Description

The invention relates to teaching aids, and in particular, to a method for manufacturing a visual teaching aid that can be used for teaching literacy and numeracy of children of preschool and primary school age.

Known visual aids, the manufacture of which uses the following operations: form a store for chips in the form of a rectangular box, divided into cells; form a demonstration panel that performs the function of a lid for the specified box; magnetic strips, or strips with Velcro engagement elements, or strips of adhesive plastic, are fixed on the inside of the panel; digital or alphabetic characters are applied on the front side of the chips, and fastening elements on the back side that fix the chips on the panel strips (see WO 02065430). The production of the manual is complicated due to the need to form a box divided into cells, and also because of the need to use special fastening elements for fixing the chips on the panel, placed both on the panel and on the chips.

A textbook is known for a similar purpose, formed from a long tape rolled up into a roll, along the length of which strips are attached in parallel rows, attached with their lower edges to the tape. Additionally, each strip is attached to the tape with vertical seams that define the lateral borders of the pockets into which letter carriers are inserted (see US 4636172). A roll-up tape with pockets for carriers of alphabetic characters is inconvenient for storage and use and short-lived. The strips fastened with tape forming pockets require strict orientation in the process of their attachment, which complicates the technology of manufacturing the manual. In addition, the strips tend to disconnect them from the surface of the tape during operation of the manual.

The closest analogue to the claimed invention is a method of manufacturing a training aid, implemented in the technical solution according to patent RU 27875 U1. The method includes forming a folder with pockets for storing cards with alphabetic and / or digital symbols (training symbols, symbols used in the learning process) by making rectangular outer and inner blanks from polyvinyl chloride film, manufacturing strips of measured length, securing strips on the inner film with the formation of cells for cards with alphanumeric characters, placement between the blanks from the film of a cardboard insert and fastening blanks around the perimeter. As a disadvantage of the known method, it is necessary to point out the problems that arise due to technological features of the formation of pockets for cards. The process of obtaining pockets is time-consuming, because It requires the use of operations for cutting the strips from which the pockets are formed, aligning the position of the strips on the substrate before fastening them, followed by maintaining the required position, fastening each strip with the substrate. The possibility of displacement of the strips previously laid on the substrate, but not yet fixed, can lead to their non-parallelism, which will be fixed during bonding, as a result of which the required quality of the finished product will not be ensured.

The proposed technical solution is aimed at eliminating these shortcomings.

The technical result achieved by using the present invention is to simplify the manufacturing technology of visual teaching aids and to improve its quality and operational reliability.

To achieve the specified technical result, a method for manufacturing a training manual is proposed, which includes forming a folder with pockets for cards with training symbols by pre-manufacturing rectangular blanks for the cover and lining, as well as blanks for pockets, followed by connecting all the blanks into a single folder. The pocket blank is formed from a plate in which parallel slots are cut out on a punching machine, passing along the length or width of the plate, while ensuring the distance between each adjacent pair of parallel slots, sufficient for the subsequent formation of pockets for cards with learning symbols. The resulting pocket blank is duplicated with the liner blank, placing the latter under the pocket blank, and the specified blanks are fastened along their perimeter, as well as along the lines defining the lower borders of the card pockets, and along the lines passing between the slots of the pocket blank and defining the side borders pockets. The blank of the pockets and the blank of the lining are fastened after duplication with the blank of the cover around the perimeter of these blanks.

At least one cardboard insert is preliminarily placed between the pocket blanks and the liner blanks after being duplicated with the blank blanks between them.

Blanks for the cover, lining and pockets are made of a polyvinyl chloride-based polymer film.

The fastening of the pocket blank with the blank blank during duplication, as well as their bonding after duplication with the blank blank is carried out by high-frequency currents.

In addition to forming folders, a demo insert with pockets is formed to compose syllables, words and perform arithmetic operations.

The invention is illustrated by drawings, where:

figure 1 shows the proposed training aid in the form of a double-leaf folder in the folded state;

figure 2 - study guide in the open state;

figure 3 is a demonstration insert with pockets for compiling syllables, words and performing arithmetic operations.

