Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The invention of this application relates to a chain loading device for a chain washer. More specifically, the present invention relates to a device that automatically inserts and supplies chain pieces into a device that cleans the inside of a drum using a chain or the like.

(Prior Art) The chain cleaning machine employing the chain feeding device of the present invention is mainly used as a part of the recycling process for used drums. The outline will be explained below.

(1) Shaping and pre-treatment process After removing the residue from inside the drum for recycling, the irregularities on the surface are shaped and sent to the internal pre-treatment cleaning process. In the internal pretreatment step, a spray nozzle is used to inject cleaning liquid at a constant high pressure into the drum, thereby efficiently performing pretreatment cleaning. The drum is then sent to an external cleaning device, which completely removes any external dirt.

(2) Main treatment cleaning and finishing process The drum cans that have been shaped and cleaned inside and out in the pre-treatment process are manually sent to an automatic washing machine, where the inside is completely cleaned for main processing. Rust removal, neutralization, degreasing, water washing, rust prevention, etc. are carried out. In this step, the caps of a pair of drums whose interiors have been completely cleaned are polished; hereinafter, the caps with a large diameter will be referred to as a large cap, and the cap with a small diameter will be referred to as a small cap. Next, an airtightness test is conducted using a drum leakage testing device based on predetermined standards, and only those that pass the standards are sent to a drying oven.
After passing through the drying oven, the drum can is placed in an automatic drying device to automatically dry the inside of the can, after which a final internal inspection is carried out and the cap is sealed with a finishing plug. The sealed drums are then completely painted in a painting process, and finally handed over to product management.

The present invention relates to a chain feeding device for supplying chain pieces to an automatic chain washer employed in the complete cleaning and finishing steps of the above-mentioned manufacturing process.

In a conventional automatic chain washer, as shown in FIG.
A plurality of chain pieces are manually inserted into the large spout 4 of the drum can, which is located with the large spout 4 and the small spout 6 of the top plate 2 of the drum can opened upwards. After injecting the cleaning liquid, the drum is moved to the roller conveyor device of the chain cleaning device, and the body 10 of the drum is placed on its side between a drive roller and an idle roller provided in the roller conveyor device. As the drive roller rotates, the drum D rotates while being supported by the pair of rollers. At the same time, the entire roller conveyor device, including the machine base, is centered around the longitudinal direction of the machine base, which is supported by horizontal frames provided front and rear parallel to the machine base.
A rocking device capable of tilting at a predetermined angle is activated to rock the roller conveyor device. Therefore, the chain piece and the cleaning liquid placed inside the drum can move within the can in response to the rocking and rotation effects, so that the inside of the can can be cleaned. In this way, when one cycle of cleaning action is completed, it is pushed out to another drum that is carried in subsequently, and the preceding drum is sequentially moved to another set of drive rollers and idle rollers provided on the roller conveyor device. It moves to a supported position, and at that position the same cycle of cleaning action as the previous one is performed. By sequentially continuing this cleaning cycle a predetermined number of times after adding the chain pieces, the drum is subjected to multiple rotations and rocking motions.
The inside of the drum is thoroughly cleaned. After a predetermined cycle of cleaning work has been completed, the drum cans are sent to another process.

(Problems to be Solved by the Invention) In the conventional example, the drum into which the chain piece has been introduced is placed on standby after one cycle of shaking and rotation of the drum that is first sent to the roller conveyor device is completed. The state in which the second drum is fed to the roller conveyor device is illustrated in the attached FIG. 11. A driving roller b mounted on a shaft d rotatably supported by a bearing c and an idle roller f mounted on a rotatable shaft e are provided on a machine stand a, and a loading plate h installed at an angle on a support column g is installed. First, the drum D-1 is fed in the direction of the arrow and placed on the drive roller b and idle roller f,
While the drum D-1 is also supported by the idle roller f and rotates due to the rotation of the drive roller b,
Since the swinging device of the machine base a including the roller conveyor device causes the machine base a to swing at a predetermined angle with the longitudinal direction as an axis, the chain piece and cleaning liquid put into the drum can D-1 are moved by the rotational movement, The drum moves within the can according to the movement of the drum caused by the rocking motion, and the inside of the can is cleaned.

When one cycle of cleaning work by rotation and rocking is completed, another drum can D-2 is supplied from the loading plate h installed on the support column g, and the preceding drum can D-1 is moved to the left (toward the drawing). As a result, the drum D-1 moves to the position shown by the chain line and is placed in contact with the drive roller b' and the idle roller f'. Instead, the drum D-2 moves to the original position D-1 and is supported by the drive roller b and the idle roller f. Next, when the two drive rollers b' and b rotate due to the operation of the drive device, the two drums D-1 and D-2, which are in line contact with each other, rotate in the direction of the arrow, and at the same time move the machine frame a. By the operation of a rocking device (not shown) provided in the roller conveyor device including
1 and D-2 also swing in a predetermined direction, and the second cycle of cleaning of the drum can is completed by rotation and swinging. Next, when another third drum can (not shown) that has been waiting is supplied from the carry-in plate h, the preceding drum can D-1,
D-2 is sequentially pushed forward and moves in the direction of the arrow. In this way, a plurality of drums D, for example, 8 drums D.
-1 to D-8 are placed on a roller conveyor device and 8 cycles of cleaning work are performed, and after the cleaning operation, drum D-1 is released from the support of the drive roller and idle roller at the end of the roller conveyor device. and then sent to other processes.

