[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag discharging device for a vacuum packaging machine for foods and the like.

[0002]

2. Description of the Related Art FIG. 3 shows an outline of a conventional automatic packaging system, which comprises a filling device A for filling a bag 1 with a filling and a vacuum packaging device B for vacuum-treating the bag 1 containing the filling. Become. In the filling device A, the bag 1 in the storage box M is picked up, and while being held by the chuck 2, the table T ₁ is intermittently rotated and the filling is stored in the bag 1, and one step before the final step of the one rotation. It is delivered to the vacuum packaging device B at (section 7 in the illustrated example).

In the vacuum packaging apparatus B, however, the bag 1 is housed in the vacuum chamber 3, and after the table T ₂ is intermittently rotated, the vacuum processing and the bag mouth sealing processing are performed, and then the final step 1 of the one rotation is performed. Previous step (section 1 in the illustrated example)
In 1), it is taken out from the vacuum chamber 3 and discharged to the next step.

[0004]

In the above, the bag 1 is gripped by the chuck in the vacuum chamber 3 and vacuumed and sealed in a suspended state. FIG. 4 shows the gripped state. The bag 1 is clamped at both upper ends of the bag by chucks 2 composed of movable claws 2a and 2a and fixed receiving portions 2b and 2b. The rod 5 reciprocates in the directions of arrows (a) and (b) by the rotation of the cam 4, and the opening and closing operations of the arrows (c) and (d) are performed through the crankshaft 6, so that the grasped bag 1 is released. When doing so, the movable claws 2a, 2a are opened as shown by the dotted lines in the figure, dropped onto a conveyor (not shown), and discharged to the next step.

By the way, the sealing of the bag mouth is carried out by pressing the heat plates 18 from both sides of the bag through Teflon sheets and fusing them. However, when the bag 1 is light, the bag 1 is welded to the Teflon sheet. Alternatively, even if the movable claws 2a and 2a are used, the bag 1 may not drop due to the adhesive filling adhered to the movable claws.

By the way, conventionally, as shown in FIGS. 5 and 6, the receiving plate 7b is pushed by the push rod 7a attached to the tip of the cylinder 7, the base plate 8 is rotated around the shaft 9, and the bag 1 is chucked by the end plate 8a. It is pushed away from 2 and dropped. However, such a method has a problem that the bags dropped on the conveyor are placed in irregular postures, which hinders the work of the next process.

The present invention is intended to solve the above-mentioned problems, and is characterized in that it has a large number of vacuum chambers each having a mechanism for holding a bag containing a filling in a vertical state. A vacuum process and a sealing process are sequentially performed by intermittent rotation of the table, and at the end position of one rotation, that is, in the front position of the process of discharging the bag from the released vacuum chamber, in relation to the intermittent rotation of the table. Attach the arm that moves forward and backward in the horizontal direction to the upper end of the drive shaft built into the stand,
A suction plate is attached to the tip of the arm through a rod which is also horizontal in a state orthogonal to the suction plate, and the forward movement of the suction plate causes the suction plate to come into contact with the vertical front surface of the bag to suck and fasten it. At the lower position in the backward movement trajectory of the above, a slide table is attached through a stand separately provided so that its height and inclination angle can be adjusted appropriately, and the suction front secures its vertical front surface. The vacuum of the suction plate is cut off and dropped onto the inclined upper surface of the sliding table.

[0008]

A bag discharging device including a suction cup and a sliding table is provided at the bag discharging position of the vacuum packaging machine, and the bag can be securely gripped by the suction disk and properly dropped onto the sliding table.

[0009]

1 is a plan view of the device of the present invention, and FIG. 2 is a side view thereof. Reference numeral 10 is a stand that is erected at a front position of the bag discharging process of the vacuum packaging machine, and has a drive shaft 11 vertically installed therein. The drive shaft 11 is interlocked with the intermittent rotation of the table T ₂ and driven by a motor (not shown) to reach the shaft end. The fixed arm 12 is pointed toward the bag 1 held by the chuck 2 on the front surface of the table T ₂ by an arrow (e).
(F) The rocking action is performed. Thirteen
The sucking rod attached to the tip of the arm 12 sucks and holds the bag 1 by suction means (not shown) when the suction cup 13a at the tip comes into contact with the bag 1 by the forward movement (e) of the swinging action.

Simultaneously with the suction stop of the suction cup 13a, the gripping claws 2a, 2a of the chuck 2 are released, and the arm 12 is moved backward (f) so that the bag 1 is fixed to the suction suction while keeping the bag 1 vertical on 13a. Retreat in the state.

Reference numeral 14 denotes a slide table which is arranged in the locus of the backward movement of the arm 12, and which is mounted on the stand 15 through a bracket 16 at an appropriate height and at an appropriate inclination angle by a pin bolt 16a. The discharge conveyor 17 and the bag 1 in which the suction cups 13a are fixed by suction between them
I will deliver it.

The apparatus of the present invention has the above-mentioned construction, and the bag 1 which has been subjected to the vacuum treatment and the sealing treatment in sequence with the intermittent rotation of the table T ₂ comes to the position shown in the figure and stops, and the door of the vacuum chamber is opened. The drive shaft 11 rotates, and the arm 12 moves forward in the arrow (e) direction to move the suction cup 1 at the tip of the rod 13.
3a is brought into contact with the bag 1, and the bag 1 is suction-fastened by the suction cup 13a.

Therefore, in relation to this, the chuck claws 2a,
2a is released and the arm 12 moves backward in the direction of the arrow (f), the vacuum of the suction cup 13a is released at a position above the slide base 14 and the bag 1 is dropped vertically, and the bag 1 is transferred to the discharge conveyor 17. It is configured so as to slide down while falling, and the fall distance L of the bag 1 onto the slide table 14
The inclination angle θ is appropriately changed according to the size and contents of the bag 1, and the dropped bag 1 slides a certain distance on the slide table in a good state, and is properly positioned on the discharge conveyor. And will be sent to the next process.

[0014]

As described above, according to the device of the present invention, the bag 1 sent in the bag discharging process in the vacuum packaging machine is surely adsorbed and grasped by the suction cup 13a while being kept vertical, and desired. It can be carried and dropped on a slide in a specific place,
At that time, the slide table can roll the bags in a constant and good condition while tumbling and handing them over onto the discharge conveyor. Therefore, the bags are respectively arranged on the conveyor in the correct posture and regularly. In this state, it is carried out to the next process, and the work of the next process can be smoothly performed without any trouble.
