Description

[Detailed description of the device]

[Field of Industrial Application] [0001] The present invention is a product (eg pickles) which may leak water or odor in a supermarket when shipping fresh foods at a production site or an accumulation site for vegetables and seafood. , Seafood, meat, detergents, insect repellents, frozen desserts, etc.), or floors and products get wet in the rain in department stores, hotels, airports, theaters, and other facilities where an unspecified number of people enter and leave. The present invention relates to a "bag opening device" which is devised so that the work can be performed quickly and easily when putting a umbrella in an umbrella bag provided to prevent such a situation.

[Prior Art] Conventionally, for the purpose of the above, as a bag, a bag made of thin polyethylene having a thickness of about 0.005 to 0.05 mm has been used. In the state, it was as if the two sheets were tightly stuck together, and it was not easy for humans to open each item quickly when inserting an article or umbrella. Therefore, the inventor of the present invention has already devised, as a countermeasure, an "polybag automatic opening device" that opens using an air flow (Japanese Patent Application No. 4-248500).

[Problems to be Solved by the Invention] However, when the conventional lifting device is used, there are the following problems. When inserting articles into the bag, it is necessary for a human to set the bags one by one on the table of the device. The places where agricultural products and marine products are handled during rainy weather are usually subject to water wetness, and when it rains, the humidity is high and the bag sheets tend to stick to each other. Bag opening tends to be uncertain. Therefore, the present inventor should open the bag securely and quickly when inserting the article into the bag, without the need for humans to set the bag on the machine one by one and even in the working environment described above. I decided to develop a device that can do this. At that time, the design policy adopted by the present inventor is as follows. a. A plurality of bags bundled in advance are set on the device. b. As the bag, one having a tongue portion (ear-like protruding portion) is used for locking to the device and for guiding when inserting the article. c. Instead of using the air flow, the bag opening method will use a gutter-shaped insertion article loading platform that has a tip shape that facilitates entry into the mouth of the bag.

[Means for Solving the Problems] In the device of the present invention, the following measures were taken to address the above problems. Basically, in order to keep a large number of tongue bags in a bundled state, the same as above, the bag holder equipped with the tongue locking device and the mouth of the bag to be opened. A gutter-shaped or scoop-shaped article mounting table having a tip-like shape (for example, a streamlined shape as shown in FIG. 3) is provided. The bag loading table and the article loading table shall be placed on the extension lines of the mutual longitudinal direction, and the article loading table shall be locked to the main body of the device, while the bag loading table should be placed in the direction of the article loading table and in the opposite direction. The drive mechanism provided in the main body of the apparatus allows the user to move the apparatus according to the intention of the user of the apparatus, if necessary. However, in this case, the drive source may be a foot pedal, a hand lever, etc., a motor, a solenoid, pneumatic pressure, hydraulic pressure, or any other method. By the above drive mechanism, the bag placing table is pulled toward the article loading table, and the tip of the article loading table is slid over the tongue portion of the bag with the tongue placed on the bag placing table to enter the mouth of the bag. Open the bag so that the articles placed on the article mounting table can be easily inserted into the bag.

Incidentally, the reason for fixing the article mounting table and moving the bag mounting table in this apparatus is as follows. If the article loading table is to be moved, the articles to be inserted into the bag must be firmly pressed on this table. Otherwise, the articles may inertially slide backwards when the platform is moved rapidly towards the bag. In addition, if the article is pressed down strongly to prevent it, the movement of the mounting base becomes worse, and the fact that the first moving body is touched by itself is bothersome and dangerous.

The tongue bag used in the present invention means a bag provided with a protruding portion adjacent to the opening, that is, like an ordinary envelope. There are no particular restrictions on the material of the bag, but in view of economy and water resistance, the same material as that of the bag usually used for preparatory packaging in supermarkets, that is, plastic such as polyethylene may be used. Also, of course, plastics such as polyvinyl chloride, polypropylene, polybutadiene, polyvinylidene chloride, polyethylene terephthalate (PET), ethylene-α olefin copolymer, waterproof paper, plastic laminated with aluminum foil, paper, etc. May be The thickness of the sheet as a bag material may be about 0.005 to 0.05 mm.

