DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for receiving a plurality of solids which are continuously dropped and supplied at a predetermined position, sequentially receiving the solids at respective buckets, and raising the solids to a predetermined position. And a bucket-type conveyor that discharges in order from each bucket.

[0002]

2. Description of the Related Art As a conventional bucket-type conveyor relating to this, a conveyor as shown in FIG. 9 is suitably used. The bucket type conveyor 1 is a conveyor for conveying confectionery such as biscuits continuously supplied at a predetermined position to a predetermined position, and includes a plurality of buckets 4 for storing confectionery, and the buckets 4. And a belt conveyor body 2 for movement. The belt conveyor main body 2 is provided with a constant inclination so that the conveying end is higher, and a plurality of buckets 4 are attached to the belt 2b of the belt conveyor main body 2 at a constant interval in the conveying direction. .

The bucket 4 is a rectangular container having a wide receiving port 4e side, as shown in FIGS. 9 (A) and 9 (B).
It is formed in a side inverted trapezoidal shape. The bucket 4 has an inclined side surface 4k in surface contact with the belt 2b, and a center of the inclined side surface 4k is bolted to the belt 2b in a line in the width direction. When the bucket 4 is attached to the belt 2b, the receiving port 4e of the bucket 4 is substantially horizontal.

[0004] The confectionery continuously supplied at the carry-in end of the bucket type conveyor 1 is received by each bucket 4 and sent to the conveying end by the belt conveyor body 2. Here, as described above, since the inclined side surface 4k of the bucket 4 is in surface contact with the belt 2b, even if the supplied confectionery is not directly supplied into the bucket 4, the spilled confection is removed by the belt 2b. Led to. For this reason, the supplied confection does not fall out of the bucket type conveyor 1.

When each of the buckets 4 is sent to the transport end in this way, as shown in FIG. 9 (C), when the belt 2b is reversed at the transport end, the bucket 4 is also inverted, and the confection inside the bucket 4 is removed. It is discharged to a predetermined position.

[0006]

In the above-mentioned bucket type conveyor, since the bucket 4 is attached to the belt 2b by a plurality of bolts provided in a row in the width direction, manual operation is required when removing the bucket 4 from the belt 2b during maintenance. In this case, all the bolts must be removed, and the work is troublesome. Further, even if a part of the belt 2b is damaged, it is necessary to replace the part around the damaged part or the entirety thereof, so that the repair cost increases. Furthermore, it is difficult to remove the scum of the confectionery clogged in the gap between the bucket 4 and the belt 2b, and the cleaning is troublesome.

According to the first and second aspects of the present invention, the bucket can be easily removed from the conveyor body to facilitate cleaning and maintenance.
An object of the present invention is to reduce the repair cost of a conveyor by eliminating the need for a belt.

[0008]

The above object is achieved by a bucket-type conveyor according to the present invention. According to the present invention, the connection state of the first connection mechanism can be released by operating the connection release mechanism, and the bucket can be removed from the first round bar. Further, from this state, the connection state of the second connection mechanism can be released by moving the bucket in the radial direction with respect to the second round bar arranged next to the first round bar. That is, after the connection state of the first connection mechanism is released by the connection release mechanism, the bucket can be moved to release the connection state of the second connection mechanism, so that the bucket can be easily removed from the chain conveyor body. For this reason, cleaning and maintenance of the bucket type conveyor are facilitated. Further, the bucket is structured to be attached to the first and second round bars of the chain conveyor main body by the first connecting mechanism and the second connecting mechanism, and there is no belt in the conveyor main body as in the conventional case, so that the conveyor main body is damaged. Only parts can be repaired, and repair costs are reduced. Furthermore, there is no clogging of the conveyed material (solid matter) between the bucket and the conveyor, and the bucket type conveyor is less likely to become dirty. In addition, the second connecting mechanism connects the bucket and the second round bar so that the bucket and the second round bar can be relatively displaced in the traveling direction of the conveyor. Even if the linear distance to the rod changes, the change in the linear distance can be absorbed by the second connection mechanism.

The above-mentioned problem is solved by a bucket-type conveyor according to the second aspect. According to the present invention, at the position where solids are supplied, the receptacle of one bucket and the receptacle of the adjacent bucket partially overlap in plan view, so that even if solids fall out from one bucket, The solid is supplied to the next bucket. For this reason, without using a bucket and a belt as in the past,
Solids do not fall out of the bucket conveyor.

