Abstract

PURPOSE:To eliminate troubles such as flowing-out of contents or defective sealing arising from defective holding of pouches by a method wherein positions of the held pouches are detected, and controls are executed to stop operations on the following processes after the next for the pouches that are not held in correct position. CONSTITUTION:Each of pouches taken out one after another, being sucked by a sucking disk or the like, from a pouch stand 2 is held correctly with grippers at both ends near its end on the openingside, and is sent to stages of processes after the next, including a mouth opening stage 4, a filling stage 5, a sealing stage 6 and a cooling stage 7, and sent out to a carrying-out stage 8. In the case where defective holding is detected in a position-detecting stage 3 for any of the pouches, signals are sent from the position-detecting stage 3 in consecutive order to the following stages of processes so that the pouch for which defective holding is detected can be sent, passing by all of the following stages of processes and sent out to the carrying-out stage 8 without undergroing any of the processings, and driving for every stage of processes can be controlled automatically with a sequencer or the like. Thereby, troubles such as flowing-out of contents or defective sealing can be prevented, and the pouches found to be defectively held become reusable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to automatically produce a substance having fluidity, such as a fluid, a powder or a granular substance, automatically.
The present invention relates to a bag feeding type automatic continuous filling (packing) device for continuously filling and sealing a pouch.

[0002]

2. Description of the Related Art In recent years, in the industry of food, medicine or cosmetics, it is possible to replace solid containers such as conventional cans or bottles at low cost and to dispose of them, and also to reduce waste from environmental problems. There is an increasing tendency to utilize flexible pouches that allow the empty pouches to be transported and stored.

There are two types of pouches, a flat pouch in which two sheets on the front and back are simply superposed and closed at two or three sides thereof, and a so-called self-standing pouch in which a gusset-like sheet is joined to the bottom. These pouches have, as a filling port, an open end that is open over substantially the entire width. On the other hand, as a bag feeding type automatic filling (packing) device, all the steps such as taking out the pouch from the bag stand, opening with a molding cone, filling, internal deaeration, closing, sealing, cooling, and sending out are automatically performed. A device is widely known, and its description is found in, for example, Japanese Patent Application No. 5-199281.

In these bag feeding type automatic filling (packaging) devices, in order to smoothly perform a series of steps after taking out the pouch from the bag stand, a method of gripping both ends near the open end of the pouch is generally adopted. . That is, both ends near the open end of the pouch are gripped, and while maintaining this state, opening of the open end, filling, internal degassing, sealing, cooling, and delivery are performed.

Therefore, it is required that the open end of the pouch be held substantially horizontal. That is, when the pouch is gripped in an inclined state, the filled substance may flow out at the time of filling, or the open end may be poorly sealed, causing problems such as leakage of contents during packaging or transportation. Further, even if the pouch is held horizontally and is vertically and horizontally shifted, it causes inconveniences in opening, filling, sealing and cooling.

[0006] As a countermeasure against this, Japanese Patent Application No. 5-1992 mentioned above
According to the specification No. 81, since the pouches on the bag stand are always aligned in a fixed position, the pouches are transferred onto the bag stand, and then the backing plate or the open end of the pouch is applied plural times to align the bags. The method is described.

Although the efficiency of the improvement can be seen by this method, it is not yet sufficient, and in the process of taking out and gripping the pouches piled up on the bag stand one by one, a slight sticking of the pouches or a distortion of the pouches causes However, the pouch is not normally gripped and the above-mentioned problems often occur, and measures from a different viewpoint have been desired.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and eliminate the outflow of the filling material at the time of filling due to the poor grip of the pouch and the sealing failure at the open end, and the automatic bag-filling type continuous filling apparatus. To provide.

[0009]

The above object of the present invention is to remove the pouch from the bag stand, grasp both ends near the open end of the pouch, open and fill the open end, and seal the open end. It is placed in a bag-feeding type automatic continuous filling device having at least, and the position of the pouch that is gripped is detected, and only the pouch that is not gripped at a predetermined position is controlled so as to stop the operation of the next process and thereafter. It was achieved by a bag feeding type automatic continuous filling device.

[0010]

That is, according to the present invention, even if the pouch is grasped obliquely, the operation of opening, filling, sealing and the like of the open end after the next step is stopped so that a defective product is not generated.

That is, a sensor such as a photoelectric sensor detects whether or not the state of the gripped pouch is substantially horizontal, and a sequencer or the like is provided so that only the pouch that is not gripped at a predetermined position passes through the subsequent process. Therefore, the means for automatically controlling the drive unit in each process was taken.

[0012]

EXAMPLES The present invention will now be described more specifically with reference to the examples shown in the drawings.

FIG. 1 is a plan view showing the arrangement of the entire mechanism of a self-supporting pouch bag type automatic continuous filling (packaging) device, and FIG. 2 is a perspective view showing a state in which the pouch is gripped.

In FIG. 1, the pouches taken out one by one from the bag base 2 by a suction plate or the like (not shown) are in a state where both ends near the open end 13 are gripped by the gripper 10 as shown in FIG. Then, around the filling table 1 which is moved by the filling table 1, there are respective steps for filling and sealing during the movement process of the pouch.

First, there is the pouch position detection unit 3 which is a feature of the present invention, and the normally held pouch has the opening 4, the filling unit 5, the sealing unit 6, and the cooling unit 7 in the subsequent steps. Although the treatment is performed in each step and is sent to the carry-out section 8, the pouch in which the gripping defect is detected by the position detection section 3 passes through all the steps after the above-described next step, and is delivered to the carry-out section 8 without being treated. As it is sent out, the signal from the position detection section 3 is sequentially sent to the subsequent steps, and the drive section of each step is automatically controlled by a sequencer or the like.

Here, the step 4, the step 5 of filling the open end of the pouch, the step 5 of filling, the step 6 of sealing the open end of the pouch, the step 7 of cooling the seal part, and the step 8 of carrying out are the means in the invention. There is no particular limitation, and it goes without saying that any method known in the art can be arbitrarily used. Further, if necessary, steps other than the above can be arbitrarily incorporated.

Next, an example of means for detecting the gripped state of the pouch is shown in FIG. FIG. 3 is a front view showing the position of the detection sensor. The reflection type sensors 11a and 11b and the transmission type sensor 1 are provided so that the inclination and displacement of the pouch 9 can be detected.
2a, 12b, 12c and 12d are arranged.

By combining the reflective type sensor and the transmissive type sensor, not only the inclination of the pouch,
Even if the pouch is displaced vertically or horizontally, it can be detected by either the reflective sensor or the transmissive sensor.

A photoelectric sensor such as an LED or an infrared ray is preferably used as the sensor, and a fiber system improves the detection accuracy.

[0020]

According to the bag feeding type automatic continuous filling (packing) apparatus of the present invention, even if the gripped pouch is tilted or deviated, it is detected and passed through the subsequent steps. There are no defective products due to outflow of filling materials during filling or leakage of contents due to defective sealing. In addition, since the pouch with poor grip is not treated in each step, it can be reused and the loss of the pouch is reduced.
