Description

BACKGROUND OF THE INVENTION Field of the Invention [0001]

The present invention relates to a bottled water package stacking apparatus capable of effectively lifting and stacking heavy products such as bottled water packages.

So-called beverage products, such as bottled water and various beverages, are generally packaged in a so-called bottled manner and distributed and sold. In the case of bottled water, bottled water is mainly contained in PET bottles.

In order to increase the efficiency of the logistics in the production plant, a plurality of products are bundled into a single package form, and then the bottles are packed into containers They will be loaded and shipped.

Since bottled water products (hereinafter referred to as "bottled water packages") having a package form have a considerable volume and weight, they usually use forklifts to transport them to containers.

Here, in the case of transporting an article using a forklift, a method of raising the article by placing the article on the pallet without raising the article directly on the loading arm of the forklift and lifting the loading arm by the pallet is common. It is used as a means.

Meanwhile, the bottled water package is set to have the optimum weight and volume considering the specifications of the respective water bottles and the loading efficiency. For example, in the case of the water bottles of 2 liters, the bottled water package is composed of three or four stages to form one bottled water package .

When transporting the bottled water package using the forklift in the conventional manner before using the slip sheet as described below, only one bottled water package needs to be carried and carried on the pallet. As a result, when one bottled water package is transported, The pallet must be combined, and inevitably the pallet should also be loaded into the container with the bottled water package.

Considering the standard of the container (up-and-down height), only two layers of three-stage bottled water packages can be stacked for commonly used marine containers. This is because, in addition to the bottled water package, two pallets This is because the loading space of the container is undesirably eroded.

Therefore, according to the prior art in which the pallet is loaded on the container together with the bottled water package, there is a problem that the productivity of beverage products such as bottled water, whose distribution efficiency accounts for a large portion of the cost of the product,

In order to solve such a problem, a technique of using a special so-called push-pull type forklift using a slip sheet and a slip sheet has been proposed.

The slip sheet is a thin plate member configured to reduce the friction of the surface, so that when the weight product is stacked up and down, it is interposed between the upper and lower weight products so that the upper weight product can easily slip out.

The push-pull type forklift can pull the article by using a push-pull device without using a pallet and lift it on the loading arm, or push down the article on the loading arm.

When the slip sheet is used, the weight of the pallet can be reduced by stacking the upper weight product on the lower weight product while the slip sheet is placed on the lower weight product.

However, according to the conventional art, although the stacking operation specialized for the slip sheet can be performed by using the push-pull forklift, the push-pull forklift is also operated by the operation of the operator like a general forklift. There is a problem that not only the repetitive work is required but also the work amount is changed according to the skill level of the worker and the risk of accident is caused in the work process.

2, the pressing and holding module 20 includes a lifting frame 22 guided by the post frame 10 and a lifting frame 22 supported by the lifting frame 22 and centered on the bottled water package P (Four) pressing plates 231, 232, 233, and 234 arranged to face each other and moving in the horizontal opposing direction and the pressing plates 231, 232, 233, and 234 And positioning means for adjusting the position of the bottled water package so that the bottled water package (P) reaches the correct working position before being pressed and grasped.

The movable unit is attached to each of the pressing plates 231, 232, 233 and 234 as shown in Figs. 3, 4, 5 and 6, and the rack gear portion 251 is attached to one side A connecting gear 26 meshing with each jack bar 25 and a movable motor 27 for moving the connecting gear 26. The jack- , And a movable gear 271 is provided on the rotating shaft of the movable motor 27.

The movable means is a type of mechanical device called a so-called rack-jack which is a combination of a jack bar 25 and a connecting gear 26 so that the rotational driving force of the movable motor 27 is transmitted to the jacket 25 via the movable gear 271, The linear motion force of the motor 25 is transferred and transmitted. Since the configuration is a well-known technology, a detailed description will be omitted.