Is mounted. In addition, the carry-in section 21 carries out the
Guide rails 22c for guiding the respective roller chains 25 are laid between them up to 3. FIG. 1 shows only the main part of the guide rail 22c. Further, a press plate 22p for preventing the roller chain 25 from floating with respect to the guide rail 22c is attached to a bent portion between the carry-in portion 21 and the upright portion 22.

As shown in FIGS. 2 to 4, a plurality of sets of a first pipe 27a and a second pipe 27b are passed between the roller chains 25 in parallel. The first pipe 2
The pin 7a and the second pipe 27b are supported by the roller chain 25 by inserting pins (not shown) coaxially inserted into the rollers of the roller chain 25 from both sides of the pipe. And a set of first pipes 2
7a and the second pipe 27b make one bucket 40
Is attached to the chain conveyor body 20. That is, the first pipe 27a and the second pipe 27b correspond to the first round bar and the second round bar of the present invention.

The bucket 40 is an open-topped rectangular container for storing confectionery and the like, and has a receptacle as shown in the front view (A), side view (B), and plan view (C) of FIG. 4
The side is formed in a substantially inverted trapezoidal shape by a stainless plate (0.8 mm thick) so that the two sides are wide. A first connecting mechanism 45 and a second connecting mechanism 46 are attached to the first inclined side surface 43a of the bucket 40.

The first connecting mechanism 45 is a mechanism for connecting the first pipe 27a and the vicinity of the bottom of the bucket 40 so that the first pipe 27a and the vicinity of the bottom of the bucket 40 cannot be relatively displaced in the traveling direction of the conveyor and can be relatively rotated. One set is installed on each side. The first connection mechanism 45 is made of stainless steel, similarly to the bucket 40. FIG. 6 is a plan view (FIG. A) of the first connection mechanism 45, and a view taken in the direction of arrows BB in FIG.
FIG. 5A, a view taken along the line CC of FIG. A (FIG. C), and a view taken along the line DD of FIG. It should be noted that an L-shaped rod 47d described later is omitted in FIGS.

The first connecting mechanism 45 has a rectangular base plate 45p. On the surface 45u of the base plate 45p, a round bar storage part 4 is provided at the left corner in FIG.
5y, and a connection release mechanism 47 is mounted below the round bar storage portion 45y. The round bar storage portion 45y is composed of a pair of f-shaped vertical plates 45t erected on the base plate 45p, and as shown in FIG. 6B, the surface 45u of the base plate 45p and both vertical plates 45t.
The parallel inner wall surfaces allow the first pipe 27a to be restrained from three directions around it.

Further, an opening 45k is formed in a parallel portion of the two vertical plates 45t at a position substantially apart from the surface 45u of the base plate 45p by the diameter of the first pipe 27a, and the connection to the opening 45k is released. The distal end portion of the L-shaped rod 47d of the mechanism 47 is inserted. As a result, the first pipe 27a stored in the round bar storage portion 45y is restrained from four directions around, and the vicinity of the bottom of the bucket 40 is connected to the first pipe 27a by the first connection mechanism 45.

The connection release mechanism 47 is a mechanism for releasing the connection state of the first connection mechanism 45, and includes the aforementioned L-shaped rod 47d and a pair of bearings that support the L-shaped rod 47d so as to be able to advance and retreat in the axial direction. And a plate 47j. The L-shaped rod 47d is composed of a long axis having a tip portion inserted through the opening 45k and a short axis serving as an operation lever, and a ring-shaped spring seat 47z is provided at an intermediate position of the long axis. It is supported by a split pin 47w. The spring seat 47z of the L-shaped rod 47d is disposed between a pair of bearing plates 47j, and a spring 47s is mounted between the spring seat 47z and one of the bearing plates 47j. The spring 47s connects the L-shaped rod 47d to the vertical plate 45t.
The first connection mechanism 45 is held in a connected state in a state where no external force is applied to the short axis as the operation lever.