A method of manufacturing a training manual provides for the following technological operations.

Cutting material

On a punching machine, using a stamp, cardboard is cut from sheets into rectangular cardboard inserts.

On a unwinding machine, a roll for blanks of pockets, a roll for blanks of linings and a roll for blanks of covers are made from a roll of a polymer film based on polyvinyl chloride.

On a cutting machine, the film rollers are cut with knives into blanks for pockets, for lining, for cover.

On a punching machine, the pockets themselves are cut with a stamp in one go (in one operation).

Welding

On the HDTV installation, using the electrode, the lining blank and the pocket blank are welded, ensuring their duplication.

In addition, at the final stage of manufacturing a folder on a high-frequency installation, an electrode is used to weld a blank for the folder cover and duplicated blanks for the lining and blanks for pockets by inserting cardboard blanks between them.

Embossing

Using the embossing apparatus (embossing press) and cliche, the foil is inscribed on the finished folder by hot stamping.

Making a demo liner

On the unwinding machine, using the knives from the roll of PVC film, film rollers are made.

On a high-frequency installation for welding PVC film using an electrode, welding pockets, linings and liner covers are welded.

The following is a more detailed description of the individual operations with reference to the drawings.

The blank of the pockets is formed from a rectangular plate 1, in which parallel slots 2 are cut out, passing (oriented) along the length of the plate 1. When making slots 2, provide a distance between each adjacent pair of parallel slots 2 that is sufficient for the subsequent formation of pockets 3 for cards with educational (alphabetic and / or digital) characters. Slots can be made both at the same and at different distances between them. It is possible to form slots 2 and the width of the plate 1, as a result of which in the finished product the slots will be oriented not perpendicular to the fold of the cover, but parallel to it, which is also a possible option for the implementation of the training manual. To ensure high productivity in the formation of pockets and to obtain a high-quality workpiece with a strictly ordered arrangement of pockets, the cutting of all slots 2 is carried out on a punching machine simultaneously in one operation (at one time).

The resulting blank of pockets is duplicated with the blank of the lining, which is placed under the blank of the pockets. Fasten the workpiece pockets and workpiece lining along line 4, passing along their perimeter. Line 4 in the area perpendicular to the slots 2 can extend both outside the boundaries of the slots 2 (see position 4a) and intersecting the end sections of the slots 2 (see position 4b), and in the second case (pos. 4b) a more reliable fixing of extreme pockets and more convenient use of them.

In addition, a bond is made along lines 5 that define the lower boundaries of the pockets 3 for individual cards; bonding is carried out by high-frequency currents simultaneously along all lines 5. Lines 5 run parallel to the slots 2 cut in the pocket blank.

And, in addition, the fastening of the pocket blank and the lining blank is carried out along the lines 6, which extend in the sections between the slots 2 perpendicular to the last and extend from the corresponding line 5 (the lower border of the pockets) to the nearest edge of the nearest slot 2 and intersect the indicated edge of the slot 2, thereby ensuring reliable fixation of the side walls of the pockets along the entire height of the walls and preventing possible tearing of the pocket along the side walls. Lines 6 define the lateral borders of pockets 3 for individual cards. Bonding in these sections is carried out by high-frequency currents simultaneously along all lines 6. For the best quality manufacturing, it is preferable to bond with high-frequency currents simultaneously in all sections, i.e. along line 4, passing along the perimeter of the pocket blank and the lining blank, along lines 5 defining the lower borders of the pockets 3, and along lines 6 defining the side borders of the pockets 3.

The blank of the pockets and the blank of the lining after their duplication are fastened to the blank of the cover around the perimeter of these blanks (line 7). Before bonding, a cardboard insert is placed between the duplicated blanks and the blank blank.

Assembling a tutorial

On the assembly site produce assembly manuals as follows.

In the finished folder 8 put a demo insert 9, a set of cards with training symbols. Folder 8 is packed in a plastic bag and a label is pasted.
