Abstract

PURPOSE:To make discharging of a content easier by a method wherein an interval between a container box take-out device, which is connected to the carrying final end part at the top of a carrying path and carries a turned-over container box by pinching lateral side surfaces, and a content carrying conveyor, which carries a content taken out of the turned-over container box, is made larger toward the carrying final end side. CONSTITUTION:A container box is carried by a conveyor A and conveyor B while being pinched by them, and at the final end part of a carrying path F, the container box X is placed under a turned-over condition, and the turned over container box X is supported by a following container box take-out device 7, and a content is taken out while the container box X is being carried under the turned-over condition. At this time, an interval between the container box take-out device 7 which carried the turned over container box X and a content carrying conveyor 8 which carried the content taken out of the turned-over container box X is made larger toward the carrying final end side. By this method, the taking out of the content from the container box X can be performed satisfactorily.

Description

[Detailed description of the invention] The present invention relates to a storage box conveying device.

For example, as an example of a conveyance device having a portion for conveying a storage box while moving upward, there is a known one in which the storage box is inverted by an inverting device called an auto-dumber in order to take out the contents from the storage box, such as fruit.

This reversing device is configured to invert the storage box using, for example, a conveyor that draws an approximately semicircle, and a guide is provided opposite to the conveyor so that the storage box passes through this guide, thereby preventing the storage box from falling. The structure is designed to prevent

By the way, in such a conventional reversing device, there was a problem in which the contents in the storage box would fall one by one during the reversing process. Therefore, in order to make it easier to take out the contents of the storage box,
Containers were dropped at intervals between the conveyors.

Further, a problem arises in that a long distance between one box and the other on the conveyor is required, which reduces work efficiency.

The present invention has been made in order to improve the above-mentioned drawbacks.The present invention has been made in order to improve the above-mentioned drawbacks. Provides a conveyance device.

In order to achieve this object, the present invention provides a conveyor in which a conveyance surface having an approximately 'IL arc shape is formed and whose lower side is the conveyance starting end side, and a conveyor provided at a predetermined interval from the conveyor. A conveyor with a semi-circular conveyance surface forms a semi-circular conveyance path for conveying storage boxes with an open top surface,
a storage box take-out device connected to the upper transport end of the transport path and configured to grip and transport the inverted storage box by its side surfaces;
The content conveyor conveys the contents taken out from the inverted storage box, and the distance between the conveyor and the conveyor increases toward the end of the conveyance.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a front view thereof, in which A is a conveyor and B is a guide.

As the conveyor A, a slat conveyor is used in this embodiment. This conveyor A has 6 sprockets a
It is wound with I=86, and moves up and down from bottom to top in a roughly semicircular manner. The arrow is the direction of the movement.

The guide guide B is provided opposite the semicircular portion of the conveyor A at a predetermined interval.

This guide B also has a semicircular shape that follows the shape of the semicircular portion.

The storage box X is placed on the conveyor A, and is guided while its upper opening is closed by a guide B so that it moves upward and is reversed.

In the above configuration, a plurality of locking pieces 1 are provided on the conveyor A at predetermined intervals. This locking piece 1 protrudes so as to be movable forward and backward on the conveyor A, and is configured to protrude in a normal state and retract when the weight of the storage box X is applied by an advance/retreat device 2 to be described later. The shorter the installation interval of the locking pieces 1, the better, and in order to minimize the displacement of the storage box X, it is desirable to make it at least shorter than the width of the storage box X in the traveling direction.

Details of the locking piece 1 and the advancing/retracting device 2 are shown in FIGS. 2, 3, and 4. FIG. 2 is a partial plan view of the conveyance surface of the conveyor A seen from above, FIG. 3 is a sectional view taken along the line ■--■ in FIG. 1, and FIG. 4 is an enlarged side view.

In the figure, 50 is a frame of the conveyor A, on which a pair of subrockets a are pivotally supported. A chain 51 is engaged with the subrocket a, and the chain 5 1 ,
A plurality of U-shaped brackets 52 are passed between 5 and 1 to form a conveyor.

Note that 53 is a guide.

The locking piece 1 has a triangular cross section as shown in FIG. 4, and is attached to the center of the bracket 52 with its vertical surface 10 facing the direction of travel. The locking piece 1 is the bracket 5
It has an abutting surface 11 on the opposite side of the vertical surface 10 that abuts against the side surface 520 of 2, and is mounted on this abutting surface 11 by a pair of rivets 20 and a spring 21 so that it can protrude and retract.

That is, the contact surface 11 and the side surface 5 2 0 1. A through hole is formed at 4, through which a rivet 20 passes, and a coil spring 21 is fitted into the rivet 20 on the back side of the bracket 52. The spring 21 presses the contact surface 11 against the side surface 520, so that the locking piece 1 stands upright and projects upward in a normal state. This spring 2
1 is made strong enough to cause the contact surface 11 to separate from the side support 520 when the storage box X is placed on the locking piece 1. As a result, the slope 12 of the locking piece 1 comes into close contact with the upper surface of the bracket 52, and the locking piece 1 retracts. The rivet 20 and spring 21 form an advancing/retracting device 2.

In the above embodiment, the locking pieces 1 are attached to every other bracket 1, 52, but the present invention is not limited to this. In addition, various shapes other than the above-described embodiments, such as the shape of the locking piece 1 and the configuration of the advancing/retracting device 2, are possible. Furthermore, conveyor A may be other than a slat conveyor, and conveyor A
The positions and shapes of the guide B and the guide B may be reversed. Reference numeral 7 denotes a storage box take-out device for taking out the storage box, and 8 a contents transport conveyor for transporting the contents taken out from the take-out rT 9.

As is clear from the above, according to the configuration of the present invention, the storage box The stored items are taken out while being supported by the storage box take-out device 7 and transported while maintaining the inverted state.
The distance between the content transport conveyor 8, which transports the contents taken out from the inverted storage box Therefore, the contents can be taken out from the storage box X, preventing the contents from falling from the contents transport conveyor 8, and allowing the contents to be taken out from the storage box X in a good manner.