However, in order to send drums forward in a roller conveyor device, the drums that are waiting are moved one by one as they are fed from an inclined carry-in plate to the roller conveyor device.
This is possible only by pushing the drum cans forward one by one, so if the chain washer stops operating, the supply of drums from the loading plate is stopped, so the roller conveyor system has incomplete cleaning and other drums. There are a large number of drums left behind that cannot be sent to the process.
There were problems such as causing various problems in the work process and having a negative impact on improving efficiency.

However, before the drum can is cleaned, in order to insert the chain into the drum can, the cleaning chain piece and cleaning liquid were manually supplied into the large stopper of the drum can, which resulted in a decrease in work efficiency. Of course, the cleaning process that follows the chain loading process also poses a problem in that it obstructs the automation of other processes connected thereto.

(Means for Solving the Problems) Therefore, in the present invention, as a means to solve the above-mentioned problems, a chain feeding device is provided that automatically drops or supplies a cleaning chain piece and a cleaning liquid into the large stopper of a drum can. It is something to do.

In a chain insertion device that moves a chain hook holding a chain piece along an elevated track and drops the chain piece into a preset large tap opening of a drum at the end of the elevated track, the chain hook holding a chain piece is moved along an elevated track. A curved part is formed in the endless chain to be moved along the chain and a chain extrusion plate disposed at the end of the elevated track, and a chute plate is provided at a position where the chain piece comes off from the chain hook and falls when it comes into contact with this curved part. To provide a chain loading device for a chain washer, which is equipped with a device for supplying cleaning liquid into a drum after pieces are loaded into the drum from a chute plate.

That is, the chain feeding device has a chain conveyor elevated track for supporting and moving an endless chain that operates a chain hook on which a chain piece is hooked, and at the starting end of this track, the chain piece hooked on the chain hook is disposed on the chain conveyor. moves along the track and comes into contact with the curved part of the chain push-out plate provided on the support member at its terminal end, thereby coming off from the chain hook and passing through the large stopper of the drum can, which has been positioned in advance, and releasing the can. dropped inside. Also, cleaning liquid is automatically injected into the can through the large stopper by an injection device. The chain pieces and the washing liquid are put into the drum, and the injected drum is carried on a roller conveyor and pushed out to the chain washing device by the operation of the reversing feeding device.
Next, the chain cleaning device is equipped with multiple sets of drive rollers and idle rollers that support and rotate the body of the drum brought in by the reversing and feeding device, and while the drum is rotating, the chain cleaning device machine is moved in the direction of movement of the drum. In other words, it has a rocking device that tilts back and forth with the longitudinal direction as an axis, and is further supported by the drive roller and the idle roller, and when the drum rotates due to the operation of the drive roller, the rocking device operates and the machine is mounted. When the chain is tilted, the chain cleaning liquid introduced into the drum moves inside the drum, and when one cycle of cleaning action is completed, the body of the drum is pushed out and moved forward, and is supported on the next set of drive rollers and idler rollers. It has a drum extrusion feed device movable by an endless chain drive device.

(Function) Therefore, the chain pieces can be automatically and continuously fed into the large stopper of the drum, and the drum can in which the cleaning liquid has been automatically injected by the injection device is moved to its position and conveyed to the chain cleaning device. At the end of one cycle of cleaning work due to rotation and rocking of the drum, the drum is pushed out by the rollers of the drum push-out roller device, and the drum is continuously moved to the cleaning position for the next cycle according to the order, allowing automatic cleaning. Therefore, even if the chain washer stops operating, incompletely cleaned drums will not remain on the conveyor device.

(Example) A chain loading device for a chain washer according to the present invention will be described below with reference to the accompanying drawings.

The automatic chain feeding device is a starting end 14 of a chain conveyor elevated track 12 installed at a higher position than a roller conveyor device and a drum moving device, which will be described later.
At this point, the chain piece 16 is manually hooked onto one end of the chain hook 18. By moving the endless chain 20 attached to the other end of the chain hook 18, a bearing 22 attached to the intermediate portion of the endless chain 20 is moved.
moves sequentially in the direction of the arrow in the groove of the rail 24,
The terminal end 36 of the elevated track 12 is reached. Further, the elevated track 12 is provided with an endless chain housing cover 28 housing the endless chain 20, its moving rail 24, and a chain hook 18, and a chain holding plate 30 parallel to the endless chain storage cover 28, the end of which is curved toward the front. Further, a chain push-out plate 34 having a curved portion 32 substantially the same as the curved portion of the chain presser plate 30 is provided at the terminal end portion 36 . Therefore, the chain piece 16 that has been moved while being hooked on the chain hook 18 is attached to the chain pressing plate 30 and the chain pushing plate 3 at the terminal end 36 of the elevated track 12.
Between 4 and 4, the curved portion 32 of the chain extrusion plate 34
It touches and advances along the curved part, and finally it comes off the chain hook 18 at the end of the curved part and falls.