The movable motor 27 is attached to the outside of the support plate 24 provided on the lifting frame 22 and the jack bar 25 is installed through the support plate 24.

The position adjusting means includes a sensor unit 40 provided on each of the pressing plates for sensing contact with the bottled water package and a control unit for controlling the operation of the movable motor 27 based on the sensing state of the sensor unit 40 And a control circuit.

The sensor unit 40 includes a contact plate 42 protruding from the pressing plate and configured to contact the living water package as the pressing plate moves, as shown in FIG. 7, A support rod 44 that moves together with the plate 42, a spring 46 that elastically supports the contact plate 42, and a contact terminal that generates an electrical contact signal by the movement of the support rod 44 .

The contact terminal is preferably formed in the sensor housing 48 so as not to be exposed to the outside, and is a general configuration for generating an electric signal by a simple contact separation operation.

The elevating means includes a carriage 30 connected to the lifting frame 22 and having a plurality of casters 301 contacting the post frame 10 and a carriage 30 connected to the carriage 30 by a wire 32 A weight block 34 for attenuating the weight of the compression gripping module 20, and a lifting motor 36 for winding the wire 32.

The operation of the living water package laminating apparatus according to the present invention constructed as described above will be described below.

8A, before the bottled water package P enters the working position, the compression grip module 20 has a so-called upper height (not shown) so as not to interfere with the bottled water package P entering the working position, .

When the bottled water package P is transferred along the transfer line to reach the working position, the compression gripping module 20 is lowered to reach the so-called lower end height corresponding to the bottled water package P as shown in FIG. 8B 232, 233, and 234 are disposed in such a manner as to surround four sides of the bottled water package P, respectively.

The pressing plates 231, 232, 233 and 234 of the pressing and holding module 20 are moved by the moving means to urge the four sides of the bottled water package P in opposite directions to each other, So that the package P is gripped.

After the compressed water package P is stably gripped by the respective compression plates 231, 232, 233 and 234, the compression gripping module 20 is lifted by the lifting means, ) Is also lifted.

The operation of the elevating means is carried out in such a manner that the lifting motor 36 moves the wire 32 connecting the weight block 34 and the pushing and grasping module 20. This is the same as the operation principle of a general elevator, It is omitted.

As shown in FIG. 8C, after the lifting state of the bottled water package P is completed, another bottled water package P 'is conveyed along the conveying line to the working position and placed immediately below the lifted water package P And the slip sheet is put on the upper surface thereof in advance.

Then, as shown in FIG. 8D, after the lower water package P 'reaches the working position, the support support means returns to its original state, and then the compression grip module 20 descends to move the lifted water bottle package P are placed on the lower water package P 'with the slip sheet therebetween, so that the two water water packages P and P' are stacked.

After the two bottled water packages P (P ') are stacked, the compression plate of the compression gripping module 20 is returned to its original position as shown in FIG. 8E, so that the compression gripping state And the compression grip module 20 is returned to the original top height, so that the two stacked water packages P (P ') can be moved.

9, the pressing plates 231, 232, 233, and 234 are moved toward the pressing center point, so that the pressure holding gripping module 20 The spacing between the pair of pressing plates arranged opposed to each other is narrowed to press the bottled water package P placed at the working position, and the two pairs of pressing plates arranged opposite to each other perform the individual pressing action in the direction orthogonal to each other .

Therefore, it is important to apply the same pressing force to the four sides of the bottled water package P in order to properly perform the compression gripping action by each of the pressing plates. For this purpose, the bottled water package P is seated in the correct working position .

Here, the accurate working position means a central point at which the pressing gripping force formed by the combination of the respective pressing plates 231, 232, 233, and 234 is collected.

However, in the process of transferring the bottled water package P along the transfer line, the placement angle and position are generally shifted due to the influence of vibration or the like. Therefore, even if the bottled water package P stops at the position set at the working position, It can not be said that it is seated in position.

