  However, conventionally, when the laver containing packaging sheet is wound around the shaver, most of it is carried out manually, so that there is a drawback that it is troublesome and difficult to apply to mass production.

  Further, in the automated seaweed rolled rice wrapping method according to Patent Document 1, the shear is automatically lowered and fitted into the upward groove by the winding belt, and then the shear is automatically lowered by the groove forming roller. Since the winding belt itself is flexible when it is wound around the laver containing packaging sheet, if the holding power of the shaving due to this is insufficient, the laver containing packaging sheet against the shaving caused by the groove forming roller At the time of winding, there is a drawback that the winding peripheral surface of the shaving winding belt is distorted and cannot be formed into a clean cylindrical shape.

  In particular, in the past, there has been a concern about the possibility of misalignment because the shaver has been dropped by natural fall onto the lower laver containing packaging sheet that has been transported to the pouring position by the turntable.

  Therefore, the present invention has been devised in view of the conventional circumstances as described above, and can be used for mass production by automating the operation of winding the laver-containing packaging sheet into the shari, and the laver for the shari An object of the present invention is to provide a food supply mechanism and a supply method thereof in a food packaging apparatus capable of efficiently producing a good-looking product, in which the shape of the sash is formed into a clean cylindrical shape when automatically encasing a packaging sheet. To do.

  In order to solve the above-described problems, in the present invention, the food supply in the food packaging apparatus provided with the food supply unit for dropping the food conveyed by the turntable conveyance mechanism onto the conveyed packaging material The food supply unit includes a gate for charging food onto the transfer mechanism by a charging mold from an input opening of the turntable transfer mechanism, and a pair of cam receiving plates integrally connected to the gate; A gate opening / closing cam that moves up and down together with the dosing mold, and before the closing mold contacts the food, the gate opening / closing cam pushes down the pair of cam receiving plates to open the gate downward. .

  The food supply unit supports the food at both ends of the gate without dropping the food until the gate is fully opened, and at the same time creates a gap between the dosing mold and the food.

  Further, in the food supply method in the food packaging device according to the present invention, the food is transported to the input opening position of the turntable transport mechanism, and the packaging material is transported to the gate lower position by the transport mechanism, Before the dosing mold and the gate opening / closing cam are lowered and the dosing mold is brought into contact with the food, the gate opening / closing cam contacts the pair of cam receiving plates to open the gate downward. At the same time, a gap is created between the dosing mold and the ingredients, preventing the ingredients from being crushed until they are placed on the packaging, and the ingredients are released when the gate is fully open. At the same time as being placed on the packaging material, the charging mold contacts the food material and presses it against the packaging material.

  According to the present invention, it is possible to automate the operation of winding the laver-containing packaging sheet into the spear and use it for mass production. , Good-looking products can be manufactured efficiently.

  Further, in the past, since it was transported to the input position of the food by the turntable transport mechanism and dropped to the lower packaging material by natural fall, there was a concern about the possibility of positional displacement, but according to the present invention By providing the food supply mechanism, the natural fall of the food can be prevented in advance, whereby the food can be reliably arranged on the packaging material while correcting the positional deviation. Moreover, at this time, there is no risk of the food being crushed.

The best mode for carrying out the present invention will be described below with reference to the drawings.
The reference numeral 1 shown in the figure is used to wrap a substantially cylindrical food material P having a material in the center with a wrapping material S such as a thin-film flat laver containing packaging sheet made of plastic or the like. This is an automated food packaging device.

  As shown in FIG. 7, the packaging material S is formed in a thin flat bag shape with a material such as plastic so as to accommodate a rectangular dried seaweed Q. Both side ears S1 having a substantially rectangular sheet shape for covering both end portions of the two are projected so as to form a substantially T-shaped sheet as a whole.

  As shown in FIG. 1, the food packaging device 1 includes a pair of front and rear endless belt-like transport mechanisms V that are intermittently slidable, which is a transport device for transporting a product along a horizontal direction on a work table W. The packaging material supply unit 2 that is provided in parallel and supplies the packaging material S onto the transport mechanism V, and the food material P transported by the turntable transport mechanism T onto the transported packaging material S, are dropped The food supply unit 3 provided at the lower part of the turntable transport mechanism T (see FIGS. 2 and 3), and a turn to prevent inadvertent folding of the both side ears S1 of the packaging material S at a position below the food supply unit 3 And an ear fold prevention device (not shown) disposed below the table transport mechanism.

