JPS5969320A - Continuous piling-up apparatus for box-shaped bodies - Google Patents

Abstract

PURPOSE:To reduce cost by a large margin by allowing the position of a lifting hook which lifts-up the both edges of a box-shaped body to be changed between thrust position and retreat position with respect to the locus of transfer of the box-shaped body and increasing the amount of the box-shaped bodies piled-up per hour. CONSTITUTION:In an apparatus for continually piling-up the box-shaped bodies which are transversely transported by a transport means, a driving wheel 2 which is driven by the motive power supplied from a driving apparatus and a trailing wheel 3 are rotatably supported in separated state in the vertical direction, onto a frame 1, and an endless body 4 is applied between the driving wheel and the trailing wheel. A lifting hook 5 which is engaged with the outside part (a) of the box-shaped body which is transversely transported and lifts-up the both edges of the box-shaped body is installed onto the endless body 4, and the box-shaped body held by the hook 5 is transferred in the locus of transfer in descent after ascent by the drive of the driving wheel, and the position of the hook 5 is changed between thrust position and retreat position with respect to the locus of transfer of the box-shaped body. With such a simple structure, the amount of piling-up can be increased above a prescribed amount.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a continuous stacking device for box-like bodies, specifically,
box (continuous product in order to stack -β bodies continuously)
fS'l to the device.

Conventionally, when cleaning and stacking large quantities of shopping baskets used in mass retailers such as supermarkets, they are stacked manually or by robots, but when done manually, the amount of stacking per unit of time is extremely small. Not only does this have poor work efficiency, but it also causes fatigue.In addition, when using a robot, the robot itself is expensive, which not only increases the cost of stacking, but also makes it difficult to hold and stack cleaned shopping baskets. During this time, it is necessary to reciprocate the arms of the robot both horizontally and vertically, so there is a large time loss between stacking, and the number of stacked boats per unit time is less than -1.
I couldn't do more than two.

The present invention was invented in view of the following two points, and the purpose is to have a simple structure, to be able to increase the amount of stacking per unit time to a predetermined amount or more, and to significantly reduce the cost required for stacking. The object of the present invention is to provide a device for continuously stacking box-like bodies.

Therefore, the present invention is a stacking device that continuously stacks box-like bodies that are transported laterally by a conveying means, and includes a stacking device that continuously stacks box-like bodies that are transported laterally by a conveying means,
At least one driving wheel and at least one driven wheel are spaced apart from each other and supported to rotate freely, and at least one endless body is suspended between the driving wheel and the driven wheel. A claw is provided to engage the outer side of the box-like body to be moved horizontally and lift the box-like body in a manner such that the box-like body is held on both sides, and the drive wheel is driven to lift the box-like body to The box-like body held by the claws is moved along a locus of movement in which it is raised and then lowered, and the lifting claws are moved to the entry position A; It is characterized by being able to change its position.

An embodiment of the stacking apparatus of the present invention will be described below with reference to the drawings.

The stacking device of the present invention continuously stacks mainly shopping baskets (A) which are washed by a washing device and then transported laterally by a conveying means such as a conveyor.

After the shopping basket (A) moves upward along the upward movement lines (4B) and (4a) of the endless body to the height position of the driven wheels (3), (3), the endless body moves upward. Move downward along the downward movement lines (4b) and (4b), and first move one [1

While moving along (4+1), they fit into the first shopping basket (A,) and are stacked. When this 111 is repeated, vil is recorded as shown in Figure 5.
- The claws (5) and (5) interfere with the outer edge surface of the first shopping basket (A1)σ) outer first knob (I'L), and due to this interference,
Enter the movement path of the shopping basket (8) and move to the second shopping basket (A).

As the endless body moves, the shopping basket (A) swings in the direction of retreating from the movement trajectory, retreats to the retreat position as shown in FIG. is disengaged and moves together with the endless bodies (4), (4). This second purchase 'tilt (A.

), the claws (5), (5) are removed from their own weight l.
This causes it to enter the movement trajectory of the shopping basket (A). By the rotational movement of the endless bodies (4), (4), the horizontally fed shopping baskets (A) are successively stacked one after another, and when this stacking reaches a certain amount li+, the detector (40') ) is activated, and the output signal from this detector (40) activates the carry-out device (20) to carry out the stacked shopping baskets from the stacked position to the side, and this carry-out causes the detector (50) to actuate. When activated, the kicking device (60) is actuated by the output signal from the detector (50), and kicks out the stacked shopping baskets in a direction perpendicular to the nil carry-out direction.

In the embodiment described below, two drive wheels (2) are used.
, (2) and two driven wheels (3), (3),
An endless body (4) between these driving wheels and driven wheels, respectively.
(4) is hung, but the driving wheel (2), the driven wheel (ro), and the endless body (4) may each be one, or six
There may be more than one.

In the case of one, for example, in one endless body (4), the first
A second holder is provided with three claws that can rotate freely relative to the endless body (4), and faces the first holder across the f+jl movement locus of the shopping basket (A). - a claw is provided so as to be freely rotatable relative to the endless body (4) through a 1% 1 section having a U-shaped cross section bent along the side edge of the front object 'R+ (A); The second lifting claw allows the ml basket (A) to be lifted on both sides.

Further, a large number of sets of the three holding claws (4), (4) are provided, but the number of sets is not particularly limited as long as it is one or more sets. But by providing multiple sets? 111. It is possible to increase the amount of accumulation per hour.

In addition, although it is preferable that the three claws (5), (5) for nil memory are formed horizontally 112 in pairs as shown in the figure, each piece should be formed in pairs. It may be formed into a structure. Further, the lifting claw (5) moves the shopping basket (A) due to its own weight U1. In addition to being pushed into the trace, it may be pushed in using a spring.

Further, the drive wheel (2) and the driven wheel (ro) may be a pulley, a roller, or the like, in addition to using a subwheel (J-kerato). In this case, instead of using a chino, an endless belt or an endless lobe may be used as the endless body (4).

In addition to baskets such as shopping baskets, the box-like bodies to be stacked may be boxes for storing beverage bottles or foodstuffs, or small containers.

As described below, according to the present invention, it is possible to continuously stack the box-like bodies that are transported laterally by the conveying means, and to increase the rotational movement speed of the endless body, or to increase the speed of the rotational movement of the endless body. By increasing the number of three claws, it is possible to significantly increase the stacking amount per time of about Qt, which is greater than the predetermined amount of stacking by a robot. Efficiency can be significantly improved.

All that is required is a frame, a driving wheel driven by power from the drive device, a driven wheel, an endless body suspended between the driving wheel and the driven wheel, and a lifting claw provided on the endless body. Because it has an extremely simple structure, it can be formed at a much lower cost than a robot, and combined with the fact that the number of stacks per unit time can be increased by more than a predetermined amount, it is possible to stack 1 to 9. It is extremely economical as it can reduce the cost to a large extent.