The back surface 4 of the base plate 45p
A guide plate 47x is fixed to the end of 5r for guiding the operation lever of the L-shaped rod 47d so that the direction of the operation lever does not change when the operation lever is pulled against the force of the spring 47s. The first connection mechanism 45 is positioned such that the long axis of the L-shaped rod 47d is parallel to both end faces 41 of the bucket 40 (see FIG. 5). The right half (see FIG. 6A) of the back surface 45r of the base plate 45p is welded and screwed to the first inclined side surface 43a of the bucket 40, so that the first connection mechanism 45 is attached to the bucket 40. Can be

The first connecting mechanism 45 and the bucket 40
Connecting mechanism 46 attached to the first inclined side surface 43a
Moves the vicinity of the receiving port of the bucket 40 to the second pipe 27b.
The mechanism is connected to the bucket 40 in such a manner that it can be relatively displaced in the traveling direction of the conveyor. The second connecting mechanism 46 is formed by forming a band-shaped flat plate into a substantially Z-shape. As shown in FIGS. 2, 3 and 5, the distal end side of the flat plate 46 and the first inclined side surface 43 a of the bucket 40 are connected to each other. Between the second pipe 27b
Can be sandwiched. The flat plate 46 is positioned parallel to both end surfaces 41 of the bucket 40, and the base end (not shown) of the flat plate 46 is welded to the first inclined side surface 43 a of the bucket 40. In addition,
The flat plate 46 is also made of stainless steel similarly to the bucket 40.

With this structure, the connection state of the second connection mechanism 46 can be released by moving the bucket 40 in the radial direction with respect to the second pipe 27b by a length equal to or longer than the distal end of the flat plate 46. However, in the state where the first connection mechanism 45 is connected, the amount of movement of the bucket 40 with respect to the second pipe 27b is limited, so that the second connection mechanism 46 is maintained in the connected state.

As shown in FIG. 2, the distance between the first pipe 27a and the second pipe 27b used as a set in the chain conveyor body 20 is determined by the distance between the first connection mechanism 45 and the second connection mechanism 46 of the bucket 40. It is set according to the distance between them. The distance between one set of first pipes 27a and the next set of second pipes 27b is
The distance from 0b to the end 42t of the receiving port 42 of the next bucket 40 is set to be about 35 mm. In addition,
The gap of about 35 mm is set in the concave portion on the track of the chain conveyor body 20, that is, between the carry-in portion 21 and the standing portion 22.
Compressed to about mm.

The bottom plate 40b of the bucket 40 is provided with an inclination, and when the bucket 40 starts rotating at the carry-in end and the carry-out end of the chain conveyor body 20, interference between the buckets 40 is prevented. Care is taken not to cause this. Further, the inclination θ of the first inclined side surface 43a with respect to the receiving port 42 of the bucket 40 is
1, the inclination is set substantially equal to the inclination (about 60 °) of the carry-in section 21 with respect to the floor surface so that the receiving port 42 of the bucket 40 is substantially horizontal. For this reason, the confectionery continuously dropped and supplied in the loading section 21 can be efficiently received in the bucket 40.

Further, since the receiving port 42 of the previous bucket 40 and the receiving port 42 of the next bucket 40 partially overlap in a plan view, the confectionery spilled from the previous bucket 40 is received by the next bucket 40. For this reason, the confectionery does not fall out of the bucket type conveyor 10 even if there is no belt on the conveyor as in the related art. Further, the second side surface 43 b located on the opposite side of the first inclined side surface 43 a of the bucket 40 is manufactured so as to be substantially perpendicular to the receiving port 42 of the bucket 40. Therefore, the second side surface 43b functions as a chute for guiding the confectionery spilled from the bucket 40 to the next bucket 40.

When the bucket 40 reaches the discharge end (upper end) of the discharge portion 23, the roller chain 25 follows the second sprocket 23e in an arc shape as shown in FIG. The straight line distance between the second pipe 27b and the second pipe 27b is reduced. However, while the first connecting mechanism 45 connects the first pipe 27a and the vicinity of the bottom of the bucket 40 so as not to be relatively displaceable in the traveling direction of the conveyor, the second connecting mechanism 46 connects the vicinity of the receptacle of the bucket 40 and the second pipe Since the second pipe 27a and the second pipe 27b are connected to each other so as to be relatively displaceable in the traveling direction of the conveyor, a change in the linear distance between the first pipe 27a and the second pipe 27b can be absorbed by the second connection mechanism 46.

Since the carry-out portion 23 of the chain conveyor body 20 is provided with an inclination of about 45 °, when the next bucket 40 is inverted at the carry-out end (upper end) and the confectionery inside is discharged. The confection does not hit the previous bucket 40.

Next, a procedure for removing the bucket 40 from the chain conveyor body 20 will be described with reference to FIG. First, as shown in FIGS. 7A and 7B, the operation lever of the L-shaped rod 47d of the connection release mechanism 47 is moved by a spring 47s.
6 and the end of the L-shaped rod 47d is opened by a hole 45k (see FIG. 6) of the vertical plate 45t of the first connecting mechanism 45.
(See). Thereby, the first connection mechanism 45
, The first pipe 27a can be taken out from the round bar storage part 45y, and the first connection mechanism 45 is in the disconnected state.

