RU29683U1 - FOLDER AND GLONING SEMI-AUTOMATIC "IMPULSE" - Google Patents

Description

The utility model relates to equipment for the manufacture of boxes from corrugated cardboard, in particular, for gluing boxes on the connecting clan.

There are known automatic machines for this purpose, for example, Emba folding and gluing machines (Sweden), or AFSK machines of domestic production for folding and gluing boxes (B.V. Kononov, G.E. Landau, E.M. Pogrebov "Corrugated cardboard. Forest industry, M., 1971, S. 117-118, 136-138). The machines include: a piece feed section (feeder), a folding section, a gluing section, a conveyor outlet. All operations on such equipment are mechanized. Machine tools have high productivity. However, their use is advisable only in large enterprises with large volumes of output, in the manufacture of large batches of boxes of a certain size.

Pediatric equipment are:

1) such automatic machines are effective only for large runs of manufactured sizes of boxes, as their conversion to a new format takes quite a long time. In the production of a large assortment of boxes in small batches, when frequent changes are required, their use is not economically feasible;

2) the large overall dimensions of the machine due to the length of the folding section and, as a result, the inability to use such equipment in small production areas.

Also known is a folding-gluing semiautomatic device (box sealing machine) R2880 from Piemonte Meccanica SPA (Italy), which is a prototype of a utility model. There is no folding section in the machine, and the bending operation is performed manually by the operator (excerpts from the machine passport are attached). The machine is designed for the production of boxes in small batches. It contains a table for manual folding of blanks, a glue application device, the output conveyor. The table has a lifting mechanism, ensuring the maintenance of a constant level of the top sheet in the bale. The operator manually puts a pile of blanks on the table, takes the top sheet individually and folds it, and folding is not done completely to provide the necessary space for passing through the glue application area, and then feeds the blank to the guides of the glue-bearing assembly. Further, when the workpiece passes through the clamping device, it is finally folded and the box wall is clamped to the connecting valve. The box enters the output conveyor, transferring it to the accumulation zone. The disadvantages of the design are:

1) The need to equip the machine with a separate drive

table lifting mechanism supporting the top bale sheet at the same level, which increases energy consumption;

2) The complexity and bulkiness of the design and, accordingly, the large expenditures of time and material resources for maintenance;

3) The probability of skewing the boxes during gluing due to uneven folding of the workpieces, leading to a large number of scraps or complicating the design of the machine by installing an additional mechanism for aligning the boxes.

The purpose of the development of the utility model is simplicity and ease of maintenance, the possibility of using it in factories with frequent changes in the standard sizes of boxes, compactness, and reduction of energy consumption.

This goal is achieved in that the number of machine nodes is reduced due to the combination of their functions.

Figure 1 shows a schematic diagram of a folding gluing semiautomatic device "Impulse. The main working body of the semiautomatic device is shaft 1, on the trunnion of which an applicator roller with a diameter close to or equal to the shaft diameter is installed. The roller, rotating together with the shaft, applies glue to the connecting valve. It is possible to use other gluing systems, for example, based on the supply of glue with drops, or trickles, or in another way using appropriate devices. To ensure the capture of the cardboard blanks by the shaft and its maintenance

without slipping, the shaft has a friction surface, which is achieved either due to the roughness of all or part of its surface, or by rubberizing the entire shaft or its part, or by using another coating on the entire surface of the shaft or its part, providing sufficient adhesion.

To the upper part of the shaft on one side there is a feeder (workpiece feeding table) 2, and to the lower part of the shaft on the other side there is a folding table 3.

The folding table simultaneously serves as a clamp for final gluing of the drawer and is made in the form of a plate having a certain degree of mobility to provide the gap necessary for passing the drawer with the shaft 1 and providing a pressing force due to the weight of the plate itself or due to the action of elastic forces created, for example, spring or in any other way.

A pile of blanks is placed in a feeder 2 between the plate 4 and the shutter (gate) 5, set in such a way that the gap between the gate 5 and the shaft 1 allows only one workpiece to pass between them. The lower workpiece is captured by the rotating shaft 1 and pulled by it into the folding zone. In this case, the lower side of the valve of the workpiece touches the roller and glue is applied. The workpiece lands on folding table 3, where the operator manually

4 folds it along the groove lines (folds), while aligning

in order to avoid the occurrence of strife, and feeds a folded box under the same shaft 1, which captures the box and transfers it to the storage node. When passing the box between the shaft 1 and the table 3, the glue line is clamped.

Thus, the same Bajf performs several functions simultaneously: feeding the workpiece, applying glue, pressing the folded box and transporting it to the finished product storage. The table also has a multifunctional purpose, at the same time being a platform for the operator to perform folding the drawer, as well as providing an adhesive joint clamp and final gluing together with the shaft.

Such a combination of functions ensures the compactness of the machine, the convenience of the operator, the simplicity and reliability of the design, reduced energy consumption, easy and quick changeover when switching to the manufacture of boxes of a different size.