The locking of the tongue may be performed by any method, but a method using a locking tool as described below is conceivable as a method for simplifying the operation. The tongue part is held by a clip (clip) or the like provided on the bag mounting table. Insert the pins, bolts, rings, strings, etc., provided on the bag mounting table, into the holes provided in the tongue to engage them. Here, in the case of pins and bolts, after setting the tongue part, a pressing plate (having a hole or a U-shaped groove) is superposed on the tongue part to secure the bag more securely. Is good. In this case, it is desirable that the pressing plate be connected to the bag mounting table portion by a link or the like so that the tongue portion is pressed by the spring force. However, in the case of bolts, the link above may be omitted and the retaining plate and spring fitted on the bolt may be tightened with a wing nut or the like. In the case of a ring, of course, it is opened once, and after passing through the hole in the tongue portion, it is closed again in a ring shape. The method of using the string is self-explanatory and will not be described.

By the way, although the tongue portion is usually provided with only one hole (see FIG. 1 (a)), the number of holes should be two or more in order to more securely fix the bag. Be free. In addition, it is free to use the same hole size or a combination of different holes. In this case, naturally, a plurality of pins and bolts are required. In addition, in order to make it easier to peel the bag body, there is no extra tongue part attached to the bag body unnecessarily, and to prevent the thickness change of the tongue part that is stacked and bound. As shown in Fig. 1 (b), it is desired that perforations be inserted in the tongue. However, if a perforation is to be made in this way, the tongue can be held by a holding tool, and the holes in the tongue and pins in the device can be omitted (see FIG. 1 (c)).

[Embodiment] Next, the configuration of the present apparatus will be described based on the embodiment of FIG. In the figure, a bag placing table 1 is arranged at the left end, and a tongue-filled bag 3 is placed on the bag placing table 1 with the mouth portion 4 facing rightward (toward the article loading table 7). The bag is held on the placing table by locking the tongue portion with the tongue engaging member 2 of the bag provided at the end of the bag placing table on the side of the article loading table (in this example, a hole is provided). A bag with a tongue is used, and a locking pin with a screw, a washer, and a wing nut are used to lock the tongue). A movable table 6 having wheels 13 is coupled to the bag mounting table 1, which is arranged on both sides of the movable table 6, and is guided by channel-shaped guide rails 12 fixed to the apparatus main body. Further, the above-mentioned moving table is driven by an L-shaped lever 18 which is rotatably engaged with a stay 16 and a pin 17 provided on the apparatus main body.

The movable table 6 and the L-shaped lever 18 are engaged with each other by engaging a pin 15 provided on a stay 14 attached to the table and a guide groove 19 provided on the lever. However, in this case, the stay is not always necessary, and the guide groove may be engaged with the axle of the wheel 12. The bag placing table is driven by a foot pedal 20 provided at the free end of the lever. In other words, by stepping on the pedal, the moving table 6 moves to the right side of the figure, and the bag loading table 1 coupled to it moves toward the article loading table 7. Then, the tip 8 of the article loading table slides on the tongue portion 5 of the bag while appropriately pressing the tongue portion 5 of the bag and enters the mouth portion 4 of the bag to open the bag.

By the way, the article mounting base has a hinge provided at the bottom and is configured so that the front end "bows", but the tongue of the bundled bag has a compressibility to some extent. This is to cope with the fact that the overlapping thickness of the tongue portion is gradually reduced due to the tearing-off operation of the tongue portion that is performed each time the article is inserted. That is, such a structure is adopted so that the tip of the article mounting table can be surely opened by pressing the tongue portion toward the mouth of the bag. In the example shown in the figure, the tension spring 11 is provided under the article mounting table. This is to adjust the pressing force of the bag tongue by the tip of the article mounting table and to prepare the article loading table during operation. It is intended to prevent sudden jumps and is not always necessary. By the way, in the example shown in the figure, the product mounting table is set slightly upward to the right, but this is to allow the tip to smoothly enter the mouth of the bag. It is set at 5 °. However, this angle α should be appropriately determined experimentally in consideration of factors such as the tip shape and material of the article mounting table, the thickness and material of the bag material, and the pressing force by the tip of the article mounting table. Yes, it is set in the range of 0 ° to 30 °.

[Advantages of the Invention] In the bag opening device according to the present invention, a large number of tongue-filled bags are bundled and set in advance on a movable bag mounting table. In addition, this platform can be moved to the article loading platform that is locked to the main body of the equipment by the operation of the foot pedal, etc., so that the mouth of the tongue bag is automatically opened at the tip of this article loading platform. To be Therefore, the user of this device does not need to set the bag in the device each time when packing the article, and after opening the bag automatically by the machine as described above, the item on the article loading table is not packed. If slipped in, bagging can be accomplished quickly and easily. Therefore, according to the device of the present proposal, when packaging products at the place where agricultural products are produced or sold such as supermarkets and supermarkets, or when it rains, bags of umbrellas are used at the entrances of department stores and hotels. Very smooth operation is guaranteed, such as when providing a closing service.
