Description

  The present invention relates to an automatic product stacking apparatus that stacks cup-shaped products supplied from a manufacturing process and other various products in an appropriate number of rows for automatic boxing.

  As an apparatus for accumulating products in an appropriate number of rows for automatic boxing, apparatuses using an air injection nozzle have been conventionally provided (Japanese Patent No. 2660648, Japanese Patent No. 3964971, Japanese Patent No. 4122385, etc.).

That is, the product sent in a line from the manufacturing process is supplied onto a wide conveyor, and air is alternately sprayed from both sides of the product supplied on the wide conveyor, or the air injection is stopped. This is a device that accumulates products by allocating products to an appropriate number of columns.
Japanese Patent No. 2660648 Japanese Patent No. 3964971 Japanese Patent No. 4122358 The apparatus using the air injection nozzle has a limitation in speeding up the integration because products are individually distributed in an appropriate number of rows. Moreover, the generation of air injection noise from the air injection nozzle has an effect on the work environment.

  SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide an automatic product stacking apparatus that can increase the speed of stacking and transporting products and that does not generate noise.

  In order to achieve the above-mentioned object, the product automatic stacking apparatus of the present invention can traverse from both sides to the front end position of the product supply path in front of the product supply path provided from the manufacturing process. A plurality of product sorting conveyors having a length to be placed and having product stoppers arranged at the front end portion and the rear end portion are provided, and a multi-row transport conveyor is provided in front of the product sorting conveyor. (Claim 1).

  In general, products are supplied in a line from the manufacturing process. According to the present invention, the products supplied in a row from the manufacturing process can be quickly accumulated in an appropriate number of rows on a multi-row transport conveyor provided for automatic boxing.

  According to the present invention, first, a first product sorting conveyor (hereinafter referred to as “first sorting conveyor”) is positioned at the front end position of the product transport path provided from the manufacturing process, and is further driven. The product is supplied from the manufacturing process onto the first sorting conveyor.

  Subsequently, when it is confirmed that a predetermined number of products have been placed on the first sorting conveyor, the first sorting conveyor is temporarily stopped to drive the row required for automatic boxing (the number of products decreases). The product placed in a row is driven to the transverse stop and sent to a succeeding multi-row transport conveyor provided for boxing.

  At the same time, the traversing of the first sorting conveyor is confirmed, and a second merchandise sorting conveyor (hereinafter referred to as “second sorting conveyor”) is traversed to the front end position of the merchandise conveying path provided from the manufacturing process. The product is further driven, and the product is supplied from the manufacturing process onto the second sorting conveyor.

  Subsequently, when it is confirmed that a predetermined number of products have been placed on the second sorting conveyor, the second sorting conveyor is temporarily stopped to drive the row necessary for automatic boxing (the number of products decreases). The product placed in a row is driven to the transverse stop and sent to a succeeding multi-row transport conveyor provided for boxing.

  At the same time, the traversing of the second sorting conveyor is confirmed, the first sorting conveyor is traversed and returned to the front end position of the product supply path provided from the manufacturing process, and the above process is repeated.

  The supply of a predetermined number of products onto the first and second sorting conveyors and the supply of products to the subsequent multi-row transport conveyor are performed by a product stopper or the like disposed at the rear end and front end of each sorting conveyor.

  Further, the drive and drive stop control of the first and second sorting conveyors are performed after confirming that a predetermined number of products have been placed on each sorting conveyor. The predetermined number of products can be confirmed by various product counters.

  In addition, the transverse control of the first and second distribution conveyors is a reduction state of the products in each row on the multi-row transport conveyor for boxing of products continuously provided on the first and second distribution conveyors. Confirmed is done. Each control is automatically performed by predetermined computer control (microcomputer control).

  According to the product automatic stacking apparatus of the present invention, it is possible to speed up the collection of boxed products and to obtain an effect that does not affect the work environment, such as generation of noise.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention, and is a schematic plan view of an automatic product stacking apparatus of the present invention. FIG. 2 is a schematic side view of FIG. 1, and FIG. is there.

  In the figure, 1 is a product supply path provided from a manufacturing process (not shown). In the present invention, the product supply path 1 is traversable from both sides at the front end position of the product supply path 1 and is a length for placing a predetermined number of products G A plurality of product sorting conveyors having a height are provided. That is, the 1st distribution conveyor 2 and the 2nd distribution conveyor 3 are provided.

  In FIG. 1, the first distribution conveyor 2 and the second distribution conveyor 3 are both shown in a position superimposed on the front end position of the product supply path 1 provided from the manufacturing process. The first distribution conveyor 2 and the second distribution conveyor 3 are formed so as to traverse both sides of the product supply path 1 provided from the manufacturing process.

  In the present invention, the first sorting conveyor 2, the pulley 4 that stretches the first sorting conveyor 2, and the conveyor drive motor 5 are supported on a support plate 6 and unitized. This configuration is exactly the same for the second sorting conveyor 3. And the both ends of each said support plate 6 are each engaged with the rails 7 and 7, and it is comprised so that traversal is possible.

  An example of the implementation of the transverse configuration of the first distribution conveyor and the second distribution conveyor 3 will be described below.

  In the embodiment of FIG. 1, the transverse configuration of the first distribution conveyor 2 and the second distribution conveyor 3 is performed by servo motors 8 and 9 and timing belts 10, 10 and 11, 11.

  That is, in the embodiment of FIG. 1, the first distribution conveyor 2 is performed by connecting the timing belts 10 and 10 driven by the servo motor 8 to the support plate 6 portion that supports the first distribution conveyor 2. Further, timing belts 11 and 11 driven by a servo motor 9 are connected to the substrate 6 portion supporting the second sorting conveyor 3. That is, each of the first distribution conveyor 2 and the second distribution conveyor 3 has a transverse width S.

  Furthermore, a multi-row transport conveyor 12 is provided in front of the first distribution conveyor 2 and the second distribution conveyor 3. In the embodiment shown in the drawing, the multi-row transport conveyor 12 is configured to stack the products G in five rows. However, in the present invention, the number of integrated columns is not limited to five.

  In the figure, 13 is a product stopper disposed at the front end position of the first and second distribution conveyors 2 and 3, and 14 is disposed at the rear end position of the first and second distribution conveyors 2 and 3.
