Description

  TECHNICAL FIELD The present invention relates to a product guide for a molded sheet punching die, and in particular, a single piece formed by integrally molding a plurality of trays (including those similar to trays for food) and the like in the vertical and horizontal directions. The present invention relates to a product guide used for a “molded sheet punching die” used for punching individual molded trays from a large molded sheet.

  2. Description of the Related Art Conventionally, in supermarkets and the like, trays made of resin sheets such as styrofoam have been used to divide and display foods such as meat and fish by predetermined weights. In these trays, first, as shown in the perspective view of FIG. 3, a predetermined number of tray parts (referred to as trays before punching) 10a are positioned vertically and horizontally like a grid, and they are connected by connecting parts 10b. It is manufactured (molded) in the form of a single large molded sheet 10 connected, and then punched from the molded sheet 10 into individual trays 11, 11... Shown in FIG.

The molded sheet punching die has a “punching unit” equipped with a punching blade adapted to the outer edge shape of the tray, corresponding to the arrangement of the tray part on the molded sheet, like a grid on the holding substrate. It has a configuration in which it is fixed vertically and horizontally.
On the other hand, the arrangement interval (arrangement position) of each tray portion 10a formed on the molded sheet 10 shown in FIG. 3 is not always constant due to variations in the thermal shrinkage rate of the raw material resin, variations in manufacturing conditions, etc. Some dimensional errors occur for each production lot and each part of the molded sheet.
When a dimensional error as described above occurs, if the punching units are fixedly arranged on the holding substrate with a fixed interval, tray punching by the punching blades is not performed in a desired state. As a result, a tray having a desired form as shown in FIG. 4 cannot be obtained. That is, only defective products with different flange widths on each side of each tray can be obtained.

  For this reason, the present applicant arranges each of the punching units on the holding substrate so as to be freely movable (movable) vertically and horizontally by a predetermined dimension, and each punching unit has a tray portion on the molded sheet. Each punching unit is provided on the molded sheet by integrally providing each punching unit with a product guide 101 that conforms to the shape of the tray as shown in FIG. There is provided a molded sheet punching die configured to be positioned so as to exactly match each of the tray portions (see Patent Document 1).

JP 2009-18378.

  However, the product guide is made of wood, hard resin, or the like. In such a case, the product guide is heavy in weight, and therefore the mass of each punching unit including the product guide is increased, and the product guide This prevents the punching unit from freely and quickly moving vertically and horizontally.

In addition, the product guide is manufactured by cutting a material such as wood or hard resin according to the outer shape of the tray by “copying” or the like. It is.
In view of such a situation, as described in Patent Document 1, there is also a “simplified product guide” configured to guide only a member that contacts the outer edge of the tray. In some product guides, positioning may not be performed accurately in a strict sense, and may not be suitable for manufacturing relatively expensive food trays.

  The present invention has been made in view of the above-described problems of the prior art, and an object thereof is to provide a product guide that can be reduced in weight as much as possible and can be provided at low cost.

The product guide according to the present invention has a shape corresponding to the shape of the tray for guiding the punching unit disposed on the holding substrate to be aligned with each tray portion formed on the molded sheet during the cutting process. A product guide having
The product guide is
A bottom plate, a thin plate-like horizontal member that is erected on the bottom plate and arranged in one direction, and is arranged to be erected on the bottom plate and face a direction that makes an angle of intersection with the one direction. A thin plate-like longitudinal member,
By forming a cut so as to correspond to each of the horizontal member and the vertical member, and assembling these horizontal members and the vertical member integrally in the structure of the “partition” using the cut, It is formed on the bottom plate as an integral structure including the bottom plate.

According to the product guide according to the present invention configured as described above, a thin plate material, for example, a foamed resin sheet (or corrugated cardboard sheet) having a predetermined thickness is manufactured according to the dimensions of the product guide drawn by CAD or the like, that is, the product. According to the cross-sectional shape of the part where the guide is to be formed, cutting is performed sequentially using a cutting device such as a cutter or laser cutting device. Of course, when the cutting device is a CAM, the cutting is automatically performed by supplying the drafted (drawn) electronic data to the CAM. Specifically, the cutting is performed by using a cutter or a cutting device for a horizontal member having a cross-sectional shape in which a product guide having a required dimension is cross-sectionally crossed at intervals of 10 mm in a plan view. Cut. In such a lateral member, the cuts are formed at predetermined intervals from the upper end to the lower end or from the lower end to the upper end, for example, at intervals of 10 mm from the upper end to the lower end to a position 5 mm from the upper end. In addition, the vertical member that has the cross-sectional shape of the product guide that is crossed at intervals of 10 mm in a direction having a crossing angle in plan view, for example, in the vertical direction (direction orthogonal to the horizontal direction in plan view) Cut using a cutting device. In such a longitudinal member, the incisions are formed at predetermined intervals from the lower end to the upper end or from the upper end to the lower end, for example, at intervals of 10 mm from the lower end to the upper end to a position of 5 mm from the lower end.
Then, the horizontal member and the vertical member are inserted into the vertical members corresponding to the horizontal members, and both are inserted into a structure (planar) as shown in FIG. Assembling into a structure in which the view is assembled in a matrix. Then, the product guide is completed by arranging and fixing the horizontal member and the vertical member having the structure of “the partition” at predetermined positions on the bottom plate.
And the product guide comprised as mentioned above can be manufactured cheaply and easily compared with cutting materials, such as solid wood, conventionally. In addition, such a product guide can be extremely light in weight (weight reduced to about 1/3 to 1/10).
Therefore, in the case where the punching unit is configured to be movable on the holding substrate, when the punching unit integrally provided with such a product guide is disposed on the holding substrate, the punching unit is The holding substrate can be quickly moved and guided with a small force according to the tray portion of the molded sheet (referred to as a tray before punching).
The product guide according to the present invention can also be used in a configuration in which the punching unit is fixedly arranged on a holding substrate.
Conventionally, when processing a conventional product guide using CAD or CAM, the data required three-dimensional data, but in the case of the product guide according to the present invention, two-dimensional data is required. Therefore, it is possible to create data easily and in a short time. Of course, the cutting can be performed manually, and in such a case, an expensive cutting device is not required.

