Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device for pots used, for example, in the noodle manufacturing industry.

U.S. Patent Nos. 6,999,238 and 4,044,4
No. 20 includes a rotating brush and a direct-acting brush to clean the bread pan to remove seeds, crumbs and other debris left in the bread pan before making a new batch. A roasting pot cleaning brush assembly is shown. The straight brush oscillates back and forth to reach the corners of the pan, while the rotating brush performs its normal action. However, sometimes the depth is 7.
62cm, width 10.16C1rL.

If you use a deep bread pan with a length of 40.64α, the corners are very deep, so the brush may not be able to remove all the crumbs (especially in the corners) before moving them to the next pan.

The device shown in the above-mentioned patent is mounted above the ladle lta conveyor in the same manner as the device of the present invention. Accordingly, when reference is made to the aforementioned patents, detailed mounting and adjustment force methods are disclosed.

In the present invention, the brush is arranged diagonally with respect to the direction of movement, and the brush is vibrated up and down as the brush rotates, so that if the corner is a deep pot, it will be difficult to reach the corner, bread crust, etc. This is in response to the demand for removing

The present invention relates to a brush assembly for removing debris from a baking pan, which brush assembly includes: a brush assembly for removing debris from a baking pan; That is, at least one brush is rotatably mounted obliquely to the direction of movement of the pot past the brush, and the brush is reciprocated as the brush rotates, so that the ends of the bristles of the brush move downwardly as the brush rotates. This means that it is pushed up vertically and pushed to the corner of the pot. The rotating action of the brush sweeps the seeds and seeds out of the pot.

In a preferred embodiment, two brushes are used in such a configuration that their axes are arranged obliquely to the direction of movement and the axes are at an angle to each other. 2
The brushing paths of the two brushes overlap, but the overall width of the brushino crank is kept to a minimum. A normal vacuum head 9 is used on the downstream side of the two brushes (tandem type) as seen from the movement of the pot, and this head 9 has the function of removing debris swept out by the brushes from the pot. be. The vacuum head can also remove a complete loaf of bread that is left in the pan and is not removed during the normal removal process, into the vacuum system.

The method described in the aforementioned patent allows the entire brush assembly to be raised and lowered relative to the conveyor. For this purpose, a support rod can be installed that is rotated using a crank or a height adjustment.

The general relationship between the crank and the brush used in the pot cleaning device according to the present invention is described in U.S. Patent No. 999.23.
No. 8 and No. 4. Od No. 4,420.

And the mechanisms and brush drive means for supporting and driving the conveyor and supporting the main housing are schematically illustrated herein. However, the orientation of the brushes and the ability to drive them up and down constitute a disadvantage.

FIG. 1 will be explained. The bread pan cleaner, designated generally by the numeral 10, includes a conveyor assembly 11. As shown in FIG.

Conveyor assembly 11 includes a conveyor belt 12 driven by a motor 16 which drives belt support rollers in a conventional manner to move the belt in the direction indicated by arrow 15.

The conveyor frame 16 has side members and is supported on suitable feet or supports shown at 17.

The belt 12 is designed to support a plurality of pans 20. Usually, these bread pans 2o are 7.62cm
It has a depth of about 1. Groups or units of 2, 6, 4 or more pots. These bread pans are typically arranged along the length of the conveyor belt and each pan is placed perpendicular to the conveyor belt.

Then, as shown by arrow 15, it moves to pass through the bread pot cleaner 1°. Each of these bread pans has a fairly deep compartment, so it is important to remove various debris, such as breadcrumbs and bread crusts, from the bread pan before reusing it. need to be removed.

These pans are usually metal and correspond to the pan-cleaning steel shown in US Pat. No. 4,044,420, except that the individual compartments are deeper, longer and wider.

The outer housing 22 has side walls 22A and 22B, an input end wall 22C, and an output end wall forming an open bottom enclosure (see FIG. 6).

Housing 22 is mounted over four arms 26 and relative to conveyor frame 16. Each arm 26 is pivotally mounted to a respective sidewall of housing 22 at point 24 . The pivot 24 is disposed on the image side of the housing, and the pivot 24 is also disposed on both sides of the housing.

A pair of arms 26 is secured to the end of a shaft 25 which extends orthogonally to the conveyor and is rotatably mounted within a bracket 26. Bracket 26
are attached to the side members 16 of the conveyor frame. The arms or links 2 (two on each side) form parallel linkages for raising and lowering the nousing 22.

The shafts 25 lie below and perpendicular to the conveyor, and each shaft 25 has an arm O mounted to be driven below the conveyor.

