Description

Mineral water bale laminate system using slip sheet

Technical Field

The present invention relates to a stacking system which efficiently performs stacking work for objects to be loaded such as mineral water packages when a slide board is used to improve the utilization of the loading space of a container.

Background

In general, so-called beverage products such as mineral water and various beverages are packaged in so-called bottles and distributed and sold, and particularly, mineral water products are mainly configured in the form of mineral water buckets filled with PET materials.

Further, in the case of mineral water products configured in such a bottled form, the distribution cost is a considerable amount of the original price of the products, and in order to improve the distribution efficiency in a production factory, a plurality of products are combined together to form a single package, and then the package is loaded in a container or the like and shipped.

Mineral water products configured in a bale form (hereinafter referred to as mineral water bales) have a considerable volume and weight, and therefore, in order to transport and load the mineral water products into containers, a forklift is generally used.

In general, when carrying goods by fork lift truck, the goods are not lifted directly onto the loading arms of the fork lift truck, but rather are lifted onto a tray (pallet), which is then inserted into the tray and lifted, and the tray is used as an aid in the handling of mineral water bales.

On the other hand, the mineral water bales are designed to have optimal weight and volume in consideration of the specification and loading efficiency of each mineral water barrel, and three or four segments form one mineral water bale in case of a 2-liter mineral water barrel.

Further, in the case of transporting a package of mineral water by a forklift in a conventional manner prior to using a slide pallet described later, only one package of mineral water is placed on a tray and transported, and as a result, one tray needs to be combined when transporting one package of mineral water, and the tray has to be loaded into a container together with the package of mineral water.

In addition, in consideration of the specification (vertical height) of the container, the container for ships, which is generally used, can only accommodate three mineral water buckets in two layers because two trays are also accommodated in addition to the mineral water package as described above, and thus the space for accommodating the container is unnecessarily consumed.

Therefore, the conventional technique of loading the tray into the container together with the packed mineral water has a problem of greatly hindering the improvement of the productivity of beverage products such as mineral water, which is a considerable part of the product cost due to physical distribution.

In order to solve such a problem, a technique of a forklift using a combination of a slipsheet (slip sheet) and a so-called push-pull method for optimizing the slipsheet has been proposed.

The sliding plate is a thin plate for reducing surface friction, and is arranged between the upper side and the lower side of the weight products when the weight products are stacked up and down, so that the weight products on the upper side can easily slide out.

The push-pull type forklift uses a push-pull device to pull an article onto a loading arm or push an article off the loading arm without using a pallet.

When such a slide plate is used, the weight product on the upper side is stacked on the weight product on the lower side in a push-in manner in a state where the slide plate is placed on the weight product on the lower side, whereby the number of trays to be used can be reduced.

However, according to the conventional technology, although the stacking work for optimizing the skid plates can be performed by the push-pull forklift, the push-pull forklift is operated by the operation of the operator like a general forklift, and therefore, there are problems in that a large number of repeated works are required to stack a large number of heavy products, the amount of works varies depending on the skill of the operator, and an accident may occur during the work.

The first lifting device 10 and the second lifting device 20 have the same structure, and press a side surface of the spring water bale W to be lifted, and may include, as an example: four pressing plates 12 configured in the form of four side surfaces surrounding the bale of mineral water; a driving device (not shown) for driving the pressing plate 12; and an elevating member (not shown) for elevating the pressing plate 12. (refer to FIG. 3)

Each of the lifting devices is operated in a state in which the pressing plates 12 are lowered to surround four side surfaces of the mineral water package W after the mineral water package W arrives, and then the pressing plates 12 are moved in opposite directions to press the four side surfaces of the mineral water package W, and the pressing plates 12 are lifted to lift the mineral water package W. (refer to FIG. 3)

The pallet supply unit includes a first pallet supply device 30 and a second pallet supply device 40, and each of the

pallet supply devices

30 and 40 may be configured to be capable of sucking an object to be processed so that the object to be processed having a thin thickness and a large area can be stably conveyed.

The mineral water bale laminate system according to the present invention may further comprise: an intermediate material supply unit (refer to fig. 1) disposed between the first and second

pallet supply units

30 and 40, supplying an intermediate material before supplying the intermediate slipsheet S2 and placing it on the lower spring water bale W2.

The intermediate material is used to prevent the packaging film from being torn or the like by the loading arm of the forklift directly contacting the upper surface of the lower mineral water package W2 in the process of the loading arm of the forklift entering under the intermediate slide plate S2 when the upper mineral water package W1 is lifted by the forklift in a state where the upper mineral water package W1 and the lower mineral water package W2 are stacked after the product is unloaded.

According to the laminated spring water package system according to the present invention, as shown in fig. 4a to 4j, the upper spring water package W1 is transferred first by the transfer line and lifted by the first lifting device 10, and then the bottom slide plate S1 and the middle slide plate S2 are supplied to the upper surface of the second tray P2 and the upper surface of the lower spring water package W2 supporting the lower spring water package W2 by the pallet supply unit in a state where the transferred lower spring water package W2 is lifted by the second lifting device 20, and the upper spring water package W1 lifted by the first lifting device 10 is placed on the middle slide plate supplied to the upper surface of the lower spring water package W2.