  In the product guide, when the product guide is configured to guide and move the punching unit movably disposed on the holding substrate by a predetermined dimension, the product guide can be reduced in weight. It is possible to move quickly and with a small force.

  In the product guide, when the thin plate-like horizontal member and the vertical member are made by cutting (cutting) a paper sheet or a foamed resin sheet including a corrugated cardboard sheet having a predetermined thickness, Can be made at low cost. In addition, the material can be easily obtained, and in addition, the product guide can be reduced in weight as much as possible.

  In the product guide, if the crossing angle is a right angle, the structure is preferable.

  In the product guide, at least one of the horizontal member and the vertical member and the bottom plate are fixed to each other, a positioning hole is formed in the bottom plate, and the bottom member of the horizontal member or the vertical member is If the protrusion piece inserted into the positioning hole is formed, the connection with the bottom plate can be easily performed at an accurate position. Moreover, in the said structure, you may comprise so that both may be fixed by apply | coating an adhesive agent at the time of the insertion as needed.

  According to the product guide according to the present invention configured as described above, it is possible to provide a product guide that can be reduced in weight as much as possible and can be manufactured extremely inexpensively and easily. In addition, since the product guide can be made as light as possible, the punching unit can be made as light as possible. If the punching unit is movably disposed on the holding substrate, the punching unit When the tray portion of the corresponding molded sheet is pressed against the product guide, the punching unit can be moved quickly and accurately according to the position of the tray.

It is the perspective view seen from the front a little which shows the structure of the product guide concerning the Example of this invention. It is the perspective view which decomposed | disassembled the product guide shown in FIG. 1, and represented each structure. It is a perspective view which shows the structure of the shaping | molding sheet | seat by which the product part shown in FIG. 1 is used as a part of punching unit, and the tray part is arrange | positioned like the grid of the vertical and horizontal.

(Example)
A product guide according to an embodiment of the present invention will be described as an example with reference to the drawings.

  As shown in FIG. 2, the product guide 1 according to the present embodiment includes a bottom plate 1A having a shape substantially matching the planar shape of the tray 11 (see FIG. 4), and standing on the bottom plate 1A and arranged in the left-right direction. A thin plate-like horizontal member 1B provided, and a thin plate-like vertical member arranged on the bottom plate 1A and arranged in a direction that makes an angle of intersection in the left-right direction (the direction orthogonal to this embodiment: the front-rear direction in this embodiment) 1C. In this embodiment, a polystyrene foam sheet is used as the material for the bottom plate 1A, the horizontal member 1B, and the vertical member 1C. However, the material may be a corrugated cardboard sheet or the like, that is, a cardboard sheet that is lightweight, easy to process, and has a “some degree” durability.

Each configuration of the bottom plate 1A, the horizontal member 1B, and the vertical member 1C is configured to match the dimensions of the required product guide. In other words,
The bottom plate 1A is configured to have a dimension that is substantially equal (exactly very small) to the dimension of the opening end (upper end in FIG. 4) 11a of the inner peripheral surface of the tray 11 shown in FIG.
Further, the horizontal member 1B is equal to the cross-sectional shape of each portion of the shape of the tray 11 shown in FIG. (Very small).
Further, the vertical member 1C is equal to the cross-sectional shape of each part obtained by crossing the shape of the tray 11 shown in FIG. 4 (in this embodiment, the internal space) S at intervals of 10 mm in the vertical direction (accurately). (Very small). As another embodiment, an external shape (external space) may be used instead of the internal space S of the tray 11.