The arm 30 has a drive link 1 with its both ends connected by reference numeral 620.
It is pivoted at a point. The arms 30 on both sides are parallel and therefore move simultaneously. The link 61 supports a threaded bracket 66, and a long crank 64 is screwed onto this bracket 63. As schematically shown in the figure, the load applied to the crank filter 4 is transmitted to the machine frame through the bracket filter 5. When the crank is rotated, the drive link 61 moves longitudinally, causing the shaft 25 and support arm or link 23 to pivot, thereby raising and lowering the entire housing 22.

Also, as schematically shown in the figure, U.S. Patent No. 4,044.42
As disclosed in No. 0 C. 5, a decompression head 40 is mounted at a predetermined position perpendicular to the conveyor.

The vacuum head 40 has a vacuum chamber 41 that communicates with a vacuum source 42. The chamber 41 is dimensioned to permit removal of debris from the individual pots 20. Also, the decompression head has a code 4 on its tip and rear end.
It has air pipes indicated at 6, which are supplied with air from a pneumatic source 44. Decompression hood 40
sucks in the debris, and air pressure from the orifice of pipe 46 blows the debris away. This is explained in U.S. Pat. No. 4,044. ! No. 120 and No. 5,999,2
As explained in No. 68.

The cleaning assembly of the device according to the invention includes a pair of rotatable brush assemblies, generally indicated at 49. Each of the plan assemblies 49 includes a core member 51 . and code 5
It includes a plurality of bristles, generally indicated schematically by 2. The construction of the plan is known and the bristles are made of nylon or a similar material of considerable stiffness. The diameter of the bristles is 0.32
cx is in the range of −0.48α and the length is 20.
It's only a matter of time.

Brush counterfeiting is entirely known, with each planar core member having a shaft 50 extending outwardly from both ends thereof. The shaft 50 is rotatably mounted in suitable bearings 56 disposed at each end of the brush, and the bearings 53 are mounted to a brush support pivot bracket 54. Each pivot bracket 54 is substantially identically constructed, but is mounted on opposite sides of the housing 220, so that its pivot axes are located on opposite sides of the conveyor.

Each of the figure 0 brackets 54 includes a side member 55 and an offset bracket portion 56, which members 55 and 56 are bent to wrap around the outer edge of the plano. Bracket portion 56A is located outside the path of rotation of the brush and extends inwardly from each end toward the center of the brush. The bracket 54 is integral with the portion 56 and the portion 56A.
2B includes a cross tie piece 58 that is close to 2B.

Each mounting has a bearing 60 attached to the foot 57, and a shaft 61 is attached to the bearing 6 of the foot 57.
It is arranged through 0. The shaft 61 is an intermediate shaft for driving the brush shaft 50, that is, a shaft used as a "slender" shaft, and a bracket 54 is attached to the shaft I.
form a pivot shaft for pivoting the brushes 49 up and down about the axis of each shaft 61.

As shown, each shaft 61 has a drive sprocket 65.
is installed, and the sprocket 65 is connected to the chain 65.
to drive the sprocket 67 of each shaft 50. Furthermore, a drive sprocket 70 is mounted externally to the sprocket 65 on the shaft 61, and a drive chain, indicated generally at 71, is driven by the motor-gear reducer top/2 of each brush. A motor gear unit top 72 is disposed above the top wall 22D of the housing 220 in any suitable manner. The individual motors are driven by a power source for driving each brush 49.

Brush assembly 49A is the leading brush.

That is, it is the first brush in a row of brushes. The intermediate shaft/pivot shaft 61 is then mounted in a bearing 75 mounted in a first bracket 76 near the input end wall 22G and in a place 76.
A is supported by the end wall 22G.

A second mounting bracket 77 is supported by the wall 22A,
A bearing 75 also rotatably and pivotally mounts the shaft 61 within such bracket.

Therefore, looking at FIG. 6, for example, the shaft 61 is connected to the side wall 22.
It can be seen that it is diagonal to A.

It can also be seen that it is oblique to the direction of movement of the conveyor belt, which is also indicated by arrow 15.

The aft plan of these two brush assemblies is designated 49B and has an intermediate/pivot shaft 61 attached to a first bracket 80. A first bracket 80 is supported on side wall 22B by a place 80A and is on the opposite side of brush assembly 49A relative to assembly d9A with respect to the direction of belt conveyor travel.
is located downstream of. The bracket 80 is the shaft 61
bearing 8 rotatably and pivotally mounted
1 is attached to one outer end. A second bracket 82 is attached to wall 22B and includes brush assembly 4.
A bearing 81 is provided for rotatably and pivotally mounting the intermediate/hibot shaft 61 of 9B.