The operation method of the mineral water bale stacking system will be described in more detail below with reference to the operation method of each step.

Before the description is given: in the laminated system for packaging mineral water of the present invention, the mineral water packages stored in the automatic warehouse are sequentially discharged from the warehouse and conveyed along the conveying line, and a pair of consecutive mineral water packages are combined and stacked up and down, so that the mineral water package that arrives first becomes the upper mineral water package W1, and the mineral water package that arrives next becomes the lower mineral water package W2.

The operation method of the mineral water packing and laminating system according to the present invention is configured to sequentially perform the following steps: i) a first lifting step; ii) a second lifting step; iii) a tray advancing step; iv) a bottom slipsheet supply step; v) a tray resetting step; vi) placing the mineral water bales at the lower side; vii) a middle slip sheet supply step; viii) upper mineral water bale stacking step, and the operation of each step will be described below.

i) In the first lifting step, the first time of lifting,

the upper spring water bale W1 conveyed first along the conveying line passes directly through the second lifting device 20 to reach the first lifting device 10 (see fig. 4a), and is lifted and kept lifted by the first lifting device 10, so that the first tray P1 on which the upper spring water bale W1 is originally placed is discharged and conveyed to the tray storage device. (refer to FIG. 4b)

ii) in a second lifting step,

after the upper spring water bale W1, the lower spring water bale W2 is transferred in a state of being placed on the second tray P2 (see fig. 4c), and is lifted by the second lifting device 20 to be separated from the second tray P2 which is originally placed. (refer to FIG. 4d)

iii) in the tray advancing step,

in a state where the lower spring water bale W2 is lifted by the second lifting device 20, the second tray P2, which originally received the lower spring water bale W2, is continuously conveyed along the conveying line for a certain distance, thereby being separated from the second lifting device 20. (refer to FIG. 4d)

iv) in the bottom slipsheet supplying step,

the bottom slipsheet S1 supplied by the first secondary sheet supply means 30 is placed on the second tray P2 separated from the second lifting means 20. (refer to FIG. 4e)

v) in the tray-returning step,

the second tray P2 is reset to the second lifting device 20 in a state that the bottom slip sheet S1 is placed on the second tray P2.

vi) in the lower spring water bale packing step,

in a state where the second tray P2 is returned to the second lifting device 20, the lower spring water bale W2 descends and is seated on the bottom slide plate S1. (refer to FIG. 4g)

vii) in the intermediate slide plate supplying step,

the intermediate slip sheet S2 supplied by the second secondary sheet supply means is placed on the lower spring water bale W2 conveyed from the second lifting means 20. (refer to FIG. 4h)

viii) upper mineral water bale stacking step,

the lower spring water bale W2 is conveyed to a first lifting device 10 (see fig. 4i), and the upper spring water bale W1 lifted by the first lifting device 10 is lowered and stacked on the lower spring water bale W2 via the intermediate slide plate S2. (refer to FIG. 4j)

In this manner, according to the operation of the laminated mineral water package system according to the present invention, the lower mineral water package W2 and the upper mineral water package W1 are vertically laminated, the bottom slide plate S1 is interposed between the second tray P2 and the lower mineral water package W2, and the middle slide plate S2 is interposed between the lower mineral water package W2 and the upper mineral water package W1.

Then, the lower spring water package W2 and the upper spring water package W1 are stacked in this manner, conveyed along a conveying line to a delivery yard, and then conveyed by the push-pull type forklift as described above and loaded into a container.

At this time, the push-pull forklift loads the upper and lower mineral water bales W1 and W2 by inserting and lifting the loading arm into the second tray P2, and pushes the upper and lower mineral water bales W1 and W2 into the container by the push-pull device when the mineral water bales are loaded into the container.

Therefore, the container is loaded with only the mineral water bales W1 and W2 on the upper and lower sides of the knock-out tray and the intermediate slide plate S2 interposed therebetween, and thus the container is not loaded with food on the tray as in the conventional case.

On the other hand, when the present invention includes the intermediate material supply means, in the operation method thereof, the intermediate material supply step is performed before the vii) intermediate slide plate supply step, whereby the intermediate material is first placed on the lower mineral water bale W2, and then the intermediate slide plate S2 is placed thereon.

In addition, when the intermediate material is used as described above, in a state where the upper mineral water package W1 is lifted by the forklift in a state where the upper mineral water packages W1 and the lower mineral water package W2 are stacked after the upper mineral water packages W1 and W2 loaded in the container are unloaded, the loading arm of the forklift enters between the intermediate slide plate S2 and the intermediate material, and thus, the phenomenon that the packaging film is torn due to the loading arm directly contacting the upper surface of the lower mineral water package W2 is avoided.