  By the way, in this embodiment, as described above, the internal space S has a transverse section or a longitudinal section at intervals of 10 mm. However, the internal space S may have a transverse section or a longitudinal section at equal intervals according to other numerical values, or may be uneven. A transverse section or a longitudinal section may be provided at intervals. Specifically, as the product guide 1, it is desirable to reduce the interval at a portion where the shape changes, and increase the interval at a portion where the shape does not change.

  Then, incisions 2 (see FIG. 2) for forming “assembly partitions” are provided at positions (parts) corresponding to the horizontal member 1B and the vertical member 1C, respectively. Specifically, as shown in FIG. 2, the horizontal member 1B is provided with cuts 2A at intervals of 10 mm from the center in the left-right direction, for example, and the vertical member 1C is provided from the center in the front-rear direction. Cuts 2B are provided at intervals of 10 mm on both sides. The cut 2A of the horizontal member 1B is a cut having a depth of ½ of the maximum height from the lower end upward, for example, a cut of 15 mm in this embodiment, and the cut 2B of the vertical member 1C. Is an incision having a depth of ½ of the maximum height from the upper end downward, for example, an incision having a depth of 15 mm in this embodiment.

Further, as shown in FIG. 2, protrusions 1 c having a rectangular shape in a bottom view are formed at both ends of each bottom surface of the vertical member 1 </ b> C so as to face downward.
On the other hand, the bottom plate 1A is formed with a positioning hole 1a into which the protruding piece 1c is inserted at a position corresponding to the protruding piece 1c of the vertical member 1C.

And this product guide 1 is comprised by assembling the said bottom plate 1A comprised as mentioned above, the horizontal member 1B, and the vertical member 1C as follows. That means
In the case of this embodiment, as shown in FIG. 2, first, the vertical member 1C is positioned on the bottom plate 1A, the longest one in the front and rear is positioned at the center position, and the protruding piece 1c is positioned in the positioning hole of the bottom plate 1A. 1a is inserted and set in the same manner, the next long vertical member 1C is set in the same manner on both sides thereof, and the next long vertical member 1C is set in the same manner on both sides thereof. The vertical member 1C is set.
Next, the longest longitudinal member 1B is positioned at the center position, and the cut 2A is inserted into the cut 2B of the vertical member 1C perpendicular to the horizontal member 1B. The next long horizontal member 1B is set on both sides in the same manner as described above, and the next long horizontal member 1B is set on both sides in the same manner as described above. Set 1B.

  As a result, as shown in FIG. 1, the horizontal member 1 </ b> B and the vertical member 1 </ b> C are placed on the bottom plate 1 </ b> A in a “partition” state. In the product guide 1 assembled in this way, the outer edges of the horizontal member 1B and the vertical member 1C are exactly aligned with the corresponding portions of the inner peripheral surface of the tray (see FIG. 4), which is a product. The dimensions are such that they abut. In other words, the tray is constrained by the product guide 1 so that the product guide 1 does not idle when the product guide 1 is covered with the tray or in a reverse state.

  And the product guide 1 comprised as mentioned above is used similarly to the conventional product guide. That is, the product guide 1 is integrally disposed as a guide member in a punching unit in which punching blades are attached to the periphery (not shown), and has a grid pattern vertically and horizontally in the molded sheet 10 shown in FIG. The punching units are arranged so as to be movable (movable) vertically and horizontally by a predetermined size on a holding substrate (not shown) of a molded sheet punching die (not shown).

  As described above, in a state where the punching unit having the product guide 1 mounted thereon is arranged on the holding substrate, the molded sheet 10 shown in FIG. 3 is turned upside down from FIG. 3 from above. , The product guide 1 guides each punching unit so that it fits exactly with each tray portion of the molded sheet 10, and position adjustment automatically occurs in the front-rear and left-right directions on the holding substrate.

  In this guide, the product guide 1 is much lighter than a conventional wooden product guide, and thus can be moved quickly and easily with a very small force. For this reason, for example, even when the engagement force (force to be moved) with the product guide is weak, such as a tray with a shallow recess, it is possible to guide accurately and quickly.

  The product guide 1 can be easily manufactured by using a cutting device such as a cutter or a laser cutting device using a resin sheet, cardboard or the like as a material. Moreover, if the horizontal member 1B, the vertical member 1C, and the bottom plate 1A are drawn by CAD, it can be manufactured easily and in a short time using a CAM type laser cutting device.

  In the above description, the components other than the product guide 1 are not shown and the configuration thereof is not described in detail. However, the configuration and the operation that are not described are substantially the same as the conventional ones. The description is omitted.

  In the above embodiment, the example in which the punching unit is arranged movably in the vertical and horizontal directions on the holding substrate has been described. Of course, the present invention can also be used when the punching unit is fixedly arranged on the holding substrate. It goes without saying that the product guide according to the invention can be used and basically the same effect can be obtained except for the action in movement.

  Further, the present invention is not limited to the above-described embodiments, and it goes without saying that the present invention can be implemented in various forms within the scope based on the technical idea of the present invention.

  The product guide concerning this invention can be utilized in the manufacture field | area of the tray as a food packaging material used for sale of foodstuffs.