The decompression head 9 in Fig. 6 is a brush assembly IJ 49 B.
It can be seen that it is immediately downstream of

It should be noted here that the shaft 61 of the brush assembly 49B is also placed at an angle to the conveyor travel direction and to the side wall 22B. However, since it is placed opposite to the plan assembly 49A, the first brush assembly 49A is latched in one direction, while the second brush assembly 49B is latched in the opposite direction. and the two brushes overlap each other in the direction across the conveyor. Although they overlap, a portion of one brush extends into the area covered by the other plan.

The purpose of configuring the brush in this manner is to provide a sufficient scrubbing action in the widthwise central portion of the housing along which the pot moves. Therefore, even if the bread pan is slightly displaced in the width direction of the housing, this rubbing action will not be affected.

In this way, each brush is individually rotated in the desired direction. Generally, the direction of travel of the bristles at the bottom is toward the center of the machine, as shown by arrows 85A and 85B in FIG. The angle between the axis of rotation of the brush and the direction of conveyor movement indicated by arrow 15 is approximately 20 degrees, and therefore also 20 degrees with respect to the side wall.

These plans 49 are separately driven by respective conventionally designed motor gear reducer units 72. The rotational speed when driven is 25 rpm to 25 rpm.

In order to promote the action of floating and dispersing debris such as seeds, bread crusts, bread crumbs, etc. from the corners of the bread pan ((, shaft 61
The rake is moved up and down cyclically about the axis defined by That is, the up-and-down cycling motion of the brush forces the bristles against the bread pan lengthwise, i.e., towards the ends, as the brush rotates, thereby penetrating the crumbs into the corners of the pan at the same time as the brush cycling. It produces bread crumbs.

Frame assembly 54 and brush 49 are counterbalanced to the ceiling frame of housing 22 using tension springs shown generally in FIG. As shown, a longitudinally extending tension spring 9D is employed in each frame, each spring being attached to a bracket 9D attached to a transverse member of the top wall 22D of the housing 220.
1 and a respective frame 54
The transition portion 56 of one arm member 55 and the bearing 56
has a second end connected to a bracket 96 that is mounted at a midpoint with the bearing mounting portion of the holder.

Since the tension of the spring 9o can be adjusted by appropriately adjusting one or both of the brackets 91 and 93, the balancing force for balancing the weight of the brush and the frame 54 can be controlled. Adjustments are made to apply a slight downward force to the brush, but the downward force is so slight that the brush is balanced to near balance.

The brush 49 and the botting frame 54 are reciprocated by an eccentric crank member 96 driven by an output shaft 97 of a motor gear reducer 98. A motor that can drive at the desired speed is selected. A crank pin, designated 100, acts on the rod end 9 bearing of the link 101. The link 101 is a bracket 102 that is pivotally supported on the rod end 10.
It is adjustable for. The rod ends are connected to fixed links 104 of each side member 55. Ink 104 is a strap permanently secured to one side member 55 of each brush assembly proximate spring mount 93 .

Since the crank stroke of pin 101] is about 2.54 cm, the total width of the vertical vibration of the brush indicated by arrow 110 is about 5.08 CIrL. This crank stroke can be adjusted as required.

To adjust K, just install an adjustable crank. When applied to the rotation of the crank disk 9, the speed of vibration corresponds to 100 to 175 rpm, and therefore about 10
It vibrates from 0 to 175 times/min.

The stroke of the brush's vertical vibration causes the bristles to move up and down inside the bread pan. As the brush moves up and down, it scrapes the sides of the bread pan, and at the same time, the rotation of the brush flicks debris away from the bread pan. Furthermore, the longitudinal force applied to the bristles causes them to stick up. The bristles are slightly curved,
Sweep out all the debris as you go to the very edge of the gun pot. In this way, a good rubbing action is achieved by the vibrations. At the same time, the debris is plucked, pushed, and finally swept away by the longitudinal forces involved in the rotation of the bristles.

Of course, the number of springs 90 attached to each brush assembly is not limited to one and may be two or more. Moreover, any desired device may be used as the device for attaching the spring. Similarly, if you want to increase or decrease the frequency, you can do that too. The travel stroke of the brush, indicated by arrow '110, can also be varied.

The various drive components are mostly shown schematically. When it comes to hearing, the basic components are brushes and housings.

and a brush rotation drive as illustrated in the inventor's previous patents. However, the improvement of oscillating the brush relative to the conveyor to obtain a force component along the axis of the plan bristles as the brush bristles rotate provides much more satisfactory debris removal than the device of the previous patent. The effect can be obtained.
