and the upper surface of the bag opening restriction plate 16 are in contact with each other to close the alarm circuit. A buzzer as one means sounds and the operator can detect a state where the packaging bag 1 is not held in the bag opening holder 9 and can restore the normal state.

  When opening the bag mouth, as shown in the explanatory view of FIG. 4, if the opening state of the bag mouth portion 11 of the packaging bag 1 is regulated by the bag mouth opening regulating plate 16, it is not an enormous opening indicated by a virtual line, but an elliptical shape. The tension in the horizontal direction acts on the peripheral edge of the suction cup, the suction state is stabilized, and the packaging bag 1 is not detached from the suction holder 8.

  When the opening state of the bag mouth portion 11 is normally secured in this way, all the bag opening holders 9 are released from being held by the clamper 12 by the ascending operation by the elevating cylinder 13, and then the bag opening holder 9 is further required. Here, the filler is guided to the bag opening holder 9 and the filler is pushed into the bag by a pusher (not shown).

After the bag opening holder 9 is pulled out, the pusher moves backward, the packing material is packed in the packaging bag 1, the suction of the suction holder 8 is released at the same time as the bagging is completed, and the filling dropped on the carry-out table 4 The packaged body is received by the stopper 17 of the carry-out table 4 and is collected by the operator's hand on the carry-out side of the retracted end of the carry-out table 4 and brought into the next process.
While the carry-out table 4 is on the carry-out side of the retracted end, the suction holder 8 is lowered and sucks and lifts the packaging bag 1 from the bag holder 2, and the bag is sequentially packed by repeating the above-described procedure. .

  Thus, the bag opening restriction plate 16 eliminates the detachment of the packaging bag 1 from the suction holder 8 due to the strong wind of the air nozzle, and can receive and process the packaging body facing the plurality of bag opening holders 9, It is extremely economically useful in that it is labor-saving for the operator, such as being able to deal with troubles in a standing position on the spot, and that it can be efficiently packed with a compact structure.

The vertical facing of the suction holder 8 and the bag holder 2 in which the packaging bags 1 are stacked and stored by the vertical movement mechanism in the present invention covers one or more pairs, and therefore, between the suction holder 8 and the bag holder 2. The carry-out table 4 that is moved forward and backward by the forward / backward movement mechanism also has a required width corresponding to the opposite logarithm, and the bag mouth opening restriction plate 16 that is disposed at the forward side end portion so as to be movable up and down by the vertical movement mechanism Corresponding to the number of suction holders 8, each one is operated simultaneously.
Further, the detection means in the alarm circuit can be provided by light, abnormal vibration, or the like in addition to a buzzer or sound.
The bag opening restriction plate 16 may be attached to the lifting plate 15 through an elastic conductive material (spring or the like), in addition to being exchangeable with each other.
