Description

[Detailed Description of the Invention] The present invention relates to an improvement of a container cleaning device.

Conventionally, a container supply conveyor, a pair of endless conveyance belts with grippers that grip the containers supplied by the conveyor from both sides with grippers and convey them in reverse,
a container discharge conveyor that discharges the cleaned and drained containers while being reversely conveyed by the endless conveyor belt;
A container cleaning device has been proposed that is provided with a cleaning liquid pipe having a nozzle disposed below the container reversing path of the endless conveyance belt and facing the container to be reversed conveyed. , it was necessary to adjust the distance between the pair of endless conveyor belts with grippers, the position of the cleaning liquid piping, etc. according to the size of the container, and as each adjustment was done separately, the work was troublesome and the adjustment time was If it takes a long time and multiple rows of a pair of endless conveyor belts are provided,
There was a problem that made the adjustment even more complicated.

This invention was proposed in view of the above points,
The purpose is to provide a container cleaning device that can facilitate adjustment work corresponding to changes in container size.

The present invention consists of a container supply conveyor, a pair of endless conveyor belts equipped with grippers that grip the containers supplied by the conveyor from both sides with grippers and convey them in reverse, and cleaning and draining while the containers are being reversely conveyed by the endless conveyor belt. A container cleaning device comprising: a container discharge conveyor for discharging the containers that have been removed; and a cleaning liquid pipe having a nozzle disposed to face the containers to be reversely conveyed below the container reversal path of the endless conveyance belt. One of the conveyor belt guides on which the endless conveyor belt is mounted is rotatably supported by the main body frame,
A shaft is screwed onto a shaft rotated by an adjustment handle to be movable, and a shaft is rotated in conjunction with the shaft, and a slide guide that is integrated with the cleaning liquid pipe is screwed onto the same shaft. The main feature of the container cleaning device is that the amount of movement is set to 1/2 of the amount of movement of the conveyance band guide, and the distance between the pair of endless conveyance bands with grippers can be adjusted by simply rotating the adjustment handle. The position of the cleaning liquid piping can be adjusted to correspond to the size of the container, and the nozzle of the cleaning liquid piping can be adjusted to face the mouth of the container, making the adjustment operation extremely easy.

The present invention will be explained below based on examples.

1 to 3 show one embodiment.
2 is a container cleaning device body frame, and 3 is a curved chain conveyor for supplying containers, which is configured to curve as shown in the drawing along a guide (not shown). Reference numeral 4 denotes a curved chain conveyor for discharging containers after washing and draining, and like the curved chain conveyor 3, the conveyor 4 is designed to curve and travel along a guide. 5, 6, 7 are
Chain guides 8, 9, 1 are supported by the main body frame 2 as described later in an endless conveyor belt with grippers.
An endless chain 1 mounted between sprockets 11 and 12 rotatably supported at both ends of the chain 1.
3, 14, 15 and the same chain 13, 14, 15
Rubber gripper 1 for holding multiple containers attached to
6. Note that the endless chains 13 and 15 have a rubber gripper 16 attached only to one side, but the endless chain 14 in the center has rubber grippers 16 attached to both sides, and as shown in FIG. 2, the container 1 is clamped from both sides. It's becoming like that. Endless chains 13, 14, 15 are guided by upper chain rails 17, 18, 19 and lower chain rails 20, 21, 22 provided on chain guides 8, 9, 10, and are guided by endless conveyor belts 5, 6, 7 with grippers. is installed in a curved manner so as to pass below the intersection with the conveyors 3 and 4 for supplying and discharging the containers 1.

Of the chain guides 8, 9, and 10, the chain guides 8, 10 have a right-hand threaded portion 24 and An adjustment handle 28 is screwed into the left-hand threaded portion 25 via the threaded boss portions 26 and 27 and fixed to one end of the shaft 23.
The chain guide 9 in the center is positioned and fixedly supported so that the shaft 23 can be rotated through a bush. Penetrating.

29, 30 are endless conveyor belts 5, 6, 7 with grippers
The washing liquid piping is disposed along the path of the container 1 to face the container 1 that is being reversely conveyed by the pipe, and has a large number of nozzles 31 that spray the cleaning liquid onto the container along the piping direction.

The cleaning liquid pipes 29 and 30 are supported by lateral slide guides 32 and 33, and the lateral slide guides 3
2 and 33 are attached to a vertical slide guide 34 so as to be slidable in the horizontal direction, and the vertical slide guide 34 is supported by an elongated hole in the frame 2 and is screwed into the frame 2 rotated by a vertical adjustment handle 35. It is connected to a screw shaft 36 and is slidable in the vertical direction.

A shaft 37 is rotatably supported by the frame 2 and has a right-hand threaded portion 38 and a left-hand threaded portion 39, and threaded boss portions 40 and 41 integral with the lateral slide guides 32 and 33 are screwed together.

42 is a sprocket fixed to the shaft 23, 43
is a sprocket fixed to the shaft 37; 44 is a chain mounted between the sprockets 42 and 43; the shafts 23 and 37 are rotated in conjunction with each other;
Due to the pitch of the screws provided in 37, the amount of movement of the chain guides 8 and 10 is
The amount of movement of 9 and 30 is adjusted to 1/2.

In the above configuration, the containers 1 supplied by the conveyor 3 to the routes of the A row and the B row constituted by the endless conveyor belts 5, 6, and 7 are held between the rubber grippers 16, and are held between the rubber grippers 16. 7, the cleaning liquid pipe 2
A cleaning action is performed by a cleaning liquid sprayed from nozzles 31 provided at 9 and 30. After being washed as described above, water is drained during the remaining reversal conveyance process and returned to the upright state.

After washing and draining in this way,
It is discharged to the next process by the discharge conveyor 4. Here, if the size of the container 1 changes, the distance between the endless conveyor belts 5, 6, and 7 with grippers and the cleaning liquid piping 2 will change.
It is necessary to adjust the positions of 9 and 30. At this time, by rotating the handle 28, the shaft 23 is rotated, and the chain guides 8 and 10 are aligned with the opposite screws 2.
By the action of the screw bosses 26 and 27 that are screwed into the grippers 4 and 25, they move by the same amount in opposite directions, and the distance between them and the central guide 9 is changed. The interval is adjusted. on the other hand,
The shaft 37 is also rotated in conjunction with the shaft 23, and as a result, the horizontal slide guides 32 and 33 are moved by the same amount in opposite directions due to the action of the same screw as described above, so that the positions of the cleaning liquid pipes 29 and 30 are changed. is adjusted,
Since the amount of movement of the cleaning liquid pipes 29, 30 is 1/2 of that of the chain guides 8, 10, the nozzle 31 is always held by the gripper-equipped endless conveyor belts 5, 6, 7, and is conveyed in reverse. It will be located at the center of the container 1.

In addition, if the height of container 1 changes, handle 3
5 and move the vertical slide guide 34 up and down to move the cleaning liquid pipes 29 and 30 up and down to adjust their positions.

As described above, even when the size of the container 1 changes, the interval between the endless conveyor belts with grippers and the position of the cleaning liquid piping can be adjusted by simply rotating the handle, making the adjustment work extremely easy.

Although the above embodiment describes an example in which containers are fed in two rows, it is also possible to supply one or three or more rows, and one container may be repeatedly processed while being reversed and conveyed multiple times. You can also do it.