  Further, as shown in FIG. 1, in order to prevent displacement of the packaging material S conveyed by the conveyance mechanism V, the pair of front and rear conveyance mechanisms V are configured so as to press the upper portion of the packaging material S while moving synchronously with the conveyance mechanism V. An endless belt-shaped holding conveyor 5 for preventing misalignment disposed on one side, a first ear fold 6 for pushing up both side ears S1 projecting on both sides of the packaging material S from below with a folding plate, There is provided a second ear fold portion 7 for folding the food material P into a substantially U shape by pushing the both side ear portions S1 raised by the first ear fold portion 6 from the side with a folding roller 74.

  In addition, the press-down pawls 8 are folded into a substantially U-shape when the presser claws enter from an oblique upper side, and the fold-down presser portions 8 that fold in the both side surfaces of the both-side ears S1 are interlocked. And a fold-up upper portion 9 for pushing up and starting up the packaging material S portion containing the dried laver Q that is unfolded forward and backward.

  Further, as a final folding forming part of the product, for example, three winding rollers are provided, and after being automatically inserted between the respective winding rollers, the respective winding rollers are rotated to each other to wind the food P together with the packaging material S. A part (not shown) is provided, and a product discharge part is provided below the winding part. The entrainment portion also includes a label attaching portion (not shown) for attaching a part of a label L such as POS to one end of the packaging material S in a protruding state. Of course, other known mechanisms can be used for the entrainment portion.

  Next, the specific structure in the foodstuff supply part 3 of the food packaging apparatus 1 is demonstrated.

  The food supply unit 3 provided at the lower part of the turntable transport mechanism T for dropping the food P transported by the turntable transport mechanism T onto the packaging material S to be transported is as shown in FIGS. In addition, a receiving base 31 is coaxially arranged at the lower part of the turntable transfer mechanism T, and the food P is input onto the transfer mechanism V from the rectangular input opening 32 of the turntable transfer mechanism T. A gate 33 formed by a pair of doors with a lower double door opening is provided.

  The gate 33 is integrally connected to a pair of cam receiving plates 34 disposed on one end side of the receiving base 31 and moves up and down together with the closing die 38 via a lifting plate 36 connected to a lifting drive source (not shown). The gate opening / closing cam 35 pushes down the pair of cam receiving plates 34 before bringing the dosing mold 38 into contact with the food material P, so that the gate 33 is opened downward in the form of double doors via the respective hinge portions 33a. . At this time, the gate opening / closing cam 35 restricts the opening of the gate 33 by the cam shape in which the tip is gradually narrowed.

  That is, as shown in FIG. 6, when the pair of cam receiving plates 34 is pushed down via the gate opening / closing cam 35, the food P is temporarily supported at both ends of the gate 33 without dropping the food P, and the gate 33 is fully opened. In this state, the food material P is released and placed on the packaging material S. At the same time, the charging mold 38 comes into contact with the food material P and presses it against the packaging material S.

  In addition, as shown in FIG. 5, when the gate opening / closing cam 35 is raised, the pair of cam receiving plates 34 are arranged in the vicinity so that the pair of cam receiving plates 34 are returned to the closed state and the gate 33 is closed. It is connected with the stopper part 37 by the coil spring arranged upright.

  Next, operation | movement of the foodstuff supply part 3 which concerns on this invention is demonstrated in detail.

  First, as shown in FIG. 6A, the food P is transported to the position of the input opening 32 of the turntable transport mechanism T, and the packaging material S is transported to the position below the gate 33 by the transport mechanism V. At this time, the closing mold 38 and the gate opening / closing cam 35 are lowered.

  6 (b) to 6 (e), the gate opening / closing cam 35 abuts against the pair of cam receiving plates 34 before the dosing die 38 is brought into contact with the food material P, so that the gate 33 is connected to the hinge portion. It is opened downward via 33a, but at this time, the food P is not supported by dropping at the both ends of the gate 33, and at the same time, a gap is formed between the dosing mold 38 and the food P, Until the packaging material S is placed, the food material P is prevented from being crushed.

  Then, as shown in FIG. 6 (f), the food P is released and placed on the packaging material S with the gate 33 fully opened, and at the same time, the input mold 38 comes into contact with the food material P and this is used as the packaging material S. Press on.

  Thus, conventionally, since the food was transported to the input position of the food P by the turntable transport mechanism T and dropped onto the lower packaging material S by natural fall, there was a concern about the possibility of displacement. By providing such a food supply unit 3, natural fall can be prevented, whereby the food P can be reliably arranged on the packaging material S while correcting the positional deviation. At this time, there is no possibility that the food P is crushed.
