Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention provides packaging bags of a specific size (hereinafter referred to as
The present invention relates to a bagging guide device suitable for packing articles of variable shape, such as processed foods such as sausages and hams, into bags (referred to as bags).

(Prior art) Conventionally, sausages, hams, etc., which are made mainly by hand to shape the final shape, have different cross-sectional shapes of individual parts, even if the general shape is the same. Even if the product is a type of product, the size and shape of each part of the product often vary.

Therefore, when packaging this type of item as a product in a bag, a bag that is sufficiently spacious compared to the size of the item is often used.

(Problems to be Solved by the Invention) As mentioned above, when packing many articles whose cross-sectional shapes are not uniform, if the size of the bag is unnecessarily large compared to the size of the articles, This makes the packing process easier, but the bag does not only hang around the product after packing, damaging the product's appearance.
This often causes problems in handling the goods, and there are also problems such as the bag being easily damaged.

This invention has been made in view of the above points, and even if there are differences in the dimensions of each part of the article, it is possible to pack the article using a bag that matches the size of the article, regardless of this difference. The purpose is to provide a guidance device.

(Means for Solving the Problems) The gist of the present invention to achieve the above object is to mount a plurality of bag opening opening mechanisms at equal intervals around an annular underframe having a hollow hole. The bag opening opening mechanism includes a parallel link whose base end is pivoted to the underframe toward the center of the inner hole of the underframe, and a bag opening stopper piece that is vertically attached to the tip of the link facing the center of the underframe. A bag filling guide device is provided, comprising a link biasing means for biasing a bag opening piece toward the center of the frame in a normal state.

(Function) Therefore, according to the present invention, the bag opening of the bag in which the articles are packed is slightly opened and the bag opening opening mechanism, which is clustered near the center of the inner hole of the base frame, is opened. By inserting each contact piece and pushing down each bag opening expansion mechanism as the article is inserted into the inner hole, each of the contact pieces individually moves in parallel in the direction of separation from each other, and the bag opening moves as the article passes through. To expand the surroundings and pack items into bags without difficulty.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a plan view with a part of the invention removed, FIG. 2 is a vertical cross-sectional view of the main part, and FIGS. 3 a, b, and c are explanatory views of usage.

In the figure, reference numeral 1 denotes a ring-shaped underframe, which has a hole 2 large enough for the article A to pass through.
It is supplied from above. Reference numeral 3 designates a plurality of bag opening expansion mechanisms that are equally spaced around the underframe 1, and the bag opening expansion mechanisms 3 include a parallel link 4 that has its base end pivoted on the underframe 1, and a parallel link 4 that faces the center of the underframe. It consists of a bag mouth piece 5 hanging from the tip of the link, and a link biasing means 6 that normally biases the bag mouth piece 5 toward the center of the hole,
By swinging the parallel link 4 in the vertical direction, each bag opening piece 5 moves toward and away from a position near the center of the underframe, parallel to the central axis of the hollow hole of the underframe 1, while maintaining mutual parallelism. .

In the embodiment, the link biasing means 6 described above includes a spring 7 stretched between the underframe 1 and the parallel link 4, and a balance weight 8 attached by extending the base end of the link rearward.

Reference numeral 9 denotes a guide tube made of a flexible material such as a vinyl sheet material, which is attached in communication with the inner hole 2 of the underframe 1, and the upper end is replaced by a retaining ring 10 around the inner hole 2 of the underframe 1. is freely attached, and the lower end is inserted into the bag opening opening mechanism 3 in a free state.

In the figure, reference numeral 11 denotes a locking protrusion provided on the outer surface of the bag opening piece 5, which is locked to the bag opening B1 of the bag B from the inside thereof.

Reference numeral 12 denotes a contact plate fixed on the parallel link 4, which is fan-shaped and serves to reduce the gap between adjacent parallel links and to smoothly transmit force from the article side to the parallel link 4.

In the above configuration, the manner in which articles are packed in bags will be described with reference to FIG.

As shown in Figure a, the bag opening expansion mechanism 3 is in a normal state, that is, the parallel link 4 is in a substantially horizontal position, and each bag opening piece 5 is gathered near the center of the hollow hole. Bring the bag B to be stored below the device, open the bag mouth B1 slightly by blowing air into the bag mouth B1, and when the bag mouth B1 is opened, lift the entire bag up. , the bag mouth piece 5, which is gathered near the center of the inner hole, is inserted into the bag mouth.

Next, as shown in FIG. The bag opening pieces 5 move in the direction of separation from each other, and are engaged with the inside of the bag opening B1 to open it.

When the article A is further pushed in, as shown in Figure c, each bag opening piece 5 moves in proportion to the force from the article side under the downward rotation of the parallel link 4, and the bag opening B1 Expand the bag and pass article A into the bag without force.

Incidentally, when the article A is packed in a bag, the movement of the parallel link 4 that is pushed by the article A is controlled by the link biasing means 6.
However, in this case, the link biasing means 6
As for the resistance force, at the initial stage when the parallel link 4 starts to move downward from its normal position, which is approximately horizontal, the influence of the lifting of the balance weight 8 is large, and gradually the elasticity of the spring 7 becomes stronger. It becomes like this. Furthermore, when the parallel links 4 return to their original state after the article A has entered the bag, the link biasing means 6 operates based on the above-mentioned reverse order.

(Effect) As described above, according to the present invention, when packing articles into bags, the bag opening flaps of the bag opening opening mechanism inserted into the bag opening are inserted into the bag opening at multiple locations around the bag opening to the minimum necessary amount. Since the bag is pushed open to allow the items to pass through, it is easier to open each part of the bag compared to opening the entire bag wide and filling the bag.
The opening of the bag can be rationally opened in each direction according to the cross-sectional shape of the item, providing great flexibility, and the bagging process can be easily carried out by using a bag that is sized to match the size of the item. It is carried out smoothly and there is no bagging after bagging, which improves the appearance of the product and has practical effects such as no problems caused by bagging.