From this state, as shown in FIG. 7 (C), the bucket 40 is rotated upward about the second pipe 27b to move the first pipe 27a from the round bar storage portion 45y of the first connecting mechanism 45. Take out. Next, as shown in FIG. 7D, the bucket 40 is moved obliquely downward,
b, and the second pipe 27b is taken out from between the flat plate of the second connecting mechanism 46 and the first inclined side surface 43a of the bucket 40. Thus, the bucket 40 can be removed from the chain conveyor main body 20.
When the bucket 40 is attached to the chain conveyor body 20, the procedure is reversed.

Next, the operation of the bucket type conveyor 10 having the above structure will be briefly described. First, by driving the chain conveyor main body 20 by a motor (not shown), the plurality of buckets 40 connected to the chain conveyor main body 20 via the first connection mechanism 45 and the second connection mechanism 46 are loaded into the loading section 21. , And circulates between the standing portion 22 and the carrying-out portion 23 (see FIG. 1).

The confections continuously dropped and supplied on the front side of the carry-in section 21 are sequentially received by the buckets 40 moving in the carry-in section 21, and the buckets 40 carry out the confectionery via the upright section 22. It is sent to 23. Then, when the bucket 40 moves in an arc shape following the second sprocket 23e at the discharge end (upper end) of the discharge portion 23, the bucket 40 is inverted, and the confection inside is discharged to a predetermined position. The bucket 40 from which the confectionery is discharged in this manner moves from the back side of the unloading section 23 to the back side of the upright section 22 and returns to the loading section 21.

As described above, in the bucket type conveyor 10 according to the present embodiment, the first connection mechanism 4
After releasing the connection state of 5, the bucket 40 can be moved to release the connection state of the second connection mechanism 46, so that the bucket 40 can be easily removed from the chain conveyor body 20. For this reason, cleaning and maintenance of the bucket type conveyor 10 become easy. The bucket 40 is connected to the first pipe 27a and the second pipe 27 of the chain conveyor body 20 by the first connecting mechanism 45 and the second connecting mechanism 46.
b, and since there is no belt in the conveyor main body as in the related art, it is possible to repair only the damaged portion of the conveyor main body, and the repair cost is reduced. In addition, there is no inconvenience that the belt waste is mixed with the confectionery. Furthermore, there is no clogging of confectionery or the like between the bucket and the conveyor, and the bucket-type conveyor is hardly soiled.

In the bucket type conveyor 10 according to the present embodiment, the bucket 40 is connected to the first pipe 27a and the second pipe 2 via the first connecting mechanism 45 and the second connecting mechanism 46.
7b, and both pipes 27a, 27b are connected to the chain conveyor body 20 via pins. For this reason, frictional portions are dispersed between the bucket 40 and the chain conveyor body 20, and metal fatigue due to friction is reduced. Furthermore, since the bucket 40, the first connection mechanism 45, and the like are all made of stainless steel, they can be cleaned directly by pouring hot water.

(Second Embodiment) FIG. 8 is a front view (A), side view (B) and plan view of a bucket 60 used in a bucket type conveyor according to a second embodiment of the present invention. (Figure C). The bucket 60 is made thin by minimizing the dimension between the first inclined side surface 63a and the second side surface 63b. Further, the inclination θ of the first inclined side surface 63a with respect to the receiving port 62 is reduced so that the receiving port 62 can be widened.
As a result, the bucket 60 is
The space required for reversing between the carry-in end (lower end) and the carry-out end (upper end) can be reduced. Thus, for example, when the confectionery is discharged from the bucket 60, the falling distance of the confectionery can be reduced, and the confectionery is less likely to lose its shape.

As described above, in the first and second embodiments, the conveyor for transporting confectionery and the like has been described as an example, but it is also possible to transport solids other than confectionery. In addition, the inclination of the carry-in section 21 and the carry-out section 23 can be appropriately changed according to the installation location of the bucket type conveyor.

[0035]

According to the present invention, since the bucket can be easily removed from the chain conveyor main body, cleaning and maintenance of the bucket type conveyor become easy. In addition, since there is no belt in the conveyor body as in the related art, it is possible to repair only a damaged portion of the conveyor body, and the repair cost is reduced. Furthermore, there is no clogging of the conveyed material (solid matter) between the bucket and the conveyor, and the bucket type conveyor is less likely to become dirty.