The chain piece 16 is dropped into the can from the large spout 4 of the drum can D via a chute plate 38 provided at a position where it comes off the chain hook 18 and falls. Further, a predetermined amount of cleaning liquid 42 is injected into the can via a pipe 44 by actuation of a solenoid valve 40 of a cleaning liquid injection device provided separately.

A mechanism 46 for moving and positioning the drum can D is disposed lower than the elevated track 12 so that the large spout 4 is located at an optimal position for the chain piece 16 to be inserted into the large spout of the drum can. . elevated track 12
The drums sent by a conveyor 47 provided close to the drum are supported by a roller conveyor 50 that can be raised and lowered, changed direction, sent to a positioning mechanism 46, supported by a plurality of rotating roller groups 48,
It rotates at a predetermined angle and is detected by a sensing means such as a sensor.
Positioning is performed by stopping the large stopper 4 of the drum D at an optimum position to receive the drop of the chain piece 16 from the chain hook 18. Since this positioning device is not an important element in the present invention, detailed explanation thereof will be omitted.

In this embodiment, the chain piece 16 is connected to the chute plate 3.
The cleaning liquid 42 is injected into the large tap 4 from the pipe 44 almost at the same time as the cleaning liquid 42 is poured into the large tap 4 through the drum 8. This cleaning liquid injection timing may be delayed from the injection of the chain piece 16, and may be carried out at the time when the drum can D is positioned by the positioning mechanism 46, or while the drum D is being moved to the next step on the roller conveyor 50 after the positioning is set.

Also, the shape of the chute plate 38 is as in this embodiment,
It may be formed to have a triangular cross section instead of a semi-cylindrical shape. By forming the chain piece 16 to have a triangular cross section, the chain piece 16 can be inserted into the large drum can opening 4 more smoothly and quickly.

As explained above, the drum in which the chain piece 16 and the cleaning liquid 42 have been dropped or injected into the large stopper 4 is moved forward (towards FIG. The chain is then reversed and transferred to the roller conveyor group of the chain cleaning device. That is, the rotating leg portion 5 of the reversing and feeding device 51
2, the top plate of the drum D is tilted forward by 90°, and further rotation of the charging arm 54 causes the body 1 of the drum D to be tilted forward.
0 is pushed in the direction of the roller conveyor group of the chain cleaning device. The drum can D is transported to a drive roller 68a and an idle roller 78a of a roller conveyor, which will be described later, via a loading plate 58 installed above a support column 56 of the chain cleaning device and inclined toward the chain cleaning device.
The torso 10 is moved to a position where it is supported between the two. In this case, the top plate 2 of the drum can D is located at the front as viewed in FIG. 1, and the base plate 8 is located at the front.

Next, a chain cleaning device closely related to the chain insertion device of the present invention will be explained.

In order to make the explanation easier and more accurate, the linkage relationship between the first drum D-1 and the push-out feed roller 86a will be explained first.

In FIG. 7, a drum D-1 is fed through an inclined loading plate 58 and supported by a drive roller 68a and an idle roller 78a. As the motor 72 operates, the pre-70 of the rotating shaft 66 around which the drive belt 74 is wound rotates. This movement results in rotation of the drive roller 68a in the direction of the arrow. In accordance with this rotation, the idle roller 78a also rotates in the same direction, so that the drum D-1 continues to rotate at the position P-1. At the same time, the motor 108 of the rocking device 94 starts and rotates the pinion 100 in the forward and reverse directions via the connecting member 110 and the pinion shaft 102. The gear member 96 also rotates forward and backward (clockwise or counterclockwise). Therefore, the frame formed by the inner and outer machine frames 64, 62, and 60 tilts and swings at a predetermined angle about the shaft 92 that connects the horizontal frame 90 and the outer frame 62 together with the members placed thereon. The chain piece 16 and the cleaning liquid 42 housed inside the drum D-1 move inside the drum in response to the rotation of the drum D-1 and the swinging motion, thereby cleaning the inside of the drum. Normally, the rocking motion is performed once on each side at an angle of about 50° with respect to the horizontal frame 90.

When one cycle of movement is completed as described above, the motor 108 of the rocker 94 stops, and the drive motor 112 connected to the shaft 82 of the engaged sprocket wheel 80 of the endless chain 84 is activated instead. The drive shaft 82 is rotated, and along with this rotation, the drum push-out feed roller 86a moves in the direction of the drive roller 68a, and the drum can D-1