In addition, even if the moving speeds of the movable motors are set to be the same, the moving speeds of the respective pressing plates are also different from each other because the moving speeds are finely varied depending on various factors.

Therefore, even if the bottled water package is initially settled in the correct working position, the difference in the moving speed of each of the pressing plates 231, 232, 233, May occur.

As a result, when the compression plates 231, 232, 233, and 234 are accurately and simultaneously brought into contact with the bottled water package P when the compression plate is operated in a state in which the bottled water package P is not correctly seated in the working position, The pair of pressing plates 231 and 233 to which the pair of pressing plates 231 and 233 are applied first presses and holds the bottled water package P at an incorrect position.

Once the bottled water package P is pressed and held by a pair of pressing plates 231 and 233 at an incorrect position and fixed in position, even if pressed by another combination of pressing plates 232 and 234, There is a possibility that the same pressing force is not applied to the four sides of the bottled water package P as a result.

Therefore, in the present invention, the position adjustment means is used to perform the so-called position adjustment operation in which the bottled water package once transferred to the working position reaches the more accurate working position.

The contact plate 42 is first brought into contact with the bottled water package P while the pressing plate is moved to contact the bottled water package P by the sensor unit 40. At this time, As the movable member moves forward, it is relatively pushed back by the bottled water package, and the support bar 44 contacts the contact terminal to generate a contact signal.

In the control circuit connected to each of the sensor units 40, the order of each of the pressing plates adjacent to the bottled water package P is also grasped through the control circuit. In accordance with the order of the pressing plates adjacent to the bottled water package P, As shown in FIG.

The pressing plates 231, 232, 233, and 234 are sequentially referred to as No. 1 through No. 4, respectively, as follows. The sensor unit 40-1, the sensor unit 40-2, the sensor unit 40-3, the sensor unit 40-3, the sensor unit 40-3, the sensor unit 40-3, (40-4).

First, as shown in FIG. 10A, the first pressing plate 231 comes close to the bottled water package first, and the contact plate 42-1 and the bottled water package first make contact with each other, The first pressing plate 231 is directly pressed against the bottled water package (not shown) until the third sensor unit 40-3, which is opposed to the first pressing unit 231, senses contact with the bottled water package P P, at this time, the No. 2 pressing plate 233 and No. 4 pressing plate 234 are kept in a non-operating state.

Subsequently, when the distance between the No. 1 pressing plate 231 and the No. 3 pressing plate 233 becomes narrow and the contact with the bottled water package is detected by the No. 3 sensor unit 40-3 as shown in FIG. 10B, The first pressing plate 231 and the third pressing plate 233 are stopped.

That is, it can be seen that the position of the living water package P is adjusted on the moving line by the combination of the No. 1 pressing plate 231 and the No. 3 pressing plate 233.

At this time, the first pressing plate 231 and the third pressing plate 233 do not strongly press and hold the bottled water package P, and the contact plate 42 is pushed back and only a state of generating a contact signal is maintained.

Then, when the No. 2 sensor unit 40-2 senses the contact with the bottled water package P as shown in FIG. 10C, the No. 2 pressure plate 232 and the No. 4 pressure plate 234 are moved. The bottled water package P is moved until the fourth sensor unit 40-4 detects contact as in the previous case.

Since the contact plate 42 of the first and second sensor units 40-2 and 40-4 is only lightly held so as to be pushed backward as described above, The first pressing plate 233 can be moved smoothly.

10D, when the fourth sensor unit 40-4 senses the contact with the bottled water package, the bottled water package P is pressed against the second and fourth pressing plates 232 and 234 Its position is also adjusted on the moving line by the combination.

After the position of the bottled water package P is adjusted and finally settled in the correct working position as described above, the pressure plates 231, 232, 233, and 234 are simultaneously pressed to the center of pressure The pushing and grasping operation of the fresh water package P is completed and the pushing and holding module 20 is lifted and the fresh water package P is also lifted.
