Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is for making a bag in a vertical packaging machine for producing coffee, tea, dashi (granular) packaging bags, etc., and when packaging product bags and small bags such as freshness-retaining agents in an outer packaging bag. Related to the automatic charging device. In the present invention, the "product bag" is a bag in which food or the like is packaged, and the "small bag" is a bag of oxygen absorber and / or carbon dioxide absorbent, a bag of desiccant, a bag of ethylene gas absorbent, etc. It refers to a bag in which powder or granules or tablets are packed. Also, "small bag" is sometimes called "small bag of freshness-retaining agent".

[0002]

[Prior Art]

 Conventionally, for example, in a two-stage vertical pillow packaging machine such as an automatic tea bag gas filling packaging machine, a tea bag or a coffee bag is produced by interlocking with an automatic weighing machine in the preceding packaging machine, and then this. Is moved horizontally or vertically, and is charged from the raw material charging port of the packaging machine for the outer packaging at the latter stage, and is automatically packed by the outer packaging material while gas filling. In recent years, when using this type of packaging equipment, not only freshness retention using the inert gas filling method, but also small bag such as freshness-retaining agent is thrown into the outer bag together with the product bag when filling the outer bag. Methods for maintaining the freshness or stability of quality of products have come into the limelight.

[0003]

[Problems to be solved by the device]

 However, when filling the outer bag with a small bag such as a freshness-retaining agent in the above-described two-stage vertical pillow packaging machine, products such as a tea bag or a coffee bag are supplied from the inlet provided in the packaging machine. It is put in the bag at the right time, but in many cases, this small bag of freshness-retaining agent causes so-called "biting" in the heat-sealing part of the outer bag, which causes trouble, which is a practical problem. Is coming.

Needless to say, the "bite phenomenon" of the heat-sealed portion causes a lot of other damages such as poor sealing of the packaging material, poor freshness retention, damage to the packaging material, and damage due to damage. . In order to eliminate these inconveniences, it was necessary that the product bag and the small bag such as the freshness-retaining agent be simultaneously loaded from the loading hopper and at least two bags be dropped at the same time as much as possible.

[0005]

[Means for solving problems]

 In order to achieve the above purpose, a special shutter mechanism is installed in the hopper for loading product bags and small bags such as freshness-retaining agent. They are allowed to stay, and then these are added at the same time. Depending on the type of product, it was devised to further prevent vibration of the outer surface of the outer packaging material to prevent sealing defects such as "bite" in the outer bag heat seal part or "wrinkle" in the heat seal part.

That is, the present invention provides a vertical wrapping machine in which a product bag and a sachet are loaded into the wrapping machine, and at the same time in the hopper immediately before the product bag and the sachet are loaded into the vertical wrapping machine. The present invention relates to an automatic closing device provided with a shutter that can stay once and overlap with each other, and then opens and closes in response to an operation signal. Furthermore, the shutter of the automatic closing device is air or electromagnetic drive, and packaging Machines that operate with a synchronous signal during automatic operation of the machine and have a timing adjustment function, or when loading the product bag and sachet into a vertical packaging machine, apply vibration to the outer surface of the packaging material under the automatic loading machine. The present invention relates to an automatic charging device having a mechanism for imparting it.

According to this invention, the following is possible. That is, the product bag (the front-stage packaging product) sent from above (the front-stage vertical pillow packaging machine) and the small bag thrown from the chute are temporarily stored in the throw-in hopper (built-in automatic throwing shutter) to form the product bag. It absorbs the slight timing difference due to the overlap with the pouch. As a result, product bags and sachets are stably supplied in the outer bag in the latter packaging machine.

Various types of automatic closing shutter mechanisms are adopted. For example, a flat plate attached to the shaft (the shape can be variously selected depending on the shape of the hopper) is opened and closed by the rotation of the shaft, and its drive Methods include air cylinder drive and electromagnetic drive, which are activated by the synchronization signal of the packaging machine.

The above technical means operate as follows. The product bags and pouches loaded into the loading hopper are automatically sealed by the automatic loading shutter opened by the synchronization signal of the packaging machine after the longitudinal (flow direction) sealing and the lower sealing of the outer packaging machine in the latter packaging machine are completed. , Stable and simultaneous supply into the outer bag. The outer bag is packaged by repeating this cycle.

Depending on the type of product bag or pouch, the dropping speed may be different. When the bag is put into the exterior bag, the side surface of the exterior packaging material is vibrated by a vibrator or a vibrating rod, so that the product bag is not Prevents the pouches from overlapping vertically without overlapping.

[0011]

【Example】

 The present invention will be described with reference to embodiments (drawings). The product bag 14 drops into the loading hopper by the automatic operation and automatic loading of the upstream packaging machine, while the small bag 15 also slides down the chute 3 by the synchronization signal of the downstream packaging machine, and each is automatically loaded into the loading hopper 2. At this time, the automatic shutter 16 (see FIG. 2) installed in the input hopper 2 is closed. At the same time as the automatic operation timing of the packaging machine, the product bag 14 and the pouch 15 that are temporarily staying in the loading hopper 2 at the same time are put into the outer bag at the same time by opening the automatic loading shutter 16. At this time, the vibrator 11 vibrates the side surface of the exterior packaging material 6 almost at the same time as the feeding operation to prevent the pre-stage packaging pouch (product pouch 14) and the pouch 15 from being vertically connected. . After that, the upper part of the outer packaging bag (which will be the lower surface in the next process) is sealed to complete one packaging process. This is continuously operated automatically by the synchronization signal from the latter-stage packaging machine.

[0012]

[Effect of the device]

 As described above, the present invention not only properly supplies the product bag and the small bag into the outer packaging bag, but also exhibits the following excellent effects. 1) Inconvenience caused by product bags or sachets that overlap each other at the same time and do not fall in a row, and one or two of these are present in the seal part (opening) of the outer packaging bag and then cut (exterior) It is possible to prevent problems such as poor sealing of packaging bags and contamination of the surrounding area due to cutting of product bags and sachets. 2) Cleaning work due to the occurrence of the above troubles, work stoppages for preparations for restarting operations, etc., and production reduction due to this are prevented. 3) Defective products in the outer packaging bag can be prevented and quality assurance for customers and reliability can be improved.
